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 nondeductible stock-based compensation, state income taxes, research tax credits, and losses in foreign jurisdictions. 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. As a result of adopting ASU 2016–09, all excess tax benefits and deficiencies from stock–based compensation will be recognized as income tax benefit and expense in the Company’s Condensed Consolidated Statement of Operations in the reporting period in which they occur. This will result in increased volatility in the Company’s effective tax rate. For the three months ended June 30, 2017, the Company recognized a discrete income tax benefit of $1.5 million related to net excess tax benefits.
