The Duke Energy Registrants closely monitor the risks associated with commodity price changes and changes in interest rates on their operations and, where appropriate, use various commodity and interest rate instruments to manage these risks. Certain of these derivative instruments qualify for hedge accounting and are designated as hedging instruments, while others either do not qualify as hedges or have not been designated as hedges (hereinafter referred to as undesignated contracts). The Duke Energy Registrants' primary use of energy commodity derivatives is to hedge the generation portfolio against exposure to changes in the prices of power and fuel. Interest rate swaps are entered into to manage interest rate risk primarily associated with the Duke Energy Registrants' variable-rate and fixed-rate borrowings. Additionally, Duke Energy Carolinas', Duke Energy Progress' and Duke Energy Florida's nuclear decommissioning trust fund (NDTF) investment holdings may include certain derivative instruments, such as interest rate swaps and credit default swaps, as part of its overall investment strategy. As further discussed in Note 10 the NDTF's are managed by third party investment managers who have the discretion to make investment decisions within risk management guidelines determined by management of Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida. The fair value of these derivative instruments are included within Nuclear decommissioning trust funds on the Condensed Consolidated Balance Sheets and are not material to the investment balance at March 31, 2013 and December 31, 2012.

The accounting guidance for derivatives requires the recognition of all derivative instruments not identified as NPNS as either assets or liabilities at fair value in the Condensed Consolidated Balance Sheets. For derivative instruments that qualify for hedge accounting, the Duke Energy Registrants may elect to designate such derivatives as either cash flow hedges or fair value hedges. The Duke Energy Registrants offset fair value amounts recognized on the Condensed Consolidated Balance Sheets related to derivative instruments executed with the same counterparty under the same master netting agreement.

The operations of the USFE&G business segment meet the criteria for regulatory accounting treatment. Accordingly, for derivatives that would otherwise be designated as cash flow hedges within USFE&G, gains and losses are reflected as a regulatory liability or asset instead of as a component of accumulated other comprehensive income (AOCI). For derivatives that would otherwise be designated as fair value hedges or left undesignated within USFE&G, gains and losses associated with the change in fair value of these derivative contracts would be deferred as a regulatory liability or asset. As a result changes in fair value of these derivatives have no immediate earnings impact.

Within the Duke Energy Registrants' unregulated businesses, for derivative instruments that qualify for hedge accounting and are designated as cash flow hedges, the effective portion of the gain or loss is reported as a component of AOCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any gains or losses on the derivative that represent either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. For derivative instruments that qualify and are designated as a fair value hedge, the gain or loss on the derivative as well as the fully or partially offsetting loss or gain on the hedged item are recognized in earnings in the current period. The Duke Energy Registrants include the gain or loss on the derivative in the same line item as the offsetting loss or gain on the hedged item in the Condensed Consolidated Statements of Operations. Additionally, the Duke Energy Registrants enter into derivative agreements that are economic hedges that either do not qualify for hedge accounting or have not been designated as a hedge. The changes in fair value of these undesignated derivative instruments are reflected in current earnings.

The Duke Energy Registrants are exposed to the impact of market changes in the future prices of electricity (energy, capacity and financial transmission rights), coal, natural gas and emission allowances (SO2, seasonal NOX and annual NOX) as a result of their energy operations such as electricity generation and the transportation and sale of natural gas. With respect to commodity price risks associated with electricity generation, the Duke Energy Registrants are exposed to changes including, but not limited to, the cost of the coal and natural gas used to generate electricity, the prices of electricity sold in wholesale markets, the cost of capacity and electricity purchased for resale in wholesale markets and the cost of emission allowances primarily at the Duke Energy Registrants' coal fired power plants. Risks associated with commodity price changes on future operations are closely monitored and, where appropriate, various commodity contracts are used to mitigate the effect of such fluctuations on operations. Exposure to commodity price risk is influenced by a number of factors, including, but not limited to, the term of the contract, the liquidity of the market and delivery location.

At March 31, 2013, there were no open commodity derivative instruments that were designated as fair value hedges.

At March 31, 2013, open commodity derivative instruments that were designated as cash flow hedges were not material.

The Duke Energy Registrants use derivative contracts as economic hedges to manage the market risk exposures that arise from providing electricity generation and capacity to large energy customers, energy aggregators, retail customers and other wholesale companies. Undesignated contracts may include contracts not designated as a hedge, 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. These contracts expire as late as 2017.

Undesignated contracts also include contracts associated with operations that Duke Energy continues to wind down or has included as discontinued operations. As these undesignated contracts expire as late as 2021, Duke Energy has entered into economic hedges that leave it minimally exposed to changes in prices over the duration of these contracts.

