PART I

ITEM 1. BUSINESS

Description of the Business

Southern Indiana Gas and Electric Company (the Company or SIGECO), an Indiana
corporation, provides electric generation, transmission, and distribution
services to 8 counties in southwestern Indiana, including counties surrounding
Evansville, and participates in the wholesale power market. The Company also
provides natural gas distribution and transportation services to 10 counties in
southwestern Indiana, including counties surrounding Evansville. SIGECO is a
direct, wholly owned subsidiary of Vectren Utility Holdings, Inc. (VUHI). VUHI
is a direct, wholly owned subsidiary of Vectren Corporation (Vectren). SIGECO
generally does business as Vectren Energy Delivery of Indiana, Inc.

Vectren, an Indiana corporation, is an energy and applied technology holding
company headquartered in Evansville, Indiana. Vectren was organized on June 10,
1999, solely for the purpose of effecting the merger of Indiana Energy, Inc.
(Indiana Energy) and SIGCORP, Inc. (SIGCORP). On March 31, 2000, the merger of
Indiana Energy with SIGCORP and into Vectren was consummated with a tax-free
exchange of shares and has been accounted for as a pooling-of-interests in
accordance with APB Opinion No. 16 "Business Combinations" (APB 16).

Vectren's wholly owned subsidiary, VUHI, serves as the intermediate holding
company for its three operating public utilities, Indiana Gas Company, Inc.
(Indiana Gas), formerly a wholly owned subsidiary of Indiana Energy, Inc.
(Indiana Energy), SIGECO, formerly a wholly owned subsidiary of SIGCORP, and the
Ohio operations, a utility jointly owned by Indiana Gas and Vectren Energy
Delivery of Ohio, Inc. (VEDO). Both Vectren and VUHI are exempt from
registration pursuant to Section 3(a)(1) and 3(c) of the Public Utility Holding
Company Act of 1935.

The narrative description of the business, competition and personnel sections
were intentionally omitted. See the table of contents of this Annual Report on
Form 10-K for explanation.

ITEM 2. PROPERTIES

Electric Utility Services

SIGECO's installed generating capacity as of December 31, 2003, was rated at
1,351 MW. SIGECO's coal-fired generating facilities are: the Brown Station with
500 MW of capacity, located in Posey County approximately eight miles east of
Mt. Vernon, Indiana; the Culley Station with 406 MW of capacity, and Warrick
Unit 4 with 150 MW of capacity. Both the Culley and Warrick Stations are located
in Warrick County near Yankeetown, Indiana. SIGECO's gas-fired turbine peaking
units are: the 80 MW Brown 3 Gas Turbine located at the Brown Station; two

MW); two Northeast Gas Turbines located northeast of Evansville in Vanderburgh
County, Indiana with a combined capacity of 20 MW; and a new 80 MW turbine also
located at the Brown station (Brown Unit 4) placed into service in 2002. The
Brown Unit 3 and Broadway Avenue Unit 2 turbines are also equipped to burn oil.
Total capacity of SIGECO's six gas turbines is 295 MW, and they are generally
used only for reserve, peaking, or emergency purposes due to the higher per unit
cost of generation.

SIGECO's transmission system consists of 830 circuit miles of 138,000 and 69,000
volt lines. The transmission system also includes 27 substations with an
installed capacity of 4,235.9 megavolt amperes (Mva). The electric distribution
system includes 3,224 pole miles of lower voltage overhead lines and 289 trench
miles of conduit containing 1,622 miles of underground distribution cable. The
distribution system also includes 92 distribution substations with an installed
capacity of 1,901.7 Mva and 51,417 distribution transformers with an installed
capacity of 2,368.6 Mva.

SIGECO owns utility property outside of Indiana approximating eight miles of
138,000 volt electric transmission line which is located in Kentucky and which
interconnects with Louisville Gas and Electric Company's transmission system at
Cloverport, Kentucky.

Gas Utility Services

SIGECO owns and operates three underground gas storage fields located in Indiana
covering 6,070 acres of land with an estimated ready delivery from storage
capability of 6.3 BCF of gas with maximum peak day delivery capabilities of

ITEM 6. SELECTED FINANCIAL DATA

Intentionally omitted. See the table of contents of this Annual Report on Form

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION

Pursuant to General Instructions I(2)(a) of Form 10-K, the following analysis of
the results of operations is presented in lieu of Management's Discussion and
Analysis of Financial Condition and Results of Operations. The following
discussion and analysis should be read in conjunction with the financial
statements and notes thereto.

Executive Summary of Results of Operations

In 2003, net income applicable to common shareholder was $48.8 million, a
decrease of $10.5 million when compared to 2002. The decrease in 2003 compared
to 2002 was primarily driven by weather, a slowly recovering economy, and
increased operating expenses, partially offset by increased wholesale power
margins and retail electric rate recovery related to NOx compliance expenditures
and related operating expenses.

In 2002, net income applicable to common shareholder was $59.3 million, an
increase of $18.6 million when compared to 2001. The year ended December 31,
2001, included nonrecurring merger, integration, and restructuring costs and
other nonrecurring items totaling $4.0 million after tax. In addition to the
nonrecurring 2001 items, the increase reflected improved margins and lower
operating costs. These resulted from favorable weather and a return to lower gas
prices and the related reduction in costs incurred in 2001.

The Company generates revenue primarily from the delivery of electric service
and natural gas service to its customers. The primary source of cash flow
results from the collection of customer bills and the payment for goods and
services procured for the delivery of electric and gas services. Results are
impacted by weather patterns in its service territory and general economic
conditions both in its service territory as well as nationally.

The Company has in place a disclosure committee that consists of senior
management as well as financial management. The committee is actively involved
in the preparation and review of the Company's SEC filings.

Nonrecurring Items in 2001

Merger & Integration Costs

Merger and integration related costs incurred during 2001 totaled $0.6 million
($0.4 million after tax). These costs relate primarily to transaction costs,
severance, and other merger and acquisition integration activities. The
integration activities experienced by the Company included such things as
information system consolidation, process review and definition, organization
design and consolidation, and knowledge sharing. Merger and integration
activities resulting from the 2000 merger forming Vectren were completed in
2001.

Restructuring Costs

As part of continued cost saving efforts, in June 2001, the Company's management
and board of directors approved a plan to restructure, primarily, its regulated
operations. The restructuring plan included the elimination of certain
administrative and supervisory positions in its utility operations and corporate
office. Charges of $4.3 million were expensed in June 2001 as a direct result of
the restructuring plan. Additional charges of $1.5 million were incurred during
the remainder of 2001 primarily for consulting fees and employee relocation
costs. In total, the Company incurred restructuring charges of $5.8 million
($3.6 million after tax) in 2001. These charges were comprised of $4.4 million
for employee severance, related benefits and other employee related costs and
$1.4 million for consulting and other fees. The restructuring program was
completed during 2001, except for the departure of certain employees impacted by
the restructuring which occurred during 2002.

Cumulative Effect of Change in Accounting Principle

Resulting from the adoption of SFAS 133, certain contracts in the power
marketing operations that are periodically settled net were required to be
recorded at market value. Previously, the Company accounted for these contracts
on settlement. The cumulative impact of the adoption of SFAS 133 resulting from
marking these contracts to market on January 1, 2001, was an earnings gain of
approximately $1.8 million ($1.1 million after tax) recorded as a cumulative
effect of change in accounting principle in the Statements of Income.

Loss on extinguishment of preferred stock

In September 2001, the Company notified holders of its 4.80%, 4.75%, and 6.50%
preferred stock of its intention to redeem the shares. The 4.80% preferred stock
was redeemed at $110.00 per share, plus $1.35 per share in accrued and unpaid
dividends. Prior to the redemption, there were 85,519 shares outstanding. The
4.75% preferred stock was redeemed at $101.00 per share, plus $0.97 per share in
accrued and unpaid dividends. Prior to the redemption, there were 3,000 shares
outstanding. The 6.50% preferred stock was redeemed at $104.23 per share, plus
$0.73 per share in accrued and unpaid dividends. Prior to the redemption, there
were 75,000 shares outstanding. The total redemption price was $17.7 million and
the loss on redemption totaled $1.2 million.

Significant Fluctuations

Operating Margin

Margin generated from the sale of electricity and natural gas to residential and
commercial customers is seasonal and impacted by weather patterns in its service
territory. Margin generated from sales to industrial and other contract
customers is impacted by overall economic conditions. In general, operating
margin is not sensitive to variations in fuel or gas costs. It is, however,
impacted by the collection of state mandated taxes which fluctuate with gas
costs and also some level of fluctuation in volumes sold. Electric generating
asset optimization activities are primarily affected by market conditions, the
level of excess generating capacity, and electric transmission availability.
Following is a discussion and analysis of margin generated from regulated
utility operations.

Electric Utility Margin

Electric Utility margin by revenue type follows:

- ----------------------------------------------------------------------------
Total electric utility margin $ 233,045 $ 230,230 $ 219,904
============================================================================

Retail & Firm Wholesale Margin
For the year ended December 31, 2003, margin from serving native load and firm
wholesale customers was $214.8 million, a decrease of $2.7 million when compared
to 2002. It is estimated that summer weather 19% cooler than normal and 34%
cooler than last year caused an $8 million decrease in residential and
commercial margin. The estimated effect of weather was partially offset by a
$7.1 million increase in retail electric rates related to recovery of NOx
compliance expenditures and related operating expenses. A slowly recovering
economy continued to negatively impact industrial sales which decreased $1.3
million compared to 2002. As a result primarily of the mild weather and slow
economic conditions, retail and firm wholesale volumes sold decreased 5% to 5.90
GWh in 2003 compared to 6.19 GWh in 2002. Volumes sold in 2001 were 5.82 GWh.
The current year decrease in native load and firm wholesale margin has been
offset by increased margin from asset optimization activities as more fully
described below.

For the year ended December 31, 2002, margin from serving native load and firm
wholesale customers increased $16.7 million or 8%, when compared to 2001. The
increase results primarily from the effect on residential and commercial sales
of cooling weather considerably warmer than the prior year. Weather in 2002 was
27% warmer than 2001 and 23% warmer than normal. In addition to weather, 2002
was positively affected by increased industrial and other wholesale volumes and
rate recovery related to NOx compliance expenditures as the expenditures are
made pursuant to a rate recovery rider approved by the IURC in August 2001. As a
result of warmer weather and increased volumes sold, native load and firm
wholesale volumes sold increased 6%. It is estimated that weather contributed $7
million to the increase in electric utility margin, and the increased industrial
and other wholesale volumes and the NOx recovery rider contributed $8 million.

Margin from Asset Optimization Activities
Periodically, generation capacity is in excess of that needed to serve native
load and firm wholesale customers. The Company markets this unutilized capacity
to optimize the return on its owned generation assets. Substantially all of
these contracts are integrated with portfolio requirements around power supply
and delivery and are short-term purchase and sale transactions that expose the
Company to limited market risk.

