A journey of perfection

The Maluti Mountains, in the Kingdom of Lesotho, is home to 

the world’s highest situated diamond mine – Letšeng. At 3 100m 

above sea level, it is not only the altitude that makes the mine unique. 

Letšeng is renowned for some of the most distinctive diamonds ever 

recovered. In the past 10 years since Gem Diamonds took the mine over, four 

of the 20 largest white diamonds ever recorded were recovered at Letšeng. It is 

here in these rugged mountains that the remarkable 314 carat diamond, named 
the Letšeng Destiny, was unearthed in May 2015.

In line with Gem Diamonds’ strategic goal to maximise the revenue received from these 

diamonds, a partnership arrangement was entered into, whereby the Group participates in 

further margin from the final polished sale of the diamond.

The result of the polished diamond was an exceptional 105.07 carat D flawless pear-
shaped diamond – unveiled in August 2016 and named the Graff Vendôme.

An additional 12 diamonds were created from the Letšeng Destiny with the 
largest being 17.10 carats.

No one can predict when a large, exceptional find such as the Destiny will be made – although, given the 
rich history of our Letšeng mine, pinpointing the where may not be as challenging.

Famous Letšeng diamonds
A strong track record

The Letšeng mine in Lesotho is renowned for its recovery of some of the world’s most valuable 
diamonds, achieving the highest US$ per carat of any kimberlite diamond mine in the world. 
Letšeng regularly produces diamonds of exceptional size and colour. In line with the Group’s 
strategic goal to maximise the revenue achieved from remarkable diamonds, certain diamonds 
are sold into partnership arrangements whereby the Group participates in further margin from 
the final polished sale. The 314 carat Letšeng Destiny recovered and sold into partnership in the 
previous year, yielded exceptional polished diamonds further contributing to revenue in 2016.

299 carat yellow diamond
Recovered: 2014
Sold for: undisclosed*

This diamond was recovered in 

December 2014 and sold into a 
partnership arrangement in 
January 2015. Unmasking 

its true radiance, the gem 
was cut and polished by 
expert artisans with 
coloured diamond 
expertise, which resulted in 
a magnificent 132 carat 
fancy intense yellow 
cushion-shaped polished 
diamond, along with eight 
other yellow diamonds, the 

largest being a 21 carat fancy yellow 
pear shape. The 132 carat gem, aptly 

named The Golden Empress, was set 

into a breathtaking Graff 

signature necklace, 
adorned with 30 other 
cushion-cut yellow 
diamonds. 

The 357 carat ‘Letšeng Dynasty’ 
Recovered: 2015
Sold for: US$19.3 million 

The Letšeng Dynasty was recovered in July 2015 and 

sold for US$19.3 million in September 2015, achieving 
the highest value ever for a single Letšeng diamond. 
The name given was to symbolise the 

succession of diamonds from the 

same family. 

During 2016, Graff unveiled the Venus, a 118 carat 
heart-shaped, D flawless diamond, which was polished 
from the Letšeng Dynasty, making it the largest of its 
kind in the world. In total, 23 polished diamonds 
were extracted from this one rough 
diamond.

The 314 carat 
‘Letšeng Destiny’
Recovered: 2015
Sold for: undisclosed*

The Letšeng Destiny was recovered in May 
2015 and sold into a partnership arrangement in June 2015. The 
name was given to signify a hidden power believed to control future 
events. During 2016, the Letšeng Destiny has yielded a main 
polished 105 carat pear-shaped D colour flawless diamond, the 
Graff Vendôme, making it the largest cut and polished diamond of 
its kind in Graff’s history. Twelve smaller diamonds of D colour were 
also extracted from the rough diamond, totalling a polished weight 
of 164 carats. 

The 493 carat ‘Letšeng Legacy’
Recovered: 2007
Sold for: US$10.4 million

The Letšeng Legacy is also ranked in the top 20 largest rough white diamonds 
recorded and its name highlighted the growing legacy that the Letšeng 

mine in Lesotho was creating as a producer of significant large white 

diamonds. This diamond was recovered in September 2007 
and was sold for US$10.4 million in November 2007. 
Twenty polished diamonds were extracted 
from this rough diamond.

*  Sold into partnership arrangement

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements5

In 2016, Letšeng experienced a paucity of exceptional iconic diamonds but continued to 
recover large, high-quality diamonds. The largest diamond recovered in 2016 was a 160 carat 
diamond. The highest US$ per carat achieved for a single diamond during the year was for an 
11.8 carat pink diamond, which achieved US$187 700 per carat, making it the third highest of its 
kind in the Group’s history. 

The 550 carat ‘Letšeng Star’ 
Recovered: 2011
Sold for: undisclosed*

The 550 carat Letšeng Star was recovered in August 2011 and was so named to signify the growing number of  ‘stars’ in Letšeng’s 
constellation of large diamonds recovered. The Letšeng Star is also ranked in the top 20 largest white rough diamonds on record and the 
second largest white diamond to be recovered at Letšeng. This diamond yielded 12 pairs of pear shaped diamonds, as well as a 
main polished stone of 33 carats, also a pear shape, to form a unique collection of over 165 carats of D flawless and 
internally flawless polished gems stemming from this single rough diamond.

The 478 carat ‘Leseli La Letšeng’
Recovered: 2008
Sold for: US$18.4 million

The ‘Leseli La Letšeng’, which translates to ‘Light of Letšeng’, reflecting the 
diamond’s remarkable colour and clarity, was recovered in September 2008 and 
is also ranked in the top 20 largest rough white diamonds recorded. This 
diamond was the third significant recovery from the Letšeng mine in as many 
years and was sold in November 2008 for US$18.4 million (during the height of 
the global financial crisis). 

The fame of this diamond extends further in that it 
revealed a 102 carat round shaped, D colour 
internally flawless diamond, making it the 
largest round-shaped polished diamond ever 
to be graded D colour internally flawless by 
the Geomological Institute of America (GIA). 
A further 10 exquisite polished diamonds 
were also revealed.

The 603 carat ‘Lesotho Promise’
Recovered: 2006
Sold for: US$12.4 million

The 603 carat Lesotho Promise was recovered in August 
2006 and together with being ranked in the top 20 of 
the world’s largest white diamonds on record, is also the 
largest diamond to emerge from the Letšeng mine to 
date. The Lesotho Promise was sold for US$12.4 million 
in October 2006 and was 
subsequently polished into 
26 D flawless and internally 
flawless diamonds, the largest of 
which was a 76 carat pear shaped 
diamond. 

All 26 polished diamonds were 
fashioned into a single necklace 
by Graff.

12 carat Blue diamond
Recovered: 2013
Sold for: US$7.5 million
This rare 12.47 carat blue diamond was recovered at Letšeng in September 
2013. It was sold a month later on tender in Antwerp for a record price of 
US$603 047 per carat (US$7.5 million), the highest US$ per carat for any Letšeng 
rough diamond sold to date.

Chairman’s statement

Roger Davis Chairman

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements9

Dear shareholder,

137 000 carats recovered and sold to date. 20.5 million carats are 
contained within the resource.

On behalf of the Board, it is my pleasure to present Gem 
Diamonds’ 2016 Annual Report. I believe this report offers a fair 
and balanced account of the business, its performance over the 
last year and its prospects going forward. As an organisation, 
Gem Diamonds remains committed to transparent and relevant 
reporting to you, its shareholders.

2016 IN REVIEW 
Gem Diamonds’ strategy is built on three pillars; namely value 
creation, growth and sustainability. This broad-based approach 
was developed to allow the Group the flexibility to respond to an 
ever-changing operating context and has enabled it to adapt to 
short-term opportunities and challenges while moving towards 
its long-term goal of delivering sustainable shareholder returns.

The 2016 financial year was challenging for the Group’s two 
operations. Operationally, the Letšeng mine performed well, with 
all production metrics achieved. In addition, the demand for, and 
prices of, its large, high-quality, white diamonds remained 
relatively firm throughout the year. However, the decline in the 
number of diamonds larger than 100 carats recovered during 
the year, adversely impacted the Group’s revenue, projects and 
cash flow. 

Despite the paucity in the number of large diamonds recovered 
during 2016, Letšeng continued to recover exceptional, high-
quality diamonds demonstrated through the recovery of two rare 
and valuable pink diamonds of 11.78 and 12.31 carats, which were 
sold for US$2.2 million and US$1.4 million, respectively. A large 
160 carat diamond was also recovered in 2016 and sold into a 
partnership agreement at a top price, reinforcing the quality of 
the Letšeng asset. 

Development of the Ghaghoo mine continued following the 
decision to downsize the operation and reduce its associated cost 
structure. Regrettably, the market for smaller commercial goods 
(such as those mined at Ghaghoo) remained under pressure and 
prices for these goods have declined from US$210 to US$142 per 
carat. Largely due to the depressed market and low realised 
prices, the Board made the difficult decision to place the 
operation on care and maintenance in February 2017 resulting in 
an impairment of US$170.8 million. Ghaghoo remains a key asset 
for the Group and its expansion opportunities, when diamond 
prices recover, will strengthen the Group’s position. The orebody 
and all of its characteristics are well understood with just under 

* Refer to Note 3, Operating profit, for the definition of non-GAAP measures.

Against this backdrop, the Group delivered a satisfactory 
performance. The Group generated underlying EBITDA* of 
US$63 million with an attributable profit of US$18 million before a 
non-cash impairment charge of US$176 million. The Group ended 
the year with a cash balance of US$31 million and undrawn 
facilities of US$53 million as at 31 December 2016.

SUPPORTING INDUSTRY ADVOCACY
The Group understands the importance of protecting and 
enhancing the premium brand of diamonds. Gem Diamonds was 
one of the founding members of the Diamond Producers 
Association (DPA). The Group’s association with the DPA has 
allowed Gem Diamonds to play an active role in maintaining and 
enhancing consumer demand for and confidence in diamonds. 

PARTNERING FOR GROWTH
Gem Diamonds is committed to partnering with its stakeholders 
to create mutual benefit and shared growth. The Group strives to 
create positive impact through social initiatives that will outlast 
the life of its mines. Therefore, the Group’s focus is on 
implementing sustainable projects that address the needs of 
project-affected communities (PACs). This is done through 
constant engagement with stakeholders at all levels of the 
business and using their feedback to guide corporate social 
investment strategies. 

On 6 May 2016, the Letšeng Diamond Discovery Centre was 
officially opened by His Majesty, King Letsie III in Maseru. The 
centre tells the story of Lesotho’s diamond industry in an 
interactive manner, focusing on the history of diamond mining at 
Letšeng. The centre was built to promote knowledge and serve as 
a foundation for Basotho learners who wish to learn more about 
the diamond mining industry and possibly pursue careers in the 
field. To date almost 1 600 visitors have passed through the 
centre, the vast majority of whom are school children.

STRIVING FOR ZERO HARM
Gem Diamonds endeavours to incorporate sustainability best 
practice into every level of the business, keeping up-to-date with 
new developments. Pursuing its goal of zero harm in all areas is a 
continued priority. During 2016, the Group experienced a 
fatality-free year and continues to invest in safety training and 
capability building in its effort to embed a strong safety culture 
throughout the organisation. Pleasingly, the all injury frequency 
rate achieved during the year is the lowest in the history of 
the Group.

Chairman’s statement continued

PURSUING EXCELLENCE IN CORPORATE 
GOVERNANCE
The Board is committed to the highest standards of corporate 
oversight and believes that strong governance is critical to the 
Group’s sustainability. 

The Board is tasked with providing leadership and guidance to 
the Group within a framework of controls. It also ensures that the 
necessary financial and human resources are in place for the 
Group to meet its objectives and increase shareholder value.

In 2016, the Board once again conducted a detailed Board 
evaluation. The assessment reviewed the effectiveness of the 
Board as a collective and the contribution of the individual 
Directors. Furthermore, the Board evaluation exercise also looked 
at the composition of the Board and its committees’ conduct and 
decision-making; its approach to and implementation of risk 
management, management information and reporting; training, 
development and succession planning; and communication. The 
outcome of the assessment was used to inform the Board’s 
planning for the year and reinforced our commitment to applying 
best practices, and setting, monitoring and evaluating the high 
standards of governance we wish to maintain.

During the year, Alan Ashworth retired as Chief Operating Officer. 
On behalf of the Board, I would like to thank Alan for his tireless 
commitment to Gem Diamonds during his eight-year tenure. We 
welcomed Johnny Velloza as the new Chief Operating Officer in 
2016. Johnny brings a wealth of experience to the Group and his 
contribution has already been felt.

DIVIDEND 
In line with the Group’s strategy of returning cash to its 
shareholders, the Company paid a dividend of 5 US cents per 
share (US$6.9 million) and a special dividend of 3.5 US cents per 
share (US$4.9 million) in June 2016 in respect of the 2015 
financial year. 

Following a careful review of the 2016 results, the Board has 
decided to focus on cash preservation and is prudently 
recommending, despite the Group’s dividend policy, that no 
dividend is paid in respect of the 2016 financial year. The Group 
will continue to focus on capital management discipline and cost 
control at the operations to return to a position to recommend 
dividend payments to shareholders in the future.

OUTLOOK
The medium to long-term outlook for diamond demand is 
expected to remain favourable.

The strategic focus of the Group will remain on creating value by 
focusing on mining and selling diamonds efficiently and 
responsibly. Through disciplined execution of its core strategy, the 
Group is well positioned to maximise shareholder returns and 
remains confident in its ability to continue delivering returns to 
shareholders.

APPRECIATION AND FAREWELL
I will be stepping down at this year’s Annual General Meeting 
(AGM), following 10 years as Chairman of Gem Diamonds. It has 
been an honour to serve this dynamic business for almost a 
decade. I wish my successor well and know that they join a proud 
organisation with strong leadership and values. I would like to 
acknowledge the hard work and commitment of the entire Gem 
Diamonds team. To my fellow Board members – thank you for 
your insight and leadership throughout the year. To the host 
governments, thank you for your continued support. Finally, thank 
you to the Group’s shareholders. Gem Diamonds remains 
committed to delivering value to you in the year ahead.

Definition
Revenue represents the value of goods 
sold during the year (both rough and 
polished) and measures the level of 
operating activity and growth of the 
business. Revenue for the year is as 
reported in the consolidated income 
statement and excludes revenue 
achieved by Ghaghoo on the basis 
that the mine had not reached full 
commercial production for accounting 
purposes by the end of the year.

Definition
Underlying EBITDA means earnings before 
interest, tax, depreciation and amortisation. 
It excludes share-based payments, other 
income, foreign exchange differences and 
exceptional items.
Underlying EBITDA margin is calculated 
as underlying EBITDA as a percentage of 
revenue. Both these indicators provide a 
measure of the operating profitability of 
the business. Refer to Note 3, Operating 
profit, in the financial statements for the 
calculation of underlying EBITDA.

Definition
ROACE is a pre-tax measure of the 
efficiency with which the Group 
generates operating profits from its 
capital. ROACE is calculated as underlying 
EBITDA (as per Note 3, Operating 
profit, in the financial statements) less 
depreciation and amortisation divided 
by average capital employed (being total 
equity and non-current liabilities per 
the consolidated statement of financial 
position).

Commentary
The Group remains committed to 
maximising the value achieved on rough 
and polished diamond sales. Group 
revenue decreased by 24% compared 
to 2015 largely due to the paucity of 
exceptional large diamonds recovered at 
Letšeng which significantly impacted the 
overall US$ per carat realised and overall 
revenue. 
Ghaghoo concluded three sales during 
the year, generating US$7.2 million 
(2015: US$14.4 million) which is not 
included in Group revenue. 
Total sales for the year including 
Ghaghoo was US$197.2 million.

Commentary 
Underlying EBITDA of US$62.8 million 
is 39% lower than 2015 reflecting 
the impact of lower Group revenue, 
partly mitigated by the positive impact 
on the translation of the local costs 
into US dollars driven by the overall 
weakening of the local currencies 
against the US dollar. This resulted in an 
underlying EBITDA margin of 33%.

Underlying EBITDA does not include any 
results from Ghaghoo due to the mine 
not having reached full commercial 
production.

Commentary 
Pre-tax ROACE achieved 15%, mainly 
driven by lower Group revenue. Prior 
years’ ROACE is as reported at that point 
in time and includes all operations in 
existence in those relevant years. ROACE 
is calculated after taking into account the 
impairment of assets of US$172.9 million, 
mainly relating to Ghaghoo being placed 
on care and maintenance.

Definition
Basic EPS represents profit attributable 
to equity shareholders and is stated 
before exceptional items and after non-
controlling interest. This is a measure 
of profitability of the Group taking into 
account changes in the equity structure. 
EPS is calculated as reported in the 
consolidated income statement and in 
accordance with Note 8, Earnings per 
share, in the financial statements.

Commentary 
Basic EPS of 12.80 US cents per share is 
indicative of the lower earnings achieved. 
Basic EPS including exceptional items 
was a loss per share of 114.90 US cents, 
driven by the non-cash Ghaghoo asset 
impairment charge. There was no 
significant change in the capital structure 
of the Group.

Definition
Free cash generated represents net cash 
flows before financing activities and 
investing activities in expansion projects. 
This measures the cash-generating 
capability of the Group to fund future 
growth. Free cash generated is reflected 
in the statement of cash flows and 
is determined by cash flows from 
operating activities of US$70.7 million 
less sustaining capital of US$10.8 million, 
cash invested in Ghaghoo development 
and commissioning costs of 
US$18.0 million and waste cash costs 
incurred at Letšeng of US$70.4 million.

Commentary
While the Company remains committed 
to generating and returning cash to 
shareholders with capital and cash 
management discipline remaining a 
priority, the lower revenue achieved 
during the year at Letšeng and Ghaghoo 
negatively impacted the Group’s cash 
balance. The Group utilised existing 
cash resources and cash flows from 
operations to fund existing capital 
commitments and operating costs. 
The Group ended the year with 
US$3.8 million cash net of drawn down 
facilities of US$27.0 million after paying 
a dividend of US$11.8 million during the 
year in relation to the 2015 results.

Definition
Capital expenditure represents the 
amount invested in the Group’s organic 
growth plans. Capital expenditure is 
reflected in the statement of cash flows 
as purchases of property, plant and 
equipment and includes expansion and 
sustaining capital. 

Commentary
The Group invested US$10.8 million into 
sustaining capital expenditure which 
mainly comprised of US$7.6 million at 
Letšeng and US$2.6 million at Ghaghoo. 
At Letšeng, capital allocation was 
focused on stay in business capital with 
early stage investment in projects that 
will deliver future benefits.

Definition
The waste tonnes mined profile sets out 
the waste tonnes mined by Letšeng.

Commentary
The current year production represents 
6.7 million tonnes treated at Letšeng and 
0.2 million tonnes treated at Ghaghoo. 
Ore tonnes treated at Letšeng were 
similar to those treated in 2015. 
The additional expected tonnes of 
250 000 were not realised due to power 
outages caused by a severe snow 
storm experienced in July and August 
which resulted in all treatment plants 
running at reduced capacity for a period 
of 17 days. 
Ghaghoo operated at a reduced 
production rate during the year, following 
the decision to downsize the operation.

Commentary
Letšeng and Ghaghoo recovered 
108 206 (2015: 108 579) and 
40 976 (2015: 91 499) carats, respectively.
Letšeng’s production was similar to 
2015, with 108 206 carats recovered 
at a grade of 1.63 carats per hundred 
tonnes (cpht), in line with the expected 
reserve grade, at a reserve mine call 
factor of 101%. Production was hindered 
due to the extreme weather conditions 
experienced. 
Carats recovered at Ghaghoo were 55% 
lower than 2015 due to lower volumes 
of ore tonnes treated. As mining moved 
towards the centre of the ore body 
additional basalt diluted kimberlite 
was mined and this resulted in a lower 
recovered grade than anticipated. 

Commentary
The planned increase in mining 
production progressed during the year, 
with a 24% increase in waste mining in 
support of increasing the contribution of 
the higher-value Satellite pipe ore. Waste 
mined was also negatively impacted by 
the inclement weather conditions, as 
access to the pits was unattainable.

Definition
The LTIFR provides a measure of the 
safety performance of the Group, 
including partners and contractors. 
The LTIFR is measured on the reported 
LTI statistics for all of Gem Diamonds’ 
companies and sub-contractors, 
expressed as a frequency rate per 
200 000 man hours. Prior year rates 
include all operations in existence at that 
period.

Definition
The AIFR is another measure of the 
safety performance of the Group. The 
AIFR is calculated based on all reported 
injuries including minor injuries, medical 
treatment cases, restricted work injuries 
and LTIs of all Gem Diamonds’ companies 
and sub-contractors, and is expressed as 
a frequency rate per 200 000 man hours. 
Prior year rates include all operations in 
existence at that period.

Commentary
The Group recorded five LTIs during 
2016, two at Letšeng and three at 
Ghaghoo. As a result, the LTIFR for the 
year was 0.18, above the internal target 
of zero harm.

Commentary
The AIFR decreased to 1.93 in 2016 and 
is the lowest rate achieved in the history 
of the Group. This reflects the decrease in 
total injuries across the Group as a result 
of proactive safety management.

Principal risks and uncertainties
How we approach risk

The Group is exposed to a number of risks and uncertainties that could have a material impact 
on its performance and long-term growth. The effective identification, management and 
mitigation of these risks and uncertainties is a core focus of the Group as they are key to 
achieving the Company’s strategic objectives.

Central to Gem Diamonds’ approach to risk management is 
having the right Board and Senior Management team in place, 
with such members combining extensive experience in diamond 
mining, corporate governance, assurance management and 
knowledge of the local operating conditions in Lesotho and 
Botswana.

The Board is accountable for risk management, assisted primarily 
by the Audit and HSSE Committees, who together identify and 
assess change in risk exposure, along with the potential financial 
and non-financial impacts and likelihood of occurrence.

The Company is continually strengthening its risk management 
processes to provide informed assurance to the Board to assess 
current objectives. The Group internal audit function carries out 
the risk-based audit plan approved by the Audit Committee, to 
evaluate the effectiveness and contribute to the improvement of 
risk management controls and governance processes.

Following the extreme weather conditions experienced at 
Letšeng during the year, the mitigation measures relating to 
business continuity were reviewed and further strengthened 
where necessary.

Given the long-term nature of the Group’s mining operations, risks 
are unlikely to alter significantly on a yearly basis; however, 
inevitably the level of risk and the Group’s risk appetite could 
change. The Board and its Committees have identified the 
following key risks which have been set out in no order of priority. 
This is not an exhaustive list, but rather a list of the most material 
risks facing the Group. The impact of these risks, individually or 
collectively, could potentially affect the ability of the Group to 
operate profitably and generate positive cash flows in the 
medium to long term. The risks are actively monitored and 
managed as detailed on the following pages.

The KPIs, which are grouped into the growth, value creation and 
sustainability of the Group’s strategy on pages 12 to 13 are linked 
to each risk.

MARKET RISKS

 1.   ROUGH DIAMOND DEMAND 

AND PRICES

 u Numerous factors beyond the 
control of the Group may 
affect the price and demand 
for diamonds. 

 u These factors include 

international economic and 
political trends; projected 
supply from existing mines; 
supply and timing of 
production from new mines; 
and consumer trends.

 u The volatility in the market can 
significantly impact the ability 
to generate cash flows and to 
fund operations and growth 
plans. 

 u Market conditions are 

continually monitored to 
identify trends that pose a 
threat or create opportunity 
for the Group. 

 u The Group has flexibility in its 
sales processes and the ability 
to reassess its capital projects 
and operational strategies 
considering existing market 
conditions to preserve cash 
balances. 

 u Strict treasury management 
procedures are in place to 
monitor cash and capital 
project expenditure. 

 u Revolving credit facilities are 

available during periods when 
cash constraints are 
experienced. 

 u Global macro-economic volatility 
and uncertainty and the cautious 
sentiment in the diamond 
market continued to strain the 
rough and polished diamond 
market during 2016. 

 u Letšeng’s high-value diamonds 

continued to be in high demand 
and achieved firm prices. 
 u The price for Ghaghoo’s more 

commercial production 
decreased by approximately 
30% from that achieved at the 
beginning of 2015, and is 
anticipated to remain 
constrained due to projected 
increase in supply for these types 
of goods from new mines 
coming into production in 2017. 
The continued decline in 
Ghaghoo’s prices prompted a 
review by management of the 
financial viability of the 
operation, and post year end, the 
decision was taken to place the 
operation on care and 
maintenance until such time 
that commencing full 
commercial production would 
make economic sense.

OPERATIONAL RISKS

2.  MINERAL RESOURCE RISK 
 u The Group’s mineral resources 
influence the operational mine 
plans. Uncertainty or 
underperformance of mineral 
resources could affect the 
Group’s ability to operate 
profitably.

 u Limited knowledge of the 
resource could lead to an 
inability to forecast or plan 
accurately or optimally, and 
lead to financial risk.

 u With Letšeng being the world’s 

lowest grade operating 
kimberlite mine, the risk of 
resource underperformance is 
elevated.

 u Various bulk sampling 

 u At Letšeng, ahead-of-face drilling 

programmes, combined with 
geological mapping and 
modelling methods 
significantly improve the 
Group’s understanding of and 
confidence in the mineral 
resources and assist in 
optimising the mining thereof.

and discrete production 
sampling programmes initiated 
in previous years continued in 
2016 to better define the 
orebody. In addition, micro- 
diamond sample analysis which 
aims to predict grades at depth 
was also conducted. The 
outcomes of these programmes 
will be used to update resource 
models. A drilling programme 
was approved in 2016 and will 
commence during Q1 2017.
 u During 2016, fewer exceptional 

large, high-value diamonds were 
recovered at Letšeng. Following 
a detailed review of the resource 
and operational processes, it was 
considered that the absence of 
these type of recoveries is due to 
the normal statistical short- term 
variability of the resource and is 
expected to revert to normal 
recovery levels.

 u Resource development at 
Ghaghoo was limited to 
mapping of the geology for the 
underground tunnels. Data 
obtained from mining activities 
was analysed to further 
understand the resource and 
develop the value in the reserve. 
While the asset is on care and 
maintenance, further analysis of 
data will be undertaken to 
improve the knowledge of the 
resource.

3.   A MAJOR PRODUCTION 

INTERRUPTION 

 u The Group may experience 
material mine and/or plant 
shutdowns or periods of 
decreased production due to 
numerous events. Any such 
event could negatively impact 
the Group’s operations and its 
profitability and cash flows. 

 u The Group continually reviews 

 u During 2016, excessive snow fall 

the likelihood and 
consequence of various 
possible events and ensures 
that the appropriate 
management controls, 
processes, and business 
continuity plans are in place to 
immediately mitigate risk.

and severe winds were 
experienced in Lesotho, limiting 
access to Letšeng and damaging 
the Lesotho Electricity 
Company’s infrastructure, 
impacting power to the 
operation. Backup generators at 
the mine were used to mitigate 
the impact, allowing treatment 
plants to continue to operate, 
albeit at reduced rates.
 u The two major production 

interruption risks at Ghaghoo of 
wet underground conditions 
and single access tunnel to the 
underground, continued to be 
managed through water 
management strategies and 
regular monitoring of the 
condition of the access tunnel 
respectively.

éé

4.  DIAMOND THEFT
 u Theft is an inherent risk factor 
in the diamond industry.
 u At Letšeng, because of the 
frequency of high-value 
diamonds and the associated 
low grade, theft can have a 
material impact on Group cash 
flow.

 u Security measures are 

 u The Coarse Recovery Plant at 

constantly reviewed and 
implemented to minimise this 
risk.

Letšeng, with additional security 
features, continued to be 
optimised during the year. 

 u State-of-the-art security 

 u Three independent audits of the 

Growth

infrastructure and 
technologies are invested in 
and supported through 
additional surveillance 
processes.

security systems were 
conducted, the outcomes of 
which resulted in a series of 
findings that provided 
opportunity to further improve 
the security processes at 
Letšeng.

5.  DIAMOND DAMAGE  
 u Letšeng’s valuable Type II 
diamonds are highly 
susceptible to damage during 
the mining and recovery 
process. To reduce such 
damage creates a potential 
upside for the Group.

 u Diamond damage is regularly 
monitored and analysed 
through studies and variance 
analyses.

 u Opportunities to reduce 

damage through 
modifications to the mining 
and treatment process are 
identified for further 
investigation.

 u During the year, five diamonds 
greater than 100 carats were 
recovered.

 u Options are currently being 
assessed to further enhance 
recovery and reduce damage to 
the large-sized diamonds 
through a large-diamond 
specific recovery plant. 

6.  EXPANSION  AND GROWTH
 u The Group’s growth strategy is 
based on delivery of expansion 
projects, premised on various 
studies, cost trends and future 
market assumptions. In 
assessing the viability, cost and 
implementation of these 
projects, risks concerning cost 
overruns and/or  delays may 
affect the implementation and 
execution thereof.

 u Project governance structures 
have been applied to ensure 
that projects are monitored 
and risks managed at an 
appropriate level.

 u Flexibility in the execution of 
projects allows the Group to 
react quickly to changes in 
market and operational 
conditions.

 u At Letšeng a post-investment 
review was completed on the 
Plant 2 Phase 1 upgrade which 
proved that the project achieved 
its objective.

 u In Q4 2016 projects aimed at 
maximising Letšeng’s value 
commenced and included a 
revised life of mine plan, aimed 
at reducing waste tonnes mined 
and further enhancing cash 
flows, and the study of the 
benefits of developing a 
large-diamond specific recovery 
plant.

 u Ghaghoo was downsized during 

2016, necessitated by the 
challenging diamond market for 
the Ghaghoo production.  
Market and operational 
conditions worsened during the 
year necessitated the placing of 
Ghaghoo on care and 
maintenance post year end. The 
viability of this asset will be 
continually monitored to allow 
the Group to react to any 
positive market movements.

incident may occur is inherent 
in mining operations.

 u These risks could impact the 

safety of employees, licence to 
operate, Company reputation 
and compliance with facility

The scenarios tested considered the Group’s revenue, EBITDA, 
cash flows and other key financial ratios over the three-year 
period. Given that Letšeng experienced a paucity of larger high 
quality diamonds in 2016 impacting its revenue and cash flows, 
the scenarios tested included the impact of continued paucity of 
these diamonds over the three-year period. This paucity is 
considered to be due to the normal statistical short-term 
variability of the resource and would be expected to revert to 
normal recovery levels within this three-year period. 

The scenarios tested included the compounding effect of: 
 u a decrease in forecast rough diamond prices from the 

expected reserve prices; and

 u an appreciation of local currencies to the US dollar from 

expected market forecasts.

With the current net cash position of US$3.8 million as at 
31 December 2016 and available standby facilities of 
US$53.3 million, the Group would be able to withstand the 
impact of these scenarios occurring over the three-year period, 
due to the cash-generating nature of the Group’s core asset, 
Letšeng, and its flexibility in adjusting its operating plans within 
the normal course of business. Post year end, the US$25.0 million 
Ghaghoo facility was settled out of available facilities at the 
Company level. 

Based on their robust assessment of the principal risks, prospects 
and viability of the Group, the Board confirms that they have a 
reasonable expectation that the Group will be able to continue in 
operation and meet its liabilities as they fall due over the 
three-year period ending March 2020. 

Viability statement

In accordance with the revised UK Corporate Governance Code, 
the Directors have assessed the viability of the Group over a 
period significantly longer than 12 months from the approval of 
the financial statements. The Board concluded that the most 
relevant time period for consideration for this assessment is a 
three-year period from the approval of the financial statements, 
taking into account the Group’s current position and the potential 
impact of the principal risks documented on pages 18 to 24 that 
could impact the viability of the Group. This period also coincides 
with the Group’s business and strategic planning period, which is 
reviewed annually, led by the CEO and involving all relevant 
functions including operations, sales and marketing, financial, 
treasury and risk. The Board participates fully in the annual review 
process by means of structured board meetings and annual 
strategic sessions. A three-year period gives management and the 
Board sufficient and realistic visibility in the context of the 
industry environment of the Group. 

At Letšeng, the Group’s focus is on organic growth with particular 
emphasis on enhancing efficiencies and optimising expansion 
plans at the operation. At Ghaghoo, following the weak state of 
the diamond market for this category of diamonds, the decision 
has been taken to place the mine on care and maintenance with 
the objective of cash preservation and the option to bring the 
mine into commercial production should the diamond market 
improve for these goods.

For the purpose of assessing the Group’s viability, the Directors 
focused their attention on the more critical principal risks 
categorised within the Market, Operational and Financial risks 
together with the likely effectiveness of the potential mitigations 
that management reasonably believes would be available to the 
Company over this period. Although the business and strategic 
plan reflects the Directors’ best estimate of the future prospects of 
the Group, they have also tested the potential impact on the 
Group of a number of scenarios over and above those included in 
the plan, by quantifying their financial impact and overlaying this 
on the detailed financial forecasts in the plan.

Market review

Despite another challenging year for the diamond industry, prices for the large, high-value 
rough production from Letšeng remained resilient during 2016.

THE GLOBAL ECONOMIC BACKDROP IN 2016
 u Continuing macro-economic uncertainty
 u Slow growth of the Chinese economy
 u Demonetisation in India 
 u Positive economic trends in the USA
 u Reported improvement in commodities markets

THE GLOBAL DIAMOND MARKET IN 2016
Global macro-economic volatility and uncertainty continued in 
2016 and the sentiment in the diamond market remained 
cautious. The strengthening US dollar, slow growth in the Chinese 
economy, demonetisation in India, continued liquidity constraints 
and high levels of polished inventory (particularly in the 
manufacturing sector) continued to plague the diamond market 
during the year, placing downward pressure on both rough and 
polished diamond prices. Despite these challenges, the prices 
achieved for the large, high-value rough production from Letšeng 
remained firm.

Significant drivers of the diamond market during 2016 included:

u Stabilised demand and high inventory levels in China
Notwithstanding indications that the diamond market in China 
stabilised and showed signs of recovery during the year, reported 
inventory levels remained high. This continued to have a negative 
impact on the rough and polished diamond market. 

u The continued US recovery
The economic recovery in the US continued in 2016. This positive 
trend is closely linked to spending on luxury goods, and had a 
positive impact on diamond sales in the US during the year. The 
US remains the largest consumer of polished diamonds, with an 
estimated 45% of world consumption. However, due to diamond 
sales being US dollar denominated, a stronger US dollar 
negatively impacted sales in non-US denominated countries.

u Liquidity and funding constraints
The demonetisation experienced in India in the latter part of 2016 
and the withdrawal of Standard Chartered of its financing of the 
midstream of the diamond market in mid-2016, together with the 
closure of the Antwerp Diamond Bank at the end of 2014, and 
reported high levels of inventory, precipitated the continued 
liquidity and midstream working capital funding constraints 
experienced by the diamond market in 2016. Positively, several 
banks including ABN AMRO, the State Bank of India and more 

recently banks in the United Arab Emirates continue to provide 
funding to the diamond industry and in particular, the midstream 
diamantaires.

u High levels of polished inventory
The reported slowdown in the demand for polished diamonds 
seen in 2016 was mainly a result of slow growth in China; lower 
than expected demand in the US (notwithstanding its reported 
economic recovery); and a delay in expected growth in diamond 
jewellery demand in India. This resulted in high levels of polished 
inventory in the midstream and retail sector of the diamond 
pipeline, negatively impacting the diamond market as the 
diamantaires traded their polished stock at lower margins.

Global supply trends
The ageing and depletion of existing mines will steadily 
decrease the global diamond supply which will be marginally 
offset by limited additional supply from new mines in the 
short to medium term:
 u Rough diamond production has declined considerably 
since peaking in 2005 and is yet to recover to the pre-
global financial crisis levels of approximately 168 million 
carats per annum. 

 u Annual global diamond production is currently in the 

region of 128 million carats and with the introduction of 
several new mines, is expected to peak near 150 million 
carats in the next three to four years. Thereafter a steady 
decrease in supply from 2021 reduces annual production to 
around 110 million carats by 20301.

 u The projected supply from new mines is expected to add 

an additional 26 million carats a year until 2026 and 
thereafter output from these mines is expected to decrease 
to around 16 million carats by 2030. The additional supply 
from these new mines is not expected to compensate for 
the expected growth in demand during the same period.

LOOKING AHEAD
In the short term, the reported high levels of polished inventory 
and the downward pressure on both rough and polished prices in 
the diamond market remains a challenge. However, it is expected 
that the prices for Letšeng’s large, high-value production will 
remain resilient in the short, medium and long term.

GEM DIAMONDS’ MARKET POSITION 
Although not immune to these macro-influences, the large, 
high-value diamond market remained resilient during the year. 
Prices achieved for Letšeng’s large, high-value diamonds ensured 
that the mine retained its standing as the highest average dollar 
per carat kimberlite diamond producer in the world. The Letšeng 
mine places the Group at the top end of the diamond market in 
terms of the size and quality of its large diamond production, with 
its greater than 10.8 carat diamonds accounting for approximately 
75% of its value in 2016.

The Group’s Ghaghoo mine in Botswana produces diamonds of a 
more commercial size, quality and colour, which, although 
diversifying the production of the Group, was negatively impacted 
by the challenging diamond market experienced in 2016.

MEDIUM- TO LONG-TERM OUTLOOK
Demand for rough and polished diamonds is expected to outstrip 
supply in the medium to long term despite the current market 
conditions. The medium to long-term outlook for the diamond 
demand/supply fundamentals are expected to remain favourable 
given the expected rising consumer demand in developed and 
developing markets contrasted with declining supply forecast in 
the medium to long term.

