Chairman's Statement

Low-Cost Positioning Provides Resilience and Growth

At the beginning of this year, we noted the rebalancing process in the oil market as both North American producers and OPEC restrained production, helping drive oil prices above $55 per barrel. However, this proved only temporary as production growth in North America resumed in response to higher prices, and shale producers continued to reduce costs through innovation and productivity enhancements. The resilience of shale producers has surprised industry once again, resulting in lower prices as the market continues to seek equilibrium.

This resilience is evident within the REL portfolio where companies such as CIOC and Centennial continue to experience improvements in well costs and productivity, with CIOC having reduced drilling and completion costs by more than half since 2012, and Centennial under the leadership of Mark Papa forecasting oil production growth by a factor of ten through 2020. Elsewhere, companies such as Liberty II and Eagle II are seeing the benefits of early entry into plays such as the Powder River Basin and SCOOP, where operators can drive productivity gains.   

The portfolio is now largely invested, having deployed 91 per cent. of net capital available. By establishing investment platforms with best-in-class management teams and a strong capital position, REL has been able to significantly expand its presence throughout the cycle to establish meaningful investments in some of North America's most attractive basins. For example, approximately two-thirds of the portfolio is invested in the Permian, Eagle Ford and Western Canada. This positioning, along with Riverstone's emphasis on conservative capital structures, has resulted in a portfolio which is well placed to withstand short term fluctuations in commodity prices.

With REL approaching its fourth anniversary, several of the investments are reaching the stage where they could become attractive candidates for acquisition or a public market exit over the next 12-18 months. For example, investments with vast and contiguous acreage packages are likely to be valued by both financial investors and trade buyers seeking to establish a meaningful presence in an attractive basin. The North American energy sector, characterised by low breakeven costs, short cycle times and high asset liquidity remains an attractive investment prospect, and we believe that well managed companies that are exposed to these resources and have strong balance sheets will continue to offer investors the best opportunities for capital growth in the energy sector.

Performance

REL ended 30 June 2017 with an NAV of $19.74 per share. This equates to a decrease of 36 cents (1.8 per cent.), when compared to NAV per share at 31 December 2016. The NAV per share decrease was larger on a  Sterling basis, at 6.9 per cent., due to the strengthening of Pound Sterling over the period.

The primary driver of the decline in NAV was REL's second largest investment, Centennial, which is publicly traded and saw its share price decline from $19.72 at the end of December to $15.82 at 30 June 2017 as market sentiment for oil producers weakened. Fieldwood and Carrier II also suffered valuation declines as the lower oil price weighed on trading comparables and asset valuations, and Fieldwood was impacted by a number of short term production disruptions. However, these were largely offset by strong performance at other portfolio companies, most notably Three Rivers III, which grew from a Gross MOIC of 2.5x to 3.0x as acreage prices continued to appreciate in the Delaware Basin. Liberty II and Meritage III also experienced significant increases due to the emerging Powder River Basin position and ongoing operational successes, respectively.

This has meant that the NAV has held relatively steady against the backdrop of a 14 per cent. decline in West Texas Intermediate oil price benchmark during the first half of the year, and negative sentiment impacting energy shares, with the S&P Oil & Gas E&P Index and FTSE 350 Oil & Gas Producers Index declining by 23 per cent. and 12 per cent., respectively. While REL shares experienced a 6.6 per cent. decline, they outperformed the above indices by 16 per cent. and 5 per cent., respectively. Shares closed the quarter at a 17 per cent. discount to NAV. The Board continues to consider options to narrow the discount, including open market purchases as authorised by the Shareholders at the AGM.

While REL did not make any new commitments during the period, the Company invested $142 million in existing portfolio companies for the exercise of warrants in CIOC as well as drilling and other operational expenses elsewhere in the portfolio. CIOC received total warrant proceeds of C$180 million (of which C$84 million came from REL), which will allow the company to accelerate its drilling programme and fund opportunistic land acquisitions. The second largest investment during the period was made to ILX III for $26 million to fund the drilling of three prospects in the Gulf of Mexico. Other investments were made to Liberty II and Three Rivers III, both of which have been actively drilling in the first half of this year. In total, REL has net invested capital of $1,314 million, equating to 91 per cent. of net capital available at the end of June 2017.

