Sterling Energy Plc  Report and Financial Statements 2012OVERVIEW

Chairman’s Statement

Sterling remains well funded and is actively pursuing new 
opportunities to broaden our exploration portfolio. During 
2012,  we  recruited  several  new  sub-surface  specialists 
to  work  under  our  Exploration  Director  who  joined  in 
November 2011; refreshment of our sub-surface team has 
increased the breadth and depth of our geological expertise 
and  experience.  The  team  has  screened  numerous  new 
ventures, reviewing several in detail, and, with the additional 
expertise  of  the  finance  and  legal  functions,  undertaken 
due diligence on several highly ranked opportunities, the 
more  attractive  being  presented  to  the  board.  However 
those  projects  supported  by  the  board  either  failed  to 
pass  the  higher  levels  of  due  diligence  undertaken  prior 
to execution of transaction documents, or were acquired 
by  others  who  appeared  to  be  able  and  willing  to  offer 
considerably larger consideration to the vendors. Some of 
the countries we have been actively looking at over the last 
12 months have become very popular with entry prices for 
new ventures reaching new highs. Whilst we continue to 
focus on Africa and the Middle East, we are now looking at 
other geographical areas. 

Our  most  recent  news  is  the  termination  of  the  Sangaw 
North  Production  Sharing  Agreement  (PSC),  bringing 
to  an  end  our  5-year  exploration  program  in  the  highly 
prospective  area  of  Kurdistan.  One  of  the  primary 
advantages  of  the  Sangaw  North  block  was  that  it 
contained one very large prospect requiring one exploration 
well to determine if it was to be a potentially commercial 
accumulation. The downside we have now experienced is 
that after the disappointing results announced in 2011, in 
our judgment there was little potential remaining. Following 
the acquisition of more 2D seismic in 2012, Sterling with its 
joint venture partner Addax Petroleum, decided not to drill 
a  further  exploration  well  and  to  subsequently  withdraw 
from the PSC.

Whilst  the  outcome  is  disappointing,  we  believe  the 
initial  resource  potential  of  the  Sangaw  North  block,  a 
view shared by Addax when they farmed-in and paid for 
our  drilling  costs,  justified  our  own  financial  exposure  in 
this  project.  Now  we  must  look  for  similar  ‘risk-reward’ 
opportunities, hopefully with a better outcome.

In  Cameroon  we  have  worked  with  Murphy  Oil,  who  is 
now the operator of the Ntem block, to refine the preferred 
choice  of  prospects  to  a  drill-ready  status.  We  remain 
excited  about  the  prospectivity  of  the  Ntem  block  and 
look forward to resuming our exploration of the block with 
the drill-bit when the resolution of the border dispute has 
progressed to the satisfaction of both us and our partners. 

In Madagascar we have made good progress with OMNIS, 
the  state oil company,  to  re-phase the outstanding work 
commitments  under  the  Ampasindava  and  Ambilobe 
licence agreements following the suspension of exploration 
activities after the change of government in March 2009. 
We  believe  the  various  parties  involved  in  the  roadmap 
towards democratic elections have agreed to reschedule 
the elections to later in 2013, which we expect to enable 
the resumption of operations in the country.  

FINANCIAL
The  Company  had  cash  resources  of  $120.3  million  at 
the  end  of  2012.  Our  work  programme  for  2013  is  fully 
funded  and  we  have  substantial  funds  available  for  new 
venture  activity.  We  remain  pleased  that  the  revenue 
from  Chinguetti  field  operations  in  Mauritania  continued 
to  provide  positive  cash  flow  during  2012  in  excess  of 
Sterling’s administrative costs.

CASH RESOURCES

We will remain focused on acquiring 
only those ventures which we believe 
will deliver real growth and value for 
our shareholders

OUTLOOK FOR 2013 AND BEYOND
We are optimistic that progress towards a resolution of the 
border dispute between Cameroon and Equatorial Guinea 
will  be  made  in  2013  and  we  are  ready  to  commence 
the  drilling  programme  to  evaluate  the  large  prospects 
identified from 3D seismic. In Madagascar the roadmap for 
elections  indicates  a  democratically  elected  government 
should be in place during 2013. We believe the Ntem and 
Ampasindava  blocks  contain  significant  potential  value 
waiting to be tested with the drill-bit. 

During 2013 our key objective is to add to our portfolio of 
assets.  We  will  look  both  within  and  beyond  our  legacy 
areas  for  the  right  opportunity  but  remain  focused  on 
acquiring only those ventures which we believe will deliver 
real growth and value for our shareholders.

2012 SUMMARY

Reached agreements for the prolongation of 
exploration licences in Madagascar and now 
awaiting ratification.

Completed exploration operations in the 
Sangaw North block in Kurdistan.

Received $12.7 million of net cash flow from 
Chinguetti field operations during 2012 (2011: 
$11.2 million).

Cash resources at 31 December 2012 of 
$120.3 million (2011: $115.8 million). 

I would like to thank our shareholders for their continuing 
interest  in  Sterling  and  all  our  staff  for  their  hard  work 
during 2012.

Company remains debt free.

Sterling Energy Plc  Report and Financial Statements 2012OVERVIEW

Chief Executive’s Review

Sterling  is  an  oil  and  gas  company  currently  focused  on 
exploration in Africa and the Middle East. The Company’s 
strategy continues to be to build shareholder value through 
participation in the exploration drilling of large exploration 
prospects whilst retaining a material working interest. The 
Company’s  existing  portfolio  consists  principally  of  large 
working  interests  in  high  materiality  exploration  licences 
acquired early in the exploration of an area. The Company 
has then advanced understanding of the exploration play 
through  the  acquisition  of  data  and  the  application  of 
technical  studies,  and  reduced  the  exploration  risk  to  a 
level that is commercially viable for the drilling of exploration 
wells.  When  appropriate  the  Company  has  introduced 
partners, generally through a farm-down process, to pay 
some, or all, of Sterling’s share of the costs of exploration 
drilling operations.

Following  the  completion  of  exploration  activities  in 
Kurdistan,  the  Company’s  exploration  portfolio  consists 
of  highly  prospective  interests  in  two  areas,  Cameroon 
and  Madagascar.  With  this  concentrated  portfolio,  the 
drilling of exploration wells is infrequent and the outcome 
of success or failure in any one well will greatly affect the 
longer  term  value  of  the  Company.  Success  in  any  one 
exploration well has the potential for very large returns for 
shareholders  and,  by  farming-down  a  proportion  of  our 
working interest in exchange for a third party to cover our 
share of the costs, the down side of our financial exposure 
is limited.

In  Kurdistan,  the  Company  completed  the  exploration  of 
the Sangaw North PSC area by acquiring and interpreting 
further  2D  seismic  data  targeting  the  potential  of  a 
secondary prospect along the flank of the main structure, 
analogous to discoveries made in adjacent acreage to the 
south  east.  Sterling,  along  with  our  joint  venture  partner, 
concluded that the risked potential did not justify the cost 
exposure  of  an  exploration  well  and  elected  to  withdraw 
from the PSC. Although the outcome from our exploration 

activities in Kurdistan has been disappointing, this venture 
offered shareholders the potential of a very large addition 
in value in the success case, with the downside limited by 
the farming out of a portion of the Company’s interest in 
return  for  a  carry  of  costs  through  the  drilling  of  the  first 
exploration well. 

In Cameroon, Sterling has conducted detailed interpretation 
of  the  reprocessed  3D  seismic,  completed  in  2011, 
increasing  the  Company’s  confidence  in  the  prospects 
previously  identified  within  the  licence  area.  A  stacked 
series of submarine fans, each having, in the Company’s 
best  estimate,  gross  un-risked  prospective  resources  of 
several hundred million barrels of recoverable oil, may offer 
the potential for multiple targets to be intersected by the 
first exploration well. While the overlapping maritime border 
claim between Equatorial Guinea and Cameroon has not 
yet  been  resolved,  we  believe  that  progress  continues 
and  that  the  joint  venture  partners,  Sterling  and  Murphy 
Cameroon Ntem Oil Co. Ltd (Operator), are well placed for 
the drilling of a very high potential exploration well.

In  Madagascar,  significant  progress  has  been  made,  in 
accordance with the ‘roadmap’ signed by the incumbent 
Government and their African neighbours in 2011, towards 
the  holding  of  democratic  elections  scheduled  to  take 
place in 2013. Sterling has material interests in two high 
potential exploration licences, Ambilobe and Ampasindava, 
located  in  the  deep  water  basins  offshore  north-west 
Madagascar.  The  Company  has  concluded  discussions 
with  OMNIS,  the  state  agency  managing  the  petroleum 
resources  of  Madagascar,  concerning  the  scheduling  of 
the exploration period in these licences, and expects that 
exploration activities will resume in both licences in 2013. 
On resumption, each licence will have the same remaining 
duration and obligations in the current exploration periods 
as existed in March 2009 when activities last took place. In 
Ampasindava, the large Sifaka prospect is now expected 
to be drilled during 2014 or 2015.

REVENUE

The Company has large working 
interest in high materiality exploration 
and is well placed to build the portfolio 
using existing resources

subsequent well drilling, and the acquisition of 2D seismic 
data  across  nearby  leads.  However,  Sterling  is  ready  to 
accelerate  activities  in  both  of  these  areas  should  the 
opportunity arise.

Sterling  has  a  strong  balance  sheet  with  cash  resources 
of  $120.3  million  at  31  December  2012  and  generates 
cash, from production, in excess of its administrative and 
overhead costs. The Company is confident that the external 
factors adversely influencing the existing exploration assets 
will be resolved in due course, and that it is well placed to 
build on the existing portfolio in a manner consistent with 
the Company’s strategy, using its existing resources.

Angus MacAskill
Chief Executive Officer
15 March 2013 

With the completion of exploration activities in Kurdistan, 
the  Company’s  exploration  portfolio  has  become  more 
concentrated.  Sterling’s  strategy  includes  the  expansion 
of the existing portfolio through the addition of exploration 
assets  offering  material  potential  value  to  shareholders. 
During 2012, the Company strengthened its technical and 
commercial  team,  completed  a  preliminary  screening  of 
many exploration opportunities in sub-Saharan Africa, and 
evaluated a number in more detail. Through this process, 
the Company identified several attractive opportunities to 
complement its existing portfolio. However, a combination 
of more detailed due diligence that identified unacceptable 
commercial and legal risks, and more aggressive bidding 
terms  by  our  peers,  resulted  in  no  new  ventures  being 
secured  during  the  period.  The  Company  continues  to 
identify and evaluate a number of interesting opportunities, 
and  the  expansion  of  the  existing  portfolio  will  be  a  key 
area of focus during 2013.

The Company also has an economic interest, approximately 
equivalent to 8%, in production from the Chinguetti field in 
Mauritania and a minor royalty interest in the surrounding 
exploration  acreage.  Chinguetti  is  a  mature  field  with  no 
further development planned. Gross oil production during 
2012 averaged approximately 6,256 barrels per day. Cash 
flow  from  our  interests  in  Chinguetti  currently  covers  the 
Company’s  administrative  overhead  costs  and  makes  a 
contribution to the cost of operations. Whilst the cash flow 
from this project is significant, this asset is not material in 
comparison to the future potential of our other projects.

