CONSOLIDATED FINANCIAL INFORMATION
CONSOLIDATED FINANCIAL INFORMATION	1. CONSOLIDATED FINANCIAL INFORMATION ​ The unaudited consolidated financial information for the second quarter ended June 30, 2022 and 2021 reflects, in the opinion of management, all adjustments necessary for a fair statement of the financial position, results of operations, comprehensive income, equity and cash flows of Ecolab Inc. ("Ecolab" or "the Company") for the interim periods presented. Any adjustments consist of normal recurring items. ​ In March 2020, coronavirus 2019 (“COVID-19”) was declared a pandemic by the World Health Organization. As the impact of the pandemic continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require judgment. These estimates and assumptions may change in future periods and will be recognized in the consolidated financial information as new events occur and additional information becomes known. To the extent actual results differ materially from those estimates and assumptions, the Company’s future financial statements could be affected. ​ The financial results for any interim period are not necessarily indicative of results for the full year. The consolidated balance sheet data as of December 31, 2021 was derived from the audited consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited consolidated financial information should be read in conjunction with the consolidated financial statements and notes thereto incorporated in the Company's Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission (“SEC”) on February 25, 2022. ​ With respect to the unaudited financial information of the Company for the second quarter ended June 30, 2022 and 2021 included in this Form 10-Q, PricewaterhouseCoopers LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. Their separate report dated August 4, 2022 appearing herein states that they did not audit and they do not express an opinion on that unaudited financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933, as amended (the "Act"), for their report on the unaudited financial information because that report is not a "report" or a "part" of a registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Act. ​

These activities have been included as a component of cost of sales and special (gains) and charges on the Consolidated Statements of Income. Restructuring liabilities have been classified as a component of other current and other noncurrent liabilities on the Consolidated Balance Sheets. ​ Institutional Advancement Program ​ The Company approved a restructuring plan in 2020 focused on the Institutional business (“the Institutional Plan”) which is intended to enhance our Institutional sales and service structure and allow the sales team to capture share and penetration while maximizing service effectiveness by leveraging our ongoing investments in digital technology. In February 2021, the Company expanded the Institutional Plan, and expect that these restructuring charges will be completed by 2023, with total anticipated costs of $65 million ( $50 million after tax). The remaining costs are expected to be primarily cash expenditures for severance and non-cash costs related to equipment disposals. Actual costs may vary from these estimates depending on actions taken. ​ Certain activities contemplated in this Institutional Plan were previously approved in 2020 and included as part of Accelerate 2020. These activities were reclassified to the Institutional Plan. During the second quarter of 2022 and 2021, the Company recorded restructuring charges of $0.7 million ( $0.6 million after tax) and $2.2 million ( $1.6 million after tax), respectively, and in the first six months of 2022 and 2021 $2.1 million ( $1.6 million after tax) and $8.1 million ( $6.1 million after tax), respectively, primarily related to severance, disposals of equipment and office closures. The Company has recorded $49.9 million ( $38.2 million after tax) of cumulative restructuring charges under the Institutional Plan. The liability related to the Institutional Plan was $2.4 million as of June 30, 2022 and is expected to be paid over a period of a few months to several quarters and will continue to be funded from operating activities. ​ ​ Restructuring activity related to the Institutional Plan since inception of the underlying actions includes the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Employee ​ ​ ​ ​ ​ ​ ​ Termination ​ Asset ​ ​ ​ ​ ​ ​ (millions) Costs Disposals Other Total 2020-2021 Activity ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recorded expense (income) and accrual ​ ​ $23.8 ​ ​ ​ $8.5 ​ ​ ​ $15.5 ​ ​ ​ $47.8 ​ Net cash payments ​ (19.9) ​ ​ ​ - ​ ​ ​ (14.3) ​ ​ ​ (34.2) ​ Non-cash net charges ​ - ​ ​ ​ (8.5) ​ ​ ​ - ​ ​ ​ (8.5) ​ Restructuring liability, December 31, 2021 ​ 3.9 ​ ​ ​ - ​ ​ ​ 1.2 ​ ​ ​ 5.1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 Activity ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recorded expense (income) and accrual 0.1 ​ ​ ​ 1.4 ​ ​ ​ 0.6 ​ ​ 2.1 ​ Net cash payments (3.3) ​ ​ ​ - ​ ​ ​ (0.1) ​ ​ (3.4) ​ Non-cash net charges - ​ ​ ​ (1.4) ​ ​ ​ - ​ ​ (1.4) ​ Restructuring liability, June 30, 2022 ​ ​ $0.7 ​ ​ ​ $- ​ ​ ​ $1.7 ​ ​ ​ $2.4 ​ ​ Accelerate 2020 ​ During 2018, the Company formally commenced a restructuring plan Accelerate 2020 (“the Plan”), to leverage technology and system investments and organizational changes. The goals of the Plan are to further simplify and automate processes and tasks, reduce complexity and management layers, consolidate facilities and focus on key long-term growth areas by further leveraging technology and structural improvements. During 2020, the Company expanded the Plan for additional costs and savings to further leverage the technology and structural improvements. Following the establishment of the separate Institutional Plan, the Company now expects that the restructuring activities will be completed by the end of 2022, with total anticipated costs of $255 million ( $195 million after tax) when revised for continuing operations. The remaining costs are expected to be primarily cash expenditures for severance costs and some facility closure costs relating to team reorganizations. Actual costs may vary from these estimates depending on actions taken. ​ The Company recorded restructuring charges (gains) of $0.1 million ( $0.1 million after tax) and ($0.3) million ( $0.2 million after tax) in the second quarter of 2022 and 2021, respectively, and $0.4 million ( $0.2 million after tax) and $1.4 million ( $1.6 million after tax) in the first six months of 2022 and 2021, respectively.

