Exchange Rate Information

Our business is primarily conducted in China and almost all of our revenues are denominated in RMB. However, periodic reports made to shareholders will include current period amounts translated into U.S. dollars using the then current exchange rates, for the convenience of the readers. The conversion of RMB into U.S. dollars in this annual report is based on the noon buying rate in New York City for cable transfers in RMB as certified for customs purposes by the Federal Reserve Board. Unless otherwise noted, all translations from RMB to U.S. dollars and from U.S. dollars to RMB in this annual report were made at a rate of RMB6.0537 to US$1.00, the noon buying rate in effect as of December 31, 2013. 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 March 21, 2014, the noon buying rate was RMB6.2248 to US$1.00.

Risks Related to Our Business

If we fail to retain existing customers or attract new customers for our online marketing services, our business, results of operations and growth prospects could be seriously harmed.

We generate substantially all of our revenues from online marketing services, a substantial majority of which are derived from our pay-for-performance, or P4P, services. Our online marketing customers will not continue to do business with us if their investment does not generate sales leads and ultimately consumers, or if we do not deliver their web pages in an appropriate and effective manner. Our P4P customers may discontinue their business with us at any time and for any reason as they are not subject to fixed-term contracts. We have in the past removed, and may in the future again remove, questionable paid search listings of some customers to ensure the quality and reliability of our search results. Such removal, whether temporary or permanent, may cause the affected customers to discontinue their business with us. In addition, third parties may develop and use certain technologies to block the display of our customers’ advertisements and other marketing products on our Baidu.com website, which may in turn cause us to lose customers and adversely affect our results of operations. Furthermore, we adjust prices for our online marketing services from time to time. We may lose customers who decide not to pay our increased prices. Failure to retain our existing customers or attract new customers for our online marketing services could seriously harm our business, results of operations and growth prospects.

In recent years, we have generated an increasing amount of online marketing revenues from online advertising. We believe our large user base and traffic provide advertisers with a broad reach and optimal monetization results. However, we cannot assure you that we will be able to continue to attract new advertisers or retain our existing advertisers. If our advertisers determine that their expenditures on our websites do not generate expected returns, they may allocate a portion or all of their advertising budgets to other advertising channels such as television and outdoor media and reduce or discontinue business with us. Since most of our advertisers are not bound by long-term contracts, they may amend or terminate advertising arrangements with us easily without incurring liabilities. Failure to retain existing advertisers or attract new ones to advertise on our websites may materially and adversely affect our business, financial condition, results of operations and prospects.

If online marketing does not further grow in China, our ability to increase revenue and profitability could be materially and adversely affected.

The use of the internet as a marketing channel is at a developing stage in China. Internet penetration rate in China is relatively low as compared to that in most developed countries. Many of our current and potential customers have limited experience with the internet as a marketing channel, and historically have not devoted a significant portion of their marketing budgets to online marketing and promotion. As a result, they may not consider the internet to be an effective channel to promote their products and services as compared 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 online marketing customers;

| • |  | increased competition and potential downward pressure on online marketing prices;

| • |  | higher customer acquisition costs due in part to the limited experience of small to medium-sized enterprises, or SMEs, with the internet as a marketing channel;

| • |  | failure to develop an independent and reliable means of verifying online traffic;

| • |  | ineffectiveness of our online marketing delivery, tracking and reporting systems; and

| • |  | decreased use of internet or online marketing in China.

Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our business and results of operations may be harmed.

We believe that our brand “Baidu” has contributed significantly to the success of our business. We also believe that maintaining and enhancing the “Baidu” brand is critical to increasing the number of our users, customers and Baidu Union members. We have conducted various marketing and brand promotion activities, but we cannot assure you that these activities will achieve the brand promotion effect expected by us. If we fail to maintain and further promote the “Baidu” brand, or if we incur excessive expenses in this effort, our business and results of operations may be materially and adversely affected. In addition, any negative publicity about our company, our products and services, our employees, our business practices, or our search results or the websites to which our search results link, regardless of its veracity, could harm our brand image and in turn adversely affect our business and results of operations.

We face significant competition and may suffer from loss of users and customers as a result.

We face significant competition in almost every aspect of our business, particularly from other companies that seek to provide internet search services to users and provide online marketing services to customers. In the Chinese internet search market, our main competitors include U.S.-based internet search providers providing Chinese language internet search services, such as Google, and China-based internet companies, such as Sogou,

6

##### Table of Contents

Alibaba and Qihoo 360. We compete with these entities for both users and customers on the basis of user traffic, quality (relevance), safety and user experience of the search results, availability and ease of use of products and services, the number of customers, distribution channels and the number of associated third-party websites. Some of our competitors have significant financial resources, long operating histories and are experienced in attracting and retaining users and managing customers. They may use their experience and resources to compete with us in a variety of ways, including by competing more heavily for users, customers, distributors, strategic partners and networks of third-party websites, investing more heavily in research and development and making acquisitions. If any of our competitors provides comparable or better Chinese language search experience, our user traffic could decline significantly. Any such decline in traffic could weaken our brand and result in loss of users and customers, which would have a material and adverse effect on our results of operations.

We also face competition from other types of advertising media, such as newspapers, magazines, yellow pages, billboards, other forms of outdoor media, television, radio and mobile applications. Large companies in China generally allocate, and may continue to allocate, most of their marketing budgets to traditional advertising media and only a small portion of their budgets to online marketing and other forms of advertising media. If these companies do not devote a larger portion of their marketing budgets to online marketing services provided by us, or if our existing customers reduce the amount they spend on online marketing, our results of operations and growth prospects could be adversely affected.

If our expansions into new internet businesses are not successful, our future results of operations and growth prospects may be materially and adversely affected.

As part of our growth strategy, we enter into new internet businesses from time to time by leveraging our large internet search user base to generate additional revenue streams and through our development of new business lines or strategic investments in or acquisitions of other businesses. Expansions into new businesses may present operating and marketing challenges that are different from those that we currently encounter. For each new business we enter into, we face competition from existing leading players in that business. If we cannot successfully address the new challenges and compete effectively against the existing leading players in the new businesses, we may not be able to develop a sufficiently large customer and user base, recover costs incurred for investing in, developing and marketing new businesses, and eventually achieve profitability from these businesses, and our future results of operations and growth prospects may be materially and adversely affected.

If we fail to continue to innovate and provide products and services to attract and retain users, we may not be able to generate sufficient user traffic levels to remain competitive.

Our success depends on providing products and services to attract users and enable users to have a high-quality internet experience. In order to attract and retain users and compete against our competitors, we must continue to invest significant resources in research and development to enhance our internet search technology, improve our existing products and services and introduce additional high-quality products and services. If we are unable to anticipate user preferences or industry changes, or if we are unable to modify our products and services on a timely basis, we may lose users. Our results of operations may also suffer if our innovations do not respond to the needs of our users, are not appropriately timed with market opportunities or are not effectively brought to market. As search technology continues to develop and mobile devices and applications are increasingly used to access the internet, our competitors may be able to offer products and services that are, or that are perceived to be, substantially similar to or better than those provided by us. This may force us to expend significant resources in research and development and strategic investments and acquisitions in order to remain competitive.

If we fail to keep up with rapid changes in technologies and user behavior, our future success may be adversely affected.

Our future success will depend on our ability to respond to rapidly changing technologies, adapt our products and services to evolving industry standards and improve the performance and reliability of our products

##### Table of Contents

and services. Our failure to adapt to such changes could harm our business. In addition, changes in user behavior resulting from technological developments may also adversely affect us. For example, the number of people accessing the internet through mobile devices, including mobile phones, tablets and other hand-held devices, has increased in recent years, and we expect this trend to continue while 3G and more advanced mobile communications technologies are broadly implemented. If we fail to develop products and technologies that are compatible with all mobile devices and operating systems, or if the products and services we develop are not widely accepted and used by users of various mobile devices and operating systems, we may not be able to penetrate the mobile internet market. In addition, the widespread adoption of new internet, networking or telecommunications technologies or other technological changes could require substantial expenditures to modify or integrate our products, services or infrastructure. If we fail to keep up with rapid technological changes to remain competitive, our future success may be adversely affected.

Interruption or failure of our own information technology and communications systems or those of third-party service providers we rely upon could impair our ability to provide products and services, which could damage our reputation and harm our results of operations.

Our ability to provide products and services depends on the continuing operation of our information technology and communications systems. Any damage to or failure of our systems could interrupt our services. Service interruptions could reduce our revenues and profits and damage our brand if our systems are perceived to be unreliable. Our systems are vulnerable to damage or interruption as a result of terrorist attacks, wars, earthquakes, floods, fires, power loss, telecommunications failures, undetected errors or “bugs” in our software, computer viruses, interruptions in access to our websites through the use of “denial of service” or similar attacks, hacking or other attempts to harm our systems, and similar events. Some of our systems are not fully redundant, and our disaster recovery planning does not account for all possible scenarios. In September 2013, the service of our Baidu Post Bar was inaccessible to many users for over four hours due to a failure of the internet infrastructure in Beijing.

Our servers, which are hosted at third-party or our own internet data centers, are vulnerable to break-ins, sabotage and vandalism. The occurrence of natural disaster or closure of an internet data center by a third-party provider without adequate notice could result in lengthy service interruptions. In addition, our domain names are resolved into internet protocol (IP) addresses by systems of third-party domain name registrars and registries. Any interruptions or failures of those service providers’ systems, which are beyond our control, could significantly disrupt our own services. If we experience frequent or persistent system failures on our websites, whether due to interruptions and failures of our own information technology and communications systems or those of third-party service providers we rely upon, our reputation and brand could be severely harmed. The steps we take to increase the reliability and redundancy of our systems are expensive, may reduce our operating margin and may not be successful in reducing the frequency or duration of service interruptions.

We may not be able to manage our expanding operations effectively.

We have significantly expanded our operations in recent years. We expect this expansion trend to continue as we grow our user and customer base and explore new opportunities. To manage the further expansion of our business and growth of our operations and personnel, we need to continually improve our operational and financial systems, procedures and controls, and expand, train, manage and maintain good relations with, our growing employee base. We have experienced labor disputes in the past. Although these disputes were resolved promptly, we cannot assure you that there will not be any new labor dispute in the future. In addition, we must maintain and expand our relationships with other websites, internet companies and other third parties. Our current and future personnel, systems, procedures and controls may not be adequate to support our expanding operations.

We may face intellectual property infringement claims and other related claims that could be time-consuming and costly to defend and may result in an adverse impact over our operations.

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 violations of other parties’ rights. The validity, enforceability and scope of protection of intellectual property in internet-related industries, particularly in China, are uncertain and still evolving. 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. We may be subject to administrative actions brought by the PRC State Copyright Bureau, and in the most severe scenario criminal prosecution, for alleged copyright infringement, and as a result may be subject to fines and other penalties and be required to discontinue infringing activities. Furthermore, as we expand our operations outside of China, we may be subject to claims brought against us in jurisdictions outside of China.

Our search products and services, such as Baidu Video Search, link to materials in which third parties may claim ownership of trademarks, copyrights or other rights. Our audio and video player, Baidu Media Player, enables users to play multimedia files, which may be protected by copyright or other intellectual property rights. In addition, as we adopt new technologies and roll out new products and services, we face the risk of being subject to intellectual property infringement claims that may arise from our use of new technologies and provision of new products and services. Our products and services including those based on cloud computing technology, such as Baidu WenKu and Baidu Post Bar, allow our users to upload written materials and pictures to our servers, or share, link to or otherwise provide access to audio, video and other contents from other websites, and we also operate distribution platforms whereby developers can upload, share and sell their applications or games to users. Although we have made commercially reasonable efforts to request all of our users or developers to comply with applicable intellectual property laws, we cannot ensure that all of our users or developers have the rights to upload or share these contents or applications. In addition, we have been and may continue to be subject to copyright or trademark infringement and other related claims from time to time, in China and internationally.

We have been making continuous efforts to keep ourselves informed of and to comply with all applicable laws and regulations affecting our business. However, PRC laws and regulations are evolving, and uncertainties still exist with respect to the legal standards as well as the judicial interpretation of the standards for determining liabilities of internet search and other internet service providers for providing links to contents on third-party websites that infringe upon others’ copyrights or hosting such contents, or providing information storage space, file sharing technology or other internet services that are used by internet users to disseminate such contents. The Supreme People’s Court of China promulgated a judicial interpretation on infringement of the right of dissemination through internet in December 2012. This judicial interpretation, like certain court rulings and certain other judicial interpretations, provide that the courts will place the burden on internet service providers to remove not only links or contents that have been specifically mentioned in the notices of infringement from right holders, but also links or contents they “should have known” to contain infringing content. The interpretation further provides that where an internet service provider has directly obtained economic benefits from any contents made available by an internet user, it has a higher duty of care with respect to internet users’ infringement of third-party copyrights. A guidance on the trial of audio/video sharing copyright disputes promulgated by the Higher People’s Court of Beijing in December 2012 provides that where an internet service provider has directly obtained economic benefits from any audio/video contents made available by an internet user who has no authorization for sharing such contents, the internet service provider shall be presumed to be at fault. These interpretations could subject us and other internet service providers to significant administrative burdens and litigation risks.

We conduct our business operations primarily in China. There might be claims that we are subject to U.S. copyright laws, including the legal standards for determining indirect liability for copyright infringement, although we believe such claims are without merits. We cannot assure you that we will not be subject to copyright infringement lawsuits or other proceedings in the U.S. or elsewhere in the future.

Intellectual property litigation is expensive and time-consuming and could divert resources and management attention from the operations of our business. We are currently named as a defendant in some copyright infringement suits in connection with our Baidu WenKu, Baidu Post Bar, Baidu Media Player, Baidu Video Search, iQiyi and certain other products or services. See “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings.” There is no guarantee that the competent courts will accept our defenses and rule in our favor. If there is a successful claim of infringement, we may be required to discontinue the infringing activities, pay substantial fines and damages and/or enter into royalty or license agreements that may not be available on commercially acceptable terms, if at all. Our failure to obtain a license of the rights on a timely basis could harm our business. Any intellectual property litigation by third parties and/or negative publicity alleging our intellectual property infringement could have an adverse effect on our business, reputation, financial condition or results of operations. To address the risks relating to intellectual property infringement, we may have to substantially modify, limit or terminate some of our search services. Any such change could materially affect user experience and in turn have an adverse impact on our business.

We have been and may again be subject to claims based on the content found on our websites or the results in our paid search listings.

In addition to the content developed by ourselves and posted on our websites, our users are free to post information on Baidu Post Bar, Baidu Knows, Baidu Encyclopedia, Baidu WenKu and other sections of our websites, and our P4P customers may create text-based descriptions, image descriptions and other phrases to be used as text, image or keywords in our search listings. We have been and may continue to be subject to claims for defamation, negligence or other legal theories based on the content found on our websites, which, with or without merit, may result in diversion of management attention and financial resources and negative publicity on our brand and reputation. See “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings.” Furthermore, if the content posted on our websites contains information that government authorities find objectionable, our websites may be shut down and we may be subject to other penalties. See “—Risks Related to Doing Business in China—Regulation and censorship of information disseminated over the internet in China may adversely affect our business, and subject us to liability for information displayed on or linked to our websites, and negative publicity in international media.”

Under PRC advertising laws and regulations, we are obligated to monitor the advertising content posted on our websites to ensure that such content is fair and accurate and in compliance with applicable law. In addition, where a special government review is required for specific categories of advertisements before posting, we are obligated to confirm that such review has been performed and approval has been obtained. See “Item 4.B. Information on the Company—Business Overview—Regulation—Regulations on Advertisements.” Our P4P services are not subject to PRC advertising laws and regulations, because PRC laws and regulations and administrative authorities currently do not classify P4P services as a form of online advertising. However, if P4P services are classified as a form of online advertising in the future, we would be obligated to examine the content of our P4P customers’ listings on our websites as required by PRC advertising laws and regulations, which could be very burdensome, and we may have to stop posting certain categories of listings on our websites or otherwise cease our P4P services for certain categories of customers. If advertisements shown on our websites are in violation of relevant PRC advertising laws and regulations, or if the supporting documentation and government approvals provided to us by our advertising clients in connection with the advertising content are not complete or accurate, we may be subject to legal liabilities and our reputation could be harmed.

We have been and in the future may again be subject to claims or negative publicity based on the results in our paid search listings. Claims have been filed against us after we allowed certain customers to register keywords containing trademarks, trade names or brand names owned by others and displayed links to such customers’ websites in our paid search listings. While we maintain a database of certain well-known trademarks and update continually our system algorithms and functions aiming at preventing customers from submitting a keyword containing the well-known trademarks that we know are owned by others, it is not possible for us to completely prevent our customers from bidding on keywords that contain trademarks, trade names or brand

##### Table of Contents

names owned by others. There has been negative publicity about fraudulent information in our paid search listings. Although we have been continually enhancing our technology, control and oversight to prevent fraudulent websites, web pages and information from our paid search listings, there is no guarantee that the measures we have taken are effective at all times. Claims and negative publicity based on the results in our paid search listings, regardless of their merit, may divert management attention, severely disrupt our operations, adversely affect our results of operations and harm our reputation.

We may be subject to patent infringement claims with respect to our P4P platform.

Our technologies and business methods, including those relating to our P4P platform, may be subject to third-party claims or rights that limit or prevent their use. In June 2005, we applied for a patent in China for our P4P platform, but our application was rejected on the ground that it is not patentable. Certain U.S.-based companies, including Overture Services Inc., have been granted patents in the United States relating to P4P platforms and similar business methods and related technologies. While we believe that we are not subject to U.S. patent laws since we conduct our business operations outside of the United States, we cannot assure you that U.S. patent laws would not be applicable to our business operations, or that holders of patents relating to a P4P platform would not seek to enforce such patents against us in the United States or China.

Many parties are actively developing and seeking protection for internet-related technologies, including patent protection. They may hold patents issued or pending that relate to certain aspects of our technologies, products, business methods or services. Any patent infringement claims, regardless of their merits, could be time-consuming and costly to us. If we were sued for patent infringement claims with respect to our P4P platform and were found to infringe upon the patents and were not able to adopt non-infringing technologies, we may be severely limited in our ability to operate our P4P platform, which would have a material and adverse effect on our results of operations and prospects.

Our business may be adversely affected by third-party software applications or practices that interfere with our receipt of information from, or provision of information to, our users, which may impair our users’ experience.

Our business may be adversely affected by third-party malicious or unintentional software applications that make changes to our users’ computers and interfere with our products and services. These software applications may change our users’ internet experience by hijacking queries to our websites, altering or replacing our search results, or otherwise interfering with our ability to connect with our users. The interference often occurs without disclosure to or consent from users, resulting in a negative experience, which users may associate with our websites. These software applications may be difficult to remove or disable, may reinstall themselves and may circumvent other applications’ efforts to block or remove them. In addition, our business may be adversely affected by the practices of third-party website owners, content providers and developers which interfere with our ability to crawl and index their web pages and contents including applications. The ability to provide a superior user experience is critical to our success. If we are unable to successfully combat malicious third-party software applications that interfere with our products and services, our reputation may be harmed. If a significant number of website owners, content providers and developers prevent us from indexing and including their high-quality web pages and contents including applications in our search results, the quality of our search results may be impaired.

We may not be able to prevent others from unauthorized use of our intellectual property, which could harm our business and competitive position.

We rely on a combination of copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods to protect our intellectual property rights. The protection of intellectual property rights in China may not be as effective as those in the United States or other countries. The steps we have taken may be inadequate to prevent the misappropriation of our technology. Reverse engineering, unauthorized

##### Table of Contents

copying or other misappropriation of our technologies could enable third parties to benefit from our technologies without paying us. Moreover, unauthorized use of our technology could enable our competitors to offer products and services that are comparable to or better than ours, which could harm our business and competitive position. We have in the past resorted to litigation to enforce our intellectual property rights, and may have to do so from time to time in the future. There is no guarantee that the competent courts will accept our claims and rule in our favor. Such litigation may result in substantial costs and diversion of resources and management attention.

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

Our future success depends heavily upon the continuing services of our management team, in particular our chairman and chief executive officer, Robin Yanhong Li. If one or more of our executives or other key personnel are unable or unwilling to continue in their present positions, we may not be able to replace them easily or at all, and our business may be disrupted and our financial condition and results of operations may be materially and adversely affected. Competition for management and key personnel is intense, the pool of qualified candidates is limited, and we may not be able to retain the services of our executives or key personnel, or attract and retain experienced executives or key personnel in the future.

If any of our executives or other key personnel joins a competitor or forms a competing company, we may lose customers, distributors, know-how and key personnel. Each of our executive officers and key employees has entered into an employment agreement with us, containing confidentiality and non-competition provisions. If any disputes arise between any of our executives or key personnel and us, we cannot assure you the extent to which any of these agreements may be enforced.

We rely on highly skilled personnel. If we are unable to retain or motivate them or hire additional qualified personnel, we may not be able to grow effectively.

Our performance and future success depend on the talents and efforts of highly skilled individuals. We will need to continue to identify, hire, develop, motivate and retain highly skilled personnel for all areas of our organization and business operations. Competition in the internet industry for qualified employees is intense. Our continued ability to compete effectively depends on our ability to attract new employees and to retain and motivate our existing employees. As competition in the internet industry intensifies, it may be more difficult for us to hire, motivate and retain highly skilled personnel. If we do not succeed in attracting additional highly skilled personnel or retaining or motivating our existing personnel, we may be unable to grow effectively.

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. In the past three years, we acquired certain businesses and intangible assets, through several strategic investments and acquisitions, such as our investment in Qunar Cayman Islands Limited, or Qunar, and Qiyi.com, Inc., and our acquisition of the online video business of PPStream Inc. and acquisition of 91 Wireless Websoft Limited, or 91 Wireless. We intend to make other strategic investments and acquisitions in the future if suitable opportunities arise. Investments and acquisitions involve uncertainties and risks, including:

| • |  | potential ongoing financial obligations and unforeseen or hidden liabilities, including liability for infringement of third-party copyrights or other intellectual property;

| • |  | failure to achieve the intended objectives, benefits or revenue-enhancing opportunities;

| • |  | costs and difficulties of integrating acquired businesses and managing a larger business;

| • |  | potentially significant goodwill impairment charges;

12

##### Table of Contents

| • |  | high acquisition and financing costs;

| • |  | possible loss of key employees of a target business;

| • |  | potential claims or litigation regarding our board’s exercise of its duty of care and other duties required under applicable law in connection with any of our significant acquisitions or investments approved by the board; and

| • |  | diversion of resources and management attention.

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.

We are subject to risks and uncertainties faced by companies in a rapidly evolving industry.

We operate in the rapidly evolving internet industry, which makes it difficult to predict our future results of operations. Accordingly, you should consider our future prospects in light of the risks and uncertainties experienced by companies in evolving industries. Some of these risks and uncertainties relate to our ability to:

| • |  | maintain our leading position in the Chinese language internet search market;

| • |  | offer new, innovative products and services and enhance our existing products and services with innovative and advanced technology to attract and retain a larger user base;

| • |  | attract users’ continuing use of internet search services;

| • |  | retain existing customers and attract additional customers and increase spending per customer;

| • |  | upgrade our technology to support increased traffic and expanded product and service offerings;

| • |  | further enhance our brand;

| • |  | respond to competitive market conditions;

| • |  | respond to evolving user preferences or industry changes;

| • |  | respond to changes in the regulatory environment and manage legal risks, including those associated with intellectual property rights;

| • |  | maintain effective control of our costs and expenses;

| • |  | execute our strategic investments and acquisitions and post-acquisition integrations effectively;

| • |  | attract, retain and motivate qualified personnel and maintain good relations with a young and growing work force; and

| • |  | build profitable operations in new markets and other overseas internet search markets we have entered into.

If we are unsuccessful in addressing any of these risks and uncertainties, our business may be materially and adversely affected.

Our historical growth rate may not be indicative of our future growth rate.

We have experienced substantial growth in recent years. Our total revenues and net income attributable to Baidu, Inc. grew at a compound annual growth rate of 63.7% and 63.1%, respectively, from 2009 to 2013. Our growth was driven in part by the growth in China’s internet and online marketing industries, which may not be indicative of future growth or be sustainable. Our past growth rate may not be indicative of our future growth rate.

Our indebtedness could adversely affect our financial condition and our ability to obtain additional capital on reasonable terms when necessary.

As of December 31, 2013, we had an aggregate of US$2.9 billion of outstanding indebtedness that will mature between 2014 and 2022 and we may incur additional indebtedness in the future. Our current and future debt requires us to dedicate a portion of our cash flow to service interest and principal payments and may limit our ability to engage in other transactions. Our ability to pay interest and repay the principal for our indebtedness is dependent upon our ability to manage our business operations, generate sufficient cash flows to service such debt and the other factors discussed in this section. There can be no assurance that we will be able to manage any of these risks successfully.

We may require additional capital to support our business growth or to respond to business opportunities, challenges or unforeseen circumstances. Our ability to obtain additional capital, if and when required, will depend on our business plans, investor demand, our operating performance, the condition of the capital markets, and other factors, and our indebtedness may limit our ability to borrow additional funds. We may have difficulty incurring new debt on terms that we would consider to be commercially reasonable, if at all. In addition, we may also need to refinance a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing may not be as favorable as the terms of our existing debt.

Our results of operations may fluctuate, which makes our results difficult to predict and could cause our results to fall short of expectations.

Our results of operations may fluctuate as a result of a number of factors, many of which are beyond our control. For these reasons, comparing our results of operations on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. Our quarterly and annual revenues and costs and expenses as a percentage of our revenues may be significantly different from our historical or projected figures. Our results of operations in future quarters may fall below expectations. Any of these events could cause the price of our ADSs to fall. Any of the risk factors listed in this “Risk Factors” section, and in particular the following factors, could cause our results of operations to fluctuate from quarter to quarter:

| • |  | general economic conditions in China and economic conditions specific to the internet, internet search and online marketing industries;

| • |  | our ability to continue to attract users to our websites despite the emergence of mobile applications;

| • |  | our ability to attract additional customers and increase spending per customer;

| • |  | the announcement or introduction of new or enhanced products and services by us or our competitors;

Because of the rapid growth of our business, our historical results of operations may not be useful to you in predicting our future results of operations. Our user traffic tends to be seasonal. For example, we generally experience less user traffic during public holidays and other special event periods in China. In addition, advertising and other marketing spending in China has historically been cyclical, reflecting overall economic conditions as well as budgeting and buying patterns. Our rapid growth has lessened the impact of the cyclicality and seasonality of our business. As we continue to grow, we expect that the cyclicality and seasonality in our business may cause our results of operations to fluctuate.

A severe and prolonged global economic recession and the slowdown in the Chinese economy may adversely affect our business, results of operations and financial condition.

The global financial markets experienced significant disruptions since 2008 and the United States, Europe and other economies went into recession. The recovery from the lows of 2008 and 2009 was uneven and is facing new challenges, including the escalation of the European sovereign debt crisis since 2011 and the slowdown of the Chinese economy in 2012. It is unclear whether the Chinese economy will resume its high growth rate. There is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies that have been adopted by the central banks and financial authorities of some of the world’s leading economies, including the United States and China. There have also been concerns over unrest in the Middle East and Africa, which have resulted in volatility in oil and other markets. There have also been concerns about the territorial disputes involving China in Asia and the economic effects. Economic conditions in China 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. Any prolonged slowdown in the global or Chinese economy may have a negative impact on our business, results of operations and financial condition, and continued turbulence in the international markets may adversely affect our ability to access the capital markets to meet liquidity needs. Our customers may reduce or delay spending with us, while we may have difficulty expanding our customer base fast enough, or at all, to offset the impact of decreased spending by our existing customers. In addition, to the extent we offer credit to any customer and the customer experiences financial difficulties due to the economic slowdown, we could have difficulty collecting payment from the customer.

Because we rely to a large extent on distributors in providing our P4P services, failure to retain key distributors or attract additional distributors could materially and adversely affect our business. Moreover, there is no assurance that our direct sales model in some key geographic markets will continue to be successful.

Online marketing is at a development stage in China and is not as widely accepted by or available to businesses in China as in the United States. As a result, we rely, to a large extent, on a nationwide distribution network of third-party distributors for our sales to, and collection of payment from, our P4P customers. If our distributors do not provide quality services to our P4P customers or otherwise breach their contracts with our P4P customers, we may lose customers and our results of operations may be materially and adversely affected. Since most of our distributors are not bound by long-term contracts, we cannot assure you that we will continue to maintain favorable relationships with them. If we fail to retain our key distributors or attract additional distributors on terms that are commercially reasonable, our business and results of operations could be materially and adversely affected.

We have transitioned to using our direct sales force to serve P4P customers in some key geographic markets, such as Beijing, Shanghai and major cities in Guangdong Province. There is no assurance that our direct sales model in those markets will continue to be successful. If we fail to maintain an adequate direct sales force, retain existing customers and continue to attract new customers in those markets, our business, results of operations and prospects could be materially and adversely affected.

We rely on our Baidu Union members for a significant portion of our revenues. If we fail to retain existing Baidu Union members or attract additional members, our revenue growth and profitability may be adversely affected.

We pay Baidu Union members a portion of our revenues based on click-throughs by users of Baidu Union members’ properties. We consider our Baidu Union critical to the future growth of our revenues. Some of our Baidu Union members, however, may compete with us in one or more areas of our business. Therefore, they may decide in the future to terminate their relationships with us. If our Baidu Union members decide to use a competitor’s or their own internet search services, our user traffic may decline, which may adversely affect our revenues. If we fail to attract additional Baidu Union members, our revenue growth may be adversely affected. In addition, if we have to share a larger portion of our revenues to retain existing Baidu Union members or attract additional members, our profitability may be adversely affected.

Our overseas operations may not be successful.

We have started to launch products and services in local languages to internet users in several countries. It is uncertain when the operation will become profitable, if at all. In particular, we rely on local telecommunication operators and service providers to provide us with network services and data center hosting services, and our systems for these international products and services are not redundant across different regions and data centers. Any interruption to the internet infrastructure or any data center may render our products and services in the region unavailable.

We face certain risks inherent in doing business internationally, including:

| • |  | difficulties in developing, staffing and simultaneously managing a foreign operation as a result of distance, language and cultural differences;

| • |  | longer customer payment cycles;

| • |  | currency exchange rate fluctuations;

| • |  | political or social unrest or economic instability;

| • |  | unexpected changes in laws or regulations;

| • |  | severe natural disasters; and

| • |  | potentially adverse tax consequences.

One or more of these factors could harm our overseas operations and consequently, could harm our overall results of operations.

If we are unable to adapt or expand our existing technology infrastructure to accommodate greater traffic or additional customer requirements, our business may be harmed.

Our Baidu.com website regularly serves a large number of users and customers and delivers a large number of daily page views. Our technology infrastructure is highly complex and may not provide satisfactory service in the future, especially as the number of users and customers increases. We may be required to upgrade our technology infrastructure to keep up with the increasing traffic on our Baidu.com website, such as increasing the

16

##### Table of Contents

capacity of our servers and the sophistication of our software. If we fail to adapt our technology infrastructure to accommodate greater traffic or customer requirements, our users and customers may become dissatisfied with our services and switch to our competitors’ websites, which could harm our business.

If we fail to detect fraudulent click-throughs, we could lose the confidence of our customers and our revenues could decline.

We are exposed to the risk of click-through fraud on our paid search results. Click-through fraud occurs when a person clicks paid search results for a reason other than to view the underlying content of search results. If we fail to detect fraudulent clicks or otherwise are unable to prevent this fraudulent activity, the affected customers may experience a reduced return on investments, or ROI, in our online marketing services and lose confidence in the integrity of our systems, and we may have to issue refunds to our customers. If this happens, we may be unable to retain existing customers or attract new customers for our online marketing services, and our online marketing revenues could decline. In addition, affected customers may also file legal actions against us claiming that we have over-charged or failed to refund them. Any such claims or similar claims, regardless of their merits, could be time-consuming and costly for us to defend against and could also adversely affect our brand and our customers’ confidence in the integrity of our systems.

More people are using devices other than personal computers to access the internet. If users do not widely adopt versions of our web search technology, products and services developed for these devices, our business could be adversely affected.

The number of people who access the internet through devices other than personal computers, including mobile phones, smartphones, handheld computers such as iPad and other tablets, and television set-top devices, is increasing dramatically. The varying display sizes, functionality, and memory associated with some alternative devices make the use of our products and services on such devices more difficult and the versions of our products and services developed for these devices may not be compelling to users, manufacturers, or distributors of devices. Each manufacturer or distributor may establish unique technical standards for its devices, and our products and services may not work or be accessible on these devices. Some manufacturers may also elect not to include our products on their devices. In addition, search queries are increasingly being undertaken through “apps” tailored to particular devices or social media platforms, which could affect our share of the search market over time. As new devices and new platforms are continually being released, it is difficult to predict the problems we may encounter in developing versions of our products and services for use on these alternative devices and we may need to devote significant resources to the creation, support, and maintenance of our products and services tailored for such devices. If we are unable to attract and retain a substantial number of alternative device manufacturers, distributors, and users to our products and services, or if we are slow to develop products and technologies that are more compatible with alternative devices, we may fail to capture a significant share of an increasingly important portion of the market for online services, which could adversely affect our business.

The successful operation of our business depends upon the performance and reliability of the internet infrastructure and fixed telecommunications networks in China.

Our business depends on the performance and reliability of the internet infrastructure in China. Almost all access to the internet is maintained through state-owned telecommunication operators under the administrative control and regulatory supervision of the Ministry of Industry and Information Technology, or the MIIT. In addition, the national networks in China are connected to the internet through international gateways controlled by the PRC government. These international gateways are the only channels through which a domestic user can connect to the internet. It is unpredictable whether a more sophisticated internet infrastructure will be developed in China. We may not have access to alternative networks in the event of disruptions, failures or other problems with China’s internet infrastructure. In addition, the internet infrastructure in China may not support the demands associated with continued growth in internet usage.

##### Table of Contents

We rely heavily on China Telecommunications Corporation, or China Telecom, China United Network Communications Group Company Limited, or China Unicom, and China Mobile Communications Corporation, or China Mobile, to provide us with network services and data center hosting services. We have entered into contracts with various local branches or subsidiaries of China Telecom, China Unicom and China Mobile to obtain data communications capacity. We have limited access to alternative services in the event of disruptions, failures or other problems with the fixed telecommunications networks of these companies, or if these companies otherwise fail to provide the services. In September 2013, the service of our Baidu Post Bar was inaccessible to many users for over four hours due to a failure of the internet infrastructure in Beijing. Any unscheduled service interruption could damage our reputation and result in a decrease in our revenues. Furthermore, we have no control over the costs of the services provided by these telecommunication companies. If the prices that we pay for telecommunications and internet services rise significantly, our gross margins could be adversely affected. In addition, if internet access fees or other charges to internet users increase, our user traffic may decrease, which in turn may harm our revenues.

Failure of information security could subject us to penalties, damage our reputation and brand, and harm our business and results of operations.

The internet industry is facing significant challenges regarding information security and privacy, including the storage, transmission and sharing of confidential information. We transmit and store over our systems confidential and private information of our users, customers, distributors and Baidu Union members, such as personal information, including names, user IDs and passwords, and payment or transaction related information. We are required by PRC law to ensure the confidentiality, integrity, availability and authenticity of the information of our users, customers, distributors and Baidu Union members, which is also essential to maintain their confidence in our online products and services.

We have adopted strict information security policies and deployed advanced measures to implement the policies, including, among others, advanced encryption technologies. However, advances in technology, increased level of sophistication and diversity of our products and services, increased level of expertise of hackers, new discoveries in the field of cryptography or others could still result in a compromise or breach of the measures that we use. Because of our leading market position in the internet industry in China, we believe we are a particularly attractive target for security breaches and hacking attacks. We have experienced in the past, and may experience in the future, such attacks. In August 2011, China’s Supreme People´s Court and Supreme People´s Procuratorate issued judicial interpretations regarding hacking and other internet crimes. In December 2012, the Standing Committee of the PRC National People’s Congress promulgated the Decision on Strengthening Network Information Protection, or the Network Information Protection Decision, to enhance the legal protection of information security and privacy on the internet. The Network Information Protection Decision also requires internet operators to take measures to ensure confidentiality of information of users. In July 2013, the MIIT promulgated the Provisions on Protection of Personal Information of Telecommunication and Internet Users to regulate the collection and use of users’ personal information in the provision of telecommunication service and internet information service in China. However, the effect of these new laws on curbing hacking and other illegal online activities still remains to be seen. Significant capital, managerial and human resources are required to comply with legal requirements, enhance information security and to address any issues caused by security failures. If we are unable to protect our systems, hence the information stored in our systems, from unauthorized access, use, disclosure, disruption, modification or destruction, such problems or security breaches could cause loss or give rise to our liabilities to the owners of confidential information, such as our users, customers, distributors and Baidu Union members, subject us to penalties imposed by administrative authorities, and disrupt our operations. Any negative publicity on our website’s safety or privacy protection mechanism and policy could also have a material and adverse effect on reputation and brand and harm our business and results of operations.

If we fail to maintain an effective system of internal control over financial reporting, we may lose investor confidence in the reliability of our financial statements.

We are subject to reporting obligations under the U.S. securities laws. The SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring every public company 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 our internal control over financial reporting. In addition, an independent registered public accounting firm must attest to and report on the effectiveness of our internal control over financial reporting. We have been subject to these requirements since the fiscal year ended December 31, 2006.

Our management has concluded that our internal control over financial reporting was effective as of December 31, 2013. See “Item 15. Controls and Procedures.” Our independent registered public accounting firm has issued an attestation report, which has concluded that our internal control over financial reporting was effective in all material aspects as of December 31, 2013. However, if we fail to maintain effective internal control over financial reporting in the future, our management and our independent registered public accounting firm may not be able to conclude that we have effective internal control over financial reporting at a reasonable assurance level. This could in turn result in loss of investor confidence in the reliability of our financial statements and negatively impact the trading price of our ADSs. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs, management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

We have limited business insurance coverage.

The insurance industry in China is still at a relatively early stage of development. Insurance companies in China offer limited business insurance products. We do not have any business liability or disruption insurance coverage for our operations in China. Any business disruption may result in our incurring substantial costs and the diversion of our resources.

We face risks related to health epidemics, severe weather conditions and other outbreaks.

Our business could be adversely affected by the effects of avian influenza, severe acute respiratory syndrome (SARS), the influenza A virus, severe weather conditions or other epidemic or outbreak. Health or other government regulations adopted in response to an epidemic, severe weather conditions such as snow storm, flood or hazardous air pollution, or other outbreaks may require temporary closure of our offices or internet cafes where many users access our websites. Such closures may disrupt our business operations and adversely affect our results of operations.

Risks Related to Our Corporate Structure

PRC laws and regulations governing our businesses and the validity of certain of our contractual arrangements are uncertain. If we are found to be in violation, we could be subject to sanctions. In addition, changes in PRC laws and regulations or changes in interpretations thereof may materially and adversely affect our business.

The PRC government restricts or imposes conditions on foreign investment in internet, online advertising, online audio and video services and mobile application distribution businesses. We and our PRC subsidiaries are considered foreign persons or foreign-invested enterprises under PRC foreign investment related laws. As a result, we and our PRC subsidiaries are subject to PRC legal restrictions on or conditions for foreign ownership of internet, online advertising, online audio and video services and mobile application distribution businesses. Due to these restrictions and conditions, we operate our websites and conduct online advertising, online audio and video services and mobile application distribution businesses in China through our consolidated affiliated entities. As all the nominee shareholders of our consolidated affiliated entities are either PRC citizens or PRC

19

##### Table of Contents

domestic enterprises, these entities are therefore considered as PRC domestic enterprises under PRC law. The “nominee shareholders” refer to those shareholders who have pledged their equity interest in our consolidated affiliated entities to us and entered into exclusive equity purchase and transfer option agreements with us as part of the contractual arrangements. Our contractual arrangements with our consolidated affiliated entities and the nominee shareholders allow us to have the power to direct the activities of these entities that most significantly impact their economic performance. These contractual arrangements demonstrate our ability and intention to continue to exercise the ability to absorb substantially all of the profits and the expected losses of the affiliated entities. In 2011, 2012 and 2013, we derived approximately 29%, 29% and 28% of our total revenues, respectively, from our consolidated affiliated entities through contractual arrangements.

