Item 3.  Key Information.

A. Selected Consolidated Financial and Statistical Data

The selected consolidated statements of income data for the years ended December 31, 2015, 2016 and 2017 and the selected consolidated balance sheet data as of December 31, 2016 and 2017 are derived from our audited consolidated financial statements appearing elsewhere in this Annual Report. The selected consolidated balance sheet data as of December 31, 2013, 2014 and 2015 and consolidated statements of income data for the years ended December 31, 2013 and 2014 are derived from our audited consolidated financial statements that are not included in this Annual Report, after adjustment for the retrospective adoption of Accounting Standard Updates 2015‑03 and 2015‑17.

Ruble amounts have been translated into U.S. dollars at a rate of RUB 57.6002 to $1.00, the official exchange rate quoted as of December 31, 2017 by the Central Bank of the Russian Federation. Such U.S. dollar amounts are not necessarily indicative of the amounts of U.S. dollars that could actually have been purchased upon exchange of Russian rubles at the dates indicated, and have been provided solely for the convenience of the reader. On March 21, 2018, the exchange rate was RUB 57.7033 to $1.00. See “Risk Factors—Emerging markets, such as Russia, are generally subject to greater financial, economic, legal and political risks than more developed markets. Such risks may have a material adverse effect on our business, financial condition and results of operations.”

(2) A major component of other income/(loss), net is foreign exchange gains and losses generally resulting from changes in the value of the U.S. dollar compared with the Russian ruble. Because the functional currency of our operating subsidiaries in Russia is the Russian ruble, changes in the ruble value of these subsidiaries’ monetary assets and liabilities that are denominated in other currencies (primarily U.S. dollar‑denominated cash, cash equivalents and term deposits maintained in Russia) due to exchange rate fluctuations are recognized as foreign exchange gains or losses in our statement of income. For example, in 2017, other loss, net includes RUB 1,784 million of foreign exchange losses arising from the appreciation of the Russian ruble compared to the U.S. dollar in that year. In 2016, other loss, net included a RUB 3,834 million loss arising from the significant appreciation of the Russian ruble compared to the U.S. dollar in that year. Although the U.S. dollar value of our U.S. dollar

4

denominated cash, cash equivalents and term deposits are not impacted by these currency fluctuations, they result in upward and downward revaluations of the ruble equivalent of these U.S. dollar denominated monetary assets.

Exchange Rate Information

Our business is primarily conducted in Russia and almost all of our revenues are denominated in Russian rubles. We have presented our most recent annual results of operations in U.S. dollars for the convenience of the reader. Unless otherwise noted, all conversions from RUB to U.S. dollars and from U.S. dollars to RUB in this Annual Report were made at a rate of RUB 57.6002 to $1.00, the official exchange rate quoted by the Central Bank of the Russian Federation as of December 31, 2017. On March 21, 2018, the exchange rate was RUB  57.7033 to $1.00. Such U.S. dollar amounts are not necessarily indicative of the amounts of U.S. dollars that could actually have been purchased upon exchange of Russian rubles at the dates indicated.

B. Risk Factors

Investing in our Class A shares involves a high degree of risk. The risks and uncertainties described below and elsewhere in this Annual Report, including in the section headed “Operating and Financial Review and Prospects”, could materially adversely affect our business. These are not the only risks that we face; additional risks and uncertainties of which we are unaware, or that we currently deem immaterial, may also become important factors that affect us. Any of these risks could adversely affect our business, financial condition and results of operations. In such case, the trading price of our Class A shares could decline.

Risks Related to the Russian Economy

Emerging markets, such as Russia, are generally subject to greater financial, economic, legal and political risks than more developed markets. Such risks may have a material adverse effect on our business, financial condition and results of operations.

Emerging markets such as Russia are subject to greater risks than more developed markets, including financial, economic, legal and political risks. Such risks or an increase in the perceived risks associated with investing in emerging economies could dampen foreign investment and adversely affect the economies of the countries in which we operate. For example, the current geopolitical situations in Ukraine and some other regions, as well as volatility in oil prices (to which the Russian economy is particularly sensitive), may continue to have deleterious macroeconomic and other effects on the regions in which we operate, including increased volatility in currency values and a weaker overall business environment. In 2014 and 2015, Russia experienced an economic downturn characterized by substantial depreciation of its currency, sharp fluctuations of interest rates, a decline in disposable income, a steep decline in the value of shares traded on its stock exchanges, a material increase in the inflation rate, and a decline in the gross domestic product. In 2016 and 2017 some of these economic trends have reversed or moderated, with the ruble strengthening, oil prices increasing, inflation rates declining significantly and the rate of decline in gross domestic product moderating. However, economic conditions continue to be unstable and future changes may have negative effect on our business. In addition, international sanctions have been imposed on identified parties and business sectors in Russia in connection with the geopolitical situation in Ukraine, as described below, which may adversely affect us or business conditions in our markets. 

In connection with the current economic situation, in 2017 the Russian ruble appreciated against the US dollar by 5%, after depreciating materially during the course of 2015 and appreciating materially by 20% in 2016. Although our revenues and expenses, including our personnel expenses, are both primarily denominated in Russian rubles we may have to increase our personnel expenses in order to better compete with other companies that denominate their personnel expenses in currencies which appreciate in relation to the Russian ruble. Also, the majority of our rent expenses, including the lease for our Moscow headquarters, are denominated in U.S. dollars, and a major portion of our capital expenditures, primarily for servers and networking equipment, although payable in rubles, is for imported goods and therefore can be materially affected by changes in the value of the ruble. In addition, our expenses related to the development of our business internationally, as well as for acquisitions, are often denominated in other currencies, including U.S. dollars and Euros. If the Russian ruble were to experience a prolonged and significant decline in value against foreign currencies, we could face material foreign currency exchange exposure, which may materially adversely affect our business, financial condition and results of operations. See “Operating and Financial Review and Prospects—Quantitative and Qualitative Disclosures About Market Risk”

Should the Russian economy experience a contraction or slower growth in the future, it may adversely affect our results of operations in certain periods. In addition, these conditions may from time to time to depress or encourage volatility in our share price and in equity markets in general.

The adoption and maintenance of international embargo, economic or other sanctions, in particular with respect to the conflict in Ukraine, may have a material adverse effect on our business, financial condition and results of operations.

Significant uncertainty exists surrounding the current geopolitical situation in Ukraine. The United States, the European Union and certain other countries have imposed economic sanctions on certain Russian government officials, private individuals and Russian companies, as well as “sectoral” sanctions affecting specified types of transactions with named participants in certain industries, including named Russian financial institutions, and sanctions that prohibit most

6

commercial activities of U.S. and EU persons in Crimea and Sevastopol. In the course of 2017 these sanctions were successively prolonged and extended. There is significant uncertainty regarding the extent or timing of any potential further economic or trade sanctions, or the ultimate outcome of the Ukrainian crisis. Political and economic sanctions may affect the ability or willingness of our international customers to operate in Russia, which could negatively impact our revenue and profitability. Sanctions could also impede our ability to effectively manage our legal entities and operations in and outside of Russia. We are domiciled in the Netherlands, while our wholly owned principal operating subsidiary is organized under the laws of the Russian Federation, and several of our other subsidiaries are incorporated in other countries that have imposed economic sanctions on the Russian Federation. Although neither our parent company nor our principal operating subsidiary or other subsidiaries are targets of U.S. or EU sanctions, our business has been adversely affected from time to time by the impact of sanctions on the broader economy in Russia. In addition, Yandex.Money, our joint venture with Sberbank, is subject to U.S. sectoral sanctions.

Since May 2017, Yandex LLC and Yandex.Ukraine LLC, both subsidiaries of Yandex N.V., have been subject to sanctions in Ukraine, which have blocked Ukrainian users from accessing our services and websites. Sanctions have been imposed for three years with the possibility of extension and ban all trade operations and require blocking of all assets, including bank accounts. The Ukrainian Security Service (SBU) also conducted searches at Yandex offices in Kiev and Odessa. Such actions led to the shutdown of Yandex’s commercial operations in Ukraine. 

In January 2018, pursuant to the Countering America’s Adversaries through Sanctions Act of 2017, the U.S. administration presented the U.S. Congress with a report on senior Russian political figures, “oligarchs” and “parastatal” entities.  Our founder, executive director and substantial shareholder, Arkady Volozh, is one of nearly 100 persons included in one part of the so called “Kremlin List”, on the basis of his reported net worth and Herman Gref, a member of our Board of Directors and the CEO and Chairman of Sberbank, the holder of our priority share, was included on the “List of Senior Political Figures.”  Although we are not aware of any intention on the part of the U.S. government to impose sanctions on Mr. Volozh, Mr. Gref or other persons named on this list, if Mr. Volozh or Mr. Gref were to become a target of sanctions, it could have material adverse effect on our business. 

In December 2017, we entered into a binding agreement with Sberbank to form a joint venture in respect of our Yandex.Market business unit. Although Sberbank and a number of its subsidiaries are subject to “sectoral” sanctions, we believe that the pending joint venture is not within the scope of these prohibitions.  Going forward, however, applicable sanctions could impose limitations on our ability to provide additional financing to this joint venture. 

We could also be subject to a number of potential sanctions-related risks in the future.  First, the sanctions rules, or the authoritative interpretation of current rules by the relevant authorities, could change at any time.  In particular, OFAC (or other regulators) could:

· add additional parties to the sectoral sanctions list,

· designate the parties with whom we have significant business relationships as “specially designated nationals”, meaning that all dealings with them by U.S. and/or EU persons would be prohibited; or 

· expand current or new sanctions to cover entities that are less than 50% owned by a listed party, which could adversely affect our new Yandex.Market joint venture. 

We are not aware of any proposals in this regard, but any such decisions would likely reflect the evolving geopolitical and U.S. domestic climate over time. In addition, the applicable sanctions requirements are interpreted broadly by the relevant authorities. In addition, many U.S. and EU parties typically take a very conservative view of compliance matters, given the ambiguities of some of these rules and the approach taken by the regulators. Some parties, in particular U.S. and EU financial institutions, have adopted internal compliance policies that are more restrictive than are strictly required by the applicable rules and have, for example, declined to engage in any dealings with parties on the sectoral sanctions list (including dealings that are not prohibited by the rules applicable to such parties) or with entities closely affiliated with such entities (even if such affiliated entities are not themselves a target of sanctions). 

Although we act in strict compliance with applicable laws and regulations and adhere to the principles of political neutrality in all countries where we operate, further political, civil or military conflicts in the region may result in a general lack of confidence among international investors in the region’s economic and political stability and in

7

Russian investments generally. Along with potential official government sanctions on Russia, U.S. and foreign investors may be pressured to reduce or withdraw their investments in Russia. Such circumstances may result in trading volatility, reduced liquidity and significant declines in the price of listed securities of companies with significant operations in Russia, including our Class A shares.

Risks Related to Our Business and Industry

We face significant competition from major global and Russian companies, including Google and Mail.ru, which could negatively affect our business, financial condition and results of operations.

We face strong competition in various aspects of our business from global and Russian companies that provide internet services and content, including search services. Currently, we consider our principal competitors in our core business to be Google and Mail.ru. 

Of the large global internet companies, we consider Google to be our principal competitor in the market for desktop and mobile internet search, and for performance-based advertising, online advertising network revenues, advertising intermediary services, distribution arrangements and other services. According to Yandex Radar, Google’s share of the Russian search market, based on search traffic generated, was 39.6% for the full year 2017 and 37.1% in 2016, compared with our market share of 55.1% in 2017 and 56.0% in 2016. Google conducts extensive online and offline advertising campaigns in Russia. In recent years, Google has aggressively marketed its products and services, including its Chrome browser in which its search engine is the default search function, its mobile application, as well as its maps and navigation products, leading to increased competition.

With Android, its popular mobile platform, Google exerts significant influence over the increasingly important market for mobile and location-based search and advertising. Pursuant to a settlement between FAS and Google reached in April 2017, Google is prohibited from arrangements prohibiting pre-installation of rival applications and is required to provide a choice to users in selecting their default search engine.  Nevertheless, it is difficult to anticipate the long-term effects of such changes on our market shares in Android.  Furthermore, we expect that Google will continue to use its brand recognition and global financial and engineering resources to compete aggressively with us. In addition to Google, we also face competition, albeit less intense, from the Russian and international businesses of Microsoft and Yahoo!

On the domestic side, our principal competitor is Mail.ru Group. Although we power paid search on Mail.ru Group properties and monetize a number of Mail.ru Group properties through our Yandex Advertising Network, we also compete with Mail.ru Group for online advertising budgets, allocated between social networks and search, as well as in food delivery services (through Mail.ru Group’s recent acquisition of Delivery Club and our recent acquisition of FoodFox.)  In addition, Mail.ru Group offers a wide range of internet services, the most popular Russian web mail service, and other services that are comparable to ours. Mail.ru’s search market share was 4.1% and 3.4% in 2016 and 2017, respectively.  

Although we have partnerships with a number of social networking sites and serve ads on some of these sites, we also view them as increasingly significant competitors. In light of their large audiences and the significant amount of information they can access and analyze regarding their users’ needs, interests and habits, we believe that they may be able to offer highly targeted advertising that could create increased competition for us. The popularity of such sites may also reflect a growing shift in the way in which people find information, get answers and buy products, which may create additional competition to attract users.

In addition, our business units, which include Taxi, Classifieds and E-commerce, face significant competition in their respective business areas. 

Our Taxi business, a joint venture with Uber which we completed in February 2018, faces competition from Gett, as well as a variety of other taxi and ride-sharing operators and dispatch services. In addition, although Yandex.Taxi and Uber operate as a joint venture in Russia and neighboring countries, our Taxi business may also compete with Uber in jurisdictions outside the scope of our joint venture territory.

Our Classifieds business faces competition from a range of online and offline classified services, including Avito, CIAN (in real estate), and Drom.ru (in automobile sales); and our E-commerce business faces competition from online

8

retailers and marketplaces, including AliExpress and Avito, as well as offline retailers.

We cannot guarantee that we will be able to continue to compete effectively with current and future companies that may have greater ability to attract and retain users, greater name recognition, more personnel and greater financial and other resources. If our competitors are successful in providing similar or better search results or other services compared with those we offer, we could experience a significant decline in user traffic or other business. Any such decline could negatively affect our business, financial condition and results of operations.

The competition to capture market share on mobile devices is intense, and if we are not successful in achieving substantial reach among users and monetizing search and other services on mobile devices, our business, financial condition and results of operations could be adversely affected.

Users are increasingly accessing the internet through mobile and other devices rather than desktop and laptop personal computers, including through smartphones, wearable devices, and handheld computers such as tablets, as well as through video game consoles and television set-top devices. Such devices have different characteristics than desktop and laptop personal computers (including screen size, operating system, user interface and use patterns). Tailoring our products and services to such devices requires particular expertise and the expenditure of significant resources. The versions of our products and services developed for these devices, including the advertising solutions we offer, may be less attractive to users, advertisers, manufacturers or distributors of devices than those offered by our competitors or than our desktop offerings. The percentage of our total search traffic that was generated from mobile devices increased from approximately 31% in the fourth quarter of 2016 to approximately 39% in the fourth quarter of 2017, while the percentage of our search revenues generated from mobile devices increased from approximately 25% to approximately 31% between those periods.

Each manufacturer or distributor of mobile or other devices may establish unique technical standards for its devices, and as a result our products and services may not work or be viewable on these devices. Some manufacturers may also elect not to include our products on their devices, or may be prohibited from doing so pursuant to their agreements with other parties. Although Google is prohibited from arrangements prohibiting pre-installation of rival applications and is required to provide a choice to users in selecting their default search engine, it is difficult to anticipate the long-term effects of such changes on our market shares in Android.  In addition, consumers are increasingly accessing content directly via applications, or “apps”, tailored to particular mobile devices or in closed social media platforms, which could affect our share of the search market over time. As new devices and platforms are continually being released, it is difficult to predict the challenges we may encounter in adapting our products and services and developing competitive new products and services. See also “—As the internet evolves, an increasing amount of online content may be held in closed social networks, mobile apps or stored in proprietary document formats, which may limit the effectiveness of our search technology, which could adversely affect our brand, business, financial condition and results of operations.”

We expect to continue to devote significant resources to the creation, support and maintenance of mobile products and services. If we are unable to attract and retain a substantial number of 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 such devices and platforms, we will fail to capture the opportunities available as consumers and advertisers transition to a dynamic, multi-screen environment. Furthermore, given the importance of distribution and application pre-installation arrangements with the most popular device manufacturers to the successful operation of our business, failure to reach such arrangements may adversely affect our business, financial condition and results of operations.

We expect the rate of growth of our revenues to be lower in the future and we may experience downward pressure on our operating margin.

We expect that our advertising revenue growth rate will decline over time as a result of a number of factors, including continuing macroeconomic challenges in Russia, challenges in maintaining our growth rate as our revenues increase to higher levels, increasing competition, changes in the nature of queries, the evolution of the overall online advertising market and the declining rate of growth in the number of internet users in Russia as overall internet penetration increases. A decline in our advertising revenue growth rate may negatively impact the rate of growth of our revenues on a consolidated basis.

Other factors which may cause our operating margin to fluctuate or decline include:

· changes in the proportion of our advertising revenues that we derive from the Yandex ad network compared

9

with our own websites. In periods in which our Yandex ad network revenues grow more rapidly than those from our own sites, our operating margin generally declines because the operating margin we realize on revenues generated from partner websites is significantly lower than the operating margin generated from our own websites, as a result of traffic acquisition costs (TAC) that we pay to our partner websites. Over several past years our partner TAC was above 50% of our online advertising network revenues. The margin we earn on revenue generated from the Yandex ad network could also decrease in the future if we are required to share with our partners a greater percentage of the advertising fees generated through their websites;

· investments we make in our business units, in particular our Yandex.Taxi business;

· increased depreciation and amortization expense related to capital expenditures for many aspects of our business, particularly the expansion of our data centers to support growth in both our current and new markets;

· relatively higher spending on advertising and marketing to further enhance our brand and promote our services in Russia, to build and expand brand awareness in other countries where we operate and to respond to competitive pressures, if these efforts do not drive revenue growth in the manner we anticipate;

· expenses in connection with the launch of new products and related advertising and marketing efforts, which may not result in the anticipated increase in revenues or market share;

· the possibility of higher fees or revenue sharing arrangements with our distribution partners that distribute our products or services or otherwise direct search queries to our website. We expect to continue to expand the number of our distribution relationships in order to increase our user base and to make it easier for our existing users to access our services;

· costs incurred in our international expansion efforts until we succeed in building the user base necessary to begin generating sufficient revenues in these markets to earn accretive operating margins there; and

· increased costs associated with the creation, support and maintenance of mobile products and services to maintain and expand our offering and competitive market position, which may not result in anticipated increases in revenues or market share.

We generate almost all of our revenues from advertising, which is cyclical and seasonal in nature, and any reduction in spending by or loss of advertisers would materially adversely affect our business, financial condition and results of operations.

In the past three years, we generated on average more than 95% of our revenues from advertising. Expenditures by advertisers tend to be cyclical, reflecting overall economic conditions and budgeting and buying patterns, and can therefore fluctuate significantly. According to AKAR, the rate of growth in online advertising expenditures was 22% in 2017 compared to the similar period of 2016, up from a growth rate of 21% in 2016 compared with 2015 and a growth rate of 15% in 2015 compared with 2014. Any decreases in online advertising spending due to economic conditions, or otherwise, could materially adversely impact our business, financial condition and results of operations.

Advertising spending and user traffic also tend to be seasonal, with internet usage, advertising expenditures and traffic historically slowing down during the months, when there are extended Russian public holidays and vacations, and increasing significantly in the fourth quarter of each year. For these reasons, comparing our results of operations on a period-to-period basis may not be meaningful, and past results should not be relied upon as an indication of future performance. Furthermore, our business becomes more diversified, thus seasonal changes may have different effect on various lines of business.

We rely on third party partners for a material portion of our revenues and for expanding our user base via distribution arrangements. Any failure to obtain or maintain such relationships on reasonable terms could have an adverse effect on our business, financial condition and results of operations.

Revenues from advertising on our ad network partner websites represented 25.5% of our online advertising

10

revenues in 2017 compared with 27.1% in 2016. We consider our ad partner network to be important for the continued growth of our business. Our agreements with our network partners, other than our agreement to power paid search results on Mail.ru, are generally terminable at any time without cause. Our competitors could offer more favorable terms to our current or potential network partners, including guaranteed minimum revenues or other more advantageous revenue-sharing arrangements, in an effort to take market share away from us. Additionally, some of our partners in the Yandex ad network, such as Mail.ru and Microsoft Bing, compete with us in one or more areas and may terminate their agreements with us in order to develop their own businesses. If our network partners decide to use a competitor’s advertising services, our revenues would decline.

Many of our key network partners operate high-profile websites, and we derive tangible and intangible benefits from this affiliation, such as increased numbers of users, extended brand awareness and greater audience reach for our advertisers. If our agreements with any of these partners are terminated or not renewed and we do not replace those agreements with comparable agreements, our business, financial condition and results of operations would be adversely affected.

The number of paid clicks and amount of revenues that we derive from our partners in the Yandex ad network depends on, among other factors, the quality of their websites and their attractiveness to users and advertisers. Although we screen new applicants, favor websites with high-quality content and stable audiences, and strive to monitor the quality of the network partner websites on an ongoing basis, these websites are operated by independent third parties that we do not control. If our network partners’ websites deteriorate in quality or otherwise fail to provide interesting and relevant content and services to their users, this may result in reduced attractiveness to their users and our advertisers, which may adversely impact our business, financial condition and results of operations.

To expand our user base and increase traffic to our sites and mobile applications, we enter into arrangements with leading software companies and device manufacturers for the distribution of our services and technology. In particular, we have agreements, on a co-marketing basis, with certain internet browsers. As new methods for accessing the internet become available, including through new digital platforms and devices, we may need to enter into new or amended distribution agreements. See also “—The competition to capture market share on mobile devices is intense, and if we are not successful in achieving substantial reach among users and monetizing search and other services on mobile devices, our business, financial condition and results of operations could be adversely affected.”

Our most significant distribution partner in 2017 was Opera, which offers mobile and desktop browsers, and where Yandex is the default search in certain search entry points. Each of our other distribution partners constitutes less than 10% of our total distribution traffic acquisition costs. If we are unable to continue our arrangements with Opera, or maintain existing or enter into comparable arrangements with new distribution partners, particularly for the distribution of our search and other services on mobile devices, this would likely have a negative effect on our search market share over time. In the future, existing and potential distribution partners may not offer or renew distribution arrangements on reasonable terms for us, or at all, which could limit our ability to maintain and expand our user base, and could have a material adverse effect on our business, financial condition and results of operations.

As the Russian internet market matures, our future expansion will increasingly depend on our ability to generate revenues from new businesses, new business models or in other markets. If we do not continue to innovate and provide services that are useful and attractive to our users, we may be unable to retain them and may become less attractive to our advertisers, which could adversely affect our business, financial condition and results of operations.

As internet usage has spread in Russia, the rate of growth in the number of internet users has been declining. Our success depends on providing search and other services that make using the internet a more useful and enjoyable experience for our users. As search technology continues to develop, our competitors may be able to offer search capabilities that are, or that are seen to be, substantially similar to, or better than, ours. As our core market matures, we will need to provide new services, further exploit non-core business models, such as our Taxi, E-commerce and Classifieds business units, or expand into new geographic markets in order to continue to grow our revenues at previously achieved levels. The cost we incur in these efforts, both in terms of product development expenses and advertising and marketing costs, can be significant.

If we are unable to continue to develop and provide our users with quality, up-to-date services, and to appropriately time the services with market opportunities, or if we are unable to maintain the quality of such services, our user base may not grow, or may decline. Further, if we are unable to attract and retain a substantial share of internet traffic

11

generated by mobile and other digital devices, or if we are slow to develop services and technologies that are compatible with such devices, our user base may not grow or may decline.

If our users move to our competitors, we will also become less attractive to advertisers and therefore to Yandex ad network partners. This could adversely affect our business, financial condition and results of operations.

Our business depends on a strong brand and our ability to license, acquire or create compelling content at reasonable costs. Failure to maintain and enhance our brand and offer compelling content would harm our ability to expand our base of users, advertisers and network partners and would materially adversely affect our business, financial condition and results of operations.

We believe that the brand identity that we have developed through the strength of our technology, our user focus and, in particular, our ability to deliver compelling content, has significantly contributed to the success of our business. We license much of our content from third parties, such as music, news items, weather reports and TV program schedules. If we are unable to maintain and build relationships with third-party content providers, this would likely result in a weakening of our brand and a loss of user traffic. In addition, we may be required to make substantial payments to third parties from whom we license or acquire such content. An increase in the prices charged to us by third-party content providers would adversely affect our business, financial condition and results of operations. In addition, many of our content licenses with third parties are non-exclusive. Accordingly, other websites and other media such as radio or television may be able to offer similar or identical content. This increases the importance of our ability to aggregate compelling content in order to differentiate Yandex from other businesses.

We also believe that maintaining and enhancing the Yandex brand, including through continued significant marketing efforts, is critical to expanding our base of users, advertisers, advertising network partners, and other business partners. As described below, several of our business units do or will operate as joint ventures.  Although we have sought to implement appropriate controls and protections, depending on specific terms of joint venture arrangements we may have more limited ability to ensure that these businesses are operated in a manner that is consistent with the broader Yandex brand.

Additionally, if we or one of our joint venture partners fail to maintain and enhance the Yandex brand, or if we incur excessive expenses in our efforts to do so, our business, financial condition and results of operations could be materially adversely affected. If other companies make available competitive content, the number of users of our services may not grow as anticipated, or may decline.

Maintaining and enhancing our brand, especially in relation to mobile services, will depend largely on our ability to continue to be a technology leader and a provider of high-quality, reliable services, which we may not continue to do successfully.

Several of our businesses operate through joint ventures with third parties, which involves risks that we do not face with respect to our core business.

Our Yandex.Taxi business now operates as a joint venture with Uber, while our Yandex.Money business operates as a joint venture with Sberbank.  We have also signed a definitive agreement to enter into a joint venture with Sberbank in respect of our Yandex.Market business. Sberbank is the holder of our priority share and Herman Gref, its chief executive officer and chairman, serves as one of our non-executive directors. Our joint venture partners have certain shareholder and contractual rights in respect of the he management of these joint ventures, and therefore we do not have sole control over the management or operations of our joint ventures. The level of control exercisable by us depends on the terms of the contractual agreements, in particular, the allocation of control among, and continued cooperation between, the participants.

We may face financial, reputational and other exposure (including regulatory censure) in the event that any of our partners fail to meet their obligations under the arrangements, encounter financial difficulty, or fail to comply with local or international regulation and standards. A temporary or permanent disruption to these arrangements, such as through significant deterioration in the reputation, financial position or other circumstances of the third party or material failure in controls, could adversely affect our results of operations.

The formation and operation of joint ventures involve significant challenges and risks, including:

12

· difficulties in integrating operations and managing the large and diverse number of personnel, products, services, technology, internal controls and financial reporting of constituent components of our joint ventures, and any unanticipated expenses relating to business integration;

· disruption of our ongoing business, distraction of our management and employees and increase of our expenses;

· departure of skilled professionals as well as the loss of established client relationships of the businesses we invest in or acquire;

· unforeseen or hidden liabilities or additional operating losses, costs and expenses that may adversely affect us following the transactions;

· potential impairment charges or write-offs due to the changes in the fair value of our business units as a result of market volatility or other reasons that we may not control which could have a material adverse effect on our financial results;

· regulatory hurdles including in relation to the anti-monopoly and competition laws;

· the risk that any of our pending or other future proposed transactions fails to close, including as a result of political and regulatory challenges and protectionist policies; and

· challenges in maintaining or further growing our business units, or achieving the expected benefits of synergies and growth opportunities in connection with these transactions.

If we fail to manage effectively the growth of our operations, our business, financial condition and results of operations could be adversely affected.

We have experienced, and continue to experience, growth in our operations, which has placed, and will continue to place, significant demands on our management and our operational and financial infrastructure.

We have carved out certain of our services into separate business units in order to facilitate the growth of those services. Management of these separate business units requires additional administrative effort, which may put strain on our management and other resources. If we do not effectively manage our growth and the operation of our business units, the quality of our services could suffer, which could adversely affect our brand, business, financial condition and results of operations.

As our user and advertiser bases expand, we will need to continue to increase our investment in technology, infrastructure, facilities and other areas of operations, in particular product development, sales and marketing. As a result of such growth, we will also need to continue to improve our operational and financial systems and managerial controls and procedures. We will have to maintain close coordination among our technical, accounting, finance, marketing and sales personnel. If the improvements are not implemented successfully, our ability to manage our growth will be impaired and we may have to make significant additional expenditures, which could harm our business, financial condition and results of operations.

We will need to make new arrangements for our Russian headquarters premises before our current lease expires in 2021, which may result in material expenses and distraction of management attention.

Our Russian headquarters are currently located in approximately 65,000 square meters of rented property in central Moscow, with leases expiring in 2021. As a consequence, once our lease expires, we will need to make alternative arrangements for our Russian headquarters, which may include negotiating a new lease for our current premises, moving to new leased premises, or purchasing or developing our own premises. If we seek to negotiate a new lease for our current or new premises, we may be unable to secure favorable terms, and may be required to agree to rent denominated in, or linked to, U.S. dollars, which would subject us to foreign exchange risk. If we decide to purchase or develop our own premises, we may incur substantial up-front expenses and may encounter challenges in managing or coordinating a development process outside our area of core competence.

13

Our corporate culture has contributed to our success, and if we cannot maintain the focus on teamwork and innovation fostered by this environment, our business, financial condition and results of operations would be adversely affected.

We believe that a critical contributor to our success has been our corporate culture, which values and fosters teamwork and innovation. As our business matures, and we are required to implement more complex organizational management structures, we may find it increasingly difficult to maintain the beneficial aspects of our corporate culture. We have carved-out a number of our services into separate business units, in order in part to maintain the “start-up spirit” and provide greater strategic and operational focus for these units. We operate or will operate several of our business units as joint ventures with other parties. In such situations our efforts in maintaining our corporate culture may not be successful, which would adversely affect our business, financial condition and results of operations. In particular, the spin‑off of certain business units or further establishing of joint ventures and partnerships may cause the loss of some of our clients, or disruption in the provision of the services that are being carved out, and may require additional attention from our management.

The loss of any of our key personnel or a failure to attract, retain and motivate qualified personnel, may have a material adverse effect on our business, financial condition and results of operations.

Our success depends in large part upon the continued service of key members of our management team and technical personnel, as well as our continued ability to attract, retain and motivate other highly qualified engineering, programming, technical, sales, customer support, financial and managerial personnel.

Although we attempt to structure employee compensation packages in a manner consistent with the evolving standards of the markets in which we operate and to provide incentives to remain with Yandex, including equity awards under our employee incentive plans, we cannot guarantee that we will be able to retain our key employees. Although we grant additional equity awards to management personnel and other key employees from time to time, employees may be more likely to leave us after their initial award fully vests. Depreciation of the market value of our shares could also make such equity awards less effective in retaining our key employees, especially for options issued above the current trading price. If any member of our senior management team or other key personnel should leave our group, our ability to successfully operate our business and execute our business strategy could be impaired. We may also have to incur significant costs in identifying, hiring, training and retaining replacements for departing employees.

The competition for software engineers and qualified personnel who are familiar with the internet industry in Russia is intense. We may encounter difficulty in hiring and/or retaining highly talented software engineers to develop and maintain our services. There is also significant competition for personnel who are knowledgeable about the accounting and legal requirements related to a NASDAQ listing, and we may encounter particular difficulty in hiring and/or retaining appropriate financial staff needed to enable us to continue to comply with the internal control requirements under the Sarbanes-Oxley Act and related regulations.

Any inability to successfully retain key employees and manage our personnel needs may have a material adverse effect on our business, financial condition and results of operations.

Growth in our operations internationally may create increased risks that could adversely affect our business, financial condition and results of operations.

We have limited experience with operations outside Russia, and in 2017 derived only approximately 7.0% of our revenues from customers outside Russia. Part of our future growth strategy is to expand our operations geographically on an opportunistic basis. Our geographic expansion efforts generally require the expenditure of significant costs in the new geography prior to achieving the market share necessary to support the commercialization of our core services, which allows us to begin generating revenues from our core services in the new geography. Our ability to manage our business and conduct our operations across a broader range of geographies will require considerable management attention and resources and is subject to a number of risks relating to international markets, including the following:

· challenges caused by distance, language and cultural differences;

· managing our relationships with local partners should we choose to adopt a joint venture approach in our international expansion efforts;

14

· credit risk and higher levels of payment fraud in certain countries;

· pressure on our operating margins as we invest to support our expansion;

· currency exchange rate fluctuations and our ability to manage our currency exposure;

· foreign exchange controls that might prevent us from repatriating cash earned in certain countries;

· legal risks, including potential of claims for infringement of intellectual property and uncertainty regarding liability for online services and content;

· adoption of new legislation and regulations, which may adversely impact our operations or may be applied in an unpredictable manner;

· potentially adverse tax consequences;

· deleterious changes in political environment;

· unexpected changes in preferences and perceptions of our users and customers; and

· higher costs and greater management time associated with doing business internationally.

In addition, compliance with complex and potentially conflicting foreign and Russian laws and regulations that apply to our international operations may increase our cost of doing business and may interfere with our ability to offer, or prevent us from offering, our services in one or more countries. These numerous laws and regulations include import and export requirements, content requirements, trade restrictions, tax laws, economic sanctions, internal and disclosure control rules, data protection, data retention, privacy and filtering requirements, labor relations laws, U.S. laws, such as the Foreign Corrupt Practices Act, and local laws prohibiting corrupt payments to governmental officials. Violations of these laws and regulations may result in fines; criminal sanctions against us, our officers, or our employees; prohibitions on the conduct of our business; and damage to our reputation. Although we have implemented policies and procedures designed to ensure compliance with these laws, we cannot assure you that our employees, contractors or agents will not violate our policies. Any such violations may result in prohibitions on our ability to offer our services in one or more countries, and may also materially adversely affect our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, and our business, financial condition and results of operations.

 Any decline in the internet as a significant advertising platform in the countries in which we operate could have a material adverse effect on our business, financial condition and results of operations.

We generate most of our revenues from the sale of online advertising in Russia. Although the use of the internet as a marketing channel in Russia is maturing, the level of overall spending on advertising in Russia remains relatively low compared to that in other developed countries. Broadband penetration rates in Russia are also relatively low compared to those in some other developed countries. The internet competes with traditional advertising media, such as television, print, radio and outdoor advertising. Although advertisers have become more familiar with online advertising in recent years, some of our current and potential customers have limited experience with online advertising, and have not historically devoted a significant portion of their marketing budgets to online marketing and promotion. As a result, they may be less inclined to consider the internet effective in promoting their products and services compared with traditional media.

Any decline in the appeal of the internet generally in Russia or the other countries in which we operate, whether as a result of increasing governmental regulation of the internet, the growth in popularity of other forms of media, a decline in the attractiveness of the internet as an advertising medium or any other factor, could have a material adverse effect on our business, financial condition and results of operations.

If our security measures are breached, malicious applications interfere with or exploit security flaws in our services, or our services are subject to attacks that degrade or deny the ability of users to access our products and services, our products and services may be perceived as not being secure, users and customers may curtail or stop using our products

15

and services, and we may incur significant legal and financial exposure.

Third parties have in the past attempted, and may in the future attempt, to use malicious applications to interfere with our services and may disrupt our ability to connect with our users. Such interference often occurs without disclosure to or consent from users, resulting in a negative experience that users may associate with Yandex. Such an attack could also lead to the destruction or theft of information, potentially including confidential or proprietary information relating to Yandex’s intellectual property, content and users. For example, if a third party were to hack into our network, they could obtain access to our search code. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. If an actual or perceived breach of our security occurs, the market perception of the effectiveness of our security measures could be harmed and we could lose users and customers.

Although we maintain substantial security measures, such measures may also be breached due to employee error, malfeasance, system errors or vulnerabilities, fraudulent actions of outside parties, or otherwise. Such security breaches may expose us to a risk of loss of this information, litigation, remediation costs, increased costs for security measures, loss of revenue, damage to our reputation, and potential liability.

In addition, we offer applications and services that our users download to their devices or that they rely on to store information and transmit information to others over the internet. These services are subject to attack by viruses, worms and other malicious software programs, which could jeopardize the security of information stored in a user’s device or in our computer systems and networks. These applications may be difficult to remove or disable, may reinstall themselves and may circumvent other applications’ efforts to block or remove them. If our efforts to combat these malicious applications are unsuccessful, or if our services have actual or perceived vulnerabilities, our reputation may be harmed, our user traffic could decline, and our communications with certain users could be impaired, which could adversely affect our business, financial condition and results of operations.

As the internet evolves, an increasing amount of online content may be held in closed social networks, mobile apps or proprietary document formats, which may limit the effectiveness of our search technology, which could adversely affect our brand, business, financial condition and results of operations.

Social networks are important players in the internet market, and have a significant degree of control over the manner and extent to which information on their websites can be accessed through third-party search engines.

In addition, a large amount of information on the internet is provided in proprietary document formats such as Microsoft Word and Adobe Acrobat. The providers of the software applications used to create these documents could engineer the document format to prevent or interfere with our ability to access the document contents with our search technology. Information can also be stored in other closed systems, such as mobile apps.

If social or other networks or software providers take steps to prevent their content or documents in their formats from being searchable, such content would not be included in our search results even if the content was directly relevant to a search request. These parties may also seek to require us to pay them royalties in exchange for giving us the ability to search content on their sites, in their networks or documents in their format and provide links thereto in our search results. If these parties also compete with us in the search business, they may give their search technology a preferential ability to search their content or documents in their proprietary format. Any of these results could adversely affect our brand, business, financial condition and results of operations.

We may not be able to prevent others from unauthorized use of our intellectual property rights, which may adversely affect our competitive position, our business, financial condition and results of operations.

We rely on a combination of patents, trademarks, trade secrets and copyrights, as well as nondisclosure agreements, to protect our intellectual property rights. Our patent department is responsible for developing and implementing our group-wide patent protection strategy in selected jurisdictions, and to date we have filed more than 600 patent applications, of which more than 200 have resulted in issued patents. The protection and enforcement of intellectual property rights in Russia and other markets in which we operate, however, may not be as effective as that in the United States or Western Europe. Also, the efforts we have taken to protect our proprietary rights may not be sufficient or effective. Any significant infringement of our intellectual property rights could harm our business, our brand and/or our

16

ability to compete, all of which could adversely affect our competitive position, our business, financial condition and results of operations.

We may be subject to intellectual property infringement claims, which are costly to defend, could result in significant damage awards, and could limit our ability to provide certain content or use certain technologies in the future.

A number of internet, technology, media and patent-holding companies own or are actively developing patents covering search, indexing, electronic commerce and other internet-related technologies, as well as a variety of online business models and methods. We believe that these parties will continue to take steps to protect these technologies, including, but not limited to, seeking patent protection in certain jurisdictions. As a result, disputes regarding the ownership of technologies and rights associated with online activities are likely to arise in the future. In addition, use of open-source software is often subject to compliance with certain license terms, which we may inadvertently breach.

