Corporate & Finance Overview

In H1 2019, improved production performance has allowed investment in additional growth whilst giving flexibility to make long-term investment decisions that offer the Company the opportunity for continued shareholder returns.

Through managing the portfolio our investment approach ensures we apply strict capital discipline to maintain appropriate balance sheet strength. Our full cycle, sustainable business model enables us to leverage success and we continue to optimise and where appropriate expand the asset base.

By continuing to build and diversify the exploration portfolio, we have established attractive positions across ten countries with up to 14 wells planned in 2019-2020. Cairn seeks to participate in a range of exploration opportunities from early entry in frontier basins, to taking significant positions in emerging and mature basins and aims to deliver a material ongoing programme of operated and non-operated wells.

Current sources of funding include cash of US$58m at the half year end and the US$575m RBL facility of which US$60m has been drawn. The group also has a NOK700m Norway Exploration Finance Facility, which is available to finance future tax refunds on Norwegian exploration expenditure, of which NOK344m (US$40m) is currently drawn.

During H1, we were pleased to see strong production from our UK assets, generating oil and gas sales of US$257m and cash inflows of US$177m. Average oil prices for H1 were US$67.84 per boe (before a US$0.75 gain on hedging). Average production costs were US$16.73 per boe.

At 30 June 2019, Cairn has hedged 3.4 mmbbls of future production through to December 2020 using collar structures with a weighted average floor of US$64.53 per bbl and an average ceiling of US$78.83 per bbl.

Capital expenditure for the full year 2019 is expected to be US$295m, including US$25m anticipated expenditure on Kraken and Catcher, US$105m on the Senegal and Nova developments and forecast E&A expenditure of up to US$165m. Capital expenditure in H1 2019 was US$135m (US$121m net of future Norwegian tax refunds).

Production

In H1 oil and gas production averaged 23,700 boepd net to Cairn, up 15% on the previous six months. To date in Q3 we have continued to see exceptional uptime on Catcher and significantly improved facilities performance at Kraken and as a result, are upgrading 2019 full year production guidance to 21,000-23,000 bopd net. Both fields have further investments planned with additional drilling opportunities in 2020 to help maximise recovery.

Catcher

Catcher's 99% operating efficiency, coupled with the Excess Production Amendment agreed with the FPSO owner, has allowed sustained production at 66,600 bopd gross (13,300 bopd net) in H1. The formal approval for the satellite fields, Catcher North and Laverda has been received which will help to sustain production rates. These two wells together with the Varadero infill well are scheduled to spud in Q2 2020 with first oil targeted in 2021. A 4D seismic survey across the Catcher Area is scheduled for mid-2020 to help confirm additional future infill well locations.

Kraken

Average gross production in the six months to June 2019, was more than 32,700 bopd (9,650 bopd net). Significantly improved facilities performance at Kraken together with the DC4 wells coming online has resulted in more continuous periods with production rates above 40,000 bopd being achieved. Additional drilling opportunities are maturing in the Western flank where development drilling of a producer-injector pair through spare capacity in the existing DC2 sub-sea infrastructure is planned for 2020. Kraken crude pricing continues to strengthen internationally in light of the current heavy oil market.

Developments

Senegal

The SNE field development first phase remains on schedule, targeting first oil in 2022 with expected gross production of 100,000 bopd. The JV submitted an updated SNE Exploitation and Development Plan to the Ministry of Petroleum and Energies in August 2019 in order to meet changes and further details requested by the Ministry ahead of approval. The JV is targeting the Final Investment Decision in H2 2019 and is progressing finance arrangements including project financing.

Diamond Offshore was awarded the development drilling contract in Q2 2019 with phased drilling targeted to commence in Q1 2021. Two Diamond drill ships, Ocean BlackRhino and Ocean BlackHawk, will undertake this programme. Halliburton and BHGE have been awarded the main Drilling Services contracts. Shearwater was awarded a high-density multi-azimuth 3D seismic acquisition contract over the SNE field and neighbouring FAN discovery. Data acquisition for this survey commenced in H2. The subsea and FPSO FEED activities have progressed well and are now complete.

