Accounting Policies [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 2018 Annual Report on Form 10-K (“ 2018 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, September 30 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 2019 and 2018 quarters, the actual closing dates were September 27 and September 28 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. generally accepted accounting principles (“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. Accounts Receivable During 2019, the Company entered into certain factoring agreements in the U.S. and The Netherlands under which it can factor up to approximately $100 million in receivables. The new factoring agreements supplement the Company's existing factoring programs that are sponsored by certain customers. Under all of the arrangements, the Company sells the receivables on a non-recourse basis to unrelated financial institutions and accounts for the transactions as a sale of receivables. The applicable receivables are removed from the Company's Consolidated Balance Sheet when the cash proceeds are received by the Company. As of September 30, 2019 and December 31, 2018, the Company had removed approximately $204 million and $128 million of receivables, respectively. The impact on cash provided by operations from participating in these programs increased approximately $76 million for the nine months ended September 30, 2019 compared to a decrease of approximately $11 million for the nine months ended September 30, 2018 . The cost of participating in these programs was approximately $1.7 million and $0.8 million for the three months ended September 30, 2019 and 2018 , respectively, and $4.7 million and $2.7 million for the nine months ended September 30, 2019 and 2018 , respectively. Contract Assets 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.

The ASU allows for the use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for purposes of applying hedge accounting under ASC 815, Derivatives and Hedging. The Company applied this new guidance as of December 29, 2018, the first day of the Company’s 2019 fiscal year. The adoption of the guidance did not have a material impact on the Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal - Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force).” The ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans (Subtopic 715-20)", which modifies the disclosure requirements on company-sponsored defined benefit plans. The ASU is effective for fiscal years beginning after December 15, 2020 on a retrospective basis to all periods presented. Early adoption is permitted. The Company has determined that this guidance will not have an impact on its Consolidated Financial Statements and will have a minimal impact on its disclosures. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820)", which modifies, removes and adds certain disclosure requirements on fair value measurements. The ASU is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. The Company has determined that this guidance will not have an impact on its Consolidated Financial Statements, as the Company has no applicable fair value measurements that are affected by the guidance. In June 2018, the FASB issued ASU 2018-07, "Compensation - Stock Compensation (Topic 718)" intended to reduce cost and complexity and to improve financial reporting for nonemployee share-based payments. This guidance expands the scope of Topic 718, Compensation-Stock Compensation which currently only includes share-based payments to employees to include share-based payments issued to nonemployees for goods or services. The Company applied this new guidance as of December 29, 2018, the first day of the Company’s 2019 fiscal year. The adoption of the guidance did not have a material impact on the Consolidated Financial Statements. In February 2018, FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" 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. The guidance was effective as of December 29, 2018, the first day of the Company's fiscal year. The Company elected to not reclassify any stranded tax effects to retained earnings. In August 2017, FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" 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, and as required, has been applied on a modified retrospective basis. The impact of the adoption of this standard on December 29, 2018 was an increase in the beginning balance of the currency translation adjustment component of Accumulated other comprehensive loss of $1.0 million , and a decrease in Retained Earnings, as presented in the Company's Consolidated Balance Sheet. See Note 13 of the Consolidated Financial Statements for further details. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", with subsequent amendments, 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. The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)", with subsequent amendments, which requires changes to the accounting for leases and supersedes existing lease guidance, including ASC 840 - Leases. See Note 8 for further details.

