(a)	The Subsidiary Registrants are charged their proportionate share of corporate governance and other costs by unconsolidated affiliates that are consolidated affiliates of Duke Energy and Progress Energy. Corporate governance and other shared services costs are primarily related to human resources, employee benefits, legal and accounting fees, as well as other third party costs. These amounts are recorded in Operation, maintenance and other on the Condensed Consolidated Statements of Operations and Comprehensive Income.
(b)	The Subsidiary Registrants incur expenses related to certain indemnification coverages through Bison, Duke Energy’s wholly owned captive insurance subsidiary. These expenses are recorded in Operation, maintenance and other on the Condensed Consolidated Statements of Operations and Comprehensive Income.
(c)	Effective with the consummation of the merger between Duke Energy and Progress Energy, Duke Energy Carolinas and Duke Energy Progress began to participate in a JDA which allowed the collective dispatch of power plants between the service territories to reduce customer rates. Revenues from the sale of power under the JDA are recorded in Operating Revenues on the Condensed Consolidated Statements of Operations and Comprehensive Income. Expenses from the purchase of power under the JDA are recorded in Fuel used in electric generation and purchased power on the Condensed Consolidated Statements of Operations and Comprehensive Income.
(d)	Progress Energy charges a proportionate share of corporate governance and other costs to unconsolidated affiliates that are consolidated affiliates of Duke Energy. Corporate governance and other shared costs are primarily related to human resources, employee benefits, legal and accounting fees, as well as other third-party costs. These charges are recorded as an offset to Operation, maintenance and other in the Condensed Consolidated Statements of Operations and Comprehensive Income.

In addition to the amounts presented above, the Subsidiary Registrants record income associated with the rental of office space to consolidated affiliates of Duke Energy, as well as their proportionate share of certain charged expenses from affiliates of Duke Energy. The Duke Energy registrants participate in a money pool arrangement with Duke Energy and certain of its subsidiaries. See Note 6 for more information regarding money pool. As discussed in Note 11, certain trade receivables have been sold by Duke Energy Ohio and Duke Energy Indiana to CRC, an unconsolidated entity formed by a subsidiary of Duke Energy. The proceeds obtained from the sales of receivables are largely cash but do include a subordinated note from CRC for a portion of the purchase price. Rental income, interest income and interest expense on these transactions were not material for the three months ended March 31, 2013 and 2012.

In January 2012, Duke Energy Ohio recorded a non-cash after tax equity transfer of $28 million related to the sale of Vermilion to Duke Energy Indiana. Duke Energy Indiana recorded a non-cash after tax equity transfer of $26 million for the purchase of Vermillion from Duke Energy Ohio. See note 2 for further discussion.

Duke Energy Commercial Asset Management (DECAM) is a non-regulated, direct subsidiary of Duke Energy Ohio. DECAM conducts business activities, including the execution of commodity transactions, third party vendor and supply contracts and service contracts, for certain of Duke Energy's non-regulated entities. The commodity contracts that DECAM enters either do not qualify as hedges or are accounted for as undesignated contracts, thus the mark-to-market impacts of these contracts are reflected in Duke Energy Ohio's Condensed Consolidated Statements of Operations and Comprehensive Income. In addition, equal and offsetting mark-to-market impacts of intercompany contracts with non-regulated entities are reflected in Duke Energy Ohio's Condensed Consolidated Statements of Operations and Comprehensive Income representing the pass through of the economics of the original contracts to non-regulated entities in accordance with contractual arrangements between Duke Energy Ohio and non-regulated entities. Because it is not a rated entity, DECAM receives its credit support from Duke Energy or its non-regulated subsidiaries and not the regulated utility operations of Duke Energy Ohio. DECAM meets its funding needs through an intercompany loan agreement from a subsidiary of Duke Energy. DECAM also has the ability to loan money to the subsidiary of Duke Energy. DECAM had an outstanding intercompany loan payable with the subsidiary of Duke Energy of $99 million and $79 million as of March 31, 2013 and December 31, 2012, respectively. These amounts are recorded in Notes payable to affiliated companies on Duke Energy Ohio's Condensed Consolidated Balance Sheets. DECAM had no intercompany loan receivable with the subsidiary of Duke Energy as of March 31, 2013.
