Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations International Flavors & Fragrances Inc. and its subsidiaries (the “Registrant,” “IFF,” “the Company,” “we,” “us” and “our”) is a leading creator and manufacturer of flavors and fragrances (including cosmetic active ingredients) used to impart or improve flavor or fragrance in a wide variety of consumer products. Our products are sold principally to manufacturers of perfumes and cosmetics, hair and other personal care products, soaps and detergents, cleaning products, dairy, meat and other processed foods, beverages, snacks and savory foods, sweet and baked goods, and pharmaceutical and oral care products. Fiscal Year End The Company has historically operated on a 52/53 week fiscal year generally ending on the Friday closest to the last day of the year. For ease of presentation, December 31 is used consistently throughout the financial statements and notes to represent the period-end date. The 2017, 2016 and 2015 fiscal years were 52 week periods. For the 2017 , 2016 and 2015 fiscal years, the actual closing dates were December 29, December 30 and January 1, respectively. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Actual results may ultimately differ from estimates. Principles of Consolidation The consolidated financial statements include the accounts of International Flavors & Fragrances Inc. and those of its subsidiaries. Significant intercompany balances and transactions have been eliminated. To the extent a subsidiary is not wholly owned, any related noncontrolling interest is included as a separate component of Shareholders’ Equity. Any applicable expense (income) attributable to the noncontrolling interest is included in Other expense, net in the accompanying Consolidated Statement of Income and Comprehensive Income due to its immateriality and, as such, is not presented separately. Revenue Recognition The Company recognizes revenue when the earnings process is complete. This generally occurs when (i) title and risk of loss have been transferred to the customer in accordance with the terms of sale and (ii) collection is reasonably assured. Sales are reduced, at the time revenue is recognized, for applicable discounts, rebates and sales allowances based on historical experience. Related accruals are included in Other current liabilities in the accompanying Consolidated Balance Sheet. Foreign Currency Translation The Company translates the assets and liabilities of non-U.S. subsidiaries into U.S. dollars at year-end exchange rates. Income and expense items are translated at average exchange rates during the year. Cumulative translation adjustments are shown as a separate component of Shareholders’ Equity. Research and Development Research and development (“R&D”) expenses relate to the development of new and improved flavors or fragrances, technical product support and compliance with governmental regulation. All research and development costs are expensed as incurred. Cash Equivalents Cash equivalents include highly liquid investments with maturities of three months or less at date of purchase. Accounts Receivable The Company sells certain accounts receivable on a non-recourse basis to unrelated financial institutions under “factoring” agreements that are sponsored, solely and individually, by certain customers. The Company accounts for these transactions as sale of receivables, removes the receivables sold from its financial statements, and records cash proceeds when received by the Company. The beneficial impact on cash provided by operations from participating in these programs increased approximately $7.6 million , $34.0 million and $3.4 million in 2017 , 2016 and 2015 , respectively. The cost of participating in these programs was immaterial to our results in all periods. Inventories Inventories are stated at the lower of cost (on a weighted-average basis) or market. Our inventories consisted of the following: December 31, (DOLLARS IN THOUSANDS) 2017 2016 Raw materials $ 326,140 $ 288,629 Work in process 16,431 13,792 Finished goods 306,877 289,596 Total $ 649,448 $ 592,017 Long-Lived Assets Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is calculated on a straight-line basis, principally over the following estimated useful lives: buildings and improvements, 10 to 40 years; machinery and equipment, 3 to 20 years; information technology hardware and software, 3 to 7 years; and leasehold improvements which are included in buildings and improvements, the estimated life of the improvements or the remaining term of the lease, whichever is shorter. Finite-Lived Intangible Assets Finite-lived intangible assets include customer relationships, patents, trade names, technological know-how and other intellectual property valued at acquisition and amortized on a straight-line basis over the following estimated useful lives: customer relationships, 11 - 23 years; patents, 5 - 15 years; trade names, approximately 30 years; and technological know-how, 5 - 28 years. The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their full carrying value may not be recovered. An estimate of undiscounted future cash flows produced by an asset or group of assets is compared to the carrying value to determine whether impairment exists. If assets are determined to be impaired, the loss is measured based on an estimate of fair value using various valuation techniques, including a discounted estimate of future cash flows. Goodwill Goodwill represents the difference between the total purchase price and the fair value of identifiable assets and liabilities acquired in business acquisitions. In assessing the potential for impairment of goodwill, management uses the most current actual and forecasted operating data available and current market-based assumptions in accordance with the criteria in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 350. The Company has identified four reporting units: (1) Flavors, (2) Fragrance Compounds, (3) Fragrance Ingredients and (4) Cosmetic Actives Ingredients. These reporting units were determined based on the level at which the performance is measured and reviewed by segment management. The Company performs an annual goodwill impairment test for the Flavors, Fragrance Compounds, Fragrance Ingredients and Cosmetic Actives Ingredients reporting units by assessing the fair value of the reporting units based on discounted cash flows. If a reporting unit’s carrying amount exceeds its fair value, the Company will record an impairment charge based on that difference, and the impairment charge will be limited to the amount of goodwill allocated to that reporting unit. In January 2017, the FASB issued an amendment to the Goodwill Impairment guidance which eliminates Step 2 from the goodwill impairment test. Effective fiscal year 2017, the Company adopted the new guidance and no longer performs the annual goodwill impairment test using the two-step approach. The Company completed its annual goodwill impairment test as of November 30, 2017 , which indicated no impairment of goodwill, as the estimated fair values substantially exceeded the carrying values of each of these reporting units. Income Taxes The Company accounts for taxes under the asset and liability method. Under this method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized as income in the period in which such change is enacted. Future tax benefits are recognized to the extent that the realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes may not be realized. The Company recognizes uncertain tax positions that it has taken or expects to take on a tax return. Pursuant to accounting requirements, the Company first determines whether it is “more likely than not” its tax position will be sustained if the relevant tax authority were to audit the position with full knowledge of all the relevant facts and other information. For those tax positions that meet this threshold, the Company measures the amount of tax benefit based on the largest amount of tax benefit that it has a greater than 50% chance of realizing in a final settlement with the relevant authority. Those tax positions failing to qualify for initial recognition are recognized in the first interim period in which they meet the more likely than not standard. The Company maintains a cumulative risk portfolio relating to all of its uncertainties in income taxes in order to perform this analysis, but the evaluation of its tax positions requires significant judgment and estimation in part because, in certain cases, tax law is subject to varied interpretation, and whether a tax position will ultimately be sustained may be uncertain. Interest and penalties related to unrecognized tax benefits are recognized as a component of income tax expense. U.S. Tax Reform On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) that significantly revised the U.S. tax code effective January 1, 2018 by, among other things, lowering the corporate income tax rate from a top marginal rate of 35% to a flat 21% , limiting deductibility of interest expense and performance based incentive compensation, transitioning to a territorial system and creating new taxes associated with global operations. The Tax Act impacted the Company's consolidated results of operations during the 2017 fourth quarter and is expected to continue to impact its consolidated results of operations in future periods. In particular, the transition to the new territorial tax system required the Company to record a one-time tax or “toll charge” which resulted in a provisional incremental tax expense of $100.6 million principally related to previously unremitted earnings on non-U.S. subsidiaries. The cash portion of the "toll charge" will be payable in installments over 8 years beginning in 2018. In addition, the reduction of the U.S. corporate tax rate resulted in a provisional net deferred tax expense of $38.6 million related to the remeasurement of net deferred tax assets as a result of the reduction in the corporate income tax rate. Given the significant complexity of the Tax Act, anticipated guidance from the U.S. Treasury about implementing the Tax Act and the potential for additional guidance from the SEC or the FASB, the Company’s provisional charge may be adjusted during 2018 and is expected to be finalized no later than the fourth quarter of 2018. Other provisions of the Tax Act that impact future tax years are still being assessed. Any material revisions in the Company's computations could adversely affect its cash flows and results of operations. Retirement Benefits Current service costs of retirement plans and postretirement health care and life insurance benefits are accrued. Prior service costs resulting from plan improvements are amortized over periods ranging from 10 to 20 years. Financial Instruments Derivative financial instruments are used to manage interest and foreign currency exposures. The gain or loss on the hedging instrument is recorded in earnings at the same time as the transaction being hedged is recorded in earnings. The associated asset or liability related to the open hedge instrument is recorded in Prepaid expenses and Other current assets or Other current liabilities, as applicable. The Company records all derivative financial instruments on the balance sheet at fair value. Changes in a derivative’s fair value are recognized in earnings unless specific hedge criteria are met. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in Net income. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in Accumulated other comprehensive income ("AOCI") in the accompanying Consolidated Balance Sheet and are subsequently recognized in Net income when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges, if any, are recognized as a charge or credit to earnings. Software Costs The Company capitalizes direct internal and external development costs for certain significant projects associated with internal-use software and amortizes these costs over 7 years. Neither preliminary evaluation costs nor costs associated with the software after implementation are capitalized. Costs related to projects that are not significant are expensed as incurred. Shipping and Handling Costs Net sales include shipping and handling charges billed to customers. Cost of goods sold includes all costs incurred in connection with shipping and handling. Net Income Per Share Net income per share is based on the weighted average number of shares outstanding. A reconciliation of shares used in the computations of basic and diluted net income per share is as follows: December 31, (SHARES IN THOUSANDS) 2017 2016 2015 Basic 79,070 79,648 80,449 Assumed dilution under stock plans 300 333 442 Diluted 79,370 79,981 80,891 An immaterial amount of Stock-Settled Appreciation Rights (“SSARs”) were excluded from the computation of diluted net income per share at December 31, 2017 and 2016 . There were no stock options or SSARs excluded from the computation in 2015 . The Company has issued shares of Purchased Restricted Stock ("PRS") and Purchased Restricted Stock Units (“PRSUs”) which contain nonforfeitable rights to dividends and thus are considered participating securities which are required to be included in the computation of basic and diluted earnings per share pursuant to the two-class method. The two-class method was not presented since the difference between basic and diluted net income per share for both common shareholders, PRS and PRSU holders was less than $0.01 per share for each year and the number of PRS and PRSUs outstanding as of December 31, 2017 , 2016 and 2015 was immaterial. Net income allocated to such PRS and PRSUs during 2017 , 2016 and 2015 was approximately $1.0 million , $1.0 million and $2.0 million , respectively. Stock-Based Compensation Compensation cost of all stock-based awards is measured at fair value on the date of grant and recognized over the service period for which awards are expected to vest. The cost of such stock-based awards is principally recognized on a straight-line attribution basis over their respective vesting periods, net of estimated forfeitures. Financing Costs Costs incurred in the issuance of debt are deferred and amortized as part of interest expense over the stated life of the applicable debt instrument. Unamortized deferred financing costs relating to senior debt are presented as a reduction in the amount of debt outstanding on the Consolidated Balance Sheet. Unamortized deferred financing costs relating to the revolving credit facility are recorded in Other assets on the Consolidated Balance Sheet. Recent Accounting Pronouncements In February 2018, FASB issued amendments to the Income Statement - Reporting Comprehensive Income guidance which allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act, in addition to requiring certain disclosures about stranded tax effects. This guidance is effective for periods beginning after December 15, 2018, with an election to adopt early. The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In August 2017, FASB issued amendments to the Derivatives and Hedging guidance which eliminates the requirement to separately measure and present hedge ineffectiveness and aligns the presentation of hedge gains and losses with the underlying hedge item. This guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The amended presentation and disclosure requirements should be applied prospectively while the amendments to cash flow and net investment hedge relationships should be applied on a modified retrospective basis . The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In May 2017, the FASB issued amendments to the Compensation - Stock Compensation guidance which clarifies changes to the terms or conditions of a share-based payment award that require an entity to apply modification accounting. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted. The Company does not expect this guidance to have an impact on its Consolidated Financial Statements as it is not the Company's practice to modify the terms or conditions of a share-based payment award after it has been granted. In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires employers who present a measure of operating income in their statement of income to include only the service cost component of net periodic pension cost and postretirement costs in operating expenses. This guidance is effective, and should be applied retrospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The Company will adopt this standard on January 1, 2018, and expects the impact that this guidance will have on its Consolidated Statement of Comprehensive Income will be an increase in operating expenses of approximately $30 million and $15 million for the fiscal years 2017 and 2016, respectively. There will be no impact to Net income or Net Income per share in either period. The new guidance also limits the amount of net periodic benefit cost eligible for capitalization to assets. The new guidance permits only the service cost component of net periodic benefit cost to be eligible for capitalization. In January 2017, the FASB issued amendments to the Business Combination guidance which clarifies the definition of a business in order to assist companies when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance will be effective prospectively for annual and interim periods beginning after December 15, 2017. The Company will apply this guidance for transactions occurring after the effective date. In October 2016, the FASB issued authoritative guidance which allows for the immediate recognition of current and deferred income tax impact on intra-entity asset transfers, excluding inventory. The Company adopted this guidance in the first quarter of fiscal year 2017 and accordingly, recorded a cumulative-effect adjustment to Retained earnings that reduced Other assets and adjusted Deferred income taxes by a net amount of approximately $34 million . In August 2016, the FASB issued authoritative guidance which requires changes to the classification of certain activities within the statement of cash flows. This guidance will be effective for annual and interim periods beginning after December 15, 2017. Early adoption will be permitted for all entities. The Company does not expect this adoption to have a significant impact on its Consolidated Statement of Cash Flows. In June 2016, the FASB issued authoritative guidance which requires issuers to measure expected credit losses for financial assets based on historical experience, current conditions and reasonable and supportable forecasts. As such, an entity will use forward-looking information to estimate credit losses. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements, but does not expect this guidance to have a material impact on its consolidated financial statements. In March 2016, the FASB issued authoritative guidance which requires changes to several aspects of the accounting for share-based payment transactions, including the treatment of income tax consequences, classification of awards as either equity or liabilities, and classification of certain items on the statement of cash flows. This guidance was effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017. The standard requires that employee taxes paid when an employer withholds shares be presented in the Consolidated Statement of Cash Flows as a financing activity instead of an operating activity. The Company adopted this change retrospectively. The adoption resulted in an $11.8 million , $13.4 million and $22.9 million reclassification from Net cash provided by operating activities to Net cash provided by financing activities on the Consolidated Statement of Cash Flows as of December 31, 2017, 2016 and 2015, respectively. In addition, the standard requires that excess tax benefits presented in the Consolidated Statement of Cash Flows be classified as an operating activity instead of a financing activity. The Company adopted this change retrospectively. The adoption resulted in a $3.3 million , $4.7 million and $12.1 million reclassification from Net cash provided by financing activities to Net cash provided by operating activities on the Consolidated Statement of Cash Flows as of December 31, 2017, 2016 and 2015, respectively. The standard also requires all excess tax benefits/deficiencies be recognized as income tax expense/benefit in the Consolidated Statement of Comprehensive Income. This guidance has been applied prospectively. This change resulted in a $3.3 million benefit to income tax expense for the year ended December 31, 2017. For 2016, benefits of $5.3 million were recognized in equity. Additionally, the standard allows the Company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to be forfeited or account for forfeitures as they occur. The Company has elected to continue to account for forfeitures using an estimate of awards expected to be forfeited. In February 2016, the FASB issued authoritative guidance which requires changes to the accounting for leases. The new guidance establishes a new lease accounting model, that requires entities to record assets and liabilities related to leases on the balance sheet for certain types of leases. The guidance will be effective for annual and interim periods beginning after December 15, 2018. The Company expects to adopt this guidance effective December 30, 2018 and that the adoption of this guidance will result in significant increases to assets and liabilities on its Consolidated Balance Sheet. The Company is still evaluating the impact of this guidance on its Consolidated Statement of Comprehensive Income. The Company has begun to evaluate the nature of its leases and has compiled preliminary analysis of the type and location of its leases. The Company expects that the significant portion of its leases will relate to property but with additional leases in existence that relate to vehicles and machinery. Revenue Recognition - Adoption of ASC 606 In May 2014, the FASB issued authoritative guidance that provides for a comprehensive model to be used in accounting for revenue arising from contracts with customers (ASC Topic 606 Revenue from Contracts with Customers) (the “Revenue Standard”). Under the Revenue Standard, revenue will be recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. This guidance is applicable to all entities and is effective for annual and interim periods beginning after December 15, 2017. Companies have the option to apply the new guidance under a retrospective approach to each prior reporting period presented or a modified retrospective approach with the cumulative effect of initially applying the new guidance recognized at the date of initial application within the Consolidated Balance Sheet. The Company has determined that it will adopt this guidance using the modified retrospective approach. The Company has substantially completed the evaluation of the Revenue Standard, including updates to it issued by the FASB, and has adopted the Revenue Standard on December 30, 2017, the first day of the Company’s 2018 fiscal year. A cumulative catch up adjustment will be recorded as of that date. The Company creates and manufactures flavors and fragrances. Approximately 90% of products, principally Flavors compounds and Fragrance compounds, are customized to customer specifications and have no alternative use other than sale to the specific customer (“Compounds products”). The remaining revenue is derived largely from Fragrance Ingredient products that, generally, are commodity products with alternative uses and not customized (“Ingredients products”). The Company’s evaluation is substantially complete and was comprised of (i) a detailed review of a large number of documents, including master service, supply, rebate and other similar agreements, and purchase orders, (ii) interviews with regional finance and business personnel on general issues, such as the nature of its larger customer relationships; the nature of potential regional variations; rebates and other price adjustments; upfront costs; and shipping terms and specific issues identified during the review (such as consignment, minimum order quantities, etc.), and (iii) consultation with legal counsel with respect to the nature of various terms within the contracts. Based on this evaluation, with respect to the vast majority of the Company’s contracts for Compounds products, the Company will recognize revenue at a point in time. Specifically, revenue will be recognized upon transfer of control of the product, as the Company does not have an “enforceable right to payment for performance to date” (as set out in section 606-10-25-27 (c) of the Standard). With respect to a small number of Compounds products customers, the Company has determined that it does have an “enforceable right to payment for performance to date” (as set out in section 606-10-25-27 (c) of the Revenue Standard). For contracts where an enforceable right to payment exists the Company will recognize revenue over time using the output method. The calculation of the required cumulative catch up adjustment is in the process of being finalized. It was determined that no adjustment will be required with respect to revenue related to Ingredients products as such products generally have alternative uses and on which the Company does not have an enforceable right to payment at all times during the manufacturing process. In completing its assessment of the adoption of the Revenue Standard the Company elected to combine the shipment of goods with their manufacture to account for both shipment and manufacture as a single performance obligation. Reclassifications and Revisions Certain prior year amounts have been reclassified and revised to conform to the current year presentation. The Consolidated Statement of Cash Flows has been revised to properly reclassify $3.3 million from Net cash used in financing activities to Net cash provided by operating activities for the year ended December 31, 2016. In addition, approximately $5.4 million of expense was recorded during the first quarter of 2017 for a tax assessment relating to prior periods. These adjustments were not material to the current and previously-issued financial statements.

