1. Basis of Presentation

Nature of Operations and Basis of Consolidation. Duke Energy Indiana, Inc. (Duke Energy Indiana), an Indiana corporation organized in 1942, is a wholly-owned subsidiary of Cinergy Corp. (Cinergy). Duke Energy Indiana is a vertically integrated and regulated electric utility that provides service in north central, central, and southern Indiana. Its primary line of business is generation, transmission and distribution of electricity.

On April 3, 2006, Duke Energy Corporation (Old Duke Energy) and Cinergy merged into wholly-owned subsidiaries of Duke Energy Holding Corp. (Duke Energy HC), resulting in Duke Energy HC becoming the parent entity. In connection with the closing of the merger transactions, Duke Energy HC changed its name to Duke Energy Corporation (New Duke Energy or Duke Energy) and Old Duke Energy converted into a limited liability company named Duke Power Company LLC (subsequently renamed Duke Energy Carolinas, LLC effective October 1, 2006). As a result of the merger transactions, each outstanding share of Cinergy common stock was converted into 1.56 shares of common stock of New Duke Energy, which resulted in the issuance of approximately 313 million shares of Duke Energy common stock. Both Old Duke Energy and New Duke Energy are referred to as Duke Energy herein.

As a result of Duke Energy Indiana’s publicly held debt at the time of Duke Energy’s merger with Cinergy, push-down accounting was not required and therefore, the assets and liabilities of Duke Energy Indiana have not been recorded at their fair values as of the merger date in these consolidated financial statements.

As a result of Duke Energy’s merger with Cinergy, Duke Energy Indiana entered into a tax sharing agreement with Duke Energy, where the separate return method is used to allocate tax expenses or benefits to the subsidiaries whose investments or results of operations provide these tax expenses or benefits. The accounting for income taxes essentially represents the income taxes that Duke Energy Indiana would incur if Duke Energy Indiana were a separate company filing its own tax return as a C-Corporation. The current tax sharing agreement Duke Energy Indiana has with Duke Energy is substantially the same as the tax sharing agreement between Duke Energy Indiana and Cinergy prior to the merger.

These Consolidated Financial Statements reflect all normal recurring adjustments that are, in the opinion of management, necessary to fairly present Duke Energy Indiana’s financial position and results of operations. Amounts reported in the interim Consolidated Statements of Operations are not necessarily indicative of amounts expected for the respective annual periods due to the effects of seasonal temperature variations on energy consumption, regulatory rulings, the timing of maintenance on electric generating units, changing commodity prices, and other factors. These Consolidated Financial Statements and other information included in this quarterly report should be read in conjunction with the Consolidated Financial Statements and Notes in Duke Energy Indiana’s Form 10-K for the year ended December 31, 2006.

These Consolidated Financial Statements include, after eliminating intercompany transactions and balances, the accounts of Duke Energy Indiana and subsidiary. These Consolidated Financial Statements also reflect Duke Energy Indiana’s proportionate share of certain generation and transmission facilities.

Use of Estimates. To conform with generally accepted accounting principles (GAAP) in the United States, management makes estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and Notes. Although these estimates are based on management’s best available knowledge at the time, actual results could differ.

Reclassifications. Certain prior period amounts have been reclassified to conform to current year presentation.

Unbilled Revenue. Revenues on sales of electricity are recognized when the service is provided. Unbilled revenues are estimated by applying an average revenue per kilowatt hour for all customer classes to the number of estimated kilowatt hours delivered but not billed. The amount of unbilled revenues can vary significantly period to period as a result of factors including seasonality, weather, customer usage pattern and customer mix. Unbilled revenues, which are recorded as Receivables in Duke Energy Indiana’s Consolidated Balance Sheets at September 30, 2007 and December 31, 2006 were approximately $85 million and $80 million, respectively.

2. Assets Held for Sale

In December 2006, Duke Energy Indiana agreed to sell one unit of its Wabash River Power Station (Unit 1) to Wabash Valley Power Association, Inc. (WVPA). The price of the transaction will be based on the book value of Wabash River Power Station (Unit 1) at the time of closing, which is currently estimated to be approximately $110-$120 million. The sale is subject to the approval of the Indiana Utility Regulatory Commission (IURC), the Federal Energy Regulatory Commission (FERC), the U.S. Federal Trade Commission (FTC) and the Department of Justice (DOJ). Duke Energy Indiana has received FERC approval and was granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act by the FTC and DOJ. On January 12, 2007, Duke Energy Indiana filed a petition with the IURC requesting authority to sell Wabash River Power Station (Unit 1) to WVPA along with approval of the Operation and Maintenance Agreement and the Facilities Operations and Services Agreement associated with the sale. On May 30, 2007, Duke Energy Indiana submitted to the IURC a Settlement Agreement between Duke Energy Indiana, WVPA and the Indiana Office of Utility Consumer Counselor (OUCC). The Settlement Agreement provides for the transfer of Wabash River Power Station (Unit 1) to WVPA and approval of Duke Energy Indiana’s proposed ratemaking and accounting treatment. The IURC approved the sale in the third quarter of 2007.

Under these agreements Duke Energy Indiana will provide to WVPA certain operation and maintenance services for Wabash River Power Station (Unit 1) and WVPA’s coal gasification facility. The fees received from these agreements will be treated as revenues for ratemaking purposes and thus are expected to benefit Duke Energy Indiana’s customers. In August 2005, Duke Energy Indiana purchased the Wheatland Generating Station to replace the firm capacity to be transferred to WVPA as a result of the sale of Wabash River Power Station (Unit 1) and will replace Wabash River Power Station (Unit 1) in cost of service to Duke Energy Indiana’s electric customers.

Duke Energy Indiana does not anticipate recognizing a material gain or loss on this transaction and expects this transaction to close around the end of 2007. The assets and liabilities of the Wabash River Power Station (Unit 1) are separately disclosed on the Consolidated Balance Sheets as Assets held for sale and Liabilities associated with assets held for sale.

3. Preferred Stock

In May 2006, Duke Energy Indiana redeemed all outstanding shares of its $3.7 million notional amount 3.5% Cumulative Preferred Stock, its $3.9 million notional amount 4.32% Cumulative Preferred Stock, and its $3.7 million notional amount 4.16% Cumulative Preferred Stock at par, plus accrued and unpaid dividends.

4. Inventory

Inventory consists primarily of coal for use in electric generation and materials and supplies. Inventory is recorded primarily using the average cost method.

