Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Our income tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment. Our interim income tax provision and our interim estimate of our annual effective tax rate are influenced by several factors, including foreign losses and capital gains and losses for which related deferred tax assets are partially offset by a valuation allowance, changes in tax laws and relative changes in unrecognized tax benefits. Additionally, our effective tax rate can be affected by the amount of pre-tax income or loss. For example, the impact of discrete items and non-deductible expenses on our effective tax rate is greater when our pre-tax income or loss is lower. Our income tax provision was $3.0 million and $5.0 million for the three months ended September 30, 2020 and September 30, 2019, respectively. Our estimated effective income tax rate was 11.2% and (27.7)% for the three months ended September 30, 2020 and 2019, respectively. The variations in our effective tax rate from the U.S. federal statutory rate for the three months ended September 30, 2020, were primarily due to the increase in our valuation allowance associated with certain foreign losses, permanent book tax differences and the impact of state and local taxes, partially offset by research and experimentation credits. The variations in our effective tax rate from the U.S. federal statutory rate for the three months ended September 30, 2019 were primarily due to the change in net unrealized gains that are capital in nature and research and experimentation credits, partially offset by the impact of state and local taxes and the increase in our valuation allowance associated with certain foreign losses. Our income tax provision was $6.3 million and $12.6 million for the nine months ended September 30, 2020 and September 30, 2019, respectively. Our estimated effective income tax rate was (14.7)% and (28.2)% for the nine months ended September 30, 2020 and 2019, respectively. The variations in our effective tax rate from the U.S. federal statutory rate for the nine months ended September 30, 2020 were primarily due to the increase in our valuation allowance associated with certain foreign losses, permanent book tax differences and the impact of state and local taxes, partially offset by the change in net unrealized losses that are capital in nature and research and experimentation credits. The variations in our effective tax rate from the U.S. federal statutory rate for the nine months ended September 30, 2019 were primarily due to the change in net unrealized gains that are capital in nature and research and experimentation credits, partially offset by the impact of state and local taxes and the increase in our valuation allowance associated with certain foreign losses. Additionally, during the nine months ended September 30, 2019, we recorded additional tax expense of $2.0 million on deemed mandatory repatriation of certain deferred foreign earnings as the result of new treasury regulations. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in March 2020. The CARES Act features significant tax provisions and other measures to assist individuals and businesses impacted by the economic effects of the COVID-19 pandemic, including a five-year carryback of net operating losses, relaxation of Section 163(j) interest deduction limitations, acceleration of Alternative Minimum Tax refunds, relief for payroll tax and tax credits for employers who retain employees. These provisions did not affect our income tax provision for the three and nine months ended September 30, 2020.