Norway

The Nova development is on schedule with first oil targeted in 2021 and has expected gross recoverable reserves of 80m boe, of which the majority will be oil.

In August, Cairn entered into an agreement for the sale of a 10% WI in the Nova development to ONE-Dyas Norge AS for US$59.5m plus working capital adjustments, which is expected to increase group liquidity by US$100m. Following this transaction, Cairn retains a participating interest of 10% in the Nova development. The transaction remains subject to the written consent of the Norwegian Ministry of Petroleum and Energy.

Nova is anticipated to deliver peak production of 50,000 bopd (net to Cairn 5,000 bopd). The first project milestone was achieved in H1 with two subsea templates installed on the ocean floor. This unlocked the next phase of the field development with 65km of pipelines laid in preparation for tie-back to the nearby Gjøa platform. Gjøa will receive the well stream and provide water injection and gas lift to the Nova field. A new module will be lifted onto Gjøa in 2020. Further satellite developments planned to be tied back to Gjøa have been submitted to the NPD with a likely positive impact on the operating expenditure and field life of the Nova.

Exploration

LATAM Exploration

Mexico

Since the opening of the region to international oil companies for the first time, there have been only five exploration wells drilled by IOCs in the Sureste Basin with more than 25 planned in the next five years. This compares to more than 3,000 wells in the US Gulf of Mexico in the last 35 years. Cairn now holds a material shallow water footprint in one of the world's most prolific hydrocarbon provinces.

Cairn has a position in four blocks (7, 9, 10 and 15) in the Gulf of Mexico, two as operator and two as non-operator. Mexico provides an exciting opportunity to discover commercial quantities of hydrocarbons in an under-explored region.

Cairn is targeting an estimated gross mean prospective resource of 550 mmboe in the 2019 drilling programme due to commence in September. The two operated wells on Block 9 will be drilled on the Alom and Bitol prospects with the Maersk Developer semi-submersible rig. Contingent on the success of this exploration campaign, Cairn will seek to expediate the appraisal of any discovery.

Non-operated drilling activity will run in parallel on Blocks 7 and Block 10 where two Eni operated wells are expected to commence in Q4 2019.

In August 2019, Cairn agreed a farm-in agreement with ENI to swap 15% of Cairn's interest in Block 9 for 15% of ENI's interest in Block 10. On completion, this transaction will result in Cairn holding a reduced interest of 50% on Block 9 and a new interest of 15% on Block 10 (subject to Government approval).

Cairn operates an additional licence in Mexico on Block 15 (50% WI) located in the shallow water Tampico-Misantla Basin, north-west of the Sureste Basin interests. In August 2019 the regulator, Comisión Nacional de Hidrocarburos, approved the exploration plan with work commitments comprising the purchase of 3D seismic data and an environmental baseline survey, both of which have been completed. Further evaluation of the Block is ongoing.

Suriname

In Suriname (Cairn 100% WI), a 4,500 km 2D seismic survey was acquired in H1. Fast track processing was completed and fully processed products will be delivered in Q4 2019. This new data will be incorporated into block wide interpretations, leading to an updated prospect inventory and decision on future 3D seismic acquisition.

Nicaragua

In H1, Cairn secured all consents to complete a farm-in to a 35.1% WI of the Equinor operated exploration blocks in the Sandino Basin, offshore Nicaragua's Pacific coast. The partnership has recently completed the acquisition and processing of a modern 3D seismic survey which has provided further encouragement to support exploration drilling.

East Atlantic Exploration

Côte d'Ivoire

Cairn has entered into the frontier onshore rift play which is adjacent to an established hydrocarbon province with both oil and gas production. Cairn's farm-in for a 30% WI in all seven of Tullow Oil's onshore licences was completed in H1. A 2D seismic acquisition programme which includes passive seismic acquisition, is expected to commence in coming months, subject to the receipt of regulatory approvals. The acquisition will be phased, beginning in the eastern blocks (CI-520-CI-522) and due to be completed in 2020.

