Income Tax Disclosure [Abstract] |
Income Taxes |
15. | Income Taxes
We and our subsidiaries are subject to U.S. federal income tax as well as income tax of numerous state and foreign jurisdictions. We are generally no longer subject to U.S. federal tax examinations for taxable years before 2014 and, with limited exceptions, state and foreign income tax examinations for taxable years before 2012. We recognize potential accrued interest and penalties related to unrecognized tax benefits in Income Tax Expense. In addition to the liability of $2,475 for unrecognized tax benefits as of September 30, 2017, there was approximately $426 for accrued interest and penalties. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of September 30, 2017 was $2,130. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be revised and reflected as an adjustment of the Income Tax Expense. Unrecognized tax benefits were reduced by $688 during the first nine months of 2017 as a result of the expiration of the statute of limitations in various jurisdictions and settlement with tax authorities. We are currently under examination by the Internal Revenue Service for the 2015 tax year. Although the outcome of this matter cannot currently be determined, we believe adequate provision has been made for any potential unfavorable financial statement impact. We are currently undergoing income tax examinations in various state and foreign jurisdictions covering 2014 to 2016. Although the final outcome of these examinations cannot be currently determined, we believe that we have adequate reserves with respect to these examinations.
