Interim Financial Statements (PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU) Capitalized terms and abbreviations appearing in the unaudited combined notes to condensed financial statements are defined in the glossary. Dollars are in millions, except per share data, unless otherwise noted. When appropriate, PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU are named specifically at each discussion heading or therein for their related activities and disclosures.  The accompanying unaudited condensed financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with GAAP are reflected in the condensed financial statements. All adjustments are of a normal recurring nature, except as otherwise disclosed. Each Registrant's Balance Sheet at December 31, 2012 is derived from that Registrant's 2012 audited Balance Sheet. The financial statements and notes thereto should be read in conjunction with the financial statements and notes contained in each Registrant's 2012 Form 10-K. The results of operations for the three and six months ended June 30, 2013, are not necessarily indicative of the results to be expected for the full year ending December 31, 2013, or other future periods, because results for interim periods can be disproportionately influenced by various factors, developments and seasonal variations. The classification of certain prior period amounts has been changed to conform to the presentation in the June 30, 2013 financial statements. falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name FASB Interpretation (FIN) -Number 46R -Paragraph 4, 14, 15 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
