W. R. Grace & Co., through its subsidiaries, is engaged in the production and sale of specialty chemicals and specialty materials on a global basis through two reportable business segments: Grace Catalysts Technologies, which includes catalysts and related products and technologies used in petrochemical, refining, and other chemical manufacturing applications; and Grace Materials Technologies, which includes specialty materials, including silica-based and silica-alumina-based materials, used in pharma/consumer, coatings, and chemical process applications.

W. R. Grace & Co. conducts all of its business through a single wholly owned subsidiary, W. R. Grace & Co.–Conn. (“Grace–Conn.”). Grace–Conn. owns all of the assets, properties and rights of W. R. Grace & Co. on a consolidated basis, either directly or through subsidiaries.

Basis of Presentation    The interim Consolidated Financial Statements presented herein are unaudited and should be read in conjunction with the Consolidated Financial Statements presented in the Company’s 2019 Annual Report on Form 10-K. Such interim Consolidated Financial Statements reflect all adjustments that, in the opinion of management, are necessary for a fair statement of the results of the interim periods presented; all such adjustments are of a normal recurring nature except for the impacts of adopting new accounting standards as discussed below. All significant intercompany accounts and transactions have been eliminated.

The results of operations for the nine-month interim period ended September 30, 2020, are not necessarily indicative of the results of operations to be attained for the year ending December 31, 2020.

Use of Estimates    The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses for the periods presented. Actual amounts could differ from those estimates, and the differences could be material. Changes in estimates are recorded in the period identified. Grace’s accounting measurements that are most affected by management’s estimates of future events are:

•	The effective tax rate and realization values of net deferred tax assets, which depend on projections of future taxable income;

•	Pension and postretirement liabilities, which depend on assumptions regarding participant life spans, future inflation, discount rates and total returns on invested funds (see Note 6);

•	Carrying values of goodwill and other intangible assets, which depend on assumptions of future earnings and cash flows; and

•	Contingent liabilities, which depend on an assessment of the probability of loss and an estimate of ultimate obligation, such as litigation and arbitration; and product, environmental, and other legacy liabilities (see Note 8).

Reclassifications    Certain amounts in prior years’ Consolidated Financial Statements have been reclassified to conform to the current year presentation. Such reclassifications have not materially affected previously reported amounts in the Consolidated Financial Statements.

Recently Issued Accounting Standards    In December 2019, the FASB issued ASU 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” This update clarifies and amends existing guidance, including removing certain exceptions to the general principles in Topic 740, and improves consistent application of and simplifies U.S. GAAP for other areas of Topic 740. This update is effective for Grace on January 1, 2021, with early adoption permitted. Grace is currently evaluating the effect and timing of adoption.

Recently Adopted Accounting Standards    In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This update is intended to ease the potential burden in accounting for and recognizing the effects of reference rate reform. It provides optional practical expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform, if certain criteria are met. This update

---

became effective on March 12, 2020, and is available for use through December 31, 2022. Grace expects to utilize the practical expedients provided by this update in accounting for contract modifications and/or hedging transactions during the effective period. Grace expects the update to significantly reduce the effects of reference rate reform on the Consolidated Financial Statements.

In August 2018, the FASB issued ASU 2018-14 “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20).” This update revises disclosure requirements related to defined benefit pension and other postretirement plans. Grace adopted this update in the 2020 first quarter, and it did not have a material effect on the Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments.” This update requires companies to implement an impairment model based on expected credit losses, rather than probable incurred losses. Grace adopted this update in the 2020 first quarter, and it did not have a material effect on the Consolidated Financial Statements.

Inventories are stated at the lower of cost or net realizable value, and cost is determined using FIFO. Inventories consisted of the following at September 30, 2020, and December 31, 2019:

(In millions)	September 30, 2020				December 31, 2019
Raw materials	$	58.6			$	64.2
In process	43.0				55.7
Finished products	120.4				154.4
Other	33.7				35.6
Total inventory	$	255.7			$	309.9

During the three months ended June 30, 2020, Grace implemented changes to its Refining Technologies manufacturing operations to improve capital and operating efficiencies. This included key organizational changes and optimization of plant and manufacturing processes at Grace’s three hydroprocessing catalyst manufacturing sites. As a result of these changes, Grace recorded a pre-tax charge of $19.7 million related to a write-off of inventory now deemed obsolete based on the process changes.

Grace also maintains a $400 million revolving credit facility. As of September 30, 2020, the available credit under this facility was reduced to $391.8 million by outstanding letters of credit.

The principal maturities of debt outstanding at September 30, 2020, were as follows:

	(In millions)

Senior Notes due 2027    On June 26, 2020, Grace–Conn. (the “Issuer”) and certain of the Company’s existing domestic subsidiaries (together with the Company, the “Guarantors”), completed the sale of $750 million aggregate principal amount of 4.875% Notes due 2027 (the “Senior Notes due 2027”) for net proceeds of $741.6 million. The Senior Notes due 2027 were priced at 100% of par and were offered and sold pursuant to exemptions from registration under the Securities Act of 1933, as amended (the "Securities Act"). The Senior Notes due 2027 were issued pursuant to an indenture, dated as of September 16, 2014 (the “Base Indenture”), as supplemented by that certain third supplemental indenture, dated as of June 26, 2020 (the “Third Supplemental Indenture”), by and among the Issuer, the Guarantors and the trustee thereunder (the “Trustee”). The Base Indenture, together with the Third Supplemental Indenture, are referred to below as the “Indenture.”

