MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
Those statements in the Management's Discussion and Analysis that are not his-
torical in nature should be deemed forward-looking statements that are inher-
ently uncertain. See "Forward-Looking Statements" on page 40 for a discussion
of the factors which could cause actual results to differ materially from those
projected in such statements.
 
OUTLOOK
The refining and marketing industry is a highly competitive global business
subject to significant volatility. Sun's planning assumptions, including antic-
ipated near-term market trends, are discussed below:
 
 .Sun's operating results will continue to be sensitive to historically unpre-
dictable refining and marketing margins. Because margins will continue to be
driven by competitive pressures, Sun's business plan is focused on improving
operating results by increasing the production of high-value products, improv-
ing the reliability and efficiency of its facilities and reducing operating and
administrative costs per barrel. Sun's operating results improved dramatically
during 1997 as a result of the ongoing implementation of this plan. Overall
production levels increased 6 percent at the Company's mainland refineries with
a large portion of the increase attributable to high-value fuels and chemicals
products. Input to crude units averaged 101 percent of rated capacity. Overall
operating and administrative costs were reduced by approximately $160 million.
In 1998, Sun will continue to operate its refining units near full capacity and
focus on increasing productivity and retail sales volumes.
 
 . Ample supplies of light sweet crude oil will continue to be available. Most
of the crude oil processed in Sun's refining system is light sweet crude oil.
Therefore, the availability of this type of crude oil and its price relative to
alternative heavy sour crude oil will continue to have a significant impact on
Sun's profitability and competitive position.
 
 .Sun's retail gasoline marketing strategy in the Northeast is to improve prof-
itability and the return on capital employed by increasing the number of out-
lets, increasing gasoline throughput and merchandise sales per outlet and re-
ducing marketing and administrative costs per gallon. As a result of its
logistically advantaged refining and distribution assets and its strong branded
marketing presence in this region, Sun believes that it is well positioned to
compete effectively.
 
 .Margins for base oil lubricant products declined in 1997 and will continue to
be under pressure in the near term as new lubricants supply is absorbed in the
marketplace. In order to reduce the impact of unfavorable base oil market con-
ditions, Sun has significantly increased the amount of base oil that it up-
grades into higher-value transportation lubricants. The reconfiguration of the
Puerto Rico refinery in 1997 significantly reduced lower-value fuels production
at this refinery while fully maintaining the volume and quality of lubricants
production. The streamlining of the Puerto Rico facility has improved operating
efficiency, lowered fixed costs and reduced ongoing capital spending and work-
ing capital requirements. Sun will reduce costs further in this business in
1998.
 
 .Overall margins for petrochemicals, particularly for polymer-grade propylene
and cumene, will decline in 1998. Petrochemicals production will increase in
1998, reflecting higher production levels of benzene and ethylene/ethylene ox-
ide. Petrochemical production will also benefit when additional cumene produc-
tion capacity comes on stream at the Philadelphia refinery during the year.
 
 .Operating income in Sun's logistics business in 1998 will approximate the
amount earned during 1997.
 
 
                                                                              28

 
 .Operating income in Sun's cokemaking business will increase significantly af-
 ter commencement of operations at the Company's new cokemaking facility in East
 Chicago, IN, in the first quarter of 1998.

ANALYSIS OF EARNINGS PROFILE OF SUN BUSINESSES
In 1997, Sun Company, Inc. and its subsidiaries earned $263 million, or $2.70
per share of common stock on a diluted basis compared to a net loss of $115
million, or $2.17 per share in 1996 and net income of $140 million, or $1.29
per share in 1995. Excluding the special items shown separately in the Earnings
Profile of Sun Businesses, Sun earned $284 million in 1997, compared to $14
million in 1996 and $131 million in 1995.
 
The $270 million increase in earnings before special items in 1997 was primar-
ily due to record production levels, particularly of high-value fuels and chem-
icals products, and significantly lower operating and administrative expenses
throughout the Company. Also contributing to the improvement were higher aver-
age retail and wholesale gasoline margins and higher chemical margins. Par-
tially offsetting these positive factors were lower base oil margins and the
absence of earnings from Sun's International Production business which was di-
vested in 1996.
 
In 1996, the $117 million decrease in earnings before special items was primar-
ily due to the impact of significantly higher crude oil costs on gasoline, as-
phalt, petrochemical and base oil lubricant margins and on refinery fuel costs.
Also contributing to the decline were higher marketing expenses, increased
planned refinery maintenance activity and the absence of earnings from Suncor
and International Production following their divestments in June 1995 and Sep-
tember 1996, respectively. Partially offsetting these negative factors were
significantly improved middle distillate margins, higher lubricant sales vol-
umes and lower net financing expenses.

*Wholesale sales price less cost of crude oil,
 other feedstocks and purchased refined products.
 
Sun Northeast Refining operating results increased $135 million in 1997 primar-
ily due to a $92 million pretax reduction in operating expenses and signifi-
cantly higher realized margins and sales volumes for wholesale fuels. The in-
crease in margins and sales volumes reflects a significant improvement in pro-
duction levels, particularly for high-value gasoline and distillate products,
in part due to the turnaround and modernization of the 86,000 barrels-per-day
fluid catalytic cracking unit at the Marcus Hook refinery completed in the lat-
ter part of 1996. In addition, wholesale gasoline margins were adversely im-
pacted in 1996 and 1995 by the Company's high cost of MTBE (a component of re-
formulated gasoline) due to a contractual purchase commitment (see Note 13 to
the consolidated financial statements).
 
During 1996, Sun reconfigured its Philadelphia refinery to process only sweet
crude oil and to cease asphalt production. The reconfiguration is part of a
continuing process to integrate the Point Breeze and Girard Point segments of
the refinery. This project has contributed to the substantial improvement in
the Northeast refining system's operating reliability and cost structure in
1997. In connection with the reconfiguration, a $53 million after-tax provision
was established in 1996 primarily to write-off redundant and/or unprofitable
units. This provision is reported as part of the Provision for Write-Down of
Assets and Other Matters shown separately in the Earnings Profile of Sun Busi-
nesses.
 
Sun Northeast Refining operating results decreased $23 million in 1996 primar-
ily due to an $18 million pretax increase in refinery operating expenses and
lower sales volumes, partially offset by higher average wholesale fuels product
margins. The higher operating expenses were due largely to higher refinery fuel
costs resulting from higher crude oil and natural gas prices. The lower sales
volumes were due largely to increased planned refinery maintenance activity.
The increase in wholesale fuels margins reflects significantly higher margins
for middle distillates, largely offset by the adverse impact of higher crude
oil prices on wholesale gasoline and asphalt margins. Wholesale gasoline mar-
gins were adversely impacted in both 1996 and 1995 by the Company's high cost
of making reformulated gasoline.

*Retail sales price less wholesale sales price. The retail sales price is the
 weighted average price received through the various branded marketing
 distribution channels.
 
The $72 million increase in Sunoco Northeast Marketing operating results in
1997 was primarily due to significantly higher average retail gasoline margins
and a $47 million pretax decrease in marketing and administrative expenses.
Partially offsetting these positive factors were 5 percent lower retail gaso-
line sales volumes. Retail gasoline margins were adversely impacted in 1996 and
1995 by the Company's high cost of MTBE.
 
Sunoco Northeast Marketing operating results declined $44 million in 1996 pri-
marily due to lower retail gasoline margins and an $18 million pretax increase
in marketing and administrative expenses. The increase in expenses was due
largely to the impact of a major advertising campaign and higher expenses asso-
ciated with volume increases in company-operated outlets. Partially offsetting
these negative factors was a 2 percent increase in sales volumes.

*Wholesale sales price less the cost of feedstocks and product purchases.
 
Income from Sunoco Chemicals increased $37 million in 1997 largely due to
higher margins and sales volumes reflecting record production levels. Total
petrochemical production for 1997 was 8.8 million barrels (24,100 barrels per
day) versus 1996 production of 6.9 million barrels (18,900 barrels per day).
This 28 percent increase in production volumes was largely a result of refinery
maintenance turnarounds completed in the 1996-97 period at the Philadelphia and
Marcus Hook refineries and the expansion of polymer-grade propylene production
capacity at the Marcus Hook refinery in late 1996.
 
Sunoco Chemicals income decreased $28 million in 1996 primarily due to signifi-
cantly lower margins for most petrochemicals products compared to the strong
margins experienced during 1995. Production shortfalls due to maintenance ac-
tivities at the Company's operating facilities also negatively impacted Sunoco
Chemicals results in 1996.

  *Wholesale sales price of lubricants and fuels less cost of crude oil, other
   feedstocks and purchased refined products.
 **Comprised principally of transportation and industrial lubricants.
***Primarily "lubes-extracted" feedstocks which are transported to the Toledo
   refinery for further processing.
 