	September 30, 2007		December 31, 2006
	(in millions)
Fuel for use in electric generation	$	82	$	81
Materials and supplies		61		58
Total Inventory	$	143	$	139

5. Debt and Credit Facilities

Duke Energy Indiana receives support for its short-term borrowing needs through its participation with Duke Energy and other Duke Energy subsidiaries in a money pool arrangement, which allows Duke Energy Indiana to better manage its cash and working capital requirements. Under this arrangement, those companies with short-term funds may provide short-term loans to affiliates participating under this arrangement. Prior to the merger, Duke Energy Indiana participated in a similar money pool arrangement with Cinergy and other Cinergy subsidiaries. As of September 30, 2007, Duke Energy Indiana was in a payable position of $17 million classified within Notes payable in the accompanying Consolidated Balance Sheets. As of December 31, 2006, Duke Energy Indiana was in a receivable position of $120 million classified within Receivables in the accompanying Consolidated Balance Sheets. The change in the money pool for the nine months ended September 30, 2007 is reflected as a $120 million cash inflow in Notes due from affiliate, net within Net cash

(Unaudited)

used in investing activities on the Consolidated Statements of Cash Flows and a $17 million cash inflow in Notes payable within Net cash provided by (used in) financing activities on the Consolidated Statements of Cash Flows. The change in the money pool for the nine months ended September 30, 2006 is reflected as a $206 million cash outflow in Notes payable within Net cash provided by (used in) financing activities on the Consolidated Statements of Cash Flows.

In October 2007, Duke Energy Indiana had approximately $265 million of debt which matured and was subsequently repaid, principally from short-term borrowings and cash from operations.

In October 2007, Duke Energy and certain of its subsidiaries filed a registration statement (Form S-3) with the Securities and Exchange Commission (SEC). Under this Form S-3, which is uncapped, Duke Energy and certain of its subsidiaries, including Duke Energy Indiana, may issue debt and other securities in the future at amounts, prices and with terms to be determined at the time of future offerings.

Available Credit Facilities and Restrictive Debt Covenants. In June 2007, Duke Energy closed on the syndication of an amended and restated credit facility, replacing the existing credit facilities totaling $2.65 billion with a 5-year, $2.65 billion master credit facility. Duke Energy Indiana has a borrowing sub limit of $400 million under the master credit facility. Concurrent with the syndication of the master credit facility, Duke Energy established a new $1.5 billion commercial paper program at Duke Energy and terminated Cinergy’s previously existing commercial paper program.

The issuance of commercial paper, letters of credit and other borrowings reduces the amount available under the credit facility.

Duke Energy’s credit agreement contains various financial and other covenants, including, but not limited to, a covenant regarding the debt-to-total capitalization ratio at Duke Energy and Duke Energy Indiana to not exceed 65%. Duke Energy Indiana’s debt agreements also contain various financial and other covenants. Failure to meet these covenants beyond applicable grace periods could result in accelerated due dates and/or termination of the agreements. As of September 30, 2007, Duke Energy and Duke Energy Indiana were in compliance with these covenants. In addition, some credit agreements may allow for acceleration of payments or termination of the agreements due to nonpayment, or the acceleration of other significant indebtedness of the borrower or some of its subsidiaries. None of the debt or credit agreements contain material adverse change clauses.

As of September 30, 2007 and December 31, 2006, approximately $186 million of certain pollution control bonds, which are short-term obligations by nature, are classified as Long-term Debt on the Consolidated Balance Sheets due to Duke Energy Indiana’s intent and ability to utilize such borrowings as long-term financing. Duke Energy’s credit facilities with non-cancelable terms in excess of one year as of the balance sheet date give Duke Energy Indiana the ability to refinance these short-term obligations on a long-term basis.

6. Employee Benefit Obligations

Duke Energy Indiana participates in pension and other postretirement benefit plans sponsored by Cinergy. Cinergy’s qualified defined benefit pension plans cover substantially all United States employees meeting certain minimum age and service requirements. Funding for the qualified defined benefit pension plans is based on actuarially determined contributions, the maximum of which is generally the amount deductible for tax purposes and the minimum being that required by the Employee Retirement Income Security Act of 1974, as amended. The pension plans’ assets consist of investments in equity and debt securities. In addition, Cinergy sponsors non-qualified pension plans (plans that do not meet the criteria for certain tax benefits) that cover officers, certain other key employees, and non-employee directors. Cinergy also provides certain health care and life insurance benefits to retired employees and their eligible dependents. These benefits are subject to minimum age and service requirements. The health care benefits include medical coverage, dental coverage, and prescription drug coverage and are subject to certain limitations, such as deductibles and co-payments.

Duke Energy’s policy is to fund amounts for its U.S. retirement plans on an actuarial basis to provide assets sufficient to meet benefit payments to be paid to plan participants. During the nine months ended September 30, 2007, Duke Energy made qualified pension benefit contributions of $350 million to the legacy Cinergy qualified pension benefit plans, of which approximately $92 million represents contributions made by Duke Energy Indiana. During the nine months ended September 30, 2006, Duke Energy made qualified pension benefit contributions of approximately $124 million to the legacy Cinergy qualified pension benefit plans, of which approximately $24 million represents contributions made by Duke Energy Indiana. During the three and nine months ended September 30, 2007, Duke Energy contributed approximately $32 million to the legacy Cinergy other post-retirement plans, of which approximately $14 million

10

PART I

DUKE ENERGY INDIANA, INC.

Notes to Consolidated Financial Statements—(Continued)

(Unaudited)

represents contributions made by Duke Energy Indiana. Duke Energy does not anticipate making any additional contributions to its legacy Cinergy retirement plans during the remainder of 2007.

Duke Energy Indiana’s net periodic benefit costs as allocated by Cinergy were as follows:

	Three Months Ended September 30				Nine Months Ended September 30
	2007		2006		2007		2006
	(in millions)
Qualified Pension Benefits	$	4	$	6	$	14	$	17
Non-Qualified Pension		1		1		1		1
Other Postretirement		2		6		14		16

Upon consummation of the merger with Duke Energy, all defined benefit pension and other postretirement plan obligations were remeasured. While push-down accounting did not apply to Duke Energy Indiana, GAAP requires that the most recent measurement of plan obligations be used if a remeasurement has occurred. Accordingly, Cinergy updated the assumptions used to determine their accrued benefit obligations and prospective net periodic benefit cost to be allocated to Duke Energy Indiana as a result of the plan being remeasured by Duke Energy in connection with the merger on April 3, 2006.

