CHAIRMAN’S STATEMENT FOR THE SIX MONTHS ENDED 30 JUNE 2020

MARKET OVERVIEWThe past six months have proved extremely challenging for markets, with all-time highs in global equities in February 2020 followed by the outbreak of the COVID-19 pandemic. The pandemic prompted countries to adopt varying degrees of social distancing, self-quarantine and lockdown measures which severely curtailed economic activity in most economies and resulted in an unprecedented near-term contraction. Market jitters were compounded by plunging oil prices, following heightened political tensions between the major oil producing nations.

Policy response, with significant fiscal and monetary stimulus, cushioned the devastating impact of the virus shock and helped turn markets around in late March. Oil prices also partially recovered and most mined commodity prices have remained resilient. The rebound in global equity markets has been sharp and they have continued to recover on the back of improving economic data and as economies gradually begin to emerge from lockdown. However, high market volatility is expected to continue until the full implications of COVID-19 become clearer.

PERFORMANCEOver the six months ended 30 June 2020, the Company’s net asset value (NAV) returned +3.4% and the share price +3.7%. The Company’s reference index, the MSCI ACWI Metals & Mining 30% Buffer 10/40 Index (MSCI ACWI) returned -0.7% (all percentages calculated in sterling terms with dividends reinvested). As discussed in my annual statement to shareholders, the Board concluded that the MSCI ACWI is a better reference tool to measure the Company’s performance over time and was therefore introduced from the start of the new financial year.

As mentioned in the Investment Manager’s Report, the Company’s strong relative result compared with most other sectors has been as a result of its exposure to highly cash generative companies such as iron ore producers, as well as to gold miners which have continued to sell production at gradually rising prices.

Since the period end and up to the close of business on 17 August 2020, the Company’s NAV has increased by 10.3% compared to a rise of 10.2% (on a net return basis) in the reference index (with income reinvested).

REVENUE RETURN AND DIVIDENDSThe Company’s net revenue earnings for the six months to 30 June 2020 amounted to 8.82p per share (six months to 30 June 2019: 11.43p per share) a decrease of 22.8%. Only four special dividends totalling £330,000 were received in the period under review, whilst six special dividends totalling £10.2 million were received during the corresponding six-month period in 2019. All special dividends have been taken to revenue, with the exception of one special dividend amounting to £34,000 which was taken to capital (2019: one special dividend of £5.2 million taken to capital).

Despite many sectors struggling to pay dividends during the COVID-19 crisis, there are others that are proving to be more resilient. Some of the mining companies in the Company’s portfolio are well-positioned on the dividend front, given their balance sheet strength and free cash flow generation.

The first quarterly dividend of 4.00p per share was paid on 26 June 2020 and, today, the Board has announced a second quarterly dividend of 4.00p per share which will be paid on 25 September 2020 to shareholders on the register on 28 August 2020, the ex-dividend date being 27 August 2020.

DISCOUNTThe discount of the Company’s share price to the underlying NAV per share finished the period under review at 12.2% on a cum income basis, having stood at 11.6% at the beginning of the period. At the close of business on 17 August 2020, the Company’s shares were trading at a discount of 11.9% on a cum income basis.

During January and February, the Company bought back 1,179,707 shares into treasury at a total cost of £4,400,000. As the COVID-19 pandemic took hold and market conditions deteriorated during March, the Company’s share price fell sharply and the discount briefly widened to 22.5% before rapidly narrowing again. The Board recognises the importance to investors that the market price of the Company’s shares should not trade at a significant discount to the underlying NAV, and share buybacks will be undertaken in normal market conditions when, in the view of the Board, it is in the best interests of shareholders to do so.

GEARINGThe Company operates a flexible gearing policy which depends on prevailing market conditions. It is not intended that gearing will exceed 25% of the net assets of the Company and its subsidiary. Gearing as at 30 June 2020 was 9.8% and maximum gearing during the period was 15.6%.

FRANKED INVESTMENT INCOME GROUP LITIGATION ORDER V HMRCAs reported in the Company’s 2018 Annual Report, we were pleased to receive a positive outcome on a tax ruling relating to overseas dividends with the UK Supreme Court handing down its judgement in the Prudential Case on 25 July 2018. In August 2020, HM Revenue & Customs (HMRC) accepted that the Company was entitled to claim double tax relief in relation to underlying tax suffered on dividends received from non-UK companies in a number of past accounting periods.

While the amount of repayment has not been formally agreed with HMRC and, as such, a degree of uncertainty still remains, the Board has been advised that the receipt of a repayment in respect of these amounts had become sufficiently probable to merit recognition in the Company’s NAV. As a result, it was announced today that an asset of £2,560,568 had been reflected in the NAV in respect of these claims. As the original tax expense fell within the revenue column of the consolidated income statement, the benefit of this recovery has been credited to the revenue column of the consolidated income statement. It will result in an increase of 1.47 pence per share to the Company’s revenue earnings per share for the year ending 31 December 2020. More information is given in note 17.

OUTLOOKAt the beginning of the year a continuation of modest economic growth was the base case expectation but now we are contemplating a deep economic downturn of unknown duration. We anticipate continued volatility for the mining sector and broader equity market. Economies are slowly restarting, but the pace of activity depends on how successful countries are in suppressing the virus as they reopen.

Mining companies should be well-placed to withstand the economic weakness relative to other sectors given their balance sheet strength. Strong capital discipline should also help miners weather the volatility, as well as the sector being a key beneficiary of increased infrastructure spending and a recovery in demand. Whilst huge uncertainties remain over the short-term outlook, the quality bias in the portfolio, with a focus on companies with stronger balance sheets and lower costs, should hold the Company in good stead.

DAVID CHEYNEChairman19 August 2020

INVESTMENT MANAGER’S REPORT

The first half of 2020, whilst being extremely volatile, ended far better than expected given the massive economic tremors caused by the outbreak of the COVID-19 virus. The prior years of capital discipline and shrewd management decisions meant mining companies were in a strong position to navigate through this period far better than in prior recessions. The reference index, the MSCI ACWI Metals & Mining 30% Buffer 10/40 Index net total return in sterling, was down by 0.7% during the period, versus the FTSE All Share (with dividends reinvested) in sterling which was down by 17.4%.

