COMMITMENTS AND CONTINGENCIES

ENVIRONMENTAL

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, imposing new obligations on the Duke Energy Registrants.

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 table contains 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.

Ash Basins

On February 2, 2014, a break in a 48-inch 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 48-inch stormwater pipe, stopping the release of materials into the river. On February 21, 2014, a permanent plug was installed in a 36-inch stormwater pipe beneath the ash basin. 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 during the incident. Duke Energy Carolinas incurred approximately $20 million of repairs and remediation expense related to this incident during the six months ended June 30, 2014. These amounts are recorded in Operations, maintenance and other on the Condensed Consolidated Statements of Operations and Comprehensive Income. Duke Energy Carolinas will not seek recovery of these costs from ratepayers. In July, Duke Energy completed remediation work identified by EPA. Other costs related to the Dan River release and the overall ash management plan, including regulatory directives, natural resources damages, pending litigation, future claims or litigation, long-term environmental impact costs, long-term operational changes, and costs associated with new laws and regulations, cannot be reasonably estimated at this time. However, the total costs to be incurred for any potential additional remediation relating to the Dan River ash release are not expected to be material.

Duke Energy has engaged third-party engineering experts to complete an independent engineering review of all its ash basins. Initial field work has been completed. Findings and recommendations are being reviewed with management and repair actions are being taken to address the findings. Duke Energy is also preparing a comprehensive, longer-term ash basin strategy, which will involve a site by site analysis of applicable laws, regulations, site characteristics, and engineering feasibility. We expect this work to be completed by the end of the year, with detailed engineering to follow. Each site is unique, and site-specific engineering will help determine the most appropriate closure method for that site.

On March 12, 2014, Duke Energy issued a letter to the governor of the state of North Carolina and the secretary of the North Carolina Department of Environment and Natural Resources (DENR) outlining recommendations for near-term and longer-term action at its ash basins in North Carolina. Implementing the near-term recommendations and longer-term plans depends on receipt of various state and federal permits and determinations that these actions are prudent, cost-effective and environmentally sound. The near-term actions outlined in the letter include moving ash from basins at three coal plants to lined fill solutions, converting the remaining coal units to dry fly ash handling or retiring the units, and minimizing potential risk of an incident similar to Dan River by removing water from ash basins at all retired North Carolina coal plants.

On April 22, 2014, a representative of Duke Energy appeared before the Environmental Review Commission of the North Carolina General Assembly and outlined cost estimates for a range of ash handling and ash basin closure options. The table below summarizes estimated costs of various potential approaches to ash management for North Carolina ash basins. These amounts represent a rough order of magnitude and are not detailed engineering grade estimates. The estimates assume coal ash will retain a non-hazardous designation by the EPA and exclude financing costs. Any ultimate activities and resultant costs will be dependent upon state and federal environmental requirements.

(in billions)	Range
Baseline assumptions(a)	$	2.0	-	$	2.5
Estimated additional costs related to full excavation(b)	4.0		-	5.5
Estimated additional costs related to all-dry systems(c)	1.0		-	2.0
Total range of costs(d)	$	2.0	-	$	10.0

(a) Assumes (i) hybrid cap in place closure for ash basins at ten coal plants, (ii) excavation and relocation of ash to lined structural fills or landfills for the retired Dan River, Riverbend and Sutton coal plants, (iii) dry fly ash conversion at the Asheville units and Cliffside Unit 5, (iv) continued structural fill disposal for the Asheville coal plant, and (v) dry bottom ash handling conversions and fly ash reliability improvements. Includes costs for actions noted in the March 12, 2014 letter to the governor of North Carolina and existing plans to close ash basins.

(b) Represents estimated additional costs to excavate and relocate ash to lined landfills for the ten plants under hybrid cap in place closure in the baseline assumptions.

(c) Represents estimated additional costs to convert all active coal plants to all-dry pneumatic bottom ash handling systems and thermally-driven evaporation of other process water.

(d) On average, the allocation of these estimates is approximately 65 percent to Duke Energy Carolinas and 35 percent to Duke Energy Progress. However, this allocation could vary significantly based on site-specific compliance actions.