Restructuring and Related Activities [Abstract]
Restructuring and Other Charges	RESTRUCTURING AND OTHER CHARGES Restructuring and other charges primarily consist of separation costs for employees including severance, outplacement and other benefit costs. 2017 Productivity Program On February 15, 2017, the Company announced that it was adopting a multi-year productivity program designed to improve overall financial performance, provide flexibility to invest in growth opportunities and drive long-term value creation. In connection with this program, we expect to optimize our global footprint and simplify the Company's organizational structures globally. In connection with this initiative, the Company expects to incur cumulative, pre-tax cash charges of between $30 - $35 million , consisting primarily of $24 - $26 million in personnel-related costs and an estimated $6 million in facility-related costs, such as lease termination, and integration-related costs. The Company recorded $20.6 million of charges related to personnel-related costs in 2017, with the remainder of the personnel-related and other costs expected to be recognized by the end of 2018. The Company made payments of $14.0 million related to severance in 2017. The overall charges were split approximately evenly between Flavors and Fragrances. This initiative is expected to result in the reduction of approximately 370 members of the Company’s global workforce, including acquired entities, in various parts of the organization. 2015 Severance and Contingent Consideration Charges During 2015, the Company established a series of initiatives intended to streamline its management structure, simplify decision-making and accountability, better leverage and align its capabilities across the organization and improve efficiency of its global manufacturing and operations network. As a result, the Company recorded charges for severance and related costs pertaining to approximately 150 positions that were affected. During 2016, the Company recorded a credit of $1.7 million related to the reversal of severance accruals that were determined to be no longer required. Separately, in 2015, the Company recorded a charge of $7.2 million , included in Selling and administrative expenses, associated with the acceleration from 2016 to 2015 of contingent consideration payments from the Aromor acquisition that were triggered by certain of the management structure changes noted above. In addition, during 2017 , the Company made payments of $0.2 million related to severance and recorded a credit of $2.3 million related to the reversal of severance accruals that were determined to be no longer required. Roll Forward of Liability Movements in severance-related accruals during 2015 , 2016 and 2017 are as follows: (DOLLARS IN THOUSANDS) Employee-Related Costs Other Total Balance at January 1, 2015 $ 759 $ — $ 759 Additional charges (reversals), net 7,594 — 7,594 Payments (471 ) — (471 ) Balance at December 31, 2015 7,882 — 7,882 Additional charges (reversals), net (1,700 ) 658 (1,042 ) Non-cash charges — (658 ) (658 ) Payments (2,905 ) — (2,905 ) Balance at December 31, 2016 3,277 — 3,277 Additional charges (reversals), net 18,309 1,402 19,711 Non-cash charges — (528 ) (528 ) Payments (14,047 ) (456 ) (14,503 ) Balance at December 31, 2017 $ 7,539 $ 418 $ 7,957

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Earnings before income taxes consisted of the following: December 31, (DOLLARS IN THOUSANDS) 2017 2016 2015 U.S. income before taxes $ (24 ) $ 9,078 $ 29,792 Foreign income before taxes 537,069 514,639 509,309 Total income before taxes $ 537,045 $ 523,717 $ 539,101 The income tax provision consisted of the following: December 31, (DOLLARS IN THOUSANDS) 2017 2016 2015 Current tax provision Federal $ 68,886 $ (2,920 ) $ 7,648 State and local 137 1,383 199 Foreign 113,468 105,873 98,964 182,491 104,336 106,811 Deferred tax provision Federal 74,446 8,838 14,379 State and local (11,537 ) (631 ) 399 Foreign (4,020 ) 6,143 (1,735 ) 58,889 14,350 13,043 Total income taxes $ 241,380 $ 118,686 $ 119,854 Effective Tax Rate Reconciliation Reconciliation between the U.S. federal statutory income tax rate to the actual effective tax rate was as follows: December 31, 2017 2016 2015 Statutory tax rate 35.0 % 35.0 % 35.0 % Difference in effective tax rate on foreign earnings and remittances (11.8 ) (11.5 ) (10.7 ) Tax benefit from supply chain optimization (2.3 ) (0.7 ) — Unrecognized tax benefit, net of reversals 2.3 0.6 (0.8 ) U.S. tax reform 26.0 — — Spanish tax charges — — (0.4 ) State and local taxes (2.1 ) 0.1 0.1 Other, net (2.2 ) (0.8 ) (1.0 ) Effective tax rate 44.9 % 22.7 % 22.2 % The effective tax rate reflects the impact of U.S. tax reform as discussed below, partially offset by the benefit from having significant operations outside the U.S. that are taxed at rates that are lower than the U.S. federal rate of 35% and the reversal of a valuation allowance on certain state deferred tax assets. Included in the 2015 effective tax rate was a $10.5 million benefit related to favorable tax rulings in Spain and another jurisdiction for which reserves were previously recorded. The 2017 , 2016 and 2015 effective tax rates were also favorably impacted by the reversals of liabilities for uncertain tax positions of $9.5 million , $7.5 million and $2.8 million , respectively, principally due to statutory expiry and effective settlement. U.S. Tax Reform On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) that significantly revised the U.S. tax code effective January 1, 2018 by, among other things, lowering the corporate income tax rate from a top marginal rate of 35% to a flat 21% and establishing a modified territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. Beginning in 2018, the Act also requires a minimum tax on certain future earnings generated by foreign subsidiaries while providing for future tax-free repatriation of such earnings through a 100% dividends-received deduction. The Tax Act impacted the Company's consolidated results of operations during the 2017 fourth quarter and is expected to continue to impact its consolidated results of operations in future periods. In particular, the transition to the new territorial tax system required the Company to record a one-time tax or “toll charge” which resulted in a provisional incremental tax expense of $100.6 million principally related to previously unremitted earnings on non-U.S. subsidiaries. The cash portion of the "toll charge" will be payable in installments over 8 years beginning in 2018. In addition, the reduction of the U.S. corporate tax rate resulted in a provisional net deferred tax expense of $38.6 million related to the remeasurement of net deferred tax assets as a result of the reduction in the corporate income tax rate. Given the significant complexity of the Tax Act, anticipated guidance from the U.S. Treasury about implementing the Tax Act and the potential for additional guidance from the SEC or the FASB, the Company’s provisional charge may be adjusted during 2018 and is expected to be finalized no later than the fourth quarter of 2018. Other provisions of the Tax Act that impact future tax years are still being assessed. Any material revisions in the Company's computations could adversely affect its cash flows and results of operations. The U.S. consolidated group has historically generated taxable income after the inclusion of foreign dividends which has allowed the Company to realize its federal deferred tax assets. In the future foreign dividends will be subject to a 100% dividends received deduction under the Tax Act and will not serve as a source of taxable income. However, as of December 31, 2017 the U.S. consolidated group is in a cumulative income position and expects to continue to generate future taxable income to realize tax benefits for the reversal of temporary differences. The corresponding U.S. federal taxable income is sufficient to realize $60.3 million in deferred tax assets as of December 31, 2017. The Company’s assessment is provisional as the Company analyzes other provisions of the Tax Act that may impact its U.S. tax profile. Further, as of December 31, 2017 the Company recorded a benefit for $9.2 million related to a valuation allowance release previously recorded against state deferred tax assets. This was due to improved performance of the North American business in 2016 and 2017 and cumulative income from a state perspective. The majority of the Company’s state deferred tax assets relate to net operating loss and tax credit carryforwards that have a specified carryforward period. Therefore, the Company has maintained a valuation allowance of $10.6 million on certain state tax attributes based on a state taxable income forecast. The main input into the forecast is the 2017 taxable income projection. Changes in the performance of the North American business, the Company’s transfer pricing policies and adjustments to the Company’s U.S. tax profile due to the Tax Act could impact the estimate. Deferred Taxes The deferred tax assets consisted of the following amounts: December 31, (DOLLARS IN THOUSANDS) 2017 2016 Employee and retiree benefits $ 87,400 $ 132,638 Credit and net operating loss carryforwards (a) 218,933 186,062 Trademarks and other 11,469 1,406 Amortizable R&D expenses 1,502 4,040 Gain (loss) on foreign currency translation 10,885 (8,799 ) Other, net 11,692 6,016 Gross deferred tax assets 341,881 321,363 Property, plant and equipment, net (11,745 ) (17,000 ) Trademarks and other (73,979 ) (55,899 ) Gross deferred tax liabilities (85,724 ) (72,899 ) Valuation allowance (a) (207,483 ) (152,752 ) Total net deferred tax assets $ 48,674 $ 95,712 _______________________ (a) During 2017 and 2016 , the Company increased its deferred tax assets by $58.8 million and by $7.6 million , respectively, relating to an adjustment to the 2016 and 2015 foreign net operating loss carryforwards, respectively. The entire adjustments of $58.8 million and $7.6 million were offset by corresponding adjustments in valuation allowances. These adjustments are not considered material to the previously issued financial statements. Effective January 1, 2017, the Company prospectively applied new accounting guidance which required all excess tax benefits/deficiencies be recognized as income tax expense/benefit in the Consolidated Statement of Comprehensive Income. This change resulted in a $3.3 million benefit to income tax expense for the year ended December 31, 2017. For 2016, benefits of $5.3 million were recognized in equity. Net operating loss carryforwards were $212.5 million and $149.1 million at December 31, 2017 and 2016 , respectively. If unused, $6.6 million will expire between 2018 and 2037 . The remainder, totaling $205.9 million , may be carried forward indefinitely. Tax credit carryforwards were $12.5 million and $42.8 million at December 31, 2017 and 2016 , respectively. If unused, the $12.2 million will expire between 2018 and 2037. The remaining $0.3 million may be carried forward indefinitely. Of the $225.0 million deferred tax asset for net operating loss carryforwards and credits at December 31, 2017 , the Company considers it unlikely that a portion of the tax benefit will be realized. Accordingly, a valuation allowance of $198.1 million of net operating loss carryforwards and $8.6 million of tax credits has been established against these deferred tax assets, respectively. In addition, due to realizability concerns, the Company established a valuation allowance against certain other net deferred tax assets of $3.2 million . Uncertain Tax Positions A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: December 31, (DOLLARS IN THOUSANDS) 2017 2016 2015 Balance of unrecognized tax benefits at beginning of year $ 26,428 $ 24,198 $ 23,055 Gross amount of increases in unrecognized tax benefits as a result of positions taken during a prior year 1,169 1,254 18 Gross amount of decreases in unrecognized tax benefits as a result of positions taken during a prior year (268 ) (3 ) (43 ) Gross amount of increases in unrecognized tax benefits as a result of positions taken during the current year 13,191 8,131 12,011 The amounts of decreases in unrecognized benefits relating to settlements with taxing authorities — (6,075 ) (10,221 ) Reduction in unrecognized tax benefits due to the lapse of applicable statute of limitation (2,358 ) (1,077 ) (622 ) Balance of unrecognized tax benefits at end of year $ 38,162 $ 26,428 $ 24,198 At December 31, 2017 , 2016 and 2015 , there were $28.5 million , $19.1 million , and $24.2 million , respectively, of unrecognized tax benefits recorded to Other liabilities and $9.7 million and $7.3 million recorded to Other current liabilities for 2017 and 2016, respectively. If these unrecognized tax benefits were recognized, all the benefits and related interest would be recorded as a benefit to income tax expense. For the year ended December 31, 2017 , the Company increased its liabilities for interest