GOODWILL AND OTHER INTANGIBLE ASSETS
GOODWILL AND OTHER INTANGIBLE ASSETS	6. GOODWILL AND OTHER INTANGIBLE ASSETS ​ Goodwill ​ Goodwill arises from the Company’s acquisitions and represents the excess of the fair value of the purchase consideration exchanged over the fair value of net assets acquired. The Company’s reporting units are largely its operating segments. Following the acquisition of Purolite on December 1, 2021, our Life Sciences Operating Segment consists of the Purolite and Global Life Sciences Reporting Units. The Company assesses goodwill for impairment on an annual basis during the second quarter. If circumstances change or events occur that demonstrate it is more likely than not that the carrying amount of a reporting unit exceeds its fair value, the Company completes an interim goodwill assessment of that reporting unit prior to the next annual assessment. If the results of an annual or interim goodwill assessment demonstrate the carrying amount of a reporting unit is greater than its fair value, the Company will recognize an impairment loss for the amount by which the reporting unit’s carrying amount exceeds its fair value, but not to exceed the carrying amount of goodwill assigned to that reporting unit. ​ During the second quarter of 2022, the Company completed its annual goodwill impairment assessment for eleven of its twelve reporting units using discounted cash flow analyses that incorporated assumptions regarding future growth rates, terminal values and discount rates. The Company’s goodwill impairment assessments for 2022 indicated the estimated fair values of each of these eleven reporting units exceeded the carrying amounts of the respective reporting unit by a significant margin. Given the recent acquisition of Purolite, the Company’s annual goodwill impairment assessment of the Purolite Reporting Unit was qualitative in nature and considered information regarding its operations, financial performance and the macroeconomic environment. After weighting both positive and negative information, it is more likely than not that the fair value of the Purolite Reporting Unit exceeds its carrying amount. There has been no impairment of goodwill in any of the periods presented. ​ The changes in the carrying amount of goodwill for each of the Company's reportable segments during the six months ended June 30, 2022 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Global ​ Global ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Global ​ Institutional ​ Healthcare & ​ ​ ​ ​ ​ ​ ​ ​ (millions) Industrial & Specialty Life Sciences ​ Other Total ​ December 31, 2021 ​ ​ $4,270.1 ​ ​ $576.5 ​ ​ $2,974.2 ​ ​ $243.1 ​ ​ $8,063.9 ​ ​ Prior year business combinations (a) ​ ​ 2.1 ​ ​ - ​ ​ 17.8 ​ ​ - ​ ​ 19.9 ​ ​ Effect of foreign currency translation ​ ​ (79.1) ​ ​ (5.6) ​ ​ (60.3) ​ ​ (2.9) ​ ​ (147.9) ​ ​ June 30, 2022 ​ ​ $4,193.1 ​ ​ $570.9 ​ ​ $2,931.7 ​ ​ $240.2 ​ ​ $7,935.9 ​ ​ ​ (a) Represents purchase accounting adjustments associated with 2021 acquisitions. ​ Other Intangible Assets ​ The Nalco trade name is the Company’s only indefinite-lived intangible asset, which is tested for impairment on an annual basis during the second quarter. During the second quarter of 2022, the Company completed its annual impairment assessment of the Nalco trade name using the relief from royalty discounted cash flow method, which incorporates assumptions regarding future sales projections, royalty rates and discount rates. The Company’s Nalco tradename impairment assessment for 2022 indicated the estimated fair value of the Nalco trade name exceeded its $1.2 billion carrying amount by a significant margin. There has been no impairment of the Nalco trade name intangible since it was acquired. ​ The Company’s intangible assets subject to amortization include customer relationships, trademarks, patents and other technology primarily acquired through business acquisitions. The fair value of intangible assets acquired in business acquisitions are estimated primarily using discounted cash flow valuation methods at the time of acquisition. Intangible assets are amortized on a straight-line basis over their estimated lives. Total amortization expense related to intangible assets during the second quarter of 2022 and 2021 was $78.7 million and $52.2 million, respectively. Total amortization expense related to intangible assets during the first six months of 2022 and 2021 was $158.2 and $116.7 million, respectively. Amortization expense related to intangible assets for the remaining six-month period of 2022 is expected to be approximately $159 million.