On July 13, 2020, Grace used the net proceeds, together with cash on hand, to redeem the $700.0 million Senior Notes due 2021 for $748.0 million, including $10.1 million of interest accrued through the date of redemption and a $37.9 million make-whole premium. During the three months ended September 30, 2020, Grace recognized a charge related to the debt refinancing of $39.4 million, including the make-whole premium.

Interest is payable on the Senior Notes due 2027 on each June 15 and December 15, commencing December 15, 2020.

---

Grace may redeem all or a portion of the Senior Notes due 2027 at any time prior to June 15, 2023, at a price equal to 100% of the principal amount of the Senior Notes due 2027 redeemed plus accrued and unpaid interest, if any, to but excluding the redemption date plus a make-whole premium. At any time on or after June 15, 2023, Grace may redeem the Senior Notes due 2027, in whole or in part, at the redemption prices set forth in the Third Supplemental Indenture, in each case plus accrued and unpaid interest, if any, to but excluding the redemption date. The Senior Notes due 2027 will mature on June 15, 2027.

If a change of control of the Company occurs while the Senior Notes due 2027 are rated below investment grade, or is followed by a below investment grade rating, subject to certain exceptions, each holder shall have the right to require that the Issuer repurchase all or a portion of such holder’s Senior Notes due 2027 at a purchase price of 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, on the Senior Notes due 2027 repurchased, to but excluding, the date of repurchase.

The Senior Notes due 2027 and guarantees are senior unsecured obligations of the Issuer and the Guarantors, respectively, and will rank equally with all of the existing and future unsubordinated obligations of the Issuer and the Guarantors, respectively. The Senior Notes due 2027 and the guarantees are effectively subordinated to any secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to the debt and other liabilities of the Company’s non-guarantor subsidiaries.

The Senior Notes due 2027 were issued subject to covenants that limit the ability of the Company, the Issuer, and certain of the Company’s subsidiaries to: (i) incur liens on assets; (ii) enter into sale and leaseback transactions larger than the greater of $100 million or 2.5% of total assets; and (iii) merge or consolidate with another company; subject to certain exceptions and qualifications. Grace is in compliance with those covenants.

The Senior Notes due 2027 were issued subject to customary events of default, which include (subject in certain cases to customary grace and cure periods), among others, nonpayment of principal or interest; breach of other agreements in the Indenture; failure to pay certain other indebtedness; failure to discharge a final judgment for payment of the greater of (i) $100 million and (ii) 2.5% of Total Assets (as defined in the Indenture) or more (excluding any amounts covered by insurance or indemnities) rendered against the Issuer or any of its significant subsidiaries; and certain events of bankruptcy or insolvency. Generally, if any event of default occurs, the Trustee or the holders of at least 30% in aggregate principal amount of the then outstanding series of Senior Notes due 2027 may declare all the Senior Notes due 2027 of such series to be due and payable immediately.

The foregoing is a summary of the Senior Notes due 2027 and the related indentures, does not purport to be complete, and is qualified in its entirety by reference to the full texts thereof. Grace has filed the full text of such documents with the SEC, which are readily available on the internet at www.sec.gov.

Certain of Grace’s assets and liabilities are reported at fair value on a gross basis. ASC 820 “Fair Value Measurements and Disclosures” defines fair value as the value that would be received at the measurement date in the principal or “most advantageous” market. Grace uses principal market data, whenever available, to value assets and liabilities that are required to be reported at fair value.

Grace has identified the following financial assets and liabilities that are subject to the fair value analysis required by ASC 820:     

Fair Value of Debt and Other Financial Instruments    Debt payable is recorded at carrying value. Fair value is determined based on Level 2 inputs, including expected future cash flows (discounted at market interest rates), estimated current market prices and quotes from financial institutions.

---

At September 30, 2020, and December 31, 2019, the carrying amounts, net of unamortized debt issuance costs and discounts (see Note 3), and fair values of Grace’s debt were as follows:

	September 30, 2020								December 31, 2019
(In millions)	Carrying Amount				Fair Value				Carrying Amount				Fair Value
2018 U.S. dollar term loan	$	924.7			$	906.6			$	930.9			$	938.1
Senior notes due 2027	739.5				764.7				—				—
Senior notes due 2024	298.0				317.4				297.6				329.2
Senior notes due 2021	—				—				697.3				727.1
Other borrowings	42.2				42.2				54.6				54.6
Total debt	$	2,004.4			$	2,030.9			$	1,980.4			$	2,049.0

At September 30, 2020, the recorded values of other financial instruments such as cash equivalents and trade receivables and payables approximated their fair values, based on the short-term maturities and floating rate characteristics of these instruments.

