Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION General Information The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information or footnotes required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in the Financial Supplement of our Form 10-K for the year ended December 31, 2011. Management believes that the accompanying Consolidated Financial Statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. We have eliminated all material intercompany transactions in our Consolidated Financial Statements. We do not consolidate the financial statements of any company in which we have an ownership interest of 50% or less unless we control that company. We did not control any company in which we had an ownership interest of 50% or less for any period presented in our Consolidated Financial Statements. Certain prior year amounts in the Consolidated Financial Statements have been reclassified to conform with current year presentation. New Accounting Pronouncements On January 1, 2012, we adopted the provisions of an amendment to Accounting Standards Codification ("ASC") 220, “Comprehensive Income.” This amendment requires companies to present the components of net income and other comprehensive income either as one continuous statement or as two consecutive statements. It eliminated the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. In addition, in December 2011, the FASB issued an amendment to this accounting standard which defers the requirement to present components of reclassifications of other comprehensive income on the face of the income statement. The amendments affect only the display of information and do not change existing recognition and measurement requirements in our Consolidated Financial Statements. On July 1, 2011, we adopted the provisions of an amendment to ASC 310 “Receivables." This amendment provides guidance for determining whether a restructuring of a debt constitutes a troubled debt restructuring ("TDR"). This amendment requires that a restructuring be classified as a TDR when it is both a concession and the debtor is experiencing financial difficulties. Additionally, the amendment clarifies the guidance on a creditor's evaluation of whether it has granted a concession. This amendment did not have a material impact on our Consolidated Financial Statements. Issued but not yet effective accounting pronouncements are not expected to have a material impact on our Consolidated Financial Statements.
