AutoHome (ATHM) Risk Analysis

On August 31, 2018, the Standing Committee of the National People's Congress of China issued the E-commerce Law, which came into effect on January 1, 2019. Pursuant to the E-commerce Law, operators of e-commerce platforms shall verify and register the basic information of e-commerce operators on their platforms, including the identity, address, contact and administrative license, and establish archives with regular updates for such information. It further provides that operators of e-commerce platforms shall submit information on the identification of e-commerce operators to department for market regulation, and submit e-commerce operators' identification information and other information relating to tax payment to tax authority. Additionally, operators of e-commerce platforms shall record and save information released on their platform about commodities and services, and report to competent authorities, if such information show that e-commerce operators have failed to obtain the administrative license when they are subject to the relevant administrative approval, or commodities sold or services offered by e-commerce operators are found to be in violation of certain requirements to safeguard personal safety, property security and the requirements on environmental protection, or to be prohibited by laws and administrative regulations. The E-commerce Law establishes obligations to protect consumers for operators of e-commerce platforms, such as obligations to protect consumers' personal information and record information of deals concluded on their platforms, obligations to refund guarantee deposits to consumers in a timely manner and obligations to noticeably label commodities or services ranked under competitive bidding with the word "Advertisement". E-commerce operators shall not conduct false or misleading commercial publicity by fabricating transactions, making up user reviews or any other means, to cheat or mislead consumers. E-commerce platform operators shall not delete consumers' ratings of commodities sold or services provided on the platform. We have carried out compliance work in accordance with these regulatory requirements. However, in consideration that the current year is the first year since the E-commerce Law became effective, there are substantial uncertainties with respect to the interpretation and implementation of the E-commerce Law and how it may impact our business operations. We cannot guarantee that the compliance measures we have taken are fully consistent with the interpretation of regulators, and there is a risk that the company will be punished by those regulators because of any non-compliance activities.

In December 2018, the National People's Congress of the PRC published a draft of the proposed Foreign Investment Law for soliciting public comments. In March 2019, the Foreign Investment Law was enacted by the National People's Congress and it will become effective in January 2020. Upon its enactment, it will 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 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. The 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 "Item 7. Major Shareholders and Related Party Transactions-B. Related Party Transactions-Contractual Arrangements with Our Variable Interest Entities" and "Item 3. Key Information-D. Risk Factors-Risks Related to Our Corporate Structure-If the PRC government finds that the agreements that establish the structure for operating our services in China do not comply with PRC governmental restrictions on foreign investment in internet businesses, or if these regulations or the interpretation of existing regulations change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations." Although the Foreign Investment Law does not explicitly classify "contractual arrangements" as a form of foreign investment, it contains a catch-all provision under the definition of "foreign investment" which includes investments made by foreign investors through means stipulated in laws or administrative regulations or other methods prescribed by the State Council. Therefore, it still reserves certain leeway for future legislation by the Stale Council to provide "contractual arrangements" as a form of foreign investment, in which case it will be uncertain as to whether our contractual arrangements with our VIEs will be deemed to be in violation of the market access requirements for foreign investments under the PRC laws and regulations, such as the foreign investment restrictions set forth in the Catalogue for the Guidance of Foreign Investment Industries, or the Catalogue, issued by the NDRC and the MOFCOM in March 2015 and revised in June 2017 and the Special Administrative Measures for Foreign Investment Access, or the Negative List, issued by the MOFCOM in July 2018. According to the Catalogue and the Negative List, the provision of internet content services, which we conduct through our VIEs, is subject to foreign investment restrictions. Therefore, such foreign investment restrictions will be inevitably imposed on our VIEs if our contractual arrangements with our VIEs are further defined or regarded as a form of foreign investment by any future provisions stipulated in laws or administrative regulations or other methods prescribed by the State Council. In addition, if future laws, administrative regulations or provisions prescribed by the State Council mandate further actions to be taken by companies with respect to existing contractual arrangements, we may face substantial uncertainties as to whether we could complete such actions in a timely manner, or at all, and our business and financial condition may be materially and adversely affected. Given the foregoing, uncertainties still exist in relation to the interpretation and implementation of the Foreign Investment Law, which may result in adverse impact on our current corporate structure. If our contractual arrangements with our VIEs are defined or regarded as a form of foreign investment in the future, our corporate governance practice may be impacted and our compliance costs may increase. For instance, the Foreign Investment Law requires foreign investors or foreign-funded enterprises to submit the investment information to competent governmental authorities for review. Although the contents and scope of such information shall be determined under the principle of necessity and the information that can be obtained through interdepartmental information sharing will not be required to be resubmitted, foreign investors or foreign-funded enterprises which fail to report their investment information as requested will be required to take corrective measures or be subject to fines. Moreover, the Foreign Investment Law provides that a security examination mechanism will be established to examine any foreign investment activity that affects or may affect national security. The decision made upon the security examination may impact the operations of the foreign-funded enterprises.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason in accordance with the terms of the deposit agreement.

