CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION
This document includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are based on management’s beliefs and assumptions. These forward-looking statements are identified by terms and phrases such as “anticipate,” “believe,” “intend,” “estimate,” “expect,” “continue,” “should,” “could,” “may,” “plan,” “project,” “predict,” “will,” “potential,” “forecast,” “target,” “guidance,” “outlook,” and similar expressions. Forward-looking statements involve risks and uncertainties that may cause actual results to be materially different from the results predicted. Factors that could cause actual results to differ materially from those indicated in any forward-looking statement include, but are not limited to:
State, federal and foreign legislative and regulatory initiatives, including costs of compliance with existing and future environmental requirements or climate change, as well as rulings that affect cost and investment recovery or have an impact on rate structures or market prices;
The extent and timing of the costs and liabilities relating to the Dan River ash basin release and compliance with current regulations and any future regulatory changes related to the management of coal ash;
The ability to recover eligible costs, including those associated with future significant weather events, and earn an adequate return on investment through the regulatory process;
The costs of decommissioning Crystal River Unit 3 could prove to be more extensive than amounts estimated and all costs may not be fully recoverable through the regulatory process;
Credit ratings of the Duke Energy Registrants may be different from what is expected;
Costs and effects of legal and administrative proceedings, settlements, investigations and claims;
Industrial, commercial and residential growth or decline in service territories or customer bases resulting from customer usage patterns, including energy efficiency efforts and use of alternative energy sources, including self-generation and distributed generation technologies;
Additional competition in electric markets and continued industry consolidation;
Political and regulatory uncertainty in other countries in which Duke Energy conducts business;
The influence of weather and other natural phenomena on operations, including the economic, operational and other effects of severe storms, hurricanes, droughts and tornadoes;
The ability to successfully operate electric generating facilities and deliver electricity to customers;
The impact on facilities and business from a terrorist attack, cybersecurity threats, data security breaches and other catastrophic events;
The inherent risks associated with the operation and potential construction of nuclear facilities, including environmental, health, safety, regulatory and financial risks;
The timing and extent of changes in commodity prices, interest rates and foreign currency exchange rates and the ability to recover such costs through the regulatory process, where appropriate, and their impact on liquidity positions and the value of underlying assets;
The results of financing efforts, including the ability to obtain financing on favorable terms, which can be affected by various factors, including credit ratings and general economic conditions;
Declines in the market prices of equity and fixed income securities and resultant cash funding requirements for defined benefit pension plans, other post-retirement benefit plans and nuclear decommissioning trust funds;
Construction and development risks associated with the completion of Duke Energy Registrants’ capital investment projects in existing and new generation facilities, including risks related to financing, obtaining and complying with terms of permits, meeting construction budgets and schedules, and satisfying operating and environmental performance standards, as well as the ability to recover costs from customers in a timely manner or at all;
Changes in rules for regional transmission organizations, including changes in rate designs and new and evolving capacity markets, and risks related to obligations created by the default of other participants;
The ability to control operation and maintenance costs;
The level of creditworthiness of counterparties to transactions;
Employee workforce factors, including the potential inability to attract and retain key personnel;
The ability of subsidiaries to pay dividends or distributions to Duke Energy Corporation holding company (the Parent);
The performance of projects undertaken by our nonregulated businesses and the success of efforts to invest in and develop new opportunities;
The effect of accounting pronouncements issued periodically by accounting standard-setting bodies;
The impact of potential goodwill impairments;
The ability to reinvest prospective undistributed earnings of foreign subsidiaries or repatriate such earnings on a tax-efficient basis; and
The ability to successfully complete future merger, acquisition or divestiture plans.




In light of these risks, uncertainties and assumptions, the events described in the forward-looking statements might not occur or might occur to a different extent or at a different time than described. Forward-looking statements speak only as of the date they are made; the Duke Energy Registrants undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise that occur after that date.

BASIS OF PRESENTATION
Duke Energy completed the sale of Duke Energy Ohio's nonregulated Midwest generation business and Duke Energy Retail Sales LLC (Duke Energy Retail), a retail sales business owned by Duke Energy, to Dynegy on April 2, 2015. The results of operations of these businesses prior to the date of sale have been classified as Discontinued Operations on the Condensed Consolidated Statements of Operations for all periods presented. Duke Energy has elected to present cash flows of discontinued operations combined with cash flows of continuing operations. Unless otherwise noted, the notes to these Condensed Consolidated Financial Statements exclude amounts related to discontinued operations, for all periods presented, assets held for sale and liabilities associated with assets held for sale as of March 31, 2015.sale. See Note 2 (Midwest Generation Exit) for additional information.
These Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles (GAAP) in the U.S. for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these Condensed Consolidated Financial Statements do not include all information and notes required by GAAP in the U.S. for annual financial statements. Since the interim Condensed Consolidated Financial Statements and Notes do not include all information and notes required by GAAP in the U.S. for annual financial statements, the Condensed Consolidated Financial Statements and other information included in this quarterly report should be read in conjunction with the Consolidated Financial Statements and Notes in the Duke Energy Registrants’ combined Annual Report on Form 10-K for the year ended December 31, 2014.
The information in these combined notes relate to each of the Duke Energy Registrants as noted in the Index to the Combined Notes to Condensed Consolidated Financial Statements. However, none of the registrants makes any representations as to information related solely to Duke Energy or the subsidiaries of Duke Energy other than itself.

These Condensed Consolidated Financial Statements reflect all normal recurring adjustments in the opinion of the respective companies’ management, necessary to fairly present the financial position and results of operations of each of the Duke Energy Registrants. Amounts reported in Duke Energy’s interim Condensed Consolidated Statements of Operations and each of the Subsidiary Registrants’ interim Condensed Consolidated Statements of Operations and Comprehensive Income are not necessarily indicative of amounts expected for the respective annual periods due to effects of seasonal temperature variations on energy consumption, regulatory rulings, timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices and other factors.
In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
Certain prior year amounts have been reclassified to conform to the current year presentation.
UNBILLED REVENUE
Revenues on sales of electricity and natural gas are recognized when service is provided or the product is delivered. Unbilled revenues are recognized by applying customer billing rates to the estimated volumes of energy delivered but not yet billed. Unbilled revenues can vary significantly from period to period as a result of seasonality, weather, customer usage patterns, customer mix, average price in effect for customer classes and meter reading schedules.
Unbilled revenues are included within Receivables and Restricted receivables of variable interest entities on the Condensed Consolidated Balance Sheets as shown in the following table.

NEW ACCOUNTING STANDARDS
The new accounting standards adopted for 2015 and 2014 had no significant impact on the presentation or results of operations, cash flows or financial position of the Duke Energy Registrants.
ASC 205 Reporting Discontinued Operations. In April 2014, the Financial Accounting Standards Board (FASB) issued revised accounting guidance for reporting discontinued operations. A discontinued operation would be either (i) a component of an entity or a group of components of an entity that represents a separate major line of business or major geographical area of operations that either has been disposed of or is part of a single coordinated plan to be classified as held for sale or (ii) a business that, on acquisition, meets the criteria to be classified as held for sale.
For the Duke Energy Registrants, this revised accounting guidance is effective on a prospective basis for interim and annual periods beginningqualified disposals of components or classifications as held for sale that occur after January 1, 2015. Under the standard, the guidance is not effective for a component classified as held for sale before the effective date even if the disposal occurs after the effective date of the guidance. Duke Energy has not reported any discontinued operations under the revised accounting guidance.
The following new Accounting Standards Updates (ASUs) have been issued, but have not yet been adopted by the Duke Energy Registrants, as of March 31,June 30, 2015.
ASC 606 Revenue from Contracts with Customers. In May 2014, the FASB issued revised accounting guidance for revenue recognition from contracts with customers. The core principle of this revised accounting guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments in this update also require disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.
For the Duke Energy Registrants, this revised accounting guidance is effective for interim and annual periods beginning January 1, 2017. However,The FASB has approved the FASB is considering allowingissuance of a new ASU to allow companies toa one year delay implementation for one year.of implementation. Duke Energy is currently evaluating requirements, and the ultimate impact of the revised accounting guidance has not yet been determined.
ASC 835 Presentation of Debt Issuance Costs. In April 2015, the FASB issued revised accounting guidance for the presentation of debt issuance costs. The core principle of this revised accounting guidance is that debt issuance costs are not assets, but adjustments to the carrying cost of debt.
This revised accounting guidance would be effective retroactively beginning January 1, 2016 for Duke Energy, but can be adopted earlier. Based on the amount of debt issuance costs reported as of December 31, 2014 in the Consolidated Balance Sheets, Duke Energy would record a

This revised accounting guidance would be effective retroactively for Duke Energy beginning January 1, 2016, but can be adopted earlier. Based on the amount of debt issuance costs reported in the Consolidated Balance Sheets as of December 31, 2014, Duke Energy would record a reduction of $137approximately $118 million in Regulatory Assets and Deferred Debits and Long-Term Debt. Duke Energy is currently evaluating whether implementation will occur prior to the first quarter of 2016.
2. ACQUISITIONS AND DISPOSITIONS

Duke Energy Carolinas
William States Lee Combined Cycle Facility
On April 9, 2014, the PSCSC granted Duke Energy Carolinas and North Carolina Electric Membership Corporation (NCEMC) a Certificate of Environmental Compatibility and Public Convenience and Necessity (CECPCN) for the construction and operation of a 750 MW combined cyclecombined-cycle natural gas-fired generating plant at Duke Energy Carolinas' existing William States Lee Generating Station in Anderson, South Carolina. On May 16, 2014, Duke Energy Carolinas announced its intention to beginbegan construction in summerJuly 2015, and estimates a cost to build of $600 million for its share of the facility, including allowance for funds used during construction (AFUDC). The project is expected to be commercially available in late 2017. NCEMC will own approximately 13 percent of the project. On July 3, 2014, the South Carolina Coastal Conservation League (SCCCL) and Southern Alliance for Clean Energy (SACE) jointly filed a Notice of Appeal with the Court of Appeals of South Carolina seeking the court's review of the PSCSC's decision. The case has been fully briefed and is pending in the Court of Appeals. Duke Energy Carolinas cannot predict the outcome of this matter.
Duke Energy Progress
Sutton Black Start Combustion Turbine CPCN
On April 15, 2015, Duke Energy Progress filed a CPCNcertificate of public convenience and necessity (CPCN) application with the NCUC for approval to construct an 84 MW black start combustion turbine (CT) project at the existing Sutton plantPlant (Sutton Black Start CT Project). The Sutton Black Start CT Project would replace three existing CTs with total capacity of 61 MW with two new 42 MW CT units with black start and fast start capability. In addition to peaking system capacity, the Sutton Black Start CT Project will provide regional black start capability and tertiary backup power services for the Brunswick Nuclear Plant. In June 2015, the Public Staff of the NCUC recommended the NCUC approve Duke Energy Progress' application. On August 3, 2015, the NCUC issued an order granting the application and requiring annual construction and cost progress reports.
Western Carolinas Modernization Plan
In May 2015, Duke Energy Progress announced a $1.1 billion plan to modernize the Western Carolinas energy system. The NCUC has scheduledplan includes retiring the Asheville coal-fired plant, building a 650 MW combined-cycle natural gas power plant and installing solar generation at the site, building new transmission lines and upgrading area substations. These investments will be made within the next five years in North Carolina and South Carolina. Duke Energy is also working with the local natural gas distribution company to upgrade an evidentiary hearingexisting natural gas pipeline to serve the natural gas plant. On June 24, 2015, the North Carolina governor signed into law the Mountain Energy Act of 2015 (Mountain Energy Act) which provides for an expedited CPCN process for the proposed Asheville combined-cycle project and extends certain North Carolina Coal Ash Management Act of 2014 (Coal Ash Act) deadlines for the coal ash basin at the Asheville Plant site. The plan requires various approvals including regulatory approvals in North Carolina and South Carolina.
The carrying value of the 376 MW Asheville coal-fired plant, including associated ash basin closure costs, of $460 million is included in Generation facilities to be retired, net on Duke Energy Progress' Condensed Consolidated Balance Sheet as of June 22, 2015 and a decision is expected by October30, 2015.
Duke Energy Florida
FERC Transmission Return on Equity Complaint
Seminole Electric Cooperative, Inc. and Florida Municipal Power Agency filed multiple complaints with the FERC alleging Duke Energy Florida's current rate of return on equity in transmission formula rates of 10.8 percent is unjust and unreasonable. The latest complaint, filed on August 12, 2014, claims the rate of return on equity should be reduced to 8.69 percent. The FERC consolidated all complaints for the purposes of settlement, hearing and decision. TheOn July 21, 2015, the parties are engagedfiled with the FERC for approval of a settlement agreement under which (i) Duke Energy Florida will pay a total of $14.1 million as refunds for all periods through December 31, 2014, (ii) the rate of return on equity will be 10 percent effective January 1, 2015, and (iii) none of the parties will seek a change in settlement discussions.

Purchase of Osprey Energy Center
In December 2014, Duke Energy Florida and Osprey Energy Center, LLC, a wholly owned subsidiary of Calpine Corporation (Calpine), entered into an Asset Purchase and Sale Agreement for the purchase of a 599 MW combined cyclecombined-cycle natural gas plant in Auburndale, Florida (Osprey Plant acquisition) for approximately $166 million. ClosingOn January 30, 2015, Duke Energy Florida petitioned the FPSC requesting a determination that the Osprey Plant acquisition or, alternatively, the construction of a 320 MW combustion turbine at its existing Suwannee generating facility (Suwannee project) with an estimated cost of $197 million, is subjectthe most cost-effective generation alternative to meet Duke Energy Florida's remaining generation need prior to 2018. On July 21, 2015, the approvalFPSC approved the Osprey Plant acquisition as the most cost-effective alternative and an order is expected in August 2015. On July 24, 2015, the FERC issued an order approving the Osprey Plant acquisition. Closing of the FERC, FPSC andacquisition is contingent upon the expiration of the Hart Scott Rodino waiting period and is expected to occur by the first quarter of 2017 upon the expiration of an existing Power Purchase Agreement between Calpine and Duke Energy Florida.
Crystal River Unit 3
On January 30,May 22, 2015, Duke Energy Florida petitioned the FPSC requestingfor approval to include in base rates the revenue requirement for the Crystal River Unit 3 Regulatory asset as authorized by the 2013 Revised and Restated Stipulation and Settlement Agreement (2013 Agreement). The value of the Crystal River Unit 3 Regulatory asset to be recovered is projected to be $1.298 billion at December 31, 2015. Based upon this projected value, the initial annual revenue requirement is estimated to be $170 million. 
In June 2015, the Governor of Florida signed into law legislation to allow utilities to petition for a determination that the Osprey Plant acquisition or, alternatively, the constructionfinancing order for securitization of a 320 MW combustion turbine at its existing Suwannee generating facility with an estimated cost of $197 million is the most cost-effectivecertain retired nuclear generation alternative to meet Duke Energy Florida's remaining generation need prior to 2018. A hearing with the FPSC is scheduled for June 2015.assets. On March 13,July 27, 2015, Duke Energy Florida madepetitioned the FPSC for a filing requesting FERC approvalfinancing order to finance the Crystal River Unit 3 Regulatory asset with low-cost securities. If the FPSC issues an acceptable financing order and Duke Energy Florida issues the bonds, securitization would replace the base rate recovery methodology established in the 2013 Agreement described above, and would result in a lower rate impact to customers. The annual revenue requirement with securitization, subject to changes in assumed interest rates and timing of issuance of the Osprey Plant acquisition by July 30, 2015. In the FERC proceeding, no protests were filed. Seminole Electric Cooperative intervened to request clarification concerning the transmission facilitiessecuritization bonds, is estimated to be constructedapproximately $100 million. The FPSC is expected to hold a hearing on both the Crystal River Unit 3 Regulatory asset filing and the securitization filing in connectionOctober 2015. Duke Energy Florida cannot predict the outcome of this matter.
Levy Nuclear Project
On April 16, 2015, the FPSC approved Duke Energy Florida’s petition to cease collection of the Levy Nuclear Project fixed charge beginning with the Osprey Plant acquisition. If timelyfirst billing cycle in May. Duke Energy Florida also sought approval to defer collection of the Osprey Plant acquisition is$54 million regulatory asset until litigation with Westinghouse Electric Co. concludes. The FPSC found that it was unnecessary to act on the request, finding that its previous order requiring the downward adjustment in projected costs primarily affected the timing of when the fixed charge would end, but that it did not received from the FERC, the Suwannee project woulddisallow recovery of any costs previously determined to be constructed.prudent.
Duke Energy Ohio
2014 Electric Security Plan
In April 2015, the PUCO modified and approved Duke Energy Ohio's proposed ESP, with a three-year term and an effective date of June 1, 2015. The PUCO approved a competitive procurement process for SSO load, a distribution capital investment rider, and a tracking mechanism for incremental distribution expenses caused by major storms. The PUCO order also approved a placeholder tariff for a price stabilization rider, but denied Duke Energy Ohio's specific request to include OVEC in the rider at this time; however, the order allows Duke Energy Ohio to submit additional information to request recovery in the future. On May 4, 2015, Duke Energy Ohio filed an application for rehearing requesting the PUCO to modify or amend certain aspects of the order. On May 14, 2015, Duke Energy Ohio completed a competitive bidding process to procure a portion of the supply for its SSO load for the term of the ESP. The PUCO approved the results on May 15, 2015. On May 28, 2015, the PUCO granted all applications for rehearing filed in the case for future consideration. Duke Energy Ohio cannot predict the outcome of this matter.
2012 Natural Gas Rate Case
On November 13, 2013, the PUCO issued an order approving a settlement among Duke Energy Ohio, the PUCO Staff and intervening parties (the Gas Settlement). The Gas Settlement provided for (i) no increase in base rates for natural gas distribution service and (ii) a return on equity of 9.84 percent. The Gas Settlement provided for a subsequent hearing on Duke Energy Ohio’s request for rider recovery of environmental remediation costs associated with its former manufactured gas plant (MGP) sites. After the conclusion of the evidentiary hearing and briefs, theThe PUCO authorized Duke Energy Ohio to recover $56 million, excluding carrying costs, of environmental remediation costs. The MGP rider became effective in April 2014 for a five-year period. On March 31, 2014, Duke Energy Ohio filed an application with the PUCO to adjust the MGP rider for investigation and remediation costs incurred in 2013.
Certain consumer groups appealed the PUCO’s decision authorizing the MGP rider to the Ohio Supreme Court and further asked the court to stay implementation of the PUCO’s order and collections under the MGP rider pending their appeal. The Ohio Supreme Court granted the motion to stay and subsequently required the posting of a bond to effectuate the stay. When the bond was not posted, the PUCO approved Duke Energy Ohio’s request, in January 2015, to reinstate collections under the MGP rider and Duke Energy Ohio resumed billings. Amounts collected prior to the suspension of the rider were immaterial. On March 31, 2015, Duke Energy Ohio filed an application to adjust the MGP rider to recover remediation costs incurred in 2014. Duke Energy Ohio cannot predict the outcome of the appeal of this matter.
Regional Transmission Organization (RTO) Realignment

On December 22, 2010, the KPSC approved Duke Energy Kentucky’s request to effect the RTO realignment, subject to a commitment not to seek double recovery in a future rate case of the transmission expansion fees that may be charged by MISO and PJM in the same period or overlapping periods.
On May 25, 2011, the PUCO approved a settlement between Duke Energy Ohio, Ohio Energy Group, the Office of Ohio Consumers’ Counsel and the PUCO Staff related to Duke Energy Ohio’s recovery of certain costs of the RTO realignment via a non-bypassable rider. Duke Energy Ohio is allowed to recover all MISO Transmission Expansion Planning (MTEP) costs, including but not limited to Multi-ValueMulti Value Project (MVP) costs, directly or indirectly charged to Ohio customers. Duke Energy Ohio also agreed to vigorously defend against any charges for MVP projects from MISO.
Upon its exit from MISO on December 31, 2011, Duke Energy Ohio recorded a liability for its exit obligation and share of MTEP costs, excluding MVP. This liability was recorded within Other in Current liabilities and Other in Deferred credits and other liabilities on Duke Energy Ohio’s Condensed Consolidated Balance Sheets.
The following table provides a reconciliationAs of the beginning and ending balances ofJune 30, 2015, Duke Energy Ohio’sOhio had recorded obligations of $93 million related to its withdrawal from MISO. As of March 31, 2015, $73 million is recorded asMISO and a Regulatory asset of $73 million recorded on Duke Energy Ohio'sthe Condensed Consolidated Balance Sheets.
MTEP costs billed by MISO are recovered by Duke Energy Ohio through a non-bypassable rider.

MVP. MISO approved 17 MVP proposals prior to Duke Energy Ohio’s exit from MISO on December 31, 2011. Construction of these projects is expected to continue through 2020. Costs of these projects, including operating and maintenance costs, property and income taxes, depreciation and an allowed return, are allocated and billed to MISO transmission owners.
On December 29, 2011, MISO filed a tariff with the FERC providing for the allocation of MVP costs to a withdrawing owner based on monthly energy usage. The FERC set for hearing (i) whether MISO’s proposed cost allocation methodology to transmission owners who withdrew from MISO prior to January 1, 2012 is consistent with the tariff at the time of their withdrawal from MISO, and, (ii) if not, what the amount of and methodology for calculating any MVP cost responsibility should be. On July 16, 2013, a FERC Administrative Law Judge (ALJ) issued an initial decision. Under this initial decision, Duke Energy Ohio would be liable for MVP costs. Duke Energy Ohio filed exceptions to the initial decision, requesting the FERC overturn the ALJ’s decision. After reviewing the initial decision, along with all exceptions and responses filed by the parties, the FERC will issue a final decision. Duke Energy Ohio fully intends to appeal to the federal court of appeals if the FERC affirms the ALJ’s decision. Duke Energy Ohio cannot predict the outcome of these proceedings.
In 2012, MISO estimated Duke Energy Ohio’s MVP obligation over the period from 2012 to 2071 at $2.7 billion, on an undiscounted basis. The estimated obligation is subject to great uncertainty including the ultimate cost of the projects, the annual costs of operations and maintenance, taxes and return over the project lives, the number of years in service for the projects and the allocation to Duke Energy Ohio.
Any liability related to the MISO MVP matter or MTEP costs attributable to the Disposal Group was not transferred to Dynegy upon the sale of the nonregulated Midwest generation business.
FERC Transmission Return on Equity and MTEP Cost Settlement
On October 14, 2011, Duke Energy Ohio and Duke Energy Kentucky submitted with the FERC proposed modifications to the PJM Interconnection Open Access Transmission Tariff pertaining to recovery of the transmission revenue requirement as PJM transmission owners. The filing was made in connection with Duke Energy Ohio's and Duke Energy Kentucky's move from MISO to PJM effective January 1, 2012. On April 24, 2012, the FERC issued an order accepting the proposed filing effective January 1, 2012, except that the order denied a request to recover certain costs associated with the move from MISO to PJM without prejudice to the right to submit another filing seeking such recovery and including certain additional evidence, and set the rate of return on equity of 12.38 percent for settlement and hearing. On April 16, 2015, the FERC approved a settlement agreement between Duke Energy Ohio, Duke Energy Kentucky and six PJM transmission customers with load in the Duke Energy Ohio and Duke Energy Kentucky zone. The principal terms of the settlement agreement are that, effective upon the date of FERC approval, (i) the return on equity for wholesale transmission service is reduced to 11.38 percent, (ii) the settling parties agreed not to seek a change in the return on equity that would be effective prior to June 1, 2017, and (iii) Duke Energy Ohio and Duke Energy Kentucky will recover 30 percent of the wholesale portion of costs arising from their obligation to pay any portion of the costs of projects included in any MTEP that was approved prior to the date of Duke Energy Ohio's and Duke Energy Kentucky's integration into PJM.
Duke Energy Indiana
Edwardsport Integrated Gasification Combined Cycle (IGCC) Plant
On November 20, 2007, the IURC granted Duke Energy Indiana a CPCN for the construction of the Edwardsport IGCC power plant.Plant. The Citizens Action Coalition of Indiana, Inc., Sierra Club, Inc., Save the Valley, Inc., and Valley Watch, Inc. (collectively, the Joint Intervenors) were intervenors in several matters related to the Edwardsport IGCC Plant.

The ninth semi-annual IGCC rider is currently pending. The twelfth and thirteenth semi-annual IGCC riders were combined for hearings which were held in February 2015. Issues in this proceeding include whether the IGCC plantorder was properly declared in service for ratemaking purposes in June 2013 and the operational performance of the plant during its initial ten months of operations.
The ninth and tenth semi-annual IGCC rider orders have been appealed by the Joint Intervenors. On August 21, 2014, the Indiana Court of Appeals affirmed the IURC order in the tenth IGCC rider proceeding and on October 29, 2014 denied Joint Intervenors' request for rehearing. The Joint Intervenors requested the Indiana Supreme Court to review the decision, which was denied on April 23, 2015, concluding the appeal. On September 8, 2014, the Indiana Court of Appeals remanded the IURC order in the ninth IGCC rider proceeding back to the IURC for further findings. On February 25, 2015, the IURC issued a new order upholding its prior decision and providingprovided additional detailed findings. Joint Intervenors have appealed this remand order to the Indiana Court of Appeals.
The 10th semi-annual IGCC rider order was also appealed by the Joint Intervenors. On August 21, 2014 the Indiana Court of Appeals affirmed the IURC order in the 10th IGCC rider proceeding and on October 29, 2014 denied the Joint Intervenors' request for rehearing.

An order on the 11th semi-annual IGCC rider is currently pending. The 12th and 13th semi-annual IGCC riders were combined for hearings which were held in February 2015 and an order is currently pending. Issues in this proceeding include whether the IGCC plant was properly declared in service for ratemaking purposes in June 2013 and the operational performance of the plant during its initial 10 months of operations. Duke Energy Indiana has filed the 14th and 15th semi-annual IGCC rider proceedings, with a hearing scheduled in November 2015.
On April 2, 2014, the IURC established a subdocket to Duke Energy Indiana’s current fuel adjustment clause proceeding. In this fuel adjustment subdocket, the IURC intends to review underlying causes for net negative generation amounts at the Edwardsport IGCC plantPlant during the period September through November 2013. Duke Energy Indiana contends the net negative generation is related to the consumption of fuel and auxiliary power when the plant was in start-up or off line. In addition to the OUCC, the Duke Energy Indiana Industrial Group, Nucor Steel-Indiana, Steel Dynamics, Inc., and the Joint Intervenors are parties to the subdocket. The IURC has deferred the fuel adjustment subdocket until resolution of the twelfth12th and thirteenth13th semi-annual IGCC rider proceedings. In addition, although the IURC approved fuel adjustment clause recovery for the period December 2013 through March 2014, it determined such fuel costs reasonably related to the operational performance of the Edwardsport IGCC plantPlant shall be subject to refund pending the outcome of the twelfth12th and thirteenth13th semi-annual IGCC riders.
On August 6, 2015, the IURC granted a motion to defer ruling on all pending matters until September 15, 2015 to allow time for settlement discussions. The Commission is expected to proceed with issuance of an order if the parties do not reach a settlement agreement. Duke Energy Indiana cannot predict the outcome of the fuel adjustment clause proceedings or pending and future IGCC rider proceedings.

FERC Transmission Return on Equity Complaint
Customer groups have filed with the FERC complaints against MISO and its transmission-owning members, including Duke Energy Indiana, alleging, among other things, that the current base rate of return on equity earned by MISO transmission owners of 12.38 percent is unjust and unreasonable. The latest complaint, filed on February 12, 2015, claims the base rate of return on equity should be reduced to 8.67 percent and requests a consolidation of complaints. On January 5, 2015, the FERC issued an order accepting the MISO transmission owners 0.50 percent adder to the base rate of return on equity based on participation in an RTO subject to it being applied to a return on equity that is shown to be just and reasonable in the pending return on equity complaint. Settlement procedures in the base return on equity proceeding were terminated and a hearing is scheduled for August 17, 2015. Duke Energy Indiana cannot predict the outcome of this matter.
Grid Infrastructure Improvement Plan
On August 29, 2014, Duke Energy Indiana filed a seven-year grid infrastructure improvement plan with the IURC with an estimated cost of $1.9 billion, focusing on the reliability, integrity and modernization of the transmission and distribution system. If approved, 80 percentIn May 2015, the IURC denied the proposal due to an insufficient level of detailed projects and cost estimates in the costs will be recovered through a rate tracker. The remaining 20 percent are subject to deferral and subsequent recovery through future rate case proceedings. Hearings were held in January 2015 andplan. Duke Energy Indiana expectsis evaluating the order and plans to file a decision in mid-2015.revised infrastructure improvement plan by the end of 2015.
OTHER REGULATORY MATTERS
Atlantic Coast Pipeline
On September 2, 2014, Duke Energy, Dominion Resources (Dominion), Piedmont Natural Gas and AGL Resources announced the formation of a company, Atlantic Coast Pipeline, LLC (ACP), to build and own the proposed Atlantic Coast Pipeline (the pipeline), a 550-mile interstate natural gas pipeline. The pipeline is designed to meet the needs identified in requests for proposals by Duke Energy Carolinas, Duke Energy Progress and Piedmont Natural Gas. Dominion will build and operate the pipeline and will own 45 percent. Duke Energy will have a 40 percent ownership interest in ACP through its Commercial PowerPortfolio segment. The remaining share will be owned by Piedmont Natural Gas and AGL Resources. Duke Energy Carolinas and Duke Energy Progress, among others, will be customers of the pipeline. Purchases will be made under several 20-year supply contracts, subject to state regulatory approval. In October 2014, the NCUC and PSCSC approved the Duke Energy Carolinas and Duke Energy Progress requests to enter into certain affiliate agreements, pay compensation to ACP and to grant a waiver of certain Code of Conduct provisions relating to contractual and jurisdictional matters. The project will require FERC approval, which ACP will seek to secure by summer 2016. The estimated in-service date of the pipeline is late 2018.
Sabal Trail Transmission, LLC Pipeline
On May 4, 2015, Duke Energy acquired a 7.5 percent ownership interest from Spectra Energy in the proposed 500-mile Sabal Trail natural gas pipeline. Spectra Energy will continue to own 59.5 percent of the pipeline and NextEra Energy will own the remaining 33 percent of the pipeline. The pipeline will traverse Alabama, Georgia and Florida to meet rapidly growing demand for natural gas in those states. The primary customers of the pipeline, Duke Energy Florida and Florida Power & Light Company, have each contracted to buy pipeline capacity for 25-year initial terms. The pipeline, scheduled to begin service in 2017, requires federal and other regulatory approvals. 
East Bend Station
On December 30, 2014, Duke Energy Ohio acquired The Dayton Power and Light Company's (DP&L) 31 percent interest in East Bend Station for approximately $12.4 million. The purchase price, in accordance with FERC guidelines, was reflected with the net purchase amount as an increase to property, plant and equipment as of December 31, 2014 and with the DP&L's historical original cost as an increase to property, plant and equipment and accumulated depreciation as of June 30, 2015.

