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 2019 Annual Report on Form 10-K (“2019 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 2020 and 2019 quarters, the actual closing dates were October 2 and September 27, 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. The inputs into our judgments and estimates consider the current economic implications of the novel coronavirus ("COVID-19") on our critical and significant accounting estimates, including estimates associated with future cash flows that are used in assessing the risk of impairment of certain long lived assets. Actual results could differ from those estimates.

Cash, Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the Company's statement of cash flows periods ended September 30, 2020 and September 30, 2019 to the amounts reported in the Company's balance sheet as at September 30, 2020, December 31, 2019, September 30, 2019 and December 31, 2018.

Accounts Receivable

The Company has various factoring agreements in the U.S. and The Netherlands under which it can factor up to approximately $100 million in receivables. In addition, the Company has factoring agreements 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.

Through these factoring programs, the Company removed $209.3 million and $205.7 million of receivables from its balance sheets as of September 30, 2020 and December 31, 2019, respectively, which are primarily related to the factoring agreements sponsored by certain customers.

The impact on cash provided by operations from participating in these programs was an increase of $3.6 million for the nine months ended September 30, 2020 and an increase of $36.8 million for the nine months ended September 30, 2019.

The cost of participating in these programs was $1.1 million and $1.7 million for the three months ended September 30, 2020 and 2019, respectively, and was $3.1 million and $4.7 million for the nine months ended September 30, 2020 and 2019, respectively.

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.

The following table presents the Company's revenues disaggregated by product categories:

Total revenues	$	1,268,076	$	1,267,345	$	3,814,166	$	3,856,315

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 following table reflects the balances in the Company's accounts receivable, contract assets, and contract liabilities for the periods ended September 30, 2020 and December 31, 2019:


(DOLLARS IN THOUSANDS)	September 30, 2020		December 31, 2019

Recent Accounting Pronouncements

In March 2020, the FASB issued Accounting Standards Update ("ASU") 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The ASU is intended to simplify various aspects related to the cessation of reference rates in certain financial markets that would otherwise create modification accounting or changes in estimate. This guidance is effective for the period from March 12, 2020 to December 31, 2022. The Company has not adopted any of the optional expedients or exceptions through September 30, 2020 but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” The ASU is intended to simplify various aspects related to accounting for income taxes. This guidance is effective for fiscal years beginning after December 15, 2020, and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact this guidance may have on its 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 adopted the guidance effective the first day of its 2020 fiscal year. The adoption did not have an impact on its consolidated financial statements but may impact the Company in the future as and when it enters into cloud computing arrangements.

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 adopted the guidance effective the first day of its 2020 fiscal year. The adoption did not have an impact on its Consolidated Financial Statements and will have a minimal impact on its disclosures in future periods.

Adoption of Standard Related to Expected Credit Losses

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, which may result in earlier recognition of losses.

The Company adopted the guidance effective the first day of its 2020 fiscal year and performed an evaluation of the applicable criteria, including the aging of its trade receivables, recent write-off history and other factors related to future macroeconomic conditions. As a result of the evaluation, the Company determined that no adjustment would be required to the level of its allowances for bad debts or to the carrying value of any other financial asset.

The Company is exposed to credit losses primarily through its sales of products. To determine the appropriate allowance for expected credit losses, the Company considers certain credit quality indicators, such as aging, collection history, and creditworthiness of debtors. Regional and Global Credit committees review and approve specific customer allowance reserves. The allowance for expected credit losses is primarily based on two primary factors: i) the aging of the different categories of trade receivables, and ii) a specific reserve for accounts identified as uncollectable.

The Company also considers current and future economic conditions in the determination of the allowance. At September 30, 2020, the Company reported $928.6 million of trade receivables, net of allowances of $22.5 million. Based on the aging analysis as of September 30, 2020, approximately 87% of our accounts receivable were current based on the payment terms of the invoice. Receivables that are past due by over 365 days account for approximately 1% of our accounts receivable.