The North Carolina Senate adopted a bill on June 25, 2014, which would (i) establish a Coal Ash Management Commission to oversee handling of coal ash within the state; (ii) prohibit construction of new and expansion of existing ash impoundments; (iii) require closure of ash impoundments at Asheville, Riverbend, Dan River and Sutton stations no later than August 1, 2019; (iv) require an evaluation and ranking of remaining ash impoundments in North Carolina with closure of all basins within no later than fifteen years, (v) establish requirements to deal with groundwater and surface water impacts from impoundments and (vi) enhance the level of regulation for structural fills utilizing coal ash. On July 3, 2014, the North Carolina House adopted its version of the bill with several differences including a variance procedure for compliance deadlines and modification of requirements regarding structural fills and compliance boundaries. Both proposed laws, as written, leave the decision on cost recovery determinations to the state utilities commissions after a moratorium ending no later than December 31, 2016. However, the proposed laws do not prohibit requests for regulatory deferral orders during the moratorium. The legislature appointed a conference committee to resolve differences in the two bills. However, the North Carolina General Assembly did not pass final legislation prior to adjourning its session in early August 2014. Coal ash legislation could be considered during a reconvened legislative session later in 2014.

Duke Energy records asset retirement obligations 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 has not recorded an asset retirement obligation related to these proposals as a legal obligation has not yet been incurred. As the necessary approvals are obtained to permit the work to proceed an asset retirement obligation could be recorded. Cost recovery for these expenditures will be pursued through the normal ratemaking process with state utility commissions, which permits the recovery of necessary and prudently incurred costs associated with Duke Energy's regulated operations. While Duke Energy cannot predict the outcome of these matters, it believes compliance costs will be within the range outlined in the above table. However, ultimate costs will be largely dependent upon compliance alternatives allowed to meet requirements of the legislation, once enacted.

LITIGATION

Duke Energy

Ash Basin Shareholder Derivative Litigation

Two shareholder derivative lawsuits have been filed relating to the release at Dan River and to the management of Duke Energy’s ash basins. The first lawsuit was filed on May 21, 2014, in Delaware Chancery Court by shareholders Edward Tansey and the Police Retirement System of St. Louis and names as defendants several current and former Duke Energy officers and directors together with all current directors of Duke Energy (collectively, the “Duke Energy Defendants”). The second lawsuit was filed against the Duke Energy Defendants on July 18, 2014, in Delaware Chancery Court by shareholder Robert Reese. Duke Energy is named as a nominal defendant in both lawsuits.

Both complaints allege the Duke Energy Defendants breached their fiduciary duties to the company by failing to adequately oversee Duke Energy’s ash basins since 2008 and that these breaches of fiduciary duty may have contributed to the incident at Dan River and continued thereafter. The Tansey complaint also asserts claims against the Duke Energy Defendants for corporate waste (relating to the money Duke Energy has 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 lawsuits seek both injunctive relief against Duke Energy and restitution from the Duke Energy Defendants.

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 Duke Energy 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.

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 eleven members of the Duke Energy Board of Directors who were also members of the pre-merger Duke Energy 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 CEO. The claims are purportedly brought on behalf of a class of all persons who purchased or otherwise acquired Duke Energy securities between June 11, 2012 and July 9, 2012. On July 26, 2013, the Magistrate Judge recommended the District Court Judge deny the defendants’ motion to dismiss. On October 2, 2013, the District Judge heard defendants’ objections to this recommendation. A decision is pending on the motion to dismiss. An attempt on May 14, 2014, to mediate the claims was unsuccessful.

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 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. On May 17, 2013, the judge granted the defendants' motion to stay the litigation until a decision is rendered on the motion to dismiss in the Nieman v. Duke Energy Corporation, et al. case in North Carolina.

On August 3, 2012, Duke Energy was served with a shareholder Derivative Complaint, which was transferred to the North Carolina Business Court (Krieger v. Johnson, et al.). The lawsuit names as defendants William D. Johnson and the Legacy Duke Energy Directors. Duke Energy is named as a nominal defendant. The lawsuit alleges claims for breach of fiduciary duty in granting excessive compensation to Mr. Johnson. On April 30, 2014, the North Carolina Business Court granted the Legacy Duke Energy Directors’ motion to dismiss the lawsuit.

It is not possible to estimate the maximum exposure of loss that may occur in connection with these lawsuits.

Price Reporting Cases

A total of five lawsuits were filed against Duke Energy affiliates and other energy companies and remain pending in a consolidated, single federal court proceeding in Nevada.

Each of these cases 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 the remaining five cases to which Duke Energy affiliates are a party. The U.S. Court of Appeals for the Ninth Circuit subsequently reversed the lower court’s decision. On July 1, 2014, the U.S. Supreme Court granted the defendants', including Duke Energy, petition for certiorari. The case will be heard during the next session of the court, which begins in October 2014.

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. No trial date has been set. 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.

