Petra Diamonds Limited

(â€œPetraâ€, â€œthe Companyâ€ or â€œthe Groupâ€)

Interim results for the six months to 31 December 2019

Petra Diamonds Limited announces its interim results (unaudited) for the six months to 31 December 2019 (â€œthe Periodâ€ or â€œH1 FY 2020â€ or â€œH1â€).

Financial

Revenue down 6% to US$193.9 million (H1 FY 2019: US$207.1 million) due to a decline in rough diamond prices.
Adjusted EBITDA³ down 11% to US$67.2 million (H1 FY 2019: US$75.6 million).
Operational free cash flow¹⁰ of US$13.7 million (H1 FY 2019: US$18.5 million), due to the decline in diamond prices.
Net loss after tax: US$10.0 million (H1 FY 2019: US$57.9 million).
Basic loss per share: 1.01 US cents (H1 FY 2019: basic loss per share of 6.57 US cents).
Net debt¹¹ of US$596.4 million (H1 FY 2019: US$559.3 million); unrestricted cash and bank facilities of US$147.3 million (H1 FY 2019: US$181.3 million). As at 31 December 2019, the Groupâ€™s SA bank facilities were undrawn.

Operations

Safety: LTIFR of 0.22 (H1 FY 2019: 0.16).
Production up 3% to 2,070,240 carats (H1 FY 2019: 2,019,147 carats).
Absolute costs remain within expectations despite inflationary pressures.
Operational Capex (excluding borrowing costs) down 35% to US$25.6 million (H1 FY 2019: US$39.3 million).

Outlook

Petraâ€™s operational delivery in H1 placed the Company on track to exceed FY 2020 production guidance of ca. 3.8 Mcts. However, the Company has had a slower start to the calendar year, particularly at Cullinan and on the back of the recent pit slump at Williamson. This will see production for H2 weighted towards Q4. The extent of further load shedding in South Africa and its resultant impact on production also remains a risk.
The Companyâ€™s first tender of H2 FY 2020 in February is in the process of being finalised; provisional results indicate that pricing on a like-for-like basis was up marginally in comparison to prices achieved in H1 FY 2020.
Project 2022 remains on track to deliver significant cash flow generation, reaching an annualised rate of US$50 â€“ 80 million. However, the operational cash flow benefits are being eroded by a weaker diamond market, due to the outbreak of the coronavirus, which has served to significantly reduce activity across the pipeline. In light of this continued market weakness, coupled with the impact of adverse product mix, the delivery of Project 2022â€™s cumulative cash flow target is expected to be delayed, resulting in the US$150 â€“ 200 million being revised to US$100 â€“ 150 million by June 2022.
The delivery of Project 2022 benefits are expected to materially contribute from FY 2021 and therefore the Company does not expect a significant change in net debt in FY 2020.
ZAR:USD exchange rate volatility continued during the Period (averaging R14.69/USD1) with some strengthening at the Period end, closing at ZAR13.99/USD1. Post Period end, the ZAR:USD exchange rate has so far been on a weaker trend.
The Companyâ€™s forecasts indicate that the Group continues to retain sufficient liquidity from existing facilities, cash resources and operating cash flows to meet its liabilities as they fall due for at least 12 months from the date of this report.
The Lender Group has re-affirmed their ongoing support of the Group and has waived the EBITDA related covenant ratios associated with its banking facilities for the December 2019 measurement period.
In light of the impact of the weakness in the diamond market on the Group's operating results and cash flow position, the Group will continue closely monitoring and managing its liquidity risk and will have further discussions with its Lender Group regarding further covenant resets and/or waivers; based on current forecasts and sensitivities, additional waivers are likely to be required for the June and December 2020 measurement periods.
The Group also continues to assess its strategic options in relation to the maturity of its US$650 million loan notes in May 2022.

Richard Duffy, CEO of Petra, commented:

â€œPetra has delivered a strong operational performance in H1 and we remain on track to achieve production guidance for the full year of ca. 3.8 million carats. Our priority now is to continue to drive operational improvements to optimise production and free cash flow, with the aim of reducing leverage levels against the backdrop of a challenging diamond market.â€

Notes:

The Group uses several non-GAAP measures above and throughout this report to focus on actual trading activity by removing certain non-cash or non-recurring items and discontinued operations. These measures include adjusted mining and processing costs, profit from mining activities, adjusted EBITDA, adjusted net profit after tax, adjusted earnings per share, adjusted US$ loan note, net debt and consolidated net debt for covenant measurement purposes. As these are non-GAAP measures, they should not be considered as replacements for IFRS measures. The Groupâ€™s definition of these non-GAAP measures may not be comparable to other similarly titled measures reported by other companies. The Board believes that such alternative measures are useful as they exclude one-off items such as the impairment charges and non-cash items to provide a clearer understanding of the underlying trading performance of the Group.

Further to the sale of Petraâ€™s interest in the Kimberley Ekapa Mining Joint Venture (â€œKEM JVâ€) and Helam Mining (â€œHelamâ€), which completed on 5 and 6 December 2018 respectively, all comparative figures in this report are stated excluding the KEM JV and Helam operations, unless otherwise specified.

Adjusted mining and processing costs are mining and processing costs stated before depreciation and share-based expense.
Profit from mining activities is revenue less adjusted mining and processing costs plus other direct income.
Adjusted EBITDA is stated before depreciation, share-based expense, net finance expense (excluding net unrealised foreign exchange gains and losses), tax expense (excluding taxation credit on impairment charge), loss / profit on discontinued operations, impairment charges and net unrealised foreign exchange gains and losses.
Adjusted net loss after tax is net loss after tax stated before losses on discontinued operations, impairment charge, taxation credit on impairment charge and net unrealised foreign exchange gains.
Impairment charge of US$1.6 million (30 June 2019: US$246.6 million and 31 December 2018: US$nil) was due to the Groupâ€™s impairment review of its operations and other receivables. Refer to note 15 for further details.
Adjusted EPS from continuing operations is stated before impairment charge, taxation credit on impairment charge and net unrealised foreign exchange gains and losses.
The loss on discontinued operations reflect the results of the KEM JV and Helam operations (net of tax), including impairment of other receivables from the KEM JV.
The US$ loan note represents the gross capital of US$650 million (30 June 2019: US$650 million and 31 December 2018; US$650 million), excluding transaction costs.
In July 2018, the Company repaid the Revolving Credit Facility (capital plus interest) of US$73.1 million and Working Capital Facility (capital plus interest) of US$33.6 million in full, however the facilities were not cancelled and remain available.
Operational free cash flow is cash generated from operations less capital expenditure for the Period as per the consolidated cash flow statement.
Net debt is the US$ loan notes and bank loans and borrowings net of cash at bank (including restricted cash).
Consolidated Net Debt for covenant measurement purposes is bank loans and borrowings plus loan notes, less cash, less diamond debtors and includes the BEE guarantees of ca. US$49.3 million (ZAR689.5 million) (30 June 2019: US$54.2 million (ZAR762.5 million) and 31 December 2018: US$72.5 million (ZAR1,039 million)) issued by Petra to the lenders as part of the BEE financing concluded in December 2014 and which are included in the Groupâ€™s balance sheet as BEE loans payable. This measure differs to the â€™Net debtâ€™ figure in the table above.
The South African lender group comprises Absa Bank Limited (acting through its Corporate and Investment Banking division), FirstRand Bank Limited (acting through its Rand Merchant Bank division), Investec Asset Management Proprietary Limited and Nedbank Limited (acting through its Corporate and Investment Banking division Trust (â€œthe Lender Groupâ€).

About Petra Diamonds Limited

Petra Diamonds is a leading independent diamond mining group and a consistent supplier of gem quality rough diamonds to the international market. The Company has a diversified portfolio incorporating interests in three underground producing mines in South Africa (Finsch, Cullinan and Koffiefontein) and one open pit producing mine in Tanzania (Williamson). Petra also conducts a limited exploration programme in Botswana and South Africa.

Petra's strategy is to focus on value rather than volume production by optimising recoveries from its high-quality asset base in order to maximise their efficiency and profitability. The Group has a significant resource base of ca. 250 million carats, which supports the potential for long-life operations.

Petra conducts all operations according to the highest ethical standards and will only operate in countries which are members of the Kimberley Process. The Company aims to generate tangible value for each of its stakeholders, thereby contributing to the socio-economic development of its host countries and supporting long-term sustainable operations to the benefit of its employees, partners and communities.

Petra is quoted with a premium listing on the Main Market of the London Stock Exchange under the ticker 'PDL' and is a constituent of the FTSE4Good Index. The Companyâ€™s US$650 million loan notes due in 2022 are listed on the Global Exchange market of the Irish Stock Exchange. For more information, visit www.petradiamonds.com.

CEOâ€™S REVIEW

Our team delivered strong operational results in H1 FY 2020, which notably saw the highest six-month level of ROM tonnes processed and carats produced by the Group to date. This strong production performance is in part being driven by the implementation of Project 2022, which has throughput as its major contributing factor. It is therefore pleasing to note the buy-in to this project across our Group and to see the positive impact it is already having on production volumes.

The major capital expansion programmes at each of our mines have for the most part been completed, as evidenced by our operational Capex declining 35% to US$25.6 million. The mines are now operating at their required steady state tonnage rates, but a major component of Project 2022 is to optimise throughput so there are a number of additional initiatives which are either being evaluated or implemented. We are seeing the benefits of such initiatives, with each mine running ahead of its full year production plan in H1. However, the Company has had a slower start to the calendar year particularly at Cullinan and on the back of the recent pit slump at Williamson. This will see production for H2 weighted towards Q4. The extent of further load shedding in South Africa and its resultant impact on production also remains a risk.

