Consolidated Financial Statemen

Consolidated Financial Statements	3 Months Ended

Accounting Policies [Abstract]
Consolidated Financial Statements	f Presentation These interim statements and related management’s discussion and analysis should be read in conjunction with the Consolidated Financial Statements and the related notes and management’s discussion and analysis of results of operations, liquidity and capital resources included in our 2017 Annual Report on Form 10-K (“ 2017 Form 10-K”). These interim statements are unaudited. The year-end balance sheet data included in this Form 10-Q was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States of America. We have historically operated and continue to operate on a 52/53 week fiscal year ending on the Friday closest to the last day of the quarter. For ease of presentation, March 31 and December 31 are used consistently throughout this Form 10-Q and these interim financial statements and related notes to represent the period-end dates. For the 2018 and 2017 quarters, the actual closing dates were March 30 and March 31, respectively. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. When used herein, the terms “IFF,” the “Company,” “we,” “us” and “our” mean International Flavors & Fragrances Inc. and its consolidated subsidiaries. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Reclassifications and Revisions Certain prior year amounts have been reclassified and revised to conform to current year presentation. As discussed below and in conformity with the Financial Accounting Standards Board's ("FASB") amendments to the Compensation - Retirement Benefits guidance, the Company has reclassified certain components of net periodic benefit expense (income) to Other income (expense), net. Additionally, approximately $5.4 million of expense was recorded during the first quarter of 2017 for a tax assessment relating to prior periods. The Consolidated Statement of Cash Flows for the three months ended March 31, 2017 has been revised to properly reclassify $3.2 million from Net cash used in financing activities to reduce Net cash provided by operating activities, and has also been revised to correctly state the amount of Cash paid for interest, net of amounts capitalized, for the three months ended March 31, 2017. These adjustments were not material to the current or previously-issued financial statements. 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. In the fourth quarter of 2017, the Company recorded approximately $139.2 million in charges related to the impact of the Tax Act. 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 amount recorded by the Company in the fourth quarter of 2017 was provisional and will continue to be adjusted during 2018. The impact of the Tax Act is expected to be finalized no later than the fourth quarter of 2018. The aforementioned guidance and additional information regarding the Tax Act may also impact the Company's 2018 effective income tax rate, exclusive of any adjustment to the provisional charge. Any material revisions in our computations could adversely affect our cash flows and results of operations. During the first quarter of 2018, the Company recorded an additional charge of $0.6 million to adjust an accrual related to withholding taxes on planned repatriations. 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 sales 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 decreased approximately $11.0 million for the three months ended March 31, 2018 compared to a decrease of approximately $27.1 million for the three months ended March 31, 2017 . The cost of participating in these programs was immaterial to our results in all periods. Recent Accounting Pronouncements In February 2018, FASB issued amendments to the Income Statement - Reporting Comprehensive Income guidance which allows for 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 may 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 are to be applied prospectively while the amendments to cash flow and net investment hedge relationships are to be applied on a modified retrospective basis . The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements, but does not expect this guidance to have a material impact 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 for the current year. The Company has determined that this guidance does not 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 as required, has been applied on a full retrospective basis. The impact of the adoption of this standard on January 1, 2018, was a decrease in operating profit of $7.3 million for the three months ended March 31, 2017 , and an increase in income within Other (income) expense, net, as presented in the Company's Consolidated Statement of Income and Comprehensive Income. There was no impact to Net income or Net Income per share in either period. See Note 10 of the Consolidated Financial Statements for further details. 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. The Company applied the practical expedient that permits the use of amounts previously disclosed as the basis for retrospective application and, as provided under the practical expedient, has not presented the income statement impact based on the capitalization of the applicable costs. 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 is effective for the current year, and the Company has determined that this adoption does not 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 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, the first day of the Company’s 2019 fiscal year, 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 Income and Comprehensive Income and Consolidated Statement of Cash Flows. The Company has begun to evaluate the nature of its leases and has compiled a preliminary analysis of the type and location of its leases. The Company expects that the significant portion of its lease liabilities will relate to property, with additional lease and corresponding right of use assets in existence that relate to vehicles and machinery. Adoption of ASC Topic 606, Revenue from Contracts with Customers 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 is recognized to reflect 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. 