CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

Some of the statements and information in this Quarterly Report on Form 10-Q contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We may also make written or oral forward-looking statements in our reports on Forms 10-K, 10-Q, and 8-K, in press releases and other written materials and in oral statements made by our officers, directors, or employees to third parties. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Forward-looking statements are often characterized by the use of words such as “outlook,” “believes,” “estimates,” “expects,” “projects,” “may,” “intends,” “plans,” “anticipates,” “forsees,” “future,” or by discussions of strategy, plans, or intentions; anticipated benefits of or performance of our products; beliefs regarding opportunities for new, differentiated applications, and other innovations; beliefs regarding strengthening relationships with customers; adequacy of cash flows to fund our working capital requirements; our investment in the joint venture with Formosa Petrochemical Corporation (“FPCC”); our expectations regarding indebtedness to be incurred by our joint venture with FPCC; debt payments, interest payments, benefit plan contributions, and income tax obligations; nonrealization of expected benefits from our acquisitions or business dispositions and our ability to timely execute and close such acquisitions and dispositions; our anticipated capital expenditures, health, safety, environmental, and security and infrastructure and maintenance projects, projects to optimize the production capabilities of our manufacturing assets and to support our innovation platform; our ability to fully access our senior secured credit facilities; expectations regarding future dividend payments; expectations regarding our counterparties’ ability to perform, including with respect to trade receivables; estimates regarding tax expense of repatriating certain cash and short-term investments related to foreign operations; expectations regarding differentiated applications; our ability to realize certain deferred tax assets and our beliefs with respect to tax positions; expectations regarding our full year effective tax rate; estimates related to the useful lives of certain assets for tax purposes; expectations regarding our pension contributions; estimates or expectations related to raw material costs or availability, ending inventory levels and related estimated charges; the outcome and financial impact of legal proceedings; expectations regarding the spread between FIFO and ECRC (each as defined herein) in future periods; expectations regarding the impact of natural disasters and replacement costs resulting therefrom; estimated impacts of changing tariff rates and logistics costs; the estimates and matters described in our latest Annual Report on Form 10-K and in subsequent Quarterly Reports on Form 10-Q under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments and Known Trends;” and projections regarding environmental costs and capital expenditures and related operational savings.

Forward-looking statements involve known and unknown risks, uncertainties, assumptions, and other important factors that could cause the actual results, performance or our achievements, or industry results, to differ materially from historical results, any future results, or performance or achievements expressed or implied by such forward-looking statements. There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in this report. Important factors that could cause our actual results to differ materially from those expressed as forward-looking statements include, but are not limited to the factors set forth in this report, in our latest Annual Report on Form 10-K, including but not limited to “Part I, Item 1A. Risk Factors” and “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” therein, and in our other filings with the Securities and Exchange Commission (the “SEC”).

There may be other factors of which we are currently unaware or deem immaterial that may cause our actual results to differ materially from the forward-looking statements. In addition, to the extent any inconsistency or conflict exists between the information included in this report and the information included in our prior reports and other filings with the SEC, the information contained in this report updates and supersedes such information.

Forward-looking statements are based on current plans, estimates, assumptions and projections, and, therefore, you should not place undue reliance on them. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update them in light of new information or future events.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Kraton Corporation:

Results of Review of Interim Financial Information

We have reviewed the condensed consolidated balance sheet of Kraton Corporation and subsidiaries (the Company) as of June 30, 2019, the related condensed consolidated statements of operations and comprehensive income (loss) for the three and six-month periods ended June 30, 2019 and 2018, the related condensed consolidated statements of changes in equity and cash flows for the six-month periods ended June 30, 2019 and 2018, and the related notes (collectively, the consolidated interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial information for it to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2018, and the related consolidated statements of operations, comprehensive income (loss), changes in equity, and cash flows for the year then ended (not presented herein); and in our report dated February 28, 2019, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2018, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This consolidated interim financial information is the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with the standards of the PCAOB. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

1. General

Description of our Business. We are a leading global specialty chemicals company that manufactures styrenic block copolymers (“SBCs”), specialty polymers, and high-value performance products primarily derived from pine wood pulping co-products.

SBCs are highly-engineered synthetic elastomers, which we originally invented and commercialized. Our SBCs enhance the performance of numerous products by imparting greater flexibility, resilience, strength, durability, and processability, and are used in a wide range of applications, including adhesives, coatings, consumer and personal care products, sealants, lubricants, medical, packaging, automotive, and paving and roofing products. We manufacture and sell isoprene rubber and isoprene rubber latex, which are non-SBC products primarily used in applications such as medical products, personal care, adhesives, tackifiers, paints, and coatings.

We refine and further upgrade crude tall oil and crude sulfate turpentine, into value-added specialty chemicals. These pine-based specialty products are sold into adhesive and tire markets, and we produce and sell a broad range of performance chemicals (which we formerly referred to as chemical intermediates) into markets that include fuel additives, oilfield chemicals, coatings, metalworking fluids and lubricants, inks, flavors and fragrances, and mining.

Basis of Presentation. The accompanying unaudited Condensed Consolidated Financial Statements presented in this report are for us and our consolidated subsidiaries, each of which is a wholly-owned subsidiary, except our 50% investment in our joint venture, Kraton Formosa Polymers Corporation (“KFPC”), located in Mailiao, Taiwan. KFPC is a variable interest entity for which we have determined that we are the primary beneficiary and, therefore, have consolidated into our financial statements. Our 50% investment in our joint venture located in Kashima, Japan, is accounted for under the equity method of accounting. All significant intercompany transactions have been eliminated. These interim financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly our results of operations and financial position. Amounts reported in our Condensed Consolidated Statements of Operations are not necessarily indicative of amounts expected for the respective annual periods or any other interim period, in particular due to the effect of seasonal changes and weather conditions that typically affect our sales into paving, roadmarking, roofing, and construction applications. In particular, sales volumes into these applications are generally higher in the second and third quarter of the calendar year as warm and dry weather is more conducive to paving and roofing activity.

Reclassifications. Certain amounts reported in the condensed consolidated financial statements and notes to the consolidated financial statements for the prior periods have been reclassified to conform to the current reporting presentation.

Significant Accounting Policies. Our significant accounting policies have been disclosed in Note 1 Description of Business, Basis of Presentation, and Significant Accounting Policies in our most recent Annual Report on Form 10-K. Except for the changes below, the Company has consistently applied the accounting policies presented in the Condensed Consolidated Financial Statements.

Leases. See Note 2 New Accounting Pronouncements, for the impact of ASC 842, Leases, adopted in the current period.

There have been no other changes to the accounting policies, which are disclosed in our most recent Annual Report on Form 10-K. The accompanying unaudited Condensed Consolidated Financial Statements we present in this report have been prepared in accordance with our policies.

Use of Estimates. The preparation of these Condensed Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant items subject to such estimates and assumptions include:

• the useful lives of long-lived assets;

• estimates of fair value for assets acquired and liabilities assumed in business combinations;

• allowances for doubtful accounts and sales returns;

• the valuation of derivatives, deferred tax assets, property, plant and equipment, intangible assets, inventory, investments, and share-based compensation; and

• liabilities for employee benefit obligations, environmental matters, asset retirement obligations, income tax uncertainties, and other contingencies.

11

Income Tax in Interim Periods. We conduct operations in separate legal entities in different jurisdictions. As a result, income tax amounts are reflected in these Condensed Consolidated Financial Statements for each of those jurisdictions. Tax laws and tax rates vary substantially in these jurisdictions and are subject to change based on the political and economic climate in those countries. We file our tax returns in accordance with our interpretations of each jurisdiction’s tax laws. We record our tax provision or benefit on an interim basis using the estimated annual effective tax rate. This rate is applied to the current period ordinary income or loss to determine the income tax provision or benefit allocated to the interim period.

Losses from jurisdictions for which no benefit can be realized and the income tax effects of unusual and infrequent items are excluded from the estimated annual effective tax rate. Valuation allowances are provided against the future tax benefits that arise from the losses in jurisdictions for which there is uncertainty that they may be realized. The effects of unusual and infrequent items are recognized in the impacted interim period as discrete items.

The estimated annual effective tax rate may be significantly affected by nondeductible expenses and by our projected earnings mix by tax jurisdiction. Adjustments to the estimated annual effective income tax rate are recognized in the period during which such estimates are revised.

We have established valuation allowances against a variety of deferred tax assets, including net operating loss carryforwards, foreign tax credits and other income tax credits. Valuation allowances take into consideration our expected ability to realize these deferred tax assets and reduce the value of such assets to the amount that is deemed more likely than not to be recoverable. Our ability to realize these deferred tax assets is dependent on achieving our forecast of future taxable operating income over an extended period of time. We review our forecast in relation to actual results and expected trends on a quarterly basis. If we fail to achieve our operating income targets, we may change our assessment regarding the recoverability of our net deferred tax assets and such change could result in a valuation allowance being recorded against some or all of our net deferred tax assets. A change in our valuation allowance would impact our income tax benefit (expense) and our stockholders’ equity and could have a significant impact on our results of operations or financial condition in future periods.

2. New Accounting Pronouncements

Accounting Standards Adopted in the Current Period

We have implemented all new accounting pronouncements that are in effect and that management believes would materially affect our financial statements.

In February 2016, the FASB established Topic 842, Leases, by issuing ASU 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; and ASU 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (“ROU”) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application. The new standard provides a number of optional practical expedients in transition. We elected the following practical expedients: (1) ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification, and initial direct costs; (2) the short-term lease recognition exemption for all leases that qualify; and (3) the practical expedient to not separate lease and non-lease components for all of our leases.

This standard had a material effect on our financial statements. The most significant effects relate to: (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our equipment, building, and vehicle operating leases; (2) the derecognition of existing assets and liabilities for straight line lease accounting under ASC 840 Leases; and (3) providing significant new disclosures about our leasing activities. On adoption, we recognized additional operating liabilities of $70.9 million, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objective of this ASU is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This standard is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2017-12 was completed during 2018 and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2017-12 effective January 1, 2019.

12

In October 2018, the FASB issued 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. This standard is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2018-16 was completed during 2018, and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2018-16 effective January 1, 2019.

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2018-02 was completed during 2018, and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2018-02 effective January 1, 2019.

New Accounting Standards to be Adopted in Future Periods

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and early adoption is permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017. Our evaluation of this standard is currently ongoing, and we expect to adopt ASU 2017-04 effective on January 1, 2020.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This standard is effective for fiscal years beginning after December 15, 2019, and early adoption is permitted for any interim period after issuance of the ASU. Our evaluation of this standard is currently ongoing, and we expect to adopt ASU 2018-18 effective on January 1, 2020.

3. Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs at a point in time when the transfer of risk and title to the product transfers to the customer. Our standard terms of delivery are included in our contracts of sale, order confirmation documents, and invoices. As such, all revenue is considered revenue recognized from contracts with customers, and we do not have other sources of revenue. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Revenue is recognized net of sales tax, value-added taxes, and other taxes. Shipping and other transportation costs charged to customers are recorded in both revenue and cost of goods sold. We do not have any material significant payment terms as payment is received at or shortly after the point of sale. Certain customers may receive cash-based incentives (including rebates, price supports, and sales commission), which are accounted for as variable consideration. We estimate rebates and price supports based on the expected amount to be provided to customers and reduce revenues recognized once the performance obligation has been met. Sales commissions are recorded as an increase in cost of goods sold once the performance obligation has been met. We do not expect to have significant changes in our estimates for variable considerations.

We have deferred revenue of $13.2 million related to contractual commitments with customers for which the performance obligation will be satisfied over time, which will range from one to ten years. The revenue associated with these performance obligations is recognized as the obligation is satisfied, which occurs as a volume based metric over time when the transfer of risk and title of finished products transfer to the customer.

Occasionally, we enter into bill-and-hold contracts, where we invoice the customer for products even though we retain possession of the products until a point in time in the future when the products will be shipped to the customer. In these contracts, the primary performance obligation is satisfied at a point in time when the product is segregated from our general inventory, it is ready for shipment to customer, and we do not have the ability to use the product or direct it to another customer. Additionally, we have a secondary performance obligation related to custodial costs, including storage and freight, which is satisfied over time once the product has been delivered to the customer. During the three and six months ended June 30, 2019, we recognized $0.3 million and $6.0 million of revenue related to these arrangements, respectively. During the three and six months ended June 30, 2018, we recognized $0.7 million and $4.5 million of revenue related to these arrangements, respectively.

13

We disaggregate our revenue by segment product lines, which is how we market our products and review results of operations. The following tables disaggregate our segment revenue by major product lines:

____________________________________________________ 

(1) Contract receivables are recorded within receivables, net of allowances on our Condensed Consolidated Balance Sheets.

(2) Our contract liability decreased by $0.6 million, as a result of meeting the performance obligation, which was recognized in our Specialty Polymers product line revenue, and decreased approximately $0.1 million due to the change in currency exchange rates.

4. Share-Based Compensation

We account for share-based awards under the provisions of ASC 718, Compensation—Stock Compensation. Accordingly, share-based compensation cost is measured at the grant date based on the fair value of the award, and we expense these costs using the straight-line method over the requisite service period, generally three years. Share-based compensation expense was $2.2 million for both the three months ended June 30, 2019 and 2018, respectively, and $5.5 million and $5.1 million for the six months ended June 30, 2019 and 2018, respectively.

6. Earnings Per Share (“EPS”)

Basic EPS is computed by dividing net income attributable to Kraton by the weighted-average number of shares outstanding excluding non-vested restricted stock awards during the period. Diluted EPS is computed by dividing net income attributable to Kraton by the diluted weighted-average number of shares outstanding during the period and, accordingly, reflects the potential dilution that could occur if securities or other agreements to issue common stock, such as stock options, were exercised, settled, or converted into common stock and were dilutive. The diluted weighted-average number of shares used in our diluted EPS calculation is determined using the treasury stock method.

The calculations of basic and diluted EPS are as follows:

	Three Months Ended June 30, 2019							Three Months Ended June 30, 2018

Share Repurchase Program. In February 2019, we announced a repurchase program for up to $50.0 million of the Company's common stock by March 2021. Repurchases may be made at management's discretion from time to time through privately-negotiated transactions, in the open market, or through broker-negotiated purchases in compliance with applicable securities law, including through a 10b5-1 Plan. The repurchase program may be suspended for periods or discontinued at any time, and the amount and timing of the repurchases are subject to a number of factors, including Kraton's stock price. During the six months ended June 30, 2019, we repurchased 152,986 shares of our common stock at an average price of $32.68 per share and a total cost of $5.0 million. We are not obligated to acquire any specific number of shares of our common stock.

Senior Secured Term Loan Facility. As of June 30, 2019, we had outstanding borrowings under the U.S. dollar denominated tranche (the “USD Tranche”) of our senior secured term loan facility (the “Term Loan Facility”) of $362.0 million and outstanding borrowings under the Euro denominated tranche (the “Euro Tranche”) of the Term Loan Facility of €300.0 million (or approximately $341.6 million). Our USD Tranche interest rate applicable margin is 2.5% and our alternative base rate applicable margin is 1.5%. The Euro Tranche interest rate applicable margin is 2.0%. Our Term Loan Facility will mature on March 8, 2025. For a summary of additional terms of the Term Loan Facility, see Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

As of the date of this filing, the effective interest rate for the USD Tranche is 4.29% and the effective interest rate for the Euro Tranche is 2.75%. The Term Loan Facility contains a number of customary affirmative and negative covenants, and we were in compliance with those covenants as of the date of this filing.

