Presentation of Financial, Market and Legal Data
We present our financial information on a consolidated basis. Unless otherwise noted, when we refer to dollars, we mean U.S. dollars.
Unless otherwise specifically noted, market and market share data in this Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2021 (the "Report") are our own estimates or derived from sources described in our Annual Report on Form 10-K for the year ended December 31, 2020 ("Annual Report on Form 10-K") filed on February 23, 2021. Our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under “Forward-Looking Statements” and “Risk Factors” in this Report and in our Annual Report on Form 10-K. We cannot guarantee the accuracy or completeness of this market and market share data and have not independently verified it. None of the sources have consented to the disclosure or use of data in this Report.
Forward-Looking Statements
Some of the statements under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and elsewhere in this Report may contain forward-looking statements that reflect our current views with respect to, among other things, future events and financial performance. You can identify these forward-looking statements by the use of forward-looking words such as “will,” “may,” “plan,” “estimate,” “project,” “believe,” “anticipate,” “expect,” “foresee,” “intend,” “should,” “would,” “could,” “target,” “goal,” “continue to,” “positioned to,” “are confident,” or the negative versions of those words or other comparable words. Any forward-looking statements contained in this Report are based upon our historical performance and on our current plans, estimates and expectations considering information currently available to us. The inclusion of this forward-looking information should not be regarded as a representation by us that the future plans, estimates, or expectations contemplated by us will be achieved. Our expectations and targets are not predictions of actual performance and historically our performance has deviated, often significantly, from our expectations and targets. These forward-looking statements are subject to various risks and uncertainties and assumptions relating to our operations, financial results, financial condition, business, prospects, growth strategy and liquidity. Accordingly, there are or will be important factors that could cause our actual results to differ materially from those indicated in these statements. We believe that these factors include, but are not limited to:
2

the ultimate impact that the COVID-19 pandemic has on our business, results of operations, financial condition and cash flows;
the cyclical nature of our business and the selling prices of our products may lead to periods of reduced profitability and net losses in the future;
the possibility that we may be unable to implement our business strategies, including our ability to secure and maintain longer-term customer contracts, in an effective manner;
the risks and uncertainties associated with litigation, arbitration, and like disputes, including the current stockholder litigation and disputes related to contractual commitments;
the possibility that global graphite electrode overcapacity may adversely affect graphite electrode prices;
pricing for graphite electrodes has historically been cyclical and the price of graphite electrodes may continue to decline in the future;
the sensitivity of our business and operating results to economic conditions and the possibility others may not be able to fulfill their obligations to us in a timely fashion or at all;
our dependence on the global steel industry generally and the electric arc furnace steel industry in particular;
the competitiveness of the graphite electrode industry;
our dependence on the supply of petroleum needle coke;
our dependence on supplies of raw materials (in addition to petroleum needle coke) and energy;
our manufacturing operations are subject to hazards;
changes in, or more stringent enforcement of, health, safety and environmental regulations applicable to our manufacturing operations and facilities;
the legal, compliance, economic, social and political risks associated with our substantial operations in multiple countries;
the possibility that fluctuation of foreign currency exchange rates could materially harm our financial results;
the possibility that our results of operations could deteriorate if our manufacturing operations were substantially disrupted for an extended period, including as a result of equipment failure, climate change, regulatory issues, natural disasters, public health crises, such as the COVID-19 pandemic, political crises or other catastrophic events;
our dependence on third parties for certain construction, maintenance, engineering, transportation, warehousing and logistics services;
the possibility that we are unable to recruit or retain key management and plant operating personnel or successfully negotiate with the representatives of our employees, including labor unions;
the possibility that we may divest or acquire businesses, which could require significant management attention or disrupt our business;
the sensitivity of goodwill on our balance sheet to changes in the market;
the possibility that we are subject to information technology systems failures, cybersecurity attacks, network disruptions and breaches of data security;
our dependence on protecting our intellectual property;
the possibility that third parties may claim that our products or processes infringe their intellectual property rights;
the possibility that significant changes in our jurisdictional earnings mix or in the tax laws of those jurisdictions could adversely affect our business;
the possibility that our indebtedness could limit our financial and operating activities or that our cash flows may not be sufficient to service our indebtedness;
the possibility that restrictive covenants in our financing agreements could restrict or limit our operations;
3

