Income Tax Disclosure [Abstract] |
Income Taxes | 13. Income Taxes The year-to-date effective tax rate for the three months ended March 31, 2019 differed significantly from our statutory rate primarily due to the reduction of a valuation allowance, which was recorded to offset the tax effect of the increase in book income in the three months ended March 31, 2019, as well as the release of an unrecognized tax benefit due to the settlement of a tax audit. Unrecognized Tax Benefits As of March 31, 2019, we believe it is reasonably possible that $1.8 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to March 31, 2020 due to the settlement of audits or the expiration of statutes of limitations or both. However, due to the uncertain and complex application of the tax regulations, it is possible that the ultimate resolution of these matters may result in liabilities which could materially differ from this estimate.
