On December 22, 2017, U.S. tax legislation was enacted that made significant changes to many elements of the U.S. federal Internal Revenue Code. Due to the recent enactment of this tax legislation and expected further rulemaking and future regulatory guidance, a comprehensive estimate of the overall tax impact to the Company's financial position, results of operations and cash flows cannot be made at this time. However, at this time, the Company does anticipate this tax legislation will result in a discrete tax impact related to revaluing the Company's U.S. federal deferred tax assets and liabilities, a discrete tax impact associated with including incremental earnings from the Company's non-U.S. entities in its U.S. federal income tax base and a change to the Company’s fiscal 2018 estimated annual tax rate due to the statutory corporate tax rate reduction. These changes will impact Deferred income tax and Other non-current liabilities in the Consolidated Condensed Balance Sheet.