Sun Lubricants results improved $15 million in 1997 due primarily to higher
specialty oil lubricant margins and a $16 million pretax decline in operating
expenses. Also contributing to the improvement were higher earnings attribut-
able to the Kendall lubricants business acquired by Sun in November 1996. This
acquisition has increased the amount of base oil production upgraded into
transportation lubricants and has enabled Sun Lubricants to increase its spe-
cialty oil lubricants sales. Partially offsetting these positive factors were
20 percent lower base oil margins.
 
The decline in operating expenses during 1997 was largely attributable to im-
proved operations at the Puerto Rico refinery resulting from the
reconfiguration initiated at this facility in the first quarter of the year.
The changes significantly reduced fuels production at this refinery while fully
maintaining lubricants manufacturing capabilities. The Puerto Rico refinery is
now processing approximately 30,000 barrels per day of reduced crude oil in
lieu of conventional crude oil. Prior to the reconfiguration, this facility had
a crude oil processing capacity of 85,000 barrels per day. Sun Lubricants oper-
ating results for 1996 exclude an $80 million after-tax provision related to
the reconfiguration. This provision is reported as part of the Provision for
Write-Down of Assets and Other Matters shown separately in the Earnings Profile
of Sun Businesses.
 
The $1 million improvement in Sun Lubricants operating results in 1996 was pri-
marily due to higher lubricants sales volumes and higher margins on wholesale
fuels products. These positive factors were essentially offset by lower lubri-
cant margins, principally for base oils, and higher operating and administra-
tive expenses. The increase in expenses was largely attributable to an increase
in refinery fuel costs and production levels.

***Effective January 1, 1998, the rated capacity of the crude unit at the Toledo

   Sunoco MidAmerica Marketing & Refining results improved $43 million in 1997
largely due to an increase in wholesale fuel margins and higher wholesale fuel
sales volumes, reflecting record refinery production levels. Also contributing
to the improvement were higher chemical margins and a $12 million pretax de-
crease in operating expenses. Partially offsetting these positive factors were
lower retail gasoline margins.
 
Sunoco MidAmerica Marketing & Refining results improved $5 million in 1996 due
to higher wholesale fuel margins and sales volumes and a $9 million pretax de-
crease in retail marketing expenses. Partially offsetting these positive fac-
tors were a decline in margins on petrochemicals, largely xylene, and a $22
million pretax increase in refinery expenses resulting from higher refinery
fuel costs and production volumes.

Sunoco Logistics income increased $3 million in 1997 primarily due to higher
throughput at the Nederland, TX, crude oil terminal and in the eastern product
pipeline system. In 1996, Sunoco Logistics results decreased $5 million primar-
ily due to lower eastern product pipeline system throughput and a loss associ-
ated with a pipeline leak, partially offset by higher earnings from joint ven-
ture pipeline operations.

Sun Coke income increased $7 million during 1997 after increasing $6 million in
1996. The increases in earnings during the 1995-97 period were primarily due to
higher margins for coke and improved results from steam coal operations in Ken-
tucky. Sun Coke results included gains from divestments and insurance recov-
eries totalling approximately $2 million after tax in both 1997 and 1996.
 
In November 1996, Sun Coke entered into an agreement to construct, own and op-
erate a $195 million cokemaking facility in East Chicago, IN, which will pro-
duce coke for Inland Steel Company's Indiana Harbor Works steel plant located
adjacent to the new facility. The agreement requires Inland to buy 1.2 million
tons of coke annually on a take-or-pay basis for a period of 15 years commenc-
ing after the cokemaking facility's scheduled first quarter 1998 start-up date.
Additional production of up to 150,000 tons per year will be sold either to In-
land or other steel producers. The plant's coke ovens will utilize Sun Coke's
proprietary heat-recovery cokemaking technology, which is environmentally and
economically superior to the chemical by-product technology currently used by
other coke producers.
 
Net Financing Expenses--Net financing expenses increased $1 million in 1997 af-
ter decreasing $8 million in 1996. The decline in 1996 was primarily due to
lower average total borrowings.
 
Real Estate Operations Held for Sale--For a discussion of Sun's real estate op-
erations held for sale, see Note 2 to the consolidated financial statements.
 
Sun International Production--On September 30, 1996, Sun completed the sale of
its International Production business for $278 million in cash which resulted
in a $125 million after-tax gain. This gain is shown separately in the Earnings
Profile of Sun Businesses. Prior to the divestment, operating results for this
business unit totalled $41 million in 1996 and $57 million in 1995.
 
Canada (Suncor)--On June 8, 1995, Sun divested its remaining 55-percent inter-
est in Suncor Inc., a Canadian integrated oil company, for $770 million, of
which $635 million was received in June 1995 and $135 million was received in
June 1996. This divestment resulted in a $157 million after-tax gain, which is
shown separately in the Earnings Profile of Sun Businesses. Suncor's operating
results totalled $23 million in 1995 prior to the divestment.
 
ANALYSIS OF CONSOLIDATED STATEMENTS OF OPERATIONS
 
Revenues--Total revenues from continuing operations were $10.5 billion in 1997,
$11.3 billion in 1996 and $9.9 billion in 1995. The 7 percent decrease in 1997
was primarily due to lower revenues from resales of purchased crude oil, lower
refined product prices and lower consumer excise taxes, partially offset by
higher refined product sales volumes.
 
In 1996, the 14 percent increase reflects higher refined product sales prices
and volumes and higher revenues from resales of purchased crude oil, partially
offset by the absence of revenues from Canadian refining and marketing opera-
tions as a result of the divestment of Suncor on June 8, 1995.
 
                                                                              34

 
 
Costs and Expenses--Total pretax costs and expenses attributable to continuing
operations were $10.1 billion in 1997, $11.7 billion in 1996 and $9.9 billion
in 1995. The 14 percent decrease in 1997 was primarily due to lower resales of
purchased crude oil and lower crude oil and refined product acquisition costs.
Also contributing to the decrease were reduced operating and administrative ex-
penses reflecting cost containment efforts and a decline in the provisions for
asset write-downs, employee terminations and other matters.
 
The 18 percent increase in costs and expenses in 1996 was primarily due to
higher crude oil and refined product acquisition costs largely as a result of
an increase in crude oil prices, and higher resales of purchased crude oil.
Also contributing to the increase were higher domestic refinery operating ex-
penses attributable principally to higher refinery fuel costs, higher domestic
consumer excise taxes, higher costs related to Sun's cokemaking business and an
increase in the provisions for asset write-downs, employee terminations and
other matters. Partially offsetting these increases were lower costs and ex-
penses related to Canadian refining and marketing operations resulting from the
Suncor divestment and lower interest cost and debt expense due to lower average
borrowings.
 
FINANCIAL CONDITION
 
CAPITAL RESOURCES AND LIQUIDITY
 
Cash and Working Capital--At December 31, 1997, Sun had cash and cash equiva-
lents of $33 million compared to $67 million at December 31, 1996 and had a
working capital deficit of $216 million compared to a working capital deficit
of $282 million at December 31, 1996. Sun's working capital position is consid-
erably stronger than indicated because of the relatively low historical costs
assigned under the LIFO method of accounting for most of the inventories re-
flected in the consolidated balance sheet. The current replacement cost of all
such inventories exceeds their carrying value at December 31, 1997 by $492 mil-
lion. Inventories valued at LIFO, which consist of crude oil and refined prod-
ucts, are readily marketable at their current replacement values. Management
believes that the current levels of Sun's cash and working capital are adequate
to support Sun's ongoing operations.
 
Cash Flows and Financial Capacity--In 1997, Sun's net cash provided by operat-
ing activities ("cash generation") was $452 million compared to $332 million in
1996 and $352 million in 1995. The $120 million increase in cash generation in
1997 was primarily attributable to the significant increase in income before
special items, partially offset by an increase in working capital uses pertain-
ing to operating activities and a reduction in net cash provided by operating
activities of discontinued operations. The $20 million decrease in cash genera-
tion in 1996 was largely due to declines in income before special items and net
cash provided by operating activities of discontinued operations, essentially
offset by a reduction in working capital uses pertaining to operating activi-
ties.
 
Divestment activities have also been a source of cash and in the past have en-
hanced liquidity. During the 1995-97 period, proceeds from divestments totalled
$1,326 million, including $278 million received in 1996 from the sale of the
International Production business and $770 million received in the 1995-96 pe-
riod from the sale of Suncor common stock.
 
Management believes that future cash generation will be sufficient to satisfy
Sun's capital requirements and to pay the current level of cash dividends on
common and preference stock. However, from time to time, the Company's short-
term cash requirements may exceed its cash generation due to various factors
including volatility in crude oil and refined product markets and increases in
capital spending and working capital levels. During those periods, the Company
may supplement its cash generation with proceeds from financing activities.

The Company has a $500 million revolving credit agreement ("Agreement") with
commercial banks that provides access to short-term financing through September
2002. The Company can borrow directly from the participating banks under this
Agreement or use it to support commercial paper issued by Sun. The Company also
has access to short-term financing under non-committed money market facilities.
At December 31, 1997 and 1996, there were no amounts outstanding related to the
above short-term borrowing arrangements.
 