NC WARN FERC Complaint
On December 16, 2014, NC WARNNorth Carolina Waste Awareness and Reduction Network filed a complaint with the FERC against Duke Energy Carolinas and Duke Energy Progress that alleged (i) Duke Energy Carolinas and Duke Energy Progress manipulated the electricity market by constructing costly and unneeded generation facilities leading to unjust and unreasonable rates; (ii) Duke Energy Carolinas and Duke Energy Progress failed to comply with Order 1000 by not effectively connecting their transmission systems with neighboring utilities which also have excess capacity; (iii) the plans of Duke Energy Carolinas and Duke Energy Progress for unrealistic future growth lead to unnecessary and expensive generating plants; (iv) the FERC should investigate the practices of Duke Energy Carolinas and Duke Energy Progress and the potential benefits of having them enter into a regional transmission organization; and (v) the FERC should force Duke Energy Carolinas and Duke Energy Progress to purchase power from other utilities rather than construct wasteful and redundant power plants. ANC WARN also filed a copy of the complaint was filed with the PSCSC on January 6, 2015. Duke Energy Carolinas and Duke Energy Progress have filed responses requesting dismissal of the complaint with the FERC and the PSCSC. In April 2015, the FERC and the PSCSC issued separate orders dismissing the NC WARN petition. On May 14, 2015, NC WARN filed with FERC a motion for reconsideration.
Planned and Potential Coal Plant Retirements
The Subsidiary Registrants periodically file Integrated Resource Plans (IRP) with their state regulatory commissions. The IRPs provide a view of forecasted energy needs over a long term (10 to 20 years), and options being considered to meet those needs. Recent IRPs filed by the Subsidiary Registrants included planning assumptions to potentially retire certain coal-fired generating facilities in North Carolina, Florida Ohio and Indiana earlier than their current estimated useful lives. These facilities do not have the requisite emission control equipment, primarily to meet United States Environmental Protection Agency (EPA) regulations recently approved or proposed.

Remediation Activities
The Duke Energy Registrants are responsible for environmental remediation at various contaminated sites. These include some properties that are part of ongoing operations and sites formerly owned or used by Duke Energy entities. These sites are in various stages of investigation, remediation and monitoring. Managed in conjunction with relevant federal, state and local agencies, activities vary with site conditions and locations, remediation requirements, complexity and sharing of responsibility. If remediation activities involve joint and several liability provisions, strict liability, or cost recovery or contribution actions, the Duke Energy Registrants could potentially be held responsible for contamination caused by other potentially responsible parties, and may also benefit from insurance policies or contractual indemnities that cover some or all cleanup costs. Liabilities are recorded when losses become probable and are reasonably estimable. The total costs that may be incurred cannot be estimated because the extent of environmental impact, allocation among potentially responsible parties, remediation alternatives and/or regulatory decisions have not yet been determined. Additional costs associated with remediation activities are likely to be incurred in the future and could be significant. Costs are typically expensed as Operation, maintenance and other in the Condensed Consolidated Statements of Operations unless regulatory recovery of the costs is deemed probable.
The following tables contain information regarding reserves for probable and estimable costs related to the various environmental sites. These reserves are recorded in Other within Deferred Credits and Other Liabilities on the Condensed Consolidated Balance Sheets.

North Carolina and South Carolina Ash Basins
On February 2, 2014, a break in a stormwater pipe beneath an ash basin at Duke Energy Carolinas’ retired Dan River steam stationSteam Station caused a release of ash basin water and ash into the Dan River. On February 8, 2014, a permanent plug was installed in the stormwater pipe, stopping the release of materials into the river. Duke Energy Carolinas estimates 30,000 to 39,000 tons of ash and 24 million to 27 million gallons of basin water were released into the river. In July 2014, Duke Energy completed remediation work identified by the EPA and continues to cooperate with the EPA's civil enforcement process. Total repairs and remediation expenses incurred by Duke Energy Carolinas related to the release were approximately $24 million. No additional expenses were recorded in the first quarter of 2015. Duke Energy Carolinas will not seek recovery of these costs from ratepayers. See the "Litigation" section below for additional information on litigation, investigations and enforcement actions related to ash basins, including the Memorandum of Plea Agreement (Plea Agreements) in connection to the North Carolina Ash Basin Grand Jury Investigation. Other costs related to the Dan River release, including pending or future state or federal civil enforcement proceedings, future regulatory directives, natural resources damages, additional pending litigation, future claims or litigation, and long-term environmental impact costs cannot be reasonably estimated at this time.

On September 20, 2014, the North Carolina Coal Ash Management Act of 2014 (Coal Ash Act) became law.law and was amended on June 24, 2015, by the Mountain Energy Act. The Coal Ash Act, as amended, (i) establishes a Coal Ash Management Commission (Coal Ash Commission) to oversee handling of coal ash within the state; (ii) prohibits construction of new and expansion of existing ash impoundments and use of existing impoundments at retired facilities; (iii) requires closure of ash impoundments at Duke Energy Progress' Asheville and Sutton stationsPlant and Duke Energy Carolinas' Riverbend and Dan River stations no later than August 1, 2019;2019 and Duke Energy Progress' Asheville Plant no later than August 1, 2022; (iv) requires dry disposal of fly ash at active plants, excluding the Asheville Plant, not retired by December 31, 2018; (v) requires dry disposal of bottom ash at active plants, excluding the Asheville Plant, by December 31, 2019, or retirement of active plants; (vi) requires all remaining ash impoundments in North Carolina to be categorized as high-risk, intermediate-risk or low-risk no later than December 31, 2015 by the North Carolina Department of Environment and Natural Resources (DENR) with the method of closure and timing to be based upon the assigned risk, with closure no later than December 31, 2029; (vii) establishes requirements to deal with groundwater and surface water impacts from impoundments; and (viii) enhances the level of regulation for structural fills utilizing coal ash. The Coal Ash Act includes a variance procedure for compliance deadlines and modification of requirements regarding structural fills and compliance boundaries. Provisions of the Coal Ash Act prohibit cost recovery in customer rates for unlawful discharge of ash basin waters occurring after January 1, 2014. The Coal Ash Act leaves the decision on cost recovery determinations related to closure of coal combustion residual (CCR) surface impoundments (ash basins or impoundments) to the normal ratemaking processes before utility regulatory commissions. Duke Energy has and will periodically submit to DENR site-specific coal ash impoundment closure plans or excavation plans in advance of closure plans. These plans and all associated permits must be approved by DENR before any excavation or closure work can begin.
In September 2014, Duke Energy Carolinas executed a consent agreement with the South Carolina Department of Health and Environmental Control (SCDHEC) requiring the excavation of an inactive ash basin and ash fill area at the W.S. Lee Steam Station. As part of this agreement, in December 2014, Duke Energy Carolinas filed an ash removal plan and schedule with SCDHEC. In April 2015, the federal CCR rules were published and Duke Energy Carolinas subsequently executed an agreement with the conservation groups Upstate Forever and Save Our Saluda requiring Duke Energy Carolinas to remediate all active and inactive ash storage areas at the W.S. Lee Steam Station. Coal-fired generation at W.S. Lee ceased in 2014 and unit 3 is being converted to natural gas. In July 2015, Duke Energy Progress executed a consent agreement with the SCDHEC requiring the excavation of an inactive ash fill area at the Robinson Plant within eight years. The Robinson Plant and W.S. Lee Station sites are required to be closed pursuant to the recently issued CCR rule and the provisions of these consent agreements are consistent with the federal CCR closure requirements.
Asset retirement obligations are recorded on the Duke Energy Carolinas and Duke Energy Progress Condensed Consolidated Balance Sheets at March 31,June 30, 2015 based upon the legal obligation for closure of coal ash basins and the disposal of related ash as a result of the Coal Ash Act and the agreement with SCDHEC. See Note 7 for additional information.

Coal Combustion Residuals
On April 17, 2015, the EPA published in the Federal RegistryRegister a rule to regulate the disposal of CCR from electric utilities as solid waste. The federal regulation classifies CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act.Act and allows beneficial use of CCRs with some restrictions. The regulation applies to all new and existing landfills, new and existing surface impoundments, structural fills and CCR piles. The rule establishes requirements regarding landfill design, structural integrity design and assessment criteria for surface impoundments, groundwater monitoring and protection procedures and other operational and reporting procedures to ensure the safe disposal and management of CCR. In addition to the requirements of the federal CCR regulation, CCR landfills and surface impoundments will continue to be independently regulated by most states. In accordance with ASC 410-20, Asset Retirement and Environmental Obligations - Asset Retirement Obligations, Duke Energy records an asset retirement obligation when it has a legal obligation to incur retirement costs associated with the retirement of a long-lived asset and the obligation can be reasonably estimated. 
Duke Energy Registrants impacted by the rule will recordCarolinas, Progress Energy, Duke Energy Progress, Duke Energy Ohio and Duke Energy Indiana recorded additional asset retirement obligation amounts in the second quarter of 2015. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of necessary and prudently incurred costs associated with Duke Energy’s regulated operations. See Note 7 for additional information.
LITIGATION
Duke Energy
Ash Basin Shareholder Derivative Litigation
Five shareholder derivative lawsuits were filed in Delaware Chancery Court relating to the release at Dan River and to the management of Duke Energy’s ash basins. On October 31, 2014, the five lawsuits were consolidated in a single proceeding titled "In Re Duke Energy Corporation Coal Ash Derivative Litigation." On December 2, 2014, plaintiffs filed a Corrected Verified Consolidated Shareholder Derivative Complaint (Consolidated Complaint). The Consolidated Complaint names as defendants several current and former Duke Energy officers and directors (collectively, the “Duke Energy Defendants”). Duke Energy is named as a nominal defendant.
The Consolidated Complaint alleges the Duke Energy Defendants breached their fiduciary duties to the company by failing to adequately oversee Duke Energy’s ash basins and that these breaches of fiduciary duty may have contributed to the incident at Dan River and continued thereafter. The lawsuit also asserts claims against the Duke Energy Defendants for corporate waste (relating to the money Duke Energy has spent and will spend as a result of the fines, penalties and coal ash removal) and unjust enrichment (relating to the compensation and director remuneration that was received despite these alleged breaches of fiduciary duty). The lawsuit seeks both injunctive relief against Duke Energy and restitution from the Duke Energy Defendants. On January 21, 2015, the Duke Energy Defendants filed a Motion to Stay and an alternative Motion to Dismiss.

On March 5, 2015, shareholder Judy Mesirov filed a shareholder derivative complaint (Mesirov Complaint) in North Carolina state court. The lawsuit, styled Mesirov v. Good, is similar to the consolidated derivative action pending in Delaware Chancery Court and was filed against the same current directors and former directors and officers as the Delaware litigation. Duke Energy Corporation, Duke Energy Progress and Duke Energy Carolinas are named as nominal defendants. The Mesirov Complaint alleges that the Duke Energy Board of Directors was aware of Clean Water Act (CWA) compliance issues and failures to maintain structures in ash basins, but that the Board of Directors did not require Duke Energy Carolinas and Duke Energy Progress to take action to remedy deficiencies. The Mesirov Complaint further alleges that the Board of Directors sanctioned activities to avoid compliance with the law by allowing improper influence of DENR to minimize regulation and by opposing previously anticipated citizen suit litigation. The Mesirov Complaint seeks corporate governance reforms and damages relating to costs associated with the Dan River release, remediation of ash basins that are out of compliance with the CWA and defending and payment of fines, penalties and settlements relating to criminal and civil investigations and lawsuits.
In addition to the above derivative complaints, Duke Energy has also received two shareholder litigation demand letters. On May 28, 2014, Duke Energy received a shareholder litigation demand letter sent on behalf of shareholder Mitchell Pinsly. The letter alleges that the members of the Board of Directors and certain officers breached their fiduciary duties by allowing the company to illegally dispose of and store coal ash pollutants. The letter demands that the Board of Directors take action to recover damages associated with those breaches of fiduciary duty; otherwise, the attorney will file a shareholder derivative action. By letter dated July 3, 2014, counsel for the shareholder was informed that the Board of Directors appointed a Demand Review Committee to evaluate the allegations in the Demand Letter.
On March 24, 2015, Duke Energy received a shareholder litigation demand letter sent on behalf of shareholder Saul Bresalier. The letter alleges that the members of the Board of Directors and certain officers breached their fiduciary duties in their management of the company'sDuke Energy's environmental practices, as well as in their decision-making relating to the leadership changes following the close of the Progress Energy merger in July 2012. The letter demands that the Board of Directors take action to recover damages associated with those alleged breaches of fiduciary duty; otherwise, the attorney will file a shareholder derivative action. In May 2015, counsel for the shareholder was informed that the matter had been referred to the Demand Review Committee.
It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with these matters.

Progress Energy Merger Shareholder Litigation
Duke Energy, the eleven11 members of the Board of Directors who were also members of the pre-merger Board of Directors (Legacy Duke Energy Directors) and certain Duke Energy officers are defendants in a purported securities class action lawsuit (Nieman v. Duke Energy Corporation, et al). This lawsuit consolidates three lawsuits originally filed in July 2012, and is pending in the United States District Court for the Western District of North Carolina. The plaintiffs allege federal Securities Act and Exchange Act claims based on allegations of materially false and misleading representations and omissions in the Registration Statement filed on July 7, 2011, and purportedly incorporated into other documents, all in connection with the post-merger change in Chief Executive Officer (CEO).
On August 15, 2014 the parties reached an agreement in principle to settle the litigation for an amount which, net of the expected proceeds of insurance policies, is not anticipated to have a material effect on the results of operations, cash flows or financial position of Duke Energy.litigation. On March 10, 2015, the parties filed a Stipulation of Settlement and a Motion for Preliminary Approval of the Settlement. The court issued an order for preliminary approval of the settlement on March 25, 2015. Under the terms of the agreement, Duke Energy agreed to pay $146 million to settle the claim. On April 22, 2015, Duke Energy made a payment of $25 million into the settlement escrow account. The remainder of $121 million was paid by insurers into the settlement escrow account. Notice has been sent to members of the class and a final approval hearing is expected to occur in the second half ofscheduled for August 12, 2015.
On May 31, 2013, the Delaware Chancery Court consolidated four shareholder derivative lawsuits filed in 2012. The Court also appointed a lead plaintiff and counsel for plaintiffs and designated the case as In Re Duke Energy Corporation Derivative Litigation. The lawsuit names as defendants the Legacy Duke Energy Directors. Duke Energy is named as a nominal defendant. The case alleges claims for breach of fiduciary duties of loyalty and care in connection with the post-merger change in CEO. The case is stayed pending resolution of the Nieman v. Duke Energy Corporation, et al. case in North Carolina.
Two shareholder Derivative Complaints, filed in 2012 in federal district court in Delaware, were consolidated as Tansey v. Rogers, et al. The case alleges claims for breach of fiduciary duty and waste of corporate assets, as well as claims under Section 14(a) and 20(a) of the Exchange Act. Duke Energy is named as a nominal defendant. Pursuant to an order entered on September 2, 2014, the court administratively closed this consolidated derivative action. The parties filed a status report with the court on December 1, 2014, and will continue to do so every six months thereafter until the Nieman v. Duke Energy Corporation, et al. case in North Carolina has been resolved.
It is not possible to estimate the maximum exposure of loss that may occur in connection with these lawsuits.

Price Reporting Cases
Five lawsuits were filed against a Duke Energy affiliate, Duke Energy Trading and Marketing, LLC, and other energy companies and remain pending in a consolidated, single federal court proceeding in Nevada. Each of these lawsuits contain similar claims that defendants allegedly manipulated natural gas markets by various means, including providing false information to natural gas trade publications and entering into unlawful arrangements and agreements in violation of the antitrust laws of the respective states. Plaintiffs seek damages in unspecified amounts.
On July 18, 2011, the judge granted a defendant’s motion for summary judgment in two of five cases. The U.S. Court of Appeals for the Ninth Circuit subsequently reversed the lower court’s decision. On April 21, 2015, the Supreme Court affirmed the U.S. Court of Appeals decision. The case will be remandedhas been reassigned to the same consolidated federal district court proceeding in Nevada for further proceedings.
It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with the remaining matters. However, based on Duke Energy’s past experiences with similar cases of this nature, it does not believe its exposure under these remaining matters is material.
Brazil Expansion Lawsuit
On August 9, 2011, the State of São Paulo sued Duke Energy International Geracao Paranapenema S.A. (DEIGP) in Brazilian state court. The lawsuit claims DEIGP is under a continuing obligation to expand installed generation capacity in the State of São Paulo by 15 percent pursuant to a stock purchase agreement under which DEIGP purchased generation assets from the state. On August 10, 2011, a judge granted an ex parte injunction ordering DEIGP to present a detailed expansion plan in satisfaction of the 15 percent obligation. DEIGP has previously taken a position the expansion obligation is no longer viable given changes that have occurred in the electric energy sector since privatization. DEIGP submitted its proposed expansion plan on November 11, 2011, but reserved objections regarding enforceability. In January 2013, DEIGP filed appeals in the federal courts regarding various procedural issues. A decision on the merits in the first instance court is pending. It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with this matter.
Brazil Generation
Record drought conditions in Brazil continue to impact Duke Energy International, Geracao Paranapanema S.A. (DEIGP) in 2015. In the midst of negotiations between the hydroelectric generators and the Brazilian federal government to find ways to mitigate the financial impact on these companies, Santo Antonio Energia (SAE), a large hydro generator, filed an independent lawsuit seeking financial relief in Brazilian federal court. In May 2015, SAE was granted an injunction by a Brazilian court limiting the financial impact of its declining hydroelectric dispatch to 95 percent of its guaranteed dispatch level. Following the court’s ruling in the SAE litigation, the Brazilian electricity dispatch authority (CCEE) announced that the electric system shortfall resulting from the court-ordered limitation of liability for SAE will be compensated on a pro-rata basis with contributions from all other hydroelectric generators in Brazil. In response, the Independent Power Producer Association (APINE), on behalf of the hydroelectric generators, filed a lawsuit against the Brazilian electricity regulatory agency seeking relief from exposure to their diminished dispatch levels similar to the relief previously granted SAE. On July 2, 2015, an injunction was granted in favor of APINE limiting the market exposure of DEIGP and other independent generators to 100 percent of the guaranteed dispatch level, until the merits of the lawsuit are determined. The decision is subject to appeal. It is not possible to predict the impact to Duke Energy, if any, from the outcome of these matters.
Duke Energy Carolinas and Duke Energy Progress
DENR State Enforcement Actions
In the first quarter of 2013, environmental organizations sent notices of intent to sue Duke Energy Carolinas and Duke Energy Progress related to alleged groundwater violations and CWA violations from coal ash basins at two of their coal-fired power plants in North Carolina. DENR filed enforcement actions against Duke Energy Carolinas and Duke Energy Progress alleging violations of water discharge permits and North Carolina groundwater standards. The case against Duke Energy Carolinas was filed in Mecklenburg County Superior Court. The case against Duke Energy Progress was filed in Wake County Superior Court. The cases are being heard before a single judge.
On October 4, 2013, Duke Energy Carolinas, Duke Energy Progress and DENR negotiated a proposed consent order covering these two plants. The consent order would have assessed civil penalties and imposed a compliance schedule requiring Duke Energy Carolinas and Duke Energy Progress to undertake monitoring and data collection activities toward making appropriate corrective action to address any substantiated violations. In light of the coal ash release that occurred at Dan River on February 2, 2014, on March 21, 2014, DENR withdrew its support of the consent orders and requested that the court proceed with the litigation.

On August 16, 2013, DENR filed an enforcement action against Duke Energy Carolinas and Duke Energy Progress related to their remaining plants in North Carolina, alleging violations of the CWA and violations of the North Carolina groundwater standards. The case against Duke Energy Carolinas was filed in Mecklenburg County Superior Court. The case against Duke Energy Progress was filed in Wake County Superior Court. Both of these cases have been assigned to the judge handling the enforcement actions discussed above. The SELC, on behalf of several environmental groups, has been permitted to intervene in these cases.
On July 10, 2015, Duke Energy Carolinas and Duke Energy Progress filed Motions for Partial Summary Judgment in the case on the basis that there is no longer either a genuine controversy or disputed material facts about the relief for seven of the 14 North Carolina plants with coal ash basins.

DENR Notices of Violation (NOV)
In August 2014, DENR issued a Notice of Violation (NOV)an NOV for alleged groundwater violations at Duke Energy Progress' L.V. Sutton plant.Plant. On March 10, 2015, DENR issued a civil penalty of approximately $25 million to Duke Energy Progress for environmental damages related to the groundwater contamination at the L.V. Sutton station.Plant. On April 9, 2015, Duke Energy Progress filed a Petition for Contested Case hearing in the Office of Administrative Hearings, which has been assigned to an Administrative Judge. Duke Energy Progress has appealed the penalty on the basis that DENR exceeded its statutory authority. Hearing is setscheduled for August 24,October 12, 2015.
In February 2015, DENR issued an NOV for alleged groundwater violations at Duke Energy Progress' Asheville plant.Plant. Duke Energy Progress has responded to DENR regarding this NOV. DENR has not taken any enforcement action for this NOV, but penalties may be assessed in the future.
It is not possible to predict any liability or estimate any damages Duke Energy Carolinas or Duke Energy Progress might incur in connection with these matters.
North Carolina Declaratory Judgment Action
On October 10, 2012, the SELC, on behalf of the same environmental groups that were permitted to challenge the consent decrees discussed above, filed a petition with the North Carolina Environmental Management Commission (EMC) asking for a declaratory ruling seeking to clarify the application of the state’s groundwater protection rules to coal ash basins. The petition sought to change the interpretation of regulations that permitted DENR to assess the extent, cause and significance of any groundwater contamination before ordering action to eliminate the source of contamination, among other issues. Duke Energy Carolinas and Duke Energy Progress were both permitted to intervene in the matter. On December 3, 2012, the EMC affirmed this interpretation of the regulations.
On March 6, 2014, the North Carolina State Court judge overturned the ruling of the EMC holding that in the case of groundwater contamination, DENR was required to issue an order to immediately eliminate the source of the contamination before an assessment of the nature, significance and extent of the contamination or the continuing damage to the groundwater was conducted. Duke Energy Carolinas, Duke Energy Progress and the EMC appealed the ruling in April 2014. On May 16, 2014, the North Carolina Court of Appeals denied a petition to stay the case during the appeal. On October 10, 2014, the parties were notified the case has been transferred to the NCSC. Oral argument was held on March 16, 2015. On June 11, 2015, the North Carolina Supreme Court issued its opinion in favor of Duke Energy Carolinas, Duke Energy Progress and the EMC and remanded the matter to the state court judge with instructions to dismiss the case.
Federal Citizens Suits
There are currently five cases filed in various North Carolina federal courts contending that the DENR state enforcement actions discussed above do not adequately address the issues raised in the notices of intent to sue related to the Riverbend, Sutton, Cape Fear, H.F. Lee and Buck plants.
On June 11, 2013, Catawba Riverkeeper Foundation, Inc. (Catawba Riverkeeper) filed a separate action in the United States Court for the Western District of North Carolina. The lawsuit contends the state enforcement action discussed above does not adequately address issues raised in Catawba Riverkeeper’s notice of intent to sue relating to the Riverbend plant.Steam Station. On April 11, 2014, the Court denied Catawba Riverkeeper’s objections to the Magistrate Judge’s recommendation that plaintiff’s case be dismissed as well as Duke Energy Carolinas’ motion to dismiss. The Court allowed limited discovery, after which Duke Energy Carolinas may file any renewed motions to dismiss.
On September 12, 2013, Cape Fear River Watch, Inc., Sierra Club and Waterkeeper Alliance filed a citizen suit in the Federal District Court for the Eastern District of North Carolina. The lawsuit alleges unpermitted discharges to surface water and groundwater violations at the Sutton plant.Plant. On June 9, 2014, the court granted Duke Energy Progress' request to dismiss the groundwater claims but rejected its request to dismiss the surface water claims. In response to a motion filed by the SELC, on August 1, 2014, the court modified the original June 9 order to dismiss only the plaintiff's federal law claim based on hydrologic connections at Sutton Lake. The claims related to the alleged state court violations of the permits are back in the case.
On September 3, 2014, three cases were filed by various environmental groups: (i) a citizen suit in the United States Court for the Middle District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the Cape Fear plant;Plant; (ii) a citizen suit in the United States Court for the Eastern District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the H.F. Lee plant;Plant; and (iii) a citizen suit in the United States Court for the Middle District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the Buck plant.Steam Station. Motions to Stay or Dismiss the proceedings were filed in each of the three cases. The proceedings related to Cape Fear and H.F. Lee have been stayed. A hearing was held August 5, 2015 on the motion relating to Buck.
It is not possible to predict whether Duke Energy Carolinas or Duke Energy Progress will incur any liability or to estimate the damages, if any, they might incur in connection with these matters.

Commercial Portfolio has a revolving credit agreement (RCA) which was used to support the operations of the nonregulated Midwest generation business. Interest expense associated with the RCA was allocated to discontinued operations. No other interest expense related to corporate level debt was allocated to discontinued operations.
Duke Energy Ohio had a power purchase agreement with the Disposal Group for a portion of its standard service offer (SSO) supply requirement. The agreement and the SSO expired in May 2015. Duke Energy will also provide, and receive reimbursement for, transition services provided to Dynegy for a period of up to 12 months. The continuing cash flows are not considered direct cash flows and are not expected to be material. Duke Energy or Duke Energy Ohio will not significantly influence the operations of the Disposal Group during the transition service period.
See Notes 4 and 5 for a discussion of contingencies related to the Disposal Group that are retained by Duke Energy Ohio subsequent to the sale.
3. BUSINESS SEGMENTS
Duke Energy evaluates segment performance based on segment income. Segment income is defined as income from continuing operations net of income attributable to noncontrolling interests. Segment income, as discussed below, includes intercompany revenues and expenses that are eliminated in the Condensed Consolidated Financial Statements. Certain governance costs are allocated to each segment. In addition, direct interest expense and income taxes are included in segment income.
Operating segments are determined based on information used by the chief operating decision-maker in deciding how to allocate resources and evaluate the performance of the business.
Products and services are sold between affiliate companies and reportable segments of Duke Energy at cost. Segment assets presented in the following tables exclude all intercompany assets.

DUKE ENERGY
Duke Energy has the following reportable operating segments: Regulated Utilities, International Energy and Commercial Portfolio.
RegulatedUtilities conducts electric and natural gas operations that are substantially all regulated and, accordingly, qualify for regulatory accounting treatment. These operations are primarily conducted through the Subsidiary Registrants and are subject to the rules and regulations of the FERC, NRC, NCUC, PSCSC, FPSC, PUCO, IURC and KPSC.
International Energy principally operates and manages power generation facilities and engages in sales and marketing of electric power, natural gas and natural gas liquids outside the U.S. Its activities principally relate to power generation in Latin America. Additionally, International Energy owns a 25 percent interest in National Methanol Company (NMC), a large regional producer of methyl tertiary butyl ether (MTBE) located in Saudi Arabia. The investment in NMC is accounted for under the equity method of accounting.
Commercial Portfolio builds, develops and operates wind and solar renewable generation and energy transmission projects throughout the continental U.S. The segment was renamed as a result of the sale of the nonregulated Midwest generation business, as discussed in Note 2. For periods subsequent to the sale, beginning in the second quarter of 2015, certain immaterial results of operations and related assets previously presented in the Commercial Portfolio segment are presented in Regulated Utilities and Other.
Theremainder of Duke Energy’s operations is presented as Other, which is primarily comprised of unallocated corporate interest expense, unallocated corporate costs, contributions to The Duke Energy Foundation, and the operations of Duke Energy’s wholly owned captive insurance subsidiary, Bison Insurance Company Limited (Bison).

DUKE ENERGY OHIO
All of Duke Energy Ohio’s revenues are generated domestically and its long-lived assets are all in the U.S.
Duke Energy Ohio had two reportable operating segments until the sale of the nonregulated Midwest generation business, Regulated Utilities and Commercial Portfolio. Commercial Portfolio no longer qualifies as a Duke Energy Ohio reportable operating segment as a result of the sale. Refer to Note 2 for further information about the sale. Therefore, for periods subsequent to the sale, beginning in the second quarter of 2015, all of the remaining assets and related results of operations previously presented in Commercial Portfolio are presented in Regulated Utilities and Other.
Regulated Utilities transmits and distributes electricity in portions of Ohio and generates, distributes and sells electricity in portions of Kentucky. Regulated Utilities also transports and sells natural gas in portions of Ohio and northern Kentucky. It conducts operations primarily through Duke Energy Ohio and its wholly owned subsidiary, Duke Energy Kentucky.
Other is primarily comprised of governance costs allocated by its parent, Duke Energy, and revenues and expenses related to Duke Energy Ohio's contractual arrangement to buy power from OVEC's power plants. Duke Energy Ohio had no intersegment revenues for the six months ended June 30, 2015 or 2014. For additional information on related party transactions refer to Note 9.