7.0% Senior Notes due 2025. Kraton Polymers LLC and its wholly-owned financing subsidiary Kraton Polymers Capital Corporation issued $400.0 million aggregate principal amount of 7.0% Senior Notes due 2025 (the “7.0% Senior Notes”) in March 2017, which mature on April 15, 2025. The 7.0% Senior Notes are general unsecured, senior obligations, and are unconditionally guaranteed on a senior unsecured basis by each of Kraton Corporation and certain of our wholly-owned domestic subsidiaries. We pay interest on the senior notes at 7.0% per annum, semi-annually in arrears on January 15 and July 15 of each year.

On December 6, 2018, we commenced a repurchase program for up to $20.0 million of our 7.0% Senior Notes. Purchases under the program took place from time to time in the open market and through privately negotiated transactions, including pursuant to a 10b5-1 Plan. During the six months ended June 30, 2019, we repurchased $4.3 million of our 7.0% Senior Notes. We recorded a $0.2 million gain on extinguishment of debt during the six months ended June 30, 2019, which includes a write off of $0.1 million related to previously capitalized deferred financing costs. The repurchase program ended March 4, 2019.

5.25% Senior Notes due 2026. Kraton Polymers LLC and its wholly-owned financing subsidiary Kraton Polymers Capital Corporation issued €290.0 million (or approximately $330.2 million as of June 30, 2019) aggregate principal amount of 5.25% Senior Notes due 2026 (the “5.25% Senior Notes”) in May 2018, which mature on May 15, 2026. The 5.25% Senior Notes are general unsecured, senior obligations, and are unconditionally guaranteed on a senior unsecured basis by each of Kraton Corporation and certain of our wholly-owned domestic subsidiaries. We pay interest on the senior notes at 5.25% per annum, semi-annually in arrears on May 15 and November 15 of each year.

ABL Facility. Our asset-based revolving credit facility provides financing of up to $250.0 million (the “ABL Facility”). The ABL Facility also provides that we have the right at any time to request up to $100.0 million of additional commitments, provided that we satisfy certain additional conditions. Our outstanding borrowings under the ABL facility were $27.0 million as of June 30, 2019. The ABL Facility matures on January 6, 2021.

19

Borrowing availability under the ABL Facility is subject to borrowing base limitations based on the level of receivables and inventory available for security. Revolver commitments under the ABL Facility consist of U.S. and Dutch revolving credit facility commitments, and the terms of the ABL Facility require the U.S. revolver commitment comprises at least 60.0% of the commitments under the ABL Facility. The ABL Facility contains a number of customary affirmative and negative covenants, and we were in compliance with those covenants as of the date of this filing. For a summary of additional terms of the ABL Facility, see Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

KFPC Loan Agreement. As of June 30, 2019, NTD 3.0 billion (or approximately $95.4 million) was drawn on KFPC's syndicated loan agreement (the “KFPC Loan Agreement”). For the three and six months ended June 30, 2019, our effective interest rate for borrowings on the KFPC Loan Agreement was 1.8%. The KFPC Loan Agreement contains certain financial covenants that change during the term of the KFPC Loan Agreement. KFPC was in compliance with certain covenants as of the date of this filing. Additionally, due to a waiver received from the majority of lenders, we are no longer subject to the remaining 2019 financial covenants. In each case, these covenants are calculated and tested on an annual basis at December 31^st each year.

The KFPC Loan Agreement matures January 17, 2020. Subject to the terms within the KFPC Loan Agreement, we expect to elect the extension provision whereby we have the option, up to six months prior to the final maturity date, to apply to the facility agent in writing for an extension of the facility period for another two years, or January 17, 2022. We anticipate approvals by the lender syndicate by end of the third quarter 2019. For a summary of additional terms of the KFPC Loan Agreement, see Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

KFPC Revolving Facilities. KFPC also has five revolving credit facilities (the “KFPC Revolving Facilities”) to provide funding for working capital requirements and/or general corporate purposes, which allow for total borrowings of up to NTD 2.2 billion (or approximately $69.2 million). All of the KFPC Revolving Facilities are subject to variable interest rates. As of June 30, 2019, NTD 450.0 million (or approximately $14.5 million) was drawn on the KFPC Revolving Facilities.

Debt Issuance Costs. We had net debt issuance cost of $27.0 million as of June 30, 2019, of which $1.8 million related to the ABL Facility which is recorded as an asset (of which $1.2 million was included in other current assets) and $25.3 million is recorded as a reduction to long-term debt. We amortized $1.2 million and $1.4 million for the three months ended June 30, 2019, and 2018, respectively, and $2.3 million and $3.3 million during the six months ended June 30, 2019 and 2018, respectively.

Debt Maturities. The remaining principal payments on our outstanding total debt as of June 30, 2019, are as follows:

	Principal Payments

See Note 8 Fair Value Measurements, Financial Instruments, and Credit Risk for fair value information related to our long-term debt.

8. Fair Value Measurements, Financial Instruments, and Credit Risk

ASC 820, Fair Value Measurements and Disclosures defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value measurements. ASC 820 requires entities to, among other things, maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

ASC 820 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 our market assumptions.

20

In accordance with ASC 820, these two types of inputs have created the following fair value hierarchy:

• Level 1—Inputs that are quoted prices (unadjusted) for identical assets or liabilities in active markets;

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability, including:

• Quoted prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in markets that are not active;

• Inputs other than quoted prices that are observable for the asset or liability; and

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means; and

• Level 3—Inputs that are unobservable and reflect our assumptions used in pricing the asset or liability based on the best information available under the circumstances (e.g., internally derived assumptions surrounding the timing and amount of expected cash flows).

Recurring Fair Value Measurements. The following tables set forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2019 and December 31, 2018. These financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which judgment may affect the valuation of their fair value and placement within the fair value hierarchy levels. As of June 30, 2019 and December 31, 2018, the Company has no assets or liabilities utilizing significant unobservable inputs (or Level 3) to derive its estimated fair values.

The ABL Facility, Capital lease obligation, KFPC Loan Agreement, and KFPC Revolving Facilities are variable rate instruments, and as such, the fair value approximates the carrying value.

Financial Instruments    

Interest Rate Swap Agreements. Periodically, we enter into interest rate swap agreements to hedge or otherwise protect against interest rate fluctuation on a portion of our variable rate debt. These interest rate swap agreements are designated as cash flow hedges on our exposure to the variability of future cash flows.

In an effort to convert a substantial portion of our future interest payments pursuant to the USD Tranche to a fixed interest rate, in February and March 2016 we entered into several interest rate swap agreements with an aggregate notional value of $925.4 million, effective dates of January 3, 2017 and maturity dates of December 31, 2020. In May 2018 we entered into an interest rate swap agreement with a notional value of $90.0 million, effective date of June 4, 2018 and maturity date of December 31, 2018. We exited out of $715.4 million of our interest rate swaps as of December 31, 2018, including the expiration of the notional value of $90.0 million interest rate swap agreement entered into in May 2018. As a result, at June 30, 2019, the total notional value of our interest rate swaps was $300.0 million, which effectively hedges the outstanding USD Tranche, fixing LIBOR at 1.608%. We recorded an unrealized loss of $2.6 million and an unrealized gain of $0.9 million for the three months ended June 30, 2019 and 2018, respectively, and an unrealized loss of $4.3 million and an unrealized gain of $4.6 million during the six months ended June 30, 2019 and 2018, respectively, in other comprehensive income (loss) related to the effective portion of these interest rate swap agreements. In addition, we reclassified out of other comprehensive income (loss) the settlement of a portion of our interest rate swap that amounted to a $2.6 million gain for the six months ended June 30, 2018.

Foreign Currency Hedges. Periodically, we enter into foreign currency agreements to hedge or otherwise protect against fluctuations in foreign currency exchange rates. These agreements do not qualify for hedge accounting, and gains/losses resulting from both the up-front premiums and/or settlement of the hedges at expiration of the agreements are recognized in the period in which they are incurred. We settled these hedges and recorded a gain of $0.3 million and a loss of $0.2 million for the three months ended June 30, 2019 and 2018, respectively, and a loss of $1.9 million and $0.2 million for the six months ended June 30, 2019 and 2018, respectively, which are recorded in cost of goods sold in the Condensed Consolidated Statements of Operations. These contracts are structured such that these gains/losses from the mark-to-market impact of the hedging instruments materially offset the underlying foreign currency exchange gains/losses to reduce the overall impact of foreign currency exchange movements throughout the period.

Net Investment Hedge. During the year ended December 31, 2018, we designated €290.0 million of euro-denominated borrowing as a hedge against a portion of our net investment in the Company's European operations. The mark to market of this instrument was a gain of $1.3 million and $3.5 million for the six months ended June 30, 2019 and 2018, respectively, which is recorded within accumulated other comprehensive income (loss) in the Condensed Consolidated Balance Sheets.

Credit Risk

The use of derivatives creates exposure to credit risk in the event that the counterparties to these instruments fail to perform their obligations under the contracts, which we seek to minimize by limiting our counterparties to major financial institutions with acceptable credit ratings and by monitoring the total value of positions with individual counterparties.

22

We analyze our counterparties’ financial condition prior to extending credit, and we establish credit limits and monitor the appropriateness of those limits on an ongoing basis. We also obtain cash, letters of credit, or other acceptable forms of security from customers to provide credit support, where appropriate, based on our financial analysis of the customer and the contractual terms and conditions applicable to each transaction.

9. Income Taxes

Our income tax provision was a benefit of $6.8 million and $1.8 million for the three months ended June 30, 2019 and 2018, respectively, and a benefit of $4.2 million and an expense of $0.4 million for the six months ended June 30, 2019 and 2018, respectively. Our effective tax rate was 18.7% and 11.6% for the three months ended June 30, 2019 and 2018, respectively, and 7.9% and 4.9% for the six months ended June 30, 2019 and 2018, respectively. During the six months ended June 30, 2019, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various foreign jurisdictions, the tax impact of certain permanent items, and our uncertain tax positions, particularly the release from the closing of the U.S tax audit. During the six months ended June 30, 2018, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various foreign jurisdictions and our uncertain tax positions.

The provision for income taxes differs from the amount computed by applying the U.S. corporate statutory income tax rate to income (loss) before income taxes for the reasons set forth below.

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Income taxes at the statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State taxes, net of federal benefit	1.3		1.3		1.3		1.8
Foreign tax rate differential	(9.2	)	8.5		(6.3	)	(50.2	)
Permanent differences	7.3		(11.8	)	2.1		(1.7	)
Uncertain tax positions	(38.4	)	(3.3	)	(25.4	)	12.6
Valuation allowance	(0.8	)	(4.0	)	(0.8	)	5.3
Return to provision adjustments	0.1		(0.1	)	0.2		16.1
Other	—		—		—		—
Effective tax rate	(18.7	)%	11.6	%	(7.9	)%	4.9	%

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. We consider all available material evidence, both positive and negative, in assessing the appropriateness of a valuation allowance for our deferred tax assets. In determining whether a valuation allowance is required during the period, we evaluate primarily (a) cumulative earnings and losses in recent years, (b) historical taxable income or losses as it relates to our ability to utilize operating loss and tax credit carryforwards within the expiration period, (c) trends indicating earnings or losses expected in future years along with our ability in prior years to reasonably project these future trends or operating results, (d) length of the carryback and carryforward period, and (e) prudent and feasible tax-planning strategies, particularly related to operational changes and the impact on the timing or taxability of relative amounts.

As of June 30, 2019 and December 31, 2018, we recorded a valuation allowance of $42.1 million and $42.5 million, respectively, against our net operating loss carryforwards and other deferred tax assets. We decreased our valuation allowances by $0.3 million and $0.4 million for the three and six months ended June 30, 2019, respectively, primarily related to current period utilization of net operating loss carryforwards in certain jurisdictions. We increased our valuation allowances by $0.6 million and $0.4 million for the three and six months ended June 30, 2018, respectively, primarily related to current period net operating losses in the U.S.

For the period ending June 30, 2019, a portion of the unremitted foreign earnings are permanently reinvested in the corresponding country of origin. Accordingly, we have not provided deferred taxes for the differences between the book basis and underlying tax basis in those subsidiaries or on the foreign currency translation adjustment amounts related to such operations.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. For our U.S. federal income tax returns, the statute of limitations has expired through the tax year ended December 31, 2003. As a result of net operating loss carryforwards from 2004, the statute remains open for all years subsequent to 2003. In addition, open tax years for state and foreign jurisdictions remain subject to examination.

23

We recognize the tax impact of certain tax positions only when it is more likely than not those such positions are sustainable. The taxes are recorded in accordance with ASC 740-10, Accounting for Uncertainty in Income Taxes, which prescribes the minimum recognition threshold.

As of June 30, 2019 and December 31, 2018, we had total unrecognized tax benefits of $16.1 million and $29.6 million, respectively, related to uncertain tax positions, all of which, if recognized, would impact our effective tax rate. During the three and six months ended June 30, 2019, we had a decrease of $13.9 million and $13.5 million, respectively, primarily related to the closing of the U.S. tax audit for the pre-acquisition tax return filing. During the three and six months ended June 30, 2018, we had an increase of $0.1 million and $0.9 million, respectively, primarily related to our uncertain tax positions in the U.S. and Europe. We recorded interest and penalties related to unrecognized tax benefits within the provision for income taxes. For the year ending December 31, 2019, we expect to release $19.7 million in reserves, of which $14.0 million was released during the three months ended June 30, 2019 as a result of the closing of certain U.S. tax audits.

The Tax Cuts and Jobs Act enacted on December 22, 2017 (the “Tax Act”) introduced significant changes to U.S. income tax law. Effective 2018, the Tax Act reduced the U.S. statutory tax rate from 35.0% to 21.0% and created new taxes on certain foreign-sourced earnings and certain related-party payments.

One-time transition tax

The Tax Act required us to pay U.S. income taxes on accumulated foreign subsidiary earnings not previously subject to U.S. income tax at a rate of 15.5% to the extent of foreign cash and certain other net current assets and 8.0% on the remaining earnings. Related to the 2017 tax year, we recorded a $15.7 million one-time transitional tax liability. Any legislative changes, including the final Section 965 transition tax regulations issued on January 15, 2019, whose impact is currently being assessed due to the complexity and interdependency of the legislative provisions, as well as any other new or proposed Treasury regulations, which have yet to be issued, may result in additional income tax impacts which could be material in the period any such changes are enacted.

Deferred tax effects

Due to the change in the statutory tax rate from the Tax Act, we remeasured our deferred taxes as of December 31, 2017 to reflect the reduced rate that will apply in future periods when these deferred taxes are settled or realized. We recognized a deferred tax benefit of $95.0 million, of which $68.9 million relates to the reduction of the U.S. statutory tax rate from 35.0% to 21.0% for years after 2017 and the remaining relates to changes in our investments in foreign subsidiaries. For the period ending December 31, 2018, we completed our analysis based on legislative updates relating to the Tax Act and made no adjustments to the provisional amounts previously recorded.