See Note 12 for a discussion of the effect of adoption of Statement of Financial Accounting Standards (SFAS) No. 158, “Employer’s Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of Financial Accounting Standards Board (FASB) Statements No. 87, 88, 106, and 132(R)” (SFAS No. 158). Also, refer to Note 11 for a discussion of the amounts in the Consolidated Balance Sheets related to allocated accrued pension and other postretirement benefit obligations from Cinergy.

7. Intangibles

The carrying amount and accumulated amortization of intangible assets are as follows:

	September 30, 2007			December 31, 2006
	(in millions)
Emission allowances	$	63		$	77
Gas, coal, and power contracts		24			24
Total gross carrying amount		87			101
Accumulated amortization—gas, coal, and power contracts		(5	)		(4	)
Total intangible assets, net	$	82		$	97

The carrying value of emission allowances sold or consumed during the three and nine months ended September 30, 2007 were $25 million and $72 million, respectively. The carrying value of emission allowances sold or consumed during the three and nine months ended September 30, 2006 were $46 million and $113 million, respectively.

Amortization expense for intangible assets for the nine months ended September 30, 2007 and 2006 was approximately $1 million and $2 million, respectively. Amortization expense for intangible assets for the three months ended September 30, 2007 and 2006 was immaterial.

8. Business Segment

Duke Energy Indiana has one business unit, Franchised Electric, which is considered a reportable business segment under SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information.” Duke Energy Indiana’s chief operating decision maker regularly reviews financial information about the business unit in deciding how to allocate resources and evaluate performance. There is no aggregation within Duke Energy Indiana’s defined business segment.

The remainder of Duke Energy Indiana’s operations are presented as “Other.” While it is not considered a business segment, Other primarily includes certain allocated governance costs (see Note 11).

(Unaudited)

Accounting policies for Duke Energy Indiana’s segment are the same as those described in the Notes to the Consolidated Financial Statements in Duke Energy Indiana’s Annual Report on Form 10-K for the year ended December 31, 2006. Management evaluates segment performance based on earnings before interest and taxes from continuing operations (EBIT).

On a segment basis, EBIT represents all profits from continuing operations (both operating and non-operating and excluding corporate governance costs) before deducting interest and taxes. Cash, cash equivalents, and short-term investments are managed centrally by Cinergy and Duke Energy, so the interest and dividend income on those balances are excluded from the segment’s EBIT.

9. Regulatory Matters

Regulatory Merger Approvals. As discussed in Note 1, on April 3, 2006, the merger between Duke Energy and Cinergy was consummated to create a newly formed company, Duke Energy Holding Corp. (subsequently renamed Duke Energy Corporation). While the merger itself was not subject to approval by the IURC, the IURC approved certain affiliate agreements in connection with the merger subject to certain conditions. Key elements of these conditions include:

• The IURC required that Duke Energy Indiana provide a rate reduction of $40 million to its customers over a one year period and $5 million over a five year period for low-income energy assistance and clean coal technology. In April 2006, Citizens Action Coalition of Indiana, Inc. (CAC), an intervenor in the merger proceeding, filed a Verified Petition for Rehearing and Reconsideration claiming that Duke Energy Indiana should be ordered to provide an additional $5 million in rate reduction to customers to be consistent with the terms of the North Carolina Utilities Commission’s order approving the merger. In May 2006, the IURC denied the petition for rehearing and reconsideration. As of April 30, 2007, Duke Energy Indiana had completed its merger related reductions and filed a notice with the IURC to terminate the merger credit rider. Approximately $13 million of the rate reduction was passed through to customers during 2007. Approximately $12 million and $17 million of the rate reduction was passed through to customers during the three and nine months ended September 30, 2006, respectively.

• The FERC approved the merger without conditions.

Rate Related Information. The IURC approves rates for retail electric sales within Indiana. The FERC approves rates for electric sales to wholesale customers served under cost-based rates.

Energy Efficiency. In October 2007, Duke Energy Indiana filed its petition with the IURC requesting approval of an alternative regulatory plan to increase its energy efficiency efforts in the state. Duke Energy Indiana seeks approval of a plan that will be available to all customer groups and will compensate Duke Energy Indiana for verified reductions in energy usage. Under the plan, customers would pay for energy efficiency programs through an energy efficiency rider that would be included in their power bill and adjusted annually through a proceeding before the IURC. The energy efficiency rider will be based on the avoided cost of generation not needed as a result of the success of Duke Energy Indiana’s energy efficiency programs. The IURC is expected to consider the petition in a hearing sometime in 2008.

Other. In August 2005, Duke Energy Indiana filed an application with the IURC for approval of study and preconstruction costs related to the joint development of an Integrated Gasification Combined Cycle (IGCC) project with Southern Indiana Gas and Electric Company d/b/a Vectren Energy Delivery of Indiana, Inc. (Vectren). Duke Energy Indiana and Vectren reached a Settlement Agreement with the OUCC providing for the recovery of such costs if the IGCC project is approved and constructed and for the partial recovery of such costs if the IGCC project does not go forward. The IURC issued an order on July 26, 2006 approving the Settlement Agreement in its entirety.

On September 7, 2006, Duke Energy Indiana and Vectren filed a joint petition with the IURC seeking Certificates of Public Convenience and Necessity (CPCN) for the construction of a 630 megawatt (MW) IGCC power plant at Duke Energy Indiana’s Edwardsport Generating Station in Knox County, Indiana. The petition describes the applicants’ need for additional base-load generating capacity and requests timely recovery of all construction and operating costs related to the proposed generating station, including financing costs, together with certain incentive ratemaking treatment. Duke Energy Indiana and Vectren filed their cases in chief with the IURC on October 24, 2006. Duke Energy Indiana’s estimated costs for the potential IGCC project have increased. Duke Energy Indiana’s publicly filed testimony with the IURC states that industry (EPRI) total capital requirement estimates for a facility of this type and size are now in the range of $1.6 billion to $2.1 billion (including escalation to 2011 and owners’ specific site costs). In April 2007, Duke Energy Indiana and Vectren filed a Front End Engineering and Design (FEED) Study Report which included an updated estimated cost for the IGCC project of approximately $2 billion (including allowance for funds during construction). An evidentiary hearing was held June 18-22, 2007 and a public field hearing was held on August 29, 2007. An order is expected in the fourth quarter 2007. In August 2007, Vectren withdrew its participation in the IGCC plant. Duke Energy Indiana is currently exploring its options, including assuming 100% of the plant capacity. Absent identification of an alternative joint owner, Duke Energy Indiana would own 100% of the IGCC plant capacity.

