Income Tax Disclosure [Abstract] |
INCOME TAXES: | INCOME TAX:In determining the quarterly provision for income taxes, the Company makes its best estimate of the effective income tax rate expected to be applicable for the full fiscal year. The estimated effective income tax rate for the current fiscal year is impacted by the reduction in the U.S. federal corporate income tax rate (discussed below), non-deductible stock-based compensation, state income taxes, research tax credits, losses in foreign jurisdictions, and recording of a valuation allowance on deferred taxes. In the second quarter, the Company recognized a discrete tax expense of $5.5 million in connection with establishing a valuation allowance against its deferred tax assets originating from continuing operations. State income taxes are influenced by the geographic and legal entity mix of the Company's U.S. income as well as the diversity of rules among the states. The Company does not record a tax benefit for certain foreign losses due to uncertainty of future utilization. On December 22, 2017, the U.S. enacted significant tax law changes following the passage of H.R. 1, "An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 "the Tax Act") (previously known as "The Tax Cuts and Jobs Act"). The Tax Act reduced the U.S. federal corporate income tax rate from 35% to 21%, among other provisions. We believe we have properly estimated our federal and state income tax liabilities for the impacts of the Tax Act, including provisional amounts under SAB No. 118 related to the rate change, the impact of increased bonus depreciation, and the effects on executive compensation deductions. The Tax Act may be subject to technical amendments, as well as interpretations and implementing of regulations by the Department of Treasury and Internal Revenue Service, any of which could increase or decrease one or more impacts of the legislation. As such, we will continue to analyze the effects of the Tax Act and may record adjustments to provisional amounts during the measurement period ending no later than December 31, 2018. As of September 30, 2018, we have not changed the provisional estimates recognized in fiscal 2018. Any impacts to our income tax expense as a result of additional guidance will be recorded in the period in which the guidance is issued.
