  NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
  (unaudited) 

 1. REPORTING ENTITY AND DESCRIPTION OF THE BUSINESS  

Suncor
Energy Inc. (Suncor or the company) is an integrated energy company headquartered in Canada. Suncor's operations include oil sands development and upgrading, onshore and offshore oil and
gas production, petroleum refining, and product marketing primarily under the Petro-Canada brand. The consolidated financial statements of the company comprise the company and its subsidiaries and the
company's interests in associates and jointly controlled entities. 

The
address of the company's registered office is 150 - 6th Avenue S.W., Calgary, Alberta, Canada, T2P 3E3. 

 2. BASIS OF PREPARATION  

(a)  Statement of Compliance  

These condensed consolidated interim financial statements have been prepared in accordance with Canadian generally accepted accounting principles, specifically International
Accounting Standard 34 Interim Financial Reporting as issued by the International Accounting Standards Board. They are condensed as they do not include
all of the information required for full annual financial statements, and they should be read in conjunction with the consolidated financial statements for the year ended
December 31, 2011. 

The
policies applied in these condensed interim consolidated financial statements are based on International Financial Reporting Standards (IFRS) issued and outstanding as at April 30, 2012,
the date the Audit Committee approved these statements on behalf of the Board of Directors. 

(b)  Basis of Measurement  

The consolidated financial statements are prepared on a historical cost basis except as detailed in the accounting policies disclosed in the company's consolidated financial
statements for the year ended December 31, 2011. Those accounting policies have been applied consistently to all periods presented in these financial statements. 

(c)  Functional Currency and Presentation Currency  

These consolidated financial statements are presented in Canadian dollars, which is the company's functional currency. 

(d)  Use of Estimates and Judgment  

The timely preparation of financial statements requires that management make estimates and assumptions and use judgment. Accordingly, actual results may differ from estimated
amounts as future confirming events occur. Significant estimates and judgment used in the preparation of the financial statements are described in the company's consolidated financial statements for
the year ended December 31, 2011. 

 3. SEGMENTED INFORMATION  

The company's operating segments are determined based on differences in the nature of their operations, products and services. 

Intersegment
sales of crude oil and natural gas are accounted for at market values and included, for segmented reporting, in revenues of the segment making the transfer and expenses of the segment
receiving the transfer. Intersegment amounts are eliminated on consolidation.

 1. ADVISORIES  

 Basis of Presentation  

Unless otherwise noted, all financial information has been prepared in accordance with Canadian generally accepted accounting
principles (GAAP), specifically International Accounting Standard (IAS) 34 – Interim Financial Reporting as issued
by the International Accounting Standards Board, which is within Part 1 of the Canadian Institute of Chartered Accountants Handbook, which itself is within the framework of International
Financial Reporting Standards (IFRS). 

All
financial information is reported in Canadian dollars, unless otherwise noted. Production volumes are presented on a working-interest basis, before royalties, unless otherwise noted. Certain prior
year amounts in the Consolidated Statements of Comprehensive Income have been reclassified to conform to the current year's presentation. 

 Non-GAAP Financial Measures  

Certain financial measures in this MD&A – namely operating earnings, cash flow from operations,
return on capital employed (ROCE) and Oil Sands cash operating costs – are not prescribed by GAAP. Operating earnings and Oil Sands cash operating costs are
defined in the Non-GAAP Financial Measures Advisory section of this MD&A and reconciled to GAAP

measures
in the Segment Results and Analysis section of this MD&A. Cash flow from operations and ROCE are defined and reconciled to GAAP measures in the Non-GAAP Financial Measures
Advisory section of this MD&A. 

These
non-GAAP financial measures do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other companies. These
non-GAAP financial measures are included because management uses the information to analyze operating performance, leverage and liquidity, and should not be considered in isolation or as a
substitute for measures of performance prepared in accordance with GAAP.

 Risk Factors and Forward-Looking Information  

The company's financial and operational performance is potentially affected by a number of factors, including, but not limited to, the
volatility of commodity prices and exchange rate fluctuations; government regulation, including changes to royalty and income tax legislation; environmental regulation, including changes to climate
change and reclamation legislation; risks associated with operating in foreign countries, including geopolitical and other political risks; operating hazards and other uncertainties, including extreme
weather conditions, fires, explosions and oil spills; risks associated with the execution of major projects; reputational risk; permit approval; labour and materials supply; and other issues described
within the Advisory – Forward-Looking Information section of this MD&A. A more detailed discussion of the risk factors affecting the company is presented in the
Risk Factors section of Suncor's 2011 annual MD&A, which section is herein incorporated by reference. 

This
MD&A contains forward-looking information based on Suncor's current expectations, estimates, projections and assumptions. This information is subject to a number of risks and uncertainties,
including those discussed in this MD&A

Advisory – Forward-Looking Information section of this MD&A for information on the material risk factors and assumptions underlying our forward-looking
information. 

 Measurement Conversions  

Certain crude oil and natural gas liquids volumes have been converted to mcfe or mmcfe on the basis of one bbl to six mcf. Also,
certain natural gas volumes have been converted to boe or mboe on the same basis. Any figure presented in mcfe, mmcfe, boe or mboe may be misleading, particularly if used in isolation. A conversion
ratio of one bbl of crude oil or natural gas liquids to six mcf of natural gas is based on an energy equivalency conversion method primarily applicable at the burner tip and does not necessarily
represent value equivalency at the wellhead. Given
that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, conversion on a 6:1 basis may be
misleading as an indication of value. 

 2. FIRST QUARTER HIGHLIGHTS  

	•
	First quarter financial
results.   

	•
	Consolidated net earnings for the first quarter of 2012 were $1.457 billion, compared to $1.028 billion for
the first quarter of 2011.   

	•
	Operating earnings (1) for the first quarter of 2012 were $1.329 billion, compared to
$1.478 billion for the first quarter of 2011. Operating earnings were lower due primarily to lower upstream production volumes, higher royalties and higher depreciation in the Oil Sands
segment, partially offset by higher upstream price realizations.   

	•
	Cash flow from operations (1) was $2.426 billion for the first quarter of 2012, compared
to $2.393 billion for the first quarter of 2011.   

	•
	ROCE (1) (excluding major projects in progress) for the twelve months ended March 31,
2012 improved to 14.8%, compared to 12.5% for the twelve months ended March 31, 2011.   

	•
	Net debt at March 31, 2012 was $5.966 billion, compared to $6.976 billion at
December 31, 2011.   

	•
	Steve Williams to become chief executive
officer.  As announced on December 1, 2011, Rick George, the company's current Chief Executive Officer (CEO) is retiring effective
May 1, 2012. Suncor's President and Chief Operating Officer, Steve Williams, will succeed him as CEO. Mr. Williams joined Suncor in 2002 as Executive Vice President, Corporate
Development and Chief Financial Officer. He served as Executive Vice President, Oil Sands for four years where he was responsible for leading Suncor's oil sands operations through a significant period
of growth.   

	•
	Ramp up of production from Firebag Stage 3 expansion proceeding in line with
expectations. Bitumen production from the company's Firebag operations averaged 83,600 bbls/d and exited the first quarter of 2012 at approximately 96,000 bbls/d,
a 20% increase from the rate exiting the fourth quarter of 2011. Firebag bitumen production also increased due to infill wells completed in 2011 and optimization of steam generation from
Stage 3 facilities across the integrated Firebag complex.   

	•
	Increased Oil Sands production prior to Upgrader
2 outage.  Oil Sands (excluding Syncrude) achieved consecutive monthly record production levels in January and February, prior to
an operational issue in March with a fractionator at the Upgrader 2 facilities, which were taken offline for approximately five weeks for maintenance and restarted successfully in April.

earnings, cash flow from operations and ROCE are non-GAAP financial measures. See the Non-GAAP Financial Measures Advisory
section of this MD&A.

