Actual results could differ from those estimates. Items subject to such estimates and assumptions include: the carrying amount and estimated useful lives of long-lived assets; impairment of goodwill, long-lived assets and equity method investments; valuation allowances for receivables and deferred tax assets; the recoverability of deferred regulatory assets; the estimation of deferred regulatory liabilities; the fair value of financial instruments; the fair value of assets and liabilities acquired in a business combination accounted for under the purchase method; the determination of noncontrolling interest using the hypothetical liquidation at book value (“HLBV”) method for certain wind generation partnerships; pension liabilities; environmental liabilities; and potential litigation claims and settlements. </font></p><p style='margin-top:6pt; margin-bottom:6pt'><font style="font-family:Times New Roman;font-size:10pt;margin-left:27.35px;">On January 1, 2011, the Company changed its estimates related to depreciation on property, plant and equipment at its Brazilian concessionary utility and generation businesses. Based on information received from regulators, the depreciation rates and salvage values for its concession assets were adjusted on a prospective basis to reflect a remuneration basis, which represents the reimbursement expected by the Company at the end of the respective concession periods. For the year ended December 31, 2011, the impact to the consolidated statement of operations was an increase in depreciation expense of $68 million and a decrease in net income attributable to The AES Corporation of $18 million, or $0.02 per share.</font></p><p style='margin-top:0pt; margin-bottom:0pt'> </p>

CY2010	us-gaap	Debt Instrument Restrictive Covenants DebtInstrumentRestrictiveCovenants	Recourse Debt Covenants and Guarantees Certain of the Company’s obligations under the senior secured credit facility are guaranteed by its direct subsidiaries through which the Company owns its interests in the AES Shady Point, AES Hawaii, AES Warrior Run and AES Eastern Energy businesses. On December 30, 2011, AES Eastern Energy filed for bankruptcy and was deconsolidated. See Note 1—General and Summary of Significant Accounting Policies for additional information. The Company’s obligations under the senior secured credit facility are, subject to certain exceptions, secured by: (i)         all of the capital stock of domestic subsidiaries owned directly by the Company and 65% of the capital stock of certain foreign subsidiaries owned directly or indirectly by the Company; and (ii)         certain intercompany receivables, certain intercompany notes and certain intercompany tax sharing agreements. The senior secured credit facility is subject to mandatory prepayment under certain circumstances, including the sale of a guarantor subsidiary. In such a situation, the net cash proceeds from the sale of a Guarantor or any of its subsidiaries must be applied pro rata to repay the term loan using 60% of net cash proceeds, reduced to 50% when and if the parent’s recourse debt to cash flow ratio is less than 5:1. The lenders have the option to waive their pro rata redemption.

CY2011	us-gaap	Segment Reporting General Information SegmentReportingGeneralInformation	During the first quarter of 2012, the Company completed the restructuring of its operational management and reporting process. The management reporting structure is organized along two lines of business – Generation and Utilities, each led by a Chief Operating Officer. The segment reporting structure primarily uses the Company’s management reporting structure as its foundation to reflect how the Company manages the business internally with further aggregation by geographic regions to provide better socio-political-economic understanding of our business. Upon the application of the accounting guidance for segment reporting, the Company concluded that Tietê, our 2,663 MW hydro generation business in Brazil, met the quantitative thresholds to require separate presentation. As such, an additional reportable segment which consists solely of the results of Tietê is now reported as Generation – Tietê. Tietê was formerly reported within the Latin America –Generation segment. The previously disclosed Latin America – Generation segment is now reported as Generation – Latin America – Other and, with the exception of Tietê, includes the results of all remaining businesses as previously reported. All prior period results have been retrospectively revised to reflect the new segment reporting structure. The Company has increased from six to the following seven reportable segments: •        Generation – Latin America – Other; •        Generation – Tietê; •        Generation – North America; •        Generation – Europe; •        Generation – Asia; •        Utilities – Latin America; •        Utilities – North America. Corporate and Other—The Company’s Europe Utilities, Africa Utilities, Africa Generation, Wind Generation operating segments and other climate solutions and renewables projects are reported within “Corporate and Other” because they do not meet the criteria to allow for aggregation with another operating segment or the quantitative thresholds that would require separate disclosure under segment reporting accounting guidance. None of these operating segments are currently material to our presentation of reportable segments, individually or in the aggregate. AES Solar and certain other unconsolidated businesses are accounted for using the equity method of accounting; therefore, their operating results are included in “Net Equity in Earnings of Affiliates” on the face of the Consolidated Statements of Operations, not in revenue or gross margin. “Corporate and Other” also includes corporate overhead costs which are not directly associated with the operations of our seven reportable segments and other intercompany charges such as self-insurance premiums which are fully eliminated in consolidation.
