Unrecognized Tax Benefits

As of September 30, 2018, we believe $0.9 million of our unrecognized tax benefits will be reduced prior to September 30, 2019 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.

Impact of the TCJA

At December 31, 2017, a provisional amount for the effects of the TCJA was recorded and resulted in a $53.4 million tax benefit to our provision for income taxes in our consolidated statement of operations. This amount consisted of a $57.7 million tax benefit due to reducing our continuing operations net deferred tax liability, a $4.6 million tax detriment due to reducing our discontinued operations deferred tax asset and a $0.3 million tax benefit due to reducing our other comprehensive income net deferred tax liability. As of September 30, 2018, our analysis of the impact of the TCJA was complete and there were no material changes to the provisional amount recorded at December 31, 2017.
