Notes:

Change in Reporting Currency and Exchange Rate Information

Our business is primarily conducted in China and all of our revenues are denominated in RMB. We used to use U.S. dollar as our reporting currenty. Starting from the third quarter of 2016, we changed our reporting currency from U.S. dollar to Renminbi. The aligning of the reporting currency with the underlying operations will better depict our results of operations for each period. Assets and liabilities of entities with functional currencies other than RMB are translated into RMB using the exchange rate on the balance sheet date. Revenues and expenses of entities with functional currencies other than RMB are translated into RMB at average rates prevailing during the reporting period. Prior periods’ financial information has been recasted as if we always used RMB as our reporting currency.

We make no representation that any RMB or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or RMB, as the case may be, at any particular rate, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of RMB into foreign exchange and through restrictions on foreign trade. On April 25, 2017,20, 2018, the noon buying rate was RMB6.8833RMB6.2945 to US$1.00.

The following table sets forth information concerning exchange rates between the RMB and the U.S. dollar for the periods indicated.

Risks Relating to Our Business

If we are not able to continue to attract students to enroll in our courses, our business and prospects will be materially and adversely affected.

The success of our business depends primarily on the number of students enrolled in our courses. Therefore, our ability to continue to attract students to enroll in our courses is critical to the continued success and growth of our business. This in turn will depend on several factors, including our ability to develop new courses and enhance existing courses to respond to changes in market trends and student demands, expand our learning center network and geographic footprint, manage our growth while maintaining consistent and high education quality, broaden our relationships with corporate employers and market our courses effectively to a broader base of prospective students, including young kids. Furthermore, our ability to attract students also depends on our ability to provide educational content that is perceived as more effective than the standard curricula of universities in China in terms of practical job-oriented training and as complementary to standard curricula of primary and secondary schools in China. If we are unable to continue to attract students to enroll in our courses, our net revenues may decline, which may have a material adverse effect on our business, financial condition and results of operationsoperations.

We may not be able to continue to recruit, train and retain qualified instructors and teaching assistants, who are critical to the success of our business and effective delivery of our education services to students.

Our instructors and teaching assistants are critical to maintaining the quality of our educational services and our reputation. We seek to hire highly qualified instructors with rich industry experience and strong teaching skills. As our kid education program continues to develop, we will need to recruit more teaching assistants. We recruit dedicated teaching assistants primarily from outstanding graduates of our courses. There is a limited pool of instructors and teaching assistants with these attributes and we must provide competitive compensation packages to attract and retain them. We must also provide ongoing training to our instructors and teaching assistants to ensure that they stay abreast of changes in curriculum, student demands, industry standards and other trends necessary to teach and tutor effectively. We have not experienced major difficulties in recruiting, training or retaining qualified instructors and teaching assistants in the past. However, we may not always be able to recruit, train and retain enough qualified instructors and teaching assistants in the future to keep pace with our growth and maintain consistent education quality. A shortage of qualified teaching staff, a decrease in the quality of our teaching staff’s classroom performance, whether actual or perceived, or a significant increase in compensation to retain qualified instructors and teaching assistants would have a material adverse effect on our business, financial condition and results of operations.

If we are not able to continually tailor our curriculum to market demand and enhance our courses to adequately and promptly respond to developments in the professional job market, our courses may become less attractive to students.

New trends in the global economy and rapid developments in the professional services industries may change the type of skills required for professionals in the marketplace. This requires us to continually develop, update and enhance our course materials to adapt to the needs of the professional job market in China. We may be unable to update our courses in a timely and cost-effective manner, or at all, to keep pace with changes in market requirements. Any inability to track and respond to these changes in a cost-effective and timely manner or to tailor our courses to the professional services markets in China would render our courses less attractive to students, which may materially and adversely affect our reputation and ability to continue to attract students and cause us to lose market share.

If we fail to develop and introduce new courses in anticipation of market demand in a timely and cost-effective manner, our competitive position and ability to generate revenues may be materially and adversely affected.

Since inception, our primary focus has been on providing IT professional education services. We have since expanded our course offerings to include non-IT training courses, including digital art, online sales and marketing and accounting. We have also launched IT and non-IT training courses customized for young kids since December 2015, which primarily include computer programming, robotrobotics programming, and digital arts (including 3D printing). and coding mathematics. We intend to continue developing new courses in anticipation of market demand. The introduction of new courses is subject to risks and uncertainties. Unexpected technical, operational, logistical, regulatory or other problems could delay or prevent the introduction of one or more new courses. Moreover, we cannot assure you that any of these new courses will match the quality or popularity of those developed by our competitors, achieve widespread market acceptance or generate the desired level of income for our students.

Offering new courses requires us to make investments in content development, recruit and train additional qualified instructors and teaching assistants, increase marketing efforts and re-allocate resources away from other uses. We may have limited experience with the content of new courses and may need to modify our systems and strategies to incorporate new courses into our existing course offerings. In offering courses in new subject areas, we may face new risks and challenges that we are not familiar with. Furthermore, we may experience difficulties in recruiting or otherwise identifying qualified instructors to develop the content for these new courses. If we are unable to offer new courses in a timely and cost-effective manner, our results of operations and financial condition could be adversely affected.

We rely on Java and digital art and web front courses for a majority of our total net revenues, and a decrease in the popularity and usage of Java technology,or Adobe design or web front technology would have a material adverse effect on our business and results of operations.

A majority of our total net revenues are generated from the Java and digital art and web front courses. In 2014, 2015, 2016 and 2016,2017, our Java course contributed 36.0%28.5%, 28.5%35.1% and 35.1% of our total student enrollments, our digital art course contributed 31.5%, 30.8% and 27.6%33.7% of our total student enrollments, and our web frontdigital art course contributed nil, 5.5%30.8%, 27.6% and 12.2%36.0% of our total student enrollments, respectively. The historical rapid growth of our business has been driven by the popularity and usage of Java technology and Adobe design, and web front development, and we expect net revenues from these courses to continue to represent a substantial portion of our total net revenues in the near future. We believe our reliance on Java and digital art and web front courses is mainly attributable to the wide adoption and popularity of Java technology and Adobe design and web front development.design. However, whether Java as a programming language or Adobe design technology as a digital art tool or web front development can maintain their popularity is beyond our control. Any factor that materially and adversely affects student enrollment in our Java or digital art or web front courses, such as a decrease in the popularity and usage of Java technology or Adobe design or web front development, would have a material adverse effect on business and our results of operations.

Our business depends on the market recognition of our brand, and if we are unable to maintain or enhance our brand recognition, our business, financial condition and results of operations may be materially and adversely affected.

We believe that the market recognition of our “Tarena” (达内) brand has significantly contributed to the success of our business and believe that maintaining and enhancing the reputation of this brand is critical to sustaining our competitive advantage. Our ability to maintain and enhance our brand recognition and reputation depends primarily on the perceived effectiveness and quality of our courses as well as the success of our marketing and promotion efforts. As we continue to grow and expand into new course areas, we may not be able to maintain the quality and consistency of our educational services as we did in the past. We have devoted significant resources to promoting our courses and brand in recent years, including Internet-based marketing and advertising, traditional media advertising and sponsoring industry trade seminars and software design competitions. However, our marketing and promotion efforts may not be successful or may inadvertently negatively impact our brand recognition and reputation. For example, if any governmental authority or competitor publicly alleges that any of our advertisements are misleading, our brand reputation may be adversely impacted. If we are unable to maintain and further enhance our brand recognition and reputation and increase awareness of our courses, or if we incur excessive marketing and promotion expenses, our results of operations may be materially and adversely affected. If we are unable to sustain our brand image, we may not be able to maintain premium tuition fees over our competitors, which may further exacerbate the extent of any adverse effect on our results of operations. Furthermore, any negative publicity relating to our company or our courses and services, regardless of its veracity, could harm our brand image and in turn materially and adversely affect our business and operating results.

We may not be able to maintain our high job placement rate for students, which could harm our ability to attract student enrollments.

We gather data on post-course job placement rates by conducting surveys of our graduates. Based on the survey responses, we calculate the six-month post-course job placement rates for a month by dividing (i) the number of job-seeking students enrolled in such month who (A) successfully graduated from our programs with graduation certificates awarded and (B) indicated that they had received employment offers within six months of graduation, by (ii) the total number of job-seeking students enrolled in such month who later successfully graduated from our programs with graduation certificates awarded. We calculate the average six-month post-course job placement rate for a year by averaging the six-month post-course job placement rates of each month of such year. Our average six-month post-course job placement rate for each of 20142015 and 20152016 was over 90%. When calculating such job placement rates for 20142015 and 2015,2016, a majority of the employment reported by relevant students werewas full-time employment, and a majority of the employment reported by relevant students werewas in the fields of their studies with us. All of the students enrolled in 20142015 and 20152016 who later successfully graduated from our programs with graduation certificates awarded and who were job-seeking, have filled out our surveys. Among the students enrolled in 20142015 and 2015, 89%2016, 86% and 86%88% of such students, respectively, graduated from our programs with graduation certificates awarded. Among the students enrolled in 20142015 and 20152016 who later successfully graduated from our programs with graduation certificates awarded, 81%77% and 77% of such students, respectively, were deemed to be job-seeking students.

Our student job placement rate depends on a wide range of external and internal factors. External factors include the macroeconomic conditions, the performance of the professional services sector in China and the recruiting demand of corporate employers. Internal factors include our education quality, the efforts of our career services personnel, our ability to provide adequate staffing to achieve desired results and our relationships with corporate employers. A number of such external and internal factors are outside of our control. Our historical job placement rates have been high. However, we cannot assure you that we will be able to maintain our current level of job placement rate for our students in the future. Any decrease in our job placement rate could harm our ability to recruit students, which may materially and adversely affect our business, financial condition and results of operations.

Our newly launched kid education programs may not be successfullysuccessful due to our limited experience in providing education services to minors.

In December 2015, we launched our new kid education programs under the brand nameTongcheng andTongmeiTongchengTongmei featuring IT training courses and non-IT training courses for kid students. In March 2016, we rolled out another kid education programTongchuang to offer kids robotics programming courses. In 2017, we continued to roll out a new kid education course in coding mathematics to further diversify our course offerings in kid education. Our new kid education programs target students aged between six and eighteen.eighteen, and are the most important part of our efforts to enter into the K-12 STEAM education market. As we have been primarily engaging in adult vocational training programs since our inception, we have very limited experience in providing education programs to minors, who have distinct learning preference and mentality as comparingcompared to adult students and require tailored courses and dedicated class management. Although the courses offered through our kid education programs are designed based on minors’ learning patterns and interests, we cannot guarantee you that our kid education programs will be able to continue to attract students or be proved to achieve satisfactory education results. If students lose interests in our kid education programs or find the courses offered in our kid education programs ineffective, our business, results of operations and financial conditions may be adversely affected.

Our enrollment rate could be impacted by the operations of academic K-12 education and tutoring service providers, given our target students have limited time and energy and they need to choose among different courses and programs. The K-12 education and tutoring market is highly competitive and the concept of STEAM education is relatively new in China. Students and their parents may prefer academic education and tutoring programs over our STEAM programs. We cannot assure you that we will be successful in competing for students, and if we fail, our financial status and results of operation will be adversely impacted.

In addition, unlike programs designed for adultIf the level of performance by the students of our kid education program deteriorates or satisfaction with our services declines, our business, financial condition, results of operations and reputation could be adversely affected.

The success of our business depends on our ability to deliver a satisfactory learning experience and improved educational results. Although the courses inprovided under our kid education programs are taughtdo not directly link to the academic performance of our students, their effectiveness could be evaluated by teaching assistants face-to-faceour students and their parents in offline classrooms. As a result,an intuitive way by referring to the improvements in programming skills or performances in robotics competitions. The performance of our students in the IT training courses, non-IT training course, and kid robotics programming course will impact the acceptance of, and the student and parent satisfaction with, our courses.

Accidents or injuries suffered by our students, their parents or other people caused by us, or perceived to be caused by us may adversely affect our reputation, subject us to liability and cause us to incur substantial costs.

We have a large number of minorsstudents and their parents attend classes on our premises to attend classes and/or use our facilities, and they may suffer accidents or injuries or other harm on our premises, including those caused by or otherwise arise from the actions of our employees or contractors.employees. Although we have enhanced preventive measures to avoid such incidents, we cannot assure you that there will be no any incident in the future.

We do not carry liability insurance for most of our students at our learning centers. In the event of accidents or injuries or other harm caused or perceived to be caused by us, our facilities and/or services may be perceived to be unsafe, which may discourage prospective students from enrolledattending our classes and participate in our programs.activities. We could also face claims alleging that we should be liable for the accidents or injuries, or we were negligent, provided inadequate supervision to our employees and therefore should be held jointly liable for harm caused by them. IfA material liability claim against us or any of these were to happen,our teachers or other employees could adversely affect our reputation, business, resultsenrollment and revenues. Even if unsuccessful, such a claim could create unfavorable publicity, cause us to incur substantial expenses and divert the time and attention of operations and financial conditions may be adversely affected.our management.

Our business, financial condition and results of operations may be adversely affected by a downturn in the global or Chinese economy.

Because our student enrollment may depend on our students’ and potential students’ levels of disposable income, perceived job prospects and willingness to spend, as well as the level of hiring demand of professional services positions, our business and prospects may be affected by economic conditions in China or globally. In addition, for our kid education programs, our student enrollment may depend on the disposable income and willingness to spend of the parents. The global macroeconomic environment is facing challenges, including the escalation of the European sovereign debt crisis since 2011, the end of quantitative easing by the U.S. Federal Reserve, the economic slowdown in the Eurozone in 2014 and and the expected exit of Thethe United Kingdom from the European Union. It is unclear whether the Chinese economy will resume its high growth rate. The Chinese economy has slowed down in recent years. According to the National Bureau of Statistics of China, in 2016,2017, China’s gross domestic product grew at a rate of 6.7%6.9%. There have been concerns over unrest in the Middle East and Africa, which have resulted in volatility in oil and other markets, and over the prolonged crisis in Ukraine which contributed to the collapse in the value of the Russian ruble, and the resulting Russian financial crisis. There have also been concerns about the territorial disputes involving China in Asia and the economic effects. Economic conditions in China, including the performance of the IT and other professional services industries, are sensitive to global economic conditions, as well as changes in domestic economic and political policies and the expected or perceived overall economic growth rate in China. A decline in the economic prospects of IT and other professionals could alter current or prospective students’ spending priorities and the recruiting demand from professional service industries. We cannot assure you that professional education spending in general or with respect to our course offerings in particular will increase, or not decrease, from current levels.levels, or if the macroeconomic environment deteriorates, parents will continue to spend on STEAM education for their children. Therefore, a slowdown in China’s economy or the global economy may lead to a reduction in demand for professional education services, which could materially and adversely affect our financial condition and results of operations.

If we fail to successfully execute our growth strategies, our business and prospects may be materially and adversely affected.

Our growth strategies include growing our student enrollments for existing courses, expanding our course offerings, further enhancing the quality of our education services and expanding our corporate employer network. We may not succeed in executing our growth strategies due to a number of factors, including, without limitation, the following:

If we fail to execute our growth strategies successfully, we may not be able to maintain our growth rate and our business and prospects may be materially and adversely affected as a result.

We may not be able to manage our business expansion effectively, which could harm our financial condition and results of operations.

We have expanded rapidly and we plan to continue to expand our operations in different geographic areas as we address the growth inof our customer base and market opportunities. We increased the number of our learning centers for professional education services from 118 as of December 31, 2014 to 145 as of December 31, 2016.2016 to 184 as of December 31, 2017. We also increased the number of our learning centers exclusively for kid education programs from 6 as of December 31, 2016 to 30 as of December 31, 2017. This expansion has resulted, and will continue to result, in substantial demands on our management, personnel and operational, technological and other resources. To manage the expected growth of our operations, we will be required to expand our existing operational, administrative and technological systems and our financial systems, procedures and controls and to expand training and management of our growing employee base. In addition, the geographic dispersion of our operations requires significant management resources. We cannot assure you that our current and planned personnel, systems, procedures and controls will be adequate to support our future operations, or that we will be able to effectively and efficiently manage the growth of our operations or recruit and retain qualified personnel to support our expansion. Any failure to effectively and efficiently manage our expansion may materially and adversely affect our ability to capitalize on new business opportunities, which in turn may have a material adverse effect on our financial condition and results of operations.

The growth of our business is in part dependent on our continuing access to a broad network of corporate employers.

We derive both direct benefits, such as increased enrollment driven by employer-specific customized courses, and indirect benefits, such as higher student job placement rate and strengthening of the Tarena brand, from our access to a large number of corporate employers. We believe our access to a large number of corporate employers in a wide range of industries is one of our core competitive strengths. If our access to these corporate employers were to become constrained or limited, or the benefits we derive from thesethis access were to be diminished, whether by our own actions or actions of our competitors, our growth prospects and our business would be harmed.