Our financial results for H1 were impacted by the weaker diamond market, with rough diamond pricing on a like-for-like basis down ca. 10% from the comparable period, and down ca. 3% versus pricing achieved in Q4 FY 2019.

The impact of lower pricing in H1 was compounded by the adverse product mix at Finsch and Williamson. Product mix is not always within our control, as diamond qualities and sizes can vary across the orebody, particularly when you are dealing with very large orebodies such as Cullinan and Williamson. However there are some mitigating actions we can take - the first is to ensure that we have access to mining from across the orebody, thereby smoothing out mix variances, and the second is to ensure that plant processes are set up to capture the value within the orebodyâ€™s production profile. In the case of Finsch, we have recovered a lower proportion of coarse diamonds (+10.8 carats) in comparison to historical averages and we have therefore made some changes in the plant in order to address this.

The implementation of Project 2022 and our emphasis on cost control saw us deliver adjusted EBITDA of US$67.2 million and positive operational free cashflow of US$13.7 million during H1 FY 2020, despite the weaker pricing environment. However, net debt increased over the Period, following the payment of the coupon on the Groupâ€™s US$650 million loan notes of US$23.6 million, the advances to the BEE partners of US$11.3 million to facilitate debt repayments, and the seasonal build-up of inventory which will be released during H2.

While the diamond market stabilised towards the end of the Period and provisional results show that pricing was up marginally at our first tender of Q3, the optimism felt towards improved market conditions has been eroded by the outbreak of the coronavirus in China and the consequent impact on consumer spending around Chinese New Year, as well as the short-term effect on diamond trading, travel and retail in these regions and further afield. Activity across the diamond pipeline is therefore expected to reduce until the virus is brought under control. We will continue to monitor the market closely and supply discipline by the major producers will remain a key factor in terms of maintaining supply / demand equilibrium.

Project 2022 remains on track to deliver significant cash flow generation, reaching an annualised rate of US$50 â€“ 80 million. However, the operational cash flow benefits are being eroded by a weaker diamond market, coupled with the impact of adverse product mix, and as a result Project 2022â€™s cumulative cash flow target is expected to be delayed, resulting in the US$150 â€“ 200 million being revised to US$100 â€“ 150 million by June 2022.

Our priority now is to continue to drive operational improvements to optimise production and free cash flow, with the aim of reducing leverage levels against the backdrop of a challenging diamond market.

SAFETY

Group LTIFR of 0.22 (H1 FY 2019: 0.16 and FY 2019: 0.21). Our primary value at Petra is â€œDo No Harmâ€, meaning safety is at the heart of everything we do. Our safety culture is backed by effective systems and processes to support our target of a zero harm working environment.

DIAMOND MARKET

While the 2019 calendar year was very challenging for the rough diamond market, Q2 FY 2020 saw growing stability in pricing as the year closed. Post Period end, demand continued to improve as the midstream looked to replenish inventory after healthy holiday season retail sales. Sales in the major US market (ca. 49% of the market) remain robust.

However, sentiment around the market has significantly weakened due to the outbreak of the coronavirus in China, which resulted in a shutdown of retail stores over the important Chinese New Year period and the subsequent postponement of the Hong Kong International Diamond, Gem and Pearl show, originally scheduled for 2 â€“ 6 March, to 18 â€“ 21 May. The virus is expected to further impact diamond trading and consumer spending in this region (ca. 14% of diamond sales) and further afield, with the end result that activity is expected to reduce across the diamond pipeline until the virus is brought under control.

Supply discipline by the major diamond producers in the second half of calendar 2019 has played an important role in moving towards more balance between supply and demand in the midstream and will remain a key factor in terms of the health of the market in calendar 2020.

Diamond Pricing

At our first tender (September 2019), diamond prices on a like-for-like basis weakened ca. 4% in comparison to Q4 FY 2019, with pricing stabilising at the October 2019 tender and showing modest improvement at the December 2019 tender, resulting in pricing being down overall ca. 3% for the Period.

Post Period end, initial pricing at our first tender in H2 FY 2020 indicates that pricing on a like-for-like basis was up marginally in comparison to H1 FY 2020. Petra will hold a total of four tenders in H2, as opposed to three in H1, as usual.

Prices achieved during H1 FY 2020 are set out in the table below:

Mine	Actual H1 FY 2020 (US$/ct)	Actual H1 FY 2019 (US$/ct)	Actual FY 2019 (US$/ct)
Cullinan	112	96	110
Finsch	79	105	99
Koffiefontein	431	447	480
Williamson	184	223	231

The poorer product mix at both Finsch and Williamson is addressed in the respective mine results commentary to follow.

FINANCIAL RESULTS

Revenue

Revenue decreased 6% to US$193.9 million in the Period (H1 FY 2019: US$207.1 million) mainly due to lower diamond prices and the previously reported adverse product mix at Finsch and Williamson, partially offset by the sale of the exceptional 20.08 carat blue diamond from Cullinan.

Mining and processing costs

The mining and processing costs for H1 FY 2020 are comprised of on-mine cash costs as well as other operational expenses. A breakdown of the total mining and processing costs for the Period is set out below.

	On-mine cash costs¹ US$m	Diamond royalties US$m	Diamond inventory and stockpile movement US$m	Group technical, support and marketing costs² US$m	Adjusted mining and processing costs US$m	Depreciation³ US$m	Total mining and processing costs (IFRS) US$m
H1 FY 2020	135.1	4.8	(25.6)	9.3	123.6	46.7	170.2
H1 FY 2019	135.5	7.3	(27.1)	11.4	127.2	50.4	177.7
FY 2019	266.9	13.2	(2.9)	24.5	301.7	105.9	407.6

Notes:

Includes all direct cash operating expenditure at operational level, i.e. labour, contractors, consumables, utilities and on-mine overheads.
Certain technical, support and marketing activities are conducted on a centralised basis.
Excludes exploration and corporate / administration.

Absolute on-mine cash costs in H1 FY 2020 were largely flat compared to H1 FY 2019 (in line with expectations), despite ongoing inflationary pressures, due to:

inflationary increases, including the impact of electricity and labour costs (ca. 5% increase);

offset by:

the effect of translating ZAR denominated costs at the South African operations at a weaker ZAR/USD average exchange rate (ca. 4% decrease); and
a reduction in the treatment of Finsch overburden dumps lowering operating costs (ca. 1% decrease).

Royalties decreased to US$4.8 million (H1 FY 2019: US$7.3 million) due to lower profit net of capex at Finsch, as defined in the royalty legislation of South Africa.

Profit from mining activities

Profit from mining activities decreased 12% to US$70.6 million (H1 FY 2019: US$80.1 million), mainly due to lower diamond pricing and therefore revenue.

Exploration

Petra incurred US$0.2 million of exploration expenditure during the Period (H1 FY 2019: US$0.2 million).

Corporate overhead â€“ General and Administration

Corporate overhead (before depreciation and share based payments) decreased 26% to US$3.2 million for the Period (H1 FY 2019: US$4.3 million), mainly attributable to control over corporate expenditure, accounting adjustment for leases under IFRS 16 and benefitting from the ZAR weakening against the US Dollar.

Adjusted EBITDA

Adjusted EBITDA, being profit from mining activities less exploration and corporate overhead, decreased 11% to US$67.2 million (H1 FY 2019: US$75.6 million), representing an adjusted EBITDA margin of 35% (H1 FY 2019: 36%), driven by lower revenue partially offset by decreased mining and processing costs.

Depreciation

Depreciation for the Period decreased to US$47.0 million (H1 FY 2019: US$50.8 million), mainly due a lower asset base as a result of prior period impairments of operational assets and the weakening of the ZAR against the US Dollar.

Impairment charge

Impairment reviews carried out at Cullinan, Finsch, Koffiefontein and Williamson operational assets did not result in an impairment charge during the Period. An impairment review of the Groupâ€™s other receivables during the Period resulted in a net impairment charge US$1.6 million comprising of the Williamson VAT receivable of US$1.7 million and recoupment of US$0.1 million previously impaired in respect of the KEM JV receivable (H1 FY 2019: US$nil).

Loss on discontinued operations â€“ KEM JV and Helam

There were no disposals during the current Period under review. During H1 FY 2019, the loss on discontinued operations related to the Groupâ€™s disposal of its interests in the KEM JV and Helam operations in December 2018.

Net financial expense

Net financial expense of US$31.4 million (H1 FY 2019: US$45.4 million) comprises:

net unrealised foreign exchange gains of US$2.7 million (H1 FY 2019: US$13.7 million loss) representing (i) the unrealised foreign exchange gains on the foreign currency retranslation of cross border loans considered to be repayable in the foreseeable future, (ii) unrealised losses on forward exchange contracts (refer to note 6 for further detail); and
interest received on bank deposits of US$0.1 million (H1 FY 2019: US$0.4 million);

offset by:

interest on the Groupâ€™s debt and working capital facilities of US$25.4 million (H1 FY 2019: US$20.5 million) stated after the capitalisation of interest of US$nil (H1 FY 2019: US$3.7 million) associated with the funding of assets under development (interest is no longer capitalised as the Groupâ€™s expansion programmes have been commissioned);
net interest payable on the BEE partner loans and amortisation of lease liabilities in accordance with IFRS 16 of US$3.2 million (H1 FY 2019: US$4.9 million);
a charge for the unwinding of the present value adjustment for Group rehabilitation costs of US$1.7 million (H1 FY 2019: US$3.9 million); and
net realised foreign exchange loss on settlement of forward exchange contracts of US$3.4 million (H1 FY 2019: US$2.8 million).

Tax credit / charge

The tax credit of US$3.2 million (H1 FY 2019: US$2.5 million) comprised a deferred tax credit of US$3.2 million (H1 FY 2019: US$7.6 million charge), with an income tax charge of US$nil for the Period (H1 FY 2019: US$5.1 million charge due to taxable profits generated at Finsch).