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 new Revenue Standard became effective for annual reporting periods beginning after December 15, 2017, and the Company has adopted the new revenue standard using the modified retrospective approach on December 30, 2017, the first day of the Company’s 2018 fiscal year. The Company creates and manufactures flavors and fragrances. Approximately 90% of its products, principally Flavors compounds and Fragrances compounds, are customized to customer specifications and have no alternative use other than the sale to the specific customer (“Compounds products”). The remaining revenue is derived largely from Fragrance Ingredients products that, generally, are commodity products with alternative uses and not customized (“Ingredients products”). With respect to the vast majority of the Company’s contracts for Compounds products, the Company currently recognizes revenue on the transfer of control of the product at a point in time as the Company does not have an “enforceable right to payment for performance to date” (as set out in the Revenue Standard). With respect to a small number of contracts for the sale of Compounds, the Company has an “enforceable right to payment for performance to date” and as the products do not have an alternative use, the Company recognizes revenue for these contracts over time and records a contract asset using the output method. The output method recognizes revenue on the basis of direct measurements of the value to the customer of the goods or services transferred to date relative to the remaining goods or services promised under the contract. With respect to the Company’s contracts related to Ingredients products, the Company currently recognizes revenue on the transfer of control of the product at a point in time as such products generally have alternative uses and the Company does not have an “enforceable right to payment for performance to date.” As the Company adopted the Revenue Standard using the modified retrospective method effective the first day of its 2018 fiscal year, results for its 2018 fiscal year are presented under the Revenue Standard while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC Topic 605, which required that revenue was accounted for when the earnings process was complete. The Company recorded a net increase to retained earnings of $2.1 million as of the first day of its 2018 fiscal year due to the cumulative impact of adopting the Revenue Standard. In connection with the adjustment to retained earnings, the Company also recorded an increase of $4.4 million in contract assets (which are included in Prepaid expenses and other assets), a decrease of $1.7 million in inventory, and an increase in taxes payable of $0.6 million . The impact to revenues, gross profit and net income for three months ended March 31, 2018 were reductions of $0.6 million , $0.4 million and $0.3 million , respectively, as a result of applying the Revenue Standard as compared to the amounts that would have been recognized under ASC Topic 605. Revenue Recognition The Company recognizes revenue when control of the promised goods is transferred to its customers in an amount that reflects the consideration it expects to be entitled to in exchange for those goods. Sales, value add, and other taxes the Company collects are excluded from revenues. The Company receives payment in accordance with standard customer terms. The following table presents the Company's revenues disaggregated by business unit: Three Months Ended March 31, (DOLLARS IN THOUSANDS) 2018 2017 (a) Flavor Compounds 449,019 406,164 Fragrance Compounds Consumer Fragrances 280,238 252,695 Fine Fragrances 98,395 87,705 Fragrance Ingredients 103,276 81,729 Total revenues 930,928 828,293 _______________________ (a) Prior period amounts have not been adjusted based on the modified retrospective method. The following table presents our revenues disaggregated by region, based on the region of our customers: Three Months Ended March 31, (DOLLARS IN THOUSANDS) 2018 2017 (a) Europe, Africa and Middle East 309,312 257,684 Greater Asia 243,557 222,820 North America 241,146 218,828 Latin America 136,913 128,961 Total revenues 930,928 828,293 _______________________ (a) Prior period amounts have not been adjusted based on the modified retrospective method. Flavors and Fragrances Compounds Revenues The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms (which vary by customer) are identified, the contract has commercial substance, and collectability of consideration is probable. Consistent with our past practice, the amount of revenue recognized is adjusted at the time of sale for expected discounts and rebates (“Variable Consideration”). The Company generates revenues primarily by manufacturing customized Flavor compounds and Fragrance compounds for the exclusive use of our customers. The Company combines the shipment of goods with their manufacture to account for both shipment and manufacture as the sole performance obligation. With respect to the vast majority of the Company’s contracts for Compounds products , the Company recognizes a sale at the point in time when it ships the product from its manufacturing facility to its customer, as this is the time when control of the goods has transferred to the customer. The amount of consideration received and revenue recognized is impacted by the Variable Consideration the Company has agreed with its customers. The Company estimates Variable Consideration amounts for each customer based on the specific agreement, an analysis of historical volumes and the current activity with that customer. The Company reassesses its estimates of Variable Consideration at each reporting date throughout the contract period and updates the estimate until the uncertainty is resolved. During the current period, changes to estimates of Variable Consideration have been immaterial. With respect to a small number of contracts for the sale of Compounds products, the Company recognizes revenue over time as it manufactures customized compounds that do not have an alternative use and for which the contracts provide the Company with an enforceable right to payment, including a reasonable profit, at all times during the contract term