Directors’ report Directors of Partex Holding B.V. (the “Company” or Partex) hereby present its financial statements for the financial year ended on 31st December 2017.

General information The Company is a 100% subsidiary of the Foundation, a Portuguese private institution of public utility. Its statutory aims are in the fields of arts, charity, education and science. The Company’s business is the production of oil and gas and operates in this market since 1938, well known as the Partex Oil and Gas Group. With its expertise and technical skills the company is a valued partner for major oil companies in different sized operations. The Partex Oil and Gas Group is organized primarily by geographical areas and holds interests in concessions and joint ventures engaged in upstream activities related to the oil and gas industry namely, exploration, development, production and sales. The group has a long tradition of participating in oil and gas concessions and joint ventures in the Middle East and in most recent years became an operator in oil upstream activities in other parts of the World. The Group was the operator for the initial phase of the Dunga field in and is presently the operator of two fields in the Northeast of . Oil Exploration activities by the Group are currently in Angola, whereas exploration activities in Brazil and have ceased. During 2016 the company’s transfer of the holding company to the Netherlands was fully completed. In addition to this, the Group’s subsidiary PMO Services S.A., based in Vaduz, Liechtenstein, was closed and the formal liquidation of this subsidiary will be executed in the first half of 2018. The Group is structured in sub-holding companies, management units, concession companies and service companies that provide all the necessary advice and financial, technical, management and human resources support to the joint ventures and operating companies in which the Group participates. All activities are carried out in accordance with the strategy and guidelines defined by the Company.

Financial information • The revenue for the year increased USD 69 million to USD 322 million. Main driver behind this revenue increase relates to the increase in average sales price of approximately USD 10, compared with prior year. Production levels remained stable compared to prior year, whereas a decrease in the production levels of the concession in the Sultanate of (due to OPEC production measures), was compensated by an increased production from the Group’s concession in Kazakhstan. The profit for the year is approximately USD 7 million less than prior year, however in prior year the company recorded an impairment reversal gain of USD 60 million approximately, which in current year is less than USD 1 million. This shows an increase in underlying profit (excluding impairment losses / reversal) of the Group of almost USD 53 million. • The increased underlying profit also positively affected the cash position of the Group. Despite a dividend payment of EUR 30 million, which was declared by the end of 2016 to

Consolidated IFRS FS 2017 FINAL 1 Partex Holding B.V.

the shareholder, the cash position of the Group increased USD 11.4 million to USD 74.7 million by the end of 2017. • Dividends from our participation in OLNG were USD 12.5 million and in line with prior year. However, during 2017 the company recorded a (non-cash) adjustment of USD 5.4 million to align the accounting policies of the investment with the Group accounting policies as described by IFRS (IAS 28). • An increase of USD 26 million in deferred tax liability (2016: USD 22 million), solely relating to the Kazakhstan operations, also had a significant negative impact on the results of the Group. • The negotiations between the current partners and Government of Kazakhstan continues regarding a contract extension for another 15 years of the Dunga concession. Earlier in 2018, the Minister of Energy confirmed its interest in continuing to work closely with the Contractor on the matters included in the MoU dated September 2014. This extension should be formally signed after a new law (RoK Code dated 27 December 2017 No 125-VI on Subsurface and Subsurface use taking into account the provisions regarding extension of the contract duration) comes into force in Kazakhstan in June 2018. With the extension until 2039, the alternative development plan which was submitted in October 2016, foresees the full recoverability of the cost pool and a significant increase in the project economics.

Significant risks and uncertainties Risk management is considered a continuous process within the Group and the underlying risk management framework adheres to the requirements set by Group management in this matter. Considering the Industry of the Group and underlying market circumstances, the Group is mainly exposed to the risks coming from the current volatility of oil prices. Management is actively managing these risks and sets the boundaries and maximum level of risk acceptable for the Group. The (development of) significant risks facing the Group are discussed periodically within the Management meetings and adequately actioned upon. In this matter, the risk appetite of Management can be considered conservative as the current exposure from ongoing exploration activities within new oil field is balanced with a regular return from the current long-term oil investments. A breakdown of the risk per category is noted below: • Strategy While being strongly committed to the successful development of those ventures, Partex is actively engaged in the process of identifying new investment opportunities in the oil and gas business. It is the Company’s culture to preserve and further develop the historic partnerships in the Middle East where Partex will continue placing its human and technological resources in support of the continued development of the oil and gas industry. • Operational Despite the stable growth of the oil price, management of the Group will continue to closely monitor the cost of the Group and optimizing the administration structure of the Group. Equally the influence of Partex in operating companies will be used to optimize and improve the operational activities in the companies where the Group is a stakeholder. • Financial It’s the company’s goal to remain financially independent and maintain the ability to pay dividends to its sole shareholder.

Consolidated IFRS FS 2017 FINAL 2 Partex Holding B.V.

• Financial reporting The solid and reliable financial reporting will be continued and adopted to new requirements, whenever needed. • Laws and regulations The entire Partex Group is adhering to existing laws and regulations. Whenever inconsistencies will be discovered Management will take all necessary steps and set corrective measures.

Financial and non-financial performance indicators Looking at the oil and gas industry in general the oil price development is a major factor for the success or non-success for current developed and new exploration projects. The expected oil price path has its effect on the impairment (loss) or reversal (gain) on the joint venture assets of the company. The investment in the Middle East have matured and the Group expects to benefit from a further increase in the oil price through these investments, as well as in the investment in Kazakhstan. As noted above as well as in note 12 to the financial statements, the current fair value of the joint venture assets in Kazakhstan is mostly sustained by the expected residual value proceed of fixed assets at the end of the concession. Therefore, there is an inherent uncertainty in this amount, as the proceeds are partly dependant on agreement with the local Government. However, following the current negotiations with the partners to the concession and local government, management expects that the current value of the assets will be recovered through extension of the concession. As also noted in note 11 to the financial statements, the company is also awaiting the outcome of ongoing discussions in Angola between the consortium and local government on possible changes to the fiscal regime. Further optimisation of the fiscal regime is considered crucial for the recoverability of the current capitalised exploration costs. Based on the ongoing discussions with the local Government, management of the Group is positive on the outcome and change to the fiscal regime.

Environmental and personnel related information The Company has a no-harm to people and environment policy. In fields operated by Partex the best oil field practices are applied. Management makes sure with permanent staff training that state-of-the-art technologies and safety rules are being applied and observed. The number of average full time employees decreased to 83 in 2017 from 99 in 2016.