Global demand trends 
Diamond demand is expected to continue to grow in real 
value terms due to:
 u The continued recovery in the US, the major diamond market.
 u The growing international trends to use diamonds across a 
wider range of luxury goods, including jewellery, watches, 
accessories and digital devices.

 u The growing middle and upper classes and the continued 
urbanisation in emerging economies – especially in India 
and China.

 u The continued growth in the number of high-net-worth 

individuals worldwide.

Q & A with the Chief Executive

Clifford Elphick Chief Executive Officer

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements31

While, as I mentioned, the number of exceptional diamonds 
recovered was lower than in prior years, an 11.8 carat pink 
diamond and a 160.2 carat Type II white diamond were recovered. 
These two diamonds, respectively, represent the highest 
US$ per carat price achieved as well as the largest diamond 
recovered for 2016. 

The pink diamond was sold for US$187 700 per carat – making it 
the third highest price per carat achieved for a single Letšeng 
diamond. The 160.2 carat Type II white diamond was sold into a 
partnership arrangement, where Gem Diamonds will participate 
in additional final polished margin. 

Letšeng operation faced during 2016?

Q: Conversely, what were the main challenges the 
A: The robust operational performance of the mine is given 

further credence when you take into consideration the 

challenges presented by factors entirely outside of our control. In 
late July, extreme weather conditions were experienced across 
the Maluti Mountains in Lesotho where the mine is located, with 
excessive snowfall and severe winds limiting access to the mine 
and damaging the national grid power supply to the mine. 
Because of the setbacks that resulted from the severe weather, we 
revised our targets downwards. During this time, Letšeng 
provided accommodation and food to approximately 250 local 
people who were at risk, demonstrating the sense of community 
of the Letšeng team. 

Unfortunately, while the mine was able to achieve its revised 
operational objectives, the lower than expected recovery 
frequency of exceptional, large diamonds nevertheless had a 
significant negative impact on our financial results. The lower 
revenue achieved for the year is a direct consequence of this.

Gem Diamonds’ financial year?

Q: Reflecting on 2016, how would you characterise  
A: Simply put, the year was challenging for both Letšeng 

and Ghaghoo. 

At Letšeng, despite a good operational performance and robust 
demand for its production, the decline in the number of large 
special diamonds recovered impacted on the average price 
achieved per carat for the year. On the other end of the diamond 
spectrum, the depressed market for smaller-sized diamonds 
continued to place pressure on the prices obtained from our 
Ghaghoo operation’s sales. 

The Group’s financial results were adversely impacted by these 
lower effective prices, resulting in an EBITDA of US$63 million for 
the year, 39% lower than in 2015.

Letšeng, what were the highlights for the year?

Q: 2016 was clearly a challenging year. Focusing on 
A: Operationally, Letšeng had a satisfactory year with all 

production metrics achieved within plan and guidance. 

In 2015 the life of mine plan continued to evolve, the 
implementation of which was successful in its objective of 
contributing additional higher-value Satellite pipe ore to the 
processing plants.

During the period, a post-investment review on the Plant 2 
Phase 1 upgrade, completed in 2015, showed that the plant 
capability had improved by 12%, in line with the project 
expectations. The impact of the severe weather experienced 
during the year offset this improved plant capability, however, 
we expect the full benefit of this uplift to be evident in 2017 and 
future years.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements32

Q & A with the Chief Executive continued

Q:  Is there any concern that the low recovery rate of 

exceptional diamonds is indicative of more than 
simply a poor year?

A: No, I don’t believe that’s the case. Following a detailed 

review of the resource and operational processes by our 

geology team, we are confident that, as was the case in 2012 and 
2013, the lower recovery rate is simply due to the normal 
statistical short-term variability of the resource. Letšeng is well 
known for its recovery of these exceptional diamonds and we 
expect this trend to continue.

Meanwhile, we are assessing options to further enhance recovery 
and reduce damage to these diamonds through a large-diamond 
specific recovery plant. As part of the Group’s annual planning 
cycle, a review of the Letšeng mine plan was completed in 
Q1 2017.  This mine plan further optimises the waste mining 
profile, which in turn will improve cash flow.

Q:  The Ghaghoo operation is facing considerable 

headwinds. Please describe the performance and 
prospects for the operation? 

A: I think it’s important to understand that the challenges are 

predominantly due to market conditions. The market for 
small, commercial diamonds remains constrained. At the start of 
2016, we announced the decision to downsize our Ghaghoo 
operation owing to the underperforming smaller-sized diamond 
market. The actions required to reduce tonnage at Ghaghoo were 
completed in 2016 and the operational improvements progressed 
well. Mill modifications yielded positive results with increased and 
improved diamond liberation. Furthermore, the focus on cost 
discipline resulted in reduced operating costs. There have also 
been encouraging recoveries of larger diamonds as mining 
moves into the undiluted portions of kimberlite ore – 
demonstrating the potential of the mine.

Despite the steps taken, ongoing development of the mine in the 
near term has been reviewed. Taking into consideration the 
continued weakness in the market for Ghaghoo’s diamonds, 
which continued to decline from US$210 to US$142 per carat in 
prices achieved, and which we expect to be further exacerbated 
by the increase in supply from three new mines entering this 
particular category of diamond market in February 2017, the 
Group has decided to place the Ghaghoo mine on care and 
maintenance until conditions improve.  This has led to us 
recognising a non-cash impairment charge of US$170.8 million in 
this year’s results.

A decision to place a mine on care and maintenance is a very 
difficult one based on the impact it has on the people that we 
employ at the mine. I would like to acknowledge and thank the 
entire team in Botswana for their tremendous effort and hard 
work to bring this mine into operation. The 20.5 million carats 
contained in the mine body will be mined when prices recover 
and the operation can be economically justified.

Q:  Gem Diamonds is committed to maximising the 

profits received from its diamonds. How does the 
Group do this?

A: It starts with a focus on operational targets to achieve the 

maximum value from our production, balanced with 

ongoing cost discipline to maximise profits. Beyond a focus on 
operational efficiency, we are always looking for ways to create 
additional value. This means limiting diamond damage as well as 
continually investing in downstream activities, such as selecting 
certain high-value rough diamonds for cutting and polishing if 
they do not achieve reserve prices which have been set on 
competitive tender. This, of course, is done through our own 
facilities in Antwerp or by partnership arrangements. This has paid 
off and offered the Group added resilience in the face of the 
challenges experienced.

balance sheet strength?

Q: How have challenges of 2016 impacted the Group’s 
A: We ended 2015 in a strong financial position underpinned 

by strong cash generation from Letšeng and prudent 
capital management over the past few years. While the cash 
resources were depleted in 2016 because of the challenges faced 
during the year, the Group still ended the year in a net cash 
position, demonstrating the strength of our balance sheet, which 
was bolstered by previously implemented revolving credit 
facilities.

ensure safety remains top of mind?

Q: Safety is an ongoing priority. How does the Group 
A: Behaviour-based safety forms the cornerstone of our 

health and safety strategy. We regularly engage with 

employees to better understand our operational processes, in 
that way, we become more efficient and improve the working 
environment. Another way we prioritise the safety and well-being 
of our employees is through our thorough induction procedure 
and the ongoing daily monitoring and reporting of safety 
statistics. 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements33

These systems continue to bear fruit and I’m pleased to report a 
fatality-free year, for the second consecutive year. Regrettably, five 
lost time injuries occurred. Continued emphasis on improving 
safety remains a focus in striving towards our goal of zero harm.

In trying times, it is the difficult decisions we take now that will 
stand us in good stead in the future. At Ghaghoo, we are focused 
on placing the asset on care and maintenance efficiently and as 
cost effectively as possible.

Q:  The Group operations are set in unique locations. 

How does Gem Diamonds manage and minimise its 
environmental impacts? 

A: We understand that our operations are located in sensitive 

ecosystems, rich in biodiversity. It is, therefore, imperative 
that we manage our environmental impacts with a high degree 
of operating discipline throughout the lifecycle of the mining 
operations. During 2016, our environmental teams continued to 
monitor the Group’s ongoing compliance and pursued innovative 
ways of addressing environmental challenges. We are happy to 
report that for the eighth consecutive year, no major 
environmental incidents have occurred across the Group. 

development? 

Q: What is Gem Diamonds’ approach to social 
A: We are committed to contributing positively to the 

economies in which we operate and to supporting the 

sustainable development of the communities we directly impact 
through our operations. We do so through the payment of taxes 
and royalties, as well as through the development and 
implementation of appropriate, sustainable corporate social 
investment projects. 

At Letšeng, corporate social projects are implemented in 
three-year cycles based on needs identified in the community 
through an in-depth needs analysis. For instance, the Botha-Bothe 
vegetable project, which commenced in 2015, continued to make 
a positive and sustainable contribution to community upliftment 
during the year. Ghaghoo continued to contribute towards 
initiatives aimed at improving community access to medical 
services and the upgrading of educational infrastructure.

the Group in 2017? 

Q: Looking ahead, what are the prospects and focus for 
A: We believe the long-term fundamentals for the diamond 

industry are strong. As a Group, our focus will be on 
replenishing cash and strengthening our balance sheet. The 
emphasis for 2017 and beyond remains on maximising our core 
asset – Letšeng. We are committed to reducing diamond damage 
and enhancing the mine plan to improve cash flow. 

We remain confident about the future of Gem Diamonds and its 
strategic positioning to weather the current challenging 
commodity prices and to continue creating value for our 
shareholders and other stakeholders.

Q: Would you like to add anything in closing?
A: I would like to take this opportunity to thank our 

shareholders and stakeholders for their continued support. 
I also extend my sincere gratitude to the Board for their guidance 
and support throughout the year. A special thanks to our 
outgoing Chairman, Roger Davis – your commitment to driving 
Gem Diamonds forward has been instrumental in the Group’s 
success over the years. We wish you well in your future 
endeavours. We are in the final stages of recruiting Roger’s 
successor and look forward to updating the shareholders further, 
ahead of the 2017 AGM.

At the end of February 2017, the Letšeng Chief Executive Officer 
(CEO), Ms Mazvi Maharasoa, retired from the organisation after 
10 years of diligent service. During her tenure, Mazvi has been 
instrumental in driving the successful growth strategy of the 
mine. Mazvi has also been an important role player in the 
establishment of the Lesotho Chamber of Mines. I would like to 
take this opportunity to thank Mazvi for her valued contribution 
to the Group’s success.

Finally, thank you to all our employees – your hard work and 
faithful commitment to the success of Gem Diamonds continues 
to drive us forward.

Balance sheet strength 
withstands tough operating 
and market conditions

The 2016 results were disappointing for the Group when 
compared to the results of previous years. Challenging market 
conditions impacting diamond prices, especially for the Ghaghoo 
type production, and operational headwinds at Letšeng with the 
lack of large, high-value diamond recoveries, had a significant 
impact on revenue, profit and cash. Although cash resources were 
reduced during the year, the Group still ended the year in a 
positive net cash position. 

In response to the challenging operating environment and weak 
state of the market for the Ghaghoo type production in early 
2016, the downsizing of the operation was actioned in Q1 2016. 
Although cost reductions were initiated and plant modifications 
implemented, these positive outcomes were not enough to 
support the operation, considering the continued depressed 
state of the market. With the last tender held in December 2016 
achieving US$142 per carat, down 11% from the first tender of the 
year, the Board made the decision to place the Ghaghoo 
operation on care and maintenance in February 2017 and an 
impairment charge of US$170.8 million was recognised at 
year end.

Although the heavy snow storms and extreme weather 
experienced at Letšeng in July 2016 impacted the operation 
(losing 17 days of production), Letšeng achieved similar 
operational throughput to that of the previous year. However, the 
paucity of the larger high-value diamonds recovered in 2016, 
especially in the second half of the year, significantly impacted 
the overall US$ per carat achieved. Letšeng achieved US$1 695* 
per carat for 2016, with an average of US$1 898* per carat 
achieved in H1 2016 and US$1 480* per carat in H2 2016. The 
reduction in H2 2016 was driven further by the lower volume of 
the higher-value Satellite pipe material mined of 0.7 million 
tonnes compared to 1.0 million tonnes in H1 2016. 

Gem Diamonds remains focused on cost discipline and its 
fundamental goal of extracting the maximum value from its 
resources for long-term shareholder value creation. In light of the 
current year’s results and the reduced cash resources, the Board 
did not approve a dividend for the 2016 results. The Group will 
continue to focus on capital and cost discipline at the operations 
to remain in a position to recommend dividend payments to 
shareholders in the future.

REVENUE
The Group continued its objective of maximising the value 
achieved on rough and polished diamond sales. The Group’s 
revenue is primarily derived from its two business activities, 
namely sales from its mining operations in Lesotho at Letšeng 
and Botswana at Ghaghoo, and additional margin generated from 
its rough diamond manufacturing operation in Belgium. The sales 
generated by Ghaghoo are not reflected in the Group’s revenue 
figures for the current and prior years, but have been set off 
against operating and development costs capitalised to the 
carrying value of the development asset, as the mine did not 
reach full commercial production for accounting purposes by the 
end of the year.

Group revenue of US$189.8 million in 2016 is 24% lower than that 
achieved in 2015. Letšeng achieved an average of US$1 695* per 
carat from the sale of 108 945 carats, which was 26% lower than 
that achieved in 2015 of US$2 299* . This lower US$ per carat is 
largely the consequence of fewer high-quality +100 carat 
diamonds being recovered at Letšeng during the year. 

Ghaghoo sold 47 266 carats during the year for US$7.2 million, 
achieving an average of US$152 per carat for the year compared 
to US$162 per carat in 2015. This fall in prices emphasised the 
weak state of the diamond market for this category of diamonds. 

The Group’s manufacturing operation contributed additional 
revenue of US$5.0 million, comprising US$3.2 million polished 
margin and US$1.8 million as a result of the effect on Group 
revenue of the movement in own manufactured closing 
inventory year on year. 

* Includes carats extracted for polishing at rough valuation.

Royalties consist of an 8% levy paid to the Government of Lesotho 
and a 10% levy paid to the Botswana Department of Mines on the 
value of diamonds sold by Letšeng and Ghaghoo, respectively. 
The Botswana royalty costs were capitalised to the carrying value 
of the Ghaghoo development asset during the year. Diamond 
selling and marketing-related expenses are incurred by the Group 
sales and marketing operation in Belgium. During the year, 
royalties and selling costs decreased by 22% to US$17.2 million, 
mainly driven by the reduction in revenue.

OPERATIONAL EXPENSES
While revenue is generated in US dollars, the majority of 
operational expenses are incurred in the relevant local currency in 
the operational jurisdictions. The Lesotho loti (LSL) (pegged to the 
South African rand) and Botswana pula (BWP) were weaker 
against the US dollar during the first half of the year, thereafter 
strengthening in the second half of the year. The overall weaker 
currencies, positively impacted the Group’s US dollar reported 
costs. Group cost of sales for the year was US$98.8 million, 
compared to US$112.4 million in the prior year, the majority of 
which was incurred at Letšeng.

LETŠENG MINING OPERATION
Operational excellence through proactive cost management and 
enhanced production efficiencies continues to be a key focus at 
Letšeng. Cost of sales for the year was US$97.8 million, down 12% 
from US$110.6 million in 2015, and includes waste stripping costs 
amortised of US$34.7 million (2015: US$47.2 million).

In line with the mine plan at Letšeng, 29.8 million tonnes of waste 
were mined, 24% higher than 2015. Ore tonnes treated were at 
similar levels to 2015, at 6.6 million tonnes, of which 1.7 million 
tonnes were sourced from the Satellite pipe, compared to 
1.9 million tonnes in 2015. The Satellite to Main pipe ratio of 
26:74 for the year was lower than the previous year of 29:71 and 
was partly influenced by the extreme weather conditions 
experienced in 2016. Carats recovered during the year of 108 206 
remained at similar levels to that of the prior year of 108 579.

1  Direct cash costs represent all operating cash costs, excluding royalty and 
selling costs.
2  Operating costs include waste stripping cost amortised, inventory and ore 
stockpile adjustments, and excludes depreciation.

Total direct cash costs (before waste) at Letšeng, in local currency, 
were LSL1 045.4 million compared to LSL972.8 million in 2015. 
This resulted in a unit cost per tonne treated of LSL157.29 relative 
to the prior year of LSL145.64, representing an effective increase 
of 8%. The increase was driven by local inflation of 5%, the one-off 
costs associated with the unexpected weather incident in July 
and an increase in explosive costs due to revised drill patterns (as 
part of the initiative to address diamond damage). These costs 
also include those associated with Alluvial Ventures (the 
contractor operating a third plant at Letšeng) which are based on 
a percentage of revenue and had a 1.4% effect on the overall 
increase. In Q4 2016, a productivity improvement project with the 
aim of increasing mining efficiencies commenced. The initial costs 
thereof were incurred in 2016; the benefits of which will only be 
seen in 2017. 

Operating costs per tonne treated of LSL215.13 were 2% higher 
than the prior year’s cost of LSL210.84 per tonne treated. This 
slight increase is driven by lower waste amortisation costs during 
the year, due to the different waste to ore strip ratios for the 
particular ore processed. During the year, ore was sourced from 
four cuts (compared to two in 2015), two of which had not 
previously been mined. In addition, less ore tonnes were mined 
from the Satellite pipe, which carries a higher rate of amortisation 
charge. The amortisation charge attributable to the Satellite pipe 
ore accounted for 61% of the total waste stripping amortisation 
charge in 2016 (2015: 65%). 

The increase in local currency waste cash costs per waste tonne 
mined of 9% was impacted by local country inflation, longer haul 
distances to mine the various waste cutbacks and the impact of 
the US dollar strength on the cost of the mining fleet. As part of 
the ramp-up of waste tonnes mined, additional larger fleet was 
brought into use in 2016 by the mining contractor. 

GHAGHOO MINING OPERATION
Based on the market conditions at the end of 2015, a decision 
was made in Q1 2016 to downsize the Ghaghoo operation with 
the objective of reducing cash burn. Although most cost 
reduction initiatives were effected, the challenging underground 
mining conditions impacted the anticipated downsized volumes 
and grades achieved. This had a negative effect on the expected 
revenue and together with the further decrease in diamond 
prices, the overall net cash invested (net after sales) in the 
operation for the year was US$14.4 million. This included one-off 
retrenchment costs and costs associated with the creation of the 
buffer zone to prevent sand ingress into the production levels 
following the sink hole that resulted from the caving in late 2015. 
Development costs of US$3.6 million were invested in order to 
access both current and future ore producing tunnels and 
US$2.6 million was invested in sustaining capital.

Based on the 32% reduction in prices achieved over the two-year 
period, the continued weak state of the diamond market for the 
Ghaghoo category of diamonds, the recent strengthening of the 
Botswana pula against the US dollar and with the Group’s focus 
on profitable production, Ghaghoo was placed on care and 
maintenance in February 2017. As a result, an impairment of 
US$170.8 million, representing the total non-current assets on the 
balance sheet, was recognised in the results and disclosed as an 
exceptional item. Following the restructuring and settlement of 
one-off costs, it is planned that the ongoing care and 
maintenance costs will be approximately US$3.0 million per year.

Group financial performance continued

DIAMOND MANUFACTURING OPERATION
The Group generated additional margin on selected high-value 
diamonds through its manufacturing facilities and partnership 
arrangements. The diamond manufacturing operation in Belgium 
contributed US$3.2 million to Group revenue (through additional 
polished margin) and US$2.2 million to underlying EBITDA. 
Extracted diamond inventory on hand at the end of the year was 
US$4.4 million compared to US$6.2 million in the prior year, 
further increasing Group revenue by US$1.8 million. 

UNDERLYING EBITDA AND ATTRIBUTABLE PROFIT 
Based on the operating results, the Group generated an 
underlying EBITDA of US$62.8 million. The reduced EBITDA from 
US$103.5 million in the prior year was driven by the lower 
revenue of US$59.7 million due to the lower US$ per carat 
achieved during the year. Before exceptional items, the profit 
attributable to shareholders was US$17.7 million equating to 
12.8 US cents per share based on a weighted average number of 
shares in issue of 138.3 million. 

The Group’s effective tax rate was 38.2% excluding exceptional 
items, above the UK statutory tax rate of 20.0%. This tax rate is 
driven by tax of 25% on profits generated by Letšeng, withholding 
tax of 10% on dividends from Letšeng and deferred tax assets not 
recognised on losses incurred in non-trading operations.

EXCEPTIONAL ITEMS
Impairment of assets totalling US$172.9 million were recognised 
during the year, of which US$170.8 million relates to impairment 
of the Ghaghoo operation following the decision to place the 
asset on care and maintenance. The balance of the impairment of 
US$2.1 million relates to the closure of the Calibrated operation. 
This operation was set up to use laser diamond shaping and 
cutting technology and machinery as part of the integration of 
the Group’s rough diamond analysis and manufacturing business. 
As part of the Group’s focus on reducing costs and the limited 
ability to develop this beneficiation opportunity in Lesotho, the 
operation was closed. US$3.5 million foreign currency translation 
reserve was recycled through the income statement relating 
to the Calibrated business as the operation was based in 
South Africa. 

After including the effect of exceptional items of US$176.5 million, 
the Group’s attributable loss was US$158.8 million.

As part of initiating cost efficiencies across the Group, the 
manufacturing operation (Baobab) in Antwerp was downsized 
during the year. Although Baobab will continue to provide its 
advanced mapping and rough diamond analysis and 
manufacturing services to the Group and to third parties, in order 
to decrease fixed overheads, the back-end cutting and polishing 
functions were outsourced. 

CORPORATE OFFICE
Corporate expenses relate to central costs incurred by the Group 
through its technical and administrative offices in South Africa 
and head office in the United Kingdom and are incurred in South 
African rand and British pounds. The impact of Brexit on the 
Group was limited to the depreciation of the British pound 
against the US dollar during the second half of the year, reducing 
the costs incurred in the United Kingdom which are US dollar 
reported. Corporate costs for the year were US$11.0 million, 
showing continued decrease from previous years. During the 
latter part of 2015 the Diamond Producers Association was 
formed with Gem Diamonds as a founding member along with 
industry peers. Costs include the increased associated 
membership fees. The 2016 costs include once-off notice costs 
relating to the retirement of an Executive Director. Finding 
innovative ways of reducing diamond damage is a continued 
focus and US$0.5 million was spent in the current year 
investigating alternative processing methods to improve 
diamond liberation. 

The share-based payment charge for the year was US$1.8 million. 
During the year, a new award was granted in terms of the long-term 
incentive plan (LTIP), whereby 1 400 000 nil cost options were 
granted to certain key employees and Executive Directors. The 
vesting of the options to key employees is subject to the satisfaction 
of certain market and non-market performance conditions over a 
three-year period. The share-based payment charge associated with 
this new award was US$0.4 million for the year.

FINANCIAL POSITION AND FUNDING OVERVIEW
The Group ended the year with US$30.8 million cash on hand, of 
which US$28.5 million was attributable to Gem Diamonds and 
US$3.1 million was restricted (2015: US$2.6 million). This restricted 
cash mainly relates to funds reserved for a portion of the future 
repayment of the US$25.0 million secured bank loan facility at 
Ghaghoo. 

The Group generated cash flow from operating activities of 
US$70.7 million before the investment in waste mining of 
US$70.4 million and capital expenditure of US$7.6 million at 
Letšeng and US$2.6 million at Ghaghoo. The capital expenditure 
at Letšeng mainly comprised US$1.8 million for planned dam wall 
rehabilitation, US$1.0 million for the first phase of the mining 
support services workshop and US$0.5 million for the 
reinforcement of the primary crushing area (PCA) structure. 
At Ghaghoo, the capital expenditure mainly comprised 
US$1.1 million for earthmoving equipment, US$0.5 million for 
borehole extension and US$0.3 million extension to the slimes 
dam facilities. 

During the year, Letšeng declared dividends of US$46.5 million, 
of which US$29.3 million flowed to the Company and 
US$17.2 million was paid outside of the Group for withholding 
taxes of US$3.3 million and payment to the Government of 
Lesotho of US$13.9 million for its minority portion.

The facilities held at the Company and Ghaghoo were 
restructured during the year, where the Company’s 
US$20.0 million available revolving credit facility was increased 
to US$35.0 million and the Ghaghoo fully drawn down facility 
was restructured whereby the capital repayments were scheduled 
to re-commence in June 2019. The Group therefore had 
US$53.3 million worth of undrawn and available facilities at the 
end of the year comprising US$35.0 million at Gem Diamonds 
and US$18.3 million at Letšeng. 

Post-year end, the decision to place the Ghaghoo mine on care 
and maintenance impacted the US$25.0 million term loan facility 
and the Group used the revolving credit facility at the Company 
level to repay the loan. In addition, the LSL140 million 

(US$10.2 million) was settled with the final LSL28.0 million 
(US$2.0 million) repaid in February 2017. 

Post-year end, negotiations continued to secure funding for the 
construction of the mining support services complex valued at 
LSL215.0 million (US$15.7 million). This facility has a planned 
tenure of 5.5 years with a 13-month availability period for draw 
down.

DIVIDEND
At the AGM held on 7 June 2016, shareholders approved the 
payment of an ordinary dividend of 5 US cents per share totalling 
US$6.9 million, and equating to 18% of the Group’s 2015 net 
sustainable attributable earnings. In addition, a special dividend of 
3.5 US cents amounting to US$4.8 million was also approved. 
Based on the current market conditions, the lower than expected 
Letšeng revenue, and the impact that it has had on the Group’s 
cash resources, the Board resolved not to propose the payment of 
a dividend in 2017 based on the 2016 results. 

OUTLOOK 
Focus in 2017 will be on cash generation. At Letšeng, the 
implementation of the revised life of mine plan is expected to 
improve cash flows through a further optimised waste mining 
profile. Furthermore, the variability of the resource is expected to 
revert to normal, improving the recovery levels of the larger, 
high-quality diamonds at Letšeng. The benefits to be derived 
from the mining performance improvement project at Letšeng 
and the placing of Ghaghoo on care and maintenance will allow 
for reduced operating costs. These initiatives will drive the 
objective of maximising shareholder returns with the intention of 
recommencing the payment of a dividend in the future.

STRONG OPERATIONAL RESULTS OVERSHADOWED BY PAUCITY OF 
LARGE HIGH-VALUE DIAMONDS

Business overviewManagement reviewOperating reviewGovernanceFinancial statements41

OPERATIONAL PERFORMANCE 
The planned increase in mining production progressed during 
the year, with a 24% increase in waste mining in support of 
increasing the contribution of the higher-value Satellite pipe ore. 
Letšeng treated 6.6 million tonnes of ore compared to 6.7 million 
tonnes of ore in the prior year. A post-implementation review of 
the Plant 2 Phase 1 upgrade (commissioned in 2015) was 
completed during the year, indicating a 12% increase in the plant 
capability. The additional expected tonnes were not realised due 
to power outages caused by a severe snow storm experienced in 
July and August which resulted in both Letšeng and Alluvial 
Ventures’ treatment plants running at reduced capacity for a 
period of 17 days. Ore and waste mined were also negatively 
impacted by the inclement weather conditions, as access to the 
pits was unattainable. Ore sourced from strategic stockpiles on 
surface partially mitigated this impact. Of the total ore treated, 
69% was sourced from the Main pipe, 27% from the Satellite pipe 
and 4% from the Main pipe stockpiles. Letšeng recovered 
108 206 carats at a grade of 1.63cpht, in line with the expected 
reserve grade, at a reserve mine call factor (MCF) of 101%. 

LARGE DIAMOND RECOVERIES
During 2016, the frequency of exceptional larger diamonds 
recovered was lower than expected. Letšeng recovered 
five +100 carat diamonds during the year, compared to 11 that 
were recovered in 2015. Following a detailed review of the 
resource and operational process, it was considered that this 
paucity of large exceptional diamonds was due to normal statical 
short-term variability of the resource, as was experienced during 
2012. The performance of the resource is further detailed in the 
mineral resource management section on pages 46 to 49.

MAXIMISING LETŠENG’S VALUE
Over the past five years, Letšeng has grown to be one of the 
largest open pit diamond mines in the world. This growth has 
required comprehensive capital investment. During this time, the 
mine has continually improved its systems and processes to 
support the additional volumes mined. 

In 2016, a fleet management system was installed to drive further 
productivity improvements. This world-class system will optimise 
the running of the fleet of haul trucks which has again increased 
by seven additional 100 tonne Caterpillar rigid dump trucks in the 
current year. The KPIs generated by this system will provide the 
baseline against which productivity improvements will be 
measured.

During the annual replanning cycle, the sequence of waste 
mining was reviewed with an aim to stabilise the waste stripping 
profile. The outcome of this resulted in an updated mine plan, 
which was completed in Q1 2017, and will reduce the waste 
stripping profile over the next three years and increase the ore 
tonnes available for treatment to 7.0 million tonnes per annum 
(up from 6.0 million tonnes per annum) for the open pit life of 
mine. The valuable contribution from the higher US$ per tonne 
Satellite pipe will increase from 1.6 million tonnes per annum 
to 1.8 million tonnes per annum for the next two years, and 
thereafter will increase to 2.0 million tonnes per annum until 2029. 

The expansion of the open pits has necessitated the construction 
and relocation of an expanded mining support services complex. 
The first phase of this project was completed at a cost of less than 
US$1.0 million. Detailed design of the next phase has been 
completed and the construction thereof, at a cost of 
LSL215.0 million (US$15.7 million), will commence in 2017 once 
project funding has been secured. 

As part of optimising diamond liberation and initiatives aimed at 
reducing diamond damage, the splitting of the front ends of 
Plant 1 and Plant 2 commenced and is due for completion in 
Q1 2017. The splitting of the front ends provides the opportunity 
to dedicate ore treatment through the most suitable plant based 
on geo-metallurgical characteristics. Previously implemented 
workstreams targeting diamond damage reduction have had 
positive results with some exceptional undamaged diamonds 
recovered during the year, in particular, a 160 carat Type II, a 
104 carat Type II and an 11.8 carat pink diamond. Diamonds 
continue to be damaged, and therefore the reduction in diamond 
damage remains a key focus area. To further address this, a project 
has been initiated to investigate the implementation of a large 
diamond recovery capability.

Letšeng continued

To address major sources of downtime experienced during 2016, 
the primary crushing area (PCA) structure was reinforced in 
December 2016, thereby prolonging the PCA’s life and deferring 
major capital expenditure by between eight and 10 years. 
Simultaneously critical maintenance work in Plant 2 was 
completed during which two vertical conveyors, two major 
chutes and a new feed preparation screen was installed. 

As part of Letšeng’s efficiency and cost reduction drive, a mining 
productivity improvement initiative commenced during Q4 2016 
engaging a global mining efficiency and continuous 
improvement consultancy firm to support the mining team on 
site, with the fundamental objective of improving mining 
operational practices and increasing mining equipment utilisation 
and efficiency, with the benefit of reducing operational costs.

These initiatives will further enhance Letšeng’s value proposition 
and are expected to improve the cash flows from the operation. 

RESOURCE DEVELOPMENT
During the year, four micro-diamond samples were treated and 
preliminary interpretation of the results indicated that it may be 
possible to use this technique to determine macro-diamond 
grades. A core drilling programme is scheduled to start in the first 
half of 2017. The programme provides for the drilling of a 
combined 7 540 metres of core in both the Main and Satellite 
pipes. This drilling will provide an enhanced understanding of the 
kimberlite geology below current mining levels. As part of the 
programme it is planned to treat suitable samples of core for 
further micro-diamond analysis. Refer to the mineral resource 
management section on pages 46 to 49 for further details.

SKILLS
The attraction and retention of skills remains an ongoing 
challenge at Letšeng. Working in a remote area and remunerating 
in a globally weak currency remains a challenge when attracting 
skilled employees. Localisation objectives, difficulties experienced 
in obtaining work permits for skilled expatriates and increasing 
competition for skilled personnel from other mining companies in 
Lesotho contribute to the challenges experienced in retaining the 
appropriate skills at Letšeng. 

During the year, several development programmes with 
South African universities and other accredited institutions, for 
the development of Lesotho citizen employees, were successfully 
introduced.

Through the newly established Lesotho Chamber of Mines, 
the sector has conducted extensive engagement with the 
Government of Lesotho to expedite the issuing of work permits 
and facilitating the entry of expatriates into this important sector 
of the economy which in turn will assist in the development of 
mining expertise. A memorandum of understanding has been 
signed between these two parties which will see tangible 
benefits to the industry.

HEALTH, SAFETY, SOCIAL AND ENVIRONMENT (HSSE)
Letšeng retained its ISO 18001 and ISO 14001 certification for the 
second consecutive year. Independent audits were conducted to 
rate the operation’s occupational health, safety and 
environmental management systems against these ISO standards. 
Letšeng is committed to identifying and mitigating the risks to 
the health and safety of its employees, contractors and project-
affected communities (PACs). Regrettably, the operation recorded 
two lost time injuries (LTIs) in 2016, ending a 562-day LTI-free 
period in May 2016. 

As a reflection of the operation’s commitment to safeguarding the 
natural environment in which it operates, Letšeng recorded no 
major or significant environmental incidents for the year. The 
operation considers the protection of its natural environment as 
critical to sustainable success. Numerous environmental projects 
were launched in 2016, including a Bioremediation Project that 
forms part of the overarching nitrate and water management plans.

No major or significant stakeholder incidents were recorded in 
2016 and Letšeng continues to work closely with all its 
stakeholders. PACs, identified through a comprehensive social and 
environmental impact assessment, form an important part of the 
operation’s success. Letšeng worked closely with its PACs during 
2016 to address socio-economic challenges faced by these 
communities.

Approximately US$0.3 million was invested during the year 
towards community projects. This investment was made in 
accordance with a needs analysis and corporate social investment 
strategy that is specific to Letšeng. Education and small and 
medium enterprise developments received the bulk of the social 
investment, with US$0.2 million invested in these two categories. 
In addition to the Botha-Bothe vegetable project, which has been 

successfully running since 2015, the operation also invested in 
another enterprise development project, a dairy project. The dairy 
project is aimed at empowering local farmers by providing them 
with the means to generate income from dairy farming. 

At the end of 2016, 97% of Letšeng’s workforce comprised 
Lesotho citizens.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements45

OPERATIONAL PERFORMANCE
Ghaghoo operated at a reduced production rate during the year 
following the decision to downsize the operation due to the 
depressed state of the market that was experienced in 2015. 

The buffer zone around the sand dilution from the sink hole that 
occurred in November 2015, was successfully created during 
Q1 2016, sterilising approximately 300 000 tonnes of ore.

A total of 1 440 metres of development was completed during 
the year. In total, 217 372 tonnes of ore were treated and 
40 976 carats were recovered, achieving a recovered grade of 
18.9cpht. The recovered grade was below the reserve grade of 
27.8cpht due to the high percentage of coarse breccia dilution 
encountered in the ore extracted near the contact zone from 
Block 2. This was further exacerbated by diamond lock up in the 
DMS tailings and mill oversize material. The gratings and liners in 
the autogenous mill were reconfigured during the fourth quarter 
of the year and the mill operation was optimised to obtain better 
liberation and reduce diamond damage.

The VK-Main phase was successfully sampled and processed. The 
sample achieved a recovered grade of 18.2cpht, being 2% above 
the estimated reserve grade of 17.8cpht. 

During the year, nine diamonds larger than 10.8 carats were 
recovered, of which the largest was a 40 carat diamond. Fancy 
coloured diamonds continued to be recovered, confirming the 
presence of these types of diamonds in the Ghaghoo resource. 

Three sales were concluded during the year, achieving an average 
price of US$152 per carat from the sale of 47 266 carats. 

HSSE
During the year, Ghaghoo’s health, safety and environmental 
(HSE) management system was audited by NOSA (previously 
audited by IRCA) and maintained its four-star rating for its fourth 
consecutive year. Ghaghoo focused on readying its HSE 
management systems for ISO 18001 and ISO 14001 pre-
certification audits. The operation also underwent a ‘Gem Way’ 
internal audit during 2016, following which it was awarded a 
three-star rating.

Ghaghoo focused on building on the safety progress made in 
2015, unfortunately the operation recorded three LTIs during 2016 
ending a 449-day LTI-free period. 

No major or significant environmental incidents were recorded 
during 2016. The operation underwent a suite of environmental 
audits during the year to monitor its compliance with legal and 
social licence requirements. Ghaghoo advanced its study into 
aquifer recharge and commenced with the construction of a pilot 
system that would provide the operation with data to better 
understand the feasibility of aquifer recharge as part of a water 
management strategy.

No major or significant stakeholder incidents were recorded 
during 2016. Ghaghoo used the year to strengthen and formalise 
its corporate social investment strategy. A community needs 
analysis was completed at the start of 2016 and supported the 
social investment strategy implemented by Ghaghoo. 
Furthermore, approximately US$50 000 was invested towards 
maintaining existing corporate social project commitments.

At the end of the year, 97% of Ghaghoo’s workforce comprised 
Motswana citizens. 

CARE AND MAINTENANCE 
The fall in prices of Ghaghoo’s production from US$210 per carat 
in early 2015 to US$142 per carat at its most recent sale in 
December 2016, emphasised the weak state of the diamond 
market for this category of diamonds. The operation has been 
placed on care and maintenance to preserve the value of the 
resource. The focus in 2017 will be to restructure the operation to 
reach a state of full care and maintenance during H1 2017. The 
care and maintenance philosophy is to maintain the asset as a 
going concern to enable effective and efficient 
recommencement of the operation when market 
conditions improve.

