            SOUTHERN INDIANA GAS AND ELECTRIC COMPANY
                  NOTES TO FINANCIAL STATEMENTS
                           (UNAUDITED)


1.  Organization and Nature of Operations

Southern Indiana Gas and Electric Company (SIGECO) operates as a
separate wholly owned subsidiary of Vectren Corporation (Vectren)
and provides generation, transmission, distribution and the sale
of electric power to Evansville, Indiana, and 74 other
communities, and the distribution and sale of natural gas to
Evansville, Indiana, and 64 communities in ten counties in
southwestern 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), SIGECO's former parent company. On March
31, 2000, the merger of Indiana Energy with SIGCORP and into
Vectren was consummated with a tax- free exchange of shares that
has been accounted for as a pooling-of-interests. The merger did
not affect SIGECO's preferred stock or debt securities.

2.  Basis of Presentation

The interim financial statements included in this report have
been prepared by SIGECO, without audit, as provided in the rules
and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosures normally included in
financial statements prepared in accordance with accounting
principles generally accepted in the United States have been
omitted as provided in such rules and regulations.  SIGECO
believes that the information in this report reflects all
adjustments necessary to fairly state the results of the interim
periods reported.  These financial statements and related notes
should be read in conjunction with SIGECO's audited annual
financial statements for the year ended December 31, 2000 filed
on Form 10-K.  Because of the seasonal nature of SIGECO's
operations, the results shown on a quarterly basis are not
necessarily indicative of annual results.

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 statements
and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those
estimates.

Certain reclassifications have been made to prior period
financial statements to conform with the current year
classification. These reclassifications have no impact on
previously reported net income.

3.  Merger and Integration Costs

Merger and integration costs incurred for the three and twelve
months ended March 31, 2001 were $0.4 million and $2.1 million,
respectively.  These costs relate primarily to transaction costs,
severance, and other merger and integration activities such as
signage and vehicle identification changes. Merger costs are
reflected in the financial statements of the subsidiaries in
which merger savings are expected to be realized.  The accrual
remaining for such costs at March 31, 2001 was $0.4 million.  The
continued merger integration activities will be substantially
completed in 2001.

4.  Long - Term Debt

SIGECO has $53.7 million of adjustable rate pollution control
series first mortgage bonds which could, at the election of the
bondholder, be tendered to SIGECO when the interest rates are
reset.  Prior to the latest reset on March 1, 2001, the interest
rates were reset annually, and the bonds subject to tender were
presented in the Balance Sheets as current liabilities.
Effective March 1, 2001, the bonds were reset for a five-year
period and have been classified as long-term debt.  Resulting
from the reset, the interest rate on the $31.5 million Series A
bonds increased from 4.30 % to 4.75 %, and the interest rate on
the $22.2 million Series C bonds increased from 4.45 % to 5.00 %.

5.  New Accounting Principle

In June 1998, the Financial Accounting Standards Board issued
SFAS No. 133 "Accounting for Derivative Instruments and Hedging
Activities" (SFAS 133), which requires that every derivative
instrument be recorded on the balance sheet as an asset or
liability measured at its fair value and that changes in the
derivative's fair value be recognized currently in earnings
unless specific hedge accounting criteria are met.

SFAS 133, as amended, is effective for fiscal years beginning
after June 15, 2000 and must be applied to derivative instruments
and certain derivative instruments embedded in hybrid contracts
that were issued, acquired or substantively modified after
December 31, 1998.  SIGECO has completed the process of
identifying all derivative instruments, determining fair market
values of these derivatives, designating and documenting hedge
relationships, and evaluating the effectiveness of those hedge
relationships.  As a result of the successful completion of this
process, SIGECO adopted SFAS 133 as of January 1, 2001.

SFAS 133 requires that as of the date of initial adoption, the
difference between the fair 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, as the cumulative
effect of a change in accounting principle in accordance with APB
20, "Accounting Changes."

A limited number of SIGECO's contracts are defined as derivatives
under SFAS 133.  These derivatives are forward physical contracts
for both the purchase and sale of electricity.

