UK-UA: Reform Assistance Advisory Diagnostic analysis of receivables National Joint-Stock Company

Important notice This document has been prepared for National Joint-Stock Company (the Company or Naftogaz ) within the technical assistance provided by the UK Government under the UK-UA: Reform Assistance programme. The objective of this document is to assist Naftogaz with the analysis of its receivables due from the sale of gas as set out in the Memorandum signed by the Ukrainian Government and the International Monetary Fund (the IMF ) on 27 February 2015. The work has been carried out in accordance with the Terms of Reference dated 9 June 2015, agreed between Naftogaz and the IMF. Given this work is strongly supported by the IMF and is a key part of their jointly agreed programme with the Government of Ukraine, the IMF can be conceived of as a secondary beneficiary of this document.

Included in the gross amount of debt is UAH 2.9 bln of fines and penalties, which were accrued by the Group following positive decisions of courts. Complexity of the market Historically Naftogaz had limited visibility on amounts paid by the end user (e.g. households) and as such was reliant on the intermediaries to pass on funds, once they themselves had been paid. As such the Group was heavily dependent on the transparency and discretion of intermediaries (such as oblgases and heating companies) and the availability of national budget funds to cover any differences in tariffs and subsidies for the social vulnerable categories of population (e.g., pensioners). The introduction of special accounts (whereby a proportion of payments from end users is transferred directly to Naftogaz) has partially remedied the situation, although they have only recently been introduced for heating companies. 2

Section 1 Executive Summary Summary of key issues (2 of 3) Observation Highly regulated environment Legal work-out Comment Under the appropriate legislation Naftogaz is defined as a guaranteed supplier of gas and as such it is required to enter new contracts with customers despite the failure to pay for earlier gas supplies. However, the standard contractual terms of Naftogaz allow them to limit or terminate supply of gas or even terminate the respective contracts, if there is an unsettled overdue debt. Management commented that the clause on limiting or terminating the gas supply is regularly applied by the Company. However, historically Naftogaz did not terminate the contracts and the first cases where Naftogaz has applied this clause are currently being challenged by the customers. The respective court decisions are pending. Since 2005, legally the Group cannot enforce temporarily debt collection or bankruptcy for certain categories of customers (further details are provided below). In addition, legislation was introduced in 2011 which imposed a write off of some debts for gas supplied prior to 2010 and a restructuring of debts for gas supplied in 2010. As a result, the Group wrote off UAH 10,428 mln of debts and restructured UAH 3,765 mln (payable in instalments over a period of 20 years). Similar legislation was adopted in May 2015, leading to potential write-off of fines and penalties for the debts of heating companies which were accumulated prior to 2014, provided the principal is paid, and restructuring of debts which originated in 2014 (payable in instalments over a 2 year period). According to the information provided by the Group s Legal Departments, the Group is currently managing approximately 5 thousand cases in relation to debts for the sale of gas starting from 2010. The total claims since 2010 amount to UAH 49.5 bln, including UAH 38.8 bln of principal and UAH 10.7 bln of fines and penalties. Included in the court decisions in favour of Naftogaz are cases totalling UAH 2.5 bln, enforcement of which is currently suspended, mainly under legislative provisions of the Law of Ukraine On Measures Aimed At Ensuring Functioning of Enterprises of Fuel and Energy Sector No.2711-IV dated on 23 June 2005 (with the major impact on the debts due from the heating companies). In order to decrease the volume of court cases and make the process more efficient, legal actions to collect debts are delayed until contact expiry, while initiation of the claim to be filed is at discretion of the responsible person. In some cases, claims are filed before the expiry of the contract (e.g., when a risk of insolvency has been identified). 3