4. REGULATORY MATTERS
RATE RELATED INFORMATION
The NCUC, PSCSC, FPSC, IURC, PUCO and KPSC approve rates for retail electric and natural gas services within their respective states. The FERC approves rates for electric sales to wholesale customers served under cost-based rates (excluding Ohio and Indiana), as well as sales of transmission service.
Duke Energy Carolinas
William States Lee Combined Cycle Facility
On April 9, 2014, the PSCSC granted Duke Energy Carolinas and North Carolina Electric Membership Corporation (NCEMC) a Certificate of Environmental Compatibility and Public Convenience and Necessity for the construction and operation of a 750 MW combined-cycle natural gas-fired generating plant at Duke Energy Carolinas' existing William States Lee Generating Station in Anderson, South Carolina. Duke Energy Carolinas began construction in July 2015, and estimates a cost to build of $600 million for its share of the facility, including allowance for funds used during construction (AFUDC). The project is expected to be commercially available in late 2017. NCEMC will own approximately 13 percent of the project. On July 3, 2014, the South Carolina Coastal Conservation League and Southern Alliance for Clean Energy jointly filed a Notice of Appeal with the Court of Appeals of South Carolina seeking the court's review of the PSCSC's decision. The case has been fully briefed and is pending in the Court of Appeals. Duke Energy Carolinas cannot predict the outcome of this matter.
Duke Energy Progress
Sutton Black Start Combustion Turbine CPCN
On April 15, 2015, Duke Energy Progress filed a certificate of public convenience and necessity (CPCN) application with the NCUC for approval to construct an 84 MW black start combustion turbine (CT) project at the existing Sutton Plant (Sutton Black Start CT Project). The Sutton Black Start CT Project would replace three existing CTs with total capacity of 61 MW with two new 42 MW CT units with black start and fast start capability. In addition to peaking system capacity, the Sutton Black Start CT Project will provide regional black start capability and tertiary backup power services for the Brunswick Nuclear Plant. In June 2015, the Public Staff of the NCUC recommended the NCUC approve Duke Energy Progress' application. On August 3, 2015, the NCUC issued an order granting the application and requiring annual construction and cost progress reports.
Western Carolinas Modernization Plan
In May 2015, Duke Energy Progress announced a $1.1 billion plan to modernize the Western Carolinas energy system. The plan includes retiring the Asheville coal-fired plant, building a 650 MW combined-cycle natural gas power plant and installing solar generation at the site, building new transmission lines and upgrading area substations. These investments will be made within the next five years in North Carolina and South Carolina. Duke Energy is also working with the local natural gas distribution company to upgrade an existing natural gas pipeline to serve the natural gas plant. On June 24, 2015, the North Carolina governor signed into law the Mountain Energy Act of 2015 (Mountain Energy Act) which provides for an expedited CPCN process for the proposed Asheville combined-cycle project and extends certain North Carolina Coal Ash Management Act of 2014 (Coal Ash Act) deadlines for the coal ash basin at the Asheville Plant site. The plan requires various approvals including regulatory approvals in North Carolina and South Carolina.
The carrying value of the 376 MW Asheville coal-fired plant, including associated ash basin closure costs, of $460 million is included in Generation facilities to be retired, net on Duke Energy Progress' Condensed Consolidated Balance Sheet as of June 30, 2015.
Duke Energy Florida
FERC Transmission Return on Equity Complaint
Seminole Electric Cooperative, Inc. and Florida Municipal Power Agency filed multiple complaints with the FERC alleging Duke Energy Florida's current rate of return on equity in transmission formula rates of 10.8 percent is unjust and unreasonable. The latest complaint, filed on August 12, 2014, claims the rate of return on equity should be reduced to 8.69 percent. The FERC consolidated all complaints for the purposes of settlement, hearing and decision. On July 21, 2015, the parties filed with the FERC for approval of a settlement agreement under which (i) Duke Energy Florida will pay a total of $14.1 million as refunds for all periods through December 31, 2014, (ii) the rate of return on equity will be 10 percent effective January 1, 2015, and (iii) none of the parties will seek a change in the rate of return on equity prior to January 1, 2018.
Citrus County Combined Cycle Facility
On October 2, 2014, the FPSC granted Duke Energy Florida a Determination of Need for the construction of a 1,640 MW combined-cycle natural gas plant in Citrus County, Florida. On May 5, 2015, the Florida Department of Environmental Protection approved Duke Energy Florida's Site Certification Application. The facility is expected to be commercially available in 2018 at an estimated cost of $1.5 billion, including AFUDC. Additional environmental and governmental approvals will be sought for the Citrus County project.

Purchase of Osprey Energy Center
In December 2014, Duke Energy Florida and Osprey Energy Center, LLC, a wholly owned subsidiary of Calpine Corporation (Calpine), entered into an Asset Purchase and Sale Agreement for the purchase of a 599 MW combined-cycle natural gas plant in Auburndale, Florida (Osprey Plant acquisition) for approximately $166 million. On January 30, 2015, Duke Energy Florida petitioned the FPSC requesting a determination that the Osprey Plant acquisition or, alternatively, the construction of a 320 MW combustion turbine at its existing Suwannee generating facility (Suwannee project) with an estimated cost of $197 million, is the most cost-effective generation alternative to meet Duke Energy Florida's remaining generation need prior to 2018. On July 21, 2015, the FPSC approved the Osprey Plant acquisition as the most cost-effective alternative and an order is expected in August 2015. On July 24, 2015, the FERC issued an order approving the Osprey Plant acquisition. Closing of the acquisition is contingent upon the expiration of the Hart Scott Rodino waiting period and is expected to occur by the first quarter of 2017 upon the expiration of an existing Power Purchase Agreement between Calpine and Duke Energy Florida.
Crystal River Unit 3
On May 22, 2015, Duke Energy Florida petitioned the FPSC for approval to include in base rates the revenue requirement for the Crystal River Unit 3 Regulatory asset as authorized by the 2013 Revised and Restated Stipulation and Settlement Agreement (2013 Agreement). The value of the Crystal River Unit 3 Regulatory asset to be recovered is projected to be $1.298 billion at December 31, 2015. Based upon this projected value, the initial annual revenue requirement is estimated to be $170 million. 
In June 2015, the Governor of Florida signed into law legislation to allow utilities to petition for a financing order for securitization of certain retired nuclear generation assets. On July 27, 2015, Duke Energy Florida petitioned the FPSC for a financing order to finance the Crystal River Unit 3 Regulatory asset with low-cost securities. If the FPSC issues an acceptable financing order and Duke Energy Florida issues the bonds, securitization would replace the base rate recovery methodology established in the 2013 Agreement described above, and would result in a lower rate impact to customers. The annual revenue requirement with securitization, subject to changes in assumed interest rates and timing of issuance of the securitization bonds, is estimated to be approximately $100 million. The FPSC is expected to hold a hearing on both the Crystal River Unit 3 Regulatory asset filing and the securitization filing in October 2015. Duke Energy Florida cannot predict the outcome of this matter.
Levy Nuclear Project
On April 16, 2015, the FPSC approved Duke Energy Florida’s petition to cease collection of the Levy Nuclear Project fixed charge beginning with the first billing cycle in May. Duke Energy Florida also sought approval to defer collection of the $54 million regulatory asset until litigation with Westinghouse Electric Co. concludes. The FPSC found that it was unnecessary to act on the request, finding that its previous order requiring the downward adjustment in projected costs primarily affected the timing of when the fixed charge would end, but that it did not disallow recovery of any costs previously determined to be prudent.
Duke Energy Ohio
2014 Electric Security Plan
In April 2015, the PUCO modified and approved Duke Energy Ohio's proposed ESP, with a three-year term and an effective date of June 1, 2015. The PUCO approved a competitive procurement process for SSO load, a distribution capital investment rider, and a tracking mechanism for incremental distribution expenses caused by major storms. The PUCO order also approved a placeholder tariff for a price stabilization rider, but denied Duke Energy Ohio's specific request to include OVEC in the rider at this time; however, the order allows Duke Energy Ohio to submit additional information to request recovery in the future. On May 4, 2015, Duke Energy Ohio filed an application for rehearing requesting the PUCO to modify or amend certain aspects of the order. On May 14, 2015, Duke Energy Ohio completed a competitive bidding process to procure a portion of the supply for its SSO load for the term of the ESP. The PUCO approved the results on May 15, 2015. On May 28, 2015, the PUCO granted all applications for rehearing filed in the case for future consideration. Duke Energy Ohio cannot predict the outcome of this matter.
2012 Natural Gas Rate Case
On November 13, 2013, the PUCO issued an order approving a settlement among Duke Energy Ohio, the PUCO Staff and intervening parties (the Gas Settlement). The Gas Settlement provided for (i) no increase in base rates for natural gas distribution service and (ii) a return on equity of 9.84 percent. The Gas Settlement provided for a subsequent hearing on Duke Energy Ohio’s request for rider recovery of environmental remediation costs associated with its former manufactured gas plant (MGP) sites. The PUCO authorized Duke Energy Ohio to recover $56 million, excluding carrying costs, of environmental remediation costs. The MGP rider became effective in April 2014 for a five-year period. On March 31, 2014, Duke Energy Ohio filed an application with the PUCO to adjust the MGP rider for investigation and remediation costs incurred in 2013.
Certain consumer groups appealed the PUCO’s decision authorizing the MGP rider to the Ohio Supreme Court and asked the court to stay implementation of the PUCO’s order and collections under the MGP rider pending their appeal. The Ohio Supreme Court granted the motion to stay and subsequently required the posting of a bond to effectuate the stay. When the bond was not posted, the PUCO approved Duke Energy Ohio’s request, in January 2015, to reinstate collections under the MGP rider and Duke Energy Ohio resumed billings. Amounts collected prior to the suspension of the rider were immaterial. On March 31, 2015, Duke Energy Ohio filed an application to adjust the MGP rider to recover remediation costs incurred in 2014. Duke Energy Ohio cannot predict the outcome of the appeal of this matter.
Regional Transmission Organization (RTO) Realignment
Duke Energy Ohio, including Duke Energy Kentucky, transferred control of its transmission assets from Midcontinent Independent System Operator, Inc. (MISO) to PJM Interconnection, LLC (PJM), effective December 31, 2011.

On December 22, 2010, the KPSC approved Duke Energy Kentucky’s request to effect the RTO realignment, subject to a commitment not to seek double recovery in a future rate case of the transmission expansion fees that may be charged by MISO and PJM in the same period or overlapping periods.
On May 25, 2011, the PUCO approved a settlement between Duke Energy Ohio, Ohio Energy Group, the Office of Ohio Consumers’ Counsel and the PUCO Staff related to Duke Energy Ohio’s recovery of certain costs of the RTO realignment via a non-bypassable rider. Duke Energy Ohio is allowed to recover all MISO Transmission Expansion Planning (MTEP) costs, including but not limited to Multi Value Project (MVP) costs, directly or indirectly charged to Ohio customers. Duke Energy Ohio also agreed to vigorously defend against any charges for MVP projects from MISO.
Upon its exit from MISO on December 31, 2011, Duke Energy Ohio recorded a liability for its exit obligation and share of MTEP costs, excluding MVP. This liability was recorded within Other in Current liabilities and Other in Deferred credits and other liabilities on Duke Energy Ohio’s Condensed Consolidated Balance Sheets.
As of June 30, 2015, Duke Energy Ohio had recorded obligations of $93 million related to its withdrawal from MISO and a Regulatory asset of $73 million recorded on the Condensed Consolidated Balance Sheets. MTEP costs billed by MISO are recovered by Duke Energy Ohio through a non-bypassable rider.
MVP. MISO approved 17 MVP proposals prior to Duke Energy Ohio’s exit from MISO on December 31, 2011. Construction of these projects is expected to continue through 2020. Costs of these projects, including operating and maintenance costs, property and income taxes, depreciation and an allowed return, are allocated and billed to MISO transmission owners.
On December 29, 2011, MISO filed a tariff with the FERC providing for the allocation of MVP costs to a withdrawing owner based on monthly energy usage. The FERC set for hearing (i) whether MISO’s proposed cost allocation methodology to transmission owners who withdrew from MISO prior to January 1, 2012 is consistent with the tariff at the time of their withdrawal from MISO, and, (ii) if not, what the amount of and methodology for calculating any MVP cost responsibility should be. On July 16, 2013, a FERC Administrative Law Judge (ALJ) issued an initial decision. Under this initial decision, Duke Energy Ohio would be liable for MVP costs. Duke Energy Ohio filed exceptions to the initial decision, requesting the FERC overturn the ALJ’s decision. After reviewing the initial decision, along with all exceptions and responses filed by the parties, the FERC will issue a final decision. Duke Energy Ohio fully intends to appeal to the federal court of appeals if the FERC affirms the ALJ’s decision. Duke Energy Ohio cannot predict the outcome of these proceedings.
In 2012, MISO estimated Duke Energy Ohio’s MVP obligation over the period from 2012 to 2071 at $2.7 billion, on an undiscounted basis. The estimated obligation is subject to great uncertainty including the ultimate cost of the projects, the annual costs of operations and maintenance, taxes and return over the project lives, the number of years in service for the projects and the allocation to Duke Energy Ohio.
Any liability related to the MISO MVP matter or MTEP costs attributable to the Disposal Group was not transferred to Dynegy upon the sale of the nonregulated Midwest generation business.
FERC Transmission Return on Equity and MTEP Cost Settlement
On October 14, 2011, Duke Energy Ohio and Duke Energy Kentucky submitted with the FERC proposed modifications to the PJM Interconnection Open Access Transmission Tariff pertaining to recovery of the transmission revenue requirement as PJM transmission owners. The filing was made in connection with Duke Energy Ohio's and Duke Energy Kentucky's move from MISO to PJM effective January 1, 2012. On April 24, 2012, the FERC issued an order accepting the proposed filing effective January 1, 2012, except that the order denied a request to recover certain costs associated with the move from MISO to PJM without prejudice to the right to submit another filing seeking such recovery and including certain additional evidence, and set the rate of return on equity of 12.38 percent for settlement and hearing. On April 16, 2015, the FERC approved a settlement agreement between Duke Energy Ohio, Duke Energy Kentucky and six PJM transmission customers with load in the Duke Energy Ohio and Duke Energy Kentucky zone. The principal terms of the settlement agreement are that, effective upon the date of FERC approval, (i) the return on equity for wholesale transmission service is reduced to 11.38 percent, (ii) the settling parties agreed not to seek a change in the return on equity that would be effective prior to June 1, 2017, and (iii) Duke Energy Ohio and Duke Energy Kentucky will recover 30 percent of the wholesale portion of costs arising from their obligation to pay any portion of the costs of projects included in any MTEP that was approved prior to the date of Duke Energy Ohio's and Duke Energy Kentucky's integration into PJM.
Duke Energy Indiana
Edwardsport Integrated Gasification Combined Cycle (IGCC) Plant
On November 20, 2007, the IURC granted Duke Energy Indiana a CPCN for the construction of the Edwardsport IGCC Plant. The Citizens Action Coalition of Indiana, Inc., Sierra Club, Inc., Save the Valley, Inc., and Valley Watch, Inc. (collectively, the Joint Intervenors) were intervenors in several matters related to the Edwardsport IGCC Plant. The Edwardsport IGCC Plant was placed in commercial operation in June 2013. Costs for the Edwardsport IGCC Plant are recovered from retail electric customers via a tracking mechanism, the IGCC rider. Updates to the IGCC rider are filed semi-annually.
The ninth semi-annual IGCC rider order was appealed by the Joint Intervenors. On September 8, 2014, the Indiana Court of Appeals remanded the IURC order in the ninth IGCC rider proceeding back to the IURC for further findings. On February 25, 2015, the IURC issued a new order upholding its prior decision and provided additional detailed findings. Joint Intervenors have appealed this remand order to the Indiana Court of Appeals.
The 10th semi-annual IGCC rider order was also appealed by the Joint Intervenors. On August 21, 2014 the Indiana Court of Appeals affirmed the IURC order in the 10th IGCC rider proceeding and on October 29, 2014 denied the Joint Intervenors' request for rehearing. The Joint Intervenors requested the Indiana Supreme Court to review the decision, which was denied on April 23, 2015, concluding the appeal.

An order on the 11th semi-annual IGCC rider is currently pending. The 12th and 13th semi-annual IGCC riders were combined for hearings which were held in February 2015 and an order is currently pending. Issues in this proceeding include whether the IGCC plant was properly declared in service for ratemaking purposes in June 2013 and the operational performance of the plant during its initial 10 months of operations. Duke Energy Indiana has filed the 14th and 15th semi-annual IGCC rider proceedings, with a hearing scheduled in November 2015.
On April 2, 2014, the IURC established a subdocket to Duke Energy Indiana’s current fuel adjustment clause proceeding. In this fuel adjustment subdocket, the IURC intends to review underlying causes for net negative generation amounts at the Edwardsport IGCC Plant during the period September through November 2013. Duke Energy Indiana contends the net negative generation is related to the consumption of fuel and auxiliary power when the plant was in start-up or off line. In addition to the OUCC, the Duke Energy Indiana Industrial Group, Nucor Steel-Indiana, Steel Dynamics, Inc., and the Joint Intervenors are parties to the subdocket. The IURC has deferred the fuel adjustment subdocket until resolution of the 12th and 13th semi-annual IGCC rider proceedings. In addition, although the IURC approved fuel adjustment clause recovery for the period December 2013 through March 2014, it determined such fuel costs reasonably related to the operational performance of the Edwardsport IGCC Plant shall be subject to refund pending the outcome of the 12th and 13th semi-annual IGCC riders.
On August 6, 2015, the IURC granted a motion to defer ruling on all pending matters until September 15, 2015 to allow time for settlement discussions. The Commission is expected to proceed with issuance of an order if the parties do not reach a settlement agreement. Duke Energy Indiana cannot predict the outcome of the fuel adjustment clause proceedings or pending and future IGCC rider proceedings.
FERC Transmission Return on Equity Complaint
Customer groups have filed with the FERC complaints against MISO and its transmission-owning members, including Duke Energy Indiana, alleging, among other things, that the current base rate of return on equity earned by MISO transmission owners of 12.38 percent is unjust and unreasonable. The latest complaint, filed on February 12, 2015, claims the base rate of return on equity should be reduced to 8.67 percent and requests a consolidation of complaints. On January 5, 2015, the FERC issued an order accepting the MISO transmission owners 0.50 percent adder to the base rate of return on equity based on participation in an RTO subject to it being applied to a return on equity that is shown to be just and reasonable in the pending return on equity complaint. Settlement procedures in the base return on equity proceeding were terminated and a hearing is scheduled for August 17, 2015. Duke Energy Indiana cannot predict the outcome of this matter.
Grid Infrastructure Improvement Plan
On August 29, 2014, Duke Energy Indiana filed a seven-year grid infrastructure improvement plan with the IURC with an estimated cost of $1.9 billion, focusing on the reliability, integrity and modernization of the transmission and distribution system. In May 2015, the IURC denied the proposal due to an insufficient level of detailed projects and cost estimates in the plan. Duke Energy Indiana is evaluating the order and plans to file a revised infrastructure improvement plan by the end of 2015.
OTHER REGULATORY MATTERS
Atlantic Coast Pipeline
On September 2, 2014, Duke Energy, Dominion Resources (Dominion), Piedmont Natural Gas and AGL Resources announced the formation of a company, Atlantic Coast Pipeline, LLC (ACP), to build and own the proposed Atlantic Coast Pipeline (the pipeline), a 550-mile interstate natural gas pipeline. The pipeline is designed to meet the needs identified in requests for proposals by Duke Energy Carolinas, Duke Energy Progress and Piedmont Natural Gas. Dominion will build and operate the pipeline and will own 45 percent. Duke Energy will have a 40 percent ownership interest in ACP through its Commercial Portfolio segment. The remaining share will be owned by Piedmont Natural Gas and AGL Resources. Duke Energy Carolinas and Duke Energy Progress, among others, will be customers of the pipeline. Purchases will be made under several 20-year supply contracts, subject to state regulatory approval. In October 2014, the NCUC and PSCSC approved the Duke Energy Carolinas and Duke Energy Progress requests to enter into certain affiliate agreements, pay compensation to ACP and to grant a waiver of certain Code of Conduct provisions relating to contractual and jurisdictional matters. The project will require FERC approval, which ACP will seek to secure by summer 2016. The estimated in-service date of the pipeline is late 2018.
Sabal Trail Transmission, LLC Pipeline
On May 4, 2015, Duke Energy acquired a 7.5 percent ownership interest from Spectra Energy in the proposed 500-mile Sabal Trail natural gas pipeline. Spectra Energy will continue to own 59.5 percent of the pipeline and NextEra Energy will own the remaining 33 percent of the pipeline. The pipeline will traverse Alabama, Georgia and Florida to meet rapidly growing demand for natural gas in those states. The primary customers of the pipeline, Duke Energy Florida and Florida Power & Light Company, have each contracted to buy pipeline capacity for 25-year initial terms. The pipeline, scheduled to begin service in 2017, requires federal and other regulatory approvals. 
East Bend Station
On December 30, 2014, Duke Energy Ohio acquired The Dayton Power and Light Company's (DP&L) 31 percent interest in East Bend Station for approximately $12.4 million. The purchase price, in accordance with FERC guidelines, was reflected with the net purchase amount as an increase to property, plant and equipment as of December 31, 2014 and with the DP&L's historical original cost as an increase to property, plant and equipment and accumulated depreciation as of June 30, 2015.

NC WARN FERC Complaint
On December 16, 2014, North Carolina Waste Awareness and Reduction Network filed a complaint with the FERC against Duke Energy Carolinas and Duke Energy Progress that alleged (i) Duke Energy Carolinas and Duke Energy Progress manipulated the electricity market by constructing costly and unneeded generation facilities leading to unjust and unreasonable rates; (ii) Duke Energy Carolinas and Duke Energy Progress failed to comply with Order 1000 by not effectively connecting their transmission systems with neighboring utilities which also have excess capacity; (iii) the plans of Duke Energy Carolinas and Duke Energy Progress for unrealistic future growth lead to unnecessary and expensive generating plants; (iv) the FERC should investigate the practices of Duke Energy Carolinas and Duke Energy Progress and the potential benefits of having them enter into a regional transmission organization; and (v) the FERC should force Duke Energy Carolinas and Duke Energy Progress to purchase power from other utilities rather than construct wasteful and redundant power plants. NC WARN also filed a copy of the complaint with the PSCSC on January 6, 2015. In April 2015, the FERC and the PSCSC issued separate orders dismissing the NC WARN petition. On May 14, 2015, NC WARN filed with FERC a motion for reconsideration.
Potential Coal Plant Retirements
The Subsidiary Registrants periodically file Integrated Resource Plans (IRP) with their state regulatory commissions. The IRPs provide a view of forecasted energy needs over a long term (10 to 20 years), and options being considered to meet those needs. Recent IRPs filed by the Subsidiary Registrants included planning assumptions to potentially retire certain coal-fired generating facilities in North Carolina, Florida and Indiana earlier than their current estimated useful lives. These facilities do not have the requisite emission control equipment, primarily to meet United States Environmental Protection Agency (EPA) regulations recently approved or proposed.
The table below contains the net carrying value of generating facilities planned for retirement or included in recent IRPs as evaluated for potential retirement due to a lack of requisite environmental control equipment. Dollar amounts in the table below are included in Net property, plant and equipment on the Condensed Consolidated Balance Sheets.

Duke Energy Indiana committed to retire or convert the Wabash River Units 2 through 5 by June 2018 in conjunction with a settlement agreement associated with the Edwardsport air permit.
In addition to evaluations based on the extent facilities are equipped to comply with environmental regulations, Duke Energy continually monitors and evaluates the appropriate generation mix and fuel diversity for its generation fleet when making retirement decisions. Duke Energy Carolinas is evaluating the potential retirement of coal-fired generating units with a net carrying value of approximately $110 million, excluding capitalized asset retirement costs related to closure of ash basins, included in Net property, plant and equipment on the Condensed Consolidated Balance Sheets. These generating units are not included in the table above.
Duke Energy continues to evaluate the potential need to retire generating facilities earlier than the current estimated useful lives, and plans to seek regulatory recovery, as necessary, for amounts that would not be otherwise recovered when any of these assets are retired. However, such recovery, including recovery of carrying costs on remaining book values, could be subject to future regulatory approvals and therefore cannot be assured.
Refer to the "Western Carolinas Modernization Plan" discussion above for details of planned retirements for Duke Energy Progress.
5. COMMITMENTS AND CONTINGENCIES

Remediation Activities
The Duke Energy Registrants are responsible for environmental remediation at various contaminated sites. These include some properties that are part of ongoing operations and sites formerly owned or used by Duke Energy entities. These sites are in various stages of investigation, remediation and monitoring. Managed in conjunction with relevant federal, state and local agencies, activities vary with site conditions and locations, remediation requirements, complexity and sharing of responsibility. If remediation activities involve joint and several liability provisions, strict liability, or cost recovery or contribution actions, the Duke Energy Registrants could potentially be held responsible for contamination caused by other potentially responsible parties, and may also benefit from insurance policies or contractual indemnities that cover some or all cleanup costs. Liabilities are recorded when losses become probable and are reasonably estimable. The total costs that may be incurred cannot be estimated because the extent of environmental impact, allocation among potentially responsible parties, remediation alternatives and/or regulatory decisions have not yet been determined. Additional costs associated with remediation activities are likely to be incurred in the future and could be significant. Costs are typically expensed as Operation, maintenance and other in the Condensed Consolidated Statements of Operations unless regulatory recovery of the costs is deemed probable.
The following tables contain information regarding reserves for probable and estimable costs related to the various environmental sites. These reserves are recorded in Other within Deferred Credits and Other Liabilities on the Condensed Consolidated Balance Sheets.

North Carolina and South Carolina Ash Basins
On February 2, 2014, a break in a stormwater pipe beneath an ash basin at Duke Energy Carolinas’ retired Dan River Steam Station caused a release of ash basin water and ash into the Dan River. On February 8, 2014, a permanent plug was installed in the stormwater pipe, stopping the release of materials into the river. Duke Energy Carolinas estimates 30,000 to 39,000 tons of ash and 24 million to 27 million gallons of basin water were released into the river. In July 2014, Duke Energy completed remediation work identified by the EPA and continues to cooperate with the EPA's civil enforcement process. Total repairs and remediation expenses incurred by Duke Energy Carolinas related to the release were approximately $24 million. No additional expenses were recorded in 2015. Duke Energy Carolinas will not seek recovery of these costs from ratepayers. See the "Litigation" section below for additional information on litigation, investigations and enforcement actions related to ash basins, including the Memorandum of Plea Agreement (Plea Agreements) in connection to the North Carolina Ash Basin Grand Jury InvestigationInvestigation. Other costs related to the Dan River release, including pending or future state or federal civil enforcement proceedings, future regulatory directives, natural resources damages, additional pending litigation, future claims or litigation, and long-term environmental impact costs cannot be reasonably estimated at this time.

On September 20, 2014, the Coal Ash Act became law and was amended on June 24, 2015, by the Mountain Energy Act. The Coal Ash Act, as amended, (i) establishes a Coal Ash Management Commission (Coal Ash Commission) to oversee handling of coal ash within the state; (ii) prohibits construction of new and expansion of existing ash impoundments and use of existing impoundments at retired facilities; (iii) requires closure of ash impoundments at Duke Energy Progress' Sutton Plant and Duke Energy Carolinas' Riverbend and Dan River stations no later than August 1, 2019 and Duke Energy Progress' Asheville Plant no later than August 1, 2022; (iv) requires dry disposal of fly ash at active plants, excluding the Asheville Plant, not retired by December 31, 2018; (v) requires dry disposal of bottom ash at active plants, excluding the Asheville Plant, by December 31, 2019, or retirement of active plants; (vi) requires all remaining ash impoundments in North Carolina to be categorized as high-risk, intermediate-risk or low-risk no later than December 31, 2015 by the North Carolina Department of Environment and Natural Resources (DENR) with the method of closure and timing to be based upon the assigned risk, with closure no later than December 31, 2029; (vii) establishes requirements to deal with groundwater and surface water impacts from impoundments; and (viii) enhances the level of regulation for structural fills utilizing coal ash. The Coal Ash Act includes a variance procedure for compliance deadlines and modification of requirements regarding structural fills and compliance boundaries. Provisions of the Coal Ash Act prohibit cost recovery in customer rates for unlawful discharge of ash basin waters occurring after January 1, 2014. The Coal Ash Act leaves the decision on cost recovery determinations related to closure of coal combustion residual (CCR) surface impoundments (ash basins or impoundments) to the normal ratemaking processes before utility regulatory commissions. Duke Energy has and will periodically submit to DENR site-specific coal ash impoundment closure plans or excavation plans in advance of closure plans. These plans and all associated permits must be approved by DENR before any excavation or closure work can begin.
In September 2014, Duke Energy Carolinas executed a consent agreement with the South Carolina Department of Health and Environmental Control (SCDHEC) requiring the excavation of an inactive ash basin and ash fill area at the W.S. Lee Steam Station. As part of this agreement, in December 2014, Duke Energy Carolinas filed an ash removal plan and schedule with SCDHEC. In April 2015, the federal CCR rules were published and Duke Energy Carolinas subsequently executed an agreement with the conservation groups Upstate Forever and Save Our Saluda requiring Duke Energy Carolinas to remediate all active and inactive ash storage areas at the W.S. Lee Steam Station. Coal-fired generation at W.S. Lee ceased in 2014 and unit 3 is being converted to natural gas. In July 2015, Duke Energy Progress executed a consent agreement with the SCDHEC requiring the excavation of an inactive ash fill area at the Robinson Plant within eight years. The Robinson Plant and W.S. Lee Station sites are required to be closed pursuant to the recently issued CCR rule and the provisions of these consent agreements are consistent with the federal CCR closure requirements.
Asset retirement obligations are recorded on the Duke Energy Carolinas and Duke Energy Progress Condensed Consolidated Balance Sheets at June 30, 2015 based upon the legal obligation for closure of coal ash basins and the disposal of related ash as a result of the Coal Ash Act and the agreement with SCDHEC. See Note 7 for additional information.
Coal Combustion Residuals
On April 17, 2015, the EPA published in the Federal Register a rule to regulate the disposal of CCR from electric utilities as solid waste. The federal regulation classifies CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act and allows beneficial use of CCRs with some restrictions. The regulation applies to all new and existing landfills, new and existing surface impoundments, structural fills and CCR piles. The rule establishes requirements regarding landfill design, structural integrity design and assessment criteria for surface impoundments, groundwater monitoring and protection procedures and other operational and reporting procedures to ensure the safe disposal and management of CCR. In addition to the requirements of the federal CCR regulation, CCR landfills and surface impoundments will continue to be independently regulated by most states. In accordance with ASC 410-20, Asset Retirement and Environmental Obligations - Asset Retirement Obligations, Duke Energy records an asset retirement obligation when it has a legal obligation to incur retirement costs associated with the retirement of a long-lived asset and the obligation can be reasonably estimated. 
Duke Energy Carolinas, Progress Energy, Duke Energy Progress, Duke Energy Ohio and Duke Energy Indiana recorded additional asset retirement obligation amounts in the second quarter of 2015. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of necessary and prudently incurred costs associated with Duke Energy’s regulated operations. See Note 7 for additional information.
LITIGATION
Duke Energy
Ash Basin Shareholder Derivative Litigation
Five shareholder derivative lawsuits were filed in Delaware Chancery Court relating to the release at Dan River and to the management of Duke Energy’s ash basin waterbasins. On October 31, 2014, the five lawsuits were consolidated in a single proceeding titled "In Re Duke Energy Corporation Coal Ash Derivative Litigation." On December 2, 2014, plaintiffs filed a Corrected Verified Consolidated Shareholder Derivative Complaint (Consolidated Complaint). The Consolidated Complaint names as defendants several current and former Duke Energy officers and directors (collectively, the “Duke Energy Defendants”). Duke Energy is named as a nominal defendant.
The Consolidated Complaint alleges the Duke Energy Defendants breached their fiduciary duties by failing to adequately oversee Duke Energy’s ash basins and that these breaches of fiduciary duty may have contributed to the incident at Dan River and continued thereafter. The lawsuit also asserts claims against the Duke Energy Defendants for corporate waste (relating to the money Duke Energy has spent and will spend as a result of the fines, penalties and coal ash removal) and unjust enrichment (relating to the compensation and director remuneration that was received despite these alleged breaches of fiduciary duty). The lawsuit seeks both injunctive relief against Duke Energy and restitution from the Duke Energy Defendants. On January 21, 2015, the Duke Energy Defendants filed a Motion to Stay and an alternative Motion to Dismiss.