Information regarding financial instruments The group operates in an industry which is traditionally considered to be risky compared to other economic areas. The group is managed so as to obtain a reasonable balance between risk and expected reward. • Operational risk: The Partex Group is an active oil and gas exploration company and therefore runs the risk that its exploration activity may be unsuccessful. • Market risk: The Group sells most of its production on annual sales contracts thus reducing its short term exposure to price fluctuations.

Consolidated IFRS FS 2017 FINAL 3 Partex Holding B.V.

• Credit risk: Credit risk is that a customer or counterparty fails to perform or to pay amounts due causing financial loss to the group. The Group carefully assesses the quality of its counterparties when entering into business relationships with them. • Liquidity risk: Liquidity risk is the risk that suitable sources of funding for group business activities may not be available. The Group believes that it has access to sufficient sources of funding to meet current commitments.

Research and development information As part of its effort to ensure adequate technical support to operations and competitive advantage, Partex undertakes several R&D programmes aimed at the development of specific knowledge and technologies in critical areas of the industry. These programmes are supported and further developed through contacts, partnerships and protocols which the Group has established with technical entities of recognised quality, such as leading technological centres, research institutes and universities. Areas that have been addressed include seismic, reservoir characterization, compositional simulation, fluid characterisation, geo–statistical modelling, geo-mechanics and facilities projects.

Other information

• The Company uses standard IT systems for administration and financial reporting. These systems are kept up-to-date and the persons using them are properly trained to professionally use them. • Partex is seeking long term relationship with its clients. The Group is present at major events in the oil and gas industry and maintains good working relationships with other international oil companies and oil producing countries for being recognized as reliable partners for ongoing and future oil projects. • New and innovative ideas are supported from Group Management. • Financial development and financing is continuously monitored from finance department and Group Management.

Information concerning application of code of conduct

An important cornerstone in the day to day operation and management of activities is the timeous identification and management of Health, Safety and Environmental (HSE) issues. HSE and Social Responsibility principles and philosophies are set out in the HSE & SR policy statement, which has been formulated to ensure that the Company’s intentions are clear to all stakeholders.

Information on male/female partitioning of board members The target figures of at least 30% of the natural members of the Board of Directors and the Supervisory Board being female could not be achieved by the Group given the size of the

Consolidated IFRS FS 2017 FINAL 4 Partex Holding B.V.

Company and number of Board members, despite the current chairman of the Supervisory Board being a female. Partex aims to achieve the quota but given that the oil industry is pre-dominantly a male industry it will remain for the foreseeable future a challenge to find appropriate female candidates.

Future developments • Investments Partex is open for new investments and projects whenever interesting projects are offered or identified. • Financing Partex aims at funding its activities from its own cash flows but is open to alternatives if reasonable or needed. • Human resources The Group aims to be an attractive employer by offering its employees to grow and develop within the organization. Partex makes sure that employees are properly trained and equipped with the necessary skills to perform their work in an appropriate manner. For the near future no significant changes in the employee base is expected. • Research and development The company performs for each of the projects intense research and development opportunities activities in what concerns an optimized approach to explore oil or gas reservoirs. In addition, the company is ready to develop, apply and test new ideas, methods and processes that help to improve the quality, reliability, performance and/or safety. • Circumstances on which the development of the turnover and profitability depends. Being a company that is acting in the oil and gas industry the exposure to oil prices and the global demand for hydrocarbons are major external drivers for the development of the company. Furthermore, Partex is also depending on external factors (price) and global developments which are beyond the control of Group Management. Nevertheless, the current developments in the Industry showing increased demand due to increased economic activity, including the increasing oil price, are setting a positive tone for the coming future of the Group.

Notes to the consolidated financial statements for the year ended 31 December 2017

1 Reporting entity Partex Holding B.V. (the ‘Company’) is a limited liability Company domiciled in Amsterdam, The Netherlands. The Company’s registered office is Claude Debussylaan 10, 1082 MD Amsterdam, the Netherlands and its registration number is 58329129. The Company is a wholly owned subsidiary of the Fundaçao Calouste Gulbenkian, a charitable foundation established under the laws of Portugal. The Company was set up in July 2013 as ultimate holding company of the Group which holds investments in the oil and gas industry. The subsidiaries of the Group are active in the oil and gas industry from participating in exploration and development of oil and gas concessions to upstream activities. These consolidated financial statements comprise the Company and its subsidiaries (collectively the ‘Group’ and individually ‘Group companies’).

2 Basis of preparation

(a) Statement of compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as adopted by the European Union (EU-IFRSs). The consolidated financial statements were authorised for issue by the Board of Directors on 17 April 2018.

(b) Basis of preparation The consolidated financial statements have been prepared on the historical cost basis except for the below items: • Pension scheme investments, which are accounted for at fair value in accordance with IAS 19. • Assets available for sale, which are accounted for at fair value through OCI as per IAS 39. These financial assets were sold during 2017. The accounting policies applied by the Group in the preparation of these consolidated financial statements for the year ended 31 December 2017 are consistent with the ones used in the preparation of the Group’s financial statement as at 31 December 2016.

(c) Going concern The financial statements have been prepared under the going concern assumption. In assessing all available financial- and market information, as well as existing and available hydrocarbon reserves in combination with already existing business- and investment plans there are no reasons or indications for Management to assume that an economically successful continuation of the business could not be possible.

Consolidated IFRS FS 2017 FINAL 13 Partex Holding B.V.

(d) Functional and presentation currency These consolidated financial statements are presented in USD, which is the Group’s functional currency. For each entity, the Group determines the functional currency and items included in the financial statements of each entity are measured using that functional currency. The Group uses the direct method of consolidation and on disposal of a foreign operation, the gain or loss that is reclassified to profit or loss reflects the amount that arises from using this method.

(e) Use of estimates and judgements

In preparing these consolidated financial statements, management has made judgements, estimates and assumptions that affect the application of the Group’s accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to estimates are recognised prospectively.

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment in the year ending 31 December 2017 is included in the following notes: (a) Impairment (and impairment reversals) on oil and gas assets and concession rights.

Assets are impaired when there are events or changes in circumstances that indicate that carrying amounts of the assets are not recoverable. Such impairment indicators include changes in the Group’s business plans, changes in commodity prices leading to unprofitable performance and, for Oil & Gas properties, significant downward revisions of estimated proved reserve quantities or significant increase of the estimated development costs.

Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs of disposing of the asset. The value in use calculation is based on a DCF model. The expected future cash flows used for impairment analyses are based on judgmental assessments of future production volumes, prices and costs, considering available information at the date of review and are discounted by using a rate which considers the risks specific to the asset. For oil and natural gas properties, the expected future cash flows are estimated principally based on developed and undeveloped proved reserves including, among other elements, production taxes and the costs to be incurred for the reserves yet to be developed. The estimate of the future amount of production is based on assumptions related to the commodity future prices, lifting and development costs, field decline rates, market demand and other factors. The cash flows associated to Oil & Gas commodities are estimated on the basis of forward market information, if there is a sufficient liquidity and reliability level, on the consensus of independent specialized analysts and on management’s forecasts about the evolution of the supply and demand fundamentals. The discount rate reflects the current market valuation of the time value of money and of the specific risks of the asset not reflected in the estimate of the future cash flows

Consolidated IFRS FS 2017 FINAL 14 Partex Holding B.V.

The recoverable amount is sensitive to the discount rate used for the DCF model as well as the expected future cash-inflows and the growth rate used for extrapolation purposes.

The key assumptions used to determine the recoverable amount for the different CGUs, including a sensitivity analysis, are disclosed and further explained in Note 7.

(b) Income taxes The Group is subject to income taxes in certain jurisdictions. Significant interpretation and estimates are required in determining the group income taxes. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. Different interpretations and estimates would result in a different level of income taxes both current and deferred, recognized in the period. (c) Crude oil reserves The estimation of crude oil reserves is an integral part of the decision-making process relating to exploration activity and development assets. The volume of proved crude oil reserves is used to calculate depreciation of the exploration and production assets in accordance with the "Unit of Production" method, as well as to value impairment of investment in assets relating to that activity.

Estimated proved reserves are subject to future revision, as new information becomes available, including information relating to development activities, drilling or production, exchange rates, prices, contract termination dates and development plans. Changes in estimated proved reserves are taken into account in calculating depreciation and provision for abandonment by appropriately adjusting the remaining net book value of the assets being depreciated and the provision for abandonment costs- based on the expected future production.

(d) Environmental liabilities The Group makes judgments and estimates to calculate provisions for environmental matters, including decommissioning liabilities, based on current information relating to expected costs and plans. Such costs can vary due to changes in legislation and regulations relating to a specific location. Any change in the circumstances relating to such provisions, as well as in the legislation and regulations can significantly affect the provisions for such matters.

(e) Pension and other employee benefits Determining pension liabilities requires the use of assumptions and estimates, including the use of actuarial projections, estimated returns on investment, and other factors that could impact the cost and liability of the pension plan.

(f) Measurement of fair values As noted under item (b) above, the Group does not hold financial assets recorded at fair value, except for pension assets, which are outside the scope of IAS 39 “financial instruments: “measurement and recognition” and accounted for under IAS 19 “employee benefits”.

3 Significant accounting policies The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements and have been applied consistently by all Group companies.

(a) Basis of consolidation

(i) Subsidiaries The consolidated financial statements comprise the financial statements of the Company and its subsidiaries as at 31 December 2017. Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Generally, there is a presumption that a majority of the voting rights result in control. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. Non-controlling interest are measured initially at their proportionate share of the acquiree’s identifiable net assets at the date of acquisition. Profit or loss and each component of OCI are attributed to the equity holders of the parent of the Group and to the non-controlling interest, even if this results in the non-controlling interest having a deficit balance. When necessary, adjustments are made to the financial statements of the subsidiaries to bring their accounting policies in line with the Group Accounting policies. All intra group assets and liabilities, equity, income, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation.

(ii) Loss of control When the Group loses control over a subsidiary, it derecognises the assets and liabilities of the subsidiary, and any non-controlling interests and other components of equity. Any resulting gain or loss is recognised in profit or loss. Any interest retained in the former subsidiary is measured at fair value when control is lost.

(a) Companies with interest in oil concessions or contractual operations. (b) Supply of services. (c) Holding Company.

(iii) Interests in equity accounted investees A joint arrangement is present where the Group holds a long-term interest The Group’s interest in equity-accounted investees comprise interests in joint ventures. A joint venture is an arrangement in which the Group has joint control, whereby the Group has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities. Interests in joint ventures are accounted for using the equity method. Under the equity method, the investment is carried on the balance sheet at cost plus post acquisition changes in the group’s share of net assets of the entity, less distributions received and less any impairment in value of the investment. The Group income statement reflects the Group share of the results after tax of the equity accounted investment and the Group statement of comprehensive income includes the Group’s share of the equity accounted entity’s other comprehensive income. The equity accounted investee held by the Group relates to the following: Country of 2017 2016 Joint Venture Principal activity operation % % Oman LNG LLC Oman Gas exploration (development) 2% 2%

Consolidated IFRS FS 2017 FINAL 17 Partex Holding B.V.

(b) Revenue

Sale of goods In relation to oil and gas sales, revenue is recognised when significant risks and rewards of ownership have been transferred to the buyer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably. Revenue is measured net of returns, trade discounts and volume rebates. Revenue resulting from hydrocarbon production from properties in which the Group has an interest with partners in a joint arrangement is recognised based on the sales method, which implicates that the Group does not adjust the revenue for imbalances between the entitlement from the joint operation and actual quantities lifted, but actually adjusts for the (additional) costs incurred for production of these additional quantities. This implies that, where the Group has lifted and sold more than the ownership interest, an accrual is recognised for the cost of the overlift. Where the Group has lifted and sold less than the ownership interest, costs are deferred for the underlift.

Services Service arising from the Group’s resources are recognized upon delivery of the service and when it is probable that the economic benefits associated with the transaction will flow to the Group and the revenue can be measured reliably.

Dividends, rewards and other income related to Oil and Gas

Interest, dividends, royalties and rewards arising from the Group’s resources are recognised when it is probable that the economic benefits associated with the transaction will flow to the group and the revenue can be measured reliably.

(c) Finance income and finance costs Interest received comprise of interest income on cash and cash deposits, interest received for timing differences between actual and agreed payment dates, unwinding of discount on provisions and the reversal of discounted interest on financial assets which are measured at their net present values. Interest income is recognised as it accrues unless collectability is in doubt.