and penalties by $3.0 million , net, and increased its liabilities for interest and penalties by $0.3 million , net, and reduced its liabilities by $1.4 million , net for the years ended 2016 and 2015 , respectively. At December 31, 2017 , 2016 and 2015 , the Company had accrued $2.8 million , $0.8 million and $0.8 million , respectively, of interest and penalties classified as Other liabilities and $1.3 million and $0.3 million in 2017 and 2016, respectively, recorded to Other current liabilities. No such liabilities were accrued for the year ended December 31, 2015. As of December 31, 2017 , the Company’s aggregate provision for uncertain tax positions, including interest and penalties, was $42.3 million , associated with various tax positions asserted in foreign jurisdictions, none of which is individually material. Other Tax benefits credited to Shareholders’ equity totaled $0.1 million for the year ended December 31, 2017 , and $0.2 million in each of the years ended December 31, 2016 and 2015 associated with stock option exercises and PRSU dividends. The Tax Act requires a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax and will not be subject to additional U.S. tax when repatriated. Foreign withholding taxes, however, may still apply in certain jurisdictions. The Company has not provided for the foreign withholding taxes with respect to the $1.9 billion of accumulated unremitted earnings of non-U.S. subsidiaries, as management still has the intention and ability to permanently reinvest those earning, but its assessment is provisional under SAB 118. The unrecognized deferred tax liability on these unremitted earnings approximates $72.0 million . The Company has ongoing income tax audits and legal proceedings which are at various stages of administrative or judicial review, of which the material items are discussed below. In addition, the Company has other ongoing tax audits and legal proceedings that relate to indirect taxes, such as value-added taxes, capital tax, sales and use and property taxes, which are discussed in Note 18. The Company also has several other tax audits in process and has open tax years with various taxing jurisdictions that range primarily from 2007 to 2016 . 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 financial position.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Compensation Plans	STOCK COMPENSATION PLANS The Company has various equity plans under which its officers, senior management, other key employees and Board of Directors may be granted options to purchase IFF common stock or other forms of stock-based awards. Beginning in 2004, the Company granted Restricted Stock Units (“RSUs”) as the principal element of its equity compensation for all eligible U.S.-based employees and a majority of eligible overseas employees. Vesting of the RSUs is solely time based; the vesting period is primarily 3 years from date of grant. For a small group of employees, primarily overseas, the Company granted stock options prior to 2008. The cost of all employee stock-based awards are principally recognized on a straight-line attribution basis over their respective vesting periods, net of estimated forfeitures. Total stock-based compensation expense included in the Consolidated Statement of Income and Comprehensive Income was as follows: December 31, (DOLLARS IN THOUSANDS) 2017 2016 2015 Equity-based awards $ 26,567 $ 24,587 $ 23,160 Liability-based awards 6,014 3,884 4,784 Total stock-based compensation 32,581 28,471 27,944 Less tax benefit (5,659 ) (7,375 ) (8,348 ) Total stock-based compensation, net of tax $ 26,922 $ 21,096 $ 19,596 The shareholders of the Company approved the Company’s 2015 Stock Award and Incentive Plan (the “2015 Plan”) on May 6, 2015. The 2015 Plan replaced the Company’s 2010 Stock Award and Incentive Plan (the “2010 Plan”) and provides the source for future deferrals of cash into deferred stock under the Company’s Deferred Compensation Plan (with the Deferred Compensation Plan being deemed a subplan under the 2015 Plan for the sole purpose of funding deferrals under the IFF Share Fund). Under the 2015 Plan, a total of 1,500,000 shares are authorized for issuance in addition to 1,552,694 shares remaining available under the 2010 plan that were rolled into the 2015 Plan. At December 31, 2017 , 865,349 shares were subject to outstanding awards and 2,351,560 shares remained available for future awards under all of the Company’s equity award plans, including the 2015 Plan (excluding shares not yet issued under open cycles of the Company’s Long-Term Incentive Plan). The Company offers a Long-Term Incentive Plan (“LTIP”) for senior management. The targeted payout is 50% cash and 50% IFF common stock at the end of the three -year cycle and provides for segmentation in which one-fourth of the award vests during each twelve-month period, with the final one-fourth segment vesting over the full three-year period. Grants under the LTIP are currently earned upon achievement of defined Economic Profit ("EP") targets and the Company's performance ranking of Total Shareholder Return as a percentile of the S&P 500 ("Relative TSR"). EP measures operating profitability after considering (i) all operating costs, (ii) income taxes and (iii) a charge for the capital employed in the business. When the award is granted, 50% of the target dollar value of the award is converted to a number of “notional” shares based on the closing price at the beginning of the cycle. For those shares whose payout is based on Relative TSR, compensation expense is recognized using a graded-vesting attribution method, while compensation expense for the remainder of the performance shares (EP targets) is recognized on a straight-line basis over the vesting period based on the probable outcome of the performance condition. The 2013 - 2015 cycle concluded at the end of 2015 and an aggregate 73,134 shares of common stock were issued in March 2015. The 2014 - 2016 cycle concluded at the end of 2016 and an aggregate 47,267 shares of common stock were issued in March 2016. The 2015 - 2017 cycle concluded at the end of 2017 and an aggregate 46,091 shares of common stock will be issued in March 2018. In 2006, the Board of Directors approved the Equity Choice Program (the “Program”) for senior management. This program continues under the 2015 Plan. Eligible employees can choose from among three equity alternatives and will be granted such equity awards up to certain dollar awards depending on the participant’s employment grade level. A participant may choose among (1) SSARs, (2) RSUs or (3) PRSUs. SSARs and Options SSARs are a contractual right to receive the value, in shares of Company stock, of the appreciation in our stock price from the grant date to the date the SSARs are exercised by the participant. SSARs granted become exercisable on the third anniversary of the grant date and have a maximum term of 7 years . SSARs do not require a financial investment by the SSARs grantee. An immaterial amount of SSARS was granted in 2015. No SSARs were granted in 2017 or 2016 . Stock options require the participant to pay the exercise price at the time they exercise their stock options. No stock options were granted in 2017 , 2016 or 2015 . SSARs and options activity was as follows: (SHARE AMOUNTS IN THOUSANDS) Shares Subject to SSARs/Options Weighted Average Exercise Price SSARs/ Options Exercisable December 31, 2016 19 $ 59.14 18 Exercised (15 ) 57.66 Canceled — — Balance at December 31, 2017 4 $ 64.25 4 The weighted average exercise price of SSARs and options exercisable at December 31, 2017 , 2016 and 2015 were $60.39 , $58.24 and $52.10 , respectively. SSARs and options outstanding at December 31, 2017 was as follows: Price Range Number Outstanding (in thousands) Weighted Average Remaining Contractual Life (in years) Weighted Average Exercise Price Aggregate Intrinsic Value (in thousands) $51 – $60 4 1.34 $ 60.39 Over $65 — 4.35 118.10 Total 4 $ 64.25 $ 376 SSARs and options exercisable as of December 31, 2017 was as follows: Price Range Number Exercisable (in thousands) Weighted Average Remaining Contractual Life (in years) Weighted Average Exercise Price Aggregate Intrinsic Value (in thousands) $51 – $60 4 1.34 $ 60.39 4 $ 60.39 $ 366 The total intrinsic value of options/SSARs exercised during 2017 , 2016 and 2015 totaled $1.2 million , $1.3 million and $7.3 million , respectively. As of December 31, 2017 , there was less than $0.1 million of total unrecognized compensation cost related to non-vested SSARs granted; such cost is expected to be recognized over a period of 0.27 years. Restricted Stock Units The Company has granted RSUs to eligible employees and members of the Board of Directors. Such RSUs are subject to forfeiture if certain conditions are not met. RSUs principally vest 100% at the end of 3 years and contain no performance criteria provisions. An RSU’s fair value is calculated based on the market price of the Company's stock at date of grant, with an adjustment to reflect the fact that such awards do not participate in dividend rights. The aggregate fair value is amortized to expense ratably over the vesting period. RSU activity was as follows: Number of Shares (in thousands) Weighted Average Grant Date Fair Value Per Share December 31, 2016 444 $ 107.43 Granted 161 131.36 Vested (140 ) 95.52 Forfeited (24 ) 115.79 Balance at December 31, 2017 441 $ 119.45 The total fair value of RSUs that vested during the year ended December 31, 2017 was $18.4 million . As of December 31, 2017 , there was $23.2 million of total unrecognized compensation cost related to non-vested RSUs granted under the equity incentive plans; such cost is expected to be recognized over a weighted average period of 1.9 years. Purchased Restricted Stock and Purchased Restricted Stock Units In 2014, the grant of awards under the Equity Choice program provided for eligible employees to purchase restricted shares of IFF common stock and deposit them into an escrow account. For each share deposited in escrow by the eligible employee, the Company matched with a grant of a share of restricted stock or, for non-U.S. participants, a restricted stock unit. The shares of restricted stock and restricted stock units generally vest on the third anniversary of the grant date, are subject to continued employment and other specified conditions, and pay dividends if and when paid by the Company. Holders of restricted stock have, in most instances, all of the rights of stockholders, except that they may not sell, assign, pledge or otherwise encumber such shares. The PRSUs provide no such rights. During 2015, the Company modified the program so that all participants, including U.S. participants, began to receive a restricted stock unit instead of a share of restricted stock. Restricted stock units pay dividend equivalents and do not have voting rights. The following table summarizes the Company's activity for the years ended December 31, 2017, 2016 and 2015: (DOLLARS IN MILLIONS) Issued Shares Aggregate Purchase Price Covered Shares PRSU PRS PRSU PRS 2017 41,801 — $ 5.8 $ — 20,901 2016 58,629 — 7.0 — 29,315 2015 14,622 52,577 1.7 6.2 33,600 PRS and PRSU activity was as follows: (SHARE AMOUNTS IN THOUSANDS) Number of Shares Weighted Average Grant Date Fair Value Per Share December 31, 2016 198 $ 110.62 Granted 42 138.83 Vested (79 ) 98.26 Forfeited (2 ) 118.95 Balance at December 31, 2017 159 $ 124.15 The total fair value of PRS and PRSUs that vested during the year ended December 31, 2017 was $10.4 million . As of December 31, 2017 , there was $7.8 million of total unrecognized compensation cost related to non-vested PRS and PRSUs granted under the equity incentive plans; such cost is expected to be recognized over a weighted average period of 1.7 years. Liability Awards The Company has granted cash-settled RSUs ("Cash RSUs") to eligible employees that are paid out 100% in cash upon vesting. Such RSUs are subject to forfeiture if certain conditions are not met. Cash RSUs principally vest 100% at the end of three years and contain no performance criteria provisions. A Cash RSU's fair value is calculated based on the market price of the Company's stock at the date of the closing period and is accounted for as a liability award. The aggregate fair value is amortized to expense ratably over the vesting period. Cash RSU activity was as follows: (SHARE AMOUNTS IN THOUSANDS) Cash RSUs Weighted Average Fair Value Per Share December 31, 2016 96 $ 117.83 Granted 32 152.61 Vested (31 ) 138.62 Forfeited (2 ) 132.80 Balance at December 31, 2017 95 $ 152.61 The total fair value of Cash RSUs that vested during the year ended December 31, 2017 was $4.1 million . As of December 31, 2017 , there was $6.4 million of total unrecognized compensation cost related to non-vested Cash RSUs granted under the equity incentive plans; such cost is expected to be recognized over a weighted average period of 1.8 years. The aggregate compensation cost will be adjusted based on changes in the Company’s stock price.