There are substantial uncertainties regarding the interpretation and application of PRC laws and regulations, including, but not limited to, the laws and regulations governing our business, or the enforcement and performance of our contractual arrangements with our consolidated affiliated entities, including but not limited to Baidu Netcom and the nominee shareholders. These laws and regulations may be subject to change, and their official interpretation and enforcement may involve substantial uncertainty. New laws and regulations that affect existing and proposed future businesses may also be applied retroactively.

Although we believe we comply with current PRC laws and regulations, we cannot assure you that the PRC government would agree that our 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. The PRC government has broad discretion in determining penalties for violations of laws and regulations. If the PRC government determines that we do not comply with applicable law, it could revoke our business and operating licenses, require us to discontinue or restrict our operations, restrict our right to collect revenues, block our websites, require us to restructure our operations, impose additional conditions or requirements with which we may not be able to comply, impose restrictions on our business operations or on our customers, or take other regulatory or enforcement actions against us that could be harmful to our business. Any of these or similar occurrences could significantly disrupt our business operations or restrict us from conducting a substantial portion of our business operations, which could materially and adversely affect our business, financial condition and results of operations. If any of these occurrences results in our inability to direct the activities of any of our consolidated affiliated entities that most significantly impact its economic performance, and/or our failure to receive the economic benefits from any of our consolidated affiliated entities, we may not be able to consolidate the entity in our consolidated financial statements in accordance with U.S. GAAP.

If the PRC government were to classify P4P services as a form of online advertising or as part of internet content services, our effective tax rate may increase and we might be subject to sanctions and required to pay delinquent taxes.

PRC laws and regulations and administrative authorities currently do not classify P4P services as a form of online advertising or as part of internet content services that require an ICP license, or ICP services. However, we cannot assure you that the PRC government will not classify P4P services as a form of online advertising or as part of ICP services in the future. If new regulations characterize P4P services as a form of online advertising or as part of ICP services, our tax liability may increase, given the advertising revenues are subject to a 3% construction fee for culture undertakings in addition to the 6% value-added tax, or VAT, which has replaced the original 5% business tax for advertising revenues. See “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Taxation” for more information on PRC business tax and VAT. Moreover, if the change in classification of P4P services were to be retroactively applied, we might be subject to sanctions, including payment of delinquent taxes and fines. In addition, the classification of P4P services as a form of online advertising could subject us to an obligation to examine the content of our P4P customers’ listings on our websites and the associated risks. See “—Risks Related to Our Business—We have been and may again be subject to claims based on the content found on our websites or the results in our paid search listings.” Such examinations could be burdensome and increase our operating costs and expenses. Any change in the classification of P4P by the PRC government may materially and adversely affect our business, results of operations and financial condition.

Our contractual arrangements with our consolidated affiliated entities in China and the individual nominee shareholders may not be as effective in providing control over these entities as direct ownership.

Since PRC law restricts or imposes conditions on foreign equity ownership in internet, online advertising, online audio and video services and mobile application distribution companies in China, we operate our websites and conduct our online advertising, online audio and video services and mobile application distribution businesses through our consolidated affiliated entities in China. We have no equity interest in any of these entities and must rely on contractual arrangements to control and operate the businesses and assets held by our consolidated affiliated entities, including the domain names and trademarks that have been transferred from our subsidiaries to our consolidated affiliated entities in accordance with requirements of PRC law. These contractual arrangements may not be as effective in providing control over these entities as direct ownership. For example, our consolidated affiliated entities and the individual nominee shareholders could breach their contractual arrangements with us by, among other things, failing to operate our business, such as using the domain names and trademarks our subsidiaries have transferred to them or maintaining our websites, in an acceptable manner or taking other actions that are detrimental to our interests. If our consolidated affiliated entities or the individual nominee shareholders fail to perform their obligations under these contractual arrangements, we may have to incur substantial costs to enforce such arrangements, and rely on legal remedies under PRC law, including contract remedies, which may not be sufficient or effective. If we are unable to enforce these contractual arrangements, or if we suffer significant delay or other obstacles in the process of enforcing these contractual arrangements, we may not be able to have the power to direct the activities that most significantly affect the economic performance of our consolidated affiliated entities, and we may lose control over the assets owned by our consolidated affiliated entities, including our baidu.com domain name and website, and any other domain names and websites we have access to may not attract a large number of users and customers at the same level as baidu.com. As a result, our ability to conduct our business may be materially and adversely affected, and we may not be able to consolidate the financial results of the relevant affiliated entities into our consolidated financial statements in accordance with U.S. GAAP, which may materially and adversely affect our results of operations and damage our reputation.

Our contractual arrangements with our consolidated affiliated entities in China may result in adverse tax consequences to us.

As a result of our corporate structure and the contractual arrangements between our subsidiaries and each of our consolidated affiliated entities in China, we are subject to VAT at a rate of 6% as a result of the pilot VAT reform program on both revenues generated by our consolidated affiliated entities’ operations in China and revenues derived from our subsidiaries’ contractual arrangements with these consolidated affiliated entities. Where our consolidated affiliated entity is qualified as a VAT general taxpayer, the VAT charged by our subsidiaries on the revenues obtained from such consolidated affiliated entity based on the contractual arrangement between our subsidiaries and such consolidated affiliated entity will constitute input VAT for the consolidated affiliated entity, and will be creditable against output VAT arising in connection with VAT taxable activities carried out by the consolidated affiliated entity. See “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Taxation” for more information on the pilot VAT reform program. Moreover, we would be subject to adverse tax consequences if the PRC tax authorities were to determine that the contracts between our subsidiaries and these consolidated affiliated entities were not on an arm’s-length basis and therefore constituted a favorable transfer pricing. Under the PRC Enterprise Income Tax Law, or the EIT Law, an enterprise must submit its annual tax return together with information on related-party transactions to the PRC tax authorities. The PRC tax authorities may impose reasonable adjustments on taxation if they have identified any related party transactions that are inconsistent with arm’s-length principles. For example, the PRC tax authorities could request that our consolidated affiliated entities adjust their taxable income upward for PRC tax purposes. Such adjustment could adversely affect us by increasing our consolidated affiliated entities’ tax expenses without reducing our subsidiaries’ tax expenses, which could subject our consolidated affiliated entities to interest due on late payments and other penalties for under-payment of taxes.

We may have exposure to greater than anticipated tax liabilities.

We are subject to enterprise income tax, or EIT, business tax, VAT, and other taxes in many provinces and cities in China and our tax structure is subject to review by various local tax authorities. The determination of our provision for income tax and other tax liabilities requires significant judgment. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are reasonable, the ultimate decisions by the relevant tax authorities may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made.

The individual nominee shareholders of our consolidated affiliated entities may have potential conflicts of interest with us, which may adversely affect our business. We do not have any arrangements in place to address such potential conflicts.

We have designated individuals who are PRC nationals to be the nominee shareholders of our consolidated affiliated entities in China. For example, Robin Yanhong Li, our chairman, chief executive officer and co-founder, is also the principal nominee shareholder of Baidu Netcom, which is our principal consolidated affiliated entity.

Although the individual nominee shareholders are contractually obligated to act in good faith and in our best interest, they may still have potential conflicts of interest with us. For example, some individual nominee shareholders of our consolidated affiliated entities do not have a significant equity stake in our company other than the share options granted to them. We cannot assure you that when conflicts of interest arise, any or all of these individuals will act in the best interests of our company or such conflicts will be resolved in our favor. In addition, these individuals may breach, cause our consolidated affiliated entities to breach or refuse to renew, the existing contractual arrangements with us. Currently, we do not have any arrangements to address potential conflicts of interest between these individuals and our company, except that we could exercise our transfer option under the exclusive equity purchase and transfer option agreement with the relevant individual nomine shareholder to request him/her to transfer all of his/her equity ownership in the relevant consolidated affiliated entity to a PRC entity or individual designated by us. We rely on Mr. Robin Yanhong Li, who is also a director of our company, to abide by the Cayman Islands law, which provides that directors owe a fiduciary duty to the company, and those who are also directors or officers of our PRC subsidiaries to abide by PRC law, which provides that directors and officers owe a fiduciary duty to the company. Such fiduciary duty requires directors and/or officers to act in good faith and in the best interests of the company and not to use their positions for personal gains. There are, however, no specific provisions under the Cayman Islands or PRC law on how to address potential conflicts of interest. If we cannot resolve any conflict of interest or dispute between us and the individual nominee shareholders of our consolidated affiliated entities, we would have to rely on legal proceedings, which could disrupt our business, distract management and subject us to substantial uncertainty as to the outcome of any such legal proceedings.

We may be unable to collect long-term loans to the nominee shareholders of our consolidated affiliated entities in China.

As of the date of this annual report, we have made long-term loans in an aggregate principal amount of RMB935.1 million (US$154.5 million) to the nominee shareholders of our consolidated affiliated entities. We extended these loans to enable the nominee shareholders to fund the capitalization of these entities. As of the date of this annual report, all of the registered capital of our consolidated affiliated entities in China has been fully funded. We may in the future provide additional loans to the nominee shareholders of our consolidated affiliated entities in China in connection with any increase in their capitalization to the extent necessary and permissible under applicable law. Our ability to ultimately collect these loans will depend on the profitability of these consolidated affiliated entities and their operational needs, which are uncertain.

We are in the process of registering the pledges of equity interests by nominee shareholders of some of our consolidated affiliated entities, and we may not be able to enforce the equity pledges against any third parties who acquire the equity interests in good faith in the relevant consolidated affiliated entities before the pledges are registered.

The nominee shareholders of each of our consolidated affiliated entities have pledged all of their equity interests in the relevant consolidated affiliated entities to our subsidiaries. An equity pledge agreement becomes effective among the parties upon execution. However, according to the PRC Property Rights Law, an equity pledge is not perfected as a security property right unless it is registered with the relevant local administration for industry and commerce. The pledge relating to each of Baidu Netcom, Beijing Perusal Technology Co., Ltd., or Beijing Perusal, and BaiduPay has been registered with the relevant local administration for industry and commerce, while we are in the process of registering the pledge of the registered capital of certain of our newly acquired or established consolidated affiliated entities. Prior to the completion of the registration, we may not be able to successfully enforce the equity pledge against any third parties who have acquired property right interests in good faith in the equity interests in the relevant consolidated affiliated entities.

Risks Related to Doing Business in China

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

Most of our business operations are conducted in China. Accordingly, our business, results of operations, financial condition and prospects are affected by economic, political 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 Chinese government has implemented measures 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 government. In addition, the Chinese government continues to play a significant role in regulating industry development. The Chinese government also exercises significant control over China’s 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. Since 2012, growth of the Chinese economy has slowed. 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. For example, certain operating costs and expenses, such as employee compensation and office operating expenses, may increase as a result of higher inflation. Additionally, because a substantial portion of our assets consists of cash and cash equivalents and short-term investments, high inflation could significantly reduce the value and purchasing power of these assets.

Uncertainties with respect to the PRC legal system could adversely affect us.

We conduct our business primarily through our subsidiaries and consolidated affiliated entities in China. Our operations in China are governed by PRC laws and regulations. Our subsidiaries are generally subject to laws and regulations applicable to foreign investments in China. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value.

##### Table of Contents

PRC laws and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China for the past decades. 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. The following are a few examples:

| • |  | China enacted the Anti-Monopoly Law, which became effective on August 1, 2008. Because the Anti-Monopoly Law and the related regulations are still new, and there have been very few court rulings and judicial or administrative interpretations on certain key concepts used in the law, it is uncertain how the implementation and enforcement of the Anti-Monopoly Law and the related regulations would affect our business.

| • |  | The PRC Tort Liability Law became effective on July 1, 2010. In accordance with the Tort Liability Law, where an internet service provider is informed or knows that an internet user is infringing upon other persons’ rights and interests through its internet service but fails to take necessary actions, it will be jointly and severally liable with the internet user as to the damages suffered by the right holders as a result of the infringing activity known to the internet service provider. The interpretation of the applicability and enforceability of the Tort Liability Law on internet search providers remain uncertain, thus we are not sure how it would affect our business.

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. As a result, we may not be aware of our potential violation of these policies and rules. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention.

We may be adversely affected by the complexity, uncertainties and changes in PRC regulation of internet business and companies.

The PRC government regulates the internet industry extensively, 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 uncertainty. As a result, under 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 PRC government regulation of the internet industry include, but are not limited to, the following:

| • |  | We only have contractual control over our websites. We do not own the websites due to the restriction of foreign investment in businesses providing value-added telecommunication services in China, including online information services.

| • |  | The licensing requirements relating to the internet business in China are uncertain and evolving. This means that permits, licenses or operations at some of our PRC subsidiaries and consolidated affiliated entities may be subject to challenge, or we may not be able to obtain or renew certain permits or licenses, including without limitation, a Value-Added Telecommunication Business Operating License, which is issued by the MIIT, an Internet News License, which is issued by the State Council News Office, an Internet Culture Business Permit with the permitted scope of business covering online game operation and online game virtual currency issuance or trading, which is issued by the Ministry of Culture, an Online Audio/Video Program Transmission License, which is issued by the State Administration of Radio Film and Television, or SARFT (which was consolidated with the General Administration of Press and Publication, or GAPP, and is currently known as the State Administration of Press Publication, Radio, Film and Television, or SAPPRFT), an Internet Publication License, which is issued by the GAPP (which was consolidated with the SARFT and is currently known as SAPPRFT), a Surveying and Mapping Qualification Certificate for internet map services, which is issued by the State Bureau of Surveying and Mapping, a Payment Service Permit, which is issued by the People’s

##### Table of Contents

| Bank of China, and a Qualification Certificate for Internet Drug Information Services, which is issued by provincial branch of the State Food and Drug Administration. Failure to obtain or renew these permits and licenses may significantly disrupt our business, or subject us to sanctions, requirements to increase capital or other conditions or enforcement, or compromise enforceability of related contractual arrangements, or have other harmful effects on us.

| • |  | New laws and regulations may be promulgated to regulate internet activities, including online advertising and online payment. Other aspects of our online operations may be regulated in the future. If these new laws and regulations are promulgated, additional licenses may be required for our online 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.

We provide value-added telecommunications services through our consolidated affiliated entities, which hold the required licenses. In July 2006, the MIIT 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 services 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 Business Operating License or its shareholders must directly own the domain names and trademarks used by the license holder in its 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 these facilities in the regions covered by its license. Baidu Netcom, Beijing Perusal and BaiduPay, our consolidated affiliated entities, own the necessary domain names and trademarks, including pending trademark applications and have the necessary personnel and facilities to operate our websites.

We offer online games provided by our game operator partners on our websites owned and operated by our consolidated affiliated entities. We have also acquired 91 Wireless, which operates two leading smartphone application distribution platforms in China as well as a mobile game platform through consolidated affiliated entities. In September 2009, the GAPP (currently known as SAPPRFT) together with several other government agencies issued a notice, or the Circular 13, prohibiting foreign investors from participating in online game operating businesses through wholly-owned enterprises, equity joint ventures or cooperative joint ventures in China. Circular 13 expressly prohibits foreign investors from gaining control over or participating in PRC operating companies’ online game operations through indirect means, such as establishing joint venture companies, entering into contractual arrangements with or providing technical support to the operating companies, or through a disguised form, such as incorporating user registration, user account management or payment through game cards into online game platforms that are ultimately controlled or owned by foreign investors. Other government agencies that also have the authority to regulate online game operations in China, such as the Ministry of Culture and the MIIT, did not join the GAPP in issuing the Circular 13. To date, neither the GAPP nor SAPPRFT has issued any interpretation of the Circular 13. Due to the ambiguity among various regulations on online games and a lack of interpretations from the relevant PRC authorities governing online game operations, there are uncertainties regarding whether PRC authorities would consider our relevant contractual arrangements to be foreign investment in online game operation businesses. While we are not aware of any online game companies which use the same or similar contractual arrangements as ours having been penalized or ordered to terminate operation by PRC authorities claiming that the contractual arrangements constitute control over, or participation in, the operation of online game operations through indirect means, it is unclear whether and how the various regulations of the PRC authorities might be interpreted or implemented in the future. If our relevant contractual arrangements were deemed to be “indirect means” or “disguised form” under the Circular 13, the relevant contractual arrangements may be challenged by the SAPPRFT or other governmental authorities. If we were found to be in violation of the Circular 13 to operate our mobile game platform, the SAPPRFT, in conjunction with relevant regulatory authorities, would have the power to investigate

25

##### Table of Contents

and deal with such violations, including in the most serious cases, suspending or revoking the relevant licenses and registrations. If we were found to be in violation of any existing or future PRC laws or regulations, including the MIIT notice and the Circular 13, the relevant regulatory authorities would have broad discretion in dealing with such violations.

As we enter into new businesses, we may encounter additional regulatory uncertainties. For example, it remains unclear whether the provision of online payment services by BaiduPay will require BaiduPay to apply for a value-added telecommunications business operating license for “online data processing and transaction processing businesses” as provided in the Catalog of Telecommunications Businesses promulgated by the MIIT. In addition, in March 2014, according to reports on certain websites, the People’s Bank of China has formulated a draft of the Administrative Measures on the Online Payment Business of Payment Institutions for the purpose of soliciting opinions from selected groups on certain proposed changes to laws relating to online payments, such as the imposition of limits on the amounts that can be paid for consumption purposes from online payment accounts opened with online payment institutions. There are substantial uncertainties as to if and when the draft administrative measures will be adopted into law and what further changes will be made to such measures prior to or during such adoption. If the draft administrative measures are adopted into law in the future, our Baidu Wallet business may be adversely affected.

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.

Regulation and censorship of information disseminated over the internet in China may adversely affect our business, and subject us to liability for information displayed on or linked to our websites and negative publicity in international media.

The PRC government has adopted regulations governing internet access and distribution of news and other information over the internet. Under these regulations, internet content providers and internet publishers are prohibited from posting or displaying over the internet content that, among other things, violates PRC laws and regulations, impairs the national dignity of China, or is reactionary, obscene, superstitious, fraudulent or defamatory. Failure to comply with these requirements may result in the revocation of licenses to provide internet content and other licenses and the closure of the concerned websites. In the past, failure to comply with these requirements has resulted in the closure of certain websites. The website operator may also be held liable for the censored information displayed on or linked to the website.

In particular, the MIIT has published regulations that subject website operators to potential liability for content displayed on their websites and the actions of users and others using their systems, including liability for violations of PRC laws and regulations prohibiting the dissemination of content deemed to be socially destabilizing. The Ministry of Public Security has the authority to order any local internet service provider to block any internet website at its sole discretion. From time to time, the Ministry of Public Security has stopped the dissemination over the internet of information which it believes to be socially destabilizing. The State Secrecy Bureau is also authorized to block any website it deems to be leaking state secrets or failing to meet the relevant regulations relating to the protection of state secrets in the dissemination of online information. Furthermore, we are required to report any suspicious content to relevant governmental authorities, and to undergo computer security inspections. If we fail to implement the relevant safeguards against security breaches, our websites may be shut down and our business and ICP licenses may be revoked. In addition, internet companies that provide bulletin board systems (BBS), chat rooms or similar services must apply for approval from relevant authorities in practice.

Although we attempt to monitor the content in our search results and on our online communities such as Baidu Post Bar, we are not able to control or restrict the content of other internet content providers linked to or

26

##### Table of Contents

accessible through our websites, or content generated or placed on our Baidu Post Bar message boards or our other online communities by our users. To the extent that PRC regulatory authorities find any content displayed on our websites objectionable, they may require us to limit or eliminate the dissemination of such information on our websites. If third-party websites linked to or accessible through our websites conduct unlawful activities such as online gambling on their websites, PRC regulatory authorities may require us to report such unlawful activities to relevant authorities and to remove the links to such websites, or they may suspend or shut down the operation of these third-party websites. PRC regulatory authorities may also temporarily block access to certain websites for a period of time for reasons beyond our control. Any of these actions may reduce our user traffic and adversely affect our business. In addition, we may be subject to penalties for violations of those regulations arising from information displayed on or linked to our websites, including a suspension or shutdown of our online operations.

Moreover, our compliance with PRC regulations governing internet access and distribution of news and other information over the internet may subject us to negative publicity or even legal actions outside of China. In May 2011, eight New York residents filed a lawsuit against us before the U.S. District Court for the Southern District of New York accusing us of aiding Chinese censorship in violation of the U.S. Constitution. In March 2014, the U.S. District Court for the Southern District of New York granted our motion for judgment on the pleadings based upon the First Amendment to the U.S. Constitution and dismissed the plaintiffs’ complaint in its entirety. Even though we have won the case, we cannot assure you that the plaintiffs’ will not appeal this decision and our reputation may be adversely affected among users and investors outside of China.

A notice issued by the PRC Ministry of Culture in August 2009 may affect our online music services.

In August 2009, the PRC Ministry of Culture promulgated the Notice on Strengthening and Improving the Content Review of Online Music, which provides, among others that only “internet culture operating entities” approved by the Ministry of Culture may engage in the production, release, dissemination (including providing direct links to music products) and importation of online music products. In addition, it is required that imported music products must pass prior content review by the Ministry of Culture before they are put on internet and domestic music products must be filed with the Ministry of Culture within 30 days after the commencement date of the online operation of the domestic music products. We hold an Internet Culture Business Permit granted by the Ministry of Culture, which allows us to engage in “internet culture activities” as defined in the relevant regulations promulgated by the Ministry of Culture. See “Item 4.B. Information on the Company—Business Overview—Regulation—Regulations on Internet Culture Activities.” We provide music for users to stream and download on our platform and we have obtained licenses from many content providers. We have been communicating with the government authority in order to comply with the review or filing requirement. If we are found by the Ministry of Culture to have failed to fully comply with the requirements of this notice, we could be subject to administrative penalties, including an order to stop providing the music products that have not been reviewed by or filed with the Ministry of Culture, fines, or confiscation of income derived from activities deemed in violation of the notice. Any of these occurrences could adversely affect our business and results of operations.

The discontinuation of any of the preferential income tax treatments currently available to us in the PRC could have a material and adverse effect on our result of operations and financial condition.

Pursuant to the EIT Law, as further clarified by subsequent tax regulations implementing the EIT Law, foreign-invested enterprises and domestic enterprises are subject to EIT at a uniform rate of 25%. Certain enterprises may still benefit from a preferential tax rate of 15% under the EIT Law if they qualify as “High and New Technology Enterprises strongly supported by the state,” subject to certain general factors described in the EIT Law and the related regulations.

Some of our principal PRC subsidiaries and consolidated affiliated entities, including Baidu Online Network Technology (Beijing) Co., Ltd., or Baidu Online, Baidu.com Times Technology (Beijing) Co., Ltd., or Baidu Times, Baidu Netcom and Baidu (China) Co., Ltd., or Baidu China, and certain other PRC subsidiaries and consolidated affiliated entities, are entitled to enjoy a preferential tax rate of 15% due to their qualification as “High and New Technology Enterprise”, which has a term of three years. If any or some of these PRC subsidiaries and consolidated affiliated entities fail to maintain the “High and New Technology Enterprise” qualification, their applicable EIT rate will be up to 25%. Furthermore, in April 2013, Baidu Online obtained the

27

##### Table of Contents

certificate of “Key Software Enterprise” jointly issued by the National Development and Reform Commission, MIIT, Ministry of Commerce and State Administration of Taxation, which entitled it to enjoy a preferential income tax rate of 10% for 2011 and 2012. In December 2013, Baidu Online has obtained the certificate of “Key Software Enterprise” status for 2013 and 2014 from the relevant government authorities. There is no assurance that Baidu Online will continue to maintain the “Key Software Enterprise” status. See “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Taxation—PRC Enterprise Income Tax.”

The discontinuation of any of the above-mentioned preferential income tax treatments currently available to us in the PRC could have a material and adverse effect on our result of operations and financial condition. We cannot assure you that we will be able to maintain our current effective tax rate in the future.

If our PRC subsidiaries declare and distribute dividends to their respective offshore parent companies, we will be required to pay more taxes, which could have a material and adverse effect on our result of operations.

Under the EIT Law and related regulations, dividends, interests, rent or royalties payable by a foreign-invested enterprise, such as our PRC subsidiaries, to any of its foreign non-resident enterprise investors, and proceeds from any such foreign enterprise investor’s disposition of assets (after deducting the net value of such assets) are subject to a 10% withholding tax, unless the foreign enterprise investor’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced rate of withholding tax. Undistributed profits earned by foreign-invested enterprises prior to January 1, 2008 are exempted from any withholding tax. The British Virgin Islands, where Baidu Holdings Limited, the direct parent company of our PRC subsidiary Baidu Online, is incorporated, does not have such a tax treaty with China. Hong Kong has a tax arrangement with China that provides for a 5% withholding tax on dividends subject to certain conditions and requirements, such as the requirement that the Hong Kong resident enterprise own at least 25% of the PRC enterprise distributing the dividend at all times within the 12-month period immediately preceding the distribution of dividends and be a “beneficial owner” of the dividends. For example, Baidu (Hong Kong) Limited, which directly owns our PRC subsidiaries Baidu China and Baidu Times, is incorporated in Hong Kong. However, if Baidu (Hong Kong) Limited is not considered to be the beneficial owner of dividends paid to it by Baidu China and Baidu Times under the tax circulars promulgated in February and October 2009, such dividends would be subject to withholding tax at a rate of 10%. See “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Taxation—PRC Enterprise Income Tax.” If our PRC subsidiaries declare and distribute profits earned after January 1, 2008 to us in the future, such payments will be subject to withholding tax, which will increase our tax liability and reduce the amount of cash available to our company.

We may be deemed a PRC resident enterprise under the EIT Law, which could subject us to PRC taxation on our global income, and which may have a material and adverse effect on our results of operations.

Under the EIT Law and related regulations, an enterprise established outside of the PRC with “de facto management body” within the PRC is considered a PRC resident enterprise and is subject to the EIT at the rate of 25% on its worldwide income as well as PRC EIT reporting obligations. The related regulations define the term “de facto management body” as “the establishment that exercises substantial and overall management and control over the production, business, personnel, accounts and properties of an enterprise.” The State Administration of Taxation issued a SAT Circular 82 in April 2009, which provides certain specific criteria for determining whether the “de facto management body” of a Chinese-controlled overseas-incorporated enterprise is located in China. In July 2011, the State Administration of Taxation issued additional rules to provide more guidance on the implementation of SAT Circular 82. See “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Taxation—PRC Enterprise Income Tax.” Although the SAT Circular 82 and the additional guidance apply only to overseas registered enterprises controlled by PRC enterprises, not to those controlled by PRC individuals or foreigners, the criteria set forth in SAT Circular 82 may reflect the State Administration of Taxation’s general position on how the “de facto management body” test should be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises or individuals. If we are deemed a PRC resident enterprise, we may be subject to the EIT at 25% on our global income, except that the dividends we receive from our PRC subsidiaries may be exempt from the EIT to the extent such dividends are deemed as “dividends among qualified PRC resident enterprises.” If we are deemed a

28

##### Table of Contents

PRC resident enterprise and earn income other than dividends from our PRC subsidiaries, a 25% EIT on our global income could significantly increase our tax burden and materially and adversely affect our cash flow and profitability.

Under PRC tax laws, dividends payable by us and gains on the disposition of our shares or ADSs may be subject to PRC taxation.

If we are considered a PRC resident enterprise under the EIT Law, our shareholders and ADS holders who are deemed non-resident enterprises may be subject to the EIT at the rate of 10% upon the dividends payable by us or upon any gains realized from the transfer of our shares or ADSs, if such income is deemed derived from China, provided that (i) such foreign enterprise investor has no establishment or premises in China, or (ii) it has establishment or premises in China but its income derived from China has no real connection with such establishment or premises. If we are required under the EIT Law to withhold PRC income tax on our dividends payable to our non-PRC resident enterprise shareholders and ADS holders, or if any gains realized from the transfer of our shares or ADSs by our non-PRC resident enterprise shareholders and ADS holders are subject to the EIT, your investment in our shares or ADSs could be materially and adversely affected.

Furthermore, if we are considered a PRC resident enterprise and relevant PRC tax authorities consider dividends we pay with respect to our shares or ADSs and the gains realized from the transfer of our shares or ADSs to be income derived from sources within the PRC, it is possible that such dividends and gains earned by non-resident individuals may be subject to PRC individual income tax at a rate of 20%. If we are required under PRC tax laws to withhold PRC income tax on dividends payable to our non-PRC investors that are non-resident individuals or if you are required to pay PRC income tax on the transfer of our shares or ADSs, the value of your investment in our shares or ADSs may be materially and adversely affected.

Our subsidiaries and consolidated affiliated entities in China are subject to restrictions on paying dividends and making other payments to our holding company.

Baidu, Inc. is our holding company incorporated in the Cayman Islands and does not conduct any business operations other than holding equity interests in our subsidiaries. As a result of the holding company structure, it currently relies on dividend payments from our subsidiaries in China. However, PRC regulations currently permit payment of dividends only out of accumulated profits, as determined in accordance with PRC accounting standards and regulations. Our subsidiaries and consolidated affiliated entities in China are also required to set aside a portion of their after-tax profits according to PRC accounting standards and regulations to fund certain reserve funds. The PRC government also imposes controls on the conversion of RMB into foreign currencies and the remittance of foreign currencies out of China. We may experience difficulties in completing the administrative procedures necessary to obtain and remit foreign currency. See “—Governmental control of currency conversion may affect the value of your investment.” Furthermore, if our subsidiaries or consolidated affiliated entities in China incur debt on their own in the future, the instruments governing the debt may restrict their ability to pay dividends or make other payments. If our subsidiaries and consolidated affiliated entities in China are unable to pay dividends or make other payments to us, we may be unable to pay dividends on our ordinary shares and ADSs.

Governmental control of currency conversion may affect the value of your investment.

The PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of foreign currency out of China. We receive most of our revenues in RMB. Under our current structure, our income at the Cayman Islands holding company level will primarily be derived from dividend payments from our PRC subsidiaries. Shortages in the availability of foreign currency may restrict the ability of our PRC subsidiaries and consolidated affiliated entities to remit sufficient foreign currency to pay dividends or other payments to us, or otherwise satisfy their foreign currency denominated obligations. Under existing PRC foreign exchange regulations, payments of current account items, including profit distributions, interest payments and expenditures from trade-related transactions, can be made in foreign currencies without prior approval from the PRC State Administration of Foreign Exchange, or SAFE, by complying with certain procedural requirements. However, approval from appropriate government authorities is required where RMB is to be converted into foreign currency and remitted out of China to pay capital expenses such as the repayment of

29

##### Table of Contents

loans denominated in foreign currencies. The PRC government may also at its discretion restrict access in the future to foreign currencies for current account transactions. If the foreign exchange control system prevents us from obtaining sufficient foreign currency to satisfy our currency demands, we may not be able to pay dividends in foreign currencies to our shareholders or ADS holders.

PRC regulation of loans to and direct investment in PRC entities by offshore holding companies and governmental control of currency conversion may delay or prevent us from making loans or additional capital contributions to our PRC subsidiaries, which could adversely affect our ability to fund and expand our business.

Baidu, Inc. is our offshore holding company conducting operations in China through our PRC subsidiaries and consolidated affiliated entities. We may make loans to our PRC subsidiaries and consolidated affiliated entities, or we may make additional capital contributions to our PRC subsidiaries. Loans by Baidu, Inc. or any of our offshore subsidiaries to our PRC subsidiaries, which are treated as foreign-invested enterprises under PRC law, are subject to PRC regulations and foreign exchange loan registrations. Such loans to any of our PRC subsidiaries to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of SAFE. The statutory limit for the total amount of foreign debts of a foreign-invested enterprise is the difference between the amount of total investment as approved by the PRC Ministry of Commerce or its local counterpart and the amount of registered capital of such foreign-invested enterprise. Any medium or long-term loans by Baidu, Inc. or any of our offshore subsidiaries to our consolidated affiliated entities, which are domestic PRC entities, must be approved by the National Development and Reform Commission and SAFE, or their relevant local counterparts. We may also decide to finance our PRC subsidiaries by means of capital contributions. These capital contributions must be approved by the PRC Ministry of Commerce or its local counterpart. Meanwhile, we are not likely to finance the activities of our consolidated affiliated entities by means of capital contributions given the PRC legal restrictions on foreign ownership of internet, online advertising, online audio and video services and mobile application distribution businesses.

In August 2008, SAFE promulgated a SAFE Circular No. 142 regulating the conversion by a foreign-invested enterprise of foreign currency registered capital into RMB by restricting how the converted RMB may be used. SAFE Circular No. 142 provides that the RMB capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used for purposes within the business scope approved by the applicable government authority and may not be used for equity investments within the PRC. In addition, SAFE strengthened its oversight of the flow and use of the RMB capital converted from foreign currency registered capital of a foreign-invested enterprise. The use of such RMB capital may not be altered without SAFE’s approval, and such RMB capital may not in any case be used to repay RMB loans if the proceeds of such loans have not been used. Furthermore, SAFE promulgated a SAFE Circular No. 59 in November 2010, which requires that the government authorities closely examine the authenticity of settlement of net proceeds from offshore offerings and the net proceeds be settled in the manner described in the offering documents. SAFE also promulgated a SAFE Circular No. 45 in November 2011, which, among other things, restrict a foreign-invested enterprise from using RMB converted from its registered capital to provide entrusted loans or repay loans between non-financial enterprises. Violations of these circulars could result in severe monetary or other penalties.

In light of the various requirements imposed by PRC regulations on loans to and direct investment in PRC entities by offshore holding companies, including SAFE Circulars referred to above, 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 or capital contributions by us to our PRC subsidiaries and conversion of such loans or capital contributions into RMB. If we fail to complete such registrations or obtain such approvals, our ability to capitalize or otherwise fund our PRC operations may be negatively affected, which could adversely affect our ability to fund and expand our business.

##### Table of Contents

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may limit our ability to inject capital into our PRC subsidiaries, limit our subsidiaries’ ability to increase their registered capital or distribute profits to us, or may otherwise adversely affect us.

SAFE Circular No. 75 effective from November 2005 and a series of implementation rules and guidance issued by SAFE, including the most recent circular relating to operating procedures that came into effect in July 2011, require PRC residents and PRC corporate entities to register with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special purpose vehicle, or SPV, for the purposes of overseas equity financing activities. These regulations apply to our shareholders who are PRC residents and may apply to any offshore acquisitions that we make in the future.

Under these SAFE regulations, PRC residents who make, or have previously made, direct or indirect investments in an SPV are required to register those investments. In addition, any PRC resident who is a direct or indirect shareholder of an SPV is required to update the previously filed registration with the local branch of SAFE, with respect to that SPV, to reflect any material change involving its round-trip investment, capital variation, such as an increase or decrease in capital, transfer or swap of shares, merger, division, long-term equity or debt investment or creation of any security interest. Moreover, the PRC subsidiaries of that SPV are required to urge the PRC resident shareholders to update their SAFE registration with the local branch of SAFE when such updates are required under applicable SAFE regulations. If any PRC shareholder fails to make the required SAFE registration or update the previously filed registration, the PRC subsidiaries of that SPV may be prohibited from distributing their profits and the proceeds from any reduction in capital, share transfer or liquidation, to their SPV parent, and the SPV may also be prohibited from injecting additional capital into their PRC subsidiaries. Moreover, failure to comply with the various SAFE registration requirements described above could result in liability under PRC law for evasion of applicable foreign exchange restrictions.

We have notified holders of ordinary shares of our company whom we know are PRC residents to register with the local SAFE branch and update their registrations as required under the SAFE regulations described above. We are aware that Mr. Robin Yanhong Li, our chairman, chief executive officer and principal shareholder, who is a PRC resident, has registered with the relevant local SAFE branch, and is in the process of updating such registration to reflect recent changes as a result of certain acquisitions. We, however, cannot provide any assurances that all of our shareholders who are PRC residents will file all applicable registrations or update previously filed registrations as required by these SAFE regulations. The failure or inability of our PRC resident shareholders to comply with the registration procedures may subject the PRC resident shareholders to fines and legal sanctions, restrict our cross-border investment activities, or limit our PRC subsidiaries’ ability to distribute dividends to or obtain foreign exchange-dominated loans from our company.

As it is uncertain how the SAFE regulations described above will be interpreted or implemented, we cannot predict how these regulations will affect our business operations or future strategy. For example, we may be subject to 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 results of operations and financial condition. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or the owners of such company will be able to obtain the necessary approvals or complete the necessary filings and registrations required by the SAFE 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 stock 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 on Issues concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly-Listed Company, or the Stock Option Rule, replacing the earlier rules promulgated in March 2007. Under the Stock Option Rule, PRC residents who are granted stock options by an overseas publicly listed company are required,

31

##### Table of Contents

through a PRC agent or PRC subsidiary of such overseas publicly listed company, to register with SAFE and complete certain other procedures. We and our PRC resident employees who have been granted stock options are subject to these regulations. We have designated our PRC subsidiary Baidu Online to handle the registration and other procedures required by the Stock Option Rule. If we or our PRC optionees fail to comply with these regulations in the future, we or our PRC optionees and their local employers may be subject to fines and legal sanctions.

PRC regulations establish complex procedures for some acquisitions conducted by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China.

The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, adopted by six PRC regulatory agencies in August 2006, among other things, established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time-consuming and complex. In addition, the Implementing Rules Concerning Security Review on the Mergers and Acquisitions by Foreign Investors of Domestic Enterprises, issued by the PRC Ministry of Commerce in August 2011, specify that mergers and acquisitions by foreign investors involved in “an industry related to national security” are subject to strict review by the PRC Ministry of Commerce, and prohibit any activities attempting to bypass such security review, including by structuring the transaction through a proxy or contractual control arrangement. We believe that our business is not in an industry related to national security, but we cannot preclude the possibility that the PRC Ministry of Commerce or other government agencies may publish explanations contrary to our understanding or broaden the scope of such security reviews in the future, in which case our future acquisitions in the PRC, including those by way of entering into contractual control arrangements with target entities, may be closely scrutinized or prohibited. Moreover, the Anti-Monopoly Law requires that the PRC Ministry of Commerce be notified in advance of any concentration of undertaking if certain filing thresholds are triggered. We may grow our business in part by directly acquiring complementary businesses in China. Complying with the requirements of the laws and regulations mentioned above and other PRC regulations to complete such transactions could be time-consuming, and any required approval processes, including obtaining approval from the Ministry of Commerce, may delay or inhibit our ability to complete such transactions, which could affect our ability to expand our business or maintain our market share. Our ability to expand our business or maintain or expand our market share through future acquisitions would as such be materially and adversely affected.

Our auditor, like other independent registered public accounting firms operating in China, is not permitted to be subject to inspection by Public Company Accounting Oversight Board, and as such, investors may be deprived of the benefits of such inspection.

Our independent registered public accounting firm that issues the audit reports included in our annual reports filed with the SEC, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), or PCAOB, is required by the laws of the United States to undergo regular inspections by PCAOB to assess its compliance with the laws of the United States and professional standards. Because our auditor is located in China, a jurisdiction where PCAOB is currently unable to conduct inspections without the approval of the PRC authorities, our auditor, like other independent registered public accounting firms operating in China, is currently not inspected by 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.