Current PRC laws and regulations place certain restrictions on foreign ownership of companies that provide internet content services in China. Specifically, foreign ownership of internet service providers or other value-added telecommunication service providers may not exceed 50%. In addition, according to the Several Opinions on the Introduction of Foreign Investment in the Cultural Industry promulgated by the Ministry of Culture, the State Administration of Radio, Film and Television, or the SARFT, the General Administration of Press and Publication, or the GAPP, the National Development and Reform Commission, or the NDRC, and the Ministry of Commerce, or the MOFCOM, in July 2005, foreign investors are prohibited from investing in or operating "internet cultural activities." We are a Cayman Islands company and foreign legal person under PRC laws. Accordingly, neither we nor our wholly foreign-invested PRC subsidiaries are currently eligible to apply for the required licenses for providing internet content services in China. As such, we conduct our business activities related to internet content services by entering into a series of contractual arrangements with two of our VIEs in China, namely Beijing Autohome Information Technology Co., Ltd., or Autohome Information, Beijing Shengtuo Hongyuan Information Technology Co., Ltd., or Shengtuo Hongyuan, and their respective shareholders. In particular, Autohome Information currently holds an ICP license, a Surveying and Mapping Qualification Certificate for Internet Mapping, an Operating License for the Production and Dissemination of Radio and Television Programs, an internet Audio/Video Program Transmission License, and an Internet Culture Business Permit. In addition, Autohome Information is the sole shareholder of Shanghai Tianhe, an insurance brokerage company, which has completed the registration process required for engaging in online insurance business in the PRC. Shengtuo Hongyuan currently holds an ICP license, a Surveying and Mapping Qualification Certificate for Internet Mapping, an Operating License for the Production and Dissemination of Radio and Television Programs and is operating the che168.com website and automobile application-related business. These two VIEs are currently owned by individual shareholders who are PRC citizens and hold the requisite licenses or permits to operate internet business in China. We do not have any equity interests in these two VIEs but substantially control their operations and receive the economic benefits through contractual arrangements. We have been and are expected to continue to be dependent upon these two VIEs and their respective subsidiaries for the above mentioned business operations. For more information regarding these contractual arrangements, see "Item 7. Major Shareholders and Related Party Transactions-B. Related Party Transactions-Contractual Arrangements with Our Variable Interest Entities." In consideration of the previous restrictions imposed on the shareholders of foreign-invested companies engaging in advertising business, we once conducted advertising business by entering into a series of contractual arrangements with the other two VIEs in China, namely Guangzhou You Che You Jia Advertising Co., Ltd., or Guangzhou Advertising, and Shanghai You Che You Jia Advertising Co., Ltd., or Shanghai Advertising, and two subsidiaries of Autohome Information, Beijing Shengtuo Autohome Advertising Co., Ltd., or Autohome Advertising, and Beijing Shengtuo Chengshi Advertising Co., Ltd., or Chengshi Advertising. Since the relevant regulatory environment developed, such restrictions were lifted in 2015. Therefore, in 2015, we completed the migration of our advertising business from Guangzhou Advertising, Shanghai Advertising and other PRC entities to the PRC subsidiaries of Autohome Media Limited, or Autohome Media, a Hong Kong advertising and marketing company previously named as Prbrownies Marketing Limited. We have completed the dissolution and deregistration of Guangzhou Advertising in December 2018. Shanghai Advertising currently is not conducting any business and is in the process of liquidation and dissolution, which is expected to be completed by the end of 2019. Based on the advice of our PRC legal counsel, Commerce & Finance Law Offices, the corporate structure of our VIEs and our subsidiaries in China are in compliance with all existing PRC laws and regulations. However, as there are substantial uncertainties regarding the interpretation and application of PRC laws and regulations, we cannot assure you that the PRC government would agree that our corporate structure or any of the above contractual arrangements comply with PRC licensing, registration or other regulatory requirements, with existing policies or with requirements or policies that may be adopted in the future. PRC laws and regulations governing the validity of these contractual arrangements are uncertain and the relevant government authorities have broad discretion in interpreting these laws and regulations. If we or any of our current or future VIEs or subsidiaries are found to be in violation of any existing or future PRC laws or regulations, or fail to obtain or maintain any of the required permits or approvals, the relevant PRC regulatory authorities, including the Ministry of Industry and Information Technology, or the MIIT, the Cyberspace Administration of China, which regulates internet information services companies, the China Banking and Insurance Regulatory Commission, or CBIRC, whose predecessor is China Insurance Regulatory Commission, and the China Securities Regulatory Commission, or the CSRC, would have broad discretion in dealing with such violations, including levying fines, confiscating our income or the income of Autohome WFOE, Beijing Chezhiying Technology Co., Ltd., or Chezhiying WFOE and the VIEs, revoking the business licenses or operating licenses of Autohome WFOE, Chezhiying WFOE and the VIEs, shutting down our servers or blocking our websites and mobile applications, discontinuing or placing restrictions or onerous conditions on our operations, requiring us to undergo a costly and disruptive restructuring, or taking other enforcement actions that could be harmful to our business. Any of these actions could cause significant disruption to our business operations and severely damage our reputation, which would in turn materially and adversely affect our business and results of operations. In addition, if the imposition of any of these penalties causes us to lose the rights to direct the activities of the VIEs or our right to receive their economic benefits, we would no longer be able to consolidate the VIEs.