commencing with the manufacturing of the goods. When revenue is recognized over time, the amount of revenue recognized is based on the extent of progress towards completion of the promised goods. The Company generally uses the output method to measure progress for its contracts as this method reflects the transfer of goods to the customer. Once customization begins, the manufacturing process is generally completed within a two week period. Due to the short time frame for production, there is little estimation uncertainty in the process. In addition, due to the customized nature of our products, our returns are not material. Fragrance Ingredients Revenues The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms (which vary by customer) are identified, the contract has commercial substance, and collectability of consideration is probable. The Company generates revenues primarily by manufacturing Ingredients products for the use of our customers. The Company combines the shipment of goods with their manufacture to account for both shipment and manufacture as the sole performance obligation. Generally, the Company recognizes a sale at the time when it ships the product from their manufacturing facility to their customer, as this is the point when control of the goods or services has transferred to the customer. The amount of consideration received and revenue recognized is impacted by discounts offered to its customers. The Company estimates discounts based on an analysis of historical experience and current activity. The Company assesses its estimates of discounts at each reporting date throughout the contract period and updates its estimates until the uncertainty has been resolved. During the current period, changes to estimates of discounts have been immaterial. Contract Asset and Accounts Receivable The following table reflects the changes in our contract assets and accounts receivable for the three months ended March 31, 2018 and December 31, 2017 : (DOLLARS IN THOUSANDS) March 31, 2018 At adoption Receivables (included in Trade receivables) 747,862 677,055 Contract asset - Short term 3,839 4,449

Earnings Per Share [Abstract]
Net Income Per Share	NET INCOME PER SHARE Net income per share is based on the weighted average number of shares outstanding. A reconciliation of the shares used in the computation of basic and diluted net income per share is as follows: Three Months Ended March 31, (SHARES IN THOUSANDS) 2018 2017 Basic 79,018 79,098 Assumed dilution under stock plans 375 311 Diluted 79,393 79,409 There were no stock options or stock-settled appreciation rights (“SSARs”) excluded from the computation of diluted net income per share for the three months ended March 31, 2018 and 2017 . The Company has issued shares of purchased restricted common stock and purchased restricted common stock units (collectively “PRSUs”) which contain rights to nonforfeitable dividends while these shares are outstanding and thus are considered participating securities. Such securities are required to be included in the computation of basic and diluted earnings per share pursuant to the two-class method. The Company did not present the two-class method since the difference between basic and diluted net income per share for both unrestricted common shareholders and PRSU shareholders was less than $0.01 per share for each period presented, and the number of PRSUs outstanding as of March 31, 2018 and 2017 was immaterial. Net income allocated to such PRSUs was $0.3 million for both the three months ended March 31, 2018 and 2017 .

Business Combinations [Abstract]
Acquisitions	Pure On April 7, 2017, the Company completed the acquisition of 100% of the outstanding shares of Columbia PhytoTechnology, LLC d/b/a PowderPure ("PowderPure"), a privately-held flavors company with facilities in North America. The acquisition was accounted for under the purchase method. PowderPure was acquired to expand expertise in, and product offerings of, clean label solutions within the Flavors business. The Company paid approximately $54.6 million , including $0.4 million of cash acquired for this acquisition, which was funded from existing resources. Additionally, the Company recorded an accrual of approximately $1.4 million representing the estimate at acquisition of additional contingent consideration payable to the former owners of PowderPure (the maximum earnout payable is $10 million upon satisfaction of certain performance metrics). The purchase price exceeded the preliminary fair value of existing net assets by approximately $48.0 million . The excess was allocated principally to identifiable intangible assets including approximately $27.5 million to proprietary technology, approximately $4.5 million to trade name, approximately $0.8 million to customer relationships, and approximately $15.2 million of goodwill which is deductible for tax purposes. Goodwill is the excess of the purchase price over the fair value of net assets acquired and represents the value the Company expects to achieve from its increased exposure to clean label products within the existing Flavors business. The intangible assets are being amortized over the following estimated useful lives: proprietary technology, 14 years; trade name, 14 years; and customer relationships, 2 years. The purchase price allocation was completed in the first quarter of 2018. No material adjustments have been made to the purchase price allocation since the preliminary valuation performed in the second quarter of 2017. The estimated amount of the contingent consideration payable was revised during the first quarter of 2018 and resulted in a decrease in administrative expense of approximately $0.6 million . No pro forma financial information for 2017 is presented as the acquisition was not material to the consolidated financial statements. Fragrance Resources On January 17, 2017, the Company completed the acquisition of 100% of the outstanding shares of Fragrance Resources, Inc., Fragrance Resources GmbH, and Fragrance Resources SAS (collectively "Fragrance Resources"), a privately-held fragrance company with facilities in Germany, North America, France, and China. The acquisition was accounted for under the purchase method. Fragrance Resources was acquired to