The Duke Energy Registrants consolidate assets and liabilities from acquisitions as of the purchase date, and include earnings from acquisitions in consolidated earnings after the purchase date.

On July 2, 2012, Duke Energy completed the merger contemplated by the Agreement and Plan of Merger (Merger Agreement), among Diamond Acquisition Corporation, a North Carolina corporation and Duke Energy's wholly owned subsidiary (Merger Sub) and Progress Energy, a North Carolina corporation engaged in the regulated utility business of generation, transmission and distribution and sale of electricity in portions of North Carolina, South Carolina and Florida. As a result of the merger, Merger Sub was merged into Progress Energy and Progress Energy became a wholly owned subsidiary of Duke Energy.

The merger between Duke Energy and Progress Energy provides increased scale and diversity with potentially enhanced access to capital over the long term and a greater ability to undertake the significant construction programs necessary to respond to increasing environmental regulation, plant retirements and customer demand growth. Duke Energy's business risk profile is expected to improve over time due to the increased proportion of the business that is regulated. Additionally, cost savings, efficiencies and other benefits are expected from the combined operations.

Progress Energy's shareholders received 0.87083 shares of Duke Energy common stock in exchange for each share of Progress Energy common stock outstanding as of July 2, 2012. Generally, all outstanding Progress Energy equity-based compensation awards were converted into Duke Energy equity-based compensation awards using the same ratio. The merger was structured as a tax-free exchange of shares.

Refer to Note 5 for information regarding Progress Energy merger shareholder litigation.

Federal Energy Regulatory Commission. On June 8, 2012, the FERC conditionally approved the merger including Duke Energy and Progress Energy's revised market power mitigation plan, the Joint Dispatch Agreement (JDA) and the joint Open Access Transmission Tariff (OATT). The revised market power mitigation plan provides for the acceleration of one transmission project and the construction of seven other transmission projects (Long-term FERC Mitigation) and interim firm power sale agreements during the construction of the transmission projects (Interim FERC Mitigation). The Long-term FERC Mitigation will increase power imported into the Duke Energy Carolinas and Progress Energy Carolinas service areas and enhance competitive power supply options in the service areas. The construction of these projects will occur over the next two to three years. In conjunction with the Interim FERC Mitigation, Duke Energy Carolinas and Progress Energy Carolinas entered into power sale agreements with various counterparties that were effective with the consummation of the merger. These agreements, or similar power sale agreements, will be in place until the Long-term FERC Mitigation is operational. Under the agreements Duke Energy will deliver around-the-clock power during the winter and summer in quantities that vary by season and by peak period.

The FERC order requires an independent party to monitor whether the power sale agreements remain in effect during construction of the transmission projects and provide quarterly reports to the FERC regarding the status of construction of the transmission projects.

On June 25, 2012, Duke Energy and Progress Energy accepted the conditions imposed by the FERC.

On July 10, 2012, certain intervenors requested a rehearing seeking to overturn the June 8, 2012 order by the FERC. On August 8, 2012, FERC granted rehearing for further consideration.

North Carolina Utilities Commission and Public Service Commission of South Carolina. In September 2011, Duke Energy and Progress Energy reached settlements with the Public Staff of the North Carolina Utilities Commission (NC Public Staff) and the South Carolina Office of Regulatory Staff (ORS) and certain other interested parties in connection with the regulatory proceedings related to the merger, the JDA and the OATT that were pending before the NCUC and PSCSC. These settlements were updated in May 2012 to reflect the results of ongoing merger related applications pending before the FERC.

On June 29, 2012, the NCUC approved the merger application and the JDA application. On July 2, 2012, the PSCSC approved the JDA application subject to Duke Energy Carolinas and Progress Energy Carolinas providing their South Carolina retail customers pro rata benefits equivalent to those approved by the NCUC in its merger approval order.

On July 6, 2012, the NCUC issued an order initiating investigation and scheduling hearings on the Duke Energy board of directors' decision on July 2, 2012, to replace William D. Johnson with James E. Rogers as President and CEO of Duke Energy subsequent to the merger close, as well as other related matters. On November 29, 2012, a settlement agreement was reached and was subsequently approved by the NCUC on December 3, 2012. See Note 4 for further information.