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 to Duke Energy Carolinas and Duke Energy Progress related to alleged groundwater violations and Clean Water Act violations from coal ash basins at two of their coal-fired power plants in North Carolina. The North Carolina Department of Environment and Natural Resources (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. 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 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 Clean Water Act 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. Southern Environmental Law Center (SELC), on behalf of several environmental groups, has been permitted to intervene in these cases.

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.

Federal Citizens Suits

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. 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. 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.

On July 1, 2014, Duke Energy received 60-day notices of intent to file citizen suits from the SELC on behalf of many of the same environmental groups who intervened in the state enforcement litigation described above. The notices relate to alleged Clean Water Act violations at ash basins from Duke Energy Carolinas' Buck station and Duke Energy Progress' H.F. Lee and Cape Fear stations. 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.

Dan River 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 have received subpoenas issued by the United States Attorney for the Eastern District of North Carolina in connection with a criminal investigation related to the release and all fourteen 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.

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.

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 CAA. The government alleges the utilities violated the CAA by not obtaining permits for certain projects undertaken at certain coal plants or installing the best available emission controls for SO2, NOx and particulate matter. The complaints seek the installation of pollution control technology on various 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 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. The EPA claims 29 projects performed at 25 of Duke Energy Carolinas’ coal-fired units violate the NSR provisions. Duke Energy Carolinas asserts the projects were routine or not projected to increase emissions. The parties filed a stipulation in which the United States dismissed with prejudice 16 claims. In exchange, Duke Energy Carolinas dismissed certain affirmative defenses. The parties filed opposing motions for summary judgment on the remaining claims. In November 2013, the Court denied Duke Energy’s motion for summary judgment. On March 17, 2014, the court similarly denied plaintiffs’ motion for summary judgment, except to confirm that the baseline for measuring an emissions increase at trial will be the two-year period immediately preceding each project. Duke Energy requested leave to file another motion for summary judgment on alternative grounds. That motion for leave remains pending. The 13 remaining claims involve 13 different generating units, 11 of which have already been retired.

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, 2014, there were 90 asserted claims for non-malignant cases with the cumulative relief sought of up to $19 million, and 35 asserted claims for malignant cases with the cumulative relief sought of up to $12 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 $600 million at June 30, 2014 and $616 million at December 31, 2013. 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 Carolinas has third-party insurance to cover certain losses related to asbestos-related injuries and damages above an aggregate self-insured retention of $476 million. Duke Energy Carolinas’ cumulative payments began to exceed the self-insurance retention in 2008. Future payments up to the policy limit will be reimbursed by the third-party insurance carrier. The insurance policy limit for potential future insurance recoveries indemnification and medical cost claim payments is $897 million in excess of the self-insured retention. Receivables for insurance recoveries were $649 million at both June 30, 2014 and December 31, 2013. These amounts are classified in Other within Investments and Other Assets and Receivables on the Condensed Consolidated Balance Sheets. Duke Energy Carolinas is not aware of any uncertainties regarding the legal sufficiency of insurance claims. Duke Energy Carolinas believes the insurance recovery asset is probable of recovery as the insurance carrier continues to have a strong financial strength rating.

Progress Energy

Synthetic Fuels Matters

Progress Energy and a number of its subsidiaries and affiliates are defendants in lawsuits arising out of a 1999 Asset Purchase Agreement. Parties to the Asset Purchase Agreement include U.S. Global, LLC (Global) and affiliates of Progress Energy.

In a case filed in the Circuit Court for Broward County, Florida, in March 2003 (the Florida Global Case), Global requested an unspecified amount of compensatory damages, as well as declaratory relief. In November 2009, the court ruled in favor of Global. In December 2009, Progress Energy made a $154 million payment, which represented payment of the total judgment, including prejudgment interest, and a required premium equivalent to two years of interest, to the Broward County Clerk of Court bond account. Progress Energy continued to accrue interest related to this judgment.

On October 3, 2012, the Florida Fourth District Court of Appeals reversed the lower court ruling. The court held that Global was entitled to approximately $90 million of the amount paid into the registry of the court. Progress Energy was entitled to a refund of the remainder of the funds. Progress Energy received cash and recorded a $63 million pretax gain for the refund in December 2012. The gain was recorded in Income from Discontinued Operations, net of tax in the Condensed Consolidated Statements of Operations and Comprehensive Income.