Currency Derivatives    Because Grace operates and/or sells to customers in over 60 countries and in over 30 currencies, its results are exposed to fluctuations in currency exchange rates. Grace seeks to minimize exposure to these fluctuations by matching sales with expenditures in the same currencies, but it is not always possible to do so. From time to time, Grace uses financial instruments such as currency forward contracts, options, swaps, or combinations thereof to reduce the risk of certain specific transactions. However, Grace does not have a policy of hedging all exposures, because management does not believe that such a level of hedging would be cost-effective. Forward contracts with maturities of not more than 36 months are used and designated as cash flow hedges of forecasted repayments of intercompany loans. The effective portion of gains and losses on these currency hedges is recorded in “accumulated other comprehensive income (loss)” and reclassified into “other (income) expense, net” to offset the remeasurement of the underlying hedged loans. Forward points are excluded from the assessment of effectiveness and amortized to income on a systematic basis.

Grace also enters into foreign currency forward contracts and swaps to hedge a portion of its net outstanding monetary assets and liabilities. These forward contracts and swaps are not designated as hedging instruments under applicable accounting guidance, and therefore all changes in their fair value are recorded in “other (income) expense, net,” in the Consolidated Statements of Operations. These forward contracts and swaps are intended to offset the foreign currency gains or losses associated with the underlying monetary assets and liabilities.

The valuation of Grace’s currency exchange rate forward contracts and swaps is determined using an income approach. Inputs used to value currency exchange rate forward contracts and swaps consist of: (1) spot rates, which are quoted by various financial institutions; (2) forward points, which are primarily affected by changes in interest rates; and (3) discount rates used to present value future cash flows, which are based on the London Interbank Offered Rate (LIBOR) curve or overnight indexed swap rates. Total notional amounts for forward contracts and swaps outstanding as of September 30, 2020, were $71.6 million.

Cross-Currency Swap Agreements    Grace uses cross-currency swaps designated as cash flow hedges to manage fluctuations in currency exchange rates and interest rates on variable rate debt. Gains and losses on these cash flow hedges are recorded in “accumulated other comprehensive income (loss)” and reclassified into “other (income) expense, net” and “interest expense and related financing costs” during the hedged period.

In connection with the 2018 U.S. dollar term loan, Grace entered into cross-currency swaps beginning on November 5, 2018, and maturing on March 31, 2023, to synthetically convert $600.0 million of U.S. dollar-denominated floating rate debt into €525.9 million of euro-denominated debt fixed at 1.785%. The valuation of these cross-currency swaps is determined using an income approach, using LIBOR and EURIBOR (Euro Interbank Offered Rate) swap curves, currency basis spreads, and euro/U.S. dollar exchange rates.

---

Debt and Interest Rate Swap Agreements    Grace uses interest rate swaps designated as cash flow hedges to manage fluctuations in interest rates on variable rate debt. The effective portion of gains and losses on these interest rate cash flow hedges is recorded in “accumulated other comprehensive income (loss)” and reclassified into “interest expense and related financing costs” during the hedged interest period.

In connection with the 2018 U.S. dollar term loan, Grace entered into interest rate swaps beginning on April 3, 2018, and maturing on March 31, 2023, fixing the LIBOR component of the interest on $100.0 million of term debt at 2.775%. The valuation of these interest rate swaps is determined using an income approach, using prevailing market interest rates and discount rates to present value future cash flows based on the forward LIBOR yield curves. Credit risk is also incorporated into derivative valuations.

Net Investment Hedges    Grace uses cross-currency swaps as derivative hedging instruments in certain net investment hedges of its non-U.S. subsidiaries. The gains and losses attributable to these net investment hedges, adjusted for the impact of excluded components, are recorded net of tax to “currency translation adjustments” within “accumulated other comprehensive income (loss)” to offset the change in the carrying value of the net investment being hedged. Recognition in earnings of amounts previously recorded to “currency translation adjustments” is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. Changes in the fair value of the hedging instrument related to time value, which are excluded from the assessment of hedge effectiveness, are recorded directly to interest expense on a systematic basis. These gains were $0.6 million and $2.3 million for the three and nine months ended September 30, 2020, and $0.9 million and $2.5 million for the corresponding prior-year periods. At September 30, 2020, the notional amount of €170.0 million of Grace’s cross-currency swaps was designated as a hedging instrument of its net investment in its European subsidiaries.

Credit Risk    Grace is exposed to credit risk in its trade accounts receivable. Grace’s credit evaluation policies mitigate credit risk exposures, and it has a history of minimal credit losses. Grace does not generally require collateral for its trade accounts receivable, but may require a bank letter of credit in certain instances, particularly when selling to customers in cash-restricted countries.

Grace may also be exposed to credit risk in its derivatives contracts. Grace monitors counterparty credit risk and currently does not anticipate nonperformance by counterparties to its derivatives. Grace’s derivative contracts are with internationally recognized commercial financial institutions.

Grace’s effective tax rates for the nine months ended September 30, 2020 and 2019, were (26.0)% and 26.9%, respectively.