Our success depends on the continuing efforts of our senior management team and other key personnel and our business may be adversely affected if we lose their services.

Our future success depends heavily upon the continuing services of our senior management team. If any member of our senior management team leaves us and we fail to effectively manage a transition to new personnel, or if we fail to attract and retain experienced and passionate instructors, regional managers and other key personnel on acceptable terms, our business, financial conditions and results of operations could be adversely affected. We will need to continue to hire additional personnel, especially qualified instructors and regional managers, as our business grows. A shortage in the supply of personnel with requisite skills or our failure to attract and retain high qualityhigh-quality executives or key personnel could impede our ability to increase revenues from our existing courses, to launch new course offerings and to expand our operations and would have an adverse effect on our business and financial results.

Mr. Shaoyun Han, our founder, chairman and chief executive officer, has played an important role in the growth and development of our business since its inception. To date, we have relied heavily on Mr. Han’s expertise in, and familiarity with, our business operations, his leadership, and his reputation in the professional education services industry. If Mr. Han is unable or unwilling to continue in his present positions, we may not be able to easily replace him and may incur additional expenses to identify and train his successor. We do not maintain key man insurance on Mr. Han.

The operations of certain of our learning centers are, or may be deemed by relevant PRC government authorities to be, beyond their authorized business scope or without proper license or registration. If the relevant PRC government authorities take actions against such learning centers, our business and operations could be materially and adversely affected.

The principal regulations governing private education in China consist of theEducation Law of the PRC, thePrivate Education Law with its Amendment, and thePrivate Education Law Implementation Rules.See “Regulations—Regulations on Private Education—The Law for Promoting Private Education and theits Implementation Rules for the Law for Promoting Private Education. Rules.”

Under these PRC laws and regulations and related administrative requirements, private schools are classified as either non-profit private schools or for-profit private schools, and all kinds of private schools are required to obtain a school permit before their registration as legal entities with competent authorities. For-profit private training institutions shall be regulated and governed with reference to the abovementioned rules. To provide professional education services as a for-profit private school, a company may, in the capacity of a school sponsor, establish a private school which obtains a school permit from competent human resources and social security authorities.After obtaining a school permit, the registration of a private school will be completed once the competent industry and commerce administration authorities include the relevant professional education services in the authorized scope of business as specified in the business licenses of the private school. Under theAmendment to the Private Education Law and thePrivate Education Law Implementation Rules, a material change in a for-profit private school shall be approved by the competent education authorities or the authorities in charge of human resources and social security before it can be registered with the competent local branch of the State Administration for Industry and Commerce, or SAIC, the predecessor of the State Administration for Market Regulation newly established in April 2018.

However, since theAmendment to the Private Education Law just became effective on September 1, 2017 and the relevant detailed rules by national and most of the local government authorities have not been issued, there remains uncertainties about the registration process for the newly established private schools (including the private training institutions, similarly hereinafter) or the re-registration process for pre-existing private schools. In practice, the professional education services may be provided by a private school which holds a school permit issued by the human resources and social security authorities, under the Law for Promoting Private Education, and such a school can then establish and operate learning centers within the approved districtsregions to provide professional education services, provided that learning centers located outside the region of the registered address of the private schools shall be registered with original approving authorities. Alternatively, professional education services may also be provided by a company may obtainobtaining approval from the competent industry and commerce administration authorities to include the relevant professional education services in the authorized scope of business as specified in its business licenses.licenses, which approach has been adopted before the promulgation of theAmendment to the Private Education Law. A company with “professional education services” or an equivalent statement included in its approved scope of business can operate learning centers by itself or through its registered branches. On November 7, 2016, the Standing Committee of the PRC National People's Congress, or NPC, released the amendment of theLaw for Promoting Private Education, which will be effective on September 1, 2017, pursuant to which private schools are classified as either non-profit private schools or for-profit private schools. On December 30, 2016, theImplementation Rules for Private School Classification Registration was issued by the Ministry of Education, or the MOE, and other relevant authorities, which requires all private schools, including non-profit private schools and for-profit private schools, to obtain a “school permit”. Existing private schools that choose to register as for-profit private schools should apply for new school permits and complete the re-registration process. TheRegulatory Implementation Rules for Profitable Private School issued on December 30, 2016 further indicates that for-profit private training institutions shall be regulated with reference to such rules. The implementation of abovementioned regulations will also rely on detailed rules of local government authorities.

However,In addition, many local government authorities have different views on the relevant rules and regulations and have adopted different practices in granting school permits to private schools or issuing business licenses to companies that provide professional education services. Although some cities, such as Beijing, Shanghai and Hangzhou, allow companies to include “professional education services” in their business scope, the industry and commerce administration authorities in certain other areas have adopted regional policies of not allowing “professional education services” or similar statement to be included in the business scope of any company. In addition, when we applied for school permits or registrations of learning centers, the local human resources and social security authorities in some cities in China have either informed us that no school permits will be issued to new private schools in their jurisdictions or that they do not permit new learning centers established by private schools to be registered. These regional policies and practices have created significant obstacles for us to comply with all applicable rules and regulations for all of our local operations.

We use both ways discussed above to establish learning centers. As of December 31, 2016,2017, we had a total of 145214 learning centers, of which 4965 were managed by schools and 96149 were managed by our subsidiaries. Among the learning centers operated by our subsidiaries, 49 have neither professional education services nor education information related consultation as an authorized scope of business in the licenses of our subsidiaries or their registered branches operating these learning centers as of December 31, 2016,2017, and these learning centers in the aggregate accounted for 27.1%17.6% of our student enrollments in 2016.2017. We were not able to include professional education services in these companies’ authorized business scope mainly because the industry and commerce administration authorities in these areas have a general local policy prohibiting the inclusion of “professional education services” in the business scope of any company. In addition, nine13 learning centers operated by our subsidiaries only have “education information related consultation” rather than “professional education services” in their respective authorized scopes of business, and these learning centers in the aggregate accounted for 4.0%4.3% of our student enrollments in 2016.2017. The difference between “educational services” and “education information related consultation” is not very clear under applicable PRC laws and regulations, and it is possible that the relevant PRC government authorities may determine that operating learning centers in the way as currently conducted by our relevant subsidiaries is beyond the scope of “education information related consultation.” For these learning centers, we have been communicating, and will continue to communicate, with the competent industry and commerce administration authorities to expand the authorized business scope of the relevant subsidiaries to include “professional education services” or similar statement. For regions where it becomes apparent that we will not be able to expand the authorized business scope of the relevant subsidiaries, we will also explore the possibility of obtaining approval from the competent authorities to set up private schools to take over the operations of the relevant subsidiaries. If the relevant PRC government authorities discover or determine that our subsidiaries operate beyond their authorized business scope, they may order the relevant subsidiaries to complete the registration for change of business scope within a given period, failing which each company is subject to a one-time fine of RMB10,000 to RMB100,000, or may be ordered to cease its operation. We have been fined once for RMB50,000 for conducting business outside the authorized business scope since 2011.

For our learning centers operated by schools, we are also required to obtain and maintain various licenses and permits and make filings for each learning center with the competent human resources and social security authorities and civil affairs authorities. As of December 31, 2016, one of our learning centers are operated by schools outside their approved districts without obtaining relevant licenses and permits, and eight2017, 30 of our learning centers are operated by schools outside their registered address without being registered with the original approving authorities, which may subject us to fines of RMB10,000 to RMB50,000, confiscation of the gains derived from the noncompliant operations or the suspension of the noncompliant learning centers. These eight30 learning centers in the aggregate accounted for 4.4%18.3% of our total student enrollments in 2016.2017. As of the date of this annual report, all of our 25 schools have the school permit, among which two schools need to apply for updating their principal’s information. Besides, as of December 31, 2017, we have set up five (5) schools registered as schools requiring “reasonable returns” provided in thePrivate Education Law. We were unable to obtainare informed by the requisite permits or make the required filingslocal human resources and social security authorities in some districts becausecities in China that they have stopped issuing new school permits temporarily before any detailed implementing rules being issued.

During such transitional period between the promulgation of theAmendment to the Private Education Law and the issuance of the relevant detailed rules by national and most of the local government authorities, discontinued granting permits or accepting filingsthe above uncertainties and local policies and practices have created certain obstacles for administrative reasonsus to comply with all applicable rules and regulations for a periodall of time.our local operations. Although we have not been subject to any material fines or other penalties in relation to any non-compliance ofwith licensing requirements in the past with respect to our learning centers operated by schools, if we fail to cure any non-compliance in a timely manner, we may be subject to fines, confiscation of the gains derived from our noncompliant operations or the suspension of our noncompliant learning centers, which may materially and adversely affect our business and results of operation.

On February 13, 2018, the MOE and other relevant authorities promulgated theNotice on Effectively Reducing Extracurricular Burdens of Primary and Middle School Students and Conducting Special Administrative Actions for Off-campus Training Institutions, or theNotice, which proposes several rectification requirements on "test-oriented" non-academic cultural and educational training institutions and requires relevant government authorities to pay close attention to the "strong test-oriented" training, such as "advance teaching", especially mathematics and Chinese courses provided by the off-campus training institutions. According to theNotice, such off-campus training institutions shall obtain school permits and make filings regarding the classes, content, enrollment target and lecture time for disciplinary training with the local branches of the MOE. The coding mathematics course provided byTongchengTongmei shares similar content with elementary school mathematics courses, which may be regarded as the "strong test-oriented", and the informatics olympiad training organized under IT-training courses byTongchengTongmei may be regarded as the primary school competition-related courses, each of which may need to be rectified pursuant to theNotice. However, according to our oral consultation with the relevant local branches of the MOE, there has been no specific standards or implementation rules for theNotice and it is uncertain whether our coding mathematics course provided byTongchengTongmei or the informatics olympiad organized byTongchengTongmei are in compliance with theNotice. If our business is regarded as violating theNotice and we fail to cure any non-compliance in a timely manner, we may be subject to fines, confiscation of the gains derived from our noncompliant operations or the suspension of our noncompliant business, which may materially and adversely affect our business and results of operation.

We may lose market share and our profitability may be materially and adversely affected, if we fail to compete effectively with our present and future competitors or to adjust effectively to changing market conditions and trends.

The professional education services market in China is fragmented, rapidly evolving and highly competitive. We face competition in our offered courses and in many of the geographic markets in which we operate. As the IT professional education market in China matures, there is increased demand for highly specialized IT labor, and we may face competition from IT professional education providers that offer specialized training programs targeting certain niche job markets in the IT industry. In the future, we may also face competition from new entrants into the Chinese IT professional education market. As we expand beyond IT education into other fields of professional education, we also face competition for student enrollment from existing online and offline providers of professional education services, as well as smaller regional professional education services providers in China. Furthermore, we also face competition from providers of IT and non-ITother K-12 education programs to kids.service providers.

Some of our competitors may be able to devote more resources than we can to the development, promotion and provision of their education services and respond more quickly than we can to changes in student needs, market trends or new technologies. In addition, some of our competitors may be able to respond faster to changes in student preferences in some of our geographic markets and engage in price-cutting strategies. For our kid education programs, some of our competitors may have more experiences in designing courses based on minor’s preferences, mentality and learning curve. We cannot assure you that we will be able to compete successfully against current or future competitors. If we are unable to maintain our competitive position or otherwise respond to competitive pressure effectively, we may be forced to reduce our tuition fees and lose our market share, which will adversely impact our profitability.

Our business and financial results may be materially and adversely affected if we are unable to maintain our cooperative relationships with financing service providers for student loans.

In 2014, 2015, 2016 and 2016,2017, a substantial portion of our students relied on loans provided or arranged by a number of financing service providers to pay our tuition fees. In 2014, the financing service providers involved in tuition financing include Bank of China Consumer Finance Co., Ltd., or BOC CFC, CreditEase Business Consulting (Beijing) Co., Ltd., or CreditEase, and Bank of Beijing Consumer Finance Company, or BOB CFC. In 2015 and 2016, in addition to the above mentioned tuition financing services provided by those financing service providers, our students also took out loans facilitated through Baidu Small Loan Co., Ltd., or Baidu Small Loan, RenRenDai and ShiTuDai, consumer financing services provided by an independent third parties, to pay our tuitions. In 2014, 2015 and 2016, approximately 55.0%, 50.4% and 55.1% of our students took out loans provided or arranged by financing service providers to pay for our tuition fees.

We have entered into cooperative agreements with Baidu Small Loan Co., Ltd,Ltd. (or Baidu Small Loan) and Bank of China Consumer Finance Co., Ltd. (or BOC CFC and BOB CFCCFC), pursuant to which they provide loans to our students for the payment of our tuition fees. We have also entered into agreements with CreditEase Business Consulting (Beijing) Co., Ltd. (or CreditEase), RenRenDai and RenRenDai,ShiTuDai, whereby they assisted our students in obtaining loans to pay for our tuition fees. In 2015, 2016 and 2017, approximately 50.4%, 55.1% and 52.4% of our students received loans provided or arranged by financing service providers to pay for our tuition fees.

Our cooperative agreement with BOC CFC has expired in March 2017 and we are in the process of renewing our cooperative agreement with BOC CFC. However, we may not be able to renew our cooperative agreement with BOC CFC on commercially reasonable terms or at all. Moreover, Baidu Small Loan Co., Ltd., RenRenDai, BOC CFC, CreditEase, and ShiTuDaifinancing service partners have full discretion in deciding whether or not to extend or arrange for loans to a particular student. Furthermore, macroeconomic conditions in China may force the financing service providers to decrease or eliminate the amount of credit available for our students, making it difficult for our prospective students to afford our education. In addition, if the default rates on the loans provided or arranged by these and other financing service providers were to increase, they may raise the interest rates on the student loans, making such financing options less attractive to our students. Although peer-to-peer lending is generally protected as private loans between individuals under PRC law and has flourished in recent years in China, there are uncertainties as to the licensing requirements and the nature of business provided by those intermediaries, such as CreditEase, RenRenDai and ShiTuDai, in facilitating the peer-to-peer lending. According to theGuide to the Record-filing of Online Lending Information Intermediaries, issued in November 2016, or theRecord-filing Guidelines, and theNotice on Rectification and Inspection Acceptance of Risk of Peer-to-peer Lending, issued on December 2017, orCircular 57, certain local governmental authorities shall establish an inspection team to conduct risk rectification inspections on peer-to-peer lending information intermediaries within their jurisdictions. If onea peer-to-peer lending information intermediary institution passes the inspection, the local governmental authorities shall complete its record-filling under theRecord-filing Guidelines.Circular 57 also requires local governmental authorities to complete such record-filings of peer-to-peer lending information intermediaries within its jurisdiction by the end of April 2018, except that the deadline for certain complicated cases may be postponed to May 2018 or June 2018, as appropriate. According to theNotice of Further Regulating Campus Loans issued on June 29, 2017, theNotice of the Office of the Leading Group for the Special Campaign against Internet Financial Risks and the Office of the Leading Group for the Special Campaign against Peer-to-peer Lending Risks on the Regulation and Rectification of the “Cash Loan” Businessissued on December 1, 2017, the “campus loans” services shall be prohibited and the peer-to-peer lending institutions shall not provide loan to any student in school or any borrower without source of repayment or repayment capacity. If those peer-to-peer lending institutions could not complete the record-filings or the current services provided by peer-to-peer lending institutions to our student are prohibited, or more new PRC laws and/or regulations are passed in the future prohibiting peer-to-peer lending facilitated by, or imposing significant licensing requirements on, intermediaries such as CreditEase, RenRenDai and ShiTuDai, we cannot assure you that CreditEase, RenRenDai or ShiTuDai will be able to obtain relevant licenses and continue facilitating peer-to-peer lending in the future. If CreditEase, RenRenDai or ShiTuDai ceases to facilitate peer-to-peer lending to our students in the future, if our cooperative relationships with the financing service providers are damaged or lost, or if the financing service providers significantly increase their interest rates, our business and financial results would be adversely affected.

If we fail to protect our intellectual property rights, we may lose our competitive advantage and our brand and operations may suffer.

We consider our copyrights, trademarks, trade names and domain names invaluable to our ability to continue to develop and enhance our brand recognition. Unauthorized use of our copyrights, trademarks, trade names and domain names may damage our reputation and brand. Our major brand names and logos are registered trademarks in China. Our proprietary curricula and course materials, together with ourTarena Teaching System,, or TTS, are protected by copyrights. However, preventing copyright, trademark and trade name infringement or misuse could be difficult, costly and time-consuming, particularly in China. The measures we take to protect our copyrights, trademarks and other intellectual property rights are currently based upon a combination of trademark and copyright laws in China and may not be adequate to prevent unauthorized uses. Furthermore, application of laws governing intellectual property rights in China is uncertain and evolving, and could involve substantial uncertainties to us. There had been several incidents in the past where third parties used our “Tarena” (达内) brand without our authorization, and we had to resort to litigation to protect our intellectual property rights. These proceedings were all resolved in our favor and our brand and business were not materially harmed. However, if we are unable to adequately protect our trademarks, copyrights and other intellectual property rights in the future, we may lose our competitive advantage, our brand name may be harmed and our business may suffer materially. Furthermore, our management’s attention may be diverted by violations of our intellectual property rights, and we may be required to enter into costly litigation to protect our proprietary rights against any infringement or violation.