Group loss / profit

The Groupâ€™s net loss after tax is US$10.0 million (H1 FY 2019: US$57.9 million).

Earnings per share

Basic loss per share from continuing operations of 1.01 US$ cents was recorded (H1 FY 2019: 6.57 US$ cents).

Adjusted loss per share from continuing operations (adjusted for impairment charges and net unrealised foreign exchange gains and losses) of 1.17 US$ cents was recorded (H1 FY 2019: 0.16 US$ cents (adjusted for impairment charges, taxation credit on impairment charge, net unrealised foreign exchange gains and losses, and loss on discontinued operations)).

Operational free cash flow

During the Period and considering the weaker diamond market, generation of operational free cash flow of US$13.7 million (H1 FY 2019: US$18.5 million outflow) reflects the positive benefits of our capital investment and the initial results from Project 2022 to optimise production and drive cost efficiencies. This positive cash flow was offset by:

US$27.9 million (H1 FY 2019: US$23.5 million) cash finance expenses net of finance income and realised foreign exchange gains and losses;
US$11.3 million (H1 FY 2019: US$21.2 million) advances to BEE partners, largely related to servicing of BEE bank debt in line with the Groupâ€™s stated intention of reducing consolidated net debt for covenant measurement purposes (which includes BEE banking facilities), with the advances recoverable against future BEE partner distributions; and
US$nil (H1 FY 2019: US$9.1 million) net advances and payments to KEM JV.

Cash and Diamond Debtors

As at 31 December 2019, Petra had cash at bank of US$53.6 million (H1 FY 2019: US$90.7 million). Of these cash balances, US$40.1 million was held as unrestricted cash (H1 FY 2019: US$76.8 million), US$12.6 million was held by Petraâ€™s reinsurers as security deposits on the Groupâ€™s cell captive insurance structure (with regards to the Groupâ€™s environmental guarantees) (H1 FY 2019: US$13.0 million) and US$0.9 million was held by Petraâ€™s bankers as security for other environmental rehabilitation bonds lodged with the Department of Mineral Resources and Energy in South Africa (H1 FY 2019: US$0.9 million).

Diamond debtors at 31 December 2019 were US$12.8 million (H1 FY 2019: US$4.4 million).

Loans and Borrowings

The Group had loans and borrowings (measured under IFRS) at Period end of US$652.1 million (H1 FY 2019: US$649.5 million), comprised of the loan notes plus accrued interest of US$652.1 million (H1 FY 2019: US$649.5 million). Bank debt facilities undrawn and available to the Group at 31 December 2019 were US$107.2 million (H1 FY 2019: US$104.5 million).

The Group continues to assess its strategic options in relation to the maturity of its US$650 million loan notes in May 2022.

Net debt at 31 December 2019 was US$596.4 million (H1 FY 2019: US$559.3 million).

Covenant Measurements attached to banking facilities

The Companyâ€™s EBITDA related covenants associated with its banking facilities are as outlined below:

	12 months to 31 Dec 2019	12 months to 30 Jun 2020	12 months to 31 Dec 2020	12 months to 30 Jun 2021
Consolidated Net Debt to Consolidated EBITDA:
- Covenant ratio:	? 4.25x	? 3.5x	? 3.25x	? 3.0x
Consolidated EBITDA to Consolidated Net Finance Charges:
- Covenant ratio:	? 2.5x	? 2.75x	? 3.0x	? 3.25x
Consolidated Net Senior Debt to Book Equity:
- Covenant ratio	?0.4x	?0.4x	?0.4x	?0.4x

The impact of the recent weakness in the diamond market on the Groupâ€™s operating results and cash flow position has been discussed with the Lender Group, including possible breaches in its EBITDA-related covenants for the December 2019 (measured in March 2020), e June 2020 and December 2020 reporting periods. The Lender Group has re-affirmed their ongoing support of the Group and has waived the EBITDA related covenant ratios associated with its banking facilities for the December 2019 measurement period (measured in March 2020).

The Group closely monitors and manages its liquidity risk, and cash forecasts are regularly produced and run for different scenarios, indicating that the Group has sufficient cash reserves and banking facilities to meet its working capital and capital development requirements under its forecasts for at least the next 18 months, including sensitivities.

BEE loans receivable and payable

BEE loans receivable of US$125.9 million (H1 FY 2019: US$79.0 million) relate to the Groupâ€™s BEE partnersâ€™ financing of their interests in the Koffiefontein mine, advances provided to the BEE partners to enable the BEE partners to discharge interest and capital commitments under the BEE Lender facilities (refer to the information below regarding the guarantee provided by the Company) and other advances to the BEE partners which have enabled the Itumeleng Petra Diamonds Employee Trust (â€œIPDETâ€) to make distributions to their beneficiaries (Petra Directors and Senior Managers do not qualify as beneficiaries under the IPDET Deed). During the Period, Petra advanced US$9.3 million (H1 FY 2019: US$18.3 million) to facilitate the servicing of capital and interest payments on behalf of the BEE Partners and US$2.0 million (H1 FY 2019: US$2.9 million) for distributions to the beneficiaries of the IPDET and shareholders of Kago.

The BEE loans payable of US$128.1 million (H1 FY 2019: US$112.4 million) relate to the initial acquisition loan funding advanced by the Groupâ€™s BEE partners to the operations to acquire their investments in Finsch and Cullinan. The repayment of these loans by the mines to the BEE partners will be from future free cash flows generated by the mining operations.

Refer to note 12 for further detail on BEE loans receivable and payable.

Other Liabilities

Other than trade and other payables of US$46.3 million (comprising US$23.4 million trade creditors, US$22.2 million employee related accruals and US$0.7 million other payables) (H1 FY 2019: US$72.1 million), the remaining liabilities on the balance sheet mainly comprise provisions for rehabilitation liabilities, post retirement employee related provisions and deferred tax.

Capex

Total Group Capex for the Period reduced to US$26.5 million (H1 FY 2019: US$44.3 million), comprising:

US$15.9 million expansion Capex (H1 FY 2019: US$28.5 million);
US$10.6 million sustaining Capex (H1 FY 2019: US$12.1 million); and
US$nil capitalised borrowing costs with regards to the expansion Capex (H1 FY 2019: US$3.7 million).

Note:

The Company is not able to precisely measure the ROM / tailings grade split because ore from both sources is processed through the same plant; the Company therefore back-calculates the grade with reference to resource grades.

Production:

Cullinanâ€™s overall carat production increased by 7% to 889,787 carats (H1 FY 2019: 832,026 carats) due to ROM production increasing by 9% to 855,371 carats (H1 FY 2019: 785,444 carats). The higher ROM production was largely driven by an increased volume treated of 2,295,197 tonnes (H1 FY 2019: 1,996,624 tonnes), with the ROM grade of 37.3 cpht marginally lower than guidance of 38 â€“ 42 cpht.

Tailings production decreased by 26% to 34,416 carats in line with the mine plan (H1 FY 2019: 46,582 carats).

Sales:

Cullinanâ€™s revenue increased 23% to US$81.7 million (H1 FY 2019: US$66.2 million), due to the higher production and sales volumes, as well as the sale of the exceptional 20.08 carat Type IIb blue diamond for US$14.9 million (H1 FY 2019: US$nil exceptional diamond sales).

Costs:

The on-mine unit cash cost per total tonne treated was up 17% to ZAR262 (H1 FY 2019: ZAR224), mainly due to the increase in more costly ROM tonnes treated during the period, in line with plans to reduce tailings throughput.

Capex:

Cullinanâ€™s Capex for FY 2020 is weighted to H1, with US$12.0 million spent (H1 FY 2019: US$22.8 million) on the installation of the remaining drawpoints in the C-Cut. The Company expects Cullinanâ€™s full year Capex to remain in line with guidance.

Note:

The Company is not able to precisely measure the ROM / tailings grade split because ore from both sources is processed through the same plant; the Company therefore back-calculates the grade with reference to resource grades.

Production:

Finschâ€™s overall carat production decreased 4% to 913,557 carats (H1 FY 2019: 947,424 carats) due to ROM carat production decreasing 5% to 880,707 carats (H1 FY 2019: 927,934 carats) and tailings carat production delivering 32,850 carats (H1 FY 2019: 19,490 carats).

The contribution from Block 5 SLC to the ROM carat production increased by 14% to 870,567 carats (H1 FY 2019: 763,913 carats) whilst the contribution from the high grade and higher value ROM overburden dumps reduced to 9,484 carats (H1 FY 2019: 159,738 carats). The higher carat contribution from Block 5 SLC was largely driven by an increased volume treated of 1,498,811 tonnes (H1 FY 2019: 1,168,702 tonnes). The ROM grade of 57.4 cpht (H1 FY 2019: 61.7 cpht) marginally exceeded guidance of 54 â€“ 57 cpht.

Sales:

Sales decreased 29% to US$61.7 million (H1 FY 2019: US$87.0 million), mainly due to the average value per carat decreasing 25% to US$79 (H1 FY 2019: US$105). Poorer product mix at Finsch is due to the depletion of the higher value overburden dumps, as well as fewer and poorer quality large diamonds recovered compared to historical averages. In order to help us to better understand and prioritise an improved product mix, all of the coarse diamond X-ray machines in the plant were upgraded to increase the probability of the recovery of high value large stones. The X-ray machines in the bulk sample plant were replaced with newer technology X-ray machines and are now being used to treat recovery tailings from the main plant to provide additional assurance around the efficiency of the recovery circuit.

Costs:

The on-mine unit cash cost per total tonne treated remained largely flat at ZAR405 (H1 FY 2019: ZAR400).

Capex:

Capex of US$5.6 million for the Period (H1 FY 2019: US$13.8 million) lower due to the SLC expansion programme reaching completion.