Sterling’s  exploration  portfolio  consists  of  highly 
prospective  and  material  exploration  projects  in  two 
emerging exploration areas, Cameroon and Madagascar. 
As  both  are  progressing  slower  than  we  would  like,  due 
to external factors not controlled by Sterling, the planned 
exploration  programme  in  existing  assets  during  2013  is 
relatively modest and consists of the acquisition of a site 
survey  in  the  Ampasindava  licence,  in  preparation  for

CAMEROON
Ntem (WI 50%)
The  Ntem  concession  area  is  a  deep  water  block  situated 
in the southern Douala/Rio Muni Basin and lies adjacent to 
the  northern  maritime  border  of  the  Rio  Muni  province  of 
Equatorial Guinea. Water depths range from 400m to 2,000m 
across  the  block.  During  the  first  term  of  the  concession 
over 2,100km of 2D and 1,500km2 of 3D seismic data were 
acquired. Additional seismic and gravity data were purchased. 

This large block is undrilled and is well placed with respect 
to both Tertiary and Upper Cretaceous plays, which have 
both proved successful in West Africa. To the north of the 
block, Tertiary oil, gas and condensate discoveries made by 
Noble Energy commenced production in 2011, and Euroil 
(Bowleven)  continue  to  appraise  their  nearby  discoveries 
and are progressing these towards development.

During  2012  Sterling  interpreted  the  re-processed  3D 
seismic  data,  which  provided  significantly  improved  data 
quality and increased Sterling’s confidence in the material 
exploration prospects previously identified in the block. The 
Company is in the process of working up a full prospect 
inventory for the block and considers that a stacked series 
of submarine fans, offering the potential for multiple targets 
being intersected by one exploration well, are ready to drill. 
Current  work  confirms  the  significant  potential  of  these 
prospects, with each having gross un-risked prospective 
recoverable resources of several hundred million barrels.

In November 2011 Sterling completed a farm-out agreement 
with Murphy Cameroon Ntem Oil Co. Ltd (Murphy Oil), a 
wholly owned subsidiary of Murphy Oil Corporation under 
which Murphy Oil was assigned a 50% working interest in, 
and operatorship of, the Ntem concession. Sterling retains 
a  50%  non-operated  working  interest.  As  consideration, 
Murphy  Oil  paid  to  Sterling  a  contribution  towards  past 
costs  and  is  committed  to  fully  fund  joint  operations  in 
relation to the current phase of exploration.

Operations within the Ntem concession area are currently 
suspended  under  the  force  majeure  provisions  of  the 
licence  owing  to  an  overlapping  maritime  border  claim 
between Cameroon and Equatorial Guinea. The Company 
believes that both countries are actively working to resolve 
this issue and that the impact of the outcome will be either 
neutral  or  positive  to  the  Company’s  position.  However, 
it  is  possible  that  the  resolution  could  take  longer  than 
expected  and  that  the  outcome  could  have  a  negative 
effect on the Company’s position. 

When  force  majeure  is  lifted,  there  will  be  15  months 
remaining in the current exploration period which includes 
the  drilling  of  one  exploration  well.  Having  introduced  an 
experienced  deep  water  operator,  the  Company  is  well 
placed for this operation when it occurs.

MADAGASCAR
Sterling’s Ambilobe and Ampasindava blocks are located 
in  the  Majunga  and  Ambilobe  deep  water  basins, 
respectively, offshore north-west Madagascar. Exploration 
activity  in  these  blocks  continues  to  be  delayed  due  to 
the  political  situation  in  the  country  following  a  change 
of  Government  in  March  2009.  The  Government  of 
Madagascar  has  not  been  recognised  by  the  African 
Union or by the United Nations but in September 2011, the 
political parties in Madagascar agreed a process, prepared 
by the Southern African Development Community, which 
involved establishment of a Transitional Government, and 
with  the  objective  of  holding  democratic  elections  which 
are expected to take place in 2013.

During 2012, discussions continued with OMNIS, the state 
regulator,  and  formal  agreement  was  reached  to  prolong 
the  current  exploration  period  of  both  the  Ambilobe  and 
Ampasindava  production  sharing  contracts  with  each 
licence having the same remaining duration and obligations 
in the current exploration periods as existed in March 2009; 
in effect, the exploration periods will have been suspended 

10

Sterling Energy Plc  Report and Financial Statements 2012 
from March 2009 to when they resume. These agreements 
now await formal ratification by the Government.

Ampasindava (WI 30%)
The  production  sharing  contract  (PSC)  for  Ampasindava 
is  in  the  third  phase  of  the  exploration  period  with  a 
minimum  work  commitment  of  one  exploration  well. 
The  large  Sifaka  prospect  is  ready  to  drill  and  has  been 
independently  estimated  to  contain  gross  un-risked  best 
estimate  prospective  recoverable  resources  of  1.2  billion 
barrels  (RISC  Competent  Persons  Report,  March  2008). 
ExxonMobil  (WI  70%,  Operator)  and  Sterling  plan  to  drill 
this well once political stability is re-established.

Following the farm-in by ExxonMobil in 2005, Sterling’s costs 
are carried up to a fixed amount. The cost to drill the Sifaka 
prospect is estimated to exceed the remaining carry and the 
Company has started a farm-out process to introduce an 
additional partner, and reduce its current working interest, to 
cover these costs. It is currently unlikely that an exploration 
well will commence drilling before mid-2014.

Ambilobe (WI 100% and Operator)
The  PSC  for  Ambilobe  is  in  the  second  phase  of  the 
exploration  period.  All  work  commitments  have  been 
fulfilled by completing geological and geophysical studies 
and  acquiring  approximately  1,000km  of  2D  seismic.  A 
number of large Cretaceous and Tertiary leads have been 
identified, located in both shallow and deep waters, which 
will require additional seismic data to develop into potential 
drillable prospects. The Company has started a farm-out 
process  to  introduce  a  partner  to  carry  the  costs  of  the 
next  stage  of  exploration  which  is  likely  to  include  the 
acquisition  of  additional  seismic  data  to  define  the  leads 
that have been identified.

KURDISTAN
Sangaw North PSC (Relinquished)
The Sangaw North block lies in the foothills region of the 
Zagros fold belt, approximately 140km south east of Erbil, 
the capital of the Kurdistan region of Iraq. 

During  2012,  Sterling  completed  its  exploration  of  the 
Sangaw  North  block,  having  signed  the  Sangaw  North 
Production  Sharing  Contract  (“PSC”)  in  November  2007, 
targeting  high-impact  exploration  at  moderate  exploration 
risk, and in early 2013 the Company withdrew from the PSC.

In July 2008, Sterling entered into a farm-out agreement 
with  Addax  Petroleum  Sangaw  Limited  (Addax)  under 
which Addax paid Sterling’s past costs, seismic acquisition 
costs,  and  costs  for  drilling  the  first  exploration  well  on 
the  block,  excluding  testing.  Sterling  retained  a  53.33% 
interest in the PSC. 

Following  the  acquisition  of  325km  of  2D  seismic  in 
November  2008, 
the  Sangaw  North-1  exploration 
well  commenced  drilling  in  early  2010,  targeting  major 
exploration potential in Triassic, Jurassic, and Cretaceous 
aged formations within a large anticline structure. Five flow 
tests  were  conducted  with  gas  being  produced,  along 
with  formation  water,  in  all  five  of  the  flow  tests  at  rates 
that were not commercial and the well was plugged and 
abandoned. 

Having  identified  additional  exploration  potential,  the 
joint  venture  partners  entered  the  second  sub-period  of 
the  exploration  phase  of  the  PSC  in  November  2011.  
The  Company  completed  acquisition  of  a  further  117km 
of 2D seismic data in mid-2012. Interpretation of the new 
2D  seismic  data  indicated  that  the  risked  potential  of  a 
secondary prospect along the flank of the main structure, 
analogous  to  the  recent  discoveries  made  in  adjacent 
acreage to the south east of the Sangaw North PSC area, 
did not justify the cost exposure of an exploration well.

Operations Review (cont.)

A  farm-out  process  was  conducted  which  did  not  result 
in any offers of participation, indicating the wider industry 
concurred with the Company’s view. 

the Company’s economic interests, of 0.475 million barrels 
(2011: 0.664 million barrels).

No  in-fill  drilling  or  work-over  activity  took  place  on  the 
Chinguetti  field  during  2012.  Planned  shutdowns  were 
conducted over a total of 4 days in the second half of 2012 
for  maintenance  of  the  floating  production  and  storage 
facility and subsea equipment.

In  the  event  of  any  commercial  development  of  existing 
or future discoveries within the PSC-A, PSC-B and C-10 
contract areas, Sterling will be entitled to revenue, but will 
not  have  any  cost  obligations,  under  its  royalty  interest 
agreements with Premier Oil.

In  November  2012,  the  Banda  field,  located  in  PSC-A 
and operated by Tullow Oil Plc, was declared commercial 
and  it  is  planned  that  the  field  will  supply  gas  to  a  new 
local power station, subject to completion of a Gas Sales 
Agreement. 

Tullow Oil Plc plans to drill an exploration well in the C-10 
contract area in the second half of 2013.

Under  the  terms  of  the  PSC,  the  joint  venture  partners 
were required to notify the Kurdistan Regional Government 
of Iraq (KRG) on or before 31 January 2013 whether the 
partnership  intended  to  drill  a  further  exploration  well  on 
the  Sangaw  North  block.  On  29  January  2013,  Sterling 
notified the KRG of the joint venture partnership decision 
not to drill a second exploration well in the contract area 
and  the  PSC  automatically  terminated  on  that  date.  The 
work commitments under the PSC have been satisfied.

MAURITANIA 
Chinguetti  (Economic  Interest  via  Funding  and 
Royalty Agreements)
Sterling  has  economic  interests  in  the  Chinguetti  field 
through a funding agreement with Societe Mauritanienne 
Des  Hydrocarbures,  Mauritania’s  national  oil  company, 
and a royalty agreement with Premier Oil.

Gross  production  during  2012  averaged  6,256  bopd 
(2011:  7,250  bopd)  and  the  average  production  net  to 
Sterling,  from  the  Company’s  economic  interests,  during 
2012 was 523 bopd (2011: 629 bopd). Production in the 
first half of the year was reduced by a shutdown of 17 days 
due to a hydrate blockage in the gas pipeline connecting 
Banda  to  Chinguetti  and  a  further  shutdown  of  9  days 
due  to  a  failure  in  the  subsea  instrumentation  controlling 
the  operations  of  the  gas  well  in  the  Banda  field.  Gross 
production during the month of December 2012 averaged 
6,911 bopd (December 2011: 6,800 bopd).

Sterling  estimates  that  at  the  end  of  2012,  Chinguetti 
held  a  remaining  6.9  million  barrels  of  gross  proved  and 
probable  reserves  (2P)  that  could  be  accessed  with  the

Ntem (WI 50%)

OVERVIEW
The Ntem concession is a deep water block situated 
in  the  southern  Douala/Rio  Muni  Basin  and  lies 
adjacent  to  the  northern  maritime  border  of  the  Rio 
Muni  province  of  Equatorial  Guinea.  Water  depths 
range from 400m to 2,000m across the block. 

During the first term of the concession over 2,100km 
of  2D  and  1,500km2  of  3D  seismic  data  were 
acquired.  Additional  seismic  and  gravity  data  were 
also  purchased.  This  large  block  is  undrilled  and  is 
well placed with respect to both Tertiary and Upper 
Cretaceous plays. 

