Letter to 
shareholders

T. J. (Tim) Hearn
Chairman, president and chief executive officer

2003 was another very good year for Imperial and its shareholders. Earnings
reached a new record of $1,682 million, or $4.52 per share. Return on average
capital employed of 24 percent and return on shareholders’ equity of 31 percent
were among the highest in history. The company’s safety performance was the
best on record, and operations were conducted in a continuously improving
and environmentally responsible manner.

Imperial continued to provide excellent
value to shareholders. Regular per-share
dividends were increased for the ninth
consecutive year, and shareholders
continued to benefit from the ongoing
share buyback program. The company
maintained its strong financial position,
while making solid progress on major
projects aimed at ensuring long-term
growth in shareholder value. For the
second year in succession, capital and
exploration expenditures exceeded
$1.5 billion. 

The major factors behind Imperial’s
financial performance in 2003 were
higher crude oil and natural gas prices
and relatively strong industry margins
for petroleum products. However,
commodity prices are volatile and

heavily influenced by a variety of
factors, including supply, demand, and
political and other events. For this
reason, Imperial remains committed to
its long-standing strategy of focusing
on the factors we can control in the
business, as reflected in our four
corporate priorities. This allows us to
weather difficult times and to prosper
when market conditions are favourable.

We also continued to lay a foundation
for future profitability by investing
in attractive long-term growth
opportunities. Major projects in natural
resources included advancing the
expansion at Syncrude, further
increasing production at Cold Lake,
progressing the planned project to
develop natural gas resources in the

Mackenzie Delta, advancing plans to
develop the Kearl oil-sands properties
near Fort McMurray, Alberta, and
pursuing promising exploration
opportunities off Canada’s East Coast.

In petroleum products, major upgrades
were completed at our refineries that
reduced the sulphur content of the
company’s gasolines to 30 parts per
million – more than a year ahead
of the regulatory requirements.
Construction also progressed on a
cogeneration facility at the Sarnia
manufacturing complex.

I continue to be encouraged by
the prospects for long-term earnings
growth driven by the continued need
for and growth of petroleum energy.

Annual report 2003

Imperial remains focused on our four corporate priorities:
flawless execution, growth in profitable sales, best-in-class
costs and improved productivity of our asset mix.

There is a long-standing, proven
correlation between population and
economic growth and energy use.
Growing economies will continue to
require reliable and affordable supplies
of all forms of energy. Events in 2003,
such as the major power outage in
Ontario and the northeastern United
States, brought home the importance
of reliable, affordable supplies of
energy and the inextricable link
between energy use and our way 
of life. 

Most informed forecasters agree that
oil and natural gas will supply a major
proportion of this growing demand 
and will remain the dominant sources
of the world’s energy for at least the
next several decades. No other source
of energy provides a competitive
combination of availability, affordability,
efficient infrastructure and relative
ease of safe handling and storage.
In addition, petroleum provides the
feedstock for literally thousands of
products that are critical to our daily
lives and economic activity.

To meet this projected need for
petroleum energy, major new supply
development will be required globally.
In fact, about half of the oil and gas
that will be needed 10 years from 
now will have to come from fields
not currently in production.

Canada and Canada’s petroleum
industry are uniquely well positioned
to become an even more significant
producer and exporter than we are
today, realizing the full value of our
abundant energy resources. We have
the natural resources, the expertise
and experience to develop them, and
close access, along with established
infrastructures for transportation of oil
and gas, to the world’s largest energy
market in the United States. We also
offer a degree of political stability and
reliability that can attract the major
investments needed to develop our
resources on the scale required.

Imperial, with access to a resource
base of about 11 billion gross oil-
equivalent barrels from diverse
sources and a significant position in
Canada’s major opportunity areas, 
is well positioned to be a major
participant in this growth. 

We have the financial strength, well-
delineated and proven strategies, a
disciplined management approach, and
highly capable, dedicated employees
who continue to demonstrate their
commitment to excellence. 

Our capabilities are further leveraged
by funding and participating in new
and evolving technologies through
ExxonMobil’s worldwide research and
development programs. We remain
committed to the highest standards
of corporate governance, ethics and
integrity in all aspects of our business.

With these strengths and our proven
record of performance, I believe
shareholders can look forward to a
future of long-term earnings growth
for Imperial.

The year in review

Strong commodity prices and industry margins for petroleum
products contributed to record earnings of $1,682 million, or
$4.52 a share, in 2003. The company’s capital and exploration
expenditures of more than $1.5 billion were more than double
the average during the 1990s and more than twice the current
rate of depreciation and depletion.

All major business units under Imperial’s direct control had
operating costs in the first quartile of the competitive range, and
several were at best-in-class levels. Imperial has a long-term
goal of having all its major businesses operating at best-in-class
cost levels and employs rigorous external benchmarking
processes to monitor performance.

In 2003, research expenditures in Canada were $36 million. In
addition, Imperial participates in and has access to worldwide
research of about $1 billion a year carried out by Exxon Mobil
Corporation.

Imperial’s financial strength enables it to pursue attractive
opportunities relatively independent of short-term market
conditions. The balance sheet has remained strong over time,
with a debt-to-capital ratio consistently in the 20–30 percent
range. The company’s ability to meet its debt obligations was
strengthened. In 2003, interest coverage on an earnings basis
was more than 63 times, and on a cash-flow basis more than
79 times. This financial strength helped Imperial sustain the only
Canadian industrial Triple-A rating from Standard & Poor’s.

In 2003, an independent actuarial review of the company’s
registered pension plan showed the deficit to be in line with
the company’s expectations based on the downturn in equity
markets since the last review in 2000. Imperial funded more
than $500 million of this deficit in 2003 and expects that it
can meet any further funding requirements without affecting
current or future investment plans.

Natural
resources

For Imperial’s natural resources business, 2003 was an
excellent year. Earnings after tax were $1,139 million, a
near record, and return on average capital employed was 
32 percent. Operations generated more than $1.5 billion
cash flow from earnings, of which $1 billion was reinvested
in capital and exploration. Strong operating performance
yielded overall production for the year of 342,000 
oil-equivalent barrels a day before royalties. Significant
progress was made on projects aimed at ensuring future
growth in production and earnings.

Oil-sands resources at Cold Lake (above) and Kearl
(below and next page) contribute to Imperial’s strong

Oil-sands operations

Imperial’s Cold Lake operation is a premier oil-sands resource
for the company and for Canada – the largest thermal heavy-oil
operation in the Western Hemisphere and the second largest in
the world. In 2003, bitumen production was 129,000 barrels a
day before royalties, an increase of 15 percent over 2002. 

Phased development of Cold Lake has been a deliberate and
successful strategy. New production has been brought on
as markets have developed, and the company has been able 
to make use of the most advanced technologies available.

Proved reserves of crude oil and natural gas (a)

The most recent expansion, phases 11–13, was successfully
commissioned in late 2002 and achieved a production rate 
of more than 30,000 barrels a day in early cycles. The expansion
included a 170-megawatt, natural-gas-fired cogeneration facility
that has improved energy efficiency and now supplies all the
electric power needed for the entire Cold Lake operation. The
expansion was recently named “project of the year” for 2003 
by Alberta Construction magazine.

Natural resources (continued)

Oil-sands operations (continued)

In 2004, a significant development drilling program of more than
300 wells is planned within the currently approved development
area to enhance productivity from existing Cold Lake phases.
Opportunities are also being evaluated to improve utilization
of the existing infrastructure. Regulatory approval for further
expansion of the Cold Lake development area is anticipated 
this year. Expansions and future phases will continue to be
advanced as market conditions allow. 

Production from Imperial’s 25-percent share in Syncrude
operations was 53,000 barrels of synthetic crude oil a day
before royalties, down from 57,000 barrels a day in 2002,
mainly due to unplanned maintenance and equipment
reliability issues. Syncrude management has developed plans
to address these in 2004.

Construction continued on the third stage of expansion at
Syncrude. The Aurora 2 mining facilities were completed in
October on budget and on schedule, and production began
by late 2003. Construction of the new upgrader was about 
35-percent complete by year-end, and Syncrude Canada Ltd.
expects it to be commissioned by late 2005. The Syncrude
project team is developing plans to address increased cost
pressures on this aspect of the expansion.

The Kearl oil-sands mining project was advanced in 2003
with the initiation of a 200-well delineation drilling program
on Imperial’s two wholly owned leases. Development activities
will continue in 2004 to better define available mining resources
and evaluate a range of upgrading options. The project
participants, Imperial and ExxonMobil Canada, are investigating
the potential development of minable bitumen on three oil-sands
leases, some 70 kilometres north of Fort McMurray. A phased
approach is being assessed, and the project may have the
potential to produce up to a total of 200,000 barrels a day.

Mackenzie gas project

Imperial leads the Mackenzie gas project, which seeks to
develop about six trillion cubic feet (TCF) of natural gas resource
in the Mackenzie River delta of Canada’s western Arctic – an
important project for future North American gas supply. The
largest of three major fields planned for development is
Imperial’s Taglu field, with about three TCF of gas. 

The project design being advanced for regulatory filing is for
a pipeline with an initial capacity of 1.2 billion cubic feet of
gas a day (50 percent greater than the expected productive
capacity of the three major discovered fields) and includes the
flexibility to increase capacity up to 1.8 billion cubic feet a day.
This would allow for additional northern gas to be brought to
southern markets.

By year-end 2003, Imperial had completed about one million
work hours on the project and had held more than 600 meetings
and consultations with parties including aboriginal groups, local
communities, government officials, regulatory agencies and
potential gas shippers.

In June, as project operator, Imperial filed a Preliminary
Information Package with regulatory agencies, an important
milestone. This followed successful negotiations with other co-
venturers, including the Aboriginal Pipeline Group (APG), 

Annual report 2003

which represents the interests of the Aboriginal Peoples in
the North. APG participation is an integral part of the project
and represents an historic advance for aboriginal involvement
in commercial developments of this type.

Another milestone was passed in late 2003 when the
application for Commercial Discovery Declaration for the Taglu
field was filed with the National Energy Board. Assuming that
the regulators proceed on the timelines described in their June
2002 Cooperation Plan, filing of the main regulatory applications
for the project is expected to take place mid-2004.

Community engagement has been critical to the success of the
Mackenzie gas project. Building enduring relationships with
Canada’s northern communities is an important component of
Imperial’s ongoing operations and development initiatives.

