As MTS Belarus and MTS Bank are equity investees, our revenues and subscriber data do not include MTS Belarus and MTS Bank.

In 2013, we changed our reporting currency to the Russian Ruble. Previously, we have presented our consolidated financial statements in the U.S. Dollar. The change in the reporting currency is to allow a greater transparency of our financial and operating performance as it more closely reflects the profile of our revenue and operating income, a major portion of which are generated in Russian rubles. In accordance with authoritative guidance, comparative information was restated in Russian rubles.

In this document, references to "U.S. dollars," "dollars," "$" or "USD" are to the lawful currency of the United States, "Russian rubles," "rubles" or "RUB" are to the lawful currency of the Russian Federation, "hryvnias" are to the lawful currency of Ukraine, "soms" are to the lawful currency of Uzbekistan, "manats" are to the lawful currency of Turkmenistan, "dram" are to the lawful currency of Armenia and "€," "euro" or "EUR" are to the lawful currency of the member states of the European Union that adopted a single currency in accordance with the Treaty of Rome establishing the European Economic Community, as amended by the treaty on the European Union, signed at Maastricht on February 7, 1992. References in this document to "shares" or "ordinary shares" refers to our ordinary shares, "ADSs" refers to our American depositary shares, each of which represents two ordinary shares, and "ADRs" refers to the American depositary receipts that evidence our ADSs. Prior to May 3, 2010, each ADS represented five ordinary shares of our common stock. "CIS" refers to the Commonwealth of Independent States.

The following tables show, for the periods indicated, certain information regarding the exchange rate between the ruble and the U.S. dollar, based on data published by the Central Bank of Russia ("CBR"). These rates may differ from the actual rates used in preparation of our financial statements and other financial information provided herein.

The exchange rate between the ruble and the U.S. dollar published by the CBR for April 24, 2014 was 35.66 rubles per U.S. dollar.

Matters discussed in this document may constitute forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933 (the "U.S. Securities Act"), and Section 21E of the U.S. Securities Exchange Act of 1934 (the "U.S. Exchange Act"). The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their businesses. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts.

MTS desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation and other relevant law. This document and any other written or oral statements made by us or on our behalf may include forward-looking statements. We have based these forward- looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. The words "believe," "expect," "anticipate," "intend," "estimate," "forecast," "project," "predict," "plan," "may," "should," "could" and similar expressions identify forward-looking statements. Forward-looking statements appear in a number of places including, without limitation, "Item 3. Key Information—D. Risk Factors," "Item 4. Information on Our Company—B. Business Overview," "Item 5. Operating and Financial Review and Prospects," and "Item 11. Quantitative and Qualitative Disclosures about Market Risk" and include statements regarding:

The forward-looking statements in this document are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management's examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections. In addition to these important factors and matters

discussed elsewhere herein, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include:

All future written and verbal forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. Readers are cautioned not to place undue reliance on these forward-looking statements. Except to the extent required by law, neither we, nor any of our respective agents, employees or advisors intends or has any duty or obligation to supplement, amend, update or revise any of the forward-looking statements contained or incorporated by reference in this document.

The selected consolidated financial data for the years ended December 31, 2011, 2012 and 2013, and as of December 31, 2012 and 2013, are derived from the audited consolidated financial statements, prepared in accordance with U.S. GAAP included elsewhere in this document. The numbers presented in the following table for the years ended December 31, 2009 and 2010 and as of December 31, 2009, 2010 and 2011were derived from our audited consolidated financial statements presented in U.S. dollars and not included in this document and restated in Russian rubles using average monthly exchange rates and period end exchange rates between the U.S. dollars and the Russian rubles based on data published by the CBR, except for data derived from statement of cash flows. Cash flows data for the years ended December 31, 2009 and 2010 were restated in Russian rubles using average annual rates between the U.S. dollar and the Russian ruble based on data published by the CBR. Our results of operations for all periods presented in the following table exclude financial data of Uzdunrobita, our former subsidiary in Uzbekistan. The results of operations of Uzdunrobita are reported as discontinued operations in our audited consolidated financial statements for the years ended December 31, 2011, 2012 and 2013, and as of December 31, 2012 and 2013.

Our results of operations are affected by acquisitions. Results of operations of acquired businesses are included in our audited consolidated financial statements from their respective dates of acquisition, other than with respect to our acquisition of certain subsidiaries of Sistema, as further described below.

In October 2009, we acquired a 50.91% stake in Comstar, a provider of fixed line communication services in Russia, Ukraine and Armenia, from Sistema for RUB 39.15 billion. We subsequently increased our ownership stake in Comstar to 61.97% (or 64.03% excluding treasury shares) in December 2009 and to 70.97% (or 73.33% excluding treasury shares) in September 2010 through a voluntary tender offer. On December 23, 2010, the extraordinary general meetings of shareholders of Comstar and MTS approved a merger of Comstar and us. On March 10, 2011, we completed a share buyback as part of the reorganization of MTS and on April 1, 2011 the merger was completed. A total of 8,000 MTS ordinary shares representing 0.0004% of our issued share capital were repurchased in the buyback for RUB 1.96 million. The buyback price was set at RUB 245.19 per one MTS ordinary share. In addition, a total of 22,483,791 Comstar ordinary shares representing 5.38% of the Comstar issued share capital were repurchased for RUB 4.8 billion. The buyback price was set at RUB 212.85 per one Comstar ordinary share. The remaining 98,853,996 Comstar ordinary shares were converted into MTS ordinary shares at an exchange ratio of 0.825 MTS ordinary shares for each Comstar ordinary share. See "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Acquisitions."

In June 2010, we acquired a 15% ownership interest in TS-Retail OJSC ("TS-Retail") from Sistema for RUB 31 consequently increasing our effective ownership interest in TS-Retail to 49.6%. We subsequently increased our effective ownership interest in TS-Retail to 50.95%, which was achieved through a voluntary tender offer to purchase Comstar's shares in September 2010.

In August 2010, we acquired a 95% ownership interest in Metro-Telecom, a company which owns a fiber optic network located in the Moscow metro, from Invest-Svyaz CJSC, a wholly owned subsidiary of Sistema, for RUB 339.35 million.

In December 2010, we acquired a 100% ownership stake in Sistema Telecom, a subsidiary of Sistema which owns the egg-shaped logos each of the telecommunications companies operating within the Sistema group uses, including us, and a 45% ownership stake in TS-Retail, from Sistema for RUB 11.59 billion. As a result of this acquisition and the completion of our merger with Comstar on April 1, 2011, we currently own a 100% stake in TS-Retail.

As we, Comstar, TS-Retail, Sistema Telecom and Metro-Telecom were under the common control of Sistema, our acquisition of majority stakes in these companies has been treated as a combination of entities under common control and accounted for in a manner similar to a pooling-of-interests, i.e., the assets and liabilities acquired were recorded at their historical carrying value and the consolidated financial statements were retroactively restated to reflect the Group as if these companies had been owned since the beginning of the earliest period presented. Accordingly, the financial data presented below for the year ended December 31, 2009, the financial year preceding the acquisitions, have been restated to include the financial position and results of operations of the companies acquired from Sistema as if the acquisitions had occurred as of January 1, 2009, and the financial data for the years ended December 31, 2009 and 2010 includes the financial position and results of operations of Comstar, TS-Retail, Sistema Telecom and Metro-Telecom for the full-year.

The selected financial data should be read in conjunction with our audited consolidated financial statements, included elsewhere in this document, "Item 3. Key Information—D. Risk Factors" and "Item 5. Operating and Financial Review and Prospects." Certain industry and operating data are also provided below. The numbers presented in the following table for the years ended December 31, 2009 and 2010 and as of December 31, 2009, 2010 and 2011were derived from our audited consolidated financial statements presented in U.S. dollars and not included in this document and restated into Russian rubles using average monthly exchange rates and period end exchange rates between the U.S. dollar and the Russian ruble based on data published by the CBR, except for data derived from statement of cash flows. Cash flows data for the years ended December 31, 2009 and 2010 were restated in Russian rubles using average annual rates between the U.S. dollar and the Russian ruble based on data published by the CBR:

(4): Includes notes payable, bank loans, capital lease obligations and other debt.
(5): Calculated as book value of total debt divided by the sum of the book values of total shareholders' equity and total debt at the end of the relevant period. See footnote 4 above for the definition of "total debt."
(6): Source: AC&M-Consulting and our data. Operating data is presented for mobile operations only. None of this data is derived from our audited consolidated financial statements.
(7): We define a subscriber as an individual or organization whose account shows chargeable activity within 61 days (or 183 days in the case of Prepaid tariffs) or whose account does not have a negative balance for more than this period.
(8): Average monthly minutes of usage per subscriber is calculated by dividing the total number of minutes of usage during a given period by the average number of our subscribers during the period and dividing by the number of months in that period.
(9): We calculate average monthly service revenue per subscriber by dividing our service revenues for a given period, including interconnect, guest roaming fees and connection fees, by the average number of our subscribers during that period and dividing by the number of months in that period.
(10): In Ukraine, subscriber acquisition costs are calculated as total sales and marketing expenses, handset subsidies and cost of sim cards and vouchers for a given period divided by the total number of gross subscribers added during that period. In Russia, it is impracticable to calculate subscriber acquisition costs for the period as we now have the mobile and fixed line parts of the business combined in one reportable segment, "Russia."
(11): We define our churn as the total number of subscribers who cease to be a subscriber (see footnote 7 above for the definition of a "subscriber") during the period (whether involuntarily due to non-payment or voluntarily, at such subscriber's request), expressed as a percentage of the average number of our subscribers during that period.

An investment in our securities involves a certain degree of risk. in our securities involves a certain degree of risk. You should carefully consider the following information about these risks, together with other information contained in this document, before you decide to buy our securities. If any of the following risks actually occur, our business, prospects, financial condition or results of operations coul be materially adversely affected. In that case, the value of our securities could also decline and you could lose all or part of your investment. In addition, please read "Cautionary Statement Regarding Forward-Looking Statements" where we describe additional uncertainties associated with our business and the forward-looking statements included in this document.

Emerging markets such as the Russian Federation, Ukraine and other CIS countries are subject to greater risks than more developed markets, including significant legal, economic, tax and political risks.

Investors in emerging markets such as the Russian Federation, Armenia, Ukraine, Turkmenistan, Kyrgyzstan, Uzbekistan and other CIS countries should be aware that these markets are subject to greater risk than more developed markets, including in some cases, significant legal, economic, tax and political risks. Investors should also note that emerging economies such as the economies of the Russian Federation and Ukraine are subject to rapid change and that the information set out herein may become outdated relatively quickly.

Global financial or economic crises or even financial turmoil in any large emerging market country tend to adversely affect prices in equity markets of most or all emerging market countries as investors move their money to more stable, developed markets. Beginning in the second half of 2008, the Russian equity markets have been highly volatile, principally due to the impact of the global financial and economic crisis on the Russian economy as well as the current crisis in Ukraine. Such volatility has caused market regulators to temporarily suspend trading on the Moscow Interbank Currency Exchange ("MICEX") and the Russian Trading System ("RTS") multiple times. MICEX and RTS stock market indices have experienced significant overall declines since their peaks in May 2008, including an over ten percent fall during the first three months of 2014 in response to the current crisis in Ukraine and deepening concerns over the strength of the Russian economy. As has happened in the past, financial problems or an increase in the perceived risks associated with investing in emerging economies due to, inter alia, geopolitical disputes such as the current crisis in Ukraine, could dampen foreign investment in Russia and adversely affect the Russian economy. In addition, during such times, businesses that operate in emerging markets can face severe liquidity constraints as funding sources are withdrawn. Furthermore, in doing business in various countries of the CIS, we face risks similar to (and sometimes greater than) those that we face in Russia and Ukraine. For example, see "—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations." Accordingly, investors should exercise particular care in evaluating the risks involved and must decide for themselves whether, in light of those risks, their investment is appropriate. Generally, investment in emerging markets is suitable for sophisticated investors who fully appreciate the significance of the risks involved and investors are urged to consult with their own legal and financial advisors before making an investment in our securities.

The telecommunications services market is characterized by rapid technological change, which could render our services obsolete or non-competitive and result in the loss of our market share and a decrease in our revenues.

The telecommunications industry is subject to rapid and significant changes in technology and is characterized by the continuous introduction of new products and services. The mobile telecommunications industry in Russia is also experiencing significant technological change, as evidenced by the introduction in recent years of new standards for radio telecommunications, such as Wi-Fi, Worldwide Inter-operability for Microwave Access ("Wi-Max"), Enhanced Data Rates for Global Evolution ("EDGE"), Universal Mobile Telecommunications System ("UMTS"), and Long Term Evolution ("LTE"), as well as ongoing improvements in the capacity and quality of communications, shorter development cycles for new products and enhancements and changes in customer requirements and preferences. Such continuing technological advances make it difficult to predict the extent of the future competition we may face and it is possible that existing, proposed or as yet undeveloped technologies will become dominant in the future and render the technologies we use less profitable or even obsolete. New products and services that are more commercially effective than our products and services may also be developed. Furthermore, we may not be successful in responding in a timely and cost-effective way to keep up with these developments. Changing our products or services in response to market demand may require the adoption of new technologies that could render many of the technologies that we are currently implementing less competitive or obsolete. To respond successfully to technological advances and emerging industry standards, we may require substantial capital expenditures and access to related or enabling technologies in order to integrate the new technology with our existing technology.

We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies.

The wireless telecommunications services markets in which we operate are highly competitive, particularly in Russia and Ukraine, where mobile penetration exceeds 100%. We also face increased competition in our cable TV and fixed line business, where the market for alternative fixed line communications services in Russia is rapidly evolving and becoming increasingly competitive. Competition is generally based on price, product functionality, range of service offerings and customer service.

Our principal wireless competitors in Russia are Open Joint Stock Company "Vimpel Communications," or "Vimpelcom", and Open Joint Stock Company MegaFon ("MegaFon"). We also face competition from several regional operators and Tele2 Russia which is undergoing a reorganization (as described further below) that may lead to the creation of the fourth federal operator in the course of 2015.

In addition, on April 1, 2011, the Russian government completed the reorganization of state-controlled telecommunications companies Svyazinvest Telecommunications Investment Joint Stock Company ("Svyazinvest"), and Open Joint Stock Company Long-Distance and International Telecommunications Rostelecom ("Rostelecom"). As a result, Rostelecom is currently the largest fixed-line operator and fourth largest mobile operator in Russia.

In October 2010, Sistema and Svyazinvest entered into an exchange transaction, upon completion of which, Svyazinvest obtained control over 100% of the share capital in Sky Link, Sistema acquired the 23.33% stake in MGTS controlled by Svyazinvest and Comstar transferred 25% plus 1 share in Svyazinvest to Rostelecom for cash consideration of 26 billion rubles. Sky Link is a Moscow-based code division multiple access ("CDMA") operator holding GSM licenses for a majority of Russian regions. In July 2012, Rostelecom acquired 100% of Sky Link which at the time of this acquisition held licenses in 76 Russian regions covering more than 90% of the total Russian population. In addition, Rostelecom won tenders for 39 out of 40 licenses to provide fourth-generation ("4G") wireless services within the 2.3-2.4 GHz frequency band and in November 2011 received permission from the Ministry of Defense to use the allotted frequencies for the creation of a 4G network.

On April 4, 2013, the Federal Antimonopoly Service approved a transaction for Airport Alliance, a member of VTB Group, to acquire 100% of Tele2 Russia, which was later completed. Subsequently, VTB Bank sold 50% of Tele2 Russia to a consortium of private investors, including affiliates of Bank "Rossiya", whose main shareholder is Mr. Yury Kovalchuk, and also entities linked to Mr. Alexey Mordashov. Both of these individuals are reputedly among Russia's most successful and influential businessmen. On December, 30, 2013 shareholders of Rostelecom approved a reorganization plan which led to the spin-out of its mobile business into RT-Mobile Ltd. It is reported that RT-Mobile Ltd's business has been contributed as capital for a new joint venture concluded between Rostelecom and Tele2 Russia, under the name of "T2 Rus Holding". During the first stage of integration, seven subsidiaries of Rostelecom will become part of T2 Rus Holding, while under the second stage Rostelecom will contribute 100% of RT-Mobile into the joint venture's equity capital and consequently will acquire a 45% share in it. The second stage of the transaction is planned to be completed by the end of 2014. In 2014, T2 Rus Holding will be reorganized into T2 RTK Holding and is scheduled to start operations under the Tele2 brand in more than 60 regions of Russia. Therefore T2 RTK Holding may become one of the key players in the mobile telecommunications market in Russia, which may materially adversely affect our business, financial condition and results of operations.

According to Direct INFO, Rostelecom controls over 75% of all fixed line telecommunications services in Russia. The emergence of Rostelecom as an integrated nationwide provider of fixed line local and long distance communications services as well as its reorganized business holdings in mobile communications services may significantly increase competition in our markets. In particular, a new

mobile operator involving this state-controlled group may receive favorable pricing terms to interconnect from the regional fixed line operators within its group, putting us at a competitive disadvantage. See also "—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues."

Of the telecommunication services we provide, broadband Internet access is among the most competitive. While the Moscow and St. Petersburg markets have become mature in recent years (more than 70% of the market is controlled by the five largest companies), regional markets are the fastest growing markets, and it is expected that regional markets will follow the same trend as the Moscow and St. Petersburg markets in the coming years, with competition in such markets becoming extremely intense. If we fail to obtain and maintain a substantial share of the broadband Internet access market, our business, financial condition, results of operations or prospects or the value of the ADSs may be materially adversely affected.

In addition, we believe that Rostelecom, as a state-controlled company, is currently able to influence telecommunications policy and regulation in Russia and may cause substantial increases in interconnect rates for access to fixed line operators' networks by mobile cellular operators. Similarly, Rostelecom may cause substantial decreases in interconnect rates for access to mobile cellular operators' networks by fixed line operators, which could cause our revenues to decrease and may materially adversely affect our business, financial condition and results of operations.

Competition in the Ukrainian wireless telecommunications market has significantly intensified over the last several years and may further intensify as a result of the current political crisis. See "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations," and "—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

In October 2010, the Antimonopoly Committee of Ukraine (the "AMC"), approved the merger of Kyivstar, our primary mobile competitor in Ukraine, with URS and Golden Telecom Ukraine, a Ukrainian mobile operator controlled by Vimpelcom, in connection with Vimpelcom's restructuring. On September 4, 2013, Golden Telecom ceased to provide mobile telecommunication services in Ukraine, and its subscribers were invited to re-connect to Kyivstar. It is not clear how the Vimpelcom restructuring in Ukraine will affect our operations. Aggressive pricing by our competitors in Ukraine, driven primarily by Astelit, has driven down the price per minute levels in recent years for mobile communication, which in conjunction with the economic crisis in Ukraine has contributed to the slowdown in the growth rate of the Ukrainian wireless telecommunications market. Presently, the controlled rise of prices, monetization of services, the customer experience of our services and value for money are the most important drivers for the competitive situation in Ukraine. However, we may face additional competition from other European telecommunication companies in the future in the event that Ukraine enters into cooperation agreements with or accedes into the European Union and is required to liberalize access to its telecoms markets for other European operators. These factors may adversely affect our own business, financial condition and results of operations.

The competitive situation for our services in Ukraine may also be influenced by the expected introduction of a mobile number portability ("MNP") service from July 1, 2014 (however due to technical delays by the company responsible for administrating the ported numbers data base, the MNP launch is likely to be postponed until the end of 2014), and also by the sale by the SKM company of Trimob (the only operator in Ukraine with a UMTS license). Similar provisions regarding MNP are already in force in Russia, see also "—Legal Risks and Uncertainties—Regulatory changes in Russia,

including the reduction of settlement rate, the mobile number portability principle and others may have a material adverse effect on our financial condition and results of operations."

In Belarus, we face increasing competition and aggressive pricing from Best CJSC, a subsidiary of System Capital Management and Turkcell Iletisim Hizmetleri A.S. ("Turkcell") operating in Belarus under the "life:)" brand. Additionally, in 2011, the government of Belarus announced its intention to hold a public tender to privatize a 51% ownership interest in MTS Belarus with an opening price of $1.0 billion (RUB 29.4 billion). The public tender was scheduled to be held on December 23, 2011, but was cancelled due to a lack of bidders, and is now expected to be held by the State Property Committee of Belarus in 2014 with subsequent reduction in price. The terms of share disposal have not yet been determined, although it may be conducted either through a public tender or by entering into a direct contract with a particular purchaser. If we are unable to acquire this ownership interest at a commercially reasonable price, or if it is acquired by one of our competitors, it may impact our competitive position and results of operations in Belarus.

We also face competition in Armenia. In 2009, France Telecom operating under the Orange brand entered the Armenian telecommunications market and began offering voice and data transmission services, as well as mobile phones at highly competitive prices. By the end of 2013, Orange had a market share of 16.6% and continued to pursue its strategy of providing telecommunication services (voice and internet) at highly competitive prices.

Following the resumption of our operations in Turkmenistan we continue to face price competition from our main competitor Altyn Asyr on international roaming rates and also capacity restrictions that impact on the development of our third-generation "3G" mobile data network in Turkmenistan. MTS-Turkmenistan is required to route both international traffic signals as well as domestic traffic signals entirely through the telecommunications network infrastructure of the state owned telecom operator Turkmentelekom. However, in spite of our further requests for additional network capacity in accordance with our interconnection agreements with Turkmentelekom, there has not been a corresponding increase in capacity made available to us to accommodate the volume of MTS-Turkmenistan's traffic signals. In addition, Turkmentelekom may also refuse to lease communication lines needed for the day-to-day operation of MTS-Turkmenistan's 3G network. As a result, the data service of MTS-Turkmenistan could become less attractive for the subscribers, which could adversely affect the results of our operations in Turkmenistan.

Generally, increased levels of competition, including from the potential entry of new mobile operators, government-backed operators, mobile virtual network operators and alternative fixed line operators in the markets where we operate, as well as the strengthening of existing operators and increased use of Internet protocol telephony, may adversely affect our ability to increase the number of subscribers. This in turn could result in reduced operating margins and a loss of market share, as well as necessitating different pricing, service or marketing policies, which may have a material adverse effect on our business, financial condition and results of our operations.

We are subject to anti-corruption laws in the jurisdictions in which we operate, including anti-corruption laws of Russia and the US Foreign Corrupt Practices Act (the "FCPA"), and we may be subject to the UK Bribery Act of 2010 (the "UK Bribery Act"). Our failure to comply therewith could result in penalties which could harm our reputation and have a material adverse effect on our business, financial condition and results of operations.

We are subject to the FCPA, which generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business and/or other benefits, along with various other anti-corruption laws. We may also be subject to the UK Bribery Act. The UK Bribery Act is broader in scope than the FCPA in that it directly addresses commercial

bribery in addition to bribery of government officials and it does not recognize certain exceptions, notably facilitation payments that are permitted by the FCPA.

Although we regularly review and update our policies and procedures designed to ensure that we, our employees, distributors and other intermediaries comply with the anti-corruption laws to which we are subject, there is no assurance that such policies or procedures will work effectively all of the time or protect us against liability under these or other laws for actions taken by our employees, distributors and other intermediaries with respect to our business or any businesses that we may acquire. We operate primarily in Russia and other countries of the former Soviet Union, many of which pose elevated risks of corruption violations. We and certain of our subsidiaries are in frequent contact with persons who may be considered "foreign officials" under the FCPA and UK Bribery Act, and therefore, are subject to an increased risk of potential FCPA and UK Bribery Act violations. If we are not in compliance with the FCPA, the UK Bribery Act and other laws governing the conduct of business with government entities (including local laws), we may be subject to criminal and civil penalties and other remedial measures, which could have an adverse impact on our business, results of operations, financial condition and liquidity.

As previously disclosed, in March 2014, we received requests for the provision of information from the United States Securities and Exchange Commission and the United States Department of Justice relating to an investigation of the Group's former subsidiary in Uzbekistan. See also Note 4 to our audited consolidated financial statements. As the aforementioned US government investigations are at an early stage, we cannot predict the outcome of the investigations, including any fines or penalties that may be imposed, and such fines or penalties could be significant. Any investigation of any potential violations of the FCPA, the UK Bribery Act or other anti-corruption laws by US, UK or foreign authorities could have an adverse impact on our business, financial condition and results of operations.

Our controlling shareholder has the ability to take actions that may conflict with the interests of other holders of our securities.

We are controlled by Sistema, which owns 51.46% of our total charter capital (53.47% excluding treasury shares). If not otherwise required by Russian law and/or our charter, resolutions at a shareholders' meeting are adopted by a simple majority in a meeting at which shareholders holding more than half of the issued share capital are present or represented. Accordingly, Sistema has the power to control the outcome of most matters to be decided by vote at a shareholders' meeting and, as long as it holds, either directly or indirectly, a majority of our shares, Sistema will control the appointment of a majority of directors and removal of all directors. Sistema is also able to control or significantly influence the outcome of any vote on matters which require three-quarters majority vote of a shareholders' meeting, such as amendments to the charter, proposed reorganizations substantial asset sales, and other major corporate transactions, among other things. Thus, Sistema can take actions that may conflict with the interests of other security holders. In addition, under certain circumstances, a disposition by Sistema of its controlling stake in our company could harm our business. See also "—Risks Relating to Our Financial Condition—If a change in control occurs, our noteholders and other debt holders may require us to redeem notes or other debt, which could have a material adverse effect on our financial condition and results of operations."

Sistema has a significant amount of outstanding debt. As of December 31, 2013, Sistema had consolidated indebtedness of approximately $41 million (RUB 1,342 million) of short-term debt, $2.47 billion (RUB 80,841 million) comprising the short-term portion of its long-term debt, and $10.8 billion (RUB 353 billion) of long-term debt (net of the short-term portion). At the corporate level, Sistema had $8.99 million (RUB 291 million) of short-term debt, $574.5 million (RUB 18,803 million) comprising the short-term portion of its long-term debt, and $991.1 million (RUB 32,438 million) of long-term debt (net of the short-term portion). Therefore, Sistema will require

significant funds to meet its obligations, which may come in part from dividends paid by its subsidiaries, including us.

Sistema voted in favor of declaring dividends of RUB 39,405 million in 2009 for 2008, RUB 30,697 million in 2010 for 2009, RUB 30,046 million in 2011 for 2010, RUB 30,397 million in 2012 for 2011 and RUB 40,956 million in 2013 for 2012 and half-year 2013. Annual dividends are calculated at the exchange rate on the date when dividends are declared at the Annual General Meeting of Shareholders. The indentures relating to our outstanding notes and other debt do not restrict our ability to pay dividends. As a result of paying dividends, our reliance on external sources of financing may increase, our credit rating may decrease, and our cash flow and ability to repay our debt obligations, or make capital expenditures, investments and acquisitions could be materially adversely affected. Furthermore, our credit ratings can be and have been affected in the past by Sistema's activity and credit ratings.

Failure to effectively implement our geographic expansion strategy as well as difficulties with operational management of the acquired businesses could hamper our continued growth and profitability.

Our continued growth depends, in part, on our ability to identify attractive opportunities in markets that will grow and on our ability to manage the operations of acquired or newly established businesses. Our strategy contemplates the acquisition of additional operations within the CIS in both the mobile and fixed broadband segments. These acquisitions may occur in countries that represent new operating environments for us and, in many instances, may be located a great distance from our corporate headquarters in Russia. We therefore may have less control over their activities. We may also face uncertainties with respect to the operational and financial needs of these businesses, and may, in the course of our acquisitions, incur additional debt to finance the acquisitions and/or take on substantial existing debt of the acquired companies. In addition, we anticipate that the countries into which we may expand will be emerging markets and, as with countries of our current presence, subject to greater political, economic, social and legal risks than more developed markets.

For example, see "—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations."

Our failure to identify attractive opportunities for expansion into new markets and to manage the operations of acquired or newly established businesses in these markets could hamper our continued growth and profitability, and have a material adverse effect on our financial condition, results of operations and prospects.

We have expanded our business through several acquisitions. As part of our growth strategy, we will continue to evaluate opportunities to acquire, invest in or merge with other existing operators or license holders in the CIS and in growing markets outside the CIS, as well as other complementary businesses.

Prior to 2009, most of our acquisitions were of regional operators with a focus on expanding our network and subscriber footprint. In 2011 and 2012, our acquisitions focus shifted to acquiring a minority stake in a subsidiary company of Multiregion JSC and other regional cable TV and broadband providers in furtherance of our strategy to become a provider of integrated telecommunications services. In 2010, we also acquired Sistema Telecom in order to obtain full control over our logos.

These and other business combinations entail a number of risks that could materially and adversely affect our business, financial condition, results of operations and prospects, including the following:

In 2009, for example, we had write downs of $349.4 million (RUB 11,084 million) related to Comstar's investment in Svyazinvest, the government-controlled holding for fixed line telephone companies, which contributed to our loss in the fourth quarter of 2009.

In addition, companies that we acquire may not have internal policies, including accounting policies and internal control procedures that are compatible, compliant or easily integrated with ours.

If any of our future business combinations is structured as a merger with another company, or we merge with or absorb a company subsequent to its acquisition by us, such a merger would be considered a corporate reorganization under Russian law. In turn, this would provide our creditors with a statutory-based right to file a claim seeking to accelerate their claims or terminate the respective obligations, as well as seek damages. To prevail, the creditors would need to prove in court that we will not perform our obligations in due course and the amount of damages suffered. Secured creditors would be required to further prove that the security provided by us, our shareholders or third parties is not sufficient to secure our obligations. Creditors whose claims are secured by pledges do not have the right to claim additional security.

In addition, in April 2013 we acquired a 25.095% stake in OJSC MTS Bank followed by a profit-sharing agreement whereby we and MTS Bank would realize 70% and 30% of the proceeds from the MTS Dengi (MTS Money) project respectively. The MTS Dengi project launched by us and MTS Bank is aimed at providing customers throughout Russia with payment tools, including credit cards, near-field communications-enabled SIM cards and PoS (point-of-sale) credit. If the risks associated with participating in the banking sector lead to our inability to receive the expected profits from MTS Dengi project it could have an adverse effect on our financial statements, financial condition and results of operations.

We may also be involved in various litigation to protect our title or other rights related to acquired businesses and incur some unpredicted loss. For example, in December 2005, we acquired a 51% stake in Tarino Limited from Nomihold Securities Inc. for $150.0 million (RUB 4,322 million) in cash and entered into a put and call option agreement for the remaining 49% interest for a price of $170 million

(RUB 4,898 million) as we believed, that at that time it was the indirect owner of Bitel, a Kyrgyz company holding GSM 900/1800 license for the entire territory of Kyrgyzstan. In the same year, following a decision of the Kyrgyz Supreme Court, Bitel's offices were seized by a third party and we lost operational control over Bitel. In 2007, Nomihold Securities Inc. exercised the put option for the remaining stake in Bitel. During 2005-2013 we wrote down more than $320 million (RUB 8,798 million) relating to the loss of Bitel and other litigation with Nomihold Securities Inc. During the same period we also had other litigation in various jurisdictions to defend our rights relating to Bitel and its assets. In June 2013, an agreement was reached between Nomihold and other associated parties to settle all the claims arising in relation to Bitel and its assets, pursuant to which all proceedings between all the parties involved in such litigation were discontinued and waived and we received a total payment in cash in the amount of $150 million (RUB 4,909 million). The settlement also fully discharged all our outstanding obligations to Nomihold Securities Inc. As a result of the settlement, we released a provision relating to the exercise the put option for acquisition of the remaining stake in Bitel plus damages, interest and other cost that have been provided for in relation to the dispute with Nomihold. See also Note 27 to our audited consolidated financial statements. In addition, a merger, as well as any corporate reorganization and any business combination that constitutes a "major transaction" under Russian law, would trigger the right of our shareholders who abstain from voting on or vote against such reorganization or transaction to sell, and our obligation to buy, their shares in an amount representing up to 10% of our net assets as calculated under Russian Accounting Standards. See "—Legal Risks and Uncertainties—Shareholder rights provisions under Russian law could impose additional obligations and costs on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

If our purchase of Ukrainian Mobile Communications ("UMC") is found to have violated Ukrainian law or the purchase is unwound, our business, financial condition, results of operations and prospects would be materially adversely affected.

On June 7, 2004, the General Prosecutor of Ukraine filed a claim against us and others in the Kiev Commercial Court seeking to unwind the sale made to us by Joint Stock Company Ukrtelecom ("Ukrtelecom") of its 51% stake in UMC. The complaint also sought an order prohibiting us from disposing of our 51% stake in UMC until the claim was resolved on the merits. The claim was based on a provision of the Ukrainian privatization law that included Ukrtelecom among a list of "strategic" state holdings prohibited from alienating or encumbering its assets during the course of its privatization. Although the Cabinet of Ministers of Ukraine had issued a decree in May 2001 specifically authorizing the sale by Ukrtelecom of its entire stake in UMC, the General Prosecutor asserted that the decree contradicted the privatization law and that the sale by Ukrtelecom was therefore illegal and should be unwound. On August 12, 2004, the Kiev Commercial Court rejected the General Prosecutor's claim.

On August 26, 2004, the General Prosecutor's Office requested the Constitutional Court of Ukraine to review whether certain provisions of the Ukrainian privatization law limiting the alienation of assets by privatized companies were applicable to the sale by Ukrtelecom of UMC shares to us. On January 13, 2005, the Constitutional Court of Ukraine refused to initiate the constitutional proceedings arising from the request of the General Prosecutor's Office on the grounds that the request was incompatible with the requirements of Ukrainian constitutional law, and that the issue as it was raised in the request, did not fall within the jurisdiction of the Constitutional Court of Ukraine. The Constitutional Court of Ukraine's decision does not prevent other persons having the right to apply to the Constitutional Court of Ukraine from challenging the constitutionality of provisions of the Ukrainian privatization law applicable to the sale by Ukrtelecom of the UMC shares, and also does not preclude the future challenge of such sale in the commercial courts of Ukraine.

If the Constitutional Court of Ukraine rules that the provisions of the Ukrainian privatization legislation applicable to Ukrtelecom's sale of its stake in UMC are unconstitutional, the Kiev Commercial Court could be requested by the General Prosecutor to re-open the case based on new circumstances and could potentially include additional persons that were not parties to the original proceeding and/or admit additional claims.

In addition, as UMC was formed at a time when Ukraine's legislative framework was developing in an uncertain legal environment, its formation and capital structure may also be subject to challenges. In the event that our purchase of UMC is found to have violated Ukrainian law or the purchase is subject to repeated challenge, or unwound, in whole or in part, our business, financial condition, results of operations and prospects would be materially adversely affected.

If we cannot successfully develop our network, we will be unable to expand our subscriber base and maintain our profitability.

Our ability to increase our subscriber base depends upon the success of our network expansion. We have expended considerable amounts of resources to enable both organic expansion and expansion through acquisitions and plan to continue to do so. Limited information regarding the markets into which we have or are considering expanding, either through acquisitions or new licenses, complicates accurate forecasts of future revenues from those regions, increasing the risk that we may overestimate these revenues. In addition, we may not be able to integrate previous or future acquisitions successfully or operate them profitably. Any difficulties encountered in the transition and integration process and in the operation of acquired companies could have a material adverse effect on our results of operations.

The build-out of our network is also subject to risks and uncertainties, which could delay the introduction of services in some areas and increase the cost of network construction, including difficulty in obtaining base station sites on commercially attractive terms. In addition, telecommunications equipment used in Russia, Ukraine and other CIS countries is subject to governmental certification, and periodic renewals of the same. We are also required to receive permits for the operation of telecommunications equipment as well as governmental certification and/or permission for the import and export of certain network equipment, which can result in procurement delays and slow network development. The failure of any equipment we use to receive timely certification or re-certification could hinder our expansion plans.

For example, the import and export of products containing cryptographic hardware is subject to special documentation requirements and approvals. As telecommunication networks comprise various components with cryptographic hardware, we must comply with these requirements in order to import such components. Moreover, where imported equipment does not contain cryptographic hardware, the federal customs service requires manufacturers to provide written confirmation regarding the absence of such hardware. The range of goods requiring the provision of "certificates of conformance" by suppliers and manufactures prior to their import into Russia has also been expanded to cover most of our key network components, and imported radioelectronic equipment is required to be licensed by the Russian Ministry of Industry and Trade. Similar requirements regarding the import and export of cryptographic hardware exist in Ukraine.

Furthermore, as a result of the downturn in the global financial markets, certain banks have curtailed their lending programs, which may limit our ability to obtain external financing and, in turn, result in the reduction of our capital expenditure program. To the extent we fail to expand our network on a timely basis, we could experience difficulty in expanding our subscriber base. See also "—Risks Relating to Our Financial Condition—If we are unable to obtain adequate capital, we may have to limit our operations substantially, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

Our inability to develop additional sources of revenue could have a material adverse effect on our business, financial condition, results of operations and prospects.

Mobile penetration in Russia and Ukraine reached 170.0% and 133.1%, respectively, as of December, 31, 2013, according to AC&M-Consulting. Until recently, customer growth has been the principal source of revenue growth. Currently, however, increasing competition, market saturation and technological development lead to the increased importance of data services in the Russian market and, to a lesser extent, the markets of other CIS countries. As a result, data services became the key driver of our revenue growth and, therefore, we will need to continue to develop new competitive services, including value-added, 3G, LTE, and others, as well as consider vertical integration opportunities through the development or acquisition of dealers in order to provide us with sources of revenue in addition to standard voice services. Our inability to develop additional sources of revenue could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our failure to further develop and sustain our distribution network as well as the reduction, consolidation or acquisition of independent dealers may lead to a decrease in our subscriber growth rate, market share and revenues.

Following the restructuring of the Euroset Group, the largest mobile handset retailer and leading dealer for major mobile network operators in Russia, as a result of which MegaFon and Vimpelcom acquired equal shares of 50%, we have been working on developing our proprietary distribution network, have signed an additional agreement with Svyaznoy and have been working to increase our relationship with small regional dealers. If we are not successful in expanding and sustaining our proprietary network and maintaining and further developing our distribution network of national, regional and local retailers, our subscriber growth rate, market share and revenues may decrease, which would have a material adverse effect on our business, financial condition, results of operations and prospects. In addition, our ability to attract new customers through Euroset outlets is limited. If competitors continue to expand their footprint in Russia through the acquisition of Svyaznoy's operations, our opportunities for marketing our services through its outlets may be restricted. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Sales and Marketing—Sales and Distribution."

If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues.

Our ability to provide commercially viable services depends on our ability to continue to interconnect cost-effectively with zonal, intercity and international fixed line and mobile operators in Russia, Ukraine and other countries in which we operate. Fees for interconnecting are established by agreements with network operators and vary depending on the network used, the nature of the call and the call destination.

In Ukraine, the government completed the privatization of Ukrtelecom, which, according to its public disclosure, has a 71% share of the local telephony market and an 83% share of the domestic and international long distance market in Ukraine. The auction to privatize Ukrtelecom was held by the State Property Fund of Ukraine in December 2010. On March 11, 2011, following the completion of an independent appraisal required by Ukrainian law, the State Property Fund of Ukraine and ESU LLC, a wholly owned subsidiary of European Privatization & Investment Corporation ("EPIC"), signed an agreement for the sale of a 92.8% stake in Ukrtelecom to ESU LLC. On May 11, 2011, the ownership stake was transferred to ESU LLC upon the payment of a purchase price amounting to 10,575.1 million hryvnia (RUB 36,979.8 million as of May 11, 2011) and the fulfillment of certain requirements under Ukrainian law. It is currently unclear how the privatizations of Ukrtelecom will affect our interconnect arrangements and costs, but there is a chance that our ability to interconnect cost-effectively with other telecommunications operators could be hampered.

Although Russian legislation requires that operators of public switched telephone networks that are deemed to be "substantial position" operators who cannot refuse to provide interconnects or discriminate against one operator over another, we believe that in practice, some operators attempt to impede wireless operators by delaying interconnect applications and establishing technical conditions for interconnecting that can be met only by certain operators.

Any difficulties or delays in interconnecting cost-effectively with other networks could hinder our ability to provide services at competitive prices or at all, causing us to lose market share and revenues, which would have a material adverse effect on our business and results of operations. See also "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

In addition, as part of the restructuring of Svyazinvest, the Russian government has expressed its intent to establish a fourth national mobile operator in Russia. As Svyazinvest controls regional fixed line operators in all regions of Russia (other than Moscow), a mobile operator established as part of the Svyazinvest group may receive preferential terms for interconnecting with these operators, which would allow it greater flexibility in setting tariffs and put us at a competitive disadvantage. See also "—We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies."

Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations.

On June 24, 2010, MTS Ukraine and its competitors, including Kyivstar, Golden Telecom Ukraine, URS, Ukrtelecom, Astelit, Intertelecom and PEOPLENet, were declared by the AMC to have a dominant position on the network interconnect market. As a result, the interconnect fees charged by us and our competitors for terminating calls connecting to any of our respective networks became subject to regulation by the National Commission for the Regulation on Communications (the "NCRC"), which since November 23, 2011 has been succeeded by the National Commission for the State Regulation of Communications and Informatization (the "NCCIR"). See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Competition" for additional information.

In 2011, the NCRC announced its intent to change the telecommunications regulations in Ukraine to regulate the interconnect rates of only those operators deemed by the AMC to have "significant market power." Kyivstar and MTS Ukraine are the largest mobile cellular operators in Ukraine with market shares of 43% and 37%, as of December 31, 2013, respectively, according to AC&M-Consulting.

In December 2011, the Telecommunications Law was amended to introduce the term "significant market power operator on traffic termination market" (SMP). An operator qualifies as a SMP in a particular market if its share of gross revenue from the provision of traffic transfer services on fixed or mobile telecommunications networks during the last 12 months exceeded 25% of total gross revenues of all telecommunications operators for the same services during the same period. Thus, on October 20, 2011, the NCRC recognized all telecommunications operators on the Ukrainian market as SMPs in the market of call termination on their respective networks.

On September 22 2011, the NCRC proposed a draft law on regulating SMP operators which called for, among other things, non-discriminatory access to their infrastructure for the wholesale market and for regulating the retail market. Under the proposed law, the NCRC may place an obligation on SMP operators to separate the accounting of revenues and costs for different services, to calculate the cost of their services according to NCRC rules and to price the services in accordance with NCRC's rules. The draft law was not adopted and as of January 31, 2014 is being amended. The NCCIR has assumed the NCRC's powers to consider interconnect rates and may reduce the interconnect rates that we

charge, which, in turn, may have a material adverse effect on our financial condition and results of operations.

In June 2012, the definition of SMP was changed by an amendment to the Telecommunications Law which came into effect on January 8, 2013. From this date qualification as a SMP has been assessed with reference to the market as defined by NCCIR (and not only by reference to the traffic termination market). Criteria i.e. the SMP market share remained the same as in previous version of the Telecommunications Law. See also "—Legal Risks and Uncertainties—Changes in Ukrainian telecommunications legislation have caused uncertainty in relation to the regulation of the Ukrainian telecommunications industry and may adversely affect our business, financial condition and results of operations."

We may not realize the benefits we expect to receive from our investments in 3G and 4G wireless services, which could have a material adverse effect on our business and results of operations.

In May 2007, the Federal Service for Supervision in the Area of Communications and Mass Media awarded MegaFon, Vimpelcom and us a license to provide 3G services in the Russian Federation. In July 2012 these three companies and Rostelecom were awarded licenses to provide 4G services. The 3G license allows us to provide mobile radio telephone services using the International Mobile Telecommunications-2000 ("IMT-2000/UMTS") standard. The 4G license allows us to provide services using the LTE standard. 4G wireless services are expected to provide faster, higher quality data transfer and streaming capabilities as compared to 2G and 3G and may pose additional competition for 3G providers. Historically, mobile operators that have developed 3G and 4G networks have experienced various difficulties and challenges, including a limited supply of compatible handsets, limited international roaming capabilities, as well as 3G and 4G software and network-related problems. We may experience similar problems or encounter new difficulties when developing our 3G and 4G networks and may be unable to fully resolve them. For example, we cannot be certain that:

See also "—If we cannot successfully develop our network, we will be unable to expand our subscriber base and maintain our profitability."

In addition, Russian military authorities also use frequencies in the 3G and 4G spectrum, which may limit the availability of 3G and 4G frequencies for commercial use in certain areas. During the construction of our 3G and 4G network, there is also a risk that the frequencies assigned to us for commercial use may overlap with frequencies used by the Russian military. For example, conflicts over

the availability of frequency reserved for military use in Moscow caused delay in the commercial launch of 3G services in Moscow by all 3G license holders, although some of these frequencies were cleared for commercial use in 2009. If additional overlap were to occur, it could cause problems or delays in the development and operation of our 3G and 4G network in Russia.

We may also face competition from operators using second generation ("2G") or other forms of 3G technology. For example, licenses for the use of CDMA technology have already been granted for the provision of fixed wireless services in a number of regions throughout Russia. CDMA is a 2G digital cellular telephony technology that can be used for the provision of both wireless and fixed services. If CDMA operators were able to develop widespread networks throughout Russia, we would face increased competition.

Potential competition from other 3G, CDMA and 4G providers, together with any substantial problem with the rollout of our 3G and 4G network and provision of 3G and 4G services in the future, could materially adversely affect our business, financial condition and results of operations.

In December 2013, the State Commission for Radio frequencies introduced several modifications to the conditions of using the frequency band for 3G and 4G. These modifications included the principle of technological neutrality for frequency bands 900 MHz (UMTS) and 1800 MHz (LTE), but also imposed additional obligations for network operators. Pursuant to these modifications, 3G and 4G operators will now be able to use bands in the frequency range as supplementary frequencies for GSM, UMTS and LTE coverage. However, in the event that we receive new bandwidth allocation, and also as a result of the renewal of the current decisions of State Commission for Radio Frequencies, we are obliged to provide network coverage to settlements with lower subscriber numbers, where the commercial rationale for doing so may otherwise be limited. Such changes lead to additional costs for the construction of our 3G and 4G wireless network and consequently may adversely affect our business, financial condition and results of operations.

If we are unable to successfully develop and/or deploy 4G wireless services in the countries in which we operate or one of the operators in the market obtains significant technological and/or commercial advantage over us in 4G wireless services, it may have a material adverse effect on our business and results of operations in the long term.

The next step in the development of telecommunications in the countries where we operate is the deployment of 4G/LTE networks. The cost of 4G/LTE network development and quality of services (data speed, quality of coverage) depends on the band and the width of frequency range given to an operator.

In September 2011, the Russian government announced its intention to auction frequencies for LTE use on a national level in 2012. Additionally, outside of the auction process, the State Radio Frequencies Commission granted Scartel (operating the Yota retail brand) a paired range of LTE frequencies (2x30 MHz), in the 2.5-2.7 GHz band for use on the whole territory of Russia in exchange for 4G frequencies held by Scartel for Wi-Max technology with a total width of 70MHz. Four sets of frequencies in the 791-862 MHz band were planned to be sold during the auction in 2012, after which the winners of the frequencies would receive frequencies in the 2.5-2.7 GHz band. The remaining frequencies 40 MHz of the 2.5-2.7 GHz band were allocated evenly during the tender among four major market participants (us, Vimpelcom, MegaFon and Rostelecom).

Initially it was planned that all operators would receive equal access to the Scartel infrastructure, which would allow each operator to reduce its 4G/LTE network development costs. In March 2011, we, MegaFon, Vimpelcom and Rostelecom signed a non-binding memorandum of understanding with Scartel, according to which we, MegaFon, Vimpelcom and Rostelecom were to receive access to Scartel's 4G network infrastructure (which was yet to be built) and were to receive options to purchase

shares in Scartel in 2014 at a price determined by an independent appraisal. MTS considered a preliminary value assessment of Scartel to be unduly high.

In July 2012, Alisher Usmanov and Scartel shareholders (Telconet Capital and Rostechnologyi) formed a telecommunications holding company, Garsdale. In exchange for an 82% interest in Garsdale, AF Telecom, which is controlled by Alisher Usmanov, contributed 50% of Megafon's shares into Garsdale's share capital. Rostechnologyi and Telconet Capital, which held 25.1% and 74.9% stakes in Scartel, respectively, contributed 100% of Scartel into Garsdale's share capital, in return for which they received an 18% stake in Garsdale, which was split equally between Rostechnologyi and Telconet Capital. On 12 July 2012, the Federal Service for Supervision in the Area of Communications and Mass Media awarded each of MegaFon, Vimpelcom, Rostelecom and us a license to provide 4G services using LTE and its subsequent modifications in the frequency range of 791-862 MHz.

On October 1, 2013, MegaFon acquired Maxiten Co Limited, which in turn owned 100% of the shares in Scartel and Yota Ltd. from Garsdale. The transaction was approved by the general shareholders meeting of MegaFon and by the Federal Antimonopoly Service ("FAS"). At present, MegaFon holds 4G/LTE network through Scartel as well as controlling the continuous spectrum of frequencies 2 x 40 MHz in the band of LTE FDD 2600 MHz. As a result of this transaction, MegaFon obtained a competitive advantage in terms of LTE network development costs and may also obtain an advantage in LTE network performance. For example, in February, 2014, MegaFon launched LTE Advanced network in Moscow using LTE FDD 2600 MHz band and announced plans of further roll-out of its LTE Advanced network in the 15 largest cities in Russia. In addition, MegaFon will have an opportunity to consolidate financial and operational indicators of Scartel/Yota which will increase its formal market share in the mobile communications market.

According to the decision of State Commission for Radio Frequencies as of March, 16, 2012 all telecommunication operators excluding MegaFon and Rostelecom are not permitted to get LTE frequencies in the Krasnodarsky Region until the end of 2016. On April 11, 2013, we filed an application with the State Commission for Radio Frequencies to amend this decision and requested a postponement of the introduction of such restrictions until the end of 2014; however, the consideration of our application was postponed for the duration of the Olympic Games. Currently we are appealing a case against actions and inactions of State Commission for Radio Frequencies in the Arbitrazh Court of Moscow. The next court session is scheduled for June 3, 2014 as well as the next meeting of the State Commission for Radio Frequencies. Our inability to develop an LTE network in the Krasnodarsky Region until 2016 may have an adverse effect on our business, financial condition and results of operations.

On September 18, 2013, the mobile operator Altyn Asyr, our major competitor in Turkmenistan, brought into operation a 4G network using LTE technology. At the moment MTS-Turkmenistan does not have a 4G-license which may lead to the loss of revenues from its data service which could have a material adverse effect on the results of our operations.

Furthermore, the limited number of available frequencies may prevent us from realizing the full benefits we expect to receive from the development of a 4G network, because our network capacity would be constrained and our ability to expand limited. Moreover, if we cannot develop a commercially viable 4G network, and one of our competitors does, that competitor would have an advantage over us, which in turn may have a material adverse effect on our business.

Our inability to obtain a UMTS license in Ukraine on commercially reasonable terms, or at all, may negatively affect our competitive position in Ukraine.

In September 2009, the NCRC announced plans to launch a tender for a single 3G/UMTS mobile services license in Ukraine with the starting price set at 400 million hryvnia (equivalent to RUB 1,515.1 million at December 31, 2009). However, the NCRC canceled the planned tender in November

2009 following a decision by the President of Ukraine to put the tender and conversion of the radio frequencies on hold. Following the election of Viktor Yanukovich as Ukraine's President in February 2010, a tender for a 3G/UMTS license in Ukraine was expected in 2012 after the planned sale of Trimob, (formerly known as Utel), a subsidiary of Ukrtelecom, which is the only UMTS license holder in Ukraine. Trimob was expected to be sold by the end of 2012, subject to approval by the AMC and certain other regulatory bodies, but to date there have been no announcements regarding the progress of the sale of Trimob. A sale of Trimob to one of our competitors would provide that competitor with a significant advantage over us and would adversely affect our competitiveness in Ukraine, as well as our business, financial condition and results of operations.

The Ukrainian government has previously indicated that funds required for the conversion of the remaining UMTS frequencies have not been provided in Ukraine's 2013 State Budget. Therefore, there is a possibility of additional UMTS frequency spectrum being made available in 2014 as a means of generating revenue to tackle the problem with the state budget deficit. Nevertheless, if we do not acquire Trimob and we are unable to acquire a UMTS license when an auction is ultimately held, and our competitors do, those competitors would have an advantage over us.

Our ability to win a competitive tender for a 3G/UMTS license in Ukraine may require us to pay a significant amount for the license as well as incur significant costs in building out the 3G network, and we may not be able to recoup these costs through our service revenues. The listed potential price for one license is around 1 bln hryvnias. If we do not obtain a 3G/UMTS license, the award of the license to one of our competitors would increase the competition we face in the provision of both GSM and 3G services in Ukraine and inhibit our expansion efforts. Either of the foregoing may have a material adverse effect on our business, financial condition, results of operations and prospects.

Service disruptions on our networks could lead to a loss of subscribers, damage to our reputation, violations of the terms of our licenses and subscriber contracts and penalties.

We are able to deliver services only to the extent that we can protect our network systems against damage from communications failures, computer viruses, power failures, natural disasters and unauthorized access. Any system failure, accident or security breach that causes interruptions in our operations could impair our ability to provide services to our customers and materially adversely affect our business and results of operations. In addition, to the extent that any disruption or security breach results in a loss of or damage to customers' data or applications, or inappropriate disclosure of confidential information, we may incur liability as a result, including costs to remedy the damage caused by these disruptions or security breaches.

While we maintain back-up systems for our telecommunications equipment, network management, operations and maintenance systems, these systems may not ensure recovery in the event of a network failure. In particular, in the event of extensive software and/or hardware failures, significant disruptions to our systems could occur, leading to our inability to provide services. The quality of our services in roaming (including roaming between networks) also depends inter alia on the network quality of our roaming partners which is out of our control. Disruptions in our provision of services could lead to a loss of subscribers, damage to our reputation, violations of the terms of our licenses and subscriber contracts and penalties.

Our computer and communications hardware is protected through physical and software safeguards. However, it is still vulnerable to fire, storm, flood, loss of power, telecommunications failures, interconnect failures, physical or software break-ins, viruses and similar events. Although our computer and communications hardware is insured against fires, storms and floods, we do not carry business interruption insurance to protect us in the event of a catastrophe, even though such an event could have a material adverse effect on our business.

Failure to fulfill the terms of our licenses could result in their suspension or termination, which could have a material adverse effect on our business and results of operations.

Each of our mobile licenses requires service to be offered by a specific date and some contain further requirements as to network capacity and territorial coverage to be reached by specified dates. In addition, all of our mobile licenses require us to comply with various telecommunications regulations relating to the use of radio frequencies and numbering capacity allocated to us, network construction, interconnect rules and technical requirements relating to compliance with law enforcement authorities' requests, among others. The license requirements applicable to our fixed line businesses include participation in a federal communications network, adherence to technical standards, investment in network infrastructure, employment of Russian technical personnel and the provision of certain services to the federal government and PSTN subscribers at regulated tariffs, among others. If we fail to comply with the requirements of Russian, Ukrainian or other applicable legislation or we fail to meet any terms of our licenses, our licenses and other authorizations necessary for our operations may be suspended or terminated which could significantly limit our operations. In addition to the impact on our operations, the suspension or loss of certain licenses could also cause an event of default under certain of our debt obligations and certain of our debt to be accelerated. A suspension or termination of our licenses or other necessary governmental authorizations could therefore have a material adverse effect on our business and results of operations.

Failure to renew our licenses or receive renewed or new licenses with similar terms to our existing licenses could have a material adverse effect on our business and results of operations.

Our telecommunications licenses expire in various years from 2014 to 2022. These licenses may be renewed upon application to the relevant governmental authorities. Government officials in Russia and the other CIS countries in which we operate consider the compliance with license requirements as well as the conditions of using the allocated frequency range when deciding whether to renew a license. License renewals may be subject to additional conditions, such as payment obligations or the mandatory modernization of our network.

In addition, we may be subject to penalties or our licenses may be suspended or terminated for non-compliance with the new license requirements. The suspension or loss of certain licenses could significantly limit our operations and cause certain of our debt to be accelerated.

The current license to construct and maintain the telecommunication network and provide services with them was granted to MTS Ukraine on July 20, 2010 and terminated on December 3, 2013. On October 15, 2013, the NCCIR refused to renew the current license and recommended that MTS Ukraine receive a new license to provide operations in telecommunications sphere. Receiving a new license involves additional costs in comparison with the renewal of the current one and MTS Ukraine filed a lawsuit against NCCIR seeking to declare the failure to renew the license as unlawful. On November 19, 2013, the claims of MTS Ukraine were satisfied and the license term was renewed until January 2019.

Failure to renew our telecommunications licenses or receive renewed or new licenses with similar terms to existing licenses could significantly limit our operations, which could have a material adverse effect on our business and results of operations.

Until recently, telecommunications operators carried out activities and received licenses in Crimea in compliance with Ukrainian legislation. However, following the referendum in Crimea on March 16, 2014 in favor of joining the Russian Federation and consequent developments in the region to date, various countries recognize Crimean secession whereas others do not, therefore, our licensing status in Crimea, as well as the ability to receive continuous cash flow is subject to uncertainty. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations," and

"—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

If frequencies currently assigned to us are reassigned to other users or if we fail to obtain renewals of our frequency allocations, our network capacity will be constrained and our ability to expand limited, resulting in a loss of market share and lower revenues.

There is a limited number of frequencies available for wireless operators in each of the regions in which we operate or hold licenses to operate. We are dependent on access to adequate spectrum allocation in each market in which we operate in order to maintain and expand our subscriber base. If frequencies are not allocated to us in the future in the required quantities, as well as with the geographic span and for time periods that would allow us to provide wireless services on a commercially feasible basis throughout all of our license areas, our business, financial condition, results of operations and prospects may be materially adversely affected.

A loss of allocated spectrum, which is not replaced by other adequate allocations, could also have a substantial adverse impact on our network capacity. In addition, frequency allocations are often issued for periods that are shorter than the terms of the licenses, and such allocations may not be renewed in a timely manner or at all. If our frequencies are revoked or we are unable to renew our frequency allocations, our network capacity would be constrained and our ability to expand limited, resulting in a loss of market share and lower revenues.

An increase in the fees for frequency spectrum usage could have a negative effect on our financial results.

The terms of our licenses in Russia and the CIS require that we make payments for frequency spectrum usage. Any significant increase in the fees payable for the frequency channels that we use or additional frequency channels that we need in Russia or the CIS could have a negative effect on our financial results.

In late 2012, Russian network operators accepted that from 2014 the fees for frequency spectrum usage would be calculated based on the total frequency band allocated to each operator in each region with such frequency spectrum usage determined with reference to the decision of State Commission for Radio Frequencies, frequency allocation decisions or to the license conditions. It is expected that fees will increase up to 10% pursuant to the new approach. The application of the new fees is expected in the first half of 2014.

Similarly, in April 2010, the Cabinet of Ministers of Ukraine significantly increased the fees for frequency spectrum usage in Ukraine for cellular communications. Furthermore, according to the Tax Code of Ukraine, the fees payable for frequency usage shall be determined based in part on the rate of inflation and reviewed annually effective January 1, 2011. Accordingly, the fees for frequency usage were increased by 8.9% in 2012 as compared to 2011, by 8% in 2013 as compared to 2012, and are doubled from April 1, 2014 as compared to 2013.

If we are unable to maintain our favorable brand image, we may be unable to attract new subscribers and retain existing subscribers, leading to loss of market share and revenues.

Developing and maintaining awareness of our brands is critical to informing and educating the public about our current and future services and is an important element in attracting new subscribers. We believe that the importance of brand recognition is increasing as our markets become more competitive. Successful promotion of our brands will depend largely on the effectiveness of our marketing efforts and on our ability to provide reliable and useful products and services at competitive prices. Brand promotion activities may not yield increased operating revenues, and even if they do, such operating revenues may not offset the operating expenses we incur in building our brands.

Furthermore, our ability to attract new subscribers and retain existing subscribers depends, in part, on our ability to maintain what we believe to be our favorable brand image. Negative publicity or rumors regarding our company, our shareholders and affiliates or our services could negatively affect this brand image, which could lead to loss of market share and revenues. Our failure to successfully and efficiently promote and maintain our brands may limit our ability to attract new subscribers and retain our existing subscribers and materially adversely affect our business and results of operations.

We engage in transactions with related parties, which may present conflicts of interest, potentially resulting in the conclusion of transactions on terms not determined by market forces.

We have purchased interests in various telecommunications companies from Sistema and entered into arrangements with subsidiaries and affiliates of Sistema for the provision of advertising services (Open Joint Stock Company Advertising Agency Maxima ("Maxima"), IT services and hardware purchases (LLC Sitronics IT, Closed Joint Stock Company Sitronics Telecom Solutions, LLC Sitronics Smart Technologies and NVision Group), banking services (MTS Bank, formerly Moscow Bank of Reconstruction and Development ("MBRD")), telecommunication services (LLC Stream), medical services (Closed Joint Stock Company Medsi Group), the purchase of a new billing system (Open Joint Stock Company Sitronics), maintenance of the residential and commercial real estate (Closed Joint Stock Company City-Telecom). Related party transactions with Sistema and other companies within the Sistema group may present conflicts of interest, potentially resulting in the conclusion of transactions on terms not determined by market forces. See "Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions."

In the event that our minority shareholders or the minority shareholders of our subsidiaries were to successfully challenge past or future interested party transactions, or do not approve interested party transactions or other matters in the future, we could be limited in our operational flexibility and our business, financial condition, results of operations and prospects could be materially adversely affected.

We own less than 100% of the equity interests in some of our subsidiaries. In addition, certain of our wholly owned subsidiaries have had other shareholders in the past. We and our subsidiaries in the past have carried out, and continue to carry out, transactions that may be considered to be "interested party transactions" under Russian law, requiring approval by disinterested directors, disinterested independent directors or disinterested shareholders depending on the nature of the transaction and parties involved. The provisions of Russian law defining which transactions must be approved as "interested party transactions" are subject to different interpretations and, as a result, it is possible that our and our subsidiaries' interpretation and application of these provisions could be subject to challenge. Any such challenges, if successful, could result in the invalidation of transactions, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, Russian law requires a three-quarters majority vote of the holders of voting stock present at a shareholders' meeting to approve certain transactions and other matters, including, for example, charter amendments, major transactions involving assets in excess of 50% of the assets of the company, repurchase of shares by the company and certain share issuances. In some cases, minority shareholders may not approve interested party transactions requiring their approval or other matters requiring minority shareholder or supermajority approval. In the event that these minority shareholders were to successfully challenge past interested party transactions, or do not approve interested party transactions or other matters in the future, we could be limited in our operational flexibility and our business, financial condition, results of operations and prospects could be materially adversely affected.

Our competitive position and future prospects depend on our senior managers and other key personnel and our inability to attract, retain and motivate qualified key personnel could have a material adverse effect on our business, financial condition and results of operations.

Our ability to maintain our competitive position and to implement our business strategy is dependent to a large degree on the services of our senior management team and other key personnel. Moreover, competition in Russia and in the other countries where we operate for personnel with relevant expertise is intense due to the relatively small number of qualified individuals. As a result, we attempt to structure our compensation packages in a manner consistent with the evolving standards of the labor markets in these countries. We are not insured against the detrimental effects to our business resulting from the loss or dismissal of our key personnel. In addition, it is not common practice in Russia and the other countries where we operate to purchase key-man insurance policies, and we do not carry such policies for our senior management and other key personnel. The loss or decline in services of members of our senior management team or an inability to attract, retain and motivate qualified key personnel could have a material adverse effect on our business, financial condition and results of operations.

The entry of mobile virtual network operators into the Russian mobile communications market could increase competition and subscriber churn, resulting in a loss of our market share and decreased revenue.

On December 29, 2008, the Ministry of Communications and Mass Media adopted an order establishing the requirements for mobile virtual network operators ("MVNOs"). MVNOs are companies that provide mobile communications services but do not own the radio frequencies and, often, the network infrastructure required to do so. According to the order, MVNOs in Russia must be licensed, and their use of frequencies and infrastructure and rendering of services will be done pursuant to agreements entered into between MVNOs and existing frequency holders. There is no requirement that existing frequency holders transact with the MVNOs, and agreements between them will be entered into at their option.

The aim of the Ministry in establishing the legal framework for MVNOs to operate is to increase competition in the Russian mobile services market, which is currently dominated by us, Vimpelcom and MegaFon. While existing frequency holders, including us, may receive revenues from MVNOs for the use of our frequencies and network infrastructure, we expect these revenues to be lower than the revenues we would receive if providing services directly to subscribers. In addition, in the event we lose subscribers to MVNOs that lease their frequencies and infrastructure from an operator other than us, we will be deprived of the revenue streams from both the subscribers and the MVNOs. The MVNOs may also establish aggressive tariffs, which could result in increased subscriber churn and/or driving down the tariffs of all mobile operators.

In December 2011, Scartel reached an agreement with MegaFon and Rostelecom to allow them to provide LTE services through Scartel's network in exchange for permitting Scartel to use the two companies' network infrastructure. In February 2012, Scartel and MegaFon received the necessary licenses to allow MegaFon to provide such services over the Scartel LTE network.