Israel

Following the end of the reporting period and subject to final completion matters, Cairn was awarded eight licences offshore Israel in the country's second offshore bid round. Cairn is Operator of the licences with a 33.34% WI alongside two JV partners: Ratio Oil Exploration with 33.33% WI, which together with partners discovered one of the world's largest deep-water gas discoveries, Leviathan, offshore Israel; and SOCO International plc with 33.33% WI.

UK & Norway Exploration

One exploration well was completed in Norway in H1: PL885 (30% WI) containing the Presto prospect which was unsuccessful. A further two exploration wells have been completed so far in Norway in Q3 2019: PL758 (Cairn Operator 50% WI) containing the Lynghaug and PL842 (Cairn Operator 40% WI) containing the Godalen prospect. Both wells were unsuccessful, there were no traces of petroleum and the wells were classified as dry.

Drilling is about to commence on a well on P2312 (45% WI), targeting the Chimera prospect which is the Company's second operated well in the UK North Sea. The well is targeting a material prospect of 150 mmbbls gross with stand-alone development potential. The well is being drilled by the Stena Don and operations are expected to complete in Q4 2019.

Cairn was awarded the two licences it applied for in the UK Frontier 31(st) Offshore Licensing Round in H1: Operatorship and 100% WI in the Mane licence which is located close to Chimera and 50% WI and Operatorship in the East Orkney Basin licence.

In 2020, Cairn expects to continue an exploration campaign across the UK & Norway region with two firm wells.

India

There is no change in outlook with regard to the Indian arbitration. Drafting of the award by the Tribunal is ongoing and Cairn continues to have a high level of confidence in the merits of its claim. Cairn is seeking full restitution for losses totalling more than US$1.4bn resulting from India's expropriation of its investments in India in 2014, and India's unfair and inequitable treatment of those investments, due to the imposition of retrospective tax measures.

(2) Working interest share of cargoes sold during the period, net of FlowStream entitlement

(3) Excluding hedging gains of US$0.75/boe (2018 full year: costs of US$1.34/boe; 2018 half year: costs of US$0.84/boe)

(4) Production costs include cost of sales plus right-of-use asset lease repayments; total lease costs of US$8.92/boe (2018 full year: US$10.46/boe; 2018 half year US$12.43/boe)

Production

During the first half of 2019, daily production volumes on both assets have increased significantly. Catcher production averaged 70,200 boepd gross for the first half of the year and Kraken averaged more than 32,700 bopd for the period.

Revenue

Revenue from the sale of oil and gas was US$257.1m in the six months to 30 June 2019, before adjusting for hedging gains of US$2.9m. Release of deferred revenue of US$9.7m and royalty income in Mongolia of US$0.6m, increased total revenue to US$270.3m.

Cost of sales

Total production costs of US$33.8m include US$10.1m of variable lease payments on the Catcher and Kraken FPSOs. Following adoption of IFRS 16, both the Kraken and Catcher FPSOs are recorded as right-of-use assets in the Balance Sheet with lease liabilities recognised representing minimum payments due over the expected life of the lease contract. Previously, Catcher was accounted for as an operating lease, with all payments charged direct to production costs. Comparative information in the financial statements has not been adjusted.

Movements in oil inventory and overlift/underlift positions, measured at market value, of US$9.8m were credited against cost of sales in the period.

The increased depletion and amortisation cost per boe arises from the capitalisation and subsequent amortisation of the right-of-use asset in relation to the Catcher FPSO.

Net cash inflow from operating activities and cash generated from oil and gas production

Reported net cash inflow from operating activities for the period of US$172.9m reflects net cash generated from oil and gas sales after deducting administrative costs. After adding back administrative costs and pre-award expenditure, and deducting lease payments, net cash inflow from oil and gas production was US$176.6m.

(4) Cash balance of US$57.8m offset by US$60m of drawings under the RBL facility

Cairn had net debt of US$2.2m at 30 June 2019, representing a net cash inflow of US$16.5m over the six-month period. Borrowings under the Group's RBL facility at 30 June 2019 were US$60m, before adjusting for unamortised facility fees and accrued interest, representing a net repayment of US$25m in the period. Closing net cash and long-term borrowings presented above exclude US$39.6m drawn under the Norwegian Exploration Finance Facility ("EFF") which are advances secured against tax refunds due from the Norwegian government and are not considered a true reflection of the Group's current indebtedness.