the fact that borrowings under certain of our existing financing agreements subject us to interest rate risk;
the possibility of a lowering or withdrawal of the ratings assigned to our debt;
the possibility that disruptions in the capital and credit markets could adversely affect our results of operations, cash flows and financial condition, or those of our customers and suppliers;
the possibility that concentrated ownership of our common stock may prevent minority stockholders from influencing significant corporate decisions;
the possibility that we may not pay cash dividends on our common stock in the future;
the fact that our stockholders have the right to engage or invest in the same or similar businesses as us;
the possibility that the market price of our common stock could be negatively affected by sales of substantial amounts of our common stock in the public markets, including by Brookfield Asset Management Inc. and its affiliates;
the fact that certain provisions of our Amended and Restated Certificate of Incorporation and our Amended and Restated By-Laws could hinder, delay or prevent a change of control;
the fact that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders; and
the loss of our status as a “controlled company” within the meaning of the New York Stock Exchange corporate governance standards, which will result in us no longer qualifying for exemptions from certain corporate governance requirements.

These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements, including the Risk Factors sections, that are included in our Annual Report on Form 10-K, and other filings with the Securities and Exchange Commission ("SEC"). The forward-looking statements made in this Report relate only to events as of the date on which the statements are made. We do not undertake any obligation to publicly update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise.
If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this Report that could cause actual results to differ before making an investment decision to purchase our common stock. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

(1)Organization and Summary of Significant Accounting Policies
A. Organization
GrafTech International Ltd. (the “Company”) is a leading manufacturer of high quality graphite electrode products essential to the production of electric arc furnace steel and other ferrous and non-ferrous metals. References herein to “GrafTech,” the “Company,” “we,” “our,” or “us” refer collectively to GrafTech International Ltd. and its subsidiaries.
On August 15, 2015, we became an indirect wholly owned subsidiary of Brookfield Asset Management Inc. (together with its affiliates, “Brookfield”). In April 2018, we completed our initial public offering ("IPO") of 38,097,525 shares of our common stock held by Brookfield at a price of $15.00 per share. We did not receive any proceeds related to the IPO. Our common stock is listed on the NYSE under the symbol “EAF.” Brookfield has since distributed a portion of its GrafTech common stock to the owners in the Brookfield consortium and sold shares of GrafTech common stock in public and private transactions, resulting in Brookfield's ownership of outstanding shares of GrafTech common stock decreasing to 55.3% as of December 31, 2020 and 23.9% as of June 30, 2021.
The Company’s only reportable segment, Industrial Materials, is comprised of our two major product categories: graphite electrodes and petroleum needle coke products. Petroleum needle coke is a key raw material used in the production of graphite electrodes. The Company's vision is to provide highly engineered graphite electrode services, solutions and products to electric arc furnace operators.
B. Basis of Presentation
The interim condensed consolidated financial statements are unaudited; however, in the opinion of management, they have been prepared in accordance with Rule 10-01 of Regulation S-X and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The December 31, 2020 financial position data included herein was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 ("Annual Report on Form 10-K"), filed on February 23, 2021, but does not include all disclosures required by GAAP in audited financial statements. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the accompanying notes, contained in our Annual Report on Form 10-K.
The unaudited condensed consolidated financial statements reflect all adjustments (all of which are of a normal, recurring nature) which management considers necessary for a fair statement of financial position, results of operations, comprehensive income and cash flows for the interim periods presented. The results for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.
C. New Accounting Standards
Recently Adopted Accounting Standards
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 is intended to improve consistent application of Topic 740 and simplify the accounting for income taxes. This pronouncement removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance. ASU 2019-12 is effective for annual and interim reporting periods beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU 2019-12 on January 1, 2021, with an immaterial effect on our financial position, results of operations and cash flows.
Accounting Standards Not Yet Adopted
In March 2020, the FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). This pronouncement contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform. ASU 2020-04 is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 can be elected for both interim and annual periods from March 12, 2020 through December 31, 2022. We plan to adopt ASU 2020-04 as of January 1, 2023. The adoption of ASU 2020-04 is not expected to have a material impact on our financial position, results of operations and cash flows.

