Chairman's Statement

Well placed to profit from market rebalancing

Energy markets have continued to prove volatile over the past year, with the oil price climbing 30 per cent. in the past six months ending in June, following a 38 per cent. decline over the prior six months. However, the initial signs of rebalancing are now emerging as producers in North America and elsewhere respond to dramatically lower energy prices and capital scarcity. As the Company's results today demonstrate, REL has established a highly resilient portfolio during a period of prolonged market volatility and is well placed to profit as the market recovers. 

During the first half of the year, REL committed an additional $142 million, which was allocated to existing portfolio companies Carrier II and Liberty II. The Carrier team, which has extensive experience operating in West Texas, opportunistically acquired interests in the prolific Sugarloaf Project in the Eagle Ford. The commitment to Liberty II, which is REL's earliest investment and focused on the Bakken and Powder River Basin, was increased to support investment in gas gathering and processing infrastructure, well completions and balance sheet strengthening.

Although REL's commitments exceed capital raised, the portfolio remains relatively young due to its strategy of gradually deploying capital across the cycle. Because of this "build-up" approach, where Riverstone controls the pace and deployment of capital, the Board is comfortable with current commitment levels. The history of Riverstone investments has shown that not all of the commitments made to portfolio companies are ultimately funded and in some cases are cancelled altogether. For example, as of 30 June 2016, Funds I through IV have only invested 87 per cent. of the total commitments to its portfolio companies. Also, REL's arrangements with Riverstone allow excess commitments to be amended by the Investment Manager with consideration from the Board.

REL's portfolio companies' management teams continued to make solid operational progress in the first half of the year. Meritage III's gathering and processing infrastructure became operational at the end of April, which will support CIOC as it continues to increase production from its extensive land position in Canada's Montney and Duvernay plays. Eagle II's initial well in the SCOOP produced strong results and the company is now pursuing a multi-well delineation drilling programme. While Origo and ILX III remain relatively early in their exploration programmes, they have already made five discoveries which are now being progressed toward development. Rock Oil and Three Rivers III continue to develop drilling programmes for their recently acquired properties. Elsewhere in the portfolio, Liberty II and Fieldwood took measures to optimise their capital structures, with Fieldwood agreeing a solution whereby it no longer faces borrowing base redeterminations until May 2018.

Valuations for some of the earlier investments made by REL continue to face challenges due to weak energy prices. However, the Company's build-up strategy, where capital is deployed gradually over time, has allowed several of its portfolio companies to benefit from industry distress, resulting in value accretion for Shareholders as evidenced by three of REL's four largest investments (CIOC, Rock Oil and Carrier II), being valued above cost. Throughout the portfolio, Riverstone continues to work with its portfolio companies' management teams to reduce operating expenses, hedge commodity price exposure where appropriate and maintain maximum capital flexibility to thrive in a variety of commodity price environments.

The recent announcement of the UK's exit from the EU has not impacted the portfolio, which is concentrated in North America.

At our AGM in May, I was elected non-executive Chairman of the Board following Sir Robert Wilson's retirement from industry. In addition, Jim Hackett stepped down to focus on his duties as an investment partner at Riverstone. While Jim's experience will be missed, Sir Robert has agreed to provide ongoing guidance as a senior adviser to REL. Furthermore, I am pleased to welcome Jeremy Thompson and Ken Ryan as additions to the Board. Jeremy brings extensive experience of the private equity and investment trust industry, while Ken has been deeply involved with the Company since its initial formation. I look forward to working with Jeremy, Ken and the rest of the Board to continue our work in growing the Company and creating Shareholder value.