Despite recovering these exceptional diamonds, an increase in 
grade and the recovery of a higher quantity of smaller diamonds 
from an area within the southern portion of the Satellite pipe 
during the year, resulted in the average diamond price achieved 
for the year being below expectations. 

Over the past six years, annual revenue from individual diamonds 
larger than 10.8 carats has been consistently 70% to 80% of total 
revenue and, therefore, the operational focus at Letšeng is 
dramatically different to other diamond producers where grade is 
usually the primary metric.

RESOURCE PERFORMANCE
Letšeng 
Letšeng is renowned for producing some of the world’s largest 
and highest-value diamonds. This is mainly as a result of the high 
proportion of exceptional quality, flawless white Type II diamonds. 
This ranks Letšeng as the highest average US$ per carat kimberlite 
mine in the world.

Letšeng’s revenue is highly geared towards the number of 
large, high-value diamonds recovered. The years 2014 and 2015 
were extraordinary in terms of large diamond (greater than 
100 carats) recoveries and the percentage of total revenue 
derived from diamonds larger than 10.8 carats. In comparison, 
the 2016 production year has been characterised by fewer large 
and high-value diamonds. Letšeng’s realised US$ per carat was 
below the 2016 expected reserve prices, and achieved 
US$1 695 per carat compared to US$2 092 per carat. 

Of the 100 highest-value diamonds produced in the past six years, 
only 12 were produced in 2016, negatively impacting the revenue 
at Letšeng.

diamond from Letšeng. In addition, four spectacular diamonds 
recovered during 2016 were ranked in the top 35 of the highest total 
revenue achieved for a single diamond from Letšeng since 2011. The 
aggregate value of these four diamonds was US$22.0 million:

Grade performance
Letšeng’s recovered grade of 1.63cpht was in line with the 
expected grade and achieved a reserve MCF of 101%. Of the total 
ore treated during 2016, 69% was sourced from the Main pipe, 
27% from the Satellite pipe and 4% from the Main pipe stockpiles. 
Historically the Satellite pipe has produced a higher percentage of 
high-value Type II diamonds while Main pipe has produced some 
of the largest and most valuable stones.

Discrete sampling results 
During 2016, discrete sampling within Main pipe and Satellite 
pipe was focused on areas within the KMain, K4, NVK and SVK 
kimberlite domains. This sampling programme will continue into 
2017 and together with the 2017 core drilling programme will 
augment the understanding of the resource. This work is 
enhancing the understanding of the geology and value of both 
pipes at depth.

Resource development
The Letšeng kimberlites are unique and have been a source of 
intrigue for geologists since their discovery. Not only are the 
diamond populations atypical, but the way the pipes were 

formed and their emplacement history is rather unusual. Several 
features of the Letšeng pipes differentiate them from the 
Kimberly-type pyroclastic kimberlites and impact our 
understanding of the distribution of diamonds within the pipes. 

Since mid-2013, the geological team at Letšeng has been working 
with a team of leading kimberlite experts from Canada and 
South Africa to gain a deeper understanding of the relationships 
between the various kimberlite types within each pipe and to 
differentiate high-grade varieties from those with high value 
(containing large and abundant Type II diamonds). During the 
year, previous geological work was reassessed; historical drill core 
was relogged; more detailed studies were undertaken on

indicator mineral abundances and petrography; and the rock 
types at depth were linked with those previously mapped in 
detail in the open pits to update the geological models. 

Although Letšeng demonstrates broad scale consistency year on 
year in terms of price and average stone size for each of the 
kimberlite domains, the objective of the resource development 
programme is to gather data on local variability within each 
domain to improve large stone predictability and calibrate 
expectations of what each domain and subdomain can 
reasonably be expected to yield in terms of grade, average stone 
size, number of +100 carat stones and average price.

Capital was approved in late 2016 for another phase of core 
drilling in both the Main and Satellite pipes to increase the 
density of drillholes down to approximately 300m below the 
current pit floors and further refine the geological models. The 
programme is scheduled to start in the first half of 2017 and 
provides for the drilling of 7 540m of core.

Research was undertaken at University of Alberta on Type II 
macro-diamonds using Fourier Transform Infrared Spectroscopy 
and Secondary Ion Mass Spectrometry to assess a genetic 
relationship between microdiamonds and Type II macro-
diamonds and to test the suitability of the technique as a 
predictor of grade and Type II diamond continuity. This research is 
being expanded in 2017 to study inclusions within the Type II 
macro-diamonds to identify a distinct mantle signature that could 
be used to target kimberlite phases with elevated Type II diamond 
potential based on associated indicator mineral chemistry.

The resource development programme has significantly 
advanced the understanding of the Letšeng kimberlites, the 
details of which are to be presented at the 11th International 
Kimberlite Conference in September 2017. 

No additional resources and reserves were added during 2016. 
The priority for 2016 and into 2017 is firming up on the existing 
resource base and making appropriate operational and 
infrastructural adjustments to extract maximum value. 
Considering the current resource-related work streams in 
progress, no new resource and reserve statement is to be 
declared for 2016. After completion of the drilling programme 
and the associated geological studies on the core are integrated 
into the resource evaluation, an updated resource and reserve 
statement will be issued.

Ghaghoo
Since mining operations began, the focus was on confirming the 
historical estimates of the higher grade VKSE domain. Mining 
started in the south eastern portion of the pipe in the relatively 
undiluted VKSE ore. Mining then progressed towards the central 
zone containing abundant country rock dilution, referred to as the 
brecciated VK or BXVK in the resource statement. This material 
contains primary kimberlite that was diluted with brecciated 
country rock during the emplacement process.

2016 saw a convergence of several factors which served to stress 
the operation, most notably the decline in prices for the types of 
diamonds produced at Ghaghoo. Another contributing factor was 
the mining and processing challenges related to unavoidable 
highly diluted brecciated ore and the substantial proportion of 
lower grade ore from the VKMain.

During 2016 the evaluation of the lower grade VKMain domain 
was initiated. This domain was originally excluded from the 
underground mining reserves due to its low grade. Underground 
development of the tunnel into the VKMain ore commenced in 
July 2016 and sample processing was completed in December 
2016. The sample confirmed the reserve estimates with a 
recovered grade of 18.2cpht, which is 2% above the estimated 
17.8cpht reserve. Additional resource delineation drilling was 
completed during the year in order to confirm geological 
contacts for level one and level two.

PRICES FOR LETŠENG’S HIGH-VALUE DIAMONDS REMAIN FIRM

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements51

The multiple strategic and flexible marketing channels adopted in 
the sale of Letšeng’s high-quality diamonds in 2016 contributed in 
achieving an average price of US$1 695* per carat in a difficult 
and challenging diamond market. The lower Letšeng average 
US$ per carat achieved in 2016 was largely a consequence of 
the paucity of large, high-quality diamonds, rather than any 
notable decrease in demand or weakening of the prices for 
these diamonds. 

Prices achieved for Letšeng’s large, high-value diamonds 
continued to impress with the following prices being achieved:
 u an 11.78 carat pink diamond achieved US$187 700 per carat, 

making it the third highest US$ per carat achieved for a single 
Letšeng rough diamond since Gem Diamonds Marketing 
Services was established in 2010;

 u a 12.31 carat pink diamond achieved US$109 677 per carat; 

and

 u the top two white diamonds of 93.90 and 56.48 carats 
achieved US$56 561 per carat and US$53 451 per carat 
respectively.

The sale of polished diamonds previously placed into strategic 
partnerships contributed additional revenue of US$2.6 million to 
the Group.

An average price of US$152 per carat was achieved for Ghaghoo’s 
production. The downward pressure on prices for the more 
commercial Ghaghoo production seen in 2016, materially 
influenced the sales and marketing strategy for these goods. 
Two of the three Ghaghoo production sales were concluded 
through direct sales, with the aim of maximising the price 
(US$160 per carat and US$155 per carat, respectively). The third 
and final sale for 2016 was concluded by way of open tender with 
viewings in Gaborone and Antwerp, achieving US$142 per carat.

Gem Diamonds continues to invest in its sales, marketing and 
manufacturing operations to pursue ways of maximising 
revenue through a combination of marketing channels, 
including tenders, strategic partnerships, off-take arrangements 
and additional initiatives further along the diamond pipeline.

SALES AND MARKETING 
The Group’s rough diamond production is marketed and 
sold by Gem Diamonds Marketing Services (Belgium) and 
Gem Diamonds Marketing Botswana (Botswana). Letšeng’s 
diamonds are viewed and sold through an open tender in 
Antwerp while Ghaghoo’s diamonds are viewed in both 
Gaborone and Antwerp and, subject to prevailing market 
conditions, are sold either through an open tender or 
direct sale. 

Following viewings by customers in either Antwerp or 
Gaborone, Gem Diamonds’ electronic tender platform allows 
customers the flexibility to participate in each tender from 
anywhere in the world. The tender process is managed in a 
transparent manner. This, combined with professionalism and 
focused customer care and management, has led to a branded 
Gem Diamonds experience, contributing to securing customer 
loyalty, as well as supporting highest market-driven prices for 
the Group’s rough diamond production.

Select rough diamonds from Letšeng which have been 
manufactured into polished diamonds by Baobab 
Technologies (Baobab) are sold by Gem Diamonds Marketing 
Services through direct selling channels to prominent 
high-end customers.

OPERATIONAL PERFORMANCE
During the year, the Group continued to build its premium 
customer base. Currently, the Group has 337 approved and 
registered customers, up from 105 in 2010. Eight large rough 
diamond tenders were held during the year, all of which 
were well attended, with an average of approximately 
130 customers attending each tender. The Group continually 
engages with its customers to better understand their 
challenges and needs and, where possible, accommodates 
these in its marketing strategy. This is evident in the change in 
the number of tenders held in a year reducing from 10 to eight 
(implemented in 2015) and the tenders for the smaller 
production being reduced to one per quarter with 
higher volumes.

ROUGH DIAMOND ANALYSIS AND MANUFACTURING 
Baobab’s advanced mapping and analysis of Letšeng’s large 
exceptional rough diamonds supports the Group in analysing and 
assessing the value of Letšeng’s rough diamonds that are 
presented for sale on tender or sold through other sales channels. 
This ensures that robust reserve prices are set for the Group’s 
high-value diamonds at each tender and informs strategic selling, 
partnering or manufacturing decisions. 

To access the highest value for Letšeng’s top-quality diamonds, 
the Group, through Baobab, selectively manufactures certain of 
the high-value rough diamonds and additionally places other 
exceptional diamonds into strategic partnership arrangements 
with select clients. Baobab also performs analyses and 
management of the manufacturing of large, high-value diamonds 
for third-party customers.

OPERATIONAL PERFORMANCE
The challenging market, especially in the manufacturing sector of 
the diamond industry, necessitated a re-evaluation of Baobab’s 
activities in 2016. Although Baobab continued to provide its 
advanced mapping and rough diamond analysis and 
manufacturing services to the Group and to third parties, a 
decision was taken to outsource the back-end cutting and 
polishing functions to decrease fixed overheads and provide the 
needed services in a more optimal and fit-for-purpose manner. 

During 2016, 33.42 carats of rough diamonds were extracted for 
manufacturing, with a rough market value of US$0.7 million. The 
sale of polished diamonds previously extracted contributed 
additional revenue of US$0.5 million to the Group for the year. The 
lower volume of extractions reflects the flexible marketing 
strategy of the Group which was adapted to consider the current 
challenging polished diamond market and to capitalise on the 
sale of Letšeng’s production of rough diamonds on tender, which 
remained firm during the year.

Sustainable development review

MANAGING THE MATTERS THAT ARE MOST MATERIAL 
TO SUSTAINABILITY FOR THE GROUP
Gem Diamonds considers material matters to be those topics that 
have a direct or indirect impact on its ability to create, preserve or 
erode economic, environmental and social value for the 
organisation, its stakeholders and society at large. Material 
matters, therefore, include risks that must be managed as well as 
opportunities that could be captured to enhance the viability of 
the business in the short, medium and long term. 

This year, Gem Diamonds has organised its material matters under 
five core themes, namely
 u financial and operational;
 u governance and ethics;
 u employees;
 u social; and
 u environmental. 

Each theme makes up a core component of the business and the 
way in which Gem Diamonds sustainably mines diamonds. It is by 
monitoring these matters and remaining nimble in its approach 
to them that the business has continuity and that its impact on 
the places and communities where it operates are positive and 
any damage is appropriately mitigated. 

This sustainable development review provides a summary of the 
information contained in the 2016 Sustainable Development 
Report. Readers are encouraged to read the information below in 
conjunction with the full Sustainable Development Report.

The review highlights the progress made and challenges faced 
during 2016 in pursuing the Group’s sustainable development 
goals. 

FINANCIAL AND OPERATIONAL
Gem Diamonds seeks to create economic value while delivering 
ongoing benefit to all its stakeholders. The Group’s leadership 
approach is one that stimulates and encourages integrity at all 
levels of the business. 

At Gem Diamonds, the need to protect its premium brand of 
diamonds is a key priority. During 2016, Gem Diamonds 
continued its work with the Diamond Producers Association (DPA) 
to enhance and uphold the premium brand of diamonds. During 
the year, the DPA released a campaign titled ‘real is rare’. 

The Group’s sales and marketing team is tasked with developing 
the Letšeng brand and increasing and improving its customer 
base. In a challenging diamond market, the sales and marketing 
team in Antwerp has demonstrated their expertise in achieving 
top prices for Letšeng’s diamonds. 

GOVERNANCE AND ETHICS 
As an organisation whose product derives its value from the 
perception of its consumers, the Group is committed to selling 
diamonds that are produced and distributed in accordance with 
legal and ethical standards. To achieve this, the Group has fostered 
a strong culture of corporate integrity and governance, which 
extends throughout the full business cycle. For more information, 
refer to the Governance section on pages 62 to 109. 

Protecting human rights
Gem Diamonds recognises that diamonds can have a beneficial 
impact on the areas in which it operates when mined and traded 
responsibly. The Group acknowledges, however, that if diamonds 
are mined and sold irresponsibly, they may fuel conflict and 
contribute to human rights violations. 

During 2016, Letšeng and Ghaghoo conducted human rights 
training for 264 employees. Beyond training, the Group enforces 
its policies on the fair treatment of employees through negotiated 
remuneration policies and stringent health and safety practices. 

Gem Diamonds is strongly against human rights violations, 
including gender, age and racial injustices in the workplace. 
Non-discrimination policies are implemented across the Group, 
and stringent policies to prevent child and forced labour are 
adhered to. No cases of child or forced labour involving Gem 
Diamonds have ever been reported. Gem Diamonds also ensures 
rigorous controls are in place throughout its supply chain to 
ensure no slavery or human trafficking occurs, and during the 
year, Gem Diamonds signed a statement in accordance with the 
United Kingdom Modern Slavery Act. Furthermore, none of the 
Group’s operations have engaged in the relocation or 
resettlement of any project-affected communities (PACs) during 
the reporting period. 

Prioritising business integrity 
The Group aims to supply clients with rough and polished 
diamonds while meeting its responsibilities as an ethical and 
accountable organisation. 

The Group complies with the provisions of the Kimberley Process 
and all rough diamond exports are certified in terms of the 
Kimberley Process certification scheme, which aims to eliminate 
the global trade of conflict diamonds. 

This commitment to upholding the highest ethical standards 
ensures compliance with relevant government regulations and 
voluntary codes concerning labelling, product and service 
information. To ensure that the Group’s diamonds reach the 
market through the correct channels, strict controls are applied 
concerning potential clients. Potential clients are subject to a 
screening process, and trade is by invitation only. During the 
screening process, potential clients are assessed to confirm and 
validate their good standing and compliance with internal and 
external anti-money laundering protocols. 

Gem Diamonds maintains the highest levels of transparency and 
integrity during the marketing and sales process. Diamond 
viewing opportunities are made available to clients prior to the 
conclusion of a tender. No warranties in respect of the diamonds 
are issued. Client confidentiality is protected in all instances. All 
tenders are governed by conditions agreed to by all clients. A 
complete list of the winning bids is electronically circulated to all 
tender participants on the close of the tender, ensuring a 
transparent tender process. 

Raising standards across the pipeline 
As part of its initiative to identify and mitigate risk, the Group has 
an established whistleblowing policy, which allows for 
anonymous reporting by employees of any unethical activity 
taking place in the workplace. 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements55

To ensure all those in the supply chain support the ethos of the 
Group, there are procurement policies in place, which drive 
rigorous vetting processes. Potential risk areas are scrutinised, and 
goods and services are only procured from reputable companies. 
Suppliers are required to adhere to the Group’s ethical policies. 

EMPLOYEES 
The Group is committed to providing a work environment that 
actively promotes the health and safety, as well as the 
development and retention of its employees. This is achieved 
through investing in employees’ skills and capabilities and 
promoting equality and diversity in the workforce. 

Providing a safe working environment 
Gem Diamonds’ health and safety management system is based 
on the principles of ISO 18001 and relevant international best 
practice standards. These systems are independently audited on 
an annual basis to ensure compliance and provide the 
organisation with improvement opportunities. 

Gem Diamonds reported a fatality-free year. However, five LTIs 
occurred resulting in a lost time injury frequency rate (LTIFR) of 
0.18, up from 0.00 in 2015. The 2016 Group-wide all injury 
frequency rate (AIFR) was 1.93 – the lowest it has been in the 
history of the Group.

Gem Diamonds believes that concentrated efforts on the 
proactive management of safety will continue to assist in its 
pursuit of zero harm. The number of proactive safety 
management actions implemented throughout the Group in 
2016 amounted to 74 110. 

Attracting and retaining qualified people 
Skills shortages in the mining sector highlight the importance of 
attracting and retaining staff. 

At year end, the Group employed 446 employees and 
1 739 contractor employees, compared with 589 employees and 
1 359 contractor employees during 2015. The average number of 
own employees was 481 (compared with 560 in 2015), while the 
average number of contractor employees for 2016 was 1 650, 
compared with 1 369 in 2015. 

The Group-wide absenteeism rate increased to 3.9 days per 
person in 2016 from 2.0 days in 2015. 

High staff turnover can affect productivity and result in a loss of 
intellectual capital. Monitoring staff turnover helps manage this 
risk and gives an indication of employee satisfaction. The 
Group-wide staff turnover has increased from the 2015 value of 
4.0% to 8.6% in 2016. This percentage takes into consideration 
voluntary turnover and does not include retrenchments. 
Although voluntary turnover increased during the year, this is 
taken to be a normal occurrence in organisations undergoing 
change. The Group will, however, monitor these turnover rates 
and employee satisfaction indicators to ensure, to the best of its 
ability, that quality people are retained.

Group-wide hours per capita vocational training in 2016 has 
increased by 25% from 2015. This increase can be attributed to a 
Group-wide focus on employee development. 

Employees at all the Group’s operations are remunerated in line 
with market-related rates. Gem Diamonds has a policy of 
remunerating male and female employees in the same grade at 
the same level. The lowest-graded employees continue to receive 
higher remuneration than the respective host country’s minimum 
wage standards. 

In Lesotho and Botswana, there is no prescribed minimum wage 
in the mining sector. Therefore, the construction industry 
minimum wage is used as a standard. In 2016, the lowest-graded 
employees at Letšeng and Ghaghoo were remunerated at 24% 
and 11% above this minimum wage respectively. 2% of the 
workforce at Ghaghoo and 0.2% at Letšeng were compensated at 
the operation’s minimum wage . Labour rates are determined in 
line with market-related rates, with external factors such as 
availability of skills, qualification, seniority and work experience 
being taken into consideration. Minimum requirements regarding 
remuneration are contractually stipulated with principal labour 
contractors. 

In addition to basic remuneration, benefits and incentives are 
offered to employees. In 2016, a total of US$36.5 million was 
spent on employee wages, benefits and incentives (2015: 
US$38.9 million), including contractor employees.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements56

Sustainable development review continued

100% of Basotho nationals employed at Letšeng subscribe to the 
mandatory government retirement provision scheme, to which 
Letšeng contributes 7.5% per employee. Permanent employees 
at Ghaghoo receive retirement provisions, as included in their 
remuneration package, while fixed-term contractors receive 
a gratuity. 

All other operations and offices remunerate employees on a 
cost-to-company basis, and employees are free to elect their 
retirement schemes and contributions. 

Gem Diamonds’ mines operate continuously, with shift 
configurations determined by local legislative requirements, as 
well as operational and market demands. 

Providing skills development opportunities for employees 
By investing in developing employees’ skills through the provision 
of training opportunities throughout the Group, employees 
develop personally and professionally. 

The total hours of training provided to employees during 2016 
were: 
 u senior management: 1 086 hours (2015: 691 hours);
 u middle management: 3 122 hours (2015: 3 593 hours); and 
 u non-management: 21 062 hours (2015: 17 464 hours). 

Performing annual career reviews at all its operations remains a 
goal across the Group. There was a small decrease in the 
percentage of career reviews performed during the year from 
23% in 2015 to 22% in 2016 due to downsizing measures carried 
out within the Group. In total 26% of female employees received 
reviews, and 21% of male employees received reviews. 

Ensuring employees remain healthy 
Gem Diamonds is committed to providing an environment that 
actively promotes and supports employee health and well-being. 

Part of the Group’s comprehensive induction programme at the 
mining operations for new employees includes a complete 
medical examination, further promoting its approach to 
employee well-being and care. 

In 2016, Letšeng and Ghaghoo achieved a 100% pre-employment 
medical rate, matching their 2015 figures. 

The Group has implemented a standard process at the mining 
operations for exiting employees, which includes exit medical 
examinations. This further supports Gem Diamonds’ stance on 
complete employee care and is necessary to reduce the Group’s 
long-term exposure to any future health claims. 

In 2016, 7 102 medical cases were recorded across the Group, an 
increase from the 6 447 cases reported in 2015. Of the cases 
reported in 2016, only 7.7% were related to occupational or 
environmental diseases, compared to 8.7% in 2015. The majority 
of cases treated at the mining operations were primary healthcare 
issues, rather than occupational ones. 

Serious disease prevention and management programmes 
continue to expand and mature, resulting in a decreasing number 
of interventions required by the Group’s operations. A total of 

5 769 serious disease prevention and management interventions 
were carried out during the year. The interventions consisted of 
educational interventions and counselling, as well as prevention 
and risk control measures. 

SOCIAL 
The Group aims to contribute positively and sustainably to the 
social and economic state of the PACs and its host countries. 

Ensuring positive stakeholder engagement 
Gem Diamonds recognises that trust is hard earned and easily 
destroyed. Understanding this, the Group strives to foster 
mutually beneficial partnerships with its stakeholders. This is 
primarily achieved through active dialogue with stakeholders, 
focusing on listening and participation at all business levels. 

Each operation has developed a framework for stakeholder 
consultation. These plans are put in place to ensure that all 
stakeholders are engaged and that the PACs are consulted on 
a regular basis. Recognising the cultural and traditional 
individualities of each of the Group’s operational communities 
is essential, and the aim is to function in a manner which is 
transparent and respectful. 

During 2016, no major or significant stakeholder incidents 
occurred at any of Gem Diamonds’ operations. There were also no 
incidents involving any violation of the rights of the indigenous 
people on whose land the Group operates. 

Minimising social impact 
Social and environmental impact assessments are undertaken in 
line with international best practice standards including Equator 
Principles, World Bank and the International Finance Corporation, 
while meeting local requirements. Through this process, any 
negative impacts are minimised and positive opportunities and 
outcomes identified. 

Recognising that mining operations often have an impact on the 
surrounding population, both positive and negative, extensive 
investigations are undertaken into the possible impacts before 
and during mining, and ways of continuing the positive impact in 
these communities, even during the mine closure process, are 
identified. 

Working with communities to understand and meet 
their needs 
Gem Diamonds’ goal is to comply with legal requirements in 
meeting community needs in order to leave a positive legacy. 

In 2016, the Group-wide corporate social investment (CSI) 
expenditure amounted to US$0.4 million (2015: US$0.6 million). 
This decrease can be attributed to a shift in focus at Ghaghoo 
from proactive intervention to project maintenance in line with 
our objective of honouring our commitments to communities 
while managing the pressures of strained market conditions.

The CSI expenditure at Letšeng during 2016 amounted to 
US$0.3 million (2015: US$ 0.3 million). The majority of this 
expenditure was allocated to educational initiatives, followed by 
health programmes, infrastructural development, small and 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements57

medium enterprises, and other donations in support of specific 
charities and events. 

The CSI expenditure at Ghaghoo was approximately US$50 000 
during 2016 (2015: US$0.1 million). Expenditure was focused on 
health and medical initiatives, with contributions to educational 
projects and various donations to other charities and 
corporations. 

Providing a framework for communities to benefit 
themselves 
By employing members of its PACs or by engaging local 
businesses in the Group’s supply chain, a significant positive 
contribution can be made to local communities. These practices 
assist Gem Diamonds in maintaining its social licence to operate 
through job creation and skills development. 

Localisation of the workforce is a priority across the Group. Where 
operations are able to match available skills in the PACs with 
on-site requirements, local recruitment takes place. 

In 2016, 97% of the Letšeng workforce comprised Basotho 
nationals (2015: 97%). At Ghaghoo, 97% of the workforce was 
made up of Botswana citizens in 2016, compared with 98% 
in 2015. 

During 2016, Group in-country procurement totalled 
US$141.2 million (2015: US$152.1 million). Total in-country 
procurement at Letšeng decreased from US$124.7 million to 
US$121.6 million in 2016. PAC local procurement at Letšeng 
decreased to US$1.1 million from US$4.6 million in 2015. The 
procurement from regional communities decreased to US$24.9 
million from US$33.7 million in 2015. Due to the remoteness of 
our Ghaghoo operation, the majority of procurement takes place 
at a national level, rather than on a PAC or regional level. During 
2016, procurement expenditure on a national level decreased to 
US$13.5 million from US$23.7 million. These decreases in local 
procurement spend were in line with a Group-wide focus on cost 
reduction.

Gem Diamonds no longer monitors local contributions for the 
offices and facilities located in Johannesburg and London; a 
decision based on the size and complexity of city-based 
economies. 

ENVIRONMENTAL 
To safeguard the natural environments in which it operates, Gem 
Diamonds invests in various protection measures. In 2016, the 
Group invested a total of US$0.8 million (2015: US$1.5 million) in 
environmental training, specialist consultation, research and 
development, green purchases, and other environmental 
protection measures. 

The Group reassessed its rehabilitation liability during 2016, which 
resulted in an increased liability of US$16.6 million, up from 
US$12.5 million in 2015. The increase can be attributed to an 
updated assessment of the rehabilitation costs that would be 
involved at the Ghaghoo mine. 

For the eighth consecutive year, Gem Diamonds recorded zero 
major environmental incidents. This was also the seventh 
consecutive year that no fines were incurred for environmental 
transgressions or non-compliance. 

During 2016, zero major or significant environmental incidents 
(2015: zero) were reported for the operations. There were 
481 minor environmental incidents reported, compared with 
289 incidents reported in the prior year. This increase can be 
attributed to an improvement in both education on site and a 
drive to ensure issues, however small, are reported as soon as they 
are identified.

Corporate water stewardship has allowed the Group to identify 
and manage its water-related business risks, find ways to mitigate 
its water impacts, and contribute to the sustainable management 
of the catchment areas in which it operates. Water footprint 
studies provide an integrated understanding of water abstraction 
and water use. A water footprint can be defined as a measure of 
freshwater appropriation underlying a certain product, including 
fresh surface water, groundwater incorporated into the product, 
or lost during the manufacturing of the product. 

In 2016, the Group’s total water footprint was 37.8m3/carat and 
1.21m3/tonne treated. The increases were directly related to a 12% 
increase in water usage and 25% decrease in recovered carats. 

The stress water footprint of the Group, that is, the stress placed 
on the water system by mining activity consumption, was 
calculated and water usage at the operations was found to be 
sustainable.

Water quality is constantly monitored at the Group’s operations, 
and any inconsistencies are addressed. At Letšeng, seepage 
occurred from the Patiseng Tailings Storage Facility and the Qaqa 
waste rock dump. The seepage flows into the Patiseng and Qaqa 
river systems respectively. In the Patiseng tributary, a return water 
system has been constructed to capture the seepage below the 
Patiseng Tailings Storage Facility. The Group is currently 
investigating innovative solutions to reduce the nitrate level in 
the water entering the Qaqa water catchment. 

Managing carbon emissions and waste 
The negative effects of carbon emissions, arising from increased 
industrial development around the world, present a long-term 
risk to global climate stability and the Group recognises the need 
to apply every effort in combating this. 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements58

Sustainable development review continued

In 2016, the total carbon footprint for the Group was 
184 765tCO2e (compared to 146 499tCO2e in 2015), primarily 
driven by electricity consumption and mobile and stationary fuel 
combustion. This figure includes the direct GHG emissions 
(Scope 1), energy indirect GHG (Scope 2) emissions, and material 
(Scope 3) emissions, and was calculated with boundaries clearly 
defined by the GHG Protocol Corporate Accounting and 
Reporting Standard. 

The total Group footprint signifies an increase of 26% from 2015. 
This observed increase is the result of a significant increase in 
diesel usage at Letšeng (an increase of 32% in diesel usage for 
mobile combustion and 70% for stationary combustion). The 
combined increase of 32% for liquid petroleum gas (LPG) and 
25% increase in explosives further attributed to this increase. 

All operations have waste management plans to ensure that 
correct waste handling mechanisms are enforced. Volumes of 
mineral waste generated increased at Letšeng during 2016, in line 
with the mine plan. Mineral waste at Letšeng is retained on site in 
structures designed for this purpose. These structures are 
operated in compliance with the host country’s requirements, as 
well as international best practice standards. 

Volumes of mineral waste decreased at Ghaghoo during 2016, 
due to the decrease in mining activity following a decision to 
downsize the operation. 

Setting up and maintaining a mine closure plan, including 
rehabilitation of mining sites and surrounds 
Every mine has a finite life span, and the complete rehabilitation 
of the mine land in the future is required. As such, project 
lifecycles are focused on the eventual restoration of the land. 

The continuous development and review of comprehensive 
rehabilitation plans remained a focus during 2016. The Group 
leases 6 174ha of land, of which 6.8ha were newly disturbed by 
mining activities during the year, bringing the total disturbed land 
leased by Gem Diamonds to 565ha. The Group continued with 
the annual review and improvement of comprehensive 
rehabilitation plans for its mining operations.

Chairman’s introduction to corporate governance

To maintain the best governance system, the Board is committed to 
encouraging integrity and transparency at all levels.

One of the key responsibilities of the Board is to maintain a high 
standard of corporate governance. This is a vital element in 
ensuring our future as a successful and sustainable group. As the 
Chairman, I am ultimately accountable for the application of the 
various provisions of the UK Corporate Governance Code. 

Corporate governance is embedded in the way we organise our 
business, with local boards and sub-committees taking 
responsibility for our operations in local jurisdictions. As a Board, 
we are committed to maintaining regular open dialogue and 
effective communication with all our shareholders, customers, 
employees, suppliers and local communities. 

The Board provides leadership to the Group within a framework 
of controls, which enables risk to be assessed and managed and 
to ensure the necessary financial and human resources are in 
place for the Group to meet its objectives and increase 
shareholder value.

We continue to assess the composition of the Board with the aim 
to obtain an effective balance and diversity of skills and 
experience to meet the Group’s needs. We believe it is important 
that the independence of judgement of the non-Executive 
Directors will support and challenge the executive team on all 
areas of business strategy, risk management and internal controls. 

Directors with a range of skill sets, capabilities and experience 
gained from different geographic and cultural backgrounds, 
enhance the Board by bringing a wide spectrum of experience 
and expertise to the business. We acknowledge the importance 
of diversity, including gender, to the effective functioning of our 
Board. We continue to be supportive of diversity in the 
boardroom. More information about our Board diversity policy 
can be found under the UK Corporate Governance Code 
Compliance Report on page 70.

At present, our Board comprises three Executive Directors and 
four non-Executive Directors representing different nationalities 
and disciplines (the details of which you will find in the biography 
for each individual on the directorate pages 62 and 63). 

I will be standing down as Chairman and resigning as a member 
of the Board at the 2017 Annual General Meeting (AGM). My 
replacement will be announced ahead of the 2107 AGM, who 
I am confident will continue to lead and challenge the Board 
through the next stage of the business.

All Directors will be offering themselves for re-election at the 2017 
AGM. Mr Gavin Beevers was appointed in 2007 and therefore in 
accordance with the Code, he is no longer considered 
independent. Although an extensive search and interview 
process for potential candidates with mining and technical 
experience was undertaken, due to the specific knowledge and 
experience required it proved difficult to find a suitable 
replacement to fulfil the Group’s requirements. At the request of 
the Board, Mr Beevers has agreed to offer himself for re-election at 
the 2017 AGM and remain in post. The Board supports Mr Beever’s 
re-election and has confidence that he will provide continuity to 
the Board given his significant knowledge of the business.

To maintain the highest standard of good governance we will 
continue to ensure the Board and its committees function 
appropriately to enable strong and valuable contribution and 
challenges to the deliberations and that no individual or group 
dominates the Board’s decision-making process. 

During the year, we have continued to be mindful of our duties as 
Directors to manage the Group for the long-term benefit of all its 
stakeholders. We conduct ongoing formal and informal training 
to keep apprised of all legislative and regulatory updates that 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements65

affect how we conduct our business. In 2016, the European Union 
Market Abuse Regime and the Modern Slavery Act 2015 
introduced a number of new processes and procedures that we 
have implemented. 

We undertook a Board evaluation process to follow up the 
matters raised in the 2015 evaluation and to assess the Board’s 
approach to strategy and the ongoing effectiveness of the 
committees and risk management. The evaluation was carried out 
by way of a questionnaire. A detailed description of the evaluation 
process is set out on pages 69 and 70.

In the following pages, you will find overviews of our primary four 
Committees, together with detailed information regarding their 
overall operation within the governance framework.

All four Committees operate within clearly defined terms of 
reference. Each year we review the Terms of Reference for our 
Remuneration, Nominations, Audit and HSSE Committees, 
considering any new provisions introduced in the Code and 
current best practice standards.

We have a robust framework of risk management and internal 
controls which are reviewed quarterly by the Audit Committee. 
A key concern for good corporate governance is to eradicate 
bribery, fraud and corruption. I am confident that we have a 
stringent process in place throughout the Group. The ongoing 
monitoring and review of this process is led by our internal audit 
function. 

Suspected wrong doings which are reported through our 
whistleblowing hotline, are brought to the attention of the Audit 
Committee through our internal audit function, with any 
irregularities being highlighted and actions taken. Following 
investigation, none of the cases reported in 2016 were significant 
and they were resolved without serious consequences.

The Remuneration Committee has been reviewing the Directors’ 
Remuneration Policy to ensure that remuneration policy and 
practices are properly linked to corporate and individual 
performance and to deliver the Group’s strategy on behalf of our 
investors. Every three years the Company is required to put the 
Remuneration Policy to shareholders for approval. The revised 
policy which shareholders will be asked to vote on at the 2017 
AGM can be found on pages 86 to 93. 

The Nominations Committee has been keeping under review the 
composition of the Board and succession planning for both Board 
members and Senior Management positions and it has made 
recommendations to the Board concerning appointments. 

The HSSE Committee continues to ensure health, safety, social 
and environmental policies and practices are assessed and 
reviewed periodically to maintain a high level of relevance and 
appropriateness throughout the Group.

The Board and Committees’ ongoing commitment to good 
governance and best practice principles for the benefit of all our 
stakeholders are demonstrated in the following pages of this 
report.

On a personal note, as I will be stepping down at the 2017 AGM, 
I would like to convey my thanks to the Board and employees of 
the Group. It has been my pleasure serving as your Chairman for 
the last ten years and it is an honour to have been part of a group 
that has continuously demonstrated and delivered excellent 
governance.

UK Corporate Governance Code Compliance

The Board sets standards of conduct which provide an ethical framework for 
the Group’s business functions. 

This report combines the Directors’ Report, the Strategic Report 
and the Group’s compliance with the principles and provisions of 
the UK Corporate Governance Code (the Code). It includes details 
of the key policies, processes and structures that apply to the 
Company. It incorporates sections on the role and work of the 
Audit, Nominations, HSSE and Remuneration Committees in line 
with the Disclosure Guidance and Transparency Rules (DTR).

The Board continues to review and assess all policies and 
practices throughout the organisation considering changes to 
the Code and best practice principles, as well as new EU and UK 
Legislation introduced. The Board also keeps apprised of all 
revisions and market practice recommendations issued by 
institutional investor bodies such as the Institutional Shareholder 
Services, the Institutional Voting Information Service and the 
Pension and Investment Research Consultant. The Company has 
remained below the FTSE 350 for the past four consecutive 
financial years and, therefore, is subject to the provisions 
applicable to the Smaller Company Regime. The Company 
considers that it is compliant with all provisions of the Code, 
unless highlighted otherwise in this report.

BOARD OF DIRECTORS
The role of the Board
The Board is responsible for the overall conduct of the Group’s 
business as follows:
 u setting the Group’s strategy and for the management, 

direction and performance of the business;

 u monitoring and understanding the risk environment in which 

the Group operates;

 u providing accountability to shareholders for the proper 

conduct of the business;

 u safeguarding the long-term success of the Group and taking 

into consideration the interests of all stakeholders; and

 u ensuring the effectiveness of and reporting on the structure of 

corporate governance.