The impact of the virus on the global economy has been enormous. The way in which it rapidly moved around the world likened it to a rolling blackout of economic activity. Businesses and general industry were rapidly shut down, people were moved into lockdown and financial markets responded with huge downward moves. The uncertainty generated by this, combined with the still fresh memories of the 2008 global financial crisis, triggered a rush for cash which meant waves of selling by investors. Fortunately, central banks were quick to act, and they put in place unprecedented measures designed to protect the financial plumbing of world markets. This stabilised indices and allowed the least impacted sectors to recover swiftly in terms of valuations.

Over the period the net asset value (NAV) of the Company was up by 3.4% with dividends reinvested. Given the huge falls in other sectors, this is a strong relative result especially when compared to previous crises where the mining sector has more often than not been one of the worst places to be invested. In addition, compared to the relative return of world markets, the Company also benefited from its exposure to highly cash generative companies, such as iron ore producers, as well as to gold miners who continue to sell production at gradually rising prices.

HARD WORK PAYS OFFFor the last few years we have written about the lengths mining company management teams and Boards have gone to rebuild trust between the companies and their owners, the shareholders. New frameworks were put into place to reduce the chance of poor capital allocation decisions and entrench the businesses into a culture of shareholder driven returns. The consequence of this was a much more robust business model, where companies have underspent compared to the previous period of extravagance and a more prudent level of balance sheet gearing. During the last few years, this generated large amounts of free cash flow which was returned to shareholders. This left the sector in the unusual position of being much better prepared for a crisis, which was fortunate given the recent events in the first half of the year.

BALANCE SHEET STRENGTHOn top of robust finances, the sector has broadly managed the operational side very well. There has been limited interruption to business in key regions such as the Pilbara in Australia, but the same cannot be said for other areas such as the Andean copper belt in Peru and Chile. These two areas have seen significant falls in copper production during the last few months as operations ceased to help manage the virus outbreak. Other notable areas impacted by the lockdowns were platinum supply from South Africa and physical gold supply from refineries. In summary, the main impact has been to reduce production of raw materials at a time of demand weakness, which has reduced the build-up of inventories normally associated with an economic slowdown. The absence of a typical overhang has allowed prices to recover sharply from the initial economic shock and bodes well for future returns should the virus now be contained.

The US-China trade war has overshadowed the sector since mid-2018. Following months of prolonged negotiations, the long-awaited phase one deal was signed in January this year with China pledging to buy US$200 billion of US goods. Initially, despite scepticism over targets being met, this provided some relief to the sector. However, it was quickly forgotten, with governments’ focus turning to managing the COVID-19 pandemic. In recent months US-China relations have continued to worsen with the US President blaming the Chinese government for failing to contain the COVID-19 outbreak, putting further progress on trade negotiations at risk. At first pass this would appear negative for industrial demand. However, the impact of deglobalisation and a greater desire for onshoring has the potential to be inflationary and actually positive for commodity demand. While we continue to see trade tensions as a risk factor for the sector, we anticipate the impact to be more muted in the medium term.

ESG AND THE SOCIAL LICENSE TO OPERATEEnvironmental, Social and Governance (ESG) is of critical importance to the mining sector and the Portfolio Managers spend a considerable amount of time understanding the ESG risks and opportunities facing companies and industries in the portfolio. As an extractive industry, the mining sector naturally faces a number of ESG challenges given its dependence on water, carbon emissions and geographical location of assets. However, we feel the sector underemphasises the many positive ESG benefits it provides to society through the provision of critical infrastructure, taxes and employment to local communities, providing materials essential to human progress, enabling the carbon transition through the production of sustainable metals and the continuing improvements to health & safety standards across the industry.

Rio Tinto, Norilsk Nickel and Vale have been the key ESG focus areas during the first half of the year. Following the events at Juukan Gorge in late May, Rio Tinto has launched a board-led review of its heritage management processes and will examine the company’s relationship and communications with the Puutu Kunti Kurrama and Pinikura people (PKKP). The review will be made public and is due to be released in October 2020, involving consultation with the indigenous leaders, traditional owners, subject matter experts and Rio Tinto employees. We look forward to receipt of the report.

Norilsk Nickel has been under significant scrutiny following an oil spill in May which saw circa 21,000 tonnes of diesel spill into the Artic region with the Russian President declaring a state of emergency in the region. Norilsk Nickel has been ordered to pay US$2.1 billion in fines and damages, with Norilsk Nickel disputing the methodology used to calculate the damage caused by the oil spill.

Vale has been under ESG scrutiny following the tailings dam incidents at Samarco in 2015 and the Brumadinho collapse in 2019. Both events saw tragic loss of life and resulted in a heavy focus on tailings dam management across the sector. Vale is committed to restoring Brumadinho and rebuilding its pact with society. The company has US$4 billion in provisions related to Brumadinho and will also invest US$1.8 billion in dry stacking to reduce the reliance on tailings dams. Vale has implemented a number of changes to its tailings dam management process following an independent review to ensure it is aligned with the highest level of international practices.

DIVERGENCEDuring the first half of 2020 the spread of returns within the commodity complex has been as wide as we have ever seen. Iron ore prices remained rock solid throughout the period, as ongoing supply issues in Brazil kept markets tight despite the COVID-19 led recession. Gold prices have been stellar due to the move to near zero interest rates across the world and the weak US dollar. Finally, the price of palladium moved to unprecedented levels on the back of supply concerns and improved loadings in heavy duty vehicles. These rises are in stark contrast to the large falls in base metals prices during the period. Miners of zinc, tin, aluminium, copper and lead saw double digit percentage falls in average prices year-on-year leaving some metal prices below marginal costs of supply, for example aluminium where capacity is being closed by key supply producers such as Rio Tinto. Coal miners also suffered as prices fell deep into the cost curve on the back of ongoing cuts to demand, as the world transitions more rapidly towards a lower carbon economy.

On the back of the wide range of moves in metal prices, the spread of returns in the equities has been equally wide. Amongst the industrial commodities, key holdings such as Rio Tinto, BHP and Anglo American have materially outperformed others with greater exposure to base metals such as Glencore. In addition, non-copper producers have fared far worse than key holdings in Freeport-McMoRan Copper & Gold, Lundin Mining and Antofagasta. Finally, the gold equities outperformed almost all other holdings as margins and cash flow meaningfully expanded as the gold price rose and by the end of the period our position in gold companies had risen to 35.2% of the portfolio (31 December 2019: 23.2%).