Production:

Koffiefonteinâ€™s overall production continued its improving trend with ROM production up 76% to 44,545 carats (H1 FY 2019: 25,275 carats). ROM tonnes treated improved by 49% to 561,296 tonnes (H1 FY 2019: 377,391 tonnes).

Sales:

Koffiefonteinâ€™s revenue increased 40% to US$14.7 million (H1 FY 2019: US$10.5 million), due to the significant lift in production, offset by the weaker diamond market.

Costs:

The unit cash cost per total tonne treated was down 28% to ZAR419 (H1 FY 2019: ZAR585), mainly due to the increase in ROM tonnes treated during the Period and the effect of increased volumes on the large fixed cost base.

Capex:

Capex decreased 28% to US$2.3 million (H1 FY 2019: US$3.2 million) in line with the operation approaching steady state production.

Production:

Williamsonâ€™s ROM production increased 3% to 214,888 carats (H1 FY 2019: 208,064 carats), demonstrating the continued steady operational delivery of the mine.

On 21 January 2020, a pit slump of approximately 1.3 million tonnes occurred at Williamson in an area on the south western sector of the pit. Most importantly, nobody was harmed in the incident. There was also no damage to any mining equipment. After a preliminary risk assessment, all activities in the vicinity of the slumped area have been stopped and the local mine team is developing a mitigation plan, however the situation is made more challenging by the high seasonal rainfall currently being experienced.

Production was moved to areas in the north west of the pit that can be accessed and mined safely. However, the area affected includes a pit access haulage road as well as a mining area and therefore needs to be cleared and stabilised, with new appropriate infrastructure for pit access re-established, in order to ensure that this does not materially impact future production. In the short term, the slump will have a negative impact on grade and carats, particularly in February and March 2020. However, as Williamson was running ahead of its mine plan for the full year, we are maintaining our targeted tonnes treated and carats recovered.

Sales:

Williamsonâ€™s revenue decreased 17% to US$43.5 million (H1 FY 2018: US$18.5 million), mainly due to the average value per carat being down 17% to US$184 (H1 FY 2018: US$223). The poorer product mix at Williamson is due to the area of the orebody where mining is taking place.

The Company remains in discussions with the Government of Tanzania and local advisers in relation to various issues, including the overdue VAT receivables and the blocked parcel.

Costs:

The on-mine unit cash cost per total tonne treated was down 12% to US$10.2 (H1 FY 2019: US$11.6), which remains in line with guidance.

Capex:

Capex of US$5.7 million (H1 FY 2019: US$3.2 million) related to sustaining Capex only and primarily related to inpit waste stripping, tailings line expansion and improvements to the slimes dam walls. All capex is funded from the mineâ€™s own cashflow and may be adjusted when issues relating to the blocked parcel and VAT are resolved.

The recent pit slump may accelerate the removal of overburden waste material from the pit, which may increase the short to medium term Capex requirements for the mine. Once the Company has completed its technical assessment and mitigation plan, further information will be made available.

BOARD SUCCESSION

As previously announced, Peter Hill CBE will succeed Adonis Pouroulis as Non-executive Chairman with effect from 31 March 2020.

As part of the long term succession planning, Varda Shine will become Chair of the Remuneration Committee with effect from 31 March 2020, in succession to Gordon Hamilton.

Dr Pat Bartlett, Non-executive Director, has notified the Board that he wishes to retire from the Board, after nearly nine yearsâ€™ service, on 30 June 2020.

Mr Tony Lowrie, Senior Independent Director, has informed the Board that he wishes to retire from the Board at the end of the Annual General Meeting (â€œAGMâ€) in November 2020, after more than eight yearsâ€™ service, and thus will not be offering himself for re-election at the AGM. An announcement regarding his replacement as Senior Independent Director will be made in due course.

PRINCIPAL BUSINESS RISKS

The Group is exposed to a number of risks and uncertainties which could have a material impact on its long-term development, and performance and management of these risks is an integral part of the management of the Group.

An overview of the key risks which could affect the Groupâ€™s operational and financial performance was included in the Companyâ€™s 2019 Annual Report, which can be accessed at www.petradiamonds.com. These may impact the Group over the medium to long term; however, the following key risks have been identified which may impact the Group over the next six months.

Short term demand and prices

The stability of financial markets and the corresponding effect on consumer demand impacts the Group and the diamond industry as a whole. Whilst the medium to long term fundamentals of the diamond market remain intact, with demand forecast to outpace supply, in the short term the prevailing climate of global economic uncertainty, exacerbated by the outbreak of the Coronavirus in China, may cause some volatility in rough diamond pricing.

Although diamond prices are influenced by numerous factors beyond the Companyâ€™s control, the Groupâ€™s management closely monitors developments in the international diamond market (across the pipeline from the rough market to the retail consumer market) to be in a position to react in a timely manner to changes in rough diamond prices and demand.

Product mix variability

Some level of variability in terms of product mix is associated with large and complex orebodies like Cullinan and Williamson, where the recovery of high value stones varies on a period-to-period basis. Variability is also being experienced in the product mix at Finsch, which contains a lower than expected incidence of gem-quality coarse (larger) diamonds in comparison to historical recoveries. This risk can be addressed by maximising tonnages across the footprint of the orebodies and by optimising plant processes to capture the value within the individual kimberliteâ€™s product profile. However, in the case of Cullinan, it is impossible to predict when exceptional diamonds (valued at +US$5 million) will be recovered as they are truly rare.

Variability in overall diamond prices realised as a result of this product mix volatility may have an impact on the Groupâ€™s financial performance.

Financing and liquidity

The Group closely monitors and manages its liquidity risk. Cash forecasts are regularly produced and sensitivities run for different scenarios including, but not limited to, changes in rough diamond prices, product mix and foreign exchange rates, different production rates from the Groupâ€™s producing assets and delays to development projects.

The Groupâ€™s forecast, taking into account the risks described above and the covenants as discussed in the â€˜Covenant measurements attached to banking facilitiesâ€™ section of the Financial Review, show that the Group will be able to operate within its current debt facilities and have sufficient liquidity headroom for at least the next 12 months, although headroom remains sensitive to diamond prices, foreign exchange rates and production. There remains a risk, given these factors and the impact on operating cashflows, that the Groupâ€™s liquidity position could deteriorate and the resulting lack of adequate available cashflows, potential breach of covenants and restricted access to its debt facilities could impact development work and impact the operations. The Group will therefore have further discussions with its Lender Group regarding further covenant resets and/or waivers as required.

In addition, the Group's US$650 million loan notes reach maturity in May 2022 and there is a risk that the Group will be unable to refinance or repay these loan notes when due. The Company therefore continues to assess its strategic options in relation to the maturity of these loan notes.

Exchange rates

With Petraâ€™s operations mainly in South Africa, but diamond sales based in US Dollars, the volatility and movement in the Rand is a significant factor to the Group. The Group also undertakes transactions in a number of different currencies, including Tanzanian Shillings, GBP and Euro. Fluctuations in these currencies can have an impact on the Groupâ€™s performance, albeit less significant than the impact of fluctuations in the ZAR/USD exchange rate.

In order to mitigate currency risk, the Group continually monitors the movement of the Rand against the US Dollar, the maturity dates and the level of the hedge book and takes expert advice from its bankers in this regard. It is the Groupâ€™s policy to hedge, on a short term basis, linked to the tender calendar, a portion of US Dollar sales revenue when weakness in the Rand deems it appropriate.

Country and political risk

Petraâ€™s operations are predominantly based in South Africa, with lesser exposure to Tanzania. Emerging market economies could be subject to greater risks, including legal, regulatory, taxation, economic, and political risks, and are potentially subject to rapid change.

Petra is in ongoing dialogue with the Government of Tanzania and local advisers in relation to various issues, including the overdue VAT receivables and the blocked parcel. In addition, there is no certainty with regards to the outcome for the blocked Williamson parcel, which remains in the custody of the Government of the United Republic of Tanzania. The long-term viability of the Companyâ€™s Williamson operations is dependent on the successful completion of the ongoing negotiations with the Government of Tanzania.

Labour relations

The Groupâ€™s production is dependent on a stable and productive labour workforce. The mining labour relations environment in South Africa has been notably volatile over the years, but much less so specifically in the diamond sector, where there is a higher incidence of mechanisation and skilled workers, leading to smaller and more manageable workforces which do not rely on migrant labour.

Petraâ€™s three-year wage agreement with the National Union of Mineworkers comes to an end on 30 June 2020, with negotiations for the period post June 2020 to commence during Q4 FY 2020. While there is the potential for labour disruption around the time of the new wage negotiation, it is encouraging to note that the labour relations environment in the country as a whole has been much less volatile over the last year, with a settlement reached relatively quickly for the platinum sector in 2019. Petra remains highly focused on managing labour relations and on maintaining open and effective communication channels with its employees and the appropriate union representatives at its operations.

Power supply

South Africaâ€™s power issues have been well publicised. Eskomâ€™s approach is to consult with industry before implementing load shedding, with advanced notice giving customers time to react appropriately. Petra is used to managing the operations optimally to maintain production levels as much as possible throughout load shedding requests. Such measures include the bringing forward of essential maintenance work and restricting load curtailment to processing plants where possible, given the Companyâ€™s operations have excess processing capacity which allows for additional throughput when full power is restored. However, the impact of load shedding on the Company will depend on the duration and level of severity of the power restriction.

NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

FOR THE SIX MONTH PERIOD ENDED 31 DECEMBER 2019

1. GENERAL INFORMATION

Petra Diamonds Limited (the â€œCompanyâ€), a limited liability company listed on the Main Market of the London Stock Exchange, is registered in Bermuda with its Group management office domiciled in the United Kingdom. The Consolidated Interim Financial Statements of the Company for the six month period ended 31 December 2019 comprise the Company and its subsidiaries, joint operations and associates (together referred to as the â€œGroupâ€).