Grace’s effective tax rate for the nine months ended September 30, 2020, was negative primarily due to the net benefit of the Global Intangible Low-Taxed Income (“GILTI”) High-Tax Exclusion (“HTE”) in the U.S. and was partially offset by income taxed in jurisdictions with higher statutory tax rates than the U.S., recognition of certain state valuation allowances, and the expiration of unexercised stock options, as well as the impact of a write-off of previously capitalized engineering and site costs.

On July 20, 2020, the U.S. Treasury Department released final regulations related to the GILTI HTE. Grace has recognized a benefit in the three and nine months ended September 30, 2020, associated with the GILTI HTE regulations that resulted in a retroactive tax benefit related to 2018 and 2019 of approximately $23 million.

Grace’s effective tax rate for the nine months ended September 30, 2019, was higher than the U.S. federal statutory rate primarily due to income taxed in jurisdictions with higher statutory tax rates than the U.S. and the net impact of the GILTI tax in the U.S., partially offset by discrete benefits related to changes in tax law and to the favorable resolution of uncertain tax positions.

As of September 30, 2020, and December 31, 2019, Grace had $315.5 million and $302.5 million, respectively, in federal tax credit carryforwards before unrecognized tax benefits.

Plan Contributions and Funding    Grace intends to continue to satisfy its funding obligations under the U.S. qualified pension plans and to comply with all of the requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”). For ERISA purposes, funded status is calculated on a different basis than under U.S. GAAP.

Grace intends to continue to fund non-U.S. pension plans based on applicable legal requirements and actuarial recommendations.

Defined Contribution Retirement Plans    Grace sponsors a defined contribution retirement plan for its employees in the United States. This plan is qualified under section 401(k) of the U.S. tax code. Currently, Grace contributes an amount equal to 100% of employee contributions, up to 6% of an individual employee’s salary or wages. Grace’s cost related to this benefit plan for the three and nine months ended September 30, 2020, was

---

$3.7 million and $10.6 million compared with $3.5 million and $10.4 million for the corresponding prior-year periods.

U.S. salaried employees and certain U.S. hourly employees hired on or after January 1, 2017, and employees in Germany hired on or after January 1, 2016, participate in enhanced defined contribution plans instead of defined benefit pension plans. For the U.S. plan, Grace contributes 4% of an individual employee’s salary or wages. For the German plan, contributions vary based on the individual employee’s contributions and other factors. Grace’s cost related to these enhanced defined contribution plans established in the U.S. and Germany for the three and nine months ended September 30, 2020, was $1.0 million and $3.1 million compared with $0.8 million and $2.3 million for the corresponding prior-year periods.

Legacy Matters

Over the years, Grace operated numerous types of businesses that are no longer part of its ongoing operations. As Grace divested or otherwise ceased operating these businesses, it retained certain liabilities and obligations, which Grace refers to as legacy liabilities. These liabilities include product, environmental and other liabilities. Although the outcome of each of the matters discussed below cannot be predicted with certainty, Grace has assessed its risk and has recorded estimated liabilities as required under U.S. GAAP.

Legacy Product Liabilities    Grace emerged from an asbestos-related Chapter 11 bankruptcy on February 3, 2014 (the “Effective Date”). Under its plan of reorganization, all pending and future asbestos-related claims are channeled for resolution to either a personal injury trust (the “PI Trust”) or a property damage trust (the “PD Trust”). The trusts are the sole recourse for holders of asbestos-related claims. The channeling injunctions issued by the bankruptcy court prohibit holders of asbestos-related claims from asserting such claims directly against Grace.

Grace has satisfied all of its financial obligations to the PI Trust. Grace has contingent financial obligations remaining to the PD Trust. With respect to property damage claims related to Grace’s former Zonolite attic insulation product (“ZAI PD Claims”), the PD Trust was funded with $49.4 million (net of $15 million of attorneys’ fees) to pay claims and expenses. Grace is also obligated to make up to 10 contingent deferred payments of $8 million per year to the PD Trust during the 20-year period beginning on the fifth anniversary of the Effective Date, with each such payment due only if the assets of the PD Trust in respect of ZAI PD Claims fall below $10 million during the preceding year. As of September 30, 2020, the PD Trust has paid out approximately $36 million in ZAI PD Claims and expenses, leaving a balance of approximately $19 million, including the benefit of net investment gains.

Due to the limited claims history, the unique nature of this product, and the uncertainty of future claims patterns, an actuarial analysis was completed to estimate the range of possible future payments. The analysis was conducted by a third-party actuarial firm directed by Grace and using historical claims data provided by the ZAI trustee. Certain key assumptions employed in the analysis were (1) projections of the future number of filed claims, assuming a percentage increase in claims during earlier years and annual decreases in later years; (2) application of historical percentages of claims closed with indemnity payment compared to total closed claims, applied on a regional basis; and (3) application of the average claim payout, which reflects the average indemnity cost per claim closing with payment. As a result of the analysis and taking into account the relative uncertainty of future claims activity, Grace determined that contingent funding obligations beyond 2024 are not reasonably

---

estimable. Grace estimates that the reasonable range of payments over the period of 2020 to 2024 is expected to be between $16 million and $24 million and projects that the first payment could be due in 2022. In the 2019 fourth quarter, Grace recorded a $24.0 million liability related to probable future obligations to fund the PD Trust for ZAI PD Claims. Grace’s maximum financial obligation over the next 19 years is $80.0 million, and no single year’s obligation can exceed $8.0 million.