In addition to commodity prices, geographic location has been a significant driver of returns as governments imposed different restrictions on mining operations in response to COVID-19. For example, in Australia, iron producers have been able to operate at close to full capacity throughout the period, versus producers in Peru, South Africa, Mexico and Canada that were forced to reduce people at site and mining rates in response to the virus. We have also seen a large divergence in demand by geography, the most notable in steel, where Chinese steel demand has recovered strongly underpinning demand for iron ore, whilst European steel demand has waned putting pressure on coking coal prices which were down by 43% during the first half of the year.

Amidst the commodity price volatility in the first half of the year, margins have generally held up better across the sector given the absence of cost inflation. The sharp move down in oil prices and commodity currencies such as the Brazilian real and South African rand, has helped to buffer the downward move in prices year to date. Anglo American and Vale have enjoyed a strong tailwind from foreign exchange rates this year and we expect this to become apparent in the second half as operating volumes improve for both companies.

SELECTED COMMODITY PRICE CHANGES DURING FIRST HALF OF 2020

DIVIDEND LED ROTATION?In recent reports we have emphasised and applauded the improved capital discipline across the sector, which today sees the sector with one of the strongest balance sheets globally, enabling the companies to offer an attractive dividend yield to investors. Since 2018 we have seen a step up in returns via dividends and last year we saw record dividends paid by BHP and Rio Tinto due to a combination of high iron ore prices and asset sales.

Given the dividend challenges faced by companies globally and especially in the UK, versus the market’s ongoing desire for yield, we believe there is potential for investors who are desperately searching for income to increasingly look towards this sector for income. Should this come to pass it might trigger a rotation of capital from other sectors back into the mining shares and in turn compress the dividend yield premium that the mining sector trades on.

As we look towards the second half of the year, we remain broadly optimistic on the outlook for dividends particularly for the iron ore exposed diversified miners given the strength in prices year to date. The absolute level of dividends will be ultimately dictated by the underlying commodity prices. However, given balance sheet strength, the limited calls on growth capital and companies’ strong commitment to adhere to their capital allocation strategies, we continue to believe the mining sector can deliver a healthy level of income for shareholders. To date, we have seen limited dividend cuts across the sector, with Glencore (not in the portfolio) cutting its dividend, Antofagasta reducing its announced dividend and Freeport-McMoRan Copper & Gold cutting its quarterly dividend in March, as the copper price bottomed. Conversely, we have seen strong dividend increases from a number of gold companies with Newmont Corporation raising its quarterly dividend by 79% and other smaller players doubling dividend payments. Today, the gold companies trade on modest dividend yields in absolute terms; however, given the increase in free cash flow generation this year, we look forward to higher distributions coming through and with fixed income returns setting a low bar maybe even a premium yield is reached.

GROWTH AND RESOURCE REPLENISHMENTVolume growth across the sector has been limited in recent years. However, we continue to selectively look for and invest in quality growth companies. The majority of the Company’s growth focused investments are copper and gold producers given the need for additional supply to be added to these markets longer term. Key growth investments in the portfolio include Ero Copper, Ivanhoe Mines, Anglo American, Nickel Mines, Northern Star Resources and Teranga Gold.

Ero Copper, a Brazilian based copper producer, has been a standout investment for the Company, up almost 400% since its Initial Public Offering (IPO) in 2017. While the shares have traded down in the first half of 2020, Ero Copper continues to have exploration success, most recently drilling its highest grade-meter intercept at the Pilar mine in the company’s new ‘Superpod’ discovery – the Pilar Deepening Extension zone. Ero Copper continues to pursue its significant exploration programme, focused on existing assets and regional exploration, which has the potential to both increase production and extend mine life.

Another successful growth investment for the Company has been Nickel Mines, an Australian listed, Indonesian based nickel producer. In less than two years since its IPO, Nickel Mines has become a globally significant nickel producer with attributable nickel production of 35ktpa. During the first half of the year, the company exercised its right to increase its interest in two Rotary Kiln Electric Furnace (RKEF) projects to 80% raising A$231 million via a fully underwritten entitlement offer. This transformative transaction consolidates Nickel Mines’ position as a Tier 1 global nickel producer.

Among the Company’s larger holdings, Anglo American is actively pursuing growth targeting to increase copper production to circa 1Mt via the development of Quellaveco in Peru and is also studying an expansion of the Collahuasi Copper mine in Chile. In addition to copper, Anglo American has near-term growth in iron ore and metallurgical coal and in the first half of the year acquired the Woodsmith project via the acquisition of Sirius Minerals. Woodsmith is a longer-dated growth option for Anglo American which believes this has the potential to be a Tier 1 asset for the company with US$1.1 billion already invested in the project and all key permits in place.

In addition to volume growth, companies that have successfully invested in exploration through the cycle and have sufficient asset quality to replenish reserves and resources, we believe will be strong outperformers in this next phase of the cycle. This is particularly prevalent amongst the gold companies given their shorter mine lives and greater need for reinvestment. There has been a resurgence in junior and mid-cap gold companies this year with a number of deals announced during the first half of 2020. In the Company, we have been able to take advantage of this via our holding in Teranga Gold which acquired the Massawa project from Barrick Gold, as well as Northern Star Resources which raised equity at the end of 2019 to acquire 50% of KCGM (the Superpit) from Newmont Mining. Northern Star Resources along with its joint venture partner at the asset, Saracen, will look to update the market on the longer-term potential of the asset in September, which has the potential to be a cornerstone asset for the company.

SUSTAINABLE METALSThe shift towards electric vehicles (EVs) is one of the strongest trends we foresee. We expect a more than 10-fold increase in the size of the market by 2030, which creates growth opportunities for those companies supplying the materials that enable that transition.

Transportation has been impacted by the COVID-19 pandemic given the significant restrictions imposed on the movement of individuals over recent months. The sale of new vehicles has been significantly affected, with passenger car sales falling 80% year-on-year at the trough in both China and Europe. Encouragingly, sales in China have rebounded sharply and there is evidence in China that the virus is encouraging people to favour car ownership in order to avoid the use of public transport.