2. ACCOUNTING POLICIES

The interim results, which are unaudited, have been prepared in accordance with the requirements of International Accounting Standard 34. This condensed interim report does not include all the notes of the type normally included in an annual financial report. This condensed report is to be read in conjunction with the Annual Report for the year ended 30 June 2019, and any public announcements made by the Group during the interim reporting period. The annual financial report for the year ended 30 June 2019 was prepared in accordance with International Financial Reporting Standards as adopted by the European Union (â€œIFRSâ€™sâ€) and the accounting policies applied in this condensed interim report are consistent with the polices applied in the annual financial report for the year ended 30 June 2019 unless otherwise noted.

The company has adopted IFRS 16 Leases in the Period, following the standard becoming effective for accounting periods commencing on or after 1 January 2019.

IFRS 16 Leases

The Group is required to apply IFRS 16 for annual reporting periods beginning on or after 1 January 2019. IFRS 16 provides a single lessee accounting model, requiring the recognition of assets and liabilities for all leases, together with options to exclude leases where the lease term is 12 months or less, or where the underlying asset is of low value. The Group adopted IFRS 16 using the modified retrospective approach, with recognition of transitional adjustments on the date of initial application (1 January 2019), without restatement of comparative figures.

IFRS 16 provides for certain optional practical expedients, including those related to the initial adoption of the standard. The Group applied the following practical exceptions when applying IFRS 16 to leases previously classified as operating leases under IAS 17:

â€¢ apply a single discount rate to a portfolio of leases with reasonably similar characteristics;

â€¢ exclude initial direct costs from the measurement of right-of-use assets at the date of initial application;

â€¢ reliance on previous assessments on whether leases are onerous as opposed to preparing an impairment review under IAS 36 as at the date of initial application; and

â€¢ apply the exemption not to recognise right-of-use assets and liabilities for leases with less than 12 months of lease term remaining as of the date of initial application.

As a lessee, the Group previously classified leases as operating or finance leases based on its assessment of whether the lease transferred substantially all of the risks and rewards of ownership. Under IFRS 16, the Group recognises right-of-use assets and lease liabilities for most leases. However, the Group has elected not to recognise right-of-use assets and lease liabilities for some leases of low value assets based on the value of the underlying asset when new or for short-term leases with a lease term of 12 months or less.

On adoption of IFRS 16, the Group recognised right-of-use assets and lease liabilities in relation to leases of office space, mining equipment and contract mining services, which had previously been classified as operating leases.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the Groupâ€™s incremental borrowing rate as at 1 January 2019. The Groupâ€™s incremental borrowing rate is the rate at which a similar borrowing could be obtained from an independent creditor under comparable terms and conditions.

The right-of-use assets were measured at an amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments.

Included in profit or loss for the period are US$2.4 million of amortisation of right-of-use assets and US$0.4 million of finance expense on lease liabilities.Below is a summary of the impact upon adoption of IFRS 16 â€œLeasesâ€.

US$ million
Right-of-use asset â€“ 1 July 2019	9.5
Lease liability â€“ 1 July 2019	(9.5)
Effect on retained earnings â€“ 1 July 2019	â€”

31 December 2019:
Lease payments	2.8
Amortisation of right-of-use asset	2.4
Finance charges to income statement on lease liability	0.4

The key judgements and assumptions around leases are disclosed under the section â€˜Significant assumptions and Judgementsâ€™.

Basis of preparation including going concern

Background

Production results for the Period exceeded management expectations. However, product mix and rough diamond market conditions negatively impacted rough diamond pricing and, as a result, revenue and cash flow results. As a result of the above, revenue for the Period decreased 6% compared to H1 FY 2019. Product mix results are discussed in more detail in the mine-by-mine commentary in the Operational Review section above, while the rough diamond market is discussed in the Diamond Market section above.

The Companyâ€™s covenants related to its South African banking facilities are as outlined below:

	12 months to 31 Dec 2019	12 months to 30 Jun 2020	12 months to 31 Dec 2020	12 months to 30 Jun 2021
Consolidated Net Debt to Consolidated EBITDA:
Required covenant ratio:	? 4.25x	? 3.5x	? 3.25x	? 3.0x
Consolidated EBITDA to Consolidated Net Finance Charges:
Required covenant ratio:	? 2.5x	? 2.75x	? 3.0x	? 3.25x
Consolidated Net Senior Debt to Book Equity
Required covenant ratio:	? 0.4x	? 0.4x	? 0.4x	? 0.4x

The implementation of Project 2022, as announced in July 2019, aims to identify and drive efficiencies and improvements across all aspects of the business. Project 2022â€™s focus is on enhancing cashflow generation and reducing net debt. The increase in production for the Period is mainly as result of certain initiatives identified through Project 2022 starting to deliver. In light of the continued weakness in the diamond market, coupled with the impact of adverse product mix, the delivery of Project 2022â€™s cumulative cash flow target is expected to be delayed, resulting in the US$150 â€“ 200 million being revised to US$100 â€“ 150 million by June 2022, to achieve annualised cash flow generation of US$50 â€“ 80 million.

Forecasts and associated risks

In light of the above, coupled with recent market commentary about continued weakness in the diamond market, the following have been key considerations for the Board in assessing the Groupâ€™s ability to operate as a going concern at the date of this Report:

risks of further market weakness reducing diamond prices;
the impact on pricing due to product mix volatility;
risks of general production disruptions;
risks of increased operating costs;
volatility in the South African Rand; and
the impact of reduced revenue on earnings, cash flow projections and associated covenant measurements.

Base case forecasts (which incorporate current diamond market conditions) assume an average exchange rate of ZAR14.50:US$1, continued advances to BEE partners to enable them to meet their loan obligations to the BEE Lenders, and specifically excludes the proceeds from the sale of exceptional stones, the sale of the blocked Williamson parcel and the recovery of historical and current VAT during the forecast period.

The Board has reviewed the Groupâ€™s forecasts and sensitivities for a period of at least 12 months from the date of this report, including both forecast liquidity and covenants. In doing so, careful consideration was given to potential risks to the forecasts as listed above.

Under the base case, and cases adjusted for sensitivities on an individual basis, the Companyâ€™s forecasted liquidity is likely to require temporary utilisation of the South African banking facilities should the ongoing weakness in the diamond market persist during the period under review, and therefore the Groupâ€™s base case forecasts are anticipated to be dependent upon the continued availability of the South African banking facilities. The impact of the recent weakness in the diamond market on the Groupâ€™s operating results and cash flow position has been discussed with the Lender Group, including likely breaches of its EBITDA-related covenants for the December 2019 (measured in March 2020), June 2020 and December 2020 reporting periods. The Lender Group have re-affirmed their ongoing support of the Group and the Company and have waived the EBITDA related covenant ratios associated with its banking facilities for the December 2019 measurement period (measured in March 2020).

The Company and the Lender Group will hold further discussions with regards to covenants for the June 2020 reporting period in H2 FY 2020 following completion of at least two of the four tenders to be held during H2 FY 2020 to gauge short term rough diamond prices, and resultant forward looking full year results and cash flow projections. This may include covenant resets and/or waivers for the June 2020 measurement period and potentially for subsequent measurement periods. All future covenant waivers or resets will be subject to the approval from respective credit committees of the Lender Group and, although the Company recognises the ongoing support from the Lender Group and the track record of achieving waivers or resets historically, there is no guarantee that future waivers or resets will be received.

Conclusion

The Board is of the view that the longer term fundamentals of the diamond market remain sound notwithstanding the current weakness in the pricing of rough diamonds. The forecast benefits of Project 2022 are expected to optimise production and maximise cash flow, while having access to some of the largest diamond resources globally will continue to provide organic growth opportunities well beyond 2030.

The Board recognises the significant debt levels within the Group and despite the operations now delivering production results in line with guidance, with all major capital expansion programmes having been delivered on, the current weakness in the diamond market has heightened the need to continue to optimise production and associated cash margins across all operations by continually focusing on key deliverables as currently envisaged to be addressed via Project 2022.

Ongoing engagement with the Lender Group is key to ensuring facilities remain available to the Group. Cash management and preservation will continue to be of the highest importance via the management of working capital, specifically diamond inventory control, deferring of non-essential cash payments, maintaining very tight control over costs and overheads, and deferral of certain elements of its capital expenditure that are not essential.

Considering the recent positive engagements with the Lender Group, alongside the Groupâ€™s existing cash resources and the expected continuing availability of current facilities, the Board assessed the liquidity headroom to be adequate under the Groupâ€™s current base case and reasonable sensitivities.

Accordingly, the Board has concluded that the going concern basis in the preparation of the unaudited interim financial statements remains appropriate and that there are no material uncertainties that would cast doubt on that basis of preparation.

New standards and interpretations applied

The IASB has issued IFRS 16 Leases with an effective date on or after1 January 2019 which is the only standard to impact on the Group during the Period under review.

Refer to Accounting Polices above.

New standards and interpretations not yet effective

Certain new standards, amendments and interpretations to existing standards have been published that are mandatory for the Groupâ€™s accounting periods beginning after 1 July 2020 or later periods, none of which are anticipated to be significant or relevant to the Group.

Significant assumptions and judgements:

The preparation of the condensed consolidated interim financial statements requires management to make estimates and judgements and form assumptions that affect the reported amounts of the assets and liabilities, reported revenue and costs during the periods presented therein, and the disclosure of contingent liabilities at the date of the interim financial statements. Estimates and judgements are continually evaluated and based on managementâ€™s historical experience and other factors, including future expectations and events that are believed to be reasonable. The estimates and assumptions that have a significant risk of causing a material adjustment to the financial results of the Group in future reporting periods are discussed below.