Inspections of other firms that PCAOB has conducted outside of China have identified deficiencies in those firms’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. The inability of PCAOB to conduct inspections of independent registered public

32

##### Table of Contents

accounting firms operating in China makes it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections.

We may be adversely affected by the outcome of the administrative proceedings brought by the SEC against the Big 4 PRC-based accounting firms.

In December 2012, the SEC brought administrative proceedings against the Big 4 accounting firms in China, including our independent registered public accounting firm, alleging that these accounting firms had violated U.S. securities laws and the SEC’s rules and regulations thereunder by failing to provide to the SEC the firms’ audit papers and other documents related to certain PRC-based companies that are publicly traded in the United States. On January 22, 2014, the Administrative Law Judge presiding over the matter reached an initial decision that the firms had each violated the SEC’s rules of practice by failing to produce the audit work papers and related documents directly to the SEC. The initial decision further determined that each of the firms should be censured and barred from practicing before the SEC for a period of six months. The Big 4 PRC-based accounting firms recently appealed the initial administrative law decision to the SEC. The initial administrative law decision will not become effective until and unless it is endorsed by the full SEC. The accounting firms can then further appeal the final decision of the SEC through the federal appellate courts. We were not and are not subject to any SEC investigations, nor are we involved in the proceedings brought by the SEC against the accounting firms. However, the independent registered public accounting firm that issues the audit reports included in our annual reports filed with the SEC is one of the four accounting firms subject to the six month suspension from practicing before the SEC in the initial administrative law decision. We may therefore be adversely affected by the outcome of the proceedings, along with other U.S.-listed companies audited by these accounting firms.

While we cannot predict the outcome of the SEC’s review, nor that of any subsequent appeal process, if the Big 4 PRC-based accounting firms, including our independent registered public accounting firm, are ultimately temporarily barred 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 to not be in compliance with the requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Such a determination could ultimately lead to our delisting from NASDAQ or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

Fluctuation in the value of the RMB may have a material and adverse effect on your investment.

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China’s political and economic conditions and foreign exchange policies. The conversion of RMB into foreign currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. The PRC government allowed the RMB to appreciate by more than 20% against the U.S. dollar between July 2005 and July 2008. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RMB and the U.S. dollar remained within a narrow band. Since June 2010, the PRC government has allowed the RMB to appreciate slowly against the U.S. dollar again, though there have been periods when the U.S. dollar has appreciated against the Renminbi as well. 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.

Our revenues and costs are mostly denominated in RMB. Any significant revaluation of RMB may materially and adversely affect our cash flows, revenues, earnings and financial position, and the value of, and any dividends payable on, our ADSs in U.S. dollars. For example, an appreciation of RMB against the U.S. dollar would make any new RMB denominated investments or expenditures more costly to us, to the extent that we need to convert U.S. dollars into RMB for such purposes. An appreciation of RMB against the U.S. dollar would also result in foreign currency translation losses for financial reporting purposes when we

##### Table of Contents

translate our U.S. dollar denominated financial assets into RMB, as RMB is our reporting currency. Conversely, a significant depreciation of the RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of our earnings, which in turn could adversely affect the price of our ADSs.

We face uncertainties with respect to indirect transfers of equity interests in PRC resident enterprises by their non-PRC holding companies.

Pursuant to the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises, or Circular 698, issued by the State Administration of Taxation, which became effective retroactively as of January 1, 2008, where a non-resident enterprise investor transfers equity interests in a PRC resident enterprise indirectly by way of disposing of equity interests in an overseas holding company, and such overseas holding company is located in a tax jurisdiction that: (i) has an effective tax rate less than 12.5% or (ii) does not tax foreign income of its residents, the non-resident enterprise investor should report such indirect transfer to the relevant tax authority of the PRC resident enterprise. The PRC tax authority will examine the true nature of the indirect transfer, and if the tax authority considers that the non-resident enterprise investor has adopted an abusive arrangement without a reasonable commercial purpose in order to reduce, avoid or defer PRC tax, they will disregard the existence of the overseas holding company that is used for tax planning purposes and re-characterize the indirect transfer. As a result, gains derived from such indirect transfer may be subject to PRC withholding tax at the rate of up to 10%. In addition, the PRC resident enterprise may be required to provide necessary assistance to support the enforcement of Circular 698.

There is some uncertainty as to the application of Circular 698. For example, the term “indirect transfer” is not clearly defined, and the relevant governmental authority has not yet promulgated any formal interpretations or declarations as to the process and format for reporting an indirect transfer to the competent tax authority, or on how to calculate the effective tax rates in a foreign tax jurisdiction or whether a non-resident enterprise investor has adopted an abusive arrangement in order to reduce, avoid or defer PRC tax. Although it appears that Circular 698 was not intended to apply to share transfers of publicly traded companies, there is uncertainty as to the application of Circular 698 to other indirect transfer of our PRC resident entities. As a result, we may have the risk of being subject to the reporting obligations or PRC tax under Circular 698 and may be required to expend resources to comply with Circular 698 or to establish that we should not be taxed under Circular 698, which may have an adverse effect on our financial condition and results of operations.

Risks Related to Our ADSs

The trading price of our ADSs has been volatile and may continue to be volatile regardless of our operating performance.

The trading price of our ADSs has been and may continue to be subject to wide fluctuations. The market price for our ADSs may continue to be volatile and subject to wide fluctuations in response to factors including the following:

| • |  | actual or anticipated fluctuations in our quarterly results of operations;

| • |  | changes in financial estimates by securities research analysts;

| • |  | conditions in internet search and online marketing markets;

| • |  | changes in the operating performance or market valuations of other internet search or internet companies;

| • |  | announcements by us or our competitors or other internet companies of new products, acquisitions, strategic partnerships, joint ventures or capital commitments;

| • |  | addition or departure of key personnel;

| • |  | fluctuations of exchange rates between RMB and the U.S. dollar;

34

##### Table of Contents

| • |  | intellectual property litigation; and

| • |  | general economic or political conditions in China or elsewhere in the world.

In addition, the stock market in general, and the market prices for internet-related companies and companies with operations in China in particular, have experienced volatility that often has been unrelated to the operating performance of such companies. The securities of some China-based companies that have listed their securities in the United States have experienced significant volatility since their initial public offerings in recent years, including, in some cases, substantial declines in the trading prices of their securities. The trading performances of these companies’ securities after their offerings may affect the attitudes of investors towards Chinese companies listed in the United States in general, which consequently may impact the trading performance of our ADSs, regardless of our actual operating performance. In addition, any negative news or perceptions about inadequate corporate governance practices or fraudulent accounting, corporate structure or other matters of other Chinese companies may also negatively affect the attitudes of investors towards Chinese companies in general, including us, regardless of whether we have engaged in any inappropriate activities. In particular, the global financial crisis and the ensuing economic recessions in many countries have contributed and may continue to contribute to extreme volatility in the global stock markets. These broad market and industry fluctuations may adversely affect the market price of our ADSs. Volatility or a lack of positive performance in our ADS price may also adversely affect our ability to retain key employees, most of whom have been granted options or other equity incentives.

Substantial future sales or the perception of sales of our ADSs in the public market could cause the price of our ADSs to decline.

Sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline. Such sales also might make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. If any existing shareholder or shareholders sell a substantial amount of ADSs, the prevailing market price for our ADSs could be adversely affected. In addition, if we pay for our future acquisitions in whole or in part with additionally issued ordinary shares, your ownership interests in our company would be diluted and this, in turn, could have a material and adverse effect on the price of our ADSs.

You may not have the same voting rights as the holders of our ordinary shares and may not receive voting materials in time to be able to exercise your right to vote.

Except as described in this annual report and in the deposit agreement, holders of our ADSs will not be able to exercise voting rights attached to the shares evidenced by our ADSs on an individual basis. Holders of our ADSs will appoint the depositary or its nominee as their representative to exercise the voting rights attached to the shares represented by the ADSs. You may not receive voting materials in time to instruct the depositary to vote, and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote. Upon our written request, the depositary will mail to you a shareholder meeting notice which contains, among other things, a statement as to the manner in which your voting instructions may be given, including an express indication that such instructions may be given or deemed given to the depositary to give a discretionary proxy to a person designated by us if no instructions are received by the depositary from you on or before the response date established by the depositary. However, no voting instruction will be deemed given and no such discretionary proxy will be given with respect to any matter as to which we inform the depositary that (i) we do not wish such proxy given, (ii) substantial opposition exists, or (iii) such matter materially and adversely affects the rights of shareholders.

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

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. Under the deposit agreement for the ADSs, the depositary will not offer those rights to ADS holders unless both

35

##### Table of Contents

the rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act of 1933, or exempt from registration under the Securities Act with respect to all holders of ADSs. We are under no obligation to file a registration statement with respect to any such rights or underlying securities or to endeavor to cause such a registration statement to be declared effective. In addition, we may not be able to take advantage of any exemptions from registration under the Securities Act. Accordingly, holders of our ADSs may be unable to participate in our rights offerings and may experience dilution in 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 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.

You may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. federal courts may be limited, because we are incorporated under Cayman Islands law, conduct most of our operations in China and all of our officers reside outside of the United States.

We are incorporated in the Cayman Islands, and conduct most of our operations in China through our subsidiaries and consolidated affiliated entities in China. All of our officers and a majority of our directors reside outside of the United States and some or all of the assets of these persons are located outside of the United States. As a result, it may not be possible to effect service of process within the United States or elsewhere outside of China upon our executive officers, including with respect to matters arising under U.S. federal securities laws or applicable state securities laws.

It may also be difficult or impossible for you to bring an action against us or against our directors and officers in the Cayman Islands or in China in the event that you believe that your rights have been infringed under the 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. There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits. Moreover, our PRC counsel has advised us that the PRC does not have treaties with the United States or many other countries providing for the reciprocal recognition and enforcement of judgment of courts.

Our corporate affairs are governed by our memorandum and articles of association and by the Companies Law (2013 Revision) and common law of the Cayman Islands. The rights of shareholders to take legal action against our directors and us, 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 English common law, which has persuasive, but not binding, authority 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 precedents in the United States. In particular, the Cayman Islands has a less developed body of securities laws as compared to the United States, and provides significantly less protection to investors. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action before the federal courts of the United States.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests through actions against our management, directors or major shareholders than would shareholders of a corporation incorporated in a jurisdiction in the United States.

##### Table of Contents

Our dual-class ordinary share structure with different voting rights 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. We issued Class A ordinary shares represented by our ADSs in our initial public offering. Our co-founder, chairman and chief executive officer, Robin Yanhong Li, who acquired our shares prior to our initial public offering, holds our Class B ordinary shares. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof, while Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Upon any transfer of Class B ordinary shares by a holder thereof to any person or entity which is not an affiliate of such holder, such Class B ordinary shares will be automatically and immediately converted into the equal number of Class A ordinary shares. In addition, if at any time Robin Yanhong Li and his affiliates collectively own less than 5% of the total number of the issued and outstanding Class B ordinary shares, each issued and outstanding Class B ordinary share will be automatically and immediately converted into one Class A ordinary share, and we shall not issue any Class B ordinary shares thereafter.

Due to the disparate voting powers attached to these two classes, certain shareholders have significant voting power over matters requiring shareholder approval, including election of directors and significant corporate transactions, such as a merger or sale of our company or our assets. This concentrated control could discourage or prevent others from pursuing any potential merger, takeover or other change of control transactions with our company, which could deprive our shareholders and ADS holders of an opportunity to receive a premium for their shares or ADSs as part of a sale of our company and might reduce the price of our ADSs.

Our articles of association contain anti-takeover provisions that could adversely affect the rights of holders of our ordinary shares and ADSs.

Our articles of association include certain provisions that could limit the ability of others to acquire control of our company, and therefore may deprive the holders of our ordinary shares and ADSs of the opportunity to sell their ordinary shares or ADSs at a premium over the prevailing market price by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transactions. These provisions include the following:

| • |  | A dual-class ordinary share structure.

| • |  | Our board of directors has the authority, without approval by the shareholders, to issue up to a total of 10,000,000 preferred shares in one or more series. Our board of directors may establish the number of shares to be included in each such series and may fix the designations, preferences, powers and other rights of the shares of a series of preferred shares.

| • |  | Our board of directors has the right to elect directors to fill a vacancy created by the increase of the board of directors or the resignation, death or removal of a director, which prevents shareholders from having the sole right to fill vacancies on our board of directors.

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal income tax consequence to U.S. Holders of our ADSs or ordinary shares.

Based on the market price of our ADSs and ordinary shares, the value of our assets, and the composition of our assets and income, we believe that we were not a “passive foreign investment company,” or PFIC, for our taxable year ended December 31, 2013, and we do not expect to be a PFIC for our taxable year ending December 31, 2014 or for the foreseeable future. A non-U.S. corporation will be considered a PFIC for any taxable year if either (i) at least 75% of its gross income is passive income or (ii) at least 50% of the value of its

37

##### Table of Contents

assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income. The value of our assets is generally determined by reference to the market price of the ADSs and ordinary shares, which may fluctuate considerably. In addition, because there are uncertainties in the application of the relevant rules and because PFIC status is a fact-intensive determination made on an annual basis, no assurance may be given with respect to our PFIC status for the current or any future taxable year.

If we were treated as a PFIC for any taxable year during which a U.S. Holder (defined below) held an ADS or an ordinary share, certain adverse U.S. federal income tax consequences could apply to the U.S. Holder. See “Item 10.E. Additional Information—Taxation—United States Federal Income Taxation—Passive Foreign Investment Company.”

Item 4. Information on the Company

A. History and Development of the Company

We were incorporated in the Cayman Islands in January 2000. Since our inception, we have conducted our operations in China principally through Baidu Online, our wholly owned subsidiary in Beijing, China. Since June 2001, we also have conducted part of our operations in China through Baidu Netcom, a consolidated affiliated entity in Beijing, China, which holds the licenses and approvals necessary to operate our websites and provide online advertising services. In more recent years, we have established additional subsidiaries inside and outside of China and assisted in establishing additional PRC consolidated affiliated entities to conduct part of our operations.

On August 5, 2005, we listed our ADSs on The NASDAQ National Market (later renamed The NASDAQ Global Market) under the symbol “BIDU.” We and certain selling shareholders of our company completed the initial public offering of 4,604,224 ADSs, each then representing one Class A ordinary share, on August 10, 2005. On May 12, 2010, we effected a change of the ADS to Class A ordinary share ratio from 1 ADS representing 1 Class A ordinary share to 10 ADSs representing 1 Class A ordinary share. The ratio change has the same effect as a 10-for-1 ADS split. Our ADSs currently trade on The NASDAQ Global Select Market.

In December 2008, our shareholders approved our name change from Baidu.com, Inc. to Baidu, Inc. In November 2009, we moved into our new corporate headquarters, which we name as Baidu Campus. Our principal executive offices are located at Baidu Campus, No. 10 Shangdi 10th Street, Haidian District, Beijing 100085, the People’s Republic of China. Our telephone number at this address is +86 (10) 5992-8888.

In July 2011, we acquired a majority stake in Qunar, an online travel search services provider, and have since then consolidated the financial results of Qunar in our consolidated financial statements. On November 1, 2013, Qunar listed its ADSs, each representing three Class B ordinary shares of Qunar, on the NASDAQ Global Market in connection with its initial public offering. We remain to be the majority shareholder of Qunar after its initial public offering.

In November 2012, we obtained the controlling interest in Qiyi.com, Inc., a prior equity method investee, and have since then consolidated its financial results into our consolidated financial statements. In May 2013, we acquired the online video business of PPStream Inc. and have merged it with iQiyi and have since then consolidated its financial results into our consolidated financial statements.

In October 2013, we acquired 100% equity interest of 91 Wireless from NetDragon Websoft Inc. and the other shareholders of 91 Wireless, and have since then consolidated its financial results into our consolidated financial statements.

B. Business Overview

We are the leading Chinese language internet search provider. As a technology-based media company, we aim to provide the best way for people to find information. In addition to serving users, we provide an effective platform for businesses to reach potential customers.

Our Baidu.com website was the largest website in China and the fifth largest website globally, as measured by average daily visitors and page views during the three-month period ended December 31, 2013, according to Alexa.com, an internet analytics firm. We are the most used internet search provider in China, capturing 81.6% of internet search traffic in China in 2013, according to iResearch Consulting Group, a market research firm. Our “Baidu” brand received the highest ranking for an internet brand in China in BrandZ Top 50 Most Valuable Chinese Brands 2013, a study published by Millward Brown Optimor, a brand strategy research firm.

We conduct our operations primarily in China, and our revenues generated from international operations are insignificant. Revenues generated from our operations in China accounted for approximately 99.6%, 99.5% and 99.8% of our total revenues in 2011, 2012 and 2013, respectively.

We serve three types of online participants:

Users. We offer a Chinese language search platform on our Baidu.com website that enables users to find relevant information online, including web pages, news, images, documents and multimedia files, through links provided on our website. We also offer several international products and services in local languages to users in several other countries.

We also provide a broad range of products and services to enrich user experience and facilitate easy and quick search, including search products, social-networking products, user-generated-content-based (UGC-based) knowledge products, location-based products and services, entertainment products, security products, mobile related products and services, products and services for developers and webmasters and other products and services. Our products and services can be accessed through PCs and mobile devices. We aspire to provide the best search experience to our users. To this end, we have invested in advanced technologies such as deep learning and semantic intelligence.

We also offer a broad range of mobile products, including Baidu Mobile Search, Baidu Mobile Maps, Baidu Mobile Assistant, 91 Assistant, HiMarket, Baidu Mobile Guardian, Baidu Mobile Browser, Baidu Photo Wonder and Baidu Yun.

Customers. We deliver online marketing services to a diverse customer base operating in a variety of industries. In 2013, we had approximately 753,000 active online marketing customers. Our online marketing customers consist of SMEs throughout China, large domestic companies and Chinese divisions and subsidiaries of large, multinational companies. We have a diverse customer base in terms of industries and geographical locations. Our defined industries in which our customers operate include medical and healthcare, education, software and online games, tourism and ticketing, machinery, construction and decoration, franchising, electronic commerce, electronic products, business services, transportation, financial services, information technology services, electronic components and household appliances. Customers in our top five industries contributed approximately 54% of our total online marketing revenues in 2013. Although we have customers located throughout China, we have a more active and larger customer base in coastal regions, reflecting the current general economic demographics in China.

We reach and serve our customers through our direct sales force as well as a network of third-party distributors across China. As many of our customers are SMEs, we use distributors to help us identify potential SME customers, collect payments and assist SMEs in setting up accounts with us and using our online marketing services. We have also engaged third-party agencies to identify and reach potential customers outside of China.

To enable our customers to effectively capture the mobile opportunity, we provide free tools to customers to help them build and modify mobile landing pages and proactively educate customers about mobile marketing. In May 2013, we introduced an integrated bidding system to better streamline the bidding experience on PC and mobile channels for our customers. Mobile Revenue exceeded 20% of our total revenues for the fourth quarter of 2013.

Baidu Union Members. Baidu Union consists of a large number of third-party web content, software and mobile application providers. Baidu Union members can display on their properties our customers’ promotional links that match the content of such members’ properties. Some Baidu Union members also embed some of our products and services into their properties. We allow Baidu Union members to provide high-quality and relevant search results to their users without the cost of building and maintaining advanced search capabilities in-house and to monetize their traffic through revenue sharing arrangements with us. We reward Baidu Union members which bring higher quality traffic to us by sharing with these members more revenues as a percentage of total revenues recognized by us. The number of Baidu Union members that contributed revenues to us decreased by approximately 14.4% in 2013. The decrease in Baidu Union members reflected our continuous efforts to optimize our quality of traffic, which caused the ceasation of cooperation with some union members.

Products and Services for Users

We focus on offering products and services that enable our users to find relevant information quickly and easily. We offer our main products and services to users through Baidu.com free of charge generally. These products and services can be accessed through PCs, mobile and other non-mobile devices.

The card contains the various attributes of the entity, sorted with relevancy and popularity. With the Knowledge graph, we can answer some queries directly through displaying accurate answers on the search result page. Given a query, the Knowledge graph can find not only the directly related knowledge entity but also some loosely related knowledge entities. Our search engine renders those loosely related entities in the right panel of the search result page, so as to motivate the user to search more. With the Knowledge graph, we reinforce the conversation between users and our search engine in order to better understand the need of users.

In addition, Baidu Web Search allows users to launch some applications directly, which feature is powered by Baidu Open Platform and Baidu Open Cloud where content providers and developers can submit their contents and applications.

Our distributors provide numerous services, including identifying customers, collecting payments, assisting customers in setting up accounts with us, suggesting keywords to maximize ROI and engaging in other marketing and educational services aimed at acquiring customers. We offer discounts to distributors as consideration for their services. We have relied on distributors for several reasons. Our P4P customer base in China is geographically diverse and fragmented, as many of our P4P customers are SMEs located in different regions in China. Moreover, SMEs are generally less experienced with online marketing as compared to large companies and therefore benefit from the extensive services provided by distributors. Finally, secure online payment and credit card systems are in early stages of development in China. Distributors serve as an important channel to reach SME customers throughout China and collect payments from them. We offer our online marketing services to medium and large corporate customers through third-party agencies and our direct sales force. We have also engaged third-party agencies to identify and reach the potential customers outside of China.

Marketing

We focus on continually improving the quality of our products and services, as we believe satisfied users and customers are more likely to recommend our products and services to others. Through these efforts and the increased use of internet in China, we have built our brand with modest marketing expenditures.

Our initial public offering in 2005 and subsequent positive media coverage have significantly enhanced our brand recognition. We have also implemented a number of marketing initiatives designed to promote our brand awareness among potential users, customers and Baidu Union members, and we invested significant resources on the promotion activities for our mobile products in last two years. For example, we have purchased advertising time on several television channels in China, cooperated with mobile device producers for our mobile products promotion, conducted cross-marketing activities with a number of leading consumer brands, conducted marketing activities targeted at specific types of users like students, launched localized marketing initiatives tailored to potential customers in various regions with the assistance of our distributors, organized and sponsored seminars and discussion forums targeted at existing and potential customers, conducted marketing activities aiming at keeping close relationships with website owners which are or may become Baidu Union members and educated new customers with tailored online or offline search engine marketing trainings to strengthen their search engine marketing abilities in 2012. In 2013, we successfully hosted the second annual “Baidu Moments Marketing Ceremony,” introducing the “branding moments” marketing theory, and also worked with Millward Brown ACSR, a market survey institution, to release the “Brand Digital Asset”, which evaluated the performance of brands in the digital field. In the meanwhile, we continued to implement a number of marketing initiatives designed to promote awareness of mobile marketing and Light App-based new marketing methods.

In addition, Qihoo 360, a company operating an internet platform and primarily providing security products, launched its search services in 2012 and competes with us on internet search.

Other Advertising Media. Other advertising media, such as newspapers, yellow pages, magazines, billboards, other forms of outdoor media, television, radio and mobile applications compete for a share of our customers’ marketing budgets. Large enterprises currently spend a relatively small percentage of their marketing budgets on online marketing as compared to other advertising media.

Technology

We have developed a proprietary technological infrastructure consisting of technologies for web search, mobile, P4P, targetizement and large-scale systems. Our established infrastructure serves as the backbone for both our PC and mobile platforms.

In January 2013, we established the Baidu Institute of Deep Learning. Deep learning is an emerging computer science field that seeks to mimic the human brain with hardware and software. This technology has helped us develop cutting-edge speech and image recognition technologies, enhance the search experience we provide to users and improve our ad targeting technology and monetization capability.

Web Search Technology

Our web search technology applies a combination of techniques to determine the importance of a web page independent of any particular search query and the relevance of that page to a particular search query.

Link Analysis Techniques. Link analysis is a technique that determines the relevance between a user query and a web page by evaluating the combination of the anchor texts and the number of web pages linked to that web page. We treat a link from web page A to web page B as a “vote” by page A in favor of page B. The subject of the “vote” is described in the anchor texts of that link. The more “votes” a web page gets, the higher the relevance. We compare search queries with the content of web pages to help determine relevance. Our text-based scoring techniques do more than just counting the number of times a search term appears on a web page. For example, our technology determines the proximity of individual search terms to each other on a given web page, and prioritizes results where the search terms are near each other. Other aspects of a page’s content are also considered. By combining link analysis with our information extraction techniques, we are able to deliver relevant search results.

Information Extraction Techniques. We extract information from a web page using high performance algorithms and information extraction techniques. Our techniques enable us to understand web page content,

52

##### Table of Contents

delete extraneous data, build link structures, identify duplicate and junk pages and decide whether to include or exclude a web page based on its quality. Our techniques can process millions of web pages quickly. In addition, our anti-spam algorithms and tools can identify and respond to spam web pages quickly and effectively.

Web Crawling Techniques. Our powerful computer clusters and intelligent scheduling algorithms allow us to crawl web pages efficiently. We can easily scale up our system to collect an ever-growing number of Chinese web pages. Our spider technology enables us to refresh web indices at intervals ranging from every few minutes to every few weeks. We set the index refresh frequency based on our knowledge of internet search users’ needs and the nature of the information. For example, our news index is typically updated every five minutes, and can be as frequent as every minute, throughout the day given the importance of timely information for news. We also mine multimedia and other forms of files from web page repositories.

Our Project Aladdin, an ongoing research and development project, aims at uncovering useful information of the “Hidden Web,” which usually refers to the invisible database of the numerous websites and the part of the internet that traditional search engine technology may not be able to index. The resulted Aladdin platform enriches our search index and hence provides richer search results to our users. In 2012, we made a major upgrade to the Aladdin platform, which not only provides a better and faster way to integrate new “hidden web” information into our search index, but also revolutionizes the search result presentation of the left side of the search result page. Furthermore, the upgraded platform integrates our knowledge graph to render highly relevant “knowledge panel” at the right side of the search result page to encourage users to acquire more knowledge or take actions directly within the page. Aladdin has become Baidu Open Platform. With Aladdin, mobile application developers do not have to construct and manage websites, and can therefore focus on improving their mobile applications. Aladdin can help incubate websites without webpages.

Natural Language Processing Techniques. We analyze and understand user queries and web pages by using various natural language processing techniques, including, among others, word segmentation, named entity recognition, syntax and semantic analysis, paraphrasing and language dependent encoding. For example, we can identify Chinese names on a web page. When a user searches for a person based on the person’s Chinese name, we can display the web pages that are specifically related to that person. We also mine user behavior and search interests from our large search query logs. We provide additional web search features such as advanced search, spelling check and search by Chinese phonetics (Pinyin).

Multimedia Technologies. We work on developing intelligent algorithms and systems to better understand human spoken languages, identify audio contents, and recognize the meaning of images and videos. These technologies will enable users to access information in a most natural way, and help our search engine better organize the vast amount of multimedia contents on the web. For example, our speech recognition technology has been applied to our mobile search on smartphones, and our face recognition technology has been applied to generate relevant photos when a person is searched. In 2013, we launched our similar image search engine, which can recognize the object and scene in the image that users want to search for and return an image that contains the most similar object and scene.

Mobile Search Technology. In order to improve search relevance and user experience on mobile devices, we made big progress on mobilizing standard web pages. Through mobilizing standard web pages technology we analyze the content and features of web pages for PCs, and automatically convert such pages to the layouts suitable for mobile devices. The technology also allows users to view the pages in an efficient way, with less time and less traffic consumed. We have also adopted the web app technology of LightApp for mobile searches, which technology allows us to crawl the information and services that regular crawlers cannot get, and present them in a way suitable for mobile devices.

P4P Technology

Our P4P platform serves billions of relevant, targeted sponsored links each day based on search terms users enter or content they view on the web page. Our key P4P technology includes:

P4P Auction System. We use a web-based auction system to enable customers to bid for positions and automatically deliver relevant, targeted promotional links on Baidu’s properties and Baidu Union members’ properties. The system starts by screening the relevance between the sponsored links and a particular query. Our intelligent ranking system takes into consideration the quality factor of a sponsored link for a search query in addition to the price bid on the keyword. The quality factor of a sponsored link for a search query is determined based on the relevance and certain other factors. The relevance is determined based on the analysis of past search and click-through results. Links to customers’ websites are ranked according to a comprehensive ranking index, calculated based on both the quality factor of a sponsored link for a search query and the price bid on that keyword. We employ a dynamic mechanism in determining the minimum bidding price for each keyword.

One of our current online marketing systems, Phoenix Nest, is designed to generate more relevant results, compared with the previous auction-based online marketing system we used before December 2009. Phoenix Nest helps customers more easily find users’ favorite search terms to bid on, and provides customers with more tools for budget management and more data for the effective measurement of ROI. We have been continually improving our click-through rate (CTR) estimation technology, for example, we have introduced deep neutral network (DNN) technology into our CTR estimation,

P4P Billing System. We record every click and charge customers a fee by multiplying the number of clicks by the cost per click. Our system is designed to detect fraudulent clicks based on factors such as click patterns and timestamps. This system also computes the amount a Baidu Union member or a distributor should be paid. The billing information is integrated with our internal Oracle ERP financial system.

P4P Customer Service System. This system offers data and tools to analyze data for our customers to evaluate and optimize the performance of our online marketing services provided to them. Through this system, our customers can also manage information relating to online marketing services such as their budgets and time periods for the services.

ProTheme Contextual Promotion Technology. Our ProTheme technology employs techniques that consider factors such as theme finding, keyword analysis, word frequency and the overall link structure of the web to analyze the content of individual web pages and to match sponsored links in our P4P platform to the web pages almost instantaneously. With this targeting technology, we can automatically provide contextually relevant promotional links. For example, our technology can provide links offering tickets to fans of a specific sports team or a news story about that team.

Targetizement Technology

Our Targetizement technology matches our customers’ promotional links with their targeted internet users. Our automatic algorithm can analyze a user’s audience attributes based on his or her past search experience and display promotional links that the user may be interested in viewing.

Large-Scale Systems and Technologies

We generally develop custom software for our products or services that are running on clusters of commodity hardware. Our investment in large-scale system infrastructure produces several key benefits: reduction in cost of storing and processing large amounts of data, simplification of deployment and operation of large-scale products and services, and automation of administration tasks of large-scale clusters of computers. Moreover, our infrastructure can be easily scaled to deal with traffic growth and data volume increase.

##### Table of Contents

Our large-scale system infrastructure uses distributed software and high performance parallel computing technologies. It provides high-quality web search services and web page collections using cost-effective servers running linux operating system. We have management information systems that enable us to perform tasks such as service operations, administration, and trouble-shooting very efficiently. In addition, we have developed framework that can help us conduct live effect test of new ideas without affecting major live services.

Our infrastructure significantly improves the relevance between a user query and marketing results by using advanced search and information retrieval algorithms that are computationally intensive. Our infrastructure also shortens our product development life cycle and allows us to innovate more quickly and cost-effectively. We constantly evaluate new hardware alternatives and software techniques to further reduce our infrastructure cost.

Intellectual Property

We rely on a combination of trademark, copyright and trade secret protection laws in China and other jurisdictions, as well as confidentiality procedures and contractual provisions to protect our intellectual property and our brand. We have 154 issued patents in China and intend to apply for more patents to protect our core technologies. We also enter into confidentiality, non-compete and invention assignment agreements with our employees and consultants and nondisclosure agreements with selected third parties. “ ”, our company’s name “Baidu” in Chinese, has been recognized as a well-known trademark in China by the Trademark Office under the State Administration for Industry and Commerce. In addition to owning the trademark “ ” and the related logo, we have applied for registration of additional trademarks and logos, including “ Hi” and “ ”. We also have registered certain trademarks in Hong Kong, including “ ” and our company logo, in the United States, including “Baidu”, in Singapore and Indonesia, including our company logo. In addition, we have registered our domain name Baidu.com, hao123.com and baifubao.com with MarkMonitor.com, Baidu.jp with humeia.co.jp and Baidu.cn, Baidu.com.cn, and certain other websites with China National Network Information Center, or CNNIC.

Internet, technology and media companies are frequently involved in litigation based on allegations of infringement or other violations of intellectual property rights. Furthermore, the application of laws governing intellectual property rights in China and abroad is uncertain and evolving and could involve substantial risks to us. See “Item 3.D. Key Information—Risk Factors—Risks Related to Our Business—We may face intellectual property infringement claims and other related claims that could be time-consuming and costly to defend and may result in an adverse impact over our operations” and “—We may be subject to patent infringement claims with respect to our P4P platform.”

Regulation

The PRC government extensively regulates the telecommunications industry, including the internet sector. The State Council, the MIIT and other relevant government authorities have promulgated an extensive regulatory scheme governing internet-related services. This section summarizes the principal PRC laws and regulations relating to our business.

In the opinion of Han Kun Law Offices, our PRC legal counsel, (i) the ownership structure relating to our consolidated affiliated entities complies with current PRC laws and regulations; (ii) subject to the disclosure and risks disclosed under “Item 3.D. Key Information—Risk Factors—Risks Related to Our Corporate Structure,”“—Risks Related to Doing Business in China” and “—Regulation,” our contractual arrangements with our consolidated affiliated entities and the nominee shareholders are valid and binding on all parties to these arrangements and do not violate current PRC laws or regulations; and (iii) subject to the disclosure and risks disclosed under “Item 3.D. Key Information—Risk Factors—Risks Related to Our Corporate Structure,”“—Risks Related to Doing Business in China” and “—Regulation,” the business operations of our consolidated affiliated entities, as described herein, comply with current PRC laws and regulations in all material respects.

China’s internet industry and online advertising market are evolving. There are substantial uncertainties regarding the interpretation and application of existing or proposed PRC laws and regulations. We cannot assure you that the PRC regulatory authorities would find that our corporate structure and our business operations comply with PRC laws and regulations. If the PRC government finds us to be in violation of PRC laws and regulations, we may be required to pay fines and penalties, obtain certain licenses or permits and change, suspend or discontinue our business operations until we comply with applicable PRC laws and regulations.

Regulations on Value-Added Telecommunications Services and Internet Content Services

Internet content services. The Telecommunications Regulations promulgated by the PRC State Council in September 2000 categorize all telecommunications businesses in the PRC as either basic or value-added. Internet content services, or ICP services, are classified as value-added telecommunications businesses. Pursuant to the Telecommunications Regulations, commercial operators of value-added telecommunications services must first obtain an operating license from the MIIT or its provincial level counterparts. The Administrative Measures on Internet Information Services, also promulgated by the PRC State Council in September 2000, require companies engaged in the provision of commercial internet content services to obtain an ICP license from the relevant government authorities before providing any commercial internet content services within the PRC. “Commercial internet content services” generally refer to provision of information, webpage production and other services through internet for a fee. We do not believe our P4P services are categorized as part of internet content services that require an ICP license under these regulations. Although our PRC subsidiary Baidu Online conducts the P4P business by, among other things, designing P4P keywords, interacting with potential P4P customers and engaging in sales activities with our customers, P4P search results are displayed on the websites operated by Baidu Netcom, including baidu.com. Baidu Netcom, as the owner of our domain name baidu.com and holder of the necessary licenses and approvals, such as an ICP license, operates the website to display P4P search results and other marketing content.

The Administrative Measures for Telecommunications Business Operating License, promulgated by the MIIT with latest amendments becoming effective in April 2009, set forth the types of licenses required for value-added telecommunications services and the qualifications and procedures for obtaining such licenses. For example, a value-added telecommunications service operator providing commercial value-added services in multiple provinces is required to obtain an inter-regional license, whereas a value-added telecommunications service operator providing the same services in one province is required to obtain a local license.

BBS services. The Internet Electronic Messaging Service Administrative Measures promulgated by the MIIT in November 2000 require ICP operators to obtain specific approvals before providing BBS services. BBS services include electronic bulletin boards, electronic forums, message boards and chat rooms. On July 4, 2010, the approval requirement for operating BBS services was terminated by a decision issued by the PRC State Council. However, in practice, the competent authorities in Beijing still require the relevant operating companies to obtain such approval for the operation of BBS services.

Content regulation. National security considerations are an important factor in the regulation of internet content in China. The National People’s Congress, the PRC’s national legislature, has enacted laws with respect to maintaining the security of internet operation and internet content. Under these laws and applicable regulations, violators may be subject to penalties, including criminal sanctions, for internet content that:

| • |  | opposes the fundamental principles stated in the PRC constitution;

| • |  | compromises national security, divulges state secrets, subverts state power or damages national unity;

| • |  | harms the dignity or interests of the state;

| • |  | incites ethnic hatred or racial discrimination or damages inter-ethnic unity;

| • |  | undermines the PRC’s religious policy or propagates heretical teachings or feudal superstitions;

56

##### Table of Contents

| • |  | disseminates rumors, disturbs social order or disrupts social stability;

| • |  | disseminates obscenity or pornography, encourages gambling, violence, murder or fear or incites the commission of a crime;

| • |  | insults or slanders a third party or infringes upon the lawful rights and interests of a third party; or

| • |  | is otherwise prohibited by law or administrative regulations.

ICP operators are required to monitor their websites, including electronic bulletin boards. They may not post or disseminate any content that falls within the prohibited categories and must remove any such content from their websites. The PRC government may shut down the websites of ICP license holders that violate any of the above-mentioned content restrictions and revoke their ICP licenses.

Restrictions on Foreign Ownership in Value-Added Telecommunications Services

Pursuant to the Provisions on Administration of Foreign-Invested Telecommunications Enterprises, promulgated by the PRC State Council with latest amendments becoming effective in September 2008, the ultimate foreign equity ownership in a value-added telecommunications services provider must not exceed 50%. In order to acquire any equity interest in a value-added telecommunication business in China, a foreign investor 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 Ministry of Commerce’s authorized local counterparts), which retain considerable discretion in granting approvals. According to publicly available information, the PRC government has issued telecommunications business operating licenses to only a limited number of foreign-invested companies, all of which are Sino-foreign joint ventures engaging in the value-added telecommunication business. We believe that it would be impracticable for us to acquire any equity interest in our consolidated affiliated entities without diverting management attention and resources. Moreover, we believe that our contractual arrangements with these entities and the individual nominee shareholders provide us with sufficient and effective control over these entities. Accordingly, we currently do not plan to acquire any equity interest in any of these entities.

An Notice on Intensifying the Administration of Foreign Investment in Value-added Telecommunications Services, issued by the MIIT in July 2006, prohibits domestic telecommunication services 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. Pursuant to this notice, either the holder of a Value-Added Telecommunication Business Operating License 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 further requires each license holder to have the necessary facilities, including servers, for its approved business operations and to maintain the facilities in the regions covered by its license. If a license holder fails to comply with the requirements in the notice and cure such non-compliance, the MIIT or its local counterparts have the discretion to take measures against such license holders, including revoking their Value-Added Telecommunication Business Operating Licenses.

Due to the restrictions under these PRC regulations, we operate our websites mainly through Baidu Netcom and Beijing Perusal, and operate an online payment platform through BaiduPay. Baidu Netcom, Beijing Perusal and BaiduPay are our PRC consolidated affiliated entities, and are considered domestic PRC entities under PRC law given that the nominee shareholders are PRC citizens or PRC entities. Each of Baidu Netcom, Beijing Perusal, BaiduPay and some of our other PRC consolidated affiliated entities holds a Value-Added Telecommunications Business Operating License. In compliance with the Notice of the MIIT on Intensifying the Administration of Foreign Investment in Value-added Telecommunications Services, Baidu Netcom, Beijing Perusal and BaiduPay, our consolidated affiliated entities, own the necessary domain names and trademarks,

including pending trademark applications and have the necessary personnel and facilities to operate our websites. It remains unclear whether the provision of online payment services by BaiduPay will require BaiduPay to apply for a Value-Added Telecommunications Business Operating License for “online data processing and transaction processing businesses” as provided in the Catalog of Telecommunications Businesses promulgated by the MIIT, although in practice many companies conducting such business do not apply for such license.