The following table sets forth amounts outstanding related to Sun's other
borrowings:

Sun's debt-to-capital ratio was 36.4 percent at December 31, 1997 compared to
38.2 percent at December 31, 1996. Management believes there is sufficient bor-
rowing capacity available to pursue strategic investment opportunities as they
arise. In addition, the Company has the option of issuing additional common or
preference stock as a means of increasing its equity base; however, there are
no current plans to do so. No commitments have been made with respect to any
investment opportunity which would require the use of a significant portion of
Sun's unused financial capacity.
 
In early 1998, Sun transferred an interest in its cokemaking operations in East
Chicago, IN, to a third party in exchange for $200 million in cash. The trans-
feree is entitled to a preferential return from the cash flows of this
cokemaking operation until certain cumulative return targets have been met. Sun
did not recognize a gain or loss on this transaction.

 *Excludes $74 million attributable to the purchase of the Kendall lubricants
  business and related working capital.
**Excludes capital expenditures of Sun Coke prior to June 30, 1995 while such
  operations were accounted for as an investment held for sale.
 
In 1997, major capital expenditures included: $118 million for the ongoing con-
struction of the $195 million cokemaking facility in East Chicago, IN, sched-
uled to commence operations in the first quarter of 1998; $25 million to begin
the expansion of the Philadelphia refinery's cumene production capacity; $17
million for the scheduled turnaround of various units at the Philadelphia re-
finery including a catcracker, a crude unit and a gasoline reformer; and $46
million largely for service station modernization activities in the Northeast.
 
In 1996, in addition to the $74 million spent to acquire the Kendall lubricants
business (of which $46 million related to working capital), major capital out-
lays included: $81 million for branded marketing activities in the Northeast
mainly for ongoing upgrades of service stations; $76 million for the six-week
scheduled turnaround and modernization of the 86,000 barrel-per-day catalytic
cracking unit, gas plant and ethylene complex at the Marcus Hook refinery; $37

In 1995, major capital expenditures included: $61 million related to service
station conversion and modernization activities; $26 million at the Marcus Hook
refinery to begin the expansion of the propylene unit and to complete expansion
of an ethylene oxide unit; $18 million to complete a cyclohexane plant and ex-
pand benzene extraction capacity at the Marcus Hook refinery and $13 million to
complete the construction of a pipeline connecting the Philadelphia and Marcus
Hook refineries.
 
The 1998 planned capital expenditures include $144 million for growth projects
with four projects comprising approximately 80 percent of the growth spending.
These outlays are: $58 million to complete the construction of the East Chica-
go, IN, cokemaking facility; $25 million to complete the expansion of the Phil-
adelphia refinery's cumene production facilities; $18 million to modernize the
68,000 barrel-per-day catalytic cracking unit at the Philadelphia refinery; and
$17 million to upgrade or acquire Sunoco(R) retail marketing locations in the
Northeast. An additional $273 million is designated for base infrastructure and
legally required spending in 1998, a significant portion of which relates to
projects that will enhance the reliability of the Company's operations. The
base infrastructure spending includes scheduled turnarounds at Sun's refining
facilities and projects that will maintain the high quality image of Sunoco(R)
retail outlets.
 
ENVIRONMENTAL MATTERS
Sun is subject to numerous federal, state and local laws which regulate the
discharge of materials into, or otherwise relate to the protection of, the en-
vironment. These laws have required, and are expected to continue to require,
Sun to make significant expenditures of both a capital and expense nature. The
following table summarizes Sun's expenditures for environmental projects and
compliance activities:

- ------------------------------------------------------------------------

*Capital expenditures for pollution abatement are expected to approximate $35
 and $34 million in 1998 and 1999, respectively.
 
The Clean Air Act establishes stringent criteria for regulating air toxics at
operating facilities by mandating major reductions in allowable emissions and
establishing a more comprehensive list of substances deemed to be air toxics.
The Clean Air Act also requires refiners to market cleaner-burning gasoline
that reduces emissions of certain toxic and conventional pollutants. The Com-
pany has implemented the first phase of the reformulated gasoline regulations
which requires an increase in the minimum quantity of oxygen for certain non-
attainment areas, a reduction in benzene content, and a reduction in summertime
Reid Vapor Pressure ("RVP"). Sun expects to implement the next more stringent
phases of these regulations in 1998 and 2000 with modest capital investment.
 
In order to obtain a secure supply of oxygenates, Sun entered into an off-take
agreement with Belvieu Environmental Fuels ("BEF"), a joint venture in which
Sun is a one-third partner, whereby Sun agreed to purchase all of the MTBE from
BEF's 14,000 barrel-per-day facility. At December 31, 1996, Sun established a
$130 million accrual ($85 million after tax) for estimated losses expected to
be realized with respect to the off-take agreement. During 1997, actual losses
attributable to this agreement totalling $65 million were charged against the
accrual. (See Note 13 to the consolidated financial statements.)
 
The Comprehensive Environmental Response Compensation and Liability Act
("CERCLA") and the Solid Waste Disposal Act as amended by the Resource Conser-
vation and Recovery Act ("RCRA"), and related federal and state laws subject
Sun to the potential obligation to remove or mitigate the environmental effects
of the disposal or
 
37

 
release of certain pollutants at Sun's facilities and at third-party or former-
ly-owned sites. Under CERCLA, Sun is subject to potential joint and several li-
ability for the costs of remediation at sites at which it has been identified
as a "potentially responsible party" ("PRP"). As of December 31, 1997, Sun had
been named as a PRP at 44 sites identified or potentially identifiable as
"Superfund" sites under CERCLA. Sun has reviewed the nature and extent of its
involvement at each site and other relevant circumstances and, based upon the
other parties involved or Sun's negligible participation therein, believes that
its potential liability associated with such sites will not be significant.
 
Under various environmental laws, including RCRA, Sun has initiated corrective
remedial action at Sun's facilities, formerly-owned facilities and third-party
sites and could be required to undertake similar actions at various other
sites. The cost of such remedial actions could be significant but is expected
to be incurred over an extended period of time.
 
Sun establishes accruals related to environmental remediation activities for
work at identified sites where an assessment has indicated that cleanup costs
are probable and reasonably estimable. For a discussion of the accrued liabili-
ties and charges against income related to these activities, see Note 13 to the
consolidated financial statements.
 
On October 4, 1996, Sun filed a complaint in Los Angeles County Superior Court,
Jalisco Corporation, Inc., et al. v. Argonaut Insurance Company, et al. (Case
No. BC 158441), naming more than 45 insurance companies as defendants and seek-
ing recovery under numerous insurance policies for certain environmental expen-
ditures of Sun, including its predecessor companies and subsidiaries, arising
from the ownership and operation of its business and properties. The Company
cannot quantify the ultimate outcome of this litigation which may be protract-
ed.
 
Total future costs for environmental remediation activities will depend upon,
among other things, the identification of any additional sites, the determina-
tion of the extent of the contamination at each site, the timing and nature of
required remedial actions, the technology available and needed to meet the var-
ious existing legal requirements, the nature and extent of future environmental
laws, inflation rates and the determination of Sun's liability at multi-party
sites, if any, in light of the number, participation level and financial via-
bility of other parties.
 
Management believes that the overall expenditures for the matters discussed
above are likely to be significant but are expected to be incurred over an ex-
tended period of time and to be funded from Sun's net cash provided by operat-
ing activities. Although potentially significant with respect to results of op-
erations or cash flows for any one year, management believes that such costs
will not have a material impact on Sun's consolidated financial position or,
over an extended period of time, on Sun's cash flows or liquidity.
 
YEAR 2000 INFORMATION PROCESSING
A comprehensive program is currently underway to evaluate and implement changes
that will be necessary for the Company to accurately process information at and
beyond the Year 2000. The program consists of an evaluation of and changes to
Sun's information technology environment, which includes all software, hardware
and network components, as well as an assessment of the ability of the
Company's major customers and suppliers to conduct business. Management expects
that all of Sun's systems critical to its ongoing business will be Year 2000
compliant by mid-1999. Management also believes that the costs associated with
this project will not be significant in relation to Sun's results of opera-
tions. Furthermore, the Company has not identified any material adverse Year
2000 consequences to date in connection with any of its third-party relation-
ships. However, if any governmental agencies, key customers or key suppliers
are unable to make the necessary computer system changes on a timely basis,
such inability could negatively impact the Company's results of operations.
 
                                                                              38

 
 
DERIVATIVE INSTRUMENTS
Sun uses swaps, options, futures, forwards and other similar derivative con-
tracts to hedge the impact of fluctuations in crude oil, natural gas, refined
product and electricity prices. At December 31, 1997, Sun had swaps and options
outstanding to hedge against significant increases in crude oil prices amount-
ing to approximately 4 million barrels (2 percent) of its expected 1998 crude
oil purchases and had locked in what it considers to be acceptable margins for
approximately 6 million barrels (2 percent) of its anticipated 1998 wholesale
fuel sales.
 