Financial expenses comprise interest expense on borrowings, cash overdrafts, timing differences between actual and agreed payment dates, discounting of provisions and financial assets measured at net present value. Interest expense is recognised as it accrues.

Consolidated IFRS FS 2017 FINAL 18 Partex Holding B.V.

(d) Foreign currency

(i) Foreign currency transactions Transactions in foreign currencies are translated into the respective functional currencies of Group companies at the transaction date. At the balance sheet date, monetary assets and liabilities are converted at the rate of exchange ruling at that date. Exchange differences are recognised in the income for the year. Non‐monetary assets and liabilities that are measured at historical cost in a foreign currency are translated using the exchange rate at the date of the transaction. Non‐monetary assets and liabilities denominated in foreign currencies that are stated at fair value are translated at the foreign exchange rates ruling at the dates the fair value was determined. The resulting exchange differences are accounted for in the income statement, except when related to equity instruments classified as available-for-sale, which are included in the fair value reserve.

(ii) Foreign operations

The assets and liabilities of foreign operations are translated into USD at the exchange rates of the reporting date. The income and expenses of foreign operations are translated into USD at the exchange rates at the dates of the transactions. Foreign currency differences are recognised in OCI and accumulated in the translation reserve, except to the extent that the translation difference is allocated to NCI. When a foreign operation is disposed of in its entirety or partially, such that control, significant influence or joint control is lost, the cumulative amount on the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. Exchange differences arising on a monetary item that forms part of the Group's net investment in a foreign operation are presented in the consolidated financial statements in other comprehensive income and reclassified from equity to profit or loss on disposal or partial disposal of the net investment.

(e) Employee benefits

(i) Short-term employee benefits Short-term employee benefits are expensed as the related service is provided. A liability is recognised for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

(ii) Pensions

The Group operates an unfunded defined benefits pension scheme for certain staff. Provision is made in the accounts for the Group’s obligations under the scheme, on the basis of an actuarial valuation. The provision represents the estimated present value of benefits to be paid to existing

Consolidated IFRS FS 2017 FINAL 19 Partex Holding B.V.

pensioners and of future benefits payable to current employees in respect of service up to the balance sheet date.

The pension liability is calculated annually at the balance sheet date using the projected unit credit method, by qualified actuaries. The discount rate used in the calculation is determined by reference to interest rates of high quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating to the terms of the related pension liabilities.

The annual costs of the scheme, the net total interest and current service costs, are charged to the income Statement.

Re-measurements of the defined benefit liability are included in the revaluation reserve, which compromise actuarial gains and losses recognised immediately in OCI.

(iii) Other long-term employee benefits The Group’s net obligation in respect of long-term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value. Re-measurements are recognised in profit or loss in the period in which they arise.

(f) Income tax Income tax expense comprise current and deferred tax. It is recognised in profit or loss, except to the extent that it relates to a business combination, or items recognised directly in equity or OCI. Current tax comprises the expected tax payable or receivable on the taxable income or loss for the year and any adjustment to the tax payable or receivable in respect of previous years. The amount of current tax payable or receivable is the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax assets and liabilities are offset only if certain criteria are met. Deferred tax is recognised in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax basis, and is calculated using the tax rates in force at the balance sheet date in the respective jurisdiction and that are assumed will apply when the related deferred income tax asset is realised or the deferred income tax liability is settled. Deferred tax liabilities are recognised for all taxable temporary differences except for goodwill which is not deductible for tax purposes, differences arising on initial recognition of assets and liabilities that affect neither accounting nor taxable profit and differences relating to investments in subsidiaries to the extent that they will probably not reverse in the foreseeable future. Deferred tax assets are recognised to the extent it is probable that future taxable profits will be available, from which deductible temporary differences can be deducted. The Company offsets deferred taxes assets and liabilities for each subsidiary, whenever (i) the subsidiary has a legally enforceable right to set off current tax assets against current tax liabilities, and (ii) they relate to income taxes levied by the same taxation authority. This offset is therefore

Consolidated IFRS FS 2017 FINAL 20 Partex Holding B.V.

performed at the level of each subsidiary: thus the deferred tax asset presented in the consolidated balance sheet is the sum of the subsidiaries that present deferred tax assets and the deferred tax liability is the sum of the subsidiaries that present deferred tax liabilities.

(g) Inventories Inventories are measured at the lower of cost and net realizable value. Cost of crude oil is determined using the first-in first-out cost method. Crude oil inventory consists of amounts in pipelines, tanks and stock held by transportation companies, where the right of ownership has not been transferred to the customers. The cost of crude oil inventory includes all direct costs and an appropriate share of overheads. Cost of other inventories is determined at cost using the weighted average cost method. Net realizable value is the estimated selling price in the ordinary course of business, less the cost of completion and selling expenses.

(h) Property, plant and equipment (as included in Oil & Gas properties) (i) Property, Plant, Equipment and depreciation Property, plant and equipment are measured at cost less accumulated depreciation and any accumulated impairment losses. Depreciation of oil and gas properties is calculated using the unit-of-production method based upon proved and probable developed reserves. The reserve estimates include only crude oil which management believes can reasonably be produced within the current terms of the respective production agreements. The reserves for this purpose are determined in accordance with generally accepted procedures in the oil and gas industry. Significant individual items of property, plant and equipment (components), except for oil and gas properties, whose useful lives are different from the useful life of the asset as a whole, are depreciated individually, applying depreciation rates reflecting their anticipated useful lives. The cost of replacing major parts or components of property, plant and equipment items is capitalised and the replaced part is retired. Any gain or loss arising is recognised in the income statement when the asset is retired. Subsequent costs are recognized as separate assets when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. All repair and maintenance costs are charged to the income statement during the financial period in which they are incurred. Depreciation is calculated using the straight-line method over the assets estimated useful life as follows: Number of Years/Method

Furniture and fixtures 4 to 6 Office equipment 4 to 6 Vehicles 3 to 4 Facilities and machinery (incl. in oil & Gas assets) Unit of production Wells (incl. in oil & Gas assets) Unit-of-production

Consolidated IFRS FS 2017 FINAL 21 Partex Holding B.V.