Regulations on News Display

Displaying news on a website and disseminating news through the internet are highly regulated in the PRC. The Provisional Measures for Administrating Internet Websites Carrying on the News Displaying Business, jointly promulgated by the State Council News Office and the MIIT in November 2000, require an ICP operator (other than a government authorized news unit) to obtain State Council News Office approval to post news on its website or disseminate news through the internet. Furthermore, the disseminated news must come from government-approved sources pursuant to contracts between the ICP operator and the sources, copies of which must be filed with the relevant government authorities.

In September 2005, the State Council News Office and the MIIT jointly issued the Provisions on the Administration of Internet News Information Services, requiring internet news information service organizations to provide services as approved by the State Council News Office, subject to annual inspection under the provisions. Pursuant to the provisions, no internet news information service organizations may take the form of a foreign-invested enterprise, whether a joint venture or a wholly foreign-owned enterprise, and no cooperation between internet news information service organizations and foreign-invested enterprises is allowed prior to the security evaluation by the State Council News Office.

Baidu Netcom obtained the Internet News License, which permits it to publish internet news pursuant to the relevant PRC laws and regulations, in December 2006, and had the license renewed in June 2010. The Internet News License is subject to annual inspection by relevant government authorities.

Regulations on Internet Drug Information Services

According to the Measures for the Administration of Internet Drug Information Services, issued by the State Food and Drug Administration in July 2004, an ICP operator publishing drug-related information must obtain a qualification certificate from the State Food and Drug Administration or its provincial level counterpart.

Baidu Netcom obtained the Qualification Certificate for Internet Drug Information Services, which permits it to publish drug-related information on its website, in November 2007, and had the certificate renewed in September 2012. We have another entity in our group that has obtained the Qualification Certificate for Internet Drug Information Services.

Regulations on Internet Culture Activities

The amended Internet Culture Administration Measures, promulgated by the Ministry of Culture and becoming effective in April 2011, require ICP operators engaging in “internet culture activities” to obtain a permit from the Ministry of Culture. The “internet culture activities” include, among other things, online dissemination of internet cultural products (such as audio-video products, games, performances of plays or programs, works of art and cartoons) and the production, reproduction, importation, distribution and broadcasting of internet cultural products. Imported internet cultural products are subject to content review by the Ministry of Culture before they are disseminated online, while domestic internet cultural products must be filed with the local branch of the Ministry of Culture within 30 days following the online dissemination. Baidu Netcom was granted an Internet Culture Business Permit in April 2007, which was renewed again recently in November 2013. Beijing Perusal and some other entities in our group were also granted an Internet Culture Business Permit.

The Several Suggestions on the Development and Administration of the Internet Music, issued by the Ministry of Culture and becoming effective in November 2006, reiterate the requirement for the internet service provider to obtain the Internet Culture Business Permit to carry on any business of internet music products. In addition, foreign investors are prohibited from engaging in the internet culture business operation.

Furthermore, the Notice on Strengthening and Improving the Content Review of Online Music, issued by Ministry of Culture in August 2009, provides that only “internet culture operating entities” approved by the Ministry of Culture may engage in the production, release, dissemination (including providing direct links to music products) and importation of online music products. Internet culture operating entities should establish strict self-monitoring system of online music content and set up special department in charge of such monitoring.

Regulations on Internet Publishing

The Interim Provisions for the Administration of Internet Publishing, jointly issued by the GAPP and the MIIT and becoming effective in August 2002, require entities that engage in internet publishing to obtain approval from the GAPP. Pursuant to the provisions, “internet publishing” refers to the act of online spreading of articles, whereby the internet information service providers select, edit and process works created by themselves or others and subsequently post such works on the internet or transmit such works to the users’ end through internet for the public to browse, read, use or download. Baidu Netcom is in the process of applying for the Internet Publication License. We have an entity in our group that holds an Internet Publication License, which is valid from November 2011 to November 2016. Another entity in our group is also in the process of applying for the Internet Publication License.

Regulation on Broadcasting Audio/Video Programs through the Internet

In July 2004, the State Administration of Radio Film and Television promulgated the Rules for the Administration of Broadcasting of Audio/Video Programs through the Internet and Other Information Networks, or the Audio/Video Broadcasting Rules. The Audio/Video Broadcasting Rules apply to the opening, broadcasting, integration, transmission or download of audio/video programs through internet and other information networks. Anyone who wishes to engage in internet broadcasting activities must first obtain an Online Audio/Video Program Transmission License, with a term of two years, issued by the State Administration of Radio Film and Television and operate in accordance with the scope as stipulated in such license. Foreign-invested enterprises are not allowed to engage in the above-mentioned business activities.

The Rules for the Administration of Internet Audio and Video Program Services, commonly known as Document 56, jointly promulgated by the State Administration of Radio Film and Television and the MIIT in December 2007, reiterate the requirement set forth in the Audio/Video Broadcasting Rules that online audio/video service provider must obtain a license from the State Administration of Radio Film and Television. Furthermore, Document 56 requires all online audio/video service providers to be either wholly state-owned or state-controlled. According to some official answers to press inquiries published on the State Administration of Radio Film and Television’s website in February 2008, officials from the State Administration of Radio Film and Television and the MIIT clarified that online audio/video service providers that already had been operating lawfully prior to the issuance of Document 56 may re-register and continue to operate without becoming state-owned or controlled, provided that the providers have not engaged in any unlawful activities. This exemption will not be granted to online audio/video service providers established after Document 56 was issued. Baidu Netcom has renewed its Online Audio/Video Program Transmission License, which is valid from July 2012 to July 2015, iQiyi has an Online Audio/Video Program Transmission License valid from October 2012 to October 2015, and another entity in our group has an Online Audio/Video Program Transmission License valid from March 2011 to March 2014.

Regulations on Payment Services by Non-financial Institutions

Pursuant to the People’s Bank of China’s Measures Concerning Payment Services by Non-financial Institutions, which took effect in September 2010, and its implementation rules, non-financial institutions that have been providing monetary transfer services as an intermediary between payees and payers, including online payment, issuance and acceptance of prepaid card or bank card, and other payment services as specified by the People’s Bank of China, must obtain a license from the People’s Bank of China prior to September 1, 2011, in order to continue providing monetary transfer services. BaiduPay applied for the license after the regulations mentioned above were promulgated and prior to September 1, 2011, and was granted the license for online payment in July 2013.

Regulations on Internet Map Services

According to the Administrative Rules of Surveying Qualification Certificate and the amended Standard for Internet Map Services issued by the National Administration of Surveying, Mapping and Geoinformation (formerly known as the State Bureau of Surveying and Mapping) in March 2009 and May 2010, respectively, the provision of internet map services by any non-surveying and mapping enterprise is subject to the approval of the National Administration of Surveying, Mapping and Geoinformation and requires a Surveying and Mapping Qualification Certificate. Internet maps refer to maps called or transmitted through internet. Pursuant to the Notice on Further Strengthening the Administration of Internet Map Services Qualification issued by the National Administration of Surveying, Mapping and Geoinformation in December 2011, any entity without applying for a Surveying and Mapping Qualification Certificate for internet map services is prohibited from providing any internet map services. Baidu Netcom currently provides online traffic information inquiry services as well as internet map services and has obtained a Surveying and Mapping Qualification Certificate for internet map services. Another entity in our group has also obtained the Surveying and Mapping Qualification Certificate.

Regulations on Online Games

Pursuant to the Interim Provisions for the Administration of Internet Publishing, the online games services provided on our websites by our online game operator partners may be deemed as a type of “internet publication” provided by us, and we may be required to obtain an Internet Publication License from the GAPP. Baidu Netcom is still in the process of applying for the Internet Publication License. We have an entity in our group that holds an Internet Publication License, and another entity also in the process of applying for the Internet Publication License. The required approval by the GAPP of each online game provided on our websites is handled by our online game operator partners.

In June 2010, the Ministry of Culture promulgated the Interim Administration Measures of Online Games. In accordance with these measures, an ICP service provider operating online games, must obtain an Internet Culture Business Permit. Baidu Netcom and some other entities in our group have obtained an Internet Culture Business Permit for operating online games. These measures also specify that the Ministry of Culture is responsible for the censorship of imported online games and the filing of records of domestic online games. The procedures for the filing of records of domestic online games must be conducted with the Ministry of Culture within 30 days after the commencement date of the online operation of such online games or the occurrence date of any material alteration of such online games. The approval by or filing with the Ministry of Culture of each online game provided on our websites has been handled primarily by our online game operator partners.

In September 2009, the GAPP (currently known as SAPPRFT) together with several other government agencies issued a Circular 13, which explicitly prohibits foreign investors from participating in online game operating businesses through wholly-owned enterprises, equity joint ventures or cooperative joint ventures in China. The Circular 13 expressly prohibits foreigninvestors from gaining control over or participating in PRC operating companies’ online game operations through indirect means, such as establishing joint venture

##### Table of Contents

companies, entering into contractual arrangements with or providing technical support to the operating companies, or through a disguised form, such as incorporating user registration, user account management or payment through game cards into online game platforms that are ultimately controlled or owned by foreign investors. We offer online games provided by our game operator partners on our websites owned and operated by our consolidated affiliated entities. We have also acquired 91 Wireless, which operates two leading smartphone application distribution platforms in China as well as a mobile game platform through our consolidated affiliated entities. If our contractual arrangements were deemed to be “indirect means” or “disguised form” under the Circular 13, our relevant contractual arrangements may be challenged by the SAPPRFT or other governmental authorities. If we were found to be in violation of the Circular 13 to operate our mobile game platform, the SAPPRFT, in conjunction with relevant regulatory authorities, would have the power to investigate and deal with such violations, including in the most serious cases, suspending and revoking the relevant licenses and registrations.

Regulations on Online Game Virtual Currency

The Interim Administration Measures of Online Games require companies that (i) issue online game virtual currency (including prepaid cards and/or pre-payment or prepaid card points), or (ii) offer online game virtual currency transaction services to apply for the Internet Culture Business Permit from provincial branches of the Ministry of Culture. The regulations prohibit companies that issue online game virtual currency from providing services that would enable the trading of such virtual currency. Any company that fails to submit the requisite application will be subject to sanctions, including but not limited to termination of operation, confiscation of incomes and fines. The regulations also prohibit online game operators from allocating virtual items or virtual currency to players based on random selection through lucky draw, wager or lottery that involves cash or virtual currency directly paid by the players. In addition, companies that issue online game virtual currency must comply with certain specific requirements, for example, online games virtual currency can only be used for products and services related to the issuance company’s own online games. Baidu Netcom and some other entities in our group have obtained the Internet Culture Business Permit for issuing online game virtual currency.

Regulations on Advertisements

The PRC government regulates advertising, including online advertising, principally through the State Administration for Industry and Commerce, although there are no national PRC laws or regulations regulating online advertising business specifically. Under the Rules for Administration of Foreign-Invested Advertising Enterprise, promulgated by the State Administration for Industry and Commerce and the Ministry of Commerce in March 2004 and amended in October 2008, foreign investors are permitted to own equity interests in PRC advertising companies. However, foreign investors in wholly foreign-owned and joint venture advertising companies are required to have at least three years and two years, respectively, of direct operations in the advertising industry outside of China. The Administrative Regulations for Advertising Operation Licenses, taking effect in January 2005, exempt enterprises (other than radio stations, television stations, newspapers and magazines, non-corporate entities and other specified entities) from the previous requirement to obtain an advertising operation license in addition to a business license.

We conduct our online advertising business through our consolidated affiliated entities in China, Baidu Netcom and Beijing Perusal, each of which holds a business license that covers online advertising in its business scope. Our subsidiaries Baidu Times and Baidu China have also expanded their respective business license to cover advertising in their respective business scope.

Advertisers, advertising operators and advertising distributors are required by PRC advertising laws and regulations to ensure that the contents of the advertisements they prepare or distribute are true and in full compliance with applicable laws and regulations. In addition, where a special government review is required for certain categories of advertisements before publishing, the advertisers, advertising operators and advertising distributors are obligated to confirm that such review has been performed and the relevant approval has been

##### Table of Contents

obtained. Violation of these regulations may result in penalties, including fines, confiscation of advertising income, orders to cease dissemination of the advertisements and orders to publish an advertisement correcting the misleading information. In the case of serious violations, the State Administration for Industry and Commerce or its local branches may force the violator to terminate its advertising operation or even revoke its business license. Furthermore, advertisers, advertising operators or advertising distributors may be subject to civil liability if they infringe on the legal rights and interests of third parties.

Tort Liability Law

In accordance with the PRC Tort Liability Law, which became effective in July 2010, internet users and internet service providers bear tortious liabilities in the event that they infringe upon other persons’ rights and interests through the internet. Where an internet user conducts tortious acts through internet services, the infringed person has the right to request the internet service provider take necessary actions such as deleting contents, screening and de-linking. Failing to take necessary actions after being informed, the internet service provider will be subject to joint and several liabilities with the internet user with regard to the additional damages incurred. Where an internet service provider knows that an internet user is infringing upon other persons’ rights and interests through its internet service but fails to take necessary actions, it is jointly and severally liable with the internet user.

Regulations on Intellectual Property Rights

China has adopted legislation governing intellectual property rights, including patents, copyrights, trademarks, and domain names.

Patent. The PRC Patent Law provides for patentable inventions, utility models and designs, which must meet three conditions: novelty, inventiveness and practical applicability. The State Intellectual Property Office under the State Council is responsible for examining and approving patent applications. A patent is valid for a term of twenty years in the case of an invention and a term of ten years in the case of utility models and designs.

Copyright. The PRC Copyright Law and its implementation rules extend copyright protection to products disseminated over the internet and computer software. There is a voluntary registration system administered by the China Copyright Protection Center. Creators of protected works enjoy personal and property rights, including, among others, the right of disseminating the works through information network.

Pursuant to the relevant PRC regulations, rules and interpretations, ICP operators will be jointly liable with the infringer if they (i) participate in, assist in or abet infringing activities committed by any other person through the internet, (ii) are or should be aware of the infringing activities committed by their website users through the internet, or (iii) fail to remove infringing content or take other action to eliminate infringing consequences after receiving a warning with evidence of such infringing activities from the copyright holder. The court will determine whether an internet service provider should have known of their internet users’ infringing activities based on how obvious the infringing activities are by taking into consideration a number of factors, including (i) the information management capabilities that the provider should have based on the possibility that the services provided by it may trigger infringing acts, (ii) the degree of obviousness of the infringing content, (iii) whether it has taken the initiative to select, edit, modify or recommend the contents involved, (iv) whether it has taken positive and reasonable measures against infringing acts, and (v) whether it has set up convenient programs to receive notices of infringement and made timely and reasonable responses to the notices. Where an internet service provider has directly obtained economic benefits from any contents made available by an internet user, it shall have a higher duty of care with respect to the internet user’s act of infringement of others’ copyrights. Advertisements placed for or other benefits particularly connected with specific contents may be deemed as direct economic benefits from such contents, but general advertising fees or service fees charged by an internet service provider for its internet services will not be included. In addition, where an ICP operator is clearly aware of the infringement of certain content against another’s copyright through the internet, or fails to

62

##### Table of Contents

take measures to remove relevant contents upon receipt of the copyright holder’s notice, and as a result, it damages the public interest, the ICP operator could be ordered to stop the tortious act and be subject to other administrative penalties such as confiscation of illegal income and fines. An ICP operator is also required to retain all infringement notices for a minimum of six months and to record the content, display time and IP addresses or the domain names related to the infringement for a minimum of 60 days.

An internet service provider may be exempted from liabilities for providing links to infringing or illegal content or providing other internet services which are used by its users to infringe others’ copyright, if it does not know and does not have constructive knowledge that such content is infringing upon other parties’ rights or is illegal. However, if the legitimate owner of the content notifies the internet service provider and requests removal of the links to the infringing content, the internet service provider would be deemed to have constructive knowledge upon receipt of such notification, but would be exempted from liabilities if it removes or disconnects the links to the infringing content at the request of the legitimate owner. At the request of the alleged infringer, the internet service provider should immediately restore links to content previously disconnected upon receipt of initial non-infringing evidence.

We have adopted measures to mitigate copyright infringement risks. For example, our policy is to remove links to web pages and materials uploaded by the users if we know these web pages or materials contain materials that infringe upon third-party rights or if we are notified by the legitimate copyright holder of the infringement with proper evidence.

Software Products. The amended Administrative Measures on Software Products, promulgated by the MIIT and becoming effective in April 2009, provide a registration and filing system with respect to software products made in or imported into China. Software products may be registered with the relevant local authorities in charge of software industry administration. Registered software products may enjoy preferential treatment status granted by applicable software industry regulations. Software products can be registered for five years, and the registration is renewable upon expiration.

In addition, the Computer Software Protection Regulations and the Computer Software Copyright Registration Procedures apply to software copyright registration, license agreement registration and transfer agreement registration. Although such registration is not mandatory under PRC law, software copyright owners are encouraged to go through the registration process and registered software may receive better protection.

Trademark. The PRC Trademark Law and its implementation rules protect registered trademarks. The Trademark Office under the State Administration for Industry and Commerce handles trademark registrations and grants a term of ten years to registered trademarks. Trademark license agreements must be filed with the Trademark Office for record. “ ” is recognized as a well-known trademark in China by the Trademark Office under the State Administration for Industry and Commerce. In addition to owning the trademark “ ” and the related logo, we have applied for registration of additional trademarks and logos, including “ Hi” and “ ”.

Domain name. Domain names are protected under the Administrative Measures on the Internet Domain Names promulgated by the MIIT in November 2004. The MIIT is the major regulatory body responsible for the administration of the PRC internet domain names, under supervision of which the China Internet Network Information Center, or CNNIC, is responsible for the daily administration of .cn domain names and Chinese domain names. We have registered Baidu.cn, Baidu.com.cn, hao123.com and certain other domain names with CNNIC.

Regulations on Information Security

The National People’s Congress has enacted legislation that prohibits use of the internet that breaches the public security, disseminates socially destabilizing content or leaks state secrets. Breach of public security

63

##### Table of Contents

includes breach of national security and infringement on legal rights and interests of the state, society or citizens. Socially destabilizing content includes any content that incites defiance or violations of PRC laws or regulations or subversion of the PRC government or its political system, spreads socially disruptive rumors or involves cult activities, superstition, obscenities, pornography, gambling or violence. State secrets are defined broadly to include information concerning PRC national defense, state affairs and other matters as determined by the PRC authorities.

Pursuant to applicable regulations, ICP operators must complete mandatory security filing procedures and regularly update information security and censorship systems for their websites with local public security authorities, and must also report any public dissemination of prohibited content.

In addition, the State Secrecy Bureau has issued provisions authorizing the blocking of access to any website it deems to be leaking state secrets or failing to comply with the relevant legislation regarding the protection of state secrets during online information distribution. Specifically, internet companies in China with bulletin boards, chat rooms or similar services must apply for specific approval prior to operating such services.

Furthermore, the Provisions on Technological Measures for Internet Security Protection, promulgated by the Ministry of Public Security, require all ICP operators to keep records of certain information about its users (including user registration information, log-in and log-out time, IP address, content and time of posts by users) for at least 60 days and submit the above information as required by laws and regulations. The Network Information Protection Decision states that ICP operators must request identity information from users when ICP operators provide information publication services to the users. If ICP operators come across prohibited information, they must immediately cease the transmission of such information, delete the information, keep relevant records, and report to relevant government authorities.

Baidu Netcom, Beijing Perusal, BaiduPay and some other entities in our group are ICP operators, and are therefore subject to the regulations relating to information security. They have taken measures to comply with these regulations. They are registered with the relevant government authority in accordance with the mandatory registration requirement. Baidu Netcom’s policy is to remove links to web pages which to its knowledge contain information that would be in violation of PRC laws or regulations. In addition, we monitor our websites to ensure our compliance with the above-mentioned laws and regulations.

Regulations on Internet Privacy

The PRC Constitution states that PRC law protects the freedom and privacy of communications of citizens and prohibits infringement of these rights. In recent years, PRC government authorities have enacted legislation on internet use to protect personal information from any unauthorized disclosure. The Network Information Protection Decision provides that electronic information that identifies a citizen or involves privacy of any citizen is protected by law and must not be unlawfully collected or provided to others. ICP operators collecting or using personal electronic information of citizens must specify the purposes, manners and scopes of information collection and uses, obtain consent of the relevant citizens, and keep the collected personal information confidential. ICP operators are prohibited from disclosing, tampering with, damaging, selling or illegally providing others with, collected personal information. ICP operators are required to take technical and other measures to prevent the collected personal information from any unauthorized disclosure, damage or loss. The Administrative Measures on Internet Information Services prohibit an ICP operator from insulting or slandering a third party or infringing upon the lawful rights and interests of a third party. Pursuant to the Internet Electronic Messaging Service Administrative Measures, ICP operators that provide electronic messaging services must keep users’ personal information confidential and must not disclose the personal information to any third party without the users’ consent or unless required by law. According to the Provisions on Protection of Personal Information of Telecommunication and Internet Users, telecommunication business operators and ICP operators shall be responsible for the security of the personal information of users they collect or use in the course of their provision of services. Without obtaining the consent from the users, telecommunication business operators and

64

##### Table of Contents

ICP operators may not collect or use the users’ personal information. The personal information collected or used in the course of provision of services by the telecommunication business operators or ICP operators must be kept in strict confidence, and may not be divulged, tampered with or damaged, and may not be sold or illegally provided to others. The ICP operators are required to take certain measures to prevent any divulge, damage, tamper or loss of users’ personal information.

The relevant telecommunications authorities are further authorized to order ICP operators to rectify unauthorized disclosure. ICP operators are subject to legal liability, including warnings, fines, confiscation of illegal gains, revocation of licenses or filings, closing of the relevant websites, administrative punishment, criminal liabilities, or civil liabilities, if they violate relevant provisions on internet privacy. The PRC government, however, has the power and authority to order ICP operators to turn over personal information if an internet user posts any prohibited content or engages in illegal activities on the internet.

Regulations on Foreign Exchange

Foreign Currency Exchange

Pursuant to the Foreign Currency Administration Rules, as amended, and various regulations issued by SAFE and other relevant PRC government authorities, RMB is freely convertible to the extent of current account items, such as trade related receipts and payments, interest and dividends. Capital account items, such as direct equity investments, loans and repatriation of investment, unless expressly exempted by laws and regulations, still require prior approval from SAFE or its provincial branch for conversion of RMB into a foreign currency, such as U.S. dollars, and remittance of the foreign currency outside of the PRC.

Payments for transactions that take place within the PRC must be made in RMB. Foreign currency revenues received by PRC companies may be repatriated into China or retained outside of China in accordance with requirements and terms specified by SAFE.

Dividend Distribution

Wholly foreign-owned enterprises and Sino-foreign equity joint ventures in the PRC may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting standards and regulations. Additionally, these foreign-invested enterprises may not pay dividends unless they set aside at least 10% of their respective accumulated profits after tax each year, if any, to fund certain reserve funds, until such time as the accumulative amount of such fund reaches 50% of the enterprise’s registered capital. In addition, these companies also may allocate a portion of their 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.

Foreign Exchange Registration of Offshore Investment by PRC Residents

Pursuant to SAFE’s Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC Residents to Engage in Financing and Inbound Investment via Overseas Special Purpose Vehicles, or SAFE Circular No. 75, issued in October 2005, and a series of implementation rules and guidance, including the most recent circular relating to operating procedures that came into effect in July 2011, PRC residents, including PRC resident natural persons or PRC companies, must register with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special purpose vehicle, or SPV, for the purposes of overseas equity financing activities. Such PRC residents are also required to amend their registration or filing with the local branches of SAFE for the injection of equity interests or assets of an onshore enterprise into the offshore company, or the overseas funds raised by such offshore company or any other material change involving a change in the capital of the offshore company. PRC residents who are shareholders of SPVs that were established and which have completed their inbound investment before November 1, 2005 were required to register with the local SAFE branch before March 31, 2006. We have notified holders of ordinary shares of our

65

##### Table of Contents

company whom we know are PRC residents to register with the local SAFE branch and update their registrations as required under the SAFE regulations described above. We are aware that Mr. Robin Yanhong Li, our chairman, chief executive officer and principal shareholder, who is a PRC resident, has registered with the relevant local SAFE branch, and is in the process of updating such registration to reflect recent changes as a result of certain acquisitions. We, however, cannot provide any assurances that all of our shareholders who are PRC residents will file all applicable registrations or update previously filed registrations as required by these SAFE regulations. Under SAFE Circular No. 75, failure to comply with the registration procedures set forth above may result in penalties, including restrictions on a PRC subsidiary’s foreign exchange activities and its ability to distribute dividends to the SPV.

In February 2012, SAFE promulgated the Notices on Issues concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly-Listed Company, or the Stock Option Rule, replacing the earlier rules promulgated in March 2007. Under the Stock Option Rule, PRC residents who are granted stock options by an overseas publicly listed company are required, through a PRC agent or PRC subsidiary of such overseas publicly listed company, to register with SAFE and complete certain other procedures. We and our PRC resident employees who have been granted stock options are subject to these regulations. We have designated our PRC subsidiary Baidu Online to handle the registration and other procedures required by the Stock Option Rule. Failure of the option holders to complete their SAFE registrations may subject these PRC employees to fines and legal sanctions and may also limit the ability of the overseas publicly listed company to contribute additional capital into its PRC subsidiary and limit the PRC subsidiary’s ability to distribute dividends.

Regulations on Labor

The Labor Contract Law, which became effective in January 2008, and its implementation rules, impose more restrictions on employers and have been deemed to increase labor costs for employers, compared to the Labor Law, which became effective in January 1995. For example, pursuant to the Labor Contract Law, an employer is obliged to sign labor contract with unlimited term with an employee if the employer continues to hire the employee after the expiration of two consecutive fixed-term labor contracts. The employer has to compensate the employee upon the expiration of a fixed-term labor contract, unless the employee refuses to renew such contract on terms the same as or more favorable to the employee than those contained in the expired contract. The employer also has to indemnify an employee if the employer terminates a labor contract without a cause permitted by law. In addition, under the Regulations on Paid Annual Leave for Employees, which became effective in January 2008, employees who have served more than one year for an employer are entitled to a paid vacation ranging from 5 to 15 days per year, depending on their length of service. Employees who waive such vacation time at the request of employers must be compensated for three times their regular salaries for each waived vacation day.

Regulations on Taxation

Contractual Arrangements with Our Consolidated Affiliated Entities and the Nominee Shareholders

PRC laws and regulations restrict and impose conditions on foreign investment in internet, online advertising, online audio and video services and mobile application distribution businesses. Accordingly, we operate these businesses in China through our consolidated affiliated entities. We have entered into a series of contractual arrangements with our consolidated affiliated entities and the nominee shareholders of our consolidated affiliated entities. These contractual arrangements enable us to:

| • |  | receive substantially all of the economic benefits from our consolidated affiliated entities in consideration for the services provided by our subsidiaries;

| • |  | exercise effective control over our consolidated affiliated entities; and

| • |  | hold an exclusive option to purchase all or part of the equity interests in our consolidated affiliated entities when and to the extent permitted by PRC law.

We do not have any equity interest in our consolidated affiliated entities. However, as a result of contractual arrangements, we have effective control over and are considered the primary beneficiary of these companies, and we have consolidated the financial results of these companies in our consolidated financial statements. If our consolidated affiliated entities or the nominee shareholders fail to perform their respective obligations under the contractual arrangements, we could be limited in our ability to enforce the contractual arrangements that give us effective control over our consolidated affiliated entities. Further, if we are unable to maintain effective control, we would not be able to continue to consolidate the financial results of our consolidated affiliated entities in our financial statements. In 2011, 2012 and 2013, we derived approximately 29%, 29% and 28% of our total revenues, respectively, from our consolidated affiliated entities through contractual arrangements. For a detailed description of the regulatory environment that necessitates the adoption of our corporate structure, see “Item 4.B. Information on the Company—Business Overview—Regulation.” For a detailed description of the risks associated with our corporate structure, see “Item 3.D. Key Information—Risk Factors—Risks Related to Our Corporate Structure.”

Through the design of the aforementioned agreements, the nominee shareholders of these affiliated entities effectively assigned their full voting rights to Baidu Online, which gives Baidu Online the power to direct the activities that most significantly impact the affiliated entities’ economic performance. Baidu Online obtains the ability to approve decisions made by the affiliated entities and the ability to acquire the equity interests in the affiliated entities when permitted by PRC law. Baidu Online is obligated to absorb a majority of the expected losses from the affiliated entities’ activities through providing unlimited financial support to the affiliated entities and is entitled to receive a majority of residual returns from the affiliated entities through the exclusive technology consulting and service fees. As a result of these contractual arrangements, Baidu Online is determined to be the primary beneficiary of these affiliated entities. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between us and these affiliated entities through these contractual arrangements, and we consolidate these affiliated entities through Baidu Online.

We have also entered into contractual arrangements with several other affiliated entities and their respective nominee shareholders through our subsidiaries other than Baidu Online, which results in these subsidiaries being the primary beneficiary of the relevant affiliated entities. As a result of these contractual arrangements, there exists a parent-subsidiary relationship between us and the relevant affiliated entities, and we consolidate these affiliated entities through subsidiaries besides Baidu Online.

D. Property, Plant and Equipment

Baidu Campus, our corporate headquarters, is located in Shangdi, an area designated by the Beijing municipal government as the center of the city’s information technology industry. We also lease some offices in Beijing, Tokyo (Japan), California (USA), Thailand, Brazil, Egypt, Indonesia and many other cities in China, from unrelated third parties.

We host our servers in China at the internet data centers of China Telecom, China Unicom and China Mobile in seven selected cities in China, and we also have content delivery network locations in various cities across China. We expect to use five additional data centers in 2014. We also have a data center of our own in Beijing.

In December 2011, we commenced construction of an office building in Shenzhen, which will serve as our international center in Southern China. We have paid RMB129.5 million (US$21.4 million) for the land use right. Our capital expenditure in connection with the construction of this office building in Shenzhen was RMB109.5 million (US$18.1 million) in 2013. We expect to complete the planned construction at the end of 2016.

In August 2012, we commenced construction of another office building, Baidu Science Park, in Beijing. We have paid in advance RMB444.0 million (US$73.3 million) for the land use right. Our capital expenditures in connection with the construction of Baidu Science Park was RMB173.8 million (US$28.7 million) in 2013. We expect to complete the planned construction in 2015.

In September 2012, we commenced construction of Shanxi Cloud Computing Center, which will serve as our internet data centers in northern China. We have paid RMB71.5 million (US$11.8 million) for the land use right. Our capital expenditure in connection with the construction of Shanxi Cloud computing Center was RMB331.9 million (US$54.8 million) in 2013. We expect to fully complete the planned construction in 2017.

We have paid RMB220.9 million (US$36.5 million) for the right to use three pieces of land in Beijing, where we plan to build our Beijing Cloud Computering Center. We are in the process of planning the construction work, and the completion date is not determinable at this stage.

We currently plan to fund these expenditures with our cash, cash equivalents, short-term investments and anticipated cash flow generated from our operating activities.

A. Operating Results

Overview

Our operations are primarily based in China, where we derive almost all of our revenues. Total revenues in 2013 were RMB31.9 billion (US$5.3 billion), a 43.2% increase over 2012. Operating profit in 2013 was RMB11.2 billion (US$1.8 billion), a slight increase over 2012. Net income attributable to Baidu, Inc. in 2013 was RMB10.5 billion (US$1.7 billion), a slight increase over 2012.

Our total assets as of December 31, 2013 were RMB71.0 billion (US$11.7 billion), of which cash and cash equivalent amounted to RMB9.7 billion (US$1.6 billion). Our total liabilities as of December 31, 2013 were RMB30.3 billion (US$5.0 billion), accounting for 42.7% of total liabilities and equity. As of December 31, 2013, our retained earnings accumulated to RMB34.5 billion (US$5.7 billion).

In July 2011, we completed our acquisition of a majority stake in Qunar and have since then consolidated the financial results of Qunar in our consolidated financial statements. On November 1, 2013, Qunar listed its ADSs, each representing three Class B ordinary shares of Qunar, on the NASDAQ Global Market in connection with its initial public offering. We remain to be the majority shareholder of Qunar after its initial public offering.

In November 2012, we purchased all of the series A and series B preferred shares of Qiyi.com, Inc. held by Providence Equity Partners, which allowed us to control Qiyi.com, Inc., and have since then consolidated the financial results of Qiyi.com, Inc. in our consolidated financial statements. In May 2013, we acquired the online video business of PPStream Inc. and have merged it with iQiyi and have since then consolidated its financial results into our consolidated financial statements.

We are in the process of disposing of all our equity interest in Youa.com, Inc. We own 100% of the ordinary shares in Youa.com, Inc., but do not consolidate its financial results in our financial statements under the U.S. GAAP because of our lack of “control” over the board of directors of Youa.com, Inc. and certain substantive participating rights provided to the preferred shareholders of Youa.com, Inc.

In October 2013, we acquired 100% equity interest of 91 Wireless from NetDragon Websoft Inc. and the other shareholders of 91 Wireless, and have since then consolidated its financial results into our consolidated financial statements.

The major factors affecting our results of operations and financial condition are discussed below.

Revenues

Revenue Generation

We derive almost all of our revenues from online marketing services, which accounted for approximately 99.9%, 99.7% and 99.6% of our total revenues in 2011, 2012 and 2013, respectively.

A majority of our revenues from online marketing services were derived from our P4P services. Our P4P platform is an online marketplace that introduces internet search users to customers who pay us a fee based on click-throughs for priority placement of their links in the search results. We recognize P4P revenues when a user clicks on a customer’s link in the search results, based on the amount that the customer has agreed to pay for each click-through.

We also provide to our customers other performance-based online marketing services and time-based online advertising services. For other performance-based online marketing services, our customers pay us based on performance criteria other than click-throughs, such as the number of telephone calls brought to our customers, the successful booking of air tickets or hotel rooms, the number of users registered with our customers, or the number of minimum click-throughs. For time-based online advertising services, our customers pay us based on the duration of the advertisement placed on our Baidu’s properties and Baidu Union members’ properties.

##### Table of Contents

The most significant factors that directly or indirectly affect our online marketing revenues are:

| • |  | the number of our users and online marketing customers;

| • |  | the number of searches initiated on our websites and our Baidu Union members’ properties;

| • |  | the rate at which users click on paid search results;

| • |  | the competitiveness of bidding for keywords by P4P customers;

| • |  | the total online marketing budgets of our customers; and

| • |  | the total number of sponsored links and advertisements displayed on our websites and the bidding price for each click-through.

Our P4P services revenues have primarily been driven by the increase in the number of page views, the increase in the number of P4P customers, and our success in optimizing the display of sponsored links. We believe that an increase in the number of active P4P customers generally leads to an increase in the number of sponsored links and a higher average price per click-through for selected keywords. Our P4P customer growth has primarily been driven by the adoption of our P4P services by SMEs and, to a lesser extent, large enterprises.

Our online marketing services have historically been driven by the general increase in our customers’ online marketing budgets. We expect the number of our online marketing customers to grow and our customer mix may change. However, we expect our online marketing customer base to remain diverse for the foreseeable future. Any prolonged economic slowdown in China may cause our customers to decrease or delay their online marketing spending, hamper our efforts to grow our customer base, or result in fewer clicks by our users on sponsored links or advertisements displayed on our or Baidu Union members’ properties. Any of these consequences could negatively affect our online marketing revenues.

Our online marketing customers are increasingly seeking marketing solutions with measurable results in order to maximize their ROI. To meet our customers’ needs, we will continue to evaluate the effectiveness of our various products and services and adjust the mix of our service offerings to optimize our customers’ ROI. We expect that we will continue to earn a substantial majority of our revenues from our online marketing services. As a result, we plan to continue focusing most of our resources on expanding our online marketing services.

Revenue Collection

We collect payments for our P4P services both from our customers directly and through our distributors. We require our P4P customers to pay a deposit before using our P4P services and remind them by an automated notice to replenish the accounts after their account balance falls below a designated amount. We deduct the amount due to us from the deposit paid by a customer when a user clicks on the customer’s link in the search results.

We offer payment terms to some of our customers based on their historical marketing placements and credibility. We also offer longer payment terms to certain qualified distributors, consistent with industry practice.

As of December 31, 2013, we had accounts receivable of RMB2.2 billion (US$366.9 million), net of allowance of RMB43.8 million (US$7.2 million), mainly due from customers of other performance-based online marketing services and time-based online advertising services.

Operating Costs and Expenses

Our operating costs and expenses consist of cost of revenues, selling, general and administrative expenses, and research and development expenses. Share-based compensation expenses are allocated among the above three categories of operating costs and expenses, based on the nature of the work of the employees who have received share-based compensation. Our total operating costs and expenses increased significantly from 2011 to 2013 due to the growth of our business.

Traffic Acquisition Costs. Traffic acquisition costs typically represent the portion of our online marketing revenues that we share with our Baidu Union members. We typically pay a Baidu Union member, based on a pre-agreed arrangement, a portion of the online marketing revenues generated from valid click-throughs by users of that member’s properties.

Bandwidth Costs. Bandwidth costs are the fees we pay to telecommunications carriers such as China Telecom and China Unicom for telecommunications services and for hosting our servers at their internet data centers. We expect our bandwidth costs, as variable costs, to increase with the increasing number of racks of servers and the increasing traffic on our websites. Our bandwidth costs could also increase if the telecommunications carriers increase their service charges.

Depreciation of Servers and Other Equipment. We include in our cost of revenues depreciation expenses of servers and other computer hardware that are directly related to our business operations and technical support.

Operational Costs. Operational costs include primarily salary and benefit expenses, intangible assets amortization, travel and other expenses incurred by our operating and technical support personnel. Salary and benefit expenses include wages, bonuses, medical insurance, unemployment insurance, pension benefits, employee housing fund and other welfare benefits.

Content Costs. Content costs consist primarily of the fees we paid for the licensed content from copyright owners or content distributors, and the amortization of the licensed copyrights for video content.

Selling, General and Administrative Expenses

Our selling and marketing expenses primarily consist of promotional and marketing expenses and compensation for our sales and marketing personnel. We expect to incur higher selling and marketing expenses as a result of efforts on our diversified mobile and PC applications distribution and operation, increased compensation for our sales and marketing personnel and our intensified marketing and brand promotion efforts.

Our general and administrative expenses consist primarily of salaries and benefits for our general and administrative personnel and fees and expenses for legal, accounting and other professional services.

Research and Development Expenses

Research and development expenses primarily consist of salaries and benefits for research and development personnel. We expense research and development costs as they are incurred, except for capitalized software development costs that fulfill the capitalization criteria under Accounting Standards Codification, or ASC, subtopic 350-40, Intangibles-Goodwill and Other: Internal-Use Software.

Share-based Compensation Expenses

Baidu, Inc. grants options and restricted shares to our employees as share-based compensation awards. As of December 31, 2013, there was RMB357.3 million (US$59.0 million) unrecognized share-based compensation cost related to options of Baidu, Inc., which is expected to be recognized over a weighted-average vesting period of 2.9 years. As of December 31, 2013, there was RMB652.9 million (US$107.9 million) unrecognized share-based compensation cost related to restricted shares, which is expected to be recognized over a weighted-average vesting period of 2.8 years. To the extent the actual forfeiture rate is different from our original estimate, actual share-based compensation cost related to these awards may be different from our expectation.

Certain of our subsidiaries also have equity incentive plans granting share-based awards. Total share-based compensation expenses recognized and unrecognized were insignificant, both individually or in the aggregate.