In February 2014, the Russian Government approved a "Development of competition in telecommunications" roadmap, which provides for the preparation of a report on realization of the MVNO business model. This report is expected to be presented to the Government in the second quarter of 2014.

While the impact of MVNOs' entry into the Russian mobile communications market as well as the way of MVNO development in Russia (including 4G network) is not yet clear, the emergence of any of the foregoing trends could increase market competition and subscriber churn and, as a result, have a material adverse effect on our business, financial condition, results of operations and prospects.

A finding by FAS that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operation.

Our businesses have grown substantially through the acquisition and formation of companies, many of which required the prior approval of, or subsequent notification to, FAS or its predecessor agencies. In part, relevant legislation in certain cases restricts the acquisition or formation of companies by groups of companies or individuals acting in concert without such prior approval or notification. While we believe that we have complied with the applicable legislation for our acquisitions and formation of new companies, this legislation is sometimes vague and subject to varying interpretations. If FAS were to conclude that our acquisition or formation of a new company was done in contravention of applicable legislation, it could impose administrative sanctions and require the divestiture of such company or other assets, which could have a material adverse effect on our business, financial condition and results of operations.

In October 2010, FAS found that we, Vimpelcom and MegaFon violated antimonopoly laws on competition relating to our pricing for roaming services. As a result, FAS imposed an administrative fine on us in the amount of RUB 21.9 million which represents 1.0% of the revenues we derived from roaming services in CIS countries in 2009. We paid the fine imposed on us by FAS on March 28, 2011.

In addition, in October 2011, FAS began an investigation of our and Vimpelcom's actions, suspecting violation of antimonopoly laws by coordinated pricing of iPhone 4 handsets. On April 26, 2012 we and Vimpelcom were found to be in violation of the Competition law through coordinating prices from September 2010 through April 2011; however, FAS also noted that these violations were voluntarily rectified, and terminated the proceedings as a result. On July 17, 2012, FAS imposed a turnover-based fine of RUB 16.9 million on us, which we complied with.

In November 2012, FAS began an investigation of the contractual relationship between operators and content providers and in December 2012 issued a warning to us and Vimpelcom requesting each of us to cease the violation of antimonopoly laws, particularly relating, to solicitation of services to the subscribers. We and Vimpelcom complied with the requirements and on February 7, 2013, FAS closed the case.

In October 2013, the FAS regional office in the Pskov Region began an investigation in relation to an alleged violation by us, Vimpelcom and Megafon of antimonopoly law by coordinating pricing of the mobile data services on the territory of Pskov Region. The investigation was terminated in December 2013 due to the absence of breach of antimonopoly law of mobile operators.

If FAS finds our actions insufficient to rectify past violations or antimonopoly laws or issues new warnings and requests in the future, inter alia, in other regions, this could have a material adverse effect on our business, financial condition, results of operations and prospects.

A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations.

In December 2011, the AMC opened an investigation into whether MTS Ukraine violated antimonopoly legislation with its pricing of international roaming services. The AMC stated that the average price of international roaming services offered by MTS Ukraine and its roaming partners was higher than the corresponding prices in the European Union, which might demonstrate that the prices charged by MTS Ukraine were not economically justified. The investigation aimed to examine whether MTS Ukraine used its dominant position in the Ukrainian telecommunications market to establish prices that would not be possible if there was significant competition on the telecommunications market. Although we believe that we did not violate antimonopoly laws, we could be liable for up to 10% of MTS Ukraine revenues. In December, 2012 the AMC issued obligatory recommendations to MTS Ukraine and Kyivstar to lower the prices both for international roaming services and national

mobile services. In December 2012 MTS Ukraine submitted a report discussing the implementation of these recommendations and in January 2013, both claims of AMC were dismissed and no penalties were imposed on us. However, the AMC may determine that we violated antimonopoly legislation in this or other matters (for example, through increasing prices for mobile services at a faster pace than the consumer price growth rate), and may impose fines on us, which may have a material adverse effect on our business, financial condition and results of operation. In addition, we may be required to adjust the prices that we charge for international roaming services, which may adversely affect our revenues. See also "—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations" and "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Competition" for additional information.

If we are found to have a dominant position in the markets where we operate, the government may regulate our subscriber tariffs and restrict our operations.

Under Russian legislation, FAS may categorize a company controlling between 35%-50% or over 50% of a market or otherwise able to control market conditions as a dominant force in such market. Moreover, recent amendments to Russian antimonopoly regulations made it possible that any three companies collectively holding a market share of over 50% or five companies collectively holding a market share of over 70%, and in each case over 8% individually, can be found to have a dominant position on a certain market. However, in some cases a company could be categorized as dominant even if its share of the corresponding market is less that 35%. Companies controlling over 35% or otherwise occupying a dominant position on the market are listed by FAS in a special register and may become subject to monitoring and reporting requirements with respect to such markets. Current Russian legislation does not clearly define "market" in terms of the types of services or the geographic area. One of our subsidiaries, MGTS, is categorized by the Federal Tariff Service as a natural monopoly in the Moscow telecommunications market. As a result, MGTS' tariffs are subject to regulation by the Federal Tariff Service. Another of our subsidiaries, Comstar-regions, operating in Khanty-Mansiysk Autonomous District among others, is categorized as a natural monopoly in the public telecommunications market. See "—MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services."

We were also categorized by FAS as a company with a market share exceeding 35% in the mobile communications market in the Ivanovo Region, Kurgan Region, Magadan Region, Sakhalin Region, Nenets Autonomous District and Udmurt Republic. In the event that we are found in the future to have a dominant position on these or any additional markets, FAS would have the right to impose certain restrictions provided for under the antimonopoly laws, including a mandated reduction in our tariffs, and FAS would have the right to impose certain restrictions on our operations in such markets. See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation—Competition, Interconnect and Pricing" for additional information.

In case we are found to have dominant position we can be subject to penalties and turn-over based fine may be imposed on us in relation to certain violations of antimonopoly law. The level of fine is from 1% to 15% of revenue on the market where the violation was conducted, with 8% being the base level of the fine.

Additionally, MTS Ukraine, was categorized as a company with a dominant position in the telecommunications market and is subject to certain government imposed restrictions, including limitations on the interconnect rates it can charge other operators. See "—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations" and "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Competition" for additional information.

If we or any of our subsidiaries were to be classified by FAS (or the AMC with respect to our operations in Ukraine) as a dominant market force or as having a dominant position in the market, FAS and the Federal Tariff Service (or the AMC, as the case may be) would have the power to impose certain restrictions on our or their businesses. In particular, the authorities may impose on us tariffs at levels that could be competitively disadvantageous and/or set interconnect rates between operators that may adversely affect our revenues. Moreover, our refusal to adjust our tariffs according to such government-determined rates could result in the imposition of fines. Additionally, geographic restrictions on our expansion could reduce our subscriber base and prevent us from fully implementing our business strategy, which may materially adversely affect our business, financial condition, results of operations and prospects.

If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations.

In addition to the regulation of dominant operators by FAS, the Federal Law on Communications provides for the special regulation of telecommunications operators occupying a "substantial position," i.e., operators which, together with their affiliates, have 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic in a geographically defined zone within the Russian Federation. These regulations provide for governmental regulation of the key terms of such operators' interconnect agreements, including the interconnect tariffs. In addition, such operators are required to develop standard key terms of interconnect agreements and publish them as a public offer made to all operators who intend to interconnect to the networks of those operators. For additional information, see "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation."

At present, the foregoing regulations apply only to fixed line operators in Russia and therefore apply to our fixed line business. Draft legislation was introduced in 2008 that would extend the law to apply to mobile operators. Although the proposed law was not adopted, the risk that similar legislation will be introduced and adopted in the future remains. If legislation which extends the foregoing regulations to apply to mobile operators is adopted, and we and any of our mobile operator subsidiaries operating in Russia are identified as operators occupying a "substantial position," regulators may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our revenues, financial condition and results of operations.

In addition, MGTS is categorized as fixed line operator occupying a substantial position in the Moscow telecommunications market and therefore its interconnect tariffs are subject to state regulation. In January 2013, Comstar-UTS was excluded from the List of "substantial operators" in Moscow and MTS was not included therein. We believe that interconnect tariffs previously approved by the Federal Agency on Communications for Comstar-UTS also apply to MTS following the merger completed on April 1, 2011. There is however a probability that we could be categorized as fixed line operator occupying a substantial position in Moscow due to our affiliation with MGTS and because of our integration with Comstar-UTS. As a result of the state regulation of the relevant interconnection rates, substantial operators may be unable to increase these in line with economic developments or any increases of our relevant costs, resulting in a material adverse effect on our financial condition and results of operations. See also "—MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services."

MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services.

As the PSTN operator in Moscow, MGTS is considered to be a company holding a dominant position as well as a natural monopoly in the Moscow telecommunications market under Russian

antimonopoly regulations. Consequently, the Federal Tariff Service regulates MGTS' tariffs for most services provided to its PSTN subscribers, including installation fees, fees for using customer lines, local call charges (flat-rate, time-based and combined payment systems), monthly subscription fees (for subscribers to the unlimited tariff plan) and local call charges (for subscribers who do not use the unlimited tariff plan). In addition, the Federal Law on Communications also provides for the special regulation of telecommunications operators occupying a "substantial position," i.e., operators which together with their affiliates have, in the Russian Federation generally or in a geographically defined specific numerical zone, 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic. MGTS was added to the register of telecommunications operators occupying a substantial position in 2006. Accordingly, the interconnect tariffs of MGTS are subject to regulation by the Federal Agency on Communications. While we believe the tariffs currently set by the Federal Tariff Service and the Federal Agency on Communications are sufficient to compensate us for the costs of providing these services, future tariffs may increase in parallel with corresponding increases in our costs and/or inflation.

Although MGTS is permitted to petition the Federal Tariff Service for increases in tariffs based on such criteria as inflation, increased costs and the need for network investments, it is possible that future requested increases may not be granted or that the Federal Tariff Service may not adequately take such factors into account in setting tariffs. If the permissible tariffs applicable to MGTS do not compensate MGTS for the cost of providing services, the business and results of operations could be materially adversely affected. See also "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

Changes to the rules and regulations involving roaming charges in Russia may adversely affect our financial condition and results of operations.

The Russian government has stated its intention to monitor the pricing of roaming services and several draft laws have been submitted for consideration to the State Duma, which are intended to change the regulation of so-called "national" (between networks) and "intra-network" (within network) roaming in Russia by introducing a flat national roaming tariff and eliminating intra-network roaming tariffs for incoming calls. It is not clear whether this legislation will be adopted. However, if the new legislation is adopted, we believe that our revenues from the provision of roaming services would decline considerably, which could have a material adverse effect on our financial condition and results of operations. After an investigation by FAS of our and other telecommunications operators activities in this area in 2010, an administrative fine in the amount of RUB 21.9 million was imposed on us due to the violation of antimonopoly laws relating to our pricing for roaming services. See also "—A finding by FAS that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operation."

Compliance with the new regulations on International Mobile Equipment Identity ("IMEI") numbers may present us with technical difficulties and may lead to the expenditure of significant resources.

In Ukraine a draft law is being considered which will enable each mobile communications subscriber to register the user terminal free-of-charge on a database maintained by the operator, chiefly to prevent their unlawful use. Aimed at discouraging theft, the draft law will obligate operators to suspend or block the traffic transmission of the terminal upon the application of subscriber. It is still unclear if and when this regulation will be adopted. A similar draft law was rejected by the Russian State Duma. If this regulation is adopted in the future, we may be required to develop a system to monitor IMEI numbers, and we may need to establish and maintain a database of IMEI numbers, which would necessitate the expenditure of significant technical and financial resources.

The accession of Russia into the World Trade Organization ("WTO") may lead to legislative and other changes which may adversely affect our business, financial condition and results of operation.

On December 16, 2011, Russia signed the accession protocol in order to enter into the WTO which was ratified by Federal Law on July 21, 2012 and became mandatory law in Russia. This may lead to potentially significant changes in Russian legislation including, among others, regulation of foreign investments in Russian companies, competition laws, telecommunications laws, changes in the taxation system and customs regulations in Russia. In addition, the implementation of the WTO rules may lead to the increase of competition on the markets we operate. It is unclear yet if and when these legislative developments may take place. However, if new legislation is implemented in Russia as a result of accession to the WTO and there is an increase in competition, this could have a material adverse effect on our financial condition and results of operations.

We may be required to make significant investments beyond those that are currently planned to preserve our competitive advantage in response to the rapid evolution of fixed network technology (inter alia our subsidiaries, for example MGTS).

MGTS has completed its migration from analogue public switch telephone network to digital technologies. In 2011, MGTS commenced building an access network employing the Gigabit-capable Passive Optical Network ("GPON") technology which would enable MGTS to enlarge the range of services by introducing High definition television ("HDTV"), video monitoring and other interactive services. However, we could encounter certain difficulties in the process of installing fiber-optic equipment in the subscribers' apartments due to the necessity of conducting adjustment works which could result in fractional subscriber churn.

MGTS invested approximately RUB 1.5 billion in 2010, RUB 1.328 billion in 2011, RUB 9.232 billion in 2012 and RUB 13.547 billion in 2013 to upgrade its infrastructure. If MGTS is not able to upgrade its network in a timely manner or if it is required to make significant investments beyond those that are currently planned, our business, financial condition, results of operations and prospects could be materially adversely affected.

We regard our copyrights, trademarks, trade secrets and similar intellectual property, including our rights to certain domain names, as important to our continued success. We rely upon trademark and copyright law, trade secret protection and confidentiality or license agreements with our employees, customers, partners and others to protect our proprietary rights. Nonetheless, intellectual property rights are especially difficult to protect in the markets where we operate. In these markets, the regulatory agencies charged with protecting intellectual property rights are inadequately funded, legislation is underdeveloped, piracy is commonplace and enforcement of court decisions is difficult. For example, in Russia, legislation in the area of copyrights, trademarks and other types of intellectual property was significantly changed in 2008, and Russian courts have limited experience in applying and interpreting the new laws.

A special court for intellectual property began operating in July 2013 as a new body in the system of Arbitrazh court for dealing with cases relating to protection of intellectual property. It is too early to say how it will influence the quality of protection of intellectual property rights in Russia.

In addition, litigation may be necessary to enforce our intellectual property rights, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement. Any such litigation may result in substantial costs and diversion of resources, and, if decided unfavorably to us, could have a material adverse effect on our business and results of operations. We also may incur substantial acquisition or settlement costs where doing so would strengthen or expand our intellectual property rights or limit our exposure to intellectual property claims of third parties.

In August 2012, we received a claim on behalf of MTS LLC (Simferopol, Ukraine) regarding the invalidation of international registrations of our four trademarks within the territory of Ukraine (the word "MTS" written in Russian and English both in color and black and white). The decision of Kiev City Commercial Court dated July 16, 2013, refused all claims of MTS LLC. Subsequently, MTS LLC filed an appeal of the court decision which was ultimately refused by the Kiev Appellate Commercial court on December 2, 2013. Our inability to protect our rights to these trademarks could have a material adverse effect on our business and results of operations.

We are in the process of transferring to a new billing system and optimizing our information technology infrastructure, which could have a material adverse effect on our business and results of operations in the short term.

We have completed implementation of a new billing system in Russia and Belarus. We have also completed the transfer of our individual subscribers in Ukraine to a new billing system and commenced transferring B2B-subscribers to the new system. We may face difficulties and delays in implementing the new billing system in newly acquired companies. In Ukraine it is still necessary for us to run both the old and new billing systems simultaneously during the transition period, creating additional burdens on our technical support staff. We may also experience technical problems with the new billing system during the transition period. In addition, the introduction of new services by our subsidiaries, including pay-TV services, may result in increased complexity and prolong the duration of the upgrade of our billing system. These factors may increase our operational risks and expenses and inconvenience subscribers in the short term. In addition, we are also currently optimizing our information technology infrastructure, which may result in temporary technical disruptions. The failure or breakdown of key components of our infrastructure in the future, including our billing system and its susceptibility to fraud, could have a material adverse effect on our business and results of operations.

If leaks of confidential information, including information relating to our subscribers, occur it may negatively impact our reputation and our brand image and lead to a loss of market share, which could materially adversely affect our business, financial condition, results of operations and prospects.

Although we make efforts to protect confidential information, breaches of security and leaks of confidential information, including information relating to our subscribers, may negatively impact our reputation and our brand image and result in a loss of market share or otherwise have a material adverse effect on our business, financial condition and results of operations. For example, in January 2003, part of our database of subscribers, containing private subscriber information, was illegally copied and stolen. In addition, in May 2003, certain subscriber databases of several operators in the North-West Region, including those of us, MegaFon, Delta Telecom and two other operators, were stolen. In each case, the stolen databases were thereafter available for sale in Russia. Despite the measures taken, we cannot completely exclude the possibility of such incidents in the future. See also "—Legal Risks and Uncertainties—Our failure to comply with new personal data protection laws and with the regulations of state authorities regarding information security in the telecommunications networks in Russia may have a material adverse effect on our business, financial condition and results of operations."

Alleged medical risks of cellular technology may subject us to negative publicity or litigation, decrease our access to base station sites, diminish subscriber usage and hinder access to additional financing.

Electromagnetic emissions from transmitter masts and mobile handsets may harm the health of individuals exposed for long periods of time to these emissions. The actual or perceived health risks of transmitter masts and mobile handsets could materially adversely affect us or our subsidiaries by reducing subscriber growth, reducing usage per subscriber, increasing the number of product liability lawsuits, increasing the difficulty in obtaining or maintaining sites for base stations and/or reducing the

financing available to the wireless communications industry. Each of these potential circumstances may adversely affect our business, financial condition, results of operations and prospects.

Under the draft law on "Defending against negative electromagnetic emissions from base stations of mobile network" which was proposed in Ukraine in December 2013, a mobile phone base station is classified as a potentially hazardous object. The installation of base stations would need to be made taking into account an environmental impact assessment at the expense of operators and a base station's operations could be terminated if a hazardous effect on health was established. If this draft law is adopted in the future it may lead to an increase in the costs of deploying base stations and increase the maintenance costs of MTS Ukraine.

As a result of the credit market crisis (including uncertainties with respect to financial institutions and the global capital markets), decreased prices for major export commodities (including oil and metals) and other macro-economic challenges currently affecting many of the economies in which we operate, our subscribers' disposable incomes and our vendors' cash flows may be adversely impacted. Consequently, subscribers may modify or decrease their usage of our services or fail to pay the outstanding balances on their accounts, and vendors may significantly increase their prices, eliminate vendor financing or reduce their output.

We may also experience increases in accounts receivable and bad debt among corporate subscribers, some of whom may face liquidity problems and potential bankruptcy, as well as the potential bankruptcy of our corporate partners. For example, in 2008, we extended a short-term loan to Closed Joint Stock Company "Beta Link," or Beta Link, mobile handset retailer and MTS dealer, for $28.2 million (RUB 700.9 million). Beta Link subsequently filed for bankruptcy in March 2009, and we believe it is unlikely that we will be able to recover the loan amount or accounts receivable due from Beta Link.

At the end of 2011, inflation in Belarus increased by 108.7% followed by the local currency depreciation which resulted in a decline of purchasing power. At the end of 2012 and 2013, inflation amounted to 21.8% and 16.5%, correspondingly.

In addition, Belarus is undergoing a balance of payments crisis which resulted from large government-mandated lending by local banks, rapid growth of public sector wages and pensions, and loose monetary policy. Furthermore, the three-year cumulative inflation rate for Belarus exceeded 100 percent as of September 30, 2011 and continues to exceed 100 percent, thereby meeting the quantitative requirement under U.S. GAAP for its economy to be considered highly inflationary, and we have accordingly accounted for this in our financial statements. See Note 2 to our audited consolidated financial statements. It is possible that the use of administrative methods by the Belarusian government to regulate the currency and consumer markets may lead to an aggravation of the crisis. As a result, our business, financial condition and results of operations could be materially adversely affected. See also "—Inflation could increase our costs and adversely affect our results of operations."

A decline in subscriber usage, an increase in bad debts, material changes in equipment pricing or financing terms or the potential bankruptcy of our corporate subscribers or partners may have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, a deterioration in macroeconomic conditions could require us to reassess the value of goodwill on certain of our assets, recorded as a difference between the fair value of the assets of business acquired and its purchase price. This goodwill is subject to impairment tests on an ongoing basis. The weakening macroeconomic conditions in the countries in which we operate and/or a

significant difference between the performance of an acquired company and the business case assumed at the time of acquisition could require us to write down the value of the goodwill or portion of such value. Future write downs relating to the value of the goodwill or portion of such value could have a material adverse effect on our financial condition and results of operations.

Continued turmoil in the credit markets could cause our business, financial condition, results of operations and the value of our shares and ADSs to suffer.

Since the summer of 2007, turmoil in the international credit markets, the recession in the United States and several major European economies and the collapse or near collapse of several large banks and financial services companies in the United States and United Kingdom have resulted in increased volatility in the securities markets in the United States and across Europe, including Russia. In addition, many financial market indices in Russia and other emerging markets, as well as developed markets, have declined significantly since the summer of 2008, and continue to be depressed. Continued volatility in the United States, European and/or Russian securities markets stemming from these or other factors may continue to adversely affect the value of our shares and ADSs.

The downturn in the global financial markets has also caused some companies to experience difficulties accessing their cash equivalents, trading investment securities, drawing on revolvers, issuing debt and raising capital generally. A continuation or repetition of this downturn and resulting volatility of the trading price of our shares and ADSs may negatively impact our ability to obtain financing on commercially reasonable terms and could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our inability to generate sufficient cash flow to satisfy our debt service obligations or to refinance debt on commercially reasonable terms, could materially adversely affect our business, financial condition, results of operations and prospects.

We have a substantial amount of outstanding indebtedness, primarily consisting of the obligations we entered into in connection with our notes and bank loans. As of December 31, 2013, our consolidated total debt, including capital lease obligations, was RUB 219,148 million. Our interest expense for the year ended December 31, 2013 was RUB 15,498 million, net of amounts capitalized.

Our ability to service, repay and refinance our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments, we may default under the terms of our indebtedness, and the holders of our indebtedness would be able to accelerate the maturity of such indebtedness, potentially causing cross-defaults under and acceleration of our other indebtedness. Furthermore, as of December 31, 2013, approximately 16.1% of the debt we have incurred is at floating rates of interest linked to indices, such as LIBOR and EURIBOR, and we have hedged the interest rate risk with respect to approximately 73.1% of our floating interest rate debt. As a result, our interest payment costs can increase if such indices rise.

We may not be able to generate sufficient cash flow or access international capital markets or incur additional indebtedness to enable us to service or repay our indebtedness or to fund our other liquidity needs. We may be required to refinance all or a portion of our indebtedness on or before maturity for a number of reasons; for example, the terms of some of our loan agreements may require us to prepay the loan in certain circumstances, such as a deterioration in our credit rating, we are delisted or our retained earnings drop below a certain level. This, in turn, may force us to sell assets, reduce or delay capital expenditures or seek additional capital. Refinancing or additional financing may not be available on commercially reasonable terms or at all, and we may not be able to sell our assets

or, if sold, the proceeds therefrom may not be sufficient to meet our debt service obligations. Our inability to generate sufficient cash flow to satisfy our debt service obligations, or to refinance debt on commercially reasonable terms, would materially adversely affect our business, financial condition, results of operations and prospects. See "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources."

Ruble depreciation and regulatory changes in foreign currency regulation could increase our costs, decrease our cash reserves, or make it more difficult for us to comply with financial ratios and to repay our debts and would affect the value of dividends received by holders of ADSs.

Over the past two decades, the ruble has fluctuated, at times substantially over short periods of time, against the U.S. dollar. In particular, it significantly depreciated against the U.S. dollar in 2008-2009 as a result of the ongoing global financial downturn and in 2014 as well. For example, on December 31, 2008, the official exchange rate published by the Central Bank of Russia ("CBR") was 29.38 rubles per one U.S. dollar, as compared to 24.55 rubles per one U.S. dollar on December 31, 2007. The ruble continued to depreciate against the U.S. dollar reaching 30.37 rubles per one U.S. dollar on December 31, 2012. As of December 31, 2013 the exchange rate was 32.73 rubles per one U.S. dollar whereas on April 15, 2014 it increased to 35.99 rubles per one U.S. dollar.

The ruble has also depreciated against the euro. On December 31, 2012, the official exchange rate was 40.23 rubles per one euro, as compared to 41.67 rubles per one euro on December 31, 2011. As of December, 31, 2013 the exchange rate was 44.97 rubles per one euro whereas on April 15, 2014 it increased to 49.82 rubles per one euro. See also "—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies."

Currently, the Russian foreign currency market is regulated by legislation, which is aimed at liberalization of currency regulation and lowering of administrative barriers. This legislation provides a general framework and a set of rules, within which both the Russian government and the CBR are authorized to propose various regulations, which result in uncertainty for us in carrying out importation of equipment. The CBR from time to time has imposed various currency-trading restrictions in attempts to support the ruble. However, from 2015, the CBR is planning to let the ruble rate to float freely and intervene only by using its available foreign currency reserves in extreme cases only. The stability of the ruble will depend on many political and economic factors. These include the ability of the government to finance the state budget without recourse to monetary emissions, to control the level of interest rates and inflation. Furthermore, changes in foreign currency regulation may affect our ability to fund payments denominated in foreign currency and result in us entering into supplementary agreements with our foreign counterparts.

A significant portion of our capital expenditure and liabilities and borrowings are either denominated in or tightly linked to the U.S. dollar. Conversely, a majority of our revenues are denominated in rubles. As a result, devaluation of the ruble against the U.S. dollar can adversely affect us by increasing our costs in rubles, both in absolute terms and relative to our revenues, and make it more difficult to comply with the financial ratios contained in our various loan agreements or fund cash payments on our indebtedness on time. It also reduces the U.S. dollar value of tax savings arising from tax incentives for capital investment and the depreciation of our property, plant and equipment, since their basis for tax purposes is denominated in rubles at the time of the investment. Increased tax liability would also increase total expenses, which would have an adverse impact on our results.

We also anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by

the depositary and distributed to holders of the ADSs. Accordingly, the value of dividends received by holders of ADSs will be subject to fluctuations in the exchange rate between the ruble and the U.S. dollar. Depreciation of the ruble against the U.S. dollar could therefore materially adversely affect our financial condition, results of operations and prospects and the value of the ADSs. See also "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies.

A significant portion of our expenditures and liabilities, including capital expenditures and borrowings (including our U.S. dollar denominated notes), are either denominated in, or closely linked to, the U.S. dollar and/or euro, while substantially all of our revenues are denominated in local currencies of the countries where we operate. As a result, the devaluation of local currencies against the Russian ruble can adversely affect our revenues reported in Russian rubles and increase our costs in terms of local currencies. At the same time if the Russian ruble and local currencies decline against the U.S. dollar and/or euro and price increases cannot keep pace, we could have difficulty repaying or refinancing our U.S. dollar and/or euro-denominated indebtedness, including our U.S. dollar denominated notes. In addition, local regulatory restrictions on the sale of hard currency in particular CIS countries (for example, Belarus) may delay our ability to purchase equipment and services necessary for network expansion which, in turn, may cause difficulty in expanding our subscriber base in that country. Further, a portion of our cash balances is held in jurisdictions outside Russia, and as a result of exchange controls in those jurisdictions, these cash balances may not always be readily available for our use.

The Ukrainian hryvnia experienced significant volatility over the last quarter of 2008 and in 2009, with the official exchange rate falling from 4.86 hryvnias per one U.S. dollar as of October 1, 2008 to 7.70 hryvnias and 7.97 hryvnias per one U.S. dollar as of December 31, 2008, and 2009, respectively. The official exchange rate stabilized in the last three years and was 7.99 hryvnias per U.S. dollar as of each of December 31, 2011 and 2012. During this period the exchange rate was supported actively by currency interventions of the National Bank. Since then, Ukraine's continued economic crisis combined with political unrest and events in Crimea has led to the weakening of the hryvnia, with it rising from 7.99 hryvnias per U.S. Dollar on December 31, 2013 to a high of 12.39 hryvnias per U.S. dollar on April 15, 2014—reflecting capital outflow in response to international ratings agencies' downgrade of Ukraine's sovereign rating and to the continuing political instability in Ukraine. In February 2014, Standard & Poor's lowered Ukrainian long-term sovereign credit rating to CCC with a negative outlook. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

The Belarusian ruble experienced significant volatility in 2011, with the official exchange rate falling from 3,000 rubles per one U.S. dollar as of January 1, 2011 to 4,970 rubles per one U.S. dollar as of June 1, 2011 and to 8,570 rubles per one U.S. dollar as of December 31, 2012. On May 23, 2011, the National Bank of the Republic of Belarus announced the significant devaluation of the Belarusian ruble against major foreign currencies to stabilize the situation on the foreign currency exchange market. As of April 15, 2014 the official exchange rate of the Belarusian ruble amounted 9,930 Belarusian rubles per one U.S. dollar.

Furthermore, the three-year cumulative inflation rate for Belarus exceeded 100 percent as of September 30, 2011 and continues to exceed 100 percent, thereby meeting the quantitative requirement under U.S. GAAP for its economy to be considered highly inflationary, and we have accordingly accounted for this in our financial statements. The continued devaluation of the Belarusian ruble and

the highly inflationary economy may adversely affect our revenues from this market. See also "—Inflation could increase our costs and adversely affect our results of operations," "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk" and Note 2 to our audited consolidated financial statements.

If we are unable to obtain adequate capital, we may have to limit our operations substantially, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We will need to make significant capital expenditures, particularly in connection with the development, construction and maintenance of, and the purchasing of software for our mobile and fixed line networks. We spent RUB 72,802 million in 2011, RUB 87,783 million in 2012 and RUB 81,575 million in 2013, for the fulfillment of our capital spending plans. In addition, the acquisition of 3G and 4G licenses and frequency allocations and the build-out of our 3G, 4G and broadband Internet networks will require additional capital expenditures. However, future financings and cash flow from our operations may not be sufficient to meet our planned needs in the event of various unanticipated potential developments, including the following:

On March 21, 2014 the United States and European Union announced sanctions applying to a number of Russian and Ukrainian individuals and associated institutions which were considered to have contributed to the situation in Ukraine and Crimea. Sanctions may be extended and our ability to gain external funding may be affected. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

Our indebtedness and the limits imposed by covenants in our debt obligations could limit our ability to obtain additional financing and thereby constrain our ability to invest in our business and place us at a possible competitive disadvantage. Also, currently we are not able to raise equity financing through newly issued depositary receipts such as ADSs, due to Russian securities regulations providing that no more than 25% of a Russian company's shares may be circulated abroad through sponsored depositary receipt programs. Prior to December 31, 2005 and at the time of our initial public offering, this threshold was 40% and our current ADSs program is near its full capacity. If we cannot obtain adequate funds to satisfy our capital requirements, we may need to limit our operations significantly, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Inflation could increase our costs and adversely affect our results of operations.

The Russian and Ukrainian economies have been characterized by high rates of inflation. According to the Federal Statistics Service, inflation reached 6.6% and 6.5% in Russia in 2012 and 2013, respectively. In Ukraine, deflation amounted to 0.2% in 2012, as compared to inflation of 0.5% in 2013, according to the State Statistics Committee of Ukraine (calculated on a December to December basis). Inflation in 2014 is expected to be in the range of 12-14% due to currency devaluation and significant increases in utility tariffs. As we tend to experience inflation-driven increases in certain of our costs, which are sensitive to rises in the general price level in Russia and Ukraine, our costs will rise. In addition, media inflation in Russia continues to be very high and shows little sign of slowing, which may lead to higher marketing expenditures by us in order to remain competitive. In this situation, due to competitive pressures, we may not be able to raise the prices we charge for our products and services sufficiently to preserve operating margins. Accordingly, high rates of inflation in Russia and Ukraine could increase our costs and decrease our operating margins. See also "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Inflation."

The three-year cumulative inflation rate for Belarus exceeded 100 percent as of September 30, 2011 and continues to exceed 100 percent, thereby meeting the quantitative requirement under U.S. GAAP for its economy to be considered highly inflationary, and we have accordingly accounted for this in our financial statements. See Note 2 to our audited consolidated financial statements. Since most of our revenues in Belarus are denominated in local currency, the devaluation has resulted in lower revenues in Russian ruble terms. Additionally, since a significant portion of our operating costs are denominated or tied to foreign currency, the devaluation and high inflation have also resulted in higher operating costs in comparison to revenues. Accordingly, the devaluation and the highly inflationary economy in Belarus may materially adversely affect our revenues and results of operations in that country. See also "—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies" and "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

If Apple Sales International lodges a claim against us as a result of our failure to fulfill our iPhone handset purchase commitment, this could have a material adverse effect on our financial condition and results of operations.

In 2008, we entered into an unconditional purchase agreement with Apple Sales International to buy certain quantities of iPhone handsets at list prices at the dates of the respective purchases for the three year period. The purchase agreement terminated on September 30, 2012. Pursuant to the agreement, we were also to incur certain iPhone promotional costs. We did not fulfill our total purchase installment contemplated by the agreement. As a result of not having fulfilled our required purchase commitments under our agreement with Apple Sales International, it is possible that Apple Sales International may bring a claim against us, which could have a material adverse effect on our financial condition and results of operations. A reasonable estimate of any potential loss with respect to the remotely possible claim cannot be made.

The total amount paid for handsets purchased under the agreement for the years ended December 31, 2012, 2011, 2010, 2009 and 2008 amounted to $81.8 million, $140.8 million, $79.4 million, $3.4 million and $65.4 million, respectively.

Indentures relating to some of our notes contain, and some of our loan agreements and Sistema's loan agreements contain, restrictive covenants, which limit our ability to incur debt and to engage in various activities.

Covenants in the loan agreement relating to our notes due 2020 limit our ability to create liens on our properties, merge or consolidate with another person or convey our properties and assets to another person. Additionally, the loan agreement contains covenants limiting our ability to incur debt, create liens on our properties, enter into sale and lease-back transactions, merge or consolidate with another person or convey our properties and assets to another person, as well as our ability to sell or transfer any of our or our subsidiaries' GSM licenses for the Moscow, St. Petersburg, Krasnodar and Ukraine license areas. Some of our loan agreements contain similar and other covenants, including, in relation to the incurrence of indebtedness, creation of liens and disposal of assets. Failure to comply with these covenants could cause a default and result in the debt becoming immediately due and payable, which would materially adversely affect our business, financial condition and results of operations.

In addition, Sistema, which owns 51.46% of our total charter capital (53.47% excluding treasury shares) and consolidates our results in its financial statements, is subject to various covenants in its credit facilities. These covenants impose restrictions on Sistema and its restricted subsidiaries (including us) with respect to, inter alia, incurrence of indebtedness, creation of liens and disposal of assets. In the indentures, Sistema undertakes that it will not, and will not permit its restricted subsidiaries (including us) to, incur indebtedness unless a certain debt/EBITDA (as defined therein) ratio is met. In addition to us, Sistema has various other businesses that require capital and, therefore, the consolidated Sistema group's capacity to incur indebtedness otherwise available to us could be diverted to its other businesses. Sistema may also enter into other agreements in the future that may further restrict it and its restricted subsidiaries (including us) from engaging in these and other activities. We expect Sistema to exercise its control over us in order for Sistema, as a consolidated group, to meet its obligations under its current and future financings and other agreements, which could materially limit our ability to obtain additional financing required for the implementation of our business strategy. The inability to implement our business strategy may have a material adverse effect on our financial condition and results of operations.

If a change in control occurs, our noteholders and other debt holders may require us to redeem notes or other debt, which could have a material adverse effect on our financial condition and results of operations.

Under the terms of our outstanding notes, if a change in control occurs, our noteholders will have the right to require us to redeem notes not previously called for redemption. The price we will be required to pay upon such event will be 101% of the principal amount of the notes, plus interest accrued prior to the redemption date. A change in control will be deemed to have occurred in any of the following circumstances:

Some of our loan agreements contain similar change of control provisions. If a change in control occurs, and our noteholders and other debt holders exercise their right to require us to redeem all of their notes or debt, such event could have a material adverse effect on our financial condition and results of operations.

In addition, under certain of our debt agreements, an event of default may be deemed to have occurred and/or we may be required to make a prepayment if Sistema disposes of its stake in our company and a third party takes a controlling position in our company. The occurrence of any such event of default or failure to make any required prepayment which leads to an event of default could trigger cross default/cross acceleration provisions under certain of our other debt agreements. In such event, our obligations under one or more of these agreements could become immediately due and payable, which would have a material adverse effect on our business and our shareholders' equity. If Sistema were to dispose of its stake in us, our company may be deprived of the benefits and resources that it derives from Sistema, which could harm our business.

Economic instability in the countries where we operate could adversely affect our business.

Since the dissolution of the Soviet Union in 1991, the economies of Russia and other CIS countries where we operate have experienced periods of considerable instability and have been subject to abrupt downturns. Most notably, following the Russian government's default on its ruble denominated securities in August 1998, the CBR stopped its support of the ruble and a temporary moratorium was imposed on certain hard currency payments. These actions resulted in the immediate and severe devaluation of the ruble and a sharp increase in the rate of inflation, a substantial decline in the prices of Russian debt and equity securities, and an inability of Russian issuers to raise funds in the international capital markets. These problems were aggravated by the subsequent near collapse of the Russian banking sector, with the termination of banking licenses of a number of major Russian banks. This crisis had a severe impact on the economies of Russia and the other CIS countries.

While the economies of Russia and the other CIS countries where we operate have experienced positive trends in recent years, there has been a slowdown in the growth of gross domestic product in Russia. In 2013 the growth of GDP was 1.3% in comparison with 3.4% in 2012 according to Federal State Statistics service. A financial downturn, as well as any future economic downturns or slowturns in Russia or the other CIS countries where we operate could lead to decreased demand for our services, decreased revenues and negatively affect our liquidity and ability to obtain debt financing, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

The Russian banking system remains underdeveloped, the number of creditworthy banks in Russia is limited and another banking crisis could place severe liquidity constraints on our business.

Russia's banking and other financial systems are less developed or regulated as compared to other countries, and Russian legislation relating to banks and bank accounts is subject to varying interpretations and inconsistent application. The August 1998 financial crisis resulted in the bankruptcy and liquidation of many Russian banks and almost entirely eliminated the developing market for commercial bank loans at that time. Many Russian banks currently do not meet international banking standards, and the transparency of the Russian banking sector in some respects still lags far behind internationally accepted norms. Aided by inadequate supervision by the regulators, certain banks do not

follow existing CBR regulations with respect to lending criteria, credit quality, loan loss reserves or diversification of exposure. Furthermore, in Russia, bank deposits made by corporate entities generally are not insured.

In recent years, there has been a rapid increase in lending by Russian banks, which many believe has been accompanied by a deterioration in the credit quality of the borrowers. In addition, a robust domestic corporate debt market is leading Russian banks (including the banks with which we conduct banking transactions) to hold increasingly large amounts of Russian corporate ruble bonds in their portfolios, which is further deteriorating the risk profile of Russian bank assets. The serious deficiencies in the Russian banking sector, combined with the deterioration in the credit portfolios of Russian banks, may result in the banking sector being more susceptible to market downturns or economic slowdowns, including due to Russian corporate defaults that may occur during any such market downturn or economic slowdown. In addition, the CBR has from time to time revoked the licenses of certain Russian banks, which resulted in market rumors about additional bank closures and many depositors withdrawing their savings. Recently a number of banks and credit institutions have lost their licenses due to deficiency of capital and failure to meet the CBR requirements. If a banking crisis were to occur, Russian companies would be subject to severe liquidity constraints due to the limited supply of domestic savings and the withdrawal of foreign funding sources that would occur during such a crisis.

The recent disruptions in the global markets have generally led to reduced liquidity and increased cost of funding in Russia. Borrowers have generally experienced a reduction in available financing both in the inter-bank and short-term funding market, as well as in the longer term capital markets and bank finance instruments. The non-availability of funding to the banking sector in the Russian Federation has also negatively affected the anticipated growth rate of the Russian Federation. In December 2008, Standard & Poor's lowered Russia's long-term sovereign credit rating to BBB and maintained its negative outlook (as well as Fitch Ratings), citing the "rapid depletion" of Russia's financial reserves. In December 2009, Standard & Poor's changed its outlook on Russia's long-term sovereign credit rating to stable and the same was done by Fitch Ratings in January, 2010. In March 2014 both Standard & Poor's and Fitch Ratings revised the outlook from stable to negative and affirmed the Issuer Default Ratings (IDRs) at BBB. The revision reflects the potential impact of sanctions on Russia's economy and business environment caused by the referendum held in Crimea on March 16, 2014 in favor of joining the Russian Federation and consequent developments in the region. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

The Russian government and the CBR provide financial support only to a limited number of banks, which may result in the liquidation of other banks and financial institutions. Beginning from November 2014, the CBR revoked the licenses of a number of Russian banks for reasons associated with implementing high-risk lending policies, loss of liquidity and non-compliance with anti-money laundering legislation. A combination of these factors may result in a significant deterioration in the financial fundamentals of Russian banks, notably liquidity, asset quality and profitability.

There is currently a limited number of sufficiently creditworthy Russian banks and few ruble-denominated financial instruments in which we can invest our excess ruble cash. We hold the bulk of our excess ruble and foreign currency cash in Russian banks, including subsidiaries of foreign banks. Another banking crisis or the bankruptcy or insolvency of the banks from which we receive or with which we hold our funds could result in the loss of our deposits or 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.

The physical infrastructure in Russia, Ukraine and the other countries where we operate is in poor condition, which could disrupt our normal business activities and adversely impact our results.

The physical infrastructure in Russia, Ukraine and the other countries where we operate largely dates back to Soviet times and has not been adequately funded and maintained over the past two decades. Particularly affected are the rail and road networks, power generation and transmission systems, communication systems and building stock. For example, in August 2009, a major accident occurred at Russia's largest power plant, the Sayano-Shushenskaya hydroelectric power station, resulting in flooding of the engine and turbine rooms, a transformer explosion and the death of 75 people. Power generation from the station ceased completely following the incident, which led to a major power outage in the nearby residential areas and at certain industrial facilities as well as pollution of the rivers and soil as a result of an oil spill from the transformer.

In addition, the road conditions throughout our countries of operation are poor with many roads not meeting minimum quality standards, causing disruptions and delays in the transportation of goods to and within these countries. The Russian and Ukrainian governments are actively considering plans to reorganize their national rail, electricity and communications systems. Any such reorganization may result in increased charges and tariffs while failing to generate the anticipated capital investment needed to repair, maintain and improve these systems. The deterioration of the physical infrastructure in Russia, Ukraine and the other countries where we operate harms the national economies, adds costs to doing business in these countries and generally disrupts normal business activities. These difficulties can impact us directly; for example, we keep portable electrical generators to help us maintain base station operations in the event of power outages. Further deterioration of the physical infrastructure in Russia and Ukraine, as well as the other countries where we operate, could have a material adverse effect on our business, financial condition and results of operations. In addition, the increased charges and tariffs that may result from the government reorganization may also have a material adverse effect on our business, financial condition and results of operations.

Fluctuations in the global economy may materially adversely affect the economies of the countries where we operate and our business in these countries.

The economies of the countries where we operate are vulnerable to market downturns and economic slowdowns elsewhere in the world. As has happened in the past, financial problems or an increase in the perceived risks associated with investing in emerging economies could dampen foreign investment in Russia, Ukraine and elsewhere in the CIS, and businesses in these countries could face severe liquidity constraints, further adversely affecting their economies. Additionally, because Russia and Turkmenistan produce and export large amounts of oil and gas, the Russian and Turkmen economies are especially vulnerable to the price of oil and gas on the world market and a decline in the price of oil and gas could slow or disrupt the Russian and Turkmen economies. Recent military conflicts and international terrorist activity have also significantly impacted oil and gas prices, and pose additional risks to the Russian economy. Russia and Ukraine are also major producers and exporters of metal products and their economies are vulnerable to world commodity prices and the imposition of tariffs and/or antidumping measures by the United States, the European Union or by other principal export markets.

The disruptions recently experienced in the international and domestic capital markets have led to reduced liquidity and increased credit risk premiums for certain market participants and have resulted in a reduction of available financing. Companies located in emerging markets, including us, may be particularly susceptible to these disruptions and reductions in the availability of credit or increases in financing costs. To the extent that the current market downturn continues or worsens, it may lead to constraints on our liquidity and ability to obtain debt financing, which may have a material adverse effect on our business, financial conditions and results of operations.

Political and governmental instability in Russia and other countries of our operations could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

Since 1991, Russia has sought to transform from a one-party state with a centrally planned economy to a democracy with a market economy. As a result of the sweeping nature of the reforms, and the failure of some of them, the Russian political system remains vulnerable to popular dissatisfaction, including dissatisfaction with the results of privatizations in the 1990s, as well as to demands for autonomy from particular regional and ethnic groups. Furthermore, recent parliamentary elections held in December 2011 and presidential elections held in March 2012 led to some political demonstrations in a few Russian cities. New protests may occur in the future. Other countries where we operate may pose similar challenges. For example, mass protests and armed conflicts in Ukraine from November 2013 as well as the referendum in Crimea in favor of joining the Russian Federation and consequent developments in the region contribute to political tension and uncertainty in Ukraine, see also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations." Current and future changes in the Russian and other CIS governments, major policy shifts or lack of consensus between various branches of the government and powerful economic groups could disrupt or reverse economic and regulatory reforms. Any disruption or reversal of reform policies could lead to political or governmental instability or the occurrence of conflicts among powerful economic groups, which could have a material adverse effect on our business, financial condition, results of operations and prospects and the value of our shares and ADSs. A deterioration of the socio-political situation in Russia could also trigger an event of default under some of our loan agreements.

Potential conflict between central and regional authorities could create an uncertain operating environment hindering our long-term planning ability.

The Russian Federation is a federation of sub-federal political units, consisting of republics, territories, regions, cities of federal importance and autonomous regions and districts. The delineation of authority and jurisdiction among the members of the Russian Federation and the federal government is, in many instances, unclear and remains contested. Lack of consensus between the federal government and local or regional authorities could result in the enactment of conflicting legislation at various levels and may lead to political instability. In particular, conflicting laws have been enacted in the areas of privatization, land legislation and licensing. Some of these laws and governmental and administrative decisions implementing them, as well as certain transactions consummated pursuant to them, have in the past been challenged in the courts, and such challenges may occur in the future. This lack of consensus may hinder our long-term planning efforts and create uncertainties in our operating environment, both of which may prevent us from effectively and efficiently implementing our business strategy.

Additionally, ethnic, religious, historical and other divisions have, on occasion, given rise to tensions and, in certain cases, military conflict, which can halt normal economic activity and disrupt the economies of neighboring regions. For example, violence and attacks relating to the Chechen conflict have spread to other parts of Russia and several terrorist attacks have been carried out in other parts of Russia, including Moscow. The further intensification of violence, including terrorist attacks and suicide bombings, or its spread to other parts of Russia, could have significant political consequences, including the imposition of a state of emergency in some or all of Russia. Moreover, any terrorist attacks and the resulting heightened security measures are likely to cause disruptions to domestic commerce and exports from Russia. These factors could materially adversely affect our business and the value of our shares and ADSs.

In Ukraine, tensions between certain regional authorities and the central government were ignited following the November 2004 presidential elections. Amid the mass demonstrations and strikes that took place throughout Ukraine to protest the election process and results, the conference of the representatives of the regional authorities in eastern Ukraine decided to conduct a referendum on creating an autonomous region, separate from Ukraine. Later the regional authorities ultimately backed down from this intention, and tensions in Ukraine subsided. See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

Relations between Russia and certain other former Soviet republics are or have in the past been strained. For example, in August 2008, an armed conflict erupted between Russia and Georgia over the self-appointed republics South Ossetia and Abkhazia, culminating in Russia's recognition of their independence from Georgia. The political and economic relationships between Ukraine and Russia have also been strained in recent years, culminating in the current geopolitical crisis with respect to Crimea. If disputes with Ukraine were to disrupt or reduce the flow of Russia's trade with Ukraine, the Ukrainian economy could be materially adversely affected which in turn could have a material adverse effect on our operations in Ukraine and, consequently, on our financial condition, results of operations and prospects. See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

The conflicts between Russia and other former Soviet republics have, in some instances, also strained Russia's relationship with the United States and the European Union which, at times, has negatively impacted Russia's financial markets. For example, during the course of March 2014, a number of Russian, Ukrainian and Crimean governmental officials and individuals (including representatives of the Russian Parliament), several Russian businessmen and a Russian bank were designated as "Specially Designated Persons" by the U.S. Department of the Treasury, Office of Foreign Assets Control ("OFAC") pursuant to three executive orders signed by the President of the United States. The first and second executive orders (Nos. 13660 and 13661) targeted former Ukrainian officials and current Russian Federation officials, as well as persons who operate in the arms or related sectors in the Russian Federation. The third executive order (No. 13662) significantly expanded the scope of the prior two executive orders by providing OFAC the authority to block the property of designated persons who operate in certain sectors of Russia's economy, including financial services, energy, metals and mining, engineering, defense and related sectors, although no such persons have been designated as a Specially Designated Person pursuant to this third, and much more expansive, order. The Council of the EU introduced a similar list of persons that are subject to EU sanctions with the exception of Russian businessmen and the Russian bank.

There is still significant uncertainty regarding the extent or timing of any further political or economic sanctions, or the ultimate impact of the Ukrainian crisis on Russia's relationship with Ukraine, the United States or the European Union. Any further sanctions may have a negative effect on the Russian economy, the financial condition of our partners and suppliers, our ability to conduct trade and financial transactions, our ability to obtain financing on commercially reasonable terms, and the level and volatility of the trading price of our shares and ADSs. Any of the foregoing circumstances could have a material adverse effect on our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

See also "—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the

countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" and "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations.

Economic crisis, deterioration of key aspects of the economy and the lack of investment social infrastructure, has, amongst other things, led to the instability of the political situation in Ukraine where we have significant operations. Furthermore, the refusal of the Ukrainian Government to enter into an association agreement with the European Union in November, 2013 incited mass protests in Kiev and other regions of the country. These protests caused, amongst other things, a downgrade of Ukraine's international ratings and significant depreciation of the national currency, see "—Risks Relating to our Financial Condition—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies."

On January 28, 2014, the Ukrainian government resigned and a new government was formed and on March 16, 2014, a referendum in favor of joining the Russian Federation was held in Crimea. These events have resulted in heightened tensions between Ukraine and the Russian Federation and have created legal uncertainties in the affected regions which may impact our business. Furthermore, should tensions between the Russian Federation and Ukraine continue or increase, or should the economic and political situation in Ukraine become further destabilized, our business interests in Ukraine, Crimea and other impacted regions may be adversely affected or targeted.

The continued impact of these events and any continuing or escalating military action, public protests, unrest, political instability or further sanctions could have a further adverse effect on our business in Ukraine, our financial condition and reputation. See also "—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

Crime and corruption could disrupt our ability to conduct our business and thus materially adversely affect our operations.

The political and economic changes in recent years in the countries where we operate have resulted in significant dislocations of authority. The local and international press have reported the existence of significant organized criminal activity, particularly in large metropolitan centers. Property crime in large cities has increased substantially. In addition, the local and international press have reported high levels of corruption, including the bribing of officials for the purpose of initiating investigations by government agencies. Press reports have also described instances in which government officials engaged in selective investigations and prosecutions to further the commercial interests of certain government officials or certain companies or individuals. Additionally, some members of the media in the countries we operate in regularly publish disparaging articles in return for payment. The depredations of organized or other crime, demands of corrupt officials or claims that we have been involved in official corruption could result in negative publicity, disrupt our ability to conduct our business and could thus materially adversely affect our business, financial condition, results of operations and prospects.

Social instability could increase support for renewed centralized authority, nationalism or violence and thus materially adversely affect our operations.

A decrease in the price of oil, as well as increased unemployment rates, the failure of the government and many private enterprises to pay full salaries on a regular basis and the failure of salaries and benefits generally to keep pace with the rapidly increasing cost of living have led in the past, and could lead in the future, to labor and social unrest. Labor and social unrest may have political, social and economic consequences, such as increased support for a renewal of centralized authority; increased nationalism, including restrictions on foreign involvement in the economies of the countries where we have operations; and increased violence. An occurrence of any of the foregoing events could restrict our operations and lead to the loss of revenues, materially adversely affecting our operations. See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

Weaknesses relating to the legal system and legislation in the countries where we operate create an uncertain environment for investment and business activity, which could have a material adverse effect on the value of our shares and ADSs.

Each of the countries we operate in is still developing the legal framework required to support a market economy. The following risk factors relating to these legal systems create uncertainty with respect to the legal and business decisions that we make, many of which uncertainties do not exist in countries with more developed market economies:

The recent nature of much of the legislation in the CIS countries, the lack of consensus about the scope, content and pace of economic and political reform and the rapid evolution of these legal systems in ways that may not always coincide with market developments place the enforceability and underlying constitutionality of laws in doubt and result in ambiguities, inconsistencies and anomalies. In addition, legislation in these countries often contemplates implementing regulations that have not yet been promulgated, leaving substantial gaps in the regulatory infrastructure. All of these weaknesses could affect our ability to enforce our rights under our licenses and contracts, or to defend ourselves against claims by others. Moreover, it is possible that regulators, judicial authorities or third parties may challenge our internal procedures and bylaws, as well as our compliance with applicable laws, decrees and regulations.

The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations.

If we are unable to protect our business entities in the countries in which we operate from the withdrawal or suspension or regulatory scrutiny, this may adversely affect our business, financial condition and results of operations. For example, in June 2012, the authorities of the Republic of Uzbekistan began audits of the financial and operating activities of MTS' wholly-owned subsidiary Uzdunrobita. On July 17, 2012 Uzdunrobita suspended its services in Uzbekistan upon receipt of an order from the State Agency for Communications and Information of Uzbekistan ("SACI") on the temporary suspension of the operating license of Uzdunrobita for a period of 10 business days; this suspension was subsequently extended to three months.

On August 6-7, 2012, fourteen regional antimonopoly departments of the Republic of Uzbekistan simultaneously held hearings and declared that Uzdunrobita had violated antimonopoly laws, consumer protection laws and laws governing advertisements. In total, the claims of the regional antimonopoly departments against Uzdunrobita amounted to approximately $80.0 million (RUB 2,558 million). This amount was subsequently reduced by the superior antimonopoly regulator to $13.0 million (RUB 416 million) in aggregate. The disputes with the antimonopoly authorities were dismissed further to payments made by Uzdunrobita under the Appeal Decision (as defined below).

On August 13, 2012, the Tashkent Economic Court granted a petition filed by the SACI to terminate all operating licenses of Uzdunrobita. This decision was subsequently upheld by the appellate and cassation courts on August 27, 2012 and April 4, 2013, respectively.

Notwithstanding the fact that a tax audit of Uzdunrobita's operations for the period of 2007-2010 had been completed in February 2012 and had not revealed any serious violations, Uzdunrobita was assessed pursuant to subsequent additional tax audits into alleged licensing regulation violations, income and other taxes to be liable for approximately $900.0 million (RUB 28,776 million). This amount was subsequently reduced to $669.0 million (RUB 21,390 million) in aggregate. All tax disputes are now closed.

During September-October 2012, $6.4 million (RUB 201 million) from Uzdunrobita's bank accounts were withdrawn by the Uzbek state tax authorities to settle its alleged liabilities under these claims.

On September 17, 2012, the Tashkent City Criminal Court issued a ruling to confiscate all assets of Uzdunrobita in connection with a criminal court judgment against four employees of Uzdunrobita. Previously, Uzbek law enforcement bodies arrested all of Uzdunrobita's assets, including cash held in local bank accounts.

On November 8, 2012, the Appellate division of the Tashkent City Criminal Court allowed Uzdunrobita's appeal challenging the decision of the Tashkent City Criminal Court dated September 17, 2012 and determined that the total amount of damages incurred by the state was to be compensated by Uzdunrobita. This amount of damages was calculated and determined on the basis of all the aforementioned claims against Uzdunrobita and amounted to $587 million (RUB 18,375 million) payable in equal installments over eight months (the "Appeal Decision").

In accordance with the applicable Uzbek laws, Uzdunrobita petitioned the Deputy General Prosecutor to appeal the Appeal Decision in the Supreme Court of Uzbekistan and grant a stay to enforce the Appeal Decision. However, such petitions were rejected by the General Prosecutor's Office on January 8, 2013.

Further to such rejection, Uzdunrobita immediately filed similar requests to the Chairman of the Supreme Court of Uzbekistan. However, on January 23, 2013, Uzdunrobita was notified that the matter had been submitted by the Supreme Court for consideration by the Chairman of the Tashkent City

Court. On May 2, 2013, the Chairman of the Tashkent City Court rejected Uzdunrobita's petition. In order to comply with the Appeal Decision, Uzdunrobita then paid two scheduled installments in November and December 2012 totaling $147.5 million (RUB 4,583.4 million). On January 14, 2013, further to its partial payment of the third installment due in January 2013 totaling $15.9 million (RUB 481 million) and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the grounds of its inability to meet further obligations pursuant the Appeal Decision. The court initiated bankruptcy proceedings and appointed an external temporary supervisor over Uzdunrobita with the further bankruptcy hearing took place on April 22, 2013.

On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated a six month liquidation period which, following its extension, we currently believe to be still in place. In accordance with the terms of local liquidation procedures, Uzdunrobita's CEO was relieved from his duties and all oversight and governance over Uzdubrobita was transferred to the liquidation administrator. As a result, the Group had lost control over its subsidiary and deconsolidated Uzdunrobita.

During July 1-31, 2013, two rounds of auctions were set and held in relation to the sale of assets of Uzdunrobita and all of its branches. All auctions were recognized as having failed due to the absence of any applications by any interested bidders.

As far as we understand, Uzdunrobita's (including its branches') assets have been transferred to the balances of municipal bodies of Uzbekistan under the supervision of employees from Uztelecom, the national telecom operator.

We believe that the claims of the Uzbek state authorities against Uzdunrobita and which resulted in the initiation of its bankruptcy are unfounded. The Group reserves all of its rights to pursue all available legal options in Uzbekistan and internationally to defend its legal rights and protect its investments and to fully recover damages or obtain other relief including from any party involved in depriving MTS of its business and assets in Uzbekistan.

We filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes (ICSID), part of the World Bank Group, in Washington, D.C. which was registered on November 15, 2012. The tribunal was formed on August 29, 2013 and the first procedural hearings took place in November 2013. See also "Political and Social Risks—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs" and "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

The inability of MTS Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations.

In December 2010, the Group suspended its operations in Turkmenistan following notification by the Ministry of Communications of Turkmenistan of a decision to suspend licenses held by BCTI, the Group's wholly-owned subsidiary in Turkmenistan, for a period of one month starting from December 21, 2010. On January 21, 2011, the period of license suspension expired, however, permission to resume operations was not granted.

The Group operated in Turkmenistan under a trilateral agreement signed in November 2005 by BCTI, MTS OJSC and the Ministry of Communications of Turkmenistan valid for a period of five years with a possibility to extend its term. In accordance with certain provisions of this agreement, BCTI

shared net profits derived from its operations in the country with the Ministry of Communications of Turkmenistan.

Following the decision to suspend BCTI's licenses, Turkmenistan government authorities took further steps, including unilateral termination of interconnect agreements between BCTI and state-owned telecom operators, to prevent the Group from providing services to its customers.

We initiated a number of proceedings against Turkmenistan government authorities and state-owned telecom operators to defend our legal rights. At this time, we were also negotiating to settle the disputes on an amicable basis. On May 24, 2012 we concluded an agreement with the state-owned telecom operator Turkmentelekom relating to our terms of operations in Turkmenistan which resulted from negotiations between the Turkmenistan government and ministries. The agreement has a five year term and can be extended for next five years provided certain terms and conditions are satisfied. Under this agreement we are obliged to pay Turkmentelekom a monthly amount calculated as 30% of our net profit in Turkmenistan based on accounting rules of Turkmenistan. We also received GSM and 3G licenses for a term of three years (with possibility of prolongation), signed several agreements with the state-owned telecom operators regarding the cooperation upon infrastructure that allows us to restart the network and started to provide services to subscribers.

On July 25, 2012, we, our subsidiary BCTI, the republic of Turkmenistan, the Ministry of Communications of Turkmenistan, the state-owned company Turkmentelecom and mobile operator Altyn Asyr signed a settlement agreement (including the dismissal of all international lawsuits) concerning the suspension of our operations in Turkmenistan in December 2010.

In August 2012, we restarted our mobile communication network in Turkmenistan and resumed providing services for subscribers who had not canceled their contracts. Since October 1, 2012 we resumed our operations in Turkmenistan entirely and started entering into contracts with new subscribers.

Russian and Ukrainian companies can be forced into liquidation on the basis of formal non-compliance with certain legal requirements.

Certain provisions of Russian law may allow government authorities to seek a court order for the liquidation of a Russian legal entity on the basis of its formal non-compliance with certain requirements during formation, reorganization or during its operation.

For example, under Russian corporate law, if the net assets of a Russian joint stock company calculated on the basis of Russian accounting standards are lower than its charter capital as at the end of its third or any subsequent financial year, the company must either decrease its charter capital or be placed in liquidation. If the company fails to comply with these requirements, governmental or local authorities can seek the involuntary liquidation of such company in court, and the company's creditors will have the right to accelerate their claims or demand early performance of the company's obligations as well as demand compensation of any damages.

The existence of negative assets may not accurately reflect the actual ability to pay debts as they fall due. Many Russian companies have negative net assets due to very low historical asset values reflected on their Russian accounting standards balance sheets; however, their solvency, i.e., their ability to pay debts as they fall due, is not otherwise adversely affected by such negative net assets. Some Russian courts, in deciding whether or not to order the liquidation of a company for having negative net assets, have looked beyond the fact that the company failed to fully comply with all applicable legal requirements and have taken into account other factors, such as the financial standing of the company and its ability to meet its tax obligations, as well as the economic and social consequences of its liquidation. Nonetheless, creditors have the right to accelerate claims, and file damages claims, and governmental or local authorities may seek the liquidation of a company with negative net assets.

Courts have, on rare occasions, ordered the involuntary liquidation of a company for having net assets less than the minimum charter capital required by law, even if the company had continued to fulfill its obligations and had net assets in excess of the minimum charter capital at the time of liquidation.

The amount of net assets in accordance with the local accounting standards of some of our subsidiaries is negative. Although these subsidiaries continue to meet all of their obligations to creditors, there is a minimal risk of their liquidation while the net assets remain below the minimum legal requirements.

There have also been cases in the past in which formal deficiencies in the establishment process of a Russian legal entity or non-compliance with provisions of Russian law have been used as a basis to seek the liquidation of a legal entity. Weaknesses in the Russian legal system create an uncertain legal environment, which makes the decisions of a Russian court or a governmental authority difficult, if not impossible, to predict. If involuntary liquidation were to occur, such liquidation could lead to significant negative consequences for our group. Ukrainian law also contains provisions similar to Russian law, whereby a company's failure to comply with certain legal requirements concerning its formation, net assets or operation may be grounds for its liquidation.

Insufficient adherence to the independence and competitiveness of the judicial process, the difficulty of enforcing court decisions and governmental discretion in enforcing claims could prevent us or holders of our securities from obtaining effective redress in a court proceeding.

The judicial bodies in the countries where we operate are not always completely independent or immune from economic and political influences, and are often understaffed and underfunded. Judges and courts are often inexperienced in the area of business, corporate and industry (telecommunications) law. Judicial precedents generally have no binding effect on subsequent decisions, and not all court decisions are readily available to the public or organized in a manner that facilitates understanding. The judicial systems in these countries can also be slow or unjustifiably swift. Enforcement of court orders can, in practice, be very difficult to achieve. All of these factors make judicial decisions in these countries difficult to predict and effective redress uncertain. Additionally, court claims are often used in furtherance of political and commercial aims or infighting. We may be subject to such claims and may not be able to receive a fair hearing. Additionally, court orders are not always enforced or followed by law enforcement agencies. Furthermore, recognition and enforcement of arbitral awards in countries where we operate is subject to compliance with corresponding rules of civil procedure and applicable laws, and courts in countries where we operate may interpret applicable regulations in a manner which would result in denial of such recognition and enforcement.

These uncertainties also extend to property rights. For example, during Russia and Ukraine's transformation from centrally planned economies to market economies, legislation has been enacted in both countries to protect private property against uncompensated expropriation and nationalization. However, there is a risk that due to the lack of experience in enforcing these provisions and due to political factors, these protections would not be enforced in the event of an attempted expropriation or nationalization. Expropriation or nationalization of any of our entities, their assets or portions thereof, potentially without adequate compensation, would have a material adverse effect on our business, financial condition, results of operations and prospects.

Selective or arbitrary government action could have a material adverse effect on our business, financial condition, results of operations and prospects.

Governmental authorities in the countries where we operate have a high degree of discretion and, at times, act selectively or arbitrarily, without hearing or prior notice, and sometimes in a manner that is inconsistent with legislation or influenced by political or commercial considerations.