Following is a reconciliation of asset optimization activity:

Accrued liabilities (2,797) (4,224) (2,807)


For the years ended December 31, 2003, 2002, and 2001, volumes sold into the
wholesale market were 4.3 GWh, 10.7 GWh, and 3.4 GWh, respectively, while
volumes purchased were 4.1 GWh in 2003, 10.3 GWh in 2002, and 2.9 GWh in 2001. A
portion of volumes purchased in the wholesale market is used to serve native
load and firm wholesale customers, and in 2003, greater amounts of purchased
power have been required for native load due to scheduled outages, which has
reduced capacity available for optimization. Additionally, volumes sold and
purchased were lower in 2003 compared to 2002 due to a shorter term focus in
hedging and optimization strategies. While volumes both sold and purchased in
the wholesale market have decreased during 2003, margin from optimization
activities has increased compared to 2002 due primarily to price volatility.
Despite the increased volumes in 2002, margins were lower in 2002 compared to
2001 due to reduced price volatility.

In July 2003, the EITF released EITF 03-11, "Reporting Realized Gains and Losses
on Derivative Instruments That Are Subject to FASB Statement No. 133 and Not
"Held for Trading Purposes" as Defined in Issue No. 02-3" (EITF 03-11). EITF
03-11 states that determining whether realized gains and losses on physically
settled derivative contracts should be reported in the Statement of Income on a
gross or net basis is a matter of judgment that depends on the relevant facts
and circumstances. The EITF contains a presumption that net settled derivative
contracts should be reported net in the Statement of Income. The Company adopted
EITF 03-11 as required on October 1, 2003.

After considering the facts and circumstances relevant to the asset optimization
portfolio, the Company believes presentation of these optimization activities on
a net basis is appropriate and has reclassified purchase contracts and
mark-to-market activity related to optimization activities from Purchased
electric energy to Electric utility revenues. Prior year financial information
has also been reclassified to conform to this net presentation.

Following is information regarding asset optimization activities included in
Electric utility revenues and Fuel for electric generation in the Statements of
Income.

- --------------------------------------------------------------------------------
Total throughput 31,547 31,988 31,923
================================================================================

Gas Utility margin for the year ended December 31, 2003, of $29.3 million
decreased $3.1 million, or 9%, compared to 2002. The decrease is primarily due
to estimates for unbilled revenue, the pricing of unaccounted for gas, and
reduced consumption per degree day per customer, all of which decreased margin
by approximately $2.8 million. Utility receipts taxes collected from customers
also decreased margin $0.5 million. Furthermore, the negative effect of high gas
prices on customer usage contributed to the decrease. Weather near normal and 2%
cooler than the prior year increased margin an estimated $0.2 million.

Gas Utility margin for the year ended December 31, 2002, of $32.4 million
increased $6.5 million compared to 2001. The increase is primarily due to
weather 4% cooler for the year and 26% colder in the fourth quarter and customer
growth of almost 1%.

Gas cost fluctuations have impacted customer usage during the years ended
December 31, 2003, 2002, and 2001. The average cost per dekatherm of gas
purchased in those years was $5.78 in 2003, $4.20 in 2002, and $5.20 in 2001.

Operating Expenses

Other Operating

For the year ended December 31, 2003, other operating expenses increased $5.6
million compared to 2002. The increase is principally caused by increased
distribution, plant, and transmission operating expenses; power plant and other
maintenance; customer service initiative costs; higher insurance premiums; and
prior year insurance recoveries.

Other operating expenses decreased $7.2 million for the year ended December 31,
2002, when compared to 2001. The decrease results primarily from insurance
recovery in 2002 of $2.8 million of maintenance costs incurred in 2001, and a
return to lower gas prices in 2002 compared to 2001.

Depreciation & Amortization

For the year ended December 31, 2003, depreciation and amortization increased
$2.6 million in 2003 compared to 2002, and $1.8 million in 2002 compared to
2001. The increased depreciation expense reflects depreciation of utility plant
placed into service including a full year for a gas-fired peaker unit placed
into service in June 2002, customer system upgrades, and other upgrades to
existing transmission and distribution facilities.

Income Taxes

For the year ended December 31, 2003, federal and state income taxes were
comparable to 2002. The increase in the effective rate from 33.3% for 2002, to
38.6% for 2003, reflects an increase in the Indiana state income tax rate from
4.5 % to 8.5% and other changes in the effective tax rate recognized in 2002.
The $9.0 million increase in 2002 compared to 2001 is principally due to higher
pre-tax earnings.

Taxes Other Than Income Taxes

Taxes other than income taxes increased $0.7 million in 2003 compared to 2002.
Utility plant additions have increased property values and as a result have
increased property taxes in 2003. The increase was partially offset by lower
utility receipts taxes. Taxes other than income taxes decreased $1.3 million in
2002 compared to 2001 as a result of lower revenues subject to gross receipts
tax.

Interest Expense

Interest expense increased $1.6 million in 2003 compared to 2002 and increased
$2.2 million in 2002 compared to 2001. The 2003 increase results from increased
debt outstanding which is due primarily to increased working capital
requirements resulting from the higher gas prices and NOx expenditures. The 2003
increase also reflects the impact of permanent financing completed in the third
quarter of 2003 whereby short term borrowings from VUHI and $65 million of
higher coupon third party debt were replaced with $25 million in equity and
$61.9 in long-term debt payable to VUHI. The 2002 increase is attributable to
higher outstanding borrowings during 2002 due to the funding of NOx expenditures
with short-term borrowing.

Rate Case Proceedings

On March 12, 2004, SIGECO (d/b/a Vectren Energy Delivery of Indiana, Inc.) filed
a petition with the IURC to adjust its base rates and charges for its gas
distribution business in southwestern Indiana. If the filing is approved, SIGECO
expects to increase its base (non-gas cost) rates by approximately $5.7 million
to cover the ongoing cost of operating and maintaining the approximately
3,000-mile distribution and storage system used to serve more than 110,000
customers. If finalized by the OUCC and ultimately approved by the IURC, the
agreement in principle would result in about a 5 percent increase for the
typical SIGECO residential customer who uses natural gas to heat his/her home.
The proposal will not affect the electric portion of the Company's customer
bills.

The petition only addresses "non-gas" costs, which are incurred to build,
operate and maintain the pipes, other equipment and systems that are used to
deliver gas. The petition indicates that SIGECO has reached an agreement in
principle with the OUCC regarding the proposed changes to the rates and charges.
The agreement in principle further provides for SIGECO's recovery through a
tracking mechanism of costs required to comply with a new federal law dealing
with pipeline safety.

As required by the regulatory process, SIGECO will be required to submit
information substantiating the proposed adjustment to its base rates. During the
processing of the case by the IURC, there will also be one or more public
hearings conducted regarding the proposal. The timing and ultimate outcome of
this regulatory initiative is uncertain.

Critical Accounting Policies

Management is required to make judgments, assumptions, and estimates that affect
the amounts reported in the financial statements and the related disclosures
that conform to accounting principles generally accepted in the United States.
Note 2 to the financial statements describes the significant accounting policies
and methods used in the preparation of the financial statements. Certain
estimates used in the financial statements are subjective and use variables that
require judgment. These include the estimates to perform goodwill and other
asset impairment tests. The Company makes other estimates in the course of
accounting for unbilled revenue, the effects of regulation, and intercompany
allocations that are critical to the Company's financial results but that are
less likely to be impacted by near term changes. Other estimates that
significantly affect the Company's results, but are not necessarily critical to
operations, include depreciation of utility plant, the valuation of derivative
contracts, and the allowance for doubtful accounts, among others. Actual results
could differ from these estimates.

Goodwill

Pursuant to SFAS No. 142, the Company performed an initial impairment analysis
of its goodwill, all of which resides in the Gas Utility Services operating
segment. Also consistent with SFAS 142, goodwill is tested for impairment
annually at the beginning of the year and more frequently if events or
circumstances indicate that an impairment loss has been incurred. Impairment
tests are performed at the reporting unit level which the Company has determined
to be consistent with its Gas Utility Services operating segment as identified
in Note 11 to the financial statements. An impairment test performed in
accordance with SFAS 142 requires that a reporting unit's fair value be
estimated. The Company used a discounted cash flow model to estimate the fair
value of its Gas Utility Services operating segment, and that estimated fair
value was compared to its carrying amount, including goodwill. The estimated
fair value was in excess of the carrying amount in both 2003 and 2002 and
therefore resulted in no impairment.

Estimating fair value using a discounted cash flow model is subjective and
requires significant judgment in applying a discount rate, growth assumptions,
company expense allocations, and longevity of cash flows. A 100 basis point
increase in the discount rate utilized to calculate the Gas Utility Services
segment's fair value also would have resulted in no impairment charge in 2003 or
2002.

Unbilled Revenues

To more closely match revenues and expenses, the Company records revenues for
all gas and electricity delivered to customers but not billed at the end of the
accounting period. The Company uses actual units billed during the month to
allocate unbilled units. Those allocated units are multiplied by rates in effect
during the month to calculate unbilled revenue at balance sheet dates. While
certain estimates are used in the calculation of unbilled revenue, the method
these estimates are derived from is not subject to near-term changes.

Regulation

At each reporting date, the Company reviews current regulatory trends in the
markets in which it operates. This review involves judgment and is critical in
assessing the recoverability of regulatory assets as well as the ability to
continue to account for its activities based on the criteria set forth in SFAS
No. 71 "Accounting for the Effects of Certain Types of Regulation" (SFAS 71).
Based on the Company's current review, it believes its regulatory assets are
probable of recovery. If all or part of the Company's operations cease to meet
the criteria of SFAS 71, a write-off of related regulatory assets and
liabilities could be required. In addition, the Company would be required to
determine any impairment to the carrying value of its utility plant and other
regulated assets. In the unlikely event of a change in the current regulatory
environment, such write-offs and impairment charges could be significant.

Intercompany Allocations

Support Services

Vectren and certain subsidiaries of Vectren provide corporate, general and
administrative services to the Company including legal, finance, tax, risk
management, and human resources, which includes charges for restricted stock
compensation and for pension and other postretirement benefits not directly
charged to subsidiaries. These costs have been allocated using various
allocators, primarily number of employees, number of customers and/or revenues.
Allocations are based on cost. Management believes that the allocation
methodology is reasonable and approximates the costs that would have been
incurred had the Company secured those services on a stand-alone basis. The
allocation methodology is not subject to near term changes.

