Exillon Energy plc

Interim results for the first six months of 2016

25 August 2016 - Exillon Energy plc ("Exillon", the "Company" or the "Group") (EXI.LN), a London Premium listed independent oil producer with assets in two oil-rich regions of Russia, Timan-Pechora ("Exillon TP") and West Siberia ("Exillon WS"), today issues its interim results for the first six months to 30 June 2016.

Highlights

• Net profit increased by 69% to US$22.3 million (US$13.2 million in 1H 2015)

• EBITDA increased by 25% to US$38.1 million (US$30.4 million in 1H 2015)

• EBITDA per barrel increased by 39% to US$14.2 per barrel (US$10.2 per barrel in 1H 2015)

• Production decreased by 11%, with the average production for 1H 2016 equivalent to 14,807 bpd

Production

Our oil production decreased by 11% from 3.01 million to 2.69 million barrels equivalent to a decrease from 16,643 bpd to 14,807 bpd compared to 1H 2015, and 6% from 2.87 million to 2.69 million barrels equivalent to a decrease from 15,586 bpd to 14,807 bpd compared to 2H 2015.

The decrease in our production is reflecting the natural production decline curve due to the natural depletion.

We publish monthly production data, and, therefore, have already announced details of our production for the period. For reference the monthly data published during the six month period of 2016 is summarised below.

Dear Shareholders,

The first six months of 2016 were successful for Exillon. Despite the continuous volatility of oil prices, we delivered strong financial performance with significant recurring EBITDA and net profit.

Financial Position and Performance

Our EBITDA increased by 25% from US$30.4 million to US$38.1 million, with a net profit of US$22.3 million (compared to a net profit of US$13.2 million in 1H 2015). Although our revenue decreased from US$108.7 million to US$64.1 million, our netback (which we define as revenue less Mineral Extraction Tax, Export Duty and Transneft charges) rose by 15% from US$45.4 million to US$52.4 million. The decrease in our revenue was primarily a consequence of lower average oil prices during 1H 2016 as compared to 1H 2015. A decrease in our sales volumes, resulting from a decrease in production, has also contributed to the reduction in revenue.

Our EBITDA after allocation of central costs was equal to US$14.2 per barrel compared to US$10.2 per barrel in 1H 2015. The indicator was significantly enhanced, despite lower average prices achieved in 1H 2016, which led to a substantial drop in our revenue. A 39% increase of the indicator was driven mostly by the application of certain mineral extraction tax exemption by Exillon WS, which improved our netback and EBITDA.

In comparison to 2H 2015, our EBITDA per barrel decreased by 36% from US$22.3 per barrel to US$14.2 per barrel. The tax exemption mentioned above was introduced by Russian legislation in 2H 2015 with effective date from 1 January 2015. The total relevant effect attributable to 2015 was reflected in 2H 2015 results, boosting the indicator. The decline in average oil prices during 1H 2016 as compared to 2H 2015 has also contributed to the negative effect.

78% of our oil production was from Exillon WS and 22% from Exillon TP. EBITDA per barrel on an operating level (before central costs) was US$16.2 per barrel in Exillon WS (1H 2015: US$10.7 per barrel) and US$7.3 per barrel in Exillon TP (1H 2015: US$9.7 per barrel). The spread in EBITDA per barrel is growing wider between operating segments due to mineral extraction tax exemption applied by Exillon WS from 2H 2015.

Our financial position remains strong with US$126.7 million of cash and cash equivalents as at 30 June 2016. A term loan of US$100.0 million taken out in March 2012 is the Company's only debt. As at 30 June 2016, the outstanding debt had reduced to US$23.1 million, as a result of scheduled repayments of principal. Our net cash position was US$103.6 million.

As of 24 August 2016 our cash and cash equivalents had decreased to US$107.8 million resulting in a net cash position of US$84.5 million.

Capital expenditure during the period was US$4.8 million (1H 2015: US$29.1 million), 16% of which was incurred in Exillon TP and 84% in Exillon WS (1H 2015: 7% in Exillon TP, 57% in Exillon WS and 36% in corporate companies that are managed at the Group level). Of this total, US$2.0 million was attributable to drilling, US$2.7 million to infrastructure and US$0.1 million to seismic data acquisition and interpretation (1H 2015: US$4.0 million was attributable to drilling, US$13.2 million to infrastructure and US$1.3 million to seismic data acquisition and interpretation). During 1H 2015 capital expenditure related to the corporate companies was attributable to the purchase of an aircraft, which was subsequently leased to an unrelated third party for a period of ten years.