Board composition during 2016

The Board has an agenda for each Board meeting, which includes 
discussion and decision-making surrounding:
 u verbal reports given by the Chairman of each committee on 

the committee’s activities;

 u overall Group strategy, new business, and long-term plans 

incorporating viability assessment;

 u operational reviews;
 u major capital projects;
 u annual business plans and operating plans;
 u the Group’s financial structure, including tax and treasury;
 u annual and half-year financial results and shareholder 

communications;

 u system of internal control and risk management; and
 u administrative matters including corporate governance issues.

The Board sets standards of conduct, which provide an ethical 
framework for the Group’s business functions. While the Board 
focuses on strategic issues, such as financial performance, risk 
management, and other critical business concerns, it also has a 
formal schedule of reserved matters. These reserved matters, 
which are documented in a comprehensive list of authorisation 
levels and prior approval requirements for key corporate decisions 
and actions, are reviewed and approved by the Board regularly. 
The matters reserved were last reviewed in March 2016.

While all Directors have equal responsibility in terms of the law for 
managing the Group’s affairs, it is the role of the executive 
management to run the business within the parameters 
established by the Board and to produce clear, accurate and 
timely reports to enable the Board to monitor and assess the 
Group’s performance. The executive management draws on the 
expertise and experience of the non-Executive Directors.

All Directors are free to express their views and may ask that these 
be recorded in the minutes where appropriate.

The non-Executive Directors possess a range of experience and 
competencies and bring independent judgement to bear on 
issues of strategy, performance and resources that are vital to the 
success of the Group.

With the exception of Mr Beevers, the other non-Executive 
Directors are regarded as independent by the Board as defined in 
the Code, as was the Chairman on his appointment.

reserved for the Board. The remaining two Committees (Standing 
and Share Scheme) facilitate the administration of the Board’s 
delegated authority. Following the introduction of the EU Market 
Abuse Regulations in July 2016, an internal committee was set up 
to identify, control and disseminate inside information and to 
ensure set procedures and processes are in place and in line with 
EU legislation and financial conduct authority (FCA) regulations.

Board and Committee meetings
Five scheduled Board meetings and one special meeting of the 
Board were held during 2016, all in the United Kingdom. 
Attendance by Directors at Board and Committee meetings is 
shown below.

In the event that Board approval is required between Board 
meetings, Board members are emailed the details, including 
supporting information in order to make a decision. The decision 
of each Board member is communicated and recorded at the 
following Board meeting.

There are six formally constituted Committees of the Board, each 
of which have specific terms of reference. Those for the Audit,

Non-Executive Directors’ meetings
Before each scheduled Board meeting, the non-Executive Directors meet independently of the Executive Directors, in accordance with the 
practice adopted by many listed companies. During the year, four such meetings were held.

Chairman and Chief Executive Officer
A clear separation is maintained between the responsibilities of the Chairman and the Chief Executive Officer. This separation was 
established during 2007 with the appointment of Roger Davis as Chairman.

The Chairman is responsible for creating the conditions for the effective working of the Board. The Chief Executive Officer is responsible for 
the leadership, operations and management of the Group within the strategy and business plan agreed by the Board. Their individual 
responsibilities, together with the responsibilities of the Senior Independent Director (SID) and non-Executive Directors are detailed on the 
following pages.

BOARD SKILLS, BALANCE AND INDEPENDENCE
As a mining company, the efficiency of the day-to-day operations, 
in both the medium and long term, is essential to the Group’s 
progress in producing shareholder value. 

Knowledge of the diamond industry is crucial to foster new 
business opportunities and to enhance the Group’s operations in 
cutting and polishing and sales and marketing strategies.

Knowledge of financial markets are also necessary to ensure 
fulfilment of the Group’s strategy. The biographies, which can be 
found on pages 62 and 63, provide more information on each 
Director’s competencies. All Directors allocate sufficient time to 
the Group to fulfil their responsibilities effectively.

The Company complies with the requirement of the Code that 
there should be a balance of Executive and non-Executive 
Directors so that no individual or group can dominate the Board’s 
decision-making.

Non-Executive Directors should be independent in character and 
judgement. All four non-Executive Directors are considered by the 
Board to be independent of management and the Group. In 
applying the independence test, the Board considers relationships 
with management, major shareholders, subsidiary and associated 
companies and other parties with whom the Company transacts 
business against predetermined materiality thresholds.

The letters of appointment for the non-Executive Directors and 
the contracts of the Executive Directors are available for 
inspection at the place of business of the Company in London.

The Board annually reviews the composition and chairmanship of 
its primary Committees, namely the Audit, Remuneration, 
Nominations and HSSE Committees.

APPOINTMENTS AND RE-ELECTIONS TO THE BOARD 
(SEE ALSO BOARD DIVERSITY ON PAGE 70)
The Code requires there to be a formal, rigorous and transparent 
procedure for the appointment of new Directors, which should 
be made on merit, against objective criteria and with due regard 
to the benefits of diversity on the Board. Since 2007, recruitment 
to the Board has been based on recommendation; therefore, no 
outside consultants have been engaged. The Board currently 
comprises a broad and highly relevant skill set and the 
Nominations Committee will continue to make appointments 
based on merit while considering diversity and the specialist skill 
set which is required by the business.

The Nominations Committee’s section of this report is set out on 
pages 80 and 81.

It is required that all Directors retire at the AGM and, if appropriate, 
offer themselves for re-election in accordance with Code 
provision B.7.1. This practice will continue for future re-elections. 
The Nominations Committee has considered and concluded that 
the Board has demonstrated commitment to its role. The 
committee is also satisfied that the collective skills, experience, 
background and knowledge of the Company’s Directors enables 
the Board and its Committees to conduct their respective duties 
and responsibilities effectively.

CONTINUING BOARD DEVELOPMENT, INDEPENDENT 
PROFESSIONAL ADVICE AND THE COMPANY 
SECRETARY
Board evaluation
Aim
The Board understands the importance of ensuring that excellent 
standards of behaviour and governance are maintained, not only 
by the Directors, but integrated through all levels of the Group.

One of the overarching objectives of the 2016 Board evaluation 
was to carry out a comprehensive review on the effectiveness of 
the Board, not only as a unit, but also to assess and evaluate the 
contributions made by individual Directors.

The Board evaluation exercise looked at the composition of the 
Board and Committees of the Board; conduct and decision-
making; how strategy is approached and addressed; risk 
management, management information and reporting; training, 
development and succession planning; and internal and external 
communication.

It also evaluated specific issues raised in the 2015 evaluation, such 
as succession planning, risk management and external 
communications.

Approach
In line with best practice on Board evaluation, as set out in 
provision B.6.2 of the Code, the Board appointed Bruce Wallace 
Associates to undertake an externally facilitated independent 
review of Board effectiveness during November and December 
2016. The scope of the 2016 evaluation review was agreed with 
the Chairman and Company Secretary and implemented by 
means of a questionnaire. The questionnaire was sent to each 
Director and their responses were collated by Bruce Wallace 
Associates who then presented their analysis, findings and 
recommendations in a report to the Board.

Analysis
The report from Bruce Wallace Associates to the Board noted that 
considerable progress had been made addressing 
recommendations in the 2015 Board evaluation. In particular, risk 
management and external communications were identified in 
the 2016 Board evaluation as the two main areas where the Board 
had performed well. In particular there had been an improvement 
in the reporting and communication of risk management.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements70

UK Corporate Governance Code Compliance continued

The Nominations Committee spent a substantial amount of time 
focusing on Board and Senior Management succession planning 
and meeting with potential candidates to ensure the composition 
of the Board remained ‘fit for purpose’ and in line with good 
governance standards.

In addition, risk management was categorised as an ongoing item 
on the agendas of the scheduled Board and Audit Committee 
meetings with regular updates and assessment reports being 
received from the external auditors and the internal audit 
control team.

Next step
The findings and recommendations have been discussed with the 
Board by the Chairman. The Board agreed that continued focus 
on developing succession plans was key. The Board also 
confirmed that internal communications would also be 
considered for further improvements.

Independent advice 
All Directors are aware that they may take independent 
professional advice, at the expense of the Company, in the 
conduct of their duties, subject to prior consultation with the 
Chairman. Furthermore, all Directors have access to management 
and the advice and services of the Company Secretary. The 
Company Secretary is accountable to the Board for ensuring that 
all governance matters are complied with and assisting with 
professional development as required.

Board-approved arrangements ensure that new Directors receive 
a full, formal and tailored induction upon joining the Board. In 
addition, ongoing support and resources are provided to 
Directors, enabling them to extend and refresh their skills, 
knowledge and familiarity with the Group. Professional 
development and training is provided through three measures:

Company Secretary 
An independent firm of Chartered Secretaries in Public Practice 
advises the Company Secretary. Bruce Wallace Associates is 
engaged to ensure that all company secretarial and governance 
issues are attended to and the Board is kept apprised of all 
compliance and best practice matters throughout the year. 

Bruce Wallace also attended to the Board evaluation exercise 
in 2016.

CONFLICTS OF INTEREST
The UK Companies Act requires Directors to avoid any situation 
where they may have a direct or indirect interest that conflicts, or 
may conflict, with the Group’s interests, unless approved by the 
non-interested Directors. In accordance with this Act, the 
Company operates a procedure to ensure the disclosure of 
conflicts and, if appropriate, for the consideration and 
authorisation of them by non-conflicted Directors. The Board 
maintains a register of ‘conflicts of interest’ that it reviews annually 

(most recently in March 2017). The Company voluntarily complies 
with this requirement.

DEALINGS IN SHARES AND THE EU MARKET ABUSE 
REGIME
The Company has revised its Share Dealing Policy and reporting 
procedures in line with the EU Market Abuse Regulations 
implemented in July 2016 (Regulations). The Directors and Senior 
Executives carried out formal training and processes were put in 
place to ensure all persons discharging managerial responsibilities 
and their persons closely associated and insiders (as defined in 
the Regulations) were informed of their obligations and sanctions 
for non-compliance under the new Regulations.

DIRECTORS’ REMUNERATION
While the Board is ultimately responsible for Directors’ 
remuneration, the Remuneration Committee, consisting of 
independent non-Executive Directors, is responsible for 
determining the remuneration and conditions of employment of 
Executive Directors, as well as the Chairman. The Directors’ 
Remuneration policy which will be put before shareholders for 
approval at the 2017 AGM has been reviewed by the 
Remuneration Committee and Kepler, the remuneration 
consultants. The policy has been updated in line with market 
practice and includes such provisions as ’malus’ and ‘clawback’ as 
well as shareholding guidelines for Executive Directors. The details 
of all Directors’ remuneration are covered in the Directors’ 
Remuneration Report and the Annual Report on Remuneration 
on pages 94 to 104.

BRIBERY ACT
In 2015, Group internal audit carried out a review of the Anti-
Bribery and Corruption Policy to ensure continued compliance 
with the UK Bribery Act. The policy was updated, in consultation 
with the Group’s legal advisers, Linklaters, to incorporate the three 
areas of improvement identified during the review, thereby 
ensuring the policy retained robust compliance and diligence 
procedures. The Board approved the updated Anti-Bribery and 
Corruption Policy in June 2016 which has now been rolled out to 
all operations.

The Group’s terms of business require all customers and third 
parties with whom business is transacted to adopt the same zero 
tolerance approach to bribery and corruption as implemented by 
the Board.

BOARD DIVERSITY
The Board continues to support diversity and strives to improve 
the gender balance within the Group with an increasing number 
of suitably qualified females being employed at senior levels 
throughout the organisation.

More information on gender-based employment is contained in 
the Sustainable Development Review on pages 55 and 56.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements71

COMMUNICATION OF BUSINESS DEVELOPMENT 
DURING THE YEAR
Detailed information on the Group’s business developments and 
projects can be found on the Company’s website in the investors 
section, where all published information and shareholder 
communication is available. This includes trading updates; 
year-end and half-year results; resource and reserve statements, 
and all other announcements.

ACCOUNTABILITY AND AUDIT
Information and financial reporting systems
The Board is conscious of its responsibility to present a fair, 
balanced and understandable assessment of the Group’s position 
and prospects and is satisfied that the Strategic Report on pages 
2 to 59 has met this obligation. The Responsibility Statement of 
the Directors in respect of the Annual Report and Accounts is set 
out on page 112.

The Board is supplied in a timely manner with information in the 
form and of a quality appropriate to enable it to discharge its 
duties. Financial reporting to the Board is continuously modified 
and enhanced to cater for changing circumstances. The Group’s 
comprehensive planning and financial reporting procedures 
include detailed operational business plans for the year ahead 
and a three-year rolling plan. The Board reviews and approves the 
Group’s annual business plan.

These are prepared in co-operation with all Group functions 
based on specified economic assumptions. Performance is 
monitored and relevant action taken throughout the year 
through monthly reporting of KPIs and updated forecasts for 
the year, together with information on key risk areas.

In addition, routine management reports on an operational and 
consolidated basis, including updated forecasts for the year, are 
prepared and presented to the Board. These reports form the 
cornerstone of the Group’s system of internal control. Detailed 
consolidated management accounts, as well as an executive 
summary, are circulated prior to each scheduled Board meeting. 
Between Board meetings, summary update reports covering 
matters such as operational performance, sales results, cash flow 
and progress on strategic issues are circulated to Board members 
and Senior Executives.

Internal control
The Board of Directors has responsibility for the Group’s overall 
approach to risk management and internal control, which are 
embedded in all key operations. In accordance with the Guidance 
on Risk Management, Internal Control and Related Financial and 
Business Reporting Guidance published by the Financial 
Reporting Council in September 2014 (the Risk Guidance), the 

Board has defined the processes adopted for its ongoing 
monitoring and assessment and relies on reviews undertaken by 
the Audit Committee throughout the year, as well as the approval 
of the Annual Report and Accounts. In addition, regular 
management reporting and a balanced assessment of key risks 
and controls, is an important component of Board assurance.

The principal aim of the system of internal control is the 
management of business risks that significantly threaten the 
fulfilment of the Group’s business and strategic objectives, with a 
view to enhance the value of shareholders’ investments and 
safeguarding assets. The internal control systems have been 
designed to manage, rather than eliminate, the risk of failure, to 
achieve business objectives and to provide reasonable but not 
absolute assurance that the Group’s business objectives will be 
achieved within the risk tolerance levels identified by the Board. 
The Directors have reviewed the effectiveness of the system of 
internal control. For the review, the Audit Committee considered 
reports dealing with internal audit plans and outcomes, as well as 
risk logs and sign-off from external audit and management 
representations. These did not reveal any significant findings or 
weaknesses. A full report of the work carried out by the Audit 
Committee on behalf of the Board is set out in the Audit 
Committee Report on pages 74 to 79.

Internal audit
The Group internal audit function, as an independent assurance 
provider, is an important element of the overall process by which 
the Audit Committee and the Board obtain the assurance it 
requires that risks are being effectively managed and controlled.

Group internal audit, reporting directly to the Audit Committee, is 
responsible for co-ordinating the Group’s risk-based approach to 
internal audit and to evaluate the effectiveness and contribute to 
the improvement of risk management, controls and governance 
systems.

A risk-based internal audit plan for 2016 was approved by the 
Audit Committee. The risk-based audit plan covers all operating 
units, focusing in particular on the principal risks. It involves 
discussions with management on the risks identified in the local 
and Group risk registers, emerging risks, operational changes, 
capital projects and related internal controls identified in the risk 
self-assessment process. Findings and agreed actions are reported 
to management and the Audit Committee.

UK Corporate Governance Code Compliance continued

Internal audit services are provided by means of a co-sourced 
agreement with KPMG managed through the Group internal 
audit function. The objective of the co-sourced agreement is that 
KPMG will perform certain internal audits on behalf of the Group 
internal audit as and when required. No such services were 
required during the current year.

delegates its authority to the Board for completeness. The Audit 
Committee and the Board, where appropriate, are kept informed 
on progress against the plans and any significant changes to 
review the risk profile. This enables the suitable management and 
non-Executive Directors to holistically review the risk, mitigate 
and implement controls as necessary.

External audit
A principle of the Code is that the Board should establish formal 
and transparent arrangements for considering how it should 
apply the financial reporting and internal control principles and 
for maintaining an appropriate relationship with the Group’s 
external auditors, EY. These responsibilities are delegated to and 
discharged by the Audit Committee, whose role is defined on 
pages 74 to 79.

RISK ASSESSMENT AND MANAGEMENT
The Board, through the Audit Committee, considers effective risk 
management as an essential element of professional 
management and has implemented robust risk assessment and 
internal control systems across the Group.

In accordance with the Risk Guidance, a process has been 
established for continually identifying, evaluating and managing 
the Group’s principal risks. The Group’s Risk Management Policy 
aims to cover and review all important risks faced by the Group, 
including, but not limited to, operational, financial, commercial, 
legal, regulatory and compliance risks, which could undermine 
the Group’s ability to achieve its strategic and business objectives.

These risks are monitored continually and formally reviewed 
annually. A more comprehensive report of the Group’s principal 
risks and how these are managed and/or mitigated can be found 
on pages 18 to 24 of the Strategic Report.

The Company has a value-driven approach to meet its objective 
of ensuring it operates in a stable environment. Through 
monitoring the locations in which we operate, enhancing the 
Group’s assets and protecting employees and the surrounding 
ecosystem, the Group is able to uphold its processes in turn 
creating greater shareholder value and enhancing the Group’s 
moral reputation.

The Group’s operations perform regular risk assessment reviews 
and maintain risk registers. Objectives in the business plan are 
aligned with risks and a summary of the key risks, related internal 
controls, accountabilities and further mitigating actions are tabled 
and approved by the Audit Committee. The Committee at times 

INVESTMENT APPRAISAL
Capital expenditure is managed through a budgetary process and 
authorisation levels. For expenditure beyond specified levels, 
detailed written proposals are submitted to the Board. There is an 
approval procedure for investment, which includes a detailed 
calculation of return based on current assumptions that are 
consistent with those included in management reports.

Post-investment reviews are carried out after the project is 
completed and, for material projects, steering committees are 
established to monitor the progress against the approved plan. 

Commercial, legal and financial due diligence is carried out, using 
external consultants as appropriate, in respect of acquisitions and 
disposals.

WHISTLEBLOWING PROGRAMME
The Company has formal means of reporting suspected fraud, 
corruption and irregularities via independently operated and 
confidential toll-free phone hotlines in each country in which the 
Group operates. Employees can report any breach of the Group’s 
business principles, including, but not limited to, bribery, breaches 
of ethics and fraud.

All incidents reported are fully investigated, and the results are 
reported to the boards of local operations and the Group’s Audit 
Committee. To raise awareness of the hotline throughout the 
Company, literature is issued to employees detailing the 
whistleblowing tool and relevant contact details. Group internal 
audit periodically reviews the design and effectiveness of the 
hotline and reports the results to the Audit Committee.

The whistleblowing reporting process was reviewed in 2016 to 
strengthen the independence of the process whereby all 
whistleblowing incidences reported are distributed by the Group 
internal auditor and Company Secretary for investigation by the 
relevant operations. In addition, the access of automated 
reporting systems was enhanced.

The Board is satisfied that the whistleblowing programme is 
being utilised in the correct manner by concerned individuals and 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements73

that all queries raised during the year have been properly 
investigated and reported.

DIALOGUE WITH SHAREHOLDERS
Communication with industry analysts, institutional investors and 
shareholders is of great importance to the Board. Understanding 
the views of our stakeholders and shareholders has proven to be 
highly beneficial to the Group. The responsibility of investor 
relations is that of the Chief Legal and Commercial Officer, 
Glenn Turner, who is based at the Company’s London office. 

Investor seminars and analyst presentations, including those 
following the Group’s announcement of the year-end and 
half-year results are available as webcasts and other presentations 
made to institutional investors and at external events are available 
on the Company’s website. 

Any concerns raised by shareholders in relation to the Group and 
its affairs are communicated to the Board and a summary of 
shareholders’ views are tabled at each Board meeting.

Glenn Turner keeps in contact with the Company’s institutional 
and other shareholders, as well as industry experts on a regular 
basis. It is his task to ensure there is a continuous flow of reliable 
information between the Company and its investors. Glenn Turner 
is frequently invited to speak at National and International 
Diamond Mining Forums and the Investor Relations team 
organise regular site visits to Letšeng for both investors and 
analysts.

The Executive Directors conduct quarterly roadshows to engage 
with several of the Group’s larger investors creating a suitable 
platform for them to express any concerns.

The shareholder base comprises 138.4 million issued ordinary 
shares of US$0.01 each. There are 187 institutional shareholders 
that hold 126.3 million shares (91%) and 370 private shareholders 
who hold 12.1 million shares (9%).

The Company’s Senior Independent Director, Mike Salamon, is 
available to shareholders if contact through normal channels fails 
to resolve their concerns, or if such contact would be 
inappropriate.

CONSTRUCTIVE USE OF THE AGM
The Code strongly encourages boards to use the AGM to 
communicate with all investors. All Directors attend the AGM, and 
shareholders are invited to ask questions during the meeting and 

to meet Directors after the formal proceedings have closed. 
Shareholders attending the Company’s next scheduled meeting 
will be advised as to the level of proxy votes received, as well as 
the percentages for and against in respect of each resolution.

If the Board considers that a significant proportion of votes have 
been cast against any resolution, the Directors will explain how 
they intend to engage with shareholders to assess their concerns.
The results of the resolutions will be announced through the 
Regulatory News Service and on the Company’s website. 

All shareholders can access the Group’s annual and half-year 
reports; trading updates; and other published information about 
the Group through the Company’s website. 

Details of the resolutions to be proposed at the AGM can be 
found in the Notice of AGM. In accordance with the Code, the 
Notice of AGM and relevant papers will be sent to shareholders a 
minimum of 20 business days before the meeting. The 2017 AGM 
will be held on Tuesday, 6 June 2017.

Audit Committee

TERMS OF REFERENCE 
The Audit Committee’s Terms of Reference were updated in 
2015 in line with the new provisions introduced by the Code 
applicable to the smaller company regime. These were again 
reviewed in March 2017 to ensure they continue to be fit for 
purpose and in line with best practice and governance principles. 
They can be viewed on the Company’s corporate website. 

MEETINGS
Five meetings of the Audit Committee were held in 2016. The 
Chief Executive Officer, the Chief Financial Officer, the Group’s 
internal auditor, and a representative of the Group’s external 
auditors attend each meeting by invitation. Other Directors of the 
Company and Senior Executives may also attend by invitation to 
speak, but not vote, at a meeting. The full Committee also met 
with the Audit Partner without the Executive Directors present 
during the year. Mr Lynch-Bell, as Chairman of the Committee, 
allocates a significant amount of time to this role. In addition to 
chairing formal meetings of the Committee and attending 
sessions with the external auditors, he travelled to Johannesburg 
in 2016 where he met with the Chief Financial Officer and the 
financial team, as well as the Group internal auditor, in order to 
discuss the financial controls and audit activities of the Group. 
A further visit in February 2017 was supplemented with a visit to 
the Group’s operation in Lesotho. Similarly, Gavin Beevers carried 
out site visits during the year to the Group’s operations in Lesotho 
and Botswana, thereby gaining an update to operational matters 
and activities on the ground. Such meetings and site visits enable 
the Chairman and the Committee to uphold a comprehensive 
understanding of corporate and finance developments and 
activities, any associated risks, as well as the controls in place at 
the operations. Following each meeting, the Committee 
communicates its main discussion points and findings to 
the Board.

ROLE AND ACTIVITIES 
The principal functions, in line with the Committee’s Terms of 
Reference, are listed below, along with the corresponding activity 
and performance during 2016. 

Michael Lynch-Bell, Chairman

The Committee comprises:

 u MD Lynch-Bell – Chairman

Role

Activities in 2016

To provide advice to the Board 
on whether the Half-yearly 
Report and Annual Report and 
Accounts, are fair, balanced and 
understandable and to monitor 
the integrity of the published 
financial information of the 
Company and review and 
report to the Board on the 
significant financial reporting 
issues and judgements made in 
connection with the 
preparation of the published 
financial information of the 
Company

To review the effectiveness of 
the internal control and risk 
management processes and 
provide input to the Board’s 
consideration of risk and risk 
appetite

To review the adequacy of the 
Company’s whistleblowing 
system, controls for ethical 
behaviour and prevention of 
bribery, and procedures to 
detect fraud 

The Committee formally reviewed the Group’s Annual Report and Half-yearly Report and 
considered that they present a fair, balanced and understandable assessment of the Group’s 
performance and prospects and provide information necessary for shareholders to assess the 
Company’s performance, business model and strategy.

The Committee reviewed the key auditing and financial reporting matters which typically focused 
on areas of significant judgement, estimation or accounting policy selection. These areas of focus 
were assessed through discussions with the Group’s Audit Partner and Group CFO, ahead of and/
or during Committee meetings, in which the Committee, where appropriate, challenged the basis 
for such judgements and estimates. Details of the significant matters considered by the 
Committee in respect of the 2016 Half-yearly and Annual Report are set out on pages 76 and 77.

The Committee reviewed and assessed the systems and processes in place required to formulate 
the Viability Statement and support its conclusions and recommended the statement issued in 
the Annual Report to the Board for approval. 

The Committee considered institutional comments raised on previous Annual Reports for 
relevance and incorporation into subsequent Annual Reports.

Further published information which was reviewed by members of the Committee included the 
following:
 u quarterly trading announcements published; and
 u report on payments to governments for the year ended 31 December 2015, being a new 

report requirement to satisfy the requirements of the Disclosure and Transparency Rules of the 
Financial Conduct Authority in the United Kingdom.

The Committee assesses the Company’s risk management systems and internal controls on an 
ongoing basis. As part of this, the Group internal auditor attends all meetings. The Committee 
received reports from the external auditors and the Group’s internal auditor on their assessment 
of the control environment. The Committee was provided with updates on the Group’s risk 
management activities and the members considered the risk and control implications on an 
ongoing basis. Additionally, the Board received presentations and reports by management on 
operational and financial performance each quarter that allowed for assessment of risk and 
internal controls.

The Committee meetings during the year included presentations by EY regarding planning and 
outcomes of the annual audits and interim review. 

The Committee reviewed matters reported to the external whistleblowing hotline and reports on 
the findings of the investigations. There were no matters reported which were considered 
significant. Following findings and recommendations by the Group’s internal auditor, the 
Anti-Bribery and Corruption Policy was updated, which the Committee considered and approved. 
There were no bribery matters reported during the year.

All incidences of fraud and irregularities together with any reports on investigations were 
reviewed and the Committee monitored the implementation of corrective controls where 
appropriate. 

To give consideration to 
relevant laws and regulations, 
the provisions of the Code and 
the requirements of the UK 
Listing Rules

The Committee received adequate timely information from EY relating to significant audit, 
accounting and governance developments during the year. The Company Secretary provided 
assurance with regard to compliance with the London Stock Exchange, the UK Listing Authority 
and other regulatory requirements in the preparation of the Annual Report and Regulatory News 
Services announcements.

Audit Committee continued

Role

Activities in 2016

To monitor and review the 
effectiveness and 
independence of the internal 
audit function

To review the quality and 
effectiveness of the external 
audit and the procedures and 
controls designed to ensure 
auditor independence 

The Group’s internal auditor attends all meetings and reports directly to the Committee. After 
every meeting, the Committee meets with the Group internal auditor independently. Outside of 
meetings, the Chairman met with the Group internal auditor to discuss the strategy behind the 
internal audit function and the results of completed audits. At the end of the previous year the 
Committee considered and approved the internal audit plan that included audits of an 
operational, financial and governance compliance nature across the Group. During the year the 
Committee reviewed findings from these internal audits, the actions taken to implement the 
recommendations made in the reports and the status of progress against previously agreed 
actions. The Committee reviewed and approved the 2017 internal audit plan. 

During the year the Committee considered the performance and audit fees of the external 
auditor, and the level of non-audit work undertaken, and recommended to the Board that a 
resolution for the reappointment of EY for a further year as the Company’s auditor be proposed to 
shareholders at the AGM in June 2016. 

In advance of the 2016 audit, the Committee reviewed and approved the external auditor’s audit 
plan and assessed the appropriateness of the audit strategy, scoping, materiality and audit risks.

The Committee approved the audit fees as part of the audit planning process.

The Committee approved an updated policy on the provision of non-audit services by the 
external auditor having considered the Auditing Practices Board’s Ethical Standards.

The Committee reconsidered the requirement for the rotation of external auditors through a 
tender process. Following its assessment, the Committee has recommended the reappointment 
of EY at the AGM on 6 June 2017.

Details of the Committee’s assessment of the auditor’s independence, its assessment of their 
effectiveness and its audit firm rotation considerations are provided on pages 78 and 79.

Significant issues considered by the Committee relating to the 2016 financial year
The Committee considers the following to be the significant issues in respect of the Group’s financial statements, based upon its 
interaction with management. These areas also represent significant audit risk areas for EY and, accordingly, the Committee was provided 
with detailed reports and conclusions on these areas to ensure there are no inconsistencies or misstatements of the financial statements. 

Revenue recognition

Critical accounting estimates 
and judgements applied to 
the ‘production start date’ of 
the Ghaghoo mine 

The judgement applied to revenue recognition is based on the timing of risks and rewards of 
ownership transfer on rough diamond sales and in particular on the uplift element of rough 
diamonds sold into partnership arrangements. This is an area of higher audit risk and accordingly, 
the Committee received detailed verbal and written reports from EY regarding management’s 
appropriate application of its revenue recognition policy.

The judgement in relation to ‘production start date’ is to determine when a mine moves from its 
construction phase into its production phase. The criteria used to assess the start date are 
determined by the nature of each mine’s construction. Relevant criteria are considered to assess 
when the mine is substantially complete and ready for its intended use and moves into the 
production phase at which point the capitalisation of certain mine construction costs cease and 
depreciation of the mine asset commences. The Committee addressed such issues through 
reports submitted by management. This created a platform for open discussion where 
management communicated the reasoning behind their views to conclude that ‘production start 
date’ had not yet been reached. 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements77

Assessing the Ghaghoo 
development asset for 
impairment 

The judgements in relation to asset impairment largely relate to the assessment of whether 
impairment indicators exist and key assumptions used in determining recoverable amounts. The 
Committee addresses these matters through receiving reports from management outlining the 
basis for the assumptions used, of which the business plan is the most significant, which is 
approved by the Board. 

During the half-year review, the Group recognised an impairment charge of US$40.0 million for 
the Ghaghoo asset which was outside the normal course of business. The Committee carefully 
reviewed this impairment to ensure that the judgements applied by management were 
reasonable and any accounting guidance followed correctly. A special Audit Committee meeting 
was convened to consider this matter and thereafter the matter referred to the Board. The 
Committee and Board agreed that as a result of the continued market uncertainty experienced 
the ongoing difficult market conditions for Ghaghoo’s production, strengthening of the Botswana 
pula against the US dollar and the challenges in the operation reaching its targeted production, 
that the impairment charge be recognised. The Committee also concluded that assumptions and 
judgements taken by management with regard to diamond prices and market recovery in the 
short term were on a basis consistent with market indications.

During the second half of 2016, the market for the Ghaghoo production saw an even further 
decline and the Board concluded to place the mine on care and maintenance in 2017. Following 
the same approach as the half-year, the Committee and Board agreed with management’s 
recommendation to realise a further impairment of the Ghaghoo assets, and a further 
US$130.8 million impairment charge was recognised, resulting in a total impairment charge of 
US$170.8 million for the year. 

ANNUAL REVIEW 
The Committee’s performance is reviewed through the broader 
Board evaluation process and, at least annually, the Committee 
reviews its own Terms of Reference to ensure it is operating at 
maximum effectiveness and recommends any changes it 
considers necessary to the Board for approval.

Overall, the Board evaluation performed during the year 
concluded that the Committee is responding appropriately to its 
Terms of Reference. Priorities for the forthcoming year will include 
continuing to monitor the effectiveness of risk management 
processes and internal controls and to further review the quality 
and effectiveness of the external audit and the procedures and 
controls to ensure auditor independence. 

RISK MANAGEMENT AND INTERNAL CONTROLS 
Risk management 
The Committee continued to consider the process for managing 
risk within the business and assisted the Board in relation to 
compliance with the Code and development of the risk appetite 
framework. 

The Committee reviewed, and considered appropriate, the 
updated Group Enterprise Risk Management Policy which forms 
the basis of developing the strategic risks of the Group once all 
operational risks are assessed. The Committee also considered 
management’s response to strategic risk, including the level of 
assurance provided around the risk and how the risk is tracked 
using key risk indicators.

The Committee also receives management reports satisfying the 
adequacy of asset and liability insurance cover across the Group 
and in addition, during the year, satisfied itself with the adequacy 
of the level of Director and Officer’s liability insurance, when 
compared to market practice, through a presentation by the 
Company’s insurance brokers. 

Further information on the strategic risks and uncertainties and 
risk management process is included within the Strategic Report 
on pages 2 to 59.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements78

Audit Committee continued

Internal controls 
The Board has overall responsibility for the Group’s systems of 
internal control and for regularly reviewing the effectiveness of 
those systems. The Committee assists the Board in reviewing the 
systems of internal control. The primary responsibility for the 
operation of these systems is delegated to management. Such 
systems can only provide reasonable and not absolute assurance 
against material misstatement or loss. Key control procedures are 
designed to manage rather than eliminate risk. 

The Committee regularly reviews the adequacy and effectiveness 
of the Group’s internal control procedures through regular reports 
from the Group’s internal auditor and chief financial officer, and 
through consideration of the external auditor’s audit reports and 
face to face discussion between the Audit Partner, the Committee 
Chairman and Committee members.

For 2016, the Committee remained satisfied that no material 
weaknesses in internal control systems were identified. Whilst 
being satisfied that controls and risk management remain 
appropriate for the Group’s activities, the Committee continues to 
undertake a thorough review and to challenge internal controls, 
risk management procedures and internal audit strategy to 
ensure that its practices develop and remain appropriate. When 
internal control reviews identified necessary or beneficial 
improvements, appropriate steps have been taken to ensure the 
control environment is effective. This includes systems to track 
management’s responses to the areas for improvement and 
follow-up internal audits to test the implementation. 

Whistleblowing 
The Group has arrangements in place that enable employees to 
raise concerns in confidence about any possible risks to 
employees or the Company. The Committee considers the 
process and procedures each year and is of the view that they are 
operating appropriately and that colleagues are aware of and 
trust the process. 

OUR AUDITORS 
Internal 
In 2014, the Group established an internal audit function, staffed 
by a Group internal auditor who reports directly to the 
Committee. On approval of the internal audit plan for the year, 
the Committee reviews findings from internal audit reports, the 
actions taken to implement the recommendations made in 
the reports and the status of progress against previously agreed 
actions. All internal audit reports are available to the Committee. 

At the end of every Committee meeting, the Committee meets 
with the internal auditor independently to obtain assurance that 
management is adequately addressing the internal audit report 
findings. 

External auditor 
Engagement 
The Committee is responsible for agreeing the terms of the 
engagement letter. Throughout the year, the Committee received 
reports from EY on its plans, progress and results of its review and 
audit. The Committee considers carefully the scope of planned 
work and the assessment of risk and materiality on which it is 
based. The Committee reviews the negotiated audit fee 
arrangements to ensure that there is an appropriate balance 
between the scope of work and the cost of assurance. The 
Committee’s aim is to support a robust and effective audit and 
strong reporting lines to the Committee.

Effectiveness and quality 
Audit quality is reviewed throughout the year and in 2016 the 
Committee considered the effectiveness, objectivity, skills, 
capacity and independence of EY. In forming its assessment of the 
effectiveness of the audit, prior to the audit, the Committee 
received formal planning documentation from EY regarding the 
proposed audit strategy and the Chairman met separately with 
the Audit Partner to discuss the audit strategy in detail. These 
forums enabled the Committee to assess the extent to which the 
audit strategy was appropriate for the Group’s activities and 
addressed the risks the business faces. In addition, the following 
factors were discussed:
 u independence;
 u materiality;
 u the auditor’s risk assessment;
 u the extent of the Group auditors’ participation in the subsidiary 

component audits;

 u the limited audit firms representation in Lesotho and 

Botswana;

 u the planned audit procedures to mitigate risks; and 
 u regulatory updates affecting the Company.

Following the audit, EY presented its findings to the Committee 
and met separately with the Committee Chairman to discuss key 
audit judgements and estimates and its report. This provided an 
opportunity to assess the audit work performed, understand how 
management’s assessments had been challenged and assess the 
quality of conclusions drawn. The Committee also made enquiries 
of Senior Management to obtain their feedback on the audit 
process and considered this feedback in its assessment.

Each of the key attributes for audit effectiveness was considered 
to be appropriately met by the Group’s auditors and the 
Committee considers the external audit to be robust and 
effective. 

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements79

Reappointment 
EY has been the Group’s external auditors for 10 years since the 
year ended 31 December 2006. The Company recognises the 
importance of audit independence and the requirements of audit 
rotation through tender. A full assessment was carried out during 
the year in relation to the tender of audit firms, the results of 
which identified that the requirement to rotate auditors every 10 
years is a requirement of the EU Audit Regulation and Directive. 
As the Company is not subject to this Directive, as it is not a UK 
registered entity, it was concluded that it is not obliged to rotate 
its auditors. The Committee was satisfied that based on the audit 
effectiveness and quality assessment conducted, and the 
independence following the Audit Partner rotation, the audit 
would not be put on tender at this stage and that the Group will 
continue with EY. 