The  Ntem  concession  is  currently  in  force  majeure 
as  a  result  of  overlapping  maritime  border  claims 
between  Cameroon  and  Equatorial  Guinea.  Both 
countries  are  actively  working  to  resolve  this  issue. 
When force majeure is lifted, there will be 15 months 
remaining in the current exploration period. The work 
commitment in this period is 1 exploration well.

In November 2011, Murphy Cameroon Ntem Oil Co.

OPERATIONS

Madagascar

Ambilobe (WI 100%)

OVERVIEW
The Ambilobe block is located in the Ambilobe basin, 
offshore Madagascar. Water depths across the block 
range from shoreline to 3,000m. 

The  Phase  1  and  Phase  2  work  programme 
commitments  were  fulfilled  by  conducting  G&G 
studies, acquiring approximately 1,000km of new 2D 
seismic and processing more than 5,000km of new 
and vintage 2D seismic data. 

In  July  2005  Sterling  farmed  out  70%  interest  to 
ExxonMobil.  550km  of  new  2D  seismic  data  were 
purchased and more than 5,500km of 2D data were 
reprocessed. A number of large leads in Cretaceous 
and  Tertiary  plays  have  been  identified  which  will 
require additional seismic data to evaluate as potential 
drillable prospects.

In  May  2008,  Phase  2  of  the  exploration  period 
was  extended  by  1  year.  In  early  2009  ExxonMobil 
withdrew from the PSC and their interest reverted to 
Sterling. 

Prolongation of Phase 2 of the licence has been agreed 
with OMNIS and awaits Government ratification.

The drilling of the Sifaka prospect could be the first 
exploration  well  to  test  the  deep  water  potential  of 
Madagascar. Prolongation of Phase 3 of the licence 
has been agreed with OMNIS and awaits Government 
ratification.

Sterling estimates that ExxonMobil’s remaining carry 
at the beginning of 2012 is approximately $34 million 
towards the gross cost of drilling.

Ampasindava (WI 30%)

OVERVIEW
The  Ampasindava  block  is  located  in  the  Majunga 
basin, offshore Madagascar. Water depths across the 
block range from 20m to 2,500m. 

Sterling, as operator, fulfilled the Phase 1 and Phase 
2  work  programme  commitments  for  the  block  by 
completing  G&G  studies  and  acquiring  more  than 
3,000km of 2D seismic. In July 2005, Sterling farmed 
out  the  block  to  ExxonMobil.  Following  acquisition, 
processing and interpretation of the new 2D seismic 
data. Sterling transferred operatorship to ExxonMobil 
at the end of 2006.

In  late  2007  the  Sifaka  prospect  was  selected  as 
the  first  prospect  for  drilling  and  a  site-survey  was 
undertaken  in  2008.  In  November  2008  the  joint 
venture  partners  elected  to  enter  Phase  3  of  the 
exploration period which has a firm well commitment. 

The Sifaka Prospect is located in the inboard portion 
of the Ampasindava block, in water depths of 500m 
to 1,800m. Sifaka is mapped as a very large, simple 
structure  with  the  main  reservoir  target,  Jurassic 
deep-water  turbidite  sandstones,  expected  to  be 
encountered  at  approximately  3,000m  below  the 
seabed.

RISC (Competent Persons Report, March 2008) has 
estimated  the  gross  (100%)  un-risked  prospective 
recoverable  resources  for  the  Sifaka  prospect  as 
follows:

Low Estimate   150 million bbl
Best Estimate   1.2 billion bbl
High Estimate   4.8 billion bbl

Highlights
• Group net loss of $12.9 million in 2012 (2011: Profit $18.4 million)
• Impairment of Sangaw North licence $18.4 million following decision to relinquish
• Cash balance at year end of $120.3 million (2011: $115.8 million)
• Average 2012 Chinguetti production 523 bopd (2011: 629 bopd)
• Debt free throughout 2012

Revenue and Cost of Sales
2012  production  averaged  523  bopd,  including  Royalty  barrels,  a  decrease  of  17%  from  the  629  bopd  averaged 
in 2011. A large proportion of the decrease was due to isolated operational factors comprising a 17 day stoppage 
following a hydrate blockage and a 9 day stoppage following a failure of subsea instrumentation.

Currently, all of the Group’s production is from the Chinguetti field and the Group’s production was 536 bopd for the 
month of December 2012.

1 Net Sterling production during the year totalled 191,583

Gross volumes lifted and sold during the year were up by 28% to 2.6 million barrels (2011: 2.0 million barrels), due 
mainly to timing differences on liftings of oil stored in facilities at the Chinguetti field (2012: 3 liftings, 2011: 2 liftings).

20

Sterling Energy Plc  Report and Financial Statements 2012FINANCIAL REVIEWThe lifting cost per barrel has increased in 2012 by $20.2 to $54.9 (2011: $34.7). $9.8 of this increase relates to the 
increased per unit depletion of the Chinguetti asset (2011: $nil) following the $8.2 million impairment reversal in 2011 
with the balance of the increase due to additional maintenance costs and the payment of accumulated environmental 
contributions since the commencement of production in 2006.

In December 2012, the Group fully impaired its Sangaw North exploration asset following a decision to formally relinquish 
the  licence.  The  impairment  of  Sangaw  North  totalled  $18.4  million  (total  Group  impairment  expense  $18.1  million 
which include reversals of $324k with respect to former assets in Gabon). The Group’s direct operating costs increased 
by $3.8 million and depletion increased by $2.2 million following the reversal of prior year impairment losses in 2011.

Group  administrative  overhead  decreased  during  the  year  to  $2.8  million  (2011:  $3.7  million).  Included  within  this 
charge is $1.0 million (2011: $1.9 million) relating to share-based payment charges.

A portion of the Group’s staff costs and associated overheads are recharged to joint venture partners ($512k), expensed 
as pre-licence expenditure ($1.9 million), or capitalised ($1.9 million) where they are directly attributable to on-going 
capital projects. In 2012 this portion amounted to $4.3 million (2011: $5.1 million).

Sterling Energy Plc  Report and Financial Statements 2012FINANCIAL REVIEWStatement of Financial Position
At the year end, cash and cash equivalents totalled $120.3 million (2011: $115.8 million) of which unrestricted funds of 
$1.7 million (2011: $1.0 million) were held on behalf of partners, leaving a cash balance of $118.7 million (2011: $114.8 
million) available for Sterling’s own use at 31 December 2012. At the end of 2012, net assets / total equity stood at 
$104.6 million (2011: $116.1 million), and non-current assets were $16.7 million (2011: $31.3 million). This decrease is 
as a result of the impairment of the Sangaw North licence. Net current assets increased to $109.2 million (2011: $105.1 
million) due to the increased lifting revenues for 2012.

The Group’s Chinguetti decommissioning provision increased during the year by $1.0 million to $21.1 million (2011: 
$20.1million) due to the unwinding of liability to its present value. The provision continues to reflect the Group’s best 
estimate of this liability based on its estimate of the remaining economic field life. 

Cautionary Statement
This  financial  report  contains  certain  forward-looking  statements  that  are  subject  to  the  usual  risk  factors  and 
uncertainties  associated  with  the  oil  and  gas  exploration  and  production  business.  Whilst  the  Directors  believe  the 
expectation reflected herein to be reasonable in light of the information available up to the time of their approval of this 
report, the actual outcome may be materially different owing to factors either beyond the Group’s control or otherwise 
within the Group’s control but, for example, owing to a change of plan or strategy. Accordingly, no reliance may be 
placed on the forward-looking statements.

Year ended 31 December 2012

APPLICATION OF UK CORPORATE GOVERNANCE CODE PRINCIPLES 
The Directors are mindful of their duties and responsibilities to all Shareholders and of their statutory duties under the 
Companies Act, the core duty of which is to act in good faith and in a way most likely to promote the success of the 
Company for the benefit of its members as a whole. As an AIM listed company, the Company is not required to comply 
with the UK Corporate Governance Code, however, the Directors are committed to maintaining the highest standards 
of corporate governance. This statement describes how the Company has applied the main and supporting principles 
of corporate governance set out in the UK Corporate Governance Code published by the Financial Reporting Council 
in June 2010 (“Code”).

During the year, the Company has adhered to the provisions set out in the Code with the exception of the matters 
referred to below.

Provision D.1.3

Non-executive  Directors  (“NED”)  have  been  awarded  share  options  under  the  non-executive  Directors  Long  Term 
Incentive Plan (“NED LTIP”). The NED LTIP rules and option awards were approved by shareholders, as required under 
the Code, at the December 2009 extraordinary general meeting. Future NED LTIP awards will be awarded subject to 
approval by shareholders. Under the NED LTIP rules, shares acquired by the exercise of options were not required to 
be held for at least one year after the non-executive Director leaves the Board as required under the Code.

Amendments to the share options previously awarded under the NED LTIP and to the NED LTIP rules for any future 
awards, requiring shares acquired by the exercise of options to be held for at least one year after the non-executive 
Director leaves the Board, have been approved.

As of the date of publication of this Annual Report, the Company fully adheres to the provisions set out in the Code.

THE BOARD OF DIRECTORS AND ITS COMMITTEES
Board Composition, Operation and Independence
The Board currently comprises the executive Chairman, two executive Directors and three non-executive Directors. 
Each of the executive Directors has extensive knowledge of the oil and gas industry combined with general business and 
financial skills. All of the Directors bring independent judgement to bear on issues of strategy, performance, resources, 
key appointments and standards. The Board meets regularly throughout the year and all the necessary information is 
supplied to the Directors on a timely basis to enable them to discharge their duties effectively. 

The Board is responsible to the Shareholders for the proper management of the Company. A Statement of Directors’ 
Responsibilities in respect of the Financial Statements is set out on page 44.

The  Board  has  a  formal  schedule  of  matters  specifically  reserved  for  its  decision.  These  include  strategic  planning, 
business acquisitions or disposals, authorisation of major capital expenditure and material contractual arrangements, 
changes to the Group’s capital structure, setting policies for the conduct of business, approval of budgets, remuneration 
policy of Directors and senior management, and taking on debt and approval of Financial Statements. Other matters are 
delegated to the Committees of the Board and executive Directors, supported by policies for reporting to the Board. 

During the year share options have been issued to non-executive Directors under the NED LTIP (Keith Henry 103,150, 
Malcolm Pattinson 103,150 and Nicholas Clayton 103,150) subject to the approval by shareholders at the next Annual 
General Meeting. In the opinion of the Board the NED LTIP aligns the objectives of the non-executive Directors with 
those of Shareholders. The NED LTIP is not subject to performance conditions for independence reasons.

The Board considers each of the non-executive Directors to be independent.

Induction and Training
New Directors, on their appointment to the Board, are briefed by the Board and management on the activities of the 
Group and its key business and financial risks, the Terms of Reference of the Board and its Committees, the list of Board 
reserved matters, and the latest financial information about the Group. The Chairman ensures that Directors update 
their skills, knowledge and familiarity with the Company to fulfil their roles on the Board and on Board Committees. 
On-going training is available as necessary and includes updates from the Company Secretary on changes to the AIM 
rules, the Code, requirements under the Companies Act and other regulatory matters. Directors may consult with the 
Company Secretary at any time on matters related to their role on the Board. All Directors have access to independent 
professional advice at the Company’s expense.