Retirement Benefits [Abstract]
Employee Benefits	EMPLOYEE BENEFITS The Company has pension and/or other retirement benefit plans covering approximately one-fourth of active employees. In 2007, the Company amended its U.S. qualified and non-qualified pension plans under which accrual of future benefits was suspended for all participants that did not meet the rule of 70 (age plus years of service equal to at least 70 as of December 31, 2007). Pension benefits are generally based on years of service and compensation during the final years of employment. Plan assets consist primarily of equity securities and corporate and government fixed income securities. Substantially all pension benefit costs are funded as accrued; such funding is limited, where applicable, to amounts deductible for income tax purposes. Certain other retirement benefits are provided by general corporate assets. The Company sponsors a qualified defined contribution plan covering substantially all U.S. employees. Under this plan, the Company matches 100% of participants’ contributions up to 4% of compensation and 75% of participants’ contributions from over 4% to 8% . Employees that are still eligible to accrue benefits under the pension plans are limited to a 50% match of up to 6% of the participants’ compensation. In addition to pension benefits, certain health care and life insurance benefits are provided to qualifying U.S. employees upon retirement from IFF. Such coverage is provided through insurance plans with premiums based on benefits paid. The Company does not generally provide health care or life insurance coverage for retired employees of foreign subsidiaries; such benefits are provided in most foreign countries by government-sponsored plans, and the cost of these programs is not material. The Company offers a non-qualified Deferred Compensation Plan ("DCP") for certain key employees and non-employee directors. Eligible employees and non-employee directors may elect to defer receipt of salary, incentive payments and Board of Directors’ fees into participant-directed investments which are generally invested by the Company in individual variable life insurance contracts it owns that are designed to informally fund savings plans of this nature. The cash surrender value of life insurance is based on the net asset values of the underlying funds available to plan participants. At December 31, 2017 and December 31, 2016 , the Consolidated Balance Sheet reflects liabilities of $43.0 million and $37.6 million , respectively, related to the DCP in Other liabilities and $22.5 million and $18.8 million , respectively, included in Capital in excess of par value related to the portion of the DCP that will be paid out in IFF shares. The total cash surrender value of life insurance contracts the Company owns in relation to the DCP and post-retirement life insurance benefits amounted to $45.2 million and $43.4 million at December 31, 2017 and 2016 , respectively, and are recorded in Other assets in the Consolidated Balance Sheet. As of January 1, 2017, the Company changed its approach for calculating the discount rate which is applied to the Consolidated Balance Sheet and Consolidated Statement of Comprehensive Income from a single weighted-average discount rate approach to a multiple discount rate approach. The impact of this change for the full year 2017 was a reduction of approximately $8 million in pension expense. During 2017, a pension settlement charge of $2.8 million was recorded related to one of the Company's U.K. plans. The settlement charge was triggered by the payment of large lump sum payments made to participants leaving the plan. The plan assets and benefit obligations of the defined benefit pension plans are measured at December 31 of each year.

Contributions in Following Year (2018) $ 4,121 $ 17,104 $ 5,022 The Company considers a number of factors in determining and selecting assumptions for the overall expected long-term rate of return on plan assets. The Company considers the historical long-term return experience of its assets, the current and expected allocation of its plan assets and expected long-term rates of return. The Company derives these expected long-term rates of return with the assistance of its investment advisors. The Company bases its expected allocation of plan assets on a diversified portfolio consisting of domestic and international equity securities, fixed income, real estate and alternative asset classes. The asset allocation is monitored on an ongoing basis. The Company considers a variety of factors in determining and selecting its assumptions for the discount rate at December 31. For the U.S. plans, the discount rate was based on the internal rate of return for a portfolio of high quality bonds rated Aa or higher by either Moody’s or Standard & Poor's with maturities that are consistent with the projected future benefit payment obligations of the plan. For the Non-U.S. Plans, the discount rates were determined by region and are based on high quality long-term corporate bonds. Consideration has been given to the duration of the liabilities in each plan when selecting the bonds to be used in determining the discount rate. The rate of compensation increase for all plans and the medical cost trend rate for the applicable U.S. plans are based on plan experience. The percentage of assets in the Company's pension plans, by type, is as follows: U.S. Plans Non-U.S. Plans 2017 2016 2017 2016 Cash and cash equivalents 1 % — % 4 % 2 % Equities 28 % 36 % 27 % 27 % Fixed income 71 % 64 % 40 % 56 % Property — % — % 4 % 5 % Alternative and other investments — % — % 25 % 10 % With respect to the U.S. plans, the expected return on plan assets was determined based on an asset allocation model using the current target allocation, real rates of return by asset class and an anticipated inflation rate. The target investment allocation is 20% equity securities and 80% fixed income securities. The expected annual rate of return for the non-U.S. plans employs a similar set of criteria adapted for local investments, inflation rates and in certain cases specific government requirements. The target asset allocation, for the non-U.S. plans, consists of approximately: 40% – 70% in fixed income securities; 15% – 40% in equity securities; 5% – 20% in real estate; and 5% – 10% in alternative investments. The following tables present the Company's plan assets for the U.S. and non-U.S. plans using the fair value hierarchy as of December 31, 2017 and 2016 . The plans’ assets were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and their placement within the fair value hierarchy levels. For more information on a description of the fair value hierarchy, see Note 15.