On March 5, 2015, shareholder Judy Mesirov filed a shareholder derivative complaint (Mesirov Complaint) in North Carolina state court. The lawsuit, styled Mesirov v. Good, is similar to the consolidated derivative action pending in Delaware Chancery Court and was filed against the same current directors and former directors and officers as the Delaware litigation. Duke Energy Corporation, Duke Energy Progress and Duke Energy Carolinas are named as nominal defendants. The Mesirov Complaint alleges that the Duke Energy Board of Directors was aware of Clean Water Act (CWA) compliance issues and failures to maintain structures in ash basins, but that the Board of Directors did not require Duke Energy Carolinas and Duke Energy Progress to take action to remedy deficiencies. The Mesirov Complaint further alleges that the Board of Directors sanctioned activities to avoid compliance with the law by allowing improper influence of DENR to minimize regulation and by opposing previously anticipated citizen suit litigation. The Mesirov Complaint seeks corporate governance reforms and damages relating to costs associated with the Dan River release, discussedremediation of ash basins that are out of compliance with the CWA and defending and payment of fines, penalties and settlements relating to criminal and civil investigations and lawsuits.
In addition to the above DENR issuedderivative complaints, Duke Energy has also received two shareholder litigation demand letters. On May 28, 2014, Duke Energy received a Noticeshareholder litigation demand letter sent on behalf of Violationshareholder Mitchell Pinsly. The letter alleges that the members of the Board of Directors and Recommendationcertain officers breached their fiduciary duties by allowing the company to illegally dispose of Assessmentand store coal ash pollutants. The letter demands that the Board of Civil PenaltiesDirectors take action to recover damages associated with those breaches of fiduciary duty; otherwise, the attorney will file a shareholder derivative action. By letter dated July 3, 2014, counsel for the shareholder was informed that the Board of Directors appointed a Demand Review Committee to evaluate the allegations in the Demand Letter.
On March 24, 2015, Duke Energy received a shareholder litigation demand letter sent on behalf of shareholder Saul Bresalier. The letter alleges that the members of the Board of Directors and certain officers breached their fiduciary duties in their management of the Duke Energy's environmental practices, as well as in their decision-making relating to the leadership changes following the close of the Progress Energy merger in July 2012. The letter demands that the Board of Directors take action to recover damages associated with those alleged breaches of fiduciary duty; otherwise, the attorney will file a shareholder derivative action. In May 2015, counsel for the shareholder was informed that the matter had been referred to the Demand Review Committee.
It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with these matters.
Ash Basin Shareholder Securities Litigation
On May 26, 2015, Plaintiff E.F. Greenberg filed a lawsuit against the members of the Duke Energy Board of Directors (the Board) alleging violations of Section 14(a) of the Exchange Act for false or misleading statements contained in Duke Energy’s 2015 Proxy Statement. The plaintiff contends the Board caused Duke Energy to omit material facts from the 2015 Proxy Statement that a reasonable shareholder would consider important in casting a vote, especially with respect to this matter on February 28, 2014, which the company respondedelection of directors. Accordingly, Plaintiff alleges that shareholders were misled in casting their votes. Plaintiff seeks a determination that the 2015 Proxy Statement was false and misleading, an order from the court invalidating all votes from the Annual Meeting and requiring a revised 2015 Proxy Statement, as well as attorneys’ fees. On July 31, 2015, the defendants filed a Motion to on March 13, 2014. Dismiss the case. It is not possible to predict the outcome that might occur in connection with the remaining matters.
Progress Energy Merger Shareholder Litigation
Duke Energy, the 11 members of the Board of Directors who were also members of the pre-merger Board of Directors (Legacy Duke Energy Directors) and certain Duke Energy employees received subpoenas issued byofficers are defendants in a purported securities class action lawsuit (Nieman v. Duke Energy Corporation, et al). This lawsuit consolidates three lawsuits originally filed in July 2012, and is pending in the United States AttorneyDistrict Court for the EasternWestern District of North CarolinaCarolina. The plaintiffs allege federal Securities Act and Exchange Act claims based on allegations of materially false and misleading representations and omissions in the Registration Statement filed on July 7, 2011, and purportedly incorporated into other documents, all in connection with the post-merger change in Chief Executive Officer (CEO).
On August 15, 2014 the parties reached an agreement in principle to settle the litigation. On March 10, 2015, the parties filed a criminal investigation related to all 14Stipulation of Settlement and a Motion for Preliminary Approval of the Settlement. The court issued an order for preliminary approval of the settlement on March 25, 2015. Under the terms of the agreement, Duke Energy agreed to pay $146 million to settle the claim. On April 22, 2015, Duke Energy made a payment of $25 million into the settlement escrow account. The remainder of $121 million was paid by insurers into the settlement escrow account. Notice has been sent to members of the class and a final approval hearing is scheduled for August 12, 2015.
On May 31, 2013, the Delaware Chancery Court consolidated four shareholder derivative lawsuits filed in 2012. The Court also appointed a lead plaintiff and counsel for plaintiffs and designated the case as In Re Duke Energy Corporation Derivative Litigation. The lawsuit names as defendants the Legacy Duke Energy Directors. Duke Energy is named as a nominal defendant. The case alleges claims for breach of fiduciary duties of loyalty and care in connection with the post-merger change in CEO. The case is stayed pending resolution of the Nieman v. Duke Energy Corporation, et al. case in North Carolina.
Two shareholder Derivative Complaints, filed in 2012 in federal district court in Delaware, were consolidated as Tansey v. Rogers, et al. The case alleges claims for breach of fiduciary duty and waste of corporate assets, as well as claims under Section 14(a) and 20(a) of the Exchange Act. Duke Energy is named as a nominal defendant. Pursuant to an order entered on September 2, 2014, the court administratively closed this consolidated derivative action. The parties filed a status report with the court on December 1, 2014, and will continue to do so every six months thereafter until the Nieman v. Duke Energy Corporation, et al. case in North Carolina facilitieshas been resolved.
It is not possible to estimate the maximum exposure of loss that may occur in connection with ash basins and the nature of Duke Energy's contacts with DENR with respect to those facilities. This is a multidistrict investigation that also involves state law enforcement authorities.these lawsuits.

Lee Steam Electric Plant, Cape Fear Steam Electric Plant and Asheville Steam Electric Generating Plant. The USDOJ charged Duke Energy Carolinas and DEBS with five misdemeanor CWA violations related to violations at Duke Energy Carolinas’ Dan River Steam Station and Riverbend Steam Station. DEBS, Duke Energy Carolinas and Duke Energy Progress also agreed (i) to a five-year probation period, (ii) to pay a total of approximately $68 million in fines and restitution and $34 million for community service and mitigation (the Payments), (iii) to fund and establish environmental compliance plans subject to the oversight of a court-appointed monitor in addition to certain other conditions set out in the Plea Agreements. Duke Energy Carolinas and Duke Energy Progress also agree to each maintain $250 million under their Master Credit Facility as security to meet their obligations under the Plea Agreements. Payments under the Plea Agreements will be borne by shareholders and are not tax deductible. Duke Energy Corporation has agreed to issue a guarantee of all payments and performance due from DEBS, Duke Energy Carolinas and Duke Energy Progress, including but not limited to payments for fines, restitution, community service, mitigation and the funding of, and obligations under, the environmental compliance plans. As a result of the Plea Agreements, Duke Energy Carolinas and Duke Energy Progress have liabilities of $72 million and $30 million, respectively, within Accounts payable on the Condensed Consolidated Balance Sheets.
The Plea Agreements do not cover pending civil claims related to the Dan River coal ash release and operations at other North Carolina coal plants. Duke Energy Corporation will continue to cooperate with government agencies and defend against remaining civil litigation associated with these matters.
Duke Energy Carolinas
New Source Review
In 1999-2000, the U.S. Department of Justice (DOJ) on behalf of the EPA filed a number of complaints and notices of violation against multiple utilities, including Duke Energy Carolinas, for alleged violations of the New Source Review (NSR) provisions of the Clean Air Act (CAA). The government alleges the utilities violated the CAA when undertaking certain maintenance and repair projects at certain coal plants without (i) obtaining NSR permits and (ii) installing the best available emission controls for sulfur dioxide, nitrogen oxide and particulate matter. The complaints seek the installation of pollution control technology on generating units that allegedly violated the CAA, and unspecified civil penalties in amounts of up to $37,500 per day for each violation. Duke Energy Carolinas asserts there were no CAA violations because the applicable regulations do not require NSR permitting in cases where the projects undertaken are “routine” or otherwise do not result in a net increase in emissions.
In 2000, the government sued Duke Energy Carolinas in the U.S. District Court in Greensboro, North Carolina, claiming NSR violations for 29 projects performed at 25 of Duke Energy Carolinas’ coal-fired units. Duke Energy Carolinas asserts the projects were routine and not projected to increase emissions. The parties subsequently filed a stipulation agreeing to dismiss with prejudice all but 13 claims at 13 generating units, 11 of which have since been retired. Trial date has been set for October 2015. It is not possible to predict whether Duke Energy Carolinaswill incur any liability or to estimate the damages, if any, it might incur in connection with the remaining matters.
Brazil Expansion Lawsuit
On August 9, 2011, the State of São Paulo sued Duke Energy International Geracao Paranapenema S.A. (DEIGP) in Brazilian state court. The lawsuit claims DEIGP is under a continuing obligation to expand installed generation capacity in the State of São Paulo by 15 percent pursuant to a stock purchase agreement under which DEIGP purchased generation assets from the state. On August 10, 2011, a judge granted an ex parte injunction ordering DEIGP to present a detailed expansion plan in satisfaction of the 15 percent obligation. DEIGP has previously taken a position the expansion obligation is no longer viable given changes that have occurred in the electric energy sector since privatization. DEIGP submitted its proposed expansion plan on November 11, 2011, but reserved objections regarding enforceability. In January 2013, DEIGP filed appeals in the federal courts regarding various procedural issues. A decision on the merits in the first instance court is pending. It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with this matter. Ultimate resolution
Brazil Generation
Record drought conditions in Brazil continue to impact Duke Energy International, Geracao Paranapanema S.A. (DEIGP) in 2015. In the midst of negotiations between the hydroelectric generators and the Brazilian federal government to find ways to mitigate the financial impact on these companies, Santo Antonio Energia (SAE), a large hydro generator, filed an independent lawsuit seeking financial relief in Brazilian federal court. In May 2015, SAE was granted an injunction by a Brazilian court limiting the financial impact of its declining hydroelectric dispatch to 95 percent of its guaranteed dispatch level. Following the court’s ruling in the SAE litigation, the Brazilian electricity dispatch authority (CCEE) announced that the electric system shortfall resulting from the court-ordered limitation of liability for SAE will be compensated on a pro-rata basis with contributions from all other hydroelectric generators in Brazil. In response, the Independent Power Producer Association (APINE), on behalf of the hydroelectric generators, filed a lawsuit against the Brazilian electricity regulatory agency seeking relief from exposure to their diminished dispatch levels similar to the relief previously granted SAE. On July 2, 2015, an injunction was granted in favor of APINE limiting the market exposure of DEIGP and other independent generators to 100 percent of the guaranteed dispatch level, until the merits of the lawsuit are determined. The decision is subject to appeal. It is not possible to predict the impact to Duke Energy, if any, from the outcome of these matters could have a material effect on the results of operations, cash flows or financial position of Duke Energy Carolinas. However, the appropriate regulatory recovery will be pursued for costs incurred in connection with such resolution.
Asbestos-related Injuries and Damages Claimsmatters.
Duke Energy Carolinas has experienced numerous claims for indemnification and medical cost reimbursement related to asbestos exposure. These claims relate to damages for bodily injuries alleged to have arisen from exposure to or use of asbestos in connection with construction and maintenance activities conducted on its electric generation plants prior to 1985. As of March 31, 2015, there were 121 asserted claims for non-malignant cases with the cumulative relief sought of up to $26 million, and 32 asserted claims for malignant cases with the cumulative relief sought of up to $10 million.

DENR Notices of Violation (NOV)
In August 2014, DENR issued an NOV for alleged groundwater violations at Duke Energy FloridaProgress' L.V. Sutton Plant. On March 10, 2015, DENR issued a civil penalty of approximately $25 million to Duke Energy Progress for environmental damages related to the groundwater contamination at the L.V. Sutton Plant. On April 9, 2015, Duke Energy Progress filed a Petition for Contested Case hearing in the Office of Administrative Hearings, which has been assigned to an Administrative Judge. Duke Energy Progress has appealed the penalty on the basis that DENR exceeded its statutory authority. Hearing is scheduled for October 12, 2015.
Westinghouse Contract LitigationIn February 2015, DENR issued an NOV for alleged groundwater violations at Duke Energy Progress' Asheville Plant. Duke Energy Progress has responded to DENR regarding this NOV. DENR has not taken any enforcement action for this NOV, but penalties may be assessed in the future.
It is not possible to predict any liability or estimate any damages Duke Energy Carolinas or Duke Energy Progress might incur in connection with these matters.
North Carolina Declaratory Judgment Action
On October 10, 2012, the SELC, on behalf of the same environmental groups that were permitted to challenge the consent decrees discussed above, filed a petition with the North Carolina Environmental Management Commission (EMC) asking for a declaratory ruling seeking to clarify the application of the state’s groundwater protection rules to coal ash basins. The petition sought to change the interpretation of regulations that permitted DENR to assess the extent, cause and significance of any groundwater contamination before ordering action to eliminate the source of contamination, among other issues. Duke Energy Carolinas and Duke Energy Progress were both permitted to intervene in the matter. On December 3, 2012, the EMC affirmed this interpretation of the regulations.
On March 28,6, 2014, the North Carolina State Court judge overturned the ruling of the EMC holding that in the case of groundwater contamination, DENR was required to issue an order to immediately eliminate the source of the contamination before an assessment of the nature, significance and extent of the contamination or the continuing damage to the groundwater was conducted. Duke Energy FloridaCarolinas, Duke Energy Progress and the EMC appealed the ruling in April 2014. On May 16, 2014, the North Carolina Court of Appeals denied a petition to stay the case during the appeal. On October 10, 2014, the parties were notified the case has been transferred to the NCSC. Oral argument was held on March 16, 2015. On June 11, 2015, the North Carolina Supreme Court issued its opinion in favor of Duke Energy Carolinas, Duke Energy Progress and the EMC and remanded the matter to the state court judge with instructions to dismiss the case.
Federal Citizens Suits
There are currently five cases filed in various North Carolina federal courts contending that the DENR state enforcement actions discussed above do not adequately address the issues raised in the notices of intent to sue related to the Riverbend, Sutton, Cape Fear, H.F. Lee and Buck plants.
On June 11, 2013, Catawba Riverkeeper Foundation, Inc. (Catawba Riverkeeper) filed a lawsuit against Westinghouseseparate action in the U.S. DistrictUnited States Court for the Western District of North Carolina. The lawsuit seeks recoverycontends the state enforcement action discussed above does not adequately address issues raised in Catawba Riverkeeper’s notice of $54 million in milestone payments in excess of work performed underintent to sue relating to the terminated engineering, procurement and construction agreement (EPC) for LevyRiverbend Steam Station.

In response to a motion filed by the SELC, on August 1, 2014, the court modified the original June 9order to dismiss only the plaintiff's federal law claim based on hydrologic connections at Sutton Lake. The claims related to the alleged state court violations of the permits are back in the North Carolina case ruled that the litigation will proceedcase.
On September 3, 2014, three cases were filed by various environmental groups: (i) a citizen suit in the WesternUnited States Court for the Middle District of North Carolina. In November 2014, WestinghouseCarolina alleging unpermitted discharges to surface water and groundwater violations at the Cape Fear Plant; (ii) a citizen suit in the United States Court for the Eastern District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the H.F.

Motions to Stay or Dismiss the proceedings were filed a Motion for Partial Judgmentin each of the three cases. The proceedings related to Cape Fear and H.F. Lee have been stayed. A hearing was held August 5, 2015 on the pleadings, which was denied on March 30, 2015. Trial is set for February 2016. motion relating to Buck.
It is not possible to predict the outcome of the litigation and whether Duke Energy FloridaCarolinas or Duke Energy Progress will incur any liability for terminating the EPC or to estimate the damages, if any, itthey might incur in connection with these matters. Ultimate resolution of these matters could have a material effect on the results of operations, financial position or cash flows of Duke Energy Florida. However, appropriate regulatory recovery will be pursued for the retail portion of any costs incurred in connection with such resolution.

4. REGULATORY MATTERS
RATE RELATED INFORMATION
The NCUC, PSCSC, FPSC, IURC, PUCO and KPSC approve rates for retail electric and natural gas services within their respective states. The FERC approves rates for electric sales to wholesale customers served under cost-based rates (excluding Ohio and Indiana), as well as sales of transmission service.
Duke Energy Carolinas
William States Lee Combined Cycle Facility
On April 9, 2014, the PSCSC granted Duke Energy Carolinas and North Carolina Electric Membership Corporation (NCEMC) a Certificate of Environmental Compatibility and Public Convenience and Necessity for the construction and operation of a 750 MW combined-cycle natural gas-fired generating plant at Duke Energy Carolinas' existing William States Lee Generating Station in Anderson, South Carolina. Duke Energy Carolinas began construction in July 2015, and estimates a cost to build of $600 million for its share of the facility, including allowance for funds used during construction (AFUDC). The project is expected to be commercially available in late 2017. NCEMC will own approximately 13 percent of the project. On July 3, 2014, the South Carolina Coastal Conservation League and Southern Alliance for Clean Energy jointly filed a Notice of Appeal with the Court of Appeals of South Carolina seeking the court's review of the PSCSC's decision. The case has been fully briefed and is pending in the Court of Appeals. Duke Energy Carolinas cannot predict the outcome of this matter.
Duke Energy Progress
Sutton Black Start Combustion Turbine CPCN
On April 15, 2015, Duke Energy Progress filed a certificate of public convenience and necessity (CPCN) application with the NCUC for approval to construct an 84 MW black start combustion turbine (CT) project at the existing Sutton Plant (Sutton Black Start CT Project). The Sutton Black Start CT Project would replace three existing CTs with total capacity of 61 MW with two new 42 MW CT units with black start and fast start capability. In addition to peaking system capacity, the Sutton Black Start CT Project will provide regional black start capability and tertiary backup power services for the Brunswick Nuclear Plant. In June 2015, the Public Staff of the NCUC recommended the NCUC approve Duke Energy Progress' application. On August 3, 2015, the NCUC issued an order granting the application and requiring annual construction and cost progress reports.
Western Carolinas Modernization Plan
In May 2015, Duke Energy Progress announced a $1.1 billion plan to modernize the Western Carolinas energy system. The plan includes retiring the Asheville coal-fired plant, building a 650 MW combined-cycle natural gas power plant and installing solar generation at the site, building new transmission lines and upgrading area substations. These investments will be made within the next five years in North Carolina and South Carolina. Duke Energy is also working with the local natural gas distribution company to upgrade an existing natural gas pipeline to serve the natural gas plant. On June 24, 2015, the North Carolina governor signed into law the Mountain Energy Act of 2015 (Mountain Energy Act) which provides for an expedited CPCN process for the proposed Asheville combined-cycle project and extends certain North Carolina Coal Ash Management Act of 2014 (Coal Ash Act) deadlines for the coal ash basin at the Asheville Plant site. The plan requires various approvals including regulatory approvals in North Carolina and South Carolina.
The carrying value of the 376 MW Asheville coal-fired plant, including associated ash basin closure costs, of $460 million is included in Generation facilities to be retired, net on Duke Energy Progress' Condensed Consolidated Balance Sheet as of June 30, 2015.
Duke Energy Florida
FERC Transmission Return on Equity Complaint
Seminole Electric Cooperative, Inc. and Florida Municipal Power Agency filed multiple complaints with the FERC alleging Duke Energy Florida's current rate of return on equity in transmission formula rates of 10.8 percent is unjust and unreasonable. The latest complaint, filed on August 12, 2014, claims the rate of return on equity should be reduced to 8.69 percent. The FERC consolidated all complaints for the purposes of settlement, hearing and decision. On July 21, 2015, the parties filed with the FERC for approval of a settlement agreement under which (i) Duke Energy Florida will pay a total of $14.1 million as refunds for all periods through December 31, 2014, (ii) the rate of return on equity will be 10 percent effective January 1, 2015, and (iii) none of the parties will seek a change in the rate of return on equity prior to January 1, 2018.
Citrus County Combined Cycle Facility
On October 2, 2014, the FPSC granted Duke Energy Florida a Determination of Need for the construction of a 1,640 MW combined-cycle natural gas plant in Citrus County, Florida. On May 5, 2015, the Florida Department of Environmental Protection approved Duke Energy Florida's Site Certification Application. The facility is expected to be commercially available in 2018 at an estimated cost of $1.5 billion, including AFUDC. Additional environmental and governmental approvals will be sought for the Citrus County project.

Purchase of Osprey Energy Center
In December 2014, Duke Energy Florida and Osprey Energy Center, LLC, a wholly owned subsidiary of Calpine Corporation (Calpine), entered into an Asset Purchase and Sale Agreement for the purchase of a 599 MW combined-cycle natural gas plant in Auburndale, Florida (Osprey Plant acquisition) for approximately $166 million. On January 30, 2015, Duke Energy Florida petitioned the FPSC requesting a determination that the Osprey Plant acquisition or, alternatively, the construction of a 320 MW combustion turbine at its existing Suwannee generating facility (Suwannee project) with an estimated cost of $197 million, is the most cost-effective generation alternative to meet Duke Energy Florida's remaining generation need prior to 2018. On July 21, 2015, the FPSC approved the Osprey Plant acquisition as the most cost-effective alternative and an order is expected in August 2015. On July 24, 2015, the FERC issued an order approving the Osprey Plant acquisition. Closing of the acquisition is contingent upon the expiration of the Hart Scott Rodino waiting period and is expected to occur by the first quarter of 2017 upon the expiration of an existing Power Purchase Agreement between Calpine and Duke Energy Florida.
Crystal River Unit 3
On May 22, 2015, Duke Energy Florida petitioned the FPSC for approval to include in base rates the revenue requirement for the Crystal River Unit 3 Regulatory asset as authorized by the 2013 Revised and Restated Stipulation and Settlement Agreement (2013 Agreement). The value of the Crystal River Unit 3 Regulatory asset to be recovered is projected to be $1.298 billion at December 31, 2015. Based upon this projected value, the initial annual revenue requirement is estimated to be $170 million. 
In June 2015, the Governor of Florida signed into law legislation to allow utilities to petition for a financing order for securitization of certain retired nuclear generation assets. On July 27, 2015, Duke Energy Florida petitioned the FPSC for a financing order to finance the Crystal River Unit 3 Regulatory asset with low-cost securities. If the FPSC issues an acceptable financing order and Duke Energy Florida issues the bonds, securitization would replace the base rate recovery methodology established in the 2013 Agreement described above, and would result in a lower rate impact to customers. The annual revenue requirement with securitization, subject to changes in assumed interest rates and timing of issuance of the securitization bonds, is estimated to be approximately $100 million. The FPSC is expected to hold a hearing on both the Crystal River Unit 3 Regulatory asset filing and the securitization filing in October 2015. Duke Energy Florida cannot predict the outcome of this matter.
Levy Nuclear Project
On April 16, 2015, the FPSC approved Duke Energy Florida’s petition to cease collection of the Levy Nuclear Project fixed charge beginning with the first billing cycle in May. Duke Energy Florida also sought approval to defer collection of the $54 million regulatory asset until litigation with Westinghouse Electric Co. concludes. The FPSC found that it was unnecessary to act on the request, finding that its previous order requiring the downward adjustment in projected costs primarily affected the timing of when the fixed charge would end, but that it did not disallow recovery of any costs previously determined to be prudent.
Duke Energy Ohio
2014 Electric Security Plan
In April 2015, the PUCO modified and approved Duke Energy Ohio's proposed ESP, with a three-year term and an effective date of June 1, 2015. The PUCO approved a competitive procurement process for SSO load, a distribution capital investment rider, and a tracking mechanism for incremental distribution expenses caused by major storms. The PUCO order also approved a placeholder tariff for a price stabilization rider, but denied Duke Energy Ohio's specific request to include OVEC in the rider at this time; however, the order allows Duke Energy Ohio to submit additional information to request recovery in the future. On May 4, 2015, Duke Energy Ohio filed an application for rehearing requesting the PUCO to modify or amend certain aspects of the order. On May 14, 2015, Duke Energy Ohio completed a competitive bidding process to procure a portion of the supply for its SSO load for the term of the ESP. The PUCO approved the results on May 15, 2015. On May 28, 2015, the PUCO granted all applications for rehearing filed in the case for future consideration. Duke Energy Ohio cannot predict the outcome of this matter.
2012 Natural Gas Rate Case
On November 13, 2013, the PUCO issued an order approving a settlement among Duke Energy Ohio, the PUCO Staff and intervening parties (the Gas Settlement). The Gas Settlement provided for (i) no increase in base rates for natural gas distribution service and (ii) a return on equity of 9.84 percent. The Gas Settlement provided for a subsequent hearing on Duke Energy Ohio’s request for rider recovery of environmental remediation costs associated with its former manufactured gas plant (MGP) sites. The PUCO authorized Duke Energy Ohio to recover $56 million, excluding carrying costs, of environmental remediation costs. The MGP rider became effective in April 2014 for a five-year period. On March 31, 2014, Duke Energy Ohio filed an application with the PUCO to adjust the MGP rider for investigation and remediation costs incurred in 2013.
Certain consumer groups appealed the PUCO’s decision authorizing the MGP rider to the Ohio Supreme Court and asked the court to stay implementation of the PUCO’s order and collections under the MGP rider pending their appeal. The Ohio Supreme Court granted the motion to stay and subsequently required the posting of a bond to effectuate the stay. When the bond was not posted, the PUCO approved Duke Energy Ohio’s request, in January 2015, to reinstate collections under the MGP rider and Duke Energy Ohio resumed billings. Amounts collected prior to the suspension of the rider were immaterial. On March 31, 2015, Duke Energy Ohio filed an application to adjust the MGP rider to recover remediation costs incurred in 2014. Duke Energy Ohio cannot predict the outcome of the appeal of this matter.
Regional Transmission Organization (RTO) Realignment
Duke Energy Ohio, including Duke Energy Kentucky, transferred control of its transmission assets from Midcontinent Independent System Operator, Inc. (MISO) to PJM Interconnection, LLC (PJM), effective December 31, 2011.