We are an offshore holding company conducting our operations in China through our PRC subsidiaries and VIEs. We may make loans to our PRC subsidiaries and VIEs, or we may make additional capital contributions to our PRC subsidiaries. Any loans by us to our PRC subsidiaries, which are treated as foreign-invested enterprises under PRC law, are subject to PRC regulations and foreign exchange loan registrations. For example, loans by us to our PRC subsidiaries to finance its activities cannot exceed statutory limits and must be registered with the competent local counterpart of the State Administration of Foreign Exchange, or SAFE. We may also decide to finance our PRC subsidiaries by means of capital contributions. These capital contributions must be filed with the MOFCOM or its local counterpart. Due to the restrictions imposed on loans in foreign currencies extended to any PRC domestic companies, we are not likely to make such loans to our VIEs, which are PRC domestic companies. Further, we are not likely to finance the activities of our VIEs by means of capital contributions due to regulatory restrictions relating to foreign investment in PRC domestic enterprises engaged in internet content services. Pursuant to both of SAFE Circular 19 and SAFE Circular 16 promulgated in March 2015 and June 2016, respectively, foreign-invested enterprises may either continue to follow the current payment-based foreign currency settlement system or choose to follow the "conversion-at-will" system for foreign currency settlement. SAFE Circular 19 and SAFE Circular 16, therefore, have substantially lifted the restrictions on the usage by a foreign-invested enterprise of its Renminbi registered capital, foreign debt and repatriated funds raised through overseas listing converted from foreign currencies. According to SAFE Circular 19 and SAFE Circular 16, such Renminbi capital, foreign debt and repatriated funds raised through overseas listing may be used at the discretion of the foreign-invested enterprise and SAFE will eliminate the prior approval requirement and only examine the authenticity of the declared usage afterwards. Nevertheless, it is still not clear whether foreign-invested enterprises like our PRC subsidiaries are allowed to extend intercompany loans to our VIEs. In addition, as SAFE Circular 19 and SAFE Circular 16 were promulgated recently, there remain substantial uncertainties with respect to the interpretation and implementation of these circulars by relevant authorities. See "Item 4. Information on the Company-B. Business Overview-PRC Regulation-Regulations on Foreign Exchange." In light of the various requirements imposed by PRC regulations on loans to and direct investment in PRC entities by offshore holding companies, we cannot assure you that we will be able to complete the necessary government registrations or obtain the necessary government approvals on a timely basis, if at all, with respect to future loans by us to our PRC subsidiaries or with respect to future capital contributions by us to our PRC subsidiaries. If we fail to complete such registrations or obtain such approvals, our ability to use the proceeds we received from our equity offerings and to capitalize or otherwise fund our PRC operations may be negatively affected, which could materially and adversely affect our liquidity and our ability to fund and expand our business.