Key estimates and judgements:

Impairment reviews

The Group prepares impairment models and assesses mining assets for impairment or reversals of previous impairments. While conducting an impairment test of its assets using recoverable values using the current life of mine plans, the Group exercised judgement in making assumptions about future rough diamond prices, foreign exchange rates, volumes of production, ore reserves and resources included in the current life of mine plans, future development and production costs and factors such as inflation and discount rates. Changes in estimates used can result in significant changes to the â€˜Consolidated Income Statementâ€™ and â€˜Statement of Financial Positionâ€™.

Cullinan, Finsch, Koffiefontein and Williamson

The impairment tests for Cullinan, Finsch, Koffiefontein and Williamson resulted in the recognition of an impairment charge of US$nil (30 June 2019: US$223.7 million and 31 December 2018: US$nil) on a carrying value of property, plant and equipment of US$950.3 million (30 June 2019: US$1,187.5 million and 31 December 2018: US$1,188.3). For further details of the inputs, assumptions and sensitivities in the impairment model, refer to note 15.

KEM JV

Refer to note 16 for disposal and impairment reviews in the prior periods.

Recoverability of diamond parcel in Tanzania

The Group holds diamond inventory valued at lower of cost and net realisable value of US$12.3 million (30 June 2019: US$12.4 million and 31 December 2018: US$12.4 million) in the Statement of Financial Position in respect of the Williamson mineâ€™s confiscated diamond parcel. During FY 2018, an investigation into the Tanzanian diamond sector by a parliamentary committee in Tanzania was undertaken to determine if diamond royalty payments were being understated. In connection with this, Petra announced on 11 September 2017 that a parcel of diamonds (71,654.45 carats) from the Williamson mine in Tanzania (owned 75% by Petra and 25% by the Government of the United Republic of Tanzania (â€œGoTâ€)) had been blocked for export to Petraâ€™s marketing office in Antwerp.

The assessment of the recoverability of the diamond parcel required significant judgement. In making such a judgement, the Group considered their ongoing discussions with the GoT, confirmation was received from the GoT in FY 2018 that they held the diamond parcel of 71,654.45 carats, verbal re-confirmation has been given this year in the course of the ongoing discussions held with the GoT, an assessment of the internal process used for the sale and export of diamonds confirming such process is in full compliance with legislation in Tanzania and the Kimberley Process, and legal advice received from the Groupâ€™s in-country attorneys which supports the Groupâ€™s position.

During FY 2018, Petra received authorisation from the GoT to resume diamond exports and sales from Williamson and all subsequent parcels of diamonds have been exported from Tanzania for sale at the Companyâ€™s marketing office in Antwerp. While a resolution has not yet been reached with regards to the parcel of diamonds that was blocked from export, based on the above judgements and assessment thereof, management remain confident that the diamond parcel will be released by the GoT and will be available for future sale.

Recoverability of VAT in Tanzania

The Group has gross VAT receivables of US$38.0 million (30 June 2019: US$32.9 million and 31 December 2018: US$25.0 million) in respect of the Williamson mine, all of which are past due and have therefore been classified, after providing for a time-value of money provision inclusive of risk adjustments for various factors, as non-current given the potential delays in receipt. Of the total VAT receivables, US$13.8 million (30 June 2019: US$13.8 million and 31 December 2018: US$13.8 million) relates to historic VAT pre July 2017. The assessment of the carrying value of the VAT receivables under the historic VAT legislation required significant judgement over the timing of future payments, progress and finalisation of VAT audits, ongoing discussions with the relevant authorities in Tanzania and the wider operating environment.

A further US$24.2 million (30 June 2019: US$19.1 million and 31 December 2018: US$11.2 million) of VAT is receivable which relates to VAT under the current legislation, effective from July 2017. The assessment of the carrying value of the VAT receivable under the current VAT legislation required significant judgement over the timing of future payments, the definition of raw minerals under the new VAT legislation, ongoing discussions with the relevant authorities in Tanzania, legal advice, a formal rejection letter received from the Tanzania Revenue Authority and the Companyâ€™s legal objection thereto and the wider operating environment. Management have considered the current legislation and consider that input VAT can continue to be recovered in relation to the export of rough diamonds, however note that the current legislation is unclear. As such, Management consider the VAT receivables under the new VAT legislation to be valid. Accordingly, the Group is considering various alternatives in pursuing payment in accordance with legislation.

While the total VAT balance is considered receivable, significant uncertainty exists regarding the timing of receipt. Accordingly, the receivable has been discounted by US$24.5 million (30 June 2019: US$22.8 million and 31 December 2018: US$4.2 million), which required estimates as to the timing of future receipts and determination of a risk adjusted discount rate. The carrying value of the non-current receivable after adjusting for the time-value of money provision is US$13.5 million (30 June 2019: US$10.1 million and 31 December 2018: US$20.8 million). The Group recognised a net consolidated impairment charge of US$1.6 million comprising US$1.7 million, being managementâ€™s estimate of the impact of the delayed recoverability of the Tanzania VAT receivable, and a recoupment of US$0.1 million previously impaired in respect of the KEM JV receivable. A discount rate of 14% has been applied to the expected cash receipts inclusive of estimated country credit risk. A 1% increase in the discount rate would increase the provision by US$0.4 million and a one year delay would increase the provision by US$0.7 million.

BEE guarantee

The BEE partners obtained bank financing from ABSA, RMB and Investec (the â€œBEE Lendersâ€) to refinance amounts owing by the BEE partners to Petra, which had provided funding to the BEE partners to enable them to acquire their interests in Finsch and Cullinan. As part of the refinancing, the Group provided a guarantee to the BEE Lenders over the repayment of loans advanced to the Groupâ€™s BEE partners. The BEE partners will settle their loan obligations with the BEE Lenders from their share of future operational cash flows, either through repayment of the amounts owing to the BEE partners by Petra or through recoverable advances provided by Petra from Group treasury.

Judgement has been applied by management in assessing the risk of the BEE partners defaulting under their obligations to the BEE Lenders, including any acceleration of repayments due to future covenant positions. Management have considered the Groupâ€™s future cash flows forecasts, the likelihood of settlement lender facilities remaining available given the possible covenant breaches and its ability to meet planned forecast BEE partner distributions. Accordingly management are of the opinion that the risk of default by the BEE partners to the BEE Lenders is remote (refer to going concern note above and note 12 for further details).

Life of mine and ore reserves and resources

There are numerous risks inherent in estimating ore reserves and resources and the associated current life of mine plan. The life of mine plan is the current approved management plan for ore extraction that considers specific resources and associated capital expenditure. The life of mine plan frequently includes less tonnes than the total reserves and resources that are set out in the Groupâ€™s Reserves and Resources Statement and which management may consider to be economically viable and capable of future extraction.

Management must make a number of assumptions when making estimates of reserves and resources, including assumptions as to exchange rates, rough diamond and other commodity prices, extraction costs, recovery and production rates. Any such estimates and assumptions may change as new information becomes available. Changes in exchange rates, commodity prices, extraction costs, recovery and production rates may change the economic viability of ore reserves and resources and may ultimately result in the restatement of the ore reserves and resources and potential impairment to the carrying value of the mining assets and life of mine plans.

The current life of mine plans are used to determine the ore tonnes and capital expenditure in the impairment tests. Ore reserves and resources, both those included in the life of mine and certain additional tonnes which form part of reserves and resources considered to be sufficiently certain and economically viable, also impact the depreciation of mining assets depreciated on a unit of production basis. Ore reserves and resources further impact the estimated date of decommissioning and rehabilitation.

Leases

Management has made certain assumptions and applied judgement around certain service contracts with medium term renewal terms. In assessing the applicable term of the service contracts, the Group has concluded that it is unlikely that such contracts will be renewed and thus they are only included in the lease calculation up to the date of lease termination.

Other key estimates and judgements

In addition to the key estimates and judgements disclosed above, the following estimates and judgements have not significantly changed from those disclosed in the FY 2019 Annual Report and will be discussed in further detail in the FY 2020 Annual Report:

Provision for rehabilitation
Inventory and inventory stockpile
Depreciation
Pension and post-retirement medical fund schemes
Net investments in foreign operations

3. DIVIDENDS

No dividends have been declared in respect of the current Period under review (30 June 2019: US$nil and 31 December 2018: US$nil).

4. SEGMENTAL INFORMATION

Segment information is presented in respect of the Groupâ€™s operating and geographical segments:

Mining â€“ the extraction and sale of rough diamonds from mining operations in South Africa and Tanzania.

Exploration â€“ exploration activities in Botswana.

Corporate â€“ administrative activities in the United Kingdom.

Segments are based on the Groupâ€™s management and internal reporting structure. Management reviews the Groupâ€™s performance by reviewing the results of the mining activities in South Africa and Tanzania, reviewing the results of exploration activities in Botswana and reviewing the corporate administration expenses in the United Kingdom. Each segment derives, or aims to derive, its revenue from diamond mining and diamond sales, except for the corporate and administration cost centre.

Segment results, assets and liabilities include items directly attributable to a segment, as well as those that can be allocated on a reasonable basis. Segment results are calculated after charging direct mining costs, depreciation and other income and expenses. Unallocated items comprise mainly interest-earning assets and revenue, interest-bearing borrowings and expenses and corporate assets and expenses. Segment capital expenditure is the total cost incurred during the year to acquire segment assets that are expected to be used for more than one period. Eliminations comprise transactions between Group companies that are cancelled on consolidation. The results are not materially affected by seasonal variations. Revenues are generated from tenders held in South Africa and Antwerp for external customers from various countries, the ultimate customers of which are not known to the Group.