FAIR VALUE MEASUREMENTS ​ The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, contingent consideration obligations, commercial paper, notes payable, foreign currency forward contracts, interest rate swap agreements, cross-currency swap derivative contracts and long-term debt. ​ Fair value is defined as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. A hierarchy has been established for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring the most observable inputs be used when available. The hierarchy is broken down into three levels: ​ Level 1 - Inputs are quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities. Level 2 - Inputs include observable inputs other than quoted prices in active markets. Level 3 - Inputs are unobservable inputs for which there is little or no market data available. ​ The carrying amount and the estimated fair value for assets and liabilities measured on a recurring basis were: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 (millions) ​ Carrying ​ Fair Value Measurements ​ Amount Level 1 ​ Level 2 Level 3 Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts $153.0 ​ ​ ​ $- ​ ​ $153.0 ​ ​ $- ​ Cross-currency swap derivative contracts ​ ​ 58.4 ​ ​ ​ - ​ ​ ​ 58.4 ​ ​ ​ - ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ 44.9 ​ ​ ​ - ​ ​ ​ 44.9 ​ ​ ​ - ​ Interest rate swap agreements ​ ​ 119.3 ​ ​ ​ - ​ ​ ​ 119.3 ​ ​ ​ - ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 (millions) ​ Carrying ​ Fair Value Measurements ​ Amount Level 1 ​ Level 2 Level 3 Assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts $94.5 ​ ​ ​ $- ​ ​ $94.5 ​ ​ $- ​ Interest rate swap agreements ​ ​ 1.8 ​ ​ ​ - ​ ​ ​ 1.8 ​ ​ ​ - ​ Cross-currency swap derivative contracts ​ ​ 9.4 ​ ​ ​ - ​ ​ ​ 9.4 ​ ​ ​ - ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ 12.6 ​ ​ ​ - ​ ​ ​ 12.6 ​ ​ ​ - ​ Interest rate swap agreements ​ ​ 10.1 ​ ​ ​ - ​ ​ ​ 10.1 ​ ​ ​ - ​ Cross-currency swap derivative contracts ​ ​ 1.6 ​ ​ ​ - ​ ​ ​ 1.6 ​ ​ ​ - ​ ​ The carrying value of foreign currency forward contracts is at fair value, which is determined based on foreign currency exchange rates as of the balance sheet date and is classified within Level 2.

The cross-currency swap derivative contracts are used to partially hedge the Company’s net investments in foreign operations against adverse movements in exchange rates between the U.S. dollar and the Euro. The carrying value of the cross-currency swap derivative contracts are at fair value, which are determined based on the income approach with the relevant interest rates and foreign currency current exchange rates and forward curves as inputs as of the balance sheet date and is classified within Level 2. For purposes of fair value disclosure above, derivative values are presented gross. Further discussion of gross versus net presentation of the Company's derivatives is included within Note 8. ​ Contingent consideration obligations are recognized and measured at fair value at the acquisition date and thereafter until settlement or expiration. Contingent consideration is classified within Level 3 as the underlying fair value is determined using income-based valuation approaches appropriate for the terms and conditions of each respective contingent consideration. The consideration expected to be transferred is based on the Company’s expectations of various financial measures. The ultimate payment of contingent consideration could deviate from current estimates based on the actual results of these financial measures. Contingent consideration was not material to the Company’s consolidated financial statements. ​ The carrying values of accounts receivable, accounts payable, cash and cash equivalents, commercial paper and notes payable approximate fair value because of their short maturities and as such are classified within Level 1. ​ The fair value of long-term debt is based on quoted market prices for the same or similar debt instruments (classified as Level 2). The carrying amount, which includes adjustments related to the impact of interest rate swap agreements, premiums and discounts, and deferred debt issuance costs, and the estimated fair value of long-term debt, including current maturities, held by the Company were: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2022 ​ December 31, 2021 ​ ​ Carrying ​ Fair ​ Carrying ​ Fair ​ Amount Value Amount Value Long-term debt, including current maturities ​ ​ $8,170.3 ​ ​ ​ $7,669.0 ​ ​ ​ $8,349.7 ​ ​ ​ $9,085.3 ​

DERIVATIVES AND HEDGING TRANSACTIONS
DERIVATIVES AND HEDGING TRANSACTIONS	8. DERIVATIVES AND HEDGING TRANSACTIONS ​ The Company uses foreign currency forward contracts, interest rate swap agreements, cross-currency swap derivative contracts and foreign currency debt to manage risks associated with foreign currency exchange rates, interest rates and net investments in foreign operations. The Company does not hold derivative financial instruments of a speculative nature or for trading purposes. The Company records derivatives as assets and liabilities in the Consolidated Balance Sheets at fair value. Changes in fair value are recognized immediately in earnings unless the derivative qualifies and is designated as a hedge. Cash flows from derivatives are classified in the statement of cash flows in the same category as the cash flows from the items subject to designated hedge or undesignated (economic) hedge relationships. The Company evaluates hedge effectiveness at inception and on an ongoing basis. If a derivative is no longer expected to be effective, hedge accounting is discontinued. ​ The Company is exposed to credit risk in the event of nonperformance of counterparties for foreign currency forward exchange contracts and interest rate swap agreements. The Company monitors its exposure to credit risk by using credit approvals and credit limits and by selecting major global banks and financial institutions as counterparties. The Company does not anticipate nonperformance by any of these counterparties, and therefore, recording a valuation allowance against the Company’s derivative balance is not considered necessary. ​ Derivative Positions Summary ​ Certain of the Company’s derivative transactions are subject to master netting arrangements that allow the Company to net settle contracts with the same counterparties. These arrangements generally do not call for collateral and as of the applicable dates presented in the following table, no cash collateral had been received or pledged related to the underlying derivatives. ​ The respective net amounts are included in other current assets, other assets, other current liabilities and other liabilities on the Consolidated Balance Sheets. ​ The following table summarizes the gross fair value and the net value of the Company’s outstanding derivatives: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative Assets Derivative Liabilities ​ ​ ​ June 30 ​ December 31 ​ June 30 ​ December 31 ​ (millions) ​ 2022 ​ 