With respect to any intellectual property rights claim, we may have to pay damages or compensation and/or stop using technology found to be in violation of a third party’s rights. We may have to seek a license for the technology, which may not be available on commercially reasonable terms or at all, and may significantly increase our operating expenses. We may be required to develop an alternative non-infringing technology, which may require significant effort, expense and time to develop. If we cannot license or develop technology for any potentially infringing aspects of our business, we may be forced to limit our service offerings and may be unable to compete effectively. We may also incur substantial expenses in defending against third-party infringement claims regardless of the merit of such claims.

We may be held liable for information or content displayed on, retrieved by or linked to our websites and mobile applications, or distributed by our users; or we may be required to block certain content or access to our websites could be restricted; any of which could harm our reputation and business.

The law and enforcement practice relating to the liability of providers of online services for the activities of their users is currently not settled in Russia and certain other countries in which we operate. Claims may be brought against us for defamation, libel, negligence, copyright, patent or trademark infringement, tort (including personal injury), fraud, other unlawful activity or other theories and claims based on the nature and content of information to which we link or that may be posted online via blogs and message boards, generated by our users or delivered or shared through our services, including if appropriate licenses and/or rights holder’s consents have not been obtained. For example, we have previously been involved in litigation regarding alleged copyright infringement in the United States. We are also regularly required to remove content uploaded by users on grounds of alleged copyright infringement, and from time to time we receive requests from individuals who do not want their names or websites to appear in our search results. Third parties may also seek to assert claims against us alleging unfair competition, data misappropriation, violations of privacy rights or failure to maintain the confidentiality of user data. Our defense of any such actions could be costly and involve significant time and attention of our management and other resources. If any of these complaints results in liability to us, the judgment or settlement could potentially be costly, encourage similar lawsuits, and harm our reputation and possibly our business.

The governments of the countries in which we operate are increasingly developing legislation aimed at regulation of the internet, in many places expanding liability and creating new obligations for companies which operate in the internet. For example, in 2017 new draft legislation was introduced which, if adopted, could require us to delist search results linking to websites that have been blocked in Russia for repeated copyright infringements. New legislation and regulations may impose additional new requirements on us and our operations and lead to material legal liability, which can be difficult to foresee or limit.

Additional recent legislation in Russia has introduced a system of information and website blocking measures both to prevent and stop copyright and related rights infringements and to prevent dissemination of illegal information, such as child pornography, content encouraging suicides and drug use, information on minors hurt by illegal actions and extremist information. The regulations generally require a request from the governmental authority to take down the allegedly infringing or illegal information prior to blocking of a particular website. However, in some cases, such as dissemination of extremist information, access to such information can be blocked without notification or prior judicial scrutiny. The categories of illegal information to which access can be restricted may be interpreted broadly or be expanded. In certain cases, even removal of illegal information does not eliminate the risk of website blocking or reinstate access to the blocked website. For example, Russian legislation allows for permanent blocking of websites for repeated violation of copyright and related rights. There is little clarity as to how this measure will be applied in practice. We may be subject to unpredictable blocking measures, injunctions or court decisions that may require us to block or remove content and may

17

adversely affect our services and operations. In addition, to ensure compliance with such laws we may be required to commit greater resources, or to limit functionality of our services, which may adversely affect the appeal of our services to our customers.

We rely on the continued availability, development and maintenance of the internet infrastructure in the countries in which we operate, including third-party providers of our principal internet connections and the equipment critical to our internet properties and services. Any errors, failures or disruption in the products and services provided by these third parties may materially adversely affect our brand, business, financial condition and results of operations.

Our future success will depend on the continued availability, development and maintenance of the internet infrastructure globally and particularly in the countries in which we operate. This includes maintenance of a reliable network backbone with the necessary speed, data capacity and security for providing reliable internet services. Any disruption in the network access provided by third parties or any failure by them to handle current or higher future volumes of use may significantly harm our business. We have experienced and expect to continue to experience interruptions and delays in service from time to time. Furthermore, we depend on hardware and software suppliers for prompt delivery, installation and service of servers and other equipment to deliver our services. The internet infrastructure may also be unable to support the demands placed on it by growing numbers of users and time spent online or increased bandwidth requirements. Government regulation may also limit our access to adequate and reliable internet infrastructure. Any outages or delays resulting from inadequate internet infrastructure or due to problems with our third-party providers could reduce the level of internet usage as well as our ability to provide our services to users, advertisers and network partners, which could materially adversely affect our business, financial condition and results of operations.

We may have difficulty scaling and adapting our existing technology architecture to accommodate increased traffic and technology advances or new requirements of our users and advertisers, which could adversely affect our business, financial condition and results of operations.

With some of the most highly visited websites in Russia, we deliver a growing number of services and page views to an increasing number of users. In addition, the services we offer have expanded and changed significantly and are expected to continue to do so in the future to accommodate bandwidth-intensive technologies and means of content delivery, such as interactive multimedia and video. Our future success will depend on our ability to adapt to rapidly changing technologies, to adjust our services to evolving industry standards and to maintain the performance and reliability of our services. Rapid increases in the levels or types of use of our online services could result in delays or interruptions in our services.

As we expand our services, we will need to continue to invest in new technology infrastructure, including data centers. We may have difficulty in expanding our infrastructure to meet any rising demand for our services, including difficulties in obtaining suitable facilities or access to sufficient electricity supplies. A failure to expand our infrastructure could materially and adversely affect our ability to maintain and increase our revenues and profitability and could adversely affect our business, financial condition and results of operations.

Certain technologies could block our ads, which may adversely affect our business, financial condition and results of operations.

Advertising displayed on our platforms may be interfered with by third parties, which may adversely affect our ability to attract advertisers. For example, third parties have in the past, and may in the future, employ technologies to block the display of ads on webpages. Ad-blocking technology, if used widely and effectively, would reduce the amount of revenue generated by the ads we serve and decrease the confidence of our advertisers and Yandex ad network partners in our advertising technology, which may adversely affect our business, financial condition and results of operations.

If we fail to detect click fraud or other invalid clicks, we may face litigation and may lose the confidence of our advertisers, which may adversely affect our business, financial condition and results of operations.

We are also exposed to the risk of fraudulent and invalid clicks on the ads we serve from a variety of potential sources. Invalid clicks are clicks that we have determined are not intended by the user to access the underlying content, including clicks resulting from click fraud executed by automated scripts of computer programs. We monitor our own websites and those of our partners for click fraud and proactively seek to prevent click fraud and filter out fraudulent or other invalid clicks. To the extent that we are unsuccessful in doing so, we credit our advertisers for clicks that are later

18

attributed to click fraud. If we are unable to stop these invalid clicks, these credits to our advertisers may increase. This could negatively affect our profitability, and these invalid clicks could result in legal claims or harm our brand.

Our business depends on the accuracy and reliability of our search results and dependability of our other services. A systems failure, technical interference or human error could prevent us from providing accurate search results or ads or reliably deliver our other services, which could lead to a loss of users and advertisers and damage our reputation and materially adversely affect our business, financial condition and results of operations.

Our business depends on our ability to provide accurate and reliable search results, which may be disrupted. For example, because our search technology ranks a webpage’s relevance based in part on the importance of the websites that link to it, people have attempted to link groups of websites together to manipulate search results. If our efforts to combat these and other types of “index spamming” are unsuccessful, our reputation for delivering relevant results could be harmed. This could result in a decline in user traffic, which may adversely affect our business, financial condition and results of operations.

Although we maintain robust network security measures, our systems are potentially vulnerable to damage or interruption from terrorist attacks, denial-of-service attacks, computer viruses or other cyber-attacks or attempts to harm our system, power losses, telecommunications failures, floods, fires, extreme weather conditions, earthquakes and similar events. Our data centers, which we maintain ourselves, are also potentially subject to break-ins, sabotage and intentional acts of vandalism, and to potential disruptions. The occurrence of a natural disaster or other unanticipated problems at our data centers could result in lengthy interruptions in our service, which could reduce our revenues and profits, and our brand could be damaged if people believe our services are unreliable.

From time to time, we have experienced power outages that have interrupted access to our services and impacted the functioning of our internal systems. Although we maintain back-up generators, these may not operate properly through a major sustained power outage or their fuel supply could be inadequate. Any unscheduled interruption in our services places a burden on our entire organization and would result in an immediate loss of revenue. If we experience frequent or persistent system failures on our websites, our reputation and brand could be permanently harmed. The steps we have taken to increase the reliability and redundancy of our systems are expensive, reduce our operating margin and may be insufficient to reduce the frequency or duration of unscheduled downtime.

Although we test updates before implementation and there were no significant downtime periods in recent years, errors made by our employees in maintaining or expanding our systems may damage our brand and may have a materially adverse effect on our business, financial condition and results of operations.

We acquire complementary businesses, teams and technologies from time to time, and may fail to identify additional suitable targets, acquire them on acceptable terms or successfully integrate them, which may limit our ability to implement our growth strategy. Acquisitions of new businesses may also lead to increased legal risks and other negative consequences, which could have an adverse effect on our business, financial condition and results of operations.

We regularly acquire other businesses, technologies and teams. The acquisition and integration of new businesses, technologies and people pose significant risks to our existing operations, including:

· additional demands placed on our management, who are also responsible for managing our existing operations;

· increased overall operating complexity of our business, requiring greater personnel and other resources;

· difficulties in expanding beyond our core expertise;

· significant initial cash expenditures or share dilution in connection with acquiring and integrating new businesses; and

· legal risks (including potential claims of the counterparty or of third parties), which may result from our lack of expertise in the field of the target’s business, incomplete or improper due diligence, misrepresentations by counterparties, and/or other causes.

19

The integration of new businesses presents a number of challenges, including differing cultures or management styles, poor financial records or internal controls on the part of the acquired companies, and an inability to establish control over cash flows. Furthermore, even if we are successful in integrating new businesses, expected cost and operating efficiencies may not materialize, the financial benefits from the acquisition may be less than anticipated, and we could be required to record impairment changes in respect of under-performing assets.

Moreover, our growth may suffer if we fail to identify suitable acquisition targets or are outbid by competing bidders. As a NASDAQ-listed company, we are subject to securities laws and regulations that, in certain circumstances, require that we file with the SEC audited historical financial statements for businesses we acquire that exceed certain materiality thresholds. Given financial reporting practices in Russia and other countries in which we operate, such financial statements and documented systems of internal controls over financial reporting are often not readily available or not capable of being audited to the standards required by U.S. securities regulations. As a result, we may be prevented from or delayed in pursuing acquisition opportunities that our competitors and other financial and strategic investors are able to pursue, which may limit our ability to implement our growth strategy.

Failure to maintain effective customer service may result in customer complaints and negative publicity and may adversely affect our business, financial condition and results of operations.

Customer complaints or negative publicity about our services or those offered by us (including services offered by our business units) or one of our joint ventures, or breaches of customers’ privacy or of our security measures, could diminish consumer confidence in and use of our services. Measures we implement to combat risks of fraud and breaches of privacy and security may be viewed as onerous by our customers or those of our joint venture and damage relations with them. Alternately, should breaches of customers’ privacy or of security measures occur, we could be subject to investigations and claims from governmental bodies, as well as from our customers. These measures heighten the need for prompt and accurate customer service to resolve irregularities and disputes. Effective customer service requires significant personnel expense, and such expense, if not managed properly, may impact our profitability or that of our one of our joint ventures. Any inability by us or our joint venture to manage or train our or their customer service representatives properly could compromise our or their ability to handle customer complaints effectively. In case of failure to maintain effective customer service by us or by one of our joint ventures, our reputation may suffer and we may lose our customers’ confidence, which may adversely affect our business, financial condition and results of operations.

The inherent limitations of the available data regarding internet usage and online advertising may make it difficult to assess our markets and our market position. 

We rely on and refer to information and statistics from various third-party sources, as well as our own internal estimates, regarding internet usage and penetration and the online advertising markets in the countries in which we operate. The information and statistics used in our industry are subject to inherent limitations reflecting the differing metrics and measurement methods utilized and applied by different sources; for example, data derived from computer usage contrasted to that derived from user surveys. In addition, while we believe that the available data and research on the Russian market is of comparable quality to that available in most developed countries, the data for Kazakhstan and Belarus are generally less consistent and reliable due to more limited third-party measurements in those countries.

We may be subject to claims from our current or former employees as well as contractors for copyright, trade secret and patent-related matters, which are costly to defend and which could adversely affect our business, financial condition and results of operation.

The software, databases, algorithms, images, patentable intellectual property, trade secrets and know-how that we use for the operation of our services were generally developed, invented or created by our former or current employees or contractors during the course of their employment with us within the scope of their job functions or under the relevant contractor’s agreement, as the case may be. As a matter of Russian law, we are deemed to have acquired copyright and related rights as well as rights to file patent applications with respect to such products, and have the intellectual property rights required for their further use and disposal subject to compliance with certain requirements set out in the Civil Code of Russia. We believe that we have appropriately followed such requirements, but they are defined in a broad and ambiguous manner and their precise application has never been definitively determined by the Russian courts. Therefore, former or current employees or contractors could either challenge the transfer of intellectual property rights over the products developed by them or with their contribution or claim the right to additional compensation for their works for hire and/or patentable results, in addition to their employment compensation. We may not prevail in any such action and

20

any successful claim, although unlikely to be material, could adversely affect our business and results of operation.

Risks Related to Doing Business and Investing in Russia and Other Countries in which We Operate

The legal system in Russia and other countries in which we operate can create an uncertain environment for investment and business activity that could have a material adverse effect on the value of our Class A shares, our business, financial condition and results of operations.

The legal framework supporting a market economy remains under development in Russia and the other countries in which we operate and, as a result, the relevant legal systems can be characterized by:

· rapid or unexpected changes in the legislative framework;

· inconsistencies between and among laws and regulations;

· gaps in the regulatory structure resulting from the delay in adoption or absence of implementing regulations and a subordinate legal framework;

· selective and inconsistent enforcement of laws or regulations, sometimes in ways that have been perceived as being motivated by political or financial considerations;

· limited or contradictory judicial and administrative guidance on interpreting legislation;

· relatively limited experience of judges and courts in interpreting recent and evolving commercial legislation as well as in understanding specifics of business operations and international best practices in the sphere of information technology and other areas;

· a perceived lack of judicial and prosecutorial independence from political, social and commercial forces;

· inadequate court system resources;

· a high degree of discretion on the part of the judiciary and governmental authorities; and

· poorly developed bankruptcy procedures that are not infrequently abused.

Any of these factors may result in our being subject to unpredictable fines or requirements, affect our ability to enforce our rights under our contracts or to defend ourselves against claims by others, or result in our being subject to unpredictable requirements, and could have a material adverse effect on our Class A shares and our business, financial condition and results of operations. The fact that we are a high-profile company may heighten this risk. See “—Businesses in Russia have on occasion been subject to actions by public authorities that some have characterized as unpredictable or politically motivated.”

Because the range of the services we provide is increasing and the legal framework governing the operations in our markets is evolving, we may be required to obtain additional licenses, permits or registrations or comply with other requirements, which may be costly or may limit our flexibility to run our business.

As we increase the range of services and diversify our business we may have to apply for additional licenses. Maintenance of granted licenses and obtaining new licenses may require us to spend additional resources. Licensing requirements may also limit our flexibility in running our business. Failure to maintain required licenses may significantly limit our ability to provide new services in respect of which these licenses are required.

Court interpretations and the applicability of Russian legislation and regulations in relation to our business can be ambiguous or contradictory and it is possible that the authorities may determine that we are required to have additional licenses, permits or registrations to provide our services. For example, we could fall within the regulations that require receipt of licenses/permits or compliance with certain mandatory procedures with respect to the provision of telecommunications services, the delivery of “mass media” and the use of encryption technologies by businesses.  Such

21

licensing or compliance processes may be time consuming and expensive and we may not be successful in acquiring any newly required licenses. Additionally, if we fail to obtain and maintain required licenses, permits or registrations or comply with certain mandatory procedures, we may face fines, penalties or sanctions.

As the legal framework in Russia continues to evolve, we may be required to take additional actions in order to comply with new legislation.  Although we believe that we are in full compliance with applicable laws, ambiguities in legislation and the wide discretion granted to regulatory authorities may result in us being subject to additional regulatory requirements. Compliance with additional or new regulatory requirements, or new interpretations or applications of existing requirements, may also require us to spend additional resources and limit our flexibility in providing our services.

New legislation under discussion in the Russian government may potentially affect the services we provide.  In particular, there have been proposals regarding the regulation of taxi services, including on-line taxi aggregators. Adoption of new regulation in this area may result in new duties and restrictions on our Taxi business. Recently, the Russian State Duma has also debated whether to impose new duties on the owners of social networks. The owners of social networks could be obligated to delete certain types of information from their websites at request of users. Although we believe that we would not be affected by such legislation, it could be interpreted in such a way that it affects our business. The Russian State Duma is also considering legislation that would regulate aggregators of information about goods and services offerings. If adopted, such proposals could result in the imposition of additional obligations and liability on the providers of such intermediary services and could require us to modify certain of our services, including Yandex.Mail, Yandex.Taxi and Yandex.Market, as well as spend additional resources in order to ensure compliance with new regulations. If we fail to comply with applicable legal requirements, we may face fines, penalties or sanctions.

Applicable legislation imposes restrictions and requirements on us with respect to processing of certain types of personal and other data and data retention which may impose additional obligations on us, limit our flexibility, or harm our reputation with users.

Collection and handling of user data by any entity or person in Russia and other countries may be subject to certain requirements and restrictions. If these requirements and restrictions are amended, interpreted or applied in a manner not consistent with current practice, we could face fines or orders requiring that we change our operating practices, which in turn could have a material adverse effect on our business, financial condition and results of operations.

In Russia, in order to store an individual’s personal data, we must obtain his or her written consent and use encryption and other technical means to protect his or her personal data. We do not collect or perform any operations on our users’ personal data, except when such collection or processing is in accordance with our terms of services and privacy policies which are available on our websites.   

Subject to several exemptions, processors of personal data must notify the appropriate Russian authority. We do not believe that we are required to make this notification.  However, due to the absence of established court practice and official guidelines on the application of the exemptions to notification, we cannot assure you that the regulator may not take a view that we nevertheless have to file a notification or comply with other requirements applicable to processors of personal data. If we are ultimately required to file such a notification or otherwise are determined to be subject to the rules regarding the collection and handling of personal data, we may be required to use special technical facilities and equipment and to adopt extensive internal compliance rules for the protection of personal data, which may adversely affect our ability to flexibly manage our business or make it more costly to do so.

Furthermore, we use cookies and other widespread technologies that assist us in improving the user experience and personalization of our products and services that ultimately benefit both our users and advertisers through behavioral targeting, which makes our advertising more relevant. There is no clarity as to whether our practices are compliant with the requirements of applicable data protection legislation in Russia and abroad, and such laws could be interpreted and applied in a manner that is not consistent with our current data protection practices.

Additionally, in Russia, “organizers of information distribution” are required to notify the relevant Russian authority about the commencement of their operations, and must retain a broad range of data relating to and generated by their users for a period of time, which must be provided to the authorities at their request. Our principal subsidiary operating in Russia has notified the relevant Russian authority that it acts as an organizer of information distribution with respect to some of the services it provides. Organizers of information distribution that use encryption when delivering or processing electronic messages have to provide the security authorities with information necessary for decoding the delivered or

22

processed messages. Compliance with these requirements may require significant expenditures by us, including additional data centers, servers and other infrastructure or software development. Data retention may also harm our reputation with users. If we fail to comply with the above requirements, the Russian authorities can block access to our services in Russia.

Under Russian law, companies are also required to store all personal data of Russian users in databases located inside Russia. Compliance with the requirements provided in this legislation may be practically difficult, require significant efforts and resources, could lead to legal liability in other jurisdictions and limit functionality of our services. Compliance with these requirements may also limit our ability to compete with other companies located in other jurisdictions that do not require mandatory local storage of personal data relating to their users. However, any non-compliance with this requirement could lead to legal liability and potentially to restriction of the availability of the service in Russia. For example, in 2016 a Russian court ordered the blocking of access to a popular social networking website for violation of data protection legislation.

Due to the nature of the services we offer and the fact that we have a presence in a number of countries, we may also be subject to data protection laws of other jurisdictions, especially laws regulating the cross-border transfer of personal data, which may require significant compliance efforts and could result in liability for violations in other jurisdictions. As our business grows we may also encounter increased pressure from foreign state authorities with respect to production of information related to users in circumvention of the international legal framework regulating the provision of such information. Any non-compliance with such requests may lead to liability and other adverse consequences.

Further, current law imposes restrictions on the distribution of satellite images of certain areas in Russia and the other countries in which we operate and imposes requirements with respect to the information provided by the traffic monitoring service we offer. If we were found to be in violation of any such restrictions, we may be forced to suspend such services or may potentially be subject to fines or other penalties.

We may be subject to existing or new advertising legislation that could restrict the types and relevance of the ads we serve, which would result in a loss of advertisers and therefore a reduction in our revenues.

Russian law prohibits the sale and advertising of certain products and heavily regulates advertising with respect to certain products and services. Ads for certain products and services, such as financial services, as well as ads aimed at minors and some others, must comply with specific rules and must in certain cases contain required disclaimers.

Further amendments to legislation regulating advertising may impact our ability to provide some of our services or limit the type of advertising we may offer. The application of these laws to parties, such as Yandex, that merely serve or distribute ads and do not market or sell the product or service, however, can be unclear. Pursuant to our terms of service, we require that our advertisers have all required licenses or authorizations. If our advertisers do not comply with these requirements, and these laws were to be interpreted to apply to us, or if our ad-serving system failed to include necessary disclaimers, we may be exposed to administrative fines or other sanctions, and may have to limit the types of advertisers we serve.

The regulatory framework in Russia governing the use of behavioral targeting in online advertising is unclear. If new legislation were to be adopted, or current legislation were to be interpreted, to restrict the use of behavioral targeting in online advertising, our ability to enhance the targeting of our advertising could be significantly limited, which could result in a loss of advertisers or a reduction in the relevance of the ads we serve, which would reduce the number of clicks on the ads and therefore our revenues.

Our need to comply with applicable Russian laws and regulations could hamper our ability to offer services that compete effectively with those of our foreign competitors and may adversely affect our business, financial condition and results of operations.

Many of our global competitors, such as Google and Microsoft, have their principal operations outside of Russia, putting them generally outside of the jurisdiction of Russian courts and government agencies, even though some of them have offices in Russia. Our systems and operations are located principally in Russia. Russian laws and regulations that are applicable to us, but not to our foreign competitors, may impede our ability to develop and offer services that compete effectively on a global scale as well as in Russia with those offered by our foreign-based competitors and generally available worldwide over the internet. Any inability on our part to offer services that are competitive with those offered by our foreign competitors may adversely affect our business, financial condition and results of operations.

23

Russian authorities could determine that we hold a dominant position in one or more of our markets, and could impose limitations on our operational flexibility that may adversely affect our business, financial condition and results of operations.

Russian anti-monopoly legislation imposes restrictions on companies that occupy a dominant position in a given market. We believe that the authorities have not to date focused on internet advertising in Russia to any significant extent, although we are aware of public statements by government officials suggesting that the authorities may analyze the business of online social networking. Were the Russian authorities to investigate the internet or online advertising industries, it is possible that they may conclude that, given our market share, we hold a dominant position in one or more of the markets in which we operate. Additionally, from time to time we receive information requests from Russian Federal Antimonopoly Service (FAS) related to certain of our services. If FAS deems that we hold a dominant position in one or more of the markets in which we operate this could result in limitations on our future acquisitions and a requirement that we pre-approve with the authorities any changes to our standard agreements with advertisers and Yandex ad network partners, as well as any specially negotiated agreements with business partners. In addition, if we were to decline to conclude a contract with a third party or terminate an existing agreement without sufficient substantiation this could, in certain circumstances, be regarded as abuse of a dominant market position.

Any abuse of a dominant market position could lead to administrative penalties and the imposition of fines of up to 15% of our prior year annual revenues in the relevant market. These limitations may reduce our operational and commercial flexibility and responsiveness, which may adversely affect our business, financial condition and results of operations.

Businesses in countries where we operate have on occasion been subject to actions by public authorities that some have characterized as unpredictable or politically motivated.

Many commercial laws and regulations in the markets where we operate are relatively new and have been subject to limited interpretation. As a result, their application can be unpredictable. In addition, government authorities have a tendency to follow a very formal approach in certain cases, are entrusted with a high degree of discretion and have at times exercised their discretion in ways that may be perceived as selective or unpredictable, and sometimes in a manner that is seen as being influenced by political or commercial considerations. Furthermore, significant uncertainty exists in the relevant markets in light of the broader geopolitical situation, which may result in the adoption or application of regulations based on political considerations.

For instance, in May 2017 Ukraine sanctioned two Yandex subsidiaries and prohibited usage of our services and websites by Ukrainian users. Yandex offices in Kiev and Odessa were subject to searches by the Ukrainian Security Service in connection with alleged breaches of law.

Although we believe that our commitment to content neutrality principles lessens the risk of politically motivated actions against us, we cannot guarantee that we will not be affected by politically motivated actions that could materially adversely affect our operations.

Existing restrictions on foreign ownership may prevent a takeover of our company by a non-Russian party. If the Russian government were to apply existing limitations on foreign ownership to our business, or specifically impose limitations on foreign ownership of internet businesses in Russia, it could materially adversely affect our group and the value of our Class A shares.

Russian law restricts foreign ownership of companies involved in certain strategically important activities in Russia. The relevant activities include activities connected with the use of encryption technologies that are subject to licensing. Currently, the internet and online advertising are not industries specifically covered by this legislation, but in the past there have been amendments under consideration by the Russian State Duma, which, if adopted, would include certain large internet companies within the scope of this law.

We believe that our Yandex.Money joint venture is subject to the above restrictions on foreign ownership because the Yandex.Money business currently holds an encryption license covered by the law. Since the completion of our joint venture in respect of  Yandex.Money in July 2013 following the sale by Yandex to Sberbank of 75% (less one ruble) of the total participation interest in Yandex.Money, we believe that the applicable restrictions in respect of private non-Russian persons no longer apply to Yandex, but that the requirement to obtain prior approval from the Russian Government

24

continues to be applicable to non-Russian state or international organizations or entities controlled by a non-Russian state or international organization that would seek to acquire shares of Yandex  or enter into an agreement that would establish direct or indirect control over Yandex and, therefore, trigger application of the law restricting foreign ownership. There is also a risk that some of the rights granted to Yandex N.V. under the joint venture agreement with Sberbank could be interpreted by Russian authorities as establishing control by Yandex over the Yandex.Money business, which would require the Russian Government’s preliminary consent for a broader number of transactions, including by private non-Russian persons. Moreover, because Yandex holds 25% (plus one ruble) in Yandex.Money, there is a risk that a change of control in respect of Yandex would require preliminary consent of the Central Bank of Russia, as Yandex could be considered to indirectly hold more than 10% of the voting power of a non-banking credit organization.

Other aspects of our business may be subject to restrictions on foreign ownership through the interpretation of current legislation in the future or through future legislation and we may be forced to take significant steps to modify our operating or ownership structure which could have a material adverse effect on our operations or the value of our Class A shares.

The Russian banking and financial systems remain less developed than those in some more developed markets, and a banking crisis could place liquidity constraints on our business and materially adversely affect our business, financial condition and results of operations.

Russia’s banking and other financial systems are less well-developed and regulated than those of some more developed markets, and Russian legislation relating to banks and bank accounts is subject to varying interpretations and inconsistent application. Russian banks generally do not meet international banking standards, and the transparency of the Russian banking sector lags behind international norms. In addition, the United States and European Union have imposed “sectoral” and related sanctions on named Russian banks in connection with developments in Ukraine. See “—Adoption and maintenance of embargo, economic or other sanctions, in particular with respect to the conflict in Ukraine, as well as similar measures against the countries in which we operate, may have a material adverse effect on our business, financial condition and results of operations.”

As a result, the banking sector remains subject to periodic instability. Another banking crisis, or the bankruptcy or insolvency of banks through which we receive or with which we hold funds, may result in the loss of our deposits or adversely affect our ability to complete banking transactions in Russia, which could have a material adverse effect on our business, financial condition and results of operations.

Some of our counterparties provide limited transparency in their operations, which could subject us to greater scrutiny and potential claims from government authorities.

We do business with a number of companies, especially small companies that do not always operate in a fully transparent manner and that may engage in unpredictable or otherwise questionable practices with respect to tax obligations or compliance with other legal requirements. We have been approached by government authorities regarding potential tax claims or other compliance matters in connection with such transactions. For example, in 2016 we received a claim from the Russian tax authority in respect of one of our distribution agreements with a Russian software developer. We have both appealed the tax authority’s claim and paid the claim in full.

As we are a larger and more transparent company with greater resources than such counterparties, governmental authorities may seek to collect taxes and/or penalties from us in relation to such transactions on the basis that we should have had knowledge of or aided such practices even when we did not.

Changes in the tax systems of Russia and other countries in which we operate, as well as unpredictable or unforeseen application of existing rules, may materially adversely affect our business, financial condition and results of operations.

Russian tax, currency, and customs laws and regulations are subject to varying interpretations and changes, which may be frequently revised and reviewed by the authorities. As a result, our interpretation of such tax legislation may be challenged by the relevant authorities. Russian tax legislation largely follows the OECD approach but may be implemented in a way which is not in line with international practice or our interpretation. Moreover, under the current conditions of weak economic growth and reduced tax revenue, the authorities are taking a more assertive position in their interpretation of the tax legislation and, as a result, it is possible that transactions and activities that have not been challenged in the past may now be questioned by the authorities. High-profile companies such as ours can be particularly vulnerable to such

25

assertive positions of the authorities.

Although we believe that our interpretation of relevant legislation is appropriate and is in accordance with existing court practice, if the authorities were successful in enforcing differing interpretations, our tax liability may be greater than the estimated amount that we have expensed to date and paid or accrued on our balance sheet.

Generally, Russian taxpayers are subject to inspection of their activities for a period of three calendar years immediately preceding the year in which an audit is carried out, with tax audits routinely undertaken at least every two years. A tax audit of our principal Russian subsidiary covering 2013 and 2014 was completed in 2016 and the resulting tax claims were fully accrued in our 2016 financial statements.

Taxes payable on dividends from our Russian operating subsidiaries to our parent company might not benefit from relief under the Netherlands‑Russia tax treaty.

In 2017, our principal Russian operating subsidiary distributed limited dividends to our parent company (Yandex N.V.) and applied withholding tax at a 5% rate in reliance on the provisions of the Netherlands‑Russia tax treaty.

Yandex is incorporated in the Netherlands and our principal operating subsidiaries are incorporated in Russia. Our management seeks to ensure that we conduct our affairs in such a manner that our parent company is regarded as the beneficial owner of all its incomes and not regarded as tax resident in any jurisdiction other than the Netherlands and, in particular, is not deemed to be a tax resident of, or to have a permanent establishment in, Russia. Thus, dividends paid from our Russian operating subsidiaries to our parent company should generally be subject to Russian withholding tax at a 5% rate. If our parent company were not treated as a Dutch resident for tax purposes or if it were deemed to have a permanent establishment in Russia, or if the Russian tax authorities were to determine that other conditions for the application of the 5% rate are not met because, for example, if Yandex N.V. is not deemed to be beneficial owner of the dividends received, dividends paid from our Russian operating subsidiaries to our parent company would be subject to Russian withholding tax at the rate of 15%.

Russian tax rules are characterized by significant ambiguities and limited interpretive guidance and are subject to change, and we can provide no assurance that dividend withholding tax relief may not be challenged by the Russian tax authorities based on the grounds mentioned above. Furthermore, Russian tax rules regarding residency and beneficial ownership which were recently introduced may change or their interpretation may evolve, thus triggering changes in taxation of dividends from our Russian subsidiaries to our parent company in the future.

Based on the current state of the law and available interpretations, we believe that Yandex and our material foreign subsidiaries should not be treated as controlled foreign corporations for Russian tax purposes. However, there are risks that any of these rules may be interpreted or applied in a manner that may have an adverse effect on our results of operations.

We may be required to record a significant deferred tax liability if we are unable to reinvest our earnings in Russia.

Our principal Russian operating subsidiary has significant accumulated earnings that have not been distributed to our Dutch parent company. Our current policy is to retain substantially all our earnings at the level of our principal subsidiary for investment in Russia.

We did not provide for dividend withholding taxes on the unremitted earnings of our non‑Dutch subsidiaries for 2012 or earlier years because we considered them to be permanently reinvested outside of the Netherlands. As of December 31, 2017, we had an accrual of RUB 1,324 million ($23.0 million) for dividend withholding tax. If circumstances change and we are unable to reinvest in that subsidiary’s current operations or acquire suitable businesses in Russia, U.S. GAAP would require us to record a deferred tax liability representing the dividend withholding taxes that we would be required to pay if this subsidiary were to pay these unremitted accumulated earnings to our Dutch parent company as a dividend, even if such dividends were not actually declared and paid. As of December 31, 2017, the cumulative amount of unremitted earnings in respect of which dividend withholding taxes have not been provided is RUB 58,795 million ($1,020.7 million). The applicable withholding tax rate is 5% and the amount of the unrecognized deferred tax liability related to these unremitted earnings was RUB 2,940 million ($51.0 million) as of December 31, 2017. We expect the amount of unremitted earnings to grow as our principal Russian operating subsidiary continues to

26

generate net income. If we were required to record a deferred tax liability on an amount subsequently made available for distribution it may have a material adverse effect on our results of operations.

Risks Related to Ownership of our Class A Shares

The price of our Class A shares has been and may continue to be volatile. Market fluctuations specific to Russia or developing markets or to high‑growth technology companies generally may affect the performance of our Class A shares and could expose us to potential securities litigation, which could result in substantial costs and a diversion of our management’s attention and resources.

Macroeconomic and geopolitical events in Russia in recent periods have adversely affected the value of traded securities of companies with significant operations in Russia, including our Class A shares. In addition, the market for technology and other growth companies has generally experienced severe price and volume fluctuations that have often been disproportionate to the operating performance of those companies. These broad macroeconomic, geopolitical, market and industry factors may impact the market price of our Class A shares regardless of our actual operating performance.

The trading price of our Class A shares has been and may continue to be volatile and subject to wide fluctuations in price in response to various factors, some of which are beyond our control. These factors include:

· macroeconomic and geopolitical developments, including those specific to the internet and online advertising both in Russia and globally;

· quarterly variations in our results of operations or those of our competitors;

· the level of use of internet search engines to find information;

· fluctuations in our share of the internet search market;

· the proportion of our revenues generated on our websites relative to those generated through the Yandex ad network or through distribution partners, as a result of the revenue sharing arrangements we enter into and the overall volume of advertising we provide our partners;

· announcements of technological innovations or new services and media properties by us or our competitors;

· the amount of advertising purchased or market prices for online advertising;

· the emergence of new advertising channels in which we are unable to compete effectively;

· the volume of searches conducted, the amounts bid by advertisers or the number of advertisers that bid in our advertising system;

· changes in governmental regulations, in particular those applicable to regulation of online business in Russian and globally;

· disruption to our operations or those of our partners;

· our ability to develop and launch new and enhanced services on a timely basis;

· commencement of, or our involvement in, litigation;

· any major change in our directors or management;

· changes in earnings estimates or recommendations by securities analysts;

27

· our ability to compete effectively for users, advertisers, partner websites and content;

· the operating and stock price performance of other companies that investors may deem comparable to us;

· fluctuations in the exchange rate between currencies, including the Russian ruble and the U.S. dollar; or

· general global or Russian economic conditions and slow or negative growth or forecast growth of related markets.

Additionally, volatility or a lack of positive performance in the price of our Class A shares may adversely affect our ability to retain key employees, some of whom have been granted equity awards.

This volatility may affect the price at which holders of Class A shares may sell such shares and the sale of substantial amounts of our Class A shares could adversely affect our trading price.

In the past, following periods of volatility in the overall market and the market price of a company’s securities, securities class action litigation has often been instituted against these companies. Such litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

The concentration of voting power with our principal shareholders, including our founders, directors and senior management, limits your ability to influence corporate matters, while a loss of voting control by our principal shareholders could affect the direction of our company.

Our Class B shares have ten votes per share and our Class A shares have one vote per share. As of February 15, 2018, our founder, directors, senior management (and their affiliates) and principal non‑institutional shareholders together own 93.69% of our outstanding Class B shares and 3.60% of our outstanding Class A shares, representing in the aggregate 55.57% of the voting power of our outstanding shares. In particular, our founder, Mr. Volozh, directly or indirectly controls 85.24% of our outstanding Class B shares and 0.14% of our outstanding class A shares representing in aggregate 49.23% of the voting power of our outstanding shares. For the foreseeable future, therefore, our founder, directors, senior management and their affiliates will have significant influence over the management and affairs of our company and over all matters requiring shareholder approval, including the election of directors, the amendment of our articles of association and significant corporate transactions, such as a sale of our company or its assets.

This concentrated control limits your ability to influence decisions on corporate matters. We may take actions that our public shareholders do not view as beneficial or as maximizing value for them. As a result, the market price of our Class A shares may be adversely affected.

At the same time, if our principal shareholders cease to have absolute voting control over Yandex N.V., as a result of conversions of Class B shares or the issuance of a substantial number of Class A shares, this may also present risks for our company and business. In such an event, it may be more difficult for us to obtain shareholder approval for matters that we believe are in the best interest of our business. 

Certain of our directors and shareholders and their affiliates may have interests that are different from, or in addition to, the interests of other Yandex shareholders.

Some of our directors are affiliated with investment funds or financial institutions that have investments in other businesses or entities that currently or may in the future compete with us. These affiliations may require such directors to recuse themselves from consideration of certain transactions or may otherwise create real, potential or perceived conflicts of interest.

Our Board of Directors and our priority shareholder have the right to approve accumulations of stakes in our company or the sale of our principal Russian operating subsidiary, which may prevent or delay change‑of‑control transactions.

Our Board of Directors has the right, acting by simple majority, to approve the accumulation by a party, group of related parties or parties acting in concert of the legal or beneficial ownership of shares representing 25% or more, in

28

number or voting power, of our outstanding Class A and Class B shares (taken together). If our board grants its approval of such share accumulation, the matter is then submitted to the holder of our priority share, which has a further right of approval of such accumulation of shares. In addition, any decision by our Board of Directors to transfer all or substantially all of our assets to one or more third parties, including the sale of our principal Russian operating subsidiary, is subject to the prior approval of the priority shareholder.

Any holding, transfer or acquisition by a party, group of related parties or parties acting in concert of the legal or beneficial ownership of Class B shares representing 25% or more, in number or by voting power, of our outstanding Class A and Class B shares (taken together), without the prior approval of our Board of Directors, first, and then the priority shareholder, will be null and void. The acquisition of shares in excess of the thresholds permitted by our articles of association will be subject to certain notification requirements set forth in our articles of association. Failure to comply with those terms would render the transfer of such shares null and void. In addition, the holders of such shares would not be entitled to the dividend or voting rights attached to their excess shares. The rights of our Board of Directors and our priority shareholder to approve accumulations of stakes in our company may prevent or delay change‑of‑control transactions.

Anti‑takeover provisions in our articles of association and the shareholders agreement among our principal shareholders may prevent or delay change‑of‑control transactions.

