NEW ACCOUNTING STANDARDSThe following new accounting standards were adopted by the Duke Energy Registrants subsequent to June 30, 2012, and the impact of such adoption, if applicable, has been presented in the accompanying Condensed Consolidated Financial Statements: Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 210 — Balance SheetIn January 2013, the FASB issued revised accounting guidance to amend the existing disclosure requirements for offsetting financial assets and liabilities to enhance current disclosures, as well as to improve comparability of balance sheets prepared under U.S. GAAP and International Financial Reporting Standards (IFRS). The revised disclosure guidance affects all companies that have financial instruments and derivative instruments that are either offset in the balance sheet (i.e., presented on a net basis) or subject to an enforceable master netting arrangement and/or similar agreement. The revised guidance requires that certain enhanced quantitative and qualitative disclosures be made with respect to a company's netting arrangements and/or rights of setoff associated with its financial instruments and/or derivative instruments including associated collateral. For the Duke Energy Registrants, the revised disclosure guidance was effective on a retrospective basis for interim and annual periods beginning January 1, 2013. Other than additional disclosures, this revised guidance does not impact the Duke Energy Registrants' results of operations, cash flows or financial position.ASC 220 — Comprehensive IncomeIn February 2013, the FASB amended the existing requirements for presenting comprehensive income in financial statements to improve the reporting of reclassifications out of AOCI. The amendments in the guidance seek to attain that objective by requiring an entity to report the effect of significant reclassifications out of AOCI on the respective line items in net income if the amount being reclassified is required under U.S. GAAP to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of AOCI is reclassified to a balance sheet account (for example, property, plant and equipment) instead of directly to income or expense in the same reporting period. For the Duke Energy Registrants, this revised guidance was effective on a prospective basis for interim and annual periods beginning January 1, 2013. Other than additional disclosures and a change in the presentation of the consolidated statement of equity, this revised guidance does not impact the Duke Energy Registrants' results of operations, cash flows or financial position. The following new Accounting Standards Update (ASU) has been issued, but has not yet been adopted by Duke Energy, as of June 30, 2013.ASC 830—Foreign Currency Matters. In March 2013, the FASB issued revised accounting guidance to resolve the diversity in practice about the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business (other than a sale of in substance real estate) within a foreign entity. In addition, the amendments resolve the diversity in practice for the release of the cumulative translation adjustment involving business combinations achieved in stages by either a Duke investor or a third party acquirer. For the Duke Energy Registrants, the revised accounting guidance is effective on a prospective basis for interim and annual periods beginning January 1, 2014. The revised guidance will impact the timing of the recognition of the cumulative translation adjustment for certain future transactions and therefore, could impact the Duke Energy Registrants' results of operations, cash flows and financial position.falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for reporting accounting changes and error corrections.
