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.

Our ability to generate free cash flow while ensuring we 

economically develop production of high return projects is one of our 

main objectives. We are selective in the areas we operate, and are 

well-positioned to capture opportunities and generate strong returns.

We have an enormous resource base which we are committed to 

develop with prudence and discipline. Our proven effective strategy 

combined with the execution of our defined growth plan will deliver 

premium value to our shareholders.

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.

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.

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. 

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. 
CANADIAN NATURAL 2012 ANNUAL REPORT 7

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. 

Canadian Natural’s total overall production for 2012 averaged 

655 thousand barrels of oil equivalent per day, representing a 9% 

increase from 2011. As we transition to a longer life, low decline 

asset base, our strong experienced team remains focused on 

continuing to deliver on our proven and effective strategy. This, 

combined with our strong balance sheet, will allow us to withstand 

future commodity price volatility, while we increase our capacity to 

generate free cash flow and maximize shareholder value.

We remain committed to our strategy and focused on maximizing 

value, which enables us to deliver returns to our shareholders over 

the near, mid- and long-term. At Canadian Natural we are all 

shareholders, enabling us to remain focused, disciplined and driven. 

With this combination of our assets, team and strategy, Canadian 

Natural will remain a premium value, defined growth independent.

YEAR-END RESERVES

Determination of Reserves

For the year ended December 31, 2012 the Company retained 

Independent Qualified Reserves Evaluators (“Evaluators”), Sproule 

Associates Limited, Sproule International Limited (together as 

“Sproule”) and GLJ Petroleum Consultants Ltd. (“GLJ”), to evaluate 

and review all of the Company’s proved and proved plus probable 

reserves. Sproule evaluated the Company’s North America and 

International crude oil, bitumen, natural gas and NGL reserves. GLJ 

evaluated the Company’s Horizon synthetic crude oil reserves. The 

Evaluators conducted the evaluation and review in accordance with 

the standards contained in the Canadian Oil and Gas Evaluation 

Handbook (“COGE Handbook”). The reserves disclosure is presented 

in accordance with NI 51-101 requirements using forecast prices 

and escalated costs.

The Reserves Committee of the Company’s Board of Directors has 

met with and carried out independent due diligence procedures 

with the Evaluators as to the Company’s reserves.

accounted for 38% of the North America total proved reserves 

and proved undeveloped natural gas reserves accounted for 8% 

of the North America total proved reserves.

 Thermal oil Company Gross proved reserves increased 9% to 

1,066 million barrels primarily due to category transfers from 

probable undeveloped to proved undeveloped at Kirby North 

and new proved undeveloped additions at Primrose and Wolf 

Lake. Proved bitumen reserve additions and revisions were 

128 million barrels. Total proved plus probable bitumen 

reserves increased 23% to 2,122 million barrels primarily due 

to proved plus probable undeveloped additions at Primrose 

and Wolf Lake and probable undeveloped additions at Grouse.

(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.

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 
CANADIAN NATURAL 2012 ANNUAL REPORT 19

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. 

The following discussion and analysis refers primarily to the Company’s 2012 financial results compared to 2011 and 2010, unless 

otherwise indicated. In addition, this MD&A details the Company’s capital program and outlook for 2013. Additional information 

relating to the Company, including its quarterly MD&A for the year and three months ended December 31, 2012, its Annual 

Information Form for the year ended December 31, 2012, and its audited consolidated financial statements for the year ended 

December 31, 2012 is available on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. This MD&A is dated March 6, 2013.

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) Adjusted net earnings from operations is a non-GAAP measure that represents net earnings adjusted for certain items of a non-operational nature. The Company 

evaluates its performance based on adjusted net earnings from operations. The reconciliation “Adjusted Net Earnings from Operations” presents the after-tax 

effects of certain items of a non-operational nature that are included in the Company’s financial results. Adjusted net earnings from operations may not be 

comparable to similar measures presented by other companies.

(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. The Company considers cash flow from operations a key measure as it demonstrates the Company’s 

ability to generate the cash flow necessary to fund future growth through capital investment and to repay debt. The reconciliation “Cash Flow from Operations” 

presents certain non-cash items that are included in the Company’s financial results. Cash flow from operations may not be comparable to similar measures 

presented by other companies.