Depreciation is charged to the income statement on a straight line basis over the estimated useful life of the individual asset or a unit of depletion basis depending on the type of asset. Changes in estimates, which affect unit of production calculations, are taken into account for the year of the change and for future years. When there is an indication that an asset may be impaired, IAS 36 requires that its recoverable amount be estimated and an impairment loss recognized when the net book value of the asset exceeds its recoverable amounts. Recoverable amount is determined by greater of fair value less cost to sell and the value in use. Impairment losses are recognized in the income statement. On an annual basis the Group determines the value in use of (its share in) Oil & Gas assets relating to joint arrangements with third parties. Based on the recoverable amount determined from this calculation, the Group records an impairment on its (proportionate) share in the joint oil producing assets, if relevant.

In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. Expected cash flows are determined on the basis of reasonable and supportable assumptions that represent management’s best estimate of the range of economic conditions that will exist over the remaining useful life of the asset, giving greater weight to external evidence. With reference to commodity prices, management assumes the price scenario adopted for economic and financial projections and for whole life appraisal for capital expenditures. In particular, for the cash flows associated to oil, natural gas and petroleum products prices (and prices derived from them), the price scenario is approved by Management. When commodity prices fluctuate quite considerably, management considers the most updated variables available. The discount rate used is the Weighted Average Cost of Capital (WACC) adjusted for the specific country risk of the asset. These adjustments are measured considering information from external parties.

(i) Intangible assets and goodwill

The Group records its intangible assets at acquisition costs less accumulated amortization and impairment losses.

Exploration expenditure Exploration costs are accounted for under the successful efforts method for exploration and development activities from the start of the operation until the beginning of the production phase. Exploration expenditure is initially capitalized as an intangible asset until the drilling of the well is complete and the results have been evaluated. If hydrocarbons are not found, the exploration expenditure is written off as a dry hole. If hydrocarbons are found and, subject to further appraisal activity which may include the drilling of further wells, are likely to be capable of commercial development, the costs continue to be carried as an intangible asset. All such carried costs are subject to management review at least once a year to confirm the continued intent to develop or otherwise extract value from the discovery.

Consolidated IFRS FS 2017 FINAL 22 Partex Holding B.V.

When this is no longer the case, the costs are written off. When proved reserves of hydrocarbons are determined and these are considered commercially producible quantities of reserves and consequent development is determined, the respective expenditure is transferred to Oil and Gas properties.

Concession costs Concession acquisition costs are capitalized within intangible assets and are amortized over the useful life of the concession on a straight-line basis, which varies from 11 to 22 years.

Other intangible assets Other intangible assets that are acquired by the Group and have finite useful lives are measured at cost less accumulated amortisation and accumulated impairment losses.

Amortisation is calculated to write off the cost of intangible assets less their estimated residual values using the straight-line method over their estimated useful lives, and is generally recognised in profit or loss.

The estimated useful lives for the other intangible assets varies between 4 to 10 years. Amortisation methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.

(j) Financial instrument

Classification The Group classifies non derivative financial assets into the following categories: financial assets at fair value through profit and loss, held to maturity financial assets, loans and receivables and available for sale financial assets. The Group classifies non derivative financial liabilities into the following categories: financial liabilities at fair value through profit and loss and other financial liabilities. Non derivative financial assets and liabilities - Initial recognition, measurement and de- recognition The Group initially recognises loans and receivables and debt securities on the date when they are originated. All other financial assets and financial liabilities are initially recognised on trade date when the entity becomes a party to the contractual provisions of the instrument. The Group derecognises a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risk and rewards of ownership of the financial asset are transferred, or it neither transfers nor retains substantially all of the risk and rewards of ownership and does not retain control over the transferred asset. Any interest in such derecognised financial assets that is created or retained by the Group is recognised as a separate asset or liability. The Group derecognises a financial liability when its contractual obligations are discharged or cancelled, or expire.

Consolidated IFRS FS 2017 FINAL 23 Partex Holding B.V.

Financial assets and liabilities are offset and the net amount presented in the statement of financial position when, and only when, the Group currently has a legally enforceable right to offset the amounts and intends either to settle them on a net basis or to realise the asset and settle the liability simultaneously. Available for sale financial assets These financial assets are non-derivative financial assets (i) intended to be held for an indefinite period of time, (ii) designated as available-for-sale at initial recognition or (iii) that are not classified in the other categories referred to above. Available for sale financial assets are initially recognised at fair value plus transaction costs.

Available-for-sale financial assets are subsequently carried at fair value. However, gains and losses arising from changes in their fair value are recognised directly in the shareholders’ equity, until the financial assets are derecognised or impaired, at which time the cumulative gain or loss previously recognised in the shareholders’ equity is recognised in the income statement. Foreign exchange differences arising from equity investments classified as available-for-sale are also recognised in shareholders’ equity, while foreign exchange differences arising from debt investments are recognised in the income statement. Interest, calculated using the effective interest rate method, and dividends are recognised in the income statement. Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Such assets are initially recorded at fair value plus any directly attributable transaction costs and subsequently at amortized cost using the effective interest method. Gains and losses are recognized in income when the loans and receivables are derecognized or impaired, as well as through the amortization process. This category of financial assets includes trade and other receivables.

Financial liabilities An instrument is classified as a financial liability when it contains a contractual obligation to transfer cash or another financial asset, independently from its legal form. Non-derivatives financial liabilities include Group payables and other payables. The financial liabilities are recognised (i) initially at fair value less transaction costs and (ii) subsequently at amortised cost, using the effective interest rate method.

(k) Share capital

Ordinary shares Incremental costs directly attributable to the issue of ordinary shares, net of any tax effects, are recognised as a deduction from equity.

(l) Cash and cash equivalent Cash and cash equivalents comprise balances with a maturity of less than three months from the balance sheet date and include cash and deposits with banks.

Consolidated IFRS FS 2017 FINAL 24 Partex Holding B.V.

(m) Impairment The Group assesses periodically whether there is objective evidence that a financial asset or group of financial assets is impaired.

A financial asset or a group of financial assets is impaired if there is objective evidence of impairment as a result of one or more events that occurred after their initial recognition, such as: (i) for equity securities, a significant or prolonged decline in the fair value of the security below its cost, and (ii) for debt securities, when that event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets, that can be reliably estimated.

If there is objective evidence that an impairment loss on available-for-sale financial assets has been incurred, the cumulative loss recognised in the shareholders’ equity – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in the income statement – is taken to the income statement. If, in a subsequent period, the amount of the impairment loss decreases, the previously recognised impairment loss is reversed through the income statement up to the acquisition cost if the increase is objectively related to an event occurring after the impairment loss was recognised, except in relation to equity instruments, in which case the reversal is recognised in OCI.