As part of these settlements, approval of the merger by the NCUC and PSCSC, and resolution of the subsequent investigation by the NCUC, Duke Energy Carolinas and Progress Energy Carolinas agreed to the conditions and obligations listed below.

Kentucky Public Service Commission. On June 24, 2011, Duke Energy and Progress Energy filed a settlement agreement with the Kentucky Attorney General. On August 2, 2011, the KPSC issued an order conditionally approving the merger and required Duke Energy and Progress Energy to accept all conditions contained in the order. Duke Energy and Progress Energy requested and were granted rehearing on the limited issue of the wording of one condition relating to the composition of Duke Energy's post-merger board of directors. On October 28, 2011, the KPSC issued its order approving a settlement with the Kentucky Attorney General on the revised condition relating to the composition of the post-merger Duke Energy board. Duke Energy and Progress Energy filed their acceptance of the condition on November 2, 2011. Duke Energy Kentucky agreed to (i) not file new gas or electric base rate applications for two years from the date of the KPSC's final order in the merger proceedings, (ii) make five annual shareholder contributions of $165,000 to support low-income weatherization efforts and economic development within Duke Energy Kentucky's service territory and (iii) not seek recovery from retail customers for any of their allocable share of merger related costs.

The following pre-tax consummation charges were recognized upon closing of the merger and are included in the Duke Energy Registrant's Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2012.

(in millions)	Duke Energy		Duke Energy Carolinas		Progress Energy		Progress Energy Carolinas		Progress Energy Florida		Duke Energy Ohio		Duke Energy Indiana
FERC Mitigation	$	117	$	46	$	71	$	71	$	―	$	―	$	―
Severance costs		196		63		82		55		27		21		18
Community support, charitable contributions and other		169		79		74		63		11		7		6
Total	$	482	$	188	$	227	$	189	$	38	$	28	$	24

The FERC Mitigation charges reflect the portion of transmission project costs that were probable of disallowance, the impairment of the carrying value of the generation assets serving the Interim FERC Mitigation, and the mark-to-market loss recognized on the power sale agreements upon closing of the merger. The charges related to the transmission projects and the impairment of the carrying value of generation assets were recorded within Impairment charges in the Consolidated Statements of Operations for the year ended December 31, 2012. The mark-to-market loss on the interim power sale agreements was recorded in Regulated electric operating revenues in the Consolidated Statements of Operations for the year ended December 31, 2012. Subsequent changes in the fair value of the interim power sale agreements over the life of the contracts and realized gains or losses on the interim contract sales are also recorded within Regulated electric operating revenues. The ability to successfully defend future recovery of a portion of the transmission projects in rates and any future changes to estimated transmission project costs could impact the amount that is not expected to be recovered.

In conjunction with the merger, in November 2011, Duke Energy and Progress Energy each offered a voluntary severance plan (VSP) to certain eligible employees. VSP and other severance costs incurred during the year ended December 31, 2012, were recorded primarily within Operation, maintenance and other in the Consolidated Statements of Operations for the year ended December 31, 2012. See Note 21 for further information related to employee severance expenses.

Community support, charitable contributions and other reflect (i) the unconditional obligation to provide funding at a level comparable to historic practices over the next four years, and (ii) financial and legal advisory costs that were incurred upon the closing of the merger, retention and relocation costs paid to certain employees. These charges were recorded within Operation, maintenance and other in the Consolidated Statements of Operations for the year ended December 31, 2012.