Taxation

We are not subject to income or capital gain tax under the current laws of the Cayman Islands and the British Virgin Islands. Under the current laws of Hong Kong, our subsidiaries incorporated in Hong Kong are exempted from income tax on their foreign-derived income. Additionally, none of these jurisdictions impose a withholding tax on dividends.

PRC Enterprise Income Tax

Enterprise Income Tax. The current EIT Law, which became effective on January 1, 2008, imposes a uniform EIT rate of 25% on all PRC resident enterprises, including foreign-invested enterprises and domestic enterprises, unless they qualify for certain exceptions. Pursuant to a Caishui (2008) No. 1 Notice promulgated jointly by the Ministry of Finance and the State Administration of Taxation in February 2008, all preferential EIT treatments granted prior to January 1, 2008 are eliminated, except for those specified under the EIT Law and certain other tax regulations.

An enterprise may benefit from a preferential tax rate of 15% under the EIT Law if it qualifies as a “High and New Technology Enterprise strongly supported by the state.” Pursuant to the Administrative Measures on the Recognition of High and New Technology Enterprises, the provincial counterparts of the Ministry of Science and Technology, the Ministry of Finance and the State Administration of Taxation shall jointly determine whether an enterprise is qualified as a “High and New Technology Enterprise” under the EIT Law. In making such determination, these government agencies shall consider, among other factors, ownership of core technology, whether the products or services fall within the scope of high and new technology strongly supported by the state as specified in the measures, the ratios of technical personnel and research and development personnel to total personnel, the ratio of research and development expenditures to annual sales revenues, the ratio of revenues attributed to high and new technology products or services to total revenues, and other measures set forth in relevant guidance. All enterprises that had been granted the “High and New Technology Enterprise” status before the effectiveness of the EIT Law are required to be re-examined in accordance with the measures mentioned above before they can be entitled to the preferential tax rate. A “High and New Technology Enterprise” certificate is effective for a period of three years and could be renewed for another three years. After that, an entity needs to re-apply for the “High and New Technology Enterprise” status in order to be able to enjoy the preferential tax rate of 15%. A number of PRC subsidiaries and consolidated affiliated entities, such as Baidu Online and Baidu Netcom, obtained the “High and New Technology Enterprise” certificate. The “High and New Technology Enterprise” certificates of these entities will expire on January 1, 2014, 2015 or 2016.

78

##### Table of Contents

An enterprise may benefit from a preferential tax rate of 10% under the EIT law if it qualifies as a “Key Software Enterprise” designated jointly by the National Development and Reform Commission, MIIT, Ministry of Commerce and State Administration of Taxation. A “Key Software Enterprise” certificate is effective for a period of two years. After that, an entity needs to re-apply for the “Key Software Enterprise” status in order to be able to enjoy the preferential tax rate of 10%. Baidu Online obtained the “Key Software Enterprise” certificate and the certificate and the related tax holiday will expire on January 1, 2015.

If any entity fails to maintain the “High and New Technology Enterprise” or “Key Software Enterprise” qualification under the EIT Law, their tax rates will increase, which could have a material and adverse effect on our results of operations and financial position. Historically, all of the above mentioned PRC subsidiaries and consolidated affiliated entities successfully re-applied for the certificates when the prior ones expired.

If our PRC subsidiaries or consolidated affiliated entities that have enjoyed preferential tax treatment no longer qualify for the treatment, we will consider available options under applicable law that would enable us to qualify for alternative preferential tax treatment. To the extent we are unable to offset the impact of the expiration of existing preferential tax treatment with new tax exemptions, tax incentives or other tax benefits, the expiration of existing preferential tax treatment may cause our effective tax rate to increase. The amount of income tax payable by our PRC subsidiaries and consolidated affiliated entities in the future will depend on various factors, including, among other things, the results of operations and taxable income of, and the statutory tax rate applicable to, each of the entities. Our effective tax rate depends partially on the extent of the relative contribution of each of our subsidiaries and consolidated affiliated entities to our consolidated taxable income. In 2011, 2012 and 2013, our consolidated effective tax rate was 15.22%, 13.16% and 15.01%, respectively.

Withholding Tax

Under the EIT Law and its implementation rules, dividends, interests, rent or royalties payable by a foreign-invested enterprise, such as our PRC subsidiaries, to any of its non-resident enterprise investors, and proceeds from any such non-resident enterprise investor’s disposition of assets (after deducting the net value of such assets) shall be subject to a 10% EIT, namely withholding tax, unless the non-resident enterprise investor’s jurisdiction of incorporation has a tax treaty or arrangement with China that provides for a reduced withholding tax rate or an exemption from withholding tax. The Caishui (2008) No. 1 Notice clarifies that undistributed profits earned by foreign-invested enterprises prior to January 1, 2008 will be exempted from any withholding tax.

The British Virgin Islands, where Baidu Holdings Limited, the sole shareholder of certain of our PRC subsidiaries such as Baidu Online, was incorporated, does not have such a tax treaty with China.

Hong Kong, where Baidu (Hong Kong) Limited, our wholly owned subsidiary and the sole shareholder of certain of our PRC subsidiaries such as Baidu Times and Baidu China, was incorporated, has a tax arrangement with China that provides for a lower withholding tax rate of 5% on dividends subject to certain conditions and requirements, such as the requirement that the Hong Kong resident enterprise own at least 25% of the PRC enterprise distributing the dividend at all times within the 12-month period immediately preceding the distribution of dividends and be a “beneficial owner” of the dividends. However, pursuant to a SAT Circular 81 issued by the State Administration of Taxation in February 2009, if the relevant PRC tax authorities determine, in their discretion, that a company benefits from the reduced withholding tax rate on dividends due to a structure or arrangement designed for the primary purpose of obtaining favorable tax treatment, the PRC tax authorities may adjust the preferential tax treatment. Moreover, pursuant to a SAT Circular 601 issued by the State Administration of Taxation in October 2009, a resident of a contracting state will not qualify for the benefits under the tax treaties or arrangements, if it is not the “beneficial owner” with respect to dividend, interest and royalty income. According to SAT Circular 601, a “beneficial owner” shall have ownership and right to dispose of the income or the rights and properties giving rise to the income, and generally engages in substantive business activities. An agent or conduit company will not be regarded as a “beneficial owner” and, therefore, will

79

##### Table of Contents

not qualify for treaty benefits. A conduit company normally refers to a company that is set up primarily for the purpose of evading or reducing taxes or transferring or accumulating profits.

If our PRC subsidiaries declare and distribute profits earned after January 1, 2008 to us in the future, the dividend payments will be subject to withholding tax, which will increase our tax liability and reduce the amount of cash available to our company.

Tax Residence

Under the EIT Law and its implementation rules, an enterprise established outside of the PRC with “de facto management body” within the PRC is considered a resident enterprise and will be subject to the EIT at the rate of 25% on its worldwide income. The term “de facto management body” refers to “the establishment that exercises substantial and overall management and control over the production, business, personnel, accounts and properties of an enterprise.”

Pursuant to SAT Circular 82 issued by the State Administration of Taxation in April 2009, an overseas registered enterprise controlled by a PRC company or a PRC company group will be classified as a “resident enterprise” with its “de facto management body” located within China if the following requirements are satisfied: (i) the senior management and core management departments in charge of its daily operations are mainly located in the PRC; (ii) its financial and human resources decisions are subject to determination or approval by persons or bodies located in the PRC; (iii) its major assets, accounting books, company seals, and minutes and files of its board and shareholders’ meetings are located or kept in the PRC; and (iv) no less than half of the enterprise’s directors or senior management with voting rights reside in the PRC. In July 2011, the State Administration of Taxation issued additional rules to provide more guidance on the implementation of SAT Circular 82. Although the SAT Circular 82 and the additional guidance only apply to overseas registered enterprises controlled by PRC enterprises and not those controlled by PRC individuals or foreigners, the determining criteria set forth in the circular may reflect the State Administration of Taxation’s general position on how the “de facto management body” test should be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises, individuals or foreigners.

If we are deemed a PRC resident enterprise, we may be subject to the EIT at the rate of 25% on our global income, except that the dividends we receive from our PRC subsidiaries may be exempt from the EIT to the extent such dividends are deemed “dividends among qualified resident enterprises.” If we are considered a resident enterprise and earn income other than dividends from our PRC subsidiaries, a 25% EIT on our global income could significantly increase our tax burden and materially and adversely affect our cash flow and profitability.

PRC Business Tax and VAT

In November 2011, the PRC Ministry of Finance and the State Administration of Taxation jointly issued two circulars setting out the details of the pilot VAT reform program, which change the charge of sales tax from business tax to VAT for certain pilot industries. The pilot VAT reform program initially applied only to the pilot industries in Shanghai, and was expanded to eight additional regions, including, among others, Beijing and Guangdong province, in 2012. In August 2013, the program was further expanded nationwide.

With respect to all of our PRC entities for the period immediately prior to the implementation of the pilot VAT reform program, revenues from our P4P services, online advertising services and other services are subject to a 5% PRC business tax. Revenues from our online advertising services are subject to an additional 3% cultural business construction fee.

Our entities located in Shanghai, Beijing and Guangdong Province fall within the scope of the pilot program and have been recognized as the VAT general taxpayers since January 1, 2012, September 1, 2012 and November 1, 2012, respectively, the effective time of the pilot program in each of the regions. Our entities

located outside of Shanghai, Beijing and Guangdong Province have been subject to VAT since August 1, 2013. From the applicable effective time onwards, these entities are required to pay VAT instead of business tax for P4P services, online advertising services and other services that are deemed by the relevant tax authorities to be within the pilot industries at a rate of 6%. In addition, cultural business construction fee is imposed at the rate of 3% on revenues derived from our online advertising services.

PRC Urban Maintenance and Construction Tax and Education Surcharge

Any entity, foreign-invested or purely domestic, or individual that is subject to consumption tax, VAT and business tax is also required to pay PRC urban maintenance and construction tax. The rates of urban maintenance and construction tax are 7%, 5% or 1% of the amount of consumption tax, VAT and business tax actually paid depending on where the taxpayer is located. All entities and individuals who pay consumption tax, VAT and business tax are also required to pay education surcharge at a rate of 3%, and local education surcharges at a rate of 2%, of the amount of VAT, business tax and consumption tax actually paid.

Year Ended December 31, 2013 Compared to Year Ended December 31, 2012

Revenues. Our total revenues increased by 43.2% from RMB22.3 billion in 2012 to RMB31.9 billion (US$5.3 billion) in 2013. This increase was due to a substantial increase in our revenues from online marketing services. Our online marketing revenues increased by 43.0% from RMB22.2 billion in 2012 to RMB31.8 billion (US$5.3 billion) in 2013. This increase was mainly attributable to the increase in the number of our active online marketing customers from approximately 596,000 in 2012 to 753,000 in 2013, and the increase in the average revenue per customer from approximately RMB37,300 in 2012 to approximately RMB42,200 (US$6,971) in

82

##### Table of Contents

2013. The increase in our active online marketing customers was mainly due to our effective distribution network and direct sales. The increase in the average revenue per customer was primarily attributable to the increase in the number of paid clicks and the higher price per click as more customers participated in our P4P auction platform. The number of active online marketing customers and average revenue per customer exclude our group-buying related businesses, consistent with previous reporting. The number of paid clicks increased by approximately 32.7% from 2012 to 2013.

Operating Costs and Expenses. Our total operating costs and expenses increased by 84.4% from RMB11.3 billion in 2012 to RMB20.8 billion (US$3.4 billion) in 2013. This increase was primarily due to the expansion of our business.

| • |  | Cost of Revenues. Our cost of revenues increased by 77.9% from RMB6.4 billion in 2012 to RMB11.5 billion (US$1.9 billion) in 2013. This increase was primarily due to the following factors:

| • |  | Traffic Acquisition Costs. Our traffic acquisition costs increased by 91.9% from RMB1.9 billion in 2012 to RMB3.7 billion (US$611.9 million) in 2013. Traffic acquisition costs represent 11.6% of total revenues in 2013, compared to 8.7% in 2012. The increase in traffic acquisition costs as a percentage of total revenues reflects an increased revenue contribution from our Baidu Union members, primarily the increased contribution of contextual ads and hao123 promotions from our Baidu Union members.

| • |  | Bandwidth Costs and Depreciation Expenses. Our bandwidth costs increased by 81.3% from RMB1.1 billion in 2012 to RMB1.9 billion (US$320.2 million) in 2013. Our depreciation expenses of servers and other equipment increased by 38.4% from RMB1.1 billion in 2012 to RMB1.5 billion (US$242.8 million) in 2013. The absolute increases in these costs were mainly due to an increase in network infrastructure capacity and iQiyi.

| • |  | Sales Tax and Surcharges. Our sales tax and surcharges increased by 48.2% from RMB1.6 billion in 2012 to RMB2.3 billion (US$384.8 million) in 2013, primarily as a result of the increase in our online marketing revenues.

| • |  | Operational Costs. Our operational costs increased by 99.4% from RMB589.6 million in 2012 to RMB1.2 billion (US$194.2 million) in 2013, primarily due to amortization of acquired intangible assets related to the acquired companies and higher personnel related expenses.

| • |  | Content Costs. Our content costs increased by 286.0% from RMB215.1 million in 2012 to RMB830.4 million (US$137.2 million) in 2013, primarily due to the increase of video content cost of iQiyi, which has been consolidated into our financial statements since November 2012.

| • |  | Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased by 106.8% from RMB2.5 billion in 2012 to RMB5.2 billion (US$854.6 million) in 2013. This increase was primarily due to the following factors:

| • |  | total salaries and benefits and staff-related expenses increased by 57.0% from RMB1.2 billion in 2012 to RMB1.9 billion (US$313.1 million) in 2013, primarily due to the increased headcount to support our expanded online marketing services and the increase of sales commission;

| • |  | total office operating expenses increased by 51.2% from RMB186.5 million in 2012 to RMB281.9 million (US$46.6 million) in 2013, primarily as a result of increase and expansion of our offices;

| • |  | total traveling, communication and business development expenses increased by 66.9% from RMB101.3 million in 2012 to RMB169.0 million (US$27.9 million) in 2013, primarily due to the increased headcount and activities to support our expanded online marketing services;

The other income, net, including exchange gains or losses in 2012 was primarily attributable to gains arising from re-measurement of some existing equity method investments immediately before the acquisition of these investees in 2012, whereas we had no such transaction in 2013.

Loss from equity method investments: Our loss from equity method investments decreased from RMB294.2 million in 2012 to RMB5.8 million (US$1.0 million) in 2013. The loss in 2012 primarily related to the recognized accumulated losses of Youa.com Inc. and Qiyi.com, Inc., whereas such loss from in 2013 was not significant as Qiyi.com Inc. has been consolidated into our financial statements since November 2012 and the carrying amount of long-term investment in Youa.com Inc. has been reduced to zero.

Taxation. Our income tax expenses increased by 16.2% from RMB1.6 billion in 2012 to RMB1.8 billion (US$302.1 million) in 2013, primarily due to the increase in profit before tax in 2013.

Net income attributable to Baidu, Inc. As a result of the foregoing, net income attributable to Baidu, Inc. increased slightly from RMB10.46 billion in 2012 to RMB10.52 billion (US$1.7 billion) in 2013.

Net income attributable to Baidu, Inc. As a result of the foregoing, net income attributable to Baidu, Inc. increased by 57.5% from RMB6.6 billion in 2011 to RMB10.5 billion in 2012.

Inflation

Inflation in China has not materially impacted our results of operations. According to the National Bureau of Statistics of China, the annual average percent changes in the consumer price index in China for 2011, 2012 and 2013 were increases of 5.4%, 2.6% and 2.6%, respectively. The year-over-year percent changes in the consumer price index for January 2012, 2013 and 2014 were increases of 4.5%, 2.0% and 2.5%, respectively. Although we have not been materially affected by inflation in the past, we can provide no assurance that we will not be affected in the future by higher rates of inflation in China. For example, certain operating costs and expenses, such as employee compensation and office operating expenses may increase as a result of higher inflation. Additionally, because a substantial portion of our assets consists of cash and cash equivalents and short-term investments, high inflation could significantly reduce the value and purchasing power of these assets. We are not able to hedge our exposure to higher inflation in China.

Foreign Currency

The average exchange rate between U.S. dollar and RMB has declined from RMB8.2264 per U.S. dollar in July 2005 to RMB6.0738 per U.S. dollar in December 2013. As of December 31, 2013, we recorded RMB163.3 million (US$27.0 million) of net foreign currency translation gain in accumulated other comprehensive income as a component of shareholders’ equity. We have not hedged exposures to exchange fluctuations using any hedging instruments. See also “Item 3.D. Key Information—Risk Factors—Risks Related to Doing Business in China—Fluctuation in the value of the RMB may have a material and adverse effect on your investment.” and “Item 11.Quantitative and Qualitative Disclosures about Market Risk—Foreign Exchange Risk.”

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect the reported amounts of our assets and liabilities and the disclosure of our contingent assets and liabilities at the end of each fiscal period and the reported amounts of revenues and expenses during each fiscal period. We continually evaluate these judgments and estimates based on our own historical experience, knowledge and assessment of current business and other conditions, our expectations regarding the future based on available information and assumptions that we believe to be reasonable, which together form our basis for making judgments about matters that are not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, our actual results could differ from those estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

The selection of critical accounting policies, the judgments and other uncertainties affecting application of those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should be considered when reviewing our financial statements. For further information on our significant accounting policies, see Note 2 to our consolidated financial statements. We believe the following accounting policies involve the most significant judgments and estimates used in the preparation of our financial statements.

Consolidation of Affiliated Entities

In order to comply with PRC laws and regulations limiting foreign ownership of or imposing conditions on internet, online advertising, online audio and video services and mobile application distribution businesses, we operate our websites and conduct our online advertising, online audio and video services and mobile application

distribution businesses through our affiliated entities in China by means of contractual arrangements. We have entered into certain exclusive agreements with the affiliated entities through our subsidiaries, which obligate them to absorb a majority of the risk of loss and receive a majority of the residual returns from the affiliated entities’ activities. In addition, we have entered into certain agreements with the affiliated entities and the nominee shareholders of affiliated entities through our subsidiaries, which enable us to direct the activities that most significantly affect the economic performance of the affiliated entities. Based on these contractual arrangements, we consolidate the affiliated entities as required by SEC Regulation SX-3A-02 and ASC topic 810, Consolidation, because we hold all the variable interests of the affiliated entities through the subsidiaries, which are the primary beneficiaries of the affiliated entities. We will reconsider the initial determination of whether a legal entity is a consolidated affiliated entity upon certain events listed in ASC 810-10-35-4 occurred. We will also continuously reconsider whether we are the primary beneficiaries of our affiliated entities as facts and circumstances change. See “Item 3.D. Risk Factors—Risks Related to Our Corporate Structure.”

Revenue Recognition

We recognize revenues based on the following principles:

(1) Click-through based online marketing services

Our auction-based P4P platform enables a customer to place its website link and related description on our search result list on the website which could be accessed through personal computers or mobile devices. The customers make bids on keywords based on how much they are willing to pay for each click to their listings in the search results listed on our website and the relevance between the keywords and the customer’s businesses. Internet users’ search of the keyword will trigger the display of the listings. The ranking of the customer’s listing depends on both the bidding price and the listing’s relevance to the keyword searched. Customer pays us only when a user clicks on one of its website links. Other than the auction-based P4P platform, we have certain vertical platforms from which we generate revenue through pre-determined prices per click. Revenue is recognized when a user clicks on one of the customer-sponsored website links, as there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection is reasonably assured, as prescribed by ASC topic 605, or ASC 605, Revenue Recognition.

For certain customers engaged through direct sales, we may provide certain value-added consultative support services to help its customers to better utilize its online marketing system. Fees for such services are recognized as revenue on a pro-rata basis over the contracted service period.

(2) Other performance-based online marketing services

To the extent we provide online marketing services based on performance criteria other than click-throughs, such as the number of telephone calls brought to our customers, the number of users registered with our customers, the number of minimum click-throughs, the number of successful reservation of hotels or issuance of air tickets, the number of downloads (and user registrations) of mobile applications, the number of incremental end users and the total incremental revenue generated, revenue is recognized when the specified performance criteria are met together with satisfaction of other applicable revenue recognition criteria as prescribed by ASC 605.

(3) Time-based online advertising services

For time-based online advertising services such as text links, banners, icons or other forms of graphical advertisements on the websites or mobile applications, we recognize revenue, in accordance with ASC 605, on a pro-rata basis over the contractual term commencing on the date the customer’s advertisement is displayed on a specified web page or mobile applications. For certain time-based contractual agreements, we may also provide certain performance guarantees, in which cases revenue is recognized at the later of the completion of the time commitment or performance guarantee.

We operate an online game platform, on which registered users can access games provided by third-party game developers. We also operates mobile platforms on which users can access smartphone related products such as themes, wallpapers and e-books developed and owned by third-party content providers. The rights and obligations of each party to the arrangement indicate that we are acting as an agent whereas the game developer or the content provider is the principal as a result of being the primary obligor in the arrangement in accordance with ASC subtopic 605-45 (“ASC 605-45”), Revenue Recognition: Principal Agent Consideration.

We recognize the shared revenue from these online promotional services, on a net basis, based on the ratios pre-determined with the game developers or content providers when all the revenue recognition criteria set forth in ASC 605 are met, which is generally when the user purchases virtual currencies issued by the game developers or purchases contents developed by the content providers.

(5) Online marketing services involving Baidu Union

Baidu Union is the program through which we expand distribution of our customers’ sponsored links or advertisements by leveraging traffic of the Baidu Union members’ internet properties. We make payments to Baidu Union members for acquisition of traffic. We recognize gross revenue for the amount of fees we receive from our customers. Payments made to Baidu Union members are included in cost of revenues as traffic acquisition costs.

(6) Group buying services

We generate revenue from group buying services as a marketing agent by offering goods and services provided by third-party merchant partners at a discount through the website or mobile application that connects merchants to consumers. We present revenue on a net basis, representing the amount billed to registered users less the amount paid to merchants, in accordance with ASC 605-45. We act as an agent rather than as the principal in the delivery of the products or services as it does not assume the risks and rewards of ownership of products nor is it responsible for the actual fulfillment of services. Both of these are the responsibilities of the merchants. We recognize revenue when all of the criteria prescribed in ASC 605 are met, which is generally when the merchants provide the services or when the products are delivered to the customers, or upon the end of redemption period. Since our paying users have the ability to request for full refund before redemption for the products or services offered by the merchants, the underlying sale from which we earn the related commission revenue as an agent is not culminated until our paying users actually redeem.

(7) Barter transactions

We engage in barter transactions from time to time and in such situations follow the guidance set forth in ASC topic 845, Nonmonetary Transactions. While nonmonetary transactions are generally recorded at fair value, if such value is not determinable within reasonable limits, the transaction is recognized based on the carrying value of the products or services provided. We also engage in certain advertising barter transactions and follow the guidance set forth in ASC subtopic 605-20, or ASC 605-20, Revenue Recognition: Services. The advertising barter transactions generally are recorded at fair value. If the fair value of the advertising surrendered in the barter transaction is not determinable within required limits, the barter transaction is recorded based on the carrying amount of the advertising surrendered, which is likely to be zero. The amount of revenues recognized for barter transactions was insignificant for each of the periods presented.

In certain instances, we are granted equity instruments in exchange for services and account for such transactions in accordance with ASC 845, Nonmonetary Transactions. With respect to the measurement date, in accordance with ASC subtopic 505-50, or ASC 505-50, Equity: Equity-based Payments to Non-Employees, we measure the fair value of those equity instruments for revenue recognition purposes as of the earlier of either of the following dates:

| • |  | The date the parties come to a mutual understanding of the terms of the equity-based compensation arrangement and a commitment for performance by us to earn the equity instruments is reached;

88

##### Table of Contents

| • |  | The date when our performance necessary to earn the equity instruments is completed.

If, as of the measurement date, the fair value of the equity instruments received is not determinable within reasonable limits, the transaction is recognized based on the fair value of the services provided. If the fair value of both the equity instruments received and the services provided cannot be determined, no revenue is recognized for the services provided and the equity instrument received is recorded at zero carrying value. The amount of revenues recognized for such transactions was insignificant for each of the years presented.

(8) Other revenue recognition related policies

In accordance with ASC subtopic 605-25, or ASC 605-25, Multiple-Deliverable Revenue Arrangements, for deliverables in multiple-element arrangements, the total consideration of the arrangements is allocated based on their relative selling price, with the selling price of each deliverable determined using vendor-specific objective evidence of selling price, or VSOE, third-party evidence or TPE of selling price, or management’s best estimate of the selling price, or BESP. We consider all reasonably available information in determining the BESP, including both market and entity-specific factors.

We deliver some of our online marketing services to end customers through engaging third party distributors. In this context, we may provide cash incentives to distributors. The cash incentives are accounted for as reduction of revenue in accordance with ASC subtopic 605-50, Revenue Recognition: Customer Payments and Incentives.

We provide sales incentives to customers to entitle customers to receive reductions in the price of the online marketing services by meeting certain cumulative consumption requirements. We account for these award credits granted to members in conjunction with a current sale of products or services as a multiple-element arrangement by analogizing to ASC 605-25. The consideration allocated to the award credits, as deferred revenue, is based on an assumption that the customer will purchase the minimum amount of future service necessary to obtain the maximum award credits available. The deferred revenue is recognized as revenue proportionately as the future services are delivered to the customer or when the award credits expire.

Cash received in advance from customers is recorded as customer advances and deposits. The unused cash balances remaining in customers’ accounts are included as liabilities of us. Deferred revenue is recorded when services are provided before the other revenue recognition criteria set forth in ASC 605 are fulfilled.

Share-based Compensation

We account for share-based compensation in accordance with ASC topic 718, or ASC 718, Compensation-Stock Compensation: Overall. We have elected to recognize share-based compensation using the straight-line method for all share-based awards issued with no performance conditions. For awards with performance conditions, compensation cost is recognized on an accelerated basis if it is probable that the performance condition will be achieved.

Forfeitures have been estimated based on historical experience and are periodically reviewed. Cancellation of an award accompanied by the concurrent grant of a replacement award is accounted for as a modification of the terms of the cancelled award, or the modification awards. The compensation costs associated with the modification awards are recognized if either the original vesting condition or the new vesting condition has been achieved. Such compensation costs will not be less than the grant-date fair value of the original award. The incremental compensation cost is measured as the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation date. Therefore, in relation to the modification awards, we recognize share-based compensation over the vesting periods of the new options, which comprises, (i) the amortization of the incremental portion of share-based compensation over the remaining vesting term, and (ii) any unrecognized compensation cost of original award, using either the original term or the new term, whichever results in higher expenses for each reporting period.

89

##### Table of Contents

We account for share awards issued to non-employees in accordance with the provisions of ASC 505-50. We use the Black-Scholes-Merton option pricing model method to measure the value of options granted to non-employees at each vesting date to determine the appropriate charge to share-based compensation. ASC 718 also requires share-based compensation to be presented in the same manner as cash compensation rather than as a separate line item.

Income Taxes

We recognize income taxes under the liability method. Deferred income taxes are recognized for differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the years in which the differences are expected to reverse. We record a valuation allowance against the amount of deferred tax assets that we determine is not more likely than not to be realized. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date. For reconciliation of tax computed by applying the respective statutory income tax rate to pre-tax income, please see “Income taxes” under Note 12 to our audited consolidated financial statements.

We comply with the provisions of ASC topic 740, or ASC 740, Income Taxes, in accounting for uncertainty in income taxes. ASC 740 clarified the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. We have elected to classify interest and penalties related to an uncertain tax position (if and when required) as part of income tax expense in the consolidated statements of comprehensive income. As of and for the years ended December 31, 2011, 2012 and 2013, the amounts of unrecognized tax benefits as well as interest and penalties associated with uncertainty in income taxes were insignificant.

Allowance for Doubtful Accounts

Accounts receivable are recognized and carried at original invoiced amount less an allowance for any potential uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer probable. Bad debts are written off as incurred. We generally do not require collateral from our customers.

We maintain allowances for doubtful accounts for estimated losses resulting from the failure of customers to make payments on time. We review the accounts receivable on a periodic basis and make general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, we consider many factors, including the age of the balance, the customer’s payment history, its current credit-worthiness and current economic trends.

Impairment of Long-Lived Assets Other Than Goodwill

We evaluate long-lived assets, such as fixed assets and purchased or internally developed intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with ASC topic 360, or ASC 360, Property, Plant and Equipment. When such events occur, we assess the recoverability of the assets group based on the undiscounted future cash flow the assets group is expected to generate and recognize an impairment loss when estimated undiscounted future cash flow expected to result from the use of the assets group plus net proceeds expected from disposition of the assets group, if any, is less than the carrying value of the assets group. If we identify an impairment, we reduce the carrying amount of the assets group to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values. We use estimates and judgments in our impairment tests and if different estimates or judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet. The impairment charges of long-lived assets are RMB8.0 million, nil and RMB6.7 million (US$1.1 million) for 2011, 2012 and 2013, respectively.

Impairment of Goodwill

We assess goodwill for impairment in accordance with ASC subtopic 350-20, or ASC 350-20, Intangibles—Goodwill and Other: Goodwill, which requires that goodwill be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20.

Prior to 2011, we had one reporting unit because no discrete financial information was available below the consolidation level. Subsequent to the acquisitions in 2011 and thereafter, there were segment managers who regularly review the operating results of certain acquired entities and the rest of our group, which constituted two, three and three separate reporting units as of December 31, 2011 and 2012 and 2013, respectively.

Goodwill was tested for impairment in the annual impairment tests on December 31 in each year using the two-step process required by ASC 350-20. First, we compared the carrying amount of the reporting unit compared to the fair value of the reporting unit based on either quoted market prices of the ordinary shares or estimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and we are not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss. In accordance with ASU No. 2011-08, or ASU 2011-08, Testing Goodwill for Impairment, we have the option to first assess qualitative factors to determine whether it is necessary to perform the two-step test. If we believe, as a result of the qualitative assessment, that it is more-like-than-not that the fair value of the reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required.

In 2013, we elected to assess goodwill for impairment test for goodwill at the two reporting units, representing acquired entities, using the two-step process. The fair value of these two reporting units exceeded their respective carrying amount, and therefore goodwill related to the two reporting units were not impaired and we were not required to perform further testing. We performed a qualitative assessment for the remaining reporting unit. Based on the requirements of ASU 2011-08, we evaluated all relevant factors, weighed all factors in their totality and concluded that it was not more-likely-than-not the fair value was less than the carrying amount of the third reporting unit, and further impairment testing on goodwill was unnecessary as of December 31, 2013.

The impairment charges of goodwill are RMB113.0 million, nil and nil for 2011, 2012 and 2013, respectively.

Impairment of Long-term Investments

Our long-term investments mainly consist of cost method investments and equity method investments in privately held companies.

We periodically review our cost method investments and equity method investments for impairment. If we conclude that any of such investments is impaired, we will assess whether such impairment is other-than-temporary. Factors we consider to make such determination include the performance and financial position of the investee as well as other evidence of market value. Such evaluation includes but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of investment.

91

##### Table of Contents

The fair value determination, particularly for investments in privately-held companies, requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and the determination of whether any identified impairment is other-than-temporary. If impairment is considered other-than-temporary, we will write down the asset to its fair value and take the corresponding charge to the consolidated financial statements. The impairment charges of long-term investments are RMB47.9 million, RMB169.2 million and RMB17.5 million (US$2.9 million) for 2011, 2012 and 2013, respectively.

Business Combination

We account for business combinations using the purchase method of accounting in accordance with ASC 805: Business Combinations. The purchase method accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities we acquired, based on their estimated fair values. The consideration transferred of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings.

In a business combination achieved in stages, we remeasured our previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the re-measurement gain or loss, if any, was recognized in earnings.

The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. We determine discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period.

B. Liquidity and Capital Resources

As of December 31, 2013, our principal sources of liquidity was RMB38.4 billion (US$6.3 billion) of cash, cash equivalents and short-term investments. Our cash and cash equivalents consist of cash on hand and investments in interest bearing demand deposit accounts, time deposits, money market funds and other liquid investments which have original maturities of three months or less. The short-term investments primarily consist of fixed-rate and adjustable-rate debt investments with original maturity of less than one year. We believe that our current cash, cash equivalents, short-term investments and anticipated cash flow from operations will be sufficient to meet our anticipated cash needs, including our cash needs for working capital and capital expenditures, for at least the next 12 months. We may, however, require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If our existing cash is insufficient to meet our requirements, we may seek to sell additional equity securities, debt securities or borrow from banks.

Furthermore, cash transfers from our PRC subsidiaries to their parent companies outside of China are subject to PRC government control of currency conversion. Shortages in the availability of foreign currency may

92

##### Table of Contents

restrict the ability of our PRC subsidiaries and consolidated affiliated entities to remit sufficient foreign currency to pay dividends or other payments to us, or otherwise satisfy their foreign currency denominated obligations. See “Risk Factors—Risks Related to Doing Business in China—Governmental control of currency conversion may affect the value of your investment.” As of December 31, 2013, our PRC subsidiaries and consolidated affiliated entities held RMB33.6 billion (US$5.5 billion) of cash, cash equivalents and short-term investments, RMB730.6 million (US$120.7 million) of which were in the form of foreign currencies.

In July 2011, we entered into a two-year unsecured loan arrangement with Goldman Sachs Lending Partners LLC of US$350.0 million, at an annual interest rate of 1.3%. The loan was used to acquire Qunar’s ordinary shares. We repaid the loan and all accrued interest in July 2013 upon maturity, and there was no outstanding balance as of December 31, 2013.

In September 2012, we entered into a loan agreement with Australia and New Zealand Banking Group Limited (Hong Kong Branch), whereby we committed to borrow an unsecured loan of AU$105.0 million (US$108.0 million) for general working capital purposes. We drew down AU$55.0 million (settled by US$56.8 million) in October 2012 under the loan commitment, with a term of two years and a fixed annual interest rate of 2.75%. The remaining commitment of AU$50.0 million was cancelled by both parties. As of December 31, 2013, we had an outstanding balance of AU$55.0 million (US$56.8 million), which will be due in October 2014.

In July 2013, we entered into a loan agreement with Sumitomo Mitsui Banking Corporation, whereby we committed to borrow an unsecured loan of US$150.0 million for general working capital purposes. We drew down US$150.0 million in July 2013 under the loan commitment, with a term of two years and a fixed annual interest rate of 1.17%. As of December 31, 2013, we had an outstanding balance of US$150.0 million, which will be due in July 2015.

In August 2013, we entered into a loan agreement with Australia and New Zealand Banking Group Limited (Hong Kong Branch), whereby we committed to borrow an unsecured loan of AU$235.0 million (US$200.0 million) for general working capital purposes. We drew down AU$235.0 million (US$200.0 million) in August 2013 under the loan commitment, with a term of two years and a fixed annual interest rate of 1.65%. As of December 31, 2013, we had an outstanding balance of AU$235.0 million (US$200.0 million), which will be due in August 2015.

In November 2012, we issued an aggregate of US$1.5 billion senior unsecured notes in two equal tranches, due in 2017 and 2022, with stated annual interest rates of 2.25% and 3.50%, respectively. The net proceeds from the sale of the notes were used for general corporate purposes. As of December 31, 2013, the total carrying value and estimated fair value of these notes were US$1.5 billion and US$1.4 billion. The estimated fair value was based on quoted prices for our publicly-traded debt as of December 31, 2013. We are not subject to any financial covenants or other significant restrictions under the notes. During 2013, we paid an aggregate of US$43.1 million in interest payments related to these notes.

In August 2013, we issued an aggregate of US$1.0 billion senior unsecured notes due in 2018, with stated annual interest rate of 3.25%. The net proceeds from the sale of the notes were used for general corporate purposes, including merger and acquisition activities. As of December 31, 2013, the total carrying value and estimated fair value of these notes were US$1.0 billion and US$1.0 billion, respectively. The estimated fair value was based on quoted prices for our publicly-traded debt as of December 31, 2013. We are not subject to any financial covenants or other significant restrictions under the notes. No interest were due in year 2013 related to these notes.

We may use the net proceeds from our issuance and sale of the notes to fund the operations of our PRC subsidiaries by making additional capital contribution to our existing PRC subsidiaries, injecting capital to

93

##### Table of Contents

establish new PRC subsidiaries and/or providing loans to our PRC subsidiaries. Such transfer of funds from Baidu, Inc. or any of our offshore subsidiaries to our PRC subsidiaries is subject to the PRC regulatory restrictions and procedures: (i) capital increase of the existing PRC subsidiaries and establishment of new PRC subsidiaries must be approved by the PRC Ministry of Commerce or its local counterpart and registered with SAFE or its local counterpart; and (ii) loans to any of our PRC subsidiaries must not exceed the statutory limit, which is the difference between the amount of total investment as approved by the PRC Ministry of Commerce or its local counterpart and the amount of registered capital of the PRC subsidiary, and must be registered with the local counterpart of SAFE. See “Item 3.D. Key Information—Risk Factors—Risks Related to Doing Business in China—PRC regulation of loans to and direct investment in PRC entities by offshore holding companies and governmental control of currency conversion may delay or prevent us from making loans or additional capital contributions to our PRC subsidiaries, which could adversely affect our ability to fund and expand our business.”

As of December 31, 2013, we had RMB17.6 billion (US$2.9 billion) in long-term loans and notes payables (including current portion of RMB343.6 million (US$56.8 million)) and had no short-term loans.

Cash Flows and Working Capital

As of December 31, 2011, 2012 and 2013, we had RMB14.2 billion, RMB32.5 billion and RMB38.4 billion (US$6.3 billion) in cash, cash equivalents and short-term investments.

The following table sets forth a summary of our cash flows for the periods indicated.

|  | For the Years Ended December 31, |

Operating Activities

Net cash generated from operating activities increased to RMB13.8 billion (US$2.3 billion) in 2013 from RMB12.0 billion in 2012. This increase was mainly attributable to the adding-back to net income of increased depreciation and amortization expenses, which increased to RMB2.7 billion (US$438.1 million) in 2013 from RMB1.5 billion in 2012.

Net cash generated from operating activities increased to RMB12.0 billion in 2012 from RMB8.2 billion in 2011. This increase was mainly attributable to the substantial increase in net income to RMB10.4 billion in 2012 from RMB6.6 billion in 2011.

94

##### Table of Contents

Investing Activities

Net cash used in investing activities was about RMB13.8 billion and RMB23.3 billion (US$3.9 billion) in 2012 and 2013, respectively. The increase is primarily due to more acquisitions of businesses accomplished in 2013.

Net cash used in investing activities was about RMB14.3 billion and RMB13.8 billion in 2011 and 2012, respectively. Compared to 2011, our investment of short-term investments increased, while our acquisitions of business decreased in 2012.

Financing Activities

Net cash flow generated from financing activities was RMB7.5 billion (US$1.2 billion) in 2013, compared to a net cash flow of RMB9.5 billion generated from financing activities in 2012. The decrease is primarily due to less long-term notes issued in 2013.

Net cash flow generated from financing activities was RMB9.5 billion (US$1.5 billion) in 2012, compared to a net cash flow of RMB2.4 billion generated from financing activities in 2011, primarily due to the proceeds from the long-term notes issued in 2012.

Holding Company Structure

Baidu, Inc. is a holding company with no operations of its own. We conduct our operations in China primarily through our subsidiaries and consolidated affiliated entities in China. As a result, although other means are available for us to obtain financing at the holding company level, Baidu, Inc.’s ability to pay dividends to the shareholders and to service any debt it may incur may depend upon dividends paid by our PRC subsidiaries and license and service fees paid by our PRC consolidated affiliated entities. If any of our subsidiaries incurs debt on its own behalf in the future, the instruments governing such debt may restrict its ability to pay dividends to Baidu, Inc. In addition, our PRC subsidiaries and consolidated affiliated entities are required to make appropriations to certain statutory reserve funds, which are not distributable as cash dividends except in the event of a solvent liquidation of the companies.

