Notes to Condensed Consolidated Financial Statements [Abstract]
Introduction of Notes to Condensed Consolidated Financial Statements	The Condensed Consolidated Financial Statements at September 30, 2011 and for the quarters and nine months ended September 30, 2011 and 2010 are unaudited, but in the opinion of management include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the results for the interim periods. Certain reclassifications have been made to the prior period amounts to conform to the current year presentation. We previously reported “Other income, net,” which included “Interest income,” as a component of “Revenues.” “Other income, net,” excluding “Interest income,” is now reflected separately, while “Interest income” is now netted with “Interest expense” for financial statement presentation. The results reported in these Condensed Consolidated Financial Statements should not necessarily be taken as indicative of results that may be expected for the entire year. The financial information included herein should be read in conjunction with the financial statements and notes in our Annual Report to Shareowners (2010 Annual Report) incorporated by reference to our Annual Report on Form 10-K for calendar year 2010 (2010 Form 10-K).

Description containing the entire organization, consolidation and basis of presentation of financial statements disclosure. May be provided in more than one note to the financial statements, as long as users are provided with an understanding of (1) the significant judgments and assumptions made by an enterprise in determining whether it must consolidate a VIE and/or disclose information about its involvement with a VIE, (2) the nature of restrictions on a consolidated VIE's assets reported by an enterprise in its statement of financial position, including the carrying amounts of such assets, (3) the nature of, and changes in, the risks associated with an enterprise's involvement with the VIE, and (4) how an enterprise's involvement with the VIE affects the enterprise's financial position, financial performance, and cash flows. Describes procedure if disclosures are provided in more than one note to the financial statements.