Selective or arbitrary governmental actions have reportedly included the denial or withdrawal of licenses, sudden and unexpected tax audits and claims, criminal prosecutions and civil actions. Federal and local government entities have also used ordinary defects in matters surrounding share issuances and registration as pretexts for court claims and other demands to invalidate such issuances and registrations or to void transactions. Moreover, the government also has the power in certain circumstances, by regulation or government acts, to interfere with the performance of, nullify or terminate contracts. Standard & Poor's has expressed concerns that "Russian companies and their investors can be subjected to government pressure through selective implementation of regulations and legislation that is either politically motivated or triggered by competing business groups." In this environment, our competitors may receive preferential treatment from the government, potentially giving them a competitive advantage over us.

In Turkmenistan, we commenced operations in June 2005 through our wholly owned subsidiary, BCTI, and operated under a trilateral agreement by and among the Ministry of Communication of Turkmenistan, BCTI and us. However, when this agreement expired on December 21, 2010, the Ministry of Communication of Turkmenistan refused to prolong the agreement. After several international lawsuits and negotiations regarding adjustments of disputes we restarted our network in Turkmenistan on August 30, 2012 and resumed our operations on October 1, 2012. Similar actions in other countries where we operate could have a material adverse effect on results of our operations. See also "—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations."

In addition, the Russian tax authorities have aggressively brought tax evasion claims relating to Russian companies' use of tax-optimization schemes, and press reports have speculated that these enforcement actions have been selective and politically motivated. Selective or arbitrary government action, if directed at us, could have a material adverse effect on our business, financial condition, results of operations and prospects.

Failure to comply with existing laws and regulations or to obtain all approvals, authorizations and permits required to transmit television channels or operate telecommunications equipment, or the findings of government inspections or increased governmental regulation of our operations, could result in a disruption in our business and substantial additional compliance costs and sanctions.

Our operations and properties are subject to regulation by various government entities and agencies in connection with obtaining and renewing various licenses, approvals, authorizations and permits, as well as with ongoing compliance with existing laws, regulations and standards. Regulatory authorities exercise considerable discretion in matters of enforcement and interpretation of applicable laws, regulations and standards, the issuance and renewal of licenses, approvals, authorizations and permits and in monitoring licensees' compliance with the terms thereof. Russian authorities have the right to, and frequently do, conduct periodic inspections of our operations and properties throughout the year. Any such future inspections may conclude that we or our subsidiaries have violated laws, decrees or regulations, and we may be unable to refute such conclusions or remedy the violations. See also "—The regulatory environment for telecommunications in Russia, Ukraine and other countries where we operate or may operate in the future is uncertain and subject to political influence or manipulation, which may result in negative and arbitrary regulatory and other decisions against us on the basis of other than legal considerations and in preferential treatment for our competitors."

Primarily due to delays in the issuance of permits, approvals and authorizations by regulatory authorities, it is frequently not possible to procure all of the permits for each of our base stations or other aspects of our network before we put the base stations into commercial operation or to amend or

maintain all of the permits when we make changes to the location or technical specifications of our base stations. At times, there can be a significant number of base stations or other communications facilities and other aspects of our networks for which we do not have final permits to operate and there can be delays in obtaining the final permits, approvals and authorizations for particular base stations or other communications facilities and other aspects of our networks.

In addition, we may be unable to transmit certain television channels if entities that provide television content to us do not possess the requisite licenses. In case such providers of television content do not obtain the required licenses, or have their existing licenses suspended or terminated, our selection of potential television channels for transmission could be significantly limited. Furthermore, we could be subject to fines and other penalties, including forced suspension of our cable network operators' activity for up to 90 days. In some cases of our service provision (for example, those employing GPON technology) power failures in subscribers' households may lead to non-compliance with rules regulating local telephony communication services. Any of these consequences could have a material adverse effect on our business, financial condition and results of operations.

Our failure to comply with existing laws and regulations or to obtain all approvals, authorizations and permits required to operate telecommunications equipment, or the findings of government inspections including the State Labor Inspection Service may also result in the imposition of fines or penalties or more severe sanctions including the suspension, amendment or termination of our licenses, approvals, authorizations and permits, or in requirements that we cease certain of our business activities, or in criminal and administrative penalties applicable to our officers. Moreover, an agreement or transaction entered into in violation of Russian law may be invalidated and/or unwound by a court decision. Any such decisions, requirements or sanctions, or any increase in governmental regulation of our operations, could result in a disruption of our business and substantial additional compliance costs and could materially adversely affect our business, financial condition, results of operations and prospects. In addition, following our integration with Comstar on April 1, 2011 we have assumed risks of potential claims from subscribers and regulating authorities regarding the former activities of Comstar.

The level of development of corporate and securities laws and regulations in Russia could limit our ability to attract future investment.

The regulation and supervision of the securities market, financial intermediaries and issuers are less developed in Russia than, for example, in the United States and Western Europe. Securities laws, including those relating to corporate governance, insider trading, disclosure and reporting requirements, are relatively new, while other laws concerning anti-fraud and directors' and officers' liabilities remain underdeveloped. The Russian securities market is regulated by the CBR and FAS where the latter oversees anti-monopoly matters and advertisement relating to securities.

In addition, Russian corporate and securities rules and regulations can change rapidly, which may materially adversely affect our ability to conduct capital markets transactions. While some important areas are subject to virtually no oversight, the regulatory requirements imposed on Russian issuers in other areas result in delays in conducting securities offerings and in accessing the capital markets. It is often unclear whether or how regulations, decisions and letters issued by the various regulatory authorities apply to us. As a result, we may be subject to fines and/or other enforcement measures despite our best efforts at compliance, which could have a material adverse effect on our business, financial condition and results of operations.

Minority shareholder protection under Russian law principally derives from supermajority shareholder approval requirements for certain corporate actions, as well as from the ability of a

shareholder to demand that the company purchase the shares held by that shareholder if that shareholder voted against or did not participate in voting on certain types of actions. Companies are also required by Russian law to obtain the approval of disinterested shareholders for certain transactions with interested parties. In practice, enforcement of these protections has been poor. Shareholders of some companies have also suffered as a result of fraudulent bankruptcies initiated by hostile creditors.

The supermajority shareholder approval requirement is met by a vote of 75% of all voting shares that are present at a shareholders' meeting. Thus, controlling shareholders owning slightly less than 75% of outstanding shares of a company may have a 75% or more voting power if certain minority shareholders are not present at the meeting. In situations where controlling shareholders effectively have 75% or more of the voting power at a shareholders' meeting, they are in a position to approve amendments to the charter of the company or significant transactions including asset transfers, which could be prejudicial to the interests of minority shareholders. It is possible that our controlling shareholder in the future may not operate us and our subsidiaries for the benefit of minority shareholders, and this could have a material adverse effect on the value of our shares and ADSs.

While the Federal Law on Joint Stock Companies of December 26, 1995, (the "Joint Stock Companies Law") provides that shareholders owning not less than 1% of the company's stock may bring an action for damages caused to a company by its CEO, member of the Board of Directors or is Management Board and certain other officials, minority shareholders may have difficulties with proving such damages with the court and as a consequence may be denied their claims by the court. In 2009, new legislation was adopted which contemplates class action litigation. However, since the legislation is relatively new, Russian courts are not experienced in resolving such disputes and do not have a clear and consistent approach in regards to class action litigation. Accordingly, your ability to pursue legal redress against us may be limited, reducing the protections available to you as a holder of our shares and ADSs.

Shareholder liability under Russian legislation could cause us to become liable for the obligations of our subsidiaries.

The Civil Code of the Russian Federation, the Joint Stock Companies Law and the Federal Law "On Limited Liability Companies" generally provide that shareholders in a Russian joint stock company or members of a limited liability company are not liable for the obligations of the company and bear only the risk of loss of their investment. This may not be the case, however, when one entity is capable of determining decisions made by another entity. The entity capable of determining such decisions is deemed an "effective parent." The entity whose decisions are capable of being so determined is deemed an "effective subsidiary." The effective parent bears joint and several responsibility for transactions concluded by the effective subsidiary in carrying out these decisions if:

In addition, an effective parent is secondarily liable for an effective subsidiary's debts if an effective subsidiary becomes insolvent or bankrupt resulting from the action or inaction of an effective parent. This is the case no matter how the effective parent's ability to determine decisions of the effective subsidiary arises. For example, this liability could arise through ownership of voting securities or by contract. In these instances, other shareholders of the effective subsidiary may claim compensation for the effective subsidiary's losses from the effective parent which caused the effective subsidiary to take action or fail to take action knowing that such action or failure to take action would result in losses. Accordingly, we could be liable in some cases for the debts of our subsidiaries. This

liability could have a material adverse effect on our business, results of operations and financial condition.

Shareholder rights provisions under Russian law could impose additional obligations and costs on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Russian law provides that shareholders that vote against or did not participate in voting on certain matters have the right to sell their shares to the company at market value in accordance with Russian law. The decisions that trigger this right to sell shares include:

For example, from 2004 through March 31, 2013, we merged over 45 of our wholly owned subsidiaries into MTS. Following the approval of the first of the series of mergers we repurchased shares from investors who voted against or abstained from voting on the merger in the amount of 11.1 billion rubles ($446.3 million as of the date of repurchase). Also, on March 10, 2011, we completed a share buyback as part of the reorganization of MTS involving a merger with Comstar, Dagtelecom and Evrotel. Specifically, a total of 8,000 MTS ordinary shares representing 0.0004% of our issued share capital were repurchased for RUB 1.96 million ($67,000 as of the date of repurchase). In addition, a total of 22,483,791 Comstar ordinary shares representing 5.3809% of ssued share capital were repurchased for RUB 4.8 billion ($161.3 million as of the date of repurchase). Also as a part of our reorganization during 2013 a total of 90,881 MTS ordinary shares representing 0.004% of our issued share capital were repurchased for RUB 19.7 million (approximately $650,000 as of March 31, 2013).

Our obligation to purchase shares in these circumstances, which is limited to 10% of the company's net assets calculated in accordance with Russian accounting standards at the time the matter at issue is voted upon, could have a material adverse effect on our business, financial condition, results of operations and prospects. Under Russian law, if we are unable to sell the repurchased shares at a price equal to or exceeding the market price within one year after the date of repurchase, we have to reduce our charter capital accordingly.

The Strategic Foreign Investment Law imposes certain restrictions on us and our existing and potential foreign shareholders, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

On May 7, 2008, the Federal Law "On the Procedure for Foreign Investment in Commercial Organizations of Strategic Importance for the Defense and Security of the State," or the Strategic Foreign Investment Law, came into force in Russia. This law sets forth certain restrictions relating to foreign investments in Russian companies of "strategic importance." Among others, companies with a dominant position in the Russian telecommunications market are considered to be strategically important and foreign investments in such companies are subject to regulations and restrictions to these companies set out by the Strategic Foreign Investment Law. For purposes of the Strategic Foreign Investment Law, a mobile telecommunications provider is deemed to be dominant if its market share in the Russian market exceeds 25%, as may be determined by FAS. In addition, a company may be

considered to be strategically important due to our offering of services involving the use of cryptographic technologies.

On April 8, 2009, MTS and two of our subsidiaries, Dagtelecom LLC (Dagtelecom LLC has since been merged into MTS) and Sibintertelecom CJSC, were added to the register of companies occupying a dominant position on the market with a market share exceeding 25% for the purpose of the Strategic Foreign Investment Law.

Starting from the effective date of the Strategic Foreign Investment Law, a foreign investor seeking to obtain direct or indirect control over a strategically important company is required to have the respective transaction pre-approved by an authorized governmental agency. In addition, foreign investors are required to notify this authorized governmental agency about any transactions undertaken by them resulting in the acquisition of 5% or more of the charter capital of strategically important companies. Within 180 days from the effective date of the Strategic Foreign Investment Law, foreign investors having 5% or more of the charter capital of strategically important companies were required to notify the authorized governmental agency about their current shareholding in such companies.

As we are classified as a strategically important company, our current and future foreign investors are subject to the notification requirements described above and our current and potential investors may be limited in their ability to acquire a controlling stake in, or otherwise gain control over, us. Such increase in governmental control or limitation on foreign investment could impair the value of your investment and could hinder our access to additional capital.

Regulatory changes in Russia, including the reduction of settlement rate, the mobile number portability principle and others may have a material adverse effect on our financial condition and results of operations.

Following an amendment to the Federal Law on Communications, which became effective July 1, 2006, fixed line operators began charging their subscribers for calls to mobile phone users and started to transfer a percentage of the charge to mobile operators terminating such calls. The percentage transferred to mobile operators is established by the regulator and is known as the "settlement rate." The Ministry of Communications and Mass Media is considering altering the approach to inter-carrier settlements in Russia and the subsequent lowering of the settlement rate. Any reduction of the settlement rate by the regulator could have a negative impact on our average monthly service revenues per subscriber and margins. In September 2013, a commission on telecommunications with the Government of Russia supported the proposal of the Ministry of Communications and Mass Media to simplify the process of traffic transmission within one sub-federal region. The Ministry of Communications and Mass Media is expected to present certain suggestions to the government in the second quarter of 2014. The exact changes to the current regulations may be significant, including the regulation of interconnect leading to operators' inability to determine the autonomous pricing of interconnect rates.

In January 2013, the Ministry of Communications and Mass Media held open discussions as part of its efforts to develop a revamped version of the Federal Law on Communications. Ministry officials propose to amend the law in order to minimize operators' expenditures on infrastructure development by introducing unified licenses for communications, without linking them to certain technologies and other similar means. Frequencies are proposed to be granted on the basis of auctions instead of competitive selection.

The adoption of the law regarding the ability of a subscriber to retain the telephone number after switching from one operator of mobile communications to another (mobile number portability ("MNP") may lead to intensification of competition and an increase in our costs. This law was signed by the President of the Russian Federation on December 25, 2012 and came into legal force on December 1, 2013. To enable subscribers to use MNP, a certain number of regulatory legal acts were passed. Moreover, the introduction of MNP would impose additional costs on the operators of mobile

communications due to the necessity of implementing several complex and resource-intensive actions involving organizational and technical infrastructure, the requirement to improve the software of telecommunication facilities, and change certain business processes. The costs could also further increase in instances where subscribers, including corporate clients, switch to another mobile communications operator before finalizing the settlement for services, including international roaming and other high value services, with us.

There are various difficulties that we face in implementing MNP principle including difficulties in applying established customer practices. The implementation of the MNP principle may therefore lead to the interference of antimonopoly authorities and legal actions. For example, MegaFon filed a claim against us after winning a contract on rendering services to the members of the Council of the Federation. The claim is under consideration of FAS. The first meeting was held on April 7, 2014 and the forthcoming is scheduled on April 24, 2014.

From March 1, 2014, if an operator fails to pass a subscriber's number to another operator it will be obliged to render the services free of charge. The duration of any free of charge services will start from the planned date of passing the number until the effective date of the transfer. This initiative came into force on March 1, 2014 and placed additional responsibility on the operators whilst exposing operators to the risk that certain subscribers may seek to improperly take advantage of this system by engineering delays in the MNP process. Starting from April 8, 2014, the operators are obliged to pass a subscriber's number to another operator no later than the eighth day from the individual subscriber's application date and on the twenty ninth day in case the subscriber is a legal entity, unless otherwise indicated in the subscriber's application.

The new version of the Federal Law on Information, Information Technologies and Information Security may classify our information systems as critically important, which would involve the need to comply with additional information security requirements and could lead to considerable modernization costs. There is also a possible necessity of replacing foreign information security products with locally developed substitutes.

Moreover, recently a draft law regulating the equipment used in telecommunications network was introduced for consideration by the State Duma of the Russian Federation. This draft law would require us to use telecommunications equipment produced by Russian companies (i.e. those which are tax residents of the Russian Federation). The software in such equipment should have open source code. The draft law permits the use of foreign equipment in case there is no similar equipment produced by Russian companies. It is not yet clear how the restrictions can be applied since there are no Russian producers of much of this equipment. If this draft law is adopted, we could encounter severe difficulties in our operations.

The draft version of the Rules of rendering the telephone communications services which was set for discussion on March 12, 2014, includes several amendments. These include an obligation for operators to inform the subscribers of any changes in tariff plans via sms, the inability of operators to charge subscribers for switching to another tariff plan as well as the possibility of subscribers to demand back the advance payments made without termination of contract. In case the draft version of the Rules is adopted it could materially adversely affect our revenues.

Currently the Russian Civil Code is undergoing the process of substantial revisions with new provisions being introduced relating to a number of spheres including basic principles of civil law, securities, property, legal entities, transactions and their invalidation, security and a number of others. At present, the potential interpretation of these amendments by state authorities (including the courts), along with their impact on our activities are unknown.

Russian companies are obliged to pay various and significant taxes including income tax, VAT, real estate tax, excise tax, payroll tax and others. Along with tax liabilities there are different obligatory

non-tax payments. These include payments into Universal Service Fund, which currently amounts to 1.2% of our annual revenue on telecommunications services. Furthermore, potential regulatory changes that may be enacted in the future, such as the introduction of new rules regulating MVNOs, new rules concerning our pricing policy and others, could weaken our competitive position in the mobile telecommunications market. Changes in tax laws and non-tax regulations may lead to the growth of our tax burden and may as a result, materially adversely affect our financial condition and results of operations.

The failure of our subsidiaries that are subject to regulations as natural monopolies to comply with the requirements of the Federal Law No. 223 "On Procurement Process", inter alia, in case of collective tendering can lead to penalties on our subsidiaries.

One of our subsidiaries, MGTS, is categorized by the Federal Tariff Service as a natural monopoly in the Moscow telecommunications market. Another our subsidiary, Comstar-regions, operating in Khanty-Mansiysk Autonomous District is also categorized as a natural monopoly in the public telecommunications market of this Region. According to the Federal Law No.223 "On Procurement Process" which came into legal force on July, 18, 2011 with recent amendments dated December 28, 2013, natural monopolies are obliged to conduct the procurement process in accordance with the principles of transparency and non-discrimination of competition. If our subsidiaries that are under additional regulations as natural monopolies are found failing to comply with the law on procurement process, inter alia in case of collective tendering with us, our subsidiaries can be subject to penalties.

Our failure to comply with new personal data protection laws and with the regulations of state authorities regarding information security in the telecommunications networks in Russia may have a material adverse effect on our business, financial condition and results of operations.

The Federal Law on Personal Data and certain regulations enacted thereunder require our information storage, processing and protection practices to be in compliance with the statutory standards, effective as of July 1, 2011. Additionally, various amendments to the current regulatory regime have been proposed by the State Duma, the Council of the Federation, the Ministry of Communications and Mass Media, the Federal Service for Supervision in the Area of Communications and Mass Media, the Federal Service for Technical and Export Control, and the Federal Security Service, in order to increase regulatory oversight over data protection.

As a result of these and other changes in personal data protection regulations, we are faced with significant technical, financial and managerial undertakings. For example, we are required to treat subscribers' personal data with the level of protection afforded to state secrets, obtain state certification of our installed information protection facilities from the Federal Service for Technical and Export Control and the Federal Security Service. We are also now directly liable for the actions of third parties to whom we forward personal data for processing. Moreover, we must now make public our data protection policies, which currently constitute a trade secret, and which may increase the risk of data protection violations if revealed. Furthermore, the modernization of our information protection systems and the optimization and reengineering of our personal data processing systems will require us to incur significant expenses. At the same time, the new regulations established by the Russian government on November 1, 2012 introduced onerous data protection requirements around data processing within the informational systems (for example, to ensure that our system and application software of foreign origin do not have any undeclared capabilities). If the resources required to develop and implement data protection systems meeting the new standards are greater than expected, or we fail to comply with the data protection laws despite our best efforts to do so, our business, financial condition and results of operations could be materially adversely affected.

Changes in Ukrainian telecommunications legislation have caused uncertainty in relation to the regulation of the Ukrainian telecommunications industry and may adversely affect our business, financial condition and results of operations.

The Ukrainian Law on Telecommunications came into force on December 23, 2003 (certain articles became effective in 2004 and 2005). The NCRC as the central regulatory body in the sphere of communications was established in August 2004.

On November 23, 2011, the NCRC was dissolved and the Ukrainian government created the NCCIR. As a result of the NCRC dissolution, the State Inspection of Communications has similarly been dissolved and there are currently no provisions in the legislation that would provide for a similar regulatory body or for its authority. The authority granted to the NCCIR is largely similar to the authority that was afforded to the NCRC.

In addition, the Ukrainian Law on Telecommunications may require, among other things, companies declared to have dominant position or SMP on the telecommunications market to develop public telecommunications services if directed to do so by the regulatory authorities. On June 24, 2010, MTS Ukraine (among other mobile operators) was found to have a dominant position on the interconnect market by the AMC. In 2012, there have been changes in legislation affecting telecommunications providers including: the Rules on Telecommunication Services making the operators responsible for the actions of content-providers, a law on state lotteries prohibiting all lotteries in Ukraine excluding those of state status and a law on telecommunications prohibiting serving new subscribers unless they provide a passport as identity confirmation.

In November 2012, NCCIR issued the statements regarding MNP, which enables the subscribers to retain their telephone number after switching from one operator of mobile communications to another. MNP law came into legal force on July, 5, 2013 with the beginning of switching to other operators from December, 20, 2013. However, on December, 30, 2013 a resolution that postponed the beginning of service provision to July, 2014 came to legal force. The approval of MNP services may lead to an increase in our costs caused by the necessity of infrastructure improvement and also lead to the intensification of competition.

Accordingly, the implementation of this law may materially adversely affect our business, financial condition and results of operations. See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Legislation."

The Russian taxation system is underdeveloped and any imposition of significant additional tax liabilities could have a material adverse effect on our business, financial condition or results of operations.

The discussion below provides general information regarding Russian taxes and is not intended to be inclusive of all issues. Investors should seek advice from their own tax advisors as to these tax matters before investing in our shares and ADSs. See also "Item 10. Additional Information—E. Taxation."

In general, taxes payable by Russian companies are substantial and numerous. These taxes include, among others, corporate income tax, value added tax, property taxes, excise duties, payroll-related taxes and other taxes.

Russian tax laws, regulations and court practice are subject to frequent change, varying interpretation and inconsistent and selective enforcement. In some instances, although it may be viewed as contrary to Russian constitutional law, the Russian tax authorities have applied certain new tax laws retroactively, issued tax claims for periods for which the statute of limitations had expired and reviewed the same tax period multiple times.

On October 12, 2006, the Plenum of the High Arbitrazh Court of the Russian Federation issued Resolution No. 53 formulating the concept of "unjustified tax benefit," which is described in the Resolution by reference to circumstances, such as absence of business purpose or transactions where the form does not match the substance, and which could lead to the disallowance of tax benefits resulting from the transaction or the recharacterization of the transaction. There has been very little further guidance on the interpretation of this concept by the tax authorities or courts, but it is likely that the tax authorities will actively seek to apply this concept when challenging tax positions taken by taxpayers in Russian courts. While the intention of this Resolution might have been to combat abuse of tax laws, in practice, there is no assurance that the tax authorities will not seek to apply this concept in a broader sense.

Generally, tax returns in Russia remain open and subject to tax audit by the tax authorities for a period of three calendar years immediately preceding the year in which the decision to conduct a tax audit is taken. The fact that a year has been reviewed by the tax authorities does not prevent further review of that year, or any tax return applicable to that year, during the eligible three-year period by a superior tax authority or, in certain limited instances, by a tax authority which conducted an initial review.

On July 14, 2005, the Constitutional Court of the Russian Federation issued a decision that allows the statute of limitations for tax penalties to be extended beyond the three-year term set forth in the tax laws if a court determines that the taxpayer has obstructed or hindered a tax audit. Additionally, according to amendments to the Tax Code of the Russian Federation, effective January 1, 2007, the three-year statute of limitations may be extended if the actions of the taxpayer created insurmountable obstacles for the tax audit. Because none of the relevant terms is defined, tax authorities may have broad discretion to argue that a taxpayer has "obstructed" or "hindered" or "created insurmountable obstacles" in respect of a tax audit and to ultimately seek review and possibly apply penalties beyond the three-year terms. According to Presidium of High Arbitrazh Court Resolution # 4134/11 of September 27, 2011, the statute of limitations for tax penalties is calculated starting from the day immediately following the expiration of the tax period when the violation was committed.

On March 17, 2009, the Constitutional Court of the Russian Federation issued a decision preventing the Russian tax authorities from carrying out a subsequent tax audit of a tax period if, following the initial audit of such tax period, a court decision was made concerning a tax dispute between the relevant taxpayer and the relevant tax authority arising out of such tax period, and such decision has not been revised or discharged. The Constitutional Court of the Russian Federation then issued Decision # 138-O-P on January 28, 2010, which confirmed the above approach. Subsequently, the Presidium of High Arbitrazh Court held in several cases that under certain circumstances (in particular, when the case has not been considered in substance) a superior tax body is still entitled to conduct a tax audit with respect to re-opened tax periods and taxes already reviewed during the initial tax audit; however, the circumstances under which the audit is conducted should differ from the initial ones (# 14585/09 of March 16, 2010, # 17099/09 of May 25, 2010, # 7278/10 of October 20, 2010).

There is no guarantee that the tax authorities will not review our compliance with applicable tax law beyond the three-year limitation period. Any such review could, if it concluded that we had significant unpaid taxes relating to such periods, have a material adverse effect on our business, financial condition, results of operations and prospects.

As of January 1, 2012, changes to the Tax Code of the Russian Federation enable Russian taxpayers which are part of a group to consolidate their financial results for profit tax purposes. It is yet unclear how the new legislative provisions will be applied by the tax authorities as currently only limited regulatory guidance is available on this matter. In addition to imposing certain criteria that must be met in order to create a consolidated tax paying group, the law also limits certain transactions

within the group (e.g. corporate restructurings). We are now considering creating a consolidated taxpaying group of taxpayers in 2015.

In addition, intercompany dividends are subject to a withholding tax of 0% or 9% (depending on whether the recipient of dividends qualifies for Russian participation exemption rules), if being distributed to Russian companies, and 15% (or lower, subject to benefits provided by relevant double tax treaties), if being distributed to foreign companies. Recent amendments to the Tax code effective from January 2014, have introduced a new increased withholding tax rate of 30% for dividends to be applied where particular information have not been provided to the custodian regarding the holders of securities held in a foreign nominee holder, foreign authorized holder or depositary program custody accounts. If the receiving company itself pays a dividend, it may offset tax withheld against its own withholding liability for the onward dividend, although not against any withholding made on a distribution to a foreign company. The above changes and potential difficulties they create related to tax reimbursement and reduced rate application may affect the investment prospects of the Russian companies.

According to the draft version of the Main Directions of Russian Tax Policy for 2013 and Planned for 2014 - 2015 and draft amendments to the Tax Code of the Russian Federation, our ability to apply accelerated tax depreciation on our equipment may be limited or excluded. It is unclear if and when such amendments will be enacted and their impact on our business, financial condition, results of operations and prospects.

The Russian tax authorities may take a more assertive position in their interpretation of the legislation and assessments, and it is possible that transactions and activities that have not been challenged in the past may nonetheless be subject to challenges in the future. The foregoing factors raise the risk of the imposition of arbitrary or onerous taxes on us, which could adversely affect the value of our shares and ADSs.

Current Russian tax legislation is, in general, based upon the formal manner in which transactions are documented, looking to form rather than substance. However, the Russian tax authorities are increasingly taking a "substance and form" approach, which may cause additional tax exposures to arise in the future. Additional tax exposures could have a material adverse effect on our business, financial condition, results of operations and prospects.

It is expected that Russian tax legislation will become more sophisticated, which may result in the introduction of additional revenue raising measures. Although it is unclear how any new measures would operate, any such introduction may affect our overall tax efficiency and may result in significant additional taxes becoming payable. Additional tax exposures could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition to the usual tax burden imposed on Russian taxpayers, these conditions complicate tax planning and related business decisions. For example, tax laws are unclear with respect to deductibility of certain expenses. This uncertainty could possibly expose us to significant fines and penalties and to enforcement measures, despite our best efforts at compliance, and could result in a greater than expected tax burden.

Based on the results of their audit in August 2012, the tax authorities of Uzbekistan assessed $669 million (RUB 21,390 million) in additional taxes, penalties and fines payable by Uzdunrobita. Afterwards all tax disputes were closed, and the total amount of damages incurred by the state was calculated on the basis of all claims against Uzdunrobita which amounted to $587 million (RUB 18,375 million). After paying two scheduled installments totaling $147.5 million (RUB 4,583.4 million) and making partial payment of the third installment amounting totaling $15.9 million (RUB 481 million) and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the

grounds of its inability to meet further obligations. As of the date of this document, we have no official documents indicating the end of liquidation procedure. However, bankruptcy proceedings in respect of 9 out of 15 branches were completed by the end of 2013. See also "—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations," and "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Tax Audits and Claims."

Russian anti-offshore policy may have adverse impact on our business, financial condition and results of operations

The President of the Russian Federation in his speech to the Federal Assembly of the Russian Federation on December 12, 2013 made certain proposals concerning deoffshorization of the Russian economy. The Russian Federation like a number of other countries in the world is actively involved in a discussion of measures against tax evasion by the use of low tax jurisdictions as well as aggressive tax planning structures. Initiatives such as the incorporation into Russian law of the concept of beneficial ownership, tax residency of legal entities, definition of offshore companies, "controlled foreign companies" rules, conclusion of multilateral agreements for exchange of information between tax authorities of different countries have already been raised by the Government in the Main Directions of Russian Tax Policy for 2014 and the planned period of 2015-2016.

The Deputy Finance Minister has declared that in the near future the Government will submit to the Russian State Duma the draft law on ratification of the multilateral Convention on Mutual Administrative Assistance in Tax Matters developed by the Council of Europe and the OECD, which the Russian Federation signed in 2011. Ratification of this Convention will enable the Russian Federation to receive tax information from all participating countries which include, among others, a number of offshore jurisdictions.

No assurance can currently be given as to whether and when the above legislative initiatives and proposals will be enacted (if at all), their exact nature, their potential interpretation by the Russian tax authorities and the possible impact on our counterparties which may be registered in off-shore jurisdictions. In case the impact of legislative initiatives is significant for some of our counterparties it may lead to potential influence on our results of operations.

The implications of the tax system in Ukraine are uncertain and various tax laws are subject to different interpretations.

Besides the new Tax Code, which came into force on January 1, 2011, Ukraine currently has a number of laws related to various taxes imposed by both central and regional authorities. Applicable taxes include value added tax ("VAT"), corporate income tax (profits tax), customs duties, payroll (social) taxes and other taxes. These tax laws have not been in force for significant periods of time compared to more developed market economies and are constantly changed and amended. Accordingly, few precedents regarding tax issues are available.

Although the Ukrainian Constitution prohibits retroactive enforcement of any newly enacted tax laws and the Law on Taxation System specifically requires legislation to adopt new tax laws at least six months prior to them becoming effective, such rules have largely been ignored. In addition, tax laws are often vaguely drafted, making it difficult for us to determine what actions are required for compliance.

Furthermore, with the entry into force of the new Tax Code of Ukraine (the "TCU"), there is uncertainty in regards to tax accounting of payments for the use of computer software. As part of its business, MTS Ukraine purchases limited end-user rights for the use of computer software. Currently, there are no clear rules for the classification of the payments made by MTS Ukraine for these purchases. Under the TCU, these payments may be treated as payments for copyrights (royalties), as

payments for intangible assets or as payments for fixed assets. Tax authorities of different levels have provided inconsistent tax clarifications on this matter. The tax rate applicable to these payments will vary according to their classification.

Also, rules established by the TCU for recalculation of the input tax credit for non-current assets are unclear. Uncertain transfer pricing rules and their inconsistent application by the Ukrainian tax authorities and courts may also adversely affect MTS Ukraine's operations. MTS Ukraine's transactions with its related parties as well as certain transactions with non-Ukrainian entities that are not MTS Ukraine's related parties may be affected by the application of the transfer pricing rules. No "safe harbor" margin is provided under Ukrainian legislation if the sale price deviates from the arm's length price.

Due to the poor quality of the applicable tax legislation and its inconsistent interpretation, it is possible that MTS Ukraine's prices could be subject to challenge and adjustment for corporate income tax or VAT purposes. Profit repatriation arrangements, such as the level of royalties for trademarks or loan interest paid by MTS Ukraine from Ukraine abroad, may also be challenged for the same reasons. If such price adjustments are implemented, MTS Ukraine's effective tax rate may increase and its financial results may be adversely affected.

Differing opinions regarding the legal interpretation of tax laws often exist both among and within governmental ministries and organizations, including the tax administration, creating uncertainties and areas of conflict for taxpayers and investors. In practice, the Ukrainian tax authorities tend to interpret tax laws in an arbitrary way that rarely favors taxpayers.

Tax declarations/returns, together with other legal compliance areas (e.g., customs and currency control matters), may be subject to review and investigation by various administrative divisions of the tax authorities, which are authorized by law to impose severe fines, penalties and interest charges. These circumstances create tax risks in Ukraine substantially more significant than typically found in countries with more developed tax systems. Generally, tax declarations/returns in Ukraine remain open and subject to inspection for a three-year period. However, this term may not be observed or may be extended under certain circumstances, including in the context of a criminal investigation.

The changes introduced into the new Tax Code of the Ukraine during 2012 created a duty to pay advance installments on tax on profits on a monthly basis and retained the duty to pay advance installments on dividend payments. Before 2013, tax on profits charged for the accounting period was reduced by the amount of advance installments made on dividend payments. In 2013 such reductions were not taken into account and we were obliged to pay the new monthly advance installment on the tax on profits as well as the advance installments on the dividend payments, which increased our tax expenses. However, following a new law issued on July, 31, 2013 it became possible to reduce the tax on profits by the amount of advance installments on dividend payments but commencing March, 1, 2014 when the 2013 tax return is filed.

On March 27, 2014, the Act on Finance Crisis Prevention was passed in Ukraine. Several provisions in the Tax Code have been changed by the act which may affect our business in Ukraine, in particular, doubling of the fees for frequency usage, and the introduction of a 0.5% tax rate applying to foreign currency purchases.

While we believe that we are currently materially in compliance with the tax laws affecting our operations in Ukraine, it is possible that relevant authorities may take differing positions with regard to interpretative issues, which may result in a material adverse effect on our results of operations and financial condition.

Vaguely drafted Russian transfer pricing rules, and lack of reliable pricing information may impact our business and results of operations.

Russian transfer pricing legislation became effective in the Russian Federation on January 1, 1999. This legislation allowed the tax authorities to make transfer pricing adjustments and impose additional tax liabilities with respect to all "controlled" transactions, provided that the transaction price differed from the market price by more than 20%. "Controlled" transactions included transactions with related parties, barter transactions, foreign trade transactions and transactions with significant price fluctuations (i.e., if the price with respect to such transactions differs from the prices on similar transactions conducted within a short period of time by more than 20%). Special transfer pricing provisions were established for operations with securities and derivatives. Russian transfer pricing rules were vaguely drafted, generally leaving wide scope for interpretation by Russian tax authorities and courts. There has been very little guidance (although some court practice is available) as to how these rules should be applied. These transfer pricing rules apply with respect to transactions that occurred before January 1, 2012.

New transfer pricing rules became effective on January 1, 2012. The implementation of these new rules should help to align domestic rules with OECD principles. The new rules are expected to considerably toughen the previously effective law by, among other things, effectively shifting the burden of proving market prices from the tax authorities to the taxpayer and obliging the taxpayer to keep in certain cases specific documentation. In addition, the amendments:

If the Russian tax authorities were to impose significant additional tax liabilities through the introduction of transfer pricing adjustments, they could have a material adverse impact on our business, financial condition and results of operations. Adoption of the new transfer pricing rules may increase the risk of transfer pricing adjustments being made by the tax authorities. In addition to the usual tax risks and tax burden imposed on Russian taxpayers, the uncertainties of the new transfer pricing rules complicate tax planning and related business decisions. It will also require us to ensure compliance with the new transfer pricing documentation requirements proposed in such rules. Uncertainty of the new rules may also require us to expend significant additional time and material resources for implementation of our internal compliance procedures. Tax authorities could impose additional tax

liability as well as penalties on the underpaid tax in case the prices or profitability are outside the market range and if the required transfer pricing documentation has not been prepared, which could have a material adverse effect on our results of operations and financial condition.

The regulatory environment for telecommunications in Russia, Ukraine and other countries where we operate or may operate in the future is uncertain and subject to political influence or manipulation, which may result in negative and arbitrary regulatory and other decisions against us on the basis of other than legal considerations and in preferential treatment for our competitors.

We operate in an uncertain regulatory environment. The legal framework with respect to the provision of telecommunications services in Russia and Ukraine and the other countries where we operate or may operate in the future is not well developed, and a number of conflicting laws, decrees and regulations apply to the telecommunications sector.

Moreover, regulation is conducted largely through the issuance of licenses and instructions, and governmental officials have a high degree of discretion. In this environment, political influence or manipulation could be used to affect regulatory, tax and other decisions against us on the basis of other than legal considerations. For example, Russian government authorities investigated Vimpelcom in late 2003 on grounds that it was illegally operating in Moscow pursuant to a license issued to its wholly owned subsidiary rather than to Vimpelcom itself. In addition, some of our competitors may receive preferential treatment from the government, potentially giving them a substantial advantage over us. For example, according to press reports, MegaFon and Kyivstar, our competitors in Russia and Ukraine, respectively, received preferential treatment in regulatory matters in the past.

An adverse change in the infrastructure regulation in Russia could result in additional costs on us.

In 2012, the Russian Ministry for Transportation proposed new rules for calculating mandatory payments for using the public easement areas of public roads where we place our communication equipment and cables. Although these rules have not been adopted to date, they provide for a calculation method which, if employed, could result in significant additional costs on us. There have been press reports that the Russian Ministry for Economic Development and Trade in its official comment disagreed with these rules implying that the rules are to be adjusted. However, it is currently unclear whether or not the original approach of the Russian Ministry for Transportation will be retained. As a result, we could be unable to successfully pass the relevant additional costs on to our customers.

In addition, starting from January 1, 2013, telecommunications operators are required to enter into agreements with owners of the roads whose public access areas host telecommunication equipment. These agreements have to contain certain provisions prescribed by the Russian Ministry for Transportation and the Russian Ministry for Economic Development and Trade. To date, no list of such provisions has been adopted. There is a risk of imbalance in the commercial interests of the operators and road owners in case such list is adopted.

Consequently, any adverse changes in legislation relating to the regulation of public roads and their interaction with telecommunications matters could have a material adverse effect on our business, financial condition, results of operations and prospects.

Government regulations may limit the ability of investors to deposit shares into our ADS facility.

The ability of investors to deposit shares into our ADS facility may be affected by current or future governmental regulations. For example, under Russian securities regulations, no more than 25% of a Russian company's shares may be circulated abroad through sponsored depositary receipt

programs. Prior to December 31, 2005, and at the time of our initial public offering, this threshold was 40%. Although we believe that the new lower threshold does not apply to our ADSs, in the future, we may be required to reduce the size of our ADS program or amend the depositary agreement for the ADSs.

Because our ADS program is regularly at or near capacity, purchasers of our shares may not be able to deposit these shares into our ADS facility, and ADS holders who withdraw the underlying shares from the facility may not be able to re-deposit their shares in the future. As a result, effective arbitrage between our ADSs and our shares may not always be possible. Our shares are listed and trade on the Moscow Interbank Currency Exchange. Due to the limited public free float of our common stock, the public market for our shares is significantly less active and liquid than for our ADSs. The cumulative effect of these factors is that our shares may from time to time, and for extended periods of time, trade at a significant discount to our ADSs.

Recent Russian legislation requires the disclosure of information about ownership of the ADSs, including in some cases beneficial ownership of the ADSs, and a failure to provide such disclosure may restrict your ability to vote.

Pursuant to recently enacted legislation, depositaries, and as a result, ADS holders, will not be able to vote in connection with the shares underlying ADSs on behalf of the ADS holders unless they provide certain information to the issuer. At a minimum, this information includes the identity of the holder of the ADSs and the number of shares attributable to each ADS holder. The exact scope of the required disclosure and procedures involved are not fully described in the new legislation, and can be further clarified in regulations to be issued by the CBR.

Moreover, even if an ADS holder chooses to provide the required information, there may be no assurance that the depositary will be successful in collecting and providing this information to the issuer on a timely basis or at all, since the process of obtaining this information is untested and could be technically complicated. In particular, the ADS ownership chains are typically multi-layered and involve, among others, global clearing systems and institutional participants in such clearing systems. Since similar data collection processes have not been widely used to date, and due to the multitude of parties involved, it is possible that technical or procedural complications will make it difficult to obtain and provide all the necessary information to the issuer on a timely basis, if at all. As a result, in case you fail to disclose your ownership or the disclosed details are not provided by the depositary to us in a timely fashion, you may be unable to vote the ADSs.

Furthermore, the legislation stipulates that the issuer, CBR, Russian courts and pretrial investigation agencies may request such lists of depositary receipt holders from the holder of depositary program depo account. The holder of depositary program depo account shall take all reasonable measures in order to provide such information. In case of non-compliance with the above requirements, the CBR may suspend, or impose limitations on, transactions with securities held in the relevant accounts of Russian custodians for a period of up to six months. As a result, the shares underlying the ADSs may be blocked and it may be impossible to deposit or withdraw the shares into or from the depositary program. Overall, there is lack of practice and official interpretation in relation to the new rules related to shares underlying ADSs as well as uncertainties with respect to exercise of certain rights attaching to shares underlying ADS holders in view of the new rules which could complicate the exercise of right to, and the ability to derive benefits from, the shares represented by ADSs.

The market price of our ADSs experienced, and may continue to experience, significant volatility. The closing price of our ADSs on the New York Stock Exchange ranged from a low of $18.60 to a high of $54.54 per ADS in 2009, a low of $17.84 to a high of $23.55 per ADS in 2010 and a low of $11.41 to

a high of $21.86 per ADS in 2011, and a low of $15.69 to a high of $20.07 per ADS in 2012, in 2013, a low of $17.78 per ADS to a high of $23.78 per ADS. On May 3, 2010, the ADS to ordinary share ratio was changed from five ordinary share for one ADS to two ordinary shares for one ADS.

Numerous factors, including many over which we have no control, may have a significant impact on the market price of our ADSs, including, among other things:

In addition, the stock market in recent years has experienced extreme price and trading volume fluctuations that often have been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations may adversely affect the price of our ADSs, regardless of our operating performance.

Voting rights with respect to the shares represented by our ADSs are limited by the terms of the deposit agreement for our ADSs and relevant requirements of Russian law.

ADS holders will have no direct voting rights with respect to the shares represented by the ADSs. They will be able to exercise voting rights with respect to the shares represented by ADSs only in accordance with the provisions of the deposit agreement relating to the ADSs and relevant requirements of Russian law. Therefore, there are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional procedural steps involved in communicating with them. For example, the Joint Stock Companies Law and our charter require us to notify shareholders no less than 30 days prior to the date of any meeting and at least 70 days prior to the date of an extraordinary meeting to elect our Board of Directors. Our ordinary shareholders will receive notice directly from us and will be able to exercise their voting rights by either attending the meeting in person or voting by power of attorney.

ADS holders by comparison, will not receive notice directly from us. Rather, in accordance with the deposit agreement, we will provide the notice to the depositary. The depositary has undertaken, in turn, as soon as practicable thereafter, to mail to you the notice of such meeting, voting instruction forms and a statement as to the manner in which instructions may be given by ADS holders. To exercise their voting rights, ADS holders must then instruct the depositary how to vote the shares represented by the ADSs they hold. Because of this additional procedural step involving the depositary, the process for exercising voting rights may take longer for ADS holders than for holders of the shares and we cannot assure ADS holders that they will receive voting materials in time to enable them to

return voting instructions to the depositary in a timely manner. ADSs for which the depositary does not receive timely voting instructions will not be voted. We cannot provide any assurance that holders and beneficial owners of ADSs will (i) receive notice of shareholder meetings to enable the timely return of voting instructions to the depositary, (ii) receive notice to enable the timely cancellation of ADSs in respect of shareholder actions or (iii) be given the benefit of dissenting or minority shareholders' rights in respect of an event or action in which the holder or beneficial owner has voted against, abstained from voting or not given voting instructions.

Amendments to the Federal Law on Securities Market provide for new restrictions in relation to voting of shares represented by ADSs. See also "—Recent Russian legislation requires the disclosure of information about ownership of the ADSs, including in some cases beneficial ownership of the ADSs, and a failure to provide such disclosure may restrict your ability to vote."

ADS holders may be unable to repatriate distributions made on the shares and ADSs.

We anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of ADSs, net of the depositary's fees and expenses. The ability to convert rubles into U.S. dollars is subject to the availability of U.S. dollars in Russia's currency markets. Although there is an existing, albeit limited by size, market within Russia for the conversion of rubles into U.S. dollars, including the interbank currency exchange and over-the-counter and currency futures markets, the further development of this market is uncertain. At present, there is a limited market for the conversion of rubles into foreign currencies outside of Russia and limited market in which to hedge ruble and ruble-denominated investments.

Prior to the amendments to the Russian securities laws introduced in 2011, a depositary bank could be considered the owner of the shares underlying the ADS, and as such could be subject to the mandatory public tender offer rules, anti-monopoly clearance rules, governmental consents or reporting requirements in respect of acquisition of shares and other limitations contemplated by Russian law. The amendments to the Russian securities laws introduced in 2011 provide that a depositary bank is not an owner of underlying shares, and as such, these requirements should apply to ADS holders.

ADS holders may be unable to benefit from the United States—Russia income tax treaty.

Under Russian law, dividends paid to a non-resident holder of the shares generally will be subject to Russian withholding tax at a rate of 15%. This tax may potentially be reduced to 5% or 10% for legal entities and organizations and to 10% for individuals under the Convention between the United States of America and the Russian Federation for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income and Capital (the "United States—Russia income tax treaty") provided a number of conditions are satisfied. However, the Russian tax rules on the application of double tax treaty benefits to individuals are unclear and there is no certainty that advance clearance would be possible. Furthermore, recent amendments to the Tax Code have introduced new rules in relation to dividend payment to holders of ADSs which establish certain requirements to the information to be provided to the custodian acting as the tax agent in order for him to be able to utilize the basic 15% or a reduced 10% withholding tax rate. In the absence of such information the custodian is required to use an increased 30% withholding tax rate. Such information includes at a minimum information regarding the number of securities held in a specific tax jurisdiction. The amendments also provide for a simplified tax refund process with the tax agent available to ADS holders where an increased level of tax was withheld. However, the process of collection of such information and its transfer from the depositary to the custodian as well as the process of the expedited refund are not tested at this point and it is not clear how they will work in practice. In addition to that

the same amendments have restricted the possibility of using the 5% reduced rate under the United States—Russia income tax treaty for advance withholding which make it possible to utilise it only by way of later reimbursement with the Russian tax authorities. Further to the above we note that the custodian may be obliged to withhold tax at standard non-treaty rates or at a higher rate when paying out dividends, and U.S. ADS holders may be unable to benefit from the United States—Russia income tax treaty. See also "Item 10. Additional Information—E. Taxation" for additional information.

Capital gain from the sale of shares and ADSs may be subject to Russian income tax.

Under Russian tax legislation, gains realized by non-resident legal entities or organizations from the disposition of shares and securities of Russian organizations, as well as financial instruments derived from such shares, such as the ADSs, may be subject to Russian withholding income tax if immovable property located in Russia constitutes more than 50% of our assets. However, no procedural mechanism currently exists to withhold and remit this tax with respect to sales made to persons other than Russian companies and foreign companies with a registered permanent establishment in Russia. Gains arising from the disposition of the foregoing types of securities on foreign stock exchanges by non-resident holders who are legal entities or organizations are not subject to taxation in Russia.

The taxation of income of non-resident individuals depends on whether this income is received from Russian or non-Russian sources. Russian tax law does not give a definition of how the "source of income" should be determined with respect to the sale of securities, other than that income from the sale of securities "in Russia" should be considered as Russian source income. As there is no further definition of what should be considered to be a sale "in Russia," the Russian tax authorities have a certain amount of freedom to conclude what transactions take place in or outside Russia, including looking at the place of the transaction, the place of the issuer of the shares or other similar criteria.

Non-residents who are individuals are taxable on Russian-source income. Provided that gains arising from the disposition of the foregoing types of securities and derivatives outside of Russia by U.S. holders who are individuals not resident in Russia for tax purposes will not be considered Russian source income, then such income should not be taxable in Russia. However, gains arising from the disposition of the same securities and derivatives "in Russia" by U.S. holders who are individuals not resident in Russia for tax purposes may be subject to tax either at the source in Russia or based on an annual tax return, which they may be required to submit with the Russian tax authorities. See also "Item 10. Additional Information—E. Taxation."

The lack of a developed practice relating to share registration system in Russia and other countries where we operate may result in improper record ownership of our shares, including the shares underlying the ADSs, and other problems connected with the rights attributed to the relevant shares such as dividend payments.

Ownership of Russian joint stock company shares (or, if the shares are held through a nominee or custodian, then the holding of such nominee or custodian) is determined by entries in a share register and is evidenced by extracts from that register. Currently, the central registration system in Russia is under development. Share registers are maintained by the companies themselves or, if a company has more than 50 shareholders or so elects, by licensed registrars. Regulations have been issued regarding the licensing conditions for such registrars, as well as the procedures to be followed by both companies maintaining their own registers and licensed registrars when performing the functions of registrar. In practice, however registrars generally have relatively low levels of capitalization and inadequate insurance coverage.

On December 7, 2011 amendments to the relevant legislation were adopted, substantially reforming the registration system by introducing the CSD. In the course of this reform of the share keeping system, numerous different depositaries with accounts in the registers of companies are

expected to be replaced by a single central depositary, whose primary function would be the custody of shares in all major companies. These changes became effective on January 1, 2012 and are currently being implemented. On November 6, 2012, FSFM officially appointed the National Settlement Depositary as the central depositary. Since the central depositary opened its account in MTS register in March 2013, all the other custodians are restricted from opening their accounts in the register. Currently the central depositary is the only custodian with an account in MTS' register and other custodians hold custodial accounts with the central depositary.

In addition, certain amendments to the Civil Code entered into force on October 1, 2013 regarding the transfer and restitution of securities that are aimed at protection of rights of security holders.

It is however unclear how these new provisions will be applied and during the initial stage of development of a central share registration system in Russia, transactions in respect of a company's shares could be improperly or inaccurately recorded, and share registration could be lost through fraud, negligence, official and unofficial governmental actions or oversight by registrars incapable of compensating shareholders for their misconduct. This creates risks of loss not normally associated with investments in other securities markets. Further, the depositary, under the terms of the deposit agreement, will not be liable for the unavailability of our shares or for the failure to make any distribution of cash or property with respect thereto due to the unavailability of the shares.

In addition on July 6, 2012 a central depositary was introduced in Ukraine. Such central depositary is to hold the shares of all joint stock companies in Ukraine. The methods of dividend payments was also changed: according to the new rules the joint-stock company transfers dividends to the CSD through the operating account at the special processing center in order to enable the central depositary make the onward transfer to the parties eligible to receive dividends. The changes came into force on October 12, 2013 and could affect the timing of dividend payouts.

Our presence outside the United States may limit your legal recourse against us. We are incorporated under the laws of the Russian Federation. Substantially all of our directors and executive officers named in this document reside outside the United States. All or a substantial portion of our assets and the assets of our officers and directors are located outside the United States. As a result, you may not be able to effect service of process within the United States on us or on our officers and directors. Similarly, you may not be able to obtain or enforce U.S. court judgments against us, our officers and directors, including actions based on the civil liability provisions of the U.S. securities laws. In addition, it may be difficult for you to enforce, in original actions brought in courts in jurisdictions outside the United States, liabilities predicated upon U.S. securities laws.

There is no treaty between the United States and the Russian Federation providing for reciprocal recognition and enforcement of foreign court judgments in civil and commercial matters. These limitations may deprive you of effective legal recourse for claims related to your investment in our shares and ADSs. The deposit agreement provides for actions brought by any party thereto against us to be settled by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association, provided that any action under the U.S. federal securities laws or the rules or regulations promulgated thereunder may, but need not, be submitted to arbitration. The Russian Federation is a party to the United Nations (New York) Convention on the Recognition and Enforcement of Foreign Arbitral Awards, but it may be difficult to enforce arbitral awards in the Russian Federation due to a number of factors, including the inexperience of Russian courts in international commercial transactions, official and unofficial political resistance to enforcement of

awards against Russian companies in favor of foreign investors and Russian courts' inability to enforce such orders and corruption.

We have not independently verified information we have sourced from third parties.

We have sourced certain information contained in this document from third parties, including private companies and Russian government agencies, and we have relied on the accuracy of this information without independent verification. The official data published by Russian federal, regional and local governments may be substantially less complete or researched than those of more developed countries. Official statistics may also be produced on different bases than those used in Western countries. Any discussion of matters relating to Russia in this document must, therefore, be subject to uncertainty due to concerns about the completeness or reliability of available official and public information. In addition, the veracity of some official data released by the Russian government may be questionable. In 1998, the Director of the Russian State Committee on Statistics and a number of his subordinates were arrested and subsequently sentenced by a court in 2004 in connection with their misuse of economic data.

Because no standard definition of a subscriber, average monthly service revenue per user ("ARPU"), average monthly usage per user ("MOU") or churn exists in the telecommunications industry, comparisons between certain operating data of different companies may be difficult to draw.

The methodology for calculating subscriber numbers, ARPU, MOU and churn varies substantially in the telecommunications industry, resulting in variances in reported numbers from that which would result from the use of a uniform methodology. Therefore, comparisons of certain operating data between different telecommunications companies may be difficult to draw.

Mobile TeleSystems CJSC ("MTS CJSC") our predecessor, was formed in 1993. The founding shareholders included MGTS and three other Russian telecommunications companies, which collectively held 53% of our original share capital, and two German companies, Siemens AG and T-Mobile Deutschland GmbH, an affiliate of Deutsche Telekom AG, which collectively held the remaining 47%. Sistema currently owns 51.46% of our share capital (53.46% excluding treasury shares). See "Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders."

Our legal name is Mobile TeleSystems OJSC, and we are incorporated under the laws of the Russian Federation. Our head office is located at 5 Vorontsovskaya Street, Bldg. 2, Moscow 109147, Russian Federation, and the telephone number of our investor relations department is +7 495 223-2025. The address of our incorporation is 4 Marksistskaya Street, Moscow 109147, Russian Federation. We maintain a website at www.mtsgsm.com. The information on our website is not a part of this report. We have appointed Puglisi & Associates, 850 Library Avenue, Suite 204, Newark, Delaware 19715 as our authorized agent for service of process for any suit or proceeding arising out of or relating to our shares, ADSs or the deposit agreement.

Mobile TeleSystems OJSC was created on March 1, 2000, through the merger of MTS CJSC and RTC CJSC, a wholly owned subsidiary. Our charter was registered with the State Registration Chamber on March 1, 2000, which is our date of incorporation, and with the Moscow Registration Chamber on March 22, 2000. Our initial share issuance was registered by the Russian Federal Commission on the Securities Market on April 28, 2000.

We completed our initial public offering on July 6, 2000, and listed our shares of common stock, represented by ADSs on the New York Stock Exchange (the "NYSE") under the symbol "MBT." Each ADS represents two underlying shares of our common stock. Prior to May 3, 2010, each ADS represented five shares of our common stock.

In September 2001, we won a tender held by the Telecommunications Ministry of the Belarus Republic to form a joint venture with a GSM 900/1800 license to operate in Belarus. On June 26, 2002, MTS Belarus received all of the governmental approvals and licenses required to commence operations in Belarus and it began operations on June 27, 2002. In 2003 through a number of purchases we acquired a 100% stake in MTS Ukraine for RUB 11,872 million. Since July 2007, we have operated under the MTS brand in Ukraine.

In August 2004, we acquired a 74% stake in Uzdunrobita, the largest wireless operator in Uzbekistan, for $126.4 million (RUB 3,693 million) in cash. We acquired the remaining 26% stake in June 2007 pursuant to a put option agreement for $250.0 million (RUB 6,481 million) in cash. In May 2006, we started operations under the MTS brand in Uzbekistan. In July 2012, we suspended providing services in Uzbekistan per the order from the State Agency for Communications and Information ("SACI") of Uzbekistan on the temporary suspension of the operating license of Uzdunrobita for a period of 10 business days which was subsequently extended to three months. On August 13, 2012, the Tashkent Economic Court granted the petition of the SACI to withdraw all operating licenses of Uzdunrobita. Simultaneously various Uzbek government agencies claimed multiple violations by Uzdunrobita, which having passed through numerous court hearings resulted in heavy penalties which Uzdunrobita has been unable to satisfy. Uzdunrobita has submitted its application initiating self-bankruptcy procedures to relevant Uzbek court. On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated six month liquidation procedures, which we understand to be still in place following several extensions. As a result, we lost control over the subsidiary and deconsolidated Uzdunrobita. We are procuring efforts to resolve the dispute under international laws. Please see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" regarding recent suspension of our services in Uzbekistan and "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Uzbekistan."

In two separate purchases in June and November 2005, we acquired 100% of BCTI, the leading wireless operator in Turkmenistan, for $46.7 million (RUB 1,343 million) in cash. Since October 2006, we have operated under the MTS brand in Turkmenistan. On December 21, 2010, the Ministry of Communication of Turkmenistan suspended our primary operating license and we ceased providing mobile telecommunications services in Turkmenistan. In August 2012, we restarted our mobile communication operations in Turkmenistan and resumed providing services for subscribers who did not cancel their contracts. Since October 1, 2012, we resumed our operations in Turkmenistan entirely and started entering into contracts with new subscribers. See "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations."

In September 2007, we acquired an 80% stake in International Cell Holding Ltd., a 100% indirect owner of K-Telecom, the leading wireless operator in Armenia, for €260.0 million (RUB 9,142 million), and entered into a call and put option agreement initially valid until 2012 (and later extended until 2016) for the remaining 20%. K-Telecom operates in the GSM-900/1800 standard, covering the entire territory of Armenia. It historically operated under the VivaCell brand, and was re-branded as VivaCell-MTS in September 2008.

In October 2009, we acquired a 50.91% stake in Comstar, a leading fixed line operator in Russia, from Sistema, and subsequently increased our ownership interest to 61.97% (or 64.03% excluding treasury shares) in December 2009 and to 70.97% (or 73.33% excluding treasury shares) in September 2010 through a voluntary tender offer. On December 23, 2010, the extraordinary general meetings of shareholders of Comstar and MTS approved a merger of Comstar and MTS, which was completed on April 1, 2011. As a result, Comstar ceased to exist as a separate legal entity and MTS became the legal successor of Comstar in respect of all its rights and obligations.

Prior to April 1, 2011, Comstar operated in both the alternative and traditional fixed line communications markets, offering voice telephony, broadband Internet and pay-TV, operator interconnect and other services to its subscribers. After April 1, 2011, we continued, and still continue to provide these services. Among our subsidiaries is MGTS, Moscow's incumbent fixed line operator with "last mile" access (the final phase of delivering connectivity from a communications provider to a customer) to approximately 96% of the households in Moscow.

In 2011, we completed the re-branding of Comstar with our main MTS brand. MGTS, a former subsidiary of Comstar, continues to provide services under its own brand.

In 2009, we started to develop our sales and distribution network both organically and through the acquisition of several national and regional retail chains. We organized our retail operations under a wholly owned subsidiary, Russian Telephone Company ("RTC"). RTC handles all functions relating to our retail operations, including the management of points-of-sale, the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets.

In 2010, 2011 and 2012 we acquired controlling stakes in various regional fixed line operators as we are determined to develop broadband Internet through regional expansion.

In April 2013, MTS, through its wholly-owned subsidiary, acquired a 25.095% stake in MTS Bank for 5.09 billion rubles ($163.5 million as of April 3, 2013) through an additional share issuance by the bank. The transaction was concluded in accordance with the terms of an indicative offer between MTS, MTS Bank and Sistema. MTS and MTS Bank have also concluded a profit-sharing agreement pursuant to which MTS and MTS Bank would realize 70% and 30% of the proceeds from the MTS Dengi (MTS Money) project, respectively. The MTS Dengi project was recently launched by MTS and MTS Bank and is aimed at providing customers throughout Russia with a variety of payment tools, including credit cards, near-field communications-enabled SIM cards and PoS (point-of-sale) credit.

We spent in total RUB 81,575 million in 2013 for network development in Russia and the other countries where we operate, which included RUB 67,146 million in cash expenditures on property, plant and equipment, and RUB 14,429 million for the purchase of intangible assets. We expect to spend approximately RUB 90 billion in 2014 for the on-going roll out of Long-Term Evolution ("LTE") networks throughout Russia and enhancements to 3G networks, continued deployment of our Gigabit Passive Optical Network ("GPON") in Moscow and Moscow Region, network improvements and equipment swaps in Ukraine, maintenance capital expenditures in Armenia and build out of 3G networks in Turkmenistan. We plan to finance our capital expenditures primarily through operating cash flows, and to the extent necessary, through additional external financing. The actual amount of our capital expenditures for 2014 may vary depending on subscriber growth, demand and network development, as well as currency volatility, vendor terms and the availability of external financing. The capital expenditure estimate for 2014 excludes expenditures that may be made in connection with acquisitions or new licenses. A breakdown of our capital expenditures in 2013 by country is set forth below. For the first quarter of 2014 and continuing into the second quarter, our principal capital expenditures have related and continue to relate to the build-out of our network and GPON project which we have financed through operating cash flows.

We spent RUB 6,569 million, RUB 1,937 million and nil in 2011, 2012 and 2013, respectively, for acquisitions of subsidiaries, net of cash acquired.

On December 23, 2010, an extraordinary general meeting of the MTS' shareholders approved the merger of Comstar-UTS into MTS. We redeemed Comstar-UTS shares held and put by non-controlling interest shareholders within the limit set forth by Russian law at a specified price. The consideration paid to Comstar-UTS shareholders in the first quarter of 2011 totaled RUB 4,786 million.

In December 2011, we acquired 29% of the ordinary shares of MGTS from Sistema for RUB 10.6 billion. In addition, we assumed debt in the amount of RUB 10.4 billion due and payable by the end of 2011. See also "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Acquisitions" and Note 3 to our audited consolidated financial statements.

We spent RUB 70,910 million in 2013 for network development in Russia, including RUB 58,226 million in cash expenditures on property, plant and equipment, and RUB 12,684 million for the purchase of intangible assets.

We spent RUB 8,840 million in 2013 for network development in Ukraine, including RUB 7,281 million in cash expenditures on property, plant and equipment, and RUB 1,559 million for the purchase of intangible assets.

We spent RUB 732 million in 2013 for network development in Turkmenistan, including RUB 731 million in cash expenditures on property, plant and equipment, and RUB 1 million for the purchase of intangible assets.

We spent RUB 1,092 million in 2013 for network development in Armenia, including RUB 907 million in cash expenditures on property, plant and equipment, and RUB 185 million for the purchase of intangible assets.

MTS Belarus spent RUB 2,350 million in 2013 for network development, including RUB 1,525 million in cash expenditures on property, plant and equipment, and RUB 825 million for the purchase of intangible assets. We do not include the capital expenditures of MTS Belarus in our capital expenditures described above as its results are not consolidated in our financial statements.

We are a leading telecommunications provider in Russia and the CIS, providing a wide range of mobile and fixed line voice and data telecommunications services, including data transfer, broadband, pay-TV and various value-added services, as well as selling equipment and accessories. According to AC&M-Consulting, we are the largest provider of mobile cellular communications services in Russia and Armenia and the second largest in Ukraine in terms of mobile subscribers.

As of December 31, 2013, we had a mobile subscriber base of approximately 102.4 million (approximately 75.3 million in Russia, 22.7 million in Ukraine, 2.4 million in Armenia, and 2.0 million

in Turkmenistan), which is an increase of 6,89% compared to December 31, 2012. We are also the largest operator in the Moscow residential broadband market in terms of subscribers, with a 27% market share as of December 31, 2013, according to Direct INFO. Our revenues for the year ended December 31, 2013, were RUB 398,443 million, an increase of 5.3% from the year ended December 31, 2012. Our net income for the year ended December 31, 2013, was RUB 79,839 million, an increase of 169% from the year ended December 31, 2012.

Russia is our principal market, both in terms of subscribers and revenues. For each of the three years ended December 31, 2013, 2012 and 2011, approximately 89% of our revenues came from operations in Russia; approximately 10% of our revenues came from operations in Ukraine; and approximately 1% of our revenues came from operations in other countries, respectively.

As of December 31, 2013, approximately 74% of our mobile subscriber base was in Russia and approximately 22% was in Ukraine. According to AC&M-Consulting, as of December 31, 2013, we had a 31.% and 37% market share of total mobile subscribers in Russia and Ukraine, respectively.

The table below sets forth our total mobile subscribers as of the end of the last five years:

In 2012 we ceased to provide mobile cellular communications services in Uzbekistan as all operating licenses of our subsidiary, Uzdunrobita, were withdrawn by the State Agency for Communications and Information of Uzbekistan on August 13, 2012. See "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of our subsidiaries in the coutries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations."