¹ The Group predominantly enters into hedge contracts where the risk being hedged is the volatility in the South African Rand and US Dollar exchange rates affecting the proceeds in South African Rand of the Groupâ€™s US Dollar denominated diamond tenders. In the event of a capital raising, as was the case with the Rights Issue in FY 2018, the Group may also enter into short dated hedges to facilitate the conversion between functional currencies across the Group as was the case with the settlement of the South African lender facilities out of the Pound Sterling Rights Issue proceeds in July 2018. The fair value of the Groupâ€™s hedges as at the end of the Period are based on Level 2 mark-to-market valuations performed by the counterparty financial institutions. The contracts are all short dated in nature and mature within the next 12 months. An unrealised gain of US$2.7 million (30 June 2019: US$4.0 million gain and 31 December 2018: US$13.7 million loss) in respect of foreign exchange contracts and inter-group loans held at Period end and a net realised foreign exchange loss of US$3.4 million (30 June 2019: US$1.0 million gain and 31 December 2018: US$2.8 million loss) in respect of foreign exchange contracts closed during the Period is included in the net finance and expense amount.

7. PROPERTY, PLANT AND EQUIPMENT

The net movement in property, plant and equipment for the Period is a decrease of US$17.5 million (30 June 2019: US$276.4 million and 31 December 2018: US$55.9 million). This is primarily as a result of:

an increase in property, plant and equipment from capital expenditure of US$26.5 million (30 June 2019: US$86.9 million and 31 December 2018: US$44.3 million), and
an increase in the rehabilitation asset of US$nil million (30 June 2019: US$nil and 31 December 2018: US$nil)

offset by:

the movement in the US$/ZAR foreign exchange rate resulting in a foreign exchange increase on Rand based assets of US$3.0 million (30 June 2019: US$28.4 million decrease and 31 December 2018: US$47.1 million decrease);
depreciation of US$47.0 million (30 June 2019: US$106.7 million and 31 December 2018: US$50.8 million);
the impairment of the Cullinan, Finsch, Koffiefontein and Williamson assets of US$nil (30 June 2019: US$223.7 million and 31 December 2018: US$nil);
the disposal of the Helam assets of US$nil (30 June 2019: US$1.5 million and 31 December 2018: US$1.5 million); and
assets of US$nil (30 June 2019: US$3.0 million and 31 December 2018: US$0.8 million) disposed of during the Period.

8. SHARES ISSUED

Allotments during the Period ending 31 December 2019 were in respect of:

the award of shares to Johan Dippenaar and James Davidson of 62,304 and 32,554 respectively under the 2012 Performance Share Plan, in receipt of performance measured over the period 1 July 2017 to 30 June 2019.

As at 31 December 2019, the Company had committed to future capital expenditure totalling US$5.9 million (30 June 2019: US$6.6 million and 31 December 2018: US$19.5 million), mainly comprising Cullinan US$2.5 million (30 June 2019: US$3.1 million 31 December 2018: US$8.1 million), Finsch US$2.3 million (30 June 2019: US$1.9 million 31 December 2018: US$9.4 million), Koffiefontein US$0.4 million (30 June 2019: US$0.5 million 31 December 2018: US$1.9 million) and Williamson US$0.7 million (30 June 2019: US$1.1 and 31 December 2018: US$0.1 million).

11. RELATED PARTY TRANSACTIONS

The Groupâ€™s related party BEE partners, Kago Diamonds (Pty) Ltd (â€œKago Diamondsâ€) and Sedibeng Mining (Pty) Ltd (â€œSedibeng Miningâ€), and their gross interests in the mining operations of the Group are disclosed in the table below.


Mine	Partner and respective interest as at 31 December 2019 (%)	Partner and respective interest as at 31 December 2018 (%)	Partner and respective interest as at 30 June 2019 (%)
Cullinan	Kago Diamonds (14%)	Kago Diamonds (14%)	Kago Diamonds (14%)
Finsch	Kago Diamonds (14%)	Kago Diamonds (14%)	Kago Diamonds (14%)
Koffiefontein	Kago Diamonds (14%)	Kago Diamonds (14%)	Kago Diamonds (14%)

A prior restructuring of the Group and its BEE Partner structures allowing for a simplified Group structure resulted in the IPDET acquiring a 12% interest in each of the Groupâ€™s South African operations, with Petraâ€™s commercial BEE Partners holding the remaining 14% interest through their respective shareholdings in Kago Diamonds, in which Petra has a 31.46% interest. The effective interest percentages attributable to the remaining operations for the Groupâ€™s shareholders, as a result of the restructuring, are disclosed in the table below:

Mine		Resultant Groupâ€™s effective interest %
Cullinan		78.4

Â¹ Included in non-current receivables are amounts advanced during the Period of US$6.3 million (30 June 2019: US$26.8 million and 31 December 2018: US$12.5 million).

² Included in current trade and other receivables are amounts previously advanced to KEM JV in respect of a working capital facility and equipment finance facility of US$8.5 million (30 June 2019: US$8.6 million and 31 December 2018: US$9.7 million) and the balance of the KEM JV purchase consideration of US$3.1 million (30 June 2019: US$3.1 million and 31 December 2018: US$3.1 million). During FY 2019 the Group received payments of US$3.1 million in respect of the working capital facility and equipment finance facility. In FY 2019, the Group has applied the expected credit loss impairment model to the KEM JV receivables, taking into account various factors, and the expected credit loss was deemed to be US$7.3 million.

Kago Diamonds is one of the BEE partners which obtained bank financing from ABSA, RMB and Investec (the â€œBEE Lendersâ€) to acquire its interests in Cullinan and Finsch. The Group has provided a guarantee to the BEE Lenders for repayment of loans advanced to the Groupâ€™s BEE Partners (refer to note 12 for further detail).

Rental income receivable

The Group received US$nil (30 June 2019: US$nil and 31 December 2018: US$nil) of rental income from Pella Resources Ltd and US$0.1 million (30 June 2019: US$0.1 million and 31 December 2018: US$nil) from Alufer Mining Ltd. The Group has US$0.3 million (30 June 2019: US$0.3 million and 31 December 2018: US$0.3 million) receivable from Pella Resources Ltd and US$nil (30 June 2019: US$0.1 million and 31 December 2018: US$0.1 million) receivable from Alufer Mining Ltd, both companies of which Mr Pouroulis is a director.

BEE Loans Receivable

The non-current BEE loans receivable represents those amounts receivable from the Groupâ€™s BEE partners (Kago Diamonds, Sedibeng Mining and the IPDET) in respect of financing their interest in the Koffiefontein mine, advances provided to the BEE partners to enable the BEE partners to discharge interest and capital commitments under the BEE Lender facilities (refer below guarantee provided by the Company) and other advances to the BEE partners which have enabled them to make distributions to their beneficiaries (Petra directors do not qualify as beneficiaries under the IPDET Trust Deed).

As a result of prior period delays in the Cullinan plant ramp-up and the Finsch SLC ramp-up, the Group has elected to advance the BEE partners funds using Group treasury to enable the BEE partners to service their interest and capital commitments under the BEE Lender facilities (refer below). As a result, the BEE loans receivable due to Petra have increased. The BEE partners are also required to settle future interest and capital repayments under the BEE Lender facilities and Petra may, at its discretion, elect to advance the BEE partners funds to enable the BEE partners to service those future interest and capital commitments. These loan advances will be recoverable from the BEEâ€™s share of future cash flows from the underlying mining operations.

Group guarantee provided to BEE Lenders

The BEE partners obtained bank financing from ABSA, RMB and Investec (the â€œBEE Lendersâ€) to refinance amounts owing by the BEE partners to Petra, which had provided funding to the BEE partners to enable them to acquire their interests in Cullinan and Finsch. As part of the refinancing, the Group provided a guarantee to the BEE Lenders over the repayment of loans advanced to the Groupâ€™s BEE partners. The BEE partners will settle their loan obligations with the BEE Lenders from their share of future operational cash flows, either through repayment of the amounts owing to the BEE partners by Petra or through recoverable advances provided by Petra from Group treasury.

As at 31 December 2019, the BEE lender facility for which Petra stands surety was US$49.3 million (30 June 2019: US$72.5 million and 31 December 2018: US$72.5 million) with interest and capital commitments as detailed below:

US$ million	Interest repayments	Capital repayments	Balance

BEE Lender facility as at 31 December 2019			49.3
Due and payable within 12 months	(8.2)	(24.4)	(32.6)
Due and payable in 1 â€“ 2 years			16.7

The BEE Lender facility forms part of Petraâ€™s Consolidated Net Debt for Petraâ€™s covenant measurement purposes and is subject to the same covenant requirements (refer to note 9 for further detail).

During the Period, the BEE Lender facility was amended with an amendment to the interest rate and margin (same interest rate ratchet terms as disclosed in note 9) and an extension to the repayment profile. The BEE Lender facility bears interest at SA JIBAR plus 8.0%, is repayable in bi-annual instalments (capital plus interest) in November and May, with a final repayment date in May 2021. The probability of repayment default by the BEE Partners to Absa, Investec and RMB and any subsequent call by the Lender Group on the guarantee provided by Petra is considered remote.

15. IMPAIRMENT CHARGE

The carrying amounts of the Groupâ€™s assets are reviewed at each reporting date to determine whether there is any indication of impairment or reversal of historic impairment. If there is any indication that an asset may be impaired, its recoverable amount is estimated. The recoverable amount is determined on a fair value less cost to develop basis.

During the Period under review, the Group reviewed the carrying value of its investments, loan receivables and operational assets for indicators of impairment. Following the assessment, no impairment of property, plant and equipment was considered appropriate for Cullinan, Finsch, Koffiefontein and Williamson. The Group recognised a net consolidated income statement charge of US$1.6 million comprising of US$1.7 million, being managementâ€™s estimate of the recoverability of the Tanzania VAT receivable, and recoupment of US$0.1 million previously impaired in respect of the KEM JV receivable.