On December 22, 2010, the KPSC approved Duke Energy Kentucky’s request to effect the RTO realignment, subject to a commitment not to seek double recovery in a future rate case of the transmission expansion fees that may be charged by MISO and PJM in the same period or overlapping periods.
On May 25, 2011, the PUCO approved a settlement between Duke Energy Ohio, Ohio Energy Group, the Office of Ohio Consumers’ Counsel and the PUCO Staff related to Duke Energy Ohio’s recovery of certain costs of the RTO realignment via a non-bypassable rider. Duke Energy Ohio is allowed to recover all MISO Transmission Expansion Planning (MTEP) costs, including but not limited to Multi Value Project (MVP) costs, directly or indirectly charged to Ohio customers. Duke Energy Ohio also agreed to vigorously defend against any charges for MVP projects from MISO.
Upon its exit from MISO on December 31, 2011, Duke Energy Ohio recorded a liability for its exit obligation and share of MTEP costs, excluding MVP. This liability was recorded within Other in Current liabilities and Other in Deferred credits and other liabilities on Duke Energy Ohio’s Condensed Consolidated Balance Sheets.
As of June 30, 2015, Duke Energy Ohio had recorded obligations of $93 million related to its withdrawal from MISO and a Regulatory asset of $73 million recorded on the Condensed Consolidated Balance Sheets. MTEP costs billed by MISO are recovered by Duke Energy Ohio through a non-bypassable rider.
MVP. MISO approved 17 MVP proposals prior to Duke Energy Ohio’s exit from MISO on December 31, 2011. Construction of these projects is expected to continue through 2020. Costs of these projects, including operating and maintenance costs, property and income taxes, depreciation and an allowed return, are allocated and billed to MISO transmission owners.
On December 29, 2011, MISO filed a tariff with the FERC providing for the allocation of MVP costs to a withdrawing owner based on monthly energy usage. The FERC set for hearing (i) whether MISO’s proposed cost allocation methodology to transmission owners who withdrew from MISO prior to January 1, 2012 is consistent with the tariff at the time of their withdrawal from MISO, and, (ii) if not, what the amount of and methodology for calculating any MVP cost responsibility should be. On July 16, 2013, a FERC Administrative Law Judge (ALJ) issued an initial decision. Under this initial decision, Duke Energy Ohio would be liable for MVP costs. Duke Energy Ohio filed exceptions to the initial decision, requesting the FERC overturn the ALJ’s decision. After reviewing the initial decision, along with all exceptions and responses filed by the parties, the FERC will issue a final decision. Duke Energy Ohio fully intends to appeal to the federal court of appeals if the FERC affirms the ALJ’s decision. Duke Energy Ohio cannot predict the outcome of these proceedings.
In 2012, MISO estimated Duke Energy Ohio’s MVP obligation over the period from 2012 to 2071 at $2.7 billion, on an undiscounted basis. The estimated obligation is subject to great uncertainty including the ultimate cost of the projects, the annual costs of operations and maintenance, taxes and return over the project lives, the number of years in service for the projects and the allocation to Duke Energy Ohio.
Any liability related to the MISO MVP matter or MTEP costs attributable to the Disposal Group was not transferred to Dynegy upon the sale of the nonregulated Midwest generation business.
FERC Transmission Return on Equity and MTEP Cost Settlement
On October 14, 2011, Duke Energy Ohio and Duke Energy Kentucky submitted with the FERC proposed modifications to the PJM Interconnection Open Access Transmission Tariff pertaining to recovery of the transmission revenue requirement as PJM transmission owners. The filing was made in connection with Duke Energy Ohio's and Duke Energy Kentucky's move from MISO to PJM effective January 1, 2012. On April 24, 2012, the FERC issued an order accepting the proposed filing effective January 1, 2012, except that the order denied a request to recover certain costs associated with the move from MISO to PJM without prejudice to the right to submit another filing seeking such recovery and including certain additional evidence, and set the rate of return on equity of 12.38 percent for settlement and hearing. On April 16, 2015, the FERC approved a settlement agreement between Duke Energy Ohio, Duke Energy Kentucky and six PJM transmission customers with load in the Duke Energy Ohio and Duke Energy Kentucky zone. The principal terms of the settlement agreement are that, effective upon the date of FERC approval, (i) the return on equity for wholesale transmission service is reduced to 11.38 percent, (ii) the settling parties agreed not to seek a change in the return on equity that would be effective prior to June 1, 2017, and (iii) Duke Energy Ohio and Duke Energy Kentucky will recover 30 percent of the wholesale portion of costs arising from their obligation to pay any portion of the costs of projects included in any MTEP that was approved prior to the date of Duke Energy Ohio's and Duke Energy Kentucky's integration into PJM.
Duke Energy Indiana
Edwardsport Integrated Gasification Combined Cycle (IGCC) Plant
On November 20, 2007, the IURC granted Duke Energy Indiana a CPCN for the construction of the Edwardsport IGCC Plant. The Citizens Action Coalition of Indiana, Inc., Sierra Club, Inc., Save the Valley, Inc., and Valley Watch, Inc. (collectively, the Joint Intervenors) were intervenors in several matters related to the Edwardsport IGCC Plant. The Edwardsport IGCC Plant was placed in commercial operation in June 2013. Costs for the Edwardsport IGCC Plant are recovered from retail electric customers via a tracking mechanism, the IGCC rider. Updates to the IGCC rider are filed semi-annually.
The ninth semi-annual IGCC rider order was appealed by the Joint Intervenors. On September 8, 2014, the Indiana Court of Appeals remanded the IURC order in the ninth IGCC rider proceeding back to the IURC for further findings. On February 25, 2015, the IURC issued a new order upholding its prior decision and provided additional detailed findings. Joint Intervenors have appealed this remand order to the Indiana Court of Appeals.
The 10th semi-annual IGCC rider order was also appealed by the Joint Intervenors. On August 21, 2014 the Indiana Court of Appeals affirmed the IURC order in the 10th IGCC rider proceeding and on October 29, 2014 denied the Joint Intervenors' request for rehearing. The Joint Intervenors requested the Indiana Supreme Court to review the decision, which was denied on April 23, 2015, concluding the appeal.

An order on the 11th semi-annual IGCC rider is currently pending. The 12th and 13th semi-annual IGCC riders were combined for hearings which were held in February 2015 and an order is currently pending. Issues in this proceeding include whether the IGCC plant was properly declared in service for ratemaking purposes in June 2013 and the operational performance of the plant during its initial 10 months of operations. Duke Energy Indiana has filed the 14th and 15th semi-annual IGCC rider proceedings, with a hearing scheduled in November 2015.
On April 2, 2014, the IURC established a subdocket to Duke Energy Indiana’s current fuel adjustment clause proceeding. In this fuel adjustment subdocket, the IURC intends to review underlying causes for net negative generation amounts at the Edwardsport IGCC Plant during the period September through November 2013. Duke Energy Indiana contends the net negative generation is related to the consumption of fuel and auxiliary power when the plant was in start-up or off line. In addition to the OUCC, the Duke Energy Indiana Industrial Group, Nucor Steel-Indiana, Steel Dynamics, Inc., and the Joint Intervenors are parties to the subdocket. The IURC has deferred the fuel adjustment subdocket until resolution of the 12th and 13th semi-annual IGCC rider proceedings. In addition, although the IURC approved fuel adjustment clause recovery for the period December 2013 through March 2014, it determined such fuel costs reasonably related to the operational performance of the Edwardsport IGCC Plant shall be subject to refund pending the outcome of the 12th and 13th semi-annual IGCC riders.
On August 6, 2015, the IURC granted a motion to defer ruling on all pending matters until September 15, 2015 to allow time for settlement discussions. The Commission is expected to proceed with issuance of an order if the parties do not reach a settlement agreement. Duke Energy Indiana cannot predict the outcome of the fuel adjustment clause proceedings or pending and future IGCC rider proceedings.
FERC Transmission Return on Equity Complaint
Customer groups have filed with the FERC complaints against MISO and its transmission-owning members, including Duke Energy Indiana, alleging, among other things, that the current base rate of return on equity earned by MISO transmission owners of 12.38 percent is unjust and unreasonable. The latest complaint, filed on February 12, 2015, claims the base rate of return on equity should be reduced to 8.67 percent and requests a consolidation of complaints. On January 5, 2015, the FERC issued an order accepting the MISO transmission owners 0.50 percent adder to the base rate of return on equity based on participation in an RTO subject to it being applied to a return on equity that is shown to be just and reasonable in the pending return on equity complaint. Settlement procedures in the base return on equity proceeding were terminated and a hearing is scheduled for August 17, 2015. Duke Energy Indiana cannot predict the outcome of this matter.
Grid Infrastructure Improvement Plan
On August 29, 2014, Duke Energy Indiana filed a seven-year grid infrastructure improvement plan with the IURC with an estimated cost of $1.9 billion, focusing on the reliability, integrity and modernization of the transmission and distribution system. In May 2015, the IURC denied the proposal due to an insufficient level of detailed projects and cost estimates in the plan. Duke Energy Indiana is evaluating the order and plans to file a revised infrastructure improvement plan by the end of 2015.
OTHER REGULATORY MATTERS
Atlantic Coast Pipeline
On September 2, 2014, Duke Energy, Dominion Resources (Dominion), Piedmont Natural Gas and AGL Resources announced the formation of a company, Atlantic Coast Pipeline, LLC (ACP), to build and own the proposed Atlantic Coast Pipeline (the pipeline), a 550-mile interstate natural gas pipeline. The pipeline is designed to meet the needs identified in requests for proposals by Duke Energy Carolinas, Duke Energy Progress and Piedmont Natural Gas. Dominion will build and operate the pipeline and will own 45 percent. Duke Energy will have a 40 percent ownership interest in ACP through its Commercial Portfolio segment. The remaining share will be owned by Piedmont Natural Gas and AGL Resources. Duke Energy Carolinas and Duke Energy Progress, among others, will be customers of the pipeline. Purchases will be made under several 20-year supply contracts, subject to state regulatory approval. In October 2014, the NCUC and PSCSC approved the Duke Energy Carolinas and Duke Energy Progress requests to enter into certain affiliate agreements, pay compensation to ACP and to grant a waiver of certain Code of Conduct provisions relating to contractual and jurisdictional matters. The project will require FERC approval, which ACP will seek to secure by summer 2016. The estimated in-service date of the pipeline is late 2018.
Sabal Trail Transmission, LLC Pipeline
On May 4, 2015, Duke Energy acquired a 7.5 percent ownership interest from Spectra Energy in the proposed 500-mile Sabal Trail natural gas pipeline. Spectra Energy will continue to own 59.5 percent of the pipeline and NextEra Energy will own the remaining 33 percent of the pipeline. The pipeline will traverse Alabama, Georgia and Florida to meet rapidly growing demand for natural gas in those states. The primary customers of the pipeline, Duke Energy Florida and Florida Power & Light Company, have each contracted to buy pipeline capacity for 25-year initial terms. The pipeline, scheduled to begin service in 2017, requires federal and other regulatory approvals. 
East Bend Station
On December 30, 2014, Duke Energy Ohio acquired The Dayton Power and Light Company's (DP&L) 31 percent interest in East Bend Station for approximately $12.4 million. The purchase price, in accordance with FERC guidelines, was reflected with the net purchase amount as an increase to property, plant and equipment as of December 31, 2014 and with the DP&L's historical original cost as an increase to property, plant and equipment and accumulated depreciation as of June 30, 2015.

NC WARN FERC Complaint
On December 16, 2014, North Carolina Waste Awareness and Reduction Network filed a complaint with the FERC against Duke Energy Carolinas and Duke Energy Progress that alleged (i) Duke Energy Carolinas and Duke Energy Progress manipulated the electricity market by constructing costly and unneeded generation facilities leading to unjust and unreasonable rates; (ii) Duke Energy Carolinas and Duke Energy Progress failed to comply with Order 1000 by not effectively connecting their transmission systems with neighboring utilities which also have excess capacity; (iii) the plans of Duke Energy Carolinas and Duke Energy Progress for unrealistic future growth lead to unnecessary and expensive generating plants; (iv) the FERC should investigate the practices of Duke Energy Carolinas and Duke Energy Progress and the potential benefits of having them enter into a regional transmission organization; and (v) the FERC should force Duke Energy Carolinas and Duke Energy Progress to purchase power from other utilities rather than construct wasteful and redundant power plants. NC WARN also filed a copy of the complaint with the PSCSC on January 6, 2015. In April 2015, the FERC and the PSCSC issued separate orders dismissing the NC WARN petition. On May 14, 2015, NC WARN filed with FERC a motion for reconsideration.
Potential Coal Plant Retirements
The Subsidiary Registrants periodically file Integrated Resource Plans (IRP) with their state regulatory commissions. The IRPs provide a view of forecasted energy needs over a long term (10 to 20 years), and options being considered to meet those needs. Recent IRPs filed by the Subsidiary Registrants included planning assumptions to potentially retire certain coal-fired generating facilities in North Carolina, Florida and Indiana earlier than their current estimated useful lives. These facilities do not have the requisite emission control equipment, primarily to meet United States Environmental Protection Agency (EPA) regulations recently approved or proposed.
The table below contains the net carrying value of generating facilities planned for retirement or included in recent IRPs as evaluated for potential retirement due to a lack of requisite environmental control equipment. Dollar amounts in the table below are included in Net property, plant and equipment on the Condensed Consolidated Balance Sheets.

Duke Energy Indiana committed to retire or convert the Wabash River Units 2 through 5 by June 2018 in conjunction with a settlement agreement associated with the Edwardsport air permit.
In addition to evaluations based on the extent facilities are equipped to comply with environmental regulations, Duke Energy continually monitors and evaluates the appropriate generation mix and fuel diversity for its generation fleet when making retirement decisions. Duke Energy Carolinas is evaluating the potential retirement of coal-fired generating units with a net carrying value of approximately $110 million, excluding capitalized asset retirement costs related to closure of ash basins, included in Net property, plant and equipment on the Condensed Consolidated Balance Sheets. These generating units are not included in the table above.
Duke Energy continues to evaluate the potential need to retire generating facilities earlier than the current estimated useful lives, and plans to seek regulatory recovery, as necessary, for amounts that would not be otherwise recovered when any of these assets are retired. However, such recovery, including recovery of carrying costs on remaining book values, could be subject to future regulatory approvals and therefore cannot be assured.
Refer to the "Western Carolinas Modernization Plan" discussion above for details of planned retirements for Duke Energy Progress.

Remediation Activities
The Duke Energy Registrants are responsible for environmental remediation at various contaminated sites. These include some properties that are part of ongoing operations and sites formerly owned or used by Duke Energy entities. These sites are in various stages of investigation, remediation and monitoring. Managed in conjunction with relevant federal, state and local agencies, activities vary with site conditions and locations, remediation requirements, complexity and sharing of responsibility. If remediation activities involve joint and several liability provisions, strict liability, or cost recovery or contribution actions, the Duke Energy Registrants could potentially be held responsible for contamination caused by other potentially responsible parties, and may also benefit from insurance policies or contractual indemnities that cover some or all cleanup costs. Liabilities are recorded when losses become probable and are reasonably estimable. The total costs that may be incurred cannot be estimated because the extent of environmental impact, allocation among potentially responsible parties, remediation alternatives and/or regulatory decisions have not yet been determined. Additional costs associated with remediation activities are likely to be incurred in the future and could be significant. Costs are typically expensed as Operation, maintenance and other in the Condensed Consolidated Statements of Operations unless regulatory recovery of the costs is deemed probable.
The following tables contain information regarding reserves for probable and estimable costs related to the various environmental sites. These reserves are recorded in Other within Deferred Credits and Other Liabilities on the Condensed Consolidated Balance Sheets.

North Carolina and South Carolina Ash Basins
On February 2, 2014, a break in a stormwater pipe beneath an ash basin at Duke Energy Carolinas’ retired Dan River Steam Station caused a release of ash basin water and ash into the Dan River. On February 8, 2014, a permanent plug was installed in the stormwater pipe, stopping the release of materials into the river. Duke Energy Carolinas estimates 30,000 to 39,000 tons of ash and 24 million to 27 million gallons of basin water were released into the river. In July 2014, Duke Energy completed remediation work identified by the EPA and continues to cooperate with the EPA's civil enforcement process. Total repairs and remediation expenses incurred by Duke Energy Carolinas related to the release were approximately $24 million. No additional expenses were recorded in 2015. Duke Energy Carolinas will not seek recovery of these costs from ratepayers. See the "Litigation" section below for additional information on litigation, investigations and enforcement actions related to ash basins, including the Memorandum of Plea Agreement (Plea Agreements) in connection to the North Carolina Ash Basin Grand Jury Investigation. Other costs related to the Dan River release, including pending or future state or federal civil enforcement proceedings, future regulatory directives, natural resources damages, additional pending litigation, future claims or litigation, and long-term environmental impact costs cannot be reasonably estimated at this time.

On September 20, 2014, the Coal Ash Act became law and was amended on June 24, 2015, by the Mountain Energy Act. The Coal Ash Act, as amended, (i) establishes a Coal Ash Management Commission (Coal Ash Commission) to oversee handling of coal ash within the state; (ii) prohibits construction of new and expansion of existing ash impoundments and use of existing impoundments at retired facilities; (iii) requires closure of ash impoundments at Duke Energy Progress' Sutton Plant and Duke Energy Carolinas' Riverbend and Dan River stations no later than August 1, 2019 and Duke Energy Progress' Asheville Plant no later than August 1, 2022; (iv) requires dry disposal of fly ash at active plants, excluding the Asheville Plant, not retired by December 31, 2018; (v) requires dry disposal of bottom ash at active plants, excluding the Asheville Plant, by December 31, 2019, or retirement of active plants; (vi) requires all remaining ash impoundments in North Carolina to be categorized as high-risk, intermediate-risk or low-risk no later than December 31, 2015 by the North Carolina Department of Environment and Natural Resources (DENR) with the method of closure and timing to be based upon the assigned risk, with closure no later than December 31, 2029; (vii) establishes requirements to deal with groundwater and surface water impacts from impoundments; and (viii) enhances the level of regulation for structural fills utilizing coal ash. The Coal Ash Act includes a variance procedure for compliance deadlines and modification of requirements regarding structural fills and compliance boundaries. Provisions of the Coal Ash Act prohibit cost recovery in customer rates for unlawful discharge of ash basin waters occurring after January 1, 2014. The Coal Ash Act leaves the decision on cost recovery determinations related to closure of coal combustion residual (CCR) surface impoundments (ash basins or impoundments) to the normal ratemaking processes before utility regulatory commissions. Duke Energy has and will periodically submit to DENR site-specific coal ash impoundment closure plans or excavation plans in advance of closure plans. These plans and all associated permits must be approved by DENR before any excavation or closure work can begin.
In September 2014, Duke Energy Carolinas executed a consent agreement with the South Carolina Department of Health and Environmental Control (SCDHEC) requiring the excavation of an inactive ash basin and ash fill area at the W.S. Lee Steam Station. As part of this agreement, in December 2014, Duke Energy Carolinas filed an ash removal plan and schedule with SCDHEC. In April 2015, the federal CCR rules were published and Duke Energy Carolinas subsequently executed an agreement with the conservation groups Upstate Forever and Save Our Saluda requiring Duke Energy Carolinas to remediate all active and inactive ash storage areas at the W.S. Lee Steam Station. Coal-fired generation at W.S. Lee ceased in 2014 and unit 3 is being converted to natural gas. In July 2015, Duke Energy Progress executed a consent agreement with the SCDHEC requiring the excavation of an inactive ash fill area at the Robinson Plant within eight years. The Robinson Plant and W.S. Lee Station sites are required to be closed pursuant to the recently issued CCR rule and the provisions of these consent agreements are consistent with the federal CCR closure requirements.
Asset retirement obligations are recorded on the Duke Energy Carolinas and Duke Energy Progress Condensed Consolidated Balance Sheets at June 30, 2015 based upon the legal obligation for closure of coal ash basins and the disposal of related ash as a result of the Coal Ash Act and the agreement with SCDHEC. See Note 7 for additional information.
Coal Combustion Residuals
On April 17, 2015, the EPA published in the Federal Register a rule to regulate the disposal of CCR from electric utilities as solid waste. The federal regulation classifies CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act and allows beneficial use of CCRs with some restrictions. The regulation applies to all new and existing landfills, new and existing surface impoundments, structural fills and CCR piles. The rule establishes requirements regarding landfill design, structural integrity design and assessment criteria for surface impoundments, groundwater monitoring and protection procedures and other operational and reporting procedures to ensure the safe disposal and management of CCR. In addition to the requirements of the federal CCR regulation, CCR landfills and surface impoundments will continue to be independently regulated by most states. In accordance with ASC 410-20, Asset Retirement and Environmental Obligations - Asset Retirement Obligations, Duke Energy records an asset retirement obligation when it has a legal obligation to incur retirement costs associated with the retirement of a long-lived asset and the obligation can be reasonably estimated. 
Duke Energy Carolinas, Progress Energy, Duke Energy Progress, Duke Energy Ohio and Duke Energy Indiana recorded additional asset retirement obligation amounts in the second quarter of 2015. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of necessary and prudently incurred costs associated with Duke Energy’s regulated operations. See Note 7 for additional information.
LITIGATION
Duke Energy
Ash Basin Shareholder Derivative Litigation
Five shareholder derivative lawsuits were filed in Delaware Chancery Court relating to the release at Dan River and to the management of Duke Energy’s ash basins. On October 31, 2014, the five lawsuits were consolidated in a single proceeding titled "In Re Duke Energy Corporation Coal Ash Derivative Litigation." On December 2, 2014, plaintiffs filed a Corrected Verified Consolidated Shareholder Derivative Complaint (Consolidated Complaint). The Consolidated Complaint names as defendants several current and former Duke Energy officers and directors (collectively, the “Duke Energy Defendants”). Duke Energy is named as a nominal defendant.
The Consolidated Complaint alleges the Duke Energy Defendants breached their fiduciary duties by failing to adequately oversee Duke Energy’s ash basins and that these breaches of fiduciary duty may have contributed to the incident at Dan River and continued thereafter. The lawsuit also asserts claims against the Duke Energy Defendants for corporate waste (relating to the money Duke Energy has spent and will spend as a result of the fines, penalties and coal ash removal) and unjust enrichment (relating to the compensation and director remuneration that was received despite these alleged breaches of fiduciary duty). The lawsuit seeks both injunctive relief against Duke Energy and restitution from the Duke Energy Defendants. On January 21, 2015, the Duke Energy Defendants filed a Motion to Stay and an alternative Motion to Dismiss.

On March 5, 2015, shareholder Judy Mesirov filed a shareholder derivative complaint (Mesirov Complaint) in North Carolina state court. The lawsuit, styled Mesirov v. Good, is similar to the consolidated derivative action pending in Delaware Chancery Court and was filed against the same current directors and former directors and officers as the Delaware litigation. Duke Energy Corporation, Duke Energy Progress and Duke Energy Carolinas are named as nominal defendants. The Mesirov Complaint alleges that the Duke Energy Board of Directors was aware of Clean Water Act (CWA) compliance issues and failures to maintain structures in ash basins, but that the Board of Directors did not require Duke Energy Carolinas and Duke Energy Progress to take action to remedy deficiencies. The Mesirov Complaint further alleges that the Board of Directors sanctioned activities to avoid compliance with the law by allowing improper influence of DENR to minimize regulation and by opposing previously anticipated citizen suit litigation. The Mesirov Complaint seeks corporate governance reforms and damages relating to costs associated with the Dan River release, remediation of ash basins that are out of compliance with the CWA and defending and payment of fines, penalties and settlements relating to criminal and civil investigations and lawsuits.
In addition to the above derivative complaints, Duke Energy has also received two shareholder litigation demand letters. On May 28, 2014, Duke Energy received a shareholder litigation demand letter sent on behalf of shareholder Mitchell Pinsly. The letter alleges that the members of the Board of Directors and certain officers breached their fiduciary duties by allowing the company to illegally dispose of and store coal ash pollutants. The letter demands that the Board of Directors take action to recover damages associated with those breaches of fiduciary duty; otherwise, the attorney will file a shareholder derivative action. By letter dated July 3, 2014, counsel for the shareholder was informed that the Board of Directors appointed a Demand Review Committee to evaluate the allegations in the Demand Letter.
On March 24, 2015, Duke Energy received a shareholder litigation demand letter sent on behalf of shareholder Saul Bresalier. The letter alleges that the members of the Board of Directors and certain officers breached their fiduciary duties in their management of the Duke Energy's environmental practices, as well as in their decision-making relating to the leadership changes following the close of the Progress Energy merger in July 2012. The letter demands that the Board of Directors take action to recover damages associated with those alleged breaches of fiduciary duty; otherwise, the attorney will file a shareholder derivative action. In May 2015, counsel for the shareholder was informed that the matter had been referred to the Demand Review Committee.
It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with these matters.
Ash Basin Shareholder Securities Litigation
On May 26, 2015, Plaintiff E.F. Greenberg filed a lawsuit against the members of the Duke Energy Board of Directors (the Board) alleging violations of Section 14(a) of the Exchange Act for false or misleading statements contained in Duke Energy’s 2015 Proxy Statement. The plaintiff contends the Board caused Duke Energy to omit material facts from the 2015 Proxy Statement that a reasonable shareholder would consider important in casting a vote, especially with respect to the election of directors. Accordingly, Plaintiff alleges that shareholders were misled in casting their votes. Plaintiff seeks a determination that the 2015 Proxy Statement was false and misleading, an order from the court invalidating all votes from the Annual Meeting and requiring a revised 2015 Proxy Statement, as well as attorneys’ fees. On July 31, 2015, the defendants filed a Motion to Dismiss the case. It is not possible to predict the outcome that might occur in connection with the remaining matters.
Progress Energy Merger Shareholder Litigation
Duke Energy, the 11 members of the Board of Directors who were also members of the pre-merger Board of Directors (Legacy Duke Energy Directors) and certain Duke Energy officers are defendants in a purported securities class action lawsuit (Nieman v. Duke Energy Corporation, et al). This lawsuit consolidates three lawsuits originally filed in July 2012, and is pending in the United States District Court for the Western District of North Carolina. The plaintiffs allege federal Securities Act and Exchange Act claims based on allegations of materially false and misleading representations and omissions in the Registration Statement filed on July 7, 2011, and purportedly incorporated into other documents, all in connection with the post-merger change in Chief Executive Officer (CEO).
On August 15, 2014 the parties reached an agreement in principle to settle the litigation. On March 10, 2015, the parties filed a Stipulation of Settlement and a Motion for Preliminary Approval of the Settlement. The court issued an order for preliminary approval of the settlement on March 25, 2015. Under the terms of the agreement, Duke Energy agreed to pay $146 million to settle the claim. On April 22, 2015, Duke Energy made a payment of $25 million into the settlement escrow account. The remainder of $121 million was paid by insurers into the settlement escrow account. Notice has been sent to members of the class and a final approval hearing is scheduled for August 12, 2015.
On May 31, 2013, the Delaware Chancery Court consolidated four shareholder derivative lawsuits filed in 2012. The Court also appointed a lead plaintiff and counsel for plaintiffs and designated the case as In Re Duke Energy Corporation Derivative Litigation. The lawsuit names as defendants the Legacy Duke Energy Directors. Duke Energy is named as a nominal defendant. The case alleges claims for breach of fiduciary duties of loyalty and care in connection with the post-merger change in CEO. The case is stayed pending resolution of the Nieman v. Duke Energy Corporation, et al. case in North Carolina.
Two shareholder Derivative Complaints, filed in 2012 in federal district court in Delaware, were consolidated as Tansey v. Rogers, et al. The case alleges claims for breach of fiduciary duty and waste of corporate assets, as well as claims under Section 14(a) and 20(a) of the Exchange Act. Duke Energy is named as a nominal defendant. Pursuant to an order entered on September 2, 2014, the court administratively closed this consolidated derivative action. The parties filed a status report with the court on December 1, 2014, and will continue to do so every six months thereafter until the Nieman v. Duke Energy Corporation, et al. case in North Carolina has been resolved.
It is not possible to estimate the maximum exposure of loss that may occur in connection with these lawsuits.

Price Reporting Cases
Five lawsuits were filed against a Duke Energy affiliate, Duke Energy Trading and Marketing, LLC, and other energy companies and remain pending in a consolidated, single federal court proceeding in Nevada. Each of these lawsuits contain similar claims that defendants allegedly manipulated natural gas markets by various means, including providing false information to natural gas trade publications and entering into unlawful arrangements and agreements in violation of the antitrust laws of the respective states. Plaintiffs seek damages in unspecified amounts.
On July 18, 2011, the judge granted a defendant’s motion for summary judgment in two of five cases. The U.S. Court of Appeals for the Ninth Circuit subsequently reversed the lower court’s decision. On April 21, 2015, the Supreme Court affirmed the U.S. Court of Appeals decision. The case has been reassigned to the same consolidated federal court proceeding in Nevada for further proceedings.
It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with the remaining matters.
Brazil Expansion Lawsuit
On August 9, 2011, the State of São Paulo sued Duke Energy International Geracao Paranapenema S.A. (DEIGP) in Brazilian state court. The lawsuit claims DEIGP is under a continuing obligation to expand installed generation capacity in the State of São Paulo by 15 percent pursuant to a stock purchase agreement under which DEIGP purchased generation assets from the state. On August 10, 2011, a judge granted an ex parte injunction ordering DEIGP to present a detailed expansion plan in satisfaction of the 15 percent obligation. DEIGP has previously taken a position the expansion obligation is no longer viable given changes that have occurred in the electric energy sector since privatization. DEIGP submitted its proposed expansion plan on November 11, 2011, but reserved objections regarding enforceability. In January 2013, DEIGP filed appeals in the federal courts regarding various procedural issues. A decision on the merits in the first instance court is pending. It is not possible to predict whether Duke Energy will incur any liability or to estimate the damages, if any, it might incur in connection with this matter.
Brazil Generation
Record drought conditions in Brazil continue to impact Duke Energy International, Geracao Paranapanema S.A. (DEIGP) in 2015. In the midst of negotiations between the hydroelectric generators and the Brazilian federal government to find ways to mitigate the financial impact on these companies, Santo Antonio Energia (SAE), a large hydro generator, filed an independent lawsuit seeking financial relief in Brazilian federal court. In May 2015, SAE was granted an injunction by a Brazilian court limiting the financial impact of its declining hydroelectric dispatch to 95 percent of its guaranteed dispatch level. Following the court’s ruling in the SAE litigation, the Brazilian electricity dispatch authority (CCEE) announced that the electric system shortfall resulting from the court-ordered limitation of liability for SAE will be compensated on a pro-rata basis with contributions from all other hydroelectric generators in Brazil. In response, the Independent Power Producer Association (APINE), on behalf of the hydroelectric generators, filed a lawsuit against the Brazilian electricity regulatory agency seeking relief from exposure to their diminished dispatch levels similar to the relief previously granted SAE. On July 2, 2015, an injunction was granted in favor of APINE limiting the market exposure of DEIGP and other independent generators to 100 percent of the guaranteed dispatch level, until the merits of the lawsuit are determined. The decision is subject to appeal. It is not possible to predict the impact to Duke Energy, if any, from the outcome of these matters.
Duke Energy Carolinas and Duke Energy Progress
DENR State Enforcement Actions
In the first quarter of 2013, environmental organizations sent notices of intent to sue Duke Energy Carolinas and Duke Energy Progress related to alleged groundwater violations and CWA violations from coal ash basins at two of their coal-fired power plants in North Carolina. DENR filed enforcement actions against Duke Energy Carolinas and Duke Energy Progress alleging violations of water discharge permits and North Carolina groundwater standards. The case against Duke Energy Carolinas was filed in Mecklenburg County Superior Court. The case against Duke Energy Progress was filed in Wake County Superior Court. The cases are being heard before a single judge.
On October 4, 2013, Duke Energy Carolinas, Duke Energy Progress and DENR negotiated a proposed consent order covering these two plants. The consent order would have assessed civil penalties and imposed a compliance schedule requiring Duke Energy Carolinas and Duke Energy Progress to undertake monitoring and data collection activities toward making appropriate corrective action to address any substantiated violations. In light of the coal ash release that occurred at Dan River on February 2, 2014, on March 21, 2014, DENR withdrew its support of the consent orders and requested that the court proceed with the litigation.
On August 16, 2013, DENR filed an enforcement action against Duke Energy Carolinas and Duke Energy Progress related to their remaining plants in North Carolina, alleging violations of the CWA and violations of the North Carolina groundwater standards. The case against Duke Energy Carolinas was filed in Mecklenburg County Superior Court. The case against Duke Energy Progress was filed in Wake County Superior Court. Both of these cases have been assigned to the judge handling the enforcement actions discussed above. The SELC, on behalf of several environmental groups, has been permitted to intervene in these cases.
On July 10, 2015, Duke Energy Carolinas and Duke Energy Progress filed Motions for Partial Summary Judgment in the case on the basis that there is no longer either a genuine controversy or disputed material facts about the relief for seven of the 14 North Carolina plants with coal ash basins.
It is not possible to predict any liability or estimate any damages Duke Energy Carolinas or Duke Energy Progress might incur in connection with these matters.