We believe it is appropriate for the Company to maintain a level of over-commitment, in order to optimise the level of invested capital. Commitments are structured to maximise flexibility, and portfolio companies are often fully or partially monetised prior to drawing the full committed amounts. In addition, the Board continually evaluates commitments given the evolving opportunity set in the energy sector. In the first half of this year, we withdrew $116 million of commitments to Origo and CanEra III. In both instances, we no longer felt there were attractive opportunities to deploy capital given the market for undeveloped discoveries in the North Sea and conventional oil and gas opportunities in Western Canada, respectively. While we are disappointed these investments did not meet our expectations at the time the commitments were made, we were able to limit capital exposure to $11 million, highlighting the flexibility of Riverstone's investment strategy and build-up approach. As of 30 June 2017, REL has commitments of $1,718 million to 14 current investments, equating to 119 per cent. of net capital available⁽¹⁾. REL, including the Partnership, had a cash balance of over $124 million at this date.

Our investments continued to make strong operational progress in the first half of the year. Meritage III, which provides a range of midstream services in Western Canada, has signed additional offtake agreements with CIOC and third parties, which will result in additional volumes to support the construction of a second gas gathering and processing facility. Elsewhere in the Montney, CNOR continues to develop its Pipestone position, where it has accumulated nearly 25,000 acres and completed four delineation wells. In the Delaware Basin of the Permian, Three Rivers III has now drilled five wells, which is helping prove out its 60,000 net acre position. ILX III made two additional discoveries during the period and has achieved a 73 per cent. success rate on exploration drilling to date. 

Subsequent to the period end, Sierra announced a historic oil discovery in the shallow waters of the Gulf of Mexico. The Zama 1 well, located in Mexico's Block 7, confirmed the presence of a light oil resource estimated to be in the range 1.4 billion and 2.0 billion barrels of oil in place. Ongoing studies will allow estimation of likely recovery factors and other important parameters, but it is already clear that Zama will rank as one of the largest shallow water discoveries anywhere in the world over the last five years. Although the discovery remains at an early stage, the Board is pleased to see encouraging results from Riverstone's strategy of being an early mover as the Mexican government embarked on its historic energy market reform. We remain excited about future opportunities for REL in Mexico through Sierra's four additional upstream blocks it has secured, as well as Fieldwood, which is awaiting results from two offshore wells which it spud in the first half of the year.

Oil prices could continue to prove volatile over the next several months as the market tests the ability of shale producers to respond to price signals by moderating drilling activity and capital expenditure budgets. In addition, the market will be carefully observing any rhetoric from OPEC regarding future production cuts, given that Libya, Nigeria and Iraq have increased volumes in recent months. While future cohesion among OPEC remains uncertain, oil demand growth continues to be robust, helping normalise the inventories which have been built-up over the cycle. Finally, geopolitical risks and sanctions against key producers could always surprise the market.

Throughout a period of protracted commodity price volatility, REL has benefited from Riverstone's strategy of deploying capital towards basins with low costs of production, prudent balance sheet management and an unwavering focus on operational excellence. While the portfolio would be impacted by a sharp decline in weaker energy prices, we are confident that the quality of the management teams and their assets will continue to prove resilient throughout the cycle. With 14 active investments across E&P and midstream in North America, REL offers investors a unique opportunity to invest in the most dynamic area of the energy market, and we believe those with a long-term outlook will be handsomely rewarded.

Investment Manager's Report

North American Energy Producers Prove their Resilience

The oil market rebalancing, which we saw earlier in the year, has paused as drillers across North America responded to temporarily higher oil prices. This, along with plentiful access to equity and credit, has resulted in oil production once again increasing in North America. Throughout the cycle, we remain focussed on ensuring a resilient portfolio which is positioned in the most competitive basins to withstand volatility and deliver upside as the rebalancing process resumes.

