Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 1) Consolidation, Noncontrolling Interests and Basis of Presentation Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, our Consolidated Financial Statements include 100 % of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three-month periods ending August 31, November 30 and May 31, respectively, with weaker performance in our third fiscal quarter (December through February). 2) Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. 3) Acquisitions/Divestitures We account for business combinations and asset acquisitions using the acquisition method of accounting and, accordingly, the assets and liabilities of the acquired entities are recorded at their estimated fair values at the acquisition date. During the fiscal year ended May 31, 2022, we completed a total of eight acquisitions in three of our four reportable segments. Most notably, within our CPG reportable segment, we acquired a chemical manufacturing facility located in Corsicana, Texas. The facility will be repurposed to act as a manufacturing campus for a number of RPM's operating companies. Also within our CPG reportable segment, we acquired a provider of indoor air quality solutions headquartered in Clearwater, Florida. We also completed several other acquisitions within our CPG, SPG and PCG reportable segments. During the fiscal year ended May 31, 2021, we completed a total of four acquisitions in each of our four reportable segments. Within our Consumer reportable segment, we acquired a manufacturer of sandpaper and other abrasives headquartered in Fairborn, Ohio. Within our PCG reportable segment, we acquired a manufacturer of raised flooring systems headquartered in Denver, Colorado. We also completed other acquisitions within our SPG and CPG reportable segments. The purchase price for each acquisition has been allocated to the estimated fair values of the assets acquired and liabilities assumed as of the date of acquisition. We have finalized the purchase price allocation for our fiscal 2021 acquisitions. For acquisitions completed during fiscal 2022, the valuations of consideration transferred, total assets acquired and liabilities assumed are substantially complete. The primary areas that remain open relate to working capital adjustments and other intangible asset valuations. Acquisitions are aggregated by year of purchase in the following table : Fiscal 2022 Acquisitions Fiscal 2021 Acquisitions (In thousands) Weighted-Average Total Weighted-Average Total Current assets $ 9,604 $ 50,310 Property, plant and equipment 71,658 27,012 Goodwill N/A 30,747 N/A 41,654 Trade names - indefinite lives N/A 1,050 N/A 16,694 Other intangible assets 13 21,010 20 53,894 Other long-term assets 2,316 6,831 Total Assets Acquired $ 136,385 $ 196,395 Liabilities assumed ( 7,159 ) ( 24,232 ) Net Assets Acquired $ 129,226 (1) $ 172,163 (2) (1) Figure includes cash acquired of $ 1.8 million. (2) Figure includes cash acquired of $ 6.4 million. Our Consolidated Financial Statements reflect the results of operations of acquired businesses as of their respective dates of acquisition. Pro-forma results of operations for the years ended May 31, 2022 and 2021 were not materially different from reported results and, consequently, are not presented. 4) Foreign Currency The functional currency for each of our foreign subsidiaries is its principal operating currency. Accordingly, for the periods presented, assets and liabilities have been translated using exchange rates at year end, while income and expense for the periods have been translated using a weighted-average exchange rate. The resulting translation adjustments have been recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity, and will be included in net earnings only upon the sale or liquidation of the underlying foreign investment, neither of which is contemplated at this time. Transaction losses increased during the current fiscal year due to the strengthening of the U.S. dollar, resulting in net transactional losses of approximately $ 4.3 million. This compared to more moderate net transactional foreign exchange losses in fiscal 2021 of approximately $ 2.8 million, and net transactional foreign exchange gains for fiscal 2020 of approximately $ 0.3 million as a result of more modest fluctuations in the strength of the U.S. dollar. 5) Cash and Cash Equivalents We consider all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. We do not believe we are exposed to any significant credit risk on cash and cash equivalents. The carrying amounts of cash and cash equivalents approximate fair value. 6) Property, Plant & Equipment May 31, 2022 2021 (In thousands) Land $ 88,137 $ 93,455 Buildings and leasehold improvements 519,391 518,205 Machinery and equipment 1,525,387 1,355,822 Total property, plant and equipment, at cost 2,132,915 1,967,482 Less: allowance for depreciation and amortization 1,028,932 1,002,300 Property, plant and equipment, net $ 1,103,983 $ 965,182 We review long-lived assets for impairment when circumstances indicate that the carrying values of these assets may not be recoverable. For assets that are to be held and used, an impairment charge is recognized when the estimated undiscounted future cash flows associated with the asset or group of assets are less than their carrying value. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is recorded for the difference between the carrying value and the fair value. Fair values are determined based on quoted market values, discounted cash flows, internal appraisals or external appraisals, as applicable. Assets to be disposed of are carried at the lower of their carrying value or estimated net realizable value. Depreciation is computed primarily using the straight-line method over the following ranges of useful lives: Buildings and leasehold improvements 1 to 50 years Machinery and equipment 1 to 36 years Total deprecia tion expense for each fiscal period includes the charges to income that result from the amortization of assets recorded under finance leases. For the periods ended May 31, 2022, 2021 and 2020, we recorded depreciation expense of $ 104.3 million, $ 99.4 million, and $ 108.5 million , respectively. 7) Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. The majority of our revenue is recognized at a point in time. However, we also record revenues generated under construction contracts, mainly in connection with the installation of specialized roofing and flooring systems and related services. For certain polymer flooring installation projects, we account for our revenue using the output method, as we consider square footage of completed flooring to be the best measure of progress toward the complete satisfaction of the performance obligation. In contrast, for certain of our roofing installation projects, we account for our revenue using the input method, as that method was the best measure of performance as it considers costs incurred in relation to total expected project costs, which essentially represents the transfer of control for roofing systems to the customer. In general, for our construction contracts, we record contract revenues and related costs as our contracts progress on an over-time model. 8) Shipping Costs We identify shipping and handling costs as costs paid to third-party shippers for transporting products to customers, and we include these costs in cost of sales in our Consolidated Statements of Income. 9) Allowance for Credit Losses Our primary allowance for credit losses is the allowance for doubtful accounts. The allowance for doubtful accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The allowance is established using assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowances for doubtful collection of accounts are included in selling, general and administrative expenses. Actual collections of trade receivables could differ from our estimates due to changes in future economic or industry conditions or specific customer’s financial conditions. For the periods ended May 31, 2022, 2021 and 2020, bad debt expense approximated $ 4.3 million, $ 10.0 million and $ 16.7 million, respectively. Bad debt expense was elevated in fiscal 2021 and 2020 due in part to additional write-offs associated with exiting unprofitable product lines and regions in conjunction with our MAP to Growth. Fiscal 2020 bad debt expense also re flects, although to a much lesser degree, the impact the Covid pandemic had on some of our customers’ ability to pay timely. 10) Inventories Inventories are stated at the lower of cost or net realizable value, cost being determined on a first-in, first-out (FIFO) basis and net realizable value being determined on the basis of replacement cost. Inventory costs include raw materials, labor and manufacturing overhead. We review the net realizable value of our inventory in detail on an on-going basis, with consideration given to various factors, which include our estimated reserves for excess, obsolete, slow-moving or distressed inventories. If actual market conditions differ from our projections, and our estimates prove to be inaccurate, write-downs of inventory values and adjustments to cost of sales may be required. Historically, our inventory reserves have approximated actual experience. For the periods ended May 31, 2022, 2021 and 2020, charges related to slow moving and/or obsolete inventory on hand approximated $ 9.8 million, $ 3.7 million and $ 39.6 million, respectively. Charges recorded during fiscal 2022 and fiscal 2021 were more normalized in comparison to fiscal 2020, which had elevated inventory charges associated with our MAP to Growth restructuring activities. During fiscal 2020, we recorded $ 28.8 million within our Consumer reportable segment consisting of proactive management of excess quantities of inventory in order to accelerate cash conversion, SKU rationalization, and exiting unprofitable product lines and regions and $ 3.2 million within our PCG segmen t related to exiting unprofitable product lines and regions. Inventories were composed of the following major classes: May 31, 2022 2021 (In thousands) Raw materials and supplies $ 560,886 $ 447,220 Finished goods 651,732 490,875 Total Inventory $ 1,212,618 $ 938,095 11) Goodwill and Other Intangible Assets We account for goodwill and other intangible assets in accordance with the provisions of Accounting Standards Codification ("ASC") 350 and account for business combinations using the acquisition method of accounting and, accordingly, the assets and liabilities of the entities acquired are recorded at their estimated fair values at the acquisition date. Goodwill Goodwill represents the excess of the purchase price paid over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination as of the acquisition date. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill. We evaluate our reporting units when changes in our operating structure occur, and if necessary, reassign goodwill using a relative fair value allocation approach. We test our goodwill balances at least annually, or more frequently as impairment indicators arise, at the reporting unit level. Our annual impairment assessment date has been designated as the first day of our fourth fiscal quarter. Our reporting units have been identified at the component level, which is one level below our operating segments. We follow the Financial Accounting Standards Board (“FASB”) guidance found in ASC 350 that simplifies how an entity tests goodwill for impairment. It provides an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, and whether it is necessary to perform a quantitative goodwill impairment test. We assess qualitative factors in each of our reporting units that carry goodwill. We assess these qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. The quantitative process is required only if we conclude that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. However, we have an unconditional option to bypass a qualitative assessment and proceed directly to performing the quantitative analysis. We applied the quantitative process during our annual goodwill impairment assessments performed during the fourth quarters of fiscal 2022, 2021 and 2020. In applying the quantitative test, we compare the fair value of a reporting unit to its carrying value. If the calculated fair value is less than the current carrying value, then impairment of the reporting unit exists. Calculating the fair value of a reporting unit requires our use of estimates and assumptions. We use significant judgment in determining the most appropriate method to establish the fair value of a reporting unit. We estimate the fair value of a reporting unit by employing various valuation techniques, depending on the availability and reliability of comparable market value indicators, and employ methods and assumptions that include the application of third-party market value indicators and the computation of discounted future cash flows determined from estimated cashflow adjustments to a reporting unit’s annual projected earnings before interest, taxes, depreciation and amortization (“EBITDA”), or adjusted EBITDA, which adjusts for one-off items impacting revenues and/or expenses that are not considered by management to be indicative of ongoing operations. Our fair value estimations may include a combination of value indications from both the market and income approaches, as the income approach considers the future cash flows from a reporting unit’s ongoing operations as a going concern, while the market approach considers the current financial environment in establishing fair value. In applying the market approach, we use market multiples derived from a set of similar companies. In applying the income approach, we evaluate discounted future cash flows determined from estimated cashflow adjustments to a reporting unit’s projected EBITDA. Under this approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows. In applying the discounted cash flow methodology utilized in the income approach, we rely on a number of factors, including future business plans, actual and forecasted operating results, and market data. The significant assumptions employed under this method include discount rates; revenue growth rates, including assumed terminal growth rates; and operating margins used to project future cash flows for a reporting unit. The discount rates utilized reflect market-based estimates of capital costs and discount rates adjusted for management’s assessment of a market participant’s view with respect to other risks associated with the projected cash flows of the individual reporting unit. Our estimates are based upon assumptions we believe to be reasonable, but which by nature are uncertain and unpredictable. We believe we incorporate ample sensitivity ranges into our analysis of goodwill impairment testing for a reporting unit, such that actual experience would need to be materially out of the range of expected assumptions in order for an impairment to remain undetected. Changes in the Composition of Reporting Units in Fiscal 2020 On June 1, 2019, the composition of our reportable segments was revised. Prior to implementing the revised segment reporting structure beginning in fiscal 2020, our previously disclosed Industrial segment comprised two operating segments, the CPG operating segment and the PCG operating segment. Each of these operating segments comprised several reporting units, all of which were tested during the annual goodwill impairment tests during the fourth quarter of fiscal 2020, 2021 and 2022. Also, in connection with our Map to Growth, we realigned certain businesses and management structure within our SPG segment. As such, our former Wood Finishes Group reporting unit was split into two separate reporting units: Guardian and Wood Finishes Group. Additionally, our former Kop-Coat Group reporting unit was split into two reporting units: Kop-Coat Industrial Protection Products and Kop-Coat Group. We performed an interim goodwill impairment test for each of the new reporting units upon the change in business realignment using a quantitative assessment. We concluded that the estimated fair values exceeded the carrying values for these new reporting units, and accordingly, no indications of impairment were identified as a result of these changes during the first quarter of fiscal 2020. Conclusion on Annual Goodwill Impairment Tests As a result of the annual impairment assessments performed for fiscal 2022, 2021 and 2020, there were no goodwill impairments. Indefinite-Lived Intangible Assets Additionally, we test all indefinite-lived intangible assets for impairment at least annually during our fiscal fourth quarter. We follow the guidance provided by ASC 350 that simplifies how an entity tests indefinite-lived intangible assets for impairment. It provides an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount before applying traditional quantitative tests. We applied quantitative processes during our annual indefinite-lived intangible asset impairment assessments performed during the fourth quarters of fiscal 2022, 2021 and 2020. The annual impairment assessment involves estimating the fair value of each indefinite-lived asset and comparing it with its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, we record an impairment loss equal to the difference. Calculating the fair value of the indefinite-lived assets requires our significant use of estimates and assumptions. We estimate the fair values of our intangible assets by applying a relief-from-royalty calculation, which includes discounted future cash flows related to each of our intangible asset’s projected revenues. In applying this methodology, we rely on a number of factors, including actual and forecasted revenues and market data. Our required annual impairment test of each of our indefinite-lived intangible assets performed during fiscal 2022, 2021 and 2020 did not result in an impairment charge. Although no impairment losses were recorded as a result of our annual impairment tests, we did record an intangible impairment charge in fiscal 2020. In fiscal 2020, in connection with Map to Growth, we recorded an impairment charge of $ 4.0 million included in restructuring expense in our Consumer reportable segment for impairment losses on indefinite-lived trade names. Refer to Note C “Goodwill and Other Intangible Assets” for additional details on this indefinite-lived intangible asset impairment charge. Definite-Lived Intangible Assets In accordance with the guidance provided by ASC 360, we assess identifiable, amortizable intangibles assets for impairment whenever events or changes in facts and circumstances indicate the possibility that the carrying values of these assets may not be recoverable over their estimated remaining useful lives. Factors considered important in our assessment, which might trigger an impairment evaluation, include the following: • significant under-performance relative to historical or projected future operating results; • significant changes in the manner of our use of the acquired assets; • significant changes in the strategy for our overall business; and • significant negative industry or economic trends. Measuring a potential impairment of amortizable intangibles assets requires the use of various estimates and assumptions, including the determination of which cash flows are directly related to the assets being evaluated, the respective useful lives over which those cash flows will occur and potential residual values, if any. If we determine that the carrying values of these assets may not be recoverable based upon the existence of one or more of the above-described indicators or other factors, any impairment amounts would be measured based on the projected net cash flows expected from these assets, including any net cash flows related to eventual disposition activities. The determination of any impairment losses would be based on the best information available, including internal estimates of discounted cash flows; market participant assumptions; quoted market prices, when available; and independent appraisals, as appropriate, to determine fair values. Cash flow estimates would be based on our historical experience and our internal business plans, with appropriate discount rates applied. We did not record any impairment charges related to our definite-lived intangible assets during fiscal 2022, 2021 and 2020. 12) Advertising Costs Advertising costs are charged to operations w hen incurred and are included in SG&A expenses. For the years ended May 31, 2022, 2021 and 2020, advertising costs were $ 45.4 million, $ 61.1 million and $ 49.7 million, respectively. 13) Research and Development Research and development costs are charged to operations when incurred and are included in SG&A expenses. The amounts charged to expense for the years ended May 31, 2022, 2021 and 2020 were $ 80.5 million, $ 77.6 million and $ 76.5 million, respectively. 14) Stock-Based Compensation Stock-based compensation represents the cost related to stock-based awards granted to our associates and directors, which may include restricted stock and stock appreciation rights (“SARs”). We measure stock-based compensation cost at the date of grant, based on the estimated fair value of the award. We recognize the cost as expense on a straight-line basis (net of estimated forfeitures) over the related vesting period. Refer to Note J, “Stock-Based Compensation,” for further information. 15) Investment Expense (Income), Net Investment expense (income), net, consists of the following components: Year Ended May 31, 2022 2021 2020 (In thousands) Interest (income) $ ( 4,435 ) $ ( 3,555 ) $ ( 5,313 ) Net loss (gain) on marketable securities 17,706 ( 38,774 ) ( 1,629 ) Dividend (income) ( 5,676 ) ( 2,121 ) ( 2,797 ) Investment expense (income), net $ 7,595 $ ( 44,450 ) $ ( 9,739 ) Net Loss (Gain) on Marketable Securities Year Ended May 31, 2022 2021 2020 (In thousands) Unrealized losses (gains) on marketable equity securities $ 19,164 $ ( 16,133 ) $ ( 1,457 ) Realized (gains) on marketable equity securities ( 1,488 ) ( 22,680 ) ( 237 ) Realized losses on available-for-sale debt securities 30 39 65 Net loss (gain) on marketable securities $ 17,706 $ ( 38,774 ) $ ( 1,629 ) 16) Other (Income) Expense, Net Other (income) expense, net, consists of the following components: Year Ended May 31, 2022 2021 2020 (In thousands) Royalty (income) expense, net (a) $ ( 915 ) $ ( 387 ) $ 5,206 (Income) related to unconsolidated equity affiliates ( 350 ) ( 516 ) ( 165 ) Pension non-service (credit) cost ( 10,581 ) 14,542 6,076 Loss on divestiture (b) - - 949 Other (income) expense, net $ ( 11,846 ) $ 13,639 $ 12,066 (a) Includes a $ 5.3 million charge incurred during the fourth quarter of fiscal 2020 related to the termination of a licensing agreement within our Consumer reportable segment. (b) Reflects the loss incurred upon divestiture of a contracting business located in Australia, which had reported through our PCG segment. 17) Income Taxes The provision for income taxes is calculated using the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for the tax effect of temporary differences between the financial statement carrying amount of assets and liabilities and the amounts used for income tax purposes and for certain changes in valuation allowances. Valuation allowances are recorded to reduce certain deferred tax assets when, in our estimation, it is more likely than not that a tax benefit will not be realized. 18) Earnings Per Share of Common Stock Earnings per share (EPS) is computed using both the treasury stock and two-class method, as our unvested share-based payment awards contain rights to receive non-forfeitable dividends are considered participating securities. We calculate both Basic and Diluted EPS under each method and compare the results, reporting the method that is most dilutive. Basic EPS of common stock is computed by dividing net income by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS of common stock is computed on the basis of the weighted-average number of shares of common stock, plus the effect of dilutive potential shares of common stock outstanding during the period using the treasury stock method. Dilutive potential shares of common stock include outstanding SARS and restricted stock awards. The treasury stock method also assumes that we use the proceeds from the hypothetical exercise of the stock compensation awards to repurchase common stock at the average market price during the period. The two-class method determines EPS for each class of common stock and participating securities according to dividends and dividend equivalents and their respective participation rights in undistributed earnings. See Note L, “Earnings Per Share,” to the Consolidated Financial Statements for additional information. 19) Recent Accounting Pronouncements New Pronouncements Adopted In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740),” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments was permitted. Depending on the amendment, adoption may have been applied on the retrospective, modified retrospective or prospective basis. The adoption of this new guidance, effective June 1, 2021 using the prospective method, did no t have a material impact on our Consolidated Financial Statements. New Pronouncements Issued We are not aware of any recently issued accounting pronouncements that have not yet been adopted by us and which would have a material impact on our consolidated financial statements. 20) Subsequent Event From June 1, 2022 through July 22, 2022, we repurchased 303,079 shares of RPM common stock since May 31, 2022, at a cost of approximately $ 25.0 million, or an average of $ 82.49 per share, under the stock repurchase program described further in Note I, "Stock Repurchase Program."