Performance

REL made a profit of $25.23 million for the six months ended 30 June 2016, resulting in a NAV

per share at 30 June 2016 of $16.24, an increase of 2.5 per cent. from $15.85 and 1.8 per cent. from $15.95 at 31 March 2016 and 31 December 2015, respectively. The increase in NAV over the six months ended 30 June 2016 was primarily due to the increase in the fair market value of CIOC, Meritage III, Three Rivers III, Carrier II, Fieldwood and RCO, which offset a decline by Castex 2005. The depreciation of the British Pound Sterling has contributed to the NAV per share increasing by £1.42, or 13.1 per cent., when compared with the previous six months in Pounds Sterling terms. The $/£ exchange rate declined from 1.473 at 31 December 2015 to 1.326 at 30 June 2016. The Board is sensitive to the discount to NAV at which the REL shares currently trade and will continue to evaluate open market purchases as authorised by the Shareholders at the AGM.

As mentioned above, during the first half of the year, the Company made additional commitments of $100 million to Carrier II and $42 million to Liberty II to support these businesses as they continue to execute their strategies. As of 30 June 2016, REL, through the Partnership, had committed $1,722 million, or 127 per cent. of total capital available⁽¹⁾ to 16 investments. The Company's commitments are now split approximately evenly across four geographic areas: Western Canada, the Permian & Eagle Ford, Gulf of Mexico and niche strategies comprising credit, international opportunities and select US onshore basins. 

As of 30 June 2016, REL, through the Partnership, had invested $1,048 million, equating to 77 per cent. of total capital available⁽¹⁾. REL deployed $203 million in the first half of 2016, of which approximately two-thirds was directed towards investments in the prolific Permian and Eagle Ford basins. The largest investment during the period was $73 million, in which the Carrier II management team took advantage of volatile market conditions to acquire interests in the Sugarloaf Project in Karnes County, Texas in the Eagle Ford from two publicly-listed energy companies facing balance sheet constraints. The Carrier II team knows the asset well, which is operated by highly-regarded Marathon Oil and benefits from attractive breakeven oil price economics.

In the Permian Basin, Three Rivers III acquired approximately 36,000 net acres through two acquisitions offsetting their existing position in Culberson County, Texas. This resulted in an additional $45 million of investment by REL as the company continues its strategy of aggregating attractive asset packages with significant upside opportunities, as the team has successfully accomplished on two previous occasions for Riverstone. Since formation in April 2015, the company has established a position of approximately 55,000 net acres in the highly prospective Delaware Basin in the Permian.

In addition to acquisitions, REL invested approximately $39 million during the first half of 2016 to fund drilling programs for ILX III, Rock Oil, Eagle II and Origo. Riverstone Credit Opportunities invested $11 million during the first half of the year towards twelve additional investments. Meritage III invested an additional $7 million for construction of its gathering and processing infrastructure in Western Canada, which is now fully operational.

Subsequent to the period ending on 30 June 2016, REL announced its first exit, with the sale of Rock Oil for gross cash proceeds of approximately $237 million. This transaction results in excellent returns for REL, representing a Gross MOIC⁽²⁾ of 2.1x (Net MOIC of 1.6x) and a Gross IRR of 78 per cent. (Net IRR of 43 per cent.) on the Company's investment, through the Partnership, of $114 million, and affirms the strength of Riverstone's investment strategy even during periods of weak oil and gas prices.

In addition, REL announced an investment of up to $175 million in Centennial Resource Development LLC alongside other funds affiliated with Riverstone, including Fund VI and Silver Run Acquisition Corp., a Riverstone sponsored special purpose acquisition company. This investment will be led by Mark Papa, Riverstone partner and former chief executive of EOG Resources, and will further strengthen the portfolio's exposure to low-cost energy producers due to Centennial's significant resource potential in the oil-rich core of the Delaware Basin in the Permian.

REL's activity over the past six months demonstrates the strength of Riverstone's "build-up" approach. This has resulted in REL developing a high-quality portfolio with best-in-class management teams focused on highly attractive basins for hydrocarbon production. With 16 investment platforms, and over $250 million of un-invested capital, REL is uniquely positioned to continue to take advantage of opportunities and deliver value to Shareholders.

Investment Manager's Report

Well Positioned for Long Term Value Creation and Near Term Resiliency

It has been nearly two years since WTI traded over $100 per barrel in July 2014. While energy markets appear to have found the bottom of the cycle in the first half of 2016, with oil briefly trading below $30 per barrel in January, the price recovered to $50 per barrel in the second quarter as North American production responded to low prices and various supply disruptions shifted the market closer to balance. The signs of recovery, while encouraging, remain fragile, and we continue to position the portfolio to remain resilient to further market volatility.