2021 2022 ​ 2021 Derivatives designated as hedging instruments ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ ​ $100.6 ​ ​ ​ $44.7 ​ ​ $7.8 ​ ​ ​ $2.6 ​ Interest rate swap agreements ​ ​ ​ - ​ ​ ​ 1.8 ​ ​ 119.3 ​ ​ ​ 10.1 ​ Cross-currency swap derivative contracts ​ ​ ​ 58.4 ​ ​ ​ 9.4 ​ ​ - ​ ​ ​ 1.6 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivatives not designated as hedging instruments ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ ​ 52.4 ​ ​ ​ 49.8 ​ ​ 37.1 ​ ​ ​ 10.0 ​ Gross value of derivatives ​ ​ ​ 211.4 ​ ​ ​ 105.7 ​ ​ 164.2 ​ ​ ​ 24.3 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross amounts offset in the Consolidated Balance Sheets ​ ​ ​ (61.7) ​ ​ ​ (14.9) ​ ​ (61.7) ​ ​ ​ (14.9) ​ Net value of derivatives ​ ​ ​ $149.7 ​ ​ ​ $90.8 ​ ​ $102.5 ​ ​ ​ $9.4 ​ ​ The following table summarizes the notional values of the Company’s outstanding derivatives: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional Values ​ ​ ​ June 30 ​ ​ December 31 (millions) ​ 2022 ​ 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ $ 4,643 ​ ​ ​ $ 4,059 ​ Interest rate swap agreements ​ ​ 1,500 ​ ​ ​ 1,250 ​ Cross-currency swap derivative contracts ​ ​ 456 ​ ​ ​ 482 ​ ​ ​ Cash Flow Hedges ​ The Company utilizes foreign currency forward contracts to hedge the effect of foreign currency exchange rate fluctuations on forecasted foreign currency transactions, including inventory purchases and intercompany royalty, intercompany loans, management fee and other payments. These forward contracts are designated as cash flow hedges. The changes in fair value of these contracts are recorded in accumulated other comprehensive income (“AOCI”) until the hedged items affect earnings, at which time the gain or loss is reclassified into the same line item on the Consolidated Statements of Income as the underlying exposure being hedged. Cash flow hedged transactions impacting AOCI are forecasted to occur within the next two years . For forward contracts designated as hedges of foreign currency exchange rate risk associated with forecasted foreign currency transactions, the Company excludes the changes in fair value attributable to time value from the assessment of hedge effectiveness. The initial value of the excluded component (i.e., the forward points) is amortized on a straight-line basis over the life of the hedging instrument and recognized in the same line item on the Consolidated Statements of Income as the underlying exposure being hedged for intercompany loans. For all other cash flow hedge types, the forward points are marked-to-market monthly and recognized in the same line item on the Consolidated Statements of Income as the underlying exposure being hedged. The difference between fair value changes of the excluded component and the amount amortized on the Consolidated Statements of Income is recorded in AOCI. ​ Fair Value Hedges ​ The Company manages interest expense using a mix of fixed and floating rate debt. To help manage exposure to interest rate movements and to reduce borrowing costs, the Company may enter into interest rate swap agreements under which the Company agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed upon notional principal amount. The mark-to-market of these fair value hedges is recorded as gains or losses in interest (income) expense and is offset by the gain or loss of the underlying debt instrument, which also is recorded in interest (income) expense. These fair value hedges are highly effective and thus, there is no impact on earnings due to hedge ineffectiveness. ​ In April 2022, the Company entered into an interest rate swap agreement that converted $250 million of its 4.8% debt from a fixed interest rate to a floating interest rate. In aggregate, the Company has entered into a series of interest rate swap agreements to convert $1.5 billion of its debt from a fixed interest rate to a floating interest rate. These interest rate swap agreements are designated as fair value hedges. ​ The following amounts were recorded in the Consolidated Balance Sheets related to cumulative basis adjustments for fair value hedges: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying amount of the hedged liabilities ​ ​ Cumulative amount of the fair value hedging adjustment included in the carrying amount of the hedged liabilities ​ ​ ​ Second Quarter Ended ​ ​ Second Quarter Ended ​ Line item in which the hedged item is included ​ June 30 ​ ​ June 30 ​ (millions) 2022 ​ 2021 ​ 2022 ​ 2021 Long-term debt ​ ​ $1,376.4 ​ ​ ​ $249.2 ​ ​ ​ ($125.9) ​ ​ ​ ($1.1) ​ ​ Net Investment Hedges ​ The Company designates its outstanding €1,150 million ( $1,231 million at the end of the second quarter of 2022) senior notes (“Euronotes”) and related accrued interest as hedges of its Euro denominated exposures from the Company’s investments in certain of its Euro denominated functional currency subsidiaries. ​ The Company entered into a series of cross-currency swap derivative contracts maturing in 2030. The cross-currency swap derivative contracts are designated as net investment hedge of its Euro denominated exposures from the Company’s investments in certain of its Euro denominated functional currency subsidiaries. The cross-currency swap derivative contracts exchange fixed-rate payments in one currency for fixed-rate payments in another currency. As of June 30, 2022, the Company had €425 million ( $456 million) cross-currency swap derivative contracts outstanding as hedges of the Company’s net investment in foreign operations. The changes in the spot rate of these instruments are recorded in AOCI in stockholders’ equity, partially offsetting the foreign currency translation adjustment of the Company’s related net investment that is also recorded in AOCI. Any ineffective portions of net investment hedges are reclassified from AOCI into earnings during the period of change. The interest income or expense from these swaps are recorded in interest expense on the accompanying Consolidated Statements of Income consistent with the classification of interest expense attributable to the underlying debt. ​ ​ The revaluation gains and losses on the Euronotes and cross-currency swap derivative contracts, which are designated and effective as hedges of the Company’s net investments, have been included as a component of the cumulative translation adjustment account, and were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Second Quarter Ended ​ Six Months Ended ​ ​ ​ June 30 ​ June 30 (millions) 2022 ​ 2021 ​ 2022 ​ 2021 Revaluation gain (loss), net of tax: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Euronotes ​ ​ $42.5 ​ ​ ​ ($14.2) ​ ​ ​ $52.8 ​ ​ ​ ($26.4) ​ Cross-currency swap derivative contracts ​ ​ 28.9 ​ ​ ​ - ​ ​ ​ 37.5 ​ ​ ​ - ​ Total revaluation gain (loss), net of tax ​ ​ $71.4 ​ ​ ​ ($14.2) ​ ​ ​ $90.3 ​ ​ ​ ($26.4) ​ ​ Derivatives Not Designated as Hedging Instruments ​ The Company also uses foreign currency forward contracts to offset its