Drilling activity in the United States, measured by oil rigs, remains at less than half of its peak in late 2014. Nevertheless, oil production continues to expand, approaching record levels, with 9.4 million barrels per day at the end of June. Several forces have contributed to this growth. Producers continue to be selective in where they choose to drill, focusing primarily on the most productive locations which allow them to extract hydrocarbons at the lowest cost. For this reason, areas such as the Permian Basin of Texas with its multiple layers of oil-bearing shale are seeing significantly increased rig activity and growing production, while activity in higher-cost regions remains muted. Second, the "revolution" of hydraulic fracturing continues to evolve as engineers increase well productivity through longer laterals, higher frac stages, tighter cluster spacing and more intense fracs. This has resulted in higher well productivity and lower per barrel well costs, and is further supported by cyclical declines in supply chain service costs. Finally, strong capital availability, particularly when oil traded above $50 per barrel earlier in the year, has fueled drilling activity by allowing producers to access capital markets on relatively advantageous terms.  

Energy prices are likely to continue to be volatile as the market, in search of equilibrium, parses through the abundance of data generated by both North American producers and OPEC. We continue to monitor a number of drivers, in addition to commodity prices, which could impact production growth going forward. These include cost inflation as producers pour into select geographies thereby increasing demand for water, sand, frac crews and other services and also the exploitation of core acreage within a basin, forcing drillers into fringe  acreage following several years of "high-grading." As described above, credit conditions play a key role in enabling or curbing capital expenditure plans. With many producers free cashflow negative across the industry, a tightening of capital availability would significantly rein-in drilling activity. This could have a pronounced impact on supply due to shale's larger share of North American production, which experiences sharp decline rates relative to conventional wells, and therefore requires continued expenditure to maintain production levels.

In this dynamic environment, Riverstone is able to leverage our extensive expertise across the energy value chain and capital structure to identify profitable opportunities for REL and its investors. There are several examples of this within the REL portfolio, including the formation of RCO to take advantage of energy credit markets and Sierra, which Riverstone formed as Mexico's first private oil and gas company ahead of the country's historic energy sector reform. Elsewhere, we have worked to establish platforms in emerging, low-cost basins through Three Rivers III, which was an early mover into the Delaware Basin of the Permian, and our investment in CIOC, which controls a vast acreage position in the Montney and Duvernay shale plays of Western Canada. By establishing investment platforms early in the cycle, and backing experienced and focussed management teams with significant lines of equity commitments, REL has been well positioned to move quickly as attractive assets became available.

The "build-up" approach remains a key component of Riverstone's investment strategy. Riverstone and its investment professionals have many years of experience successfully investing in, and operating, energy businesses through multiple commodity price cycles. The firm applies a disciplined approach to maintain maximum operational and financial flexibility through any commodity price environment. While energy prices have been particularly volatile since REL's IPO in October 2013, when prices hovered around $100 per barrel, Riverstone's investment strategy has helped mitigate the impact of commodity price volatility on portfolio valuation. As a result, the REL portfolio has deployed capital at a weighted average oil price of approximately $54 per barrel. Over the same time period, NAV per share has increased by 23 per cent. on a USD basis and the share price by 26 per cent. on a Pounds Sterling basis, compared with a negative 52 per cent. total shareholder return for the U.S. E&P Index.

While the energy market remains volatile, we remain confident in our ability to deliver strong returns to shareholders given the quality of REL's investments and Riverstone's focussed strategy. We continue to manage risk through diversifying across basins and energy segments, while consistently focusing on build-up strategies, partnering with experienced, operationally-focussed 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 14 active investments across North America's most attractive basins, REL is well positioned for continued value growth.

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 E&P 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;

•    Increases in ability to extract hydrocarbons from oil and gas-rich shale formations; and

•    Historical under-investment in energy infrastructure.

The Investment Manager, through its affiliates, has a strong track record of building businesses with management teams and of delivering consistently attractive 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, having made over 130 investments globally in the energy sector since being founded in 2000, 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-focussed professional advisory firms to assist with due diligence in other areas such as accounting, tax, legal, employee benefits, environmental, engineering and insurance.