Over the past 24 months, the energy market has gone through extreme turbulence, with oil prices declining by over 70 per cent. from peak to trough, resulting in significant financial stress and a dramatic decline in capital expenditure by industry participants. It is in times like these, that Riverstone's scale, experience and diversified investment approach serves to differentiate us from industry peers, particularly those who are less experienced in the energy sector. Riverstone has the benefit of a sixteen year history of private investing in energy, and its investment professionals have experience successfully investing in, and operating energy businesses through multiple commodity price cycles. The firm applies a disciplined approach to maintain maximum operational and capital flexibility under any commodity price environment.

One key element of Riverstone's strategy is the "build-up" approach, from which REL has particularly benefitted.  REL began committing capital and establishing investment platforms soon after its formation. However the pace of capital actually invested has been markedly slower with the most attractive opportunities emerging after the decline in commodity prices, resulting in the REL portfolio being invested at a weighted average oil price of approximately $51 per barrel. By establishing investment platforms early and backing experienced and focused management teams with significant line of equity commitments, REL was well positioned within key target basins to move quickly as attractive assets became available. This is particularly evident in Carrier II, Three Rivers III and Rock Oil, where the management teams had identified strategic assets in the Permian and Eagle Ford basins, and built up positions through a series of asset and corporate level acquisitions over a 12-24 month period. The REL portfolio is now 77 per cent. invested as of the end of June 2016.

As well as creating an opportunity to acquire assets at attractive valuations, the decline in oil prices has driven a general high-grading of the energy sector. With energy companies having less capital to invest, there has been an increasing drive for efficiency and lowering cost of production. This is particularly notable in the North American upstream sector, where well costs have declined and production rates increased, resulting in materially lower breakeven costs and significant divergence in the economics of different basins. Riverstone has always focused on high quality assets, and the REL portfolio is favorably exposed to the basins which we see has having the most attractive economics, in particular the Permian, Eagle Ford and Western Canada. In CIOC, well costs have declined by 50 per cent. since 2012, and earlier this year, the production rates from two of CIOC's wells were recorded as the two best performing wells in Alberta.

While we are confident that the long term outlook for the sector remains favorable, we expect the energy market to continue to be volatile in the short term given uncertainties over global economic growth and North American oil production. We continue to manage risk through diversifying across geographies and energy segments, focusing on build-up strategies, partnering with experienced, operationally-focused management teams, hedging cash flows from producing assets, using moderate levels of debt with flexible covenant structures, and maintaining sufficiently high levels of liquidity to take advantage of attractive acquisition opportunities. With 15 management teams and substantial positions in North America's most attractive basins, REL is well placed to reward patient investors.

Investment Strategy

The Investment Manager's objective is to achieve superior risk adjusted, after tax, returns by making privately negotiated control investments primarily in the exploration and production and midstream energy sectors, which is a significant component of virtually all major economies. Long-term market drivers of economic expansion, population growth, development of markets, deregulation, and privatisation allied to near-term commodity price volatility are expected to continue to create opportunities globally for Riverstone.

Key Drivers:

•    Capital constraints among companies with high levels of leverage;

•    Industry distress and pressures to rationalise assets;

•    Growing success rates of deepwater exploration and other technology-driven sources of reserves; and

•    Historical under-investment in energy infrastructure.

The Investment Manager, through its affiliates, has an outstanding track record of building businesses with exceptional management teams and of delivering consistently strong returns and significant outperformance against both crude oil and natural gas benchmarks. The Company aims to capitalise on the opportunities presented by Riverstone's pipeline of investments.

The Investment Manager utilises its extensive industry expertise and relationships to thoroughly evaluate investment opportunities and uses its significant experience in conducting due diligence, valuing assets and all other aspects of deal execution, including financial and legal structuring, accounting and compensation design. The Investment Manager also draws upon its extensive network of relationships with industry-focused professional advisory firms to assist with due diligence in other areas such as accounting, tax, legal, employee benefits, environmental, engineering and insurance.