(n) Leases The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease. The arrangement is, or contains, a lease if fulfilment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement.

(i) Group as lessee

A lease is classified at the inception date as a finance lease or an operating lease. A lease that transfers substantially all risks and rewards incidental to ownership to the Group is classified as a finance lease. Finance leases are capitalised at the commencement of the lease at the inception date fair value of the leased property or, if lower, at the present value of the minimum lease payments. Lease payments are apportioned between finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are recognised in finance costs in the statement of profit or loss. A leased asset is depreciated over the useful life of the asset. However, if there is no reasonable certainty that the Group will obtain ownership by the end of the lease term, the asset is depreciated over the shorter of the estimated useful life of the asset and the lease term. An operating lease is a lease other than a finance lease. Operating lease payments are recognized as an operating expense in the statement of profit or loss on a straight-line basis over the lease term.

Consolidated IFRS FS 2017 FINAL 25 Partex Holding B.V.

(ii) Group as lessor Leases in which the Group does not transfer substantially all the risks and rewards of ownership of an asset are classified as operating leases. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognised over the lease term on the same basis as rental income. Contingent rents are recognised as revenue in the period in which they are earned.

(o) Provisions

Provisions are recognised when the Group has a legal or constructive obligation, and it is probable that a cost will be incurred as a result of past events and a reasonable estimate can be made of the liability.

Provisions for asset retirement are measured based on current requirements, technology and price levels and the present value is calculated using amounts adjusted for expected future inflation and discounted over the useful economic life of the assets. The liability is recognised (together with a corresponding amount as part of the related property, plant and equipment) once an obligation crystallizes in the period when a reasonable estimate can be made. The effects of changes resulting from revisions to the timing or the amount of the original estimate of the provision are reflected through adjustments to the carrying amount of the related property, plant and equipment.

(p) Joint operations

Arrangements under which the Group has contractually agreed to share control with another party or parties are joint ventures where the parties have right to the net assets of the arrangement, or joint operations where the parties have rights to the assets and obligations for the liabilities relating to the arrangement. Investment in joint ventures are accounted for using the equity method.

The activities of a joint operation are primarily designed for the provision of output to the parties to the arrangement, indicating that: • the parties have the rights to substantially all the economic benefits of the assets of the arrangement; and • all liabilities are satisfied by the joint participants.

This indicates that, in substance, the joint participants have an obligation for the liabilities of the arrangement. Following the above, in accordance with IFRS 11 the Group consequently recognises its assets and liabilities relating to its interests in joint operations, including its share of assets held jointly and liabilities incurred jointly with other partners. Normally this leads to the accounting for the joint operation in a manner similar to the previous proportionate consolidation method. In addition to this, the Group recognises its revenue from the sale of its share of the output arising from the joint operation and its share of any expenses incurred.

The Group recognises its proportionate share in assets and liabilities relating to its interests in joint operations, including its share of assets held jointly with other partners in the oil producing assets.

Consolidated IFRS FS 2017 FINAL 26 Partex Holding B.V.

Significant joint operations of the Group, which are those with the most significant contributions to the Group’s net profit and/or net assets, are the following:

4 New standards and interpretations

(i) New and amended standards and interpretations

The Group applied for the first time certain amendments to the standards, which are effective for annual periods beginning on or after 1 January 2017. The Group has not early adopted any standards, interpretations or amendments that have been issued but are not yet effective.

The nature and the impact of each amendment is described below:

Amendments to IAS 7 Statement of Cash Flows: Disclosure Initiative

The amendments require entities to provide disclosure of changes in their liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes (such as foreign exchange gains or losses).

These amendments did not affect the Group’s financial statements since no liabilities arising from financing activities exist.

Amendments to IFRS 12 Disclosure of Interests in Other Entities: Clarification of the scope of disclosure requirements in IFRS 12 from Annual Improvements Cycle - 2014-2016

Consolidated IFRS FS 2017 FINAL 27 Partex Holding B.V.

The amendments clarify that the disclosure requirements in IFRS 12, other than those in paragraphs B10–B16, apply to an entity’s interest in a subsidiary, a joint venture or an associate (or a portion of its interest in a joint venture or an associate) that is classified (or included in a disposal group that is classified) as held for sale.

These amendments did not affect the Group’s financial statements since as at 31 December 2017 no interests in other entities are classified as held for sale.

Amendments to IAS 12 Income Taxes: Recognition of Deferred Tax Assets for Unrealised Losses

The amendments clarify that an entity needs to consider whether tax law restricts the sources of taxable profits against which it may make deductions on the reversal of deductible temporary difference related to unrealised losses. Furthermore, the amendments provide guidance on how an entity should determine future taxable profits and explain the circumstances in which taxable profit may include the recovery of some assets for more than their carrying amount.

Their application has no effect on the Group’s financial position and performance as the Group has no deductible temporary differences or assets that are in the scope of the amendments.

(ii) IFRS not yet effective

The standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Group’s financial statements are disclosed below. The Group intends to adopt these standards, if applicable, when they become effective.

IFRS 9 Financial Instruments

In July 2014, the IASB issued the final version of IFRS 9 Financial Instruments that replaces IAS 39 Financial Instruments: Recognition and Measurement and all previous versions of IFRS 9. IFRS 9 brings together all three aspects of the accounting for financial instruments project: classification and measurement, impairment and hedge accounting. IFRS 9 is effective for annual periods beginning on or after 1 January 2018. The most significant change to possibly effect the group relates to the impairment of financial assets, following the “expected credit loss” model prescribed in the standard. However, based on its current history of limited impairment of trade receivables, the Group expects the impact of IFRS 9 on impairment results of financial assets to be very limited.

With respect to the classification and measurement requirements of IFRS 9, the Group expects to continue measuring at fair value all financial assets currently held at fair value, which are currently considered limited and immaterial.

Loans as well as trade receivables are held to collect contractual cash flows and are expected to give rise to cash flows representing solely payments of principal and interest. Thus, the Group expects that these will continue to be measured at amortised cost under IFRS 9. The Group does not apply hedge accounting currently and therefore does not expect a significant impact as a result of applying IFRS 9.

IFRS 15 Revenue from Contracts with Customers

Consolidated IFRS FS 2017 FINAL 28 Partex Holding B.V.

