Income Taxes

The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions.  The Internal Revenue Service (the “IRS”) has completed examinations of the Company’s U.S. income tax returns or the statute of limitations has passed on returns for the years through 2010. The Company’s 2011 through 2015 U.S. income tax returns are currently under examination by the IRS, and the IRS has sought to disallow research credits in the total amount of $5.7 million on the Company’s 2011 through 2015 U.S. income tax returns.  The Company has exhausted all administrative appeals and formal mediation and has filed suit to resolve this dispute. A court date in November 2019 has been set by the U.S. Tax Court for the 2011

through 2013 returns. The Company believes the research credits taken are appropriate and intends to vigorously defend its position. An amount of adjustment, if any, and the timing of such adjustment are not reasonably possible to estimate at this time. The total amount of research credits taken or expected to be taken in the Company’s income tax returns for 2011 through June 30, 2019 is approximately $11.5 million.

Under the provisions of the ASC Subtopic 740-10-25, Income Taxes - Recognition, the Company had an unrecognized tax benefit of $3.4 million (excluding $0.5 million of interest) as of June 30, 2019.

The Company’s effective tax rate was 26.0% and 23.4% for the three and six months ended June 30, 2019, respectively, compared to 26.2% and 24.9% for the three and six months ended June 30, 2018, respectively. The effective tax rate decreased during the six months ended June 30, 2019 primarily due to the increase in tax benefits recognized related to share-based compensation deductions compared to the prior year. As of June 30, 2019, the Company’s net non-current deferred tax liability was $11.3 million. Deferred tax liabilities primarily relate to goodwill, other intangibles, fixed assets, prepaid expenses and issuance of the Notes. Net non-current deferred tax liabilities are recorded in “Other non-current liabilities” on the Condensed Consolidated Balance Sheets as of June 30, 2019 (unaudited) and December 31, 2018.

In general, it is the Company’s practice and intention to reinvest the earnings of the Company’s foreign subsidiaries in those operations. However, during 2017, the Company determined that as a result of changes in the business and macroeconomic environment, the foreign earnings of the Company’s Chinese subsidiary were no longer permanently reinvested. The Company may repatriate available earnings from time to time. Management intends to continue to permanently reinvest all other remaining current and prior earnings in its other foreign subsidiaries.

Excluding China, foreign unremitted earnings of entities not included in the United States tax return have been included in the consolidated financial statements without giving effect to the United States taxes that may be payable on distribution to the United States because it is not anticipated such earnings will be remitted to the United States. Under current applicable tax laws, if the Company elects to remit some or all of the funds it has designated as indefinitely reinvested outside the United States, the amount remitted would be subject to non-U.S. withholding taxes. As of June 30, 2019, the aggregate unremitted earnings of the Company’s foreign subsidiaries for which a deferred income tax liability has not been recorded was approximately $10.1 million, and the unrecognized deferred tax liability on unremitted earnings was approximately $0.5 million.
