Income Taxes

9. Income Taxes

The income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate as adjusted for discrete items arising in that quarter. The effective income tax rate was (0.1)% and (0.4)% for the three months ended April 30, 2022 and 2021, respectively. The effective tax rate differs from the U.S. statutory rate primarily due to the full valuation allowances on the Company’s net domestic deferred tax assets and impact of foreign tax rate differential.