Drilling Update

During the period we drilled three production oil wells. The drilling was carried out only at Exillon WS and the drilling results were successful for all wells.

FINANCIAL REVIEW

The interim condensed consolidated financial information of Exillon Energy plc for the six month period ended 30 June 2016 has been prepared in accordance with IAS 34 "Interim Financial Statements". The condensed consolidated financial information and the relevant notes should be read in conjunction with this review which has been included to assist in the understanding of the Group's financial position at 30 June 2016 and financial performance for the six months then ended.

Revenue

Our revenue for the six months ended 30 June 2016 decreased by 41% compared to the same period in 2015, reaching US$64.1 million (1H 2015: US$108.7 million), of which US$14.1 million or 22% came from export sales of crude oil and US$50.0 million or 78% came from domestic sales of crude oil (1H 2015: US$50.1 million or 46% came from export sales of crude oil and US$58.6 million or 54% came from domestic sales of crude oil). This change in revenue is attributable to:

· a decrease in production leading to a 10% decrease in sale volumes from 2,972,066 bbl in 1H 2015 to 2,683,413 bbl in 1H 2016; and

· a decline in average commodity prices: we achieved an average oil price of US$28.9 / bbl for export sales (1H 2015: US$50.1 / bbl) and US$22.8 / bbl for domestic sales (1H 2015: US$29.7 / bbl).

Although the achieved average price for export sales significantly exceeds average domestic sales price, the effect is diminished by the expenses associated with export sales, such as export duty and transportation services provided by Transneft.

Operating Results

Cost of sales excluding depreciation and depletion expenses decreased to US$16.6 million (1H 2015: US$54.2 million), along with the decrease in production by 11% to 2,694,875 bbl (1H 2015: 3,012,458 bbl). The difference between the production volumes and sales volumes is due to the change in the oil inventory balance during the period. The major decrease occurred in mineral extraction tax from US$45.0 million in 1H 2015 to US$7.1 million in 1H 2016. It is mostly a result of 0% mineral extraction tax rate applied to the oil produced from a certain oil reservoir by Exillon WS, which includes oil production from the majority of oil wells located at EWS I and EWS II oil fields. A 0% tax rate was applied to 1,766,814 bbl or 84% of crude oil produced by Exillon WS out of the total production of 2,102,145 bbl during the first six months of 2016. The tax exemption for this oil reservoir was introduced by Russian legislation in the second half of 2015 with effective date from 1 January 2015. In general, the increase of the base tax rate from 766 Russian Roubles per tonne of crude oil in 2015 to 857 Russian Roubles per tonne in 2016 was offset by the combined effect of Russian Rouble depreciation, decline in average crude oil prices used in the calculation of the tax and the decrease in production volumes. In 1H 2016 the effective average exchange rate was 70.2583 Russian Roubles to one US dollar (Rouble/US$) compared to 57.3968 Rouble/US$ in 1H 2015.

Depreciation and depletion costs ("DD&A") primarily relate to the depreciation of proved and probable reserves and other production and non-production assets. These costs amounted to US$8.9 million in 1H 2016 compared to US$10.4 million in 1H 2015. The decrease in DD&A costs was a result of the combined effect of lower production volumes and Russian Rouble depreciation, since most of DD&A costs are nominated in Russian Roubles, partially offset by DD&A charge on the additions to property, plant and equipment.

Selling expenses in 1H 2016 amounted to US$7.5 million (1H 2015: US$20.3 million) and comprised of export duties of US$3.0 million, transportation services of US$3.7 million and services of the Transneft crude oil metering system of US$0.8 million (1H 2015: export duties of US$14.7 million, transportation services of US$5.4 million and other selling expenses of US$0.2 million). The major decrease related to export duty as a result of reduced export sales in our sales mix and a decline in average crude oil prices used in the calculation of the duty. Transportation services included services provided by Transneft and trucking services from the infield oil filling stations to oil terminals at Transneft. Services provided by Transneft of US$1.6 million (1H 2015: US$3.8 million) related to export sales of crude oil and decreased due to the change in our sales mix. During both periods domestic customers have been paying directly to Transneft for its transportation services. In 2016, all crude oil produced at Exillon TP was trucked to Transneft pipeline, due to changes in transportation logistics affecting new customers. This drove an increase in trucking services to Transneft from US$1.6 million in 1H 2015 to US$2.1 million in 1H 2016. Accordingly, in 2016 Exillon TP used Transneft crude oil metering system services at a cost of US$0.8 million. These changes at Exillon TP were in place starting from the second half of 2015.