The PRC government extensively regulates the internet industry, including foreign ownership of, and the licensing and permit requirements pertaining to, companies in the internet industry. These internet-related laws and regulations are relatively new and evolving, and their interpretation and enforcement involve significant uncertainties. As a result, in certain circumstances it may be difficult to determine what actions or omissions may be deemed to be violations of applicable laws and regulations. Issues, risks and uncertainties relating to the PRC government regulation of the internet industry include, but are not limited to, the following: -   We only have contractual control over our websites and mobile applications. We do not own the websites or the mobile applications due to the restriction on foreign investment in businesses providing value-added telecommunication services in China, which include internet content provision services. -   There are uncertainties relating to the regulation of the internet industry in China, including evolving licensing requirements. This means that permits, licenses or operations at some of our subsidiaries and VIEs may be subject to challenge, or we may fail to obtain permits or licenses that applicable regulators may deem necessary for our operations, or we may not be able to obtain or renew permits or licenses. For example, both Autohome Information and Shengtuo Hongyuan may be required to obtain additional licenses, including internet publishing licenses and internet news information service licenses, if the release of articles and information on the mobile applications and the websites autohome.com.cn and che168.com is deemed by the PRC regulatory authorities as being provision of internet publishing service, internet news information service. See "Item 4. Information on the Company-B. Business Overview-PRC Regulation-Regulations on Internet Publishing" and "Item 4. Information on the Company-B. Business Overview-PRC Regulation-Regulations on Internet News Information Service" for additional details. -   The evolving PRC regulatory system for the internet industry may lead to the establishment of new regulatory agencies. For example, the Cyberspace Administration of China was established in 2014, as the central Internet censorship, oversight and control agency for the PRC. -   New laws and regulations may be promulgated to regulate internet activities, including online advertising businesses and online auto finance businesses. As such, additional licenses may be required for our operations. If our operations do not comply with these new regulations at the time they become effective, or if we fail to obtain any licenses required under these new laws and regulations, we could be subject to penalties. -   New government policies and internal rules relating to the regulations on internet activities may negatively affect our user traffic growth. For example, the E-commerce Law, which took effect on January 1, 2019, provides that the character "advertisement" should be noticeably marked on the commodities or services ranked under competitive bidding. Complying with such requirements may negatively affect the growth rate of user traffic on our websites and mobile applications. The promulgation of laws and regulations relating to the internet activities may further impair our user traffic growth. On July 13, 2006, the MIIT, the predecessor of which was the Ministry of Information Industry, issued the Notice of the Ministry of Information Industry on Intensifying the Administration of Foreign Investment in Value-added Telecommunications Services. This notice prohibits domestic telecommunication service providers from leasing, transferring or selling telecommunications business operating licenses to any foreign investor in any form, or providing any resources, sites or facilities to any foreign investor for their illegal operation of a telecommunications business in China. According to this notice, either the holder of a value-added telecommunication services operation permit or its shareholders must directly own the domain names and trademarks used by such license holders in their provision of value-added telecommunication services. The notice also requires each license holder to have the necessary facilities, including servers, for its approved business operations and to maintain such facilities in the regions covered by its license. Currently, Autohome Information and Shengtuo Hongyuan, two of our VIEs, own the related domain names and trademarks and hold the internet content provider licenses, or ICP licenses, necessary to conduct our operations for websites and mobile applications in China. The interpretation and application of existing PRC laws, regulations and policies and possible new laws, regulations or policies relating to the internet industry have created substantial uncertainties regarding the legality of existing and future foreign investments in, and the businesses and activities of, internet businesses in China, including our business. We cannot assure you that we will be able to maintain our existing licenses or obtain any new licenses if required by any new laws or regulations. There are also risks that we may be found to violate existing or future laws and regulations given the uncertainty and complexity of China's regulation of the internet industry. If we or our VIEs fail to obtain or maintain any of the required assets, licenses or approvals, our continued business operations in the internet industry may subject us to various penalties, including the confiscation of illegal net revenues, fines and the discontinuation or restriction of our operations, any of which would materially and adversely affect our business and results of operations.

We conduct our business primarily through our PRC subsidiaries and VIEs in China. Our operations in China are governed by PRC laws and regulations. Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us. In 1979, the PRC government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation over the past several decades has significantly enhanced the protections afforded to various forms of foreign investments in China. However, China has not developed a fully integrated legal system, and recently enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. In particular, because these laws and regulations are relatively new, and because of the limited volume of published decisions and their nonbinding nature, the interpretation and enforcement of these laws and regulations involve uncertainties. Since PRC administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy. Furthermore, the PRC legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, which may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until sometime after the violation. In addition, any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention.