strengthen the North American and German Fragrances business. The Company paid approximately € 143.4 million (approximately $151.9 million ) including approximately € 13.7 million (approximately $14.4 million ) of cash acquired for this acquisition, which was funded from existing resources including use of its revolving credit facility. Of the total paid, approximately € 142.0 million (approximately $150.5 million ) was paid at closing and an additional € 1.4 million (approximately $1.5 million ) was paid in connection with the finalization of the working capital adjustment. The purchase price exceeded the fair value of existing net assets by approximately $122.0 million . The excess was allocated principally to identifiable intangible assets including approximately $51.7 million related to customer relationships, approximately $13.6 million related to proprietary technology and trade name, and approximately $ 72.0 million of goodwill (which is not deductible for tax purposes) and approximately $15.3 million of net deferred tax liability. Goodwill is the excess of the purchase price over the fair value of net assets acquired and represents synergies from the addition of Fragrance Resources to the Company's existing Fragrances business. The intangible assets are being amortized over the following estimated useful lives: trade name, 2 years; proprietary technology, 5 years; and customer relationships, 12 - 16 years. The purchase price allocation was finalized in the fourth quarter of 2017. Certain measurement period adjustments were made subsequent to the initial purchase price allocation including adjustments related to the finalization of the purchase price, the allocation of certain intangibles and the calculation of applicable deferred taxes. The additional amortization of intangibles required as a result of the measurement period adjustments was not material. No pro forma financial information for 2016 is presented as the acquisition was not material to the consolidated financial statements.

Restructuring and Related Activities [Abstract]
Restructuring and Other Charges, Net	RESTRUCTURING AND OTHER CHARGES, NET 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, the Company expects to optimize its global footprint and simplify its 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 $21.3 million of charges related to personnel costs and lease termination costs through the first quarter of 2018 , with the remainder of the personnel related and other costs expected to be recognized by the end of 2018. The Company recorded $0.7 million and $10.1 million of charges related to personnel costs and lease termination costs during the three months ended March 31, 2018 and 2017, respectively. The Company made payments of $1.7 million related to severance in 2018 . 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. Changes in employee-related restructuring liabilities during the three months ended March 31, 2018 , were as follows: (DOLLARS IN THOUSANDS) Employee-Related Costs Other Total Balance at December 31, 2017 $ 7,539 $ 418 $ 7,957 Additional charges (reversals), net 717 — 717 Non-cash charges — — — Payments (1,696 ) — (1,696 ) Balance at March 31, 2018 $ 6,560 $ 418 $ 6,978

Income Tax Disclosure [Abstract]
Income Taxes	U.S. Tax Reform In the fourth quarter of 2017, the Company recorded approximately $139.2 million in charges related to the impact of the Tax Act. 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 amount recorded by the Company in the fourth quarter of 2017 was provisional and will continue to be adjusted during 2018. The impact of the Tax Act is expected to be finalized no later than the fourth quarter of 2018. The aforementioned guidance and additional information regarding the Tax Act may also impact the Company's 2018 effective income tax rate, exclusive of any adjustment to the provisional charge. Any material revisions in our computations could adversely affect our cash flows and results of operations. During the first quarter of 2018, the Company recorded an additional charge of $0.6 million to adjust an accrual related to withholding taxes on planned repatriations. Uncertain Tax Positions At March 31, 2018 , the Company had $28.5 million of unrecognized tax benefits recorded in Other liabilities and $5 million in Other current liabilities. If these unrecognized tax benefits were recognized, the effective tax rate would be affected. At March 31, 2018 , the Company had accrued interest and penalties of $2.3 million classified in Other liabilities and $0.5 million in Other current liabilities. As of March 31, 2018 , the Company’s aggregate provisions for uncertain tax positions, including interest and penalties, was $36.3 million associated with various tax positions asserted in various jurisdictions, none of which is individually material. The Company regularly repatriates a portion of current year earnings from select non–U.S. subsidiaries. No provision is made for additional taxes on undistributed earnings of subsidiary companies that are intended and planned to be indefinitely invested in such subsidiaries. We intend to, and have plans to, reinvest these earnings indefinitely in our foreign subsidiaries to fund local operations and/or capital projects. The Company has ongoing income tax audits and legal proceedings which are at various stages of administrative or judicial review. In addition, the Company has open tax years with various taxing jurisdictions that range primarily from 2008 to 2017 . Based on currently available information, we do 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 our financial position. The Company also has other ongoing tax audits and legal proceedings that relate to indirect taxes, such as value-added taxes, sales and use taxes and property taxes, which are discussed in Note 13. Effective Tax Rate The effective tax rate for the three months ended March 31, 2018 was 18.5% compared with 16.4% for the three months ended March 31, 2017 . The year-over-year increase was largely due to the impact of U.S. tax reform and increased loss provisions, partially offset by mix of earnings, a lower cost of repatriation (principally due to tax reform) and the release of a State valuation allowance that related to prior years.