Evaluation of the Board’s Performance
Performance  evaluation  takes  place  for  individual  Directors,  the  Board  and  its  Committees  and  includes  assessing 
the effectiveness of the Board as a whole. The evaluation of the performance of Directors is carried out using peer 
appraisal  questionnaires  which  combine  business  and  personal  performance  and  includes  discussions  with  the 
Senior Independent Director and the Senior Independent Director with the Chairman. Aspects of performance include 
attendance and participation at Board meetings, quality of involvement in Committees, commitment and effectiveness of 
their contribution to Board activities (including the AGM and shareholder communications), the adequacy of training and 
non-executive Directors’ independence. The process is conducted and reviewed by the Senior Independent Director, 
on behalf of the Nomination Committee; the Company Secretary is advised of its completion. The performance of the 
Chairman is reviewed annually in a meeting of the non-executive Directors, led by the Senior Independent Director. This 
review takes into account the views of executive Directors.

Retirement and Re-election
The Company’s Articles of association require that any Director who has been a Director at the preceding two Annual 
General Meetings and who was not appointed or re-appointed by the Company, retire and stand for re-election. All 
new Directors appointed since the previous Annual General Meeting need to stand for election at the following Annual 
General Meeting.

Corporate Governance (cont.)
Year ended 31 December 2012

COMMUNICATIONS WITH SHAREHOLDERS
The Board is accountable to the Company’s shareholders and as such it is important for the Board to appreciate the 
aspirations of the shareholders and equally that the shareholders understand how the actions of the Board and short-
term financial performance relate to the achievement of the Company’s longer term goals. 

The  Board  reports  to  the  shareholders  on  its  stewardship  of  the  Company  through  the  publication  of  interim 
and  final  results  each  year.  Press  releases  are  issued  throughout  the  year  and  the  Company  maintains  a  website  
(www.sterlingenergyplc.com)  on  which  press  releases,  corporate  presentations  and  the  Report  and  Financial 
Statements are available to view. Additionally this report and financial statement contains extensive information about 
the Company’s activities. Enquiries from individual shareholders on matters relating to the business of the Company are 
welcomed. Shareholders and other interested parties can subscribe to receive notification of news updates and other 
documents from the Company via email. In addition the executive Directors meet with major shareholders to discuss 
the progress of the Company.

The Executive Chairman provides periodic feedback to the Board following meetings with shareholders. The Senior 
Independent Director also attends some shareholder meetings to ensure the Board is appraised of all feedback provided 
by such meetings.

The Annual General Meeting provides an opportunity for communication with all Shareholders and the Board encourages 
the Shareholders to attend and welcomes their participation. The Directors attend the Annual General Meeting and are 
available to answer questions. Details of resolutions to be proposed at the Annual General Meeting to be held on 19 
April 2013 can be found in the notice of the meeting, on pages 94 to 98.

INTERNAL CONTROLS
In  September  1999  the  Turnbull  Guidance  (Internal  Control:  Guidance  for  Directors  on  the  Combined  Code)  was 
published, and revised in October 2005.

The Directors acknowledge their responsibility for establishing and maintaining the Group and the Company systems 
of internal control. These are designed to safeguard the assets of the Group and to ensure the reliability of financial 
information for both internal use and external publication. 

The  Group’s  internal  control  procedures  include  Board  approval  for  all  significant  projects.  All  major  expenditures 
require either senior management or Board approval at the appropriate stages of each transaction. A system of regular 
reporting covering both technical progress of projects and the state of the Group’s financial affairs provides appropriate 
information to management to facilitate control. The Board reviews, identifies, evaluates and manages the significant 
risks that face the Group.

Any  systems  of  internal  control  can  only  provide  reasonable,  and  not  absolute,  assurance  that  material  financial 
irregularities  will  be  detected  or  that  the  risk  of  failure  to  achieve  business  objectives  is  eliminated.  The  Directors, 
having  reviewed  the  effectiveness  of  the  system  of  internal  financial,  operational  and  compliance  controls  and  risk 
management, consider that the system of internal control operated effectively throughout the financial year and up to 
the date the financial statements were signed.

CONFLICTS OF INTEREST
The Company has in place procedures for the disclosure and review of any conflicts, or potential conflicts of interest 
which the Directors may have and for the authorisation of such conflicts by the Board. In deciding whether to authorise 
a conflict matter or a potential conflict the Directors must have regard to their general duties under the Companies Act 
2006.

Sterling Energy Plc  Report and Financial Statements 2012Remuneration Report
Year ended 31 December 2012

REMUNERATION COMMITTEE
The  Remuneration  Committee  is  comprised  of  Keith  Henry,  Nicholas  Clayton  and  Malcolm  Pattinson.  Keith  Henry 
is the Chairman of the Remuneration Committee. The Committee makes recommendations to the Board, within its 
agreed terms of reference, on the structure and overall remuneration package for executive Directors and reviews the 
remuneration for other senior employees. Non-executive Directors’ fees are considered and agreed by the Board.

The Remuneration Committee is permitted to appoint independent advisors to assist in the determination of remuneration. 

REMUNERATION POLICY
The  Company’s  policy  on  Directors’  remuneration  is  that  the  overall  remuneration  package  should  be  sufficiently 
competitive  to  attract,  retain  and  motivate  high  quality  executives  capable  of  achieving  the  Group’s  objectives  and 
thereby enhancing shareholder value. The package consists of salary, performance related bonus and share options 
awarded under the All Staff Long Term Incentive Plan, with the balance between these components being salaries at 
levels around the middle of the range of salaries for peer companies and material additional remuneration linked to 
performance  and  results  adding  materially  to  shareholder  value.  Sterling  acknowledges  the  benefit  of  the  executive 
Directors accepting appointments as non-executive Directors of other companies; if they accept more than two such 
appointments they are required to pass their fees for those appointments to the Company. The details of individual 
components of the executive remuneration package and service contracts are discussed below:

Basic Salary and Benefits: The salary and benefits are reviewed annually. Currently the Remuneration Committee 
uses remuneration data collected from published accounts and surveys of peer companies and does not use executive 
remuneration consultants. The Committee reviews this method on a regular basis. 

Performance  Related  Bonuses:  Performance  bonuses  are  awarded  to  executive  Directors  by  the  Board,  upon 
recommendations by the Remuneration Committee. Prior to each year the Remuneration Committee considers the levels 
of potential bonus payments and the corresponding set of objectives for which bonuses may be payable. Objectives are 
set to align the individuals’ motivation with the longer term sustainable future of the Company. These objectives may not 
provide short term or easily measurable results. At the end of each year the Remuneration Committee considers if the 
objectives have been achieved as well as individual contribution to the performance of the Group. The maximum level 
of performance bonus is capped at 100% of annual salary. Performance bonuses awarded to executive Directors are 
settled in shares in the Company which must be held for a minimum of 12 months after the award.

Results  Based  Long  Term  Incentive  Plans:  In  2009  the  Company  reviewed  the  existing  share-based  incentive 
schemes currently in place to motivate and incentivise its employees, and also took independent advice. Based on this 
review the Company proposed a new All Staff Long Term Incentive Plan (“All Staff LTIP”) as being the most effective way 
to deliver the incentives that the Board believes will continue to align the interests of the employees and shareholders. 
Shareholders approved this plan at the December EGM held on 22 December 2009. 

With effect from 2009, awards are made in the form of options to acquire shares in the Company at the shares’ nominal 
value. The All Staff LTIP is designed as a three year plan and the Company intends to grant annual awards in October 
each year based on the recommendations of the Remuneration Committee. 

Awards are made on similar terms to non-executive Directors of the Company, under a separate plan the NED LTIP. 
Awards under the NED LTIP are made by the Board and are not subject to performance conditions for independence 
reasons. 

Pensions: The Group operates a number of defined contribution pension schemes pursuant to which it contributes

FINANCIAL STATEMENTS

Director’s Report
Year ended 31 December 2012

The Directors present the Report and Financial Statements on the affairs of Sterling and its subsidiaries, together with 
the financial statements and auditors’ report for the year ended 31 December 2012.

PRINCIPAL ACTIVITY AND BUSINESS REVIEW
The principal activity of the Group and Company throughout the year remained the exploration for and production of oil 
and gas in Africa and the Middle East. The significant developments during 2012 and the other activities of the Group, 
as well as the future strategy and prospects for the Group, are reviewed in detail in the Chairman’s Statement, the Chief 
Executive’s Review, the Operational Review and the Financial Review.

The Group operates through overseas branches and subsidiary undertakings as appropriate to the fiscal environment. 
Significant subsidiary undertakings of the Group are set out in note 16 to the financial statements. 

The Group uses a number of key performance indicators (KPI’s) to assess the business performance against strategy. 
These are net debt ($), reserves (million boe), EBITDA ($), production (bopd) and share price growth. Analysis of the 
KPI’s can be found in the Financial Review on page 20. 

RESULTS AND DIVIDENDS
The Group loss for the financial year was $12.9 million (2011: profit of $18.4 million). This leaves an accumulated Group 
retained deficit of $423.1 million (2011: deficit $411.1 million) to be carried forward. The Directors do not recommend 
the payment of a dividend (2011: $nil).

GOING CONCERN
The Group business activities, together with the factors likely to affect its future development, performance and position 
are set out in the Operations Review on pages 10 to 15. The financial position of the Group and Company, its cash 
flows and liquidity position are described in the Financial Review on pages 20 to 23. In addition, note 25 to the financial 
statements include the Group’s objectives, policies and processes for managing its capital financial risk: details of its 
financial instruments and its exposures to credit risk and liquidity risk.

The Group has sufficient cash resources for its working capital needs and its committed capital expenditure programme 
at least for the next 12 months. As a consequence, the Directors believe that both the Group and Company are well 
placed to manage their business risks successfully despite the current uncertain economic outlook. 

The Directors have a reasonable expectation that the Group has adequate resources to continue in operational existence 
for the foreseeable future. Thus they continue to adopt the going concern basis of accounting in preparing the annual 
financial statements. 

CAPITAL STRUCTURE 
Details of the issued share capital, together with details of the movements in the Company’s issued share capital during 
the year, are shown in note 18 to the financial statements. The Company has one class of ordinary share which carries 
no right to fixed income. Each share carries the right to one vote at general meetings of the Company.

There are no specific restrictions on the size of a holding nor on the transfer of shares, which are both governed by 
the  general  provisions  of  the  Articles  of  Association  and  prevailing  legislation.  The  Directors  are  not  aware  of  any 
agreements between holders of the Company’s shares that may result in restrictions on the transfer of securities or on 
voting rights. Details of the employee share schemes are set out in note 26. No person has any special rights of control 
over the Company’s share capital and all issued shares are fully paid.

SUPPLIER PAYMENT POLICY AND PRACTICE
The  Company’s  and  Group’s  policy  is  to  settle  terms  of  payment  with  suppliers  when  agreeing  each  transaction, 
ensuring that suppliers are made aware of the terms of payment and abide by them. At the 2012 year end, the number 
of supplier days outstanding for the Group was 24 days (2011: 37 days).

CHARITABLE AND POLITICAL CONTRIBUTIONS
During the year the Group and Company made charitable donations of $870 (2011: $800), principally to local charities 
serving the communities in which the Group operates. No political contributions were made during the year (2011: $nil).

BUSINESS RISK
The Directors have identified the following current principal risks in relation to the Company’s future performance. The 
relative importance of risks faced by the Company can, and is likely to change with progress in the Company’s strategy 
and developments in the external business environment.

Strategic:
Strategy risk
The  Company’s  strategy  may  not  deliver  the  results  expected  by  shareholders.  The  Directors  regularly  monitor  the 
appropriateness of the strategy, taking into account both internal and external factors, and the progress in implementing 
the strategy, and modify the strategy as may be required based on results. Key elements of this process are annual 
business plans and strategy reviews, monthly reporting, and regular Board meetings.