Other cash and cash equivalents are valued daily by the fund using a market approach with inputs that include quoted market prices for similar instruments. Equity securities are primarily valued using a market approach based on the quoted market prices of identical instruments. Pooled funds are typically common or collective trusts valued at their net asset values (NAVs). Fixed income securities are primarily valued using a market approach with inputs that include broker quotes and benchmark yields. Derivative instruments are valued by the custodian using closing market swap curves and market derived inputs. Real estate values are primarily based on valuation of the underlying investments, which include inputs such as cost, discounted future cash flows, independent appraisals and market comparable data. Hedge funds are valued based on valuation of the underlying securities and instruments within the funds. Quoted market prices are used when available and NAVs are used for unquoted securities within the funds. Absolute return funds are actively managed funds mainly invested in debt and equity securities and are valued at their NAVs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Fair Value Accounting guidance on fair value measurements specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 — Quoted prices for identical instruments in active markets. • Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 — Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable . This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. The Company determines the fair value of structured liabilities (where performance is linked to structured interest rates, inflation or currency risks) using the London Interbank Offer Rate (“LIBOR”) swap curve and forward interest and exchange rates at period end. Such instruments are classified as Level 2 based on the observability of significant inputs to the model. The Company does not have any instruments classified as Level 1 or Level 3, other than those included in pension asset trusts included in Note 14. These valuations take into consideration the Company's credit risk and its counterparties’ credit risk. The estimated change in the fair value of these instruments due to such changes in its own credit risk (or instrument-specific credit risk) was immaterial as of December 31, 2017 . The principal amounts and the estimated fair values of financial instruments at December 31 consisted of the following: 2017 2016 (DOLLARS IN THOUSANDS) Principal Fair Value Principal Fair Cash and cash equivalents (1) $ 368,046 $ 368,046 $ 323,992 $ 323,992 Credit facilities and bank overdrafts (2) 7,993 7,993 13,599 13,599 Long-term debt: (3) Senior notes - 2007 250,000 293,232 500,000 556,222 Senior notes - 2013 300,000 304,219 300,000 302,376 Euro Senior notes - 2016 594,400 627,782 520,650 546,006 Senior notes - 2017 500,000 525,906 — — _______________________ (1) The carrying amount of cash and cash equivalents approximates fair value due to the short maturity of those instruments. (2) The carrying amount of the Company's credit facilities and bank overdrafts approximates fair value as the interest rate is reset frequently based on current market rates as well as the short maturity of those instruments. (3) The fair value of the Company's long-term debt was calculated using discounted cash flows applying current interest rates and current credit spreads based on its own credit risk. Derivatives The Company periodically enters into foreign currency forward contracts with the objective of reducing exposure to cash flow volatility associated with its intercompany loans, foreign currency receivables and payables and anticipated purchases of certain raw materials used in operations. These contracts generally involve the exchange of one currency for a second currency at a future date, have maturities not exceeding twelve months and are with counterparties which are major international financial institutions. During the years ended December 31, 2017 and 2016 , the Company entered into several forward currency contracts which qualified as net investment hedges, in order to mitigate a portion of its net European investments from foreign currency risk. The effective portions of net investment hedges are recorded in other comprehensive income ("OCI") as a component of Foreign currency translation adjustments in the accompanying Consolidated Statement of Income and Comprehensive Income. Realized gains/(losses) are deferred in AOCI where they will remain until the net investments in the Company's European subsidiaries are divested. Seventeen of these forward currency contracts matured during the year ended December 31, 2017 . The outstanding forward currency contacts have remaining maturities of less than one year . Subsequent to the issuance of the Euro Senior Notes - 2016 during the first quarter of 2016, the Company designated the debt as a hedge of a portion of its net European investments. Accordingly, the change in the value of the debt that is attributable to foreign exchange movements is recorded in OCI as a component of Foreign currency translation adjustments in the accompanying Consolidated Statement of Income and Comprehensive Income. During the year ended December 31, 2017 and 2016 , the Company entered into several forward currency contracts which qualified as cash flow hedges. The objective of these hedges is to protect against the currency risk associated with forecasted U.S. dollar ("USD") denominated raw material purchases made by Euro ("EUR") functional currency entities which result from changes in the EUR/USD exchange rate. The effective portions of cash flow hedges are recorded in OCI as a component of Gains/(Losses) on derivatives qualifying as hedges in the accompanying Consolidated Statement of Income and Comprehensive Income. Realized gains/(losses) in AOCI related to cash flow hedges of raw material purchases are recognized as a component of Cost of goods sold in the accompanying Consolidated Statement of Income and Comprehensive Income in the same period as the related costs are recognized. During 2015, the Company entered into interest rate swap agreements that effectively converted the fixed rate on a portion of its long-term borrowings to a variable short-term rate based on the LIBOR plus an interest markup. These swaps are designated as fair value hedges. Amounts recognized in Interest expense were immaterial for the years ended December 31, 2017 , 2016 and 2015 . During the first quarter of 2016, the Company entered into and terminated two Euro interest rate swap agreements to hedge the anticipated issuance of fixed-rate debt. These swaps were designated as cash flow hedges. The effective portions of cash flow hedges are recorded in OCI as a component of Losses on derivatives qualifying as hedges in the accompanying Consolidated Statement of Comprehensive Income. The Company incurred a loss of € 2.9 million ( $3.2 million ) due to the termination of these swaps. The loss is being amortized as interest expense over the life of the Euro Senior Notes - 2016 as discussed in Note 9. During the fourth quarter of 2016 and the first quarter of 2017, the Company entered into interest rate swap agreements to hedge the anticipated issuance of fixed-rate debt, which are designated as cash flow hedges. The various hedge instruments were settled upon issuance of the debt on May 18, 2017 and resulted in a loss of approximately $5.3 million . As discussed in Note 9, the loss is being amortized as interest expense over the life of the Senior Notes - 2017. During the first quarter of 2013, the Company entered into three interest rate swap to hedge the anticipated issuance of fixed-rate debt, which are designated as cash flow hedges. The effective portions of cash flow hedges are recorded in OCI as a component of Losses/gains on derivatives qualifying as hedges in the accompanying Consolidated Statement of Income and Comprehensive Income. During the second quarter of 2013, the Company terminated these swaps and incurred a loss of $2.7 million , which it will amortize as Interest expense over the life of the Senior Notes - 2013 (discussed in Note 9).

The ineffective portion of the above noted cash flow hedges and net investment hedges was not material for the years ended December 31, 2017 and 2016 . The Company expects approximately $3.9 million (net of tax), of derivative gains included in AOCI at December 31, 2017 , based on current market rates, will be reclassified into earnings within the next twelve months. The majority of this amount will vary due to fluctuations in foreign currency exchange rates.

The Consolidated Balance Sheet reflects $54.4 million of dividends payable at December 31, 2017 . This amount relates to a cash dividend of $0.69 per share declared in December 2017 and paid in January 2018 . Dividends declared, but not paid as of December 31, 2016 and December 31, 2015 were $50.7 million ( $0.64 per share) and $44.8 million ( $0.56 per share), respectively. Share Repurchases In December 2012, the Board of Directors authorized a $250.0 million share repurchase program, which commenced in the first quarter of 2013. In August 2015, the Board of Directors approved an additional $250 million share repurchase authorization and extension through December 31, 2017. Based on the total remaining amount of $56.1 million available under the amended repurchase program as of October 31, 2017, the Board of Directors re-approved on November 1, 2017 a $250.0 million share repurchase authorization and extension for a total value of $300.0 million available under the program. A summary of the stock repurchase activity under the stock repurchase program, reported based on the trade date, is summarized as follows: (DOLLARS IN THOUSANDS) Shares Repurchased Weighted- Average Price per Share Dollar Amount Repurchased Year Ended December 31, 2017 459,264 $ 126.44 $ 58,069 Year Ended December 31, 2016 1,058,018 124.01 127,443 Year Ended December 31, 2015 1,074,210 114.90 121,193 Based on the total remaining amount of $295.1 million available under the repurchase program, 1,933,959 shares, or 2.4% of shares outstanding (based on the market price and weighted average shares outstanding as of December 31, 2017 ) could be repurchased under the program as of December 31, 2017 . The purchases will be made from time to time on the open market or through private transactions as market and business conditions warrant. Repurchased shares will be placed into treasury stock. The ultimate level of purchases will be a function of the daily purchase limits established in the pre-approved program according to the share price at that time. This plan expires on November 1, 2022.

Risks and Uncertainties [Abstract]
Concentrations of Credit Risk	CONCENTRATIONS OF CREDIT RISK The Company does not have significant concentrations of risk in financial instruments. Temporary investments are made in a well-diversified portfolio of high-quality, liquid obligations of government, corporate and financial institutions. There are also limited concentrations of credit risk with respect to trade receivables because the Company has a large number of customers who are spread across many industries and geographic regions. The Company’s larger customers are each spread across many sub-categories of its segments and geographical regions. The Company had one customer that accounted for more than 10% of its consolidated net sales in each year for all periods presented.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Lease Commitments Minimum rental payments under non-cancelable operating leases are $36.2 million in 2018 , $33.9 million in 2019 , $30.8 million in 2020 , $29.3 million in 2021 and $153.4 million in 2022 and thereafter through 2063. The corresponding rental expense was $37.8 million , $35.4 million and $33.6 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. None of our leases contain escalation clauses and they do not require capital improvement funding. Guarantees and Letters of Credit The Company has various bank guarantees and letters of credit which are available for use to support its ongoing business operations and to satisfy governmental requirements associated with pending litigation in various jurisdictions. At December 31, 2017 , the Company had total bank guarantees and standby letters of credit of approximately $51.7 million with various financial institutions. Included in the above aggregate amount is a total of $15.7 million for other assessments in Brazil for various income tax and indirect tax disputes related to fiscal years 1998-2011. There were no material amounts utilized under the standby letters of credit as of December 31, 2017 . In order to challenge the assessments in these cases in Brazil, the Company has been required to and has separately pledged assets, principally property, plant and equipment to cover assessments in the amount of approximately $15.0 million as of December 31, 2017 . Lines of Credit The Company has various lines of credit which are available to support its ongoing business operations. As of December 31, 2017 , the Company had available lines of credit (in addition to the $950.0 million of capacity under the Credit Facility as discussed in Note 9) of approximately $105.4 million with various financial institutions. There were no material amounts drawn down pursuant to these lines of credit as of December 31, 2017 . Litigation The Company assesses contingencies related to litigation and/or other matters to determine the degree of probability and range of possible loss. A loss contingency is accrued in the Company’s consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly sensitive and requires judgments about future events. On at least a quarterly basis, the Company reviews contingencies related to litigation to determine the adequacy of accruals. The amount of ultimate loss may differ from these estimates and further events may require the Company to increase or decrease the amounts it has accrued on any matter. Periodically, the Company assesses its insurance coverage for all known claims, where applicable, taking into account aggregate coverage by occurrence, limits of coverage, self-insured retentions and deductibles, historical claims experience and claims experience with its insurance carriers. The liabilities are recorded at management’s best estimate of the probable outcome of the lawsuits and claims, taking into consideration the facts and circumstances of the individual matters as well as past experience on similar matters. At each balance sheet date, the key issues that management assesses are whether it is probable that a loss as to asserted or unasserted claims has been incurred and if so, whether the amount of loss can be reasonably estimated. The Company records the expected liability with respect to claims in Other liabilities and expected recoveries from its insurance carriers in Other assets. The Company recognizes a receivable when it believes that realization of the