Pension and Other Postretirement Obligations

Vectren satisfies the future funding requirements of its pension and other
postretirement plans and the payment of benefits from general corporate assets.
An allocation of expense is determined by Vectren's actuaries, comprised of only
service cost and interest on that service cost, by subsidiary based on headcount
at each measurement date, which occurs on September 30. These costs are directly
charged to individual subsidiaries. Other components of costs (such as interest
cost and asset returns) are charged to individual subsidiaries through the
corporate allocation process discussed above. Neither plan assets nor the FAS
87/106 liability is allocated to individual subsidiaries since these assets and
obligations are derived from corporate level decisions. Further, Vectren
satisfies the future funding requirements of plans and the payment of benefits
from general corporate assets. Management believes these direct charges when
combined with benefit-related corporate charges discussed in "support services"
above approximate costs that would have been incurred if the Company accounted
for benefit plans on a stand-alone basis.

Vectren estimates the expected return on plan assets, discount rate, rate of
compensation increase, and future health care costs, among other things, and
relies on actuarial estimates to assess the future potential liability and
funding requirements of pension and postretirement plans. Vectren used the
following weighted average assumptions to develop 2003 periodic benefit cost: a
discount rate of 6.75%, an expected return on plan assets before expenses of
9.0%, a rate of compensation increase of 4.25%, and a health care cost trend
rate of 10% in 2003 declining to 5% in 2006. During 2003, Vectren reduced the
discount rate and rate of compensation increase by 75 basis points to value 2003
ending pension and postretirement obligations due to a decline in benchmark
interest rates. The Company also lengthened to 2009 the time in which the health
care trend rate declines to 5% primarily due to increases in healthcare costs.
In addition, the Company reduced its 2004 expected return on plan assets 50
basis points from that used to estimate 2003 expense due to recent lower
investment returns and lower interest rates. Future changes in health care
costs, work force demographics, interest rates, or plan changes could
significantly affect the estimated cost of these future benefits that are
allocated to VUHI and its subsidiaries.






Impact of Recently Issued Accounting Guidance

SFAS 143

In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations" (SFAS 143). SFAS 143 requires entities to record the fair value of
a liability for an asset retirement obligation in the period in which it is
incurred. When the liability is initially recorded, the entity capitalizes a
cost by increasing the carrying amount of the related long-lived asset. Over
time, the liability is accreted to its present value, and the capitalized cost
is depreciated over the useful life of the related asset. Upon settlement of the
liability, an entity either settles the obligation for its recorded amount or
incurs a gain or loss upon settlement. The Company adopted this statement on
January 1, 2003. The adoption was not material to the Company's results of
operations or financial condition.

The Company collects an estimated cost of removal of its utility plant through
depreciation rates established by regulatory proceedings. As of December 31,
2003, and 2002, such removal costs approximated $48 million and $44 million,
respectively. In 2002, the cost of removal has been included in Other removal
costs, which is in noncurrent liabilities. In 2003, the Company re-characterized
other removal costs to Regulatory liabilities upon adoption of SFAS 143.

SFAS 149

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities" (SFAS 149). SFAS 149 amends and
clarifies the accounting guidance on (1) derivative instruments (including
certain derivative instruments embedded in other contracts) and (2) hedging
activities that fall within the scope of FASB Statement No. 133 (SFAS 133),
"Accounting for Derivative Instruments and Hedging Activities." SFAS 149 amends
SFAS 133 to reflect decisions that were made (1) as part of the process
undertaken by the Derivatives Implementation Group (DIG), which necessitated
amending SFAS 133, (2) in connection with other projects dealing with financial
instruments, and (3) regarding implementation issues related to the application
of the definition of a derivative. SFAS 149 also amends certain other existing
pronouncements which will result in more consistent reporting of contracts that
are derivatives in their entirety or that contain embedded derivatives that
warrant separate accounting. SFAS 149 is effective (1) for contracts entered
into or modified after June 30, 2003, with certain exceptions and (2) for
hedging relationships designated after June 30. The guidance is to be applied
prospectively. The adoption did not have a material effect on the Company's
results of operations or financial condition.

SFAS 150

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity" (SFAS 150).
SFAS 150 requires issuers to classify as liabilities the following three types
of freestanding financial instruments: mandatorily redeemable financial
instruments, obligations to repurchase the issuer's equity shares by
transferring assets, and certain obligations to issue a variable number of
shares. SFAS 150 was effective immediately for financial instruments entered
into or modified after May 31, 2003; otherwise, the standard was effective for
all other financial instruments at the beginning of the Company's third quarter
of 2003. In October 2003, the FASB issued further guidance regarding mandatorily
redeemable stock which is effective January 1, 2004, for the Company. The
adoption of SFAS 150 on January 1, 2004, did not affect the Company's results of
operations or financial condition.

FASB Interpretation (FIN) 45

In November 2002, the FASB issued FIN 45. FIN 45 clarifies the requirements for
a guarantor's accounting for and disclosure of certain guarantees issued and
outstanding and that a guarantor is required to recognize, at the inception of a
guarantee, a liability for the fair value of the obligations it has undertaken.
The initial recognition and measurement provisions were applicable on a
prospective basis to guarantees issued or modified after December 31, 2002.
Since that date, the adoption has not had a material effect on the Company's
results of operations or financial condition.

FIN 46/46-R (Revised in December 2003)

In January 2003, the FASB issued Interpretation 46, "Consolidation of Variable
Interest Entities" (FIN 46). FIN 46 addresses consolidation by business
enterprises of variable interest entities (VIE) and significantly changes the
consolidation requirements for those entities. FIN 46 is intended to achieve
more consistent application of consolidation policies related to VIE's and thus
improves comparability between enterprises engaged in similar activities when
those activities are conducted through VIE's. In December 2003, the FASB
completed its deliberations of proposed modifications to FIN 46 and decided to
codify both the proposed modifications and other decisions previously issued
through certain FASB Staff Positions into one document that was issued as a
revision to the original Interpretation (FIN 46-R). FIN 46-R currently applies
to VIE's created after January 31, 2003, and to VIE's in which an enterprise
obtains an interest after that date. For entities created prior to January 31,
2003, FIN 46 is to be adopted no later than the end of the first interim or
annual reporting period ending after March 15, 2004. Although management is
still evaluating the impact of FIN 46 and related Staff Positions on its
financial position and results of operations, the adoption is not expected to
have a material effect.

Staff Accounting Bulletin No. 104

In December 2003, the SEC published Staff Accounting Bulletin (SAB) No. 104,
"Revenue Recognition". This SAB updates portions of the SEC staff's interpretive
guidance provided in SAB 101 and included in Topic 13 of the Codification of
Staff Accounting Bulletins. SAB 104 deletes interpretative material no longer
necessary and conforms the interpretive material retained because of
pronouncements issued by the FASB's EITF on various revenue recognition topics,
including EITF 00-21, "Revenue Arrangements with Multiple Deliverables." The
Company's adoption of the standard did not have an impact on its revenue
recognition policies.

United States Securities and Exchange Commission (SEC) Informal Inquiry

As more fully described in the 2002 financial statements, the Company restated
its annual financial statements for 2000 and 2001, and its 2002 quarterly
results. The Company received an informal inquiry from the SEC with respect to
this restatement. In response, the Company met with the SEC staff and provided
information in response to their requests, with the most recent response
provided on July 26, 2003.

changes in assumptions, or other factors affecting such statements.





ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to various business risks associated with commodity
prices, interest rates, and counter-party credit. These financial exposures are
monitored and managed by the Company as an integral part of its overall risk
management program. The Company's risk management program includes, among other
things, the use of derivatives.

The Company also executes derivative contracts in the normal course of
operations while buying and selling commodities to be used in operations and
optimizing its generation assets.

Commodity Price Risk

The Company's regulated operations have limited exposure to commodity price risk
for purchases and sales of natural gas and electricity for retail customers due
to current Indiana and Ohio regulations, which subject to compliance with those
regulations, allow for recovery of the cost of such purchases through natural
gas and fuel cost adjustment mechanisms.

Electric sales and purchases in the wholesale power market and electric sales to
certain municipalities and large industrial customers are exposed to commodity
price risk associated with fluctuating commodity prices.

The Company's wholesale power marketing activities include asset optimization
activities that manage the utilization of available electric generating capacity
by entering into energy contracts that commit the Company to purchase and sell
electricity in the future. Commodity price risk results from forward positions
that commit the Company to deliver electricity. The Company mitigates price risk
exposure with planned unutilized generation capability and offsetting forward
purchase contracts. The Company accounts for asset optimization contracts that
are derivatives at fair value with the offset marked to market through earnings.

Sales to certain municipalities and large industrial customers are executed to
meet customer demand. Price risk from forward positions obligating the Company
to deliver commodities is mitigated using generating capability, and offsetting
forward purchase contracts. These contracts are expected to be settled by
physical receipt or delivery of the commodity.

Market risk resulting from commodity contracts is measured by management using
the potential impact on pre-tax earnings caused by the effect a 10% adverse
change in forward commodity prices might have on market sensitive derivative
positions outstanding on specific dates. For the years ended December 31, 2003,
and 2002, a 10% adverse change in forward commodity prices would have decreased
earnings by $3.0 million and $1.7 million, respectively, based upon open
positions existing on the last day of those years.

Interest Rate Risk

The Company is exposed to interest rate risk associated with its borrowing
arrangements. Its risk management program seeks to reduce the potentially
adverse effects that market volatility may have on interest expense. The
Company's risk management objective is for between 20% and 30% of its total debt
to be exposed to short-term interest rate volatility. However, there are times
when this targeted range of interest rate exposure may not be attained. To
manage this exposure, the Company may use derivative financial instruments. At
December 31, 2003, such debt obligations represented 18% of the Company's total
debt portfolio.

Market risk is estimated as the potential impact resulting from fluctuations in
interest rates on adjustable rate borrowing arrangements exposed to short-term
interest rate volatility. During 2003 and 2002, the weighted average combined
borrowings under these arrangements were $49.8 million and $92.4 million,
respectively. At December 31, 2003, and 2002, combined borrowings under these
arrangements were $83.8 million and $61.9 million, respectively. Based upon
average borrowing rates under these facilities during the years ended December
31, 2003, and 2002, an increase of 100 basis points (one percentage point) in
the rates would have increased interest expense by $0.5 million and $0.9
million, respectively.

Other Risks

By using forward purchase contracts and derivative financial instruments to
manage risk, the Company exposes itself to counter-party credit risk and market
risk. The Company manages exposure to counter-party credit risk by entering into
contracts with companies that can be reasonably expected to fully perform under
the terms of the contract. Counter-party credit risk is monitored regularly and
positions are adjusted appropriately to manage risk. Further, tools such as
netting arrangements and requests for collateral are also used to manage credit
risk. Market risk is the adverse effect on the value of a financial instrument
that results from a change in commodity prices or interest rates. The Company
attempts to manage exposure to market risk associated with commodity contracts
and interest rates by establishing parameters and monitoring those parameters
that limit the types and degree of market risk that may be undertaken.

The Company's customer receivables from gas and electric sales and gas
transportation services are primarily derived from a diversified base of
residential, commercial, and industrial customers located in Indiana. The
Company manages credit risk associated with its receivables by continually
reviewing creditworthiness and requests cash deposits or refunds cash deposits
based on that review.