The Graphite Electrodes revenue categories include only graphite electrodes manufactured by GrafTech. The revenue category “By-products and Other” also includes resales of low-grade electrodes purchased from third-party suppliers, which represent a minimal contribution to our profitability.
Contract Balances
Substantially all of the Company's receivables relate to contracts with customers. Accounts receivables are recorded when the right to consideration becomes unconditional. Payment terms on invoices range from 30 to 120 days depending on the customary business practices of the jurisdictions in which we do business.
Certain short-term and longer-term sales contracts require up-front payments prior to the Company’s fulfillment of any performance obligation. These contract liabilities are recorded as current or long-term deferred revenue, depending on the lag between the pre-payment and the expected delivery of the related products. Additionally, deferred revenue or contract assets originate from contracts where the allocation of the transaction price to the performance obligations based on their relative stand-alone selling prices results in the timing of revenue recognition being different from the timing of the invoicing. In this case, deferred revenue is amortized into revenue based on the transaction price allocated to the remaining performance obligations and contract assets are realized through the contract invoicing.
Contract assets as of June 30, 2021 were $2.1 million, of which $1.8 million and $0.3 million are included in "Prepaid expenses and other current assets" and "Other long-term assets," respectively, on the Condensed Consolidated Balance Sheets. Contract assets as of December 31, 2020 were $2.7 million, of which $1.5 million and $1.2 million are included in "Prepaid expenses and other current assets" and "Other long-term assets," respectively, on the Condensed Consolidated Balance Sheets.
Current deferred revenue is included in "Other accrued liabilities" and long-term deferred revenue is included in "Other long-term obligations" on the Condensed Consolidated Balance Sheets.

Transaction Price Allocated to the Remaining Performance Obligations

The following table presents estimated revenues expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of reporting period. The estimated revenues do not include contracts with original duration of one year or less. During the challenging market conditions in 2020, we were able to work with our customers to develop mutually beneficial solutions to their challenges, including volume commitments. We have negotiated long-term sales agreement ("LTA") modifications with many of these customers. We also worked to preserve our rights under the LTAs in a few arbitrations that arose from some non-performance and other disputes during the year.

We recorded $499 million of LTA revenue in the first six months of 2021, and we expect to record approximately $425 million to $525 million of LTA revenue for the remainder of 2021. The remaining revenue associated with our LTAs is expected to be approximately as follows:
20222023 through 2024
(Dollars in millions)
Estimated LTA revenue
$910-$1,010
$350-$450(1)
(1) Includes expected termination fees from a few customers that have failed to meet certain obligations under their LTAs.
The majority of the LTAs are defined as pre-determined fixed annual volume contracts while a small portion are defined with a specified volume range. For the year 2021 and beyond, the contractual revenue amounts above are based upon the minimum volume for those contracts with specified ranges. The actual revenue realized from these contracted volumes may vary in timing and total due to contract non-performance, contract arbitrations, credit risk associated with certain customers facing financial challenges and customer demand related to contracted volume ranges.
(3)Goodwill and Other Intangible Assets
We are required to review goodwill and indefinite-lived intangible assets annually for impairment. Goodwill impairment is tested at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Goodwill balance was $171.1 million as of June 30, 2021 and December 31, 2020.

2018 Term Loan and 2018 Revolving Credit Facility

In February 2018, the Company entered into a credit agreement (the “2018 Credit Agreement”), which provides for (i) a $2,250 million senior secured term facility (the “2018 Term Loan Facility”) after giving effect to the June 2018 amendment (the “First Amendment”) that increased the aggregate principal amount of the 2018 Term Loan Facility from $1,500 million to $2,250 million and (ii) a $250 million senior secured revolving credit facility (the “2018 Revolving Credit Facility” and, together with the 2018 Term Loan Facility, the “Senior Secured Credit Facilities”). GrafTech Finance Inc. (“GrafTech Finance”) is the sole borrower under the 2018 Term Loan Facility while GrafTech Finance, GrafTech Switzerland SA (“Swissco”) and GrafTech Luxembourg II S.à.r.l. (“Luxembourg Holdco” and, together with GrafTech Finance and Swissco, the “Co-Borrowers”) are co-borrowers under the 2018 Revolving Credit Facility. The 2018 Term Loan Facility and the 2018 Revolving Credit Facility mature on February 12, 2025 and February 12, 2023, respectively.
The 2018 Term Loan Facility bears interest, at our option, at a rate equal to either (i) the Adjusted LIBO Rate (as defined in the 2018 Credit Agreement), plus an applicable margin equal to 3.00% per annum following an amendment in February 2021 (the “Second Amendment”) that decreased the Applicable Rate (as defined in the 2018 Credit Agreement) by 0.50% for each pricing level or (ii) the ABR Rate (as defined in the 2018 Credit Agreement), plus an applicable margin equal to
13

PART I (CONT'D)
GRAFTECH INTERNATIONAL LTD. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