Pursuant to the merger, all Progress Energy common shares were exchanged at the fixed exchange ratio of 0.87083 common shares of Duke Energy for each Progress Energy common share. The total consideration transferred in the merger was based on the closing price of Duke Energy common shares on July 2, 2012, and was calculated as follows:

(dollars in millions, except per share amounts; shares in thousands)
Progress Energy common shares outstanding at July 2, 2012		296,116
Exchange ratio		0.87083
Duke Energy common shares issued for Progress Energy common shares outstanding		257,867
Closing price of Duke Energy common shares on July 2, 2012	$	69.84
Purchase price for common stock	$	18,009
Fair value of outstanding earned stock compensation awards		62
Total purchase price	$	18,071

Progress Energy's stock-based compensation awards, including performance shares and restricted stock, were replaced with Duke Energy awards upon consummation of the merger. In accordance with accounting guidance for business combinations, a portion of the fair value of these awards is included in the purchase price as it represents consideration transferred in the merger.

The fair value of Progress Energy's assets acquired and liabilities assumed was determined based on significant estimates and assumptions, including level 3 inputs, which are judgmental in nature. The estimates and assumptions include the projected timing and amount of future cash flows; discount rates reflecting risk inherent in the future cash flows and future market prices. The fair value of Progress Energy's assets acquired and liabilities assumed utilized for the purchase price allocation are preliminary. These amounts are subject to revision until the valuations are completed, and to the extent that additional information is obtained about the facts and circumstances that existed as of the acquisition date, including but not limited to the resolution of matters pertaining to the retirement of CR3 as well as certain other tax and contingency related items.

The significant assets and liabilities for which preliminary valuation amounts are reflected as of the filing of this Form 10-K include the fair value of the acquired long-term debt, asset retirement obligations, capital leases and pension and other post-retirement benefit (OPEB) plans. Additionally the February 5, 2013 announcement of the decision to retire Progress Energy Florida's Crystal River Unit 3, reflects additional information related to the facts and circumstances that existed as of the acquisition date. See Note 4 for additional information related to Crystal River Unit 3. As such, the Progress Energy assets acquired and liabilities assumed are presented as if the retirement of Crystal River Unit 3 occurred on the acquisition date. The fair value of the outstanding stock compensation awards is included in the purchase price as consideration transferred.

The majority of Progress Energy's operations are subject to the rate-setting authority of the FERC, the NCUC, the PSCSC, and the FPSC and are accounted for pursuant to U.S. GAAP, including the accounting guidance for regulated operations. The rate-setting and cost recovery provisions currently in place for Progress Energy's regulated operations provide revenues derived from costs, including a return on investment of assets and liabilities included in rate base. Except for long-term debt, asset retirement obligations, capital leases, pension and OPEB plans and the wholesale portion of Progress Energy Florida's Crystal River Unit 3, the fair values of Progress Energy's tangible and intangible assets and liabilities subject to these rate-setting provisions approximate their carrying values, and the assets and liabilities acquired and pro forma financial information do not reflect any net adjustments related to these amounts. The difference between fair value and the pre-merger carrying amounts for Progress Energy's long-term debt, asset retirement obligations, capital leases and pension and OPEB plans for the regulated operations were recorded as Regulatory assets.

The excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed was recognized as goodwill at the acquisition date. The goodwill reflects the value paid primarily for the long-term potential for enhanced access to capital as a result of the company's increased scale and diversity, opportunities for synergies, and an improved risk profile. The goodwill resulting from Duke Energy's merger with Progress Energy was preliminarily allocated entirely to the USFE&G segment, but is subject to change as additional information is obtained. None of the goodwill recognized is deductible for income tax purposes, and as such, no deferred taxes have been recorded related to goodwill.

The preliminary purchase price allocation of the merger is presented in the following table.

(in millions)
Current assets	$	3,204
Property, plant and equipment		23,279
Goodwill		12,467
Other long-term assets, excluding goodwill		9,994
Total assets		48,944
Current liabilities, including current maturities of long-term debt		3,581
Long-term liabilities, preferred stock and noncontrolling interests		10,546
Long-term debt		16,746
Total liabilities and preferred stock		30,873
Total purchase price	$	18,071

The preliminary purchase price allocation in the table above reflects refinements made to the fair values of the assets acquired and liabilities assumed since the acquisition date and also reflects the retirement of Progress Energy Florida's Crystal River Unit 3 as if it occurred on the acquisition date. These resulted in an increase to the fair value of Other long-term assets, excluding goodwill of $1,845 million, an increase in Current liabilities of $14 million and an increase in Long-term liabilities, preferred stock and noncontrolling interests of $232 million. The fair value of Current assets decreased by $54 million and Property, plant and equipment decreased by $1,670 million. These changes to the assets acquired and liabilities assumed resulted in an increase to goodwill of $125 million and had an immaterial impact on the amortization of the purchase accounting adjustments recorded during 2012.