In Turkmenistan, our primary operating license was suspended on December 21, 2010, and we ceased providing mobile telecommunications services in that country for two years. In 2012, our operating license and as a result our operations in Turkmenistan were resumed. Our subscriber base amounted to approximately 2.02 million subscribers as of December 31, 2013. For more information, see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations."

According to AC&M-Consulting, overall mobile cellular penetration in Russia was approximately 170.0% as of December 31, 2013, which is an increase from 161.3% at December 31, 2012. Mobile cellular penetration in Ukraine was approximately 133.1% as of December 31, 2013, which is an increase from 126.1% as of December 31, 2012. According to our estimates, mobile cellular penetration in Armenia was approximately 117.3% as of December 31, 2013, as compared to approximately 118.8% as of December 31, 2012. Mobile penetration in Turkmenistan was approximately 105.4% as of December 31, 2013, which is an increase from 85.9% as of December 31, 2012, according to our estimates.

Our consolidated mobile subscriber base increased insignificantly in the first two months of 2014. Specifically, according to our estimates at March 1, 2014, we had approximately 103.2 million subscribers, including approximately 75.9 million in Russia, 22.9 million in Ukraine, 2.4 million in Armenia and 2.0 million in Turkmenistan.

As of December 31, 2013, we had mobile licenses to operate and commercial mobile operations throughout the entire territory of Russia with a population of approximately 143 million people, throughout the entire territory of Ukraine with a population of approximately 45 million people, throughout the entire territory of Turkmenistan with a population of approximately 5 million people and throughout the entire territory of Armenia with a population of approximately 3 million people. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Failure to renew our licenses or receive renewed or new licenses with similar terms to our existing licenses could have a material adverse effect on our business and results of operations," and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Failure to fulfill the terms of our licenses could result in their suspension or termination, which could have a material adverse effect on our business and results of operations."

MTS Belarus had approximately 5.39 million subscribers and a leading market share of 46.7% at December 31, 2013, according to our estimates. At December 31, 2012, according to our estimates, MTS Belarus had approximately 5.23 million subscribers and a leading market share of 46.9%. Belarus, a country with a population of approximately 9.5 million, had a mobile cellular penetration rate of approximately 122% at December 31, 2013, according to our estimates.

In 2011, 2012 and 2013, we significantly expanded our operations in an effort to meet the challenges of our evolving markets and further the goals of our strategy set out in more detail below. Through our acquisition of a controlling stake in Comstar in October 2009, we have become a leading fixed line services provider in Russia.

We have also continued to develop our proprietary sales and distribution network organically.

To maintain and increase our market share and brand awareness, we use a combination of print media, radio, television, direct mail and outdoor advertising, focusing on brand and image advertising, as well as promotion of particular tariff plans.

Our key strategic goal is leadership in all markets of presence, delivering the best-in-the-market telecommunication experience to our subscribers, including high-speed Internet access at home and on the go, cable TV entertainment with access to best content portfolio and top quality mobile and fixed voice services. We are at the forefront of LTE development in Russia and CIS and we are focused on building the fastest and most reliable 4G wireless networks and providing the best service to our customers by bringing access to the connected world.

In order to achieve our goals in 2014 we are executing on our new "3D" strategy. Our new strategy envisions three areas of focus: Data, Differentiation, Dividends, and as described below, is a key to sustaining our leadership positions. The "3D" strategy expands and develops our strategic priorities and principles that we formulated in 2013.

Implementation of the strategy is subject to a number of risks. See "Item 3. Key Information—D. Risk Factors" for a description of these and other risks we face.

We are a provider of wireless and fixed line communications services in Russia, Ukraine, Armenia and Turkmenistan. Prior to withdrawal of all operating licenses of Uzdunrobita on August 13, 2012, by the State Agency for Communications and Information of Uzbekistan, we also provided mobile cellular communications services on the entire territory of Uzbekistan. See "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations."

For a list of our major subsidiaries and our ownership percentages in these subsidiaries, see "Item 4. Information on our Company—C. Organizational Structure."

We primarily offer mobile cellular voice and data communication services to our subscribers on the basis of various tariff plans designed for different market segments. In general, most of our tariff plans combine per minute usage charges, value-added services and, in some cases, monthly network access fees. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Tariffs."

Roaming allows our customers, both subscribers and guest roamers, to receive and make international, local and long-distance calls while traveling outside of their home network. Roaming is provided through individual agreements between us and other GSM operators. Unlike many non-GSM providers that require additional equipment or prior notification, our roaming service is instantaneous, automatic and requires no additional equipment.

As of December 31, 2013, we had bilateral roaming contracts with 751 wireless operators in 227 countries, including 13 regional operators in Russia. We continually seek to expand our roaming capability and are currently in negotiations with additional operators.

We offer various value-added services to our customers. These services may be included in the tariff plan selected by the subscriber or subscribers may pay additional monthly charges and, in some cases, usage charges for them. Some basic value-added services that we offer include:

We offer GPRS services, enabling our subscribers to access the Internet, WAP and MMS in all of the countries where we operate. We also provide international data transfer roaming to our subscribers, enabling them to use various GPRS/3G based services while traveling abroad.

We also offer the MTS-Connect service, which allows our subscribers to get mobile Internet access through a GPRS/EDGE/3G/LTE/HSDPA/HSPA ("High Speed Packet Access") connection, using a

computer, PC-card and USB-modem. This service is available to our subscribers in Russia and Ukraine and in more than 217 countries where we have GPRS roaming.

In April 2007, the Russian Ministry of Communications and Mass Media announced the results of a tender for 3G licenses. We were one of three companies, along with Vimpelcom and MegaFon, who received a nationwide 3G/UMTS (Universal Mobile Telecommunications System) license in Russia. The license is valid through 2017 and covers the entire territory of Russia. In accordance with the conditions set forth in the tender documentation, we, Vimpelcom and MegaFon were required to begin undertaking the construction of a 3G network over a period of two years from the time the license was received. We currently have commercial 3G networks launched in all regions of Russia.

By the end of 2013, we installed 31,561 3G base stations throughout Russia. Together with 3G networks in Belarus, Turkmenistan and Armenia, we operate 35,507 3G base stations. We have also obtained a permit to use the UMTS 900 standard in Moscow Region and Habarovskiy kray. As of December 31, 2013, our UMTS 900 network consisted of 1162 base stations.

In 2010, we began to implement an upgraded version of the HSPA technology known as HSPA+. This technology allows us to provide our subscribers with faster data transmission speeds. We have launched HSPA+ technology which supports up to 21 Mbit per second data transmission speed. We have launched second and third WCDMA frequencies for capacity purposes and activated Dual Carrier technology which supports up to 42 Mbit per second data transmission speed in 15,693 UMTS sites in Russia.

In 2011, we began to develop a 3G femtocell network. Femtocells are small low-power wireless base stations in the licensed 2100 MHz spectrum. They connect to a mobile operator's network using residential DSL or cable broadband connections and can support multiple standard mobile devices. Femtocells deliver a strong signal and high-quality voice service to standard mobile devices in homes, small and large offices, outdoor public spaces, metro hotspots and rural areas. They allow for strong signal performance even in areas where MTS cellular coverage is limited or unavailable. A femtocell network also provides for high speed of data upload and download. The total number of femtocells installed in Russia reached 2,250 by the end of 2013.

In July 2006, MTS Ukraine was licensed to provide telecommunications services using CDMA 450 technology. CDMA 450 is a 3G telecommunication standard ratified by the International Telecommunication Union. We commenced commercial services using CDMA 450 technology in Ukraine in November 2007. In July 2012, we launched Rev B CDMA technology services in the Kiev Region and currently offer high-speed mobile Internet access to our subscribers throughout Ukraine.

In October 2007, K-Telecom, our subsidiary in Armenia was allocated frequencies to offer 3G services throughout the entire territory of Armenia. The frequencies were allocated for a 10-year period. In 2009, we commercially launched our 3G network in Armenia. In 2010, we further expanded our 3G network to cover all towns and villages with a population of more than 2,000 people, and, as a result, 98% of inhabited areas are covered with our 3G outdoor services. In 2011, K-Telecom started to provide telecommunications services based on HSPA+ technology in Yerevan, six northern regions and in some southern regions of the country. We plan to extend HSPA+ technology to all regions of the country by the end of the next year. In 2012, we completed the replacement of outdated 2G radio equipment with SingleRAN technology. We are currently implementing an all-IP concept by providing IP interfaces and transmission link for all base station sites, which is the basic approach for future LTE networks.

In Turkmenistan, we currently provide services based on 3G technology in Ashgabat only. 3G services are available only to our corporate clients due to limited external Internet channel bandwidth

which we lease from the state-controlled telecoms provider. HSPA+ (MIMO) and DC-HSPA services are also available in our 3G network.

In 2013, we started replacing outdated radio access network with SingleRAN technology, while providing IP interfaces and transmission links. In 2014, we plan to significantly expand our 3G network in Turkmenistan launching 3G services in all major cities of the country.

In July 2012, the Russian Ministry of Communications and Mass Media announced the results of a tender for national-wide LTE-FDD frequencies. MTS is among the four companies, including Rostelecom, MegaFon, and Vimpelcom which obtained LTE-FDD frequencies in 700, 800 and 2600 MHz bands.

In August 2012 we launched LTE services in Kazan based on the MVNO business strategy. In September, 2012 we began offering LTE-based commercial services in Moscow Region where we initially rolled out more than 800 LTE TDD eNodeB's. In December 2013, we had 2002 LTE TDD and the 1231 LTE FDD base stations in Moscow. As of December 31, 2013, we have LTE network in 17 regions of Russia with 5023 eNodeB's in total.

In Yerevan, the capital of Armenia, we commenced a commercial test of the first 4G/LTE network in December 2010. In 2013, we provided full LTE outdoor coverage for two major cities—Gyumri and Vanadzor, LTE coverage in Yerevan was also considerably expanded. Circuit Switch Fall Back (CSFB) functionality is available to all our LTE subscribers.

In addition to cellular communication services, we offer corporate clients a number of telecommunications services such as design, construction and installation of local voice and data networks capable of interconnecting with fixed line operators, installation and maintenance of cellular payphones, lease of digital communication channels, access to open computer databases and data networks, including the Internet, and provision of fixed, local and long-distance telecommunications services, as well as video conferencing.

In October 2008, we announced a strategic agreement with Vodafone aimed at drawing on Vodafone's expertise in building and developing 3G networks and mobile broadband products, working with leading global equipment providers and deploying innovative client relationship management ("CRM") practices to enhance quality and further improve the efficiency of our operations. In addition, the agreement allows us exclusive access to a range of products, services and devices from Vodafone for our markets of operation in Russia, Ukraine, Turkmenistan and Armenia.

Our target customers historically included companies, professionals, high-income individuals, reporters, government organizations, businesspersons and diplomats. However, with mobile cellular penetration in these segments becoming saturated, we began to more aggressively promote our mobile cellular services to a much wider group of the population. Over time, we adjusted our service model to provide differentiated levels of service to meet the needs of distinctive customer segments as such segments have developed. Today, we are considered a mass-market mobile network operator with a wide range of subscribers in all customer segments. As part of our business, we provide a wide range of products and services to these customer segments.

In 2013, we concentrated our marketing initiatives on the strategic development of mobile internet services and extensive growth of the mobile broadband user base. This will also remain our focus in 2014 as we shift our strategy to become more than a mobile operator in the traditional sense of the word and rather an internet and total telecom service provider company of the new economy. The goal of these marketing initiatives is to establish us as the best value operator and the most attractive data services provider in the Russian market.

These key focuses are in line with growing global market trend of transitioning from voice-centered services to data-driven business models. In 2013, we put greater emphasis on attracting new mobile internet users who had not previously used mobile broadband. This mass audience significantly drove our data revenues in 2013.

The key theme for our advertising campaigns in 2013 was the education of users on how mobile internet can help them in everyday life. Our 2013 communication strategy also included the use of a number of top-tier celebrities to ensure the highest possible influence on our audience.

In order to build brand awareness and stimulate demand we currently use a combination of various advertising formats, including television, outdoor, newspaper, magazine and radio. Increasingly we also advertise on-line (with the help of traditional as well as innovative and novel projects) to market and promote our products and services to the broad audiences of current and potential customers. Additionally, our indirect advertising includes sponsorship of selected television programs, sport events, music shows and other popular events. We also coordinate the advertising policies of our dealers and partners, such as MTS Bank, to capitalize on the increased volume of joint advertising and preserve the integrity and high-quality image of the MTS brand. For example, in 2012, we developed a creative framework and visual style for MTS Bank which has been used by MTS Bank in all of its communications since March 2012. In addition, we focus our advertising and marketing efforts on emphasizing the affordability and variety of our tariff plans, the broad coverage of our network and the use and availability of national roaming.

In 2013, we concentrated our efforts on strengthening our positioning as data services provider and operator. As a result the major part of our marketing activities in both products and services areas was closely connected with this strategic focus.

To support our key directions we undertook the following initiatives in 2013 in Russia and in selected other countries in which we operate:

In December 2008, we reached an agreement with Sistema Shyam TeleServices Limited ("SSTL") allowing SSTL to use the MTS brand in India. Sistema is the majority shareholder of SSTL with an ownership stake of 56.68%. Under the terms of the agreement, SSTL has had the right to use the MTS brand in India since March 2009, while we started receiving royalties of 0.16% of SSTL's revenues. The agreement is limited to SSTL using the MTS brand in India and does not contemplate our participation in SSTL's operations. The terms also stipulate that we will act as the brand guardian to ensure brand usage and marketing communications adhere to our brand guidelines.

On October 1, 2010, we announced the launch of a refreshed logo which we believe better emphasizes the ideas of innovation and dynamism reflected in our recently introduced new slogan "a step ahead." Our logo and brand style refresh are among the goals of our brand positioning. The refreshed logo retains the same egg shape, but transforms the former logo into a 3D image of a white egg against a red background, which gives the logo a more dynamic and modern look and perception. This logo is aimed at graphically enhancing and modernizing the egg-shaped logo we have been using since 2006. In addition, we believe that the logo better symbolizes our dynamic and innovative approach to doing business and our stated mission of "creating the best client experience," and our slogan "a step ahead."

In December 2010, we acquired Sistema Telecom from Sistema, which gave us control over the universal brand featuring the egg-shaped symbol against backgrounds of various colors used by us and our affiliates operating in the telecommunications sphere.

In February 2012, MBRD a subsidiary of Sistema, announced a change of its name to MTS Bank OJSC, having agreed to use MTS brand owned by us as a basis for further development. During 2012, we took an active part in MTS Bank's re-branding, as well as in product and advertising development. Two campaigns, image-oriented and product-oriented, were implemented. The image campaign, "For many years we helped you to share your dreams, now we help you to fulfill them" was organized to inform consumers that we now offer not only telecommunications services, but also bank services through MTS Bank. The product-oriented campaign was organized to promote our MTS-Dengi banking card.

A new retail format was developed for MTS Bank. It includes our corporate style and colors with a new corporate color, Turkish blue. The new format offers modern consumer-oriented approach. Particularly it influences the way the internal space of the bank offices is organized.

In 2013, MTS was ranked number 82 in the BRANDZ™ Top 100 Most Powerful Brands (3 points up from last year with 11% year-to-year increase in brand value), an independent ranking published by the Financial Times and Millward Brown, a leading global market research and consulting firm. We were the first Russian company to join the ranks of the most powerful brands in the world in 2008 and we maintained or improved our position in every subsequent year.

We have historically enrolled the vast majority of our subscribers through a network of independent dealers that operate numerous points-of-sale in places with high consumer activity, such as supermarkets, shopping centers, air terminals and markets. However, according to press reports, the financial downturn and tightening of the credit markets resulted in virtually all of the large national and regional mobile handset retailers in Russia facing liquidity issues or being on the verge of bankruptcy. In addition, as of April 1, 2009, we ceased working with Euroset, the largest mobile handset retailer in Russia, following Vimpelcom's indirect acquisition of a 49.9% stake. As a result of these factors, the share of our subscribers enrolled through these retailers dropped dramatically during the last quarter of 2008 and continued to drop in 2009. In the second half of 2010, we focused on improving our cooperation with certain of the large national and regional mobile handset retailers such as AltTelekom. We restored our cooperation and resumed working with Euroset in November 2010. In December 2012 MegaFon acquired a 50% stake in this retailer. Currently, Euroset is equally owned by our major competitors, MegaFon and Vimpelcom and remains a significant distribution channel for us. In 2013, we also entered into an agreement with Svyaznoy and our sales through its outlets increased significantly during the year. We also continued to develop our monobrand retail chain in 2013 and the vast majority of our subscribers were enrolled through it. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—our failure to further develop and sustain our distribution network as well as the reduction, consolidation or acquisition of independent dealers may lead to a decrease in our subscriber growth rate, market share and revenues."

In addition, we organized our retail operations under a wholly owned subsidiary, RTC. RTC handles all functions relating to our retail operations, including the management of points-of-sale, the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets. It also requires us to secure optimal locations for our points-of-sale and monitors the effectiveness of their operations.

In 2013, we continued to implement our strategy in retail operations by increasing the efficiency and optimizing the structure of our proprietary sales and distribution network. We expect to continue enhancing the efficiency and structure of this sales network, including through the optimization of points-of-sale locations, with the aim of maintaining our market position.

Our proprietary distribution network consists of MTS-branded franchise points-of-sale (third-party dealers operating under the MTS brand) and MTS-branded points-of-sale owned by us. As of December 31, 2012, our proprietary distribution network in Russia consisted of 4,462 points-of-sale, including 1,573 franchise points-of-sale and 2,889 points-of-sale owned by us.

In 2013, we have been focusing on optimizing the structure of our proprietary network in Russia. As of December 31, 2013, we operated 4,034 points-of-sale, including 1,197 franchise points-of-sale and 2,837 points-of-sale owned by us.

Our proprietary distribution network outside of Russia as of December 31, 2013, consisted of 38 points-of-sale in Ukraine 97 points-of-sale in Armenia and 7 points-of-sale in Turkmenistan.

For newly acquired mobile subscribers in Russia, we link commissions payable to a dealer on a monthly basis to the amount of revenues we receive during a half to one year period from the date a

subscriber is activated by a dealer. In addition, we have established caps, or a maximum commission amount payable to our dealers. The dealer commissions in Russia currently range between RUB 220 and RUB 1,900 ($6 and $58) per subscription.

In Ukraine, we link dealer commissions to the tariff package sold, category of subscriber, subscriber revenue, the duration of a subscriber being active, city of subscription and status of the specific dealer. We have different commission structures based on whether the subscriber is Prepaid, Postpaid or a CDMA-only subscriber (i.e., subscribers using only mobile Internet services). For each new subscriber, a dealer typically receives a one-time commission payment at the time the contract is signed or monthly payments based on the revenue generated from the subscriber. The dealer commissions in Ukraine for Postpaid tariffs consist of one-time commissions of $5 and we are entitled to retain the full commission amount if the subscriber stops using our services within five months following the month of activation. In addition, we may also pay monthly commission in an amount ranging from 30% to 36% of the revenues generated by the subscriber for a period of 12 months. Prepaid tariff commissions for activation of a subscriber are linked to the territory where a dealer operates. The period during which we pay a dealer commission depends on our market share in that territory and may vary from 4 to 8 months, and is the lesser amount of 50% of the subscriber's monthly invoice and $10.6. We also pay monthly dealer commissions of $15 for high quality, long-term subscribers, as well as a lump sum amount of between $156 and $3,150 to exclusive dealers who sell exclusively MTS Ukraine products and services. For CDMA subscriptions, we typically pay dealers a one-time fee of $5 upon subscriber activation, as well as monthly payments up to 12 months based on the revenue generated by the subscriber.

We believe that our method for paying commissions provides dealers with greater incentives to add new subscribers, reduces the risk of dealer fraud and improves our cash-flow management.

Demand for wireless communications services in Russia has grown rapidly over the last 10 years due to rising disposable incomes, increased business activity and declining prices due to intensified competition among wireless communications providers. As of December 31, 2013, overall wireless penetration in Russia was approximately 170.0%, or approximately 242.8 million subscribers, according to AC&M-Consulting.

The Russian market has achieved high levels of penetration in Moscow and St. Petersburg, where penetration reached approximately 216.6% and 211.5%, respectively, as of December 31, 2013, according to AC&M-Consulting. The average penetration rate in regional markets reached approximately 160.2% as of December 31, 2013, according to AC&M-Consulting.

The following table sets forth key data on Russia's wireless telecommunications market as of the dates indicated:

According to AC&M-Consulting, we accounted for 38% and 37% of subscribers in Moscow, 28% and 28% of subscribers in St. Petersburg and 31% and 31% of total Russian subscribers as of December 31, 2012 and 2013, respectively. We believe that the decrease in our market share in Russia, particularly in Moscow, is the result of our effort to restructure our subscriber base to reduce churn by focusing on loyal subscribers rather than infrequent users of our mobile services.

The primary mobile competitors in Russia include us, MegaFon and Vimpelcom, each of which has effective national coverage in Russia. Competition today is based on network coverage and quality, the level of customer service provided, roaming and international tariffs, local tariff prices and the range of services offered. For a description of the risks we face from increasing competition, see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies."

The following table illustrates the number of wireless subscribers for each network operator in Russia as of December 31, 2011, 2012 and 2013:

MegaFon. MegaFon, which operates GSM 900/1800/UMTS (3G) networks, is one of our primary competitors in Russia, and it is the second largest GSM wireless operator in Russia in terms of subscribers. According to AC&M-Consulting, MegaFon had a subscriber base of approximately 68.1 million subscribers in Russia as of December 31, 2013, including 11.8 million subscribers in the Moscow license area. At December 31, 2013, according to AC&M-Consulting, MegaFon had a 29% market share in Moscow, a 34% market share in St. Petersburg and a 28% market share of total wireless subscribers in Russia.

Given the increasing demand for data services we monitor the development of Skartel LLC, which operates under the YOTA trade mark. Currently YOTA offers LTE Internet services in 33 cities of Russia. Starting from October 2, 2013 Scartell LLC operates as a subsidiary of MegaFon.

Vimpelcom. In addition to MegaFon, we also compete with Vimpelcom, which is the third largest GSM 900/1800/UMTS (3G)/LTE wireless operator in Russia in terms of subscribers.

According to AC&M-Consulting, Vimpelcom had a subscriber base of approximately 56.5 million in Russia at December 31, 2013, including 13.2 million subscribers in the Moscow license area. At December 31, 2013, according to AC&M-Consulting, Vimpelcom had a 33% market share in Moscow, a 20% market share in St. Petersburg and a 23% market share of total wireless subscribers in Russia.

Other Operators. In addition to our principal competitors, MegaFon and Vimpelcom, we also compete with local GSM operators in several Russian regions.

In certain areas of Russia, we compete with Tele2, which had approximately 23.7 million subscribers as of December 31, 2013 according to AC&M-Consulting. Also, we compete with Rostelecom and its subsidiaries CenterTelecom, SibirTelecom, Dalsvyaz, Uralsvyazinform, Volga Telecom, North-West Telecom, Southern Telecommunications Company and Dagsvyazinform. According to AC&M-Consulting, Rostelecom had approximately 14.8 million customers as of December 31, 2013.

From 2003 to 2007, the Ukrainian wireless telecommunications market enjoyed rapid growth, in part, due to broader economic recovery in Ukraine, changes in ownership of the two major operators, the introduction of CPP (calling party pays) billing arrangements and the launch of the Beeline brand in Ukraine in April 2006 by Ukrainian RadioSystems ("URS"), a wholly owned subsidiary of Vimpelcom. The two largest wireless telecommunications providers in Ukraine are MTS Ukraine and Kyivstar who share 80% of the market, with 37% and 43%, respectively, as of December 31, 2013, according to AC&M-Consulting. The competitive environment in Ukraine changed after Vimpelcom Ltd., a Bermuda holding company, completed the acquisition of Vimpelcom and Kyivstar initiated earlier in 2010 pursuant to the restructuring of Vimpelcom. As a result, Vimpelcom Ltd. currently controls both Kyivstar and URS. Consequently, in October 2010, Kyivstar and URS each announced that they have started integrating their operating activities in Ukraine, including the re-branding of URS services under the Kyivstar brand and introducing unified tariffs and a common system for client relationships management. During the third quarter of 2012, in response to the previous quarter's weak results, Kyivstar intensified its marketing activities by launching a market strategy which was significantly similar to ours, offering "zero" prices for in-net calls nation-wide with different price points on the specified regional levels. In turn, we promptly launched a winter campaign called "Zero without compulsory charges," as daily charges were viewed as the principal negative factor for Kyivstar customers.

In 2013, Kyivstar launched new tariff plans without obligatory monthly payments and with a more detailed regionalization. In the fourth quarter of 2013 Ukrtelecom, the only UMTS license holder on the market was sold to System Capital Management (SCM), the co-owner of Astelit (another competitor operating in Ukraine), MNP launching has been postponed to the second half of 2014.

In 2013, Astelit continued its strategy of downmarket pricing on the voice-market. Tariff policies of all operators in Ukraine also stimulated data penetration and data consumption growth. Responding to the increasing competitive environment, we continued to focus on developing and marketing, providing superior customer service and positioning ourselves as offering the optimum price/quality proposition of voice and data services. While our average price per minute ("APPM") remained stable in 2013, our ARPU and MOU reduced due to growth of low-users in our customer base.

Overall wireless penetration in Ukraine in 2013 increased to 133.1%, or approximately 60.4 million subscribers, as compared to 126.1%, or approximately 57.7 million subscribers, in 2012, according to our estimates.

The following table shows the number of subscribers of the top mobile operators in Ukraine as of the dates indicated and the coverage area of MTS Ukraine and our competitors in Ukraine:

In Ukraine, we compete primarily with Kyivstar, a GSM operator with approximately 25.8 million subscribers as of December 31, 2013. Kyivstar offers wireless services using GSM 900/1800 technologies under the "Kyivstar," brand and fixed line services by the fiber-to-the-building technology ("FTTB") under the brand "Kyivstar Home Internet." Astelit offers services in GSM 900/1800 standards under the "life:)" brand.

In July 2006, we received a license to provide telecommunications services on the entire territory of Ukraine using the CDMA-450 standard. Following our development strategy in Ukraine, we launched a broadband network using CDMA 2000, deployed in the 450 MHz spectrum band, in November 2007. In 2010 we started to offer Prepaid CDMA tariffs. Our CDMA business in Ukraine faces wide competition from other operators, including Intertelecom (including CDMA Ukraine), People.net, 3mob (the only UMTS license holder in Ukraine), fixed broadband operators and Wi-Max operators. In 2012, we launched Rev B CDMA technology services in the Kiev Region.

As of December 31, 2013, overall wireless penetration in Armenia was approximately 117.3%, or approximately 3.75 million subscribers, according to our estimates.

The following table shows the number of subscribers as of the dates indicated and the coverage area of VivaCell-MTS and our competitors in Armenia:

As of December 31, 2013, VivaCell-MTS had approximately 2.43 million subscribers and a 65% market share, according to AC&M-Consulting and our estimates. In Armenia, we compete with ArmenTel, a fixed line and mobile operator wholly owned by Vimpelcom. ArmenTel holds a license in the GSM 900 standard for the entire territory of Armenia and a radio frequency permit for fixed line communications with CDMA equipment. Starting from 2009, we also compete with Orange (France Telecom), which was granted a GSM-900/1800 network license in October 2008.

As of December 31, 2013, overall wireless penetration in Turkmenistan was approximately 105.4%, or approximately 5.5 million subscribers, according to our estimates.

The following table shows the number of subscribers as of the dates indicated and the coverage area of MTS-Turkmenistan and our competitors in Turkmenistan:

MTS-Turkmenistan offers wireless services using GSM 900 and GSM 1800 technologies. As of December 31, 2013, MTS-Turkmenistan had approximately 2.0 million subscribers and a 36.6% market

share according to our estimates. In Turkmenistan, we compete with Altyn Asyr, a state-owned cellular operator which launched a 3G network in 2010 and was the only GSM operator from December 21, 2010 till August 30, 2012.

We customize our marketing efforts and pricing policies in each region of Russia and our other countries of operation by considering such factors as average income levels, the competitive environment and subscriber needs, all of which vary from region to region. Consistent with our marketing strategy, we have developed tariff plans to appeal to a broader market. The following table shows the mix between Prepaid and other subscribers, such as contract and corporate customers, for Russia and Ukraine for the periods indicated:

We are seeking to migrate our customers from advance payment plans to credit payment plans in an effort to stimulate ARPU and reduce churn. We endeavor to mitigate the risk of bad debt through the implementation of credit scoring algorithms that assess and help manage the risk of potential bad debt.

We currently have a unified system of tariff plans offered to subscribers throughout Russia. The unified system is aimed at achieving such benefits as clarity, simplicity and transparency for prospective subscribers by offering the same set of tariff categories throughout Russia. Under each tariff category, we offer different tariff plans with different connection fees, per minute call charges and a wide range of value-added services. All tariffs presented below are expressed in U.S. dollars converted from rubles using the exchange rate as of December 31, 2013.

By advertising on a national rather than regional or local level, we have been able to streamline and reduce our advertising and marketing expenses through unified advertising campaigns throughout Russia. Furthermore, we are able to convey to consumers a more uniform perception of our brand and services.

Currently, each of our tariff plans in Russia combines per minute usage charges, value-added services in packages and different monthly network access fees (with the exception of the Prepaid tariff plans) designed for different market segments. Our tariff plans are designed to be simple and appeal to particular segments of the market taking into account such factors as customer needs and consumption levels. Our tariff plans are currently divided into five categories—"Prepaid," "Smart," "Unlimited," "Data" and "Corporate"—with each category designed to target specific segments as follows:

Our tariffs vary from plan to plan. The description of tariffs and charges are, in each case, exclusive of VAT. As of December 31, 2013, the per-minute tariff for local calls within the MTS network varied from zero per minute to RUB 2.12 per minute. Different rates apply to local calls to other networks and vary from RUB 0.55 per minute to RUB 2.80 per minute. Higher rates apply to domestic long distance calls and rates for international calls vary from RUB 3.64 per minute for calls to the CIS to RUB 59.32 per minute for calls to other parts of the world. Periodically, we run various promotional campaigns, either on the federal or regional level, in which we provide temporary discounts to our regular prices.

We offer unified tariff plans throughout Ukraine and, in connection with our re-branding efforts in Ukraine during 2007 and 2008, we developed new regional and segmented tariff plans that focus on the differing needs of subscribers in the various market segments. Our tariff plans in Ukraine are oriented towards the following three main segments: (i) Postpaid Business, (ii) Postpaid Private and (iii) and Prepaid, which is further divided into voice oriented regionalized tariffs, data oriented regionalized tariffs and segmented tariffs.

As of December 31, 2013, the standard per minute tariff for calls in Ukraine varied from RUB 1.02 per minute to RUB 5.10 per minute. The standard per minute tariff for calls made within the MTS Ukraine network ranged from RUB zero per minute with limitations in minutes to RUB 4.90 per minute. Higher rates, ranging from RUB 0.61 per minute, applied to international calls to fixed lines of some countries in special service to RUB 306 per minute in standard international tariffs for satellites. All tariffs for MTS Ukraine subscribers are quoted in hryvnias. The tariffs set forth above are translated from hryvnias to Russian rubles using the official exchange rate of 0.24 hryvnias per RUB 1 as of December 31, 2013.

We enroll new Prepaid subscribers in an advance payment program, under which the subscriber prepays a specific amount of money to use our services. As of December 31, 2013, 85% of our consolidated subscriber base was enrolled in the advance payment program and 15% used the credit system.

Our advance payment system monitors each subscriber account and sends an advance warning on the subscriber's mobile telephone when the balance on the subscriber's account decreases below a certain threshold.

Under the credit payment system, customers are billed monthly in arrears for their network access and usage. We limit the amount of credit extended to customers based on the customer's payment history, type of account and past usage. As of December 31, 2013, subscribers using the credit system of payment had credit limits of up to RUB 98.8 million ($3 million) for key corporate customers in Russia. When a credit limit is reached, we block the telephone number until the balance is settled. There are no credit limits established for certain exceptional, high loyalty customers.

In 2007, we began to actively promote our credit payment system to our existing and new subscribers with the aim of migrating our subscriber base to the credit payment system from the existing advance payment system. In furtherance of this effort, during the period from 2009 to 2010, we introduced the "in full confidence" service (instead of the "Credit" service), which allows our Prepaid customers who subscribe to this service to continue using services when the balance on the subscriber's account becomes negative. We assign credit limits to our subscribers based on their payments and charge history (i.e., average balance usage) during the prior three months. As of December 31, 2013, subscribers using the "in full confidence" service had a maximum credit limit of RUB 28.7 thousands ($871). Customer service representatives can also set individual credit limits for subscribers. When the credit limit is reached, our billing system blocks the phone number until the balance is settled. Similarly to the credit payment system, the subscribers are billed monthly in arrears for usage. The invoice, which can be delivered to the customer by e-mail, fax, regular post and Internet, should be settled within 24 days. If the invoice is not paid five to seven days prior to the due date, the system sends an additional reminder. The telephone number is blocked on the 25^th day if the invoice is not settled.

We completed implementation of the Foris billing system in Russia in 2008 and have already begun to experience increases in our overall efficiency and reductions in our expenses. We are planning to complete the transfer of our individual subscribers in Ukraine to the Foris billing system by May 2014. In Armenia, we use the "Eskadenia" billing system. The Foris billing system allows us to offer all of our subscribers a uniform and consistently high level of service. It also supports the monitoring of account usage in real time. In addition, the system provides us with the ability to offer flexible tariff plans with various usage discounts and subscriber loyalty bonuses. Furthermore, we are able to provide our corporate subscribers with more sophisticated customized billing solutions. For example, our corporate subscribers who use multiple phone numbers in different regions of Russia now receive a single invoice, whereas our previous billing system could not support such a service.

In Russia, we offer our subscribers various ways to pay for our services, including by cash or credit card, wire transfer, Prepaid cards and express payment cards.

In Ukraine, our post-paid corporate and high-end subscribers receive an invoice which must be paid by a specified date. If the subscriber fails to pay, we block the phone number until the balance is settled. Our contract subscribers, who make an advance payment, are able to continue using our services once they reach a zero balance or until their accounts reach the credit limit specified in their service agreements. When the limit for such a subscriber is reached, we suspend our service until the balance is settled. We determine account terms and credit limits for each subscriber based on the subscriber's age, payment history and tariff plan.

In Ukraine we provide services to our Prepaid customers for as long as the balance on their accounts remains above zero and/or the tariff plans allow to use free-of-charge services without having the positive balance on the account.

In Ukraine we offer our subscribers various ways to pay for our services, including by cash in the assigned cash desks in our mono-brand shops, cash or card payment at the cash desk of the bank, through the recharge terminals, bank transfer from the current account (for legal entities), via internet and payment card of fixed nominal value.

We believe that to attract and retain customers, we must provide a high level of service in the key areas of customer assistance, care and billing. In each of the markets where we operate, we have contact centers that provide customer service 24 hours a day, seven days a week. Contact centers provide services to our customers through various channels (i.e., telephony, e-mail and fax). Customer service representatives answer inquiries regarding disconnection due to lack of payment, handset operation, roaming capabilities, service coverage and billing. A special group of customer service representatives handles customer claims and assists customers who wish to change their services. We regularly use automatic systems and independent analysis to monitor the contact centers' accessibility and customer satisfaction with the service level offered at such centers. To improve customer loyalty, reduce churn rate and promote our services, we conduct outbound calling campaigns using MTS staff, including the outbound contacts center and the customer relationship management laboratory, a system for managing our interaction with customers, clients and sales prospects.

In 2012, we finished the process of integration of our fixed line business customer service and assistance into us. As a result of this integration, any fixed line customer in Russia can now receive advice and expert assistance in our contact center.

In 2013, we created the MTS customer service data base to provide support in telephone service, to process claims, to improve collection of accounts receivable. The MNP project was started in MTS Contact Center to provide a leased line service for customers wishing to take advantage of mobile number portability.

We continuously work to improve customer satisfaction by providing our subscribers with convenient and functional self-service systems (e.g., Internet-Helper, interactive voice response ("IVR") and Mobile Helper). For instance, Internet-Helper is a service that, among other things, provides the customer with an opportunity to view information about his contract and personal information as well as manage certain account data. Similarly, Mobile Helper, among other things, allows a customer to receive information about his current balance, tariff plan details, as well as change service language and view bills for previous months. In 2012, we offered our customers the ability to pay for services using interactive voice menu IVR. As a result, the customers can now top up their accounts at any time using their bank cards and IVR.

In 2013, we have successfully implemented the service Voice Call Back, which allows the client not to wait for a response in Call Centre line, but request a call back. Our customers can now order the information on tariffs and services through the IVR system. In 2013, we started testing of speech recognition system.

In 2012, we established a telephone hotline support for our monobrand retail stores. The staff at our shops can call the hotline and get advice regarding our services. With the creation of the center of claims processing and support hotline mono-brand stores we are able to provide our clients with a high level of service at our retail stores.

We have back-office employees responsible for handling diverse customer inquiries. They also help to minimize the impact of technical problems and incidents on our customers. In addition, we have established customer retention departments throughout the territory of Russia to develop and implement customer retention programs with respect to all key customer segments and each of our primary service offerings. Our customer retention personnel are responsible for training front line employees on handling customer claims and suggestions, as well as following up with those customers who disconnected from our network to understand the reasons for the disconnection and properly respond to the changing needs of our customers. We continued pursuing a personalized approach in customer care using the Siebel CRM system, which helps us manage all customer-facing operations.

In 2014, we plan to implement an interactive IVR customer function, which allows a customer to use voice search to find the required information.

In 2008, in Ukraine, we launched a web portal and started to provide free access at special terminals in our sales offices for contract customers. Since 2009 we have further enhanced the quality of our customer service as a result of the complete integration of our IVRs and billing. In 2012, we made improvements to the IVRs menu to enhance its utility. In 2013, we continued to work on the improvement and expansion of self-service channels for subscribers and we were focused on auditing and optimizing internal customer service business processes.

In 2010, in Ukraine, we launched an online "self-service" for our Prepaid customers and significantly increased the number of its users in 2011. As part of online "self-service," we continued developing "self-care" functions through the web and IVRs (which provide, among other things, details of the subscriber's account, tariff plan specifications, amounts charged on credit cards, management of on-line service and charge details for contract subscribers). We also developed special services, such as shortened phone numbers, for broadband users and premium customers who require assistance. We increased the number of services available to our customers in contact centers and started telephone outbound sales through an outsourced contact center.

In 2012, we significantly increased retention and cross- and up-selling activities in our contact centers, including interactive presentations by agents, the IVR system and launch of new paid services. We also completed the process of simplifying and unifying customers care functions through our call centers. In 2012, we made improvements to our self-care channels, launched a mobile version of the Internet Helper for smartphones.

In 2012, we restructured the customer services department in MTS Ukraine which allowed us to increase efficiency of the management of customer service business processes. We made the customer assistance process in Ukraine more personalized by anticipating customer needs. We maintain a history of subscribers' requests and personalize the IVR for each customer profile, which depends on individual ARPU, region and other parameters. Based on these parameters we calculate the customer lifetime value index ("CLVI"), which we use to classify our subscribers, so that we can provide our priority customers with a wider range of services.

In 2013, we continued to work for improvement and expansion of our self-care channels. And we completely redesigned our IVR system and Web Chat and expanded the functionality and usability of Web Chat.

In 2013, we launched a new mobile application for Android OS. The application allows users to manage their account directly from their smartphones. We started the process of implementing an operational CRM system and the process of renewal of our contact center technical platform. We have also changed the approach to subscriber differentiation. In 2013, we finished the process of integration of our broadband subscribers into our system of customer service.

In 2014, we plan to continue to transform our call centers into effective channels for client relationship management. We plan to continue implementation of operational CRM system and complete the renewal of the technical platform for our contact center.

We launched our commercial 2G network in 1994, based on GSM-900 technology. From 1999 we significantly improved our 2G network capacity on the basis of GSM-1800 technology. From 2001 we implemented wireless data communication services based on GPRS technology with download data rate up to 85.6 kbit/s. In 2005 we modernized our GSM network to support EDGE technology and tripled data services rates. Today we continue supporting and modernizing our 2G network, and we put the prime focus on the development of our 3G and LTE networks in order to provide our subscribers with high-speed broadband wireless services.

Our 3G network, developed from 2009, have mainly reused our existing GSM infrastructure in order to improve the 3G network roll-out time and decrease capital and operating costs. At first, we deployed UMTS-2100 technology and provided data rates up to 3.6 Mbit/s. In 2010 we implemented 3G/HSDPA technology to boost download data rates up to 14.4 Mbit/s. In 2011 we began to re-allocate available GSM spectrum and launched UMTS 900 in the UMTS-2100 restricted areas: in the Moscow and in the Khabarovsk Regions. In 2012 we improved the data services rate in our network by up to 21 Mbit/s for the downlink using 3G/HSPA+ technology. From December, 2013 we activated second and third UMTS-2100 carriers on the 64% of our UMTS-2100 sites to improve capacity, and launched ultra high-speed services, based on Dual Carrier (DC-HSPA+) technology, with download rates up to 42 Mbps in 55% 3G sites in Russia.

The first commercial LTE FDD 2600 network launched in Armenia was ours in 2010. In September 2012, we launched a commercial LTE TDD 2600 network in Moscow. In our LTE network we provide data services with a download data rate up to 75 Mbit/s, and up to 25 Mbit/s uplink. We implemented MIMO2x2 and 64QAM technologies to maximize spectrum efficiency of the limited LTE frequencies. Our LTE network satisfied the requirements of 3GPP Rel.9 in line with available LTE customer equipment. In 2013, we started LTE Small Cells technology trials for the purpose of rating different deployments scenarios of HetNet RAN.

In December 2013 we were allowed to re-allocate the existing 900 and 1800 MHz spectrum to UMTS-900 and LTE-1800 all over the Russia. We plan to launch LTE-1800 network and expand out UMTS-900 network in 2014. Our strategy is to re-allocate available spectrum to the most efficient technology in the mid term period and provide competitive high-performance data services to our customers.

We use switching and other network equipment supplied by Motorola, Nokia Siemens Networks, Ericsson, Huawei, Alcatel-Lucent and other major network equipment manufacturers.

In the Moscow license area, we have been allocated frequencies spanning 2 × 11.4 MHz of spectrum in the GSM 900 frequency band and 2 × 24.6 MHz of spectrum in the GSM 1800 frequency band for operation of a dual GSM 900/1800 network and UMTS900 network. In 2011, we were allocated frequencies 2595-2620 MHz spanning 25 MHz for LTE TDD network deployment in Moscow and the Moscow Region.

In St. Petersburg and the Leningrad Region, we have been allocated frequencies spanning 2 × 9.6 MHz of spectrum in the GSM 900 frequency band (including 2 × 1.6 MHz in the E-GSM band) and 2 × 18.2 MHz of spectrum in the GSM 1800 frequency band for operation of a dual GSM 900/1800 network.

We have been allocated frequencies 1950-1965 MHz, 2010-2015 MHz and 2140-2155 MHz in the UMTS core frequency bands spanning 2×15 MHz (for FDD mode) and 5 MHz (for TDD mode) for UMTS network deployment for the entire territory of the Russian Federation.

We have been allocated frequency bands 2540-2550 MHz and 2660-2670 MHz spanning 2 × 10 MHz and frequency bands 798. 5-806 MHz and 839.5-847 MHz spanning 2 × 7.5 MHz for LTE FDD network deployment for the entire territory of the Russian Federation.

We have frequencies allocated to us for the operation of GSM 900 and GSM 1800 frequency bands in all regions of Ukraine. The radio frequencies allocated to us for the operation of GSM 900 span from 2 × 4.0 MHz of spectrum in Crimea to 2 × 5.8 MHz in the Nikolaev, Lugansk, Chernovtsy and Kirovograd Regions and in Kiev. We also have been allocated frequencies spanning from 2 × 20.0 MHz in the Kiev Region to 2 × 26.6 MHz in the Dnepropetrovsk Region for operation of GSM 1800 base stations. In addition, we have been allocated frequencies spanning from 453.35-457.1 MHz and 463.35-467.1 MHz in the CDMA-450 core frequency and bands spanning 3 × 1.25 MHz for CDMA-450 network deployment for the entire territory of the Ukraine.

We believe that we have been allocated adequate spectrum in each of our license areas.

The process of obtaining appropriate sites requires that our personnel coordinate, among other things, site-specific requirements for engineering and design, leasing of the required space, obtaining all necessary governmental permits, construction of the facility and equipment installation. In Russia, we use special radio planning software supplied by Aircom International and Mentum to assess new sites so that the network design and site development are coordinated. This software can create digital cellular coverage maps of our licensed areas, taking into account the peculiarities of the urban landscape, including the reflection of radio waves from buildings and moving automobiles and supports all necessary technologies, such as 2G, 3G and LTE. To use these tools more effectively we purchase high quality 3D digital maps for more precise planning. Used together, these software tools enable us to plan base station sites without the need for numerous field trips and on-site testing, saving us considerable time and money in our network build-out.

Base station site contracts are essentially cooperation agreements that allow us to use space for our base stations and other network equipment. The terms of these agreements range from one to 49 years, with the term of the majority of these agreements being one to five years. Under these agreements, we have the right to use premises located in attics or on top floors of buildings for base stations and space on roofs for antennas. In areas where a suitable base station site is unavailable, we construct towers to accommodate base station antennas, mainly on leased plots of land. We anticipate

that we will be able to continue to use our existing GSM 900 base station sites and to co-locate GSM 1800, UMTS 2100 and UMTS 900 base stations at some of the same sites. In 2013, we started the large-scale development of LTE network mainly using existing infrastructure.

To provide high quality service to our subscribers in Russia, we launched a global network operation center ("GNOC") in Krasnodar in July 2012. The GNOC experts carry out the monitoring of network equipment in six Macro-regions of Russia around the clock. We have two more operation and maintenance centers in Moscow and Voronezh. Our maintenance department, staffed 24 hours per day, performs daily network integrity checks and responds to reported problems. Our technicians inspect base stations and carry out preventative maintenance at least once every six months.

We have three network operation and maintenance centers: GNOC in Krasnodar and two local network operation centers in Moscow and Voronezh. We constantly control and monitor the performance of our network, call completion rate and other major key technical performance indicators. We use monitoring systems to optimize our network and to locate and identify the cause of failures or problems, and also to analyze our network performance and obtain network statistics. We have agreements with different suppliers for technical support services that allow us to obtain their assistance in trouble shooting and correcting problems with our network within the warranty period.

The GNOC in Krasnodar allows us to centralize such functions as monitoring and controlling of equipment, network planning and optimization, and also helps to solve incidents related to service interruptions. The GNOC experts have the technical ability to monitor network problems and unusual situations online in six Macro-regions of Russia. We expect that GNOC will strengthen our network's reliability and safety, as well as will create the necessary conditions to launch and implement new technologies and network standards.

In Voronezh, the operation and maintenance center takes the form of outsourcing partnership with Nokia Siemens Networks and is used for network monitoring in the Macro-region "Center."

The local network operation center in Moscow is used for network monitoring in Macro-region "Moscow."

Our networks in Ukraine, Turkmenistan, Armenia and Belarus are monitored by our local operation and maintenance centers in each country. In addition to the monitoring of network performance, these centers are used to analyze network quality parameters and provide reports and recommendations to management.

The handling of any significant network problems and outages is monitored and coordinated at our headquarters in Moscow, where we also manage the cross-functional coordination of our networks in all countries of operation.

We operate various types of communications networks, including mobile cellular, DLD/ILD and local fixed line and zonal fixed line networks.

Cellular operators must interconnect with fixed zonal, wireless, long distance and international telephone operators to obtain access to their networks and, via these operators, to the networks of other operators around the world. Cellular and fixed line operators must also obtain telephone numbering capacity to allocate to their subscribers. There are two categories of telephone numbers: "federal" 11-digit numbers (non-geographical numbering plan for cellular operators) and "local" seven-digit numbers (geographical numbering plan for fixed-line operators which can also be used as additional numbering capacity for mobile operators). In Moscow, both "federal" and "local" numbers

have been used in the 11-digit format since the beginning of 2011. We have entered into various agreements for the provision of local telephone numbering capacity with several local telecommunications operators in Moscow and in other regions of Russia and in Ukraine. We have also built our own local networks in certain cities within Russia (including Moscow) to provide local telephone numbering capacity to our subscribers. We are allocated federal telephone numbering capacity by the government and we provide interconnect services to other operators on the zonal level in all regions of Russia. Our fixed line zonal and local networks in Russia are interconnected with other operators. Zonal/local interconnect typically entails payment of a one-time connection fee per point of interconnect (E1) and a usage charge based on minutes of traffic. Operators with a substantial market position may also charge a guarantee monthly usage fee in case traffic is less than 30 kmin per E1.

The Ministry of Communications and Mass Media has allocated special numbering codes for federal 11-digit telephone numbers on a non-geographical basis for all cellular operators. We believe that we have been allocated sufficient numbering capacity for the development of our network. However, a combination of regulatory, technological and financial factors has led to the limited availability of local 7-digit telephone numbering capacity in Moscow and the Moscow Region. Moscow's "495" code and the Moscow Region's "496" code have already reached numbering capacity limits. As a result, the new "499" code was introduced in order to increase the Moscow numbering capacity, the "498" code was introduced to increase Moscow Region numbering capacity.

To meet subscriber demand and provide for an adequate inventory of numbering capacity, we previously entered into contracts with local fixed line providers for allocation of numbering capacity to us. However, the Ministry of Communications and Mass Media subsequently took the view that numbering capacity assigned to one operator could not be rented to other operators. Accordingly, we have entered into arrangements whereby fixed line operators make their numbers available to our subscribers via agency contracts between the subscribers and us acting on behalf of such fixed line operators. Our right to use numbering capacity ranges from five years to an unlimited period of time. As a result of our merger with Comstar, we have decreased the use of local numbering capacity of other operators. As of December 31, 2013, we had numbering capacity (federal and local) for approximately 24.72 million subscribers in the Moscow license area.

To provide our subscribers in Russia with DLD/ILD services, we have interconnect agreements with national operators Rostelecom, MTT (an affiliate of Sistema until March 18, 2009), Vimpelcom and other national transit operators. We have also built and operate our own DLD/ILD network, which allows us to interconnect directly to foreign operators and thereby decrease our interconnect costs. Most interconnect fees payable for connecting users of other operators' fixed line and wireless networks to our network are based on a one-time connection fee, a monthly fee per point of interconnect and usage by minute which vary depending on the destination called.

Russian legislation provides that fixed line operators with a substantial position in the market cannot refuse to provide interconnect or discriminate against one operator in comparison to another, and the interconnect rates of operators with a substantial position are regulated by the government. See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation—Competition, Interconnect and Pricing" and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues."

Interconnect and traffic transit between the networks of mobile operators in Russia occurs through direct channels connecting the switches of the different mobile operators within the same city; through the network of transit long distance operators, which connect the networks of different mobile operators in different cities; or through operators' proprietary long distance networks. For domestic long distance traffic transit, we use our DLD/ILD network and networks of different national

operators, including among others, MTT, Rostelecom and Vimpelcom. For ILD traffic transit, we primarily use our DLD/ILD network which is interconnected with more than 45 international carriers, including, for example, France Telecom S.A. and Deutsche Telecom A.G. We also have an interconnect between the DLD/ILD MTS network and the ILD networks of our subsidiaries, MTS Ukraine and K-Telecom, in order to provide the transit of international traffic.

In Ukraine, mobile operators are allocated numbering capacity by the NCCIR (National Commission for the State Regulation of Communications and Informatization). We believe that we have been allocated sufficient numbering capacity in Ukraine for the development of our mobile network. We also believe that we have been allocated sufficient fixed line numbering capacity with respect to the cities in which we are developing our fixed line network. We plan to develop fixed line network in other administrative districts of Ukraine. For this purpose we plan to purchase additional numbering capacity of 3000 numbers in three more cities. However, we estimate that it would take between 1.5 - 2 years to obtain additional fixed line numbering capacity should we seek such increased capacity.

Nearly all of our handset sales consist of tri-band GSM 900/1800/1900 and dual-band UMTS 900/2100 handsets, except for certain models in the low cost segment and touch-phones. These handsets, which function in the GSM 900, GSM 1800 and PCS-1900 standards, provide users with greater automatic roaming possibilities in Russia, Europe, the United States and Canada. We generally do not offer handset subsidies in Russia but do offer them in Ukraine to a limited number of contract subscribers as well as modem subsidies for GSM and CDMA users. For the years ended December 31, 2011, 2012 and 2013, we provided net handset subsidies of RUB 257 million, RUB 168 million and RUB 120 million, respectively, in Ukraine.

In 2009, we substantially changed the strategy and structure of our retail operations by significantly expanding our proprietary sales and distribution network both organically and through the acquisition of national and regional retail chains. We organized these operations under RTC, our wholly owned subsidiary. From 2009, RTC handles all functions relating to our retail operations, including the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets. RTC has entered into arrangements with Sony, Nokia, Samsung, HTC, Alcatel, Fly, Philips, Huawei and others to purchase handsets. We also offer an array of mobile telephone accessories. Since 2009 we have successfully been selling MTS branded phones. According to GFK, a leading market research agency, our MTS 970 branded smartphone was a top selling smartphone in August and September 2013.

In line with our strategy to promote data services the structure of our handsets sales changed in favor of affordable smartphones rather than premium-priced devices which resulted in a decrease in overall sales of handsets and accessories by 8.3% during 2013. We expect moderate growth in our handset sales in 2014. See also "Item 5. Operating and Financial Review and Prospects—A. Operating Results—Revenues—Sales of Handsets and Accessories."

We offer alternative and traditional fixed line communications services in over 185 cities across Russia, covering a population of over 53 million people.

Our alternative fixed line communications services include voice, data and Internet and pay-TV services for corporate and residential subscribers, as well as the provision of interconnect services to other communications operators and numbering capacity to their subscribers. According to Direct INFO, as of December 31, 2013, we are the largest operator in the Moscow residential broadband market in terms of subscribers, with a 27% market share. We also operate in Ukraine and Armenia, where we provide digital telephony communications services, data transmission, Internet access and the renting of channels.

Our traditional fixed line communications services are provided through incumbent operator MGTS. Through MGTS, we own "last mile" access to approximately 4.1 million households in Moscow, representing approximately 91% of the overall number of households in Moscow, according to Direct INFO. MGTS provides regulated and unregulated services, including:

For a list of the telecommunications licenses held by us, see "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Licenses."

We provide alternative fixed line communications services to corporate, operator and residential subscribers in over 185 cities throughout Russia. Specifically, we offer local voice, DLD/ILD voice, data and Internet and pay-TV services to our subscribers. Some of the interconnect tariffs we charge other telecommunications operators for in Moscow and certain other cities are regulated by the Russian government. We believe our fixed line subscribers typically evaluate our service and product offerings based on such factors as price, technology, security, reliability and customer service.

The following table presents certain operating data for our alternative fixed line business in Russia as of and for the years ended December 31, 2012 and 2013.

We target corporate subscribers covering a range of industries, such as business centers, hotels, financial institutions, professional services firms, consumer goods companies, manufacturers and companies involved in extractive industries, among others. These subscribers vary in size, ranging from large multinational and Russian corporations with thousands of employees to small-and medium-sized enterprises with up to several hundred employees. As of December 31, 2013, we had approximately 50,000 voice and 65,000 Internet corporate subscribers.

As further described below, we offer voice, data transmission and Internet and various value-added services to our corporate subscribers.

Voice Services. We provide a full range of alternative fixed line voice services to corporates in Moscow, the Moscow Region and other selected regions of Russia, which include local, zonal, and DLD/ILD services using our transmission network and leased capacity between major Russian cities. We also provide integrated voice and data services, voice over frame relay and certain integrated services digital network ("ISDN") services.

Data Transmission and Internet Services. We offer high quality data transmission services to corporates, which allow for data exchange between their various branches or offices located within Russia and internationally. For data transmission services, our network is capable of transferring data at speeds of up to 10 Gbps and utilizes various technologies, such as 10 GE, GE, ATM, TDM, VPN-MPLS, xDSL, LTE and Wi-Fi to provide high quality solutions at a relatively low cost. We endeavor to ensure the reliability of network connections by utilizing a full reservation approach to back up all elements of the network.

In addition, we offer a wide range of Internet services to corporates, including broadband Internet access, VoIP, VPNs and data center services using the following technologies: (1) NGN (up to 10 Gbps), (2) xDSL (up to 60 Mbps), (3) radio Ethernet (up to 27 Mbps), (4) Wi-Fi (up to 54 Mbps), and (5) LTE (up to 100 Mbps). We also provide continuous flexibility to upgrade their network capacity to handle additional Internet services. For example, we often integrate data transmission and Internet services for our clients as they expand their operations and need to interconnect and exchange data with newly opened offices and/or branches.

We offer a broad range of Internet packages that vary in terms of data transfer speeds and pricing, with higher tariffs for faster uploading and downloading capabilities. Corporates with xDSL-based broadband Internet packages generally experience data transfer speeds between 1 Mbps and 60 Mbps. In addition, we offer a premium broadband Internet service over our NGN in which subscribers enjoy data transfer speeds between 61 Mbps and 10 Gbps. The NGN provides subscribers with the benefit of the same uploading and downloading data transfer speeds, whereas Internet subscribers using an xDSL connection upload at speeds that are much slower than the one at which they can download.

We utilize MGTS' PDTN to provide high-speed reliable Internet services and create VPNs for our corporates.

Leased Channels. We provide corporate clients with the ability to rent high speed data channels. These "leased channels" are dedicated lines of data transmission.

Value-Added Services. We provide corporates with several value-added services, including Autosekretar and integrated solutions. The Autosekretar service is based on our proprietary intelligent network ("IN") and is designed to help our corporates to manage the reception and servicing of a large volume of incoming calls. The unique multi- channel telephone number assigned to customers will not change even if the customer moves to a different location in Moscow, and does not require the customer to install any equipment. In addition, this service allows all incoming calls to be transferred to other fixed or mobile telephone numbers in Russia or in other countries. The IN identifies a subscriber by phone number, phone card or password, which allows our customers to bill their subscribers for services and, if necessary, block access for subscribers who have a negative balance on their account.

In addition, we serve as general contractor for the provision of a full range of integrated solutions to subscribers wishing to establish a modern integrated communications infrastructure. Each solution is customized for subscriber-specific needs. In developing these customized networks, we are able to offer the following range of services: site survey, cost analysis and optimum project planning, assistance with government-related documentation, supply of equipment and operational, technical and maintenance support on an ongoing basis. Once the infrastructure is established or renovated, as the case may be, we typically provide digital voice communications, voice intelligent services, high-speed Internet

services, videoconferencing and other data transmission services. We intend to expand our service offerings to include customer premises management and network-centric IT solutions.

Fixed mobile convergence. Based on our fixed and mobile networks, we offer fixed-to-mobile convergence services to corporate clients providing use of their mobile phone as an extension of their private branch exchange ("PBX"). We also provide access to corporate IP-networks from a mobile phone via GPRS/EDGE/3G/4G.

We are the largest mobile operator in Russia, according to AC&M-Consulting. We also operate fixed-line local and zonal networks in Moscow and other cities for provision of telephony services to fixed-line subscribers and additional local numbers to mobile subscribers. In order to lower the costs of intercity and international traffic transition, we put into operation an intercity international network in December 2008.

According to Direct INFO, together with MGTS, we had approximately 77% of the total active numbering capacity in Moscow as of December 31, 2013. We now have approximately 323 local fixed networks in 63 regions of Russia, including Moscow, and 42 zonal fixed networks to provide telephony services to subscribers. Our integrated intercity\international network is interconnected to more than 43 international operators. As of December 31, 2013, we had more than 1100 interconnect agreements with national and international operators for interconnection of our fixed networks.

Voice Services. We provide voice services to residential and corporate subscribers. Like corporate subscribers, residential subscribers in each of the regions that we are present in seek a full range of high quality voice services equivalent to those provided in Western Europe. In addition to "basic" voice telephony services, we provide a number of additional services, such as call forwarding, call transferring, call waiting, conference, voicemail and Caller ID, among others.

Internet Services. We offer broadband Internet services to residential subscribers throughout Russia. As of December 31, 2013, we had 8% market share in the Russian Federation together with Moscow where we had a 27% share, according to Direct INFO. Depending on the Internet connection speed, we charge residential subscribers a subscription fee of RUB 300-RUB 2,100 ($9.2-$64.2) per month in Moscow and a subscription fee of RUB 150-RUB 3,500 ($4.6-$106.9) in other regions of Russia. We do not charge a connection fee in Moscow and in most of the Russian regions.

Pay-TV. We operate a TV service based on IPTV service over ADSL and GPON technologies in Moscow. In addition, we offer pay-TV services based on DVB-C (digital television via cable connection), analog cable transmission and MMDS (wireless cable) technologies in most of the regions in which we are present. Since November 2013, we connect our subscribers only to digital TV. A set-top box allows pay-TV subscribers to access more than 150 channels of digital quality and 37 channels of HD quality from a television. International and Russian channels are included as part of the basic services package. As of December 31, 2013, we had approximately 132.4 thousand pay-TV subscribers in Moscow and approximately 2.5 million subscribers in other regions of Russia.

Our pricing structure is designed to appeal to large numbers of consumers with various interests and purchasing power, and varies significantly between regions. We charge a subscription fee of RUB 99-RUB 1099 ($3.0-$32.7) per month in Moscow and a subscription fee of up to RUB 120-RUB 900 ($3.7-$27.5) in other regions of Russia, depending on the number of channels included in the package. We also offer bundled Internet and pay-TV services for RUB 399-RUB 2,100 ($12.2-$64.2)

per month in Moscow and RUB 419-RUB 1,049 ($12.8-$32.1) in certain other regions of Russia, depending on the speed of the Internet connection, the number of pay-TV channels being provided and level of competition in a particular region.

We provide traditional fixed line communications services through our subsidiary, MGTS, which is the incumbent fixed line PSTN operator in Moscow. MGTS owns Moscow's PSTN infrastructure, including switches, a transmission network, underground ducts, and owns or holds leases to properties housing its offices and equipment.

As of December 31, 2013, MGTS had approximately 4.27 million active lines in service, a cable network of over 95,470 km, a fiber optic network of over 20,122 km and 3,045 payphones. Currently, MGTS has focused its efforts on the deployment of GPON, IP/MPLS technologies and an IMS core. The old SDH equipment is being removed which results in the decreased number of E1 streams, a reduction in the copper network and the respective extension of the fiber-optic network.

In 2011, MGTS completed the digitalization of its network based on the special range of equipment MPN (Mediator Private Network), which allowed MGTS to complete the digitalization of the network two years ahead of schedule. The total installed capacity of the telephone network reached 4.9 million numbers as of December 31, 2013.

Residential subscribers accounted for approximately 81.8% of MGTS' total lines, corporates for 10.8% and public sector subscribers for 7.4%, as of December 31, 2013.

MGTS holds licenses and regulatory approvals to provide, among others, the following services:

As the only licensed PSTN operator in Moscow, MGTS is considered a natural monopoly under Russian antimonopoly regulations. Consequently, most of the services provided by MGTS are subject to governmental regulation. The Federal Tariff Service regulates MGTS' tariffs for voice telephony services provided to its PSTN subscribers, including monthly subscription fees, installation fees and local call charges. Operating revenues from regulated services accounted for approximately 59% of service operating revenues of our traditional fixed line business in 2013, 62% in 2012 and 69% in 2011. The percentage decline is connected with gradual growth of operating revenues from non-regulated services as a proportion of the overall operating revenues in 2013 and 2012 as compared to 2011. The Federal Tariff Service sets the tariffs MGTS can charge taking into account cost of services, network investment and a certain profit margin, and the current tariffs fully compensate MGTS for the cost of services provided to residential and government subscribers. According to Russian legislation, MGTS is allowed to petition the Federal Tariff Service for tariff increases upon certain conditions, such as inflation or increases in the cost of services. Historically, MGTS has petitioned the relevant Russian government agency for tariff increases once or twice per year. The Federal Tariff Service has permitted MGTS to increase its tariffs several times.

MGTS also provides a number of unregulated services. According to Russian legislation, DLD/ILD services provided by licensed non-monopoly operators, public payphones, data transmission services, value-added services and a number of other services are not subject to tariff regulation. Among others, MGTS provides the following unregulated services:

MGTS is not licensed to provide DLD/ILD communications services directly to its subscribers but must route such traffic through a licensed DLD/ILD operator. As a result, DLD/ILD traffic originated by MGTS subscribers is carried either by us, with these services included in MGTS' monthly bill, or by other providers of DLD/ILD services, who bill MGTS subscribers directly or pay MGTS an agency fee for processing their bills.

The following table presents certain operating data for our traditional fixed line business as of and for the years ended December 31, 2012 and 2013.

MGTS' subscriber segments and the services provided to each subscriber segment are further described below.

MGTS provides basic regulated voice services to residential and corporate subscribers using its PSTN facilities and copper "last mile" access. Tariffs for these services are established by the Federal Tariff Service.