IFRS 15 was issued in May 2014 and establishes a comprehensive framework for determining whether, how much and when revenue is recognised. It replaces existing revenue recognition guidance, including IAS 18, IAS 11 and IFRIC 13 (relating to Costumer loyalty programmes). IFRS 15 is effective for annual periods beginning on or after 1 January 2018.

Contracts with customers in which oil sales are delivered is considered the main revenue activity of the Group. The current revenue recognition method based on transfer of the risk and rewards of ownership does not differ significantly from the revenue recognition requirements of IFRS 15 (and therefore it is expected to have limited impact on the Group). The Group expects the revenue recognition to occur at a point in time when control of the asset is transferred to the customer, generally on delivery of the oil, which is the same revenue recognition moment currently used in the consolidated financial statements. In particular, the impact relates essentially to the accounting for agreements with partners within oil & gas operations, due to the fact that they do not meet the definition of a customer. In particular, the case concerns the accounting for amounts of production lifted by a partner within oil & gas operations different from its proportionate entitlement (the so called lifting imbalances), by recognizing revenues on the basis of the quantities actually sold (the so called sales method) instead of the entitled quantities (the so called entitlement method). Since the Group already adopted the sales method (as describe in Note 3 (b) no effect of applying the new standard at January 1, 2018 will occur.

IFRS 16 Leases

IFRS 16 introduces a single on-balance lease accounting model for lessees. A lessee recognises a right of use asset representing its right to use the underlying asset and a lease liability representing its obligation to make lease payments. There are optional exemptions for short term leases and leases of low value items. As a lessee, the Group can either apply the standard using a: 1.Retrospective approach; 2. Modified retrospective approach with optional practical expedients.

IFRS 16 replaces existing lease guidance including IAS 17, SIC 15 and SIC 27. The standard is effective for annual periods beginning on or after 1 January 2019. The Group plans to apply IFRS 16 initially on 1 January 2019, using the modified retrospective approach. Therefore, the cumulative effect of adopting IFRS 16 will be recognised as an adjustment to the opening balance of retained earnings at 1 January 2019, with no restatement of comparative information.

The Group has not finalised the full assessment of the potential impact on its consolidated financial statements, but based on the first analysis, the impact of this new standard is expected to be immaterial.

Total impairment losses/(reversals)for the year 775,445 (60,356,596)

The impairment loss (reversal) on the joint share in fixed assets of the Group was calculated by comparing the Group’s joint venture share in the net book value of the fixed assets with the fair value of the investment as per year end 2017. The recoverable amount of the investments was calculated by discounting the estimated free cash flows generated through the respective investment, considering the period until the end of the concession. In order to calculate the free cash flow the Group used an estimated Brent price projection for 2018 to 2022 which includes the projection of all market analyst available on Bloomberg. For the year 2018 this implicates an estimated average Brent price of USD 61.1 per bbl. For the period after 2022 an average real (nominal) growth rate of the Brent price of 1.6% (3.9%) was considered, which is in line with the latest Energy Information Administration (EIA) publication available from February 2018. The discount rate used for calculating the present value of the cash flows amounts to 10.4% for the Oman joint arrangements of PDO and Mukhaizna (2016:10%), 9.9% for the Abu Dhabi joint arrangement of GASCO (2015: 9.6%), 10.2% for the Kazakhstan joint arrangement of Dunga (2016: 10.5%) and 10.8% for the Brazilian joint arrangement of Potiguar (2016:11.4%) respectively. The value in use estimated for each investment as per 31 December 2017 and related sensitivity analysis is as follows: (i) The maximum (minimum) value shows the estimated value in use considering a price increase/(decrease) of 20% as compared to the base case scenario.

In 2016, impairment losses were recorded on capitalised exploration costs in Brazil and in Portugal, amounting to USD 2,755,669 and USD 17,252,663. The impairment charge in Portugal resulted from the contract termination in Algarve basin and the withdrawal from the concession agreements in Peniche basin. The intangible assets include capitalized exploration & evaluation costs and concession rights paid until now for our interests in Angola Block 17/06, amounting to USD 17,065,850 and USD 27,084,004, respectively (2016: USD 17,014,028 and USD 28,315,000). Block 17/06 is located in one of the more prolific exploration areas in deep-offshore South Atlantic eastern coast, the Lower Congo Basin. After the drilling of the seven (7) commitment wells the results showed five (5) discovered wells with estimated 2C resources of around 85 Mbbls of oil, 35 Mbbls of condensate and around 1 Tcf of non associated gas. As at 31 December 2017, the development of block 17/06 is suspended pending further evaluation of the economic and operating viability of the project based on the following facts: • In 2016 was issued the decree nº2/16 of 13 June 2016 related to the contractual and fiscal terms applicable to marginal oil discoveries; • At the end of 2017, an informal group composed by major oil companies, Sonangol, Minister of Petroleum was created with the support of the new Angola Government to actively discuss and present concrete measures to further develop the oil and gas industry (which aims also to open to private companies the exploration and production of gas resources); • Ongoing discussions between Operator, Contractor Group and Concessionaire to revise the current contractual and fiscal terms applicable to block 17/06. To be noted that recently the Angola Government demonstrated its willingness to maximize and preserve the future of the oil industry by revising the terms of other PSAs (Production Sharing Agreements); • End of 2017, the exploration and development expenditures for the next 5 years were submitted for Sonangol approval and foreseen the first oil in Begonia end of 2023; • Earlier in March 2018, the Operator submitted to Sonangol a new update of the development plan of one of the areas inside block 17/06 (Begonia), highlighting that further technical works to optimize costs (which may include a joint development with a nearby block), combined with contractual and fiscal enhancements are needed to enable any further appraisal and development. Management is fully confident on the success of the ongoing initiatives that will allow the future development of the project and the recoverability of the carrying amount.

A significant portion of the recoverable amount of Dunga field is attributed to the residual value related to the repayment of 50% of the total unrecovered capital expenditures at the end of the concession (1st of May 2024), estimated to be around USD 122 million.

Management notes that as per the Dunga Production Sharing Agreement (PSA), the Kazakh Party has the right (not the obligation) to acquire such equipment from Contractor for the unrecovered Recoverable Cost of such equipment. This entails the risk of negotiation and “cherry picking” by the Authority.

