Income Taxes	3 Months Ended
Jun. 30, 2017
Income Tax Disclosure [Abstract]
Income Taxes	Note 13 – Income Taxes Our effective tax rate was 37 percent for the three months ended June 30, 2017 and 38 percent for the three months ended June 30, 2016. Our provision for income taxes was $96 million for the first quarter of fiscal 2018, compared to $146 million for the same period in fiscal 2017. The decrease in the provision for income taxes for the first quarter of fiscal 2018 is consistent with the decrease in our income before tax compared to the same period in fiscal 2017. Tax-related Contingencies As of June 30, 2017, we remain under IRS examination for fiscal 2017. The IRS examination for fiscal 2016 was concluded in the first quarter of fiscal 2018. We periodically review our uncertain tax positions. Our assessment is based on many factors including any ongoing IRS audits. For the quarter ended June 30, 2017, our assessment did not result in a material change in unrecognized tax benefits. Our deferred tax assets were $1.9 billion and $1.0 billion at June 30, 2017 and March 31, 2017, and were primarily due to the deferred deduction of allowance for credit and residual value losses and federal tax loss carryforward that expires in fiscal 2038. The total deferred tax liability, net of these deferred tax assets, was $8.1 billion and $7.9 billion at June 30, 2017 and March 31, 2017, respectively. Realization with respect to the federal tax loss carryforward is dependent on generating sufficient income prior to expiration of the loss carryforward. Although realization is not assured, management believes it is more likely than not that the deferred tax assets will be realized. The amount of the deferred tax assets considered realizable could be reduced if management’s estimates change.