Restructuring

Restructuring	12 Months Ended

Restructuring and Related Activities [Abstract]
Restructuring	NOTE B — RESTRUCTURING We record restructuring charges associated with management-approved restructuring plans to either reorganize one or more of our business segments, or to remove duplicative headcount and infrastructure associated with our businesses. Restructuring charges can include severance costs to eliminate a specified number of associates, infrastructure charges to vacate facilities and consolidate operations, contract cancellation costs and other costs. Restructuring charges are recorded based upon planned associate termination dates and site closure and consolidation plans. The timing of associated cash payments is dependent upon the type of restructuring charge and can extend over a multi-year period. We record the short-term portion of our restructuring liability in Other Accrued Liabilities and the long-term portion, if any, in Other Long-Term Liabilities in our Consolidated Balance Sheets. MAP to Growth Between May and August 2018, we approved and implemented the initial phases of a multi-year restructuring plan, which was originally referred to as the 2020 Margin Acceleration Plan (“2020 MAP to Growth”). The initial phases of our 2020 MAP to Growth affected all of our reportable segments, as well as our corporate/nonoperating segment, and focused on margin improvement by simplifying business processes; reducing inventory categories and rationalizing SKUs; eliminating underperforming businesses; reducing headcount and working capital; and improving operating efficiency. The disruption caused by the outbreak of the Covid pandemic delayed the finalization of our 2020 MAP to Growth past the original target completion date of December 31, 2020. In recognition of the fact our restructuring plan extends past calendar year 2020, we began referring to it simply as our “MAP to Growth.” On May 31, 2021, we formally concluded our MAP to Growth. However, certain projects identified prior to May 31, 2021 will not be completed until fiscal 2023, and as such, we have incurred costs in fiscal 2022 and we plan to continue recognizing restructuring expense throughout fiscal 2023. The final implementation and total expected costs are subject to change as we complete these projects. Our execution of the MAP to Growth drove the de-layering and simplification of management and businesses associated with group realignment. We have implemented four center-led functional areas including manufacturing and operations; procurement and supply chain; information technology; and accounting and finance. Our MAP to Growth optimized our manufacturing facilities and provided more efficient plant and distribution facilities. Through the balance sheet date, in association with our MAP to Growth, we have completed, or are in the process of completing, the planned closure of 31 plants and 28 warehouses. We also expect to incur additional severance and benefit costs as part of our planned closure of these facilities. The current total expected costs associated with this plan are outlined in the table below and increased by approximately $ 0.9 million compared to our prior quarter estimate, primarily attributable to increases of approximately $ 0.6 million in expected severance and benefit costs and $ 0.3 million in facility and other closure costs. A summary of the charges recorded in connection with restructuring by reportable segment during is as follows: Year Ended Year Ended Year Ended Cumulative Total (In thousands) May 31, 2022 May 31, 2021 May 31, 2020 to Date Costs CPG Segment: Severance and benefit costs (credits) (a) $ ( 163 ) $ 3,194 $ 6,866 $ 21,125 $ 21,125 Facility closure and other related costs 1,810 2,103 1,508 8,390 8,606 Other asset write-offs 4 38 352 1,982 1,982 Total Charges $ 1,651 $ 5,335 $ 8,726 $ 31,497 $ 31,713 PCG Segment: Severance and benefit costs (b) $ 324 $ 2,974 $ 6,973 $ 16,683 $ 17,252 Facility closure and other related costs 823 1,282 1,873 7,452 7,997 Other asset write-offs - 316 248 917 917 Total Charges $ 1,147 $ 4,572 $ 9,094 $ 25,052 $ 26,166 Consumer Segment: Severance and benefit costs (c) $ - $ 1,840 $ 3,089 $ 12,307 $ 12,307 Facility closure and other related costs 1,038 3,147 2,245 13,119 13,119 Other asset write-offs - 301 4,094 4,420 4,420 Total Charges $ 1,038 $ 5,288 $ 9,428 $ 29,846 $ 29,846 SPG Segment: Severance and benefit costs (d) $ 249 $ 1,197 $ 1,592 $ 8,376 $ 9,289 Facility closure and other related costs 679 1,424 2,922 6,269 6,487 Other asset write-offs ( 1 ) 99 119 1,220 1,220 Total Charges $ 927 $ 2,720 $ 4,633 $ 15,865 $ 16,996 Corporate/Other Segment: Severance and benefit costs (e) $ 1,513 $ 191 $ 1,227 $ 15,051 $ 15,051 Total Charges $ 1,513 $ 191 $ 1,227 $ 15,051 $ 15,051 Consolidated: Severance and benefit costs $ 1,923 $ 9,396 $ 19,747 $ 73,542 $ 75,024 Facility closure and other related costs 4,350 7,956 8,548 35,230 36,209 Other asset write-offs 3 754 4,813 8,539 8,539 Total Charges $ 6,276 $ 18,106 $ 33,108 $ 117,311 $ 119,772 a) Severance and benefit recoveries are associated with the adjustment of previously estimated severance accruals partially offset by the elimination of 16 p ositions during fiscal 2022. Severance and benefit costs are associated with the elimination of 34 positions and 112 positions during fiscal 2021 and 2020, respectively. b) Severance and benefit costs are associated with the elimination of 7 positions, 71 positions and 161 positions during fiscal 2022, 2021 and 2020, respectively. c) Severance and benefit costs are associated with the elimination of 29 positions and 92 positions during fiscal 2021 and 2020, respectively. d) Severance and benefit costs are associated with the elimination of 18 positions and 35 positions and 94 positions during fiscal 2022, 2021 and 2020, respectively. e) Severance and benefit costs are associated with the elimination of one position and two positions during fiscal 2022 and 2020, respectively. A summary of the activity in the restructuring reserves related to our MAP to Growth is as follows: (In thousands) Severance and Facility Other Asset Total Balance at June 1, 2020 $ 7,357 $ 5,880 $ - $ 13,237 Additions charged to expense 9,396 7,956 754 18,106 Cash payments charged against reserve ( 12,413 ) ( 8,268 ) ( 335 ) ( 21,016 ) Non-cash charges and other adjustments 90 ( 4,278 ) ( 419 ) ( 4,607 ) Balance at May 31, 2021 $ 4,430 $ 1,290 $ - $ 5,720 Additions charged to expense 1,923 4,350 3 6,276 Cash payments charged against reserve ( 4,779 ) ( 4,013 ) - ( 8,792 ) Non-cash charges and other adjustments ( 784 ) ( 625 ) ( 3 ) ( 1,412 ) Balance at May 31, 2022 $ 790 $ 1,002 $ - $ 1,792 We did no t incur any material inventory-related charges in connection with our MAP to Growth, during fiscal 2022. In connection with our MAP to Growth, during fiscal 2021, we incurred approximately $ 1.5 million and $ 0.1 million of inventory-related charges at our Consumer and CPG segments, respectively. All of the aforementioned inventory-related charges were the result of initiatives in connection with our overall plan of restructuring, and are recorded in costs of sales in our Consolidated Statements of Income. In connection with our MAP to Growth, during fiscal 2020, we incurred approximately $ 16.3 million, $ 3.2 million, $ 0.7 million and $ 0.1 million of inventory-related charges at our Consumer, PCG, CPG and SPG segments, respectively. All of the aforementioned inventory-related charges were the result of the exit of a business or product line and SKU rationalization initiatives in connection with our overall plan of restructuring, and are recorded in cost of sales in our Consolidated Statements of Income.

Goodwill and Other Intangible Assets	NOTE C — GOODWILL AND OTHER INTANGIBLE ASSETS The changes in the carrying amount of goodwill, by reportable segment, for the years ended May 31, 2022 and 2021, are as follows: CPG PCG Consumer SPG (In thousands) Segment Segment Segment Segment Total Balance as of June 1, 2020 $ 405,354 $ 185,404 $ 496,218 $ 163,090 $ 1,250,066 Acquisitions 2,295 16,174 20,126 2,134 40,729 Translation adjustments & other 35,866 5,460 8,886 4,747 54,959 Balance as of May 31, 2021 443,515 207,038 525,230 169,971 1,345,754 Acquisitions 24,539 5,342 - 866 30,747 Translation adjustments & other ( 14,403 ) ( 10,565 ) ( 9,633 ) ( 4,032 ) ( 38,633 ) Balance as of May 31, 2022 $ 453,651 $ 201,815 $ 515,597 $ 166,805 $ 1,337,868 Total accumulated goodwill impairment losses were $ 156.3 million at May 31, 2022. Of the accumulated balance, $ 141.4 million was recorded during the fiscal year ended May 31, 2017 by a reporting unit that at the time was included in our Consumer segment and is now included in our SPG segment, and $ 14.9 million was recorded during the fiscal year ended May 31, 2009 by a reporting unit that at the time was included in our former Industrial reportable segment and is now included in our CPG segment. There were no impairment losses recorded during fiscal 2022, 2021 or 2020.