Concentration risk
The Company’s portfolio of exploration assets has increased in concentration following the withdrawal from the Sangaw 
North PSC in Kurdistan. The Board has identified the broadening of the exploration portfolio, using the existing financial 
resources of the Company, as an important element of the Company’s strategy.

Competition risk
The  addition  of  exploration  licences  to  the  Company’s  portfolio  is  subject  to  increasing  competition  from  other 
companies. Many of the Company’s larger competitors have significantly greater financial and technical resources and 
are able to devote more to the development of their business. The Company mitigates this risk by choosing where and 
when to deploy its business development resources.

Operational:
Exploration risk
Exploration  activities  within  the  Company’s  licences  may  not  result  in  a  commercial  discovery.  The  historic  industry 
average  exploration  drilling  success  rate  is  approximately  one  success  for  every  five  wells.  There  is  no  certainty  of 
success from the existing portfolio.

40

Sterling Energy Plc  Report and Financial Statements 2012Sterling mitigates the exploration risk through the experience and expertise of the Company’s specialists, the application 
of  appropriate  technology,  and  the  selection  of  prospective  exploration  assets.  The  Company  has  an  objective  to 
acquire additional exploration assets, which will diversify exploration risk.

Operator risk
Sterling is not the operator of the Company’s licences where exploration drilling is anticipated as the next operational 
activity. The Company is dependent on other operators for the performance of activities and will be largely unable to 
direct, control or influence the activities and costs of the operators. 

By  farming  out  prior  to  drilling  activities,  the  Company  has  reduced  its  cost  exposure  and  transferred  operatorship 
to  other,  normally  larger  and  more  experienced,  operators  for  drilling  activities,  with  a  consequent  increase  in  the 
Company’s dependence on other operators for the performance of these activities.

Sterling carefully considers the technical and financial capability of company’s becoming operator of licences during a 
farm out process. Murphy Oil is the operator of the Ntem licence in Cameroon and ExxonMobil is the operator of the 
Ampasindava licence in Madagascar. 

External:
Country risk 
The Company’s assets are located in non-OECD countries. Governments, regulations, and the security environment 
may change with a consequential effect on the Company’s assets. The Company’s assets in Cameroon and Madagascar 
are currently affected by country-specific situations. 

In Cameroon, the Company holds a 50% working interest in the highly prospective Ntem block. The Governments of 
Cameroon and Equatorial Guinea are negotiating their joint maritime border, part of which runs concurrent with two of 
the Ntem block boundaries. The Company believes the final location of the maritime border will not impinge upon the 
Ntem area, however there is no certainty that, when agreement over the maritime border is reached, the Ntem acreage 
will remain as it is defined under the current licence agreement with the Cameroon Government. 

The Company has reached agreement with OMNIS, the state regulator in Madagascar, to prolong the Ampasindava 
and Ambilobe licences and awaits ratification by the Government of Madagascar; the existing exploration phase of 
each licence ended in November 2010. The Company believes the political roadmap towards elections is progressing 
well and expects a positive outcome. However there is no certainty of a positive outcome. 

Country risk is mitigated by monitoring the political, regulatory, and security environment within the countries in which 
Sterling holds assets, engaging in constructive discussions where and when appropriate, and introducing third-party 
expertise if this may assist in resolution of issues affecting the Company’s assets.

The Company has an objective to acquire additional assets for the exploration portfolio, which may assist in diversifying 
country risk.

In addition to the current principal risks identified above and general business risks, the Group’s business is subject to 
risks inherent in oil and gas exploration, development and production activities. There are a number of potential risks 
and uncertainties which could have a material impact on the Group’s long-term performance and could cause actual 
results to differ materially from expected and historical results. The Company has identified certain risks pertinent to its 
business including:

The Directors regularly monitor such risks, using information obtained or developed from external and internal sources, 
and will take actions as appropriate to mitigate these. Effective risk mitigation may be critical to Sterling in achieving 
its strategic objectives and protecting its assets, personnel and reputation. The Company has developed a business 
management system, including a risk management process which identifies key business risks and measures to mitigate 
these risks and then implements such measures considered appropriate. Other significant elements of the business 
management system include regular Board review of the business, defined process for preparation and approval of the 
annual work programme and budget, monthly management reporting, financial operating procedures, and HSES and 
anti-bribery management systems. 

42

Sterling Energy Plc  Report and Financial Statements 2012Sterling reviews its business risks and management systems on a regular basis and, through this process, the Directors 
have identified the principal risks. The Company manages some risks by maintaining a portfolio of projects and ensuring 
the Company is in compliance with the terms of all its agreements, through the application of appropriate policies and 
procedures implemented in the business management system, and via the recruitment and retention of a team of skilled 
and experience professionals. 

FINANCIAL INSTRUMENTS
Information about the use of financial instruments, the Group’s policy and objectives for financial risk management is 
given in note 25 to the financial statements.

AUDITORS
Each of the persons who are a Director at the date of approval of this Report and Financial Statements confirms that:

of any relevant audit information and to establish that the Company’s auditors are aware of that information.

This confirmation is given and should be interpreted in accordance with the provisions of section 418 of the Companies 
Act 2006.

BDO  LLP  has  expressed  its  willingness  to  continue  in  office  as  auditors  and  a  resolution  to  appoint  BDO  will  be 
proposed at the forthcoming Annual General Meeting.

Statement of Directors’ Responsibilities
Year ended 31 December 2012

The Directors are responsible for preparing the Report and Financial Statements in accordance with applicable law and 
regulations. 

Company law requires the Directors to prepare financial statements for each financial year. Under that law the Directors 
have  elected  to  prepare  the  Group  and  Company  financial  statements  in  accordance  with  International  Financial 
Reporting Standards (IFRSs) as adopted by the European Union. Under company law 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 
Company and of the profit or loss of the Group and Company for that period. The Directors are also required to prepare 
financial statements in accordance with the rules of the London Stock Exchange for companies trading securities on 
the Alternative Investment Market. 

In preparing these financial statements, the Directors are required to:
• select suitable accounting policies and then apply them consistently;
• make judgments and accounting estimates that are reasonable and prudent;
• state whether they have been prepared in accordance with IFRSs as adopted by the European Union, subject to any 

material departures disclosed and explained in the financial statements; and

• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the Company 

will continue in business.

The  Directors  are  responsible  for  keeping  adequate  accounting  records  that  are  sufficient  to  show  and  explain  the 
Company’s transactions and disclose with reasonable accuracy at any time the financial position of the Company and 
enable them to ensure that the financial statements comply with the requirements of the Companies Act 2006. They are 
also responsible for safeguarding the assets of the Company and hence for taking reasonable steps for the prevention 
and detection of fraud and other irregularities.

WEBSITE PUBLICATION
The Directors are responsible for ensuring the Report and Financial Statements are made available on a website. Financial 
statements are published on the Company’s website in accordance with legislation in the United Kingdom governing 
the preparation and dissemination of financial statements, which may vary from legislation in other jurisdictions. The 
maintenance and integrity of the Company’s website is the responsibility of the Directors. The Directors’ responsibility 
also extends to the on going integrity of the financial statements contained therein.

DIRECTORS’ RESPONSIBILITY STATEMENT
We confirm that to the best of our knowledge:
• the financial statements, prepared in accordance with International Financial Reporting Standards, give a true and fair 
view of the assets, liabilities, financial position and profit or loss of the Company and the undertakings included in the 
consolidation taken as a whole; and

• the Report and Financial Statements 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.

Sterling Energy Plc  Report and Financial Statements 2012Year ended 31 December 2012Notes to the Financial Statementsc) Going Concern
The Directors have, at the time of approving the financial statements, a reasonable expectation that the Group 
has adequate resources to continue in operational existence for the foreseeable future. Thus they continue to 
adopt the going concern basis of accounting in preparing the financial statements. Further detail is contained in 
the Directors’ Report.

d) Basis of Consolidation
The  consolidated  financial  statements  incorporate  the  financial  statements  of  the  Company  and  the  entities 
controlled by the Company (its subsidiaries) made up to 31 December each year. Control is achieved where 
the Company has the power to govern the financial and operating policies of an invested entity so as to obtain 
benefits from its activities.

The results of subsidiaries acquired or disposed of during the year are included in the consolidated statement of 
comprehensive income from the effective date of acquisition or up to the effective date of disposal, as appropriate.

Where  necessary,  adjustments  are  made  to  the  financial  statements  of  subsidiaries  to  bring  the  accounting 
policies used into line with those used by the Group. All intra-group transactions, balances, income and expenses 
are eliminated on consolidation.

As a consolidated Group statement of comprehensive income and expense is published, a separate statement 
of comprehensive income and expense for the parent Company has not been published in accordance with 
section 408 of the Companies Act 2006. 

e) Jointly Controlled Operations
Jointly controlled operations are arrangements in which the Group holds an interest on a long term basis which 
are  jointly  controlled  by  the  Group  and  one  or  more  ventures  under  a  contractual  arrangement.  The  Group’s 
exploration, development and production activities are sometimes conducted jointly with other companies in this 
way. Since these arrangements do not constitute entities in their own right, the consolidated financial statements 
reflect the relevant proportion of costs, revenues, assets and liabilities applicable to the Group’s interests.

f) Revenue
Sales of oil and gas are recognised, net of any sales taxes when goods are delivered or the title has passed to 
the customer. Interest income is accrued on a time basis by reference to the principal outstanding and at the 
effective interest rate applicable. Royalties and tariff income are recognised as earned on an entitlement basis. 
Dividend revenue from investments is recognised when the shareholders’ rights to receive payment have been 
established.

g) Oil and Gas Interests
Exploration and Evaluation Assets:
The Group accounts for oil and gas exploration under the full cost method having regard to the requirements of IFRS 
6 Exploration for and Evaluation of Mineral Resources. E&E costs are initially capitalised within intangible assets. 
Such E&E costs include licence acquisition costs, geological and geophysical costs, costs of drilling exploration 
and appraisal wells, and an appropriate share of overheads. E&E costs are capitalised and accumulated in cost 
pools which are not larger than a segment. Expenditures incurred before the Group has obtained the legal rights 
to explore a specific area are expensed in the year that they are incurred.

Costs relating to the exploration and evaluation of oil and gas interests are carried forward until the existence or 
otherwise of commercial reserves has been determined. 

57

Sterling Energy Plc  Report and Financial Statements 2012If  commercial  reserves  have  been  discovered,  the  related  E&E  assets  are  assessed  for  impairment  and  the 
resultant carrying value is then reclassified as oil and gas assets within property, plant and equipment, on a cost 
pool by cost pool basis. 

E&E assets that are determined not to have resulted in the discovery of commercial reserves remain capitalised 
as intangible E&E assets at cost, subject to the relevant cost pool meeting an impairment test as set out below. 

Under the full cost method, impairment tests on E&E assets are conducted on an individual cost pool basis, 
including any development or producing assets, when facts and circumstances suggest that the carrying amount 
in the pool may exceed its recoverable amount. Such indicators include the point at which a determination is 
made as to whether or not commercial reserves exist. The E&E assets are tested for impairment together with 
all development and production  assets associated with  that cost  pool, as a single cash-generating  unit. The 
aggregate carrying value is compared against the expected recoverable amount of the cost pool, generally by 
reference to the present value of the future cash flows expected to be delivered from production of commercial 
reserves.  Where  the  E&E  assets  to  be  tested  fall  outside  the  scope  of  any  established  cost  pool,  there  will 
generally be no commercial reserves and if the E&E is determined as unsuccessful the E&E assets concerned will 
be written off in full. Any impairment loss is separately recognised within the statement of comprehensive income.