Net Income Per Share	NET INCOME PER SHARE A reconciliation of the shares used in the computation of basic and diluted net income per share is as follows: Three Months Ended September 30, Nine Months Ended September 30, (SHARES IN THOUSANDS) 2019 2018 2019 2018 Net Income Net income attributable to IFF stockholders $ 127,124 $ 95,716 $ 372,330 $ 324,281 Add: Reduction in redemption value of redeemable noncontrolling interests in excess of earnings allocated 1,736 — 1,593 — Net income available to IFF stockholders $ 128,860 $ 95,716 $ 373,923 $ 324,281 Shares Weighted average common shares outstanding (basic) (1) 111,998 81,263 111,953 79,783 Adjustment for assumed dilution (2) : Stock options and restricted stock awards 332 267 372 293 SPC portion of TEUs 1,163 117 808 39 Weighted average shares assuming dilution (diluted) 113,493 81,647 113,133 80,115 Net Income per Share Net income per share - basic $ 1.15 $ 1.18 $ 3.34 $ 4.06 Net income per share - diluted 1.13 1.17 3.30 4.04 _______________________ (1) For the three and nine months ended September 30, 2019 , the tangible equity units (“TEUs”) were assumed to be outstanding at the minimum settlement amount for weighted-average shares for basic earnings per share. See below for details. (2) Effect of dilutive securities includes dilution under stock plans and incremental impact of TEUs. See below for details. The Company declared a quarterly dividend to its shareholders of $0.75 and $0.73 for the three months ended September 30, 2019 and 2018 , respectively. For the nine months ended September 30, 2019 and 2018 , the Company declared quarterly dividends to its shareholders totaling $2.21 and $2.11 , respectively. There were no stock options or stock-settled appreciation rights (“SSARs”) excluded from the computation of diluted net income per share for the three and nine months ended September 30, 2019 and 2018 . The Company issued 16,500,000 TEUs, consisting of a prepaid stock purchase contract ("SPC") and a senior amortizing note, for net proceeds of $800.2 million on September 17, 2018. For the periods outstanding, the SPC portion of the TEUs was assumed to be settled at the minimum settlement amount of 0.3134 shares per SPC for purposes of calculating weighted-average shares for the basic earnings per share calculation. For purposes of calculating diluted earnings per share, the SPCs were assumed to be settled at a conversion factor based on the 20 day volume-weighted average price (“VWAP”) per share of the Company’s common stock not to exceed 0.3839 shares per SPC. 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 September 30, 2019 and 2018 was immaterial. Net income allocated to such PRSUs was $0.2 million and $0.1 million for the three months ended September 30, 2019 and 2018 , respectively, and $0.5 million and $0.6 million for the nine months ended September 30, 2019 and 2018 , respectively.

Acquisitions

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS 2019 Acquisition Activity During the second quarter of 2019, the Company acquired the remaining 50% interest in an equity method investee located in Canada. The Company previously held an investment of $33 million in the entity and recognized a gain of approximately $3 million on the transaction within Other income, net in the Consolidated Statement of Income and Comprehensive (Loss) Income representing the adjustment of its historical investment to its fair value. The goodwill is not deductible for income tax purposes. The purchase of the additional interest increased the Company's ownership of the investee to 100% , and the acquired entity is managed under the Frutarom segment. The purchase price for the remaining 50% was approximately $37 million , including cash and an accrual for the amount expected to be paid in contingent consideration. The Company began to consolidate the results of the acquired entity from the date on which it acquired the remaining 50% interest during the second quarter of 2019. Goodwill of approximately $33 million and intangible assets of $24 million were recorded in connection with the acquisition. The purchase price allocation is preliminary and is expected to be completed within the measurement period. During the first quarter of 2019, the Company acquired 70% of a company in Europe and increased its ownership of an Asian company from 49% to 60% after receipt of previously pending regulatory approvals. The two acquired entities, which manufacture flavor products, are managed under the Frutarom segment. The total purchase price for the acquisitions was $52 million , excluding cash acquired and including $19 million of contingent consideration and deferred payments. The preliminary purchase price allocations have been performed and resulted in goodwill of approximately $56 million and intangible assets of $18 million . The purchase price allocations are preliminary and are expected to be completed within the measurement period. Pro forma information has not been presented as the entities acquired in 2019 are not material. Frutarom On October 4, 2018, the Company completed its acquisition of 100% of the equity of Frutarom Industries Ltd. (“Frutarom”). Purchase Price Allocation The Company allocated the purchase consideration to the tangible net assets and identifiable intangible assets acquired based on estimated fair values at the acquisition date, and recorded the excess of consideration over the fair values of net assets acquired as goodwill. The purchase price