In addition to basic voice services, MGTS also provides its residential and corporate subscribers with digital telecommunications services, Internet and VPN deployment services, rental of high-speed communication channels, intelligent voice and various other services.

The following table illustrates MGTS' regulated tariff development in the period from February 1, 2010, to March 1, 2014:

MGTS provides interconnect, traffic transmission and leased line services to other communications operators. Interconnect is carried out on the local and zonal levels in accordance with terms and conditions that are publicly disclosed. MGTS also provides additional services to operators interconnecting to MGTS' network, including access to emergency service, information and customer care numbers.

MGTS has also established an active presence in the data transmission market. Through its PDTN, MGTS can establish VPNs for other operators as well as provide other data network services. Operators can also rent space and utility systems from MGTS to house their network equipment.

To promote our product and service offerings, we use various communication channels for advertising and marketing, including direct marketing, printed mass media, television, Internet, radio, directories, outdoor advertising, advertising in the subway, special promotions and cross promotions. Through these various advertising and marketing channels, we intend to further develop our brand recognition. Our marketing strategy is designed to create a unified brand for each of our various product and service offerings with the aim of becoming a single source for all of our subscribers' communications needs.

We also actively promote our services to existing subscribers with special bundled product offerings aimed at servicing their communication requirements and enhancing subscriber loyalty. Our advertising and marketing materials are aimed primarily at the promotion of MTS brand. All fixed-line products are offered and marketed under this brand. However, when we enter new markets and acquire existing companies, we have to use both brands in advertising — MTS and the one popular in a certain area. This is done to decrease churn as customers tend to express strong loyalty towards local brands. We then gradually decrease presence of the local brand and this allows us to make MTS a market leader in a given region in future. Our advertising and marketing efforts are designed to convey a positive image of us to the market as a leading communications operator focused on customer satisfaction.

As the incumbent PSTN, MGTS has not invested significantly in sales and marketing. In 2013 MGTS continued realization of its long-term modernization program on GPON, therefore, the biggest part of advertising budget was spent on convergent products promotion like Double and Triple Play (an offer bundling two and three services) with the use of GPON technology. GPON allows us to provide higher quality services than our competitors and to increase the number of our subscribers and revenue from Internet and pay-TV services in Moscow. By the end of 2013, more than 708,000 subscribers were transferred to GPON.

In 2014, we are continuing the development of GPON technology and aim to double the number of our subscribers by the end of the year.

We compete with a number of fixed line telecommunications operators servicing Moscow, St. Petersburg and other major Russian cities. Moscow is the largest and most competitive of these markets. Our primary competitors include:

The following table sets forth the corporate subscriber market shares of the primary fixed line operators (including both alternative and incumbent operators) in Moscow as of December 31, 2013:

In the corporate subscriber segment, we generally compete on the basis of network quality, individual and bundled service offerings, customer service, installation time, geographical presence and pricing.

The following table sets forth the market shares of the primary fixed line operators (including both alternative and incumbent operators) for voice services in Russia as of December 31, 2013:

As Moscow's only PSTN operator, MGTS faces limited competition in the market for residential local telephony services in Moscow. As of December 31, 2013, it provided local voice telephony services for approximately 95% of all residential subscribers in Moscow, according to Direct INFO.

In the alternative voice services market, we generally compete based on the availability of bundled packages comprising broadband Internet access and pay-TV services, value-added services, network quality, installation time and customer service.

According to Direct INFO, as of December 31, 2013, broadband Internet penetration of households was 54% in Russia. The following table sets forth the market shares of the primary operators in the residential broadband Internet market in Russia as of December 31, 2013:

According to Direct INFO, as of December 31, 2013, pay-TV penetration was 65% in Russia. The following table sets forth the market shares of the primary operators in the TV market in Russia as of December 31, 2013:

In the TV market, we generally compete on the basis of pricing, channel selection and content, individual and bundled service offerings, customer service and installation time.

We establish prices for our unregulated services and different subscriber segments based on certain common considerations, policies and goals. For example, we generally seek to establish competitive prices based on market rates for the services we offer and below market prices when our lower-than-average costs or economies of scale allow us to do so. We also offer subscribers bundled service packages with several services offered together at a discount to the cost of ordering each individual service separately and to promote additional services to our existing subscribers. In addition, we often offer promotions to our various subscriber segments waiving or discounting installation fees in order to attract new subscribers or promote new services.

With regard to corporates, we generally aim to derive the bulk of our operating revenues from monthly payments. Thus, depending on the scale and type of services ordered, we will often discount or waive installation fees.

For services offered to other communications service providers, we aim to generate most of our operating revenues from monthly payments and by offering an array of value-added services.

We develop tariffs for service offerings to residential subscribers with the aim of attracting new subscribers, as well as expanding the services used by existing subscribers in order to generate higher ARPU.

As a result of our acquisitions of Comstar and Evrotel, we became one of the largest operators of the Internet long-haul backbone networks in Russia. We continue to develop our long-haul backbone network through the build-out of a fiber optic infrastructure, based on 100G technology, and acquisitions of other Internet backbone service providers. We currently have a fiber optic network of approximately 147,000 km, which also allows us to operate an optical transport network using dense wavelength division multiplexing technology.

In addition, we have our own IP MPLS network, which is capable of providing Internet and L2/L3 VPN services, as well as deliver other media products, such as digital television and internet protocol television, to regional networks for the use in our fixed line and mobile operations, as well as for our wholesale customers. Our IP MPLS backbone network covers most of Russia and Ukraine and is present in most of the European and U.S. Internet exchange points, such as DE-CIX in Frankfurt, NETNOD in Stockholm, AMS-IX in Amsterdam, PARIX in Paris, LINX in London, Equinix in Ashburn and New York, NIIX in New York and Any2 in Los-Angeles. In 2011, we also established connection to FICIX in Helsinki. More than 75% of our international Internet traffic is delivered through settlement-free peerings with other large networks. The remaining international Internet traffic is delivered through direct connections with certain of the largest networks. All internet traffic in Russia is delivered through settlement-free peering with the largest ISPs in Russia.

The network infrastructure we maintain in Moscow is substantially different to the infrastructures we use in the regions. In Moscow, we have primarily grown organically, while our regional development has largely been through the acquisition of companies with different business models and a focus on different services. As a result, the network infrastructures in the regions outside Moscow and the

technologies used to support such infrastructures are different from the network infrastructure established in Moscow and which we currently own.

The Moscow telephone network consists of 23 switching nodes (10 TDM switches and 13 soft switches) with total capacity of over 1,000,000 subscribers.

The Moscow Region telephone network consists of 13 soft switches with total capacity of around 100,000 subscribers.

All of our PSTN switching centers are connected to a digital transport network, which uses SDH technology and covers the entire territory of Moscow and most of the Moscow Region. The network ensures the functioning of our digital ATSs and their connectivity with analog and digital equipment of PSTNs of other operators. The digital transport network includes a trunk core STM-64, with connected half-rings STM-16 and STM-4. Multiplexers of access level are connected to trunk nodes by means of fiber-optic lines that organize streams STM-4 and STM-1. There are 1,000 multiplexers. The management of the transport network and digital ATSs is carried out remotely from network operation centers.

For the provision of Internet access, IP-telephony and other services, we have our own IP MPLS network, the core of which is constructed as IP MPLS rings with routers connected to each other by means of 10 GE channels. In addition, separate routers are used for inter-carrier connections and are connected to the core routers by means of 10 GE interfaces.

As of December 31, 2012, our wireless broadband network in Moscow and the Moscow Region included 60 base stations in the 5 GHz frequency band. Our radio-relay communication lines included 25 links and it also had 115 Internet hot-spots using Wi-Fi technology as of December 31, 2013.

As of December 31, 2013, outside of Moscow and the Moscow Region, we provide cable Internet access to 7.8 million households and cable TV access 8.6 million households. Among the access equipment used are Ethernet switches, IP DSLAM, ONT (PON) and Optical Receivers. We mainly use FTTB technology for internet access, which can provide speeds up to 1 Gb/se and about 500 channel CATV. In 2011, we started to roll-out DVB-C technology for cable TV service. In 2013, we started to roll-out a hybrid TV service.

In Moscow and regions as an Internet traffic supplier, we mainly use MTS own IP Backbone network described in the "transport network" section.

The acquisition of Comstar provided us with an opportunity to use MTS fiber optic lines for fixed network development. Optical network construction in cities is carried out on the basis of fixed and mobile business needs. When we modernize and construct new networks, we deploy fixed and mobile equipment on the basis of "collocation" method.

Our principal suppliers are Ericsson, Nvision Group, our related party, Cisco Systems , Huawei, Nokia Siemens Networks for switching equipment; ECI Telecom, Tellabs and Alcatel Lucent for transport network equipment; Cisco Systems, Huawei and Alcatel Lucent for Internet and data network equipment; Secure Media for crypto-protection conditional access software; and Tandberg TV (Ericsson), Irdeto for broadcasting equipment. All of our equipment is supplied directly through authorized dealers.

Our results of operations are impacted by certain seasonal trends. Generally, revenue is higher during the second and third quarter due to increased mobile phone use by subscribers who travel in the summer from urban areas to more rural areas where fixed line penetration is relatively low, as well as an increase in roaming revenues and guest roaming revenues during these quarters. Quarterly trends can also be influenced by a number of factors, including new marketing campaigns and promotions, and may not be consistent from year to year.

In the Russian Federation, the federal government regulates telecommunications services. The principal law regulating telecommunications in the Russian Federation is the Federal Law on Communications, which provides, among other elements, for the following:

The Federal Law on Communications came into force on January 1, 2004, and replaced the law of 1995 regulating the same subject matter. The Federal Law on Communications creates a framework in which government authorities may enact specific regulations. Regulations enacted under the legislative framework in place prior to the enactment of the Federal Law on Communications continue to be applied to the extent they do not conflict with the Federal Law on Communications. The lack of interpretive guidance from the regulatory authorities regarding the new regulations and the uncertainty surrounding their compatibility with the regulations still in effect impedes our ability to assess effectively the full impact of the new regulations under the Federal Law on Communications on our business.

The Federal Law on Communications, which confers broad powers to the state to regulate the communications industry, including the allocation of frequencies, the establishment of fees for frequency use and the allocation and revocation of numbering capacity, significantly modifies the system of government regulation of the provision of communications services in Russia. In particular, licenses to provide communications services in territories where frequency and numbering capacity are limited may be issued only on the basis of a tender. In addition, the Federal Law on Communications provides for the establishment of a "universal services reserve fund" which is funded by a levy imposed on all operators of public networks, including us.

The Russian telecommunications industry is regulated by several governmental agencies. These agencies form a complex, multi-tier system of regulation that resulted, in part, from the implementation of the Federal Law on Communications, as well as from the large-scale restructuring of the Russian

government in March 2004 and subsequent restructuring in May 2008. The system of regulation is still evolving and further changes are expected. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Countries of Operation—Political and Social Risks—Political and governmental instability in Russia and other countries of our operations could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

The Ministry of Communications and Mass Media is the federal executive body that develops and supervises the implementation of governmental policy in the area of communications and coordinates and controls the activities of its subordinate agencies. The Ministry has the authority to issue certain regulations implementing the federal law on communications and other federal laws.

The Federal Service for Supervision in the Sphere of Telecom, Information Technologies and Mass Communications is a federal executive body that supervises and controls certain areas of communications and information technologies, including:

The Federal Agency of Communications is a federal executive body that implements governmental policy, manages state property and provides public services in the area of communications, including the allocation of numbering capacity and the certification of equipment for compliance with technical requirements.

The State Radio Frequencies Commission is an inter-agency coordination body acting under the Ministry of Communications and Mass Media which is responsible for the regulation of the radio frequency spectrum, develops long-term policy for frequency allocation in the Russian Federation and decides on the allocation of frequency bands.

FAS is a federal executive body that supervises competition regulations and enforces the Federal Law on Protection of Competition and the Federal Law on Natural Monopolies and the regulations enacted thereunder. FAS controls certain activity of natural monopolies, including monitoring their execution of certain obligatory contracts, and can issue mandatory orders as provided for in the Federal Law on Natural Monopolies.

Other regulatory authorities. In addition, the Federal Tariff Service regulates certain tariffs in the sphere of telecommunications, including the tariffs on the local and DLD calls by subscribers of public switched telephone networks and installation and subscription fees. The Federal Service for Supervision in the Area of Consumer Rights Protection and Human Well-Being is responsible for the enforcement

of sanitary regulations, including some authority over the location of telecommunications equipment, and supervises the compliance of companies with the regulations relating to the protection of consumer rights. The Federal Registration Service is responsible for registering certain telecommunications infrastructure that is considered real property in accordance with Government Decree No. 68 dated February 11, 2005.

Telecommunications licenses are issued based on the Federal Law on Communications and Government Decree No. 8 dated January 12, 2006 on Approval of Regulations for Holding a Competitive Tender for Receipt of Telecommunication License. Under these regulations, licenses may be issued and renewed for periods ranging from three to twenty-five years. Several different licenses to conduct different communication services may be issued to one entity. Provided the licensee has conducted its activities in accordance with the applicable law and terms of the license, renewals may be obtained upon application to the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media. Officials of the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media have broad discretion with respect to both issuance and renewal procedures.

A company must complete a multi-stage process before the commercial launch of its communications network. A company must:

Effective January 1, 2004, licenses may be transferred in case of mergers or other reorganizations of the licensee upon application by a transferee as a new license holder. Additionally, the Ministry of Communications and Mass Media has declared that agreements on the provision of telecommunications services must be concluded and performed by the license holder.

If the terms of a license are not fulfilled or the service provider violates applicable legislation, the license may be suspended or terminated. Licenses may be suspended for various reasons, including:

In addition, licenses may be terminated for various reasons by a court, including:

The license may also be terminated by the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media in a number of cases, including liquidation of a license holder. A suspension or termination of a license may be appealed in court.

Frequencies are allocated for a maximum term of ten years, which may be extended upon the application of a frequency user. Under the Federal Law on Communications, frequency allocations may be changed for purposes of state management, defense, security and protection of legal order in the Russian Federation with the license holder to be compensated for related losses. Further, frequency allocations may be suspended or terminated for a number of reasons, including failure to comply with the conditions on which the frequency was allocated.

The following one-time license fee is payable irrespective of the number of regions covered by the license: RUB 6,000 (equivalent to $181 as of December 31, 2013) for services involving, among other things, the use of a frequency spectrum and the lease of communication channels. The license fee for a license received through a tender or auction is determined by the terms of such tender or auction.

In addition to licensing fees, a government decree enacted on June 2, 1998, required payment of fees for the use of radio frequencies for cellular telephone services. The payment procedure was established by a government decree enacted on August 6, 1998, which required that all wireless telecommunications services operators pay an annual fee set by the State Radio Frequencies Commission and approved by FAS for the use of their frequency spectrums. On January 1, 2012, a new government decree came into force which provides that fees for the use of radio frequency spectrums consist of a one-time fee and an annual fee. The fees are determined according to the methodology approved by the Ministry of Communications and Mass Media.

Furthermore, the Federal Law on Communications provides for the establishment of a "universal services reserve fund" for the purpose of supporting communications companies operating in less developed regions of Russia through the financing, construction and maintenance of telecommunications networks in low-profit and unprofitable sectors. This reserve fund is aimed at eliminating the practice of cross-subsidies by compensating operators for certain mandatory, loss-making local services in rural and sparsely populated areas. It is funded by a levy imposed on all operators of public networks, including us, in the amount of 1.2% of revenues from telecommunications services less the amount of taxes paid by subscribers. The universal service fund concept has been used in some developed countries and in Eastern Europe.

The Federal Law on Communications empowers the Russian government to determine and annually review the list of licensing requirements applicable to various communication services being licensed. The list of licensing requirements was enacted by Government Decree No. 87 dated February 18, 2005, as amended. Licenses also generally contain a number of other detailed conditions, including a date by which service must begin, technical standards and certain other terms and conditions. We have either commenced service by the applicable deadline or received an extension of the applicable deadline for all of our licenses.

Government Decree No. 532 adopted on June 25, 2009, sets forth the types of communications equipment that is subject to mandatory certification. Communications equipment must be certified, or its compliance with the established requirements must be declared and proven in the interconnected

communications network of the Russian Federation, which includes all fixed line and wireless networks open to the public. All our networks must be certified. The Federal Agency of Communications issues certificates of compliance with technical requirements to equipment suppliers based on the Agency's internal review. In addition, a Presidential decree requires that licenses and equipment certifications should be obtained from the Federal Security Service to design, produce, sell, use or import encryption devices. Some commonly used digital cellular telephones are designed with encryption capabilities and must be certified by the Federal Security Service.

Further, certain high-frequency equipment, a list of which was approved by Government Decree No. 539 dated October 12, 2004 (as amended) manufactured or used in the Russian Federation requires special permission from the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media. These permissions are specific to the entity that receives them and do not allow the use of the equipment by other parties. Failure to receive such certification could result in the mandatory cessation of the use of such equipment.

The Federal Law on Communications requires federal regulatory agencies to encourage competition in the provision of communication services and prohibits the abuse of a dominant position to limit competition. The Federal Law on Communications provides that telecommunications tariffs may be regulated in cases provided for by legislation. The Federal Law on Communications and Presidential Decree No. 221, enacted on February 28, 1995, as amended, on Measures for Streamlining State Regulation of Prices (Tariffs) allow for regulation of tariffs and other commercial activities of telecommunications companies that are "natural monopolies." Government Decree No. 637, dated October 24, 2005, authorized the Federal Tariff Service to set the following tariffs for the natural monopolies in the communications market, including:

In addition, the Federal Law on Natural Monopolies establishes the legal basis for federal regulation of natural monopolies, including those in the communications market, and provides for governmental control over tariffs and certain activities of the natural monopolies. The Federal Law on Natural Monopolies outlines the types of transactions for which a regulated entity must obtain prior FAS approval and establishes the general principle that regulated entities may not refuse to provide regulated services to certain types of consumers. Regulated entities are also subject to continuous reporting requirements, including submitting plans for capital investments.

The Federal Tariff Service maintains a Register of Natural Monopolies whose tariffs are controlled and regulated by the state. A telecommunications operator may be included in this register upon a decision by the Federal Tariff Service based on the Service's analysis of the operator's activities and the market conditions.

Our subsidiary, MGTS, was added to the Register of Natural Monopolies in 2000. In addition, our subsidiary Comstar-regions was added to the Register of Natural Monopolies in 2009. As a result, MGTS and Comstar-regions are subject to the requirements of the Federal Law on Natural Monopolies including, inter alia, the following:

In addition, FAS is authorized by law to maintain a register of companies holding a market share in excess of 35%. Companies included in this register may become subject to certain restrictions in conducting their business, including in relation to pricing, acquisitions, geographical expansion, and associations and agreements with competitors. We are categorized by FAS as a company with a market share exceeding 35% in Ivanovo Region, Magadan Region, Sakhalin Region, Udmurt Republic and Nenets Autonomous District. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate, the government may regulate our subscriber tariffs and restrict our operations."

The Federal Law on Communications also provides for the special regulation of telecommunications operators occupying a "substantial position," i.e., operators which together with their affiliates have, in the Russian Federation generally or in a geographically defined specific numerical zone, 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic. Comstar-UTS and MGTS were added to the register of telecommunications operators occupying a substantial position in 2005 and 2006, respectively. After the exclusion of Comstar-UTS from the register in February 18, 2013 MGTS is subject to the requirements of the Federal Law on Communications relating to operators occupying a substantial position in the public switched telephone networks including, inter alia, the following:

The Federal Law on Communications and implementation rules adopted by Government Decrees No. 161 dated March 28, 2005, and No. 627 dated October 19, 2005, also provides for government regulation of interconnect tariffs established by operators occupying a substantial position. In addition, such operators, including MGTS, are required to develop standard interconnect contracts and publish them as a public offer for all operators who intend to use such interconnect services.

Notwithstanding the above, fixed line operators not considered to occupy a substantial position and not included in the Register of Natural Monopolies, as well as mobile operators, are free to set their own tariffs. Also see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

In March 2006, the Federal Law on Communications was amended to incorporate a "calling party pays" scheme effective as of July 1, 2006. Prior to the implementation of the "calling party pays" principle, subscribers of fixed line operators could initiate calls to mobile phone users free of charge. Under the current system, fixed line operators charge their subscribers for such calls and transfer a percentage of the charge to mobile operators terminating such calls. The percentage transferred to mobile operators is regulated by the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media and is known as the settlement rate. Any reduction of the settlement rate by the regulator could have a negative impact on our average monthly service revenues per subscriber and margins.

On December 1, 2013, a mobile number portability law came in force within the Russian Federation. It allows subscribers, whether corporate or individuals, to retain their mobile telephone numbers when switching from one mobile network operator to another. This may lead to the reallocation of the mobile subscriber base in Russian Federation among existing operators and may lead to intensification of competition and an increase in our costs. Also see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—Regulatory changes in Russia, including the reduction of settlement rate, the mobile number portability principle and others may have a material adverse effect on our financial condition and results of operations."

Administration of State Service on Special Communications and Information Protection of Ukraine. This body is responsible mainly for establishing and overseeing technical policies and standards in the sphere of telecommunications. Previously these functions were carried out by the State Communications Administration.

The NCCIR. The functions of the NCCIR were formerly carried out by the NCRC (National Commission for Communications Regulation of Ukraine). Established by a Decree of the President of Ukraine in August 2004, the NCRC was vested with the powers of the central regulatory body in the sphere of telecommunications on January 1, 2005 pursuant to the Telecommunications Law described below. It consisted of seven members and a chairperson. The NCRC commenced its activity in April 2005 when the chairperson and its members were appointed as required by the Telecommunications Law.

The NCRC has been responsible for issuing licenses for telecommunications services and use of radio frequencies commencing January 1, 2005, as well as various other responsibilities of the SCA from that date. According to the amendments to the Telecommunications Law introduced in July 2011, the NCRC was replaced in August 2011 with the NCCIR, which now consists of six members and a chairperson. The NCCIR is currently responsible for issuing licenses for telecommunications services and use of radio frequencies, and other functions of former NCRC.

The State Center for Radio Frequencies of Ukraine (the "SCRF"). While licenses for radio frequencies for wireless communications are issued by the NCCIR, SCRF is the authority responsible for all technical issues related to the use of radio frequency resources and, in such proxy, is also involved in the issuance of radio frequency licenses. In particular, the SCRF determines frequency availability and technical aspects of frequency allocation, as well as provides the NCCIR with an expert opinion in relation to each application for radio frequency. The SCRF also monitored use of the frequencies and continued monitoring compliance with the license terms and carried out physically

inspections of operators and providers of telecommunications services until the establishment of the State Inspection of Communications, as described below. The SCRF also independently issues individual permissions for the use of radio-electronic and radio-emitting equipment, its development, import, sale and purchase, and maintains a data base of IMEI codes of mobile telephones.

The State Inspection of Communications (the "SIC"), established by the new Telecommunications Law, was a division of the NCRC. The SIC was responsible for the general supervision of the telecommunications market and the use of radio frequency resources. The SIC also monitored compliance with license terms, physically inspected operators and providers of telecommunications services and, together with the SCRF, reviewed cases relating to administrative violations in the areas of telecommunications and radio frequencies. In July 2011, the SIC was abolished, and inspectors tasked with supervision were re-assigned to the NCCIR.

The AMC is charged with the administration of competition legislation and the protection and regulation of economic competition in Ukraine, including economic competition among industry participants in the telecommunications sector.

The principal legislation regulating the telecommunications industry consists of the Law on Telecommunications dated November 18, 2003, (the "Telecommunications Law"), and the Radio Frequencies Law dated June 1, 2000, (the "Radio Frequencies Law").

The Telecommunications Law provides for, among other things, equal rights for private entrepreneurs and legal entities to offer telecommunications services, fair competition and freedom of pricing. The Telecommunications Law also sets forth the legal, economic and organizational framework for the operation of companies, associations and government bodies forming part of the telecommunications networks. The licensing of telecommunications services, the requirements for equipment certification and liability for violations of Ukrainian legislation on telecommunications are also determined by this legislation. The Telecommunications Law also governs the relations between the state and local governmental bodies, telecommunications operators and users of telecommunications services and radio frequencies.

The Telecommunications Law addresses various areas of telecommunications services in Ukraine, including numbering requirements, tariff and settlement regulations, interconnect, public telecommunications services, market access rules and licensing issuance and renewal. The Telecommunications Law also significantly expands the definition of the telecommunications services market, including in its scope Internet Protocol telecommunications, transmission of data and facsimile communications.

The Telecommunications Law also restructured the regulatory bodies governing the area of telecommunications. It provided for the creation of the NCRC, which, between January 1, 2005, and July 5, 2011, had been responsible for many of the functions formerly handled by the SCA. In August 2011, the NCRC was replaced with the NCCIR, which is authorized, inter alia, to issue regulations for telecommunications services, issue telecommunications licenses to operators and providers, issue frequency licenses, request information from operators, providers and authorities, impose administrative penalties and maintain the register of the operators and providers. The NCCIR is also authorized to conduct hearings and to resolve disputes among operators concerning the interconnect of telecommunications networks.

In July 2010, the Telecommunications Law was amended with provisions on mobile number portability and national roaming obligations. In April 2013 the NCCIR (formerly NCRC) adopted regulations which allow subscribers to retain their mobile telephone numbers when switching from one mobile telecommunications operator to another.

On August 25, 2011, the NCCIR enacted national roaming regulations. Accordingly, telecommunications operators were permitted to conclude agreements on national roaming and prescribed to provide this service as described in the regulations (e.g., must inform users on roaming prices and maintain quality of service on the same level for own subscribers and subscribers of operators with whom roaming agreements are signed). Foreign investments in Ukrainian telecommunications operators are not limited; however, in order to provide telecommunications services in Ukraine an entity must be located on the territory of Ukraine and registered in accordance with Ukrainian legislation.

The Radio Frequencies Law sets forth comprehensive rules regarding the allocation, assignment, interrelation and use of radio frequencies, the licensing of the users of radio frequencies and other relevant issues.

Commencing January 1, 2005, the NCCIR (formerly NCRC) has assumed responsibility for issuing telecommunications licenses and frequency licenses pursuant to the Telecommunications Law and the 2004 amendments to the Radio Frequencies Law. Licenses are issued for the following types of telecommunications services:

Starting from July 5, 2011, the leasing of electric communications channels no longer requires licensing.

An operator that is granted a telecommunications license may not commence the provision of wireless telecommunications services until it receives a frequency license. The issuance of a frequency license is, in turn, subject to the availability of radio frequencies in the respective regions of Ukraine. Frequency licenses are issued for specific bandwidths within certain frequency spectrums in specific regions. The GSM and UMTS spectrum is presently considered to be the most commercially attractive for telecommunications operators. It is currently deemed to be virtually impossible to obtain a license for GSM frequencies in major Ukrainian cities because most of the GSM radio frequencies in such cities are already licensed to the existing GSM operators, including us. UMTS radio frequencies are currently allocated for special users, in particular, the Ministry of Defense. In September 2009, the NCRC announced plans to launch a tender for a single 3G/UMTS mobile services license in Ukraine. However, the NCRC canceled the planned tender in November 2009 following a decision by the President of Ukraine to put the tender and conversion of the radio frequencies on hold.

Following the election of Viktor Yanukovich as Ukraine's new President in February 2010, a working group was created in order to fulfill the assignment of Ukraine's Cabinet of Ministers regarding the conversion of frequencies.

In October 2010, the NCRC proposed an updated plan that stipulates carrying out the conversion within eight months of November 2010 and at a cost of 841 million hrivnias in one stage by means of releasing the whole 100 MHz frequency range. In March 2011, the NCRC developed a draft regulation (which has yet to be approved by the Ukrainian government) for the compensation of costs incurred by various governmental agencies (including the Ministry of Defense) that currently hold frequencies to be converted. In 2012, the NCCIR was planning to determine the specific requirements of a public tender

for the sale of frequencies for the development of 3G networks. The tender was not held in 2012 and is currently on hold. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Our inability to obtain a UMTS license in Ukraine on commercially reasonable terms, or at all, may negatively affect our competitive position in Ukraine."

Under applicable legislation, licenses for telecommunications services may be issued and renewed for periods of not less than 5 years, with the actual period generally ranging from 10 to 15 years. Renewal of a license is made by an application submitted to the NCCIR at least four months prior to the expiration of the license term. NCCIR officials have broad discretion with respect to both the issuance and the renewal of licenses. The Telecommunications Law further provides that the NCCIR must grant licenses on a first come-first served basis within 30 days from submission of an application. If resources are limited or consumer interests so require, the NCCIR may adopt a decision to limit the number of licenses. In this event, the law requires that such decision is made public along with the rationale and that the licenses be allocated through a tender.

In accordance with the Radio Frequencies Law, the NCCIR issues a frequency license concurrently with the issuance of a telecommunications license for the type of services requiring use of radio frequency resources. A telecommunications operator that has the respective telecommunications license may apply for licenses for additional radio frequency bands. Frequency licenses may not be issued for a period shorter than the term of the relevant telecommunications license.

Under applicable legislation, a public tender or an auction for a radio frequency license must be held by the NCCIR if demand for radio frequency resources exceeds available resources. Radio frequency licenses issued on the basis of a public tender or an auction for the same type of radio technology must include identical conditions regarding the radio frequency bands and development period. Telecommunications operators are allowed to apply to the NCCIR for redistribution of the radio frequency resources previously allocated to them.

Applicable legislation prohibits the transfer of a license by the licensee, including by means of assignment or pledge of a license as collateral, and agreements regarding the provision of telecommunications services must be executed and performed by the actual licensee.

Licenses generally contain a number of detailed conditions, including the date by which service must be commenced, terms of network deployment and territory coverage, the requirement to use only certified equipment, the technical standards which must be considered and the requirement to comply with all environmental regulations. Frequency licenses issued after January 1, 2005 will also contain the date by which the radio frequency resources must be fully utilized.

Telecommunications operators' activities are subject to strict regulations, especially regarding electromagnetic compatibility; construction and technical maintenance of a telecommunications network must be carried out in accordance with specific regulations applicable in Ukraine. Telecommunications operators must submit periodic reports to the NCCIR on the amount and quality of services provided under the telecommunications license. We believe that we are in compliance with the applicable laws and regulations related to our Ukrainian licenses.

Some licenses also provide that services for persons entitled to certain social benefits must be provided at or below certain minimum thresholds established by Ukrainian legislation in effect at that time.

If the terms of a license are not fulfilled or the service provider violates legislation, the license may be suspended or terminated. Both telecommunications services licenses and radio frequency licenses may be terminated for various reasons, including:

Decisions of the NCCIR with respect to the termination of licenses may be appealed to a court.

MTS' Ukraine license to construct and maintain the telecommunication network and provide services using such network was due to expire on December 3, 2013. In October 2013, MTS Ukraine submitted an application to the NCCIR requesting the renewal of the license. On October 15, 2013, the NCCIR refused to renew the license and recommended that MTS Ukraine receive a new license to provide operations in the telecommunications sphere. On October 21, 2013, MTS Ukraine filed a lawsuit against the NCCIR with a demand to renew the license. On November 19, 2013, a court decision was issued in favour of MTS Ukraine. The decision obliged the NCCIR to renew the license. The NCCIR appealed against the court decision. On January 15, 2014, the court of appeal issued a judgement in which the court refused to sustain the NCCIR appeal. On January 28, 2014, the NCCIR renewed MTS Ukraine license until December, 2018. On January 27, 2014, the NCCIR filed anappeal against the court of appeals' order. The NCCIR's appeal is yet to be considered.

For installation on a telecommunications network either the manufacturer or the vendor must provide the operator with a document of confirmation to the normative documents compliance and documentary confirmation of inclusion in the registry of technical equipment that can be used in the telecommunication network. The Administration of State Service on Special Communications and Information Protection of Ukraine sets the technical standards for equipment designed for use in telecommunications networks in Ukraine.

The Radio Frequencies Law provides that users of radio frequency resources must obtain permits for the operation of radio-electronic and radio-emitting equipment, except for equipment used on a permit-free basis in accordance with this law. In order to obtain such operation permit, a company is required to file an application with the SCRF. The Radio Frequencies Law also requires producers and importers of radio-electronic and radio-emitting equipment to be used on the territory of Ukraine to register such equipment with the NCCIR.

The Telecommunications Law provides that one of the purposes of the licensing of telecommunications services is to encourage competition and de-monopolization in the telecommunications industry.

Ukrainian antimonopoly legislation prohibits a company operating in Ukraine from abusing its dominant position in its market to gain, inter alia, an unfair or anti-competitive advantage in the provision of its services or products. A legal entity is deemed to be in a dominant position if such entity has no competitor in the market or is not subject to substantial competition due to restricted access or entry barriers for other business entities. Further, Ukrainian antimonopoly legislation provides that a company shall be deemed dominant if its market share in the respective product market exceeds 35% unless such company proves that it faces significant competition in the respective product market.

According to AC&M-Consulting, MTS Ukraine had a 37.5% market share of the wireless communications market in Ukraine as of December 31, 2013.

A telecommunications operator which is found by the AMC to have a dominant position in the market, in particular, may specifically be required to:

In June 2010, the AMC confirmed a finding dating back to May 2009 that eight mobile operators, including MTS Ukraine and its closest competitors, have a dominant position on the market for interconnecting to their own mobile networks. As a result, the interconnect fees charged by these operators, including MTS Ukraine, for termination of calls on their networks are currently regulated by the NCCIR. In February 2010, the NCRC approved interconnect rates for telecommunications operators found by the AMC to have a dominant position. Thus, MTS Ukraine was obligated to charge interconnect rates established by the NCRC, which were 0.35-0.40 hryvnias per minute excluding VAT (approximately RUB 0.011—RUB 0.012 as of December 31, 2013). See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations."

In December 2010, the Telecommunications Law was amended to introduce the term "significant market power operator." An operator qualifies as a SMP operator if its share of gross revenue from the provision of traffic transfer services on fixed or mobile telecommunications networks during the last 12 months exceeded 25% of total gross revenues of all telecommunications operators for the same services during the same period. An operator can be classified as a significant market power operator on either the fixed telecommunications market, the mobile telecommunications market, or on both. Such an amendment could allow the NCCIR to recognize certain operators, including us, as operators with significant market power (rather than operators with dominant positions) and to regulate consequently their fees for traffic transfer services (rather than interconnect fees for termination of calls on the operators' networks).

In July 2010, the term "significant market power operator" was changed by the amendment to the Telecommunications Law which came into effect on January 1, 2011. From this date, the significant market power operator will be qualified in the market which is defined by NCCIR.

On October 20, 2011, the NCCIR issued a decision, which recognizes all mobile operators, including MTS Ukraine, as SMP operators on the market of call termination on their own networks.

On December 1, 2011, the NCCIR approved an interconnect rate of 0.36 hrivnias per minute excluding VAT (approximately RUB 0.011 as of December 31, 2013) which came into effect on January 1, 2012, for all SMP operators on the market of call termination on their own networks.

The Telecommunications Law also extends the power of the NCCIR to receive financial and economic data from telecommunications operators. Such information allows the NCCIR to analyze the Ukrainian telecommunications services market in order to determine which operators (if any) have a dominant position and which ones (if any) are significant market power operators for purposes of regulating fees such operators can charge for interconnect and traffic transfer services. In addition, the financial and economic data permits the NCCIR to better regulate the interaction of operators with regard to traffic transfer services and to assist without court dispute settlement. New amendments to the Telecommunications Law also set forth the methodology for fee determination that can be charged for traffic transfer services based largely on a calculation that includes an operator's base cost plus profit level of certain services. Furthermore, in order to prevent "dumping" fees, operators that do not have a dominant position nor significant market power are prohibited under the Telecommunications Law from charging fees less than those charged by the regulated entities, but can charge more if they choose.

Due to the currently large market shares held by MTS Ukraine and Kyivstar in Ukraine, we believe that the AMC may determine that only these two operators (and not the current eight operators) have dominant positions on the market. If so, we and Kyivstar would remain the only regulated operators in Ukraine and, as a result, we could suffer a significant decrease in our interconnect revenues as well as an increase in the interconnect fees we pay to other operators not deemed to have a dominant position or significant market power.

On December 30, 2011, the AMC commenced an investigation of the telecommunications services market for the purpose of determining dominant market force abuse by MTS Ukraine in relation to international roaming services. During the investigation, MTS Ukraine has been continuously providing the AMC with documents and information officially requested by the AMC. A similar investigation was commenced in relation to our main competitor in Ukraine, Kyivstar. In the event that the AMC finds any operator has abused its dominant market force in relation to international roaming services, it could fine such an operator for up to 10% of its revenue for the previous year, calculated in accordance with local accounting principles.

On September 27, 2012, the AMC commenced an investigation into the telecommunications services market for the purpose of determining any abuse of a dominant market position by MTS Ukraine in relation to national mobile communications services. During the investigation, MTS Ukraine has been continuously providing the AMC with documents and information officially requested by the AMC. A similar investigation was commenced in relation to our main competitor in Ukraine, Kyivstar. In the event that the AMC finds any operator in abuse of its dominant market force in relation to international roaming services, it could fine such an operator for up to 10% of its revenue for the previous year, calculated in accordance with National Accounting Regulations (Standards) ("NR(S)AU").

On December 19, 2012, the AMC issued a mandatory recommendation following its international roaming services investigation. According to this recommendation, MTS Ukraine is obliged to decrease its tariffs on international roaming services to a competitive level. In January 2013, MTS Ukraine provided the AMC with the required information, necessary for fulfill this recommendation.

The cases on international roaming services and national mobile communications services have been closed, with MTS Ukraine receiving the relevant notices from the AMC on February 8, 2013 and February 11, 2013, respectively.

Please see also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations" for details of AMC of Ukraine investigations in respect of international roaming services and national mobile communications services.

The Telecommunications Law withdrew the authority of the Cabinet of Ministers of Ukraine to regulate the prices for telecommunications services.

In February 2006, the NCRC established maximum tariffs for the provision of electric communications channels by operators having a dominant position on the market and, in April 2009, it established maximum tariffs for fixed line public telecommunications services.

Although there are no additional regulations limiting the rates at which tariffs may be set for wireless telecommunications services, if the Antimonopoly Committee believes competition laws are violated, it can assert that tariffs are unfair and injurious to market competition. In such cases, the AMC may, inter alia, request the violating telecommunications operator to remedy the situation, in particular, by amending its tariff scheme, and impose fines on the company for an infringement.

Subject to the above, wireless operators are free to set tariffs at levels they consider appropriate.

Interconnect activity is regulated by the NCCIR. Operators may provide offers for interconnect to the NCCIR, and the NCCIR is required to publish on an annual or regular basis a catalog of such offers. Operators with a dominant position on the market are obliged to submit interconnect offers to the NCCIR for each catalog.

Interconnect is made pursuant to interconnect agreements between network operators as prescribed by the regulatory authorities. Such agreements are required under the law to contain certain provisions. An operator with a dominant position cannot refuse an offer to conclude an interconnect agreement with another operator, if the offeror has offered points of interconnect that were previously published by the NCCIR in the catalog of interconnect proposals.

The NCCIR is authorized to conduct hearings and to resolve disputes among operators concerning the interconnection of telecommunications networks. Decisions of the NCCIR are binding upon the parties in the dispute but a party to the dispute may appeal such a decision in court.

In May 2009, the AMC issued a finding that eight mobile operators, including MTS Ukraine and its closest competitors, have a dominant position in relation to the market for interconnecting to each of their respective networks. MTS Ukraine appealed this decision in June 2009, and the AMC suspended the decision pending resolution of the appeal. In June 2010, the AMC confirmed its earlier decision and interconnect fees charged by MTS Ukraine for terminating calls on its network are currently regulated. In February 2010, the NCRC established regulated interconnect fees for termination of calls on the networks of operators that have a dominant position. See "—Competition."

In October 2011, the NCCIR defined all of operators, that have operated in the Ukrainian market in the period from 2009 through 2010 as having significant market power (SMP-operators) for

termination traffic on their fixed and mobile networks (433 fixed and 8 mobile operators). Effective 1 January 2012, the NCCIR regulates the interconnection rates for all SMP fixed and mobile operators, including MTS Ukraine. The interconnection rates charged by long-distance operators are set up equal to rates charged by mobile operators.

The NCCIR regularly analyses the telecommunication market to determine operators with significant market power in this market. The last analysis of the market was carried out in October 2013. As a result of this analysis, 345 fixed and 7 mobile operators were defined as SMP-operators. The interconnect rates charged by SMP-operators have remained in place since January 1, 2012.

We own and occupy premises in Moscow at 4 Marksistskaya Street Bldgs. 1-4, 34 Marksistskaya Street Bldg. 10, 1/3 Vorontsovskaya Street Bldgs. 2 and 2a, 5 Vorontsovskaya Street Bldgs. 1 and 2, 13/14 Vorontsovskaya Street Bldg. 4, 8 Vorontsovskaya Street Bldg. 4, 12/12 Pankratievsky Pereulok, 2/10 Perviy Golutvinskiy Pereulok Bldg. 1 and 2, 4 Perviy Golutvinskiy Pereulok Bldg. 1, 9 Magnitogorskaya Street Building 1, 6 Vtoroy Vyazovskiy Proezd Building 1-3, 2A Konstantina Simonova Street, 19 Dmitrovskoye shosse Bldg. 2, 103 Prospect Mira, 42 Profsoyuznaya Street Bldg. 1, 24/2 Malaya Dmitrovka Street, 5/9 Malaya Dmitrovka Street Sheremetyevo Airport, 58\1 Ryazanskiy prospect, 60 Varshavskoe shosse, 27 Smolenskaya-Sennaya square Bldg 2, 27 Smolenskaya-Sennaya square Bldg 3, 6 Ostrovitjanova Street, 2 Mozhayskoe shosse, which we use for administration, sales and other service centers as well as the operations of mobile switching centers.

We also lease buildings in Moscow for similar purposes, including marketing and sales and other service centers. In addition, through our subsidiary MGTS, we own approximately 238 buildings located throughout Moscow, which serve as sales and customer service offices, house MGTS'

telecommunication equipment and are leased to third parties. We also own office buildings in some of our regional license areas and in Ukraine, and we lease office space on an as-needed basis. We believe that our properties are adequate for our current needs and additional space is available to us if and when it is needed.

The primary elements of our network are base stations, base station controllers, transcoders and mobile switching centers. Base stations occupy sites leased at selected locations in all the areas in which we provide network coverage. GSM, 3G and 4G technologies are based on an "open architecture," which means that equipment from one supplier can be combined with that of another supplier to expand the network. Thus, there are no technical limitations to using equipment from other suppliers.

The table below sets forth certain information on our network equipment as of December 31, 2013.

The following discussion of our financial condition and results of operations is intended to help the reader understand us, our operations and our present business environment and should be read in conjunction with our consolidated financial statements, related notes and other information included elsewhere in this document. In particular, we refer you to the risks discussed in "Item 3. Key Information—D. Risk Factors" for information regarding governmental, economic, fiscal, monetary or political policies or factors that could materially adversely affect our operations or your investment in our shares and ADSs. In addition, this section contains forward-looking statements that involve risk and uncertainties. Our actual results may differ materially from those discussed in forward-looking statements as a result of various factors, including those described under "Item 3. Key Information—D. Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements." Our reporting currency is the Russian ruble and our consolidated financial statements have been prepared in accordance with U.S. GAAP.

We are a leading telecommunications provider in Russia and the CIS, providing a wide range of mobile and fixed line voice and data telecommunications services, including transmission, broadband, pay-TV and various value-added services, as well as selling equipment and accessories.

According to AC&M-Consulting, we are the largest mobile operator in Russia and Armenia and the second largest in Ukraine in terms of mobile subscribers. As of December 31, 2013, we had a mobile subscriber base of approximately 102.4 million.

We are also the largest operator in the Moscow residential broadband market in terms of subscribers, with a 27.0% market share as of December 31, 2013, according to Direct INFO.

Our revenues for the year ended December 31, 2013, were RUB 398,443 million, an increase of 5.3% from the year ended December 31, 2012. Our net income attributable to the Group for the year ended December 31, 2013, was RUB 79,839 million, an increase of 169.3% from the year ended December 31, 2012 (mainly due to the situation in Uzbekistan, where our operations were terminated in July 2012 and our licenses were consequently withdrawn, for more details please see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" regarding suspension of our services in Uzbekistan" and Note 4 to our audited consolidated financial statements). Our net income from continuing operations for the year ended December 31, 2013 increased by RUB 13,597 or 21.4% to RUB 77,055 million, the increase was mainly attributable to one off gain recognized as a result of settlement of Bitel litigation (the gain totaled RUB 12,147 million) . Our revenues have historically increased through organic growth, as well as through acquisitions.

The acquisition of Comstar in 2009 and the subsequent merger have provided us access to important growth markets in corporate and residential broadband in furtherance of our strategy to develop convergent telecommunications services and evolve into an integrated telecommunications operator.

We also aggressively expanded our proprietary retail and distribution network over the course of 2011, 2012 and 2013, both organically and through the acquisition of several national and regional retail chains. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Sales and Marketing—Sales and Distribution" and "—Acquisitions."

We require significant funds to support our subscriber growth, primarily for increasing network capacity, maintaining and modernizing our mobile and fixed line networks, developing our network in the regions and continuing the build-out of our LTE, 3G and broadband Internet networks.

Our cash outlays for capital expenditures (consisting of purchases of property, plant and equipment and intangible assets) for the years ended December 31, 2011, 2012 and 2013 were RUB 72,802 million, RUB 87,783 million and RUB 81,575 million, respectively.

We have financed our cash requirements through our operating cash flows and borrowings. Net cash provided by operating activities from continuing operations for the years ended December 31, 2011, 2012 and 2013 was RUB 107,019 million, RUB 134,856 and RUB 159,924 million, respectively.

Our borrowings consist of notes and bank loans. Since 2001, we have raised a total of $3.0 billion (approximately RUB 92.8 billion as at the date of issue) through eight U.S. dollar-denominated unsecured bond offerings in the international capital markets, as well as ruble-denominated bonds totaling RUB 96 billion. Our bank loans consist of U.S. dollar, euro and ruble-denominated borrowings totaling approximately RUB 116.4 billion as of December 31, 2013.

We repaid approximately RUB 45,191 million of indebtedness in 2013. As of December 31, 2013, the total amount available to us under our credit facilities amounted to RUB 5.0 billion. We had total indebtedness of approximately RUB 219.1 billion as of December 31, 2013, including capital lease obligations, compared to approximately RUB 232.1 billion as of December 31, 2012.

Our total interest expense for the years ended December 31, 2012 and 2013 was RUB 15,498 million and RUB 17,673 million, net of amounts capitalized, respectively. See Note15 to our audited consolidated financial statements for a description of our indebtedness.

Our reporting currency is Russian Rubles. Our and our subsidiaries' functional currencies are the ruble in Russia, the hryvnia in Ukraine, the U.S. dollar in Uzbekistan, the manat in Turkmenistan and the dram in Armenia. See "—Certain Factors Affecting our Financial Position and Results of

Operations—Currency Fluctuations" and "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

We align our business into two reportable segments, Russia and Ukraine, to effectively manage both the mobile and fixed line operations as an integrated business and to respond to the demands of our customers. The Russian reportable segment arose due to the aggregation of two similar operating segments: MTS Russia and MGTS Russia.

The "Other" category does not constitute a reportable segment. It includes both the results of a number of other operating segments that do not meet the quantitative thresholds for separate reporting, such as Armenia, Turkmenistan and the headquarters. See also Note 26 to our audited consolidated financial statements for segment information.

We manage our operations separately in each country in which we operate due to the different economic and regulatory environments, which require us to separately and specifically tailor our marketing and investment strategies. Our management evaluates our performance based on the operating results in each country. Thus, as of December 31, 2013 we had four operating segments that corresponded to our countries of operations and business activities: (1) Russia, (2) Ukraine, (3) Armenia and (4) Turkmenistan, which include our mobile and fixed line communications operations in Russia, Ukraine, Armenia and Turkmenistan, respectively.

The net operating revenues of our segments for the years ended December 31, 2011, 2012 and 2013 were as follows:

Below we provide certain operating data not included in our financial statements that we believe is useful for evaluating our business and results. The data focuses primarily on our mobile operations, particularly in Russia and Ukraine, which comprise the most significant share of our revenue in the periods presented, and is among the information routinely reviewed by our management as part of their regular evaluation of our performance.

The following table shows our mobile subscribers by country as of the dates indicated:

We had approximately 75.32 million subscribers in Russia as of December 31, 2013, and a leading 31.0% market share of total mobile cellular subscribers in Russia, according to AC&M-Consulting. Overall penetration in Russia was at approximately 170.0%, according to AC&M-Consulting. We had approximately 22.66 million subscribers in Ukraine as of December 31, 2013 and, according to AC&M-Consulting, a 37.0% market share of total mobile cellular subscribers in Ukraine. In addition, as of December 31, 2013, we had approximately 2.44 million subscribers in Armenia, and 2.02 million subscribers in Turkmenistan, representing a 65.2% and 36.6% market share, respectively, according to AC&M-Consulting and our estimates. For a description of our fixed line subscriber base, see "Item 4. Information on Our Company—B. Business Overview—Fixed Line Services."

We define mobile churn as the total number of subscribers who cease to be a subscriber during the period (whether involuntarily due to non-payment or voluntarily, at such subscriber's request), expressed as a percentage of the average number of our subscribers during that period. We view the subscriber churn as a measure of market competition and customer dynamics. The following table shows our Russian and Ukrainian subscriber churn for the periods indicated.

The churn rate is highly dependent on competition in our license areas and those subscribers who migrate as a result of such competition.

Our churn rate in Russia decreased to 36.3% during the year ended December 31, 2013, as compared to 42.4% for the year ended December 31, 2012, as we improved the quality of customer service by developing our proprietary mono-brand retail network in Russia and revised the pattern of

interaction with dealers. In addition, we continued to offer our popular tariff plan "Super MTS" (free calls to all subscribers of MTS Russia), updated options for unlimited mobile Internet, further improved network quality and enhanced data rate by expanding our 3G capabilities. We expect that the expansion of the MTS-Bonus loyalty program and further development of our mono-brand retail network will allow us to keep churn rate stable in 2014, stimulate value-added services usage and promote subscriber loyalty through superior customer service.

The churn rate in Ukraine decreased to 26.1% for the year ended December 31, 2013 from 30.5% for the year ended December 31, 2012. This decrease was achieved by adjusting our tariffs in response to changes in the market and economic environment and by focusing on better managing our subscriber base.

We calculate mobile average monthly service revenue per subscriber by dividing our service revenues for a given period, including interconnect, guest roaming fees and connection fees, by the average number of our subscribers during that period and dividing by the number of months in that period. The following table shows our average monthly service revenue per Russian and Ukrainian subscriber based on our current calculation methodology and average monthly minutes of use per Russian and Ukrainian subscriber for the periods indicated.

Average monthly service revenue per subscriber in Russia increased to RUB 307.9 for the year ended December 31, 2013, from RUB 297.1 for the year ended December 31, 2012. This increase was coupled with an increase in subscriber base in 2013 to 75.3 million from 71.2 million, and was caused by inflation and an increase in the disposable income of the general population. Average monthly minutes of use per subscriber in Russia increased to 327 minutes in 2013 from 304 minutes in 2012 mainly due to decrease in tariffs for on-net traffic and various roaming-related offers.

In Ukraine, average monthly service revenue per subscriber decreased slightly to RUB 149.7 for the year ended December 31, 2013, from RUB 152.7 for the year ended December 31, 2012. The average monthly minutes of use per subscriber decreased to 574 minutes in 2013 from 597 minutes in 2012 due to the influx of lower value subscribers.

Our mobile service subscriber tariffs in Russia and Ukraine are not currently regulated by any organization or governmental authority. The interconnect fees we charge to other operators for terminating calls interconnecting to our mobile network are not regulated in Russia, but are regulated in Ukraine. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations," "—If we are found to have a dominant position in the markets where we operate, the government may regulate our subscriber tariffs and restrict our operations" and "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

Certain of our fixed service tariffs are regulated, including tariffs charged by Moscow incumbent operator MGTS for installation fees, monthly subscription fees and local call charges, as well as interconnect and traffic transit tariffs. The interconnect tariffs charged by us are also regulated by the Federal Agency on Communications.

Usage fees include amounts charged directly to our subscribers, both for their usage of our network and for their usage of other operators' GSM networks when roaming outside of our service area. We generally bill our subscribers for all outgoing calls. Since July 2006, pursuant to an amendment to the Federal Law on Communications, mobile operators in Russia have been prohibited from charging their subscribers for incoming calls.

The prices for outgoing calls to other cellular operators and to the public service telephone network are usually higher than charges for outgoing calls within our network. The usage fees charged for a call originating on our network depend on a number of factors, including the subscriber's tariff plan, call duration, the time of day when the call was placed and the call destination. Usage fees as a percentage of our total revenues were 30.0% in 2011, 27.6% in 2012 and 26.4% in 2013. Usage fees as a percentage of our total revenues have been decreasing largely due to the increase in revenues from value-added services as a percentage of our total revenues.

Interconnect fees, which are fees for connecting users of other operators' fixed line and wireless networks to our network, comprised 11.0%, 11.3% and 11.1% of our total revenues in 2011, 2012 and 2013, respectively. The fluctuations of interconnect fees as a percentage of our total revenues were largely due to the increase in revenues from value-added services, which grew faster than our revenue from interconnect fees. However, in absolute terms, interconnect fees grew by RUB 1.2 billion in 2013 as compared to 2012 and we expect it to continue to grow due to the increases in traffic volumes from our competitors.

Value-added services as a percentage of our total revenues comprised 18.2% in 2011, 21.5% in 2012 and 24.1% in 2013. We offer our subscribers an array of value-added services. The increase in 2013 in revenue from value-added services was due to an increase in data traffic, resulting from active marketing initiatives, expansion of mobile internet penetration and overall improvement of the quality of these services.

Monthly subscription fees consist of fixed monthly charges for network access and access to additional services. Monthly subscription fees as a percentage of our total revenues represented 7.6% in 2011, 7.1% in 2012 and 6.8% in 2013, respectively. The fluctuations of the monthly subscription fees as a percentage of our total revenues corresponds to the change in the share of subscribers with monthly subscription fees in the subscriber mix from year to year and the subscription-based services we offer. Many of our monthly subscription fee-based tariff plans also include a usage fee-based component for minutes used over a certain number of prepaid minutes. The percentage of our total revenues represented by usage fees as compared to monthly subscription fees will continue to be affected by

changes in our tariff plans, as well as the relative product mix between usage fee-based tariff plans versus monthly subscription fee-based tariff plans.

Roaming fees for guest subscribers include amounts charged to other cellular operators for their subscribers i.e., guest roamers, utilizing our network while traveling in our service area. We bill other cellular operators for calls of guest roamers carried on our network. Roaming fees for guest subscribers as a percentage of our total revenues represented 0.8% in 2011, 0.7% in 2012 and 0.6% in 2013. We generally expect that roaming fees will continue to decline as a percentage of our total revenues due to the large increase of revenues from our value-added services. In addition, roaming tariffs between mobile operators have a tendency to decrease relative to the increase in the total number of mobile users. We may also be pressured or required to lower our roaming tariffs by FAS. See "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Antimonopoly Proceedings."

Roaming fees for our own subscribers include amounts charged to our subscribers while traveling out of our service area. Roaming fees for own subscribers as a percentage of our total revenues represented 8.7% in 2011, 8.6% in 2012 and 8.6% in 2013. We expect that our roaming fees will decline as a percentage of total revenues due to the continuing growth of revenues from our value-added services.

Connection fees consist of charges incurred by subscribers for the initial connection to our network and sign-up for value-added services. We defer connection fees and recognize them as revenues over the estimated average subscriber life in our network as described in Note 17 to our audited consolidated financial statements. Connection fees represented 0.3%, 0.3%, 0.2% of our total revenues in 2011, 2012, and 2013, respectively. We expect connection fee revenues to remain at a low level as a percentage of our total revenues.

Fixed service revenues which consist primarily of fixed line telephony services, broadband internet and pay-TV services, comprised 15.4%, 14.7% and 14.7% of our total revenues in 2011, 2012 and 2013, respectively. In absolute terms, the growth of our fixed service revenues was accompanied by an increase in regulated tariffs. We expect that it will continue to grow due to the further increase in regulated tariffs caused by inflation and future acquisitions.

Revenue from the sale of handsets and accessories as a percentage of total revenue comprised 7.5% in 2011, 7.6% in 2012 and 6.6% in 2013. The decrease in 2013 is attributable to a reduction in sales of premium priced smartphones as we refocused our retail strategy to promote affordable smartphones. We expect that sales of handsets and accessories will decrease as a percentage of total revenue due to the expected increase of revenues from our value-added services. We do not subsidize handset sales in Russia. In Ukraine, we subsidize handsets for some of our contract subscribers as well as modems for GSM and CDMA users. See "—Cost of Handsets and Accessories" below.

Interconnect and line rental. Interconnect and line rental charges include charges payable to other operators for access to, and use of their networks, which are necessary in the course of providing service to our subscribers. Interconnect charges as a percentage of our total revenues represented 12.4% in 2011, 12.3% in 2012 and 11.9% in 2013. Line rental charges as a percentage of our total revenues represented 1.9% in 2011, 2012 and 2013.

We expect that interconnect expenses payable by us to other operators for termination of traffic generated by our subscribers will increase. Primarily, this increase will likely be attributable to the

growth in the volume of traffic resulting from our efforts to encourage greater usage through the introduction of new services, which may be supported by marketing campaigns.

We expect line rental costs to increase based on the number of base stations, base station controllers, the number and capacity of rented lines.

Roaming expenses. Roaming expenses consist of amounts charged by other cellular operators under agreements for roaming services provided to our subscribers while outside our service area. Roaming expenses as a percentage of our total revenues represented 1.4% in 2011, 1.7% in 2012 and 1.4% in 2013.

This type of expense includes primarily the cost of handsets and accessories sold to subscribers, and the cost of SIM cards provided to our customers. Cost of handsets, accessories sold and SIM cards provided to customers as a percentage of our total revenues represented 7.5% in 2011, 6.6% in 2012 and 5.7% in 2013. The decrease in 2013 was primarily attributable to the decrease in our handsets sales and our ability to gain significant discounts from our vendors for purchase volumes. We do not subsidize handset sales other than in Ukraine, where we subsidize handsets on a limited basis to contract subscribers as well as modems for CDMA users. In the years ended December 31, 2011, 2012, and 2013 we provided net handset subsidies in Ukraine totaling RUB 257 million, RUB 168 million, and RUB 120 million, respectively.

Generally, we provide SIM cards to our customers free of charge. The cost of SIM cards amounted to RUB 284 million in 2011, RUB 252 million in 2012 and RUB 250 million in 2013.

Sales and marketing expenses reflect, among other things, advertising, promotions and other costs associated with the expansion of services in our license areas. These expenses have generally increased in prior years as subscriber numbers, market saturation and market competition have increased, as well as in connection with the further development of our brand and introduction of new value-added services. In 2012, we changed the motivation scheme for our dealers, shifting from a fixed bonus per acquired subscriber to a bonus depending on the subscriber quality which is measured by a percentage of subscriber payment. This resulted in the decrease of sales and marketing expenses in 2012. In 2013, sales and marketing expenses remained generally stable and we expect them to remain stable.

At the same time, we retain some degree of flexibility to increase or decrease these expenses in any given period based on our requirements, strategy and the general economic environment. For the structure of our dealer commissions in Russia and Ukraine please see "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Sales and Marketing—Sales and Distribution."

Sundry operating expenses as a percentage of our total revenues represented 22.5% in 2011, 22.9% in 2012 and 23.6% in 2013. The increase in 2013 is mainly attributable to increase in salaries and social contributions resulting from increasing number of employees (mainly leading from our continuing retail expansion) and salary indexation. In addition, rent expenses grew as a result of inflation and increasing number in base station sites rented. Sundry operating expenses as a percentage of revenue are expected to increase over time as a result of inflation.

Depreciation of Property, Network Equipment and Amortization of Intangible Assets

Our expense for depreciation of property, network equipment and amortization of intangible assets as a percentage of our total revenues increased to 18.4% for the year ended December 31, 2013 as compared to 18.0% of our total revenues for the year ended December 31, 2012. This increase was due to our increased asset base resulting from the continued expansion of our network through build-outs, as well as due to accelerated depreciation of certain equipment. We expect further increases in connection with our ongoing network development and modernization program and the build-out associated with our regional networks.

Our interest expense for 2013 decreased by RUB 2,175 million or 12.3% compared to 2012 and amounted to RUB 15,498 million. The decrease is primarily attributable to the decline in our total indebtedness, revision of interest rates during 2013 as well as raising funds at lower interest rates. We do not expect interest expense to increase in 2014.

Taxation on income of Russian companies is regulated by a number of laws, government decrees and implementation instructions.

The income tax base for Russian companies is defined as income received from sales of goods and services reduced by the amount of business expenses incurred in such operations with certain exceptions.

The statutory income tax rate in Russia is 20%. Effective April 1, 2011, the statutory income tax rate in Ukraine was reduced from 25% to 23%, to 21% in 2012, to 19% in 2013 and will decrease to 18% in 2014, to 17% in 2015 and to 16% in 2016. The effective tax rate applicable to our consolidated group in the year ended December 31, 2013 was 20.3%. The effective tax rate differs from the statutory rate insignificantly, mainly as a result of earnings distributions from subsidiaries, effect of the lower tax rates of subsidiaries and other items not liable for tax purposes.

Beginning with the period commencing on January 1, 2013, we changed our reporting currency from U.S. dollar to Russian Ruble. Previously, we had presented our consolidated financial statements in U.S. Dollars. Our change in reporting currency is to allow better transparency of reporting.

A majority of our capital expenditure and a significant part of our liabilities and borrowings are either denominated in or tightly linked to the U.S. dollar or euro. We conduct our operations within the Russian Federation, Ukraine, Turkmenistan and Armenia, and we are therefore subject to currency fluctuations. The local currencies of these countries fluctuate significantly against the U.S. dollar and euro. As a result of these fluctuations we may incur significant currency exchange gains/losses which may adversely affect our net income.

Our financial position and results of operations as reflected in our audited consolidated financial statements included elsewhere in this document have been influenced by inflation.

The Ukrainian economy has typically been characterized by high rates of inflation until 2012:

Inflation rates in Armenia and Turkmenistan in 2013 were estimated at 5.6% and 6.0% respectively.

We expect inflation-driven increases in costs to put pressure on our margins. While we could seek to raise our tariffs to compensate for such increase in costs, competitive pressures may not permit increases that are sufficient to preserve operating margins. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Inflation could increase our costs and adversely affect our results of operations."

Our results of operations for the periods presented are significantly affected by acquisitions. Except for Metro-Telecom and Sistema Telecom acquired from Sistema, results of operations of acquired businesses are included in our audited consolidated financial statements for the periods after their respective dates of acquisition. See "Item 3. Key Information—A. Selected Financial Data."

Consolidated revenues for the year ended December 31, 2013, increased by RUB 20,203 million, or 5.3%, to RUB 398,443 million from RUB 378,240 million for the year ended December 31, 2012. The principal reason for the growth of our consolidated revenues for the year ended December 31, 2013, was the large increase in the usage of value-added services by our subscribers (by RUB 14,860 million), which was mainly attributable to the increase of data traffic driven by our active promotion of value-added services, an increase in mobile Internet penetration, an increase in usage of smartphones by our subscribers and active 3G network expansion and the consequent improvement of the quality and uptake of value-added services. The increase of our consolidated revenues for the year ended December 31, 2013 was also supported by the growth of interconnect revenues by RUB 1,206 million, increases in roaming revenues by RUB 1,663 million and a growth in fixed line revenues by RUB 2,838 million. The growth of our interconnect revenues was due to increases in the volume of traffic from our competitors. The increase in roaming revenues was attributable to increases in the volume of traffic from our subscribers resulting from the launch of attractive roaming propositions. The increase in fixed line revenues was mainly attributable to the growth of revenues from fixed line Internet and TV due to the development of the GPON project and consequent improvement in quality and uptake of services provided. In the year ended December 31, 2013, we experienced a decline in our revenues from sales of handsets and accessories by RUB 2,409 million due to refocusing of our devices strategy to promote sales of affordable smartphones. Our consolidated mobile subscriber base, excluding Uzbekistan increased and amounted to 102.4 million as of December 31, 2013 as compared to 95.5 million as of December 31, 2012. The decrease in the mobile churn rate in Russia to 36.3% from 42.4% in 2012 had an immaterial impact on our consolidated revenues.

Consolidated cost of services and cost of handsets and accessories for the year ended December 31, 2013 decreased slightly and amounted to RUB 106,413 million as compared to RUB 108,093 million for the year ended December 31, 2012 and comprised 26.7% and 28.6% as a percentage of consolidated revenues for the year ended December 31, 2013 and 2012, respectively. The decline was mainly attributable to the decrease in the cost of handsets and accessories as a percentage of revenue to 5.4% of consolidated revenues for the year ended December 31, 2013 as compared to 6.3% of consolidated revenues for the year ended December 31, 2012 attributable to an increase in the amount of volume discounts offered by our handsets vendors.

