Income Taxes

The Company’s effective tax rate was 25.5% and 25.6% for the three months ended September 30, 2021 and 2020, respectively. The decrease in the effective tax rate was due primarily to an increase in untaxed income attributable to noncontrolling interests, release of a valuation allowance on foreign tax credits utilized on the 2020 federal return, and a change in jurisdictional earnings, partially offset by a write down of a foreign tax receivable.  The Company’s effective tax rate for the nine months ended September 30, 2021 and September 30, 2020 was 25.8% and 26.4%. The decrease in effective tax rate was due primarily to an increase in untaxed income attributed to noncontrolling interests, release of a valuation allowance on foreign tax credits utilized on the 2020 federal return, and a change in jurisdictional earnings, partially offset by a write down of a foreign tax receivable. The difference between the effective tax rate and the statutory U.S. Federal income tax rate of 21.0% for the three and nine months ended September 30, 2021 primarily relates to state income taxes, a valuation allowance recorded against foreign tax credit carryovers, and a write down of the foreign tax receivable, partially offset by tax benefits related to untaxed income attributable to noncontrolling interests and federal research tax credits.  

As of September 30, 2021, the Company’s deferred tax assets were subject to a valuation allowance of $32.0 million primarily related to foreign net operating loss carryforwards, foreign tax credit carryforwards, and capital losses that the Company has determined are not more-likely-than-not to be realized. The factors used to assess the likelihood of realization include:  the past performance of the entities, forecasts of future taxable income, future reversals of existing taxable temporary differences, and available tax planning strategies that could be implemented to realize the deferred tax assets. The ability or failure to achieve the forecasted taxable income in these entities could affect the ultimate realization of deferred tax assets. 

As of September 30, 2021 and December 31, 2020, the liability for income taxes associated with uncertain tax positions was $17.6 million and $16.4 million, respectively.  It is reasonably possible that the Company may realize a decrease in our uncertain tax positions of approximately $0.2 million during the next 12 months as a result of various tax audits and closing tax years.

Although the Company believes its reserves for its tax positions are reasonable, the final outcome of tax audits could be materially different, both favorably and unfavorably.  It is reasonably possible that certain audits may conclude in the next 12 months and that the unrecognized tax benefits the Company has recorded in relation to these tax years may change compared to the liabilities recorded for these periods. However, it is not currently possible to estimate the amount, if any, of such change.