There were no changes to the terms of either the RBL or EFF during the period.

Cash outflows on exploration expenditure in the period include US$22.6m of UK & Norway costs primarily relating to the unsuccessful wells in Norway, US$28.7m on completion of farm-ins in Nicaragua and Côte D'Ivoire and US$11.0m in advance of drilling in Mexico, with the balance of US$7.5m on the Group's remaining exploration licence and licence options in Suriname, Ireland and Mauritania.

Development and pre-development cash outflows in the period primarily relate to costs on Kraken, Nova and Senegal. On Kraken, cash spend of US$17m included the completion of final development drilling on Drill Centre 4 and on Nova cash expenditure of US$26.8m was incurred as the development progresses. Cash outflows in relation to Senegal pre-development of US$19.7m included FEED costs prior to FID approval expected later this year.

* after opening IFRS 16 adjustment

Exploration and appraisal asset additions in the UK & Norway include costs of the three exploration wells that were either completed or had commenced in the period. In LATAM, US$22.1m of costs relate to Nicaragua following the farm-in to four non-operated blocks and US$5.5m was incurred in Suriname following the 2018 farm-in to the B61 licence. The remaining LATAM costs of US$9.6m were spent in Mexico in advance of exploration drilling commencing this year.

In the East Atlantic segment, US$8.7m was incurred following the completion of the farm-in to seven non-operated licences in Côte D'Ivoire and the balance of US$2.5m on licence options in Mauritania and Ireland.

Senegal activities reflect the continuing work on development planning following the transfer of the operatorship of the licence to Woodside.

Development additions in the period totalling US$68.7m include the completion of development drilling on Kraken and related increases to the decommissioning asset and costs incurred on the Nova development. Spend on Catcher was minimal during the period.

Subsequent to the period-end Cairn has entered into four asset-related transactions for which approval from relevant authorities is awaited: the farm-down of the Group's working interest in the UK Laverda discovery to equalise its interests with the main Catcher development, the farm-down of a 15% working interest in the UK Chimera licence, the sale of a 10% working interest in the Norwegian Nova development and a swap of a 15% working interest in Block 9 in Mexico for the same working interest in neighbouring Block 10. Of the four, only the Nova sale is expected to have a material impact on the financial statements, where a gain on sale of US$31m is forecast.

Cairn has reviewed all exploration/appraisal and development/producing assets for indicators of impairment, testing for impairment where an indicator was identified. No impairment was recorded. This reflects relatively stable market conditions and performance from assets in line with or above expectation. The Group's oil price assumption remains unchanged at the three-year Brent forward curve then US$70 per bbl long term.

Pre-award costs reflect ongoing activity as Cairn seeks new opportunities to add to its portfolio of assets. Subsequent to the period-end Cairn was awarded eight licences offshore Israel.

Unsuccessful exploration costs, relating almost exclusively to the UK & Norway region, include costs written off on the Lynghaug, Presto and Godalen wells offshore Norway of US$12.3m, US$7.9m and US$3.7m respectively. The balance of US$1.3m was expensed on other licences where no further exploration activities are planned.

Related tax credits reflect Norwegian current tax refunds receivable on qualifying exploration and administrative expenses.

Taxation

During the period, Cairn made a UK ring fence profit in the period which was fully offset by brought forward losses. At 30 June 2019, Cairn had total UK ring fence losses of US$795.0m and supplementary charge losses of $710.4m. US$795.0m of UK ring fence losses as well as $317.9m of supplementary charge losses are recognised as deferred tax assets to fully offset deferred tax liabilities of US$270.3m. The remaining supplementary charge tax losses of US$392.4m, the activated investment allowance total of $627.4m and the deferred tax impact of the decommissioning liability represent an unrecognised deferred tax asset of US$159.3m at 30 June 2019.

A cash tax refund is receivable in Norway in respect of 78% of qualifying exploration and overhead spend. US$13.7mm of tax credits are recorded for amounts receivable relating to the current period. Norwegian deferred tax liabilities at 30 June 2019 of US$57.6m reflect timing differences on the carrying value of exploration assets where either a tax refund has been claimed or an uplift is available on capital spend.

