DISCIPLINED GROWTH

With substantial operating experience in both the Western Canadian Sedimentary basin and the international arena, we 
are committed to generating disciplined value growth. Our ability to allocate capital in a flexible manner has enabled us 
to reliably grow our presence in both well-known and leading-edge plays. We will maintain this approach in 2013 with 
the cost effective expansion of our Horizon Oil Sands project to 250,000 barrels per day of Synthetic Crude Oil (“SCO”). 
Additionally,  we  will  commission  our  40,000  barrel  per  day  Kirby  South  Steam  Assisted  Gravity  Drainage  (“SAGD”) 
project targeted for first steam-in in Q4/13 and advance our deep-water exploratory opportunity in South Africa.

LETTER TO OUR SHAREHOLDERS

We have a proven strategy that works and are focused on effective and efficient operations in all 
areas. Our vast resource base, strong technical expertise and financial resources will facilitate our 
ability to significantly grow free cash flow and maximize returns for our shareholders.

For over twenty years our balanced approach to creating long-term value through the judicious 
development of our diverse long-life assets has proven successful. As a result of our strong, 
disciplined business approach and continued focus on our proven and effective strategy, we remain 
one of the top independents, delivering premium value and defined growth.

Our strategy works. We have the largest proved plus probable reserve base of our peer group with greater 
than 7.8 billion barrels of oil equivalent. Despite our size we remain nimble; able to respond quickly to 
changes in the economic landscape to ensure we can continue to maximize shareholder return. 

In addition to our vast reserve base, we have one of the largest resource bases in our peer group. We 
have  significant  positions  in  thermal  in  situ  crude  oil  and  oil  sands  mining.  In  addition,  we  have  an 
enviable land position in leading edge plays like the Montney and Duvernay. Our large resource base 
provides Canadian Natural with the base to exercise our effective capital allocation strategy to maximize 
value in the near, mid and long-term. We continue to operate with high working interest and leverage 
our dominant land base and infrastructure to maintain effective and efficient operations.

We operate with diligent governance and stewardship throughout our global operations. We recognize 
that a focus on safety in our operations and sustainability in our business model will provide long-term 
benefit to our corporation, the communities in which we operate and our shareholders. Sustainability, 
innovation and minimizing our environmental footprint remain at the forefront of our decision making, 
as we strive for operational excellence. 

We believe in balance. Balance exists throughout our strategy, our portfolio and our business approach. 
We believe in a balanced product mix, producing light crude oil, synthetic crude oil, heavy crude oil and 
natural gas. This balanced approach factors into the many facets of our capital allocation, allowing us to 
prudently  balance  our  resource  development,  dividends,  share  purchases,  strategic  acquisitions  and  
debt repayments. 

Through our fiscal responsibility, disciplined approach and effective capital allocation we have maintained 
a strong balance sheet. Our low debt position allows us to weather fluctuations in the marketplace and 
capture opportunities that become available.

Our achievements this year are as a result of the execution of our proven effective strategy. Our strategy 
combined with our balanced asset base allows us to mitigate market volatility, generate free cash flow 
and maximize returns, while transforming to a longer life, low decline asset base.

Natural Gas

Our 2013 capital allocations to natural gas development are 5% below 2012 levels. This reflects our capital 
allocation discipline, and has resulted in a forecasted 9% reduction in natural gas production levels. Despite 
this, we consider natural gas as an important segment of our commodity mix as we are well positioned to 
respond to any resurgence in natural gas prices. We remain one of the largest producers of natural gas in 
Canada and hold over 16.2 million net acres of land with natural gas potential, including one of Canada’s 
largest  unproven  land  positions  which  we  continue  to  judiciously  manage  and  preserve.  This  prudent 
strategy of efficient and effective development ensures that our cash flow remains strong. Even at today’s 
prices, our natural gas segment continues to generate free cash flow. Our premium land position includes 
one of the industry’s largest exposures to the Montney and Duvernay plays, which have significant value 
potential. Combined with our vast infrastructure and expertise we will be able to leverage our position to 
generate significant value upon price recovery. 

Light Crude Oil and NGLs

In 2012, we continued to grow our Canadian light crude oil production. We drilled 124 wells in 2012, 
which,  in  conjunction  with  enhanced  oil  recovery  activities  and  acquisitions,  resulted  in  13%  annual 
growth of North America light crude oil and NGLs production over 2011 production levels. We have 
significant expertise in the field of light crude oil development and currently operate over 110 waterfloods 
with an additional 22 in the planning phase. We can continue to optimize our land base by leveraging 
new technology. In light crude oil we are maximizing recovery in new and mature pools with enhanced 
oil recovery techniques, horizontal multi-frac technology and infill drilling, while continuing to explore 
for new pool opportunities. With over 500 operated light crude oil pools, we have significant upside 
opportunity to improve oil recovery while maximizing value. 

Natural  gas  liquids  are  an  important  component  to  our  portfolio.  Our  investment  and  operational 
excellence  in  liquids-rich  plays  generates  economic  returns.  In  2013,  we  will  continue  to  delineate 
Montney pool boundaries and drill to maximize returns. Our Montney play at Septimus will continue to 
grow, expanding to 125 million cubic feet of production per day, and increasing to nearly 12,200 barrels 
per day in liquids in 2013. 

International  light  crude  oil  plays  in  the  North  Sea  and  Offshore  Africa  remain  a  core  portion  of  the  
Canadian  Natural  portfolio.  Our  international  opportunities  provide  significant  free  cash  flow,  while 
exposing us to international pricing, and fostering our offshore expertise. Our ability to optimize costs and 
leverage expertise provides a benefit to the Company and its shareholders. Despite the 2011 curtailment 
of the North Sea program as a result of United Kingdom tax restructuring, our strict operating standards 
have ensured those assets still generate free cash flow. In 2013, we intend to drill additional wells on a 
second platform in the North Sea and we will progress Espoir development with an infill drilling program. 
We also expect to progress the partnering process on our high potential block located offshore South Africa 
in 2013, with the objective to conduct an exploratory drilling program in 2014 or 2015.

CANADIAN NATURAL

2012 ANNUAL REPORT

Over the past number of years, Canadian Natural has proactively balanced the allocation of free 
cash  flow  between  resource  development,  dividends,  share  purchases,  acquisitions  and  debt 
repayment. All of these choices have been driven by effective capital allocation and efficient 
operations while maximizing shareholder returns. 

Heavy Crude Oil
Primary

Canadian Natural is the largest primary heavy crude oil producer in 
Canada. In 2012 primary heavy crude oil production grew by 22%, 
versus our budgeted target of 15%. Despite pricing volatility, heavy 
crude oil continues to yield the highest returns in our asset portfolio. 

Our large disciplined drilling programs help to control the capital 
inflationary  pressures,  while  we 
leverage  our  dominant 
infrastructure  to  maintain  effective  and  efficient  operations.  In 
addition  to  our  substantial  infrastructure  and  land  base,  our 
inventory  of  8,500  drilling  locations  allow  us  to  high-grade  our 
capital allocation to deliver consistent, long-term economic returns. 
Primary  heavy  crude  oil  production  volumes  are  targeted  to 
increase 13% in 2013 as we target to drill 890 new wells. This, 
along with technological advancement, will provide us significant 
near term opportunities for production growth. 

Pelican Lake

Our  leading  edge  polymer  flood  at  Pelican  Lake  pool  contains  
4.1 billion barrels of heavy crude oil initially in place and delivered a 
strong response in 2012. A new production facility is currently under 
construction to accommodate production increases at both Pelican 
Lake  and  Woodenhouse.  As  the  polymer  flood  project  expands, 
capital  requirements  will  decline,  increasing  our  free  cash  flow 
generation. We expect to convert 56% of the pool to polymer flood 
by the end of 2013 and target to exit 2013 at 50,000 barrels per day. 

Oil Sands 
Mining and Upgrading

Horizon Oil Sands operations remain focused on safe, steady and 
reliable  production.  We  have  a  world  class  asset  with  over  
3.35  billion  barrels  of  proved  plus  probable  synthetic  crude  oil 
reserves,  representing  decades  of  fully  upgraded  light  crude  oil 
production potential without decline. 

We have made significant progress in operational discipline and 
reliability in 2012. The addition of the third Ore Preparation Plant 
has  enhanced  reliability  significantly  and  allowed  the  effective 
use of intermediate tankage to deliver steady operations in the 
upgrader. We expect reliability to continue to increase in 2013, 
particularly after we complete our first major turnaround.

CANADIAN NATURAL

2012 ANNUAL REPORT

The execution strategy of Phases 2 and 3 at Horizon are delivering 
expected  results  as  we  continue  to  track  below  cost  estimates. 
Phases 2 and 3 are targeting to bring Horizon production levels to 
250,000  barrels  per  day,  with  potential  for  further  expansion  to 
500,000  barrels  per  day.  Production  costs  at  Horizon  are  largely 
fixed; as a result, production costs on a per barrel basis are targeted 
to  reduce  significantly  when  Phases  2  and  3  come  on-stream, 
greatly enhancing the plant’s economics and sustainability. 

Thermal In Situ

With  our  vast  asset  base  and  ability  to  achieve  effective  and 
efficient operations, we are an industry leader in thermal in situ 
operations. At our Primrose field we grew production in 2012 to 
99,000 barrels per day and delivered industry leading per-barrel 
production  costs.  With  attractive  economics  and  a  significant 
drilling inventory, Primrose is expected to add value for decades.

With  an  extensive  inventory  of  thermal  projects,  we  target  to 
grow  production  capacity  to  510,000  barrels  per  day  in  a 
disciplined, stepwise, cost effective approach, adding 40,000 to 
60,000  barrels  per  day  of  incremental  capacity  every  two  to  
three years. 

The  next  step  of  our  thermal  in  situ  growth  plan  is  the  Kirby 
South expansion, which remains on schedule and on budget with 
first  steam  targeted  for  fourth  quarter  2013.  Oil  production  is 
targeted to ramp up to 40,000 barrels per day in late 2014.

In 2012, we strategically added 340 million barrels of contingent 
resource by acquiring lands contiguous to our Kirby development. 
In 2013, we will evaluate the potential to increase the targeted 
Kirby development phases to over 140,000 barrels per day. 

Marketing

We  have  a  long-term  and  effective  heavy  crude  oil  marketing 
strategy  which  maximizes  the  realized  price  for  our  overall 
portfolio regardless of market conditions. This strategy is executed 
under a three-pronged approach to ensure we garner the most 
value. We blend various crude oil streams and diluents to better 
serve  the  needs  of  our  refining  customers.  We  support  the 
expansion  of  pipeline  export  capacity.  And,  finally,  we  support 
and  participate  in  projects  which  add  conversion  capacity  for 
bitumen and synthetic crude oil.

Heavy  crude  oil  differentials  in  2012  averaged  22%,  which  falls 
within our expected long term range of 20-24%. In late 2012 heavy 
crude  oil  differentials  widened  dramatically  as  a  result  of  refinery 
outages and infrastructure constraints. The increase in heavy crude 
oil  conversion  capacity  in  the  US  Midwest  and  the  expansion  of 
existing  transportation  infrastructure  will  again  normalize  these 
differentials. We believe the heavy crude oil differential will return 
to our expected range of 20-24% from West Texas Intermediate 
pricing during the latter half of 2013 and into 2014.

North West Redwater

Additionally,  in  2012  our  Board  of  Directors  sanctioned  the 
Redwater Upgrader/Refinery project, an exciting new facet in our 
diverse portfolio. Combining our strengths with the expertise of 
Northwest Upgrading Inc., we have formed a partnership which 
targets a competitive return on capital. The project targets to add 
50,000  barrels  of  bitumen  conversion  capacity  to  the  market, 
further contributing to improved heavy crude oil pricing.

Our Advantages

Canadian Natural has the largest reserve base in our peer group 
bolstered by an exceptional and diverse asset portfolio capable of 
generating significant free cash flow. In 2012, our total proved 
reserve replacement ratio was 178%, with a total proved reserve 
life index of 22.8 years. Additionally, our year over year proved 
plus probable reserve replacement ratio was 246% for 2012.

(4)  Reserve additions are comprised of all categories of Company Gross reserve changes, exclusive of production.
(5)  Reserve replacement ratio is the Company Gross reserve additions divided by the Company Gross production in the same period.
(6)  A barrel of oil equivalent (“BOE”) is derived by converting six thousand cubic feet of natural gas to one barrel of crude oil (6 Mcf:1 bbl). This conversion may  
be  misleading,  particularly  if  used  in  isolation,  since  the  6  Mcf:1  bbl  ratio  is  based  on  an  energy  equivalency  conversion  method  primarily  applicable  at  the  
burner tip and does not represent a value equivalency at the wellhead. In comparing the value ratio using current crude oil prices relative to natural gas prices, the 
6 Mcf:1 bbl conversion ratio may be misleading as an indication of value.

MANAGEMENT’S DISCUSSION AND ANALYSIS

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements relating to Canadian Natural Resources Limited (the “Company”) in this document or documents incorporated 
herein  by  reference  constitute  forward-looking  statements  or  information  (collectively  referred  to  herein  as  “forward-looking 
statements”) within the meaning of applicable securities legislation. Forward-looking statements can be identified by the words 
“believe”, “anticipate”, “expect”, “plan”, “estimate”, “target”, “continue”, “could”, “intend”, “may”, “potential”, “predict”, 
“should”, “will”, “objective”, “project”, “forecast”, “goal”, “guidance”, “outlook”, “effort”, “seeks”, “schedule”, “proposed” 
or expressions of a similar nature suggesting future outcome or statements regarding an outlook. Disclosure related to expected 
future  commodity  pricing,  forecast  or  anticipated  production  volumes,  royalties,  operating  costs,  capital  expenditures,  income 
tax  expenses  and  other  guidance  provided  throughout  this  Management’s  Discussion  and  Analysis  (“MD&A”)  including  the 
information in the “Outlook” section and the sensitivity analysis constitute forward-looking statements. Disclosure of plans relating 
to and expected results of existing and future developments, including but not limited to the Horizon Oil Sands operations and 
future expansions, Primrose thermal projects, Pelican Lake water and polymer flood project, the Kirby Thermal Oil Sands Project, 
construction of the proposed Keystone XL Pipeline from Hardisty, Alberta to the US Gulf Coast, the proposed Kinder Morgan Trans 
Mountain pipeline expansion from Edmonton, Alberta to Vancouver, British Columbia, and the construction and future operations 
of  the  North  West  Redwater  bitumen  upgrader  and  refinery  also  constitute  forward-looking  statements.  This  forward-looking 
information is based on annual budgets and multi-year forecasts, and is reviewed and revised throughout the year as necessary in 
the context of targeted financial ratios, project returns, product pricing expectations and balance in project risk and time horizons. 
These statements are not guarantees of future performance and are subject to certain risks. The reader should not place undue 
reliance on these forward-looking statements as there can be no assurances that the plans, initiatives or expectations upon which 
they are based will occur. 

In addition, statements relating to “reserves” are deemed to be forward-looking statements as they involve the implied assessment 
based  on  certain  estimates  and  assumptions  that  the  reserves  described  can  be  profitably  produced  in  the  future.  There  are 
numerous uncertainties inherent in estimating quantities of proved and proved plus probable crude oil, natural gas and natural 
gas liquids (“NGLs”) reserves and in projecting future rates of production and the timing of development expenditures. The total 
amount or timing of actual future production may vary significantly from reserve and production estimates. 

The forward-looking statements are based on current expectations, estimates and projections about the Company and the industry 
in which the Company operates, which speak only as of the date such statements were made or as of the date of the report 
or document in which they are contained, and are subject to known and unknown risks and uncertainties that could cause the 
actual results, performance or achievements of the Company to be materially different from any future results, performance or 
achievements  expressed  or  implied  by  such  forward-looking  statements.  Such  risks  and  uncertainties  include,  among  others: 
general economic and business conditions which will, among other things, impact demand for and market prices of the Company’s 
products;  volatility  of  and  assumptions  regarding  crude  oil  and  natural  gas  prices;  fluctuations  in  currency  and  interest  rates; 
assumptions on which the Company’s current guidance is based; economic conditions in the countries and regions in which the 
Company  conducts  business;  political  uncertainty,  including  actions  of  or  against  terrorists,  insurgent  groups  or  other  conflict 
including conflict between states; industry capacity; ability of the Company to implement its business strategy, including exploration 
and development activities; impact of competition; the Company’s defense of lawsuits; availability and cost of seismic, drilling and 
other equipment; ability of the Company and its subsidiaries to complete capital programs; the Company’s and its subsidiaries’ 
ability  to  secure  adequate  transportation  for  its  products;  unexpected  disruptions  or  delays  in  the  resumption  of  the  mining, 
extracting or upgrading of the Company’s bitumen products; potential delays or changes in plans with respect to exploration or 
development projects or capital expenditures; ability of the Company to attract the necessary labour required to build its thermal and 
oil sands mining projects; operating hazards and other difficulties inherent in the exploration for and production and sale of crude 
oil and natural gas and in mining, extracting or upgrading the Company’s bitumen products; availability and cost of financing; the 
Company’s and its subsidiaries’ success of exploration and development activities and their ability to replace and expand crude oil 
and natural gas reserves; timing and success of integrating the business and operations of acquired companies; production levels; 
imprecision of reserve estimates and estimates of recoverable quantities of crude oil, natural gas and NGLs not currently classified 
as  proved;  actions  by  governmental  authorities;  government  regulations  and  the  expenditures  required  to  comply  with  them 
(especially safety and environmental laws and regulations and the impact of climate change initiatives on capital and operating 
costs); asset retirement obligations; the adequacy of the Company’s provision for taxes; and other circumstances affecting revenues 
and expenses. The Company’s operations have been, and in the future may be, affected by political developments and by federal, 
provincial and local laws and regulations such as restrictions on production, changes in taxes, royalties and other amounts payable 
to  governments  or  governmental  agencies,  price  or  gathering  rate  controls  and  environmental  protection  regulations.  Should 

18

CANADIAN NATURAL

2012 ANNUAL REPORT

one  or  more  of  these  risks  or  uncertainties  materialize,  or  should  any  of  the  Company’s  assumptions  prove  incorrect,  actual 
results may vary in material respects from those projected in the forward-looking statements. The impact of any one factor on a 
particular forward-looking statement is not determinable with certainty as such factors are dependent upon other factors, and 
the Company’s course of action would depend upon its assessment of the future considering all information then available. For 
additional information, refer to the “Risks and Uncertainties” section of this MD&A. 

Readers  are  cautioned  that  the  foregoing  list  of  factors  is  not  exhaustive.  Unpredictable  or  unknown  factors  not  discussed  in 
this  report  could  also  have  material  adverse  effects  on  forward-looking  statements.  Although  the  Company  believes  that  the 
expectations conveyed by the forward-looking statements are reasonable based on information available to it on the date such 
forward-looking  statements  are  made,  no  assurances  can  be  given  as  to  future  results,  levels  of  activity  and  achievements.  
All subsequent forward-looking statements, whether written or oral, attributable to the Company or persons acting on its behalf 
are  expressly  qualified  in  their  entirety  by  these  cautionary  statements.  Except  as  required  by  law,  the  Company  assumes  no 
obligation to update forward-looking statements, whether as a result of new information, future events or other factors, or the 
foregoing factors affecting this information, should circumstances or Management’s estimates or opinions change. 