Sun is at risk for possible changes in the market value of all of its deriva-
tive contracts. However, it is anticipated that such risk would be mitigated by
price changes in the underlying hedged transactions. In addition, Sun is ex-
posed to credit risk in the event of nonperformance by counterparties. Manage-
ment believes this risk is negligible as its counterparties are either regu-
lated by exchanges or are major international financial institutions with high
credit ratings. Although most of these derivative contracts are intended to
limit the Company's exposure to rising crude oil prices and/or declining mar-
gins, they could limit the Company's participation in falling crude oil prices
and/or rising margins. For a further discussion of Sun's hedging activities,
see Note 16 to the consolidated financial statements.
 
CASH DIVIDENDS AND SHARE REDEMPTION AND REPURCHASES
The Company has paid cash dividends on a regular quarterly basis since 1904.
Effective with the third quarter of 1995, Sun reduced its quarterly common
stock dividend from $.45 per share to $.25 per share. As a result, the cash
dividends paid on common stock totalled $1.40 per share in 1995 and $1.00 per
share in 1996 and 1997. The Company expects to continue to sustain the quar-
terly common stock cash dividend at its current level.
 
During the third quarter of 1995, Sun exchanged 25 million "depositary shares"
for an equal number of shares of its common stock in a tax-free transaction.
Each depositary share represents ownership of one-half share of the Company's
Series A cumulative preference stock. The depositary shares accrue dividends
quarterly at a rate of $.45 per share, or one-half the rate paid on the prefer-
ence stock. Cash dividends paid on the depositary shares totalled $.90 per
share in 1995 and $1.80 per share in both 1996 and 1997. (See Note 14 to the
consolidated financial statements.)
 
The outstanding depositary shares are redeemable at any time by the Company, in
whole or in part, for common stock at a value which initially equaled $42.40
per depositary share at June 12, 1995 and declines ratably to $40.00 per depos-
itary share at June 11, 1998. As of February 12, 1998, this call price was
$40.27 per depositary share. After June 11, 1998, the Company can redeem the
depositary shares with common shares on a one-for-one basis, subject to adjust-
ment in certain events. If Sun were to do a partial redemption of depositary
shares, it would be done on a pro rata basis. The Company currently intends to
redeem all of the outstanding depositary shares no later than June 12, 1998.
 
The Company repurchased 6,400,000 shares of its common stock in mid-1995
through a tender offer for $192 million and an additional 6,774,500 shares of
common stock and 885,700 depositary shares during the 1995-97 period on the
open market for $250 million. At December 31, 1997, the Company had a remaining
authorization from its Board of Directors to purchase up to $150 million of
Company stock in the open market or through privately negotiated transactions
from time to time depending on prevailing market conditions.

FORWARD-LOOKING STATEMENTS
Those statements in the Management's Discussion and Analysis that are not his-
torical in nature should be deemed forward-looking statements within the mean-
ing of Section 21E of the Securities Exchange Act of 1934. Such statements gen-
erally will be accompanied by words such as "anticipate," "believe," "esti-
mate," "expect," "forecast," "intend," "possible," "potential," "predict,"
"project," or other similar words that convey the uncertainty of future events
or outcomes. Although Sun believes these forward-looking statements are reason-
able, they are based upon a number of assumptions concerning future conditions,
any or all of which may ultimately prove to be inaccurate. Such forward-looking
statements involve risks and are inherently uncertain. Important factors that
could cause actual results to differ materially from those projected in such
statements are discussed below.
 
Sun's operating results are dependent upon the reliability and efficiency of
the Company's operating facilities, the level of operating expenses and hazards
common to operating facilities (including equipment malfunction, explosions,
fires, oil spills and the effects of severe weather conditions). Plans for the
construction, modernization or debottlenecking of refineries, chemical plants
and/or cokemaking facilities, and the utilization and timing of production from
these facilities are subject to many factors, including unplanned delays, and
the issuance of applicable building, environmental and other permits. Sun's in-
come and revenues are affected by market supply and demand for Sun's products
and actions taken by competitors (including both pricing and expansion and re-
tirement of refinery capacity in response to market conditions), as well as
changes in industry-wide refining margins, market forces affecting the avail-
ability and pricing of oxygenates such as MTBE, changes in crude oil and other
raw material costs, and world and regional events that could significantly in-
crease volatility in the marketplace.
 
The ability to meet liquidity requirements, including the funding of the
Company's capital program from operations, is subject to changes in commodity
prices and crude oil supply that could be affected by factors beyond Sun's con-
trol, such as embargoes, the continued discovery and production of light sweet
crude oil, or military conflicts involving (or internal instability in) one or
more oil-producing countries. Other factors that could affect Sun's business
include the continued availability of debt and equity financing, changes in la-
bor relations, general economic conditions (including recessionary trends, in-
flation and interest and currency exchange rates), and civil, criminal, regula-
tory or administrative actions, claims or proceedings. Sun's operations could
also be affected by domestic and international political, legislative, regula-
tory and legal actions, such as restrictions on production, restrictions on im-
ports and exports, price controls, tax increases and retroactive tax claims,
expropriation of property and cancellation of contract rights. Sun is impacted
by laws pertaining to workers' health and safety, and current or amended state
and federal environmental and other similar regulations (including, particular-
ly, regulations dealing with gasoline composition and characteristics) or the
judicial interpretation of such regulations.
 
The factors identified above are believed to be important factors (but not nec-
essarily all of the important factors) that could cause actual results to dif-
fer materially from those expressed in any forward-looking statement made by
Sun. Unpredictable or unknown factors not discussed herein could also have ma-
terial adverse effects on forward-looking statements. All forward-looking
statements included in this Annual Report on Form 10-K are expressly qualified
in their entirety by the foregoing cautionary statements. The Company under-
takes no obligation to update publicly any forward-looking statement (or its
associated cautionary language) whether as a result of new information or fu-
ture events.

*Effective in the third quarter of 1995, Sun began paying quarterly dividends on
 preference stock at a rate of $.90 per share and reduced its quarterly common
 stock dividend from $.45 to $.25 per share. Each share of preference stock is
 represented by two depositary shares. Each depositary share accrues dividends
 quarterly at a rate of $.45 per share, or one-half the rate paid on preference
 stock.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                              Sun Company, Inc. and Subsidiaries

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
Sun Company, Inc. and all operations that are controlled (generally more than
50 percent owned) except those accounted for as investments in operations held
for sale and discontinued operations (collectively, "Sun" or the "Company") are
consolidated. Affiliated companies over which the Company has the ability to
exercise significant influence but that are not controlled (generally 20 to 50
percent owned) are accounted for by the equity method.
 
USE OF ESTIMATES
Certain amounts included in the accompanying consolidated financial statements
and related footnotes reflect the use of estimates based on assumptions made by
management. Actual amounts could differ from these estimates.
 
CASH EQUIVALENTS
Sun considers all highly liquid investments with a remaining maturity of three
months or less at the time of purchase to be cash equivalents. These cash
equivalents consist principally of time deposits and certificates of deposit.
 
INVENTORIES
Inventories are valued at the lower of cost or market. The cost of crude oil
and refined product inventories is determined using the last-in, first-out
method ("LIFO"). The cost of materials, supplies and other inventories is de-
termined using principally the average cost method.
 
DEPRECIATION AND RETIREMENTS
Plants and equipment are generally depreciated on a straight-line basis over
their estimated useful lives. Coal property acquisition costs and capitalized
development costs are depleted by the unit of production method based on proved
reserves. Gains and losses on the disposals of fixed assets are generally re-
flected in income.
 
ENVIRONMENTAL REMEDIATION
Sun accrues environmental remediation costs for work at identified sites where
an assessment has indicated that cleanup costs are probable and reasonably es-
timable. Such accruals are undiscounted and are based on currently available
information, estimated timing of remedial actions and related inflation assump-
tions, existing technology and presently enacted laws and regulations.
 
REFINERY MAINTENANCE SHUTDOWNS
Maintenance and repair costs in excess of $500 thousand incurred in connection
with major refinery maintenance shutdowns are capitalized when incurred and
then amortized over the period benefitted by the maintenance activities.
 
FOREIGN CURRENCY TRANSLATION
Prior to the divestment of Suncor Inc., the functional currency for Canadian
operations was the Canadian dollar. Foreign exchange gains and losses that re-
sulted from translating Suncor's balance sheet from Canadian dollars into U.S.
dollars were included as a separate component of shareholders' equity. The
functional currency for International Production operations was the U.S. dol-
lar.
 