Fieldwood

As of 30 June 2016, REL, through the Partnership, has invested $58 million of its $82 million commitment to Fieldwood. Riverstone formed Fieldwood in partnership with CEO Matt McCarroll and his team in December 2012 with a commitment from Fund V. Fieldwood has made two material acquisitions (from Apache and SandRidge), with three further bolt-on acquisitions, and now has an interest in approximately 500 leases covering over two million gross acres and over 1,000 wells in the Gulf of Mexico, making it the largest oil and gas producer in the Shallow Gulf of Mexico. During the first half of 2016, Fieldwood completed 34 recompletions and 30 workover projects, and materially reduced operating costs relative to 2015. During Q2 2016, REL, through the Partnership, along with Other Riverstone Funds, (collectively, the "Buyers"), completed open market purchases of 2^nd lien debt issued by Fieldwood. The Q2 2016 valuation of REL's interest in Fieldwood, through the Partnership, treats the 2^nd lien debt owned by the Buyers as though it were cancelled. Fieldwood also eliminated any borrowing base re-determinations until May 2018.

As of 30 June 2016, REL's interest in Fieldwood, through the Partnership, was valued at 1.0x Gross MOIC⁽¹⁾ or $58 million (Realised $1 million, Unrealised $57 million).

Origo is a Norway-based oil and gas company focused on exploration on the Norwegian and UK continental shelves.  Since inception, Origo has reviewed over 250 potential farm-in opportunities, and completed seven farm-in transactions, and made three discoveries from six exploration wells drilled.

As of 30 June 2016, REL's interest in Origo, through the Partnership, was valued at 1.0x Gross MOIC⁽¹⁾ or $7 million.

Sierra

As of 30 June 2016, REL, through the Partnership, has invested $3 million of its $75 million commitment to Sierra. Sierra is an independent Mexican energy company established to pursue select upstream and midstream opportunities in Mexico. In July 2015, Sierra secured two oil and gas exploration blocks in Mexico's initial shallow Gulf of Mexico tender. Sierra and its partners are currently undertaking subsurface assessments on these blocks ahead of initiating a drilling campaign. The company is also advancing several midstream development opportunities.

As of 30 June 2016, REL's interest in Sierra, through the Partnership, was valued at 1.0x Gross MOIC⁽¹⁾ or $3 million.

CanEra III

As of 30 June 2016, REL, through the Partnership, has invested $1 million of its $60 million commitment to CanEra III.

As of 30 June 2016, REL's interest in CanEra III, through the Partnership, was valued at 1.0x Gross MOIC⁽¹⁾ or $1 million.

Going Concern

Of the $11.5 million of cash retained by the Company in the IPO and Placing and Open Offer, and the $5.5 million distribution from the Partnership in Q1 2016, $5.5 million remains at 30 June 2016. This amount is adequate to meet the Company's liabilities as they fall due over the next twelve months. In accordance with section 4.1(a) of the Partnership Agreement, the Company is expected to receive another distribution from the Partnership in the event it requires additional funds.

As at 30 June 2016, the Partnership had $264 million of uninvested funds held as cash and money market fixed deposits (31 December 2015: $555 million), and has no material going concern risk. Although the Company's commitments, through the Partnership, exceed its available liquid resources, it is not expected that all commitments will be drawn due to a variety of factors, such as the portfolio company being sold earlier than anticipated or the targeted investment opportunity changing or disappearing. In addition, the board of each underlying portfolio company, more often than not controlled by Riverstone, has discretion over whether or not that capital is ultimately invested. Moreover, REL's arrangements with Riverstone allow excess commitments to be amended by the Investment Manager with consideration from the Board. In light of the above, the Directors are satisfied that it is appropriate to adopt the going concern basis in preparing the interim condensed financial statements.