Our PRC subsidiaries, being foreign-invested enterprises established in China, are required to make appropriations to certain statutory reserves, namely, a general reserve fund, an enterprise expansion fund, a staff welfare fund and a bonus fund, all of which are appropriated from net profit as reported in their PRC statutory accounts. Each of our PRC subsidiaries is required to allocate at least 10% of its after-tax profits to a general reserve fund until such fund has reached 50% of its respective registered capital. Appropriations to the enterprise expansion fund and staff welfare and bonus funds are at the discretion of the board of directors of the PRC subsidiaries.

Our consolidated affiliated entities must make appropriations from their after-tax profits as reported in their PRC statutory accounts to non-distributable reserve funds, namely a statutory surplus fund, a statutory public welfare fund and a discretionary surplus fund. Each of our consolidated affiliated entities is required to allocate at least 10% of its after-tax profits to the statutory surplus fund until such fund has reached 50% of its respective registered capital. Appropriations to the statutory public welfare fund and the discretionary surplus fund are at the discretion of our consolidated affiliated entities.

Under PRC laws and regulations, our PRC subsidiaries and consolidated affiliated entities are subject to certain restrictions with respect to paying dividends or otherwise transferring any of their net assets to us. The amounts restricted include the paid up capital and the statutory reserve funds of our PRC subsidiaries and the net assets of our consolidated affiliated entities in which we have no legal ownership, totaling approximately RMB1.2 billion, RMB2.8billion and RMB3.7 billion (US$613.8 million) as of December 31, 2011, 2012 and 2013, respectively.

Capital Expenditures

We made capital expenditures of RMB1.8 billion, RMB2.3 billion and RMB2.8 billion (US$455.4 million) in 2011, 2012 and 2013, representing 12.2%, 10.4% and 8.6% of our total revenues, respectively. In 2013, our capital expenditures were used primarily for the purchase of servers, network equipment, other computer hardware for our business and construction of our office buildings. We funded our capital expenditures primarily with net cash flow generated from operating activities.

We commenced construction of an office building in Shenzhen in December 2011, Baidu Science Park in Beijing in August 2012, and Shanxi Cloud Computing Center in September 2012, and we expect to complete the planned construction of these buildings by the end of 2016, in 2015 and 2017 respectively. See “Item 4.D. Property, Plant and Equipment” for more details of our capital expenditures associated with these projects.

Our capital expenditures may increase substantially in the future as our business continues to grow, in connection with the expansion and improvement of our network infrastructure, and our plan to build additional office buildings and cloud computing based data centers. We currently plan to fund these expenditures with our current cash, cash equivalents, short-term investments and anticipated cash flow generated from our operating activities.

C. Research and Development

We have a team of experienced engineers who are mostly based at our headquarters in Beijing. We recruit most of our engineers locally and have established various recruiting and training programs with leading universities in China. We have also recruited experienced engineers from overseas. We compete aggressively for engineering talent to help us address challenges such as Chinese language processing, information retrieval and high performance computing.

##### Table of Contents

The following paragraphs summarize the key terms of our 2000 option plan, which was amended and restated on December 16, 2008, and our 2008 share incentive plan adopted on December 16, 2008.

2000 Option Plan

Types of Awards. We may grant the following types of awards under our 2000 option plan:

| • |  | our ordinary shares;

| • |  | options to purchase our ordinary shares; and

| • |  | any other securities with value derived from the value of our ordinary shares.

Plan Administration. Our board of directors, or a committee designated by our board of directors, administers our 2000 option plan. In each case, our board of directors or the committee, will determine the provisions and terms and conditions of each award. These include, among other things, the option vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment upon settlement of an award, payment contingencies and satisfaction of any performance criteria.

Award Agreement. Awards granted under our 2000 option plan are evidenced by an award agreement that sets forth the terms, conditions and limitations for each award. In addition, in the case of options, the award agreement also specifies whether the option constitutes an incentive stock option, or ISO, or a non-qualifying stock option.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest. However, we may grant ISOs only to our employees and employees of our majority-owned subsidiaries.

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate upon occurrence of a change-of-control corporate transaction in which the successor entity does not assume our outstanding awards under our 2000 option plan. In such event, each outstanding award will become fully vested and immediately exercisable, the transfer restrictions on the awards will be released (other than those applicable to ISOs), and the repurchase or forfeiture rights will terminate immediately before the date of the change-of-control transaction. If the successor entity assumes our outstanding awards and later terminates the grantee’s employment or service without cause, or if the grantee resigns voluntarily with good cause within 12 months of the change-of-control transaction, the outstanding awards automatically become fully vested and exercisable.

Exercise Price and Term of Awards. If we grant an ISO to an employee, who, at the time of that grant, owns shares representing more than 10% of the voting power of all classes of our share capital, the exercise price cannot be less than 110% of the fair market value of our ordinary shares on the date of that grant. To the extent not prohibited by applicable law or exchange rules, a downward adjustment of the exercise price per share subject to an outstanding option may be made in the absolute discretion of the plan administrator without the approval of our shareholders or the affected grantees.

The term of each award is stated in the award agreement. The term may not exceed ten years from the date of the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of our share capital.

Vesting Schedule. In general, the plan administrator determines, or the award agreement specifies, the vesting schedule. Options generally vest over a four-year period beginning from one year after the grant date. The award agreements may provide that grantees may elect at any time during their employment or service to exercise any part or all of the awards prior to full vesting of the awards. But such early exercise may be subject to a repurchase right as determined by the plan administrator. When an optionee’s employment or service is terminated, the optionee may exercise his or her options that have vested as of the termination date within three months of termination or as determined by our plan administrator.

101

##### Table of Contents

Repurchase Rights. If an award agreement provides for repurchase rights upon termination of a grantee’s employment or service, it must (or may, with respect to awards granted to officers, directors or consultants) provide that (i) such repurchase right must be exercised within 90 days of termination of the grantee’s employment or service (or, in the case of exercise of awards after termination of the grantee’s employment or service, within 90 days following such exercise), (ii) the repurchase price must be equal to the original purchase price paid by the grantee for each such share, and (iii) the right to repurchase will lapse at the rate of at least 20% of the shares subject to the award per year over five years from the date the award is granted (without respect to the date the award was exercised or became exercisable).

Amendment and Termination. Our board of directors may at any time amend, suspend or terminate our 2000 option plan. Amendments to our 2000 option plan are subject to shareholder approval, to the extent required by law, or by stock exchange rules or regulations. Any amendment, suspension or termination of our 2000 option plan must not adversely affect awards already granted without written consent of the recipient of such awards. Our 2000 option plan had a term of ten years from the date of adoption and expired in January 2010.

2008 Share Incentive Plan

Types of Awards. We may grant the following types of awards under our 2008 share incentive plan:

| • |  | options;

| • |  | restricted shares;

| • |  | restricted share units; and

| • |  | any other form of award granted to a participant pursuant to the 2008 plan.

Plan Administration. The compensation committee of our board of directors administers our 2008 share incentive plan, but may delegate to a committee of one or more members of our board of directors the authority to grant or amend awards to participants other than independent directors and executive officers. The compensation committee will determine the provisions and terms and conditions of each award grant, including, but not limited to, the exercise price, the grant price or purchase price, any restrictions or limitations on the award, any schedule for lapse of forfeiture restrictions or restrictions on the exercisability of an award, and accelerations or waivers thereof, any provisions related to non-competition and recapture of gain on an award, based in each case on such considerations as the committee in its sole discretion determines. The compensation committee has the sole power and discretion to cancel, forfeit or surrender an outstanding award (whether or not in exchange for another award or combination or awards).

Award Agreement. Awards granted under our 2008 share incentive plan are evidenced by an award agreement that sets forth the terms, conditions and limitations for each award which may include the term of an award, the provisions applicable in the event the participant’s employment or service ends, and our authority to unilaterally or bilaterally amend, modify, suspend, cancel or rescind an award.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest. However, we may grant ISOs only to our employees and employees of our majority-owned subsidiaries.

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate (i) upon occurrence of a change-of-control corporate transaction where any person acquires at least 50% of the total combined voting power of our outstanding securities or the incumbent board members no longer constitute at least 50% of our board, or (ii) upon occurrence of any other change-of-control corporate transaction in which the successor entity does not assume our outstanding awards under our 2008 share incentive plan, provided that the plan participant remains an employee, consultant or member of our board of directors on the effective date of the

102

##### Table of Contents

corporate transaction. In such event, each outstanding award will become fully exercisable and all forfeiture restrictions on such award will lapse immediately prior to the specified effective date of the corporate transaction.

If the successor entity assumes our outstanding awards and later terminates the grantee’s employment or service without cause within 12 months of the corporate transaction, or if the grantee resigns voluntarily with good reason, the outstanding awards automatically will become fully vested and exercisable. The compensation committee may also, in its sole discretion, upon or in anticipation of a corporate transaction, accelerate awards, purchase the awards from the plan participants, replace the awards, or provide for the payment of the awards in cash.

Exercise Price and Term of Awards. The exercise price per share subject to an option may be amended or adjusted in the absolute discretion of the compensation committee, the determination of which shall be final, binding and conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment of the exercise prices of options mentioned in the preceding sentence shall be effective without the approval of our shareholders or the approval of the affected grantees. If we grant an ISO to an employee, who, at the time of that grant, owns shares representing more than 10% of the voting power of all classes of our share capital, the exercise price cannot be less than 110% of the fair market value of our ordinary shares on the date of that grant. The compensation committee will determine the time or times at which an option may be exercised in whole or in part, including exercise prior to vesting. The term may not exceed ten years from the date of the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of our share capital.

Restricted Shares and Restricted Share Unites. The compensation committee is also authorized to make awards of restricted shares and restricted share units. Except as otherwise determined by the compensation committee at the time of the grant of an award or thereafter, upon termination of employment or service during the applicable restriction period, restricted shares that are at the time subject to restrictions shall be forfeited or repurchased in accordance with the respective award agreements.

Vesting Schedule. The compensation committee determines, and the award agreement specifies, the vesting schedule of options and other awards granted. The compensation committee determines the time or times at which an option may be exercised in whole or in part, including exercise prior to vesting, and also determines any conditions that must be satisfied before all or part of an option may be exercised. At the time of grant for restricted share units, the compensation committee specifies the date on which the restricted share units become fully vested and nonforfeitable, and may specify such conditions to vesting as it deems appropriate.

Amendment and Termination. With the approval of our board of directors, the compensation committee may at any time amend, suspend or terminate our 2008 share incentive plan. Amendments to our 2008 share incentive plan are subject to shareholder approval, to the extent required by law, or by stock exchange rules or regulations. Any amendment, suspension or termination of our 2008 share incentive plan must not adversely affect in any material way awards already granted without written consent of the recipient of such awards. Unless terminated earlier, our 2008 share incentive plan shall continue in effect for a term of ten years from the date of adoption.

C. Board Practices

Board of Directors

Our board of directors has six directors. A director is not required to hold any shares in the company by way of qualification. A director may vote with respect to any contract, proposed contract or arrangement in which he is materially interested. A director may exercise all the powers of the company to borrow money, mortgage its undertakings, property and uncalled capital, and issue debentures or other securities whenever money is borrowed or as security for any obligation of the company or of any third party. The remuneration to be paid to the directors is determined by the board of directors. There is no age limit requirement for directors.

Committees of the Board of Directors

We have three committees under the board of directors: an audit committee, a compensation committee and a corporate governance and nominating committee. We have adopted a charter for each of the three committees.

Audit Committee

Our audit committee consists of William Decker, James Ding and Greg Penner, all of whom satisfy the “independence” requirements of Rule 5605(a)(2) of the NASDAQ Stock Market Rules and Rule 10A-3 under the Exchange Act. Our board of directors has determined that Mr. Decker is an audit committee financial expert as defined in the instructions to Item 16A of the Form 20-F. The audit committee oversees our accounting and financial reporting processes and the audits of the financial statements of our company. The audit committee is responsible for, among other things:

| • |  | appointing, retaining and overseeing the work of the independent auditors, including resolving disagreements between the management and the independent auditors relating to financial reporting;

| • |  | pre-approving all auditing and non-auditing services permitted to be performed by the independent auditors;

| • |  | reviewing annually the independence and quality control procedures of the independent auditors;

| • |  | attending to such other matters that are specifically delegated to our audit committee by our board of directors from time to time.

In 2013, our audit committee held meetings or passed resolutions by unanimous written consent six times.

Compensation Committee

Our compensation committee consists of James Ding and Greg Penner, both of whom satisfy the “independence” requirements of Rule 5605(a)(2) of the NASDAQ Stock Market Rules. The compensation committee assists the board in reviewing and approving our compensation structure, including all forms of compensation relating to our directors and executive officers. Our chief executive officer may not be present at any committee meeting while his compensation is deliberated. The compensation committee is responsible for, among other things:

| • |  | reviewing and approving, or recommending to the board for its approval, the compensation for our chief executive officer and other executive officers;

| • |  | reviewing and recommending to the board for determination with respect to the compensation of our non-employee directors;

| • |  | reviewing periodically and approving any incentive compensation or equity plans, programs or similar arrangements; and

| • |  | selecting compensation consultant, legal counsel or other adviser only after taking into consideration all factors relevant to that person’s independence from management.

In 2013, our compensation committee held meetings or passed resolutions by unanimous written consent five times.

Our corporate governance and nominating committee consists of James Ding and Greg Penner, both of whom satisfy the “independence” requirements of Rule 5605(a) (2) of the NASDAQ Stock Market Rules. The corporate governance and nominating committee assists the board of directors in selecting individuals qualified to become our directors and in determining the composition of the board and its committees. The corporate governance and nominating committee is responsible for, among other things:

| • |  | recommending to the board nominees for election or re-election to the board or for appointments to fill any vacancies;

| • |  | reviewing annually the performance of each incumbent director in determining whether to recommend such director for an additional term;

| • |  | overseeing the board in the board’s annual review of its own performance and the performance of the management; and

| • |  | considering, preparing and recommending to the board such policies and procedures with respect to corporate governance matters as may be required or required to be disclosed under the applicable laws or otherwise considered to be material.

In 2013, our corporate governance and nominating committee held meetings or passed resolutions by unanimous written consent twice.

Terms of Directors and Executive Officers

All directors hold office until their successors have been duly elected and qualified. None of our directors is subject to a fixed term of office. In addition, the service agreements between us and the directors do not provide benefits upon termination of their services. Director nomination is subject to the approval of our corporate governance and nominating committee. Our shareholders may remove any director by ordinary resolution and may in like manner appoint another person in his stead. A valid ordinary resolution requires a majority of the votes cast at a shareholder meeting that is duly constituted and meets the quorum requirement. Officers are elected by and serve at the discretion of the board of directors.

D. Employees

We had 16,082, 20,877 and 31,676 employees as of December 31, 2011, 2012 and 2013, respectively. As of December 31, 2013, we had 1,674 employees in management and administration, 14,055 employees in research and development, 2,779 employees in operation and service, and 13,168 employees in sales and marketing. As of December 31, 2013, we had 19,869 employees in Beijing, 11,711 employees outside of Beijing but within China, and 96 employees outside of China. We also hire temporary employees and contractors from time to time. Our employees are not covered by any collective bargaining agreement. We consider our relations with our employees to be generally good. However, as our operations and employee base further expand, we cannot assure you that we will always be able to maintain good relations with all of our employees. See “Item 3.D. Key Information—Risk Factors—Risks Related to Our Business—We may not be able to manage our expanding operations effectively.”

As of February 28, 2014, 35,036,446 of our ordinary shares were issued and outstanding. To our knowledge, approximately 79.0% of our total outstanding ordinary shares were held by four record shareholders in the United States, including approximately 78.1% held by The Bank of New York Mellon, the depositary of our ADS program. The number of beneficial owners of our ADSs in the United States is likely to be much larger than the number of record holders of our ordinary shares in the United States.

Our subsidiaries, consolidated affiliated entities, and the subsidiaries of the consolidated affiliated entities have engaged, during the ordinary course of business, in a number of customary transactions with each other. All of these inter-company balances have been eliminated in consolidation.

As of December 31, 2013, we had RMB371.0 million (US$61.3 million) due from related parties, which primarily represents the borrowings provided by us to one noncontrolling shareholder of an acquired subsidiary, which were unsecured and repayable on contract terms, and arose in the ordinary course of business. The amount outstanding as of March 28, 2014 was RMB0.1 million (US$17.2 thousand).

As of December 31, 2013, we had RMB373.6 million (US$61.7 million) due to related parties, which primarily represents unsecured and interest free loans provided by a noncontrolling shareholder of an acquired subsidiary, which arose in the ordinary course of business.

Legal Proceedings

From time to time, we have been involved in litigation or other disputes regarding, among other things, copyright and trademark infringement, defamation, unfair competition and labor disputes. Our search results

107

##### Table of Contents

provide links to materials, and our Baidu WenKu, Baidu Post Bar, Baidu Media Player, Baidu Video Search, iQiyi and certain other products or services may contain materials, in which others may allege to own copyrights, trademarks or image rights or which others may claim to be defamatory or objectionable. We have received notice letters from third parties asserting copyright infringement, unfair competition, defamation, breach of contract and labor-related claims against us.

In September 2011, three Chinese writers filed 16 complaints against us before the Haidian District People’s Court in Beijing, alleging that our Baidu WenKu had infringed upon their copyrights to certain literary works. In December 2011, the plaintiffs withdrew their complaints. However, in January 2012, the writers re-filed their complaints for the same claims with the Haidian District People’s Court in Beijing, seeking compensation in an aggregate amount of RMB1.9 million (US$0.3 million). The Haidian District People’s Court in Beijing issued rulings for these cases in September 2012. The court held in seven of these cases that we “should have known” the files uploaded by users to Baidu WenKu infringed upon the plaintiffs’ copyrights and failed to take necessary actions to remove the infringing content immediately despite the plaintiffs’ notification of the infringement and request to remove the infringing content, and ordered us to pay for the plaintiffs’ damages in an aggregate amount of approximately RMB0.2 million (US$28.6 thousand). The court held in these seven cases that we would have been exempted from liabilities if we had removed the infringing content immediately upon the receipt of the warning and removal request from the copyright holders. The court dismissed all plaintiffs’ claims in the other cases. None of the parties has filed any appeals.

In 2013, 125 complaints were filed against Baidu Netcom before various courts in China alleging that our Baidu Video Search had infringed various copyrights. The aggregate amount of the damages sought in these 125 complaints totals approximately RMB16.9 million (US$2.8 million). 37 of these cases are still pending. The other cases are closed, and the aggregate amount of compensation awarded by the courts to the plaintiffs in our lost cases is approximately RMB0.7 million (US$0.1 million).

As of December 31, 2013, we were involved in 210 cases pending in various PRC and U.S. courts. The aggregate amount of compensation sought under these cases is approximately RMB724.6 million (US$119.7 million).

For many of these legal proceedings, we are currently unable to estimate the reasonably possible loss or a range of reasonably possible loss as the proceedings are in the early stages, or there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. As a result, there is considerable uncertainty regarding the timing or ultimate resolution of such proceedings, which includes eventual loss, fine, penalty or business impact, if any, and therefore, an estimate for the reasonably possible loss or a range of reasonably possible loss cannot be made. With respect to the limited number of proceedings for which we are able to estimate the reasonably possible loss or the range of reasonably possible loss, such estimates are immaterial. However, we believe that such proceedings, individually and in the aggregate, when finally resolved, are not reasonably likely to have a material and adverse effect on our results of operations, financial position and cash flows.

Dividend Policy

Baidu, Inc, our holding company in the Cayman Islands, has never declared or paid any dividends on our ordinary shares, nor do we have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business.

Our board of directors has complete discretion as to whether to distribute dividends. Even if our board of directors decides to pay dividends, the form, frequency and amount of our dividends will depend upon our future operations and earnings, capital requirements and surplus, financial condition, contractual restrictions and other factors that our board of directors may deem relevant. If we pay any dividends, we will pay our ADS holders to

108

##### Table of Contents

the same extent as holders of our ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B. Significant Changes

Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the date of our audited consolidated financial statements included in this annual report.

Item 9. The Offer and Listing

A. Offering and Listing Details

Our ADSs have been listed on The NASDAQ Global Market since August 5, 2005. Our ADSs currently trade on The NASDAQ Global Select Market under the symbol “BIDU.” Prior to May 12, 2010, one ADS represented one Class A ordinary share. On May 12, 2010, we effected a change of the ADS to Class A ordinary share ratio from 1 ADS representing 1 Class A ordinary share to 10 ADSs representing 1 Class A ordinary share. The ratio change has the same effect as a 10-for-1 ADS split.

The following table provides the high and low trading prices for our ADSs on NASDAQ for (i) the years 2009, 2010, 2011, 2012 and 2013, (ii) each of the four quarters of 2012 and 2013, and (iii) each of the past six full months. For ease of comparison, the ADS prices before May 12, 2010 have been retroactively adjusted to reflect the ADS to Class A ordinary share ratio change that took effect on May 12, 2010.

Registered Office and Objects

The Registered Office of our company is at the offices of Maples Corporate Services Limited, PO Box 309, Ugland House, Grand Cayman, KY1-1104, Cayman Islands or at such other place as our board of directors may from time to time decide. The objects for which our company is established are unrestricted and we have full power and authority to carry out any object not prohibited by the Companies Law (2013 Revision), as amended from time to time, or any other law of the Cayman Islands.

Board of Directors

See “Item 6.C. Board Practices—Board of Directors.”

Ordinary Shares

General. Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of Class A ordinary shares and Class B ordinary shares have the same rights except for voting and conversion rights. All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders who are nonresidents of the Cayman Islands may freely hold and vote their shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors subject to the Companies Law.

Conversion. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances.

110

##### Table of Contents

Upon any transfer of Class B ordinary shares by a holder thereof to any person or entity which is not an affiliate of such holder (as defined in our articles of incorporation), such Class B ordinary shares shall be automatically and immediately converted into the equal number of Class A ordinary shares. In addition, if at any time our chairman and chief executive officer, Robin Yanhong Li, and his affiliates collectively own less than 5% of the total number of the issued and outstanding Class B ordinary shares, each issued and outstanding Class B ordinary share shall be automatically and immediately converted into one share of Class A ordinary share, and we shall not issue any Class B ordinary shares thereafter.

Voting Rights. All of our shareholders have the right to receive notice of shareholders’ meetings and to attend, speak and vote at such meetings. In respect of matters requiring shareholders’ vote, each Class A ordinary share is entitled to one vote, and each Class B ordinary share is entitled to 10 votes. A shareholder may participate at a shareholders’ meeting in person, by proxy or by telephone conference or other communications equipment by means of which all the shareholders participating in the meeting can communicate with each other. At any shareholders’ meeting, a resolution put to the vote of the meeting shall be decided on a poll conducted by the chairman of the meeting.

A quorum for a shareholders’ meeting consists of one or more shareholders holding at least one third of the paid up voting share capital present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative. We shall, if required by the Companies Law, hold a general meeting of shareholders as our annual general meeting and shall specify the meeting as such in the notices calling it. Our board of directors may call extraordinary general meetings, and they must on shareholders’ requisition convene an extraordinary general meeting. A shareholder requisition is a requisition of shareholders holding at the date of deposit of the requisition not less than a majority of the voting power represented by the issued shares of our company as at that date carries the right of voting at general meetings of our company. Advance notice of at least five days is required for the convening of our annual general meeting and other shareholders’ meetings.

An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the ordinary shares cast in a general meeting. A special resolution is required for matters such as a change of name. Holders of the ordinary shares may effect certain changes by ordinary resolution, including consolidating and dividing all or any of our share capital into shares of larger amount than our existing share capital and canceling any shares.

Transfer of Shares. Subject to the restrictions of our memorandum and articles of association, as applicable, any of our shareholders may transfer any or all of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board of directors.

Our board of directors may, in their absolute discretion (except with respect to a transfer from a shareholder to its affiliate(s)), decline to register any transfer of shares without assigning any reason thereof. If our board of directors refuses to register a transfer they shall notify the transferee within two months of such refusal. Notwithstanding the foregoing, if a transfer complies with the holder’s transfer obligations and restrictions set forth under applicable law (including but not limited to U.S. securities law provisions related to insider trading) and our articles of association, our board of directors shall promptly register such transfer. Further, any director is authorized to confirm in writing addressed to the registered office to authorize a share transfer and to instruct that the register of members be updated accordingly, provided that the transfer complies with the holder’s transfer obligations and restrictions set forth under applicable law and our articles of association and such holder is not the director who authorizes the transfer or an entity affiliated with such director. Any director is authorized to execute a share certificate in respect of such shares for and on behalf of our company.

The registration of transfers may be suspended at such time and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended for more than 45 days in any year.

111

##### Table of Contents

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of shares), assets available for distribution among the holders of ordinary shares may be distributed among the holders of the ordinary shares as determined by the liquidator, subject to sanction of a special resolution of our company. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately to the capital paid up, or which ought to have been paid up, at the commencement of the winding up on the shares held by such shareholders respectively.

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 days prior to the specified time and place of payment. The shares that have been called upon and remain unpaid on the specified time are subject to forfeiture.

Redemption of Shares. Subject to the provisions of the Companies Law and our articles of association, we may issue shares on terms that are subject to redemption, at our option or at the option of the holders, on such terms and in such manner as our board of directors may determine.

Repurchase of Shares. Subject to the provisions of the Companies Law and our articles of association, our board of directors may authorize repurchase of our shares in accordance with the manner of purchase specified in our articles of association without seeking shareholder approval.

Variations of Rights of Shares. All or any of the special rights attached to any class of shares may, subject to the provisions of the Companies Law, be varied either with the written consent of the holders of a majority of the issued shares of that class or with the sanction of a special resolution passed at a general meeting of the holders of the shares of that class.

Inspection of Books and Records. No holders of our ordinary shares who is not a director shall have any right of inspecting any of our accounts, books or documents except as conferred by the Companies Law or authorized by the directors or by us in general meeting. However, we will make this annual report, which contains our audited financial statements, available to shareholders and ADS holders. See “Item 10.H. Additional Information—Documents on Display.”

Preferred Shares

Our board of directors has the authority, without shareholder approval, to issue up to a total of 10,000,000 shares of preferred shares in one or more series. Our board of directors may establish the number of shares to be included in each such series and may set the designations, preferences, powers and other rights of the shares of a series of preferred shares. While the issuance of preferred shares provides us with flexibility in connection with possible acquisitions or other corporate purposes, it could, among other things, have the effect of delaying, deferring or preventing a change of control transaction and could adversely affect the market price of our ADSs. We have no current plan to issue any preferred shares.

C. Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than those described in “Item 4. Information on the Company” or elsewhere in this annual report on Form 20-F.

D. Exchange Controls

See “Item 4.B. Information on the Company—Business Overview—Regulation—Regulations on Foreign Exchange.”

##### Table of Contents

E. Taxation

The following summary of the material Cayman Islands, People’s Republic of China and United States federal income tax consequences of an investment in our ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this annual report, all of which are subject to change. This summary does not deal with all possible tax consequences relating to an investment in our ADSs or ordinary shares, such as the tax consequences under state, local and other tax laws.

Cayman Islands Taxation

According to Maples and Calder, our Cayman Islands counsel, the Cayman Islands currently levies no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within, the jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties that are applicable to any payments made to or by our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

People’s Republic of China Taxation

If we are considered a PRC resident enterprise under the EIT Law, our shareholders and ADS holders who are deemed non-resident enterprises may be subject to the 10% EIT on the dividends payable by us or any gains realized from the transfer of our shares or ADSs, if such income is deemed derived from China, provided that (i) such foreign enterprise investor has no establishment or premises in China, or (ii) it has establishment or premises in China but its income derived from China has no real connection with such establishment or premises. Furthermore, if we are considered a PRC resident enterprise and relevant PRC tax authorities consider the dividends we pay with respect to our shares or ADSs and the gains realized from the transfer of our shares or ADSs to be income derived from sources within the PRC, it is also possible that such dividends and gains earned by non-resident individuals may be subject to the 20% PRC individual income tax. It is uncertain whether, if we are considered a PRC resident enterprise, holders of our shares or ADSs would be able to claim the benefit of tax treaties or arrangements entered into between China and other jurisdictions.

If we are required under the PRC tax law to withhold PRC income tax on our dividends payable to our non-PRC resident shareholders and ADS holders, or if any gains realized from the transfer of our shares or ADSs by our non-PRC resident shareholders and ADS holders are subject to the EIT or the individual income tax, your investment in our shares or ADSs could be materially and adversely affected.

United States Federal Income Taxation

The following discussion describes certain U.S. federal income tax considerations under present law of the purchase, ownership and disposition of the ADSs or ordinary shares. This summary applies only to investors that are U.S. Holders (as defined below) and that hold the ADSs or ordinary shares as capital assets. This discussion is based on the tax laws of the United States as in effect on the date of this annual report on Form 20-F and on U.S. Treasury regulations in effect or, in some cases, proposed, as of the date of this annual report on Form 20-F, as well as judicial and administrative interpretations thereof available on or before such date. All of the foregoing authorities are subject to change, which change could apply retroactively and could affect the tax considerations described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:

| • |  | banks;

U.S. Holders are urged to consult their tax advisors about the application of the U.S. federal tax rules to their particular circumstances as well as the state and local and foreign tax consequences to them of the purchase, ownership and disposition of ADSs or ordinary shares.

The discussion below of the U.S. federal income tax consequences will apply if you are a “U.S. Holder.” You are a “U.S. Holder” if you are the beneficial owner of ADSs or ordinary shares and you are, for U.S. federal income tax purposes,

| • |  | a citizen or individual resident of the United States;

| • |  | a corporation (or other entity subject to tax as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of the United States, any State or the District of Columbia;

| • |  | an estate whose income is subject to U.S. federal income taxation regardless of its source; or

| • |  | a trust that (i) is subject to the supervision of a court within the United States and the control of one or more United States persons or (ii) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person.

This discussion does not consider the tax treatment of partnerships or other pass-through entities that hold the ADSs or ordinary shares, or of persons who hold the ADSs or ordinary shares through such entities. If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of the ADSs or ordinary shares, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. If you hold ADSs, you will be treated as the holder of the underlying ordinary shares represented by those ADSs for U.S. federal income tax purposes.

This discussion does not address any aspect of U.S. federal non-income tax laws, such as gift or estate tax laws, or state, local or non-U.S. tax laws. We have not sought, and will not seek, a ruling from the Internal Revenue Service (the “IRS”), or an opinion as to any U.S. federal income tax consequence described herein. The IRS may disagree with the discussion herein, and its determination may be upheld by a court.

Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares

Subject to the passive foreign investment company rules discussed below, the gross amount of all our distributions to you with respect to the ADSs or ordinary shares will be included in your gross income as dividend income on the date of receipt by the depositary, in the case of ADSs, or by you, in the case of ordinary shares, but only to the extent that the distribution is paid out of our current or accumulated earnings and profits (computed under U.S. federal income tax principles). Because we do not intend to determine our earnings and profits on the basis of U.S. federal income tax principles, any distribution paid will generally be treated as a “dividend” for U.S. federal income tax purposes. Dividends paid by us will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from U.S. corporations.

With respect to non-corporate U.S. Holders (including individual U.S. Holders), dividends may be taxed at the lower applicable capital gains rate provided that (i) the ADSs or ordinary shares are readily tradable on an established securities market in the United States or we are eligible for the benefit of the income tax treaty between the United States and the PRC, (ii) we are not a passive foreign investment company (as discussed below) for either our taxable year in which the dividend was paid or the preceding taxable year, (iii) certain holding period requirements are met, and (iv) such non-corporate U.S. Holders are not under an obligation to make related payments with respect to positions in substantially similar or related property. For this purpose, ADSs listed on the NASDAQ Global Select Market will generally be considered to be readily tradable on an established securities market in the United States. You should consult your tax advisor regarding the availability of the lower rate for dividends paid with respect to our ADSs or ordinary shares.

For U.S. foreign tax credit purposes, dividends paid on the ADSs or ordinary shares generally will be treated as income from foreign sources and generally will constitute passive category income. If PRC withholding taxes apply to dividends paid to you with respect to the ADSs or ordinary shares, you may be able to obtain a reduced rate of PRC withholding taxes under the income tax treaty between the United States and the PRC if certain requirements are met. In addition, subject to certain conditions and limitations, PRC withholding taxes on dividends may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. If you do not elect to claim a foreign tax credit, you may instead claim a deduction for U.S. Holders federal income tax purposes in respect of such withholding, but only for a year in which you elect to do so for all creditable foreign income taxes. You should consult your tax advisor regarding the creditability of any PRC tax.

Sale, Exchange or Other Disposition of the ADSs or ordinary shares

Subject to the passive foreign investment company rules discussed below, you will recognize gain or loss on any sale, exchange or other taxable disposition of an ADS or ordinary share equal to the difference between the amount realized for the ADS or ordinary share and your tax basis in the ADS or ordinary share. The gain or loss will generally be capital gain or loss. If you are a non-corporate U.S. Holder, including an individual U.S. Holder, who has held the ADS or ordinary share for more than one year, you will generally be eligible for reduced tax rates. The deductibility of capital losses is subject to limitations. Any such gain or loss that you recognize will generally be treated as U.S. source income or loss (in the case of losses, subject to certain limitations). However, in the event we are deemed to be a PRC “resident enterprise” under PRC tax law, we may be eligible for the benefits of the income tax treaty between the United States and the PRC. In such event, if PRC tax were to be imposed on any gain from the disposition of the ADSs or ordinary shares, a U.S. Holder that is eligible for the benefits of the income tax treaty between the United States and the PRC may elect to treat such gain as PRC source income. U.S. Holders should consult their own tax advisors regarding the creditability of any PRC tax.

Passive Foreign Investment Company

Based on the market price of our ADSs and ordinary shares, the value of our assets, and the composition of our assets and income, we believe that we were not a “passive foreign investment company,” or “PFIC,” for our

115

##### Table of Contents

taxable year ended December 31, 2013 and we do not expect to be a PFIC for our taxable year ending December 31, 2014 or for the foreseeable future. However, our PFIC status for the current taxable year ending December 31, 2014 will not be determinable until its close, and, accordingly, there is no guarantee that we will not be a PFIC for the current taxable year (or any future taxable year). A non-U.S. corporation is considered a PFIC for any taxable year if either:

| • |  | at least 75% of its gross income is passive income (the “income test”), or

| • |  | at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income (the “asset test”).

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 shares.

We must make a separate determination each year as to whether we are a PFIC. As a result, our PFIC status may change. In particular, because the total value of our assets for purposes of the asset test will generally be calculated using the market price of the ADSs and ordinary shares, our PFIC status will depend in large part on the market price of the ADSs and ordinary shares, which may fluctuate considerably. Accordingly, fluctuations in the market price of the ADSs and ordinary shares may result in our being a PFIC for any year. If we are a PFIC for any year during which you hold the ADS or ordinary shares, we will generally continue to be treated as a PFIC for all succeeding years during which you hold such ADS or ordinary shares. However, if we cease to be a PFIC, provided that you have not made a mark-to-market election, as described below, you may avoid some of the adverse effects of the PFIC regime by making a deemed sale election with respect to the ADSs or ordinary shares, as applicable.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary shares, you will be subject to special tax rules with respect to any “excess distribution” that you receive and any gain you realize from a sale or other disposition (including a pledge) of the ADSs or ordinary shares, unless you make a “mark-to-market” election as discussed below. Distributions you receive in a taxable year that are greater than 125% of the average annual distributions you received during the shorter of the three preceding taxable years or your holding period for the ADSs or ordinary shares will be treated as an excess distribution. Under these special tax rules:

| • |  | the excess distribution or gain will be allocated ratably over your holding period for the ADSs or ordinary shares,

| • |  | the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary income, and

| • |  | the amount allocated to each of the other taxable years would be subject to tax at the highest rate of tax in effect for you for such year and would be increased by an additional tax equal to interest on the resulting tax deemed deferred with respect to each such other taxable year.

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the ADSs or ordinary shares cannot be treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market election for such stock of a PFIC to elect out of the tax treatment discussed in the two preceding paragraphs. If you make a valid mark-to-market election for the ADSs or ordinary shares, you will include in income each year an amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares as of the close of your taxable year over your adjusted basis in such ADSs or ordinary shares. You are allowed a deduction for the excess, if any, of the adjusted basis of the ADSs or ordinary shares over their fair market value as of the close of the taxable year. Such deductions, however, are allowable only to the extent of any net mark-to-

116

##### Table of Contents

market gains on the ADSs or ordinary shares included in your income for prior taxable years. Amounts included in your income under a mark-to-market election, as well as gain on the actual sale or other disposition of the ADSs or ordinary shares, are treated as ordinary income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ADSs or ordinary shares, as well as to any loss realized on the actual sale or disposition of the ADSs or ordinary shares, to the extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such ADSs or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss amounts. If you make such a mark-to-market election, tax rules that apply to distributions by corporations which are not PFICs would apply to distributions by us (except that the lower applicable capital gains rate would not apply).

The mark-to-market election is available only for “marketable stock” which is stock that is traded in other than de minimis quantities on at least 15 days during each calendar quarter, or “regularly traded,” on a qualified exchange or other market, as defined in applicable Treasury regulations. We expect that the ADSs will continue to be listed on the NASDAQ Global Select Market, which is a qualified exchange for these purposes, and, consequently, assuming that the ADSs are regularly traded, if you are a holder of ADSs, it is expected that the mark-to-market election would be available to you were we to become a PFIC.

Because, as a technical matter, a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder may continue to be subject to the general PFIC rules described above with respect to such U.S. Holder’s indirect interest in any investments held by us that are treated as an equity interest in a PFIC for United States federal income tax purposes.

Alternatively, a U.S. Holder may avoid the PFIC tax consequences described above in respect to its ADSs and ordinary shares by making a timely “qualified electing fund,” or QEF, election. In order to comply with the requirements of a QEF election, a U.S. Holder must receive certain information from us. Because we do not intend to provide such information, however, such election will not be available to you with respect to the ADSs or ordinary shares.

If you hold ADSs or ordinary shares in any year in which we are a PFIC, you will be required to file an annual information report containing such information as the U.S. Treasury may require.

You are urged to consult your tax advisor regarding the application of the PFIC rules to your investment in ADSs or ordinary shares.

Medicare Tax

An additional 3.8% tax is imposed on a portion or all of the net investment income of certain individuals with a modified adjusted gross income of over $200,000 (or $250,000 in the case of joint filers or $125,000 in the case of married individuals filing separately) and on the undistributed net investment income of certain estates and trusts. For these purposes, “net investment income” generally includes interest, dividends (including dividends paid with respect to the ADSs or ordinary shares), annuities, royalties, rents, net gain attributable to the disposition of property not held in a trade or business (including net gain from the sale, exchange or other taxable disposition of an ADS or ordinary share) and certain other income, reduced by any deductions properly allocable to such income or net gain. U.S. Holders are urged to consult their tax advisors regarding the applicability of this tax to their income and gains in respect of an investment in the ADSs or ordinary shares.

Information Reporting and Backup Withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds from the sale, exchange or redemption of ADSs or ordinary shares may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply to you, however, if you furnish a correct taxpayer identification number and make any other required certification or that are otherwise exempt from backup

117

##### Table of Contents

withholding. U.S. Holders that are required to establish their exempt status generally must provide such certification on IRS Form W-9. You should consult your tax advisor regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding can be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information in a timely manner.

