The statutory federal income tax rate for fiscal 2018 is a blended rate due to the Tax Act. See Note 1.

The effective income tax rate for fiscal 2018 is lower than fiscal 2017 primarily due to $22 million in excess tax benefits in the current year as well as the effect of the federal rate change of $17 million due to the Tax Act. The excess tax benefits are related to employee share-based compensation as a result of the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, see “Accounting Standards Updates” in Note 1. The effective income tax rate in fiscal 2017 was lower than fiscal 2016 primarily due increased research and development credits in fiscal 2017.
Deferred income taxes are recorded for differences in the basis of assets and liabilities for financial reporting purposes and tax reporting purposes. Deferred tax assets (liabilities) were comprised of:

Unrecognized tax benefits for fiscal 2018 of $6 million are presented as other long-term liabilities and $1 million is classified as a reduction to the corresponding deferred tax asset, presented in other assets on the consolidated balance sheets. Unrecognized tax benefits for fiscal 2017 of $4 million are presented as other long-term liabilities and $1 million is classified as a reduction to the corresponding deferred tax asset. We do not believe that it is reasonably possible that the unrecognized tax benefits will materially change in the next 12 months.
For the periods presented, there was not a significant amount of accrued interest and penalties recognized in the consolidated balance sheets and statements of income and comprehensive income. Tax interest and tax penalties, if any, would be included in income tax expense.
Beginning with fiscal 2014, the Company has filed income tax returns in the U.S. and various state jurisdictions, which may be subject to routine compliance reviews by the IRS and other taxing authorities. While the Company believes it has adequate accruals for uncertain tax positions, the tax authorities may determine that the Company owes taxes in excess of recorded accruals or the recorded accruals may be in excess of the final settlement amounts agreed to by tax authorities. The Company’s tax returns for fiscal years 2014 through 2017 remain subject to examination by the IRS and various other tax jurisdictions. The Company is not responsible for any tax items on operations before the separation except for Scitor’s tax returns that remain subject to examination by the U.S. Internal Revenue Service and various other tax jurisdictions from 2005 through the acquisition.
In fiscal 2016 the Company acquired all of Scitor’s stock in a transaction taxable to the selling shareholders. The Company inherited Scitor’s historical tax basis in deductible goodwill, certain other intangible assets, and operating loss carryforwards. At the date of the acquisition, the tax deductible goodwill was $136 million and the tax deductible identified intangible assets were $163 million. The Company inherited a federal and state net operating loss of $90 million subject to Internal Revenue Code Section 382 limitations. The Company expects to utilize these losses completely by fiscal 2020. The net operating losses will begin to expire in fiscal 2027.
The Company has $6 million of state credit carryforwards that will begin to expire in fiscal 2026.