Conventional Western Canada 

In Western Canada, full production from the natural gas cap
at Imperial’s Wizard Lake oil field in Alberta began in July 2003.
Production rates of about 180 million cubic feet a day will be
achieved in 2004 once gas plant capacity is available and are
expected to continue through 2006. Also, in November, the first
natural gas was produced from the Gwillim field in northeastern
British Columbia. Additional development of this field is planned.

Offshore East Coast

In East Coast operations, natural gas production from Imperial’s
nine-percent interest in the Sable offshore energy project
averaged 40 million cubic feet a day before royalties. During
2003, production began from a fourth Sable field, Alma, and
construction was started on facilities for a fifth field, South
Venture. Funding was also approved for a natural gas
compression facility that will service production from all
Sable fields by late 2006.

Balvenie, a deepwater exploration well drilled in mid-2003 off
the east coast of Nova Scotia, did not encounter commercial
quantities of gas and was abandoned. Imperial continues to
monitor industry activity in the region, where it retains other
exploration licences.

In December, Imperial acquired a 25-percent interest in the
exploration rights for eight deepwater parcels in the Orphan
Basin, off the east coast of Newfoundland. This region is
considered to have high potential but is located in a harsh
offshore environment and is a high-risk, high-cost area. Plans 
are being developed with co-venturers ExxonMobil Canada Ltd. 
(25 percent) and Chevron Canada Resources (50 percent) for
potential seismic work in 2004. Imperial’s share of proposed
exploration spending on this acreage totals $168 million, with 
a minimum commitment of $42 million.

Petroleum
products

Imperial continues to upgrade its network of retail
outlets (above). In addition to fuels, petroleum
provides the feedstock for thousands of products and
materials that are essential to our way of life (below).

Imperial’s petroleum products operations achieved record
earnings of $407 million in 2003, supported by increased
sales and strong industry refining and marketing margins.
Return on average capital employed was 16 percent and cash
flow from earnings was $719 million, of which $478 million
was reinvested in the business.

Petroleum products

The company’s strategy of focusing relentlessly on providing
the best offer to customers, having best-in-class costs and using
capital efficiently and effectively continued to serve shareholders
well. At the end of 2003, all major business units in petroleum
products were at first-quartile unit-cost levels, and some were
best-in-class. Sales of refined products were up from 2002 as
Imperial retained the leading position in every major market
segment.

In the retail automotive business, the company’s leading market
share was increased with continuing improvements to products
and services. 

At the end of 2003:
• The retail network included 787 company-owned sites.

Average productivity per site for 2003 was 5.2 million litres a
year, up six percent from 2002. Under an ongoing program to
improve the network, Imperial built nine new sites, rebuilt 17
and upgraded three. 

• The company’s network of about 650 Esso convenience

stores across Canada, including On the Run and Tiger Express,
was the second largest in Canada. On the Run was recently
selected as the North American convenience store chain of
the year by Convenience Store Decisions magazine. In 2003,
65 new On the Run stores were added. Convenience-store
sales rose by about nine percent in 2003, well above the
industry average. Imperial’s network of about 400 sites with
car-wash facilities is the largest in the industry.

• The number of Esso retail sites providing Tim Hortons food
and refreshments had increased to more than 300 from
270 in 2002, as this strategic alliance continued to benefit
both companies.

agency business. Designed to reduce costs and increase
efficiency, the project streamlined this business by replacing 
a network of rural bulk plants with a network of primary and
secondary distribution terminals. In 2003, productivity per site
quadrupled to an average of about 25 million litres.

Imperial maintained its market-leading share of the finished
lubricants market in Canada and continues to be the only
supplier with manufacturing, blending and packaging capability
in both the east and west. The company is also the exclusive
Canadian marketer of Mobil products, for which sales almost
doubled in 2003 from 2002. Through its world-leading lubricants
research capability, the company commercialized 37 new
products in 2003.

A centralized customer order and integrated management
system was implemented during the year, completing a

Freeing up working capital  
for more productive use

During 2003, the ancillary equipment-servicing feature of
Imperial’s heating oil business was sold to Sears Canada Inc.
Under a marketing agreement, Sears will provide equipment
servicing for Esso Home Comfort customers, while promoting
Imperial as the preferred supplier of heating oil.

A continued focus on reducing working capital lowered the
number of days for which product is held in inventory by a
further four percent versus 2002. Over the last 10 years, this
has been reduced by about 25 percent. The reduction in 2003
freed up more than $35 million in cash for more productive use. 

Capital expenditures in petroleum products operations were
$478 million in 2003. This included completion of a multi-year
project to enable the company’s refineries to produce low-
sulphur gasoline to meet the requirements of 2004 model-year
automotive technologies. This project, costing about $600 million
and using ExxonMobil proprietary SCANfining technology 
and other modifications, was completed more than a year 
ahead of federal regulatory requirements. As a result, gasolines
produced by Imperial now have one of the lowest sulphur
levels in the world.

Other capital expenditures included construction on a
cogeneration facility in Sarnia and upgrading of the
network of Esso service stations.

Imperial’s refineries and chemical plants also continued
to benefit from the ExxonMobil Global Energy Management
System, a worldwide initiative aimed at improving energy use
in manufacturing operations. Energy efficiency improved by
one percent in 2003, and over the last 30 years, Imperial’s
refineries have improved energy efficiency by more than
40 percent.

Industry-leading performance

Imperial’s chemicals operations generated earnings of 
$37 million, with return on average capital employed of
18 percent and cash flow from earnings of $66 million in
2003. Sales of petrochemical products were 3,300 tonnes 
a day, down slightly from 2002. In this cyclical business, 
2003 was a weak year for the petrochemicals industry in
North America, characterized by relatively high energy and
feedstock costs and soft sales volumes.

The company remains one of Canada’s leading producers 
of chemical products, with the largest market share in North
America for polyethylene used in rotational and injection
molding and the largest share of the Canadian market for
solvents. The Sarnia polyethylene manufacturing facility
is within one day’s trucking of customers representing 
70 percent of North American demand for polyethylene. 
The company’s other chemicals businesses also 
contributed to profitability.

In 2003, the Sarnia polyethylene plant achieved a milestone of
having produced five million tonnes of product, and it remains
one of the most cost-competitive plants in North America.
Through successive low-cost expansions, annual capacity has
been increased from 135,000 tonnes in 1983 to about 450,000
tonnes in 2003.

A new computer-based managing system for chemicals
operations that will improve service to customers throughout
North America was completed in 2003 and became fully
operational in early 2004. It is designed to realize efficiencies
and cost reductions by managing all aspects of the business –
from order processing through product delivery, invoicing,
collection and financial information. 

Capital expenditures in chemicals were $41 million in 2003. This
included chemicals’ share of a 95-megawatt cogeneration facility
under construction at Imperial’s Sarnia refining and chemicals
manufacturing complex. When it begins operation in 2004, the
facility will significantly improve energy efficiency by using
natural gas to generate both electricity and steam simultaneously,
and help to reduce emissions. It is estimated that it will reduce
the net costs of ethylene production by about 10 percent.

Sound governance.
Ethics and integrity above all.

Imperial has maintained a long tradition of sound
governance practices. The company also recognizes
the importance and value of ethics and business
integrity and believes these principles are critical to
long-term sustainable results.

Sound governance practices

Integrity of reporting

Imperial’s corporate governance practices are fully disclosed
and meet the requirements of the Toronto Stock Exchange
and the American Stock Exchange. For example: 
• The majority of members of the board of directors are

nonemployee directors.

• All board committees, including the audit committee,

are comprised of only nonemployee directors. 
• Directors and committees have the right to engage

an outside adviser at the company’s expense.

• Nonemployee directors meet regularly in the absence
of management, and these meetings are chaired by a
nonemployee director.

• The audit committee is finalizing processes for the
confidential handling of employee complaints.

The company was able to meet the governance requirements
of both the Ontario Securities Commission and the United
States’ Sarbanes-Oxley Act with only minor changes to long-
established practices. 

Imperial has determined that its existing reserves booking
practices do not have to change as a consequence of the
Canadian Securities Administrators National Instrument 51-101.

A complete description of Imperial’s governance practices
can be found in the 2003 Management Proxy Circular on the
company’s Web site at www.imperialoil.ca.

Imperial has a simple, straightforward capital structure and
consistently reports its results using clear, transparent
accounting practices. The company does not use special
purpose entities, special adjustments or pro-forma reporting, 
nor does it use derivatives to speculate on the future direction
of currency or commodity prices, and it does not sell forward
future production.

A commitment to maintaining sound financial controls is
supported by the company’s controls integrity management
system. This establishes a framework of clearly defined
expectations that every operation must meet.

Principled people

Employees are a competitive advantage, and the company
strives to be an employer of choice by attracting, developing 
and retaining high-performing, principled people from diverse
backgrounds. 

Providing people with the opportunity to enhance their
professional and technical skills is key to achieving superior
business results. For example, in 2003, about a quarter of our
employees attended the 100 courses offered to assist them in
developing skills applicable throughout the company.

All employees and directors are required to comply with the
company’s business ethics program. Originally developed in the
1970s, the program covers topics such as conflicts of interest,
integrity of dealings both inside and outside the company,
competition law and restrictive trade practices.

Caring about our community

“Nobody gets hurt”

Improving environmental performance

Nothing is more important than the health and safety of
our employees, contractors, neighbours and customers. The
operations integrity management system (OIMS) provides the
framework for the disciplined management of safety, health and
environmental activities. Lloyd’s Register Quality Assurance Ltd.
has attested that OIMS meets the ISO 14001 requirements for
a comprehensive environmental management system.

Imperial’s safety performance continues to be among the best
in Canadian industry, and in 2003, the company had its safest
year on record with the lowest incidence of work-related injuries
and illnesses for employees and contractors combined. The
company’s goal, however, is that “nobody gets hurt,” and Imperial
is committed to continuously improving performance through
education, awareness, training and other programs.

Gas flaring substantially reduced

Recognizing the importance of a healthy environment, Imperial is
committed to continuously improving in this area. For example,
in 2003, the company:
• completed a more than $600-million project to reduce the
sulphur content of Esso-branded gasolines to among the
lowest in the world. 

• spent about $90 million on environmental remediation programs.
• continued to conserve valuable resources and reduce

emissions by recovering natural gas associated with crude oil
production that would otherwise be flared or vented into the
air. Imperial’s 2002 recovery rate of 99.7 percent of associated
gas was ranked the best among Alberta’s top 50 oil producers
for the second consecutive year. 

