Income Taxes	3 Months Ended
Mar. 31, 2021
Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes. Our provision for income taxes for the three-month periods ended March 31, 2021 and 2020 was a tax expense of approximately $1.7 million and $1.2 million, respectively, which resulted in an effective tax rate of 13.7% and (58.3)%, respectively. The increase in the income tax expense and the corresponding change in the effective tax rate for the three-month period ended March 31, 2021, when compared to the prior-year period, was primarily due to a pre-tax loss during the 2020 period, as well as a change in the jurisdictional mix of earnings. 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).