We may be subject to intellectual property rights claims or other claims which could result in substantial costs and diversion of our financial and management resources away from our business.

We cannot assure you that our course materials, other educational contents or other intellectual properties developed or used by us do not or will not infringe upon patents, valid copyrights or other intellectual property rights held by third parties. We have, and may from time to time be subject to legal proceedings and claims from time to time relating to the intellectual property of others. In addition, some of our employees were previously employed at other companies, including our current and potential competitors. To the extent these employees are involved in content development at our company similar to content development in which they have been involved at their former employers, we may become subject to claims that such employees or we may have used or disclosed trade secrets or other proprietary information of the former employers of our employees. In addition, our competitors may file lawsuits against us. Although we are not aware of any pending or threatened claims, ifIf any such claim arises in the future, litigation or other dispute resolution proceedings may be necessary to retain our ability to offer our current and future course materials or other content, which could result in substantial costs and diversion of our financial and management resources. Furthermore, if we are found to have violated the intellectual property rights of others, we may be enjoined from using such intellectual property rights, incur additional costs to license or develop alternative intellectual property rights and be forced to pay fines and damages, any of which may materially and adversely affect our business.

We recruit a significant portion of our students directly from our network of cooperative universities and colleges. If we lose these relationships, or the benefits we derive from these relationships diminish, our growth and our business may be harmed.

We have established various kinds of cooperative relationships with over 690750 universities and colleges in China. We enroll a significant percentage of our students directly from these universities and colleges through jointly offered majors, on-campus learning sites and university recruiting promotional events. We recruited approximately 14.8%15.7% of our students in 20162017 from these universities and colleges. If our relationships with any of these universities and colleges were to be damaged or lost, or the benefits we derive from these relationships were to be diminished, whether by our own actions, actions of one or more governmental entities or actions of our competitors, our growth and our business may be harmed.

Failure to control rental costs, obtain leases at desired locations at reasonable prices or protect our leasehold interests could materially and adversely affect our business.

A majority of our offices and learning centers are located on leased premises. At the end of each lease term we must negotiate an extension of the lease. If we are not able to negotiate an extension on terms acceptable to us, we will be forced to move to a different location, or the rent may increase significantly. This could disrupt our operations and adversely affect our profitability. All of our leases are subject to renewal at market prices, which could result in a substantial rent increase each renewal period. We compete with many other businesses for sites in certain highly desirable locations. As a result, we may not be able to obtain new leases at desirable locations or renew our existing leases on acceptable terms or at all, which could adversely affect our business. As of December 31, 2016,2017, we had received from our lessors copies of title certificates or proof of authorization to lease the properties to us for all leased properties. However, we cannot assure you that we will be able to obtain copies of title certificates or proof of authorization to lease any properties that we may lease in the future or the title to these properties we currently lease or any properties that we may lease in the future will not be otherwise challenged. Furthermore, several of our leased properties are owned by universities or built on allocated land in China. Such properties may not be legally leased to us under PRC law. Our leasehold interest in these properties may be challenged by relevant PRC governmental authorities to be invalid, and we may be forced to move out of such premises.

In addition, we have not registered most of our lease agreements with relevant PRC governmental authorities as required by PRC law, and although failure to do so does not in itself invalidate the leases, we may not be able to defend these leases against bona fide third parties. As of the date of this annual report, we are not aware of any actions, claims or investigations being contemplated by governmental authorities against us or our lessors with respect to the defects in our leased real properties or any challenges by third parties to our use of these properties. However, if any of our leases are terminated as a result of challenges by third parties or governmental authorities for lack of title certificates or proof of authorization to lease, we may not be able to protect our leasehold interest and may be forced to relocate the affected learning centers and incur additional expenses relating to such relocation. If we fail to find suitable replacement sites in a timely manner or on terms acceptable to us, our business and results of operations could be materially and adversely affected.

Our accounts receivable have been relatively high. Inability to collect our accounts receivable on a timely basis, if at all, could materially and adversely affect our financial condition, liquidity and results of operations.

Understanding the difficulty for recent college graduates to afford the tuition fees of our courses, we offered qualified students the post-graduation tuition payment option beginning in 2006, which led to our relatively high accounts receivable. As of December 31, 2014, 2015, 2016 and 2016,2017, our outstanding accounts receivable, net of allowance for doubtful accounts, were RMB151 million, RMB155 million, RMB99 million and RMB99RMB231 million, respectively. Although we conduct financial evaluations of our students applying to use our post-graduation tuition payment option, we do not require collateral or other security from our students. Adverse changes in the macroeconomic environmentalenvironment and the earnings capacity of our students may negatively impact our ability to collect our accounts receivable. Furthermore, as time passes, it might be more difficult for us to collect historical accounts receivables. Our bad debt allowance increased significantly between 2014 and 2015. In 2015, we observed an increase in the overall account aging for students enrolled between 2010 and 2014 who used the post-graduation payment option, as well as an increase in the cumulative default amount of accounts receivablecharged to expense decreased from such students. As a result, we determined that the delinquency risk for the corresponding accounts receivable has increased as well. In 2016, our bad debt allowance decreased considerably from RMB63.1 million in 2015 to RMB33.6 million in 2016.2016 to RMB31.5 million in 2017. However, there is no guarantee that our bad debt allowance and delinquency riskexpense will keep decreasing in the following years. Our inability to collect our accounts receivable on a timely basis, if at all, could cause our bad debt allowance to increase or remain relatively high in the future, and materially and adversely affect our financial condition, liquidity and results of operations.

Capacity constraints of our learning centers could cause us to lose students to our competitors.

Our learning centers are limited in size and number of classrooms. We may not be able to admit all students who would like to enroll in our courses due to the capacity constraints of our learning centers. If we fail to expand our physical capacity as quickly as the demand for our classroom-based services grows, we could lose potential students to our competitors, which could adversely affect our results of operations and business prospects. As we further expand our kid education programs, we may face more intense capacity challenges.

We may not be able to recoup the capital expenditures or investments we make to expand and upgrade our teaching, administrative, research and other capabilities.

We purchased two office buildings in Beijing for an aggregate price of RMB231.9millionRMB231.9 million in 2016. The office buildings are mainly for teaching purpose, and to a lesser extent for an administrative function. We also purchased a building in Qingdao and another one in Haikou for an aggregate price of RMB49.6 million in 2016. The purpose of these two buildings is for teaching purposes as learning centers to accommodate the growing demand in local market and enjoy local favorable policies. We may continue to invest in our teaching, administrative, research and other capabilities as our business further develops. Although we will evaluate the feasibility of each property purchase for the good of business operation, we are likely to incur costs associated with these investments earlier than some of the anticipated benefits and the return on these investments may be lower, or may develop more slowly, than we expect. We may not be able to recover our capital expenditures or investments, in part or in full, or the recovery of these capital expenditures or investments may take longer than expected. As a result, the carrying value of the related assets may be subject to an impairment charge, which could adversely affect our profitability.

Our strategy of investments and acquiring complementary businesses and assets may fail.

As part of our business strategy, we have pursued, and intend to continue to pursue, selective strategic investments and acquisitions of businesses and assets that complement our existing business. Investments and acquisitions involve uncertainties and risks, including:

Any failure to address these risks successfully may have a material and adverse effect on our financial condition and results of operations. Investments and acquisitions may require a significant amount of capital investment, which would decrease the amount of cash available for working capital or capital expenditures. In addition, if we use our equity securities to pay for investments and acquisitions, we may dilute the value of our ADSs and the underlying ordinary shares. If we borrow funds to finance investments and acquisitions, such debt instruments may contain restrictive covenants that could, among other things, restrict us from distributing dividends. Moreover, acquisitions may also generate significant amortization expenses related to intangible assets. We may also incur impairment charges to earnings for investments and acquired businesses and assets which are determined to be impaired, and recognize the proportional share of the net losses of the investees to the extent of the amount of the investments for the equity method investments.

GeographicThe geographic concentration of our learning centers may unfavorably impact our operations.

We derive a substantial portion of our net revenues from our entities in Hangzhou and Beijing. Revenue derived from the entities in Hangzhou accounted for 25.5%33.0%, 33.0%31.9% and 31.9%30.0% of our net revenues in 2014, 2015, 2016 and 2016,2017, respectively. Revenue derived from the entities in Beijing accounted for 15.5%, 12.3%,12.4% and 12.4%13.0% of our net revenues in 2014, 2015, 2016 and 2016,2017, respectively. As a result of this geographic concentration, our results of operations are significantly affected by economic conditions in Hangzhou and Beijing. Furthermore, any natural disaster or health epidemics affecting the Hangzhou and Beijing regions could significantly impact our operations. Although we have been and will be exploring opportunities of setting up additional learning centers in second tier or third tierthird-tier cities, we expect that we will continue to derive a substantial portion of our net revenues from Hangzhou and Beijing in the near future. Deterioration in economic conditions and the professional services industries in these markets could decrease the demand for our courses, which in turn could negatively impact our operations and business prospects.

Our historical financial and operating results, growth rates and profitability may not be indicative of future performance.

Although we commenced operations in 2002, our significant business growth and expansion began in 2009. Our business and our prospects must be evaluated in light of the risks and uncertainties encountered by companies at a comparable stage of development. In addition, the professional education services market in China is still at an early stage of development, which makes it difficult to evaluate our business and future prospects. Furthermore, our results of operations may vary from period to period in response to a variety of other factors, including general economic conditions and regulations, government actions pertaining to the professional education services sector in China, changes in spending on professional education services, our ability to control cost of revenues and operating expenses, and non-recurring charges incurred in connection with acquisitions or other extraordinary transactions or under unexpected circumstances. Due to the above factors, some of which are beyond our control, our historical financial and operating results, growth rates and profitability may not be indicative of our future performance and you should not rely on our past results or our historic growth rates as indicators of our future performance.

Our ability to broadcast our lectures live and to offer online learning modules on TTS depends upon the performance and reliability of our systems and the Internet infrastructure and telecommunications networks in China.

We deliver live broadcasts of our lectures via a dedicated network provided by China Telecom and China Unicom to terminals located in selected learning centers with high student enrollment and via public Internet infrastructure to other learning centers. Any unscheduled service interruption of the Internet infrastructure and telecommunications networks in China could cause us to be unable to deliver these live broadcasts, forcing us to resort to using pre-recorded lectures in the event of such service interruptions. Our inability to broadcast live lectures during service interruptions may damage the quality of our education and student experience, which may hurt our reputation and negatively impact our financial condition and results of operations. Furthermore, our gross profit and net income could be adversely affected if the prices that we pay for telecommunications and Internet services rise significantly.

Our ability to offer online learning modules also depends on the performance and reliability of the Internet infrastructure in China. Disruptions to the Internet infrastructure of China may deny our students access to the learning functionalities on our TTS orTMOOC.cn, which may hinder students from effectively learning our education contents. Furthermore, increases in the traffic on TTS orTMOOC.cn could also strain the capacity of our existing computer systems, which could lead to slower response times or system failures. This would cause a disruption or suspension in our course offerings, which would hurt our brand and reputation and negatively affect our revenue growth. We may need to incur additional costs to improve our systems in order to accommodate increased demand if we anticipate that our systems cannot handle higher traffic volume in the future.

Our new CRM system may not function properly, which may materially and adversely affect our operations

We switched to a new customer relationship management, or CRM system, in August 2015. The new CRM system is developed in-house and is intended to improve functionality and information flow. As with any major new software system, there are inherent risks in the design, construction, implementation and operation of our new CRM system. These risks include the potential failures to properly design the system, to efficiently construct and implement the system and to effectively operate the system. While we believe that our new CRM system will provide the anticipated IT and customer service enhancements we expect, no assurances can be given in this regard. The failure to properly and efficiently operate the new CRM system could disrupt our operations and adversely affect our financial results.

Accidents or injuries suffered by our students or other people on our premises may adversely affect our reputation, subject us to liability and cause us to incur substantial costs.

We do not carry liability insurance for most of our students at our learning centers. In the event of accidents, injuries or other harm to students or other people on our premises, including those caused by or otherwise arising from the actions of our employees on our premises, our facilities may be perceived to be unsafe, which may discourage prospective students from attending our classes. We could also face claims alleging that we were negligent or provided inadequate supervision to our employees and therefore should be held jointly liable for harm caused by them or are otherwise liable for injuries suffered by our students or other people on our premises. A liability claim, even ofif unsuccessful, against us or any of our employees could adversely affect our reputation, enrollment and revenues, causing us to incur substantial expenses and divert the time and attention of our management.

If we fail to maintainimplement an effective system of internal controls, we may be unable to accurately report our results of operations or prevent fraud or fail to meet our reporting obligations, and investor confidence and the market price of our ADSs may be materially and adversely affected.

We are subject to reporting obligations under the U.S. securities laws. Among other things, the Securities and Exchange Commission, or the SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, adopted rules requiring every public company, including us, to include a management report on the company’s internal control over financial reporting in its annual report, which contains management’s assessment of the effectiveness of the company’s internal control over financial reporting. In addition, once we cease to be an “emerging growth company,” as such term is defined in the Jumpstart Our Business Startups Act of 2012 (as amended by the Fixing America’s Surface Transportation Act of 2015), or the JOBS Act, our independent registered public accounting firm may be required to report on the effectiveness of our internal control over financial reporting.

Our

As a result of management’s assessment, our management identified a material weakness as of December 31, 2017, which was the insufficient review in areas subject to significant estimates and judgments. See “Item 15. Controls and Procedures.” This material weakness may result in a material misstatement to our quarterly or annual consolidated financial statements that would not be prevented or detected. As a result of the material weakness, management has concluded that our internal control over financial reporting was effectiveineffective as of December 31, 2016. See “Item 15. Controls2017.

Our management has been engaged in, and Procedures.”Incontinues to be engaged in making necessary changes and improvements to the future, however, if we failoverall design of its control environment to maintain effectiveaddress the material weakness in internal control over financial reporting and the ineffectiveness of our managementdisclosure controls and procedures described above.

To remediate the material weakness described above with respect to controls over the period-end financial statement reporting and controls over significant complex transactions, we plan to continue to: (i) reinforce the oversight and review procedure over areas subject to significant estimates and judgments; and (ii) enhance our accounting manual to provide our accounting team with more comprehensive guidelines on the accounting policies under U.S. GAAP and SEC rules and requirements. We plan to continue to assess our standardized processes to further enhance the effectiveness of our financial review, including the analysis and monitoring of financial information in a consistent and thorough manner.

We expect that we will incur more costs in the implementation of such measures. However, the implementation of these measures may not be able to conclude that we have effectivefully address the material weakness in our internal control over financial reporting at a reasonable assurance level. Areporting. Our failure to achievecorrect the material weakness and maintain effective internal controls over financial reportingcontrol deficiency or our failure to discover and address any other material weakness or control deficiencies could result in inaccuracies in our financial statements and could also impair our ability to comply with applicable financial reporting requirements and related regulatory filings on a timely basis. As a result, our business, financial condition, results of operations and prospects, as well as the trading price of our ADSs, may be materially and adversely affected. Moreover, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions. We may also be required to restate our financial statements from prior periods.

Furthermore, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, as a public company, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future. We may be unable to timely complete our evaluation testing and any required remediation. If we fail to maintain an effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could in turn limit our access to capital markets, harm our results of operations and lead to a decline in the trading price of our ADSs. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions.

We have limited insurance coverage for our operations in China.

Insurance companies in China currently do not offer as extensive an array of insurance products as insurance companies do in more developed economies. We have determined that the risks of disruption or liability from our business, the loss or damage to our fixed assets, including our equipment and office furniture, the cost of insuring for these risks, and the difficulties associated with acquiring such insurance on commercially reasonable terms render it commercially impractical for us to have such insurance. As a result, we do not have any business interruption, litigation or property insurance coverage for our operations in China. Any uninsured occurrence of personal injury, loss or damage to fixed assets, or litigation or business disruption may result in the incurrence of substantial costs and the diversion of resources, which could have an adverse effect on our operating results.

Our business is subject to seasonal fluctuations, which may cause our operating results to fluctuate from quarter to quarter. This may result in volatility in and adversely affect the price of our ADSs.