Marketable Securities	NOTE D — MARKETABLE SECURITIES The following tables summarize available-for-sale debt securities held at May 31, 2022 and 2021 by asset type: Available-For-Sale Debt Securities (In thousands) Amortized Gross Gross Fair Value May 31, 2022 Fixed maturity: U.S. treasury and other government $ 26,522 $ 55 $ ( 1,338 ) $ 25,239 Corporate bonds 147 12 ( 4 ) 155 Total available-for-sale debt securities $ 26,669 $ 67 $ ( 1,342 ) $ 25,394 Available-For-Sale Debt Securities (In thousands) Amortized Gross Gross Fair Value May 31, 2021 Fixed maturity: U.S. treasury and other government $ 26,154 $ 593 $ ( 184 ) $ 26,563 Corporate bonds 143 39 - 182 Total available-for-sale debt securities $ 26,297 $ 632 $ ( 184 ) $ 26,745 Marketable securities are composed of available-for-sale debt securities and marketable equity securities and all marketable securities are reported at fair value. We carry a portion of our marketable securities portfolio in long-term assets since they are generally held for the settlement of our general and product liability insurance claims processed through our wholly owned captive insurance subsidiaries. Available-for-sale debt securities are included in other current and long-term assets totaling $ 6.0 million and $ 19.4 million at May 31, 2022, respectively, and included in other current and long-term assets totaling $ 3.9 million and $ 22.8 million at May 31, 2021, respectively. Realized gains and losses on sales of available-for-sale debt securities are recognized in net income on the specific identification basis. Changes in the fair values of available-for-sale debt securities that are determined to be holding gains or losses are recorded through accumulated other comprehensive income (loss), net of applicable taxes, within stockholders' equity. In assessing whether a credit loss exists, we evaluate our ability to hold the investment, the strength of the underlying collateral and the extent to which the investment's amortized cost or cost, as appropriate, exceeds it related fair value. As of May 31, 2022 and 2021, we held approximately $ 119.0 million and $ 142.1 million in marketable equity securities, respectively. Realized and unrealized gains and losses on marketable equity securities are included in investment (income), net in the Consolidated Statements of Income. Refer to Note A(15), “Investment Expense (Income), Net,” for further details. Summarized below are the available-for-sale debt securities we held at May 31, 2022 and 2 021 that were in an unrealized loss position and that were included in accumulated other comprehensive income (loss), aggregated by the length of time the investments had been in that position: May 31, 2022 May 31, 2021 (In thousands) Fair Value Gross Fair Value Gross Total investments with unrealized losses $ 22,702 $ ( 1,342 ) $ 8,420 $ ( 184 ) Unrealized losses with a loss position for less than 12 months 16,273 ( 543 ) 6,920 ( 152 ) Unrealized losses with a loss position for more than 12 months 6,429 ( 799 ) 1,500 ( 32 ) We have reviewed all of the securities included in the table above and have concluded that we have the ability and intent to hold these investments until their cost can be recovered, based upon the severity and duration of the decline. The decline in fair value is largely due to changes in interest rates and other market conditions. We have evaluated these securities and have determined no allowance for credit losses is necessary for these investments. The net carrying values of available-for-sale debt securities at May 31, 2022, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE E — FAIR VALUE MEASUREMENTS Financial instruments recorded in the balance sheet include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt. An allowance for credit losses is established for trade accounts receivable using assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowance for doubtful collection of accounts are included in SG&A. All derivative instruments are recognized in our Consolidated Balance Sheets and measured at fair value. Changes in the fair values of derivative instruments that do not qualify as hedges and/or any ineffective portion of hedges are recognized as a gain or (loss) in our Consolidated Statements of Income in the current period. Changes in the fair value of derivative instruments used effectively as cash flow hedges were recognized in other comprehensive income (loss), along with the change in the value of the hedged item. We do not hold or issue derivative instruments for speculative purposes. The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows: Level 1 Inputs — Quoted prices for identical instruments in active markets. Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs — Instruments with primarily unobservable value drivers. The following tables present our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. In addition, with respect to our derivative assets and liabilities measured at fair value, refer to Note F – Derivatives and Hedging for discussion of their classification within the fair value hierarchy. (In thousands) Quoted Prices Significant Significant Fair Value at Available-for-sale debt securities: U.S. Treasury and other government $ - $ 25,239 $ - $ 25,239 Corporate bonds - 155 - 155 Total available-for-sale debt securities - 25,394 - 25,394 Marketable equity securities: Stocks-foreign 598 - - 598 Stocks-domestic 5,085 - - 5,085 Mutual funds - foreign - 39,139 - 39,139 Mutual funds - domestic - 74,227 - 74,227 Total marketable equity securities 5,683 113,366 - 119,049 Contingent consideration - - ( 10,529 ) ( 10,529 ) Total $ 5,683 $ 138,760 $ ( 10,529 ) $ 133,914 (In thousands) Quoted Prices Significant Significant Fair Value at Available-for-sale debt securities: U.S. Treasury and other government $ - $ 26,563 $ - $ 26,563 Corporate bonds - 182 - 182 Total available-for-sale debt securities - 26,745 - 26,745 Marketable equity securities: Stocks-foreign 768 - - 768 Stocks-domestic 6,975 - - 6,975 Mutual funds - foreign - 47,916 - 47,916 Mutual funds - domestic - 86,428 - 86,428 Total marketable equity securities 7,743 134,344 - 142,087 Contingent consideration - - ( 13,335 ) ( 13,335 ) Total $ 7,743 $ 161,089 $ ( 13,335 ) $ 155,497 Our investments in available-for-sale debt securities and marketable equity securities are valued using a market approach. The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors, including the type of instrument, whether the instrument is actively traded and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment. The contingent consideration represents the estimated fair value of the additional variable cash consideration payable in connection with recent acquisitions that is contingent upon the achievement of certain performance milestones. We estimated the fair value using expected future cash flows over the period in which the obligation is expected to be settled, and applied a discount rate that appropriately captures a market participant's view of the risk associated with the obligation, which are considered to be Level 3 inputs. During fiscal 2022, we increased our accrual by $ 3.3 million related to fair value adjustments and paid approximately $ 5.8 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during the current year. During fiscal 2021, we paid approximately $ 2.8 million for settlements of contingent consideration obligations relating to certain performance milestones that were established in prior periods and achieved during fiscal 2021. In the Consolidated Statements of Cash Flows, payments of acquisition-related contingent consideration for the amount recognized at fair value as of the acquisition date are reported in cash flows from financing activities, while payment of contingent consideration in excess of fair value as of the acquisition date, are reported in cash flows from operating activities. The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt, approximates fair value because of the short-term maturity of these financial instruments. At May 31, 2022 and 2021, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our financial instruments and long-term debt as of May 31, 2022 and 2021 are as follows: At May 31, 2022 (In thousands) Carrying Value Fair Value Cash and cash equivalents $ 201,672 $ 201,672 Marketable equity securities 119,049 119,049 Available-for-sale debt securities 25,394 25,394 Long-term debt, including current portion 2,686,609 2,618,978 At May 31, 2021 (In thousands) Carrying Value Fair Value Cash and cash equivalents $ 246,704 $ 246,704 Marketable equity securities 142,087 142,087 Available-for-sale debt securities 26,745 26,745 Long-term debt, including current portion 2,379,826 2,570,206

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging	NOTE F — DERIVATIVES AND HEDGING Derivative Instruments and Hedging Activities We are exposed to market risks, such as changes in foreign currency exchange rates and interest rates. To manage the volatility related to these exposures, from time to time, we enter into various derivative transactions. We use various types of derivative instruments, including forward contracts and swaps. We formally assess, designate and document, as a hedge of an underlying exposure, each qualifying derivative instrument that will be accounted for as an accounting hedge at inception. Additionally, we assess, both at inception and at least quarterly thereafter, whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures. Derivatives Designated as Hedges In October 2017, as a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we executed a fair va lue hedge and two cross currency swaps, in which we paid variable rate interest in Euros and receive fixed rate interest in U.S. Dollars with a combined notional amount of approximately € 85.25 million ($ 100 million U.S. Dollar equivalent), and which had a maturity date of November 2022 . This effectively converted a portion of our U.S. Dollar denominated fixed-rate debt to Euro denominated variable rate debt. The fair value hedge was recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge were recognized in interest expense in our Consolidated Statements of Income. We designated the swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. In February 2020, the fair value hedge and two cross currency swaps agreements were terminated, and we received cash in the amount of $ 9.3 million, representing the fair value of the swap and interest accrued through the date of termination. Accordingly, hedge accounting was discontinued and a hedge accounting adjustment to our Senior Notes of $ 1.5 million was recorded and is being amortized to interest expense in the Consolidated Statements of Operations through the termination of the 3.450 % Notes in November 2022. Changes in the fair value of the cross currency swaps due to spot foreign exchange rates are recorded as cumulative translation adjustment within AOCI and will remain in AOCI until either the sale or substantially complete liquidation of the hedged subsidiaries . Separately, in February 2020, as a means of mitigating the impact of currency fluctuations on our Euro investments in foreign entities, we executed a cash flow hedge and two cross currency swaps, in which we paid fixed rate interest in Euros and received variable rate interest in U.S. Dollars with a combined notional amount of approximately € 277.73 million ($ 300 million U.S. Dollar equivalent), and which had a maturity date of February 2023 . This effectively converted our U.S. Dollar denominated variable rate debt to Euro denominated fixed rate debt. The cash flow hedge was recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge were recognized in AOCI when the hedged items affected earnings. Amounts recognized in AOCI were recognized in earnings in interest expense when the hedged interest payment was accrued. We designated the swaps as net investment hedges of our net investment in our European operations under ASU 2017-12 and applied the spot method to these hedges. The changes in fair value of the derivative instruments that were designated and qualified as hedges of net investments in foreign operations were recognized in AOCI to offset the changes in the values of the net investments being hedged. In addition, in February 2020, as a means of mitigating the variability of the functional-currency-equivalent cash flows associated with the U.S. Dollar denominated term loan facility (referred to as Foreign Borrower’s Term Loan), we executed a cash flow hedge, in which we paid fixed rate interest in Euros and received variable rate interest in U.S. Dollars with a notional amount of approximately € 92.52 million ($ 100 million U.S. Dollar equivalent), and which had a maturity date of February 2023 . This effectively converted our U.S. Dollar denominated variable rate debt to Euro denominated fixed rate debt. The cash flow hedge was recognized at fair value in our Consolidated Balance Sheets, while changes in the fair value of the hedge were recognized in AOCI when the hedged items affected earnings. Amounts recorded in AOCI were recognized in earnings in interest expense when the hedged interest payment was accrued. In addition, since this currency swap was a hedge of variability of the functional-currency-equivalent cash flows of a recognized liability to be remeasured at spot exchange rates under ASC 830, an amount that offset the gain or loss arising from the remeasurement of the hedged liability was reclassified each period from AOCI to earnings as foreign exchange gain/(loss), which is a component of SG&A expenses. In May 2022, the cash flow hedges and cross currency swaps were terminated, and we received cash in the amount of $ 11.6 million, representing the fair value of the swap and interest accrued through the date of termination. Accordingly, hedge accounting was discontinued. For the cash flow hedges, a hedge accounting reserve balance within AOCI of $ 1.9 million remained and is being amortized to interest expense in the Consolidated Statements of Operations through the termination of the underlying hedged debt in February 2023. Changes in the fair value of the cross currency swaps were recorded as cumulative translation adjustment within AOCI and will remain in AOCI until either the sale or substantially complete liquidation of the hedged subsidiaries.

These contracts have not been designated as hedges; therefore, the changes in fair value of the contracts are recognized in earnings as a component of SG&A expenses. Amounts recognized in earnings did not have a material impact on our Consolidated Financial Statements for any period presented. As of May 31, 2022, and May 31, 2021, the notional amounts of the forward contract held to purchase foreign currencies was $ 238.2 million and $ 191.7 milli on, respectively. Disclosure About Derivative Instruments All of our derivative assets and liabilities measured at fair value are classified as Level 2 within the fair value hierarchy. We determine the fair value of our derivatives based on valuation methods, which project future cash flows and discount the future amounts to present value using market-based observable inputs, including interest rate curves, foreign currency rates, as well as future and basis point spreads, as applicable.

Interest at May 31, 2021 was tied to LIBOR and averaged 1.4609 % for USD denominated debt ($ 37.7 million), 1.3950 % for AUD denominated debt ($ 44.0 million) and 1.3750 % on EUR denominated debt ($ 257.9 million). At May 31, 2022 and 2021, the revolving credit facility is adjusted for debt issuance costs, net of amortization, for approximately $ 1.5 million and $ 2.6 million, respectively. (2) The $ 300.0 million face amount of the notes due 2022 is adjusted for the mark-to-market derivative asset of approximated ($ 0.3 million) and ($ 0.8 million) at May 31, 2022 and 2021, respectively. The original issue discount effectively reduced the ultimate proceeds from the financing. The effective interest rate on the notes, including the amortization of the discount, is 3.465 %. At May 31, 2022 and 2021, the notes are reduced by debt issuance costs, net of amortization, for approximately $ 0.1 million and $ 0.4 million, respectively. (3) At May 31, 2022 and 2021, the Term Loan is adjusted for deferred financing fees, net of amortization, of approximately $ 0.2 million and $ 0.5 million, respectively.

The original issue discount effectively reduced the ultimate proceeds from the financing. The effective interest rate on the notes, including the amortization of the discount, was 4.568 %. At May 31, 2022 and 2021, the notes were adjusted for debt issuance costs, net of amortization, for approximately $ 2.3 million and $ 2.7 million, respectively. (6) The $ 300.0 million face amount of the notes due 2032 is adjusted for the amortization of the original issue discount, which approximated $ 0.6 million at May 31, 2022. The original issue discount effectively reduced the ultimate proceeds from the financing. The effective interest rate on the notes, including the amortization of the discount, is 2.976 %. At May 31, 2022, the notes are adjusted for debt issuance costs, net of amortization, for approximately $ 2.9 million. (7) The $ 250.0 million face amount of the notes due 2045 is adjusted for the amortization of the original issue discount, which approximated $ 1.3 million and $ 1.4 million at May 31, 2022 and 2021, respectively. The original issue discount effectively reduced the ultimate proceeds from the financing. The effective interest rate on the notes, including the amortization of the discount, is 5.29 %. In March 2017, as a further issuance of the 5.25 % notes due 2045, we closed an offering of $ 50.0 million aggregate principal, which is adjusted for the unamortized premium received at issuance, which approximated $ 2.8 million and $ 2.9 million at May 31, 2022 and 2021, respectively. The premium effectively increased the proceeds from the financing. The effective interest rate on the $ 50.0 million notes issued March 2017 is 4.839 %.