allocation was finalized as of the end of the third quarter of 2019. This involved finalizing the valuation of fixed assets, goodwill and intangible assets (trade names, product formulas, customer relationships and favorable/unfavorable leases and the related estimated useful lives). Additionally, this also involved finalizing the projected combined future tax rate applied to the valuation of assets, which impacted the valuation of goodwill and intangible assets. The following table summarizes the fair values of the assets acquired and liabilities assumed as of October 4, 2018, showing both the preliminary and final purchase price allocations: (IN THOUSANDS) As reported in the fourth quarter of 2018 Measurement period adjustments As reported in the third quarter of 2019 Cash and cash equivalents $ 140,747 $ 140,747 Other current assets 699,627 $ (25,706 ) 673,921 Identifiable intangible assets 2,690,000 (21,700 ) 2,668,300 Other non-current assets 353,710 58,401 412,111 Equity method investments 25,791 10,439 36,230 Current liabilities (311,325 ) (7,190 ) (318,515 ) Debt assumed (77,037 ) (77,037 ) Other liabilities (632,488 ) (39,730 ) (672,218 ) Redeemable noncontrolling interest (97,510 ) (5,392 ) (102,902 ) Noncontrolling interest (3,700 ) (3,700 ) Goodwill 4,243,079 30,878 4,273,957 Total Purchase Consideration $ 7,030,894 $ 7,030,894 The fair value purchase price allocation of the assets and liabilities acquired in the acquisition of Frutarom as reported in the fourth quarter of 2018 was updated during the nine months ended September 30, 2019 primarily due to: (i) a $19.0 million decrease in inventory, (ii) a $7.4 million decrease in trade receivables, (iii) a $21.7 million decrease in the fair value of identifiable intangible assets (principally customer relationships and product formulas and arising from the updated valuations of fixed assets), (iv) a $58.4 million increase primarily related to property, plant and equipment (related to certain entities), (v) a $10.4 million increase in the fair value of equity method investments, (vi) a $1.5 million increase to the noncurrent portion of earn-outs, (vii) a $14.4 million increase to deferred income tax liabilities, (viii) an $18.9 million increase to reserves for uncertain tax positions, (ix) a $5.0 million increase to environmental remediation liabilities, and (x) a $5.4 million increase to redeemable noncontrolling interest. The cumulative impact of the adjustments resulted in a $30.9 million increase to goodwill. The measurement period adjustments did not have a material impact on the Company's Net income attributable to IFF stockholders for the first, second, or third quarters of 2019. The components of acquired intangible assets with finite lives that have been recorded are as follows: (IN THOUSANDS) Estimated Amounts Estimated Useful Life Product formula $ 290,000 10 years Customer relationships 2,230,000 18 to 20 years Trade names 140,000 23 years Favorable/Unfavorable Leases, net 8,300 5 to 15 years Total $ 2,668,300 During the third quarter of 2019, in connection with the determination of the final purchase price allocation, the Company also finalized its determination of the reporting units for the Frutarom operating segment. The reporting units identified were as follows: (i) Taste; (ii) Savory Solutions; (iii) Inclusions; (iv) Fine Ingredients; and (v) Natural Product Solutions. In connection with the purchase price allocation, numerous assumptions were made including those related to future revenue growth, the achievement of synergy targets and the applicable rate to use in the discounted cash flows that form a key part of the valuation. The recoverability of the goodwill is principally dependent on future growth in revenues and from synergies related to plant and supply chain consolidation. The goodwill may be impaired if the Company fails to achieve the anticipated growth in revenues, the expected synergies or if applicable interest rates increase. Pro forma financial information The following unaudited pro forma financial information presents the combined results of operations of IFF and Frutarom as if the acquisition had been completed as of the beginning of the prior fiscal year, or January 1, 2018. The unaudited pro forma financial information is presented for informational purposes and is not indicative of the results of operations that would have been achieved if the acquisition and related borrowings had taken place on January 1, 2018, nor are they indicative of future results. The unaudited pro forma financial information for the three and nine months ended September 30, 2018 included the pre-acquisition results of Frutarom for that period. The unaudited pro forma results were as follows: (IN THOUSANDS) Three Months Ended September 30, 2018 Nine Months Ended September 30, 2018 Unaudited pro forma net sales $ 1,269,452 $ 3,906,506 Unaudited pro forma net income attributable to the Company 51,602 266,491 The unaudited pro forma results for all periods presented include adjustments made to account for certain costs and transactions that would have been incurred had the acquisition been completed as of January 1, 2018, including amortization charges for acquired intangibles assets, amortization of inventory step-up, adjustments for depreciation expense for property, plant, and equipment, and adjustments to interest expense. These adjustments are net of any applicable tax impact and were included to arrive at the pro forma results above.