Administrative expenses in 1H 2016 (excluding depreciation and amortization) amounted to US$2.8 million in comparison to US$4.2 million in 1H 2015. In 1H 2016, savings were achieved in salary and related taxes and consulting services.

In 1H 2016 interest income amounted to US$0.8 million (1H 2015: US$1.4 million) resulting from surplus cash being held on short-term bank deposits and purchase of short-term interest-bearing bank bills of exchange. The decrease in Russian Rouble nominated interest income was a result of depreciation of Russian Rouble against US dollar during 1H 2016 as compared to 1H 2015.

It should be noted that in accordance with IFRS a foreign exchange loss of US$2.1 million (1H 2015: US$4.2 million) has been included in our net profit arising from the revaluation of foreign currency monetary items (cash and cash equivalents, accounts receivable and payable, other assets) using the closing rate at the reporting date. The foreign exchange loss in 1H 2015 was mostly attributable to US dollar nominated cash and cash equivalents held by Russian subsidiaries and was a consequence of the exchange rate decrease from 56.2584 Rouble/US$ as of 31 December 2014 to 55.524 Rouble/US$ as of 30 June 2015. The foreign exchange loss recognised in 1H 2016 was a result of the exchange rate decrease from 72.8827 Rouble/US$ as of 31 December 2015 to 64.2575 Rouble/US$ as of 30 June 2016. During 1H 2016 the foreign exchange loss arising on US dollar denominated cash held by Russian subsidiaries was offset by foreign exchange gain attributable to the intercompany loan, which is expected to be settled to fund repayments of the Group's external debt and is not considered to be as permanent as equity. During both periods the exchange rate endured a substantial volatility: in 1H 2015 it fluctuated between the highest rate of 69.664 Rouble/US$ achieved on 3 February 2015 and the lowest rate of 49.1777 Rouble/US$ achieved on 20 May 2015; while in 1H 2016 the highest rate of 83.5913 Rouble/US$ was achieved on 22 January 2016 and the lowest rate of 63.7162 Rouble/US$ was achieved on 23 June 2016. A foreign exchange gain of US$41.2 million (1H 2015: US$4.4 million) has been recognised in other comprehensive income as part of the translation reserve.

As a result of the above, net profit for the first six months of 2016, which includes depreciation costs and foreign exchange translation effects, amounted to US$22.3 million compared to net profit of US$13.2 million for the six months ended 30 June 2015.

Financial position

We ended the period with US$126.7 million of cash and cash equivalents and outstanding borrowings of US$23.1 million (31 December 2015: US$64.6 million and US$38.6 million, respectively). The entire outstanding borrowings relate to the current portion of the loan principal. According to the repayment schedule it will be repaid within 12 months after the reporting date in equal quarterly instalments. During the six months ended 30 June 2016 the principal of US$15.4 million has been repaid in compliance with the repayment schedule.

The additions to the property, plant and equipment of US$5.4 million included US$0.6 million of capitalised interest, with the remaining amount attributable to the drilling of oil wells and further development of infield infrastructure in Exillon WS and Exillon TP. This was partially offset by depreciation and depletion of US$8.9 million, while the positive effect was enhanced by the translation difference of US$37.9 million, due to the appreciation of the Russian Rouble against the US dollar at the reporting date (the exchange rate was 72.8827 Rouble/US$ as of 31 December 2015 and 64.2575 Rouble/US$ as of 30 June 2016).

Cash flow

In 1H 2016 operating cash flows reflect a cash reimbursement of $26,847 thousand received in April 2016 by Exillon WS for mineral extraction tax, which was receivable as of 31 December 2015 due to the tax exemption applied in 2015.

Principal risks and uncertainties

The principal risks and uncertainties affecting the business activities of the Group are set out on pages 20 to 23 of the Directors' Report section of the Annual Report for the year ended 31 December 2015, a copy of which is available on the Company's website at www.exillonenergy.com.