The following is a rollforward of the Company's allowances for bad debts for the nine months ended September 30, 2020:


(DOLLARS IN THOUSANDS)	Allowances for Bad Debts
Balance at December 31, 2019	$	16,428
Bad debt expense	7,443
Write-offs	(587)
Foreign exchange	(771)
Balance at September 30, 2020	$	22,513

The Company adjusted the amount of the allowances for bad debts as of December 31, 2019 to reflect the correct classification of amounts between the allowances for bad debts and Trade Receivables. The adjustment was for $8.2 million and had the effect of increasing both the allowances for bad debts and Trade Receivables.

During the first quarter of 2020, the Company increased its allowances for bad debts by approximately $3.0 million to reflect higher expected future write-offs of receivables due to the impact of the COVID-19 pandemic and its impact on the liquidity of certain customers. The Company has not made any additional increases to its allowances for bad debts, as a result of COVID-19, in the second and third quarters of 2020.

On January 17, 2020, N&B entered into a term loan credit agreement, as amended on August 25, 2020, providing for unsecured term loan facilities in an aggregate principal amount of $1.25 billion, which reduced the commitments under the Bridge Loans commitment letter by a corresponding amount. On September 16, 2020, N&B issued $6.25 billion of senior unsecured notes, which reduced the remaining commitments under the Bridge Loans commitment letter in their entirety. The Bridge Loans commitment letter was also terminated as of such date. The N&B Notes, together with the Term Loan Facilities, will be used to finance the Special Cash Payment and to pay related fees and expenses. Following the consummation of the merger, all obligations of N&B with respect to the Term Loan Facilities and the N&B Notes will be guaranteed by IFF (or at the election of N&B and IFF, assumed by IFF). Lines of Credit The Company has various lines of credit which are available to support its ongoing business operations. As of September 30, 2020, the Company had available lines of credit of $107.2 million with various financial institutions, in addition to the $627.7 million of capacity under the Credit Facility. There were no material amounts drawn down pursuant to these lines of credit as of September 30, 2020. Litigation The Company assesses contingencies related to litigation and/or other matters to determine the degree of probability and range of possible loss. A loss contingency is accrued in the Company’s consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly sensitive and requires judgments about future events. On at least a quarterly basis, the Company reviews contingencies related to litigation to determine the adequacy of accruals. The amount of ultimate loss may differ from these estimates and further events may require the Company to increase or decrease the amounts it has accrued on any matter. Periodically, the Company assesses its insurance coverage for all known claims, where applicable, taking into account aggregate coverage by occurrence, limits of coverage, self-insured retentions and deductibles, historical claims experience and claims experience with its insurance carriers. The liabilities are recorded at management’s best estimate of the probable outcome of the lawsuits and claims, taking into consideration the facts and circumstances of the individual matters as well as past experience on similar matters. At each balance sheet date, the key issues that management assesses are whether it is probable that a loss as to asserted or unasserted claims has been incurred and if so, whether the amount of loss can be reasonably estimated. The Company records the expected liability with respect to claims in Other liabilities and expected recoveries from its insurance carriers in Other assets. The Company recognizes a receivable when it believes that realization of the insurance receivable is probable under the terms of the insurance policies and its payment experience to date. Litigation Matters On August 12, 2019, Marc Jansen filed a putative securities class action against IFF, its Chairman and CEO, and its then-CFO, in the United States District Court for the Southern District of New York. The lawsuit 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. On December 26, 2019, the Court appointed a group of six investment funds as lead plaintiff and Pomerantz LLP as lead counsel. On March 16, 2020, lead plaintiff filed an amended complaint, which added Frutarom and certain former officers of Frutarom as defendants. The amended complaint alleges, among other things, that defendants made materially false and misleading statements or omissions concerning IFF’s acquisition of Frutarom, the integration of the two companies, and the companies’ financial reporting and results. The amended complaint asserts claims under Section 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5, and under the Israeli Securities Act-1968, against all defendants, and under Section 20(a) of the Securities Exchange Act of 1934 against the individual defendants, on behalf of a putative class of persons and entities who purchased or otherwise acquired IFF securities on the New York Stock Exchange between May 7, 2018 and August 12, 2019 and persons and entities who purchased or otherwise acquired IFF securities on the Tel Aviv Stock Exchange between October 9, 2018 and August 12, 2019. The amended complaint seeks an award of unspecified compensatory damages, costs, and expenses. IFF filed a motion to dismiss the case on June 26, 2020. 