	•
	Power of Suncor's integrated business
model.  Canadian-based crude oil production, including Suncor's sweet and sour synthetic crude oil, traded at significant discounts to WTI
during the first quarter of 2012. Suncor's integration with inland refineries in the Refining and Marketing segment is recovering much of this decline in crude price realization through lower
feedstock costs. In addition, decreasing North American natural gas prices reduced cash flow from North America Onshore assets; however, this impact was more than offset by lower operating costs for
steam and power generation at Suncor's oil sands and refining facilities.   

	•
	Suncor continues its share repurchase
program.  In February, Suncor announced a plan to repurchase up to $1 billion of its common shares, continuing the program to
return value to shareholders that saw the company repurchase $500 million of its common shares in 2011. The company repurchased approximately 5.5 million common shares, returning
$183 million to shareholders during the first quarter of 2012. As at April 27, 2012, the company had repurchased approximately 4.3 million additional common shares, returning an
additional $134 million to shareholders.   

	•
	Dividend increase
approved.  Suncor's Board of Directors approved an 18% increase to the company's quarterly dividend to $0.13 per common share, from the
previous level of $0.11 per common share, beginning in the second quarter of 2012. The five-year compound annual growth rate of Suncor's dividends is 21%. 

 3. SUNCOR OVERVIEW  

Suncor Energy Inc. is an integrated energy company headquartered in Calgary, Alberta. The company has classified its operations into the
following segments: 

 OIL SANDS  

Suncor's Oil Sands segment, with assets located in northeast Alberta, recovers bitumen from mining and in situ operations and upgrades
the majority of this production into refinery feedstock, diesel fuel and byproducts. The Oil Sands segment includes: 

	•
	Oil Sands operations refer to Suncor's wholly owned and operated mining,
extraction, upgrading and in situ assets in the Athabasca oil sands region. Oil Sands operations consist of:  

	•
	Oil Sands Base operations include the Millennium and North Steepbank mining
and extraction operations, two integrated upgrading facilities known as Upgrader 1 and Upgrader 2, and the associated infrastructure for these assets – including
utilities, energy and reclamation facilities, such as Tailings Reduction Operations (TROTM) assets.   

	•
	In Situ operations include oil sands bitumen production from Firebag and
MacKay River and supporting infrastructure, such as central processing facilities and cogeneration units. The majority of In Situ production is upgraded by Oil Sands Base; however, the company's
marketing plan includes sales of bitumen when marketing conditions are favourable or as operating conditions at Oil Sands Base require.   

	•
	Oil Sands Ventures assets include the company's interests in significant
growth projects, including two where Suncor is the operator – the Fort Hills mining (40.8%) and the Voyageur upgrader (51%) projects, and one where Total E&P
Canada Ltd. (Total E&P) is the operator – the Joslyn North mining project (36.75%). Oil Sands Ventures also includes the company's 12% interest in the
Syncrude oil sands mining and upgrading joint venture. 

 EXPLORATION AND PRODUCTION  

Suncor's Exploration and Production segment consists of offshore operations off the east coast of Canada and in the North Sea, and
onshore operations in North America, Libya and Syria.  

	•
	East Coast Canada operations include Suncor's 37.675% working interest in

 Net Earnings  

Suncor's net earnings for the first quarter of 2012 were $1.457 billion, compared to $1.028 billion in the first quarter
of 2011. Net earnings were primarily affected by the same factors that influenced operating earnings described subsequently in this section of the MD&A. Other items affecting changes in net earnings
over the first quarter of 2012, compared with the first quarter of 2011, included: 

	•
	The after-tax unrealized foreign exchange gain on the revaluation of U.S. dollar denominated
long-term debt was $128 million in the first quarter of 2012, compared to $162 million in the first quarter of 2011.   

	•
	During the first quarter of 2011, the company disposed of assets resulting in after-tax losses of
$170 million, consisting of $89 million for the partial disposition of working interests in the Voyageur upgrader and Fort Hills mining projects, and $81 million for the sale of
non-core Exploration and Production assets.   

	•
	In the first quarter of 2011, the U.K. government announced an increase in the tax rate on oil and gas profits in
the North Sea that increased the statutory tax rate on Suncor's earnings in the U.K. from 50% to 59.3% in 2011 and 62% in future years. As a result, the company revalued its deferred income tax
balances, resulting in an increase to deferred income tax expense of $442 million. 

 Operating Earnings  

Suncor's consolidated operating earnings for the first quarter of 2012 were $1.329 billion, compared to $1.478 billion
in the first quarter of 2011.

	(1)
	Factors
represent after-tax variances and include the impacts of operating earnings adjustments. These factors are analyzed in the narrative
immediately subsequent to this bridge analysis. This bridge analysis is provided because management uses this presentation to analyze performance.

	(2)
	Calculated
based on production volumes for the Oil Sands and Exploration and Production segments and sales volumes for the Refining and Marketing segment.

	(3)
	Includes
upstream price realizations before royalties, refining and marketing margins, other operating revenues, and the net impacts of sales and purchases
of third-party crude.

	(4)
	The
Inventory variance factor reflects the opportunity cost of building production volumes in inventory or the additional margin earned by drawing down
inventory produced in previous periods. The calculation of the Inventory variance factor in this bridge analysis permits the company to present the Volume variance factor for upstream assets based on
production volumes, rather than based on sales volumes.

	(5)
	The
Operating Expense factor includes transportation expense, operating, selling and general expense and project start-up costs.

	(6)
	This
factor also includes changes in gains and losses on disposal of assets that are not operating earnings adjustments, changes in effective income tax
rates, and other income tax adjustments. 

Positive factors impacting operating earnings in the first quarter of 2012, compared to the same period in 2011, included: 

	•
	Average price realizations for crude oil were higher in the first quarter of 2012, due mainly to increases in the benchmark
prices for WTI and Brent crudes, partially offset by price discounts for Canadian-based crude oil production. Average price realizations increased 10% for Oil Sands segment sales and 17% for
Exploration and Production segment sales.   

	•
	Operating expenses were lower, due primarily to lower share-based compensation expense that reflected a smaller increase in
the company's common share price over the first quarter of 2012, compared with the first quarter of 2011. The impact on the company's operating segments of the $124 million
after-tax share-based compensation expense in the first quarter of 2012 was $64 million for Corporate, Energy Trading and Eliminations; $36 million for Oil Sands;
$18 million for Refining and Marketing; and $6 million for Exploration and Production. The first quarter of 2011 included a $212 million after-tax expense for share-
based compensation.   

	•
	Financing expense was lower in the first quarter of 2012, as the company capitalized a higher percentage of its borrowing
costs as part of the cost of major development assets and construction projects, resulting in lower interest expense. 

The
positive factors noted above were more than offset by the following: 

	•
	Production volumes for the Oil Sands segment decreased to 341,100 bbls/d from 360,600 bbls/d, due primarily
to an unplanned outage at the company's Upgrader 2 facilities.

       2012 First
Quarter    013

 
	•
	Production volumes for the Exploration and Production segment decreased to 221,200 boe/d from 240,700 boe/d,
primarily due to the divestiture of non-core assets throughout 2011, and the company declaring force majeure under its contractual obligations and suspending its operations in Syria in
December 2011.   

	•
	In the first quarter of 2011, the uplift to operating earnings with respect to the impact of a rising crude price
environment on refining margins was significantly higher than the uplift in the first quarter of 2012. In a rising crude price environment, inventories produced during periods of lower feedstock costs
are sold and replaced with inventories purchased at relatively higher feedstock costs.   

	•
	Royalties were higher in the first quarter of 2012, due mainly to higher benchmark prices and the prior year quarter
including higher allowable costs for Oil Sands Base capital projects.   

	•
	DD&A was higher in the first quarter of 2012, due mainly to recently commissioned assets for Oil Sands operations,
including the Firebag Stage 3 expansion, and charges related to modifications of the Millennium Naphtha Unit (MNU) hydrogen plant during the commissioning period. 

 Cash Flow from Operations  

Consolidated cash flow from operations for the first quarter of 2012 was $2.426 billion, compared to $2.393 billion in
the first quarter of 2011. The increase was mainly a result of higher upstream price realizations, partially offset by lower upstream production volumes and higher royalties. 