Leases

Leases [Abstract]
Leases	LEASES During the quarter ended March 31, 2019, the Company adopted ASU No. 2016-02, “Leases (Topic 842),” which requires most leases to be recognized on the balance sheet. The Company adopted the standard using the modified retrospective approach with an effective date of December 29, 2018, the beginning of its 2019 fiscal year. Prior year financial statements were not recast. The Company elected various transition provisions available for expired or existing contracts, which allows the Company to carry forward historical assessments of (1) whether contracts are or contain leases, (2) lease classification and (3) initial direct costs. The Company leases property and equipment, principally under operating leases. In accordance with ASU 2016-02, the Company records a right-of-use asset and related obligation at the present value of lease payments and, over the term of the lease, depreciates the right-of-use asset and accretes the obligation to future value. Some of the leases include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. The Company does not separate lease and nonlease components of contracts. When available, the Company uses the rate implicit in the lease to discount lease payments to present value, however, most of the Company's leases do not provide a readily determinable implicit rate and the Company calculates the applicable incremental borrowing rate to discount the lease payments based on the term of the lease at lease commencement. The incremental borrowing rate is determined based on currency and lease terms. Certain leases contain variable payments which are periodically adjusted for changes in an index or rate. Such payments are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Subsequent changes in variable payments are not included in the lease liability, but are recognized in profit and loss during the period in which the obligation for those payments is incurred. The Company has operating leases for corporate offices, manufacturing facilities, research and development facilities, and certain transportation and office equipment, all of which are operating leases. The Company's leases have remaining lease terms of up to 40 years , some of which include options to extend the leases for up to 5 years . Upon adoption of the new guidance, the Company recorded a right-of-use asset of $308.3 million and total operating lease liabilities of $313.3 million . Additionally, the Company recorded a net increase to retained earnings of $23.1 million related to the elimination of deferred gains on certain sale-leaseback transactions that occurred in prior years.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Uncertain Tax Positions As of September 30, 2019 , the Company had $61.7 million of unrecognized tax benefits recorded in Other liabilities. The balance has been updated for $12.3 million associated with Frutarom uncertain tax positions recorded within the purchase accounting measurement period ending in the third quarter of 2019. If these unrecognized tax benefits were recognized, the effective tax rate would be affected. At September 30, 2019 , the Company had accrued interest and penalties of $11.2 million classified in Other liabilities. The balance has been updated for $6.6 million associated with Frutarom uncertain tax positions recorded within the purchase accounting measurement period ending in the third quarter of 2019. As of September 30, 2019 , the Company’s aggregate provisions for uncertain tax positions, including interest and penalties, was $72.9 million associated with tax positions asserted in various jurisdictions, none of which is individually material. The balance has been updated for $18.9 million associated with Frutarom uncertain tax positions recorded within the purchase accounting measurement period ending in the third quarter of 2019. The Company regularly repatriates earnings from non-U.S. subsidiaries. In the fourth quarter of 2018, the Company changed its assertion as part of its final analysis under SAB 118, consistent with the Company’s need to repatriate funds for debt repayment purposes. As the Company repatriates these funds to the U.S., they will be required to pay income taxes in certain U.S. states and applicable foreign withholding taxes during the period when such repatriation occurs. Accordingly, as of September 30, 2019 , the Company had a deferred tax liability of $43.9 million for the effect of repatriating the funds to the U.S. This balance consisted of $43.9 million attributable to IFF non-U.S. subsidiaries. We reversed the $43.7 million associated with Frutarom in the purchase accounting measurement period as we intend to indefinitely reinvest the earnings in the Frutarom 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 2009 to 2018. Based on currently available information, the Company does not believe the outcome of any of these tax audits and other tax positions related to open tax years, when finalized, will have a material impact on its results of operations. The Company also has other ongoing tax audits and legal proceedings that relate to indirect taxes, such as value-added taxes, sales and use taxes and property taxes, which are discussed in Note 15 . Effective Tax Rate The effective tax rate for the three months ended September 30, 2019 was 17.2% compared with 5.0% for the three months ended September 30, 2018 . The quarter-over-quarter increase was largely due to higher repatriation costs, the absence of the release of a state valuation allowance which benefited 2018 and an $8.0 million benefit recorded in the third quarter of 2018 to adjust the provisional “toll charge” associated with the transition to the new territorial tax system under U.S. tax reform, partially offset by a more favorable mix of earnings (including the impact of acquisition related costs). The effective tax rate for the nine months ended September 30, 2019 was 17.6% compared with 15.0% for the nine months ended September 30, 2018 . The year-over-year increase was largely due to higher repatriation costs, the absence of the remeasurement of loss provisions which benefited 2018 and an $8.0 million benefit recorded in the third quarter of 2018 to adjust the provisional “toll charge” associated with the transition to the new territorial tax system under U.S. tax reform, partially offset by a more favorable mix of earnings (including the impact of integration relates costs, restructuring charges and acquisition related costs).