DENR Notices of Violation (NOV)
In August 2014, DENR issued an NOV for alleged groundwater violations at Duke Energy Progress' L.V. Sutton Plant. On March 10, 2015, DENR issued a civil penalty of approximately $25 million to Duke Energy Progress for environmental damages related to the groundwater contamination at the L.V. Sutton Plant. On April 9, 2015, Duke Energy Progress filed a Petition for Contested Case hearing in the Office of Administrative Hearings, which has been assigned to an Administrative Judge. Duke Energy Progress has appealed the penalty on the basis that DENR exceeded its statutory authority. Hearing is scheduled for October 12, 2015.
In February 2015, DENR issued an NOV for alleged groundwater violations at Duke Energy Progress' Asheville Plant. Duke Energy Progress has responded to DENR regarding this NOV. DENR has not taken any enforcement action for this NOV, but penalties may be assessed in the future.
It is not possible to predict any liability or estimate any damages Duke Energy Carolinas or Duke Energy Progress might incur in connection with these matters.
North Carolina Declaratory Judgment Action
On October 10, 2012, the SELC, on behalf of the same environmental groups that were permitted to challenge the consent decrees discussed above, filed a petition with the North Carolina Environmental Management Commission (EMC) asking for a declaratory ruling seeking to clarify the application of the state’s groundwater protection rules to coal ash basins. The petition sought to change the interpretation of regulations that permitted DENR to assess the extent, cause and significance of any groundwater contamination before ordering action to eliminate the source of contamination, among other issues. Duke Energy Carolinas and Duke Energy Progress were both permitted to intervene in the matter. On December 3, 2012, the EMC affirmed this interpretation of the regulations.
On March 6, 2014, the North Carolina State Court judge overturned the ruling of the EMC holding that in the case of groundwater contamination, DENR was required to issue an order to immediately eliminate the source of the contamination before an assessment of the nature, significance and extent of the contamination or the continuing damage to the groundwater was conducted. Duke Energy Carolinas, Duke Energy Progress and the EMC appealed the ruling in April 2014. On May 16, 2014, the North Carolina Court of Appeals denied a petition to stay the case during the appeal. On October 10, 2014, the parties were notified the case has been transferred to the NCSC. Oral argument was held on March 16, 2015. On June 11, 2015, the North Carolina Supreme Court issued its opinion in favor of Duke Energy Carolinas, Duke Energy Progress and the EMC and remanded the matter to the state court judge with instructions to dismiss the case.
Federal Citizens Suits
There are currently five cases filed in various North Carolina federal courts contending that the DENR state enforcement actions discussed above do not adequately address the issues raised in the notices of intent to sue related to the Riverbend, Sutton, Cape Fear, H.F. Lee and Buck plants.
On June 11, 2013, Catawba Riverkeeper Foundation, Inc. (Catawba Riverkeeper) filed a separate action in the United States Court for the Western District of North Carolina. The lawsuit contends the state enforcement action discussed above does not adequately address issues raised in Catawba Riverkeeper’s notice of intent to sue relating to the Riverbend Steam Station. On April 11, 2014, the Court denied Catawba Riverkeeper’s objections to the Magistrate Judge’s recommendation that plaintiff’s case be dismissed as well as Duke Energy Carolinas’ motion to dismiss. The Court allowed limited discovery, after which Duke Energy Carolinas may file any renewed motions to dismiss.
On September 12, 2013, Cape Fear River Watch, Inc., Sierra Club and Waterkeeper Alliance filed a citizen suit in the Federal District Court for the Eastern District of North Carolina. The lawsuit alleges unpermitted discharges to surface water and groundwater violations at the Sutton Plant. On June 9, 2014, the court granted Duke Energy Progress' request to dismiss the groundwater claims but rejected its request to dismiss the surface water claims. In response to a motion filed by the SELC, on August 1, 2014, the court modified the original June 9order to dismiss only the plaintiff's federal law claim based on hydrologic connections at Sutton Lake. The claims related to the alleged state court violations of the permits are back in the case.
On September 3, 2014, three cases were filed by various environmental groups: (i) a citizen suit in the United States Court for the Middle District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the Cape Fear Plant; (ii) a citizen suit in the United States Court for the Eastern District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the H.F. Lee Plant; and (iii) a citizen suit in the United States Court for the Middle District of North Carolina alleging unpermitted discharges to surface water and groundwater violations at the Buck Steam Station. Motions to Stay or Dismiss the proceedings were filed in each of the three cases. The proceedings related to Cape Fear and H.F. Lee have been stayed. A hearing was held August 5, 2015 on the motion relating to Buck.
It is not possible to predict whether Duke Energy Carolinas or Duke Energy Progress will incur any liability or to estimate the damages, if any, they might incur in connection with these matters.
North Carolina Ash Basin Grand Jury Investigation
As a result of the Dan River ash basin water release discussed above, DENR issued a Notice of Violation and Recommendation of Assessment of Civil Penalties with respect to this matter on February 28, 2014, which the company responded to on March 13, 2014. Duke Energy and certain Duke Energy employees received subpoenas issued by the United States Attorney for the Eastern District of North Carolina in connection with a criminal investigation related to all 14 of the North Carolina facilities with ash basins and the nature of Duke Energy's contacts with DENR with respect to those facilities. This is a multidistrict investigation that also involves state law enforcement authorities.

On February 20, 2015, Duke Energy Carolinas, Duke Energy Progress and Duke Energy Business Services LLC (DEBS), a wholly owned subsidiary of Duke Energy, each entered into Plea Agreements in connection with the investigation initiated by the United States Department of Justice Environmental Crimes Section and the United States Attorneys for the Eastern District of North Carolina, the Middle District of North Carolina and the Western District of North Carolina (collectively, USDOJ). On May 14, 2015, the United States District Court for the Eastern District of North Carolina approved the Plea Agreements.
Under the Plea Agreements, DEBS and Duke Energy Progress pleaded guilty to four misdemeanor CWA violations related to violations at Duke Energy Progress’ H.F. Lee Steam Electric Plant, Cape Fear Steam Electric Plant and Asheville Steam Electric Generating Plant. Duke Energy Carolinas and DEBS pleaded guilty to five misdemeanor CWA violations related to violations at Duke Energy Carolinas’ Dan River Steam Station and Riverbend Steam Station. DEBS, Duke Energy Carolinas and Duke Energy Progress also agreed (i) to a five-year probation period, (ii) to pay a total of approximately $68 million in fines and restitution and $34 million for community service and mitigation (the Payments), (iii) to fund and establish environmental compliance plans subject to the oversight of a court-appointed monitor in addition to certain other conditions set out in the Plea Agreements. Duke Energy Carolinas and Duke Energy Progress also agree to each maintain $250 million under their Master Credit Facility as security to meet their obligations under the Plea Agreements. Payments under the Plea Agreements will be borne by shareholders and are not tax deductible. Duke Energy Corporation has agreed to issue a guarantee of all payments and performance due from DEBS, Duke Energy Carolinas and Duke Energy Progress, including but not limited to payments for fines, restitution, community service, mitigation and the funding of, and obligations under, the environmental compliance plans. Payment of the amounts relating to fines and restitution were made between May and July 2015. Duke Energy Carolinas and Duke Energy Progress have remaining liabilities of $18 million and $16 million, respectively, within Accounts payable on the Condensed Consolidated Balance Sheets as of June 30, 2015.
On May 14, 2015, Duke Energy reached an Interim Administrative Agreement with the U.S. Environmental Protection Agency Office of Suspension and Debarment that avoids debarment of DEBS, Duke Energy Carolinas or Duke Energy Progress with respect to all active generating facilities. The Interim Administrative Agreement imposes a number of requirements relating to environmental and ethical compliance, subject to the oversight of an independent monitor. The Plea Agreements do not cover pending civil claims related to the Dan River coal ash release and operations at other North Carolina coal plants.
Potential Groundwater Contamination Claims
Beginning in May 2015, a number of residents living in the vicinity of the North Carolina facilities with ash basins received letters from DENR advising them not to drink water from the private wells on their land tested by DENR as the samples were found to have certain substances at levels higher than the criteria set by the North Carolina Department of Health and Human Services. The criteria, in some cases, are considerably more stringent than federal drinking water standards established to protect human health and welfare. The Coal Ash Act requires additional groundwater monitoring and assessments for each of the 14 coal-fired plants in North Carolina, including sampling of private water supply wells. The data gathered through these comprehensive groundwater assessments will be used to determine whether the water quality of these private water supply wells has been adversely impacted by the ash basins. The first of these groundwater assessments was submitted to DENR on August 5, 2015. It is not possible to estimate the maximum exposure of loss, if any, that may occur in connection with claims which might be made by these residents.
Duke Energy Carolinas
New Source Review
In 1999-2000, the U.S. Department of Justice (DOJ) on behalf of the EPA filed a number of complaints and notices of violation against multiple utilities, including Duke Energy Carolinas, for alleged violations of the New Source Review (NSR) provisions of the Clean Air Act (CAA). The government alleges the utilities violated the CAA when undertaking certain maintenance and repair projects at certain coal plants without (i) obtaining NSR permits and (ii) installing the best available emission controls for sulfur dioxide, nitrogen oxide and particulate matter. The complaints seek the installation of pollution control technology on generating units that allegedly violated the CAA, and unspecified civil penalties in amounts of up to $37,500 per day for each violation. Duke Energy Carolinas asserts there were no CAA violations because the applicable regulations do not require NSR permitting in cases where the projects undertaken are “routine” or otherwise do not result in a net increase in emissions.
In 2000, the government sued Duke Energy Carolinas in the U.S. District Court in Greensboro, North Carolina, claiming NSR violations for 29 projects performed at 25 of Duke Energy Carolinas’ coal-fired units. Duke Energy Carolinas asserts the projects were routine and not projected to increase emissions. The parties subsequently filed a stipulation agreeing to dismiss with prejudice all but 13 claims at 13 generating units, 11 of which have since been retired. Trial date has been set for October 2015. It is not possible to predict whether Duke Energy Carolinas will incur any liability or to estimate the damages, if any, it might incur in connection with this matter. Ultimate resolution of these matters could have a material effect on the results of operations, cash flows or financial position of Duke Energy Carolinas. However, the appropriate regulatory recovery will be pursued for costs incurred in connection with such resolution.
Asbestos-related Injuries and Damages Claims
Duke Energy Carolinas has experienced numerous claims for indemnification and medical cost reimbursement related to asbestos exposure. These claims relate to damages for bodily injuries alleged to have arisen from exposure to or use of asbestos in connection with construction and maintenance activities conducted on its electric generation plants prior to 1985. As of June 30, 2015, there were 133 asserted claims for non-malignant cases with the cumulative relief sought of up to $34 million, and 66 asserted claims for malignant cases with the cumulative relief sought of up to $10 million. Based on Duke Energy Carolinas’ experience, it is expected that the ultimate resolution of most of these claims likely will be less than the amount claimed.

Duke Energy Carolinas has recognized asbestos-related reserves of $564 million at June 30, 2015 and $575 million at December 31, 2014. These reserves are classified in Other within Deferred Credits and Other Liabilities and Other within Current Liabilities on the Condensed Consolidated Balance Sheets. These reserves are based upon the minimum amount of the range of loss for current and future asbestos claims through 2033, are recorded on an undiscounted basis and incorporate anticipated inflation. In light of the uncertainties inherent in a longer-term forecast, management does not believe they can reasonably estimate the indemnity and medical costs that might be incurred after 2033 related to such potential claims. It is possible Duke Energy Carolinas may incur asbestos liabilities in excess of the recorded reserves.

Duke Energy Florida
Westinghouse Contract Litigation
On March 28, 2014, Duke Energy Florida filed a lawsuit against Westinghouse in the U.S. District Court for the Western District of North Carolina. The lawsuit seeks recovery of $54 million in milestone payments in excess of work performed under the terminated engineering, procurement and construction agreement (EPC) for Levy as well as a determination by the court of the amounts due to Westinghouse as a result of the termination of the EPC.
On March 31, 2014, Westinghouse filed a lawsuit against Duke Energy Florida in U.S. District Court for the Western District of Pennsylvania. The Pennsylvania lawsuit alleged damages under the EPC in excess of $510 million for engineering and design work, costs to end supplier contracts and an alleged termination fee.
On June 9, 2014, the judge in the North Carolina case ruled that the litigation will proceed in the Western District of North Carolina. In November 2014, Westinghouse filed a Motion for Partial Judgment on the pleadings, which was denied on March 30, 2015. Trial is set for February 2016. It is not possible to predict the outcome of the litigation and whether Duke Energy Florida will incur any liability for terminating the EPC or to estimate the damages, if any, it might incur in connection with these matters. Ultimate resolution of these matters could have a material effect on the results of operations, financial position or cash flows of Duke Energy Florida. However, appropriate regulatory recovery will be pursued for the retail portion of any costs incurred in connection with such resolution.

7. ASSET RETIREMENT OBLIGATIONS
COAL COMBUSTION RESIDUALS
In April 2015,accordance with ASC 410-20, Asset Retirement and Environmental Obligations - Asset Retirement Obligations, Duke Energy paid down its outstanding commercial paper by approximately $1.3 billion usingrecords an asset retirement obligation (ARO) when it has a portionlegal obligation that can be reasonably estimated to incur retirement costs associated with the retirement of a long-lived asset. 
On April 17, 2015, the EPA published in the Federal Register a rule to regulate the disposal of CCR from electric utilities as solid waste. The federal regulation, which becomes effective six months after publication, classifies CCR as nonhazardous waste under Subtitle D of the proceeds fromResource Conservation and Recovery Act and allows beneficial use of CCRs with some restrictions. The regulation applies to all new and existing landfills, new and existing surface impoundments, structural fills and CCR piles. The rule establishes requirements regarding landfill design, structural integrity design and assessment criteria for surface impoundments, groundwater monitoring and protection procedures and other operational and reporting procedures to ensure the salesafe disposal and management of CCR. In addition to the requirements of the nonregulated Midwest generation business. See Note 2 for additional information.
On February 20, 2015,federal CCR regulation, CCR landfills and surface impoundments will continue to be independently regulated by most states. Duke Energy Carolinas, Progress Energy, Duke Energy Progress, and DEBS, a wholly owned subsidiary of Duke Energy each entered into Plea Agreements in connection with the investigation initiated by the USDOJ. Duke Energy CarolinasOhio and Duke Energy ProgressIndiana were impacted by the EPA rule and recorded additional asset retirement obligation amounts during the second quarter of 2015.
The ARO amount recorded that relates to the EPA rule was based upon estimated closure costs for ash basins at seven plants located in South Carolina, Indiana and Kentucky. The amount recorded represents the discounted cash flows for estimated closure costs of these ash basins based upon probability weightings of the potential closure methods as evaluated on a site by site basis. Actual costs to be incurred will be dependent upon factors that vary from site to site. The most significant factors are requiredthe method and time frame of closure at the individual sites. Closure methods considered include removing the water from the basins and capping the ash with a synthetic barrier, excavating and relocating the ash to each maintain $250 milliona lined structural fill or lined landfill, or recycling the ash for concrete or some other beneficial use. The ultimate method and timetable for closure will be in compliance with standards set by the EPA rule and any current or future state regulation. The ARO amount will be adjusted as additional information is gained through the closure process, including acceptance and approval of available capacity undercompliance approaches which may change management assumptions, and may result in a material change to the Master Credit Facility as security to meet their obligations under the Plea Agreements, in addition to certain other conditions. The Plea Agreements are subject to court approval. See Note 5 for further details.balance.

9.10. DERIVATIVES AND HEDGING
The Duke Energy Registrants use commodity and interest rate contracts to manage commodity price and interest rate risks. The primary use of energy commodity derivatives is to hedge the generation portfolio against changes in the prices of electricity and natural gas. Interest rate swaps are used to manage interest rate risk associated with borrowings.
All derivative instruments not identified as NPNS are recorded at fair value as assets or liabilities on the Condensed Consolidated Balance Sheets. Cash collateral related to derivative instruments executed under master netting agreement is offset against the collateralized derivatives on the balance sheet. The cash impacts of settled derivatives are recorded as operating activities on the Condensed Consolidated Statements of Cash Flows.
Changes in the fair value of derivative agreementsinstruments that either do not qualify for or have not been designated as hedges are reflected in current earnings or as regulatory assets or liabilities.
FAIR VALUE AND CASH FLOW HEDGES
For a derivative designated as hedging the exposure to variable cash flows of a future transaction, referred to as a cash flow hedge, the effective portion of the derivative's gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings once the future transaction effects earnings. Gains and losses reclassified out of AOCI for the three and six months ended June 30, 2015 and 2014 were immaterial.
Amounts for interest rate contracts are reclassified to earnings as interest expense over the term of the related debt.
At June 30, 2015, there were no open commodity derivative instruments designated as hedges.
COMMODITY PRICE RISK
The Duke Energy Registrants are exposed to the impact of changes in the future prices of electricity, coal and natural gas. Exposure to commodity price risk is influenced by a number of factors including the term of contracts, the liquidity of markets and delivery locations.
Fair ValueRegulated public utilities may have cost-based rate regulations and Cash Flow Hedges
At March 31, 2015, there were no openvarious other cost recovery mechanisms that result in a limited exposure to market volatility of commodity fuel prices. Financial derivative instruments designated as hedges.contracts, where approved by the respective state regulatory commission, can be used to manage the risk of price volatility. Wholesale generating capacity used to sell electricity results in exposure to market volatility in energy-related commodity prices.
Undesignated Contracts
Undesignated contracts may include contracts not designated as a hedge because they are accounted for under Regulated Operations accounting, contracts that do not qualify for hedge accounting, derivatives that do not or no longer qualify for the NPNS scope exception, and de-designated hedge contracts.
Mark-to-market gains or losses on contracts accounted for under Regulated Operations are deferred and recorded as Regulatory Liabilities or Regulatory Assets, respectively. The Subsidiary Registrants utilize cost-tracking mechanisms, commonly referred to as fuel adjustment clauses. These clauses allow for the recovery of fuel and fuel-related costs, including settlements of undesignated derivatives for fuel commodities, and portions of purchased power costs through surcharges on customer rates. The difference between the costs incurred and the surcharge revenues is recorded as an adjustment to Fuel used in electric generation and purchased power – regulated or as Operating Revenues – Regulated electric on the Consolidated Statements of Operations with an offsetting impact on regulatory assets or liabilities. Therefore, due to the regulatory accounting followed by our Regulated Operations for undesignated derivatives, realized and unrealized gains and losses on undesignated derivatives do not have an immediate impact on reported net income.
Mark-to-market gains and losses related to the nonregulated Midwest generation business are recorded in discontinued operations and open positions at April 2, 2015 were included in the sale of the Disposal Group. Refer to Note 2 for further information on the sale of the Disposal Group. Gains and losses on undesignated derivative contracts for nonregulated continuing operations is immaterial, including electric contracts used to hedge renewables generation in Electric Reliability Council of Texas (ERCOT), hedges for a business that is winding down by the end of 2016, and revenues during 2014 for mitigation contracts which were terminated by December 31, 2014.
Undesignated contracts expire as late as 2018.

INTEREST RATE RISK
The Duke Energy Registrants are exposed to changes in interest rates as a result of their issuance or anticipated issuance of variable-rate and fixed-rate debt and commercial paper. Interest rate risk is managed by limiting variable-rate exposures to a percentage of total debt and by monitoring changes in interest rates. To manage risk associated with changes in interest rates, the Duke Energy Registrants may enter into interest rate swaps, U.S. Treasury lock agreements and other financial contracts. In anticipation of certain fixed-rate debt issuances, a series of forward starting interest rate swaps may be executed to lock in components of current market interest rates. These instruments are later terminated prior to or upon the issuance of the corresponding debt. Pretax gains or losses recognized from inception to termination of the hedges are amortized as a component of interest expense over the life of the debt.
Duke Energy has a combination foreign exchange, pay fixed-receive floatingDuke’s interest rate swapswaps for its Regulated Utilities operations employ Regulated Operations accounting. Regulated Operations accounting records the Mark-to-Market on the swaps as Regulatory Assets or Regulatory Liabilities. The accrual of interest on the swaps is recorded as Interest Expense. Regulatory assets and liabilities are amortized consistent with the treatment of the related costs in the ratemaking process.

10.11. INVESTMENTS IN DEBT AND EQUITY SECURITIES
The Duke Energy Registrants classify their investments in debt and equity securities as either trading or available-for-sale.
TRADING SECURITIES
Investments in debt and equity securities held in grantor trusts associated with certain deferred compensation plans and certain other investments are classified as trading securities. These investments were sold prior to June 30, 2015. The fair value of these investments was $10 million at March 31, 2015 and $7 million at December 31, 2014.
AVAILABLE-FOR-SALE SECURITIES
All other investments in debt and equity securities are classified as available-for-sale securities.
Duke Energy’s available-for-sale securities are primarily comprised of investments held in (i) the Nuclear Decommissioning Trust Fund (NDTF) at Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida, (ii) grantor trusts at Duke Energy Progress, Duke Energy Florida and Duke Energy Indiana related to other post-retirement benefit obligations (OPEB) plans, (iii) Duke Energy’s captive insurance investment portfolio and (iv) Duke Energy’s foreign operations investment portfolio.
Duke Energy classifies all other investments in debt and equity securities as long-term,long term, unless otherwise noted.

Investment Trusts
The investments within the NDTF at Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida and the Duke Energy Progress, Duke Energy Florida and Duke Energy Indiana grantor trusts (Investment Trusts) are managed by independent investment managers with discretion to buy, sell and invest pursuant to the objectives set forth by the trust agreements. The Duke Energy Registrants have limited oversight of the day-to-day management of these investments. As a result, the ability to hold investments in unrealized loss positions is outside the control of the Duke Energy Registrants. Accordingly, all unrealized losses associated with debt and equity securities within the Investment Trusts are considered other-than-temporary impairments and are recognized immediately. Pursuant to regulatory accounting, substantially all realized and unrealized gains and losses associated with investments within the Investment Trusts are deferred as a regulatory asset or liability. As a result, there is no immediate impact on earnings of the Duke Energy Registrants.
Other Available-for-Sale Securities
Unrealized gains and losses on all other available-for-sale securities are included in other comprehensive income until realized, unless it is determined the carrying value of an investment is other-than-temporarily impaired. If an other-than-temporary impairment exists, the unrealized loss is included in earnings based on the criteria discussed below.
The Duke Energy Registrants analyze all investment holdings each reporting period to determine whether a decline in fair value should be considered other-than-temporary. Criteria used to evaluate whether an impairment associated with equity securities is other-than-temporary includes, but is not limited to, (i) the length of time over which the market value has been lower than the cost basis of the investment, (ii) the percentage decline compared to the cost of the investment and (iii) management’s intent and ability to retain its investment for a period of time sufficient to allow for any anticipated recovery in market value. If a decline in fair value is determined to be other-than-temporary, the investment is written down to its fair value through a charge to earnings.

If the entity does not have an intent to sell a debt security and it is not more likely than not management will be required to sell the debt security before the recovery of its cost basis, the impairment write-down to fair value would be recorded as a component of other comprehensive income, except for when it is determined a credit loss exists. In determining whether a credit loss exists, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than the amortized cost basis, (ii) changes in the financial condition of the issuer of the security, or in the case of an asset-backed security, the financial condition of the underlying loan obligors, (iii) consideration of underlying collateral and guarantees of amounts by government entities, (iv) ability of the issuer of the security to make scheduled interest or principal payments and (v) any changes to the rating of the security by rating agencies. If a credit loss exists, the amount of impairment write-down to fair value is split between credit loss and other factors. The amount related to credit loss is recognized in earnings. The amount related to other factors is recognized in other comprehensive income. There were no credit losses as of March 31, 2015 and December 31, 2014. There were no other-than-temporary impairments for debt or equity securities as of March 31,June 30, 2015 and December 31, 2014.

11.12. FAIR VALUE MEASUREMENTS
Fair value is the exchange price to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. The fair value definition focuses on an exit price versus the acquisition cost. Fair value measurements use market data or assumptions market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs may be readily observable, corroborated by market data or generally unobservable. Valuation techniques maximize the use of observable inputs and minimize use of unobservable inputs. A midmarket pricing convention (the midpoint price between bid and ask prices) is permitted for use as a practical expedient.
Fair value measurements are classified in three levels based on the fair value hierarchy:
Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. An active market is one in which transactions for an asset or liability occur with sufficient frequency and volume to provide ongoing pricing information.
Level 2 – A fair value measurement utilizing inputs other than quoted prices included in Level 1 that are observable, either directly or indirectly, for an asset or liability. Inputs include (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in markets that are not active and (iii) inputs other than quoted market prices that are observable for the asset or liability, such as interest rate curves and yield curves observable at commonly quoted intervals, volatilities and credit spreads. A Level 2 measurement cannot have more than an insignificant portion of its valuation based on unobservable inputs. Instruments in this category include non-exchange-traded derivatives, such as over-the-counter forwards, swaps and options; certain marketable debt securities; and financial instruments traded in less than active markets.
Level 3 – Any fair value measurement which includes unobservable inputs for more than an insignificant portion of the valuation. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. Level 3 measurements may include longer-term instruments that extend into periods in which observable inputs are not available.
The fair value accounting guidance permits entities to elect to measure certain financial instruments that are not required to be accounted for at fair value, such as equity method investments or the company’s own debt, at fair value. The Duke Energy Registrants have not elected to record any of these items at fair value.

Transfers between levels represent assets or liabilities that were previously (i) categorized at a higher level for which the inputs to the estimate became less observable or (ii) classified at a lower level for which the inputs became more observable during the period. The Duke Energy Registrant’s policy is to recognize transfers between levels of the fair value hierarchy at the end of the period. There were no transfers between levels 1 and 2 during the three and six months ended March 31,June 30, 2015 and 2014. Transfers out of Level 3 during the three and six months ended March 31,June 30, 2015 are the result of forward commodity prices becoming observable due to the passage of time.
Valuation methods of the primary fair value measurements disclosed below are as follows.
Investments in equity securities 
The majority of investments in equity securities are valued using Level 1 measurements. Investments in equity securities are typically valued at the closing price in the principal active market as of the last business day of the quarter. Principal active markets for equity prices include published exchanges such as Nasdaq composite (NASDAQ) and New York Stock Exchange (NYSE). Foreign equity prices are translated from their trading currency using the currency exchange rate in effect at the close of the principal active market. There was no after-hours market activity that was required to be reflected in the reported fair value measurements. Investments in equity securities that are Level 2 or 3 are typically ownership interests in commingled investment funds.
Investments in debt securities
With the exception of U.S. Treasuries which are classified as Level 1, most investments in debt securities are valued using Level 2 measurements because the valuations use interest rate curves and credit spreads applied to the terms of the debt instrument (maturity and coupon interest rate) and consider the counterparty credit rating. If the market for a particular fixed income security is relatively inactive or illiquid, the measurement is Level 3.
Commodity derivatives
Commodity derivatives with clearinghouses are classified as Level 1. Other commodity derivatives are primarily fair valued using internally developed discounted cash flow models which incorporate forward price, adjustments for liquidity (bid-ask spread) and credit or non-performancenonperformance risk (after reflecting credit enhancements such as collateral), and are discounted to present value. Pricing inputs are derived from published exchange transaction prices and other observable data sources. In the absence of an active market, the last available price may be used. If forward price curves are not observable for the full term of the contract and the unobservable period had more than an insignificant impact on the valuation, the commodity derivative is classified as Level 3. In isolation, increases (decreases) in natural gas forward prices result in favorable (unfavorable) fair value adjustments for natural gas purchase contracts; and increases (decreases) in electricity forward prices result in unfavorable (favorable) fair value adjustments for electricity sales contracts. Duke Energy regularly evaluates and validates pricing inputs used to estimate fair value of natural gas commodity contracts by a market participant price verification procedure. This procedure provides a comparison of internal forward commodity curves to market participant generated curves.
Interest rate derivatives
Most over-the-counter interest rate contract derivatives are valued using financial models which utilize observable inputs for similar instruments and are classified as Level 2. Inputs include forward interest rate curves, notional amounts, interest rates and credit quality of the counterparties.
Goodwill, Long-lived Assets and Assets Held for Sale
See Note 78 for a discussion of the valuation of goodwill and long-lived assets and Note 2 related to the assets and related liabilities of the Disposal Group classified as held for sale.

The following tables provide recorded balances for assets and liabilities measured at fair value on a recurring basis on the Condensed Consolidated Balance Sheets. Derivative amounts in the table below exclude cash collateral, which is disclosed in Note 9.10. See Note 1011 for additional information related to investments by major security type.

12.13. VARIABLE INTEREST ENTITIES
A VIE is an entity that is evaluated for consolidation using more than a simple analysis of voting control. The analysis to determine whether an entity is a VIE considers contracts with an entity, credit support for an entity, the adequacy of the equity investment of an entity and the relationship of voting power to the amount of equity invested in an entity. This analysis is performed either upon the creation of a legal entity or upon the occurrence of an event requiring reevaluation, such as a significant change in an entity’s assets or activities. A qualitative analysis of control determines the party that consolidates a VIE. This assessment is based on (i) what party has the power to direct the activities of the VIE that most significantly impact its economic performance and (ii) what party has rights to receive benefits or is obligated to absorb losses that could potentially be significant to the VIE. The analysis of the party that consolidates a VIE is a continual reassessment.
No financial support was provided to any of the consolidated VIEs during the threesix months ended March 31,June 30, 2015 and the year ended December 31, 2014, or is expected to be provided in the future, that was not previously contractually required.