• continued to pursue ways to improve energy efficiency and
reduce emissions of carbon dioxide and other greenhouse
gases from its operations, and to report annually to Canada’s
Climate Change Voluntary Challenge and Response (VCR)
program. Imperial’s VCR submissions have consistently
achieved a gold-level rating.
invested about $65 million in Sarnia cogeneration facilities,
which use natural gas to produce electricity and steam
simultaneously, thereby reducing total energy consumption
and helping to reduce emissions in Canada. Total project
expenditures are expected to be about $115 million when
completed early in 2004.

•

In 2002, the government of Canada ratified the Kyoto protocol
on climate change. It has not yet introduced any implementing
legislation, and any possible effects on Imperial or its plans
are uncertain. The government has indicated to industry that
its intent is not to discourage energy development and that
the impacts of Kyoto legislation will be contained. Through
industry associations, Imperial continues to work closely with
governments on the implementation of Canada’s response.

Caring for our neighbours

Imperial was proud to assist local communities in 2003: 
• When concern over SARS affected the tourism industry
in Toronto, an “Esso Celebrates Toronto” promotion
encouraged people to come back into the city by offering
discounted gasoline. A portion of all sales – a total of
$250,000 – was donated for research to improve protective
equipment for health-care workers.

• During the power blackout that affected much of Ontario and
when Hurricane Juan hit the East Coast, employees worked
around the clock to maintain fuel supplies for essential
emergency services. 

In recognition of their special needs, disabled drivers can buy
full-serve gasoline for self-serve prices at company-owned Esso
service stations. At sites with both full- and self-serve pumps,
the disabled driver can have the tank filled by an attendant
for the self-serve price. Self-serve retailers will arrange for
assistance at the pump when the customer calls in advance.

A tradition of giving

In 2003, through donations, sponsorships, scholarships 
and grants, Imperial contributed a total of $8.6 million to
communities, groups and organizations that help improve 
the quality of life in Canada. 

The Imperial Oil Foundation donated $6.1 million to more 
than 400 organizations, with an emphasis on programs 
for youth and education. This included $1 million to the 
University of Waterloo to help build the computer-science
capability of high-school girls, and grants totalling about $215,000
to fund environmental and conservation programs. In addition,
Imperial gave 35 awards to 16 universities, totalling $650,000,
under the company’s University Research Award program.

Other contributions included $288,000 for aboriginal
scholarships and educational programs, almost $350,000 for
the Esso Medals of Achievement and other amateur hockey
programs, $274,000 to support public policy organizations and
about $315,000 for local community sponsorships. The company
also contributed $400,000 to Syncrude’s corporate-giving
program, an amount representing Imperial’s 25-percent
ownership share.

In partnership with its employees and annuitants, the company
contributed more than $2.5 million to the 2003 United Way/
Centraide campaigns across Canada. This was Imperial’s highest-
ever contribution, exceeding its 2002 contribution by more 
than $100,000. The Toronto campaign received a Corporate
Support Award for demonstrating exceptional commitment to
the United Way.

Through its volunteer involvement program, Imperial provided
278 grants totalling $270,000 to support organizations to which
employees and annuitants contributed time and effort.

Engagement and dialogue with key communities is an important
component of Imperial’s ongoing operations and development
initiatives. This includes building enduring relationships with
Canada’s aboriginal communities, with a focus on developing 
and implementing mutually beneficial strategies for business
development, employment, education and training within the
aboriginal communities in which we operate.

Listed below are definitions of four of Imperial’s frequently used financial performance measures. The definitions are provided to facilitate
understanding of the terms and how they are calculated. These terms do not have any standardized meaning prescribed by Canadian
generally accepted accounting principles (GAAP) and may not be calculated in the same way as similar measures are by other companies.

Capital employed
Capital employed is a measure of net investment. When viewed from the perspective of how capital is used by the business, it includes the
company’s property, plant and equipment and other assets, less liabilities, excluding both short-term and long-term debt. When viewed from
the perspective of the sources of capital employed for the total company, it includes total debt and shareholders’ equity. Both of these views
include the company’s share of amounts applicable to equity companies.

Return on average capital employed (ROCE)
ROCE is a financial performance ratio. For each of the company’s business segments, ROCE is annual business-segment earnings divided
by average business-segment capital employed (an average of the beginning- and end-of-year amounts). These segment earnings include
Imperial’s share of segment earnings of equity companies, consistent with the definition used for capital employed, and exclude the cost 
of financing. The company’s total ROCE is net earnings excluding the after-tax cost of financing divided by total average capital employed. 
The company has consistently applied its ROCE definition for many years and views it as the best measure of historical capital productivity 
to both evaluate management’s performance and demonstrate to shareholders that capital has been used wisely over the long term.

Operating costs
Operating costs are the combined total of operating, selling, general, exploration, depreciation and depletion expenses from the consolidated
statement of earnings and Imperial’s share of similar costs for equity companies. Operating costs are the costs incurred during the period to
produce, manufacture and otherwise prepare the company’s products for sale – including staffing, maintenance, and other costs to explore
for and produce oil and gas and operate refining and chemical plants. Delivery costs to customers and marketing expenses are also included.
Operating costs exclude the cost of raw materials and those costs incurred in bringing inventory to its existing condition and final storage
prior to delivery to a customer. These expenses are on a before-tax basis. While Imperial’s management is responsible for all revenue and
expense elements of net earnings, operating costs, as defined below, represent the expenses most directly under management’s control.

Cash flow from earnings
Cash flow from earnings is determined by adjusting net earnings for the effects of non-cash items. It measures the extent of cash generated
from the business before the effects of changes in non-cash working capital and before any investing and financing activities by the company.
Cash flow from earnings is a measure used by the company’s management for analysis and evaluation of operating performance and liquidity
of each business segment and for future investment decisions. A reconciliation of net earnings to cash flow from earnings is provided in the
consolidated statement of cash flows on page 30.

RESULTS OF OPERATIONS

Natural resources 

Net earnings in 2003 were $1,682 million or $4.52 a share – the best
year on record – compared with $1,224 million or $3.23 a share in
2002 (2001 – $1,255 million or $3.19 a share). Higher realizations for
natural gas and crude oil and higher industry margins for petroleum
products, partly offset by the negative impact of a higher Canadian
dollar, were the main reasons for the increased earnings.

Total revenues were $19.2 billion, up about 13 percent from 2002.

The return on average capital employed was 24 percent, compared
with 20 percent in 2002 (2001 – 23 percent).

Earnings from natural resources were $1,139 million, up from 
$1,056 million in 2002 (2001 – $957 million). Higher realizations
for natural gas and crude oil and higher production of Cold Lake
bitumen were largely offset by the negative impact of a higher
Canadian dollar.

Resource revenues were $5.6 billion, up from $4.9 billion in 2002
(2001 – $5.3 billion). The main reasons for the increase were higher
prices for natural gas and crude oil and increased production from
Cold Lake. 

Return on average capital employed was 32 percent for the natural
resources segment, compared with 36 percent in 2002 (2001 – 
41 percent), reflecting the company’s significant increase in
investment in the resources business during the past two years.

World oil prices strengthened considerably in early 2003 and
remained relatively strong due to a combination of world supply
concerns and increased world demand. The annual average price 
of Brent crude oil, the most actively traded North Sea crude and a
common benchmark of world oil markets, was $29 (U.S.) a barrel 
in 2003, compared with $25 in 2002 (2001 – $24.50).

and heavy crude. The price of Bow River, a benchmark Canadian
heavy crude oil, increased by four percent in 2003, compared with 
a nine-percent increase in prices for Canadian light crude oil. Average
realizations for Cold Lake bitumen were about two percent lower
than the previous year, as the stronger Canadian dollar offset any
price increases. 

The increase in the company’s realizations on sales of conventional
Canadian crude oil was diminished by the strengthening of the
Canadian dollar. Average realizations during the year were $40.10
(Cdn) a barrel versus $36.81 in 2002 (2001 – $35.56).

Prices for Canadian natural gas in 2003 were higher on average than
in the previous year. The average of 30-day spot prices for natural
gas at the AECO hub in Alberta was about $6.70 a thousand cubic
feet in 2003, up from $4.10 in 2002 (2001 – $6.30).

Average prices for Canadian heavy crude oil were higher in 2003, 
but not as high as those for lighter crude oil, as increased supply of
Canadian heavy crude oil widened the average spread between light 

The company’s average realizations on natural gas sales increased 
to $6.60 a thousand cubic feet from $4.02 in 2002 (2001 – $5.72).

Gross production of crude oil and natural gas liquids (NGLs)
increased to 256,000 barrels a day from 247,000 barrels in 2002
(2001 – 267,000). Net production increased slightly to 225,000
barrels a day from 223,000 barrels in 2002 (2001 – 237,000).

Net bitumen production at the company’s wholly owned facilities
at Cold Lake increased to 116,000 barrels a day from 106,000 barrels
in 2002 (2001 – 121,000). The higher volume was a result of the
initial production cycles from phases 11–13, which began operation
in December 2002. This was offset in part by lower production
from existing operations, due to the cyclic nature of production
at Cold Lake.

The effective royalty rate on Cold Lake production increased in 
2003, as capital expenditures were lower upon the completion of
phases 11–13. The rate increased to 10 percent of production
from five percent in 2002 (2001 – five percent).

Production from the Syncrude operation, in which the company has
a 25-percent interest, decreased during 2003 as increased unplanned
maintenance affected production through much of the year. Gross
production of upgraded crude oil dropped to 211,000 barrels a day
from 229,000 barrels in 2002 (2001 – 223,000). Imperial’s share of
average net production decreased to 52,000 barrels a day from
57,000 barrels in 2002 (2001 – 52,000).

Net production of conventional oil decreased to 35,000 barrels a
day from 39,000 barrels in 2002 (2001 – 42,000) as a result of the
natural decline in western Canadian reservoirs.

Gross production of natural gas decreased to 513 million cubic feet
a day from 530 million in 2002 (2001 – 572 million). Net production

was 457 million cubic feet a day in 2003, down from 463 million in
2002 (2001 – 466 million). Net production available for sale decreased
to 390 million cubic feet a day from 396 million in 2002 (2001 – 
376 million). Lower production as a result of reservoir decline was
mostly offset by production from the new facilities at Wizard Lake 
in Alberta, which were completed in the third quarter of 2003.