exposure to the change in value of certain foreign currency denominated assets and liabilities held at foreign subsidiaries, primarily receivables and payables, which are remeasured at the end of each period. Although the contracts are effective economic hedges, they are not designated as accounting hedges. Therefore, changes in the value of these derivatives are recognized immediately in earnings, thereby offsetting the current earnings effect of the related foreign currency denominated assets and liabilities. ​ Effect of all Derivative Instruments on Income ​ The gain (loss) of all derivative instruments recognized in product and equipment cost of sales (“COS”), selling, general and administrative expenses (“SG&A”) and interest expense, net (“interest”) is summarized below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Second Quarter Ended ​ ​ ​ June 30 ​ ​ ​ 2022 ​ 2021 ​ (millions) ​ ​ COS ​ SG&A ​ Interest ​ ​ COS ​ SG&A ​ Interest ​ Gain (loss) on derivatives in cash flow hedging relationship: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount of gain (loss) reclassified from AOCI to income ​ ​ $0.8 ​ $38.2 ​ $- ​ ​ ​ ($3.6) ​ ($20.2) ​ $- ​ Amount excluded from the assessment of effectiveness recognized in earnings based on changes in fair value ​ ​ - ​ - ​ 3.9 ​ ​ ​ - ​ - ​ 5.7 ​ Interest rate swap agreements ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount of gain (loss) reclassified from AOCI to income ​ ​ - ​ - ​ (0.6) ​ ​ ​ - ​ - ​ (0.6) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gain (loss) on derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount of gain (loss) recognized in income ​ ​ - ​ 34.2 ​ - ​ ​ ​ - ​ 4.5 ​ - ​ Total gain (loss) of all derivative instruments ​ ​ $0.8 ​ $72.4 ​ $3.3 ​ ​ ​ ($3.6) ​ ($15.7) ​ $5.1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ ​ June 30 ​ ​ ​ 2022 ​ 2021 ​ (millions) ​ ​ COS ​ SG&A ​ Interest ​ ​ COS ​ SG&A ​ Interest ​ Gain (loss) on derivatives in cash flow hedging relationship: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount of gain (loss) reclassified from AOCI to income ​ ​ $0.8 ​ $52.1 ​ $- ​ ​ ​ ($4.6) ​ ($37.4) ​ $- ​ Amount excluded from the assessment of effectiveness recognized in earnings based on changes in fair value ​ ​ - ​ - ​ 7.7 ​ ​ ​ - ​ - ​ 11.3 ​ Interest rate swap agreements ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount of gain (loss) reclassified from AOCI to income ​ ​ - ​ - ​ (1.2) ​ ​ ​ - ​ - ​ (1.2) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gain (loss) on derivatives not designated as hedging instruments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign currency forward contracts ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount of gain (loss) recognized in income (a) ​ ​ - ​ 48.4 ​ - ​ ​ ​ - ​ 5.8 ​ - ​ Total gain (loss) of all derivative instruments ​ ​ $0.8 ​ $100.5 ​ $6.5 ​ ​ ​ ($4.6) ​ ($31.6) ​ $10.1 ​ ​ ​

The change in the Company’s tax rate for the second quarter and first six months of 2022 compared to the second quarter and first six months of 2021 was driven primarily by the impact of discrete tax items and special (gains) and charges. Further information related to special (gains) and charges is included in Note 2. ​ The Company recognized net tax expense related to discrete tax items of $3.7 million and $4.7 million in the second quarter and first six months of 2022, respectively. This included share-based compensation excess tax benefits of $0.7 million and $3.6 million in the second quarter and first six months of 2022, respectively. The amount of this tax benefit is subject to variation in stock price and award exercises. Additionally, the Company recognized discrete tax expense of $4.4 million and $8.3 million during the second quarter and first six months of 2022, respectively, primarily due to audit settlements, reserves for uncertain tax positions, prior year return adjustments, repricing of deferred tax balances, and other changes in estimates. ​ The Company recognized net tax expense related to discrete tax items of $7.7 million and $23.8 million in the second quarter and first six months of 2021, respectively. This included tax expense of $9.5 million related to prior year returns in the second quarter and first six months of 2021, and a deferred tax benefit of $0.9 million and deferred tax expense of $24.2 million associated with transferring certain intangible property between affiliates in the second quarter and first six months of 2021, respectively. Share-based compensation excess tax benefit was $4.2 million and $10.8 million in the second quarter and first six months of 2021. The remaining discrete tax expense of $3.3 million and $0.9 million during the quarter and first six months of 2021, respectively, was primarily due to other changes in estimates. ​

Sales of product to ChampionX post-separation for the second quarter of 2022 and 2021 were $33.9 million and $34.5 million, respectively, and first six months of 2022 and 2021 were $68.6 million and $67.3 million, respectively. As of June 30, 2022, the Company had an outstanding accounts receivable balance for sales of product to ChampionX of $18.1 million. ​ Service and Lease Equipment ​ Service and lease equipment revenue is generated from providing services or leasing equipment to customers. Service offerings include installing or repairing certain types of equipment, activities that supplement or replace headcount at the customer location, or fulfilling deliverables included in the contract. Global Industrial segment services are associated with water treatment and paper process applications. Global Institutional & Specialty segment services include cleaning and sanitizing programs and wash process solutions. Global Healthcare & Life Sciences segment services include pharmaceutical, personal care, infection and containment control solutions. Revenues included in Other primarily relate to services designed to detect, eliminate and prevent pests. Service revenue is recognized over time utilizing an input method and aligns with when the services are provided. Typically, revenue is recognized over time using costs incurred to date because the effort provided by the field selling and service organization represents services provided, which corresponds with the transfer of control. Revenue recognized from leased equipment primarily relates to warewashing and water treatment equipment recognized on a straight-line basis over the length of the lease contract pursuant to Topic 842 Leases. ​ The Company’s operating lease revenue was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Second Quarter Ended ​ Six Months Ended ​ ​ ​ June 30 ​ June 30 ​ (millions) ​ 2022 ​ 2021 ​ 2022 ​ 2021 ​ Operating lease revenue* ​ ​ $115.2 ​ ​ ​ $105.7 ​ ​ ​ $227.3 ​ ​ ​ $203.1 ​ ​ ​ *Includes immaterial variable lease revenue ​ The following table shows principal activities, separated by reportable segments, from which the Company generates its revenue.