Although the Company's regulated operations are exposed to limited commodity
price risk, volatile natural gas prices can result in higher working capital
requirements; increased expenses including unrecoverable interest costs,
uncollectible accounts expense, and unaccounted for gas; and some level of price
sensitive reduction in volumes sold. The Company mitigates these risks by
executing derivative contracts that manage the price of forecasted natural gas
purchases. These contracts are subject to regulation, which allows for
reasonable and prudent hedging costs to be recovered through rates. When
regulation is involved, SFAS 71 controls when the offset to mark-to-market
accounting is recognized in earnings.






ITEM 8. Financial Statements and Supplementary Data

MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS

The management of Southern Indiana Gas and Electric Company (SIGECO) is
responsible for the preparation of the financial statements and the related
financial data contained in this report. The financial statements are prepared
in conformity with accounting principles generally accepted in the United States
and follow accounting policies and principles applicable to regulated public
utilities.

The integrity and objectivity of the data in this report, including required
estimates and judgments, is the responsibility of management. Management
maintains a system of internal control and utilizes an internal auditing program
to provide reasonable assurance of compliance with Company policies and
procedures and the safeguard of assets.

The board of directors of Vectren Corporation (Vectren), the ultimate parent
company of SIGECO, pursues its responsibility for these financial statements
through its audit committee, which meets periodically with management, the
internal auditors, and the independent auditors, to assure that each is carrying
out its responsibilities. Both the internal auditors and the independent
auditors meet with the audit committee of Vectren's board of directors, with and
without management representatives present, to discuss the scope and results of
their audits, their comments on the adequacy of internal accounting control, and
the quality of financial reporting.

SOUTHERN INDIANA GAS AND ELECTRIC COMPANY
NOTES TO THE FINANCIAL STATEMENTS

1. Organization and Nature of Operations

Southern Indiana Gas and Electric Company (the Company or SIGECO), an Indiana
corporation, provides electric generation, transmission, and distribution
services to 8 counties in southwestern Indiana, including counties surrounding
Evansville, and participates in the wholesale power market. SIGECO also provides
natural gas distribution and transportation services to 10 counties in
southwestern Indiana, including counties surrounding Evansville. SIGECO is a
direct subsidiary of Vectren Utility Holdings, Inc. (VUHI). VUHI is a direct,
wholly owned subsidiary of Vectren Corporation (Vectren). SIGECO generally does
business as Vectren Energy Delivery of Indiana, Inc.

Vectren, an Indiana corporation, is an energy and applied technology holding
company headquartered in Evansville, Indiana. Vectren was organized on June 10,
1999, solely for the purpose of effecting the merger of Indiana Energy, Inc.
(Indiana Energy) and SIGCORP, Inc. (SIGCORP). On March 31, 2000, the merger of
Indiana Energy with SIGCORP and into Vectren was consummated with a tax-free
exchange of shares and has been accounted for as a pooling-of-interests in
accordance with Accounting Principles Board (APB) Opinion No. 16 "Business
Combinations."

Vectren's wholly owned subsidiary, VUHI, serves as the intermediate holding
company for its three operating public utilities: Indiana Gas, formerly a wholly
owned subsidiary of Indiana Energy, Southern Indiana Gas and Electric Company
(SIGECO), formerly a wholly owned subsidiary of SIGCORP, and the Ohio
operations. Both Vectren and VUHI are exempt from registration pursuant to
Section 3(a)(1) and 3(c) of the Public Utility Holding Company Act of 1935.

2. Summary of Significant Accounting Policies

A. Cash & Cash Equivalents
All highly liquid investments with an original maturity of three months or less
at the date of purchase are considered cash equivalents.

B. Inventories
Inventories consist of the following:

At December 31,
- --------------------------------------------------------------------------------
(In thousands) 2003 2002
- --------------------------------------------------------------------------------
Materials & supplies $ 17,304 $ 15,836
Gas in storage - at LIFO cost 8,599 12,880
Fuel (coal and oil) for electric generation 10,680 10,030
Emission allowances 631 907
- --------------------------------------------------------------------------------
Total inventories $ 37,214 $ 39,653
================================================================================

Based on the average cost of gas purchased during December, the cost of
replacing gas in storage carried at LIFO cost exceeded LIFO cost at December 31,
2003, and 2002, by approximately $30.1 million and $19.0 million, respectively.
Gas in storage of the Indiana regulated operations is stated at LIFO. All other
inventories are carried at average cost.

C. Utility Plant & Depreciation
Utility plant is stated at historical cost, including AFUDC. Depreciation of
utility property is provided using the straight-line method over the estimated
service lives of the depreciable assets.

The original cost of utility plant, together with depreciation rates expressed
as a percentage of original cost, follows:

(In thousands) 2003 2002
- -------------------------------------------------------------------------------------------------
Depreciation Depreciation
Rates as a Rates as a
Percent of Percent of
Original Cost Original Cost Original Cost Original Cost

Electric utility plant $ 1,322,365 3.4% $ 1,216,083 3.3%
Gas utility plant 170,865 3.0% 164,510 2.9%
Common utility plant 44,295 2.7% 41,621 2.6%
Construction work in progress 122,002 - 108,927 -
- -------------------------------------------------------------------------------------------------
Total original cost $ 1,659,527 $ 1,531,141
=================================================================================================


AFUDC represents the cost of borrowed and equity funds used for construction
purposes and is charged to construction work in progress during the construction
period and is included in Other - net in the Statements of Income. The total
AFUDC capitalized into utility plant and the portion of which was computed on
borrowed and equity funds for all periods reported follows:

Year Ended December 31,
- -------------------------------------------------------------------------------
(In thousands) 2003 2002 2001
- -------------------------------------------------------------------------------
AFUDC - equity funds $ 2,863 $ 1,746 $ 1,653
AFUDC - borrowed funds 1,904 1,933 1,371
- -------------------------------------------------------------------------------
Total AFUDC capitalized $ 4,767 $ 3,679 $ 3,024
===============================================================================

Maintenance and repairs, including the cost of removal of minor items of
property and planned major maintenance projects, are charged to expense as
incurred unless deferral is authorized by a rate order. When property that
represents a retirement unit is replaced or removed, the cost of such property
is charged to Utility plant, with an offsetting charge to Accumulated
depreciation and Regulatory liabilities for the cost of removal.

D. Impairment Review of Long-Lived Assets
Long-lived assets are reviewed as facts and circumstances indicate that the
carrying amount may be impaired. This review is performed in accordance with
SFAS No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets"
(SFAS 144), which the Company adopted on January 1, 2002. SFAS 144 establishes
one accounting model for all impaired long-lived assets and long-lived assets to
be disposed of by sale or otherwise. SFAS 144 requires the evaluation for
impairment involve the comparison of an asset's carrying value to the estimated
future cash flows the asset is expected to generate over its remaining life. If
this evaluation were to conclude that the carrying value of the asset is
impaired, an impairment charge would be recorded based on the difference between
the asset's carrying amount and its fair value (less costs to sell for assets to
be disposed of by sale) as a charge to operations or discontinued operations.

E. Goodwill
Goodwill arising from business combinations is accounted for in accordance with
SFAS No. 142, "Goodwill and Other Intangible Assets" (SFAS 142). The Company
adopted SFAS 142 on January 1, 2002. SFAS 142 changed the accounting for
goodwill from an amortization approach to an impairment-only approach. Thus,
amortization of goodwill that was not included as an allowable cost for
rate-making purposes ceased upon SFAS 142's adoption.

Goodwill is to be tested for impairment at a reporting unit level at least
annually. The impairment review consists of a comparison of the fair value of a
reporting unit to its carrying amount. If the fair value of a reporting unit is
less than its carrying amount, an impairment loss is recognized in operations.
Prior to the adoption of SFAS 142, the Company amortized goodwill on a
straight-line basis over 40 years. SFAS 142 required an initial impairment
review of all goodwill within six months of the adoption date.

As required by SFAS 142, amortization of goodwill ceased on January 1, 2002.
Amortization approximated $0.2 million ($0.1 million after tax) in 2001. The
Company's goodwill is included in the Gas Utility Services operating segment.
Initial impairment reviews to be performed within six months of adoption of SFAS
142 were completed and resulted in no impairment. The impairment test is
performed at the beginning of each year.

F. Regulation

SFAS 71
Retail public utility operations affecting Indiana customers are subject to
regulation by the IURC. The Company's accounting policies give recognition to
the rate-making and accounting practices of these agencies and to accounting
principles generally accepted in the United States, including the provisions of
SFAS No. 71 "Accounting for the Effects of Certain Types of Regulation" (SFAS
71). Regulatory assets represent probable future revenues associated with
certain incurred costs, which will be recovered from customers through the
rate-making process. Regulatory liabilities represent probable expenditures by
the Company for removal costs or future reductions in revenues associated with
amounts that are to be credited to customers through the rate-making process.

The Company assesses the recoverability of costs recognized as regulatory assets
and the ability to continue to account for its activities based on the criteria
set forth in SFAS 71. Based on current regulation, the Company believes such
accounting is appropriate. If all or part of the Company's operations cease to
meet the criteria of SFAS 71, a write-off of related regulatory assets and
liabilities could be required. In addition, the Company would be required to
determine any impairment to the carrying value of its utility plant and other
regulated assets.

Regulatory assets consist of the following:

At December 31,
- -------------------------------------------------------------------------------
(In thousands) 2003 2002
- -------------------------------------------------------------------------------
Future amounts recoverable from ratepayers:
Income taxes $ 9,184 $ 7,334
Other 858 -
- -------------------------------------------------------------------------------
10,042 7,334
Amounts deferred for future recovery:
Demand side management programs 24,888 23,844
Other 5,347 3,713
- -------------------------------------------------------------------------------
30,235 27,557
Amounts currently recovered through base rates:
Unamortized debt issue costs 4,515 3,011
Premiums paid to reacquire debt 5,915 3,739
Demand side management programs 2,746 3,170
- -------------------------------------------------------------------------------
13,176 9,920
Amounts currently recovered through authorized
Indiana tracking mechanisms 1,172 -
- -------------------------------------------------------------------------------
Total regulatory assets $ 54,625 $ 44,811
===============================================================================

The $13.2 million currently being recovered through base rates is earning a
return with a weighted average recovery period of 15.4 years. The Company has
rate orders for all deferred costs not yet in rates and therefore believes that
future recovery is probable.





Regulatory liabilities & other removal costs consist of the following:

At December 31,
- -------------------------------------------------------------------------------
(In thousands) 2003 2002
- -------------------------------------------------------------------------------
Cost of removal $ 48,153 $ -
Other removal costs - 43,936
- -------------------------------------------------------------------------------
Total regulatory liabilities &
other removal costs $ 48,153 $ 43,936
===============================================================================

SFAS 143 & Other Removal Costs
In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations" (SFAS 143). SFAS 143 requires entities to record the fair value of
a liability for an asset retirement obligation in the period in which it is
incurred. When the liability is initially recorded, the entity capitalizes a
cost by increasing the carrying amount of the related long-lived asset. Over
time, the liability is accreted to its present value, and the capitalized cost
is depreciated over the useful life of the related asset. Upon settlement of the
liability, an entity either settles the obligation for its recorded amount or
incurs a gain or loss upon settlement. The Company adopted this statement on
January 1, 2003. The adoption was not material to the Company's results of
operations.