DERIVATIVE INSTRUMENTS
Sun uses swaps, options, futures, forwards and other off-balance sheet commodi-
ty-based financial and nonfinancial derivative instruments to hedge its expo-
sure to crude oil, natural gas, refined product and electricity price volatili-
ty. Such contracts, which effectively meet the Company's risk reduction and
correlation criteria, are recorded using hedge accounting. Effectiveness is
measured based upon the high correlation between the gains and losses on the
derivative contracts and the corresponding offsetting changes in the market
value of the underlying items being hedged. Under hedge accounting, gains or
losses on derivative contracts (whether or not held until the underlying items
being hedged are recognized in income) are deferred and recognized in cost of
products sold and operating expenses in the same periods as the underlying
items being hedged. In the event a derivative contract were to become ineffec-
tive as a hedge or if an anticipated transaction being hedged were no longer
likely to occur, any related unrealized derivative gain or loss would be recog-
nized in income at such time. The cash flows from hedge contracts are included
in operating activities in the consolidated statements of cash flows. Sun does
not hold or issue derivative instruments for trading purposes.
 
STOCK-BASED COMPENSATION
The Company follows the method of accounting for employee stock compensation
plans prescribed by Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees" ("APB No. 25") (Note 15).

2. CHANGES IN BUSINESS
 
The following is a summary of Sun's significant changes in business during the
three-year period ended December 31, 1997:
 
DISCONTINUED OPERATIONS
On September 30, 1996, Sun completed the sale of its international oil and gas
production business for $278 million in cash. The sale of this business repre-
sents the completion of the Company's withdrawal from oil and gas exploration
and production activities. The Company withdrew from international exploration
activities in 1992 and divested its remaining 55-percent interest in Suncor
Inc., a Canadian integrated oil company, on June 8, 1995. Sun received $770
million from the sale of Suncor, after commissions and discounts, of which $635
million was received in June 1995 and $135 million was received in June 1996.
 
As a result of the sale of the international oil and gas production business,
it and the previously divested Canadian synthetic oil production and conven-
tional oil and gas exploration and production operations (collectively, "Cana-
dian Upstream Petroleum Operations") have been classified as discontinued oper-
ations in 1996 and 1995 up to their respective dates of divestment. The follow-
ing is a summary of income from discontinued operations:

Income from discontinued International Production Operations in 1996 includes a
$125 million gain on divestment of this business (comprised of a pretax gain of
$93 million and an income tax benefit of $32 million). Income from discontinued
Canadian Upstream Petroleum Operations in 1995 includes a $157 million gain on
divestment of Suncor (comprised of a pretax gain of $242 million and income tax
expense of $85 million).
 
Prior to their divestment, sales and other operating revenue from discontinued
International Production Operations totalled $187 and $236 million for 1996 and
1995, respectively, while sales and other operating revenue from discontinued
Canadian Upstream Petroleum Operations totalled $271 million for 1995.
 
INVESTMENTS IN OPERATIONS HELD FOR SALE
 
Real Estate Operations--Sun has been disposing of the assets of Radnor Corpora-
tion ("Radnor"), its wholly owned real estate development subsidiary, since Oc-
tober 1991 and subsequent to that date has divested approximately 95 percent of
Radnor's real estate portfolio. Radnor is accounted for as an investment held
for sale. Accordingly, pretax results from real estate operations have been in-
cluded as a single amount in other income in the accompanying consolidated
statements of operations (Note 4).
 
Radnor's assets and liabilities have been segregated in the consolidated bal-
ance sheets and separately reflected as an investment in operations held for
sale. Such amounts are detailed as follows:

Coal and Cokemaking Operations--In January 1993, Sun decided to sell its coal
and cokemaking operations. In connection with this decision, Sun sold its west-
ern U.S. coal operations during 1993 and certain of its eastern U.S. coal oper-
ations during 1994. Prior to June 30, 1995, Sun's coal and cokemaking opera-
tions had been accounted for as an investment held for sale. However, effective
June 30, 1995, the remaining coal and cokemaking business became one of the
Company's ongoing business units and is no longer held for sale. Accordingly,
the consolidated balance sheets as of December 31, 1997 and 1996 contain the
accounts of Sun's coal and cokemaking operations on a fully consolidated basis.
The accompanying consolidated statements of operations and cash flows reflect
coal and cokemaking operations on a fully consolidated basis after June 30,
1995 and as an operation held for sale prior to that date.

- ---------------------------------------------

 
During the first quarter of 1997, Sun established an accrual for approximately
320 involuntary employee terminations and related costs. The employee reduc-
tions are throughout the organization and include senior management, support
staff and operations personnel. As of December 31, 1997, the amount of actual
termination benefits paid and charged against the accrual totalled $22 million.
 
During the fourth quarter of 1996, Sun reconfigured the Philadelphia refinery
to process only sweet crude oil and to cease asphalt production. This
reconfiguration continues the integration of the Point Breeze and Girard Point
facilities at the Philadelphia, PA, refinery. In 1996, Sun also announced that
it would reconfigure the Puerto Rico refinery commencing in the first quarter
of 1997 to significantly reduce fuels production while fully maintaining the
volume and quality of lubricants production. In connection with these
reconfigurations, Sun recorded provisions to write off redundant and/or unprof-
itable processing units and established accruals for environmental remediation
activities, employee terminations and related costs. In addition, at December
31, 1996, Sun established accruals for estimated losses expected to be realized
with respect to an off-take agreement to purchase MTBE (Note 13) and for other
environmental remediation activities and recorded a provision to write down to
fair value certain assets in its refining and marketing business.
 
During 1995, Sun recorded a provision to write down to fair value certain as-
sets in the refining and marketing business and to establish accruals for em-
ployee terminations and related costs. The $50 million accrual for employee
terminations and related costs consisted of $38 million attributable to termi-
nation benefits and $12 million related to future rental payments for vacated
office space.
 
ACQUISITION OF KENDALL LUBRICANTS BUSINESS
On November 1, 1996, Sun acquired the Kendall lubricants blending, packaging
and marketing business for $74 million. The acquisition has been accounted for
as a purchase and, accordingly, the results of operations of this business have
been included in the consolidated statements of operations since the date of
acquisition. The purchase price has been allocated to the assets acquired based
on their relative fair market values (Note 17). The results of operations of
the Kendall lubricants business in 1996 and 1995 were not material in relation
to Sun's consolidated results of operations.
 
3. CHANGE IN ACCOUNTING PRINCIPLE
 
Effective January 1, 1995, Sun adopted the provisions of Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived As-
sets and for Long-Lived Assets to be Disposed Of." This statement requires com-
panies to write down to estimated fair value long-lived assets that are im-
paired. Certain of the write-downs recognized in 1995 are reflected as a cumu-
lative effect of a change in accounting principle in the consolidated statement
of operations and related to properties to be disposed of in the Company's
coal, real estate and refining and marketing operations. The following table
sets forth summary information concerning these write-downs:
 


                           Pretax  After-tax

- --------------------------------------------

                             $145        $87
============================================

*Primarily service stations and terminals.
 
The impaired coal assets were sold during 1996. The disposal of the Company's
remaining real estate portfolio and the refining and marketing assets held for
sale is expected to be substantially completed by the end of 1999. Other than
the cumulative effect, the results of operations during the 1995-97 period for
the properties to be disposed of were not significant.

6. EARNINGS PER SHARE
 
In 1997, Statement of Financial Accounting Standards No. 128, "Earnings Per
Share" ("SFAS No. 128") was issued which replaced the disclosure of earnings
per share ("EPS") on a primary and fully diluted basis with basic and diluted
EPS. Unlike primary EPS, basic EPS excludes any dilutive effect of stock incen-
tive awards. Diluted EPS is very similar to fully diluted EPS. All EPS amounts
in the accompanying consolidated statements of operations have been presented
in accordance with SFAS No. 128. The new standard had no impact on previously
reported full year 1996 and 1995 EPS amounts.
 
Basic EPS is computed by dividing earnings (losses) after deducting dividends
on preference stock (Note 14) by the weighted average number of common shares
outstanding. Diluted EPS generally is determined by dividing
 
                                                                              48

 
earnings (losses) by the weighted average number of shares outstanding after
giving effect to the assumed issuance of common stock under stock incentive
awards and the assumed redemption of preference shares for common stock utiliz-
ing a ratio of two shares of common stock for each outstanding preference
share. However, in 1996 and 1995, since both the assumed issuance of common
stock under stock incentive awards and the assumed redemption of preference
shares would not have been dilutive, diluted per share amounts are equal to ba-
sic per share amounts.
 
The following table sets forth the computation of basic and diluted EPS from
continuing operations for 1997:

The current replacement cost of all inventories valued at LIFO exceeded their
carrying value by $492 and $780 million at December 31, 1997 and 1996, respec-
tively. During 1996, Sun reduced certain inventory quantities which were valued
at lower LIFO costs prevailing in prior years. The effect of this reduction was
to decrease the 1996 net loss by $8 million.

Dividends received from affiliated companies amounted to $13, $15 and $11 mil-
lion in 1997, 1996 and 1995, respectively. Earnings employed in the business at
December 31, 1997 include $42 million of undistributed earnings of affiliated

10. CREDIT FACILITIES
 
The Company has a $500 million revolving credit agreement ("Agreement") with
commercial banks that provides access to short-term financing through September
2002. The Company can borrow directly from the participating banks under this
Agreement or use it to support commercial paper issued by Sun. The Agreement is
subject to commitment fees, the amounts of which are not material. Under the
terms of the Agreement, Sun is required, among other things, to maintain con-
solidated net worth of at least $1.0 billion. At December 31, 1997, the
Company's consolidated net worth was $1.5 billion. Sun also has access to
short-term financing under non-committed money market facilities. At December
31, 1997 and 1996, there were no amounts outstanding related to the above
short-term borrowing arrangements.