The United States made up 53% and 52% of total revenues during the six months ended June 30, 2022 and 2021, respectively. ​ Accounts Receivable and Allowance for Expected Credit Losses ​ Accounts receivable are carried at the invoiced amounts, less an allowance for expected credit losses, and generally do not bear interest. The Company’s allowance for expected credit losses estimates the amount of expected future credit losses by analyzing accounts receivable balances by age and applying historical write-off and collection experience. The Company’s estimates separately consider macroeconomic trends, specific circumstances and credit conditions of customer receivables. Account balances are written off against the allowance when it is determined the receivable will not be recovered. ​ The Company’s allowance for expected return of products shipped and credits related to pricing or quantities shipped was $24.9 million and $19.3 million as of June 30, 2022 and 2021, respectively. Returns and credit activity is recorded directly as a reduction to revenue. ​ The following table summarizes the activity in the allowance for expected credit losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ ​ June 30 ​ (millions) ​ 2022 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ ​ $52.8 ​ ​ ​ $68.4 ​ Bad debt expense ​ 24.8 ​ ​ 7.1 ​ Write-offs ​ (8.5) ​ ​ (8.5) ​ Other (a) ​ 3.8 ​ ​ (6.2) ​ Ending balance ​ ​ $72.9 ​ ​ ​ $60.8 ​ ​ (a) Other amounts are primarily the effects of changes in currency translations. ​ ​ Contract Liability ​ Payments received from customers are based on invoices or billing schedules as established in contracts with customers. Accounts receivable are recorded when the right to consideration becomes unconditional. The contract liability relates to billings in advance of performance (primarily service obligations) under the contract. Contract liabilities are recognized as revenue when the performance obligation has been performed, which primarily occurs during the subsequent quarter. ​ The following table summarizes the contract liability activity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ June 30 (millions) 2022 ​ 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ Contract liability as of beginning of the year ​ $91.7 ​ ​ ​ $80.4 ​ ​ ​ ​ ​ ​ ​ ​ ​ Revenue recognized in the period from: ​ ​ ​ ​ ​ ​ Amounts included in the contract liability at the beginning of the year ​ (91.7) ​ ​ ​ (80.4) ​ ​ ​ ​ ​ ​ ​ ​ ​ Increases due to billings excluding amounts recognized as revenue during the period ended ​ ​ 99.1 ​ ​ ​ 87.9 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contract liability as of end of period ​ ​ $99.1 ​ ​ ​ $87.9 ​ ​

OPERATING SEGMENTS
OPERATING SEGMENTS	​ ​ 15. OPERATING SEGMENTS ​ The Company’s organizational structure consists of global business unit and global regional leadership teams. The Company’s eleven operating segments follow its commercial and product-based activities and are based on engagement in business activities, availability of discrete financial information and review of operating results by the Chief Operating Decision Maker at the identified operating segment level. ​ The Company’s operating segments that share similar economic characteristics and future prospects, nature of the products and production processes, end-use markets, channels of distribution and regulatory environment have been aggregated into three reportable segments: Global Industrial, Global Institutional & Specialty and Global Healthcare & Life Sciences. The Company’s operating segments that do not meet the quantitative criteria to be separately reported have been combined into Other. The Company provides similar information for Other as the Company considers the information regarding its underlying operating segments as useful in understanding its consolidated results. ​ Comparability of Reportable Segments ​ The Company evaluates the performance of its non-U.S. dollar functional currency international operations based on fixed currency exchange rates, which eliminates the impact of exchange rate fluctuations on its international operations. Fixed currency amounts are updated annually at the beginning of each year based on translation into U.S. dollars at foreign currency exchange rates established by management, with all periods presented using such rates. The “Fixed Currency Rate Change” column shown in the following table reflects international operations at fixed currency exchange rates established by management at the beginning of 2022, rather than the 2021 established rates. The difference between the fixed currency exchange rates and the actual currency exchange rates is reported within the “Effect of foreign currency translation” row in the following table. The “Other” column shown in the following table reflects immaterial changes between reportable segments, including the movement