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. One motion asserts claims under the U.S. federal securities laws against IFF, its Chairman and CEO, and its former CFO. The other ("Oman") (following an amendment) asserts claims under the Israeli Securities Act-1968 against IFF, its Chairman and CEO, and its former CFO, and against Frutarom and certain former Frutarom officers and directors, as well as claims under the Israeli Companies Act-1999 against certain former Frutarom officers and directors. On October 4, 2020, the Oman plaintiff filed a motion to remove IFF and its officers from the motion and to add factual allegations from the US amended complaint. 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. The parties agreed, pursuant to the court’s recommendation, to attempt to resolve the dispute through mediation, which is scheduled for the fourth quarter 2020, during which the proceedings relating to this claim are stayed. On March 11, 2020, an IFF shareholder filed a motion to approve a class action in Israel against, among others, Frutarom, Yehudai, and Frutarom’s former board of directors, alleging that former minority shareholders of Frutarom were harmed as a result of the US $20 million bonus paid to Yehudai. The parties to this motion agreed to attempt to resolve the dispute through mediation to take place regarding the aforesaid claim against Yehudai, during which the proceedings relating to this motion are stayed. Investigation On June 3, 2020, the Israel Police’s National Fraud Investigation Unit and the Israeli Securities Authority commenced an investigation into Frutarom and certain of its former executives, based on suspected bribery of foreign officials, money laundering, and violations of the Israeli Securities Act-1968. The National Fraud Investigation Unit and the Israeli Securities Authority have provided IFF and Frutarom with various orders. IFF is working to ensure compliance with such orders, all in accordance with, and subject to, Israeli law. 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 transfer certain production capabilities from the Guangzhou Taste plant to a newly built facility in Zhangjiagang. The net book value of the plant in Guangzhou was approximately $60 million as of September 30, 2020. 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, 2020. 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 2022. The Company received payments totaling $30 million through the end of 2019. In the third quarter of 2020, the Company received a payment of approximately $13 million. A final payment is expected to be received upon completion of the final environmental inspection. Production at the facility ceased during 2019. In the second quarter of 2020, the Company transferred ownership of the site to the government. The land remediation activities are in progress and are expected to be completed in the second half of 2022. During the second quarter of 2020, the remaining net book value of the plant was written off. Total China Operations The total net book value of all seven plants in China was approximately $199 million as of September 30, 2020. 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 $20.7 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. Pending Transaction with Nutrition & Biosciences, Inc. The Merger Agreement governing the DuPont N&B Transaction, subjects IFF to various contingent payments to the extent that the transaction is not consummated. Specifically, the Merger Agreement provides DuPont the right to receive a termination fee of $521.5 million, in certain circumstances, including if the agreement is terminated due to the IFF Board changing its recommendation. In addition, if the Merger Agreement is terminated, DuPont and IFF have agreed to split 50/50 any commitment fees incurred in connection with the debt financing for the DuPont N&B Transaction. On August 27, 2020, a special shareholder meeting was held and IFF shareholders voted to approve the issuance of shares of IFF Common Stock in connection with the DuPont N&B Transaction pursuant to the Merger Agreement. Brazil Tax Credits In January 2020, the Company was informed of a favorable ruling from the Brazilian tax authorities confirming that the Company was entitled to recover the overpayments of certain indirect taxes (known as PIS/COFINS) for the period from November 2011 to December 2018, plus interest on the amount of the overpayments. The overpayments arose from the inclusion of a value added tax known as ICMS in the calculation of the PIS/COFINS tax. The ruling did not, however, settle the question of whether the Company is eligible to recover overpayments based on the gross or the net amount of ICMS amounts paid on PIS/COFINS. The Company calculated the amount of overpayments using the gross method which yields a higher amount than the application of the net method. A final ruling on the gross versus net amount issued is still pending. In addition to the $8.0 million recognized in the fourth quarter of 2019, during the first quarter of 2020 the Company recognized $3.5 million as an additional recovery on the existing claim. During the first nine months of 2020, the Company also recognized $2.7 million related to a claim from another of its subsidiaries in Brazil. The income is recognized as a reduction in Selling and Administrative expenses. 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 $0.1 million to approximately $12.0 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.