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION The Company is currently organized into three reportable operating segments, Taste, Scent and Frutarom; these segments align with the internal structure used to manage these businesses. Taste is comprised of Flavor Compounds which are sold to the food and beverage industries for use in consumer products such as prepared foods, beverages, dairy, food and sweet products. Scent is comprised of (1) Fragrance Compounds, which are ultimately used by our customers in two broad categories: Fine Fragrances, including perfumes and colognes, and Consumer Fragrances, including fragrance compounds for personal care (e.g., soaps), household products (e.g., detergents and cleaning agents) and beauty care, including toiletries; (2) Fragrance Ingredients, consisting of synthetic and natural ingredients that can be combined with other materials to create unique fine fragrance and consumer compounds; and (3) Cosmetic Active Ingredients, consisting of active and functional ingredients, botanicals and delivery systems to support our customers’ cosmetic and personal care product lines. Major fragrance customers include the cosmetics industry, including perfume and toiletries manufacturers, and the household products industry, including manufacturers of soaps, detergents, fabric care, household cleaners and air fresheners. Frutarom creates and manufactures a naturals-focused suite of flavor compounds, functional foods and specialty fine ingredients, largely targeting small, local and regional customers. Frutarom’s products are focused on the following principal areas: Taste, Savory Solutions, Inclusions, Fine Ingredients, and Natural Product Solutions. The Company's Chief Operating Decision Maker evaluates the performance of these reportable operating segments based on segment profit which is defined as operating profit before restructuring, global expenses (as discussed below) and certain non-recurring items, Interest expense, Other income (expense), net and Taxes on income. The Global expenses caption represents corporate and headquarter-related expenses which include legal, finance, human resources, certain incentive compensation expenses and other R&D and administrative expenses that are not allocated to individual reportable operating segments.

Financial Instruments

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 3, other than those included in pension asset trusts as discussed in Note 16 of our 2018 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 September 30, 2019 . The carrying values and the estimated fair values of financial instruments at September 30, 2019 and December 31, 2018 consisted of the following: September 30, 2019 December 31, 2018 (DOLLARS IN THOUSANDS) Carrying Value Fair Value Carrying Value Fair Value LEVEL 1 Cash and cash equivalents (1) $ 494,897 $ 494,897 $ 634,897 $ 634,897 LEVEL 2 Credit facilities and bank overdrafts (2) 4,515 4,515 4,695 4,695 Derivatives Derivative assets — 11,555 — 7,229 Derivative liabilities — 1,149 — 6,907 Long-term debt: (3) 2020 Notes 299,167 303,360 298,499 300,356 2021 Euro Notes 325,993 331,248 337,704 341,094 2023 Notes 298,928 305,439 298,698 293,017 2024 Euro Notes 544,389 579,027 564,034 584,129 2026 Euro Notes 868,289 929,034 899,886 909,439 2028 Notes 396,611 442,000 396,377 401,231 2047 Notes 493,466 515,700 493,151 446,725 2048 Notes 785,943 907,008 785,788 783,925 Term Loan (2) 282,493 283,000 349,163 350,000 Amortizing Notes (4) 93,106 95,985 125,007 127,879 _______________________ (1) The carrying amount 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. (4) The fair value of the Amortizing Notes of the TEUs is based on the most recently quoted price for the outstanding securities, adjusted for any known significant deviation in value. The estimated fair value of these long-term obligations is not necessarily indicative of the amount that would be realized in a current market exchange. 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. In prior years, 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 change in the value of the cash flow hedges is recorded in OCI as a component of gains/(losses) on derivatives qualifying as hedges in the accompanying Consolidated Statement of Income and Comprehensive (Loss) 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 (Loss) Income in the same period as the related costs are recognized. In prior years, the Company designated the 2021 Euro Notes, 2024 Euro Notes and 2026 Euro Notes as a hedge of a portion of its net investment in Euro functional currency subsidiaries. 