Principal Risks and Uncertainties

The Company's assets consist of investments, through the Partnership, within the global energy industry, with a particular focus on opportunities in the global exploration and production and midstream energy sectors. Its principal risks are therefore related to market conditions in the energy sector in general, but also the particular circumstance of the businesses in which it is invested through the Partnership. The Investment Manager, through the Partnership, seeks to mitigate these risks through active asset management initiatives and carrying out due diligence work on potential targets before entering into any investments.

The key areas of risk faced by the Company are the following: 1) concentration risk from investing only in the global energy sector, 2) Ordinary Shares trading at a discount to NAV per Share and 3) inherent risks associated with the exploration and production and midstream energy subsectors.

The principal risks and uncertainties of REL were identified in further detail in the 2015 Annual Report and Financial Statements. There have been no changes to REL's principal risks and uncertainties in the six-month period to 30 June 2016 and no changes are anticipated in the second half of the year.

Subsequent Events and Outlook

In July 2016, REL, through the Partnership, announced an investment in Centennial Resource Development LLC through the purchase of shares in NASDAQ-listed Silver Run Acquisition Corporation. Silver Run, subject to certain conditions including approval of the Silver Run stockholders, will acquire a controlling interest in Centennial from NGP Energy Capital. Centennial is an exploration and production company focused on the acquisition and development of oil and liquids-rich natural gas resources in the Permian Delaware Basin, West Texas. The investment by REL, through the Partnership, is expected to comprise up to $175 million.

In August 2016, REL announced the sale of Rock Oil to SM Energy Company, a US-based E&P company. Under the terms of the transaction, REL, through the Partnership, will realise gross cash proceeds of approximately $237 million, representing a Gross MOIC⁽¹⁾ of 2.1x (Net MOIC of 1.6x) on the $114 million investment and a Gross IRR of 78 per cent. (Net IRR of 43 per cent.). This will result in a gross realised gain of $123 million and an uplift of $84 million or 55 per cent. above its fair value of $152 million as at 30 June 2016. The Company's gross profit, through the Partnership, will be subject to taxes and a performance fee, resulting in a net uplift to the Company's NAV at 30 June 2016 of approximately $44 million⁽²⁾. The closing of the sale is expected to occur in early October 2016 and is subject to customary closing conditions.

Also in August 2016, REL agreed to transfer half of its investment to date and unfunded commitment in Sierra, $1.3 million and $36.2 million, respectively, to a separate investment vehicle managed by Riverstone and funded primarily by Mexican pension funds. This transfer is in line with REL's stated strategy of periodically reviewing its unfunded commitment levels.

Independent Review Report to Riverstone Energy Limited

We have been engaged by the Company to review the condensed set of financial statements in the Interim Financial Report for the six months ended 30 June 2016 which comprises the Statement of Financial Position, the Statement of Comprehensive Income, the Statement of Changes in Equity, the Statement of Cash Flows and the related Notes 1 to 11. We have read the other information contained in the Interim Financial Report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed set of financial statements.

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

Directors' Responsibilities

The Interim Financial Report is the responsibility of, and has been approved by, the Directors. The Directors are responsible for preparing the Interim Financial Report in accordance with the Disclosure and Transparency Rules of the United Kingdom's Financial Conduct Authority.

As disclosed in Note 2, the Financial Statements of the Company are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of financial statements included in this Interim Financial Report has been prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting", as adopted by the European Union.

Our Responsibility

Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the Interim Financial Report based on our review.

Scope of Review

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

Conclusion

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

Notes to the UNAUDITED Interim Condensed Financial Statements

For the six months ended 30 June 2016

1.    General information

Riverstone Energy Limited is a company limited by shares, which was incorporated on 23 May 2013 in Guernsey with an unlimited life and registered with the GFSC as a Registered Closed-ended Collective Investment Scheme pursuant to the POI Law. It has been listed on the London Stock Exchange since 29 October 2013. The registered office of the Company is Heritage Hall, PO Box 225, Le Marchant Street, St Peter Port, Guernsey, GY1 4HY, Channel Islands.