Duke Energy Indiana recovers its actual fuel costs quarterly through a rate adjustment mechanism. In two recent fuel clause proceedings, certain industrial customers and the CAC have intervened and sub-dockets have been established to address issues raised by the OUCC and the intervenors concerning the allocation of fuel costs between native load customers and non-native load sales, the reasonableness of various Midwest Independent Transmission System Operator (Midwest ISO) costs for which Duke Energy Indiana has sought recovery and Duke Energy Indiana’s recovery of costs associated with certain power hedging activities. Duke Energy Indiana is defending its practices, its costs, and the allocation of such costs. A hearing was conducted in the first proceeding dealing with the allocation of fuel costs and Midwest ISO costs on September 20, 2006. The IURC issued an Order on September 13, 2007 approving of Duke Energy Indiana’s practices and removing the subject to refund provisions, except for one outstanding issue. The IURC required Duke Energy Indiana to file a compliance report outlining its further analysis and quantification of the effects of not routinely designating its coal-fired units as “must-run” in the initial months of the Midwest ISO Day 2 markets. Duke Energy Indiana plans to file the compliance report in the fourth quarter of 2007 and the impact is not expected to be material. An evidentiary hearing in the second power hedging proceeding was held in June 2007 and a decision is expected in the fourth quarter 2007. The IURC has authorized Duke Energy Indiana to collect through rates the costs which it sought recovery in the two sub-docket proceedings, subject to refund pending the outcome of these proceedings. Duke Energy Indiana cannot predict the outcome of these proceedings but does not expect the outcome to be material to its consolidated results of operations, cash flows or financial position.

FERC Issues Electric Reliability Standards. Consistent with reliability provisions of the Energy Policy Act of 2005, on July 20, 2006, FERC issued its Final Rule certifying the North American Electric Reliability Council (NERC) as the Electric Reliability Organization. NERC has filed over 100 proposed reliability standards with FERC. On March 16, 2007, FERC issued a final rule establishing mandatory, enforceable reliability standards for the nation’s bulk power system. In the final rule, FERC approved 83 of the 107 mandatory reliability standards submitted by the NERC and compliance with these standards became mandatory on June 18, 2007. FERC will consider the remaining 24 proposed standards for approval once the necessary criteria and procedures are submitted. In the interim, compliance with these 24 standards is expected to continue on a voluntary basis as good utility practice. Duke Energy Indiana does not believe that the issuance of these standards will have a material impact on its consolidated results of operations, cash flows, or financial position.

10. Commitments and Contingencies

Environmental

Duke Energy Indiana is subject to federal, state and local regulations regarding air and water quality, hazardous and solid waste disposal and other environmental matters. These regulations can be changed from time to time, imposing new obligations on Duke Energy Indiana.

Remediation activities. Duke Energy Indiana is responsible for environmental remediation at various contaminated sites. These include some properties that are part of ongoing Duke Energy Indiana operations, sites formerly owned or used by Duke Energy Indiana entities, and sites owned by third parties. Remediation typically involves management of contaminated soils and may involve groundwater remediation. Managed in conjunction with relevant federal, state and local agencies, activities vary with site conditions and locations, remedial requirements, complexity and sharing of responsibility. If remediation activities involve statutory joint and several liability provisions, strict liability, or cost recovery or contribution actions, Duke Energy Indiana could potentially be held responsible for contamination caused by other parties. In some instances, Duke Energy Indiana may share liability associated with contamination with other potentially responsible parties, and may also benefit from insurance policies or contractual indemnities that cover some or all cleanup costs. All of these sites generally are managed in the normal course of business or affiliate operations. Duke Energy Indiana believes that completion or resolution of these matters will have no material adverse effect on its consolidated results of operations, cash flows or financial position.

Clean Water Act 316(b). The U.S. Environmental Protection Agency (EPA) finalized its cooling water intake structures rule in July 2004. The rule established aquatic protection requirements for existing facilities that withdraw 50 million gallons or more of water per day from rivers, streams, lakes, reservoirs, estuaries, oceans, or other U.S. waters for cooling purposes. Three out of five coal-fired generating facilities in which Duke Energy Indiana is either a whole or partial owner are affected sources under that rule. On January 25, 2007, the U.S. Court of Appeals for the Second Circuit issued its opinion in Riverkeeper, Inc. v. EPA, Nos. 04-6692-ag(L) et. al. (2d Cir. 2007) remanding most aspects of EPA’s rule back to the agency. The court effectively disallowed those portions of the rule most favorable to industry, and the decision creates a great deal of uncertainty regarding future requirements and their timing. Duke Energy Indiana is still

14

PART I

DUKE ENERGY INDIANA, INC.

Notes to Consolidated Financial Statements—(Continued)

(Unaudited)

unable to estimate costs to comply with the EPA’s rule, although it is expected that costs will increase as a result of the court’s decision. The magnitude of any such increase cannot be estimated at this time.

Clean Air Mercury Rule (CAMR) and Clean Air Interstate Rule (CAIR). The EPA finalized its CAMR and CAIR in May 2005. The CAMR limits total annual mercury emissions from coal-fired power plants across the United States through a two-phased cap-and-trade program. Phase 1 begins in 2010 and Phase 2 begins in 2018. The CAIR limits total annual and summertime nitrogen oxides (NO_X) emissions and annual sulfur dioxide (SO₂) emissions from electric generating facilities across the Eastern United States through a two-phased cap-and-trade program. Phase 1 begins in 2009 for NO_X and in 2010 for SO₂. Phase 2 begins in 2015 for both NO_X and SO₂.

Duke Energy Indiana currently estimates that it will spend approximately $395 million between 2007 and 2011 to comply with Phase 1 of CAMR and CAIR. Duke Energy Indiana estimates its CAIR/CAMR Phase 2 compliance costs of approximately $450 million over the period 2007-2016, and is currently unable to estimate the cost of complying with Phase 2 of CAMR beyond 2016. The IURC issued an order in 2006 granting Duke Energy Indiana approximately $1.07 billion in rate recovery to cover its estimated Phase 1 compliance costs of CAIR/CAMR in Indiana. Duke Energy Indiana believes all costs determined to be prudently incurred to comply with such rules will be recovered through rates approved by the IURC.