12. RETIREMENT BENEFIT PLANS
 
DEFINED BENEFIT PENSION PLANS
Sun has noncontributory defined benefit pension plans which provide retirement
benefits for the majority of its employees. Plan benefits are generally based
on years of service, age at retirement and employees' compensation. For Sun's
principal defined benefit pension plan, the benefit for employees hired prior
to January 1, 1987 is determined based on either final or total career average
compensation, whichever produces the greater benefit. For employees hired on or
after January 1, 1987, the benefit is generally determined based on total ca-
reer average compensation. It is Sun's policy to fund defined benefit pension
contributions in accordance with the requirements of the Internal Revenue Code.
Pension expense consisted of the following components:

 *Estimated returns on assets are used in determining net periodic pension cost.
  Differences between estimated and actual returns are included in net
  amortization and deferral. Net amortization and deferral also includes
  amortization of the unrecognized net asset or obligation at January 1, 1986
  and amortization of the unrecognized prior service cost and unrecognized net
  gain or loss as of the beginning of each year.
**Excludes $(2) and $1 million curtailment gains (losses) recognized in
  connection with the employee termination programs implemented during 1997 and
  1995, respectively (Note 2).

 *Plan assets consist principally of commingled trust funds, marketable equity
  securities, corporate and government debt securities and real estate. Less
  than 1 percent of plan assets was invested in Company common and preference
  stock at both December 31, 1997 and 1996.
**An equivalent intangible asset is included in deferred charges and other as-
  sets in the consolidated balance sheets.
 
                                                                              50

 
 
As of December 31, 1997 and 1996, the projected benefit obligations were deter-
mined using weighted average assumed discount rates of 7.0 and 7.5 percent, re-
spectively, and a rate of compensation increase of 4.0 percent. The weighted
average expected long-term rate of return on plan assets was 9.0 percent in
both 1997 and 1996. All of these rates are subject to change in the future as
economic conditions change.
 
DEFINED CONTRIBUTION PENSION PLANS
Sun has defined contribution pension plans which provide retirement benefits
for most of its employees. Sun's contributions, which are principally based on
a percentage of employees' annual base compensation and are charged against in-
come as incurred, amounted to $17, $18 and $18 million in 1997, 1996 and 1995,
respectively.
 
Sun's principal defined contribution plan is the Sun Company, Inc. Capital Ac-
cumulation Plan ("SunCAP"). Sun matches 100 percent of employee contributions
to the plan up to 5 percent of an employee's base compensation. SunCAP is a
combined profit sharing and employee stock ownership plan which contains a pro-
vision designed to permit SunCAP, only upon approval by the Company's Board of
Directors, to borrow in order to purchase shares of Company common stock. As of
December 31, 1997, no such borrowings had been approved.
 
POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS
Sun has plans which provide health care and life insurance benefits for sub-
stantially all retirees. The plans are unfunded and the costs are shared by Sun
and its retirees. Postretirement benefits expense consisted of the following
components:
 



(Millions of Dollars)      1997       1996      1995

  (Note 2).

The following table sets forth the funded status of the plans and amounts rec-
ognized in the balance sheets at:

As of December 31, 1997 and 1996, the APBO was determined using weighted aver-
age assumed discount rates of 7.0 and 7.5 percent, respectively. The health
care cost trend assumptions used at December 31, 1997 and 1996 were 7.0 and 7.3
percent, respectively, which are assumed to decline gradually to 5.5 percent in
2001 and to remain at that level thereafter. All of these rates are subject to
change in the future as economic conditions change. An increase in the assumed
health care cost trend rate by one percentage point in each year would have in-
creased the APBO by $8 million at December 31, 1997 and would have increased
the service and interest components of postretirement benefits expense in the
aggregate by $1 million for each of the three years in the period ended Decem-
ber 31, 1997.
 
13. COMMITMENTS AND CONTINGENT LIABILITIES
 
Sun, as lessee, has noncancelable operating leases for marine transportation
time charters and for service stations, office space and other property and
equipment. Total rental expense for such leases for the years 1997, 1996 and
1995 amounted to $107, $97 and $102 million, respectively. Approximately 8 per-
cent of total rental expense was recovered through related sublease rental in-
come during 1997. Under contracts existing as of December 31, 1997, future min-
imum annual rentals applicable to noncancelable operating leases are as follows
(in millions of dollars):

A wholly owned subsidiary of the Company is a one-third partner in Belvieu En-
vironmental Fuels ("BEF"), a joint venture formed for the purpose of construct-
ing,
 
51

 
owning and operating a $225 million methyl tertiary butyl ether ("MTBE") pro-
duction facility in Mont Belvieu, Texas. The facility was completed in 1995.
 
In order to obtain a secure supply of oxygenates for the manufacture of refor-
mulated gasoline, Sun entered into an off-take agreement with BEF whereby Sun
agreed to purchase all of the MTBE production from the plant. For the first
14,000 barrels daily of production, Sun agreed to pay BEF prices through May
1997 based on the market value of MTBE feedstocks (methanol and butane) plus a
fixed amount per gallon (the "formula price"), and thereafter through May 2000
based on the then-existing MTBE prices per gallon in the contract market (the
"contract market price"). However, the price to be paid by Sun for the first
12,600 barrels daily of MTBE production through May 2000, at a minimum, will
equal the sum of BEF's annual raw material and operating costs associated with
this production plus BEF's debt service payments (collectively, the "minimum
price") if the minimum price per gallon exceeds the applicable formula or con-
tract market price. After May 2000, Sun and BEF will negotiate a new price for
the last four years of the agreement based upon the market conditions existing
at that time.
 
Sun's total MTBE purchases under this agreement were $235, $214 and $150 mil-
lion during 1997, 1996 and 1995, respectively. Such amounts were based upon the
formula price through May 1997 and the minimum price for the remainder of 1997.
The formula prices paid by Sun during most of 1996 were believed to have ap-
proximated prices of other MTBE long-term sales agreements in the marketplace.
However, management believes that the contract market changed in the latter
part of 1996 as feedstock-plus-fixed-priced contracts expired and were replaced
by spot-market-price-based contracts, which have been more favorable to the
purchaser. Management also believes that the spot market for MTBE had developed
by the latter part of 1996. During the fourth quarter of 1996, spot market
prices for MTBE were less than the prices paid by Sun under the off-take agree-
ment with BEF. At that time, the Company expected this adverse relationship to
continue into the future. Accordingly, a $130 million accrual ($85 million af-
ter tax) was established at December 31, 1996 for the estimated losses expected
to be realized with respect to this agreement. During 1997, actual MTBE pur-
chase costs in excess of market prices totalling $65 million were charged
against the accrual.
 
Sun is contingently liable under various arrangements which guarantee debt of
affiliated companies and others aggregating approximately $27 million at
December 31, 1997 and maturing at various dates through 2014.
 
Sun is subject to numerous federal, state and local laws regulating the dis-
charge of materials into, or otherwise relating to the protection of, the envi-
ronment. These laws result in liabilities and loss contingencies for
remediation at Sun's facilities and at third-party or formerly-owned sites. The
accrued liability for environmental remediation is classified in the consoli-
dated balance sheets as follows:
 


                                 December 31
                                -------------
(Millions of Dollars)           1997     1996

- ---------------------------------------------
                                $204     $227
- ---------------------------------------------

 
Pretax charges against income for environmental remediation totalled $6, $56
and $12 million in 1997, 1996 and 1995, respectively. The high level of expense
in 1996 was largely attributable to accruals for remediation activities associ-
ated with the reconfigurations of the Philadelphia and Puerto Rico refineries
and to increased accruals at service station sites (Note 2). The 1996 service
station accruals were determined utilizing recent regulatory changes which in-
corporate a risk-based methodology and clarify previously uncertain remediation
requirements. Claims for recovery of environmental liabilities that are proba-
ble of realization totalled $3 million at December 31, 1997 and are included in
deferred charges and other assets in the consolidated balance sheets.
 
On October 4, 1996, Sun filed a complaint in Los Angeles County Superior Court,
Jalisco Corporation, Inc., et al. v. Argonaut Insurance Company, et al. (Case
No. BC 158441), naming more than 45 insurance companies as defendants and seek-
ing recovery under numerous insurance policies for certain environmental expen-
ditures of Sun, including its predecessor companies and subsidiaries, arising
from the ownership and operation of its business and properties. The Company
cannot quantify the ultimate outcome of this litigation, which may be protract-
ed.
 