Board Changes

In H1, Cairn announced the appointment of two new independent non-executive directors: Catherine Krajicek and Alison Wood who joined the Board with effect from 1 July 2019. Alison Wood is a member of the Company's audit committee. Alexander Berger served on the Board for nine years as non-executive director and retired from the Company at the AGM in May 2019.

Environmental Social Governance (ESG)

Our approach is governed by our commitment to working responsibly in all of our activities. Our culture is based on our longstanding core values, known as the 3Rs which stand for: building Respect, nurturing Relationships and acting Responsibly.

We recognise that internationally agreed climate change targets will require a significant transition to alternative sources of energy across the world. However, oil and gas will continue to play a critical role in meeting growing global energy demand during that transition period and Cairn will help meet that demand safely and responsibly.

We are committed to working to International Finance Corporation (IFC) Performance Standards on Social and Environmental Sustainability, which are in line with the UN Global Compact principles. Since 2012 we have also been a participating company in the Extractive Industries Transparency Initiative (EITI) which is a coalition of governments, companies and civil society that have adopted a joint approach to applying the EITI global standard, promoting transparency of payments in the oil, gas and mining sectors.

Our (non-operated) Catcher and Kraken assets come under the EU Emissions Trading Scheme Regulations.

We will continue to work to better understand and respond to the climate change associated challenges facing the industry. We will continue to work to global standards and reaffirm our commitment to the United Nations Global Compact, a voluntary initiative based on CEO commitments to implement universal sustainability principles in support of UN goals. These topics are considered by the Senior Executives and Board on a regular basis

Principal risks and uncertainties

Managing the Group's key risks and associated opportunities is essential to Cairn's long-term success and sustainability. The Group endeavours to pursue investment opportunities which offer an appropriate level of return whilst ensuring the level of associated political, commercial and technical risk remains within the defined risk appetite of the Group.

The Group's risk management framework provides a systematic process for the identification and management of the key risks and opportunities which may affect the delivery of the Group's strategic objectives. Key Performance Indicators are set annually, and determining the level of risk the Group is willing to accept in the pursuit of these objectives is a fundamental component of the Group's risk management framework.

Overall responsibility for the system of risk management and internal control and reviewing the effectiveness of such systems rests with the Board. Principal risks, as well as progress against key risk projects, are reviewed at each Board meeting and at least once a year the Board undertakes a risk workshop to review the Group's principal risks. This integrated approach to risk management has been and continues to be critical to the delivery of strategic objectives.

Responding to Changing Risks during H1 2019

Cairn has assessed the principal risks and uncertainties at the end of H1 2019 and concluded that the principal risks identified at 2018 year-end remain relevant. The principal risks are:

   --      Lack of exploration success 
   --      Volatile oil and gas prices 
   --      Securing new venture opportunities 
   --      Delay in Senegal development plan approval 
   --      Kraken and Catcher operational and project performance 
   --      Reliance on JV operators for asset performance 
   --      Health, safety, environment and security 
   --      Fraud, bribery and corruption 
   --      Inability to secure or repatriate value from India 
   --      Political and fiscal uncertainties 
   --      Access to debt markets

Independent review report to Cairn Energy PLC

Report on the consolidated financial statements

Our conclusion

We have reviewed Cairn Energy PLC's consolidated financial statements (the "interim financial statements") in the half-year report of Cairn Energy PLC for the 6-month period ended 30 June 2019. Based on our review, nothing has come to our attention that causes us to believe that the interim financial statements are not prepared, in all material respects, in accordance with International Accounting Standard 34, 'Interim Financial Reporting', as adopted by the European Union and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

What we have reviewed

The interim financial statements comprise:

   --    the group balance sheet as at 30 June 2019; 

-- the group income statement and group statement of comprehensive income for the period then ended;

   --    the group statement of cash flows for the period then ended; 
   --    the group statement of changes in equity for the period then ended; and 
   --    the explanatory notes to the interim financial statements. 

The interim financial statements included in the half-year report have been prepared in accordance with International Accounting Standard 34, 'Interim Financial Reporting', as adopted by the European Union and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority.