The Company collects an estimated cost of removal of its utility plant through
depreciation rates established by regulatory proceedings. As of December 31,
2003, and 2002, such removal costs approximated $48 million and $44 million,
respectively. In 2002, the cost of removal has been included in Other removal
costs, which is in noncurrent liabilities. In 2003, the Company re-characterized
other removal costs to Regulatory liabilities upon adoption of SFAS 143.

Refundable or Recoverable Gas Costs, Fuel for Electric Production & Purchased
Power
All metered gas rates contain a gas cost adjustment clause that allows the
Company to charge for changes in the cost of purchased gas. Metered electric
rates contain a fuel adjustment clause that allows for adjustment in charges for
electric energy to reflect changes in the cost of fuel and the net energy cost
of purchased power. Metered electric rates also allow recovery, through a
quarterly rate adjustment mechanism, for the margin on electric sales lost due
to the implementation of demand side management programs.

The Company records any under-or-over-recovery resulting from gas and fuel
adjustment clauses each month in revenues. A corresponding asset or liability is
recorded until the under-or-over-recovery is billed or refunded to utility
customers. The cost of gas sold is charged to operating expense as delivered to
customers, and the cost of fuel for electric generation is charged to operating
expense when consumed.

G. Revenues
Revenues are recorded as products and services are delivered to customers. To
more closely match revenues and expenses, the Company records revenues for all
gas and electricity delivered to customers but not billed at the end of the
accounting period.

H. Excise and Utility Receipts Taxes
Excise taxes and a portion of utility receipts taxes are included in rates
charged to customers. Accordingly, the Company records these taxes received as a
component of Operating revenues. Excise and utility receipts taxes paid are
recorded as a component of Taxes other than income taxes.

I. Earnings Per Share
Earnings per share are not presented as SIGECO's common stock is wholly owned by
Vectren Utility Holdings, Inc.

J. Other Significant Policies
Included elsewhere in these notes are significant accounting policies related to
intercompany allocations and income taxes (Note 3) and derivatives (Note 10).

K. Use of Estimates
The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

L. Reclassification
Certain prior year amounts have been reclassified in the financial statements
and accompanying notes to conform to 2003 classifications.

3. Transactions with Other Vectren Companies

Support Services and Purchases
Vectren and certain subsidiaries of Vectren provided corporate and general and
administrative services to the Company including legal, finance, tax, risk
management, human resources, which includes charges for restricted stock
compensation and for pension and other postretirement benefits not directly
charged to subsidiaries. These costs have been allocated using various
allocators, primarily number of employees, number of customers and/or revenues.
Allocations are based on cost. SIGECO received corporate allocations totaling
$42.3 million, $45.2 million, and $43.5 million for the years ended December 31,
2003, 2002, and 2001, respectively.

Vectren Fuels, Inc., a wholly owned subsidiary of Vectren, owns and operates
coal mines from which SIGECO purchases fuel used for electric generation.
Amounts paid for such purchases for the years ended December 31, 2003, 2002, and
2001, totaled $77.0 million, $62.1 million, and $58.4 million, respectively.

Retirement Plans and Other Postretirement Benefits
Vectren has multiple defined benefit pension plans and postretirement plans that
require accounting as described in SFAS No. 87 "Employers' Accounting for
Pensions" and SFAS No. 106 "Employers' Accounting for Postretirement Benefits
Other Than Pensions," respectively. An allocation of expense is determined by
Vectren's actuaries, comprised of only service cost and interest on that service
cost, by subsidiary based on headcount at each measurement date. These costs are
directly charged to individual subsidiaries. Other components of costs (such as
interest cost and asset returns) are charged to individual subsidiaries through
the corporate allocation process discussed above. Neither plan assets nor the
FAS 87/106 liability is allocated to individual subsidiaries since these assets
and obligations are derived from corporate level decisions. Further, Vectren
satisfies the future funding requirements of plans and the payment of benefits
from general corporate assets. This allocation methodology is consistent with
"multiemployer" benefit accounting as described in SFAS 87 and 106.

For the years ended December 31, 2003, 2002, and 2001, periodic pension costs
totaling $2.4 million, $2.6 million and $2.3 million, respectively, was directly
charged by Vectren to the Company. For the years ended December 31, 2003, 2002,
and 2001, other periodic postretirement benefit costs totaling $0.5 million,
$0.6 million, and $0.5 million, respectively, was directly charged by Vectren to
the Company. As of December 31, 2003, and 2002, $26.4 million and $24.1 million,
respectively, is included in Deferred credits & other liabilities and represents
expense directly charged to the Company that is yet to be funded to Vectren.

The recently enacted Medicare Prescription Drug, Improvement and Modernization
Act of 2003 (the Medicare Act) provides a prescription drug benefit as well as a
federal subsidy to sponsors of certain retiree health care benefit plans. As
allowed by FASB Staff Position No. 106-1 (FSP 106-1), Vectren has elected to
defer reflecting the effects of the Medicare Act on the accumulated benefit
obligation and net periodic postretirement benefit cost in its 2003 financial
statements. Vectren's deferral election expires upon the occurrence of any event
that triggers a required remeasurement of plan assets or obligations, or upon
the issuance of specific authoritative guidance on the accounting for the
federal subsidy. Such guidance is pending and when issued could require the
Company to adjust previously reported information. Upon expiration of Vectren's
deferral or the issuance of guidance, Vectren's implementation of the Medicare
Act may impact SIGECO's financial statements.



Cash Management Arrangements
The Company participates in a centralized cash management program with Vectren,
other wholly owned subsidiaries, and banks which permits funding of checks as
they are presented. See Note 5 regarding long-term and short-term intercompany
borrowing arrangements.

Guarantees of Parent Company Debt
Vectren's three operating utility companies, SIGECO, Indiana Gas, and VEDO are
guarantors of VUHI's $346 million commercial paper program, of which
approximately $184.4 million is outstanding at December 31, 2003, and VUHI's
$550 million unsecured senior notes outstanding at December 31, 2003. The
guarantees are full and unconditional and joint and several, and VUHI has no
subsidiaries other than the subsidiary guarantors.

Equity-Based Incentive Plans
The Company does not have equity-based compensation plans separate from Vectren.
An insignificant number of the Company's employees participate in Vectren's
equity-based compensation plans.

Income Taxes
Vectren and subsidiary companies file a consolidated federal income tax return.
For financial reporting purposes, SIGECO's current and deferred tax expense is
computed on a separate company basis. The components of income tax expense and
utilization of investment tax credits follow:

Year Ended December 31,

A reconciliation of the federal statutory rate to the effective income tax rate
follows:

Year Ended December 31,
- --------------------------------------------------------------------------------
2003 2002 2001
- --------------------------------------------------------------------------------
Statutory rate 35.0 % 35.0 % 35.0 %
State & local taxes, net of federal benefit 5.6 2.2 2.9
Amortization of investment tax credit (1.6) (1.5) (2.2)
All other - net (0.4) (2.4) (0.8)
- --------------------------------------------------------------------------------
Effective tax rate 38.6 % 33.3 % 34.9 %
================================================================================

The liability method of accounting is used for income taxes under which deferred
income taxes are recognized to reflect the tax effect of temporary differences

4. Transactions with Vectren Affiliates

ProLiance Energy, LLC
ProLiance Energy, LLC (ProLiance), a nonregulated energy marketing affiliate of
Vectren and Citizens Gas and Coke Utility (Citizens Gas), provides natural gas
and related services to Indiana Gas, the Ohio operations, Citizens Gas and
others. ProLiance also began providing service to SIGECO in 2002. ProLiance's
primary business is optimizing the gas portfolios of utilities and providing
services to large end use customers.

Purchases from ProLiance for resale and for injections into storage for the
years ended December 31, 2003 and 2002, totaled $72.8 million and $25.6 million,
respectively. Amounts owed to ProLiance at December 31, 2003, and 2002, for
those purchases were $8.3 million and $10.0 million, respectively, and are
included in Accounts payable to affiliated companies in the Balance Sheets.
Amounts charged by ProLiance for gas supply services are established by supply
agreements with each utility.

Other Affiliate Transactions Vectren has ownership interests in other affiliated
companies accounted for using the equity method of accounting that perform
underground construction and repair, facilities locating, and meter reading
services to the Company. For the years ended December 31, 2003, 2002, and 2001,
fees for these services and construction-related expenditures paid by the
Company to Vectren affiliates totaled $0.3 million, less than $0.1 million, and
zero in 2001, respectively. Amounts charged by these affiliates are market
based. Amounts owed to unconsolidated affiliates other than ProLiance totaled
less than $0.1 million and zero at December 31, 2003, and 2002, respectively.

5. Borrowing Arrangements & Other Financing Transactions

Short-Term Borrowings SIGECO mainly relies on the short-term borrowing
arrangements of VUHI for its short-term working capital needs. Borrowings,
including third party borrowings, outstanding at December 31, 2003, and 2002,
were $83.8 million and $39.4 million, respectively. The intercompany credit line
totals $150 million, but periodically may be limited by VUHI's available
capacity ($162 million of additional capacity at December 31, 2003) and is
subject to the same terms and conditions as VUHI's commercial paper program.
Short-term borrowings bear interest at VUHI's weighted average daily cost of
short-term funds. Additionally, at December 31, 2003, the Company has
approximately $5 million of short-term borrowing capacity with third parties to
supplement its intercompany borrowing arrangements, of which $4.2 million is
available. See the table below for interest rates and outstanding balances:

Issuance Payable to VUHI in 2003
In 2003, the Company issued $61.9 million of long-term debt payable to VUHI. The
note has terms identical to the terms of notes issued by VUHI in July 2003
through a public offering. Those notes have an interest rate of 5.75% priced at
99.177% to yield 5.80% to maturity and are due August 2018. They have no sinking
fund requirements, and interest payments are due semi-annually. The notes may be
called by VUHI, in whole or in part, at any time for an amount equal to accrued
and unpaid interest, plus the greater of 100% of the principal amount or the sum
of the present values of the remaining scheduled payments of principal and
interest, discounted to the redemption date on a semi-annual basis at the
Treasury Rate, as defined in VUHI's indenture, plus 25 basis points.

Issuances Payable to VUHI in 2001 and 2002
In 2001, the Company issued a note payable to VUHI for $49.5 million, and in
2002 issued a note payable to VUHI for $37.1 million. These two notes comprise
the $86.6 million of long-term debt due to VUHI at December 31, 2002.