(a) Daily volumes are calculated by dividing total volumes for the year by the number of days in the year. Gross production is the company’s share of production (excluding purchases)

before deducting the shares of mineral owners or governments or both. Net production excludes those shares.

(b) Production available for sale excludes amounts used for internal consumption and amounts reinjected. Starting in 2001, production available for sale reflects a change in the supply

of natural gas to company operations from company-produced gas to third-party purchased gas.

(c) Includes natural gas condensate added to the Cold Lake bitumen to facilitate transportation to market by pipeline.
(d) Production of natural gas includes amounts used for internal consumption with the exception of amounts reinjected.

Operating costs increased by 11 percent in 2003. The main factors
were increased costs associated with the newly completed
phases 11–13 and cogeneration facilities at Cold Lake, unplanned
maintenance at Syncrude and increased exploration costs.

Petroleum products 

mainly as a result of the strengthening of industry petroleum
product margins and increased sales volumes, partly offset by
the negative impact of a higher Canadian dollar. 

Revenues were $16.1 billion, up from $14.4 billion in 2002 
(2001 – $14.4 billion).

Net earnings from petroleum products were a record $407 million or
1.3 cents a litre in 2003, up from $127 million or 0.4 cents a litre in
2002 (2001 – $353 million or 1.2 cents a litre). Earnings improved

Return on average capital employed was 16 percent for the petroleum
products segment, compared with six percent in 2002 (2001 – 
16 percent).

Margins were higher in the refining segment of the industry in 2003
compared with those in 2002, as international wholesale product
prices increased more than raw material costs. However, the effects
of higher international margins were reduced partially by a higher
Canadian dollar.

The company’s total sales volumes, including those resulting from
reciprocal supply agreements with other companies, were 85 million
litres a day, compared with 83.1 million litres in 2002 (2001 – 
81.2 million). Excluding sales resulting from reciprocal agreements,
sales were 70.4 million litres a day, compared with 69.2 million litres
in 2002 (2001 – 69.6 million). 

Operating costs increased by about five percent in 2003 from the
previous year, mainly because of higher energy costs and expenses
related to increased sales volumes. 

Chemicals 

Earnings from chemical operations were $37 million in 2003, down
from $52 million in 2002 (2001 – $23 million). Reduced industry
margins on sales of polyethylene as a result of higher feedstock costs
and weaker industry demand were the main reasons for the decrease
in earnings.

Total revenues from chemical operations were $1,232 million,
compared with $1,164 million in 2002 (2001 – $1,175 million).
Gains from higher prices for polyethylene, intermediate chemicals
and aromatics during 2003 more than offset lower sales volumes.

Return on average capital employed was 18 percent for the chemicals
segment, compared with 28 percent in 2002 (2001 – 14 percent).

The average industry price of polyethylene was $1,415 a tonne in
2003, up 15 percent from $1,229 a tonne in 2002 (2001 – $1,284).
However, margins were reduced because of higher feedstock costs,
reflecting increased prices for natural gas.

Sales of chemicals decreased to 3,300 tonnes a day from 3,500 tonnes
in 2002 (2001 – 3,300 tonnes) as a result of reduced demand.

Operating costs in the chemicals segment increased by about
four percent in 2003 mainly because of higher planned capital
project-related expenses.

Imperial Oil Limited

Management’s discussion and analysis of financial condition and results of operations (continued)

Corporate and other

Earnings from corporate and other accounts were positive 
$99 million in 2003, compared with negative $11 million in 2002
(2001 – negative $78 million). The improvement was mainly
attributable to favourable foreign-exchange effects on the company’s
U.S.-dollar-denominated debt. The company retired the remaining
balance of its U.S.-dollar-denominated debt in 2003.

LIQUIDITY AND CAPITAL RESOURCES

Cash flow from earnings was $2,354 million, up from $1,781 million
in 2002 (2001 – $2,016 million), mainly because of increased
earnings. Cash provided from operating activities was $2,194 million,
compared with $1,676 million in 2002 (2001 – $2,004 million). The
increased cash inflow was mainly due to higher earnings, timing of
scheduled income-tax payments and the effects of commodity prices
on receivable and payable balances, partly offset by additional
funding contributions to the company’s registered pension plan.

In June, the company renewed the normal course issuer bid (share
buyback program) for another 12 months. During 2003, the company
purchased more than 16 million shares for $799 million. Since
Imperial initiated its first buyback program in 1995, the company has
purchased 219 million shares – representing about 38 percent of the
total outstanding at the start of the program – with resulting
distributions to shareholders of $5,968 million.

The company declared dividends totalling 87 cents a share in 2003,
up from 84 cents in 2002 (2001 – 83 cents). Regular per-share
dividends paid have increased in each of the past nine years and,
since 1986, payments a share have grown by more than 55 percent.

The company’s financial position remained very strong in 2003.
Following one of the largest capital investment programs in
Imperial’s history as well as funding contributions to the company’s
registered pension plan, the cash balance was $448 million
at year-end, compared with $766 million at the end of 2002 
(2001 – $872 million).

In 2003, the company retired its $600-million (U.S.) variable-rate debt,
due in 2004, for $818 million (Cdn) and replaced it with $818 million
of Canadian-dollar-denominated variable-rate loans from Exxon
Overseas Corporation at interest equivalent to Canadian market rates.

Total debt outstanding, excluding the company’s share of equity
company debt, at the end of 2003 was $1,432 million, compared 
with $1,538 million at the end of 2002 (2001 – $1,489 million). Debt
represented 20 percent of the company’s capital structure at the 
end of 2003, compared with 23 percent at the end of 2002 (2001 –
26 percent).

Debt-related interest expense paid in 2003 was $38 million, down
from $40 million in 2002 (2001 – $77 million). The retirement of the
company’s long-term fixed-rate debt during the past few years was
the main reason for the reduction. The average effective interest rate 
on the company’s debt was 2.9 percent in 2003, compared with 
2.1 percent in 2002 (2001 – 5.1 percent).

Capital and exploration expenditures

Total capital and exploration expenditures were $1,526 million
in 2003, down slightly from $1,600 million in 2002
(2001 – $1,115 million). 

The funds were used mainly to maintain and expand crude oil and
natural gas production capacity, to upgrade refineries to meet 

low-sulphur gasoline requirements and to enhance the company’s
retail network.

For the natural resources segment, about 90 percent of the capital
and exploration expenditures in 2003 was focused on growth
opportunities. The single largest investment during the year was the
company’s share of the Syncrude expansion. The remainder of 2003
investment was directed to advancing the Mackenzie gas project,
drilling for conventional oil and gas in Western Canada, and East
Coast development and deepwater exploration.

Planned capital and exploration expenditures in natural resources
are expected to total about $1 billion in 2004, with nearly 
90 percent of the total focused on growth opportunities. Much of
the expenditure will be directed to the expansion now underway
at Syncrude. Investments are also planned for the ongoing

development drilling at Cold Lake, the Mackenzie gas project,
development of the Sable South Venture field and the Sable
compression platform, as well as further development drilling
in Western Canada. Planned expenditures for exploration and
development drilling, as well as capacity additions in conventional
oil and gas operations, are expected to be about $320 million.

For the petroleum products segment, capital expenditures decreased
to $478 million in 2003, compared with $589 million in 2002 (2001 –
$339 million), primarily because of the completion of the project to
significantly reduce sulphur content in gasoline, which began in 
2001. New investments in 2003 included the products segment’s
$32-million share of capital expenditures on a 95-megawatt
cogeneration facility to improve energy efficiency and reduce emissions
at the petroleum products and chemicals operations in Sarnia. In
addition, almost $60 million was spent on other refinery projects to
improve energy efficiency and increase yield. Major investments were
also made to upgrade the network of Esso retail outlets during the year.

Capital expenditures for the petroleum products segment in 
2004 are expected to be about $450 million. Major items include
investment in refining facilities to reduce the sulphur content in
diesel to meet regulatory requirements and continued enhancements
to the company’s retail network.

Of the capital expenditures for chemicals in 2003, the major
investment was the Sarnia cogeneration project, a joint development
between the petroleum products and chemicals operations at the site.

Planned capital expenditures for chemicals in 2004 will be about 
$20 million. Funds will be used largely to improve energy efficiency
and yields.

Total capital and exploration expenditures for the company in 2004,
which will focus mainly on growth and productivity improvements, 
are expected to total about $1.5 billion and will be financed primarily
from internally generated funds.

During 2003, the company spent more than $310 million on projects
related to reducing the environmental impact of its operations 
and improving safety. This included investments of more than 
$260 million in the company’s four refineries as part of the capital
project to produce low-sulphur gasoline and diesel fuels.

Reporting investments in mineral interests
in oil and gas properties

The accounting standards for business combinations and goodwill
and other intangible assets issued by the Canadian Institute of
Chartered Accountants (CICA) became effective for the company
on July 1, 2001, and January 1, 2002, respectively. These Canadian
standards are harmonized with specific U.S. standards in these
areas. Currently, the Emerging Issues Task Force (EITF) of the
Financial Accounting Standards Board (FASB) is considering the issue
of whether the U.S. standards require interests held under oil, gas
and mineral leases to be separately classified as intangible assets on
the balance sheets of companies in the extractive industries. If such
interests were deemed to be intangible assets by the EITF, mineral
rights to extract oil and gas for both undeveloped and developed
leaseholds would be classified separately from oil and gas properties
as intangible assets on the company’s balance sheet. The EITF
interpretation could potentially have an impact on the Canadian
standards and the company’s financial reporting. Historically, in
accordance with Canadian generally accepted accounting principles
(GAAP), the company has capitalized the cost of oil and gas
leasehold interests and reported these assets as part of tangible
oil and gas property, plant and equipment.

2 6

Imperial Oil Limited

Management’s discussion and analysis of financial condition and results of operations (continued)

This interpretation of the current U.S. standards would only affect
the classification of oil and gas leaseholds on the company’s balance
sheet and would not affect total assets, net worth or cash flows.
The company’s results of operations would not be affected since
these leasehold costs would continue to be amortized in accordance
with GAAP. The amount that is subject to reclassification as of
December 31, 2003, was $935 million and $1,109 million as of
December 31, 2002.

Pension

An independent actuarial valuation of the company’s registered
pension plan was completed in 2003. As a result of the valuation,
the company contributed $500 million to the registered pension plan.
While equity markets improved in 2003 and the company’s contribution
levels increased, the company plans to take a measured approach to
the pace of funding, within the requirements of pension regulations. 

