For the years ended December 31, 2022 and 2021, the effective tax rates of (13.1)% and 12.3%, respectively, differed from the federal statutory rate of 21% in the U.S. primarily due to the valuation allowance recognized against federal and state deferred tax assets in the U.S.
For the year ended December 31, 2023, the change to the effective tax rate was primarily due to increased operating losses outside of the U.S., where tax benefits are recognized and are not offset by a valuation allowance. 69 Table of Contents Management ’ s Discussion and Analysis For the years ended December 31, 2023 and 2022, the effective tax rates of 15.3% and (13.1)%, respectively, differed from the federal statutory rate of 21% in the U.S. primarily due to the valuation allowance recorded against our U.S. federal and state net deferred tax assets.
Operating Expenses The most significant components of operating expenses are personnel costs, which consist of salaries, benefits, bonuses, and stock-based compensation expenses. We also incur other non-personnel costs related to our general overhead expenses, including facility expenses, software licenses, web services, depreciation and amortization of assets unrelated to delivery of our services.

Quarterly, we review the deferred tax assets for recoverability based on historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences, the implementation of prudent and feasible tax planning strategies, and results of recent operations. The evaluation of the recoverability of deferred tax assets requires judgment in assessing future profitability.
If we demonstrate cumulative pre-tax losses in a particular jurisdiction in a three-year period, including the current and prior two years, management then considers the expected timing of the reversals of existing temporary differences, the implementation of prudent and feasible tax planning strategies, and projected future taxable income when determining if the deferred tax assets will be realized.