Looking ahead, it is actually possible that the outlook for the theme has been strengthened by recent events. More importantly, we are seeing government stimulus focused on restarting economies post lockdown, target sustainable themes, with EVs an important pillar of that, which has the potential to further accelerate the transport revolution. In Europe, for instance, the market share of EVs has increased every month so far this year and overall, the year to date share of EVs is around 7%, which is more than double what it was in 2019.

In China, the government has extended its subsidies for EVs by two years. In Europe, France has increased its EV subsidies by over 15%. Germany has gone even further, announcing a doubling of its EV subsidy and a temporary reduction in VAT, and has mandated that refuelling stations install EV charging points. The decision by the German government to only introduce automotive support measures for EVs is an incredibly powerful message about the industry’s future direction.

The main raw materials that go into EV batteries are cobalt, nickel and lithium. For cobalt we saw a price recovery, post a weak second half in 2019, with London Metal Exchange prices up by 12.9% in the first half of 2020. Last year Glencore acted to balance the cobalt market with a decision to suspend the Mutanda project in the Democratic Republic of Congo for two years, impacting 20% of global supply. In April, Glencore announced the acquisition of Katanga Mining from the minority equity holders, including the Company. This transaction was completed in June 2020.

Prices for lithium moved lower throughout the year, down 27% in the first half of 2020. As well as the tempered growth outlook, prices have been hit by increased supply of Australian lithium concentrate. Prices continue to be low enough for supply to be exiting the market and projects to be halted. In March 2020, we saw China’s Tianqi Lithium postpone commissioning of their Australian lithium conversion project in Kwinana and we have also seen Albemarle cut capital expenditure and delay projects whilst preserving optionality. The Company exited Albemarle during the first half of the year, redeploying this capital into other opportunities. The Company continues to be exposed to lithium through its holdings in the Pilgangoora Bond and Neo Lithium. Another major battery metal is nickel where demand is likely to benefit from the increased penetration of EVs and thus demand for lithium batteries which contain nickel in the cathode of the battery.

2020 has seen growing excitement about the potential for hydrogen to disrupt the commercial vehicle market. Compared to batteries, hydrogen and fuel cells offer better energy density, improved range and faster refuelling, giving them an inherent advantage in efforts to decarbonise the heavy truck market. That said, there are substantial hurdles to overcome, with costs needing to fall dramatically for the switch to be economic. We see the technology’s long-term potential but believe that we are still in the early stages of its development. Technologies involving platinum are crucial to the adoption of hydrogen fuel cell and electrolyser technologies. The Company’s positions in Impala Platinum, Northam Platinum, Anglo American and Norilsk Nickel provide exposure here.

ROYALTIES AND UNQUOTED INVESTMENTSThe Company currently has one unquoted investment, the OZ Minerals Brazil Royalty representing 2.1% of the portfolio as at the end of June. The Company has an additional quoted royalty investment, the Vale Debentures, representing 3.3% of the portfolio, with total royalty investments equal to 5.4% of the portfolio. These, and any future investments, will be managed in line with the guidelines set by the Board, as outlined to shareholders in the Strategic Report in the Annual Report.

OZ MINERALS BRAZIL ROYALTY CONTRACT (2.1%)In July 2014 the Company signed a binding royalty agreement with Avanco Minerals. The Company provided US$12 million in return for Net Smelter Return (net revenue after deductions for freight, smelter and refining charges) royalty payments comprising 2% on copper, 25% on gold and 2% on all other metals produced from mines built on Avanco’s Antas North and Pedra Branca licenses. In addition, there is a flat 2% royalty over all metals produced from any other discoveries within Avanco’s license area as at the time of the agreement.

In 2018 we were delighted to report that Avanco was successfully acquired by OZ Minerals, an Australian based copper and gold producer for A$418 million, with the royalty now assumed by OZ Minerals. Since our initial US$12 million investment was made, we have received US$13.4 million in royalty payments, with the royalty achieving full payback on the initial investment. As at the end of June 2020, the royalty was valued at £16.8 million (2.1% of the portfolio) which equates to a 185.0% total return since our investment.

In November 2019, OZ Minerals approved the development of the Pedra Branca underground mine and released a feasibility study and mine plan detailing an eight year life of the mine. This mine will provide ore to the existing processing facilities at Antas from mid-2021. OZ Minerals has guided for the Antas North mine to be closed in 2021. The Pedra Branca mine is the first spoke in the Carajas Antas Hub strategy which OZ Minerals outlined in July 2019, a low risk, modest capital, hub strategy with processing infrastructure serving multiple small to mid-scale mines. Exploration activities continue in the Carajas region with OZ Minerals detailing an Exploration Target of 2.0-4.0 million tonnes at a grade of 3.1-5.0% copper at their Clovis Prospect, which is around 2km from Antas.

From a valuation perspective, last year’s positive decision to mine on Pedra Branca resulted in a lower discount rate applied on the cash flow from this mine in the valuation, which offset the more conservative assumptions on the Pedra Branca mine. Since then the Antas mine operation, Pedra Branca development and royalty payments have continued to plan, with no material impact from the COVID-19 pandemic on production or costs. As such, the Directors have chosen to keep the value unchanged, save for the impact of royalty payments paid. An independent valuation of the royalty was also completed at the end of 2019.

VALE DEBENTURES (3.3%)At the beginning of 2019, the Company completed a significant transaction to increase its holding in Vale Debentures. The debentures consist of a 1.8% net revenue royalty over Vale’s Northern System and Southeastern System iron ore assets in Brazil, as well as a 1.25% royalty over the Sossego copper mine. The iron ore assets are world class given their grade, cost position, infrastructure and resource life which is well in excess of 50 years. As at the end of June 2020, the portfolio’s exposure to the Vale Debentures was 3.3%.

The iron ore market has been significantly altered following Vale’s tragic tailings dam incident at the beginning of 2019. In 2019, Vale’s production was circa 80Mt lower than initially forecast following the tailings dam failure and the requirement to suspend all upstream tailings dams. This saw the iron ore price increase by 28.1% in 2019, significantly above the market’s expectation of prices. This year, the iron ore market has continued to remain tight with disappointing production volumes from Vale due to the heavy wet season in Brazil and rising COVID-19 risk in the country. This has seen the iron ore price average at US$92/t during the first half of 2020, well above estimates used when the deal was concluded to increase the holding two years ago.