In addition to the rights of our board and of the priority shareholder to approve the accumulation of stakes of 25% or more, as described above, our multiple class share structure may discourage others from initiating any potential merger, takeover or other change‑of‑control transaction that our public shareholders may view as beneficial. Our articles of association also contain additional provisions that may have the effect of making a takeover of our company more difficult or less attractive, including:

· the staggered three‑year terms of our directors, as a result of which only one‑third of our directors are subject to election in any one year;

· a provision that our directors may only be removed by a two‑thirds majority of votes cast representing at least 50% of our outstanding share capital;

· the authorization of a class of preference shares that may be issued by our Board of Directors in such a manner as to dilute the interest of any potential acquirer;

· requirements that certain matters, including an amendment of our articles of association, may only be brought to our shareholders for a vote upon a proposal by our Board of Directors;

· minimum shareholding thresholds, based on par value, for shareholders to call general meetings of our shareholders or to add items to the agenda for those meetings, which will be very difficult for Class A shareholders to meet given our multiple class share structure; and

· supermajority requirements for shareholder approval of certain significant corporate actions, including the legal merger or demerger of our company and the amendment of our articles of association.

The Dutch public offer rules, which impose substantive and procedural requirements in connection with the attempted takeover of a Dutch public company, only apply in the case of Dutch target companies that have shares listed on a regulated market within the European Union. We have not listed our shares, and do not expect to list our shares, on a regulated market within the European Union, and therefore these rules do not apply to any public offer for our Class A shares.

We rely on NASDAQ Stock Market rules that permit us to comply with applicable Dutch corporate governance practices, rather than the corresponding domestic U.S. corporate governance practices, and therefore your rights as a shareholder differ from the rights you would have as a shareholder of a domestic U.S. issuer.

As a foreign private issuer whose shares are listed on the NASDAQ Global Select Market, we are permitted in certain cases to follow Dutch corporate governance practices instead of the corresponding requirements of the NASDAQ

29

Marketplace Rules. We follow Dutch corporate governance practices with regard to the quorum requirements applicable to meetings of shareholders and the provision of proxy statements for general meetings of shareholders. In accordance with Dutch law and generally accepted business practices, our articles of association do not provide quorum requirements generally applicable to general meetings of shareholders. Although we do provide shareholders with an agenda and other relevant documents for the general meeting of shareholders, Dutch law does not have a regulatory regime for the solicitation of proxies and the solicitation of proxies is not a generally accepted business practice in the Netherlands. Accordingly, our shareholders may not be afforded the same protection as provided under NASDAQ’s corporate governance rules.

We do not comply with all the provisions of the Dutch Corporate Governance Code. This may affect your rights as a shareholder.

As a Dutch company we are subject to the Dutch Corporate Governance Code, or DCGC. The DCGC contains both principles and best practice provisions for management boards, supervisory boards, shareholders and general meetings of shareholders, financial reporting, auditors, disclosure, compliance and enforcement standards. The DCGC applies to all Dutch companies listed on a government‑recognized stock exchange, whether in the Netherlands or elsewhere, including the NASDAQ Global Select Market. The principles and best practice provisions apply to the board (in relation to role and composition, conflicts of interest and independence requirements, board committees and remuneration), shareholders and the general meeting of shareholders (for example, regarding anti‑takeover protection and obligations of the company to provide information to its shareholders) and financial reporting (such as external auditor and internal audit requirements). The DCGC requires that companies either “comply or explain” any noncompliance and, in light of our compliance with NASDAQ requirements and as permitted by the DCGC, we have elected not to comply with all of the provisions of the DCGC. This may affect your rights as a shareholder and you may not have the same level of protection as a shareholder in a Dutch company that fully complies with the DCGC.

Because of the secondary listing of our Class A shares on the Moscow Stock Exchange, we are subject to additional disclosure and compliance requirements that may conflict with those imposed by the SEC and NASDAQ, and we may experience trade fluctuations based on arbitrage activities.

In June 2014, we established a secondary listing of our Class A shares on the Moscow Stock Exchange. Pursuant to that listing, we and our insiders must comply with certain disclosure and other obligations that may differ in timing and substance from those applicable to our NASDAQ listing. In addition, many of the obligations imposed by the Moscow Stock Exchange are formalistic in nature, and that exchange has limited experience in the application of its requirements to companies incorporated outside Russia. As a result, we may not be able to comply with all formal obligations in a manner that is consistent with the requirements or interpretations of that exchange.

In addition, this secondary listing may create opportunities for trading arbitrage, particularly in connection with currency fluctuations between the trading in U.S. dollars on NASDAQ and in rubles on the Moscow Stock Exchange, which could impact the trading price of our Class A shares.

Risks for U.S. Holders

We cannot assure you that we will not be classified as a passive foreign investment company for any taxable year, which may result in adverse U.S. federal income tax consequence to U.S. holders.

Based on certain management estimates with respect to our gross income and the average value of our gross assets and on the nature of our business, we believe that we were not a “passive foreign investment company,” or PFIC, for U.S. federal income tax purposes for the 2017 tax year, and do not expect to be a PFIC in the foreseeable future. However, because our PFIC status for any taxable year will depend on the composition of our income and assets and the value of our assets in such year, and because this is a factual determination made annually after the end of each taxable year and there are uncertainties in the application of the rules, there can be no assurance that we will not be considered a PFIC for the current taxable year or any future taxable year. In particular, the value of our assets may be determined in large part by reference to the market price of our Class A shares, which has fluctuated, and may continue to fluctuate, significantly. If we were to be treated as a PFIC for any taxable year during which a U.S. holder held our Class A shares, certain adverse U.S. federal income tax consequences could apply to the U.S. holder. See “Taxation—Taxation in the United States—Passive foreign investment company considerations.”

30

Any U.S. or other foreign judgments you may obtain against us may be difficult to enforce against us in Russia or the Netherlands.

We have only very limited operations in the United States, most of our assets are located in Russia, our company is incorporated in the Netherlands, and most of our directors and senior management are located outside the United States. As a result, it may be difficult to serve process on us or these persons within the United States. Although arbitration awards are generally enforceable in Russia and the Netherlands, and Russian courts may elect to enforce foreign court judgments as a matter of international reciprocity and judicial comity, you should note that judgments obtained in the United States or in other foreign courts, including those with respect to U.S. federal securities law claims, may not be enforceable in Russia or the Netherlands. There is no mutual recognition treaty between the United States and the Russian Federation or the Netherlands, and no Russian federal law or Dutch law provides for the recognition and enforcement of foreign court judgments. Therefore, it may be difficult to enforce any U.S. or other foreign court judgment obtained against our company, any of our operating subsidiaries or any of our directors in Russia or the Netherlands.

The rights and responsibilities of our shareholders are governed by Dutch law and differ in some important respects from the rights and responsibilities of shareholders under U.S. law.

Our corporate affairs are governed by our articles of association and by the laws governing companies incorporated in the Netherlands. The responsibilities of members of our Board of Directors under Dutch law are different than under the laws of some U.S. jurisdictions. In the performance of its duties, our Board of Directors is required by Dutch law to consider the interests of Yandex, its shareholders, its employees and other stakeholders and not only those of our shareholders. Also, as a Dutch company, we are not required to solicit proxies or prepare proxy statements for general meetings of shareholders.

In addition, the rights of our shareholders are governed by Dutch law and our articles of association, and differ from the rights of shareholders under U.S. law. For example, Dutch law does not grant appraisal rights to a company’s shareholders who wish to challenge the consideration to be paid upon a merger or consolidation of the company.

Item 4.  Information on the Company.

History and Development of the Company; Organizational Structure.

Our founders began the development of our search technology in 1989, and launched the yandex.ru website in 1997.

In 2007, we undertook a corporate restructuring, as a result of which Yandex N.V. became the parent company of our group. Yandex N.V. is a Dutch public company with limited liability. Its registered office is at Schiphol Boulevard 165, 1118 BG, Schiphol, the Netherlands (tel: +31‑20‑206‑6970). The executive offices of our principal operating subsidiary are located at 16, Leo Tolstoy Street, Moscow 119021, Russian Federation (tel. +7‑495‑739‑7000).

Business Overview

Our Business

Yandex is one of the largest internet companies in Europe, operating Russia’s most popular search engine and its most visited website. Yandex’s goal is to help consumers and businesses better navigate the online and offline worlds. Since 1997, Yandex has delivered world-class, geographically relevant search and locally tailored experiences on all digital platforms, based on innovative technologies. Additionally, we have developed market-leading on-demand transportation services, navigation products, and other mobile applications for millions of consumers across the globe.

Yandex is a technology company that builds intelligent products and services powered by machine learning. Our products and services are based on complex, unique technologies that are not easily replicated. Benefiting from Russia’s long‑standing educational focus on mathematics and engineering, we have drawn upon the considerable local talent pool to create a leading technology company.

31

We derive substantially all of our revenues from online advertising. We enable advertisers to deliver targeted, cost‑effective ads that are relevant to our users’ needs, interests and locations. We serve ads on our own search results and other Yandex webpages, as well as on thousands of third‑party websites that make up our Yandex ad network. Through our ad network, we extend the audience reach of our advertisers and generate revenue for both our network partners and us. We offer a variety of ad formats to our advertisers, including performance-based, brand and video advertising formats across different platforms. Other revenue streams come from our e‑commerce offerings, ride-sharing service, classifieds, and other initiatives, including music subscription and event tickets sales within our Media Services.

Our businesses are organized in the following operating segments:

· Search and Portal, which includes all our services offered in Russia, Belarus and Kazakhstan (and, for periods prior to the imposition of sanctions on Yandex by the government of Ukraine in May 2017, all our services offered in Ukraine), other than those described below;

· E‑commerce (including the Yandex.Market service, which we expect to form a joint venture with Sberbank in 2018, when the deal is closed);

· Taxi (including the Yandex.Taxi service, which combined with Uber’s ride-sharing business in Russia and neighboring countries in February 2018, as well as Yandex.EATs, our food delivery business, which consists of FoodFox, acquired in December 2017, and Uber.EATs business, which will be contributed as a result of the transaction with Uber);

· Classifieds (including Auto.ru, Yandex.Realty, Yandex.Jobs and Yandex.Travel); and

· Experimental businesses, including:

· Media Services (including KinoPoisk, Yandex.Music, Yandex.Afisha and Yandex.TV Program);

· Yandex Data Factory;

· Discovery Services (including Yandex Zen and Yandex Launcher); and

· Search and Portal in Turkey.

Our experimental businesses aim to create new business models. Once an experimental business becomes sizable enough, justifies a new business model, and has good prospects for future development, we may decide to break it out from our Experiments and create a separate segment. Unsuccessful experiments may be shut down or reabsorbed by one of our other segments. From January 1, 2018, we separated out Media Services from Experiments to form a new Media Services business unit and will now report its financial results separately.

Search and Portal

We offer a broad range of world-class, locally relevant search and information services that are free to our users and that enable them to find relevant information quickly and easily.

Yandex Search

Our search engine offers almost instantaneous access to the vast range of information available online. We utilize linguistics, mathematics, machine learning and AI to develop proprietary algorithms that efficiently extract, compile, systematize and present relevant information to users. Our organic search results are ranked by computer algorithms based exclusively on relevance, and we clearly segregate organic results from paid results to avoid confusing our users.

Yandex Search generated 55.1% of all search traffic in Russia in 2017 and 56.4% in February 2018, according to Yandex.Radar, a search traffic and browser usage analytics tool based on Yandex.Metrica data. In 2017 our search share on desktop and mobile reached 65.3% and 41.7%, respectively. In February 2018 our search share averaged 67.5%

32

on desktop and 44.6% on mobile, respectively, with mobile search share of 46.1% on Android and 38.4% on iOS. The percentage of our total search traffic, generated from mobile devices averaged approximately 39% in Q4 2017 compared with 31% in Q4 2016, while the percentage of our search revenues generated from mobile devices increased to approximately 31% from approximately 25% in these periods.

Geolocation Services

Yandex.Maps. Our Yandex.Maps provide high‑quality, detailed maps of Russia and neighboring countries. We also provide a detailed map of Turkey and a map of the whole world. We offer our users panoramic views, public transportation routes, driving directions with voice controls and turn-by-turn navigation.

We use our technology and licenses to create and edit maps from raw data, including satellite images, GPS coordinates and live user feedback. Yandex.Maps is also available via application programming interfaces, or APIs, which allow developers to embed and use our interactive maps in third‑party websites and applications, as well as to add extra layers of information—for example, to offer a map showing the location of a restaurant or a hotel.

We also offer Yandex.Navigator, our mobile application that provides turn‑by‑turn navigation, incorporates a voice input function, speed limit warnings, parking information, natural guidance features  as reference points along a route, voice notifications for accidents, road works etc. It is one of Yandex’s most popular mobile apps in terms of usage.

Navigator is also one of the essential components of Yandex.Auto, our voice-activated in-car infotainment system, which offers Yandex’s best-in-class mapping and navigation, our music streaming, weather information and other services. We work with car manufacturers on equipping cars with Yandex.Auto. Yandex.Auto is already available in some models of Toyota and Honda on the Russian market.

The Yandex.Transport app provides users with real‑time data on public transport in a number of Russian cities. It also operates in Helsinki and Tampere, Finland; Budapest, Hungary; Sydney and Brisbane, Australia; and Auckland, New Zealand.

Yandex Business Directory provides users with a comprehensive list of businesses, detailed information about them, as well as search option for services and goods.

In February 2018, we launched our Yandex.Drive car-sharing service which offers on-demand access to a fleet of 750 vehicles. Yandex.Drive usage is billed on a per minute basis and Yandex integrates traffic conditions and customer demand to provide dynamic pricing at the time of reservation. The price includes fuel, parking, and insurance.

Our map based apps allow offline businesses to place ads in native formats (adopted for different scenarios on the map). These formats target potential clients of those businesses while they are using Yandex.Maps and/or Navigator.

Personal Services

Yandex.Mail. Yandex.Mail provides users with fast and easy access to their email.

Yandex.Disk is our cloud‑based storage service that allows users to upload, store and share content online. Since late 2017 we have been providing unlimited storage space for the content uploaded through Yandex.Disk mobile app.

Yandex.News is the most visited online news aggregation service in Russia, providing a comprehensive media overview for our users. We aggregate and present local, national and international news. The selection of news is fully automated and editorial-free.

Yandex.Weather

Our Yandex.Weather service offers hyperlocal, real-time weather information based on our proprietary weather forecasting technology, Meteum. Powered by machine learning, it gives accurate forecasts for areas as local as individual neighborhoods across the world.

33

Yandex Browser

Our Yandex Browser is the second most popular browser on desktops and the most popular non-native browser on mobile platforms in Russia. Yandex Browser is committed to delivering high-quality user experiences and protecting web audiences. Yandex.Browser’s built-in Antishock technology blocks malicious and fraudulent advertising and its “Protect” technology offers comprehensive protection against the majority of online threats. For example, Yandex.Browser checks all downloaded files for viruses, warning users about dangerous websites, encrypting users’ passwords when using public Wi-Fi networks, and ensuring safe payments. Recently, we have introduced native ad blocking in the Russian version of Yandex Browser to enhance users’ browsing experience by filtering intrusive advertising.

The combined share of desktop and mobile searches processed through Yandex Browser in Russia reached 19.6% in February 2018, according to Yandex.Radar.

Yandex Search App

In 2017 we significantly upgraded our Yandex Search App by integrating Yandex’s must-have services into one app, including Search, Maps, News, Zen, Weather and many others. In October 2017 we enhanced our Search App with Alice, the first conversational voice assistant on the Russian market. In 2017 our Search App was the fastest growing search app on the Russian market. In December 2017 it became the third most downloaded app in Google Play in Russia.

Turbo pages

We launched Turbo pages in mid-2017. Turbo pages is a new format of displaying content on mobile devices, which loads several times faster than regular web pages and are optimized for smaller screens. Our Turbo pages are easier to implement compared to other similar products globally and offer monetization from Yandex out of the box. Turbo pages are available on Search, Zen and News.

Alice

In October 2017, we launched Alice, the first conversational intelligent assistant for the Russian market. Alice assists users with a wide array of information needs, such as factoid questions, weather forecasts, directions and currency exchange rates. Alice is not limited to predefined scenarios and includes a general chit-chat mode – a unique feature among intelligent assistants that has been enthusiastically embraced by millions of users. It also benefits from the near-human level of speech recognition accuracy (based on the Word Error Rate measurement) provided by the Yandex SpeechKit platform. As of today, Alice integrates many Yandex services such as Search, News, Weather, Music, Maps, and Taxi, and also includes over a dozen games. The external skills platform for Alice is currently in beta, and includes such skills as ordering from Papa John’s Pizza. Alice is available in Russian in the Yandex Search app and Yandex.Browser on iOS and Android, as well as with Yandex Browser on Windows.

Our Monetization and Advertiser Services

We offer a variety of ad formats to our advertisers, including performance-based, brand and video advertising formats.

Performance‑based ads are principally targeted to a particular user query on our search engine result pages, and on search result pages of our partners, as well as to the content of a particular website or webpage being viewed, or to user behavior or characteristics. Such ads are clearly marked as paid advertising and are separate from our organic search results and non-advertising content.

Most of our revenues are generated from performance‑based advertising, on a pay‑per‑click basis, with a smaller portion generated from brand advertising and video advertising, based on the number of impressions delivered. We actively monitor the ads we serve, both automatically and manually, in order to help ensure the relevance of the ads as well as compliance with applicable laws.

34

Yandex.Direct

Yandex.Direct is our auction‑based advertising placement platform, which uses auction theory and relies on our distributed infrastructure to process millions of auctions every day. Yandex.Direct lets advertisers cost‑effectively deliver relevant ads targeted at particular search queries or content on Yandex websites or third‑party websites in the Yandex Advertising Network. Advertisers may use our automated tools, often with little or no assistance from us, to create performance‑based ads, bid on keywords that are likely to trigger the display of their ads, and set total spending budgets. Yandex.Direct features an automated, online sign‑up process that enables advertisers to create and quickly launch their advertising campaigns. Advertisers may also work with our sales staff to design and implement more specialized or sophisticated advertising campaigns. Recently we enhanced Yandex.Direct with an opportunity to place display ads right in the system. We also offer a Yandex.Direct mobile app to better facilitate advertisers’ access to our service to manage their advertising campaigns.

Performance‑based ads on our desktop search engine results page (SERP) appear in one of several general categories: top placement, appearing above the organic search results and featuring up to four paid links on desktop and up to three paid links on mobile; and a southern block, which appears either below the organic search results or the right-hand block located to the right of the organic search results, featuring up to nine paid links in total on desktop and up to one paid link on mobile. In late 2017 we started to test the concept of Templates – our new ad placement formats tailored to a search query of a particular user. Templates allow users to dynamically enrich an advertisement with additional elements, such as quick links, contact information, working hours, merchants’ ratings, images and others. Subsequently we announced the change in our search engine results page layout. Instead of our typical ad placement blocks, paid links will be mixed with organic search links, while our algorithms will choose which format is more appropriate and efficient in each particular situation in order to provide a more personalized SERP. The advertisers will bid for the amount of traffic they want to purchase, instead of traditional bidding for a specific ad placement block. As previously, Yandex.Direct will continue to use a Vickrey‑Clarke‑Groves (VCG) auction to serve ads on our SERP.

Yandex Ad Network

Our Yandex Advertising Network partners include search websites, for which we provide search capabilities, as well as contextual network partners, where we serve ads based on user behavior or characteristics or website content. Among our partners are some of the largest Russian websites, including Mail.ru, Rambler, Bing, Avito.ru, Gismeteo.ru and others.

We help third‑party website owners monetize their content while extending the reach of our advertisers. Through the Yandex Advertising Network, our partners can deliver performance‑based ads on their search results pages or websites. Our advertising algorithms use our proprietary MatrixNet technology, which optimizes the click‑through rate on our network through improved click prediction. We screen applicants for the Yandex Advertising Network and favor websites with high‑quality content and stable audiences to offer advertisers high quality traffic.

Yandex’s video advertising network allows users to place full-screen videos, video ads on pages of websites and ads within the video content available on over 200 advertising platforms, including desktop and mobile websites, mobile and Smart TV applications. Yandex’s technologies enable users to provide advertising to the targeted audience and receive the information about its efficiency.

Programmatic advertising

We have developed a range of programmatic advertising products, which utilize real‑time bidding, or RTB, technologies to provide effective solutions to our publisher and advertiser partners. Our RTB ad exchange connects our performance‑based demand‑side platform (DSP) Yandex.Direct, to our display‑based DSP (called AWAPS) as well as to integrated third-party DSPs. Our RTB ad exchange leverages the wealth of targeting data generated by our own Data Management Platform, including Crypta, search and browsing history, etc. The RTB ad exchange is connected to many of our Yandex Advertising Network partners who have chosen to display ads from our RTB ad exchange as well as or in lieu of our regular Yandex.Direct ads. In addition, through the acquisition of ADFOX, we provide a supply‑side platform to our publisher partners. ADFOX is able to mediate in real‑time between programmatic brand ads from AWAPS, performance‑based ads from Yandex.Direct, ads from integrated third party DSPs and the publisher’s own direct sales.

35

Mobile Advertising

We offer our advertisers the ability to display ads on mobile versions of Yandex services, including Zen, our Advertising Network partner websites, and in mobile applications. Advertisers are able to set up their mobile bid as a coefficient of their desktop bid.

Analytics tools

Our web analytics system, Yandex.Metrica, has the largest coverage among web analytics platforms in Russia. It is also the second most popular web analytics system tool in the world offering advertisers and website owners tools such as machine-learning based bot traffic detection, referral spam filtering, raw logs export and unsampled data collection and reporting regardless of the traffic volume. It allows advertisers in near real‑time to analyze the “post‑click” behavior of users to evaluate the key efficiency parameters of their advertising campaigns — for example, to analyze the conversion rate, or the cost of attracting a visitor who performs the desired action. Based on these data, our advertising customers are able to choose the most efficient tools and settings for their advertising campaigns.

We also provide users with AppMetrica, a marketing platform for app install attribution, app analytics, and push campaigns, that allows to track all kinds of ad campaigns.

Yandex.Radar is our analytical tool, which provides advertisers, webmasters, analysts, and other internet marketing professionals with accurate statistics on the internet market in different countries. Yandex.Radar is based on Yandex.Metrica aggregated data and provides statistics on search market shares and browser usage, as well as traffic breakdown by operating system and device type.

E‑commerce

Launched in 2000, Yandex.Market is one of the most popular services in Russia, providing product information, price comparisons and consumer generated reviews of products and online retailers. We aggregate price, product and availability information from thousands of active online and “brick and mortar” retailers, and currently feature approximately 150 million offerings in more than 2,500 product categories from approximately 21,000 domestic and international merchants.

Yandex.Market is priced on a cost‑per‑click (CPC) basis, similar to Yandex.Direct and also operates on a take-rate-based model. Starting from August 2017 we allow offline stores, which do not have their own websites, to place the products on Yandex.Market under a take-rate-based model.

In August 2017, Yandex and Sberbank of Russia announced that the companies intend to combine the technological capabilities of Yandex and the infrastructure and technologies of Sberbank to develop a leading e-commerce ecosystem. In December 2017, the two parties entered into a binding agreement to form a joint venture based on the Yandex.Market platform. Yandex.Market will engage in e-commerce, with a core focus on creating a B2C online retail marketplace. We expect the deal to close in the first half of 2018.

In addition, in October 2017, we started testing our fulfillment center operated by a third party partner to provide users with fully-fledged solutions and improve the purchasing experience.

Taxi

Yandex.Taxi is our ride-sharing service, established in 2011. The service benefits from our robust expertise in machine learning and our world-class navigation and mapping technologies, allowing us to increase efficiency and improve fleet utilization. From late 2016, we have been aggressively investing in geographical expansion. In 2017 Yandex.Taxi added 97 cities with 100,000+ population and 38 cities with population of 50,000+. As of December 2017, the service was available in 167 cities with 100,000+ population, and in 56 cities with population of 50,000+ across Russia, Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan and Moldova.

We continue developing our ride-sharing service to provide the best user experience. Our forward dispatch technology allows us to better utilize the fleet, our smart pick-up points allow users to more efficiently allocate travel time and reduce fares, our upfront pricing, which provides fixed pricing for the trip, is also appreciated by users.

36

In July 2017 we entered into a landmark transaction between Yandex.Taxi and Uber to combine our ride-sharing businesses in Russia and neighboring countries. This transaction became a testament to the technological strength of Yandex. The potential synergy effects from Yandex’s deep technological expertise and the global ride-sharing expertise of Uber will allow the combined company to become a regional leader on the ride-sharing market, offering better quality service to our riders, drivers and cities. As of December 2017, the combined company operated in 168 cities with 100,000+ population and in 56 cities with population of 50,000+ across Russia, Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan and Moldova.

Having received all necessary regulatory approvals, Yandex.Taxi and Uber completed the combination of their ride-sharing businesses on February 7, 2018. Uber invested $225 million and Yandex invested $100 million in cash in the combined company, the combined business had more than $400 million in cash on hand at closing, with a combined company valuation in excess of $3.8 billion on a post money basis. The combined company is held approximately 59.3% by Yandex, 36.9% by Uber, and 3.8% by employees of the group on a fully diluted basis.

Tigran Khudaverdyan, ex-CEO of Yandex.Taxi, became the CEO of the combined business. The combined company supervisory board consists of four designees of Yandex and three designees of Uber.

After the closing of the transaction, consumers will be able to use both Yandex.Taxi and Uber apps while the driver-side apps will be integrated, leading to shorter passenger wait times, increased driver utilization rates, and higher service reliability.

In late December 2017, Yandex acquired FoodFox, a leading player in food delivery service. In the second quarter of 2018, as part of the transaction between Yandex.Taxi and Uber, UberEATs will also be contributed to the combined company. In 2018 FoodFox and UberEATs will operate under the Yandex.EATs brand. We believe that food delivery has clear synergy with our ride-sharing operations.

Classifieds

Yandex’s Classifieds business unit includes Auto.ru, Yandex.Realty, Yandex.Jobs and Yandex.Travel.

Auto.ru is our classifieds platform for used and new cars, commercial vehicles and spare parts. Our goal is to provide our users with the means to find the exact car they are looking for. We care about the quality of the cars advertised on our platform. Auto.ru runs certification centers for used cars, which allow sellers to have their cars inspected along up to 300 parameters; in 2017 we had a total of 5 certification centers in Moscow and St. Petersburg. Moreover, in Q4 2017 we added to the listings free vehicle history that allows to check all the information on vehicle operation, road accidents received from the government databases and other. In May 2017, Auto.ru launched an aggregator of auto service centers, which allows users to choose an appropriate autoservice for an appointment among 65,000 auto service centers available in Russia. In addition, Auto.ru keeps developing spare parts classifieds, which were launched in 2016.

Auto.ru continues strengthening its position in the markets. According to the third party advertising agency, working with dealerships, in December 2017, Auto.ru generated 71% of all calls from auto classifieds to dealers in Moscow and 60% in St. Petersburg. We continue growing our market share in the regions. In addition to organic growth, in 2017 we strengthened our competitive position through acquisitions, closing a deal with Hearst Shkulev Media, the largest media company in the Urals, for 30 auto classifieds domains in the regions, and signing a deal with 24auto.ru, the leading auto classified in Krasnoyarsk region.

We monetize Auto.ru through advertising, value added services (VAS) and listing fees for dealers and individuals selling more than one car per month.

Yandex.Realty is our real estate classifieds platform for private individuals and realtors. The service provides listings for both the sale and rental of apartments, rooms, houses and vacation homes. In 2015 we added the option to place listings for apartments in newly‑built or under‑construction apartment complexes in several cities, including Moscow, St. Petersburg, Ekaterinburg and other cities.  

Yandex.Jobs, our service for job seekers, was launched in 2010 and underwent a complete redesign in 2015, with the new version initially launched as a mobile app for Android and iOS. The focus of the new version is on blue

37

collar and service industry jobs. Job search is highly simplified and users can call the potential employer directly from the app. The service aggregates vacancies from a number of partners.

Yandex.Travel is our tour aggregator service. Starting from 2018, Yandex.Tarvel became a part of Search and Portal segment.

Experiments

Aside from our core business and our separate business units, we have a number of divisions that we currently consider to be experimental in nature. We believe that some of them have a good chance of transforming into separate business units in the future.

Media Services

Our Media Services provides our users with streaming audio, video and other entertainment data. Media Services includes our entertainment services – Yandex.Music, KinoPoisk, Yandex.Afisha and Yandex.TV Program – with the monthly audience over 50 million people. Combining Yandex’s recommendation technologies along with the professional content, Media Services offers its users various interesting entertainment options. We monetize Media Services through online advertising and transaction revenues, including music subscriptions and event tickets sales. Beginning with Q1 2018, we will report Media Services as a separate segment.

Media Services’s constituents:

· Yandex.Music is our music streaming service, offering users millions of tracks and facilitating new music discovery with its recommendation tools and Radio feature. Yandex.Music has a free web version and mobile app and is offered as both Yandex’s own service and as a white label product for mobile operators. According to AppAnnie, in 2017 Yandex.Music became the top non-game mobile app by revenue in Russia.

· KinoPoisk is the largest Russian language source for movies, TV series, celebrity content and entertainment news, providing users with critic and user reviews and ratings, personalized recommendations, local movie showtimes, ticketing, and many other services.KinoPoisk also features its own video platform, allowing users to watch movies online. Further expansion of our licenced content library and distribution of video platform is one of our strategic focuses.

· Yandex.Afisha (“playbill”) allows users to select entertainment from a wide variety of options. The service provides an opportunity to buy tickets to cinemas, theaters and concerts online. It incorporates personalized recommendations and is currently active in over 180 cities across Russia.

· Yandex.TV Program is a service providing users with an up to date schedule of broadcast, cable and digital TV channels as well as an option to view certain TV channels online.

Yandex Data Factory

Yandex Data Factory (YDF) is aimed at developing big data analytics solutions for companies in finance, retail, telecom, manufacturing, healthcare and other industries. Our YDF team consists of machine learning and data analytics experts who use data science to improve businesses’ operations, revenues and profitability.

Discovery Products

Yandex Zen is a personal recommendation service. Analyzing what a particular user reads on the internet, Zen selects news, videos, images, blog entries, and other internet postings that may be relevant to the user. The service uses Yandex's global search index and AI technology. Yandex.Zen is available on Yandex Home Page and Yandex search app, in addition to Yandex Browser and Yandex Launcher. In September 2017, we launched a standalone Zen app on Android.

38

In May 2017, we allowed publishers to create and distribute content exclusively through Yandex.Zen so they can create their own channels with text, video and advertisements and run experiments with mobile formats directly. Also, we gave publishers an ability to monetize their channels through online advertising and through users’ donations. To enable publishers to enrich their content and help increase user engagement, in October 2017 we launched a new publisher format available on mobile devices called “Narratives”, which is a set of screens combining text, video, images and GIFs that can be swiped through.

In 2017 Zen generated more traffic to third party websites than any social network in Russia. In December 2017 Zen reached 10 million daily active users.

Yandex Launcher is our take on the Android interface, allowing users to adapt their Android phones to fit their style and fill it with interesting content from all over the internet.

Search and Portal in Turkey

Yandex is also available in Turkey, providing users in this country with Yandex’s major products such as search, mail, maps, traffic, weather and browser. The main focus of our Turkish office is providing advertising services to local customers and promoting our core services, mainly search and geo‑informational services, for Turkish users.

Our Technology

Yandex is a technology company that pioneered machine learning, artificial intelligence and neural networks early on. This expertise uniquely positions us in the global technology arena, allows us to innovate in our local markets and to continuously improve our products and services based on complex, unique technologies that are not easily replicated.

Yandex distributed infrastructure

We seek to ensure the speed and reliability of our services regardless of the user’s location by operating our own Content Delivery Network (CDN) of points of presence in major cities throughout Russia and the other countries in which we operate. This network allows us to support reliable 24/7 operations, including server‑based computations, research and development work, and user and advertiser services. We use proprietary computer architecture to link these clusters of servers, as well as proprietary computational software that operates across these distributed servers, including software that enables us to deploy and monitor software across our systems. This allows us to use relatively inexpensive off‑the‑shelf servers as the foundation of our robust and effective systems for redundant, distributed data storage, retrieval and distributed calculations. Geographic distribution of our servers decreases the cost of internet usage for our users, increases the access speed for our services and increases the stability and dependability of our service offerings. This structure provides redundant fail‑safe capacity such that the failure of a single facility would not cause our websites to stop functioning.

Advertisers

Our advertisers include individuals and small, medium and large businesses throughout the countries in which we operate, as well as large multinationals. Small and medium‑size enterprises purchase the bulk of our performance‑based advertising. No particular advertiser accounted for more than 1.2% of our total revenues in 2015, 2016 or 2017.

Sales and Advertiser Support

We have an extensive sales and support infrastructure, with sales offices in a number of cities in Russia, as well as Lucerne, Switzerland; Newburyport, Massachusetts, USA; Istanbul, Turkey; Shanghai, China; and Almaty, Kazakhstan. We attract advertising customers through both online and offline sales channels.

The substantial majority of our advertisers use our automated Yandex.Direct service to establish accounts, create ads, target users and launch and manage their advertising campaigns. We provide email and telephone support for these customers. Our largest advertising clients are served by a dedicated sales team. These companies may request strategic support services, which include a dedicated accounts team, to help them set up and manage their campaigns.

39

Our sales team specialists are able to help advertisers with tasks such as selecting relevant keywords, creating effective ads and audience targeting, thus measuring and improving advertisers’ return on investment.

The Yandex ad network follows a similar model. Most of the websites in the network submit their applications through Yandex.Direct’s automated partner interface. Our direct sales force focuses on building relationships with our largest partners to help them get the most out of their relationship with us. We also have relationships with different advertising sales agencies placing online advertising. 

Marketing

We engage in significant marketing efforts directed first and foremost at internet users, as well as advertising agencies, advertisers and webmasters. Our marketing efforts are focused above all on delivering an optimal user experience with every Yandex product and service. We believe that satisfied users are the best and most credible advocates for our services. In order to improve user satisfaction and loyalty and to continue to use our products and services as marketing tools, we constantly experiment with and improve the design, technology and interface of these products and services. Although we believe that word of mouth is the best advertising strategy, we also view advertising campaigns in online and traditional media as an important element of our efforts to promote our brand, as well as key services. We also invest heavily into our separate business units, including E‑commerce, Taxi and Classifieds, to grow customer awareness, increase user base, increase usage in the existing markets and penetrate into other geographies.

Competition

We operate in a market characterized by rapid commercial and technological change, and we face significant competition in many aspects of our business. We currently operate principally in Russia, Belarus, Kazakhstan and Turkey. We face competition from global players such as Google and local players such as Mail.ru Group, both of which offer proprietary search and other services.

We consider Google to be our primary competitor. In addition to its search solutions, Google offers online advertising, information and other search services similar to ours, including services similar to Yandex.Direct and other. We expect that Google will continue to use its brand recognition, financial and engineering resources to compete with us. In 2013 we entered into a partnership with Mail.ru Group pursuant to which Mail.ru Group uses the Yandex.Direct advertising system to power paid search results on its properties. Mail.ru Group offers many communication services, including Russia’s most popular webmail, social networking and messenger services. We compete with Mail.ru for advertising budgets that flow to Mail.ru’s social networks.

The following table presents a comparison of Russian search market share, according to Yandex.Radar (a search traffic and browser usage analytics tool based on Yandex.Metrica data), based on search traffic generated:

	2015		2016		2017
Yandex	57.3	%	56.0	%	55.1	%
Google	34.5	%	37.1	%	39.6	%
Mail.ru	5.0	%	4.1	%	3.4	%

We also face competition from the Russian and international websites of Microsoft and other established companies and start‑ups that are developing search and online advertising technologies. We also compete with online advertising networks, such as Google and MyTarget, which direct online advertising on a number of popular Russian websites.

We believe that social networking sites, such as Facebook, Twitter, and Mail.ru Group’s Vkontakte, Odnoklassniki and My World services, will become significant competitors for online ad budgets. These sites derive a growing portion of their revenues from online advertising, and are experimenting with innovative ways of monetizing user traffic. In light of their very large audiences and the significant amount of proprietary information they can access and analyze regarding their users’ needs, interests and habits, we believe that they may be able to offer highly targeted advertising which could create increased competition for us. The popularity of such sites may also reflect a growing shift in the way in which people find information, get answers and buy products, which may result in increased competition for users.

40

In certain vertical areas, in particular those in which our business units operate, we compete with niche services, including e‑commerce, video search, online news aggregators and dictionaries, real estate and automobile services, and specialized search apps for mobile devices. Our Yandex.Taxi service competes with Gett as well as a number of regional offline players across Russia. In addition, although Yandex.Taxi and Uber operate as a joint venture in Russia and neighboring countries, our Taxi business may also compete with Uber in jurisdictions outside the scope of our joint venture territory. Our e‑commerce services face competition from a number of local players acting as both merchants and marketplaces, Avito, which acts as a marketplace for merchants and private individuals, Youla, and a number of international players popular with Russian users, especially those from China such as AliExpress. Our Classifieds services compete with Avito in most areas as well as a number of players present in specific industries such as CIAN in real estate and Drom.ru in automobile sales.Our food delivery business Yandex.EATs competes with Delivery Club, owned by Mail.ru.

We also face competition from other search and service providers in establishing relationships with device manufacturers, such as mobile and tablet computer makers, and access providers, such as internet service providers. Such companies have a significant degree of control over the distribution of products and services, including by offering or establishing exclusive arrangements for “default” search features or other services and bundling them with their offerings. Our users typically have direct relationships with these companies, and may be influenced by economic or other factors in deciding which search or other services to use.

Science and Education

Our team of specialists represents many scientific disciplines, including mathematics, data analysis, programming and linguistics. Besides working on products and technologies at Yandex, some of our experts teach, lecture and train students and young specialists.

We also run our own educational programs. The Yandex School of Data Analysis, offering free courses for university graduates and graduate students, has been running since 2007. The school trains specialists in data processing, data analysis and fact extraction in 5 Russian cities and in Minsk, Belarus. The school’s graduates create a global alumni network advancing machine learning in academia and private IT sector. Yandex also has schools for project managers, user interface developers, designers and other specialists in IT.

In 2016 with the support of regional governments and ministries overseeing education and IT, we launched a project to teach programming to school children called Yandex.Lyceum which is now offered in 19 cities in Russia and 2 cities in Kazakhstan.

We value education and are glad to open new educational opportunities supported with our technologies. In June 2017, Yandex partnered with Prosveshcheniye, known as Russia’s largest educational publisher, to develop a digital education platform for Russian schools. The pilot project was launched in schools in 5 regions.

In addition to educational services, Yandex and Coursera, the online education platform, launched several Specializations and Courses written by Yandex’s employees for people who are eager to expand their knowledge in a certain field of IT.

In October 2017, we introduced a new service called Yandex.Atlas, which provides students and their parents with information about the pass rates of Russian universities in previous years. The project is aimed to help children and their parents with choosing an appropriate university in accordance with their requirements and opportunities.

Yandex and the Higher School of Economics run the Faculty of Computer Science for which we created an educational programme. We also partner with other leading research centers and universities, including the Moscow Institute of Physics and Technology, Saint Petersburg State University and the Belarusian State University. We sponsor a number of school contests in computer programming, mathematics and linguistics, and run a programming competition, Yandex.Algorithm, on annual basis challenging competitive coders and advance the machine learning community across the world.

Russia’s largest technology conference, Yet Another Conference, which is organized by Yandex every year, gathers industry experts from all over the world. We also run scientific conferences on machine learning, as well as

41

seminars, lectures, workshops and master classes for those who wish to make or have already made a career in the technology industry.