^([1]) Realised capital is total gross proceeds realised on invested capital. Of the $323 million of capital realised to date, $199 million is the return of the cost basis, and the remainder is profit

⁽²⁾ Net invested capital is total invested capital less cost basis of the realised capital

(³⁾ Gross MOIC is Multiple of Invested Capital. Gross Unrealised Value and Gross MOIC are before transaction costs, taxes (approximately 35 to 41.5 per cent. of U.S. sourced taxable income) and 20 per cent. carried interest on gross profits (without a hurdle rate). Since there is no netting of losses against gains, the effective carried interest rate on the portfolio as a whole will be greater than 20 per cent. In addition, there is a management fee of 1.5 per cent. of net assets per annum and other expenses. Given these costs, fees and expenses are in aggregate expected to be considerable, Total Net Value and Net MOIC will be materially less than Gross Unrealised Value and Gross MOIC.  Local taxes, primarily on US assets, 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

Investment Portfolio Summary

As of 30 June 2017, REL's portfolio comprised fourteen active investments including twelve E&P investments, one midstream investment and one credit investment.

CIOC

As of 30 June 2017, REL, through the Partnership, has invested $295 million of its $307 million commitment to CIOC. CIOC is a private E&P company focussed on liquids-rich unconventional resources in Western Canada. Since its establishment in 2010, CIOC has aggregated one of the largest and most advantaged land positions in the emerging Montney and Duvernay formations of Western Canada's Deep Basin. The company controls and operates 100 per cent. of this asset base, which comprises over 400,000 net acres in the Montney and Duvernay. CIOC has more than quadrupled production to over 16,000 boepd since time of entry.

In the first half of 2017, REL and other investors exercised warrants which resulted in C$180 million of proceeds to CIOC and will be used to fund drilling for continued development and delineation of its asset base.

As of 30 June 2017, REL's interest in CIOC, through the Partnership, was valued at 1.8x Gross MOIC⁽¹⁾ or $533 million (Realised $23 million, Unrealised $510 million). While the headline multiple on REL's investment in CIOC decreased over the period due to the $64 million warrant exercise investment being valued at cost, the value of the company remains unchanged.

Centennial

As of 30 June 2017, REL, through the Partnership, has invested in full its $268 million commitment to Centennial. Centennial is an E&P company focussed on the acquisition and development of oil and liquids-rich natural gas resources in the Permian Delaware Basin, West Texas. The company, led by Mark Papa, former chief executive of EOG Resources, Inc., has rapidly aggregated an 88,000 net acre position in the Delaware Basin of the Permian with no debt on the balance sheet at the end of the first quarter. The company's development plan envisages growing oil production from approximately 5,700 boepd in 2016 to 60,000 boepd in 2020.

REL, through the Partnership, owns approximately 23.9 million shares which are publicly traded (NASDAQ:CDEV), at a weighted average share price of $11.21. REL, through the Partnership, has financed $93 million of its investment through a bank loan secured by REL's investment in Centennial. In addition, REL has interests in approximately $2 million of sponsor warrants.

As of 30 June 2017, REL's interest in Centennial, through the Partnership, was valued at 1.4x Gross MOIC⁽¹⁾ or $380 million. The valuation for Centennial decreased over the period, reflecting the mark-to-market value of REL's shareholding.

Three Rivers III

As of 30 June 2017, REL, through the Partnership, has invested $86 million of its $167 million commitment to Three Rivers III. Similar to Riverstone's two prior successful partnerships with this management team, Three Rivers III focuses on oil and gas acquisition and development opportunities in the Permian Basin. Through a series of acquisitions, Three Rivers III has built a position of 60,000 net acres in the Permian Delaware basin, primarily in Culberson & Reeves counties. The company drilled five wells in the first half of 2017 as the team continues to delineate its position and is producing approximately 3,900 boepd.

As of 30 June 2017, REL's interest in Three Rivers III, through the Partnership, was valued at 3.0x Gross MOIC⁽¹⁾ or $259 million. The valuation for Three Rivers III increased over the period, reflecting increased acreage multiples in the Permian.

