Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE N – INCOME TAXES Income tax expense for the three and six months ended September 30, 2012 was $105 million and $235 million, respectively, compared with the three and six months ended September 30, 2011 of $91 million and $196 million, respectively. For the three and six months ended September 30, 2011, the Company recognized a net tax benefit of $15 million and $18 million, respectively, resulting primarily from the recognition of tax benefits related to an investment in a foreign subsidiary. In April 2011, the U.S. Internal Revenue Service (IRS) completed its examination of the Company’s federal income tax returns for the tax years ended March 31, 2005, 2006 and 2007 and issued a report of its findings in connection with the examination. The Company disagrees with certain proposed adjustments in the report and is vigorously disputing these matters through the IRS appellate process. The IRS is also examining the Company’s federal income tax returns for the tax years ended March 31, 2008, 2009 and 2010. While it is difficult to predict the final outcome or the timing of resolution of any particular tax matter, the Company believes that its financial statements reflect the probable outcome of uncertain tax positions. The Company may adjust these uncertain tax positions, as well as any related interest or penalties, in light of changing facts and circumstances, including the settlement of income tax audits and the expirations of statutes of limitation. To the extent a settlement differs from the amounts previously reserved, that difference generally would be recognized as a component of income tax expense in the period of resolution. Although the timing of the resolution of income tax examinations is highly uncertain, it is reasonably possible that settlements, payments and new information in the next 12 months related to certain federal, foreign and state tax issues may result in changes to the Company’s uncertain tax positions, including issues involving taxation of international operations, certain state tax issues and other matters. The Company believes that such reasonably possible changes within the next 12 months may reduce the balance of unrecognized tax benefits, net of the effects of refunds and other affirmative claims, by an amount up to $200 million. The Company’s effective income tax rate, excluding the impact of discrete items, for the six months ended September 30, 2012 and 2011 was 33.0% and 32.4%, respectively. Legislative changes in tax laws, the outcome of tax audits and any other changes in potential tax liabilities may result in additional tax expense or benefit in fiscal year 2013, which are not considered in the Company’s estimated annual effective tax rate. While the Company does not currently view any such items as individually material to the results of the Company’s consolidated financial position or results of operations, the impact of certain items may yield additional tax expense or benefit in the remaining quarters of fiscal year 2013 and the Company is anticipating a fiscal year 2013 effective tax rate of approximately 30% to 31%.