We have experienced, and expect to continue to experience, seasonal fluctuations in our net revenues and results of operations, primarily due to seasonal changes in student enrollment. Historically, our courses tend to have the largest student enrollment, cash collection and net revenues in the third and fourth quarters. We generally generate less tuition fees in the first quarter of each year due to the Chinese New Year holiday. Our expenses, however, vary significantly and do not necessarily correspond to changes in our student enrollment and net revenues. We make investments in marketing and promotion, instructor recruitment and training and course development throughout the year. We expect quarterly fluctuations in our net revenues and results of operations to continue. These fluctuations could result in volatility and adversely affect the price of our ADSs. As our net revenues grow, these seasonal fluctuations may become more pronounced.

Higher labor costs and inflation in China may adversely affect our business and our profitability.

Labor costs in China have risen in recent years. We employed 6,2579,582 employees in China as of December 31, 2016.2017. The increases in labor cost may erode our profitability and materially harm our business, financial condition and results of operations. In addition, PRC government have promulgated some new laws and regulations to enhance labor protection in recent years, such as the Labor Contract Law and the Social Insurance Law, which are also expected to cause our labor costs to increase. As the interpretation and implementation of these new laws and regulations are still evolving, our employment practice may not be at all times be deemed in compliance with the new laws and regulations. If we are subject to severe penalties or incur significant liabilities in connection with labor disputes or investigation, our business and profitability may be adversely affected.

Although we have not in the past been materially affected by inflation since our inception, we can provide no assurance that we will not be affected in the future by higher rates of inflation in China.

We have granted share-based awards and may grant more share-based awards in the future, which may materially reduce our net income.

We adopted a share plan in 2008, or the 2008 Plan, that permits granting of options to purchase our ordinary shares, restricted shares (or share appreciation rights or other similar awards) and rights to purchase restricted shares. Under the 2008 Plan, the maximum aggregate number of ordinary shares that may be issued pursuant to all awards under our share plan is 8,184,990 shares. In February 2014, we adopted a 2014 share incentive plan, or the 2014 Plan. Pursuant to the 2014 Plan, we may issue options, restricted shares and restricted share units to our qualified employees, directors and consultants on a regular basis. The maximum aggregate number of shares which may be issued pursuant to all awards under the 2014 Plan, or the Award Pool, is 1,833,696, provided that the shares reserved in the Award Pool shall be increased on the first day of each calendar year, commencing with January 1, 2015, if the unissued shares reserved in the Award Pool on such day account for less than 2% of the total number of shares issued and outstanding on a fully-diluted basis on December 31 of the immediately preceding calendar year, as a result of which increase the shares unissued and reserved in the Award Pool immediately after each such increase shall equal 2% of the total number of shares issued and outstanding on a fully-diluted basis on December 31 of the immediately preceding calendar year. As a result of grants and potential future grants under the 2008 Plan and the 2014 Plan, we have incurred and will continue to incur share-based compensation expenses. As of December 31, 2016,2017, the unrecognized compensation cost related to unvested options and non-vested shares amounted to RMB71.3RMB59.3 million and RMB0.2RMB6.8 million, respectively, which will be recognized over a weighted average period of approximately 2.181.72 years and 0.25 year.7.46 years. Expenses associated with share-based compensation awards granted under our share plan may materially reduce our future net income. However, if we limit the size of grants under our share plan to minimize share-based compensation expenses, we may not be able to attract or retain key personnel.

Any natural catastrophes, severe weather conditions, health epidemics and other extraordinary events could severely disrupt our business operations.

The occurrence of natural catastrophes such as earthquakes, floods, typhoons, tsunamis or any acts of terrorism may result in significant property damages as well as loss of revenues due to interruptions in our business operations. Health epidemics such as outbreaks of Zika, Ebola, avian influenza, severe acute respiratory syndrome (SARS) or the influenza A (H1N1), and severe weather conditions such as snow storm and hazardous air pollution, as well as the government measures adopted in response to these events, could require the temporary closure of our learning centers.

Furthermore, our ability to broadcast live lectures and provide our education services throughTTS orTMOOC.cn depends on the continuing operation of our technology system, which is vulnerable to damage or interruption from natural catastrophes and other extraordinary events. Our disaster recovery planning cannot account for every conceivable possibility. Any damage to or failure of our technology system could result in interruptions in our services, and our brand could be damaged if students believe our systems are unreliable. Such disruptions could severely interfere with our business operations and adversely affect our results of operations.

Risks Relating to Our Corporate Structure

If the PRC government finds that the agreements that establish the structure for holding our ICP license do not comply with applicable PRC laws and regulations, we could be subject to severe penalties.

Prior to 2012, we conducted a substantial portion of our operations through our consolidated VIEs and their subsidiaries and schools. On January 30, 2012, thePRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective, which listed professional education service as an industry for which foreign investments are “encouraged” by the government. On April 10, 2015, the newPRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective, which listed non-accredited professional education service as an industry for which foreign investments are “encouraged” by the government. On July 28, 2017, the newPRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective, which listed non-accredited professional education service as an industry for which foreign investments are “encouraged” by the government. In light of such change of law, starting from the second half of 2012, we began to transfer the operations, including related assets and liabilities, of our consolidated VIEs to Tarena TechTechnologies Inc. (Tarena Tech) and its subsidiaries and schools. All of our learning center operations of VIEs had been transferred to Tarena Tech and its subsidiaries and schools. In December 2016, we would up Shanghai Tarena, one of our VIEs. Pursuant to theProvisions on Administration of Foreign Invested Telecommunications Enterprises promulgated by the State Council on December 11, 2001 and amended on September 10, 2008, the ultimate foreign equity ownership in a value-added telecommunications services provider may not exceed 50%. Moreover, for a foreign investor to acquire any equity interest in a value-added telecommunication business in China, it must satisfy a number of stringent performance and operational experience requirements, including demonstrating good track records and experience in operating value-added telecommunication business overseas. Foreign investors that meet these requirements must obtain approvals from the MIIT and the Ministry of Commerce, or the MOFCOM, or their authorized local counterparts, which retain considerable discretion in granting approvals. Pursuant to publicly available information, the PRC government has issued telecommunications business operating licenses to only a limited number of foreign investedforeign-invested companies, all of which are Sino-foreign joint ventures engaging in the value-added telecommunication business. Although theGuidance Catalog of Industries for Foreign Investment amended in 20152017 and Circular 196 promulgated by MIIT in June 2015 allows a foreign investor to own up to 100% of the total equity interest in an E-Commerce business, we have not engaged in any E-Commerce business. Due to the foreign ownership restriction on Internet content and other value-added telecommunication services, we operate ourTMOOC.cn andwww.it211.com.cnwebsite through our VIE, Beijing Tarena. Beijing Tarena has added ourTMOOC.cn andwww.it211.com.cn website under the ICP license held by Beijing Tarena. Beijing Tarena is 70% owned by Mr. Shaoyun Han, our founder, chairman and chief executive officer, and 30% owned by Mr. Jianguang Li, our director. Mr. Han and Mr. Li are both PRC citizens. We entered into a series of contractual arrangements with Beijing Tarena and its shareholders, which enable us to:

Because of these contractual arrangements, we are the primary beneficiary of Beijing Tarena and consolidate its financial results in our consolidated financial statements in accordance with U.S. GAAP. For a detailed discussion of these contractual arrangements, see “Item 4. Information on the Company—C. Organizational Structure.”

Han Kun Law Offices, our PRC legal counsel, is of the opinion that (i) the ownership structure of Beijing Tarena and Tarena Tech will not result in any violation of PRC laws or regulations currently in effect; and (ii) the contractual arrangements among Tarena Tech, Beijing Tarena and its shareholders governed by PRC law are valid, binding and enforceable, and will not result in any violation of PRC laws or regulations currently in effect. There are, however, substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations concerning foreign investment in the PRC, and their application to and effect on the legality, binding effect and enforceability of the contractual arrangements. In particular, we cannot rule out the possibility that PRC regulatory authorities, courts or arbitral tribunals may in the future adopt a different or contrary interpretation or take a view that is inconsistent with the opinion of our PRC legal counsel. It is uncertain whether any new PRC laws or regulations relating to VIE will be adopted or if adopted, what they would provide. In or around September 2011, various media sources reported that the China Securities Regulatory Commission, or the CSRC, had prepared a report proposing regulating the use of VIE structures, such as ours, in industries subject to foreign investment restrictions in China and overseas listings by China-based companies. However, it is unclear whether the CSRC officially issued or submitted such a report to a higher level government authority or what such report provides, or whether any new PRC laws or regulations relating to the VIE structures will be adopted or if adopted, what they would provide. In January 2015, the MOFCOM published a discussion draft of the proposedForeign Investment Lawfor public review and comments. Among other things, the draftForeign Investment Law expands the definition of foreign investment and introduces the principle of “actual control” in determining whether a company is considered a foreign-invested enterprise, or an FIE. Under the draft Foreign Investment Law, variable interest entities would also be deemed as FIEs, if they are ultimately “controlled” by foreign investors, and be subject to restrictions on foreign investments. However, the draft law has not taken a position on what actions will be taken with respect to existing companies with the “variable interest entity” structure, whether or not these companies are controlled by Chinese parties. It is uncertain when the draft would be signed into law and whether the final version would have any substantial changes from the draft. See “Item 4. Information on the Company—B. Business Overview—Government Regulations—Regulations on Value–Added Telecommunications Services—The Discussion Draft PRC Foreign Investment Law” and “—Risks Relating to Doing Business in China—Substantial uncertainties exist with respect to the enactment timetable, interpretation and implementation of draft PRC Foreign Investment Law and how it may impact the viability of our current corporate structure, corporate governance and business operations.”

If we or Beijing Tarena is found to be in violation of any existing or future PRC laws or regulations, or such arrangement is determined as illegal and invalid by the PRC court, arbitral tribunal or regulatory authorities, or fail to obtain, maintain or renew any of the required permits or approvals, the relevant PRC regulatory authorities would have broad discretion to take action in dealing with such violations or failures, including:

We launched ourTMOOC.cn online learning platform in March 2015 to cover a broader customer base.TMOOC.cn features sample lecture videos and class materials covering our course subjects. We offer our part-time class students the opportunity to complete a portion of lessons online usingTMOOC.cn.TMOOC.cn is also important for our marketing efforts. Therefore, the imposition of any of these penalties could result in a material and adverse effect on our ability to provide online education services and conduct our marketing and promotional activities throughTMOOC.cn. Beijing Tarena has added ourTMOOC.cn website under its ICP license. However, we cannot guarantee that Beijing Tarena will be successful in applying for the ICP license annual inspection. If we fail to go through the ICP annual inspection, our continued operation ofTMOOC.cn may subject us to penalties, including confiscation of illegal income and fines, and we may be ordered to shut down ourTMOOC.cn website.

If the relevant PRC authorities determine that we can no longer own and operate certain of our learning centers through our PRC subsidiaries, we may need to restructure the ownership and operation of these learning centers (including possibly transferring these learning centers to our consolidated VIE), our business may be disrupted and we may be exposed to increased risks associated with the contractual arrangements relating to our consolidated VIE.

Prior to 2012, we operated a substantial portion of our learning centers through our consolidated VIE and their subsidiaries and schools. After thePRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective on January 30, 2012 and as amended on April 10, 2015 and further amended on June 28, 2017, non-accredited foreign investment in professional education services is now “encouraged” in China and there is no limitation with respect to maximum percentage of foreign ownership in a company conducting business in this area.

In light of such change of law, starting from the second half of 2012, we began to transfer the operations, including related assets and liabilities, of our consolidated VIEs to our wholly-owned subsidiary, Tarena Tech, and its subsidiaries. All of our learning center operations of VIEs had been transferred to Tarena Tech and its subsidiaries and schools. As of December 31, 2016,2017, we operated 4964 of our learning centers through private schools owned by subsidiaries of Tarena Tech. These 4964 learning centers in the aggregate accounted for 31.6%37.1% of our total student enrollments in 2016.2017.

However, there are still uncertainties under current PRC laws as to whether a wholly foreign ownedforeign-owned enterprise (such as Tarena Tech) is allowed to indirectly invest in and own private schools through its PRC subsidiaries. On the one hand, thePRC Catalogue for the Guidance of Foreign Investment Industries (Amended) encourages and permit 100% foreign ownership of non-accredited professional training business in China and theLaw for Promoting Private Education Law does not expressly prohibit a subsidiary of a foreign-invested enterprise from investing in private schools. On the other hand, according to theLaw for Promoting Private Education Law, Chinese-foreign cooperation in operating schools is specifically governed by theRegulations on Operating Chinese-foreign Schools and its implementing rules, which requires specific approvals from those governmental authorities in charge of either human resources and social security or education and requires any foreign party to such Chinese-foreign cooperation in operating schools to be an educational institution with relevant experience in providing educational services outside of China. In addition, theRegulations on Operating Chinese-foreign Schools prohibits foreign institutions or individuals from independently establishing schools which provide educational services mainly for Chinese citizens in China. In practice, different local authorities have different views and administrative policies on whether foreign institutions or individuals are permitted to use their direct or indirect wholly-owned subsidiary incorporated in China to establish a school under the Law for Promoting Private Education Law without violating theRegulations on Operating Chinese-foreign Schools. 24Twenty-five private schools sponsored by our wholly-owned subsidiaries in China have obtained private school operating permits, and based on the results of oral inquiries with the relevant governmental authorities of human resources and social security or education, we believe that the relevant government authorities have not challenged and are unlikely to challenge the ownership structure of our schools. However, if the relevant PRC government authorities determine in the future that we can no longer own and operate our schools and their related learning centers through our PRC subsidiaries, which are considered ineligible to act as sponsors of private schools, we may need to transfer these schools and the related learning centers to our consolidated VIE, which may severely disrupt our business and expose us to increased risks associated with the contractual arrangements relating to our consolidated VIE. See “—Risks Relating to Our Corporate Structure.” If we fail to restructure the ownership and operation of these schools or otherwise accommodate requests from the relevant PRC human resources and social security or education regulatory authorities in a timely manner or to their satisfaction, we may be subject to fines, the suspension or ceasing of our operations or other penalties, which may materially and adversely affect our business and results of operations.

Any failure by Beijing Tarena or its shareholders to perform their obligations under our contractual arrangements with them would have an adverse effect on our business.

If Beijing Tarena or its shareholders fail to perform their obligations under their contractual arrangements with us, we may have to incur substantial costs and expend additional resources to enforce such arrangements. We may also have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief, and claiming damages, which we cannot assure you will be effective. For example, if the shareholders of Beijing Tarena were to refuse to transfer their equity interest in Beijing Tarena to us or our designee if we exercise the exclusive option agreements pursuant to these contractual arrangements, or if they were otherwise to act in bad faith toward us, then we may have to take legal actions to compel them to perform their contractual obligations.

All the agreements under our contractual arrangements are governed by PRC law and provide for the resolution of disputes through arbitration in China. 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 system in the PRC is not as developed as in some other jurisdictions, such as the United States. As a result, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements. Under PRC law, if the losing parties fail to carry out the arbitration awards within a prescribed time limit, the prevailing parties may only enforce the arbitration awards in PRC courts through arbitration award recognition proceedings, which would require additional expenses and delay. In the event we are unable to enforce these contractual arrangements, we may not be able to exert effective financial control over Beijing Tarena, and our ability to conduct our business may be negatively affected.

If we had direct ownership of Beijing Tarena, we would be able to exercise our rights as a shareholder to effect changes in the board of directors of Beijing Tarena, which in turn could effect changes, subject to any applicable fiduciary obligations, at the management level. However, under the current contractual arrangements, we rely on the performance by Beijing Tarena and its shareholders of their obligations under the contracts to exercise control over Beijing Tarena. Therefore, our contractual arrangements with Beijing Tarena may not be as effective in ensuring our control over the relevant portion of our business operations as direct ownership would be.

The shareholders of Beijing Tarena may have potential conflicts of interest with us, which may materially and adversely affect our business and financial condition.

We have designated individuals who are PRC nationals to be the shareholders of Beijing Tarena. The equity interests of Beijing Tarena are held by Mr. Shaoyun Han and Mr. Jianguang Li. The interests of these individuals as the shareholders of Beijing Tarena may differ from the interests of our company as a whole. These shareholders may breach, or cause Beijing Tarena to breach, or refuse to renew, the existing contractual arrangements we have with them and Beijing Tarena, which would have a material and adverse effect on our ability to effectively control Beijing Tarena. We cannot assure you that when conflicts of interest arise, any or all of these shareholders will act in the best interests of our company or such conflicts will be resolved in our favor.