SPECIAL NOTE REGARDING NON-GAAP FINANCIAL MEASURES

This MD&A includes references to financial measures commonly used in the crude oil and natural gas industry, such as adjusted 
net earnings from operations, cash flow from operations, cash production costs and net asset value. These financial measures 
are  not  defined  by  International  Financial  Reporting  Standards  (“IFRS”)  and  therefore  are  referred  to  as  non-GAAP  measures.  
The non-GAAP measures used by the Company may not be comparable to similar measures presented by other companies. The 
Company uses these non-GAAP measures to evaluate  its performance.  The  non-GAAP  measures should  not be considered an 
alternative to or more meaningful than net earnings, as determined in accordance with IFRS, as an indication of the Company’s 
performance. The non-GAAP measures adjusted net earnings from operations and cash flow from operations are reconciled to 
net earnings, as determined in accordance with IFRS, in the “Net Earnings and Cash Flow from Operations” section of this MD&A. 
The derivation of cash production costs is included in the “Operating Highlights – Oil Sands Mining and Upgrading” section of this 
MD&A. The Company also presents certain non-GAAP financial ratios and their derivation in the “Liquidity and Capital Resources” 
section of this MD&A.

MANAGEMENT’S DISCUSSION AND ANALYSIS

This MD&A of the financial condition and results of operations of the Company should be read in conjunction with the Company’s 
audited consolidated financial statements and related notes for the year ended December 31, 2012. 

All  dollar  amounts  are  referenced  in  millions  of  Canadian  dollars,  except  where  noted  otherwise.  Common  share  data  and 
per  common  share  amounts  have  been  restated  to  reflect  the  two-for-one  common  share  split  in  May  2010.  The  Company’s 
consolidated  financial  statements  and  this  MD&A  have  been  prepared  in  accordance  with  IFRS  as  issued  by  the  International 
Accounting  Standards  Board  (“IASB”).  Unless  otherwise  stated,  2010  comparative  figures  have  been  restated  in  accordance  
with IFRS. 

A Barrel of Oil Equivalent (“BOE”) is derived by converting six thousand cubic feet (“Mcf”) of natural gas to one barrel (“bbl”) of 
crude oil (6 Mcf:1 bbl). This conversion may be misleading, particularly if used in isolation, since the 6 Mcf:1 bbl ratio is based on 
an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the 
wellhead. In comparing the value ratio using current crude oil prices relative to natural gas prices, the 6 Mcf:1 bbl conversion ratio 
may be misleading as an indication of value. 

Production  volumes  and  per  unit  statistics  are  presented  throughout  this  MD&A  on  a  “before  royalty”  or  “gross”  basis,  and 
realized prices are net of transportation and blending costs and exclude the effect of risk management activities. Production on an 
“after royalty” or “net” basis is also presented for information purposes only.

OBJECTIVES AND STRATEGY
The Company’s objectives are to increase crude oil and natural gas production, reserves, cash flow and net asset value (1) on a 
per common share basis through the development of its existing crude oil and natural gas properties and through the discovery  
and/or  acquisition  of  new  reserves.  The  Company  strives  to  meet  these  objectives  by  having  a  defined  growth  and  value 
enhancement plan for each of its products and segments. The Company takes a balanced approach to growth and investments 
and focuses on creating long-term shareholder value. The Company allocates its capital by maintaining:

  Balance among its products, namely natural gas, light and medium crude oil and NGLs, Pelican Lake heavy crude oil (2), primary 

heavy crude oil, bitumen (thermal oil) and SCO;

  Balance among near-, mid- and long-term projects; 

  Balance among acquisitions, exploitation and exploration; and

  Balance between sources and terms of debt financing and maintenance of a strong balance sheet.

(1)  Discounted value of crude oil and natural gas reserves plus value of unproved land, less net debt.
(2)  Pelican Lake heavy crude oil is 14–17º API oil, which receives medium quality crude netbacks due to lower production costs and lower royalty rates.

The Company’s three-phase crude oil marketing strategy includes: 

  Blending various crude oil streams with diluents to create more attractive feedstock;

  Supporting and participating in pipeline expansions and/or new additions; and

  Supporting and participating in projects that will increase the downstream conversion capacity for heavy crude oil.

Operational  discipline,  safe,  effective  and  efficient  operations  as  well  as  cost  control  are  fundamental  to  the  Company.  
By  consistently  managing  costs  throughout  all  cycles  of  the  industry,  the  Company  believes  it  will  achieve  continued  growth. 
Effective and efficient operations and cost control are attained by developing area knowledge, and by maintaining high working 
interests and operator status in its properties.

The  Company  is  committed  to  maintaining  a  strong  balance  sheet  and  flexible  capital  structure.  The  Company  believes  it  
has  built  the  necessary  financial  capacity  to  complete  all  of  its  growth  projects.  Additionally,  the  Company’s  risk  management 
hedging  program  reduces  the  risk  of  volatility  in  commodity  prices  and  supports  the  Company’s  cash  flow  for  its  capital  
expenditure programs.

Strategic accretive acquisitions are a key component of the Company’s strategy. The Company has used a combination of internally 
generated cash flows and debt financing to selectively acquire properties generating future cash flows in its core areas.

Highlights for the year ended December 31, 2012 include the following: 

  Achieved net earnings of $1.9 billion, adjusted net earnings from operations of $1.6 billion, and cash flow from operations  

of $6.0 billion;

  Achieved record yearly crude oil and NGLs production of 326,829 bbl/d in the North America – Exploration and Production segment;

  The Company largely maintained its natural gas production levels while strategically reducing its related natural gas capital  

expenditure program;

  Drilled a record 886 net primary heavy crude oil wells;

  The  Company  focuses  on  efficient  and  effective  operations  at  Horizon  and  continues  to  place  emphasis  on  safe,  steady, 

reliable operations;

  Purchased 11,012,700 common shares for a total cost of $318 million under the Normal Course Issuer Bid; and 

Increased annual per share dividend payment to $0.42 from $0.36, the 12th consecutive year of dividend increases.

(1)  The Company’s employee stock option plan provides for a cash payment option. Accordingly, the fair value of the outstanding vested options is recorded as a 
liability on the Company’s balance sheets and periodic changes in the fair value are recognized in net earnings or are capitalized to Oil Sands Mining and Upgrading 
construction costs.

(2)  Derivative  financial  instruments  are  recorded  at  fair  value  on  the  balance  sheets,  with  changes  in  the  fair  value  of  non-designated  hedges  recognized  in  net 
earnings. The amounts ultimately realized may be materially different than reflected in the financial statements due to changes in prices of the underlying items 
hedged, primarily crude oil and natural gas and foreign exchange.

(3)  Unrealized foreign exchange gains and losses result primarily from the translation of US dollar denominated long-term debt to period-end exchange rates, partially 

offset by the impact of cross currency swaps, and are recognized in net earnings.

(4)  During 2012, the Company repaid US$350 million of 5.45% unsecured notes. During 2011, the Company repaid US$400 million of 6.70% unsecured notes.
(5)  All substantively enacted adjustments in applicable income tax rates and other legislative changes are applied to underlying assets and liabilities on the Company’s 
balance sheets in determining deferred income tax assets and liabilities. The impact of these tax rate and other legislative changes is recorded in net earnings during 
the period the legislation is substantively enacted. During 2012, the UK government enacted legislation to restrict the combined corporate and supplementary 
income tax rate relief on UK North Sea decommissioning expenditures to 50%, resulting in an increase in the Company’s deferred income tax liability of $58 million. 
During 2011, the UK government enacted legislation to increase the corporate income tax rate charged on profits from UK North Sea crude oil and natural gas 
production from 50% to 62%, resulting in an increase in the Company’s deferred income tax liability of $104 million. During 2010, changes in Canada to the 
taxation of stock options surrendered by employees for cash payments resulted in a $132 million charge to deferred income tax expense.

For  2012,  the  Company  reported  net  earnings  of  $1,892  million  compared  with  net  earnings  of  $2,643  million  for  2011  
(2010 – $1,673 million). Net earnings for 2012 included net after-tax income of $274 million related to the effects of share-based 
compensation,  risk  management  activities,  fluctuations  in  foreign  exchange  rates,  the  impact  of  a  realized  foreign  exchange 
gain  on  repayment  of  long-term  debt,  and  the  impact  of  statutory  tax  rate  and  other  legislative  changes  on  deferred  income 
tax liabilities (2011 – $103 million after-tax income; 2010 – $771 million after-tax expenses). Excluding these items, adjusted net 
earnings from operations for 2012 decreased to $1,618 million from $2,540 million for 2011 (2010 – $2,444 million).

The decrease in adjusted net earnings for 2012 from 2011 was primarily due to:

lower crude oil and NGLs and natural gas netbacks;

lower realized SCO prices;

  higher depletion, depreciation and amortization expense; and

  higher realized risk management losses;

partially offset by:

  higher crude oil and SCO sales volumes in the North America and Oil Sands Mining and Upgrading segments.

The  impacts  of  share-based  compensation,  risk  management  activities  and  changes  in  foreign  exchange  rates  are  expected  to 
continue to contribute to significant volatility in consolidated net earnings and are discussed in detail in the relevant sections of 
this MD&A.

Cash  flow  from  operations  for  2012  decreased  to  $6,013  million  ($5.48  per  common  share)  from  $6,547  million  
($5.98 per common share) for 2011 (2010 – $6,333 million; $5.82 per common share). The decrease in cash flow from operations 
for 2012 from 2011 was primarily due to the factors noted above relating to the decrease in adjusted net earnings, excluding 
depletion, depreciation and amortization expense, as well as due to the impact of cash taxes.

In the Company’s Exploration and Production activities, the 2012 average sales price per bbl of crude oil and NGLs decreased 9% to 
average $70.24 per bbl from $77.46 per bbl in 2011 (2010 – $65.81 per bbl), and the average natural gas price decreased 35% to 
average $2.44 per Mcf from $3.73 per Mcf in 2011 (2010 – $4.08 per Mcf). The Company’s average sales price of SCO decreased 
11% to average $88.91 per bbl from $99.74 per bbl in 2011 (2010 – $77.89 per bbl).

Total  production  of  crude  oil  and  NGLs  before  royalties  increased  16%  to  451,378  bbl/d  from  389,053  bbl/d  in  2011  
(2010 – 424,985 bbl/d). The increase in crude oil and NGLs production from 2011 was primarily related to additional Horizon production 
volumes and the impact of a strong heavy crude oil drilling program.

Total natural gas production before royalties decreased 3% to average 1,220 MMcf/d from 1,257 MMcf/d in 2011 (2010 – 1,243 MMcf/d).  
The  decrease  in  natural  gas  production  was  primarily  a  result  of  a  strategic  reduction  of  natural  gas  drilling  as  the  Company 
allocated capital to higher return crude oil projects, as well as expected production declines.

Total  crude  oil  and  NGLs  and  natural  gas  production  volumes  before  royalties  increased  9%  to  average  654,665  BOE/d  from 
598,526 BOE/d in 2011 (2010 – 632,191 BOE/d).

Volatility in the quarterly net earnings over the eight most recently completed quarters was primarily due to:

  Crude oil pricing – The impact of fluctuating demand, inventory storage levels and geopolitical uncertainties on worldwide 
benchmark pricing, the impact of the WCS Heavy Differential from WTI in North America and the impact of the differential 
between WTI and Dated Brent benchmark pricing in the North Sea and Offshore Africa.

  Natural gas pricing – The impact of fluctuations in both the demand for natural gas and inventory storage levels, and the 

impact of increased shale gas production in the US.

  Crude oil and NGLs sales volumes – Fluctuations in production due to the cyclic nature of the Company’s Primrose thermal 
projects,  the  results  from  the  Pelican  Lake  water  and  polymer  flood  projects,  the  record  heavy  crude  oil  drilling  program, 
and the impact of the suspension and recommencement of production at Horizon. Sales volumes also reflected fluctuations 
due to timing of liftings and maintenance activities in the North Sea and Offshore Africa, and payout of the Baobab field in  
May 2011. 

  Natural gas sales volumes – Fluctuations in production due to the Company’s strategic decision to reduce natural gas drilling 
activity in North America and the allocation of capital to higher return crude oil projects, as well as natural decline rates,  
shut-in natural gas production due to pricing and the impact and timing of acquisitions.

  Production expense – Fluctuations primarily due to the impact of the demand for services, fluctuations in product mix, the 
impact of seasonal costs that are dependent on weather, production and cost optimizations in North America, acquisitions of 
natural gas producing properties in 2011 that had higher operating costs per Mcf than the Company’s existing properties, and 
the suspension and recommencement of production at Horizon.

  Depletion, depreciation and amortization – Fluctuations due to changes in sales volumes, proved reserves, asset retirement 
obligations, finding and development costs associated with crude oil and natural gas exploration, estimated future costs to 
develop the Company’s proved undeveloped reserves, and the impact of the suspension and recommencement of production 
at Horizon.

  Share-based compensation – Fluctuations due to the determination of fair market value based on the Black-Scholes valuation 

model of the Company’s share-based compensation liability.

  Risk management – Fluctuations due to the recognition of gains and losses from the mark to market and subsequent settlement 

of the Company’s risk management activities.

Foreign  exchange  rates  –  Changes  in  the  Canadian  dollar  relative  to  the  US  dollar  that  impacted  the  realized  price  the 
Company received for its crude oil and natural gas sales, as sales prices are based predominately on US dollar denominated 
benchmarks. Fluctuations in realized and unrealized foreign exchange gains and losses are also recorded with respect to US 
dollar denominated debt, partially offset by the impact of cross currency swap hedges.

Income tax expense – Fluctuations in income tax expense include statutory tax rate and other legislative changes substantively 
enacted in the various periods.

Substantially all of the Company’s production is sold based on US dollar benchmark pricing. Specifically, crude oil is marketed based 
on WTI and Brent indices. Canadian natural gas pricing is primarily based on Alberta AECO reference pricing, which is derived 
from the NYMEX reference pricing and adjusted for its basis or location differential to the NYMEX delivery point at Henry Hub.  
The Company’s realized prices are also highly sensitive to fluctuations in foreign exchange rates. The average value of the Canadian 
dollar in relation to the US dollar fluctuated significantly throughout 2012, with a high of approximately US$1.03 in September 
2012 and a low of approximately US$0.96 in June 2012.

WTI pricing in 2012 was reflective of the political instability in the Middle East, the declining optimism in the United States economy 
related to the fiscal cliff, the European debt crisis, and lower than expected growth in Asian demand. For 2012, WTI averaged 
US$94.19 per bbl and was comparable with 2011 (2010 – US$79.55 per bbl). 

Brent averaged US$111.56 per bbl for 2012 and was comparable with 2011 (2010 – US$79.50 per bbl). Crude oil sales contracts 
for the North Sea and Offshore Africa are typically based on Brent pricing, which is representative of international markets and 
overall  world  supply  and  demand.  The  higher  Brent  pricing  relative  to  WTI  in  2012  was  due  to  logistical  constraints  and  high 
inventory levels of crude oil at Cushing. 

The WCS Heavy Differential averaged 22% for 2012 compared with 18% for 2011 and 2010. The WCS Heavy Differential widened 
from the comparable periods as a result of planned and unplanned pipeline outages to key Canadian crude oil markets. The impact 
of higher WCS Heavy Differentials in January and February 2013 of 35% and 39% respectively were partially offset by higher 
overall WTI benchmark pricing. The WCS Heavy Differential narrowed in March 2013 to average approximately 29%. 

The Company uses condensate as a blending diluent for heavy crude oil pipeline shipments. During 2012 and the comparable 
periods, condensate prices traded at a premium to WTI and reflected normal seasonal pricing adjustments.

The  Company  anticipates  continued  volatility  in  crude  oil  pricing  benchmarks  due  to  supply  and  demand  factors,  geopolitical 
events, and the timing and extent of the economic recovery. The WCS Heavy Differential is expected to continue to reflect seasonal 
demand fluctuations, changes in transportation logistics, and refinery utilization and shutdowns.

NYMEX  natural  gas  prices  averaged  US$2.80  per  MMBtu  for  2012,  a  decrease  of  31%  from  US$4.07  per  MMBtu  for  2011  
(2010 – US$4.42 per MMBtu). AECO natural gas pricing averaged $2.28 per GJ for 2012, a decrease of 34% from US$3.48 per GJ 
for 2011 (2010 – $3.91 per GJ). While Canadian production has declined in response to low prices, US production has held steady 
during 2012. Natural gas pricing continues to be volatile as the market still requires a shift to higher utilization of gas fired electric 
generation to offset the strong North America supply position.

Operating and Capital Costs

Strong crude oil commodity prices in recent years have resulted in increased demand for oilfield services worldwide. This has led to 
inflationary operating and capital cost pressures, particularly related to drilling activities and oil sands developments.

Continued cost pressures and the final outcome of changes to environmental regulations may adversely impact the Company’s

Revenue increased 4% to $16,195 million for 2012 from $15,507 million for 2011 (2010 – $14,322 million). The increase was 
primarily due to higher crude oil and SCO volumes in North America and Oil Sands Mining and Upgrading segments, partially offset 
by a decrease in realized North America crude oil and NGLs and natural gas prices, Oil Sands Mining and Upgrading SCO prices, 
and lower International production.

For  2012,  11%  of  the  Company’s  crude  oil  and  natural  gas  revenue  was  generated  outside  of  North  America  
(2011 – 14%; 2010 – 13%). North Sea accounted for 6% of crude oil and natural gas revenue for 2012 (2011 – 8%; 2010 – 7%), 
and Offshore Africa accounted for 5% of crude oil and natural gas revenue for 2012 (2011 – 6%; 2010 – 6%).

The  Company’s  business  approach  is  to  maintain  large  project  inventories  and  production  diversification  among  each  of  the 
commodities it produces; namely natural gas, light and medium crude oil and NGLs, Pelican Lake heavy crude oil, primary heavy 
crude oil, bitumen (thermal oil), and SCO.

Total 2012 production averaged 654,665 BOE/d, a 9% increase from 598,526 BOE/d in 2011 (2010 – 632,191 BOE/d).

Total production of crude oil and NGLs before royalties increased 16% to 451,378 bbl/d for 2012 from 389,053 bbl/d in 2011 
(2010 – 424,985 bbl/d). The increase in crude oil and NGLs production from 2011 was primarily related to additional Horizon 
production volumes and the impact of a strong heavy crude oil drilling program. Crude oil and NGLs production for 2012 was 
slightly below the Company’s previously issued guidance of 452,000 to 460,000 bbl/d.

Natural gas production continued to represent the Company’s largest product offering, accounting for 31% of the Company’s 
total production in 2012 on a BOE basis. Total natural gas production before royalties decreased 3% to 1,220 MMcf/d for 2012 
from 1,257 MMcf/d for 2011 (2010 – 1,243 MMcf/d). The decrease in natural gas production from 2011 was primarily a result 
of  a  strategic  reduction  of  natural  gas  drilling  as  the  Company  allocated  capital  to  higher  return  crude  oil  projects,  as  well  as 
expected production declines. Natural gas production for 2012 was slightly below the Company’s previously issued guidance of  
1,222 to 1,229 MMcf/d.

North America – Exploration and Production

North America crude oil and NGLs production for 2012 increased 11% to average 326,829 bbl/d from 295,618 bbl/d for 2011 
(2010  –  270,562  bbl/d).  The  increase  in  production  from  2011  was  primarily  due  to  the  impact  of  a  strong  heavy  crude  oil  
drilling program.

North  America  natural  gas  production  for  2012  decreased  3%  to  average  1,198  MMcf/d  from  1,231  MMcf/d  in  2011  
(2010 – 1,217 MMcf/d). The decrease in natural gas production from 2011 was primarily a result of a strategic reduction of natural 
gas drilling as the Company allocated capital to higher return crude oil projects, as well as expected production declines. 