2.00% per annum following the Second Amendment, in each case with one step down of 25 basis points based on achievement of certain public ratings of the 2018 Term Loan Facility. The Second Amendment also decreased the interest rate floor from 1.0% to 0.50% for the 2018 Term Loan Facility.
The 2018 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) the Adjusted LIBO Rate, plus an applicable margin initially equal to 3.75% per annum or (ii) the ABR Rate, plus an applicable margin initially equal to 2.75% per annum, in each case with two 25 basis point step downs based on achievement of certain senior secured first lien net leverage ratios. In addition, we are required to pay a quarterly commitment fee on the unused commitments under the 2018 Revolving Credit Facility in an amount equal to 0.25% per annum.
The Senior Secured Credit Facilities are guaranteed by each of our domestic subsidiaries, subject to certain customary exceptions, and by GrafTech Luxembourg I S.à.r.l., a Luxembourg société à responsabilité limitée and an indirect wholly owned subsidiary of GrafTech, Luxembourg HoldCo, and Swissco (collectively, the “Guarantors”) with respect to all obligations under the 2018 Credit Agreement of each of our foreign subsidiaries that is a Controlled Foreign Corporation (within the meaning of Section 956 of the Internal Revenue Code of 1986, as amended from time to time (the “Code”)).
All obligations under the 2018 Credit Agreement are secured, subject to certain exceptions, by: (i) a pledge of all of the equity securities of each domestic Guarantor and of each other direct, wholly owned domestic subsidiary of GrafTech and any Guarantor, (ii) a pledge on no more than 65% of the equity interests of each subsidiary that is a Controlled Foreign Corporation (within the meaning of Section 956 of the Code), and (iii) security interests in, and mortgages on, personal property and material real property of each domestic Guarantor, subject to permitted liens and certain exceptions specified in the 2018 Credit Agreement. The obligations of each foreign subsidiary of GrafTech that is a Controlled Foreign Corporation under the 2018 Revolving Credit Facility are secured by (i) a pledge of all of the equity securities of each Guarantor that is a Controlled Foreign Corporation and of each direct, wholly owned subsidiary of any Guarantor that is a Controlled Foreign Corporation, and (ii) security interests in certain receivables and personal property of each Guarantor that is a Controlled Foreign Corporation, subject to permitted liens and certain exceptions specified in the 2018 Credit Agreement.
The 2018 Term Loan Facility amortizes at a rate of $112.5 million a year payable in equal quarterly installments, with the remainder due at maturity. The Co-Borrowers are permitted to make voluntary prepayments at any time without premium or penalty. GrafTech Finance is required to make prepayments under the 2018 Term Loan Facility (without payment of a premium) with (i) net cash proceeds from non-ordinary course asset sales (subject to customary reinvestment rights and other customary exceptions and exclusions), and (ii) commencing with the Company’s fiscal year ended December 31, 2019, 75% of Excess Cash Flow (as defined in the 2018 Credit Agreement), subject to step-downs to 50% and 0% of Excess Cash Flow based on achievement of a senior secured first lien net leverage ratio greater than 1.25 to 1.00 but less than or equal to 1.75 to 1.00 and less than or equal to 1.25 to 1.00, respectively. Scheduled quarterly amortization payments of the 2018 Term Loan Facility during any calendar year reduce, on a dollar-for-dollar basis, the amount of the required Excess Cash Flow prepayment for such calendar year, and the aggregate amount of Excess Cash Flow prepayments for any calendar year reduce subsequent quarterly amortization payments of the 2018 Term Loan Facility as directed by GrafTech Finance. As of June 30, 2021, we have satisfied all amortization requirements through prepayments through the maturity date.
The 2018 Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to GrafTech and restricted subsidiaries, including, among other things, restrictions on indebtedness, liens, investments, fundamental changes, dispositions, and dividends and other distributions. The 2018 Credit Agreement contains a financial covenant that requires GrafTech to maintain a senior secured first lien net leverage ratio not greater than 4.00:1.00 when the aggregate principal amount of borrowings under the 2018 Revolving Credit Facility and outstanding letters of credit issued under the 2018 Revolving Credit Facility (except for undrawn letters of credit in an aggregate amount equal to or less than $35 million), taken together, exceed 35% of the total amount of commitments under the 2018 Revolving Credit Facility. The 2018 Credit Agreement also contains customary events of default.
2020 Senior Notes
In December 2020, GrafTech Finance issued $500 million aggregate principal amount of 4.625% senior secured notes due 2028 (the “2020 Senior Notes”) in a private offering. The 2020 Senior Notes and related guarantees are secured on a pari passu basis by the collateral securing the Senior Secured Credit Facilities. All of the proceeds from the 2020 Senior Notes were used to partially repay borrowings under our 2018 Term Loan Facility.
The 2020 Senior Notes pay interest in arrears on June 15 and December 15 of each year, with the principal due in full on December 15, 2028. Prior to December 15, 2023, up to 40% of the 2020 Senior Notes may be redeemed with the net cash proceeds of certain equity offerings at a price equal to 104.625% of the principal amount thereof, together with accrued and unpaid interest, if any. The 2020 Senior Notes may be redeemed, in whole or in part, at any time prior to December 15, 2023 at a price equal to 100% of the principal amount of the notes redeemed plus a premium together with accrued and unpaid interest,