INDEPENDENT REVIEW REPORT TO Exillon Energy PLC

Introduction

We have been engaged by the Exillon Energy PLC (the "Company") to review the condensed consolidated set of financial statements in the half-yearly financial report for the six months ended 30 June 2016 which comprises the interim consolidated statement of comprehensive income, interim consolidated statement of financial position, interim consolidated statement of changes in equity, interim consolidated statement of cash flows and the related notes 1 to 22. We have read the other information contained in the half-yearly financial report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed consolidated set of financial statements.

This report is made solely to the Company in accordance with guidance contained in International Standard on Review Engagements 2410 (UK and Ireland) "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company, for our work, for this report, or for the conclusions we have formed.

Directors' Responsibilities

The half-yearly financial report is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the half-yearly financial report in accordance with the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

As disclosed in note 2, the annual consolidated financial statements of the Company are prepared in accordance with International Financial Reporting Standards. The condensed consolidated set of financial statements included in this half-yearly financial report has been prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting".

Our Responsibility

Our responsibility is to express to the Company a conclusion on the interim condensed consolidated set of financial statements in the half-yearly financial report based on our review.

Scope of Review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410, "Review of Interim Financial Information Performed by the Independent Auditor of the Entity" issued by the Auditing Practices Board for use in the United Kingdom. A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK and Ireland) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half-yearly financial report for the six months ended 30 June 2016 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

Total interest paid during the six months ended 30 June 2016 comprised $1,286 thousand (the six months ended 30 June 2015: $2,176 thousand).

notes to INTERIM condensed consolidated financial statements (UNAUDITED)

1. Background

The principal activity of Exillon Energy plc (the "Company" or the "Parent") and its subsidiaries (together "the Group") is exploration, development and production of oil. The Group's production facilities are based in the Republic of Komi and the Khanty-Mansiysk Region of the Russian Federation. The Group's structure is provided in Note 22.

Exillon Energy plc is a public limited company which is listed on the London Stock Exchange and is incorporated and domiciled in the Isle of Man. The Company was formed on 27 March 2008. Its registered address is Fort Anne, South Quay, Douglas, Isle of Man, IM1 5PD.

As at 30 June 2016, the largest shareholder has 29.99% (2015: 29.99%) in the Company's outstanding issued share capital.

The Group's operations are conducted primarily through its operating segments, Exillon TP and Exillon WS.

2. basis of preparation

This condensed consolidated interim financial information for the six months ended 30 June 2016 has been prepared in accordance with International Accounting Standard ("IAS") 34, "Interim financial reporting". The condensed consolidated interim financial information should be read in conjunction with the annual financial statements for the year ended 31 December 2015, which have been prepared in accordance with International Financial Reporting Standards ("IFRSs"). The operations carried out by the Group are not subject to seasonality or cyclical factors.

3. going concern

The principal risks and uncertainties, which are likely to affect the Group's future development, performance and position including financial risk factors are set out in paragraph "Principal risks and uncertainties" above. The Group's forecasts and projections, taking account of reasonable changes in trading performance (including oil price), show that the Group can operate with its current cash holding. The assessment was performed with consideration of Group's business, budget, cash flow forecast, trading estimates, contractual arrangements, committed financing and exposure to contingent liabilities, financial covenant calculation and the principal risks and uncertainties.

Having considered the above matters, the Directors have a reasonable expectation that the Group has adequate resources to continue operational existence and meet its liabilities as they fall due for the foreseeable future, being at least 12 months from the date of approval of the consolidated interim financial statements. For this reason the Directors continue to adopt the going concern basis of accounting in preparing the consolidated interim financial statements.

4. ACCOUNTING POLICIES

Accounting policies - the accounting policies applied are consistent with those of the annual consolidated financial statements for the year ended 31 December 2015.

During the six months ended 30 June 2016 the Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

Critical accounting judgments and key sources of estimation uncertainty:

The preparation of interim financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expense. Actual results may differ from these estimates.

In preparing these condensed consolidated interim financial statements, the significant judgements made by management in applying the Group's accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements for the year ended 31 December 2015, except for the change in certain major assumptions used in estimation of decommissioning costs:

Decommissioning costs

Provision for decommissioning represents the present value of decommissioning costs relating to the Russian Federation oil and gas interests, which are expected to be incurred in a time period between 2025 and 2038. These provisions have been created based on the Group's internal estimates. Assumptions, based on the current economic environment, have been made which management believe are a reasonable basis upon which to estimate the future liability. Those estimates are reviewed regularly to take into account any material changes to the assumptions. However, actual decommissioning costs will ultimately depend upon future market prices for the necessary decommissioning works required which will reflect market conditions at the relevant time. Furthermore, the timing of decommissioning is likely to depend on when the fields cease to produce at economically viable rates. This in turn will depend upon future oil and gas prices, which are inherently uncertain.