Revolving Credit Agreement During the quarter ended November 30, 2018, we replaced our previous $ 800.0 million revolving credit agreement, which was set to expire on December 5, 2019 , with a $ 1.3 billion unsecured syndicated revolving credit facility (the “Revolving Credit Facility”), which expires on October 31, 2023 . The Revolving Credit Facility includes sublimits for the issuance of swingline loans, which are comparatively short-term loans used for working capital purposes and letters of credit. The aggregate maximum principal amount of the commitments under the Revolving Credit Facility may be expanded upon our request, subject to certain conditions, up to $ 1.5 billion. The Revolving Credit Facility is available to refinance existing indebtedness, to finance working capital and capital expenditures, and for general corporate purposes. The Revolving Credit Facility requires us to comply with various customary affirmative and negative covenants, including a leverage covenant (i.e., Net Leverage Ratio) and interest coverage ratio, which are calculated in accordance with the terms as defined by the Revolving Credit Facility. Under the terms of the leverage covenant, we may not permit our leverage ratio for total indebtedness to consolidated EBITDA for the four most recent fiscal quarters to exceed 3.75 to 1.0. During certain periods and per the terms of the Revolving Credit Facility, this ratio may be increased to 4.25 to 1.0 upon delivery of a notice to our lender requesting an increase to our maximum leverage or in connection with certain “material acquisitions.” The minimum required consolidated interest coverage ratio for EBITDA to interest expense is 3.50 to 1. The interest coverage ratio is calculated at the end of each fiscal quarter for the four fiscal quarters then ended using EBITDA as defined in the Revolving Credit Facility. As of May 31, 2022, we were in compliance with all financial covenants contained in our Revolving Credit Facility, including the leverage and interest coverage ratio covenants. At that date, our leverage ratio was 2.81 to 1, while our interest coverage ratio was 10.64 to 1. Our available liquidity under our Revolving Credit Facility stood at $ 856.2 million at May 31, 2022. Our access to funds under our Revolving Credit Facility is dependent on the ability of the financial institutions that are parties to the Revolving Credit Facility to meet their funding commitments. Those financial institutions may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time. Moreover, the obligations of the financial institutions under our Revolving Credit Facility are several and not joint and, as a result, a funding default by one or more institutions does not need to be made up by the others. Accounts Receivable Securitization Program On May 9, 2014, we entered into a $ 200.0 million accounts receivable securitization facility (the “AR Program”) which was subsequently amended on May 22, 2020 to a maximum availability of $ 250.0 million and an extended facility termination date of May 21, 2021 . On March 18, 2021, we amended the AR Program to a maximum availability of $ 250 million during all borrowing periods and an extended facility termination date of May 21, 2024 . The AR Program was entered into pursuant to (1) a second amended and restated receivables sales agreement, dated as of May 9, 2014, and subsequently amended on August 29, 2014; November 3, 2015; December 31, 2016; March 31, 2017; and June 5, 2020 (the “Sale Agreement”), among certain of our subsidiaries (the “Originators”), and RPM Funding Corporation, a special purpose entity (the “SPE”) whose voting interests are wholly owned by us, and (2) an amended and restated receivables purchase agreement, dated as of May 9, 2014 and subsequently amended on February 25, 2015 and May 2, 2017, May 22, 2020 and March 18, 2021 (the “Purchase Agreement”), among the SPE, certain purchasers from time to time party thereto (the “Purchasers”), and PNC Bank, National Association as administrative agent. Under the Sale Agreement, the Originators may, during the term thereof, sell specified accounts receivable to the SPE, which may in turn, pursuant to the Purchase Agreement, transfer an undivided interest in such accounts receivable to the Purchasers. Once transferred to the SPE, such receivables are owned in their entirety by the SPE and are not available to satisfy claims of our creditors or creditors of the originating subsidiaries until the obligations owing to the participating banks have been paid in full. We indirectly hold a 100 % economic interest in the SPE and will, along with our subsidiaries, receive the economic benefit of the AR Program. The transactions contemplated by the AR Program do not constitute a form of off-balance sheet financing and will be fully reflected in our financial statements. The maximum availability under the AR Program is $ 250.0 million. Availability is further subject to changes in the credit ratings of our customers, customer concentration levels or certain characteristics of the accounts receivable being transferred and, therefore, at certain times, we may not be able to fully access the $ 250.0 million of funding available under the AR Program. As of May 31, 2022, there was no outstanding balance under the AR Program, which compares with the maximum availability on that date of $ 250.0 million. The interest rate under the Purchase Agreement is based on the Alternate Base Rate, LIBOR Market Index Rate, one-month LIBOR or LIBOR for a specified tranche period, as selected by us, plus in each case, a margin of 0.85 %. In addition, as set forth in an Amended and Restated Fee Letter, dated March 18, 2021 (the “Fee Letter”), the SPE is obligated to pay a monthly unused commitment fee to the Purchasers based on the daily amount of unused commitments under the Agreement, which ranges from 0.30 % to 0.50 % based on usage. The AR Program contains various customary affirmative and negative covenants and also contains customary default and termination provisions. Our failure to comply with the covenants described above and other covenants contained in the Revolving Credit Facility section above could result in an event of default under that agreement, entitling the lenders to, among other things, declare the entire amount outstanding under the Revolving Credit Facility to be due and payable. The instruments governing our other outstanding indebtedness generally include cross-default provisions that provide that, under certain circumstances, an event of default that results in acceleration of our indebtedness under the Revolving Credit Facility will entitle the holders of such other indebtedness to declare amounts outstanding immediately due and payable. 3.45% Notes due 2022 On October 23, 2012, we sold $ 300 million aggregated principal amount of 3.45 % Notes due 2022. The net proceeds of $ 297.7 million from this offering were used to repay short-term borrowings outstanding under our revolving credit facility. Term Loan Facility Credit Agreement On February 21, 2020, we and our subsidiary, RPM Europe Holdco B.V. (formerly “RPM New Horizons Netherlands, B.V”). (the “Foreign Borrower”), entered into an unsecured syndicated term loan facility credit agreement (the “New Credit Facility”) with the lenders party thereto and PNC Bank, National Association, as administrative agent for the lenders. The New Credit Facility provides for a $ 300 million term loan to us and a $ 100 million term loan to the Foreign Borrower (together, the “Term Loans”), each of which was fully advanced on the closing date. The Term Loans mature on February 21, 2023 , with no scheduled amortization before that date, and the Term Loans may be prepaid at any time without penalty or premium. We agreed to guarantee all obligations of the Foreign Borrower under the New Credit Facility. The proceeds of the Term Loans were used to repay a portion of the outstanding borrowings under our revolving credit facility. During fiscal 2021, the New Credit Facility was amended to replace RPM New Horizons Netherlands, B.V. with RPM Europe Holdco B.V. In February of 2020, we, and the Foreign Borrower entered into multiple derivative arrangements that effectively fixed interest payment obligations on the entire principal amount of the Term Loans through their maturity. In May of 2022, we terminated the derivative arrangements and paid down the $ 100 million term loan to the Foreign Borrower. For information regarding our derivative arrangements, see Note F, "Derivatives and Hedging" to the Consolidated Financial Statements. The $ 300 million Term Loan still outstanding bears an interest at a variable base rate plus a spread determined by our debt rating. The New Credit Facility contains customary covenants, including but not limited to, limitations on our ability, and in certain instances, our subsidiaries’ ability, to incur liens, make certain investments, or sell or transfer assets. Additionally, we may not permit (i) our consolidated interest coverage ratio to be less than 3.5 to 1.0, or (ii) our leverage ratio (defined as the ratio of total indebtedness, less unencumbered cash and cash equivalents in excess of $ 50 million, to consolidated EBITDA for the four most recent fiscal quarters) to exceed 3.75 to 1.0. During certain periods this ratio may be increased to 4.25 to 1.0 upon delivery of a notice to our lender requesting an increase to our maximum leverage or in connection with certain "material acquisitions." See “Revolving Credit Agreement” above for details on our compliance with all significant financial covenants at May 31, 2022. 5.250% Notes due 2045 and 3.750% Notes due 2027 On March 2, 2017, we issued $ 50.0 million aggregate principal amount of 5.250 % Notes due 2045 (the “2045 Notes”) and $ 400.0 million aggregate principal amount of 3.750 % Notes due 2027 (the “2027 Notes”).

The proceeds from the 2029 Notes were used to repay a portion of the outstanding borrowings under our revolving credit facility and for general corporate purposes. Interest on the 2029 Notes accrues from February 27, 2019 and is payable semiannually in arrears on March 1 st and September 1 st of each year, beginning September 1, 2019, at a rate of 4.550% per year.

The proceeds from the 2032 notes were used to repay a portion of the outstanding borrowings under our revolving credit facility and for general corporate purposes. Interest on the Notes accrues from January 25, 2022 and will be payable semiannually in arrears on January 15 and July 15 of each year, beginning July 15, 2022, at a rate of 2.95% per year. The notes mature on January 15, 2032 . The indenture governing this indebtedness includes cross-acceleration provisions.

The proceeds from the 2048 Notes were used to repay $ 250.0 million in principal amount of unsecured 6.50 % senior notes due February 15, 2018 , and for general corporate purposes. Interest on the 2048 Notes accrues from December 20, 2017 and is payable semiannually in arrears on January 15 th and July 15 th of each year, beginning July 15, 2018, at a rate of 4.250% per year. The 2048 Notes mature on January 15, 2048 . The indenture governing this indebtedness includes cross-acceleration provisions.

Also, as of May 31, 2022, we had foreign tax credit carryforwards of $ 35.8 million, which expire at various dates through fiscal 2032 . Additionally, as of May 31, 2022, we had approximately $ 1.4 million of net tax benefits associated with state net operating loss carryforwards and state tax credit carryforwards, some of which expire at various dates beginning in fiscal 2023 . Also, as of May 31, 2022, we had foreign net operating loss carryforwards of approximately $ 116.8 million, of which approximately $ 5.0 million will expire at various dates beginning in fiscal 2023 and approximately $ 111.8 million that have an indefinite carryforward period. Additionally, as of May 31, 2022, we had foreign capital loss carryforwards of approximately $ 23.8 million that can be carried forward indefinitely. When evaluating the realizability of deferred income tax assets, we consider, among other items, whether a jurisdiction has experienced cumulative pretax losses and whether a jurisdiction will generate the appropriate character of income to recognize a deferred income tax asset. More specifically, if a jurisdiction experiences cumulative pretax losses for a period of three years, including the current fiscal year, or if a jurisdiction does not have sufficient income of the appropriate character in the relevant carryback or projected carryforward periods, we generally conclude that it is more likely than not that the respective deferred tax asset will not be realized unless factors such as expected operational changes, availability of prudent and feasible tax planning strategies, reversal of taxable temporary differences or other information exists that would lead us to conclude otherwise. If, after we have evaluated these factors, the deferred income tax assets are not expected to be realized within the carryforward or carryback periods allowed for that jurisdiction, we would conclude that a valuation allowance is required. Total valuation allowances of approximately $ 30.5 million and $ 64.7 million have b een recorded as of May 31, 2022 and 2021, respectively. These recorded valuation allowances relate primarily to U.S. capital losses, state net operating losses and certain foreign net operating losses, and net foreign deferred tax assets. The year-over-year decrease in valuation allowances includes a $ 21.3 million reversal attributable to U.S. foreign tax credit carryforwards and a $ 5.6 million reversal related to certain Non-U.S. tax loss carryforwards. Additionally, certain U.S. capital loss carryforwards which were offset by a valuation allowance expired as of May 31, 2022. The following table reconciles income tax expense (benefit) computed by applying the U.S. statutory federal income tax rate against income (loss) before income taxes to the provision (benefit) for income taxes: Year Ended May 31, 2022 2021 2020 (In thousands, except percentages) Income tax expense at the U.S. statutory federal income tax rate $ 127,428 $ 140,372 $ 85,630 Foreign rate differential and other foreign tax adjustments 6,278 11,942 3,433 State and local income taxes, net 20,393 18,625 11,651 Impact of GILTI provisions 1,709 1,598 3,051 Nondeductible business expense 532 616 2,005 Valuation allowance ( 32,720 ) ( 4,389 ) 14,008 Deferred tax liability for unremitted foreign earnings ( 10,686 ) 5,348 ( 5,527 ) Changes in unrecognized tax benefits ( 1,682 ) ( 1,847 ) 1,292 Equity-based compensation ( 1,776 ) ( 8,651 ) ( 5,162 ) FY19 GILTI impact of issued regulations - - ( 4,348 ) Other 4,857 1,324 ( 3,351 ) Provision for Income Tax Expense $ 114,333 $ 164,938 $ 102,682 Effective Income Tax Rate 18.8 % 24.7 % 25.2 % Uncertain income tax positions are accounted for in accordance with ASC 740. The following table summarizes the activity related to unrecognized tax benefits: (In millions) 2022 2021 2020 Balance at June 1 $ 7.5 $ 9.0 $ 8.1 Additions for tax positions of prior years - - 2.0 Reductions for tax positions of prior years ( 1.7 ) ( 1.8 ) ( 0.9 ) Foreign currency translation ( 0.1 ) 0.3 ( 0.2 ) Balance at May 31 $ 5.7 $ 7.5 $ 9.0 The total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, was $ 5.6 million at May 31, 2022, $ 7.0 million at May 31, 2021 and $ 8.6 million at May 31, 2020. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. At May 31, 2022, 2021 and 2020, the accrual for interest and penalties was $ 3.2 million, $ 2.9 million and $ 2.9 million, respectively. Unrecognized tax benefits, including interest and penalties, have been classified as other long-term liabilities unless expected to be paid in one year. We file income tax returns in the United States and in various state, local and foreign jurisdictions. With limited exceptions, we are subject to federal, state and local, or non-U.S. income tax examinations by tax authorities for fiscal 2015 through 2022. We are currently under examination, or have been notified of an upcoming tax examination, for various non-U.S. and domestic state and local jurisdictions. Although it is possible that certain tax examinations could be resolved during the next 12 months, the timing and outcomes are uncertain. Our deferred tax liability for unremitted foreign earnings was $ 3.0 million as of May 31, 2022, which represents our estimate of the tax cost associated with the deemed remittance of $ 431.4 million of foreign earnings that are not considered to be permanently reinvested. We have not provided for U.S. income taxes or foreign withholding taxes on the remaining $ 1.4 billion of foreign unremitted earnings because such earnings have been retained and reinvested by the foreign subsidiaries as of May 31, 2022. Accordingly, no provision has been made for U.S. income taxes or foreign withholding taxes, which may become payable if the remaining unremitted earnings of foreign subsidiaries were distributed to the United States. Due to the uncertainties and complexities involved in the various options for repatriation of foreign earnings, it is not practical to calculate the deferred taxes associated with the remaining foreign earnings.