2022 Term Loan

On May 15, 2020, the Company entered into a Term Loan Agreement (the "2022 Term Loan Agreement") with China Construction Bank Corporation, New York Branch, as administrative agent, and the lenders party thereto.

The lenders party to the 2022 Term Loan Agreement have committed to provide a senior unsecured two year term loan facility in an aggregate principal amount of up to $200 million. The loans under the 2022 Term Loan Agreement bear interest, at the Company's option, at a per annum rate equal to either (x) an adjusted LIBOR rate plus an applicable margin varying from 1.225% to 2.475% or (y) a base rate plus an applicable margin varying from 0.225% to 1.475%, in each case depending on the public debt ratings for non-credit enhanced long-term senior unsecured debt issued by the Company. The Company may voluntarily prepay the term loans without premium or penalty, with the balance payable on the second anniversary of the funding date. There is no required amortization under the 2022 Term Loan Agreement.

As of September 30, 2020, the Company had $200 million outstanding in borrowings under the 2022 Term Loan Agreement. The 2022 Term Loan Agreement contains various covenants, limitations and events of default customary for similar facilities for similarly rated borrowers, including a maximum ratio of net debt to EBITDA of 4.0x with step-downs over time.

2020 Notes

During the third quarter of 2020, the Company repaid the 2020 Notes resulting in a payment of $300 million of which approximately $200 million was from the net proceeds received under the 2022 Term Loan Agreement.

Amended Debt Agreements

On August 25, 2020, the Company entered into (i) the Second Amended and Restated Revolving Credit Agreement (the "Revolving Credit Agreement"), which amended and restated the Credit Agreement dated as of November 9, 2011, as previously amended and restated as of December 2, 2016, and further amended as of May 21, 2018, June 6, 2018, July 13, 2018 and January 17, 2020 among the Company, certain of its subsidiaries, the lenders party thereto and Citibank, N.A. as administrative agent, (ii) an amendment to the Term Loan Credit Agreement, dated as of June 6, 2018, as previously amended as of July 13, 2018 and as of January 17, 2020, among the Company, the lenders party thereto, and Morgan Stanley Senior Funding, Inc. as administrative agent (as amended, the "Frutarom Term Loan Agreement") and (iii) an amendment to the 2022 Term Loan Agreement (as amended, and collectively with the Revolving Credit Agreement and Frutarom Term Loan Agreement, the "Amended Debt Agreements").

Under the amended terms of the Revolver Credit Agreement, the senior unsecured revolving loan credit facility maturing June 6, 2023 (the "Revolving Credit Facility") will increase from $1 billion to $2 billion upon completion of the DuPont N&B Transaction.

Additionally, under the Amended Debt Agreements, upon the completion of the DuPont N&B Transaction, the Company's maximum permitted ratio of net debt to Consolidated EBITDA will increase to 4.75x with step-downs over time.

Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

During the first quarter of 2020, the Company reorganized its reporting structure and combined substantially all of the components of the former Frutarom reportable operating segment into the former Taste reportable operating segment. Prior year amounts have been recast to conform to the current year reporting structure. As a result of the reorganization, the Company is now organized into two reportable operating segments, Taste and Scent; these segments align with the internal structure used to manage these businesses.