Resolutions allowing the Board to reappoint and determine the 
external auditor’s remuneration will therefore be proposed at the 
Company’s AGM on Tuesday, 6 June 2017.

Independence, objectivity and fees 
The Committee seeks to ensure the objectivity and independence 
of the auditor through: 
 u focus on the assignment and rotation of key personnel; 
 u the adequacy of audit resource; and 
 u policies in relation to non-audit work. 

The Senior Audit Partner serves no more than five years 
continuously and the independent review partner serves no more 
than seven years continuously. Other key partners serve for no 
longer than seven consecutive years. The Committee monitors 
the tenure of partners and senior staff as well as former 
employees working for the Company. Following completion of 
the 2015 audit, the Audit Partner, Mirco Bardella, rotated off the 
engagement and was replaced by Steven Dobson, a Senior 
Partner, which was approved by the Committee. 

The Committee regularly monitors the other services being 
provided to the Group by its external auditor, and has approved a 
formal policy and sign-off process with management to ensure 
this does not impair their independence or objectivity. The policy 
was reviewed and updated during the year. 

Other than in exceptional circumstances, management and the 
Committee do not expect non-audit fees to be in excess of fees 
for audit and audit-related services. The fees for such work 
amounted to US$0.2 million in total. This was against external 
audit fees of US$0.7 million representing approximately 29% of 
external audit fees. The significant non-audit engagements relate 
mainly to the half-yearly interim review and to a lesser extent 
corporate tax services. Full details are set out in Note 3 of the 
financial statements. A report on the level of non-audit work 
provided by the auditor is given to the Committee half-yearly. 

The Committee has formally reviewed the work undertaken by EY 
throughout the Group and is satisfied that the advice it has 
received has been objective and independent.

The Committee comprises:

 u RW Davis – Chairman
 u M Salamon
 u CT Elphick 

COMPOSITION AND MEETINGS 
The Nominations Committee comprises two non-Executive 
Directors and one Executive Director. The Committee’s Terms of 
Reference provide for a formal and transparent procedure for the 
Committee to follow in executing its responsibilities. The Terms of 
Reference of the Nominations Committee were updated in 
September of 2015 to reflect the changes made to the Code in 
September 2014, and to further reflect current best practice. They 
were again reviewed in March 2017 to ensure they continued to 
be in line with good governance. 

ROLE AND ACTIVITIES 

Role

Activities in 2016

Four meetings were held in 2016 with succession planning being the 
key focus for the Committee in 2016. Alan Ashworth retired as Chief 
Operating Officer and was replaced by Johnny Velloza who was 
considered a suitable candidate based on his operational experience 
and reputation within the industry. As reported at the 2016 AGM, the 
Chairman of the Board, Roger Davis, will be stepping down at the 
2017 AGM as he has served a ten-year tenure. Gavin Beevers, a 
non-Executive Director, has also served a ten-year tenure on the Board 
and the Committee has been looking for suitable candidates to 
replace him. The Committee carried out an extensive search and 
interviewed a range of potential candidates with mining and technical 
experience. Due to the specific knowledge and experience required, it 
has proved difficult to find a suitable candidate that fulfils the Group’s 
requirements. Mr Beevers has agreed to remain in post (subject to 
re-election at the AGM). Mr Beevers has considerable technical skills 
and knowledge in operational mining and corporate social 
responsibility. His diligence, dedicated commitment and expertise are 
invaluable on site visits.

In the year ahead, the Committee will continue to assess the 
Board’s composition, evaluate the composition of the various 
Committees and monitor developments in corporate governance 
to ensure the Group remains at the forefront of good 
governance practices.

To review the structure, size and 
composition of the Board 
(including appropriate skills, 
knowledge, experience and 
diversity), and to make 
recommendations to the Board 
with regard to any changes that 
are deemed necessary

To satisfy itself, with regard to 
succession planning, that plans 
are in place with regard to both 
Board and Senior Management 
positions

With the retirement from the Company and the Board of Mr Ashworth, the Chief Operating 
Officer, in June 2016, the Committee reviewed the structure and size of the Board and it was 
agreed that the Company had the optimum balance of skills and independence on the Board 
and therefore the appointment of the Chief Operating Officer would be best served as a 
non-Board position. The Chief Operating Officer is invited to attend all Board meetings.

Short and long-term succession planning was a key focus for the Committee during the year. For 
the short term, an emergency succession plan was approved to ensure that suitably qualified 
and experienced executives and senior members of the management team would step in to fill 
vacancies arising from unforeseen circumstances and thereby provide business continuity. 

For the long term, the Committee considered suitable replacements for Mr Davis, the Chairman 
of the Board, as well as for Mr Beevers who has reached his 10-year tenure as a non-Executive 
Director. The Committee carried out an extensive search and interviewed a range of potential 
candidates with the appropriate skills, knowledge and experience to ensure any suitable 
replacement not only had the requisite skills and experience but also whose attributes 
complemented the current Board composition and structure.

Role

Activities in 2016

To identify, nominate and 
recommend, for the approval of 
the Board, appropriate candidates 
to fill Board and Committee 
vacancies as and when they arise

To recommend to the Board the 
re-election by shareholders at the 
AGM of any Director under the 
retirement and re-election 
provisions of the Company’s 
by-laws

To ensure all new Directors 
undertake appropriate training 
and induction to ensure that they 
are fully informed about strategic 
and commercial issues affecting 
the Company and the markets in 
which it operates as well as their 
duties and responsibilities as a 
Director

To keep under review potential 
conflicts of interests of Directors 
disclosed to the Company and 
develop appropriate processes 
for managing such conflicts if 
considered necessary

To assist the Chairman of the 
Board with the implementation 
of an annual evaluation process 
to assess the overall and 
individual performance and 
effectiveness of the Board and its 
Committees

The Committee considered that the reduced size of the Board following the retirement of 
Mr Ashworth was appropriate and agreed that the appointment of Mr Velloza as the Chief 
Operating Officer would be a non-Board position. 

The Committee confirmed the stepping down of Mr Davis and Mr Beevers at the 2017 AGM. The 
Committee subsequently considered and approved that, subject to re-election at the 2017 AGM, 
Mr Beevers remain in post. 

The Committee recommended all other Directors for re-election to the Board at the forthcoming 
AGM.

Mr Lynch-Bell‘s induction was completed during the year with the assistance of the Company 
Secretarial team. In addition, he visited the financial and internal audit teams in Johannesburg 
during the year and again in February 2017, together with a site visit to the Letšeng mining 
operation in Lesotho.

The Committee was satisfied with the process of disclosure of conflicts of interest and no 
instances of such conflicts arose during the year. The Directors are required to inform the Board 
of any potential or possible conflicts immediately and prior to Board meetings. The Register of 
Conflicts is circulated and approved each year and as and when any changes are reported.

A questionnaire-based board evaluation was conducted by an external adviser to assess the 
performance and effectiveness of the Board and the Committees. The Committee reviewed the 
results to ascertain if there were any issues that may require addressing. A full summary of the 
evaluation process can be found on pages 69 and 70.

EXPERIENCE AND SKILLS OF THE DIRECTORS
The Committee is satisfied that the Directors add the relevant 
skills to the Board that is required for the Company to succeed in 
achieving its strategy of growth, value creation and sustainability 
through diamond mining. All the Directors worked in the mining 
and/or financial and capital market sector prior to joining the 
Group and their key skills and experience can be found in the 
directorate section, pages 62 and 63. 

DIVERSITY
The Board acknowledges that diversity extends beyond the 
boardroom and supports management in its efforts to build 
diversity throughout the Group. It endorses the Group’s policy to 

attract and develop a highly qualified and diverse workforce, to 
ensure that all appointments are based on merit and recruitment 
activities are fair, non-discriminatory and that due diligence is 
performed. The Committee recognises that to further enhance 
the effectiveness of the Board there must be combined qualities, 
capabilities and skill set gained from different geographical and 
cultural backgrounds. It is also recognised that there is a shortage 
of suitable appropriate Directors currently in the market. The 
Nominations Committee continues to encourage and support 
diversity of business skills and experience. Details including the 
proportion of women in Senior Management, can be found in the 
Sustainable Development Review on pages 55 and 56.

HSSE Committee

Gavin Beevers, Chairman

The Committee comprises:

 u GA Beevers – Chairman
 u M Salamon
 u GE Turner 

COMPOSITION, EXPERIENCE, AND SKILL SET
The Committee members have a wealth of knowledge which 
supports the objectives of ensuring HSSE risks are mitigated and 
best practice is attained. Gavin Beevers, the Chairman of the 
Committee, and Mike Salamon have extensive experience in 
operational mining which not only enables a great understanding of 
current challenges within the industry, but provide the tools and 
expertise to overcome these challenges and to lead best practice. 
Glenn Turner, with his legal expertise has extensive knowledge of 
local and international law, enabling the Company to have the 
relevant policies and agreements in place in respect of HSSE. 

TERMS OF REFERENCE 
The Terms of Reference for the HSSE Committee are reviewed 
annually at the March Committee meeting to ensure the terms 
guiding the Committee are relevant, fit for purpose and generate 
open discussion in line with best practice. The Committee Terms of 
Reference are available to view on the Company website. 

MEETINGS
Four meetings of the HSSE Committee were held in 2016. The 
Chief Operating Officer and the Group’s HSSE Superintendent 
attend and present at the meetings upon invitation.

ROLE AND ACTIVITIES 
The Chairman of the HSSE Committee visited the Group’s operations 
to obtain first-hand knowledge of current practices. The HSSE 
management teams at the Group’s operations continually assist the 
Committee to ensure policies and procedures remain current, 
effective and in line with industry practice.

ROLE AND ACTIVITIES 

Role

Activities in 2016

To evaluate the effectiveness of 
the Group’s policies and systems 
in identifying and managing HSSE 
risks as well as ensuring 
compliance with applicable legal 
and regulatory requirements 

To assess the impact of HSSE 
decisions and actions on the 
Group’s employees, project-
affected communities (PACs) and 
other stakeholders as well as the 
reputation of the Group

The Committee evaluated the effectiveness of the Group’s HSSE management policies and 
reviewed reports on HSSE performance on a quarterly basis. The Committee reviewed legal and 
regulatory compliance of the Group’s mining operations by considering the results of legal 
compliance audits which were presented at the Committee meetings. In addition to the legal 
compliance audits, the Chairman and Committee members requested quarterly updates on the 
management of critical HSSE features. These critical features were identified by the Committee 
following discussions ahead of and/or during Committee meetings and took into consideration 
activities within the Group as well as the global mining environment. Some of the critical 
features monitored by the Committee during 2016 included:
 u radiation management at Letšeng;
 u tailings and water storage facility management at Letšeng and Ghaghoo; and
 u water management, more specifically at Ghaghoo. 

The Committee considers reports on any significant or major HSSE incidents during meetings. There 
were no significant or major environmental or social incidents recorded, five significant safety 
incidents were reported. The Committee assesses the impact of HSSE decisions on the Group’s 
reputation on an ongoing basis, with specific attention being given to the Group’s social licence to 
operate. HSSE decisions and/or actions that have the potential to impact the Group’s relationship 
with its stakeholders, or its reputation are proactively identified by the Committee and monitored 
during or outside the Committee meetings, depending on the potential severity of the impact. 
Social upliftment projects are closely monitored by the Committee to ensure the correct process is 
followed and stakeholder relationships are safeguarded.

Role

Activities in 2016

To review reports from 
management concerning all 
fatalities and serious accidents 
within the Group and actions 
taken by management because 
of such serious accidents

No fatalities occurred during the year, but the Committee received reports on all five of the 
serious accidents that occurred in the Group. The Committee reviewed incident investigation 
reports on the lost time injuries and found the reports to adequately identify the root causes of 
the incidents and recommend appropriate corrective actions. The Committee received reports 
on the implementation of corrective actions as well as health and safety system reviews to 
mitigate against the reoccurrence of such accidents in future. 

To evaluate and oversee the 
quality and integrity of any 
reporting to external stakeholders 
concerning HSSE issues and 
review the Group’s HSSE 
performance indicators

To review the results of 
independent audits of the Group’s 
performance in respect of HSSE 
matters

To review any strategies and 
action plans developed by 
management in response to 
issues raised in terms of HSSE and 
where appropriate, make 
recommendations to the Board

The Committee evaluates HSSE data presented in reports on a quarterly basis and has, on occasion, 
requested further review of data to ensure accuracy throughout the reporting process. In addition to 
the HSSE issues reported on in the half-year reports, the Committee also reviews the Annual 
Sustainable Development Report, which details the Group’s HSSE performance throughout the year.

The Committee reviewed the Group’s HSSE performance indicators and trends for both current 
and forward looking periods to ensure relevance and appropriateness. The performance 
indicators are heavily influenced by the Group’s past performance as well as the Global 
Reporting Initiative’s Sustainability Guidelines. 

During the year the Committee considered external audit reports regarding the mining 
operations’ performance in respect of HSSE systems, management as well as legal compliance. 
The Committee received feedback with regard to the following independent audits:
 u HSE systems and management at Ghaghoo;
 u HSSE legal compliance at Ghaghoo;
 u social and environmental management plan (SEMP) compliance at Ghaghoo;
 u ISO 14001 environmental management system at Letšeng;
 u ISO 18001 occupational health and safety management at Letšeng;
 u HSSE legal compliance at Letšeng; and
 u SEMP compliance at Letšeng. 

The Committee monitored the close out of HSSE-related findings resulting from these 
independent audits through quarterly status reports.

The Committee assessed the appropriateness of HSSE action plans and strategies developed by 
operational management to address HSSE matters and reviewed the effectiveness of these 
strategies in addressing HSSE trends or shortfalls. During the year the Committee monitored, 
among others, the following action plans and strategies:
 u nitrate management action plan at Letšeng;
 u surface water management strategy at Ghaghoo;
 u behaviour-based care at Letšeng; and
 u rockfall safety awareness campaign at Ghaghoo. 

The Committee also recommended further actions to the Board where appropriate.

Annual Statement on Directors’ remuneration

Malus and clawback provisions
The Committee notes the requirement for malus and clawback 
provisions in incentives in the UK Corporate Governance Code, 
and the increasing prevalence of these provisions in FTSE 
incentive plans. The Company is therefore introducing malus and 
clawback provisions from 1 January 2017 in respect of the annual 
bonus, and from awards due to be made in March 2017 in respect 
of the Employee Share Option Plan (ESOP).

Share ownership and retention guidelines
The Company will be introducing shareholding guidelines from 
1 January 2017 in order to encourage Executive Directors to 
acquire and maintain a level of ownership of shares that more 
closely aligns their interests with those of the Company’s other 
shareholders. The guideline is for Executive Directors to hold 
100% of salary in beneficially owned shares. Until the guideline 
has been met, Executive Directors will be required to retain 50% 
of vested awards under the ESOP or any other share-based 
incentive.

REMUNERATION DECISIONS IN 2016
Letšeng met its operational performance targets notwithstanding 
the effect of inclement weather. The lack of large value diamonds 
recovered during the year, coupled with weak diamond prices 
amid continued poor market conditions, contributed to 
disappointing results in 2016.

In this context, the Committee’s key decisions during the year 
related to the following areas:

Annual bonus
For 2016 the formulaic annual bonus outcome for the business 
scorecard was 35%. However, in the context of challenging 
operating conditions and the Group’s performance in 2016, the 
Executive Directors and the Remuneration Committee jointly 
agreed that no bonus should be paid to the Executive Directors 
for 2016.

ESOP
Based on performance to 31 December 2016, 28.26% of the share 
awards made under the 2014 ESOP will vest in June 2017. In 
respect of the relative Total Shareholder Return (TSR) element 
(25% of the award), performance is measured versus the 
constituents of the FTSE 350 Mining Index; 0% vested. In respect 
of the production element (37.5% of the award), 7.18% will vest 
and for the profit element (37.5% of the award), 21.08% will vest.

Dear Shareholder
On behalf of the Board I am pleased to present the Remuneration 
Committee’s Directors’ Remuneration Report for 2016.

PROPOSED 2017 REMUNERATION POLICY
In line with last year, this report is split into three sections: the 
Annual Statement, the Directors’ Remuneration Policy and the 
Annual Report on Remuneration. 

During 2016, the Remuneration Committee reviewed the 
appropriateness and effectiveness of the existing Remuneration 
Policy, which was approved by shareholders at the 2014 Annual 
General Meeting (AGM). The Committee believes that, on the 
whole, the policy has served the Company well to motivate and 
reward Senior Executives, and align their interests with those of 
the Company and our shareholders. This year we will be asking 
our shareholders to approve a new Remuneration Policy for 
Executive Directors at the 2017 AGM. The proposed 2017 policy 
remains broadly unchanged from the 2014 policy. However, the 
Committee is aware of a small number of areas where the 2014 
policy was not fully in line with current general shareholder 
preferences, and we are therefore taking this opportunity to 
introduce a number of best practice changes in the proposed 
2017 policy as follows.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements 
85

In March 2016, Executive Directors were granted awards under 
the ESOP which will vest based on performance over the three 
financial years to 31 December 2018. In line with the prior year, 
these awards will vest to the extent that challenging relative TSR, 
production and profit targets are achieved over the period.

IMPLEMENTATION OF THE REMUNERATION POLICY 
IN 2017
The Executive Directors’ salaries were reviewed in March 2017, and 
in light of the current environment no increases were awarded.

For 2017, the annual bonus opportunity will remain 100% of 
salary. Performance will continue to be measured with reference 
to a business scorecard linked to growth, operating performance 
and HSSE performance (weighted 80% of maximum), and to 
personal performance (20% of maximum). Malus and clawback 
provisions will apply for a period of two years following payment.

Executive Directors were granted awards under the ESOP in 
March 2017, subject to the shareholders’ approval of the 
Remuneration Policy in June 2017, of between 55% and 62% of 
salary. Awards will vest on performance over the three financial 
years to 31 December 2019. The performance conditions remain 
25% on relative TSR versus the FTSE 350 Mining Index, 37.5% on 
production and 37.5% on profit. Malus and clawback provisions 
will apply during the vesting period and for a period of two years 
following vesting.

Further details on the implementation of the policy for 2017 are 
included on pages 86 to 93.

DIRECTORATE CHANGE
AR Ashworth retired from the Board and ceased to be employed 
on 30 June 2016. All payments made to AR Ashworth are in line 
with default treatment under the Company’s existing 
Remuneration Policy for a good leaver, as approved by 
shareholders at the 2014 AGM, and consistent with his service 
agreement and his statutory employment rights. Further details 
on exit payments made to AR Ashworth are included on page 99.

Resolutions to approve the proposed Remuneration Policy 
(subject to a binding vote) and the Annual Report on 
Remuneration (subject to an advisory vote) will be put to our 
shareholders at the forthcoming AGM. We continue to value 
feedback from our shareholders and hope to receive your support 
at the AGM.

Directors’ Remuneration Policy

The Company’s Remuneration Policy is designed to provide a level of 
remuneration which attracts, retains and motivates executives of a suitable 
calibre to carry out the Company’s business strategy and maximise long-term 
shareholder wealth.

The report has been prepared in accordance with the principles 
of the Companies Act 2006 and Schedule 8 of The Large and 
Medium-sized Companies and Groups (Accounts and Reports) 
(Amendment) Regulations 2013. The Regulations require our 
auditors to report to shareholders on the audited information 
within this report and to state whether, in their opinion, the 
relevant sections have been prepared in accordance with the Act. 
The auditors’ opinion is set out on pages 113 to 119 and we have 
clearly marked the audited sections of the report.

As required by legislation, the Remuneration Policy as set out in 
this section of the report will be put to a binding shareholder vote 
and, subject to shareholder approval, will become effective from 
the date of the 2017 AGM. The proposed policy is broadly 
consistent with the approved 2014 policy, save the changes 
highlighted in the Remuneration Committee Chairman’s 
Statement.

is intended that, as far as possible, remuneration policies and 
practices will conform to best practice in the markets in which the 
Company operates and will be aligned with shareholder interests 
and promote effective management of business risk.

The Committee takes into account the UK Listing Rules, the 
principles and provisions of the Code and the guidance provided 
by institutional investor representative bodies in determining 
executive remuneration arrangements. In deciding on the 
appropriate structure and quantum of remuneration, the 
Committee reviews remuneration practices at comparator 
companies, comprising mining companies and UK-listed 
companies of a similar size and complexity, to ensure 
remuneration policies reflect, as appropriate, prevailing industry 
and market conditions. Furthermore, remuneration policies have 
taken, and will continue to take, account of pay and employment 
conditions elsewhere in the Group.

THE COMPANY’S REMUNERATION POLICY
The Company’s Remuneration Policy is designed to provide a 
level of remuneration which attracts, retains and motivates 
executives of a suitable calibre to carry out the Company’s 
business strategy and maximise long-term shareholder wealth. It 

The Committee’s policy is to weight remuneration towards 
variable pay. The aim is to provide base salaries and benefits that 
are fair, and variable pay incentives linked to the achievement of 
realistic performance targets relative to the Company’s strategy 
and corporate objectives.

Directors’ Remuneration Policy continued

NOTES TO POLICY TABLE
Payments from existing arrangements 
Executive Directors will be eligible to receive remuneration or 
other payments in respect of any award granted or payment 
agreed prior to the approval and implementation of the 2017 
policy, or prior to the individual becoming a Director. Details of 
any such awards or payments are disclosed in the Annual Report 
on Remuneration.

Selection of performance measures (annual bonus and 
ESOP)
The performance measures used in the Company’s executive 
incentive scheme have been selected to ensure incentives 
reinforce the Company strategy and align executive interests 
closely with those of shareholders. The Committee considers that 
the financial and operational measures used in the annual bonus, 
support the strategic objectives of value creation, growth and 
sustainability, and are well-accepted measures for the mining 
sector. The use of profit and production is consistent with the 
Company’s KPIs, and the use of relative TSR is strongly aligned 
with shareholders and ensures that executives are rewarded only 
if they exceed the returns which a shareholder could achieve 
elsewhere in the sector.

Performance targets are set to be stretching and achievable, 
taking into account the Company’s strategic priorities and the 
economic environment in which the Company operates. Targets 
are set taking into account a range of reference points including 
the Group’s business plan. The Committee believes that the 
performance targets set are adequately stretching and that the 
maximum outcomes are achievable only for exceptional 
performance.

Remuneration policy for other employees 
The approach to salary reviews is consistent across the Group, 
with consideration given to the level of responsibility, experience, 
individual performance, market levels and the Company’s ability 
to pay.

Below Board level, Senior Management employees participate in 
an annual bonus scheme on a similar basis as the Executive 
Directors, although the weighting on Group performance 
measures increases with seniority. A number of management 
level employees also receive ESOP awards. Performance 
conditions and award sizes vary to be appropriate to the 
organisational level. 

Shareholding guidelines
The guideline for Executive Directors is that they hold 100% of 
salary in beneficially owned shares. Until the guideline has been 
met, Executive Directors will be required to retain 50% of vested 
awards under the ESOP or any other share-based incentive.

Pay for performance: scenario analysis 
The following graphs provide an estimate of the potential future 
remuneration for the Executive Directors and the potential split 
between the different elements of pay under three performance 
scenarios: ‘fixed’, ‘at target’ and ‘maximum’. Potential remuneration 
is based on incentive opportunities as set out in the proposed 
2017 policy, applied to the salaries effective 1 April 2017. For the 
annual bonus, the maximum is 100% of salary. ESOP values are 
based on the proposed number of shares to be awarded in 2017 
and the three-month average share price to 31 December 2016 
of 112 pence (equivalent to 55% to 62% of salary). Note that the 
projected values exclude the impact of any share price 
movements.

The ‘fixed’ scenario includes base salary, pension and benefits 
only.

The ‘at target’ scenario includes fixed remuneration as above, plus 
target payout of annual bonus, and threshold vesting for the 
ESOP.

The ‘maximum’ scenario includes fixed remuneration, plus full 
payout and vesting of all incentives.

The assumptions are summarised in the table below.

Approach to remuneration on executive recruitment
In recruiting new Executive Directors, the Committee will follow 
the Remuneration Policy as set out in the policy table. On 
appointment of an external Executive Director, any arrangement 
specifically established to recruit an individual would be capped 
at the limits described in the policy table. The Committee does 
not envisage a payment such as a ‘golden hello’ would be offered, 
although the Committee may consider it appropriate to 
compensate for incentive arrangements the Director forfeits on 
leaving their current employer. Any such buy-out compensation 
would be on a comparable basis taking into account factors 
including the performance conditions attached to these awards, 
the likelihood of conditions being met, and the remaining vesting 
period of these awards. The Committee would normally use the 
remuneration components under the regular policy to make such 
buy-out awards, but may also exercise its discretion under Listing 
Rule 9.4.2 if an alternative incentive structure were required.

In the case of internal promotions, any commitments made prior 
to promotion and the approval of the Remuneration Policy will be 
honoured. Where the new appointee has an initial salary set 
below market, any shortfall will be managed with phased 
increases over a period of several years, subject to the individual’s 
performance and development in the role.

SERVICE CONTRACTS
The Company’s policy is to limit termination payments on 
termination to pre-established contractual arrangements. In the 
event that the employment of an Executive Director is terminated, 
any compensation payable will be determined in accordance 
with the terms of the service contract between the Company and 
the employee, as well as the rules of any incentive plans. Details of 
the Executive Directors’ service contracts are summarised in the 
table below.

Directors’ Remuneration Policy continued

Payments for loss of office under all service contracts
If an Executive Director’s contract is terminated, payments equal 
to salary in lieu of notice can be made monthly during the notice 
period. Benefits are payable only at the Committee’s discretion. 
Payment in lieu of unused annual leave entitlement can be made 
at the effective salary rate at the point of termination.

If employment is terminated by the Company, the departing 
Executive Director may have a legal entitlement (under statute or 
otherwise) to additional amounts, which would need to be met. 
Where the Company wishes to enter into a settlement agreement 
and the individual must seek independent legal advice, the 
Committee retains discretion to settle any claims by or on behalf 
of the Executive Director in return for making an appropriate 

payment and contributing to the legal fees incurred by 
the Executive Director in connection with the termination 
of employment.

In exceptional circumstances, the Committee may approve new 
contractual arrangements with departing Executive Directors 
including (but not limited to) settlement, confidentiality, 
outplacement services, restrictive covenants and/or consultancy 
arrangements. These will be used only in circumstances where 
the Committee believes that it is in the best interests of the 
Company and its shareholders to do so.

leaver scenarios.

Non-Executive Directors
Non-Executive Directors do not receive benefits from the Company and they are not eligible to participate in any bonus or share incentive 
scheme.

Details of the policy on non-Executive Director fees are set out in the table below. 

Element

Purpose and link to strategy

Operation

DIRECTORS’ FEES

 u To attract and retain a 

high-calibre Chairman and 
non-Executive Directors with 
experience relevant to the 
Company.

 u Fees are reviewed annually, 
with any changes effective 
from 1 April. 

 u Fees are typically set after 

considering current market 
levels and taking into account 
time commitment and 
responsibilities involved.
 u All non-Executive Directors, 
including the Chairman, are 
each paid an all-inclusive fee. 
No additional fees are paid for 
chairmanship of Committees.
 u All fees are payable in cash in 

arrears.

 u The non-Executive Directors 
do not participate in any of 
the Group’s incentive plans. 
No other benefits or 
remuneration are provided to 
non-Executive Directors.

 u No prescribed maximum 

annual increase.

 u It is expected that fee 

increases will typically be in 
line with market levels of fee 
inflation.

 u In certain circumstances (for 
example where there is a 
change in time commitment 
required or a material 
misalignment with market), 
the Committee has the 
discretion to make 
adjustments to fee levels to 
ensure they remain 
competitive. 

 u The maximum aggregate 
annual fee for all non-
Executive Directors, including 
the Chairman, allowed by the 
Company’s Articles of 
Association is £750 000.

Non-Executive Directors do not have service contracts. Summary details of terms and notice periods for non-Executive Directors are

CONSIDERATIONS OF CONDITIONS ELSEWHERE IN 
THE GROUP
The Committee considers the remuneration and employment 
conditions elsewhere in the Group when determining 
remuneration for Executive Directors. Although the Committee 
does not currently consult specifically with employees on the 
executive Remuneration Policy, it receives regular updates from 
the Chief Financial Officer on the pay conditions for employees 
across the Group, and takes these into account when determining 
Executive Director remuneration.

CONSIDERATIONS OF SHAREHOLDER VIEWS
When determining remuneration, the Committee considers 
shareholder views and the guidelines of investor bodies. The 
Committee always welcomes feedback from shareholders on the 
Company’s Remuneration Policy and commits to undergoing 
shareholder consultation in advance of any significant changes to 
policy. Details on the votes received on the Directors’ 

Remuneration Report at the prior AGM is provided in the Annual 
Report on Remuneration.

EXTERNAL DIRECTORSHIPS
Executive Directors are permitted to accept external directorships 
with prior approval of the Chairman. Approval will only be given 
where the appointment does not present a conflict of interest 
with the Group’s activities and the experience gained will be 
beneficial to the development of the individual. Where fees are 
payable in respect of such appointments, these would be 
retained by the Executive Director. Refer to page 104 for further 
details.

RW Davis served three terms as a member of the Remuneration 
Committee, which was the maximum length of time as set out in 
the Committee’s terms of reference. His reappointment for a 
fourth term was approved by the Board.

The Chief Executive Officer and the Chief Financial Officer attend 
Committee meetings by invitation and assist the Committee in its 
deliberations except when issues relating to their own 
remuneration are discussed. Representatives of Kepler, a brand of 
Mercer, also attend the meetings by invitation.

The Committee is a formal Committee of the Board. Its terms of 
reference are available on the Company’s website and comply 
with the UK Corporate Governance Code. 

The Committee’s main responsibilities are to:
 u consider and agree on the Company’s Remuneration Policy for 

approval by shareholders at the AGM;

 u determine individual remuneration packages for the Chairman, 

the Executive Directors and the Company Secretary;
 u monitor and recommend the level and structure of 

remuneration for Senior Management;

 u approve the design of performance-related pay schemes 

operated by the Group and approve total annual payments;

 u review the design of all share-based incentive plans and 

approve the awards to be made;

 u determine the basis for calculating bonuses payable to the 

Executive Directors and Senior Management;

 u make recommendations to the Board on the fees offered to 

the non-Executive Directors;

 u consider major changes in employee remuneration in the 

Group; and 

 u select and appoint consultants to advise the Committee.

The Committee’s policy is to encourage an open and transparent 
dialogue with shareholders on remuneration matters and would 
seek to consult with major shareholders prior to implementing 
any significant changes to the Remuneration Policy.

ACTIVITIES OF THE REMUNERATION COMMITTEE  
IN 2016
During the year, activities undertaken by the Committee included:
 u review of incentive plans across the Group (including 
operating unit incentive plans), and review of the 
Remuneration Policy;

 u review and approval of the Directors’ Remuneration Report for 
2015, and preparation of the Directors’ Remuneration Report 
for 2016;

 u review and approval of incentive outcomes for Executive 

Directors for 2015;

 u determination of the Executive Directors’ annual bonus and 

ESOP opportunities and performance targets for 2016;

 u review of recent developments in remuneration market trends 

and best practice;

 u review and approval of the Chairman’s fee; and
 u review and approval of base salaries and total remuneration for 

the Executive Directors and the Company Secretary.

ADVISERS TO THE REMUNERATION COMMITTEE 
Kepler was appointed by the Committee in February 2010, and 
provided independent remuneration advice to the Committee 
and attended Committee meetings during 2016. Kepler provides 
remuneration advice to a large portfolio of clients including many 
in the FTSE 350 and FTSE Small Cap; this gives the Committee 
comfort that the advice provided is appropriate and relevant. 
Kepler is a signatory to, and abides by, the Remuneration 
Consultants Group Code of Conduct. Further details can be found 
at www.remunerationconsultantsgroup.com. 

Neither Kepler nor Kepler’s parent company, Mercer, provides 
non-remuneration services to the Group or is in any other way 
connected to the Group, and Kepler is therefore considered to be 
independent. The fees payable in relation to work for the 
Committee in 2016 were £53 160 (US$72 023) excluding VAT.

5 AR Ashworth retired from the Board on 30 June 2016. The 2016 remuneration reported in the table relates to the period 1 January 2016 to 30 June 2016.

PENSION AND OTHER BENEFITS
No formal pension provision is made by the Company. Instead, 
Executive Directors receive a cash allowance a cash in lieu of 
pension which was equivalent to 14.5% and 13% of base salary for 
the Chief Executive Officer and other Executive Directors, 
respectively. Executive Directors received a cash allowance in lieu of 
other non-cash benefits, the value of which ranged between 5.5% 
and 6% of base salary during 2016.

INCENTIVE OUTCOMES FOR THE FINANCIAL YEAR 
ENDED 31 DECEMBER 2016
Annual bonus in respect of 2016 performance
Executive Directors participate in a discretionary annual bonus 
arrangement designed to focus participants on the following 
business critical factors: (i) growth strategy implementation, (ii) 
funding, (iii) financial and operational performance, (iv) health, 
safety, social, environment, sustainability, image and relationships, 
and (v) sales, marketing and manufacturing, all of which are 
underpinned by specific KPIs and included in the business plan 
approved by the Board. 

In 2016, the maximum bonus opportunity for Executive Directors 
was 100% of base salary, with 80% linked to a business scorecard 
and 20% linked to a discretionary assessment of personal 
performance.

Growth
The growth component of the bonus is assessed at the discretion 
of the Committee. In terms of performance against the Group’s 
growth targets, the Committee considered the progress made in 
the year and the additional capacity generated from the Plant 2 
expansion project completed in 2015. A post-implementation 
review confirmed that the project was successful with a 12% 
capacity increase. The Committee also considered the Executive 
Directors’ efforts in assessing possible strategic activities. The 
anticipated progress at Ghaghoo was constrained due to the 
operational challenges and the current market conditions 
impacting the Ghaghoo type production. The placing of Ghaghoo 
onto care and maintenance was taken into account and restricted 
the score for this component. The Committee has therefore 
concluded that the growth component of the bonus be limited 
to a payout of 8% (relative to the maximum of 30%).

HSSE legal compliance
Letšeng retained its ISO 14001 and ISO 18001 accreditation for 
environmental and occupational health and safety management 
for a second year in a row, while following an NOSA audit, 
Ghaghoo retained its four-star rating. 

Overall business scorecard outcome

35 (out of 100)

Personal performance
Objectives under the personal element of the bonus were linked to 
each Executive Director’s individual areas of responsibility, and 
designed to collectively support the achievement of the Group’s 
strategic targets for the year. Individual targets comprised 
contributions to the Group’s overall performance and the delivery of 
strategic projects and initiatives as set out by the Board, including 
but not limited to: operational performance, strengthening of key 
stakeholder relationships, bank financing and treasury management 
and HSSE objectives.

In light of the decision that no bonuses will be payable to the 
Executive Directors, the personal performance was not assessed 
for purposes of annual bonus calculation.

Actual bonuses awarded for 2016
Based on the business scorecard, the resulting formulaic annual 
bonus outcome for Group performance was 35%. However, in the 
context of the challenging operating conditions and the Group’s 
performance in 2016, the Executive Directors and the 
Remuneration Committee jointly agreed that no bonus should be 
paid to the Executive Directors for 2016.

AR Ashworth retired from the Board and ceased to be employed 
on 30 June 2016. At the start of 2016, it was agreed that he would 
be eligible for a time pro-rated bonus of 50% of annual salary for 
2016. Performance would be linked to a similar mix of business 
(weighted 80% of maximum bonus) and personal (weighted 20% 
of maximum bonus) objectives as for other Executive Directors, 

measured over the period 1 January to 30 June 2016. Based on 
the Group’s published half-year results, actual outcome for the 
business scorecard element was 37% of maximum, equivalent to 
15% of annual salary after pro-rating for time served. The

37 (out of 100)

In respect of performance in the HSSE legal compliance category, 
no major findings were registered for the period 1 January to 
30 June 2016. 

The Committee also assessed AR Ashworth’s personal 
performance during the period, and agreed an outcome of 80% 
of maximum, equivalent to 8% of annual salary pro rata. In 
assessing the personal performance, the Committee took into 
account the strong operational performance at Letšeng and the 

achievement of HSSE objectives with zero fatalities. The 
Committee agreed that AR Ashworth successfully carried out his 
duties in line with the Group’s objectives. The total bonus paid 
was therefore 23% of an annual salary of £346 700, ie £78 892.

Vesting of the awards was dependent on relative TSR versus the 
constituents of the FTSE 350 Mining Index (25% of the award), 
profit (37.5%) and production (37.5%), measured over the 
three-year performance period ended 31 December 2016. 
Relative TSR was measured over the period 1 January 2014 to 

31 December 2016. Profit and production were measured on an 
annual basis with respect to the business plan for the year, with 
final vesting based on the average achievement of targets over 
the three years. The performance conditions that applied to these 
awards are summarised in the table below.

For each measure, for achievement between threshold and 
stretch, and stretch and super-stretch, the award vested on a 
straight-line basis. For achievement of less than threshold, vesting 
was nil.

Based on performance to 31 December 2016, 28.26% of the 
maximum award will vest for CT Elphick, M Michael and GE Turner 

in June 2017, subject to continued employment. AR Ashworth 
retired from the Board and ceased to be employed on 30 June 
2016, and therefore his 2014 ESOP award was reduced on a time 
pro-rata basis to reflect the period served (see page 99 for further 
information on treatment of his outstanding incentives).

