Income Taxes [Abstract]
Income Taxes	Note 15. Income Taxes The total amount of unrecognized tax benefits as of June 30, 2011, was $513 million, of which $38 million would affect the Company’s effective tax rate if recognized. In July 2011, the IRS audit for tax years 2004 through 2006 was closed resulting in a refund of approximately $40 million. As a result of the closing of these years, the Company expects to record a reversal of unrecognized tax benefits of approximately $400 million in the third quarter of 2011. The Company is continually under audit by various taxing jurisdictions, and as a result, it is possible that the remaining amount of unrecognized tax benefits could change within the next 12 months. An estimate of the range of the possible change, other than as previously disclosed above cannot be made until tax positions are further developed or examinations close. The Company recognizes interest and penalties related to unrecognized tax benefits through income tax expense. As of June 30, 2011, the Company had $92 million accrued for the payment of interest and no accrued penalties. The Company is subject to taxation in the U.S. federal jurisdiction, as well as various state and foreign jurisdictions. As of June 30, 2011, the Company is no longer subject to examination by U.S. federal taxing authorities for years prior to 2004 and to examination by any U.S. state taxing authority prior to 1998. As mentioned above, U.S. federal tax years 2004 through 2006 were closed in July 2011. All subsequent periods remain eligible for examination. In the significant foreign jurisdictions in which the Company operates, the Company is no longer subject to examination by the relevant taxing authorities for any years prior to 2001.
