Consolidation In this Quarterly Report the terms “AES”, “the Company”, “us” or “we” refer to the consolidated entity including its subsidiaries and affiliates. The terms “The AES Corporation”, “the Parent” or “the Parent Company” refer only to the publicly-held holding company, The AES Corporation, excluding its subsidiaries and affiliates.

(“AES Eastern Energy”), which had filed for bankruptcy protection under Chapter 11 in the U.S. Bankruptcy Court on December 30, 2011 and, effective that date, had been deconsolidated from the Company's consolidated financial statements due to the loss of control. The gain on deconsolidation of AES Eastern Energy continues to be deferred pending the resolution of bankruptcy protection proceedings.

Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income and cash flows. The results of operations for the three and six months ended June 30, 2012 are not necessarily indicative of results that may be expected for the year ending December 31, 2012.

In addition, entities are required to disclose the hierarchy level for items which are not measured at fair value in the statement of financial position, but for which fair value is required to be disclosed.

The amendment does not change what items are reported in other comprehensive income or the U.S. GAAP requirement to report the reclassification of items from other comprehensive income to net income. The Company adopted ASU No. 2011-05 on January 1, 2012 and chose to report comprehensive income in two consecutive statements by adding a new consolidated statement of comprehensive income for the three and six months ended June 30, 2012 and 2011 in these consolidated financial statements.

Typically, revenue of utility businesses meets the above criteria and would be classified as regulated revenue. Revenue that is not subject to rate regulation or is not determined by a regulator is classified as non-regulated revenue.

If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 or January 1, 2013 for the Company. Early adoption is permitted. The adoption of ASU No. 2012-02 is not expected to have a material impact on the Company's financial position, results of operations or cash flows.