Impaired assets are reviewed annually to determine whether any substantial change to their fair value amounts 
previously impaired would require reversal.

A previously recognised impairment loss is reversed if the recoverable amount increases as a result of a change in 
the estimates used to determine the recoverable amount, but not to an amount higher than the carrying amount 
that would have been determined (net of depletion or amortisation) had no impairment loss been recognised in 
prior periods. Reversal of impairments and impairment charges are credited / (charged) to a separate line item 
under total costs in the Consolidated Income Statement.

Refer to note 5 on page 65 for detailed disclosure of the results of impairments and impairment reviews performed.

Development and Production Assets:
Development and production assets are generally accumulated on a field-by-field basis and include the cost 
of developing the commercial reserves discovered and bringing  them into production, together with the  E&E 
expenditures, incurred in finding commercial reserves, transferred from intangible E&E assets as outlined above, 
which constitutes a single cash generating unit. Depletion is provided for on a cash-generating unit basis on a 
unit of production basis over the life of the proven and probable commercial reserves taking into account the 
expected future costs to extract all such reserves.

An impairment test is performed on an individual cash-generating unit whenever events and circumstances indicate 
that the carrying value of an asset may exceed its recoverable amount. The recoverable amount is assessed as 
the present value of the future cash flows expected to be derived from production of commercial reserves.

The cash-generating unit basis is generally the field, however, oil and gas assets, including infrastructure assets, 
may be accounted for on an aggregated basis where such assets are economically inter-dependent.

Property, Plant and Equipment Assets other than Oil and Gas Assets:
Property, plant and equipment other than oil and gas assets are stated at cost, less accumulated depreciation, 
and any provision for impairment. Depreciation is provided at rates estimated to write off the cost, less estimated 
residual value, of each asset over its expected useful life as follows:

Computer and office equipment – 33% straight line.

58

Sterling Energy Plc  Report and Financial Statements 2012Year ended 31 December 2012Notes to the Financial Statementsh) Decommissioning
Provisions for decommissioning costs are recognised in accordance with IAS 37 Provisions, Contingent Liabilities 
and Contingent Assets. Provisions are recorded at the present value of the expenditures expected to be required 
to settle the Group’s future obligations.

Provisions are reviewed at each reporting date to reflect the current best estimate of the cost at present value. 
The unwinding of the discount is reflected as a finance expense. A decommissioning asset is also established, 
since the future cost of decommissioning is regarded as part of the total investment to gain access to future 
economic benefits, and included as part of the cost of the relevant development and production asset. Depletion 
on this asset is calculated under the unit of production method based on commercial reserves. 

i) Intangible Royalty Interests
The  carrying  value  of  each  individual  royalty  interest  is  initially  stated  at  cost,  and  amortised  on  the  unit  of 
production  basis  relative  to  the  underlying  asset  and  assessed  individually  for  impairment  when  there  is  an 
indication that an impairment event may have occurred. 

j) Foreign Currencies
The US dollar is the functional and reporting currency of the Company and the reporting currency of the Group. 
Transactions  denominated  in  other  currencies  are  translated  into  US  dollar  at  the  rate  of  exchange  ruling  at 
the date of the transaction. Assets and liabilities in other currencies are translated into US dollars at the rate of 
exchange ruling at the reporting date. All exchange differences arising from such translations are dealt with in 
current year comprehensive income.

The results of entities with a functional currency other than the US dollar are translated at the average rates of 
exchange  during  the  period  and  their  statement  of  financial  position  at  the  rates  ruling  at  the  reporting  date. 
Exchange differences arising on translation of the opening net assets and on translation of the results of such 
entities are dealt with through the currency translation reserve. 

k) Taxation
Current Tax:
The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported 
in the statement of comprehensive income because it excludes items of income or expense that are taxable or 
deductible on other years and it further excludes items that are never taxable or deductible. The Group’s liability 
for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting date.

Deferred Tax:
Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of 
assets and liabilities in the financial statements and the corresponding tax bases used in the computation of 
taxable profit. Deferred tax liabilities are generally recognised for all taxable temporary differences and deferred 
tax  assets  are  recognised  to  the  extent  that  it  is  probable  that  taxable  profits  will  be  available  against  which 
deductible temporary differences can be utilised.

Deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries and 
associates, and interests in joint ventures, except where the Group is able to control the reversal of the temporary 
differences and it is probable that the temporary difference will not reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is 
no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. 

59

Sterling Energy Plc  Report and Financial Statements 2012Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or 
the asset is realised. Deferred tax is charged or credited in the statement of comprehensive income, except when 
it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets 
against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the 
Group intends to settle its current tax assets and liabilities on a net basis.

l) Investments (Company)
Non-current investments in subsidiary undertakings are shown in the Company’s Statement of Financial Position 
at cost less any provision for permanent diminution of value. 

m) Operating Leases
Rentals under operating leases are charged on a straight-line basis over the lease term. 

n) Financial Instruments
The Group’s Financial Instruments comprise of cash and cash equivalents, loans and receivables. There are no 
other categories of financial instrument. 

Trade Receivables:
Trade receivables are measured at amortised cost, unless the effect of the time value of money is immaterial. 
Appropriate  allowances  for  estimated  irrecoverable  amounts  are  recognised  in  profit  or  loss  when  there  is 
objective evidence that the asset is impaired.

Cash and Cash Equivalents:
Cash and cash equivalents comprise demand deposits, and other short term highly liquid investments, with an 
original maturity of less than 3 months, and are readily convertible to a known amount of cash and are subject to 
an insignificant risk of change in value.

The Group has the following financial liabilities, all are classified as held at amortised cost. The Group holds no 
other categories of financial liability.

Trade Payables:
Trade payables are stated at their amortised cost. 

Financial Liabilities and Equity:
Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements 
entered into. An equity instrument is any contract that evidences a residual interest in the asset of the Group after 
deducting all of its liabilities. Equity instruments issued by the Company are recorded at the proceeds received 
net of direct issue costs.

o) Pension Costs
The Group operates a number of defined contribution pension schemes. The amount charged to the Statement 
of  Comprehensive  Income  for  these  schemes  is  the  contributions  payable  in  the  year.  Differences  between 
contributions payable in the year and contributions actually paid are shown as either accruals or prepayments in 
the Statement of Financial Position.

Sterling Energy Plc  Report and Financial Statements 2012Year ended 31 December 2012Notes to the Financial Statementsp) Share-based Payments
The Company and Group have applied the requirements of IFRS 2 Share-based payments. The Company issues 
equity share-based payments to certain employees. The fair value of these awards has been determined at the 
date of the grant of the award allowing for the effect of any market-based performance conditions. This fair value, 
adjusted by the estimate of the number of awards that will eventually vest as a result of non-market conditions, 
is expensed uniformly over the vesting period. 

The fair values are calculated using an option pricing model with suitable modifications to allow for employee 
turnover before vesting and early exercise. The inputs to the model include: the share price at the date of grant; 
exercise price; expected volatility; expected dividends; risk-free rate of interest; and patterns of exercise of the 
plan participants.

Where the terms and conditions of options are modified before they vest, the increase in the fair value of the 
options, measured immediately before and after the modification, is also charged to the Consolidated Statement 
of Comprehensive Income over the remaining vesting period. 

q) Over/(Under) Lift
Lifting or off take arrangements for oil and gas produced in certain of the Group’s operations are such that each 
participant  may  not  receive  and  sell  its  precise  share  of  the  overall  production  in  each  period.  The  resulting 
imbalance between cumulative entitlement and cumulative liftings is ‘underlift’ or ‘overlift’. Underlifts and overlifts 
are valued at the lower of cost and net realisable value and overlifts are valued at market value. Adjustments are 
made to cost of sales and balances included within receivables and payables as appropriate. 

r) Inventories
The  Group’s  share  of  any  material  and  equipment  inventories  is  accounted  for  at  the  lower  of  cost  and  net 
realisable value. Net realisable value is the estimated selling price less the estimated costs of completion and the 
estimated costs necessary to make the sale. The cost of inventories comprises all costs of purchase, costs of 
conversion and other costs incurred in bringing the inventories to their present location and condition.

s) Provisions
Provisions are recognised when the Group has a present obligation as a result of a past event and it is probable 
that the Group would be required to settle that obligation. Provisions are measured at the management’s best 
estimate of the expenditure required to settle the obligation at the reporting date, and are discounted to present 
value where the effect is material.

t) Segment Reporting
Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating 
decision makers. The chief operating decision makers have been identified as the executive Board members.

The operating results of each of the geographical segments are regularly reviewed by the Group’s chief operating 
decision makers in order to make decisions about the allocation of resources and to assess their performance. 
Africa has exploration and development activities, the Middle East has exploration activities (discontinued) and 
the United Kingdom office is an administrative cost centre.

CRITICAL ACCOUNTING JUDGEMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY

In the application of the Group’s accounting policies, which are described in note 1, the Directors are required 
to make judgements, estimates and assumptions about the carrying amounts of assets and liabilities that are 
not  readily  apparent  from  other  sources.  The  estimates  and  associated  assumptions  are  based  on  historical 
experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an on-going basis. Revisions to accounting estimates 
are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period 
of the revision and future periods if the revision affects both current and future periods.

The key assumptions concerning the future, and other key sources of estimation uncertainty at the reporting 
date, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities 
within the next financial year, are discussed below.

Commercial Reserves 
Commercial reserves are proven and probable oil and gas reserves, calculated on an entitlement basis. Estimates 
of  commercial  reserves  underpin  the  calculation  of  depletion  and  amortisation  on  a  unit  of  production  basis. 
Estimates of commercial reserves include estimates of the amount of oil and gas in place, assumptions about 
reservoir performance over the life of the field and assumptions about commercial factors which, in turn, will be 
affected by the future oil and gas price.

Impairment of Assets
Management  is  required  to  assess  oil  and  gas  assets  for  indicators  of  impairment  and  have  considered  the 
economic value of both the Chinguetti Funding and Royalty Agreements and specifically whether further historic 
impairments should be reversed. The carrying value of oil and gas assets is disclosed in notes 13, 14 and 15. 
The carrying value of related investments in the Company statement of financial position is disclosed in note 
16. As part of this assessment, management has carried out an impairment test on the Chinguetti oil and gas 
assets within property, plant and equipment. This test compares the carrying value at the reporting date with the 
expected discounted cash flows from the relevant projects. 

For the discounted cash flows to be calculated, management has used a production profile based on its best 
estimate of proven and probable reserves and a range of assumptions including a 10% pre-tax discount rate 
and an internally estimated oil price profile. Exploration and evaluation assets are subject to a separate review 
for  indicators  of  impairment,  by  reference  to  the  impairment  indicators  set  out  in  IFRS  6,  which  is  inherently 
judgemental.

Decommissioning
The  Group  has  obligations  in  respect  of  decommissioning  in  Mauritania.  The  extent  to  which  a  provision  is 
recognised depends on the legal requirements at the date of decommissioning, the estimated costs and timing 
of the work and the discount rate applied. Decommissioning estimates for the Chinguetti field are based on a 
range of operator estimates which are periodically reviewed by the operator and the Chinguetti partners. Sterling 
believes the field could be abandoned earlier than originally planned and allowance has been made for this in the 
calculation of the obligation.