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 (Loss) Income . In prior years, 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 amount of gains and losses realized upon termination of these agreements is amortized over the life of the corresponding debt issuance. In prior years, the Company entered into certain cross currency swaps which qualified as net investment hedges in order to mitigate a portion of its net European investments from foreign currency risk. Changes in fair value related to cross currency swaps are recorded in OCI as a component of the Foreign currency translation adjustments. During the third quarter of 2019, the Company entered into a transaction to unwind the four cross currency swaps designated as net investment hedges issued in the fourth quarter of 2018 and received proceeds of $33.6 million , including interest income. The gain arising from the termination of the swaps has been included as a component of Accumulated other comprehensive loss . Following the termination of the existing swaps, the Company entered into four new EUR/USD cross currency swaps that mature through May 2023 covering the same notional amounts of debt. The new swaps qualified as net investment hedges in order to mitigate a portion of the Company's net European investments from foreign currency risk. As of September 30, 2019 , these swaps were in a net asset position with an aggregate fair value of $5.7 million which was classified as other current assets. Changes in fair value related to cross currency swaps are recorded in OCI. The following table shows the notional amount of the Company’s derivative instruments outstanding as of September 30, 2019 and December 31, 2018 : (DOLLARS IN THOUSANDS) September 30, 2019 December 31, 2018 Foreign currency contracts $ 411,436 $ 585,581 Cross currency swaps 600,000 600,000 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 September 30, 2019 and December 31, 2018 : September 30, 2019 (DOLLARS IN THOUSANDS) Fair Value of Fair Value of Total Fair Value Derivative assets (a) Foreign currency contracts $ 4,326 $ 1,501 $ 5,827 Cross currency swaps 5,728 — 5,728 $ 10,054 $ 1,501 $ 11,555 Derivative liabilities (b) Foreign currency contract $ 119 $ 1,030 $ 1,149 December 31, 2018 (DOLLARS IN THOUSANDS) Fair Value of Fair Value of Total Fair Value Derivative assets (a) Foreign currency contracts $ 4,122 $ 2,020 $ 6,142 Cross currency swaps 1,087 — 1,087 $ 5,209 $ 2,020 $ 7,229 Derivative liabilities (b) Foreign currency contracts $ 205 $ 6,702 $ 6,907 _______________________ (a) Derivative assets are recorded to Prepaid expenses and Other assets in the Consolidated Balance Sheet.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES 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 September 30, 2019 , the Company had total bank guarantees and standby letters of credit of $60.2 million with various financial institutions. Included in the above aggregate amount was a total of $17.0 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 September 30, 2019 . 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 $9.7 million as of September 30, 2019 . Lines of Credit The Company has various lines of credit which are available to support its ongoing business operations. As of September 30, 2019 , the Company had available lines of credit of $103.4 million with various financial institutions, in addition to the $948.0 million of capacity under the Amended Credit Facility. There were no material amounts drawn down pursuant to these lines of credit as of September 30, 2019 . 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. During the third quarter of 2019, in connection with the completion of the measurement period for finalizing the opening balance of Frutarom, the Company recorded an immaterial amount of reserves related to certain legal cases. The reserves were based on the determination that the loss was probable as of October 4, 2018 and updated as of September 30, 2019. The amount of future exposure is included in the estimate within the section "Other" below. Securities Class Action On August 12, 2019, Marc Jansen filed a putative securities class action against IFF, its Chairman and CEO, and its CFO, in the United States District Court for the Southern District of New York. The lawsuit, which was filed after IFF disclosed that preliminary results of investigations indicated that Frutarom businesses operating principally in Russia and Ukraine had made improper payments to representatives of customers, alleges that defendants made materially false and misleading statements or omissions concerning IFF’s acquisition of Frutarom, the integration of the two companies, and IFF’s financial reporting and results. The lawsuit brings claims under Section 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 against all defendants, and under Section 20(a) of the Securities Exchange Act of 1934 against the individual defendants, and was filed on behalf of a putative class of persons and entities who purchased or otherwise acquired IFF securities between May 7, 2018 and August 5, 2019. The complaint seeks an award of unspecified compensatory damages, costs, and expenses. On October 11, 2019, four lead plaintiff motions were filed. On October 24 and 25, 2019, two movants withdrew their motions for appointment as lead plaintiff. On October 25, 2019, the other two movants filed oppositions to the competing lead plaintiff motions. Two motions to approve securities class actions were filed in the Tel Aviv District Court, Israel in August 2019, similarly alleging, among other things, false and misleading statements largely in connection with IFF’s acquisition of Frutarom and the above-mentioned improper payments. Both assert claims under the U.S. federal securities laws against IFF, its Chairman and CEO, and its CFO. One also asserts claims under the Israeli Securities Act-1968 against IFF, as well as against Frutarom and certain former