Details of the impairment assessment are shown below:

30 June 2019

During FY 2019, the Group reviewed the carrying value of its investments, loan receivables and operational assets for indicators of impairment. Following the assessment, impairment of property, plant and equipment were considered appropriate for Cullinan, Finsch, Koffiefontein and Williamson. The Group recognised a consolidated income statement charge of US$246.6 million comprising of US$223.7 million, being managementâ€™s estimate of recoverable value of the Cullinan, Finsch, Koffiefontein and Williamson assets, and US$22.9 million, being managementâ€™s estimate of the recoverability of other receivables due from external parties. For impairment considerations of Helam and KEM JV in respect of FY 2019, refer to note 16.

Cullinan, Finsch, Koffiefontein and Williamson impairment considerations and assumptions

The Group performs impairment testing on an annual basis of all operations and when there are potential indicators of impairment. The impairment testing performed resulted in impairments of the Cullinan, Finsch, Koffiefontein and Williamson assets. The key assumptions used in determining the recoverable value calculations, determined on fair value less cost to develop basis, are listed in the table below:

Group assumptions:

Key assumptions	Explanation
LOM and recoverable value of reserves and resources	Economically recoverable reserves and resources are based on managementâ€™s expectations based on the availability of reserves and resources at mine sites and technical studies undertaken in house and by third party specialists. The LOM for the operations are as follows: Cullinan: FY 2029 (FY 2019: FY 2029) Finsch: FY 2030 (FY 2019: FY 2030) Koffiefontein: FY 2024 (FY 2019: FY 2024) Williamson: FY 2032 (FY 2019: FY 2032) Resources remaining after the current LOM plans have not been included in impairment testing for the operations.
LOM reserves and resources	Cullinan â€“ Life of mine over the next 10 years (FY 2019: 10 years); total resource processed 40.4 Mt (FY 2019: 40.5 Mt).
	Finsch â€“ Life of mine over the next 11 years (FY 2019: 11 years); total resource processed 35.7 Mt (FY 2019: 35.8 Mt).
	Koffiefontein â€“ 5 years (FY 2019: 5 years) life of mine plan; total resource processed 5.4 Mt (FY 2019: 4.8 Mt) ROM.
	Williamson â€“ 12 years (FY 2019: 13 years) life of mine plan: total resource processed 56.1 Mt (FY 2019: 64.1 Mt).
LOM â€“ capital expenditure	Management has estimated the timing and quantum of the capital expenditure based on the Groupâ€™s current LOM plans for each operation. There is no inclusion of capital expenditure to enhance the asset beyond exploitation of the LOM plan orebody.
Diamond prices	The diamond prices used in the impairment test have been set with reference to recent achieved pricing and market trends, and long-term diamond price escalators are informed by industry views of long-term market supply / demand fundamentals. The 31 December 2019 impairment testing models account for a lower starting diamond price (FY 2020) when compared to the 30 June 2019 impairment models, reflecting the current weakness in diamond prices. Diamond price recovery driven by expected product mix and market stabilisation is forecast for H2 FY 2020 and the impairment models incorporate diamond price escalation of 2.5% above a long-term US inflation rate of 2.5% for FY 2021 and 2.8% above a long-term US inflation rate of 2.5% per annum from FY 2022 to FY 2030. This equates to a 2.7% real CAGR for the ten year period from FY 2021 to FY 2030. Estimates for the contribution of exceptional diamonds sold for more than US$5 million each are determined with reference to historical trends. 30 June 2019 impairment testing models incorporated diamond price escalation of 2.8% above a long-term US inflation rate of 2.5% per annum from FY 2022 to FY 2030. This equates to a 2.5% real CAGR for the ten year period from FY 2021 to FY 2030. Estimates for the contribution of exceptional diamonds sold for more than US$5 million each are determined with reference to historical trends.
Discount rate	A discount rate of 8.5% (30 June 2019: 8.5%) was used for the South African operations and 9.0% (30 June 2019: 9.0%) for Williamson. Discount rates calculated based on a nominal weighted cost of capital including the effect of factors such as market risk and country risk as at the Period end.
Cost inflation rate	Long-term inflation rates of 3.5%â€“7.5% (30 June 2019: 3.5%â€“7.5%) above the long-term US$ inflation rate were used for Opex and Capex escalators. Opex savings of 5% per annum have been applied from FY 2020 onwards in line with the Project 2022 strategy implemented by the Group.
Exchange rates	Exchange rates are estimated based on an assessment of current market fundamentals and long-term expectations. The US$/ZAR exchange rate range used for all South African operations commenced at ZAR14.50 (30 June 2019: ZAR14.00), further devaluing at 3.9% (30 June 2018: 3.9%) per annum over a period of three years, reverting to 3.4% per annum thereafter.
Valuation basis	Discounted present value of future cash flows.
Williamson	At Williamson, the key judgement is around the recoverability of the VAT receivable under the new legislation effective 20 July 2018. As detailed in note 2, Management consider the future VAT to be fully recoverable. However, if the VAT were not to be recoverable the impact would be to increase the impairment by an additional US$61.9 million.

Sensitivity analysis

The impact of applying sensitivities on the key inputs based on managementâ€™s assumptions at 31 December 2019 is noted below:

	Additional impairment charge
(US$ million)	Cullinan	Finsch	Koffiefontein	Williamson
Base case
Increase in discount rate by 2%	-47.5	-32.4	-0.7	-11.0
Reduction in pricing by 5% over Life of Mine	-55.9	-47.1	-8.5	-25.0
Reduction in short-term production by 10%	-36.3	-13.1	-10.0	-14.5
Increase in Opex by 5%	-25.0	-22.9	-6.9	-19.0
Strengthening of the ZAR from US$/ZAR14.50 to US$/ZAR13.50	-41.3	-49.3	-10.8	n/a

16. DISPOSAL OF OPERATIONS

There were no disposals during the Period under review.

30 June 2019

Disposal of KEM JV

On 5 December 2018, the Group and its BEE partners disposed of their 75.9% interest in the KEM JV operation to the Companyâ€™s joint venture partner Ekapa Mining (Pty) Ltd (â€œEkapa Miningâ€) for a gross cash consideration of ZAR300 million (US$18.6 million) (the â€œDisposalâ€) comprising deferred and contingent elements.

The Disposal was on a going concern basis, with Ekapa Mining taking on all of the Companyâ€™s financial, employee, environmental, health, safety and social obligations with regards to the KEM JV operation.

According to the terms, the purchase consideration is to be settled as follows:

ZAR60 million payable in 24 monthly instalments starting on 1 April 2019;
the balance, ZAR 240 million, of the purchase consideration is repayable from a 50% share of future operating cash flows above set benchmark thresholds, including proceeds from the sale of assets adjusted for sustaining capital of between ZAR110 million and ZAR130 million per annum, for a period of five years to 30 June 2024; and possible proceeds from a pending insurance claim, that is subject to ongoing discussions, in relation to the mud-rush incident at Bultfontein, as previously announced. The Company has fair valued the balance of the purchase consideration and deemed it to be US$nil, having considered the historical trading performance of the asset, knowledge of the mine and risks and uncertainties.

The financial results of KEM JV have been disclosed in the Consolidated Income Statement in Loss on discontinued operation. The KEM JV mining operation was a separate operating segment for the purposes of the Groupâ€™s segmental reporting.

During FY 2019, the Company advanced US$9.4 million funding to the KEM JV; of this amount, US$3.9 million was recovered. Management assessed the recoverability of the remaining US$5.5 million and as a result of the assessment an impairment charge of US$4.2 million was recognised in the Consolidated Income Statement. In assessing the recoverability, management considered the historical trading performance of the KEM JV, the current downturn in the diamond market, current economic climate, payment history and recent press coverage involving the KEM JV operation. The remaining balance was included under current trade and other receivables.

As a result of the above assessment by management of the loan receivable, management also impaired the remaining balance of the purchase consideration, reducing it to US$nil, and an impairment charge of US$3.1 million was recognised in the Consolidated Income Statement.

INDEPENDENT REVIEW REPORT TO PETRA DIAMONDS LIMITED

Introduction

We have been engaged by the Company to review the condensed set of financial statements in the half-yearly financial report for the six months ended 31 December 2019 which comprises the consolidated income statement, consolidated statement of comprehensive income, consolidated statement of changes in equity, consolidated statement of financial position, the consolidated statement of cashflows and the related notes.

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 condensed set of financial statements.

Directorsâ€™ responsibilities

The half-yearly financial report 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 of the United Kingdomâ€™s Financial Conduct Authority.

As disclosed in note 2, the annual financial statements of the group are prepared in accordance with International Financial Reporting Standards (IFRSs) as adopted by the European Union. The condensed set of financial statements included in this half-yearly financial report has been prepared in accordance with International Accounting Standard 34, â€˜â€˜Interim Financial Reportingâ€™â€™, 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 half-yearly 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, â€˜â€˜Review of Interim Financial Information Performed by the Independent Auditor of the Entityâ€™â€™, issued by the Financial Reporting Council 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.

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 half-yearly financial report for the six months ended 31 December 2019 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 Kingdomâ€™s Financial Conduct Authority.

Use of our report

Our report has been prepared in accordance with the terms of our engagement to assist the Company in meeting its responsibilities in respect of half-yearly financial reporting in accordance with the Disclosure Guidance and Transparency Rules of the United Kingdomâ€™s Financial Conduct Authority and for no other purpose. No person is entitled to rely on this report unless such a person is a person entitled to rely upon this report by virtue of and for the purpose of our terms of engagement or has been expressly authorised to do so by our prior written consent. Save as above, we do not accept responsibility for this report to any other person or for any other purpose and we hereby expressly disclaim any and all such liability.