However, pension liabilities need to be assessed in light of the
company’s strong credit position and prudent financial management.
The company has in the past used and expects to continue to use its
strong balance sheet to effectively manage pension liabilities. Future
funding requirements are not expected to affect the company’s
existing capital investment plans or its ability to pursue new
investment opportunities.

Contractual obligations

To more fully explain the company’s financial position, the following

(a) Unconditional purchase obligations mainly pertain to pipeline throughput agreements.
(b) Firm capital commitments related to capital projects, shown on an undiscounted basis, totalled approximately $189 million at the end of 2003, compared with $284 million at year-end

2002. The largest commitment outstanding at year-end 2003 was associated with the company’s share of capital projects at Syncrude ($56 million).

(c) Pension obligations represent the amount by which accumulated benefit obligations (ABO) exceeded the fair value of plan assets. The ABO is the actuarial present value of benefits

attributed to employee service rendered up to the end of the year and is based on current compensation levels. The ABO is less than the (projected) benefit obligation shown in note 5 to
the consolidated financial statements because it does not take into account future compensation levels. It is used instead of the projected benefit obligation because it more truly reflects
the actual benefit obligation at the end of the year. The payments by period include expected contributions to the company’s registered pension plan in 2004 and estimated benefit
payments for unfunded plans in all years. The term ABO used here is consistent with the definition under Statement of Financial Accounting Standards No. 87 issued by the Financial
Accounting Standards Board.

(d) Asset retirement obligations represent the discounted present value of legal obligations associated with site restoration on the retirement of assets with determinable useful lives.
(e) Other long-term agreements include primarily raw material supply and transportation services agreements.

CRITICAL ACCOUNTING POLICIES

The company’s financial statements have been prepared in
accordance with Canadian generally accepted accounting principles
(GAAP) and include estimates that reflect management’s best
judgments. The company’s accounting and financial reporting fairly
reflect its straightforward business model. Imperial does not use
financing structures for the purpose of altering accounting outcomes
or removing debt from the balance sheet. The following summary
provides further information about the critical accounting policies and
the estimates that are made by the company to apply those policies.
It should be read in conjunction with pages 32 to 33.

Oil and gas reserves

Proved oil and gas reserves quantities are used as the basis of
calculating unit-of-production rates for depreciation and evaluating for
impairment. These reserves are the estimated quantities of crude oil,
natural gas and natural gas liquids that geological and engineering
data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs and deposits under existing
economic and operating conditions. The estimation of reserves is an 

ongoing process based on rigorous technical evaluations and
extrapolations of appropriate information. 

While proved reserves have a reasonable certainty of recovery, 
they are based on estimates that are subject to some variability. 
The variability can result in upward or downward revisions in the
previously estimated volumes of proved reserves for existing fields
due to initial study or restudy of (1) already available geologic,
reservoir or production data, or (2) new geologic or reservoir data
obtained from wells. Revisions can also include changes associated 
with improved recovery projects, fiscal terms and significant
changes in development strategy, oil and gas prices or production
equipment/facility capacity. Over time, revisions of proved reserves
for the company have generally resulted in net upward experience-
based changes through effective reservoir management and the
application of new technology. While revisions are an indicator of
variability, they have had little impact on the unit-of-production rates
of depreciation and on impairment testing because the revisions
have been small compared to the large proved reserves base.

Retirement benefits

The company’s pension plan is managed in compliance with the
requirements of governmental authorities and meets funding levels
as determined by independent third-party actuaries. Pension
accounting requires explicit assumptions regarding, among others,
the discount rate for the benefit obligations, the expected rate of
return on plan assets and the long-term rate of future compensation
increases. All pension assumptions are reviewed annually by senior
financial management. These assumptions are adjusted only as
appropriate to reflect long-term changes in market rates and outlook.
The long-term expected rate of return on plan assets of 8.25 percent
used in 2003 compares to actual returns of 9.5 percent and 10 percent
achieved over the last 10- and 20-year periods ending December 31,
2003. If different assumptions are used, the expense and obligations
could increase or decrease as a result. The company’s potential
exposure to change in assumptions is summarized in footnote (e) of
note 5 to the consolidated financial statements. At Imperial,
differences between actual returns on plan assets versus long-term
expected returns are not recorded in the year the differences occur,
but rather are amortized in pension expense as permitted by GAAP,
along with other actuarial gains and losses over the expected
remaining service life of employees. The company uses the fair value
of the plan assets at year-end to determine the amount of the actual
gain or loss that will be amortized and does not use a moving
average value of plan assets. Pension expense represented about
one percent of total expenses in 2003. 

Asset retirement obligations and other environmental liabilities

Legal obligations associated with site restoration on the retirement of
assets with determinable useful lives are recognized when they are
incurred, which is typically at the time the assets are installed. The
obligations are initially measured at fair value and discounted to
present value. Over time the discounted asset retirement obligation
amount will be accreted for the change in its present value, with this
effect included in operating expense. As payments to settle the
obligations occur on an ongoing basis and will continue over the lives
of the operating assets, which can exceed 25 years, the discount rate
will be adjusted only as appropriate to reflect long-term changes in
market rates and outlook. In 2003, the obligations have been 

discounted at six percent and the accretion expense was $20 million,
which was significantly less than one percent of total expenses in the
year. There would be no material impact on the company’s reported
financial results if a different discount rate had been used.

Asset retirement obligations are not recognized for assets with an
indeterminate useful life. For these and non-operating assets, the
company accrues provisions for environmental liabilities when it is
probable that obligations have been incurred and the amount can
be reasonably estimated.

Asset retirement obligations and other environmental liabilities 
are based on engineering estimated costs, taking into account the
anticipated method and extent of remediation consistent with legal
requirements, current technology and the possible use of the
location. Since these estimates are specific to the locations involved,
there are many individual assumptions underlying the company’s
total asset retirement obligations and provision for other
environmental liabilities. While these individual assumptions can
be subject to change, none of them is individually significant
to the company’s reported financial results.

MARKET RISKS AND OTHER UNCERTAINTIES

The company is exposed to a variety of financial, operating and
market risks in the course of its business. Some of these risks are
within the company’s control, while others are not. For those risks
that can be controlled, specific risk-management strategies are
employed to reduce the likelihood of loss. Other risks, such as
changes in international commodity prices and currency-exchange
rates, are beyond the company’s control. The company’s size, 
strong financial position and the complementary nature of its natural
resources, petroleum products and chemicals segments help
mitigate the company’s exposure to changes in these other risks.
The company’s potential exposure to these types of risk is
summarized in the table below.

The company does not use derivative markets to speculate on the
future direction of currency or commodity prices and does not sell
forward any part of production from any business segment. 

The following table shows the estimated annual effect, under current
conditions, of certain sensitivities of the company’s after-tax earnings.

Earnings sensitivities (a)
millions of dollars after tax
Three dollars (U.S.) a barrel change in crude oil prices
Sixty cents a thousand cubic feet change in natural gas prices
One cent a litre change in sales margins for total petroleum products
One cent (U.S.) a pound change in sales margins for polyethylene
One-quarter percent decrease (increase) in short-term interest rates
Eight cents decrease (increase) in the value of the Canadian dollar versus the U.S. dollar

(a) The amount quoted to illustrate the impact of each sensitivity represents a change of about 10 percent in the value of the commodity or rate in question at the end of 2003. Each

sensitivity calculation shows the impact on annual earnings that results from a change in one factor, after tax and royalties and holding all other factors constant. While these sensitivities
are applicable under current conditions, they may not apply proportionately to larger fluctuations.

The sensitivity to changes in the Canadian dollar versus the U.S.
dollar increased from 2002 by about $12 million (after tax) a year for
each one-cent change. This is primarily a result of the retirement of
the U.S.-dollar-denominated debt, which had previously moderated
the impact of foreign-exchange rate changes on commodity prices
and product margins.

The sensitivity to changes in crude oil prices decreased from 2002
by about $13 million (after tax) for each one U.S.-dollar difference. An
increase in the value of the Canadian dollar has lessened the impact
of U.S.-dollar-denominated crude oil prices on the company’s
revenues and earnings.

Auditors’ report

The accompanying consolidated financial statements
and all information in this annual report are the responsibility
of management. The financial statements have been
prepared in accordance with Canadian generally accepted
accounting principles and include certain estimates that
reflect management’s best judgments. Financial information
contained throughout this annual report is consistent with
these financial statements.

Management has established and maintains a system
of internal controls that provides reasonable assurance that
all transactions are accurately recorded, that the financial
statements fairly report the company’s operating and
financial results and that the company’s assets are
safeguarded. The company’s internal audit unit reviews
and evaluates the adequacy of and compliance with
the company’s internal control standards. It is also the
company’s policy to maintain the highest standard 
of ethics in all its activities.

Imperial’s board of directors has approved the information
contained in the financial statements. The board fulfills 
its responsibility regarding the financial statements mainly
through its audit committee, which is composed of the
nonemployee directors. The audit committee reviews the
company’s annual and quarterly financial statements,
accounting practices, business and financial controls, and
internal audit program and its findings. It also recommends
the external auditors to be appointed by the shareholders
at each annual meeting, reviews their audit work plan and
approves their fees.

PricewaterhouseCoopers LLP, an independent firm 
of chartered accountants, was appointed by a vote of
shareholders at the company’s last annual meeting 
to examine the consolidated financial statements and
provide an independent professional opinion.

To the shareholders of Imperial Oil Limited

We have audited the consolidated balance sheets of Imperial
Oil Limited as at December 31, 2003 and 2002 and the
consolidated statements of earnings and cash flows for each
of the three years in the period ended December 31, 2003.
These financial statements are the responsibility of the
company’s management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with Canadian
generally accepted auditing standards. Those standards
require that we plan and perform an audit to obtain
reasonable assurance whether the financial statements are
free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant
estimates made by management, as well as evaluating the
overall financial statement presentation. 

In our opinion, these consolidated financial statements
present fairly, in all material respects, the financial position
of the company as at December 31, 2003 and 2002 and
the results of its operations and its cash flows for each
of the three years in the period ended December 31, 2003
in accordance with Canadian generally accepted 
accounting principles.