The Company makes its investments through the Partnership, a Cayman Islands registered exempted limited partnership, in which the Company is the sole limited partner. The principal place of business of the Partnership is the Cayman Islands. Both the Company and the Partnership are subject to the Investment Management Agreement with the Investment Manager, a company registered in the Cayman Islands.

The Partnership invests alongside Private Riverstone Funds in all Qualifying Investments in which the Private Riverstone Funds participate. These funds are managed and advised by affiliates of the Investment Manager. Further detail of these investments is provided in the Investment Manager's Report.

2.    Accounting policies

Basis of preparation

The Financial Statements for the year ended 31 December 2015 were prepared in accordance with IFRS.

These interim condensed financial statements have been prepared in accordance with International Accounting Standard 34 "Interim Financial Reporting". They do not contain all the information and disclosures presented in the Financial Statements and should be read in conjunction with the Financial Statements for the year ended 31 December 2015.

The same accounting policies and methods of computation have been followed in the preparation of these interim condensed financial statements as were followed in the Financial Statements for the year ended 31 December 2015.

These interim condensed financial statements are presented in U.S. dollars and are rounded to the nearest $'000, unless otherwise indicated.

The Company's results do not vary significantly during reporting periods as a result of seasonal activity.

3.    Critical accounting judgement and estimation uncertainty

The estimates and judgements made by management are consistent with those made in the Financial Statements for the year ended 31 December 2015.

4.    Taxation

The taxation basis of the Company remains consistent with that disclosed in the Financial Statements for the year ended 31 December 2015.

The Company has made an election to, and currently expects to conduct its activities so as to be treated as a partnership for U.S. federal income tax purposes. Therefore, the Company expects that it generally will not be liable for U.S. federal income taxes. Instead, each of the Company's Shareholders who are liable to U.S. taxes will take into account its respective share of the Company's items of income, gain, loss and deduction in computing its U.S. federal income tax liability as if such Shareholder had earned such income directly, even if no cash distributions are made to the Shareholder. Neither the Company nor the Partnership are subject to Guernsey or Cayman Islands income taxes.

Local taxes may apply at the jurisdictional level on profits arising in operating entity investments. Further withholding taxes may apply on distributions from such operating entity investments. Based upon the current commitments and investments in Liberty II, Eagle II, Rock Oil, Fieldwood, Castex 2014, Castex 2005, Three Rivers III, Carrier II and ILX III, the future U.S. tax liability on profits is expected to be in the range of 35 to 41.5 per cent.

5.    Fair value

IFRS 13 'Fair Value Measurement' requires disclosure of fair value measurement by level. The level in the fair value hierarchy within which the financial assets or financial liabilities are categorised is determined on the basis of the lowest level input that is significant to the fair value measurement, adjusted if necessary.

Financial assets and financial liabilities are classified in their entirety into only one of the three levels:

•    Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities;

•    Level 2 - inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. as prices) or indirectly (i.e. derived from prices);

•    Level 3 - inputs for the assets or liabilities that are not based on observable market data (unobservable inputs).

The Company's only financial instrument carried at fair value is its investment in the Partnership which has been classified within Level 3 as it is derived using unobservable inputs. Amounts classified under Level 3 for the period ended 30 June 2016 were $1,367 million (31 December 2015: $1,345 million).

The fair value of all other financial instruments approximates their carrying value.

Transfers during the period

There have been no transfers between levels during the period ended 30 June 2016 and the year ended 31 December 2015. Any transfers between the levels will be accounted for on the last day of each financial period. Due to the nature of the investment, it is always expected to be classified under Level 3.

Valuation methodology and process

The same valuation methodology and process was deployed in June 2016 and December 2015.

For the period ended 30 June 2016, the valuations of the Company's investments, through the Partnership, are detailed in the Investment Manager's Report.

Quantitative information about Level 3 fair value measurements as at 30 June 2016

The table summarises the most significant valuation techniques and unobservable inputs used in those techniques together with relevant ranges and averages. The Board considers the inputs to be within a reasonable expected range based on their understanding of market transactions. This is not intended to imply that the likelihood of change or that possible changes in value would be restricted to this range.