Individual U.S. Holders and certain entities may be required to submit to the IRS certain information with respect to his or her beneficial ownership of the ADSs or ordinary shares, if such ADSs or ordinary shares are not held on his or her behalf by a financial institution. This law also imposes penalties if an individual U.S. Holder is required to submit such information to the IRS and fails to do so.

We previously filed with the SEC our registration statement on Form F-1, as amended and prospectus under the Securities Act of 1933, with respect to our ordinary shares. We have also previously filed with the SEC our registration statement on Form F-3 with respect to the sale of debt securities by our company on a continuous basis, a prospectus under the Securities Act with respect to our issuance of US$1.5 billion senior unsecured notes in two equal tranches, due in 2017 and 2022 with stated interest rates of 2.25% and 3.50%, respectively, and a prospectus under the Securities Act with respect to our issuance of US$1.0 billion senior unsecured notes due in 2018 with stated interest rates of 3.25%.

We are subject to the periodic reporting and other informational requirements of the Securities Exchange Act. Under the Exchange Act, we are required to file reports and other information with the SEC. Specifically, we are required to file annually a Form 20-F within four months after the end of each fiscal year, which is December 31. Copies of reports and other information, when so filed, may be inspected without charge and may be obtained at prescribed rates at the public reference facilities maintained by the SEC at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. The public may obtain information regarding the Washington, D.C. Public Reference Room by calling the Commission at 1-800-SEC-0330. The SEC also maintains a website at www.sec.gov that contains reports, proxy and information statements, and other information regarding registrants that make electronic filings with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act.

We will furnish The Bank of New York Mellon, the depositary of our ADSs, with our annual reports, which will include a review of operations and annual audited consolidated financial statements prepared in conformity with U.S. GAAP, and all notices of shareholders’ meetings and other reports and communications that are made generally available to our shareholders. The depositary will make such notices, reports and communications available to holders of ADSs and, upon our request, will mail to all record holders of ADSs the information contained in any notice of a shareholders’ meeting received by the depositary from us.

I. Subsidiary Information

Item 11. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

Our exposure to interest rate risk primarily relates to excess cash invested in short-term instruments with original maturities of less than a year. Investments in both fixed rate and floating rate interest earning instruments carry a degree of interest rate risk. Fixed rate securities may have their fair market value adversely impacted due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates, or we may suffer losses in principal if we have to sell securities which have declined in market value due to changes in interest rates. We have not been, and do not expect to be, exposed to material interest rate risks, and therefore have not used any derivative financial instruments to manage our interest risk exposure.

We had RMB28.7 billion (US$4.7 billion) short-term investments as of December 31, 2013, with a weighted average duration of approximately 0.38 years. A hypothetical one percentage point (100 basis-point) increase in interest rates would have resulted in a decrease of approximately RMB106.8 million (US$17.6 million) in the fair value of these short-term investments as of December 31, 2013.

Foreign Exchange Risk

Most of our revenues and costs are denominated in RMB, while a portion of our cash and cash equivalents and short-term financial assets are denominated in U.S. dollars and held by our Cayman Islands holding company. Our exposure to foreign exchange risk primarily relates to those financial assets denominated in U.S. dollars. Any significant revaluation of RMB against the U.S. dollar may materially affect our earnings and financial position, and the value of, and any dividends payable on, our ADS in U.S. dollars. See “Item 3.D. Key Information—Risk Factors—Risks Related to Doing Business in China—Fluctuation in the value of the RMB may have a material and adverse effect on your investment.” In addition, we commenced operation in Japan in late 2007. To the extent we need to make capital injections into our Japan operation by converting U.S. dollars into Japanese Yen, we will be exposed to the fluctuations in the exchange rate between the U.S. dollar and the Japanese Yen. We have not hedged exposures denominated in foreign currencies using any derivative financial instruments.

The RMB appreciated by 2.9% against the U.S. dollar in 2013. A hypothetical 10% decrease in the exchange rate of the U.S. dollar against the RMB would have resulted in a decrease of RMB489.6 million (US$80.9 million) in the value of our U.S. dollar-denominated financial assets at December 31, 2013.

Fees and Charges Our ADS holders May Have to Pay

The Bank of New York Mellon, the depositary of our ADS program, collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deductions from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid. The depositary’s corporate trust office at which the ADSs will be administered is located at 101 Barclay Street, New York, New York 10286. The depositary’s principal executive office is located at One Wall Street, New York, New York 10286.

Persons depositing or withdrawing shares must pay: |  | For:
US$5.00 (or less) per 1,000 ADSs (or portion of 1,000 ADSs) |  | • Issuance of ADSs, including issuances resulting from a distribution of shares or rights or other property
|  | • Cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates
US$0.02 (or less) per ADS |  | • Any cash distribution to registered ADS holders
A fee equivalent to the fee that would be payable if securities distributed had been shares and the shares had been deposited for issuance of ADSs |  | • Distribution of securities distributed to holders of deposited securities which are distributed by the depositary to registered ADS holders
US$0.02 (or less) per ADS per calendar year (if the depositary has not collected any cash distribution fee during that year) |  | • Depositary services
Expenses of the depositary |  | • Cable, telex and facsimile transmissions (when expressly provided in the deposit agreement)
|  | • Converting foreign currency to U.S. dollars
Registration or transfer fees |  | • Transfer and registration of shares on our share register to or from the name of the depositary or its agent when you deposit or withdraw shares
Taxes and other governmental charges the depositary or the custodian have to pay on any ADS or share underlying an ADS, for example, stock transfer taxes, stamp duty or withholding taxes |  | • As necessary
Any charges incurred by the depositary or its agents for servicing the deposited securities |  | • As necessary

Fees and Other Payments Made by the Depositary to Us

The depositary has agreed to reimburse us annually for our expenses incurred in connection with investor relationship programs and any other program related to our ADS facility and the travel expense of our key personnel in connection with such programs. The depositary has also agreed to provide additional payments to us based on the applicable performance indicators relating to our ADS facility. There are limits on the amount of expenses for which the depositary will reimburse us, but the amount of reimbursement available to us is not necessarily tied to the amount of fees the depositary collects from investors. In 2014, we expect to receive approximately US$4.0 million (after tax) reimbursement from the depositary for our expenses incurred in connection with investor relationship programs related to the ADS facility and the travel expense of our key personnel in connection with such programs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, has performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this report, as required by Rule 13a-15(b) under the Exchange Act.

Based upon that evaluation, our management has concluded that, as of December 31, 2013, our disclosure controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports that we file and furnish under the Exchange Act was recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act. Our management evaluated the effectiveness of our internal control over financial reporting, as required by Rule 13a-15(c) of the Exchange Act, based on criteria established in the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Our management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of 91 Wireless Websoft Limited, which is included in the 2013 consolidated financial statements of Baidu, Inc. and constituted RMB11.9 billion (US$2.0 billion) and RMB11.3 billion (US$1.9 billion) of total and net assets, respectively, as of December 31, 2013 and RMB259.8 million (US$42.9 million) and RMB27.8 million (US$4.6 million) of revenues and net income, respectively. Based on this evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, 2013.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness of our internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Our independent registered public accounting firm, Ernst & Young Hua Ming LLP, has audited the effectiveness of our internal control over financial reporting as of December 31, 2013, as stated in its report, which appears on page F-3 of this annual report on Form 20-F.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting that occurred during the period covered by this annual report on Form 20-F that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 16C. Principal Accountant Fees and Services

The following table sets forth the aggregate fees by categories specified below in connection with certain professional services rendered by Ernst & Young Hua Ming LLP, our principal external auditors, for the periods indicated.

|  | 2012 |  |  | 2013 |
Audit fees(1) |  | US$ | 1,874,270 |  |  | US$ | 3,444,858 |
Audit-related fees(2) |  | US$ | 85,688 |  |  |  | — |
Tax fees(3) |  | US$ | 11,139 |  |  | US$ | 46,146 |
All other fees(4) |  |  | — |  |  | US$ | 2,153 |

(1) | “Audit fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered by our principal auditors for the audit of our annual financial statements and assistance with and review of documents filed with the SEC. In 2012 and 2013, the audit refers to financial audit and audit pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

(2) | “Audit-related fees” means fees billed in year 2012 for professional services rendered by our principal auditors associated with certain due diligence projects.

(3) | “Tax fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered by our principal auditors for tax compliance, tax advice, and tax planning. In 2012 and 2013, the tax fees refer to fees paid to our principal auditors for reviewing the compliance of our tax documentation and providing tax advices.

(4) | “All other fees” means the aggregate fees billed in 2013 for our subscription of certain U.S. GAAP reading materials from our principal auditors.

All audit and non-audit services provided by our independent auditors must be pre-approved by our audit committee. Our audit committee has adopted a combination of two approaches in pre-approving proposed services: general pre-approval and specific pre-approval. With general approval, proposed services are pre-approved without consideration of specific case-by-case services; with specific approval, proposed services require the specific pre-approval of the audit committee. Unless a type of service has received general pre-approval, it will require specific pre-approval by our audit committee. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by our audit committee.

All requests or applications for services to be provided by our independent auditors that do not require specific approval by our audit committee will be submitted to our chief financial officer and must include a detailed description of the services to be rendered. The chief financial officer will determine whether such services are included within the list of services that have received the general pre-approval of the audit committee. The audit committee will be informed on a timely basis of any such services. Requests or applications to provide services that require specific approval by our audit committee will be submitted to the audit committee by both our independent auditors and our chief financial officer and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC’s rules on auditor independence.

NASDAQ Stock Market Rule 5620 requires each issuer to hold an annual meeting of shareholders no later than one year after the end of the issuer’s fiscal year-end. However, NASDAQ Stock Market Rule 5615(a)(3) permits foreign private issuers like us to follow “home country practice” in certain corporate governance matters. Maples and Calder, our Cayman Islands counsel, has provided a letter to the NASDAQ Stock Market certifying that under Cayman Islands law, we are not required to hold annual shareholder meetings every year. We follow home country practice with respect to annual meetings and did not hold an annual meeting of shareholders in 2013. We may, however, hold annual shareholder meetings in the future if there are significant issues that require shareholders’ approvals.

Other than the annual meeting practice described above, there are no significant differences between our corporate governance practices and those followed by U.S. domestic companies under NASDAQ Stock Market Rules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Baidu, Inc.

We have audited the accompanying consolidated balance sheets of Baidu, Inc. (the “Company”) as of December 31, 2013 and 2012, and the related consolidated statements of comprehensive income, shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Baidu, Inc. at December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Baidu, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) and our report dated March 28, 2014 expressed an unqualified opinion thereon.

We have audited Baidu, Inc.’s internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). Baidu, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of 91 Wireless Websoft Limited, which is included in the 2013 consolidated financial statements of Baidu, Inc. and constituted RMB11.94 billion and RMB11.25 billion of total and net assets, respectively, as of December 31, 2013 and RMB259.84 million and RMB27.84 million of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of Baidu, Inc. also did not include an evaluation of the internal control over financial reporting of 91 Wireless Websoft Limited.

In our opinion, Baidu, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Baidu, Inc. as of December 31, 2013 and 2012, and the related consolidated statements of comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013 of Baidu, Inc., and our report dated March 28, 2014 expressed an unqualified opinion thereon.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2011, 2012 and 2013

1. | ORGANIZATION, CONSOLIDATION AND PRESENTATION OF FINANCIAL STATEMENTS

Baidu, Inc. (“Baidu” or the “Company”) was incorporated under the laws of the Cayman Islands on January 18, 2000.

As of December 31, 2013, the Company has wholly-owned and majority-owned subsidiaries incorporated in countries and jurisdictions including the People’s Republic of China (“PRC”), Hong Kong, Japan, the United States of America (“USA”), Cayman Islands and British Virgin Islands (“BVI”). As of December 31, 2013, the Company also effectively controls a number of variable interest entities (“VIE”) through the Primary Beneficiaries, as defined below. The VIEs include:

| • |  | Beijing Baidu Netcom Science Technology Co., Ltd. (“Baidu Netcom”), controlled through Baidu Online Network Technology (Beijing) Co., Ltd. (“Baidu Online”), one of the Company’s wholly-owned subsidiaries;

| • |  | Beijing Perusal Technology Co., Ltd. (“Beijing Perusal”), controlled through Baidu Online; and

| • |  | Beijing BaiduPay Science and Technology Co., Ltd. (“BaiduPay”), controlled through Baidu Online; and

| • |  | Other VIEs controlled through Primary Beneficiaries other than Baidu Online.

The Company, its wholly-owned and majority-owned subsidiaries, VIEs and wholly-owned subsidiaries of the VIEs are hereinafter collectively referred to as the “Group.” The Group offers internet search solutions and online marketing solutions, operates an online payment platform which enables users to make payments online, develops and markets scalable web/mobile application software and provides related services, conducts online advertising business in connection with online video contents broadcasting, provides mobile application distribution services and provides group buying services. The Group’s principal geographic market is in the PRC. The Company does not conduct any substantive operations of its own but conducts its primary business operations through its wholly-owned and majority-owned subsidiaries and VIEs in the PRC.

PRC laws and regulations prohibit or restrict foreign ownership of internet content, advertising, and audio and video services. To comply with these foreign ownership restrictions, the Group operates its websites and primarily provides services subject to such restriction in the PRC through the VIEs, the PRC legal entities that were established or whose equity shares were held by the individuals authorized by the Group. The paid-in capital of the VIEs was mainly funded by the Group through loans extended to the authorized individuals who were the shareholders of the VIEs. The Group has entered into proxy agreements or power of attorney and exclusive equity purchase option agreement with the VIEs and nominee shareholders of the VIEs through the Group’s subsidiaries (“Primary Beneficiaries”), which give the Primary Beneficiaries the rights to direct the activities that most significantly affect the economic performance of the VIEs and to acquire the equity interests in the VIEs when permitted by the PRC laws, respectively. Certain exclusive agreements have been entered into with the VIEs through the Primary Beneficiaries or their wholly-owned subsidiaries in the PRC, which obligate the Primary Beneficiaries to absorb a majority of the risk of loss from the VIEs’ activities and entitle the Primary Beneficiaries to receive a majority of their residual returns. In addition, the Group has entered into certain agreements with the shareholders of the VIEs through the Primary Beneficiaries or their wholly-owned subsidiaries in the PRC, including loan agreements for the paid-in capital of the VIEs and share pledge agreements for the equity interests in the VIEs held by the shareholders of the VIEs.

Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Primary Beneficiaries and the VIEs through the aforementioned agreements with the shareholders of the VIEs. The shareholders of the VIEs effectively assigned all of their voting rights underlying their equity interest in the VIEs to the Primary Beneficiaries. In addition, through the other exclusive agreements, which

consist of operating agreements, technology consulting and services agreements and license agreements, the Primary Beneficiaries, by themselves or their wholly-owned subsidiaries in the PRC, demonstrate their ability and intention to continue to exercise the ability to absorb substantially all of the profits and all of the expected losses of the VIEs. The VIEs are subject to operating risks, which determine the variability of the Company’s interest in those entities. Based on these contractual arrangements, the Company consolidates the VIEs as required by SEC Regulation SX-3A-02 and Accounting Standards Codification (“ASC”) topic 810 (“ASC 810”), Consolidation, because the Company holds all the variable interests of the VIEs through the Primary Beneficiaries.

The principal terms of the agreements entered into amongst the VIEs, their respective shareholders and the Primary Beneficiaries are further described below.

Loan Agreements

Pursuant to loan agreements amongst the shareholders of Baidu Netcom and Baidu Online, Baidu Online provided interest-free loans with an aggregate amount of RMB100.0 million to the shareholders of Baidu Netcom solely for the latter to fund the capitalization of Baidu Netcom. The loans can be repaid only with the proceeds from sale of the shareholders’ equity interest in Baidu Netcom to Baidu Online or its designated person. The terms of the loan agreements will expire on April 26, 2014 at the earliest and can be extended with the written consent of both parties before its expiration.

Each of the loan agreements amongst Baidu Online and the respective shareholders of Beijing Perusal and BaiduPay contains the same terms as those described above, except that the amount of the loans extended to the respective shareholders is RMB10.0 million and RMB9.0 million, respectively. The term of the loan agreements will expire on January 15, 2022 and April 22, 2022, respectively, and can be extended with the written consent of both parties before its expiration.

Exclusive Equity Purchase and Transfer Option Agreement

Pursuant to the exclusive equity purchase and transfer option agreement amongst the shareholders of Baidu Netcom, Baidu Netcom and Baidu Online, the shareholders of Baidu Netcom irrevocably granted Baidu Online or its designated person(s) an exclusive option to purchase, to the extent permitted under PRC law, all or part of the equity interests in Baidu Netcom for the cost of the initial contributions to the registered capital or the minimum amount of consideration permitted by applicable PRC law. The shareholders should remit to Baidu Online any amount that is paid by Baidu Online or its designated person(s) in connection with the purchased equity interest. Baidu Online or its designated person(s) have sole discretion to decide when to exercise the option, whether in part or in full. Any and all dividends and other capital distributions from Baidu Netcom to its shareholders should be paid to Baidu Online in full amount. Baidu Online would provide unlimited financial support to Baidu Netcom if, in the normal operation of business, Baidu Netcom would become in need of any form of reasonable financial support. If Baidu Netcom were to incur any loss and as a result cannot repay any loans from Baidu Online, Baidu Online should unconditionally forgive any such loans to Baidu Netcom given that Baidu Netcom provides sufficient proof for its loss and incapacity to repay. The agreement will terminate when the shareholders of Baidu Netcom have transferred all their equity interests in Baidu Netcom to Baidu Online or its designated person(s) or upon expiration of the term of business of Baidu Online or Baidu Netcom.

Equity Pledge Agreement

Pursuant to the equity pledge agreement between Baidu Online and the shareholders of Baidu Netcom, the shareholders of Baidu Netcom pledged all of their equity interests in Baidu Netcom to Baidu Online to guarantee their obligations under the loan agreement and Baidu Netcom’s performance of its obligations under the exclusive technology consulting and services agreement. If Baidu Netcom or its shareholders breach their respective contractual obligations, Baidu Online, as the pledgee, will be entitled to certain rights, including the right to sell the pledged equity interests. The shareholders of Baidu Netcom agreed not to dispose of the pledged equity interests or take any actions that would prejudice Baidu Online’s interest. The equity pledge agreement will expire two years after expiration of the term or the fulfillment by Baidu Netcom and its shareholders of their respective obligations under the exclusive technology consulting and services agreement and the loan agreement.

Each of the equity pledge agreements amongst Baidu Online and the respective shareholders of Beijing Perusal and BaiduPay contains the same terms, including term period, as those described above. Each equity pledge is perfected by registration with relevant local administration for industry and commerce which is required for a property right under the PRC Property Rights Law.

Through the design of the aforementioned agreements, the shareholders of the VIEs effectively assigned their full voting rights to Baidu Online, which gives Baidu Online the power to direct the activities that most significantly impact the VIEs’ economic performance. Baidu Online obtains the ability to approve decisions made by the VIEs and the ability to acquire the equity interests in the VIEs when permitted by PRC law. Baidu Online is obligated to absorb a majority of the expected losses from the VIEs’ activities through providing unlimited financial support to the VIEs and is entitled to receive a majority of residual returns from the VIEs through the exclusive technology consulting and service fees. As a result of these contractual agreements, Baidu Online is determined to be the primary beneficiary of the VIEs. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIEs through these contractual agreements, and the Company consolidates the VIEs through Baidu Online.

There are similar agreements entered into by Primary Beneficiaries other than Baidu Online with their VIEs and the respective shareholders, which resulted in a parent-subsidiary relationship between the Company and these VIEs.

In the opinion of the Company’s legal counsel, (i) the ownership structure of the Company and its VIEs is in compliance with existing PRC laws and regulations; (ii) the contractual arrangements with the VIEs and their shareholders are valid, binding and enforceable, and will not result in any violation of PRC laws or regulations currently in effect; and (iii) the Group’s business operations are in compliance with existing PRC laws and regulations in all material respects.

However, uncertainties in the PRC legal system could cause the Company’s current ownership structure to be found in violation of any existing and/or future PRC laws or regulations and could limit the Company’s ability, through the Primary Beneficiaries, to enforce its rights under these contractual arrangements. Furthermore, shareholders of the VIEs may have interests that are different than those of the Company, which could potentially increase the risk that they would seek to act contrary to the terms of the aforementioned agreements.

In addition, if the current structure or any of the contractual arrangements were found to be in violation of any existing or future PRC law, the Company may be subject to penalties, which may include but not be limited to, the cancellation or revocation of the Company’s business and operating licenses, being required

to restructure the Company’s operations or discontinue the Company’s operating activities. The imposition of any of these or other penalties may result in a material and adverse effect on the Company’s ability to conduct its operations.

1. | ORGANIZATION, CONSOLIDATION AND PRESENTATION OF FINANCIAL STATEMENTS (CONTINUED)

Equity Pledge Agreement (Continued)

As of December 31, 2013, there was no pledge or collateralization of the VIEs’ assets. The amount of the net assets of the VIEs, which are restricted under PRC laws and regulations (Note 16), was RMB46.91 million (US$7.75 million) as of December 31, 2013. The creditors of the VIEs’ third-party liabilities did not have recourse to the general credit of the Primary Beneficiaries in normal course of business. The Company did not provide or intend to provide financial or other supports not previously contractually required during the years presented.

Basis of Accounting

The consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”).

Principles of Consolidation

The consolidated financial statements include the financial statements of the Company, its wholly-owned and majority-owned subsidiaries, VIEs and subsidiaries of the VIEs. All inter-company transactions and balances between the Company, its wholly-owned and majority-owned subsidiaries, VIEs and subsidiaries of the VIEs are eliminated upon consolidation. The Company has included the results of operations of acquired businesses from the respective dates of acquisition.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Management evaluates estimates, including those related to the accounts receivable allowances, fair values of options to purchase the Company’s or its subsidiaries’ ordinary shares, fair values of certain equity investments, the purchase price allocation and fair value of noncontrolling interests with respect to business combinations, and deferred tax valuation allowance, among others. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.

Comparative Information

Certain items in the consolidated financial statements have been reclassified to conform to the current year’s presentation to facilitate comparison.

Currency Translation for Financial Statements Presentation

Translations of amounts from RMB into US$ for the convenience of the reader have been calculated at the exchange rate of RMB6.0537 per US$1.00 on December 31, 2013, the last business day in fiscal year 2013, as published on the website of the United States Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted into U.S. dollars at such rate.

2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Foreign Currency

The Company’s functional currency is the US$. The Company’s wholly-owned and majority-owned subsidiaries, VIEs and subsidiaries of the VIEs determine their functional currencies based on the criteria of ASC topic 830 (“ASC 830”), Foreign Currency Matters. The Company uses the RMB as its reporting currency. The Company uses the average exchange rate for the year and the exchange rate at the balance sheet date to translate its operating results and financial position, respectively. Any translation gains (losses) are recorded in other comprehensive income (loss). Transactions denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are included in earnings as a component of other income.

Segment Reporting

In accordance with ASC topic 280 (“ASC 280”), Segment Reporting: Overall, the Company’s chief operating decision makers rely upon consolidated results of operations when making decisions about allocating resources and assessing performance of the Company; hence, the Company has only one single operating segment. The Company does not distinguish between markets or segments for the purpose of internal reporting.

Business Combinations

The Company accounts for its business combinations using the purchase method of accounting in accordance with ASC topic 805 (“ASC 805”): Business Combinations. The purchase method of accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Company acquired, based on their estimated fair values. The consideration transferred of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings.

In a business combination achieved in stages, the Company remeasures its previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the re-measurement gain or loss, if any, is recognized in earnings.

The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period.

Cash and Cash Equivalents

Cash and cash equivalents

Cash and cash equivalents are stated at cost, which approximates fair value, and primarily consist of cash and investments in interest bearing demand deposit accounts, time deposits, highly liquid investments and money market funds. All time deposits, money market funds and other highly liquid investments with original maturities of three months or less from the date of purchase are classified as cash equivalents.

Restricted cash

Restricted cash mainly consists of the cash reserved in escrow accounts for the remaining payments in relation to certain business acquisitions and compensation for postcombination services by the selling shareholders, as well as the cash balances deposited by users or customers of the Group that were held for designated purposes.

The cash balances deposited by users or customers of the Group for certain businesses are considered restricted because they cannot be used for the operations of the Group or any other purposes not designated by the users or customers. The deposited balance is included in the Group’s bank account until being used for the designated purpose or withdrawn by the users or customers.

Accounts Receivable

Accounts receivable are recognized and carried at original invoiced amount less an allowance for any potential uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer probable. Bad debts are written off as incurred. The Company generally does not require collateral from its customers.

The Company maintains allowances for doubtful accounts for estimated losses resulting from the failure of customers to make payments on time. The Company reviews the accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, the customer’s payment history, its current credit-worthiness and current economic trends.

Receivables from Online Payment Agencies

Receivables from online payment agencies are cash due from the third-party online payment service providers for clearing transactions. The cash was paid or deposited by customers or users through these online payment agencies for services provided by the Company. The Company carefully considers and monitors the credit worthiness of the third-party payment service providers used. An allowance for doubtful accounts is recorded in the period in which a loss is determined to be probable. Receivable balances are written off after all collection efforts have been exhausted. As of December 31, 2012 and 2013, no allowance for doubtful accounts was provided for the receivable.

Investments

Short-term investments

All highly liquid investments with original maturities of greater than three months, but less than 12 months, are classified as short-term investments. Investments that are expected to be realized in cash during the next 12 months are also included in short-term investments. The Company accounts for short-term investments in accordance with ASC subtopic 320 (“ASC 320”), Investments - Debt and Equity Securities. The Company classifies the short-term investments in debt and equity securities as “held-to-maturity”, “trading” or “available-for-sale”, whose classification determines the respective accounting methods stipulated by ASC 320. Dividend and interest income, including amortization of the premium and discount arising at acquisition, for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short-term investments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized.

The securities that the Company has positive intent and ability to hold to maturity are classified as held-to-maturity securities and stated at amortized cost. For individual securities classified as held-to-maturity securities, the Company evaluates whether a decline in fair value below the amortized cost basis is other-than-temporary in accordance with the Company’s policy and ASC 320. When the Company intends to sell an impaired debt security or it is more-likely-than-not that it will be required to sell prior to recovery of its amortized cost basis, an other-than-temporary impairment is deemed to have occurred. In these instances, the other-than-temporary impairment loss is recognized in earnings equal to the entire excess of the debt security’s amortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. When the Company does not intend to sell an impaired debt security and it is more-likely-than-not that it will not be required to sell prior to recovery of its amortized cost basis, the Company must determine whether or not it will recover its amortized cost basis. If the Company concludes that it will not, an other-than-temporary impairment exists and that portion of the credit loss is recognized in earnings, while the portion of loss related to all other factors is recognized in other comprehensive income.

The securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities. Unrealized holding gains and losses for trading securities are included in earnings.

Investments not classified as trading or as held-to-maturity are classified as available-for-sale securities. Available-for-sale investment is reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss). Realized gains or losses are included in earnings during the period in which the gain or loss is realized. An impairment loss on the available-for-sale securities would be recognized in the consolidated statements of comprehensive income when the decline in value is determined to be other-than-temporary.

Long-term investments

The Company’s long-term investments consist of cost method investments, equity method investments and held-to-maturity investments with original and remaining maturities of greater than 12 months.

In accordance with ASC subtopic 325-20 (“ASC 325-20”), Investments-Other: Cost Method Investments, for investments in an investee over which the Company does not have significant influence and which do not have readily determinable fair value, the Company carries the investment at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings that exceed the Company’s share of

earnings since its investment. Management regularly evaluates the impairment of the cost method investments based on performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of investment.

Investments in entities in which the Company can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC topic 323 (“ASC 323”), Investments-Equity Method and Joint Ventures. Under the equity method, the Company initially records its investment at cost and the difference between the cost of the equity investee and the fair value of the underlying equity in the net assets of the equity investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The Company subsequently adjusts the carrying amount of the investment to recognize the Company’s proportionate share of each equity investee’s net income or loss into earnings after the date of investment. The Company will discontinue applying the equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero. Under the conditions that the Company is not required to advance additional funds to an investee and the equity-method investment in ordinary shares is reduced to zero, if further investments are made that have a higher liquidation preference than ordinary shares, the Company would recognize the loss based on its percentage of the investment with the same liquidation preference, and the loss would be applied to those investments of a lower liquidation preference first before being further applied to the investments of a higher liquidation preference. The Company evaluates the equity method investments for impairment under ASC 323. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary.

Long-term held-to-maturity investments are measured in the same manner as short-term held-to-maturity investments.

Fair Value Measurements of Financial Instruments

Financial instruments are in the form of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, amounts due to and due from related parties, long-term investments, accounts payable and accrued liabilities, customer advances and deposits, derivative instruments, notes payable and long-term loans. The carrying amounts of these financial instruments, except for long-term cost method investments, long-term equity method investments, long-term held-to-maturity investments, derivative instruments, notes payable and long-term loans, approximate their fair values because of their generally short maturities. The derivative instruments were adjusted to fair value at each reporting date. The carrying amounts of long-term held-to-maturity investments and long-term loans approximate their fair values due to the fact that the related interest rates approximate rates currently offered by financial institutions for similar debt instruments of comparable maturities. Based on the quoted market price as of December 31, 2013, the fair value of the notes payable was RMB14.80 billion (US$2.44 billion) (Note 21).

Research, Development and Computer Software

Capitalization of software developed for internal use

The Company has capitalized certain internal use software development costs in accordance with ASC subtopic 350-40 (“ASC 350-40”), Intangibles-Goodwill and Other: Internal-Use Software, amounting to RMB44.26 million, RMB38.13 million and RMB2.68 million (US$0.44 million) for the years ended December 31, 2011, 2012 and 2013, respectively. The Company capitalizes certain costs relating to software acquired, developed, or modified solely to meet the Company’s internal requirements and for which there are no substantive plans to market the software. These costs mainly include payroll and payroll-related costs for employees who are directly associated with and who devote time to the internal-use software projects during the application development stage. Capitalized internal-use software costs are included in “intangible assets, net”. The amortization expense for capitalized software costs amounted to RMB7.51 million, RMB19.72 million and RMB31.65 million (US$5.23 million) for the years ended December 31, 2011, 2012 and 2013, respectively. The unamortized amount of capitalized internal use software development costs was RMB70.45 million and RMB41.48 million (US$6.85 million) as of December 31, 2012 and 2013, respectively.

Research and development expenses

Research and development expenses consist primarily of personnel-related costs. The Company has expensed substantially all development costs incurred in the research and development of new products and new functionality added to the existing products except for certain internal use software development costs.

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis over the shorter of the estimated useful lives of the assets or the term of the related lease, as follows:

Office building |  | - 45 years
Office building related facility, machinery and equipment |  | - 15 years
Computer equipment |  | - 3 or 5 years
Office equipment |  | - 3 or 5 years
Vehicles |  | - 5 years
Leasehold improvements |  | - over the shorter of lease terms or estimated useful lives of the assets

Fixed assets have no estimated residual value except for the office building and its related facility, machinery and equipment, which have an estimated residual value of 4% of the cost.

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in earnings.

All direct and indirect costs that are related to the construction of fixed assets and incurred before the assets are ready for their intended use are capitalized as construction in progress. Construction in progress is transferred to specific fixed assets items and depreciation of these assets commences when they are ready for their intended use.

Fixed Assets (Continued)

Interest costs are capitalized if they are incurred during the acquisition, construction or production of a qualifying asset and such costs could have been avoided if expenditures for the assets have not been made. Capitalization of interest costs commences when the activities to prepare the asset are in progress and expenditures and borrowing costs are being incurred. Interest costs are capitalized until the assets are ready for their intended use. Interest costs capitalized for the years ended December 31, 2011, 2012 and 2013 were insignificant.

Goodwill and Intangible Assets

Goodwill

The Company assesses goodwill for impairment in accordance with ASC subtopic 350-20 (“ASC 350-20”), Intangibles - Goodwill and Other: Goodwill, which requires that goodwill be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20.

Subsequent to the acquisitions in 2011 and thereafter, there were segment managers who regularly review operating results of certain acquired entities and the rest of the Group, which constitute three separate reporting units as of December 31, 2012 and 2013.

Goodwill was tested for impairment in the annual impairment tests on December 31 in each year using the two-step process required by ASC 350-20. First, the Company compared the carrying amount of the reporting unit to the fair value of the reporting unit based on either quoted market prices of the ordinary shares or estimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Company must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss. In accordance with Accounting Standards Update (“ASU”) No. 2011-08 (“ASU 2011-08”), Testing Goodwill for Impairment, the Company has the option to first assess qualitative factors to determine whether it is necessary to perform the two-step test. If the Company believes, as a result of the qualitative assessment, that it is more-like-than-not that the fair value of the reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required.

In 2013, the Company elected to assess goodwill for impairment at two reporting units, representing acquired entities, using the two-step process. The fair value of the two reporting units exceeded their respective carrying amount, and therefore goodwill related to these two reporting units were not impaired and the Company was not required to perform further testing. The Company performed a qualitative assessment for the remaining reporting unit. Based on the requirements of ASU 2011-08, the Company evaluated all relevant factors, weighed all factors in their totality and concluded that it was not more-likely-than-not the fair value was less than the carrying amount of the third reporting unit, and further impairment testing on goodwill was unnecessary as of December 31, 2013.

Goodwill and Intangible Assets (Continued)

Intangible assets

Intangible assets with finite lives are carried at cost less accumulated amortization. Land use rights are amortized using a straight-line method over the shorter of their estimated economic lives or the terms of related land use right contracts. Licensed copyrights of video contents are amortized using an accelerated method, which results in a pattern of amortization that is more reflective of the consumption of the assets. All other intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives.

Intangible assets have weighted average economic lives from the date of purchase as follows:

Land use rights |  | - 50 years
Customer relationships |  | - 5.5 years
Software |  | - 4.3 years
Trademarks |  | - 10.0 years
User list |  | - 3.4 years
Licensed copyrights of video contents |  | - 2.7 years
Others |  | - 5.9 years

Intangible assets with an indefinite useful life are not amortized and are tested for impairment annually or more frequently if events or changes in circumstances indicate that they might be impaired in accordance with ASC subtopic 350-30 (“ASC 350-30”), Intangibles-Goodwill and Other: General Intangibles Other than Goodwill.

Impairment of Long-Lived Assets Other Than Goodwill

The Company evaluates long-lived assets, such as fixed assets and purchased or internally developed intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with ASC topic 360 (“ASC 360”), Property, Plant and Equipment. When such events occur, the Company assesses the recoverability of the assets group based on the undiscounted future cash flow the assets group is expected to generate and recognizes an impairment loss when estimated undiscounted future cash flow expected to result from the use of the assets group plus net proceeds expected from disposition of the assets group, if any, is less than the carrying value of the assets group. If the Company identifies an impairment, the Company reduces the carrying amount of the assets group to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values. The Company uses estimates and judgments in its impairment tests and if different estimates or judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets.

Revenue Recognition

The Company recognizes revenue based on the following principles:

(1) Click-through based online marketing services

The Company’s auction-based pay-for-performance (“P4P”) platform enables a customer to place its website link and related description on the Company’s search result list on the website which could be accessed through personal computer or mobile devices. Customers make bids on keywords based on how much they are willing to pay for each click to their listings in the search results listed on the Company’s website and the relevance between the keywords and the customer’s businesses. Internet users’ search of the keyword will trigger the display of the listings. The ranking of the customer’s listing depends on both the bidding price and the listing’s relevance to the keyword searched. Customer pays the Company only when a user clicks on one of its website links. Other than the auction-based P4P platform, the Company has certain vertical platforms from which it generates revenue through pre-determined prices per click. Revenue is recognized when a user clicks on one of the customer-sponsored website links, as there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection is reasonably assured, as prescribed by ASC topic 605 (“ASC 605”), Revenue Recognition.

For certain customers engaged through direct sales, the Company may provide certain value-added consultative support services to help its customers to better utilize its online marketing system. Fees for such services are recognized as revenue on a pro-rata basis over the contracted service period.

(2) Other performance-based online marketing services

To the extent the Company provides online marketing services based on performance criteria other than click-throughs, such as the number of telephone calls brought to its customers, the number of users registered with its customers, the number of minimum click-throughs, the number of successful reservation of hotels or issuance of air tickets, the number of downloads (and user registration) of mobile applications, the number of incremental end users and the total incremental revenue generated, revenue is recognized when the specified performance criteria are met together with satisfaction of other applicable revenue recognition criteria as prescribed by ASC 605.

(3) Time-based online advertising services

For time-based online advertising services such as text links, banners, icons or other forms of graphical advertisements in the websites or mobile applications, the Company recognizes revenue in accordance with ASC 605, on a pro-rata basis over the contractual term commencing on the date the customer’s advertisement is displayed on a specified webpage or mobile applications. For certain time-based contractual agreements, the Company may also provide certain performance guarantees, in which cases revenue is recognized at the later of the completion of the time commitment or performance guarantee.

(4) Online game services and other revenue sharing services

The Company operates online game platforms on which registered users can access games provided by third-party game developers. The Company also operates mobile platforms on which users can access smartphone related products such as themes, wallpapers and e-books developed and owned by third-party content providers. The rights and obligations of each party to the arrangement indicate that the Company is

acting as an agent whereas the game developer or the content provider is the principal as a result of being the primary obligor in the arrangement in accordance with subtopic ASC 605-45 (“ASC 605-45”), Revenue Recognition: Principal Agent Consideration. The Company recognizes the shared revenue from these online promotional services, on a net basis, based on the ratios pre-determined with the online game developers or content providers when all the revenue recognition criteria set forth in ASC 605 are met, which is generally when the user purchases virtual currencies issued by the game developers or purchases contents developed by the content providers.

(5) Online marketing services involving Baidu Union

Baidu Union is the program through which the Company expands distribution of its customers’ sponsored links or advertisements by leveraging traffic of the Baidu Union members’ internet properties. The Company makes payments to Baidu Union members for acquisition of traffic. The Company recognizes gross revenue for the amount of fees it receives from its customers. Payments made to Baidu Union members are included in cost of revenues as traffic acquisition costs.

(6) Group buying services

The Company generates revenue from group buying services as a marketing agent by offering goods and services provided by third-party merchant partners at a discount through the website or mobile application that connects merchants to consumers. The Company presents revenue on a net basis, representing the amount billed to registered users less the amount paid to merchants, in accordance with ASC 605-45. The Company acts as an agent rather than as the principal in the delivery of the products or services as it does not assume the risks and rewards of ownership of products nor is it responsible for the actual fulfillment of services. Both of these are the responsibilities of the merchants. The Company recognizes revenue when all of the criteria prescribed in ASC 605 are met, which is generally when the merchants provide the services or when the products are delivered to the customers, or upon the end of the redemption period. Since the Company’s paying users have the ability to request for full refund before redemption for the products or services offered by the merchants, the underlying sale from which the Company earns the related commission revenue as an agent is not culminated until its paying users actually redeem.

(7) Barter transactions

The Company engages in barter transactions from time to time and in such situations follows the guidance set forth in ASC topic 845 (“ASC 845”), Nonmonetary Transactions. While nonmonetary transactions are generally recorded at fair value, if such value is not determinable within reasonable limits, the transaction is recognized based on the carrying value of the product or services provided. The Company also engages in certain advertising barter transactions and follows the guidance set forth in ASC subtopic 605-20 (“ASC 605-20”), Revenue Recognition: Services. The advertising barter transactions generally are recorded at fair value. If the fair value of the advertising surrendered in the barter transaction is not determinable within required limits, the barter transaction is recorded based on the carrying amount of the advertising surrendered, which likely to be zero. The amount of revenues recognized for barter transactions was insignificant for each of the years presented.