Russia revenues for the year ended December 31, 2013, increased by 5.0% to RUB 354,894 million from RUB 337,949 million for the year ended December 31, 2012. The increase in Russia revenues in the year ended December 31, 2013, was primarily due to the growth of revenues from value-added services by RUB 13,366 million, interconnect revenues by RUB 1,808 million, roaming revenues by RUB 1,614 million and fixed line revenues by RUB 2,528 million. Revenues from value-added services as a percentage of Russia revenues in the year ended December 31, 2013, grew to 23.3% as compared to 20.5% in the year ended December 31, 2012, due to the increase in data traffic volumes attributable to the introduction of new marketing initiatives aimed at stimulating greater usage of value-added services among our subscribers and the overall improvement of quality of these services. Interconnect revenues grew to RUB 38,955 million, as compared to RUB 37,147 million, in the year ended December 31, 2012, due to the growth in the volume of traffic from our competitors. The increase in roaming revenues to RUB 34,193 million for the year ended December 31, 2013 as compared to RUB 32,580 million for the year ended December 31, 2012 was attributable to increased traffic volumes from our subscribers resulting from the launch of attractive roaming propositions. The increase in fixed line revenues to RUB 58,126 million for the year ended December 31, 2013 from RUB 55,598 million for the year ended December 31, 2012 was mainly attributable to the growth of revenues from fixed line Internet and TV due to the development of the GPON project and consequent improvement in quality and uptake of services provided. Interconnect revenues, roaming revenues and fixed line

revenues as a percentage of Russia revenues for the year ended December 31, 2013 remained stable and amounted to 11.0%, 9.6% and 16.4% , respectively as compared to 11.0%, 9.6% and 16.5%, respectively for the year ended December 31, 2012. In the year ended December 31, 2013, we experienced a decline in our revenues from the sales of handsets and accessories as a percentage of Russia revenues to 7.4% of Russia revenues in the year ended December 31, 2013 as compared to 8.5% for the year ended December 31, 2012 due to refocusing of our retail strategy to promote affordable smartphones.

Russia cost of services and cost of handsets and accessories for the year ended December 31, 2013, decreased by 1.5% to RUB 99,201 million from RUB 100,725 million for the year ended December 31, 2012. The decline was primarily attributable to the decrease in cost of handsets and accessories by RUB 2,421 million and as a percentage of Russia revenues to 5.9% of Russia revenues in the year ended December 31, 2013 from 6.9% in the year ended December 31, 2012 attributable to a decrease in sales of handsets and accessories and an increase in the amount of volume discounts offered by our handsets vendors.

Ukraine revenues increased by 5.3% to RUB 39,732 million in the year ended December 31, 2013, from RUB 37,722 million in the year ended December 31, 2012, primarily due to the growth in usage of value-added services by our subscribers, an increase in interconnect revenues and the increase in the number of our subscribers by 9.6% to 22.7 million from 20.7 million. Value-added services revenues increased by 8.8% to RUB 12,088 million in the year ended December 31, 2013, from RUB 11,114 million in the year ended December 31, 2012, due to the active promotion of these services among our subscribers. Value-added services revenues as a percentage of Ukraine revenues in the year ended December 31, 2013, grew to 30.4%, as compared to 29.5% in the year ended December 31, 2012. An increase in interconnect revenues by RUB 699 million to 18.9% as a percentage of Ukraine revenues for the year ended December 31, 2013 as compared to 18.1% for the year ended December 31, 2012 is attributable to the increase in traffic volume from our competitors. The increase in air time revenue by RUB 492 million arose from the growth of our Ukraine subscriber base by 9.6%.

Ukraine cost of services and cost of handsets and accessories increased insignificantly by 3.9% to RUB 10,067 million in the year ended December 31, 2013, from RUB 9,691 million in the year ended December 31, 2012. Ukraine cost of services and cost of handsets and accessories as a percentage of Ukraine revenues for the year ended December 31, 2013 remained relatively stable and amounted to 25.3% as compared to 25.7% for the year ended December 31, 2012. The moderate growth was primarily attributable to the increase in interconnect expenses by RUB 302 million and an increase in other direct costs by RUB 216 million due to the growth in overall volume of outgoing traffic.

Other countries and business activities revenues for the year ended December 31, 2013, increased by 43.0% to RUB 4,600 million from RUB 3,291 million for the year ended December 31, 2012. The increase was caused by us resuming mobile telecommunications services in Turkmenistan in the second half of 2012. The subscriber base in Turkmenistan as of December 31, 2013 increased to 2.0 million as compared to 1.4 million as of December 31, 2012.

Other countries and business activities cost of services and cost of handsets and accessories for the year ended December 31, 2013, increased to RUB 2,234 million from RUB 1,400 million for the year ended December 31, 2012. The decline was caused by us resuming mobile telecommunications services in Turkmenistan in the second half of 2012.

Consolidated sundry operating expenses for the year ended December 31, 2013, increased by 8.5% to RUB 94,158 million from RUB 86,776 million for the year ended December 31, 2012. Sundry operating expenses as a percentage of our total revenues increased to 23.6% in the year ended December 31, 2013, from 22.9% in the year ended December 31, 2012. The change was mainly attributable to the

increase in salary expenses and related social contributions by RUB 5,304 million amounting to 11.5% of our revenues for the year ended December 31, 2013 compared to 10.7% for the year ended December 31, 2012 due to increases in the number of employees (mainly resulting from our continuing retail expansion), as well as indexation of salaries. In addition, our rent expenses grew due to increases in the number of rented base station sites as well as retail expansion. Rent expenses as a percentage of our total revenues grew to 3.7% for the year ended December 31, 2013, from 3.5% for the year ended December 31, 2012. The increase was also attributable to the increase of taxes other than income tax to 1.6% of our total revenues for the year ended December 31, 2013 from 1.4% for the year ended December 31, 2012.

Russia sundry operating expenses for the year ended December 31, 2013, increased by 11.1% to RUB 78,639 million from RUB 70,754 million for the year ended December 31, 2012. Russia sundry operating expenses as a percentage of Russia revenues increased to 22.2% for the year ended December 31, 2013, from 20.9% for the year ended December 31, 2012. The increase of Russia sundry operating expenses as a percentage of Russia revenues was mainly attributable to the increase in the percentage of salary expenses and related social contributions to 10.4% for the year ended December 31, 2013, from 9.3% for the year ended December 31, 2012 due to increases in the number of employees and salary indexation. Rent expenses grew to 3.6% of our Russia revenues for the year ended December 31, 2013, from 3.4% for the year ended December 31, 2012, attributable to an increase in the number of rented base station sites and retail expansion. Taxes other than income as a percentage of Russia revenues increased to 1.6% of our Russia revenues for the year ended December 31, 2013 from 1.4% for the year ended December 31, 2012.

Ukraine sundry operating expenses for the year ended December 31, 2013, increased by 1.9% to RUB 6,360 million from RUB 6,243 million for the year ended December 31, 2012. Ukraine sundry operating expenses as a percentage of Ukraine revenues decreased to 16.0% for the year ended December 31, 2013, from 16.6% for the year ended December 31, 2012. The increase in sundry operating expenses was primarily attributable to the increase in salary expenses and related social contributions and rent.

Other countries and business activities sundry operating expenses for the year ended December 31, 2013, decreased by 6.6% to RUB 9,050 million from RUB 9,687 million for the year ended December 31, 2012. Other countries and business activities sundry operating expenses as a percentage of other countries and business activities revenues decreased to 99.1% for the year ended December 31, 2013, from 151.8% for the year ended December 31, 2012. This decrease was mainly due to the recognition of a one off operating gain resulting from the settlement of the Bitel litigation amounting to RUB 1,060 million.

Consolidated sales and marketing expenses for the year ended December 31, 2013, increased by 5.5%, or RUB 1,194 million, to RUB 22,861 million from RUB 21,667million for the year ended December 31, 2012. This increase was mainly attributable to the increase in commissions payable to dealers by RUB 639.1 million. Dealer commissions as a percentage of our revenues remained stable at 3.6% for the year ended December 31, 2013 compared to 3.6% for the year ended December 31, 2012. This resulted from the fact that in 2012 we introduced changes into the motivation scheme for our dealers shifting from a fixed bonus per acquired subscriber to a bonus depending on the subscriber quality, which is measured by a percentage of subscriber payment and this scheme remained in place in 2013. Advertising and promotion expenses increased by 7%, or RUB 554.7 million, to RUB 8,463 million for the year ended December 31, 2013, from RUB 7,908 million for the year ended December 31, 2012, which was primarily attributable to our marketing efforts. Sales and marketing expenses as a percentage of our total revenues remained stable at 2.1% for the year ended December 31, 2013 and 2012.

Russia sales and marketing expenses for the year ended December 31, 2013, increased to RUB 19,356 million, or 5.5% of Russia revenue, from RUB 18,462 million, or 5.5% of Russia revenues, for the year ended December 31, 2012. The increase in sales and marketing expenses by 4.8% was due to the increase of dealer commissions by RUB 440.5 million and advertising and marketing expenses by RUB 453.0 million.

Ukraine operating income for the year ended December 31, 2012, increased by 62.3% to RUB 9,647 million from RUB 5,946 million for the year ended December 31, 2011. Ukraine operating income increased as a percentage of Ukraine revenues to 25.6% for the year ended December 31, 2012, from 17.6% for the year ended December 31, 2011. These increases were largely due to the growth in Ukraine revenues by 11.9% and the simultaneous decline of depreciation and amortization expenses as a percentage of Ukraine revenues to 25.4% for the year ended December 31, 2012 from 30.2% for the year ended December 31, 2011 due to the reasons described above.

Other countries and business activities operating loss for the year ended December 31, 2012, increased by RUB 410 million to RUB 7,626 million from RUB 7,216 for the year ended December 31, 2011. The increase was caused by resumption of our operations in Turkmenistan in the second half of 2012 and by the decline of other countries and business activities depreciation and amortization expenses both in absolute terms and as a percentage of other countries and business activities revenues due to the reasons described above.

Consolidated currency exchange and transaction gains for the year ended December 31, 2012, was RUB 3,952 million, compared to the loss of RUB 4,403 million for the year ended December 31, 2011. We conduct our operations within the Russian Federation, Ukraine, Turkmenistan and Armenia, and we are therefore subject to currency fluctuations. The local currencies of these countries fluctuated significantly against the U.S. dollar and euro during the years ended December 31, 2012 and 2011, and the currency exchange and transaction gains/losses we incurred were primarily due to the translation effect of our U.S. dollar and euro-denominated debt as of December 31, 2012 and 2011. The gains recognized in 2011 as compared to losses recorded in 2011 were mainly due to the appreciation of the Russian ruble against the U.S. dollar and euro during the year ended December 31, 2012, as compared to 2011.

Consolidated interest expense for the year ended December 31, 2012, decreased by RUB 1,660 million, or 8.6%, to RUB 17,673 million from RUB 19,333 million for the year ended December 31, 2011. The decrease was mainly due to decrease of our weighted average interest rate (6.9% as of December 31, 2012 against 7.6% as of December 31, 2011) resulting from revision of coupon rate for

MTS Notes due 2016 and drawing of funds under credit facility of Calyon, ING N.V. Nordea Bank AB, Reiffeisen Zentralbank Osterreich AG, which bears relatively lower interest rate in comparison to RUB denominated notes and loans as well as decline in our average debt balance.

Consolidated equity in net income of associates for the year ended December 31, 2012, decreased by RUB 561 million, or 39.2%, to a gain of RUB 869 million, compared to a gain of RUB 1,430 million for the year ended December 31, 2011. The decline is attributable to the depreciation of the Belarusian ruble against the U.S. dollar and subsequent decline in income of our equity investee in Belarus during the year ended December 31, 2012.

Consolidated other expenses for the year ended December 31, 2012, increased to RUB 687 million, as compared to RUB 181 million for the year ended December 31, 2011. This increase was primarily attributable to the growth of expenses relating to the dispute with Nomihold and an increase in loss from currency sale in the year ended December 31, 2012, as described in Note 16 to our consolidated financial statements.

Consolidated provision for income taxes for the year ended December 31, 2012, increased by 24.9% to RUB 19,384 million from RUB 15,526 million for the year ended December 31, 2011. The effective tax rate decreased to 23.4% in the year ended December 31, 2012, from 26.0% in the year ended December 31, 2011 mainly as a result of decrease in earnings distributions from subsidiaries and expenses non-deductible for tax purposes.

Net income attributable to the non-controlling interest for the year ended December 31, 2012, amounted to RUB 970 million compared to net income attributable to the non-controlling interest of RUB 3,624 million for the year ended December 31, 2011. The decline in net income attributable to the non-controlling interest resulted from the increase of our ownership interest in MGTS during the year ended December 31, 2011, from 51.3% to 94.1%.

Net income attributable to the Group for the year ended December 31, 2012, decreased by RUB 12,674 million, or 30.0%, to RUB 29,642 million, compared to RUB 42,315 million for the year ended December 31, 2011. Net income as a percentage of revenues was 7.8% in the year ended December 31, 2012, and 12.1% in the year ended December 31, 2011. Net income attributable to the Group for the year ended December 31, 2012, as compared to the year ended December 31, 2011, decreased due to the effect of the loss from discontinued operations in Uzbekistan in the amount of RUB 32,846 million recognized in the year ended December 31, 2012. The decrease in net income attributable to the Group was partially offset by the overall increase in revenues by 8.5% with the simultaneous decrease in sales and marketing expenses and depreciation and amortization expenses as a percentage of revenues for the year ended December 31, 2012 as compared to the year ended December 31, 2011.

Our borrowings consist of notes and bank loans. Since 2001, we have raised a total of $3.0 billion (RUB 92.8 billion at the date of transactions) through seven U.S. dollar-denominated unsecured bond

offerings in the international capital markets, as well as ruble-denominated bonds totaling RUB 96 billion. Our bank loans consist of U.S. dollar-, euro- and ruble-denominated borrowings totaling approximately RUB 116.4 billion as of December 31, 2013. We repaid approximately RUB 45,191 million of indebtedness in 2013. As of December 31, 2013, the total amount available to us under our credit facilities amounted to RUB 5.0 billion. We had total indebtedness of approximately RUB 219.1 billion as of December 31, 2013, including capital lease obligations, compared to approximately RUB 232.1 billion as of December 31, 2012. Our total interest expense for the years ended December 31, 2012 and 2013, was RUB 17,673 million and RUB 15,498 million, net of amounts capitalized, respectively. See Note 15 to our audited consolidated financial statements for a description of our indebtedness.

We anticipate that capital expenditures, acquisitions, repayment of long-term debt and dividends will represent the most significant uses of funds for several years to come.

Our cash outlays for capital expenditures in 2011, 2012 and 2013 were RUB 72,802 million, 87,783 million and RUB 81,575 million, respectively. We expect to continue to finance most of our capital expenditure needs through our operating cash flows, and to the extent required, to incur additional indebtedness through borrowings or additional capital raising activities. Historically, a significant portion of our capital expenditures have been related to the installation and build-out of our network and expansion into new license areas. We expect that capital expenditures will remain a large portion of our cash outflows in connection with the continued installation and build-out of our network. We expect our total capital expenditures in 2014 to be approximately 21% of our total 2014 revenue. These investments are required to support the growth in our subscriber base (i.e., to improve network capacity), to maintain and modernize our mobile and fixed line networks, to develop our network in the regions and to continue with the roll out of LTE networks throughout Russia as well as the development of our proprietary retail chain in Russia. We expect that the development of LTE networks will be among our most significant capital expenditures and require considerable management resources. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Services Offered—3G Technology" for additional information. Our actual capital expenditures may vary significantly from our estimates.

In addition to capital expenditures, RUB 33,086 million and RUB 2,198 million (net of cash acquired) in 2011 and 2012, respectively, was spent to acquire businesses. Part of the consideration was paid in connection with our acquisition of Comstar and MGTS. See "Item 3. Key Information—A. Selected Financial Data" and Note 3 to our audited consolidated financial statements. In 2013 we bought a 25.0945% stake in MTS Bank for RUB 5,089 million. We also used cash provided by operating activities as well as external credit facilities to finance our capital expenditures. We plan to finance future acquisitions through operating cash flows and additional borrowings. We may continue to expand our business through acquisitions. Our cash requirements relating to potential acquisitions can vary significantly based on market opportunities.

We expect to refinance our existing debt when it becomes due. Of our notes outstanding as of December 31, 2013, RUB 17,462 million are due in 2014, RUB 22,558 million are due in 2015 and RUB 1,800 million are due in 2016. Of our bank loans outstanding as of December 31, 2013, RUB 7,564 million is due in 2014, RUB 11,669 million is due in 2015 and RUB 26,590 million is due in 2016. We generally use the proceeds from our financing activities for our corporate purposes and refinancing existing indebtedness.

Sistema, which currently controls 51.46% of our total charter capital (53.47% excluding treasury shares) and consolidates our results in its financial statements, has a significant amount of outstanding debt and requires funds for debt service. These funds may come, in part, from dividends paid by its subsidiaries, including us. Our shareholders approved cash dividends in the amount of RUB 30,046 million (including dividends on treasury shares of RUB 1,127 million) for the year 2010, of which RUB 6 million remained payable as of December 31, 2011, RUB 30,397 million (including dividends on treasury shares of RUB 1,140 million) for 2011, of which RUB 4 million remained payable as of December 31, 2012, and RUB 30,168 million (including dividends on treasury shares of RUB 1,131 million) for 2012. In 2013, MTS started to pay out dividends on a semi-annual basis using interim 6 months and full-year financial results as a foundation, and the amount of semi-annual dividends for 2013 approved by our shareholders was RUB 10,786 million (including dividends on treasury shares of RUB 405 million). Dividends payable to our shareholders as of December 31, 2013, amounted to RUB 1 million.

We generally intend to finance our dividend requirements through operating cash flows, and accordingly, our payment of dividends may make us more reliant on external sources of capital to finance our capital expenditures and acquisitions.

We plan to finance our capital requirements through a mix of operating cash flows and financing activities, as described above. Our major sources of cash have been cash provided by operations and the proceeds of our U.S. dollar-denominated and ruble-denominated note issuances and loans. We expect that these sources will continue to be our principal sources of cash in the future.

The availability of financing is influenced by many factors, including our profitability, operating cash flows, debt levels, credit ratings, contractual restrictions and market conditions. We cannot assure you that we will be able to continue to obtain large amounts of financing in the future through debt or equity offerings, bank financings or otherwise.

As of December 31, 2013, our outstanding indebtedness consisted of the following notes and bank loans:

The Group has an unconditional obligation to repurchase certain MTS OJSC Notes at par value if claimed by the noteholders subsequent to the announcement of the sequential coupon. The dates of the announcement for each particular note issue are as follows:

Subject to certain exceptions and qualifications, the indentures governing our U.S. dollar-denominated notes due 2020 contain covenants limiting our ability to incur debt, create liens, sell or transfer lease properties, enter into loan transactions with affiliates, merge or consolidate or convey our properties and assets to another person, as well as our ability to sell or transfer any of our GSM licenses for the Moscow, St. Petersburg, Krasnodar and Ukraine license areas. In addition, if we experience a change in control, noteholders will have the right to require us to redeem the notes at 101% of their principal amount, plus accrued interest. We are required to take all commercially reasonable steps necessary to maintain a rating of the notes from Moody's or Standard & Poor's. We are also prohibited from having any judgment, decree or order for payment of money in an amount $15.0 million (RUB 491 million as of December 31, 2013) for MTS International Notes 2020 and $75.0 million (RUB 2,455 million as of December 31, 2013) for MTS International Notes due 2023 unsatisfied for more than 60 days without being appealed, discharged or waived. If we fail to comply with these and the other covenants contained in the indentures, after certain notice and cure periods, the noteholders can accelerate the debt to be immediately due and payable.

Our ruble-denominated notes contain certain covenants limiting our ability to delist the notes from the quotation lists and delay coupon payments. We may from time to time seek to repurchase or redeem our outstanding notes through cash purchases and/or exchanges for new debt securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on market conditions, our liquidity requirements, contractual restrictions and other factors.

Our loans are subject to certain restrictive covenants, including, but not limited to, negative pledges, certain financial ratios, limitations on dispositions of assets and limitations on transactions with associates, requirements to maintain ownership in certain subsidiaries, maintain certain contracts or licenses, maintain assets of certain value and to maintain a certain level of deposits in accounts at our creditor banks. In addition, there are restrictions on the granting of loans and guarantees and the incurrence of debt the purpose of which is to facilitate us paying or making any dividend or other payment or distribution of any kind on or in respect of any of our shares or to undertake any form of capital reduction. Most of the loans also include an event of default involving an unsatisfied judgment against us in excess of $10.0 million (RUB 327 million as of December 31, 2013) for a period of over 60 consecutive calendar days. We were in compliance with our loan covenants as of December 31, 2013.

The following table presents the aggregate scheduled maturities of debt principal outstanding as of December 31, 2013:

In addition, we had capital lease obligations in the amount of RUB 48 million and RUB 212 million as of December 31, 2013 and 2012, respectively. The terms of our material debt obligations are described in Note 15 to our audited consolidated financial statements.

Subsequent to December 31, 2013, we repaid approximately RUB 2,608 million (based on USD and Euro exchange rates as of the payment dates) in short-term indebtedness.

In addition, Sistema, which currently controls 51.46% of our total charter capital (53.47% excluding treasury shares) and consolidates our results in its financial statements, is subject to various covenants in certain of its credit facilities which impose restrictions on Sistema and its restricted subsidiaries, including us, with respect to, among others, incurrence of indebtedness and liens. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Indentures relating to some of our notes contain, and some of our loan agreements and Sistema's loan agreements contain, restrictive covenants, which limit our ability to incur debt and to engage in various activities."

Cash payments for the acquisition of subsidiaries from related party and non-controlling interests		(26,517	)		(261	)		—

For the year ended December 31, 2013, net cash provided by operating activities from continuing operations was RUB 159,924 million, an increase of 18.6% from the year ended December 31, 2012. This increase was primarily attributable to an increase in total revenues due to the increased usage of value added services by our subscribers as well as one off cash inflow recognized on settlement of Bitel litigation in amount of RUB 4,093 million.

Net cash from continuing operations used in investing activities in the year ended December 31, 2013 was RUB 96,786 million, an increase of 6.0% from the year ended December 31, 2012. Net cash used on purchases of property, plant and equipment and intangible assets in the year ended December 31, 2013, decreased by RUB 6,208 million. The cash outflow relating to short term and other investments in the form of deposits and loans increased by RUB 8,544 million. The amount of cash paid for acquisition of subsidiaries, net of cash acquired, decreased by RUB 1,937 million. At the same time investments in associates increased by RUB 5,088 million due to acquisition of 25.0945% stake in MTS Bank.

Net cash from continuing operations used in financing activities in the year ended December 31, 2013 was RUB 55,145 million, compared to RUB 75,346 million used in the year ended December 31, 2012. The decrease was mainly attributable to our repayments of loans and debt, which were by RUB 17,764 million lower than in 2013. In addition, the amount of funds raised by us in the year ended December 31, 2013 increased by RUB 8,049 million, as compared to the year ended December 31, 2012. The effect of change in cash flows related to debt activities was partially offset by an increase in dividends paid (by RUB 10,080 million) resulting from change in our dividend policy (starting from 2013 we pay dividends on a semi-annual basis). Additional cash inflows were generated from the sale of MGTS's subsidiary—"Business Real Estate"—to AFK Sistema for RUB 3,215 million (RUB 3,068 million net of cash disposed), as well as reimbursement of debt issuance costs paid for insurance premium of not used credit facilities in amount of RUB 959 million.

For the year ended December 31, 2012, net cash from continuing operations provided by operating activities was RUB 134,856 million, an increase of 26.0% from the year ended December 31, 2011. This increase was primarily attributable to an increase in total revenues due to the increased usage of value added services by our subscribers.

Net cash from continuing operations used in investing activities in the year ended December 31, 2012 was RUB 91,322 million, an increase of 25.7% from the year ended December 31, 2011. Net cash used on purchases of property, plant and equipment and intangible assets in the year ended December 31, 2012, increased by RUB 14,981 million. The cash outflow relating to short term and other investments in the form of deposits and loans increased by RUB 7,957 million. The amount of cash paid for acquisition of subsidiaries, net of cash acquired, decreased by RUB 4,632 million.

Net cash used in financing activities in the year ended December 31, 2012 was RUB 75,346 million, compared to RUB 5,630 million used in the year ended December 31, 2011. The increase was mainly attributable to our repayments of loans and debt, which were by RUB 52,915 million greater than in 2011 (of which RUB 29,200 million was due to the voluntary early repayment of Gazprombank and Moscow Bank facilities. In addition, the amount of funds raised by us in the year ended December 31, 2012 decreased by RUB 50,220 million, as compared to the year ended December 31, 2011. The effect of change in cash flows related to debt activities was partially offset by decrease in cash payments for acquisitions of subsidiaries from related parties and non-controlling interests (by RUB 26,256 million), dividends paid (by RUB 5,157 million) and notes and debt issuance costs (by RUB 2,171 million).

As of December 31, 2013, we had total cash and cash equivalents of RUB 30,612 million (RUB 20,115 million in rubles, RUB 8,839 million in U.S. dollars, RUB 697 million in Turkmenistan

manat, RUB 531 million in euros, RUB 363 million in Ukrainian hryvnias, RUB 67 million in Armenian dram). In addition, as of December 31, 2013, we had short-term investments of RUB 14,633 million, mostly in deposits in various banks as well as money market funds. We also had RUB 5,000 million available under existing credit facilities as of December 31, 2013. For a description of our outstanding external financing, see Note 15 to our audited consolidated financial statements.

As of December 31, 2013, we had a working capital surplus of RUB 14,814 million compared to a deficit of RUB 21,043 million as of December 31, 2012. The increase in working capital was mainly attributable to an increase in our total cash and cash equivalents by RUB 8,598 million, in short term investments by RUB 10,599 million, in trade receivables by RUB 1,182 million as well as in other assets by RUB 1,317 million and the decrease in accrued liabilities and other payables by RUB 12,981 million (of which RUB 8,031 related to provision for claims in Uzbekistan and RUB 6,718 related to the Bitel liability). We expect to repay all long-term debts as they become due from our operating cash flows or through re-financings. We believe that our working capital, together with our plans for external financing, will provide us with sufficient funds for our present requirements.

Russian law requires that dividends can only be paid in an amount not exceeding net profits as determined under Russian accounting standards, denominated in rubles, after certain deductions. In addition, dividends may only be paid if the value of the company's net assets is not less than the sum of the company's charter capital, the company's reserve fund and the difference between the liquidation value and the par value of the issued and outstanding preferred stock of the company, if any, as determined under Russian accounting standards. Our net income under Russian accounting standards for the years ended December 31, 2011, 2012 and 2013 that was distributable under Russian legislation amounted to RUB 54,129 million, RUB 42,949 and RUB 55,999 million, respectively.

Our credit ratings impact our ability to obtain short- and long-term financing, and the cost of such financing, and credit rating downgrades may require us to prepay certain loans. In determining our credit ratings, the rating agencies consider a number of factors, including our operating cash flows, total debt outstanding, commitments, interest requirements, liquidity needs and availability of liquidity. Other factors considered may include our business strategy, the condition of our industry and our position within the industry and the strategy, activity and/or credit rating of Sistema. Although we understand that these and other factors are among those considered by the rating agencies, each agency might calculate and weigh each factor differently. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Our controlling shareholder has the ability to take actions that may conflict with the interests of holders of our securities."

Our significant accounting policies are disclosed in Note 2 to our audited consolidated financial statements. Critical accounting policies are those policies that require the application of management's most challenging, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. Critical accounting policies involve judgments and uncertainties that are sufficiently sensitive to result in materially different results under different assumptions and conditions. We believe our most critical accounting policies and estimates are those discussed below.

The preparation of our audited consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements

and the reported amounts of revenues and expenses for the reporting period. Actual results could differ from those estimates. Our significant estimates include the allowance for doubtful accounts, allowance for inventory obsolescence, valuation of assets acquired and liabilities assumed in business combinations, income tax benefits, the recoverability of goodwill, intangible assets and other long-lived assets, certain accrued liabilities and valuation of financial instruments.

We calculate depreciation expense for property, plant and equipment on a straight-line basis over their estimated useful lives. We establish useful lives for each category of property, plant and equipment based on our assessment of the use of the assets and anticipated technology evolution. We review and revise if appropriate the assumptions used in the determination of useful lives of property, plant and equipment at least on an annual basis. With regard to certain equipment, we cannot predict with certainty how and when developing technology will require us to replace such equipment.

We periodically evaluate the recoverability of the carrying amount of our long-lived assets. Whenever events or changes in circumstances indicate that the carrying amounts of those assets may not be recoverable, we compare undiscounted net cash flows estimated to be generated by those assets to the carrying amount of those assets. When these undiscounted cash flows are less than the carrying amounts of the assets, we record impairment losses to write the asset down to fair value, measured by the estimated discounted net future cash flows expected to be generated from the use of the assets. None of the Group's long-lived assets were impaired in 2013. An impairment loss in the amount of RUB 16,514 million for the year ended December 31, 2012 was recognized by our subsidiaries in Uzbekistan and included net loss from discontinued operations. See also Note 2 and Note 4 to our audited consolidated financial statements.

Goodwill represents an excess of the consideration paid over the fair market value of net identifiable assets acquired in a purchase business combination and is not amortized. Goodwill is reviewed for impairment at least annually or whenever it is determined that one or more impairment indicators exist. We determine whether impairment has occurred by assigning goodwill to the reporting unit identified in accordance with the authoritative guidance on intangibles, and comparing the carrying amount of the reporting unit to the fair value of the reporting unit. If an impairment of goodwill has occurred, we recognize a loss for the difference between the carrying amount and the implied fair value of goodwill. As of December 31, 2012, we recognized goodwill impairment in the amount of RUB 3,523 million related to Uzdunrobita Litigation, which is included in the net loss from discontinued operations. Please see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" regarding the recent suspension of our services in Uzbekistan, "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Uzbekistan" and Note 4 to our audited consolidated financial statements.

Generally, tax declarations remain open and subject to inspection for a period of three years following the tax year. While most of our tax declarations have been inspected without significant penalties, these inspections do not eliminate the possibility of re-inspection.

We believe that we have adequately provided for tax liabilities in our financial statements; however, the risk remains that relevant authorities could take differing positions with regard to interpretive issues and the effect could be significant. See Note 27 to our audited consolidated financial statements.

We recognize deferred tax assets and liabilities for the expected future tax consequences of existing differences between financial reporting and tax reporting bases of assets and liabilities, and for the loss or tax credit carry-forwards using enacted tax rates expected to be in effect at the time these differences are realized. We record valuation allowances for deferred tax assets when it is likely that these assets will not be realized.

In July 2012, the FASB updated the authoritative guidance on testing indefinite-lived intangible assets for impairment. The update permits the entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. The guidance is effective for all entities for annual and interim goodwill impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this guidance did not have a significant impact on our consolidated financial statements.

In March 2013, the FASB issued the authoritative guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or group of assets within a foreign entity or of an investment in a foreign entity. This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance is effective for fiscal years and interim reporting periods within those fiscal years beginning after December 15, 2013. The amendments described in the update are to be applied prospectively to derecognition events occurring after the effective date; prior periods are not to be adjusted. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In 2013, our revenues in Russia and Ukraine increased by 5% and 5.3%, respectively. Our mobile subscriber base increased to 95.5 million subscribers from 95.5 million subscribers as of December 31, 2013. We expect our consolidated subscriber base to grow in 2013 as a result of continued marketing and advertising activity. We anticipate our consolidated revenues will increase in 2013 mainly based on growth in data usage and the development of our broadband business in the regions.

Average monthly service revenue per subscriber in Russia increased to RUB 307.9 for the year ended December 31, 2013, from RUB 297.1 for the year ended December 31, 2012. Average monthly minutes of use per subscriber in Russia increased to 327 minutes in 2013 from 304 minutes in 2012 mainly due to decrease in tariffs for on-net traffic and various roaming-related offers. We expect average monthly service revenue per subscriber in Russia to remain stable in 2014 as we plan to decrease prices and stimulate growth in usage of data services. We also believe that average monthly

minutes of use per subscriber will remain stable with an increase in megabytes of use per subscriber due to our efforts aimed at stimulating data usage and on-net traffic.

In Ukraine, our subscriber base increased to approximately 22.7 million subscribers as of December 31, 2013, from 20.7 million subscribers as of December 31, 2012. While APPM remained stable in 2013, our ARPU stagnation and MOU reduction have been caused by the growth in low value subscribers. In 2014, we expect revenues to remain stable under the impact of the weaker macroeconomic environment. We expect the average monthly minutes of use per subscriber will remain stable or decrease slightly in 2014. We expect MTS Ukraine's subscriber base to increase in 2014 due to continued development and marketing of our best customer experience in order to position ourselves as an operator with the optimum price/quality proposition of voice and data services.

Our subscriber base in Armenia remained stable and amounted to 2.4 million subscribers in 2013. The average monthly service revenue per subscriber in Armenia increased to 2,737 dram (RUB 213.2) from 2,656 dram (RUB 205.6). We expect the average monthly service revenue per subscriber in Armenia to decline mainly due to the growth of competition on these markets which may, in turn, lead to decreasing tariffs, the addition of lower-value mass market subscribers, as well as increasing market penetration and multiple SIM card usage per person.

Our primary operating license in Turkmenistan was resumed, and all of our operations in the country fully recommenced on October 1, 2012. Our subscriber base in Turkmenistan amounted to approximately 2.0 million subscribers as of December 31, 2013. We expect our subscriber base and revenues to increase and our market share to grow in 2014.

Russia and Ukraine are the two largest markets for us, both in terms of subscribers and revenue. In 2013, the underlying developments within these markets remained generally positive and included high mobile penetration, strong demand for mobile services, generally positive usage trends and increased consumption of data services and value-added services. We expect the growth of our business activity in Russia to continue throughout 2014. We also expect that the stabilizing of the political situation in Ukraine will allow us to retain our operating indicators.

We expect a challenging operating environment in 2014 due to continued macroeconomic and market volatility in the countries where we operate, increasing competition and significant changes in the mobile retail market in Russia. We also experienced significant exchange rate volatility and depreciation of local currencies against the U.S. dollar in the countries where we operate. The volatility and devaluation of local currencies against the U.S. dollar and/or euro may adversely affect our revenues reported in U.S. dollars and increase our costs, including our non-cash foreign exchange loss due to the translation of our U.S. dollar- and euro- denominated debt. For further information on these risks, see "—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Currency Fluctuations," and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Inflation could increase our costs and adversely affect our results of operations."

However, considering current macroeconomic conditions, our management believes that we will experience medium- and long-term growth and efficiency. Due to the fact that the Russian and the Ukrainian markets are highly penetrated, we believe the next wave of revenue growth for the overall market is likely to come from customers' increasing use of data, content and other value-added services.

We define churn as the total number of subscribers who cease to be a subscriber during the period (whether involuntarily due to non-payment or voluntarily), expressed as a percentage of the average number of our subscribers during that period.

A vast majority of our subscribers are prepaid subscribers with no contractual commitment to us. As a result, these subscribers have unfettered freedom to migrate between operators at their convenience. This freedom, combined with the relative ease with which subscribers can obtain SIM cards, contributes to churn and increasing penetration levels in the markets where we operate.

The churn rate is highly dependent on competition in our license areas and those subscribers who migrate as a result of such competition. Our churn rate in Russia decreased to 36.3% during the year ended December 31, 2013, as compared to 42.4% for the year ended December 31, 2012, as we improved the quality of customer service by developing our proprietary mono-brand retail network in Russia and revised the pattern of interaction with dealers. In addition, we continued to offer our popular tariff plan "Super MTS" (free calls to all subscribers of MTS Russia), updated options for unlimited mobile Internet, further improved network quality and enhanced data rate by expanding our 3G and LTE capabilities. We expect that the extension of the MTS-Bonus loyalty program and further development of our mono-brand retail network will allow us to keep churn rate under control in 2014, stimulate value-added services usage and promote subscriber loyalty through superior customer service.

The churn rate in Ukraine decreased to 26.1% for the year ended December 31, 2013, from 30.5% for the year ended December 31, 2012. This decrease was achieved by adjusting our tariffs in response to changes in the market and economic environment and focusing on subscriber base management.

We believe that our existing off-balance sheet arrangements do not have and are not reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

In 2007, 2008 and 2009 we entered into variable-to-fixed interest rate swap agreements to manage the exposure to changes in variable interest rate related to debt obligations. The instruments qualify for cash flow hedge accounting under U.S. GAAP requirements. Each interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective hedges. Interest rate swap contracts outstanding as of December 31, 2013, mature in 2014-2015.

In 2013, 2012 and 2009, we entered into several cross-currency interest rate swap agreements with various banks. These contracts hedge the risk of both interest rate and currency fluctuations and assume periodical exchanges of both principal and interest payments from ruble-denominated amounts to U.S. dollar- and euro-denominated amounts to be exchanged at a specified rate. The rate was determined by the market spot rate upon issuance. These contracts also include an interest rate swap of a fixed U.S. dollar- and euro-denominated interest rate to a fixed ruble-denominated interest rate. The instruments qualify for cash flow hedge accounting under the U.S. GAAP requirements. Each cross-currency interest swap matches the interest and principal payments of the underlying debt allowing for highly effective hedges. Our cross-currency interest rate swap contracts outstanding as of December 31, 2013, mature in 2019 and 2020.

We have various contractual obligations and commercial commitments to make future payments, including debt agreements, capital lease obligations (including interest) and certain committed

obligations. The following table summarizes our future obligations under these contracts due by the periods indicated as of December 31, 2013:

	Payments due by period

Bonuses are awarded annually based on our financial performance.

Our management and directors are also entitled to monetary remuneration based on the quoted prices of our ADSs on the NYSE. Related compensation accrued in 2013 amounted to RUB 482 million. For additional information, see Note 2 to our audited consolidated financial statements.

In 2009, we amended our Regulation on Remuneration and Compensation of the Members of the Board of Directors to provide that only independent non-executive directors receive compensation. Members of the Board of Directors who are independent non-executive directors receive annual base compensation of $250,000 (RUB 8 million) (or $275,000 (RUB 9 million) in the case of an independent non-executive director who serves as Chairman of the Board of Directors).

Independent non-executive directors who also serve on Board committees receive additional compensation as follows. Members of the Strategy Committee, Remuneration and Nomination Committee, Audit Committee and Committee for Corporate Conduct and Ethics receive additional annual compensation of $15,000 (RUB 0.5 million), and a director serving as Chairman of the foregoing committees receives additional annual compensation of $25,000 (RUB 0.8 million).

The aggregate amount of compensation received by an independent non-executive director (including annual base compensation, bonus and additional compensation for serving as a Board committee member) should not exceed $500,000 (RUB 16 million). In the event of early termination of a director, such director receives a pro rata share of the base, committee and bonus compensation based on the amount of time the director served on our Board.

We provide all of our directors with professional liability insurance and reimburse them for all documented expenses incurred in connection with their attendance at Board meetings and other expenses of up to $200,000 (RUB 7 million).

Members of our Board of Directors are elected by a majority vote of shareholders at the annual shareholders' meeting using a cumulative voting system. Directors are typically elected by the annual meeting of shareholders for one year until the next annual meeting of shareholders and may be re-elected an unlimited number of times. The Joint Stock Companies Law requires that companies with more than 10,000 holders of voting shares have a board of directors consisting of not less than nine members.

In June 2012, the authorities of the Republic of Uzbekistan commenced repeat audits of previously audited financial and operating activities of MTS' wholly owned subsidiary Uzdunrobita. On July 17, 2012, Uzdunrobita suspended its services in Uzbekistan pursuant to the order of the State Agency for Communications and Information of Uzbekistan (the "SACI") temporarily suspending the operating license of Uzdunrobita for a period of ten business days. This suspension was subsequently extended to three months due to a decision of the Tashkent Economic Court of July 30, 2012.

On August 6 and 7, 2012, fourteen regional antimonopoly departments of the Republic of Uzbekistan simultaneously held hearings and declared that Uzdunrobita had violated antimonopoly laws, consumer protection laws and laws governing advertisements. In total, the claims of the regional antimonopoly departments against Uzdunrobita amounted to approximately RUB 2,558 million. This amount was subsequently reduced by the superior antimonopoly regulator to RUB 416 million in the aggregate. The disputes with the antimonopoly authorities were dismissed after payments were made by Uzdunrobita pursuant to the Appeal Decision (as defined below).On August 13, 2012, the Tashkent Economic Court granted the petition of the SACI to terminate all operating licenses of Uzdunrobita permanently. This decision was subsequently upheld by the appeals and cassation instance courts on August 27, 2012 and April 4, 2013, respectively.

Notwithstanding the fact that a tax audit of Uzdunrobita's operations for the period of 2007-2010 was completed in February 2012 and did not reveal any serious violations, further tax audits were conducted and purported to find alleged violations of licensing regulations as well as income and other tax legislation resulting in the imposition of additional taxes and fines totaling approximately RUB 28,776 million. This amount was subsequently reduced to RUB 21,390 million in the aggregate. Whether these taxes and sanctions can be claimed by the Uzbek tax authorities from Uzdunrobita under bankruptcy procedures (discussed below) is uncertain in light of the decisions made by the High Economic Court and the Regional Economic Courts of Appeals between April 4, 2013 and April 11, 2013. With limited exceptions, those decisions dismissed the obligation of the regional tax authorities to enforce the financial sanctions. The decisions, however, do not cover any obligation of the local tax authorities to collect the additional taxes.

During September-October of 2012, RUB 201 million were seized from Uzdunrobita's bank accounts by the Uzbek State and applied to settle a portion of the State's alleged claims.

On September 17, 2012, the Tashkent City Criminal Court issued a ruling in favor of the Uzbek state authorities authorizing the confiscation of all assets of Uzdunrobita based on a criminal court's verdict which the Tashkent City Criminal Court issued against four employees of Uzdunrobita, despite the fact that Uzdunrobita was not itself a party to such proceedings. Prior to this ruling, the Uzbek law enforcement agencies had frozen all of Uzdunrobita's assets, including cash held in local bank accounts.

On November 8, 2012, the Appellate Instance of the Tashkent City Criminal Court allowed Uzdunrobita's appeal challenging the verdict of the Tashkent City Criminal Court dated September 17, 2012. The appeals court found that all damages (taxes, sanctions, unpaid licenses duties and damages to customers) suffered by the State must be compensated by Uzdunrobita. The amount of damages was calculated and determined on the basis of all of the aforementioned claims against Uzdunrobita existing as of November 8, 2012, which amounted to RUB 18,375 million to be paid in eight equal monthly instalments (the "Appeal Decision").

In accordance with applicable Uzbek laws, Uzdunrobita petitioned the Deputy General Prosecutor to challenge the Appeal Decision before the Supreme Court of Uzbekistan and grant a stay of enforcement of the Appeal Decision. Uzdunrobita's petition was rejected by the General Prosecutor's Office on December 25, 2012.

Following this rejection, Uzdunrobita immediately filed a further petition to appeal to the Supreme Court of Uzbekistan with the Chairman of the Supreme Court of Uzbekistan. On January 23, 2013, the Company was notified that the matter had been submitted by the Supreme Court for consideration by the Chairman of the Tashkent City Court. On May 2, 2013, the Chairman of the Tashkent City Court rejected Uzdunrobita's petition.

remaining in Uzdunrobita's bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy with the Tashkent Economic Court due to its inability to meet its further obligations arising out of the Appeal Decision. On January 18, 2013, the Court initiated bankruptcy proceedings and appointed an external temporary supervisor over Uzdunrobita, and scheduled a further bankruptcy hearing which took place on April 22, 2013.

Considering the adverse impact of such circumstances on the Group's ability to conduct operations in Uzbekistan, the Group tested goodwill and other long-lived assets attributable to Uzbekistan for impairment and recorded an impairment charge of RUB 20,037 million in the consolidated statement of operations and comprehensive income for the year ended December 31, 2012.

On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated six-month liquidation procedures which, as far as the Group is able to comprehend, are still in process (the period has been prolonged several times). In accordance with the terms of local liquidation procedures, Uzdunrobita's CEO was relieved of his duties and all of the oversight and governance over Uzdunrobita was transferred to the liquidation administrator. As a result the Group lost control over the subsidiary and deconsolidated Uzdunrobita.

In July 2013, two rounds of auctions were set and held in relation to the sale of assets of Uzdunrobita and all of its branches. All auctions were recognized as having failed due to the absence of any applications by interested bidders.

MTS believes that the claims of the Uzbek state authorities against Uzdunrobita that resulted in the initiation of its bankruptcy are unfounded. The Group reserves all of its rights to pursue all available legal options in Uzbekistan and internationally to defend its legal rights and protect its investments and to fully recover damages or obtain other relief including from any party involved in depriving MTS of its business and assets in Uzbekistan.

MTS has filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes (ICSID), part of the World Bank Group, in Washington, D.C. The claim was registered on November 15, 2012. The tribunal was formed on August 29, 2013 and the first procedural hearings took place in November 2013. The case is currently pending.

For additional information please refer to Note 4 to our audited consolidated financial statements.

In August 2012, the Group received from MTS LLC, a third party based in Ukraine, a claim seeking the dismissal of international registration of four of our trademarks on the territory of Ukraine. The claim was handled by the Economic Court of Kiev, which fully dismissed it in July 2013. MTS LLC appealed the decision of the Economic Court of Kiev, and the appeal was dismissed by Economic Appeal Court of Kiev in December 2013. Please see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Our intellectual property rights are costly and difficult to protect."

In the ordinary course of business, we may be party to various tax proceedings, and subject to tax claims, some of which relate to the developing markets and evolving fiscal and regulatory environments in which we operate. In the opinion of management, our liability, if any, in all pending tax proceedings or tax claims will not have a material effect on our financial condition, results of operations or liquidity. We believe that we have adequately provided for tax liabilities in the accompanying consolidated financial statements; however, the risk remains that relevant authorities could take differing positions with regard to interpretive issues and the effect could be significant. See also Note 27 to our audited consolidated financial statements.

In December 2010, the Russian tax authorities completed a tax audit of MTS OJSC for the years ended December 31, 2007 and 2008. Based on the results of this audit, the Russian tax authorities determined that RUB 353.9 million in additional taxes, penalties and fines were payable by us. The resolution did not come into force as we prepared and filed a petition with the Federal Tax Service to declare the tax authorities' resolution to be invalid. In September 2011, the Federal Tax Service partially satisfied our petition, decreasing the amount of additional taxes, penalties and fines payable by us by RUB 173.9 million. We filed an appeal for RUB 84.2 million of the remaining RUB 180.0 million with the Moscow Arbitrate Court. In August 2013, the Moscow Arbitrate Court issued a ruling to grant our claim partly, which was subsequently confirmed by the Arbitrate Appeal Court in November 2013. However, we appealed the decision of the Arbitrate Appeal Court in the Federal Arbitrate Court of Moscow District, which issued a ruling to partly grant our claim in March 2014. We are considering whether to take further actions.

In February 2012, the Russian tax authorities completed a tax audit of MGTS for the years ended December 31, 2008 and 2009. Based on the results of their audit, the Russian tax authorities assessed RUB 258.1 million in additional taxes, penalties and fines payable by us. In February 2012, MGTS challenged the tax authorities' decision with higher authorities within the Federal Tax Service. In May 2012, the Federal Tax Service refused to satisfy MGTS' claim and MGTS appealed the decision in Moscow Arbitrate Court. The court has ruled in our favor on February 20, 2013, dismissing the Russian tax authorities' claims in their entirety.

In June 2013, the Russian tax authorities completed a tax audit of MTS OJSC for the years ended December 31, 2009, 2010 and 2011. Based on the results of this audit, the Russian tax authorities determined that RUB 253.38 million in additional taxes, penalties and fines were payable by us. In December 2013 we appealed the resolution this assessment to the Federal Tax Service, and, further to its refusal to grant the appeal, we are considering appealing to the Moscow Arbitrate Court.

In January 2014, the Russian tax authorities completed a tax audit of MGTS for the years ended December 31, 2010 and 2011. Based on the results of this audit, the Russian tax authorities determined that RUB 91.0 million in additional taxes and penalties were payable by us. We are considering whether to take further actions.

Generally, according to Russian tax legislation, tax declarations remain open and subject to inspection for a period of three years following the tax year. As of December 31, 2013, the tax declarations of MTS OJSC and its Russian subsidiaries for the preceding three fiscal years were open for further review.

In June 2011, the FAS subdivision in the Republic of Tatarstan determined that we, Vimpelcom, MegaFon and CJSC Smarts violated antimonopoly laws on competition by charging our subscribers higher fees for calls to fixed operators than for calls to other cellular operators. We appealed this decision in the Tatarstan Arbitrate Court, which confirmed the FAS decision in January, 2012. Our further appeals to the Eleventh Arbitrate Appeal Court, Federal Arbitrate Court Povolzhye Region, and Higher Appeal Court of Russia were also not satisfied. In May 2012 FAS subdivision in the Republic of Tatarstan fined us RUB 41.6 million. Our appeals for this penalty were left unsatisfied by decisions of the FAS of Russian Federation in September 2012, the Moscow Arbitrate Court in December 2012, the Ninth Arbitrate Appeal Court in March 2013 and the Federal Arbitrate Court in Moscow Region in August 2013. In April 2013, we fully paid the fine in the amount of RUB 41.6 million.

In October 2011, the FAS subdivision in the Republic of Bashkortostan decided that the agreement on social and economic development in the field of telecommunications between us and the Bashkortostan Ministry of Communications and Mass Media, signed in February 2011, violated

antimonopoly laws on competition as certain provisions of this agreement may constrain competition on the Bashkortostan telecommunications market. In December 2011, we appealed this decision in the Bashkortostan Arbitrate Court, which ruled in our favor in March 2012. However, in March 2012 the FAS subdivision in the Republic of Bashkortostan sought to impose an administrative fine and appealed the decision of the Bashkortostan Arbitrate Court. The Eighteenth Arbitrate Appeal Court in May 2012 and the Federal Arbitrate Court Ural Region in August 2012 also ruled in our favor. Finally, in September 2012 the FAS of Russian Federation canceled the decision and penalty imposed on us by the FAS subdivision in the Republic of Bashkortostan.

In October 2011, FAS began an investigation of our and Vimpelcom's actions suspecting violation of antimonopoly laws by coordinated pricing of iPhone 4 handsets. In April 2012, the FAS decided that we and Vimpelcom were in violation of antimonopoly laws in respect of iPhone 4 pricing. Further, FAS imposed an administrative fine on us in the amount of RUB 16.8 million which we paid in August 2012.

In October 2013, the FAS subdivision in the Pskov Region began an investigation into our, Vimpelcom's and MegaFon's GPRS pricing in the Pskov Region. In December 2013 the investigation was closed as no violation of the antimonopoly laws was identified.

In November 2013, the FAS subdivision in the Rostov Region charged us and LLC "I-CUBE" with a violation of antimonopoly laws by entering into an agreement allowing preferential terms for the services of LLC "I-CUBE". FAS issued an order to cease the violation and imposed a fine of RUB 0.1 million on MTS. We do not intend to appeal this decision of the FAS subdivision in the Rostov Region.

In January 2014, the FAS subdivision in the Khanty-Mansiysk Autonomous District-Yugra charged Comstar-regions with violation of antimonopoly legislation by abusing its dominant position on the Internet access market by setting different prices in different municipalities of the region. FAS also issued an order to cease the violations. On January 17, 2014, the arbitrazh court of Khanty-Mansiysk Autonomous District-Yugra cancelled the decisions and the order of the FAS subdivision in the Khanty-Mansiysk Autonomous District-Yugra.

In January 2014, the FAS subdivision in the Rostov Region charged MTS with violation of antimonopoly laws by setting a monopoly tariff on cable TV tariffs services in the Rostov-on-Don city. The investigation is currently in progress.

On April 29, 2013, the Board of Directors approved a dividend policy, whereby we will aim to make dividend payments to our shareholders for 2013, 2014 and 2015 in the amount of at least 75% of MTS OJSC's free cash flow, but not less than RUB 40 billion. For the purposes of our dividend calculation we utilize a simplified form of free cash flow — which we define as Operating Cash Flow less capital expenditures. In case of fluctuations in the amount of dividends payable from the set up goals, MTS OJSC should provide the reasons of that fluctuations.

Annual dividend payments, if any, must be recommended by our Board of Directors and approved by the Annual General Meeting of Shareholders (AGM). We anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of ADSs, net of the depositary's fees and expenses. Accordingly, the value of dividends received by holders of ADSs will be subject to fluctuations in the exchange rate between the ruble and the dollar.

At a meeting held on April 11, 2014, the Board of Directors recommended that an AGM approves annual dividends of RUB 18.6 per ordinary MTS share (RUB 37.2 per ADS), or a total of approximately RUB 38 billion, based on the full-year 2013 financial results. Upon acceptance by the AGM and completion of this payment, we will have paid out up to RUB 49 billion based on our fiscal year 2013 financial results.

The Board of Directors set the date for our AGM for June 24, 2014. The record date for the Company's shareholders and ADS holders entitled to participate in the AGM has been set for May 6, 2014. The Board of Directors recommended that the AGM sets the record date for shareholders and ADS holders entitled to receive dividends for the 2013 fiscal year for July 7, 2014.

Subsequent to year end, key aspects of the Ukrainian economy continued to deteriorate. Opposing groups have organized protests in Kiev and other regions of the country. A referendum on the status of Crimea was held on March 16, 2014 followed by Crimea acceding to the Russian Federation on March 21, 2014. These protests and the related unrest have caused a deterioration of Ukraine's credit ratings and depreciation of the national currency. The political tension in Ukraine remains high and in case of further escalation, conflict or imposition of any sanctions applicable to our operations could result in a negative impact on our business in Ukraine including on its financial position and results of operations, and such impact, if any, could be significant.

Raising financing from Citibank Europe and Swedish Export Credit Corporation

On March 12, 2014, we entered in a credit facility agreement with Citibank Europe PLC and Swedish Export Credit Corporation for up to $300 million (RUB 10,920 million at the date of transaction). The credit facility will be used for the development of our mobile networks through purchases of equipment from Ericsson. The facility will be made available in one tranche with maturity in July 2024. The interest rate is LIBOR + 0.9%. The amounts may be drawn by us over the next 12 months and will be linked to equipment purchases for the development of LTE networks.

On April 11, 2014 we signed an agreement with Sberbank to open a non-revolving credit line for a total amount of RUB 20 billion. The credit line matures in July 2015 and bears an annual interest rate of 9.96%. The line will be used to support general corporate needs.

In March 2014, we received requests for the provision of information from the United States Securities and Exchange Commission and the United States Department of Justice relating to an investigation of the Group's former subsidiary in Uzbekistan. See also Note 4 to our audited consolidated financial statements. As the aforementioned US government investigations are at an early stage, we cannot predict the outcome of the investigations, including any fines or penalties that may be imposed, and such fines or penalties could be significant.

During the period from December 31, 2013 to April 17, 2014, the Russian Ruble further depreciated by 10% and 11% against the U.S. dollar and the Euro, respectively. Since a portion of our capital expenditures, borrowings and certain operating costs are denominated in U.S. dollars and Euros, this and any further devaluation could adversely affect our results of operations in 2014. We would

experience an estimated currency exchange loss of RUB 4.3 billion on our U.S. dollar- and Euro-denominated net monetary liabilities as a result of a hypothetical 10% and 11% depreciation of the Russian Ruble against the U.S. dollar and Euro at December 31, 2013, respectively. This sensitivity analysis includes only outstanding U.S. dollar- and Euro- denominated monetary items.

In March 2014, we repurchased part of MTS International Notes due 2020 with nominal value of USD 50.2 million (RUB 1,819 million at the date of transaction).

In April 2014, we sold a 49% stake in Business-Nedvizhimost to Sistema for cash consideration of RUB 3.1 billion to be paid by June 30, 2014. Before the disposal an ownership interest in Business-Nedvizhimost was held by MGTS-Nedvizhimost CJSC, a subsidiary of MGTS, and was accounted for using the equity method. See Note 3 to our audited consolidated financial statements.

Our ADS, each representing two ordinary shares, have been listed on the NYSE since July 6, 2000 under the symbol "MBT." Our ordinary shares have been listed on MICEX (currently Moscow Exchnage) since December 2003. In addition, we issued additional ordinary shares in connection with our merger with Comstar, which have been listed on MICEX (currently Moscow Exchange) since May 2011. The shares of the additional issuance became fully fungible with our previously issued ordinary shares in July 2011. Set forth below, for the periods indicated, are the high and low closing prices per

ADS as reported by the NYSE and the high and low closing prices per ordinary share as reported by the Moscow Exchange.

Our common stock has been listed on the Moscow Interbank Currency Exchange (currently Moscow Exchange) since December 2003. ADSs, each representing two shares of our common stock, have been listed on the New York Stock Exchange under the symbol "MBT" since July 6, 2000. Our U.S. dollar-denominated notes due in 2020 are listed on the Irish Stock Exchange. Our ruble-denominated notes are listed on the Moscow Exchange.

We describe below material provisions of our charter and certain requirements of Russian legislation. In addition to this description, we urge you to review our charter to learn its complete terms.

Article 2.1 of our charter provides that our principal purpose is to obtain profits through the planning, marketing, establishing and operating communications network and facilities, to provide access to Internet and to render communications services on our license territories.

We are registered with the Ministry of Taxes and Duties of the Russian Federation under the state registration number 1027700149124.

Pursuant to our charter, we have the right to issue registered common stock, preferred stock and other securities provided for by legal acts of the Russian Federation with respect to securities. Our capital stock currently consists of 2,066,413,562 common shares, each with a nominal value of 0.10 rubles, all of which are issued and fully paid. Under Russian legislation, charter capital refers to the aggregate nominal value of the issued and outstanding shares. We are also authorized to issue an additional 100,000,000 common shares with a nominal value of 0.10 rubles each. No preferred shares are authorized or outstanding. Preferred stock may only be issued if corresponding amendments have been made to our charter pursuant to a resolution of the general meeting of shareholders. We have issued only common stock. The Joint Stock Companies Law requires us to dispose of any of our shares that we acquire within one year of their acquisition or, failing that, reduce our charter capital. We refer to such shares as treasury shares for the purposes hereof. Russian legislation does not allow for the voting of such treasury shares. Any of our shares that are owned by our subsidiaries are not considered treasury shares under Russian law (i.e., they are considered outstanding shares), and our subsidiaries holding such shares are able to vote and dispose of such shares without any further corporate actions by our shareholders or board of directors. As of April 1, 2014, we had no treasury shares. 90,881 of treasury shares which we repurchased in March 2013 during the process of merger of our subsidiaries into MTS pursuant to the requirements of applicable law were sold in March 2014 in order to comply with the relevant legal requirements. Together with our wholly owned subsidiaries we held a total of 77,491,498 shares, of which approximately 87.8% were held in form of ADSs. See "Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders." In our consolidated financial statements prepared in accordance with U.S. GAAP, these shares are considered treasury shares (i.e., they are considered not outstanding).

As of the date of this document, we had more than ten thousand shareholders for purposes of the Joint Stock Companies Law.

Holders of our common stock have the right to vote at all shareholders' meetings. As required by the Joint Stock Companies Law and our charter, all shares of our common stock have the same nominal value and grant identical rights to their holders. Each fully paid share of common stock, except for treasury shares, gives its holder the right to:

The Joint Stock Companies Law and our charter provide existing shareholders with a pre-emptive right to purchase shares or securities convertible into shares during an open subscription in the amount proportionate to their existing shareholdings. In addition, the Joint Stock Companies Law provides shareholders with a pre-emptive right to purchase shares or securities convertible into shares, in an amount proportionate to their existing shareholdings, during a closed subscription if the shareholders voted against or did not participate in the voting on the decision approving such subscription. The pre-emptive right does not apply to a closed subscription to the existing shareholders provided that

such shareholders may each acquire a whole number of shares or securities convertible into shares being placed in an amount proportionate to their existing shareholdings. We must provide shareholders with written notice of their pre-emptive right to purchase shares and the period during which shareholders can exercise their pre-emptive rights. Such period may not be less than 20 or, under certain circumstances, 45 days. We cannot sell the shares or securities convertible into shares which are subject to the pre-emptive rights during this period.

The Joint Stock Companies Law and our charter set forth the procedure for determining the quarterly and annual dividends that we may distribute to our shareholders. We may declare dividends based on our first quarter, six month, nine month or annual results. Dividends are recommended to a shareholders' meeting by a majority vote of the board of directors and approved by the shareholders by a majority vote. A decision on quarterly, six month and nine month dividends must be taken within three months of the end of the respective quarter at the extraordinary shareholders' meeting; and a decision on annual dividends must be taken at the annual general shareholders' meeting. The dividend approved at the shareholders' meeting may not be more than the amount recommended by the board of directors.

The Joint Stock Companies Law allows dividends to be declared only out of net profits calculated under RAS as long as the following conditions have been met:

The Joint Stock Companies Law and the Securities Market Law have been amended on December 29, 2012 to adopt new dividend payment rules that came into force January 1, 2014. These amendments include new rules on determining the shareholders entitled to dividend distribution whereby the list of such shareholders is fixed at date determined in the decision of the General shareholders' meeting on the distribution of dividends. The date shall be not earlier than 10 days and not later than 20 days following the date of such decision. The dividends are to be paid within 25 days from such date to private shareholders registered in the share register of the company and within 10 days to nominal holders and professional managers. If shares are held on a depo account with a depository, dividends will be transferred to such shareholders by such depositary within 7 days of receipt of funds by the depositary.

Under Russian legislation, liquidation of a company results in its termination without the transfer of rights and obligations to other persons as legal successors. The Joint Stock Companies Law and our charter allow us to be liquidated:

Following a decision to liquidate us, the right to manage our affairs would pass to a liquidation commission appointed by a shareholders' meeting. In the event of an involuntary liquidation, the court may assign the duty to liquidate the company to its shareholders. Creditors may file claims within a period to be determined by the liquidation commission, but such period must not be less than two months from the date of publication of notice of liquidation by the liquidation commission.

The Civil Code of the Russian Federation gives creditors the following order of priority during liquidation:

Claims of creditors in obligations secured by a pledge of the company's property ("secured claims") are satisfied out of the proceeds of sale of the pledged property prior to claims of any other creditors except for the creditors of the first and second priorities described above, provided that claims of such creditors arose before the pledge agreements in respect of the company's property were made. To the extent that the proceeds of sale of the pledged property are not sufficient to satisfy secured claims, the latter are satisfied simultaneously with claims of the fourth priority creditors as described above.

The Federal Law on Insolvency (Bankruptcy), however, provides for a different order of priority for creditors' claims in the event of bankruptcy.

The remaining assets of a company are distributed among shareholders in the following order of priority:

The Civil Code of the Russian Federation and the Joint Stock Companies Law generally provide that shareholders in a Russian joint stock company are not liable for the obligations of a joint stock company and bear only the risk of loss of their investments. This may not be the case, however, when one company is capable of determining decisions made by another company. The company capable of determining such decisions is called an "effective parent." The company whose decisions are capable of being so determined is called an "effective subsidiary." The effective parent bears joint and several responsibility for transactions concluded by the effective subsidiary in carrying out these decisions if:

Thus, a shareholder of an effective parent is not itself liable for the debts of the effective parent's effective subsidiary, unless that shareholder is itself an effective parent of the effective parent. Accordingly, a shareholder will not be personally liable for our debts or those of our effective subsidiaries unless such shareholder controls our business and the conditions set forth above are met.

In addition, an effective parent is secondarily liable for an effective subsidiary's debts if an effective subsidiary becomes insolvent or bankrupt resulting from the action or omission of an effective parent only when the effective parent has used the right to give binding instructions, knowing that the consequence of carrying out this action would be insolvency of this effective subsidiary. This is the case no matter how the effective parent's capability to determine decisions of the effective subsidiary arises, such as through ownership of voting securities or by contract. In these instances, other shareholders of the effective subsidiary may claim compensation for the effective subsidiary's losses from the effective parent that caused the effective subsidiary to take any action or fail to take any action knowing that such action or failure to take action would result in losses.

A decision on any issuance of shares or securities convertible into shares by closed subscription, or an issuance by open subscription of common shares or securities convertible into common shares constituting 25% or more of the number of issued common shares, requires a three-quarters majority vote of a shareholders' meeting. Otherwise, a decision to increase the charter capital by increasing the nominal value of issued shares requires a majority vote of a shareholders' meeting. In certain circumstances provided in our charter, a decision to increase the charter capital may be taken by our board of directors. In addition, the issuance of shares above the number provided in our charter necessitates a charter amendment, which requires a three-quarters affirmative vote of a shareholders' meeting.

The Joint Stock Companies Law requires that the value of newly issued shares be determined by the board of directors based on their market value but not less than their nominal value. The price of newly issued shares for existing shareholders exercising their pre-emptive right to purchase shares could be less than the price paid by third parties, but not less than 90% of the price paid by third parties. Fees paid to intermediaries may not exceed 10% of the shares placement price. The board of directors shall value any in-kind contributions for new shares, based on the appraisal report of an independent appraiser.