Section 1 Executive Summary Summary of key issues (3 of 3) Observation Legal work-out (continued) Information on the business groups and beneficial owners Receivables from customers in Crimea and ATO zone Next steps Comment There appears to be limited monitoring of the actual cash payment resulting from the debt collection enforced by the court decision. In addition, the actual enforcement is dependent on the State Enforcement Service and is not controlled by the Group. Large number of cases is managed in regional courts due to specific legislation norms, which causes additional pressure on timing of claims and resources of the Group. There is currently no legal requirement for Naftogaz to ask for this information and their internal regulations do not require it, and as such this information is not maintained on file. Under the new legislation which becomes effective in September 2015, companies are required to disclose information on their beneficial owners and provide such information to the State Registrar. For the purposes of our analysis, we have reviewed records of the public database (smida.gov.ua) and IFRS financial statements (where publicly available) for the debtors with balances over UAH 50 mln to identify any information related to shareholders. This by itself does not confirm who the beneficial owners are (with the exception of one company). The results of our analysis are presented in Section 5. As of 31 December 2014, UAH 10.4 bln was due from customers located in annexed Crimea and ATO zone. In addition, UAH 3.8 bln was due from customers located in close proximity to the ATO zone. According to management, since February 2015 the Group terminated the gas supply to customers located within the ATO, and no supplies are expected going forward, until the conflict is resolved or respective decision to renew the supply is taken by the Ukrainian Government. Nevertheless this issue requires monitoring from the Company s management to avoid any debt enlargement. We will work with the Group over the coming period to develop new collection targets and recommendations to improve and monitor the Group s historic debt recovery and ongoing collection performance. 4

Section 2 Background of the Group s activities and regulations Debt collection of the Group is highly impacted by regulations (1 of 3) Key legislative acts that historically have had a significant impact on the Group s debt collection performances are discussed below: Law No.2711-IV On Measures Ensuring Functioning of Enterprises of the Fuel and Energy Sector adopted by the Parliament on 23 June 2005, the main objective of which was to protect state-owned assets in the energy sector from misappropriation. This Law introduced a ban on bankruptcy and forced debt collection against participants in the fuel and gas market, including heating companies and regional gas distribution companies. Resolution No.705 of the Cabinet of Ministers of Ukraine dated 25 July 2012, which defined Naftogaz and regional gas distribution companies as guaranteed suppliers of gas. On 3 October 2012, the Cabinet of Ministers by its Resolution No.939 obliged Naftogaz to supply gas to guaranteed suppliers of gas, i.e. regional gas distribution companies. Law No. 3319-VI On Debts for Consumed Natural Gas and Electrical Energy adopted by the Parliament on 12 May 2011, which resulted in a partial write-off and restructuring of debts of some customers of Gas of Ukraine (heating companies and regional gas distribution companies). In particular, debts which originated prior to 2010 were written off and debts accrued during 2010 were restructured. Timelines of key legislative changes 1998 establishment of the Group with Gas of Ukraine as the main trader of gas 2008 introduction of special accounts for regional gas distribution companies and traders of gas 2011 transfer of trading operations from Gas of Ukraine to Naftogaz Law On Write-off and Restructuring of Debts for Consumed Gas 2014 introduction of special accounts for heating and industrial companies May 2015 Law On Stabilization Of Financial Standing Of Naftogaz introduction of special accounts for heating companies which produce electricity using gas 2005 ban on bankruptcy and forced debt collection, inter alia, in respect of the heating companies and regional gas distribution companies 2010 Law On Principles Of Functioning Of Natural Gas Market 2012 introduction of new algorithm for special accounts guaranteed suppliers of natural gas are established March 2015 changes to special accounts algorithm for heating companies April 2015 Law On Natural Gas Market 7

Section 2 Background of the Group s activities and regulations Debt collection of the Group is highly impacted by regulations (2 of 3) On 14 May 2015, the Parliament adopted Law No. 423-VIII On Stabilization of Financial Standing of Naftogaz. Under this Law debt of the heating companies for the natural gas consumed in 2014 (excluding fines, late payment interest and inflation compensation), which is outstanding as of 6 June 2015, is subject to restructuring and will be repaid in instalments during a 24-month period. Such restructuring is possible only if companies repay their debts (excluding fines, late payment interest and inflation compensation) for the gas consumed prior to 2014. In this case, fines, late payment interest and inflation compensation will be written off. In addition, according to Law No. 423-VIII, Naftogaz and Gas of Ukraine may sell their debts for the supply of gas via auctions (at a discount). The Law became effective from 6 June 2015 and its application in practice is untested. Special consideration in the regulations is made to the process for payments received by Naftogaz from the customers for gas consumed. Resolution No.247 adopted by the Cabinet of Ministers of Ukraine on 26 March 2008 which introduced special bank accounts for oblgases and traders of gas, where funds received from end consumers of gas were further automatically split between Naftogaz and gas transportation companies (Ukrtransgaz and oblgases) according to a complex formula (approved by the Resolution of the National Commission No.1529 dated 25 December 2008). Timelines of key legislative changes 1998 establishment of the Group with Gas of Ukraine as the main trader of gas 2008 introduction of special accounts for regional gas distribution companies and traders of gas 2011 transfer of trading operations from Gas of Ukraine to Naftogaz Law On Write-off and Restructuring of Debts for Consumed Gas 2014 introduction of special accounts for heating and industrial companies May 2015 Law On Stabilization Of Financial Standing Of Naftogaz introduction of special accounts for heating companies which produce electricity using gas 2005 ban on bankruptcy and forced debt collection, inter alia, in respect of the heating companies and regional gas distribution companies 2010 Law On Principles Of Functioning Of Natural Gas Market 2012 introduction of new algorithm for special accounts guaranteed suppliers of natural gas are established March 2015 changes to special accounts algorithm for heating companies April 2015 Law On Natural Gas Market 8