With respect to other asbestos property damage claims (“Other PD Claims”), claims unresolved as of the Effective Date are to be litigated in the bankruptcy court and any future claims are to be litigated in a federal district court, in each case pursuant to procedures approved by the bankruptcy court. To the extent any such Other PD Claims are determined to be allowed claims, they are to be paid in cash by the PD Trust. Grace is obligated to make a payment to the PD Trust every six months in the amount of any Other PD Claims allowed during the preceding six months plus interest (if applicable) and the amount of PD Trust expenses for the preceding six months (the “PD Obligation”). Grace has not paid any Other PD Claims since emergence. Annual expenses have been approximately $0.2 million per year. The aggregate amount to be paid under the PD Obligation is not capped, and Grace may be obligated to make additional payments to the PD Trust in respect of the PD Obligation. Grace has accrued for those unresolved Other PD Claims that it believes are probable and estimable. Grace has not accrued for other unresolved or unasserted Other PD Claims as it does not believe that payment is probable.

All payments to the PD Trust required after the Effective Date are secured by the Company’s obligation to issue 77,372,257 shares of Company common stock to the PD Trust in the event of default, subject to customary anti-dilution provisions.

This summary of the commitments and contingencies related to the Chapter 11 proceeding does not purport to be complete and is qualified in its entirety by reference to the plan of reorganization and the exhibits and documents related thereto, which have been filed with the SEC and are readily available on the internet at www.sec.gov.

Legacy Environmental Liabilities    Grace is subject to loss contingencies resulting from extensive and evolving federal, state, local and foreign environmental laws and regulations relating to its manufacturing operations. Grace has procedures in place to minimize such contingencies; nevertheless, it has liabilities associated with past operations and additional claims may arise in the future, which may be material. To address its legacy liabilities, Grace accrues for anticipated costs of response efforts where an assessment has indicated that a probable liability has been incurred and the cost can be reasonably estimated. These accruals do not take into account any discounting for the time value of money.

Grace’s environmental liabilities are reassessed regularly and adjusted when circumstances become better defined or response efforts and their costs can be better estimated, typically as a matter moves through the life-cycle of environmental investigation and remediation. These liabilities are evaluated based on currently available information relating to the nature and extent of contamination, risk assessments, feasibility of response actions, and apportionment amongst other potentially responsible parties, all evaluated in light of prior experience.

At September 30, 2020, Grace’s estimated liability for legacy environmental response costs totaled $110.7 million, compared with $115.3 million at December 31, 2019, and was included in “other current liabilities” and “other liabilities” in the Consolidated Balance Sheets. These amounts are based on agreements in place or on Grace’s estimate of costs where no formal remediation plan or agreement to pay exists, yet there is sufficient information to estimate response costs.

Vermiculite-Related Matters

Grace purchased a vermiculite mine in Libby, Montana, in 1963 and operated it until 1990. Vermiculite concentrate from the Libby mine was used in the manufacture of attic insulation and other products. Some of the vermiculite ore contained naturally occurring asbestos.

Grace is engaged with the U.S. Environmental Protection Agency (the “EPA”) and other federal, state, and local governmental agencies in a remedial investigation and feasibility study (“RI/FS”) of the Libby mine and the

---

surrounding area, known as Operable Unit 3 (“OU3”). The RI/FS will study the specific areas within OU3 requiring remediation and will identify possible remedial action alternatives. Possible remedial actions within OU3 are wide-ranging, from institutional controls such as land use restrictions, to more active measures involving soil removal, containment projects, or other protective measures.

As part of the RI/FS process, Grace contracted an engineering and consulting firm to develop a range of possible remedial alternatives and associated cost estimates for OU3. Based on this work, Grace recorded a pre-tax charge of $70.0 million in the 2018 third quarter for the estimated costs of remediation of OU3. Grace believes that this amount should provide for a protective remedy meeting the statutory requirements of the Comprehensive Environmental Response, Compensation, and Liability Act.

The estimated costs of remediation are preliminary and consist of several components, each of which may vary significantly as the remedial alternatives are further developed. It is reasonably possible that the ultimate costs of remediation could range between $30 million and $170 million. Grace is working closely with the EPA, and the ultimate remedy will be determined by the EPA after the RI/FS is finalized. Such remedy will be set forth in a Record of Decision (“ROD”) that is currently expected to be issued by the EPA in 2023. Costs associated with the more active remedial alternatives would be expected to be incurred over a decade or more. Grace will reevaluate its estimated liability as remedial alternatives evolve based on further work by the engineering and consulting firm and discussions with the EPA as the RI/FS process moves toward a ROD. Technical memoranda expected prior to the issuance of the ROD may provide insight into the likely remedial alternatives ultimately selected, allowing Grace to update its cost of remediation estimate. Depending on the remedial alternatives that the EPA selects in the ROD, the total cost of remediating OU3 may exceed Grace’s current estimate by material amounts. The amounts set forth above do not include possible liability for natural resources damage. Based on ecological studies conducted by the EPA, Grace does not believe that natural resources damage has occurred. However, if a party were to be successful in asserting a natural resources damage claim, liability related to such obligation could be material.