North America – Oil Sands Mining and Upgrading

Production averaged 86,077 bbl/d for 2012 compared with 40,434 bbl/d for 2011 (2010 – 90,867 bbl/d). Production in 2012 
reflected the impact of unplanned maintenance on the fractionator in the Horizon primary upgrading facility. 

North Sea

North Sea crude oil production for 2012 was 19,824 bbl/d, a decrease of 34% from 29,992 bbl/d for 2011 (2010 – 33,292 bbl/d). 
The decrease in production volumes from 2011 was primarily due to temporary shut ins of the third-party operated pipeline to 
Sullom Voe, which caused all Ninian and associated fields to be shut in for a portion of the third and fourth quarters of 2012, the 
suspension of production at Banff/Kyle, and natural field declines. 

In December 2011, the Banff FPSO and subsea infrastructure suffered storm damage. Operations at Banff/Kyle, with combined net 
production of approximately 3,500 bbl/d, were suspended. The FPSO and associated floating storage unit have subsequently been 
removed from the field and the FPSO is currently in dry dock for assessment of damages and repair timeframe. The extent of the 
property damage, including associated costs, is not expected to be significant. 

Offshore Africa

Offshore Africa crude oil production for 2012 decreased 19% to 18,648 bbl/d from 23,009 bbl/d for 2011 (2010 – 30,264 bbl/d) 
due to natural field declines, planned turnaround activity, and the shut in of approximately 1,500 bbl/d of production at the Olowi 
field, Gabon. The Company currently has a vessel on-site in Gabon assessing the operability of the midwater arch. 

Guidance

The Company targets production levels in 2013 to average between 482,000 bbl/d and 513,000 bbl/d of crude oil and NGLs and 
between 1,085 MMcf/d and 1,145 MMcf/d of natural gas.

CRUDE OIL INVENTORY VOLUMES
The Company recognizes revenue on its crude oil production when title transfers to the customer and delivery has taken place. 
Revenue has not been recognized on crude oil volumes that were stored in various tanks, pipelines, or FPSOs, as follows:

(2010 – $62.28 per bbl). The decrease in 2012 was primarily a result of the lower WTI benchmark pricing and the widening of the 
WCS Heavy Differential, partially offset by the impact of a weaker Canadian dollar relative to the US dollar. 

North  America  realized  natural  gas  prices  decreased  37%  to  average  $2.31  per  Mcf  for  2012  from  $3.64  per  Mcf  for  2011  
(2010 – $4.05 per Mcf), primarily due to lower NYMEX and AECO benchmark pricing related to the impact of strong supply from 
US shale projects.

The Company continues to focus on its crude oil marketing strategy including a blending strategy that expands markets within 
current pipeline infrastructure, supporting pipeline projects that will provide capacity to transport crude oil to new markets, and 
working with refiners to add incremental heavy crude oil conversion capacity. During 2012, the Company contributed approximately 
157,000 bbl/d of heavy crude oil blends to the WCS stream. The Company has entered into a 20 year transportation agreement 
to ship 120,000 bbl/d of heavy crude oil on the proposed Keystone XL Pipeline from Hardisty, Alberta to the US Gulf Coast. The 
Company also entered into a 20 year crude oil purchase and sales agreement to sell 100,000 bbl/d of heavy crude oil to a major US 
refiner. The construction of the Keystone XL Pipeline is dependent on a Presidential Permit. During 2012, the Company entered into 
a 20 year transportation agreement to ship 75,000 bbl/d of crude oil on the proposed Kinder Morgan Trans Mountain Expansion 
from  Edmonton,  Alberta  to  Vancouver,  British  Columbia.  The  regulatory  approval  process  will  begin  in  2013  with  a  planned

North America

Government royalties on a significant portion of North America crude oil and NGLs production fall under the oil sands royalty 
regime and are calculated on a project by project basis as a percentage of gross revenue less operating, capital and abandonment 
costs (“net profit”). 

Crude oil and NGLs royalties averaged approximately 16% of product sales in 2012 compared with 19% in 2011 (2010 – 19%) 
primarily due to lower WTI benchmark pricing and changes in the WCS Heavy Differential. North America crude oil and NGLs 
royalties per bbl are anticipated to average 16% to 18% of product sales for 2013.

Natural gas royalties averaged approximately 3% of product sales for 2012 compared with 4% in 2011 (2010 – 5%) primarily due 
to lower realized natural gas prices. North America natural gas royalties per Mcf are anticipated to average 4% to 6% of product 
sales for 2013.

North Sea

North Sea government royalties on crude oil were eliminated effective January 1, 2003. The remaining royalty is a gross overriding 
royalty on the Ninian field. 

Offshore Africa

Under the terms of the various Production Sharing Contracts, royalty rates fluctuate based on realized commodity pricing, capital 
and operating costs, the status of payouts, and the timing of liftings from each field. 

Royalty rates as a percentage of product sales averaged approximately 26% for 2012 compared to 17% for 2011 (2010 – 7%) 
primarily due to higher crude oil prices, adjustments to royalties on liftings, and the payout of the Baobab field in May 2011. 
Offshore Africa royalty rates are anticipated to average 9% to 11% of product sales for 2013.

North  America  crude  oil  and  NGLs  production  expense  for  2012  averaged  $13.40  per  bbl  and  was  comparable  with  2011  
(2010 – $12.14 per bbl). North America crude oil and NGLs production expense is anticipated to average $12.00 to $14.00 per 
bbl for 2013.

North  America  natural  gas  production  expense  for  2012  increased  14%  to  $1.28  per  Mcf  from  $1.12  per  Mcf  for  2011  
(2010 – $1.06 per Mcf). Natural gas production expense increased from 2011 due to the impact of lower production volumes 
related  to  the  shut  in  of  production  and  the  curtailment  of  capital  expenditures  related  to  natural  gas  activity.  North  America 
natural gas production expense is anticipated to average $1.30 to $1.40 per Mcf for 2013 due to natural declines.

North Sea

North  Sea  crude  oil  production  expense  for  2012  increased  44%  to  $53.53  per  bbl  from  $37.06  per  bbl  for  2011  
(2010 – $29.73 per bbl). Production expense increased on a per bbl basis due to the impact of production declines on relatively 
fixed  costs,  temporary  shut  ins  of  the  third-party  operated  pipeline  to  Sullom  Voe,  and  higher  maintenance  costs  related  to 
turnaround activity in 2012. North Sea crude oil production expense is anticipated to average $62.00 to $66.00 per bbl for 2013 
due to natural declines on a relatively fixed cost structure.

Offshore Africa

Offshore  Africa  crude  oil  production  expense  for  2012  increased  12%  to  $23.11  per  bbl  from  $20.72  per  bbl  for  2011  
(2010 – $14.64 per bbl). Production expense increased due to the timing of liftings from various fields, which have different cost 
structures. Offshore Africa crude oil production expense is anticipated to average $33.50 to $37.50 per bbl for 2013 due to timing 
of liftings from various fields.

OPERATING HIGHLIGHTS – OIL SANDS MINING AND UPGRADING
Operations Update

During 2012, the Company continued to focus on efficient and effective operations at Horizon and place emphasis on safe, steady, 
reliable operations. Production in 2012 reflected the impact of unplanned maintenance on the fractionator in the Horizon primary 
upgrading facility. 

In the second quarter of 2013, Horizon will enter into a 24 day planned maintenance turnaround, resulting in a plant-wide shut down. The 
impact of the turnaround has been reflected in the Company’s 2013 production, cash production cost and capital expenditure guidance.

The  Company’s  midstream  assets  include  three  crude  oil  pipeline  systems  and  a  50%  working  interest  in  an  84-megawatt 
cogeneration plant at Primrose. Approximately 80% of the Company’s heavy crude oil production is transported to international 
mainline liquid pipelines via the 100% owned and operated ECHO Pipeline, the 62% owned and operated Pelican Lake Pipeline 
and the 15% owned Cold Lake Pipeline. The midstream pipeline assets allow the Company to control the transport of a portion 
of its own production volumes as well as earn third party revenue. This transportation control enhances the Company’s ability to 
manage the full range of costs associated with the development and marketing of its heavier crude oil.

In 2011, the Company announced that it had entered into a partnership agreement with North West Upgrading Inc. to move 
forward with detailed engineering regarding the construction and operation of a bitumen upgrader and refinery (“the Project”) 
near Redwater, Alberta. In addition, the partnership entered into processing agreements that target to process bitumen for the 
Company and the Alberta Petroleum Marketing Commission (“APMC”), an agent of the Government of Alberta, under a 30 year 
fee-for-service tolling agreement under the Bitumen Royalty In Kind initiative. In 2012, the Project was sanctioned by the Board 
of Directors of each partner of the North West Redwater Partnership (“Redwater”), and the associated target toll amounts were 
accepted by Redwater, the Company and the APMC.

The Company’s stock option plan provides current employees with the right to receive common shares or a direct cash payment in 
exchange for stock options surrendered.

The share-based compensation liability at December 31, 2012 reflected the Company’s liability for awards granted to employees at 
fair value estimated using the Black-Scholes valuation model. In periods when substantial share price changes occur, the Company’s 
net  earnings  are  subject  to  significant  volatility.  The  Company  utilizes  its  share-based  compensation  plan  to  attract  and  retain 
employees in a competitive environment. All employees participate in this plan.

The  Company  recorded  a  $214  million  share-based  compensation  recovery  for  the  year  ended  December  31,  2012,  primarily 
as  a  result  of  remeasurement  of  the  fair  value  of  outstanding  stock  options  at  the  end  of  the  year  related  to  a  decrease  in 
the  Company’s  share  price,  partially  offset  by  normal  course  graded  vesting  of  stock  options  granted  in  prior  periods  and  the 
impact of vested stock options exercised or surrendered during the year. For the year ended December 31, 2012, a $12 million  
recovery was recognized in respect of capitalized share-based compensation to Oil Sands Mining and Upgrading (2011 – $nil; 
2010 – $32 million expense capitalized). 

During 2012, the Company paid $7 million for stock options surrendered for cash payments (2011 – $14 million; 2010 – $45 million).

During 2012, realized risk management losses primarily related to the settlement of crude oil and foreign currency contracts. The 
Company recorded a net unrealized gain of $42 million ($37 million after-tax) on its risk management activities (2011 – $128 million  
unrealized gain, $95 million after-tax; 2010 – $24 million unrealized gain, $16 million after-tax), related to changes in the fair value 
of these contracts.

The cash settlement amount of commodity derivative financial instruments may vary materially depending upon the underlying 
crude oil prices at the time of final settlement, as compared to their fair value at December 31, 2012.

The Company’s operating results are affected by the fluctuations in the exchange rates between the Canadian dollar, US dollar, 
and  UK  pound  sterling.  Predominantly  all  of  the  Company’s  revenue  is  based  on  reference  to  US  dollar  benchmark  prices.  An 
increase in the value of the Canadian dollar in relation to the US dollar results in decreased revenue from the sale of the Company’s 
production. Conversely a decrease in the value of the Canadian dollar in relation to the US dollar results in increased revenue from 
the sale of the Company’s production. Production expenses in the North Sea are subject to foreign currency fluctuations due to 
changes in the exchange rate of the UK pound sterling to the US dollar. The value of the Company’s US dollar denominated debt 
is also impacted by the value of the Canadian dollar in relation to the US dollar. 

The net realized foreign exchange gain for 2012 was primarily due to the repayment of US$350 million of 5.45% unsecured notes, 
together with the impact of foreign exchange rate fluctuations on settlement of working capital items denominated in US dollars 
or UK pounds sterling. The net unrealized foreign exchange loss in 2012 was primarily related to the reversal of the life-to-date 
unrealized foreign exchange gain on the repayment of US$350 million of 5.45% unsecured notes; partially offset by the impact 
of the strengthening of the Canadian dollar at December 31, 2012 with respect to remaining US dollar debt. Included in the net 
unrealized loss for 2012 was an unrealized loss of $53 million (2011 – $42 million unrealized gain, 2010 – $101 million unrealized 
loss) related to the impact of cross currency swaps. The US/Canadian dollar exchange rate ended the year at US$1.0051 compared 
with US$0.9833 at December 31, 2011 (December 31, 2010 – US$1.0054).

During 2012, the UK government enacted legislation to restrict the combined corporate and supplementary income tax relief on 
UK North Sea decommissioning expenditures to 50%. As a result of the income tax rate change, the Company’s deferred income 
tax liability was increased by $58 million. 

During 2011, the UK government enacted legislation to increase the supplementary income tax rate charged on profits from UK 
North Sea crude oil and natural gas production, increasing the combined corporate and supplementary income tax rate from 50% 
to 62%. As a result of the income tax rate change, the Company’s deferred income tax liability was increased by $104 million. 

During 2011, the Canadian federal government enacted legislation to implement several taxation changes. These changes include 
a requirement that, beginning in 2012, partnership income must be included in the taxable income of each corporate partner 
based on the tax year of the partner, rather than the fiscal year of the partnership. The legislation includes a five-year transition 
provision and has no impact on net earnings. 

During 2010, deferred income tax expense included a charge of $132 million related to enacted changes in Canada to the taxation 
of stock options surrendered by employees for cash.

The Company files income tax returns in the various jurisdictions in which it operates. These tax returns are subject to periodic 
examinations in the normal course by the applicable tax authorities. The tax returns as prepared may include filing positions that 
could be subject to differing interpretations of applicable tax laws and regulations, which may take several years to resolve. The 
Company does not believe the ultimate resolution of these matters will have a material impact upon the Company’s results of 
operations, financial position or liquidity.

During  2012,  the  Company  filed  Scientific  Research  and  Experimental  Development  claims  of  approximately  $300  million  
(2011 – $210 million, 2010 – $190 million) relating to qualifying research and development capital and operating expenditures for 
Canadian income tax purposes.

For 2013, based on budgeted prices and the current availability of tax pools, the Company expects to incur current income tax 
expense of $550 million to $650 million in Canada and $10 million to $100 million in the North Sea and Offshore Africa.

(1)  Net capital expenditures exclude adjustments related to differences between carrying amounts and tax values, and other fair value adjustments.
(2)  Capitalized interest and other includes expenditures related to land acquisition and retention, seismic, and other adjustments.
(3)  During 2011, the Company recognized $393 million of property damage insurance recoveries (see note 10 to the Company’s consolidated financial statements), 

offsetting the costs incurred related to the coker rebuild and collateral damage costs.

(4)  Abandonments represent expenditures to settle asset retirement obligations and have been reflected as capital expenditures in this table.

The  Company’s  strategy  is  focused  on  building  a  diversified  asset  base  that  is  balanced  among  various  products.  In  order  to 
facilitate efficient operations, the Company concentrates its activities in core areas. The Company focuses on maintaining its land 
inventories to enable the continuous exploitation of play types and geological trends, greatly reducing overall exploration risk.  
By owning associated infrastructure, the Company is able to maximize utilization of its production facilities, thereby increasing 
control over production costs.

Net  capital  expenditures  for  2012  were  $6,308  million  compared  with  $6,414  million  for  2011  (2010  –  $5,514  million).  The 
increase in 2012 capital expenditures in the Exploration and Production and Oil Sands Mining and Upgrading segments from 2011 
was primarily due to an increase in production and related facilities spending, partially offset by lower net property acquisition 
costs, and the ramp up of Horizon site construction activity.

North America, excluding Oil Sands Mining and Upgrading, accounted for approximately 69% of the total capital expenditures for 
2012 compared to approximately 77% for 2011 (2010 – 83%).

During 2012, the Company targeted 35 net natural gas wells, including 15 wells in Northeast British Columbia and 20 wells in Northwest 
Alberta. The Company also targeted 1,236 net crude oil wells. The majority of these wells were concentrated in the Company’s Northern 
Plains region where 886 primary heavy crude oil wells, 65 Pelican Lake heavy crude oil wells, 8 light crude oil wells and 161 bitumen 
(thermal oil) wells were drilled. Another 116 wells targeting light crude oil were drilled outside the Northern Plains region.

The Company continued to access its large crude oil drilling inventory to maximize value in both the short and long term. Due to 
the Company’s focus on drilling crude oil wells in recent years and low natural gas prices, natural gas drilling activities have been 
reduced. Deferred natural gas well locations have been retained in the Company’s prospect inventory.

As part of the phased expansion of its thermal in situ Oil Sands assets, the Company is continuing to develop its Primrose thermal 
projects. During 2012, the Company drilled 135 bitumen (thermal oil) wells, and 105 stratigraphic test wells and observation wells. 
Overall Primrose thermal production for 2012 averaged approximately 99,000 bbl/d, compared with approximately 98,000 bbl/d 
in 2011 (2010 – 90,000 bbl/d). Production volumes were in line with expectations due to the cyclic nature of thermal production 
at Primrose. Additional pad drilling was completed and drilled on budget, with these wells coming on production in 2013.

The next planned phase of the Company’s thermal in situ Oil Sands assets expansion is the Kirby South Phase 1 Project. As at  
December 31, 2012, the overall project was 81% complete, drilling was completed on the fifth of seven pads, and first steam is 
targeted for late 2013. In 2012, the Company acquired approximately 49 sections (12,630 hectares) of additional Oil Sands rights 
immediately adjacent to the Kirby Project. 

The  Company  continued  to  develop  the  tertiary  recovery  conversion  projects  at  Pelican  Lake  throughout  2012.  Pelican  Lake 
production averaged approximately 38,000 bbl/d in 2012 (2011 – 38,000 bbl/d; 2010 – 38,000 bbl/d). The completion of the new 
20,000 bbl/d battery expansion is targeted to be on stream in the second quarter of 2013. With this incremental capacity, both 
Woodenhouse and Pelican production volumes will no longer be restricted.

For 2013, the Company’s overall drilling activity in North America is expected to be 1,022 net crude oil wells, 132 net bitumen  
wells and 30 net natural gas wells, excluding stratigraphic and service wells. 

Oil Sands Mining and Upgrading

Phase 2/3 expansion activity during 2012 was focused on the field construction of the gas recovery unit, sulphur recovery unit, 
butane treatment unit, tank farms, coker expansion, hydrotransport, tailings, and extraction trains 3 and 4, along with engineering 
related  to  the  hydrogen,  utilities,  hydrotreater,  vacuum  distillation  and  diluent  recovery  units,  and  permanent  camp.  Final 
commissioning of the third ore preparation plant and associated hydro-transport was completed in January 2012. 

North Sea

In December 2011, the Banff FPSO and subsea infrastructure suffered storm damage. Operations at Banff/Kyle, with combined net 
production of approximately 3,500 bbl/d, were suspended. The FPSO and associated floating storage unit have subsequently been 
removed from the field and the FPSO is currently in dry dock for assessment of the damage and repair timeframe. The extent of 
the property damage, including associated costs, is not expected to be significant. 

In 2012, the UK government announced the implementation of the Brownfield Allowance, which allows for an agreed allowance 
related  to  property  development  for  certain  pre-approved  qualifying  field  developments.  This  allowance  partially  mitigates  the 
impact of previous tax increases. The Company is currently assessing the impact of this initiative on its future capital programs.

The Company currently plans to decommission the Murchison platform in the North Sea commencing in 2014 and estimates the 
decommissioning efforts will continue for approximately 5 years.