Major assumptions used in estimation of decommissioning costs are set out below:

Exillon TP:

· as at 30 June 2016, undiscounted value of estimated future cash outflows is estimated at $5,744 thousand (31 December 2015: $5,007 thousand);

· expected timing of future cash outflows - the majority of the expenditure is expected to take place in a range between 2026 and 2038 (2015: between 2026 and 2038);

· discount rate (based on long-term maturity Russian government bonds) - 8% per annum (2015: 9%);

· inflation rate (based on the external analysts' forecasts) - 4-8% per annum (2015: 4-8%).

If the discount rate had increased by 1% to 9% at 30 June 2016, the decommissioning liability would have been $417 thousand lower (31 December 2015: $306 thousand lower).

Exillon WS:

· as at 30 June 2016, undiscounted value of estimated future cash outflows is estimated at $10,349 thousand (31 December 2015: $8,978 thousand);

· expected timing of future cash outflows - the majority of the expenditure is expected to take place in 2025 (2015: 2025);

· discount rate (based on long-term maturity Russian government bonds) - 8% per annum (2015: 9%);

· inflation rate (based on the external analysts' forecasts) - 4-8% per annum (2015: 4-8%).

If the discount rate had increased by 1% to 9% at 30 June 2016, the decommissioning liability would have been $593 thousand lower (31 December 2015: $506 thousand lower).

Estimation of oil and gas reserves

Oil and gas reserves are key elements in the Group's investment decision-making process. They are also an important element in testing for impairment. Changes in oil and gas reserves, particularly proved and probable reserves, will affect unit-of-production depreciation charges in the consolidated statement of comprehensive income.

Proved oil and gas reserves are the estimated quantities of crude oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e. prices and costs as of the date the estimate is made. Probable reserves are those additional reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than proved reserves but more certain to be recovered than possible reserves. Estimates of oil and gas reserves are inherently imprecise, require the application of judgement and are subject to future revision. Accordingly, financial and accounting measures (such as depletion charges and provision for decommissioning) that are based on proved and probable reserves are also subject to change.

Proved reserves are estimated by reference to available reservoir and well information. All proved reserves estimates are subject to revision, either upward or downward, based on new information, such as from development drilling and production activities or from changes in economic factors, including product prices, contract terms or development plans. In general, changes in the technical maturity of hydrocarbon reserves resulting from new information becoming available from development and production activities have tended to be the most significant cause of annual revisions.

In general, estimates of reserves for undeveloped or partially developed fields are subject to greater uncertainty over their future life than estimates of reserves for fields that are substantially developed and being depleted. As a field goes into production, the amount of proved reserves will be subject to future revision once additional information becomes available through, for example, the drilling of additional wells or the observation of long-term reservoir performance under producing conditions. As those fields are further developed, new information may lead to revisions.

Changes to the Group's estimates of proved and probable reserves also affect the amount of depletion recorded in the Group's consolidated financial statements for property, plant and equipment related to oil and gas production activities. A reduction in proved and probable reserves will increase depletion charges (assuming constant production) and reduce profit.

Proved and probable reserve estimates of the Group as of 31 December 2014 were based on the reports prepared by Miller and Lents Ltd, independent engineering consultants, adjusted by 2015 and the six months ended 30 June 2016 production.

As at 30 June 2016, the net carrying amount of oil and gas properties and related cost of production licence was $286,184 thousand (31 December 2015: $253,675 thousand).

Taxation

The Group is subject to income tax and other taxes. Significant judgment is required in determining the provision for income tax and other taxes due to the complexity of the tax legislation incorporated in the Russian Federation. There are many transactions and calculations for which the ultimate tax determination is uncertain. The Group recognises liabilities for anticipated tax audit matters based on estimates on whether additional tax will be due. Where the final tax outcome is different from the amounts that were initially recorded, such differences will impact the amount of tax and tax provisions in the period in which such determination is made. Deferred tax assets are recognised for all unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilised. Significant management judgment is required to determine the amount of deferred tax assets that can be recognised, based upon the likely timing and the level of future taxable profits together with future tax planning strategies.

