Upon closing, DPL will become a wholly-owned subsidiary of AES.   The transaction has been unanimously approved by each of DPLs and AES board of directors, but is subject to certain conditions, including receipt of the approval of DPL shareholders and, the expiration or termination of the applicable Hart-Scott-Rodino Act waiting period and the receipt of all required regulatory approvals from, among others, the FERC and the PUCO.  The parties anticipate receiving approvals and closing the transaction during the next six to nine months.   The Merger Agreement includes customary representations, warranties and restrictions, limitations and prohibitions as to actions we may or may not take in the period prior to consummation of the Merger or termination of the Merger Agreement.  Among other restrictions, without the consent of AES, the Merger Agreement limits our total capital spending, limits the extent to which we can obtain financing through long-term debt and equity, and we may not, without prior consent of AES, increase our quarterly common stock dividend of $0.3325 per share.   DPL expects to continue its policy of paying regular quarterly cash dividends until closing.  Dividends are expected to be paid on a prorated basis during the quarter in which the transaction closes.   The Merger Agreement also includes certain provisions whereby we have agreed to use our commercially reasonable efforts to replace DP&Ls existing $220.0 million revolving credit facility with a new facility that has a term of at least three years and in an amount equal to or greater than the current principal amount and generally on the same terms.  We have also agreed to use our commercially reasonable efforts, prior to the maturity date, to refinance the approximately $297.4 million principal amount of our 6.875% debt that is due in September 2011 and raise an additional principal amount of $125.0 million generally on the same terms and with a maturity of no less than five years.   The Merger Agreement restricts DPL from soliciting or initiating discussions with third parties regarding other proposals to acquire DPL, subject to certain exceptions for responding to unsolicited third party acquisition proposals and engaging in discussions and negotiations regarding unsolicited third party acquisition proposals.  The Merger Agreement also contains certain termination rights for both DPL and AES.  Upon termination under specified circumstances, DPL will be required to pay AES a termination fee of $106 million (or $53 million if the basis for termination of the Merger Agreement is DPLs election  to enter into an alternative transaction with a third party that has submitted an alternative acquisition proposal during the 30-day period after the date of the Merger Agreement).   The following lawsuits have been filed in connection with the proposed Merger of DPL and AES that was publicly announced on April 20, 2011 (See Item 1a, Risk Factors, for additional risks related to the Merger).  Each of these lawsuits seeks, among other things, one or more of the following:  to enjoin the defendants from consummating the proposed Merger until certain conditions are met, or to rescind the Merger, or to recover damages if the Merger is completed or to commence a sale process and/or obtain an alternative transaction or to promptly notice an annual shareholder meeting or to recover an unspecified amount of other damages and costs, including attorneys fees and expenses.   On April 21, 2011, a lawsuit was filed in the Court of Common Pleas of Montgomery County, Ohio, naming DPL and each member of DPLs board of directors, AES and Dolphin Sub, Inc. as defendants.  The lawsuit is a purported class action filed by Patricia A. Heinmuller on behalf of herself and an alleged class of DPL shareholders.  Plaintiff alleges, among other things, that DPLs directors breached their fiduciary duties in approving the proposed Merger of DPL and AES and that AES and Dolphin Sub, Inc. aided and abetted such breach.   On April 25, 2011, a lawsuit was filed in the Court of Common Pleas of Montgomery County, Ohio, naming DPL and each member of DPLs board of directors and AES as defendants.  The lawsuit is a purported class action and purported derivative action (on behalf of DPL) filed by The Austen Trust on behalf of itself and an alleged class of DPL shareholders and derivatively on behalf of DPL.  Plaintiff alleges, among other things, that DPLs directors breached their fiduciary duties in approving the proposed Merger of DPL and AES and that the defendants acted in concert in respect of the breach of their respective duties.   On April 26, 2011, a lawsuit was filed in the United States District Court, Southern District, Western Division, naming DPL and each member of DPLs board of directors, AES and Dolphin Sub, Inc. as defendants.  The lawsuit is a purported class action and purported derivative action (on behalf of DPL) filed by Stephen Kubiak on behalf of himself and an alleged class of DPL shareholders and derivatively on behalf of DPL.  Plaintiff alleges, among other things, that DPLs directors breached their fiduciary duties in approving the proposed Merger of DPL and that AES and Dolphin Sub, Inc. aided and abetted such breach.   A number of other similar putative class action lawsuits may be filed in federal or state court in Ohio by purported shareholders of DPL on behalf of themselves and other shareholders of DPL.  Such complaints may name as defendants DPL and its directors and, in certain cases, AES and Dolphin Sub, Inc.   The complaints may allege, among other things, that DPLs directors breached their fiduciary duties to shareholders of DPL in connection with DPLs entry into the proposed Merger with AES and that AES and Dolphin Sub, Inc. aided and abetted the directors purported breaches of fiduciary duties.  The complaints may seek, among other things, class action status, an order enjoining the proposed transaction, and attorneys fees and expenses.   DPL intends to vigorously defend against all of claims referred to above.   DPL expects to record transaction fees of approximately $20 million pre-tax during 2011.   Further information concerning the proposed merger, including a copy of the Merger Agreement, is included in DPLs Current Report on Form 8-K relating to the merger, filed with the SEC on April 20, 2011.  In addition, further information will be included in a proxy statement filed by us with the SEC in connection with the Merger.  </td></tr></table> 16.  Subsequent Events   On April 19, 2011, DPL and The AES Corporation, a Delaware corporation (AES), entered into an Agreement andfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescribes disclosed significant events or transactions that occurred after the balance sheet date, but before the issuance of the financial statements.
