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. 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 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. During the third quarter ended December 31, 2018, we finalized our analysis of the impact of the Tax Act and did not change our provisional amounts. Any impacts to our income tax expense as a result of future technical amendments, interpretations, or regulations issued by the Department of Treasury or Internal Revenue Service will be recorded in the period in which such additional guidance is issued.