Net investment in foreign operations

Loans issued to foreign subsidiaries, the settlement of which is neither planned nor likely to occur in the foreseeable future, form part of the Group's net investment in those subsidiaries. In 2014 the Group transferred $43.0 million from Exillon Finance LLC to Kayumneft JSC through an intercompany loan. The Group did not consider that repayment of this intercompany loan was likely to occur in the foreseeable future. The intercompany loan formed a part of the Group's net investment in Kayumneft JSC. Foreign exchange differences on the intercompany loan and the corresponding tax effect were recognised in other comprehensive income.

In light of continued decline in oil prices and significant weakening of Russian Rouble leading to the decrease in the Group's profits, in June 2015 management reassessed the judgement and determined that this intercompany loan was expected to be settled to fund repayments of the Group's external debt. Accordingly, from that date, a foreign exchange loss of $11,899 thousand on the intercompany loan has been recognized in profit or loss in 2015. Of this total, a foreign exchange loss of $773 thousand was recognised in the first half of 2015. During the six months ended 30 June 2016, a foreign exchange gain of $4,046 thousand on the intercompany loan has been recognized in profit or loss.

Impairment

The carrying value of the Group's assets can be significantly affected by change in oil prices. The drastic drop in oil price during the last quarter of 2014 and its continuous volatility thereafter have indicated potential impairment of oil and gas properties. The detailed impairment review analysis was made as of 31 December 2015. For the assessment purposes oil and gas assets were grouped into cash-generating units (being Group's oil fields), while other property, plant and equipment assets were allocated to oil fields according to their reserve share in the total portfolio. The recoverable amount for each cash-generating unit was determined based on the future cash flows to be obtained from the proved and probable reserves of the relevant oil field discounted to their present value. The projection of cash flows was made for the period covering 2034, being the expected period to extract currently estimated reserves. With reference to the performed analysis management was able to conclude that in each cash-generating unit the recoverable amount (based on fair value less costs of disposal) exceeds carrying amount of assets, and therefore there is no impairment to be recognised as of 30 June 2016 (31 December 2015: nil).

Key assumptions used for the impairment review as at 31 December 2015 are set out below:

· exchange rate: 72.8827 Russian Roubles per 1 US dollar (actual rate as of 31 December 2015);

· oil price: $18.6 / bbl for domestic sales and $27.3 / bbl for export sales in 2016. The assumption for 2016 was made with the reference to actually achieved prices during the first quarter 2016; growth rate of 10% (nominal) was applied to oil price in 2017, 2018 and 2019, which is in-line with the recent market forecasts. Growth rate conservatively estimated at nil after the end of the four year forecast, due to the current increased uncertainty in future oil price movements. Oil price after 2019: $24.8 / bbl for domestic sales and $36.3 / bbl for export sales;

· discount rate: 10% per annum (post-tax).

Management believes that no reasonably possible change in any of the above key assumptions would cause the recoverable amount to be below the carrying value of any cash-generating unit.

5. OPERATING SEGMENTS

Management has determined the operating segments based on the reports reviewed by Directors that make the strategic decisions for the Company, who are deemed to be the chief operating decision maker (CODM).

Exillon Energy plc manages its business through two operating segments, Exillon TP and Exillon WS.

· Exillon TP: upstream business based in the Timan-Pechora basin in the Komi Republic in the Russian Federation. The revenue is derived from extraction and sale of crude oil.

· Exillon WS: upstream business based in Western Siberia in the Russian Federation. The revenue is derived from extraction and sale of crude oil.

No operating segments have been aggregated to form the above reportable operating segments.

Segmental information for the Group for the six months ended 30 June 2016 is presented below:

Segmental information for the Group for the six months ended 30 June 2015 is presented below:

The selling prices between operating segments are on an arm's length basis in a manner similar to transactions with third parties. There were no intersegment revenues during the six months ended 30 June 2015 and 2016.

Unallocated category represents costs of corporate companies that are managed at the Group level.

Management assesses performance of the operating segments based on EBITDA which is calculated as follows: operating result plus depletion and depreciation, plus/minus foreign exchange gains/(losses) and plus/minus other significant one-off income/(expenses).