 Business Environment  

Commodity prices, refining crack spreads and foreign exchange rates are some of the most significant factors that affect the results
of Suncor's operations.

Suncor's sweet SCO price realizations are influenced primarily by changes in the price for WTI at Cushing. The average WTI price for the first quarter of 2012
increased to US$102.95/bbl, compared to US$94.10/bbl in the first quarter of 2011. Suncor's price realizations for SCO are also influenced by the supply and demand of sweet SCO from
Western Canada. 

Suncor
produces a specific grade of sour SCO, the price realizations for which are influenced by changes to various crude benchmarks including, but not limited to, Canadian par crude at Edmonton and
WCS at Hardisty, but which can also be affected by circumstances underlying spot sales required to manage inventory levels. Prices for Canadian par crude at Edmonton in the first quarter of 2012 also
increased, averaging $92.80/bbl, compared to $88.40/bbl in the first quarter of 2011. 

Bitumen
production that Suncor does not upgrade is blended with diluent to facilitate delivery on pipeline systems to customers. Net bitumen price realizations are, therefore, influenced by both
prices for Canadian heavy crude oil (WCS at Hardisty is a common reference) and prices for diluent (Condensate at Edmonton). Diluent is sourced primarily from the company's own upgrading and
refining facilities; however, purchases of diluent from third parties may be required when the company experiences operational outages. Bitumen price realizations can also be affected by bitumen
quality and spot sales to manage inventory levels. In the first quarter of 2012, average price realizations for bitumen relative to WTI were consistent with those realized in the first quarter of
2011, with increases in prices for WTI largely offset by increases in the price for diluent. 

Price
realizations for Suncor's crude sales basket relative to common benchmark crudes are also influenced by the demands of our refinery customers and distribution constraints on pipeline systems.
Compared to the fourth quarter of 2011, in the first quarter of 2012, prices for WTI increased, but prices for Canadian par crude at Edmonton decreased, sweet SCO traded at a discount to WTI, and the
light/heavy differential for Canadian-based crudes doubled. As a result, the overall average price realization for Suncor's Oil Sands production (excluding Syncrude) was WTI less Cdn$12.12/bbl,
compared to WTI plus Cdn$1.10/bbl in the fourth quarter of 2011. Suncor's integration with inland refineries in the Refining and Marketing segment is recovering much of this decline in crude price
realization through lower feedstock costs. 

Suncor's
price realizations for production from East Coast Canada and International assets are influenced primarily by the price for Brent crude. The average price for Brent crude in the first quarter
of 2012 increased to US$118.35/bbl from US$104.95/bbl in the first quarter of 2011. The average premium for Brent crude compared to WTI increased to US$15.40/bbl from $10.85/bbl. 

Suncor's
price realizations for North America Onshore natural gas production are primarily referenced to Alberta spot at AECO. The average AECO benchmark decreased to $2.50/mcf in the first quarter of
2012, from $3.80/mcf in the first quarter of 2011. 

Suncor's
refining margins are influenced primarily by 3-2-1 crack spreads, which are industry indicators approximating the gross margin on a barrel of crude oil that is
refined to produce gasoline and distillates, and by light/heavy and light/sour crude differentials, which indicate when more complex refineries can earn greater margins by processing less expensive,
heavier crudes. Crack spreads do not necessarily reflect the margins of a specific refinery because these benchmarks are calculated based off of WTI. Specific refinery margins are further impacted by
actual crude purchase costs, refinery configuration and refined product sales markets unique to that refinery's supply orbit. In the first quarter of 2012, crack spreads were higher than those from
the first quarter of 2011 in the major markets into which Suncor sells finished product. Prices for refined products reflected the higher priced Brent crude feedstock of coastal North American
markets, which continues to positively benefit Suncor's inland refineries (Sarnia, Edmonton and Commerce City). 

The
majority of Suncor's revenues from the sale of oil and natural gas commodities are based on prices that are determined by, or referenced to, U.S. dollar benchmark prices. The majority of
Suncor's expenditures are realized in Canadian dollars. An increase in the value of the Canadian dollar relative to the U.S. dollar will decrease revenue received from the sale of commodities.
A decrease in the value of the Canadian dollar relative to the U.S. dollar will increase the revenues received from the sale of commodities.

Conversely,
many of Suncor's assets and liabilities, notably most of the company's long-term debt, are denominated in U.S. dollars and translated to Suncor's reporting currency
(Canadian dollars) at each balance sheet date. An increase in the value of the Canadian dollar relative to the U.S. dollar from the previous balance sheet date decreases the Canadian dollars
required to settle U.S. dollar denominated obligations.

Oil Sands segment net and operating earnings for the first quarter of 2012 were $607 million, compared to $605 million of net earnings and
$694 million of operating earnings for the first quarter of 2011. In the first quarter of 2011, the company recorded an after-tax loss of $89 million on the partial
disposition of working interests in the Voyageur upgrader and Fort Hills mining projects. 

Oil
Sands operations contributed $538 million of operating earnings, while Oil Sands Ventures contributed $69 million. The decrease in operating earnings for Oil Sands operations,
compared to the first quarter of 2011, was due mainly to higher royalties and DD&A, and lower production associated with an unplanned Upgrader 2 outage, partially offset by higher average price
realizations. 

Cash
flow from operations for the Oil Sands segment in the first quarter of 2012 was $1.118 billion, compared to $1.137 billion in the first quarter of 2011, and decreased mainly due to
higher royalties and lower production volumes, partially offset by higher price realizations.

production from Oil Sands Base operations is upgraded, while bitumen production from In Situ operations is upgraded or sold directly to customers.
Yields of SCO and diesel from Suncor's upgrading process are approximately 79% of bitumen feedstock input. See also the Bitumen Production table presented below. 

Production volumes for Oil Sands operations averaged 305,700 bbls/d, compared to 322,100 bbls/d in the prior year quarter. Suncor achieved
consecutive monthly production records in January and February, averaging 355,000 bbls/d and 361,000 bbls/d, respectively, reflecting strong reliability from mining and extraction
operations and the ramp up of production from the Firebag Stage 3 expansion. In early March, as a result of an operational issue with a fractionator, the company took its Upgrader
2 facilities offline for unplanned maintenance. Upgrader 2 was successfully restarted in April. Production of upgraded product decreased compared to the prior year quarter, while
production of non-upgraded bitumen increased compared to the prior year quarter, primarily as a result of the Upgrader 2 outage.

Suncor's
share of Syncrude production and sales decreased to 35,400 bbls/d from 38,500 bbls/d in the prior year quarter. The decrease in production was due mainly to operational issues
with one of the coker units, which ran at reduced rates during the beginning of the quarter and was shut down in early March. The coker unit was returned to service in April.

Oil Sands Base bitumen production from mining and extraction activities associated with the Steepbank (including North Steepbank) and Millennium mining areas
averaged 262,500 bbls/d. Mining output was reduced for the duration of the Upgrader 2 outage. The company continues to mine through an area of lower bitumen ore grade quality at the
Millennium mine face, which the company expects to encounter through to the start of the fourth quarter of 2012. 

In
Situ bitumen production volumes averaged 114,600 bbls/d, increasing from 87,300 bbls/d in the prior year quarter. Average production from Firebag increased to 83,600 bbls/d
from 55,200 bbls/d in the prior year quarter. The ramp up of production from the Firebag Stage 3 expansion is proceeding in line with expectations. Bitumen production from Firebag has
also increased due to infill wells completed in 2011 and optimization of steam generation from Stage 3 facilities across the integrated Firebag complex. Higher
steam-to-oil ratios for Firebag reflect new wells coming on-stream and are also in line with expectations. The company anticipates that the Firebag steam-to-oil
ratio will decrease in future periods as the ramp up of production from the Stage 3 expansion continues. Average production from MacKay River decreased slightly to 31,000 bbls/d from
32,100 bbls/d in the prior year quarter.