Section 2 Background of the Group s activities and regulations Debt collection of the Group is highly impacted by regulations (3 of 3) On 2 August 2012, the formula was amended by Resolution No.1000 of the National Commission. According to management, the new formula did not allow Naftogaz to recover old debts, but only service the current portion of receivables. Similar accounts were introduced for industrial companies (Resolution No.23 issued by the National Commission on 16 January 2014) and for heating companies (Resolution No.217 issued by the Cabinet of Ministers of Ukraine on 18 June 2014 (effective from 4Q2014). The algorithm established by Resolution No.217 also envisaged repayment of old debts. Please note that by Resolution No.166 issued by the Cabinet of Ministers of Ukraine on 18 March 2015 changes to the special accounts algorithm were introduced which eliminated the possibility to recover the old debts, negatively effecting the recoverability of Naftogaz s accounts receivable. On 20 May 2015, the Cabinet of Ministers of Ukraine issued Decree No. 670-p introducing a new mechanism of settlements between electricity generating companies and the wholesale suppliers of electricity. This decree introduced the mechanism of special accounts in settlements with Naftogaz for the gas used by the heating/electricity generating companies for the production of electricity. Timelines of key legislative changes 1998 establishment of the Group with Gas of Ukraine as the main trader of gas 2008 introduction of special accounts for regional gas distribution companies and traders of gas 2011 transfer of trading operations from Gas of Ukraine to Naftogaz Law On Write-off and Restructuring of Debts for Consumed Gas 2014 introduction of special accounts for heating and industrial companies May 2015 Law On Stabilization Of Financial Standing Of Naftogaz introduction of special accounts for heating companies which produce electricity using gas 2005 ban on bankruptcy and forced debt collection, inter alia, in respect of the heating companies and regional gas distribution companies 2010 Law On Principles Of Functioning Of Natural Gas Market 2012 introduction of new algorithm for special accounts guaranteed suppliers of natural gas are established March 2015 changes to special accounts algorithm for heating companies April 2015 Law On Natural Gas Market 9

Section 3 Overview of receivables recovery process The Gas sales department oversees all interactions with customers from contract initiation to collection (1 of 2) Gas sales department Contractual work and gas sales division (9 people) Payments control division (18 people) Settlements and analytics division (8 people) Debt management division (16 people) Development of standard contract templates for gas sale Ensure any agreements with customers are concluded in accordance with the established procedures of Naftogaz Recording the actual volumes of natural gas consumed by undertaking acceptance procedures with customers Informing the Legal Department regarding execution of the enforcement documents by the debtors Preparation of gas sales registers and their submission to the Accounting Department to reflect gas sales transactions in the Company s accounts Daily analysis of received payments and receivable balances Daily forecast of cash flows from sales of gas Preparation of reports for management Daily analysis of payments received for the gas sold and payments by Naftogaz for transportation and distribution services (including posting respective entries in the automated system Navigator-IN (a system used by the Gas Sales Department to account for and analyse sales related operations and balances) Based on court decisions and respective accounting records, reflecting accruals and provisions relating to receivables and payables balances in Navigator-IN Preparation of materials on overdue debt, respective fines and penalties and their submission to the Legal Department to proceed with court filing Off-set arrangements Regular monitoring of official information on bankruptcy or liquidation procedures initiated in respect of the Company s debtors Consolidation of information on receivables and payables of the Company 12