insurance receivable is probable under the terms of the insurance policies and its payment experience to date. Environmental Over the past 20 years, various federal and state authorities and private parties have claimed that we are a Potentially Responsible Party (“PRP”) as a generator of waste materials for alleged pollution at a number of waste sites operated by third parties located principally in New Jersey and have sought to recover costs incurred and to be incurred to clean up the sites. The Company has been identified as a PRP at eight facilities operated by third parties at which investigation and/or remediation activities may be ongoing. The Company analyzes its potential liability on at least a quarterly basis and accrues for environmental liabilities when they are probable and estimable. The Company estimates its share of the total future cost for these sites to be less than $5 million . While joint and several liability is authorized under federal and state environmental laws, the Company believes the amounts it has paid and anticipates paying in the future for clean-up costs and damages at all sites are not and will not have a material adverse effect on its financial condition, results of operations or liquidity. This assessment is based upon, among other things, the involvement of other PRPs at most of the sites, the status of the proceedings, including various settlement agreements and consent decrees and the extended time period over which payments will likely be made. There can be no assurance, however, that future events will not require the Company to materially increase the amounts it anticipates paying for clean-up costs and damages at these sites, and that such increased amounts will not have a material adverse effect on its financial condition, results of operations or cash flows. China Facilities Guangzhou Flavors plant During 2015, the Company was notified by Chinese authorities of compliance issues pertaining to the emission of odors from several of its plants in China. As a result, the Company's Guangzhou Flavors plant in China was temporarily idled in 2015. The Company has made additional capital improvements in odor-abatement equipment at these plants to address these issues and is in the process of building a second Flavors plant in China, which is expected to begin operating in the first quarter of 2019. During the fourth quarter of 2016, the Company was notified that certain governmental authorities have begun to evaluate a change in the zoning of the Guangzhou Flavors plant. The zoning, if changed, would prevent the Company from continuing to manufacture product at the existing plant. The ultimate outcome of any change that the governmental authorities may propose, the timing of such a change and the nature of any compensation arrangements that might be provided to the Company are uncertain. The net book value of the existing plant was approximately $68 million as of December 31, 2017 . Zhejiang Ingredients plant In the first quarter of 2016, the Company received a request from the Chinese government to relocate its Fragrance Ingredients plant in Zhejiang, China (the plant is located in Hangzhou City in the Zhejiang province). Since then, the Company has been in discussions with the government regarding the timing of the requested relocation and the amount and nature of government compensation to be provided to the Company. In the fourth quarter of 2017, the Company concluded discussions with the government and, based on the agreements reached, expects to receive total compensation payments up to approximately $50 million . The relocation compensation will be paid to the Company over the period of the relocation which is expected to be through the end of 2020. The Company received the first payment of $15 million in the fourth quarter of 2017. Remaining payments will be paid to the Company based on specified milestones. The net book value of the current plant was approximately $25 million as of December 31, 2017 . The Company expects to relocate approximately half of production capacity of the facility by the middle of 2019 and the remainder of the production capacity of the facility by the middle of 2020. Total China Operations The total net book value of all five plants in China ( one of which is currently under construction) was approximately $151.4 million as of December 31, 2017 . If the Company is required to close a plant, or operate one at significantly reduced production levels on a permanent basis, the Company may be required to record charges that could have a material impact on its consolidated financial results of operations, financial position and cash flows in future periods. Other Contingencies The Company has contingencies involving third parties (such as labor, contract, technology or product-related claims or litigation) as well as government-related items in various jurisdictions in which it operates pertaining to such items as value-added taxes, other indirect taxes, customs and duties and sales and use taxes. It is possible that cash flows or results of operations, in any period, could be materially affected by the unfavorable resolution of one or more of these contingencies. The most significant government-related contingencies exist in Brazil. With regard to the Brazilian matters, the Company believes it has valid defenses for the underlying positions under dispute; however, in order to pursue these defenses, the Company is required to, and has provided, bank guarantees and pledged assets in the aggregate amount of $30.7 million . The Brazilian matters take an extended period of time to proceed through the judicial process and there are a limited number of rulings to date. ZoomEssence As previously disclosed, in March 2012, ZoomEssence, Inc. filed a complaint against the Company in the U.S. District Court for the District of New Jersey alleging trade secret misappropriation, breach of contract and unjust enrichment in connection with certain spray dry technology disclosed to the Company. ZoomEssence sought an injunction and monetary damages. In November 2014, the Company filed a counterclaim against ZoomEssence alleging trade secret misappropriation, breach of contract, breach of the implied covenant of good faith and fair dealing, unjust enrichment, misappropriation of confidential and proprietary information, common law unfair competition, tortious interference with contractual relations, and conversion. During the second quarter of 2017, the Company and ZoomEssence mutually agreed to settle all claims and counterclaims. The parties agreed to dismiss their claims against one another, with prejudice and without any admission of liability or wrongful conduct, to avoid any further expense and disruption from the litigation. The complaint was dismissed, with prejudice, on July 5, 2017. Under the settlement agreement, the Company made a one-time payment to ZoomEssence of $56 million during the second quarter of 2017 and the parties exchanged full mutual releases. Accordingly, the Company recorded an additional charge of $1.0 million during the second quarter of 2017. FDA-Mandated Product Recall The Company periodically incurs product liability claims based on product that is sold to customers that may be defective or otherwise not in accordance with the customer’s requirements. In the first quarter of 2017, the Company was made aware of a claim for product that was subject to a product recall. As of December 31, 2017 , the Company had recorded a total charge of approximately $12.8 million with respect to this claim. In addition to the charge of $1.8 million recorded in the first quarter of 2017, an additional $3.5 million was recorded during the second quarter of 2017 and $7.5 million recorded during the fourth quarter of 2017. Additionally, $3.1 million was paid in the fourth quarter of 2017 to the customer relating to the product claim. The second quarter charge reflects additional information on specific volumes of affected products. The fourth quarter charge reflects additional information received regarding business interruption loss, including the amount of product that was ultimately returned and the customer’s direct manufacturing and other production costs, costs related to the customer’s recall efforts, costs to dispose of the defective product, legal and administrative costs, and other claims that the customer made. The amounts accrued represents an accrual for the claim based on management's best estimate of losses. While it is probable that the Company will incur additional losses related to this claim, the amount of the ultimate claim that will be paid is not currently estimable until the Company has completed the evaluation of support provided and has completed appropriate discussions with claimants. While it is not currently possible to estimate the amount of losses, such losses when recorded will affect income from operations in future individual quarters. The Company does not believe that the ultimate settlement of the claim will have a material impact on its financial condition. Separately, the Company expects to pursue reimbursement of all or a portion of costs, once incurred, from its insurance company and/or the supplier; however, the nature, timing and amount of any such reimbursement cannot be determined at this time. Other The Company determines estimates of reasonably possible losses or ranges of reasonably possible losses in excess of related accrued liabilities, if any, when it has determined that either a loss is reasonably possible or a loss in excess of accrued amounts is reasonably possible and the amount of losses or range of losses is determinable. For all third party contingencies (including labor, contract, technology, tax, product-related claims and business litigation), the Company currently estimates that the aggregate range of reasonably possible losses in excess of any accrued liabilities is $0 to approximately $15 million . The estimates included in this amount are based on the Company’s analysis of currently available information and, as new information is obtained, these estimates may change. Due to the inherent subjectivity of the assessments and the unpredictability of outcomes of legal proceedings, any amounts accrued or included in this aggregate amount may not represent the ultimate loss to the Company from the matters in question. Thus, the Company’s exposure and ultimate losses may be higher or lower, and possibly significantly so, than the amounts accrued or the range disclosed above. Spanish Capital Tax The Spanish tax authorities alleged claims for a capital tax and the Appellate Court rejected one of the two bases upon which the Company based its capital tax position. On January 22, 2014, the Company filed an appeal and in order to avoid future interest costs in the event its appeal was unsuccessful, the Company paid € 9.8 million ( $11.2 million , representing the principal amount) during the first quarter of 2014. On February 24, 2016, the Company received a favorable ruling on its appeal from the Spanish Supreme Court which overruled a lower court ruling. As a result of this decision, the Company reversed the previously recorded provision of € 9.8 million ( $10.5 million ) for the year ended December 31, 2015. During 2016, the Company recorded additional income of $2.3 million related to the finalization of amounts received from the authorities. This amount has principally been reflected as a reduction of administrative expense.

Nature of Operations and Summ28

Nature of Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Fiscal Year End	The Company has historically operated on a 52/53 week fiscal year generally ending on the Friday closest to the last day of the year. For ease of presentation, December 31 is used consistently throughout the financial statements and notes to represent the period-end date. The 2017, 2016 and 2015 fiscal years were 52 week periods. For the 2017 , 2016 and 2015 fiscal years, the actual closing dates were December 29, December 30 and January 1, respectively.
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Actual results may ultimately differ from estimates.
Principles of Consolidation	The consolidated financial statements include the accounts of International Flavors & Fragrances Inc. and those of its subsidiaries. Significant intercompany balances and transactions have been eliminated. To the extent a subsidiary is not wholly owned, any related noncontrolling interest is included as a separate component of Shareholders’ Equity. Any applicable expense (income) attributable to the noncontrolling interest is included in Other expense, net in the accompanying Consolidated Statement of Income and Comprehensive Income due to its immateriality and, as such, is not presented separately.
Revenue Recognition	The Company recognizes revenue when the earnings process is complete. This generally occurs when (i) title and risk of loss have been transferred to the customer in accordance with the terms of sale and (ii) collection is reasonably assured. Sales are reduced, at the time revenue is recognized, for applicable discounts, rebates and sales allowances based on historical experience. Related accruals are included in Other current liabilities in the accompanying Consolidated Balance Sheet.
Foreign Currency Translation	The Company translates the assets and liabilities of non-U.S. subsidiaries into U.S. dollars at year-end exchange rates. Income and expense items are translated at average exchange rates during the year. Cumulative translation adjustments are shown as a separate component of Shareholders’ Equity.
Research and Development	Research and development (“R&D”) expenses relate to the development of new and improved flavors or fragrances, technical product support and compliance with governmental regulation. All research and development costs are expensed as incurred.
Cash Equivalents	Cash equivalents include highly liquid investments with maturities of three months or less at date of purchase.
Accounts Receivable	The Company sells certain accounts receivable on a non-recourse basis to unrelated financial institutions under “factoring” agreements that are sponsored, solely and individually, by certain customers. The Company accounts for these transactions as sale of receivables, removes the receivables sold from its financial statements, and records cash proceeds when received by the Company.
Inventories	Inventories are stated at the lower of cost (on a weighted-average basis) or market.
Property, Plant and Equipment	Property, plant and equipment are recorded at cost. Depreciation is calculated on a straight-line basis, principally over the following estimated useful lives: buildings and improvements, 10 to 40 years; machinery and equipment, 3 to 20 years; information technology hardware and software, 3 to 7 years; and leasehold improvements which are included in buildings and improvements, the estimated life of the improvements or the remaining term of the lease, whichever is shorter.