Total future costs for environmental remediation activities will depend upon,
among other things, the identification of any additional sites, the determina-
tion of the extent of contamination at each site, the timing and nature of re-
quired remedial actions, the technology available and needed to meet the vari-
ous existing legal requirements, the nature and extent of future environmental
laws, inflation rates and the determination of Sun's liability at multi-party
sites, if any, in light of the number, participation levels and financial via-
bility of other parties.
 
Many other legal and administrative proceedings are pending against Sun. The
ultimate outcome of these proceedings and the matters discussed above cannot be
as-
 
                                                                              52

 
certained at this time; however, it is reasonably possible that some of them
could be resolved unfavorably to Sun. Management believes that any expenditures
attributable to these matters will be incurred over an extended period of time
and will be funded from Sun's net cash flows from operating activities. Al-
though the ultimate impact of these matters could have a significant impact on
results of operations for any one year, management of Sun believes that any ad-
ditional liabilities which may arise pertaining to such matters would not be
material in relation to the consolidated financial position of Sun at December
31, 1997.
 
14. SHAREHOLDERS' EQUITY
 
Each share of Company common stock is entitled to one full vote. The $10 mil-
lion of outstanding 6 3/4 percent debentures are convertible into shares of
common stock of the Company at any time prior to maturity at a conversion price
of $40.81 per share and are redeemable at the option of the Company. At Decem-
ber 31, 1997, there were 242,981 shares of common stock reserved for this po-
tential conversion (Note 11).
 
On August 3, 1995, the Company issued 25,000,000 "depositary shares" in ex-
change for an equal number of shares of Company common stock in a tax-free
transaction. Each depositary share represents ownership of one-half share of
the Company's Series A cumulative preference stock. The Company also reduced
the quarterly dividend paid on common stock from $.45 per share ($1.80 per
year) to $.25 per share ($1.00 per year). In addition, the Company repurchased
6,400,000 shares of its common stock on August 9, 1995 through a tender offer
for $192 million and an additional 6,774,500 shares of common stock and 885,700
depositary shares during the 1995-97 period on the open market for $250 mil-
lion. At December 31, 1997, the Company had a remaining authorization from its
Board of Directors ("Board") to purchase up to $150 million of stock in the
open market or through privately negotiated transactions from time to time de-
pending on prevailing market conditions.
 
Each owner of a depositary share is entitled, proportionately, to all the
rights, preferences and privileges of the preference stock represented thereby.
Dividends on the preference stock are cumulative and accrue at a rate of $3.60
per year. The preference stock ranks prior to common stock with respect to div-
idend rights and rights upon liquidation, dissolution and winding up of the
Company. Each share of preference stock has a liquidation preference equal to
$60.00, which is twice the fair market value of a depositary share at its date
of issuance, plus accrued and unpaid dividends. The holders of preference stock
vote together with the holders of common stock as a single class, and are enti-
tled to one full vote for each share of preference stock owned.
 
The outstanding shares of preference stock are redeemable at any time by the
Company, in whole or in part, for common stock at a value which initially
equaled $84.80 per share of preference stock at June 12, 1995 and is declining
ratably to $80.00 per share of preference stock at June 11, 1998. As of Febru-
ary 12, 1998, this call price was $80.53 per share of preference stock. After
June 11, 1998, the Company can redeem each outstanding share of preference
stock for two shares of common stock, subject to adjustment in certain events.
The redemption value also includes a cash amount equal to all proportionate ac-
crued but unpaid dividends. If Sun were to do a partial redemption of prefer-
ence stock, it would be done on a pro rata basis. The Company currently intends
to redeem all of the outstanding preference stock (and thereby the depositary
shares) no later than June 12, 1998.
 
The Company's Articles of Incorporation authorize the issuance of up to
2,500,000 shares of additional classes of preference stock without par value,
subject to approval by the Board. The Board also has authority to fix the num-
ber, designation, rights, preferences and limitations of these shares, subject
to applicable laws and the provisions of the Articles of Incorporation.
 
On February 1, 1996, the Company adopted a shareholder rights plan and desig-
nated 1,743,019 shares of the remaining 2,500,000 authorized cumulative prefer-
ence stock as Series B participating cumulative preference stock. Pursuant to
the plan, the Company declared a dividend of one stock purchase right ("Right")
for each share of common stock and two Rights for each share of Series A cumu-
lative preference stock outstanding on February 12, 1996. A Right will be
granted for each share of common stock issued after such date and prior to the
expiration date of the rights plan. Generally, the Rights become exercisable a
specified period after a party acquires 15 percent or more of the aggregate
outstanding common stock and Series A cumulative preference stock (collective-
ly, "Voting Stock") or announces a tender offer for 15 percent or more of the
Voting Stock. Each Right initially entitles a holder to purchase one one-
hundredth of a share of the Series B participating cumulative preference stock
for $100. After a party has acquired 15 percent or more of the Voting Stock,
each Right will entitle a holder to pay $100 for the number of shares of Com-
pany common stock (or in certain situations, common stock of the acquiring par-
ty) having a then current market value of $200. Alternatively, the Company has
the option to exchange one share of Company common stock for each Right at any
time after a party has acquired at least 15 percent but less than 50 percent of
the Voting Stock. The Company may redeem each Right for $.01 per Right at any
time until the end of a specified period after a party has acquired 15 percent
 
53

 
or more of the Voting Stock. In general, none of the benefits of the Rights
will be available to a holder of 15 percent or more of the Voting Stock. The
Rights will expire on February 12, 2006, unless earlier exchanged or redeemed.
 
In December 1992, the Board approved the adoption of the Employee Option Plan
("EOP") which provides for the award of stock options to all employees (other
than executives) of the Company and certain subsidiaries. The awards have a
ten-year term, are not exercisable until two years after the date of grant and
permit optionees to purchase Company common stock at the fair market value on
the date of grant. Two million shares of Company common stock are authorized
for issuance under the EOP. In 1994 and 1993, stock option awards totalling
241,895 and 1,721,385, respectively, were made to eligible employees.
 
15. MANAGEMENT INCENTIVE PLANS
 
Sun's principal management incentive plans are the Executive Incentive Plan
("EIP") and the Long-Term Performance Enhancement Plan ("LTPEP"). The EIP pro-
vides for the payment of annual cash incentive awards while the LTPEP, which
succeeded the Executive Long-Term Stock Investment Plan in May 1997, provides
for the award of stock options, common stock units and related rights to offi-
cers and other key employees of Sun. The option awards under LTPEP have a ten-
year term, are not exercisable until two years after the date of grant and per-
mit optionees to purchase Company common stock at the fair market value on the
date of grant. No awards may be granted under LTPEP after December 31, 2001,
unless the Board extends this date to a date no later than December 31, 2006.
Aggregate charges against income for Sun's principal management incentive plans
for 1997 and 1995 were $17 and $4 million, respectively. There were no charges
against income for Sun's principal management incentive plans in 1996.
 
The following table summarizes information with respect to common stock option
awards under the EOP (Note 14) and Sun's management incentive plans:

 of a restriction period or upon attainment of predetermined performance tar-
 gets. In addition, 1997 includes 144,116 options cancelled due to the exercise
 of related alternate appreciation rights which resulted in the issuance of

The Company follows the method of accounting for employee stock compensation
plans prescribed by APB No. 25. In accordance with APB No. 25, the Company has
not recognized compensation expense for stock options because the exercise
price of the options equals the market price of the underlying stock on the
date of grant, which is the measurement date. Had the alternative method of ac-
counting for employee stock compensation plans prescribed by Statement of Fi-
nancial Accounting Standards No. 123, "Accounting for Stock-Based Compensation"
been followed, the pro forma impact on Sun's net income (loss) and net income
(loss) per share of common stock on a diluted basis would have been as follows:
 


(Millions of Dollars, Except Per Share Amounts)      1997     1996      1995
- ----------------------------------------------------------------------------

Net income (loss) per share:

The fair values per options granted during 1997, 1996 and 1995 were estimated
to be $10.59, $5.41 and $6.74, respectively, using the Black-Scholes option
pricing model based on the following weighted-average assumptions:

16. FINANCIAL INSTRUMENTS
 
The estimated fair value of financial instruments has been determined based on
the Company's assessment of available market information and appropriate valua-
tion methodologies. However, these estimates may not necessarily be indicative
of the amounts that the Company could realize in a current market exchange.
 
Sun's current assets (other than inventories and deferred income taxes) and
current liabilities are financial instruments. The estimated fair value of
these financial instruments approximates their carrying amounts. At December
31, 1997 and 1996, the estimated fair value of Sun's long-term debt amounted to
$918 and $903 million, respectively, compared to carrying amounts of $824 and
$835 million, respectively. Long-term debt which is publicly traded was valued
based on quoted market prices while the fair value of other debt issues was es-
timated by management based upon current interest rates available to Sun at the
respective balance sheet dates for similar issues.
 
The Company guarantees the debt of affiliated companies and others (Note 13).
Due to the complexity of these guarantees and the absence of any market for
these financial instruments, the Company does not believe it is practicable to
estimate their fair value.
 