Coal Combustion Product (CCP) Management. Duke Energy Indiana currently estimates that it will spend approximately $65 million over the period 2007-2012 to install synthetic caps and liners at existing and new CCP landfills and to convert CCP handling systems from wet to dry systems.

Extended Environmental Activities and Accruals. Included in Other Deferred Credits and Other Liabilities on the Consolidated Balance Sheets were total accruals related to extended environmental-related activities of approximately $11 million and $12 million as of September 30, 2007 and December 31, 2006, respectively. These accruals represent Duke Energy Indiana’s provisions for costs associated with remediation activities at some of its current and former sites, as well as other relevant environmental contingent liabilities. Duke Energy Indiana believes that completion or resolution of these matters will have no material impact on its consolidated results of operations, cash flows or financial position.

Litigation

New Source Review (NSR). In 1999-2000, the U.S. Justice Department, acting on behalf of the EPA, filed a number of complaints and notices of violation against multiple utilities across the country for alleged violations of the NSR provisions of the Clean Air Act (CAA). Generally, the government alleges that projects performed at various coal-fired units were major modifications, as defined in the CAA, and that the utilities violated the CAA when they undertook those projects without obtaining permits and installing the best available emission controls for SO₂, NO_X and particulate matter. The complaints seek injunctive relief to require installation of pollution control technology on allegedly violating generating units, and unspecified civil penalties in amounts of up to $27,500 per day for each violation. A number of Duke Energy Indiana’s plants have been subject to these allegations. Duke Energy Indiana asserts that there were no CAA violations because the applicable regulations do not require permitting in cases where the projects undertaken are “routine” or otherwise do not result in a net increase in emissions.

In November 1999, the United States brought a lawsuit in the United States Federal District Court for the Southern District of Indiana against Duke Energy Indiana alleging violations of the CAA at Duke Energy Indiana’s Cayuga, Gallagher, Wabash River, and Gibson Stations. The lawsuit alleges that Duke Energy Indiana violated the CAA by not obtaining Prevention of Significant Deterioration, Non-Attainment New Source Review and Indiana’s State Implementation Plan permits for 13 projects undertaken at those plants. Three northeast states and two environmental groups have intervened in the case. In June 2007, the trial court ruled, as a matter of law, that 5 of the 13 projects do not qualify for the “routine” exception in the regulations. The court ruled further that the defendants had “fair notice” of the EPA’s interpretation of the applicable regulations. The defendants have filed motions for reconsideration of the trial court’s rulings. A jury trial has been set to commence on May 5, 2008.

It is not possible to predict with certainty whether Duke Energy Indiana will incur any liability or to estimate the damages, if any, that Duke Energy Indiana might incur in connection with these matters.

Section 126 Petitions. In March 2004, the state of North Carolina filed a petition under Section 126 of the CAA in which it alleges that sources in 13 upwind states, including Indiana, significantly contribute to North Carolina’s non-attainment with certain ambient air quality standards. In August 2005, the EPA issued a proposed response to the petition. The EPA proposed to deny the ozone portion of the

15

PART I

DUKE ENERGY INDIANA, INC.

Notes to Consolidated Financial Statements—(Continued)

(Unaudited)

petition based upon a lack of contribution to air quality by the named states. The EPA also proposed to deny the particulate matter portion of the petition based upon the CAIR Federal Implementation Plan (FIP) that would address the air quality concerns from neighboring states. On April 28, 2006, the EPA denied North Carolina’s petition based upon the final CAIR FIP described above. North Carolina has filed a legal challenge to the EPA’s denial.

Carbon Dioxide (CO₂) Litigation. In July 2004, the states of Connecticut, New York, California, Iowa, New Jersey, Rhode Island, Vermont, Wisconsin, and the City of New York brought a lawsuit in the United States District Court for the Southern District of New York against Cinergy, American Electric Power Company, Inc., American Electric Power Service Corporation, The Southern Company, Tennessee Valley Authority, and Xcel Energy Inc. A similar lawsuit was filed in the United States District Court for the Southern District of New York against the same companies by Open Space Institute, Inc., Open Space Conservancy, Inc., and The Audubon Society of New Hampshire. These lawsuits allege that the defendants’ emissions of CO₂ from the combustion of fossil fuels at electric generating facilities contribute to global warming and amount to a public nuisance. The complaints also allege that the defendants could generate the same amount of electricity while emitting significantly less CO₂. The plaintiffs are seeking an injunction requiring each defendant to cap its CO₂ emissions and then reduce them by a specified percentage each year for at least a decade. In September 2005, the District Court granted the defendants’ motion to dismiss the lawsuit. The plaintiffs have appealed this ruling to the Second Circuit Court of Appeals. Oral argument was held before the Second Circuit Court of Appeals on June 7, 2006. It is not possible to predict with certainty whether Duke Energy Indiana will incur any liability or to estimate the damages, if any, that Duke Energy Indiana might incur in connection with this matter.

Manufactured Gas Plant (MGP) Sites. Coal tar residues, related hydrocarbons, and various metals have been found in at least 23 sites that Duke Energy Indiana or its predecessors previously owned and sold in a series of transactions with Northern Indiana Public Service Company (NIPSCO) and Indiana Gas Company, Inc. (IGC). The 23 sites are in the process of being studied and will be remediated, if necessary. In 1998 NIPSCO, IGC, and Duke Energy Indiana entered into Site Participation and Cost Sharing Agreements to allocate liability and responsibilities among them. Thus far, Duke Energy Indiana has primary responsibility for investigating, monitoring, and, if necessary, remediating nine of these sites. In December 2003, Duke Energy Indiana entered into a voluntary remediation plan with the state of Indiana, providing a formal framework for the investigation and cleanup of the nine sites. The Indiana Department of Environmental Management oversees investigation and cleanup of all of these sites. In 2007, Duke Energy Indiana purchased four parcels of property adjacent to one of the MGP sites because of evidence of migration of groundwater contamination.