of certain customers and cost allocations. ​ The impact of the preceding changes on previously reported full year 2021 reportable segment net sales and operating income is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 Reported ​ ​ ​ ​ ​ ​ ​ Fixed ​ ​ ​ 2021 Reported ​ ​ ​ Valued at 2021 ​ ​ Currency ​ Valued at 2022 ​ (millions) ​ Management Rates Other ​ Rate Change ​ Management Rates ​ Net Sales ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Global Industrial ​ ​ $6,304.9 ​ ​ ​ $- ​ ​ ​ ​ ($218.1) ​ ​ ​ ​ $6,086.8 ​ ​ Global Institutional & Specialty ​ ​ 3,978.2 ​ ​ ​ - ​ ​ ​ ​ (69.4) ​ ​ ​ ​ 3,908.8 ​ ​ Global Healthcare & Life Sciences ​ ​ 1,195.4 ​ ​ ​ - ​ ​ ​ ​ (45.8) ​ ​ ​ ​ 1,149.6 ​ ​ Other ​ ​ 1,226.9 ​ ​ ​ - ​ ​ ​ ​ (25.9) ​ ​ ​ ​ 1,201.0 ​ ​ Corporate ​ ​ 139.4 ​ ​ ​ - ​ ​ ​ ​ (2.0) ​ ​ ​ ​ 137.4 ​ ​ Subtotal at fixed currency rates ​ ​ 12,844.8 ​ ​ ​ - ​ ​ ​ ​ (361.2) ​ ​ ​ ​ 12,483.6 ​ ​ Effect of foreign currency translation ​ ​ (111.7) ​ ​ ​ - ​ ​ ​ ​ 361.2 ​ ​ ​ ​ 249.5 ​ ​ Consolidated reported GAAP net sales ​ ​ $12,733.1 ​ ​ ​ $- ​ ​ ​ ​ $- ​ ​ ​ ​ $12,733.1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating Income ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Global Industrial ​ ​ $1,031.0 ​ ​ ​ $4.0 ​ ​ ​ ​ ($49.3) ​ ​ ​ ​ $985.7 ​ ​ Global Institutional & Specialty ​ ​ 556.9 ​ ​ ​ (3.8) ​ ​ ​ ​ (7.4) ​ ​ ​ ​ 545.7 ​ ​ Global Healthcare & Life Sciences ​ ​ 160.9 ​ ​ ​ (0.9) ​ ​ ​ ​ (7.7) ​ ​ ​ ​ 152.3 ​ ​ Other ​ ​ 187.3 ​ ​ ​ 0.7 ​ ​ ​ ​ (4.0) ​ ​ ​ ​ 184.0 ​ ​ Corporate ​ ​ (318.6) ​ ​ ​ ​ ​ ​ ​ ​ 2.0 ​ ​ ​ ​ (316.6) ​ ​ Subtotal at fixed currency rates ​ ​ 1,617.5 ​ ​ ​ - ​ ​ ​ ​ (66.4) ​ ​ ​ ​ 1,551.1 ​ ​ Effect of foreign currency translation ​ ​ (18.9) ​ ​ ​ ​ ​ ​ ​ ​ 66.4 ​ ​ ​ ​ 47.5 ​ ​ Consolidated reported GAAP operating income ​ ​ $1,598.6 ​ ​ ​ $- ​ ​ ​ ​ $- ​ ​ ​ ​ $1,598.6 ​ ​ ​ Reportable Segment Information ​ Financial information for the Company’s reportable segments, is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Second Quarter Ended ​ Six Months Ended ​ ​ ​ June 30 ​ June 30 ​ (millions) 2022 ​ ​ 2021 ​ 2022 ​ ​ 2021 ​ Net Sales ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Global Industrial ​ $1,704.1 ​ ​ ​ $1,502.3 ​ ​ $3,261.1 ​ ​ ​ $2,887.2 ​ Global Institutional & Specialty ​ ​ 1,135.1 ​ ​ ​ 963.5 ​ ​ 2,140.2 ​ ​ ​ 1,807.6 ​ Global Healthcare & Life Sciences ​ ​ 400.8 ​ ​ ​ 292.0 ​ ​ 763.4 ​ ​ ​ 573.1 ​ Other ​ ​ 342.3 ​ ​ ​ 300.3 ​ ​ 638.3 ​ ​ ​ 565.7 ​ Corporate ​ ​ 33.9 ​ ​ ​ 34.5 ​ ​ 68.6 ​ ​ ​ 67.3 ​ Subtotal at fixed currency rates ​ ​ 3,616.2 ​ ​ ​ 3,092.6 ​ ​ 6,871.6 ​ ​ ​ 5,900.9 ​ Effect of foreign currency translation ​ ​ (35.6) ​ ​ ​ 70.1 ​ ​ (24.3) ​ ​ ​ 146.8 ​ Consolidated reported GAAP net sales ​ $3,580.6 ​ ​ $3,162.7 ​ ​ $6,847.3 ​ ​ ​ $6,047.7 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating Income ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Global Industrial ​ $227.0 ​ ​ ​ $251.3 ​ ​ $416.2 ​ ​ ​ $461.1 ​ Global Institutional & Specialty ​ ​ 152.6 ​ ​ ​ 137.7 ​ ​ 263.4 ​ ​ ​ 199.6 ​ Global Healthcare & Life Sciences ​ ​ 58.5 ​ ​ ​ 46.1 ​ ​ 102.6 ​ ​ ​ 88.7 ​ Other ​ ​ 52.0 ​ ​ ​ 50.8 ​ ​ 89.2 ​ ​ ​ 83.1 ​ Corporate ​ ​ (57.9) ​ ​ ​ (50.9) ​ ​ (187.5) ​ ​ ​ (113.4) ​ Subtotal at fixed currency rates ​ ​ 432.2 ​ ​ ​ 435.0 ​ ​ 683.9 ​ ​ ​ 719.1 ​ Effect of foreign currency translation ​ ​ (6.4) ​ ​ ​ 12.8 ​ ​ (3.6) ​ ​ ​ 26.0 ​ Consolidated reported GAAP operating income ​ $425.8 ​ ​ $447.8 ​ ​ $680.3 ​ ​ ​ $745.1 ​ ​ The profitability of the Company’s operating segments is evaluated by management based on operating income. ​ Consistent with the Company’s internal management reporting, Corporate amounts in the table above include sales to ChampionX in accordance with the long-term supply agreement entered into with the Transaction, as discussed in Note 14.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES	6 Months Ended

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	16. COMMITMENTS AND CONTINGENCIES ​ The Company is subject to various claims and contingencies related to, among other things, workers’ compensation, general liability (including product liability), automobile claims, health care claims, environmental matters and lawsuits. The Company is also subject to various claims and contingencies related to income taxes. The Company also has contractual obligations including lease commitments. ​ The Company records liabilities when a contingent loss is probable and can be reasonably estimated. If the reasonable estimate of a probable loss is a range, the Company records the most probable estimate of the loss or the minimum amount when no amount within the range is a better estimate than any other amount. The Company discloses a contingent liability even if the liability is not probable or the amount is not estimable, or both, if there is a reasonable possibility that a material loss