Frutarom officers and directors, and asserts claims under the Israeli Companies Act-1999 against certain former Frutarom officers and directors. On October 29, 2019, IFF and Frutarom filed a claim in the Tel Aviv District Court, Israel, against Ori Yehudai, the former President and CEO of Frutarom, and against certain former directors of Frutarom, challenging the bonus of US $20 million granted to Yehudai in 2018. IFF and Frutarom allege, among other things, that Yehudai was not entitled to receive the bonus because he breached his fiduciary duty by, among other things, knowing of the above-mentioned improper payments and failing to prevent them from being made. Environmental Over the past 20 years, various federal and state authorities and private parties have claimed that the Company is 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 seven 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 $3 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. During the third quarter of 2019, in connection with the completion of the measurement period for finalizing the opening balance of Frutarom, the Company recorded approximately $5 million in reserves related to certain environmental liabilities. The reserves were based on the determination that the loss was probable as of October 4, 2018 and updated as of September 30, 2019. The amount of future exposure is included the estimate within the section "Other" below. China Facilities Guangzhou Taste 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 Taste 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. To address the governmental authorities' requirements, the Company has begun to move production from the Guangzhou Taste plant to a newly built facility in Zhangjiagang. The net book value of the plant in Guangzhou was approximately $61 million as of September 30, 2019 . Guangzhou Scent plant During the second quarter of 2019, the Company was notified that certain governmental authorities had changed the zoning where the Guangzhou Scent plant is located. The zoning change did not affect the current operations but prevents expansions or other increases in the operating capacity of the plant. The Company believes that it is possible that the zoning may be enforced in the future such that it would not be able to continue manufacturing at the existing site. 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 $9 million as of September 30, 2019 . 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 2021. The Company received a payment of $15 million in both the fourth quarter of 2017 and the second quarter of 2019. The next payment of $15 million is expected in the first quarter of 2020. The net book value of the current plant was approximately $18 million as of September 30, 2019 . The Company relocated approximately half of the production capacity of the facility during the first half of 2019 and the remainder of the production capacity is expected to be relocated by the end of 2019. Total China Operations The total net book value of all eight plants in China was approximately $196 million as of September 30, 2019 . 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 $26.7 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. During 2018, the Company received an unfavorable ruling with respect to a claim related to potentially unpaid excise taxes from 1993. Based on the revised ruling, the Company has determined that it is now probable that it will have to pay the original claim in addition to penalties and interest. The total amount of the claim that has been recorded was $4.8 million . Ongoing Investigations IFF’s investigation of allegations that improper payments to representatives of customers were made in Russia and Ukraine has been substantiated, and IFF has confirmed that key members of Frutarom’s senior management at the time were aware of such payments. IFF has taken appropriate remedial actions, including replacing senior management in relevant locations, and believes that such improper customer payments have stopped. IFF has also confirmed that the estimated affected sales represented less than 1% of IFF’s and Frutarom’s combined net sales for 2018. The impact of the improper payments in Russia and Ukraine, including the costs resulting from the ensuing investigations, to date, have not been and are not anticipated to be material to IFF’s results of operations or financial condition. No evidence has been uncovered suggesting that any of these compliance matters had any connection to the United States 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 September 30, 2019 , the Company had recorded total charges of $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 in the first quarter of 2018 for a total of $16.0 million , of which $3.0 million was paid in the fourth quarter of 2017 and $13.0 million was paid during the three months ended March 31, 2018. The settlement of the claim did not have a material impact on the Company's financial condition. In the third quarter of 2018, the Company received $13.1 million for the full and final settlement of its claim from the supplier and insurer for the affected product. 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 $25 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.