Employees and Workplace Culture

We place a high value on technological innovation and compete aggressively for talent. We strive to hire the best computer scientists and engineers, as well as talented sales, marketing, financial and administrative staff. We seek to create a dynamic, fulfilling work environment with the best features of a “start‑up” atmosphere, encouraging equal participation, creativity, the exchange of ideas and teamwork.

Our total headcount increased from 6,271 at December 31, 2016 to 7,445 at December 31, 2017. As of December 31, 2017, we had 4,290 employees related to the product development cost category, 2,716 employees related to sales, general and administration, and 439 employees related to cost of revenues. 

Intellectual Property

We rely principally on a combination of trademark, copyright, related rights, patent and trade secret laws in Russia and other jurisdictions as well as confidentiality procedures and contractual provisions to protect our proprietary technology and our brand. We enter into confidentiality and patent assignment agreements with our employees and consultants and confidentiality agreements with other third parties, and we rigorously control access to our proprietary technology.

Our patent department is responsible for developing and implementing our group‑wide IP protection strategy in selected jurisdictions. We have filed more than 600 patent applications to date, of which more than 200 have resulted in issued patents. We also have internal procedures for invention disclosures, patent filings, patent acquisitions, freedom‑to‑operate analyses and patentability searches.

Yandex is a registered well‑known trademark in Russia for certain services (classes 35 and 38 under the International Classification of Goods and Services) among consumers of such services on the basis of intensive use. Under Russian law, the protection granted to well‑known trademarks is extended to non‑homogeneous goods and services if customers associate specific use of the designation by third parties with the rights holder and the rights holder’s legitimate interests are infringed. Yandex is also a registered trademark in Ukraine, the United States, the European Union and other countries under the Madrid Agreement and Protocol. We have other registered trademarks in Russia. We continue to file applications to register new trademarks and widen the country coverage of our existing trademarks. Most of the software used by our services or distributed by Yandex to our users is either developed by our employees or by independent contractors who transfer all rights to Yandex.

We enter into written license and use arrangements with providers of a significant portion of the content we offer. Our agreements with most of the news content providers in Russia are on “content‑for‑traffic” terms, pursuant to which we obtain access to news content for free in consideration of the user traffic that accesses the content providers’ websites through our search engine. We license or purchase other additional content. We do not knowingly include content on our websites that we do not have the legal right to include.

We do not own the content generated or posted by users on our websites. As with all websites that host user‑generated content, we are potentially liable for any intellectual property infringement committed by the creator of that content. If we receive a complaint from a party that user‑generated content on our websites infringes that party’s copyright or related rights, we examine the content in question. If we are unable to confirm the violation independently, we request a formal letter of complaint from the notifying party. We then contact the party that has posted the content, and give that person two options: either remove the content, or allow us to provide his or her personal details to the notifying party so that that party may defend its rights. In the event of any court decision in the matter, we comply with the decision. If the potentially offending party does not respond, we remove the content.

Facilities

Our principal operating subsidiary currently leases a total of approximately 60,000 square meters in a single location in central Moscow that serves as our group’s headquarters. We also lease additional office space of approximately 14,000 square meters of office space in a business center in central Moscow, which houses some of our

42

divisions. We or our operating subsidiaries also lease or own office space in a number of other cities in Russia. We also lease offices in Newburyport, Massachusetts; Istanbul, Turkey; Lucerne, Switzerland; Minsk, Belarus; Berlin, Germany; Schiphol, The Netherlands; Shanghai, China; Almaty, Kazakhstan, and other locations. We operate data centers in Moscow and other regions of Russia, as well as in Finland. We have points of presence in a number of cities in Russia and elsewhere. Taking into account the projected demand for our services, we continuously evaluate the capacity and locations of our data centers to determine the most cost‑effective manner of delivering reliable services to our users.

Government Regulation

We are subject to an extensive and constantly evolving legal framework in Russia and other jurisdictions applicable to the internet business. As explained in more detail below, there are also a significant number of additional laws and regulations currently being debated and considered for adoption in Russia and other countries where we operate which, in the event of adoption, might require us to make substantial adjustments to our business practices. Due to changing interpretations of laws and regulations, we could also be subject to laws and regulations to which we are not currently subject and which could materially affect our operations.  We have not summarized laws and regulations to which we do not believe we are currently subject.

Advertising Regulation

The principal Russian law governing advertising, including online advertising, is the Federal Law No. 38-FZ “On Advertising,” dated March 13, 2006 (as amended) (the “Russian Advertising Law”). The Russian Advertising Law prohibits advertisements for certain regulated products and services without the required certification, licensing or approval. For example, advertisements for products such as pharmaceuticals and medical equipment, food supplements and infant food, financial instruments or securities and financial services as well as incentive sweepstakes and advertisements aimed at minors and some other products and services must comply with specific requirements and must in certain cases be accompanied by certain required disclaimers. Additionally, Russian law contains certain prohibitions regarding the advertising of alcohol, tobacco and medical services. In addition, the distribution of advertisements over the internet (for example, by email) may require the prior express consent of recipients. In some cases, violation of these Russian laws can lead to civil action by third parties who suffer damages, or administrative penalties imposed by FAS. Further amendments to legislation regulating advertising may impact our ability to provide some of our services or limit the type of advertising we may offer.

We seek to comply with all advertising laws and regulations. At the same time, the application of the advertising laws, in particular in relation to products or services requiring certification, licensing or approval, can be ambiguous and inconsistent. The application of these laws in an unanticipated manner, or the failure of our compliance efforts, may expose us to substantial liability as distributors of advertising and may restrict our ability to provide some of our services.Other laws or interpretations of laws, including those of foreign jurisdictions, may also restrict advertising and negatively impact our business. For example, some French courts have interpreted French trademark laws in ways that would limit the ability of competitors to advertise in connection with generic keywords. Adoption of similar interpretations by Russian or other national courts may adversely affect our business. In addition, Russian law does not specifically regulate behavioral targeting in relation to advertising, which is a standard tool widely used in the online business. Any future interpretation of Russian law affecting the regulation of behavioral targeting could have a negative impact on our business.

Intellectual Property Regulation

In principle, the acquisition, protection and enforcement of intellectual property rights in Russia are addressed in line with international standards. In particular, literary, artistic and scientific works are subject to copyright protection without any registration and enjoy legal protection simply by virtue of being created in an objective form perceivable by third parties.

Mandatory registration with Rospatent is required for “hard IP” such as trademarks and patents (available in Russia for inventions, utility models and industrial designs) in order for the rights holder to acquire exclusive rights. Trademarks registered abroad under the Madrid Agreement and/or Madrid Protocol have the same legal protection in Russia as locally registered trademarks. 

Under Russian law, we have exclusive rights to trade secrets (know-how) only if we have complied with a legal requirement to introduce reasonable measures to maintain confidentiality of our trade secrets, which measures may be

43

burdensome and formalistic to implement. As we rely extensively in our operations on the protection afforded to trade secrets, we have implemented a set of measures required by Russian law in order to protect these trade secrets (know-how). However, there is a risk that our measures will be deemed insufficient and, as a result, we will fail to acquire rights to these trade secrets under Russian law.

One of the known problems and risks in Russian business practice relates to acquiring exclusive rights to works for hire and patentable results from employees. As a rule, the exclusive rights to works for hire and patentable results are assigned to the employer if the intellectual property is made during the course of employment.  However, there are often uncertainties and disputes around the scope of such assignments. In case of employment disputes, Russian courts are often inclined to follow an overly formalistic approach and may take a pro-employee position in the event of uncertainty in a dispute of this nature.

Nonetheless, under Russian law, subject to the risks outlined above, we are deemed to have acquired copyrights and rights to file patent applications with respect to works for hire and patentable results created by our employees during the course of their employment with us and within the scope of their job duties, and have the exclusive rights to their further use and disposal subject to compliance with the requirements of the Civil Code of Russia.

Liability of Online Service Providers

Laws relating to the liability of online service providers for the activities of their users and other third parties are still being developed in Russia and certain other countries in which we operate.

Russian law contains provisions aimed at establishing a framework for limitation of liability of online service providers for the information communicated by third parties over such providers’ networks. Substantial ambiguity remains in Russian law around the scope and protection of such limitation of liability.  In particular, there is little clarity on the limitation of liability with respect to types of online service providers other than providers transmitting information and hosting providers (such as those caching data or providing information location tools). Because the law has not been given detailed binding interpretation, our exposure to liability will depend significantly on the interpretation of these provisions by the courts and officials.

The Russian Civil Code also imposes strict liability for infringement of intellectual property rights if such infringement is committed in connection with business activities. It is unclear how these provisions apply to online service providers.

Russian law establishes a system for the blocking of websites on the internet that make available specific categories of illegal information related to child pornography, suicide or drug use as well as other restricted information. Current law also permits the blocking of websites for violation of data protection, copyright and related rights. The procedure for deleting such information is complex and strictly enforced and the failure to follow such procedures leads to the blocking of the applicable website by all Russian internet service providers and telecommunication service operators.

Other legislation is currently in place in Russia that allows blocking of websites that contain extremist information (including containing calls for mass rioting, extremist activity and participation in mass assemblies conducted in violation of established procedure) at the request of certain governmental authorities without prior notification. Only a subsequent post-blocking notification to the relevant website owner or hosting provider is required. The categories of illegal information to which access can be restricted may be interpreted broadly or be expanded by government authorities depending on circumstances. We may find ourselves subject to such blocking if government authorities interpret information provided by our services as violating these rules and we may be unable to prevent this blocking of our services.

Russian law also restricts the circulation of certain identified categories of publicly available and distributed information that may be harmful for minors. In particular, there is a requirement to take administrative and technical measures to prevent dissemination of restricted information. In addition, the circulation of information products must be accompanied by a relevant mark identifying the age restriction category of information.

This legislation, as well any similar additional regulations, and the interpretation of such legislation and regulations may impose new requirements on us and our operations and lead to material legal liability, which can be difficult to foresee or limit. See “Risk Factors—We may be held liable for information or content displayed on, retrieved by or linked to on our websites and mobile applications, or distributed by our users; or we may be required to block certain content or access to our websites could be restricted; any of which could harm our reputation and business.”

Laws and Regulations Applicable to Yandex.Money

Our Yandex.Money joint venture with Sberbank is subject to laws and regulations specifically applicable to electronic payments and encrypted information. Under the regulations governing electronic payment systems, payments with digital money fall into the sphere of banking activities and such payments are regarded as a special transaction entered into without the need to open an account. Such transactions, however, have to be performed by a credit organization supervised by the Central Bank of Russia. To comply with this law, our Yandex.Money joint venture established a non-banking credit organization subsidiary, which obtained the required license from the Central Bank of Russia. All necessary contractual obligations of PS Yandex.Money LLC have been transferred to its non-banking credit organization subsidiary.

Under Russian law, a variety of activities related to encryption require a special permit (license) granted by the Federal Security Service (the “FSS”) subject to the applicant’s continued compliance with a number of licensing requirements, including the requirement to use only certified encryption means and equipment and to ensure timely extension of such certification when its terms expire.

Our Yandex.Money joint venture with Sberbank uses encryption algorithms for the protection of transfers performed by its customers and may be required to obtain additional licenses for their use. The requirements for the grant and maintenance of licenses for the use of encryption algorithms are very broad and unclear, leaving the regulator with much discretion in applying and enforcing the applicable laws. See also “Risk Factors—Because the range of the services we provide is increasing and the legal framework governing internet services and e-commerce in our markets is evolving, we may be required to obtain additional licenses, permits or registrations or comply with other requirements, which may be costly or may limit our flexibility to run our business.”

As a holder of an encryption license, Yandex.Money is subject to Russia’s Strategic Companies Law which restricts the acquisition of voting shares or participation interests and establishment of control by foreign legal entities and individuals, as well as states, international organizations and entities controlled by them, with respect to business entities with strategic importance. According to the amendments to this law and to the Foreign Investment Law that came into force in July 2017, Russian citizens who also have any other citizenship as well as Russian companies that are controlled by foreign investors are now also considered to be foreign investors. In addition, the Chairman of the Government Commission on Control over Foreign Investments in the Russian Federation is now granted the right to decide that approval is required with respect to any transaction by any foreign investor with regard to any Russian companyfor the purpose of ensuring national defense and state security. Upon receipt of such a decision from the Government Commission, FAS has three days to notify the foreign investor about the need to receive approval for a prospective transaction. Furthermore, the Government Commission may now impose additional obligations on foreign investors outside of the limited list provided in Article 12 of the Strategic Investments Law as a condition of a transaction approval.

While we are currently in compliance with the Strategic Companies Law, the Strategic Companies Law may prevent our Yandex.Money joint venture from pursuing strategic transactions which could further grow the Yandex.Money business.

Mass Media Regulation

Russian law requires certain parties that disseminate news and similar mass communications and information to be registered with the appropriate Russian governmental body, Roscomnadzor, and to comply with restrictions regarding the distributed content. The law currently permits electronic network publications (websites) to register as mass media. As registration under this amendment is voluntary, we elected not to register our online properties as mass media. See “Risk Factors—Because the range of the services we provide is increasing and the legal framework governing internet services and e-commerce in our markets is evolving, we may be required to obtain additional licenses, permits or registrations or comply with other requirements, which may be costly or may limit our flexibility to run our business.”

Since 2016, Russian law imposes a limit on non-Russian ownership and control, direct or indirect, of Russian

45

mass media of no more than 20%. Accordingly, if our core business were to be required to register as a mass media, it would have a material impact on the ownership structure of our business and could materially adversely affect the value of our Class A shares. See also “Risk Factors—Existing restrictions on foreign ownership may prevent a takeover of our company by a non-Russian party. If the Russian government were to apply existing limitations on foreign ownership to our business, or specifically impose limitations on foreign ownership of internet businesses in Russia, it could materially adversely affect our group and the value of our Class A shares.”

Privacy and Personal Data Protection Regulation

We are subject to Russian and foreign laws regarding privacy and the protection of our users’ personal data. We publish on our websites our privacy policies and practices concerning the use, processing, storage and disclosure of user data. Any failure by us to comply with our privacy policies as well as Russian or other applicable laws and regulations relating to privacy and the protection of user data may result in proceedings against us by governmental authorities, individuals or other third parties, which may adversely impact our business. In addition, the adoption and interpretation of data protection laws, and their application to internet operations, are often unclear, difficult to predict and are in a constant state of development. Although we believe that we comply with all current requirements, these laws could in the future be interpreted and applied in a manner that is inconsistent with current practice. For instance, in May 2014 the Court of Justice of the European Union established that an operator of a search engine can be obligated to remove from the list of search results links to webpages containing inaccurate or outdated information related to an individual. Russian personal data laws have been amended, granting a similar right to Russian citizens, who from January 2016 have been able to apply for the removal of search results that link to inaccurate or irrelevant information about them. In addition, in May, 2018 the General Data Protection Regulation (the GDPR) comes into force in the EU and its provisions may contradict national data privacy regulations in some countries where we operate. In those cases we will have to compare the liability under the GDPR and national laws to decide, with which regulation to comply.

Russian data protection laws provide that an individual must freely consent to the production of her/his personal data. Such consent must be concrete, informed and conscious, and may be provided in any form evidencing the fact that consent has been provided, unless otherwise established by federal law, which requires that it be made in writing, signed by digital electronic signature or evidenced in a similar manner prescribed by laws and regulations.

We, like our peers, seek this consent from our users by asking them to click on a button or select a check-box in appropriate circumstances prior to commencement of the account registration process indicating the user’s consent to our collection, use, storage and processing of personal data. Furthermore, most of our services do not require the creation of an account prior to their use and we collect only limited information in these circumstances. In particular, we place cookies and use other widespread technologies that assist us in improving user experience of our products and services and ultimately benefit both our users and advertisers to the extent that we use a certain part of this collected information for behavioral targeting of advertising. No clear legislative guidelines have been provided addressing whether our practices are compliant with the requirements of the data protection legislation in Russia and abroad. There is a risk that such laws may be interpreted and applied in a manner that is not consistent with our current data protection practices. Complying with various regulations in this area may cause us to incur additional costs or to change our business practices. Further, any failure by us to protect our users’ privacy and data may result in a decrease of user confidence in our services, and may ultimately result in a loss of users, which would adversely affect our business.

Russian legislation also regulates “organizers of information distribution”. Organizers of information distribution must retain a broad range of data relating to and generated by users for a period of time, and provide such data to security and investigation authorities at their request. Organizers of information distribution that use encryption when delivering or processing electronic messages have to provide the security authorities with information necessary for decoding the delivered or processed messages. If an organizer of information distribution fails to comply with the above requirements, the Russian authorities can prescribe the blocking of access to the services of such organizer of information distribution.

Russian personal data law also requires that companies store all personal data of Russian users only in databases located inside Russia. Although we have data centers located in Russia, this law could limit our flexibility in managing our operations globally. Failure to comply with applicable data protection legislation may lead to the restriction of access to our services. For example, in 2016 a Russian court ordered the blocking of access to a popular social networking website for violation of data protection legislation.

Licenses for the Provision of Communication Services

46

Entities that provide certain telecommunication services for a fee are required under Russian law to obtain a “telematics” license from Roscomnadzor. In order to increase our range of services and diversify our business we obtained the telematics licenses necessary for the provision of certain of our new services in Russia. However, we generally do not charge a fee for the online services we provide to our users and therefore, believe that we are not required to hold a telematics license for provision of these services. We do, however, generate revenue from ads directed to our users. As a result, it is possible that a Russian court or government agency may construe our advertising revenue as a fee and determine that we are required to hold a telematics license for such services, which would require us to apply for and comply with the terms of any such license.

Additionally, we may in the future offer user services for a fee, which could require us to comply with the licensing requirements described above.

Antimonopoly Regulation

Russian law grants to FAS as the antimonopoly regulator wide powers and authorities to maintain competition in the market, including approval or monitoring of mergers and acquisitions, establishment of rules of conduct for market players occupying dominant positions, prosecution of any wrongful abuse of a dominant position, and the prevention of cartels and other anti-competitive agreements or practices. The regulator may impose significant administrative fines (up to 15% of the annual revenue derived in the market where the violation occurred) on market players that abuse their dominant position or otherwise restrict competition, and is entitled to challenge contracts, agreements or transactions that are in violation of the antimonopoly regulation. We may be considered to possess a substantial market share in the online advertising market; however, we are not recognized by the regulator as occupying a dominant position in any market. However, we understand that the regulator from time to time focuses on internet services and could in the future recognize online advertising as a separate market, and could identify dominant players and impose conduct limitations and other restrictions.

In addition, FAS is currently developing the “fifth antimonopoly package” – the amendments to the existing antimonopoly legislation in the sphere of digital markets and IP. The new legislation may have a far-reaching impact on our business, which is difficult to estimate at present time.

Taxation Regulation

Taxation of legal entities and individuals in Russia is regulated primarily by the Tax Code of the Russian Federation. The scope and application of the Tax Code is elaborated by numerous regulations and clarifications from the Ministry of Finance of Russia and by the Federal Tax Service, which enforces the tax laws. Russian tax law and procedures are still not fully developed and local divisions of the Federal Tax Service have considerable autonomy in tax law interpretation and often interpret tax rules inconsistently. Also, there is extensive court practice on the construction of the Code’s provisions, which can sometimes be unpredictable or even contradictory. Both the substantive provisions of the Russian tax law and the interpretation and application of those provisions by the Russian tax authorities and by Russian courts may be subject to rapid and unpredictable change. See “Risk Factors—Changes in the tax systems of Russia and other countries in which we operate, as well as unpredictable or unforeseen application of existing rules, may materially adversely affect our business, financial condition and results of operations.” In addition, there is an uncertainty regarding the taxation of our service Yandex.Music. The business activity of this service can be either determined as providing services (which falls under VAT taxation) or licensing (which is exempted from VAT taxation).

Securities Regulation

Our Class A ordinary shares are currently listed on the NASDAQ Global Select Market and in June 2014 were admitted to trading on Moscow Exchange; therefore we are required to comply with specific Russian regulation concerning information disclosure, insider trading and certain other requirements as may be applied to foreign issuers in Russia.

Applicability of Other Regulations

Because our services are accessible to Russian-language speakers worldwide and are becoming increasingly available to other users globally, certain foreign jurisdictions, including those in which we have not established a local office, employees or infrastructure, may require us to comply with their local laws.

Item 5.  Operating and Financial Review and Prospects.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with the “Selected Consolidated Financial Information” section of this Annual Report and our consolidated financial statements and related notes appearing elsewhere in this Annual Report. In addition to historical information, this discussion contains forward‑looking statements based on our current expectations that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward‑looking statements as a result of various factors, including those set forth in the “Risk Factors” and “Forward‑Looking Statements” sections and elsewhere in this Annual Report.

Overview

We are one of the largest European internet companies and the leading search provider in Russia. Our principal constituencies are:

· Users.  We provide our users with advanced search capabilities and an extensive range of online services that enable them to find relevant, objective information quickly and easily, as well as communicate, connect and shop over the internet.

· Advertisers.  Our online advertising platform allows advertisers to reach a large audience of users in their markets and deliver cost‑effective online advertising. With Yandex.Direct, our auction‑based advertising platform, advertisers can promote their products and services through relevant ads targeted to a particular user query, the content of a website or webpage being viewed, or user behavior or characteristics. Our Yandex.Market service allows merchants to advertise their goods and services either using a traditional CPC advertising model or using a CPA model that charges advertisers only when it delivers a paying customer.

· Yandex ad network partners.  We have relationships with a large number of third‑party websites, which we refer to as the Yandex ad network. In addition to serving ads on our own websites, we also serve ads on our network partners’ websites and share the fees generated by these ads with our partners, providing an important revenue stream for them.

Our yandex.ru website first began generating revenue in 1998. We became profitable in 2003 and have been profitable every year since then.

Advertising revenues accounted for 97.4%, 95.6% and 93.0% of our total revenues in 2015, 2016 and 2017, respectively. Our advertising revenues consist of fees charged to advertisers for serving online ads on our websites and those of our partners in the Yandex ad network. We place the significant majority of our performance‑based ads through Yandex.Direct and the remainder through Yandex.Market, our e‑commerce gateway service. We sell approximately half of our performance-based ads on a prepaid basis. Our Yandex.Direct advertisers pay us on a cost‑per‑click (CPC) basis, which means that we recognize revenue only when a user clicks on one of our advertisers’ ads. Our brand advertising is generally sold on a cost‑per‑thousand (CPM) impressions basis. For these ads, we recognize as revenue the fees charged to advertisers when their ads are displayed. Our Yandex.Market service is priced on a CPC basis, similar to Yandex.Direct. Yandex.Market also operates on a take-rate-based model. In September 2016 we started to actively switch certain goods’ categories in several regions to the take-rate-based model as we consider it beneficial to both merchants and consumers.

We recognize our advertising revenues net of value added tax (currently 18.0% in Russia) and sales commissions and bonuses. Although the major part of our revenues is generated by direct sales to our advertisers, a significant portion of our advertising sales are sold through media agencies. We recognize revenues from those advertising sales net of the commissions and bonuses paid to these agencies.

48

We benefit from a large and diverse base of advertisers. Our advertisers include individuals and small, medium and large enterprises across Russia and the other countries in which we operate, as well as large multinational corporations. No individual advertiser accounted for more than 1.2% of our total revenues in 2015, 2016 or 2017. On a geographical basis, we generated more than 91% of our total revenues in each of 2015, 2016 and 2017 from advertisers and other customers with billing addresses in Russia, including the Russian offices of large multinational advertisers.

We serve ads both on our own websites and on the websites of our partners in the Yandex ad network. For performance‑based ads served on the websites of our partners in the Yandex ad network, we recognize as revenue the fees paid to us by advertisers each time a user clicks on one of their performance‑based ads or, for those advertisers paying for brand ads on a CPM basis, as their ads are displayed. We pay our partners in the Yandex ad network fees for serving our advertisers’ ads on their websites. These fees are primarily based on revenue‑sharing arrangements. As such, the fees paid to our partners in the Yandex ad network are calculated as a percentage of the revenues we earn by serving ads on partners’ websites. We account for the fees we pay to our partners in the Yandex ad network as traffic acquisition costs, a component of cost of revenues. Since we launched our Yandex ad network in 2006, these costs annually have, in aggregate, amounted to more than one‑half of the revenues we have earned from serving ads on the Yandex ad network and we expect them to continue to do so in the foreseeable future. Yandex ad network partners do not pay us any fees associated with our serving ads on their websites.

Our agreements with our partners in the Yandex ad network generally have an indefinite term but may be terminated by either party at will with no termination fees. Agreements with larger partners in the Yandex ad network are individually negotiated and vary in duration but typically renew automatically. In 2015, 2016 and 2017, none of our ad network partners accounted for more than 10% of our total revenues. In 2017, Mail.ru Group continued to be our most significant ad network partner.

We believe the most significant factors that influence our ability to continue to increase our advertising revenues include the following:

· the level of internet penetration and usage in Russia and the other markets in which we operate;

· the absolute and relative level of traffic on our own websites and those of our partners in the Yandex ad network;

· the relevance, objectivity and quality of our search results and the quality of our other services and of the Yandex ad network;

· our search market share, including on mobile devices, with a larger market share allowing us to better monetize our users’ search activity and attract and retain advertisers, as well as partners in our Yandex ad network;

· the demand for online advertising in Russia and the other markets in which we operate, particularly among small and medium‑size businesses;

· our ability to effectively monetize traffic generated by our websites and those of the Yandex ad network partners, including through improvements to our advanced auction and advertising placement system, while maintaining an attractive return on investment for our advertisers; and

· our ability to effectively monetize mobile search where the number of search queries is growing more quickly than on desktops.

49

Segments

Starting 2015, we revised our organizational structure, separating several focus areas into product lines and geographies. As a result, our businesses are now organized in the following operating segments:

· Search and Portal, which includes all services offered in Russia,Belarus and Kazakhstan (and, for periods prior to the imposition of sanctions on Yandex by the government of Ukraine in May 2017, all our services offered in Ukraine), other than those described below;

· E‑commerce (including the Yandex.Market service);

· Taxi (including the Yandex.Taxi service, as well as Yandex.EATs, our food delivery business, which consists of FoodFox, acquired in December 2017);

· Classifieds (including Auto.ru, Yandex.Realty, Yandex.Jobs and Yandex.Travel); and

· Experimental businesses, where we aim to prove new business models. These include:

· Media Services (including KinoPoisk, Yandex.Music, Yandex.Afisha and Yandex.TV program);

· Yandex Data Factory;

· Discovery Services (including Yandex Zen and Yandex Launcher); and

· Search and Portal in Turkey.

Key Trends Impacting Our Results of Operations

Although the Russian economy stabilized to some extent in 2017, our results of operations have been impacted in recent periods by the macroeconomic environment in Russia, which has negatively affected our rate of revenue growth and our operating margins. The depreciation of the Russian ruble in 2015 increased the ruble amount of our U.S. dollar‑denominated expenses, including the rent on our Moscow headquarters and the acquisition of servers and networking equipment, and has generally increased the rate of inflation in Russia. In addition to the impact of the current macroeconomic environment, the trends described below are key drivers of our results of operations.

Our business and revenues have grown rapidly since inception, and the effectiveness of performance‑based advertising as a medium has contributed to the rapid growth of our business. Advertising spending continues to shift from offline to online as the internet evolves, and we expect that our business will continue to grow. However, we expect that our revenue growth rate will continue to decline over time as a result of a number of factors, including challenges in maintaining our growth rate as our revenues increase to higher levels, increasing competition, particularly on mobile devices, changes in the nature of queries, the evolution of the overall online advertising market and the declining rate of growth in internet users in Russia as overall internet penetration increases.

Our operating margins, representing our income from operations as a percentage of revenues, may fluctuate in the future depending on the percentage of our advertising revenues that we derive from the Yandex ad network compared with our own websites. The operating margin we realize on revenues generated from the websites of our partners in the Yandex ad network is significantly lower than the operating margin generated from our own websites. The percentage of our advertising revenues derived from the Yandex ad network increased from 26.0% in 2015 to 27.1% in 2016 and decreased to 25.5% in 2017. We currently expect that the portion of our advertising revenues derived from the Yandex ad network will remain roughly flat in 2018. The margin we earn, on average, on revenue generated from the Yandex ad network could decrease in the future if we are required to share with our partners a greater percentage of the advertising fees generated through their websites.

Growth in mobile search may also have an impact on our operating margins. The number of search queries from mobile devices, including smartphones and tablets is growing more quickly than desktop queries. Queries from mobile devices still, however, represented only 36.2% of our total search queries and 29.0% of our search revenues for

50

the year ended December 31, 2017. To date, growth in mobile usage has not had a material impact on our pricing, revenues or operating margins; however, we have seen some evidence that this growth may exert modest downward pressure on our revenues and operating margins in the future.

Recent and future capital expenditures may also put pressure on our operating margins. Our capital expenditures decreased from RUB 13,045 million in 2015 to RUB 9,625 million in 2016, and increased to RUB 12,389 million in 2017. We spent approximately 81% of our total capital expenditures in 2017 on servers and data center expansion to support growth in our current operations. Our depreciation and amortization expense slightly decreased as a percentage of revenues from 13.0% in 2015 to 12.7% in 2016, and continued decreasing to 11.9% in 2017. We currently expect our capital expenditures in 2018 to be in mid-teens as a percentage of revenues. However, in case we consider any new project, which may require additional capital expenditures, our capital expenditures may increase as a percentage of our revenues in 2018.

To support further brand enhancement and respond to competitive pressures, we spent larger amounts in 2016 and 2017 on advertising and marketing than we have spent historically, both in absolute terms and as a percentage of revenue. A significant portion of our advertising and marketing expense in 2016 and 2017 relates to our efforts to promote primarily our Yandex.Taxi and our Search services, and to support our brand in Russia and the other markets in which we operate. In 2017 Yandex.Taxi added 97 cities with 100,000+ population and 38 cities with population of 50,000+. As of December 2017, the service was available in 167 cities with 100,000+ population, and in 56 cities with population of 50,000+ across Russia, Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan and Moldova. Previously Yandex.Taxi reported that the service was operating in 46 cities across Russia, Georgia, Armenia, Kazakhstan, Belarus and Ukraine as of December 31, 2016, which primarily reflected the number of cities, where the number of rides exceeded 1,000 rides a week. We expect to continue to invest significantly in advertising and marketing. We currently expect our overall advertising and marketing costs in 2018 to remain roughly stable as a percentage of revenues in comparison to 2017 due to continuing investment to promote our services. This spending will not significantly impact our operating margin rate. However, we expect our operating margin to decrease as a percentage of revenues in the near term as a result of increasing share of business units as a percentage of total revenues, operating margins of which are lower compared with our core business.  

In Turkey we provide users in this country with Yandex’s major products such as search, mail, maps, traffic, weather and browser. The main focus of our Turkish office is providing advertising services to local customers and promoting our core services, mainly search and geo informational services.

Our revenues are impacted by seasonal fluctuations in internet usage and in advertising expenditures. Internet usage and advertising expenditures generally slow down during the months when there are extended Russian public holidays and vacations, and are significantly higher in the fourth quarter of each year. Moreover, expenditures by advertisers tend to be cyclical, reflecting overall economic conditions, retail patterns and advertising budgeting and buying patterns.

Inflation in Russia has also impacted our results of operations and may continue to do so. According to the Russian Federal State Statistics Service, Rosstat, the consumer price index in Russia increased by 12.9% and 5.4% in 2015 and 2016, respectively, and by 2.5% in 2017. The lower annual rate of inflation in 2016 and 2017 reflected the appreciation of the Russian ruble. We can provide no assurance that the annual rate of inflation will not increase significantly in 2018. Higher rates of inflation may accelerate increases in our operating expenses and capital expenditures and reduce the value and purchasing power of our ruble‑denominated assets, such as cash, cash equivalents and term deposits.

Changes in the value of the U.S. dollar compared with the Russian ruble can also negatively affect our results of operations. See “Quantitative and Qualitative Disclosures About Market Risk—Foreign Currency Exchange Risk.”

Recent Acquisitions

RosTaxi

In January 2015, we bought the assets and assumed the liabilities of the RosTaxi (“RosTaxi”) business, which operates a taxi fleet management application. The agreement provides for cash consideration of up to RUB 500 million, including a deferred payment of up to RUB 380 million, subject to successful technical integration and client base

51

transition, and contingent consideration of up to RUB 500 million payable in our ordinary shares on the third anniversary of the closing, depending on the number of qualifying taxi trips. During 2015, 2016, 2017 and in January 2018 deferred payments in the amount of RUB 50, RUB 65, RUB 195 and RUB 70 million, respectively, were paid. Contingent consideration depending on the number of qualifying taxi trips has been settled in full in February, 2018.

Agnitum

In December 2015, we completed the acquisition of assets and assumption of liabilities of Agnitum Ltd (“Agnitum”), an antivirus protection developer, for cash consideration of RUB 120 million and a deferred payment of up to RUB 80 million including additional payments subject to the attainment of certain implementation and integration milestones of up to RUB 60 million payable in cash and up to RUB 20 million to be granted in restricted share units.  A deferred payment in the amount of RUB 60 million was paid in cash in 2016.

We did not complete any business combinations in 2016.

Shkulev

In June 2017, we completed the acquisition of assets and assumption of liabilities of Hearst Shkulev Digital LLC (“Shkulev”),one of the biggest regional auto classifieds with the leading position in Sverdlovsk and Chelyabinsk regions of the Russian Federation, for a cash consideration of RUB 401 million, including a contingent consideration of RUB 52 million, subject to successful technical integration and client base transition.

FoodFox

In December 2017, we completed the acquisition of a 100% ownership interest in Deloam Management Limited and its subsidiary (“FoodFox”). Foodfox is one of the leading food delivery operators in Moscow. The primary purpose of the acquisition of FoodFox was to enlarge the range of services provided by us. The fair value of consideration transferred totaled RUB 595 million and consisted of cash consideration of RUB 541 million and deferred consideration of RUB 54 million. The deferred consideration arrangement requires the Company to pay the additional cash consideration to FoodFox’s former shareholders and convertible debt holders, when certain legal conditions are being met within one-year period.

Other Acquisition in 2017

During the year ended December 31, 2017, we completed another acquisition for total consideration of approximately RUB 66 million.

Transaction with Uber

In February 2018, we and Uber International C.V. have completed the merger of Yandex.Taxi Holding B.V. and its subsidiaries and several Uber legal entities into a new private limited liability company MLU B.V., incorporated under the laws of the Netherlands. We and Uber have each contributed legal entities related to ride-sharing and food delivery businesses in Russia, Kazakhstan, Azerbaijan, Armenia, Belarus, Georgia,  Kyrgyzstan and Moldova, and $100.0 million (RUB 5,722 million as of the date of acquisition) and $225.0 million (RUB million 12,874 as of the date of acquisition) in cash, respectively.

A further description of the acquisitions and their accounting implications can be found in Notes 4 and 18 of our audited consolidated financial statements included elsewhere in this Annual Report.

Our consolidated operating margin slightly increased from 16.0% in 2015 to 16.9% in 2016 and decreased to 13.9% in 2017. The decrease in 2017 compared with 2016 was primarily due to an increase in marketing and advertising expenses as a percentage of our total revenues, reflecting our efforts to promote our Yandex.Taxi and our Search services, and to support our brand in Russia and the other markets in which we operate. The slight increase in 2016 compared with 2015 was primarily due to a decrease in traffic acquisition costs paid to our partners in the Yandex ad network as a percentage of our total revenues as well as to a decrease in rent expenses attributable to our Moscow headquarters, which is U.S. dollar‑denominated, reflecting the Russian ruble appreciation, as well as absence of goodwill impairment recorded in 2016: partly offset by an increase in marketing and advertising expenses as a percentage of our total revenues, reflecting our efforts to promote our Yandex.Taxi, Yandex.Market and Yandex Browser and to support our brand in Russia and the other markets in which we operate.

Revenues

The following table presents our consolidated revenues, by source, in absolute terms and as a percentage of total revenues for the periods presented:

	Year ended December 31,
	2015			2016			2017
	RUB	% of Revenues		RUB	% of Revenues		RUB	% of Revenues
	(in millions of RUB, except percentages)
Advertising revenues(1):
Yandex websites	43,099	72.1	%	52,888	69.7	%	65,149	69.3	%
Yandex ad network websites	15,111	25.3		19,691	25.9		22,251	23.7
Total advertising revenues	58,210	97.4		72,579	95.6		87,400	93.0
Other revenues	1,582	2.6		3,346	4.4		6,654	7.0
Total revenues	59,792	100.0	%	75,925	100.0	%	94,054	100.0	%

(1) We record revenue net of VAT, sales agency commissions and bonuses and discounts. Because it is impractical to track commissions, bonuses and discounts for advertising revenues generated on our own websites and on those of our partners in the Yandex ad network separately, we have allocated commissions, bonuses and discounts between our own websites and those of our partners in the Yandex ad network proportionally to their respective revenue contributions.

54

Advertising revenues.  Total advertising revenues increased by RUB 14,821 million, or 20.4%, from 2016 to 2017 and by RUB 14,369 million, or 24.7%, from 2015 to 2016. Advertising revenue growth over the periods under review resulted primarily from growth in sales of performance‑based online ads, driven by an increase in the number of paid clicks and an increase in average cost‑per‑click paid by our advertisers. We do not expect the rate of advertising revenue growth in 2018 to be higher than in 2017.

Paid clicks on our own websites together with those of our Yandex ad network partners increased 9% from 2016 to 2017 and 14% from 2015 to 2016. The average cost‑per‑click on our own websites together with those of our partners in the Yandex ad network increased 10% from 2016 to 2017 and 10% from 2015 to 2016.

During the periods under review, the year‑over‑year rates of change in paid clicks and average cost‑per‑click on a quarterly basis were as follows:

	Year-over-year	Year-over-year
	growth in paid	growth in
Quarter	сlicks, %	cost-per-click, %
First Quarter 2015	12	2
Second Quarter 2015	12	1
Third Quarter 2015	15	3
Fourth Quarter 2015	10	12
First Quarter 2016	18	12
Second Quarter 2016	13	14
Third Quarter 2016	12	10
Fourth Quarter 2016	12	8
First Quarter 2017	12	10
Second Quarter 2017	10	9
Third Quarter 2017	6	12
Fourth Quarter 2017	10	9

The rate of change in paid clicks and average cost‑per‑click, and their correlation with the rate of increase in our revenues, may fluctuate from period to period based on such factors as seasonality, advertiser competition for keywords, our ability to launch enhanced advertising products that seek to deliver increasingly targeted ads, the fees advertisers are willing to pay based on how they manage their advertising costs, and general economic conditions.

Other revenues.  Other revenues principally represent commissions for providing ride-sharing services related to our Yandex.Taxi service and Music subscription fee. For ride-sharing services provided to individual transportation services users, we are not a primary obligor and report only Yandex.Taxi’s commission fees as revenue. For services provided to corporate transportation services clients we act as the primary obligor and revenue and related costs are recorded on a gross basis. Other revenues increased by RUB 3,308 million or 98.9% from 2016 to 2017 and by RUB 1,764 million or 111.5% from 2015 to 2016. Other revenues doubled in each of the periods under review due to the development of paid non‑advertising services, particularly, our Yandex.Taxi service.

Revenues by reportable segment.  Our revenues attributable to the Search and Portal segment increased by RUB 14,719 million, or 21.3%, from 2016 to 2017 and by RUB 13,351 million, or 23.9%, from 2015 to 2016. The growth in this segment’s revenues is in line with the growth in our overall advertising revenues. Search and Portal revenues accounted for approximately 89.3% of total revenues in 2017, compared with 91.2% in 2016 and 93.5% in 2015.