DERF / DEPR / DEFR
Duke Energy Receivables Finance Company, LLC (DERF), DEPR and DEFR are bankruptcy remote, special purpose subsidiaries of Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida, respectively. On a daily basis, DERF, DEPR and DEFR buy certain accounts receivable arising from the sale of electricity and/or related services from their parent companies. DERF, DEPR and DEFR are wholly owned limited liability companies with separate legal existence from their parents, and their assets are not generally available to creditors of their parent companies. DERF, DEPR and DEFR borrow amounts under credit facilities to buy the receivables. Borrowing availability is limited to the amount of qualified receivables sold, which is generally expected to be in excess of the credit facilities. The credit facilities are reflected on the Condensed Consolidated Balance Sheets as Long-Term Debt. The secured credit facilities were not structured to meet the criteria for sale accounting treatment under the accounting guidance for transfers and servicing of financial assets.

The activity that most significantly impacts the economic performance of DERF, DEPR and DEFR are the decisions made to manage delinquent receivables. Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida consolidate DERF, DEPR and DEFR, respectively, as they are the related parties most closely associated with the VIE.
CRC
On a revolving basis, CRC buys certain accounts receivable arising from the sale of electricity and/or related services from Duke Energy Ohio and Duke Energy Indiana. Receivables sold are securitized by CRC through a credit facility managed by two unrelated third parties. The proceeds Duke Energy Ohio and Duke Energy Indiana receive from the sale of receivables to CRC are typically 75 percent cash and 25 percent in the form of a subordinated note from CRC. The subordinated note is a retained interest in the receivables sold. Cash collections from the receivables are the sole source of funds to satisfy the related debt obligation. Depending on experience with collections, additional equity infusions to CRC may be required by Duke Energy to maintain a minimum equity balance of $3 million. Borrowing availability is limited to the amount of qualified receivables sold, which is generally expected to be in excess of the credit facility. The credit facility expires in November 2016 and is reflected on the Condensed Consolidated Balance Sheets as Long-Term Debt.
CRC is considered a VIE because (i) equity capitalization is insufficient to support its operations, (ii) power to direct the activities that most significantly impact the economic performance of the entity are not performed by the equity holder, Cinergy, and (iii) deficiencies in net worth of CRC are not funded by Cinergy, but by Duke Energy. The most significant activities of CRC are decisions made related to the management of delinquent receivables. Duke Energy consolidates CRC as it makes these decisions. Neither Duke Energy Ohio nor Duke Energy Indiana consolidate CRC.
Renewables
Certain of Duke Energy’s renewable energy facilities are VIEs due to long-term fixed-price power purchase agreements. These fixed-price agreements effectively transfer commodity price risk to the buyer of the power. Certain other of Duke Energy’s renewable energy facilities are VIEs due to Duke Energy issuing guarantees for debt service and operations and maintenance reserves in support of debt financings. For certain VIEs, assets are restricted and cannot be pledged as collateral or sold to third parties without prior approval of debt holders. The activities that most significantly impact the economic performance of these renewable energy facilities were decisions associated with siting, negotiating purchase power agreements, engineering, procurement and construction, and decisions associated with ongoing operations and maintenance-related activities. Duke Energy consolidates the entities as it makes all of these decisions.
NON-CONSOLIDATED VIEs

The Duke Energy Registrants are not aware of any situations where the maximum exposure to loss significantly exceeds the carrying values shown above except for the power purchase agreement with OVEC, which is discussed below, and various guarantees, reflected in the table above as Deferred credits and other liabilities. For more information on various guarantees, refer to Note 5, "Commitments and Contingencies".Contingencies."
Renewables
Duke Energy has investments in various renewable energy project entities. Some of these entities are VIEs due to long-term fixed-price power purchase agreements. These fixed-price agreements effectively transfer commodity price risk to the buyer of the power. Duke Energy does not consolidate these VIEs because power to direct and control key activities is shared jointly by Duke Energy and other owners.
Other
Duke Energy holds a 50 percent equity interest in Duke-American Transmission Company, LLC (DATC). DATC is considered a VIE due to insufficient equity at risk to permit DATC to finance its own activities without additional subordinated financial support. The activities that most significantly impact DATC’s economic performance are the decisions related to investing in existing and development of new transmission facilities. The power to direct these activities is jointly and equally shared by Duke Energy and the other joint venture partner and, therefore, Duke Energy does not consolidate.

Duke Energy has a 40 percent equity interest and a 7.5 percent equity interest in ACP which isand Sabal Trail Transmission, LLC (Sabal Trail), respectively. These entities are considered a VIEVIEs as thetheir equity is not sufficient to permit the entityentities to finance itstheir activities without additional subordinated financial support. The activity that most significantly impacts the economic performance of both ACP and Sabal Trail is construction. Duke Energy does not control these activities and therefore does not consolidate ACP.ACP or Sabal Trail.

OVEC
Duke Energy Ohio’s 9 percent ownership interest in OVEC is considered a non-consolidated VIE. Through its ownership interest in OVEC, Duke Energy Ohio has a contractual arrangement to buy power from OVEC’s power plants through June 2040. Proceeds from the sale of power by OVEC to its power purchase agreement counterparties are designed to be sufficient to meet its operating expenses, fixed costs, debt amortization and interest expense, as well as earn a return on equity. Accordingly, the value of this contract is subject to variability due to fluctuations in power prices and changes in OVEC’s costs of business, including costs associated with its 2,256 MW of coal-fired generation capacity. Proposed environmental rule-making could increase the costs of OVEC, which would be passed through to Duke Energy Ohio. In 2014, Duke Energy Ohio recorded a $94 million impairment related to OVEC.
CRC
See discussion under Consolidated VIEs for additional information related to CRC.
Amounts included in Receivables in the above table for Duke Energy Ohio and Duke Energy Indiana reflect their retained interest in receivables sold to CRC. These subordinated notes held by Duke Energy Ohio and Duke Energy Indiana are stated at fair value. Carrying values of retained interests are determined by allocating carrying value of the receivables between assets sold and interests retained based on relative fair value. The allocated bases of the subordinated notes are not materially different than their face value because (i) the receivables generally turnover in less than two months, (ii) credit losses are reasonably predictable due to the broad customer base and lack of significant concentration, and (iii) the equity in CRC is subordinate to all retained interests and thus would absorb losses first. The hypothetical effect on fair value of the retained interests assuming both a 10 percent and a 20 percent unfavorable variation in credit losses or discount rates is not material due to the short turnover of receivables and historically low credit loss history. Interest accrues to Duke Energy Ohio and Duke Energy Indiana on the retained interests using the acceptable yield method. This method generally approximates the stated rate on the notes since the allocated basis and the face value are nearly equivalent. An impairment charge is recorded against the carrying value of both retained interests and purchased beneficial interest whenever it is determined that an other-than-temporary impairment has occurred.

Cash flows from sales of receivables are reflected within Operating Activities on Duke Energy Ohio’s and Duke Energy Indiana’s Condensed Consolidated Statements of Cash Flows.
Collection fees received in connection with servicing transferred accounts receivable are included in Operation, maintenance and other on Duke Energy Ohio’s and Duke Energy Indiana’s Condensed Consolidated Statements of Operations and Comprehensive Income. The loss recognized on sales of receivables is calculated monthly by multiplying receivables sold during the month by the required discount. The required discount is derived monthly utilizing a three-year weighted averageweighted-average formula that considers charge-off history, late charge history and turnover history on the sold receivables, as well as a component for the time value of money. The discount rate, or component for the time value of money, is the prior month-end London Interbank Offered Rate (LIBOR) plus a fixed rate of 1.00 percent.
13.14. COMMON STOCK
Basic Earnings Per Share (EPS) is computed by dividing net income attributable to Duke Energy common shareholders, adjusted for distributed and undistributed earnings allocated to participating securities, by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income attributable to Duke Energy common shareholders, as adjusted for distributed and undistributed earnings allocated to participating securities, by the diluted weighted-average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other agreements to issue common stock, such as stock options, phantom shares and stock-based performance unit awards, were exercised or settled. Duke Energy’s participating securities are restricted stock units that are entitled to dividends declared on Duke Energy common shares during the restricted stock unit’s vesting periods.

The total fair market value of the delivered shares, based on the closing Duke Energy stock price of $76.97 per share at the commencement of the ASR, was $1.275 billion. The final number of shares to be repurchased is dependent upon the average of the daily volume-weighted average stock prices of Duke Energy’s common stock during the term of the program, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR agreements. The delivery of additional shares of common stock to Duke Energy or delivery of shares of common stock or cash payment, at Duke Energy’s election, to the Dealers from Duke Energy may be required under certain circumstances. Final settlement of the ASR transaction is expected to occur by the end of the third quarter of 2015.

16. EMPLOYEE BENEFIT PLANS
DEFINED BENEFIT RETIREMENT PLANS
Duke Energy maintains, and the Subsidiary Registrants participate in, qualified, non-contributory defined benefit retirement plans. The plans cover most U.S. employees using a cash balance formula. Under a cash balance formula, a plan participant accumulates a retirement benefit consisting of pay credits equal to a percentage of current eligible earnings based on age and/or years of service, and interest credits. Certain employees are covered under plans that use a final average earnings formula. Under these average earnings formulas, a plan participant accumulates a retirement benefit equal to the sum of percentages of their (i) highest three-year or four-year average earnings, (ii) highest three-year or four-year average earnings in excess of covered compensation per year of participation (maximum of 35 years) and/or (iii) highest three-year or four-year average earnings times years of participation in excess of 35 years. Duke Energy also maintains, and the Subsidiary Registrants participate in, non-qualified, non-contributory defined benefit retirement plans which cover certain executives. As of January 1, 2014, theThe qualified and non-qualified, non-contributory defined benefit plans are closed to new and rehired non-union and certain unionized employees.

EMPLOYEE SAVINGS PLANS
Duke Energy sponsors, and the Subsidiary Registrants participate in, employee savings plans that cover substantially all U.S. employees. Effective January 1, 2015, all then-existing employee savings plans were merged into a single plan. Most employees participate in a matching contribution formula where Duke Energy provides a matching contribution generally equal to 100 percent of employee before-tax and Roth
401(k) contributions of up to 6 percent of eligible pay per pay period. Prior to 2015, Duke Energy also provided a match on after-tax contributions for certain plans. Dividends on Duke Energy shares held by the savings plans are charged to retained earnings when declared and shares held in the plans are considered outstanding in the calculation of basic and diluted earnings per share.
As of January 1, 2014, forFor new and rehired non-union and certain unionized employees who are not eligible to participate in Duke Energy’s defined benefit plans, an additional employer contribution of 4 percent of eligible pay per pay period, subject to three-year vesting, is provided to the employee’s savings plan account.
The following table includes pretax employer matching contributions, as well as the additional contribution of 4 percent of eligible pay per pay period for employees not eligible to participate in a defined benefit plan, made by Duke Energy and expensed by the Subsidiary Registrants.

The increase in the effective tax rate for Duke Energy for the three and six months ended June 30, 2015 is primarily due to a deferred tax benefit related to the merger of two Chilean subsidiaries recorded in second quarter 2014 and a deferred tax charge for changes in apportionment related to state income taxes recorded in second quarter 2015.
The increase in the effective tax rate for Duke Energy Carolinas for the three and six months ended June 30, 2015, is primarily due to favorable audit settlements and changes in apportionment related to state income tax in second quarter 2014.
The increase in the effective tax rate for Progress Energy for the three months ended June 30, 2015, is primarily due to tax levelization.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following combined Management’s Discussion and Analysis of Financial Condition and Results of Operations is separately filed by Duke Energy Corporation (collectively with its subsidiaries, Duke Energy) and Duke Energy Carolinas, LLC (Duke Energy Carolinas), Progress Energy, Inc. (Progress Energy), Duke Energy Progress, Inc.LLC (Duke Energy Progress)Progress, formerly Duke Energy Progress, Inc.), Duke Energy Florida, Inc.LLC (Duke Energy Florida)Florida, formerly Duke Energy Florida, Inc.), Duke Energy Ohio, Inc. (Duke Energy Ohio) and Duke Energy Indiana, Inc. (Duke Energy Indiana) (collectively referred to as the Subsidiary Registrants). However, none of the registrants makes any representation as to information related solely to Duke Energy or the Subsidiary Registrants of Duke Energy other than itself.
DUKE ENERGY
Duke Energy is an energy company headquartered in Charlotte, North Carolina. Duke Energy operates in the United States (U.S.) primarily through its wholly owned subsidiaries, Duke Energy Carolinas, Duke Energy Progress, Duke Energy Florida, Duke Energy Ohio and Duke Energy Indiana, as well as in Latin America.
When discussing Duke Energy’s consolidated financial information, it necessarily includes the results of the Subsidiary Registrants, which, along with Duke Energy, are collectively referred to as the Duke Energy Registrants.
Management’s Discussion and Analysis includes financial information prepared in accordance with generally accepted accounting principles (GAAP) in the U.S., as well as certain non-GAAP financial measures such as adjusted earnings, adjusted diluted earnings per share (EPS) and adjusted segment income, discussed below. Generally, a non-GAAP financial measure is a numerical measure of financial performance, financial position or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP financial measures should be viewed as a supplement to, and not a substitute for, financial measures presented in accordance with GAAP. Non-GAAP measures presented herein may not be comparable to similarly titled measures used by other companies.
Management’s Discussion and Analysis should be read in conjunction with the Condensed Consolidated Financial Statements and Notes for the threesix months ended March 31,June 30, 2015, and with Duke Energy’s Annual Report on Form 10-K for the year ended December 31, 2014.
Midwest Generation Exit
Duke Energy, through indirect subsidiaries, completed the sale of the nonregulated Midwest generation business and Duke Energy Retail Sales LLC (Disposal Group) to a subsidiary of Dynegy Inc. (Dynegy) on April 2, 2015, for approximately $2.8 billion in cash. Refer to Note 2 to the Condensed Consolidated Financial Statements, “Acquisitions and Dispositions,” for additional information on this transaction.
Commercial Portfolio (formerly Commercial Power) builds, develops and operates wind and solar renewable generation and energy transmission projects throughout the continental U.S. The segment was renamed as a result of the sale of the nonregulated Midwest generation business, as discussed in Note 2. For periods subsequent to the sale, beginning in the second quarter of 2015, certain immaterial results of operations and related assets previously presented in the Commercial Portfolio segment are presented in Regulated Utilities and Other.
Accelerated Stock Repurchase Program
On April 6, 2015, Duke Energy entered into agreements with each of Goldman, Sachs & Co. and JPMorgan Chase Bank, National Association (the Dealers) to repurchase a total of $1.5 billion of Duke Energy common stock under an accelerated stock repurchase program (the ASR). Duke Energy made payments of $750 million to each of the Dealers and was delivered 16.6 million shares, with a total fair value of $1.275 billion, which isrepresented approximately 85 percent of the total number of shares of Duke Energy common stock expected to be repurchased under the ASR. The total fair market value$225 million unsettled portion met the criteria to be accounted for as a forward contract indexed to Duke Energy's stock and qualified as an equity instrument. The company recorded the $1.5 billion payment as a reduction to common stock as of April 6, 2015. In June, 2015, the Dealers delivered 3.2 million additional shares based on the closingto Duke Energy stockto complete the ASR. Approximately 19.8 million shares, in total, were delivered to Duke Energy and retired under the ASR at an average price of $76.97$75.75 per share at the commencement of the ASR, was $1.275 billion.share. The final number of shares to be repurchased is dependentwas based upon the average of the daily volume-weighted averagevolume weighted-average stock prices of Duke Energy’s common stock during the term of the program, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR agreements. The delivery of additional shares of common stock to Duke Energy or delivery of shares of common stock or cash payment, at Duke Energy’s election, to the Dealers from Duke Energy may be required under certain circumstances. Final settlement of the ASR transaction is expected to occur by the end of the third quarter of 2015.discount.

PART I

Results of Operations
In this section, Duke Energy provides analysis and discussion of earnings and factors affecting earnings on both a GAAP and non-GAAP basis.
Management evaluates financial performance in part based on the non-GAAP financial measures, adjusted earnings and adjusted diluted EPS. These items are measured as income from continuing operations net of income (loss) attributable to noncontrolling interests, adjusted for the dollar and per-share impact of mark-to-market impacts of economic hedges in the Commercial PowerPortfolio segment and special items including the operating results of the Disposal Group classified as discontinued operations for GAAP purposes. Special items represent certain charges and credits, which management believes will not be recurring on a regular basis, although it is reasonably possible such charges and credits could recur. As result of the agreement in August 2014 to sell the Disposal Group to Dynegy, the operatingOperating results of the Disposal Group sold to Dynegy are classifiedreported as discontinued operations, including a portion of the mark-to-market adjustments associated with derivative contracts. Management believes that including the operating results of the Disposal Group classifiedreported as discontinued operations better reflects its financial performance and therefore has included these results in adjusted earnings and adjusted diluted EPS.EPS prior to the sale of the Disposal Group. Additionally, as a result of completing the sale of the Disposal Group during the second quarter of 2015, state income tax expense increased as state income tax apportionments changed. The additional tax expense was recognized in Continuing Operations on a GAAP basis. This impact to state income taxes has been reflected in Discontinued Operations in the Commercial Portfolio segment for adjusted diluted EPS purposes as management believes these impacts are incidental to the sale of the Disposal Group. Derivative contracts are used in Duke Energy’s hedging of a portion of the economic value of its generation assets in the Commercial PowerPortfolio segment. The mark-to-market impact of derivative contracts is recognized in GAAP earnings immediately and, if associated with the Disposal Group, classified as discontinued operations, as such derivative contracts do not qualify for hedge accounting or regulatory treatment. The economic value of generation assets is subject to fluctuations in fair value due to market price volatility of input and output commodities (e.g., coal, electricity, natural gas). Economic hedging involves both purchases and sales of those input and output commodities related to generation assets. Operations of the generation assets are accounted for under the accrual method. Management believes excluding impacts of mark-to-market changes of the derivative contracts from adjusted earnings until settlement better matches the financial impacts of the derivative contract with the portion of economic value of the underlying hedged asset. Management believes the presentation of adjusted earnings and adjusted diluted EPS provides useful information to investors, as it provides them an additional relevant comparison of Duke Energy’s performance across periods. Management uses these non-GAAP financial measures for planning and forecasting and for reporting results to the Duke Energy Board of Directors (Board of Directors), employees, shareholders, analysts and investors concerning Duke Energy’s financial performance. Adjusted diluted EPS is also used as a basis for employee incentive bonuses. The most directly comparable GAAP measures for adjusted earnings and adjusted diluted EPS are Net Income Attributable to Duke Energy Corporation and Diluted EPS Attributable to Duke Energy Corporation common shareholders, which include the dollar and per-share impact of special items, mark-to-market impacts of economic hedges in the Commercial PowerPortfolio segment and discontinued operations.
Management evaluates segment performance based on segment income. Segment income is defined as income from continuing operations net of income attributable to noncontrolling interests. Segment income, as discussed below, includes intercompany revenues and expenses that are eliminated in the Consolidated Financial Statements. Management also uses adjusted segment income as a measure of historical and anticipated future segment performance. Adjusted segment income is a non-GAAP financial measure, as it is based upon segment income adjusted for the mark-to-market impacts of economic hedges in the Commercial PowerPortfolio segment and special items, including the operating results of the Disposal Group classified as discontinued operations for GAAP purposes. Management believes the presentation of adjusted segment income as presented provides useful information to investors, as it provides them with an additional relevant comparison of a segment’s performance across periods. The most directly comparable GAAP measure for adjusted segment income is segment income, which represents segment income from continuing operations, including any special items and the mark-to-market impacts of economic hedges in the Commercial PowerPortfolio segment.
Duke Energy’s adjusted earnings, adjusted diluted EPS and adjusted segment income may not be comparable to similarly titled measures of another company because other entities may not calculate the measures in the same manner.
See Note 3 to the Condensed Consolidated Financial Statements, “Business Segments,” for a discussion of Duke Energy’s segment structure.

The variance in adjusted earnings for three months ended March 31,June 30, 2015, compared to the same period in 2014, was primarily due to:
Lower results in Latin America primarily due to a prior-year tax benefit related to the reorganization of Chilean operations and higher purchased power costs resulting from the multiyear drought in Brazil;
Higher operations and maintenance expense primarily due to planned increased spending and the prior-year benefit associated with the adoption of nuclear outage levelization, partially offset by lower storm restoration costs;
Higher depreciation and amortization expense primarily due to higher depreciable base; and
The impact of a higher effective income tax rate due to a prior-year state tax settlement that resulted in a favorable adjustment to deferred taxes.
Partially offset by:
Higher weather-normal retail sales volumes;
Favorable weather in 2015 compared to 2014; and
Reduction in shares outstanding due to the Duke Energy stock repurchase (only impacts per diluted share amounts in the tables above).

The variance in adjusted earnings for six months ended June 30, 2015, compared to the same period in 2014, was primarily due to:
Lower results in Latin America primarily due to lower spot market energy sales volume and higher purchased power costs resulting from the multiyear drought in Brazil and a prior-year tax benefit related to the reorganization of Chilean operations;
Higher operations and maintenance expense primarily due to planned increased spending and the prior-year benefit associated with the adoption of nuclear outage levelization, partially offset by lower storm restoration costs;
Higher depreciation and amortization expense primarily due to higher depreciable base; and
Lower margins at National Methanol Company (NMC), largely driven by lower methyl tertiary butyl ether (MTBE) prices.
Partially offset by:
Higher results at the nonregulated Midwest generation business prior to its sale on April 2, 2015, due to higher PJM Interconnection LLC (PJM) capacity revenues and increased generation margins;
Increased wholesale net margins largely due to increases in contracted amounts and prices;
Increased retail pricing primarily due to higher base rates and rate riders in certain jurisdictions, including increased revenues related to energy efficiency programs; and
The impact of a lower effective income tax rate.

The following is a detailed discussion of the variance drivers by line item.
Operating Revenues. The variance was driven primarily by:
A $73a $78 million decrease in fuel revenues driven primarily by overall lower fuel rates for electric retail customers for all jurisdictions, except South Carolina and Florida. Fuel revenues represent sales to retail and wholesale customers;
a $58 million decrease in gross receipts tax revenue due to the N.C.North Carolina Tax Simplification and Rate Reduction Act which terminated the collection of the North Carolina gross receipts tax effective July 1, 2014; and
A $58a $25 million net decrease in retail pricing primarily due to updated rates and rate riders in certain jurisdictions, including decreased revenues related to Duke Energy Florida's nuclear cost recovery clause and energy efficiency programs.
Partially offset by:
a $50 million increase in weather-normal sales volumes to retail customers (net of fuel revenue) reflecting increased demand;
a $27 million increase in electric sales (net of fuel revenue) to retail customers due to favorable weather conditions. (i) For the three months ended June 30, 2015 in the Carolinas, cooling degree days were 15 percent above normal as compared with 10 percent above normal during the same period in 2014. (ii) For the three months ended June 30, 2015 in the Midwest, cooling degree days were 3 percent above normal as compared to the prior year's normal weather. (iii) For the three months ended June 30, 2015 in Florida, cooling degree days were 19 percent above normal as compared with 1 percent above normal during the same period in 2014; and
a $20 million increase in wholesale power revenues, net of sharing, primarily due to additional volumes and capacity charges for customers served under long-term contracts.
Operating Expenses. The variance was driven primarily by:
a $95 million decrease in fuel expense (including purchased power and natural gas purchases for resale) primarily due to (i) lower natural gas and coal prices, and (ii) lower volumes of coal and oil used in electric generation, partially offset by (iii) higher volumes of natural gas used in electric generation; and
a $34 million decrease in property and other taxes primarily due to the termination of the collection of the North Carolina gross receipts tax as mentioned above, partially offset by a favorable 2014 Ohio gas excise tax settlement.

PART I

Partially offset by:
a $95 million increase in operating and maintenance expense primarily due to planned spending and the prior-year benefit associated with the adoption of nuclear outage levelization, partially offset by lower storm restoration costs; and
a $19 million increase in depreciation and amortization expense primarily due to increases in depreciation as a result of additional plant in service.
Income Tax Expense. The variance was primarily due to an increase in the effective tax rate. The effective tax rate for the three months ended June 30, 2015 and 2014 was 37.1 percent and 34.4 percent, respectively. The increase in the effective tax rate is primarily due to favorable audit settlements and changes in apportionment related to state income tax in second quarter 2014.
Six Months Ended June 30, 2015 as Compared to June 30, 2014
Regulated Utilities’ results were impacted by higher operation and maintenance costs, and higher depreciation and amortization expense. These impacts were partially offset by an increase in wholesale power margins, favorable weather, and higher weather-normal sales volumes. The following is a detailed discussion of the variance drivers by line item.
Operating Revenues. The variance was driven primarily by:
a $134 million decrease in fuel revenues driven primarily by overall lower fuel rates for electric retail customers for all jurisdictions, except South Carolina and Florida. Fuel revenues represent sales to retail and wholesale customers; and
A $26a $131 million decrease in weather-normal sales volumesgross receipts tax revenue due to residential retail customers (net of fuel revenue), reflecting decreased demand.the North Carolina Tax Simplification and Rate Reduction Act as mentioned above.
Partially offset by:
A $45a $67 million increase in wholesale power revenues, net of sharing, primarily due to additional volumes and capacity charges for customers served under long-term contracts;
a $24 million increase in electric sales (net of fuel revenue) to retail customers due to favorable weather conditions. (i) For the six months ended June 30, 2015 in the Carolinas, cooling degree days were 14 percent above normal as compared with 8 percent above normal during the same period in 2014, and heating degree days were 12 percent above normal as compared with 15 percent above normal during the same period in 2014. (ii) For the six months ended June 30, 2015 in the Midwest, cooling degree days were 1 percent above normal as compared with 2 percent below normal during the same period in 2014, and heating degree days were 15 percent above normal as compared with 22 percent above normal during the same period in 2014. (iii) For the six months ended June 30, 2015 in Florida cooling degree days were 22 percent above normal as compared with 2 percent below normal during the same period in 2014, and heating degree days were 6 percent below normal as compared with 1 percent above normal during the same period in 2014; and
A $16a $23 million net increase in weather-normal sales volumes to retail pricing primarily due tocustomers (net of fuel revenue) reflecting increased revenues related to energy efficiency programs.demand.
Operating Expenses. The variance was driven primarily by:
A $95a $157 million decrease in fuel expense (including purchased power and natural gas purchases for resale) primarily due to (i) lower natural gas and coal prices, and (ii) lower volumes of coal and oil used in electric generation, partially offset by (iii) higher volumes of natural gas used in electric generation; and
a $129 million decrease in property and other taxes primarily due to the termination of the collection of the North Carolina gross receipts tax as mentioned above, and lower sales and use tax; and

Partially offset by:
A $21a $110 million increase in operating and maintenance expense primarily due to planned spending and the prior-year benefit of the adoption of nuclear outage levelization, partially offset by lower storm restoration costs; and
a $40 million increase in depreciation and amortization expense primarily due to increases in depreciation as a result of additional plant in service and an absence of a prior-year decrease in the reduction of the cost of removal component of amortization expense; and
A $14 million increase in operating and maintenance expense primarily due to higher nuclear costs, including impacts of nuclear outage levelization deferrals and related amortization, higher outage costs at fossil generation stations, and higher maintenance costs for distribution, partially offset by lower storm costs.service.
Income Tax Expense. The variance was primarily due to an increase in pretax income. The effective tax rate for the threesix months ended March 31,June 30, 2015 and 2014 was 36.736.8 percent and 37.536.0 percent, respectively.
Matters Impacting Future Regulated Utilities Results
Duke Energy is a party to multiple lawsuits and could be subject to fines and other penalties related to the Dan River coal ash release and operations at other North Carolina facilities with ash basins. The outcome of these lawsuits and potential fines and penalties could have an adverse impact to Regulated Utilities’ financial position, results of operations and cash flows. See Note 5 to the Condensed Consolidated Financial Statements, “Commitments and Contingencies,” for additional information.
An order from regulatory authorities disallowing recovery of costs related to closure of ash basins could have an adverse impact to the Regulated Utilities' financial position, results of operations and cash flows. See Note 5 to the Condensed Consolidated Financial Statements, “Commitments and Contingencies,” for additional information.

PART I

In 2013, a FERCFederal Energy Regulatory Commission (FERC) Administrative Law Judge issued an initial decision holding that Duke Energy is responsible for costs associated with Multi Value Projects (MVP), a type of Transmission Expansion Planning (MTEP) cost, approved by Midcontinent Independent System Operator, Inc. (MISO) prior to the date of Duke Energy’s withdrawal. The initial decision will be reviewed by the FERC. If the FERC upholds the initial decision, Duke Energy intends to file an appeal in federal court. If Duke Energy is deemed responsible for these unrecovered costs, and if a portionthe Public Utilities Commission of Ohio disallows recovery of these costs, is not eligible for recovery, there maywould be an adverse impact to itsRegulated Utilities' financial position, results of operations and cash flows. See Note 4 to the Condensed Consolidated Financial Statements, “Regulatory Matters,” for additional information.
In 2015, the Indiana Utility Regulatory Commission (IURC) is examining intervenors' allegations regarding the Edwardsport IGCCintegrated gasification combined cycle (IGCC) in-service date for ratemaking purposes, operational performance of the plant, the level of operating costs and financing charges associated with construction delays. The outcome of these proceedings could have an adverse impact to Regulated Utilities' financial position, results of operations and cash flows. Regulated Utilities cannot predict the outcome of these proceedings. See Note 4 to the Condensed Consolidated Financial Statements, “Regulatory Matters,” for additional information.
In AprilJune 2015, the Florida Legislature passedgovernor signed legislation which is pending approval by the governor, to allow utilities to issuepetition for a financing order for securitization bonds as an option to recover the costs of certain retired nuclear generation facilities. If enacted, this legislation would apply toassets. On July 27, 2015, Duke Energy Florida’s retiredFlorida petitioned the FPSC for a financing order to finance the Crystal River Unit 3 nuclear station.Regulatory asset with low-cost securities. If the FPSC issues an acceptable financing order and Duke Energy Florida issues the bonds, securitization would replace the base rate recovery methodology established in the 2013 Agreement described above, and would result in a lower rate impact to customers. Securitization of the costs of the retired Crystal River Unit 3 nuclear stationNuclear Plant would result in an initial acceleration of cash, followed by a reduction to Regulated Utilities’ future results of operations and ongoing cash flows as it would no longer earn an equity return on these costs. Under thea previous settlement agreement with the FPSC, the allowed return on equity for Crystal River Unit 3 is limited to 70 percent of the approved return on equity, which is currently 10.5 percent. The FPSC is expected to hold a hearing on both the Crystal River Unit 3 Regulatory asset filing and the securitization filing in October 2015.