At December 31, 2012, the Company’s capital resources consisted primarily of cash flow from operations, available bank credit 
facilities and access to debt capital markets. Cash flow from operations and the Company’s ability to renew existing bank credit 
facilities and raise new debt is dependent on factors discussed in the “Risks and Uncertainties” section of this MD&A. In addition, 
the Company’s ability to renew existing bank credit facilities and raise new debt is also dependent upon maintaining an investment 
grade debt rating and the condition of capital and credit markets. The Company continues to believe that its internally generated 
cash flow from operations supported by the implementation of its ongoing hedge policy, the flexibility of its capital expenditure 
programs supported by its multi-year financial plans, its existing bank credit facilities, and its ability to raise new debt on commercially 
acceptable  terms  will  provide  sufficient  liquidity  to  sustain  its  operations  in  the  short,  medium  and  long  term  and  support  its 
growth strategy. At December 31, 2012, the Company had $3,661 million of available credit under its bank credit facilities. 

During  2012,  the  Company’s  $1,500  million  revolving  syndicated  credit  facility  was  extended  to  June  2016.  Additionally,  the 
Company issued $500 million of 3.05% medium-term notes due June 2019. Proceeds from the securities issued were used to 
repay  bank  indebtedness  and  for  general  corporate  purposes.  After  issuing  these  securities,  the  Company  has  $2,500  million 
remaining on its outstanding $3,000 million base shelf prospectus that allows for the issue of medium-term notes in Canada, 
which expires in November 2013. If issued, these securities will bear interest as determined at the date of issuance.

During 2012, the Company repaid US$350 million of 5.45% unsecured notes. The Company has US$2,000 million remaining on 
its outstanding US$3,000 million base shelf prospectus that allows for the issue of US dollar debt securities in the United States, 
which expires in November 2013. If issued, these securities will bear interest as determined at the date of issuance. 

Subsequent to December 31, 2012, $400 million of 4.50% medium-term notes and US$400 million of 5.15% unsecured notes 
were repaid. This indebtedness was retired utilizing cash flow from operations generated in excess of capital expenditures and 
available  bank  credit  facilities  as  necessary,  while  maintaining  the  ongoing  dividend  program.  On  a  pro  forma  basis,  reflecting 
the retirement of this indebtedness at December 31, 2012, the available credit under its bank credit facilities would amount to  
$2,863 million.

CANADIAN NATURAL

2012 ANNUAL REPORT

Long-term  debt  was  $8,736  million  at  December  31,  2012,  resulting  in  a  debt  to  book  capitalization  ratio  of  26%  
(December 31, 2011 – 27%; December 31, 2010 – 29%). This ratio is within the 25% to 45% internal range utilized by management. 
This range may be exceeded in periods when a combination of capital projects, acquisitions, or lower commodity prices occurs. The 
Company may be below the low end of the targeted range when cash flow from operations is greater than current investment 
activities. The Company remains committed to maintaining a strong balance sheet, adequate available liquidity and a flexible capital 
structure. The Company has hedged a portion of its crude oil production for 2013 at prices that protect investment returns to ensure 
ongoing balance sheet strength and the completion of its capital expenditure programs. Further details related to the Company’s long-
term debt at December 31, 2012 are discussed in note 8 to the Company’s consolidated financial statements.

The Company’s commodity hedge policy reduces the risk of volatility in commodity prices and supports the Company’s cash flow 
for its capital expenditure programs. This policy currently allows for the hedging of up to 60% of the near 12 months budgeted 
production and up to 40% of the following 13 to 24 months estimated production. For the purpose of this policy, the purchase 
of put options is in addition to the above parameters. As at March 6, 2013, approximately 48% of currently forecasted 2013 
crude oil volumes were hedged using price collars. Further details related to the Company’s commodity related derivative financial 
instruments outstanding at December 31, 2012 are discussed in note 17 to the Company’s consolidated financial statements.

Share Capital

As at December 31, 2012, there were 1,092,072,000 common shares outstanding and 73,747,000 stock options outstanding. 
As at March 5, 2013, the Company had 1,092,589,000 common shares outstanding and 68,482,000 stock options outstanding.

During 2012, the Company amended its Articles by special resolution of the shareholders, changing the designation of its Class 
1 preferred shares to “Preferred Shares” which may be issuable in series. If issued, the number of shares in each series, and the 
designation, rights, privileges, restrictions and conditions attached to the shares will be determined by the Board of Directors of 
the Company.

On March 6, 2013, the Company’s Board of Directors approved an increase in the annual dividend to be paid by the Company to 
$0.50 per common share for 2013. The increase represents an approximately 19% increase from 2012, recognizing the stability of 
the Company’s cash flow and providing a return to shareholders. The dividend policy undergoes periodic review by the Board of 
Directors and is subject to change. In March 2012, an increase in the annual dividend paid by the Company to $0.42 per common 
share was approved for 2012. The increase represented a 17% increase from 2011.

In 2012, the Company announced a Normal Course Issuer Bid to purchase, through the facilities of the TSX and the NYSE, during 
the  twelve  month  period  commencing  April  2012  and  ending  April  2013,  up  to  55,027,447  common  shares.  The  Company’s 
Normal Course Issuer Bid announced in 2011 expired April 2012.

During 2012, the Company purchased for cancellation 11,012,700 common shares at a weighted average price of $28.91 per 
common share for a total cost of $318 million.

In addition to the commitments disclosed above, the Company has entered into various agreements related to the engineering, 
procurement and construction of subsequent phases of Horizon. These contracts can be cancelled by the Company upon notice 
without penalty, subject to the costs incurred up to and in respect of the cancellation.

LEGAL PROCEEDINGS AND OTHER CONTINGENCIES

The Company is a defendant and plaintiff in a number of legal actions arising in the normal course of business. In addition, the 
Company is subject to certain contractor construction claims. The Company believes that any liabilities that might arise pertaining 
to any such matters would not have a material effect on its consolidated financial position. 

RESERVES

For the years ended December 31, 2012, 2011 and 2010, the Company retained Independent Qualified Reserves Evaluators to 
evaluate and review all of the Company’s proved and proved plus probable crude oil, NGLs and natural gas reserves. The evaluation 
and  review  was  conducted  in  accordance  with  the  standards  contained  in  the  Canadian  Oil  and  Gas  Evaluation  Handbook  
(“COGE  Handbook”)  and  disclosed  in  accordance  with  National  Instrument  51-101  –  Standards  of  Disclosure  for  Oil  and  
Gas Activities (“NI 51-101“) requirements. In previous years, the Company was granted an exemption from certain provisions of 
NI 51-101 allowing the Company to substitute SEC requirements under Regulations S-K and S-X for certain disclosures required 
under NI 51-101. Such exemption expired on December 31, 2010.

The Company annually discloses net proved reserves and the standardized measure of discounted future net cash flows using 
12-month average prices and current costs in accordance with United States FASB Topic 932 “Extractive Activities - Oil and Gas”  
in  the  Company’s  annual  Form  40-F  filed  with  the  SEC  and  in  the  “Supplementary  Oil  and  Gas  Information”  section  of  the 
Company’s Annual Report.

At December 31, 2012, the company gross proved crude oil, bitumen, SCO and NGLs reserves totaled 4,329 MMbbl, and gross 
proved plus probable crude oil, bitumen, SCO and NGLs reserves totaled 6,921 MMbbl. Proved reserve additions and revisions 
replaced 245% of 2012 production. Additions to proved reserves resulting from exploration and development activities, acquisitions 
and future offset additions amounted to 143 MMbbl, and additions to proved plus probable reserves amounted to 460 MMbbl. 
Net positive revisions amounted to 261 MMbbl for proved reserves and 105 MMbbl for proved plus probable reserves, primarily 
due to technical revisions to prior estimates based on improved or better than expected reservoir performance.

At December 31, 2012, the company gross proved natural gas reserves totaled 4,136 Bcf, and gross proved plus probable natural gas 
reserves totaled 5,787 Bcf. Proved reserve additions and revisions replaced 30% of 2012 production. Additions to proved reserves 
resulting from exploration and development activities, acquisitions and future offset additions amounted to 116 Bcf, and additions to 
proved plus probable reserves amounted to 182 Bcf. Net positive revisions amounted to 19 Bcf for proved reserves and net negative 
revisions amounted to 50 Bcf for proved plus probable reserves, primarily due to lower estimated future benchmark pricing.

The Reserves Committee of the Company’s Board of Directors has met with and carried out independent due diligence procedures 
with each of the Company’s Independent Qualified Reserves Evaluators to review the qualifications of and procedures used by 
each evaluator in determining the estimate of the Company’s quantities and related net present value of future net revenue of the 
remaining reserves. 

Additional reserves disclosure is annually disclosed in the AIF and the “Supplementary Oil and Gas Information” section of the

RISKS AND UNCERTAINTIES

The Company is exposed to various operational risks inherent in the exploration, development, production and marketing of crude 
oil and NGLs and natural gas and the mining and upgrading of bitumen into SCO. These inherent risks include, but are not limited 
to, the following items:

  The ability to find, produce and replace reserves, whether sourced from exploration, improved recovery or acquisitions, at a 
reasonable cost, including the risk of reserve revisions due to economic and technical factors. Reserve revisions can have a 
positive or negative impact on asset valuations, ARO and depletion rates;

  Reservoir quality and uncertainty of reserve estimates;

  Volatility in the prevailing prices of crude oil and NGLs and natural gas;

  Regulatory risk related to approval for exploration and development activities, which can add to costs or cause delays in projects;

Labour risk associated with securing the manpower necessary to complete capital projects in a timely and cost effective manner;

  Operating hazards and other difficulties inherent in the exploration for and production and sale of crude oil and natural gas;

  Success of exploration and development activities;

  Timing and success of integrating the business and operations of acquired properties and/or companies;

  Credit risk related to non-payment for sales contracts or non-performance by counterparties to contracts, including derivative 

financial instruments and physical sales contracts as part of a hedging program;

Interest rate risk associated with the Company’s ability to secure financing on commercially acceptable terms;

Foreign exchange risk due to fluctuating exchange rates on the Company’s US dollar denominated debt and as predominantly 
all sales are based on US dollar denominated benchmarks;

  Environmental impact risk associated with exploration and development activities, including GHG;

  Geopolitical  risks  associated  with  changing  governments  or  governmental  policies,  social  instability  and  other  political, 

economic or diplomatic developments in the regions where the Company has its operations;

Future legislative and regulatory developments related to environmental regulation;

  Potential actions of governments, regulatory authorities and other stakeholders that may result in costs or restrictions in the 

jurisdictions where the Company has operations;

  Changing royalty regimes;

  Business interruptions because of unexpected events such as fires or explosions whether caused by human error or nature, 
severe storms and other calamitous acts of nature, blowouts, freeze-ups, mechanical or equipment failures of facilities and 
infrastructure and other similar events affecting the Company or other parties whose operations or assets directly or indirectly 
impact the Company and that may or may not be financially recoverable;

  The access to markets for the Company’s products; and

  Other circumstances affecting revenue and expenses.

The Company uses a variety of means to help mitigate and/or minimize these risks. The Company maintains a comprehensive 
property loss and business interruption insurance program to reduce risk to an acceptable level. Operational control is enhanced 
by focusing efforts on large core areas with high working interests and by assuming operatorship of key facilities. Product mix is 
diversified, consisting of the production of natural gas and the production of crude oil of various grades. The Company believes this 
diversification reduces price risk when compared with over-leverage to one commodity. Accounts receivable from the sale of crude 
oil and natural gas are mainly with customers in the crude oil and natural gas industry and are subject to normal industry credit risks. 
The Company manages these risks by reviewing its exposure to individual companies on a regular basis and where appropriate, 
ensures that parental guarantees or letters of credit are in place to minimize the impact in the event of default. Substantially all of 
the Company’s accounts receivables are due within normal trade terms. Derivative financial instruments are utilized to help ensure 
targets are met and to manage commodity price, foreign currency and interest rate exposures. The Company is exposed to possible 
losses in the event of non-performance by counterparties to derivative financial instruments; however, the Company manages 
this credit risk by entering into agreements with substantially all investment grade financial institutions and other entities. The 
arrangements and policies concerning the Company’s financial instruments are under constant review and may change depending 
upon the prevailing market conditions.

The Company’s capital structure mix is also monitored on a continual basis to ensure that it optimizes flexibility, minimizes cost 
and offers the greatest opportunity for growth. This includes the determination of a reasonable level of debt and any interest rate 
exposure risk that may exist.

For additional detail regarding the Company’s risks and uncertainties, refer to the Company’s AIF.

ENVIRONMENT

The Company continues to invest in people, technologies, facilities and infrastructure to recover and process crude oil and natural 
gas resources efficiently and in an environmentally sustainable manner. 

The crude oil and natural gas industry is experiencing incremental increases in costs related to environmental regulation, particularly 
in  North  America  and  the  North  Sea.  Existing  and  expected  legislation  and  regulations  require  the  Company  to  address  and 
mitigate the effect of its activities on the environment. Increasingly stringent laws and regulations may have an adverse effect on 
the Company’s future net earnings and cash flow from operations.

The Company’s associated environmental risk management strategies focus on working with legislators and regulators to ensure 
that any new or revised policies, legislation or regulations properly reflect a balanced approach to sustainable development. Specific 
measures in response to existing or new legislation include a focus on the Company’s energy efficiency, air emissions management, 
released water quality, reduced fresh water use and the minimization of the impact on the landscape. Training and due diligence for 
operators and contractors are key to the effectiveness of the Company’s environmental management programs and the prevention 
of incidents. The Company’s environmental risk management strategies employ an Environmental Management Plan (the “Plan”). 
Details of the Plan, along with performance results, are presented to, and reviewed by, the Board of Directors quarterly. 

The Company’s Plan and operating guidelines focus on minimizing the impact of operations while meeting regulatory requirements, 
regional management frameworks, industry operating standards and guidelines, and internal corporate standards. The Company, 
as part of this Plan, has implemented a proactive program that includes:

  An internal environmental compliance audit and inspection program of the Company’s operating facilities;

  A suspended well inspection program to support future development or eventual abandonment;

  Appropriate reclamation and decommissioning standards for wells and facilities ready for abandonment;

  An effective surface reclamation program;

  A due diligence program related to groundwater monitoring;

  An active program related to preventing and reclaiming spill sites;

  A solution gas conservation program; 

  A program to replace the majority of fresh water for steaming with brackish water;

  Water programs to improve efficiency of use, recycle rates and water storage;

  Environmental planning for all projects to assess impacts and to implement avoidance and mitigation programs;

  Reporting for environmental liabilities;

  A program to optimize efficiencies at the Company’s operated facilities; 

  Continued  evaluation  of  new  technologies  to  reduce  environmental  impacts  and  support  for  Canada’s  Oil  Sands  

Innovation Alliance (“COSIA”);

  CO2 reduction programs including the injection of CO2 into tailings and for use in enhanced oil recovery;

  A program in place related to progressive reclamation and tailings management for the Horizon Oil Sands facility; and

  Participation and support for the Joint Oil Sands Monitoring Program.

The discounted ARO was based on estimates of future costs to abandon and restore wells, production facilities, mine site, upgrading 
facilities  and  tailings,  and  offshore  production  platforms.  Factors  that  affect  costs  include  number  of  wells  drilled,  well  depth, 
facility size and the specific environmental legislation. The estimated future costs are based on engineering estimates of current 
costs in accordance with present legislation, industry operating practice and the expected timing of abandonment. The Company’s 
strategy in the North Sea consists of developing commercial hubs around its core operated properties with the goal of increasing 
production and extending the economic lives of its production facilities, thereby delaying the eventual abandonment dates.

GREENHOUSE GAS AND OTHER AIR EMISSIONS

The  Company,  through  the  Canadian  Association  of  Petroleum  Producers  (“CAPP”),  is  working  with  Canadian  legislators  and 
regulators  as  they  develop  and  implement  new  GHG  emission  laws  and  regulations.  Internally,  the  Company  is  pursuing  an 
integrated emissions reduction strategy, to ensure that it is able to comply with existing and future emissions reduction requirements, 
for both GHGs and air pollutants (such as sulphur dioxide and oxides of nitrogen). The Company continues to develop strategies 
that will enable it to deal with the risks and opportunities associated with new GHG and air emissions policies. In addition, the 
Company is working with relevant parties to ensure that new policies encourage technological innovation, energy efficiency, and 
targeted research and development while not impacting competitiveness.

In Canada, the federal government has indicated its intent to develop regulations that would be in effect in the near term to 
address  industrial  GHG  emissions,  as  part  of  the  national  GHG  reduction  target.  The  federal  government  is  also  developing  a 
comprehensive management system for air pollutants.

In  the  province  of  Alberta,  GHG  reduction  regulations  came  into  effect  July  1,  2007,  affecting  facilities  emitting  more  than  
100 kilotonnes of CO2e annually. Three of the Company’s facilities, the Horizon facility, the Primrose/Wolf Lake in situ heavy crude 
oil facilities and the Hays sour natural gas plant are subject to compliance under the regulations. The Kirby South in situ heavy 
crude oil facility will be subject to compliance under the regulations in 2016. In the province of British Columbia, carbon tax is 
currently being assessed at $30/tonne of CO2e on fuel consumed and gas flared in the province. As part of its involvement with 
the Western Climate Initiative, British Columbia may require certain upstream oil and gas facilities to participate in a regional cap 
and trade system. If such a system is implemented, it is not expected to be in place before 2015. It is estimated that four facilities 
in British Columbia will be included under the cap and trade system, based on a proposed requirement of 25 kilotonne CO2e 
annually. The province of Saskatchewan released draft GHG regulations that regulate facilities emitting more than 50 kilotonnes 
of CO2e annually and will likely require the North Tangleflags in situ heavy oil facility to meet the reduction target for its GHG 
emissions once the governing legislation comes into force. In the UK, GHG regulations have been in effect since 2005. In Phase 1  
(2005 – 2007) of the UK National Allocation Plan, the Company operated below its CO2 allocation. In Phase 2 (2008 – 2012)  
the  Company’s  CO2  allocation  has  been  decreased  below  the  Company’s  estimated  current  operations  emissions.  In  Phase  3  
(2013 – 2020) the Company’s CO2 allocation is expected to be further reduced, although details on Phase 3 have not yet been 
finalized. The Company continues to focus on implementing reduction programs based on efficiency audits to reduce CO2 emissions 
at its major facilities and on trading mechanisms to ensure compliance with requirements now in effect. 

The United States Environmental Protection Agency (“EPA”) is proceeding to regulate GHGs under the Clean Air Act. This EPA 
action  has  been  subject  to  legal  and  political  challenges,  the  outcome  of  which  cannot  be  predicted.  The  ultimate  form  of 
Canadian regulation is anticipated to be strongly influenced by the regulatory decisions made within the United States. Various 
states have enacted or are evaluating low carbon fuel standards, which may  affect access to market  for crude oil with higher  
emissions intensity.

2012 ANNUAL REPORT

 
There  are  a  number  of  unresolved  issues  in  relation  to  Canadian  federal  and  provincial  GHG  regulatory  requirements.  Key 
among  them  is  the  form  of  regulation,  an  appropriate  common  facility  emission  level,  availability  and  duration  of  compliance 
mechanisms, and resolution of federal/provincial harmonization agreements. The Company continues to pursue GHG emission 
reduction initiatives including: solution gas conservation, compressor optimization to improve fuel gas efficiency, CO2 capture and 
sequestration in oil sands tailings, CO2 capture and storage in association with enhanced oil recovery, participation in an industry 
initiative  to  promote  an  integrated  CO2  capture  and  storage  network,  and  participation  in  organizations  that  are  researching 
technologies to reduce GHG emissions (specifically COSIA and Carbon Management Canada (“CMC”)).