Stock Repurchase Program

Stock Repurchase Program	May 31, 2022
Equity [Abstract]
Stock Repurchase Program	NOTE I — STOCK REPURCHASE PROGRAM On January 8, 2008 , we announced our authorization of a stock repurchase program under which we may repurchase shares of RPM International Inc. common stock at management’s discretion. As announced on November 28, 2018, our goal was to return $ 1.0 billion in capital to stockholders by May 31, 2021 through share repurchases and the retirement of our convertible note during fiscal 2019. On April 16, 2019, after taking into account share repurchases under our existing stock repurchase program to date, our Board of Directors authorized the repurchase of the remaining $ 600.0 million in value of RPM International Inc. common stock by May 31, 2021. As previously announced, given macroeconomic uncertainty resulting from the Covid pandemic, we had suspended stock repurchases under the program, but in January 2021, our Board of Directors authorized the resumption of the stock repurchases. At the time of resuming the program, $ 469.7 million of shares of common stock remained available for repurchase. The Board of Directors also extended the stock repurchase program beyond its original May 31, 2021 expiration date until such time that the remaining $ 469.7 million of capital has been returned to our stockholders. As a result, we may repurchase shares from time to time in the open market or in private transactions at various times and in amounts and for prices that our management deems appropriate, subject to insider trading rules and other securities law restrictions. The timing of our purchases will depend upon prevailing market conditions, alternative uses of capital and other factors. We may limit or terminate the repurchase program at any time. During the fiscal year ended May 31, 2022, we repurchased 601,155 shares of our common stock at a cost of approximately $ 52.5 million, or an average cost of $ 87.33 per share, under this program. During the fiscal year ended May 31, 2021, we repurchased 594,061 shares of our common stock at a cost of approximately $ 50.0 million, or an average cost of $ 84.09 per share, under this program. During the fiscal year ended May 31, 2020, we repurchased 2,041,847 shares of our common stock at a cost of approximately $ 125.0 million, or an average cost of $ 61.22 per share, under this program. The maximum dollar amount that may yet be repurchased under our stock repurchase program was approximately $ 367.3 million at May 31, 2022.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended
Stock-Based Compensation	May 31, 2022
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	NOTE J — STOCK-BASED COMPENSATION Stock-based compensation represents the cost related to stock-based awards granted to our associates and directors; these awards include restricted stock, restricted stock units, performance stocks, performance stock units and SARs. We grant stock-based incentive awards to our associates and our directors under various share-based compensation plans. The plan that is active or provides for stock option grants or share-based payment awards is the Amended and Restated 2014 Omnibus Equity and Incentive Plan (the “2014 Omnibus Plan”), which includes provisions for grants of restricted stock, restricted stock units, performance stock, performance stock units and SARs. Other plans, which provide for restricted stock grants only, include the 2003 Restricted Stock Plan for Directors (the “2003 Plan”) and the 2007 Restricted Stock Plan (the “2007 Plan”). At May 31, 2022, the shares available for grant out of the 2003 Plan and the 2007 Plan have been exhausted, and all future grants will be issued from the 2014 Omnibus Plan. We measure stock-based compensation cost at the date of grant, based on the estimated fair value of the award. We recognize the cost as expense on a straight-line basis (net of estimated forfeitures) over the related vesting period. The following table represents total stock-based compensation expense included in our Consolidated Statements of Income: Year Ended May 31, 2022 2021 2020 (In thousands) Stock-based compensation expense, included in SG&A $ 40,114 $ 40,926 $ 19,789 Stock-based compensation expense, included in restructuring expense 630 47 116 Total stock-based compensation cost 40,744 40,973 19,905 Income tax (benefit) ( 5,621 ) ( 6,877 ) ( 2,784 ) Total stock-based compensation cost, net of tax $ 35,123 $ 34,096 $ 17,121 SARs SARs are awards that allow our associates to receive shares of our common stock at a fixed price. We grant SARs at an exercise price equal to the stock price on the date of the grant. The fair value of SARs granted is estimated as of the date of grant using a Black-Scholes option-pricing model. The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected life of options granted is derived from the input of the option-pricing model and represents the period of time that options granted are expected to be outstanding. Expected volatility rates are based on historical volatility of shares of our common stock. The following is a summary of our weighted-average assumptions related to SARs grants made during the last three fiscal years: Year Ended May 31, 2022 2021 2020 Risk-free interest rate 0.9 % 0.4 % 1.9 % Expected life of option 6.0 yrs 6.5 yrs 6.5 yrs Expected dividend yield 1.8 % 1.8 % 2.3 % Expected volatility rate 24.1 % 24.0 % 22.4 % The 2014 Omnibus Plan was approved by our stockholders on October 9, 2014 , and amendments to the 2014 Omnibus Plan were subsequently approved by our stockholders in 2018 and 2019. The 2014 Omnibus Plan provides us with the flexibility to grant a wide variety of stock and stock-based awards, as well as dollar-denominated performance-based awards, and is intended to be the primary stock-based award program for covered associates. SARs are issued at fair value at the date of grant, have up to ten-year terms and have graded-vesting terms over four years . Compensation cost for these awards is recognized on a straight-line basis over the related vesting period. Currently all SARs outstanding are to be settled with stock. As of May 31, 2022, there were 2,300,000 SARs outstanding. The following tables summarize option and share-based payment activity (including SARs) under these plans during the fiscal year ended May 31, 2022: 2022 Share-Based Payments Weighted Number of (Shares in thousands) Balance at June 1, 2021 $ 59.28 2,005 Options granted 86.93 340 Options exercised 69.71 ( 45 ) Balance at May 31, 2022 63.16 2,300 Exercisable at May 31, 2022 $ 55.88 1,490 SARs 2022 2021 2020 (In thousands, except per share amounts) Weighted-average grant-date fair value per SAR $ 16.72 $ 14.38 $ 11.59 Intrinsic value of options exercised $ 13.77 $ 8.80 $ 9.62 Tax benefit from options exercised $ 88 $ 8,821 $ 5,936 Fair value of SARS vested $ 13.49 $ 12.59 $ 12.27 At May 31, 2022, the aggregate intrinsic value and weighted-average remaining contractual life of options outstanding was $ 57.4 million and 5.87 years, respectively, while the aggregate intrinsic value and weighted-average remaining contractual life of options exercisable was $ 48.0 million and 4.65 years, respectively. At May 31, 2022, the total unamortized stock-based compensation expense related to SARs that were previously granted was $ 7.8 million, which is expected to be recognized over 2.50 years. We anticipate that approximately 2.3 million shares at a weighted-average exercise price of $ 63.14 and a weighted-average remaining contractual term of 5.87 years will ultimately vest under these plans. Restricted Stock Plans We also grant stock-based awards, which may be made in the form of restricted stock, restricted stock units, performance stock and performance stock units. These awards are granted to eligible associates or directors, and entitle the holder to shares of our common stock as the award vests. The fair value of the awards is determined and fixed based on the stock price at the date of grant. A description of our restricted stock plans follows. Under the 2014 Omnibus Plan, a total of 6,000,000 shares of our common stock may be subject to awards. Of those issuable shares, up to 3,000,000 shares of common stock may be subject to “full-value” awards. In October 2019, shareholders approved an amendment to the 2014 Omnibus Plan making an additional 5,000,000 shares of common stock subject to awards. Of those additional issuable shares, 2,250,000 shares may be subject to “full-value” awards similar to those issued under the 2014 Omnibus Plan. The following table summarizes the share-based performance-earned restricted stock (“PERS”) and performance stock units (“PSUs”) activity during the fiscal year ended May 31, 2022: Weighted-Average Grant-Date Fair Value 2022 (Shares in thousands) Balance at June 1, 2021 $ 69.13 1,116 Shares granted 86.88 432 Shares forfeited 67.94 ( 125 ) Shares vested 63.65 ( 313 ) Balance at May 31, 2022 $ 77.71 1,110 The weighted-average grant-date fair value was $ 86.88 , $ 80.67 and $ 63.52 for the fiscal years ended May 31, 2022, 2021 and 2020, respectively. The restricted stock and performance stock cliff vest after three years . Nonvested restricted shares of common stock under the 2014 Omnibus Plan are eligible for dividend payments, while performance stock units are not eligible for dividend payments. At May 31, 2022, remaining unamortized deferred compensation expense for performance-earned restricted stock totaled $ 22.4 million. The remaining amount is being amortized over the applicable vesting period for each participant. On July 18, 2019, our Compensation Committee granted in the aggregate 178,000 Performance Stock Units (the “2019 PSUs”) to certain executives at a weighted-average grant-date price of $ 62.17 per PSU. The awards are contingent upon the level of attainment of performance goals for the three-year performance period from June 1, 2019 ending May 31, 2022. Vesting of 50 % of the 2019 PSUs relates to compounded annualized growth rates in adjusted revenue for the period, and the vesting of the remaining 50 % relates to an increase in EBIT margin, measured at the end of the three-year performance period. The number of PSUs that may vest with respect to the achievement of the performance goals may range from 0 % to 200 % of the PSUs granted under this program. Compensation cost for these awards has been recognized on a straight-line basis over the related performance period, with consideration given to the probability of attaining the performance goals. As of May 31, 2022, there were 153,000 2019 PSUs outstanding and the expense has been fully recognized, in line with the final results achieved for the three-year performance period as compared to the performance goals. On July 22, 2020, our Compensation Committee granted in the aggregate 225,500 Performance Stock Units (the “2020 PSUs”) to certain executives at a weighted-average grant-date price of $ 78.49 per PSU. The awards are contingent upon the level of attainment of performance goals for the three-year performance period from June 1, 2020 ending May 31, 2023. Vesting of 50 % of the 2020 PSUs relates to compounded annualized growth rates in adjusted revenue for the period, and the vesting of the remaining 50 % relates to an increase in EBIT margin, measured at the end of the three-year performance period. The number of PSUs that may vest with respect to the achievement of the performance goals may range from 0 % to 200 % of the PSUs granted under this program. Compensation cost for these awards has been recognized on a straight-line basis over the related performance period, with consideration given to the probability of attaining the performance goals. As of May 31, 2022, there were 196,250 2020 PSUs outstanding and $ 7.9 million unamortized stock-based compensation, which is expected to be recognized over a weighted average period of 1.0 years. On July 21, 2021, our Compensation Committee granted in the aggregate 157,700 Performance Stock Units (the “2021 PSUs”) to certain executives at a weighted-average grant-date price of $ 86.93 per PSU. The awards are contingent upon the level of attainment of performance goals for the three-year performance period from June 1, 2021 ending May 31, 2024. Vesting of 50 % of the 2021 PSUs relates to compounded annualized growth rates in adjusted revenue for the period, and the vesting of the remaining 50 % relates to an increase in EBIT margin, measured at the end of the three-year performance period. The number of PSUs that may vest with respect to the achievement of the performance goals may range from 0 % to 200 % of the PSUs granted under this program. Compensation cost for these awards has been recognized on a straight-line basis over the related performance period, with consideration given to the probability of attaining the performance goals. As of May 31, 2022, there were 147,900 2021 PSUs outstanding and $ 8.8 million unamortized stock-based compensation, which is expected to be recognized over a weighted average period of 2.0 years. The 2003 Plan was approved on October 10, 2003 by our stockholders, and was established primarily for the purpose of recruiting and retaining directors, and to align the interests of directors with the interests of our stockholders. Only directors who are not our associates are eligible to participate. Under the 2003 Plan, up to 500,000 shares of our common stock may be awarded, with awards cliff vesting over a three-year period. At May 31, 2022, the shares available for grant out of the 2003 Plan have been exhausted, and all future grants will be issued from the 2014 Omnibus Plan. The following table summarizes the share-based activity under the 2003 Plan and 2014 Omnibus Plan related to directors during fiscal 2022: Weighted-Average Grant-Date Fair Value 2022 (Shares in thousands) Balance at June 1, 2021 $ 71.19 56 Shares granted to directors 81.53 18 Shares vested 60.50 ( 18 ) Balance at May 31, 2022 $ 77.95 56 The weighted-average grant-date fair value was $ 81.53 , $ 87.35 and $ 67.26 for the fiscal years ended May 31, 2022, 2021 and 2020, respectively. Unamortized deferred compensation expense relating to restricted stock grants for directors of $ 2.0 million at May 31, 2022, is being amortized over the applicable remaining vesting period for each director. Nonvested restricted shares of common stock under the 2003 Plan are eligible for dividend payments. At May 31, 2022, the shares available for grant out of the 2003 Plan have been exhausted, and all future grants will be issued from the 2014 Omnibus Plan. During fiscal 2022, a total of 23,869 shares were awarded under the 2014 Omnibus Plan to certain associates as supplemental retirement benefits, generally subject to forfeiture. The shares vest upon the latter of attainment of age 55 and the fifth anniversary of the May 31 st immediately preceding the date of the grant. The following table sets forth such awards for the year ended May 31, 2022: Weighted-Average Grant-Date Fair Value 2022 (Shares in thousands) Balance at June 1, 2021 $ 37.89 418 Shares granted 86.93 24 Shares exercised 44.91 ( 56 ) Balance at May 31, 2022 $ 40.08 386 The weighted-average grant-date fair value was $ 86.93 , $ 78.49 and $ 62.17 for the fiscal years ended May 31, 2022, 2021 and 2020, respectively. As noted above, as of May 31, 2022, no shares remain avai lable for future grant under the 2007 Plan, and future issuances of shares as supplemental retirement benefits are made under the 2014 Omnibus Plan. At May 31, 2022, unamortized stock-based compensation expense of $ 0.1 million and $ 4.3 million relating to the 2007 Plan and the 2014 Omnibus Plan, respectively, are being amortized over the applicable vesting period associated with each participant. The following table summarizes the activity for all nonvested restricted shares during the year ended May 31, 2022: Weighted-Average Grant-Date Fair Number of Value Shares (Shares in thousands) Balance at June 1, 2021 $ 67.65 1,333 Granted 86.68 474 Vested 61.51 ( 441 ) Forfeited 73.69 ( 70 ) Balance at May 31, 2022 $ 76.38 1,296 The remaining weighted-average contractual term of nonvested restricted shares at May 31, 2022 is the same as the period over which the remaining cost of the awards will be recognized, which is approximately 2.09 years. The fair value of the nonvested restricted share awards have been calculated using the market value of the shares on the date of issuance. For the years ended May 31, 2022, 2021 and 2020, the weighted-average grant-date fair value for restricted share grants was $ 86.68 , $ 80.77 and $ 63.62 , respectively. The total fair value of shares that vested during the years ended May 31, 2022, 2021 and 2020 was $ 27.2 million, $ 12.5 million and $ 20.8 million, respectively. We anticipate that approximately 1.30 million shares at a weighted-average grant-date fair value of $ 76.38 and a weighted-average remaining contractual term of 2.09 years will ultimately vest, based upon the unique terms and participants of each plan. 441,594 shares of restricted stock were vested during the year ended May 31, 2022, with 250,329 restricted shares vested during the year ended May 31, 2021. The total intrinsic value of restricted shares converted during the years ended May 31, 2022, 2021 and 2020 was $ 33.0 million, $ 20.7 million and $ 26.8 million , respectively. Total unrecognized compensation cost related to all nonvested awards of restricted shares of common stock was $ 45.5 million as of May 31, 2022. That cost is expected to be recognized over a weighted-average period of 2.09 years. We did not receive any cash from associates as a result of associate vesting and release of restricted shares for the year ended May 31, 2022.

Leases

Leases	May 31, 2022
Leases [Abstract]
Leases	NOTE M — LEASES We have leases for manufacturing facilities, warehouses, office facilities, equipment, and vehicles, which are primarily classified and accounted for as operating leases. We have a small portfolio of finance leases, which are not material to our Consolidated Financial Statements. Some leases include one or more options to renew, generally at our sole discretion, with renewal terms that can extend the lease term from one to five years or more. In addition, certain leases contain termination options, where the rights to terminate are held by either us, the lessor, or both parties. These options to extend or terminate a lease are included in the lease terms when it is reasonably certain that we will exercise that option. We have made an accounting policy election not to recognize ROU assets and lease liabilities for leases with a term of twelve months or less, with no renewal option that we are reasonably certain to exercise. ROU assets and lease liabilities are recognized based on the present value of the fixed and in-substance fixed lease payments over the lease term at the commencement date. The ROU assets also include any initial direct costs incurred and lease payments made at or before the commencement date and are reduced by lease incentives. We use our incremental borrowing rate as the discount rate to determine the present value of the lease payments for leases, as our leases do not have readily determinable implicit discount rates. Our incremental borrowing rate is the rate of interest that we would have to borrow on a collateralized basis over a similar term and amount in a similar economic environment. We determine the incremental borrowing rates for our leases by adjusting the local risk-free interest rate with a credit risk premium corresponding to our credit rating. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease expense is recognized as a combination of the amortization expense for the ROU assets and interest expense for the outstanding lease liabilities using the discount rate discussed above. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any significant residual value guarantees or material restrictive covenants. Income from subleases was not significant for any period presented. The following represents our lease costs as of May 31, 2022 and 2021: May 31, 2022 2021 2020 (In thousands) Operating lease expense $ 78,479 $ 76,581 $ 73,665 Variable lease expense 10,795 9,292 7,243 Short-term lease expense 2,132 2,022 2,583 The following represents our supplemental cash flow, balance sheet, and other required disclosures as of May 31, 2022 and 2021: May 31, 2022 2021 (In thousands) Operating cash outflows from operating leases $ 73,566 $ 71,257 Leased assets obtained in exchange for operating lease obligations 79,150 69,375 Current portion of operating leases within Other Accrued Liabilities $ 58,292 $ 58,563 Weighted average remaining lease term for operating leases (in years) 8.5 8.6 Weighted average discount rate for operating leases 3.3 % 3.4 % The following represents our future undiscounted cash flows for each of the next five years and thereafter and reconciliation to the lease liabilities, as of May 31, 2022: (In thousands) Year ending May 31, Operating Leases 2023 $ 67,339 2024 56,556 2025 44,471 2026 37,254 2027 33,100 Thereafter 137,356 Total lease payments $ 376,076 Less imputed interest 52,645 Total present value of lease liabilities $ 323,431

Gain On Sale Of Assets [Abstract]
(Gain) on Sales of Assets, Net	NOTE N - (GAIN) ON SALES OF ASSETS, NET During the fiscal year ended May 31, 2022, we recognized net gains of $ 52.0 million on the sales of certain real property assets. Most significantly, certain real property assets for the Toronto, Ontario location, within our CPG segment, were sold on September 15, 2021 for $ 49.8 million. We received $ 48.0 million of net proceeds after adjustments and expenses and recognized a gain on sale of $ 41.9 million. The purpose of the transaction was to generate cash by monetizing a real estate market opportunity. In conjunction with the sale, we executed a leaseback agreement commencing September 15, 2021 and expiring on September 14, 2024 . During the second quarter of fiscal 2022, the lease was classified as an operating lease with total future minimum payments during the initial term of the lease of approximately $ 3.4 million. An incremental borrowing rate of 1.3 % was used to determine the ROU asset. We recorded a $ 3.7 million ROU asset in Operating lease right-of-use assets and corresponding liabilities in the same amount in Operating lease liabilities in our Consolidated Balance Sheets during the second quarter of fiscal 2022.