Grace has cooperated with the EPA in investigating and remediating a number of formerly owned or operated sites that processed Libby vermiculite into finished products. Grace has recorded a liability for remaining expected response costs, including costs for EPA oversight and potential future site remediation, where a review has indicated that liability is probable and the cost is estimable. The EPA may commence additional investigations in the future at other sites that processed Libby vermiculite. Liability for unaccrued additional investigation and remediation costs is probable but not yet estimable, and could be material.

Grace’s estimated liability for response costs that are currently estimable for OU3 and vermiculite processing sites outside of Libby at September 30, 2020, and December 31, 2019, totaled $72.4 million and $76.0 million, respectively. It is possible that Grace’s ultimate liability for these vermiculite-related matters will exceed current estimates by material amounts.

Non-Vermiculite-Related Environmental Matters

At September 30, 2020, and December 31, 2019, Grace’s estimated legacy environmental liability for response costs at sites not related to its former vermiculite mining and processing activities totaled $38.3 million and $39.3 million, respectively. This liability relates to Grace’s former businesses or operations, including its share of liability at off-site disposal facilities. Grace’s estimated liability is based upon regulatory requirements and environmental conditions at each site. As Grace receives new information, its estimated liability may change materially.

Other Legacy Liabilities    Beginning in 1971, as part of implementing a wet milling process at the Libby, Montana, vermiculite mine, Grace constructed a dam at the mine property that now prevents vermiculite ore tailings from moving into nearby creeks and rivers. Ongoing operation of the dam is regulated by the Montana Department of Natural Resources and Conservation (“DNRC”). In April 2019, the DNRC renewed the permit necessary for operation of the dam. Grace is legally obligated to operate the dam and construct a new spillway in accordance with the latest permit conditions.

---

Construction of the new dam spillway at the former mine site is a key element of Grace’s overall remediation strategy. The project includes both an upper spillway and a lower spillway that are being managed as two separate projects with different engineering design and construction timelines. In 2019, Grace contracted a third-party engineering and consulting firm to develop an initial range of cost estimates for the total project. Based on this work, Grace recorded a pre-tax liability of $68.0 million in 2019 for the estimated costs of the project. These costs were preliminary and subject to change as new information becomes available, including defining the final scope of the projects through the contract bidding process. During the three months ended September 30, 2020, Grace completed a review of contractor bids for the replacement of the upper spillway. Based on a current assessment of the project requirements, Grace increased its cost estimate for this portion of the project by $27.0 million, bringing the estimate for the total project to $95.0 million. Regarding the lower spillway, final engineering will be completed and submitted to the state of Montana for design approval in 2021, after which Grace will seek contract bids for this portion of the project. Grace believes it is reasonably possible that the ultimate costs of the two spillway projects could range between $80 million and $120 million. As Grace receives new information, its estimated liability may change materially. Construction of the spillways will begin in 2021 and is expected to take three to four years.

Commercial and Financial Commitments and Contingencies

Purchase Commitments    Grace uses purchase commitments to ensure supply and to minimize the volatility of major components of direct manufacturing costs including natural gas, certain metals, rare earths, and other materials. Such commitments are for quantities that Grace fully expects to use in its normal operations.

Guarantees and Indemnification Obligations    Grace is a party to many contracts containing guarantees and indemnification obligations. These contracts primarily consist of:

•	Product warranties with respect to certain products sold to customers in the ordinary course of business. These warranties typically provide that products will conform to specifications. Grace accrues a warranty liability on a transaction-specific basis depending on the individual facts and circumstances related to each sale.

•	Performance guarantees offered to customers under certain licensing arrangements. Grace has not established a liability for these arrangements based on past performance.

•	Licenses of intellectual property by Grace to third parties in which Grace has agreed to indemnify the licensee against third party infringement claims.

•	Contracts providing for the sale or spin-off of a former business unit or product line in which Grace has agreed to indemnify the buyer or resulting entity against certain liabilities related to activities prior to the closing of the transaction, including environmental, tax, and employee liabilities.

•	Indemnification obligations of Grace as a tenant of real property leases; and guarantees of real property lease obligations of third parties, typically arising out of (a) leases entered into by former subsidiaries of Grace, or (b) the assignment or sublease of a lease by Grace to a third party.

Financial Assurances    Financial assurances have been established for a variety of purposes, including insurance and environmental matters, trade-related commitments and other matters. As of September 30, 2020, Grace had gross financial assurances issued and outstanding of $140.7 million, composed of $79.6 million of surety bonds issued by various insurance companies and $61.1 million of standby letters of credit and other financial assurances issued by various banks.