The additional requirements of enacted or proposed GHG regulations on the Company’s operations will increase capital expenditures 
and  operating  expenses,  including  those  related  to  Horizon  and  the  Company’s  other  existing  and  certain  planned  oil  sands 
projects. This may have an adverse effect on the Company’s future net earnings and cash flow from operations.

Air pollutant standards and guidelines are being developed federally and provincially and the Company is participating in these 
discussions. Ambient air quality and sector based reductions in air emissions are being reviewed. Through Company and industry 
participation  with  stakeholders,  guidelines  are  being  developed  that  adopt  a  structured  process  to  emission  reductions  that  is 
commensurate with technological development and operational requirements.

CRITICAL ACCOUNTING ESTIMATES AND CHANGE IN ACCOUNTING POLICIES

The preparation of financial statements requires the Company to make estimates, assumptions and judgements in the application 
of IFRS that have a significant impact on the financial results of the Company. Actual results could differ from estimated amounts, 
and those differences may be material. 

Critical accounting estimates are reviewed by the Company’s Audit Committee annually. The Company believes the following are 
the most critical accounting estimates in preparing its consolidated financial statements. 

Depletion, Depreciation and Amortization and Impairment

Exploration and evaluation (“E&E”) asset costs relating to activities to explore and evaluate crude oil and natural gas properties 
are initially capitalized and include costs directly associated with the acquisition of licenses, technical services and studies, seismic 
acquisition, exploration drilling and evaluation, overhead and administration expenses, and the estimate of any asset retirement 
costs. E&E assets are carried forward until technical feasibility and commercial viability of extracting a mineral resource is determined. 
Technical feasibility and commercial viability of extracting a mineral resource is considered to be determined when an assessment 
of proved reserves is made. The judgements associated with the estimation of proved reserves are described below in “Crude Oil 
and Natural Gas Reserves”.

An alternative acceptable accounting method for E&E assets under IFRS 6 “Exploration for and Evaluation of Mineral Resources” 
is to charge exploratory dry holes and geological and geophysical exploration costs incurred after having obtained the legal rights 
to explore an area against net earnings in the period incurred rather than capitalizing to E&E assets.

E&E assets are tested for impairment when facts and circumstances suggest that the carrying amount of E&E assets may exceed 
their recoverable amount, by comparing the relevant costs to the fair value of Cash Generating Units (“CGUs”), aggregated at 
the segment level. Indications of impairment include leases approaching expiry, the existence of low benchmark commodity prices 
for an extended period of time, significant downward revisions in estimated probable reserves volumes, significant increases in 
estimated future exploration or development expenditures, or significant adverse changes in the applicable legislative or regulatory 
frameworks. The determination of the fair value of CGUs requires the use of assumptions and estimates including quantities of 
recoverable reserves, production quantities, future commodity prices and development and production costs. Changes in any of 
these assumptions, such as a downward revision in probable reserves volumes, decrease in commodity prices or increase in costs, 
could impact the fair value.

Property, plant and equipment is measured at cost less accumulated depletion and depreciation and impairment provisions. Crude 
oil and natural gas properties in the Exploration and Production segments are depleted using the unit-of-production method over 
proved reserves, except for major components, which are depreciated using a straight-line method over their estimated useful 
lives. The unit-of-production rate takes into account expenditures incurred to date, together with future estimated development 
expenditures required to develop proved reserves. Estimates of proved reserves have a significant impact on net earnings, as they 
are a key input to the calculation of depletion expense.

CANADIAN NATURAL

2012 ANNUAL REPORT

The Company assesses property, plant and equipment for impairment whenever events or changes in circumstances indicate that 
the carrying value of an asset or group of assets may not be recoverable. Indications of impairment include the existence of low 
commodity prices for an extended period, significant downward revisions of estimated reserves volumes, significant increases in 
estimated future development expenditures, or significant adverse changes in the applicable legislative or regulatory frameworks. 
If any such indication of impairment exists, the Company performs an impairment test related to the specific assets. Individual 
assets are grouped for impairment assessment purposes into CGU’s, which are the lowest level at which there are identifiable cash 
inflows that are largely independent of the cash inflows of other groups of assets. The determination of fair value of CGUs requires 
the use of assumptions and estimates including quantities of recoverable reserves, production quantities, future commodity prices, 
discount rates and income taxes as well as development and production costs. Changes in any of these assumptions, such as a 
downward revision in reserves, decrease in commodity prices or increase in costs, could impact the fair value.

Crude Oil and Natural Gas Reserves

Reserve estimates are based on engineering data, estimated future prices, expected future rates of production and the timing of 
future capital expenditures, all of which are subject to many uncertainties, interpretations, and judgements. The Company expects 
that, over time, its reserve estimates will be revised upward or downward based on updated information such as the results of 
future drilling, testing and production levels, and may be affected by changes in commodity prices. Reserve estimates can have 
a significant impact on net earnings, as they are a key component in the calculation of depletion, depreciation and amortization 
and for determining potential asset impairment. For example, a revision to the proved reserve estimates would result in a higher or 
lower depletion, depreciation and amortization charge to net earnings. Downward revisions to reserve estimates may also result in 
an impairment of property, plant and equipment and E&E carrying amounts.

Asset Retirement Obligations

The  Company  is  required  to  recognize  a  liability  for  ARO  associated  with  its  property,  plant  and  equipment.  An  ARO  liability 
associated with the retirement of a tangible long-lived asset is recognized to the extent of a legal obligation resulting from an 
existing or enacted law, statute, ordinance or written or oral contract, or by legal construction of a contract under the doctrine of 
promissory estoppel. The ARO is based on estimated costs, taking into account the anticipated method and extent of restoration 
consistent with legal requirements, technological advances and the possible use of the site. Since these estimates are specific to the 
sites involved, there are many individual assumptions underlying the Company’s total ARO amount. These individual assumptions 
can be subject to change. 

The  estimated  present  values  of  ARO  related  to  long-term  assets  are  recognized  as  a  liability  in  the  period  in  which  they  are 
incurred. The provision for the ARO is estimated by discounting the expected future cash flows to settle the ARO at the Company’s 
average credit-adjusted risk-free interest rate, which is currently 4.3%. Subsequent to initial measurement, the ARO is adjusted to 
reflect the passage of time, changes in credit adjusted interest rates, and changes in the estimated future cash flows underlying the 
obligation. The increase in the provision due to the passage of time is recognized as asset retirement obligation accretion expense 
whereas changes in discount rates or the estimated future cash flows are capitalized to or derecognized from property, plant and 
equipment. Changes in estimates would impact accretion and depletion expense in net earnings. In addition, differences between 
actual and estimated costs to settle the ARO, timing of cash flows to settle the obligation and future inflation rates may result in 
gains or losses on the final settlement of the ARO. 

Income Taxes

The Company follows the liability method of accounting for income taxes. Under this method, deferred income tax assets and 
liabilities are recognized based on the estimated tax effects of temporary differences in the carrying value of assets and liabilities 
in the consolidated financial statements and their respective tax bases, using income tax rates substantively enacted as at the date 
of the balance sheet. Accounting for income taxes requires the Company to interpret frequently changing laws and regulations, 
including  changing  income  tax  rates,  and  make  certain  judgements  with  respect  to  the  application  of  tax  law,  estimating  the 
timing of temporary difference reversals, and estimating the realizability of tax assets. There are many transactions and calculations 
for which the ultimate tax determination is uncertain. The Company recognizes liabilities for potential tax audit issues based on 
assessments of whether additional taxes will likely be due.

Risk Management Activities

The  Company  uses  various  derivative  financial  instruments  to  manage  its  commodity  price,  foreign  currency  and  interest  rate 
exposures. These financial instruments are entered into solely for hedging purposes and are not used for speculative purposes.

The  estimated  fair  value  of  derivative  financial  instruments  has  been  determined  based  on  appropriate  internal  valuation 
methodologies  and/or  third  party  indications.  Fair  values  determined  using  valuation  models  require  the  use  of  assumptions 
concerning  the  amount  and  timing  of  future  cash  flows  and  discount  rates.  In  determining  these  assumptions,  the  Company 
uses directly and indirectly observable inputs in measuring the value of financial instruments that are not traded in active markets, 
including quoted commodity prices and volatility, interest rate yield curves, and foreign exchange rates. The resulting fair value 
estimates may not necessarily be indicative of the amounts that could be realized or settled in a current market transaction and 
these differences may be material.

Purchase Price Allocations

Purchase prices related to business combinations and asset acquisitions are allocated to the underlying acquired assets and liabilities 
based  on  their  estimated  fair  value  at  the  time  of  acquisition.  The  determination  of  fair  value  requires  the  Company  to  make 
estimates, assumptions and judgements regarding future events. The allocation process is inherently subjective and impacts the 
amounts assigned to individually identifiable assets and liabilities, including the fair value of crude oil and natural gas properties. 
As a result, the purchase price allocation impacts the Company’s reported assets and liabilities and future net earnings due to the 
impact on future depletion, depreciation and amortization expense and impairment tests.

The Company has made various assumptions in determining the fair values of the acquired assets and liabilities. The most significant 
assumptions and judgements relate to the estimation of the fair value of the crude oil and natural gas properties. To determine the 
fair value of these properties, the Company estimates (a) crude oil and natural gas reserves, and (b) future prices of crude oil and 
natural gas. Reserve estimates are based on the work performed by the Company’s internal engineers and outside consultants. 
The judgements associated with these estimated reserves are described above in “Crude Oil and Natural Gas Reserves”. Estimates 
of future prices are based on prices derived from price forecasts among industry analysts and internal assessments. The Company 
applies estimated future prices to the estimated reserves quantities acquired, and estimates future operating and development 
costs, to arrive at estimated future net revenues for the properties acquired.

Share-Based Compensation

The Company has made various assumptions in estimating the fair values of stock options granted including expected volatility, 
expected exercise behavior and future forfeiture rates. At each period end, stock options outstanding are remeasured for subsequent 
changes in the fair value of the liability. 

CONTROL ENVIRONMENT

The Company’s management, including the President and the Chief Financial Officer and Senior Vice-President, Finance, evaluated 
the  effectiveness  of  disclosure  controls  and  procedures  as  at  December  31,  2012,  and  concluded  that  disclosure  controls  and 
procedures are effective to ensure that information required to be disclosed by the Company in its annual filings and other reports 
filed with securities regulatory authorities in Canada and the United States is recorded, processed, summarized and reported within 
the time periods specified and such information is accumulated and communicated to the Company’s management to allow timely 
decisions regarding required disclosures.

The Company’s management also performed an assessment of internal control over financial reporting as at December 31, 2012, 
and concluded that internal control over financial reporting is effective. Further, there were no changes in the Company’s internal 
control over financial reporting during 2012 that have materially affected, or are reasonably likely to materially affect, internal 
control over financial reporting. 

While  the  Company’s  management  believes  that  the  Company’s  disclosure  controls  and  procedures  and  internal  control  over 
financial  reporting  provide  a  reasonable  level  of  assurance  they  are  effective,  they  recognize  that  all  control  systems  have 
inherent limitations. Because of its inherent limitations, the Company’s control systems may not prevent or detect misstatements.  
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

INTERNATIONAL FINANCIAL REPORTING STANDARDS

In 2010, the CICA Handbook was revised to incorporate IFRS and require publicly accountable enterprises to apply IFRS effective for 
years beginning on or after January 1, 2011. The 2011 fiscal year was the first year in which the Company prepared its consolidated 
financial statements and the related notes in accordance with IFRS as issued by the IASB.

The accounting policies adopted by the Company under IFRS are set out in note 1 to the Company’s consolidated financial statements. 

Unless otherwise stated, comparative figures for 2010 have been restated from Canadian GAAP to comply with IFRS. 

ACCOUNTING STANDARDS ISSUED BUT NOT YET APPLIED

In May 2011, the IASB issued the following new accounting standards, which are required to be adopted effective January 1, 2013:

IFRS  10  “Consolidated  Financial  Statements”  replaces  IAS  27  “Consolidated  and  Separate  Financial  Statements”  (IAS  27 
still  contains  guidance  for  Separate  Financial  Statements)  and  SIC  12  “Consolidation  –  Special  Purpose  Entities”.  IFRS  10 
establishes the principles for the presentation and preparation of consolidated financial statements. The standard defines the 
principle of control and establishes control as the basis for consolidation, as well as providing guidance on how to apply the 
control principle to determine whether an investor controls an investee. 

IFRS  11  “Joint  Arrangements”  replaces  IAS  31  “Interests  in  Joint  Ventures”  and  SIC  13  “Jointly  Controlled  Entities  –  
Non-Monetary Contributions by Venturers”. The new standard defines two types of joint arrangements, joint operations and 
joint ventures. In a joint operation, the parties with joint control have rights to the assets and obligations for the liabilities of 
the joint arrangement and are required to recognize their proportionate interest in the assets, liabilities, revenues and expenses 
of the joint arrangement. In a joint venture, the parties have an interest in the net assets of the arrangement and are required 
to apply the equity method of accounting. 

IFRS 12 “Disclosure of Interests in Other Entities”. The standard includes disclosure requirements for investments in subsidiaries, 
joint arrangements, associates and unconsolidated structured entities. This standard does not impact the Company’s accounting 
for investments in other entities, but may impact the related disclosures.

  Adoption of the above standards is not expected to result in a significant accounting change to the Company’s consolidated 

financial statements, but may impact the related disclosures.

In May 2011, the IASB also issued IFRS 13 “Fair Value Measurement”, effective January 1, 2013, which provides guidance on how 
fair value should be applied where its use is already required or permitted by other standards within IFRS. The standard includes 
a definition of fair value and a single source of fair value measurement and disclosure requirements for use across all IFRSs that 
require or permit the use of fair value. The Company will be required to include its own credit risk in measuring the carrying amount 
of a risk management liability. In addition, the new standard may impact certain fair value disclosures.

The Company is required to adopt IFRS 9, “Financial Instruments”, effective January 1, 2015, with earlier adoption permitted. IFRS 9  
replaces existing requirements included in IAS 39, “Financial Instruments - Recognition and Measurement”. The new standard 
replaces the multiple classification and measurement models for financial assets and liabilities with a new model that has only two 
categories: amortized cost and fair value through profit and loss. Under IFRS 9, fair value changes due to credit risk for liabilities 
designated at fair value through profit and loss would generally be recorded in other comprehensive income. The Company is 
currently assessing the impact of this new standard on its consolidated financial statements.

In  June  2011,  the  IASB  issued  amendments  to  IAS  1  “Presentation  of  Financial  Statements”  that  require  items  of  other 
comprehensive income that may be reclassified to net earnings to be grouped together. The amendments also require that items 
in other comprehensive income and net earnings be presented as either a single statement or two consecutive statements. The 
standard is effective for fiscal years beginning on or after July 1, 2012. Adoption of this amended standard is not expected to result 
in a significant change in the presentation of the Company’s consolidated financial statements.

In October 2011, the IASB issued IFRS Interpretation Committee (“IFRIC”) 20 “Stripping Costs in the Production Phase of a Surface 
Mine”. The IFRIC requires overburden removal costs during the production phase to be capitalized and depreciated if the Company 
can demonstrate that probable future economic benefits will be realized, the costs can be reliably measured, and the Company can 
identify the component of the ore body for which access has been improved. The IFRIC is effective for fiscal periods beginning on 
or after January 1, 2013. Adoption of this standard is not expected to result in a significant change to the Company’s consolidated 
financial statements.

OUTLOOK 

The Company continues to implement its strategy of maintaining a large portfolio of varied projects, which the Company believes 
will enable it, over an extended period of time, to provide consistent growth in production and create shareholder value. Annual 
budgets are developed, scrutinized throughout the year and revised if necessary in the context of targeted financial ratios, project 
returns, product pricing expectations, and balance in project risk and time horizons. The Company maintains a high ownership 
level and operatorship level in all of its properties and can therefore control the nature, timing and extent of capital expenditures 
in each of its project areas. The Company targets production levels in 2013 to average between 482,000 bbl/d and 513,000 bbl/d 
of crude oil and NGLs and between 1,085 MMcf/d and 1,145 MMcf/d of natural gas.

MANAGEMENT’S REPORT

The accompanying consolidated financial statements and all other information contained elsewhere in this Annual Report are the 
responsibility  of  management.  The  consolidated  financial  statements  have  been  prepared  by  management  in  accordance  with 
the  accounting  policies  described  in  the  accompanying  notes.  Where  necessary,  management  has  made  informed  judgements 
and estimates in accounting for transactions that were not complete at the balance sheet date. In the opinion of management, 
the financial statements have been prepared in accordance with International Financial Reporting Standards appropriate in the 
circumstances. The financial information presented elsewhere in the Annual Report has been reviewed to ensure consistency with 
that in the consolidated financial statements.

Management maintains appropriate systems of internal control. Policies and procedures are designed to give reasonable assurance 
that transactions are appropriately authorized and recorded, assets are safeguarded from loss or unauthorized use and financial 
records are properly maintained to provide reliable information for preparation of financial statements.

PricewaterhouseCoopers LLP, an independent firm of Chartered Accountants, has been engaged, as approved by a vote of the 
shareholders at the Company’s most recent Annual General Meeting, to audit and provide their independent audit opinions on 
the following:

the Company’s consolidated financial statements as at and for the year ended December 31, 2012; and

the effectiveness of the Company’s internal control over financial reporting as at December 31, 2012.

Their report is presented with the consolidated financial statements.

The Board of Directors (the “Board”) is responsible for ensuring that management fulfills its responsibilities for financial reporting 
and internal controls. The Board exercises this responsibility through the Audit Committee of the Board, which is comprised entirely 
of  independent  directors.  The  Audit  Committee  meets  with  management  and  the  independent  auditors  to  satisfy  itself  that 
management responsibilities are properly discharged and to review the consolidated financial statements before they are presented 
to the Board for approval. The consolidated financial statements have been approved by the Board on the recommendation of the 
Audit Committee.

MANAGEMENT’S ASSESSMENT  
OF INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company as 
defined in Rules 13a–15(f) and 15d–15(f) under the United States Securities Exchange Act of 1934, as amended.

Management, including the Company’s President and the Company’s Chief Financial Officer and Senior Vice-President, Finance, 
performed an assessment of the Company’s internal control over financial reporting based on the criteria established in Internal 
Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

Based on the assessment, management has concluded that the Company’s internal control over financial reporting is effective as 
at December 31, 2012. Management recognizes that all internal control systems have inherent limitations. Because of its inherent 
limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation 
of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, 
or that the degree of compliance with the policies or procedures may deteriorate.

PricewaterhouseCoopers LLP, an independent firm of Chartered Accountants, has provided an opinion on the Company’s internal 
control over financial reporting as at December 31, 2012, as stated in their Auditor’s Report.

2012 ANNUAL REPORT

 
INDEPENDENT AUDITOR’S REPORT

To the Shareholders of Canadian Natural Resources Limited

We have completed integrated audits of Canadian Natural Resources Limited’s 2012 and 2011 consolidated financial statements 
and its internal control over financial reporting as at December 31, 2012 and an audit of its 2010 consolidated financial statements. 
Our opinions, based on our audits are presented below.

Report on the consolidated financial statements 

We have audited the accompanying consolidated financial statements of Canadian Natural Resources Limited, which comprise 
the consolidated balance sheets as at December 31, 2012 and December 31, 2011 and the consolidated statements of earnings, 
comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2012, and 
the related notes, which comprise a summary of significant accounting policies and other explanatory information. 