Our revenues attributable to the E‑commerce segment increased by RUB 250 million, or 5.3%, from 2016 to 2017 and by RUB 1,318 million, or 38.8%, from 2015 to 2016. E‑commerce revenues accounted for approximately 5.3% of total revenues in 2017, compared with 6.2% in 2016 and 5.7% in 2015. The decrease of this segment’s share of total revenues in 2017 compared with 2016 and 2015 is primarily due to higher revenue growth in other reportable segments and decrease of advertising and marketing spend in E-commerce in 2017.

Our revenues attributable to the Classifieds segment increased by RUB 778 million, or 59.7%, from 2016 to 2017 and by RUB 410 million, or 45.9%, from 2015 to 2016. Classifieds revenues accounted for approximately 2.2% of total revenues in 2017, compared with 1.7% in 2016 and 1.5% in 2015. The increase of this segment’s share of total

55

revenues in 2017 compared to 2016 is primarily due to rapid growth in its mature markets as well as in the regions, supported by our increased marketing spend in Classifieds in 2017.

Our revenues attributable to the Taxi segment increased by RUB 2,578 million, or 111.5%, from 2016 to 2017 and by RUB 1,329 million, or 135.1%, from 2015 to 2016. Taxi revenues accounted for approximately 5.2% of total revenues in 2017, compared with 3.0% in 2016 and 1.6% in 2015. The increase of this segment’s share of total revenues in 2016 and 2017 is primarily due to robust growth in the number of rides across our territories driven by aggressive investments in our existing markets as well as in geographical expansion. 

Our revenues attributable to the Experiments category increased by RUB 828 million, or 99.8%, from 2016 to 2017 and by RUB 389 million, or 88.2%, from 2015 to 2016. Media Services represent the bulk of the Experiments revenue line and were the main driver for the revenue growth. Experiments revenues were primarily related to Media Services and increased to approximately 1.8% of total revenues in 2017, compared with 0.7% and 1.1% in 2015 and 2016 accordingly.

Operating Costs and Expenses

Our operating costs and expenses consist of cost of revenues; product development expenses; sales, general and administrative expenses; depreciation and amortization expense; and goodwill impairment. In addition to the reasons discussed below with respect to each category, we generally expect our total operating costs and expenses to increase in absolute terms and as a percentage of revenues in the near term; see “—Key Trends Impacting Our Results of Operations”.

Cost of revenues.  Cost of revenues consists primarily of traffic acquisition costs. Traffic acquisition costs are the amounts paid to our partners in the Yandex ad network for serving our online ads on their websites and to our partners who distribute our products or otherwise direct search queries to our websites. These amounts are primarily based on revenue‑sharing arrangements. Some of our distribution partners are compensated on the basis of the number of installations of Yandex browser or search bars and applications.

The agreements with our distribution partners provide for payment of fees to them on a non‑refundable basis following the period in which the distribution fees are earned. We do not have a standard term or termination provision that applies to agreements with our distribution partners. Our largest distribution partner since 2012, Opera, accounted in aggregate for 23% of our distribution costs in 2017, and 24% and 26% in 2015 and 2016 accordingly. The Opera agreement also provides for a 12‑month “revenue tail” period should that agreement be terminated.

Cost of revenues also includes the expenses associated with the operation of our data centers, including related personnel costs, rent, utilities and telecommunications bandwidth costs, as well as content acquisition costs.

The following table presents the primary components of our cost of revenues in absolute terms and as a percentage of revenues for the periods presented:

	Year ended December 31,
	2015		2016		2017
	(in millions of RUB,
	except percentages)
Traffic acquisition costs:
Traffic acquisition costs related to the Yandex ad network	8,981		11,015		12,907
Traffic acquisition costs related to distribution partners	3,760		3,935		4,438
Total traffic acquisition costs	12,741		14,950		17,345
as a percentage of revenues	21.3	%	19.7	%	18.4	%
Other cost of revenues	4,069		4,804		6,592
as a percentage of revenues	6.8	%	6.3	%	7.0	%
Total cost of revenues	16,810		19,754		23,937
as a percentage of revenues	28.1	%	26.0	%	25.5	%

Cost of revenues increased by RUB 4,183 million, or 21.2%, from 2016 to 2017, primarily due to a RUB 2,395 million increase in traffic acquisition costs, and by RUB 2,944 million, or 17.5%, from 2015 to 2016, primarily due to an increase of RUB 2,209 million in traffic acquisition costs. The majority of our traffic acquisition costs relate to

56

the Yandex ad network, with a smaller portion relating to distribution relationships. Traffic acquisition costs relating to the Yandex ad network increased by RUB 1,892 million from 2016 to 2017 and by RUB 2,034 million from 2015 to 2016, representing our Yandex ad network partners’ share in the increased amount of Yandex ad network revenue for the period, which increased by RUB 2,560 million from 2016 to 2017 and by 4,580 million from 2015 to 2016. Our network partner traffic acquisition costs as a percentage of network partner revenues increased to 58.0% in 2017 compared with 55.9% in 2016 and decreased compared with 59.4% in 2015. In addition, the amounts paid to our distribution partners increased by RUB 503 million from 2016 to 2017 and by RUB 175 million from 2015 to 2016 due to growth in our existing distribution relationships, as well as the additions of new distribution partners. As a percentage of total revenues, traffic acquisition costs decreased from 21.3% in 2015 to 19.7% in 2016 and to 18.4% in 2017, as a result of changes in the partner mix.

Other cost of revenues increased by RUB 1,788 million, or 37.2%, from 2016 to 2017, primarily due to an increase of taxi related costs (RUB 769 million of corporate taxi services and RUB 220 million of other outsourced services) and RUB 738 in content acquisition and costs for outsourced services for other reportable segments. The other factor of the increase is RUB 147 million in personnel costs other than share‑based compensation expense, partially offset by a decrease of RUB 64 million of rent and utilities costs related mainly to our allocable Moscow office rent and decrease of RUB 15 million in additional share‑based compensation expense.

Other cost of revenues increased by RUB 735 million, or 18.1%, from 2015 to 2016, primarily due to an increase of RUB 507 million in content acquisition and costs for outsourced services, RUB 116 million in personnel costs other than share‑based compensation expense, RUB 87 million of rent and utilities costs related mainly to our datacenters and RUB 25 million in additional share‑based compensation expense.

The higher increase in personnel costs in 2017 compared to 2016 is primarily a result of an increase in our headcount in 2016 and 2017, that is allocated to cost of revenues, which increased from 418 as of December 31, 2015 to 467 as of December 31, 2016, but then slightly decreased to 439 closer to the end of the year 2017. The other factor of increase of personnel costs is increase of salaries in late 2016 and in the middle of 2017.

We anticipate that cost of revenues will continue to increase in absolute terms primarily as a result of increases in traffic acquisition, content and data center costs, but will remain flat as a percentage of revenues in the near term. The primary drivers of increases in our future traffic acquisition costs are the increase of revenues derived from the websites of our partners in the Yandex ad network, as well as the extent to which we use distribution partners to direct search queries to our website, partly offset by the change in the mix of Yandex ad network partners to partners with more favorable terms. In addition, our traffic acquisition costs as a percentage of advertising revenues may fluctuate in the future based on whether we are successful in negotiating more Yandex ad network and distribution arrangements that provide for lower revenue‑sharing obligations or, alternatively, in less favorable revenue‑sharing arrangements as a result of increased competition for these arrangements with existing and potential new partners.

Product development.  Product development expenses consist primarily of personnel costs incurred for the development, enhancement and maintenance of our search engine and other Yandex services and technology platforms. We also include rent and utilities attributable to office space occupied by development staff in product development expenses. We expense product development costs as they are incurred.

The following table presents our product development expenses in absolute terms and as a percentage of revenues for the periods presented:

	Year ended December 31,
	2015		2016		2017
	(in millions of RUB,
	except percentages)
Product development expenses	13,421		15,832		18,761
as a percentage of revenues	22.5	%	20.8	%	19.9	%

Product development expenses increased by RUB 2,929 million, or 18.5%, from 2016 to 2017, and by RUB 2,411 million, or 18.0%, from 2015 to 2016. These increases were primarily due to increases in salaries in 2017 and 2016, as well as increases in share-based compensation expense. Development personnel headcount increased from 3,286 as of December 31, 2015 to 3,709 as of December 31, 2016, and to 4,290 as of December 31, 2017. As a percentage of revenues, product development expenses slightly decreased by 0.9% from 2016 to 2017 and decreased by

57

1.7% from 2015 to 2016 primarily reflecting the appreciation of the Russian ruble in 2016 and 2017 which resulted in slower growth in allocable Moscow office rent and utilities which are U.S. dollar denominated.

We anticipate that product development expenses will increase in absolute terms but will not change materially as a percentage of revenues in 2018.

Sales, general and administrative.  Sales, general and administrative expenses consist of compensation and office rent expenses for personnel engaged in customer service, sales, sales support, finance, human resources, facilities, information technology and legal functions; fees for professional services; and advertising and marketing expenditures.

The following table presents our sales, general and administrative expenses in absolute terms and as a percentage of revenues for the periods presented:

	Year ended December 31,
	2015		2016		2017
	(in millions of RUB,
	except percentages)
Sales, general and administrative expenses	11,601		17,885		27,081
as a percentage of revenues	19.4	%	23.6	%	28.8	%

Sales, general and administrative expenses increased by RUB 9,196 million, or 51.4%, from 2016 to 2017 and by RUB 6,284 million, or 54.2%, from 2015 to 2016. The increase in 2017 compared to 2016 was primarily due to increases in advertising and marketing expenses, mainly in Russia, by RUB 5,923 million. Personnel expenses grew RUB 1,025 million in 2017 compared to 2016 and RUB 933 million in 2016 compared to 2015. The increase in personnel expenses in the later period resulted from an increase in sales, general and administrative headcount from 2,095 as of December 31, 2016 to 2,716 as of December 31, 2017, compared to 1,759 as of December 31, 2015.

Additional factors contributing to the overall increase from 2016 to 2017 were increases of RUB 547 million in share‑based compensation expense and RUB 273 million in recruiting and training services (which include training costs and related travel and lodging expenses, team-building and other events for staff, expenses on hires of new personnel, etc.) and business travel expenses, as well as of RUB 518 million in bank commission expenses mainly related to Yandex.Taxi and an increase by RUB 489 million in consulting and audit expenses, an increase of RUB 404 million in certain provisions related to Ukraine following the imposition of sanctions in May 2017 and RUB 233 million in other professional and outsourced services. These increases were partially compensated by a decrease of RUB 477 million of certain allowances we provided for in 2017 compared to 2016 due to VAT provision accrued in 2016 related to the results of prior years' tax audits.

Additional factors contributing to the overall increase from 2015 to 2016 were an increase of RUB 360 million of certain allowances we provided for in 2016 compared to 2015, RUB 301 million in share‑based compensation expense, RUB 137 million in business travel expenses and RUB 131 million in recruiting and training services, as well as RUB 104 million in bank commission expenses related to Yandex.Money and other payment systems, partly offset by a RUB 51 million decrease in professional and other outsourced services.

We anticipate that our sales, general and administrative expenses in 2018 will continue to increase both in absolute terms and as a percentage of revenues in comparison to 2017, as we continue to invest in the promotion of our products and services, mainly related to Yandex.Market and our experiments.

Depreciation and amortization.  Depreciation and amortization expense relates to the depreciation of our property and equipment, mainly servers and networking equipment, leasehold improvements, data center equipment and office furniture, and the amortization of our intangible assets with definite lives.

58

The following table presents our depreciation and amortization expense in absolute terms and as a percentage of revenues for the periods presented:

	Year ended December 31,
	2015		2016		2017
	(in millions of RUB,
	except percentages)
Depreciation and amortization expense	7,791		9,607		11,239
as a percentage of revenues	13.0	%	12.7	%	11.9	%

Depreciation and amortization expense increased by RUB 1,632 million, or 17.0%, from 2016 to 2017 and by RUB 1,816 million, or 23.3%, from 2015 to 2016. The increases in absolute terms for 2017 as compared to 2016 and for 2016 as compared to 2015 were primarily due to RUB 1,338 million and RUB 1,465 million increases, respectively, in depreciation expense related to server and network equipment and infrastructure systems, RUB 265 million and RUB 372 million increases, respectively, in amortization expense related to technologies and licenses not related to business acquisitions. The increases in depreciation and amortization expense in 2016 and 2017 were the result of our investments in servers and the launch of our new data center in Vladimir in 2017.

We anticipate that depreciation and amortization expense will increase in absolute terms as we continue to invest in our technology infrastructure and in business acquisitions, and slightly decrease as a percentage of revenues in the near term. Any depreciation of the Russian ruble may also result in a material increase in our capital expenditures and respective depreciation and amortization.

Share‑based compensation.  In our consolidated statements of income, share‑based compensation expense is recorded in the same functional area as the expense for the recipient’s cash compensation. As a result, share‑based compensation expense is allocated among our cost of revenues, product development expenses and sales, general and administrative expenses.

The following table presents our aggregate share‑based compensation expense in absolute terms and as a percentage of revenues for the periods presented:

	Year ended December 31,
	2015		2016		2017
	(in millions of RUB,
	except percentages)
Share‑based compensation expense	2,718		3,422		4,193
as a percentage of revenues	4.5	%	4.5	%	4.5	%

Share‑based compensation expense increased by RUB 771 million, or 22.5%, from 2016 to 2017, because of new equity‑based awards granted in 2016 and 2017.

Share‑based compensation expense increased by RUB 704 million, or 25.9%, from 2015 to 2016, because of new equity‑based awards granted in 2015 and 2016.

The share‑based compensation expense for 2016 and 2017 includes RUB 260 million and RUB 267 million, respectively, related to Business Unit Equity Awards as described in Note 15 to our consolidated financial statements.

We anticipate that share‑based compensation expense will increase in absolute terms in the near term because of new equity‑based awards.

Goodwill impairment.

The goodwill impairment recorded in 2015 of RUB 576 million relates to KinoPoisk and was a result of our annual goodwill impairment test. The impairment was a result of a combination of factors, including adverse changes in the business climate in Russia subsequent to the acquisition, and higher than expected competition in the Russian online media services sector and the resulting decrease in the projected operating results. No further goodwill impairment was recorded in 2016 and 2017.

59

Operating costs and expenses by reportable segments. Our operating costs and expenses attributable to the Search and Portal segment increased by RUB 8,188 million, or 16.6%, from 2016 to 2017 and by RUB 8,531 million, or 21.0%, from 2015 to 2016. These increases were primarily due to increases in traffic acquisition costs, personnel expenses as well as advertising expenses and depreciation and amortization expense.

Our operating costs and expenses attributable to the E‑commerce segment increased by RUB 57 million, or 1.7%, from 2016 to 2017 and by RUB 1,579 million, or 88.9%, from 2015 to 2016. These increases were primarily due to increases in personnel expenses both in 2016 and 2017, and increase of advertising and marketing expenses in 2016.

Our operating costs and expenses attributable to the Classifieds segment increased by RUB 619 million, or 44.9%, from 2016 to 2017 and by RUB 614 million, or 80.4%, from 2015 to 2016. These increases were primarily due to increases in advertising and marketing expenses as we continue to invest in the development of the service, personnel expenses resulting from increases in salary over the periods and allocable office rent and utilities.

Our operating costs and expenses attributable to the Taxi segment increased by RUB 8,462 million, or 190.7%, from 2016 to 2017 and by RUB 3,590 million, or 423.3%, from 2015 to 2016. With respect to 2017 compared to 2016, the primary factor contributing to the overall increase was an increase of RUB 5,118 million in advertising and marketing expenses. With respect to 2016 compared to 2015, the primary factor contributing to the overall increase was an increase of RUB 2,854 million in advertising and marketing expenses. These increases were also due to increases in personnel expenses resulting from increases in headcount over the periods as we continue to invest in the development of the service. We anticipate that advertising and marketing expenses of the Taxi segment will increase in absolute terms but decrease as a percentage of revenues.

Our operating costs and expenses attributable to the Experiments category increased by RUB 614 million, or 20.4%, from 2016 to 2017, but decreased by RUB 838 million, or 21.8%, from 2015 to 2016. The increase in 2017 compared to 2016 was primarily due to increase of outsource, content and software expenses, personnel expenses and advertising and marketing expenses. With respect to 2016 compared to 2015, the overall decrease was primarily due to a decrease in overall expenses in Turkey in 2016, RUB 381 million of certain allowances provided for in 2015 but not in 2016, and a decrease of RUB 325 million in advertising and marketing expenses.

Interest Income

Interest income increased from RUB 2,863 million in 2016 to RUB 2,909 million in 2017, principally as a result of an increase of average interest rates of our USD-nominated investments and due to the increase of average maturities. Interest income in 2016 decreased from RUB 3,037 million in 2015 to RUB 2,863 million in 2016 principally as a result of a decrease of average interest rates on our investments.

Interest Expense

Interest expense decreased from RUB 1,208 million in 2016 to RUB 897 million in 2017 mostly due to decrease of amortization of debt discount related to our convertible notes by RUB 227 million. Interest expense in 2016 decreased from RUB 1,293 million in 2015 to RUB 1,208 million in 2016 mostly due to decrease of amortization of debt discount related to our convertible notes by RUB 52 million.

Other Income/(Loss), Net

Our other income/(loss), net primarily consists of foreign exchange gains and losses generally resulting from changes in the value of the U.S. dollar compared with the Russian ruble, and other non‑operating gains and losses, including gains from the sale of equity securities, gains and losses from repurchases of convertible notes and gains and losses from investments in equity securities.

The following table presents the components of our other income/(loss), net in absolute terms and as a percentage of revenues, for the periods presented:

	Year ended December 31,
	2015		2016		2017

Because the functional currency of our operating subsidiaries in Russia is the Russian ruble, changes in the ruble value of these subsidiaries’ monetary assets and liabilities that are denominated in other currencies (primarily the U.S. dollar) due to exchange rate fluctuations are recognized as foreign exchange gains or losses in our consolidated statements of income. In 2015 because of the material depreciation of the ruble, we recorded in our Russian subsidiaries as other income, net foreign exchange gain of RUB 1,835 million, arising from changes in the value of the U.S. dollar compared with the Russian ruble during the year. In 2016 and 2017 we recognized foreign exchange losses in our Russian subsidiaries in the amount of 3,710 and 1,683 million due to significant appreciation of the Russian ruble against the U.S. dollar. Although the U.S. dollar values of our U.S. dollar‑denominated cash, cash equivalents and term deposits are not impacted by these currency fluctuations, they result in upward and downward revaluations of the ruble equivalent of these U.S. dollar‑denominated monetary assets.

In 2015, we repurchased $119.4 million in principal amount of our outstanding convertible notes for $102.3 million resulting in a gain of RUB 310 million. In 2016, we repurchased $87.4 million in principal amount of our outstanding convertible notes for $82.0 million resulting in a gain of RUB 53 million. In 2017, we repurchased $12.0 million in principal amount of our outstanding convertible notes for $11.6 million resulting in a loss of RUB 6 million.

Items recognized as “Other” in “Other income/(loss), net” include gains and losses from investments in equity securities, changes in the fair value of derivative instruments and other non‑operating gains and losses.

Provision for Income Taxes

The following table presents our provision for income taxes and effective tax rate for the periods presented:

	Year ended December 31,
	2015		2016		2017
	(in millions of RUB,
	except percentages)
Provision for income taxes	3,917		4,324		4,926
Effective tax rate	28.8	%	38.9	%	36.3	%

Our provision for income taxes increased by RUB 602 million from 2016 to 2017 and increased by RUB 407 million from 2015 to 2016, primarily as a result of changes in taxable income.

Our effective tax rate decreased by 2.6 percentage points from 2016 to 2017. Our effective tax rate was lower in 2017 than in 2016 primarily due to the effects of certain provisions recognized in 2016 related to the results of prior years' tax audits, partly offset by an increase in share‑based compensation expense, which is non‑deductible. Adjusted for these effects and share‑based compensation expense, our effective tax rate would have been 24.3% and 23.4% in 2017 and 2016, respectively.

Our effective tax rate increased by 10.1 percentage points from 2015 to 2016. Our effective tax rate was higher in 2016 than in 2015 primarily due to the effects of certain provisions recognized in 2016 related to the results of prior years' tax audits, as well as an increase in share‑based compensation expense, which is non‑deductible. Adjusted for

61

these effects and share‑based compensation expense, as well as for the non-deductible goodwill impairment in 2015, our effective tax rate would have been 23.4% and 22.7% in 2016 and 2015, respectively.

See “Critical Accounting Policies, Estimates and Assumptions—Tax Provisions” for additional information about our provision for income taxes.

A reconciliation of our statutory income tax rate to our effective tax rate is set forth in Note 10 of our audited consolidated financial statements included elsewhere in this Annual Report.

Quarterly Results of Operations

The following tables present our unaudited quarterly results of operations in rubles and as a percentage of revenue for the eight consecutive quarters ended December 31, 2017. You should read the following tables together with our consolidated financial statements and related notes contained elsewhere in this Annual Report. We have prepared the unaudited quarterly information on the same basis as our audited consolidated financial statements. These tables include normal recurring adjustments that we consider necessary for a fair presentation of our results of operations for the quarters presented.

Both seasonal fluctuations in internet usage and in advertising expenditures have affected, and are likely to continue to affect, our business. Internet usage and advertising expenditures generally slow down during the summer months, and increase significantly in the fourth quarter of each year. Moreover, expenditures by advertisers tend to be cyclical, reflecting overall economic conditions and budgeting and buying patterns.

Because the functional currency of our operating subsidiaries in Russia is the Russian ruble, changes in the ruble value of these subsidiaries’ monetary assets and liabilities that are denominated in other currencies (primarily the U.S. dollar) due to exchange rate fluctuations are recognized as foreign exchange gains or losses in our statements of income. As a result, our quarterly results of operations have been and will likely continue to be affected by the impact of foreign currency fluctuations on our reported results of operations, particularly changes in the value of the U.S. dollar as compared to the Russian ruble.

Our operating results for any quarter are not necessarily indicative of results for any future quarters or for a full year.

Liquidity and Capital Resources

As of December 31, 2017, we had RUB 70,707 million ($1,227.6 million) in cash, cash equivalents and term deposits. Cash equivalents consist of bank deposits with original maturities of three months or less, short-term deposits consist of bank deposits with original maturities of more than three months but no more than one year and non-current term deposits are bank deposits with original maturities of more than one year. Our current investment policy permits us to hold up to 50% of our total cash, cash equivalents, term deposits and debt securities in U.S. dollars and, additionally, to accumulate U.S. dollars for repayment of our convertible debt in 2018. In order to achieve this split of our currency holdings, we convert a portion of the rubles received from operations, as well as from maturing deposits, into U.S. dollars. We maintain our U.S. dollar‑denominated accounts principally in the Netherlands and in Russia. Our U.S. dollar‑denominated holdings as of December 31, 2017 accounted for approximately 59.6% of our cash, cash equivalents and term deposits.

 The net proceeds to us in December 2013 from the sale of our 1.125% convertible senior notes due December 15, 2018, were approximately $593.9 million; we also received net proceeds of $89.2 million related to the exercise of the underwriters’ over-allotment option in January 2014. From time to time, we repurchase and retire outstanding notes. During 2015, we repurchased and retired an aggregate of $119.4 million principal amount of the outstanding notes for $102.3 million. During 2016, we repurchased and retired an aggregate of $87.4 million principal amount of the outstanding notes for $82.0 million. During 2017, we repurchased and retired an aggregate of $12.0 million principal amount of the outstanding notes for $11.6 million.

The notes are convertible into cash, our Class A shares or a combination of cash and Class A shares, at our election, under certain circumstances, based on an initial conversion rate of 19.44 Class A shares per $1,000 principal amount of notes (which represents an initial conversion price of approximately $51.45 per share), subject to adjustment on the occurrence of certain events. A further description of the accounting treatment related to the notes can be found in Note 11 of our audited consolidated financial statements included elsewhere in this Annual Report. The net proceeds from convertible notes were received by our parent company, a Dutch holding company that generates no operating cash flow itself.

Other than the proceeds from our convertible note offering, our principal source of liquidity has been cash flow generated from the operations of our Russian subsidiaries. Under current Russian legislation, there are no restrictions on our ability to distribute dividends from our Russian operating subsidiaries to our parent other than a requirement that dividends be limited to the cumulative net profits of our Russian operating subsidiaries, calculated in accordance with Russian accounting principles, which differs from the cumulative net profit calculated in accordance with U.S. GAAP

63

primarily due to the treatment of accrued expenses (such as rent, sales agency commissions and bonuses, unused vacation), deferred taxes and differences arising from the capitalization and depreciation of property and equipment and amortization of intangible assets. In addition, these dividends cannot result in negative net assets at our Russian subsidiaries or render them insolvent. Pursuant to applicable Russian statutory rules, the amount that our principal Russian operating subsidiary would be permitted to pay as a dividend to our parent company as of December 31, 2017 was approximately RUB 85,275 million ($1,480.5 million).

We are required to pay 5% withholding tax on all dividends paid from our Russian operating subsidiaries to our parent company. Starting in 2014, we began to accrue for a 5% dividend withholding tax on the portion of the current year profit of our principal Russian operating subsidiary that is considered not to be permanently reinvested in Russia. We also provided in 2017 for a 5% dividend withholding tax on the portion of the profit for 2013 of our principal Russian operating subsidiary that was considered not to be indefinitely reinvested in Russia. As of December 31, 2017, the cumulative amount of unremitted earnings upon which dividend withholding taxes have not been provided is approximately RUB 58,795 million ($1,020.7 million). We estimate that the amount of the unrecognized deferred tax liability related to these earnings is approximately RUB 2,940 million ($51.0 million). See “Risk Factors— Taxes payable on dividends from our Russian operating subsidiaries to our parent company might not benefit from relief under the Netherlands‑Russia tax treaty.”

As of December 31, 2017, we had no outstanding indebtedness other than the convertible notes due 2018. We do not currently maintain any line of credit or other similar source of liquidity.

Cash Flows

In summary, our cash flows were:

	Year ended December 31,
	2015*	2016*	2017
	(in millions of RUB)
Net cash provided by operating activities	19,375	25,286	23,772
Net cash used in investing activities	(11,734)	(13,106)	(7,788)
Net cash used in financing activities	(6,211)	(5,549)	(587)
Effect of exchange rate changes on cash	5,052	(3,449)	(976)

_________________________________________________________________________________

* In Q1 2017, Yandex elected to early adopt Accounting Standards Update ("ASU") No. 2016-18—Statement of Cash Flows (Topic 230): Restricted Cash, which provided revised guidance on the classification and presentation of restricted cash in the statement of cash flows on a retrospective basis. Prior periods have been adjusted accordingly.

Cash provided by operating activities.  Cash provided by operating activities consists of net income adjusted for non‑cash items, including depreciation and amortization expense, amortization of debt discount and issuance costs, share‑based compensation expense, deferred tax benefit/expense, foreign exchange gains and losses, gains/(losses) from repurchases of convertible notes, gain from sale of equity securities, goodwill impairment and the effect of changes in working capital.

Cash provided by operating activities decreased by RUB 1,514 million from 2016 to 2017. This decrease was primarily due to a decrease of RUB 2,821 million in cash provided by changes in working capital partially offset by an increase in net cash from operations before changes in working capital of RUB 1,307 million. Cash used in working capital was RUB 978 million in 2017 and decreased between the periods primarily due to a significant increase in prepaid expenses and other assets in 2017 compared to 2016, principally arising from increases in funds receivable from payment processing systems and interest receivable accrued, as well as a decrease in accounts payable and accrued liabilities that were primarily related to tax provisions we accrued in 2016 as a result of prior years' tax audits.

Cash provided by operating activities increased by RUB 5,911 million from 2015 to 2016. This increase was primarily due to an increase in net cash from operations before changes in working capital of RUB 4,196 million and an increase of RUB 1,715 million in cash provided by changes in working capital. Cash provided by working capital was RUB 1,843 million in 2016 and increased between the periods primarily due to significant increases in accounts payable and accrued liabilities that were primarily related to tax provisions we accrued in 2016 as a result of prior years' tax audits.

64

We believe that our existing cash, cash equivalents and cash generated from operations will be sufficient to satisfy our currently anticipated cash requirements through at least the next 12 months. To the extent that our cash, cash equivalents and cash from operating activities are insufficient to fund our future activities, we may be required to raise additional funds through equity or debt financings, including bank credit arrangements. Additional financing may not be available on terms favorable to us or at all.

Cash used in investing activities.

Cash used in investing activities in 2017 decreased by RUB 5,318 million compared to 2016 as a result of decreases in investments in term deposits (net of repayments) of RUB 4,632 million and in investments in debt securities (net of proceeds from maturities) of RUB 3,521 million, as well as decreases in loans granted of RUB 384 million and investments in non-marketable equity securities of RUB 300 million, which were partly compensated by increases in capital expenditures of RUB 2,764 million and in cash paid for acquisitions of new businesses of RUB 918 million.

Cash used in investing activities in 2016 increased by RUB 1,372 million compared to 2015 as a result of increases in investments in term deposits (net of repayments) of RUB 2,905 million and in investments in debt securities (net of proceeds from maturities) of RUB 1,496 million, as well as increases in loans granted of RUB 490 million and investments in non-marketable equity securities of RUB 381 million, which were partly compensated by decreases in capital expenditures of RUB 3,420 million and in cash paid for acquisitions of new businesses of RUB 398 million.

Our total capital expenditures were RUB 12,389 million in 2017 and RUB 9,625 million in 2016. Our capital expenditures have historically consisted primarily of the purchases of servers and networking equipment. We also incurred significant capital expenditures in 2016 and 2017 related to the construction of one of our larger data centers. To manage enhancements in our search technology, expected increases in internet traffic, advertising transactions and new services, and to support our overall business expansion, we will continue to invest in data center operations, technology, corporate facilities and information technology infrastructure in 2018 and thereafter. Moreover, we may spend a significant amount of cash on acquisitions and licensing transactions from time to time.

Cash used in financing activities.

For 2017, cash outflow from financing activities was RUB 587 million, reflecting RUB 668 million used to repurchase our outstanding convertible notes and RUB 195 million paid as contingent consideration, partly offset by proceeds of RUB 328 million from share option exercises.

For 2016, cash outflow from financing activities was RUB 5,549 million, reflecting RUB 5,397 million used to repurchase our outstanding convertible notes and RUB 680 million paid as contingent consideration, partly offset by proceeds of RUB 431 million from share option exercises.

Off‑Balance Sheet Items

We do not currently engage in off‑balance sheet financing arrangements, and do not have any material interest or obligation, including a contingent obligation, arising out of a variable interest, in entities referred to as variable interest entities, which include special purpose entities and other structured finance entities.

The table above presents our long‑term rent obligations for our office and data center facilities, contractual purchase obligations related to data center operations and facility build‑outs, as well as other purchase obligations primarily related to fixed utilities fees, technology licenses and other services and obligations related to repayment of our convertible notes due 2018. For agreements denominated in U.S. dollars, the amounts shown in the table above are based on the U.S. dollar/Russian ruble exchange rate prevailing on December 31, 2017. All amounts shown include value added tax, where applicable.

Critical Accounting Policies, Estimates and Assumptions

Our accounting policies affecting our financial condition and results of operations are more fully described in our consolidated financial statements for the years ended December 31, 2015, 2016 and 2017, included elsewhere in this Annual Report. The preparation of these consolidated financial statements requires us to make judgments in selecting appropriate assumptions for calculating financial estimates, which inherently contain some degree of uncertainty. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities and the reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe our critical accounting policies that affect the more significant judgments and estimates used in the preparation of our consolidated financial statements are as follows:

Tax Provisions

Significant judgment is required in evaluating our uncertain tax positions and determining our provision for income taxes. FASB authoritative guidance on accounting for uncertainty in income taxes requires a two‑step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement.

Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate, as well as the related net interest. Our actual Russian taxes may be in excess of the estimated amount expensed to date and accrued as of December 31, 2017, due to ambiguities in, and the evolution of, Russian tax legislation, varying approaches by regional and local tax inspectors, and inconsistent rulings on technical matters at the judicial level. See “Risk Factors—Risks Related to Doing Business and Investing in Russia and Other Countries in which We Operate—Changes in the tax systems of Russia and other countries in which we operate, as well as unpredictable or unforeseen application of existing rules, may materially adversely affect our business, financial condition and results of operations.”

66

In addition, significant management judgment is required in determining whether deferred tax assets will be realized. A valuation allowance is recognized to reduce deferred tax assets to amounts that are more likely than not to ultimately be utilized based on our ability to generate sufficient future taxable income. Establishing or reducing a tax valuation allowance requires us to make assessments about the timing of future events, including the probability of expected future taxable income and available tax planning strategies. If actual events differ from management’s estimates, or to the extent that these estimates are adjusted in the future, any changes in the valuation allowance could materially impact our consolidated financial statements.

Recognition and Impairment of Goodwill and Intangible Assets

The FASB authoritative guidance requires us to recognize the assets of businesses acquired and respective liabilities assumed based on their fair values. Our estimates of the fair value of the identified intangible assets of businesses acquired are based on our expectations of the future results of operations of such businesses. The fair value assigned to identifiable intangible assets acquired is supported by valuations that involve the use of a large number of estimates and assumptions provided by management.

We assess the carrying value of goodwill arising from business combinations on an annual basis, or more frequently if events or changes in circumstances indicate that such carrying value may not be recoverable. Other than our annual review, factors we consider important that could trigger an impairment review include under‑performance of our reporting units compared with our internal budgets or changes in projected results, changes in the manner of utilization of the asset, and negative market conditions or economic trends. We determine whether impairment has occurred by assigning goodwill to the reporting unit identified in accordance with the authoritative guidance, and comparing the carrying amount of the reporting unit to the fair value of the reporting unit. We generally measure the fair value of the reporting unit by considering discounted estimated future cash flows using an appropriate discount rate. Therefore, our judgment as to the future prospects of our business has a significant impact on our results and financial condition. If these future prospects do not materialize as expected or there is a future adverse change in market conditions, we may be unable to recover the carrying amount of an asset, resulting in future impairment losses.

Share‑Based Compensation Expense

We estimate the fair value of share options and share appreciation rights (together, “Share‑Based Awards”) that are expected to vest using the Black‑Scholes‑Merton (BSM) pricing model and recognize the fair value ratably over the requisite service period using the straight‑line method. We used the following assumptions in our option‑pricing model when valuing Share‑Based Awards for grants made in the year ended December 31, 2017:

	Year ended December 31, 2017
Expected life of the awards (years)	7.19
Expected annual volatility	40	%
Risk‑free interest rate	2.23	%
Expected dividend yield	—

No share options grants were made for the years ended December 31, 2015 and 2016. No SARs grants were made for the years ended December 31, 2015, 2016 and 2017.

To determine the expected option term, we use the “simplified method” as allowed under the SEC’s accounting guidance, which represents the weighted‑average period during which our awards are expected to be outstanding.

With respect to price volatility, for 2017 grants we used historical volatility of our own shares.

We base the risk‑free interest rate on the U.S. Treasury yield curve in effect at the grant date.

We did not declare any external dividends with respect to 2015, 2016 or 2017 and do not have any plans to pay dividends in the near term. We therefore use an expected dividend yield of zero in our option pricing model for awards granted in the year ended December 31, 2017.

67

Until the fourth quarter of 2016, we determined the amount of share‑based compensation expense based on awards that we ultimately expect to vest, taking into account estimated forfeitures. U.S. GAAP required forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We calculated the forfeiture rate by reference to our historical employee turnover rate. If our actual forfeiture rate is materially different from the estimate, share‑based compensation expense could be materially lower than what has been recorded. Starting the fourth quarter of 2016, we early adopted an Accounting Standard Update (“ASU”), which simplifies certain aspects of the accounting for share-based payment transactions to employees. We also elected to account for forfeitures as they occur, rather than estimate expected forfeitures.

Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Exchange Risk

The functional currency of our Russian operating subsidiaries, which account for the significant majority of our operations, is the Russian ruble. Therefore, our reported results of operations are impacted by fluctuations in exchange rates to the extent that we recognize foreign exchange gains and losses on monetary assets and liabilities denominated in currencies other than the ruble, primarily the U.S. dollar. Total U.S. dollar denominated cash, cash equivalents, term deposits and short‑term debt securities held in Russia amounted to RUB 32,953 million and RUB 34,827 million as of December 31, 2017 and 2016, respectively. If the U.S. dollar had been stronger/weaker by 15% relative to the value of the Russian ruble as of December 31, we would have recognized additional foreign exchange gains/losses before tax of RUB 4,888 million and RUB 4,424 million in 2017 and 2016, respectively.

Furthermore, the revenues and expenses of our Russian operating subsidiaries are primarily denominated in Russian rubles. However, as was customary in the Russian real estate market, the majority of our rent expenses, currently including the leases for our Moscow headquarters, is denominated in U.S. dollars. Additionally, a major portion of our capital expenditures, primarily servers, networking and engineering equipment imported by Russian suppliers, can also be materially affected by changes in the dollar‑ruble and euro‑ruble exchange rate. In the event of a material appreciation of the U.S. dollar against the ruble, such as that which occurred in 2015, the ruble equivalents of these U.S. dollar‑denominated expenditures increase and negatively impact our net income and cash flows.

The leases of our Moscow headquarters currently entail outstanding commitments of approximately RUB 15,277 million as of December 31, 2017. The rent under the leases we entered into before 2017 is denominated in U.S. dollars, but payable in rubles at the then‑current exchange rate quoted by the Central Bank of Russia. The leases protect the landlord against depreciation of the U.S. dollar against the ruble. The landlord’s protection from U.S. dollar depreciation represents an embedded derivative that must be bifurcated and accounted for separately under U.S. GAAP. At the end of each period, we re‑measure the fair value of this embedded derivative and record any change in fair value as foreign exchange gains or losses in the statements of income. We estimate the fair value of this derivative instrument using a model that is sensitive to changes in the U.S. dollar to Russian ruble exchange rate. If the U.S. dollar had been weaker by 15% relative to the value of the Russian ruble as of December 31, 2017, we would have recognized additional foreign exchange gains before tax of RUB 3 million in 2017. If the U.S. dollar had been stronger by 15% relative to the value of the Russian ruble as of December 31, 2017, we would have recognized additional foreign exchange losses before tax of RUB 3 million in 2017. In March 2017, we designated a portion of our U.S. dollar-denominated term deposits with a third party bank as a hedging instrument to protect us from risk that our U.S. dollar-denominated Moscow headquarters rent expenses will be adversely affected by changes in the exchange rates and to avoid income statement volatility. See Note 6 — “Derivative and non-derivative financial instruments” in the Notes to our consolidated financial statements included elsewhere in this Annual Report.

The functional currency of our Dutch parent company is the U.S. dollar. The functional currency of our subsidiaries incorporated in other countries is generally the respective local currency. The financial statements of these non‑Russian entities have been translated into rubles using the current rate method, where balance sheet items are translated into rubles at the period‑end exchange rate and revenue and expenses are translated using a weighted average exchange rate for the relevant period. The resulting translation gains and losses for the years ended December 31, 2015,

68

2016 and 2017 are included as a foreign currency translation adjustment recorded as part of accumulated other comprehensive income on our consolidated balance sheets. U.S. dollar cash, cash equivalents and term deposits comprise the largest portion of our assets in the Netherlands. Total U.S. dollar denominated cash, cash equivalents and term deposits held in the Netherlands amounted to RUB 8,291 million and RUB 5,955 million as of December 31, 2017 and 2016, respectively. If the U.S. dollar had been stronger/weaker by 15% relative to the value of the Russian ruble as of December 31, we would have recognized additional other comprehensive gains/losses of RUB 1,338 million and RUB 828 million in 2017 and 2016, respectively.