In December 2006, the People's Bank of China, or PBOC, promulgated the Administrative Measures of Foreign Exchange Matters for Individuals, which sets forth the respective requirements for foreign exchange transactions by individuals (both PRC and non-PRC citizens) under either the current account or the capital account. In January 2007, SAFE issued relevant implementing rules which were further revised by SAFE Circular 13 in 2016, that specified approval requirements for certain capital account transactions such as a PRC citizen's participation in the employee stock incentive plans or share option plans of an overseas publicly listed company. In February 2012, SAFE promulgated the Notice on the Administration of Foreign Exchange Matters for Domestic Individuals Participating in the Stock Incentive Plans of Overseas Listed Companies, or the Stock Option Notice. The Stock Option Notice supersedes the requirements and procedures for the registration of PRC resident individuals' participation in stock incentive plans set forth by certain rules promulgated by SAFE in March 2007. Under these measures, PRC resident individuals who participate in an employee stock incentive plan or a share option plan in an overseas publicly listed company are required to register with SAFE and complete certain other procedures. A PRC domestic qualified agent appointed through the PRC subsidiaries of such overseas listed company must file applications on behalf of such PRC resident individuals with SAFE or its local counterpart to obtain approval for an annual allowance with respect to the foreign exchange in connection with stock holding or share option exercises. With the approval from SAFE or its local counterpart, the PRC domestic qualified agent must open a special foreign exchange account at a PRC domestic bank to hold the funds required in connection with the stock purchase or option exercise, payment received upon sales of shares, dividends issued on the stock and any other income or expenditures approved by SAFE or its local counterpart. We and our PRC resident employees who participate in our share incentive plans are subject to these regulations as we are an overseas listed company. We have made registration with the local counterparts of SAFE for our PRC resident employees who participate in our share incentive plans as required under the Stock Option notice and relevant rules. If we or our PRC plan participants fail to comply with these regulations, we or our PRC plan participants may be subject to fines and other legal or administrative sanctions. See "Item 4. Information on the Company-B. Business Overview-PRC Regulation-Regulations on Employee Stock Options Plans."

We may be subject to claims, suits, and government investigations involving competition, intellectual property, privacy, consumer protection, tax, labor and employment, commercial disputes, advertisements and content placed on our websites and mobile applications, and other matters. Our business may also face intellectual property infringement claims, as further discussed elsewhere in this annual report, that expose us to the risk of reputation damage. Such claims, suits, and government investigations are inherently uncertain and their results cannot be predicted with certainty. Regardless of the outcome, any of these types of legal proceedings can have an adverse impact on us due to the legal costs, diversion of management resources, negative publicity and other factors involved therein. It is possible that one or more of such proceedings could result in substantial fines and penalties that could adversely affect our business.

Under United States federal income tax law, we will be classified as a passive foreign investment company ("PFIC") for any taxable year if either (i) at least 75% of our gross income for the taxable year is passive income or (ii) at least 50% of the value of our assets (based on the average quarterly value of our assets during the taxable year) is attributable to assets that produce or are held for the production of passive income (the "asset test"). Although the law in this regard is not entirely clear, we treat our VIEs as being owned by us for United States federal income tax purposes because we control their management decisions and are entitled to substantially all of the economic benefits associated with such entities, and, as a result, we consolidate their results of operations in our consolidated U.S. GAAP financial statements. Assuming we are the owner of our VIEs for U.S. federal income tax purposes and based on our current income and assets, including goodwill and unbooked intangibles, we do not believe that we were a PFIC for the taxable year ended December 31, 2018 and do not anticipate becoming a PFIC in future taxable years. While we do not believe that we were a PFIC for the taxable year ended December 31, 2018 and do not anticipate becoming a PFIC in the foreseeable future, no assurance can be given in this regard because the determination of whether we will be or become a PFIC is a fact-intensive inquiry made on an annual basis that depends, in part, on the composition of our income and assets. Fluctuations in the market price of our ADSs may cause us to become a PFIC for the current or subsequent taxable years because the value of assets for the purpose of the asset test may be determined by reference to the market price of our ADSs from time to time (which may be volatile). The composition of our income and assets may also be affected by how, and how quickly, we use our liquid assets. Under circumstances where our revenue from activities that produce passive income significantly increase relative to our revenue from activities that produce non-passive income, or where we determine not to deploy significant amounts of cash for active purposes, our risk of becoming classified as a PFIC may substantially increase. In addition, because there are uncertainties in the application of the relevant rules, it is possible that the Internal Revenue Service may challenge our classification of certain income and assets as non-passive or our valuation of our tangible and intangible assets, each of which may result in us becoming a PFIC for the current or subsequent taxable years. If we were to be or become a PFIC, a U.S. Holder (as defined in "Item 10. Additional Information-E. Taxation-United States Federal Income Tax Considerations-General") may incur significantly increased United States income tax on gains recognized on the sale or other disposition of the ADSs or Class A ordinary shares and on the receipt of distributions on the ADSs or Class A ordinary shares to the extent such gain or distribution is treated as an "excess distribution" under United States federal income tax rules. Further, if we were a PFIC for any year during which a U.S. Holder held our ADSs or Class A ordinary shares, we generally would continue to be treated as a PFIC as to such U.S. Holder for all succeeding years during which such U.S. Holder held our ADSs or Class A ordinary shares. Alternatively, U.S. Holders of PFIC shares can sometimes avoid the rules described above by making certain elections, including a "mark-to-market" election or electing to treat a PFIC as a "qualified electing fund." However, U.S. Holders will not be able to make an election to treat us as a "qualified electing fund" because, even if we were to be or become a PFIC, we do not intend to comply with the requirements necessary to permit U.S. Holders to make such election. Each U.S. Holder is urged to consult its tax advisor concerning the United States federal income tax consequences of owning and disposing of ADSs or Class A ordinary shares if we were to be or become a PFIC. For more information, see "Item 10. Additional Information-E. Taxation-United States Federal Income Tax Considerations-Passive Foreign Investment Company Rules."

