Income Taxes INCOME TAXES
Our effective tax rate was 21.5 percent for the 2020 second quarter compared to 26.2 percent for the 2019 second quarter. The decrease in our effective tax rate was primarily due to the prior year tax expense incurred for U.S. tax on global intangible low-taxed income (“GILTI”) and the prior year impact of the non-tax deductible accrual for the Proposed ICO Fine.
Our effective tax rate was 27.3 percent for the 2020 first half compared to 18.7 percent for the 2019 first half. The change in our effective tax rate was primarily due to a more favorable impact from stock based compensation as a percentage of lower pre-tax book income.
We paid cash for income taxes, net of refunds, of $72 million in the 2020 first half and $241 million in the 2019 first half.