For each measure, for achievement in between threshold and 
stretch, and stretch and super-stretch, the award will vest on a 
straight-line basis. For achievement of less than threshold, vesting 
will be nil. As before, TSR will be measured over three years, from 
1 January 2016 to 31 December 2018. Profit and production will 
be measured on an annual basis with respect to the business plan 
for the year, with final vesting based on the average achievement 
of targets over the three years. The profit and production targets 
are considered commercially sensitive as they relate to the 
Company’s business plan and strategy, and will therefore be 
disclosed in full after the performance period has ended.

EXIT PAYMENT
AR Ashworth retired from the Board and ceased to be employed 
on 30 June 2016. All payments made to AR Ashworth are in line 
with default treatment under the Company’s existing 
Remuneration Policy for a good leaver, as approved by 
shareholders at the 2014 AGM, and consistent with his service 
agreement and his statutory employment rights.

AR Ashworth is entitled to 12 months’ notice under his service 
agreement and received an amount of £346 700 in lieu of base 
salary, and an amount of £65 873 in respect of cash allowances in 
lieu of pension contribution and benefits.

AR Ashworth further received a time pro-rated annual cash bonus 
of £78 892 in respect of 2016, based on performance over the 
period 1 January to 30 June 2016. 

Treatment of AR Ashworth’s outstanding ESOP awards (ie awards 
made in 2014 and 2015) is in line with default treatment for a 
good leaver. Awards will vest on their respective normal vesting 
dates subject to performance measured in the normal manner at 
the end of the respective performance periods, and will be 
reduced on a time pro-rata basis to reflect time served. Based on 
performance to 31 December 2016, 68% of AR Ashworth’s time 
pro-rated 2014 award, ie 29 624 shares, will vest in June 2017. 
Performance for the 2015 award will be measured after 
31 December 2017, and any shares will vest in April 2018. 
As appropriate, any dividends on the above awards will accrue 
and be paid on the relevant vesting dates. AR Ashworth did not 
receive an ESOP award in 2016.

The Annual Report on Remuneration continued

IMPLEMENTATION OF REMUNERATION POLICY FOR 2017
The Committee approved the following salary increases from 1 April 2017:

Executive Director

CT Elphick

M Michael

GE Turner

Audited

Pension and benefits
Under the proposed Policy, the Executive Directors will continue 
to receive cash supplements in lieu of pension and benefits. The 
values will remain unchanged from 2016.

Annual bonus
For 2017, the maximum annual bonus opportunity will remain 
100% of salary. Performance measures will continue to include a 
range of financial, operational and personal objectives that 
support the delivery of the Group’s key strategic goals, with 80% 
linked to business performance and 20% to personal 
performance. Performance measures and targets will be disclosed 
in full on a retrospective basis in next year’s report. As mentioned 
in the Chairman’s statement, from 2017 bonus onwards malus 
and clawback provisions will apply for a period of two years 
following payment, in line with best practice. 

ESOP
In advance of each ESOP cycle, the Committee reviews the 
performance measures and corresponding targets to ensure they 
are appropriately stretching over the performance period. For 
2017 the ESOP will continue to operate on the same basis as 
in 2016. The Chief Executive Officer will receive an award of 
230 000 performance shares (equivalent to 55% of salary) and 
the other Executive Directors will each receive an award of 
170 000 performance shares (equivalent to between 62% 
and 61% of salary).

The performance conditions remain 25% on relative TSR versus 
the FTSE 350 Mining Index, 37.5% on production and 37.5% on 
profit, measured over the three-year performance period ending 
on 31 December 2019. The relative TSR targets remain unchanged 
from 2016 and the profit and production targets will be disclosed 
after the performance period has ended as these targets relate to 
the Company’s business plan and are therefore considered 
commercially sensitive. With effect from ESOP awards made in 
2017, malus and clawback provisions will apply during the vesting 
period and for a period of two years following vesting, 
respectively.

Shareholding guidelines
In order to further align Executive Directors’ interests with those of 
the Company’s other shareholders, the Company is introducing a 
shareholding guideline of 100% of salary from 1 January 2017. 
Until the guideline has been met, Executive Directors will be 
required to retain at least 50% of vested awards under the ESOP 
or any other share-based incentive.

CHAIRMAN AND NON-EXECUTIVE DIRECTOR FEES
Chairman and non-Executive Director fees were reviewed in 
March 2015 when it was agreed that the Chairman’s fee would be 
increased by 10% from £100 000 to £110 000 and the non-
Executive Directors’ fees by 4.8% from £52 500 to £55 000 to bring 
the fees more in line with market fee levels for companies of 
similar size and sector. The fees remained unchanged in 2016 and 
were reviewed again in March 2017 where it was agreed that no 
changes would be made at this time.

PAY FOR PERFORMANCE
The graph below shows the Company’s TSR performance 
compared with the performance of the FTSE 250 (excluding 
investment trusts) and the FTSE 350 Mining Index over the 
eight-year period to 31 December 2016. The FTSE 250 has been 
selected to provide a broad market comparator group, and the 
FTSE 350 Mining Index has been selected because the Group and 
the constituents of the index are affected by similar commercial 
and economic factors. The table below the graph details the Chief 
Executive Officer’s single figure of remuneration and actual

period. As of 31 December 2016, a total of 3 528 548 shares (2.6% 
of issued share capital) have been or may be issued pursuant to

1  Option is a right to acquire shares granted under the plan including, unless indicated otherwise, a nil-cost option. The market price of an ordinary share at the year 
end was 107.50 pence. The highest and lowest closing prices in the year were 147.50 pence and 98.00 pence respectively. Details of the vesting conditions, which are 
subject to audit, for awards made under the ESOP are included in Note 25 of the financial statements and a full set of the rules will be available for inspection at  
the AGM.
2 These awards were granted to M Michael before he became a Director.

The Directors take pleasure in submitting the financial statements 
of the Group for the year ended 31 December 2016.

As a British Virgin Islands (BVI) registered company, 
Gem Diamonds Limited is not obliged to comply with the 
Companies Act, 2006. However, the Directors have elected to 
conform to the requirements of the Companies Act, 2006.

This requires that the Directors present a Strategic Report and a 
Directors’ Report to inform shareholders of the Company and help 
them assess the extent to which the Directors performed their 
duty to promote the success of the Company.

For the purposes of compliance with DTR 4.1.5R(2) and DTR 4.1.8R, 
the required content of the Management Report can be found in 
the Strategic Report and the Directors’ Report, including the 
sections of the Annual Report and Accounts incorporated by 
reference. 

The Strategic Report has been prepared to provide the 
Company’s shareholders with a fair review of the business of 
the Company and a description of the principal risks and 
uncertainties facing it. It may not be relied upon by anyone, 
including the Company’s shareholders, for any other purpose.

The Strategic Report and other sections of this report contain 
forward-looking statements. By their nature, forward-looking 
statements involve several risks, uncertainties and future 
assumptions because they relate to events and/or depend on 
circumstances that may or may not occur in the future which 
could cause actual results and outcomes to differ materially from 
those expressed or implied by the forward-looking statements. 
No assurance can be given that the forward-looking statements 
in the Strategic Report will be realised. Statements about the 
Directors’ expectations, beliefs, hopes, plans, intentions and 
strategies are inherently subject to change and are based on 
expectations and assumptions about future events, circumstances 
and other factors which are, in some cases, outside the 
Company’s control. The information contained in the Strategic 
Report has been prepared based on the knowledge and 
information available to Directors at the date of its preparation 
and the Company does not undertake any obligation to update 
or revise the Strategic Report during the financial year ahead. It is 
believed that the expectations set out in the forward-looking 
statements are reasonable, but they may be affected by a wide 
range of variables which could cause actual results or trends to 
differ materially. In particular, the forward-looking statements 
should be read in context with actual historic information 
provided. The Company’s shareholders are cautioned not to place 
undue reliance on the forward-looking statements. Shareholders 
should note that the Strategic Report has not been audited, but 
the Auditor’s Report does include a statement that the Strategic 
Report is consistent with the financial statements herein.

RELATED-PARTY TRANSACTION
Other than those disclosed in Note 23 of the financial statements, 
the Company did not have any transactions with, nor made loans 
to related parties during the period in which any Director is or 
was interested.

RESOURCE DEVELOPMENT 
Resource development activities were concentrated on 
improving the understanding of existing resources at Letšeng and 
Ghaghoo, and no additional resources and reserves were added. 

The re-assessment of historical geological studies at Letšeng was 
augmented by detailed pit floor mapping and updating of 
geological models, and provided motivation for another phase of 
core drilling in both the Main and Satellite pipes, scheduled to 
start in the first half of 2017. Various techniques are being 
considered in the search for tools to predict not only grade at 
depth, but also the occurrence of the rare high value Type II 
diamonds upon which Letšeng is so dependent.

At Ghaghoo, the evaluation of the lower grade VKMain domain 
was initiated. This domain was originally excluded from the 
underground mining reserves due to its low grade. The sample 
confirmed the reserve estimates. Additional resource delineation 
drilling was completed to confirm geological contacts for levels 
one and two. 

Further details can be found in the mineral resource management 
section on pages 46 to 49.

RESULTS AND DIVIDENDS
The Group’s attributable profit after taxation (before exceptional 
items) amounted to US$17.7 million (2015: US$41.8 million). 
Post-exceptional items, the Group’s attributable loss was 
US$158.8 million.

The Group’s detailed financial results are set out in the financial 
statements section on pages 112 to 169.

The Board has adopted a dividend policy that determines the 
appropriate dividend each year, based on consideration of the 
Company’s cash resources; the level of free cash flow and 
earnings generated during the year; and expected funding 
commitments for capital projects relating to the Group’s growth 
strategy. In current market and operational constraints, 
Gem Diamonds has remained focused on cost discipline and its 
fundamental goal of extracting the maximum value from its 
resources for long-term shareholder value creation. In light of 
the current trading conditions, the disappointing results and the 
reduced cash resources, the Board has not approved a dividend 
for the 2016 results.

Directors’ Report continued

CORPORATE SOCIAL RESPONSIBILITY AND 
SUSTAINABILITY 
A review of health, safety, corporate social responsibility, 
environmental performance and community participation 
is presented in the Sustainable Development Review on 
pages 53 to 58.

GREENHOUSE GAS (GHG) EMISSIONS
Our approach to emission management 
The Group carefully manages its Scope 1 emissions, that is, direct 
GHG emissions that occur from sources that are owned or 
controlled by the Group, for example, stationary and mobile 
combustion. Scope 2 emissions consist of GHG emissions from 
the generation of purchased electricity. The Group focuses on 
reducing these emissions by enhancing efficiencies across its 
operations. Scope 3 emissions that are most material to the 
organisation are carefully managed. These include emissions 
resulting from employee and contractor transportation. 

In 2016, the total carbon footprint for the Group was 
184 765tCO2e (compared to 146 499tCO2e in 2015), primarily 
driven by electricity consumption and mobile and stationary fuel 
combustion. This figure includes the direct GHG emissions (Scope 
1), energy indirect GHG (Scope 2) emissions, and material Scope 3 
emissions, and was calculated with boundaries clearly defined by 
the GHG Protocol Corporate Accounting and Reporting Standard. 

The total Group footprint signifies an increase of 26% from 2015. 
This observed increase is the result of a significant increase in 
diesel usage at Letšeng (an increase of 32% in diesel usage for 
mobile combustion and 70% for stationary combustion). The 
combined increase of 32% for liquid petroleum gas and 25% 
increase in explosives further attributed to this increase. 

Electricity consumption accounted for 68 306tCO2e (37%) of the 
carbon footprint, down from 68 885tCO2e in 2015. The combined 
emissions from mobile and stationary combustion accounted for 
83 974tCO2e (45%) of the total footprint, compared to 
63 914tCO2e (43%) in 2015. The increase year on year has 
resulted from an increase in mining activity and generator use at 
Letšeng due to electricity supply distributions and disruptions 
that were caused by the inclement weather conditions. 

The Group also tracks the tonnes of CO2 emitted per employee 
and per carat recovered (from total Scope 1 and 2 emissions). 
The ratio of 240tCO2e in 2015 per employee has increased to 
347tCO2e per employee in 2016. The increases were directly 
related to an overall increase in the carbon footprint and a 24% 
decrease in permanent employee numbers (down to 446 from 
589). The ratio of 0.66tCO2 per carat in 2015 increased to 1.04tCO2e 
per carat in 2016. This change can be attributed to an increase in 
the total carbon footprint and a decrease of 25% in the number of 
carats recovered during the year as well as the decrease in 
employee numbers. 

As a Group, Gem Diamonds recognises that understanding its 
environmental impact and reducing its level of GHG emissions 
involves more than simply assessing its carbon footprint. 
Therefore, the Group is actively implementing measures to reduce 
emissions, especially at its Letšeng operation.

WATER FOOTPRINT
Fresh water is one of the most important, and increasingly scarce, 
commodities on earth. As water stewards, Gem Diamonds seeks 
to understand the risks posed by water scarcity and pollution and 
undertakes to ensure that water is managed sustainably. As such, 
caring for water sources and monitoring water usage are crucial 
practices in both a commercial and moral respect. Protecting 
water sources helps the Group to maintain its social licence to 
operate. 

The Group’s water footprint (WF) studies provide an integrated 
understanding of its water abstraction and water use. A WF can 
be defined as a measure of freshwater appropriation underlying a 
certain product, including fresh surface water, groundwater 
incorporated into the product or lost during the manufacturing of 
the product. 

The total WF for Gem Diamonds’ operations during the 2016 
technical year was 8 701 985m3. The water sources included 
municipal supplies, groundwater, surface water and direct rainfall. 
The total water recycled and reused by the operations 
was 5 826 137m3 (67%) and the net water usage related to 
evaporation (88%), entrainment (9%), consumption (3%) and dust 
suppression (0.2%). The amount of water that finds its way back 
into the environment through discharge and seepage accounted 
for 3 023 034m3.

Gem Diamonds  Annual Report and Accounts 2016Business overviewManagement reviewOperating reviewGovernanceFinancial statements107

In 2016, total WF for the Group was 37.8m3 per carat and 1.21m3 
per ore tonne treated. The increases were directly related to a 12% 
increase in water usage and 25% decrease in recovered carats. 

It is the Group’s policy to communicate openly with employees 
and encourage dialogue between employees and management. 

The stress WF of the Group, which is the stress placed on the 
water system by mining activity consumption, was found to be 
sustainable.

POLITICAL DONATIONS
The Group made no political donations during 2016.

CORPORATE SOCIAL INVESTMENT (CSI) 
EXPENDITURE
The Group’s CSI expenditure supports initiatives that benefit its 
PACs in the areas of health, education, infrastructure 
development, development of small to medium enterprises and 
general donations to relevant causes in the Group’s PACs. In 2016, 
the Group contributed US$0.4 million to social initiatives, down 
from US$0.6 million in 2015. This decrease can be attributed to a 
shift of focus at Ghaghoo from proactive intervention to project 
maintenance in line with the Group’s objective of honouring its 
commitments to communities while managing the pressures of 
strained market conditions.

EMPLOYEE POLICIES AND INVOLVEMENT
To gain a fuller understanding of matters related to employee 
policies and involvement, this segment should be read in 
conjunction with the information on employment matters 
contained in the Sustainable Development Review in this report 
on pages 53 to 58 together with the full 2016 Sustainable 
Development Report which is available on the Company’s 
website. 

The Group’s employment practices have been developed to 
ensure that the Group attracts and retains the required calibre 
of management and staff by creating an environment which 
incentivises enhanced performance. The health, safety and 
effective performance of employees, together with maintaining 
positive employee relations is of key importance across the 
Group’s operations.

Employees are kept informed about the performance and 
objectives of the Group through direct involvement and access to 
the Company’s website, published information, the circulation of 
press cuttings and Group announcements, as well as continuous 
communication between employees and management.

The Company strives to have a direct relationship between its 
employees and business function management founded on 
quality, leadership, effective communication and trust. The Group 
is committed to the principle and achievement of equal 
opportunities in employment, irrespective of gender, religion, 
race or marital status. Full consideration is given to applications 
from people with disabilities who apply for positions which they 
can adequately fill, having regard for their particular abilities and 
aptitude. Where existing employees become disabled, it is the 
Group’s policy, where practical, to provide continuing 
employment under normal terms and conditions and to provide 
training, career development and promotion to disabled 
employees wherever possible.

The Group sets guidelines and frameworks in respect of Company 
policy on remuneration benefit, performance management, 
career development, succession planning, recruitment, expatriate 
employment and for the alignment of human resources 
management and policy with international best practice. Each 
operating unit manages its human resources requirements locally, 
within the Group’s guidelines and framework.

CORPORATE GOVERNANCE
The UK Financial Conduct Authority’s Disclosure Guidance and 
Transparency Rules (DTR 7.2) require that certain information be 
included in a corporate governance statement set out in the 
Directors’ Report. The Group has an existing practice of issuing a 
separate Corporate Governance Code Compliance Report as part 
of its Annual Report. The information required by the Disclosure 
Guidance and Transparency Rules and the UK Financial Conduct 
Authority’s Listing Rules (LR 9.8.6) is located on pages 66 to 73 of 
this Annual Report.

GOING CONCERN 
The Company’s business activities, together with the factors likely 
to affect its future development, performance and position are set 
out in the Strategic Report on pages 2 to 59. The financial position 
of the Company, its cash flows and liquidity position are described 
in the Strategic Report on pages 34 to 39. In addition, Note 24 and 
Note 26 to the financial statements include the Company’s 
objectives, policies and processes for managing its capital; its 
financial risk management objectives; details of its financial 
instruments; and its exposures to credit and liquidity risk.

Directors’ Report continued

After making enquiries which review forecasts and budgets, 
timing of cash flows, borrowing facilities and sensitivity analyses 
and considering the uncertainties described in this report either 
directly or by cross-reference, the Directors have a reasonable 
expectation that the Group has adequate financial resources to 
continue in operational existence for the foreseeable future. For 
this reason, they continue to adopt the going-concern basis in 
preparing the Annual Report and Accounts of the Company.

VIABILITY STATEMENT
In accordance with provision C.2.2 of the 2014 revision of the UK 
Corporate Governance Code, the Directors have assessed the 
prospect of the Company over a longer period of 12 months as 
required by the ‘Going Concern’ provision. The viability statement 
can be found in the Strategic Report on page 25.

DIRECTORS
The Directors, as at the date of this report, are listed on pages 
62 and 63 together with their biographical details. Details of the 
Directors’ interests in shares and share options of the Company 
can be found in the Annual Report on Remuneration on 
page 103.

Directors who held office during the year and date of 
appointment/resignation 

face a range of penalties including private or public censure, fines 
and/or imprisonment. In line with normal market practice, the 
Group believes that it is in its best interests to protect the 
individuals prepared to serve on its Board from the consequences 
of innocent error or omission, as this enables the Group to attract 
prudent individuals to act as Directors.

Therefore, the Group has, and continues to maintain, at its 
expense, a Director and Officer’s liability insurance policy to 
provide indemnity, in certain circumstances, for the benefit of 
Directors and other Group personnel. The insurance policy does 
not provide cover where the Director or Group personnel 
member has acted fraudulently or dishonestly.

In accordance with the Company’s Articles of Association, the 
Company has and continues to maintain indemnities granted by 
the Company to the Directors of the Company and the 
Company’s associated companies to the extent permitted by and 
consistent with BVI law and the UK Companies Act, 2006 and rules 
made by the UK Listing Authority.

Re-election of Directors
The Articles of Association (81) provides that a third of Directors 
retire annually by rotation and, if eligible, offer themselves for 
re-election. However, in accordance with the Code, at each AGM 
all the Directors retire and, subject to being eligible, offer 
themselves for re-election. Each Director has been the subject of 
a recent Board evaluation.

Protection available to Directors 
By law, Directors are ultimately responsible for most aspects of the 
Group’s business dealings. Consequently, they face potentially 
significant personal liability under criminal or civil law, or the UK 
Listing, Prospectus and Disclosure and Transparency Rules and 

As at 14 March 2017, there were 138.4 million fully paid ordinary 
shares of £0.01 each in issue and listed on the official list 
maintained by the FCA in its capacity as the UK Listing Authority.

The Company has one class of ordinary shares. Shareholders have 
the right to receive notice of and attend, speak and vote at any 
general meeting of the Company. Each shareholder who is 
present in person (or, being a corporation, by representative) or 
by proxy at a general meeting on a show of hands has one vote 
and, on a poll, every such holder present in person (or, being a 
corporation, by representative) or by proxy shall have one vote 
in respect of every ordinary share held by them. To be valid, the 
appointment of a proxy to vote at a general meeting must be 
received not less than 48 hours before the time appointed for 
holding the meeting. In addition, the holders of ordinary shares 
have the right to participate in dividends and other distributions 
according to their respective rights and interests in the profit of 
the Company.

Glenn Turner
Company Secretary

14 March 2017

There are no shareholders who carry any special rights with 
regard to the control of the Company. The Company is not aware 
of any agreements between holders of securities which may 
result in restrictions on transfers or voting rights, save as 
mentioned below.

There are no restrictions on the transfer of ordinary shares other 
than:
 u as set out in the Company’s Articles of Association;
 u certain restrictions may from time to time be imposed by laws 

and regulations; and

 u pursuant to the Company’s share dealing code whereby the 

Directors and employees of the Company require approval to 
deal in the Company’s ordinary shares.

At the AGM held in 2016, shareholders authorised the Company 
to make on-market purchases of up to 13 829 646 of its ordinary 
shares, representing approximately 10% of the Company issued 
share capital at that time. During 2016, the Company did not 
make any on-market or off-market purchases of its shares or 
shares under any buy-back programme. Shareholders will be 
asked at the 2017 AGM to renew this authority. The Directors have 
no present intention to exercise this authority, if granted. Details 
of deadlines for exercising voting rights and proxy appointments 
will be set out in the 2017 Notice of AGM.

MAJOR INTERESTS IN SHARES
Details of the major interests (at or above 3%) in the issued 
ordinary shares of the Company are set out in the UK Corporate 
Governance Code Compliance Report on page 73.

DIRECTORS’ INTERESTS
No Director had, at any time during the year, a material interest in 
any contract of significance in relation to the Company’s business. 
The interest of Directors in the shares of the Company is included 
in the Annual Report on Remuneration on page 103.

CREDITORS’ PAYMENT PRACTICE
In view of the international nature of the Group’s operations, there 
is no specific Group-wide policy in respect of payments to 
suppliers. Individual operating companies are responsible for 
agreeing terms and conditions for their business transactions and 
ensuring that suppliers are aware of the terms of payment. It is 
Group practice that payments are made in accordance with those 
terms, provided that all trading terms and conditions have been 
met by the supplier. Trade creditors at 31 December 2016 
represented 28 days of the Company’s annual purchases.

Responsibility Statement of the Directors in Respect of 
the Annual Report and Financial Statements

The Directors are responsible for preparing the Annual Report and 
the Group financial statements in accordance with International 
Financial Reporting Standards (IFRS). Having taken advice from 
the Audit Committee, the Board considers the report and 
accounts taken as a whole, are fair, balanced and understandable 
and that they provide the information necessary for shareholders 
to assess the Company’s performance, business model and 
strategy.

The Strategic Report and Directors’ Report include a fair review of 
the development and performance of the business and the 
position of the Company and the undertakings included in the 
consolidation taken as a whole, together with a description of the 
principal risks and uncertainties that they face.

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Group’s 
transactions and disclose, with reasonable accuracy at any time, 
the financial position of the Group. They are also responsible for 
safeguarding the assets of the Group and hence for taking 
reasonable steps for the prevention and detection of fraud and 
other irregularities.

The Directors confirm that the financial statements, prepared in 
accordance with IFRS, give a true and fair view of the assets, 
liabilities, financial position and profit of the Company and the 
undertakings included in the consolidation taken as a whole. In 
addition, suitable accounting policies have been selected and 
applied consistently.

PREPARATION OF THE FINANCIAL STATEMENTS
The Directors must not approve the financial statements unless 
they are satisfied that they give a true and fair view of the state of 
affairs of the Group, and of their profit or loss for that period. In 
preparing the Group financial statements, the Directors are 
required to:
 u select suitable accounting policies and then apply them 

consistently; 

 u make judgements and estimates that are reasonable and 

prudent;

 u state whether they have been prepared in accordance with 

IFRS;

 u state whether applicable IFRS have been followed, subject to 
any material departures disclosed and explained in the Group 
financial statements; and

 u prepare the financial statements on the going-concern basis 
unless it is inappropriate to presume that the Group will 
continue in business.

Information, including accounting policies, has been presented in 
a manner that provides relevant, reliable, comparable and 
understandable information, and additional disclosures have 
been provided when compliance with the specific requirements 
in IFRS have been insufficient to enable users to understand the 
financial impact of particular transactions, other events and 
conditions on the Group’s financial position and financial 
performance. Where necessary, the Directors have made 
judgements and estimates that are reasonable and prudent.

The Directors of the Company have elected to comply with the 
Companies Act 2006, in particular the requirements of Schedule 8 
to The Large and Medium-sized Companies and Groups 
(Accounts and Reports) Regulations 2008 of the United Kingdom 
pertaining to Directors’ remuneration which would otherwise only 
apply to companies incorporated in the UK.

Independent Auditor’s Report to the 
Members of Gem Diamonds Limited

OUR OPINION ON THE FINANCIAL STATEMENTS
In our opinion:
 u the financial statements of Gem Diamonds Limited (the Group) give a true and fair view of the state of the Group’s affairs as at 

31 December 2016 and of its profit for the year then ended; and

 u the financial statements have been properly prepared in accordance with IFRS. 

The financial reporting framework that has been applied in their preparation is applicable law and International Financial Reporting 
Standards.

OVERVIEW OF OUR AUDIT APPROACH

Risks of material 
misstatement

 u Revenue recognition
 u Assessing the Ghaghoo development asset for impairment

Audit scope

 u We performed a full scope audit of three components and audit procedures on specific balances for a 

further six components

 u The components where we performed full or specific audit procedures accounted for 99% of pre-tax 

profit, 100% of revenue and 99% of total assets

Materiality

 u Overall Group materiality was US$2.6 million which represents 5% of pre-tax profit; excluding exceptional 
items. We exclude the exceptional items, being the impairment on Ghaghoo and the abandonment of 
the Calibrated Diamonds Investment Holdings (Proprietary) Limited Group (CDIH), as they represent 
unusual non-recurring events

Members of Gem Diamonds Limited continued

OUR ASSESSMENT OF RISK OF MATERIAL MISSTATEMENT
We identified the risks of material misstatement described below as those that had the greatest effect on our overall audit strategy, the 
allocation of resources in the audit and the direction of the efforts of the audit team. In addressing these risks, we have performed the 
procedures below which were designed in the context of the financial statements as a whole and, consequently, we do not express any 
opinion on these individual areas.

Our response to the risk

Revenue recognition

Key observations 
communicated to the 
Audit Committee

Refer to the Audit Committee Report (page 76); Accounting policies (page 139); and Note 2 of the Annual Financial Statements (page 144).

The Group recognised revenue of US$189.8 million 
in the year (2015: US$249.5 million). Diamonds are 
sold through the following revenue streams: 
 u Rough diamonds sold on tender; 
 u Selected diamonds sold through partnership 

arrangements;

 u Diamonds extracted for purposes of 

manufacturing and sold thereafter in polished 
form; and

 u Diamonds sold through joint operation 

arrangements.

We focused on this area due to the inherent risk 
related to the recognition and measurement of 
revenue, particularly on partnership arrangements 
and diamonds extracted for purposes of 
manufacturing (cutting and polishing). 

For partnership arrangements, revenue is earned on 
the sale of the rough diamond, with an additional 
uplift recognised on the polished margin achieved. 
Judgement is involved in determining when the 
risks and rewards of ownership transfer on the sale 
of the rough diamond.

For diamonds extracted for purposes of 
manufacturing, no revenue is recognised by the 
Group until the diamonds are sold to third parties; 
as a result, there are a number of intercompany 
transactions that must be eliminated in the 
consolidated financial statements. There is a risk 
relating to the completeness of sales recognised 
through the extraction process in light of the 
polishing losses that result from the manufacturing 
process.

 u We considered all diamond revenue streams as 
significant, and therefore, observed the design 
effectiveness of the controls around the revenue 
process in understanding management’s internal 
processes and the control environment. 
 u We verified management’s recognition of 

We concluded that 
revenue recognised in 
the year has been

of our procedures. 

revenue, covering all revenue streams of the 
Group. This involved agreeing revenue 
transactions to underlying customer 
agreements, invoices and supporting 
calculations to confirm the accuracy and 
occurrence of the sales recorded.

 u For partnership arrangements, we assessed the 

appropriateness of management’s judgement, in 
determining when risks and rewards are 
transferred, by reviewing correspondence 
between management and the partner that 
confirms no managerial involvement after the 
sale of the rough stone. 

 u We assessed the accounting treatment of all 

stones sold through joint operation 
arrangements ensuring they are recognised in 
accordance with IFRS 11 Joint Arrangements.  

 u We performed cut off testing at year end by 
selecting transactions close to the year end, 
ensuring the revenue was recognised in the 
correct period. 

 u We also reviewed management’s reconciliation 
of inventory movements from stones recovered 
and exported from Letšeng to those sold during 
the year and the remaining inventory on hand at 
Gem Diamonds Marketing Services at year end 
to validate the completeness of revenue.

Audit Committee

Refer to the Audit Committee Report (page 77); Accounting policies (page 141); and Note 12 of the Annual Financial Statements (page 152).

We focused on this area due to the size of the 
Ghaghoo development asset (pre-impairment) 
that had increased to US$130.7 million from 
US$117.6 million (post-impairment) in June 2016 
(2015: US$141.9 million) and because of the 
judgements and estimates involved in determining 
the expected future performance of the mine. 

Management’s decision to place the mine on care 
and maintenance in February 2017 was determined 
to be evidence of the existence of impairment 
indicators at year end. 

Having reassessed Ghaghoo’s recoverable amount, 
management has provided for the impairment of 
US$170.8 million for the year ended 31 December 
2016 (which includes the US$40.0 million 
recognised at 30 June 2016), being the 
development asset and all property, plant and 
equipment comprising the Ghaghoo cash-
generating unit.

Management has classified the Ghaghoo 
US$25.0 million facility as current at year end as it is 
required to be repaid once the mine is placed on 
care and maintenance. 

 u We tested the methodology applied in the 
value-in-use calculation relative to the 
requirements of International Accounting 
Standards (IAS) 36 Impairment of Assets, and the 
mathematical accuracy of management’s model. 

 u We obtained an understanding of and assessed 
the basis for key underlying assumptions in the 
mine’s business plan: focussing on diamond 
prices and discount rates. 

 u We challenged management’s cash flow 

forecasts by considering evidence available to 
support assumptions for reasonableness and the 
reliability of past forecasts.

 u We checked that hindsight was not used in 
determining the amount of the year end 
impairment.

 u We engaged EY specialists to assess the 

reasonableness of the methodology used in 
determining the discount rate and challenge 
management’s price and discount rate 
assumptions by benchmarking against industry 
peers.

 u We performed sensitivity testing on the price 

and discount rate assumptions used. 
 u We assessed the implications of the 

announcement, post-balance sheet date, to 
place the mine on care and maintenance.
 u Verified that all required disclosures in the 
consolidated financial statements were 
complete and adequately reflected the outcome 
of management’s care and maintenance 
decision.

Based on the above 
findings we note that 
the model is sensitive to 
any changes in 
assumptions. Given the 
current market 
conditions and the 
history of the asset, we 
believe any such 
changes that would 
result in less than a full 
impairment would be 
optimistic. Therefore we 
concur with 
management’s decision 
to fully impair the 
non-current assets.

We believe 
management’s 
recognition and related 
disclosure of the 
impairment in the 
financial statements to 
be reasonable and in 
line with IAS 36 
Impairment. 

The risk around the key judgements relating to production start date is no longer applicable following the decision to place the mine on 
care and maintenance.

THE SCOPE OF OUR AUDIT 
Tailoring the scope
Our assessment of audit risk, our evaluation of materiality and our 
allocation of performance materiality determine our audit scope 
for each entity within the Group. Taken together, this enables us 
to form an opinion on the consolidated financial statements. We 
take into account size, risk profile, the organisation of the Group 
and effectiveness of Group-wide controls, changes in the business 
environment and other factors when assessing the level of work 
to be performed at each entity.

In assessing the risk of material misstatement to the Group 
financial statements, and to ensure we had adequate quantitative 
coverage of significant accounts in the financial statements, of 
the 20 reporting components of the Group, we selected 
13 components (the remaining seven components are dormant) 
covering entities within Belgium, Botswana, Lesotho, South Africa, 
United Arab Emirates, and the United Kingdom, which represent 
the principal business units within the Group.

Of the 13 components selected, we performed a full scope audit 
of three components which were selected based on their size or 
risk characteristics. For six components (specific scope 
components), we performed audit procedures on specific 
accounts within that component that we considered had the 
potential for the greatest impact on the significant accounts in 
the financial statements either because of the size of these 
accounts or their risk profile.

The components where we performed audit procedures 
accounted for 99% (2015: 99%) of the Group’s pre-tax profit, 
100% (2015: 100%) of the Group’s revenue and 97% (2015: 97%) 
of the Group’s total assets. For the current year, the full scope 
components contributed 98% (2015: 98%) of the Group’s pre-tax 
profit, 98% (2015: 98%) of the Group’s revenue and 95% 
(2015: 95%) of the Group’s total assets. The specific scope 
components contributed 1% (2015: 1%) of the Group’s pre-tax 
profit, 2% (2015: 2%) of the Group’s revenue and 2% (2015: 2%) of 
the Group’s total assets. The audit scope of these components 
may not have included testing of all significant accounts of the 
component but contributed to the coverage of significant 
accounts tested for the Group. 

Of the remaining four components that together represent 1% of 
the Group’s pre-tax profit, we performed other procedures, 
including analytical reviews, testing of consolidation journals and 
intercompany eliminations, and assessing entity level controls to 
respond to any potential risks of material misstatement to the 
Group financial statements.

CHANGES FROM THE PRIOR YEAR 
Our scope allocation in the current year is broadly consistent with 
2015 in terms of overall coverage of the Group, however, we did 
make some changes in the identity of components subject to full 
and specific scope audit procedures. Changes in our scope since 
the 2015 audit included moving the audit of the Gem Diamonds 
Limited standalone entity from full audit scope to a specific scope 
component due to only specific accounts having been 
considered to have a potential material impact on the significant 
accounts in the financial statements. 

INVOLVEMENT WITH COMPONENT TEAMS 
In establishing our overall approach to the Group audit, we 
determined the type of work that needed to be undertaken at 
each of the components by us, as the primary audit engagement 
team, or by component auditors from other EY global network 
firms operating under our instruction. For the three full scope 
components, audit procedures were performed on one of these 
directly by the primary audit team and by our component audit 
teams in Botswana and Lesotho. For the six specific scope 
components, audit procedures were performed on three of these 
directly by the primary audit team. Of the three specific scope 
components where the work was performed by component 
auditors, we determined the appropriate level of involvement to 
enable us to determine that sufficient audit evidence had been 
obtained as a basis for our opinion on the Group as a whole.

The Group audit team continued to follow a programme of 
planned visits that has been designed to ensure that the Senior 
Statutory Auditor visits each of the full scope locations at least 
once a year. During the current year’s audit cycle, visits were 
undertaken by the primary audit team to the component teams 
in Belgium, Lesotho, and South Africa. The Global Team Planning 
Event was held in South Africa with representatives of the 
components from Botswana, Lesotho and South Africa all 
attending. The primary audit team also held a separate team 
planning event with the component audit team in Belgium. 
Dependent on the timing of our visits, these involved discussion 
of the audit approach with the component team and any issues 
arising from their work, consideration of the approach to revenue 
recognition, and meeting with local management. The primary 
team interacted regularly with the component teams where 
appropriate during various stages of the audit, reviewed key 
working papers, attended audit closing meetings, including 
discussions of fraud and error, and were responsible for the scope 
and direction of the audit process. This, together with the 
additional procedures performed at Group level, gave us 
appropriate evidence for our opinion on the Group financial 
statements.

OUR APPLICATION OF MATERIALITY 
We apply the concept of materiality in planning and performing 
the audit, in evaluating the effect of identified misstatements on 
the audit and in forming our audit opinion. 

Materiality
The magnitude of an omission or misstatement that, individually or in 
the aggregate, could reasonably be expected to influence the 
economic decisions of the users of the financial statements. 
Materiality provides a basis for determining the nature and extent of 
our audit procedures.

We determined materiality for the Group to be US$2.6 million 
(2015: US$5.4 million), which is 5% (2015: 5%) of pre-tax profits, 
excluding exceptional items. We have excluded the exceptional 
item, being the impairment, recognised on Ghaghoo and the 
abandonment of the CDIH group, as they represent non-recurring 
events. We consider pre-tax profit provides us with the most 
relevant performance measure to the stakeholders of the entity 
given the production stage of the Group’s Letšeng mine. Our 
planning materiality has decreased by 52% compared to 
2015 given the reduction in pre-tax profit recognised by the 
Group in 2016. 

During the course of our audit, we reassessed initial materiality 
and changed our final materiality to reflect the actual reported 
performance of the Group in the year. 