Quantitative information about Level 3 fair value measurements as at 31 December 2015

^(a) Calculated based on fair values

^(b) Each of the Partnership's investments are valued using one or more of the techniques which utilise one or more of the unobservable inputs, so the amounts in the "# of investments" column will not aggregate to the total number of the Partnership's investments

The significant unobservable inputs used in the fair value measurement of the Partnership's investments at 30 June 2016 include the oil and gas price curves, multiples derived from 1P and 2P reserves, barrels of energy production per day, and valuations implied by the last round of financing. A 10 per cent. change in the oil and gas curves, multiples derived from 1P reserves and barrels of energy production per day taken together could result in a respective decrease and increase in the fair value measurement of the Partnership's investments of approximately $264 million, or 20 per cent. of the Company's NAV at 30 June 2016.

The Board reviews and considers the fair value of the Partnership's investments arrived at by the Investment Manager before incorporating into the fair value of the Partnership. The variety of valuation bases adopted, quality of management information provided by the underlying investee companies and the lack of liquid markets for the investments mean that there are inherent difficulties in determining the fair value of these investments that cannot be eliminated. Therefore the amounts realised on the sale of investments may differ from the fair values reflected in these interim condensed financial statements and the differences may be significant.

The Board approves the valuations performed by the Investment Manager and monitors the range of reasonably possible changes in significant observable inputs on a quarterly basis, as well as when needed due to changes in market conditions.

6.    Investment at fair value through profit or loss

The movement in fair value is derived from the fair value movements in the underlying investments held by the Partnership, net of income and expenses of the Partnership and its related Investment Undertakings, including any Performance Allocation and applicable taxes.

Summary financial information for the Partnership

⁽¹⁾ Investments at fair value after deferred tax on investment of $Nil (31 December 2015: $Nil)

Summary Income Statement

⁽¹⁾ Unrealised gain on investments after deferred tax on investment of $Nil (30 June 2015: $3,132,692)

7.    Contingent liabilities

The Company's existing contingent liabilities in relation to the formation and initial expenses was $4.0 million as at 30 June 2016 (31 December 2015: $10.0 million).

8.    Related party transactions

Parties are considered to be related if one party has the ability to control the other party or exercise significant influence over the party in making financial or operational decisions.

Directors

The Company has eight non-executive Directors (31 December 2015: eight).

Mr Ken Ryan is a senior executive of Riverstone and was appointed as a non-executive Director on 19 May 2016. As a non-independent Director, Mr Ryan has chosen not to be remunerated by the Company for his services.

Mr Jeremy Thompson was appointed as a non-executive Independent Director on 19 May 2016 and is entitled to annual remuneration of $88,000 (£60,000).

Directors' fees and expenses for the period ended 30 June 2016 amounted to $383,791 (30 June 2015: $495,215), none of which was outstanding at period/year end (31 December 2015: none).

Partnership

In accordance with section 4.1(a) of the Partnership Agreement, the Company received a distribution from the Partnership of $5.5 million to meet the Company's forecasted liabilities over the course of the next twelve months.

Investment Manager

For the provision of services under the Investment Management Agreement, the Investment Manager is paid in cash out of the assets of the Partnership an annual Management Fee equal to 1.5 per cent. per annum of the Company's Net Asset Value. The fee is payable quarterly in arrears and each payment is calculated using the quarterly Net Asset Value as at the relevant quarter end as further outlined on page 72 in the Financial Statements to 31 December 2015. During the period to 30 June 2016, the Partnership incurred Management Fees of $10,167,646 (30 June 2015: $8,159,471) of which $5,146,405 remained outstanding as at the period/year end (31 December 2015: $5,051,958). No management fee is paid by the Company.  

General Partner

The General Partner makes all management decisions, other than investment management decisions, in relation to the Partnership and controls all other actions by the Partnership and is entitled to receive a Performance Allocation, calculated and payable at the underlying investment undertaking level, equal to 20 per cent. of the realised profits (if any) on the sale of any underlying asset of the Company. During the period to 30 June 2016, the General Partner was entitled to receive a Performance Allocation of $10,227,726 (30 June 2015: $4,491,001) of which $36,386,998 remained outstanding as at the period/year end (31 December 2015: $26,159,272). No Performance Allocation is paid by the Company.   

