Item 4.01     Changes in Registrant’s Certifying Accountant (Dismissal and Appointment)

On November 28, 2011, in connection with the consummation of the Merger, (i) the Board of Directors of DPL approved the dismissal of KPMG, LLP (“KPMG”) as DPL’s independent registered public accounting firm effective upon completion of KPMG’s audit procedures as of and with respect to the period ended November 27, 2011, and (ii) the Board of Directors of The Dayton Power and Light Company (“DP&L”) approved the dismissal of KPMG as its independent registered public accounting firm effective at the completion of KPMG’s audit of DP&L’s December 31, 2011 financial statements.  Also in connection with the consummation of the Merger, (a) DPL’s Board of Directors appointed Ernst & Young LLP (“Ernst & Young”), AES’s independent registered public accounting firm, as its independent registered public accounting firm for the period November 28, 2011 through December 31, 2011 and for the fiscal year ending December 31, 2012, and (b) DP&L’s Board of Directors appointed Ernst & Young as its independent registered public accounting firm for the fiscal year ending December 31, 2012.

KPMG’s audit report dated February 17, 2011 on DPL’s consolidated financial statements as of and for the years ended December 31, 2010 and December 31, 2009 included in its Form 10-K filed February 17, 2011 did not contain an adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope, or accounting principles.  KPMG’s audit report dated February 17, 2011 on DP&L’s financial statements as of and for the years ended December 31, 2010 and December 31, 2009 included in its Form 10-K filed February 17, 2011 did not contain an adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the years ended December 31, 2010 and December 31, 2009, and the subsequent interim period through the date of this filing, there were no disagreements between either DPL and KPMG or DP&L and KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to their satisfaction, would have caused KPMG to make reference to the subject matter of the disagreement in connection with its audit report.

During the years ended December 31, 2010 and December 31, 2009, and the subsequent interim period through the date of this filing, there were no reportable events (as defined in Regulation S-K Item 304 (a)(1)(v)).

Each of DPL and DP&L have requested that KPMG furnish it with a letter addressed to the SEC stating whether or not it agrees with the disclosures set forth above. A copy of such letters will

be filed as an amendment to this Form 8-K within ten (10) business days of the filing of this Form 8-K.

Neither DPL or DP&L has consulted with Ernst & Young during its two most recent fiscal years or during any subsequent interim period prior to its appointment as auditor regarding any matters described in Item 304(a)(2)(i) or Item 304(a)(2)(ii) of Regulation S-K.