Vale has provisioned US$4 billion (as at March 2020) for Brumadinho to restore the environment and communities impacted by the incident. However, it is important to note that this cost is not borne by the debentures as it is a revenue royalty with payments directly linked to the iron ore price. At present, the Vale Debentures are only making royalty payments from the Northern System, with a total dividend payment of R$2.32/debenture in 2019 (equivalent to US$172.8 million), of which R$1.30/debenture was received in the first half of 2020. Vale currently anticipates that royalty payments from the Southeastern System will commence in June 2024 versus previous guidance of 2023, due to the impact of Brumadinho.

Vale’s Northern System is currently producing at 200Mt and forecast to grow to 230Mt once S11D ramps up, while the Southeastern System is currently operating at circa 70Mt and is expected to remain around this level. Vale has indicated that it is studying increasing production at the Northern System to further increase dry-processing operations and reduce its usage of tailings dams, which provides additional upside to our original expectations.

Whilst the Vale Debentures are a royalty, they are also a listed security on the Brazilian National Debentures System. However, shareholders should be aware that historically there has been a low level of liquidity in the debentures and price volatility is to be expected.

We continue to actively look for opportunities to grow royalty exposure, given it is a key differentiator of the Company and an effective mechanism to lock-in long-term income which further diversifies the Company’s revenues.

DERIVATIVES ACTIVITYThe Company from time to time enters into derivatives contracts, mostly involving the sale of ‘put’ and ‘call’ options. These are taken to revenue and are subject to strict Board guidelines which limit their magnitude to an aggregate 10% of the portfolio. In the first half of 2020 income generated from options was £4.4 million. During the period, the increase in market volatility presented a range of opportunities to monetise value for the Company and this resulted in a 40.4% increase in option income versus the first half of 2019. At the end of the period, the Company had 2.5% of net assets exposed to derivatives and the average exposure to derivatives during the period was once again less than 5%.

GEARINGAt 30 June 2020, the Company had £97.1 million of net debt, with a gearing level of 9.8%. The debt is held principally in US dollar rolling short-term loans and managed against the value of the debt securities and the high yielding royalty positions in the Company. During the period, the underlying investments in fixed income securities evolved as some were reduced and one new position was added. Outside of this, total indebtedness has been reduced over the period due to the uncertainty in markets and the better returns available outside of the fixed income sector.

OUTLOOKGiven the rapid response from central banks and governments, financial markets have reacted well to the support mechanisms put in place. The next phase is a balancing act between restarting the economy, whilst trying to minimise a sizable second wave virus outbreak. At the time of writing, the fiscal measures that have been announced are extremely supportive for growth and should the dollars be deployed in a reasonable time then industrial commodities are likely to benefit from this.

Unlike in previous periods of economic disruption, the mining sector has fared much better largely due to the time spent rebuilding the businesses post the 2015 low. With first half results highlighting the strong cash flows and decent yields, there is the prospect that those investors looking for quality equity income investments rotate into the resources sector allowing the consensus underweight positions to reduce. If this happens, the shares are likely to rerate towards historic multiples delivering material upside from current levels.

Historic data shows that the largest and most consistent contributor to total shareholder returns in the mining sector comes from dividends. With this in mind, it is the aim of the Company to maximise the opportunities to enhance the yield of the portfolio to allow the Company to deliver a superior total return for its shareholders through the cycle.

GOVERNANCE

INTERIM MANAGEMENT REPORT AND RESPONSIBILITY STATEMENT

The Chairman’s Statement and the Investment Manager’s Report give details of the important events which have occurred during the period and their impact on the financial statements.

PRINCIPAL RISKS AND UNCERTAINTIESThe principal risks faced by the Company can be divided into various areas as follows:

• Counterparty;

• Investment performance;

• Legal & Compliance;

• Market;

• Operational;

• Financial;

• Marketing; and

• Securities lending.

The Board reported on the principal risks and uncertainties faced by the Company in the Annual Report and Financial Statements for the year ended 31 December 2019. A detailed explanation can be found in the Strategic Report on pages 44 to 46 and note 18 on pages 99 to 115 of the Annual Report and Financial Statements which is available on the website maintained by BlackRock at www.blackrock.com/uk/brwm.

In the view of the Board, the outbreak of an infectious respiratory illness caused by a novel coronavirus known as COVID-19, that was first detected in China in December 2019 and has developed into a global pandemic, has fundamentally altered the nature of the risks reported in the Annual Report and Financial Statements. The coronavirus has resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19 has adversely affected the economies of many nations across the entire global economy, individual issuers and capital markets, and could continue to an extent that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty.

In the view of the Board, with the exception of COVID-19, there have not been any changes to the fundamental nature of the risks set out in the Annual Report and these principal risks and uncertainties are equally applicable to the remaining six months of the financial year as they were to the six months under review. The Board recognises the benefits of a closed-end structure in extremely volatile markets such as those experienced during the COVID-19 pandemic. Unlike open ended counterparts, closed-end funds are not obliged to sell down portfolio holdings at low valuations to meet liquidity requirements for redemptions. During times of elevated volatility and market stress, the ability of the closed-end structure to remain invested for the long term enables the Portfolio Managers to adhere to disciplined fundamental analysis from a bottom-up perspective and be ready to respond to dislocations in the market as opportunities present themselves.

Going concernThe Board is mindful of the uncertainty surrounding the potential duration of the COVID-19 pandemic and its impact on the global economy, the Company’s assets and the potential for the level of revenue derived from the portfolio to reduce versus the prior year. The Portfolio Managers will continue to review the composition of the Company’s portfolio and to be pro-active in taking investment decisions as necessary.

The Directors, having considered the nature and liquidity of the portfolio, the Company’s investment objective and the Company’s projected income and expenditure, are satisfied that the Company has adequate resources to continue in operational existence for the foreseeable future and is financially sound. The Board believes that the Company and its key third party service providers have in place appropriate business continuity plans and these services have continued to be supplied without interruption throughout the COVID-19 pandemic.