Imperial Oil Limited

Summary of significant accounting policies

Principles of consolidation
The consolidated financial statements include
the accounts of Imperial Oil Limited and its
subsidiaries. Intercompany accounts and
transactions are eliminated. Subsidiaries include
those companies in which Imperial has both
an equity interest and the continuing ability to
unilaterally determine strategic operating,
investing and financing policies. Significant
subsidiaries included in the consolidated financial
statements include Imperial Oil Resources
Limited, Imperial Oil Resources N.W.T. Limited,
Imperial Oil Resources Ventures Limited and
McColl-Frontenac Petroleum Inc. All of the above
companies are wholly owned. A significant
portion of the company’s activities in natural
resources is conducted jointly with other
companies. The accounts reflect the company’s
proportionate interest in such activities, including
its 25-percent interest in the Syncrude joint
venture and its nine-percent interest in the Sable
offshore energy project. 

Segment reporting
The company operates its business in Canada
in the following segments: 
Natural resources includes the exploration 
for and production of crude oil and natural gas.
Petroleum products comprises the refining of
crude oil into petroleum products and the
distribution and marketing of these products. 
Chemicals includes the manufacturing and
marketing of various hydrocarbon-based
chemicals and chemical products. 
Corporate and other includes assets and
liabilities that do not specifically relate to
business segments – primarily cash, marketable
securities and long-term debt. Net earnings in
this category primarily include debt-related
charges and interest income. 

Segment accounting policies are the same as
those described in this summary of significant
accounting policies. Natural resources, petroleum
products and chemicals expenses include
amounts allocated from the “corporate and 
other” segment. The allocation is based on a
combination of fee for service, proportional
segment expenses and a three-year average of
capital expenditures. Transfers of assets between
segments are recorded at book amounts. Items
included in capital employed that are not
identifiable by segment are allocated according
to their nature. 

Accounts receivable 
Accounts receivable arise mainly from customer
purchases of the company’s products. Interest is
accrued on overdue accounts (generally those
over 30 days) and is reported in “investment and
other income” in the consolidated statement of
earnings. Interest accrual will be suspended if
collection becomes doubtful. An allowance for
doubtful accounts is established based upon an

assessment of the collectibility of individual larger
account balances and upon historical experience,
economic and judgmental factors collectively for
groups of smaller homogeneous accounts.
Accounts are written off when judged to be
uncollectable.

Inventories
Inventories are recorded at the lower of cost or
net realizable value. The cost of crude oil and
products is determined primarily using the last-in,
first-out (LIFO) method. LIFO was selected over
the alternative first-in, first-out and average cost
methods because it provides a better matching of
current costs with the revenues generated in the
period. 

Inventory costs include expenditures and other
charges, including depreciation, directly or
indirectly incurred in bringing the inventory to 
its existing condition and final storage prior 
to delivery to a customer. Selling and general
expenses are reported as period costs and
excluded from inventory costs.

Investments
The principal investments in companies other
than subsidiaries are accounted for using the
equity method. They are recorded at the original
cost of the investment plus Imperial’s share of
earnings since the investment was made, less
dividends received. Imperial’s share of the after-
tax earnings of these companies is included in
“investment and other income” in the consolidated
statement of earnings. Other investments are
recorded at cost. Dividends from these other
investments are included in “investment and
other income.”

These investments represent interests in
non-publicly traded pipeline companies that
facilitate the sale and purchase of crude oil and
natural gas in the conduct of company operations.
Other parties who also have an equity interest in
these companies share in the risks and rewards
according to their percentage of ownership.
Imperial does not invest in these companies in
order to remove liabilities from its balance sheet. 

Property, plant and equipment
Property, plant and equipment are recorded
at cost. 

Investment tax credits and other similar grants
are treated as a reduction of the capitalized cost
of the asset to which they apply. 

If the well is successful, the costs remain
capitalized; otherwise they are expensed.
Capitalized exploration costs are re-evaluated
annually. All other exploration costs are expensed
as incurred. Development costs, including the
cost of natural gas and natural gas liquids used 
as injectants in enhanced (tertiary) oil-recovery
projects, are capitalized.

Imperial selected the successful-efforts method
over the alternative full-cost method of
accounting because it provides a more timely
accounting of the success or failure of exploration
and production activities.

Maintenance and repair costs, including planned
major maintenance, are expensed as incurred.
Improvements that increase or prolong the
service life or capacity of an asset are capitalized. 

Production costs are expensed as incurred.
Production involves lifting the oil and gas to the
surface and gathering, treating, field processing
and field storage of the oil and gas. The
production function normally terminates at the
outlet valve on the lease or field production
storage tank. Production costs are those incurred
to operate and maintain the company’s wells and
related equipment and facilities. They become
part of the cost of oil and gas produced.

Depreciation and depletion for assets associated
with producing properties begin at the time when
production commences on a regular basis.
Depreciation for other assets begins when the
asset is in place and ready for its intended use.
Assets under construction are not depreciated
or depleted. Depreciation and depletion are
calculated using the unit-of-production method
for producing properties, including capitalized
exploratory drilling and development costs.
Depreciation of other plant and equipment is
calculated using the straight-line method, based
on the estimated service life of the asset. In
general, refineries are depreciated over 25 years;
other major assets, including chemical plants and
service stations, are depreciated over 20 years. 

Proved oil and gas properties held and used by
the company are reviewed for impairment
whenever events or changes in circumstances
indicate that the carrying amounts may not be
recoverable. Assets are grouped at the lowest
level for which there are identifiable cash flows
that are largely independent of the cash flows of
other groups of assets.

The company follows the successful-efforts
method of accounting for its exploration and
development activities. Under this method, 
costs of exploration acreage are capitalized and
amortized over the period of exploration or until a
discovery is made. Costs of exploration wells are
capitalized until their success can be determined.

The company estimates the future undiscounted
cash flows of the affected properties to judge the
recoverability of carrying amounts. Cash flows
used in impairment evaluations are developed
using annually updated corporate plan investment
evaluation assumptions for crude oil commodity
prices and foreign-currency exchange rates.

Annual report 2003

3 3

Annual volumes are based on individual field
production profiles, which are also updated
annually. Prices for natural gas and other products
sold under contract are based on corporate
plan assumptions developed annually by major
contracts and also for investment evaluation
purposes.

Gains or losses on assets sold are included
in “investment and other income” in the
consolidated statement of earnings. 

Goodwill and other intangible assets
Goodwill and intangible assets with indefinite
lives are not subject to amortization. These assets
are tested for impairment annually or more
frequently if events or circumstances indicate
the assets might be impaired. Impairment losses
are recognized in current period earnings. The
evaluation for impairment of goodwill is based on
a comparison of the carrying values of goodwill
and associated operating assets with the
estimated present value of net cash flows from
those operating assets. 

Intangible assets with determinable useful lives
are amortized over the estimated service lives
of the assets. Computer software development
costs are amortized over a maximum of 15 
years and customer lists are amortized over 
a maximum of 10 years. The amortization is
included in “depreciation and depletion” in 
the consolidated statement of earnings.

Asset retirement obligations and
other environmental liabilities
Legal obligations associated with site restoration
on the retirement of assets with determinable
useful lives are recognized when they are
incurred, which is typically at the time the 
assets are installed. The obligations are initially
measured at fair value and discounted to present
value. A corresponding amount equal to that of
the initial obligation is added to the capitalized
costs of the related asset. Over time the
discounted asset retirement obligation amount
will be accreted for the change in its present
value, and the initial capitalized costs will 
be depreciated over the useful lives of the 
related assets.

No asset retirement obligations are set up
for assets with an indeterminate useful life.
Provision for environmental liabilities of these and
non-operating assets is made when it is probable
that obligations have been incurred and the
amount can be reasonably estimated. The fair
values of asset retirement obligations and other
provisions for environmental liabilities are
determined based on engineering estimated
costs, taking into account the anticipated method
and extent of remediation consistent with legal
requirements, current technology and the
possible use of the location.

Foreign-currency translation
Monetary assets and liabilities in foreign
currencies have been translated at the rates
of exchange prevailing on December 31.
Any exchange gains or losses are recognized
in earnings. 

Financial instruments
Financial instruments are initially recorded at
historical cost. If subsequent circumstances
indicate that a decline in the fair value of a financial
asset is other than temporary, the financial asset is
written down to its fair value. Unless otherwise
indicated, the fair values of financial instruments
approximate their recorded amounts. 

The fair values of cash, marketable securities,
accounts receivable and current liabilities
approximate recorded amounts because of the
short period to receipt or payment of cash. The
fair value of the company’s long-term debt is
estimated based on quoted market prices for 
the same or similar issues or on the current
rates offered to the company for debt of the
same duration to maturity. The fair values of
other financial instruments held by the company
are estimated primarily by discounting future
cash flows, using current rates for similar
financial instruments under similar credit risk
and maturity conditions. 

The company does not use financing structures
for the purpose of altering accounting outcomes
or removing debt from the balance sheet.
The company makes limited use of derivatives.
Derivative instruments are not held for
trading purposes.

Revenues
Revenues associated with sales of crude 
oil, natural gas, petroleum and chemical products
and other items are recorded when the products
are delivered. Delivery occurs when the customer
has taken title and has assumed the risks and
rewards of ownership, prices are fixed or
determinable and collectibility is reasonably
assured. The company does not enter into
ongoing arrangements whereby it is required to
repurchase its products, nor does the company
provide the customer with a right of return. 

Revenues include amounts billed to customers
for shipping and handling. Shipping and handling
costs incurred up to the point of final storage
prior to delivery to a customer are included in
“purchases of crude oil and products” in the
consolidated statement of earnings. Delivery
costs from final storage to customer are
recorded as a marketing expense in selling
and general expenses.

Stock-based compensation
The company accounts for its stock-based
compensation programs, except for the incentive
stock options granted in April 2002, by using the
fair-value-based method. Under this method,
compensation expense related to the units of
these programs is measured by the fair value of
the unit and is recorded in the consolidated
statement of earnings over the vesting period.

As permitted by the new Canadian Institute of
Chartered Accountants (CICA) standard on
accounting for stock-based compensation, the
company continues to apply the intrinsic-value-
based method of accounting for the incentive
stock options granted in April 2002. Under this
method, compensation expense is not recognized
on the issuance of stock options as long as the
exercise price is equal to the market value at the
date of grant.

Consumer taxes
Taxes levied on the consumer and collected 
by the company are excluded from the
consolidated statement of earnings. These are
primarily provincial taxes on motor fuels and 
the federal goods and services tax. 

Interest costs
Interest costs are expensed as incurred and
included in “financing costs” in the consolidated
statement of earnings. 