Russian securities regulations set out detailed procedures for the issuance and registration of shares of a joint stock company. These procedures require:

The Joint Stock Companies Law does not allow a company to reduce its charter capital below the minimum charter capital required by law, which is 100,000 rubles for an open joint stock company. The Joint Stock Companies Law and our charter require that any decision to reduce our charter capital through the repurchase and cancellation of shares, be made by a majority vote of a shareholders' meeting and through reduction of the nominal value of shares, by a three-quarter majority vote of a shareholders' meeting. Additionally, within 3 business days of a decision to reduce our charter capital,

we must notify the federal executive body in charge of the state registration of legal entities on the decision taken and publish within the same 3-day period a notice regarding the charter capital reduction, as well as a second notice one month after the first notice is published. Our creditors, whose claims arose before the decision on the charter capital decrease was taken, would then have the right to demand in court, within 30 days of the second publication of the notice, early termination or settlement of relevant obligations by us, as well as compensation for damages.

The Joint Stock Companies Law and our charter allow our shareholders or the board of directors to authorize the repurchase of up to 10% of our shares in exchange for cash. The repurchased shares pursuant to a board decision must be resold at the market price within one year of their repurchase or, failing that, the shareholders must decide to cancel such shares and decrease the charter capital. Repurchased shares do not bear voting rights.

Shares repurchased pursuant to a decision of our shareholders' meeting to decrease the overall number of shares are cancelled at their redemption.

The Joint Stock Companies Law allows us to repurchase our shares only if, at the time of repurchase:

Our subsidiaries are not restricted from purchasing our shares, and our subsidiaries can vote these shares.

The Joint Stock Companies Law and our charter provide that our shareholders may demand repurchase of all or some of their shares as long as the shareholder demanding repurchase voted against or did not participate in the voting on the decision approving any of the following actions:

We may spend up to 10% of our net assets calculated under RAS on the date of the adoption of the decision which gives rise to a share redemption demanded by the shareholders. If the value of shares in respect of which shareholders have exercised their right to demand repurchase exceeds 10% of our net assets, we will repurchase shares from each such shareholder on a pro-rata basis. Repurchase of the shares is at a price agreed on by the board of directors, but shall not be less than the market price.

Russian legislation requires that a joint stock company maintains a register of its shareholders. Ownership of our registered shares is evidenced solely by entries made in such register. Any of our shareholders may obtain an extract from our register certifying the number of shares that such

shareholder holds. Since May 10, 2000, Registrar NIKoil OJSC has maintained our register of shareholders.

The purchase, sale or other transfer of shares is accomplished through the registration of the transfer in the shareholder register, or the registration of the transfer with a depositary if shares are held by a depositary. The registrar or depositary may not require any documents in addition to those required by Russian legislation in order to transfer shares in the register. Refusal to register the shares in the name of the transferee or, upon request of the beneficial holder, in the name of a nominee holder, is not allowed, except in certain instances provided for by Russian legislation, and may be challenged in court.

Russian legislation requires that each joint stock company establish a reserve fund to be used only to cover the company's losses, redeem the company's bonds and repurchase the company's shares in cases when other funds are not available. Our charter provides for a reserve fund of 15% of our charter capital, funded through mandatory annual transfers of at least 5% of our net profits until the reserve fund has reached the 15% requirement.

Russian securities regulations require us to make the following periodic public disclosures and filings:

The powers of a shareholders' meeting are set forth in the Joint Stock Companies Law and in our charter. A shareholders' meeting may not decide on issues that are not included in the list of its competence by the Joint Stock Companies Law. Among the issues which the shareholders have the power to decide are:

Voting at a shareholders' meeting is generally based on the principle of one vote per share of common stock, with the exception of the election of the board of directors, which is done through cumulative voting. Decisions are generally passed by a majority vote of the voting shares present at a shareholders' meeting. However, Russian law requires a three-quarters majority vote of the voting shares present at a shareholders' meeting to approve the following:

The quorum requirement for our shareholders' meetings is met if holders of shares (or their representatives) accounting for more than 50% of the issued voting shares are present. If the 50% quorum requirement is not met, another shareholders' meeting with the same agenda may (and, in case of an annual shareholders' meeting must) be scheduled and the quorum requirement is satisfied if holders of shares (or their representatives) accounting for at least 30% of the issued voting shares are present at that meeting.

The annual shareholders' meeting must be convened by the board of directors between March 1 and June 30 of each year, and the agenda must include the following items:

A shareholder or group of shareholders owning in the aggregate at least 2% of the issued voting shares may introduce proposals for the agenda of the annual shareholders' meeting and may nominate candidates for the board of directors, counting commission and review commission. Any agenda proposals or nominations must be provided to the company no later than 100 calendar days after the preceding financial year end.

Extraordinary shareholders' meetings may be called by the board of directors on its own initiative, or at the request of the review commission, the independent auditor or a shareholder or group of shareholders owning in the aggregate at least 10% of the issued voting shares as of the date of the request. The decision by the board of directors to call or reject the call for an extraordinary shareholders' meeting shall be sent to the party that requested the meeting within three days after such a decision was made.

A general meeting of shareholders may be held in a form of a meeting or by absentee ballot. The form of a meeting contemplates the adoption of resolutions by the general meeting of shareholders through the attendance of the shareholders or their authorized representatives for the purpose of discussing and voting on issues of the agenda, provided that if a ballot is mailed to shareholders for participation at a meeting convened in such form, the shareholders may complete and mail the ballot back to the company without personally attending the meeting. A general meeting of the shareholders by absentee ballot contemplates the determination of collecting shareholders' opinions on issues of the agenda by means of a written poll.

The following issues cannot be decided by a shareholders' meeting by absentee ballot:

All shareholders entitled to participate in a general shareholders' meeting must be notified of the meeting, whether the meeting is to be held in the form of a meeting or by absentee ballot, no less than 30 days prior to the date of the meeting, and such notification shall specify the agenda for the meeting. However, if it is an extraordinary shareholders' meeting to elect the board of directors, shareholders must be notified at least 70 days prior to the date of the meeting. Only those items that were set out in the agenda to shareholders may be voted upon at a general shareholders' meeting.

If a nominal holder of the shares registers in the register of shareholders, then a notification of the shareholders' meeting shall be sent to the nominal holder. The nominal holder must notify its clients in accordance with Russian legislation or an agreement with the client.

The list of shareholders entitled to participate in a general shareholders' meeting is to be compiled on the basis of data in our shareholders register on the date established by the board of directors, which date may neither be earlier than the 10 days after the date of adoption of the board resolution to hold a general shareholders' meeting nor more than 50 days before the date of the meeting (or, in the case of an extraordinary shareholders' meeting to elect the board of directors, not later than 80 days before the date of the meeting).

The right to participate in a general meeting of shareholders may be exercised by a shareholder as follows:

Our charter provides that our entire board of directors is up for election at each annual general shareholders' meeting. Our board of directors is elected through cumulative voting. Under cumulative voting, each shareholder may cast an aggregate number of votes equal to the number of shares held by such shareholder multiplied by the number of persons to be elected to our board of directors, and the shareholder may give all such votes to one candidate or spread them between two or more candidates. Before the expiration of their term, the directors may be removed as a group at any time without cause by a majority vote of a shareholders' meeting.

The Joint Stock Companies Law requires at least a five-member board of directors for all joint stock companies, at least a seven-member board of directors for a joint stock company with more than 1,000 holders of voting shares, and at least a nine-member board of directors for a joint stock company with more than 10,000 holders of voting shares. Only natural persons (as opposed to legal entities) are entitled to sit on the board. Members of the board of directors are not required to be shareholders of the company. The actual number of directors is determined by the company's charter or a decision of the shareholders' meeting. Our charter provides that our board of directors consists of at least seven members, which number may be increased pursuant to a decision of the general meeting of shareholders. Currently, our board of directors consists of nine members.

The Joint Stock Companies Law prohibits a board of directors from acting on issues that fall within the competence of the general shareholders' meeting. Our board of directors has the power to perform the general management of the company, and to decide, among others, the following issues:

Our charter generally requires a majority vote of the directors present for an action to pass, with the exception of actions for which Russian legislation requires a unanimous vote or a majority vote of the disinterested and independent directors, as described therein. A board meeting is considered duly assembled and legally competent to act when a majority of elected directors is present.

Our internal regulation "On the Board of Directors of OJSC Mobile TeleSystems" (the "Regulation") was approved by the annual shareholders' meeting on June 25, 2013. In accordance with clause 2.2.2 of the Regulation, the members of the board of directors have the right to:

In accordance with clause 2.3.2 of the Regulation, the members of the board of directors must:

Under the Joint Stock Companies Law, certain transactions defined as "interested party transactions" require approval by disinterested directors or shareholders of the company. "Interested party transactions" include transactions involving a member of the board of directors or member of any executive body of the company (including the company's chief executive office and/or the company's managing organization), any person that owns, together with any affiliates, at least 20% of a company's issued voting shares or any person who is able to direct the actions of the company, if that person and/or that person's spouse, parents, children, adoptive parents or children, brothers or sisters and/or their affiliates, is/are:

The Joint Stock Companies Law requires that an interested party transaction by a company with more than 1,000 shareholders (holders of voting shares) be approved by a majority vote of the independent directors of the company who are not interested in the transaction. For purposes of this rule, an "independent director" is a person who is not, and within the year preceding the decision to approve the transaction was not, a general director/president, a member of any executive body or an affiliate of the company, or a member of the board of directors or any management body of the company's management organization. Additionally, such person's spouse, parents, children, adoptive parents or children, brothers or sisters may not, and within the year preceding the date of the decision to approve the transaction did not, occupy positions in the executive bodies of the company or positions on the board of directors or of any management body of the company's management organization. For companies with 1,000 or fewer shareholders, an interested party transaction must be adopted by a majority vote of the directors who are not interested in the transaction if the number of these directors is sufficient to constitute a quorum.

Approval by a majority of shareholders who are not interested in the transaction is required if:

Approval by a majority of shareholders who are not interested in the transaction may not be required, until the next annual shareholders' meeting, for an interested party transaction if such transaction is substantially similar to transactions concluded by the company and the interested party in the ordinary course of business before such party became an interested party with respect to the transaction.

The approval of interested party transactions is not required in the following instances:

The Joint Stock Companies Law defines a "major transaction" as a transaction, or a number of interrelated transactions, involving the acquisition or disposal, or a possibility of disposal (whether directly or indirectly) of property having a value of 25% or more of the balance sheet value of the assets of a company determined under RAS, with the exception of transactions conducted in the ordinary course of business or transactions involving the placement of common stock, or securities convertible into common stock. Major transactions involving assets having a value ranging from 25% to 50% of the balance sheet value of the assets of a company determined under RAS require unanimous approval by all members of the board of directors or, failing to receive such approval, a simple majority vote of a shareholders' meeting. Major transactions involving assets having a value in excess of 50% of the balance sheet value of the assets of a company determined under RAS require a three-quarters majority vote of a shareholders' meeting.

The above rules may be supplemented through CBR rulemaking, which may result in a wider, narrower or more specific interpretation of these rules by the government and judicial authorities, as well as by market participants.

Pursuant to the Federal Law on Competition, FAS must approve in advance acquisitions of voting capital stock of a joint stock company involving (1) companies with a combined value of assets or combined annual revenues under RAS exceeding a certain threshold, or (2) companies registered as having more than a 35% share of a certain commodity market or otherwise occupying a dominant position on the market, and which would result in a shareholder (or a group of affiliated shareholders) holding more than 25%, 50% or 75% of the voting capital stock of such company, or in a transfer between such companies of assets or rights to assets, the value of which exceeds a certain amount. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate, the government may regulate our subscriber tariffs and restrict our operations."

Pursuant to the Strategic Foreign Investment Law, investments resulting in a foreign entity or a group of entities receiving control over a company with strategic importance for the national defense and security of the Russian Federation (a "Strategic Company") require prior approval from the state authorities. The procedure for issuing such consent involves a special governmental commission on control of foreign investments ("Governmental Commission"), which was established by the Resolution of the Government of Russia dated July 6, 2008 as the body responsible for granting such consents, and FAS, which is authorized to process applications for consent from foreign investors. "Control" means an ability to determine, directly or indirectly, decisions taken by a Strategic Company, whether through voting at the general shareholders' (participants') meeting of the Strategic Company, participating in the board of directors or management bodies of the Strategic Company, or acting as the external management organization of the Strategic Company, or otherwise. As a result, "control" will generally be deemed to exist if an entity or a group of entities acquires more than 50% of the shares (or participation interest in share capital) of a Strategic Company, or if through contract or securities with voting rights it is able to appoint more than 50% of the members of the board of directors or of the management board of a Strategic Company.

Furthermore, if a foreign entity or group of entities holding securities of a Strategic Company or other entity that exercises control over this company becomes a direct or indirect holder of voting shares in an amount that is considered to give it direct or indirect control over this company in accordance with the Strategic Foreign Investment Law due to a change in allocation of voting shares pursuant to the procedures provided by Russian law (e.g., as a result of a buy-back of its shares by the relevant company), then such entity or group of entities will have to apply for state approval of its control within three months after it received such control.

In addition, foreign investors are required to notify this authorized governmental agency about any transactions undertaken by them resulting in the acquisition of 5% or more of the charter capital of strategically important companies.

On April 8, 2009, MTS OJSC and two of our subsidiaries, Dagtelecom LLC (Dagtelecom LLC has since been merged into MTS) and Sibintertelecom CJSC, were added to the register of companies occupying a dominant position on the market with a market share exceeding 25% for the purpose of the Strategic Foreign Investment Law.

See also "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The Strategic Foreign Investment Law imposes certain restrictions on us and our existing and potential foreign shareholders, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

Under Russian law, a person acquiring, directly or indirectly, 5% or more of our common shares is required to notify us and the CBR of, and we must then publicly disclose, such acquisition, as well as any subsequent acquisitions or disposals resulting in the crossing of 5%, 10%, 15%, 20%, 25%, 30%, 50%, 75% or 95% thresholds of our outstanding common shares by such person.

A holder of more than 5% of our common shares is required to file with us and the CBR information about its controlling shareholder (if any) or notify us and the CBR about the absence of any such controlling shareholders.

Our subsidiaries are required to notify us and the CBR about the acquisition of our common shares. We are required to publicly disclose the acquisition of our common shares by our subsidiaries.

Foreign persons registered as individual entrepreneurs in Russia who acquire shares in a Russian joint stock company and foreign companies that acquire shares in a Russian joint stock company may need to notify the Russian tax authorities within one month following such acquisition. However, the procedure for notifying the Russian tax authorities by foreign companies that are not registered with such tax authorities at the time of their share acquisition remains unclear.

The following is a description of contracts that we and/or our subsidiaries are a party to and that are or may be material to our business.

On May 28, 2013, we issued U.S. dollar-denominated Loan Participation Notes in the amount of $500 million (RUB 16.4 billion as of December 31, 2013) with an annual interest rate of 5.00% and a maturity in June 2023. The proceeds will be used for general corporate purposes. The notes were issued by MTS International Funding Limited, a private company organized and existing as a private limited company under the laws of Ireland, and are listed on the Irish Stock Exchange. Proceeds were on-lent to us pursuant to a loan agreement between us and MTS International Funding Limited.

The loan agreements relating to our notes due 2023 sets forth various occurrences, each of which would constitute an event of default. If an event of default, other than an event of default arising from events of bankruptcy, insolvency or bankruptcy- related reorganization, occurs and is continuing, either the lender, the trustee or the holders of at least 25% in principal amount of the outstanding notes may accelerate the maturity of all of the notes. If an event of default arising from events of our bankruptcy,

insolvency or bankruptcy-related reorganization occurs and is continuing, then the principal of, and accrued interest on, all of the notes will automatically become immediately due and payable without any declaration or other act on the part of the lender, holders of notes or the trustee.

Covenants in the loan agreement relating to our notes due 2023 limit our ability to create liens on our properties, merge or consolidate with another person or convey our properties and assets to another person. In addition, if we experience certain types of mergers, consolidations or other changes in control, noteholders will have the right to require us to redeem the notes at 101% of their principal amount, plus accrued interest. We are also required to take all commercially reasonable steps necessary to maintain a rating of the notes from Moody's or Standard & Poor's. If we fail to meet these covenants, after certain notice and cure periods, the noteholders can accelerate the debt to be immediately due and payable.

On April 3, 2013, we issued exchange-traded ruble bond on Moscow Exchange. The bond is worth RUB 10 billion and has a maturity of ten years. Coupons are to be paid semiannually at the rate of 8.25%. Bond holders will have the right under a five-year put option to sell the bonds to us. The proceeds from the bond replacement will be used for general corporate needs.

In July 2011, we signed a credit facility agreement with ING Bank Evrasia. The facility is a revolving credit line, which allows us to borrow up to RUB 2.5 billion. The funds are to be used for the financing of our working capital and are available till July 2012. The facility can be drawn in RUB, EUR or USD. The interest rate is MosPrime, EURIBOR or LIBOR + 1.25%, depending on the currency of the drawn funds. The repayment period is to be agreed with the bank, but cannot exceed 3 months and extend beyond the final maturity date, which is July 2012. In July 2012 and 2013, we signed two amendments to this credit facility agreement. The interest rate margin was increased from +1.25% to 1.50% and the final maturity date was set at July 14, 2014. The arrangement fee paid under the agreement amounted to RUB 6.2 million. As of December 31, 2013, we have not made use of the facility.

In July 2012, we entered into a credit facility agreement with Rosbank in the total amount of RUB 2,500 million. The funds under the facility are to be used for our general corporate purposes and are available till July 24, 2014. The interest rate is MosPrime_1m/2m/3m + 1.25% depending on the loan period. The loan period cannot exceed three months and cannot extend beyond the final maturity date, which is July 24, 2014. In August 2013, we signed an amendment to this credit facility agreement. The interest rate margin was decreased from +1.25% to 0.75%. We are to pay additional interest of 0.25% p.a. on the drawn amount as a fee for credit account maintenance (however the fee cannot exceed RUB 6.3 million). As of December 31, 2013, we have not made use of the facility.

In May 2012, we signed a framework agreement with Citybank. This framework agreement sets up general terms and conditions for short-term provision of funds for the financing of our working capital. The funds will be provided for the maximum period of 182 days in RUB. The interest rate is MosPrime +1.50%. The amount of funds provided will be set up individually in a special funds' request. Each request is subject to Citybank approval. The fee of 0.25% from the amount of funds granted is payable within 3 days after the funds transfer. Advanced repayment is allowed. The fee on early redemption is defined as the difference between the amount of interest expense for the period

between the date of advanced repayment and maturity date set in the request and the amount of interest the bank could earn if it had placed the funds on deposit for the respective period. As of December 31, 2013, we have not made use of the facility.

In December 2010, we entered into two non-revolving credit line facilities in the amount of RUB 60.0 billion and RUB 40.0 billion, respectively. The credit facility in the amount of RUB 60 billion was utilized for refinancing of the outstanding loans from Sberbank. The credit line for RUB 40 billion was used for financing the roll-out of MTS's 3G networks in 2011. In July 2013, we repaid RUB 20 billion of the RUB 40 billion credit facility. In December 2013 the tenor of the credit agreements was increased from December 2017 until March 2020, while the annual interest rate on both lines was lowered from 8.50% to 8.45%.

The Federal Law on Currency Regulation and Currency Control which came into effect on June 18, 2004 sets forth certain restrictions on settlements between residents of Russia with respect to operations involving foreign securities (including ADSs), including requirements for settlement in Russian rubles.

Russian companies must repatriate 100% of their receivables from the export of goods and services (with a limited number of exceptions concerning, in particular, certain types of secured financing).

Restrictions on the remittance of dividends, interest or other payments to non-residents

The Federal Law on Foreign Investments in the Russian Federation of July 9, 1999 specifically guarantees foreign investors the right to repatriate their earnings from Russian investments. However, the evolving Russian exchange control regime may materially affect your ability to do so.

Currently, ruble dividends on common shares may be converted into U.S. dollars without restriction. However, the ability to convert rubles into U.S. dollars is also subject to the availability of U.S. dollars in Russia's currency markets. Although there is an existing market within Russia for the conversion of rubles into U.S. dollars, including the interbank currency exchange and over-the-counter and currency futures markets, the further development of this market is uncertain.

The following discussion describes the material Russian corporate income tax and personal income tax consequences to you if you are a U.S. holder of ADSs and a resident of the United States for purposes of the United States—Russia income tax treaty and are fully eligible for benefits under the United States—Russia income tax treaty. Subject to certain provisions of the United States—Russia income tax treaty relating to limitations on benefits, a U.S. resident under the treaty is generally defined as a person liable, under the laws of the United States, to U.S. tax (other than taxes with respect to only of income from sources in the United States or capital situated therein) by reason of your domicile, residence, citizenship, place of incorporation, or any other similar criterion (and, for income derived by a partnership, trust or estate, residence is determined in accordance with the residence of the person liable to tax with respect to such income). The treaty provides for a procedure to resolve matters where a resident of the United States qualifies as a Russian tax resident under Russian domestic rules. The treaty also provides for the non-application of treaty benefits to certain types of entities.

Additionally, the benefits under the United States—Russia income tax treaty discussed in this document generally are not available to U.S. persons who hold ADSs in connection with the conduct of a business in the Russian Federation through a permanent establishment as defined in the United States—Russia income tax treaty. Subject to certain exceptions, a U.S. person's permanent establishment under the United States—Russia income tax treaty is a fixed place of business through which such person carries on business activities in the Russian Federation (generally including, but not limited to, a place of management, a branch, an office and a factory). Under certain circumstances, a U.S. person may be deemed to have a permanent establishment in the Russian Federation as a result of activities carried on in the Russian Federation through agents of the U.S. person. This summary does not address the treatment of holders described in this paragraph.

Treaty benefits may be potentially available to U.S. tax residents that are not subject to limitations on treaty benefits under the treaty, do not operate through a permanent establishment in Russia and are foreign legal entities (i.e., a legal entity or organization in each case not organized under Russian law) or individuals not considered Russian tax residents under Russian law. Under current Russian law, the Russian tax residency for individuals is generally determined based on the number of days a person spends in Russia in a 12-month period. While the current version of the law specifies that an individual present in Russia for an aggregate period of 183 days in any consecutive 12-month period will be considered as a tax resident, exactly how to apply the 12-month rule is the subject of debate and is not entirely clear. The Ministry of Finance of the Russian Federation has issued several letters implying that the final tax status of an individual taxpayer shall still be defined for a whole calendar year by counting the days spent in Russia within the relevant calendar year. Accordingly, the approach used, in practice, to determine the tax residence of an individual for a given tax year (calendar year) remains the same as under the previous legislation i.e., to be considered a Russian tax resident, the taxpayer should spend at least 183 days in Russia in a calendar year.

All of the foregoing tax consequences are based on information in effect as of the date of this document and are subject to change, possibly on a retroactive basis, after the date of this document. This discussion is also based, in part, on representations of the depositary, and assumes that each obligation in the deposit agreement and any related agreements will be performed in accordance with its terms. The discussion with respect to Russian legislation is based on our understanding of current Russian law and Russian tax rules, which are subject to frequent change and varying interpretations.

The following discussion is not intended as tax advice to any particular investor. It is also not a complete analysis or listing of all potential Russian corporate income and personal income tax consequences to you of ownership of ADSs. We urge you to consult your own tax adviser regarding the specific Russian tax consequences of the ownership and disposition of ADSs under your own particular factual circumstances.

The Russian tax rules in relation to ADS holders (that would affect U.S. holders) are characterized by significant uncertainties and limited interpretive guidance. Recent amendments to the tax rules have clarified the status of the ADS holders as beneficial owners of the income from the underlying shares by establishing that the custodian holding the depo account with the shares underlying the ADSs acting as the tax agent and determines amounts of the withholding tax based on the information about the ADS holders and their tax residency status as provided by the program depositary. However, the

application of the baseline tax rate for ADS holders and any double tax treaty relief is available only if the tax treaty residence of the holder is provided to the custodian along with the other information prescribed by the Tax code. In relation to ADS holders such information is to be provided by the ADS holders to the depositary, who relays it to the custodian, who acts as the tax agent and withholds the taxes when making transferring the dividends to the depositary. It is currently unclear how the depositary will collect the necessary information from ADS holders. Thus, while a U.S. holder may technically be entitled to benefit from the provisions of the United States—Russia income tax treaty, in practice such relief may be difficult or impossible to obtain.

Russian tax law and procedures are also not well developed, and local tax inspectors have considerable autonomy and often interpret tax rules without regard to the rule of law. Both the substantive provisions of Russian tax law and the interpretation and application of those provisions by the Russian tax authorities may be subject to more rapid and unpredictable change than in jurisdictions with more developed capital markets.

Dividends paid to U.S. holders generally will be subject to Russian withholding tax at a 15% rate. The tax burden may be reduced to 5% or 10% under the United States—Russia income tax treaty for eligible U.S. holders; a 5% rate may potentially apply for U.S. holders who are legal entities owning 10% or more of the company's voting shares, and a 10% rate applies to dividends paid to eligible U.S. holders in other cases, including dividend payments to individuals and legal entities owning less than 10% of the company's voting shares. However, according to the recent amendments to the Tax Code, U.S. holders will only be able to utilize the 5% reduced rate through tax reimbursement procedures, as the tax agent is required to use the baseline tax rate established by the code or the applicable tax treaty, whichever is appropriate. See also "—United States—Russia Income Tax Treaty Procedures."

Recent amendments to the Tax Code have also introduced a new 30% withholding tax rate to be applied to the dividends paid out in relation to shares underlying an ADS program where the information regarding the holders of the ADSs including the overall number of securities held in a specific tax jurisdiction is not provided by the depositary to the custodian holding the depo account with the underlying shares and acting as the tax agent.

From a practical perspective, it may not be possible for the depositary to collect the necessary information from all ADS holders and submit the relevant information to the custodian.

Therefore, with respect to legal entities or organizations who are U.S. holders, the custodian may be obligated to withhold income tax at a rate of 30% from dividend payments made to the trustee, unless the information on the ADS holder, the respective amount of ADS held and its tax residency is provided to the depositary and thereafter to the custodian within 7 days of the date on which the shareholders entitled to dividend payout are determined according the the relevant decision of the general shareholders meeting. The same amendments have also introduced an expedited refund process whereby the information regarding the ADSs not provided to the custodian can be submitted within 25 days of the date of the payment of the dividends to the depositary in order for the custodian to refund the difference between the increased 30% tax rate used and the tax rate the respective ADS holders are entitled to according to their tax residency, however this process is new and not tested and it is unclear how it will work in practice. Although non-resident holders of ADSs may apply for a refund of a portion of the tax withheld under an applicable tax treaty, the procedure to do so may be time consuming and no assurance can be given that the Russian tax authorities will grant a refund. See "—United States—Russia Income Tax Treaty Procedures."

With respect to individuals who are U.S. holders of ADSs and who are Russian tax non-residents, the custodian may also be obligated to withhold income tax at the rate of 30% from dividend payments made to the depositary. Where withholding of personal income tax is not performed, individuals who

are U.S. holders of ADSs will then be required to submit an annual personal tax return to the Russian tax authorities and pay Russian income tax at a rate of 15% as under Russian law an individual should report on his or her tax liabilities in case the relevant tax was due but not withheld by a tax agent from the relevant payment. When submitting the tax return, individuals who are U.S. holders may claim an application of the reduced rates of withholding tax established by the relevant treaty, provided that the procedures described in "—United States—Russia Income Tax Treaty Procedures" are complied with. Obtaining the respective approvals from the tax authorities may be time-consuming and burdensome.

If the appropriate information is not provided to the depositary for transfer to the custodian in a timely manner, the custodian may have to withhold tax at the 30% rate, and U.S. holders that are legal entities qualifying for a reduced rate under the United States—Russia income tax treaty then may file claims for a refund within three years with the Russian tax authorities.

For individuals claiming treaty relief, the documents substantiating the right for treaty benefits should be submitted to the Russian tax authorities within one year after the end of the year to which these benefits relate. In practice, where withholding is performed, the tax authorities may refuse to refund or credit the 15% tax withheld from payment of dividends to the depositary and, therefore, it is possible that individuals who are U.S. holders may be subject to up to a 30% effective tax rate (general tax rate for Russian tax non-residents) on their share of dividends.

Generally, capital gains arising from the sale, exchange or other disposition of securities by legal entities or organizations that are non-resident holders should not be subject to tax in Russia if immovable property located in Russia constitutes 50% or less of our assets. If more than 50% of our assets were to consist of immovable property located in Russia, legal entities or organizations that are non-resident holders of the securities should be subject to a 20% withholding tax on the gross proceeds from the sale, exchange or other disposition of securities, the difference between the sales, exchange or other disposition price and the acquisition costs of the ADSs, determined in accordance with Russian tax deductibility rules. The corporate income tax decreased from 24% to 20% starting from January 1, 2009.

However, an exemption applies if immovable property located in Russia constitutes more than 50% of our assets and the securities are traded on a foreign stock exchange. In that case, the proceeds from the sale of securities on that foreign stock exchange shall not be deemed to be income from sources in Russia, and accordingly, will not be subject to taxation in Russia. The determination of whether more than 50% of our assets consist of immovable property located in Russia is inherently factual and is made on an on-going basis and the relevant Russian legislation and regulations in this respect are not entirely clear. Hence, there can be no assurance that immovable property owned by us and located in Russia does not currently and will not constitute more than 50% of our assets as at the date of the sale of ADSs by non-residents.

Where the ADSs are sold by legal entities or organizations to persons other than a Russian company or a foreign company or an organization with a registered permanent establishment in Russia, even if the resulting capital gain is considered taxable in Russia, there is currently no mechanism under which the purchaser will be able to withhold the tax and remit it to the Russian budget.

Under the United States—Russia income tax treaty, capital gains from the sale of shares and/or ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the treaty) were to consist of immovable property located in Russia.

The taxation of the income of tax non-resident individuals depends on whether this income is received from Russian or non-Russian sources. Russian tax law considers the place of sale as an indicator of source. Accordingly, the sale of securities outside of Russia by individuals who are non-resident holders should not be considered Russian source income and, therefore, should not be taxable in Russia. However, Russian tax law gives no clear indication as to how the place of sale of securities should be defined in this respect. Therefore, the Russian tax authorities may have a certain amount of flexibility in concluding whether a transaction is in Russia or out of Russia.

The sale, exchange or other disposal of the shares and ADSs by non-resident individual holders in Russia will be considered Russian source income and will be subject to tax at a rate of 30% on the difference between the sales price and the acquisition costs of such securities, as well as other documented expenses, such as depositary expenses and broker fees, among others, defined by the tax rules.

Under Russian law, the acquisition costs and related expenses can be deducted at the source of payment if the sale was made by a non-resident holder through a licensed Russian broker, trust manager or other person that carries out operations under agency or commission agreements, or other agreements in favor of a taxpayer. Such party (as defined above) should also act as a tax agent and withhold the applicable tax. Such tax agent will be required to report to the Russian tax authorities the amount of income realized by the non-resident individual and tax withheld upon the sale of the securities.

Otherwise, if the sale is made to individuals but not through a tax agent, generally no withholding needs to be made and the non-resident holder will have an obligation to file a tax return, report his income realized and apply for a deduction of acquisition expenses (which includes filing of support documentation). Although Russian tax law imposes tax agent responsibility only on professional trustees, brokers or dealers, in practice, the tax authorities may require Russian legal entities and organizations or foreign companies with any registered presence in Russia that are not professional trustees, dealers or brokers to act as tax agents and withhold the applicable tax when purchasing securities from non-resident individuals.

Under the United States—Russia income tax treaty, capital gains from the sale of the ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the United States—Russia Tax Treaty) were to consist of immovable property located in Russia. If this 50% threshold is not met, individuals who are U.S. holders may seek to obtain the benefit of the United States—Russia income tax treaty in relation to capital gains resulting from the sale, exchange or other disposition of the ADSs.

In order to apply the provisions of relevant double tax treaties, the individual holders should receive clearance from the Russian tax authorities as described below. See "—United States—Russia Income Tax Treaty Procedures" below.

The Russian Tax Code does not contain a requirement that a non-resident holder that is a legal entity or organization must obtain tax treaty clearance from the Russian tax authorities prior to receiving any income in order to qualify for benefits under an applicable tax treaty. However, a non-resident legal entity or organization seeking to obtain relief from or reduction of Russian withholding tax under a tax treaty must provide to a Russian company or foreign company or organization acting through its Russian registered presence, which is a tax agent (i.e., the entity paying income to a non-resident) a confirmation of its tax treaty residence that complies with the applicable requirements and a Russian translation attached to it in advance of receiving the relevant income. The

tax residency confirmation needs to be renewed on an annual basis and provided to the payer of income before the first payment of income in each calendar year.

A U.S. holder may obtain the appropriate certification by mailing completed forms, together with the holder's name, taxpayer identification number, the tax period for which certification is required, and other applicable information, to the United States Internal Revenue Service. The procedures for obtaining certification are described in greater detail in the instructions to Internal Revenue Service Form 8802. As obtaining the required certification from the Internal Revenue Service may take at least six to eight weeks, U.S. holders should apply for such certification as soon as possible.

In accordance with the Russian Tax Code, to rely on tax treaty benefits, a non-resident holder who is an individual must present to the tax authorities an official document confirming his residency in the home country issued by the competent authorities in his/her country of residence and also other supporting documentation including a statement confirming the income received and the tax paid in the home country, also confirmed by the relevant foreign tax authorities, duly translated and apostilled or pass through a consular legalization. Technically, such a requirement means that an individual cannot rely on the tax treaty until he or she pays the tax in the jurisdiction of his or her residence. Therefore, advance relief from or reduction of withholding taxes for individuals will generally be impossible as it is very unlikely that the supporting documentation for the treaty relief can be provided to the tax authorities and approval from the latter obtained before any payments are made to individuals. A non-resident holder which is an individual may apply for treaty-based benefits within one year following the end of the tax period in which the relevant income was received and the tax was withheld.

If a non-resident holder which is a legal entity or organization does not obtain double tax treaty relief at the time that income or gains are realized and tax is withheld by a Russian tax agent, the non-resident holder may apply for a refund within three years from the end of the tax period (a calendar year) in which the tax was withheld. To process a claim for a refund, the Russian tax authorities require (i) apostilled or legalized confirmation of the tax treaty residence of the non-resident at the time the income was paid, (ii) an application for the refund of the tax withheld in a format provided by the Russian tax authorities and (iii) copies of the relevant contracts under which the foreign entity received income, as well as payment documents confirming the payment of the tax withheld to the Russian budget (Form 1012DT for dividends and interest and Form 1011DT for other income are designed by the Russian tax authorities to combine requirements (i) and (ii) specified above). The Russian tax authorities may require a Russian translation of the above documents if they are prepared in a foreign language. The refund of the tax withheld should be granted within one month of the filing of the above set of documents with the Russian tax authorities. However, procedures for processing such claims have not been clearly established and there is significant uncertainty regarding the availability and timing of such refunds.

Recent amendments to the Tax Code have established additional requirements to the reimbursement procedure referred to above, identifying further documents that need to be provided to the tax authorities. These include: 1) a document confirming the rights of the ADS holder to the ADS as of the date on which the shareholders entitled to the dividend payout are set according to the relevant decision of the General shareholders meeting, 2) a document evidencing the actual amount of income received by the ADS holder, 3) a document with information about the custodian that transferred the dividend amounts to the depositary, and 4) documents confirming the ADS holder's compliance with the requirements of the Tax Code and/or the relevant income tax treaty provisions necessary for application of a reduced rate. The procedures referred to above are new and no assurance can be given that the custodian will be able to apply the respective double tax treaties when paying dividends to non-resident holders or that ADS holders would be successful in receiving relevant tax refunds.

Neither the depositary nor us has or will have any obligation to assist an ADS holder with the completion and filing of any tax forms.

No Russian stamp duty will be payable by the holders of ADSs upon carrying out of transactions with the securities as discussed above (i.e., on a purchase of the securities, sale of the securities, etc.).

The following is a general description of certain material United States federal income tax consequences that apply to you if you are, for United States federal income tax purposes, a beneficial owner of ADSs that is an individual who is a citizen or resident of the United States, a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia, an estate the income of which is subject to U.S. federal income tax regardless of its source, or a trust, if a United States court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person (in each case, a "U.S. Holder"). This discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the Internal Revenue Service ("IRS"), all as publicly available and in effect as of the date of this document. These authorities are subject to differing interpretations and may change, possibly retroactively, resulting in U.S. federal income tax consequences different from those discussed below. No ruling has been or will be sought from the IRS with respect to the matters discussed below, and there can be no assurance that the IRS will not take a contrary position regarding the tax consequences of the acquisition, ownership or disposition of ADSs, or that any such contrary position would not be sustained by a court. If a partnership (including any entity treated as a partnership for United States federal income tax purposes) is an owner of ADSs, the United States federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Accordingly, partnerships that hold ADSs and partners in such partnerships are urged to consult their tax advisors regarding the specific U.S. federal income tax consequences to them. The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:

In addition, this summary is limited to U.S. Holders holding ADSs as "capital assets" within the meaning of Section 1221 of the Code and whose functional currency is the U.S. dollar. The discussion below does not address the effect of the recently effective Medicare tax on "net investment income" or of any United States state or local tax law or foreign tax law. This discussion also does not address any tax consequences relating to the direct ownership of ordinary shares.

The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. For purposes of applying United States federal income tax law, we believe, and the following discussion assumes, that a holder of anADS should be treated as the owner of the underlying shares of common stock represented by that ADS, although this matter is not free from doubt.

The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the shares underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying shares. Accordingly, the analysis of the creditability of Russian withholding taxes described below and the availability of the reduced tax rate for dividends received by certain non-corporate U.S. Holders (discussed below) could be affected by actions taken by intermediaries in the chain of ownership between the holder of ADSs and our company if as a result of such actions the holders of ADSs are not properly treated as beneficial owners of underlying shares and future actions that may be taken by the U.S. Treasury. The remainder of this discussion assumes that a holder of an ADS will be treated as the beneficial owner of the underlying shares of common stock represented by such ADS for United States federal income tax purposes.

Subject to the passive foreign investment company rules described below, for United States federal income tax purposes, the gross amount of a distribution, including any Russian withholding taxes, paid by us with respect to ADSs will be treated as a taxable foreign source dividend on the date of actual or constructive receipt by the depositary to the extent of our current and accumulated earnings and profits, computed in accordance with United States federal income tax principles. If you are a non-corporate U.S. Holder such dividends may be "qualified dividend income" that is taxed at the lower applicable capital gains rate provided that certain conditions are satisfied, including (1) certain holding period requirements are satisfied, (2) either (a) our ADSs continue to be listed on the New York Stock Exchange (or other national securities exchange that is registered under section 6 of the Securities Exchange Act of 1934, as amended, or the Nasdaq Stock Market) or (b) we are eligible for the benefits of the United States—Russia income tax treaty, and (3) we are not, for the taxable year in which the dividend was paid, or in the preceding taxable year, a "passive foreign investment company" with respect to your ADSs (as discussed below). Distributions with respect to ADSs in excess of our current and accumulated earnings and profits will be applied against and will reduce your tax basis in such ADSs and, to the extent in excess of such tax basis, will be treated as gain from a sale or exchange of such ADSs. You should be aware that we do not intend to calculate our earnings and profits for United States federal income tax purposes and, unless we make such calculations, you should assume that any distributions with respect to ADSs generally will be treated as a dividend, even if such distributions would otherwise be treated as a return of capital or as capital gain pursuant to the rules described above. If you are a corporation, you will not be allowed a deduction for dividends received in respect of distributions on ADSs, which is generally available for dividends paid by U.S. corporations. U.S. Holders are strongly urged to consult their tax advisors as to the U.S. federal income tax treatment of any distribution received with respect to ADSs.

The amount of any distribution paid in rubles will equal the U.S. dollar value of such rubles, calculated using the exchange rate in effect on the date of actual or constructive receipt by the depositary, regardless of whether the payment is actually converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange rate fluctuations during the period from the date of receipt by the depositary to the date the rubles are converted into U.S. dollars will be treated as ordinary income or loss from sources within the United States for foreign tax credit limitation purposes. Additionally, you may be required to recognize foreign currency gain or loss on the receipt of a refund of Russian withholding tax pursuant to the United States—Russia income tax treaty to the

extent the United States dollar value of the refund differs from the dollar equivalent of that amount on the date of receipt of the underlying distribution.

Russian withholding tax at the rate applicable to you under the United States—Russia income tax treaty should be treated as a foreign income tax that, subject to generally applicable limitations and conditions, may be eligible for credit against your U.S. federal income tax liability or, at your election, may be deducted in computing taxable income. If Russian tax is withheld at a rate in excess of the rate applicable to you under the United States—Russia income tax treaty, you may not be entitled to credits for the excess amount, even though the procedures for claiming refunds and the practical likelihood that refunds will be made available in a timely fashion are uncertain. If the dividends are qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation will generally be limited to the gross amount of the dividend, multiplied by the reduced rate divided by the highest rate of tax normally applicable to dividends.

The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For United States foreign tax credit purposes, a dividend distribution with respect to the ADSs will be treated as foreign source "passive category income" but could, in the case of certain U.S. Holders, constitute "general category income." The rules relating to the determination of the foreign tax credit, or deduction in lieu of the foreign tax credit, are complex and you should consult your tax advisors with respect to those rules.

Subject to the passive foreign investment company rules described below, the sale or other taxable disposition of ADSs will generally result in the recognition of gain or loss in an amount equal to the difference between the amount realized on the sale or other taxable disposition and your adjusted basis in such ADSs. That gain or loss will be capital gain or loss and will be long-term capital gain or loss if you have held the ADSs for more than one year. If you are a non-corporate U.S. Holder, such recognized long-term capital gain is generally subject to a reduced rate of United States federal income tax. Limitations may apply to your ability to offset capital losses against ordinary income.

Gain or loss recognized on the sale of ADSs will generally be treated as U.S. source income or loss for foreign tax credit purposes. The use of any foreign tax credits relating to any Russian taxes imposed upon such sale may be limited. You are strongly urged to consult your tax advisors as to the availability of tax credits for any Russian taxes withheld on the sale of ADSs.

A non-U.S. corporation generally will be a passive foreign investment company (a "PFIC"), in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable "look-through" rules, either (i) at least 75% of its gross income is "passive income" or (ii) at least 50% of the average value of its assets is attributable to assets which produce passive income or are held for the production of passive income.

We do not believe that we were a PFIC for the year ended December 31, 2012. However, our possible status as a PFIC must be determined annually and may be dependent in part on the market price of our ADSs, which may be volatile. Therefore, our possible status as a PFIC may be subject to change. Thus there can be no assurance that we will not be treated as a PFIC in our current taxable year or in the future. If we were to be treated as a PFIC, U.S. Holders generally would be required to pay additional taxes on certain distributions and gains on sales or other dispositions (including pledges) of the ADSs, at tax rates that may be higher than those otherwise applicable. You should consult your tax advisors regarding the application of the PFIC rules to your investment in the ADSs.

Dividend payments with respect to ADSs and proceeds from the sale or exchange of ADSs may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status generally must provide such certification on IRS Form W-9. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

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

Certain U.S. Holders who are individuals may be required to report information relating to an interest in the ADSs, subject to certain exceptions (including an exception for ADSs held in accounts maintained by certain financial institutions). U.S. Holders should consult their tax advisors regarding the effect, if any, of this requirement on their ownership and disposition of the ADSs.

We are exposed to market risk from changes in interest rates and foreign currency exchange rates. We are subject to market risk deriving from changes in interest rates, which may affect the cost of our financing. Foreign exchange risks exist to the extent our revenues, costs and debt obligations are denominated in currencies other than the functional currency in the countries of our operations.

We are exposed to variability in cash flow risk related to our variable interest rate debt and exposed to fair value risk related to our fixed-rate notes. As of December 31, 2013, RUB 35,595 million, or 16.2% of our total indebtedness, including capital leases, was variable interest rate debt, while RUB 183,552 million, or 83.8% of our total indebtedness, including capital leases, was fixed interest rate debt.

The table below presents principal cash flows and related weighted average interest rates for indebtedness by contractual maturity dates as of December 31, 2013.

We would have experienced an additional interest expense of approximately RUB 174 million on an annual basis as a result of a hypothetical increase in the LIBOR/EURIBOR by 1% over the current rate as of December 31, 2013. In addition, the 8.45% interest rate set for our Sberbank facilities due 2020 totaling RUB 80.0 billion is dependent on the volume of turnovers on the bank accounts of certain our entities. In case the average volume falls below a certain limit, the interest rate will be increased by 1%. Such rate increase would cause our interest expense to increase by approximately RUB 800 million on an annual basis. The fair value of our publicly traded fixed-rate notes as of December 31, 2013, ranged from 93.75% to 118.60% of the notional amount. As of December 31, 2013, the difference between the carrying value and the fair value of other fixed rate debt, including capital lease obligations, was immaterial. For details of our fixed-rate debt, refer to Note 15 of our audited consolidated financial statements. The fair value of variable rate debt approximates its carrying value.

We use derivative financial instruments to reduce our exposure to adverse fluctuations in interest rates. We primarily focus on reducing risk caused by the fluctuations in interest rates for our variable-rate long-term debt. According to our policy, we have entered into various variable-to-fixed interest rate swap agreements. The table below presents a summary of our variable-to-fixed interest rate swap agreements.

As of December 31, 2013, approximately 1.1% of our variable interest rate debt was hedged against interest rate risks. We continue to consider other financial instruments available to us to mitigate exposure to interest rate fluctuations. We do not enter into derivative financial instruments for trading purposes.

We have also entered into several cross-currency interest rate swap agreements. These contracts, which hedge the risk of both interest rate and currency fluctuations, assume periodical exchanges of both principal and interest payments from ruble-denominated amounts to U.S. dollar- and euro-denominated amounts, to be exchanged at specified rates. The rates were determined with reference to the market spot rates upon issuance. These contracts also include an interest rate swap of a fixed U.S. dollar- and euro-denominated interest rate to a fixed ruble-denominated interest rate. All of our cross-currency interest rate swaps agreements mature in 2019 and 2020.

The table below presents a summary of our cross-currency interest rate swap agreements:

Type of derivative	Maturity	Notional amount (at inception)

The following tables show, for the periods indicated, certain information regarding the exchange rate between the ruble and the U.S. dollar, based on data published by the CBR. These rates may differ from the actual rates used in preparation of our financial statements and other financial information provided herein.

The exchange rate between the ruble and the U.S. dollar quoted by the CBR for April 24, 2014 was 35.66 rubles per U.S. dollar.

The following tables show, for the periods indicated, certain information regarding the exchange rate between the hryvnia and the U.S. dollar, based on data published by the National Bank of Ukraine. These rates may differ from the actual rates used in preparation of our financial statements and other financial information provided herein.

The exchange rate between the hryvnia and the U.S. dollar quoted by the National Bank of Ukraine for April 24, 2014 was 11.51 hryvnias per U.S. dollar.

We have exposure to fluctuations in the value of the U.S. dollar relative to the Russian ruble, Ukrainian hryvnia, Turkmen manat and Armenian dram, which are the functional currencies in our countries of operation. As a result, we may face translation losses, increased debt service payments and increased capital expenditures and operating costs should these currencies depreciate against the U.S. dollar.

In 2009, we entered into two foreign currency option agreements to manage our exposure to changes in currency exchange rates related to our U.S. dollar- denominated debt obligations. Under the agreements, we have put and call option rights to acquire $80.0 million of U.S. dollars (RUB 2,538 million) at rates within a range specified in the contracts. The first option agreement to acquire $40.0 million (RUB 1,269 million) expired in 2010 and was not exercised, whereas the second option agreement to acquire $40.0 million (RUB 1,269 million) expired unexercised in April 2011. In 2010, we additionally entered into foreign currency option agreements to manage our exposure to changes in currency exchange rates related to our U.S. dollar-denominated eurobonds. Under these agreements, we had put and call option rights to acquire $250.0 million (RUB 7,592 million) at rates within a range specified in the contracts. These contracts were not designated for hedge accounting purposes and expired unexercised in January 2012.

A significant part of our capital expenditures, borrowings and certain operating costs (roaming expenses, cost of customer equipment and other costs) are either denominated in U.S. dollars or tightly linked to the U.S. dollar exchange rate, and our U.S. dollar-denominated debt represents our primary future risk of exchange loss in U.S. dollar terms. A decline in the value of the ruble, hryvnia, manat or dram versus the U.S. dollar would result in currency remeasurement losses as the amount of these currencies required to repay U.S. dollar-denominated debt increases. In addition, if any of the ruble, hryvnia, manat or dram declines against the U.S. dollar and tariffs cannot be maintained for competitive or other reasons, our revenues and operating margins could be materially adversely affected and we could have difficulty repaying or refinancing our U.S. dollar-denominated indebtedness and financing our capital expenditures and operating costs.

A portion of our capital expenditures, borrowings and certain operating costs (roaming expenses, costs of customer equipment and other costs) are also denominated in euros. We currently do not hedge against the risk of decline in the ruble, hryvnia, manat or dram against the euro because settlements denominated in euros are not significant.

We would experience a currency exchange loss of RUB 12,124 million on our U.S. dollar-denominated net monetary liabilities as a result of a hypothetical 20.0% increase in the ruble/hryvnia/manat/dram to U.S. dollar exchange rate at December 31, 2013. We would experience a currency exchange gain of RUB 946 million in the fair value of our euro-denominated net monetary liabilities as a result of a hypothetical 20.0% increase in the ruble/hryvnia/manat/dram to euro exchange rate at December 31, 2013. We are unable to estimate future loss of earnings as a result of such changes.

The amounts the Depositary reimbursed or paid are not perforce related to the fees collected by the depositary from ADS holders.

As part of its service to us, the Depositary has agreed to waive fees for the standard costs associated with the administration of our ADS program, associated operating expenses and investor relations advice estimated to total $0.2 million.

Item 14. Material Modifications to the Rights of Security Holders and Use of Proceeds

As of the end of the period covered by this Annual Report on Form 20-F, we carried out an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934).

Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures are effective, as of December 31, 2013, to provide reasonable assurance that the information required to be disclosed in filings and submissions under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions about required disclosure.

There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America.

Internal control over financial reporting refers to a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and effected by our 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:

Management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2013 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control-Integrated Framework (1992).

As a result of management's evaluation of our internal control over financial reporting, management concludes that internal control over financial reporting as of December 31, 2013 was effective.

The effectiveness of our internal control over financial reporting as of December 31, 2013, has been audited and assessed as effective by independent registered public accounting firm ZAO Deloitte & Touche CIS, who has also audited and reported on our consolidated financial statements.

There were no changes in our internal control over financial reporting during the year-ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We have audited the internal control over financial reporting of Mobile TeleSystems OJSC and subsidiaries (the "Group") as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Group'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 Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Group's internal control over financial reporting based on our audit.

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

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's 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. 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2013 of the Group and our report dated March 17, 2014 expressed an unqualified opinion on those financial statements.

Management has evaluated, with the participation of our CEO and CFO, whether any changes in our internal control over financial reporting that occurred during the period covered by this annual report have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on the evaluation we conducted, management has concluded that no such changes have occurred.

Our Board of Directors has determined that Thomas Holtrop is an "audit committee financial expert" as defined in Item 16A of Form 20-F. Mr. Holtrop is "independent" as defined in Rule 10A-3 under the Exchange Act and current New York Stock Exchange listing rules applicable to us. For a description of Mr. Holtrop's experience, please see "Item 6. Directors, Senior Management and Employees—A. Directors and Senior Management—Key Biographies."

We are a company organized under the laws of the Russian Federation and qualify as a foreign private issuer as such term is defined in Rule 3b-4 of the Exchange Act. In accordance with the NYSE corporate governance rules, listed companies that are foreign private issuers are permitted in some circumstances to follow home country practice in lieu of the provisions of the corporate governance rules contained in Section 303A of the NYSE Listed Company Manual that are applicable to U.S. companies. In addition, foreign private issuers listed on the NYSE must disclose any significant ways in which their corporate governance practices differ from those followed by U.S. companies listed on the NYSE. With regard to our corporate governance practices, these differences can be summarized as follows:

We do not currently have a nominating/corporate governance committee. We have a corporate conduct and ethics committee comprising of directors and members of management that is responsible for developing and implementing standards for corporate governance and ethics and making recommendations to the Board of Directors on developing our strategy in the area of corporate

governance and ethics. This committee is also responsible for conducting annual performance evaluations of the Board of Directors.

We have a remuneration and nomination committee comprising of three independent directors. This committee functions pursuant to bylaws approved by the Board of Directors specifying the committee's purpose, duties and responsibilities. The committee is primarily responsible for recommending appointments to key managerial posts, developing a set of requirements and criteria for directors and management executives and developing a remuneration structure and compensation levels for the Board of Directors, the audit committee and management executives (including the CEO).

In accordance with the corporate governance rules of the NYSE applicable to foreign private issuers, we also disclose these differences between our corporate governance practices and those required by the NYSE of listed U.S. companies on our Internet website at www.mtsgsm.com.

We have audited the accompanying consolidated statements of financial position of Mobile TeleSystems OJSC and subsidiaries (the "Group") as of December 31, 2013 and 2012, and the related consolidated statements of operations and comprehensive income, changes in shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2013. These consolidated financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on the consolidated 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 present fairly, in all material respects, the financial position of Mobile TeleSystems OJSC and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Group's internal control over financial reporting as of December 31, 2013 based on the criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 17, 2014 expressed an unqualified opinion on the Group's internal control over financial reporting.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

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

(Amounts in millions of Russian Rubles, unless otherwise stated)

Business of the Group—Open Joint-Stock Company Mobile TeleSystems ("MTS OJSC", or "the Company") was incorporated on March 1, 2000, through the merger of MTS CJSC and Rosico TC CJSC, its wholly-owned subsidiary. MTS CJSC started its operations in the Moscow license area in 1994 and then began expanding through Russia and the CIS. MTS OJSC's majority shareholder is Joint-Stock Financial Corporation Sistema or "Sistema".

In these notes, "MTS" or the "Group" refers to Mobile TeleSystems OJSC and its subsidiaries.

The Group provides a wide range of telecommunications services including voice and data transmission, internet access, pay TV, various value added services through wireless and fixed lines, as well as selling equipment and accessories. The Group's principal operations are located in Russia, Ukraine, Turkmenistan and Armenia. During 2004-2012 the Group also operated in Uzbekistan.

MTS completed its initial public offering in 2000 and listed its shares of common stock, represented by American Depositary Shares, or ADSs, on the New York Stock Exchange under the symbol "MBT". Since 2003 common shares of MTS OJSC have been traded on the Open Joint-Stock Company "Moscow Exchange MICEX-RTS" ("Moscow Exchange").

Since 2009, the Group has been developing its own retail network, operated by Russian Telephone Company CJSC ("RTC"), a wholly owned subsidiary of MTS OJSC.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS

Accounting principles—The Group's entities maintain accounting books and records in local currencies of their domicile in accordance with the requirements of respective accounting and tax legislation. The accompanying consolidated financial statements have been prepared in order to present MTS' financial position and its results of operations and cash flows in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and are expressed in terms of Russian Rubles.

The accompanying consolidated financial statements differ from the financial statements used for statutory purposes in that they reflect certain adjustments, not recorded on the entities' books, which are appropriate to present the financial position, results of operations and cash flows in accordance with U.S. GAAP. The principal adjustments are related to revenue recognition, foreign currency translation, deferred taxation, consolidation, acquisition accounting, depreciation and valuation of property, plant and equipment, intangible assets and investments.

Basis of consolidation—The consolidated financial statements include the accounts of the Company, as well as entities where the Company has operating and financial control, most often through the direct or indirect ownership of a majority voting interest. Those ventures where the Group exercises significant influence but does not have operating and financial control are accounted for using the equity method. Investments in which the Group does not have the ability to exercise significant influence over operating and financial policies are accounted for under the cost method and included in long-term investments in the consolidated statements of financial position. The consolidated financial statements also include accounts of variable interest entities ("VIEs") in which the Group is deemed to

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

be the primary beneficiary. An entity is generally a VIE if it meets any of the following criteria: (i) the entity has insufficient equity to finance its activities without additional subordinated financial support from other parties, (ii) the equity investors cannot make significant decisions about the entity's operations or (iii) the voting rights of some investors are not proportional to their obligations to absorb the expected losses of the entity or receive the expected returns of the entity and substantially all of the entity's activities involve or are conducted on behalf of the investor with disproportionately few voting rights. All significant intercompany transactions, balances and unrealized gains and losses on transactions have been eliminated.

As of December 31, 2013 and 2012, the Company had investments in the following significant legal entities:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

The Group consolidates MTS International, a private company organized and existing as a private limited company under the laws of Ireland, which qualified as a variable interest entity under Financial Accounting Standards Board Accounting Standards Codification ("ASC") 810, Consolidation. The Group is the primary beneficiary of MTS International. MTS International was established for the purpose of raising capital through the issuance of debt securities on the Irish Stock Exchange followed by transferring the proceeds through a loan facility to the Group. In 2010 and 2013, MTS International issued $750 million 8.625% notes due in 2020 and $500 million 5.0% notes due in 2023, respectively (Note 15). The notes are guaranteed by MTS OJSC in the event of default. While the Group does not hold any equity in MTS International, it has concluded that it is the primary beneficiary by virtue of the fact that it has the power to direct the activities of MTS International that most significantly impact its performance and by virtue of the guarantee that exists which means the Group has the obligation to absorb losses of MTS International that could potentially be significant to MTS International.

The table below summarizes the assets and liabilities of MTS International as of December 31, 2013 and 2012:

The MTS International Notes due 2020 and 2023 and related interest payable are fully covered by intercompany receivables from MTS OJSC. MTS International does not perform any other activities except those required for notes servicing. The Group bears all costs incurred by MTS International in connection with the notes' maintenance activities. Such costs for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 2,535 million, RUB 2,011 million and RUB 1,950 million,

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

respectively, and were included in interest expense reported by the Group in the consolidated statements of operations and comprehensive income.

Functional currency translation methodology—As of December 31, 2013, the functional currencies of Group entities were as follows:

In 2013, the Group changed its reporting currency from the U.S. Dollar ("USD") to the Russian Ruble. The Group believes that reporting in Russian Rubles allows for greater transparency with respect to reporting the Group's financial and operating performance as such reporting more closely reflects the profile of the Group's revenues and operating income, a major portion of which are generated in Russian Rubles. In accordance with authoritative guidance, comparative information was restated in Russian Rubles. Remeasurement of the financial statements into functional currencies, where applicable, and translation of financial statements into Russian Rubles has been performed as follows:

For entities whose records are not maintained in their functional currencies, monetary assets and liabilities have been remeasured at the period-end exchange rates. Non-monetary assets and liabilities have been remeasured at historical rates. Revenues, expenses and cash flows have been remeasured at average rates. Remeasurement differences resulting from the use of these rates have been accounted for as currency exchange and translation gains and losses in the accompanying consolidated statements of operations and comprehensive income.

For entities whose records are maintained in their functional currency, which is other than the reporting currency, all year-end assets and liabilities have been translated into U.S. Dollars at the period-end exchange rate set by local central banks. Subsequently U.S. Dollars balances have been translated into Russian Rubles at the period-end exchange rate set by the Central Bank of Russia. Revenues and expenses have been translated at the average exchange rate for the period using cross-currency exchange rate via U.S. Dollar as described above. Translation differences resulting from the use of these rates are reported as a component of other comprehensive income.

Management 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 and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

Significant estimates include the allowance for doubtful accounts and inventory obsolescence, valuation allowance for deferred tax assets for which it is more likely than not the assets will not be realized, the valuation of assets acquired and liabilities assumed in business combinations and income tax benefits, the recoverability of investments and the valuation of goodwill, intangible assets, other long-lived assets, redeemable noncontrolling interest, certain accrued liabilities and financial instruments.

Cash and cash equivalents—Cash and cash equivalents represent cash on hand and in bank accounts and short-term investments, including term deposits, having original maturities of less than three months. The cost of these investments approximates fair value.

Short-term investments and loans—Short-term investments mainly represent investments in a mutual investment fund and time deposits which have original maturities in excess of three months and are repayable in less than twelve months. The investment in the mutual investment fund was classified as an available-for-sale financial asset in the consolidated statements of financial position with unrealized gains of RUB 154 million recorded in other comprehensive income. Deposits are recorded at cost, which approximates fair value (Note 6).

Other investments and loans—Long-term financial instruments consist primarily of investments and loans. Since quoted market prices are not readily available for all of the long-term financial instruments held by the Group, estimates of fair value are computed incorporating various unobservable market inputs. The Group reviews these investments for indicators of impairment on a regular basis. The investments in companies over which the Group has no significant influence are carried at cost. The Group does not evaluate cost-method investments for impairment unless there is an indicator of impairment.

Property, plant and equipment—Property, plant and equipment, including improvements, are stated at cost. Property, plant and equipment with a useful life of more than one year is capitalized at historical cost and depreciated on a straight-line basis over its expected useful life. Construction in progress and equipment held for installation is not depreciated until the constructed or installed asset is ready for its intended use. Maintenance and repair costs are expensed as incurred, while upgrades and improvements are capitalized.

Other intangible assets—Other intangible assets primarily consist of billing, telecommunication, accounting and office software as well as numbering capacity and customer base. These assets are assets with finite useful lives. They are recognized at cost and amortized on a straight-line basis over their estimated useful lives.

Accounts receivable—Accounts receivable are stated net of allowance for doubtful accounts.

Allowance for doubtful accounts—The Group provides an allowance for doubtful accounts based on management's periodic review with respect to the recoverability of trade receivables, advances given, loans and other receivables. Such allowance reflects specific cases, collection trends or estimates based on evidence of collectability. For changes in the allowance for doubtful accounts receivable see Note 7.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

Inventory and spare parts—Inventory is stated at the lower of cost or market value. Inventory cost is determined using the weighted average cost method. Handsets and accessories held for sale are expensed when sold. The Group regularly assesses its inventories for obsolete and slow-moving stock.

Value-added tax ("VAT")—Value-added tax related to sales is payable to the tax authorities on an accrual basis based upon invoices issued to the customer. VAT incurred for purchases may be reclaimed from the state, subject to certain restrictions, against VAT related to sales.

Income taxes—Income taxes of the Group's Russia-incorporated entities have been computed in accordance with Russian legislation. The corporate income tax rate in Russia is 20%. The income tax rate on dividends paid within Russia is 9%. The foreign subsidiaries of the Group are paying income taxes in their respective jurisdictions. Deferred tax assets and liabilities are recognized for differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the tax bases of assets and liabilities that will result in future taxable or deductible amounts. The deferred tax assets and liabilities are measured using the enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. 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 determination, the Group considers all available information, including future reversals of existing taxable temporary differences, projected taxable income, tax strategies and recent financial results.

Uncertain tax positions are recognized in the consolidated financial statements for positions which are considered more likely than not of being sustained based on the technical merits of the position on audit by the tax authorities. The measurement of the tax benefit recognized in the consolidated financial statements is based upon the largest amount of tax benefit that, in management's judgment, is greater than 50% likely of being realized based on a cumulative probability assessment of the possible outcomes.

The Group recognizes interest and penalties related to unrecognized tax benefits and penalties within income taxes.

Asset retirement obligations—The Group calculates asset retirement obligations and an associated asset retirement cost when the Group has a legal or constructive obligation in connection with the retirement of tangible long-lived assets. The Group's obligations relate primarily to the cost of removing its equipment from sites. The Group recorded the present value of asset retirement obligations as other long-term liabilities in the consolidated statements of financial position.

License costs—License costs are being amortized during the initial license period without consideration of possible future renewals, subject to periodic review for impairment, on a straight-line basis over the period of validity, which varies from three to fifteen years.

Goodwill—For acquisitions before January 1, 2009 goodwill represents the excess of the consideration paid over the fair market value of the net identifiable assets acquired in business combinations and is not amortized. For acquisitions after January 1, 2009 goodwill is determined as the

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

excess of the consideration transferred plus the fair value of any noncontrolling interest in the acquiree at the acquisition date over the fair values of the identifiable net assets acquired. Goodwill is reviewed for impairment at least annually or whenever it is determined that one or more impairment indicators exist. The Group determines whether impairment has occurred by assigning goodwill to the reporting unit identified in accordance with the authoritative guidance on intangible assets, and comparing the carrying amount of the reporting unit to its fair value. If an impairment of goodwill has occurred, the Group recognizes a loss for the difference between the carrying amount and the implied fair value of goodwill. During the year ended December 31, 2012 the Group recognized goodwill impairment in amount of RUB 3,523 million related to Uzdunrobita litigation (Note 4) which is included in net income / (loss) from discontinued operations.