Carrier II

As of 30 June 2017, REL, through the Partnership, has invested $110 million of its $133 million commitment to Carrier II. Carrier II is focussed on the acquisition and exploitation of upstream oil and gas assets by partnering with select operators that are developing both unconventional and conventional reservoirs in North America. Shortly after its establishment in May 2015, Carrier II entered into a joint venture agreement with a highly experienced operator group made up of Henry Resources and PT Petroleum targeting 19,131 net acres for development in the southern Midland Basin. Subsequently through three separate acquisitions the company has acquired 3,489 net acres in Karnes County in the Eagle Ford basin, targeting the Sugarloaf Project and the Chisholm Project, both operated by Marathon Oil Corp. As of end of the Period, Carrier II was producing over 8,000 boepd net.

As of 30 June 2017, REL's interest in Carrier II, through the Partnership, was valued at 1.2x Gross MOIC⁽¹⁾ or $131 million. The valuation for Carrier II decreased over the period, reflecting a lower net asset value largely driven by weaker commodity prices.

Liberty II

As of 30 June 2017, REL, through the Partnership, has invested $137 million of its $142 million commitment to Liberty II. As of December 2016, Liberty II had established a c. 62,000 net acre position in the Williston and Powder River Basins through a series of acquisitions, which benefit from Liberty II's sophisticated and proprietary well completion technology. In the first half of 2017, Liberty II acquired an additional 34,000 net acres in Bakken, bringing its total position to 96,000 net acres. Liberty has an inventory of over 240 gross drilling locations, and is currently producing approximately 8,000 boepd.

As of 30 June 2017, REL's interest in Liberty II, through the Partnership, was valued at 1.3x Gross MOIC⁽¹⁾ or $171 million. The valuation for Liberty II increased over the period, reflecting production growth, an increase in the Bakken acreage position, and an improvement in the valuation of the company's Powder River Basin acreage.

RCO

As of 30 June 2017, REL, through the Partnership, has invested $87 million of its $125 million commitment to RCO, of which $81 million has been realised to result in $6 million of remaining unrealised invested capital. RCO was formed in January 2015 to take advantage of the dislocation in the leveraged capital markets for energy companies. Since its inception, RCO has made a total of 32 investments, 27 of which have already been fully exited.

As of 30 June 2017, REL's total interest in RCO, through the Partnership, was valued at 1.3x Gross MOIC⁽¹⁾ or $109 million (Realised $81 million, Unrealised $28 million). The valuation decreased slightly over the period, reflecting the mark-to-market value of RCO's remaining underlying securities.

ILX III

As of 30 June 2017, REL, through the Partnership, has invested $94 million of its $200 million commitment to ILX III. ILX III, based in Houston, Texas, is a repeat joint-venture with Ridgewood Energy Corporation. The new entity maintains the same strategy of acquiring non-operated working interests in oil-focussed exploration projects in the shallow Gulf of Mexico. ILX III acquired offshore leases with 15 defined deepwater prospects at inception, but has since opportunistically farmed into two additional prospects and added 12 additional prospects through the 2016 central Gulf of Mexico Lease Sale.

ILX III, in the first half of 2017, drilled three wells, of which two were discoveries. The company has a 73 per cent. success rate on its 11 wells drilled to date and is currently progressing plans to develop its eight discoveries.

As of 30 June 2017, REL's interest in ILX III, through the Partnership, was valued at 1.3x Gross MOIC⁽¹⁾ or $122 million. The valuation multiple remained unchanged over the period.

CNOR

Sierra is an independent Mexican energy company established to pursue select upstream and midstream opportunities in Mexico. Sierra's consortiums have won five offshore blocks to date, which make Sierra the third-largest non-state owned E&P company in Mexico by net acreage, with approximately 560,000 net acres.

Subsequent to the period end, a consortium consisting of Sierra, Talos (a Riverstone portfolio company) and Premier Oil PLC announced a historic oil discovery in the shallow waters of the Gulf of Mexico. The Zama 1 well, located in Mexico's Block 7, confirmed the presence of a light oil resource estimated to be in the range 1.4 billion and 2 billion barrels of oil in place.

As of 30 June 2017, REL's interest in Sierra, through the Partnership, was valued at 1.1x Gross MOIC⁽¹⁾ or $2 million. The valuation remained unchanged over the period.

