[1] Through the year ended December 31, 2018, foreign currency translation adjustments excluded a provision for U.S. federal and state income taxes as a result of the Company's intention to indefinitely reinvest the earnings of its international subsidiaries outside of the United States. In response to increased cash requirements in the U.S. related to the Company’s declaration of a special cash dividend and other strategic initiatives during the fourth quarter of 2019, we determined that we no longer consider certain foreign earnings to be indefinitely reinvested. The deferred income tax liability related to foreign currency translation adjustments is not material. Refer to “Note 11: Income Taxes” for further information.
