Income Tax Disclosure [Abstract]
PROVISION FOR INCOME TAXES	PROVISION FOR INCOME TAXES: U.S. Tax Reform The Tax Cuts and Jobs Act (Tax Act) was enacted on December 22, 2017. The Act reduced the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The Company has not completed the accounting for the tax effects of enactment of the Tax Act; however, in certain cases, as described below, the Company has made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax. In other cases, the Company has not been able to make a reasonable estimate. The Company has not recorded any additional measurement-period adjustments during the nine months ended September 30, 2018. However, the Company continues to evaluate the provisions of the Tax Act, including the recently issued IRS notices, and expects to complete the accounting within the prescribed measurement period. The SEC staff issued Staff Accounting Bulletin 118 (SAB 118), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The items for which the Company was able to determine a reasonable estimate includes a provisional one-time transition tax of $35.3 million, which was included as a component of the income tax provision for the year-ended December 31, 2017. This one-time transition tax was based on the Company’s estimated total post-1986 earnings and profits (E&P) previously deferred from U.S. income taxes. As of December 31, 2017, the Company had no additional undistributed foreign earnings that would be subject to the transition tax; although, this amount may change upon finalization of the total post-1986 foreign E&P balances and local foreign tax returns filed in the current year. The Company also re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in future periods, which is generally 21%. In the year ended December 31, 2017, the Company recorded a provisional amount of $4.9 million related to the re-measurement of the Company’s deferred tax assets and liabilities. As the Company is still analyzing certain aspects of the Tax Act and refining calculations, the measurement of these balances may potentially change or give rise to new deferred tax amounts. The Act also includes provisions for Global Intangible Low-Taxed Income (“GILTI”) wherein taxes on foreign income are imposed in excess of a deemed return on tangible assets of foreign corporations. Due to the complexity of the GILTI tax rules and lack of IRS guidance, the Company continues to evaluate this provision of the Tax Act and the application of ASC 740. The Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into the Company’s measurement of deferred taxes (the “deferred method”). The Company’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing the Company’s global income to determine whether the Company expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends on not only the Company’s current structure and estimated future results of global operations but also the Company’s intent and ability to modify the Company’s structure and/or business. The Company has not made any provisional adjustments related to potential GILTI deferred taxes in the Company’s financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI. However, the Company has included a current estimate of the 2018 GILTI impact in the computation of the annual effective tax rate. Income Taxes Income-tax expense includes a provision for federal, state and foreign taxes based on the annual estimated effective tax rate applicable to the Company and its subsidiaries, adjusted for certain discrete items which are fully recognized in the period they occur. The Company's effective tax rates for the three and nine months ended September 30, 2018, were 7.6% and 6.3%, respectively, and 2.6% and 1.2% for the corresponding periods of 2017. In the three and nine months ended September 30, 2018 and 2017, the effective tax rates for these periods were lower than the then statutory federal income-tax rates of 21% and 35%, respectively, due to the geographic distribution of the Company’s world-wide earnings in lower tax jurisdictions, federal research tax credits, as well as the recognition of excess tax benefits related to share-based payments. These benefits were offset in part by the estimated 2018 GILTI tax for both the three and nine months ended September 30, 2018. As of September 30, 2018, the Company maintained a valuation allowance on its California deferred tax assets, New Jersey deferred tax assets and a valuation allowance with respect to its deferred tax assets relating to tax credits in Canada. Determining the consolidated provision for income tax expense, income tax liabilities and deferred tax assets and liabilities involves judgment. The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates, which involves estimating current tax exposures as well as making judgments regarding the recoverability of deferred tax assets in each jurisdiction. The estimates used could differ from actual results, which may have a significant impact on operating results in future periods.

Income Taxes

Income-tax expense includes a provision for federal, state and foreign taxes based on the annual estimated effective tax rate applicable to the Company and its subsidiaries, adjusted for certain discrete items which are fully recognized in the period they occur.

The Company's effective tax rates for the three and nine months ended September 30, 2018, were 7.6% and 6.3%, respectively, and 2.6% and 1.2% for the corresponding periods of 2017. In the three and nine months ended September 30, 2018 and 2017, the effective tax rates for these periods were lower than the then statutory federal income-tax rates of 21% and 35%, respectively, due to the geographic distribution of the Company’s world-wide earnings in lower tax jurisdictions, federal research tax credits, as well as the recognition of excess tax benefits related to share-based payments. These benefits were offset in part by the estimated 2018 GILTI tax for both the three and nine months ended September 30, 2018.

As of September 30, 2018, the Company maintained a valuation allowance on its California deferred tax assets, New Jersey deferred tax assets and a valuation allowance with respect to its deferred tax assets relating to tax credits in Canada.

Determining the consolidated provision for income tax expense, income tax liabilities and deferred tax assets and liabilities involves judgment.