The Company has a portfolio of investments which are predominantly readily realisable and is able to meet all of its liabilities from its assets and income generated from these assets. Accounting revenue and expense forecasts are maintained and reported to the Board regularly and it is expected that the Company will be able to meet all its obligations. Borrowings under the overdraft and revolving credit facilities shall at no time exceed £180 million or 25% of the Group’s net asset value (whichever is the lower) and this covenant was complied with during the period. Based on the above, the Board is satisfied that it is appropriate to continue to adopt the going concern basis in preparing the financial statements. Ongoing charges (excluding finance costs, direct transaction costs, custody transaction charges, non-recurring charges and taxation) for the year ended 31 December 2019 were approximately 1.02% of net assets.

Related party disclosure and transactions with the AIFM and Investment ManagerBlackRock Fund Managers Limited (BFM) was appointed as the Company’s Alternative Investment Fund Manager (AIFM) with effect from 2 July 2014. BFM has (with the Company’s consent) delegated certain portfolio and risk management services, and other ancillary services, to BlackRock Investment Management (UK) Limited (BIM (UK)). Both BFM and BIM (UK) are regarded as related parties under the Listing Rules. Details of the management and marketing fees payable are set out in notes 4 and 5 respectively and note 12.

The related party transactions with the Directors are set out in note 13.

Directors’ responsibility statementThe Disclosure Guidance and Transparency Rules (DTR) of the UK Listing Authority require the Directors to confirm their responsibilities in relation to the preparation and publication of the Interim Management Report and Financial Statements.

The Directors confirm to the best of their knowledge that:

• the condensed set of financial statements contained within the half yearly financial report has been prepared in accordance with International Accounting Standard 34 ‘Interim Financial Reporting’; and

• the Interim Management Report, together with the Chairman’s Statement and Investment Manager’s Report, include a fair review of the information required by 4.2.7R and 4.2.8R of the FCA’s Disclosure Guidance and Transparency Rules.

This half yearly financial report has been reviewed by the Company’s auditors and their report is set out below.

The half yearly financial report was approved by the Board on 19 August 2020 and the above responsibility statement was signed on its behalf by the Chairman.

CONSOLIDATED STATEMENT OF FINANCIAL POSITION AS AT 30 JUNE 2020

CONSOLIDATED CASH FLOW STATEMENT FOR THE SIX MONTHS ENDED 30 JUNE 2020

* Includes payment of £0.88m made on settlement of share buybacks on 30 December 2019 and 31 December 2019.

NOTES TO THE FINANCIAL STATEMENTS FOR THE SIX MONTHS ENDED 30 JUNE 2020

1. PRINCIPAL ACTIVITYThe principal activity of the Company is that of an investment trust company within the meaning of Section 1158 of the Corporation Tax Act 2010.

The principal activity of the subsidiary, BlackRock World Mining Investment Company Limited, is investment dealing.

2. BASIS OF PREPARATIONThe half yearly financial statements for the period ended 30 June 2020 have been prepared in accordance with the Disclosure Guidance and Transparency Rules sourcebook of the Financial Conduct Authority and with International Accounting Standard 34 (IAS 34), ‘Interim Financial Reporting’, as adopted by the European Union (EU). The half yearly financial statements should be read in conjunction with the Company’s Annual Report and Financial Statements for the year ended 31 December 2019, which have been prepared in accordance with International Financial Reporting Standards (IFRS) as adopted by the EU and as applied in accordance with the provisions of the Companies Act 2006 and in accordance with IAS 34 Interim Financial Reporting.

Insofar as the Statement of Recommended Practice (SORP) for investment trust companies and venture capital trusts, issued by the Association of Investment Companies (AIC) in October 2019, is compatible with IFRS, the financial statements have been prepared in accordance with guidance set out in the SORP.

Adoption of new and amended standards and interpretationsAmendments to IFRS 3 – Definition of a business (effective 1 January 2020). This amendment revised the definition of a business.

This standard did not have any impact on the Group.

Amendments to IAS 1 and IAS 8 – Definition of material (effective 1 January 2020). The amendments to IAS 1, ‘Presentation of Financial Statements’, and IAS 8, ‘Accounting Policies, Changes in Accounting Estimates and Errors’, and consequential amendments to other IFRSs required companies to:

(i) use a consistent definition of materiality throughout IFRSs and the Conceptual Framework for Financial Reporting;

(ii) clarify the explanation of the definition of material; and

(iii) incorporate some of the guidance of IAS 1 about immaterial information.

This standard did not have any impact on the Group.

Amendments to IFRS 9, IAS 39 and IFRS 7 – Interest rate benchmark reform (effective 1 January 2020). These amendments provided certain reliefs in connection with the interest rate benchmark reform. These reliefs relate to hedge accounting and have the effect that the Inter Bank Offer Rate (IBOR) reform should not cause hedge accounting to terminate.

This standard did not have any impact on the Group.

IFRS standards that have yet to be adoptedIFRS 17 – Insurance contracts (effective 1 January 2021). This standard replaces IFRS 4, which currently permits a wide range of accounting practices in accounting for insurance contracts. IFRS 17 will fundamentally change the accounting by all entities that issue insurance contracts and investment contracts with discretionary participation features. The standard has not been endorsed by the EU.

This standard is unlikely to have any impact on the Group as it has no insurance contracts.

3. INCOME

During the period, the Group received option premium income in cash totalling £4,611,000 (six months ended 30 June 2019: £3,002,000; year ended 31 December 2019: £5,986,000) for writing put and covered call options for the purposes of revenue generation.

Option premium income is amortised evenly over the life of the option contract and accordingly, during the period, option premiums of £4,446,000 (six months ended 30 June 2019: £3,166,000; year ended 31 December 2019: £6,008,000) were amortised to revenue.

At 30 June 2020 there were two open positions (30 June 2019: one; 31 December 2019: five) with an associated liability of £425,000 (30 June 2019: £337,000; 31 December 2019: £314,000).

Dividends and interest received in cash in the six months ended 30 June 2020 amounted to £12,758,000 and £1,516,000 (six months ended 30 June 2019: £14,366,000 and £4,312,000; year ended 31 December 2019: £27,581,000 and £8,252,000) respectively.

Special dividends of £34,000 have been recognised in capital for the six months ended 30 June 2020 (six months ended 30 June 2019: £5,229,000; year ended 31 December 2019: £5,229,000).