if any, to, but not including, the redemption date. Thereafter, the 2020 Senior Notes may be redeemed, in whole or in part, at various prices depending on the date redeemed.
The indenture governing the 2020 Senior Notes (the “Indenture”) contains certain covenants that, among other things, limit the Company’s ability, and the ability of certain of its subsidiaries, to incur or guarantee additional indebtedness or issue preferred stock, pay distributions on, redeem or repurchase capital stock or redeem or repurchase subordinated debt, incur or suffer to exist liens securing indebtedness, make certain investments, engage in certain transactions with affiliates, consummate certain asset sales and effect a consolidation or merger, or sell, transfer, lease or otherwise dispose of all or substantially all assets. Pursuant to the Indenture, if our pro forma consolidated first lien net leverage ratio is no greater than 2.00 to 1.00, we can make restricted payments so long as no default or event of default has occurred and is continuing. If our pro forma consolidated first lien net leverage ratio is greater than 2.00 to 1.00, we can make restricted payments pursuant to certain baskets.
The Indenture contains events of default customary for agreements of its type (with customary grace periods, as applicable) and provides that, upon the occurrence of an event of default arising from certain events of bankruptcy or insolvency with respect to the Company or GrafTech Finance, all outstanding 2020 Senior Notes will become due and payable immediately without further action or notice. If any other type of event of default occurs and is continuing, then the trustee or the holders of at least 30% in principal amount of the then outstanding 2020 Senior Notes may declare all of the 2020 Senior Notes to be due and payable immediately.

Interest Rates
The 2020 Senior Notes carry a fixed interest rate of 4.625%. The 2018 Credit Agreement had an effective interest rate of 3.50% as of June 30, 2021 and 4.50% as of December 31, 2020. See Note 4 "Debt and Liquidity" for details of these transactions.
During the three months ended June 30, 2021, we made a prepayment of $50.0 million under our 2018 Term Loan Facility. In connection with this, we recorded $0.4 million of accelerated amortization of the debt issuance costs and $0.3 million of accelerated accretion of the original issue discount.
During the six months ended June 30, 2021, we made prepayments for a total of $200.0 million under our 2018 Term Loan Facility. In connection with this, we recorded $2.0 million of accelerated amortization of the debt issuance costs and $1.2 million of accelerated accretion of the original issue discount. We also recorded $1.6 million of modification costs related to the term loan repricing in the first quarter of 2021. See Note 4 "Debt and Liquidity" for details of these transactions.
The Company has several interest rate swap contracts to fix the cash flows associated with the risk in variability in the one-month USD. London Interbank Offered Rate ("USD LIBOR") for the 2018 Credit Agreement debt. See Note 9 "Derivative Instruments" for details of these transactions.