Share-based Payments 
Management is required to make assumptions in respect of the inputs used to calculate the fair value of share-
based payment arrangements. Details of these can be found in note 26.

OPERATING SEGMENTS

The Group’s two operating segments are its Africa and Middle East (discontinued) segments. The UK corporate 
office is a technical and administrative cost centre. The operating results of each of these segments are regularly 
reviewed  by  the  Group’s  executive  Directors  and  senior  management  in  order  to  make  decisions  about  the 
allocation of resources and to assess their performance.

The accounting policies of these segments are in line with those set out in note 1.

The  following  tables  present  revenue,  profit  and  certain  asset  and  liability  information  regarding  the  Group’s 
operating segments for the year ended 31 December 2012, and for the year ended 31 December 2011.

During the year the Company fully impaired all capitalised expenditure totalling $18.4 million (2011: $nil) on the 
Sangaw North licence following the decision to relinquish the block. Full details of the impairment and financial 
impact are disclosed in note 10 on pages 67 and 68. 

In  2011  the  Company  reversed  impairments  totalling  $8.3  million  in  accordance  with  IAS  36  “Impairment  of 
Assets” following a review by the operator of forecast field life estimations on the Chinguetti field in Mauritania. 
This  review  resulted  in  an  extension  of  the  economic  field  life  to  better  reflect  decline  rates  that  have  been 
regressing  less  aggressively  than  originally  prognosed.  Of  the  $8.3  million,  $5.6  million  relates  to  reversals  of 
prior period impairment losses on the Chinguetti Funding Agreement and $2.7 million to reversals of prior period 
impairment losses on the Chinguetti Intangible Royalty Asset.

2011 Impairment reversals had been determined by estimating the value in use and resulted in an increase in field 
reserves of 0.472 million barrels of oil (Reserves Summary page 16). In calculating this impairment, management 
used a range of assumptions, including a long-term oil price of $85 per barrel and a 10% pre-tax discount rate.

On 29 January 2013, Sterling formally announced withdrawal from the Sangaw North licence in Kurdistan. The 
decision to relinquish was made in December 2012 following interpretation of the 2D seismic data acquired in the 
Sangaw North PSC earlier in 2012. This indicated that the remaining potential was insufficient to justify drilling a 
second exploration well in the contract area.

Sterling  acquired  and  processed  117km  of  2D  seismic  data,  supplementing  the  2D  seismic  data  previously 
acquired  in  the  contract  area.  Interpretation  of  the  new  seismic  data  indicated  that  the  risked  potential  of  a 
secondary target along the flank of the main structure, analogous to the recent discoveries made in adjacent 
acreage to the south east of the Sangaw North PSC area, did not justify the cost exposure of an exploration 
well. Based on this interpretation, the joint venture partnership has decided not to drill a second exploration well 
in the contract area.

Under the terms of the PSC, Sterling were required to notify the Kurdistan Regional Government of Iraq (KRG) on 
or before 31 January 2013 whether or not they wished to participate in the drilling of a further exploration well on 
the Sangaw North block before the end of the current exploration phase which ran to November 2013.

On 30 December 2012, Sterling fully impaired all expenditure capitalised on the Sangaw North block following 
a  decision  by  the  Board  to  relinquish  the  licence.  Details  of  the  financial  impact  of  the  relinquishment  are 
summarised below:

On 29 January 2013, Sterling notified the KRG of the partnership’s decision not to drill a second exploration well 
in the Sangaw North PSC area and the PSC automatically terminated on that date.

At the date of termination, Sterling had fully satisfied the work commitment required by the Sangaw North PSC. 
Following the closure of Sangaw North operations, Sterling will have no remaining interests in Kurdistan.

11.  PROFIT ATTRIBUTABLE TO THE COMPANY

The loss for the financial year dealt within the Company accounts of Sterling Energy Plc was $8.6 million (2011: 
profit of $1.6 million). As provided by s408 of the Companies Act 2006, no individual statement of comprehensive 
income and expense is provided in respect of the Company.

12.  EARNINGS PER SHARE

The calculation of basic loss per share is based on the Group consolidated loss for the financial year of $12.9 
million (2011: profit $18.4 million) and on 219,530,061 (2011: 219,382,869) ordinary shares, being the weighted 
average number of ordinary shares in issue. For the year ended 31 December 2012, the basic loss per share 
were 5.89 US¢ per share (2011: profit 8.40 US¢ per share). 

For the year ended 31 December 2012, the fully diluted loss per share was 5.89 US¢ per share (2011: profit 8.29 
US¢ per share). This is computed based on 219,530,061 (2011: 222,292,291) ordinary shares, being the total 
used for the computation of the basic earnings per share as adjusted in assuming the exercise of none of the 
11,409,488 options outstanding as at the year end (see note 26 on pages 80 to 84).

For the year ended 31 December 2012, the basic and fully diluted loss per share from discontinued operations 
was 8.38 US¢ per share (2011: nil US¢ per share). The loss from discontinued operations during the year was 
$18.4 million (2011: $nil).  The profit from continuing operations was $5.5 million (2011: $18.4 million).

Group net book value at 31 December 2012 comprises the value of rights to future royalties in respect of the 
Group’s agreements covering licences PSC A and PSC B and PSC C-10 in Mauritania. The value of these royalty 
interests is dependent upon future oil and gas prices and the development and production of the underlying oil 
and gas reserves.

An impairment assessment and any subsequent charge are calculated on an individual royalty interest basis.

expected to be derived from the production of commercial reserves in these licences and are compared against 
the carrying value of these assets.

In 2011 impairment losses recognised in prior periods totalling $2.7 million have been reversed on the Chinguetti 
asset. Details of impairment losses can be found in note 1 on page 58 and note 5 on page 65.

The  amount  for  intangible  exploration  and  evaluation  assets  represents  investments  in  respect  of  exploration 
licences (see note 1g). Impairment tests on E&E assets are conducted on an individual cost pool basis when 
facts and circumstances suggest that the carrying amount in the pool may exceed its recoverable amount. 

The impairment reversal recorded above relates to assets held in the Africa pool of $324k (2011: impairment 
$33k) where the estimated recoverable amount of the property, plant and equipment and E&E in the pool was in 
excess of the carrying amount.

Capital Risk Management and Liquidity Risk
The  Group  and  Company  is  not  subject  to  externally  imposed  capital  requirements.  The  capital  structure  of 
the Group and Company consists of cash and cash equivalents held for working capital purposes and equity 
attributable  to  the  equity  holders  of  the  parent,  comprising  issued  capital,  reserves  and  retained  deficit  as 
disclosed in the statement of changes in equity. The Group and Company uses cash flow models and budgets, 
which are regularly updated, to monitor liquidity risk.

Significant Accounting Policies
Details  of  the  significant  accounting  policies  and  methods  adopted,  including  the  criteria  for  recognition,  the 
basis of measurement and the basis on which income and expenses are recognised, in respect of each material 
class of financial asset, financial liability and equity instrument are disclosed in note 1 to the financial statements. 

Due  to  the  short  term  nature  of  these  assets  and  liabilities  such  values  approximate  their  fair  values  at  
31 December 2012 and 31 December 2011.

Sterling Energy Plc  Report and Financial Statements 2012Financial Risk Management Objectives
The Group’s and Company’s objective and policy is to use financial instruments to manage the risk profile of its 
underlying operations. The Group continually monitors financial risk including oil and gas price risk, interest rate 
risk, equity price risk, currency translation risk and liquidity risk and takes appropriate measures to ensure such 
risks are managed in a controlled manner including, where appropriate, through the use of financial derivatives. 
The  Group  and  Company  does  not  enter  into  or  trade  financial  instruments,  including  derivative  financial 
instruments, for speculative purposes.

Interest Rate Risk Management
The Group and Company does not have any outstanding borrowings and hence, the Group and Company is 
only exposed to interest rate risk on its short term cash deposits. 

Interest Rate Sensitivity Analysis
The sensitivity analysis below has been determined based on the exposure to interest rates for derivative and 
non-derivative instruments at the reporting date and assuming the amount of the balances at the reporting date 
were outstanding for the whole year.

A  100  basis  point  change  represents  management’s  estimate  of  a  possible  change  in  interest  rates  at  the 
reporting date. If interest rates had been 100 basis points higher and all other variables were held constant the 
Group’s profits and equity would be impacted as follows:

Foreign Currency Risk
The Group’s and Company’s reporting currency is the US dollar; being the currency in which the majority of the 
Group’s revenue and expenditure is transacted. The US dollar is the functional currency of the Company and 
the majority of its subsidiaries. Less material elements of its management, services and treasury functions are 
transacted in pounds sterling. The majority of balances are held in US dollars with transfers to pounds sterling 
and other local currencies as required to meet local needs. The Group does not enter into derivative transactions 
to manage its foreign currency translation or transaction risk.

The Group and Company’s foreign currency translation risk is as follows:

Credit Risk Management
Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss 
to the Group or Company. The Group and Company reviews the credit risk of the entities that it sells its products 
to  or  that  it  enters  into  contractual  arrangements  with  and  will  obtain  guarantees  and  commercial  letters  of 
credit as may be considered necessary where risks are significant to the Group or Company. The Group’s and 
Company’s business is diversified in terms of both region and the number of counter-parties and the Group and 
Company does not have significant exposure to any single counter-party or Group and Company of counter-
parties with similar characteristics.

In relation to its cash and cash equivalents, the Group has to manage its currency exposures and the credit risk 
associated with the credit quality of the financial institutions in which the Group maintains its cash resources. At the 
year end the Group held approximately 92% (2011: 88%) of its cash in US dollars. At the year end the Group held 
the majority of its balances with AA- and A+ Standard & Poors rated institutions. The Group continues to monitor 
its treasury management to ensure an appropriate balance of the safety of funds and maximisation of yield.

During the year the Company impaired loans to Sterling Energy International Limited totalling $17.6 million (2011: $nil) 
following the relinquishment of its Sangaw North licence in Kurdistan. Trade and other receivables are non-interest 
bearing. The Group does not hold any collateral as security and the Group does not hold any significant provision in 
the impairment account for trade and other receivables as they relate to customers with no default history.

Liquidity and Interest Rate Tables
The following tables detail the remaining contractual maturity for the non-derivative financial assets and liabilities 
of the Group and Company. The tables have been drawn up based on the undiscounted cash flows of financial 
liabilities based on the earliest date on which the Group can be required to pay. The table includes both interest 
and principal cash flows including rates for loan liabilities and cash deposits on actual contractual arrangements. 
The weighted average interest rate used in 2012 is nil% (2011: nil%).

Upside Sharing Agreement
Following the sale of Sterling’s U.S. operations to Atinum E&P Inc. (“Atinum”) in 2009 the Company held a three 
year ‘upside sharing agreement’, under which the Company is entitled to a 40% share of the annual excess 
net production proceeds, net of certain costs, if Atinum’s average realised oil price exceeds $90 bbl and/or the 
realised gas price exceeds $9 mcf in 2010-2012.

The Company has modelled the value of each of the embedded derivatives (for oil and gas production) using a 
DCF model at prevailing oil and gas prices. The DCF model takes account of production profiles, appropriate 
discount factors and costs, hedges and other contractual terms. 