4. INVESTMENT MANAGEMENT FEE

The investment management fee (which includes all services provided by BlackRock) is 0.8% of the Company’s net assets. However, in the event that the NAV per share increases on a quarter-on-quarter basis, the fee will then be paid on gross assets for the quarter. During the period £2,490,000 (30 June 2019: £2,948,000; 31 December 2019: £5,888,000) of the investment management fee was generated from net assets and £113,000 (30 June 2019: £336,000; 31 December 2019: £592,000) from the gearing effect on gross assets due to the quarter-on-quarter increase in the NAV per share for the period as set out below:

The daily average of the net assets under management during the period ended 30 June 2020 was £672,597,000 (30 June 2019: £727,181,000; 31 December 2019: £733,356,000).

The fee is allocated 25% to the revenue column and 75% to the capital column of the Consolidated Statement of Comprehensive Income.

5. OTHER OPERATING EXPENSES

6. FINANCE COSTS

Finance costs are charged 25% to the revenue column and 75% to the capital column of the Consolidated Statement of Comprehensive Income.

7. DIVIDENDSThe final dividend of 10.00p per share for the year ended 31 December 2019 was paid on 7 May 2020. The Board has declared a first quarterly interim dividend of 4.00p per share for the quarter ended 31 March 2020, paid on 26 June 2020 to shareholders on the register on 29 May 2020. Dividends are debited directly to reserves.

The Board has declared a second quarterly interim dividend of 4.00p per share for the quarter ended 30 June 2020 which will be paid on 25 September 2020 to shareholders on the register on 28 August 2020. This dividend has not been accrued in the financial statements for the six months ended 30 June 2020 as, under IFRS, interim dividends are not recognised until paid.

Dividends on equity shares paid during the period were:

8. CONSOLIDATED EARNINGS AND NET ASSET VALUE PER ORDINARY SHARETotal revenue and capital returns per share are shown below and have been calculated using the following:

There were no dilutive securities at the period end.

Since the period end, no ordinary shares have been bought back.

10. VALUATION OF FINANCIAL INSTRUMENTSFinancial assets and financial liabilities are either carried in the Consolidated Statement of Financial Position at their fair value (investment and derivatives) or at an amount which is a reasonable approximation of fair value (due from brokers, dividends and interest receivable, due to brokers, accruals, cash at bank and bank overdrafts). IFRS 13 requires the Group to classify fair value measurements using a fair value hierarchy that reflects the significance of inputs used in making the measurements. The valuation techniques used by the Group are explained in the accounting policies note 2(h), as set out in the Group’s Annual Report and Financial Statements for the year ended 31 December 2019.

Categorisation within the hierarchy has been determined on the basis of the lowest level input that is significant to the fair value measurement of the relevant asset.

The fair value hierarchy has the following levels:

Level 1 – Quoted market price for an identical instrument in an active marketA financial instrument is regarded as quoted in an active market if quoted prices are readily available from an exchange, dealer, broker, industry group, pricing service or regulatory agency and those prices represent actual and regularly occurring market transactions on an arm’s length basis. The Group does not adjust the quoted price for these instruments.

Level 2 – Valuation techniques using observable inputsThis category includes instruments valued using quoted prices for similar instruments in markets that are considered less than active, or other valuation techniques where all significant inputs are directly or indirectly observable from market data.

Valuation techniques used for non-standardised financial instruments such as options, currency swaps and other over-the-counter derivatives include the use of comparable recent arm’s length transactions, reference to other instruments that are substantially the same, discounted cash flow analysis, option pricing models and other valuation techniques commonly used by market participants making the maximum use of market inputs and relying as little as possible on entity specific inputs.

Level 3 – Valuation techniques using significant unobservable inputsThis category includes all instruments where the valuation technique includes inputs not based on market data and these inputs could have a significant impact on the instrument’s valuation.

This category also includes instruments that are valued based on quoted prices for similar instruments where significant entity determined adjustments or assumptions are required to reflect differences between the instruments and instruments for which there is no active market. The Investment Manager considers observable data to be that market data that is readily available, regularly distributed or updated, reliable and verifiable, not proprietary and provided by independent sources that are actively involved in the relevant market.

The level in the fair value hierarchy within which the fair value measurement is categorised in its entirety is determined on the basis of the lowest level input that is significant to the fair value measurement. If a fair value measurement uses observable inputs that require significant adjustment based on unobservable inputs, that measurement is a Level 3 measurement.

Assessing the significance of a particular input to the fair value measurement in its entirety requires judgement, considering factors specific to the asset or liability. The determination of what constitutes ‘observable’ inputs requires significant judgement by the Investment Manager.

Over-the-counter derivative option contracts have been classified as Level 2 investments as their valuation has been based on market observable inputs represented by the underlying quoted securities to which these contracts expose the Group.

The table below sets out fair value measurements using the IFRS 13 fair value hierarchy.

A reconciliation of fair value measurement in Level 3 is set out below.

The Level 3 investment as at 30 June 2020 in the table below relate to the OZ Minerals Brazil Royalty and, in accordance with IFRS 13, this investment was categorised as Level 3. In arriving at the fair value of these investments, the key inputs are the underlying commodity prices and illiquidity discount.

The Level 3 valuation process and techniques used by the Company are explained in the accounting policies in notes 2(h) and 2(q) on pages 87 to 89 of the Company’s Annual Report and Financial Statements for the year ended 31 December 2019 and a detailed explanation of the techniques is also available on pages 112 and 113 under “valuation process and techniques”.

Quantitative information of significant unobservable inputs – Level 3

Sensitivity analysis to significant changes in unobservable inputs within Level 3 hierarchyThe significant unobservable inputs used in the fair value measurement categorised within Level 3 of the fair value hierarchy, together with an estimated quantitative sensitivity analysis, as at 30 June 2020 are as shown below.

* The sensitivity analysis refers to a percentage amount added or deducted from the input and the effect this has on the fair value.

The sensitivity impact on fair value is calculated based on the sensitivity estimates set out by the independent valuer in its report on the valuation of contractual rights. Significant increases/(decreases) in estimated commodity prices and discount rates in isolation would result in a significantly higher/(lower) fair value measurement. Generally, a change in the assumption made for the estimated value is accompanied by a directionally similar change in the commodity prices and discount rates.