Restructuring Expenses    Restructuring activity in the three and nine months ended September 30, 2020, primarily related to an increase in estimated contractual costs related to a 2018 plant exit. Restructuring activity in the three and nine months ended September 30, 2019, primarily related to severance costs pertaining to the idling of our methanol-to-olefins (“MTO”) manufacturing facility. These costs are included in “restructuring and

---

repositioning expenses” in the Consolidated Statements of Operations, and are not included in segment operating income.

The following table presents restructuring expenses by reportable segment for the three and nine months ended September 30, 2020 and 2019.

Substantially all costs related to the restructuring programs are expected to be paid by June 30, 2023, but could be paid earlier subject to negotiations around certain plant exit costs.

Repositioning Expenses    Repositioning expenses for the three and nine months ended September 30, 2020, were $2.5 million and $26.0 million, respectively, compared with $3.2 million and $8.9 million for the corresponding prior-year periods.

During the three months ended June 30, 2020, Grace implemented changes to its Refining Technologies manufacturing operations and global footprint to drive capital and operating efficiencies and to support global growth. Grace, in agreement with its local joint venture partner, discontinued the previously announced project to build a full-scale fluid catalytic cracking catalysts plant in the Middle East. As a result, repositioning expenses for the nine months ended September 30, 2020, included a pre-tax charge of $19.7 million ($2.5 million of which is attributable to Grace’s joint venture partner) to write off engineering and site costs.

Repositioning expenses for the three and nine months ended September 30, 2019, primarily related to a multi-year program to transform manufacturing and business processes to extend Grace’s competitive advantages and improve its cost position.

During the three months ended September 30, 2020, Hurricane Laura caused severe and widespread damage to Lake Charles, Louisiana, and surrounding communities, including catastrophic damage to the regional power grid. The hurricane-related costs were primarily due to on-site power generation, incremental operations and logistics costs to supply customers during the outage, temporary housing and employee assistance, and property damage and clean-up. In addition to the amounts shown above, Grace’s equity in earnings from unconsolidated affiliate was reduced by $1.1 million due to hurricane-related costs incurred by the joint venture.

In July 2019, a North American FCC catalysts customer filed for bankruptcy protection after announcing it would not resume refinery operations following a fire in its refinery. Grace received $16.3 million during the six months ended June 30, 2020, under its business interruption insurance policy. Including the $8.0 million received in the 2019 fourth quarter, Grace received $24.3 million of insurance recoveries related to this event, reflecting approximately eight quarters of the impact of the incident on earnings. This claim has been fully resolved.

Contract Balances    Grace invoices customers for product sales once performance obligations have been satisfied, generally at the point of delivery, at which point payment becomes unconditional. Accordingly, Grace’s product sales contracts generally do not give rise to material contract assets or liabilities under ASC 606; however, from time to time certain customers may pay in advance, which results in a contract liability. In the technology licensing business, Grace typically invoices licensees at the time that contractual milestones are achieved. However, in respect of the milestone billings, Grace is frequently obligated to provide services in future periods, and this results in recording contract liabilities.

The following table presents Grace’s deferred revenue balances as of September 30, 2020, and December 31, 2019:

(In millions)	September 30, 2020				December 31, 2019
Current	$	35.9			$	35.0
Noncurrent	21.9				29.5
Total	$	57.8			$	64.5

Grace records deferred revenues when cash payments are received or due in advance of performance. The change in deferred revenue reflects cash payments from customers received or due in advance of satisfying performance obligations, offset by $6.8 million and $22.9 million of revenue recognized for the three and nine months ended September 30, 2020, respectively, that was included in the deferred revenue balance as of December 31, 2019.

The noncurrent portion of deferred revenue will be recognized as performance obligations under the technology licensing agreements are satisfied, which is expected to be over the next four years.

Remaining performance obligations represent the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). The aggregate amount of the transaction price allocated to remaining performance obligations for such contracts with a duration of more than one year was approximately $150 million as of September 30, 2020, and includes certain amounts reported as deferred revenue above. In accordance with the available practical expedient, Grace does not disclose information about remaining performance obligations that have original expected durations of one year or less, which generally relate to customer prepayments on product sales and are generally satisfied in less than one year. Grace expects to recognize revenue related to remaining performance obligations over several years, as follows:

---

Year		Approximate percentage of revenue related to remaining performance obligations recognized
Remainder of 2020		6	%
2021		26	%
2022		21	%
2023		15	%
Thereafter through 2030		32	%

For the three and nine months ended September 30, 2020 and 2019, revenue recognized from performance obligations related to prior periods was not material. Grace has not capitalized any costs to obtain or fulfill contracts with customers under ASC 606. No material impairment losses have been recognized on any receivables or contract assets arising from contracts with customers.

Grace is a global producer of specialty chemicals and specialty materials. Grace’s two reportable business segments are Grace Catalysts Technologies and Grace Materials Technologies. Grace Catalysts Technologies includes catalysts and related products and technologies used in petrochemical, refining, and other chemical manufacturing applications. Advanced Refining Technologies LLC (“ART”), Grace’s joint venture with Chevron U.S.A. Inc. (“Chevron”), is managed in this segment. (See Note 15.) Grace Catalysts Technologies comprises two operating segments, Grace Refining Technologies and Grace Specialty Catalysts, which are aggregated into one reportable segment based upon similar economic characteristics, the nature of the products and production processes, type and class of customer, and channels of distribution. Grace Materials Technologies includes specialty materials, including silica-based and silica-alumina-based materials, used in pharma/consumer, coatings, and chemical process applications. The table below presents information related to Grace’s reportable segments. Only those corporate expenses directly related to the reportable segments are allocated for reporting purposes. All remaining corporate items are reported separately and labeled as such.