Duke Energy Carolinas and Duke Energy Progress use derivative contracts primarily as economic hedges to manage the market risk exposures that arise from electricity generation. Duke Energy Carolinas and Duke Energy Progress have also entered into firm power sale agreements, which are accounted for as derivative instruments, as part of the Interim FERC Mitigation in connection with Duke Energy's merger with Progress Energy. Duke Energy Carolinas' undesignated contracts as of March 31, 2013, are primarily associated with forward sales and purchases of power. Duke Energy Progress' undesignated contracts as of March 31, 2013, are primarily associated with forward purchases of fuel used in electricity generation.

Duke Energy Florida uses derivative contracts primarily as economic hedges to manage the market risk exposures that arise from electricity generation. Undesignated contracts at March 31, 2013, are primarily associated with forward purchases of fuel used in electricity generation.

Duke Energy Ohio uses derivative contracts as economic hedges to manage the market risk exposures that arise from providing electricity generation and capacity to large energy customers, energy aggregators, retail customers and other wholesale companies. Undesignated contracts at March 31, 2013, are primarily associated with forward sales and purchases of power, coal and gas for the Commercial Power segment.

Duke Energy Indiana uses derivative contracts as economic hedges to manage the market risk exposures that arise from electricity generation. Undesignated contracts at March 31, 2013, are primarily associated with forward purchases and sales of power, and financial transmission rights.

The table below shows information relating to the volume of the Duke Energy registrants outstanding commodity derivative activity. Amounts disclosed represent the notional volumes of commodities contracts accounted for at fair value. For option contracts, notional amounts include only the delta-equivalent volumes which represent the notional volumes times the probability of exercising the option based on current price volatility. Volumes associated with contracts qualifying for the NPNS exception have been excluded from the table below. Amounts disclosed represent the absolute value of notional amounts. The Duke Energy Registrants have netted contractual amounts where offsetting purchase and sale contracts exist with identical delivery locations and times of delivery. Where all commodity positions are perfectly offset, no quantities are shown below. For additional information on notional dollar amounts of debt subject to derivative contracts accounted for at fair value, see “Interest Rate Risk” section below.

The Duke Energy Registrants are exposed to risk resulting from changes in interest rates as a result of their issuance or anticipated issuance of variable and fixed-rate debt and commercial paper. Interest rate exposure is managed by limiting variable-rate exposures to a percentage of total debt and by monitoring the effects of market changes in interest rates. To manage risk associated with changes in interest rates, the Duke Energy Registrants may enter into financial contracts; primarily interest rate swaps and U.S. Treasury lock agreements. Additionally, in anticipation of certain fixed-rate debt issuances, a series of forward starting interest rate swaps may be executed to lock in components of the market interest rates at the time and terminated prior to or upon the issuance of the corresponding debt. When these transactions occur within a business that meets the criteria for regulatory accounting treatment, these contracts may be treated as undesignated and any pre-tax gain or loss recognized from inception to termination of the hedges would be recorded as a regulatory liability or asset and amortized as a component of interest expense over the life of the debt. In businesses that don't meet the criteria for regulatory accounting treatment, these derivatives may be designated as hedges whereby any pre-tax gain or loss recognized from inception to termination of the hedges would be recorded in AOCI and amortized as a component of interest expense over the life of the debt.

Duke Energy has a combination foreign exchange, pay fixed-receive floating interest rate swap to fix the US Dollar equivalent payments on a floating rate Chilean debt issue.

As discussed above, within the Duke Energy Carolinas, Duke Energy Progress, and Duke Energy Florida NDTFs, certain of the fixed income investment managers have authorization to use interest rate swaps and credit default swaps in their investment strategies to either manage risk or enhance returns. Notional amounts for these contracts are not included in the table below as they are not material to the investment balance at March 31, 2013 and December 31, 2012.

The following table shows the notional amounts for derivatives related to interest rate risk.

The tables below show the balance sheet location of the derivative contracts subject to enforceable master netting agreements and include collateral posted to offset the net position. This disclosure is intended to enable users to evaluate the effect of netting arrangements on Duke Energy's financial position. The amount shown in the net position column is calculated by counterparty.

Most derivatives are entered into with counterparties under enforceable master netting agreements, or with an Independent System Operator (ISO) such as MISO or PJM. Derivatives entered into with a clearinghouse are usually over-collateralized due to the requirement to post initial margin upon entering into contracts. The amounts shown as offset are limited by the amount of exposure to a counterparty such that an over collateralized position at one counterparty is not allowed to reduce an under collateralized position at another counterparty. In addition to the amounts shown as offset, in the table, Duke Energy may also have available accounts receivable or accounts payable, that are subject to master netting agreements that would offset exposures in the event of bankruptcy.

The amounts shown as offset are limited by the amount of exposure to a counterparty such that an over collateralized position at one counterparty is not allowed to reduce an under collateralized position at another counterparty. In addition to the amounts shown as offset, in the table, Duke Energy Progress may also have available accounts receivable or accounts payable to offset exposures in the events of bankruptcy.