10. Commitments and Contingencies

(a) Lease Commitments - accounted for under ASC 842 Leases

Substantially all our operating lease ROU assets and operating lease liability represents leases, with a term greater than one year, for railcars, office space, and equipment used to conduct our operations. We currently have no finance leases. These leases were discounted using a rate of 3.125%, which is based on a weighted average borrowing rate of specific debt. Non-variable lease costs include the amortization of the asset recorded on a straight-line basis. Variable lease components are non-index based payments based on performance or usage of the underlying asset. We have no material lessor or sublease income.

The components of lease cost for operating leases are as follows:

(b) Legal Proceedings

We received an initial notice from the tax authorities in Brazil during the fourth quarter of 2012 in connection with tax credits that were generated from the purchase of certain goods which were subsequently applied by us against taxes owed. The tax authorities are currently assessing R$9.6 million, or approximately $2.5 million. We have appealed the assertion by the tax authorities in Brazil that the goods purchased were not eligible to earn the credits. While the outcome of this proceeding cannot be predicted with certainty, we do not expect this matter to have a material adverse effect upon our financial position, results of operations or cash flows.

We and certain of our subsidiaries, from time to time, are parties to various other legal proceedings, claims and disputes that have arisen in the ordinary course of business. These claims may involve significant amounts, some of which would not be covered by insurance. A substantial settlement payment or judgment in excess of our accruals could have a material adverse effect on our financial position, results of operations or cash flows. While the outcome of these proceedings cannot be predicted with certainty, we do not expect any of these existing matters, individually or in the aggregate, to have a material adverse effect upon our financial position, results of operations or cash flows.

Ending balance	$	5,659		$	5,699

Pursuant to the indemnity included in the February 2001 separation agreement from Shell Chemical, we recorded a receivable of $0.2 million as of June 30, 2018.

Except for the presentation on the Condensed Consolidated Balance Sheets for the impact of ASU 842, there have been no other material changes to our Commitments and Contingencies disclosed in our most recently filed Annual Report on Form 10-K.

The components of net periodic benefit costs other than the service cost component are included in Other expense on our Condensed Consolidated Statements of Operations.

We made contributions of $6.5 million and $6.6 million to our pension plans in the six months ended June 30, 2019 and 2018, respectively.

The components of net periodic benefit cost related to other post-retirement benefits are as follows:

	Three Months Ended June 30,					Six Months Ended June 30,

Amortization of net actuarial loss	175			—		350			—
Net periodic benefit cost	$	67		$	662	$	135		$	1,340

During the year ended December 31, 2018, we amended the post-retirement benefits plan for post-65 retirees to provide an annual subsidy based on years of service. The annual subsidy replaces a company-sponsored medical plan. This plan modification resulted in a $13.1 million reduction in pension and other post-retirement liabilities during the year ended December 31, 2018.

The components of net periodic benefit costs other than the service cost component are included in Other expense on our Condensed Consolidated Statements of Operations.

12. Industry Segments and Foreign Operations

Our operations are managed through two operating segments: (i) Polymer segment; and (ii) Chemical segment. In accordance with the provisions of ASC 280, Segment Reporting, our chief operating decision maker has been identified as our President and Chief Executive Officer, who reviews operating results to make decisions about allocating resources and assessing performance for the entire company.

• Polymer Segment is comprised of our SBCs and other engineered polymers business.

• Chemical Segment is comprised of our pine-based specialty products business.

Our chief operating decision maker uses operating income (loss) as the primary measure of each segment's operating results in order to allocate resources and in assessing the company's performance. In accordance with ASC 280, Segment Reporting, we have presented operating income for each segment. The following table summarizes our operating results by segment. We do not have sales between segments.

Our capital expenditures for the Polymer segment, excluding capital expenditures by the KFPC joint venture, were $29.9 million and $19.5 million during the six months ended June 30, 2019 and 2018, respectively, and capital expenditures for our Chemical segment were $20.1 million and $22.7 million during the six months ended June 30, 2019 and 2018, respectively.

Impact of Hurricane Michael

During the six months ended June 30, 2019, we incurred an incremental $12.8 million of direct costs as we continued to ramp production back to operating capacity. Our insurance carrier provided an additional $17.5 million of advance reimbursement under our insurance policies, recorded as a gain on insurance proceeds in the Condensed Consolidated Statement of Operations (including $1.1 million of proceeds received during the fourth quarter of 2018, but which was deferred at that time as unearned until realizable, during the first quarter of 2019). The $18.6 million gain on insurance fully offsets the lost margin in the first quarter of 2019 and reimburses us for a portion of the direct costs we have incurred to date. We currently estimate the replacement cost associated with damaged equipment to be in a range of $9.0 million to $11.0 million. We have spent $5.6 million as of June 30, 2019. We continue to work with our insurance carriers to resolve all claims under our business interruption and property coverage.

13. Related Party Transactions

We own a 50% equity investment in an SBC manufacturing joint venture in Kashima, Japan. Our outstanding payables were $16.5 million and $20.1 million as of June 30, 2019 and December 31, 2018, respectively, which were recorded in “Due to related party” liability on the Condensed Consolidated Balance Sheets. Our total purchases from the joint venture were $8.2 million and $7.2 million for the three months ended June 30, 2019 and 2018, respectively, and $16.4 million and $16.3 million for the six months ended June 30, 2019 and 2018, respectively.

We own a 50% variable interest in KFPC, an HSBC manufacturing joint venture in Mailiao, Taiwan. The KFPC joint venture is fully consolidated in our financial statements, and our joint venture partner, Formosa Petrochemical Corporation (“FPCC”), is a related party affiliate. Under the terms of the joint venture agreement, FPCC is to provide certain site services and raw materials to KFPC. Additionally, we purchase certain raw materials from FPCC for our other manufacturing locations. Our outstanding payables were $0.7 million and $0.8 million as of June 30, 2019 and December 31, 2018, respectively, which were recorded in “Due to related party” liability on the Condensed Consolidated Balance Sheets. Our total purchases from this joint venture were $13.6 million and $7.4 million for the three months ended June 30, 2019 and 2018, respectively, and $25.4 million and $13.1 million for the six months ended June 30, 2019 and 2018, respectively. See Note 14 Variable Interest Entity, for further discussion related to the KFPC joint venture.

14. Variable Interest Entity

We hold a variable interest in a joint venture with FPCC to own and operate a 30 kiloton HSBC plant at FPCC’s petrochemical site in Mailiao, Taiwan. Included in the below assets and liabilities is a land lease with FPCC to support our operations at the HSBC plant. Kraton and FPCC are each 50% owners of the joint venture company, KFPC. Under the provisions of an offtake agreement with KFPC, we have exclusive rights to purchase all production from KFPC. Additionally, following a ramp-up period, the agreement requires us to purchase a minimum of 80% of the plant production capacity each year at a defined fixed margin. This offtake agreement represents a variable interest that provides us the power to direct the most significant activities of KFPC and exposes us to the economic variability of the joint venture. As such, we have determined that we are the primary beneficiary of this variable interest entity. As a result, we have consolidated KFPC in our financial statements and reflected FPCC’s 50% ownership as a noncontrolling interest.

The following table summarizes the carrying amounts of assets and liabilities as of June 30, 2019 and December 31, 2018 for KFPC before intercompany eliminations.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

INTRODUCTION

You should read the following discussion of our financial condition and results of operations together with our audited consolidated financial statements and related notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. This discussion contains forward-looking statements and involves numerous risks, uncertainties, assumptions and other important factors that could cause the actual results, performance, or industry results, to differ materially from historical results, any future results, or performance, or industry results expressed or implied by such forward-looking statements. See “Cautionary Statement Regarding Forward-Looking Information.”

OVERVIEW

We are a leading global specialty chemicals company that manufactures styrenic block copolymers (“SBCs”), specialty polymers, and high-value performance products primarily derived from pine wood pulping co-products. Our operations are managed through two operating segments: (i) Polymer segment and (ii) Chemical segment.

Polymer Segment

SBCs are highly-engineered synthetic elastomers, which we invented and commercialized over 50 years ago. We developed the first unhydrogenated styrenic block copolymers (“USBC”) in 1964 and the first hydrogenated styrenic block copolymers (“HSBC”) in the late 1960s. Our SBCs enhance the performance of numerous products by imparting greater flexibility, resilience, strength, durability, and processability, and are used in a wide range of applications, including adhesives, coatings, consumer and personal care products, sealants, lubricants, medical, packaging, automotive, paving, roofing, and footwear products. We also sell isoprene rubber (“IR”) and isoprene rubber latex (“IRL”), which are non-SBC products primarily used in applications such as medical products, personal care, adhesives, tackifiers, paints, and coatings.

Our polymers are typically formulated or compounded with other products to achieve improved, customer-specific performance characteristics in a variety of applications. We seek to maximize the value of our product portfolio by emphasizing complex or specialized polymers and innovations that yield higher margins than more commoditized products. We sometimes refer to these complex or specialized polymers or innovations as being more “differentiated.”

Our paving and roofing applications provide durability, extending road and roof life. Our products are also found in medical applications, personal care products such as disposable diapers, oil additives, gels, and various other consumer goods. Our products are also used to impart tack and shear properties in a wide variety of adhesive products and to impart characteristics such as flexibility and durability in sealants and corrosion resistance in coatings.

We also produce Cariflex^TM isoprene rubber and isoprene rubber latex. Our Cariflex products are based on synthetic polyisoprene polymer and do not contain natural rubber latex or other natural rubber products, making them an ideal substitute for natural rubber latex, particularly in applications with high purity requirements such as medical, healthcare, personal care, and food contact. We believe the versatility of Cariflex provides opportunities for new, differentiated applications.

Chemical Segment

We manufacture and sell high value products primarily derived from pine wood pulping co-products. We refine and further upgrade two primary feedstocks, crude tall oil (“CTO”) and crude sulfate turpentine (“CST”), both of which are co-products of the wood pulping process, into value-added specialty chemicals. We refine CTO through a distillation process into four primary constituent fractions: tall oil fatty acids (“TOFA”); tall oil rosin (“TOR”); distilled tall oil (“DTO”); and tall oil pitch. We further upgrade TOFA, TOR, and DTO into derivatives such as dimer acids, polyamide resins, rosin resins, dispersions, and disproportionated resins. We refine CST into terpene fractions, which can be further upgraded into terpene resins. The various fractions and derivatives resulting from our CTO and CST refining process provide for distinct functionalities and properties, determining their respective applications and end markets.

We focus our resources on three product groups: Adhesives, Performance Chemicals, and Tires. Within our product groups, our products are sold into a diverse range of submarkets, including packaging, tapes and labels, pavement marking, high performance tires, fuel additives, oilfield and mining, coatings, metalworking fluids and lubricants, inks, and flavor and fragrances, among others.

While this business is based predominantly on the refining and upgrading of CTO and CST, we have the capacity to use both hydrocarbon-based raw materials, such as alpha-methyl-styrene, rosins, and gum rosins where appropriate and, accordingly, are able to offer tailored solutions for our customers.

31

Factors Affecting Our Results of Operations

International Operations and Currency Fluctuations. We operate a geographically diverse business, serving customers in numerous countries from fourteen manufacturing facilities on four continents. Our sales and production costs are mainly denominated in U.S. dollars, Euro, Japanese Yen, Swedish Krona, and Brazilian Real. From time to time, we use hedging strategies to reduce our exposure to currency fluctuations.

We generated our revenue from customers located in the following regions:

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Revenue by Geography:	(In thousands)
Americas	$	211,456	$	231,562	$	401,729	$	441,640

Total revenue	$	495,280	$	538,395	$	951,691	$	1,040,787

Raw Materials. We use butadiene, styrene, and isoprene (collectively referred to as “monomers”) as our primary raw materials in our Polymer segment and CTO and CST in our Chemical segment. The cost of these raw materials has generally correlated with changes in energy prices and is generally influenced by supply and demand factors, and for our isoprene monomers, the prices of natural and synthetic rubber. Average purchase prices of our raw materials decreased for the Polymer segment and increased for the Chemical segment during the three months ended June 30, 2019 compared to the three months ended June 30, 2018. Average purchase prices of our raw materials decreased for the Polymer segment and increased for the Chemical segment during the six months ended June 30, 2019 compared to the six months ended June 30, 2018.

Seasonality. Seasonal changes and weather conditions typically affect our sales of products in our paving, pavement marking, roofing, and construction applications, which generally results in higher sales volumes in the second and third quarters of the calendar year compared to the first and fourth quarters of the calendar year. Sales for our other product applications tend to show relatively little seasonality.

Recent Developments and Certain Known Trends

Our business is subject to a number of known risks and uncertainties, some of which are a result of recent developments.

Tariffs. Effective September 24, 2018, the Office of the U.S. Trade Representative enacted a 10.0% tariff on certain goods imported from China under Section 301 of the Trade Expansion Act of 1974, which increased up to 25.0% in 2019 on raw material imports of ours. In addition, China has enacted tariffs on certain goods imported into China from the United States ranging from 0.0% to 25.0% impacting our sales into China during 2019. We have implemented certain mitigation efforts to minimize the effects of any pricing and supply conditions.

Hurricane Michael. In October 2018, our Panama City, Florida, facility was damaged by Hurricane Michael. In November 2018, restoration of operations for the CTO refinery were complete. Our CST refinery was restored to full operational capacity during the first quarter of 2019.

During the six months ended June 30, 2019, we estimate the margin associated with lost sales due to Hurricane Michael to be $5.9 million, and we incurred an incremental $12.8 million of direct costs as we continued to ramp production back to operating capacity. Our insurance carrier provided an additional $17.5 million of advance reimbursement under our insurance policies. The $18.6 million gain on insurance, recorded as a gain on insurance proceeds in the Condensed Consolidated Statement of Operations (including $1.1 million of proceeds received during the fourth quarter of 2018, but which was deferred at that time as unearned until realizable, during the first quarter of 2019) fully offsets the lost margin in the first quarter of 2019 and reimburses us for a portion of the direct costs we have incurred to date. We currently estimate the replacement cost associated with damaged equipment to be in a range of $9.0 million to $11.0 million. We have spent $5.6 million as of June 30, 2019. We continue to work with our insurance carriers to resolve all claims under our business interruption and property coverage.

Logistics cost. We, like many others, have experienced an increase in transportation and logistics costs. The higher costs began for us in 2018, and we believe are the result of a shortage of U.S. truck drivers, coupled with a recent consolidation of ocean freight carriers. This is a trend we expect to continue throughout 2019.

32

Strategic alternatives for Cariflex business. In February 2019, the Company's board of directors initiated a process to review strategic alternatives for our Cariflex business, which may result in a sale of that business. The initial phase of due diligence is in the process of being completed. There can be no assurance that the strategic review of Cariflex will result in the completion of a transaction. The Company's board of directors has not set a timetable for the completion of the strategic review. As of June 30, 2019, no assets are classified as held for sale.

Consolidated Results

Three Months Ended June 30, 2019 compared to Three Months Ended June 30, 2018

Revenue was $495.3 million for the three months ended June 30, 2019 compared to $538.4 million for the three months ended June 30, 2018, a decrease of $43.1 million or 8.0%. Revenue declined $40.3 million and $2.8 million for the Polymer and Chemical segment, respectively. For additional information regarding the changes in revenue, see our segment disclosures below.

Cost of goods sold was $366.1 million for the three months ended June 30, 2019 compared to $367.7 million for the three months ended June 30, 2018, a decrease of $1.6 million or 0.4%. Cost of goods sold decreased $9.3 million for the Polymer segment and increased $7.7 million for the Chemical segment. For additional information regarding the changes in cost of goods sold, see our segment disclosures below.

Selling, general, and administrative expenses were $38.5 million for the three months ended June 30, 2019 compared to $42.0 million for the three months ended June 30, 2018. The $3.5 million decrease is primarily attributable to lower employee related costs, partially offset by higher transaction, acquisition, and restructuring costs.

34

Depreciation and amortization was $31.9 million for the three months ended June 30, 2019 compared to $35.1 million for the three months ended June 30, 2018. The decrease of $3.2 million was primarily attributable to certain assets being fully depreciated as of December 31, 2018 and impacts from foreign exchange rates.

We recorded a $72.3 million loss on extinguishment of debt during the three months ended June 30, 2018, which includes the write off of previously capitalized deferred financing costs and original issue discount, as well as the tender offer and subsequent redemption of our 10.5% Senior Notes. See Note 7 Long-Term Debt to the consolidated financial statement included in this Quarterly Report on Form 10-Q.

Interest expense, net, was $19.3 million for the three months ended June 30, 2019 compared to $25.4 million for the three months ended June 30, 2018, a decrease of $6.1 million. The decrease is due to refinancing activities and lower overall indebtedness.

Income tax provision was a benefit of $6.8 million and $1.8 million for the three months ended June 30, 2019 and 2018, respectively. Our effective tax rate was 18.7% and 11.6% for the three months ended June 30, 2019 and 2018, respectively. During the three months ended June 30, 2019, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various foreign jurisdictions, the tax impact of certain permanent items, and our uncertain tax positions, particularly the release from the closing of the U.S tax audit. During the three months ended June 30, 2018, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various jurisdictions and permanent items.

Net income attributable to Kraton was $41.2 million, or $1.28 per diluted share, for the three months ended June 30, 2019, an increase of $56.1 million compared to net loss of $14.9 million, or $0.47 per diluted share, for the three months ended June 30, 2018. Adjusted Diluted Earnings Per Share (non-GAAP) was $1.58 for the three months ended June 30, 2019 compared to Adjusted Diluted Earnings Per Share (non-GAAP) of $0.88 for the three months ended June 30, 2018. See a reconciliation of generally accepted accounting principles (“GAAP”) Diluted Earnings (Loss) Per Share to non-GAAP Adjusted Diluted Earnings (Loss) Per Share below.

Six Months Ended June 30, 2019 compared to Six Months Ended June 30, 2018

Revenue was $951.7 million for the six months ended June 30, 2019 compared to $1,040.8 million for the six months ended June 30, 2018, a decrease of $89.1 million or 8.6%. Revenue decreased $68.3 million and $20.8 million for the Polymer and Chemical segments, respectively. For additional information regarding the changes in revenue, see our segment disclosures below.

Cost of goods sold was $715.5 million for the six months ended June 30, 2019 compared to $723.0 million for the six months ended June 30, 2018, a decrease of $7.5 million or 1.0%. Cost of goods sold decreased $9.8 million for the Polymer segment and increased $2.3 million for the Chemical segment. For additional information regarding the changes in cost of goods sold, see our segment disclosures below.

Selling, general, and administrative expenses were $79.4 million for the six months ended June 30, 2019 compared to $80.7 million for the six months ended June 30, 2018. The $1.3 million decrease is primarily attributable to lower employee related costs, partially offset by higher transaction, acquisition, and restructuring costs.

Depreciation and amortization was $63.4 million for the six months ended June 30, 2019 compared to $70.5 million for the six months ended June 30, 2018. The decrease of $7.1 million was primarily attributable to certain assets being fully depreciated as of December 31, 2018 and impacts from foreign exchange rates.

We recorded a $79.9 million loss on extinguishment of debt during the six months ended June 30, 2018, which includes the write off of previously capitalized deferred financing costs and original issue discount, the tender offer and subsequent redemption of our 10.5% Senior Notes, partially offset by a gain on the settlement of the ineffective portion of interest rate swaps. See Note 7 Long-Term Debt to the consolidated financial statement included in this Quarterly Report on Form 10-Q.

Interest expense, net, was $38.3 million for the six months ended June 30, 2019 compared to $54.7 million for the six months ended June 30, 2018, a decrease of $16.4 million. The decrease is due to refinancing activities and lower overall indebtedness.

Our income tax provision was a benefit of $4.2 million and an expense $0.4 million for the six months ended June 30, 2019 and 2018, respectively. Our effective tax rate was 7.9% and 4.9% for the six months ended June 30, 2019 and 2018, respectively. During the six months ended June 30, 2019, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various foreign jurisdictions, the tax impact of certain permanent items, and our uncertain tax positions, particularly the release from the closing of the U.S tax audit. During the six months ended June 30, 2018, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various jurisdictions and permanent items.

Net income attributable to Kraton was $53.9 million, or $1.67 per diluted share, for the six months ended June 30, 2019, an increase of $46.7 million compared to net income of $7.1 million, or $0.22 per diluted share, for the six months ended June 30, 2018. Adjusted Diluted Earnings Per Share (non-GAAP) was $2.46 for the six months ended June 30, 2019 compared to Adjusted Diluted Earnings Per Share (non-GAAP) of $1.47 for the six months ended June 30, 2018.

Three Months Ended June 30, 2019 compared to Three Months Ended June 30, 2018

Revenue for the Polymer segment was $297.9 million for the three months ended June 30, 2019 compared to $338.2 million for the three months ended June 30, 2018. The decrease was driven by lower sales volumes, and to a lesser extent, lower average sales prices resulting from lower raw material costs. Sales volumes of 80.2 kilotons for the three months ended June 30, 2019 declined 8.6% compared to the three months ended June 30, 2018 sales volumes of 87.7 kilotons. Performance Products sales volumes decreased 13.9% due to a slow start to the paving and roofing season, as a result of poor weather conditions in North America and Europe, coupled with competitive pressures from Asia. Cariflex sales volumes increased 10.1% primarily from higher latex sales into surgical glove applications and Specialty Polymers sales volumes increased 1.9% due to higher sales into lubricant additive applications. The negative effect from changes in currency exchange rates between the periods was $9.9 million.

Cost of goods sold was $219.0 million for the three months ended June 30, 2019 compared to $228.3 million for the three months ended June 30, 2018, a decrease of $9.3 million or 4.1%. The decrease in cost of goods sold reflects lower sales volumes, and to a lesser extent, lower raw material costs. These decreases are partially offset by the cost of consumed raw materials, which has higher average costs on a first-in, first-out measurement basis of accounting. Additionally, changes in currency exchange rates between the periods resulted in a positive impact of $6.7 million.

For the three months ended June 30, 2019, the Polymer segment operating income was $35.0 million compared to $60.2 million for the three months ended June 30, 2018.

For the three months ended June 30, 2019, the Polymer segment generated Adjusted EBITDA (non-GAAP) of $60.2 million compared to $68.7 million for the three months ended June 30, 2018. The decline in Adjusted EBITDA was due to the aforementioned slow start to the paving and roofing season, coupled with competitive pressures from Asia, impacting sales in Performance Products. This was partially offset by higher sales volumes in the Cariflex product group. The negative effect from changes in currency exchange rates between the periods was $2.6 million. See a reconciliation of GAAP operating income to non-GAAP Adjusted EBITDA below.

Six Months Ended June 30, 2019 compared to Six Months Ended June 30, 2018

Revenue for the Polymer segment was $558.9 million for the six months ended June 30, 2019 compared to $627.2 million for the six months ended June 30, 2018. The decrease was driven by lower sales volumes, and to a lesser extent, lower average sales prices resulting from lower raw material costs. Sales volumes of 154.0 kilotons for the six months ended June 30, 2019 decreased 6.8% compared to the six months ended June 30, 2018. Specialty Products sales volumes decreased 9.0% as a result of economic slow down in China and greater Asia. The 7.4% decline in Performance Products sales volumes is largely associated with a slow start to the paving and roofing season, as a result of poor weather conditions in North America and Europe, coupled with competitive pressures from Asia. Cariflex sales volumes increased 7.8%, primarily from higher latex

36

sales into surgical glove applications. The negative impact from changes in currency exchange rates between the periods was $18.3 million.

Cost of goods sold was $426.2 million for the six months ended June 30, 2019 compared to $435.9 million for the six months ended June 30, 2018, a decrease of $9.8 million or 2.2%. The decrease in cost of goods sold reflects lower sales volumes, and to a lesser extent, lower raw material costs. These decreases are partially offset by the cost of consumed raw materials, which has higher average costs on a first-in, first-out measurement basis of accounting. These higher costs were partially offset by overall improved operating performance at our manufacturing sites. The positive effect from changes in currency exchange rates between the periods was $12.2 million.

For the six months ended June 30, 2019, the Polymer segment operating income was $44.2 million compared to $93.0 million for the six months ended June 30, 2018.

For the six months ended June 30, 2019, the Polymer segment generated Adjusted EBITDA (non-GAAP) of $108.3 million compared to $113.5 million for the six months ended June 30, 2018. The 4.5% decrease in Adjusted EBITDA is due to the economic slow down in China and greater Asia impacting sales of Specialty Polymers and the slow start to the paving and roofing season, coupled with competitive pressures from Asia, impacting sales in Performance Products. This was partially offset by overall improved operating performance and higher sales volumes in the Cariflex product group. The negative effect from changes in currency exchange rates between the periods was $4.0 million. See a reconciliation of GAAP operating income to non-GAAP Adjusted EBITDA below.

Three Months Ended June 30, 2019 compared to Three Months Ended June 30, 2018

Revenue for the Chemical segment was $197.4 million for the three months ended June 30, 2019 compared to $200.2 million for the three months ended June 30, 2018. The decrease in revenue was attributable to lower sales volumes, partially offset by higher average selling prices for upgraded product streams. Sales volumes were 103.8 kilotons for the three months ended June 30, 2019, a decrease of 7.0 kilotons or 6.3%, as a result of constrained availability of raw materials primarily in North America, a trend that we expect to continue during 2019, and lower non-recurring raw materials sales when compared to the second quarter of 2018. The decline resulted in an 8.9% and 1.7% decrease in Performance Chemicals and Adhesives sales volumes, respectively, partially offset by a 4.8% increase in Tires sales volumes. The negative effect from changes in currency exchange rates between the periods was $5.1 million.

Cost of goods sold was $147.1 million for the three months ended June 30, 2019 compared to $139.4 million for the three months ended June 30, 2018, an increase of $7.7 million or 5.5%. The increase was driven by higher average raw material costs as a result of increased energy costs, partially offset by lower sales volumes and reflecting lower planned maintenance activities in 2019, when compared to the same period in 2018. The positive impact from changes in currency exchange rates between the periods of $4.9 million.

During the three months ended June 30, 2019, we incurred an incremental $6.9 million of direct costs associated with Hurricane Michael. Our insurance carrier also provided an additional $7.5 million of advance reimbursement under our insurance policies, which was recorded as a gain on insurance proceeds in the Condensed Consolidated Statement of Operations. The $7.5 million gain on insurance proceeds reimburses us for a portion of the direct costs we have incurred to

37

date. We continue to work with our insurance carriers to resolve all claims under our business interruption and property coverage.

For the three months ended June 30, 2019, the Chemical segment operating income was $21.2 million compared $22.6 million for the three months ended June 30, 2018.

For the three months ended June 30, 2019, the Chemical segment generated $41.9 million of Adjusted EBITDA (non-GAAP) compared to $36.9 million for the three months ended June 30, 2018. The increase in Adjusted EBITDA was primarily driven by higher margins for upgraded product streams and lower fixed costs largely due to lower planned maintenance activities in 2019, when compared to the same period in 2018, partially offset by lower sales volumes. The positive effect from changes in currency exchange rates between the periods was $0.0 million. See a reconciliation of GAAP operating income to non-GAAP Adjusted EBITDA below.

Six Months Ended June 30, 2019 compared to Six Months Ended June 30, 2018

Revenue for the Chemical segment was $392.8 million for the six months ended June 30, 2019 compared to $413.6 million for the six months ended June 30, 2018. The decrease in Chemical segment revenue was primarily attributable to lower sales volumes, partially offset by higher average selling prices for upgraded product streams. Sales volumes were 207.5 kilotons for the six months ended June 30, 2019, a decrease of 19.2 kilotons or 8.5%, as a result of constrained availability of raw materials primarily in North America, a trend which we expect to continue during 2019, and lower non-recurring raw materials sales when compared to the six months ended June 30, 2018 and lower operating rates during the six months ended June 30, 2019 at our Panama City facility due to the impacts of Hurricane Michael. As a result, Performance Chemicals and Adhesives sales volumes decreased 11.9% and 1.6%, respectively, partially offset by an increase of 2.1% in Tires sales volumes. The negative effect from changes in currency exchange rates between the periods was $12.5 million.

Cost of goods sold was $289.3 million for the six months ended June 30, 2019 compared to $287.1 million for the six months ended June 30, 2018, an increase of $2.3 million or 0.8%. The increase was driven by higher average raw material costs as a result of increased energy costs, partially offset by lower sales volumes, and reflecting lower planned maintenance activities in 2019, when compared to the same period in 2018. The positive impact from changes in currency exchange rates between the periods was $11.4 million.

During the six months ended June 30, 2019, we estimate the margin associated with lost sales due to Hurricane Michael to be $5.9 million, and we incurred an incremental $12.8 million of direct costs as we continued to ramp production back to operating capacity. Our insurance carrier provided an additional $17.5 million of advance reimbursement under our insurance policies. The $18.6 million gain on insurance, recorded as a gain on insurance proceeds in the Condensed Consolidated Statement of Operations (including $1.1 million of proceeds received during the fourth quarter of 2018, but which was deferred at that time as unearned until realizable, during the first quarter of 2019) fully offsets the lost margin in the first quarter of 2019 and reimburses us for a portion of the direct costs we have incurred to date. We continue to work with our insurance carriers to resolve all claims under our business interruption and property coverage.

For the six months ended June 30, 2019, the Chemical segment operating income was $47.1 million compared to $51.9 million for the six months ended June 30, 2018.

For the six months ended June 30, 2019, the Chemical segment generated $83.2 million of Adjusted EBITDA (non-GAAP) compared to $80.8 million for the six months ended June 30, 2018. The 2.9% increase in Adjusted EBITDA was primarily driven by higher margins for upgraded product streams and lower fixed costs largely due to lower planned maintenance activities in 2019, when compared to the same period in 2018, partially offset by lower sales volumes. The negative effect from changes in currency exchange rates between the periods was $0.4 million. See a reconciliation of GAAP operating income to non-GAAP Adjusted EBITDA below.

NON-GAAP FINANCIAL MEASURES

EBITDA, Adjusted EBITDA, and Adjusted Diluted Earnings (Loss) Per Share

We consider EBITDA, Adjusted EBITDA, and Adjusted Diluted Earnings (Loss) Per Share to be important supplemental measures of our performance and believe they are frequently used by investors, securities analysts, and other interested parties in the evaluation of our performance and/or that of other companies in our industry, including period-to-period comparisons. Further, management uses these measures to evaluate operating performance, and our incentive compensation plan bases incentive compensation payments on our Adjusted EBITDA performance and attainment of net debt reduction, along with other factors. EBITDA, Adjusted EBITDA, and Adjusted Diluted Earnings (Loss) Per Share have limitations as analytical tools and in some cases can vary substantially from other measures of our performance. You should not consider any of them in isolation, or as substitutes for analysis of our results under GAAP.

____________________________________________________ 

(1) The majority of our consolidated inventory is measured using the FIFO basis of accounting. As part of our pricing strategy, we measure our business performance using the estimated current replacement cost (“ECRC”) of our inventory and cost of goods sold. Our ECRC is based on our current expectation of the current cost of our significant raw material inputs. ECRC is developed monthly based on actual market-based contracted rates and spot market purchase rates that are expected to occur in the period. We then adjust the value of the significant raw material inputs and their associated impact to finished goods to the current replacement cost to arrive at an ECRC value for inventory and cost of goods sold. The result of this revaluation from the GAAP carrying value creates the spread between GAAP and ECRC. We maintain our perpetual inventory in our global enterprise resource planning system, where the carrying value of our inventory is determined. With inventory valued under GAAP and ECRC, we then have the ability to report cost of goods sold and therefore Adjusted EBITDA and Adjusted Diluted Earnings (Loss) Per Share under both our GAAP convention and ECRC.

(2) On a consolidated basis, EBITDA represents net income before interest, taxes, depreciation, and amortization. On a reporting segment basis, EBITDA represents segment operating income before depreciation and amortization, loss on extinguishment of debt, and earnings of unconsolidated joint venture. Limitations for EBITDA as an analytical tool include the following:

• EBITDA does not reflect the significant interest expense on our debt;

• EBITDA does not reflect the significant depreciation and amortization expense associated with our long-lived assets;

• EBITDA included herein should not be used for purposes of assessing compliance or non-compliance with financial covenants under our debt agreements. The calculation of EBITDA in the debt agreements includes adjustments, such as extraordinary, non-recurring or one-time charges, proforma cost savings, certain non-cash items, turnaround costs, and other items included in the definition of EBITDA in the debt agreements; and

• other companies in our industry may calculate EBITDA differently than we do, limiting its usefulness as a comparative measure.

(3) Adjusted EBITDA is EBITDA net of the impact of the spread between the FIFO basis of accounting and ECRC and net of the impact of items we do not consider indicative of our ongoing operating performance. We explain how each adjustment is derived and why we believe it is helpful and appropriate in the reconciliation below. You are encouraged to evaluate each adjustment and the reasons we consider it appropriate for supplemental analysis. As an analytical tool, Adjusted EBITDA is subject to the limitations applicable to EBITDA described above, as well as the following limitations:

• due to volatility in raw material prices, Adjusted EBITDA may, and often does, vary substantially from EBITDA, net income, and other performance measures, including net income calculated in accordance with GAAP; and

• Adjusted EBITDA may, and often will, vary significantly from EBITDA calculations under the terms of our debt agreements and should not be used for assessing compliance or non-compliance with financial covenants under our debt agreements.

(4) Included in EBITDA, Adjusted EBITDA, and Adjusted Diluted Earnings (Loss) Per Share is $7.5 million and $18.6 million, which was recognized as a gain on insurance proceeds in the Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2019, respectively, associated with Hurricane Michael.

Because of these and other limitations, EBITDA and Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business.  

Our presentation of non-GAAP financial measures and the adjustments made therein should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items, and in the future we may incur expenses or charges similar to the adjustments made in the presentation of our non-GAAP financial measures.

We compensate for the above limitations by relying primarily on our GAAP results and using EBITDA, Adjusted EBITDA, and Adjusted Diluted Earnings (Loss) Per Share only as supplemental measures. See our financial statements included in Part I of this Form 10-Q.

Critical Accounting Policies

For a discussion of our critical accounting policies and estimates that require the use of significant estimates and judgments, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Leases. In February 2016, the FASB established Topic 842, Leases, by issuing ASU 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; and ASU 2018-11, Targeted Improvements. The new standard establishes a ROU model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019.

The new standard provides a number of optional practical expedients in transition. We elected the following practical expedients: (1) ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification, and initial direct costs; (2) the short-term lease recognition exemption for all leases that qualify; and (3) the practical expedient to not separate lease and non-lease components for all of our leases.

This standard had a material effect on our financial statements. The most significant effects relate to: (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our equipment, building, and vehicle operating leases; (2) the derecognition of existing assets and liabilities for straight line lease accounting under ASC 840 Leases; and (3) providing significant new disclosures about our leasing activities.

On adoption, we recognized additional operating liabilities of $70.9 million, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases.

LIQUIDITY AND CAPITAL RESOURCES

Kraton Corporation is a holding company without any operations or assets other than the operations of its subsidiaries. Cash flows from operations of our subsidiaries, cash on hand, and available borrowings under the Term Loan Facility and ABL Facility are our principal sources of liquidity.

As of June 30, 2019, our outstanding borrowings included (i) $362.0 million and €300.0 million (or approximately $341.6 million) under the USD Tranche and Euro Tranche, respectively, of the Term Loan Facility, (ii) $394.8 million and €290.0 million (or approximately $330.2 million as of June 30, 2019) under the 7.0% Senior Notes and 5.25% Senior Notes, respectively, and (iii) $27.0 million under our ABL Facility.

In addition, as of June 30, 2019, KFPC had NTD 3.0 billion (or approximately $95.4 million) and NTD 450.0 million (or approximately $14.5 million) of borrowings under the KFPC Loan Agreement and KFPC Revolving Facilities, respectively. The KFPC Loan Agreement matures January 17, 2020. Subject to the terms within the KFPC Loan Agreement, we expect to elect the extension provision whereby we have the option, up to six months prior to the final maturity date, to apply to the facility agent in writing for an extension of the facility period for another two years, or January 17, 2022. We anticipate approvals by the lender syndicate by end of the third quarter 2019.

On December 6, 2018, we commenced a repurchase program for up to $20.0 million of our 7.0% Senior Notes. Purchases under the program may take place from time to time in the open market and through privately negotiated transactions, including pursuant to a 10b5-1 Plan. During the six months ended June 30, 2019, we repurchased $4.3 million of our 7.0% Senior Notes. As of the date of this filing, we repurchased $5.3 million of our 7.0% Senior Notes. The repurchase program ended March 4, 2019.

See Note 7 Long-Term Debt to the consolidated financial statement included in this Quarterly Report on Form 10-Q and Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

Based upon current and anticipated levels of operations, we believe that cash flows from operations of our subsidiaries, cash on hand, and borrowings available to us will be sufficient to fund our expected financial obligations, planned capital expenditures, and anticipated liquidity requirements, including working capital requirements, our investment in the KFPC joint venture, debt payments, interest payments, benefit plan contributions, and income tax obligations.

Going forward there can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available under the Term Loan Facility and the ABL Facility or any new credit facilities or financing arrangements to fund liquidity needs and enable us to service our indebtedness. As of the date of this filing, our available borrowing capacity under the ABL was $208.2 million, with $36.0 million of outstanding borrowings. Subject to compliance with certain covenants and other conditions, we have the option to borrow up to $350.0 million of incremental term loans plus an additional amount subject to a senior secured net leverage ratio. Our available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of cash invested in interest bearing funds and operating accounts. To date, we have not experienced any losses or lack of access to our invested cash or cash equivalents; however, we cannot provide any assurance that adverse conditions in the financial markets will not impact access to our invested cash and cash equivalents.

We made contributions of $6.5 million and $6.6 million to our pension plans during the six months ended June 30, 2019 and 2018, respectively. We expect our total pension plan contributions for the year ended December 31, 2019 to be approximately $11.2 million. Our pension plan obligations are predicated on a number of factors, the primary ones being the return on our pension plan assets and the discount rate used in deriving our pension obligations. If the investment return on our pension plan assets does not meet or exceed expectations during 2019, and the discount rate decreases from the prior year, higher levels of contributions could be required in 2020 and beyond.

As of June 30, 2019, we had $57.9 million of cash and short-term investments related to foreign operations that management asserts are permanently reinvested. As a result of net operating loss carryforwards and the impact of recent tax reform, management estimates that no incremental cash tax expense would be incurred if this cash were repatriated.

In December 2017, the Tax Act was enacted and resulted in a one-time transition tax on accumulated foreign subsidiary earnings. As of June 30, 2019, the remaining long-term tax payable related to the Tax Act of $11.9 million is presented within income tax payable, on our Condensed Consolidated Balance Sheets. We will pay the transition tax in annual interest-free installments through 2025, as permitted by the Tax Act.

Operating Cash Flows

Net cash provided by operating activities totaled $36.0 million during the six months ended June 30, 2019 compared to net cash provided by operating activities of $48.1 million during the six months ended June 30, 2018. This represents a net

44

decrease in operating cash flows of $12.1 million, which was primarily driven by decreases in operating income, partially offset by a decrease in working capital. The period-over-period changes in working capital are as follows:

• $15.5 million increase in cash flows associated with lower accounts receivables, largely due to lower selling prices; and

• $13.1 million increase in cash flows associated with lower inventories of products, materials, and supplies largely due to lower raw material costs, partially offset by higher inventory levels; and

• $12.1 million increase in cash flows associated with higher other payables and accruals, primarily driven by timing of interest payments; partially offset by;

• $6.7 million decrease in cash flows associated with lower accounts payable due to lower raw material costs; and

• $9.2 million decrease in cash flows associated with other items, including other assets, other long term liabilities, and due to related parties, primarily due to timing of transactions and payments.

Investing Cash Flows

Net cash used in investing activities totaled $55.2 million for the six months ended June 30, 2019 and $46.1 million for the six months ended June 30, 2018.

Expected Capital Expenditures

We currently expect 2019 capital expenditures in aggregate will be approximately $110.0 million, which excludes capitalized interest. Included in this estimate is $55.0 million for health, safety, environmental, and security and infrastructure and maintenance projects. We also anticipate spending approximately $25.0 million primarily associated with projects to optimize the production capabilities of our manufacturing assets, to support our innovation platform, and to upgrade our information technology systems. We are evaluating certain strategic capital activities, for which we expect to fund approximately $30.0 million of capital expenditures.

Financing Cash Flows

Our consolidated capital structure as of June 30, 2019 was approximately 32.3% equity, 66.2% debt and 1.5% noncontrolling interest compared to approximately 30.9% equity, 67.7% debt and 1.4% noncontrolling interest December 31, 2018.

On December 6, 2018, we commenced a repurchase program for up to $20.0 million of our 7.0% Senior Notes. During the six months ended June 30, 2019, we repurchased $4.3 million of our 7.0% Senior Notes.

During the six months ended June 30, 2019, we increased indebtedness, excluding impacts on foreign currency, by $3.2 million, while decreasing cash on hand by approximately $22.0 million.

Share Repurchase Program. In February 2019, we announced a repurchase program for up to $50.0 million of the Company's common stock by March 2021. Repurchases may be made at management's discretion from time to time through privately-negotiated transactions, in the open market, or through broker-negotiated purchases in compliance with applicable securities law, including through a 10b5-1 Plan. The repurchase program may be suspended for periods or discontinued at any time, and the amount and timing of the repurchases are subject to a number of factors, including Kraton's stock price. During the six months ended June 30, 2019, we repurchased 152,986 shares of our common stock at an average price of $32.68 per share and a total cost of $5.0 million. We are not obligated to acquire any specific number of shares of our common stock.

Contractual Commitments

Our contractual obligations are summarized in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. See Note 7 Long-Term Debt for changes to our debt maturity schedule. There have been no other material changes to the contractual obligations disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018.

Off-Balance Sheet Arrangements

We are not involved in any material off-balance sheet arrangements as of June 30, 2019.

45

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

For quantitative and qualitative disclosures about market risk, see Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. There have been no material changes to the quantitative and qualitative disclosures about market risk disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018. See Note 8 Fair Value Measurements, Financial Instruments, and Credit Risk for further discussion.

Item 4. Controls and Procedures.

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 or 15d-15 under the Securities Exchange Act of 1934) was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. As of June 30, 2019, based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective.

Effective January 1, 2019, we implemented ASC 842, Leases. This standard had a material effect on our financial statements. The most significant effects relate to: (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our equipment, building, and vehicle operating leases; (2) the derecognition of existing assets and liabilities for straight line lease accounting under ASC 840 Leases; and (3) providing significant new disclosures about our leasing activities. We implemented changes to our processes related to lease accounting and the control activities related to leases. These included the development of new policies largely impacting lessee accounting in the new standard, training, ongoing contract review requirements, and gathering of information provided for disclosures.

There has been no other changes in our internal control over financial reporting that occurred during the three months ended June 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

46

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

We and certain of our subsidiaries, from time to time, are parties to various other legal proceedings, claims, and disputes that have arisen in the ordinary course of business. These claims may involve significant amounts, some of which would not be covered by insurance. A substantial settlement payment or judgment in excess of our accruals could have a material adverse effect on our financial position, results of operations, or cash flows. While the outcome of these proceedings cannot be predicted with certainty, we do not expect any of these existing matters, individually or in the aggregate, to have a material adverse effect upon our financial position, results of operations, or cash flows.

For more information regarding legal proceedings, including environmental matters, see Note 10 Commitments and Contingencies to the Condensed Consolidated Financial Statements.

Item 1A. Risk Factors.

Readers of this Quarterly Report on Form 10-Q should carefully consider the risks described in our other reports and filings filed with or furnished to the SEC, including our prior and subsequent reports on Forms 10-K, 10-Q and 8-K, in connection with any evaluation of our financial position, results of operations and cash flows.

The risks and uncertainties in our most recent Annual Report on Form 10-K are not the only risks that we face. Additional risks and uncertainties not presently known or those that are currently deemed immaterial may also affect our operations. Any of the risks, uncertainties, events or circumstances described therein could cause our future financial condition, results of operations or cash flows to be adversely affected. There have been no material changes from the risk factors disclosed in our most recent Annual Report on Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Share Repurchase Program. In February 2019, we announced a repurchase program for up to $50.0 million of the Company's common stock by March 2021. Repurchases may be made at management's discretion from time to time through privately-negotiated transactions, in the open market, or through broker-negotiated purchases in compliance with applicable securities law, including through a 10b5-1 Plan. The repurchase program may be suspended for periods or discontinued at any time, and the amount and timing of the repurchases are subject to a number of factors, including Kraton's stock price. During the six months ended June 30, 2019, we repurchased 152,986 shares of our common stock at an average price of $32.68 per share and a total cost of $5.0 million. We are not obligated to acquire any specific number of shares of our common stock.

The Company repurchases treasury stock that is withheld to satisfy the tax obligation of holders of restricted stock awards when they vest. Our equity incentive plans provide that the value of shares delivered to us to pay the withholding tax obligations is calculated based on the average of the high and low sales price per share of our common stock on the date when the withholding is made.

KRATON CORPORATION

RESTRICTED STOCK UNIT INDUCEMENT AWARD AGREEMENT

Upon acceptance by you through the online acceptance procedures set forth at www.etrade.com, this Restricted Stock Unit Award Inducement Agreement (this “Agreement”) is made effective as of the Grant Date (defined below) between Kraton Corporation (the “Company”) and you (the “Participant”). This Agreement evidences a grant of restricted stock units consisting of an unfunded and unsecured promise to deliver shares of the common stock, $0.01 par value, of the Company (“Common Stock”) under the Company’s 2019 Equity Inducement Plan (as amended, the “Plan”). Unless otherwise indicated, any capitalized term used but not defined herein shall have the meaning ascribed to such term in the Plan. The award granted pursuant to this Agreement is intended to comply with the inducement award exception from the New York Stock Exchange (NYSE) rules requiring shareholder approval for the issuance of equity-based compensation. The Company will take such actions as may be necessary to comply with that exception, including notification to the NYSE and disclosure of the material terms of the inducement grants in a press release.