During the three months ended March 31, 2018 , no contributions were made to the qualified U.S. pension plans, $3.3 million of contributions were made to the non-U.S. pension plans, and $1.1 million of benefit payments were made with respect to the Company's non-qualified U.S. pension plan. Expense recognized for postretirement benefits other than pensions included the following components: Three Months Ended March 31, (DOLLARS IN THOUSANDS) 2018 2017 Service cost for benefits earned $ 195 $ 221 Interest cost on projected benefit obligation 654 588 Net amortization and deferrals (1,189 ) (1,046 ) Total postretirement benefit income $ (340 ) $ (237 ) The components of net periodic benefit (income) other than the service cost component are included in Other (income) expense, net in the Consolidated Statement of Income and Comprehensive Income. Beginning in 2018, under the revised FASB guidance adopted in the first quarter, only the service cost component of net periodic benefit (income) cost is a component of operating profit in the Consolidated Statements of Income and Comprehensive Income and the other components of net periodic benefit cost are now included in Other (income), net. As a result of this change, Other income increased by approximately $6.1 million and $7.3 million in the three months ended March 31, 2018 and 2017 , respectively, compared to what the Other (income) expense, net would have been under the previous method. The retroactive $7.3 million reduction in operating profit for the three months ended March 31, 2017 was reflected as a $1.6 million increase in cost of goods sold, a $2.4 million increase in research and development expenses, and a $3.3 million increase in selling and administrative expenses. The Company expects to contribute approximately $5.0 million to its postretirement benefits other than pension plans during 2018 . In the three months ended March 31, 2018 , $0.9 million of contributions were made.

Financial Instruments

Financial Instruments	3 Months Ended

Investments, All Other Investments [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 as discussed in Note 14 of our 2017 Form 10-K. 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 March 31, 2018 . The principal amounts and the estimated fair values of financial instruments at March 31, 2018 and December 31, 2017 consisted of the following: March 31, 2018 December 31, 2017 (DOLLARS IN THOUSANDS) Principal Fair Principal Fair Cash and cash equivalents (1) $ 305,276 $ 305,276 $ 368,046 $ 368,046 Credit facilities and bank overdrafts (2) 30,589 30,589 7,993 7,993 Commercial paper (2) 29,926 29,926 — — Long-term debt: (3) Senior notes - 2007 250,000 285,062 250,000 293,232 Senior notes - 2013 300,000 297,535 300,000 304,219 Euro Senior notes - 2016 615,400 642,921 594,400 627,782 Senior notes - 2017 500,000 497,689 500,000 525,906 _______________________ (1) The carrying amount of cash and cash equivalents approximates fair value due to the short maturity of those instruments. (2) The carrying amount 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 three months ended March 31, 2018 and the year ended December 31, 2017 , 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 accumulated other comprehensive income (loss) ("AOCI") where they will remain until the net investments in the Company's European subsidiaries are divested. The outstanding forward currency contracts have remaining maturities of less than one year . Three of these forward currency contracts matured during the three months ended March 31, 2018 . 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 three months ended March 31, 2018 and the year ended December 31, 2017 , 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. The Company maintains various interest rate swap agreements that effectively convert 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 three months ended March 31, 2018 and 2017 . The Company has previously entered into interest rate swap agreements to hedge the anticipated issuance of fixed-rate debt, which are designated as cash flow hedges. The amount of gains and losses realized upon termination of these agreements is amortized over the life of the corresponding debt issuance. The following table shows the notional amount of the Company’s derivative instruments outstanding as of March 31, 2018 and December 31, 2017 : (DOLLARS IN THOUSANDS) March 31, 2018 December 31, 2017 Forward currency contracts $ 777,134 $ 896,947 Interest rate swaps $ 150,000 $ 150,000 The following tables show the Company’s derivative instruments measured at fair value (Level 2 of the fair value hierarchy), as reflected in the Consolidated Balance Sheet as of March 31, 2018 and December 31, 2017 : March 31, 2018 (DOLLARS IN THOUSANDS) Fair Value of Fair Value of Total Fair Derivative assets (a) Foreign currency contracts $ 1,053 $ 6,307 $ 7,360 Derivative liabilities (b) Foreign currency contracts $ 6,425 $ 743 $ 7,168 Interest rate swaps 3,169 — 3,169 Total Derivative liabilities $ 9,594 $ 743 $ 10,337 December 31, 2017 (DOLLARS IN THOUSANDS) Fair Value of Fair Value of Total Fair Derivative assets (a) Foreign currency contracts $ 1,159 $ 3,978 $ 5,137 Derivative liabilities (b) Foreign currency contracts $ 7,842 $ 4,344 $ 12,186 Interest rate swaps 1,369 — 1,369 Total Derivative liabilities $ 9,211 $ 4,344 $ 13,555 _______________________ (a) Derivative assets are recorded to Prepaid expenses and other current assets in the Consolidated Balance Sheet.