Under the Enterprise Income Tax Law, which became effective on January 1, 2008 and was amended on February 24, 2017, and its implementation rules, which became effective on January 1, 2008, an enterprise established outside of the PRC with "de facto management bodies" within the PRC is considered a resident enterprise and will be subject to the enterprise income tax at the rate of 25% on its global income. The SAT issued the Notice Regarding the Determination of Chinese-Controlled Offshore Incorporated Enterprises as PRC Tax Resident Enterprises on the Basis of De Facto Management Bodies, or SAT Circular 82, on April 22, 2009, which was amended in 2013 and 2017 respectively. SAT Circular 82 provides certain specific criteria for determining whether the "de facto management body" of a Chinese-controlled offshore-incorporated enterprise is located in China. Although we do not believe that our legal entities organized outside of the PRC constitute PRC resident enterprises, it is possible that the PRC tax authorities could reach a different conclusion. In such case, we may be considered a PRC resident enterprise and may therefore be subject to enterprise income tax at a rate of 25% on our global income. If we are considered a PRC resident enterprise and earn income other than dividends from our PRC subsidiaries, a 25% enterprise income tax on our global income could significantly increase our tax burden and materially and adversely affect our cash flow and profitability. Pursuant to the amended Enterprise Income Tax Law and its implementation rules, dividends generated after January 1, 2008 and payable by a foreign-invested enterprise in China to its foreign investors, which are non-PRC tax resident enterprises without an establishment in China, or whose income has no connection with their institutions and establishments inside China, are subject to withholding tax at a rate of 10%, unless any such foreign investor's jurisdiction of incorporation has a tax treaty with China that provides for a different withholding arrangement. We are a Cayman Islands holding company and we conduct our business through our wholly-owned subsidiaries and VIEs in the PRC, of which Autohome WFOE and Chezhiying WFOE are the primary beneficiaries of our VIEs. Autohome WFOE is 100% owned by Cheerbright International Limited, or Cheerbright, our wholly owned subsidiary located in the British Virgin Islands. The British Virgin Islands currently does not have any tax treaty with China with respect to withholding tax. As long as Cheerbright is considered a non-PRC resident enterprise, dividends that it receives from Autohome WFOE may be subject to withholding tax at a rate of 10%. As to our subsidiaries located in Hong Kong, such as Autohome Media, the shareholder of our PRC subsidiaries currently engaging in advertising business, and Autohome Link Hong Kong Limited, the shareholder of Chezhiying WFOE, under the Arrangement between the PRC and the Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion, effective on January 1, 2007, as long as each of our Hong Kong subsidiaries is considered a non-PRC resident enterprise and directly holds at least 25% of the equity interests of its respective PRC subsidiaries, dividends that it receives from its PRC subsidiaries may be subject to withholding tax at a preferential rate of 5%, if it is the beneficial owner of the dividends, upon receiving the approval from the local tax authority. In August 2015, the State Administration of Taxation promulgated the Administrative Measures for Non-Resident Taxpayers to Enjoy Treatments under Tax Treaties, or SAT Circular 60, which became effective on November 1, 2015. SAT 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 upon their 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-filing examinations by the relevant tax authorities. As uncertainties remain regarding the interpretation and implementation of the amended Enterprise Income Tax Law and its implementation rules, we cannot assure you that if we are regarded as a PRC resident enterprise, any dividends to be distributed by us to our non-PRC enterprise shareholders and ADS holders would not be subject to any PRC withholding tax at a rate of 10% and to non-PRC individual shareholders and ADS holders would not be subject to PRC individual income tax at a rate of 20%. Similarly, any gain recognized by such non-PRC shareholders or ADS holders on the sale of shares or ADSs, as applicable, may also be subject to PRC tax. If our dividends payable to our non-PRC enterprise shareholders, non-PRC individual shareholders and ADS holders, or on gains recognized by such non-PRC shareholders or ADS holders are required under the Enterprise Income Tax Law and the Individual Income Tax Law to be subject to PRC tax, such investors' investment in our Class A ordinary shares or ADSs may be materially and adversely affected.