Section 3 Overview of receivables recovery process The Gas sales department oversees all interactions with customers from contract initiation to collection (2 of 2) As a guaranteed supplier of natural gas, Naftogaz cannot refuse to conclude new gas supply contracts with its customers even if the latter have unpaid debts for gas supplied under old contracts. At the same time, according to the standard gas supply contracts with its customers, Naftogaz can limit or terminate supply of gas. The Company actively applies this contract clause in accordance with the Decree of the Cabinet of Ministers of Ukraine No1687 dated 8 June 2006 On Approval of Mechanism of Limiting (Terminating) Supply of Gas (Except for Population). Moreover the standard contractual terms allow Naftogaz to terminate the contract, if there is an unsettled overdue debt. According to management, they did not apply the contract termination clause until 2015, and as a result two court cases where initiated against Naftogaz (currently in progress). If Naftogaz successfully defends these cases, they will have an effective tool against problematic debtors. Before proceeding with the legal work-out, the Debt Management Division of the Gas Sales Department, conducts negotiations with individual debtors, reaching though regional authorities and trying to influence payment discipline of the debtors (through regular calls, official letters, etc.). Usually, Naftogaz files lawsuits against debtors to demand repayment of overdue debts and respective fines and penalties only after expiry of respective gas supply contracts. As such, the lawsuits cover only that portion of the debt which has not been paid after the contract expiry date (i.e., problematic debt). According to management, such approach helps the Group to decrease the number of claims to be filed and the volume of legal work. However, in cases where management identifies the risk that the principal debt may not be repaid, then the decision to file a court case is made before the contract expiry. There is no general practice of formal debt restructuring in the Group, unless there is a respective court decision or restructuring is initiated by the Parliament (see discussed earlier). 13

Section 3 Overview of receivables recovery process Overview of the main contractual terms of Naftogaz for supply of gas Contract duration Naftogaz concludes annual contracts for the supply of gas, using standard templates which are set by Nafogaz internally for each category of customers (i.e., industrial companies, oblgases (separately for supply of gas to households, heating companies, other entities), etc.). Per management, no changes to the standard contractual terms are usually allowed. Please note that the National Commission sets a standard template for the gas supply contract between owners of gas (e.g., Naftogaz) and oblgases which Naftogaz uses to prepare respective contract template with oblgases. Pricing Gas prices are regulated at each stage from exploration to supply to end consumers by the National Commission which sets either fixed prices (for supply of gas to households (through oblgases) as well as to heating companies for production and delivery of heat to households) or maximum level of prices (for other customers). Supply and payment terms Fines and penalties for overdue debt Contacts stipulate volume of gas to be supplied at a certain price on a monthly basis. Depending on the customer s category, the payment terms may vary from 30% monthly prepayment with the remaining balance payable in two equal instalments (i.e., 35% each) on the 5 th and 15 th day of the month of supply with final settlement to be made by the 14 th day of the next month (for industrial companies and other customers) to 1oo% payment for the planned volume of gas to be consumed in the month of supply (for oblgases and heating companies) with the final clearance on the 15 th (heating companies) or on the 20 th (oblgases) of the month following the month of supply. 1. Penalties (late payment interest) are calculated on a daily basis by multiplying the NBU s double discount rate and the amount of payments in arrears. 2. Fines is a one time fee set at 7% from overdue payment (only for supply of gas to industrial companies) 3. Inflation compensation 3% + inflation rate (as set by the State Statistics Service) multiplied by the amount of payment in arrears (on a daily basis). Termination clauses In case of overdue payments, according to the standard gas supply contracts (except for those with oblgases), Naftogaz has the right to limit/terminate supply of gas until the overdue payment is settled. 14