Accounting principles
The consolidated financial statements have been
prepared in accordance with generally accepted
accounting principles (GAAP) in Canada. Form 
10-K, filed with the United States Securities and
Exchange Commission, includes a description of
the differences between GAAP in Canada and in
the United States as they apply to the company. 

Effective January 1, 2003, the company has
adopted the new CICA standards on accounting
for asset retirement obligations. The impact of
adopting this new standard is described in note 2
to the consolidated financial statements on 
page 35. The company has early adopted the
additional disclosure requirements by the CICA
on employee future benefits, as shown in 
note 5 on page 37. The company has also early
adopted the new CICA standard on stock-based
compensation with no impact on its accounting
or reporting.

(h) Includes property, plant and equipment under construction of $1,426 million (2002 – $1,275 million).

2. Reporting changes

Effective January 1, 2003, the company implemented reporting changes to reflect the new accounting standard of the Canadian
Institute of Chartered Accountants (CICA) dealing with accounting for asset retirement obligations. The new CICA standard changes
the method of accruing for certain site-restoration costs. Under the new standard, the fair values of asset retirement obligations are
recorded as liabilities on a discounted basis when they are incurred, which is typically at the time the related assets are installed. Amounts
recorded for the related assets are increased by the amount of these obligations. Over time the liabilities will be accreted for the change
in their present value, and the initial capitalized costs will be depreciated over the useful lives of the related assets. There are no asset
retirement liabilities set up for those assets that have an indeterminate useful life.

3 6

Imperial Oil Limited

Notes to consolidated financial statements (continued)

Reporting changes (continued)
Estimated cash flows have been discounted at six percent. Implementation of the new standard has reduced environmental liabilities
by $28 million to $462 million as of December 31, 2003. The total undiscounted amount of the estimated cash flows required to settle
the obligations is $895 million. Payments to settle the obligations occur on an ongoing basis and will continue over the lives of the
operating assets, which can exceed 25 years. This change in accounting standard has no impact on the cash flow profile of the company.
The new standard has been applied retroactively, and the financial statements of prior periods have been restated.

The impact of adopting the new standard of accounting for asset retirement obligations on the consolidated balance sheet and
statement of earnings is:

Changes in consolidated balance sheet

millions of dollars – increase/(decrease)
Property, plant and equipment  
Total assets  

Other long-term obligations

(a) During the first half of 2003, the company redeemed the $600-million (U.S.) variable-rate debt for $818 million (Cdn) and replaced it with long-term variable-rate loans

of $818 million (Cdn) from Exxon Overseas Corporation at interest equivalent to Canadian market rates. The average effective interest rate for the loans was 3.1 percent for 2003.

(b) Principal payments on medium-term notes of $500 million, which have been reclassified to current portion of long-term debt in the balance sheet, are due in 2004. These notes

are extendable up to May 7, 2007, at note holders’ discretion.

(c) The estimated fair value of the long-term debt at December 31, 2003, was $818 million (2002 – $1,446 million).
(d) These obligations primarily relate to the capital lease for marine services, which are to be provided by the lessor commencing in 2004 for a period of 10 years, extendable for

an additional five years. The obligations recorded to date represent the costs incurred by the lessor for the construction of the related marine assets.

(e) Principal payments on long-term loans of $500 million are due in 2005 and $318 million are due in 2006. Principal payments on capital leases of approximately $4 million

a year are due in each of the next five years.

Future income taxes are based on differences between the accounting and tax values of assets and liabilities. These differences in value
are remeasured at each period-end using the tax rates and tax laws expected to apply when those differences are realized or settled in
the future. Components of future income tax liabilities and assets as at December 31 were:

(a) The future income tax expense for the year is the difference in net future income tax liabilities at the beginning and end of the year. 
(b) Net cash outflow from income taxes, plus investment credits earned, were $573 million in 2003 (2002 – $935 million; 2001 – $1,086 million). 
(c) Tax losses can be carried forward indefinitely. 

The operations of the company are complex, and related tax interpretations, regulations and legislation are continually changing. 
As a result, there are usually some tax matters in question. The company believes the provision made for income taxes is adequate.

Employee retirement benefits 
Retirement benefits, which cover almost all retired employees and their surviving spouses, include pension-income and certain health-
care and life-insurance benefits. They are met through funded registered retirement plans and through unfunded supplementary benefits
that are paid directly to recipients. Funding of registered retirement plans complies with federal and provincial pension regulations, and
the company makes contributions to the plans based upon an independent actuarial valuation.

Pension-income benefits consist mainly of company-paid defined benefit plans that are based on years of service and final average
earnings. The company shares in the cost of health-care and life-insurance benefits. The company’s benefit obligations are based on the
projected-benefit method of valuation, which includes employee service to date and present compensation levels as well as a projection
of salaries and service to retirement.

The expense and obligations for both funded and unfunded benefits are determined in accordance with generally accepted Canadian
accounting principles and actuarial procedures. The process for determining retirement-income expense and related obligations includes
making certain long-term assumptions regarding the discount rate, rate of return on plan assets and rate of compensation increases. 

The total obligation for employee retirement benefits exceeded the fair value of plan assets at December 31, 2003, by $1,357 million
(2002 – $1,780 million), $975 million (2002 – $1,426 million) of which was related to pension benefits and $382 million (2002 – 
$354 million) was related to other post-retirement benefits. The obligation and pension expense can vary significantly with changes in
the assumptions used to estimate the obligation and the expected return on plan assets.

The company establishes the long-term expected rate of return by developing a forward-looking long-term return assumption for each
asset class, taking into account factors such as the expected real return for the specific asset class and inflation. A single, long-term rate
of return is then calculated as the weighted average of the target asset allocation and the long-term return assumption for each asset
class. The 2003 long-term expected rate of return of 8.25 percent used in the calculations of pension expense compares to an actual
rate of return over the past decade of 9.5 percent.

The company’s investment strategy for benefit plan assets reflects a long-term view, a careful assessment of the risks inherent in
various asset classes and broad diversification to reduce the risk of the total portfolio. The company primarily invests in funds that follow
an index-based strategy to achieve its objectives of diversifying risk while minimizing costs. The fund holds Imperial Oil Limited common
shares only to the extent necessary to replicate the relevant equity index. Asset-liability studies, or simulations of the interaction of cash
flows associated with both assets and liabilities, are periodically used to establish the preferred target asset allocation. The target asset
allocation for equity securities reflects the long-term nature of the liability. The balance of the fund is targeted to debt securities.

(a) Additional expenses include contributions to defined contribution plans, primarily the employee savings plan, of $31 million in 2003 (2002 – $30 million; 2001 – $23 million).
(b) The most recent independent actuarial valuation was as at June 30, 2003. The measurement date used to determine the plan assets and the benefit obligations was December 31, 2003.
(c) Unrecorded assets/(liabilities) are amortized over the average remaining service life of employees, which for 2004 and subsequent years is 13 years (2003 – 13.5 years; 

2002 – 13.5 years).

(d) Prepaid benefit costs are included in investments and other long-term assets on the consolidated balance sheet.
(e) A one-percent change in the assumptions at which retirement liabilities could be effectively settled is as follows: 

millions of dollars

Derivative financial instruments
No significant energy derivatives, foreign-exchange forward contracts or currency and interest-rate swaps were transacted in the past
three years. The company maintains a system of controls that includes a policy covering the authorization, reporting and monitoring of
derivative activity.

Incentive compensation programs
Incentive compensation programs are designed to retain selected employees, reward them for high performance and promote individual
contribution to sustained improvement in the company’s future business performance and shareholder value.

Incentive share units, deferred share units, earnings bonus units and restricted stock units
Incentive share units have value if the market price of the company’s common shares when the unit is exercised exceeds the market
value when the unit was issued. The issue price of incentive share units is the closing price of the company’s shares on the Toronto
Stock Exchange on the grant date. Up to 50 percent of the units may be exercised after one year from issuance; an additional 25 percent
may be exercised after two years; and the remaining 25 percent may be exercised after three years. Incentive share units are eligible for
exercise up to 10 years from issuance. The units may expire earlier if employment is terminated other than by retirement, death or
disability.

The deferred share unit plan is made available to selected executives and nonemployee directors. The selected executives can elect to
receive all or part of their performance bonus compensation in units and the nonemployee directors can elect to receive all or part of
their directors’ fees in units. The number of units granted to executives is determined by dividing the amount of the bonus elected to
be received as deferred share units by the average of the closing prices of the company’s shares on the Toronto Stock Exchange for the
five consecutive trading days immediately prior to the date that the bonus would have been paid. The number of units granted to a
nonemployee director is determined at the end of each calendar quarter by dividing the amount of directors’ fees for the calendar 
quarter that the nonemployee director elected to receive as deferred share units by the average closing price of the company’s shares
for the five consecutive trading days immediately prior to the last day of the calendar quarter. Additional units are granted based on the
cash dividend payable on the company’s shares divided by the average closing price immediately prior to the payment date for that
dividend and multiplying the resulting number by the number of deferred share units held by the recipient.

Deferred share units cannot be exercised until after termination of employment with the company or resignation as a director and
must be exercised no later than December 31 of the year following termination or resignation. On the exercise date, the cash value
to be received for the units is determined based on the average closing price of the company’s shares for the five consecutive trading
days immediately prior to the date of exercise.

The earnings bonus unit plan is available to selected executives. Each earnings bonus unit entitles the recipient to receive an amount
equal to the company’s cumulative net earnings per common share as announced each quarter beginning after the grant. Payout occurs
on the fifth anniversary of the grant or when the maximum settlement value per unit is reached, if earlier. Earnings bonus units may
expire if employment is terminated other than by death or disability.

Under the restricted stock unit plan, each unit entitles the recipient to the conditional right to receive from the company, upon exercise,
an amount equal to the closing price of the company’s common shares on the Toronto Stock Exchange on the exercise dates. Fifty percent
of the units are exercised three years following the grant date, and the remainder are exercised seven years following the grant date.

All units require settlement by cash payments with one exception. The restricted stock unit plan was amended for units granted in 2003
and future years by providing that the recipient may receive one common share of the company per unit or elect to receive the cash
payment for the units to be exercised on the seventh anniversary of the grant date.

For deferred share units, a charge is made to expense in the year of grant equal to the cash performance bonus payment and directors’
fees foregone. The company records expense for incentive share, deferred share and restricted stock units based on changes in the
price of common shares in the year. Expense for earnings bonus units is recorded based on the cumulative net earnings per outstanding
common share from issue date, up to the maximum settlement value for the units.