International Energy’s results were impacted by the absence of a prior year merger step-up tax benefit in Chile and unfavorable hydrology in Brazil. The following is a detailed discussion of the variance drivers by line item.
Operating Revenues.The variance was driven primarily by:
a $36 million decrease in Brazil due to unfavorable exchange rates, partially offset by higher average contract prices; and
a $29 million decrease in Central America due to lower average prices as a result of increased competition.
Operating Expenses.The variance was driven primarily by:
a $17 million decrease in Central America due to lower fuel costs and consumption partially offset by higher purchased power; and
a $10 million decrease in Peru due to lower hydrocarbon royalty and purchased power costs.
Other Income and Expenses, net.The variance is primarily due to lower interest income due to a lower cash balance held in Brazil and lower equity earnings in NMC as a result of lower average MTBE and methanol prices, partially offset by lower butane costs.
Income Tax Expense. The effective tax rate for the three months ended June 30, 2015 and 2014 was 15.9 percent and (4.1) percent, respectively. The increase in the effective tax rate is primarily due to a tax benefit recorded in second quarter 2014 as a result of the merger of two Chilean subsidiaries.

Other Income and Expenses, net. The variance is primarily due to a net remeasurement loss in Latin America, lower interest income due to a lower cash balance held in Brazil, and lower equity earnings in NMC as a result of lower average MTBE and methanol prices, partially offset by lower butane costs.

100


PART I

Income Tax Expense. The variance in tax expense is primarily due to a decrease in pretax income. The effective tax rate for threesix months ended March 31,June 30, 2015 and 2014 was 35.625.0 percent and 27.713.9 percent, respectively. The increase in the effective tax rate is primarily due to unfavorable Brazilian exchange rates.a tax benefit recorded in second quarter 2014 as a result of the merger of two Chilean subsidiaries.
Matters Impacting Future International Energy Results
International Energy's operations include conventional hydroelectric power generation facilities located in Brazil where water reservoirs are currently at abnormally low levels due to a lack of rainfall. Weather and economic conditions within Brazil have resulted in higher energy prices and a reduction in demand. In addition, International Energy’s equity earnings from NMC reflect sales of methanol and MTBE, which generate margins that are directionally correlated with crude oil prices. International Energy's earnings and future cash flows could be adversely impacted by either a sustained period of low reservoir levels, especially if the government of Brazil were to implement rationing or some other mandatory conservation program, changes to power prices that further impact demand, further decline of economic conditions within Brazil or a significant decrease in crude oil prices.

Matters Impacting Future Other Results
Duke Energy Ohio’s retired Beckjord generating stationStation (Beckjord) became an asset of Other after the sale of the nonregulated Midwest Generation business in the second quarter of 2015. Beckjord, a nonregulated facility retired during 2014, is not subject to the recently enacted Environmental Protection Agency (EPA) rule related to the disposal of coal combustion residuals (CCR) from electric utilities. However, if costs are incurred as a result of environmental regulations or to mitigate risk associated with the storage of coal ash, the costs could have an adverse impact on Other's financial position, results of operations and cash flows.

If the FPSC issues an acceptable financing order and Duke Energy Florida issues the bonds, securitization would replace the base rate recovery methodology established in the 2013 Agreement described above, and would result in a lower rate impact to customers. Securitization of the costs of the retired Crystal River Unit 3 nuclear stationNuclear Plant would result in an initial acceleration of cash, followed by a reduction to Progress Energy's future results of operations and ongoing cash flows as it would no longer earn an equity return on these costs. Under the currenta previous settlement agreement with the FPSC, the allowed return on equity for Crystal River Unit 3 is limited to 70 percent of the approved rate ofreturn on equity, which is currently 10.5 percent.

Operating Revenues.The variance was driven primarily by:
A $51a $93 million decrease in fuel revenues (including emission allowances) primarily due to a decrease in fuel rates as a result of lower fuel and purchased power costs, and lower sales volumes. Fuel revenues represent sales to retail and wholesale customers;
a $14 million decrease in rate riders primarily due to lower energy efficiency revenues; and
a $6 million decrease in weather-normal sales volumes to retail customers (net of fuel revenue) reflecting decreased demand.
Operating Expenses.The variance was driven primarily by:
A $45a $97 million decrease in fuel used in electric generation and purchased power primarily due to lower sales volumes and lower fuel prices; and
A $24a $26 million decrease in property and other taxes, primarily as a result of lower sales and use tax.
Partially offset by:
A $15a $36 million increase in operation and maintenance expense primarily due to timing and increased scope of outage work at generation plants.plants; and
a $6 million increase in depreciation and amortization expense primarily due to higher depreciation as a result of additional plant in service.
Income Tax Expense.The variance was primarily due to a decrease in pretax income. The effective tax rate for the threesix months ended March 31,June 30, 2015 and 2014 was 36.636.5 percent and 36.8 percent, respectively.
Matters Impacting Future Results
Duke Energy Indiana is evaluating converting Wabash River Unit 6 to a natural gas-fired unit or retiring the unit earlier than its current estimated useful life. If Duke Energy Indiana elects early retirement of the unit, recovery of remaining book values and associated carrying costs totaling approximately $40 million could be subject to future regulatory approvals and therefore cannot be assured.
In 2015, the Indiana Utility Regulatory Commission (IURC)IURC is examining intervenors' allegations regarding the Edwardsport IGCC in-service date for ratemaking purposes, operational performance of the plant, the level of operating costs and financing charges associated with construction delays. The outcome of these proceedings could have an adverse impact to Regulated Utilities'Duke Energy Indiana's financial position, results of operations and cash flows. Regulated UtilitiesDuke Energy Indiana cannot predict the outcome of these proceedings. See Note 4 to the Condensed Consolidated Financial Statements, “Regulatory Matters,” for additional information.

PART I

On April 17, 2015, the EPA published in the Federal Register a rule to regulate the disposal of CCR from electric utilities as solid waste. Duke Energy Indiana has interpreted the rule to identify the coal ash basin sites impacted and has assessed the amounts of coal ash subject to the rule and a method of compliance. Duke Energy Indiana's interpretation of the requirements of the CCR rule, which becomes effective in October 2015, is subject to potential legal challenges and further regulatory approvals, which could result in additional ash basin closure requirements, higher costs of compliance and greater asset retirement obligations. An order from regulatory authorities disallowing recovery of costs related to closure of ash basins could have an adverse impact to the Duke Energy Indiana's financial position, results of operations and cash flows. See Note 5 to the Condensed Consolidated Financial Statements, “Commitments and Contingencies,” for additional information.

PART I

LIQUIDITY AND CAPITAL RESOURCES
Sources and Uses of Cash
Duke Energy relies primarily upon cash flows from operations, debt issuances and its existing cash and cash equivalents to fund its domestic liquidity and capital requirements. Duke Energy’s capital requirements arise primarily from capital and investment expenditures, repaying long-term debt and paying dividends to shareholders. See Duke Energy’s Annual Report on Form 10-K for the year ended December 31, 2014 for a summary of primary sources and uses of cash for 2015-2017 and a more detailed discussion of each.
The Subsidiary Registrants generally maintain minimal cash balances and use short-term borrowings to meet their working capital needs and other cash requirements. The Subsidiary Registrants, excluding Progress Energy (Parent), support their short-term borrowing needs through participation with Duke Energy and certain of its other subsidiaries in a money pool arrangement. The companies with short-term funds may provide short-term loans to affiliates participating under this arrangement.
Duke Energy and the Subsidiary Registrants, excluding Progress Energy (Parent), may also use short-term debt, including commercial paper and the money pool, as a bridge to long-term debt financings. The levels of borrowing may vary significantly over the course of the year due to the timing of long-term debt financings and the impact of fluctuations in cash flows from operations. Duke Energy’s current liabilities may at times exceed current assets resulting from the use of short-term debt as a funding source to meet scheduled maturities of long-term debt, as well as cash needs, which can fluctuate due to the seasonality of its business.
Credit Facility and Registration Statements
Master Credit Facility Summary
Duke Energy has a Master Credit Facility with a capacity of $7.5 billion through January 2020. The Duke Energy Registrants, excluding Progress Energy (Parent), have borrowing capacity under the Master Credit Facility up to a specified sublimit for each borrower. Duke Energy has the unilateral ability at any time to increase or decrease the borrowing sublimits of each borrower, subject to a maximum sublimit for each borrower. The amount available under the Master Credit Facility has been reduced to backstop issuances of commercial paper, certain letters of credit, and variable-rate demand tax-exempt bonds that may be put to the Duke Energy Registrants at the option of the holder.holder and as security to meet obligations under the Plea Agreements. The table below includes the current borrowing sublimits and available capacity under the Master Credit Facility.

(b)Duke Energy issued $475 million of commercial paper and loaned the proceeds through the money pool to Duke Energy Carolinas, Duke Energy Ohio and Duke Energy Indiana. The balances are classified as Long-Term Debt Payable to Affiliated Companies in the Condensed Consolidated Balance Sheets.
On April 2, 2015, Duke Energy completed the sale of the nonregulated Midwest generation business to Dynegy for approximately $2.8 billion in cash. Duke Energy used the proceeds to pay down its outstanding commercial paper by approximately $1.3 billion and initiated an agreement to repurchase $1.5 billion of Duke Energy common stock under the ASR. See Notes 2 and 13 to the Condensed Consolidated Financial Statements, “Acquisitions and Dispositions” and "Common Stock", respectively, for additional information.
On February 20, 2015, Duke Energy Carolinas, Duke Energy Progress and Duke Energy Business Services LLC (DEBS), a wholly owned subsidiary of Duke Energy, each entered into Plea Agreements in connection with the investigation initiated by the USDOJ. Duke Energy Carolinas and Duke Energy Progress are required to each maintain $250 million of available capacity under the Master Credit Facility as security to meet their obligations under the Plea Agreements, in addition to certain other conditions. The Plea Agreements are subject to court approval. See Note 5 to the Condensed Consolidated Financial Statements, “Commitments and Contingencies,” for additional information.
(c)On May 14, 2015, the United States District Court for the Eastern District of North Carolina approved the separate Plea Agreements entered into by Duke Energy Carolinas, Duke Energy Progress and Duke Energy Business Services LLC (DEBS), a wholly owned subsidiary of Duke Energy in connection with the investigation initiated by the USDOJ. Duke Energy Carolinas and Duke Energy Progress are required to each maintain $250 million of available capacity under the Master Credit Facility as security to meet their obligations under the Plea Agreements, in addition to certain other conditions. See Note 5 to the Condensed Consolidated Financial Statements, “Commitments and Contingencies,” for additional information.
PremierNotes
Duke Energy has an effective Form S-3 with the Securities and Exchange Commission (SEC) to sell up to $3 billion of variable denomination floating-rate demand notes, called PremierNotes. The Form S-3 states that no more than $1.5 billion of the notes will be outstanding at any particular time. The notes are offered on a continuous basis and bear interest at a floating rate per annum determined by the Duke Energy PremierNotes Committee, or its designee, on a weekly basis. The interest rate payable on notes held by an investor may vary based on the principal amount of the investment. The notes have no stated maturity date, are non-transferable and may be redeemed in whole or in part by Duke Energy or at the investor’s option at any time. The balance as of March 31,June 30, 2015 and December 31, 2014 was $1,010$1,048 million and $968 million, respectively. The notes are short-term debt obligations of Duke Energy and are classified within Notes payable and commercial paper on Duke Energy’s Condensed Consolidated Balance Sheets.

CASH FLOWS FROM OPERATING ACTIVITIES
The relatively stable operating cash flows of Regulated Utilities compose a substantial portion of Duke Energy’s cash flows from operations. Regulated Utilities’ cash flows from operations are primarily driven by sales of electricity and natural gas and costs of operations. Weather conditions, commodity price fluctuations and unanticipated expenses, including unplanned plant outages, storms and storms,legal costs and related settlements, can affect the timing and level of cash flows from operations.
Cash flows from operations are subject to a number of other factors, including but not limited to regulatory constraints, economic trends and market volatility (see “Item 1A. Risk Factors,” in the Duke Energy Registrants’ Annual Report on Form 10-K for the year ended December 31, 2014 for additional information).
At March 31,June 30, 2015, Duke Energy had cash and cash equivalents and short-term investments of $2.8 billion,$960 million, of which $1.7 billion$664 million is held by entities domiciled in foreign jurisdictions. In December 2014, Duke Energy declared a taxable dividend of historical foreign earnings in the form of notes payable that will result in the repatriation ofto repatriate approximately $2.7 billion of cash held and expected to be generated by International Energy over a period of up to eight years. Approximately $1.2-$1.4In June 2015, approximately $1.2 billion was remitted. The remaining amount will be remitted in 2015, with the remaining amount remitted by 2022. The remittances will principally be used to support Duke Energy's dividend and growth in the domestic business. As a result of the decision to repatriate all cumulative historic undistributed foreign earnings, during the fourth quarter of 2014, Duke Energy recorded U.S. income tax expense of approximately $373 million. Duke Energy’s intention is to indefinitely reinvest prospective undistributed earnings generated by Duke Energy's foreign subsidiaries. As a result, no U.S. tax is recorded on such prospective earnings. Duke Energy would be required to accrue taxes on these foreign earnings if they were to be repatriated. As of March 31,June 30, 2015, the amount of unrecognized deferred tax liability related to undistributed earnings was not material. See Note 17 to the Condensed Consolidated Financial Statements, “Income Taxes,” for additional information.
Restrictive Debt Covenants
The Duke Energy Registrants’ debt and credit agreements contain various financial and other covenants. The Master Credit Facility contains a covenant requiring the debt-to-total capitalization ratio to not exceed 65 percent for each borrower. Failure to meet those covenants beyond applicable grace periods could result in accelerated due dates and/or termination of the agreements. As of March 31,June 30, 2015, each of the Duke Energy Registrants was in compliance with all covenants related to their significant debt agreements. 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 significant debt or credit agreements contain material adverse change clauses.
Credit Ratings
Credit ratings are intended to provide credit lenders a framework for comparing the credit quality of securities and are not a recommendation to buy, sell or hold. The Duke Energy Registrants’ credit ratings are dependent on the rating agencies’ assessments of their ability to meet their debt principal and interest obligations when they come due. If, as a result of market conditions or other factors, the Duke Energy Registrants are unable to maintain current balance sheet strength, or if earnings and cash flow outlook materially deteriorate, credit ratings could be negatively impacted.
The Duke Energy Registrants each hold credit ratings by Fitch Ratings, Inc. (Fitch), Moody’s Investors Service, Inc. (Moody’s) and Standard & Poor’s Rating Services (S&P). OnIn April 2, 2015, S&P upgraded Duke Energy's and Progress Energy's corporate credit rating to A- from BBB+ and their unsecured credit rating to BBB+ from BBB. The unsecured credit ratings of the other Subsidiary Registrants were upgraded to A- from
BBB+. In June 2015, Moody's placed Duke Energy, Progress Energy and Duke Energy Progress on negative outlook from stable. In June 2015, Fitch upgraded Duke Energy Carolinas' issuer default rating to A from A-, its unsecured credit rating to A+ from A and its secured credit rating to AA- from A+. Fitch also placed Duke Energy Indiana on positive outlook from stable.

OTHER MATTERS
Environmental Regulations
Duke Energy is subject to international, federal, state and local regulations regarding air and water quality, hazardous and solid waste disposal, and other environmental matters. The Subsidiary Registrants are 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 and result in new obligations of the Duke Energy Registrants.
The following sections outline various proposed and recently enacted regulations that may impact the Duke Energy Registrants. The Duke Energy Registrants also expect to incur increased fuel, purchased power, operation and maintenance, and other costs for replacement generation for potential coal-fired power plant retirements as a result of these proposed and final regulations. The actual compliance costs may be materially different from these estimates based on the timing and requirements of the final EPA regulations. Refer to Note 4 to the Condensed Consolidated Financial Statements, "Regulatory Matters," for further information regarding potential plant retirements and regulatory filings related to the Duke Energy Registrants.
Coal Combustion Residuals
On April 17, 2015, the EPA published in the Federal RegistryRegister a rule to regulate the disposal of CCR from electric utilities as solid waste. The federal regulation, which becomes effective six months after publication, classifies CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act.Act and allows for beneficial use of CCRs with some restrictions. The regulation applies to all new and existing landfills, new and existing surface impoundments, structural fills and CCR piles. The rule establishes requirements regarding landfill design, structural integrity design and assessment criteria for surface impoundments, groundwater monitoring and protection procedures and other operational and reporting procedures to ensure the safe disposal and management of CCR. In addition to the requirements of the federal CCR regulation, CCR landfills and surface impoundments will continue to be independently regulated by most states. Duke Energy records an asset retirement obligation (ARO) when it has a legal obligation to incur retirement costs associated with the retirement of a long-lived asset and the obligation can be reasonably estimated.Carolinas, Progress Energy, Duke Energy Registrants impacted by the rule will record additionalProgress, Duke Energy Ohio and Duke Energy Indiana recorded asset retirement obligation amounts induring the second quarter of 2015. Cost recovery for future expenditures will be pursued through the normal ratemaking process with federal and state utility commissions, which permit recovery of necessary and prudently incurred costs associated with Duke Energy’s regulated operations. For more information, see Note 57 to the Condensed Consolidated Financial Statements, "Commitments and Contingencies."Asset Retirement Obligations." The following table provides estimated cost ranges for compliance with the CCR regulation incremental to existing state statutes.

PART I

Duke Energy Ohio's nonregulated Beckjord Station, a facility retired during 2014, is not subject to the recently enacted EPA rule related to the disposal of CCR from electric utilities. However, if costs are incurred as a result of environmental regulations or to mitigate risk associated with coal ash at the facility, the costs could have an adverse impact to Duke Energy Ohio's financial position, results of operations and cash flows.
Coal Ash Management Act of 2014
On September 20, 2014, the North Carolina Coal Ash Management Act of 2014 (Coal Ash Act) became law.law and was amended on June 24, 2015 by the Mountain Energy Act of 2015. The Coal Ash Act, as amended, (i) establishes a Coal Ash Management Commission (Coal Ash Commission) to oversee handling of coal ash within the state; (ii) prohibits construction of new and expansion of existing ash impoundments and use of existing impoundments at retired facilities; (iii) requires closure of ash impoundments at Duke Energy Progress' Asheville and Sutton stationsPlant and Duke Energy Carolinas' Riverbend and Dan River stations no later than August 1, 2019;2019 and Duke Energy Progress' Asheville Plant no later than August 1, 2022; (iv) requires dry disposal of fly ash at active plants, excluding the Asheville Plant, not retired by December 31, 2018; (v) requires dry disposal of bottom ash at active plants, excluding the Asheville Plant, by December 31, 2019, or retirement of active plants; (vi) requires all remaining ash impoundments in North Carolina to be categorized as high-risk, intermediate-risk or low-risk no later than December 31, 2015 by the North Carolina Department of Environment and Natural Resources (DENR) with the method of closure and timing to be based upon the assigned risk, with closure no later than December 31, 2029; (vii) establishes requirements to deal with groundwater and surface water impacts from impoundments; and (viii) enhances the level of regulation for structural fills utilizing coal ash. The Coal Ash Act includes a variance procedure for compliance deadlines and modification of requirements regarding structural fills and compliance boundaries. Provisions of the Coal Ash Act prohibit cost recovery in customer rates for unlawful discharge of ash basin waters occurring after January 1, 2014. The Coal Ash Act leaves the decision on cost recovery determinations related to closure of CCR surface impoundments (ash basins or impoundments) to the normal ratemaking processes before utility regulatory commissions. Duke Energy has and will periodically submit to DENR site-specific coal ash impoundment closure plans or excavation plans in advance of closure plans. These plans and all associated permits must be approved by DENR before any excavation or closure work can begin.
In September 2014, Duke Energy Carolinas executed a consent agreement with the South Carolina Department of Health and Environmental Control (SCDHEC) requiring the excavation of an inactive ash basin and ash fill area at the W.S. Lee Steam Station. As part of this agreement, in December 2014, Duke Energy Carolinas filed an ash removal plan and schedule with SCDHEC. In April 2015, the federal CCR rules were published and Duke Energy Carolinas subsequently executed an agreement with the conservation groups Upstate Forever and Save Our Saluda requiring Duke Energy Carolinas to remediate all active and inactive ash storage areas at the W.S. Lee Steam Station. Coal-fired generation at W.S. Lee ceased in 2014 and unit 3 is being converted to natural gas. In July 2015, Duke Energy Progress executed a consent agreement with the SCDHEC requiring the excavation of an inactive ash fill area at the Robinson Plant within eight years. The Robinson and Lee sites are required to be closed pursuant to the recently issued CCR rule and the provisions of these consent agreements are consistent with the federal CCR closure requirements.
For further information, refer to Note 5 of the Condensed Consolidated Financial Statements, “Commitments and Contingencies.”
Mercury and Air Toxics Standards
The final Mercury and Air Toxics Standards (MATS) rule was issued on February 16, 2012. The rule establishes emission limits for hazardous air pollutants from new and existing coal-fired and oil-fired steam electric generating units. The rule requires sources to comply with emission limits by April 16, 2015. Under the Clean Air Act (CAA), permitting authorities have the discretion to grant up to a one-year compliance extension, on a case-by-case basis, to sources that are unable to complete the installation of emission controls before the compliance deadline. The Duke Energy Registrants have requested and received compliance extensions for a number of its plants and have met theplants. The rule requirements apply where a compliance extension was not received. Duke Energy Registrants are on track to meet the requirements. Strategies to achieve compliance include installation of new air emission control equipment, development of monitoring processes, fuel switching and acceleration of retirement for some coal-fired electric-generation units. For additional information, refer to Note 4 to the Condensed Consolidated Financial Statements, "Regulatory“Regulatory Matters," regarding potential plant retirements.
In April 2014, several petitions for review of the final rule were denied by the U.S. Court of Appeals for the District of Columbia (D.C. Circuit Court). On November 25, 2014, the Supreme Court granted a petition for review based on the issue of whether the EPA unreasonably refused to consider costs in determining whether it is appropriate and necessary to regulate hazardous air pollutants from coal-fired and oil-fired steam electric generating units. Oral arguments were held on March 25, 2015. The Duke Energy Registrants cannot predict the outcome ofIn June 2015, the Supreme Court review ofreversed the D.C. Circuit Court's decision and remanded the case to the D.C. Circuit Court decision.for further proceedings, finding that the EPA erred in refusing to consider costs when deciding whether it was appropriate and necessary to regulate emissions of hazardous air pollutants from steam electric generating units. Pending action by the D.C. Circuit Court, the rule remains in effect. Duke Energy cannot predict the results of these proceedings.
Clean Water Act 316(b)
The EPA published the final 316(b) cooling water intake structure rule on August 15, 2014, with an effective date of October 14, 2014. The rule applies to 2726 of the electric generating facilities the Duke Energy Registrants own and operate depending on unit retirement dates, excluding stations included in the Disposal Group.operate. The rule allows for several options for demonstratingto demonstrate compliance and provides flexibility to the state environmental permitting agencies to make determinations on controls, if any, that will be required for cooling water intake structures. Any required intake structure modifications and/or retrofits are expected to be installed in the 2019 to 2022 time frame. Petitions challenging the rule have been filed by several groups. It is unknown at this time when the courts will rule on the petitions.
Steam Electric Effluent Limitations Guidelines
On June 7, 2013, the EPA proposed Steam Electric Effluent Limitations Guidelines (ELG). The EPA is under a revised court order to finalize the rule by September 30, 2015. The EPA has proposed eight options for the rule, which vary in stringency and cost. The proposed regulation applies to seven waste streams, including wastewater from air pollution control equipment and ash transport water. Most, if not all, of the steam electric generating facilities the Duke Energy Registrants own are likely affected sources. Requirements to comply with the final rule may begin as early as late 2018 for some facilities.

PART I

Estimated Cost and Impacts of Rulemakings
The ultimate compliance requirements for currently proposed environmental regulations will not be known until all the rules have been finalized. The Duke Energy Registrants also expect to incur increased fuel, purchased power, operation and maintenance, and other expenses, in addition to costs for replacement generation for potential coal-fired power plant retirements as a result of these regulations. The actual compliance costs incurred may be materially different from these estimates based on the timing and requirements of the final regulations. The Duke Energy Registrants intend to seek rate recovery of appropriate amountsnecessary and prudently incurred costs associated with regulated operations in complying with these regulations. Refer to Note 4 toof the Condensed Consolidated Financial Statements, “Regulatory Matters," for further information regarding potential plant retirements and regulatory filings related to the Duke Energy Registrants.

Cross-State Air Pollution Rule
On August 8, 2011, the final Cross-State Air Pollution Rule (CSAPR) was published in the Federal Register. The CSAPR established state-level annual sulfur dioxide (SO2)2) budgets and annual and seasonal nitrogen oxide (NOx) budgets that were to take effect on January 1, 2012.
On August 21, 2012, the D.C. Circuit Court vacated the CSAPR. The court also directed the EPA to continue administering the Clean Air Interstate Rule (CAIR), which required additional reductions in SO2 and NOx emissions beginning in 2015. On April 29, 2014, the U.S. Supreme Court (Supreme Court) reversed the D.C. Circuit Court’s decision, finding that with CSAPR the EPA reasonably interpreted the good neighbor provision of the CAA. The case was remanded to the D.C. Circuit Court for further proceedings consistent with the Supreme Court’s opinion. On October 23, 2014, the D.C. Circuit Court lifted the CSAPR stay, which allowed Phase 1 of the rule to take effect on January 1, 2015, terminating the CAIR. Where the CSAPR requirements are constraining, actions to meet the requirements could include purchasing emission allowances, power purchases, curtailing generation and utilizing low sulfur fuel. The CSAPR will not result in Duke Energy Registrants adding new emission controls.
Additional legal challenges to the CSAPR filed in 2012, not addressed by the D.C. Circuit Court decision to vacate the CSAPR, are still ongoing. Oral arguments were held February 25, 2015. The Duke Energy Registrants cannot predict the outcome of these proceedings or how the requirements of the CSAPR may be impacted going forward.
Carbon DioxidePollution Standards for New, Source Performance StandardsModified and Reconstructed Power Plants
On January 8, 2014,August 3, 2015, the EPA proposed a rule to establishissued the final rules establishing carbon dioxide (CO2) emissions standardslimits for new, pulverized coal, IGCC,modified, and reconstructed power plants. A new source is any fossil fuel-fired power plant that commenced construction on or after January 8, 2014. The 1,400 lb /MWh CO2 emission limit EPA established for new coal-fired power plants reflects the application of carbon capture technology at a 20 percent capture rate. The 1,000 lb/MWh CO2 emission limit the EPA established for new stationary combustion turbines is based on natural gas combined cycle and simple cycle electric generating units commencing construction on or after that date. Basedtechnology.
The emission standard the EPA established for modified power plants would be a unit-specific limit based on the proposal, future coal and IGCC units will be required to employ carbon capture and storage technology to meet the proposed standard.
In January 2015,source’s historical annual performance.  The emission standards the EPA announced that it would finalize the ruleestablished for newreconstructed coal-fired power plants in the summer of 2015. ranges from 1,800 to 2,000 lb CO2/MWh.
The Duke Energy Registrants are evaluating the impacts of the final rule, but do not expect a material impact on their future results of operations or cash flows based onbelieve the EPA’s proposal. The final rule, however, couldimpacts will be significantly different from the proposal.material.
CO2 Existing Source Performance Standards and Standards for Reconstructed and Modified UnitsClean Power Plan
On June 18, 2014,August 3, 2015, the EPA’s proposedEPA issued the final Clean Power Plan (CPP) for regulating CO2 emissions from existing fossil fuel-fired electric generating units (EGUs) was published in the Federal Register. On the same date the EPA proposed carbon pollution standards for reconstructed. The CPP establishes state-level CO2 emission rates and modified EGUs. The comment period ended October 16, 2014 for the reconstructed and modified proposal and December 1, 2014 for the CPP. Duke Energy submitted comments on both proposals. In January 2015 the EPA announcedmass cap goals that it would finalize both proposals in the summer of 2015.
Once the CPP is finalized, states will beapply to fossil fuel-fired generation. States are required to develop plansand submit a final compliance plan, or an initial plan with an extension request, to the EPA by September 6, 2016. States that receive an extension must submit a final completed plan to the EPA by September 6, 2018. The EPA will take a year to review state plans. Once approved, states must implement its requirements.their plan to ensure power plants achieve the interim CO2 emissions performance goals over the period of 2022 to 2029 and the final CO2 goals in 2030 and beyond. The CPP willdoes not directly impose any regulatory requirements on the Duke Energy Registrants. State implementation plans will include the regulatory requirements that will apply to Duke Energy Registrants. Based on the EPA’s June 18, 2014 proposal, states will have from one to three years after the CPP is finalized to submit a plan for EPA’s review. In January 2015 the EPA announced that it would also propose a federal implementation plan for public comment in the summer of 2015. A federal plan would be EPA’s plan for meeting the requirements of the CPP and could take the place of a state plan if a state either fails to submit a plan or submits a plan that is not approved by the EPA.
The EPA has proposed to phase CO2 emission reductions in over the period 2020 to 2030. The final requirements of the CPP, however, including the implementation schedule, are uncertain and could be significantly different from the proposal. In addition, it will be several years before the requirements of the subsequent state plans are known. Also unknown at this time are the requirements of any federal plan that might be imposed on states in which the Duke Energy Registrants operate should a state fail to submit a plan or have their plan disapproved by the EPA.Registrants. The Duke Energy Registrants are therefore unable to predictdetermine how the outcome of this rulemaking, or how it mightfinal CPP rule will impact them until state plans are developed and approved by the EPA , but the impact could be significant.
The EPA also released a proposed federal plan for public comment. A federal plan would be applied to states that fail to submit a plan to EPA or where a state plan is not approved by the EPA. Comment on the proposed federal plan are due 90 days after it is published in the Federal Register.
