7.   Income Taxes. Our provision for income taxes for the three-month periods ended September 30, 2020 and 2019 was a tax expense (benefit) of approximately $0.8 million and $(2.3) million, respectively, which resulted in an effective tax rate of (37.7)% and 40.3%, respectively. Our provision for income taxes for the nine-month periods ended September 30, 2020 and 2019 was a tax expense (benefit) of approximately $(1.3) million and $0.5 million, respectively, which resulted in an effective tax rate of 4.7% and 4.9%, respectively. The income tax expense and corresponding decrease in the effective tax rate for the three-month period ended September 30, 2020, when compared to the prior-year period, was due to a change in the jurisdictional mix of earnings. The income tax benefit and corresponding decrease in the effective tax rate for the nine-month period ended September 30, 2020, 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 for both the three and nine-month periods ended September 30, 2020 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 and certain legal settlements).