Pension Plans

Retirement Benefits [Abstract]
Pension Plans	NOTE O — PENSION PLANS We sponsor several pension plans for our associates, including our principal plan (the “Retirement Plan”), which is a non-contributory defined benefit pension plan covering substantially all domestic non-union associates. Pension benefits are provided for certain domestic union associates through separate plans. Associates of our foreign subsidiaries receive pension coverage, to the extent deemed appropriate, through plans that are governed by local statutory requirements. The Retirement Plan provides benefits that are based upon years of service and average compensation with accrued benefits vesting after five years . Benefits for union associates are generally based upon years of service, or a combination of years of service and average compensation. Our pension funding policy considers contributions in an amount on an annual basis that can be deducted for federal income tax purposes, using a different actuarial cost method and different assumptions from those used for financial reporting. For the fiscal year ending May 31, 2023, we are required to contribute approximately $ 1.3 million to the retirement plans in the United States and approximately $ 4.9 million to our foreign plans. During the year, we will evaluate whether to make additional contributions. During fiscal 2022, we contributed $ 65.6 million to the pension plans in the United States which was in excess of the required contribution of $ 1.0 million but serves to improve the funded status of the plans. Net periodic pension cost consisted of the following for the year ended May 31: U.S. Plans Non-U.S. Plans (In thousands) 2022 2021 2020 2022 2021 2020 Service cost $ 47,655 $ 44,520 $ 39,425 $ 5,023 $ 6,355 $ 5,400 Interest cost 15,366 15,223 20,415 4,948 5,308 4,842 Expected return on plan assets ( 41,544 ) ( 33,115 ) ( 34,291 ) ( 7,691 ) ( 7,286 ) ( 7,118 ) Amortization of: Prior service cost (credit) 5 8 9 ( 139 ) ( 150 ) ( 36 ) Net actuarial losses recognized 16,900 30,005 18,516 465 2,377 2,029 Curtailment/settlement losses 16 - - 7 356 86 Net Pension Cost $ 38,398 $ 56,641 $ 44,074 $ 2,613 $ 6,960 $ 5,203 The changes in benefit obligations and plan assets, as well as the funded status of our pension plans at May 31, 2022 and 2021, were as follows: U.S. Plans Non-U.S. Plans (In thousands) 2022 2021 2022 2021 Benefit obligation at beginning of year $ 822,073 $ 762,739 $ 232,028 $ 210,278 Service cost 47,655 44,520 5,023 6,355 Interest cost 15,366 15,223 4,948 5,308 Benefits paid ( 59,795 ) ( 64,139 ) ( 7,657 ) ( 9,248 ) Participant contributions - - 1,138 1,140 Plan amendments - - 293 - Plan settlements/curtailments ( 190 ) - ( 1,330 ) ( 2,342 ) Actuarial (gains)/losses ( 121,374 ) 63,730 ( 34,638 ) ( 7,774 ) Premiums paid - - ( 107 ) ( 103 ) Currency exchange rate changes - - ( 17,164 ) 28,414 Benefit Obligation at End of Year $ 703,735 $ 822,073 $ 182,534 $ 232,028 Fair value of plan assets at beginning of year $ 672,377 $ 516,550 $ 239,853 $ 194,874 Actual (loss) return on plan assets ( 61,036 ) 157,702 ( 25,430 ) 21,350 Employer contributions 65,604 62,264 4,626 7,119 Participant contributions - - 1,138 1,140 Benefits paid ( 59,795 ) ( 64,139 ) ( 7,657 ) ( 9,248 ) Premiums paid - - ( 107 ) ( 103 ) Plan settlements/curtailments ( 190 ) - ( 1,330 ) ( 2,327 ) Currency exchange rate changes - - ( 17,718 ) 27,048 Fair Value of Plan Assets at End of Year $ 616,960 $ 672,377 $ 193,375 $ 239,853 (Deficit)/Surplus of plan assets versus benefit obligations at end of year $ ( 86,775 ) $ ( 149,696 ) $ 10,841 $ 7,825 Net Amount Recognized $ ( 86,775 ) $ ( 149,696 ) $ 10,841 $ 7,825 Accumulated Benefit Obligation $ 610,433 $ 702,315 $ 172,141 $ 217,012 The fair value of the assets held by our pension plans has decreased at May 31, 2022 since our previous measurement date at May 31, 2021, due to market returns. Total plan liabilities have decreased due to an increase in the discount rate used to value the liability. We have decreased our recorded liability for the net underfunded status of our pension plans. We expect pension expense in fiscal 2023 to be higher when compared to our fiscal 2022 expense level due to a reduction in expected return on plan assets and higher interest costs which will only be partially offset by a reduction in service cost due to higher discount rates. Any future declines in the value of our pension plan assets or increases in our plan liabilities could require us to increase our recorded liability for the net underfunded status of our pension plans and could also require accelerated and higher cash contributions to our pension plans. Amounts recognized in the Consolidated Balance Sheets for the years ended May 31, 2022 and 2021 are as follows: U.S. Plans Non-U.S. Plans (In thousands) 2022 2021 2022 2021 Noncurrent assets $ 77 $ - $ 22,399 $ 22,698 Current liabilities ( 8 ) ( 8 ) ( 443 ) ( 471 ) Noncurrent liabilities ( 86,844 ) ( 149,688 ) ( 11,115 ) ( 14,402 ) Net Amount Recognized $ ( 86,775 ) $ ( 149,696 ) $ 10,841 $ 7,825 The following table summarizes the relationship between our plans' benefit obligations and assets: U.S. Plans 2022 2021 (In thousands) Benefit Plan Assets Benefit Plan Assets Plans with projected benefit obligations in excess of plan assets $ 702,511 $ 615,659 $ 822,073 $ 672,377 Plans with accumulated benefit obligations in excess of plan assets 10,542 10,024 702,315 672,377 Plans with assets in excess of projected benefit obligations 1,224 1,301 - - Plans with assets in excess of accumulated benefit obligations 599,891 606,936 - - Non-U.S. Plans 2022 2021 (In thousands) Benefit Plan Assets Benefit Plan Assets Plans with projected benefit obligations in excess of plan assets $ 36,607 $ 25,049 $ 45,294 $ 30,421 Plans with accumulated benefit obligations in excess of plan assets 32,808 22,844 43,522 30,421 Plans with assets in excess of projected benefit obligations 145,927 168,326 186,734 209,432 Plans with assets in excess of accumulated benefit obligations 139,333 170,531 173,490 209,432 The following table presents the pretax net actuarial loss and prior service (cost) recognized in accumulated other comprehensive income (loss) not affecting retained earnings: U.S. Plans Non-U.S. Plans (In thousands) 2022 2021 2022 2021 Net actuarial loss $ ( 214,607 ) $ ( 250,317 ) $ ( 25,984 ) $ ( 30,045 ) Prior service (costs) credits ( 7 ) ( 12 ) 518 1,023 Total recognized in accumulated other comprehensive $ ( 214,614 ) $ ( 250,329 ) $ ( 25,466 ) $ ( 29,022 ) The following table includes the changes recognized in other comprehensive income: U.S. Plans Non-U.S. Plans (In thousands) 2022 2021 2022 2021 Changes in plan assets and benefit obligations recognized in other Prior service cost $ - $ - $ 294 $ - Net (gain) arising during the year ( 18,794 ) ( 60,857 ) ( 1,517 ) ( 21,838 ) Effect of exchange rates on amounts included in AOCI - - ( 1,999 ) 6,465 Amounts recognized as a component of net periodic benefit cost: Amortization or curtailment recognition of prior service (cost) benefit ( 5 ) ( 8 ) 139 150 Amortization or settlement recognition of net (loss) ( 16,916 ) ( 30,005 ) ( 473 ) ( 2,748 ) Total recognized in other comprehensive (income) $ ( 35,715 ) $ ( 90,870 ) $ ( 3,556 ) $ ( 17,971 ) In measuring the projected benefit obligation and net periodic pension cost for our plans, we utilize actuarial valuations. These valuations include specific information pertaining to individual plan participants, such as salary, age and years of service, along with certain assumptions. The most significant assumptions applied include discount rates, expected return on plan assets and rate of compensation increases. We evaluate these assumptions, at a minimum, on an annual basis, and make required changes, as applicable. In developing our expected long-term rate of return on pension plan assets, we consider the current and expected target asset allocations of the pension portfolio, as well as historical returns and future expectations for returns on various categories of plan assets. Expected return on assets is determined by using the weighted-average return on asset classes based on expected return for the target asset allocations of the principal asset categories held by each plan. In determining expected return, we consider both historical performance and an estimate of future long-term rates of return. Actual experience is used to develop the assumption for compensation increases. The following weighted-average assumptions were used to determine our year-end benefit obligations and net periodic pension cost under the plans: U.S. Plans Non-U.S. Plans Year-End Benefit Obligations 2022 2021 2022 2021 Discount rate 4.43 % 2.75 % 4.02 % 2.72 % Rate of compensation increase 3.21 % 3.19 % 2.94 % 2.91 % U.S. Plans Non-U.S. Plans Net Periodic Pension Cost 2022 2021 2020 2022 2021 2020 Discount rate 2.76 % 2.78 % 3.65 % 2.72 % 2.49 % 2.61 % Expected return on plan assets 6.50 % 7.00 % 7.40 % 3.46 % 3.30 % 3.91 % Rate of compensation increase 3.19 % 3.19 % 3.80 % 2.91 % 2.86 % 2.86 % The following tables illustrate the weighted-average actual and target allocation of plan assets: U.S. Plans Target Allocation Actual Asset Allocation (Dollars in millions) as of May 31, 2022 2022 2021 Equity securities 55 % $ 326.2 $ 387.1 Fixed income securities 20 % 117.0 112.0 Multi-class 20 % 136.6 150.8 Cash 5 % 37.0 22.3 Other 0.2 0.2 Total assets 100 % $ 617.0 $ 672.4 Non-U.S. Plans Target Allocation Actual Asset Allocation (Dollars in millions) as of May 31, 2022 2022 2021 Equity securities 37 % $ 69.2 $ 103.4 Fixed income securities 52 % 101.1 108.2 Cash 0.1 0.1 Property and other 11 % 23.0 28.2 Total assets 100 % $ 193.4 $ 239.9 The following tables present our pension plan assets as categorized using the fair value hierarchy at May 31, 2022 and 2021: U.S. Plans (In thousands) Quoted Prices Significant Significant Fair Value at U.S. Treasury and other government $ - $ 34,902 $ - $ 34,902 State and municipal bonds - 576 - 576 Foreign bonds - 1,150 - 1,150 Mortgage-backed securities - 10,254 - 10,254 Corporate bonds - 23,883 - 23,883 Stocks - large cap 30,295 - - 30,295 Mutual funds - equity - 295,905 - 295,905 Mutual funds - multi-class - 136,583 - 136,583 Mutual funds - fixed - 16,368 - 16,368 Cash and cash equivalents 37,004 - - 37,004 Limited partnerships - - 166 166 Investments measured at NAV (1) 29,874 Total $ 67,299 $ 519,621 $ 166 $ 616,960 (1) In accordance with Subtopic 820-10, Fair Value Measurements and Disclosures, certain investments that are measured at fair value using the net asset value ("NAV") per share practical expedient have not been classified in the fair value hierarchy.

The primary objective for the investments of the Retirement Plan is to provide for long-term growth of capital without undue exposure to risk. This objective is accomplished by utilizing a strategy of equities, fixed-income securities and cash equivalents in a mix that is conducive to participation in a rising market, while allowing for adequate protection in a falling market. Our Investment Committee oversees the investment allocation process, which includes the selection and evaluation of investment managers, the determination of investment objectives and risk guidelines, and the monitoring of actual investment performance. In order to manage investment risk properly, Plan policy prohibits short selling, securities lending, financial futures, options and other specialized investments, except for certain alternative investments specifically approved by the Investment Committee. The Investment Committee reviews, on a quarterly basis, reports of actual Plan investment performance provided by independent third parties, in addition to its review of the Plan investment policy on an annual basis. The investment objectives are similar for our plans outside of the United States, subject to local regulations. The goals of the investment strategy for pension assets include: the total return of the funds shall, over an extended period of time, surpass an index composed of the MSCI World Stock Index (equity), the Barclays Long-Term Government/Credit Index (fixed income), and 30-day Treasury Bills (cash), weighted appropriately to match the asset allocation of the plans. The equity portion of the funds shall surpass the MSCI World Stock Index over a full market cycle, while the fixed-income portion shall surpass Barclays Long-Term Government/Credit Index over a full market cycle. The purpose of the fixed-income fund is to reduce the overall volatility of the plan liabilities and provide a hedge against interest rate fluctuations. Therefore, the primary objective of the fixed-income portion is to match the Barclays Long-Term Government/Credit Index. We expect to pay the following estimated pension benefit payments in the next five years (in millions): $ 65.5 in 2023, $ 68.8 in 2024, $ 70.9 in 2025, $ 73.9 in 2026 and $ 76.3 in 2027. In the five years thereafter (2028-2032), we expect to pay $ 379.8 million. In addition to the defined benefit pension plans discussed above, we also sponsor associate savings plans under Section 401(k) of the Internal Revenue Code, which cover most of our associates in the United States. We record expense for defined contribution plans for any employer-matching contributions made in conjunction with services rendered by associates. The majority of our plans provide for matching contributions made in conjunction with services rendered by associates. Matching contributions are invested in the same manner that the participants invest their own contributions. Matching contributions charged to income wer e $ 24.7 million, $ 21.7 million and $ 21.1 million for the years ending May 31, 2022, 2021 and 2020, respectively.