Section 3 Overview of receivables recovery process Overview of the legal work-out procedures in Naftogaz and Gas of Ukraine Our analysis was focused on Naftogaz and Gas of Ukraine, since these companies are mainly involved in the sale and purchase of gas and, as a result, are engaged in respective litigations. The Legal Department of Naftogaz includes about 50 specialists of which 31 are litigation specialists (20 of which participate in drafting and filing court claims, other staff are responsible for enforcement proceedings and bankruptcy cases). The Group s lawyers maintain special registers of the current court cases with indication of debtors, amount of debt, penalties applied for non-payment or late payment of the debt etc. If a customer has not paid for the supplied gas according to contractual terms, in most cases Naftogaz will initiate legal proceedings after the respective contract s term expiration (1-year), when the final outstanding amount of the principal debt is known. Before the litigation process Naftogaz estimates additional penalties (fines, late payment interests etc.) for non-compliance with the contractual terms, which in most cases continue to be accrued during the litigation. This approach is applied with the purpose to minimise costs and to avoid initiating a number of cases per one contract. This is also driven by the fact that under effective legislation a court claim regarding debt collection should be submitted at a debtor s place of registration. Such legislative requirement actually complicates legal work-out with the Group s debtors, which is managed out of Kyiv. In exceptional cases, upon approval of Naftogaz s management, the legal work-out in respect of the debtors is initiated before the contract s expiry date. Contract management (including conclusion of contracts, control over their execution, penalties accrued for non-compliance with contractual terms) is executed by the Gas Sales Department (discussed earlier). If a counterparty is in breach of the contractual terms, this Department prepares and transfers materials to the Legal Department in order to initiate court proceedings in respect of such a counterparty. The Economic Security Department is responsible for monitoring counterparties solvency in order to timely react in case bankruptcy procedures are initiated in respect of a debtor. Gas of Ukraine ceased its activity related to supply of the natural gas in 2011, however, is actively involved in litigation proceedings with its debtors regarding unpaid balances of principal debts and penalties including late payment interest, fines etc. 15

Section 3 Overview of receivables recovery process Starting from 2012 Naftogaz filed claims for the total amount of UAH 27,184 mln Our analysis of the court cases of the Group was mainly focused on Naftogaz and Gas of Ukraine, since these two companies were involved in sale and purchase of gas and were heavily engaged in related litigation. Although Ukrtransgas and Ukrgazvydibuvannia are also involved in litigation, this relates to gas transportation and the collection of intragroup debts and as such falls outside the terms of reference. We further split our analysis into two sections: (i) covering Gas of Ukraine from 2010 till February 2015 (see further in the report); and (ii) Naftogaz from 2012 to May 2015 (see below), i.e. starting from the year when they engaged into gas trading activities. According to legislation, Naftogaz is a guaranteed supplier of the natural gas to large industrial enterprises with the annual consumption of the natural gas over 3 mln. cm, heating companies and regional gas distribution companies. Contracts are concluded by Naftogaz for a period of one year. Hence, for each calendar year Naftogaz concludes a new set of contracts with the same customers (counterparties). As a guaranteed supplier of the natural gas Naftogaz is not permitted to refuse concluding a sale and purchase contract for a new period, even if a customer has debts for the purchase of natural gas under old contracts for prior periods. Usually, legal action is initiated after expiry of the sale and purchase contract in order to minimise the quantity of claims filed and resources of Naftogaz involved in the process of court claims. Other claims filed by Naftogaz in courts relate to its day-to-day activity (loan agreements, disputes with the state authorities, nonmaterial commercial disputes). However, their number is small compared to disputes regarding sale and purchase of natural gas. Our analysis of legal cases of Naftogaz includes legal cases, initiated from 2012 till May 2015. The total number of legal cases is 2,725. The total amount of the claims filed during the above mentioned period, including the principal debt, fines, late payment interest and inflation compensation (inflation rate and 3% per annum), is UAH 27,184 mln, including: (i) court cases with the total claims of UAH 18,953 mln, where final court decision was taken (and with respect to which UAH 14,327 mln were confirmed by the court); and (ii) court cases with the total claims of UAH 8,231 mln pending final decision of the court (see details in table on the next page). According to the Ukrainian legislation, the court is empowered to revise downward the amount of fines and late payment interest on its own discretion, taking into account the following circumstances: actual execution of the contract by a debtor, financial standing of the parties, their material and non-material interests. Also the amount of principal debt may be decreased by the court or by the parties due to its full or partial payment. Therefore, the amount of claims satisfied by the court in favour of Naftogaz may significantly differ from the amount claimed by Naftogaz. Our analysis shows that the average recovery rate for the claims where the final decision of the court was taken is 76% (calculated by dividing the amount of confirmed court claims by the claims amount where final decision was taken). This does not take into account the actual outcome from the enforcement. 18