The Group, with its local partners, already secured a MoU with the local authorities to extend the concession for another 15-year term. This extension should be formally signed after a new law (RoK Code dated 27 December 2017 No 125-VI on Subsurface and Subsurface Use taking into account provisions regarding extension of the contract duration) comes into force in Kazakhstan in June 2018. With the extension until 2039, the alternative development plan, which was submitted in October 2016, foresees the full recoverability of the cost pool and a significant increase in the project economics. As such Management considers that the carrying amount will be fully recovered.

The Group has production facilities in Brazil where two fields are operated. The share on PDO, GASCO, Dunga and Mukhaizna property, plant and equipment is recorded under the terms of IFRS 11 with their respective proportional share of the values reported by the Company. The Company makes provision for the abandonment of wells (see note 20), dismantling of facilities, installations and to restore the exploration sites which has been capitalized in the corresponding assets, in the accumulated amount of USD 56,198,553 (2016: USD 58,849,943).

110,032,256 110,148,721

Staff pension joint operations The staff pension for joint operations relates to the pension obligation for Omani staff employees through Petroleum Development Oman (“PDO”). The Omani staff pension scheme is a defined benefit retirement scheme. The contribution by Omani staff is 7% of their basic salaries plus allowances whilst the contributions made by PDO are on the basis of actuarial valuations. The combines contributions are used to purchase investments, which are legally held in the name of PDO, on behalf of the pension scheme. As such, the value of these investments has a corresponding liability in relation to the pension obligations to employees. As at 31 December 2017, the fair value of the pension assets amounts to USD 45,418,480, with a corresponding liability in the staff pension for joint operations.

The assumptions used in the calculation of the pension liability were as follows:

2017 2016 Projected unit credit Discount rate 6.2% 6.2% Expected rate of return on assets 6.2% 6.2% Future salary increases 3.0% 3.0% Rate of pension increase 1% 1%

The Scheme exposes the Company to actuarial risks such as investment risk, longevity risk and salary risk.

Consolidated IFRS FS 2017 FINAL 45 Partex Holding B.V

Investment risk The present value of the defined benefit plan liability is calculated using a discount rate determined by reference to high quality bond yields; if return on plan asset is below this rate, it will create a plan deficit.

Interest risk A decrease in the bond interest rate will increase the plan liability; however, this will be partially offset by an increase in the return on the plan’s debt investments.

Longevity risk The present value of the defined benefit plan liability is calculated by reference to the best estimate of the mortality of plan participants both during and after their employment. An increase in the life expectancy of the plan participants will increase the plan’s liability.

Salary risk The present value of the defined benefit plan liability is calculated by reference to future salaries of the plan participants. As such, an increase in the salary of the plan participants will increase the plan’s liability

Significant actuarial assumptions for the determination of the defined obligation are discount rate, expected salary increase and mortality. The sensitivity analyses below has been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding all other assumptions constant.

- If the discount rate is 100 basis points higher (lower), the defined benefit obligation would increase by USD 11.1 million (decrease by USD 8.4 million) approximately. - If the expected salary growth increases (decreases) by 1%, the defined benefit obligation would increase by USD 4.3 million (decrease by USD 3.6 million). - If the expectancy increases (decreases) by one year for both men and women, the defined benefit obligation would increase by USD 0.8 million (decrease by USD 0.7 million).

In accordance with IAS 19, the Company’s pension provision as at 31 December 2017, is analysed as follows:

Pension provision group companies Until the end of the financial year 2016, one of the subsidiaries of the Group operated a defined benefit obligation plan for certain of its current and prior employees. The cost of providing benefits under this plan was calculated using the projected unit credit method. In prior years, until the end of 2016 financial year, the Group has fully provided for the liability arising from this arrangement based on a third-party actuary report. As per the end of 2016, the pension plan, and accordingly the obligations arising from this plan, have been transferred to the shareholder of the Group.

The assumptions used in the calculation of the pension liability, before derecognition and subsequent transfer to the shareholder, were as follows:

Financial risk management

The Group has exposure to the following risks arising from financial instruments:

• credit risk; • liquidity risk; • market risk.

Risk management framework The Board of Directors has overall responsibility for the establishment and oversight of the Group’s risk management framework and Risk Management Policies. The Group’s risk management policies are established to identify and analyse the risks faced by the Group, to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Group’s activities. The Group, through its training and management standards and procedures, aims to develop a disciplined and constructive control environment in which all employees understand their roles and obligations. Credit risk Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally from the Group’s receivables from customers and financial assets. On an ongoing basis the Group carefully assesses the quality of its counterparties when entering upon and during the business relationship. The carrying amount of financial assets represents the maximum credit exposure. With the vast majority of the Group’s customers a long term co-operation has been established and no impairment loss has been recognised against these customers since. At 31 December 2017, the maximum exposure to credit risk for trade and other receivables by geographic region was as follows:

At 31 December 2017, the Group’s most significant customer accounted for USD 19,457 thousand of the trade and other receivables carrying amount (2016: USD 21,046 thousand). Impairment Based on the subsequent receipt of customer receivables and prior year experience, management estimates that no impairment of the Oil & Gas receivables is considered necessary by the end of the financial year 2017 (2016: nil). Cash and cash equivalents The Group held cash and cash equivalents of USD 74,700 thousand at 31 December 2017 (2016: USD 63,265 thousand). The cash and cash equivalents are held with banks with solid credit ratings (A-). Liquidity risk Liquidity risk is the risk that the Group will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Group’s approach to managing liquidity is to ensure, as far as possible, that it will have sufficient liquidity to meet its liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Group’s reputation. The liquidity risk is monitored on local as well as Group consolidated level by means of liquidity and cash flow forecasting per relevant entity. Through this, local funding needs are determined and anticipated. Management of the Group is continuously reported and updated on the liquidity status of the Group. The Group believes that it has access to sufficient sources of funding to meet current commitments. Exposure to liquidity risk At 31 December, the exposure to liquidity risk is as follows:

Market risk Market risk is the risk that changes in market prices – such as foreign exchange rates, interest rates and equity prices – will affect the Group’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimising the return. Currency risk The Group is exposed to currency risk to the extent that there is a mismatch between the currencies in which sales, purchases and borrowings are denominated and the respective functional currencies of Group companies. The functional currencies of Group companies are primarily US Dollars. The currencies in which these transactions are primarily denominated are US Dollars and Euros. Exposure to currency risk The summary of quantitative data about the Group’s exposure to currency risk as reported to the management of the Group is as follows:
