Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Nature of Operations: Enerpac Tool Group Corp. (the “Company”), is a global manufacturer of a broad range of industrial products and solutions, organized into two operating segments. The Industrial Tools & Services segment ("IT&S"), the Company's only reportable segment, is primarily engaged in the design, manufacture and distribution of branded hydraulic and mechanical tools and in providing services and tool rental to the infrastructure, industrial maintenance, infrastructure, repair, and operations, oil & gas, mining and alternative and renewable energy and construction markets. Consolidation and Presentation: The consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. The results of companies acquired or disposed of during the year are included in the consolidated financial statements from the effective date of acquisition or until the date of divestiture. All intercompany balances, transactions and profits have been eliminated in consolidation. At August 31, 2019, the Company's former Engineered Components & Systems ("EC&S") segment was considered held for sale and was subsequently divested on October 31, 2019. As the divestiture represented a strategic shift in our operations, the results of the former segment through the date of divestiture and subsequent impacts to the financial results from retained liabilities are recorded in "Loss from discontinued operations, net of income taxes" within the Consolidated Statements of Operations. The results of the Cortland Fibron and Precision Hayes businesses which were a component of the EC&S segment prior to their divestiture in the year ended August 31, 2019, were also part of the strategic shift, as such, they are also reflected in "Loss from discontinued operations, net of income taxes" within the Consolidated Statements of Operations. The Company has updated our historical caption of "Selling, administrative and engineering expenses" in the Consolidated Statements of Operations to "Selling, general and administrative expenses." There has been no change to the composition of expenses within the caption in the current or historical periods presented. Cash Equivalents: The Company considers all highly liquid investments with original maturities of 90 days or less to be cash equivalents. Inventories: Inventories are comprised of material, direct labor and manufacturing overhead. A majority of inventory is recorded on the first-in, first-out or average cost method and is stated at the lower of cost or net realizable value. A portion of U.S. owned inventory is determined using the last-in, first-out (“LIFO”) method (48.4% a nd 44.1% of total inventories as of August 31, 2021 and 2020, respectively). If the LIFO method were not used, inventory balances would be higher than reported amounts in the consolidated balance sheets b y $15.9 million and $10.2 million at August 31, 2021 and 2020, respectively. The nature of the Company’s products is such that they generally have a very short production cycle. Consequently, the amount of work-in-process at any point in time is minimal. In addition, many parts or components are ultimately either sold individually or assembled with other parts making a distinction between raw materials and finished goods impractical to determine. Certain locations maintain and manage their inventories using a job cost system where the distinction of categories of inventory by state of completion is also not available. As a result of these factors, it is neither practical nor cost effective to segregate the amounts of raw materials, work-in-process or finished goods inventories at the respective balance sheet dates, as segregation would only be possible as the result of physical inventories which are taken at dates different from the balance sheet dates. Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated on a straight-line basis over the estimated useful lives of the assets, ranging from ten two ase. Depreciation expense was $13.4 million, $12.4 million and $11.3 million for the years ended August 31, 2021, 2020 and 2019, respectively. The following is a summary of the Company's components of property, plant and equipment (in thousands): August 31, 2021 August 30, 2020 Land, buildings and improvements $ 16,617 $ 33,548 Machinery and equipment 145,541 134,536 Gross property, plant and equipment 162,158 168,084 Less: Accumulated depreciation (113,568) (106,679) Property, plant and equipment, net $ 48,590 $ 61,405 Leases: We determine if an arrangement contains a lease in whole or in part at the inception of the contract and identify classification of the lease as financing or operating. We account for the underlying operating lease asset at the individual lease level. Operating leases are recorded as operating lease right-to-use (“ROU”) assets in “Other long-term assets” and operating lease liabilities in “Other current liabilities” and “Other long-term liabilities” on the Consolidated Balance Sheets. All leases greater than 12 months result in recognition of a ROU asset and a liability at the lease commencement date and are recorded at the present value of the future minimum lease payments over the lease term. The lease term is equal to the initial term at commencement plus any renewal or extension options that the Company is reasonably certain will be exercised. ROU assets at the date of commencement are equal to the amount of the initial lease liability, the initial direct costs incurred by the Company and any prepaid lease payments less any incentives received. Lease expense for operating leases is recognized on a straight-line basis over the lease term or remaining useful life. As most of our leases do not provide the information required to determine the implicit rate, we utilize a