Contingencies and Accrued Losses	May 31, 2022
Commitments and Contingencies Disclosure [Abstract]
Contingencies and Accrued Losses	NOTE Q — CONTINGENCIES AND ACCRUED LOSSES Accrued loss reserves consist of the following: May 31, 2022 2021 (In thousands) Accrued product liability and other loss reserves $ 16,003 $ 18,296 Accrued warranty reserves 7,450 9,429 Accrued environmental reserves 1,055 1,329 Total Accrued Loss Reserves - Current $ 24,508 $ 29,054 Accrued product liability and other loss reserves - noncurrent $ 26,226 $ 26,614 Accrued warranty liability - noncurrent 3,455 3,746 Accrued environmental reserves - noncurrent 6,254 6,267 Total Accrued Loss Reserves - Noncurrent $ 35,935 $ 36,627 Product Liability Matters We provide, through our wholly owned insurance subsidiaries, certain insurance coverage, primarily product liability coverage, to our other subsidiaries. Excess coverage is provided by third-party insurers. Our product liability accruals provide for these potential losses, as well as other uninsured claims. Product liability accruals are established based upon actuarial calculations of potential liability using industry experience, actual historical experience and actuarial assumptions developed for similar types of product liability claims, including development factors and lag times. To the extent there is a reasonable possibility that potential losses could exceed the amounts already accrued, we believe that the amount of any such additional loss would be immaterial to our results of operations, liquidity and consolidated financial position. Warranty Matters We also offer warranties on many of our products, as well as long-term warranty programs at certain of our businesses, and have established product warranty liabilities. We review these liabilities for adequacy on a quarterly basis and adjust them as necessary. The primary factors that could affect these liabilities may include changes in performance rates, as well as costs of replacement. Provision for estimated warranty costs is recorded at the time of sale and periodically adjusted, as required, to reflect actual experience. It is probable that we will incur future losses related to warranty claims we have received but that have not been fully investigated and related to claims not yet received. While our warranty liabilities represent our best estimates at May 31, 2022, we can provide no assurances that we will not experience material claims in the future or that we will not incur significant costs to resolve such claims beyond the amounts accrued or beyond what we may recover from our suppliers. Based upon the nature of the expense, product warranty expense is recorded as a component of cost of sales or within SG&A. Also, due to the nature of our businesses, the amount of claims paid can fluctuate from one period to the next. While our warranty liabilities represent our best estimates of our expected losses at any given time, from time to time we may revise our estimates based on our experience relating to factors such as weather conditions, specific circumstances surrounding product installations and other factors. The following table includes the changes in our accrued warranty balances: Year Ended May 31, 2022 2021 2020 (In thousands) Beginning Balance $ 13,175 $ 11,106 $ 10,414 Deductions (1) ( 26,332 ) ( 25,817 ) ( 20,762 ) Provision charged to expense 24,062 27,886 21,454 Ending Balance $ 10,905 $ 13,175 $ 11,106 (1) Primarily claims paid during the year. Environmental Matters Like other companies participating in similar lines of business, some of our subsidiaries are involved in environmental remediation matters. It is our policy to accrue remediation costs when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when we have committed to an appropriate plan of action. We also take into consideration the estimated period of time over which payments may be required. The liabilities are reviewed periodically and, as investigation and remediation activities continue, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not offset by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal superfund sites or similar state-managed sites, third party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites. Other Contingencies One of our subsidiaries has been the subject of a proceeding in which one of its former distributors brought suit against our subsidiary for breach of contract. Following a June 2017 trial, a jury determined that the distributor was not entitled to any damages on the distributor's claims against our subsidiary. On appeal, the Ninth Circuit Court of Appeals ordered a new trial with respect to certain issues. On December 10, 2021, a new jury awarded $ 6.0 million in damages to the distributor. Per the parties' contracts, the distributor may also be entitled to recover some portion of its attorneys' fees from our subsidiary. The distributor timely filed an appeal of the new jury’s verdict, and our subsidiary timely filed a cross-appeal. The appeal action remains pending before the Ninth Circuit Court of Appeals. As a result of the new jury’s award and in consideration of our subsidiary’s appeal, including available contractual arguments limiting the distributor’s recoverable damages, we have accrued $ 2.6 million for this matter at May 31, 2022, which we believe to be the low end of the range of loss. While an ultimate loss in excess of the accrued amount is reasonably possible, we believe that the high end of the range of loss would not be materially more than the $ 6.0 million noted above.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	NOTE R — REVENUE We operate a portfolio of businesses that manufacture and sell a variety of product lines that include specialty paints, protective coatings, roofing systems, sealants and adhesives, among other things. We disaggregate revenues from the sales of our products and services based upon geographical location by each of our reportable segments, which are aligned by similar economic factors, trends and customers, which best depict the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. See Note S, “Segment Information,” to the Consolidated Financial Statements for further details regarding our disaggregated revenues, as well as a description of each of the unique revenue streams related to each of our four reportable segments. Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. The majority of our revenue is recognized at a point in time. However, we also record revenues generated under construction contracts, mainly in connection with the installation of specialized roofing and flooring systems and related services. For certain polymer flooring installation projects, we account for our revenue using the output method, as we consider square footage of completed flooring to be the best measure of progress toward the complete satisfaction of the performance obligation. In contrast, for certain of our roofing installation projects, we account for our revenue using the input method, as that method was the best measure of performance as it considers costs incurred in relation to total expected project costs, which essentially represents the transfer of control for roofing systems to the customer. In general, for our construction contracts, we record contract revenues and related costs as our contracts progress on an over-time model. We have elected to apply the practical expedient to recognize revenue net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. Payment terms and conditions vary by contract type, although our customers’ payment terms generally include a requirement to pay within 30 to 60 days of fulfilling our performance obligations. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined that our contracts generally do not include a significant financing component. We have elected to apply the practical expedient to treat all shipping and handling costs as fulfillment costs, as a significant portion of these costs are incurred prior to control transfer. Significant Judgments Our contracts with customers may include promises to transfer multiple products and/or services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. For example, judgment is required to determine whether products sold in connection with the sale of installation services are considered distinct and accounted for separately, or not distinct and accounted for together with installation services and recognized over time. We provide customer rebate programs and incentive offerings, including special pricing and co-operative advertising arrangements, promotions and other volume-based incentives. These customer programs and incentives are considered variable consideration and recognized as a reduction of net sales. Up-front consideration provided to customers is capitalized as a component of other assets and amortized over the estimated life of the contractual arrangement. We include in revenue variable consideration only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the variable consideration is resolved. In general, this determination is made based upon known customer program and incentive offerings at the time of sale, and expected sales volume forecasts as it relates to our volume-based incentives. This determination is updated each reporting period. Certain of our contracts include contingent consideration that is receivable only upon the final inspection and acceptance of a project. We include estimates of such variable consideration in our transaction price. Based on historical experience, we consider the probability-based expected value method appropriate to estimate the amount of such variable consideration. Our products are generally sold with a right of return and we may provide other credits or incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. Returns and credits are estimated at contract inception and updated at the end of each reporting period as additional information becomes available. We record a right of return liability to accrue for expected customer returns. Historical actual returns are used to estimate future returns as a percentage of current sales. Obligations for returns and refunds were not material individually or in the aggregate. We offer assurance type warranties on our products as well as separately sold warranty contracts. Revenue related to warranty contracts that are sold separately is recognized over the life of the warranty term. Warranty liabilities for our assurance type warranties are discussed further in Note Q, “Contingencies and Accrued Losses,” to the Consolidated Financial Statements. Contract Balances Timing of revenue recognition may differ from the timing of invoicing customers. Our contract assets are recorded for products and services that have been provided to our customer but have not yet been billed, and are included in prepaid expenses and other current assets in our consolidated balance sheets. Our short-term contract liabilities consist of advance payments, or deferred revenue, and are included in other accrued liabilities in our consolidated balance sheets. Trade accounts receivable, net of allowances, and net contract assets consisted of the following: Year Ended May 31, 2022 2021 $ Change % Change (In thousands, except percents) Trade accounts receivable, less allowances $ 1,432,632 $ 1,280,806 $ 151,826 11.9 % Contract assets $ 57,234 $ 33,217 $ 24,017 72.3 % Contract liabilities - short-term ( 44,938 ) ( 33,112 ) ( 11,826 ) 35.7 % Net Contract Assets $ 12,296 $ 105 $ 12,191 11610.5 % The $ 12.2 million increase in our net contract assets from May 31, 2021 to May 31, 2022, resulted primarily due to the timing and volume of construction jobs in progress at May 31, 2022 versus May 31, 2021. We also record long-term deferred revenue, which amounted to $ 62.5 million and $ 67.8 million as of May 31, 2022 and 2021, respectively. The long-term portion of deferred revenue is related to warranty contracts and is included in other long-term liabilities in our consolidated balance sheets. We have elected to adopt the practical expedient to not disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied as of the end of the reporting period for performance obligations that are part of a contract with an original expected duration of one year or less. We recognize an asset for the incremental costs of obtaining a contract with a customer if we expect the benefit of those costs to be longer than one year. As our contract terms are primarily one year or less in duration, we have elected to apply a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. These costs include our internal sales force compensation program and certain incentive programs as we have determined annual compensation is commensurate with annual sales activities. Allowance for Credit Losses Our primary allowance for credit losses is the allowance for doubtful accounts. The allowance for doubtful accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The allowance was based on assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowances for doubtful collection of accounts are included in selling, general and administrative expenses. The following tables summarize the activity for the allowance for credit losses for the fiscal year ended May 31, 2022: (In thousands) Balance at June 1, 2021 $ 55,922 Bad debt provision 4,326 Uncollectible accounts written off, net of recoveries ( 10,797 ) Translation adjustments ( 2,782 ) Balance at May 31, 2022 $ 46,669