Grace excludes defined benefit pension expense from the calculation of segment operating income. Grace believes that the exclusion of defined benefit pension expense provides a better indicator of its reportable segment performance as defined benefit pension expense is not managed at a reportable segment level.

Grace defines Adjusted EBIT to be net income attributable to W. R. Grace & Co. shareholders adjusted for interest income and expense; income taxes; costs related to legacy matters; restructuring and repositioning expenses and asset impairments; pension costs other than service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; gains and losses on sales or exits of businesses, product lines, and certain other investments; third-party acquisition-related costs and the amortization of acquired inventory fair value adjustment; gains and losses on modification or extinguishment of debt; the effects of these items on equity in earnings of unconsolidated affiliate; and certain other items that are not representative of underlying trends.

Unconsolidated Affiliate    Grace accounts for its 50% ownership interest in ART, its joint venture with Chevron, using the equity method of accounting. Grace’s investment in ART amounted to $167.4 million and $181.9 million as of September 30, 2020, and December 31, 2019, respectively. ART is a private, limited liability company, taxed as a partnership, and accordingly does not have a quoted market price available. During the three months ended September 30, 2020, Grace received a $10.0 million dividend from ART, and the Consolidated Balance Sheet as of September 30, 2020, includes an additional $10.0 million dividend receivable from ART to be paid in the 2020 fourth quarter.

Grace and ART transact business on a regular basis and maintain several agreements in order to operate the joint venture. These agreements and the resulting transactions are treated as related party activities with an unconsolidated affiliate. Product manufactured by Grace for ART is accounted for on a net basis, with a mark-up, which reduces “cost of goods sold” in the Consolidated Statements of Operations. Grace also receives reimbursement from ART for fixed costs; research and development; selling, general and administrative services; and depreciation. Grace records reimbursements against the respective line items on Grace’s Consolidated Statements of Operations. The table below presents summary financial data related to transactions between Grace and ART.

The other current asset as of September 30, 2020, in the table above represents the dividend receivable from ART to be paid in the 2020 fourth quarter. The current asset and current liability as of December 31, 2019, represented spending related to a residue hydroprocessing catalyst production plant that has been constructed in Lake Charles, Louisiana. Grace managed the design and construction of the plant, and the asset was included in “other current assets” in Grace’s Consolidated Balance Sheets until commissioning and start-up activities were completed. Grace had likewise recorded a liability for the transfer of the asset to ART upon completion, included in “other current liabilities” in the Consolidated Balance Sheets. Grace transferred the asset to ART in the 2020 third quarter.

Grace and ART maintain an agreement whereby ART loans Grace funds for maintenance capital expenditures at manufacturing facilities used to produce catalysts for ART. Grace makes principal and interest payments on the loans on a monthly basis. These unsecured loans have repayment terms of up to eight years, unless earlier repayment is demanded by ART. The loans bear interest at the three-month LIBOR plus 1.25%.

Grace and Chevron provide lines of credit in the amount of $15.0 million each at a commitment fee of 0.1% of the credit amount. These agreements have been approved by the ART Executive Committee for renewal until February 2021. No amounts were outstanding at September 30, 2020, or December 31, 2019.

Rive Technology, Inc. On June 17, 2019, Grace completed the acquisition of the business and assets of Rive Technology, Inc. for $22.8 million, with an additional $2.0 million holdback payment remitted in the three months ended September 30, 2020. The business is included in the Refining Technologies operating segment of the Catalysts Technologies reportable segment. The acquisition included Rive’s MOLECULAR HIGHWAY^® zeolite technology for catalytic processes, which allows Grace to offer a broader spectrum of products for converting crude oil to petrochemical feedstocks.

•	Specialty catalysts demand to improve sequentially, with polyolefin catalyst demand improving in all regions and non-durable end markets continuing to show strength, particularly in hygiene and packaging applications;

•	FCC catalysts demand to improve sequentially, as the demand for transportation fuels has stabilized and we are seeing recovery from 2020 second quarter lows. Transportation fuel demand and refinery utilization still remain below normal levels for the industry and the effects of the pandemic are expected to continue to be a headwind until demand more fully recovers; and

•	Materials Technologies demand to improve sequentially with continued strength in pharma/consumer end markets driven by consumers’ focus on health and personal care needs, higher demand in coatings end markets, and ongoing recovery in wood/coil applications.

•	Event-related costs occurring in the third quarter were approximately $12 million. The costs, included in Catalysts Technologies segment operating income, were primarily related to on-site power generation, incremental operations and logistics costs to supply customers during the outage, temporary housing and employee assistance, and property damage and clean-up.

•	The total estimated hurricane-related costs for the full year are expected to be $18 to $20 million.