Revenue Recognition (Continued)

In certain instances, the Company is granted equity instruments in exchange for services and accounts for such transactions in accordance with ASC 845, Nonmonetary Transactions. With respect to the measurement date, in accordance with ASC subtopic 505-50 (“ASC 505-50”), Equity: Equity-based Payments to Non-Employees, the Company measures the fair value of those equity instruments for revenue recognition purposes as of the earlier of either of the following dates:

| • |  | The date the parties come to a mutual understanding of the terms of the equity-based compensation arrangement and a commitment for performance by the Company to earn the equity instruments is reached;

| • |  | The date at which the Company’s performance necessary to earn the equity instruments is completed.

If, as of the measurement date, the fair value of the equity instruments received is not determinable within reasonable limits, the transaction is recognized based on the fair value of the services provided. If the fair value of both the equity instruments received and the services provided cannot be determined, no revenue is recognized for the services provided and the equity instrument received is recorded at zero carrying value. The amount of revenues recognized for such transactions was insignificant for each of the years presented.

(8) Other revenue recognition related policies

In accordance with ASC subtopic 605-25 (“ASC 605-25”), Multiple-Deliverable Revenue Arrangements, for deliverables in multiple-element arrangements, the total consideration of the arrangements is allocated based on their relative selling price, with the selling price of each deliverable determined using vendor-specific objective evidence (“VSOE”) of selling price, third-party evidence (“TPE”) of selling price, or management’s best estimate of the selling price (“BESP”). The Company considers all reasonably available information in determining the BESP, including both market and entity-specific factors.

The Company delivers some of its online marketing services to end customers through engaging third-party distributors. In this context, the Company may provide cash incentives to distributors. The cash incentives are accounted for as reduction of revenue in accordance with ASC subtopic 605-50 (“ASC 605-50”), Revenue Recognition: Customer Payments and Incentives.

The Company provides sales incentives to customers to entitle customers to receive reductions in the price of the online marketing services by meeting certain cumulative consumption requirements. The Company accounts for these award credits granted to members in conjunction with a current sale of products or services as a multiple-element arrangement by analogizing to ASC 605-25. The consideration allocated to the award credits, as deferred revenue is based on an assumption that the customer will purchase the minimum amount of future service necessary to obtain the maximum award credits available. The deferred revenue is recognized as revenue proportionately as the future services are delivered to the customer or when the award credits expire.

Cash received in advance from customers is recorded as customer advances and deposits. The unused cash balances remaining in the customers’ accounts are included as liabilities of the Company. Deferred revenue is recorded when services are provided before the other revenue recognition criteria set forth in ASC 605 are fulfilled.

2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Cost of Revenues

Cost of revenues consists primarily of sales taxes (including business tax and output value-added tax) and surcharges, traffic acquisition costs, bandwidth costs, depreciation, content costs, payroll and related costs of operations.

The Company incurs sales taxes and surcharges in connection with the provision of online marketing services, technical and consultative service fees charged by its subsidiaries to VIEs and other taxable services in the PRC. In accordance with ASC 605-45, the Company includes the sales tax and surcharges incurred on its online marketing revenues in cost of revenues. The sales tax and surcharges in cost of revenues for the years ended December 31, 2011, 2012 and 2013 were RMB1.02 billion, RMB1.57 billion and RMB2.33 billion (US$384.82 million), respectively. Traffic acquisition costs represent the amounts paid or payable to Baidu Union members who direct search queries to the Company’s websites or distribute the Company’s customers’ paid links through their properties. These payments are primarily based on revenue sharing arrangements under which the Company pays its Baidu Union members and other business partners a percentage of the fees it earns from its online marketing customers.

Advertising Expenses

Advertising expenses, primarily advertisements through various forms of media, are included in “Selling, general and administrative expense” in the consolidated statements of comprehensive income and are expensed when incurred. Advertising expenses for the years ended December 31, 2011, 2012 and 2013 were RMB157.10 million, RMB326.83 million and RMB191.61 million (US$31.65 million), respectively.

Government Subsidies

Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. There are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. For the government subsidies with non-operating nature and with no further conditions to be met, the amounts are recorded as non-operating income in “Other income, net” when received; whereas for the government subsidies with certain operating conditions, the amounts are recorded as liabilities when received and will be recorded as operating income when the conditions are met.

Leases

Leases have been classified as either capital or operating leases. Leases that transfer substantially all the benefits and risks incidental to the ownership of assets are accounted for as capital leases as if there was an acquisition of an asset and incurrence of an obligation at the inception of the lease. All other leases are accounted for as operating leases wherein rental payments are expensed as incurred.

Income Taxes

The Company recognizes income taxes under the liability method. Deferred income taxes are recognized for differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the years in which the differences are expected to reverse. The Company records a valuation

Income Taxes (Continued)

allowance against the amount of deferred tax assets that it determines is not more-likely-than-not to be realized. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date.

The Company applies the provisions of ASC topic 740 (“ASC 740”), Income Taxes, in accounting for uncertainty in income taxes. ASC 740 clarified the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The Company has elected to classify interest and penalties related to an uncertain tax position (if and when required) as part of income tax expense in the consolidated statements of comprehensive income. As of and for the years ended December 31, 2011, 2012 and 2013, the amounts of unrecognized tax benefits as well as interest and penalties associated with uncertainty in income taxes were insignificant.

Share-based Compensation

The Company accounts for share-based compensation in accordance with ASC topic 718 (“ASC 718”), Compensation-Stock Compensation. The Company has elected to recognize share-based compensation using the straight-line method for all share-based awards issued with no performance conditions. For awards with performance conditions, compensation cost is recognized on an accelerated basis if it is probable that the performance condition will be achieved.

Forfeitures have been estimated based on historical experience and are periodically reviewed. Cancellation of an award accompanied by the concurrent grant of a replacement award is accounted for as a modification of the terms of the cancelled award (“modification awards”). The compensation costs associated with the modification awards are recognized if either the original vesting condition or the new vesting condition has been achieved. Such compensation costs will not be less than the grant-date fair value of the original award. The incremental compensation cost is measured as the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation date. Therefore, in relation to the modification awards, the Company recognizes share-based compensation over the vesting periods of the new options, which comprises, (i) the amortization of the incremental portion of share-based compensation over the remaining vesting term and (ii) any unrecognized compensation cost of original award, using either the original term or the new term, whichever results in higher expenses for each reporting period.

The Company accounts for share awards issued to non-employees in accordance with the provisions of ASC 505-50. The Company uses the Black-Scholes-Merton option pricing model method to measure the value of options granted to non-employees at each vesting date to determine the appropriate charge to share-based compensation. ASC 718 requires share-based compensation to be presented in the same manner as cash compensation rather than as a separate line item.

Earnings Per Share (“EPS”)

The Company computes earnings per Class A and Class B ordinary shares in accordance with ASC topic 260 (“ASC 260”), Earnings Per Share, using the two-class method. Under the provisions of ASC 260, basic net income per share is computed using the weighted average number of ordinary shares outstanding during the period except that it does not include unvested ordinary shares subject to repurchase or cancellation. Diluted net income per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities have been

excluded from the computation of diluted net income per share if their inclusion is anti-dilutive. Potential ordinary shares consist of the incremental ordinary shares issuable upon the exercise of stock options, restricted shares subject to forfeiture, and contracts that may be settled in the Company’s stock or cash. The dilutive effect of outstanding stock options and restricted shares is reflected in diluted earnings per share by application of the treasury stock method. Securities issued by a subsidiary that enable their holders to obtain the subsidiary’s ordinary shares are included in the consolidated earnings per share computations based on the Company’s holding of the subsidiary’s securities. The computation of the diluted net income per share of Class A ordinary shares assumes the conversion of Class B ordinary shares, while the diluted net income per share of Class B ordinary shares does not assume the conversion of those shares.

The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are identical, except with respect to voting. As a result, and in accordance with ASC 260, the undistributed earnings for each year are allocated based on the contractual participation rights of the Class A and Class B ordinary shares as if the earnings for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B ordinary shares is assumed in the computation of the diluted net income per share of Class A ordinary shares, the undistributed earnings are equal to net income for that computation.

The Company elects to account for the entire periodic adjustment for accretion of the redeemable noncontrolling interests in the calculation of income available to ordinary shareholders of the Company used in the earnings per share calculation.

For the purposes of calculating the Company’s basic and diluted earnings per Class A and Class B ordinary shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the date of exercise of such options.

Contingencies

The Company records accruals for certain of its outstanding legal proceedings or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, on a quarterly basis, developments in legal proceedings or claims that could affect the amount of any accrual, as well as any developments that would make a loss contingency both probable and reasonably estimable. The Company discloses the amount of the accrual if it is material.

When a loss contingency is not both probable and estimable, the Company does not record an accrued liability but discloses the nature and the amount of the claim, if material. However, if the loss (or an additional loss in excess of the accrual) is at least reasonably possible, then the Company discloses an estimate of the loss or range of loss, if such estimate can be made and material, or states that such estimate is immaterial if it can be estimated but immaterial, or discloses that an estimate cannot be made. The assessments of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often involve complex judgments about future events. Management is often unable to estimate the loss or a range of loss, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including eventual loss, fine, penalty or business impact, if any.

Concentration of Risks

Concentration of credit risk

Financial instruments that potentially subject the Company to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, short-term investments, accounts receivable and amounts due from related parties. As of December 31, 2013, the Company has RMB38.69 billion (US$6.39 billion) in cash and cash equivalents, restricted cash and short-term investments, 89.16% and 10.84% of which are held by financial institutions in the PRC and international financial institutions outside of the PRC, respectively, without a single bank or financial institution holding a substantial amount of the balances. The Company’s total cash and cash equivalents, restricted cash and short-term investments held at Bank of China and J.P. Morgan, the largest percentage held at one single PRC financial institution and international financial institution, represent 22.97% and 3.36% of the Company’s total cash and cash equivalents, restricted cash and short-term investments as of December 31, 2013, respectively.

PRC state-owned banks, such as Bank of China, are subject to a series of risk control regulatory standards, and PRC bank regulatory authorities are empowered to take over the operation and management when any of those faces a material credit crisis. The Company does not foresee substantial credit risk with respect to cash and cash equivalents, restricted cash and short-term investments held at the PRC state-owned banks. Meanwhile, China does not have an official deposit insurance program, nor does it have an agency similar to what was The Federal Deposit Insurance Corporation (FDIC) in the U.S. In the event of bankruptcy of one of the financial institutions in which the Company has deposits or investments, it may be unlikely to claim its deposits or investments back in full. The Company selected reputable international financial institutions with high rating rates to place its foreign currencies. The Company regularly monitors the rating of the international financial institutions in case of any defaults. There has been no recent history of default in relation to these financial institutions.

Accounts receivable are typically unsecured and derived from revenue earned from customers and agents in China, which are exposed to credit risk. The risk is mitigated by credit evaluations the Company performs on its customers and its ongoing monitoring process of outstanding balances. The Company maintains reserves for estimated credit losses and these losses have generally been within its expectations.

Amounts due from related parties are typically unsecured, interest-free and repayable on demand. In evaluating the collectability of the amounts due from related parties balance, the Company considers many factors, including the related parties’ repayment history and their credit-worthiness. An allowance for doubtful accounts is made when collection of the full amount is no longer probable.

Business and economic risks

The Company participates in a dynamic high technology industry and believes that changes in any of the following areas could have a material adverse effect on the Company’s future financial position, results of operations or cash flows: changes in the overall demand for services and products; changes in business offerings; competitive pressures due to new entrants; advances and new trends in new technologies and industry standards; changes in bandwidth suppliers; changes in certain strategic relationships or customer relationships; regulatory considerations; copyright regulations; and risks associated with the Company’s ability to attract and retain employees necessary to support its growth.

No customer or any Baidu Union member generated greater than 10% of total revenues in any of the periods presented.

2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Concentration of Risks (Continued)

The Company’s operations could be adversely affected by significant political, economic and social uncertainties in the PRC.

Currency convertibility risk

Substantially all of the Company’s businesses are transacted in RMB, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through the Bank of China or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.

Foreign currency exchange rate risk

The functional currency and the reporting currency of the Company are the US$ and RMB, respectively. The Company’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents, short-term investments and notes payable denominated in the US$. On June 19, 2010, the People’s Bank of China announced the end of the RMB’s de facto peg to the US$, a policy which was instituted in late 2008 in the face of the global financial crisis, to further reform the RMB exchange rate regime and to enhance the RMB’s exchange rate flexibility. The exchange rate floating bands will remain the same as previously announced in the inter-bank foreign exchange market. The depreciation of the US$ against RMB was approximately 2.83% in 2013. Any significant revaluation of RMB may materially and adversely affect the Company’s cash flows, revenues, earnings and financial position, and the value of, and any dividends payable on, the ADS in US$. As a result, an appreciation of RMB against the US$ would result in foreign currency translation losses when translating the net assets of the Company from the US$ into RMB.

Derivative Instruments

ASC topic 815 (“ASC 815”), Derivatives and Hedging, requires all contracts which meet the definition of a derivative to be recognized on the balance sheet as either assets or liabilities and recorded at fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in earnings or in other comprehensive income depending on the use of the derivative and whether it qualifies for hedge accounting. Changes in fair values of derivatives not qualified as hedges are reported in earnings. The estimated fair values of derivative instruments are determined at discrete points in time based on the relevant market information. These estimates are calculated with reference to the market rates using industry standard valuation techniques. The fair value of the derivative instruments held by the Company was insignificant for all years presented.

Business Combinations in 2013:

Acquisition of 91 Wireless

On October 1, 2013, the Company acquired 100% of the outstanding ordinary shares of 91 Wireless Websoft Limited (“91 Wireless”), a leading Chinese mobile application marketplaces and mobile games operator, with which the Company expects to enhance its ability and market share in mobile online marketing business. The results of 91 Wireless’s operations have been included in the Company’s consolidated financial statements since October 1, 2013.

Among the total purchase consideration, US$1.83 billion was paid upon the consummation of the acquisition and US$10.00 million was deposited in an escrow account in case of any breach of the representations and warranties made upon the acquisition or indemnifiable loss incurred, if any, such as claims, damages or penalties. The escrowed amount will be released and transferred to the original shareholders after a period of 18 months from the acquisition date. The remaining of the consideration represents the settlement of the pre-existing relationships between the Company and 91 Wireless, which was insignificant.

The Company has completed the valuations necessary to assess the fair values of the tangible and intangible assets acquired and liabilities assumed, resulting from which the amount of goodwill was determined and recognized as of the acquisition date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of October 1, 2013, the date of acquisition:

|  | RMB |  |  | US$ |
|  | (In thousands) |
Purchase consideration |  |  | 11,196,235 |  |  |  | 1,849,486 |
Net assets acquired, excluding intangible assets and the related deferred tax liabilities |  |  | 483,341 |  |  |  | 79,842 |
Intangible assets, net |  |  | 1,146,300 |  |  |  | 189,355 |
Deferred tax liabilities, noncurrent |  |  | (278,346 | ) |  |  | (45,979 | )
Goodwill |  |  | 9,844,940 |  |  |  | 1,626,268 |

The Company has evaluated the fair value of the acquired intangible assets and has assigned the following value and estimated useful life to those intangible assets: a user list of RMB359.80 million (US$59.43 million) with a useful life of 3.3 years, customer relationships of RMB302.00 million (US$49.89 million) with a useful life of 3.3 years, trademarks of RMB289.00 million (US$47.74 million) with a useful life of 10.0 years, software of RMB114.10 million (US$18.85 million) with a useful life of 5.3 years, and developer relationships of RMB81.4 million (US$13.45 million) with a useful life of 2.3 years.

Goodwill, which is not tax deductible, is primarily attributable to synergies expected to be achieved from the acquisition. The synergies mainly come from the enhancement of the Company’s leading position on the rapidly emerging mobile area, especially the distribution of applications for mobile devices, which could better promote the Company’s products, reduce costs and expenses by sharing the infrastructure, distribution channel and common research and development results, and further foster an ecosystem with better user experience for mobile products, stronger user loyalty, and greater value for both customers and developers that enhance the Company’s monetization ability on the emerging mobile markets.

The Company recognized RMB16.70 million (US$2.76 million) of acquisition related costs which were included in general and administrative expenses in the year ended December 31, 2013.

Business Combinations in 2013: (Continued)

The Company is unable to ascertain the acquisition date fair value of certain assets acquired and liabilities assumed and the associated adjustments necessary to complete the purchase price allocation disclosures for one of the acquisitions. As a result, the accounting for the business combination is incomplete as of the date when the financial statements are issued. The financial statements reflected provisional amounts used to record the transaction. As information subsequently becomes available, such provisional amounts shall be retrospectively adjusted.

Either the results of operations since the respective acquisition dates or pro forma results of operations of these acquirees were not presented because the effects of these business combinations, individually and in the aggregate, were not material to the Company’s consolidated results of operations.

The valuations used in the purchase price allocation for the acquisitions in 2013 were determined by the Company with the assistance of an independent third party valuation firm. The valuation reports considered generally accepted valuation methodologies such as the income, market and cost approaches. As the acquirees are all private companies, the fair value estimates of noncontrolling interests are based on significant inputs that market participants would consider, which mainly include (a) discount rates, (b) a projected terminal values based on EBITDA, (c) financial multiples of companies in the same industries and (d) adjustments for lack of control or lack of marketability.

Business Combinations in 2012:

During the year ended December 31, 2012, the Company completed several business combinations, which the Company expects to complement its existing business and achieve significant synergies. The acquired entities were considered immaterial, both individually and in aggregate. The results of the acquired entities’ operations have been included in the Company’s consolidated financial statements since their respective dates of acquisition.

The Company has completed the valuations necessary to assess the fair values of the tangible and intangible assets acquired and liabilities assumed and the fair value of noncontrolling interests, resulting from which the amount of goodwill was determined and recognized as of the respective acquisition dates.

Business Combinations in 2012: (Continued)

The aggregate purchase price allocation included the acquisitions of Qiyi.com Inc (“Qiyi”) and certain other acquirees. Qiyi and one of the other acquirees were equity method investees of the Company prior to their respective acquisitions. The Company applied the equity method of accounting by recognizing its share of the profit or loss in these equity method investees up to their respective dates of acquisition.

The valuations used in the purchase price allocation described above were determined by the Company with the assistance of independent third party valuation firms. The valuation reports considered generally accepted valuation methodologies such as the income, market and cost approaches. As the acquirees are all private companies, the fair value estimates of pre-existing equity method investments or noncontrolling interests are based on significant inputs that market participants would consider, which mainly include (a) discount rates, (b) a projected terminal values based on EBITDA, (c) financial multiples of companies in the same industries and (d) adjustments for lack of control or lack of marketability.

Either the results of operations since the acquisition dates or pro forma results of operations of the acquirees were not presented because the effects of these business combinations, individually and in the aggregate, were not material to the Company’s consolidated results of operations.

Business Combinations in 2011:

Acquisition of Qunar

On July 20, 2011, the Company acquired 62.01% of the equity interest of Qunar Cayman Islands Limited (“Qunar”), a leading provider of travel search products in China, with which the Company expects to achieve significant synergies. The results of Qunar’s operations have been included in the Company’s consolidated financial statements since July 20, 2011.

The total purchase consideration of US$300.28 million was paid in cash. The following table summarizes the estimated fair values of the assets acquired, liabilities assumed and the noncontrolling interests as of July 20, 2011, the date of acquisition:

|  | RMB |

4. | INVESTMENTS

Short-term Investments

As of December 31, 2013, all of the held-to-maturity investments were time deposits in commercial banks with a maturity of less than one year. The available-for-sale investments are debt securities with a maturity of less than one year purchased from commercial banks and other financial institutions as well as equity securities in a listed entity.

11. | NOTES PAYABLE

On November 28, 2012, the Company issued and sold publicly two tranches of unsecured senior notes: (i) an aggregate principal amount of US$750.00 million which will mature on November 28, 2017 (the “2017 Notes”), and (ii) an aggregate principal amount of US$750.00 million which will mature on November 28, 2022 (the “2022 Notes”). On August 6, 2013, the Company issued and sold publicly another tranche of unsecured senior notes with an aggregate principal amount of US$1.00 billion which will mature on August 6, 2018 (the “2018 Notes”). The 2017 Notes, 2018 Notes and 2022 Notes are collectively referred to as the “Notes”.

The 2017 Notes bear interest at the rate of 2.25% per annum and the 2022 Notes bear interest at the rate of 3.50% per annum. Interests are payable semi-annually in arrears on and of each year, beginning on May 28, 2013. The 2018 Notes bear interest at the rate of 3.25% per annum. Interests are payable semi-annually in arrears on and of each year, beginning on February 6, 2014. At maturity, the Notes are payable at their principal amount plus accrued and unpaid interest thereon.

The net proceeds from the Notes, after deducting offering expenses, were RMB9.30 billion and RMB6.07 billion (US$1.00 billion) for the years ended December 31, 2012 and 2013, respectively, which will be used for general corporate purposes.

The Notes do not contain any financial covenants or other significant restrictions. In addition, the Notes are unsecured and rank lower than any secured obligation of the Group and have the same liquidation priority as any other unsecured liabilities of the Group, but senior to those expressly subordinated obligations, if any. The Company may, at its discretion, redeem all or any portion of the Notes at any time, at the principal amount plus any unpaid interest. As of December 31, 2013, the Company does not intend to redeem any portion of the Notes prior to the stated maturity dates. The Company has the obligation to redeem the Notes if a change in control occurs as defined in the indenture of the Notes.

The Notes were issued at a discount amounting to RMB20.47 million (US$3.38 million). The issuance costs of RMB79.85 million (US$13.19 million) were capitalized in other non-current assets on the consolidated balance sheets. Both the discount and the issuance costs are amortized as interest expense using the effective interest rate method through the maturity dates of the Notes. The effective interest rate was 2.36%, 3.39% and 3.59% for the 2017 Notes, the 2018 Notes and the 2022 Notes, respectively.

12. | INCOME TAXES

The Company is incorporated in the Cayman Islands and conducts its primary business operations through the subsidiaries and VIEs in the PRC. It also has intermediate holding companies in the British Virgin Islands (“BVI”) and Hong Kong. Under the current laws of the Cayman Islands and BVI, the Company is not subject to tax on income or capital gains. Additionally, upon payments of dividends by the Company to its shareholders, no Cayman Islands and BVI withholding tax will be imposed. Under the Hong Kong tax laws, subsidiaries in Hong Kong are exempted from income tax on their foreign-derived income and there are no withholding taxes in Hong Kong on remittance of dividends.

China

Under the Enterprise Income Tax (“EIT”) Law, which has been effective since January 1, 2008, domestic enterprises and Foreign Investment Enterprises (the “FIE”) are subject to a unified 25% enterprise income tax rate, except for certain entities that are entitled to tax holidays. Tax holidays mainly include preferential EIT rate for the PRC subsidiaries and VIEs which were recognized as a qualified “High and New Technology Enterprise” (“HNTE”) or “Key Software Enterprise” (“KSE”).

The HNTE certificate is effective for a period of 3 years, during which the entity is entitled to a preferential tax rate of 15%. The KSE certificate is effective for a period of 2 years, during which the entity is entitled to a preferential tax rate of 10%. Baidu Online obtained the KSE certificate and the related tax holiday will expire on January 1, 2015; certain other PRC subsidiaries and VIEs, including Baidu Netcom, obtained the HNTE certificate which will expire on January 1, 2014, 2015 and 2016. An entity could re-apply for the HNTE or KSE certificate when the prior certificate expires. Historically, all of the Company’s subsidiaries and VIEs successfully re-applied for the certificates when the prior ones expired.

A certificate for the current year might be obtained in the following year as a result of the stringent inspection and approval process by the governmental authorities. The Company would record an income tax reversal in the year when the certificate is obtained for the over-paid or over-accrued provisional tax in connection with the grant of a more favorable tax rate for the prior year.

Under the current EIT Law, dividends paid by an FIE to any of its foreign non-resident enterprise investors are subject to a 10% withholding tax. Thus, the dividends, if and when payable by the Company’s PRC subsidiaries to their offshore parent entities, would be subject to 10% withholding tax. A lower tax rate will be applied if such foreign non-resident enterprise investor’s jurisdiction of incorporation has signed a tax

treaty or arrangement for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income with China. There is such a tax arrangement between PRC and Hong Kong. Thus, the dividends, if and when payable by the Company’s PRC subsidiaries to the offshore parent entities located in Hong Kong, would be subject to 5% withholding tax rather than statutory rate of 10% provided that the offshore entities located in Hong Kong meet the requirements stipulated by relevant PRC tax regulations. Furthermore, pursuant to the applicable circular and interpretations of the current EIT Law, dividends from earnings created prior to 2008 but distributed after 2008 are not subject to withholding income tax.

Moreover, the current EIT Law treats enterprises established outside of China with “effective management and control” located in China as PRC resident enterprises for tax purposes. The term “effective management and control” is generally defined as exercising overall management and control over the business, personnel, accounting, properties, etc. of an enterprise. The Company, if considered a PRC resident enterprise for tax purposes, would be subject to the PRC Enterprise Income Tax at the rate of 25% on its worldwide income for the period after January 1, 2008. As of December 31, 2013, the Company has not accrued for PRC tax on such basis. The Company will continue to monitor its tax status.

Japan

Baidu Japan Inc. (“Baidu Japan”) with a paid-in capital in excess of JPY100.00 million is subject to national income tax of 30%. Baidu Japan is also subject to inhabitant tax, assessed by both prefectures and municipalities. Inhabitant tax is computed as a percentage of national income tax. The per capita tax is based on the Company’s capitalization and the number of employees. In addition, Baidu Japan is subject to a corporate enterprise tax on a pro forma basis based on the amount of taxable profit subject to the corporate tax, added-value components, (e.g., labor costs, net interest and rental payments, income/loss for current year) and a capital component. Baidu Japan has been in a cumulative loss position since its inception.

The Company had minimal operations in jurisdictions other than the PRC. Income (loss) before income taxes consists of:

As of December 31, 2013, the Company had net operating losses of approximately RMB2.22 billion (US$365.89 million) deriving from entities in the PRC, Hong Kong and Japan, which can be carried forward after certain reconciliation per tax regulation to offset future net profit for income tax purposes. The Japan net operating loss will expire beginning January 1, 2015; the PRC net operating loss will expire beginning January 1, 2017; and the Hong Kong net operating loss can be carried forward without an expiration date.

For those entities that were in an accumulated loss position, the Company does not believe there exists sufficient objective positive evidence that the recoverability of their net deferred tax assets is more-likely-than-not to be realized. Consequently, the Company has provided full valuation allowances on the related net deferred tax assets.

The Company has evaluated its income tax uncertainty under ASC 740. ASC 740 clarifies the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The Company has elected to classify interest and penalties related to an uncertain tax position, if and when required, as part of income tax expense in the consolidated statements of comprehensive income. As of and for the years ended December 31, 2012 and 2013, there was no significant tax uncertainty impact on the Company’s financial position and result of operations.

12. | INCOME TAXES (CONTINUED)

The Company did not provide for deferred income taxes and foreign withholding taxes on the undistributed earnings of foreign subsidiaries as of December 31, 2012 on the basis of its intent to permanently reinvest foreign subsidiaries’ earnings. As of December 31, 2013, the Company accrued withholding tax of RMB580.72 million for the potential remittance of earnings from the PRC subsidiaries to their offshore parent companies in the form of dividend distribution, because the Company believes that the underlying dividends will be distributed in the future considering future merger and acquisition activities. The Company believes that it has the ability and intent to indefinitely reinvest the remaining undistributed earnings as of December 31, 2013. If these foreign earnings were to be repatriated in the future, the related tax liability may be reduced by any foreign income taxes previously paid on these earnings. Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. In the case of its VIEs, undistributed earnings were insignificant as of each of the balance sheet dates.

In general, the PRC and Japanese tax authorities have up to five and seven years, respectively, to conduct examinations of the Company’s tax filings. Accordingly, the PRC subsidiaries’ tax years 2009 through 2013 and the Japanese subsidiary’s tax years 2007 through 2013 remain open to examination by the respective taxing jurisdictions.

13. | EMPLOYEE DEFINED CONTRIBUTION PLAN

Full time employees of the Group in the PRC participate in a government mandated multi-employer defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the Group make contributions to the government for these benefits based on certain percentages of the employees’ salaries. The Company has no legal obligation for the benefits beyond the contributions. The total amounts for such employee benefits, which were expensed as incurred, were RMB381.74 million, RMB631.25 million and RMB1.05 billion (US$172.80 million) for the years ended December 31, 2011, 2012 and 2013, respectively.

14. | COMMITMENTS AND CONTINGENCIES

Capital Commitments

The Company’s capital commitments relate primarily to commitments in connection with the expansion and improvement of its network infrastructure and its plan to acquire or build additional office buildings and cloud computing based data centers.

Accordingly, the Company evaluates its guarantees to determine whether (a) the guarantee is specifically excluded from the scope of ASC 460, (b) the guarantee is subject to ASC 460 disclosure requirements only, but not subject to the initial recognition and measurement provisions, or (c) the guarantee is required to be recorded in the financial statements at fair value.

Guarantees (Continued)

The corporate by-laws require that the Company indemnify its officers and directors, as well as those who act as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to the Company. In addition, the Company has entered into separate indemnification agreements with each director and each executive officer of the Company that provide for indemnification of these directors and officers under similar circumstances and under additional circumstances. The indemnification obligations are more fully described in the by-laws and the indemnification agreements. The Company purchases standard directors and officers insurance to cover claims or a portion of the claims made against its directors and officers. Since a maximum obligation is not explicitly stated in the Company’s by-laws or in the indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated.

Historically, the Company has not been required to make payments related to these obligations, and the fair value for these obligations is zero on the consolidated balance sheets as of December 31, 2012 and 2013.

Litigation

The Group was involved in certain cases pending in various PRC and U.S. courts and arbitration as of December 31, 2013. These cases include copyright infringement cases, unfair competition cases, and defamation cases, among others. Adverse results in these lawsuits may include awards of damages and may also result in, or even compel, a change in the Company’s business practices, which could result in a loss of revenue or otherwise harm the business of the Company.

For many proceedings, the Company is currently unable to estimate the reasonably possible loss or a range of reasonably possible losses as the proceedings are in the early stages, and/or there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. As a result, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, which includes eventual loss, fine, penalty or business impact, if any, and therefore, an estimate for the reasonably possible loss or a range of reasonably possible losses cannot be made. However, the Company believes that such matters, individually and in the aggregate, when finally resolved, are not reasonably likely to have a material adverse effect on the Company’s consolidated results of operations, financial position and cash flows. With respect to the limited number of proceedings for which the Company was able to estimate the reasonably possible losses or the range of reasonably possible losses, such estimated loss amounts were insignificant.

16. | SHAREHOLDERS’ EQUITY

Ordinary Shares

Upon completion of the Company’s initial public offering (“IPO”) in August 2005, 16,648,877 Class B Ordinary shares were issued upon conversion of all convertible preferred shares. In addition, immediately following the closing of the IPO, the Memorandum and Articles of Association were amended and restated such that the authorized share capital consisted of 870,400,000 ordinary shares at a par value of US$0.00005 per share, of which 825,000,000 shares were designated as Class A ordinary shares, 35,400,000 as Class B ordinary shares, and 10,000,000 shares designated as preferred shares. The rights of the holders of Class A and Class B ordinary shares are identical, except with respect to voting and conversion rights. Each share of Class A ordinary shares is entitled to one vote per share and is not convertible into Class B ordinary shares under any circumstances. Each share of Class B ordinary shares is entitled to ten votes per share and is convertible into one Class A ordinary share at any time by the holder thereof. Upon any transfer of Class B ordinary shares by the holder thereof to any person or entity that is not an affiliate of such holder, such Class B ordinary shares would be automatically converted into an equal number of Class A ordinary shares. There were 1,332, 40,000 and 225,079 Class B ordinary shares transferred to Class A ordinary shares in the years ended December 31, 2011, 2012 and 2013, respectively.

Each of the Company’s PRC subsidiaries is required to allocate at least 10% of its after-tax profits to a general reserve fund until such fund has reached 50% of its respective registered capital. Appropriations to the enterprise expansion fund and staff welfare and bonus funds are at the discretion of the Company’s subsidiaries.

In accordance with the China Company Laws, the Company’s VIEs must make appropriations from their after-tax profits as reported in their PRC statutory accounts to non-distributable reserve funds, namely a statutory surplus fund, a statutory public welfare fund and a discretionary surplus fund. Each of the Company’s VIEs is required to allocate at least 10% of its after-tax profits to the statutory surplus fund until such fund has reached 50% of its respective registered capital.

General reserve and statutory surplus funds are restricted to set-off against losses, expansion of production and operation and increasing registered capital of the respective company. Staff welfare and bonus fund and statutory public welfare funds are restricted to capital expenditures for the collective welfare of employees. The reserves are not allowed to be transferred to the Company in terms of cash dividends, loans or advances, nor are they allowed for distribution except under liquidation.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2011, 2012 and 2013

17. | EARNINGS PER SHARE (“EPS”) (CONTINUED)

The Company did not include certain stock options and restricted shares in the computation of diluted earnings per share for the years ended December 31, 2011, 2012 and 2013 because those stock options and restricted shares were anti-dilutive for earnings per share for the respective years.

18. | SHARE-BASED AWARDS PLAN

Baidu, Inc.

Incentive compensation plans

In December 2008, the Company adopted a share incentive plan (the “2008 Plan”), which provides for the granting of share incentives, including incentive share option (“ISO”), restricted shares and any other form of award pursuant to the 2008 Plan, to members of the board, employees and consultants of the Company. However, the Company may grant ISOs only to its employees. The Company has reserved 3,428,777 ordinary shares for issuance under the 2008 Plan, which will expire in the year 2018. The vesting schedule, time and condition to exercise options will be determined by the compensation committee. The term of the options may not exceed ten years from the date of the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of the Company’s share capital.

Under the 2008 Plan, the exercise price per share subject to an option may be amended or adjusted at the discretion of the compensation committee, the determination of which would be final, binding and conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment of the exercise prices would be effective without the approval of the Company’s shareholders or the approval of the affected grantees. If the Company grants an ISO to an employee who, at the time of that grant, owns shares representing more than 10% of the voting power of all classes of the Company’s share capital, the exercise price cannot be less than 110% of the fair market value of the Company’s ordinary shares on the date of that grant.

Starting from February 15, 2006, the Company has granted restricted Class A ordinary shares of the Company (“Restricted Shares”). Terms for the Restricted Shares are the same as share options except that Restricted Shares do not require exercise and have a two to four years vesting term.

Share options

The following table summarizes the option activity for the year ended December 31, 2013:

|  | Number of shares |  |  | Weighted average exercise price (US$) |  |  | Weighted average remaining contractual life (Years) |  |  | Aggregate intrinsic value (US$ in thousands) |

18. | SHARE-BASED AWARDS PLAN (CONTINUED)

Baidu, Inc. (Continued)

The aggregate intrinsic value in the table above represents the difference between the Company’s closing stock price on the last trading day in 2013 and the exercise price.

Total intrinsic value of options exercised for the years ended December 31, 2011, 2012 and 2013 was RMB275.86 million, RMB200.91 million and RMB114.21 million (US$18.87 million), respectively.

As of December 31, 2013, there was RMB357.31 million (US$59.02 million) unrecognized share-based compensation cost related to share options. That deferred cost is expected to be recognized over a weighted-average vesting period of 2.90 years. To the extent the actual forfeiture rate is different from the original estimate, actual share-based compensation costs related to these awards may be different from expectation.

The fair value of each option award was estimated on the date of grant using the Black-Scholes-Merton valuation model. The volatility assumption was estimated based on implied volatility and historical volatility of the Company’s share price applying the guidance provided by ASC 718. The Company begins to estimate the volatility assumption solely based on its historical information since year 2009. Assumptions about the expected term were based on the vesting and contractual terms and employee demographics. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The following table presents the assumptions used to estimate the fair values of the share options granted in the years presented:

|  | 2011 |  |  | 2012 |  |  | 2013 |
Risk-free interest rate |  |  | 0.31%~1.03% |  |  |  | 0.35%~0.43% |  |  |  | 0.40%~1.35% |
Dividend yield |  |  | — |  |  |  | — |  |  |  | — |
Expected volatility range |  |  | 48.20%~61.58% |  |  |  | 43.60%~44.72% |  |  |  | 42.33%~44.17% |
Weighted average expected volatility |  |  | 58.27% |  |  |  | 43.75% |  |  |  | 43.33% |
Expected life (in years) |  |  | 2.66~3.00 |  |  |  | 2.67~3.08 |  |  |  | 3.08~4.57 |

In addition, the Company recognizes share-based compensation expense net of an estimated forfeiture rate and therefore only recognizes compensation cost for those shares expected to vest over the service period of the award. The estimation of the forfeiture rate is based primarily upon historical experience of employee turnover. To the extent the Company revises this estimate in the future, the share-based payments could be materially impacted in the year of revision, as well as in the following years.

The exercise price of options granted during the years 2011, 2012 and 2013 equaled the market price of the ordinary shares on the grant date. The weighted-average grant-date fair value of options granted during the years 2011, 2012, and 2013 was US$432.68, US$323.00, and US$419.80, respectively.

Restricted shares

Restricted shares activity for the year ended December 31, 2013 was as follows:

|  | Number of shares |  |  | Weighted average grant date fair value (US$) |
Restricted shares |  |  |  |  |  |  |  |
Unvested, December 31, 2012 |  |  | 114,816 |  |  |  | 1,164.10 |
Granted |  |  | 87,123 |  |  |  | 1,137.00 |

Unvested, December 31, 2013 |  |  | 146,510 |  |  |  | 1,151.40 |

The total fair value of the restricted shares vested during the years ended December 31, 2011, 2012 and 2013 was RMB198.77 million, RMB128.70 million, RMB247.24 million (US$40.84 million), respectively.

As of December 31, 2013, there was RMB652.94 million (US$107.86 million) unrecognized share-based compensation cost related to restricted shares. That deferred cost will be recognized over a weighted-average vesting period of 2.83 years. To the extent the actual forfeiture rate is different from the original estimate, actual share-based compensation costs related to these awards may be different from expectation.

Subsidiaries

Certain subsidiaries also have equity incentive plans granting share-based awards. Total share-based compensation expenses recognized and unrecognized were insignificant, both individually and in aggregate, for all years presented.

The following table summarizes the total compensation cost recognized by the Group:

21. | FAIR VALUE MEASUREMENT

ASC topic 820 (“ASC 820”), Fair Value Measurements and Disclosures, establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets

Level 2 - Include other inputs that are directly or indirectly observable in the marketplace

Level 3 - Unobservable inputs which are supported by little or no market activity

ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.

Assets and Liabilities Measured or Disclosed at Fair Value

In accordance with ASC 820, the Company measures available-for-sale investments at fair value on a recurring basis. The fair values of the Company’s available-for-sale debt investments as measured and held-to-maturity investments as disclosed are determined based on the discounted cash flow model using the discount curve of market interest rates. The fair value of the Company’s available-for-sale equity investments in the equity securities of a publicly listed company is measured using quoted market prices.

Assets and Liabilities Measured or Disclosed at Fair Value (Continued)

The Company measures certain financial assets, including equity method investments and cost method investments, at fair value on a nonrecurring basis only if an impairment charge were to be recognized. The Company’s non-financial assets, such as intangible assets, goodwill and fixed assets, would be measured at fair value only if they were determined to be impaired on an other-than-temporary basis.

The fair value of the long-term notes payable is disclosed using quoted market prices.