Performance materiality
The application of materiality at the individual account or balance 
level. It is set at an amount to reduce to an appropriately low level the 
probability that the aggregate of uncorrected and undetected 
misstatements exceeds materiality.

On the basis of our risk assessments, together with our 
assessment of the Group’s overall control environment, our 
judgement was that performance materiality was 50% 
(2015: 50%) of our planning materiality, namely US$1.3 million 
(2015: US$2.7 million). We have set performance materiality at this 
percentage due to our expectation of misstatements identified 
based on prior experience. 

Audit work at component locations for the purpose of obtaining 
audit coverage over significant financial statement accounts is 
undertaken based on a percentage of total performance 
materiality. The performance materiality set for each component 
is based on the relative scale and risk of the component to the 
Group as a whole and our assessment of the risk of misstatement 
at that component. In the current year, the range of performance 
materiality allocated to components was US$0.2 million to 
US$1 million (2015: US$0.4 million to US$1.4 million).

Independent Auditor’s Report to the 
Members of Gem Diamonds Limited continued

Reporting threshold
An amount below which identified misstatements are considered as 
being clearly trivial.

We have agreed with the Audit Committee that we would report 
to them all uncorrected audit differences in excess of 
US$0.1 million (2015: US$0.2 million), which is set at 5% of 
planning materiality, as well as differences below that threshold 
that, in our view, warranted reporting on qualitative grounds. 

We evaluate any uncorrected misstatements against both the 
quantitative measures of materiality discussed above and in light 
of other relevant qualitative considerations in forming our 
opinion.

SCOPE OF THE AUDIT OF THE FINANCIAL STATEMENTS
An audit involves obtaining evidence about the amounts and 
disclosures in the financial statements sufficient to give 
reasonable assurance that the financial statements are free from 
material misstatement, whether caused by fraud or error. This 
includes an assessment of: whether the accounting policies are 
appropriate to the Group’s circumstances and have been 
consistently applied and adequately disclosed; the 
reasonableness of significant accounting estimates made by the 
directors; and the overall presentation of the financial statements. 
In addition, we read all the financial and non-financial information 
in the Annual Report to identify material inconsistencies with the 
audited financial statements and to identify any information that 
is apparently materially incorrect based on, or materially 
inconsistent with, the knowledge acquired by us in the course of 
performing the audit. If we become aware of any apparent 
material misstatements or inconsistencies we consider the 
implications for our report.

RESPECTIVE RESPONSIBILITIES OF DIRECTORS AND 
AUDITOR
As explained more fully in the Directors’ responsibilities statement 
set out on page 112, the Directors are responsible for the 
preparation of the financial statements and for being satisfied that 
they give a true and fair view. Our responsibility is to audit and 
express an opinion on the financial statements in accordance 
with applicable law and International Standards on Auditing (UK 
and Ireland). Those standards require us to comply with the 
Auditing Practices Board’s Ethical Standards for Auditors.

In addition, the Company has also instructed us to:

practices about its administrative, management and supervisory 
bodies and their committees) have been complied with if 
applicable.

This report is made solely to the Company’s members, as a body, 
in accordance with the terms of our engagement letter dated 
4 March 2016.

Our audit work has been undertaken so that we might state to 
the Company’s members those matters we are required to state 
to them in an auditor’s report and for no other purpose. To the 
fullest extent permitted by law, we do not accept or assume 
responsibility to anyone other than the Company and the 
Company’s members as a body, for our audit work, for this report,

NOTES TO THE FINANCIAL STATEMENTS (continued)

Corporate information (continued)
Segment information
1.1.3
For management purposes, the Group is organised into geographical units as its risks and required rates of return 
are affected predominantly by differences in the geographical regions of the mines and areas in which the Group 
operates or areas in which operations are managed. The main geographical regions and the type of products and 
services from which each reporting segment derives its revenue from are:

 u Lesotho (diamond mining activities);
 u Botswana (diamond mining activities through Ghaghoo and sales and marketing of diamonds through Gem 

Diamonds Marketing Botswana (Proprietary) Limited;

 u Belgium (sales, marketing and manufacturing of diamonds); and
 u BVI, RSA and UK (technical and administrative services).

Management monitors the operating results of the geographical units separately for the purpose of making 
decisions about resource allocation and performance assessment. 

Segment performance is evaluated based on operating profit or loss. Intersegment transactions are entered into under 
normal arm’s-length terms in a manner similar to transactions with third parties. Segment revenue, segment expenses 
and segment results include transactions between segments. Those transactions are eliminated on consolidation.

Segment revenue is derived from mining activities, polished manufacturing margins, and Group services. 

During the period, an immaterial operation, CDIH, operating out of South Africa and part of the Belgium segment, 
which developed and maintained laser diamond shaping and cutting technology and machinery, was abandoned 
due to its inability to generate profits during current market conditions and therefore its results have been excluded.

The following table presents revenue and profit, and asset and liability information from operations regarding the 
Group’s geographical segments:

Corporate information (continued)
1.1.3 Corporate information (continued)

Included in annual revenue for the current year is revenue from a single customer which amounted to 
US$31.3 million arising from sales reported in the Lesotho and Belgium segment. 

Segment liabilities do not include net deferred tax liabilities of US$65.6 million.

Total sales for the current year are lower than that of the prior year mainly as a result of the lower frequency of 
exceptional large diamonds being recovered at the Lesotho segment, resulting in lower diamond prices achieved.

Included in annual revenue for the 2015 year was revenue from a single customer which amounted to 
US$46.7 million arising from sales reported in the Lesotho and Belgium segment.

Segment liabilities do not include net deferred tax liabilities of US$50.4 million.

Total sales for 2015 were lower than that of 2014 mainly as a result of market conditions and lower diamond prices 
achieved at the Lesotho segment, together with lower number of carats sold due to production cut-off periods.

NOTES TO THE FINANCIAL STATEMENTS (continued)
1.2

Summary of significant accounting policies
1.2.1  Basis of presentation

The financial statements of the Group have been prepared in accordance with International Financial Reporting Standards 
(IFRS). These financial statements have been prepared under the historical cost basis. The accounting policies have been 
consistently applied except for the adoption of the new standards and interpretations detailed below.

The functional currency of the Company and certain of its subsidiaries is US dollar, which is the currency of the 
primary economic environment in which the entities operate. All amounts are expressed in US dollar. The financial 
statements of subsidiaries whose functional and reporting currency is in currencies other than US dollar have been 
converted into US dollar on the basis as set out in Note 1.2.16, Foreign currency translations.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting 
estimates. It also requires management to exercise its judgement in the process of applying the Group’s accounting 
policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates 
are significant to the financial statements are disclosed in Note 1.2.26, Critical accounting estimates and judgements.

The Group has also adopted the following standards and interpretations from 1 January 2016:

Standards issued but not yet effective 
Certain new standards, amendments and interpretations to existing standards have been published that are 
mandatory for the Group’s accounting periods beginning after 1 January 2017 or in later periods, which the Group 
has decided not to adopt early.

The Group is in the process of assessing the impact of these standards on the financial statements.

IFRS 15 Revenue from Contracts with Customers
IFRS 15 will replace IAS 18 Revenue and IAS 11 Construction Contracts and establishes a unified framework for 
determining the timing, measurement and recognition of revenue. The principle of the new standard is to recognise 
revenue as performance obligations are met rather than based on the transfer of risks and rewards. The effective 
date of the standard is 1 January 2018. 

The Group is currently reviewing the potential impact of IFRS 15 with the primary focus being understanding those 
sales contracts where the timing and amount of revenue recognised could differ under IFRS 15. As the Group’s 
revenue is predominantly derived from rough diamond sales in which the transfer of risks and rewards coincides 
with the fulfilment of performance obligations, the timing and amount of revenue recognised is unlikely to be 
affected for these sales. It is currently anticipated that IFRS 15 will have an impact on the timing and amount of 
revenue recognised relating to uplift on partnership derived on the sale of polished diamonds. As these revenue 
streams have represented between 1.4% – 2.6% of total revenue generated in the past five years, it is not anticipated 
to have a significant impact on the results.

IFRS 15 also includes disclosure requirements including qualitative and quantitative information about contracts 
with customers to help users of the financial statements understand the nature, amount, timing and uncertainty 
of revenue. The Group will start developing a transition plan to identify and implement the required changes 
during 2017. The Group expects to adopt this standard retrospectively.

NOTES TO THE FINANCIAL STATEMENTS (continued)
1.2

Summary of significant accounting policies (continued)
1.2.1

Basis of presentation (continued)
IFRS 16 Leases
Under the new standard, a lessee is in essence required to:
 u recognise all right of use assets and lease liabilities, with the exception of short term (under 12 months) and low 
value leases, on the balance sheet. The liability is initially measured at the present value of future lease payments 
for the lease term. This includes variable lease payments that depend on an index or rate but excludes other 
variable lease payments. The right of use asset reflects the lease liability, initial direct costs, any lease payments 
made before the commencement date of the lease, less any lease incentives and, where applicable, provision for 
dismantling and restoration;

 u recognise depreciation of right of use assets and interest on lease liabilities in the income statement over the 

lease term; and

 u separate the total amount of cash paid into a principal portion (presented within financing activities) and interest 

portion (which the Group presents in operating activities) in the cash flow statement.

This standard will have an impact on the Group’s earnings and it must be implemented retrospectively, either with 
the restatement of comparatives or with the cumulative impact of application recognised as at 1 January 2019 
under the modified retrospective approach. 

Under IFRS 16 the present value of the Group’s operating lease commitments as defined under the new standard, 
excluding low value leases and short-term leases, will be shown as right of use assets and as lease liabilities on the 
balance sheet. Information on the undiscounted amount of the Group’s operating lease commitments under IAS 17, 
the current leasing standard, is disclosed in Note 22. The Group is considering the available options for transition. 

Over the next two years, the Group will focus on the identification of the provisions of the standard which will most 
impact the Group.

Business environment and country risk
The Group’s operations are subject to country risk being the economic, political and social risks inherent in doing 
business in certain areas of Africa and Europe. These risks include matters arising out of the policies of the 
government, economic conditions, imposition of or changes to taxes and regulations, foreign exchange rate 
fluctuations and the enforceability of contract rights.

The consolidated financial information reflects management’s assessment of the impact of these business 
environments on the operations and the financial position of the Group. The future business environment may differ 
from management’s assessment.

1.2.2 Going concern

The Company’s business activities, together with the factors likely to affect its future development, performance 
and position are set out in the Strategic Review on pages 40 to 45 and pages 50 to 52. The financial position  
of the Company, its cash flows and liquidity position are described in the Strategic Review on pages 34 to 39. In 
addition, Note 24, Financial risk management, includes the Company’s objectives, policies and processes for 
managing its capital; its financial risk management objectives; details of its financial instruments; and its exposures 
to credit risk and liquidity risk.

After making enquiries which include reviews of forecasts and budgets, timing of cash flows, borrowing facilities and 
sensitivity analyses and considering the uncertainties described in this report either directly or by cross-reference, 
the Directors have a reasonable expectation that the Group and the Company have adequate financial resources to 
continue in operational existence for the foreseeable future. For this reason, they continue to adopt the going-
concern basis in preparing the Annual Report and Accounts of the Company.

These financial statements have been prepared on a going-concern basis which assumes that the Group will be able 
to meet its liabilities as they fall due for the foreseeable future.

1.2.3

Basis of consolidation
The consolidated financial statements incorporate the financial statements of the Company and entities controlled 
by the Company.

NOTES TO THE FINANCIAL STATEMENTS (continued)

Summary of significant accounting policies (continued)
1.2.3

Basis of consolidation (continued)
Subsidiaries 
Subsidiaries are consolidated from the date of their acquisition, being the date on which the Group obtains control, 
and continue to be consolidated until the date that such control ceases. An investor controls an investee when it is 
exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those 
returns through its power over the investee. To meet the definition of control in IFRS 10, all three of the following 
criteria must be met:
(a)   an investor has power over an investee;
(b)   the investor has exposure, or rights, to variable returns from its involvement with the investee; and
(c)   the investor has the ability to use its power over the investee to affect the amount of the investor’s returns.

1.2.4

The financial statements of subsidiaries used in the preparation of the consolidated financial statements are 
prepared for the same reporting year as the parent company and are based on consistent accounting policies. All 
intragroup balances and transactions, including unrealised profits arising from them, are eliminated in full.

Non-controlling interests 
Non-controlling interests represent the equity in a subsidiary not attributable, directly or indirectly, to the parent 
company and is presented separately within equity in the consolidated statement of financial position, separately 
from equity attributable to owners of the parent. Losses within a subsidiary are attributed to the non-controlling 
interest even if that results in a deficit balance.

Exploration and evaluation expenditure
Exploration and evaluation activity involves the search for mineral resources, the determination of technical 
feasibility and the assessment of commercial viability of an identified resource. Exploration and evaluation activity 
includes:
 u acquisition of rights to explore;
 u researching and analysing historical exploration data;
 u gathering exploration data through topographical, geochemical and geophysical studies;
 u exploratory drilling, trenching and sampling;
 u determining and examining the volume and grade of the resource;
 u surveying transportation and infrastructure requirements; and
 u conducting market and finance studies.

Administration costs that are not directly attributable to a specific exploration area are charged to the income 
statement. Licence costs paid in connection with a right to explore in an existing exploration area are capitalised 
and amortised over the term of the permit.

Exploration and evaluation expenditure is capitalised as incurred. Capitalised exploration expenditure is recorded as 
a component of property, plant and equipment at cost less accumulated impairment charges. As the asset is not 
available for use, it is not depreciated.

All capitalised exploration and evaluation expenditure is monitored for indications of impairment. Where a potential 
impairment is indicated, assessments are performed for each area of interest in conjunction with the group of 
operating assets (representing a cash-generating unit (CGU)) to which the exploration is attributed. To the extent 
that exploration expenditure is not expected to be recovered, it is charged to the income statement. Exploration 
areas where reserves have been discovered, but require major capital expenditure before production can begin, are 
continually evaluated to ensure that commercial quantities of reserves exist or to ensure that additional exploration 
work is under way as planned.

1.2.5 Development expenditure

When proved reserves are determined and development is sanctioned, capitalised exploration and evaluation 
expenditure is reclassified within property, plant and equipment to development expenditure. As the asset is not 
available for use, during the development phase, it is not depreciated. On completion of the development, any 
capitalised exploration and evaluation expenditure already capitalised to development asset, together with the 
subsequent development expenditure, is reclassified within property, plant and equipment to mining assets and 
depreciated on the basis as laid out in Note 1.2.6, Property, plant and equipment.

All development expenditure is monitored for indicators of impairment annually.

1.2.6

Property, plant and equipment
Property, plant and equipment are recorded at cost less accumulated depreciation and accumulated impairment 
losses. Cost includes expenditure that is directly attributable to the acquisition and construction of the items, among 
others, professional fees, and for qualifying assets, borrowing costs capitalised in accordance with the Group’s 
accounting policies.

Subsequent costs to replace a component of an item of property, plant and equipment that is accounted for 
separately, is capitalised when the cost of the item can be measured reliably, with the carrying amount of the 
original component being written off. All repairs and maintenance are charged to the income statement during the 
financial period in which they are incurred.

Depreciation commences when an asset is available for use. Depreciation is charged so as to write off the 
depreciable amount of the asset to its residual value over its estimated useful life, using a method that reflects the 
pattern in which the asset’s future economic benefits are expected to be consumed by the Group.

Pre-production stripping costs
Costs associated with removal of waste overburden are classified as stripping costs.

The capitalisation of pre-production stripping costs as part of exploration and development assets ceases when the 
mine is commissioned and ready for production. Subsequent stripping activities that are undertaken during the 
production phase of a surface mine may create two benefits, being either the production of inventory or improved 
access to the ore to be mined in the future. Where the benefits are realised in the form of inventory produced in the 
period, the production stripping costs are accounted for as part of the cost of producing those inventories. Where 
production stripping costs are incurred and where the benefit is the creation of mining flexibility and improved 
access to ore to be mined in the future, the costs are recognised as a non-current asset, referred to as a ‘stripping 
activity asset’, if:
(a)   future economic benefits (being improved access to the orebody) are probable;
(b)  the component of the orebody for which access will be improved can be accurately identified; and
(c)  the costs associated with the improved access can be reliably measured.

The stripping activity asset is separately disclosed in Note 9, Property, plant and equipment. If all the criteria are not 
met, the production stripping costs are charged to the income statement as operating costs. The stripping activity 
asset is initially measured at cost, which is the accumulation of costs directly incurred to perform the stripping 
activity that improves access to the identified component of ore, plus an allocation of directly attributable overhead 
costs. If incidental operations are occurring at the same time as the production stripping activity, but are not 
necessary for the production stripping activity to continue as planned, these costs are not included in the cost of 
the stripping activity asset. If the costs of the stripping activity asset and the inventory produced are not separately 
identifiable, a relevant production measure is used to allocate the production stripping costs between the inventory 
produced and the stripping activity asset. The stripping activity asset is subsequently amortised over the expected 
useful life of the identified component of the orebody that became more accessible as a result of the stripping 
activity. Based on proven and probable reserves, the expected average stripping ratio over the average life of the 
area being mined is used to amortise the stripping activity. As a result, the stripping activity asset is carried at cost 
less amortisation and any impairment losses.

The average life of area cost per tonne is calculated as the total expected costs to be incurred to mine the orebody 
divided by the number of tonnes expected to be mined. The average life of area stripping ratio and the average life 
of area cost per tonne are recalculated annually in light of additional knowledge and changes in estimates. Changes 
in the stripping ratio are accounted for prospectively as a change in estimate.

Investment property
Investment property is initially recognised using the cost model. Subsequent recognition is at cost less accumulated 
depreciation, and less any accumulated impairment losses. Rental income from investment property is recognised 
on a straight-line basis over the term of the lease. Initial direct costs incurred in negotiating and arranging the lease 
are capitalised to investment property and depreciated over the lease term. Depreciation is calculated as follows:

Business combinations, goodwill and other intangible assets
Business combinations and goodwill 
Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as 
the aggregate of the consideration transferred, measured at acquisition date fair value and the amount of any 
non-controlling interest in the acquiree. The choice of measurement of non-controlling interest, either at fair value 
or at the proportionate share of the acquiree’s identifiable net assets, is determined on a transaction-by-transaction 
basis. Acquisition costs incurred are expensed and included in administrative expenses.

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate 
classification and designation in accordance with the contractual terms, economic circumstances and pertinent 
conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by 
the acquiree.

Any contingent consideration to be transferred by the acquirer will be recognised at fair value at the acquisition 
date. Subsequent changes to the fair value of the contingent consideration which is deemed to be an asset or 
liability will be recognised in accordance with IFRS 13 in the income statement. If the contingent consideration is 
classified as equity, it will not be remeasured until it is finally settled within equity.

Goodwill is initially measured at cost, being the excess of the aggregate of the acquisition date fair value of the 
consideration transferred and the amount recognised for the non-controlling interest (and where the business 
combination is achieved in stages, the acquisition date fair value of the acquirer’s previously held equity interest in 
the acquiree) over the net identifiable amounts of the assets acquired and the liabilities assumed in exchange for 
the business combination. Assets acquired and liabilities assumed in transactions separate to the business 
combinations, such as the settlement of pre-existing relationships or post-acquisition remuneration arrangements 
are accounted for separately from the business combination in accordance with their nature and applicable IFRS. 
Identifiable intangible assets, meeting either the contractual legal or separability criterion are recognised separately 
from goodwill. Contingent liabilities representing a present obligation are recognised if the acquisition date fair 
value can be measured reliably.

If the aggregate of the acquisition date fair value of the consideration transferred and the amount recognised for the 
non-controlling interest (and where the business combination is achieved in stages, the acquisition date fair value of 
the acquirer’s previously held equity interest in the acquiree) is lower than the fair value of the assets, liabilities and 
contingent liabilities, and the fair value of any pre-existing interest held in the business acquired, the difference is 
recognised in profit and loss.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of 
impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of 
the Group’s CGUs (or groups of CGUs) that are expected to benefit from the combination, irrespective of whether 
other assets or liabilities of the acquiree are assigned to those units. Each unit or group of units to which goodwill is 
allocated shall represent the lowest level within the entity at which the goodwill is monitored for internal 
management purposes, and shall not be larger than an operating segment before aggregation.

Where goodwill forms part of a CGU and part of the operation within that unit is disposed of, the goodwill 
associated with the operation disposed of is included in the carrying amount of the operation when determining 
the gain or loss on disposal of the operation. Goodwill disposed of in this circumstance is measured based on the 
relative values of the operation disposed of and the portion of the CGU retained.

Concessions and licences
Concessions and licences are shown at cost. Concessions and licences have a finite useful life and are carried at cost 
less accumulated amortisation and accumulated impairment losses. Amortisation is calculated using the straight-
line method to allocate the cost of concessions and licences over the shorter of the life of mine or term of the 
licence once production commences.

1.2.9 Other financial assets

Management determines the classification of its investments at initial recognition and re-evaluates this designation 
at every reporting date. Currently the Group only has financial assets at fair value through profit or loss, and loans 
and receivables.

When financial assets are recognised initially, they are measured at fair value plus (in the case of investments not at 
fair value through profit or loss) directly attributable costs.

Financial assets at fair value through profit or loss 
This category has two sub-categories: financial assets held for trading, and those designated at fair value through 
profit or loss. Upon initial recognition, a financial asset is classified in this category if acquired principally for the 
purpose of selling in the short term or if so designated by management. Derivatives are also categorised as held for 
trading unless they are designated as hedges. Gains and losses on investments held for trading are recognised in 
profit or loss. Assets in this category are classified as current assets if they are either held for trading or are expected 
to be realised within 12 months of the reporting date.

Loans and receivables 
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted 
in an active market. They are included in current assets, except those with maturities greater than 12 months after 
the reporting date. These are classified as non-current assets. Such assets are carried at amortised cost using the 
effective interest rate method, less any allowance for impairment, if the time value of money is significant. Gains and 
losses are recognised in the income statement when the loans and receivables are derecognised or impaired, as well 
as through the amortisation process. A provision for impairment of trade receivables is established when there is 
objective evidence that the Group will not be able to collect all amounts due according to the original terms of 
receivables. The amount of the provision is the difference between the asset’s carrying amount and the present 
value of estimated future cash flows, discounted at an appropriate interest rate. The amount of the provision is 
recognised in the income statement.

1.2.10 Financial liabilities

Interest-bearing borrowings 
Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated 
at amortised cost; any difference between proceeds (net of transaction costs) and the redemption value is 
recognised in the income statement, unless capitalised in accordance with Note 1.2.24, Finance costs, over the 
period of the borrowings, using the effective interest rate method.

Bank overdrafts are recognised at amortised cost.

Summary of significant accounting policies (continued)
1.2.11 Fair value measurement

The Group measures financial instruments at fair value at each reporting date. 

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction 
between market participants at the measurement date. The fair value measurement is based on the presumption 
that the transaction to sell the asset or transfer the liability takes place either:
 u in the principal market for the asset or liability; or
 u in the absence of a principal market, in the most advantageous market for the asset or liability.

The principal or the most advantageous market must be accessible by the Group.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when 
pricing the asset or liability, assuming that market participants act in their economic best interest.

A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate 
economic benefits by using the asset in its highest and best use or by selling it to another market participant that 
would use the asset in its highest and best use. 

The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are 
available to measure fair value, maximising the use of relevant observable inputs and minimising the use of 
unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorised 
within the fair value hierarchy, described as follows, based on the lowest-level input that is significant to the fair 
value measurement as a whole:

Level 1 – Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

Level 2 – Valuation techniques for which the lowest-level input that is significant to the fair value measurement is 
directly or indirectly observable.

Level 3 – Valuation techniques for which the lowest-level input that is significant to the fair value measurement is 
unobservable.

For assets and liabilities that are recognised in the financial statements on a recurring basis, the Group determines 
whether transfers have occurred between levels in the hierarchy by reassessing categorisation (based on the 
lowest-level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

1.2.12 Impairments

Non-financial assets 
Assets that are subject to amortisation or depreciation are reviewed for impairment if it is determined that there is 
an indication of impairment in accordance with IAS 36. Goodwill is assessed for impairment on an annual basis. An 
impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. 
The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. In assessing value in 
use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects 
current market assessments of the time value of money and the risks specific to the asset. Non-financial assets that 
were previously impaired are reviewed for possible reversal of the impairment at each reporting date.

A previously recognised impairment loss is reversed only if there has been a change in the estimates used to 
determine the asset’s recoverable amount since the last impairment loss was recognised. If that is the case, the 
carrying amount of the asset is increased to its recoverable amount. That increased amount cannot exceed the 
carrying amount that would have been determined, net of depreciation, had no impairment loss been recognised 
for the asset in prior years. Such a reversal is recognised in the income statement. After such a reversal the 
depreciation charge is adjusted in future periods to allocate the asset’s revised carrying amount, less any residual 
value, on a systematic basis over its remaining useful life.

Summary of significant accounting policies (continued)
1.2.12 Impairments (continued)
Financial assets 
The Group assesses at each reporting date whether a financial asset or group of financial assets is impaired.

Assets carried at amortised cost 
If there is objective evidence that an impairment loss on assets carried at amortised cost has been incurred, the 
amount of the loss is measured as the difference between the asset’s carrying amount and the present value of 
estimated future cash flows (excluding future expected credit losses that have not been incurred) discounted at the 
financial asset’s original effective interest rate (ie the effective interest rate computed at initial recognition). The 
carrying amount of the asset is reduced through the use of an allowance account. The amount of the loss is 
recognised in the income statement.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively 
to an event occurring after the impairment was recognised, the previously recognised impairment loss is reversed, 
to the extent that the carrying value of the asset does not exceed its amortised cost at the reversal date, any 
subsequent reversal of an impairment loss is recognised in the income statement.

In relation to trade receivables, a provision for impairment is made when there is objective evidence (such as the 
probability of insolvency or significant financial difficulties of the debtor) that the Group will not be able to collect all 
of the amounts due under the original terms of the invoice. The carrying amount of the receivable is reduced 
through the use of an allowance account. Impaired debts are derecognised when they are assessed as uncollectible.

1.2.13 Inventories

Inventories, which include rough diamonds, ore stockpiles and consumables, are measured at the lower of cost and 
net realisable value. The amount of any write-down of inventories to net realisable value and all losses, is recognised 
in the period the write-down or loss occurs. Cost is determined as the average cost of production, using the 
weighted average method. Cost includes directly attributable mining overheads, but excludes borrowing costs.

Net realisable value is the estimated selling price in the ordinary course of business, less the estimated costs of 
completion and the estimated costs to be incurred in marketing, selling and distribution.

1.2.14 Cash and cash equivalents

Cash and cash equivalents are carried in the statement of financial position at amortised cost. Cash and cash 
equivalents comprise cash on hand, deposits held at call with banks, and other short-term, highly liquid investments 
with original maturities of three months or less.

For the purpose of the cash flow statement, cash and cash equivalents consist of cash and cash equivalents as 
defined above, net of outstanding bank overdrafts.

1.2.15 Issued share capital

Ordinary shares are classified as equity. 

Incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction from 
the proceeds.

1.2.16 Foreign currency translations
Presentation currency 
The results and financial position of the Group’s subsidiaries which have a functional currency different from the 
presentation currency are translated into the presentation currency as follows:
 u statement of financial position items are translated at the closing rate at the reporting date;
 u income and expenses for each income statement are translated at average exchange rates (unless this average is 
not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which 
case income and expenses are translated at the dates of the transactions); and
 u resulting exchange differences are recognised as a separate component of equity.

Details of the rates applied at the respective reporting dates and for the income statement transactions are detailed 
in Note 16, Issued capital and reserves.

1.2.16 Foreign currency translations (continued)

Transactions and balances 
Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the 
dates of the transactions. Foreign exchange gains or losses resulting from the settlement of such transactions and 
from the translation at the period-end exchange rates of monetary assets and liabilities denominated in foreign 
currencies are recognised in the income statement. Non-monetary items that are measured in terms of cost in a 
foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary 
items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair 
value was determined. Monetary items for each statement of financial position presented are translated at the 
closing rate at the reporting date.

1.2.17 Share-based payments

Employees (including Senior Executives) of the Group receive remuneration in the form of share-based payment 
transactions, whereby employees render services as consideration for equity instruments (equity-settled 
transactions). In situations where some or all of the goods or services received by the entity as consideration for 
equity instruments cannot be specifically identified, they are measured as the difference between the fair value of 
the share-based payment and the fair value of any identifiable goods or services received at the grant date. For 
cash-settled transactions, the liability is remeasured at each reporting date until settlement, with the changes in fair 
value recognised in the income statement.

Equity-settled transactions 
The cost of equity-settled transactions with employees is measured by reference to the fair value at the date at 
which they are granted, and is recognised as an expense over the vesting period, which ends on the date on which 
the relevant employees become fully entitled to the award. Fair value is determined using an appropriate pricing 
model. In valuing equity-settled transactions, no account is taken of any vesting conditions, other than conditions 
linked to the price of the shares of the Company (market conditions).

No expense is recognised for awards that do not ultimately vest, except for awards where vesting is conditional 
upon a market condition, which are treated as vesting irrespective of whether or not the market condition is 
satisfied, provided that all other performance conditions are satisfied.

At each reporting date before vesting, the cumulative expense is calculated, representing the extent to which the 
vesting period has expired and management’s best estimate of the achievement or otherwise of non-market 
conditions and of the number of equity instruments that will ultimately vest or, in the case of an instrument subject 
to a market condition, be treated as vesting as described above. The movement in cumulative expense since the 
previous reporting date is recognised in the income statement, with a corresponding entry in equity.

Where the terms of an equity-settled award are modified or a new award is designated as replacing a cancelled or 
settled award, the cost based on the original award terms continues to be recognised over the original vesting 
period. In addition, an expense is recognised over the remainder of the new vesting period for the incremental fair 
value of any modification, based on the difference between the fair value of the original award and the fair value of 
the modified award, both as measured on the date of the modification. No reduction is recognised if this difference 
is negative.

Where an equity-settled award is cancelled, it is treated as if it had vested on the date of cancellation, and any cost 
not yet recognised in the income statement for the award is expensed immediately. 

Where an equity-settled award is forfeited, it is treated as if vesting conditions had not been met and all costs 
previously recognised in the income statement for the award are reversed and recognised in income immediately.

Management applies judgement when determining whether share options relating to employees who resigned 
before the end of the service condition period are cancelled or forfeited as referred under policy 1.2.26, Critical 
accounting estimates and judgements.

1.2.18 Provisions

Provisions are recognised when:
 u the Group has a present legal or constructive obligation as a result of a past event; and
 u a reliable estimate can be made of the obligation.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation, 
using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the 
obligation. The increase in the provision due to the passage of time is recognised as a finance cost.

1.2.19 Restoration and rehabilitation

The mining, extraction and processing activities of the Group normally give rise to obligations for site restoration 
and rehabilitation. Rehabilitation works can include facility decommissioning and dismantling, removal and 
treatment of waste materials, land rehabilitation, and site restoration. The extent of the work required and the 
estimated cost of final rehabilitation, comprising liabilities for decommissioning and restoration, are based on 
current legal requirements, existing technology and the Group’s environmental policies, and is reassessed annually. 
Cost estimates are not reduced by the potential proceeds from the sale of property, plant and equipment.

Provisions for the cost of each restoration and rehabilitation programme are recognised at the time the 
environmental disturbance occurs. When the extent of the disturbance increases over the life of the operation, the 
provision and associated asset is increased accordingly. Costs included in the provision encompass all restoration 
and rehabilitation activity expected to occur. The restoration and rehabilitation provisions are measured at the 
expected value of future cash flows, discounted to their present value. Discount rates used are specific to the 
country in which the operation is located. The value of the provision is progressively increased over time as the 
effect of the discounting unwinds, which is recognised in finance charges. Restoration and rehabilitation provisions 
are also adjusted for changes in estimates.

When provisions for restoration and rehabilitation are initially recognised, the corresponding cost is capitalised as an 
asset where it gives rise to a future benefit and depreciated over future production from the operation to which it 
relates.

1.2.20 Taxation

Income tax for the period comprises current and deferred tax. Income tax is recognised in the income statement 
except to the extent that it relates to items charged or credited directly to equity, in which case it is recognised in 
equity. Current tax expense is the expected tax payable on the taxable income for the period, using tax rates 
enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous 
years.

Deferred tax is provided using the statement of financial position liability method, providing for temporary 
differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts 
used for taxation purposes.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the 
asset is realised or the liability is settled based on the tax rates (and tax laws) that have been enacted or substantively 
enacted at the reporting date.

A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available 
against which the asset can be utilised. Deferred tax assets are reduced to the extent that it is no longer probable 
that the related tax benefit will be realised.

In respect of taxable temporary differences associated with investments in subsidiaries, associates and jointly 
controlled entities, deferred tax is provided except where the timing of the reversal of the temporary differences can 
be controlled by the Group and it is probable that the temporary differences will not reverse in the foreseeable 
future.

In respect of deductible temporary differences associated with investments in subsidiaries, associates and jointly 
controlled entities, deferred tax assets are only recognised to the extent that it is probable that the temporary 
differences will reverse in the foreseeable future and taxable profit will be available against which the temporary 
differences can be utilised.

Withholding tax is recognised in the income statement when dividends or other services which give rise to that 
withholding tax are declared or accrued respectively. Withholding tax is disclosed as part of current tax. 

Royalties 
Royalties incurred by the Group comprise mineral extraction costs based on a percentage of sales paid to the local 
revenue authorities. These obligations arising from royalty arrangements are recognised as current payables and 
disclosed as part of royalty and selling costs in the income statement.

Royalties and revenue-based taxes are accounted for under IAS 12 when they have the characteristics of an income 
tax. This is considered to be the case when they are imposed under government authority and the amount payable 
is based on taxable income – rather than based on quantity produced or as a percentage of revenue. For such 
arrangements, current and deferred tax is provided on the same basis as described above for other forms of taxation. 
The royalties incurred by the Group are considered not to meet the criteria to be treated as part of income tax.

1.2.21 Employee benefits

Provision is made in the financial statements for all short-term employee benefits. Liabilities for wages and salaries, 
including non-monetary benefits, benefits required by legislation, annual leave, retirement benefits and 
accumulating sick leave obliged to be settled within 12 months of the reporting date, are recognised in trade and 
other payables and are measured at the amounts expected to be paid when the liabilities are settled. Benefits falling 
due more than 12 months after the reporting date are discounted to present value. The Group recognises an 
expense for contributions to the defined contribution pension fund in the period in which the employees render 
the related service.

Bonus plans 
The Group recognises a liability and an expense for bonuses. The Group recognises a liability where contractually 
obliged or where there is a past practice that has created a constructive obligation. These liabilities are recognised in 
trade and other payables and are measured at the amounts expected to be paid when the liabilities are settled.

1.2.22 Leases

The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement 
at inception date of whether the fulfilment of the arrangement is dependent on the use of a specific asset or assets 
or the arrangement conveys a right to use the asset. A reassessment is made after inception of the lease only if one 
of the following applies:
(a)  there is a change in contractual terms, other than a renewal or extension of the arrangement;
(b)   a renewal option is exercised or extension granted, unless the term of the renewal or extension was initially 

included in the lease term;

(c)  there is a change in the determination of whether fulfilment is dependent on a specific asset; or
(d)  there is a substantial change to the asset.

Where a reassessment is made, lease accounting shall commence or cease from the date when the change in 
circumstances gave rise to the reassessment for scenarios (a), (c) or (d) and at the date of renewal or extension 
period for scenario (b).

Group as a lessee 
Leases of property, plant and equipment where the Group has, substantially, all the risks and rewards of ownership 
are classified as finance leases. Finance leases are capitalised at the lease’s inception at the lower of the fair value of 
the leased property and the present value of the minimum lease payments. Each lease payment is allocated 
between the liability and finance charges so as to achieve a constant rate on the finance balance outstanding. The 
corresponding lease obligations, net of finance charges, are included in financial liabilities.

The interest element of the finance cost is charged to the income statement over the lease period so as to produce 
a constant periodic rate of interest on the remaining balance of the liability for each year. The property, plant and 
equipment acquired under finance leases are depreciated over the shorter of the asset’s useful life and the lease 
term.

Leases where the lessor retains substantially all the risks and rewards of ownership are classified as operating leases. 
Payments made under operating leases (net of any incentives received from the lessor) are charged to the income 
statement on a straight-line basis over the period of the lease. When the Group is a party to a lease where there is a 
contingent rental element associated within the agreement, a cost is recognised as and when the contingency 
materialises.

Group as a lessor 
Assets leased out under operating leases are included in investment property. Rental income is recognised on a 
straight-line basis over the lease term. Refer to Note 1.2.7, Investment property, for further information on the 
treatment of investment property.

1.2.23 Revenue

Revenue is measured at fair value of the consideration received or receivable and comprises the fair value for the 
sale of goods, net of value added tax, rebates and discounts and after eliminated sales within the Group. Revenue is 
recognised as follows:

Sale of goods 
Revenue is recognised when the significant risks and rewards of ownership have been transferred to the customer 
and can be measured reliably and receipt of future economic benefits is probable.

The following revenue streams are recognised:
 u rough diamonds which are made through competitive tender processes, partnership agreements and joint 

operation arrangements;

 u polished diamonds and other products which are made through direct sale transactions;
 u additional uplift on partnership arrangements; and
 u additional uplift on joint operation arrangements.

Revenue through joint operation arrangements is recognised for the sale of the rough diamond according to the 
percentage interest in the joint operation arrangement, as only that percentage of significant risks and rewards pass 
at the time of sale. Contractual agreements are entered into between the Group and the joint operation partner 
(partner) whereby both parties control jointly the cutting and polishing activities relating to the diamond. All 
decisions pertaining to the cutting and polishing of the diamonds require unanimous consent from both parties. 
Once these activities are complete, the polished diamond is sold, after which the revenue on the remaining 
percentage of the rough diamond is recognised, together with additional uplift on the joint operation arrangement. 
For more detail on how these arrangements have been included in the financial statements refer to Note 2, 
Revenue. The Group portion of inventories related to these transactions is included in the total inventories balance 
refer to Note 14, Inventories.

Revenue through partnership arrangements is recognised for the sale of the rough diamond, with an additional 
uplift based on the polished margin achieved. Management recognises the revenue on the sale of the rough 
diamond when it is sold to a third party, as there is no continuing involvement by management in the cutting and 
polishing process and the significant risks and rewards have passed to the third party. For additional uplift on 
partnership arrangements, certain estimates and judgements are made by management as referred to under policy 
1.2.26, Critical accounting estimates and judgements.

Rendering of service 
Revenue from services relating to third-party diamond manufacturing is recognised in the accounting period in 
which the services are rendered, and it is probable that the economic benefits associated with the transaction will 
flow to the entity, by reference to completion of the specific transaction assessed on the basis of the actual service 
provided as a proportion of the total services to be provided.

Interest income 
Interest income is recognised on a time-proportion basis using the effective interest rate method.

Dividends 
Dividends are recognised when the amount of the dividend can be reliably measured and the Group’s right to 
receive payment is established.

1.2.24 Finance costs

Finance costs are generally expensed as incurred, except where they relate to the financing of construction or 
development of qualifying assets requiring a substantial period of time to prepare for their intended future use. 
Finance costs are capitalised up to the date when the asset is ready for its intended use.

1.2.25 Dividend distribution

Dividend distributions to the Group’s shareholders are recognised as a liability in the Group’s financial statements in 
the period in which the dividends are approved by the Group’s shareholders.

1.2.26 Critical accounting estimates and judgements

The preparation of the consolidated financial statements requires management to make estimates and judgements 
and form assumptions that affect the reported amounts of the assets and liabilities, the reported revenue and costs 
during the periods presented therein, and the disclosure of contingent liabilities at the date of the financial 
statements. Estimates and judgements are continually evaluated and are based on historical experience and other 
factors, including expectations of future events that are believed to be reasonable under the circumstances.

The Group makes estimates and assumptions concerning the future and the resulting accounting estimates will, by 
definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of 
causing a material adjustment to the financial results or the financial position reported in future periods are 
discussed below.

Estimates
Life of mine (LoM)
There are numerous uncertainties inherent in estimating ore reserves and the associated LoM. Therefore the Group 
must make a number of assumptions in making those estimations, including assumptions as to the prices of 
commodities, exchange rates, production costs and recovery rates. Assumptions that are valid at the time of 
estimation may change significantly when new information becomes available. Changes in the forecast prices of 
commodities, exchange rates, production costs or recovery rates may change the economic status of ore reserves 
and may, ultimately, result in the ore reserves being restated. Where assumptions change the LoM estimates, the 
associated depreciation rates, residual values, waste stripping and amortisation ratios, and environmental provisions 
are reassessed to take into account the revised LoM estimate. Refer to Note 9, Property, plant and equipment.

Exploration and evaluation expenditure
This policy requires management to make certain estimates and assumptions as to future events and circumstances, 
in particular whether economically viable extraction operations are viable where reserves have been discovered and 
whether indications of impairment exist. Any such estimates and assumptions may change as new information 
becomes available. Refer to Note 9, Property, plant and equipment.

Provision for restoration and rehabilitation
Significant estimates and assumptions are made in determining the amount of the restoration and rehabilitation 
provisions. These deal with uncertainties such as changes to the legal and regulatory framework, magnitude of 
possible contamination, and the timing, extent and costs of required restoration and rehabilitation activity. Refer to 
Note 19, Provisions, for further detail.

Judgements
Development expenditure
Judgement is applied by management in determining when a project has reached a stage at which economically 
recoverable reserves exist and that development may be sanctioned. Management is required to make certain 
estimates and assumptions similar to those described above for capitalised exploration and evaluation expenditure. 
Refer to Note 9, Property, plant and equipment.

Revenue – partnership arrangements
Management has entered into partnership arrangements to increase the revenue earned on the sale of rough
diamonds. Under these arrangements, revenue is earned for the sale of the rough diamond, with an additional uplift 
based on the polished margin achieved. Management recognises the revenue on the sale of the rough diamond at 
the point at which it is sold to the third party, as there is no continuing involvement by management in the cutting 
and polishing process and the significant risks and rewards have passed to the third party. Judgement is applied by 
management in determining when additional uplift is recognised and measured with regard to rough diamonds 
sold into partnership arrangements. Management is required to make certain estimates and assumptions based on 
when the uplift can be reliably measured. This occurs when the third party sells these goods, at which point the 
value of the final polished goods are determined.

Summary of significant accounting policies (continued)
1.2.26 Critical accounting estimates and judgements (continued)

Impairment reviews
The Group determines if goodwill is impaired at least on an annual basis, while all other significant operations are 
tested for impairment when there are potential indicators which may require impairment review. This requires an 
estimation of the recoverable amount of the relevant cash-generating unit under review. Recoverable amount is the 
higher of fair value less costs to sell and value in use.

While conducting an impairment review of its assets using value-in-use impairment models, the Group exercises 
judgement in making assumptions about future rough diamond prices, exchange rates, volumes of production, ore 
reserves and resources included in the current LoM plans, production costs and macro-economic factors such as 
inflation and discount rates. Changes in estimates used can result in significant changes to the consolidated income 
statement and consolidated statement of financial position.

The results of the impairment testing performed indicated an impairment on the Ghaghoo mining operation as 
disclosed in Note 12, Impairment testing.

The key assumptions used in the recoverable amount calculations, determined on a value-in-use basis, are listed in 
the table below:

Valuation basis
Discounted present value of future cash flows.

LoM and recoverable value of reserves and resources
Economically recoverable reserves and resources, carats recoverable and grades achievable are based on 
management’s expectations of the availability of reserves and resources at mine sites and technical studies 
undertaken by in-house and third-party specialists. Reserves remaining after the current LoM plans and current lease 
periods have not been included in determining the value in use of the operations.

Capital expenditure
Management has estimated the timing and quantum of the capital expenditure based on the Group’s current LoM 
plans for each operation.

Diamond prices
The diamond prices used in the impairment test have been set with reference to recent prices achieved, the Group’s 
medium-term forecast and market trends. Long-term diamond price escalation reflects the Group’s assessment of 
market supply/demand fundamentals.

Discount rate
The discount rate of 12.6% (2015: 12.0%)used for Letšeng and 12.0% (2015: 13.1%) for Ghaghoo, in both instances 
represents the before-tax risk-free rate adjusted for market risk, volatility and risks specific to the asset and its 
operating jurisdiction.

Cost and inflation rate
These costs for Letšeng are determined on management’s experience and the use of contractors over a period of 
time whose costs are fairly reasonably determinable. Mining costs have been based on the negotiated eight-year 
mining contract, which came into effect from 1 January 2014. Costs of extracting and processing which are 
reasonably determinable are based on management’s experience. Long-term inflation rates of 4% to 6% above the 
long-term US dollar inflation rate were used for operating costs and capital cost escalators.

Exchange rates
Exchange rates are estimated based on an assessment at current market fundamentals and long-term expectations. 
The US$/Lesotho Loti (LSL) and US$/Botswana Pula (BWP) exchange rate used was determined with reference to the 
closing rate at 31 December 2016 of LSL13.68 and BWP10.68, respectively.

Sensitivity
The value in use for Letšeng indicated sufficient headroom, and no reasonable change in the key assumptions will 
result in an impairment.

Summary of significant accounting policies (continued)
1.2.26 Critical accounting estimates and judgements (continued)

Market capitalisation
The Group has made a judgement in determining if, in the instance where the Group’s asset carrying values exceed 
market capitalisation, this results in an indicator of impairment. All significant operations were assessed for 
impairment during the year and impairments were recognised where relevant.

Refer to Note 12, Impairment testing, for further detail.

Capitalised stripping costs (deferred waste)
Waste removal costs (stripping costs) are incurred during the development and production phases at surface 
mining operations. Furthermore, during the production phase, stripping costs are incurred in the production of 
inventory as well as in the creation of future benefits by improving access and mining flexibility in respect of the ore 
to be mined, the latter being referred to as a ‘stripping activity asset’. Judgement is required to distinguish between 
these two activities at Letšeng. The orebody needs to be identified in its various separately identifiable components. 
An identifiable component is a specific volume of the orebody that is made more accessible by the stripping 
activity. Judgement is required to identify and define these components (referred to as ‘cuts’), and also to determine 
the expected volumes (tonnes) of waste to be stripped and ore to be mined in each of these components. These 
assessments are based on a combination of information available in the mine plans, specific characteristics of the 
orebody and the milestones relating to major capital investment decisions.

Judgement is also required to identify a suitable production measure that can be applied in the calculation and 
allocation of production stripping costs between inventory and the stripping activity asset. The ratio of expected 
volume (tonnes) of waste to be stripped for an expected volume (tonnes) of ore to be mined for a specific 
component of the orebody, compared to the current period ratio of actual volume (tonnes) of waste to the volume 
(tonnes) of ore is considered to determine the most suitable production measure.

These judgements and estimates are used to calculate and allocate the production stripping costs to inventory and/
or the stripping activity asset(s). Furthermore, judgements and estimates are also used to apply the stripping ratio 
calculation in determining the amortisation of the stripping activity asset. Refer to Note 9, Property, plant and 
equipment, for further detail.

Stripping ratio
Estimated recoverable reserves are used in determining the amortisation of mine-specific assets. Amortisation is 
calculated by using the expected average stripping ratio over the average life of the area being mined. The average 
stripping ratio is calculated as the number of tonnes of waste material expected to be removed during the life of 
area, per tonne of ore mined. The average life of area cost per tonne is calculated as the total expected costs to be 
incurred to mine the orebody divided by the number of tonnes expected to be mined. The average life of area 
stripping ratio and the average life of area cost per tonne are recalculated annually in light of additional knowledge 
and changes in estimates. Changes in the stripping ratio are accounted for prospectively as a change in estimate. 
Refer to Note 9, Property, plant and equipment, for further detail.

Production start date
The phase of each mine construction project is assessed to determine when a mine moves into the production 
phase. The criteria used to assess the start date are determined by the unique nature of each mine’s construction 
project and include factors such as the complexity of a plant and its location. Various relevant criteria are considered 
to assess when the mine is substantially complete and ready for its intended use and moves into the production 
phase. At this point, all related amounts are reclassified from ‘exploration and development assets’ to ‘mining assets’, 
‘stripping activity asset’ and/or ‘property, plant and equipment’. Some of the criteria would include but are not 
limited to the following:
 u the level of capital expenditure compared to the construction costs estimates;
 u completion of a reasonable period of testing of the mine plant and equipment;
 u ability to produce inventory in saleable form; and
 u ability to sustain ongoing production of inventory.

Refer to Note 9, Property, plant and equipment, for further detail.

NOTES TO THE FINANCIAL STATEMENTS (continued)
1.2

Summary of significant accounting policies (continued)
1.2.26 Critical accounting estimates and judgements (continued)

Production start date (continued)
When a mine construction project moves into the production phase, the capitalisation of certain mine construction 
costs ceases and costs are either regarded as inventory or expensed, except for capitalisable costs related to mining 
asset additions or improvements, production phase stripping costs capitalisable as stripping activity asset(s), and 
exploration expenditure that meets the criteria for capitalisation. It is also at this point that depreciation/
amortisation commences.

Management made the key judgement that the Ghaghoo mine had not reached production start date during the 
year based on the following:
 u Continued operational and technical challenges as a result of difficult ground conditions resulted in Ghaghoo 

not achieving its planned ramp-up profile and production targets.

 u Inconsistent plant throughput rates impacting ability to sustain ongoing production of inventory.

As a result, the mine was not in the condition necessary for it to be capable of operating in the manner intended by 
management on a sustainable basis and therefore the mine remained in its construction phase with all costs 
incurred during the year being capitalised to the exploration and development asset. Subsequent to period end, the 
Ghaghoo mine was placed on care and maintenance and all costs previously capitalised to the exploration and 
development asset were impaired in full as disclosed in Note 9, Property, plant and equipment.

Share-based payments
Judgement is applied by management in determining whether the share options relating to employees who 
resigned before the end of the service condition period have been cancelled or forfeited in light of their leaving 
status. Where employees do not meet the requirements of a good leaver as per the rules of the long-term incentive 
plan (LTIP), no award will vest and this will be treated as cancellation by forfeiture. The expenses relating to these 
charges previously recognised are then reversed. Where employees do meet the requirements of a good leaver as 
per the rules of the LTIP, some or all of an award will vest and this will be treated as a modification to the original 
award. The future expenses relating to these awards are accelerated and recognised as an expense immediately. 
Refer to Note 25, Share-based payments, for further detail. 

1.2.27 Exceptional items

The Group presents as exceptional items on the face of the income statement, those material items of income and 
expenses which, because of the nature and expected infrequency of the events giving rise to them, merit separate 
presentation to allow shareholders to understand better the elements of financial performance in the year, so as to 
facilitate comparison with prior periods and to assess better trends in financial performance. Refer to Note 4, 
Exceptional items, for further detail.

1  As a result of the continued market uncertainty, the ongoing difficult market conditions for Ghaghoo’s production and the 
challenges in the operation reaching targeted production it was decided to place the mine on care and maintenance post-year 
end. Ghaghoo’s recoverable amount was reassessed at 31 December 2016 and an impairment was considered appropriate. The 
Group recognised a consolidated income statement impairment charge of US$170.8 million (post-tax), being the write-down of 
US$0.2 million inventory and all non-current assets of Ghaghoo.
2   During 2016, the Group abandoned the CDIH Group, which developed and maintained laser diamond shaping and cutting 

technology and machinery due to its inability to generate profits. The impairment on CDIH includes US$0.3 million write-down of 
inventory and US$1.9 million write-down of other assets. 

Goodwill
Goodwill acquired through business combinations has been allocated to the individual

Movement in goodwill relates mainly to foreign exchange translation from functional to presentation currency.

The discount rate is outlined below, and represents the nominal pre-tax rate. This rate is based on the weighted average cost of 
capital (WACC) of the Group and adjusted accordingly at a risk premium for the Letšeng Diamonds cash-generating unit, taking 
into account risks associated therein.

Goodwill impairment testing is undertaken annually and whenever there are indications of impairment. The most recent test was 
undertaken at 31 December 2016. In assessing whether goodwill has been impaired, the carrying amount of the Letšeng Diamonds 
cash-generating unit is compared with its recoverable amount. For the purpose of goodwill impairment testing in 2016, the 
recoverable amount for Letšeng Diamonds has been determined based on a value-in-use model, similar to that done in the past.

Value in use
Cash flows are projected for a period up to the date that mining is expected to cease, based on management’s expectations at the 
time of completing the testing. The period used was eight years, representing the lesser of the current economic resource or the 
remaining eight-year mining lease period.

IMPAIRMENT TESTING (continued)

Sensitivity to changes in assumptions
For the purpose of testing for impairment of goodwill using the value-in-use basis for the Letšeng mining cash-generating unit, it 
was assessed that no reasonably possible change in any of the key assumptions would cause its carrying amount to exceed its 
recoverable amount.

The Group will continue to test its assets for impairment where indications are identified and may, in future, record additional 
impairment charges or reverse any impairment charges to the extent that market conditions improve and to the extent permitted 
by accounting standards.

   This loan is a three-year unsecured project debt facility signed jointly with Standard Lesotho Bank and Nedbank Limited on 26 June 2014 for the total 
funding of the Coarse Recovery Plant. The loan is repayable in 10 quarterly payments which commenced 31 March 2015 with a final payment due on 30 
June 2017; however, full repayment was made on 10 February 2017. The interest rate for the facility at 31 December 2016 is 12.3% (31 December 2015:

2  US$25.0 million bank loan facility at Gem Diamonds Botswana (Ghaghoo)
   Following the decision to place the Ghaghoo mine on care and maintenance, the US$25.0 million facility was repaid through the utilisation of the existing 
Company US$35.0 million facility. At 31 December 2016, the facility was reclassified into current liabilities.

   Total interest for the year on the interest-bearing loans and borrowings was US$1.9 million (2015: US$2.5 million) of which US$1.6 million related to the 
Ghaghoo facility and has been capitalised to the carrying value of the asset as borrowing costs. 

Other facilities
In addition, at 31 December 2016, the Group has the following available facilities:
 u At Gem Diamonds Limited, a US$35.0 million three-year unsecured revolving credit facility with Nedbank Capital which was

Rehabilitation provisions
The provisions have been recognised as the Group has an obligation for rehabilitation of the mining areas. The provisions have 
been calculated based on total estimated rehabilitation costs, discounted back to their present values over the life of mine at the 
mining operations. The pre-tax discount rates are adjusted annually and reflect current market assessments. 

In determining the amounts attributable to the rehabilitation provisions, management used a discount rate range of 6.0% to 7.4% 
(31 December 2015: 6.5% to 7.5%), estimated rehabilitation timing of eight to 11 years (31 December 2015: nine to 12 years) and an 
inflation rate range of 4.0% to 6.7% (31 December 2015: 4.6% to 6.0%) respectively at the Botswana and Lesotho mining areas. In 
addition to the changes in the discount rates, inflation and rehabilitation timing, the increase in the provision is attributable to the 
annual reassessment of the estimated closure costs performed at the operations and the strengthening of the local currencies 
against the US dollar.

The Group has not recognised a deferred tax liability for all taxable temporary differences associated with investments in 
subsidiaries because it is able to control the timing of dividends and only part of the temporary difference is expected to reverse in 
the foreseeable future. The gross temporary difference in respect of the undistributable reserves of the Group’s subsidiaries for 
which a deferred tax liability has not been recognised is US$49.3 million (31 December 2015: US$39.1 million).

The Group has estimated tax losses of US$348.3 million (31 December 2015: US$311.7 million). The deferred tax asset of 
US$0.9 million recognised in the prior year has been fully utilised during the current year. All tax losses are generated in jurisdictions 
where tax losses do not expire.

COMMITMENTS AND CONTINGENCIES 

Commitments
Operating lease commitments – Group as lessee
The Group has entered into commercial lease arrangements for rental of office premises. These 
leases have a period of between two and 12 years with an option of renewal at the end of the 
period. The terms will be negotiated during the extension option periods catered for in the 
agreements. There are no restrictions placed upon the lessee by entering into these leases.
Future minimum rentals payable under non-cancellable operating leases:
– Within one year
– After one year but not more than five years
– More than five years

Mining leases
Mining lease commitments represent the Group’s future obligation arising from agreements 
entered into with local authorities in the mining areas that the Group operates.

The period of these commitments is determined as the lesser of the term of the agreement, 
including renewable periods, or the life of the mine. The estimated lease obligation regarding 
the future lease period, accepting stable inflation and exchange rates, is as follows:
– Within one year
– After one year but not more than five years
– More than five years

Moveable equipment lease
The Group has entered into commercial lease arrangements which include the provision of 
loading, hauling and other transportation services payable at a fixed rate per tonne of ore and 
waste mined; power generator equipment payable based on a consumption basis; and rental 
agreements for various mining equipment based on a fixed monthly fee.
– Within one year
– After one year but not more than five years

The main capital expenditure approved but not contracted for relates to the construction of the Letšeng mining workshop of 
LSL215.0 million (US$15.7 million). The capital expenditure will be funded from a new project facility which is being finalised 
in 2017.

Contingent rentals – Alluvial Ventures
The contingent rentals represent the Group’s obligation to a third party (Alluvial Ventures) for operating a third plant on the Group’s 
mining property at Letšeng Diamonds. The rental is determined when the actual diamonds mined by Alluvial Ventures are sold. The 
rental agreement is based on 50% to 70% of the value (after costs) of the diamonds recovered by Alluvial Ventures and is limited to 
US$1.2 million per individual diamond. As at the reporting date, such future sales cannot be determined.

Letšeng Diamonds Educational Fund
In terms of the mining agreement entered into between the Group and the government of the Kingdom of Lesotho, the Group has 
an obligation to provide funding for education and training scholarships. The quantum of such funding is at the discretion of the 
Letšeng Diamonds Education Fund Committee. The amount of the funding provided for the current year was US$0.1 million 
(31 December 2015: US$0.1 million).

COMMITMENTS AND CONTINGENCIES (continued)

Contingencies
The Group has conducted its operations in the ordinary course of business in accordance with its understanding and interpretation 
of commercial arrangements and applicable legislation in the countries where the Group has operations. In certain specific 
transactions, however, the relevant third party or authorities could have a different interpretation of those laws and regulations that 
could lead to contingencies or additional liabilities for the Group. Having consulted professional advisers, the Group has identified 
possible disputes approximating US$0.5 million (December 2015: US$0.6 million) and tax claims within the various jurisdictions in 
which the Group operates approximating US$1.0 million (December 2015: US$1.3 million). There are no possible disputes relating 
to Ghaghoo’s care and maintenance status included in these contingencies.

There remains a risk that further tax liabilities may potentially arise. While it is difficult to predict the ultimate outcome in some 
cases, the Group does not anticipate that there will be any material impact on the Group’s results, financial position or liquidity.

24. 

FINANCIAL RISK MANAGEMENT
Financial risk factors
The Group’s activities expose it to a variety of financial risks:
 u market risk (including commodity price risk and foreign exchange risk);
 u credit risk; and
 u liquidity risk.

The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise 
potential adverse effects on the Group’s financial performance.

Risk management is carried out under policies approved by the Board of Directors. The Board provides principles for overall risk 
management, as well as policies covering specific areas, such as foreign exchange risk, interest rate risk, credit risk, use of derivative 
financial instruments and non-derivative financial instruments, and investing excess liquidity.

There have been no changes to the financial risk management policy since the prior year.

Capital management
The capital of the Company is the issued share capital, share premium and treasury shares on the Group’s statement of financial 
position. The primary objective of the Group’s capital management is to ensure that it maintains a strong credit rating and healthy 
capital ratios in order to support its business and maximise shareholder value. The Group manages its capital structure and makes 
adjustments to it, in light of changes in economic conditions. To maintain or adjust the capital structure, the Group may issue new 
shares. The management of the Group’s capital is performed by the Board. 

At 31 December 2016, the Group has US$53.3 million (31 December 2015: US$16.1 million) debt facilities available and continues to 
have the flexibility to manage the capital structure more efficiently by the use of these debt facilities, thus ensuring that an 
appropriate gearing ratio is achieved.

The debt facilities in the Group are as follows:

Unsecured – Standard Lesotho Bank and Nedbank Capital (a division of Nedbank Limited) – three-year unsecured revolving 
credit facility – LSL250.0 million (US$18.3 million)
The Group, through its subsidiary, Letšeng Diamonds, has an LSL250.0 million (US$18.3 million), three-year unsecured revolving 
working capital facility. The facility bears interest at the Lesotho prime rate. 

At year end, there is no drawdown on this facility.

Secured – Nedbank Capital (a division of Nedbank Limited) – six-and-a-half-year project debt facility – US$25.0 million
The Group, through its subsidiary, Gem Diamonds Botswana (Ghaghoo), has a secured debt loan facility held with Nedbank Capital. 
In November 2016 this loan was restructured in order to postpone further capital repayments from June 2016 to June 2019, with 
final repayment due on 31 December 2021. The loan is repayable in staggered bi-annual payments. The first capital repayment of 
US$0.1 million was paid in June 2016 with the next capital repayment due in June 2019. The facility bears interest at London USD 
Interbank three-month LIBOR + 5.5%.

At year end, this facility was fully drawn down. Post-year end this facility was fully repaid in line with placing the Ghaghoo asset 
on care and maintenance. For further detail refer to Note 17, Interest-bearing borrowings and Note 29, Events after the 
reporting period.

Unsecured – Standard Lesotho Bank and Nedbank Limited – three-year unsecured project debt facility – LSL140.0 million 
(US$10.2 million)
This loan is a three-year unsecured project debt facility signed jointly with Standard Lesotho Bank and Nedbank Limited on 26 June 
2014 for LSL140.0 million, being the total funding of the Coarse Recovery Plant with a final payment due on 30 June 2017. This 
facility bears interest at South African JIBAR + 4.95%.

At year end, there was LSL28.0 million (US$2.0 million) outstanding on this facility. Post-year end, this facility was fully repaid in 
advance of its final repayment date. For further detail refer to Note 17, Interest-bearing borrowings and Note 29, Events after the 
reporting period.

Unsecured – Nedbank Capital (a division of Nedbank Limited) – three-year unsecured revolving credit facility – US$35.0 million
The Company has a US$35.0 million three-year unsecured revolving credit facility with Nedbank Capital which was renewed on 
29 January 2016. This facility bears interest at London USD Interbank three-month LIBOR + 5.5%. 

At year end, there is no drawdown on this facility. Post-year end this facility was accessed in order to settle the Ghaghoo 
US$25.0 million facility.

FINANCIAL RISK MANAGEMENT (continued)
Capital management (continued)
The Group is subject to diamond price risk. Diamonds are not homogeneous products and the price of rough diamonds is not 
monitored on a public index system. The fluctuation of prices is related to certain features of diamonds such as quality and size. 
Diamond prices are marketed in US dollar and long-term US$ per carat prices are based on external market consensus forecasts 
and contracted sales arrangements adjusted for the Group’s specific operations. The Group does not have any financial instruments 
that may fluctuate as a result of commodity price movements.

(a)

Market risk
(i)

Foreign exchange risk
The Group operates internationally and is exposed to foreign exchange risk arising from various currency exposures, 
primarily with respect to the Lesotho Loti, South African Rand and Botswana Pula. Foreign exchange risk arises when 
future commercial transactions, recognised assets and liabilities are denominated in a currency that is not the entity’s 
functional currency.

The Group’s sales are denominated in US dollar which is the functional currency of the Company, but not the 
functional currency of the operations.

The currency sensitivity analysis below is based on the following assumptions:

Differences resulting from the translation of the financial statements of the subsidiaries into the Group’s presentation 
currency of US dollar, are not taken into consideration.

The major currency exposures for the Group relate to the US dollar and local currencies of subsidiaries. Foreign 
currency exposures between two currencies where one is not the US dollar are deemed insignificant to the Group 
and have therefore been excluded from the sensitivity analysis.

The analysis of the currency risk arises because of financial instruments denominated in a currency that is not the 
functional currency of the relevant Group entity. The sensitivity has been based on financial assets and liabilities at 
31 December 2016. There has been no change in the assumptions or method applied from the prior year.

(ii)

(iii)

Sensitivity analysis
If the US dollar had appreciated/(depreciated) 10% against currencies significant to the Group at 31 December 2016, 
income before taxation would have been US$2.6 million higher/(lower) (31 December 2015: US$3.1 million). There 
would be no effect on equity reserves other than those directly related to income statement movements.

Forward exchange contracts
The Group enters into forward exchange contracts to hedge the exposure to changes in foreign currency of future 
sales of diamonds at Letšeng Diamonds. The Group performs no hedge accounting. At 31 December 2016, the 
Group had no forward exchange contracts outstanding (31 December 2015: US$nil).

Cash flow interest rate risk
The Group’s income and operating cash flows are substantially independent of changes in market interest rates. The 
Group’s cash flow interest rate risk arises from borrowings. Borrowings issued at variable rates expose the Group to 
cash flow interest rate risk. At the time of taking new loans or borrowings, management uses its judgement to decide 
whether it believes that a fixed or variable rate borrowing would be more favourable to the Group over the expected 
period until maturity.

(b)

Credit risk
The Group’s potential concentration of credit risk consists mainly of cash deposits with banks and other receivables. The 
Group’s short-term cash surpluses are placed with the banks that have investment grade ratings. The maximum credit risk 
exposure relating to financial assets is represented by the carrying value as at the reporting dates. The Group considers the 
credit standing of counterparties when making deposits to manage the credit risk.

Considering the nature of the Group’s ultimate customers and the relevant terms and conditions entered into with such 
customers, the Group believes that credit risk is limited as customers pay on receipt of goods.

No other financial assets are impaired or past due and accordingly, no additional analysis has been provided. 

No collateral is held in respect of any impaired receivables or receivables that are past due but not impaired.

FINANCIAL RISK MANAGEMENT (continued)
Capital management (continued)
(c)

Liquidity risk
Liquidity risk arises from the Group’s inability to obtain the funds it requires to comply with its commitments including the 
inability to sell a financial asset quickly at a price close to its fair value. Management manages the risk by maintaining 
sufficient cash, marketable securities and ensuring access to financial institutions and shareholding funding. This ensures 
flexibility in maintaining business operations and maximises opportunities. The Group has available debt facilities of 
US$53.3 million at year end.

The table below summarises the maturity profile of the Group’s financial liabilities at 31 December based on contractual 
undiscounted payments:

The long-term incentive plans are described below:

Employee Share Option Plan (ESOP)
Certain key employees are entitled to a grant of options, under the ESOP of the Company. The vesting of the options is dependent 
on employees remaining in service for a prescribed period (normally three years) from the date of grant. The fair value of share 
options granted is estimated at the date of the grant using a Black Scholes simulation model, taking into account the terms and 
conditions upon which the options were granted. It takes into account projected dividends and share price fluctuation co-
variances of the Company.

There is a nil or nominal exercise price for the options granted at admission of the Company. The contractual life of the options is  
10 years and there are no cash settlement alternatives. The Company has no past practice of cash settlement.

Non-Executive share awards
In order to align the interests of the Chairman and independent Directors with those of the shareholders, the non-Executive 
Directors were invited to subscribe for shares at nominal value on terms set out in the prospectus. The non-Executive Directors shall 
not be eligible to participate in the short-term incentive bonus scheme (STIBS) or ESOP or any other performance-related incentive 
arrangements which may be introduced by the Company from time to time. There are currently no non-Executive share awards.

ESOP for September 2012 (LTIP)
On 11 September 2012, 936 000 nil-cost options were granted to certain key employees (excluding Executive Directors) under the 
LTIP of the Company. Of the total number of shares, 312 000 were nil value options and 624 000 were market value options. The 
exercise price of the market value options is £1.78 (US$2.85), which was equal to the market price of the shares on the date of grant. 
The awards which vest over a three-year period in tranches of a third of the award each year, dependent on the performance 
targets for the 2013, 2014 and 2015 financial years being met, are exercisable between 1 January 2016 and 31 December 2023. This 
award became exercisable on 1 January 2016. Of the 936 000 options originally granted, only 217 100 are still outstanding following 
the resignation of a number of employees and the exercising of these options.

25.

SHARE-BASED PAYMENTS (continued)
ESOP for March 2014 (LTIP)
In March 2014, 625 000 nil-cost options were granted to certain key employees under the LTIP of the Company. The vesting of the 
options will be subject to the satisfaction of certain performance as well as service conditions classified as non-market conditions. 
The options which vest over a three-year period in tranches of a third of the award each year are exercisable between 19 March 
2017 and 18 March 2024. If the performance or service conditions are not met, the options lapse. As the performance conditions 
are non-market-based they are not reflected in the fair value of the award at grant date, and therefore the Company will assess the 
likelihood of these conditions being met with a relevant adjustment to the cumulative charge as required at each financial year 
end. The fair value of the nil-cost options is £1.74 (US$2.87). Of the 625 000 options originally granted, only 297 271 are still 
outstanding following the resignation of a number of employees.

ESOP for June 2014 (LTIP)
In June 2014, 609 000 nil-cost options were granted to the Executive Directors under the LTIP of the Company. The vesting of the 
options will be subject to the satisfaction of certain market and non-market performance conditions over a three-year period. Of 
the 609 000 nil-cost options, 152 250 relates to market conditions with the remaining 456 750 relating to non-market conditions. 
The options which vest are exercisable between 10 June 2017 and 9 June 2024. If the performance or service conditions are not 
met, the options lapse. The performance conditions relating to the non-market conditions are not reflected in the fair value of the 
award at grant date. At each financial year end, the Company will assess the likelihood of these conditions being met with a 
relevant adjustment to the cumulative charge as required. The fair value of the nil-cost options relating to non-market conditions is 
£1.61 (US$2.70). The fair value of the options granted, relating to the market conditions, is estimated at the date of the grant using a 
Monte Carlo simulation model, taking into account the terms and conditions upon which the options were granted, projected 
dividends, share price fluctuations, the expected volatility, the risk-free interest rate, expected life of the options in years and the 
weighted average share price of the Company. Of the 609 000 options originally granted, only 560 839 are still outstanding 
following the resignation of an Executive Director during the year.

ESOP for April 2015 (LTIP)
In April 2015, 660 000 nil-cost options were granted to certain key employees under the long-term incentive plan (LTIP) of the 
Company. The vesting of the options will be subject to the satisfaction of certain performance as well as service conditions 
classified as non-market conditions. The options which vest after a three-year period are exercisable between 1 April 2018 and 
31 March 2025. If the performance or service conditions are not met, the options lapse. As the performance conditions are 
non-market-based they are not reflected in the fair value of the award at grant date, and therefore the Company will assess the 
likelihood of these conditions being met with a relevant adjustment to the cumulative charge as required at each financial year 
end. The fair value of the nil-cost options is £1.33 (US$1.97). Of the 667 500 options originally granted, only 472 608 are still 
outstanding following the resignation of a number of employees.

In addition, 740 000 nil-cost options were granted to the Executive Directors under the LTIP of the Company. The vesting of the 
options will be subject to the satisfaction of certain market and non-market performance conditions over a three-year period. Of 
the 740 000 nil-cost options, 185 000 relate to market conditions with the remaining 555 000 relating to non-market conditions. 
The options which vest are exercisable between 1 April 2018 and 31 March 2025. If the performance or service conditions are not 
met, the options lapse. The performance conditions relating to the non-market conditions are not reflected in the fair value of the 
award at grant date. At each financial year end, the Company will assess the likelihood of these conditions being met with a 
relevant adjustment to the cumulative charge as required. The fair value of the nil-cost options relating to the market conditions is 
£1.33 (US$1.97). The fair value of these options is estimated in a similar manner as the June 2014 LTIP. Of the 740 000 options 
originally granted, only 640 730 are still outstanding following the resignation of an Executive Director during the year.

ESOP for March 2016 (LTIP)
In March 2016, 1 400 000 nil-cost options were approved to be granted to certain key employees and Executive Directors under the 
LTIP of the Company. The vesting of the options will be subject to the satisfaction of certain market and non-market performance 
conditions over a three-year period. The satisfaction of certain performance as well as service conditions are classified as non-
market conditions. A total of 185 000 of the options granted relate to market conditions. The options vest after a three-year period 
and are exercisable between 15 March 2019 and 14 March 2026. If the performance or service conditions are not met, the options 
lapse. The performance conditions relating to the non-market conditions are not reflected in the fair value of the award at grant 
date, and therefore the Company will assess the likelihood of these conditions being met with a relevant adjustment to the 
cumulative charge as required at each financial year end. The fair value of the nil-cost options is £0.99 (US$1.40). The fair value of the 
options relating to market conditions is estimated in a similar manner as the June 2014 and April 2015 LTIP. Of the total options 
originally granted, 1 340 000 are still outstanding following the resignation of a number of employees.

The fair value of share options granted is estimated at the date of the grant using a Monte Carlo simulation model, taking into 
account the terms and conditions upon which the options were granted, projected dividends, share price fluctuations, the 
expected volatility, the risk-free interest rate, expected life of the option in years and the weighted average share price of 
the Company.

The carrying amounts of the Group’s financial instruments held approximate their fair value.

Fair value hierarchy
All financial instruments for which fair value is measured or disclosed in the financial statements are categorised within the fair 
value hierarchy, based on the lowest level input that is significant to the fair value measurement as a whole, as follows:
Level 1 – Quoted (unadjusted) market prices in active markets for identical assets or liabilities.
Level 2 – Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or 
indirectly observable. 
Level 3 – Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

There were no transfers between Level 1 and Level 2 fair value measurements or any transfers into or out of Level 3 fair value 
measurements during the period.

Other risk management activities
The Group is exposed to foreign currency risk on future sales of diamonds at Letšeng Diamonds. In order to reduce this risk, the 
Group enters into forward exchange contracts to hedge this exposure.  The Group performs no hedge accounting. During the 
current period the Group did not enter into any new forward exchange contracts due to the strong US dollar being favourable to 
the Group’s revenue.

EVENTS AFTER THE REPORTING PERIOD
Post-year end the outstanding balance of LSL28.0 million (US$2.0 million) on the three-year unsecured project debt facility at 
Letšeng, was fully repaid together with interest and net breakage costs.

Post-year end, following the decision to place the Ghaghoo mine on care and maintenance, the US$25.0 million term loan facility at 
Ghaghoo was settled in advance of its final repayment date using the US$35.0 million revolving credit facility held at the Company. 
The restricted cash of US$3.0 million reserved for a portion of the future repayment of the term loan facility at Ghaghoo was 
released at the same time.

No other fact or circumstance has taken place between the end of the reporting period and the approval of the financial 
statements which, in our opinion, is of significance in assessing the state of the Group’s affairs.