Subsequent to December 31, 2017, the Russian ruble remained volatile against foreign currencies, including the U.S. dollar. The currency exchange rate as of December 31, 2017 was RUB 57.6002 to $1.00 and, during the period from December 31, 2017 to March 21, 2018, the exchange rate of the Russian ruble depreciated to RUB 57.7033 to $1.00. The lowest rate reached during this period was RUB 58.1718 to $1.00 as of February 10, 2018. The highest rate reached during this period was RUB 55.6717 to $1.00 as of February 28, 2018.

Interest Rate Risk

We had cash, cash equivalents and term deposits of RUB 70,707 million as of December 31, 2017. We do not believe that we have any material exposure to changes in the fair value of our cash, cash equivalents and term deposits as a result of changes in interest rates. We do not enter into investments for trading or speculative purposes. Declines in interest rates, however, will reduce future investment income.

In December 2013, we issued and sold $600.0 million in aggregate principal amount of 1.125% convertible senior notes due December 15, 2018. In January 2014, we issued and sold an additional $90.0 million in aggregate principal amount of such notes. During 2015, we repurchased and retired an aggregate of $119.4 million principal amount of the outstanding notes for $102.3 million. During 2016, we repurchased and retired an aggregate of $87.4 million principal amount of the outstanding notes for $82.0 million. During 2017, we repurchased and retired an aggregate of $12.0 million principal amount of the outstanding notes for $11.6 million. We carry the convertible notes at face value less unamortized discount and debt issuance costs on our balance sheet. The fair value of the notes changes when the market price of our shares or interest rates fluctuate.

Compensation and Share Ownership of Executive Officers and Directors.

The aggregate cash compensation paid or accrued in 2017 for members of our management team (a total of 14 persons), as a group, was RUB 378 million ($6.6 million).

In May 2011, we granted each of our non‑executive directors an option to acquire 28,000 Class A shares at the initial public offering price of $25.00 per share, effective on the closing of our initial public offering. Such options vested over a four‑year period. In May 2013, we granted to a new non‑executive director an option to acquire 28,000 Class A shares at a price of $27.74 per share. In May 2014, we granted a new non‑executive director an option to acquire 28,000 Class A shares at a price of $33.09 per share.

In May 2015, our Compensation Committee and Board approved grants of further equity awards to the members of our Board. Each member was granted 14,000 restricted shares units (below – “RSUs”).

Corporate Governance

We have an audit committee, a compensation committee and a nominating and corporate governance committee. We have adopted a charter for each of these committees.

Audit Committee

Our audit committee consists of Messrs. Ryan (chairperson), Boynton and Ms. Dyson. Each member satisfies the “independence” requirements of the NASDAQ listing standards, and Mr. Ryan qualifies as an “audit committee financial expert,” as defined in Item 16A of Form 20‑F and as determined by our board of directors. The audit committee oversees our accounting and financial reporting processes and the audits of our consolidated financial statements. The audit committee is responsible for, among other things:

· making recommendations to our board of directors regarding the appointment by the shareholders of our independent auditors;

· overseeing the work of the independent auditors, including resolving disagreements between management and the independent auditors relating to financial reporting;

· pre‑approving all audit and non‑audit services permitted to be performed by the independent auditors;

· reviewing the independence and quality control procedures of the independent auditors;

· discussing material off‑balance sheet transactions, arrangements and obligations with management and the independent auditors;

· reviewing and approving all proposed related‑party transactions;

· discussing the annual audited consolidated and statutory financial statements with management;

· annually reviewing and reassessing the adequacy of our audit committee charter;

· meeting separately with the independent auditors to discuss critical accounting policies, observations on internal controls, the auditor’s engagement letter and independence letter and other material written communications between the independent auditors and the management; and

· attending to such other matters as are specifically delegated to our audit committee by our board of directors from time to time.

Compensation Committee

Our compensation committee consists of Messrs. Rijnja (chairperson), Boynton and Ms. Dyson. Each member satisfies the “independence” requirements of the NASDAQ listing standards. The compensation committee assists the board of directors in reviewing and approving or recommending our compensation structure, including all forms of compensation relating to our directors and management. Members of our management may not be present at any committee meeting while the compensation of our chief executive officer is deliberated. Subject to the terms of the remuneration policy approved by our general meeting of shareholders from time to time, as required by Dutch law, the compensation committee is responsible for, among other things:

· reviewing and making recommendations to the board of directors with respect to compensation of our executive and non‑executive directors;

· reviewing and approving the compensation, including equity compensation, change‑of‑control benefits and severance arrangements, of our chief financial officer and such other members of our management as it deems appropriate;

72

· overseeing the evaluation of our management;

· reviewing periodically and making recommendations to our board of directors with respect to any incentive compensation and equity plans, programs or similar arrangements;

· exercising the rights of our board of directors under any equity plans, except for the right to amend any such plans unless otherwise expressly authorized to do so; and

· attending to such other matters as are specifically delegated to our compensation committee by our board of directors from time to time.

Nominating and Corporate Governance Committee

Our nominating and corporate governance committee consists of Messrs. Boynton (chairperson), Rijnja and Volozh. Each member satisfies the “independence” requirements of the NASDAQ listing standards. The nominating and corporate governance committee assists the board of directors in selecting individuals qualified to become our directors and in determining the composition of the board of directors and its committees. The nominating and corporate governance committee is responsible for, among other things:

· recommending to the board of directors persons to be nominated for election or re‑election as directors at any meeting of the shareholders;

· overseeing the board of directors’ annual review of its own performance and the performance of its committees; and

· considering, preparing and recommending to the board of directors a set of corporate governance guidelines applicable to the company.

Employment Agreements

Substantially all of our employees are employed by our operating subsidiaries. Our employment agreements generally contain the minimum statutory notice periods required under Russian law. The employment agreements between our subsidiaries and certain senior managers and other employees contain non‑competition and non‑solicitation provisions, although we understand that such provisions are generally unenforceable under Russian law.

Employees

The following table indicates the composition of our workforce as of December 31 each year indicated:

	2015	2016	2017
Russia	4,970	5,877	7,166
Other	493	394	279
Total	5,463	6,271	7,445

	2015	2016	2017
Product development	3,286	3,709	4,290
Sales, general and administration	1,759	2,095	2,716
Cost of sales	418	467	439
Total	5,463	6,271	7,445

We also typically employ several hundred contract workers on a part‑time basis which are not reflected in the table above, and the numbers of such contract workers generally vary in line with the numbers of full‑time staff.

Our employees are not represented by any collective bargaining agreements and we have never experienced a work stoppage. We believe our employee relations are good.

73

Employee Plans

We grant equity awards in the form of share options, share appreciation rights, restricted shares and restricted share units (or so called “deferred shares”) under our Fourth Amended and Restated 2007 Equity Incentive Plan (the “2007 Plan”) and our 2016 Equity Incentive Plan (the “2016 Plan” and together with the 2007 Plan, the “Plans”) (“Company Awards”).  Our 2016 Plan was approved at our 2016 annual general meeting of shareholders on May 27, 2016 and replaced our 2007 Plan.  However, there remain unexercised grants under our 2007 Plan. The total number of shares available for issuance under the Plans is equal to 15% of the aggregate number of Class A and Class B shares outstanding from time to time.

Additionally, the 2016 Plan provides employees at certain of our business units, including Taxi, Classifieds and Market (the “Participating Subsidiaries”), the opportunity to receive equity awards in respect of such Participating Subsidiary (the “Business Unit Equity Awards”). Business Unit Equity Awards and any awards granted to management of the Participating Subsidiaries outside of the 2016 Plan are to not exceed 20% of such Participating Subsidiary’s shares issued and outstanding from time to time. In the future, additional of our business units may become Participating Subsidiaries.

Plan administration.  Our board of directors or its compensation committee administers our Plans. Although our Plans sets forth certain terms and conditions of our equity awards, our board of directors or its compensation committee determines the provisions and terms and conditions of each grant. These include, among other things, the vesting schedule, repurchase provisions, forfeiture provisions, and form of payment upon exercise.

Eligibility.  We may grant Company Awards to employees and directors of and consultants to our company and its subsidiaries. With respect to Business Unit Equity Awards, we may grant awards in the equity of a Participating Subsidiary to employees, officers, members of the board of directors, advisors and consultants of such Participating Subsidiary.

Exercise price and term of equity awards.  With respect to the Company Awards, the exercise price of options or measurement price of share appreciation rights awards is the average closing price per Class A share on the NASDAQ Global Select Market on the 20 trading days immediately following the grant date. With respect to Business Unit Equity Awards, the exercise price of options or measurement price of share appreciation rights shall be determined from time to time by the Board (following consultation with an independent valuation expert). Restricted share unit awards have no exercise or measurement price. Equity awards are generally exercisable up until the tenth anniversary of the grant date so long as the grantee’s relationship with us has not terminated.

Vesting schedule.  The notice of grant specifies the vesting schedule. Awards generally vest over a four‑year period, with 4/₁₆ths vesting on the first anniversary of grant and an additional 1/₁₆th vesting each quarter thereafter. When a grantee’s employment or service is terminated, the grantee may generally exercise his or her options that have vested as of the termination date within ninety days of termination or as determined by our plan administrator.

Class A and Class B Shares.  Outstanding options granted prior to October 2008 may be exercised, pursuant to their terms and the terms of the 2007 Plan, as follows:

· In the event that an optionee intends to exercise an option and immediately sell the shares acquired, we will issue Class A shares upon such exercise.

· In the event that an optionee intends to exercise an option and hold the shares acquired for some period of time, we will issue Class B shares upon such exercise. Such Class B shares will be subject to the transfer and conversion provisions applicable to all Class B shares.

Equity awards granted since October 2008 are in respect of Class A shares only, in accordance with their terms and the terms of the Plans.

Amendment and Termination.  Our board of directors may at any time amend, suspend or terminate our 2016 Plan. Prior to any such amendment, suspension or termination, our board of directors must first make a determination that share options already granted will not be adversely affected. Unless terminated earlier, our 2016 Plan will continue in effect until May 2026.

74

Equity Award Exchanges.  In April 2015, we offered certain of our employees the opportunity to exchange outstanding share appreciation rights awards for new restricted share unit awards. As a result of recent economic and market conditions, the value of our Class A shares has fluctuated significantly in recent periods and we believed that restricted share unit awards would provide a better incentive for our employees in these conditions. Each eligible employee was therefore given the opportunity to exchange outstanding share appreciation rights awards for restricted share unit awards on a two‑for‑one basis (two share appreciation rights for one restricted share unit), subject to longer vesting and exercisability terms. In particular, such replacement awards vest over a five‑year period, compared with the four‑year vesting term of the original share appreciation rights awards. A total of 14 employees, including our Chief Operating Officer and Chief Financial Officer, participated in the offer, exchanging a total of 1,663,750 share appreciation rights for a total of 831,875 restricted share units.

In July and September 2015, we completed additional exchanges of outstanding share appreciation rights awards for new restricted share unit awards based on an exchange ratio of 2:1. In all but one instance, the exchanges were effected for non‑senior employees and the replacement restricted share units are subject to the same vesting schedule as was in place for the replaced share appreciation rights awards. An exchange was also offered to and accepted by one senior employee; in this case the replacement restricted share units were granted on the condition that vesting be reset to begin as of January 1, 2016.

As a result of the exchanges, a total of 42 employees exchanged an aggregate of 256,850 share appreciation rights for an aggregate of 128,426 restricted share units during the third quarter of 2015.

In May 2016, we made an offer to our non‑executive directors to exchange up to an aggregate of 196,000 of their outstanding options for RSUs based on an exchange ratio of 2:1. As a result of exchange, a total of seven nonexecutive directors exchanged an aggregate of 196,000 options for an aggregate of 98,000 RSUs. The replacement RSUs are subject to an additional 12 months vesting period beyond the original vesting schedule of the exchanged options. In addition, no exercise of the replacement RSUs is permitted for a 12 month period starting the date of exchange.

Item 7.  Major Shareholders and Related Party Transactions.

The following table contains information concerning each of our directors and members of our senior management and each shareholder known by us to beneficially own more than five percent of each class of our outstanding ordinary shares. Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission and includes voting or investment power with respect to our shares.

The number of shares outstanding used in calculating the percentage for each listed shareholder includes the shares underlying options held by such shareholder that are exercisable within 60 days of February 15, 2018. The percentage of beneficial ownership is based on 287,942,319 Class A shares and 39,254,658 Class B shares outstanding as of February 15, 2018. All holders of our ordinary shares, including those shareholders listed below, have the same

Related Party Transactions

Shareholders’ Agreement

Shareholders holding an aggregate of approximately 49 million Class A and Class B shares, representing approximately 56% of the voting power of our outstanding shares, are parties to a shareholders agreement, the principal terms of which are as follows:

Board composition.  The parties have agreed to vote all of our shares held by them in favor of electing or re‑electing those persons nominated by our board of directors for election or re‑election as a director at any general meeting of our shareholders.

Compliance with foreign ownership laws.  The parties have agreed to comply with any applicable laws from time to time in effect that regulate the owners of Yandex by non‑Russian parties.

Amendments to articles of association.  The parties have agreed that they will vote against any proposal to amend the articles of association in such a way as to eliminate:

· our multiple class share structure, with differential voting rights;

· the staggered three‑year terms of our directors;

· the provision that our directors may only be removed by a two‑thirds majority of votes cast representing at least 50% of our outstanding share capital;

· the authorized preference shares;

· requirements that certain matters, including an amendment of our articles of association, may only be brought to our shareholders for a vote upon a proposal by our board of directors;

· the supermajority requirements for shareholder approval of certain significant corporate actions, including a legal merger or demerger of our company or the amendment of our articles of association;

77

· the right of our board of directors to approve the accumulation by a party, group of related parties or parties acting in concert of the legal or beneficial ownership of 25% or more, in number or by voting power, of our outstanding Class A and Class B shares (taken together); or

· the rights of the holder of the priority share.

Term and Amendment.  The shareholders agreement will remain in effect so long as any Class B shares remain outstanding. The agreement may be terminated and amended, and any provision thereof waived, with the prior written consent of parties to the agreement holding shares representing more than 662/₃% of the voting power of the outstanding share capital held by parties to the agreement. The agreement will terminate with respect to any particular shareholder upon its affirmative election if it no longer holds any Class B Shares, as a result of the transfer of all Class B shares held by it, or the voluntary or mandatory conversion of all Class B Shares held by it into Class A Shares.

Registration Rights Agreement

We are party to a registration rights agreement with our major shareholders that allows them to require us to register Class A shares held by them under the U.S. Securities Act of 1933, as amended (the “Securities Act”), under certain circumstances.

Demand registration rights.  Shareholders party to the agreement together holding approximately 34 million Class A and Class B shares have the right to require that we register their securities for sale. Certain other shareholders have the right to join in a demand registration. We have the right not to effect a demand registration (a) if we have already effected one demand registration, (b) if the aggregate price, net of underwriters’ discounts or commissions, of all registrable securities included in such registration is less than $7,500,000, (c) if the initiating shareholders propose to register securities that may be immediately registered on Form F‑3, or (d) in a jurisdiction where we would be required to qualify to do business or execute a general consent to service of process in effecting such a registration. We have the right to defer filing of a registration statement for up to 120 days if our board of directors determines in good faith that filing of a registration statement would be detrimental to us, but we cannot exercise such deferral right more than once in any 12‑month period.

Piggyback registration rights.  If we propose to file a registration statement for a public offering of our securities other than relating to an employee share option, share purchase or similar plan or pursuant to a merger, exchange offer, or similar transaction, then we must offer holders of registrable securities an opportunity to include in this registration all or any part of their registrable securities. We must use our best effort to cause the underwriters in any underwritten offering to permit the shareholders who so requested to include their shares on the same terms and conditions as our securities to be registered.

Form F‑3 registration rights.  When we are eligible to use Form F‑3, one or more shareholders party to the agreement holding shares with an aggregate market value of at least $50,000,000 have the right to request that we file a registration statement on Form F‑3. We are not obligated to file a registration statement on Form F‑3 if (a) we have already effected two registrations on Form F‑3 for holders of registrable securities during the 12‑month period preceding a registration request, (b) the aggregate price, net of underwriters’ commissions or discounts, of registrable securities included in such registration is less than $10 million, or (c) in a jurisdiction where we would be required to qualify to do business or execute a general consent to service of process in effecting such a registration. We have the right to defer filing of a registration statement for up to 120 days if our board of directors determines in good faith that filing of a registration statement would be detrimental to us, but we cannot exercise such deferral right more than once in any 12‑month period.

Expenses of registration.  We will pay all expenses relating to any demand, piggyback or F‑3 registration, other than underwriting commissions and discounts.

Relationship with Sberbank

Sberbank is a major financial institution and the largest savings bank in the Russian Federation. Approximately 51% of its voting shares are held by the Central Bank of the Russian Federation. Herman Gref, the Chief Executive Officer and Chairman of the Executive Board of Sberbank, is a member of our Board of Directors.

78

Priority Share

In September 2009, we issued our priority share to Sberbank for its nominal value of €1.00. As the holder of our priority share, Sberbank has the right to approve the accumulation by a party, group of related parties or parties acting in concert, of the legal or beneficial ownership of shares representing 25% or more, in number or by voting power, of our outstanding Class A and Class B shares (taken together), if our board of directors has otherwise approved such accumulation of shares. In addition, any decision by our board of directors to sell, transfer or otherwise dispose of, directly and indirectly, all or substantially all of our assets to one or more third parties in any transaction or series of related transactions, including the sale of our principal Russian operating subsidiary, is subject to the prior approval of the holder of our priority share. The priority share does not carry any rights to control the management or operations of our company, and its economic rights are limited to its pro rata entitlement to dividends and other distributions. Our articles of association provide that the priority share may only be held by a party that is specifically nominated by our board of directors for this purpose. The rights of the priority share would terminate if any law is adopted or amended in Russia that restricts the ownership by non‑Russian parties of internet businesses in Russia.

Our board of directors and shareholders approved the priority share mechanism with the objective of strengthening control over our company’s ownership structure and providing transparency into changes in share ownership. We believe that this structure allows us to avoid the dominance of any single group of investors. In addition, we believe that this mechanism allows us to attract appropriate levels of both Russian and non‑Russian investment.

In nominating Sberbank as the party to which the priority share would be issued, our board of directors considered three principal criteria: the holder had to be controlled by the Russian government, the holder had to be public, and the holder could not have interests in the internet or media sectors that would conflict with the interests of our business. Our board also considered Sberbank to be an appropriate holder of the priority share in light of what our board believes to be its respected and professional management team. Because our board views the holder of the priority share as playing a valuable role in contributing to the stability of our business and the transparency of our shareholder base, and because the priority share carries only an immaterial economic interest in our company, we issued the priority share for only nominal consideration.

Yandex.Money Joint Venture

In July 2013, we sold a 75 percent (less 1 ruble) interest in our Yandex.Money business to Sberbank for $60 million in cash and entered into a joint venture arrangement with Sberbank in respect of the future operation of this business, which continues under the Yandex.Money brand. Our joint venture agreement with Sberbank provides for standard minority protections and addresses corporate governance matters such as veto rights, deadlock mechanisms and rights of first refusal and co‑sale.

Following the sale of the controlling interest and deconsolidation of Yandex.Money in July 2013, we retained a noncontrolling interest and significant influence over Yandex.Money’s business. We continue to use Yandex.Money for payment processing and sublease to Yandex.Money part of our premises. The amount of revenues from subleasing and other services was RUB 106 million and RUB 86 million ($1.5 million) for the years ended December 31, 2016 and 2017, respectively. The amount of fees for online payment commissions was RUB 173 million and RUB 439 million ($7.6 million) for the years ended December 31, 2016 and 2017 respectively. As of December 31, 2016 and 2017, the amount of receivables related to payment processing was RUB 47 million and RUB 158 million ($2.7 million), respectively. We believe that the terms of the agreements with Yandex.Money are comparable to the terms obtained in arm’s‑length transactions with unrelated similarly situated customers and suppliers.

Advisory Fees; Lending Arrangements

In December 2015, we engaged Sberbank CIB, an affiliate of Sberbank, as our financial advisor in connection with our proposed acquisition of a legal entity that will hold title to the office complex in central Moscow in which our Russian headquarters are located. Pursuant to this engagement, we have paid Sberbank CIB advisory fees of $0.2 million. On February 19, 2016, we entered into a framework agreement with Krasnaya Roza 1875 Limited, a Cypriot company, or KR 1875, for the acquisition of certain buildings in the Krasnaya Roza office complex in central Moscow, in which the Russian headquarters of the Yandex group are located (the “Framework Agreement”). On September 7, 2016, we opted to terminate the Framework Agreement because of changing market conditions. Yandex plans to remain at the Red Rose through the end of the lease term in 2021 but may consider other options for when the lease term expires

79

Internet-acquiring agreement with Sberbank

In October 2017 the Company entered into new internet-acquiring agreement with Sberbank. The amount of fees was RUB 45 ($0.8) for the year ended December 31, 2017.

Loans granted to related parties

In 2017, we had loans outstanding in the aggregate principal amount of RUB 173 million ($3.0 million) to the CEOs of our business units, principally in connection with their purchase of equity interests in those subsidiaries, and to certain senior employees. The interest rate on the loans is up to 8% per annum and they mature in 2019-2022.

Item 8.  Financial Information.

See the financial statements beginning on page F‑1.

Dividends

We do not have any present plan to pay cash dividends on our shares in the near term. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors may deem relevant.

If and when we pay dividends in the future, they will be payable on a pari passu basis on the outstanding Class A and Class B shares and the priority share. Although our Class C shares are technically entitled to a maximum dividend of €0.01 per share when we declare dividends on our Class A and Class B shares, we intend to repurchase all Class C shares issued upon conversion of our Class B shares promptly following their issuance such that no dividends would be payable on our Class C shares. Cash dividends on our shares, if any, will be paid in U.S. dollars.

Item 10.  Additional Information.

Memorandum and Articles of Association

We incorporate by reference into this Annual Report the description of our amended articles of association contained in our F‑1 registration statement (File No. 333‑173766) originally filed with the SEC on April 28, 2011, as amended. Our articles of association were amended as of May 21, 2012, May 22, 2013, May 23, 2014, May 22, 2015 and 1 June, 2016. Such amendments reduced the number of authorized shares upon the conversion of our Class B shares into Class A shares or were technical in nature to conform with changes in the requirements of Dutch law.

Material Contracts

Convertible debt

We issued and sold $690 million in aggregate principal amount of 1.125% convertible senior notes due 2018, to qualified institutional buyers in reliance on Rule 144A under the United States Securities Act of 1933, as amended, in transactions closing December 17, 2013, and January 14, 2014.

In connection with the offering of the notes, we entered into an Indenture, dated December 17, 2013, with the Bank of New York Mellon, a New York banking corporation, as trustee, which includes the terms and conditions upon which the notes are to be authenticated, issued and delivered. The notes are convertible into cash, Class A shares of Yandex or a combination of cash and Class A shares, at our election, based on an initial conversion rate of 19.4354 Class A shares per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $51.45 per Class A share, subject to adjustment on the occurrence of certain events. Prior to June 15, 2018, the notes are convertible only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the close of business on the business day immediately preceding the maturity date of the notes.

82

The notes bear interest at a rate of 1.125% per year, payable semi‑annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2014. The notes mature on December 15, 2018, unless earlier repurchased, redeemed or converted in accordance with their terms. The notes are senior unsecured obligations of the Company and we do not have the right to redeem the notes prior to maturity, except in connection with certain changes in tax laws.

The net proceeds from the convertible note offering were approximately $683 million, after deducting the initial purchasers’ discount and estimated offering expenses.

In 2014, 2015, 2016 and 2017, we repurchased an aggregate of $368.73 million principal amount of the convertible notes for an aggregate of $327.1 million in the open market.

Framework Agreement with Krasnaya Roza 1875 Limited

On February 19, 2016, we entered into a framework agreement with Krasnaya Roza 1875 Limited, a Cypriot company, or KR 1875, for the acquisition of certain buildings in the Krasnaya Roza office complex in central Moscow, in which the Russian headquarters of the Yandex group are located (the “Framework Agreement”). On September 7, 2016, we opted to terminate the Framework Agreement because of changing market conditions. Yandex plans to remain at the Red Rose through the end of the lease term in 2021 but may consider other options for when the lease term expires.

Yandex.Taxi joint venture with Uber

Contribution Agreement with respect to Yandex.Taxi

On July 13, 2017, we entered into a Contribution Agreement (the “Contribution Agreement”) with Uber International C.V. (“Uber”), a wholly owned subsidiary of Uber Technologies, Inc., to combine Yandex.Taxi and the ride-sharing, food delivery and related logistics businesses of Uber in Russia and neighboring countries. On February 7, 2018, the transaction contemplated by the Contribution Agreement closed.

As of December 2017 the combined business operated in Russia, Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan and Moldova.

Pursuant to the Contribution Agreement, the parties contributed their respective businesses within the territories to a newly formed Dutch company, MLU B.V. (“MLU”).  In addition, Yandex contributed $100 million in cash and Uber contributed $225 million in cash to MLU at closing.  Further, Yandex sold Uber an additional 2% stake in MLU in exchange for shares of Class A common stock of Uber.  Following closing, MLU is owned approximately 59,3% by Yandex, 36,9% by Uber, and 3,8% by employees, on a fully diluted basis.

The Contribution Agreement contains warranties, indemnities and covenants customary for a joint venture combination of this nature.

Both parties have licensed their respective brands to MLU for use in the territories.  In addition, Yandex licensed its core maps, location-based services and related technology to MLU.  The MLU business will operate on the existing Yandex.Taxi technology platform, following a transitional period during which riders will be able to use both Yandex and Uber rider-side apps, while the driver-side apps are being integrated.  Uber and MLU have also entered into an agreement to enable their respective riders to roam onto the two companies’ apps when traveling in their respective territories.

Uber granted Yandex a right to require Uber to repurchase the Uber Class A shares received by Yandex in respect of the secondary sale described above, and Uber has a right to require Yandex to sell such Uber shares back to Uber during such period, in each case at an agreed valuation and during an agreed time period.

At closing and in connection with the Contribution Agreement, Yandex and Uber entered into a deed of covenant, pursuant to which each agreed to accept certain restrictive covenants towards MLU in the ride-sharing, food delivery, and related logistics business in the territories for an agreed period, as well as certain non-solicitation restrictions with respect to employees of MLU.

Yandex.Market joint venture with Sberbank

Subscription Agreement with respect to Yandex.Market

On December 12, 2017, we and our wholly owned subsidiary Yandex.Market B.V. entered into a subscription agreement (the “Subscription Agreement”) with Public Joint Stock Company “Sberbank of Russia” (“Sberbank”).

Pursuant to the Subscription Agreement, an affiliate of Sberbank will subscribe for new ordinary shares of Yandex.Market for 30 billion rubles (approximately $500 million as of signing).  Immediately following the closing of the transaction, Yandex and Sberbank will each own approximately 45% of the issued shares in the capital of Yandex.Market (on a fully diluted basis); 10% will be held by an equity incentive foundation to facilitate current and future equity ownership by management and employees of Yandex.Market. The Subscription Agreement contains warranties, indemnities and covenants customary for a transaction of this nature.

Yandex.Market will engage in e-commerce, with a core focus on a B2C online retail marketplace.  In the Russian Federation, other CIS states, Baltics states and Georgia, the principal shareholders will engage in the core business solely through Yandex.Market.

We will continue to provide to Yandex.Market the rights to use the Yandex.Market brand, as well as technology, promotion and related services, all of which on arms’ length terms.  Sberbank or its affiliates will enter into an agreement with Yandex.Market to provide promotion and related services on arms’ length terms.

Shareholders Agreement with respect to Yandex.Market

At the closing of the Yandex.Market joint venture described above, we, Sberbank and Yandex.Market, among others, will enter into a shareholders’ agreement (the “Shareholders’ Agreement”) in respect of the governance and operation of Yandex.Market.  Pursuant to the Shareholders’ Agreement, the board of directors of Yandex.Market will have seven members:  three will be appointed by Yandex (one of whom will be independent of Yandex); three will be appointed by Sberbank (one of whom will be independent of Sberbank); and the fourth will initially be the Chief Executive Officer of Yandex.Market.

Taxation

Taxation in the Netherlands

General

The information set out below is a general summary of the material Dutch tax consequences in connection with the acquisition, ownership and transfer of our Class A shares. The summary does not purport to be a comprehensive description of all the Dutch tax considerations that may be relevant for a particular holder of our Class A shares, who may be subject to special tax treatment under any applicable law, and this summary is not intended to be applicable in respect of all categories of holders of the Class A shares. In particular, this summary is not applicable in respect of any holder who is, is deemed to be or is treated as a resident of the Netherlands for Dutch tax purposes nor to a holder that holds, alone or together with his partner, whether directly or indirectly, the ownership of, or certain other rights over, shares representing 5% or more of our total issued and outstanding capital (or the issued and outstanding capital of any class of shares), or rights to acquire shares, whether or not already issued, that represent at any time 5% or more of our total issued and outstanding capital (or the issued and outstanding capital of any class of shares) or the ownership of, or certain other rights over, profit participating certificates that relate to 5% or more of the annual profit and/or to 5% or more of our liquidation proceeds. Such interest in our Class A shares is further referred to as a Substantial Interest (aanmerkelijk belang).

Please note that under Dutch tax law an individual is considered as a holder of Class A shares as well if he/she is deemed to hold an interest in the Class A shares pursuant to the attribution rules of article 2.14a of the Dutch Income Tax Act 2001, with respect to property that has been segregated, for instance in a trust or a foundation.

The summary is based upon the tax laws of the Netherlands as in effect on the date of this Annual Report, as well as regulations, rulings and decisions of the Netherlands and its taxing and other authorities available on or before such date and now in effect. All references in this summary to the Netherlands and Netherlands law are to the European part of the Kingdom of The Netherlands and its law, respectively, only. All of the foregoing is subject to change, which could apply retroactively and could affect the continuing validity of this summary. As this is a general summary, we recommend that investors or shareholders consult with their own tax advisors as to the Dutch or other tax consequences of the acquisition, ownership and transfer of our Class A shares, including, in particular, the application to their particular situations of the tax considerations discussed below.

The following summary does not address the tax consequences arising in any jurisdiction other than the Netherlands in connection with the acquisition, ownership and transfer of our Class A shares.

Our company currently takes the view that it is a resident of the Netherlands for tax purposes, including for purposes of tax treaties concluded by the Netherlands, and this summary so assumes. This summary further assumes that the holders of Class A shares will be treated for Dutch tax purposes as the absolute beneficial owners of those Class A shares and any dividends (as defined below) received or realized with respect to such shares.

Dividend Withholding Tax

General

Dividends paid on the Class A shares to a holder of such shares are generally subject to Dutch dividend withholding tax at a rate of 15%. The term “dividends” for this purpose includes, but is not limited to:

· distributions in cash or in kind, deemed and constructive distributions, and repayments of paid‑in capital not recognized for Dutch dividend withholding tax purposes;

· liquidation proceeds, proceeds of redemption of shares or, generally, consideration for the repurchase of shares in excess of the average paid‑in capital recognized for Dutch dividend withholding tax purposes;

· the par value of shares issued to a shareholder or an increase of the par value of shares, as the case may be, to the extent that it does not appear that a contribution to the capital recognized for Dutch dividend withholding tax purposes was made or will be made; and

85

· partial repayment of paid‑in capital, recognized for Dutch dividend withholding tax purposes, if and to the extent that there are net profits (zuivere winst), within the meaning of the Dutch Dividend Withholding Tax Act 1965 (Wet op de dividendbelasting 1965), unless the general meeting of our shareholders has resolved in advance to make such a repayment and provided that the par value of the shares concerned has been reduced by a corresponding amount by way of an amendment of our articles of association.

Generally we are responsible for the withholding of taxes at source and the remittance of the amounts withheld to the Dutch tax authorities; the dividend withholding tax will not be for our account.

If we have received a profit distribution from a foreign subsidiary located (a) in a jurisdiction with which the Netherlands has concluded a treaty for the avoidance of double taxation or (b) in Bonaire, St. Eustatius, Saba, Aruba, Curacao or St. Maarten, in which subsidiary we hold at least 25% of the nominal paid‑up capital or if the relevant tax treaty therein provides, we hold at least 25% of the voting rights, which distribution is exempt from Dutch corporate income tax and has been subject to a foreign withholding tax of at least 5%, we are not required to transfer to the Dutch tax authorities the full amount of Dutch dividend withholding tax in respect of dividends distributed by our company. The amount that does not have to be transferred to the Dutch tax authorities can generally not exceed the lesser of (i) 3% of the portion of the dividends distributed by our company that is subject to Dutch dividend withholding tax; and (ii) 3% of the profit distributions our company received from qualifying foreign subsidiaries in the calendar year in which our company distributes the dividends (up to the moment of such dividend distribution) and the two previous calendar years; further limitations and conditions apply.

The amount of Dutch withholding tax that we may retain reduces the amount of dividend withholding tax that we are required to pay to the Dutch tax authorities, but does not reduce the amount of tax we are required to withhold from dividends paid to a holder of our Class A shares. Upon request, a holder of our Class A shares will be notified by our company of the amount of the Dutch withholding tax that was retained by us.

Non‑residents of the Netherlands (including but not limited to U.S. holders)

The following is a description of the material Dutch tax consequences of holders of our Class A shares who under certain circumstances may not be subject to the above described 15% Dutch dividend withholding tax.

Entities (i) that are resident in another EU Member State, in a State of the European Economic Area (the “EEA”) i.e. Iceland, Norway and Liechtenstein, or a country outside the EU/EEA which has an arrangement for the exchange of tax information with the Netherlands; and (ii) that are not subject to taxation by reference to profits in such State, in principle have the possibility to obtain a full refund of Dutch dividend withholding tax, provided such entities would not have been subject to Dutch corporate income tax either had they been resident within the Netherlands, and provided further that such entities do not perform a similar function to that of a tax exempt investment institutions or fiscal investment institutions as referred to in the Dutch Corporate Income Tax Act 1969, and with respect to entities resident in a country outside the EU/EEA which has an arrangement for the exchange of tax information with the Netherlands, provided such entities hold their Class A shares as a portfolio investment, i.e. such shares are not held with a view to the establishment or maintenance of lasting and direct economic links between such holder of Class A shares and our company, and these shares do not allow such holder to effectively participate in the management or control of our company.

Further, a holder of Class A shares who is resident in another EU Member State or in a State of the EEA i.e. Iceland, Norway and Liechtenstein, in principle has the possibility to obtain a refund of Dutch dividend withholding tax, provided that (i) such dividends are not taxable with the holder of Class A shares for personal income tax purposes or corporate income tax purposes and (ii) insofar the Dutch dividend withholding tax exceeds the amount of personal income tax or corporate income tax that would have been due had the holder of Class A shares been resident in the Netherlands, and with respect to a holder of Class A shares resident in a country outside the EU/EEA which has an arrangement for the exchange of tax information with the Netherlands, provided the Class A shares are held by such holder as a portfolio investment, i.e. such shares are not held with a view to the establishment or maintenance of lasting and direct economic links between such holder of Class A shares and our company, and these shares do not allow such holder to effectively participate in the management or control of our company.

A holder of Class A shares who is considered to be a resident of the United States and is entitled to the benefits of the 1992 Double Taxation Treaty between the United States and the Netherlands (“U.S. holder”), as amended most

86

recently by the Protocol signed March 8, 2004 (the “Treaty”) will generally be subject to Dutch dividend withholding tax at the rate of 15% unless such U.S. holder is an exempt pension trust as described in article 35 of the Treaty, or an exempt organization as described in article 36 of the Treaty.

U.S. holders that are exempt pension trusts or exempt organizations as described in articles 35 and 36, respectively, of the Treaty may qualify for an exemption from Dutch withholding tax and may generally claim (i) in the case of an exempt pension trust full exemption at source by timely filing two completed copies of form IB 96 USA signed by the U.S. holder accompanied with U.S. form 6166 (as issued by the U.S. Internal Revenue Service and valid for the relevant tax year) or (ii) in the case of either an exempt pension trust or an exempt organization a full refund by filing through the withholding agent as mentioned in article 9 of the Dutch Dividend Withholding Tax Act 1965 (which is generally the company) one of the following forms signed by the U.S. holder within three years after the end of the calendar year in which the withholding tax was levied:

· if the U.S. holder is an exempt pension trust as described in article 35 of the Treaty: two completed copies of Form IB 96 USA accompanied with U.S. Form 6166 as issued by the U.S. Internal Revenue Service valid for the relevant tax year and

· if the U.S. holder is an exempt organization as described in article 36 of the Treaty: two completed copies of Form IB 95 USA accompanied with U.S. Form 6166 as issued by the U.S. Internal Revenue Service, valid for the relevant tax year.

Taxes on Income and Capital Gains

General

The description of taxation set out in this section of this Annual Report is not intended for any holder of Class A shares who is:

· an individual for whom the income or capital gains derived from the Class A shares are attributable to employment activities the income from which is taxable in the Netherlands; or

· an individual who or an entity which holds, or is deemed to hold, a Substantial Interest in our company (as defined above).

Non‑residents of the Netherlands (including, but not limited to, U.S. holders)

A Non‑Resident of the Netherlands who holds Class A shares is generally not subject to Dutch income or corporate income tax (other than dividend withholding tax described above) on the income and capital gains derived from the Class A shares, provided that:

· such Non‑Resident of the Netherlands does not derive profits from an enterprise or deemed enterprise, whether as an entrepreneur (ondernemer) or pursuant to a co‑entitlement to the net worth of such enterprise (other than as an entrepreneur or a shareholder) which enterprise is, in whole or in part, carried on through a permanent establishment or a permanent representative in the Netherlands or effectively managed in the Netherlands and to which enterprise or part of an enterprise, as the case may be, the Class A shares are attributable or deemed attributable;

· in the case of a Non‑Resident of the Netherlands who is an individual, (a) such individual does not carry out any activities in the Netherlands with respect to the Class A shares that exceed ordinary active asset management (normaal vermogensbeheer), (b) the benefits derived from such Class A shares are not intended as remuneration for activities performed by a holder of Class A shares or by a person connected to such holder as meant by article 3.92b paragraph 5 of the Dutch Income Tax Act 2001 and (c) such individual does not derive income or capital gains from the Class A shares that are taxable as benefits from “other miscellaneous activities” in the Netherlands (resultaat uit overige werkzaamheden in Nederland);

87

· in the case of a Non‑Resident of the Netherlands which is an entity, it is neither entitled to a share in the profits of an enterprise effectively managed in the Netherlands, nor co‑entitled to the net worth of such enterprise, other than by way of the holding of securities, to which enterprise the Class A shares or payments in respect of the Class A shares are attributable; and

· in the case of a Non‑Resident of the Netherlands who is an individual, such individual is not entitled to a share in the profits of an enterprise effectively managed in the Netherlands, other than by way of the holding of securities or, through an employment contract, to which enterprise the Class A shares or payments in respect of Class A shares are attributable.

A U.S. holder that is entitled to the benefits of the Treaty and whose Class A shares are not attributable to a Dutch enterprise or deemed enterprise, will generally not be subject to Dutch taxes on any capital gain realized on the disposal of such Class A shares.