(7) Contingencies
Legal Proceedings
We are involved in various investigations, lawsuits, claims, demands, environmental compliance programs and other legal proceedings arising out of or incidental to the conduct of our business. While it is not possible to determine the ultimate disposition of each of these matters, we do not believe that their ultimate disposition will have a material adverse effect on our financial position, results of operations or cash flows. Additionally, we are involved in the following legal proceedings described below.
Pending litigation in Brazil has been brought by employees seeking to recover additional amounts and interest thereon under certain wage increase provisions applicable in 1989 and 1990 under collective bargaining agreements to which employers in the Bahia region of Brazil were a party (including our subsidiary in Brazil). Companies in Brazil have settled claims arising out of these provisions and, in May 2015, the litigation was remanded by the Brazilian Supreme Court in favor of the employees union. After denying an interim appeal by the Bahia region employers on June 26, 2019, the Brazilian Supreme Court finally ruled in favor of the employees union on September 26, 2019. The employers union has determined not to seek annulment of such decision. Separately, on October 1, 2015, a related action was filed by current and former employees against our subsidiary in Brazil to recover amounts under such provisions, plus interest thereon, which amounts together with interest could be material to us. If the Brazilian Supreme Court proceeding above had been determined in favor of the employers union, it would also have resolved this proceeding in our favor. In the first quarter of 2017, the state court initially ruled in favor of the employees. We appealed this state court ruling, and the appellate court issued a decision in our favor on May 19, 2020. The employees have further appealed and, on December 16, 2020, the court upheld the decision in favor of GrafTech Brazil. On February 22, 2021, the employees filed a further appeal and, on April 28, 2021, the court rejected the employees' appeal in favor of GrafTech Brazil. The employees filed a further appeal. As of June 30, 2021, we are unable to assess the potential loss associated with these proceedings as the claims do not currently specify the number of employees seeking damages or the amount of damages being sought.
Product Warranties
We generally sell products with a limited warranty. We accrue for known warranty claims if a loss is probable and can be reasonably estimated. We also accrue for estimated warranty claims incurred based on a historical claims charge analysis. Claims accrued but not yet paid and the related activity within the accrual for the six months ended June 30, 2021, are presented below:

Tax Receivable Agreement
On April 23, 2018, the Company entered into the tax receivable agreement (“TRA”) that provides Brookfield, as the sole pre-IPO stockholder, the right to receive future payments from us for 85% of the amount of cash savings, if any, in U.S. federal income tax and Swiss tax that we and our subsidiaries realize as a result of the utilization of the pre-IPO tax assets. In addition, we will pay interest on the payments we will make to Brookfield with respect to the amount of these cash savings from the due date (without extensions) of our tax return where we realize these savings to the payment date at a rate equal to LIBOR plus 1.00% per annum. The term of the TRA commenced on April 23, 2018 and will continue until there is no potential for any future tax benefit payments.
As of June 30, 2021, the total TRA liability was $19.1 million, of which $3.9 million was classified as a current liability in "Related party payable-tax receivable agreement" and $15.2 million remained as a long-term liability in "Related party payable-tax receivable agreement" on the balance sheet. As of December 31, 2020, the total TRA liability was $40.9 million, of which $21.8 million was classified as a current liability in "Related party payable - tax receivable agreement" on the balance sheet, as we expected this portion to be settled within twelve months, and $19.1 million of the liability remained as a long-term liability in "Related party payable - tax receivable agreement" on the balance sheet.

Long-term Incentive Plan
The long-term incentive plan ("LTIP") was adopted by the Company in August 2015 and amended and restated in March 2018. The purpose of the plan was to retain senior management of the Company, to incentivize them to make decisions with a long-term view and to influence behavior in a way that is consistent with maximizing value for the pre-IPO stockholder of the Company in a prudent manner. Each participant was allocated a number of profit units, with a maximum of 30,000 profit units ("Profit Units") available under the plan. Awards of Profit Units generally vested in equal increments over a five-year period beginning on the first anniversary of the grant date of the Profit Units, subject to continued employment with the Company through each vesting date. If a participant ceased to provide services prior to any applicable vesting date for any reason, other than a termination for cause, then the participant forfeited all unvested Profit Units and any vested Profit Units remained outstanding. If a Participant had been terminated for cause, both vested and unvested Profit Units would have been forfeited. Upon a "Change in Control" (as defined in the LTIP), the Profit Units entitled the participant to a payment based on a percentage of the sum of (i) all net "Sale Proceeds" (as defined in the LTIP) received by Brookfield Capital IV L.P. and its affiliates ("Brookfield Capital IV") less (ii) the "Threshold Value" (as defined in the LTIP), with such payment amount being determined by the Company's Board of Directors in its sole discretion. In the event that, in connection with a Change in Control, Brookfield Capital IV disposes of less than 100% of its ownership interest in the Company, the amount of the Sale Proceeds in excess of the Threshold Value shall be determined on a pro-rata basis by reference to the percentage of ownership interest disposed, as determined by the Board of Directors of the Company.
The May 2021 secondary offering of our common stock by Brookfield Capital IV constituted a "Change in Control" under the LTIP. A "Change in Control" under the LTIP is defined as, among other things, a transaction or series of transactions (including, without limitation, the consummation of a combination, share purchases, recapitalization, redemption, issuance of capital stock, consolidation, reorganization or otherwise) pursuant to which following a public offering of the Company’s stock, Brookfield Capital IV ceases to have a beneficial ownership interest in at least 30% of the Company’s outstanding voting securities (effective on the first of such date). Upon completion of the May 2021 secondary offering, Brookfield beneficially owned approximately 24% of the Company's outstanding voting securities. Accordingly, the Company settled the vested Profit Units in lump sum payment within 30 days following a Change in Control. The settlement of the Profit Units consisted of a pre-tax charge of $73.4 million, of which $30.7 million was recorded in cost of sales and $42.7 million was recorded in selling and administrative expense. As of June 30, 2021, $61.5 million of the charges have been settled in cash by the Company while the remainder of the liability, related to payroll taxes, is expected to be paid in the third quarter of 2021, which will satisfy all obligations under the LTIP.