In April 1998, Duke Energy Indiana filed suit in Hendricks County in the state of Indiana against its general liability insurance carriers. Duke Energy Indiana sought a declaratory judgment to obligate its insurance carriers to (1) defend MGP claims against Duke Energy Indiana and compensate Duke Energy Indiana for its costs of investigating, preventing, mitigating, and remediating damage to property and paying claims related to MGP sites; or (2) pay Duke Energy Indiana’s cost of defense. Duke Energy Indiana settled, in principle, its claims with all but one of the insurance carriers in January 2005 prior to commencement of the trial. With respect to the lone insurance carrier, a jury returned a verdict against Duke Energy Indiana in February 2005 on 6 of the 23 sites. Duke Energy Indiana appealed this decision, which was affirmed by the Indiana Court of Appeals. In September 2006, the Indiana Supreme Court declined to accept the appeal. Duke Energy Indiana is evaluating the impact of this decision.

Duke Energy Indiana has accrued costs related to investigation, remediation, and groundwater monitoring for those sites where such costs are probable and can be reasonably estimated. Duke Energy Indiana will continue to investigate and remediate the sites as outlined in the voluntary remediation plan. As additional facts become known and investigation is completed, Duke Energy Indiana will assess whether the likelihood of incurring additional costs becomes probable. Until all investigation and remediation is complete, Duke Energy Indiana is unable to determine the overall impact on its consolidated financial position, cash flows or results of operations.

Dunavan Waste Superfund Site. In July and October 2005, Duke Energy Indiana received notices from the EPA that it has been identified as a de minimus potentially responsible party under the Comprehensive Environmental Response, Compensation, and Liability Act at the Dunavan Waste Oil Site in Oakwood, Vermilion County, Illinois. At this time, Duke Energy Indiana does not have any further information regarding the scope of potential liability associated with this matter.

Ontario Canada Lawsuit. Duke Energy Indiana understands that a class action lawsuit was filed in Superior Court in Ontario, Canada on July 3, 2005 against Duke Energy Indiana and approximately 20 other utility and power generation companies alleging various claims relating to environmental emissions from coal-fired power generation facilities in the United States and Canada and damages of approximately $50 billion, with continuing damages in the amount of approximately $4 billion annually. Duke Energy Indiana understands that the

16

PART I

DUKE ENERGY INDIANA, INC.

Notes to Consolidated Financial Statements—(Continued)

(Unaudited)

lawsuit also claims entitlement to punitive and exemplary damages in the amount of $1 billion. Duke Energy Indiana had not been served in this lawsuit by the deadline of July 3, 2007. However, if served, Duke Energy Indiana intends to defend this lawsuit vigorously in court. At this time, Duke Energy Indiana is not able to predict whether resolution of this matter would have a material effect on its consolidated financial position, cash flows or results of operations.

Hurricane Katrina Lawsuit. In April 2006, Cinergy was named in the third amended complaint of a purported class action lawsuit filed in the United States District Court for the Southern District of Mississippi. Plaintiffs claim that Cinergy, along with numerous other utilities, oil companies, coal companies and chemical companies, are liable for damages relating to losses suffered by victims of Hurricane Katrina. Plaintiffs claim that defendants’ greenhouse gas emissions contributed to the frequency and intensity of storms such as Hurricane Katrina. In October 2006, Cinergy was served with this lawsuit. On August 30, 2007, the court dismissed the case. The plaintiffs have filed their notice of appeal to the Fifth Circuit Court of Appeals. It is not possible to predict with certainty whether Duke Energy Indiana will incur any liability or to estimate the damages, if any, that Duke Energy Indiana might incur in connection with this matter.

Asbestos-related Injuries and Damages Claims. Duke Energy Indiana has also been named as a defendant or co-defendant in lawsuits related to asbestos at its electric generating stations. The impact on Duke Energy Indiana’s results of operations, cash flows, or financial position of these cases to date has not been material. Based on estimates under varying assumptions, concerning uncertainties, such as, among others: (i) the number of contractors potentially exposed to asbestos during construction or maintenance of Duke Energy Indiana’s generating plants; (ii) the possible incidence of various illnesses among exposed workers, and (iii) the potential settlement costs without federal or other legislation that addresses asbestos tort actions, Duke Energy Indiana estimates that the range of reasonably possible exposure in existing and future suits over the foreseeable future is not material. This estimated range of exposure may change as additional settlements occur and claims are made and more case law is established.

Other Litigation and Legal Proceedings. Duke Energy Indiana is involved in other legal, tax and regulatory proceedings arising in the ordinary course of business, some of which involve substantial amounts. Duke Energy Indiana believes that the final disposition of these proceedings will not have a material adverse effect on its consolidated results of operations, cash flows or financial position.

Duke Energy Indiana has exposure to certain legal matters that are described herein. As of September 30, 2007 and December 31, 2006, Duke Energy Indiana has recorded immaterial reserves for these proceedings and exposures. Duke Energy Indiana expenses legal costs related to the defense of loss contingencies as incurred.

Other Commitments and Contingencies

Other. Duke Energy Indiana enters into various fixed-price, non-cancelable commitments to purchase or sell power (tolling arrangements or power purchase contracts) that may or may not be recognized on the Consolidated Balance Sheets.

The recognition and disclosure provisions require an employer to (1) recognize the funded status of a benefit plan— measured as the difference between plan assets at fair value and the benefit obligation—in its statement of financial position, (2) recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost, and (3) disclose in the notes to financial statements certain additional information. SFAS No. 158 does not change the amounts recognized in the income statement as net periodic benefit cost. Duke Energy Indiana recognized the funded status of its defined benefit pension and other postretirement plans and provided the required additional disclosures as of December 31, 2006. The adoption of SFAS No. 158 recognition and disclosure provisions resulted in an increase in total assets of approximately $276 million (consisting of an increase in regulatory assets) and an increase in total liabilities of approximately $276 million as of December 31, 2006.

Under the measurement date requirements of SFAS No. 158, an employer is required to measure defined benefit plan assets and obligations as of the date of the employer’s fiscal year-end statement of financial position (with limited exceptions). Historically, Duke Energy Indiana has measured its plan assets and obligations up to three months prior to the fiscal year-end, as allowed under the authoritative accounting literature. Duke Energy Indiana adopted the change in measurement date effective January 1, 2007 by remeasuring plan assets and benefit obligations as of that date, pursuant to the transition requirements of SFAS No. 158. Net periodic benefit cost of approximately $3 million for the three-month period between September 30, 2006 and December 31, 2006 was recognized, net of tax, as a separate adjustment of retained earnings as of January 1, 2007. Additionally, in the first quarter of 2007, the changes in plan assets and plan obligations between the September 30, 2006 and December 31, 2006 measurement dates not related to net periodic benefit cost was required to be recognized, net of tax, as a separate adjustment of the opening balance of regulatory assets. This adjustment was not material. During the second quarter of 2007, Duke Energy Indiana completed these calculations. The finalization of these actuarial calculations resulted in an immaterial adjustment to regulatory assets.