1.    Grant of Restricted Stock Units. Pursuant to, and subject to, the terms and conditions set forth herein and in the Plan, the Company hereby grants to the Participant an award of the number of restricted stock units of the Company set forth on the Participant’s online award acceptance page at www.etrade.com, which is incorporated by reference herein (collectively, the “Restricted Stock Units”). Each Restricted Stock Unit constitutes an unfunded and unsecured promise of the Company to deliver one share of Common Stock to Participant on the vesting date subject to the terms and conditions of this Agreement. Participant’s rights with respect to the Restricted Stock Units shall be forfeitable until the Restricted Stock Units vest in accordance with Section 4. As a holder of Restricted Stock Units, the Participant has the rights of a general unsecured creditor of the Company unless and until the Restricted Stock Units are converted to shares of Common Stock upon vesting and transferred to Participant, as set forth herein. During the period prior to vesting of the Restricted Stock Units in accordance with Section 4, the Restricted Stock Units shall be bookkeeping entries only, and Participant shall have no rights to receive any shares of Common Stock hereunder. Participant shall have no voting or other rights of a stockholder of the Company with respect to the Restricted Stock Units prior to the issuance of Shares in accordance with Section 6.

2.    Grant Date. The grant date of the Restricted Stock Units (the “Grant Date”) is the date set forth on the Participant’s online award acceptance page at www.etrade.com, which is incorporated by reference herein.

3.    Incorporation of Plan. All terms, conditions and restrictions of the Plan are incorporated herein and made part hereof as if stated herein. If there is any conflict between the terms and conditions of the Plan and this Agreement, the terms and conditions of the Plan, as interpreted by the Committee, shall govern. All capitalized terms used herein that are not defined in this Agreement shall have the meanings given to such terms in the Plan.

4.    Vesting Date; Settlement. The Restricted Stock Units shall become vested as follows:

(a) One hundred percent (100%) of the Restricted Stock Units shall vest on  the first (1^st) anniversary of the Grant Date, provided that the Participant remains continuously employed by the Company through each such date; or

(b) One hundred percent (100%) of the Restricted Stock Units shall vest on the date that the Participant’s employment is terminated due to Disability or death at any time prior to the first (1^st) anniversary of the Grant Date.

Notwithstanding the foregoing:

(c) If on or before the first anniversary of a Change in Control the Participant’s employment is terminated by the Company or its affiliate without Cause, all Restricted Stock Units held by such Participant shall immediately vest as of the effective date of such termination of the Participant’semployment, subject to the Participant's execution of an effective general release and waiver of all claims against the Company, its affiliates and their respective officers and directors related to the Participant’s employment, in a form acceptable to the Company at the Participant’s termination of employment.

Upon the occurrence of vesting described above, the Company shall deliver to the Participant the shares of Common Stock via electronic book-entry issuance. If and when cash dividends or other cash distributions are paid or distributed with respect to the Common Stock while the Restricted Stock Units are outstanding, the dollar amount of such dividends or distributions with respect to the number of shares of Common Stock then underlying the Restricted Stock Units shall be reflected in a notional account maintained by the Company on your behalf. Any such cash dividends or other cash distributions shall vest and be paid in cash if and at such times as the underlying Restricted Stock Units are vested and paid.

For purposes of this Agreement, “Disability” has the meaning ascribed to it in the Company’s long-term disability plan, and “Cause” means (i) a material breach by the Participant of any of the Participant’s obligations under any written agreement with the Company or any of its affiliates, (ii) a material violation by the Participant of any of the Company’s policies, procedures, rules and regulations applicable to employees generally or to employees at your grade level, in each case, as they may be amended from time to time in the Company’s sole discretion; (iii) the failure by the Participant to reasonably and substantially perform his or her duties to the Company or its affiliates (other than as a result of physical or mental illness or injury); (iv) the Participant’s willful misconduct or gross negligence that has caused or is reasonably expected to result in material injury to the business, reputation or prospects of the Company or any of its affiliates; (v) the Participant’s fraud or misappropriation of funds; or (vi) the commission by the Participant of a felony or other serious crime involving moral turpitude; provided that if the Participant is a party to an employment agreement with the Company or its affiliate (an “Employment Agreement”) at the time of his or her termination of employment and such Employment Agreement contains a different definition of “cause” (or any derivation thereof), the definition in such Employment Agreement will control for purposes of this Agreement. “Continuously employed” (or similar) means employment with the Company measured from the most recent date of hire with the Company and disregarding any and all periods of employment prior to such date.

If a Participant is terminated without Cause and, within the twelve (12)-month period subsequent to such termination of employment, the Company determines in good faith that the Participant’s employment could have been terminated for Cause, subject to anything to the contrary that may be contained in the Participant’s Employment Agreement at the time of his or her termination of employment, the Participant’s employment will, at the election of the Company, be deemed to have been terminated for Cause, effective as of the date the events giving rise to Cause occurred.

5.    Forfeiture; Restrictions. Subject to the provisions of the Plan and Section 4 of this Agreement, with respect to the Restricted Stock Units that have not become vested on the date the Participant’s employment is terminated, the award of Restricted Stock Units shall expire and such unvested Restricted Stock Units shall immediately be forfeited on such date. Participant shall not sell, transfer, pledge, assign, alienate, hypothecate, or otherwise encumber or dispose of the Restricted Stock Units other than by will or the laws of descent and distribution.

6.    Delivery of Shares; Compliance with Securities Laws. Upon the vesting of any Restricted Stock Units granted hereunder, the Company shall direct its transfer agent to record by electronic book-entry in Participant’s name a number of unrestricted shares of Common Stock equal to the whole number of Restricted Stock Units that become vested hereunder. Nothing herein shall obligate the Company to register the Restricted Stock Units pursuant to any applicable securities law or to take any other affirmative action in order to cause the issuance or transfer of the Restricted Stock Units to comply with any law or regulation of any governmental authority. The Company shall not be required to issue any shares of Common Stock prior to: (a) the obtaining of any approval from any governmental agency which the Company determinesto be necessary or advisable; and (b) the Participant’s payment to the Company of any federal, state or local tax or other withholding owed by Participant as a result of vesting of the Restricted Stock Units.

7.    Delays or Omissions. No delay or omission to exercise any right, power, or remedy accruing to any party hereto upon any breach or default of any party under this Agreement, shall impair any such right, power or remedy of such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party or any provisions or conditions of this Agreement, shall be in writing and shall be effective only to the extent specifically set forth in such writing.

8.    Integration. This Agreement and the Plan contain the entire understanding of the parties with respect to its subject matter. There are no restrictions, agreements, promises, representations, warranties, covenants or undertakings with respect to the subject matter hereof other than those expressly set forth herein and the Plan.

Accounting Policies [Abstract]

General

General

Description of our Business. We are a leading global specialty chemicals company that manufactures styrenic block copolymers (“SBCs”), specialty polymers, and high-value performance products primarily derived from pine wood pulping co-products.

SBCs are highly-engineered synthetic elastomers, which we originally invented and commercialized. Our SBCs enhance the performance of numerous products by imparting greater flexibility, resilience, strength, durability, and processability, and are used in a wide range of applications, including adhesives, coatings, consumer and personal care products, sealants, lubricants, medical, packaging, automotive, and paving and roofing products. We manufacture and sell isoprene rubber and isoprene rubber latex, which are non-SBC products primarily used in applications such as medical products, personal care, adhesives, tackifiers, paints, and coatings.

We refine and further upgrade crude tall oil and crude sulfate turpentine, into value-added specialty chemicals. These pine-based specialty products are sold into adhesive and tire markets, and we produce and sell a broad range of performance chemicals (which we formerly referred to as chemical intermediates) into markets that include fuel additives, oilfield chemicals, coatings, metalworking fluids and lubricants, inks, flavors and fragrances, and mining.

Basis of Presentation. The accompanying unaudited Condensed Consolidated Financial Statements presented in this report are for us and our consolidated subsidiaries, each of which is a wholly-owned subsidiary, except our 50% investment in our joint venture, Kraton Formosa Polymers Corporation (“KFPC”), located in Mailiao, Taiwan. KFPC is a variable interest entity for which we have determined that we are the primary beneficiary and, therefore, have consolidated into our financial statements. Our 50% investment in our joint venture located in Kashima, Japan, is accounted for under the equity method of accounting. All significant intercompany transactions have been eliminated. These interim financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly our results of operations and financial position. Amounts reported in our Condensed Consolidated Statements of Operations are not necessarily indicative of amounts expected for the respective annual periods or any other interim period, in particular due to the effect of seasonal changes and weather conditions that typically affect our sales into paving, roadmarking, roofing, and construction applications. In particular, sales volumes into these applications are generally higher in the second and third quarter of the calendar year as warm and dry weather is more conducive to paving and roofing activity.

Reclassifications. Certain amounts reported in the condensed consolidated financial statements and notes to the consolidated financial statements for the prior periods have been reclassified to conform to the current reporting presentation.

Significant Accounting Policies. Our significant accounting policies have been disclosed in Note 1 Description of Business, Basis of Presentation, and Significant Accounting Policies in our most recent Annual Report on Form 10-K. Except for the changes below, the Company has consistently applied the accounting policies presented in the Condensed Consolidated Financial Statements.

Leases. See Note 2 New Accounting Pronouncements, for the impact of ASC 842, Leases, adopted in the current period.

There have been no other changes to the accounting policies, which are disclosed in our most recent Annual Report on Form 10-K. The accompanying unaudited Condensed Consolidated Financial Statements we present in this report have been prepared in accordance with our policies.

Use of Estimates. The preparation of these Condensed Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant items subject to such estimates and assumptions include:

• the useful lives of long-lived assets;

• estimates of fair value for assets acquired and liabilities assumed in business combinations;

• allowances for doubtful accounts and sales returns;

• the valuation of derivatives, deferred tax assets, property, plant and equipment, intangible assets, inventory, investments, and share-based compensation; and

• liabilities for employee benefit obligations, environmental matters, asset retirement obligations, income tax uncertainties, and other contingencies.

Income Tax in Interim Periods. We conduct operations in separate legal entities in different jurisdictions. As a result, income tax amounts are reflected in these Condensed Consolidated Financial Statements for each of those jurisdictions. Tax laws and tax rates vary substantially in these jurisdictions and are subject to change based on the political and economic climate in those countries. We file our tax returns in accordance with our interpretations of each jurisdiction’s tax laws. We record our tax provision or benefit on an interim basis using the estimated annual effective tax rate. This rate is applied to the current period ordinary income or loss to determine the income tax provision or benefit allocated to the interim period.

Losses from jurisdictions for which no benefit can be realized and the income tax effects of unusual and infrequent items are excluded from the estimated annual effective tax rate. Valuation allowances are provided against the future tax benefits that arise from the losses in jurisdictions for which there is uncertainty that they may be realized. The effects of unusual and infrequent items are recognized in the impacted interim period as discrete items.

The estimated annual effective tax rate may be significantly affected by nondeductible expenses and by our projected earnings mix by tax jurisdiction. Adjustments to the estimated annual effective income tax rate are recognized in the period during which such estimates are revised.

We have established valuation allowances against a variety of deferred tax assets, including net operating loss carryforwards, foreign tax credits and other income tax credits. Valuation allowances take into consideration our expected ability to realize these deferred tax assets and reduce the value of such assets to the amount that is deemed more likely than not to be recoverable. Our ability to realize these deferred tax assets is dependent on achieving our forecast of future taxable operating income over an extended period of time. We review our forecast in relation to actual results and expected trends on a quarterly basis. If we fail to achieve our operating income targets, we may change our assessment regarding the recoverability of our net deferred tax assets and such change could result in a valuation allowance being recorded against some or all of our net deferred tax assets. A change in our valuation allowance would impact our income tax benefit (expense) and our stockholders’ equity and could have a significant impact on our results of operations or financial condition in future periods.

Accounting Changes and Error Corrections [Abstract]

New Accounting Pronouncements

New Accounting Pronouncements

Accounting Standards Adopted in the Current Period

We have implemented all new accounting pronouncements that are in effect and that management believes would materially affect our financial statements.

In February 2016, the FASB established Topic 842, Leases, by issuing ASU 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; and ASU 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (“ROU”) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application. The new standard provides a number of optional practical expedients in transition. We elected the following practical expedients: (1) ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification, and initial direct costs; (2) the short-term lease recognition exemption for all leases that qualify; and (3) the practical expedient to not separate lease and non-lease components for all of our leases.

This standard had a material effect on our financial statements. The most significant effects relate to: (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our equipment, building, and vehicle operating leases; (2) the derecognition of existing assets and liabilities for straight line lease accounting under ASC 840 Leases; and (3) providing significant new disclosures about our leasing activities. On adoption, we recognized additional operating liabilities of $70.9 million, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objective of this ASU is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This standard is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2017-12 was completed during 2018 and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2017-12 effective January 1, 2019.

In October 2018, the FASB issued 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. This standard is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2018-16 was completed during 2018, and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2018-16 effective January 1, 2019.

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2018-02 was completed during 2018, and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2018-02 effective January 1, 2019.

New Accounting Standards to be Adopted in Future Periods

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and early adoption is permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017. Our evaluation of this standard is currently ongoing, and we expect to adopt ASU 2017-04 effective on January 1, 2020.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This standard is effective for fiscal years beginning after December 15, 2019, and early adoption is permitted for any interim period after issuance of the ASU. Our evaluation of this standard is currently ongoing, and we expect to adopt ASU 2018-18 effective on January 1, 2020.

Revenue Recognition

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs at a point in time when the transfer of risk and title to the product transfers to the customer. Our standard terms of delivery are included in our contracts of sale, order confirmation documents, and invoices. As such, all revenue is considered revenue recognized from contracts with customers, and we do not have other sources of revenue. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Revenue is recognized net of sales tax, value-added taxes, and other taxes. Shipping and other transportation costs charged to customers are recorded in both revenue and cost of goods sold. We do not have any material significant payment terms as payment is received at or shortly after the point of sale. Certain customers may receive cash-based incentives (including rebates, price supports, and sales commission), which are accounted for as variable consideration. We estimate rebates and price supports based on the expected amount to be provided to customers and reduce revenues recognized once the performance obligation has been met. Sales commissions are recorded as an increase in cost of goods sold once the performance obligation has been met. We do not expect to have significant changes in our estimates for variable considerations.

We have deferred revenue of $13.2 million related to contractual commitments with customers for which the performance obligation will be satisfied over time, which will range from one to ten years. The revenue associated with these performance obligations is recognized as the obligation is satisfied, which occurs as a volume based metric over time when the transfer of risk and title of finished products transfer to the customer.

Occasionally, we enter into bill-and-hold contracts, where we invoice the customer for products even though we retain possession of the products until a point in time in the future when the products will be shipped to the customer. In these contracts, the primary performance obligation is satisfied at a point in time when the product is segregated from our general inventory, it is ready for shipment to customer, and we do not have the ability to use the product or direct it to another customer. Additionally, we have a secondary performance obligation related to custodial costs, including storage and freight, which is satisfied over time once the product has been delivered to the customer. During the three and six months ended June 30, 2019, we recognized $0.3 million and $6.0 million of revenue related to these arrangements, respectively. During the three and six months ended June 30, 2018, we recognized $0.7 million and $4.5 million of revenue related to these arrangements, respectively.

We disaggregate our revenue by segment product lines, which is how we market our products and review results of operations. The following tables disaggregate our segment revenue by major product lines:

Share-Based Compensation

Share-Based Compensation

We account for share-based awards under the provisions of ASC 718, Compensation—Stock Compensation. Accordingly, share-based compensation cost is measured at the grant date based on the fair value of the award, and we expense these costs using the straight-line method over the requisite service period, generally three years. Share-based compensation expense was $2.2 million for both the three months ended June 30, 2019 and 2018, respectively, and $5.5 million and $5.1 million for the six months ended June 30, 2019 and 2018, respectively.

Earnings Per Share [Abstract]

Earnings Per Share ("EPS")

Earnings Per Share (“EPS”)

Basic EPS is computed by dividing net income attributable to Kraton by the weighted-average number of shares outstanding excluding non-vested restricted stock awards during the period. Diluted EPS is computed by dividing net income attributable to Kraton by the diluted weighted-average number of shares outstanding during the period and, accordingly, reflects the potential dilution that could occur if securities or other agreements to issue common stock, such as stock options, were exercised, settled, or converted into common stock and were dilutive. The diluted weighted-average number of shares used in our diluted EPS calculation is determined using the treasury stock method.

The calculations of basic and diluted EPS are as follows:

Share Repurchase Program. In February 2019, we announced a repurchase program for up to $50.0 million of the Company's common stock by March 2021. Repurchases may be made at management's discretion from time to time through privately-negotiated transactions, in the open market, or through broker-negotiated purchases in compliance with applicable securities law, including through a 10b5-1 Plan. The repurchase program may be suspended for periods or discontinued at any time, and the amount and timing of the repurchases are subject to a number of factors, including Kraton's stock price. During the six months ended June 30, 2019, we repurchased 152,986 shares of our common stock at an average price of $32.68 per share and a total cost of $5.0 million. We are not obligated to acquire any specific number of shares of our common stock.

Our Term Loan Facility will mature on March 8, 2025. For a summary of additional terms of the Term Loan Facility, see Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

As of the date of this filing, the effective interest rate for the USD Tranche is 4.29% and the effective interest rate for the Euro Tranche is 2.75%. The Term Loan Facility contains a number of customary affirmative and negative covenants, and we were in compliance with those covenants as of the date of this filing.

7.0% Senior Notes due 2025. Kraton Polymers LLC and its wholly-owned financing subsidiary Kraton Polymers Capital Corporation issued $400.0 million aggregate principal amount of 7.0% Senior Notes due 2025 (the “7.0% Senior Notes”) in March 2017, which mature on April 15, 2025. The 7.0% Senior Notes are general unsecured, senior obligations, and are unconditionally guaranteed on a senior unsecured basis by each of Kraton Corporation and certain of our wholly-owned domestic subsidiaries. We pay interest on the senior notes at 7.0% per annum, semi-annually in arrears on January 15 and July 15 of each year.

On December 6, 2018, we commenced a repurchase program for up to $20.0 million of our 7.0% Senior Notes. Purchases under the program took place from time to time in the open market and through privately negotiated transactions, including pursuant to a 10b5-1 Plan. During the six months ended June 30, 2019, we repurchased $4.3 million of our 7.0% Senior Notes. We recorded a $0.2 million gain on extinguishment of debt during the six months ended June 30, 2019, which includes a write off of $0.1 million related to previously capitalized deferred financing costs. The repurchase program ended March 4, 2019.

5.25% Senior Notes due 2026. Kraton Polymers LLC and its wholly-owned financing subsidiary Kraton Polymers Capital Corporation issued €290.0 million (or approximately $330.2 million as of June 30, 2019) aggregate principal amount of 5.25% Senior Notes due 2026 (the “5.25% Senior Notes”) in May 2018, which mature on May 15, 2026. The 5.25% Senior Notes are general unsecured, senior obligations, and are unconditionally guaranteed on a senior unsecured basis by each of Kraton Corporation and certain of our wholly-owned domestic subsidiaries. We pay interest on the senior notes at 5.25% per annum, semi-annually in arrears on May 15 and November 15 of each year.

ABL Facility. Our asset-based revolving credit facility provides financing of up to $250.0 million (the “ABL Facility”). The ABL Facility also provides that we have the right at any time to request up to $100.0 million of additional commitments, provided that we satisfy certain additional conditions. Our outstanding borrowings under the ABL facility were $27.0 million as of June 30, 2019. The ABL Facility matures on January 6, 2021.

Borrowing availability under the ABL Facility is subject to borrowing base limitations based on the level of receivables and inventory available for security. Revolver commitments under the ABL Facility consist of U.S. and Dutch revolving credit facility commitments, and the terms of the ABL Facility require the U.S. revolver commitment comprises at least 60.0% of the commitments under the ABL Facility. The ABL Facility contains a number of customary affirmative and negative covenants, and we were in compliance with those covenants as of the date of this filing. For a summary of additional terms of the ABL Facility, see Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

KFPC Loan Agreement. As of June 30, 2019, NTD 3.0 billion (or approximately $95.4 million) was drawn on KFPC's syndicated loan agreement (the “KFPC Loan Agreement”). For the three and six months ended June 30, 2019, our effective interest rate for borrowings on the KFPC Loan Agreement was 1.8%. The KFPC Loan Agreement contains certain financial covenants that change during the term of the KFPC Loan Agreement. KFPC was in compliance with certain covenants as of the date of this filing. Additionally, due to a waiver received from the majority of lenders, we are no longer subject to the remaining 2019 financial covenants. In each case, these covenants are calculated and tested on an annual basis at December 31^st each year.

The KFPC Loan Agreement matures January 17, 2020. Subject to the terms within the KFPC Loan Agreement, we expect to elect the extension provision whereby we have the option, up to six months prior to the final maturity date, to apply to the facility agent in writing for an extension of the facility period for another two years, or January 17, 2022. We anticipate approvals by the lender syndicate by end of the third quarter 2019. For a summary of additional terms of the KFPC Loan Agreement, see Note 9 Long-Term Debt to the consolidated financial statements set forth in our most recently filed Annual Report on Form 10-K.

KFPC Revolving Facilities. KFPC also has five revolving credit facilities (the “KFPC Revolving Facilities”) to provide funding for working capital requirements and/or general corporate purposes, which allow for total borrowings of up to NTD 2.2 billion (or approximately $69.2 million). All of the KFPC Revolving Facilities are subject to variable interest rates. As of June 30, 2019, NTD 450.0 million (or approximately $14.5 million) was drawn on the KFPC Revolving Facilities.

Debt Issuance Costs. We had net debt issuance cost of $27.0 million as of June 30, 2019, of which $1.8 million related to the ABL Facility which is recorded as an asset (of which $1.2 million was included in other current assets) and $25.3 million is recorded as a reduction to long-term debt. We amortized $1.2 million and $1.4 million for the three months ended June 30, 2019, and 2018, respectively, and $2.3 million and $3.3 million during the six months ended June 30, 2019 and 2018, respectively.

Fair Value Measurements, Financial Instruments and Credit Risk

Fair Value Measurements, Financial Instruments, and Credit Risk

ASC 820, Fair Value Measurements and Disclosures defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value measurements. ASC 820 requires entities to, among other things, maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

ASC 820 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 our market assumptions.

In accordance with ASC 820, these two types of inputs have created the following fair value hierarchy:

• Level 1—Inputs that are quoted prices (unadjusted) for identical assets or liabilities in active markets;

• Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability, including:

• Quoted prices for similar assets or liabilities in active markets;

• Quoted prices for identical or similar assets or liabilities in markets that are not active;

• Inputs other than quoted prices that are observable for the asset or liability; and

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means; and

• Level 3—Inputs that are unobservable and reflect our assumptions used in pricing the asset or liability based on the best information available under the circumstances (e.g., internally derived assumptions surrounding the timing and amount of expected cash flows).

Recurring Fair Value Measurements. The following tables set forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2019 and December 31, 2018. These financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which judgment may affect the valuation of their fair value and placement within the fair value hierarchy levels. As of June 30, 2019 and December 31, 2018, the Company has no assets or liabilities utilizing significant unobservable inputs (or Level 3) to derive its estimated fair values.

Financial Instruments    

Interest Rate Swap Agreements. Periodically, we enter into interest rate swap agreements to hedge or otherwise protect against interest rate fluctuation on a portion of our variable rate debt. These interest rate swap agreements are designated as cash flow hedges on our exposure to the variability of future cash flows.

In an effort to convert a substantial portion of our future interest payments pursuant to the USD Tranche to a fixed interest rate, in February and March 2016 we entered into several interest rate swap agreements with an aggregate notional value of $925.4 million, effective dates of January 3, 2017 and maturity dates of December 31, 2020. In May 2018 we entered into an interest rate swap agreement with a notional value of $90.0 million, effective date of June 4, 2018 and maturity date of December 31, 2018. We exited out of $715.4 million of our interest rate swaps as of December 31, 2018, including the expiration of the notional value of $90.0 million interest rate swap agreement entered into in May 2018. As a result, at June 30, 2019, the total notional value of our interest rate swaps was $300.0 million, which effectively hedges the outstanding USD Tranche, fixing LIBOR at 1.608%. We recorded an unrealized loss of $2.6 million and an unrealized gain of $0.9 million for the three months ended June 30, 2019 and 2018, respectively, and an unrealized loss of $4.3 million and an unrealized gain of $4.6 million during the six months ended June 30, 2019 and 2018, respectively, in other comprehensive income (loss) related to the effective portion of these interest rate swap agreements. In addition, we reclassified out of other comprehensive income (loss) the settlement of a portion of our interest rate swap that amounted to a $2.6 million gain for the six months ended June 30, 2018.

Foreign Currency Hedges. Periodically, we enter into foreign currency agreements to hedge or otherwise protect against fluctuations in foreign currency exchange rates. These agreements do not qualify for hedge accounting, and gains/losses resulting from both the up-front premiums and/or settlement of the hedges at expiration of the agreements are recognized in the period in which they are incurred. We settled these hedges and recorded a gain of $0.3 million and a loss of $0.2 million for the three months ended June 30, 2019 and 2018, respectively, and a loss of $1.9 million and $0.2 million for the six months ended June 30, 2019 and 2018, respectively, which are recorded in cost of goods sold in the Condensed Consolidated Statements of Operations. These contracts are structured such that these gains/losses from the mark-to-market impact of the hedging instruments materially offset the underlying foreign currency exchange gains/losses to reduce the overall impact of foreign currency exchange movements throughout the period.

Net Investment Hedge. During the year ended December 31, 2018, we designated €290.0 million of euro-denominated borrowing as a hedge against a portion of our net investment in the Company's European operations. The mark to market of this instrument was a gain of $1.3 million and $3.5 million for the six months ended June 30, 2019 and 2018, respectively, which is recorded within accumulated other comprehensive income (loss) in the Condensed Consolidated Balance Sheets.

Credit Risk

The use of derivatives creates exposure to credit risk in the event that the counterparties to these instruments fail to perform their obligations under the contracts, which we seek to minimize by limiting our counterparties to major financial institutions with acceptable credit ratings and by monitoring the total value of positions with individual counterparties.

We analyze our counterparties’ financial condition prior to extending credit, and we establish credit limits and monitor the appropriateness of those limits on an ongoing basis. We also obtain cash, letters of credit, or other acceptable forms of security from customers to provide credit support, where appropriate, based on our financial analysis of the customer and the contractual terms and conditions applicable to each transaction.

Income Taxes

Income Taxes

Our income tax provision was a benefit of $6.8 million and $1.8 million for the three months ended June 30, 2019 and 2018, respectively, and a benefit of $4.2 million and an expense of $0.4 million for the six months ended June 30, 2019 and 2018, respectively. Our effective tax rate was 18.7% and 11.6% for the three months ended June 30, 2019 and 2018, respectively, and 7.9% and 4.9% for the six months ended June 30, 2019 and 2018, respectively. During the six months ended June 30, 2019, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various foreign jurisdictions, the tax impact of certain permanent items, and our uncertain tax positions, particularly the release from the closing of the U.S tax audit. During the six months ended June 30, 2018, our effective tax rate differed from the U.S. corporate statutory tax rate of 21.0% primarily due to the mix of our pretax income or loss generated in various foreign jurisdictions and our uncertain tax positions.

The provision for income taxes differs from the amount computed by applying the U.S. corporate statutory income tax rate to income (loss) before income taxes for the reasons set forth below.

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Income taxes at the statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State taxes, net of federal benefit	1.3		1.3		1.3		1.8
Foreign tax rate differential	(9.2	)	8.5		(6.3	)	(50.2	)
Permanent differences	7.3		(11.8	)	2.1		(1.7	)

Other	—		—		—		—
Effective tax rate	(18.7	)%	11.6	%	(7.9	)%	4.9	%

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. We consider all available material evidence, both positive and negative, in assessing the appropriateness of a valuation allowance for our deferred tax assets. In determining whether a valuation allowance is required during the period, we evaluate primarily (a) cumulative earnings and losses in recent years, (b) historical taxable income or losses as it relates to our ability to utilize operating loss and tax credit carryforwards within the expiration period, (c) trends indicating earnings or losses expected in future years along with our ability in prior years to reasonably project these future trends or operating results, (d) length of the carryback and carryforward period, and (e) prudent and feasible tax-planning strategies, particularly related to operational changes and the impact on the timing or taxability of relative amounts.

As of June 30, 2019 and December 31, 2018, we recorded a valuation allowance of $42.1 million and $42.5 million, respectively, against our net operating loss carryforwards and other deferred tax assets. We decreased our valuation allowances by $0.3 million and $0.4 million for the three and six months ended June 30, 2019, respectively, primarily related to current period utilization of net operating loss carryforwards in certain jurisdictions. We increased our valuation allowances by $0.6 million and $0.4 million for the three and six months ended June 30, 2018, respectively, primarily related to current period net operating losses in the U.S.

For the period ending June 30, 2019, a portion of the unremitted foreign earnings are permanently reinvested in the corresponding country of origin. Accordingly, we have not provided deferred taxes for the differences between the book basis and underlying tax basis in those subsidiaries or on the foreign currency translation adjustment amounts related to such operations.

We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. For our U.S. federal income tax returns, the statute of limitations has expired through the tax year ended December 31, 2003. As a result of net operating loss carryforwards from 2004, the statute remains open for all years subsequent to 2003. In addition, open tax years for state and foreign jurisdictions remain subject to examination.

We recognize the tax impact of certain tax positions only when it is more likely than not those such positions are sustainable. The taxes are recorded in accordance with ASC 740-10, Accounting for Uncertainty in Income Taxes, which prescribes the minimum recognition threshold.

As of June 30, 2019 and December 31, 2018, we had total unrecognized tax benefits of $16.1 million and $29.6 million, respectively, related to uncertain tax positions, all of which, if recognized, would impact our effective tax rate. During the three and six months ended June 30, 2019, we had a decrease of $13.9 million and $13.5 million, respectively, primarily related to the closing of the U.S. tax audit for the pre-acquisition tax return filing. During the three and six months ended June 30, 2018, we had an increase of $0.1 million and $0.9 million, respectively, primarily related to our uncertain tax positions in the U.S. and Europe. We recorded interest and penalties related to unrecognized tax benefits within the provision for income taxes. For the year ending December 31, 2019, we expect to release $19.7 million in reserves, of which $14.0 million was released during the three months ended June 30, 2019 as a result of the closing of certain U.S. tax audits.