On May 9, 2013, Global filed a Seventh Amended Complaint asserting a single count for breach of the Asset Purchase Agreement and seeking specific performance. The parties reached a settlement in this matter in May 2014, and the case has been dismissed. The amount of the settlement did not have a material effect on the results of operations, cash flows or financial position of Progress Energy. As a result of the settlement of the Florida Global Case, a second suit filed in the Superior Court for Wake County, North Carolina, Progress Synfuel Holdings, Inc. et al. v. U.S. Global, LLC, has been dismissed.

Duke Energy Progress and Duke Energy Florida

Spent Nuclear Fuel Matters

On December 12, 2011, Duke Energy Progress and Duke Energy Florida sued the United States in the U.S. Court of Federal Claims. The lawsuit claims the Department of Energy breached a contract in failing to accept spent nuclear fuel under the Nuclear Waste Policy Act of 1982 and asserts damages for the cost of on-site storage. Duke Energy Progress and Duke Energy Florida assert damages for the period January 1, 2006 through December 31, 2010. Claims for all periods prior to 2006 have been resolved. On March 24, 2014, the U.S. Court of Federal Claims issued a judgment in favor of Duke Energy Progress and Duke Energy Florida on this matter, awarding amounts of $83 million and $21 million, respectively. The majority of the awards were recorded as a reduction to capital costs associated with construction of on-site storage facilities. Receipt of the award is expected in the third quarter of 2014. Duke Energy Progress and Duke Energy Florida may file subsequent damage claims as they incur additional costs.

Duke Energy Florida

Westinghouse Contract Litigation

On March 28, 2014 Duke Energy Florida filed a lawsuit against Westinghouse Electric Company (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 EPC agreement 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 agreement. Duke Energy Florida terminated the EPC agreement on January 28, 2014. 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 alleges damages under the EPC agreement 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. It is not possible to predict whether Duke Energy Florida will incur any further liability for terminating the EPC agreement 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.

Duke Energy Ohio

Antitrust Lawsuit

In January 2008, four plaintiffs, including individual, industrial and nonprofit customers, filed a lawsuit against Duke Energy Ohio in federal court in the Southern District of Ohio. Plaintiffs alleged Duke Energy Ohio conspired to provide inequitable and unfair price advantages for certain large business consumers by entering into non-public option agreements in exchange for their withdrawal of challenges to Duke Energy Ohio’s Rate Stabilization Plan (RSP) implemented in early 2005. In March 2014, a federal judge certified this matter as a class action. Trial has been set to begin on July 27, 2015. It is not possible to predict whether Duke Energy Ohio will incur any liability or to estimate the damages which may be incurred in connection with this lawsuit.

Duke Energy Indiana

Edwardsport IGCC

On December 11, 2012, Duke Energy Indiana filed an arbitration action against General Electric Company and Bechtel Corporation in connection with their work at the Edwardsport IGCC facility. Duke Energy Indiana is seeking damages of not less than $560 million. An arbitration hearing is scheduled for October 2014. Duke Energy Indiana cannot predict the outcome of this matter.

Other Litigation and Legal Proceedings

The Duke Energy Registrants are involved in other legal, tax and regulatory proceedings arising in the ordinary course of business, some of which involve significant amounts. The Duke Energy Registrants believe the final disposition of these proceedings will not have a material effect on their results of operations, cash flows or financial position. The table below presents recorded reserves based on management’s best estimate of probable loss for legal matters discussed above, excluding asbestos related reserves. Reserves are classified on the Condensed Consolidated Balance Sheets in Other within Deferred Credits and Other Liabilities and Other within Current Liabilities. The reasonably possible range of loss for all non-asbestos related matters in excess of recorded reserves is not material.

OTHER COMMITMENTS AND CONTINGENCIES

General

As part of their normal business, the Duke Energy Registrants are party to various financial guarantees, performance guarantees, and other contractual commitments to extend guarantees of credit and other assistance to various subsidiaries, investees, and other third parties. These guarantees involve elements of performance and credit risk, which are not fully recognized on the Condensed Consolidated Balance Sheets and have unlimited maximum potential payments. However, the Duke Energy Registrants do not believe these guarantees will have a material effect on their results of operations, cash flows or financial position.

In addition, the Duke Energy Registrants enter into various fixed-price, non-cancelable commitments to purchase or sell power, take-or-pay arrangements, transportation, or throughput agreements and other contracts that may or may not be recognized on their respective Condensed Consolidated Balance Sheets. Some of these arrangements may be recognized at fair value on their respective Condensed Consolidated Balance Sheets if such contracts meet the definition of a derivative and the normal purchase/normal sale (NPNS) exception does not apply. In most cases, the Duke Energy Registrants’ purchase obligation contracts contain provisions for price adjustments, minimum purchase levels, and other financial commitments.
