Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The following table presents Income tax expense (benefit) and the effective tax rate:
| Three Months Ended June 30, |  |  |  | Six Months Ended June 30, |  |
| 2020 |  | 2019 |  | 2020 |  | 2019
| (Dollars in thousands) |  |  |  |  |  |
Income tax expense (benefit) | $ | 39,169 |  |  | $ | 42,960 |  |  | $ | (104,134) |  |  | $ | 70,257 |
Effective tax rate | 20 | % |  | 23 | % |  | (27) | % |  | 18 | %
The effective tax rate for each of the periods in the table above differed from the statutory federal rate of 21% due to a lower foreign effective tax rate and excess tax benefits related to stock-based compensation, offset by state income taxes and U.S. taxes on foreign earnings, net of foreign tax credits. Additionally, during the six months ended June 30, 2020, the Company remeasured its previously unrecognized income tax benefits relating to the worthless stock deduction taken in 2013. The remeasurement, which resulted in the recognition of a $167.8 million benefit in the first quarter, was based on Internal Revenue Service (“IRS”) written confirmation indicating no examination adjustment would be proposed. Notwithstanding this written confirmation, the Company’s U.S. federal income tax returns remain under examination by the IRS for 2010 through 2014. The timing of completion and ultimate outcome of the audits remains uncertain and it is reasonably possible that during the next 12 months, the Company’s unrecognized tax benefits may change further as a result of IRS audits.
