Income Tax Disclosure [Abstract]

8.	Income Taxes

Provision for income tax for the three months ended March 31, 2021 was primarily due to foreign taxes. The benefit from income taxes for the three months ended March 31, 2020 was primarily due to the tax effect arising from other comprehensive income related to available-for-sale securities, partially offset by foreign taxes.

Based upon the weight of available evidence, which includes its historical operating performance, reported cumulative net losses since inception, the Company has established and continues to maintain a full valuation allowance against its deferred tax assets as it does not currently believe that realization of those assets is more likely than not.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