With the continuous growth of internet usage in China, the internet has become an increasingly important marketing and advertising channel to China's automotive industry. Although online advertising and promotion have constituted a significant portion of the overall marketing activities of our current and potential advertisers and dealer subscribers, if the promotional effect or outcome realized through online advertising and promotion cannot meet the expectations of advertisers and dealer subscribers or address their needs, our advertisers and dealer subscribers may decrease their spending and efforts on online advertising and promotion and devote more marketing budgets to traditional print and broadcast media. Our ability to increase revenue and profitability from online marketing may be adversely impacted by a number of factors, many of which are beyond our control, including: -   difficulties associated with developing a larger user base with demographic characteristics attractive to advertisers;-   increased competition and potential downward pressure on online advertising prices;-   difficulties in acquiring and retaining advertisers or dealer subscribers;-   uncertainties and changes in regards to PRC regulations on internet advertisements;-   failure to develop an independent and reliable means of verifying online traffic; and -   decreased use of the internet or online marketing in China. If the internet does not become more widely accepted as an effective media platform for advertising and marketing by China's automotive industry, our business, financial condition and results of operations could be materially and adversely affected.

In order to maintain and strengthen our position as a leading online destination for automobile consumers in China, we must continue to attract and retain users to our websites and mobile applications, which requires us to continue to provide quality content throughout the automobile ownership life cycles. We must also innovate and introduce services and applications that enhance user experience. In addition, we must maintain and enhance our brand recognition among consumers. If we fail to provide high-quality, enriched and customized content, offer a superior user experience or maintain and enhance our brand recognition, we may not be able to attract and retain users. Also, the user experience we offer to automobile consumers may be negatively affected by the non-automobile advertisements displayed on our websites and applications. If our user base decreases, our websites and mobile applications may be rendered less attractive to customers, including automakers and dealers, and our services may become less attractive, which may have a material and adverse impact on our business, financial condition and results of operations.

We have incurred expenses on a variety of marketing and brand promotion efforts designed to enhance our brand recognition and increase sales of our products and services. Our marketing and promotional activities may not be well received by customers and may not result in the level of sales of products and services that we anticipate. We incurred RMB1,536.9 million, RMB1,647.5 million and RMB2,435.2 million (US$354.2 million) in sales and marketing expenses in 2016, 2017 and 2018, respectively, representing 28.8%, 29.2% and 33.6%, respectively, of total net revenues in the corresponding years. Marketing approaches and tools in the consumer products market in China are evolving. This further requires us to enhance our marketing approaches and experiment with new marketing methods to keep pace with industry developments and consumer preferences, which may not be as cost-effective as our marketing activities in the past and may lead to significantly higher marketing expenses in the future. We conducted various sales and marketing initiatives to promote our brands through websites, search engines, mobile platforms, navigation sites and traditional media channels, for example, the annual "Singles' Day" event, the "AR Auto Show" event and TV ad broadcast on China Central Television. We also conducted various offline promotional activities and cooperated with brands and dealers for promotions in target regions. We may not be able to continue or conduct these activities efficiently, and our marketing activities may not yield satisfactory results. Failure to refine our existing marketing approaches or to introduce new effective marketing approaches in a cost-effective manner could impact our net revenues and profitability.