Sales volumes for Oil Sands operations for the first quarter of 2012 reflected production levels from late 2011 and early 2012, averaging 332,800 bbls/d,
with the impacts of the Upgrader 2 outage expected to affect sales volumes mostly in the second quarter of 2012. 

The
sweet/sour sales mix for Oil Sands operations was 37% sweet in the first quarter of both 2012 and 2011. The impacts of higher bitumen sales that were a result of the Upgrader 2 outage were
largely offset by higher sales of sweet product that were a result of improved reliability in secondary upgrading facilities.

Average price realizations for sales from Oil Sands operations increased to $90.95/bbl (WTI less $12.12/bbl) in the first quarter of 2012 from $82.59
(WTI less $10.19/bbl) in the first quarter of 2011, due mainly to higher benchmark prices for crude oil. Average prices for sweet product from Oil Sands operations benefited from higher prices
for and production of diesel; however, prices for sweet SCO relative to WTI decreased significantly over the quarter, resulting in discounts for sweet SCO in the first quarter of 2012, compared with
premiums that were realized throughout much of 2011. 

 Royalties  

Royalties for the Oil Sands segment were higher in the first quarter of 2012 than in the same period in 2011. The increase was mainly
due to the prior year quarter including higher allowable costs for capital projects, primarily the TROTM infrastructure project. Royalties also increased because of higher prices for WTI
that influence the company's regulated bitumen valuation methodology, and higher In Situ bitumen production. These factors were partially offset by lower bitumen production from Oil Sands Base
and Syncrude. 

 Inventory  

Due to the outage at Upgrader 2 late in the first quarter of 2012, inventory levels decreased approximately 20%. The company
expects that it will rebuild inventory levels over the second quarter of 2012. The impact of drawing down inventory produced in previous periods was mostly offset by a decrease in inventory costs per
unit of production, whereby inventories produced in prior periods at relatively higher per unit costs were sold and replaced by inventories produced in the current period at relatively lower per
unit costs.

 Cash Operating Costs Reconciliation (1)(2) 

Cash
operating costs per barrel for Oil Sands operations increased in the first quarter of 2012, averaging $38.10/bbl compared to $35.45/bbl in the first quarter of 2011, impacted by lower production
(+$1.60/bbl) and higher total cash operating costs (+$1.05/bbl). 

Cash
operating costs for Oil Sands operations increased to $1.056 billion in the first quarter of 2012 from $1.028 billion in the first quarter of 2011. Total In Situ cash operating
costs were higher, due mainly to larger operations associated with the Firebag Stage 3 expansion and well workovers at MacKay River. Cash operating costs for Oil Sands Base were
consistent with the prior year quarter, as higher costs related to an increase in overburden removal activity were offset by lower energy costs, due primarily to lower natural gas prices, and
lower upgrading costs, due mainly to higher maintenance costs for secondary upgrading facilities in the prior year quarter.

operating costs and cash operating costs per barrel are non-GAAP financial measures. See the Non-GAAP Financial Measures
Advisory section of this MD&A.

	(2)
	Effective
with the first quarter of 2012, the calculation of cash operating costs has been revised to better reflect the ongoing cash costs of production,
and prior period figures have been re-determined. See the Non-GAAP Financial Measures Advisory section of this MD&A.

	(3)
	Significant
non-production costs include, but are not limited to, share-based compensation adjustments, costs related to the remobilization or
deferral of growth projects, research, the expense recorded as part of a non-monetary arrangement involving a third-party processor and feedstock costs for natural gas used to create
hydrogen for secondary upgrading processes.

	(4)
	Other
includes the impacts of changes in inventory valuation and a reduction for operating revenues associated with excess power from cogeneration units. 

 Expenses and Other Factors  

Operating expenses at Syncrude were lower in the first quarter of 2012 than in the first quarter of 2011, due primarily to lower
compensation expense and lower prices for natural gas. 

Other
Oil Sands operating expenses were lower in the first quarter of 2012, primarily due to lower project start-up costs and lower share-based compensation expense. The first quarter of
2011 included project start-up costs primarily related to the Firebag Stage 3 expansion, which was substantially complete by the first quarter of 2012. Project start-up
activity for the Firebag Stage 4 expansion is expected to increase in the second half of 2012. These decreases to other Oil Sands operating expenses were partially offset by higher costs
related to the deferral and subsequent remobilization of certain growth projects after the economic downturn in late 2008 and early 2009 ("safe mode" costs). Pre-tax safe mode costs were
$45 million in the first quarter of 2012, compared to $15 million in the first quarter of 2011, and increased due to activity pertaining to the Voyageur upgrader project. For 2012, the
company anticipates that safe mode costs will largely consist of the costs to assess the condition of assets coming out of safe mode and the costs of remobilizing equipment and personnel. 

DD&A
expense for the first quarter of 2012 was higher than in the same period of 2011, due mainly to a larger asset base that is the result of recently commissioned assets pertaining to the Firebag
Stage 3 expansion and costs capitalized as part of the major planned maintenance event in the second quarter of 2011. DD&A also increased due to charges related to the modifications of the MNU
hydrogen plant during the commissioning period.

The
factor presented in the bridge analysis of operating earnings for Financing Expense and Other Income was positive mainly due to a gain on the sale of a non-producing In Situ property
in the first quarter of 2012, partially offset by higher accretion expense for decommissioning and restoration provisions. 

 Planned Maintenance Events  

In the second quarter of 2012, the company expects to shut down one coker unit at Upgrader 1 for routine maintenance, which is not
anticipated to significantly impact production. In the third quarter of 2012, the company expects to complete routine maintenance on the vacuum tower and secondary upgrading units, and shut down one
coker unit at Upgrader 2. The impact of planned maintenance for the vacuum tower on overall production levels has been factored into Suncor's production forecasts. Planned maintenance for
secondary upgrading units at Upgrader 1 is now expected to occur in 2013. 

As
part of its regular annual maintenance program, Syncrude has scheduled a two-month outage for one of its other coker units for the second quarter of 2012.

Advisory section of this MD&A. 

Exploration and Production net earnings were $332 million in the first quarter of 2012, compared with a net loss of $186 million in the first
quarter of 2011. The net loss in the first quarter of 2011 included a $442 million deferred income tax expense adjustment related to an increase in U.K. statutory income tax rates and an
after-tax loss on the disposal of non-core assets of $81 million. 

Exploration
and Production operating earnings were $332 million in the first quarter of 2012, compared to $337 million in the first quarter of 2011. Operating earnings of
$164 million for East Coast Canada were higher due mainly to higher average price realizations. Operating earnings of $195 million for International were lower, reflecting lower overall
production volumes, partially offset by higher average price realizations. The operating loss of $27 million for North America Onshore was greater than in the prior year period, primarily due
to lower average price realizations for natural gas sales, lower production volumes and costs associated with a fire that broke out on a drilling rig in B.C.

Cash
flow from operations was $677 million for the first quarter of 2012, compared to $583 million for the first quarter of 2011, and increased primarily due to higher overall average
price realizations and the impact of current income tax on proceeds from the non-core asset dispositions in the prior year quarter.

	•
	Production from Terra Nova averaged 19,600 bbls/d and increased from 16,900 bbls/d in the prior year quarter.
In the first quarter of 2012, several production wells that were shut in due to the presence of hydrogen sulphide (H2S) in the prior year quarter were back on-stream following
the installation of a new subsea flow line in the fourth quarter of 2011. In addition, a new production well was completed in the third quarter of 2011. Terra Nova continues to be affected by partial
shut-ins of certain wells due to the presence of H2S, which the company expects to fully remediate during the planned maintenance event described below.  

	•
	Production from Hibernia averaged 28,700 bbls/d and decreased slightly from 29,200 bbls/d in the prior
year quarter.   

	•
	Production from White Rose averaged 17,000 bbls/d, and decreased from 18,900 bbls/d in the prior year
quarter, mainly as a result of natural declines, partially offset by new production from the pilot well in the West White Rose field of the White Rose Extensions. 