The terms of these notes are identical to the terms of notes issued by VUHI in
December 2001 through a public offering (December Notes). The December Notes
have an aggregate principal amount of $250.0 million and an interest rate of
6.625%, priced at 99.302% to yield 6.69% to maturity. The December Notes have no
sinking fund requirements, and interest payments are due semi-annually. The
December Notes are due December 2011, but may be called by VUHI, in whole or in
part, at any time for an amount equal to accrued and unpaid interest, plus the
greater of 100% of the principal amount of the notes to be redeemed or the sum
of the present values of the remaining scheduled payments of principal and
interest, discounted to the redemption date on a semi-annual basis at the
Treasury Rate, as defined in VUHI's indenture, plus 25 basis points.

Debt Call
During 2003, the Company called two first mortgage bonds. The first bond had a
principal amount of $45.0 million, an interest rate of 7.60%, was originally due
in 2023, and was redeemed at 103.745% of its stated principal amount. The second
bond had a principal amount of $20.0 million, an interest rate of 7.625%, was
originally due in 2025, and was redeemed at 103.763% of the stated principal
amount. Pursuant to regulatory authority, the premiums paid to retire the net
carrying value of these notes totaling $2.4 million were deferred in Regulatory
assets. The proceeds to fund the early redemption were received from VUHI in the
form of new long-term debt discussed above and $25 million in additional equity.
To generate the initial proceeds to fund these transactions, in July 2003, VUHI
completed a public offering of long-term debt netting proceeds of approximately
$203 million, and, in August 2003, Vectren completed a public offering of common
stock netting proceeds of approximately $163 million.

Other Financing Transactions
At December 31, 2002, the Company had $26.6 million of adjustable rate senior
unsecured bonds which could, at the election of the bondholder, be tendered to
the Company when interest rates are reset. Such bonds were classified as
Long-term debt subject to tender. During 2003, the Company re-marketed $4.6
million of the bonds through 2020 at a 4.5% fixed interest rate and remarketed
$22.0 million of the bonds through 2030 at a 5.0% fixed interest rate. The bonds
are now classified in Long-term debt.

Additionally, during 2003, the Company re-marketed $22.5 million of first
mortgage bonds subject to interest rate exposure on a long term basis. The $22.5
million of mortgage bonds were remarketed through 2024 at a 4.65% fixed interest
rate.

Long-Term Debt Sinking Fund Requirements & Maturities
The annual sinking fund requirement of SIGECO's first mortgage bonds is one
percent of the greatest amount of bonds outstanding under the Mortgage
Indenture. This requirement may be satisfied by certification to the Trustee of
unfunded property additions in the prescribed amount as provided in the Mortgage
Indenture. SIGECO intends to meet the 2004 sinking fund requirement by this
means and, accordingly, the sinking fund requirement for 2004 is excluded from
Current liabilities in the Balance Sheets. At December 31, 2003, $502.0 million
of SIGECO's utility plant remained unfunded under SIGECO's Mortgage Indenture.

There are no maturities and/or sinking fund requirements on long-term debt
during the five years following 2003.

Long-Term Debt Put & Call Provisions
Certain long-term debt issues contain put and call provisions that can be
exercised on various dates before maturity. The put or call provisions are not
triggered by specific events, but are based upon dates stated in the note
agreements, such as when notes are re-marketed. Debt which may be put to the
Company during the years following 2003 (in millions) is $10.0 in 2004, zero in
2005, $53.7 in 2006, zero in 2007, zero in 2008, and $80.0 thereafter. Debt that
may be put to the Company within one year is classified as Long-term debt
subject to tender in current liabilities.

Covenants
Both long-term and short-term borrowing arrangements contain customary default
provisions; restrictions on liens, sale leaseback transactions, mergers or
consolidations, and sales of assets; and restrictions on leverage and interest
coverage, among other restrictions. As of December 31, 2003, the Company was in
compliance with all financial covenants.

6. Cumulative Preferred Stock

Redemption of Preferred Stock
Nonredeemable preferred stock containing call options was redeemed during
September 2001 for a total redemption price of $9.8 million. The 4.80%, $100 par
value preferred stock was redeemed at its stated call price of $110 per share,
plus accrued and unpaid dividends totaling $1.35 per share. The 4.75%, $100 par
value preferred stock was redeemed at its stated call price of $101 per share,
plus accrued and unpaid dividends totaling $0.97 per share. Prior to the
redemptions, there were 85,519 shares of the 4.80% Series outstanding and 3,000
shares of the 4.75% Series outstanding.

In September 2001, the 6.50%, $100 par value of redeemable preferred stock was
redeemed for a total redemption price of $7.9 million at $104.23 per share, plus
$0.73 per share in accrued and unpaid dividends. Prior to the redemption, there
were 75,000 shares outstanding.

The loss on redemption of $1.2 million in 2001 is reflected in Retained
earnings.

Redeemable, Special
This series of redeemable preferred stock has a dividend rate of 8.50% and in
the event of involuntary liquidation the amount payable is $100 per share, plus
accrued dividends. This series may be redeemed at $100 per share, plus accrued
dividends on any of its dividend payment dates, and is also callable at the
Company's option at a rate of 1,160 shares per year. As of December 31, 2003,
and 2002, there were 2,277 shares and 3,437 shares outstanding, respectively.

7. Commitments & Contingencies

Commitments
Firm purchase commitments for commodities total (in millions) $26.3 in 2004 and
$8.4 in 2005. Firm purchase commitment for utility and non-utility plant total
$98.4 million.

United States Securities and Exchange Commission (SEC) Informal Inquiry
As more fully described in the 2002 financial statements, the Company restated
its annual financial statements for 2000 and 2001, and its 2002 quarterly
results. The Company received an informal inquiry from the SEC with respect to
this restatement. In response, the Company met with the SEC staff and provided
information in response to their requests, with the most recent response
provided on July 26, 2003.

Legal Proceedings
The Company is party to various legal proceedings arising in the normal course
of business. In the opinion of management, there are no legal proceedings
pending against the Company that are likely to have a material adverse effect on
its financial position or results of operations. See Note 8 regarding
environmental matters.

8. Environmental Matters

Clean Air Act

NOx SIP Call Matter
The Clean Air Act (the Act) requires each state to adopt a State Implementation
Plan (SIP) to attain and maintain National Ambient Air Quality Standards (NAAQS)
for a number of pollutants, including ozone. If the USEPA finds a state's SIP
inadequate to achieve the NAAQS, the USEPA can call upon the state to revise its
SIP (a SIP Call).

In October 1998, the USEPA issued a final rule "Finding of Significant
Contribution and Rulemaking for Certain States in the Ozone Transport Assessment
Group Region for Purposes of Reducing Regional Transport of Ozone," (63 Fed.
Reg. 57355). This ruling found that the SIP's of certain states, including
Indiana, were substantially inadequate since they allowed for nitrogen oxide
(NOx) emissions in amounts that contributed to non-attainment with the ozone
NAAQS in downwind states. The USEPA required each state to revise its SIP to
provide for further NOx emission reductions. The NOx emissions budget, as
stipulated in the USEPA's final ruling, requires a 31% reduction in total NOx
emissions from Indiana.

In June 2001, the Indiana Air Pollution Control Board adopted final rules to
achieve the NOx emission reductions required by the NOx SIP Call. Indiana's SIP
requires the Company to lower its system-wide NOx emissions to .141 lbs./MMBTU
by May 31, 2004, (the compliance date). This is a 65% reduction in emission
levels.

The Company has initiated steps toward compliance with the revised regulations.
These steps include installing Selective Catalytic Reduction (SCR) systems at
Culley Generating Station Unit 3 (Culley), Warrick Generating Station Unit 4,
and A.B. Brown Generating Station Units 1 and 2. SCR systems reduce flue gas NOx
emissions to atmospheric nitrogen and water using ammonia in a chemical
reaction. This technology is known to currently be the most effective method of
reducing NOx emissions where high removal efficiencies are required.

The IURC has issued orders that approve:
o the Company's project to achieve environmental compliance by
investing in clean coal technology;
o a total capital cost investment for this project up to $244 million
(excluding AFUDC), subject to periodic review of the actual costs incurred;
o a mechanism whereby, prior to an electric base rate case, the Company may
recover through a rider that is updated every six months, an eight percent
return on its weighted capital costs for the project; and
o ongoing recovery of operating costs, including depreciation and purchased
emission allowances through a rider mechanism, related to the clean coal
technology once the facility is placed into service.

Based on the level of system-wide emissions reductions required and the control
technology utilized to achieve the reductions, the current estimated clean coal
technology construction cost is consistent with amounts approved in the IURC's
orders and is expected to be expended during the 2001-2006 period. Through
December 31, 2003, $145.2 million has been expended. After the equipment is
installed and operational, related annual operating expenses, including
depreciation expense, are estimated to be between $24 million and $27 million. A
portion of those expenses began in October 2003 when the Culley SCR became
operational. The 8 percent return on capital investment approximates the return
authorized in the Company's last electric rate case in 1995 and includes a
return on equity.

The Company expects to achieve timely compliance as a result of the project.
Construction of the first SCR at Culley was placed into service in October 2003,
and construction of the Warrick 4 and Brown SCR's is proceeding on schedule.
Installation of SCR technology as planned is expected to reduce the Company's
overall NOx emissions to levels compliant with Indiana's NOx emissions budget
allotted by the USEPA. Therefore, the Company has recorded no accrual for
potential penalties that may result from noncompliance.

Culley Generating Station Litigation
In the late 1990's, the USEPA initiated an investigation under Section 114 of
the Act of SIGECO's coal-fired electric generating units in commercial operation
by 1977 to determine compliance with environmental permitting requirements
related to repairs, maintenance, modifications, and operations changes. The
focus of the investigation was to determine whether new source review permitting
requirements were triggered by such plant modifications, and whether the best
available control technology was, or should have been used. Numerous electric
utilities were, and are currently, being investigated by the USEPA under an
industry-wide review for compliance. In July 1999, SIGECO received a letter from
the Office of Enforcement and Compliance Assurance of the USEPA discussing the
industry-wide investigation, vaguely referring to an investigation of SIGECO and
inviting SIGECO to participate in a discussion of the issues. No specifics were
noted; furthermore, the letter stated that the communication was not intended to
serve as a notice of violation. Subsequent meetings were conducted in September
and October 1999 with the USEPA and targeted utilities, including SIGECO,
regarding potential remedies to the USEPA's general allegations.

On November 3, 1999, the USEPA filed a lawsuit against seven utilities,
including SIGECO. SIGECO's suit was filed in the U.S. District Court for the
Southern District of Indiana. The USEPA alleged that, beginning in 1992, SIGECO
violated the Act by (1) making modifications to its Culley Generating Station in
Yankeetown, Indiana without obtaining required permits, (2) making major
modifications to the Culley Generating Station without installing the best
available emission control technology, and (3) failing to notify the USEPA of
the modifications. In addition, the lawsuit alleged that the modifications to
the Culley Generating Station required SIGECO to begin complying with federal
new source performance standards at its Culley Unit 3. The USEPA also issued an
administrative notice of violation to SIGECO making the same allegations, but
alleging that violations began in 1977.

On June 6, 2003, SIGECO, the Department of Justice (DOJ), and the USEPA
announced an agreement that would resolve the lawsuit. The agreement was
embodied in a consent decree filed in U.S. District Court for the Southern
District of Indiana. The mandatory public comment period has expired, and no
comments were received. The Court entered the consent decree on August 13, 2003.

Under the terms of the agreement, the DOJ and USEPA have agreed to drop all
challenges of past maintenance and repair activities at the Culley coal-fired
units. In reaching the agreement, SIGECO did not admit to any allegations in the
government's complaint, and SIGECO continues to believe that it acted in
accordance with applicable regulations and conducted only routine maintenance on
the units. SIGECO has entered into this agreement to further its continued
commitment to improve air quality and avoid the cost and uncertainties of
litigation.

Under the agreement, SIGECO has committed to:
o either repower Culley Unit 1 (50 MW) with natural gas, which would
significantly reduce air emissions from this unit, and equip it with SCR
control technology for further reduction of nitrogen oxide, or cease
operation of the unit by December 31, 2006;
o operate the existing SCR control technology recently installed on Culley
Unit 3 (287 MW) year round at a lower emission rate than that currently
required under the NOx SIP Call, resulting in further nitrogen oxide
reductions;
o enhance the efficiency of the existing scrubber at Culley Units 2
and 3 for additional removal of sulphur dioxide emissions;
o install a baghouse for further particulate matter reductions at
Culley Unit 3 by June 30, 2007;
o conduct a Sulphuric Acid Reduction Demonstration Project as an
environmental mitigation project designed to demonstrate an advance in
pollution control technology for the reduction of sulfate emissions; and
o pay a $600,000 civil penalty.

The Company anticipates that the settlement would result in total capital
expenditures through 2007 in a range between $16 million and $28 million. Other
than the $600,000 civil penalty, which was accrued in the second quarter of
2003, the implementation of the settlement, including these capital expenditures
and related operating expenses, are expected to be recovered through rates.



Information Request
On January 23, 2001, SIGECO received an information request from the USEPA under
Section 114 of the Act for historical operational information on the Warrick and
A.B. Brown generating stations. SIGECO has provided all information requested
with the most recent correspondence provided on March 26, 2001.

Manufactured Gas Plants
In October 2002, the Company received a formal information request letter from
the IDEM regarding five manufactured gas plants owned and/or operated by SIGECO
and not currently enrolled in the IDEM's VRP. In response, SIGECO submitted to
the IDEM the results of preliminary site investigations conducted in the
mid-1990's. These site investigations confirmed that based upon the conditions
known at the time, the sites posed no risk to human health or the environment.
Follow up reviews have been initiated by the Company to confirm that the sites
continue to pose no such risk.

On October 6, 2003, SIGECO filed applications to enter four of the manufactured
gas plant sites in IDEM's VRP. The remaining site is currently being addressed
in the VRP by another Indiana utility. SIGECO is adding its four sites into the
renewal of the global Voluntary Remediation Agreement that Indiana Gas has in
place with IDEM for its manufactured gas plant sites. The total costs, net of
other potentially responsible parties involvement and insurance recoveries, that
may be incurred in connection with further investigation, and if necessary,
remedial work at the four SIGECO sites cannot be determined at this time.

9. Rate & Regulatory Matters

As a result of an appeal of a generic order issued by the IURC in August 1999
regarding guidelines for the recovery of purchased power costs, SIGECO entered
into a settlement agreement with the OUCC that provides certain terms with
respect to the recoverability of such costs. The settlement, originally approved
by the IURC in August 2000, has been extended by agreement through March 2004,
and discussions regarding further extension of the settlement term are ongoing.
Under the settlement, SIGECO can recover the entire cost of purchased power up
to an established benchmark, and during forced outages, SIGECO will bear a
limited share of its purchased power costs regardless of the market costs at
that time. Based on this agreement, SIGECO believes it has limited its exposure
to unrecoverable purchased power costs.

10. Derivatives & Other Financial Instruments

Accounting Policy for Derivatives
The Company executes derivative contracts in the normal course of operations
while buying and selling commodities to be used in operations, optimizing its
generation assets, and managing risk.

When an energy contract that is a derivative is designated and documented as a
normal purchase or normal sale, it is exempted from mark-to-market accounting.
Otherwise, energy contracts and financial contracts that are derivatives are
recorded at market value as current or noncurrent assets or liabilities
depending on their value and on when the contracts are expected to be settled.
The offset resulting from carrying the derivative at fair value on the balance
sheet is charged to earnings unless it qualifies as a hedge or is subject to
SFAS 71. When hedge accounting is appropriate, the Company assesses and
documents hedging relationships between the derivative contract and underlying
risks as well as its risk management objectives and anticipated effectiveness.
When the hedging relationship is highly effective, derivatives are designated as
hedges. The market value of the effective portion of the hedge is marked to
market in accumulated other comprehensive income for cash flow hedges or as an
adjustment to the underlying's basis for fair value hedges. The ineffective
portion of hedging arrangements is marked-to-market through earnings. The offset
to contracts affected by SFAS 71 are marked-to-market as a regulatory asset or
liability. Market value for all derivative contracts is determined using quoted
market prices from independent sources. Following is a more detailed discussion
of the Company's use of mark-to-market accounting in three primary areas: asset
optimization, natural gas procurement, and interest rate management.

Asset Optimization
Periodically, generation capacity is in excess of that needed to serve retail
and firm wholesale customers. The Company markets this unutilized capacity to
optimize the return on its owned generation assets. Substantially all of these
contracts are integrated with portfolio requirements around power supply and
delivery and are primarily short-term purchase and sale contracts that expose
the Company to limited market risk. Contracts with counter-parties subject to
master netting arrangements are presented net in the Balance Sheets. Asset
optimization contracts are recorded at market value. Changes in market value,
which is a function of the normal decline in market value as earnings are
realized and the fluctuation in market value resulting from price volatility,
are recorded in Electric utility revenues.

Asset optimization contracts recorded at market value at December 31, 2003,
totaled $2.4 million of Prepayments & other current assets and $2.8 million of
Accrued liabilities, compared to $3.5 million of Prepayments & other current
assets and $4.2 million of Accrued liabilities at December 31, 2002.

In July 2003, the EITF released EITF 03-11, "Reporting Realized Gains and Losses
on Derivative Instruments That Are Subject to FASB Statement No. 133 and Not
"Held for Trading Purposes" as Defined in Issue No. 02-3" (EITF 03-11). EITF
03-11 states that determining whether realized gains and losses on physically
settled derivative contracts should be reported in the Statement of Income on a
gross or net basis is a matter of judgment that depends on the relevant facts
and circumstances. The EITF contains a presumption that net settled derivative
contracts should be reported net in the Statement of Income. The Company adopted
EITF 03-11 as required on October 1, 2003.

After considering the facts and circumstances relevant to the asset optimization
portfolio, the Company believes presentation of these optimization activities on
a net basis is appropriate and has reclassified purchase contracts and
mark-to-market activity related to optimization activities from Purchased
electric energy to Electric utility revenues. Prior year financial information
has also been reclassified to conform to this net presentation.

Following is information regarding asset optimization activities included in
Electric utility revenues and Fuel for electric generation in the Statements of
Income:

============================================================================

Natural Gas Procurement Activity
The Company's operations have limited exposure to commodity price risk for
purchases and sales of natural gas and electricity for retail customers due to
current Indiana regulations which, subject to compliance with those regulations,
allow for recovery of such purchases through natural gas and fuel cost
adjustment mechanisms. Although the Company's operations are exposed to limited
commodity price risk, volatile natural gas prices can result in higher working
capital requirements, increased expenses including unrecoverable interest costs,
uncollectible accounts expense, and unaccounted for gas, and some level of
price- sensitive reduction in volumes sold. The Company mitigates these risks by
executing derivative contracts that manage the price of forecasted natural gas
purchases. These contracts are subject to regulation which allows for reasonable
and prudent hedging costs to be recovered through rates. When regulation is
involved, SFAS 71 controls when the offset to mark-to-market accounting is
recognized in earnings. The market value of natural gas procurement derivative
contracts at December 31, 2003, was not significant.

Impact of Adoption of SFAS 133
In June 1998, the FASB issued SFAS 133 which required that every derivative
instrument be recorded on the balance sheet as an asset or liability measured at
its market value and that a change in the derivative's market value be
recognized currently in earnings unless specific hedge criteria are met.

SFAS 133, as amended, required that as of the date of initial adoption, the
difference between the market value of derivative instruments recorded on the
balance sheet and the previous carrying amount of those derivatives be reported
in net income or other comprehensive income, as appropriate.

Resulting from the adoption of SFAS 133, certain asset optimization contracts
that are periodically settled net were required to be recorded at market value.
Previously, the Company accounted for these contracts on settlement. The
cumulative impact of the adoption of SFAS 133 resulting from marking these
contracts to market on January 1, 2001, was an earnings gain of approximately
$1.8 million ($1.1 million net of tax) recorded as a cumulative effect of
accounting change. SFAS 133 did not impact other commodity contracts because
they were normal purchases and sales specifically excluded from the provisions
of SFAS 133 and did not impact the Company's cash flow hedges because they had
no value on the date of adoption.

Fair Value of Other Financial Instruments
The carrying values and estimated fair values of the Company's other financial
instruments follow:


At December 31,
- -------------------------------------------------------------------------------------
2003 2002
---------------------- ----------------------
Carrying Est. Fair Carrying Est. Fair
(In thousands) Amount Value Amount Value
- ----------------------------------- --------- --------- --------- ---------

Long term debt $ 228,615 $ 239,407 $ 294,615 $ 313,202
Long term debt payable to VUHI 148,484 159,927 86,574 93,820
Short-term borrowings 830 830 - -
Short-term borrowings from VUHI 82,929 82,929 39,419 39,419


Certain methods and assumptions must be used to estimate the fair value of
financial instruments. The fair value of the Company's other financial
instruments was estimated based on the quoted market prices for the same or
similar issues or on the current rates offered to the Company for instruments
with similar characteristics. Because of the maturity dates and variable
interest rates of short-term borrowings, its carrying amount approximates its
fair value.

Under current regulatory treatment, call premiums on reacquisition of long-term
debt are generally recovered in customer rates over the life of the refunding
issue or over a 15-year period. Accordingly, any reacquisition would not be
expected to have a material effect on the Company's financial position or
results of operations.