The following unaudited pro forma financial information reflects the consolidated results of operations of Duke Energy and reflects the amortization of purchase price adjustments assuming the merger had taken place on January 1, 2011. The unaudited pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the consolidated results of operations that would have been achieved or the future consolidated results of operations of Duke Energy. This information is preliminary in nature and subject to change based on final purchase price adjustments.

Non-recurring merger consummation, integration and other costs incurred by Duke Energy and Progress Energy during the period have been excluded from the pro forma earnings presented below. After-tax non-recurring merger consummation, integration and other costs incurred by both Duke Energy and Progress Energy were $413 million and $85 million for the years ended December 31, 2012 and 2011, respectively. The pro forma financial information also excludes potential future cost savings or non-recurring charges related to the merger.

	Year Ended December 31,
(in millions, except per share amounts)	2012		2011
Revenues	$	23,976	$	23,445
Net Income Attributable to Duke Energy Corporation		2,417		2,397
Basic and Diluted Earnings Per Share		3.43		3.41

In December 2012, International Energy acquired Iberoamericana de Energía Ibener, S.A. (Ibener) of Santiago, Chile for cash consideration of $415 million. This acquisition included the 140 MW Duqueco hydroelectric generation complex consisting of two run-of-the-river plants located in southern Chile vicinity. The preliminary purchase accounting entries consisted primarily of $383 million of property, plant and equipment, $30 million of intangible assets, $57 million of deferred income tax liabilities, and $59 million of goodwill. The fair value of the assets acquired and liabilities assumed utilized for the purchase price allocation are preliminary and subject to revision until the valuations are completed and to the extent that additional information is obtained about the facts and circumstances that existed as of the acquisition date. In connection with the acquisition, a $190 million six-month bridge loan and a $200 million revolving loan under a credit agreement were executed with a commercial bank. Both loans are collateralized with cash deposits equal to 101% of the loan amounts, and therefore no net proceeds from the financings exist as of December 31, 2012. The $190 million bridge loan is classified in Current maturities of long-term debt and the related cash collateral deposit is classified as Current Assets on the Consolidated Balance Sheets as of December 31, 2012. The $200 million, fully cash-collateralized revolving loan is due on December 20, 2013 and International Energy has the right to extend the term for additional 1 year terms, not to exceed a final maturity of 13 years from the date of the initial funding. The revolving loan is classified as Long-term Debt and the related cash collateral deposits are classified as restricted cash within Investments and Other Assets on the Consolidated Balance Sheets as of December 31, 2012.

In December 2010, Duke Energy completed the previously announced agreement with investment funds managed by Alinda to sell a 50% ownership interest in DukeNet Communications, LLC (DukeNet). As a result of the disposition transaction, DukeNet and Alinda became equal 50% owners in the new joint venture. Duke Energy received $137 million in cash. The DukeNet disposition transaction resulted in a pre-tax gain of $139 million, which was recorded in Gains on Sales of Other Assets and Other, net in the Consolidated Statements of Operations. The pre-tax gain reflects the gain on the disposition of Duke Energy's 50% interest in DukeNet, as well as the gain resulting from the re-measurement to fair value of Duke Energy's retained noncontrolling interest. Effective with the closing of the DukeNet disposition transaction, on December 20, 2010, DukeNet is no longer consolidated into Duke Energy's consolidated financial statements and is now accounted for by Duke Energy as an equity method investment.