The ineffective portion of the above noted cash flow hedges and net investment hedges were not material during the three months ended March 31, 2018 and 2017 . The Company expects that approximately $6.4 million (net of tax) of derivative loss included in AOCI at March 31, 2018 , based on current market rates, will be reclassified into earnings within the next 12 months. The majority of this amount will vary due to fluctuations in foreign currency exchange rates.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	arantees 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 March 31, 2018 , we 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 March 31, 2018 . 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 $15.9 million as of March 31, 2018 . Lines of Credit The Company has various lines of credit which are available to support its ongoing business operations. As of March 31, 2018 , we had available lines of credit of approximately $106.4 million with various financial institutions, in addition to the $950 million of capacity under the Credit Facility discussed in Note 9 of our 2017 Form 10-K. There were no material amounts drawn down pursuant to these lines of credit as of March 31, 2018 . 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 will be 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 will be 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 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 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 $70 million as of March 31, 2018 . Zhejiang Ingredients plant In the fourth quarter of 2017, the Company concluded discussions with the government regarding the relocation of its Fragrance Ingredients plant in Zhejiang 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. No additional amounts have been received in the first quarter of 2018 . The net book value of the current plant was approximately $25 million as of March 31, 2018 . 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 $160 million as of March 31, 2018 . 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 $31.6 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 an FDA-mandated product recall. As of March 31, 2018 , the Company had recorded total charges of approximately $17.5 million with respect to this claim, of which $5.0 million was recorded in the three months ended March 31, 2018 . The Company settled the claim with the customer for a total of $16.0 million , of which $13.0 million was paid during the three months ended March 31, 2018 . The remaining accrual of approximately $1.5 million represents management's best estimate of losses related to claims from other affected parties. 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 $12 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.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS On May 7, 2018, the Company entered into a definitive agreement and plan of merger to acquire Frutarom Industries Ltd. (“Frutarom”). Frutarom is a flavors, savory solutions and natural ingredients company with production and development centers on six continents, that is traded on the Tel Aviv and London Stock Exchanges. The transaction is targeted to close in six to nine months, has been unanimously approved by the Boards of Directors of both companies and is subject to approval by Frutarom shareholders, clearance by the relevant regulatory authorities and other customary closing conditions. Under the terms of the merger agreement, for each share of outstanding stock, Frutarom shareholders will receive $71.19 in cash and 0.2490 of a share of the Company's common stock, which, based on the 10-day volume weighted average price for the Company's common stock for the period ending May 4, 2018, represents a total value of $106.25 per share. The transaction is valued at approximately $7.1 billion , including the assumption of approximately $681 million of Frutarom's net debt, which the Company intends to refinance or repay concurrent with the closing of the transaction. The Company expects to fund the cash portion of the merger consideration with cash on hand, new mid-term and long-term bonds, term loans and an issuance of equity. In connection with these financings, the Company also expects to pay its outstanding $250 million of its Senior Notes 2007 and the associated make-whole payments of approximately $35 million . Based on the number of Frutarom shares of common stock outstanding as of May 4, 2018, the Company anticipates issuing approximately 18.9% of its issued and outstanding shares of common stock as the stock portion of merger consideration. On May 7, 2018, the Company entered into a bridge facility commitment letter pursuant to which Morgan Stanley Senior Funding, Inc. committed, subject to customary conditions, to provide up to $5.5 billion under a 364-day senior unsecured bridge term loan credit facility to finance the cash portion of the merger consideration if the Company has not completed its anticipated financing transactions prior to the consummation of the merger.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These interim statements and related management’s discussion and analysis should be read in conjunction with the Consolidated Financial Statements and the related notes and management’s discussion and analysis of results of operations, liquidity and capital resources included in our 2017 Annual Report on Form 10-K (“ 2017 Form 10-K”). These interim statements are unaudited. The year-end balance sheet data included in this Form 10-Q was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States of America. We have historically operated and continue to operate on a 52/53 week fiscal year ending on the Friday closest to the last day of the quarter. For ease of presentation, March 31 and December 31 are used consistently throughout this Form 10-Q and these interim financial statements and related notes to represent the period-end dates. For the 2018 and 2017 quarters, the actual closing dates were March 30 and March 31, respectively. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. When used herein, the terms “IFF,” the “Company,” “we,” “us” and “our” mean International Flavors & Fragrances Inc. and its consolidated subsidiaries.
