Income Tax Disclosure [Abstract]
Income Taxes	Uncertain Tax Positions At March 31, 2019, the Company had $46 million of unrecognized tax benefits recorded in Other liabilities. If these unrecognized tax benefits were recognized, the effective tax rate would be affected. At March 31, 2019, the Company had accrued interest and penalties of $3.2 million classified in Other liabilities. As of March 31, 2019, the Company’s aggregate provisions for uncertain tax positions, including interest and penalties, was $49.2 million associated with various tax positions asserted in various jurisdictions, none of which is individually material. The Company regularly repatriates earnings from non-U.S. subsidiaries. In the fourth quarter of 2018, the Company changed its assertion as part of its final analysis under SAB 118, consistent with the Company’s need to repatriate funds for debt repayment purposes. As the Company repatriates these funds to the U.S., they will be required to pay income taxes in certain U.S. states and applicable foreign withholding taxes during the period when such repatriation occurs. Accordingly, as of March 31, 2019, the Company had a deferred tax liability of $87.2 million for the effect of repatriating the funds to the U.S. This balance consisted of $42.8 million attributable to IFF non-U.S. subsidiaries, and $44.4 million associated with Frutarom which is still preliminary and will be refined through the purchase accounting measurement period. The Company has ongoing income tax audits and legal proceedings which are at various stages of administrative or judicial review. In addition, the Company has open tax years with various taxing jurisdictions that range primarily from 2009 to 2018. Based on currently available information, the Company does not believe the ultimate outcome of any of these tax audits and other tax positions related to open tax years, when finalized, will have a material impact on its results of operations. The Company also has other ongoing tax audits and legal proceedings that relate to indirect taxes, such as value-added taxes, sales and use taxes and property taxes, which are discussed in Note 15. Effective Tax Rate The effective tax rate for the three months ended March 31, 2019 was 17.4% compared with 18.5% for the three months ended March 31, 2018. The quarter-over-quarter decrease was largely due to a more favorable mix of earnings (including the impact of integration related costs, restructuring charges and Frutarom acquisition related costs), partially offset by higher repatriation costs, and the absence of the remeasurement of loss provisions and the release of a State valuation allowance which benefited the first quarter of 2018.