Management’s responsibility for the consolidated financial statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with 
International Financial Reporting Standards as issued by the International Accounting Standards Board and for such internal control 
as management determines is necessary to enable the preparation of consolidated financial statements that are free from material 
misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our 
audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting 
Oversight  Board  (United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance 
about whether the consolidated financial statements are free from material misstatement. Canadian generally accepted auditing 
standards also require that we comply with ethical requirements.

An  audit  involves  performing  procedures  to  obtain  audit  evidence,  on  a  test  basis,  about  the  amounts  and  disclosures  in  the 
consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks 
of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, 
the auditor considers internal control relevant to the company’s preparation and fair presentation of the consolidated financial 
statements in order to design audit procedures that are appropriate in the circumstances. An audit also includes evaluating the 
appropriateness of accounting principles and policies used and the reasonableness of accounting estimates made by management, 
as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit 
opinion on the consolidated financial statements.

Opinion

In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  Canadian 
Natural Resources Limited as at December 31, 2012 and December 31, 2011 and its financial performance and its cash flows for 
each of the three years in the period ended December 31, 2012 in accordance with International Financial Reporting Standards as 
issued by the International Accounting Standards Board.

Report on internal control over financial reporting 

We have also audited Canadian Natural Resources Limited’s internal control over financial reporting as at December 31, 2012, 
based on criteria established in Internal Control - Integrated Framework, issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO).

Management’s responsibility for internal control over financial reporting

Management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the 
effectiveness of internal control over financial reporting included in the accompanying Management’s Report.

Auditor’s responsibility

Our responsibility is to express an opinion on Canadian Natural Resources Limited’s internal control over financial reporting based on 
our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company 
Accounting  Oversight  Board  (United  States).  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material respects.

An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, 
assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control, 
based on the assessed risk, and performing such other procedures as we consider necessary in the circumstances.

We believe that our audit provides a reasonable basis for our audit opinion on Canadian Natural Resources Limited’s internal control 
over financial reporting.

Definition of internal control over financial reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted 
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that: (i) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that 
could have a material effect on the financial statements.

Inherent limitations

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Opinion

In our opinion, Canadian Natural Resources Limited maintained, in all material respects, effective internal control over financial 
reporting as at December 31, 2012, based on criteria established in Internal Control - Integrated Framework issued by COSO.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in millions of Canadian dollars, unless otherwise stated)

1.   ACCOUNTING POLICIES

Canadian Natural Resources Limited (the “Company”) is a senior independent crude oil and natural gas exploration, development 
and production company. The Company’s exploration and production operations are focused in North America, largely in Western 
Canada; the United Kingdom (“UK”) portion of the North Sea; and Côte d’Ivoire, Gabon, and South Africa in Offshore Africa. 

The  Horizon  Oil  Sands  Mining  and  Upgrading  segment  (“Horizon”)  produces  synthetic  crude  oil  through  bitumen  mining  and 
upgrading operations.

Within Western Canada, the Company maintains certain midstream activities that include pipeline operations, an electricity co-
generation system and an investment in the North West Redwater Partnership (“Redwater”).

The  Company  was  incorporated  in  Alberta,  Canada.  The  address  of  its  registered  office  is  2500,  855-2  Street  S.W.,  Calgary, 
Alberta, Canada. 

The  Company’s  consolidated  financial  statements  and  the  related  notes  have  been  prepared  in  accordance  with  International 
Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The accounting policies 
adopted  by  the  Company  under  IFRS  are  set  out  below.  The  Company  has  consistently  applied  the  same  accounting  policies 
throughout all periods presented. 

(A)  Principles of Consolidation

The consolidated financial statements have been prepared under the historical cost convention, unless otherwise required. 

The  consolidated  financial  statements  include  the  accounts  of  the  Company  and  all  of  its  subsidiary  companies  and  wholly  
owned partnerships. 

Certain of the Company’s activities are conducted through joint ventures. Where the Company has a direct ownership interest 
in jointly controlled assets, the assets, liabilities, revenue and expenses related to the jointly controlled assets are included in the 
consolidated financial statements in proportion to the Company’s interest. Where the Company has an interest in jointly controlled 
entities, it uses the equity method of accounting. Under the equity method, the Company’s initial and subsequent investments 
are recognized at cost and subsequently adjusted for the Company’s share of the jointly controlled entity’s income or loss, less 
dividends received.

(B)  Segmented Information

Operating segments have been determined based on the nature of the Company’s activities and the geographic locations in which 
the Company operates, and are consistent with the level of information regularly provided to and reviewed by the Company’s chief 
operating decision makers.

(C)  Cash and Cash Equivalents

Cash comprises cash on hand and demand deposits. Other investments (term deposits and certificates of deposit) with an original 
term to maturity at purchase of three months or less are reported as cash equivalents in the consolidated balance sheets.

(D)  Inventory

Inventory is primarily comprised of product inventory and  materials and supplies. Product inventory includes crude oil  held  for 
sale,  pipeline  linefill  and  crude  oil  stored  in  floating  production,  storage  and  offloading  vessels.  Inventories  are  carried  at  the 
lower of cost and net realizable value. Cost consists of purchase costs, direct production costs, directly attributable overhead and 
depletion, depreciation and amortization and is determined on a first-in, first-out basis. Net realizable value for product inventory 
is determined by reference to forward prices, and for materials and supplies is based on current market prices as at the date of the 
consolidated balance sheets.

(E)   Exploration and Evaluation Assets 

Exploration and evaluation (“E&E”) assets consist of the Company’s crude oil and natural gas exploration projects that are pending 
the determination of proved reserves. 

E&E costs are initially capitalized and include costs directly associated with the acquisition of licenses, technical services and studies, 
seismic  acquisition,  exploration  drilling  and  evaluation,  overhead  and  administration  expenses,  and  the  estimate  of  any  asset 
retirement costs. E&E costs do not include general prospecting or evaluation costs incurred prior to having obtained the legal rights 
to explore an area. These costs are recognized in net earnings.

Once  the  technical  feasibility  and  commercial  viability  of  E&E  assets  are  determined  and  a  development  decision  is  made  by 
management,  the  E&E  assets  are  tested  for  impairment  upon  reclassification  to  property,  plant  and  equipment.  The  technical 
feasibility and commercial viability of extracting a mineral resource is considered to be determined when an assessment of proved 
reserves is made.

E&E  assets  are  also  tested  for  impairment  when  facts  and  circumstances  suggest  that  the  carrying  amount  of  E&E  assets  may 
exceed their recoverable amount, by comparing the relevant costs to the fair value of Cash Generating Units (“CGUs”), aggregated 
at the segment level. Indications of impairment include leases approaching expiry, the existence of low benchmark commodity 
prices for an extended period of time, significant downward revisions in estimated probable reserves volumes, significant increases 
in  estimated  future  exploration  or  development  expenditures,  or  significant  adverse  changes  in  the  applicable  legislative  or  
regulatory frameworks.

(F)   Property, Plant and Equipment

Property, plant and equipment is measured at cost less accumulated depletion and depreciation and impairment provisions. Assets 
under construction are not depleted or depreciated until available for their intended use. The capitalized value of a finance lease is 
included in property, plant and equipment. 

Exploration and Production 

When significant components of an item of property, plant and equipment, including crude oil and natural gas interests, have 
different useful lives, they are accounted for separately.

The cost of an asset comprises its acquisition, construction and development costs, costs directly attributable to bringing the asset 
into operation, the estimate of any asset retirement costs, and applicable borrowing costs. Property acquisition costs are comprised 
of the aggregate amount paid and the fair value of any other consideration given to acquire the asset. 

Crude  oil  and  natural  gas  properties  are  depleted  using  the  unit-of-production  method  over  proved  reserves,  except  for  major 
components, which are depreciated using a straight-line method over their estimated useful lives. The unit-of-production rate takes 
into account expenditures incurred to date, together with future development expenditures required to develop proved reserves.

Oil Sands Mining and Upgrading 

Capitalized costs for the Oil Sands Mining and Upgrading segment are reported separately from the Company’s North America 
Exploration  and  Production  segment.  Capitalized  costs  include  property  acquisition,  construction  and  development  costs,  
the estimate of any asset retirement costs, and applicable borrowing costs. 

Mine-related costs are amortized on the unit-of-production method based on Horizon proved reserves. Costs of the upgrader and 
related infrastructure located on the Horizon site are amortized on the unit-of-production method based on productive capacity 
of the upgrader and related infrastructure. Other equipment is depreciated on a straight-line basis over its estimated useful life 
ranging from 2 to 15 years.

Midstream and Head Office

The Company capitalizes all costs that expand the capacity or extend the useful life of the assets. Midstream assets are depreciated 
on a straight-line basis over their estimated useful lives ranging from 5 to 30 years. Head office assets are amortized on a declining 
balance basis. 

Useful lives

The expected useful lives of property, plant and equipment are reviewed on an annual basis, with changes in useful lives accounted 
for prospectively.

CANADIAN NATURAL

2012 ANNUAL REPORT

Derecognition

An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected to 
arise  from  the  continued  use  of  the  asset.  Any  gain  or  loss  arising  on  derecognition  of  the  asset  (calculated  as  the  difference 
between the net disposal proceeds and the carrying amount of the item) is recognized in net earnings.

Major maintenance expenditures

Inspection costs associated with major maintenance turnarounds are capitalized and amortized over the period to the next major 
maintenance turnaround. All other maintenance costs are expensed as incurred.

Impairment

The Company assesses property, plant and equipment for impairment whenever events or changes in circumstances indicate that 
the carrying amount of an asset or group of assets may not be recoverable. Indications of impairment include the existence of 
low benchmark commodity prices for an extended period of time, significant downward revisions of estimated reserves volumes, 
significant  increases  in  estimated  future  development  expenditures,  or  significant  adverse  changes  in  the  applicable  legislative 
or regulatory frameworks. If any such indication of impairment exists, the Company performs an impairment test related to the 
assets. Individual assets are grouped for impairment assessment purposes into CGU’s, which are the lowest level at which there are 
identifiable cash inflows that are largely independent of the cash inflows of other groups of assets. A CGU’s recoverable amount 
is the higher of its fair value less costs to sell and its value in use. Where the carrying amount of a CGU exceeds its recoverable 
amount, the CGU is considered impaired and is written down to its recoverable amount. 

In subsequent periods, an assessment is made at each reporting date to determine whether there is any indication that previously 
recognized  impairment  losses  may  no  longer  exist  or  may  have  decreased.  If  such  indication  exists,  the  recoverable  amount  is  
re-estimated and the net carrying amount of the asset is increased to its revised recoverable amount. The recoverable amount 
cannot exceed the carrying amount that would have been determined, net of depletion, had no impairment loss been recognized 
for the asset in prior periods. Such reversal is recognized in net earnings. After a reversal, the depletion charge is adjusted in future 
periods to allocate the asset’s revised carrying amount over its remaining useful life.

(G)  Business Combinations 

Business  combinations  are  accounted  for  using  the  acquisition  method.  Assets  acquired  and  liabilities  assumed  in  a  business 
combination are recognized at their fair value at the date of the acquisition. 

(H)  Overburden Removal Costs

Overburden removal costs incurred during the initial development of a mine are capitalized to property, plant and equipment. 
Overburden removal costs incurred during the production of a mine are included in the cost of inventory, unless the overburden 
removal  activity  has  resulted  in  a  probable  inflow  of  future  economic  benefits  to  the  Company,  in  which  case  the  costs  are 
capitalized  to  property,  plant  and  equipment.  Capitalized  overburden  removal  costs  are  amortized  over  the  life  of  the  mining 
reserves that directly benefit from the overburden removal activity.

(I)   Capitalized Borrowing Costs 

Borrowing costs attributable to the acquisition, construction or production of qualifying assets are capitalized to the cost of those 
assets  until  such  time  as  the  assets  are  substantially  available  for  their  intended  use.  Qualifying  assets  are  comprised  of  those 
significant assets that require a period greater than one year to be available for their intended use. All other borrowing costs are 
recognized in net earnings.

(J)   Leases

Finance leases, which transfer substantially all of the risks and rewards incidental to ownership of the leased item to the Company, 
are capitalized at the commencement of the lease term at the fair value of the leased property or, if lower, at the present value of 
the minimum lease payments. Capitalized leased assets are depreciated over the shorter of the estimated useful life of the asset or 
the lease term. Operating lease payments are recognized in net earnings over the lease term.

(K)  Asset Retirement Obligations

The Company provides for asset retirement obligations on all of its property, plant and equipment based on current legislation and 
industry operating practices. Provisions for asset retirement obligations related to property, plant and equipment are recognized 
as a liability in the period in which they are incurred. Provisions are measured at the present value of management’s best estimate 
of expenditures required to settle the obligation as at the date of the balance sheet. Subsequent to the initial measurement, the 
obligation is adjusted to reflect the passage of time, changes in credit adjusted interest rates, and changes in the estimated future 
cash flows underlying the obligation. The increase in the provision due to the passage of time is recognized as asset retirement 
obligation  accretion  expense  whereas  changes  due  to  discount  rates  or  the  estimated  future  cash  flows  are  capitalized  to  or 
derecognized from property, plant, and equipment. Actual costs incurred upon settlement of the asset retirement obligation are 
charged against the provision.

(L)   Foreign Currency Translation

(i)   Functional and presentation currency

Items  included  in  the  financial  statements  of  the  Company’s  subsidiary  companies  and  partnerships  are  measured  using  the 
currency  of  the  primary  economic  environment  in  which  the  subsidiary  operates  (the  “functional  currency”).  The  consolidated 
financial statements are presented in Canadian dollars, which is the Company’s functional currency.

The assets and liabilities of subsidiaries that have a functional currency different from that of the Company are translated into 
Canadian dollars at the closing rate at the date of the balance sheet, and revenue and expenses are translated at the average rate 
for the period. Cumulative foreign currency translation adjustments are recognized in other comprehensive income.

When the Company disposes of its entire interest in a foreign operation, or loses control, joint control, or significant influence 
over a foreign operation, the foreign currency gains or losses accumulated in other comprehensive income related to the foreign 
operation are recognized in net earnings. 

(ii)   Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the 
transactions.  Foreign  exchange  gains  and  losses  resulting  from  the  settlement  of  foreign  currency  transactions  and  from  the 
translation  at  balance  sheet  date  exchange  rates  of  monetary  assets  and  liabilities  denominated  in  currencies  other  than  the 
functional currency of the Company or its subsidiaries are recognized in net earnings.

(M)  Revenue Recognition and Costs of Goods Sold

Revenue  from  the  sale  of  crude  oil  and  natural  gas  is  recognized  when  title  passes  to  the  customer,  delivery  has  taken  place 
and collection is reasonably assured. The Company assesses customer creditworthiness, both before entering into contracts and 
throughout the revenue recognition process.

Revenue represents the Company’s share net of royalty payments to governments and other mineral interest owners. Related costs 
of goods sold are comprised of production, transportation and blending, and depletion, depreciation and amortization expenses. 
These amounts have been separately presented in the consolidated statements of earnings.

(N)  Production Sharing Contracts

Production generated from Offshore Africa is shared under the terms of various Production Sharing Contracts (“PSCs”). Product 
sales are divided into cost recovery oil and profit oil. Cost recovery oil allows the Company to recover its capital and production 
costs and the costs carried by the Company on behalf of the respective Government State Oil Companies (the “Governments”). 
Profit oil is allocated to the joint venture partners in accordance with their respective equity interests, after a portion has been 
allocated to the Governments. The Governments’ share of profit oil attributable to the Company’s equity interest is allocated to 
royalty expense and current income tax expense in accordance with the terms of the respective PSCs. 

(O)  Income Tax

The Company follows the liability method of accounting for income taxes. Under this method, deferred income tax assets and 
liabilities are recognized based on the estimated tax effects of temporary differences in the carrying amount of assets and liabilities 
in the consolidated financial statements and their respective tax bases.

66

CANADIAN NATURAL

2012 ANNUAL REPORT

Deferred  income  tax  assets  and  liabilities  are  calculated  using  the  substantively  enacted  income  tax  rates  that  are  expected  to 
apply when the asset or liability is recovered. Deferred income tax assets or liabilities are not recognized when they arise on the 
initial recognition of an asset or liability in a transaction (other than in a business combination) that, at the time of the transaction, 
affects neither accounting nor taxable profit. Deferred income tax assets or liabilities are also not recognized on possible future 
distributions of retained earnings of subsidiaries where the timing of the distribution can be controlled by the Company and it 
is probable that a distribution will not be made in the foreseeable future, or when distributions can be made without incurring 
income taxes. 

Deferred income tax assets for deductible temporary differences and tax loss carryforwards are recognized to the extent that it 
is probable that future taxable profits will be available against which the temporary differences or tax loss carryforwards can be 
utilized. The carrying amount of deferred income tax assets is reviewed at each reporting date, and is reduced if it is no longer 
probable that sufficient future taxable profits will be available against which the temporary differences or tax loss carryforwards 
can be utilized.

Current income tax is calculated based on net earnings for the period, adjusted for items that are non-taxable or taxed in different 
periods, using income tax rates that are substantively enacted at each reporting date. 

Income taxes are recognized in net earnings or other comprehensive income, consistent with the items to which they relate.

(P)  Share-Based Compensation

The Company’s Stock Option Plan (the “Option Plan”) provides current employees with the right to elect to receive common shares 
or a cash payment in exchange for stock options surrendered. The liability for awards granted to employees is initially measured 
based on the grant date fair value of the awards and the number of awards expected to vest. The awards are re-measured each 
reporting period for subsequent changes in the fair value of the liability. Fair value is determined using the Black-Scholes valuation 
model. Expected volatility is estimated based on historic results. When stock options are surrendered for cash, the cash settlement 
paid reduces the outstanding liability. When stock options are exercised for common shares under the Option Plan, consideration 
paid by the employee and any previously recognized liability associated with the stock options are recorded as share capital.

(Q)  Financial Instruments

The  Company  classifies  its  financial  instruments  into  one  of  the  following  categories:  fair  value  through  profit  or  loss;  
held-to-maturity investments; loans and receivables; and financial liabilities measured at amortized cost. All financial instruments 
are measured at fair value on initial recognition. Measurement in subsequent periods is dependent on the classification of the 
respective financial instrument. 

Fair value through profit or loss financial instruments are subsequently measured at fair value with changes in fair value recognized 
in net earnings. All other categories of financial instruments are measured at amortized cost using the effective interest method. 

Cash,  cash  equivalents,  and  accounts  receivable  are  classified  as  loans  and  receivables.  Accounts  payable,  accrued  liabilities, 
certain  other  long-term  liabilities,  and  long-term  debt  are  classified  as  other  financial  liabilities  measured  at  amortized  cost.  
Risk management assets and liabilities are classified as fair value through profit or loss. 

Financial assets and liabilities are also categorized using a three-level hierarchy that reflects the significance of the inputs used in 
making fair value measurements for these assets and liabilities. The fair values of financial assets and liabilities included in Level 1 
are determined by reference to quoted prices in active markets for identical assets and liabilities. Fair values of financial assets and 
liabilities in Level 2 are based on inputs other than Level 1 quoted prices that are observable for the asset or liability either directly 
(as prices) or indirectly (derived from prices). The fair values of Level 3 financial assets and liabilities are not based on observable 
market data. The disclosure of the fair value hierarchy excludes financial assets and liabilities where book value approximates fair 
value due to the liquid nature of the asset or liability.

Transaction costs in respect of financial instruments at fair value through profit or loss are recognized in net earnings. Transaction 
costs in respect of other financial instruments are included in the initial measurement of the financial instrument.

Impairment of financial assets 

At  each  reporting  date,  the  Company  assesses  whether  there  is  objective  evidence  that  a  financial  asset  is  impaired.  If  such 
evidence exists, an impairment loss is recognized.