11. Segment Reporting

The Company has two operating segments: (1) Gas Utility Services and (2)
Electric Utility Services as defined by SFAS 131 "Disclosure About Segments of
an Enterprise and Related Information" (SFAS 131). Gas Utility Services provides
natural gas distribution and transportation services in southwestern Indiana,
including counties surrounding Evansville. Electric Utility Services provides
electricity primarily to southwestern Indiana, and includes the Company's power
generating and marketing operations. For its operations the Company uses after
tax operating income as a measure of profitability, consistent with regulatory
reporting requirements. The Company cross manages its margin, other operating
expenses, and capital expenditures as separated between Energy Delivery, which
includes the gas and electric transmission and distribution functions, and Power
Supply, which includes the power generating and marketing operations. The
Company makes decisions on finance and dividends at the corporate level.

13. Special Charges for 2001

Restructuring & Related Charges
As part of continued cost saving efforts, in June 2001, Vectren's management and
the board of directors approved a plan to restructure, primarily, its regulated
operations. The restructuring plan included the elimination of certain
administrative and supervisory positions in its utility operations and corporate
office. Charges of $4.3 million were expensed in June 2001 as a direct result of
the restructuring plan. Additional charges of $1.5 million were incurred during
the remainder of 2001 primarily for consulting fees and employee relocation
costs. In total, the Company incurred restructuring charges of $5.8 million.
These charges were comprised of $4.4 million for employee severance, related
benefits, and other employee related costs, and $1.4 million for consulting and
other fees incurred.

The $4.4 million of severance and related costs included $0.8 million of
non-cash pension costs. Restructuring expenses were incurred by the Company's
operating segments as follows: $1.0 million by the Gas Utility Services segment
and $4.8 million by the Electric Utility Services segment.

Employee severance and related costs are associated with approximately 40
employees. Employee separation benefits include severance, healthcare, and
outplacement services. During 2001, 37 employees had exited the business. The
restructuring program was completed during 2001, except for the departure of the
remaining employees impacted by the restructuring which occurred during 2002.

At the beginning of 2002, the remaining accrual related to the restructuring was
$0.2 million. Of that amount, almost all relates to structured compensation
arrangements payable through 2004. During 2003 and 2002, the accrual for
severance did not substantially change. At December 31, 2003, and 2002, the
restructuring accrual was $0.6 million and $0.9 million, respectively. The
restructuring accrual is included in Accrued liabilities.

Merger & Integration Costs
Merger and integration costs incurred for the year ended December 31, 2001,
totaled $0.6 million. Those costs related primarily to transaction costs,
severance, and other merger and acquisition integration activities. The
integration activities experienced by the Company included such things as
information system consolidation, process review and definition, organization
design and consolidation, and knowledge sharing. Merger and integration
activities resulting from the 2000 merger were completed in 2001.

14. Impact of Recently Issued Accounting Guidance

SFAS 149
In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities" (SFAS 149). SFAS 149 amends and
clarifies the accounting guidance on (1) derivative instruments (including
certain derivative instruments embedded in other contracts) and (2) hedging
activities that fall within the scope of FASB Statement No. 133 (SFAS 133),
"Accounting for Derivative Instruments and Hedging Activities." SFAS 149 amends
SFAS 133 to reflect decisions that were made (1) as part of the process
undertaken by the Derivatives Implementation Group (DIG), which necessitated
amending SFAS 133, (2) in connection with other projects dealing with financial
instruments, and (3) regarding implementation issues related to the application
of the definition of a derivative. SFAS 149 also amends certain other existing
pronouncements which will result in more consistent reporting of contracts that
are derivatives in their entirety or that contain embedded derivatives that
warrant separate accounting. SFAS 149 is effective (1) for contracts entered
into or modified after June 30, 2003, with certain exceptions and (2) for
hedging relationships designated after June 30. The guidance is to be applied
prospectively. The adoption did not have a material effect on the Company's
results of operations or financial condition.

SFAS 150
In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of Both Liabilities and Equity" (SFAS 150).
SFAS 150 requires issuers to classify as liabilities the following three types
of freestanding financial instruments: mandatorily redeemable financial
instruments, obligations to repurchase the issuer's equity shares by
transferring assets, and certain obligations to issue a variable number of
shares. SFAS 150 was effective immediately for financial instruments entered
into or modified after May 31, 2003; otherwise, the standard was effective for
all other financial instruments at the beginning of the Company's third quarter
of 2003. In October 2003, the FASB issued further guidance regarding mandatorily
redeemable stock which is effective January 1, 2004, for the Company. The
adoption of SFAS 150 on January 1, 2004, did not affect the Company's results of
operations or financial condition.

FASB Interpretation (FIN) 45
In November 2002, the FASB issued FIN 45. FIN 45 clarifies the requirements for
a guarantor's accounting for and disclosure of certain guarantees issued and
outstanding and that a guarantor is required to recognize, at the inception of a
guarantee, a liability for the fair value of the obligations it has undertaken.
The initial recognition and measurement provisions were applicable on a
prospective basis to guarantees issued or modified after December 31, 2002.
Since that date, the adoption has not had a material effect on the Company's
results of operations or financial condition.

FIN 46/46-R (Revised in December 2003)
In January 2003, the FASB issued Interpretation 46, "Consolidation of Variable
Interest Entities" (FIN 46). FIN 46 addresses consolidation by business
enterprises of variable interest entities (VIE) and significantly changes the
consolidation requirements for those entities. FIN 46 is intended to achieve
more consistent application of consolidation policies related to VIE's and thus
improves comparability between enterprises engaged in similar activities when
those activities are conducted through VIE's. In December 2003, the FASB
completed its deliberations of proposed modifications to FIN 46 and decided to
codify both the proposed modifications and other decisions previously issued
through certain FASB Staff Positions into one document that was issued as a
revision to the original Interpretation (FIN 46-R). FIN 46-R currently applies
to VIE's created after January 31, 2003, and to VIE's in which an enterprise
obtains an interest after that date. For entities created prior to January 31,
2003, FIN 46 is to be adopted no later than the end of the first interim or
annual reporting period ending after March 15, 2004. Although management is
still evaluating the impact of FIN 46 and related Staff Positions on its
financial position and results of operations, the adoption is not expected to
have a material effect.

Staff Accounting Bulletin No. 104
In December 2003, the SEC published Staff Accounting Bulletin (SAB) No. 104,
"Revenue Recognition". This SAB updates portions of the SEC staff's interpretive
guidance provided in SAB 101 and included in Topic 13 of the Codification of
Staff Accounting Bulletins. SAB 104 deletes interpretative material no longer
necessary and conforms the interpretive material retained because of
pronouncements issued by the FASB's EITF on various revenue recognition topics,
including EITF 00-21, "Revenue Arrangements with Multiple Deliverables." The
Company's adoption of the standard did not have an impact on its revenue
recognition policies.


15. Subsequent Event

On March 12, 2004, SIGECO (d/b/a Vectren Energy Delivery of Indiana, Inc.) filed
a petition with the IURC to adjust its base rates and charges for its gas
distribution business in southwestern Indiana. If the filing is approved, SIGECO
expects to increase its base (non-gas cost) rates by approximately $5.7 million
to cover the ongoing cost of operating and maintaining the approximately
3,000-mile distribution and storage system used to serve more than 110,000
customers. If finalized by the OUCC and ultimately approved by the IURC, the
agreement in principle would result in about a 5 percent increase for the
typical SIGECO residential customer who uses natural gas to heat his/her home.
The proposal will not affect the electric portion of the Company's customer
bills.

The petition only addresses "non-gas" costs, which are incurred to build,
operate and maintain the pipes, other equipment and systems that are used to
deliver gas. The petition indicates that SIGECO has reached an agreement in
principle with the OUCC regarding the proposed changes to the rates and charges.
The agreement in principle further provides for SIGECO's recovery through a
tracking mechanism of costs required to comply with a new federal law dealing
with pipeline safety.

As required by the regulatory process, SIGECO will be required to submit
information substantiating the proposed adjustment to its base rates. During the
processing of the case by the IURC, there will also be one or more public
hearings conducted regarding the proposal. The timing and ultimate outcome of
this regulatory initiative is uncertain.

ITEM 9a. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of December 31, 2003, the Company carried out an evaluation under the
supervision and with the participation of the Chief Executive Officer and Chief
Financial Officer of the effectiveness and the design and operation of the
Company's disclosure controls and procedures. Based on that evaluation, the
Chief Executive Officer and the Chief Financial Officer have concluded that the
Company's disclosure controls and procedures are effective at providing
reasonable assurance that material information relating to the Company required
to be disclosed by the Company in its filings under the Securities Exchange Act
of 1934 (Exchange Act) is brought to their attention on a timely basis.

Disclosure controls and procedures, as defined by the Exchange Act in Rules
13a-15(e) and 15d-15(e), are controls and other procedures of the Company that
are designed to ensure that information required to be disclosed by the Company
in the reports filed or submitted by it under the Exchange Act is recorded,
processed, summarized, and reported within the time periods specified in the
SEC's rules and forms. "Disclosure controls and procedures" include, without
limitation, controls and procedures designed to ensure that information required
to be disclosed by the Company in its Exchange Act reports is accumulated and
communicated to the Company's management, including its principal executive and
financial officers, as appropriate, to allow timely decisions regarding required
disclosure.

Changes in Internal Control Over Financial Reporting

During the quarter ended December 31, 2003, there have been no significant
changes to the Company's internal control over financial reporting that have
materially affected, or are reasonably likely to materially affect, the
Company's internal control over financial reporting.

Internal control over financial reporting is defined by the SEC in Final Rule:
Management's Reports on Internal Control Over Financial Reporting and
Certification of Disclosure in Exchange Act Periodic Reports. The final rule
defines internal control over financial reporting as a process designed by, or
under the supervision of, the registrant's principal executive and principal
financial officers, or persons performing similar functions, and effected by the
registrant's board of directors, management and other personnel, to provide
reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with
generally accepted accounting principles and includes those policies and
procedures that: (1) pertain to the maintenance of records that in reasonable
detail accurately and fairly reflect the transactions and dispositions of the
assets of the registrant, (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and
expenditures of the registrant are being made only in accordance with
authorizations of management and directors of the registrant, and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use or disposition of the registrant's assets that could have a
material effect on the financial statements.

(4) All Other Fees - None.

Pursuant to its charter, Vectren's Audit Committee is responsible for selecting,
approving professional fees, and overseeing the independence, qualifications and
performance of the independent auditors. The Audit Committee has adopted a
formal policy with respect to the pre-approval of audit and permissible
non-audit services provided by the independent auditors. Pre-approval is
assessed on a case-by-case basis. In assessing requests for services to be
provided by the independent auditors, the Audit committee considers whether such
services are consistent with the auditors' independence, whether the independent
auditors are likely to provide the most effective and efficient service based
upon their familiarity with Vectren, and whether the service could enhance
Vectren's ability to manage or control risk or improve audit quality. The
audit-related, tax, and other services provided by Deloitte in the last fiscal
year and related fees were approved by the Audit Committee in accordance with
this policy.