Taste is comprised of a diversified portfolio across flavor compounds, savory solutions, inclusions and nutrition and specialty ingredients. Flavor compounds provide unique flavors that are ultimately used by IFF's customers in savory products, beverages, sweets, and dairy products. Savory solutions include marinades or powder blends of flavors, natural colors, seasonings, functional ingredients and natural anti-oxidants that are primarily designed for the meat and fish industry. Inclusions provide taste and texture by, among other things, combining flavorings with fruit, vegetables, and other natural ingredients for a wide range of food products, such as health snacks, baked goods, cereals, pastries, ice cream and other dairy products. Nutrition and specialty ingredients primarily consist of natural health ingredients, natural food protection, natural colors and flavor ingredients. The flavor ingredients market includes natural flavor extracts, specialty botanical extracts, distillates, essential oils, citrus products, aroma chemicals, and natural gums and resins. Such ingredients are used for food, beverage, and flavors and are often sold directly to food and beverage manufacturers who use them in producing consumer 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.

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.

Reportable segment information was as follows:

Noncontrolling Interest [Abstract]

Redeemable Noncontrolling Interests

REDEEMABLE NONCONTROLLING INTERESTSThrough certain subsidiaries of our Frutarom acquisition, 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:

For 2019, the increase in redeemable noncontrolling interests was primarily due to the interests acquired through acquisitions during the first quarter of 2019, as discussed in Note 3.

During 2020, the Company paid $13.1 million related to the purchase of certain noncontrolling interests where the option related to the purchase had been exercised in the fourth quarter of 2019.

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 2019 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, 2020.

The carrying values and the estimated fair values of financial instruments at September 30, 2020 and December 31, 2019 consisted of the following:

_______________________

(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 carrying amount approximates fair value as the instruments are marked-to-market and held at fair value on the Consolidated Balance Sheet.

(4)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

Foreign Currency Forward Contracts

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.

Cash Flow Hedges

The Company maintains 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 (Losses) gains on derivatives qualifying as hedges in the accompanying Consolidated Statement of Income and Comprehensive Income (Loss). 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 (Loss) in the same period as the related costs are recognized.

Hedges Related to Issuances of Debt

Subsequent to the issuance of the 2021 Euro Notes and 2026 Euro Notes during the third quarter of 2018, 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 (Loss).

Subsequent to the issuance of the 2024 Euro Notes 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 (Loss).

Cross Currency Swaps

During the third quarter of 2019, the Company entered into four EUR/USD cross currency swaps that mature through May 2023. The swaps all qualified as net investment hedges in order to mitigate a portion of the Company's net European investments from foreign currency risk. During the third quarter of 2020, the Company entered into a transaction to unwind two of the swaps issued in the third quarter of 2019 and paid proceeds of $14.6 million, net of accrued interest receivable of $2.2 million. The loss arising from the termination of the swaps has been included as a component of accumulated other comprehensive loss. As of September 30, 2020, the two remaining swaps were in a net liability position with an aggregate fair value of $8.5 million which was classified as other current liabilities. 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, 2020 and December 31, 2019:

(1)Interest rate swaps were entered into as pre-issuance hedges for bond offerings.

The ineffective portion of the above noted cash flow hedges were not material during the three and nine months ended September 30, 2019.

The Company expects that $4.1 million (net of tax) of derivative gain included in AOCI at September 30, 2020, 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.

(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 $0.77 and $0.75 per share for the three months ended September 30, 2020 and 2019, respectively. For the nine months ended September 30, 2020 and 2019, the Company declared quarterly dividends to its shareholders totaling $2.27 and $2.21 per share, 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, 2020 and 2019.

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 purposes of calculating basic net income per share, the SPCs were assumed to be settled at the minimum settlement amount of 0.3134 shares per SPC on September 30, 2020 and 2019. For purposes of calculating diluted earnings per share, the SPCs were assumed to be settled at a conversion factor not to exceed 0.3839 on September 30, 2020 and 2019. The SPC conversion factor is based on the 20 day volume-weighted average price (“VWAP”) per share of the Company’s common stock. Per the TEU agreement, the maximum settlement amount is 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.

