Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes In the first quarter of fiscal 2018, we recorded an income tax benefit of $0.6 million, representing an effective tax rate of (1.4)%. This tax rate reflects the impact of the comprehensive tax legislation enacted by the U.S. government on December 22, 2017, which is commonly referred to as the Tax Cuts and Jobs Act ("TCJA"). The TCJA significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. corporate tax rate from 35% to 21% effective January 1, 2018, while also repealing the deduction for domestic production activities, limiting the deductibility of certain executive compensation, implementing a territorial tax system, and imposing a one-time repatriation tax on deemed repatriated earnings of foreign subsidiaries. As we have a September 30 fiscal year-end, our U.S. federal corporate income tax rate will be blended in fiscal 2018, resulting in a statutory federal rate of approximately 24.5% (3 months at 35% and 9 months at 21%), and will be 21% for subsequent fiscal years. GAAP requires that the impact of tax legislation be recognized in the period in which the tax law was enacted. As a result of the TCJA, we reduced our deferred tax liabilities and recorded a one-time deferred tax benefit of approximately $10.1 million in the first quarter of fiscal 2018 to reflect our estimate of temporary differences in the United States that will be recovered or settled in fiscal 2018 based on the 24.5% blended corporate tax rate or based on the 21% tax rate in fiscal 2019 and beyond versus the previous enacted 35% corporate tax rate. Excluding this tax benefit, our effective tax rate in the first quarter of fiscal 2018 was 20.9%. The TCJA also imposes a one-time transition tax on deemed repatriation of historical earnings of foreign subsidiaries. We analyzed this provision of the TCJA and our related foreign earnings accumulated under legacy tax laws during the first quarter of fiscal 2018. Based on our preliminary analysis of tax earnings and profits and tax deficits at the prescribed measurement dates, we have a cumulative net tax deficit and do not believe we have any tax liability related to this tax. The one-time revaluation of our deferred tax liabilities and our estimate of the one-time transition tax on foreign earnings are both preliminary and subject to adjustment as we refine the information necessary to record the final values. The provisional amounts incorporate assumptions made based on our current interpretation of the TCJA and may change as we receive additional clarification on the implementation guidance. Additionally, in order to complete the valuation of our deferred tax liabilities, additional information related to the timing of the recovery or settlement of our deferred tax assets and liabilities and the effective tax rates (including state tax rates) that will apply needs to be obtained and analyzed. Similarly, information related to the computation of our foreign earnings and profits subject to the one-time transition tax requires further analysis before we make a final determination that we have no related liability. The U.S. Securities and Exchange Commission ("SEC") has issued rules that would allow for a measurement period of up to one year after the enactment date of the TCJA to finalize the recording of the related tax impacts. We currently anticipate finalizing and recording any resulting adjustments by the end of our current fiscal year ending September 30, 2018. During the first quarter of fiscal 2017, we adopted accounting guidance which requires excess tax benefits and deficiencies on share-based payments to be recorded as an income tax benefit or expense, respectively, in the consolidated statement of income rather than being recorded in additional paid-in capital on the consolidated balance sheet. As a result, we recognized income tax benefits of $3.2 million and $1.8 million in the first quarters of fiscal 2018 and fiscal 2017, respectively. Excluding these discrete amounts from both periods and the one-time impacts of the TCJA, the effective tax rates for the first quarters of fiscal 2018 and 2017 were 28.0% and 32.8%, respectively. We evaluate the realizability of our deferred tax assets by assessing the valuation allowance and adjust the allowance, if necessary. The factors used to assess the likelihood of realization are our forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets. The ability or failure to achieve the forecasted taxable income in the applicable taxing jurisdictions could affect the ultimate realization of deferred tax assets. Based on future operating results in certain jurisdictions, it is possible that the current valuation allowance positions of those jurisdictions could be adjusted in the next 12 months. Because of the complexity of the new Global Intangible Low-Taxed Income ("GILTI") tax rules, we continue to evaluate this provision of the TCJA and the application of Accounting Standards Codification 740, Income Taxes. Under GAAP, we are allowed to make an accounting policy choice of either: 1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the "period cost method") or 2) factoring such amounts into our measurement of our deferred taxes (the "deferred method"). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Whether we expect to have future U.S. inclusions in taxable income related to GILTI depends on not only our current structure and estimated future results of global operations, but also our intent and ability to modify our structure. We are currently in the process of analyzing our structure and, as a result, we are not yet able to reasonably estimate the effect of this provision of the TCJA. Therefore, we have not made any adjustments related to potential GILTI tax in our consolidated financial statements, and have not made a policy decision regarding whether to record deferred tax on GILTI. As of December 31, 2017 and October 1, 2017, the liability for income taxes associated with uncertain tax positions was $9.4 million and $9.3 million, respectively. These uncertain tax positions substantially relate to ongoing examinations, which are reasonably likely to be resolved within the next 12 months.