Segment Information

Segment Information	May 31, 2022
Segment Reporting [Abstract]
Segment Information	NOTE S — SEGMENT INFORMATION We operate a portfolio of businesses and product lines that manufacture and sell a variety of specialty paints, protective coatings, roofing systems, flooring solutions, sealants, cleaners and adhesives. We manage our portfolio by organizing our businesses and product lines into four reportable segments as outlined below, which also represent our operating segments. Within each operating segment, we manage product lines and businesses which generally address common markets, share similar economic characteristics, utilize similar technologies and can share manufacturing or distribution capabilities. Our four operating segments represent components of our business for which separate financial information is available that is utilized on a regular basis by our chief operating decision maker in determining how to allocate the assets of the company and evaluate performance. These four operating segments are each managed by an operating segment manager, who is responsible for the day-to-day operating decisions and performance evaluation of the operating segment’s underlying businesses. We evaluate the profit performance of our segments primarily based on income before income taxes, but also look to EBIT, as a performance evaluation measure because interest (income) expense, net is essentially related to corporate functions, as opposed to segment operations. Our CPG reportable segment products are sold throughout North America and also account for the majority of our international sales. Our construction product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. Products and services within this reportable segment include construction sealants and adhesives, coatings and chemicals, roofing systems, concrete admixture and repair products, building envelope solutions, insulated cladding, flooring systems, and weatherproofing solutions. Our PCG reportable segment products are sold throughout North America, as well as internationally, and are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. Products and services within this reportable segment include high-performance flooring solutions, corrosion control and fireproofing coatings, infrastructure repair systems, fiberglass reinforced plastic gratings and drainage systems. Our Consumer reportable segment manufactures and markets professional use and do-it-yourself (“DIY”) products for a variety of mainly consumer applications, including home improvement and personal leisure activities. Our Consumer reportable segment’s major manufacturing and distribution operations are located primarily in North America, along with a few locations in Europe and other parts of the world. Our Consumer reportable segment products are primarily sold directly to mass merchandisers, home improvement centers, hardware stores, paint stores, craft shops and through distributors. The Consumer reportable segment offers products that include specialty, hobby and professional paints; caulks; adhesives; cleaners; sandpaper and other abrasives; silicone sealants and wood stains. Sales to The Home Depot, Inc. represented less than 10 % of our consolidated net sales for fiscal 2022, 2021 and 2020, respectively. Furthermore, sales to The Home Depot, Inc. represented 25 %, 26 % and 26 % of our Consumer segment net sales for each of the fiscal years ended May 31, 2022, 2021 and 2020, respectively. Our SPG reportable segment products are sold throughout North America and a few international locations, primarily in Europe. Our SPG product lines are sold directly to contractors, distributors and end-users, such as industrial manufacturing facilities, public institutions and other commercial customers. The SPG reportable segment offers products that include industrial cleaners, restoration services equipment, colorants, nail enamels, exterior finishes, edible coatings and specialty glazes for pharmaceutical and food industries, and other specialty original equipment manufacturer (“OEM”) coatings. In addition to our four reportable segments, there is a category of certain business activities and expenses, referred to as corporate/other, that does not constitute an operating segment. This category includes our corporate headquarters and related administrative expenses, results of our captive insurance companies, gains or losses on the sales of certain assets and other expenses not directly associated with any reportable segment. Assets related to the corporate/other category consist primarily of investments, prepaid expenses and headquarters’ property and equipment. These corporate and other assets and expenses reconcile reportable segment data to total consolidated income before income taxes and identifiable assets. We reflect income from our joint ventures on the equity method, and receive royalties from our licensees. The following tables present a disaggregation of revenues by geography, and the results of our reportable segments consistent with our management philosophy, by representing the information we utilize, in conjunction with various strategic, operational and other financial performance criteria, in evaluating the performance of our portfolio of businesses.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	May 31, 2022
Accounting Policies [Abstract]
Consolidation, Noncontrolling Interests and Basis of Presentation	1) Consolidation, Noncontrolling Interests and Basis of Presentation Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, our Consolidated Financial Statements include 100 % of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three-month periods ending August 31, November 30 and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).
Use of Estimates	2) Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Acquisitions/Divestitures	3) Acquisitions/Divestitures We account for business combinations and asset acquisitions using the acquisition method of accounting and, accordingly, the assets and liabilities of the acquired entities are recorded at their estimated fair values at the acquisition date. During the fiscal year ended May 31, 2022, we completed a total of eight acquisitions in three of our four reportable segments. Most notably, within our CPG reportable segment, we acquired a chemical manufacturing facility located in Corsicana, Texas. The facility will be repurposed to act as a manufacturing campus for a number of RPM's operating companies. Also within our CPG reportable segment, we acquired a provider of indoor air quality solutions headquartered in Clearwater, Florida. We also completed several other acquisitions within our CPG, SPG and PCG reportable segments. During the fiscal year ended May 31, 2021, we completed a total of four acquisitions in each of our four reportable segments. Within our Consumer reportable segment, we acquired a manufacturer of sandpaper and other abrasives headquartered in Fairborn, Ohio. Within our PCG reportable segment, we acquired a manufacturer of raised flooring systems headquartered in Denver, Colorado. We also completed other acquisitions within our SPG and CPG reportable segments. The purchase price for each acquisition has been allocated to the estimated fair values of the assets acquired and liabilities assumed as of the date of acquisition. We have finalized the purchase price allocation for our fiscal 2021 acquisitions. For acquisitions completed during fiscal 2022, the valuations of consideration transferred, total assets acquired and liabilities assumed are substantially complete. The primary areas that remain open relate to working capital adjustments and other intangible asset valuations. Acquisitions are aggregated by year of purchase in the following table : Fiscal 2022 Acquisitions Fiscal 2021 Acquisitions (In thousands) Weighted-Average Total Weighted-Average Total Current assets $ 9,604 $ 50,310 Property, plant and equipment 71,658 27,012 Goodwill N/A 30,747 N/A 41,654 Trade names - indefinite lives N/A 1,050 N/A 16,694 Other intangible assets 13 21,010 20 53,894 Other long-term assets 2,316 6,831 Total Assets Acquired $ 136,385 $ 196,395 Liabilities assumed ( 7,159 ) ( 24,232 ) Net Assets Acquired $ 129,226 (1) $ 172,163 (2) (1) Figure includes cash acquired of $ 1.8 million. (2) Figure includes cash acquired of $ 6.4 million. Our Consolidated Financial Statements reflect the results of operations of acquired businesses as of their respective dates of acquisition. Pro-forma results of operations for the years ended May 31, 2022 and 2021 were not materially different from reported results and, consequently, are not presented.
Foreign Currency	4) Foreign Currency The functional currency for each of our foreign subsidiaries is its principal operating currency. Accordingly, for the periods presented, assets and liabilities have been translated using exchange rates at year end, while income and expense for the periods have been translated using a weighted-average exchange rate. The resulting translation adjustments have been recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity, and will be included in net earnings only upon the sale or liquidation of the underlying foreign investment, neither of which is contemplated at this time. Transaction losses increased during the current fiscal year due to the strengthening of the U.S. dollar, resulting in net transactional losses of approximately $ 4.3 million. This compared to more moderate net transactional foreign exchange losses in fiscal 2021 of approximately $ 2.8 million, and net transactional foreign exchange gains for fiscal 2020 of approximately $ 0.3 million as a result of more modest fluctuations in the strength of the U.S. dollar.
Cash and Cash Equivalents	5) Cash and Cash Equivalents We consider all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. We do not believe we are exposed to any significant credit risk on cash and cash equivalents. The carrying amounts of cash and cash equivalents approximate fair value.
Property, Plant & Equipment	6) Property, Plant & Equipment May 31, 2022 2021 (In thousands) Land $ 88,137 $ 93,455 Buildings and leasehold improvements 519,391 518,205 Machinery and equipment 1,525,387 1,355,822 Total property, plant and equipment, at cost 2,132,915 1,967,482 Less: allowance for depreciation and amortization 1,028,932 1,002,300 Property, plant and equipment, net $ 1,103,983 $ 965,182 We review long-lived assets for impairment when circumstances indicate that the carrying values of these assets may not be recoverable. For assets that are to be held and used, an impairment charge is recognized when the estimated undiscounted future cash flows associated with the asset or group of assets are less than their carrying value. If impairment exists, an adjustment is made to write the asset down to its fair value, and a loss is recorded for the difference between the carrying value and the fair value. Fair values are determined based on quoted market values, discounted cash flows, internal appraisals or external appraisals, as applicable. Assets to be disposed of are carried at the lower of their carrying value or estimated net realizable value. Depreciation is computed primarily using the straight-line method over the following ranges of useful lives: Buildings and leasehold improvements 1 to 50 years Machinery and equipment 1 to 36 years Total deprecia tion expense for each fiscal period includes the charges to income that result from the amortization of assets recorded under finance leases. For the periods ended May 31, 2022, 2021 and 2020, we recorded depreciation expense of $ 104.3 million, $ 99.4 million, and $ 108.5 million , respectively.
Revenue Recognition	7) Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. The majority of our revenue is recognized at a point in time. However, we also record revenues generated under construction contracts, mainly in connection with the installation of specialized roofing and flooring systems and related services. For certain polymer flooring installation projects, we account for our revenue using the output method, as we consider square footage of completed flooring to be the best measure of progress toward the complete satisfaction of the performance obligation. In contrast, for certain of our roofing installation projects, we account for our revenue using the input method, as that method was the best measure of performance as it considers costs incurred in relation to total expected project costs, which essentially represents the transfer of control for roofing systems to the customer. In general, for our construction contracts, we record contract revenues and related costs as our contracts progress on an over-time model.
Shipping Costs	8) Shipping Costs We identify shipping and handling costs as costs paid to third-party shippers for transporting products to customers, and we include these costs in cost of sales in our Consolidated Statements of Income.
Allowance for Credit Losses	9) Allowance for Credit Losses Our primary allowance for credit losses is the allowance for doubtful accounts. The allowance for doubtful accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The allowance is established using assessments of current creditworthiness of customers, historical collection experience, the aging of receivables and other currently available evidence. Trade accounts receivable balances are written-off against the allowance if a final determination of uncollectibility is made. All provisions for allowances for doubtful collection of accounts are included in selling, general and administrative expenses. Actual collections of trade receivables could differ from our estimates due to changes in future economic or industry conditions or specific customer’s financial conditions. For the periods ended May 31, 2022, 2021 and 2020, bad debt expense approximated $ 4.3 million, $ 10.0 million and $ 16.7 million, respectively. Bad debt expense was elevated in fiscal 2021 and 2020 due in part to additional write-offs associated with exiting unprofitable product lines and regions in conjunction with our MAP to Growth. Fiscal 2020 bad debt expense also re flects, although to a much lesser degree, the impact the Covid pandemic had on some of our customers’ ability to pay timely.
Inventories	10) Inventories Inventories are stated at the lower of cost or net realizable value, cost being determined on a first-in, first-out (FIFO) basis and net realizable value being determined on the basis of replacement cost. Inventory costs include raw materials, labor and manufacturing overhead. We review the net realizable value of our inventory in detail on an on-going basis, with consideration given to various factors, which include our estimated reserves for excess, obsolete, slow-moving or distressed inventories. If actual market conditions differ from our projections, and our estimates prove to be inaccurate, write-downs of inventory values and adjustments to cost of sales may be required. Historically, our inventory reserves have approximated actual experience. For the periods ended May 31, 2022, 2021 and 2020, charges related to slow moving and/or obsolete inventory on hand approximated $ 9.8 million, $ 3.7 million and $ 39.6 million, respectively. Charges recorded during fiscal 2022 and fiscal 2021 were more normalized in comparison to fiscal 2020, which had elevated inventory charges associated with our MAP to Growth restructuring activities. During fiscal 2020, we recorded $ 28.8 million within our Consumer reportable segment consisting of proactive management of excess quantities of inventory in order to accelerate cash conversion, SKU rationalization, and exiting unprofitable product lines and regions and $ 3.2 million within our PCG segmen t related to exiting unprofitable product lines and regions. Inventories were composed of the following major classes: May 31, 2022 2021 (In thousands) Raw materials and supplies $ 560,886 $ 447,220 Finished goods 651,732 490,875 Total Inventory $ 1,212,618 $ 938,095
Goodwill and Other Intangible Assets	11) Goodwill and Other Intangible Assets We account for goodwill and other intangible assets in accordance with the provisions of Accounting Standards Codification ("ASC") 350 and account for business combinations using the acquisition method of accounting and, accordingly, the assets and liabilities of the entities acquired are recorded at their estimated fair values at the acquisition date. Goodwill Goodwill represents the excess of the purchase price paid over the fair value of net assets acquired, including the amount assigned to identifiable intangible assets. Goodwill is assigned to reporting units that are expected to benefit from the synergies of the business combination as of the acquisition date. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill. We evaluate our reporting units when changes in our operating structure occur, and if necessary, reassign goodwill using a relative fair value allocation approach. We test our goodwill balances at least annually, or more frequently as impairment indicators arise, at the reporting unit level. Our annual impairment assessment date has been designated as the first day of our fourth fiscal quarter. Our reporting units have been identified at the component level, which is one level below our operating segments. We follow the Financial Accounting Standards Board (“FASB”) guidance found in ASC 350 that simplifies how an entity tests goodwill for impairment. It provides an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, and whether it is necessary to perform a quantitative goodwill impairment test. We assess qualitative factors in each of our reporting units that carry goodwill. We assess these qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. The quantitative process is required only if we conclude that it is more likely than not that a reporting unit’s fair value is less than its carrying amount. However, we have an unconditional option to bypass a qualitative assessment and proceed directly to performing the quantitative analysis. We applied the quantitative process during our annual goodwill impairment assessments performed during the fourth quarters of fiscal 2022, 2021 and 2020. In applying the quantitative test, we compare the fair value of a reporting unit to its carrying value. If the calculated fair value is less than the current carrying value, then impairment of the reporting unit exists. Calculating the fair value of a reporting unit requires our use of estimates and assumptions. We use significant judgment in determining the most appropriate method to establish the fair value of a reporting unit. We estimate the fair value of a reporting unit by employing various valuation techniques, depending on the availability and reliability of comparable market value indicators, and employ methods and assumptions that include the application of third-party market value indicators and the computation of discounted future cash flows determined from estimated cashflow adjustments to a reporting unit’s annual projected earnings before interest, taxes, depreciation and amortization (“EBITDA”), or adjusted EBITDA, which adjusts for one-off items impacting revenues and/or expenses that are not considered by management to be indicative of ongoing operations. Our fair value estimations may include a combination of value indications from both the market and income approaches, as the income approach considers the future cash flows from a reporting unit’s ongoing operations as a going concern, while the market approach considers the current financial environment in establishing fair value. In applying the market approach, we use market multiples derived from a set of similar companies. In applying the income approach, we evaluate discounted future cash flows determined from estimated cashflow adjustments to a reporting unit’s projected EBITDA. Under this approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows. In applying the discounted cash flow methodology utilized in the income approach, we rely on a number of factors, including future business plans, actual and forecasted operating results, and market data. The significant assumptions employed under this method include discount rates; revenue growth rates, including assumed terminal growth rates; and operating margins used to project future cash flows for a reporting unit. The discount rates utilized reflect market-based estimates of capital costs and discount rates adjusted for management’s assessment of a market participant’s view with respect to other risks associated with the projected cash flows of the individual reporting unit. Our estimates are based upon assumptions we believe to be reasonable, but which by nature are uncertain and unpredictable. We believe we incorporate ample sensitivity ranges into our analysis of goodwill impairment testing for a reporting unit, such that actual experience would need to be materially out of the range of expected assumptions in order for an impairment to remain undetected. Changes in the Composition of Reporting Units in Fiscal 2020 On June 1, 2019, the composition of our reportable segments was revised. Prior to implementing the revised segment reporting structure beginning in fiscal 2020, our previously disclosed Industrial segment comprised two operating segments, the CPG operating segment and the PCG operating segment. Each of these operating segments comprised several reporting units, all of which were tested during the annual goodwill impairment tests during the fourth quarter of fiscal 2020, 2021 and 2022. Also, in connection with our Map to Growth, we realigned certain businesses and management structure within our SPG segment. As such, our former Wood Finishes Group reporting unit was split into two separate reporting units: Guardian and Wood Finishes Group. Additionally, our former Kop-Coat Group reporting unit was split into two reporting units: Kop-Coat Industrial Protection Products and Kop-Coat Group. We performed an interim goodwill impairment test for each of the new reporting units upon the change in business realignment using a quantitative assessment. We concluded that the estimated fair values exceeded the carrying values for these new reporting units, and accordingly, no indications of impairment were identified as a result of these changes during the first quarter of fiscal 2020. Conclusion on Annual Goodwill Impairment Tests As a result of the annual impairment assessments performed for fiscal 2022, 2021 and 2020, there were no goodwill impairments. Indefinite-Lived Intangible Assets Additionally, we test all indefinite-lived intangible assets for impairment at least annually during our fiscal fourth quarter. We follow the guidance provided by ASC 350 that simplifies how an entity tests indefinite-lived intangible assets for impairment. It provides an option to first assess qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount before applying traditional quantitative tests. We applied quantitative processes during our annual indefinite-lived intangible asset impairment assessments performed during the fourth quarters of fiscal 2022, 2021 and 2020. The annual impairment assessment involves estimating the fair value of each indefinite-lived asset and comparing it with its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, we record an impairment loss equal to the difference. Calculating the fair value of the indefinite-lived assets requires our significant use of estimates and assumptions. We estimate the fair values of our intangible assets by applying a relief-from-royalty calculation, which includes discounted future cash flows related to each of our intangible asset’s projected revenues. In applying this methodology, we rely on a number of factors, including actual and forecasted revenues and market data. Our required annual impairment test of each of our indefinite-lived intangible assets performed during fiscal 2022, 2021 and 2020 did not result in an impairment charge. Although no impairment losses were recorded as a result of our annual impairment tests, we did record an intangible impairment charge in fiscal 2020. In fiscal 2020, in connection with Map to Growth, we recorded an impairment charge of $ 4.0 million included in restructuring expense in our Consumer reportable segment for impairment losses on indefinite-lived trade names. Refer to Note C “Goodwill and Other Intangible Assets” for additional details on this indefinite-lived intangible asset impairment charge. Definite-Lived Intangible Assets In accordance with the guidance provided by ASC 360, we assess identifiable, amortizable intangibles assets for impairment whenever events or changes in facts and circumstances indicate the possibility that the carrying values of these assets may not be recoverable over their estimated remaining useful lives. Factors considered important in our assessment, which might trigger an impairment evaluation, include the following: • significant under-performance relative to historical or projected future operating results; • significant changes in the manner of our use of the acquired assets; • significant changes in the strategy for our overall business; and • significant negative industry or economic trends. Measuring a potential impairment of amortizable intangibles assets requires the use of various estimates and assumptions, including the determination of which cash flows are directly related to the assets being evaluated, the respective useful lives over which those cash flows will occur and potential residual values, if any. If we determine that the carrying values of these assets may not be recoverable based upon the existence of one or more of the above-described indicators or other factors, any impairment amounts would be measured based on the projected net cash flows expected from these assets, including any net cash flows related to eventual disposition activities. The determination of any impairment losses would be based on the best information available, including internal estimates of discounted cash flows; market participant assumptions; quoted market prices, when available; and independent appraisals, as appropriate, to determine fair values. Cash flow estimates would be based on our historical experience and our internal business plans, with appropriate discount rates applied. We did not record any impairment charges related to our definite-lived intangible assets during fiscal 2022, 2021 and 2020.
Advertising Costs	12) Advertising Costs Advertising costs are charged to operations w hen incurred and are included in SG&A expenses. For the years ended May 31, 2022, 2021 and 2020, advertising costs were $ 45.4 million, $ 61.1 million and $ 49.7 million, respectively.
Research and Development	13) Research and Development Research and development costs are charged to operations when incurred and are included in SG&A expenses. The amounts charged to expense for the years ended May 31, 2022, 2021 and 2020 were $ 80.5 million, $ 77.6 million and $ 76.5 million, respectively.
Stock-Based Compensation	14) Stock-Based Compensation Stock-based compensation represents the cost related to stock-based awards granted to our associates and directors, which may include restricted stock and stock appreciation rights (“SARs”). We measure stock-based compensation cost at the date of grant, based on the estimated fair value of the award. We recognize the cost as expense on a straight-line basis (net of estimated forfeitures) over the related vesting period. Refer to Note J, “Stock-Based Compensation,” for further information.
Investment Expense (Income), Net	15) Investment Expense (Income), Net Investment expense (income), net, consists of the following components: Year Ended May 31, 2022 2021 2020 (In thousands) Interest (income) $ ( 4,435 ) $ ( 3,555 ) $ ( 5,313 ) Net loss (gain) on marketable securities 17,706 ( 38,774 ) ( 1,629 ) Dividend (income) ( 5,676 ) ( 2,121 ) ( 2,797 ) Investment expense (income), net $ 7,595 $ ( 44,450 ) $ ( 9,739 ) Net Loss (Gain) on Marketable Securities Year Ended May 31, 2022 2021 2020 (In thousands) Unrealized losses (gains) on marketable equity securities $ 19,164 $ ( 16,133 ) $ ( 1,457 ) Realized (gains) on marketable equity securities ( 1,488 ) ( 22,680 ) ( 237 ) Realized losses on available-for-sale debt securities 30 39 65 Net loss (gain) on marketable securities $ 17,706 $ ( 38,774 ) $ ( 1,629 )
Other (Income) Expense, Net	16) Other (Income) Expense, Net Other (income) expense, net, consists of the following components: Year Ended May 31, 2022 2021 2020 (In thousands) Royalty (income) expense, net (a) $ ( 915 ) $ ( 387 ) $ 5,206 (Income) related to unconsolidated equity affiliates ( 350 ) ( 516 ) ( 165 ) Pension non-service (credit) cost ( 10,581 ) 14,542 6,076 Loss on divestiture (b) - - 949 Other (income) expense, net $ ( 11,846 ) $ 13,639 $ 12,066 (a) Includes a $ 5.3 million charge incurred during the fourth quarter of fiscal 2020 related to the termination of a licensing agreement within our Consumer reportable segment. (b) Reflects the loss incurred upon divestiture of a contracting business located in Australia, which had reported through our PCG segment.
Income Taxes	17) Income Taxes The provision for income taxes is calculated using the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for the tax effect of temporary differences between the financial statement carrying amount of assets and liabilities and the amounts used for income tax purposes and for certain changes in valuation allowances. Valuation allowances are recorded to reduce certain deferred tax assets when, in our estimation, it is more likely than not that a tax benefit will not be realized.
Earnings Per Share of Common Stock	18) Earnings Per Share of Common Stock Earnings per share (EPS) is computed using both the treasury stock and two-class method, as our unvested share-based payment awards contain rights to receive non-forfeitable dividends are considered participating securities. We calculate both Basic and Diluted EPS under each method and compare the results, reporting the method that is most dilutive. Basic EPS of common stock is computed by dividing net income by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS of common stock is computed on the basis of the weighted-average number of shares of common stock, plus the effect of dilutive potential shares of common stock outstanding during the period using the treasury stock method. Dilutive potential shares of common stock include outstanding SARS and restricted stock awards. The treasury stock method also assumes that we use the proceeds from the hypothetical exercise of the stock compensation awards to repurchase common stock at the average market price during the period. The two-class method determines EPS for each class of common stock and participating securities according to dividends and dividend equivalents and their respective participation rights in undistributed earnings. See Note L, “Earnings Per Share,” to the Consolidated Financial Statements for additional information.
Recent Accounting Pronouncements	19) Recent Accounting Pronouncements New Pronouncements Adopted In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740),” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption of the amendments was permitted. Depending on the amendment, adoption may have been applied on the retrospective, modified retrospective or prospective basis. The adoption of this new guidance, effective June 1, 2021 using the prospective method, did no t have a material impact on our Consolidated Financial Statements. New Pronouncements Issued We are not aware of any recently issued accounting pronouncements that have not yet been adopted by us and which would have a material impact on our consolidated financial statements.
Subsequent Event	20) Subsequent Event From June 1, 2022 through July 22, 2022, we repurchased 303,079 shares of RPM common stock since May 31, 2022, at a cost of approximately $ 25.0 million, or an average of $ 82.49 per share, under the stock repurchase program described further in Note I, "Stock Repurchase Program."