Reclassifications and Revisions	Reclassifications and Revisions Certain prior year amounts have been reclassified and revised to conform to current year presentation. As discussed below and in conformity with the Financial Accounting Standards Board's ("FASB") amendments to the Compensation - Retirement Benefits guidance, the Company has reclassified certain components of net periodic benefit expense (income) to Other income (expense), net. Additionally, approximately $5.4 million of expense was recorded during the first quarter of 2017 for a tax assessment relating to prior periods. The Consolidated Statement of Cash Flows for the three months ended March 31, 2017 has been revised to properly reclassify $3.2 million from Net cash used in financing activities to reduce Net cash provided by operating activities, and has also been revised to correctly state the amount of Cash paid for interest, net of amounts capitalized, for the three months ended March 31, 2017. These adjustments were not material to the current or previously-issued financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2018, FASB issued amendments to the Income Statement - Reporting Comprehensive Income guidance which allows for 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 may 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 are to be applied prospectively while the amendments to cash flow and net investment hedge relationships are to be applied on a modified retrospective basis . The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements, but does not expect this guidance to have a material impact 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 for the current year. The Company has determined that this guidance does not 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 as required, has been applied on a full retrospective basis. The impact of the adoption of this standard on January 1, 2018, was a decrease in operating profit of $7.3 million for the three months ended March 31, 2017 , and an increase in income within Other (income) expense, net, as presented in the Company's Consolidated Statement of Income and Comprehensive Income. There was no impact to Net income or Net Income per share in either period. See Note 10 of the Consolidated Financial Statements for further details. 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. The Company applied the practical expedient that permits the use of amounts previously disclosed as the basis for retrospective application and, as provided under the practical expedient, has not presented the income statement impact based on the capitalization of the applicable costs. 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 is effective for the current year, and the Company has determined that this adoption does not 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 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, the first day of the Company’s 2019 fiscal year, 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 Income and Comprehensive Income and Consolidated Statement of Cash Flows. The Company has begun to evaluate the nature of its leases and has compiled a preliminary analysis of the type and location of its leases. The Company expects that the significant portion of its lease liabilities will relate to property, with additional lease and corresponding right of use assets in existence that relate to vehicles and machinery. Adoption of ASC Topic 606, Revenue from Contracts with Customers 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 is recognized to reflect 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. 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 new Revenue Standard became effective for annual reporting periods beginning after December 15, 2017, and the Company has adopted the new revenue standard using the modified retrospective approach on December 30, 2017, the first day of the Company’s 2018 fiscal year. The Company creates and manufactures flavors and fragrances. Approximately 90% of its products, principally Flavors compounds and Fragrances compounds, are customized to customer specifications and have no alternative use other than the sale to the specific customer (“Compounds products”). The remaining revenue is derived largely from Fragrance Ingredients products that, generally, are commodity products with alternative uses and not customized (“Ingredients products”). With respect to the vast majority of the Company’s contracts for Compounds products, the Company currently recognizes revenue on the transfer of control of the product at a point in time as the Company does not have an “enforceable right to payment for performance to date” (as set out in the Revenue Standard). With respect to a small number of contracts for the sale of Compounds, the Company has an “enforceable right to payment for performance to date” and as the products do not have an alternative use, the Company recognizes revenue for these contracts over time and records a contract asset using the output method. The output method recognizes revenue on the basis of direct measurements of the value to the customer of the goods or services transferred to date relative to the remaining goods or services promised under the contract. With respect to the Company’s contracts related to Ingredients products, the Company currently recognizes revenue on the transfer of control of the product at a point in time as such products generally have alternative uses and the Company does not have an “enforceable right to payment for performance to date.” As the Company adopted the Revenue Standard using the modified retrospective method effective the first day of its 2018 fiscal year, results for its 2018 fiscal year are presented under the Revenue Standard while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC Topic 605, which required that revenue was accounted for when the earnings process was complete.