Section 3 Overview of receivables recovery process Out of UAH 18,953 mln of claims, where the final decision of the court has been taken, Naftogaz is allowed to enforce UAH 14,327 mln According to the information provided by the Legal Department, the total claims of UAH 3,577 mln from the confirmed by the court cases were paid by debtors and UAH 5,154 mln are currently in the process of enforcement by the offices of the State Enforcement Service of Ukraine. Currently, enforcement of claims in the amount of UAH 2,491 mln is suspended mainly under legislative provisions of the Law of Ukraine On Measures Aimed At Ensuring Functioning of Enterprises of Fuel and Energy Sector No.2711-IV dated on 23 June 2005, the effect of which is expected to expire on 01 September 2015 (with the major impact on the debts due from the heating companies). In addition, UAH 27 mln shall be collected by Naftogaz under outof-court enforcement procedure based on the notary s executive inscription (in cases this is envisaged by the contractual terms with customers). This procedure does not involve application to court by Naftogaz and is not included in the total claims filed to court.

In November 2011, the license of Gas of Ukraine for sale and purchase of the natural gas was terminated. Currently, the main activity of Gas of Ukraine is collection of debts which accumulated before November 2011. Our analysis of legal cases of Gas of Ukraine includes legal cases initiated from 2010 till February 2015. The total number of legal cases analysed and relating to collection of debts for the sale of gas is 2,273. The total amount of the claims filed during the above mentioned period, including the principal debt, fines, late payment interest and inflation compensation (inflation rate and 3% per annum) is UAH 22,315 mln, including (i) court cases with claims of UAH 17,734 mln where final court decision was taken (and with respect to which UAH 13,395 mln were confirmed by the court); (ii) and court cases with the total claims of UAH 4,581 mln pending final decision of the court. Our analysis shows that the average recovery rate for the claims where final decision of the court was taken is 76% (calculated by dividing the amount of confirmed court claims by the claims amount where final decision was taken). This does not take into account the actual outcome from the enforcement. 20

Debts of Gas of Ukraine considered by courts in the amount of UAH 4,212 mln were written-off under provisions of the Law of Ukraine On Certain Issues on Debts for the Consumed Natural Gas and Electricity No.3319-VI dated 12 May 2011. In 79 court cases with the total claims of UAH 1,648 mln debts are restructured. 21

Section 3 Overview of receivables recovery process Positive court decisions with low chances to be executed are estimated at UAH 9,281 mln Case Debtors located in Crimea and ATO zone Description Debts confirmed by the court decisions in the amount of UAH 6,374 mln for Naftogaz and UAH 1,193 mln for Gas of Ukraine are due from companies registered in Crimea, Donetsk and Lugansk regions, which are not controlled by the Ukrainian Government. Currently local offices of the State Enforcement Service of Ukraine responsible for execution of the court decisions on these territories are not operating. Therefore, it is uncertain whether enforcement proceedings in these cases will result in actual recovery of debt. Debtors in bankruptcy procedure UAH 1,714 mln (Naftogaz - UAH 975 mln, Gas of Ukraine UAH 739 mln) is subject of collection from the companies which are currently in the bankruptcy procedure. Chances of collecting such debts are low, since it is unclear whether debtors will be able to pay their debts in full. Source: Information of the Legal Department of Gas of Ukraine and Naftogaz 22

Receivables are recorded in the Group s accounting records based on gas sales registers provided to the Acounting Department by the Gas Sales Department before the 15th day of the month following the month of supply. According to the standard contractual terms, acceptance acts confirming volumes of gas supplied and its price should be signed by Naftogaz and its customers by the 8 th of the month following the month of supply. Once acceptance acts are signed, they are transferred to the Accounting Department. If there are differences between the sales registers and the signed acceptance acts in terms of volume or price of gas supplied, respective adjustments are made in the Company s accounts. As discussed earlier in the report, the gas supply contracts stipulate fines and penalties for the late payments. According to management, such fines and penalties are recorded in the Group s books only if there is a respective decision of an appeal court. Until such ruling is obtained, no respective accrual is made in the Group s accounting records. 24