The adoption of SFAS No. 158 did not have a material impact on Duke Energy Indiana’s consolidated results of operations or cash flows.

Staff Accounting Bulletin (SAB) No. 108, “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements” (SAB No. 108). In September 2006 the Securities and Exchange Commission (SEC) issued SAB No. 108, which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. Traditionally, there have been two widely-recognized approaches for quantifying the effects of financial statement misstatements. The income statement approach focuses primarily on the impact of a misstatement on the income statement—including the reversing effect of prior year misstatements—but its use can lead to the accumulation of misstatements in the balance sheet. The balance sheet approach, on the other hand, focuses primarily on the effect of correcting the period-end balance sheet with less emphasis on the reversing effects of prior year errors on the income statement. The SEC staff believes that registrants should quantify errors using both a balance sheet and an income statement approach (a “dual approach”) and evaluate whether either approach results in quantifying a misstatement that, when all relevant quantitative and qualitative factors are considered, is material.

SAB No. 108 was effective for Duke Energy Indiana’s year ending December 31, 2006. SAB No. 108 permits existing public companies to initially apply its provisions either by (i) restating prior financial statements as if the “dual approach” had always been used or (ii), under certain circumstances, recording the cumulative effect of initially applying the “dual approach” as adjustments to the carrying values of assets and liabilities as of January 1, 2006 with an offsetting adjustment recorded to the opening balance of retained earnings. Duke Energy Indiana has historically used a dual approach for quantifying identified financial statement misstatements. Therefore, the adoption of SAB No. 108 did not have a material impact on Duke Energy Indiana’s consolidated results of operations, cash flows or financial position.

FASB Interpretation (FIN) 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109” (FIN 48). In July 2006, the FASB issued FIN 48, which provides guidance on accounting for income tax positions about which Duke Energy Indiana has concluded there is a level of uncertainty with respect to the recognition of a tax benefit in Duke Energy Indiana’s financial statements. FIN 48 prescribes the minimum recognition threshold a tax position is required to meet. Tax positions are defined very broadly and include not only tax deductions and credits but also decisions not to file in a particular jurisdiction, as well as the taxability of transactions. Duke Energy Indiana adopted FIN 48 effective January 1, 2007. See Note 13 for additional information.

FASB Staff Position (FSP) No. FIN 48-1, Definition of “Settlement” in FASB Interpretation No. 48 (FSP No. FIN 48-1). In May, 2007, the FASB staff issued FSP No. FIN 48-1 which clarifies the conditions under FIN 48 that should be met for a tax position to be considered effectively settled with the taxing authority. Duke Energy Indiana’s adoption of FIN 48 as of January 1, 2007 was consistent with the guidance in this FSP.

FSP No. AUG AIR-1, “Accounting for Planned Major Maintenance Activities,” (FSP No. AUG AIR-1). In September 2006, the FASB Staff issued FSP No. AUG AIR-1. This FSP prohibits the use of the accrue-in-advance method of accounting for planned major maintenance activities in annual and interim financial reporting periods, if no liability is required to be recorded for an asset retirement obligation based on a legal obligation for which the event obligating the entity has occurred. The FSP also requires disclosures regarding the method of accounting for planned major maintenance activities and the effects of implementing the FSP. The guidance in this FSP was effective for Duke Energy Indiana as of January 1, 2007. The adoption of FSP No. AUG AIR-1 did not have a material impact on Duke Energy Indiana’s consolidated results of operations, cash flows or financial position.

Emerging Issues Task Force (EITF) Issue No. 06-3, “How Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That Is, Gross versus Net Presentation) (EITF No. 06-3).” In June 2006, the EITF reached a consensus on EITF No. 06-3 to address any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer and may include, but are not limited to, sales, use, value added, and some excise taxes. For taxes within the Issue’s scope, the consensus requires that entities present such taxes on either a gross (i.e., included in revenues and costs) or net (i.e., exclude from revenues) basis according to their accounting policies, which should be disclosed. If such taxes are reported gross and are significant, entities should disclose the amounts of those taxes. Disclosures may be made on an aggregate basis. The consensus was effective for Duke Energy Indiana beginning January 1, 2007. The adoption of EITF No. 06-3 did not have a material impact on Duke Energy Indiana’s consolidated results of operations, cash flows or financial position.

The following new accounting standards have been issued but have not yet been adopted by Duke Energy Indiana as of September 30, 2007:

SFAS No. 157, “Fair Value Measurements” (SFAS No. 157). In September 2006, the FASB issued SFAS No. 157, which defines fair value, establishes a framework for measuring fair value in GAAP, and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements. However, in some cases, the application of SFAS No. 157 may change Duke Energy Indiana’s current practice for measuring and disclosing fair values under other accounting pronouncements that require or permit fair value measurements. For Duke Energy Indiana, SFAS No. 157 is effective as of January 1, 2008 and must be applied prospectively except in certain cases. Duke Energy Indiana is currently evaluating the impact of adopting SFAS No. 157, and cannot currently estimate the impact of SFAS No. 157 on its consolidated results of operations, cash flows or financial position.

SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (SFAS No. 159). In February 2007, the FASB issued SFAS No. 159, which permits entities to choose to measure many financial instruments and certain other items at fair value. For Duke Energy Indiana, SFAS No. 159 is effective as of January 1, 2008 and will have no impact on amounts presented for periods prior to the effective date. Duke Energy Indiana cannot currently estimate the impact of SFAS No. 159 on its consolidated results of operations, cash flows or financial position and has not yet determined whether or not it will choose to measure items subject to SFAS No. 159 at fair value.

