DFIN 2017 Annual Report

The ongoing effects of the Tax Act and the refinement of provisional estimates could make our results difficult to predict. Our effective tax rate may fluctuate in the future as a result of the Tax Act, which was enacted on December 22, 2017. The Tax Act introduces significant changes to U.S. income tax law that will have a meaningful impact on our provision for income taxes. Accounting for the income tax effects of the Tax Act requires significant judgments and estimates in the interpretation and calculations of the provisions of the Tax Act. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, we made reasonable estimates of the effects and recorded provisional amounts in our financial statements for the year ended December 31, 2017. The U.S. Treasury Department, the IRS, and other standard-setting bodies may issue guidance on how the provisions of the Tax Act will be applied or otherwise administered that may be different from our interpretation. As we collect and prepare necessary data, and interpret the Tax Act and any additional guidance issued by the IRS or other standard-setting bodies, we may make adjustments to the provisional amounts that could materially affect our financial position and results of operations as well as our effective tax rate in the period in which the adjustments are made.