may have been incurred. ​ Insurance ​ Globally, the Company has insurance policies with varying deductible levels for property and casualty losses. The Company is insured for losses in excess of these deductibles, subject to policy terms and conditions and has recorded both a liability and an offsetting receivable for amounts in excess of these deductibles. The Company is self-insured for health care claims for eligible participating employees, subject to certain deductibles and limitations. The Company determines its liabilities for claims on an actuarial basis. ​ Litigation and Environmental Matters ​ The Company and certain subsidiaries are party to various lawsuits, claims and environmental actions that have arisen in the ordinary course of business. These include from time to time antitrust, employment, commercial, patent infringement, tort, product liability and wage hour lawsuits, as well as possible obligations to investigate and mitigate the effects on the environment of the disposal or release of certain chemical substances at various sites, such as Superfund sites and other operating or closed facilities. The Company has established accruals for certain lawsuits, claims and environmental matters. The Company currently believes that there is not a reasonably possible risk of material loss in excess of the amounts accrued related to these legal matters. Because litigation is inherently uncertain, and unfavorable rulings or developments could occur, there can be no certainty that the Company may not ultimately incur charges in excess of recorded liabilities. A future adverse ruling, settlement or unfavorable development could result in future charges that could have a material adverse effect on the Company’s results of operations or cash flows in the period in which they are recorded. The Company currently believes that such future charges related to suits and legal claims, if any, would not have a material adverse effect on the Company’s consolidated financial position. ​ TPC Group Litigation ​ On November 27, 2019, a Butadiene production plant owned and operated by TPC Group, Inc. in Port Neches, Texas, experienced an explosion and fire that resulted in personal injuries, the release of chemical fumes and extensive property damage to the plant and surrounding areas in and near Port Neches, Texas. ​ Nalco Company LLC, a subsidiary of Ecolab, supplied process chemicals to TPC used in TPC’s production processes. Nalco did not operate, manage, maintain or control any aspect of TPC’s plant operations. ​ In connection with its provision of process chemicals to TPC, Nalco has been named in numerous lawsuits stemming from the plant explosion. Nalco has been named a defendant, along with TPC and other defendants, in multi-district litigation (“MDL”) proceedings pending in Orange County, Texas, alleging among other things claims for personal injury, property damage and business losses (In re TPC Group Litigation – A2020-0236-MDL, Orange County, Texas). In addition, numerous other lawsuits have been filed against Nalco, including TPC Group v. Nalco, E0208239, Jefferson County, Texas, a subrogation claim by TPC’s insurers seeking reimbursement for property damage losses. Over 5,000 plaintiffs (including the subrogation matter) currently have claims against Nalco. ​ All of these cases make similar allegations and seek damages for personal injury, property damage, business losses and other damages, including exemplary damages. The Company expects all these cases will be consolidated for pretrial purposes into the Orange County MDL referenced above. Due to the large number of plaintiffs, the early stage of the litigation and the fact that many of the claims do not specify an amount of damages, any estimate of any loss or range of losses cannot be made at this time. ​ The Company believes these claims asserted against Nalco Company LLC are without merit and intend to defend the claims vigorously. The Company also believes the claims should be covered by insurance subject to deductibles. However, the Company cannot predict the outcome of these lawsuits, the involvement the Company might have in these matters in the future or the potential for future litigation. ​ On June 1, 2022, TPC and seven of its affiliated companies filed for bankruptcy reorganization under Chapter 11 (Case No. 22-10493-CTG, United States Bankruptcy Court for the District of Delaware), and actions in the bankruptcy case are expected to continue through October 2022. ​ Environmental Matters ​ The Company is currently participating in environmental assessments and remediation at approximately 30 locations, the majority of which are in the U.S., and environmental liabilities have been accrued reflecting management’s best estimate of future costs. Potential insurance reimbursements are not anticipated in the Company’s accruals for environmental liabilities. ​
