Income Taxes Income Taxes
Accounting for income taxes for interim periods generally requires the provision for income taxes to be determined by applying an estimate of the annual effective tax rate for the full fiscal year to income or loss before income taxes, adjusted for discrete items, if any, for the reporting period. The Company updates its estimate of the annual effective tax rate each quarter and records a cumulative adjustment in such period.
The Company recorded income tax expense of $0.4 million and $0.2 million for the three months ended July 31, 2022 and 2021, respectively, and $0.6 million and $0.5 million for the six months ended July 31, 2022 and 2021. Income tax expense consists primarily of income taxes in foreign jurisdictions in which the Company conducts business. Due to the Company’s history of losses in the United States, a full valuation allowance on substantially all of the Company’s deferred tax assets, including net operating loss carryforwards, research and development tax credits, capitalized research and development, and other book versus tax differences was maintained.