At 31 December 2012 the value of the upside sharing agreement was $nil (31 December 2011: $nil). The Group 
has no financial obligation in respect of this agreement, which has now fully expired, with no amounts falling due.

26.  SHARE-BASED PAYMENTS

The Group recognised a total expense, within administration costs, in respect of share-based payments under 
equity-settled share option plans of $973k (2011: $1.9 million). The Company recognised a total expense, within 
administration  costs,  in  respect  of  share-based  payments  under  equity-settled  share  option  plans  of  $184k 
(2011: $255k).

In 2009 the Company reviewed the existing share-based incentive schemes currently in place to motivate and 
incentivise  its  employees.  The  Company  also  took  independent  advice  to  support  its  review.  Based  on  this, 
the  Company  proposed  a  new  All  Staff  Long  Term  Incentive  Plan  as  being  the  most  effective  way  to  deliver 
the incentives that the Board believes will continue to align the interests of the employees and shareholders. 
Shareholders approved this plan at the December EGM held on 22 December 2009. 

With effect from 2009, all further awards are made under the All Staff Long Term Incentive Plan. Awards are 
made on similar terms to non-executive Directors of the Company, under a separate plan the NED Long Term 
Incentive Plan.

No share options were exercised during 2012 (2011: nil). The options outstanding at the end of the year have a 
weighted average contractual life of 0.60 years (2011: 1.18 years). The cost of share options is spread over the

All options are equity settled. The vesting period is three years. If the options remain unexercised after a period 
of five years from the date of grant, the options expire. Options are forfeited if the employee leaves the Group 
before the options vest or are exercised.

The options outstanding at the year end have a contractual life of 4.14 years (2011: 4.10 years). The cost of the 
options is spread over the vesting period of three years. The fair value of the options granted during the year was 
20.4 pence (2011: 15.45 pence).

If the Sterling Energy share price (“SESP”) under-performs the Index performance by 10% or more, then no share 
options will be earned and the share options will lapse.

If the SESP performance is between matching the Index and under-performing by 10%, the amount of the share 
options that will be earned will be determined by extrapolating on a 2.5:1 straight line basis.

82

Sterling Energy Plc  Report and Financial Statements 2012Year ended 31 December 2012Notes to the Financial StatementsIf the SESP performance matches the Index performance, then 25% of the share options will be earned.

If the SESP performance is between matching the Index and out-performing by 50%, the amount of the share 
options that will be earned will be determined by extrapolating on a 1.5:1 straight line basis.

If the SESP out performs the Index performance by 50% or more, then 100% of the share options will be earned.

All  performance  measures  are  defined  as  being  the  absolute  share  price  performance  or  absolute  index 
performance, and not the performance relative to each other.

Fair values were measured by use of a modified binomial model. The inputs to the basic binomial model were 
as follows:

Share price (pence)

Exercise price (pence)

Expected volatility at time of grant

Expected life (years)

Risk free rate (%)

Expected dividends

Expected volatility for grants in the year was estimated by calculating the historical volatility of the Company’s 
share price over the period 23 December 2009 to 30 September 2012 (2011: over the period 23 December 
2009 to 30 September 2011). The Company has overlaid a normal distribution for the FTSE350 condition to 
assess a range of possible outcomes.

The Company has then compared the SESP performance against the range of Index performance to estimate 
the  vested  proportions  of  share  options  in  accordance  with  the  scheme  rules.  Weighting  factors  based  on 
probabilities under the normal distribution are then applied to the range of share option values to calculate a 
weighted-average share option value.

Non-executive Directors Long Term Incentive Plan (‘NED LTIP’)
In accordance with the approved NED LTIP, the Group has granted options to its non-executive Directors to 
acquire shares in the Company.

of five years from the date of grant, the options expire.

Furthermore, options are forfeited if the employee leaves the Group before the options vest or are exercised. 
The options outstanding at the year end have a contractual life of 3.39 years (2011: 3.20 years). The cost of the 
options is spread over the vesting period of three years. The fair value of the options granted during the year was 
20.4 pence (2011: n/a pence).

No performance criteria are attached to the outstanding options, other than the requirement that the holders 
must remained employed by the Group when the options are exercised, unless employment is terminated on 
death, or as a good leaver. 

Fair values were measured by use of a binomial model, using the same inputs as the basic (pre-modified) model 
for the All Staff Long Term Incentive Plan above.

Explanatory Notes to the Resolutions
The following explanatory information is provided by way of background to the business of the meeting:

Resolution 2
This resolution is to approve the Directors’ Remuneration Report for the financial year ended 31 December 2012. 
You can find the report on pages 32 to 35 of the Report and Financial Statements 2012.

Resolution 5
Biographical  details  of  the  Director  standing  for  re-election  (Nicholas  John  Clayton)  appear  on  page  25  of  the 
Report and Financial Statements 2012.

Resolution 6
Biographical details of the Director standing for re-election (Keith Nicholas Henry) appear on page 26 of the Report 
and Financial Statements 2012.

Resolution 7
Your  Directors  may  allot  shares  and  grant  rights  to  subscribe  for,  or  convert  any  security  into,  shares  only  if 
authorised to do so by shareholders. The authority granted at the last Annual General Meeting is due to expire at 
this year’s Annual General Meeting. Accordingly, Resolution 7 will be proposed as an ordinary resolution to grant 
new authorities to allot shares and grant rights to subscribe for, or convert any security into, shares (a) up to an 
aggregate nominal amount of £29,340,469  and (b) in connection with a rights issue up to an aggregate nominal 
amount (including allotments under part (a) of the resolution) of £58,680,939.

These amounts represent approximately one third and approximately two thirds respectively of the total issued 
ordinary share capital of the Company at 15 March 2013, in accordance with current guidelines of the Association 
of British Insurers (the “ABI”) insofar as they affect the Company. If given, these authorities will expire at the next 
Annual General Meeting of the Company or on 30 June 2014, whichever is the earlier. Your Directors have no 
present intention of issuing shares pursuant to this authority.

Resolution 8
Your Directors also require additional authority from shareholders to allot equity securities or sell treasury shares 
where  they  propose  to  do  so  for  cash  and  otherwise  than  to  existing  shareholders  pro  rata  to  their  holdings. 
The authority granted at the last Annual General Meeting is due to expire at this year’s Annual General Meeting. 
Accordingly, Resolution 8 will be proposed as a special resolution to grant such authority. Apart from offers or 
invitations in proportion to the respective number of shares held, the authority will be limited to the allotment of 
equity securities and sales of treasury shares for cash up to an aggregate nominal value of £4,401,070 (being 5% 
per cent of the Company’s issued ordinary share capital at 15 March 2013). If given, this authority will expire at 
the next Annual General Meeting of the Company or on 30 June 2014, whichever is the earlier. Your Directors do 
not have any present intention of exercising this authority, but consider it desirable to have the flexibility to use it 
should opportunities arise. Your Directors will have due regard to institutional guidelines in relation to any exercise 
of this authority, in particular, the requirement for advance consultation and explanation before making any non 
pre-emptive cash issue pursuant to this resolution which exceeds 7.5% of the Company’s issued share capital in 
any rolling 3 year period.

Resolution 9
The  Sterling  Energy  Plc  Non-executive  Directors  Long-Term  Incentive  Plan  (the  “NED  LTIP”)  was  approved  by 
shareholders at the Extraordinary General Meeting held on 4 December 2009, at which time your Directors were 
authorised to allot shares pursuant to options to be granted under the NED LTIP up to an aggregate nominal 
amount  of  £150,000.  On  30  October  2012,  Keith  Nicholas  Henry,  Nicholas  John  Clayton  and  Malcolm  Hood 
Pattinson  were  each  granted,  subject  to  the  approval  of  shareholders,  an  option  to  acquire  103,150  ordinary 

96

Sterling Energy Plc  Report and Financial Statements 2012shares  at  40p  per  share  (the  “NED  Options”).  The  NED  Options  are  exercisable  after  three  years  and  are  not 
subject  to  performance  conditions.  There  being  insufficient  headroom  within  the  existing  authority  for  issue  of 
shares to satisfy the NED Options, it is proposed that your Directors be authorised to allot shares pursuant to the 
NED Options up to an aggregate nominal amount of £123,780, such authority to expire on 1 October 2017.

Recommendation
Your Directors believe that all the proposed resolutions to be considered at the Annual General Meeting as set 
out in this document are in the best interests of the Company and its shareholders as a whole. Accordingly, your 
Directors unanimously recommend that you vote in favour of them as they intend to do in respect of their own 
beneficial holdings.

Notes:
1. 

Appointment of a Proxy
Only holders of ordinary shares are entitled to attend and vote at this meeting.

A member is entitled to appoint another person as their proxy to exercise all or any of their rights to attend 
to  speak  and  to  vote  at  the  Annual  General  Meeting.  A  member  may  appoint  more  than  one  proxy  in 
relation to the meeting, provided that each proxy is appointed to exercise the rights attached to a different 
share or shares held by them. A proxy need not be a member of the Company. A Form of Proxy for the 
Annual General Meeting is enclosed and should be completed and returned so as to reach the Company’s 
registrar,  Capita  Registrars,  PXS,  34  Beckenham  Road,  Beckenham,  Kent,  BR3  4TU  by  hand,  post  or 
courier (during normal business hours only), not later than 48 hours before the time of the Annual General 
Meeting.  Completion  of  a  Form  of  Proxy  or  any  CREST  Proxy  Instruction  will  not  preclude  a  member 
attending and voting in person at the meeting.

Alternatively,  you  can  register  your  proxy  vote  electronically  by  means  of  a  website  provided  by  the 
Company’s registrar (www.capitashareportal.com), where full instructions are provided. In order to register 
your vote on-line you will need to enter the Investor Code which is given in the enclosed Form of Proxy. This 
website can only be used for the purpose stated above, not for sending any other document or information.

2. 

CREST Electronic Proxies
Alternatively, if you are a member of CREST, you may register the appointment of a proxy by using the 
CREST electronic proxy appointment service.

CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment 
service may do so for this Annual General Meeting and any adjournment(s) thereof by using the procedures 
described in the CREST Manual subject to the provisions of the Company’s Articles of Association. CREST 
personal members or other CREST sponsored members, and those CREST members who have appointed 
a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be 
able to take the appropriate action on their behalf.

In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate 
CREST message (a “CREST Proxy Instruction”) must be properly authenticated in accordance with Euroclear 
UK & Ireland Limited’s specifications and must contain the information required for such instructions, as 
described in the CREST Manual (available via www.euroclear.com/CREST). The message, regardless of 
whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously 
appointed proxy, must, in order to be valid, be transmitted so as to be received by the issuer’s agent (ID 
RA10)  by  no  later  than  48  hours  before  the  start  of  the  Annual  General  Meeting.  For  this  purpose,  the 
time of receipt will be taken to be the time (as determined by the timestamp applied to the message by 
the CREST Applications Host) from which the issuer’s agent is able to retrieve the message by enquiry to

CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed 
through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or voting service providers should note 
that Euroclear UK & Ireland Limited does not make available special procedures in CREST for any particular 
messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy 
Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a 
CREST personal member or sponsored member or has appointed a voting service provider(s), to procure 
that his CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure 
that a message is transmitted by means of the CREST system by any particular time. In this connection, 
CREST members and, where applicable, their CREST sponsors or voting service provider(s) are referred, 
in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system 
and timings.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 
35(5)(a) of the Uncertificated Securities Regulations 2001.