(8) Income Taxes
We compute and apply to ordinary income an estimated annual effective tax rate on a quarterly basis based on current and forecasted business levels and activities, including the mix of domestic and foreign results and enacted tax laws. The estimated annual effective tax rate is updated quarterly based on actual results and updated operating forecasts. Ordinary income refers to income (loss) before income tax expense excluding significant, unusual or infrequently occurring items. The tax effect of an unusual or infrequently occurring item is recorded in the interim period in which it occurs as a discrete item of tax.

The following table summarizes the provision for income taxes for the three and six months ended June 30, 2021 and 2020:
For the Three Months Ended June 30,For the Six Months
Ended June 30,
2021202020212020
(Dollars in thousands)
Tax expense$7,765 $19,788 $24,022 $43,734 
Pretax income35,930 112,564 150,986 258,778 
Effective tax rates21.6 %17.6 %15.9 %16.9 %
The effective tax rate for the three months ended June 30, 2021 was 21.6%. This rate differs from the U.S. statutory rate of 21% primarily due to worldwide earnings from various countries taxed at different rates, which is partially offset by the net combined impact related to the U.S. taxation of global intangible low taxed income ("GILTI"), and Foreign Tax Credits ("FTCs"). A portion of the one-time Change in Control charges recorded in the three months ended June 30, 2021 was not deductible and contributed to the increase in the effective rate. We expect the full year effective tax rate to be approximately 16% to 17%.
The effective tax rate for the three months ended June 30, 2020 was 17.6%. This rate differs from the U.S. statutory rate of 21% primarily due to worldwide earnings from various countries taxed at different rates.
The tax expense decreased from $19.8 million for the three months ended June 30, 2020 to $7.8 million for the three months June 30, 2021. This change is primarily related to a reduction in pretax income, worldwide earnings from various countries taxed at different rates and U.S. taxation of GILTI.
For the six months ended June 30, 2021, the effective tax rate of 15.9% differs from the U.S. statutory rate of 21% primarily due to worldwide earnings from various countries taxed at different rates which is partially offset by the net combined impact related to the U.S. taxation of GILTI and FTCs.
For the six months ended June 30, 2020, the effective tax rate of 16.9% differs from the U.S. statutory rate of 21% primarily due to worldwide earnings from various countries taxed at different rates.
The tax expense decreased from $43.7 million for the six months ended June 30, 2020 to $24.0 million for the six months ended June 30, 2021. This change is primarily related to the reduction in pretax income, worldwide earnings from various countries taxed at different rates and the U.S. taxation of GILTI.
As of June 30, 2021, we had unrecognized tax benefits of $0.1 million, which, if recognized, would have a favorable impact on our effective tax rate.
We file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. U.S. federal tax years prior to 2017 are generally closed by statute or have been audited and settled with the applicable domestic tax authorities. Other jurisdictions are still open to examination beginning after 2014.
We continue to assess the realization of our deferred tax assets based on determinations of whether it is more likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. Examples of positive evidence would include a strong earnings history, an event or events that would increase our taxable income through a continued reduction of expenses, and tax planning strategies that would indicate an ability to realize deferred tax assets. In

(Unaudited)