Net back is defined as revenue less direct and indirect government taxation. The indicator is calculated as revenue less Mineral Extraction Tax, Export Duty and Transneft transportation services.

6. revenue

7. cost of sales

During the six months ended 30 June 2016, Exillon WS applied 0% mineral extraction tax rate to the oil produced from the certain oil reservoir, which include oil production from the majority of oil wells located at EWS I and EWS II oil fields. The tax exemption for this oil reservoir was introduced in the second part of 2015 (with effective date from 1 January 2015). The tax exemption amounted to $16,695 thousand for the first six months of 2016.

During the six months ended 30 June 2016, Exillon TP applied reducing factors to the mineral extraction tax rate, which reflect the specific characteristics of oil production from ETP V and ETP VI oil fields. The tax exemption amounted to $418 thousand for the first six months of 2016.

8. selling expenses

9. administrative expenses

10. earnings per share

Basic earnings per share ("EPS") is calculated by dividing net profit for the period attributable to ordinary equity shareholders of the Company by the weighted average number of ordinary shares outstanding during the period.

The following reflects the income and adjusted share data used in the EPS computations:

11. Property, plant and equipment

Decommissioning costs of $6,938 thousand and $5,608 thousand were included within oil and gas properties as of 30 June 2016 and 31 December 2015, respectively. Change in estimates relates to the change in the assumptions used in estimation of decommissioning costs (Note 4).

Cumulative capitalized borrowing costs of $19,826 thousand and $19,267 thousand were included within oil and gas properties as of 30 June 2016 and 31 December 2015, respectively. Total borrowing costs incurred during the six months ended 30 June 2016 period amounted to $1,108 thousand, of which $559 thousand were capitalised (31 December 2015: total borrowing costs amounted to $3,590 thousand of which $1,787 thousand were capitalised). There is no tax relief related to the capitalised borrowing costs.

Exploration and evaluation assets as of 30 June 2016 and 31 December 2015 comprise the ETP VII licence acquired in December 2011. Construction in progress relates to the construction of infield infrastructure and drilling of oil wells commenced in 2015 and 2016.

In 2015, the Group purchased an aircraft for $10,600 thousand, which was subsequently leased to an unrelated third party for a period of ten years at a monthly lease payment of $130 thousand; with the retained right to use the aircraft for the Company's needs on commercial payment terms.

Minimum lease payments were as follows:

12. Inventories

Inventories included no obsolete or slow-moving items as of 30 June 2016 (31 December 2015: nil).

13. trade and other receivables

Trade receivables are non-interest bearing. In determining the recoverability of a trade receivable, the Group considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the reporting date. Accordingly, the management of the Group believes that there is no further credit provision required in excess of the allowance for doubtful debts.

At 31 December 2015, taxes recoverable included $31,390 thousand of mineral extraction tax for crude oil, which was receivable due to the tax exemptions applied to the oil produced from the certain Group's oil fields (Note 7). In April 2016, Exillon WS received a cash reimbursement in the amount of $26,847 thousand. The remaining amount of $4,543 thousand has been offset against taxes payable (of which $3,751 thousand offset against income tax and $792 thousand against VAT).

14. other assets

15. provision for decommissioning

In accordance with the licence agreements the Group is liable for site restoration, clean up and abandonment of the wells upon completion of their production cycle. The provision for future site restoration relates to obligations to restore the oilfields after use. All of these costs are expected to be incurred at the end of the life of wells between 2025 and 2038 (Note 4). They depend on the estimated lives of the wells, the scale of any possible contamination and the timing and extent of corrective actions.

The unwinding of the discount related to future site restoration and abandonment reserve is included within finance costs.

16. trade and other payables

Trade and other payables are non-interest bearing. At 30 June 2016, advances of $11,226 thousand (31 December 2015: $6,825 thousand) relate to the receipts from customers for the sales in July 2016 (31 December 2015: January 2016).

17. borrowings

There is no material difference between the carrying amount and fair value of borrowings.

Credit Suisse - On 10 September 2010, the Group agreed a loan facility of $50 million with a term of 3.5 years. Interest was charged at LIBOR plus 7%.

In March 2012 the existing loan facility was replaced by a $100 million loan facility with a term of 5 years. The loan bears an interest rate at LIBOR plus 6% and is repayable in equal quarterly installments with the first repayment made in March 2014. The interest is payable quarterly with the first payment made in June 2012.