For
International, production averaged 96,200 boe/d in the first quarter of 2012, compared to 107,200 boe/d in the first quarter of 2011. 

	•
	Production from Libya averaged 39,200 bbls/d and increased from 24,100 bbls/d in the prior year quarter when
production was completely shut in beginning in March due to political unrest. Production has restarted in all major fields. Suncor is currently engaged in discussions with the National Oil Corporation
with respect to the impact of the force majeure period on the company's contractual obligations for its production and development activities. Suncor remains in force majeure for all exploration
activities.   

	•
	Production from Buzzard averaged 57,000 boe/d and increased from 50,300 boe/d, due mainly to higher
reliability than the prior year period.   

	•
	In December 2011, the company declared force majeure under its contractual obligations in Syria due to political
unrest and international sanctions affecting that country. As a result, the company recorded no production from Syria in the first quarter of 2012. In the first quarter of 2011, production from Syrian
assets averaged 17,400 boe/d.   

	•
	On March 31, 2011, the company completed its sale of non-core U.K. offshore assets. These
properties contributed 15,400 boe/d of production in the first quarter of 2011. 

For
North America Onshore, production averaged 358 mmcfe/d in the first quarter of 2012, compared to 411 mmcfe/d in the first quarter of 2011. 

	•
	During 2011, the company divested non-core assets that contributed incremental production of approximately
33 mmcfe/d in the prior year quarter.

	Production from remaining properties decreased primarily due to natural declines in reservoir performance and the shut in
of a small number of wells in response to low natural gas prices. The company continues to evaluate the possibility for further production shut-ins.

In the first quarter of 2012, price realizations for crude oil from East Coast Canada and International were higher than the first quarter of 2011, primarily due
to increasing benchmark prices for Brent crude. Price realizations for International were also higher due to the higher relative production mix of crude oil resulting from the suspension of operations
in Syria. Price realizations for North America Onshore were lower due mainly to lower benchmark prices for natural gas, partially offset by higher prices for natural gas liquids and crude oil. 

 Royalties  

Royalties for Exploration and Production were higher in the first quarter of 2012, compared with the same period in 2011, due
primarily to higher prices for crude oil production. Higher royalties related to the production increase from Libya were largely offset by lower royalties related to the suspension of operations
in Syria. 

 Expenses and Other Factors  

Operating expenses were lower in the first quarter of 2012 than in the first quarter of 2011, primarily due to the disposition of
non-core U.K. assets in 2011 and the suspension of operations in Syria, partially offset by expenses associated with the drilling rig fire. In March, while drilling a natural gas
well in B.C., a fire broke out on the rig. All workers were safely evacuated and the well has since been brought under control. An investigation is underway to determine the cause of
the incident. 

The
factor presented in the bridge analysis of operating earnings for Financing Expense and Other Income is negative, primarily due to the statutory income tax rate increase in the U.K.

   Planned Maintenance Events  

The estimated 21-week dockside maintenance program for the Terra Nova Floating Production Storage and Offloading (FPSO)
vessel is scheduled to begin in June 2012. The planned work includes the replacement of the FPSO water injection swivel and the completion of the replacement of subsea infrastructure to
remediate H2S issues. The estimated 18-week off-station maintenance program for the White Rose FPSO is scheduled to commence in May 2012, primarily to
address issues with the FPSO propulsion system. During these outages, there will be no production from the respective assets. Planned maintenance events are scheduled to occur at Hibernia and Buzzard
in the third quarter of 2012.

	The
company has reclassified the prior year operating earnings split between Refining and Product Supply and Marketing to conform to the current year
presentation. Total operating earnings are unchanged. 

Refining and Marketing had net and operating earnings of $474 million in the first quarter of 2012, compared with net and operating earnings of
$627 million in the first quarter of 2011. 

Refining
and Product Supply activities contributed $396 million to operating earnings in the first quarter of 2012, which was lower than in the same period in the prior year. In the first
quarter of 2011, the uplift to operating earnings with respect to the impact of a rising crude price environment on Suncor's refining margins was approximately $185 million after tax, compared
with an uplift of approximately $7 million after tax for the first quarter of 2012. In addition, reduced demand for refined product in Eastern North America resulted in lower crude throughputs
at the Montreal and Sarnia refineries. Marketing activities contributed $78 million to operating earnings in the first quarter of 2012, which was higher than in the same period in the prior
year, due mainly to stronger margins in wholesale and lubricants channels, partially offset by lower overall sales volumes and margins in retail channels. 

Refining
and Marketing cash flow from operations was $741 million in the first quarter of 2012, compared to $929 million in the first quarter of 2011, and decreased primarily due to the
same factors that affected operating earnings.

Total sales of refined petroleum products averaged 80,100 m3/d in the first quarter of 2012, compared to 82,000 m3/d in
the first quarter of 2011. Gasoline and distillate sales in Eastern North America decreased 9% and 16%, respectively,

primarily
reflecting lower demand for gasoline resulting from higher prices and lower demand for distillate reflecting higher prices and warmer weather conditions. These decreases were partially
offset by higher sales volumes in Western North America. 

Crude
oil processed for Eastern North America averaged 30,300 m3/d and decreased from 33,100 m3/d in the prior year quarter. This decrease was concurrent with
the decrease in demand for refined products, and was also due to an outage for one of the crude distillation towers at the Sarnia refinery, which was restarted successfully in April. Crude oil
processed for Western North America averaged 36,400 m3/d and increased from 35,300 m3/d in the prior year quarter, primarily due to better reliability and
scheduled maintenance events at the Commerce City refinery in the first quarter of 2011. 

 Prices and Margins  

Prices for refined products were higher in the first quarter of 2012 than in the first quarter of 2011, reflecting higher refining
crack spreads. 

For
Refining and Product Supply, although WTI prices increased significantly during the first quarters of 2012 and 2011, the impact on earnings pertaining to the increasing crude price environment
that benefited the first quarter of 2011 (approximately $185 million after tax) was not repeated in the first quarter of 2012 (approximately $7 million after tax). This effect was the
result of a smaller increase in the price of WTI in the first quarter of 2012, compared to the first quarter of 2011, and widening price discounts relative to WTI near the end of the first quarter of
2012 for much of the crude feedstock that the company's inland refineries (Sarnia, Edmonton and Commerce City) process. 

For
Marketing, higher margins in wholesale channels and higher margins for lubricants products were partially offset by lower margins from the retail channel. 

 Expenses and Other Factors  

Operating expenses were lower in the first quarter of 2012 than in the first quarter of 2011, due primarily to lower share-based
compensation expense, partially offset by higher costs for remediation and maintenance. The factor presented in the bridge analysis of operating earnings for Financing Expense and Other Income was
negative primarily due to a gain pertaining to the company's investments in marketing entities recorded in the first quarter of 2011.

Net earnings for Corporate, Energy Trading and Eliminations in the first quarter of 2012 were $44 million, compared with a net loss of $18 million
in the first quarter of 2011. In the first quarter of 2012, the Canadian dollar strengthened in relation to the U.S. dollar, with the US$/Cdn$ exchange rate increasing from 0.98 to 1.00 and
resulting in an after-tax unrealized foreign exchange gain on U.S. dollar denominated long-term debt of $128 million. In the first quarter of 2011, the Canadian
dollar strengthened in relation to the U.S. dollar as the exchange rate increased from 1.01 to 1.03, resulting in an after-tax unrealized foreign exchange gain on U.S. dollar
denominated long-term debt of $162 million. 

 Operating Earnings  

The operating loss for Corporate, Energy Trading and Eliminations in the first quarter of 2012 was $84 million, compared with
an operating loss of $180 million in the first quarter of 2011.

