| Income Taxes | Note 11—Income Taxes The effective income tax rates were 32% and 31% for the three and six months ended March 31, 2015, respectively, and 22% and 27% for the three and six months ended March 31, 2014, respectively. The effective tax rates for the three and six months ended March 31, 2015 differ from the effective tax rates in the same periods in fiscal 2014 primarily due to the absence of a one-time $201 million tax benefit recorded in the second quarter of fiscal 2014 related to a deduction for U.S. domestic production activities, of which, $184 million related to prior fiscal years and $17 million related to the first quarter of fiscal 2014. During the three and six months ended March 31, 2015, there were no significant changes in total unrecognized tax benefits or interest and penalties related to uncertain tax positions. The Company’s tax filings are subject to examination by the U.S. federal, state and foreign tax authorities. The timing and outcome of the final resolutions of the various ongoing income tax examinations are highly uncertain. It is reasonably possible that in the next six to twelve months the Company will recognize up to $300 million of tax benefits, resulting from the decrease in the current amount of unrecognized tax benefits. |