Acquisitions	Sep. 30, 2020
Business Combinations [Abstract]
Acquisitions	ACQUISITIONS Pending Transaction with Nutrition & Biosciences, Inc. On December 15, 2019, the Company entered into definitive agreements with DuPont de Nemours, Inc. (“DuPont”), including an Agreement and Plan of Merger (the "Merger Agreement"), pursuant to which DuPont will transfer its nutrition and biosciences business to Nutrition & Biosciences, Inc., a Delaware corporation and wholly owned subsidiary of DuPont (“N&B”), and N&B will merge with and into a wholly owned subsidiary of IFF in exchange for a number of shares of IFF common stock, par value $0.125 per share (“IFF Common Stock”) (collectively, the “DuPont N&B Transaction”). In connection with the transaction, DuPont will receive a one-time $7.3 billion special cash payment (the “Special Cash Payment”), subject to certain adjustments. As a result of the DuPont N&B Transaction, holders of DuPont’s common stock will own approximately 55.4% of the outstanding shares of IFF on a fully diluted basis. Completion of the DuPont N&B Transaction is subject to various closing conditions, including, among other things, (1) approval by IFF’s shareholders of the issuance of IFF Common Stock in connection with the transaction (which approval has been obtained); (2) the effectiveness of the registration statements to be filed with the Securities and Exchange Commission pursuant to the Merger Agreement; and (3) the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (which waiting period has expired), and obtaining certain other consents, authorizations, orders or approvals from governmental authorities. We expect that the transaction will close in early 2021. On December 15, 2019, IFF and N&B entered into a commitment letter which provides $7.5 billion in an aggregate principal amount of senior unsecured bridge term loans (the "Bridge Loans"). On January 17, 2020, N&B entered into a term loan credit agreement, as amended on August 25. 2020, providing for unsecured term loan facilities in an aggregate principal amount of $1.25 billion (the “Term Loan Facilities”), which reduced the commitments under the Bridge Loans commitment letter by a corresponding amount. On September 16, 2020, N&B issued $6.25 billion of senior unsecured notes (the “N&B Notes”), which reduced the remaining commitments under the Bridge Loans commitment letter in their entirety. The Bridge Loans commitment letter was also terminated as of such date. The N&B Notes, together with the Term Loan Facilities, will be used to finance the Special Cash Payment and to pay related fees and expenses. Following the consummation of the merger, all obligations of N&B with respect to the Term Loan Facilities and the N&B Notes will be guaranteed by IFF (or at the election of N&B and IFF, assumed by IFF). On August 27, 2020, a special shareholder meeting was held and IFF shareholders voted to approve the issuance of shares of IFF Common Stock in connection with the DuPont N&B Transaction pursuant to the Merger Agreement. 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 purchase of the additional interest increased the Company's ownership of the investee to 100%. 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 $30 million and intangible assets of $20 million were recorded in connection with the acquisition. 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%. The total purchase price for the two acquisitions made in the first quarter of 2019 was $52 million, excluding cash acquired and including $19 million of contingent consideration and deferred payments. The purchase price allocations have been performed and resulted in goodwill of approximately $47 million and intangible assets of $28 million. During the first quarter of 2020, the Company completed the purchase price allocations for all three of the transactions that were made during 2019. As a result of finalizing the purchase price allocations, adjustments were recorded to increase fixed assets by $13 million, customer relationships and other intangible assets by $5 million and approximately $3 million related to deferred tax liabilities and to decrease goodwill by $15 million. The income statement impact of the finalization of purchase accounting was not material. Pro forma information has not been presented as the entities acquired in 2019 were not material.

Potential COVID-19 Impact

Although IFF does not currently anticipate any impairment charges related to COVID-19, the continuing effects of a prolonged pandemic could result in increased risk of asset write-downs and impairments to goodwill and intangibles.
