The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. 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 accounting principles generally accepted in the U.S. for complete financial statements.

The financial statements and notes thereto should be read in conjunction with the financial statements and notes contained in each Registrant's 2010 Form 10-K (in the case of PPL and PPL Electric), in the Form 8-K dated June 24, 2011 (in the case of PPL Energy Supply), or the annual financial statements included in the 2011 Registration Statements (in the case of LKE, LG&E and KU). The results of operations for the three and six months ended June 30, 2011 are not necessarily indicative of the results to be expected for the full year ending December 31, 2011 or other future periods, because results for interim periods can be disproportionately influenced by various factors and developments and seasonal variations.

See Note 8 for additional information. Since PPL is consolidating WPD Midlands on a one-month lag, two months of WPD Midlands' operating results are included in PPL's results of operations for the three and six months ended June 30, 2011 with no comparable amounts for the same periods in 2010.

(LKE, LG&E and KU) LKE's, LG&E's and KU's financial statements and accompanying footnotes have been segregated to present pre-acquisition activity as the Predecessor and post-acquisition activity as the Successor. Predecessor activity covers the time period prior to November 1, 2010. Successor activity covers the time period after October 31, 2010. Certain accounting and presentation methods were changed to acceptable alternatives in the Successor financial statements to conform to PPL's accounting policies, which are discussed in the annual financial statements included in each 2011 Registration Statement for LKE, LG&E and KU.

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. 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 accounting principles generally accepted in the U.S. for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with accounting principles generally accepted in the U.S. 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, 2010 is derived from that Registrant's 2010 audited Balance Sheet.