Incentive stock options
In April 2002, incentive stock options were granted for the purchase of the company’s common shares at an exercise price of $46.50 per
share. Up to 50 percent of the options may be exercised on or after January 1, 2003, a further 25 percent may be exercised on or after
January 1, 2004, and the remaining 25 percent may be exercised on or after January 1, 2005. Any unexercised options expire after 
April 29, 2012. The company did not issue incentive stock options in 2003 and has no plans to issue incentive stock options in the future.

The company does not recognize compensation expense on the issuance of stock options because the exercise price is equal to the
market value at the date of grant. If the fair-value-based method of accounting had been adopted, net income and earnings per share 
(on both a basic and diluted basis) for 2003 would have been reduced by $5 million or $0.01 per share (2002 – $16 million or $0.04 per 

Annual report 2003

4 1

share). The average fair value of each option granted during 2002 was $12.70. The fair value was estimated at the grant date using an
option-pricing model with the following weighted average assumptions: risk-free interest rate of 5.7 percent, expected life of five years,
volatility of 25 percent and a dividend yield of 1.9 percent.

The company has purchased shares on the market to fully offset the dilutive effects from the exercise of stock options. The practice is
expected to continue.

(a) Total rental expense incurred for operating leases in 2003 was $124 million (2002 – $124 million; 2001 – $122 million). Operating lease commitments related to joint-venture

activities are not material.

(b) Unconditional purchase obligations are those long-term commitments that are noncancellable or cancellable only under certain conditions. These mainly pertain to pipeline

throughput agreements. Total payments under unconditional purchase obligations were $114 million in 2003 (2002 – $115 million; 2001 – $179 million).

(c) Firm capital commitments related to capital projects, shown on an undiscounted basis, totalled approximately $189 million at the end of 2003 (2002 – $284 million). The largest
commitments outstanding at year-end 2003 were associated with the company’s share of capital projects at Syncrude of $56 million and offshore East Coast of $50 million.
(d) Other long-term agreements include primarily raw material supply and transportation services agreements. Total payments under other long-term agreements were $332 million

in 2003 (2002 – $288 million; 2001 – $264 million). Payments under other long-term agreements related to joint-venture activities are approximately $44 million per year.

Other commitments arising in the normal course of business for operating and capital needs do not materially affect the company’s
consolidated financial position.

The company was contingently liable at December 31, 2003, for a maximum of $163 million relating to guarantees for purchasing
operating equipment and other assets from its rural marketing agents upon expiry of the agency agreement or the death or resignation
of the agent. The company expects that the fair value of the operating equipment and other assets so purchased would cover the
maximum potential amount of future payment under the guarantees.

The company provides in its financial statements for asset retirement obligations and other environmental liabilities (see accounting
policies on page 33). Provision is not made with respect to those manufacturing, distribution and marketing facilities with indeterminate
useful lives for which estimates of these future costs cannot be reasonably determined. These are primarily currently operated sites.
These costs are not expected to have a material effect on the company’s current consolidated financial position.

Imperial Oil Limited

Notes to consolidated financial statements (continued)

Commitments and contingent liabilities (continued)
Various lawsuits are pending against Imperial Oil Limited and its subsidiaries. The actual liability with respect to these lawsuits is not
determinable, but management believes, based on the opinion of counsel, that any liability will not materially affect the company’s
consolidated financial position.

10. Common shares

The number of authorized common shares of the company as at December 31, 2003 was 450,000,000, unchanged from 
December 31, 2002, and December 31, 2001.

From 1995 to 2002, the company purchased shares under eight 12-month normal course share purchase programs, as well as an auction
tender. On June 23, 2003, another 12-month normal course share purchase program was implemented with an allowable purchase of
18.6 million shares (five percent of the total at June 19, 2003), less any shares purchased by the employee savings plan and company
pension fund. The results of these activities are shown below.

Exxon Mobil Corporation’s participation in the above maintained its ownership interest in Imperial at 69.6 percent. 

The excess of the purchase cost over the stated value of shares purchased has been recorded as a distribution of retained earnings.

In 2003, net earnings included an after-tax gain of $9 million (2002 – $2 million loss; 2001 – $18 million gain) attributable to the effect 
of changes in last-in, first-out (LIFO) inventories. The replacement cost of inventories was estimated to exceed their LIFO carrying values
at December 31, 2003, by $797 million (2002 – $941 million). Inventories of crude oil and products at year-end consisted of the

Research and development costs in 2003 were $63 million (2002 – $64 million; 2001 – $71 million) before investment tax credits 
earned on these expenditures of $10 million (2002 – $10 million; 2001 – $6 million). The net costs are included in expenses due to 
the uncertainty of future benefits.

Cash flow from earnings included dividends of $15 million received from equity investments in 2003 (2002 – $18 million; 2001 – $10 million).

Accounts receivable included allowance for doubtful accounts of $13 million in 2003 (2002 – $13 million).

(a) Cash interest payments in 2003 were $38 million (2002 – $41 million; 2001 – $99 million). The weighted-average interest rate on short-term debt in 2003 was 3.1 percent 

(2002 – 2.4 percent). The average effective interest rate on the company’s debt was 2.9 percent in 2003 (2002 – 2.1 percent).

13. Transactions with Exxon Mobil Corporation and affiliated companies (ExxonMobil) 

Revenues and expenses of the company also include the results of transactions with ExxonMobil in the normal course of operations.
These were conducted on terms as favourable as they would have been with unrelated parties and primarily consisted of the purchase
and sale of crude oil, petroleum and chemical products, as well as transportation, technical and engineering services. Transactions with
ExxonMobil also included amounts paid and received in connection with the company’s participation in a number of natural resources
joint-venture operations in Canada. The company has an existing agreement with ExxonMobil Canada to share common business and
operational support services that allow the companies to consolidate duplicate work and systems. The amounts paid or received have
been reflected in the statement of earnings as shown in the table below.

(a)  Sales of crude oil to consolidated affiliates are at market value, using posted field prices. Sales of natural gas liquids to consolidated affiliates are at prices estimated to

be obtainable in a competitive, arm’s-length transaction. Total sales exclude the sale of natural gas and natural gas liquids purchased for resale, as well as royalty payments.
These items are reported gross in note 1 in “Total revenues” and in “Purchases of crude oil and products.” 

(b)  “Property costs” are payments for rights to explore for petroleum and natural gas and for purchased reserves (acquired tangible and intangible assets such as gas plants,
production facilities and producing-well costs are included under “Producing assets”). “Proved” represents areas where successful drilling has delineated a field capable
of production. “Unproved” represents all other areas.

(a)  Net reserves are the company’s share of reserves after deducting the shares of mineral owners or governments or both. All reported reserves are located in Canada.

Reserves of natural gas are calculated at a pressure of 14.73 pounds per square inch at 60°F.

Crude oil and natural gas reserve estimates, excluding Syncrude, are based on geological and engineering data, which have demonstrated
with reasonable certainty that these reserves are recoverable in future years from known reservoirs under existing economic and operating
conditions; i.e., prices and costs as of the date the estimate is made. Reserves of crude oil at Cold Lake are those estimated to be
recoverable from the existing experimental pilot plants and commercial phases 1 through 13. The calculation of reserves of crude oil at
Syncrude is based on the company’s participating interest in the production permit granted in October 1979 and as subsequently amended 
by the Province of Alberta.

Net proved reserves are determined by deducting the estimated future share of mineral owners or governments or both. For conventional
crude oil (excluding enhanced oil-recovery projects) and natural gas, net proved reserves are based on estimated future royalty rates
representative of those existing as of the date the estimate is made. Actual future royalty rates may vary with production and price. For
enhanced oil-recovery projects, Syncrude and Cold Lake, net proved reserves are based on the company’s best estimate of average royalty
rates over the life of each project. Actual future royalty rates may vary with production, price and costs.

Reserves data do not include certain resources of crude oil and natural gas such as those discovered in the Beaufort Sea-Mackenzie Delta 
and the Arctic islands, or the resources contained in oil sands other than those attributable to Syncrude, the Cold Lake pilot area and phases 
1 through 13 of Cold Lake production operations.

In 2003, Imperial’s net proved reserves of crude oil and NGLs decreased by 77 million barrels, while the net proved reserves of natural gas
decreased by 201 billion cubic feet. Production in 2003 totalled 83 million barrels of crude oil and NGLs and 167 billion cubic feet of natural
gas. Revision of previous estimates and improved recovery increased reserves of crude oil and NGLs by six million barrels and decreased
reserves of natural gas by 40 billion cubic feet. Discoveries and extensions in 2003 totalled six billion cubic feet of natural gas.

Oil-equivalent barrels (OEB) may be misleading, particularly if used in isolation. An OEB conversion ratio of 6,000 cubic feet to one barrel is
based on an energy-equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the
well head.

(a) Exxon Mobil Corporation owns 69.6 percent of Imperial’s shares. 
(b) Closing share price at December 31, divided by net earnings per share – basic and diluted.
(c) The fourth-quarter dividend is paid on January 1 of the succeeding year.

Information for security holders outside Canada
Cash dividends paid to shareholders resident in countries with which Canada has an income tax convention are usually
subject to a Canadian nonresident withholding tax of 15 percent. 

The withholding tax is reduced to five percent on dividends paid to a corporation resident in the United States that owns
at least 10 percent of the voting shares of Imperial. 

Imperial Oil Limited is a qualified foreign corporation for purposes of the new reduced U.S. capital gains tax rates (15 percent
and five percent for certain individuals) which are applicable to dividends paid by U.S. domestic corporations and qualified
foreign corporations. 

There is no Canadian tax on gains from selling shares or debt instruments owned by nonresidents not carrying on business
in Canada.

Valuation day price
For capital gains purposes, Imperial’s common shares were quoted at $10.50 a share on December 31, 1971, and $15.29 on
February 22, 1994. Both amounts are restated for the 1998 three-for-one share split.

Dividend reinvestment and share purchase plan
This plan provides shareholders with two ways to add to their
shareholdings at a reduced cost. The plan enables shareholders
to reinvest their cash dividends in additional shares at an average
market price. Shareholders can also invest between $50 and
$5,000 each calendar quarter in additional shares at an average
market price.

Funds directed to the dividend reinvestment and share purchase
plan are used to buy existing shares on a stock exchange rather
than newly issued shares.