Finite-Lived Intangible Assets	Finite-lived intangible assets include customer relationships, patents, trade names, technological know-how and other intellectual property valued at acquisition and amortized on a straight-line basis over the following estimated useful lives: customer relationships, 11 - 23 years; patents, 5 - 15 years; trade names, approximately 30 years; and technological know-how, 5 - 28 years. The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their full carrying value may not be recovered. An estimate of undiscounted future cash flows produced by an asset or group of assets is compared to the carrying value to determine whether impairment exists. If assets are determined to be impaired, the loss is measured based on an estimate of fair value using various valuation techniques, including a discounted estimate of future cash flows.
Goodwill	Goodwill represents the difference between the total purchase price and the fair value of identifiable assets and liabilities acquired in business acquisitions. In assessing the potential for impairment of goodwill, management uses the most current actual and forecasted operating data available and current market-based assumptions in accordance with the criteria in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 350. The Company has identified four reporting units: (1) Flavors, (2) Fragrance Compounds, (3) Fragrance Ingredients and (4) Cosmetic Actives Ingredients. These reporting units were determined based on the level at which the performance is measured and reviewed by segment management. The Company performs an annual goodwill impairment test for the Flavors, Fragrance Compounds, Fragrance Ingredients and Cosmetic Actives Ingredients reporting units by assessing the fair value of the reporting units based on discounted cash flows. If a reporting unit’s carrying amount exceeds its fair value, the Company will record an impairment charge based on that difference, and the impairment charge will be limited to the amount of goodwill allocated to that reporting unit. In January 2017, the FASB issued an amendment to the Goodwill Impairment guidance which eliminates Step 2 from the goodwill impairment test. Effective fiscal year 2017, the Company adopted the new guidance and no longer performs the annual goodwill impairment test using the two-step approach. The Company completed its annual goodwill impairment test as of November 30, 2017 , which indicated no impairment of goodwill, as the estimated fair values substantially exceeded the carrying values of each of these reporting units.
Income Taxes	The Company accounts for taxes under the asset and liability method. Under this method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized as income in the period in which such change is enacted. Future tax benefits are recognized to the extent that the realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes may not be realized. The Company recognizes uncertain tax positions that it has taken or expects to take on a tax return. Pursuant to accounting requirements, the Company first determines whether it is “more likely than not” its tax position will be sustained if the relevant tax authority were to audit the position with full knowledge of all the relevant facts and other information. For those tax positions that meet this threshold, the Company measures the amount of tax benefit based on the largest amount of tax benefit that it has a greater than 50% chance of realizing in a final settlement with the relevant authority. Those tax positions failing to qualify for initial recognition are recognized in the first interim period in which they meet the more likely than not standard. The Company maintains a cumulative risk portfolio relating to all of its uncertainties in income taxes in order to perform this analysis, but the evaluation of its tax positions requires significant judgment and estimation in part because, in certain cases, tax law is subject to varied interpretation, and whether a tax position will ultimately be sustained may be uncertain. Interest and penalties related to unrecognized tax benefits are recognized as a component of income tax expense.
Retirement Benefits	Current service costs of retirement plans and postretirement health care and life insurance benefits are accrued. Prior service costs resulting from plan improvements are amortized over periods ranging from 10 to 20 years.
Financial Instruments	Derivative financial instruments are used to manage interest and foreign currency exposures. The gain or loss on the hedging instrument is recorded in earnings at the same time as the transaction being hedged is recorded in earnings. The associated asset or liability related to the open hedge instrument is recorded in Prepaid expenses and Other current assets or Other current liabilities, as applicable. The Company records all derivative financial instruments on the balance sheet at fair value. Changes in a derivative’s fair value are recognized in earnings unless specific hedge criteria are met. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in Net income. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in Accumulated other comprehensive income ("AOCI") in the accompanying Consolidated Balance Sheet and are subsequently recognized in Net income when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges, if any, are recognized as a charge or credit to earnings.
Software Costs	The Company capitalizes direct internal and external development costs for certain significant projects associated with internal-use software and amortizes these costs over 7 years. Neither preliminary evaluation costs nor costs associated with the software after implementation are capitalized. Costs related to projects that are not significant are expensed as incurred.
Shipping and Handling Costs	Net sales include shipping and handling charges billed to customers. Cost of goods sold includes all costs incurred in connection with shipping and handling.
Net Income Per Share	Net income per share is based on the weighted average number of shares outstanding. A reconciliation of shares used in the computations of basic and diluted net income per share is as follows: December 31, (SHARES IN THOUSANDS) 2017 2016 2015 Basic 79,070 79,648 80,449 Assumed dilution under stock plans 300 333 442 Diluted 79,370 79,981 80,891
Stock-Based Compensation	Compensation cost of all stock-based awards is measured at fair value on the date of grant and recognized over the service period for which awards are expected to vest. The cost of such stock-based awards is principally recognized on a straight-line attribution basis over their respective vesting periods, net of estimated forfeitures.
New Accounting Standards	Accounting Pronouncements In February 2018, FASB issued amendments to the Income Statement - Reporting Comprehensive Income guidance which allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act, in addition to requiring certain disclosures about stranded tax effects. This guidance is effective for periods beginning after December 15, 2018, with an election to adopt early. The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In August 2017, FASB issued amendments to the Derivatives and Hedging guidance which eliminates the requirement to separately measure and present hedge ineffectiveness and aligns the presentation of hedge gains and losses with the underlying hedge item. This guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The amended presentation and disclosure requirements should be applied prospectively while the amendments to cash flow and net investment hedge relationships should be applied on a modified retrospective basis . The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In May 2017, the FASB issued amendments to the Compensation - Stock Compensation guidance which clarifies changes to the terms or conditions of a share-based payment award that require an entity to apply modification accounting. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted. The Company does not expect this guidance to have an impact on its Consolidated Financial Statements as it is not the Company's practice to modify the terms or conditions of a share-based payment award after it has been granted. In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires employers who present a measure of operating income in their statement of income to include only the service cost component of net periodic pension cost and postretirement costs in operating expenses. This guidance is effective, and should be applied retrospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The Company will adopt this standard on January 1, 2018, and expects the impact that this guidance will have on its Consolidated Statement of Comprehensive Income will be an increase in operating expenses of approximately $30 million and $15 million for the fiscal years 2017 and 2016, respectively. There will be no impact to Net income or Net Income per share in either period. The new guidance also limits the amount of net periodic benefit cost eligible for capitalization to assets. The new guidance permits only the service cost component of net periodic benefit cost to be eligible for capitalization. In January 2017, the FASB issued amendments to the Business Combination guidance which clarifies the definition of a business in order to assist companies when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance will be effective prospectively for annual and interim periods beginning after December 15, 2017. The Company will apply this guidance for transactions occurring after the effective date. In October 2016, the FASB issued authoritative guidance which allows for the immediate recognition of current and deferred income tax impact on intra-entity asset transfers, excluding inventory. The Company adopted this guidance in the first quarter of fiscal year 2017 and accordingly, recorded a cumulative-effect adjustment to Retained earnings that reduced Other assets and adjusted Deferred income taxes by a net amount of approximately $34 million . In August 2016, the FASB issued authoritative guidance which requires changes to the classification of certain activities within the statement of cash flows. This guidance will be effective for annual and interim periods beginning after December 15, 2017. Early adoption will be permitted for all entities. The Company does not expect this adoption to have a significant impact on its Consolidated Statement of Cash Flows. In June 2016, the FASB issued authoritative guidance which requires issuers to measure expected credit losses for financial assets based on historical experience, current conditions and reasonable and supportable forecasts. As such, an entity will use forward-looking information to estimate credit losses. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements, but does not expect this guidance to have a material impact on its consolidated financial statements. In March 2016, the FASB issued authoritative guidance which requires changes to several aspects of the accounting for share-based payment transactions, including the treatment of income tax consequences, classification of awards as either equity or liabilities, and classification of certain items on the statement of cash flows. This guidance was effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017. The standard requires that employee taxes paid when an employer withholds shares be presented in the Consolidated Statement of Cash Flows as a financing activity instead of an operating activity. The Company adopted this change retrospectively. The adoption resulted in an $11.8 million , $13.4 million and $22.9 million reclassification from Net cash provided by operating activities to Net cash provided by financing activities on the Consolidated Statement of Cash Flows as of December 31, 2017, 2016 and 2015, respectively. In addition, the standard requires that excess tax benefits presented in the Consolidated Statement of Cash Flows be classified as an operating activity instead of a financing activity. The Company adopted this change retrospectively. The adoption resulted in a $3.3 million , $4.7 million and $12.1 million reclassification from Net cash provided by financing activities to Net cash provided by operating activities on the Consolidated Statement of Cash Flows as of December 31, 2017, 2016 and 2015, respectively. The standard also requires all excess tax benefits/deficiencies be recognized as income tax expense/benefit in the Consolidated Statement of Comprehensive Income. This guidance has been applied prospectively. This change resulted in a $3.3 million benefit to income tax expense for the year ended December 31, 2017. For 2016, benefits of $5.3 million were recognized in equity. Additionally, the standard allows the Company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to be forfeited or account for forfeitures as they occur. The Company has elected to continue to account for forfeitures using an estimate of awards expected to be forfeited. In February 2016, the FASB issued authoritative guidance which requires changes to the accounting for leases. The new guidance establishes a new lease accounting model, that requires entities to record assets and liabilities related to leases on the balance sheet for certain types of leases. The guidance will be effective for annual and interim periods beginning after December 15, 2018. The Company expects to adopt this guidance effective December 30, 2018 and that the adoption of this guidance will result in significant increases to assets and liabilities on its Consolidated Balance Sheet. The Company is still evaluating the impact of this guidance on its Consolidated Statement of Comprehensive Income. The Company has begun to evaluate the nature of its leases and has compiled preliminary analysis of the type and location of its leases. The Company expects that the significant portion of its leases will relate to property but with additional leases in existence that relate to vehicles and machinery.
