Income Taxes

The Company recorded an income tax provision of $2.9 million and $4.2 million for the three months ended September 30, 2018 and 2017, respectively, and a provision of $1.9 million and $11.0 million for the nine months ended September 30, 2018 and 2017, respectively. In general, our effective tax rate differs from the federal income tax rate due to the effects of foreign tax rate differences, foreign withholding taxes, changes in unrecognized tax benefits, changes in valuation allowance, deferred tax expense on amortization of indefinite-lived intangible assets and effects of permanent differences.

Due to uncertainty as to the realization of benefits from the Company's U.S. and certain international net deferred tax assets, including net operating loss carryforwards, the Company has a full valuation allowance reserved against such net deferred tax assets. The Company intends to continue to maintain a full valuation allowance on certain jurisdictions’ net deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances.

As of September 30, 2018 and December 31, 2017, the liability for income taxes associated with uncertain tax positions was $8.4 million and $8.7 million, respectively. As of September 30, 2018 and December 31, 2017, the Company had accrued $6.1 million and $6.5 million, respectively, of interest and penalties related to uncertain tax positions. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions may significantly decrease within the next 12 months. This change may be the result of settlement of ongoing foreign audits.

In December, 2017, the United States enacted new U.S. federal tax legislation known as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act significantly revises the U.S. corporate income tax regime by, among other things, lowering corporate income tax rates, in general limiting interest expense to 30% of taxable income, implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As of September 30, 2018, we do not expect a material tax impact as a result of the Tax Act due to a current year loss and a full valuation allowance against our deferred tax assets.

We have estimated the impacts of the Tax Act in accordance with SAB 118. As of September 30, 2018, we have estimated an income tax benefit impact of $4.6 million for the year ended December 31, 2017, reflecting the revaluation of our net deferred tax liability based on a U.S. federal tax rate of 21 percent, and are expecting no tax impact related to the estimated repatriation toll charge of $17.2 million, which was fully offset by the net operating loss generated in 2017. As of September 30, 2018, our management is continuing to evaluate the effects of the Tax Act provisions, but we do not expect a material positive or negative impact to our 2017 tax positions.