11. FINANCIAL RISKSThe Company’s investment activities expose it to the various types of risk which are associated with the financial instruments and markets in which it invests. The risks are substantially consistent with those disclosed in the previous annual financial statements with the exception of those outlined below.

Market risk arising from price riskPrice risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices (other than those arising from interest rate risk or currency risk), whether those changes are caused by factors specific to the individual financial instrument or its issuer, or factors affecting similar financial instruments traded in the market. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Company and the market price of its investments and could result in increased premiums or discounts to the Company’s net asset value.

An outbreak of an infectious respiratory illness caused by a novel coronavirus known as COVID-19 was first detected in China in December 2019 and has now developed into a global pandemic. This coronavirus has resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19 has adversely affected the economies of many nations across the entire global economy, individual issuers and capital markets, and could continue to extents that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty.

A key metric used by the BlackRock Risk and Quantitative Analysis Group to measure risk is Value-at-Risk (“VaR”) which encompasses currency, interest rate and price risk. VaR is a statistical risk measure that estimates the potential portfolio loss from adverse market movements in an ordinary market environment. VaR analysis reflects the interdependencies between risk variables, unlike a traditional sensitivity analysis.

The one-day VaR as of 30 June 2020 and 31 December 2019 based on 99% confidence level was 8.09% and 2.19%.

1 Chairman2 Chairman of the Audit & Management Engagement Committee and Senior Independent Director3 Appointed 3 February 2020

Since the period end and up to the date of this report there have been no changes in Directors’ holdings.

14. CONTINGENT LIABILITIESThere were no contingent liabilities at 30 June 2020 (six months ended 30 June 2019: nil; year ended 31 December 2019: nil).

15. PUBLICATION OF NON-STATUTORY ACCOUNTSThe financial information contained in this half yearly report does not constitute statutory accounts as defined in Section 435 of the Companies Act 2006. The financial information for the six months ended 30 June 2020 and 30 June 2019 has been reviewed by the Company’s auditors.

The information for the year ended 31 December 2019 has been extracted from the latest published audited financial statements, which have been filed with the Registrar of Companies, unless otherwise stated. The report of the auditors on those accounts contained no qualification or statement under Sections 498(2) or (3) of the Companies Act 2006.

16. ANNUAL RESULTSThe Board expects to announce the annual results for the year ending 31 December 2020, as prepared under IFRS, in February 2021.

Copies of the results announcement can be obtained from the Secretary on 020 7743 3000 or at cosec@blackrock.com. The Annual Report should be available by the beginning of March 2021, with the Annual General Meeting being held in April 2021.

17. SUBSEQUENT EVENTSSubsequent to the period end, the Company received correspondence from HMRC accepting the entitlement of the Company to make a claim for double tax relief in the relevant accounting periods in relation to underlying tax suffered on dividends from non-UK companies. This double tax relief will reduce the corporation tax liability to nil for all periods, resulting in a repayment of the corporation tax suffered in the relevant accounting periods. While the amount of the repayment has not been formally agreed with HMRC, and as such a degree of uncertainty remains, the Company now considers receipt of a repayment is sufficiently probable that it should make an accrual for accounting purposes to reflect such treatment.

The IFRS accounting rules applicable to the Company determine that an uncertain tax receivable shall be accrued in the NAV of the Company when, in the view of the Board, the successful future receipt of such receivable is probable. The Board’s current assessment is that the future receipt of the tax reclaims described above is probable and so meets this threshold.

The corporation tax refund expected to be received by the Company following HMRC’s acceptance of the claims for the relevant accounting periods amounts to £2,560,568 and has been recognised in the NAV and has been applied as revenue through the Company’s profit and loss account with effect from 18 August 2020.

The Company has also made claims, which if successful, will allow the Company to amend the group relief claims for the 2006 and 2007 periods and submit a double tax relief claim to HMRC for the full amount of corporation tax paid by the Company in respect of those years. If successful, this may result in an additional refund of £3.4 million. However, the timing and success of these claims remains uncertain, as currently HMRC is not agreeing these claims and any refund to the Company may be subject to further litigation.

INDEPENDENT REVIEW REPORT TO BLACKROCK WORLD MINING TRUST PLC

REPORT ON THE CONSOLIDATED INTERIM FINANCIAL STATEMENTSOur conclusionWe have reviewed BlackRock World Mining Trust plc’s consolidated interim financial statements (the “interim financial statements”) in the Half Yearly Financial Report of BlackRock World Mining Trust plc for the 6 month period ended 30 June 2020. Based on our review, nothing has come to our attention that causes us to believe that the interim financial statements are not prepared, in all material respects, in accordance with International Accounting Standard 34, ‘Interim Financial Reporting’, as adopted by the European Union and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom’s Financial Conduct Authority.

What we have reviewedThe interim financial statements comprise:

• the consolidated statement of financial position as at 30 June 2020;

• the consolidated statement of comprehensive income for the period then ended;

• the consolidated cash flow statement for the period then ended;

• the consolidated statement of changes in equity for the period then ended; and

• the explanatory notes to the interim financial statements.

The interim financial statements included in the Half Yearly Financial Report have been prepared in accordance with International Accounting Standard 34, ‘Interim Financial Reporting’, as adopted by the European Union and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom’s Financial Conduct Authority.

As disclosed in note 2 to the interim financial statements, the financial reporting framework that has been applied in the preparation of the full annual financial statements of the Group is applicable law and International Financial Reporting Standards (IFRSs) as adopted by the European Union.

RESPONSIBILITIES FOR THE INTERIM FINANCIAL STATEMENTS AND THE REVIEWOur responsibilities and those of the DirectorsThe Half Yearly Financial Report, including the interim financial statements, is the responsibility of, and has been approved by, the Directors. The Directors are responsible for preparing the Half Yearly Financial Report in accordance with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom’s Financial Conduct Authority.

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

What a review of interim financial statements involvesWe conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410, ‘Review of Interim Financial Information Performed by the Independent Auditor of the Entity’ issued by the Auditing Practices Board for use in the United Kingdom. A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures.

A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

We have read the other information contained in the Half Yearly Financial Report and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial statements.