(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).

SUMMARY OF QUARTERLY RESULTS

The following is a summary of the Company’s quarterly results for the eight most recently completed quarters:

($ millions, except per common share amounts)

2011 Total Dec 31 Sep 30 Jun 30 Mar 31

Product sales $ 15,507 $ 4,788 $ 3,690 $ 3,727 $ 3,302

Net earnings $ 2,643 $ 832 $ 836 $ 929 $ 46

Net earnings per common share

– basic $ 2.41 $ 0.76 $ 0.76 $ 0.85 $ 0.04

– diluted $ 2.40 $ 0.76 $ 0.76 $ 0.84 $ 0.04

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.

Commodity Prices

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 

future net earnings, cash flow and capital projects. For additional details, refer to the “Greenhouse Gas and Other Air Emissions” 

section of this MD&A.

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%),

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.
28 CANADIAN NATURAL 2012 ANNUAL REPORT

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.

Realized crude oil and NGLs prices decreased 9% to average $70.24 per bbl for 2012 from $77.46 per bbl for 2011 

(2010 – $65.81 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.

The Company’s realized natural gas price decreased 35% to average $2.44 per Mcf for 2012 from $3.73 per Mcf for 2011 

(2010 – $4.08 per Mcf). The decrease in 2012 was primarily due to lower NYMEX and AECO benchmark pricing related to the 

impact of strong supply from US shale projects.

North America realized crude oil prices decreased 9% to average $65.54 per bbl for 2012 from $72.17 per bbl for 2011 

(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 

in-service date in 2017.

North Sea

North Sea realized crude oil prices increased 2% to average $110.75 per bbl for 2012 from $108.56 per bbl for 2011 

(2010 – $82.49 per bbl). Realized crude oil prices per bbl in any particular period are dependent on the terms of the various sales 

contracts, the frequency and timing of liftings of each field, and prevailing crude oil prices at the time of lifting. The slight increase 

in realized crude oil prices in the North Sea from 2011 was primarily due to higher Brent benchmark pricing, the impact of the 

weaker Canadian dollar, and the timing of liftings.

Offshore Africa

Offshore Africa realized crude oil prices increased 5% to average $111.18 per bbl for 2012 from $105.53 per bbl for 2011 

(2010 – $78.93 per bbl). Realized crude oil prices per bbl in any particular year are dependent on the terms of the various sales 

contracts, the frequency and timing of liftings of each field, and prevailing crude oil prices at the time of lifting. The increase in 

realized crude oil prices in Offshore Africa from 2011 was primarily due to the higher Brent benchmark pricing, the impact of the 

weaker Canadian dollar, and the timing of liftings.

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

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.

Segment earnings before taxes $ 48 $ 55 $ 49

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.

$/BOE (1) $ 1.13 $ 1.07 $ 0.92

(1) Amounts expressed on a per unit basis are based on sales volumes. 

Administration expense for 2012 increased from 2011 primarily due to higher staffing related costs and general corporate costs.

SHARE-BASED COMPENSATION

($ millions) 2012 2011 2010

(Recovery) expense $ (214) $ (102) $ 203

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).

Net loss (gain) $ 120 $ (27) $ (134)

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. 

Complete details related to outstanding derivative financial instruments at December 31, 2012 are disclosed in note 17 to the 

Company’s consolidated financial statements.

Net (gain) loss $ (49) $ 1 $ (163)

(1) Amounts are reported net of the hedging effect of cross currency swaps.

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).

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. 

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.

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

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.

During 2011, the Company sanctioned an 8 well drilling program at the Espoir field in Côte d’Ivoire. Preparations are ongoing 

and a drilling rig is on-site in preparation for the commencement of the drilling program in 2013. At the Olowi field in Gabon, 

approximately 1,500 bbl/d of production was shut in. The Company currently has a vessel on-site in Gabon assessing the operability 

of the midwater arch.

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 41

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 longterm 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.

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

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 

Company’s Annual Report.