Impairment of long-lived assets—The Group periodically evaluates the recoverability of the carrying amount of its long-lived assets. Whenever events or changes in circumstances indicate that the carrying amounts of those assets may not be recoverable, the Group compares undiscounted net cash flows estimated to be generated by those assets to their carrying amount. When the undiscounted cash flows are less than the carrying amounts of the assets, the Group records impairment losses to write the assets down to fair value, measured by estimating the discounted net future cash flows expected to be generated from the use of the assets. None of the Group's long-lived assets were impaired in 2013. An impairment loss in the amount of RUB 16,514 million for the year ended December 31, 2012 was recognized by the Group subsidiaries in Uzbekistan as a result of the events described in Note 4 and included in net income / (loss) from discontinued operations.

Subscriber prepayments—The Group requires the majority of its customers to pay in advance for telecommunications services. All amounts received in advance of services provided are recorded as a subscriber prepayment liability and are not recognized as revenues until the related services have been provided to the subscriber.

Treasury stock—Shares of common stock repurchased by the Group are recorded at cost as treasury stock and reduce the shareholders' equity in the Group's consolidated financial statements.

Revenue recognition—Revenue includes all revenues from the ordinary business activities of the Group. Revenues are recorded net of value-added tax and recognized in the accounting period in which they are earned in accordance with the realization principle.

Revenues derived from wireless, local telephone, long distance, data and video services are recognized when services are provided. This is based upon either usage (minutes of traffic processed, volume of data transmitted) or period of time (monthly subscription fees).

Content revenue is presented net of related costs when the Group acts as an agent of the content providers while gross revenue and related costs are recorded when the Group acts as a primary obligor in the arrangement.

Upfront fees received for connection of new subscribers, installation and activation of wireless, wireline and data transmission services ("connection fees") are deferred and recognized over the estimated average subscriber life, as follows:

The Group calculates an average life of mobile subscribers for each region in which it operates and amortizes connection fees based on the average life specific to that region.

Regulated services—Regulated services provided by the Group primarily consist of local telephone services and services rendered to other operators, such as traffic charges, connection fees and line rental services. Changes in the rate structure for such services are subject to the Federal Tariff Service approval.

Revenue from regulated tariff services represented approximately 5.7%, 6.5% and 6.5% of the consolidated revenue for the years ended December 31, 2013, 2012 and 2011, respectively. This does not include revenue attributable to discontinued operations (Note 4).

Customer incentives—Incentives provided to customers are usually offered on signing a new contract or as part of a promotional offering. Incentives, representing the reduction of the selling price of the service (free minutes and discounts) are recorded in the period to which they relate, when the respective revenue is recognized, as a reduction to both trade receivables and service revenue.

The Group regularly provides special incentives to its retail customers. Generally the Group sells mobile devices of worldwide known brands with an offer of free telecommunication services for a time period from one to twelve months. Such arrangements with a customer provide for two deliverables—a mobile device delivered immediately and mobile services to be consumed in the future. Both deliverables in the arrangement qualify as separate units of accounting. The consideration received from a customer is allocated between the deliverables based on their standalone value on the market, which is deemed to be a vendor-specific objective evidence of selling price. Revenue on the devices sales is recognized at the moment of their sale, and the revenue on provision of free telecommunication services is deferred and recognized in line with their consumption by a subscriber. Revenue generated from multiple-element arrangements in the amount of RUB 3,276 million was recognized in the consolidated statements of operations and comprehensive income for the year ended December 31, 2013. The amounts recognized for the years ended December 31, 2012 and 2011 were not significant. The Group's multiple-element arrangements stipulate no performance-, cancellation-, termination- and refund-type provisions.

Prepaid cards—The Group sells prepaid cards to subscribers separately from the handset. Prepaid cards, used as a method of cash collection, are accounted for as customer advances. These cards allow subscribers to make a predetermined allotment of wireless phone calls and / or take advantage of other

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

services offered by the Group, such as short messages and value-added services. Revenue from the sale of prepaid cards is deferred until the service is rendered to the customer, whereby the customer uses the airtime or the card expires.

Roaming discounts—The Group enters into roaming discount agreements with a number of wireless operators. According to the terms of the agreements the Group is obliged to provide and entitled to receive a discount that is generally dependent on the volume of inter operator roaming traffic. The Group accounts for discounts received from and granted to roaming partners in accordance with the authoritative guidance on customer payments and incentives. The Group uses various estimates and assumptions, based on historical data and adjusted for known changes, to determine the amount of discount to be received or granted. Such estimates are adjusted monthly to reflect newly-available information.

The Group accounts for discounts received as a reduction of roaming expenses and rebates granted as reduction of roaming revenue. The Group considers terms of the various roaming discount agreements in order to determine the appropriate presentation of the amounts receivable from and payable to its roaming partners in its consolidated statements of financial position.

Sales and marketing expenses—Sales and marketing expenses consist primarily of dealers' commissions and advertising costs. Dealers' commissions are linked to revenues received during the six-month period from the date a new subscriber is activated by a dealer. The Group expenses these costs as incurred. Advertising costs for the years ended December 31, 2013, 2012 and 2011, were RUB 8,463 million, RUB 7,908 million and RUB 8,817 million, respectively.

Retirement benefit and social security costs—The Group contributes to the local state pension and social funds on behalf of all its employees.

In Russia all social contributions paid during the year ended December 31, 2013 are represented by payments to governmental social funds, including the Pension Fund of the Russian Federation, the Social Security Fund of the Russian Federation and the Medical Insurance Fund of the Russian Federation. The contributions are expensed as incurred. The amount of social contributions recognized by the Group in Russia amounted to RUB 7,535 million, RUB 6,512 million and RUB 5,877 million in 2013, 2012 and 2011, respectively.

MGTS, a subsidiary of the Group, has historically offered its employees certain benefits upon and after retirement. The cost of such benefits includes interest costs, current service costs, amortization of prior service costs and net actuarial loss / gain. The expense is recognized during an employee's years of active service with MGTS. The recognition of expense for retirement pension plans is impacted by estimates made by management such as discount rates used to value certain liabilities, expected return on assets, future rates of compensation increase and other related assumptions. The Group accounts for pension plans in accordance with the requirements of the Financial Accounting Standards Board ("FASB") authoritative guidance on retirement benefits.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

In Ukraine, Turkmenistan and Armenia the subsidiaries of the Group are required to contribute a specified percentage of each employee's payroll up to a fixed limit to the local pension, unemployment and social security funds. Payments to the pension fund in Ukraine amounted to RUB 2,803 million, RUB 2,493 million and RUB 2,250 million for the years ended December 31, 2013, 2012 and 2011, respectively. Amounts contributed to the pension funds in Turkmenistan and Armenia were not significant.

Redeemable noncontrolling interest—From time to time, to optimize the structure of business acquisitions and to defer payment of the purchase price, the Group enters into put and call option agreements to acquire the remaining noncontrolling stakes in newly acquired subsidiaries. As these put and call option agreements are not freestanding, the underlying shares of such put and call options are classified as redeemable securities and are accounted for at redemption value which is the fair value of redeemable noncontrolling interests as of the reporting date. The fair value of redeemable noncontrolling interests is measured using discounted future cash flows techniques, subject to applicable caps. The noncontrolling interest is measured at fair value using a discounted cash flow technique utilizing significant unobservable inputs ("Level 3" significant unobservable inputs of the hierarchy established by the U.S. GAAP guidance). Changes in the redemption value of redeemable noncontrolling interests are accounted for in the Group's retained earnings. Redeemable noncontrolling interests are presented as temporary equity in the consolidated statements of financial position.

Financial instruments and hedging activities—The Group uses derivative instruments, including interest rate and foreign currency swaps, to manage foreign currency and interest rate risk exposures. The Group measures derivatives at fair value and recognizes them as either other current or other non-current assets or liabilities in the consolidated statements of financial position. Cash flows from derivatives are classified according to their nature. The Group reviews its fair value hierarchy classifications on a quarterly basis. Changes in significant observable valuation inputs identified during these reviews may trigger reclassification of fair value hierarchy levels of financial assets and liabilities. During the years ended December 31, 2013, 2012 and 2011, no reclassifications occurred. The fair value measurement of the Group's derivative instruments is based on the observable yield curves for similar instruments ("Level 2" of the hierarchy established by the U.S. GAAP guidance).

The Group designates derivatives as either fair value hedges or cash flow hedges in case the required criteria are met. Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the consolidated statements of operations and comprehensive income together with any changes in the fair value of the hedged asset or liability that is attributed to the hedged risk.

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recognized in accumulated other comprehensive income. Gains and losses associated with the related hedged items are recognized in the consolidated statements of operations and comprehensive income, depending on their nature.

The gain or loss relating to the ineffective portion is recognized immediately in earnings in the consolidated statements of operations and comprehensive income.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

For derivatives that do not meet the conditions for hedge accounting, gains and losses from changes in the fair value are included in the consolidated statements of operations and comprehensive income (Note 18).

Assets and liabilities related to multiple derivative contracts with one counterparty are not offset by the Group.

The Group does not use financial instruments for trading or speculative purposes.

Fair value of financial instruments—The fair market value of financial instruments, consisting of cash and cash equivalents, short-term investments, receivables and payables, which are included in current assets and liabilities, approximates the carrying value of these items due to the short-term nature of these amounts. The fair value of issued notes as of December 31, 2013 is disclosed in Note 15 and is based on quoted prices in active markets ("Level 1" of the hierarchy established by the U.S. GAAP guidance).

Based on current market interest rates available to the Group for long-term borrowings with similar terms and maturities, the Group believes that the fair value of other fixed rate debt including capital lease obligations and the fair value of variable rate debt approximated its carrying value as of December 31, 2013.

Fair value of financial and non-financial assets and liabilities is defined as 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. The three-tier hierarchy for inputs used in measuring fair value, which prioritizes the inputs used in the methodologies of measuring fair value for assets and liabilities, is as follows:

Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurements. The Group's assessment of the significance of a particular input to the fair value measurements requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

Stock-based compensation—The Group accounts for stock-based compensation under the authoritative guidance on share-based compensation. Under the provisions of this guidance, companies must calculate and record the cost of equity instruments, such as stock options awarded to employees for services received, in the statements of operations and comprehensive income. The cost of the equity instruments is to be measured based on the fair value of the instruments on the date they are granted (with certain exceptions) and recognized over the period during which the employees are required to provide services in exchange for equity instruments. Compensation cost related to phantom stock

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

options granted to the Group's employees recognized in the consolidated statements of operations and comprehensive income for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 483.0 million, RUB 1,445.8 million and RUB 470.2 million, respectively.

Concentration of credit risk—Financial instruments that potentially subject the Group to significant concentrations of credit risk consist principally of cash and cash equivalents, investments, trade accounts receivable, financing receivables and derivatives. The Group maintains cash and cash equivalents, investments, derivatives and certain other financial instruments with various financial institutions. These financial institutions are located in many different geographical regions, and the Group's policy is designed to limit exposure to any one institution. As part of its risk management processes, the Group performs periodic evaluations of the relative credit standing of the financial institutions.

Concentrations of credit risk with respect to trade receivables are limited due to a highly diversified customer base, which includes a large number of individuals, private businesses and state-financed institutions.

New and recently adopted accounting pronouncements—In July 2012, the FASB updated the authoritative guidance on testing indefinite-lived intangible assets for impairment. The update permits the entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. The guidance is effective for all entities for annual and interim goodwill impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this guidance did not have a significant impact on the Group's consolidated financial statements.

In March 2013, the FASB issued the authoritative guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or group of assets within a foreign entity or of an investment in a foreign entity. This new guidance requires that the parent releases any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance is effective for fiscal years and interim reporting periods within those fiscal years beginning after December 15, 2013. The amendments described in the update are to be applied prospectively to derecognition events occurring after the effective date; prior periods are not to be adjusted. The adoption of this guidance is not expected to have a material impact on the Group's consolidated financial statements.

Disposal of Business-Nedvizhimost—In December 2013, the Group sold a 51% stake in Business-Nedvizhimost CJSC to Sistema, a majority shareholder of the Group, for a price of RUB 3.2 billion. Business-Nedvizhimost owns and manages 76 real estate sites and 44 real estate facilities throughout Moscow with a total area of roughly 178,000 sq. m. After the loss of control over the subsidiary, the

Group deconsolidated Business-Nedvizhimost and applied for its remaining 49% interest using the equity method of accounting. The disposal was accounted for as a transaction under common control directly in equity.

Acquisitions of controlling interests in regional fixed line operators—In 2012, as part of its program of regional expansion, the Group acquired controlling interests in a number of fixed line operators in certain regions of Russia. The purchase price for these acquisitions was paid in cash. The acquisitions were accounted for using the acquisition method of accounting.

The following table summarizes the purchase price allocation for regional fixed line operators acquired during the year ended December 31, 2012:



Month of acquisition	August		August		October		October
Region of operations	Central region		Volga region		Central region		Central region
Ownership interest acquired	100	%	100	%	100	%	100	%
Current assets	6		9		4		3		22
Property, plant and equipment	49		11		3		21		84
Goodwill	172		62		115		55		404
Customer base	45		29		54		22		150
Current liabilities	(44	)	(15	)	(13	)	(6	)	(78	)
Non-current liabilities	(9	)	(6	)	(11	)	(4	)	(30	)
Fair value of contingent consideration	(28	)	(10	)	(5	)	—		(43	)


Consideration paid	191		80		147		91		509

The Group's consolidated financial statements reflect the allocation of the purchase price based on a fair value assessment of the assets acquired and liabilities assumed.

Customer base intangibles recognized as a result of the acquisitions are being amortized over a period ranging from 7 to 9 years depending on the type of subscribers.

The recognition of goodwill in the amount of RUB 404 million from the acquisitions is due to the economic potential of the markets in which the acquired companies operate and synergies arising from the acquisitions. Goodwill is attributable to the "Russia" segment.

Tascom—In May 2012, the Group acquired a 100% stake in Tascom CJSC ("Tascom"), a market leader in providing telecommunication services to corporate clients in Moscow and the Moscow region, for RUB 1,437 million. The seller has indemnified the Group against all losses which arise in connection with liability for taxation matters relating to the pre-acquisition period. As of the acquisition date the Group recorded a provision for tax liabilities and a related indemnification asset in the

amount of RUB 236 million relating to this warranty. As of December 31, 2013 the amount of indemnification asset and related provision for tax liabilities was reduced to RUB 139 million.

The Group also should pay to the seller any amounts received for the services rendered by Tascom prior to the acquisition date, capped at RUB 400 million—this contingent consideration arrangement was recorded at fair value of RUB 170 million which was determined based on unobservable inputs ("Level 3" of the hierarchy established by the U.S. GAAP guidance). The fair value was measured as the best estimate of all possible outcomes. During 2012-2013, the contingent consideration in the amount of RUB 170 million was completely paid to the seller.

The acquisition was accounted for using the acquisition method of accounting. The summary of the purchase price allocation for the acquisition was as follows:

The excess of the consideration paid over the value of net assets acquired in the amount of RUB 1,098 million was allocated to goodwill which was attributable to the "Russia" segment and is not deductible for income tax purposes. Goodwill is mainly attributable to the expected synergies from increase of market share and reduction of capital expenditures to be made by the Group to construct optical fiber network.

Disposal of Stream—In May 2012, MTS and Sistema signed a shareholders agreement with respect to the management of Stream LLC ("Stream"), which owns and manages Stream.ru. In addition Sistema contributed RUB 496.1 million into Stream's charter capital giving it an ownership of 55% of Stream, thereby reducing MTS's direct ownership in Stream from 100% to 45%. After a loss of control over the subsidiary, the Group deconsolidated Stream and accounted for its interest using the equity method. The disposal was accounted for as transaction under common control directly in equity.

Increase of stake in MGTS—In December 2011, the Group acquired 29% of the ordinary shares of MGTS from Sistema through acquisition of Sistema-Invenchur for RUB 10.56 billion. In addition the Group assumed debt in the amount of RUB 10.41 billion due and payable by the end of 2011. MGTS is Moscow's incumbent fixed line operator that initially joined the Group as a result of Comstar acquisition. Upon completion of the transaction the Group's ownership stake in MGTS increased to

99.01% of ordinary shares and 69.7% of preferred shares, which overall totals 94.1% of MGTS charter capital. The transaction was accounted for directly in equity.

Acquisitions of controlling interests in regional fixed line operators—In 2011, as part of its program of regional expansion, the Group acquired controlling interests in a number of fixed line operators in certain regions of Russia. The purchase price for these acquisitions was paid in cash. The acquisitions were accounted for using the acquisition method of accounting.

The following table summarizes the purchase price allocation for regional fixed line operators acquired during the year ended December 31, 2011:



Month of acquisition	April		April		August		October
Region of operations	Sibir region		Ural region		Central region		Volga region
Ownership interest acquired	100	%	100	%	100	%	100	%
Current assets	25		80		94		237		436
Property, plant and equipment	307		72		109		2,156		2,644
Goodwill	303		411		372		3,509		4,595
Customer base	63		135		381		230		809
Other non-current assets	1		—		47		59		107

Consideration paid	546		431		749		5,093		6,819

The Group's consolidated financial statements reflect the allocation of the purchase price based on a fair value assessment of the assets acquired and liabilities assumed.

Customer base recognized as a result of the acquisitions is amortized over a period ranging from 8 to 14 years depending on the type of subscribers.

The recognition of goodwill in the amount of RUB 4,595 million is due to the economic potential of the markets in which the acquired companies operate and synergies arising from the acquisitions. Goodwill is attributable to the "Russia" segment.

In June 2012, the authorities of the Republic of Uzbekistan commenced repeat audits of previously audited financial and operating activities of MTS' wholly owned subsidiary Uzdunrobita. On July 17, 2012, Uzdunrobita suspended its services in Uzbekistan pursuant to the order of the State Agency for Communications and Information of Uzbekistan (the "SACI") temporarily suspending the operating license of Uzdunrobita for a period of ten business days. This suspension was subsequently extended to three months due to the decision of the Tashkent Economic Court of July 30, 2012.

On August 13, 2012, the Tashkent Economic Court granted the petition of the SACI to terminate all operating licenses of Uzdunrobita permanently. This decision was subsequently upheld by the appeals and cassation instance courts on August 27, 2012 and April 4, 2013, respectively.

During September-October of 2012, RUB 201 million were seized from Uzdunrobita's bank accounts by the Uzbek State and applied to settle a portion of the State's alleged claims.

On September 17, 2012, the Tashkent City Criminal Court issued a ruling in favor of the Uzbek state authorities authorizing the confiscation of all assets of Uzdunrobita based on a criminal court's verdict which the Tashkent City Criminal Court issued against four employees of Uzdunrobita, despite the Uzdunrobita was not itself a party to such proceedings. Prior to this ruling, the Uzbek law enforcement agencies had frozen all of Uzdunrobita's assets, including cash held in local bank accounts.

In order to comply with the Appeal Decision, Uzdunrobita paid two scheduled installments in November and December 2012 totaling RUB 4,584 million. On January 14, 2013, subsequent to the payment of a portion (RUB 242 million) of the third installment due in January 2013 with all cash remaining in Uzdunrobita's bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy with the Tashkent Economic Court due to its inability to meet its further obligations arising out of the Appeal Decision. On January 18, 2013, the Court initiated bankruptcy proceedings and appointed an external temporary supervisor over Uzdunrobita, and scheduled a further bankruptcy hearing which took place on April 22, 2013.

Considering the adverse impact of such circumstances on the Group's ability to conduct operations in Uzbekistan, the Group tested goodwill and other long-lived assets attributable to Uzbekistan for impairment upon first receiving notification of the investigations. As a result, an impairment loss on the long-lived assets presented in the table below was recorded in the consolidated statements of operations and comprehensive income for the year ended December 31, 2012. In 2013 after the loss of control over Uzdunrobita these losses were assigned to discontinued operations:

The Group used a probability-weighted valuation technique to determine the fair value of the long-lived assets as of December 31, 2012, which was determined based on unobservable inputs ("Level 3" of the hierarchy established by U.S. GAAP guidance). In calculating the future cash flows for use in the assessment of the fair value of long-lived assets, the Group used forecasts for the Uzbekistan telecommunication market and Uzdunrobita's position in that market. The forecasts were based on all available internal and external information, including growth projections and industry experts' estimates.

Separate to the impairments recognized, a liability of RUB 12,706 million relating to the claims was recorded with an associated charge to the consolidated statements of operations and comprehensive income for the year ended December 31, 2012 as the minimum of a range of probable

losses according to management's estimations, as required by U.S. GAAP if no estimate within a range is more likely than any other.

The Group believes that the claims of the Uzbek state authorities against Uzdunrobita that resulted in the initiation of its bankruptcy are unfounded. The Group reserves its right to pursue all available legal options in Uzbekistan and internationally to defend itself, protect its investments and fully recover damages or obtain other relief including from any party involved in depriving MTS of its business and assets in Uzbekistan.

MTS has filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes ("ICSID"), which is part of the World Bank Group, in Washington, D.C. The claim was registered on November 15, 2012. The tribunal was formed on August 29, 2013 and first procedural hearings took place in November 2013.

The results of operations of Uzdunrobita are reported as discontinued operations in the accompanying consolidated statements of operations and comprehensive income and consolidated statements of cash flows for all periods presented. Consolidated statement of financial position was not retrospectively adjusted on discontinued operations and includes Uzbekistan as of December 31, 2012. The gain on disposal recognized in the amount of RUB 3,682 million related to the recycling from accumulated other comprehensive income of the cumulative translation adjustment attributable to Uzdunrobita. The results of discontinued operations of Uzdunrobita for the year ended December 31, 2013, 2012 and 2011 were as follows:

The carrying amount of assets and liabilities related to Uzdunrobita as of April 22, 2013 (the date of deconsolidation) and December 31, 2012 was as follows:

Cash and cash equivalents as of December 31, 2013 and 2012 comprised the following:

The following table summarizes the changes in the allowance for doubtful accounts receivable for the years ended December 31, 2013, 2012 and 2011:

Inventory and spare parts as of December 31, 2013 and 2012 comprised the following:

Obsolescence expense for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 660 million, RUB 759 million and RUB 827 million, respectively, and was included in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income. Spare parts for base stations included in inventory are expected to be utilized within the twelve months following the statements of financial position date.

The net book value of property, plant and equipment as of December 31, 2013 and 2012 was as follows:

Depreciation expense during the years ended December 31, 2013, 2012 and 2011 amounted to RUB 58,599 million, RUB 54,766 million and RUB 50,873 million, respectively.

Depreciation of the assets recorded as capital leases amounted to RUB 276.1 million, RUB 287.8 million and RUB 280.4 million, respectively. Interest expense accrued on capital lease obligations for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 181.5 million, RUB 135.2 million and RUB 53.7 million.

In connection with providing telecommunication services, the Group has been issued various GSM operating licenses by the Russian Ministry of Information Technologies and Communications. In addition to the licenses received directly from the Russian Ministry of Information Technologies and Communications, the Group has been granted access to various telecommunication licenses through acquisitions. In foreign subsidiaries, the licenses are granted by the local communication authorities.

As of December 31, 2013 and 2012, the recorded values of the Group's telecommunication licenses were as follows:

Amortization expense for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 544 million, RUB 662 million and 1,142 million, respectively.

The Group's operating licenses do not provide for automatic renewal. As of December 31, 2013, all licenses covering the territories of the Russian Federation were renewed. The cost to renew the licenses was not significant. The weighted-average period until the next renewal of licenses in the Russian Federation is four years.

License for the provision of telecommunication services in Ukraine was renewed in 2013 and is valid until 2026. License for the provision of telecommunication services in Armenia is valid until 2019. The license in Turkmenistan was suspended by the Turkmenistan Ministry of Communications in December 2010 which resulted in the cessation of the Group's operational activity in Turkmenistan. However, in July 2012, the Turkmenistan Ministry of Communications granted to the Group GSM and 3G licenses for a three-year term and the Group recommenced its operations in Turkmenistan. The license for the provision of telecommunication services in Uzbekistan was withdrawn in August 2012 (Note 4).

Based on the cost of amortizable operating licenses existing at December 31, 2013 and current exchange rates, the estimated future amortization expenses for the five years ending December 31, 2018 and thereafter are as follows:

The actual amortization expense reported in future periods could differ from these estimates as a result of new intangible assets acquisitions, changes in useful lives and other relevant factors.

Operating licenses contain a number of requirements and conditions specified by legislation. The requirements generally include targets for service start date, territorial coverage and expiration date. Management believes that the Group is in compliance with all material terms of its licenses.

The change in the net carrying amount of goodwill for the years ended December 31, 2013 and 2012 by reportable segments was as follows:

As a result of the limited availability of local telephone numbering capacity in Moscow and the Moscow region, the Group entered into agreements for the use of telephone numbering capacity with other telecommunications operators in the region. The costs of acquired numbering capacity with a finite contractual life are amortized over a period of two to ten years in accordance with the terms of the contracts to acquire such capacity.

On December 26, 2012, the State Duma passed a law on the portability of a cellphone number by a subscriber when changing service provider. In connection with this law the Group reclassified numbering capacity with indefinite useful lives in amount of RUB 1,298 million to numbering capacity with finite contractual lives and amortizes it over two years.

Amortization expense for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 14,110 million, RUB 12,482 million and RUB 11,917 million, respectively. Based solely on the cost of amortizable intangible assets existing at December 31, 2013 the estimated future amortization expenses for the five years ending December 31, 2018 and thereafter are as follows:

The actual amortization expense to be reported in future periods could differ from these estimates as a result of new intangible assets acquisitions, changes in useful lives and other relevant factors.

Weighted-average amortization period for billing and telecommunication software acquired during the years ended December 31, 2013 and 2012 is four years.

As of December 31, 2013 and 2012, the Group's investments in and advances to associates comprised the following:

Intellect Telecom—In November 2010, MGTS acquired a 43.8% interest in Intellect Telecom from one of the subsidiaries of Sistema for $12.4 million (RUB 378.5 million at the date of transaction). Intellect Telecom is a research and development innovation center in the field of telecommunications. In March 2011, MGTS acquired a further 6.14% interest in Intellect Telecom in exchange for building of a business center in Moscow City with net book value of $0.8 million (RUB 23.9 million at the date of transaction), thus increasing its share in Intellect Telecom to 49.95%.

Stream—After loss of control over the subsidiary in May 2012, the Group deconsolidated Stream and accounted for the investment using the equity method of accounting (Note 3).

Business-Nedvizhimost—In September 2013, MGTS, the Group's subsidiary, spun off Business-Nedvizhimost CJSC from its wholly-owned subsidiary MGTS-Nedvizhimost and, in December 2013, sold a 51% stake in Business-Nedvizhimost to Sistema. After the loss of control over the subsidiary, the Group deconsolidated Business-Nedvizhimost and accounted for the investment using the equity method of accounting.

MTS Bank—In April 2013, the Group acquired a 25.1% stake in Open Joint Stock Company "MTS Bank" ("MTS Bank") through the purchase of MTS Bank's additional share issuance for RUB 5,089 million. As a result of the transaction, the Group's effective ownership in MTS Bank increased to 26.3%, as MTS OJSC previously owned an interest of 1.7% (such original interest decreased to 1.2% due to additional share issuance) in MTS Bank through its subsidiary MGTS. In September 2012, the Group provided a 10-year subordinated loan to MTS Bank in the amount of RUB 2,100 million at 8.8% p.a.

The financial position and results of operations of MTS Bank as of and for the year ended December 31, 2013 (since acquisition) were as follows:

Summarized financial position and results of operations of other equity method investees as of and for the year ended December 31, 2013 were as follows:

Summarized financial position and results of operations of equity method investees as of and for the year ended December 31, 2012 were as follows:

The Group's share in the total earnings or losses of associates was included in other income in the accompanying consolidated statements of operations and comprehensive income. For the years ended December 31, 2013, 2012 and 2011 this share of earnings amounted to income of RUB 2,472 million, RUB 869 million and RUB 1,430 million, respectively.

As of December 31, 2013 and 2012, the Group's other investments comprised the following:

The Group does not discount promissory notes and loans granted to related parties, interest rates on which are different from market rates. Accordingly, fair value of such notes and loans may be different from their carrying value.

In December 2010, the Group granted a $90.0 million (RUB 2,777 million at the date of transaction) loan to Mr. Pierre Fattouche and Mr. Moussa Fattouche, the holders of a 20% noncontrolling stake in K-Telecom, the Group's subsidiary in Armenia. Simultaneously, the Group signed an amendment to the put and call option agreement for the remaining 20% stake. According to the amendment, the call exercise price shall be reduced by deducting any outstanding balance on the loan amount and all accrued and unpaid interest and any other sums due and outstanding under the loan agreement at the time of exercise (Note 26). Interest accrued on the loan to Mr. Pierre Fattouche and Mr. Moussa Fattouche for the years ended December 31, 2013, 2012 and 2011 amounted to RUB 172.7 million, RUB 174.1 million and RUB 120.5 million, respectively, and was included as a component of interest income in the accompanying consolidated statements of operations and comprehensive income. The fair value of the loan approximates its carrying value due to the marketable interest rate.

In August 2013, the Group invested $21.3 million (RUB 703 million at the date of transaction) in Loan Participation Notes issued by EMIS BV (effective issuer—Renaissance Capital). The Notes bear an interest of 6% per annum and are due in 2015. The Notes are classified as held to maturity and carried at amortized cost. The fair value of the notes approximates their carrying value due to the marketable interest rate.

The Group considers credit risk for other investments in loan receivable and notes to be low.

The Group has an unconditional obligation to repurchase certain MTS OJSC Notes at par value if claimed by the noteholders subsequent to the announcement of sequential coupon. The dates of the announcement for each particular note issue are as follows:

The notes therefore can be defined as callable obligations under the FASB authoritative guidance on debt, as the holders have the unilateral right to demand repurchase of the notes at par value upon announcement of new coupons. The FASB authoritative guidance on debt requires callable obligations to be disclosed as maturing in the reporting period, when the demand for repurchase could be submitted disregarding the expectations of the Group about the intentions of the noteholders. The Group discloses the notes as maturing in 2014 (MTS OJSC Notes due 2018), in 2015 (MTS OJSC Notes due 2020) and in 2018 (MTS OJSC Notes due 2023) in the aggregated maturities schedule as these are the reporting periods when the noteholders will have the unilateral right to demand repurchase.

In June 2013, the Group changed the coupon rate for MTS OJSC Notes due 2018 from 8.00% to 7.00%. Following the announcement of new coupon rates the Group repurchased MTS OJSC Notes due 2018 at the request of eligible noteholders in the amount of RUB 1,875 million.

In December 2013, the Group changed the coupon rate for MTS OJSC Notes due 2018 from 7.00% to 7.50%. Following the announcement of new coupon rates the Group repurchased MTS OJSC Notes due 2018 at the request of eligible noteholders in the amount of RUB 3,891 million.

The fair values of notes based on the market quotes as of December 31, 2013 at the stock exchanges where they are traded were as follows:

Deferred connection fees for the years ended December 31, 2013 and 2012, were as follows:

The Group defers initial connection fees paid by subscribers for the activation of network service as well as one time activation fees received for connection to various value added services. These fees are recognized as revenue over the estimated average subscriber life (Note 2).

In 2009, 2008 and 2007, the Group entered into variable-to-fixed interest rate swap agreements to manage the exposure of changes in variable interest rate related to its debt obligations. The instruments qualify for cash flow hedge accounting under U.S. GAAP requirements. Each interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective hedges. Interest rate swap contracts outstanding as of December 31, 2013 mature in 2014-2015.

In aggregate the Group entered into interest rate swap agreements designated to manage the exposure of changes in variable interest rate relate to 1.1% of the Group's USD- and Euro- denominated bank loans outstanding as of December 31, 2013.

In addition to the above, the Group has also entered into several cross-currency interest rate swap agreements. These contracts hedged the risk of both interest rate and currency fluctuations and assumed periodic exchanges of both principal and interest payments from RUB-denominated amounts to USD- and Euro- denominated amounts to be exchanged at a specified rate. The rate was determined by the market spot rate upon issuance. Cross-currency interest rate swap contracts mature in 2019-2020.

The Group entered into cross-currency interest rate swap agreements designated to manage the exposure of changes in variable interest rate and currency exchange rate for 33.5% of its USD- and Euro- denominated bank loans outstanding as of December 31, 2013.

The following table presents the fair value of the Group's derivative instruments designated as hedges in the consolidated statements of financial position as of December 31, 2013 and 2012.

The following table presents the effect of the Group's derivative instruments designated as hedges in the consolidated statements of operations and comprehensive income for the years ended December 31, 2013, 2012 and 2011. The amounts presented include the ineffective portion of derivative instruments and the amounts reclassified into earnings from accumulated other comprehensive income.

The following table presents the amount of ineffective portion of Group's derivative instruments designated as hedges in the consolidated statements of operations and comprehensive income for the years ended December 31, 2013, 2012 and 2011.

In May 2013, the Group repaid the full amount due under the HSBC bank credit facility granted to MTS OJSC in 2004 with an original maturity in November 2013. The voluntary prepayment of principal and interest in the amount of RUB 102 million ($3.2 million) resulted in an immediate termination of the hedging relationship between designated interest rate swap agreements and the credit facility.

In May 2013, the Group repaid the full amount due under the Citibank credit facility granted to MTS OJSC in 2005 with an original maturity in May 2014. The voluntary prepayment of principal and interest in the amount of RUB 686 million ($21.8 million) resulted in an immediate termination of the hedging relationship between designated interest rate swap agreements and the credit facility.

In April 2013, the Group repaid the full amount due under the HSBC bank credit facility granted to MTS OJSC in 2004 with an original maturity in October 2013. The voluntary prepayment of principal and interest of RUB 132 million ($4.2 million) resulted in an immediate termination of the hedging relationship between designated interest rate swap agreements and the credit facility.

In March 2013, the Group repaid the full amount due under the HSBC bank credit facility granted to MTS OSJC in 2004 with an original maturity in September 2013. The voluntary prepayment of principal and interest in the amount of RUB 276 million ($8.9 million) resulted in an immediate termination of the hedging relationship between designated interest rate swap agreements and the credit facility.

In February 2011, the Group repaid the full amount due under the Barclays bank credit facility granted to MTS OJSC in 2005 with an original maturity in 2014. The voluntary prepayment of principal and interest in the amount of RUB 1,373 million ($46.3 million) resulted in an immediate termination of the hedging relationship between designated interest rate swap agreements and the credit facility.

After the termination of hedging relationships any amounts accumulated in other comprehensive income and associated with the prepaid debt have been reclassified into earnings, going forward those derivatives are marked to market through earnings.

The following table presents the amount of accumulated other comprehensive loss reclassified into earnings during the years ended December 31, 2013, 2012 and 2011 due to termination of hedging relationships.

The following table presents the effect of the Group's interest rate swap agreements designated as hedges in accumulated other comprehensive income for the years ended December 31, 2013, 2012 and 2011.

As of December 31, 2013, the outstanding hedging instruments were highly effective. Approximately RUB 322 million of net loss is expected to be reclassified into net income during the next twelve months.

Cash inflows and outflows related to hedging instruments were included in cash flows from operating and financing activities in the consolidated statements of cash flows for the years ended December 31, 2013, 2012 and 2011.

Foreign currency options—In 2010 and 2009, the Group entered into foreign currency option agreements to manage the exposure to changes in currency exchange rates related to USD-denominated debt obligations. According to the agreements, the Group had a combination of put and call option rights to acquire $330.0 million (RUB 10,022 million) at rates within a range specified in contracts. These contracts were not designated for hedge accounting purposes. These currency option agreements matured in 2012.

The following table presents the effect of the Group's derivative instruments not designated as hedges on the consolidated statements of operations and comprehensive income for the years ended December 31, 2013, 2012 and 2011.

The Group measured assets and liabilities associated with derivative agreements at fair value Level 2 on a recurring basis. There were no assets and liabilities associated with derivative agreements measured at fair value Level 1 and Level 3 as of December 31, 2013 and 2012 (Note 2 and 19).

The following fair value hierarchy table presents information regarding the Group's assets and liabilities associated with derivative agreements as of December 31, 2013 and 2012:

According to U.S. GAAP requirements the Group records derivative instruments, redeemable noncontrolling interest, contingent consideration and investment in a mutual investment fund at fair value on a recurring basis.

The following tables summarize those assets and liabilities measured at fair value on a recurring basis:

Changes in the Group's net assets and earnings resulted from fair value measurements of Level 3 assets and liabilities were not significant for the years ended December 31, 2013 and 2012. There were no realized and unrealized gains and losses on Level 3 assets and liabilities for the years ended December 31, 2013 and 2012.

The fair value measurement of the Group's derivative instruments is based on the observable yield curves for similar instruments. The redeemable noncontrolling interest was measured at fair value using a discounted cash flow technique. The fair value of contingent consideration was determined as the best estimate of all possible outcomes of the contingency. The inputs are based on all available internal and external information, including growth projections and industry experts' estimates, where applicable.

The most significant quantitative inputs used to measure the fair value of redeemable noncontrolling interest as of December 31, 2013 and 2012 are presented in the table below:

There were no transfers between levels within the hierarchy for the years ended December 31, 2013 and 2012.

In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Group records assets and liabilities at fair value on a nonrecurring basis. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. No impairment charges were recognized in the consolidated statements of operations and comprehensive income for the year ended December 31, 2013. The losses recognized on assets measured at fair value on a nonrecurring basis for

the year ended December 31, 2012 are summarized below. In 2013, these losses were assigned to discontinued operations (Note 4):

As of December 31, 2012, the fair value of the impaired property, plant and equipment, other intangible assets, licenses and goodwill amounted to RUB 7,782 million, RUB 1,558 million, nil and nil, respectively.

The Group used a probability-weighted valuation technique to determine the fair value of the long-lived assets. The fair value of long-lived assets was determined based on unobservable inputs ("Level 3" of the hierarchy established by the U.S. GAAP guidance). In calculation of future cash flows for the assessment of the fair value of long-lived assets the Group used forecasts of Uzbekistan telecommunication market and Uzdunrobita's position on that market. The forecasts were based on all available internal and external information, including growth projections and industry experts' estimates.

The carrying amounts of cash and cash equivalents; short-term investments; accounts receivable; accounts payable and accrued expenses approximate their fair values because of the relatively short-term maturities of these financial instruments.

The fair value of notes payable is estimated based on quoted prices for those instruments ("Level 1" of the hierarchy established by the U.S. GAAP guidance). As of December 31, 2013 and 2012, the fair value of notes payable, including the current portion, amounted to RUB 106,668 million and RUB 86,657 million, respectively.

The fair value of bank loans and other debt is estimated using discounted cash flows and market-based expectations for interest rates, credit risk and the contractual terms of the debt instruments ("Level 2" of the hierarchy established by the U.S. GAAP guidance). As of December 31, 2013 and 2012, the fair value of bank loans and other debt, including the current portion, approximates their carrying value and amounted to RUB 116,356 million and RUB 151,323 million, respectively.

Provision for income taxes for the years ended December 31, 2013, 2012 and 2011 was as follows:

The statutory income tax rates in jurisdictions in which the Group operates for the fiscal years of 2013, 2012 and 2011 were as follows: Russia, Armenia—20.0%, Turkmenistan—8.0%. During the years ended December 31, 2013, 2012 and 2011 the Ukraine tax rate was 19.0%, 21.0% and 23.0%, respectively. For the year ended December 31, 2014 the Ukraine tax rate is 18.0% and it is expected to decrease to 17.0% and 16.0% for the years ended December 31, 2015 and 2016, respectively.

The Russia statutory income tax rate reconciled to the Group's effective income tax rate for the years ended December 31, 2013, 2012 and 2011 was as follows:

The Group has the following significant balances for income tax losses carryforward and related operating losses as of December 31, 2013 and 2012:

Management established the following valuation allowances against deferred tax assets where it was more likely than not that some portion of such deferred tax assets will not be realized:

The following table summarizes the changes in the allowance against deferred tax assets for the years ended December 31, 2013, 2012 and 2011:

For the remaining balances for income tax losses carryforward realization is dependent on generating sufficient taxable income prior to expiration of the losses carryforward. Although realization is not assured, management believes that it is more likely than not that all of the deferred tax asset will be realized. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced.

As of December 31, 2013 and 2012, the Group recognized deferred income tax liabilities of RUB 2,511 million and RUB 1,653 million, respectively, for income taxes on future dividend distributions from foreign subsidiaries (MTS Ukraine and K-Telecom) which are based on RUB 36,245 million and RUB 34,420 million cumulative undistributed earnings of those foreign subsidiaries in accordance with local statutory accounting regulations (unaudited) because such earnings are intended to be repatriated.

The following table represents changes in the balances of accumulated other comprehensive loss by components for the year ended December 31, 2013:

Dividends—In 2013, the Board of Directors approved a dividend policy, whereby the Group shall aim to make minimum dividend distribution payments to shareholders for the calendar years 2013-2015 in the amount equal to at least 75% of Free cash flow for the relevant financial period or, if greater, RUB 40.0 billion per year. Free cash flow is defined by cash flows from operating activities less cash paid (received) for acquisition or disposal of property, plant and equipment, intangible assets and other adjustments.

The dividend can vary depending on a number of factors, including the outlook for earnings growth, capital expenditure requirements, cash flows from operations, potential acquisition opportunities, as well as the Group's debt position.

The Group may take decisions on dividend payout based not only on financial year-end results but also based on interim results for three, six or nine months of the fiscal year. Annual dividend payments, if any, must be recommended by the Board of Directors and approved by the shareholders.

In accordance with Russian laws, earnings available for dividends are limited to profits determined under Russian statutory accounting regulations, denominated in Russian Rubles, after certain deductions. The net income of MTS OJSC for the years ended December 31, 2013, 2012 and 2011 that is distributable under Russian legislation totaled RUB 55,999 million (unaudited), RUB 42,949 million and RUB 54,129 million, respectively.

The following table summarizes the Group's declared cash dividends in the years ended December 31, 2013, 2012 and 2011:

As of December 31, 2013 and 2012, dividends payable were RUB 57.0 million and RUB 70.0 million, respectively.

MGTS' preferred stock—MGTS, a subsidiary of MTS, had 15,574,492 preferred shares outstanding at December 31, 2013 and 2012. In June 2012, the General shareholders' meeting of MGTS approved the reorganization of MGTS in a form of spin-off of MGTS-N JSC, a newly established wholly-owned subsidiary, and a merger of both MTS-P JSC, a subsidiary of MTS, and UTS-MGTS JSC with MGTS. In September 2012, the Group completed the MGTS' shares buyback related to this reorganization. A total of 82,891 common and 391,358 preferred shares of MGTS were repurchased for RUB 260.8 million.

MGTS' preferred shares carry guaranteed non-cumulative dividend rights amounting to the higher of (a) 10% of MGTS' net profit as determined under Russian accounting regulations and (b) the dividends paid on common shares. No dividends may be declared on common shares before dividends on preferred shares are declared. If the preferred dividend is not paid in full in any year the preferred shares also obtain voting rights, which will lapse after the first payment of the dividend in full. Otherwise, preferred shares carry no voting rights except on resolutions regarding liquidation or reorganization of MGTS and changes / amendments to MGTS' charter restricting the rights of holders of preferred shares. Such resolutions require the approval of 75% of the preferred shareholders. In the event of liquidation, dividends to preferred shareholders that have been declared but not paid have priority over ordinary shareholders.

In June 2013 and 2012, at MGTS' annual shareholders meeting the decision was made not to pay dividends on preferred shares for 2012 and 2011. Therefore the holders of preferred shares obtained voting rights.

In May 2011, MGTS' annual shareholders meeting approved dividends on ordinary and preferred shares totaling RUB 18,961 million for 2010. As of December 31, 2013 and 2012, dividends payable were RUB 48.6 and RUB 63.8 million, respectively.

In September 2007, the Group acquired an 80% stake in International Cell Holding Ltd, the 100% indirect owner of K-Telecom, Armenia's mobile phone operator, and signed a call and put option agreement to acquire the remaining 20% stake. In December 2010, the Group signed an amendment to the put and call option agreement. According to the amended option agreement, the price for the remaining 20% stake option will be determined by an independent investment bank subject to a cap of EUR 200 million. The put option can be exercised during the period from the next business day following the date of settlement of all liabilities under the loan agreement (Note 14) up to December 31, 2016. The call option can be exercised during the period from July 1, 2010 up to December 31, 2016. If both the call notice and the put notice are served on the same day then the put notice shall be deemed exercised in priority to the call notice. The noncontrolling interest was measured at fair value using a discounted cash flow technique and amounted to RUB 2,932 million and 2,298 million as of December 31, 2013 and 2012, respectively (Note 19). The fair value was determined based on unobservable inputs ("Level 3" of the hierarchy established by the U.S. GAAP guidance).

General and administrative expenses for the years ended December 31, 2013, 2012 and 2011 comprised the following:

In 2012, the Group aligned its business into three reportable segments of Russia, Ukraine and Uzbekistan based on the business activities in different geographical areas to effectively manage both the mobile and the fixed line operations as an integrated business. The Russian reportable segment arose due to the aggregation of two similar operating segments: MTS Russia and MGTS Russia.

In 2013, the results of operations of Uzbekistan are reported as discontinued operations in the accompanying consolidated statements of operations and comprehensive income for all periods presented. The segment reporting for the years ended December 31, 2012 and 2011 was restated accordingly. The statement of financial position was not retrospectively restated and therefore as of

December 31, 2012 captions of statement of financial position in the "Other" category include Uzbekistan.

The Group provides a wide range of mobile and fixed line voice and data telecommunications services in Russia and Ukraine, including transmission, broadband, pay TV and various value-added services, i. e. both mobile and fixed line services to customers across multiple regions.

Other unallocated expenses such as interest (income) / expense, equity in net income of associates, other (income) / expenses and currency exchange and transaction loss / (gain) are shown for purposes of reconciling the Group's segment measure, net operating income, to the Group's consolidated total for each of the periods presented.

Capital commitments—As of December 31, 2013, the Group had executed purchase agreements of approximately RUB 34,728 million to acquire property, plant and equipment, intangible assets and costs related thereto.

Operating leases—The Group has entered into non-cancellable agreements to lease space for telecommunications equipment, offices and transmission channels, which expire in various years up to 2068. Rental expenses under the operating leases of RUB 14,677 million, RUB 13,334 million and RUB 11,297 million for the years ended December 31, 2013, 2012 and 2011, respectively, are included in operating expenses in the accompanying consolidated statements of operations and comprehensive income. Rental expenses under the operating leases of RUB 7,583 million, RUB 7,207 million and RUB 6,720 million for the years ended December 31, 2013, 2012 and 2011, respectively, are included in cost of services in the accompanying consolidated statements of operations and comprehensive income.

Future minimum lease payments due under these leases for the five years ending December 31, 2018 and thereafter are as follows:

Taxation—Russia and the CIS countries currently have a number of laws related to various taxes imposed by both federal and regional governmental authorities. Applicable taxes include VAT, corporate income tax (profits tax), a number of turnover-based taxes, and payroll (social) taxes. Laws related to these taxes have not been in force for significant periods, in contrast to more developed market economies; therefore, the government's implementation of these regulations is often inconsistent or nonexistent. Accordingly, few precedents with regard to tax rulings have been established. Tax declarations, together with other legal compliance areas (for example, customs and currency control matters), are subject to review and investigation by a number of authorities, which are enabled by law to impose extremely severe fines, penalties and interest charges. These facts create tax risks in Russia and the CIS countries that are more significant than those typically found in countries with more developed tax systems.

Generally, according to Russian and Ukrainian tax legislation, tax declarations remain open and subject to inspection for a period of three years following the tax year. As of December 31, 2013, tax declarations of MTS OJSC and other subsidiaries in Russia and Ukraine for the preceding three fiscal years were open for further review.

In December 2010, the Russian tax authorities completed a tax audit of MTS OJSC for the years ended December 31, 2007 and 2008. Based on the results of this audit, the Russian tax authorities determined that RUB 353.9 million in additional taxes, penalties and fines were payable by the Group. The resolution did not come into force as the Group prepared and filed a petition with the Federal Tax Service to declare the tax authorities' resolution to be invalid. In September 2011, the Federal Tax Service partially satisfied the Group's petition, decreasing the amount of additional taxes, penalties and fines payable by the Group by RUB 173.9 million. The Group filed an appeal for RUB 84.2 million of the remaining RUB 180.0 million with the Moscow Arbitrate Court. In August 2013, the Moscow Arbitrate Court issued a ruling to partly grant the Group's claim, which was subsequently confirmed by the Arbitrate Appeal Court in November 2013. However, the Group appealed the decision of the Arbitrate Appeal Court in the Federal Arbitrate Court of Moscow District, which issued a ruling to partly grant the Group's claim in March 2014. The Group is considering its further actions.

In June 2013, the Russian tax authorities completed a tax audit of MTS OJSC for the years ended December 31, 2009, 2010 and 2011. Based on the results of this audit, the Russian tax authorities determined that RUB 253.4 million in additional taxes, penalties and fines were payable by the Group. The claim was accrued in full amount in the consolidated financial statements for the year ended December 31, 2013 and final amounts due were paid in January 2014. In December 2013, the Group appealed the resolution of this assessment to the Federal Tax Service, and, further to its refusal to grant the appeal, the Group is considering appealing to the Moscow Arbitrate Court.

The Group purchases supplemental software from foreign suppliers of telecommunications equipment in the ordinary course of business, which is subject to customs regulation. In addition pricing of revenue and expenses between each of the Group's subsidiaries and various discounts and bonuses to the Group's subscribers in the course of performing its marketing activities may be subject to transfer pricing rules. Management believes that it has adequately provided for tax and customs liabilities in the accompanying consolidated financial statements. As of December 31, 2013 and 2012, the provision accrued for taxes other than income tax and customs settlements amounted to RUB 2,278 million and RUB 804 million, respectively. In addition, the accrual for unrecognized income tax benefits, potential penalties and interest recorded in accordance with the authoritative guidance on income taxes totaled RUB 615 million and RUB 471 million as of December 31, 2013 and 2012, respectively. However, the risk remains that the relevant tax and customs authorities could take differing positions with regard to interpretive issues and the effect could be significant.

3G license—In May 2007, the Federal Service for Supervision in the Area of Communications and Mass Media awarded MTS a license to provide 3G services in the Russian Federation. The 3G license was granted subject to certain capital and other commitments. The major conditions are that the Group is required to (i) build a certain number of base stations that support 3G standards, (ii) have commenced providing services in Russia by a certain date, and (iii) build a certain number of base stations by the end of the third, fourth and fifth years from the date of granting the license. Management believes that as of December 31, 2013 the Group is in compliance with these conditions.

LTE license—In July 2012, the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media allocated MTS the necessary license and frequencies to provide LTE telecommunication services in Russia. Under the terms and conditions of the LTE license, the Group is obligated to fully deploy LTE networks within seven years, commencing from January 1, 2013, and deliver LTE services in each population center with over 50,000 inhabitants in Russia by 2019. Also, the Group is obligated to invest at least RUB 15 billion annually toward the LTE roll-out until the network is fully deployed. Management believes that as of December 31, 2013 the Group is in compliance with these conditions.

Bitel—In December 2005, MTS Finance acquired a 51.0% stake in Tarino Limited ("Tarino"), from Nomihold Securities Inc. ("Nomihold"), for RUB 4,322 million ($150.0 million at exchange rate for December 2005) in cash based on the belief that Tarino was at that time the indirect owner, through its wholly owned subsidiaries, of Bitel LLC ("Bitel"), a Kyrgyz company holding a GSM 900/1800 license for the entire territory of Kyrgyzstan.

Following the purchase of the 51.0% stake, MTS Finance entered into a put and call option agreement with Nomihold for the remaining 49.0% interest in Tarino shares and a proportional interest in Bitel shares ("Option Shares"). The call option was exercisable by MTS Finance from November 22, 2005 to November 17, 2006, and the put option was exercisable by Nomihold from November 18, 2006 to December 8, 2006. The call and put option price was RUB 4,898 million ($170.0 million at exchange rate for December 2005).

Following a decision of the Kyrgyz Supreme Court on December 15, 2005, Bitel's corporate offices were seized by a third party. As the Group did not regain operational control over Bitel's operations in 2005, it accounted for its 51.0% investment in Bitel at cost as at December 31, 2005. The Group appealed the decision of the Kyrgyz Supreme Court in 2006, but the court did not act within the time period permitted for appeal. The Group subsequently sought the review of this dispute over the ownership of Bitel by the Prosecutor General of Kyrgyzstan to determine whether further investigation could be undertaken by the Kyrgyz authorities.

In January 2007, the Prosecutor General of Kyrgyzstan informed the Group that there were no grounds for involvement by the Prosecutor General's office in the dispute and that no legal basis existed for the Group to appeal the decision of the Kyrgyz Supreme Court. Consequently, the Group wrote off the costs relating to the purchase of the 51.0% stake in Bitel, which was reflected in its annual consolidated financial statements for the year ended December 31, 2006. Furthermore, with the impairment of the underlying asset, a liability of RUB 4,476 million ($170.0 million as of December 31, 2006) was recorded with an associated charge to non-operating expenses.

In November 2006, MTS Finance received a letter from Nomihold purporting to exercise the put option and sell the Option Shares for RUB 4,526 million ($170.0 million at exchange rate for November 2006) to MTS Finance. In January 2007, Nomihold commenced an arbitration proceeding against MTS Finance in the London Court of International Arbitration ("LCIA") in order to compel MTS Finance to purchase the Option Shares. Nomihold sought specific performance of the put option, unspecified monetary damages, interest, and costs. In January 2011, LCIA made an award in favor of Nomihold satisfying Nomihold's specific performance request and ordered MTS Finance to pay to Nomihold the award ("Award") including RUB 5,115 million ($170.0 million at exchange rate for January 2011) for the Option Shares and RUB 178 million ($5.9 million at exchange rate for January 2011) in damages, bearing interest until Award is satisfied. In addition to the RUB 4,476 million ($170.0 million as of December 31, 2006) liability related to this case and accrued in the year ended December 31, 2006, the Group recorded an additional loss in the amount of RUB 224 million ($7.2 million at exchange rate for the year ended December 31, 2012), RUB 94 million ($3.2 million at exchange rate for the year ended December 31, 2011) and RUB 1,239 million ($40.8 million at exchange rate for the year ended December 31, 2010) in the consolidated financial statements for the years ended December 31, 2012, 2011, and 2010, respectively, representing damages, other costs and interest accrued on the awarded sums. The total liability accrued amounted to RUB 7,236 million ($221 million as of June 22, 2013).

On January 26, 2011, Nomihold obtained a freezing order in respect of the Award from the English High Court of Justice which, in part, restricted MTS Finance from dissipating its assets.

Additionally, MTS Finance was granted permission to appeal the Award, but the Appeal Court imposed conditions upon the appeal. MTS Finance sought to have the conditions lifted, however, the Supreme Court of England upheld the decision of the Appeal Court.

Further on February 1, 2011, Nomihold obtained an order of the Luxemburg District Court enforcing the Award in Luxembourg. This order was appealed by MTS Finance.

As an issuer of RUB 11,201 million ($400.0 million as of January 28, 2005) Notes due 2012 pursuant to an Indenture dated January 28, 2005 (as amended) ("the Notes"), MTS Finance was due to redeem the principal of the Notes and pay the final coupon payment on January 30, 2012. However as a result of the freezing order, MTS OJSC applied to and obtained from the English Court an order authorizing both payments to be made by MTS OJSC rather than MTS Finance ("the Direct Payments"). The Direct Payments to noteholders by the trustee under the Indenture were made on or around January 28, 2012.

The Direct Payments were made despite an obligation under an intercompany loan agreement dated January 28, 2005 between MTS OJSC and MTS Finance ("the Intercompany Loan Agreement") to process the payments through MTS Finance. However, because MTS Finance was subject to a freezing order and not capable of transferring funds to the trustee for distribution and because MTS OJSC owed obligations to the noteholders as guarantor under the Indenture, MTS OJSC made the Direct Payments to the noteholders pursuant to an order of the English Court.

In relation to the obligations under the Intercompany Loan Agreement, MTS OJSC and MTS Finance have agreed to refer to arbitration under the Rules of LCIA the question of whether under the Intercompany Loan Agreement itself there remains an obligation to make any further payments to MTS Finance in light of the Direct Payments. On February 9, 2012, MTS OJSC received a request for arbitration from MTS Finance. The hearing took place at the end of January 2013.The award has clarified the rights between the parties under the Intercompany Loan Agreement. MTS OJSC was denying that any further payments were due under the Intercompany Loan Agreement. The arbitration was conducted under the Rules of LCIA.

In March 2013, Nomihold obtained initial permission from the English Commercial Court to serve proceedings out of the jurisdiction on MTS. Nomihold purported that MTS was liable to compensate it for a number of allegedly tortious wrongs, relating in part to recent proceedings in an international arbitration tribunal constituted under the rules of LCIA between Nomihold and MTS Finance, in the total amount exceeding RUB 6,662 million ($215 million at exchange rate for March 2013). MTS denied any allegation of wrongdoing and considered the claims made by Nomihold without merit and inadmissible before the English courts.

In addition, three Isle of Man companies affiliated with the Group (the "KFG Companies"), were named as defendants in lawsuits filed by Bitel in the Isle of Man seeking the return of dividends received from Bitel by these three companies in the first quarter of 2005 in the amount of approximately RUB 776 million ($25.2 million at exchange rate for March 2013) plus compensatory damages, and to recover approximately RUB 114 million ($3.7 million at exchange rate for March 2013) in losses and accrued interest.

In January 2007, the KFG Companies asserted counterclaims against Bitel, and claims against other defendants, including Altimo LLC ("Altimo"), Altimo Holdings & Investments Limited ("Altimo Holdings"), CP-Crédit Privé SA and Fellowes International Holdings Limited, for the wrongful misappropriation and seizure of Bitel. The defendants sought to challenge the jurisdiction of the Isle of Man courts to try the counterclaims asserted by the KFG Companies.

On March 10, 2011, the Judicial Committee of the UK Privy Council ruled in favor of the KFG Companies and confirmed the jurisdiction of the Isle of Man courts to try the counterclaims asserted by the KFG Companies against various defendants, including Sky Mobile, Altimo and Altimo Holdings, for the wrongful misappropriation and seizure of Kyrgyz telecom operator Bitel and its assets.

On June 30, 2011, the KFG Companies obtained from the Isle of Man court a general asset freezing injunction over the assets of Altimo and Altimo Holdings. The general freezing injunction against Altimo Holdings was replaced on November 30, 2011 by a specific freezing injunction over (i) Altimo Holding's interest in its Dutch subsidiary, Altimo Coöperatief U.A., and (ii) VimpelCom common shares worth RUB 15,661 million ($500 million as of November 30, 2011) (in April 2013 increased to RUB 28,197 million ($900 million at exchange rate for April 2013)) that Altimo Coöperatief U.A. has lodged with the Isle of Man court. The KFG Companies were proceeding with their counterclaims in the Isle of Man.

In a separate arbitration proceeding initiated against the KFG Companies by Kyrgyzstan Mobitel Investment Company Limited ("KMIC"), under the rules of LCIA, the arbitration tribunal in its award found that the KFG Companies breached a transfer agreement dated May 31, 2003 (the "Transfer Agreement"), concerning the shares of Bitel. The Transfer Agreement was made between the KFG Companies and IPOC International Growth Fund Limited ("IPOC"), although IPOC subsequently assigned its interest to KMIC, and KMIC was the claimant in the arbitration. The tribunal ruled that the KFG Companies breached the Transfer Agreement when they failed to establish a date on which the equity interests in Bitel were to be transferred to KMIC and by failing to take other steps to transfer the Bitel interests. This breach occurred prior to the acquisition of the KFG Companies by MTS Finance. The arbitration tribunal ruled that KMIC is entitled only to damages in an amount to be determined in future proceedings. At the request of the parties, the tribunal agreed to stay the damages phase of the proceedings pending conclusion of the Isle of Man proceedings.

In June 2013, an agreement was reached between Altimo, Altimo Holdings, MTS OJSC, MTS Finance, Nomihold and other associated parties to settle all disputes that have arisen from investments in Bitel ("the Agreement"). The Agreement covers matters involving a number of parties and legal proceedings, including those in the Isle of Man, London, Luxembourg and other jurisdictions. Pursuant to the Agreement all proceedings between the parties and their associated parties have been discontinued and waived, and MTS OJSC received a total payment of RUB 4,909 million ($150 million at exchange rates at the dates of payments) ("Settlement Payment"). All parties made the necessary submissions to the respective courts and tribunals to document the settlement, which, among other actions, fully discharged any and all outstanding obligations under the Award rendered by LCIA against MTS Finance in January 2011, as well as settled the tripartite LCIA arbitration between MTS OJSC,

MTS Finance and Nomihold and a tort action filed by Nomihold against MTS OJSC in the English Courts.

The Group released provision of RUB 7,236 million ($221 million), comprising RUB 5,566 million ($170 million) set by LCIA to exercise the put option for acquisition of the remaining 49% stake in Bitel plus RUB 1,670 million ($51 million) in damages, interest and other costs that had been provided for in relation to the dispute with Nomihold. The release of the provision was recognized as non-operating income in the accompanying consolidated statements of operations and comprehensive income for the year ended December 31, 2013, being the same line item through which the initial charge was taken.

The Group recognized a gain of RUB 4,911 million ($150 million) with respect to the Settlement Payment in the consolidated statement of operations and comprehensive income for the year ended December 31, 2013, of which RUB 1,060 million ($32.4 million) was recognized as operating income, and RUB 3,851 million ($117.6 million) as non-operating income on a pro-rata basis with respect to the expenses previously incurred and recognized in relation to the Bitel dispute.

Litigation in Ukraine—In August 2012, the Group received from MTS LLC, based in Ukraine, a claim regarding dismissal of international registration of four of the Group trademarks on the territory of Ukraine. The claim was fully dismissed by Economic Appeal Court of Kiev in December 2013. Since then, the Group expects no negative consequences.

Other litigation—In the ordinary course of business, the Group is a party to various legal, tax and customs proceedings, and subject to claims, certain of which relate to developing markets and evolving fiscal and regulatory environments in which MTS operates. Management believes that the Group's liability, if any, in all such pending litigation, other legal proceeding or other matters will not have a material effect upon its financial condition, results of operations or liquidity of the Group.

Political and economic crisis in Ukraine—Subsequent to year end, key aspects of the Ukrainian economy continued to deteriorate. Opposing groups have organized protests in Kyiv and other regions of the country. A referendum on the status of Crimea was held on March 16, 2014 followed by Crimea's acceding to the Russian Federation on March 21, 2014. These protests and the related unrest have caused a deterioration of Ukraine's credit ratings and depreciation of the national currency. The political tension in Ukraine remains high and in case of further escalation, conflict or imposition of any sanctions applicable to the Group's operations could result in a negative impact on our business in Ukraine including on its financial position and results of operations, and such impact, if any, could be significant.

Raising financing from Citibank Europe and Swedish Export Credit Corporation—On March 12, 2014, the Group entered in a credit facility agreement with Citibank Europe PLC and Swedish Export Credit Corporation for up to $300 million (RUB 10,920 million at the date of transaction). The credit facility will be used for the development of the Group's mobile networks through purchases of equipment from Ericsson. The facility will be made available in one tranche with maturity in July 2024. The interest rate

is LIBOR + 0.9%. The amounts may be drawn by the Company over the next 12 months and will be linked to equipment purchases for the development of LTE networks.

Depreciation of the Russian Ruble—During the period from December 31, 2013 to April 17, 2014, the Russian Ruble further depreciated by 10% and 11% against the U.S. Dollar and the Euro, respectively. Since a portion of the Group's capital expenditures, borrowings and certain operating costs are denominated in U.S. Dollars and Euros, this and any further devaluation could adversely affect the Group's results of operations in 2014. The Group would experience an estimated currency exchange loss of RUB 4.3 billion on its U.S. Dollar- and Euro- denominated net monetary liabilities as a result of a hypothetical 10% and 11% depreciation of the Russian Ruble against the U.S. Dollar and Euro at December 31, 2013, respectively. This sensitivity analysis includes only outstanding U.S. Dollar- and Euro- denominated monetary items.

Repurchase of Notes—In March 2014, the Group repurchased part of MTS International Notes due 2020 with nominal value of USD 50.2 million (RUB 1,819 million at the date of transaction).

Disposal of Business-Nedvizhimost—In April 2014, the Group sold a 49% stake in Business-Nedvizhimost to Sistema for cash consideration of RUB 3.1 billion to be paid by June 30, 2014. Before the disposal an ownership interest in Business-Nedvizhimost was held by MGTS-Nedvizhimost CJSC, a subsidiary of MGTS, and was accounted for by the Group using the equity method (Note 3).

Raising financing from Sberbank—On April 11, 2014 the Group signed an agreement with Sberbank to open a non-revolving credit line for a total amount of RUB 20 billion. The credit line matures in July 2015 and bears an annual interest rate of 9.96%. The line will be used to support general corporate needs.

Investigations into former operations in Uzbekistan—In March 2014, the Group received requests for the provision of information from the United States Securities and Exchange Commission and the United States Department of Justice relating to an investigation of the Group's former subsidiary in Uzbekistan (Note 4). As the aforementioned US government investigations are at an early stage, the Company cannot predict the outcome of the investigations, including any fines or penalties that may be imposed, and such fines or penalties could be significant.