There is a significant dependency of debt recovery rates in respect of the heating companies debt on the amount of transfers from the state budget. Heating companies receive compensation from the state budget for the difference between the price of gas purchased for the purposes of heat production and supply to households and the price of gas included in the respective heating tariffs to households. According to the information provided by Naftogaz, in 2012 heating companies received UAH 9.8 bln of such compensation, which was eventually used to settle the debt for the gas consumed, while in 2013 no such compensation was paid to heating companies. In 2014, the compensation from the budget amounted to UAH 10.8 bln. As mentioned earlier in the report, in 2014 2015 some initiatives were introduces to improve the payment discipline of the heating companies (eg, introduction of special accounts, adoption of Law No.423 allowing Naftogaz to limit supply of gas to heating companies in case of overdue payments). While in 2011 2013 recoverability of the current debt of oblgases was rather stable (appx. 84%), in 2014 it dropped to 71%. The major factor that has negative impact on the recoverability in 2014 was increase of prices for gas, including gas purchased by oblgases for production purposes, i.e. industrial and technical losses ( ITL ). At the same time, the price of gas for ITL included in the gas distribution tariff and charged to customers in 2014 was lower compared to the actual price, resulting in oblgases inability to pay for respective gas in full. Naftogaz intends to recover full amount of debt for gas for ITL but it may prove to be challenging. 25

Total 1Q14 Heating companies Oblgases Industrial companies 2Q14 3Q14 Other clients Total 4Q14 Quarterly recovery rates were calculated on a cumulative basis as gas sales contracts are for a period of one year and payments made by customers during the year are not linked to the month of supply in the Group s accounting system. Fluctuations of quarterly recovery rates for the current debt of oblgases and heating companies reflect the seasonality of gas consumption during the year (i.e., which is increasing in cold months with respective payments being delayed and made in the following periods). In the first quarter of the year, the current debt recovery rate is the lowest, while it improves in the following quarters. For industrial companies and other clients the consumption is less dependant on the season. Improvement of recoverability of the current and old debt of heating companies in the 4 th quarter of 2014 reflects receipt by Naftogaz of the heat tariffs compensation from the state budget which related to the supply of gas in the current and previous years (UAH 10.8 bln). 26

Annexation of Crimea, ATO, increase of maximum level of gas prices in 2014 for industrial companies from UAH 3,113 per thousand cm to UAH 5,900 per thousand cm (which is also applicable to gas purchased by oblgases for ITL as well as gas consumed by heating companies to produce heat for commercial and public entities) were the major factors negatively impacting the debt repayment of the Group in 2014 (see analysis further in the report). 15% 4,226 1,012 39 600 40% 100% 15,652 9,155 4,436 1,698 2014 363 38,679 20,057 7,976 6,809 3,837 Total 60% 47% 67% 53% of the total debt was originated prior to 2014 out of the debt which originated prior to 2014 is due from heating companies of debt of industrial companies is due from companies of the chemical sector of the total debt of other customers is due from one counterparty (UAH 2,046 mln) - LLC Gazukraina-Commerce. 27

Note that there is no separate category of households entitled to subsidies (individuals identified as socially vulnerable) as prices at which gas is supplied to oblgases and heating companies are the same for all households. The subsidies are paid from the State budget to oblgases and heating companies. Given that payments for consumed gas are made by customers of oblgases through special accounts with further automatic distribution between the provider of gas (i.e., Naftogaz) and providers of transportation and distribution services (Ukrtransgas and oblgases), debt structure of oblgases accurately reflects the ultimate debtors of the Group. 28

Please note that till May 2015, payments for the gas supplied by Naftogaz to oblgases for ITL (price of which is included into the distribution tariff of oblgases) were outside the special accounts mechanism and were made at discretion of oblgases. In May 2015, changes in the respective regulations were made introducing the algorithm for such payments, but only when there was an overdue debt under gas supply contracts for the network operation purposes. In such cases, a part of the distribution tariff of oblgases which relates to cost of gas purchased for ITL is automatically distributed from special accounts of oblgases to special accounts of Naftogaz, once payments for gas and connected services (i.e. transportation and distribution) are made by the end consumers.