Although we consider automakers and automobile dealers to be our end-customers for our media services and have been prioritizing the direct cooperation with the automaker advertisers on ad placement since 2018, we are currently selling a substantial portion of our advertising services and solutions to third-party advertising agencies that represent the automakers and automobile dealers, who could maintain our business relationships with automakers and automobile dealers. We do not have long-term cooperation agreements or exclusive arrangements with these agencies and they may elect to direct business to other advertising service providers, including our competitors. If we fail to retain and enhance our business relationships with third-party advertising agencies, in particular the few ones we frequently transact with, we may suffer from a loss of advertisers and our business, financial condition, results of operations and prospects may be materially and adversely affected. In our agreements with certain major advertising agencies, we undertake to provide them with most favored pricing terms. Such most favored pricing terms may hinder our ability to acquire new customers using special pricing terms. In addition, we have been relying on third-party advertising agencies for the collection of payment from advertisers and we have been relying on a few advertising agencies to collect a significant portion of our total account receivables. As a result, the financial soundness of advertising agencies may affect our collection of accounts receivable. We make a credit assessment of a potential advertising agency to evaluate the collectability of the advertising service fees before entering into an advertising contract. However, we cannot assure you that we will be able to accurately assess the creditworthiness of each advertising agency, and any failure of advertising agencies to pay us in a timely manner may adversely affect our liquidity and cash flows. Initiating legal proceedings against such advertising agencies can be expensive and time-consuming, and could divert our management's attention and other resources from our business operations, which could adversely affect our results of operations. Even if we receive a favorable judgment in such legal proceedings, it may still be challenging and uncertain for us to collect the outstanding payments promptly and in full from the advertising agencies if they are experiencing financial difficulties.

Our automobile listings and promotional information are provided and updated by third parties on our platform, including the automakers, dealers, independent automobile sellers, financial partners and used car sellers. Users interested in particular vehicle models can conveniently search for up-to-date information on such models without having to visit the local showrooms of relevant dealers or solicit related information from other sources. Although we have optimized our system to detect pricing inaccuracy and have leveraged our advanced technology and third-party data to improve the accuracy of price listings and promotional information on our platform, we cannot assure you that these measures are always effective to ensure the accuracy and reliability of pricing and listing information provided to our users. If such listings and promotional information provided by the third parties on our platform are frequently inaccurate or not reliable, our users may lose faith in our websites and mobile applications, resulting in reduced user traffic to our websites and mobile applications and diminished value to advertisers. We may receive more customer complaints, and we may need to allocate more resources in responding and handling such complaints. We cannot guarantee that such complaints will be resolved in satisfactory outcome. Our reputation could be harmed, which could adversely affect our business and financial performance.

One element of our growth strategy is to expand our services to customers. As a result, we have added additional services in the past few years. To serve our dealer customers, we had local sales and service representatives covering 192 cities across China as of December 31, 2018. We intend to increase our penetration in existing dealer advertising and subscription services markets. We have implemented business strategies to further monetize our large dealer network by enlarging the offering of products and services with new technologies on our dealer digital platform, increasing the average spending of our existing dealer subscribers and upselling our dealership packages for our leads generation services. In order to increase the average spending of our existing dealer subscribers, we keep close communications and negotiations with relevant parties such as dealers, dealers group and automakers. However, we may not succeed in making our customers sufficiently aware of existing and future services or in creating customer acceptance of these services at the prices we would want to charge, and we cannot guarantee that our pricing strategy and measures will always be agreed and accepted by any and all of our customers. We may not be able to achieve the market acceptance of our products and services as we expect and thus may fail to achieve an increase from our "share of wallet" approach. Our existing customers may even terminate their cooperation with us if they are not satisfied with our pricing strategy or measures, which may subject us to negative publicity and adversely impact our business. Also, we may not identify trends correctly, or may not be able to bring new services to market as quickly, effectively or price-competitively as our competitors. New services may alienate existing customers or cause us to lose business to our competitors. If the number of our dealer customers decreases, we will not be able to generate sufficient revenues to cover our increased costs and expenses. As a result, our business and results of operations may be materially and adversely affected.

Internet, technology and media companies are frequently involved in litigation based on allegations of infringement of intellectual property rights, unfair competition, invasion of privacy, defamation and other violation of other parties' rights. We have not experienced any material claims on these issues against us in the past, but as we face increasing competition and as litigation becomes more common in China in resolving commercial disputes, we face a higher risk of being the subject of intellectual property infringement claims. Also, third parties may submit intellectual property infringement claims against us to the app stores where our mobile applications are available. In such cases, our mobile applications may be taken down by the relevant app stores until such claims have been resolved, which could significantly restrict our users from downloading or updating our mobile applications and thus adversely affect our business and results of operations. In addition, we may be subject to legal proceedings and claims from time to time relating to the intellectual property of others in the ordinary course of our business. We could also be subject to claims based upon the content that is displayed on our websites, our mobile platforms or accessible from our websites through links to other websites or information on our websites and mobile applications supplied by third parties. Intellectual property claims and litigation are expensive and time-consuming to investigate and defend and may divert resources and management attention from the operation of our websites and mobile applications. Such claims, even if they do not result in liability, may harm our reputation. Any resulting liability or expenses, or changes required to our websites and mobile applications to reduce the risk of future liability, may have a material adverse effect on our business, financial condition and results of operations.