Impairment losses on financial assets carried at amortized cost including loans and receivables are calculated as the difference 
between the amortized cost of the loan or receivable and the present value of the estimated future cash flows, discounted using 
the  instrument’s  original  effective  interest  rate.  Impairment  losses  on  financial  assets  carried  at  amortized  cost  are  reversed  in 
subsequent periods if the amount of the loss decreases and the decrease can be related objectively to an event occurring after the 
impairment was recognized.

(R)  Risk Management Activities

The Company uses derivative financial instruments to manage its commodity price, foreign currency and interest rate exposures. 
These financial instruments are entered into solely for hedging purposes and are not used for speculative purposes. All derivative 
financial  instruments  are  recognized  in  the  consolidated  balance  sheets  at  their  estimated  fair  value.  The  estimated  fair  value 
of  derivative  financial  instruments  has  been  determined  based  on  appropriate  internal  valuation  methodologies  and/or  third 
party  indications.  Fair  values  determined  using  valuation  models  require  the  use  of  assumptions  concerning  the  amount  and 
timing  of  future  cash  flows  and  discount  rates.  In  determining  these  assumptions,  the  Company  primarily  relied  on  external,  
readily-observable market inputs including quoted commodity prices and volatility, interest rate yield curves, and foreign exchange 
rates. The Company’s own credit risk is not included in the carrying amount of a risk management liability. 

The Company documents all derivative financial instruments that are formally designated as hedging transactions at the inception 
of  the  hedging  relationship,  in  accordance  with  the  Company’s  risk  management  policies.  The  effectiveness  of  the  hedging 
relationship is evaluated, both at inception of the hedge and on an ongoing basis. 

The  Company  periodically  enters  into  commodity  price  contracts  to  manage  anticipated  sales  and  purchases  of  crude  oil  and 
natural gas in order to protect its cash flow for its capital expenditure programs. The effective portion of changes in the fair value of 
derivative commodity price contracts formally designated as cash flow hedges is initially recognized in other comprehensive income 
and is reclassified to risk management activities in net earnings in the same period or periods in which the commodity is sold or 
purchased. The ineffective portion of changes in the fair value of these designated contracts is recognized in risk management 
activities in net earnings. All changes in the fair value of non-designated crude oil and natural gas commodity price contracts are 
recognized in risk management activities in net earnings. 

The Company periodically enters into interest rate swap contracts to manage its fixed to floating interest rate mix on certain of its 
long-term debt. The interest rate swap contracts require the periodic exchange of payments without the exchange of the notional 
principal amounts on which the payments are based. Changes in the fair value of interest rate swap contracts designated as fair 
value hedges and corresponding changes in the fair value of the hedged long-term debt are recognized in interest expense in net 
earnings. Changes in the fair value of non-designated interest rate swap contracts are recognized in risk management activities in 
net earnings. 

Cross  currency  swap  contracts  are  periodically  used  to  manage  currency  exposure  on  US  dollar  denominated  long-term  debt. 
The cross currency swap contracts require the periodic exchange of payments with the exchange at maturity of notional principal 
amounts on which the payments are based. Changes in the fair value of the foreign exchange component of cross currency swap 
contracts designated as cash flow hedges related to the notional principal amounts are recognized in foreign exchange gains and 
losses in net earnings. The effective portion of changes in the fair value of the interest rate component of cross currency swap 
contracts  designated  as  cash  flow  hedges  is  initially  recognized  in  other  comprehensive  income  and  is  reclassified  to  interest 
expense when realized, with the ineffective portion recognized in risk management activities in net earnings. Changes in the fair 
value of non-designated cross currency swap contracts are recognized in risk management activities in net earnings. 

Realized gains or losses on the termination of financial instruments that have been designated as cash flow hedges are deferred 
under accumulated other comprehensive income on the consolidated balance sheets and amortized into net earnings in the period 
in which the underlying hedged items are recognized. In the event a designated hedged item is sold, extinguished or matures prior 
to the termination of the related derivative instrument, any unrealized derivative gain or loss is recognized in net earnings. Realized 
gains or losses on the termination of financial instruments that have not been designated as hedges are recognized in net earnings.

Upon  termination  of  an  interest  rate  swap  designated  as  a  fair  value  hedge,  the  interest  rate  swap  is  derecognized  on  the 
consolidated balance sheets and the related long-term debt hedged is no longer revalued for subsequent changes in fair value.  
The  fair  value  adjustment  on  the  long-term  debt  at  the  date  of  termination  of  the  interest  rate  swap  is  amortized  to  interest 
expense over the remaining term of the long-term debt. 

Foreign  currency  forward  contracts  are  periodically  used  to  manage  foreign  currency  cash  requirements.  The  foreign  currency 
forward  contracts  involve  the  purchase  or  sale  of  an  agreed  upon  amount  of  US  dollars  at  a  specified  future  date  at  forward 
exchange  rates.  Changes  in  the  fair  value  of  foreign  currency  forward  contracts  designated  as  cash  flow  hedges  are  initially 
recorded in other comprehensive income and are reclassified to foreign exchange gains and losses when realized. Changes in the 
fair value of non-designated foreign currency forward contracts are recognized in risk management activities in net earnings. 

Embedded derivatives are derivatives that are included in a non-derivative host contract. Embedded derivatives are recorded at 
fair value separately from the host contract when their economic characteristics and risks are not clearly and closely related to the 
host contract.

2012 ANNUAL REPORT

(S)  Comprehensive Income

Comprehensive  income  is  comprised  of  the  Company’s  net  earnings  and  other  comprehensive  income.  Other  comprehensive 
income includes the effective portion of changes in the fair value of derivative financial instruments designated as cash flow hedges 
and foreign currency translation gains and losses arising from the net investment in foreign operations that do not have a Canadian 
dollar functional currency. Other comprehensive income is shown net of related income taxes.

(T)   Per Common Share Amounts 

The Company calculates basic earnings per common share by dividing net earnings by the weighted average number of common 
shares outstanding during the period. As the Company’s Option Plan allows for the settlement of stock options in either cash or 
shares at the option of the holder, diluted earnings per common share is calculated using the more dilutive of cash settlement or 
share settlement under the treasury stock method. 

(U)  Share Capital

Common shares are classified as equity. Costs directly attributable to the issue of new shares or options are included in equity 
as a deduction from proceeds, net of tax. When the Company acquires its own common shares, share capital is reduced by the 
average carrying value of the shares purchased. The excess of the purchase price over the average carrying value is recognized as 
a reduction of retained earnings. Shares are cancelled upon purchase. 

(V)  Dividends

Dividends  on  common  shares  are  recognized  in  the  Company’s  financial  statements  in  the  period  in  which  the  dividends  are 
approved by the Board of Directors.

2.   ACCOUNTING STANDARDS ISSUED BUT NOT YET APPLIED 

In May 2011, the IASB issued the following new accounting standards, which are required to be adopted effective January 1, 2013:

IFRS  10  “Consolidated  Financial  Statements”  replaces  IAS  27  “Consolidated  and  Separate  Financial  Statements”  
(IAS  27  still  contains  guidance  for  Separate  Financial  Statements)  and  Standing  Interpretations  Committee  (“SIC”)  12 
“Consolidation  –  Special  Purpose  Entities”.  IFRS  10  establishes  the  principles  for  the  presentation  and  preparation  of 
consolidated  financial  statements.  The  standard  defines  the  principle  of  control  and  establishes  control  as  the  basis  for 
consolidation, as well as providing guidance on how to apply the control principle to determine whether an investor controls 
an investee. 

IFRS  11  “Joint  Arrangements”  replaces  IAS  31  “Interests  in  Joint  Ventures”  and  SIC  13  “Jointly  Controlled  Entities  –  
Non-Monetary Contributions by Venturers”. The new standard defines two types of joint arrangements, joint operations and 
joint ventures. In a joint operation, the parties with joint control have rights to the assets and obligations for the liabilities of 
the joint arrangement and are required to recognize their proportionate interest in the assets, liabilities, revenues and expenses 
of the joint arrangement. In a joint venture, the parties have an interest in the net assets of the arrangement and are required 
to apply the equity method of accounting. 

IFRS 12 “Disclosure of Interests in Other Entities”. The standard includes disclosure requirements for investments in subsidiaries, 
joint arrangements, associates and unconsolidated structured entities. This standard does not impact the Company’s accounting 
for investments in other entities, but may impact the related disclosures.

  Adoption of the above standards is not expected to result in a significant accounting change to the Company’s consolidated 

financial statements, but may impact the related disclosures.

In May 2011, the IASB also issued IFRS 13 “Fair Value Measurement”, effective January 1, 2013, which provides guidance on how 
fair value should be applied where its use is already required or permitted by other standards within IFRS. The standard includes 
a definition of fair value and a single source of fair value measurement and disclosure requirements for use across all IFRSs that 
require or permit the use of fair value. The Company will be required to include its own credit risk in measuring the carrying amount 
of a risk management liability. In addition, the new standard may impact certain fair value disclosures.

CANADIAN NATURAL

2012 ANNUAL REPORT

69

 
 
 
The Company is required to adopt IFRS 9, “Financial Instruments”, effective January 1, 2015, with earlier adoption permitted. IFRS 
9 replaces existing requirements included in IAS 39, “Financial Instruments - Recognition and Measurement”. The new standard 
replaces the multiple classification and measurement models for financial assets and liabilities with a new model that has only two 
categories: amortized cost and fair value through profit and loss. Under IFRS 9, fair value changes due to credit risk for liabilities 
designated at fair value through profit and loss would generally be recorded in other comprehensive income. The Company is 
currently assessing the impact of this new standard on its consolidated financial statements.

In  June  2011,  the  IASB  issued  amendments  to  IAS  1  “Presentation  of  Financial  Statements”  that  require  items  of  other 
comprehensive income that may be reclassified to net earnings to be grouped together. The amendments also require that items 
in other comprehensive income and net earnings be presented as either a single statement or two consecutive statements. The 
standard is effective for fiscal years beginning on or after July 1, 2012. Adoption of this amended standard is not expected to result 
in a significant change in the presentation of the Company’s consolidated financial statements.

In October 2011, the IASB issued IFRS Interpretation Committee (“IFRIC”) 20 “Stripping Costs in the Production Phase of a Surface 
Mine”. The IFRIC requires overburden removal costs during the production phase to be capitalized and depreciated if the Company 
can demonstrate that probable future economic benefits will be realized, the costs can be reliably measured, and the Company can 
identify the component of the ore body for which access has been improved. The IFRIC is effective for fiscal periods beginning on 
or after January 1, 2013. Adoption of this standard is not expected to result in a significant change to the Company’s consolidated 
financial statements.

3.   CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS 

The Company has made estimates, assumptions and judgements regarding certain assets, liabilities, revenues and expenses in the 
preparation of the consolidated financial statements, primarily related to unsettled transactions and events as of the date of the 
consolidated financial statements. Accordingly, actual results may differ from estimated amounts. The estimates, assumptions and 
judgements that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the 
next financial year are addressed below.

(A)  Crude Oil and Natural Gas Reserves

Purchase  price  allocations,  depletion,  depreciation  and  amortization,  and  amounts  used  in  impairment  calculations  are  based 
on  estimates  of  crude  oil  and  natural  gas  reserves.  Reserve  estimates  are  based  on  engineering  data,  estimated  future  prices, 
expected future rates of production and the timing of future capital expenditures, all of which are subject to many uncertainties, 
interpretations and judgements. The Company expects that, over time, its reserve estimates will be revised upward or downward 
based on updated information such as the results of future drilling, testing and production levels, and may be affected by changes 
in commodity prices. 

(B)  Asset Retirement Obligations

The  Company  provides  for  asset  retirement  obligations  on  its  property,  plant  and  equipment  based  on  current  legislation  and 
operating  practices.  Estimated  future  costs  include  assumptions  on  dates  of  future  abandonment  and  technological  advances 
and estimates of future inflation rates and discount rates. Actual costs may vary from the estimated provision due to changes in 
environmental legislation, the impact of inflation, changes in technology, changes in operating practices, and changes in the date 
of abandonment due to changes in reserve life, and may have a material impact on the estimated provision.

(C)  Income Taxes

The Company is subject to income taxes in numerous legal jurisdictions. Accounting for income taxes requires the Company to 
interpret  frequently  changing  laws  and  regulations,  including  changing  income  tax  rates,  and  make  certain  judgements  with 
respect to the application of tax law, estimating the timing of temporary difference reversals, and estimating the realizability of 
tax  assets.  There  are  many  transactions  and  calculations  for  which  the  ultimate  tax  determination  is  uncertain.  The  Company 
recognizes liabilities for potential tax audit issues based on assessments of whether additional taxes will likely be due.

(D)  Fair Value of Derivatives and Other Financial Instruments

The  fair  value  of  financial  instruments  that  are  not  traded  in  an  active  market  is  determined  using  valuation  techniques.  
The  Company  uses  its  judgement  to  select  a  variety  of  methods  and  make  assumptions  that  are  primarily  based  on  market 
conditions existing at the end of each reporting period. The Company uses directly and indirectly observable inputs in measuring 
the value of financial instruments that are not traded in active markets, including quoted commodity prices and volatility, interest 
rate yield curves and foreign exchange rates.

2012 ANNUAL REPORT

(E)   Purchase Price Allocations

Purchase prices related to business combinations and asset acquisitions are allocated to the underlying acquired assets and liabilities 
based  on  their  estimated  fair  value  at  the  time  of  acquisition.  The  determination  of  fair  value  requires  the  Company  to  make 
estimates, assumptions and judgements regarding future events. The allocation process is inherently subjective and impacts the 
amounts assigned to individually identifiable assets and liabilities, including the fair value of crude oil and natural gas properties. 
As a result, the purchase price allocation impacts the Company’s reported assets and liabilities and future net earnings due to the 
impact on future depletion, depreciation, and amortization expense and impairment tests.

(F)   Share-Based Compensation

The Company has made various assumptions in estimating the fair values of the stock options granted under the Option Plan, 
including expected volatility, expected exercise timing and future forfeiture rates. At each period end, stock options outstanding 
are remeasured for changes in the fair value of the liability. 

(G)  Identification of CGUs

CGUs are defined as the lowest grouping of integrated assets that generate identifiable cash inflows that are largely independent 
of the cash inflows of other assets or groups of assets. The classification of assets into CGUs requires significant judgement and 
interpretations with respect to the integration between assets, the existence of active markets, shared infrastructures, and the way 
in which management monitors the Company’s operations.

(H)  Impairment of Assets

The recoverable amount of a CGU or an individual asset has been determined as the higher of the CGU’s or the asset’s fair value 
less costs to sell and its value in use. These calculations require the use of estimates and assumptions and are subject to change 
as new information becomes available including information on future commodity prices, expected production volumes, quantity 
of reserves, discount rates and income taxes as well as future development and operating costs. Changes in assumptions used in 
determining the recoverable amount could affect the carrying value of the related assets and CGU’s.

(I)   Contingencies

Contingencies are subject to measurement uncertainty as the related financial impact will only be confirmed by the outcome of a 
future event. The assessment of contingencies requires the application of judgements and estimates including the determination 
of  whether  a  present  obligation  exists  and  the  reliable  estimation  of  the  timing  and  amount  of  cash  flows  required  to  settle  
the contingency.

In addition, the Company has capitalized costs to date of $1,021 million (2011 – $528 million) related to the development of the Kirby 
Thermal Oil Sands Project which are not subject to depletion.

During 2012, the Company acquired a number of producing crude oil and natural gas assets in the North American Exploration and 
Production segment for total cash consideration of $144 million (2011 – $1,012 million; 2010 – $1,482 million), net of associated 
asset retirement obligations of $12 million (2011 – $79 million; 2010 – $22 million). Interests in jointly controlled assets were acquired 
with full tax basis. No working capital or debt obligations were assumed.

The  Company  capitalizes  construction  period  interest  for  qualifying  assets  based  on  costs  incurred  and  the  Company’s  cost  of 
borrowing. Interest capitalization to a qualifying asset ceases once construction is substantially complete and the asset is available for 
its intended use. During 2012, pre-tax interest of $98 million was capitalized to property, plant and equipment (2011 – $59 million; 
2010 – $28 million) using a capitalization rate of 4.8% (2011 – 4.7%; 2010 – 4.9%).

Non-current liabilities represent interim borrowings by Redwater under credit facilities totaling $600 million which mature no later 
than December 2017. These facilities are secured by a floating charge on the assets of Redwater with a mandatory repayment 
required from future financing proceeds. At maturity, under its processing agreement, the Company would be obligated to pay 
its 25% pro rata share of any shortfall.

Redwater has entered into various agreements related to the engineering and procurement of the Project. These contracts can be 
cancelled by Redwater upon notice without penalty, subject to the costs incurred up to and in respect of the cancellation.

Bank Credit Facilities

As at December 31, 2012, the Company had in place unsecured bank credit facilities of $4,724 million, comprised of:

  a $200 million demand credit facility;

  a revolving syndicated credit facility of $3,000 million maturing June 2015;

  a revolving syndicated credit facility of $1,500 million maturing June 2016; and

  a £15 million demand credit facility related to the Company’s North Sea operations.

During 2012, the $1,500 million revolving syndicated credit facility was extended to June 2016. Each of the $3,000 million and 
$1,500 million facilities is extendible annually for one-year periods at the mutual agreement of the Company and the lenders.  
If the facilities are not extended, the full amount of the outstanding principal would be repayable on the maturity date. Borrowings 
under these facilities may be made by way of pricing referenced to Canadian dollar or US dollar bankers’ acceptances, or LIBOR, 
US base rate or Canadian prime loans. 

The  Company’s  weighted  average  interest  rate  on  bank  credit  facilities  outstanding  as  at  December  31,  2012,  was  2.2%  
(December  31,  2011  –  2.2%),  and  on  long-term  debt  outstanding  for  the  year  ended  December  31,  2012  was  4.8%  
(December 31, 2011 – 4.7%). 

In addition to the outstanding debt, letters of credit and financial guarantees aggregating $467 million, including an $87 million 
financial guarantee related to Horizon and $276 million of letters of credit related to North Sea operations, were outstanding at 
December 31, 2012. Subsequent to December 31, 2012, the letters of credit related to North Sea operations were increased to  
$347 million.

Medium-Term Notes

During  2012,  the  Company  issued  $500  million  of  3.05%  medium-term  notes  due  June  2019.  After  issuing  these  securities, 
the Company has $2,500 million remaining on its outstanding $3,000 million base shelf prospectus that allows for the issue of 
medium-term notes in Canada, which expires in November 2013. If issued, these securities will bear interest as determined at the 
date of issuance. 

US Dollar Debt Securities

During 2012, the Company repaid US$350 million of 5.45% unsecured notes.

During 2011, the Company repaid US$400 million of 6.70% unsecured notes and issued US$1,000 million of unsecured notes 
under the US base shelf prospectus, comprised of US$500 million of 1.45% unsecured notes due November 2014 and US$500 
million of 3.45% unsecured notes due November 2021. Concurrently, the Company entered into cross currency swaps to fix the 
Canadian dollar interest and principal repayment amounts on the US$500 million of 3.45% unsecured notes due November 2021 
at 3.96% and C$511 million (note 17).

The Company has US$2,000 million remaining on its outstanding US$3,000 million base shelf prospectus that allows for the issue 
of US dollar debt securities in the United States, which expires in November 2013. If issued, these securities will bear interest as

Current income taxes recognized in each operating segment will vary depending upon available income tax deductions related to 
the nature, timing and amount of capital expenditures incurred in any particular year.