Realised Investments

Rock Oil

Rock Oil was formed in March 2014 with the strategy of applying Rock Oil's land and technical expertise to the acquisition and development of assets in top-tier North American plays. Since formation, Rock Oil entered into a series of acquisitions to establish a position of approximately 24,783 net acres in the Midland Basin of the Permian, producing approximately 4,900 boepd.

In the third quarter of 2016, Rock Oil agreed to the sale of 100 per cent. of its membership interests to SM Energy Company (NYSE: SM), a U.S. based E&P company. The transaction subsequently closed on 4 October 2016, resulting in gross proceeds to REL of approximately $230 million. This implies a gross multiple of invested capital of 2.0x, a gross IRR of 78 per cent. and a gain of $116 million on the Company's investment, through the Partnership, of $114 million. The MOIC and IRR, net of performance allocation and estimated taxes, are approximately 1.6x and 44 per cent., respectively. The Investment Manager, through RELCP, has subsequently invested the net proceeds of its performance allocation, resulting in the purchase of approximately 590,000 shares in REL.

Approximately $24 million of value is unrealised consisting of escrow payments and mineral acre reserves not included in the sale. As of 30 June 2017, REL's total interest in Rock Oil, through the Partnership, was valued at 2.1x Gross MOIC⁽¹⁾ or $240 million (Realised $216 million, Unrealised $24 million).

CanEra III

During Q1 2017, REL, through the Partnership, terminated its commitment to CanEra III and realised $0.6 million of its $1.4 million investment, or 0.4x Gross MOIC⁽¹⁾.

Origo

In June 2017, REL, through the Partnership, transferred its interest in Origo to Norwegian oil and gas operator DNO ASA for no proceeds.

Going Concern

The Company retained $11.5 million of cash in the IPO and Placing and Open Offer, and received distributions of $5.5 million and $1.1 million from the Partnership in Q1 2016 and Q1 2017, respectively, of which $2.7 million remains at 30 June 2017 (31 December 2016: $3.2 million). This cash balance is sufficient to cover the Company's liabilities as they fall due over the next six months, but the Company will require a $1.0 million distribution in Q1 2018 to cover its forecasted expenses for the initial six months of 2018 of $1.7 million. In accordance with section 4.1(a) of the Partnership Agreement, in the event of the Company requiring additional funds for working capital, it is entitled to receive another distribution from the Partnership.

As at 30 June 2017, the Partnership had $122 million of uninvested funds held as cash and money market fixed deposits (31 December 2016: $268 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 a portfolio company being sold earlier than anticipated or a 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 facts, 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 sub-sectors. Its principal risks are therefore related to market conditions in the energy sector in general, but also the particular circumstances of the businesses in which it is invested through the Partnership. The Investment Manager to 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 2016 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 2017 and no changes are anticipated in the second half of the year.

Subsequent Events

There are no material events after the period end to the date on which these Financial Statements were approved as disclosed in Note 11.

 ⁽¹⁾ Gross MOIC is Gross Multiple of Invested Capital before transaction costs, taxes, 20 per cent. carried interest on gross profit, management fees of 1.5 per cent. of net assets per annum and other expenses. Given these costs and expenses are in aggregate expected to be considerable, Net MOIC will be materially less than the Gross MOIC

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 2017 which comprises the Condensed Statement of Financial Position, the Condensed Statement of Comprehensive Income, the Condensed Statement of Changes in Equity, the Condensed 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 2017 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure Guidance 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 2017

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. The Company's ordinary shares were admitted to the premium segment of the UK Listing Authority's Official List and to trading on the Main Market of the London Stock Exchange as part of its IPO which completed on 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 2016 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 2016.

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 2016.

The Company has not early adopted IFRS 9 and IFRS 15 which are effective from 1 January 2018. The impact of these standards is not expected to be significant as disclosed below:

·      IFRS 9: Financial Instruments - The investment in the Partnership is accounted for at fair value through profit or loss. This treatment, and the related measurement methods, will not change after implementing IFRS 9. Accordingly, the Company does not expect that the implementation of IFRS 9 will have any material impact on its Financial Statements.

·      IFRS 15: Revenue from Contracts with Customers - The Company considers that it does not have any material revenue that falls within the scope of IFRS 15 and hence that the implementation of IFRS 15 will not have a material impact on its Financial Statements.

