Income Tax Disclosure [Abstract] |
Income Taxes | (12) Income Taxes: Income tax provisions for interim periods are based on estimated effective annual income tax rates and include federal and state income taxes. On December 22, 2017, the U.S. federal government enacted comprehensive tax legislation with the Tax Cuts and Jobs Act, or Tax Reform, which makes broad and complex changes to the U.S. tax code. Tax Reform significantly revised the corporate federal income tax by, among other things, lowering the corporate federal income tax rate, limiting various deductions, and repealing the domestic manufacturing deduction. We expect to see net benefits from the lower federal tax rate, although there are offsetting effects from other components of Tax Reform. Tax Reform reduced the U.S. federal statutory income tax rate from 35% to 21% generally effective for tax years beginning on or after January 1, 2018. Our U.S. federal statutory tax rate will be 21.0% in fiscal 2019. On December 22, 2017, the SEC issued Staff Accounting Bulletin 118, or SAB118, that provides additional guidance allowing companies to use a measurement period, similar to that used in business combinations, to account for the impacts of Tax Reform in their financial statements. In accordance with SAB 118, to the extent that a company’s accounting for certain income tax effects of the Tax Reform is incomplete, but the company is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. We have accounted for the impacts of Tax Reform to the extent a reasonable estimate could be made during the fiscal year ended April 30, 2019. We will continue to refine our estimates throughout the measurement period or until the accounting is complete. We estimated the impact of Tax Reform, based on currently available information and interpretations of the law, to be a benefit to us of $8.7 million, which was included in our fiscal 2018 tax benefit. The majority of the tax benefit is due to remeasurement of deferred tax assets and liabilities at lower enacted corporate federal tax rates, which did not have a cash impact on fiscal 2018. The actual impact of Tax Reform may differ from this estimate, possibly materially, because of, among other things, changes in interpretations and assumptions we have made, guidance that may be issued, and actions we may take as a result of Tax Reform. The income tax provisions represented effective tax rates of 33.3% and 49.6% for the three months ended July 31, 2018 and 2017, respectively.