Noncontrolling Interest [Abstract]
Redeemable Noncontrolling Interests	REDEEMABLE NONCONTROLLING INTERESTS Through certain subsidiaries of Frutarom, there are certain noncontrolling interests that carry redemption features. The noncontrolling interest holders have the right, over a stipulated period of time, to sell their respective interests to Frutarom, and Frutarom has the option to purchase these interests (subject to the same timing). These options carry identical price and conditions of exercise, and will be settled based on the multiple of the average EBITDA of consecutive quarters to be achieved during the period ending prior to the exercise date. The following table sets forth the details of the Company's redeemable noncontrolling interests: (DOLLARS IN THOUSANDS) Redeemable Noncontrolling Interests Balance at December 31, 2018 $ 81,806 Acquired through acquisitions during 2019 23,594 Impact of foreign exchange translation 923 Share of profit or loss attributable to redeemable noncontrolling interests 5,397 Redemption value adjustment for the current period (1,593 ) Measurement period adjustments 5,392 Dividends paid (432 ) Exercises of redeemable noncontrolling interests (542 ) Balance at September 30, 2019 $ 114,545 The increase in redeemable noncontrolling interests is primarily due to the interests acquired through acquisitions during the period, as discussed in Note 3.

Nature of Operations and Summary of Significant Accounting Policies (Policies)	9 Months Ended

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 2018 Annual Report on Form 10-K (“ 2018 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, September 30 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 2019 and 2018 quarters, the actual closing dates were September 27 and September 28 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	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“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.
Revenue Recognition	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 added, and other taxes the Company collects are excluded from revenues. The Company receives payment in accordance with standard customer terms.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In October 2018, the FASB issued Accounting Standards Update ("ASU") 2018-16, “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes." The ASU allows for the use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for purposes of applying hedge accounting under ASC 815, Derivatives and Hedging. The Company applied this new guidance as of December 29, 2018, the first day of the Company’s 2019 fiscal year. The adoption of the guidance did not have a material impact on the Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal - Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force).” The ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans (Subtopic 715-20)", which modifies the disclosure requirements on company-sponsored defined benefit plans. The ASU is effective for fiscal years beginning after December 15, 2020 on a retrospective basis to all periods presented. Early adoption is permitted. The Company has determined that this guidance will not have an impact on its Consolidated Financial Statements and will have a minimal impact on its disclosures. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820)", which modifies, removes and adds certain disclosure requirements on fair value measurements. The ASU is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. The Company has determined that this guidance will not have an impact on its Consolidated Financial Statements, as the Company has no applicable fair value measurements that are affected by the guidance. In June 2018, the FASB issued ASU 2018-07, "Compensation - Stock Compensation (Topic 718)" intended to reduce cost and complexity and to improve financial reporting for nonemployee share-based payments. This guidance expands the scope of Topic 718, Compensation-Stock Compensation which currently only includes share-based payments to employees to include share-based payments issued to nonemployees for goods or services. The Company applied this new guidance as of December 29, 2018, the first day of the Company’s 2019 fiscal year. The adoption of the guidance did not have a material impact on the Consolidated Financial Statements. In February 2018, FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" 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. The guidance was effective as of December 29, 2018, the first day of the Company's fiscal year. The Company elected to not reclassify any stranded tax effects to retained earnings. In August 2017, FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" 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, and as required, has been applied on a modified retrospective basis. The impact of the adoption of this standard on December 29, 2018 was an increase in the beginning balance of the currency translation adjustment component of Accumulated other comprehensive loss of $1.0 million , and a decrease in Retained Earnings, as presented in the Company's Consolidated Balance Sheet. See Note 13 of the Consolidated Financial Statements for further details. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", with subsequent amendments, 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. The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)", with subsequent amendments, which requires changes to the accounting for leases and supersedes existing lease guidance, including ASC 840 - Leases. See Note 8 for further details.