As disclosed in note 1 to the interim financial statements, the financial reporting framework that has been applied in the preparation of the full annual financial statements of the Group is applicable law and International Financial Reporting Standards (IFRSs) as adopted by the European Union.

Responsibilities for the interim financial statements and the review

Our responsibilities and those of the directors

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

Our responsibility is to express a conclusion on the interim financial statements in the half-year report based on our review. This report, including the conclusion, has been prepared for and only for the company for the purpose of complying with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority and for no other purpose. We do not, in giving this conclusion, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.

What a review of interim financial statements involves

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, 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.

We have read the other information contained in the half-year report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial statements.

Section 1 - Basis of Preparation

   1.1       Accounting Policies 

Basis of preparation

The half-yearly condensed consolidated Financial Statements for the six months ended 30 June 2019 have been prepared in accordance with the Disclosure and Transparency Rules of the Financial Conduct Authority and with International Accounting Standard IAS 34, 'Interim financial reporting', as adopted by the European Union. They should be read in conjunction with the annual Financial Statements for the year ended 31 December 2018, which have been prepared in accordance with International Financial Reporting Standards ('IFRS') as adopted by the European Union.

This half-yearly report was approved by the Directors on 9 September 2019.

The disclosed figures, which have been reviewed but not audited, are not statutory accounts in terms of Section 434 of the Companies Act 2006. Statutory accounts for the year ended 31 December 2018, on which the auditors gave an unqualified audit report, which did not contain an emphasis of matter paragraph or any statement under section 498 of the Companies Act 2006, have been filed with the Registrar of Companies.

This half-yearly report has been prepared on a basis consistent with the accounting policies expected to be applied for the year ending 31 December 2019, and uses the same accounting and financial risk management policies and methods of computation as those applied for the year ended 31 December 2018, other than changes to accounting policies resulting from the adoption of new or revised accounting standards.

The impact on the Financial Statements of the adoption of IFRS 16 'Leases' on 1 January 2019 can be found in note 1.3. Other changes to IFRS effective 1 January 2019 have no significant impact on Cairn's accounting policies or Financial Statements.

Significant key estimates and assumptions are unchanged from those applied in the year ended 31 December 2018 and the same have accordingly been applied here. Key estimates and assumptions applied on the adoption of IFRS 16 are detailed in note 1.3.

   1.2       Going Concern 

The Directors have considered the factors relevant to support a statement of going concern.

In assessing whether the going concern assumption is appropriate, the Board considered the Group cash flow forecasts under various scenarios, identifying risks and mitigating factors and ensuring the Group has sufficient funding to meet its current and contracted commitments as and when they fall due for a period of at least 12 months from the date of signing these Financial Statements.

The Directors have a reasonable expectation that the Group will continue in operational existence for this 12-month period and have therefore used the going concern basis in preparing the Financial Statements.

   1.3       Adoption of IFRS 16 'Leases' 

Cairn has adopted IFRS 16 'Leases' with effect from 1 January 2019. Cairn has chosen to apply IFRS 16 retrospectively with the cumulative effect of initial application recognised at the date of adoption. In doing so Cairn has elected not to re-assess whether contracts contain a lease.

IFRS 16 introduces a single lessee accounting model and requires a lessee to recognise assets and liabilities for all leases with a term of more than 12 months, unless the underlying asset is of low value. A lessee is required to recognise a right-of-use asset representing its right to use the underlying leased asset and a lease liability representing its obligation to make lease payments.

In assessing the impact of IFRS 16, Cairn identified the following assets where right-of-use assets and lease liabilities are recognised on adoption:

   -       Accounting for the FPSO on the UK Catcher producing asset; and 

- Accounting for non-cancellable leases of the Group's office premises in Edinburgh, London, Stavanger and Mexico City.

All other leases identified have either yet to commence on the date of adoption, are for periods of less than one year, have less than one year remaining on the date of adoption or are for low-value items which have no material impact on the Group's Financial Statements.