SIGECO uses derivative and non-derivative forward contracts in
its power marketing operations to effectively manage the
utilization of its generation capacity. Certain forward sales
contracts are used to sell the excess generation capacity of
SIGECO when demand conditions warrant this activity.  These
contracts involve the normal sale of electricity and therefore do
not require fair value accounting under SFAS 133.  Certain
forward purchase and sale contracts entered into as part of "buy-
sell" transactions with other utilities and power marketers are
derivatives but do not qualify for hedge accounting.  The mark to
market impact of these derivatives upon adoption of SFAS 133 is
reflected as part of the transition adjustment recorded to
earnings on January 1, 2001.   This cumulative impact is an
earnings gain of approximately $6.3 million ($3.9 million after
tax).

As of March 31, 2001, the fair value of power marketing
derivative contracts total $11.8 million and is included in
deferred charges, net in the Balance Sheets.  The difference
between the current market value and the market value on the date
of adoption of $5.5 million is reflected in cost of fuel and
purchased power in the Statements of Income.

6.  Contingencies

SIGECO is party to various legal proceedings arising in the
normal course of business.  In the opinion of management, with
the exception of the litigation matter related to the Clean Air
Act (See Note 7), there are no legal proceedings pending against
SIGECO that are likely to have a material adverse effect on its
financial position or results of operations.

7.  Environmental Matters

NOx SIP Call Matter
In October 1997, the United States Environmental Protection
Agency (USEPA) proposed a rulemaking that could require uniform
nitrogen oxide (NOx) emissions reductions of 85 % by utilities
and other large sources in a 22-state region spanning areas in
the Northeast, Midwest, Great Lakes, Mid-Atlantic and South.
This rule is referred to as the "NOx SIP call."  The USEPA
provided each state a proposed budget of allowed NOx emissions, a
key ingredient of ozone, requiring a significant reduction of
such emissions.  Under that budget, utilities may be required to
reduce NOx emissions to a rate of 0.15 lb/mmBtu below levels
already imposed by Phase I and Phase II of the Clean Air Act
Amendments of 1990 (the Act).

On October 27, 1998, 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).  The final
rule requires that 23 states and jurisdictions must file revised
state implementation plans (SIPs) with the USEPA by no later than
September 30, 1999, which was essentially unchanged from its
October 1997, proposed rule.  The USEPA has encouraged states to
target utility coal-fired boilers for the majority of the
reductions required, especially NOx emissions.  Northeastern
states have claimed that ozone transport from midwestern states
(including Indiana) is the primary reason for their ozone
concentration problems.  Although this premise is challenged by
others based on various air quality modeling studies, including
studies commissioned by the USEPA, the USEPA intends to
incorporate a regional control strategy to reduce ozone
transport.  The USEPA's final ruling is being litigated in the
federal courts by approximately ten midwestern states, including
Indiana.

On March 3, 2000, the United States Circuit Court of Appeals for
the District of Columbia (D.C. Court of Appeals) upheld the
USEPA's October 27, 1998 final rule requiring 23 states and the
District of Columbia to file revised SIPs with the USEPA.
Numerous petitioners, including several states, filed petitions
for rehearing with the D.C. Court of Appeals.  On June 22, 2000,
the D.C. Court of Appeals denied petition for rehearing en banc.
Following this decision, on August 30, 2000, the D.C. Court of
Appeals issued an extension of the SIP Call implementation
deadline to May 31, 2004.  On September 20, 2000, petitioners
filed a Petition of Writ of Certiori with the United States
Supreme Court requesting review of the D.C. Court of Appeals
March 3, 2000 Order, which was denied.  Therefore, SIGECO's
compliance date remains May 31, 2004.

The proposed NOx emissions budget for Indiana stipulated in the
USEPA's final ruling requires a 36 % reduction in total NOx
emissions from Indiana.  The ruling, pending finalization of
state rule making, could require SIGECO to lower its system-wide
emissions by approximately 70 %.  Depending on the level of
system-wide emissions reductions ultimately required, and the
control technology utilized to achieve the reductions, the
estimated construction costs of the control equipment could reach
$160 million, which are expected to be expended during the 2001-
2004 period, and related additional operation and maintenance
expenses could be an estimated $8 million to $10 million,
annually.

Culley Generating Station Investigation Matter
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 performance
standards should be applied to the modifications and whether the
best available control technology was, or should have been, used.
Numerous other electric utilities were, and are currently, being
investigated by the USEPA under an industry-wide review for
similar compliance.  SIGECO responded to all of the USEPA's data
requests during the investigation.  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 the 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 with the USEPA
and targeted utilities, including SIGECO, regarding potential
remedies to the USEPA's general allegations.

<PAGE> 10

On November 3, 1999, the USEPA filed a lawsuit against seven
utilities, including SIGECO.  The USEPA alleges that, beginning
in 1992, SIGECO violated the Act by: (i) making modifications to
its Culley Generating Station in Yankeetown, Indiana without
obtaining required permits; (ii) making major modifications to
the Culley Generating Station without installing the best
available emission control technology; and (iii) failing to
notify the USEPA of the modifications.  In addition, the lawsuit
alleges that the modifications to the Culley Generating Station
required SIGECO to begin complying with federal new source
performance standards.

SIGECO believes it performed only maintenance, repair and
replacement activities at the Culley Generating Station, as
allowed under the Act.  Because proper maintenance does not
require permits, application of the best available emission
control technology, notice to the USEPA, or compliance with new
source performance standards, SIGECO believes that the lawsuit is
without merit, and intends to vigorously defend the lawsuit.

The lawsuit seeks fines against SIGECO in the amount of $27,500
per day per violation.  The lawsuit does not specify the number
of days or violations the USEPA believes occurred.  The lawsuit
also seeks a court order requiring SIGECO to install the best
available emissions technology at the Culley Generating Station.
If the USEPA is successful in obtaining an order, SIGECO
estimates that it would incur capital costs of approximately $40
million to $50 million complying with the order.  In the event
that SIGECO is required to install system-wide NOx emission
control equipment, as a result of the NOx SIP call issue, the
majority of the $40 million to $50 million for best available
emissions technology at Culley Generating Station would be
included in the $160 million expenditure previously discussed.

The USEPA has also issued an administrative notice of violation
to SIGECO making the same allegations, but alleging that
violations began in 1977.

While it is possible that SIGECO could be subjected to criminal
penalties if the Culley Generating Station continues to operate
without complying with the new source performance standards and
the allegations are determined by a court to be valid, SIGECO
believes such penalties are unlikely as the USEPA and the
electric utility industry have a bonafide dispute over the proper
interpretation of the Act.  Consequently, SIGECO anticipates at
this time that the plant will continue to operate while the
matter is being decided.

Information Request
On January 23, 2001, SIGECO received an information request from
the USEPA under Section 114(a) of the Act for historical
operational information on the Warrick and A.B. Brown generating
stations.  SIGECO has provided all information requested, and
management believes that no significant issues will arise from
this request.

8.  Rate and Regulatory Matters

Commodity prices for natural gas purchases have increased
significantly, primarily due to a colder winter, increased demand
and tighter supplies.  SIGECO is allowed full recovery of such
changes in purchased gas and fuel costs for its retail customers
through commission-approved gas and fuel cost adjustment
mechanisms.

As a result of the ongoing 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 Indiana Office of Utility Consumer Counselor (OUCC) that
provides certain terms with respect to the recoverability of such
costs.  The settlement, originally approved by the IURC on August
9, 2000, has been extended by agreement through March 2002.
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.

9.  Affiliate Transactions

Certain wholly owned subsidiaries of Vectren began providing
support services to SIGECO beginning April 1, 2000. As of March
31, 2000, certain assets owned by SIGECO were contributed to a
wholly owned subsidiary of Vectren (Vectren Resources, LLC). The
contribution of assets was reflected as a reduction of common
shareholder's equity and is omitted from the Statements of Cash
Flows. Vectren Resources, LLC provides asset services to SIGECO,
the fee for which is reflected in operation and maintenance

expense in the accompanying financial statements. Services
provided include corporate-level management services, information
technology, financial, human resources, purchasing, building and
fleet services. For the three and twelve months ended March 31,
2001, amounts billed by other wholly owned subsidiaries of
Vectren to SIGECO were approximately $11.1 million and $41.1
million, respectfully.  Prior to April 1, 2000, these costs were
incurred by SIGECO directly.

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
three months ended March 31, 2001 and 2000 were $10.4 million and
$6.6 million respectively. Amounts paid for such purchases for
the twelve months ended March 31, 2001 and 2000 were $28.6
million and $22.2 million, respectively.

SIGECO also participates in a centralized cash management program
with its parent, affiliated companies and banks which permits
funding of checks as they are presented.

Amounts owed to wholly owned subsidiaries of Vectren as of March
31, 2001, March 31, 2000 and December 31, 2000 totaled $31.3
million, $6.5 million and $11.5 million, respectively, and are
included in accounts payable to affiliated company.  Amounts due
from wholly owned subsidiaries of Vectren as of March 31, 2001,
March 31, 2000 and December 31, 2000 totaled $9.9 million, $8.2
million, and $27.8 million, respectively, and are included in
accounts receivable from affiliated company.

10.  Segment Reporting

Operating segments are defined as components of an enterprise for
which separate financial information is available and evaluated
regularly by the chief operating decision makers in deciding how
to allocate resources and in the assessment of performance.

There were two operating segments of SIGECO during the reported
periods: (1) Electric Utility Services and (2) Gas Utility
Services. The Electric Utility Services segment generates,
transmits, distributes and sells electricity within primarily
southwestern Indiana and in periods of under utilized capacity,
sells excess electricity to other wholesale customers.  The Gas
Utility Services segment distributes, transports and sells
natural gas to Evansville, Indiana and 64 communities in ten
counties in southwestern Indiana.  Revenues for each segment are
principally attributable to customers in the United States.
Effective January 1, 2001, SIGECO announced the reorganization of
its utility operations into two primary business units:  Energy
Delivery and Power Supply.  During 2001, organizational alignment
will occur along with the development of management reporting
processes.  As a result, SIGECO will report segment information
as Gas Utility Services and Electric Utility Services.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
OPERATIONS AND FINANCIAL CONDITION

            SOUTHERN INDIANA GAS AND ELECTRIC COMPANY

                   Description of the Business

Southern Indiana Gas and Electric Company (SIGECO) operates as a
separate wholly owned subsidiary of Vectren Corporation (Vectren)
and provides generation, transmission, distribution and the sale
of electric power to Evansville, Indiana, and 74 other
communities, and the distribution and sale of natural gas to
Evansville, Indiana, and 64 communities in ten counties in
southwestern 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), SIGECO's former parent company. On March
31, 2000, the merger of Indiana Energy with SIGCORP and into
Vectren was consummated with a tax- free exchange of shares that
has been accounted for as a pooling-of-interests. The merger did
not affect SIGECO's preferred stock or debt securities.

                      Results of Operations

Net Income Applicable to Common Shareholder

For the three months ended March 31, 2001, net income applicable
to common shareholder was $19.3 million.  Net income applicable
to common shareholder before merger and integration costs and the
cumulative effect of the accounting change (adoption of FAS 133)
was $15.6 million, compared to net income applicable to common
shareholder before merger and integration costs for the first
quarter of 2000 of $13.0 million.  (See discussion of merger and
integration costs and cumulative effect of change in accounting
principle below.)

For the twelve months ended March 31, 2001, net income applicable
to common shareholder was $55.3 million.  Net income applicable
to common shareholder before merger and integration costs and the
cumulative effect of the accounting change (adoption of FAS 133)
was $53.2 million, compared to net income applicable to common
shareholder before merger and integration costs for the twelve
months ended March 31, 2000 of $46.5 million.

Utility Margin (Operating Revenues Less Cost of Fuel, Purchased
Power and Cost of Gas)

Electric Utility Margin
Electric Utility margin for the three months ended March 31, 2001
of $57.1 million, increased $5.8 million, or 11 %, over 2000
primarily due to a $5.5 million gain recorded to reflect certain
wholesale power marketing purchase and sale contracts at current
market values as required by Statement of Financial Accounting
Standard No. 133 "Accounting for Derivative Instruments and
Hedging Activities" (SFAS 133).

Electric Utility margin for the twelve months ended March 31,
2001 of $230.1 million, increased $15.0 million, or 7 % over 2000
primarily due to the current quarter $5.5 million gain recorded
to reflect certain wholesale power marketing purchase and sale
contracts at current market values as required by SFAS 133.  The
remaining $9.5 million increase results from increased margin
from sales to wholesale energy markets with volumes increasing 69
% over 2000, and a 5 % increase in sales to retail customers for
the period due to the impact of colder weather on retail electric
heating sales and an increasing customer base.

Total cost of fuel for electric generation and purchased power
increased $9.5 million, or 44 %, and $27.1 million, or 29 %, for
the three and twelve month periods ended March 31, 2001, compared
to the same periods in the prior year due primarily to increased
purchased power related to the greater sales to other utilities
and power marketers.

<PAGE> 14

Gas Utility Margin
Gas Utility margin for the three months ended March 31, 2001 of
$10.5 million increased $0.9 million, or 9 %, compared to 2000.
The increase is due to an 8 % increase in throughput resulting
primarily from temperatures being 16 % colder than the previous
year.  These favorable impacts were partially offset by reduced
consumption and the cost of unaccounted for gas due to much
higher gas costs (see below).

Total cost of gas sold was $41.5 million for the three months
ended March 31, 2001 compared to $19.6 million in 2000.  This
increase of $21.8 million, or 111 % is primarily due to
significantly higher average per unit purchased gas costs.  The
total average cost per dekatherm of gas purchased by SIGECO for
the three months ended March 31, 2001 was $6.74 compared to $3.86
for the same period in 2000.

Gas Utility margin for the twelve months ended March 31, 2001 of
$31.3 million increased $3.3 million, or 12 %, compared to 2000.
The increase is due to a 15 % increase in throughput resulting
primarily from temperatures being 27 % colder than the previous
year and a 2 % increase in the residential customer base.  These
favorable impacts on gas margin were partially offset by the cost
of unaccounted for gas due to higher gas costs.

Total cost of gas sold was $100.7 million for the twelve months
ended March 31, 2001 and $39.7 million in 2000.  This increase of
$61.0 million, or 153 %, compared to 2000 is primarily due to
significantly higher per unit purchased gas costs.

Commodity prices for natural gas purchases have increased
significantly, primarily due to a colder winter, increased demand
and tighter supplies.  SIGECO is allowed full recovery of such
charges in purchased gas costs from their retail customers
through commission-approved gas cost adjustment mechanisms, and
margin on gas sales should not be impacted. However, in 2001,
SIGECO has experienced and may continue to experience higher
working capital requirements, increased expenses including
unrecoverable interest costs, uncollectibles and unaccounted for
gas, and some level of price sensitive reduction in volumes sold.

Operating Expenses

Operations and Maintenance
Operations and maintenance expenses increased $2.2 million, or 10
%, for the three months ended March 31, 2001 compared to the
prior year, and operations and maintenance expenses increased
$10.6 million, or 11 % for the twelve months ended March 31,
2001.  The increases reflect primarily higher general and
administrative costs and plant and system maintenance.

Depreciation and Amortization
Depreciation and amortization decreased $0.4 million and $2.3
million, respectively, for the three and twelve months ended
March 31, 2001 compared to the prior year due to the contribution
of certain information systems and equipment to a wholly owned
subsidiary of Vectren.

Income Taxes
Federal and state income taxes increased $4.8 million and $6.3
million for the three and twelve months ended March 31,
2001,respectively, compared to the prior year due primarily to
higher pre-tax earnings, partially offset by normal effective tax
rates in 2001.  The effective tax rate for the three month period
in 2000 was higher as a result of the non-deductibility of
certain merger and integration costs.

Taxes Other Than Income Taxes
Taxes other than income taxes increased $0.4 million and $0.7
million, respectively, for the three and twelve month periods
ended March 31, 2001.  The increases result from increases in
gross receipts and property taxes.

<PAGE> 15

Merger and Integration Costs

These costs relate primarily to transaction costs, severance, and
other merger and integration activities such as signage and
vehicle identification changes.  Vectren expects to realize net
merger savings of nearly $200 million over the next ten years
from the elimination of duplicate corporate and administrative
programs and greater efficiencies in operations, business
processes and purchasing.  The continued merger integration
activities, which will contribute to the merger savings, will be
substantially completed in 2001.  Merger costs are reflected in
the financial statements of Vectren's operating subsidiaries in
which merger savings are expected to be realized.

For the three months ended March 31, 2001, merger and integration
costs totaled $0.4 million ($0.2 million after tax), compared to
$12.4 million ($9.0 million after tax) for the same period in
2000.  For the twelve months ended March 31, 2001, merger and
integration costs totaled $2.1 million ($1.8 million after tax),
compared to $12.4 million ($9.0 million after tax) for the same
period in 2000.

Other Income, Net

Other income, net increased $0.2 million and $1.4 million for the
three and twelve months ended March 31, 2001 compared to the
prior year due to increased allowance for funds used during
construction (AFUDC) resulting from increased utility plant
construction in progress.

Interest Expense

Interest expense increased by $0.5 million and $0.8 million,
respectively, for the three and twelve months ended March 31,
2001, when compared to the prior year.  The increases were due
primarily to increased working capital requirements resulting
from higher natural gas prices.

                     Other Operating Matters

New Accounting Principle and Cumulative Effect of Change in
Accounting Principle

See Note 5 in the financial statements regarding the adoption of
SFAS 133, as amended.

Realignment

Effective January 1, 2001, SIGECO announced the reorganization of
its utility operations into two primary business units:  Energy
Delivery and Power Supply.  During 2001, organizational alignment
will occur along with the development of management reporting
processes.  As a result, SIGECO will report segment information
as Gas Utility Services and Electric Utility Services.

                       Financial Condition

Environmental and Regulatory Matters

See Notes 7 and 8 in SIGECO's financial statements included in
Part I, Item 1 regarding matters affecting operations including
Clean Air Act compliance (Note 7) and purchased power costs
recovery (Note 8).

Liquidity and Capital Resources

SIGECO's capitalization objective is 40-55 % permanent
capitalization.  This objective may have varied, and will vary,
from time to time, depending on particular business opportunities
and seasonal factors that affect the company's operation.
SIGECO's common equity component was 53 %, 51 % and 52 % of total
capitalization, including current maturities of long-term debt,
at March 31, 2001, March 31, 2000 and December 31, 2000,
respectively.

<PAGE> 16

Short-term cash working capital is required primarily to finance
customer accounts receivable, unbilled utility revenues resulting
from cycle billing, gas in underground storage, prepaid gas
delivery services, capital expenditures and investments until
permanently financed.  Short-term borrowings tend to be greatest
during the summer when accounts receivable and unbilled utility
revenues related to electricity are highest and gas storage
facilities are being refilled.  However, working capital
requirements have been significantly higher during other periods
due to the higher natural gas costs.

Cash Flow from Operations
SIGECO's primary source of liquidity to fund working capital
requirements has been cash generated from operations, which
totaled approximately $46.0 million and $32.3 million for the
three months ended March 31, 2001 and 2000, respectively, and
$80.0 million and $99.5 million for the twelve months ended March
31, 2001 and 2000, respectively.

Cash flow from operations increased during the three months ended
March 31, 2001 compared to 2000 by $13.7 million due to increased
collections on accounts receivable offset by increased working
capital requirements due to higher gas costs.

Cash flow from operations decreased during the twelve months
ended March 31, 2001 compared to 2000 by $19.5 million, due to
increased working capital requirements due to higher gas costs
offset by decreased merger and integration costs.

SIGECO expects the majority of its capital expenditures and debt
security redemptions to be provided by internally generated
funds.

Financing Activities
Cash flow required for financing activities of $34.3 million for
the three months ended March 31, 2001 includes $25.3 million of
reductions in net borrowings and preferred stock and $8.8 million
common and preferred stock dividends.  This is an increase in
cash required for financing activities when compared to the three
months ended March 31, 2000 of $18.9 million.  The increase is
primarily due to increased payments on short-term borrowings from
internally generated funds in 2001.

Cash flow required for financing activities of $31.3 million for
the twelve months ended March 31, 2001 includes $4.4 million of
reductions in net borrowings and preferred stock and $29.7
million of common and preferred stock dividends.  This is a
decrease in cash requirements for financing activities of $45.7
million over the same period in the prior year due primarily to a
decrease in short-term borrowings being paid down in 2001.

SIGECO has $53.7 million of adjustable rate pollution control
series first mortgage bonds which could, at the election of the
bondholder, be tendered to SIGECO when the interest rates are
reset.  Prior to the latest reset on March 1, 2001, the interest
rates were reset annually, and the bonds subject to tender were
presented in the Balance Sheets as current liabilities.
Effective March 1, 2001, the bonds were reset for a
five-year period and have been classified as long-term debt.
Resulting from the reset, the interest rate on the $31.5 million
Series A bonds increased from 4.30 % to 4.75 %, and the interest
rate on the $22.2 million Series C bonds increased from 4.45 % to
5.00 %.

At March 31, 2001, SIGECO has approximately $74 million of short-
term borrowing capacity for use in its operations, of which
approximately $59 million is available.

SIGECO's credit rating on outstanding debt at March 31, 2001 was
A/A1.

Capital Expenditures and Other Investment Activities
Cash required for investing activities of $9.6 million and $47.2
for the three and twelve months ended March 31, 2001 is comprised
mainly of capital expenditures.  Cash requirements for investing
activities have decreased from prior year requirements primarily
due a decrease in capital expenditures for utility plant.

<PAGE> 17

New construction, normal system maintenance and improvements, and
technology investments needed to provide service to a growing
customer base will continue to require substantial expenditures.
Capital expenditures for the remainder of 2001 are estimated at
$88 million.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
         RISK

SIGECO is exposed to market risks associated with interest rates,
commodity prices and counterparty credit.   The company employs a
variety of risk management policies to monitor and control these
risks including the use of both derivative and non-derivative
financial instruments.  The company does not presently utilize
financial instruments for trading or speculative purposes.

Interest Rate Risk

SIGECO attempts to mitigate its exposure to interest rate
fluctuations through management of its short-term borrowings.  An
internal guideline to manage short-term interest rate exposure
has been established.  This guideline targets a maximum of 25% of
the company's total debt portfolio to consist of adjustable rate
bonds with a maturity of less than one year, short-term notes and
commercial paper.  However, SIGECO acknowledges that there may be
times during the business cycle that the guideline may be
exceeded.  At March 31, 2001, SIGECO's short-term debt
represented 5 % of the company's total debt portfolio, due
primarily to resetting of adjustable rate bonds for a five year
period, offset by increased working capital requirements
resulting from higher purchased gas costs and increased customer
consumption.

Market risk is estimated as the potential impact resulting from
fluctuations in interest rates on short-term borrowings,
including bank notes and lines of credit.  These instruments have
interest rates indexed to short-term market interest rates.  At
March 31, 2001, March 31, 2000 and December 31, 2000, the
combined borrowings under these facilities totaled $14.8 million,
$10.3 million and $40.2 million, respectively.  Based upon
average borrowing rates under these facilities during the three
months ended March 31, 2001 and 2000, an increase of 100 basis
points (1 %) in the rates would have increased interest expense
by $0.1 for both periods.  For the twelve months ended March 31,
2001 and 2000, an increase of 100 basis points in the rates would
have increased interest expense by $0.3 million and $0.5 million,
respectively.

Commodity Price Risk

SIGECO not currently exposed to market risks for purchases of
natural gas and electric energy for its retail customers due to
current Indiana regulations which allow for recovery of such
purchases through natural gas and fuel cost adjustment
mechanisms.

SIGECO's wholesale power marketing activities manage the
utilization of available generating capability through forward
sale contracts of electricity. Such contracts are used during
periods when SIGECO's available generating capability is expected
to exceed the demands of its retail, or native load, customers.
These activities expose the company to electricity market price
risk.  To minimize the risk related to these forward contracts,
call option contracts to hedge against the unexpected loss of its
generating capability during periods of heavy demand may be used.
SIGECO also utilizes forward physical

contracts for the wholesale purchase of generating capability to
resell to other utilities and power marketers through non-firm
"buy-resell" transactions where the sale and purchase prices of
power are concurrently set.  Management believes exposure from
these positions was not material.

Counterparty Credit Risk

SIGECO is also exposed to counterparty credit risk when a
customer or supplier defaults upon a contract to pay or deliver
the commodity. To mitigate these risks, procedures
to determine and monitor the creditworthiness of counterparties
have been established.