Revenue Recognition	The Company recognizes revenue when control of the promised goods is transferred to its customers in an amount that reflects the consideration it expects to be entitled to in exchange for those goods. Sales, value add, and other taxes the Company collects are excluded from revenues. The Company receives payment in accordance with standard customer terms. The following table presents the Company's revenues disaggregated by business unit: Three Months Ended March 31, (DOLLARS IN THOUSANDS) 2018 2017 (a) Flavor Compounds 449,019 406,164 Fragrance Compounds Consumer Fragrances 280,238 252,695 Fine Fragrances 98,395 87,705 Fragrance Ingredients 103,276 81,729 Total revenues 930,928 828,293 _______________________ (a) Prior period amounts have not been adjusted based on the modified retrospective method. The following table presents our revenues disaggregated by region, based on the region of our customers: Three Months Ended March 31, (DOLLARS IN THOUSANDS) 2018 2017 (a) Europe, Africa and Middle East 309,312 257,684 Greater Asia 243,557 222,820 North America 241,146 218,828 Latin America 136,913 128,961 Total revenues 930,928 828,293 _______________________ (a) Prior period amounts have not been adjusted based on the modified retrospective method. Flavors and Fragrances Compounds Revenues The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms (which vary by customer) are identified, the contract has commercial substance, and collectability of consideration is probable. Consistent with our past practice, the amount of revenue recognized is adjusted at the time of sale for expected discounts and rebates (“Variable Consideration”). The Company generates revenues primarily by manufacturing customized Flavor compounds and Fragrance compounds for the exclusive use of our customers. The Company combines the shipment of goods with their manufacture to account for both shipment and manufacture as the sole performance obligation. With respect to the vast majority of the Company’s contracts for Compounds products , the Company recognizes a sale at the point in time when it ships the product from its manufacturing facility to its customer, as this is the time when control of the goods has transferred to the customer. The amount of consideration received and revenue recognized is impacted by the Variable Consideration the Company has agreed with its customers. The Company estimates Variable Consideration amounts for each customer based on the specific agreement, an analysis of historical volumes and the current activity with that customer. The Company reassesses its estimates of Variable Consideration at each reporting date throughout the contract period and updates the estimate until the uncertainty is resolved. During the current period, changes to estimates of Variable Consideration have been immaterial. With respect to a small number of contracts for the sale of Compounds products, the Company recognizes revenue over time as it manufactures customized compounds that do not have an alternative use and for which the contracts provide the Company with an enforceable right to payment, including a reasonable profit, at all times during the contract term commencing with the manufacturing of the goods. When revenue is recognized over time, the amount of revenue recognized is based on the extent of progress towards completion of the promised goods. The Company generally uses the output method to measure progress for its contracts as this method reflects the transfer of goods to the customer. Once customization begins, the manufacturing process is generally completed within a two week period. Due to the short time frame for production, there is little estimation uncertainty in the process. In addition, due to the customized nature of our products, our returns are not material. Fragrance Ingredients Revenues The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties and payment terms (which vary by customer) are identified, the contract has commercial substance, and collectability of consideration is probable. The Company generates revenues primarily by manufacturing Ingredients products for the use of our customers. The Company combines the shipment of goods with their manufacture to account for both shipment and manufacture as the sole performance obligation. Generally, the Company recognizes a sale at the time when it ships the product from their manufacturing facility to their customer, as this is the point when control of the goods or services has transferred to the customer. The amount of consideration received and revenue recognized is impacted by discounts offered to its customers. The Company estimates discounts based on an analysis of historical experience and current activity. The Company assesses its estimates of discounts at each reporting date throughout the contract period and updates its estimates until the uncertainty has been resolved. During the current period, changes to estimates of discounts have been immaterial.