In applying IFRS 16, Cairn has used the following practical expedients permitted by the standard:

- Accounting for leases with a remaining term of less than 12 months at 1 January 2019 as short-term leases; and

- The exclusion of initial direct costs for the measurement of the right-of-use assets at the date of adoption.

Cairn has also chosen to measure the right-of-use assets recognised at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments, immediately before the date of adoption for all right-of-use assets recognised. There is therefore no adjustment to opening retained earnings.

Section 1 - Basis of Preparation (continued)

   1.3       Adoption of IFRS 16 'Leases' (continued) 

Kraken FPSO

Under IFRS 16, the carrying amount of a right-of-use asset and lease liability for leases previously classified as finance leases is equal to the carrying amount of the lease asset and lease liability immediately before the date of adoption. Therefore, the adoption of IFRS 16 has no impact on the right-of-use asset and lease liability previously recognised for the Kraken FPSO.

Catcher FPSO

Cairn has recognised a lease liability and a corresponding right-of-use asset of US$147.5m for the Catcher FPSO on adoption of IFRS 16. The Catcher FPSO lease was previously classified as an operating lease under IAS 17.

The key estimates and assumptions applied in measuring the right-of-use asset and lease liability were as follows:

- The minimum lease commitment is equal to 75% of the contracted day rate with all payments in excess of the minimum being classified as variable lease payments dependent upon performance;

- The lease term is equal to the current non-cancellable period of the lease with no reasonable plans to extend the lease contract beyond the initial term;

   -       No exercise of the option to purchase at the end of the initial term; and 

- The interest rate applied is equal to the Group's incremental borrowing rate on the date of adoption rather than a rate implicit in the lease contract which could not be readily determined.

The right-of-use asset is being amortised on a unit-of-production basis in accordance with the Group's accounting policy.

Other Property, Plant & Equipment - Leasehold Property

The Group recognised lease liabilities and corresponding right-of-use assets of US$10.0m in relation to leasehold premises.

The key estimates and assumptions applied in measuring these right-of-use assets and lease liabilities were as follows:

- The lease term is equal to the current non-cancellable period of the lease with no reasonable plans to extend the lease contract beyond the initial term for any of the Group's office premises;

- The interest rate applied is equal to the Group's incremental borrowing rate on the date of adoption rather than a rate implicit in the lease contracts where this could not be readily determined.

The assets will be amortised on a straight-line basis over the remaining life of the leases.

Adjustments recognised on adoption of IFRS 16: Reconciliation to 2018 Operating lease commitment

A reconciliation of operating lease commitments at 31 December 2018 to the opening lease liabilities on adoption of IFRS 16 is as follows:

As explained in note 4.1 the International Segment has now been separated into two business units, 'East Atlantic' (which includes the Group's exploration assets in Ireland, Mauritania, and Cote D'Ivoire) and 'LATAM' (which includes Latin American assets in Mexico, Nicaragua and Suriname).

Senegal

Additions in the period of US$21.5m have mainly been incurred for exploitation and pre-development costs.

UK & Norway

During the period the Group participated in two Norwegian exploration wells: PL758 Lynghaug and PL885 Presto. Subsequent to the period-end a third Norwegian well, PL842 Godalen, also completed. Additions in the period of US$20.6m include US$13.2m relating to the three wells, including costs of US$8.5m in respect of short-term leases, primarily for drilling rigs. All three wells were unsuccessful and costs of US$24.6m have been charged to the Income Statement.

LATAM (Latin America)

Additions in the period include US$22.1m following the farm-in to non-operated licences in Nicaragua, US$9.6m incurred in Mexico in advance of exploration drilling commencing in the second half of 2019 and US$5.5m in Suriname, of which US$3.9m was on the acquisition of seismic.

East Atlantic

Additions in the period of US$11.2m include US$8.7m in Côte D'Ivoire following the farm-in to seven non-operated licences.

Impairment review

At 30 June 2019, Cairn reviewed its intangible exploration/appraisal assets for indicators of impairment, and where indicators were identified, performed impairment tests. An indicator of impairment was identified on the UK Laverda asset which is allocated to the Catcher cash-generating unit for impairment testing. No impairment was recorded from the subsequent test. Sensitivity analysis performed using downward oil-price sensitivities consistent with those run at the 31 December 2018 year end did not identify impairment under any of these scenarios.