Sun uses a variety of off-balance sheet commodity-based financial and nonfinan-
cial derivative instruments for hedging purposes. Sun is at risk for possible
changes in the market value for these derivative instruments. However, it is
anticipated that such risk would be mitigated by price changes in the under-
lying hedged transactions. In addition, Sun is exposed to credit risk in the
event of nonperformance by counterparties. Management believes this risk is
negligible as its counterparties are either regulated by exchanges or are major
international financial institutions with high credit ratings. Market and
credit risks associated with all of Sun's derivative contracts are reviewed
regularly by management.
 
The significant derivative instruments outstanding are swaps, price collars and
other option contracts which are used to hedge the unfavorable impact of sig-
nificant increases in crude oil prices and to lock in what Sun considers to be
acceptable wholesale margins for various refined products. At December 31,
1997, these financial instruments were used to hedge approximately 4 million
barrels (2 percent) of Sun's expected 1998 crude oil purchases and to lock in
margins for approximately
 
55

 
6 million barrels (2 percent) of its expected 1998 wholesale fuel sales. These
swap and option contracts vary in duration but do not extend beyond 1998. Al-
though these contracts are intended to limit the Company's exposure to rising
crude oil prices and/or declining margins, they could limit the Company's par-
ticipation in falling crude oil prices and/or rising margins. In addition,
among other derivative uses, Sun uses futures and forward contracts to achieve
ratable pricing of its crude oil purchases and refined product sales and swap
and option contracts to lock in a portion of its electricity and natural gas
refinery fuel costs.
 
The following table sets forth summary information concerning Sun's financial
and nonfinancial derivative instruments at December 31, 1997:

17. SUPPLEMENTAL CASH FLOW INFORMATION
 
During 1996, Sun acquired the Kendall lubricants business (Note 2). The follow-
ing is a summary of the effects of this transaction on Sun's consolidated fi-
nancial position as of the acquisition date:
 


(Millions of Dollars)

- ------------------------------------------
Decrease in cash and cash equivalents  $74

In 1995, Sun transferred an interest in its cokemaking operations in exchange
for $95 million in cash. The transferee is entitled to a preferential return
from the cash flows of the cokemaking operation until certain cumulative return
targets have been met. Sun did not recognize a gain or loss on this transac-
tion. The transaction has not had a significant impact on Sun's results of
operations.
 
Cash payments for income taxes were $26, $7 and $41 million in 1997, 1996 and
1995, respectively. Cash payments for interest, net of amounts capitalized,
were $75, $74 and $95 million in 1997, 1996 and 1995, respectively.
 
18. BUSINESS SEGMENT INFORMATION
 
Sun is principally a petroleum refiner and marketer with interests in coal min-
ing and cokemaking. Sun also has an investment in real estate operations held
for sale.
 
Sun's petroleum refining and marketing operations include the refining of crude
oil and its derivatives; the marketing of a full range of petroleum products,
including fuels, lubricants and petrochemicals; and the transportation of crude
oil and refined products. Such operations are currently conducted principally
in the eastern half of the United States. Sun's coal mining and cokemaking op-
erations are conducted in Virginia, Indiana and Kentucky.
 
Sun completed the sale of its International Production business on September
30, 1996 and divested its remaining interest in Suncor, a Canadian integrated
oil company, on June 8, 1995. As a result, Sun's international oil and gas pro-
duction and Canadian upstream petroleum operations are presented as discontin-
ued operations in 1996 and 1995 up to their respective divestment dates.

Income tax amounts give effect to tax credits in each of the designated indus-
try segments. Overhead expenses that can be identified with Sun's operations in
the designated industry segments have been included as deductions in determin-
ing operating profits and profit contributions. Net financing expenses consist
of interest cost, debt and other financing expenses less interest income and
interest capitalized. Identifiable assets are those assets that are utilized
within a specific segment.
 
19. SUBSEQUENT EVENT
 
In early 1998, Sun transferred an interest in its cokemaking operations in East
Chicago, IN, to a third party in exchange for $200 million in cash. The trans-
feree is entitled to a preferential return from the cash flows of this
cokemaking operation until certain cumulative return targets have been met. Sun
did not recognize a gain or loss on this transaction.
 
                                                                              58

REPORT OF MANAGEMENT
 
To the Shareholders of Sun Company, Inc.
 
 The accompanying consolidated financial statements of Sun Company, Inc. and
its subsidiaries ("Sun") and the related information are the responsibility of
management. The financial statements, which include amounts based on informed
estimates and judgments, were prepared using generally accepted accounting
principles deemed appropriate in the circumstances. Management believes that
these financial statements present fairly, in all material respects, Sun's fi-
nancial position, results of operations and cash flows. Other financial infor-
mation presented in this Annual Report is consistent with that in the financial
statements.
 To fulfill its responsibility for the financial statements, Sun maintains a
system of internal controls which in management's opinion provides reasonable
assurance of achieving the objectives of internal control. These objectives in-
clude safeguarding of assets from loss through unauthorized use or disposition
and maintaining reliable records permitting the preparation of financial state-
ments and accountability for assets. The system of internal controls is subject
to ongoing evaluation of its continuing effectiveness.
 Sun's independent auditors, Ernst & Young LLP, have expressed an opinion on
the fairness of management's 1997 and 1996 financial statements by conducting
their audits in accordance with generally accepted auditing standards and issu-
ing the report presented on this page.
 The Audit Committee of the Board of Directors is comprised of directors who
are not employees of Sun and meets a minimum of four times annually. It assists
the Board of Directors in discharging its duties relating to accounting and re-
porting practices and internal controls, and it assesses the performance and
recommends the appointment of independent auditors. Both the independent audi-
tors and Sun's internal auditors have unrestricted access to the Committee to
discuss audit findings and other financial matters.

REPORT OF INDEPENDENT AUDITORS
 
To the Shareholders and Board of Directors, Sun Company, Inc.
 
 We have audited the accompanying consolidated balance sheets of Sun Company,
Inc. and subsidiaries as of December 31, 1997 and 1996, and the related consol-
idated statements of operations, changes in shareholders' equity and cash flows
for the years then ended. 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. The consolidated statements of opera-
tions, changes in shareholders' equity and cash flows for the year ended Decem-
ber 31, 1995 were audited by other auditors whose report dated February 13,
1996 (except for the restatement for discontinued operations as described in
Note 2 for which the date is February 13, 1997) expressed an unqualified opin-
ion on those financial statements and included an explanatory paragraph that
disclosed the change in the Company's method of accounting for the impairment
of long-lived assets in 1995, discussed in Note 3 to these financial state-
ments.
 We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of mate-
rial misstatement. An audit includes examining, on a test basis, evidence sup-
porting 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 pre-
sentation. We believe that our audits provide a reasonable basis for our opin-
ion.
 In our opinion, the 1997 and 1996 financial statements referred to above pres-
ent fairly, in all material respects, the consolidated financial position of
Sun Company, Inc. and subsidiaries at December 31, 1997 and 1996 and the con-
solidated results of their operations and their cash flows for the years then
ended, in conformity with generally accepted accounting principles.

 6, 1997 of an 85.0 thousand barrels-per-day crude unit in connection with a
 project to reconfigure the Puerto Rico refinery to process reduced crude oil
 instead of conventional crude oil. This reconfiguration has resulted in a
 significant reduction in fuels production while fully maintaining the
 lubricants manufacturing capabilities of the facility. Effective January 1,
 1998, Sun's crude processing capacity increased 5 thousand barrels per day due
 to an increase in capacity at the Toledo refinery.

  *Gross profit equals sales and other operating revenue less cost of products
   sold and operating expenses; depreciation, depletion and amortization; and
   consumer excise, payroll and other applicable taxes.
 **Includes a $21 million after-tax provision for employee terminations and re-
   lated costs.
***Includes a $53 million after-tax provision for write-down of assets and
   other matters.
  +Includes a $201 million after-tax provision for write-down of assets and
   other matters and an $8 million after-tax profit due to the reduction in
   certain in-ventory quantities which were valued at lower LIFO costs
   prevailing in prior years.
 ++Includes a $125 million after-tax gain on the sale of the International Pro-
   duction business.
+++For the first and fourth quarters of 1997 and the four quarters of 1996, the
   diluted per share amounts are equal to the basic per share amounts since both
   the assumed issuance of common stock under stock incentive awards and the as-
   sumed redemption of preference shares would not have been dilutive during
   those periods. The basic income per share from continuing operations for the
   third quarter of 1997 and the loss per share from continuing operations and
   net income per share on a diluted basis for the third quarter of 1996 were
   previously reported on Securities and Exchange Commission Form 10-Q as $1.38,
   $(.11) and $1.19, respectively. The changes are due to the presentation of
   earnings per share amounts in accordance with Statement of Financial Account-
   ing Standards No. 128, "Earnings Per Share," which was adopted in the fourth
   quarter of 1997.
  #The Company's common stock is principally traded on the New York Stock Ex-
   change, Inc. under the symbol "SUN." The Company had approximately 35,200
   holders of record of common stock as of January 30, 1998.