Renewable Energy operating earnings of $15 million in the first quarter of 2012 were consistent with operating earnings from the first quarter of 2011.
The impacts of higher ethanol production volumes were largely offset by the timing of and contractual limits for government ethanol incentive funding. At the end of January 2011, Suncor
completed the expansion of its ethanol plant in Ontario, which increased nameplate production capacity from 200 million litres per year to 400 million litres per year. Total power
generation marketed increased to 141 gigawatt hours from 55 gigawatt hours, due mainly to two new wind power projects that commenced operations in 2011 (Wintering Hills in southern
Alberta and Kent Breeze in southwest Ontario). 

 Energy Trading  

Energy Trading operating earnings increased to $52 million from $39 million in the prior year quarter, with the increase
occurring primarily in heavy crude trading strategies, whereby heavy crude oil is purchased in Alberta and delivered to markets with more favourable prices. 

 Corporate  

The Corporate operating loss was $133 million in the first quarter of 2012, compared with an operating loss of
$189 million in the first quarter of 2011. The company capitalized 98% of its borrowing costs in the first quarter of 2012

as
part of the cost of major development assets and construction projects, compared to 62% in the prior year quarter. In addition, lower share-based compensation expense was partially offset by higher
DD&A expense that reflected the start of depreciation on Suncor's post-merger systems integration initiative. 

 Group Eliminations  

Group Eliminations include the elimination of profit on crude oil sales from Oil Sands and East Coast Canada to Refining and Product
Supply. Consolidated profits are only realized when the company determines that the refined products produced from internal purchases of crude feedstock have been sold to third parties. During the
first quarter of 2012, the company eliminated $18 million of after-tax intersegment profit.

 Oil Sands Base  

Oil Sands Base capital and exploration expenditures were $434 million, of which $409 million was directed towards
sustaining activities. Sustaining capital expenditures related primarily to the company's TROTM initiative, and included $241 million towards the infrastructure project to construct
pumping and pipeline facilities for tailings and
water transfers across mining operations, and the construction of tailings drying facilities. The company has started commissioning TROTM infrastructure assets and expects to start
utilizing these assets in the second quarter of 2012. Other sustaining capital expenditures focused on initiatives at Upgrader 1 and Upgrader 2 facilities. 

Spending
on growth capital projects for Oil Sands Base in the first quarter of 2012 was limited to the completion of assets supporting the North Steepbank mining extension and modifications to the
hydrogen plant portion of the MNU, which was taken offline for modifications in the first quarter of 2012. The company expects that the MNU project will be fully operational
by mid-year. 

 In Situ  

In Situ capital and exploration expenditures were $474 million, of which $295 million was directed towards growth
projects.  

	•
	Capital expenditures for the Firebag Stage 4 expansion were $156 million, bringing total project expenditures
to date to approximately $1.344 billion. Construction activities continued to focus on the two new well pads, central processing facilities and cogeneration units. Initial production is
targeted for the first quarter of 2013.   

	•
	Capital expenditures for the Firebag Stage 3 expansion were $11 million. Growth spending for Stage 3
is essentially complete, with remaining activities related only to infrastructure projects also required for the Stage 4 expansion. Total Stage 3 project expenditures to date are
approximately $4.381 billion. 

In
Situ sustaining capital expenditures of $179 million were directed primarily to the design and engineering of new well pads that will support existing production levels from MacKay River and
Firebag Stages 1 and 2 in future years. 

 Oil Sands Ventures  

Suncor's share of capital expenditures for the Syncrude joint venture was $40 million, which included $17 million for
mine train replacement at the Mildred Lake mine and the equipment relocation at the Aurora mine. 

During
the first quarter of 2012, Oil Sands Ventures growth capital expenditures were $79 million, with (i) the Voyageur upgrader project focusing on validating project scope, developing
the project execution plan, engineering and progressing site preparation; (ii) the Fort Hills mining project focusing on progressing design basis memorandum engineering and site preparation,
and procuring long-lead items; and (iii) the Joslyn North mining project (operated by Total E&P) focusing on further design work, drilling and site preparation. In 2013, the
company expects to present the development plans for all three projects to Suncor's Board of Directors for sanctioning. The development of each of these projects remains subject to approval by the
joint venture owners of the respective projects. 

 Other Capital and Exploration Expenditures  

In the first quarter of 2012, the Exploration and Production segment spent $204 million on capital and exploration
expenditures. Growth spending included $50 million for Golden Eagle that focused on detailed engineering and the start of construction of topsides and platform jackets. Other growth capital
included drilling in the Cardium oil and Montney shale gas formations, and engineering and construction site preparation for the Hebron project. In April, the company commenced drilling the second
appraisal well for the Beta discovery in the Norway portion of the North Sea.

 Capital Resources  

Suncor's management believes the company will have the capital resources to fund its planned 2012 capital spending program and meet
current and long-term working capital requirements through existing cash balances and short-term investments, cash flow from operations for the remainder of 2012, and available
committed credit facilities. The company's cash flow from operations depends on a number of factors, including commodity prices, production and sales volumes, refining and marketing margins, operating
expenses, taxes, royalties and foreign exchange rates. If additional capital is required, Suncor's management believes adequate additional financing will be available in debt capital markets at
commercial terms and rates. 

Due
primarily to strong cash flow from operations that exceeded capital expenditures, cash and cash equivalents increased $845 million during the first quarter of 2012, including the effects of
returning $183 million to shareholders as part of the share repurchase program. For the twelve months ended March 31, 2012, the company's net debt to cash flow from operations measure
was 0.6 times, which met management's target of less than 2.0 times. Unutilized lines of credit at March 31, 2012 were $4.694 billion, compared to $4.428 billion at
December 31, 2011. 

 Financing Activities  

Management of debt levels continues to be a priority for Suncor given the company's long-term growth plans. Suncor's
management believes a phased and flexible approach to existing and future growth projects should assist Suncor in maintaining its ability to manage project costs and debt levels. 

At
March 31, 2012, Suncor's net debt was $5.966 billion, compared to $6.976 billion at December 31, 2011. Over the first three months of 2012, net debt decreased by
$1.010 billion, largely due to cash flow from operations that exceeded capital and exploration expenditures. 

The
company expects to maintain access to short-term commercial paper borrowing at competitive interest rates by keeping short-term debt at existing levels (approximately
$750 million). During 2011, the company transitioned the majority of its short-term debt to U.S. dollar denominated commercial paper. The company has invested excess cash in
short-term financial instruments that are presented as cash and cash equivalents. The objectives of the company's short-term investment portfolio are to ensure the preservation
of capital, maintain adequate liquidity to meet Suncor's cash flow requirements and deliver competitive returns consistent with the quality and diversification of investments within

acceptable
risk parameters. The maximum weighted average term to maturity of the short-term investment portfolio will not exceed six months, and all investments will be with counterparties
with investment grade debt ratings. As at March 31, 2012, the weighted average term to maturity of the short-term investment portfolio was approximately 55 days. 

During
the first quarter of 2012, the company obtained regulatory approval to recommence its Normal Course Issuer Bid (NCIB) with the Toronto Stock Exchange that authorizes the purchase for
cancellation of up to an additional $1.0 billion of Suncor's common shares between February 28, 2012 and September 5, 2012. Pursuant to the NCIB, during this time, Suncor will not
purchase more than 45,839,791 common shares. The actual number of common shares that will be repurchased under the NCIB, and the timing of any such purchases, will be determined by the company.
The company subsequently announced that it had entered into a pre-defined purchase plan with a designated broker to allow for the repurchase of common shares during scheduled and
unscheduled share trading blackout periods. Shareholders may obtain a copy of the company's Notice of Intention to make a Normal Course Issuer Bid by contacting Investor Relations. 

During
the first quarter of 2012, the company repurchased 5,466,200 shares at an average price of $33.46 per share, for a total repurchase cost of $183 million. All common shares
acquired under the NCIB will be cancelled. As of April 27, 2012, the company had repurchased an additional 4,332,400 shares at an average price of $30.91 per share ($134 million). The
company does not expect the decision to allocate cash to the NCIB will affect its long-term growth strategy. 