Additions during the period include a non-cash increase of US$28.5m for decommissioning estimates and US$39.9m of development activity spend funded through cash and working capital.

Impairment review

Impairment reviews on the Group's development/producing assets are conducted at each reporting date. The Group's development/producing assets were reviewed for indicators of impairment at 30 June 2019 and no indicators of impairment were identified. There have been no significant changes in market conditions or management's estimates and assumptions used in impairment testing at the December 2018 year end. Asset performance in 2019 has remained in line with or exceeded management's expectation.

At 30 June 2019, the decommissioning estimate for the Kraken producing asset has increased by US$24.7m. This reflects the conclusion of final development drilling during the period and an internal review of the latest cost estimates received from the operator. A decommissioning provision of US$3.8m was recognised for work performed on the Nova development project. The Catcher decommissioning estimate remained unchanged.

The decommissioning of the Group's development/producing assets is forecast to occur between 2026 and 2040.

RBL

The Group's RBL facility had cash drawings of US$60.0m at 30 June 2019.

Cairn signed an extension to its existing RBL facility with a syndicate of international banks in 2018, with a revised final maturity date of 20 December 2025. Under IFRS 9, the extension of the facility to December 2025 constitutes substantially different terms from the original and as such the financial liability relating to the original facility was extinguished on the date of the extension and replaced with a new liability based on the revised terms. The classification of amounts due in current and prior periods of less than and greater than one year reflects the impact of the extension to the facility. The maximum currently available to draw under the facility is US$488.0m.

EFF

As at 30 June 2019, US$40.3m (NOK 343.8m) was drawn under the Norwegian EFF. The maximum available amount is currently forecast to be US$60.0m (NOK 480.0m).

Interest on outstanding debt is charged at the appropriate NIBOR plus an applicable margin. Debt is repayable by the final maturity date, which is the earlier of 31 December 2022 or the date of receipt of the tax refund relating to exploration spend for 2021.

Section 4 - Income Statement Analysis

   4.1       Segmental Analysis 

Operating segments

The Group's portfolio of exploration and development/producing assets are managed through regional business units. Each business unit is headed by a regional director (a regional director may be responsible for more than one business unit) and the Board monitors the results of each segment separately for the purposes of making decisions about resource allocation and performance assessment.

In 2019, Cairn's business units have been revised to reflect changes in the portfolio of assets now held and therefore the Group's segmental analysis has been updated to align with the updated management structure and Board reporting. The International segment has been split into two separate units; 'East Atlantic' includes the Group's exploration assets in Ireland, Mauritania, and Cote D'Ivoire and 'LATAM' includes the Group's growing portfolio of Latin American assets in Mexico, Nicaragua and Suriname.

Remaining segments are unchanged. The Senegal business unit and segment is focussed on the development of the SNE discoveries, with approval of the development plan expected this year. The UK & Norway segment includes ongoing exploration programmes in the North Sea, Norwegian Sea and Barents Sea, the Norwegian Nova development project and UK Catcher and Kraken producing fields. The 'Other Cairn Energy Group' segment captures costs associated with the Group's head office and other corporate assets not allocable to a geographic segment.

The segment results for the six months ended 30 June 2019 are as follows:

   5.4     Contingent Liability - Indian Tax Assessment 

The formal hearings and submissions in respect of Cairn's claim under the UK-India Bilateral Investment Treaty concluded in 2018 and the arbitration panel is preparing its final award.

Whilst the panel had originally guided the parties that it expected to issue an award as expeditiously as possible, workload and the number of matters before the panel have meant that the timetable for issuing the award will be more protracted than originally anticipated and the award is therefore unlikely to be before late 2019.

Based on detailed legal advice, Cairn remains confident that it will be successful in this arbitration and accordingly no provision has been made for any of the tax or penalties assessed by the India Income Tax Department ('IITD').

The Group also has legal advice confirming that the maximum amount that could ultimately be recovered from Cairn by the IITD, in excess of the assets already seized, is limited to the value of CUHL's assets, including the remaining ordinary shares in Vedanta Limited.