Currently, we do not have any arrangements to address potential conflicts of interest between these shareholders and our company, except that we could exercise our purchase option under the purchase option agreement with these shareholders to request him to transfer all of his equity ownership in Beijing Tarena to a PRC entity or individual designated by us. We rely on Mr. Shaoyun Han and Mr. Jianguang Li, who are both our directors and who owe a fiduciary duty to our company, to comply with the terms and conditions of the contractual arrangements. Such fiduciary duty requires directors to act in good faith and in the best interests of the company and not to use their positions for personal gains. If we cannot resolve any conflict of interest or dispute between us and the shareholders of Beijing Tarena, we would have to rely on legal proceedings, which could result in disruption of our business and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

Our contractual arrangements with our consolidated VIE may be subject to scrutiny by the PRC tax authorities, and a finding that we owe additional taxes could substantially reduce our consolidated net income and the value of your investment.

Under PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities. We could face material and adverse tax consequences if the PRC tax authorities determine that the contractual arrangements among Tarena Tech and our consolidated VIE did not represent an arm’s-lengtharms-length price and adjust our consolidated VIE’ income in the form of a transfer pricing adjustment. A transfer pricing adjustment could, among other things, result in a reduction, for PRC tax purposes, of expense deductions recorded by our consolidated VIE, which could in turn increase their tax liabilities without reducing our tax liabilities. In addition, the PRC tax authorities may impose late payment fees and other penalties to our consolidated VIE for under-paid taxes. Our consolidated net income may be materially and adversely affected if our tax liabilities increase or if we are found to be subject to late payment fees or other penalties.

If Beijing Tarena becomes the subject of a bankruptcy or liquidation proceeding, we may lose the ability to use and enjoy its assets, which could materially and adversely affect our business.

Due to foreign ownership restrictions in the online value-added telecommunications business, we hold our ICP license through contractual arrangements with Beijing Tarena as well as its shareholders. As part of these arrangements, Beijing Tarena holds assets that are important to the operation of our business, including the domain name and ICP license for ourwww.it211.com.cn andTMOOC.cn website.websites.

We do not have priority pledges and liens against Beijing Tarena’s assets. As a contractual and property right matter, this lack of priority pledges and liens has remote risks. If Beijing Tarena undergoes an involuntary liquidation proceeding, third-party creditors may claim rights to some or all of its assets and we may not have priority against such third-party creditors on Beijing Tarena’s assets. If Beijing Tarena liquidates, we may take part in the liquidation procedures as a general creditor under the PRC Enterprise Bankruptcy Law and recover any outstanding liabilities owed by Beijing Tarena to Tarena Tech under the applicable service agreements. To ameliorate the risks of an involuntary liquidation proceeding initiated by a third-party creditor, we closely monitor the operations and finances of Beijing Tarena through carefully designed budgetary and internal controls to ensure that Beijing Tarena is well capitalized and is highly unlikely to trigger any third party monetary claims in excess of its assets and cash resources. Furthermore, Tarena Tech has the ability, if necessary, to provide financial support to Beijing Tarena to prevent such an involuntary liquidation.

If the shareholders of Beijing Tarena were to attempt to voluntarily dissolve or liquidate Beijing Tarena without obtaining our prior consent, we could effectively prevent such unauthorized voluntary liquidation by exercising our right to request Beijing Tarena’s shareholders to transfer all of their equity ownership interest to a PRC entity or individual designated by us in accordance with the exclusive option agreements with the shareholders of Beijing Tarena. In the event that the shareholders of Beijing Tarena initiatesinitiate a voluntary liquidation proceeding without our authorization or attempts to distribute the retained earnings or assets of Beijing Tarena without our prior consent, we may need to resort to legal proceedings to enforce the terms of the contractual agreements. Any such legal proceeding may be costly and may divert our management’s time and attention away from the operation of our business, and the outcome of such legal proceeding would be uncertain. The uncertainties in legal proceedings to enforce the terms of the contractual agreements are mainly caused by PRC laws that prohibit domestic companies holding ICP licenses from assisting foreign investors in conducting value-added telecommunications business in China. Under the MIIT Circular, a domestic company that holds an ICP license is prohibited from leasing, transferring or selling the license to foreign investors in any form, and from providing any assistance, including providing resources, sites or facilities, to foreign investors that conduct value-added telecommunications business illegally in China.

If the custodians or authorized users of our controlling non-tangible assets, including chops and seals, fail to fulfill their responsibilities, or misappropriate or misuse these assets, our business and operations could be materially and adversely affected.

In China, legal documents for corporate transactions, including agreements and contracts such as the leases and sales contracts that our business relies on, are typically executed using the chop or seal of the signing entity or with the signature of a legal representative whose designation is registered and filed with the relevant local branch of the State Administration for Industry and Commerce, or the SAIC. We generally execute legal documents by affixing chops or seals, rather than having the designated legal representatives sign the documents.

We have three major types of chops—corporate chops, contract chops and finance chops. We use corporate chops generally for documents to be submitted to government agencies, such as applications for changing business scope, directors or company name, and for legal letters. We use contract chops for executing leases and commercial contracts. We use finance chops generally for making and collecting payments, including but not limited to issuing invoices. Use of corporate chops and contract chops must be approved by our legal department and administrative department, and use of finance chops must be approved by our finance department. The chops of our subsidiaries and our consolidated VIE are generally held by the relevant entities so that documents can be executed locally. Although we usually utilize chops to execute contracts, the registered legal representatives of our PRC subsidiaries and our consolidated VIE have the apparent authority to enter into contracts on behalf of such entities without chops, unless such contracts set forth otherwise. All designated legal representatives of our PRC subsidiaries and our consolidated VIE have signed employment agreements with us under which they agree to abide by duties they owe to us.

In order to maintain the physical security of our chops, we generally store them in secured locations accessible only to the department heads of the legal, administrative or finance departments. Our designated legal representatives generally do not have access to the chops. Although we monitor our employees, including the designated legal representatives of our PRC subsidiaries and our consolidated VIE, the procedures may not be sufficient to prevent all instances of abuse or negligence. There is a risk that our employees or designated legal representatives could abuse their authority, for example, by binding the relevant subsidiary or consolidated VIE with contracts against our interests, as we would be obligated to honor these contracts if the other contracting party acts in good faith in reliance on the apparent authority of our chops or signatures of our legal representatives. If any designated legal representative obtains control of the chop in an effort to obtain control over the relevant entity, we would need to have a shareholder or board resolution to designate a new legal representative and to take legal action to seek the return of the chop, apply for a new chop with the relevant authorities, or otherwise seek legal remedies for the legal representative’s misconduct. If any of the designated legal representatives obtains and misuses or misappropriates our chops and seals or other controlling intangible assets for whatever reason, we could experience disruption to our normal business operations. We may have to take corporate or legal action, which could involve significant time and resources to resolve while distracting management from our operations.

Risks Relating to Doing Business in China

Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.

The PRC legal system is based on written statutes. Unlike common law systems, it is a system in which legal cases have limited value as precedents. In the late 1970s, the PRC government began to promulgate a comprehensive system of laws and regulations governing economic matters. The overall effect of legislation over the past three decades has significantly increased the protections afforded to various forms of foreign or private-sector investment in China. Our PRC subsidiaries are subject to various PRC laws and regulations generally applicable to companies in China. However, since these laws and regulations are relatively new and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties.

From time to time, we may have to resort to administrative and court proceedings to enforce our legal rights. However, since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. Furthermore, the PRC legal system is based in part on government policies and internal rules (some of which are not published in a timely manner or at all) some of which may have retroactive effect. As a result, we may not be aware of our violation of these policies and rules until some time after the violation. Such uncertainties, including uncertainty over the scope and effect of our contractual, property (including intellectual property) and procedural rights, and any failure to respond to changes in the regulatory environment in China could materially and adversely affect our business and impede our ability to continue our operations.

Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and operations.

All of our business operations are conducted in China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally and by continued economic growth in China as a whole.

China’s 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 PRC government has implemented measures since the late 1970s emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the PRC government. In addition, the PRC government continues to play a significant role in regulating industry development by imposing industrial policies. The PRC government also exercises significant control over the PRC economic growth through allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, and providing preferential treatment to particular industries or companies.

While China’s economy has experienced significant growth over the past decades, growth has been uneven, both geographically and among various sectors of the economy, and the rate of growth has been slowing. Some of the government measures may benefit the overall Chinese economy, but may have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations. Any stimulus measures designed to boost the Chinese economy may contribute to higher inflation, which could adversely affect our results of operations and financial condition.

We may be subject to significant limitations on our ability to operate private schools, or otherwise be materially and adversely affected by changes in PRC laws governing private education providers.

Under theLaw for Promoting Private Education and theImplementation Rules for The Law for Promoting Private Education, a private school may elect to be a school that does not require reasonable returns or a school that requires reasonable returns. At the end of each fiscal year, every private school is required to allocate a certain amount to its development fund for the construction or maintenance of the school or procurement or upgrade of educational equipment. In the case of a private school that requires reasonable returns, this amount shall be no less than 25% of annual net income of the school, while in the case of a private school that does not require reasonable returns, this amount shall be equivalent to no less than 25% of the annual increase in the net assets of the school, if any. A private school that requires reasonable returns must publicly disclose such election and additional information requiredAffected under the regulations. A private school shall consider factors such as the school’s tuition, ratio of the funds used for education-related activities to the course fees collected, admission standards and educational quality when determining the percentage of the school’s net income that would be distributed to the investors as reasonable returns. However, none of the current PRC laws and regulations provides a formula or guidelines for determining “reasonable returns.” In addition, the amendment of theLaw for Promoting Private Education released on November 7, 2016, which will become effective on September 1, 2017, allows for-profit private schools to obtain returns, which will be further regulated by the PRC corporate law and other relevant laws and regulations.

As of December 31, 2016, we had five schools registered as schools requiring reasonable returns, while 20 schools are registered as schools not requiring reasonable returns. Unlike typical schools which grant diplomas to students upon graduation, we provide professional education and do not grant any diploma to our students. However, the current PRC laws and regulations governing private education may be amended or replaced by new laws and regulations that (i) impose significant limitations on the ability of our schools to operate their business, charge course fees or make payments to related parties for services, (ii) specify the formula for calculating “reasonable returns,” or (iii) change the tax treatment policies applicable to private schools. We cannot predict the timing and effects of any such amendments or new laws and regulations. Changes in PRC laws and regulations governing private education could materially and adversely affect our business prospects and results of operations. For example, if the PRC government imposes additional restrictions on private schools’ ability to operate their business or restricts private schools from making payments to related parties for services, our ability to receive service fees from our schools may be limited.

Under the PRC Enterprise Income Tax Law, we may be classified as a PRC “resident enterprise” for PRC enterprise income tax purposes. Such classification would likely result in unfavorable tax consequences to us and our non-PRC shareholders and have a material adverse effect on our results of operations and the value of your investment.

Under the PRCEnterprise Income Tax Law, or the EIT Law, that became effective on January 1, 2008, an enterprise established outside the PRC with “de facto management bodies” within the PRC is considered a PRC “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. Under the Implementation Rules to the EIT Law, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise. In addition, a circular, known as Circular 82, issued in April 2009, as amended in January 2014, by the State Administration of Taxation, or the SAT, specifies that certain offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups will be classified as PRC resident enterprises if the following are located or resident in the PRC: senior management personnel and departments that are responsible for daily production, operation and management; financial and personnel decision making bodies; key properties, accounting books, company seal, and minutes of board meetings and shareholders’ meetings; and half or more of the senior management or directors having voting rights. Circular 82 also clarified that dividends and other income paid by such “resident enterprises” will be considered to be PRC source income, subject to PRC withholding tax, currently at a rate of 10%, when recognized by shareholders that are non-PRC resident enterprises. Further to Circular 82, the SAT issued a bulletin, known as Bulletin 45, which took effect on September 1, 2011, to provide more guidance on the implementation of Circular 82 and clarify the reporting and filing obligations of such “Chinese-controlled offshore-incorporated resident enterprises.” Bulletin 45 provides procedures and administrative details for the determination of PRC resident enterprise status and administration on post-determination matters. Although both Circular 82 and Bulletin 45 only apply to offshore enterprises controlled by PRC enterprises or PRC enterprise groups, not those controlled by PRC individuals or foreign individuals like us, the determining criteria set forth in Circular 82 and Bulletin 45 may reflect the SAT’s general position on how the “de facto management body” test should be applied in determining the tax resident enterprise status of offshore enterprises, regardless of whether they are controlled by PRC enterprises, PRC enterprise groups or by PRC or foreign individuals.

We do not believe that Tarena International, Inc. meets all of the conditions above and thus we do not believe that Tarena International, Inc. is a PRC resident enterprise, despite the fact that all of the members of our management team as well as the management team of our offshore holding company are located in China. However, if the PRC tax authorities determine that Tarena International, Inc. is a PRC resident enterprise for PRC enterprise income tax purposes, a number of unfavorable PRC tax consequences could follow. First, we will be subject to the uniform 25% enterprise income tax on our world-wideworldwide income, which could materially reduce our net income. In addition, we will also be subject to PRC enterprise income tax reporting obligations. Second, although dividends paid by one PRC tax resident to another PRC tax resident should qualify as “tax-exempt income” under the EIT Law, we cannot assure you that such dividends will not be subject to a 10% withholding tax, as the PRC foreign exchange control authorities, which enforce the withholding tax on dividends, and the PRC tax authorities have not yet issued guidance with respect to the processing of outbound remittances to entities that are not controlled by any PRC enterprise or enterprise group and treated as resident enterprises for PRC enterprise income tax purposes.

Finally, dividends we pay to our non-PRC enterprise shareholders and gains derived by our non-PRC shareholders from the sale of our shares may bemaybe become subject to a 10% PRC withholding tax. In addition, future guidance may extend the withholding tax to dividends we pay to our non-PRC individual shareholders and gains derived by such shareholders from transferring our shares. In addition to the uncertainty in how the new “resident enterprise” classification could apply, it is also possible that the rules may change in the future, possibly with retroactive effect. If PRC income tax were imposed on gains realized through the transfer of our ADSs or ordinary shares or on dividends paid to our non-resident investors, the value of the investment in our ADSs or ordinary shares may be materially and adversely affected. Furthermore, our ADS holders whose jurisdictions of residence have tax treaties or arrangements with China may not qualify for benefits under such tax treaties or arrangements.

We face uncertainty regarding the PRC tax reporting obligations and consequences for certain indirect transfers of our operating company’s equity interests. Enhanced scrutiny over acquisition transactions by the PRC tax authorities may have a negative impact on potential acquisitions we may pursue in the future.

In connection with the EIT Law, the Ministry of Finance and the SAT jointly issued a Circular 59 in April 2009, and the SAT issued a Circular 698 in December 2009. Both Circular 59 and Circular 698 became effective retroactively on January 1, 2008.

According to Circular 698, where a non-resident enterprise transfers the equity interests of a PRC “resident enterprise” indirectly by disposition of the equity interests of an overseas holding company, or an Indirect Transfer, and the overseas holding company is located in a tax jurisdiction that: (i) has an effective tax rate less than 12.5% or (ii) does not impose tax on foreign income of its residents, the non-resident enterprise, being the transferor, must report to the relevant tax authority of the PRC “resident enterprise” this Indirect Transfer. Using a “substance over form” principle, the PRC tax authority may disregard the existence of the overseas holding company if it lacks a reasonable commercial purpose and was established for the purpose of reducing, avoiding or deferring PRC tax. As a result, gains derived from such Indirect Transfer may be subject to PRC withholding tax at a rate of up to 10%. Circular 698 also provides that, where a non-PRC resident enterprise transfers its equity interests in a PRC “resident enterprise” to its related parties at a price lower than the fair market value, the relevant tax authority has the power to make a reasonable adjustment to the taxable income of the transaction. In addition, the PRC “resident enterprise” is supposed to provide necessary assistance to support the enforcement of Circular 698.

On February 3, 2015, the SAT issued a Public Notice [2015] No.7, or Public Notice 7, to supersede the existing tax rules in relation to the Indirect Transfer while the other provisions ofunder Circular 698 remain in force.698. Under Public Notice 7, introducedwhere a new tax regime that is significantly different from that under Circular 698. Public Notice extend its tax jurisdiction to capture not only Indirect Transfer as set forth under Circular 698 but also transactions involving transfer of immovable propertynon-resident enterprise conducts an “indirect transfer” by transferring the equity interests in China anda PRC “resident enterprise” or other taxable assets held under the establishment and place, in China of a foreign company through the offshore transfer of a foreign intermediate holding company. Public Notice 7 also addresses the term transferindirectly by disposing of the equity interestinterests in a foreign intermediatean overseas holding company, widely.the non-resident enterprise, being the transferor, may be subject to PRC enterprise income tax, if the indirect transfer is considered to be an abusive use of company structure without reasonable commercial purposes. In addition, Public Notice 7 provides clearerclear criteria than Circular 698 on how to assess reasonable commercial purposes and introduces safe harbor scenarios applicable to internal group restructurings. However, it also brings challenges to both the foreign transferor and transferee of the Indirect Transfer as they have to make self-assessment on whether the transaction should be subject to PRC tax and to file or withhold the PRC tax accordingly. Since Public Notice 7 was recently promulgated and it is unclear how this set of measures, and any future implementation rules thereof, will be interpreted, amended and implemented by the relevant governmental authorities. Where non-resident investors were involved in our private equity financing, if such transactions were determined by the tax authorities to lack reasonable commercial purpose, we and our non-resident investors may become at risk of being taxed under Circular 698 and Public Notice 7 and may be required to expend valuable resources to comply with Circular 698 and Public Notice 7 or to establish that we should not be taxed under Circular 698 and Public Notice 7, which may have a material adverse effect on our financial condition and results of operations or the non-resident investors’ investments in us.

In October 2017, the SAT promulgated the Announcement of the State Administration of Taxation on Matters Concerning Withholding of Income Tax of Non-resident Enterprises at Source, or SAT Circular 37, which provides certain changes to the current withholding regime, repeals and replaces all other provisions under Circular 698 and amends certain provisions in Public Notice 7. For example, SAT Circular 37 requires that the transferor shall declare to the competent tax authority for payment of tax within seven (7) days after the tax payment obligation comes into being if the withholding agent fails to withhold the tax due or withhold the tax due in full. However, according to SAT Circular 37, if the withholding agent fails to withhold and remit the income tax payable, or is unable to perform its obligation in this regard, as long as the non-resident enterprise that earns the income voluntarily declares and pays the tax payable before the tax authority orders it to do so within required time limits, it shall be deemed that such enterprise has paid the tax in time.

By promulgating and implementing these circulars, the PRC tax authorities have enhanced their scrutiny over the direct or indirect transfer of equity interests in a PRC resident enterprise by a non-resident enterprise. The PRC tax authorities have the discretion under Circular 59, Circular 698 and Public Notice 7 and SAT Circular 37 to make adjustments to the taxable capital gains based on the difference between the fair value of the equity interests transferred and the cost of investment. Although we currently have no confirmed plans to pursue any acquisitions in China or elsewhere in the world, we may pursue acquisitions in the future that may involve complex corporate structures. If we are considered a non-resident enterprise under the EIT Law and if the PRC tax authorities make adjustments under Circular 59 or Circular 698 and Public Notice 7 or SAT Circular 37, our income tax costs associated with such potential acquisitions will be increased, which may have an adverse effect on our financial condition and results of operations.

In addition, the State Administration of Taxation promulgated Administrative Measures on the General Anti-Avoidance Rule (Trial), or GAAR Measures, on December 12, 2014, which shows the authority’s intention to fight against tax avoidance scheme that is adopted to obtain unwarranted tax benefit without reasonable commercial purpose. A press release, made by the State Administration of Taxation to clarify certain issues relating to the application of the GAAR Measures, stated that the GAAR Measures may be applicable if any general tax-avoidance scheme exists in the offshore indirect transfer of equity interests. Since GAAR Measures was recently promulgated and it is unclear how this set of measures, and any future implementation rules thereof, will be interpreted, amended and implemented by the relevant governmental authorities, we cannot predict how these regulations will affect our business operation, future acquisitions or strategy.

We face risks and uncertainties with respect to the licensing requirement for Internet audio-video programs and human resources intermediary service.

In December 2007, the State Administration of Press Publication Radio Film and Television, or SAPPRFT, the predecessor of Administration of Radio and Television newly established in April 2018, and the Ministry of Industry and Information Technology, or MIIT, issued theAdministrative Measures Regarding Internet Audio-Video Program Services, or theInternet Audio-Video Program Measures, which became effective on January 31, 2008. Among other things, the Internet Audio-Video Program Measures stipulate that no entities or individuals may provide Internet audio-video program services without a “License for Disseminating Audio-Video Programs through Information Network” issued by SAPPRFT or its local bureaus or completing the relevant registration with SAPPRFT or its local bureaus, and only entities wholly owned or controlled by the PRC government may engage in the production, editing, integration or consolidation, and transmission to the public through the Internet, of audio-video programs, or the provision of audio-video program uploading and transmission services. In February 2008, SAPPRFT and MIIT jointly held a press conference in response to inquiries related to theInternet Audio-Video Program Measures, during which SAPPRFT and MIIT officials indicated that providers of audio-video program services established prior to the promulgation date of theInternet Audio-Video Program Measures that do not have any regulatory non-compliance records can re-register with the relevant government authorities to continue their current business operations. After the conference, the two authorities published a press release that confirmed the above guidelines. There are still significant uncertainties relating to the interpretation and implementation of the Internet Audio-Video Program Measures, in particular, the scope of “Internet Audio-Video Programs.”

Furthermore, on April 1, 2010, SAPPRFT promulgated the Test Implementation of the Tentative Categories of Internet Audio-Visual Program Services, or the Categories, which clarified the scope of Internet audio-video programs services. According to the Categories, there are four categories of Internet audio-visual program services which are further divided into seventeen sub-categories. The third sub-category to the second category covers the making and editing of certain specialized audio-video programs concerning, among other things, educational content, and broadcasting such content to the general public online.

We transmit our audio-video educational programs through our TTS system andTMOOC.cn to enrolled course participants. In addition, we provide audio-video program uploading and transmission services. As a result, we might be subject to the Internet Audio-Video Program Measures. If the governmental authorities determine that our provision of lecture videos on TTS and/orTMOOC.cn falls within the Internet Audio-Video Program Measures, we may not be able to obtain the License for Disseminating Audio-Video Programs through Information Network. If this occurs, we may become subject to significant penalties, fines, legal sanctions or an order to suspend our use of audio-video content, all of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Pursuant to the Provisions on the Administration of Human Resources Markets issued by SAIC in 2001 and as amended in 2005 and 2015, respectively, a human resources service intermediary refers to any entity which provides intermediary services for employers and any potential employees, and no entity may provide such services without a “License for Human Resources Intermediary Resources.” Any internet information service provider which provides intermediary services for employers and any potential employees via internet shall obtain such license. In January 2015, we launched a self-developed job search website called Job Show (www.jobshow.cn), which serves as a dedicated open platform for our students and other job-seeking candidates to connect with corporate employers more effectively. Although we have not entered into any agreement with corporate employers or any job-seeking candidates, we source and list job opportunities from both IT and non-IT employers in China through the website, which may be deemed as a human resources service intermediary. Currently, we have recorded human resources intermediary services in our business license but we have not obtained the “License for Human Resources Intermediary Resources,” and if the relevant PRC government authorities determine that we shall obtain such license for the operation of Job Show and we fail to obtain such license, they may order us to shut down the website and subject us to a fine of RMB10,000 and if there is any illegal income, we may be subject a fine of no more than three times of the illegal income, which shall not exceed RMB30,000.

PRC regulations establish complex approval procedures for some acquisitions of PRC companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China. The transfers of our learning centers from our consolidated VIE to our wholly-owned subsidiaries in China may be subject to such approval procedures, in which case we may need to restructure the ownership and operation of the affected learning centers, and as a result we may be exposed to increased risks associated with the contractual arrangements relating to our consolidated VIE.

Six PRC regulatory agencies promulgated regulations effective in September 2006 that are commonly referred to as the M&A Rules. The M&A Rules. TheM&A Rules establish procedures and requirements that could make some acquisitions of PRC companies by foreign investors more time-consuming and complex, including requirements in some instances that the MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise. In addition, national security review rules issued by the PRC governmental authorities in 2011 require acquisitions by foreign investors of domestic companies engaged in military-related or certain other industries that are crucial to national security to be subject to prior security review. Moreover, theAnti-Monopoly Law requires that the MOFCOM shall be notified in advance of any concentration of undertaking if certain thresholds are triggered. We may expand our business in part by acquiring complementary businesses. Complying with the requirements of theM&A Rules, security review rules and other PRC regulations to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval from the MOFCOM, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share.

In addition, in accordance with theM&A Rules, approval of the MOFCOM is required for acquisitions of PRC domestic enterprises by foreign companies that are established or controlled by PRC domestic companies, enterprises or individuals related to the target PRC domestic enterprises, or “Related Party Acquisitions”, and the parties are not allowed to evade such requirements through investment by foreign investment enterprises in China or other ways. AlthoughM&A Rules have become effective since September 2006, we are not aware of any precedent of approval by the MOFCOM of any Related Party Acquisition conducted by PRC domestic individuals. Starting from the second half of 2012, we began to transfer our operations, including related assets and liabilities, of our consolidated VIEs to our wholly-owned subsidiary, Tarena Tech, and its subsidiaries, either through transferring the companies that operate learning centers or that sponsor the schools, or through changing the schools’ sponsors. All of our learning center operations of VIEs had been transferred to Tarena Tech and its subsidiaries and schools. As Mr. Shaoyun Han is a shareholder of both Tarena and our consolidated VIEs, even though the transfers of the companies, which operated 23 of our learning centers themselves or through schools they established as of December 31, 2016,2017, from our consolidated VIEs to our wholly-owned subsidiaries in China are not “acquisitions by foreign investors of PRC domestic enterprises” under the M&A Rules, and Tarena Tech, our wholly foreign invested enterprise in PRC, was converted into a wholly foreign invested enterprise before the effective date ofM&A Rules, the requirement for an approval from the MOFCOM may still be required for such transfers because of the above anti-evasion clause. Furthermore, it is unclear whether our transfers of the schools which operated 1423 learning centers as of December 31, 2016,2017, which are not enterprises, from subsidiaries of our consolidated VIEs to our wholly-owned subsidiaries, could be regarded as Related Party Transactions under theM&A Rules.Rules. If the MOFCOM determines that our previous transfers of learning centers from our consolidated VIEs to our wholly-owned subsidiaries are Related Party Transactions under the M&A Rules and we fail to obtain the MOFCOM’s approvals on such transfers, the effectiveness of such transfers may be challenged and we may be need to transfer these companies and schools, including the related learning centers, back to our consolidated VIE. Under such circumstances, our business may be disrupted and we may be exposed to increased risks associated with the contractual arrangements relating to our consolidated VIE. See “—Risks Relating to Our Corporate Structure.”

PRC regulations relating to offshore investment activities by PRC residents may limit our PRC subsidiaries’ ability to increase their registered capital or distribute profits to us, limit our ability to inject capital into our PRC subsidiaries, or otherwise expose us to liability and penalties under PRC law.

The PRC State Administration of Foreign Exchange, or the SAFE, has promulgated regulations, including theNotice on Relevant Issues Relating to Domestic Residents’ Investment and Financing and Round-Trip Investment through Special Purpose Vehicles, or SAFE Circular No. 37, effective on July 4, 2014, and its appendixes, that require PRC residents, including PRC institutions and individuals, to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular No. 37 as a “special purpose vehicle.” SAFE Circular No. 37 further requires an amendment to the registration in the event of any significant changes with respect to the special purpose vehicle, such as an increase or decrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event.events. In the event that a PRC shareholder holding interests in a special purpose vehicle fails to fulfill the required SAFE registration, the PRC subsidiaries of that special purpose vehicle may be prohibited from making profit distributions to the offshore parent and from carrying out subsequent cross-border foreign exchange activities, and the special purpose vehicle may be restricted in their ability to contribute additional capital into its PRC subsidiary. Further, failure to comply with the various SAFE registration requirements described above could result in liability under PRC law for foreign exchange evasion, including (i) the requirement by SAFE to return the foreign exchange remitted overseas within a period specified by SAFE, with a fine of up to 30% of the total amount of foreign exchange remitted overseas and deemed to have been evasive and (ii) in circumstances involving serious violations, a fine of no less than 30% of and up to the total amount of remitted foreign exchange deemed evasive. Furthermore, the persons-in-charge and other persons at our PRC subsidiaries who are held directly liable for the violations may be subject to criminal sanctions. On February 28, 2015, SAFE promulgated aNotice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, which became effective on June 1, 2015. In accordance with SAFE Notice 13, entities and individuals are required to apply for foreign exchange registration of foreign direct investment and overseas direct investment, including those required under the SAFE Circular No. 37, with qualified banks, instead of SAFE. The qualified banks, under the supervision of SAFE, directly examine the applications and conduct the registration.

These regulations apply to our direct and indirect shareholders who are PRC residents and may apply to any offshore acquisitions or share transfers that we make in the future if our shares are issued to PRC residents. We have requested PRC residents who we know currently hold direct or indirect interests in our company to make the necessary applications, filings and amendments as required under SAFE Circular No. 37 and other related rules.

To our knowledge, all of our shareholders who are PRC citizens and hold interestinterests in us, have registered with the local SAFE branch and/or qualified banks as required under SAFE Circular No. 37 and SAFE Notice 13. However, in practice, different local SAFE branches and/or qualified banks may have different views and procedures on the application and implementation of SAFE regulations. Therefore, we cannot assure you that they can successfully amend their foreign exchange registrations with the local SAFE branch and/or qualified banks in full compliance with applicable laws. In addition, we may not be informed of the identities of all the PRC residents holding direct 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 any applicable registrations or comply with other requirements required by SAFE Circular No. 37, SAFE Notice 13 or other related rules. A failure by any of our current or future shareholders or beneficial owners who are PRC residents to comply with the SAFE regulations may subject us to fines or other legal sanctions, restrict our cross-border investment activities, limit our PRC subsidiaries’ ability to make distributions or pay dividends or affect our ownership structure, which could adversely affect our business and prospects.

Furthermore, it is unclear how these regulations, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant government authorities. We cannot predict how these regulations will affect our business operations or future strategy. For example, we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our financial condition and results of operations. In addition, if we decide to acquire a PRC domestic company, either we or the owners of such company, as the case may be, may not be able to obtain the necessary approvals or complete the necessary filings and registrations required by the foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

Failure to comply with PRC regulations regarding the registration requirements for employee share ownership plans or share option plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices onIssues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly-Listed Companies, or the Stock Option Rules. Under the Stock Option Rules. Under theStock Option Rules and other relevant rules and regulations, PRC residents who participate in 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 the overseas publicly-listed company or another qualified institution selected by the PRC subsidiary, to conduct the SAFE registration and other procedures with respect to the stock incentive plan on behalf of its participants. The participants must also retain an overseas entrusted institution to handle matters in connection with their exercise of stock options, the purchase and sale of corresponding stocks or interests and fund transfers. In addition, the PRC agent is required to amend the 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 overseas entrusted institution or other material changes. See “Item 4. Information on the Company—B. Business Overview—Government Regulations—Regulations on Stock Incentive Plans.” We and our PRC employees who have been granted share options and restricted share units are subject to these regulations and we have completed the registrations of our stock incentive plans, namely the 2008 Plan and the 2014 Plan, with the local SAFE as required by PRC law. Failure of our PRC share option holders or restricted shareholders to complete their SAFE registrations may subject these PRC residents to fines and legal sanctions and may also limit our ability to contribute additional capital into our PRC subsidiaries, limited our PRC subsidiaries’ ability to distribute dividends to us, or otherwise materially and adversely affect our business.

PRC regulation of direct investment and loans by offshore holding companies to PRC entities and governmental control of currency conversion may delay or limit us from using the proceeds of offshore offerings to make additional capital contributions or loans to our PRC subsidiaries.

Any capital contributions or loans that we, as an offshore entity, make to our PRC subsidiaries are subject to PRC regulations. Under PRC laws and regulations, we are permitted to utilize the proceeds from offshore offerings to fund our existing PRC subsidiaries only through loans or capital contributions or to establish new PRC subsidiaries, subject to applicable government registration and approval requirements. None of our loans to a PRC subsidiary can exceed the difference between its total amount of investment and its registered capital approved under relevant PRC laws, and the loans must be registered with the local branch of SAFE. Our capital contributions to our PRC subsidiaries or establishment of new PRC subsidiaries must be approved by the MOFCOM or its local counterpart. We cannot assure you that we will be able to complete the necessary registration or obtain the necessary approval on a timely basis, or at all. If we fail to complete the necessary registration or obtain the necessary approval, our ability to make loans or equity contributions to our PRC subsidiaries may be negatively affected, which could adversely affect our PRC subsidiaries’ liquidity and their ability to fund their working capital and expansion projects and meet their obligations and commitments.

On March 30, 2015, the SAFE promulgated Circular 19, which expands a pilot reform of the administration of the settlement of the foreign exchange capitals of foreign-invested enterprises nationwide. Circular 19 came into force replacing both previous SAFE Circular 142 and SAFE Circular 36 on June 1, 2015. Circular 19 allows all foreign-invested enterprises established in the PRC to use their foreign exchange capitals to make equity investmentinvestments and removes certain other restrictions provided under Circular 142 for these enterprises. However, Circular 19 continues to prohibit foreign-invested enterprises from, among other things, using the Renminbi fund converted from its foreign exchange capitals for expenditure beyond its business scope, and providing entrusted loans or repaying loans between non-financial enterprises. The business scopes of Tarena Tech include research and development of computer software, hardware, internet technology and products and telecommunications technology, transfer of proprietary technologies, information technology consulting, technical services, computer technology training, sales of self-developed products and franchise business operations. The business scopes of Tarena Software Technology (Hangzhou) Co., Ltd., or Tarena Hangzhou, include technology development, technology consulting, technical services, computer software and hardware, network technology, telecommunication technology, services, non-certification computer technology training for adults (excluding business subject to pre-approvals), wholesale and retail of computer software and hardware and telecommunication equipment (excluding equipment subject to national controls and other special controls). Tarena Tech and Tarena Hangzhou may only use Renminbi converted from foreign exchange capital contribution for activities within their respective approved business scope. Therefore, we may not use such Renminbi funds converted to make equity investments in the PRC through our PRC subsidiaries. In addition, the use of such Renminbi capital may not be altered without SAFE approval, and such Renminbi capital may not in any case be used to repay Renminbi loans if the proceeds of such loans have not been used. Violations of SAFE Circular 19 could result in severe monetary or other penalties.

SAFE also promulgated a SAFE Circular 45 in November 2011, which, among other things, restricts a foreign-invested enterprise from using RMB converted from its registered capital to provide entrusted loans or repay loans between non-financial enterprises. Those circulars may significantly limit our ability to use Renminbi converted from the net proceeds of offshore offerings to fund the establishment of new PRC subsidiaries by Tarena Tech and Tarena Hangzhou to invest in or acquire any other PRC companies, or to establish new PRC consolidated affiliated entities.

Our PRC subsidiaries are subject to restrictions on paying dividends or making other payments to us, which may restrict our ability to satisfy our liquidity requirements.

We are a holding company incorporated in the Cayman Islands. We may need dividends and other distributions on equity from our PRC subsidiaries to satisfy our liquidity requirements. Current PRC regulations permit our PRC subsidiaries to pay dividends to us only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, our PRC subsidiaries are required to set aside at least 10% of their respective accumulated profits each year, if any, to fund certain reserve funds until the total amount set aside reaches 50% of their respective registered capital. Our PRC subsidiaries may also allocate a portion of its after-tax profits based on PRC accounting standards to employee welfare and bonus funds at their discretion. These reserves are not distributable as cash dividends. Furthermore, if our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments to us. Any limitation on the ability of our subsidiaries to distribute dividends to us or may restrict our ability to satisfy our liquidity requirements.

In addition, the EIT Law, and its implementation rules provide that withholding tax rate of up to 10% will be applicable to dividends payable by Chinese companies to non-PRC-resident enterprises unless otherwise exempted or reduced according to treaties or arrangements between the PRC central government and governments of other countries or regions where the non-PRC-resident enterprises are incorporated.

We may not be able to obtain certain treaty benefits on dividends paid to us by our PRC subsidiary through our Hong Kong Subsidiary.

Under the EIT Law, dividends generated from retained earnings after January 1, 2008 from a PRC company and distributed to a foreign parent company are subject to a withholding tax rate of 10% unless the foreign parent’s jurisdiction of incorporation has a tax treaty with China that provides for a preferential withholding arrangement. Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Prevention of Fiscal Evasion with respect to Taxes on Income, or the Hong Kong Tax Treaty, which became effective on December 8, 2006, a company incorporated in Hong Kong, such as Tarena HK, will be subject to withholding income tax at a rate of 5% on dividends it receives from its PRC subsidiary if it holds a 25% or more interest in that particular PRC subsidiary, or 10% if it holds less than a 25% interest in that subsidiary. Pursuant to the Notice of the SAT on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or Circular 81, the 5% withholding tax rate does not automatically apply and certain requirements must be satisfied, including without limitation that (a) the Hong Kong enterprise must be the beneficial owner of the relevant dividends; and (b) the Hong Kong enterprise must directly hold at least 25% share ownership in the PRC enterprise during the 12 consecutive months preceding its receipt of the dividends. However, a transaction or arrangement entered into for the primary purpose of enjoying a preferential tax treatment should not be a reason for the application of the preferential tax treatment under the Hong Kong Tax Treaty. If a taxpayer inappropriately is entitled to such preferential tax treatment, the competent tax authority has the power to make appropriate adjustments. TheAccording to the Circular on Several Issues regarding the “Beneficial Owner” in Tax Treaties, which was issued on February 3, 2018 by the SAT promulgated a tax notice on October 27, 2009,and has taken effect from April 1, 2018, or Circular 601, which provides that tax treaty benefits will be denied to “conduit” or shell companies without business substance, and a beneficial ownership analysis will be used based on a “substance-over-the-form” principle to determine whether or not to grant tax treaty benefits. On June 29, 2012, the SAT further issued the Announcement of the SAT regarding Recognition of “Beneficial Owner” under Tax Treaties, or Announcement 30, which provides that a comprehensive analysis should be made9, when determining the beneficial ownerapplicant’s status basedof the “beneficial owner” regarding tax treatments in connection with dividends, interests or royalties in the tax treaties, several factors, including without limitation whether the applicant is obligated to pay more than 50% of his or her income in twelve months to residents in a third country or region, whether the business operated by the applicant constitutes the actual business activities, and whether the counterparty country or region to the tax treaties levies any tax or grants tax exemption on various factors supported by various typesrelevant incomes or levies tax at an extremely low rate, will be taken into account, and such determination will be analyzed according to the actual circumstances of the specific cases. Circular 9 further provides that applicants who intend to prove his or her status of the “beneficial owner” shall submit the relevant documents includingto the articles of association, financial statements, records of cash movements, board meeting minutes, board resolutions, staffing and materials, relevant expenditures, functions and risk assumption as well as relevant contracts and other information. In August 2015, the SAT promulgatedtax authority according to the Administrative Measures for Non-Resident Taxpayers to Enjoy Treatments under Tax Treaties, or Circular 60, which was issued in August 2015 by the SAT and became effective on November 1, 2015. Circular 60 provides that non-resident enterprises are not required to obtain pre-approval from the relevant tax authority in order to enjoy the reduced withholding tax rate. Instead, non-resident enterprises and their withholding agents may, by self-assessment and on confirmation that the prescribed criteria to enjoy the tax treaty benefits are met, directly apply the reduced withholding tax rate, and file necessary forms and supporting documents when performing tax filings, which will be subject to post-tax filing examinations by the relevant tax authorities. However, if a competent tax authority finds out that it is necessary to apply the general anti-tax avoidance rules, it may start general investigation procedures for anti-tax avoidance and adopt corresponding measures for subsequent administration.Asadministration. As a result, although our PRC subsidiary, Tarena Hangzhou, is currently wholly owned by our Hong Kong subsidiary Tarena HK, we cannot assure you that we would be entitled to the tax treaty benefits and enjoy the favorable 5% rate applicable under the Hong Kong Tax Treaty on dividends. If Tarena HK cannot be recognized as the beneficial owner of the dividends to be paid by Tarena Hangzhou to us, such dividends will be subject to a normal withholding tax of 10% as provided by the EIT Law. Besides, according to Circular 81 and Circular 60, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a preferential tax treatment, the relevant tax authorities may adjust the preferential withholding tax in the future.

Discontinuation or revocation of any of the preferential tax treatments and government subsidies or imposition of any additional taxes and surcharges could adversely affect our financial condition and results of operations.

Our PRC subsidiaries are incorporated in the PRC and governed by applicable PRC tax laws and regulations. The EIT Law and its Implementing Rules, both became effective on January 1, 2008, have adopted a uniform statutory enterprise income tax rate of 25% to all enterprises in China including foreign-invested enterprises. The EIT Law and its Implementation Rules also permit qualified “high and new technology enterprises,” or HNTEs, to enjoy a preferential enterprise income tax rate of 15% upon filing with relevant tax authorities. The qualification as a HNTE generally has a valid term of three years and the renewal of such qualification is subject to review by the relevant authorities in China. Tarena Tech obtained its HNTE certificate in 2009 and renewed its HNTE certificate in 2012 and again in 2015, and is eligible to enjoy a preferential tax rate of 15% until the endfourth quarter of 2017.2018. If Tarena Tech fails to maintain its HNTE qualification or renew its qualification when its current term expires, its applicable enterprise income tax rate may increase to 25%, which could have an adverse effect on our financial condition and results of operations. In addition, Tarena Hangzhou, one of our PRC subsidiaries, was established in 2013 and is qualified as a “newly established software enterprise”, which entitles it to two years of full tax exemption followed by three years of 50% tax exemption, commencing from the year in which its taxable income is greater than zero, which was 2014. Tarena Hangzhou has also received financial subsidies from PRC local government authority in 2013, 2015 and 2016. In 2016, Tarena Hangzhou acquired Hanru Education & TechnologyCo.Technology Co., Ltd., or Hanru Hangzhou, which was qualified as an eligible software enterprise and entitled to a full tax exemption of two years followed by a 50% tax exemption of three years, commencing from 2016.

Preferential tax treatments and financial subsidies are subject to review and may be adjusted or revoked at any time in the future. The discontinuation of any preferential tax treatments or financial subsidies or imposition of any additional taxes could adversely affect our financial condition and results of operations.

Fluctuations in exchange rates could have a material adverse effect on our results of operations and the value of your investment.

The value of the Renminbi against the U.S. dollar and other currencies is affected by, among other things, changes in China’s political and economic conditions and China’s foreign exchange policies. The PRC government changed its decade-old policy of pegging the value of the RMB to the U.S. dollar in 2005, and the Renminbi appreciated more than 20% against the U.S. dollar over the following three years. However, the People’s Bank of China regularly intervenes in the foreign exchange market to limit fluctuations in Renminbi exchange rates and achieve policy goals. During the period between July 2008 and June 2010, the exchange rate between the RMB and the U.S. dollar had been stable and traded within a narrow range. However, the Renminbi fluctuated significantly during that period against other freely traded currencies, in tandem with the U.S. dollar. Since June 2010, the RMB has fluctuated against the U.S. dollar, at times significantly and unpredictably. In August 2015, the People’s Bank of China changed the way it calculates the mid-point price of Renminbi against the U.S. dollar, requiring the market-makers who submit for reference rates to consider the previous day’s closing spot rate, foreign-exchange demand and supply as well as changes in major currency rates. The value of the Renminbi depreciated approximately 5.8% against the U.S. dollar in 2015 and further by approximately 6.3% in 2016. On November 30, 2015, the Executive Board of the International Monetary Fund (IMF) completed the regular five-year review of the basket of currencies that make up the Special Drawing Right, or the SDR, and decided that with effect from October 1, 2016, Renminbi is determined to be a freely usable currency and will be included in the SDR basket as a fifth currency, along with the U.S. dollar, the Euro, the Japanese yen and the British pound. In the fourth quarter of 2016, the RMB has depreciated significantly in the backdrop of a surging U.S. dollar and persistent capital outflows of China. With the development of the foreign exchange market and progress towards interest rate liberalization and Renminbi internationalisation,internationalization, the PRC government may in the future announce further changes to the exchange rate system and we cannot assure you that the Renminbi will not appreciate or depreciate significantly in value against the U.S. dollar in the future. It is difficult to predict 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.

Significant revaluation of the RMB may have a material and adverse effect on your investment. For example, to the extent that we need to convert U.S. dollars into RMB for capital expenditures and working capital and other business purposes, appreciation of the RMB against the U.S. dollar would have an adverse effect on the 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 payments 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 negative effect on the 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 the U.S. dollar equivalent of our earnings, regardless of any underlying change in our business or results of operations.

In January 2016, we entered into a foreign currency forward contract with China Merchants Bank Co., Ltd. The notional amounts of the foreign currency forward contracts were RMB564.1 million and the settlement date was on May 19, 2016. We incurred a loss of RMB12.9 million as a result of such forward foreign currency contract in 2016, due2016. The contract expired in May 2017, and we do not have entered into any new foreign currency forward contract in 2017. Due to the fluctuation in the exchange rate between U.S. dollars and RMB. WeRMB, we may decide to enter into additional foreign currency contract in the future, 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, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert Renminbi into foreign currency. As a result, fluctuations in exchange rates may have a material adverse effect on your investment.

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, as such, you are deprived of the benefits of such inspection.

Auditors of companies that are registered with the U.S. 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 U.S. Public Company Accounting Oversight Board (United States), or PCAOB, and are required by the laws of the United States to undergo regular inspections by the PCAOB to assess their compliance with the laws of the United States and professional standards. Because our auditor is located in the Peoples’ Republic of China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the PRC authorities, our auditor is not currently inspected by the PCAOB. In May 2013, PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation with the CSRC and the PRC Ministry of Finance, which establishes a cooperative framework between the parties for the production and exchange of audit documents relevant to investigations undertaken by PCAOB, the CSRC or the PRC Ministry of Finance in the United States and the PRC, respectively. PCAOB continues to be in discussions with the CSRC and the PRC Ministry of Finance to permit joint inspections in the PRC of audit firms that are registered with PCAOB and audit Chinese companies that trade on U.S. exchanges.

This lack of PCAOB inspections in China prevents the PCAOB from regularly evaluating audits and quality control procedures of any auditors operating in China, including our auditor. As a result, investors may be deprived of the benefits of PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to PCAOB inspections. Investors may lose confidence in our reported financial information and procedures and the quality of our financial statements.

Proceedings instituted by the SEC against certain China-based accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act.

On January 22, 2014, Judge Cameron Elliot, an SEC administrative law judge, issued an initial decision suspending the Chinese member firms of the “Big Four” accounting firms, including our independent registered public accounting firm, from, among other things, practicing before the SEC for six months. In February 2014, the initial decision was appealed. While under appeal and in February 2015, the Chinese member firms of the “Big Four” accounting firms reached a settlement with the SEC. As part of the settlement, each of the Chinese member firms of the “Big Four” accounting firms agreed to settlement terms that include a censure; undertakings to make a payment to the SEC; procedures and undertakings as to future requests for documents by the SEC; and possible additional proceedings and remedies should those undertakings not be adhered to.

If the settlement terms are not adhered to, Chinese member firms of the “Big Four” accounting firms may be suspended from practicing before the SEC. If our independent registered public accounting firm were suspended, from practicing before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to our delisting from the NASDAQ Global Select Market or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

Substantial uncertainties exist with respect to the enactment timetable, interpretation and implementation of draft PRC Foreign Investment Law and how it 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 trio of existing laws regulating foreign investment in China, namely,the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Wholly Foreign-invested Enterprise Law, together with their implementation rules and ancillary regulations. The draft Foreign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. While the Ministry of Commerce solicited comments on this draft earlier this year, substantial uncertainties exist with respect to its enactment timetable, interpretation and implementation. The draft Foreign Investment Law, if enacted as proposed, may materially impact 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 a company is considered a foreign-invested enterprise, or an FIE. The draft Foreign Investment Law specifically provides that entities established in China but “controlled” by foreign investors will be treated as FIEs. Once an entity is determined to be an FIE, it will be subject to the foreign investment restrictions or prohibitions set forth in a “negative list” to be separately issued by the State Council later. The “negative list” will consist of a list of industry categories where foreign investments are strictly prohibited and a list of industry categories where foreign investments are subject to certain restrictions. Foreign investments in business sectors outside of the “negative list” will only be subject to filing procedures, whereas foreign investments in the restricted industries must apply for prior approval from the foreign investment administration authority. In case the underlying business of an FIE falls within the foreign investment restricted industries, upon market entry clearance by the MOFCOM, the FIE may file an application for being treated as a PRC domestic investment if the FIE is “controlled” by PRC entities and/or citizens. In this connection, “control” is broadly defined in the draft law to cover the following summarized categories: (i) holding 50% or more of the voting rights of the subject entity; (ii) holding less than 50% of the voting rights of the subject entity but having the power to secure at least 50% of the seats on the board or other equivalent decision making bodies, or having the voting power to exert material influence on the board, the shareholders’ meeting or other equivalent decision making bodies; or (iii) having the power to exert decisive influence, via contractual or trust arrangements, over the subject entity’s operations, financial matters or other key aspects of business operations.

The “variable interest entity” structure, or VIE structure, has been adopted by many PRC-based companies, including us, to obtain necessary licenses and permits in the industries that are currently subject to foreign investment restrictions in China. See “—Risks Relating to Our Corporate Structure—If the PRC government finds that the agreements that establish the structure for holding our ICP license do not comply with applicable PRC laws and regulations, we could be subject to severe penalties” and “Item 4. Information on the Company—C. Organizational Structure.” Under the draft Foreign Investment Law, variable interest entities that are controlled via contractual arrangement would also be deemed as FIEs, if they are ultimately “controlled” by foreign investors. Therefore, for any companies with a VIE structure 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 of PRC nationality (including PRC citizens, PRC governmental authorities and their affiliates, and the PRC companies controlled by the foregoing). Conversely, if the actual controlling person(s) is/are of foreign nationalities, then the variable interest entities will be treated as FIEs and any operation in the industry category on the “negative list” without market entry clearance may be considered as illegal.