Gift, Estate or Inheritance Taxes

No Dutch gift, estate or inheritance taxes will arise on the transfer of Class A shares by way of a gift by, or on the death of, a holder of Class A shares who is neither resident nor deemed to be resident in the Netherlands, unless in the case of a gift of the Class A shares by an individual who at the date of the gift was neither resident nor deemed to be resident in the Netherlands (i) such individual dies within 180 days after the date of the gift, while being resident or deemed to be resident in the Netherlands; or (ii) the gift of the Class A shares is made under a condition precedent and the holder of these shares is resident, or is deemed to be resident, in the Netherlands at the time the condition is fulfilled.

For purposes of Dutch gift, estate and inheritance taxes, an individual who holds the Dutch nationality will be deemed to be resident in the Netherlands if he or she has been resident in the Netherlands at any time during the ten years preceding the date of the gift or his or her death. Additionally, for purposes of Dutch gift tax, an individual not holding the Dutch nationality will be deemed to be resident in the Netherlands if he or she has been resident in the Netherlands at any time during the twelve months preceding the date of the gift. Applicable tax treaties may override deemed residency.

Value‑Added Tax

There is no Dutch value‑added tax payable in respect of payments in consideration for the sale of the Class A shares (other than value added taxes on fees payable in respect of services not exempt from Dutch value added tax).

Other Taxes and Duties

There is no Dutch registration tax, capital tax, customs duty, stamp duty or any other similar documentary tax or duty other than court fees payable in the Netherlands by a holder of Class A shares in respect of or in connection with the execution, delivery and enforcement by legal proceedings (including any foreign judgment in the courts of the Netherlands) of the Class A shares.

Residence

Other than as set forth above, a holder of Class A shares will not become or be deemed to become a resident of the Netherlands, nor will a holder of Class A shares otherwise become subject to taxation in the Netherlands, solely by reason of holding the Class A shares.

Taxation in the United States

The following summary of the material U.S. federal income tax consequences of the acquisition, ownership and disposition of our Class A shares is based upon current law and does not purport to be a comprehensive discussion of all the tax considerations that may be relevant to a decision to purchase our Class A shares. This summary is based on current provisions of the Internal Revenue Code, existing, final, temporary and proposed United States Treasury Regulations, administrative rulings and judicial decisions, in each case as available on the date of this Annual Report. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax consequences described below.

88

This section summarizes the material U.S. federal income tax consequences to U.S. holders, as defined below, of Class A shares. This summary addresses only the U.S. federal income tax considerations for U.S. holders that hold the Class A shares as capital assets. This summary does not address all U.S. federal income tax matters that may be relevant to a particular U.S. holder, nor does it address any state, local or foreign tax matters or matters relating to any U.S. federal tax other than the income tax. Each investor should consult its own professional tax advisor with respect to the tax consequences of the purchase, ownership and disposition of the Class A shares. This summary does not address tax considerations applicable to a holder of Class A shares that may be subject to special tax rules including, without limitation, the following:

· certain financial institutions;

· insurance companies;

· dealers or traders in securities, currencies, or notional principal contracts;

· tax‑exempt entities;

· regulated investment companies;

· persons that hold the Class A shares as part of a wash sale, hedge, straddle, conversion, constructive sale or similar transaction;

· persons that hold the Class A shares through partnerships or certain other pass‑through entities;

· persons that own (or are deemed to own) 10% or more of our voting shares; and

· persons that have a “functional currency” other than the U.S. dollar.

Further, this summary does not address alternative minimum tax consequences or indirect effects on the holders of equity interests in entities that own our Class A shares. In addition, this discussion does not consider the U.S. tax consequences to non‑U.S. holders of Class A shares.

For the purposes of this summary, a “U.S. holder” is a beneficial owner of Class A shares that is, for U.S. federal income tax purposes:

· an individual who is either a citizen or resident of the United States;

· a corporation, or other entity that is treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state of the United States or the District of Columbia;

· an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

· a trust, if a court within the United States is able to exercise primary supervision over its administration and one or more “United States persons,” within the meaning of the Internal Revenue Code, have the authority to control all of the substantial decisions of such trust.

If a partnership holds Class A shares, the tax treatment of a partner will generally depend upon the status of the partner and upon the activities of the partnership.

We will not seek a ruling from the U.S. Internal Revenue Service (“IRS”) with regard to the U.S. federal income tax treatment of an investment in our Class A shares, and we cannot assure you that that the IRS will agree with the conclusions set forth below.

Distributions.  Subject to the discussion under “Passive Foreign Investment Company Considerations” below, the gross amount of any distribution (including any amounts withheld in respect of Dutch withholding tax) actually or

89

constructively received by a U.S. holder with respect to Class A shares will be taxable to the U.S. holder as a dividend to the extent paid out of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. Distributions in excess of our current and accumulated earnings and profits will be non‑taxable to the U.S. holder to the extent of, and will be applied against and reduce, the U.S. holder’s adjusted tax basis in the Class A shares. Distributions in excess of our current and accumulated earnings and profits and such adjusted tax basis will generally be taxable to the U.S. holder as capital gain from the sale or exchange of property. However, since we do not calculate our earnings and profits under U.S. federal income tax principles, it is expected that any distribution will be reported as a dividend, even if that distribution would otherwise be treated as a non‑taxable return of capital or as capital gain under the rules described above. The amount of any distribution of property other than cash will be the fair market value of that property on the date of distribution. The U.S. holder will not be eligible for any dividends‑received deduction in respect of the dividend otherwise allowable to corporations.

Under the Internal Revenue Code, qualified dividends received by certain non‑corporate U.S. holders (i.e. individuals and certain trusts and estates) currently are subject to a maximum income tax rate of 20%. This reduced income tax rate is applicable to dividends paid by “qualified foreign corporations” to such non‑corporate U.S. holders that meet the applicable requirements, including a minimum holding period (generally, at least 61 days during the 121‑day period beginning 60 days before the ex‑dividend date). We believe that we are a qualified foreign corporation under the Internal Revenue Code. Accordingly, dividends paid by us to non‑corporate U.S. holders with respect to Class A shares that meet the minimum holding period and other requirements are expected to be treated as “qualified dividend income.” However, dividends paid by us will not qualify for the 20% U.S. federal income tax rate cap if we are treated, for the tax year in which the dividends are paid or the preceding tax year, as a “passive foreign investment company” for U.S. federal income tax purposes, as discussed below. Dividends paid by us that are not treated as qualified dividends will be taxable at the normal (and currently higher) ordinary income tax rates, except to the extent that they are taxable otherwise if we are a passive foreign investment company as described below.

Dividends received by a U.S. holder with respect to Class A shares generally will be treated as foreign source income for the purposes of calculating that holder’s foreign tax credit limitation. Subject to applicable conditions and limitations, and subject to the discussion in the next two paragraphs, any Dutch income tax withheld on dividends may be deducted from taxable income or credited against a U.S. holder’s U.S. federal income tax liability. The limitation on foreign taxes eligible for the U.S. foreign tax credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by us generally will constitute “passive category income” (but, in the case of some U.S. holders, may constitute “general category income”).

A “United States person,” within the meaning of the Internal Revenue Code, that is an individual, an estate or a nonexempt trust is generally subject to a 3.8% surtax on the lesser of (i) the United States person’s “net investment income” for the year and (ii) the excess of the United States person’s “modified adjusted gross income” for that year over a threshold (which, in the case of an individual, will be between $125,000 and $250,000, depending on the individual’s U.S. tax filing status). A U.S. holder’s net investment income generally will include, among other things, dividends on, and gains from the sale or other taxable disposition of, our Class A shares, unless (with certain exceptions) those dividends or gains are derived in the ordinary course of a trade or business. Net investment income may be reduced by deductions properly allocable thereto; however, the U.S. foreign tax credit may not be available to reduce the surtax.

Upon making a distribution to shareholders, we may be permitted to retain a portion of the amounts withheld as Dutch dividend withholding tax. See “—Taxation in the Netherlands—Dividend Withholding Tax—General.” The amount of Dutch withholding tax that we may retain reduces the amount of dividend withholding tax that we are required to pay to the Dutch tax authorities but does not reduce the amount of tax we are required to withhold from dividends paid to U.S. holders. In these circumstances, it is likely that the portion of dividend withholding tax that we are not required to pay to the Dutch tax authorities with respect to dividends distributed to U.S. holders would not qualify as a creditable tax for U.S. foreign tax credit purposes.

Sale or other disposition of Class A shares.  A U.S. holder will generally recognize gain or loss for U.S. federal income tax purposes upon the sale or exchange of Class A shares in an amount equal to the difference between the U.S. dollar value of the amount realized from such sale or exchange and the U.S. holder’s tax basis for those Class A shares. Subject to the discussion under “Passive Foreign Investment Company Considerations” below, this gain or loss will be capital gain or loss and will generally be treated as from sources within the United States. Capital gain or loss will be long‑term capital gain or loss if the U.S. holder held the Class A shares for more than one year at the time of the sale or

90

exchange; in general, long‑term capital gains realized by non‑corporate U.S. holders are eligible for reduced rates of tax. The deductibility of losses incurred upon the sale or other disposition of capital assets is subject to limitations.

Passive foreign investment company considerations.  A corporation organized outside the United States generally will be classified as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes in any taxable year in which, after applying the applicable look‑through rules, either: (i) at least 75% of its gross income is passive income, or (ii) at least 50% of the average gross value of its assets is attributable to assets that produce passive income or are held for the production of passive income. In arriving at this calculation, a pro rata portion of the income and assets of each corporation in which we own, directly or indirectly, at least a 25% interest by value, must be taken into account. Passive income for this purpose generally includes dividends, interest, royalties, rents and gains from commodities and securities transactions. We believe that we were not a PFIC for the 2014 and 2015 tax years. Based on estimates of our gross income and the average value of our gross assets, and on the nature of the active businesses conducted by our “25% or greater” owned subsidiaries, we do not expect to be a PFIC in the current taxable year and do not expect to become one in the foreseeable future. However, because our status for any taxable year will depend on the composition of our income and assets and the value of our assets for such year, and because this is a factual determination made annually after the end of each taxable year, there can be no assurance that we will not be considered a PFIC for the current taxable year or any future taxable year. In particular, the value of our assets may be determined in large part by reference to the market price of our Class A shares, which may fluctuate considerably. If we were a PFIC for any taxable year during which a U.S. holder held Class A shares, gain recognized by the U.S. holder on a sale or other disposition (including a pledge) of the Class A shares would be allocated ratably over the U.S. holder’s holding period for the Class A shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the resulting tax liability for that taxable year. Similar rules would apply to the extent any distribution in respect of Class A shares exceeds 125% of the average of the annual distributions on Class A shares received by a U.S. holder during the preceding three years or the holder’s holding period, whichever is shorter. Elections may be available that would result in alternative treatments (such as a mark‑to‑market treatment) of the Class A shares. In addition, if we are considered a PFIC for the current taxable year or any future taxable year, U.S. holders will be required to file annual information returns for such year, whether or not the U.S. holder disposed of any Class A shares or received any distributions in respect of Class A shares during such year.

Backup Withholding and Information Reporting.  U.S. holders generally will be subject to information reporting requirements with respect to dividends on Class A shares and on the proceeds from the sale, exchange or disposition of Class A shares that are paid within the United States or through U.S.‑related financial intermediaries, unless the U.S. holder is an “exempt recipient.” In addition, certain U.S. holders who are individuals may be required to report to the IRS information relating to their ownership of the Class A shares, subject to certain exceptions (including an exception for shares held in an account maintained by a U.S. financial institution). U.S. holders may be subject to backup withholding (currently at 28%) on dividends and on the proceeds from the sale, exchange or disposition of Class A shares that are paid within the United States or through U.S.‑related financial intermediaries, unless the U.S. holder provides a taxpayer identification number and a duly executed IRS Form W‑9 or otherwise establishes an exemption. Backup withholding is not an additional tax and the amount of any backup withholding will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

Documents on Display

We are subject to the periodic reporting and other informational requirements of the Securities Exchange Act of 1934, as amended, or the 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 no later than four months after the close of each fiscal year, which is December 31. Such reports and other information, when so filed, may be accessed at www.sec.gov/edgar or at ir.yandex.com/sec.cfm. 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.

Evaluation of Disclosure Controls and Procedures

The company’s management, with the participation of the company’s chief executive officer and chief financial officer, evaluated the effectiveness of the company’s disclosure controls and procedures as of December 31, 2017. The term “disclosure controls and procedures,” as defined in Rules 13a 15(e) and 15d 15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on the evaluation of the company’s disclosure controls and procedures as of December 31, 2017, the company’s chief executive officer and chief financial officer concluded that, as of such date, the company’s disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate “internal control over financial reporting,” as defined in Rules 13a 15(f) and 15d 15(f) under the Exchange Act. This rule defines internal control over financial reporting as a process designed by, or under the supervision of, a company’s chief executive officer and chief financial officer and effected by its board of directors, management and other personnel, 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 and 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.

Management assessed the design and operating effectiveness of our internal control over financial reporting as of December 31, 2017. This assessment was performed under the direction and supervision of our chief executive officer and chief financial officer, and based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, we concluded that as of December 31, 2017, our internal control over financial reporting was effective.

No change in the company’s internal control over financial reporting occurred during the fiscal year ended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, the company’s internal control over financial reporting.

The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by JSC KPMG, our independent registered public accounting firm. Their report may be found below.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2017, and the related consolidated statements of income, comprehensive income, cash flows, and shareholders’ equity for the year then ended, and the related notes (collectively, the consolidated financial statements), and our report dated March 27, 2018 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’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 are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

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.

Item 16F.  Changes in Registrant’s Certifying Accountant

Management and the Audit Committee of the Board of Directors (the “Audit Committee”) of Yandex N.V. (“Yandex” or the “Company”) have completed a competitive process to review the appointment of the Company’s independent registered public accounting firm for the year ending December 31, 2017. The Audit Committee invited several firms to participate in this process, including ZAO Deloitte & Touche CIS (“Deloitte”).

As a result of this process and following careful deliberation, on May 25, 2017, the Company’s shareholders, pursuant to the recommendation of the Audit Committee, appointed JSC KPMG (“KPMG”), an independent registered public accounting firm and the Russian affiliate of KPMG International, as auditors of the Company’s consolidated financial statements for the 2017 financial year (to be prepared under U.S. GAAP), and KPMG Accountants N.V., its Dutch affiliate, as external auditors of the Company’s statutory annual accounts for the 2017 financial year (to be prepared under IFRS) and Deloitte was discharged on May 25, 2017.

Deloitte’s audit reports on the Company's consolidated financial statements as of and for the years ended December 31, 2016 and 2015 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to audit scope or accounting principles. Such reports included an explanatory paragraph referring to translations of Russian ruble amounts into U.S. dollar amounts presented solely for the convenience of the readers in the United States of America convenience translation.

During the years ended December 31, 2016 and 2015, and the subsequent interim period through May 25, 2017, there were (i) no disagreements with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the subject matter of the disagreements in its reports on the financial statements for such years, and (ii) no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided Deloitte with a copy of this Item 16F disclosure on Form 20-F prior to its filing with the Securities and Exchange Commission (the “SEC”). The Company requested that Deloitte furnish the Company with a letter addressed to the SEC stating whether or not Deloitte agrees with the above statements that are related to Deloitte. A copy of Deloitte’s letter, dated March 27, 2018, is attached hereto as Exhibit 16.

During the years ended December 31, 2016 and 2015 and through May 27, 2017, neither the Company nor anyone on its behalf consulted with KPMG with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and no written report or oral advice was provided by KPMG to the Company that KPMG concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to that Item) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).

Item 16G.  Corporate Governance.

The Sarbanes Oxley Act of 2002, as well as related rules subsequently implemented by the SEC, requires foreign private issuers, including our company, to comply with various corporate governance practices. In addition, NASDAQ rules provide that foreign private issuers may follow home country practice in lieu of the NASDAQ corporate governance standards, subject to certain exceptions and except to the extent that such exemptions would be contrary to

96

U.S. federal securities laws. The home country practices followed by our company in lieu of NASDAQ rules are described below:

· We do not follow NASDAQ’s quorum requirements applicable to meetings of shareholders. In accordance with Dutch law and generally accepted business practice, our articles of association do not provide quorum requirements generally applicable to general meetings of shareholders.

· We do not follow NASDAQ’s requirements regarding the provision of proxy statements for general meetings of shareholders. Dutch law does not have a regulatory regime for the solicitation of proxies and the solicitation of proxies is not a generally accepted business practice in the Netherlands. We do intend to provide shareholders with an agenda and other relevant documents for the general meeting of shareholders.

We intend to take all actions necessary for us to maintain compliance as a foreign private issuer under the applicable corporate governance requirements of the Sarbanes Oxley Act, the rules adopted by the SEC and NASDAQ’s listing standards. As a Dutch company listed on a government recognized stock exchange, we are required to apply the provisions of the Dutch Corporate Governance Code, or explain any deviation from the provisions of such code in our Dutch Annual Report required by Dutch law.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Yandex N.V. and subsidiaries (together, the “Company”) as of December 31, 2017, the related consolidated statements of income, comprehensive income, cash flows, and shareholders’ equity for the year then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and the results of its operations and its cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles.

The accompanying consolidated financial statements as of and for the year ended December 31, 2017 have been translated into United States dollars solely for the convenience of the reader. We have audited the translation and, in our opinion, the consolidated financial statements expressed in Russian rubles have been translated into United States dollars on the basis set forth in Note 2 of the notes to the consolidated financial statements.

We also have audited the adjustments to the 2016 and 2015 consolidated financial statements to retrospectively apply the change in accounting, as described in Note 2. In our opinion, such adjustments are appropriate and have been properly applied. We were not engaged to audit, review, or apply any procedures to the 2016 and 2015 consolidated financial statements of the Company other than with respect to the adjustments and, accordingly, we do not express an opinion or any other form of assurance on the 2016 and 2015 consolidated financial statements taken as a whole.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 27, 2018 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

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, such consolidated financial statements, before the effects of the adjustments to retrospectively apply the change in accounting described in Note 2 to the consolidated financial statements, present fairly, in all material respects, the financial position of Yandex N.V. and subsidiaries as of December 31, 2016, and the results of their operations and their cash flows for the years ended December 31, 2016 and 2015, in conformity with accounting principles generally accepted in the United States of America.

Such U.S. dollar amounts are presented solely for the convenience of readers in the United States of America.

We were not engaged to audit, review, or apply any procedures to the adjustments to retrospectively apply the change in accounting described in Note 2 to the consolidated financial statements and, accordingly, we do not express an opinion or any other form of assurance about whether such retrospective adjustments are appropriate and have been properly applied. Those retrospective adjustments were audited by other auditors.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

1. ORGANIZATION AND DESCRIPTION OF THE BUSINESS

Yandex N.V., together with its consolidated subsidiaries (together, the “Company”), is an internet and technology company and operates Russia’s largest internet search engine. The Company generates substantially all of its revenues from online advertising.

Yandex N.V. was incorporated under the laws of the Netherlands in June 2004 and is the holding company of Yandex LLC, incorporated in the Russian Federation in October 2000, and other subsidiaries.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements differ from the financial statements prepared by the group’s individual legal entities for statutory purposes in that they reflect certain adjustments, not recorded in the accounting records of the group’s individual legal entities, which are appropriate to present the financial position, results of operations and cash flows in accordance with U.S. GAAP. Distributable retained earnings of the Company are based on amounts reported in statutory accounts of individual entities and may significantly differ from amounts calculated on the basis of U.S. GAAP.

Principles of Consolidation

The consolidated financial statements include the accounts of the parent company and the entities it controls. All inter‑company transactions and balances within the Company have been eliminated upon consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and amounts of revenues and expenses for the reporting period. Actual results could differ from those estimates. The most significant estimates relate to fair values of financial instruments, income taxes, impairment assessments of goodwill and intangible assets, useful lives of property and equipment and intangible assets, contingencies, fair values of share-based awards, and accounts receivable allowance. The Company bases its 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.

Reclassifications and changes in presentation

In the first quarter of 2017, Yandex elected to early adopt an ASU “Statement of Cash Flows: Restricted Cash”, which provided revised guidance on the classification and presentation of restricted cash in the statement of cash flows on a retrospective basis. Prior periods have been adjusted accordingly. The effect of the reclassifications is presented below:

Foreign Currency Translation

The functional currency of the Company’s parent company is the U.S. dollar. The functional currency of the Company’s operating subsidiaries is generally the respective local currency. The Company has elected the Russian ruble as its reporting currency. All balance sheet items are translated into Russian rubles based on the exchange rate on the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

balance sheet date and revenue and expenses are translated at monthly weighted average rates of exchange. Translation gains and losses are recorded as foreign currency translation adjustments in other comprehensive income. Foreign exchange transaction gains and losses are included in other income/ (loss), net in the accompanying consolidated statements of income.

Convenience Translation

Translations of amounts from RUB into U.S. dollars for the convenience of the reader have been made at the exchange rate of RUB 57.6002 to $1.00, the prevailing exchange rate as of December 31, 2017. No representation is made that the RUB amounts could have been, or could be, converted into U.S. dollars at such rate.

Certain Risks and Concentrations

The Company’s revenues are principally derived from online advertising, the market for which is highly competitive and rapidly changing. Significant changes in this industry or changes in users’ internet preferences or advertiser spending behavior could adversely affect the Company’s financial position and results of operations.

In addition, the Company’s principal business activities are within the Russian Federation. Laws and regulations affecting businesses operating in the Russian Federation are subject to frequent changes, which could impact the Company’s financial position and results of operations.

Approximately half of the Company’s revenue is collected on a prepaid basis; credit terms are extended to major sales agencies and to larger loyal clients. Accounts receivable are typically unsecured and are primarily derived from revenues earned from customers located in the Russian Federation.

No individual customer or groups of affiliated customers represented more than 10% of the Company’s revenues or accounts receivable in 2015, 2016 and 2017.

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist, in addition to accounts receivable, primarily of cash, cash equivalents, debt securities and term deposits. The primary focus of the Company’s treasury strategy is to preserve capital and meet liquidity requirements.

The Company’s treasury policy addresses the level of credit exposure by working with different geographically diversified banking institutions, subject to their conformity to an established minimum credit rating for banking relationships. To manage the risk exposure, the Company maintains its portfolio of investments in a variety of term deposits, highly‑rated debt instruments issued by financial institutions and money market funds.

Revenue Recognition

The Company recognizes revenues when the services have been rendered, the price is fixed or determinable, persuasive evidence of an arrangement exists, and collectability is reasonably assured. Revenue is recorded net of value added tax (“VAT”).

The Company’s principal revenue streams and their respective accounting treatments are discussed below:

Online Advertising Revenues

The Company’s advertising revenue is generated from serving online ads on its own websites and on Yandex ad network members’ websites. Advance payments received by the Company from advertisers are recorded as deferred

YANDEX N.V.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

revenue on the Company’s consolidated balance sheet and recognized as advertising revenues in the period services are provided.

Advertising sales commissions and bonuses that are paid to agencies are accounted for as an offset to revenues and amounted to RUB 4,113, RUB 5,633 and RUB 7,375 ($128.0) in 2015, 2016 and 2017, respectively.

In accordance with U.S. GAAP, the Company reports advertising revenue gross of fees paid to Yandex ad network members, because the Company is the primary obligor to its advertisers and retains collection risk. The Company records fees paid to ad network members as traffic acquisition costs, a component of cost of revenues.

The Company recognizes online advertising revenue based on the following principles:

The Company’s Yandex.Direct service offers advertisers the ability to place performance-based ads on Yandex and Yandex ad network member websites targeted to users’ search queries or website content. The Company recognizes as revenues fees charged to advertisers as “click‑throughs” occur. A “click‑through” occurs each time a user clicks on one of the performance‑based ads that are displayed next to the search results or on the content pages of Yandex or Yandex ad network members’ websites. The Company’s Yandex.Market services are priced on a cost‑per‑click (CPC) basis, similar to Yandex.Direct. Yandex.Market also operates on a take-rate-based model.

The Company recognizes revenue from brand advertising on its websites and on Yandex ad network member websites as “impressions” are delivered. An “impression” is delivered when an advertisement appears on pages viewed by users.

Other Revenue

The Company’s other revenue primarily consists of commissions for providing ride-sharing services related to the Company’s Yandex.Taxi service. The Company recognizes other revenue in the period the services are provided to the users. For ride-sharing services provided to individual transportation services users, the Company is not a primary obligor and reports only Yandex.Taxi’s commission fees as revenue. For services provided to corporate transportation services clients the Company acts as the primary obligor and revenue and related costs are recorded gross. Promotional discounts to users and minimum fare guarantees are netted against revenues. In case such discounts and minimum fare guarantees exceed the related revenues, the excess is presented in sales, general and administrative expenses in the consolidated statements of income.

The Сompany recorded RUB 9,737 ($169.0) of promotional discounts to users and minimum fare guarantees in 2017 (RUB 2,383 in 2016), of which RUB 4,606 ($80.0) (RUB 592 in 2016) were netted against revenues and RUB 5,131 ($89.1) (RUB 1,791 in 2016) were presented in sales, general and administrative expenses.

Cost of Revenues

Cost of revenues primarily consists of traffic acquisition costs. Traffic acquisition costs consist of amounts ultimately paid to Yandex ad network members and to certain other partners (“distribution partners”) who distribute the Company’s products or otherwise direct search queries to the Company’s websites. These amounts are primarily based on revenue‑sharing arrangements with ad network members and distribution partners. Traffic acquisition costs are expensed as incurred. Cost of revenues also includes expenses associated with the operation of the Company’s data centers, including personnel costs, rent, utilities and bandwidth costs; as well as content acquisition costs and other cost of revenues.

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

Product Development Expenses

Product development expenses consist primarily of personnel costs incurred for the development of, enhancement to and maintenance of the Company’s search engine and other Company’s websites and technology platforms. Product development expenses also include rent and utilities attributable to office space occupied by development staff.

Software development costs, including costs to develop software products, are expensed before technological feasibility is reached. Technological feasibility is typically reached shortly before the release of such products and as a result, development costs that meet the criteria for capitalization were not material for the periods presented.

Advertising and Promotional Expenses

The Company expenses advertising and promotional costs in the period in which they are incurred. For the years ended December 31, 2015, 2016 and 2017, promotional and advertising expenses totaled approximately RUB 2,738, RUB 7,132 and RUB 13,054 ($226.6), respectively.

Government Funds Contributions

The Company makes contributions to governmental pension, medical and social funds on behalf of its employees. In Russia, the amount was calculated using a regressive rate (from 14% to 4% for accredited IT outsourcing providers and from 30% to 15% for other companies in 2017  and from 30% to 15% for all companies in 2015 and 2016) based on the annual compensation of each employee. These contributions are expensed as incurred.

Share‑Based Compensation

The Company grants share options, share appreciation rights (“SARs”), restricted share units (“RSUs”) and business unit equity awards (together, “Share‑Based Awards”) to its employees and consultants.

The Company estimates the fair value at the grant date of share options, SARs and business unit equity awards that are expected to vest using the Black‑Scholes‑Merton (“BSM”) pricing model and recognizes the fair value on a straight‑line basis over the requisite service period. The fair value of RSUs is measured based on the fair market values of the underlying share on the dates of grant.

The assumptions used in calculating the fair value of Share‑Based Awards represent the Company’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s share‑based compensation expense could be materially different in the future. In particular, before the fourth quarter of 2016 the Company was required to estimate the probability that performance conditions that affect the vesting of certain awards would be achieved, and only recognized expense for those shares expected to vest. Starting from the fourth quarter of 2016 the Company accounts for forfeitures as they occur.

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 cannot 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 awards, which comprises (1) the amortization of the incremental portion of share‑based compensation over the remaining vesting term and (2) any unrecognized

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

compensation cost of the original award, using either the original term or the new term, whichever is higher for each reporting period.

Income Taxes

The current provision for income tax is calculated as the estimated amount expected to be recovered from or paid to the tax authorities based on the taxable income for the period.Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets, including operating loss and carryforwards, and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax expense represents the change during the period in the deferred tax assets and deferred tax liabilities. The components of the deferred tax assets and liabilities are individually classified as non‑current. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making such a determination, management consider all available evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations.

The tax benefits of uncertain income tax positions are recognized in the financial statements if it is more likely than not that they will be sustained on audit by the tax authorities, including resolution of related appeals or litigation processes, if any.

Recognized tax benefits are measured as the largest amount that is greater than 50% likely of being realized upon settlement.

The Company recognizes interest and penalties related to unrecognized tax benefits within the provision for income taxes line in the consolidated statements of income. Accrued interest and penalties are presented in the consolidated balance sheets within other accrued liabilities, non-current or accounts payable and accrued liabilities together with unrecognized tax benefits based on the timing of expected resolution.

Comprehensive Income

Comprehensive income is defined as the change in equity during a period from non‑owner sources. U.S. GAAP requires the reporting of comprehensive income in addition to net income. Comprehensive income of the Company includes net income and foreign currency translation adjustments. For the years ended December 31, 2015, 2016 and 2017 total comprehensive income included, in addition to net income, the effect of translating the financial statements of the Company’s legal entities domiciled outside of Russia from these entities’ functional currencies into Russian rubles.

Accumulated other comprehensive income of RUB 896 as of December 31, 2016 and RUB 1,864 ($32.3) as of December 31, 2017 solely comprises cumulative foreign currency translation adjustment.

Redeemable Noncontrolling Interests

Ownership interests in the Company’s consolidated subsidiaries held by the senior employees of these subsidiaries are considered redeemable as according to the terms of the business unit equity awards the employees have the right to redeem their interests for cash. Accordingly, such redeemable noncontrolling interests have been presented as mezzanine equity in the consolidated balance sheets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

Fair Value of Financial Instruments

Financial instruments carried on the balance sheet include cash and cash equivalents, term deposits, restricted cash, investments in debt and equity securities, accounts receivable, loans to employees, accounts payable, accrued liabilities and convertible debt. The carrying amounts of cash and cash equivalents, short-term deposits, current restricted cash, accounts receivable, accounts payable and accrued liabilities approximate their respective fair values due to the short‑term nature of those instruments.

Term Deposits

Bank deposits are classified depending on their original maturity as (i) cash and cash equivalents if the original maturities are three months or less; (ii) current term deposits if the original maturities are more than three months, but no more than one year; and (iii) non‑current term deposits if the original maturities are more than one year.

Investments in Debt Securities

The Company’s investments in debt securities as of December 31, 2016 are classified as held to maturity and are measured and presented at amortized cost, except for credit-linked notes (Notes 5, 7), which are measured and presented at fair value. The interest related to investments in debt securities is reported as a part of interest income in the consolidated statements of income.

Investments in Equity Securities

Investments in the stock of entities in which the Company can exercise significant influence but does not own a majority equity interest or otherwise control are accounted for using the equity method. The Company records its share of the results of these companies within the other income/(loss), net line on the consolidated statements of income. Investments in the non‑marketable stock of entities in which the Company can exercise little or no influence are accounted for using the cost method. Both equity and cost method accounted investments are included in investments in non‑marketable equity securities line on the consolidated balance sheets.

The Company reviews its investments in equity securities for other-than-temporary impairment whenever events or changes in business circumstances indicate that the carrying value of the investment may not be fully recoverable. Investments identified as having an indication of impairment are subject to further analysis to determine if the impairment is other-than-temporary and this analysis requires estimating the fair value of the investment. The determination of fair value of the investment involves considering factors such as current economic and market conditions, the operating performance of the companies including current earnings trends and forecasted cash flows, and other company and industry specific information. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income, net and a new cost basis in the investment is established.

Variable Interest Entities

Entities that do not have sufficient equity at risk to allow the entity to finance its activities without additional financial support or in which the equity investors, as a group, do not have the characteristic of a controlling financial interest are referred to as variable interest entities (“VIE”). A VIE is consolidated by the variable interest holder that is determined to have the controlling financial interest (primary beneficiary) as a result of having both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE’s capital structure, contractual terms, nature of the VIE’s operations and purpose, and the Company’s relative exposure to

F-15

YANDEX N.V.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

the related risks of the VIE on the date it becomes initially involved in the VIE. The Company reassesses its VIE determination with respect to an entity on an ongoing basis.

As of December 31, 2016 and 2017, the Company held interests in a third party, Edadeal, a Russian limited liability company (“Edadeal”) through loans and 10% equity investments. Edadeal is primarily financed by the Company’s loans and operates an application for grocery shopping offers, coupons and cashback. The Company has treated Edadeal as a VIE since Edadeal does not have sufficient equity at risk. The Company has determined that it should not consolidate Edadeal as it is not the primary beneficiary and lacks power through voting or similar rights to direct the activities that most significantly affect Edadeal’s economic performance. The Company’s investments related to Edadeal included in investments in non-marketable equity securities and loans granted to third parties (Note 5) totaled RUB 194 and RUB 361 ($6.3) as of December 31, 2016 and 2017, respectively, representing the Company’s maximum exposure to loss.

Accounts Receivable, Net

Accounts receivable are stated at their net realizable value. The Company provides an allowance for doubtful accounts based on management’s periodic review for recoverability of accounts receivable from customers and other receivables. The Company evaluates the collectability of its receivables based upon various factors, including the financial condition and payment history of major customers, an overall review of collections experience of other accounts and economic factors or events expected to affect the Company’s future collections.

Property and Equipment

Property and equipment are recorded at cost and depreciated over their useful lives. Capital expenditures incurred before property and equipment are ready for their intended use are capitalized as assets not yet in use.

Depreciation is computed under the straight‑line method using estimated useful lives as follows:

	Estimated useful lives
Servers and network equipment	3.0 years
Infrastructure systems	3.0  -  10.0 years
Office furniture and equipment	3.0 years
Buildings	10.0  - 20.0 years
Leasehold improvements	the shorter of 5.0 years or the remaining period of the lease term
Other equipment	3.0 ‑ 5.0 years

Land is not depreciated.

Depreciation of assets included in assets not yet in use commences when they are ready for the intended use.

Goodwill and Intangible Assets

Goodwill represents the excess of purchase consideration over the Company’s share of fair value of the net assets of acquired businesses. During the measurement period, which may be up to one year from the acquisition date, the Company may prospectively apply adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill.  Goodwill is not subject to amortization but is tested for impairment at least annually.

The Company performs a qualitative assessment to determine whether further impairment testing on goodwill is necessary. If the Company believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, a quantitative impairment test is required. Otherwise, no further

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

testing is required. The quantitative impairment test is performed by comparing the carrying value of each reporting unit’s net assets (including allocated goodwill) to the fair value of those net assets. If the reporting unit’s carrying amount is greater than its fair value, the Company recognizes a goodwill impairment charge for the amount by which the carrying value of a reporting unit exceeds its fair value. The Company did not recognize any goodwill impairment for the years ended December 31, 2016 and 2017; in 2015 the Company recognized impairment of RUB 576 related to its earlier KinoPoisk acquisition (Note 9).

The Company amortizes intangible assets using the straight-line method and estimated useful lives of assets ranging from 1 to 10 years, with a weighted‑average life of 5.1 years:

	Estimated useful lives
Acquisition-related intangible assets:
Content and software	1.0-10.0 years
Customer relationships	2.0-10.0 years
Patents and licenses	6.8 years
Non-compete agreements	2.0-5.0 years
Trade names and domain names	2.0-10.0 years
Workforce	4.0 years

The Company evaluates the carrying value of long‑lived assets other than goodwill for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be recoverable. When such a determination is made, management’s estimate of undiscounted cash flows to be generated by the assets is compared to the carrying value of the assets to determine whether impairment is indicated. If impairment is indicated, the amount of the impairment recognized in the consolidated financial statements is determined by estimating the fair value of the assets and recording a loss for the amount by which the carrying value exceeds the estimated fair value. This fair value is usually determined based on estimated discounted cash flows.

Recently Adopted Accounting Pronouncements

In the first quarter of 2017, the Company early adopted an ASU which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statement of cash flows. The amendment should be adopted retrospectively. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements.

Effective December 31, 2017, the Company early adopted an ASU that clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new standard was applied on a prospective basis. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements.

Effective December 31, 2017, the Company early adopted an ASU that simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The new standard was applied on a prospective basis. The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements.

Effective December 31, 2017, the Company early adopted an ASU that amended the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or

conditions of share-based payment awards. The new standard was applied on a prospective basis.The adoption of this ASU did not have a material effect on the Company’s consolidated financial statements.

Effect of Recently Issued Accounting Pronouncements

In May 2014, the FASB issued an ASU on revenue from contracts with customers that will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new guidance (i) removes inconsistencies, and weaknesses in revenue requirements, (ii) provides a more robust framework for addressing revenue issues, (iii) improves comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets, (iv) provides more useful information to users of financial statements through improved disclosure requirements, and (v) simplifies the preparation of financial statements by reducing the number of requirements to which an entity must refer. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. Following amendments in August 2015, the guidance is effective for annual reporting periods beginning after December 15, 2017 including interim periods within that reporting period. The amendments to this guidance issued in March 2016 clarify the implementation guidance on principal versus agent considerations (reporting revenue gross versus net). The Company adopted the standard using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. The cumulative effect of initially applying the standard is recorded as an adjustment to opening retained earnings as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Conpany’s historic accounting under Topic 605. The adoption of ASU 2014-09 did not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows as of the adoption date or for the year ended December 31, 2017.

In January 2016, the FASB issued an ASU amending the guidance on the classification and measurement of financial instruments. Although the guidance retains many current requirements, it significantly revises accounting for (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The ASU also amends certain disclosure requirements associated with the fair value of financial instruments. The adoption of this guidance is effective for reporting periods beginning on or after December 15, 2017 with early adoption permitted for certain provisions of the ASU. The Company is currently evaluating the impact of the new guidance and the method of adoption.

In February 2016, the FASB issued an ASU on accounting for leases which introduces a model that brings most leases on the lessee’s balance sheet. The amendments are effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual reporting periods. Early adoption is permitted. The Company anticipates that the adoption of new standard will materially affect the consolidated balance sheets. The Company is currently evaluating the impact of the new guidance and the method of adoption. Further in January 2018, the FASB has issued an ASU which permits an entity to elect an optional transition practical expedient to not evaluate under new Topic “Leases” land easements that exist or expired before the entity’s adoption of new Topic “Leases” and that were not previously accounted for as leases under current Topic “Leases”. This ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2019, and is currently evaluating the effect that the guidance will have on the consolidated financial statements and related disclosures.

In June 2016, the FASB issued an ASU which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost to be presented at the net amount expected to be collected. The ASU is effective for reporting periods beginning after December 15, 2019. Early adoption is permitted for reporting periods beginning after December 15, 2018. The Company is currently evaluating the effect that this guidance will have on the consolidated financial statements and related disclosures.

In October 2016, the FASB issued an ASU which requires the Company to recognize the income-tax consequences of an intra-entity transfer of an asset other than inventory, when the transfer occurs. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently evaluating the effect that this guidance will have on the consolidated financial statements and related disclosures.

In February 2017, the FASB issued an ASU that clarifies the scope of the derecognition of nonfinancial assets and provides guidance for the partial sales of nonfinancial assets in context of the new revenue standard. The ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2018, and is currently evaluating the effect that the guidance will have on the consolidated financial statements and related disclosures.

In May 2017, the FASB issued an update to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. This ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2018, and is currently evaluating the effect that the guidance will have on the consolidated financial statements and related disclosures.

