Income Taxes

6.   Income Taxes. Our provision for income taxes for the three-month periods ended March 31, 2022 and 2021 was a tax expense of $3.6 million and $1.7 million, respectively, which resulted in an effective tax rate of 25.6% and 13.7%, respectively. The increase in the income tax expense and the corresponding change in the effective income tax rate for the three-month period ended March 31, 2022, when compared to the prior-year period, was primarily due to decreased benefit from discrete items such as share-based compensation. Our effective tax rate differs from the U.S. statutory rate primarily due to the impact of global intangible low-taxed income (“GILTI”) inclusions, state income taxes, foreign taxes, other non-deductible permanent items and discrete items (such as share-based compensation).
