Income Taxes

Note 14 – Income Taxes

Our effective income tax rate was 22.9% and 32.6% for the three months ended June 30, 2019 and 2018, respectively. The decrease from the second quarter of 2018 was primarily due to the beneficial impact of the international tax provisions from U.S. tax reform as a result of administrative guidance issued during the second half of 2018, changes in valuation allowance related to R&D credits and a lower tax impact on unremitted foreign earnings and profits. Our effective income tax rate was 18.5% and 23.2% for the six months ended June 30, 2019 and 2018, respectively. The decrease from the first half of 2018 was primarily due to the beneficial impact of the international tax provisions from U.S. tax reform as a result of administrative guidance issued during the second half of 2018 and a lower tax impact on unremitted foreign earnings and profits, partially offset by a decrease in current year release of reserves for uncertain tax positions.

The total amount of unrecognized tax benefits as of June 30, 2019 was $9.8 million, of which $9.6 million would affect our effective tax rate if recognized. It is reasonably possible that approximately $1.4 million of our unrecognized tax benefits as of June 30, 2019 will reverse within the next 12 months.

We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of June 30, 2019, we had $0.6 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 2014.