Suncor
is subject to financial and operating covenants related to its public market and bank debt. Failure to meet the terms of one or more of these covenants may constitute an Event of Default as
defined in the respective debt agreements, potentially resulting in accelerated repayment of one or more of the debt obligations. The company is in compliance with its financial covenant that requires
total debt to not exceed 60% of its total debt plus shareholders' equity. At March 31, 2012, total debt to total debt plus shareholders' equity was 21% (December 31,
2011 – 22%). The company is also currently in compliance with all operating covenants.

 Contractual Obligations, Commitments, Guarantees, and Off-Balance Sheet Arrangements  

In the normal course of business, the company is obligated to make future payments, including contractual obligations and
non-cancellable commitments. Suncor has included these items in the Financial Conditions and Liquidity section of its 2011 annual MD&A, which section is herein incorporated by reference.
Since December 31, 2011, there have been no material changes to amounts presented in the Contractual Obligations, Commitments, Guarantees, and Off-Balance Sheet Arrangements table.
The company does not believe that it has any guarantees or off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on the company's
financial condition, results of operations, liquidity or capital expenditures.

   Ontario Provincial Budget Proposal  

The Province of Ontario budget was presented on March 27, 2012, and proposes to freeze the general corporate income tax rate at
11.5%, instead of the planned reduction to 10% by 2014. The company's preliminary assessment is that, if passed, the budget will result in deferred income tax expense of approximately
$65 million to revalue the company's deferred income tax balances.

Trends in Suncor's quarterly earnings results and cash flow from operations are driven primarily by production volumes, which can be significantly impacted by
major planned maintenance events, such as the one that occurred at Upgrader 2 in Oil Sands in the second quarter of 2011, and unplanned maintenance outages, such as the one that occurred at
Upgrader 2 in the first quarter of 2012, and by changes in commodity prices, refining crack spreads and foreign exchange rates.

 Significant or Unusual Items Impacting Net Earnings  

Net earnings over the last eight quarters were affected by the following events or one-time
adjustments: 

	•
	The second quarter of 2011 included impairment charges of $514 million against assets in Libya that were associated
with the shut in of production due to political unrest, which also decreased production volumes for the majority of 2011.   

	•
	The first quarter of 2011 included a $442 million adjustment to deferred income tax expense related to an increase
in U.K. tax rates on oil and gas profits in the North Sea.   

	•
	As part of its strategic business alignment subsequent to the merger with Petro-Canada, Suncor divested a number of
non-core assets in its Exploration and Production segment throughout 2010 and 2011. Decreases in production volumes in 2011 are due in part to the disposition of these assets. The
resulting gains and losses on the disposition of these assets had one-time impacts on net earnings in the quarters in which they occurred.   

	•
	The fourth quarter of 2010 included an after-tax gain of $186 million for the redetermination of working
interests in the Terra Nova oilfield and an after-tax royalty recovery of $93 million with respect to the modification of the bitumen valuation methodology calculation.  

	•
	The second quarter of 2010 included an after-tax write-off of $141 million for Oil Sands
assets that were being used in the development of an alternative extraction process.

 9. OTHER ITEMS  

 Accounting Policies  

Suncor's significant accounting policies and a summary of recently announced accounting standards are described in notes 3
and 5, respectively, to the audited Consolidated Financial Statements for the year ended December 31, 2011, which notes are herein incorporated by reference. 

During
the first quarter of 2012, the company completed a review of the presentation of purchase and sale transactions in its Oil Sands segment, and determined that certain transactions previously
recorded on a gross basis are more appropriately reflected through net presentation. These transactions represent volumes exchanged with third parties in corresponding sales and purchase agreements,
typically when Oil Sands Base or third-party refinery capacities are constrained. Netted sales transactions do not include any Suncor production volumes. Prior period figures have been reclassified
for comparability with the current period presentation. The impact of these reclassifications, which did not affect earnings, is as follows:

 Critical Accounting Estimates  

The preparation of financial statements in accordance with GAAP requires management to make estimates, judgments and assumptions that
affect reported assets, liabilities, revenues and expenses, gains and losses, and disclosures of contingencies. These estimates and assumptions are subject to change based on experience and new
information. Critical accounting estimates are those that require management to make assumptions about matters that are highly uncertain at the time the estimate is made. Critical accounting estimates
are also those estimates, which, where a different estimate could have been used or where changes in the estimate that are reasonably likely to occur, would have a material impact on the company's
financial condition, changes in financial condition or financial performance. Critical accounting estimates are reviewed annually by the Audit Committee of the Board of Directors. A detailed
description of Suncor's critical accounting estimates is provided in the Accounting Policies and Critical Accounting Estimates section of Suncor's 2011 annual MD&A, which section is herein

Suncor periodically enters into derivative contracts such as forwards, futures, swaps, options and costless collars to manage exposure
to fluctuations in commodity prices and foreign exchange rates, and to optimize the company's position with respect to interest payments. The company also uses physical and financial energy
derivatives to earn trading profits. For more information on Suncor's financial instruments and the related financial risk factors, see note 28 of the audited Consolidated Financial Statements
for the year ended December 31, 2011, which note is herein incorporated by reference. 

 Control Environment  

Based on their evaluation as of March 31, 2012, Suncor's Chief Executive Officer and Chief Financial Officer concluded that the
company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the United States Securities Exchange Act of 1934
(the Exchange Act)) are effective to ensure that information required to be disclosed by the company in reports that are filed or submitted to Canadian and U.S. securities authorities is
recorded,

processed,
summarized and reported within the time periods specified in Canadian and U.S. securities laws. In addition, as of March 31, 2012, there were no changes in the internal
control over financial reporting (as defined in Exchange Act Rules 13a-15(f) – 15d-15(f)) that occurred during the
three-month period ended March 31, 2012 that have materially affected, or are reasonably likely to materially affect, the company's internal control over financial reporting. Management will
continue to periodically evaluate the company's disclosure controls and procedures and internal control over financial reporting and will make any modifications from time to time as deemed necessary. 

As
a result of past unrest in Libya and current events in Syria, Suncor is not able to monitor the status of all of its facilities, including whether certain facilities have suffered damages. Suncor
has assessed and is continually monitoring the control environment in these countries and does not consider the changes to have a material impact on the company's overall internal control over
financial reporting. 

Based
on their inherent limitations, disclosure controls and procedures and internal control over financial reporting may not prevent or detect misstatements, and even those controls determined to be
effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 

 Corporate Guidance  

Suncor has updated its 2012 corporate guidance that was previously issued on February 1, 2012. The press release of Suncor
dated April 30, 2012, which is also available on www.sedar.com, provides the new guidance and the reasons for the revisions. 

 10. NON-GAAP FINANCIAL MEASURES ADVISORY  

Certain financial measures in this MD&A – namely operating earnings, ROCE, cash flow from operations and Oil
Sands cash operating costs – are not prescribed by GAAP. These non-GAAP financial measures do not have any standardized meaning and therefore are
unlikely to be comparable to similar measures presented by other companies. These non-GAAP financial measures are included because management uses the information to analyze operating
performance, leverage and liquidity. Therefore, these non-GAAP financial measures should not be considered in isolation or as a substitute for measures of performance prepared in
accordance with GAAP. Except as otherwise indicated, these non-GAAP measures are calculated and disclosed on a consistent basis from period to period. Specific adjusting items may only be
relevant in certain periods. 

 Operating Earnings  

Operating earnings is a non-GAAP financial measure that adjusts net earnings for significant items that are not indicative
of operating performance. Management uses operating earnings to evaluate operating performance, because management believes it provides better comparability between periods.

   Return on Capital Employed (ROCE)  

ROCE is a non-GAAP financial measure that management uses to analyze operating performance and the efficiency of Suncor's
capital allocation process. Average capital employed is calculated as a thirteen-month average of the capital employed balance at the beginning of the twelve-month period and the month-end
capital employed balances throughout the remainder of the twelve-month period. Figures for capital employed at the beginning and end of the twelve-month period are presented to show the changes in the
components of the calculation over the twelve-month period.