The Tax Cuts and Jobs Act enacted on December 22, 2017 (the “Tax Act”) introduced significant changes to U.S. income tax law. Effective 2018, the Tax Act reduced the U.S. statutory tax rate from 35.0% to 21.0% and created new taxes on certain foreign-sourced earnings and certain related-party payments.

One-time transition tax

The Tax Act required us to pay U.S. income taxes on accumulated foreign subsidiary earnings not previously subject to U.S. income tax at a rate of 15.5% to the extent of foreign cash and certain other net current assets and 8.0% on the remaining earnings. Related to the 2017 tax year, we recorded a $15.7 million one-time transitional tax liability. Any legislative changes, including the final Section 965 transition tax regulations issued on January 15, 2019, whose impact is currently being assessed due to the complexity and interdependency of the legislative provisions, as well as any other new or proposed Treasury regulations, which have yet to be issued, may result in additional income tax impacts which could be material in the period any such changes are enacted.

Deferred tax effects

Due to the change in the statutory tax rate from the Tax Act, we remeasured our deferred taxes as of December 31, 2017 to reflect the reduced rate that will apply in future periods when these deferred taxes are settled or realized. We recognized a deferred tax benefit of $95.0 million, of which $68.9 million relates to the reduction of the U.S. statutory tax rate from 35.0% to 21.0% for years after 2017 and the remaining relates to changes in our investments in foreign subsidiaries. For the period ending December 31, 2018, we completed our analysis based on legislative updates relating to the Tax Act and made no adjustments to the provisional amounts previously recorded.

(a) Lease Commitments - accounted for under ASC 842 Leases

Substantially all our operating lease ROU assets and operating lease liability represents leases, with a term greater than one year, for railcars, office space, and equipment used to conduct our operations. We currently have no finance leases. These leases were discounted using a rate of 3.125%, which is based on a weighted average borrowing rate of specific debt. Non-variable lease costs include the amortization of the asset recorded on a straight-line basis. Variable lease components are non-index based payments based on performance or usage of the underlying asset. We have no material lessor or sublease income.

(b) Legal Proceedings

We received an initial notice from the tax authorities in Brazil during the fourth quarter of 2012 in connection with tax credits that were generated from the purchase of certain goods which were subsequently applied by us against taxes owed. The tax authorities are currently assessing R$9.6 million, or approximately $2.5 million. We have appealed the assertion by the tax authorities in Brazil that the goods purchased were not eligible to earn the credits. While the outcome of this proceeding cannot be predicted with certainty, we do not expect this matter to have a material adverse effect upon our financial position, results of operations or cash flows.

We and certain of our subsidiaries, from time to time, are parties to various other legal proceedings, claims and disputes that have arisen in the ordinary course of business. These claims may involve significant amounts, some of which would not be covered by insurance. A substantial settlement payment or judgment in excess of our accruals could have a material adverse effect on our financial position, results of operations or cash flows. While the outcome of these proceedings cannot be predicted with certainty, we do not expect any of these existing matters, individually or in the aggregate, to have a material adverse effect upon our financial position, results of operations or cash flows.

(c) Asset Retirement Obligations.

The changes in the aggregate carrying amount of our asset retirement obligations are as follows:

During the year ended December 31, 2018, we amended the post-retirement benefits plan for post-65 retirees to provide an annual subsidy based on years of service. The annual subsidy replaces a company-sponsored medical plan. This plan modification resulted in a $13.1 million reduction in pension and other post-retirement liabilities during the year ended December 31, 2018.

The components of net periodic benefit costs other than the service cost component are included in Other expense on our Condensed Consolidated Statements of Operations.

Segment Reporting [Abstract]

Industry Segment and Foreign Operations

Industry Segments and Foreign Operations

Our operations are managed through two operating segments: (i) Polymer segment; and (ii) Chemical segment. In accordance with the provisions of ASC 280, Segment Reporting, our chief operating decision maker has been identified as our President and Chief Executive Officer, who reviews operating results to make decisions about allocating resources and assessing performance for the entire company.

• Polymer Segment is comprised of our SBCs and other engineered polymers business.

• Chemical Segment is comprised of our pine-based specialty products business.

Our chief operating decision maker uses operating income (loss) as the primary measure of each segment's operating results in order to allocate resources and in assessing the company's performance. In accordance with ASC 280, Segment Reporting, we have presented operating income for each segment. The following table summarizes our operating results by segment. We do not have sales between segments.

Impact of Hurricane Michael

During the six months ended June 30, 2019, we incurred an incremental $12.8 million of direct costs as we continued to ramp production back to operating capacity. Our insurance carrier provided an additional $17.5 million of advance reimbursement under our insurance policies, recorded as a gain on insurance proceeds in the Condensed Consolidated Statement of Operations (including $1.1 million of proceeds received during the fourth quarter of 2018, but which was deferred at that time as unearned until realizable, during the first quarter of 2019). The $18.6 million gain on insurance fully offsets the lost margin in the first quarter of 2019 and reimburses us for a portion of the direct costs we have incurred to date. We currently estimate the replacement cost associated with damaged equipment to be in a range of $9.0 million to $11.0 million. We have spent $5.6 million as of June 30, 2019. We continue to work with our insurance carriers to resolve all claims under our business interruption and property coverage.

We own a 50% equity investment in an SBC manufacturing joint venture in Kashima, Japan. Our outstanding payables were $16.5 million and $20.1 million as of June 30, 2019 and December 31, 2018, respectively, which were recorded in “Due to related party” liability on the Condensed Consolidated Balance Sheets. Our total purchases from the joint venture were $8.2 million and $7.2 million for the three months ended June 30, 2019 and 2018, respectively, and $16.4 million and $16.3 million for the six months ended June 30, 2019 and 2018, respectively.

We own a 50% variable interest in KFPC, an HSBC manufacturing joint venture in Mailiao, Taiwan. The KFPC joint venture is fully consolidated in our financial statements, and our joint venture partner, Formosa Petrochemical Corporation (“FPCC”), is a related party affiliate. Under the terms of the joint venture agreement, FPCC is to provide certain site services and raw materials to KFPC. Additionally, we purchase certain raw materials from FPCC for our other manufacturing locations. Our outstanding payables were $0.7 million and $0.8 million as of June 30, 2019 and December 31, 2018, respectively, which were recorded in “Due to related party” liability on the Condensed Consolidated Balance Sheets. Our total purchases from this joint venture were $13.6 million and $7.4 million for the three months ended June 30, 2019 and 2018, respectively, and $25.4 million and $13.1 million for the six months ended June 30, 2019 and 2018, respectively.

Noncontrolling Interest [Abstract]

Variable Interest Entity

Variable Interest Entity

We hold a variable interest in a joint venture with FPCC to own and operate a 30 kiloton HSBC plant at FPCC’s petrochemical site in Mailiao, Taiwan. Included in the below assets and liabilities is a land lease with FPCC to support our operations at the HSBC plant. Kraton and FPCC are each 50% owners of the joint venture company, KFPC. Under the provisions of an offtake agreement with KFPC, we have exclusive rights to purchase all production from KFPC. Additionally, following a ramp-up period, the agreement requires us to purchase a minimum of 80% of the plant production capacity each year at a defined fixed margin. This offtake agreement represents a variable interest that provides us the power to direct the most significant activities of KFPC and exposes us to the economic variability of the joint venture. As such, we have determined that we are the primary beneficiary of this variable interest entity. As a result, we have consolidated KFPC in our financial statements and reflected FPCC’s 50% ownership as a noncontrolling interest.

The following table summarizes the carrying amounts of assets and liabilities as of June 30, 2019 and December 31, 2018 for KFPC before intercompany eliminations.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation. The accompanying unaudited Condensed Consolidated Financial Statements presented in this report are for us and our consolidated subsidiaries, each of which is a wholly-owned subsidiary, except our 50% investment in our joint venture, Kraton Formosa Polymers Corporation (“KFPC”), located in Mailiao, Taiwan. KFPC is a variable interest entity for which we have determined that we are the primary beneficiary and, therefore, have consolidated into our financial statements. Our 50% investment in our joint venture located in Kashima, Japan, is accounted for under the equity method of accounting. All significant intercompany transactions have been eliminated. These interim financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly our results of operations and financial position. Amounts reported in our Condensed Consolidated Statements of Operations are not necessarily indicative of amounts expected for the respective annual periods or any other interim period, in particular due to the effect of seasonal changes and weather conditions that typically affect our sales into paving, roadmarking, roofing, and construction applications. In particular, sales volumes into these applications are generally higher in the second and third quarter of the calendar year as warm and dry weather is more conducive to paving and roofing activity.

Reclassifications

Reclassifications. Certain amounts reported in the condensed consolidated financial statements and notes to the consolidated financial statements for the prior periods have been reclassified to conform to the current reporting presentation.

Use of Estimates

Use of Estimates. The preparation of these Condensed Consolidated Financial Statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant items subject to such estimates and assumptions include:

• the useful lives of long-lived assets;

• estimates of fair value for assets acquired and liabilities assumed in business combinations;

• allowances for doubtful accounts and sales returns;

• the valuation of derivatives, deferred tax assets, property, plant and equipment, intangible assets, inventory, investments, and share-based compensation; and

•

liabilities for employee benefit obligations, environmental matters, asset retirement obligations, income tax uncertainties, and other contingencies.

Income Tax in Interim Periods

Income Tax in Interim Periods. We conduct operations in separate legal entities in different jurisdictions. As a result, income tax amounts are reflected in these Condensed Consolidated Financial Statements for each of those jurisdictions. Tax laws and tax rates vary substantially in these jurisdictions and are subject to change based on the political and economic climate in those countries. We file our tax returns in accordance with our interpretations of each jurisdiction’s tax laws. We record our tax provision or benefit on an interim basis using the estimated annual effective tax rate. This rate is applied to the current period ordinary income or loss to determine the income tax provision or benefit allocated to the interim period.

Losses from jurisdictions for which no benefit can be realized and the income tax effects of unusual and infrequent items are excluded from the estimated annual effective tax rate. Valuation allowances are provided against the future tax benefits that arise from the losses in jurisdictions for which there is uncertainty that they may be realized. The effects of unusual and infrequent items are recognized in the impacted interim period as discrete items.

The estimated annual effective tax rate may be significantly affected by nondeductible expenses and by our projected earnings mix by tax jurisdiction. Adjustments to the estimated annual effective income tax rate are recognized in the period during which such estimates are revised.

We have established valuation allowances against a variety of deferred tax assets, including net operating loss carryforwards, foreign tax credits and other income tax credits. Valuation allowances take into consideration our expected ability to realize these deferred tax assets and reduce the value of such assets to the amount that is deemed more likely than not to be recoverable. Our ability to realize these deferred tax assets is dependent on achieving our forecast of future taxable operating income over an extended period of time. We review our forecast in relation to actual results and expected trends on a quarterly basis. If we fail to achieve our operating income targets, we may change our assessment regarding the recoverability of our net deferred tax assets and such change could result in a valuation allowance being recorded against some or all of our net deferred tax assets. A change in our valuation allowance would impact our income tax benefit (expense) and our stockholders’ equity and could have a significant impact on our results of operations or financial condition in future periods.

New Accounting Pronouncements

Accounting Standards Adopted in the Current Period

We have implemented all new accounting pronouncements that are in effect and that management believes would materially affect our financial statements.

In February 2016, the FASB established Topic 842, Leases, by issuing ASU 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; and ASU 2018-11, Targeted Improvements. The new standard establishes a right-of-use model (“ROU”) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than twelve months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application. The new standard provides a number of optional practical expedients in transition. We elected the following practical expedients: (1) ‘package of practical expedients’, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification, and initial direct costs; (2) the short-term lease recognition exemption for all leases that qualify; and (3) the practical expedient to not separate lease and non-lease components for all of our leases.

This standard had a material effect on our financial statements. The most significant effects relate to: (1) the recognition of new ROU assets and lease liabilities on our balance sheet for our equipment, building, and vehicle operating leases; (2) the derecognition of existing assets and liabilities for straight line lease accounting under ASC 840 Leases; and (3) providing significant new disclosures about our leasing activities. On adoption, we recognized additional operating liabilities of $70.9 million, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objective of this ASU is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. This standard is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2017-12 was completed during 2018 and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2017-12 effective January 1, 2019.

In October 2018, the FASB issued 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. This standard is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2018-16 was completed during 2018, and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2018-16 effective January 1, 2019.

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted for any interim period after issuance of the ASU. Our analysis of ASU 2018-02 was completed during 2018, and there is no material change to our financial position, results of operations, and cash flows. We adopted ASU 2018-02 effective January 1, 2019.

New Accounting Standards to be Adopted in Future Periods

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and early adoption is permitted for annual or interim goodwill impairment tests performed on testing dates after January 1, 2017. Our evaluation of this standard is currently ongoing, and we expect to adopt ASU 2017-04 effective on January 1, 2020.

In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This standard is effective for fiscal years beginning after December 15, 2019, and early adoption is permitted for any interim period after issuance of the ASU. Our evaluation of this standard is currently ongoing, and we expect to adopt ASU 2018-18 effective on January 1, 2020.

Revenue from Contract with Customers

Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally, this occurs at a point in time when the transfer of risk and title to the product transfers to the customer. Our standard terms of delivery are included in our contracts of sale, order confirmation documents, and invoices. As such, all revenue is considered revenue recognized from contracts with customers, and we do not have other sources of revenue. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Revenue is recognized net of sales tax, value-added taxes, and other taxes. Shipping and other transportation costs charged to customers are recorded in both revenue and cost of goods sold. We do not have any material significant payment terms as payment is received at or shortly after the point of sale. Certain customers may receive cash-based incentives (including rebates, price supports, and sales commission), which are accounted for as variable consideration. We estimate rebates and price supports based on the expected amount to be provided to customers and reduce revenues recognized once the performance obligation has been met. Sales commissions are recorded as an increase in cost of goods sold once the performance obligation has been met. We do not expect to have significant changes in our estimates for variable considerations.

We have deferred revenue of $13.2 million related to contractual commitments with customers for which the performance obligation will be satisfied over time, which will range from one to ten years. The revenue associated with these performance obligations is recognized as the obligation is satisfied, which occurs as a volume based metric over time when the transfer of risk and title of finished products transfer to the customer.

Occasionally, we enter into bill-and-hold contracts, where we invoice the customer for products even though we retain possession of the products until a point in time in the future when the products will be shipped to the customer. In these contracts, the primary performance obligation is satisfied at a point in time when the product is segregated from our general inventory, it is ready for shipment to customer, and we do not have the ability to use the product or direct it to another customer. Additionally, we have a secondary performance obligation related to custodial costs, including storage and freight, which is satisfied over time once the product has been delivered to the customer. During the three and six months ended June 30, 2019, we recognized $0.3 million and $6.0 million of revenue related to these arrangements, respectively.

Summary of financial assets and liabilities accounted for at fair value on a recurring basis

The following tables set forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2019 and December 31, 2018. These financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which judgment may affect the valuation of their fair value and placement within the fair value hierarchy levels. As of June 30, 2019 and December 31, 2018, the Company has no assets or liabilities utilizing significant unobservable inputs (or Level 3) to derive its estimated fair values.