In July 2017, the FASB issued an ASU which makes limited changes to the Board’s guidance on classifying certain financial instruments as either liabilities or equity. The ASU’s objective is to improve (1) the accounting for instruments with “down-round” provisions and (2) the readability of the guidance in ASC Distinguishing Liabilities From Equity, on distinguishing liabilities from equity by replacing the indefinite deferral of certain pending content with scope exceptions. This ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2019, and is currently evaluating the effect that the guidance will have on the consolidated financial statements and related disclosures.

In August 2017, the FASB issued amendments to hedge accounting intended to better align a company's risk management strategies and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The amendments expand and refine accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and hedged item in the financial statements. This ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2019, and is currently evaluating the effect that the guidance will have on the consolidated financial statements and related disclosures.

In September 2017, the FASB has issued an ASU “Revenue Recognition”, ASU “Revenue from Contracts with Customers” and ASU “Leases”: Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments.” This ASU is effective upon adoption of ASC “Revenue from Contracts with Customers” and ASC “Leases”. The Company is still in the process of evaluating the impact of adopting this new accounting standard on its financial statements and related disclosures.

In November 2017, the FASB has issued an ASU that amends various paragraphs in ASC “Income Statement – Reporting Comprehensive Income”, ASC “Revenue Recognition” and ASC “Revenue from Contracts with Customers” that contain SEC guidance. This ASU is effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2018, and is currently evaluating the effect that the guidance will have on the consolidated financial statements and related disclosures.

In February 2018, the FASB issued an ASU that amending the guidance on the reclassification of certain tax effects from accumulated other comprehensive income in ASC “Income Statement – Reporting Comprehensive Income”. The ASU required a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate as a result of the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the historical corporate income tax rate and the newly enacted twenty-one percent corporate income tax rate. The ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company currently anticipates adopting the standard effective January 1, 2018, and is currently evaluating the impact that the guidance will have on the consolidated financial statements.

In February 2018, the FASB issued an ASU “Technical Corrections and Improvements to Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities”. This ASU was issued to clarify certain narrow aspects of guidance concerning the recognition of financial assets and liabilities established in ASU “Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. This includes an amendment to clarify that an entity measuring an equity security using the measurement alternative may change its measurement approach to a fair valuation method in accordance with Topic “Fair Value Measurement”, through an irrevocable election that would apply to that security and all identical or similar investments of the same issued. This ASU is effective for reporting periods beginning after December 15, 2017 and interim periods within those fiscal years beginning after June 15, 2018.

3. NET INCOME PER SHARE

Basic net income per Class A and Class B ordinary share for the years ended December 31, 2015, 2016 and 2017 is computed on the basis of the weighted average number of ordinary shares outstanding using the two class method. Basic net income per share is computed using the weighted average number of ordinary shares outstanding during the period, including restricted shares. Diluted net income per ordinary share is computed using the effect of the outstanding Share‑Based Awards calculated using the “treasury stock” method.

The computation of the diluted net income per Class A share assumes the conversion of Class B shares, while the diluted net income per Class B share does not assume the conversion of those shares. The net income per share amounts are the same for Class A and Class B shares because the holders of each class are legally entitled to equal per share distributions whether through dividends or in liquidation. The number of Share‑Based Awards excluded from the diluted net income per ordinary share computation, because their effect was anti-dilutive for the years ended December 31, 2015, 2016 and 2017, was 4,652,546, 2,362,417 and 1,862,125, respectively. The effects of Business Unit Equity Awards were excluded from the diluted net income per ordinary share computation for the years ended December 31, 2015 and 2016, because the effects were anti-dilutive. The effects of Business Unit Equity Awards were excluded from the diluted net income per ordinary share computation for the year ended December 31, 2017, because the effects were not significant.

The Company’s outstanding convertible debt provides for a flexible settlement feature. The Company intends to settle upon conversion the principal amount of the debt for cash and the conversion premium for Class A shares. The convertible debt is included in the calculation of diluted net income per share if its inclusion is dilutive under the treasury stock method. The convertible debt was anti‑dilutive in the years ended December 31, 2015, 2016 and 2017.

4. BUSINESS COMBINATIONS AND INVESTMENT TRANSACTIONS

Acquisitions in 2017

Shkulev

In June 2017, the Company completed the acquisition of assets and assumption of liabilities of Hearst Shkulev Digital LLC (“Shkulev”),one of the biggest regional auto classifieds with the leading position in Sverdlovsk and Chelyabinsk regions of the Russian Federation, for a cash consideration of RUB 401 ($7.0), including a contingent consideration of RUB 52 ($0.9), subject to successful technical integration and client base transition. The Company accounted for the acquisition as a business combination.

	RUB
ASSETS:
Intangible assets	59
Deferred tax assets	68
Goodwill	274
Total assets	401
Net assets	401
Total purchase consideration	401

The RUB 274 ($4.8) assigned to goodwill is attributable to the Classifieds reportable segment and primarily arises due to specific synergies that result from convergence with other vertical aggregators developed by the Company and the Company’s distribution capabilities. Of the RUB 59 ($1.0) assigned to intangible assets, approximately RUB 22  ($0.4) relates to software and website, RUB 12 ($0.2) domain name and trademark, RUB 10 ($0.2) relates to customer relationships and RUB 15 ($0.2) represents non-compete agreements.

The results of operations of Shkulev for the period prior to acquisition would not have had a material impact on the Company’s results of operations for the years ended December 31, 2016 and 2017. Accordingly, no pro forma financial information is presented. The results of operations of Shkulev did not have a material impact on the Company’s results of operations for the year ended December 31, 2017.

FoodFox

In December 2017, the Company completed the acquisition of a 100% ownership interest in Deloam Management Limited and its subsidiary (“FoodFox”). FoodFox is one of the leading food delivery operators in Moscow. The primary purpose of the acquisition of FoodFox was to enlarge the range of services provided by the Company. The fair value of consideration transferred totaled RUB 595 ($10.3) and consisted of cash consideration of RUB 541 ($9.4) and deferred consideration of RUB 54 ($0.9). The deferred consideration arrangement requires the Company to pay the additional cash consideration to FoodFox’s former shareholders and convertible debt holders, when certain legal conditions are being met within one-year period.

Other non-current liabilities	115
Deferred tax liabilities	16
Total liabilities	151
Net assets	595
Total purchase consideration	595

The RUB 639 ($11.1) assigned to goodwill is attributable to the Taxi reportable segment and primarily arises due to expected synergies and the assembled workforce of FoodFox that does not qualify for separate recognition. None of the goodwill is expected to be deductible for income tax purposes. As of 31 December 2017, there were no changes in the recognized amount of goodwill resulting from the acquisition of FoodFox. Of the RUB 82 ($1.4) assigned to intangible assets, approximately RUB 63 ($1.1) relates to software that will be amortized over a period of 5.0 years. The remaining RUB 19 ($0.3) was assigned to client relationships.

The results of operations of FoodFox for the period prior to acquisition would not have had a material impact on the Company’s results of operations for the year ended December 31, 2016. Accordingly, no pro forma financial information is presented.

The pro forma consolidated income statement as if had been included in the consolidated results of the Company for the year ending December 31, 2017, would include revenue in the amount of RUB 104 ($1.8) and net loss in the amount of RUB 409 ($7.1).  These amounts have been calculated after applying the Company’s accounting policies and adjusting the results of FoodFox to reflect the additional amortization that would have been charged assuming the fair value adjustments to intangible assets had been applied on January 1, 2017, together with the consequential tax effects.

The results of operations of FoodFox after acquisition for the period since December 22, 2017 to December 31, 2017 did not have a material impact on the Company’s results of operations for the year ended December 31, 2017.

Other

During the year ended December 31, 2017, the Company completed another acquisition for total consideration of approximately RUB 66 ($1.1). In aggregate, RUB 30 ($0.5) was attributed to intangible assets, RUB 29 ($0.5) was attributed to goodwill and RUB 7 ($0.1) was attributed to deferred tax assets. Goodwill is attributable to the Classifieds reportable segment and primarily arises due to specific synergies that result from convergence with other vertical aggregators developed by the Company and the Company’s distribution capabilities.

	RUB
ASSETS:
Intangible assets	114
Deferred tax assets	77
Goodwill	224
Total assets	415
Net assets	415
Total purchase consideration	415

The RUB 224 assigned to goodwill is attributable to the Taxi reportable segment and primarily arises due to specific synergies that result from convergence with the Company’s technologies. Of the RUB 114 assigned to intangible assets, approximately RUB 93 relates to client relationships that will be amortized over a period of 5.0 years. The remaining RUB 21 assigned to intangible assets represents non-compete agreements of RUB 12 and software of RUB 9. The Company has not included in the purchase consideration the contingent payment of up to RUB 500 related to the number of qualifying taxi trips but instead recorded it as compensation expense on a straight-line basis as the sellers completed their requisite service periods.

ASSETS:
Intangible assets	58
Deferred tax assets	12
Goodwill	50
Total assets	120
Net assets	120

The remaining RUB 8 assigned to intangible assets represents domain name and trademark.

The Company had not included in the purchase consideration the contingent cash payment of up to RUB 60 and contingent RSU grants up to RUB 20 to the sellers that were subject to attaining certain implementation and integration milestones. These were recorded as a compensation expense on a straight-line basis in 2016 as the sellers completed their requisite service periods.

The Company retained a noncontrolling interest (25% plus one ruble) and significant influence over Yandex.Money's business; accordingly, the Company accounts for its investment under the equity method. The Company records its share of the results of the investee in the amount of income of RUB 217 and income of RUB 374  ($6.5) for the years ended December 31, 2016 and 2017, respectively, within the other income/(loss), net line in the consolidated statements of income.

6. DERIVATIVE AND NON-DERIVATIVE FINANCIAL INSTRUMENTS

The Company does not enter into derivative arrangements for hedging, trading or speculative purposes. However, some of the Company’s contracts have embedded derivatives that are bifurcated and accounted for separately from the host agreements. None of these derivatives are designated as hedging instruments.

The Company recognizes such derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets at fair value and records changes in the fair value of the derivatives in the accompanying consolidated statements of income as other income/(loss), net.

The fair value of derivative instruments as of December 31, 2016 and 2017 is as follows:

	Balance Sheet Location	2016	2017	2017
		RUB	RUB	$
Foreign exchange contracts	Other accrued liabilities	59	18	0.3
Total derivative liabilities		59	18	0.3

The effect of derivative instruments not designated as hedging instruments on income for the years ended December 31, 2015, 2016 and 2017 amounted to a loss of RUB 55, a gain of RUB 33 and a gain of RUB 41 ($0.7), respectively.

The Company uses non-derivative financial instruments to protect the Company from risk that the U.S. dollar-denominated Moscow office rent expenses will be adversely affected by changes in the exchange rates and to avoid income statement volatility. In March 2017, the Company designated $102.8 (RUB 5,976 at the exchange rate as of the date of designation) of its U.S. dollar-denominated deposits with a third party bank as a hedging instrument to hedge the foreign currency exposure to changes in the fair value of the unrecognized firm commitment on its Moscow headquarters operating lease arrangements. The change in fair value of the designated portion of the U.S. dollar-denominated deposits due to changes in foreign currency exchange rates is recognized in other income/(loss), net in the consolidated statements of income along with the change in the fair value of the unrecognized firm commitment that is attributable to foreign currency exchange rates. The change in fair value of the unrecognized firm commitment is included within other current assets on the balance sheet and amounted to RUB 31 ($0.5) as of December 31, 2017.

The fair value of non-derivative financial instruments designated as hedging instruments as of December 31, 2016 and 2017 amounted to nil and RUB 2,731 ($47.4),  respectively, and is included within current term deposits on the balance sheet.

7. FAIR VALUE MEASUREMENTS

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A three‑tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:

Level 1—observable inputs that reflect quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2—inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and

Level 3—inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Company measures the fair value of non-current term deposits and convertible debt for disclosure purposes. The carrying amounts and fair values of non-current term deposits and convertible debt as of December 31, 2016 and 2017 were as follows:

	2016		2017
	Carrying amount	Fair value	Carrying amount		Fair value

Total	(18,750)	(19,228)	(12,829)	(222.7)	(13,310)	(231.1)

The Company did not estimate the fair value of non‑marketable equity investments carried at cost because it did not identify events or changes in circumstances that might have had a significant adverse effect on the fair value of these investments. Furthermore, the Company believes it is not practicable to estimate the fair value of these equity investments since quoted market prices are not available and the cost of obtaining independent valuations appears excessive considering the materiality of the investments to the Company.

In the year ended December 31, 2015, the Company recorded goodwill impairment in the amount of RUB 576 related to the KinoPoisk acquisition in 2013 (included in Experiments) which is the amount by which the carrying value of goodwill exceeded its implied fair value. Goodwill impairment was a result of a combination of factors, including adverse changes in the business climate in Russia subsequent to the acquisition, higher than expected competition in the Russian online media services sector and the resulting decrease in the projected operating results. Fair value was determined using cash flow projections based on financial budgets covering a five-year period. The cash flows beyond that five-year period have been estimated based on sustainable long-term growth rates.

Goodwill is non-deductible for tax purposes for all business combinations completed in the years ended December 31, 2015, 2016 and 2017.

As of December 31, 2017, Yandex N.V. had net operating loss carryforwards (“NOLs”) for Dutch income tax purposes of RUB 1,825 ($31.7). These NOLs expire in the 2025-2026 tax years. As of December 31, 2017, a benefit of RUB 210 ($3.6) related to the Dutch NOLs described above would be recorded by the Company in additional paid‑in capital if and when realized.

The Company did not provide for dividend withholding taxes on the unremitted earnings of its foreign subsidiaries in 2012 and earlier years because they were considered indefinitely reinvested outside of the Netherlands.

Starting in 2014, the Company began to accrue for a 5% dividend withholding tax on the portion of the current year profit of the Company’s principal Russian operating subsidiary that is considered not to be indefinitely reinvested in Russia. The Company also provided in 2017 for a 5% dividend withholding tax on the portion of the profit for 2013 of the Company’s principal Russian operating subsidiary that was considered not to be indefinitely reinvested in Russia. As of December 31, 2017, the amount of unremitted earnings upon which dividend withholding taxes have not been provided is approximately RUB 58,795 ($1,020.7). The Company estimates that the amount of the unrecognized deferred tax liability related to these earnings is approximately RUB 2,940 ($51.0).  

The tax years 2015-2017 remain open for examination by the Russian tax authorities with respect to the Company’s principal Russian operating subsidiary, Yandex LLC. As of December 31, 2017, Yandex LLC was under audit by tax inspectorates for the tax years 2015-2016. The tax years 2013-2017 remain open for examination by the Dutch tax authorities with respect to Yandex N.V.

11. CONVERTIBLE DEBT

In December 2013, the Company issued and sold $600.0 (RUB 19,719 at the exchange rate as of sale date) in aggregate principal amount of 1.125% convertible senior notes due December 15, 2018 at par. The Company also granted to the initial purchasers a right to purchase up to an additional $90.0 (RUB 2,981 at the exchange rate as of sale date) in aggregate principal amount of notes solely to cover over‑allotments. In January 2014, the Company issued and sold an additional $90.0 in aggregate principal amount of 1.125% convertible senior notes due December 15, 2018 (together, the “Notes”) at par. Interest at an annual rate of 1.125% is payable semi‑annually on June 15 and December 15 of each year, beginning on June 15, 2014. The Notes are convertible into cash, Class A shares of the Company or a combination of cash and Class A shares, at the Company’s election, under circumstances described below, based on an initial conversion rate of 19.44 Class A shares per $1,000 principal amount of Notes (which represents an initial conversion price of approximately $51.45 per share), subject to adjustment on the occurrence of fundamental change as defined in the agreement. The Notes are convertible, at the option of the holder, prior to June 15, 2018, if i) the last reported sale price of the Class A shares for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days is greater than or equal to 130% of the conversion price on each applicable trading day; ii) during a 5 business day period after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s Class A shares and the conversion rate on each such trading day; iii) upon the occurrence of specified corporate events. On or after June 15, 2018, the Notes can be converted at the option of the holder regardless of the foregoing circumstances at any time until the close of business on the business day immediately preceding the maturity date of the Notes. The Company will not have the right to redeem the Notes prior to maturity, except in connection with certain changes in tax laws. As of December 31, 2017, none of the conditions allowing the conversion of the Notes had been met.

The net proceeds to the Company from the sale of the Notes (including over‑allotments) were approximately RUB 22,479 ($683.1 at the exchange rates as of sale date). Debt issuance costs were approximately RUB 228 ($4.1), of which RUB 38 ($0.7) was allocated to additional paid‑in capital and RUB 190 ($3.4) was allocated to deferred issuance costs which are presented as a reduction of the carrying value of the Notes and will be amortized as interest expense over the term of the Notes. As of December 31, 2016 and 2017, unamortized deferred issuance cost was RUB 65 and RUB 29 ($0.5), respectively.

The Company separately accounts for the liability and equity components of the Notes. The carrying value of the liability component of RUB 18,972 ($576.7 at the exchange rates as of sale date) was initially recognized at the present value of its cash flows using a discount rate of 4.84%, the Company’s estimated borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. Debt discount is amortized using the effective interest method over the period from the origination date through the stated maturity date. The value of the equity component of RUB 3,728 ($113.3 at the exchange rates as of sale date) was calculated by deducting the fair value of the

liability component from the initial proceeds ascribed to the convertible debt instrument as a whole and was recorded as a debt discount.

During 2017, the Company repurchased and retired $12.0 in aggregate principal amount of the outstanding Notes for cash consideration of RUB 668 ($11.6); during 2016, the Company repurchased and retired $87.4 in aggregate principal amount of the outstanding Notes for cash consideration of RUB 5,397; during 2015, the Company repurchased and retired $119.4 in aggregate principal amount of the outstanding Notes for cash consideration of RUB 6,096. The Company recorded a loss of RUB 6 ($0.1), gain of RUB 53 and gain of RUB 310 on the extinguishment of the debt within the other income/(loss), net line in the consolidated statements of income for the years ended December 31, 2017, 2016 and 2015, respectively.

The carrying value of the Notes as of December 31, 2016 and 2017 consisted of the following:

	2016	2017	2017
	RUB	RUB	$
1.125% Convertible Senior Notes due December 2018	20,211	18,507	321.3
Unamortized debt discount	(1,396)	(644)	(11.2)
Unamortized debt issuance cost	(65)	(29)	(0.5)
Total convertible debt	18,750	17,834	309.6

The remaining unamortized debt discount of RUB 644 ($11.2) as of December 31, 2017 will be amortized over the remaining life of the Notes, which is approximately 1.0 year.

The Company recognized RUB 1,293, RUB 1,208 and RUB 897 ($15.6) as interest expenses related to the contractual interest coupon, amortization of the debt discount and issuance expenses for the years ended December 31, 2015, 2016 and 2017, respectively. The effective interest rate on the liability component for the 2015 –2017 period was 5.1%.

12. COMMITMENTS AND CONTINGENCIES

Lease and Other Commitments

In December 2008, the Company signed an agreement for a ten‑year lease of office space in Moscow. In April 2011, the Company entered into two more lease agreements to increase the size of its rented office space located in its headquarters complex in Moscow for the remaining period of the original lease. In April 2014, the Company further extended its headquarters complex signing a seven‑year lease agreement for additional office space and extending the existing rent agreements to 2021. In December 2016 and during 2017 the Company signed additional agreements to rent additional office space in Moscow until the end of 2021.

2022 and thereafter	—	519	519	9.0
Total	15,277	2,237	17,514	304.1

For the purposes of the disclosure above, the Company assumed no changes in the rented space or rental price specified in existing rental agreements as of the reporting date. U.S. dollar amounts have been translated into Ruble at a rate of RUB 57.6002 to $1.00, the official exchange rate quoted as of December 31, 2017 by the Central Bank of the Russian Federation.

For the years ended December 31, 2015, 2016 and 2017, rent expenses under operating leases totaled approximately RUB 4,372, RUB 4,419 and RUB 4,208 ($73.1), respectively.

Additionally, the Company has entered into purchase commitments for other goods and services and acquisition of businesses, which total RUB 3,285 ($57.0) in 2018, RUB 1,432 ($24.9) in 2019, RUB 1,196 ($20.8) in 2020, RUB 618 ($10.7) in 2021, RUB 5 ($0.1) in 2022 and RUB 3 ($0.1) thereafter.

Legal Proceedings

In the ordinary course of business, the Company is a party to various legal proceedings, and subject to claims, certain of which relate to copyright infringement, as well as to the alleged breach of certain contractual arrangements. The Company intends to vigorously defend any lawsuit and believe that the ultimate outcome of any pending litigation, other legal proceedings or other matters will have no material adverse effect on financial condition, results of operations or liquidity of the Company.

As of December 31, 2017, the Company was subject to certain claims in the aggregate claimed amount of approximately RUB 1,967 ($34.2). The Company has not recorded a liability in respect of those claims as of December 31, 2017.

Environment and Current Economic Situation

The Company’s operations are primarily located in the Russian Federation. Consequently, the Company is exposed to the economic and financial markets of the Russian Federation which display characteristics of an emerging market. The legal, tax and regulatory frameworks continue development, but are subject to varying interpretations and frequent changes which together with other legal and fiscal impediments contribute to the challenges faced by entities operating in the Russian Federation.

In particular, taxes are subject to review and investigation by a number of authorities authorized by law to impose fines and penalties. Although the Company believes it has provided adequately for all tax liabilities based on its understanding of the tax legislation, the above factors may create tax risks for the Company. In addition to the obligations shown in the lease commitments section above, approximately RUB 290 ($5.0) of unrecognized tax benefits have been recorded as liabilities, and the Company is uncertain as to if or when such amounts may be settled (Note 10).

FOR THE YEARS ENDED DECEMBER 31, 2015, 2016 AND 2017

(in millions of Russian rubles and U.S. dollars, except share and per share data)

Related to unrecognized tax benefits, the Company has also recorded a liability for potential penalties of RUB 48 ($0.8) and interest of RUB 69 ($1.2). As of December 31, 2017, except for the income tax contingencies described above, the Company accrued RUB 653 ($11.3) for contingencies related to non‑income taxes, including penalties and interest. Additionally, the Company has identified possible contingencies related to non-income taxes, which are not accrued. Such possible non-income tax contingencies could materialize and require the Company to pay additional amounts of tax. As of December 31, 2017, the Company estimates such contingencies related to non-income taxes, including penalties and interest, to be up to approximately RUB 957 ($16.6).

Because Russia produces and exports large volumes of oil and gas, its economy is particularly sensitive to the price of oil and gas on the world market. In 2014 and 2015, Russia experienced an economic downturn characterized by substantial depreciation of its currency, sharp fluctuations of interest rates, a decline in disposable income, a steep decline in the value of shares traded on its stock exchanges, a material increase in the inflation rate, and a decline in the gross domestic product. In 2016 and through the first months of 2017 some of those economic trends reversed or moderated, with ruble strengthening, oil prices increasing, inflation rates declining significantly and rate of decline in gross domestic product moderating. In February 2018 Standard & Poor’s changed the outlook for Russia’s sovereign credit ratings from negative (BB+) to stable (BBB-).

The conflict in Ukraine and related events have increased the perceived risks of doing business in the Russian Federation. The imposition of economic sanctions on Russian individuals and legal entities by the European Union, the United States of America, Japan, Canada, Australia and others, as well as retaliatory sanctions imposed by the Russian government, have resulted in increased economic uncertainty including more volatile equity markets, a depreciation of the Russian Ruble, a reduction in both local and foreign direct investment inflows and a significant tightening in the availability of credit. In particular, some Russian entities may be experiencing difficulties in accessing international equity and debt markets and may become increasingly dependent on Russian state banks to finance their operations. The longer term effects of recently implemented sanctions, as well as the threat of additional future sanctions, are difficult to determine.

The above mentioned events have led to reduced access of Russian businesses to international capital markets, increased inflation, economic recession and other negative economic consequences. The impact of further economic developments on future operations and financial position of the group is at this stage difficult to determine.

13. SHARE CAPITAL

The Company has three authorized classes of ordinary shares, Class A, Class B and Class C with €0.01, €0.10 and €0.09 par value, respectively. The principal features of the three classes of ordinary shares are as follows:

· Class A shares, par value €0.01 per share, entitled to one vote per share. The Class A shares share ratably with the Class B shares, on a pari passu basis, in any dividends or other distributions.

· Class B shares, par value €0.10 per share, entitled to ten votes per share. Class B shares may only be transferred to qualified holders. In order to sell a Class B share, it must be converted into a Class A share.

· Class C shares, par value €0.09 per share, entitled to nine votes per share. The Class C shares are entitled to a fixed nominal amount in the event of a dividend or distribution limited to €0.01 per share in any one financial year if any such shares were to be outstanding on the record date for a dividend declaration. The Class C shares are used for technical purposes related to the conversion of Class B shares into Class A shares. During the periods between conversion and cancellation, all Class C shares are held by Yandex Conversion Foundation (Stichting Yandex Conversion). Yandex Conversion Foundation was incorporated under the laws of the Netherlands in October 2008 for the sole purpose of facilitating the conversion of

Class B shares into Class A shares. Yandex Conversion Foundation is managed by a board of directors appointed by the Company.

On September 21, 2009, the Company issued a Priority Share to Sberbank. The holder of the Priority Share has the right to veto the accumulation of stakes in the Company in excess of 25% by a single entity, a group of related parties or parties acting in concert. The holder of the Priority Share does not have any rights to influence operating decisions of the Company nor is it entitled to a seat on the Company’s Board. Transfer of the Priority Share requires the approval of the Board. The Priority Share has been purchased by Sberbank at its par value of €1 and is entitled to a normal pro rata dividend distribution.

The Company’s articles of association authorize a special class of preference shares as a form of an anti‑takeover defense. The Company’s Board has the irrevocable authority for a period of five years to issue preference shares and grant rights to subscribe for preference shares up to the Company’s authorized share capital from time to time. This authority may be renewed by a resolution of the general meeting of shareholders for a subsequent period of up to five years. The preference shares, if issued, would be entitled to receive preferential dividends at a rate of 12-month EURIBOR plus 200 basis points on the amount paid thereon, prior and in preference to distributions in respect of ordinary shares. No preference shares have been issued.

The share capital as of each balance sheet date is as follows (EUR in millions):

	December 31, 2016				December 31, 2017
	Shares	EUR		RUB	Shares	EUR		RUB

Class C ordinary shares	560,235		0.1	3	4,166,448		0.3	26

Class C shares held in treasury are not disclosed as such due to the technical nature of this class of shares.

The Company repurchases its Class A shares from time to time in part to reduce the dilutive effects of its Share‑Based Awards to employees of the Company. There were no repurchases in the years ended December 31, 2015, 2016 and 2017. Treasury stock is accounted for under the cost method.

14. REDEEMABLE NONCONTROLLING INTERESTS

Redeemable noncontrolling interests relate to the equity incentive arrangements the Company has made available to the senior employees of the Taxi, Classifieds and E-commerce business units, pursuant to which such persons are eligible to acquire depositary receipts, or receive options to acquire depositary receipts, which entitle them to economic interests in the respective subsidiaries of the Company.

The noncontrolling interests relating to the depositary receipts acquired by the senior employees were measured at the redemption value and amounted to RUB 631 and RUB 2,497 ($43.3) as of December 31, 2016 and 2017,

respectively. The noncontrolling interests relating to the options to acquire depositary receipts were measured at the redemption value and amounted to RUB 875 and RUB 7,324 ($127.2) as of December 31, 2016 and 2017, respectively.

15. SHARE‑BASED COMPENSATION

Employee Equity Incentive Plan

The Company has granted Share‑Based Awards to employees of the Company pursuant to its Fourth Amended and Restated 2007 Equity Incentive Plan (the “2007 Plan”) and the 2016 Equity Incentive Plan (the “2016 Plan,” and together with the 2007 Plan, the “Plans”).

On February 7, 2007, the Company’s Board adopted the 2007 Plan, which superseded the previous 2001 Employee Share Option Plan, and subsequently amended the 2007 Plan on October 11, 2007, October 14, 2008, November 10, 2011, February 10, 2012, and July 24, 2013. The 2016 Plan was approved at the 2016 annual general meeting of shareholders on May 27, 2016 and replaced the 2007 Plan.  However, there remain unexercised grants under the 2007 Plan. A share option issued under the Plans entitles the holder to purchase an ordinary share at a specified exercise price. SARs issued under the Plans entitle the holder to receive a number of Class A shares determined by reference to appreciation from and after the date of grant in the fair market value of a Class A share over the measurement price. RSUs awarded under the Plans entitle the holder to receive a fixed number of Class A shares at no cost upon the satisfaction of certain time‑based vesting criteria. The holders of RSUs have no rights to dividends or dividends equivalent. The 2016 Plan provides for the issuance of Share‑Based Awards to employees, officers, advisors and consultants of the Company and members of the Board of the Company to acquire or, in regard to SARs, to benefit from the appreciation of ordinary shares representing in the aggregate a maximum of 15% of the issued share capital of the Company.

Under the Plans, the award exercise or measurement price per share is set at the “fair market value” and denominated in U.S. dollars on the date the Share-Based Awards are granted by the Company’s Board. For purposes of the Plans, “fair market value” means (A) at any time when the Company’s shares are not publicly traded, the price per share most recently determined by the Board to be the fair market value; and (B) at any time when the shares are publicly traded, (i) in the case of RSUs, the closing price per Class A Share (as adjusted to account for the ratio of shares to depositary shares, if necessary) on the date of such determination; and (ii) in the case of Options and Share Appreciation Rights, the average closing price per Class A Share (as adjusted to account for the ratio of Class A Shares to such depositary shares, if necessary) on the 20 trading days immediately following the date of determination. Share-Based Awards granted under the Plans generally vest over a four‑year period. Approximately 25% of the Share‑Based Awards vest after one year, with the remaining Share‑Based Awards vesting in equal amounts on the last day of each quarter over the following three years. If a grantee ceases to be an eligible participant within three months following the consummation of a change of control because of termination by the grantee for good reason or because of termination by the Company for any reason other than for cause, the Share‑Based Award(s) held by such grantee shall become fully vested and immediately exercisable. The maximum term of a Share‑Based Award granted under the Plans may not exceed ten years. The 2016 Plan expires at midnight on May 27, 2026. After its expiration, no further grants can be made under the 2016 Plan but the vesting and effectiveness of Share‑Based Awards previously granted will remain unaffected.

(in millions of Russian rubles and U.S. dollars, except share and per share data)

The Company estimates the fair value of share options and SARs using the BSM pricing model. The weighted average assumptions used in the BSM pricing model for grants made under the 2016 Plan in the year ended December 31, 2017 were as follows:

	2017
Dividend yield		—
Expected annual volatility		40	%
Risk-free interest rate		2.23	%
Expected life of the awards (years)		7.19
Weighted-average grant date fair value of awards (per share)	$	11.86

No share options grants were made for the years ended December 31, 2015 and 2016. No SARs grants were made for the years ended December 31, 2015, 2016 and 2017.

The Company used the following assumptions in the BSM pricing model when valuing its Share‑Based Awards:

· Expected volatility. For 2017 grants, the Company used historical volatility of the Company’s own shares.

· Expected term.  The expected term of awards granted has been calculated following the “simplified” method, using half of the sum of the contractual and vesting terms, because the Company has no historical pattern of exercises sufficient to estimate the expected term on a more reliable basis.

· Dividend yield.  This assumption is measured as the average annualized dividend estimated to be paid by the Company over the expected life of the award as a percentage of the share price at the grant date. The Company did not declare any dividends with respect to 2015, 2016 or 2017. Currently, the Company does not have any plans to pay dividends in the near term. Because optionees were generally compensated for dividends and the Company has no plans to pay cash dividends in the near term, it used an expected dividend yield of zero in its option pricing model for awards granted in the year ended December 31, 2017.

· Fair value of ordinary shares.  The Company estimated the fair value of its ordinary shares using the closing price of its ordinary shares on the NASDAQ Global Select Market on the date of grant.

· Risk‑free interest rate.  The Company used the risk-free interest rates based on the US Treasury yield curve in effect at the grant date.

Business Unit Equity Awards

In 2016, the Company finalized the process of restructuring certain of the business units in its E-Commerce, Taxi and Classifieds operating segments (the “Participating Subsidiaries”) into separate legal structures.  In connection with this restructuring, and to align the incentives of the relevant employees with the operations of the Participating Subsidiaries, the Company granted 2.4 million equity incentive awards under the 2016 Plan to the senior employees of these business units in total in 2015-2017, which entitle the participants to receive options to acquire redeemable depositary receipts of shares in the respective operating subsidiaries (Note 14) upon the satisfaction of defined vesting criteria (the “Business Unit Equity Awards”), of which 2.0 million remain outstanding as of December 31, 2017. The exercise price of the Business Unit Equity Awards shall be determined from time to time by the Board and the standard vesting schedule for Business Unit Equity Awards under the 2016 Plan is consistent with Shared Based Awards granted in the Company��s shares. Business Unit Equity Awards and any awards granted to management of the Participating Subsidiaries outside of the 2016 Plan are not to exceed 20% of such Participating Subsidiary’s shares issued and outstanding from time to time.

The Company has recorded share-based compensation expense in respect of such awards in the amount of RUB 192, RUB 260 and RUB 267 ($4.6) for the years ended December 31, 2015, 2016 and 2017, respectively.

Share‑Based Compensation Expense

The Company recognized share‑based compensation expense of RUB 2,718, RUB 3,422 and RUB 4,193 ($72.8) for the years ended December 31, 2015, 2016 and 2017, respectively. The Company recognized RUB 41, RUB 36 and RUB 62  ($1.1) in related tax benefits for the years ended December 31, 2015, 2016 and 2017, respectively.

16. INFORMATION ABOUT SEGMENTS, REVENUES & GEOGRAPHIC AREAS

Starting from 2015, following the changes in the Company’s organizational structure, the Company’s chief operating decision maker (“CODM”) is the management committee including its CEO, COO and a group of COO’s direct reports. The Company reports its financial performance based on the following reportable segments: Search and Portal, E-commerce, Taxi and Classifieds. The results of the Company’s remaining operating segments, including Media Services, Yandex Data Factory, Discovery Services and Search and Portal in Turkey, that do not meet the quantitative or

the qualitative thresholds for disclosure, are combined into the other category defined as Experiments which is shown separately from the reportable segments and reconciling items.

Reportable segments derive revenues from the following services:

· Search and Portal offers a broad range of services in Russia, Belarus, Kazakhstan and, for periods prior to the imposition of sanctions on Yandex by the government of Ukraine in May 2017, all services of the Company offered in Ukraine, among which are search, location-based, personalized and mobile services, that enable the Company’s users to find relevant and objective information quickly and easily and to communicate and connect over the internet, from both their desktops and mobile devices;

· E-commerce — the Company’s Yandex.Market e-commerce gateway service gives retailers an additional platform to reach customers seeking specific retailer, product or price information. Product search on Yandex.Market is designed to deliver the most relevant shopping results to the Company’s users;

· Classifieds derives revenues from online advertising and listing fees;

· Taxi derives revenue from commissions for providing ride-sharing services related to the Company's Yandex.Taxi service and Food delivery business (FoodFox acquired in December 2017). Yandex.Taxi operated in 167 cities with 100,000+ population, and in 56 cities with population of 50,000+ across Russia, Georgia, Armenia, Kazakhstan, Belarus, Moldova and Kyrgyzstan as of December 31, 2017.

The Company accounts for intersegment revenues as if the services were provided to third parties, that is, at the level approximating current market prices.

(1) The Company records revenue net of VAT, sales agency commissions and bonuses and discounts.

17. RELATED‑PARTY TRANSACTIONS

The Company has in place a registration rights agreement with its major shareholders that allows them to require the Company to register Class A shares held by them under the U.S. Securities Act of 1933, as amended (the “Securities Act”), under certain circumstances. In such circumstances, the Company is obliged to pay all expenses, other than underwriting commissions and discounts, relating to any such registration.

Following the sale of the controlling interest to Sberbank and the deconsolidation of Yandex.Money in July 2013, the Company retained a noncontrolling interest and significant influence over Yandex.Money’s business. The Company continues to use Yandex.Money for payment processing and to sublease to Yandex.Money part of its premises. The amount of revenues from subleasing and other services was RUB 91, RUB 106 and RUB 86 ($1.5) for the years ended December 31, 2015, 2016 and 2017, respectively. The amount of fees for online payment commissions was RUB 143, RUB 173 and RUB 439 ($7.6) for the years ended December 31, 2015, 2016 and 2017, respectively. As of December 31, 2016 and 2017, the amount of receivables related to payment processing was RUB 47 and RUB 158 ($2.7), respectively. The Company believes that the terms of the agreements with Yandex.Money are comparable to the terms obtained in arm’s‑length transactions with unrelated similarly situated customers and suppliers of the Company.

In 2016, the Company granted loans to certain senior employees in the amount of RUB 173 ($3.0) (Note 5). The loans bear interest rate is up to 8% per annum and mature in 2019-2022.

18. SUBSEQUENT EVENTS

In February 2018, the Company granted RSUs to purchase an aggregate of up to 2,777,312 Class A shares to its employees pursuant to the 2016 Plan.

In February 2018, the Company settled its liability  in respect of contingent consideration related to the number of qualifying taxi trips following RosTaxi acquisition in January 2015 (Note 4) by 259,560 of its Class A ordinary shares equivalent to RUB 500 ($8.7).

In February and March 2018, the Company designated $80.4 (RUB 4,572 at the exchange rate as of the dates of designation) of deposits with a third party bank as a hedging instrument to hedge its exposure to changes in the fair value of the unrecognized firm commitments on its servers and network equipment arrangements that are attributable to foreign currency risk for the period ending December 31, 2018. The maturities of such deposits are aligned with the purchase payments schedule.

On the February 7, 2018, the Company and Uber International C.V. (“Uber”), a subsidiary of Uber Technologies, Inc., have completed the merger of Yandex.Taxi Holding B.V. and its subsidiaries (“Yandex.Taxi Group”) and several Uber legal entities into a new private limited liability company MLU B.V., incorporated under the laws of the Netherlands. The Company and Uber have each contributed their legal entities operating the ride-sharing and food delivery businesses in Russia, Kazakhstan, Azerbaijan, Armenia, Belarus, Georgia, Kyrgyzstan and Moldova, and $100.0 (RUB 5,722 as of the date of acquisition) and $225.0 (RUB 12,874 as of the date of acquisition) in cash, respectively. The merger was accounted for as a business combination.

As a result of the transaction 63.03% of share capital of the combined entity is held by the Company, 35.93% by Uber and 1.04% by the employees of Yandex.Taxi Group based on the total number of outstanding shares.

Given the recent timing of the transaction and pending completion of the valuations for identifiable net assets acquired and liabilities assumed, at the time these financial statements were authorized for issuance, the initial accounting for the business combination is incomplete. Accordingly, not all relevant disclosures are available for the

business combination. The Company will report the purchase price allocation in condensed consolidated balance sheets as of March 31, 2018.

In February 2018, Uber Technologies, Inc. transferred 1,527,507 of its Class A Common Shares (“Exchange shares”) to the Company in exchange for additional 2.03% in the share capital of MLU B.V.. At the same time, Uber Technologies, Inc. entered into an arrangement with the Company to hold an option to repurchase Exchange shares within the 3-year period since one-year anniversary of deal close, while the Company has an obligation to sell these shares. The Company has the corresponding option to sell Exchange shares within the same period, while Uber Technologies, Inc. has an obligation to purchase these shares.