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 2016.

4.    Taxation

The taxation basis of the Company remains consistent with that disclosed in the Financial Statements for the year ended 31 December 2016.

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.

The Company is exempt from taxation in Guernsey under the provisions of the Income Tax (Exempt Bodies) (Guernsey) Ordinance, 2008 and is charged an annual exemption fee of £1,200.

The Cayman Islands at present impose no taxes on profit, income, capital gains or appreciations in value of the Partnership. There are also currently no taxes imposed in the Cayman Islands by withholding or otherwise on the Company as a limited partner of the Partnership on profit, income, capital gains or appreciations in respect of its partnership interest nor any taxes on the Company as a limited partner of the Partnership in the nature of estate duty, inheritance or capital transfer tax.

Local taxes may apply at the jurisdictional level on profits arising in operating entity investments. Further 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, and Centennial, 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 2017 were $1,665 million (31 December 2016: $1,695 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 2017 and the year ended 31 December 2016. 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 2017 and December 2016.

For the period ended 30 June 2017, 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 2017

Quantitative information about Level 3 fair value measurements as at 31 December 2016

⁽¹⁾  Calculated based on fair values

⁽²⁾ 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

⁽³⁾ Discounted cash flow technique which involves the use of a discount factor of 10 per cent.

The Board reviews and considers the fair value of the Partnership's investments arrived at by the Investment Manager before incorporating such values 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 and such difficulties 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 regular basis.

The Directors have considered whether a discount or premium should be applied to the net asset value of the Partnership. In view of the investment in the Partnership and the nature of the Partnership's assets, no adjustment to the net asset value of the Partnership has been deemed to be necessary.

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.

REL US Centennial Holdings, LLC, a wholly owned subsidiary of the Partnership, has borrowed $100 million under the terms of the Margin Loan Agreement to finance the Company's additional investment in Centennial, through the Partnership. The Margin Loan Agreement is for a term of 18 months and has an annual interest rate cost of 3 month LIBOR plus 3.25 per cent.. A security interest has been granted by REL US Centennial Holdings, LLC over the shares in Centennial, as collateral for any amounts which may become due under the Margin Loan Agreement.

Summary financial information for the Partnership

7.    Contingent liabilities

Contingent liabilities are potential future cash outflows where the likelihood of payment is considered more than remote but is not considered probable or cannot be measured reliably.

Formation and initial expenses

The formation and initial expenses of the Company totalling $22.5 million were paid in full by the Investment Manager. However, if the Investment Management Agreement is terminated by the Company on or before the seventh anniversary of Admission (other than for a material breach by the Investment Manager attributable to its fraud) the Company will be required to reimburse the Investment Manager in respect of the formation and initial expenses of the Company and the costs and the expenses of the Issue to the full extent that such costs and expenses were borne by the Investment Manager. At this time, the Directors consider the likelihood of the Investment Management Agreement being terminated by the Company to be remote.

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 2016: eight).

Directors' fees and expenses for the period ended 30 June 2017 amounted to $444,645, (30 June 2016: $383,791), none of which was outstanding at period end (31 December 2016: $4,137).

Partnership

In accordance with section 4.1(a) of the Partnership Agreement, the Company received distributions from the Partnership of $5.5 million and $1.1 million in Q1 2016 and Q1 2017, respectively, 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 60 in the Financial Statements to 31 December 2016. During the period to 30 June 2017, the Partnership incurred Management Fees of $12,712,420 (30 June 2016: $10,167,646) of which $6,255,015 remained outstanding as at the period/year end (31 December 2016: $6,369,594). 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 2017, the General Partner was entitled to receive incremental Performance Allocation of $2,364,973 (30 June 2016: $10,227,726) of which $134,529,381 (31 December 2016: $132,164,408) remained outstanding as at the period/year end. 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.  (Loss) Earnings per Share and Net Asset Value per Share

(Loss) Earnings per Share

The (Loss) 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 2017 (30 June 2016: none).

Net Asset Value per Share

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

There are no material events after the period end to the date on which these Financial Statements were approved.