 Cash Flow from Operations  

Cash flow from operations is a non-GAAP financial measure that adjusts a GAAP
measure – cash flow provided by operating activities – for changes in non-cash working capital, which management
uses to analyze operating performance and liquidity. Changes to non-cash working capital can include, among other factors, fluctuations for the timing or payment of share-based
compensation amounts, offshore feedstock purchases, and fuel and income taxes, which management believes reduces comparability between periods.

 Oil Sands Cash Operating Costs  

Oil Sands cash operating costs and cash operating costs per barrel are non-GAAP financial measures, which are derived by
adjusting Oil Sands segment operating, selling and general expense (a GAAP measure based on sales volumes) for (i) costs pertaining to Syncrude operations;
(ii) non-production costs that management believes do not relate to the production performance of Oil Sands operations including, but not limited to, share-based compensation
adjustments, costs related to the remobilization or deferral of growth projects, research, the expense recorded as part of a non-monetary arrangement

involving
a third-party processor and feedstock costs for natural gas used to create hydrogen for secondary upgrading processes; (iii) excess power generated and sold that is recorded in
operating revenue; and (iv) the impacts of changes in inventory levels, such that the company is able to present cost information based on production volumes. Oil Sands cash operating costs are
reconciled in the Segmented Results and Analysis – Oil Sands section of this MD&A. 

Effective
2012, the calculation of Oil Sands cash operating costs has been updated to better reflect the ongoing cash cost of production, and prior period figures have been re-determined.
The cost of natural gas feedstock for secondary upgrading processes, the cost of diluent purchased for transportation of product to markets, and non-cash costs related to the accretion of
liabilities for decommissioning and restoration provisions are no longer included in cash operating costs. Certain cash costs relating to safety programs, which were previously considered
non-production costs, are now included in cash operating costs. The following table reconciles amounts previously reported to those presented in this MD&A:

spending program and to meet current and long-term working capital requirements through existing cash balances and short-term investments, cash flow from operations for the remainder
of 2012, and available committed credit facilities, and that if additional capital is required, adequate additional financing will be available to Suncor in the debt capital markets at
commercial terms and rates;

	•
	Management's belief that a phased and flexible approach to existing and future growth projects
should assist Suncor in maintaining its ability to manage project costs and debt levels;

	•
	The company's belief that it does not have any guarantees or off-balance sheet arrangements that are
reasonably likely to have a future material impact on the company's financial condition, results of operations, liquidity or capital expenditures;

	•
	The company's plans to maintain short-term commercial paper borrowing at competitive
interest rates by keeping short-term debt at existing levels;

	•
	The company's expectation that the decision to allocate cash to the NCIB will not affect its
long-term growth strategy; and

	•
	The company's expectations that the maximum weighted average term to maturity of its

Forward-looking statements and information are not guarantees of future performance and involve a number of risks and uncertainties, some that are similar to other oil and gas
companies and some that are unique to Suncor. Suncor's actual results may differ materially from those expressed or implied by its forward-looking statements, so readers are cautioned not to place
undue reliance on them.

The financial and operating performance of the company's reportable operating segments, specifically Oil Sands, Exploration and Production, and Refining and Marketing, may be
affected by a number of factors.

Factors that affect our Oil Sands segment include, but are not limited to, volatility in the prices for crude oil and other production, and the related impacts of fluctuating
light/heavy and sweet/sour crude oil differentials; changes in the demand for refinery feedstock and diesel fuel, including the possibility that refiners that process our proprietary production will
be closed, experience equipment failure or other accidents; our ability to operate our oil sands facilities reliably in order to meet production targets; the output of newly commissioned facilities,
the performance of which may be difficult to predict during initial operations; the possibility that completed maintenance activities may not improve operational performance or the output of related
facilities; our dependence on pipeline capacity and other logistical constraints, which may affect our ability to distribute our products to market; our ability to finance oil sands growth and
sustaining capital expenditures; the availability of bitumen feedstock for upgrading operations, which can be negatively affected by poor ore grade quality, unplanned mine equipment and extraction
plant maintenance, tailings storage, and in situ reservoir and equipment performance, or the unavailability of third-party bitumen; inflationary pressures on operating costs, including labour, natural
gas and other energy sources in oil sands processes; our ability

 to complete projects, including planned maintenance events, both on time and on budget, which could be impacted by competition from other projects (including other oil sands projects) for goods and
services and demands on infrastructure in Fort McMurray and the surrounding area (including housing, roads and schools); risks and uncertainties associated with obtaining regulatory and
stakeholder approval for exploration and development activities; changes to royalty and tax legislation and related agreements that could impact our business, such as our current dispute with the
Alberta Department of Energy in respect of the Bitumen Valuation Methodology Regulation; the potential for disruptions to operations and construction projects as a result of our relationships with
labour unions that represent employees at our facilities; and changes to environmental regulations or legislation.

Factors that affect our Exploration and Production segment include, but are not limited to, volatility in crude oil and natural gas prices; operational risks and uncertainties
associated with oil and gas activities, including unexpected formations or pressures, premature declines of reservoirs, fires, blow-outs, equipment failures and other accidents,
uncontrollable flows of crude oil, natural gas or well fluids, and pollution and other environmental risks; the possibility that completed maintenance activities may not improve operational
performance or the output of related facilities; adverse weather conditions, which could disrupt output from producing assets or impact drilling programs, resulting in increased costs and/or delays in
bringing on new production; political, economic and socio-economic risks associated with Suncor's foreign operations, including the unpredictability of operating in Libya and that operations in Syria
continue to be impacted by sanctions or political unrest; risks and uncertainties associated with obtaining regulatory and stakeholder approval for exploration and development activities; the
potential for disruptions to operations and construction projects as a result of our relationships with labour unions that represent employees at our facilities; and market demand for mineral rights
and producing properties, potentially leading to losses on disposition or increased property acquisition costs.

Factors that affect our Refining and Marketing segment include, but are not limited to, fluctuations in demand and supply for refined products that impact the company's margins;
market competition, including potential new market entrants; our ability to reliably operate refining and marketing facilities in order to meet production or sales targets; the possibility that
completed maintenance activities may not improve operational performance or the output of related facilities; risks and uncertainties affecting construction or planned maintenance schedules, including
the availability of labour and other impacts of competing projects drawing on the same resources during the same time period; and the potential for disruptions to operations and construction projects
as a result of our relationships with labour unions or employee associations that represent employees at our refineries and distribution facilities.

Additional risks, uncertainties and other factors that could influence financial and operating performance of all of Suncor's operating segments and activities include, but are
not limited to, changes in general economic, market and business conditions, such as commodity prices, interest rates and currency exchange rates; fluctuations in supply and demand for Suncor's
products; the successful and timely implementation of capital projects, including growth projects and regulatory projects; competitive actions of other companies, including increased competition from
other oil and gas companies or from companies that provide alternative sources of energy; labour and material shortages; actions by government authorities, including the imposition of taxes or changes
to fees and royalties, and changes in environmental and other regulations; the ability and willingness of parties with whom we have material relationships to perform their obligations to us; the
occurrence of unexpected events such as fires, equipment failures and other similar events affecting Suncor or other parties whose operations or assets directly or indirectly affect Suncor; the
potential for security breaches of Suncor's information systems by computer hackers or cyberterrorists, and the unavailability or failure of such systems to perform as anticipated as a result of such
breaches; our ability to find new oil and gas reserves that can be developed economically; the accuracy of Suncor's reserves, resources and future production estimates; market instability affecting
Suncor's ability to borrow in the capital debt markets at acceptable rates; maintaining an optimal debt to cash flow ratio; the success of the company's risk management activities using derivatives
and other financial instruments; the cost of compliance with current and future environmental laws; risks and uncertainties associated with closing a transaction for the purchase or sale of an oil and
gas property, including estimates of the final consideration to be paid or received, the ability of counterparties to comply with their obligations in a timely manner and the receipt of any required
regulatory or other third-party approvals outside of Suncor's control that are customary to transactions of this nature; and the accuracy of cost estimates, some of which are provided at the
