Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Our effective income tax rate was 30.6% and 22.9% for the three months ended June 30, 2020 and 2019, respectively. The increase from the second quarter of 2019 was primarily due to the increase in current quarter accruals of reserves for uncertain tax positions and higher tax impact on unremitted foreign earnings and profits, partially offset by the beneficial impact of changes in valuation allowance related to research and development (R&D) credits, pretax mix across jurisdictions with disparate tax rates and the international provisions from the U.S. tax reform enacted in 2017. Our effective income tax rate was 26.1% and 18.5% for the six months ended June 30, 2020 and 2019, respectively. The increase from the first half of 2019 was primarily due to the increase in current quarter accruals of reserves for uncertain tax positions, the decrease in excess tax deductions on stock-based compensation and higher tax impact on unremitted foreign earnings and profits, partially offset by the beneficial impact of changes in valuation allowance related to R&D credits and pretax mix across jurisdictions with disparate tax rates. The total amount of unrecognized tax benefits as of June 30, 2020 was $14.2 million, of which $13.8 million would affect our effective tax rate if recognized. We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of June 30, 2020, we had $0.9 million accrued for the payment of interest. We are subject to taxation in the U.S. and various state and foreign jurisdictions. With few exceptions, we are no longer subject to examinations by tax authorities for years prior to 2015.
