INCOME TAXES	NOTE N – INCOME TAXES Income tax expense for the three months ended September 30, 2013 was approximately $106 million and income tax benefit for the six months ended September 30, 2013 was approximately $12 million, compared with income tax expense for the three and six months ended September 30, 2012 of approximately $105 million and $235 million, respectively. For the six months ended September 30, 2013, the Company recognized a net discrete tax benefit of approximately $179 million resulting primarily from the resolutions of uncertain tax positions upon the completion of the examination of the Company's U.S. federal income tax returns for the tax years ended March 31, 2005, 2006 and 2007. The Company’s estimated annual effective tax rate, which excludes the impact of discrete items, for the six months ended September 30, 2013 and 2012 was 29.7% and 33.0%, 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 2014, 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 2014 and the Company is anticipating a fiscal year 2014 effective tax rate of approximately 14%, which includes the impact of the aforementioned completion of the examination. The completion of the examination of the Company's U.S. federal income tax returns for the tax years ended March 31, 2005, 2006 and 2007 resulted in a reduction of approximately $221 million in the Company's uncertain tax positions as disclosed in Note 15, “Income Taxes” of the Company's Form 10-K for the year ended March 31, 2013. The Company received a cash refund of approximately $70 million upon the completion of this examination.
