Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The Company accounts for incomes taxes in accordance with ASC 740. The provision or benefit for income taxes is attributable to U.S. federal, state, and foreign income taxes. The Company’s effective tax rate used for interim periods is based on an estimated annual effective tax rate including the tax effect of items required to be recorded discretely in the interim periods in which those items occur. The Company’s effective tax rates for the nine months ended December 31, 2019 and December 31, 2018 were not meaningful due to the amount of pre-tax income, and income tax benefits recorded during the period. The Company's effective tax rates for the three and nine months ended December 31, 2019 were lower compared to the prior year primarily due to significant non-recurring discrete benefits related to releases of uncertain tax positions primarily due to statute lapses, non-recurring benefits associated with restructuring activities, and Microsemi integration matters. The Company's effective tax rate for the nine months ended December 31, 2019 includes a $337.0 million tax benefit related to the intra-group transfer of certain intellectual property rights, which reduced the Company's effective tax rate for the nine months ended December 31, 2019 by 322.2%. The Company's effective tax rate is different than the statutory rates in the U.S. due to foreign income taxed at different rates than the U.S., changes in uncertain tax benefit positions, changes to valuation allowances, generation of tax credits, and the impact of the Global Intangible Low-Taxed Income ("GILTI") tax in the United States. In addition, the Company has numerous tax holidays it receives related to its Thailand manufacturing operations based on its investment in property, plant and equipment in Thailand. The Company's tax holiday periods in Thailand expire at various times in the future. Microsemi was previously granted a tax holiday in Malaysia, which expired in December 2019. The Company does not expect the expiration to have a significant impact on its financial statements. The material components of foreign income taxed at a rate lower than the U.S. are earnings accrued in Thailand, Malta and Ireland. The Company files U.S. federal, U.S. state, and foreign income tax returns. For U.S. federal, and in general for U.S. state tax returns, the fiscal 2007 and later tax years remain open for examination by tax authorities. For foreign tax returns, the Company is generally no longer subject to income tax examinations for years prior to fiscal 2007. The Company records benefits for uncertain tax positions based on an assessment of whether it is more likely than not that the tax positions will be sustained based on their technical merits under currently enacted law. If this threshold is not met, no tax benefit of the uncertain tax position is recognized. If this threshold is met, the Company recognizes the largest amount of the tax benefit that is more likely than not to be realized upon ultimate settlement. The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax laws applied to the facts of each matter. The Company believes it maintains appropriate reserves to offset any potential income tax liabilities that may arise upon final resolution of matters for open tax years. If such reserve amounts ultimately prove to be unnecessary, the resulting reversal of such reserves could result in tax benefits being recorded in the period the reserves are no longer deemed necessary. If such amounts prove to be less than an ultimate assessment, a future charge to expense would be recorded in the period in which the assessment is determined.