13. Income Taxes and Other Taxes

Prior to the merger of Cinergy and Duke Energy on April 3, 2006, the taxable income of Duke Energy Indiana was reflected in Cinergy’s U.S. federal and state income tax returns. After the merger, the taxable income of Duke Energy Indiana is reflected in Duke Energy’s U.S. federal and state income tax returns. As a result of Duke Energy’s merger with Cinergy, Duke Energy Indiana entered into a tax sharing agreement with Duke Energy, where the separate return method is used to allocate tax expenses or benefits to the subsidiaries whose investments or results of operations provide these tax expenses or benefits. The accounting for income taxes essentially represents the income taxes that Duke Energy Indiana would incur if Duke Energy Indiana were a separate company filing its own tax return as a C-Corporation. The current tax sharing agreement Duke Energy Indiana has with Duke Energy is substantially the same as the tax sharing agreement between Duke Energy Indiana and Cinergy prior to the merger.

On January 1, 2007, Duke Energy Indiana adopted FIN 48. The following table shows the impacts of adoption of FIN 48 on Duke Energy Indiana’s Consolidated Balance Sheets.

	Increase/(Decrease)
	(in millions)
Liabilities
Other Liabilities (non-current)(a)	$	49
Interest Accrued (current)		(11	)
Deferred Income Taxes		(38	)
Total(b)	$	—

^(a) Includes liability for unrecognized tax benefits and accrued interest and penalties, net of gain contingencies that were not recorded prior to the adoption of FIN 48.

^(b) The adoption of FIN 48 resulted in the recognition of an immaterial after-tax cumulative effect to retained earnings, which reflects all adoption provisions of FIN 48, including those provisions related to unrecognized income tax benefits net of gain contingencies, and interest expense and penalties.

The following table shows the accounting for the adoption of FIN 48 on January 1, 2007 and the increase/(decrease) in Duke Energy Indiana’s unrecognized tax benefits from January 1, 2007 to September 30, 2007.

	January 1, 2007		Changes in Balances			September 30, 2007
	(in millions)

Interest Payable(b)	$	20	$	(9	)	$	11
Penalties Payable	$	—	$	—		$	—

^(a) Decrease in the liability of $17 million is primarily related to an $18 million settlement offer and a $4 million settlement, partially offset by a $5 million increase primarily related to the timing of certain deductions taken on tax returns in prior years.

^(b) Reflects all interest related to income taxes. The decrease in the liability was recorded as an increase to pre-tax income of $1 million and $9 million for the three and nine months ended September 30, 2007.

It is reasonably possible that Duke Energy Indiana will reflect an approximate $25 million reduction in unrecognized tax benefits in the next twelve months due to expected settlements.

Duke Energy Indiana has the following tax years open.

Jurisdiction	Tax Years
Federal	2000 and after
State	Closed through 2001, with the exception of any adjustments related to open federal years

Effective with the adoption of FIN 48, Duke Energy Indiana records, as it relates to taxes, interest expense as Interest Expense and interest income and penalties in Other Income and Expenses, net in the Consolidated Statements of Operations.

The $57 million increase in income tax expense for the year to date comparative periods September 30, 2007 and 2006 is primarily due to the $150 million increase in income before taxes. The $6 million increase in income tax expense for the quarter end comparative periods September 30, 2007 and 2006 is primarily due to the $14 million increase in income before taxes.

As of September 30, 2007 and December 31, 2006, approximately $22 million and $0 million, respectively, of deferred income taxes were included in Other within Current Assets in the Consolidated Balance Sheets. At September 30, 2007, this balance exceeded 5% of total current assets.

Excise Taxes. Certain excise taxes levied by state or local governments are collected by Duke Energy Indiana from its customers. These taxes, which are required to be paid regardless of Duke Energy Indiana’s ability to collect from the customer, are accounted for on a gross basis. When Duke Energy Indiana acts as an agent, and the tax is not required to be remitted if it is not collected from the customer, the taxes are accounted for on a net basis. Duke Energy Indiana’s excise taxes accounted for on a gross basis and recorded as operating revenues in the accompanying Consolidated Statements of Operations for the three and nine months ended September 30, 2007 and 2006 were as follows:

	Three Months Ended September 30				Nine Months Ended September 30

Net Income

The $93 million increase in Duke Energy Indiana’s Net income for the nine months ended September 30, 2007 as compared to 2006 was primarily due to the following factors:

Operating Revenues

The $69 million increase in Operating revenues was due primarily to:

• A $67 million increase in fuel and wholesale power revenues due primarily to power marketing contracts implemented in 2007 (see Operating Expenses below),

• A $47 million increase in retail revenues due primarily to favorable weather, in 2007 as compared to 2006,

• A $22 million increase in retail revenues related to recovery of environmental compliance construction costs, and

• A $4 million increase due to completion of temporary rate reductions associated with regulatory approval of the Cinergy Corp. (Cinergy) merger with Duke Energy Corporation (Duke Energy).

Partially offset by:

• A $56 million decrease in emission allowance tracker retail revenues driven by new rates implemented in January 2007 which included credits for the gain on sales of native load allowances made in the summer of 2006 (see Operating Expenses below), and

• An approximate $10 million decrease in revenues due to regional transmission operator (RTO) netting that began in April 2006 pursuant to a Federal Energy Regulatory Commission (FERC) order (see Operating Expenses below).

23

PART I

Operating Expenses

The $69 million decrease in Operating expenses was due primarily to:

• A $48 million decrease in emission allowance expenses driven by recognition of the gain on sales of native load allowances previously deferred in the summer of 2006 (see Operating Revenues above),

• A $26 million decrease in emission allowance expenses due to higher non-native tonnage emissions and higher per unit price for non-native allowances in 2006,

• A $15 million decrease in non-retail fuel expense driven by a 2006 adverse ruling from the Indiana Utility Regulatory Commission related to fuel, and

• An approximate $10 million decrease in expenses due to RTO netting that began in April 2006 (see Operating Revenues above).

Partially offset by:

• A $22 million increase in fuel costs due to power marketing contracts implemented in 2007 (see Operating Revenues above).

Operating Income

• The increase in Operating income resulted primarily from favorable weather, wholesale power marketing contracts implemented in 2007 and decreased emission allowance expenses.

Other Income and Expenses, net

The increase in Other income and expenses, net was due primarily to:

• A $2 million increase in the equity component of allowance for funds used during construction resulting from an increase in the equity rate, offset by construction projects relating to assets placed in service.

Interest Expense

The decrease in Interest expense was due primarily to:

• A $6 million decrease related to financings through Duke Energy money pool agreement.

Income Tax Expense

• The $57 million increase in Income tax expense was due primarily to a $150 million increase in pre-tax income.