circumstances where the significant positive evidence does not outweigh the negative evidence in regards to whether or not a valuation allowance is required, we have established and maintained valuation allowances on those net deferred tax assets.
(9) Derivative Instruments
We use derivative instruments as part of our overall foreign currency, interest rate and commodity risk management strategies to manage the risk of exchange rate movements that would reduce the value of our foreign cash flows, manage the risk associated with fluctuations in interest rate indices and to minimize commodity price volatility. Foreign currency exchange rate movements create a degree of risk by affecting the value of sales made and costs incurred in currencies other than the U.S. dollar.
Certain of our derivative contracts contain provisions that require us to provide collateral. Since the counterparties to these financial instruments are large commercial banks and similar financial institutions, we do not believe that we are exposed to material counterparty credit risk. We do not anticipate nonperformance by any of the counterparties to our instruments.
Foreign currency derivatives
We enter into foreign currency derivatives from time to time to attempt to manage exposure to changes in currency exchange rates. These foreign currency instruments, which include, but are not limited to, forward exchange contracts and purchased currency options, are used to hedge global currency exposures such as foreign currency denominated debt, sales, receivables, payables and purchases. 
We have no foreign currency cash flow hedges outstanding as of June 30, 2021 and December 31, 2020 and, therefore, no unrealized gains or losses reported under accumulated other comprehensive income (loss).
As of June 30, 2021, we had outstanding Mexican peso, euro, Swiss franc, South African rand and Japanese yen currency contracts with an aggregate notional amount of $80.5 million. As of December 31, 2020, we had outstanding Mexican peso, South African rand, euro, Swiss franc and Japanese yen currency contracts, with an aggregate notional amount of $71.0 million. The foreign currency derivatives outstanding as of June 30, 2021 have maturities through December 31, 2021, and were not designated as hedging instruments.
Commodity derivative contracts
We have entered into commodity derivative contracts for refined oil products. These contracts are entered into to protect against the risk that eventual cash flows related to these products will be adversely affected by future changes in prices. We had outstanding commodity derivative contracts as of June 30, 2021 with a notional amount of $38.4 million and maturities from July 2021 to June 2022. The outstanding commodity derivative contracts represented a pre-tax net unrealized gain within "Accumulated Other Comprehensive Income" of $12.8 million as of June 30, 2021. We had outstanding commodity derivative contracts as of December 31, 2020 with a notional amount of $61.3 million representing a pre-tax net unrealized loss of $2.2 million.
In connection with de-designated commodity derivative contracts, we recognized in cost of sales $0.9 million unrealized gain as of June 30, 2021 as a result of the variation in fair value from the de-designation date. This resulted from a small portion of our commodity derivative contracts that ceased to qualify for hedge accounting in the second quarter of 2021.
Interest rate swap contracts
During the third quarter of 2019, the Company entered into four interest rate swap contracts. The contracts are "pay fixed, receive variable" with notional amounts of $500 million due to mature in August 2021 and another $500 million due to mature in August 2024. The Company’s risk management objective was to fix its cash flows associated with the risk in variability in the one-month USD LIBOR for a portion of our outstanding debt. It is expected that these swaps will fix the cash flows associated with the forecasted interest payments on this notional amount of debt to an effective fixed interest rate of 5.1%, which could be lowered to 4.85% depending on credit ratings. In December 2020, in connection with the $500 million principal repayment of the 2018 Term Loan Facility, we de-designated one interest rate swap contract of $250 million notional maturing in the third quarter of 2021 and in February 2021 we closed it and recorded a $0.9 million charge in interest expense.
Additionally, in February 2021, the Company modified the three remaining swaps with notional amounts of $250 million maturing in the third quarter 2021 and $500 million maturing in the third quarter 2024 in order to align their terms

to the amended 2018 Term Loan Facility (see Note 4 "Debt and Liquidity" for details of the February 2021 repricing of the 2018 Term Loan Facility). It is expected that these swaps will fix the cash flows associated with the forecasted interest payments on this notional amount of debt to an effective fixed interest rate of 4.2%, which could be lowered to 3.95% depending on credit ratings. The modification triggered the de-designation and re-designation of the swaps. Because the modified swaps contained an other-than-insignificant financing element at re-designation date, they are considered hybrid instruments composed of a debt host and an embedded derivative. The debt host portion amounted to a liability of $8.5 million as of June 30, 2021 with $2.8 million included in "Other accrued liabilities" and $5.7 million in "Other long-term obligations". The corresponding loss is accounted for in "Accumulated Other Comprehensive income" and is amortized over the remaining life of the swaps. The embedded derivative is treated as a cash-flow hedge.
Within "Accumulated Other Comprehensive Income", the portion of the interest rate swaps qualifying as a cash flow hedge represented a net unrealized pre-tax gain of $1.9 million and a net unrealized pre-tax loss of $11.0 million as of June 30, 2021 and December 31, 2020, respectively. The fair value of these contracts was determined using Level 2 inputs.
The fair value of all derivatives is recorded as assets or liabilities on a gross basis in our Condensed Consolidated Balance Sheets. As of June 30, 2021 and December 31, 2020, the fair value of our derivatives and their respective balance sheet locations are presented in the following tables:
