The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. The amount of unrecognized tax benefits for uncertain tax positions was $25.6 million as of September 30, 2017 and $24.3 million as of December 31, 2016, excluding related liabilities for interest and penalties of $1.5 million and $1.9 million as of September 30, 2017 and December 31, 2016, respectively. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $1.4 million, due to the settlement of various audits and the expiration of statutes of limitation.