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.
CANADIAN NATURAL 2012 ANNUAL REPORT 45

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.
46 CANADIAN NATURAL 2012 ANNUAL REPORT

For 2012, the Company’s capital expenditures included $204 million for abandonment expenditures (2011 – $213 million; 

2010 – $179 million). The Company’s estimated discounted ARO at December 31, 2012 was as follows:

($ millions) 2012 2011

Exploration and Production

North America $ 2,079 $ 1,862

North Sea 1,030 723

Offshore Africa 218 192

Oil Sands Mining and Upgrading 937 798

Midstream 2 2

$ 4,266 $ 3,577

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.
CANADIAN NATURAL 2012 ANNUAL REPORT 47

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.
48 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.
CANADIAN NATURAL 2012 ANNUAL REPORT 49

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.

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 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.

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 cogeneration 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. 
64 CANADIAN NATURAL 2012 ANNUAL REPORT

(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 65

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. 
66 CANADIAN NATURAL 2012 ANNUAL REPORT

(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.
CANADIAN NATURAL 2012 ANNUAL REPORT 67

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.
68 CANADIAN NATURAL 2012 ANNUAL REPORT

(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. 
CANADIAN NATURAL 2012 ANNUAL REPORT 69

(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.
70 CANADIAN NATURAL 2012 ANNUAL REPORT

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.
CANADIAN NATURAL 2012 ANNUAL REPORT 71

(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.

(1) During 2011, the Company derecognized certain property, plant and equipment related to the coker fire at Horizon in the amount of $411 million based 

on estimated replacement cost, net of accumulated depletion and depreciation of $15 million, resulting in an impairment charge of $396 million. 

For additional information, refer to note 10. 

Horizon project costs not subject to depletion 

At December 31, 2012 $ 2,066

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%).

Investment in North West Redwater Partnership $ 310 $ 321

Other 117 70

$ 427 $ 391

Other long-term assets include an investment in the 50% owned Redwater. The investment is accounted for using the equity 

method. Redwater has entered into an agreement to construct and operate a 50,000 barrel per day bitumen upgrader and refinery 

(the “Project”) under processing agreements that target to process 12,500 barrels per day of bitumen feedstock for the Company 

and 37,500 barrels per day of bitumen feedstock for the Alberta Petroleum Marketing Commission, an agent of the Government 

of Alberta, under a 30 year fee-for-service tolling agreement. During 2012, the Project received board sanction from Redwater and 

its partners.

The assets, liabilities, partners’ equity and equity loss related to Redwater and the Company’s 50% interest at December 31, 2012 

were comprised as follows: 

Redwater 

100% interest

Company 

50% interest

Current assets $ 40 $ 20

Non-current assets $ 810 $ 405

Current liabilities $ 68 $ 34

Non-current liabilities $ 162 $ 81

Partners’ equity $ 620 $ 310

Equity loss $ 18 $ 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.

CANADIAN NATURAL 2012 ANNUAL REPORT 75

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

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. 
CANADIAN NATURAL 2012 ANNUAL REPORT 79

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.

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.
80 CANADIAN NATURAL 2012 ANNUAL REPORT

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.

14. CAPITAL DISCLOSURES 

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.

Financial Risk Factors

a) Market risk

Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market 

prices. The Company’s market risk is comprised of commodity price risk, interest rate risk, and foreign currency exchange risk.

Commodity price risk management

The Company periodically uses commodity derivative financial instruments to manage its exposure to commodity price risk 

associated with the sale of its future crude oil and natural gas production and with natural gas purchases. At December 31, 2012, 

the Company had the following derivative financial instruments outstanding to manage its commodity price risk:

2013 and an additional 50,000 bbl/d of US$80 – US$132.18 Brent collars for the period July to December 2013.

During 2012, US$65 million of put option costs were settled.

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.
CANADIAN NATURAL 2012 ANNUAL REPORT 85

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 longterm 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:

Less than

1 year

1 to less 

than 2 years

2 to less 

than 5 years Thereafter

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.

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.

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 firstday-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.

The following table summarizes the Company’s proved and proved developed crude oil and natural gas reserves, net of royalties,

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-themonth 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”:

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.

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.