The General Partner is entitled to receive its Performance Allocation in cash, all of which, after tax, Riverstone, through its affiliate RELCP, intends to reinvest in Ordinary Shares of the Company on the terms summarised in Part I and Part VIII of the IPO Prospectus.

Cornerstone Investors

Each of the Cornerstone Investors has acquired an indirect economic interest in each of the General Partner and the Investment Manager depending on the size of their commitment and the total issue size, up to an aggregate maximum indirect economic interest of 20 per cent. in each, for nominal consideration. These interests entitle the Cornerstone Investors to participate in the economic returns generated by the General Partner, including from the Performance Allocation, and the Investment Manager, which receives the Management Fee.

9.    Segmental reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Board of Directors, as a whole. The key measure of performance used by the Board to assess the Company's performance and to allocate resources is the total return on the Company's Net Asset Value, as calculated under IFRS, and therefore no reconciliation is required between the measure of profit or loss used by the Board and that contained in the Financial Statements and Interim Financial Report.

For management purposes, the Company is organised into one main operating segment, which invests in one limited partnership.

All of the Company's income is derived from within Guernsey and the Cayman Islands.

All of the Company's non-current assets are located in the Cayman Islands.

Due to the Company's nature, it has no customers.

10.  Earnings per Share and Net Asset Value per Share

Earnings per Share

The Earnings per Share is based on the profit or loss of the Company for the period and on the weighted average number of Shares the Company had in issue for the period.

There are no dilutive Shares in issue as at 30 June 2016 (30 June 2015: none).

Net Asset Value per Share

⁽¹⁾ Based on exchange rate of 1.326 $/£ at 30 June 2016 (1.473 $/£ at 31 December 2015 and 1.573 $/£ at 30 June 2015)

The Net Asset Value per Share is arrived at by dividing the net assets as at the date of the Statement of Financial Position by the number of Ordinary Shares in issue at that date.

11.  Subsequent events

In July 2016, REL, through the Partnership, announced an investment in Centennial Resource Development LLC through the purchase of shares in NASDAQ-listed Silver Run Acquisition Corporation. Silver Run, subject to certain conditions including approval of the Silver Run stockholders, will acquire a controlling interest in Centennial from NGP Energy Capital. Centennial is an exploration and production company focused on the acquisition and development of oil and liquids-rich natural gas resources in the Permian Delaware Basin, West Texas. The investment by REL, through the Partnership, is expected to comprise up to $175 million.

In August 2016, REL announced the sale of Rock Oil to SM Energy Company, a US-based E&P company. Under the terms of the transaction, REL, through the Partnership, will realise gross cash proceeds of approximately $237 million, representing a Gross MOIC⁽²⁾ of 2.1x (Net MOIC of 1.6x) on the $114 million investment and a Gross IRR of 78 per cent. (Net IRR of 43 per cent.). This will result in a gross realised gain of $123 million and an uplift of $84 million or 55 per cent. above its fair value of $152 million as at 30 June 2016. The Company's gross profit, through the Partnership, will be subject to taxes and a performance fee, resulting in a net uplift to the Company's NAV at 30 June 2016 of approximately $44 million⁽³⁾. The closing of the sale is expected to occur in early October 2016 and is subject to customary closing conditions.

Also in August 2016, REL agreed to transfer half of its investment to date and unfunded commitment in Sierra, $1.3 million and $36.2 million, respectively, to a separate investment vehicle managed by Riverstone and funded primarily by Mexican pension funds. This transfer is in line with REL's stated strategy of periodically reviewing its unfunded commitment levels.

⁽²⁾ Gross MOIC is Gross Multiple of Invested Capital before transaction costs, taxes, carried interest on gross profit, management fees and other expenses.

⁽³⁾ Amount is subject to additional taxes up to approximately $10 million