During 2012, the UK government enacted legislation to restrict the combined corporate and supplementary income tax relief on 
UK North Sea decommissioning expenditures to 50%. As a result of the income tax rate change, the Company’s deferred income 
tax liability was increased by $58 million.

During 2011, the UK government enacted legislation to increase the supplementary income tax rate charged on profits from UK 
North Sea crude oil and natural gas production, increasing the combined corporate and supplementary income tax rate from 50% 
to 62%. As a result of the income tax rate change, the Company’s deferred income tax liability was increased by $104 million. 

During 2011, the Canadian Federal government enacted legislation to implement several taxation changes. These changes include 
a requirement that, beginning in 2012, partnership income must be included in the taxable income of each corporate partner 
based on the tax year of the partner, rather than the fiscal year of the partnership. The legislation includes a five-year transition 
provision and has no impact on net earnings.

2012 ANNUAL REPORT

 
During 2010, deferred income tax expense included a charge of $132 million related to enacted changes in Canada to the taxation 
of stock options surrendered by employees for cash. 

The Company files income tax returns in the various jurisdictions in which it operates. These tax returns are subject to periodic 
examinations in the normal course by the applicable tax authorities. The tax returns as prepared may include filing positions that 
could be subject to differing interpretations of applicable tax laws and regulations, which may take several years to resolve. The 
Company does not believe the ultimate resolution of these matters will have a material impact upon the Company’s results of 
operations, financial position or liquidity.

Deferred income tax assets are recognized for temporary differences to the extent that the realization of the related tax benefit 
through future taxable profits is probable. The Company did not recognize deferred income tax assets with respect to taxable 
capital loss carryforwards in excess of $1,000 million in North America, which can be carried forward indefinitely and only applied 
against future taxable capital gains.

Deferred  income  tax  liabilities  have  not  been  recognized  on  the  unremitted  net  earnings  of  wholly  controlled  subsidiaries.  
The  Company  is  able  to  control  the  timing  and  amount  of  distributions  and  no  taxes  are  payable  on  distributions  from  these 
subsidiaries provided that the distributions remain within certain limits.

During  2012,  the  Company  amended  its  Articles  by  special  resolution  of  the  shareholders,  changing  the  designation  of  its  
Class 1 preferred shares to “Preferred Shares” which may be issuable in series. If issued, the number of shares in each series, and 
the designation, rights, privileges, restrictions and conditions attached to the shares will be determined by the Board of Directors 
of the Company.

Dividend Policy

The Company has paid regular quarterly dividends in January, April, July and October of each year since 2001. The dividend policy 
undergoes periodic review by the Board of Directors and is subject to change.

On March 6 , 2013, the Board of Directors set the regular quarterly dividend at $0.125 per common share (2012 – $0.105 per 
common share; 2011 – $0.09 per common share).

Normal Course Issuer Bid

In 2012, the Company announced a Normal Course Issuer Bid to purchase, through the facilities of the Toronto Stock Exchange 
and  the  New  York  Stock  Exchange,  during  the  twelve  month  period  commencing  April  2012  and  ending  April  2013,  up  to 
55,027,447 common shares. The Company’s Normal Course Issuer Bid announced in 2011 expired April 2012.

During  2012,  the  Company  purchased  for  cancellation  11,012,700  common  shares  (2011  –  3,071,100  common  shares;  
2010 – 2,000,000 common shares) at a weighted average price of $28.91 per common share (2011 – $33.68 per common share; 
2010 – $33.77 per common share), for a total cost of $318 million (2011 – $104 million; 2010 – $68 million). Retained earnings 
were  reduced  by  $281  million  (2011  –  $94  million;  2010  –  $62  million),  representing  the  excess  of  the  purchase  price  of  the 
common shares over their average carrying value.

Share Split

The  Company’s  shareholders  passed  a  Special  Resolution  subdividing  the  common  shares  of  the  Company  on  a  two-for-one 
basis at the Company’s Annual and Special Meeting held on May 6, 2010 with such subdivision taking effect on May 21, 2010.  
All common share, per common share, and stock option amounts were restated to reflect the common share split. 

Stock Options

The Company’s Option Plan provides for the granting of stock options to employees. Stock options granted under the Option Plan 
have terms ranging from five to six years to expiry and vest over a five-year period. The exercise price of each stock option granted 
is determined at the closing market price of the common shares on the Toronto Stock Exchange on the day prior to the grant. Each 
stock option granted provides the holder the choice to purchase one common share of the Company at the stated exercise price or 
receive a cash payment equal to the difference between the stated exercise price and the market price of the Company’s common 
shares on the date of surrender of the stock option. 

The Option Plan is a “rolling 9%” plan, whereby the aggregate number of common shares that may be reserved for issuance under 
the plan shall not exceed 9% of the common shares outstanding from time to time. 

The following table summarizes information relating to stock options outstanding at December 31, 2012 and 2011:

The  Company  does  not  have  any  externally  imposed  regulatory  capital  requirements  for  managing  capital.  The  Company  has 
defined its capital to mean its long-term debt and consolidated shareholders’ equity, as determined at each reporting date. 

The  Company’s  objectives  when  managing  its  capital  structure  are  to  maintain  financial  flexibility  and  balance  to  enable  the 
Company to access capital markets to sustain its on-going operations and to support its growth strategies. The Company primarily 
monitors capital on the basis of an internally derived financial measure referred to as its “debt to book capitalization ratio”, which 
is the arithmetic ratio of current and long-term debt divided by the sum of the carrying value of shareholders’ equity plus current 
and long-term debt. The Company’s internal targeted range for its debt to book capitalization ratio is 25% to 45%. This range may 
be exceeded in periods when a combination of capital projects, acquisitions, or lower commodity prices occurs. The Company may 
be below the low end of the targeted range when cash flow from operating activities is greater than current investment activities. 
At December 31, 2012, the ratio was within the target range at 26%. 

Readers are cautioned that the debt to book capitalization ratio is not defined by IFRS and this financial measure may not be 
comparable to similar measures presented by other companies. Further, there are no assurances that the Company will continue to 
use this measure to monitor capital or will not alter the method of calculation of this measure in the future.

The Company’s outstanding commodity derivative financial instruments are expected to be settled monthly based on the applicable 
index pricing for the respective contract month. 

Interest rate risk management

The Company is exposed to interest rate price risk on its fixed rate long-term debt and to interest rate cash flow risk on its floating 
rate long-term debt. The Company periodically enters into interest rate swap contracts to manage its fixed to floating interest rate 
mix on long-term debt. The interest rate swap contracts require the periodic exchange of payments without the exchange of the 
notional principal amounts on which the payments are based. At December 31, 2012, the Company had no interest rate swap 
contracts outstanding.

Foreign currency exchange rate risk management

The Company is exposed to foreign currency exchange rate risk in Canada primarily related to its US dollar denominated long-
term debt and working capital. The Company is also exposed to foreign currency exchange rate risk on transactions conducted 
in other currencies and in the carrying value of its foreign subsidiaries. The Company periodically enters into cross currency swap 
contracts and foreign currency forward contracts to manage known currency exposure on US dollar denominated long-term debt 
and working capital. The cross currency swap contracts require the periodic exchange of payments with the exchange at maturity 
of notional principal amounts on which the payments are based. At December 31, 2012, the Company had the following cross 
currency swap contracts outstanding:

All  cross  currency  swap  derivative  financial  instruments  designated  as  hedges  at  December  31,  2012  were  classified  as  cash  
flow hedges.

In  addition  to  the  cross  currency  swap  contracts  noted  above,  at  December  31,  2012,  the  Company  had  US$2,821  million  of 
foreign currency forward contracts outstanding, with terms of approximately 30 days or less. 

Financial instrument sensitivities

The following table summarizes the annualized sensitivities of the Company’s 2012 net earnings and other comprehensive income 
to changes in the fair value of financial instruments outstanding as at December 31, 2012, resulting from changes in the specified 
variable, with all other variables held constant. These sensitivities are prepared on a different basis than those sensitivities disclosed 
in the Company’s other continuous disclosure documents, are limited to the impact of changes in a specified variable applied to 
financial instruments only and do not represent the impact of a change in the variable on the operating results of the Company 
taken  as  a  whole.  Further,  these  sensitivities  are  theoretical,  as  changes  in  one  variable  may  contribute  to  changes  in  another 
variable, which may magnify or counteract the sensitivities. In addition, changes in fair value generally cannot be extrapolated 
because the relationship of a change in an assumption to the change in fair value may not be linear.

b)  Credit risk

Credit risk is the risk that a party to a financial instrument will cause a financial loss to the Company by failing to discharge an obligation.

Counterparty credit risk management

The Company’s accounts receivable are mainly with customers in the crude oil and natural gas industry and are subject to normal 
industry credit risks. The Company manages these risks by reviewing its exposure to individual companies on a regular basis and 
where appropriate, ensures that parental guarantees or letters of credit are in place to minimize the impact in the event of default. 
At December 31, 2012, substantially all of the Company’s accounts receivable were due within normal trade terms.

The  Company  is  also  exposed  to  possible  losses  in  the  event  of  nonperformance  by  counterparties  to  derivative  financial 
instruments; however, the Company manages this credit risk by entering into agreements with counterparties that are substantially 
all investment grade financial institutions and other entities. At December 31, 2012, the Company had net risk management assets 
of $18 million with specific counterparties related to derivative financial instruments (December 31, 2011 – $nil).

The carrying amount of financial assets approximates the maximum credit exposure. 

c)  Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting obligations associated with financial liabilities.

Management of liquidity risk requires the Company to maintain sufficient cash and cash equivalents, along with other sources of 
capital, consisting primarily of cash flow from operating activities, available credit facilities, and access to debt capital markets, to 
meet obligations as they become due. The Company believes it has adequate bank credit facilities to provide liquidity to manage 
fluctuations in the timing of the receipt and/or disbursement of operating cash flows.

The maturity dates for financial liabilities are as follows:

Accounts payable

Accrued liabilities

1 year

2 to less

without penalty, subject to the costs incurred up to and in respect of the cancellation.

The Company is defendant and plaintiff in a number of legal actions arising in the normal course of business. In addition, the 
Company is subject to certain contractor construction claims. The Company believes that any liabilities that might arise pertaining 
to any such matters would not have a material effect on its consolidated financial position.

20.  SEGMENTED INFORMATION 

The Company’s exploration and production activities are conducted in three geographic segments: North America, North Sea and 

Offshore Africa. These activities include the exploration, development, production and marketing of crude oil, natural gas liquids 

and natural gas. 

The Company’s Oil Sands Mining and Upgrading activities are reported in a separate segment from exploration and production 

activities. The bitumen in the segment is recovered through mining operations. 

Midstream  activities  include  the  Company’s  pipeline  operations,  an  electricity  co-generation  system  and  Redwater.  Production 
activities that are not included in the above segments are reported in the segmented information as other. Inter-segment eliminations 
include internal transportation and electricity charges.

Sales between segments are made at prices that approximate market prices, taking into account the volumes involved. Segment 
revenue and segment results include transactions between business segments. These transactions and any unrealized profits and 
losses are eliminated on consolidation, unless unrealized losses provide evidence of an impairment of the asset transferred. Sales 
to external customers are based on the location of the seller.

Operating segments are reported in a manner consistent with the internal reporting provided to senior management.

SUPPLEMENTARY OIL & GAS INFORMATION (UNAUDITED)

This supplementary crude oil and natural gas information is provided in accordance with the United States Financial Accounting 
Standards Board (“FASB”) Topic 932 – “Extractive Activities – Oil and Gas” and where applicable, financial information is prepared 
in accordance with International Financial Reporting Standards (“IFRS”). In addition, comparative financial information for 2010 
has been restated from generally accepted accounting principles in the United States to reflect the adoption of IFRS.

For the years ended December 31, 2012, 2011 and 2010, the Company filed its reserves information under National Instrument 
51-101 – “Standards of Disclosure of Oil and Gas Activities” (“NI 51-101”), which prescribes the standards for the preparation and 
disclosure of reserves and related information for companies listed in Canada. For years prior to 2010, the Company was granted 
an exemption from certain provisions of NI 51-101 allowing the Company to substitute SEC requirements under Regulations S-K 
and S-X for certain disclosures required under NI 51-101. Such exemption expired on December 31, 2010.

There are significant differences to the type of volumes disclosed and the basis from which the volumes are economically determined 
under the SEC requirements and NI 51-101. The SEC requires disclosure of net reserves, after royalties, using 12-month average 
prices and current costs; whereas NI 51-101 requires gross reserves, before royalties, using forecast prices and costs. Therefore the 
difference between the reported numbers under the two disclosure standards can be material.

For the purposes of determining proved crude oil and natural gas reserves for SEC requirements as at December 31, 2012, 2011, 
and 2010 the Company used the 12-month average price, defined by the SEC as the unweighted arithmetic average of the first-
day-of-the-month price for each month within the 12-month period prior to the end of the reporting period. The Company has 
used the following 12-month average benchmark prices to determine its 2012 reserves for SEC requirements.

NET PROVED CRUDE OIL AND NATURAL GAS RESERVES

The Company retains Independent Qualified Reserves Evaluators to evaluate the Company’s proved crude oil, bitumen, synthetic 
crude oil (“SCO”), natural gas liquids (“NGLs”) and natural gas reserves. 

For the years ended December 31, 2012, 2011, 2010, and 2009, the reports by GLJ Petroleum Consultants Ltd. covered 100% 
of the Company’s SCO reserves. With the inclusion of non-traditional resources within the definition of “oil and gas producing 
activities” in the SEC’s modernization of oil and gas reporting rules (“Final Rule”), effective January 1, 2010 these reserves 
volumes are included within the Company’s crude oil and natural gas reserves totals.

For  the  years  ended  December  31,  2012,  2011,  2010,  and  2009,  the  reports  by  Sproule  Associates  Limited  and  Sproule 
International Limited covered 100% of the Company’s bitumen, crude oil and NGLs, and natural gas reserves. 

Proved crude oil and natural gas reserves, as defined within the SEC’s Regulation S-X under the Final Rule, are the estimated quantities 
of oil and gas that geoscience and engineering data demonstrate with reasonable certainty to be economically producible, from a 
given date forward, from known reservoirs under existing economic conditions, operating methods and government regulations. 
Proved developed reserves are reserves that can be expected to be recovered from existing wells with existing equipment and 
operating methods or in which the cost of the required equipment is relatively minor compared to the cost of drilling a new well; 
and through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is 
by means not involving a well.

Estimates  of  crude  oil  and  natural  gas  reserves  are  subject  to  uncertainty  and  will  change  as  additional  information  regarding 
producing fields and technology becomes available and as future economic and operating conditions change.

(2)  Bitumen as defined by the SEC under the Final Rule, “is petroleum in a solid or semi-solid state in natural deposits with a viscosity greater than 10,000 centipoise 
measured at original temperature in the deposit and atmospheric pressure, on a gas free basis.” Under this definition, all the Company’s thermal and primary heavy 
crude oil reserves have been classified as bitumen.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS FROM PROVED  
CRUDE OIL AND NATURAL GAS RESERVES AND CHANGES THEREIN

The following standardized measure of discounted future net cash flows from proved crude oil and natural gas reserves has been 
computed using the 12-month average price, defined by the SEC as the unweighted arithmetic average of the first-day-of-the-
month price for each month within the 12-month period prior to the end of the reporting period, costs as at the balance sheet 
date and year-end statutory income tax rates. A discount factor of 10% has been applied in determining the standardized measure 
of discounted future net cash flows. The Company does not believe that the standardized measure of discounted future net cash 
flows will be representative of actual future net cash flows and should not be considered to represent the fair value of the crude 
oil and natural gas properties. Actual net cash flows will differ from the presented estimated future net cash flows due to several 
factors including:

Future production will include production not only from proved properties, but may also include production from probable 
and possible reserves;

Future production of crude oil and natural gas from proved properties will differ from reserves estimated;

Future production rates will vary from those estimated;

Future prices and costs rather than 12-month average prices and costs as at the balance sheet date will apply;

Economic factors such as interest rates, income tax rates, regulatory and fiscal environments and operating conditions will change;

Future estimated income taxes do not take into account the effects of future exploration and evaluation expenditures; and

Future development and asset retirement obligations will differ from those estimated.

Future net revenues, development, production and asset retirement obligation costs have been based upon the estimates referred 
to above. The following tables summarize the Company’s future net cash flows relating to proved crude oil and natural gas reserves 
based on the standardized measure as prescribed in FASB Topic 932 – “Extractive Activities – Oil and Gas”:

(1)  Restated to reflect two-for-one share splits in May 2010, May 2005 and May 2004.
(2)  Cash flow from operations is a non-GAAP measure that represents net earnings adjusted for non-cash items before working capital adjustments. The Company evaluates its performance based 

on cash flow from operations. Cash flow from operations may not be comparable to similar measures used by other companies.

(3)  Refer to the “Liquidity and Capital Resources” section of the MD&A for the definitions of these items.
(4)  Based upon company gross reserves (forecast prices and costs, before royalties), using year-end common shares outstanding. Excludes Horizon SCO reserves prior to 2009. Prior to 2010, 

Company gross reserves were prepared using constant prices and costs.

(5)  Calculated as the net present value of future net revenue of the Company’s total proved plus probable reserves prepared using forecast prices and costs discounted at 10%, as reported in the 
Company’s AIF, with $300/acre added for core unproved property ($250/acre for core undeveloped land from 2005 to 2009, $75/acre for core undeveloped land for all years prior to 2005), 
less net debt and using year end common shares outstanding. Net debt is the Company’s long-term debt plus/minus the working capital deficit/surplus. Excludes Horizon SCO reserves prior to 
2009. Future development costs and associated material well abandonment costs have been applied against the future net revenue.

(6)  2010 comparative figures have been restated in accordance with IFRS issued at December 31, 2011.
(7)  Comparative figures for years prior to 2010 are in accordance with Canadian GAAP as previously reported and may not be prepared on a basis consistent with IFRS as adopted.

Corporate Governance
Canadian Natural’s corporate governance practices and disclosure of those practices are in compliance with National Policy 58-201 Corporate Governance Guidelines 
and National Instrument 58-101 Disclosure of Corporate Governance Practices. Canadian Natural, as a “foreign private issuer” in the United States, may rely on home 
jurisdiction  listing  standards  for  compliance  with  most  of  the  New  York  Stock  Exchange  (“NYSE”)  Corporate  Governance  Listing  Standards  but  must  disclose  any 
significant differences between its corporate governance practices and those required for U.S. companies listed on the NYSE.

Canadian Natural follows Toronto Stock Exchange (“TSX”) rules with respect to shareholder approval of equity compensation plans and material revisions to such plans. 
TSX rules provide that only the creation of or material amendments to equity compensation plans which provide for new issuance of securities are subject to shareholder 
approval. However, the NYSE requires shareholder approval of all equity compensation plans whether they provide for the delivery of newly issued securities, or rely on 
securities acquired in the open market by the issuing company for the purposes of redistribution to plan beneficiaries, and material revisions to such plans. Canadian 
Natural has a share bonus plan pursuant to which common shares are purchased through the TSX. This is not a new issue of securities under the share bonus plan and 
under TSX rules the plan is not subject to shareholder approval. 

Canadian Natural has included as exhibits to its Annual Report on Form 40-F for the 2012 fiscal year filed with the United States Securities and Exchange Commission 
certificates of the Chief Executive Officer and Chief Financial Officer certifying as to disclosure controls and procedures and internal control over financial reporting.