On January 12, 2012, after receiving approvals from the FERC and the IURC on August 12, 2011 and December 28, 2011, respectively, Duke Energy Vermillion II, LLC (Duke Energy Vermillion), an indirect wholly owned subsidiary of Duke Energy Ohio, completed the sale of its 75% undivided ownership interest in the Vermillion Generating Station (Vermillion) to Duke Energy Indiana and Wabash Valley Power Association (WVPA). Upon the closing of the sale, Duke Energy Indiana and WVPA held 62.5% and 37.5% interests in Vermillion, respectively. Duke Energy Ohio received net proceeds of $82 million, consisting of $68 million and $14 million from Duke Energy Indiana and WVPA, respectively. Following the transaction, Duke Energy Indiana retired Gallagher Units 1 and 3 effective February 1, 2012.

As Duke Energy Indiana is an affiliate of Duke Energy Vermillion the transaction has been accounted for as a transfer between entities under common control with no gain or loss recorded and did not have a significant impact to Duke Energy Ohio or Duke Energy Indiana's results of operations. The proceeds received from Duke Energy Indiana are included in Net proceeds from the sales of other assets on Duke Energy Ohio's Consolidated Statements of Cash Flows. The cash paid to Duke Energy Ohio is included in Capital expenditures on Duke Energy Indiana's Consolidated Statements of Cash Flows. Duke Energy Ohio and Duke Energy Indiana recognized non-cash equity transfers of $28 million and $26 million, respectively, in their Consolidated Statements of Common Stockholder's Equity on the transaction representing the difference between cash exchanged and the net book value of Vermillion. These amounts are not reflected in Duke Energy's Consolidated Statements of Cash Flows or Consolidated Statements of Equity as the transaction is eliminated in consolidation.

The proceeds from WVPA are included in Net proceeds from the sales of other assets, and sale of and collections on notes receivable on Duke Energy and Duke Energy Ohio's Consolidated Statements of Cash Flows. In the second quarter of 2011, Duke Energy Ohio recorded a pre-tax impairment charge of $9 million to adjust the carrying value of the proportionate share of Vermillion to be sold to WVPA to the proceeds to be received from WVPA less costs to sell. The sale of the proportionate share of Vermillion to WVPA did not result in a significant additional gain or loss upon close of the transaction.

In April 2012, Duke Energy executed a joint venture agreement with Sumitomo Corporation of America (SCOA). Under the terms of the agreement, Duke Energy and SCOA each own a 50% interest in the joint venture (DS Cornerstone, LLC), which owns two wind generation projects. The facilities began commercial operations in June 2012 and August 2012. Duke Energy and SCOA also negotiated a $330 million, Construction and 12-year amortizing Term Loan Facility, on behalf of the borrower, a wholly owned subsidiary of the joint venture. The loan agreement is non-recourse to Duke Energy. Duke Energy received proceeds of $319 million upon execution of the loan agreement. This amount represents reimbursement of a significant portion of Duke Energy's construction costs incurred as of the date of the agreement. See Note 18 for further information.

The following table summarizes net cash proceeds related to the sales of Other assets not discussed above.

(in millions)		Duke Energy		Duke Energy Carolinas		Duke Energy Ohio		Duke Energy Indiana
Year Ended December 31,
2012^(a)		$	187	$	1	$	6	$	—
2011			12		2		7		1
2010			160		8		13		—

(a)	Duke Energy amount relates to proceeds from the disposition of non-core business assets within the Commercial Power segment for which no material gain or loss was recognized.

Included in Income From Discontinued Operations, net of tax on the Consolidated Statements of Operations are amounts related to adjustments for prior sales of diversified businesses. These adjustments are generally due to indemnifications provided for certain legal, tax and environmental matters. See Note 7 for further discussion of indemnifications. The ultimate resolution of these matters could result in additional adjustments in future periods.

For the year ended December 31, 2012, Duke Energy's and Progress Energy's Income From Discontinued Operations, net of tax was primarily related to resolution of litigation associated with Progress Energy's former synthetic fuel operations and reversal of certain environmental indemnification liabilities for which the indemnification period expired during 2012. See Note 5 for more information regarding these operations.