Through our dual-class share structure, Mr. Shaoyun Han, our founder, chairman and chief executive officer, a PRC citizen, possessed and controlled 67.1%67.6% of the voting power of our company as of March 31, 2017.2018. 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. Moreover, it is uncertain whether the Internet content and other value-added telecommunication service industry, in which our VIE operates, will be subject to the foreign investment restrictions or prohibitions set forth in the “negative list” to be issued. If the enacted version of the Foreign Investment Law and the final “negative list” mandate further actions, such as MOFCOM market entry clearance or certain restructuring of our corporate structure and operations, to be completed by companies with existing VIE structure like us, we face substantial uncertainties as to whether these actions can be timely completed, or at all, and our business and financial condition may be materially and adversely affected.

The draft Foreign Investment Law, if enacted as proposed, may also materially impact our corporate governance practice and increase our compliance costs. For instance, the draft Foreign Investment Law imposes stringent ad hoc and periodic information reporting requirements on foreign investors and the applicable FIEs. Aside from investment implementation report and investment amendment report that are required at each investment and alteration of investment specifics, an annual report is mandatory, and large foreign investors meeting certain criteria are required to report on a quarterly basis. Any company found to be non-compliant with these information reporting obligations may potentially be subject to fines and/or administrative or criminal liabilities, and the persons directly responsible may be subject to criminal liabilities.

Risks Relating to Our ADSs

The trading prices of our ADSs have fluctuated and may be volatile, which could result in substantial losses to investors.

The trading prices of our ADSs have fluctuated since we first listed our ADSs.TheADSs. The trading price of our ADSs has ranged from US$8.3512.52 to US$17.7521.70 per ADS in 2016.2017. The last reported trading price on April 24, 201727, 2018 was US$18.6010.01 per ADS. The trading prices of our ADSs may continue to fluctuate and be volatile due to factors beyond our control. This may happen because of broad market and industry factors, like the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States. In recent years, the widespread negative publicity of alleged fraudulent accounting practices and poor corporate governance of certain U.S. public companies with operations in China were believed to have negatively affected investors’ perception and sentiment towards companies with connection with China, which significantly and negatively affected the trading prices of some companies’ securities listed in the U.S. Any similar negative publicity or sentiment may affect the performances of our ADSs. A number of PRC companies have recently listed or are in the process of listing their securities on U.S. stock markets. The securities of some of these companies have experienced significant volatility, including price declines in connection with their initial public offerings. The trading performances of these PRC companies’ securities after their offerings may affect the attitudes of investors toward PRC companies listed in the United States in general and consequently may impact the trading performance of our ADSs, regardless of our actual operating performance.

In addition to market and industry factors, the price and trading volume for our ADSs may be highly volatile for factors specific to our own operations, including the following:

Any of these factors may result in large and sudden changes in the volume and price at which our ADSs will trade.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding our ADSs, the market price for our ADSs and trading volume could decline.

The trading market for our ADSs is influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade our ADSs or publish unfavorable research about us, the market price for our ADSs would likely decline. If one or more of these analysts cease to cover us or fail to 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 our ADSs to decline.

Our dual class share structure with different voting rights will limit your ability to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.

Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of Class A ordinary shares are entitled to one vote per share, while holders of Class B ordinary shares are entitled to ten votes per share, with Class A and Class B ordinary shares voting together as one class on all matters subject to a shareholders’ vote. As of March 31, 2017,2018, our Class B ordinary shares represent 12.6%12.8% of our total outstanding ordinary shares on an as-converted basis and entitle their holders to 59.0%59.4% of our total voting power.

As a result of the dual class share structure and the concentration of ownership, holders of our Class B ordinary shares have substantial influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. They may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of our ADSs. This concentrated control will limit your ability to influence corporate matters and could discourage others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A ordinary shares and ADSs may view as beneficial. For more information regarding our principal shareholders and their affiliated entities, see “Item 7. Major Shareholders and Related Party Transactions.”

The sale or availability for sale of substantial amounts of our ADSs could adversely affect their market price.

Sales of substantial amounts of our ADSs in the public market, or the perception that these sales could occur, could adversely affect the market price of our ADSs and could materially impair our ability to raise capital through equity offerings in the future. We cannot predict what effect, if any, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale will have on the market price of our ADSs. In addition, certain holders of our existing shareholders are entitled to certain registration rights, including demand registration rights, piggyback registration rights, and Form F-3 or Form S-3 registration rights. Registration of these shares under the Securities Act would result in these shares becoming freely tradable without restriction under the Securities Act immediately upon the effectiveness of the registration. Sales of these registered shares in the public market, or the perception that such sales could occur, could cause the price of our ADSs to decline.

We may be classified as a passive foreign investment company for United States federal income tax purposes, which could result in adverse United States federal income tax consequences to United States investors in the ADSs or ordinary shares.

We will be classified as a “passive foreign investment company,” or “PFIC” if, in the case of any particular taxable year, either (a) 75% or more of our gross income for such year consists of certain types of “passive” income or (b) 50% or more of the average quarterly value of our assets (as determined on the basis of fair market value) during such year produce or are held for the production of passive income. Passive income generally includes dividends, interest, royalties, rents, annuities, net gains from the sale or exchange of passive assets (including property producing passive income) and net foreign currency gains. For this purpose, cash is categorized as a passive asset and the company’s unbooked intangibles associated with active business activity are taken into account as a non-passive asset. We will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the stock.

Based on our current income and assets and the value of our ADSs and outstanding ordinary shares, we do not believe that we were a PFIC for our taxable year ended December 31, 20162017 and we do not expect to be classified as a PFIC for our taxable year ending December 31, 20172018 or in the foreseeable future.

While we do not expect to become a PFIC, because the value of our assets for purposes of the asset test will generally be determined by reference to the market price of our ADSs or ordinary shares, fluctuations in the market price of our ADSs or ordinary shares may cause us to become a PFIC for the current or subsequent taxable years. The determination of whether we will be or become a PFIC will also depend, in part, on the composition of our income and assets, which will be affected by how, and how quickly, we use our liquid assets. Under circumstances where we determine not to deploy significant amounts of cash for active purposes, our risk of being classified as a PFIC may substantially increase. Because there are uncertainties in the application of the relevant rules and PFIC status is a factual determination made annually after the close of each taxable year, there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year.

If we are classified as a PFIC in any taxable year, a U.S. Holder (as defined in “Item 10. Additional Information—E. Taxation—United States Federal Income Tax Considerations—Passive Foreign Investment Company Considerations”) may incur significantly increased United States income tax on gain recognized on the sale or other disposition of the ADSs or ordinary shares and on the receipt of distributions on the ADSs or ordinary shares to the extent such gain or distribution is treated as an “excess distribution”distribution” under the United States federal income tax rules and such holders may be subject to burdensome reporting requirements. Further, if we are classified as a PFIC for any year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares. For more information, see “Item 10. Additional Information—E. Taxation—United States Federal Income Tax Considerations—Passive Foreign Investment Company Considerations.”

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law of the Cayman Islands (2016 Revision) and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have the standing to initiate a shareholder derivative action in a federal court of the United States.

The Cayman Islands courts are also unlikely:

There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will in certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands company and almost all of our assets are located outside of the United States. All of our current operations are conducted in China. In addition, most of our current directors and executive officers are nationals and residents of countries other than the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the United States federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to vote your Class A ordinary shares.

As a holder of our ADSs, you will only be able to exercise the voting rights with respect to the underlying Class A ordinary shares in accordance with the provisions of the deposit agreement. Under the deposit agreement, you must vote by giving voting instructions to the depositary. Upon receipt of your voting instructions, the depositary will vote the underlying Class A ordinary shares in accordance with these instructions. You will not be able to directly exercise your right to vote with respect to the underlying shares unless you withdraw the shares. Under our amended and restated memorandum and articles of association, as amended, the minimum notice period required for convening a general meeting is ten clear days. When a general meeting is convened, you may not receive sufficient advance notice to withdraw the shares underlying your ADSs to allow you to vote with respect to any specific matter. If we ask for your instructions, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to vote and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested.

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 intend to take advantage of certain exemptions from various requirements that are applicable to other public companies that are not emerging growth companies including, most significantly, not being required to comply with the auditor attestation requirements of Section 404 for so long as we are an emerging growth company, which may be for as long as five years following our initial public offering in April 2014. As a result of our current status as an emerging growth company, our investors may not have access to certain information that they may deem important.

The JOBS Act also provides that an emerging growth company does not need to comply with any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. However, we had 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. The decision to opt out of the extended transition period under the JOBS Act was irrevocable.

We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to United States domestic public companies.

Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including:

We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we publish our results on a quarterly basis as press releases, distributed pursuant to the rules and regulations of the NASDAQ Global Select Market. Press releases relating to financial results and material events are also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC are less extensive and less timely as compared to that required to be filed with the SEC by United States domestic issuers. As a Cayman Islands company listed on the NASDAQ Global Select Market, we are subject to the NASDAQ Global Select Market corporate governance listing standards. However, NASDAQ Global Select Market rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the NASDAQ Global Select Market corporate governance listing standards.

We relied on the exemption available to foreign private issuers for the requirement that it hold an annual general meeting of shareholders no later than December 31, 20162017 in 2016.2017. In this respect, we elected to follow home country practice and did not hold an annual general meeting of shareholders no later than December 31, 20162017 in 2016.2017. We may also continue to rely on this and other exemptions available to foreign private issuers in the future, and to the extent that we choose to do so in the future, our shareholders may be afforded less protection than they otherwise would under the NASDAQ Global Select Market corporate governance listing standards applicable to U.S. domestic issuers. As a result, you may not be afforded the same protections or information, which would be made available to you, were you investing in a United States domestic issuer.

You may not receive dividends or other distributions on our Class A ordinary shares and you may not receive any value for them, if it is illegal or impractical to make them available to you.

The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on Class A ordinary shares or other deposited securities underlying our ADSs, after deducting its fees and expenses. You will receive these distributions in proportion to the number of Class A ordinary shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities that require registration under the Securities Act but that are not properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not feasible to distribute certain property through the mail. Additionally, the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under U.S. securities laws any ADSs, ordinary shares, rights or other securities received through such distributions. We also have no obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that you may not receive distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may cause a material decline in the value of our ADSs.

You may not be able to participate in rights offerings and may experience dilution of your holdings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

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 books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We incur increased costs as a result of being a public company, and we cannot predict or estimate the amount of additional future costs we may incur or the timing of such costs

As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company, including additional costs associated with our public company reporting obligations. The Sarbanes-Oxley Act of 2002, as well as rules subsequently implemented by the SEC and NASDAQ Global Select Market, impose various requirements on the corporate governance practices of public companies. As a company with less than US$1.07 billion in revenues for our last fiscal year, we qualify as an “emerging growth company” pursuant to the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include exemption from the auditor attestation requirement under Section 404 in the assessment of the emerging growth company’s internal control over financial reporting and permission to delay adopting new or revised accounting standards until such time as those standards apply to private companies. However, we had 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. The decision to opt out of the extended transition period under the JOBS Act was irrevocable.

We expect these rules and regulations to increase our legal and financial compliance costs and to make some corporate activities more time-consuming and costly. After we are no longer an “emerging growth company,” we expect to incur significant expenses and devote substantial management effort toward ensuring compliance with the requirements of Section 404 and the other rules and regulations of the SEC. We are currently evaluating and monitoring developments with respect to these rules and regulations, and we cannot predict or estimate with reasonable certainty the amount of additional costs we may incur or the timing of such costs.

In the past, shareholders of a public company often brought securities class action suits against the company following periods of instability in the market price of that company’s securities. In the fourth quarter of 2015, several law firm in the U.S. announced that they were investigating potential securities claims on behalf of our shareholders against us. We cannot predict whether such investigations will result in lawsuits, including class action suits, being filed against us. If we were involved in a class action suit, it 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 suit. Any such class action suit, whether or not successful, 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 be required to pay significant damages, which could have a material adverse effect on our financial condition and results of operations.

We began our operations in Beijing in September 2002 through Beijing Tarena Technology Co., Ltd. In November 2012, we changed the name of Beijing Tarena Technology Co., Ltd. to Tarena Technologies Inc., or Tarena Tech. Tarena International, Inc., an exempted company with limited liability, was incorporated in the Cayman Islands in October 2003 and became our ultimate holding company. We established Tarena Hong Kong Limited, or Tarena HK, as our wholly-owned subsidiary in October 2012. Tarena HK wholly owns Tarena Software Technology (Hangzhou) Co., Ltd., or Tarena Hangzhou, an entity that we established in January 2013.

On April 3, 2014, our ADSs began trading on the NASDAQ Global Select Market under the ticker symbol “TEDU.” We and certain selling shareholders sold a total of 15,300,000 ADSs, representing 15,300,000 Class A ordinary shares, at an initial offering price of $9.00 per ADS. Concurrently with our initial public offering, we also issued 1,500,000 Class A ordinary shares at a price of US$9.00 per share to New Oriental Education & Technology Group Inc. Ltd. through a private placement.

Prior to 2012, we conducted a substantial portion of our operations through our consolidated VIEs and their respective subsidiaries and schools. On January 30, 2012, thePRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective, which listed professional education service as an industry for which foreign investments are “encouraged” by the government andgovernment. On April 10, 2015, the newPRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective, which listed non accreditednon-accredited professional education service as an industry for which foreign investments are “encouraged” by the government. On July 28, 2017, the newPRC Catalogue for the Guidance of Foreign Investment Industries (amended) became effective, which listed non-accredited professional education service as an industry for which foreign investments are “encouraged” by the government. In light of such change of law, starting from the second half of 2012, we began to transfer the operations, including related assets and liabilities, of our consolidated VIEs to Tarena Tech and its subsidiaries and schools. All of our learning center operations of VIEs had been transferred to Tarena Tech and its subsidiaries and schools. In December 2016, we wound up Shanghai Tarena, one of our VIEs. We expect to continue to control and consolidate Beijing Tarena, which holds an Internet Content Provider license, or ICP license. Beijing Tarena has added ourTMOOC.cn website under the ICP license held by Beijing Tarena. For a description of the risks relating to our corporate structure and the contractual arrangements we have entered into with our VIE, see “Item 3. Key Information—D.

In 2015, we invested RMB24.0 million in five PRC companies which are engaged in the provision of educational products and services. In 2016, we invested RMB12.8 million in three companies which are mainly engaged in the provision of educational products and services.

We complement the live instruction and tutoring with our proprietary learning management system TTS. TTS has five core functions, featuring course content, self-assessment exams, student and teaching staff interaction tools, student management tools and an online student community. Through this education platform, we provide job-oriented education with measurable outcomes, as demonstrated by our high job placement rates and students’ academic performance. In addition to our TTS platform, we launchedTMOOC.cn in March 2015, which offers not only regular teaching video contents, but also continuing education courses and job placement training courses, in order to cover a broader customer base.

Our Education Platform

For our adult students, our education platform combines three key components: live distance instruction, classroom-based tutoring and online learning modules.

Live distance instruction

From our headquarters in Beijing, our instructors deliver live courses primarily via live webcast to our learning centers across China. Students attending class watch live audio-video broadcasts of lectures delivered using streaming media and other Internet-based technologies. Our full-time students typically watch live lectures for approximately five hours a day and work on practice exercises assigned by instructors for approximately two hours every day during the classroom sessions, which generally last from 9:00 a.m. to 6:00 p.m. five days a week.

Our live broadcast method of lecture delivery ensures consistency in teaching quality across all our centers. All of our instructors to deliver the lecture through webcasting system are located in Beijing, where we centralize our training support. Our headquarter-level quality control department monitors the performance of each lecturer on a daily basis. We typically have multiple instructors for each course, with each instructor focusing on separate topic areas. We believe this allows our instructors to focus, and offer more in-depth teaching, on their specific areas of expertise within a subject.

Classroom-based tutoring

Our students are generally required to physically attend classes at our learning centers. We believe physical attendance is important as it creates a disciplined and focused learning environment for students to effectively master the course content. Requiring students to physically attend classes also facilitates the delivery of personalized and systematic tutoring and job placement services to our students.

In terms of professional education programs, our classrooms are equipped with computers for each student, as well as projectors and other equipment necessary for the live broadcast of our lectures. Our classroom technology infrastructure allows students to interact with instructors online to receive help on course materials and to use online modules in TTS to take notes and conduct practice exercises.

Our learning centers function both as classrooms for delivering lectures and self-study rooms after class hours. As of December 31, 2016,2017, we directly managed a total of 145184 learning centers in 4659 major cities across China. Our learning centers vary in terms of size, typically having between 5 and 20 classrooms, with each classroom typically able to host between 20 and 100 students. In addition to the learning centers that we operate directly, we also have one franchised learning center in Xi’an, and the franchise fee from such learning center was immaterial in 2016.2017.