consolidated group incremental borrowing rate for all leases as the Company has centralized treasury operations. The incremental borrowing rate is derived through a combination of inputs such as the Company's credit rating, impact of collaborated borrowing capabilities and lease term. Leases with the duration of less than one-year are not recognized on the balance sheet and are expensed on a straight-line basis over the lease term. In addition, we do not separate lease components from non-lease components for all asset classes. Goodwill and Other Intangible Assets: Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are subject to annual impairment testing. Other intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, trademarks and tradenames, are amortized over periods from one to twenty-five years. The Company’s goodwill is tested for impairment annually, during the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company performs impairment reviews for its reporting units using a fair value method based on management’s judgments and assumptions. In estimating the fair value, the Company utilizes a discounted cash flow model, which is dependent on a number of assumptions, most significantly forecasted revenues and operating profit margins, and the weighted average cost of capital. The estimated fair value of the reporting unit is compared to the carrying amount of the reporting unit, including goodwill. If the carrying value of the reporting unit exceeds its fair value, an impairment loss is recorded and should not exceed the total amount of the goodwill allocated to the reporting unit. Indefinite-lived intangible assets are also subject to an annual impairment test. On an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired, the fair value of the indefinite-lived intangible assets are evaluated by the Company to determine if an impairment charge is required. A considerable amount of management judgment is required in performing impairment tests, principally in determining the fair value of each reporting unit and the indefinite-lived intangible assets. Product Warranty Costs : The Company generally offers its customers an assurance warranty on products sold, although warranty periods may vary by product type and application. The reserve for future warranty claims, which is recorded within the "Other current liabilities" line on the Consolidated Balance Sheets, is based on historical claim rates and current warranty cost experience. The following is a rollforward of the changes in product warranty reserves for fiscal years 2021 and 2020 (in thousands): 2021 2020 Beginning balance $ 892 $ 1,145 Provision for warranties 1,580 677 Warranty payments and costs incurred (1,171) (934) Warranty activity for divested businesses — (27) Impact of changes in foreign currency rates (1) 31 Ending balance $ 1,300 $ 892 Revenue from Contracts with Customers: The Company recognizes revenue when it satisfies a performance obligation in a contract by transferring control of a distinct good or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation and revenue is measured based on the consideration that the Company expects to be entitled to in exchange for the goods or services transferred. When contracts include multiple products or services to be delivered to the customer, the consideration for each element is generally allocated on the standalone transaction prices of the separate performance obligations, using the adjusted market assessment approach. Under normal circumstances, the Company invoices the customer once transfer of control has occurred and has a right to payment. The typical payment terms vary based on the customer and the types of goods and services in the contract. The period of time between invoicing and when payment is due is not significant, as our standard payment terms are less than one year. Amounts billed and due from customers are classified as receivables on the balance sheet. Customer sales are recorded net of allowances for returns and discounts, which are recognized as a deduction from sales at the time of sale. The Company commits to one-time or on-going trade discounts and promotions with customers that require the Company to estimate and accrue the ultimate costs of such programs.The Company generally does not require collateral or other security for receivables and provides for an allowance for doubtful accounts based on historical experience and a review of its existing receivables. Accounts receivable are stated net of an allowance for doubtful accounts of $4.2 million and $5.0 million at August 31, 2021 and 2020, respectively. Taxes Collected: T axes collected by the Company from a customer concurrent with revenue-producing activities are excluded from "Net sales" within the Consolidated Statements of Operations. Shipping and Handling Costs: The Company records costs associated with shipping its products after control over a product has transferred to a customer and are accounted for as fulfillment costs. These costs are reported in the Consolidated Statements of Operations in "Cost of products sold." Research and Development Costs: Research and development costs consist primarily of an allocation of overall engineering and development resources and are expensed as incurred. Such costs incurred in the development of new products or significant improvements to existing pr oducts were $7.4 million, $7.3 million and $9.3 million in fiscal 2021, 2020 and 2019, respectively. The Company also incurs significant costs in connection with fulfilling custom orders and developing solutions for unique customer needs which are not included in these research and development expense totals. Other Income/Expense: Other income and expense primarily consists of net foreign currency exchange transaction losses of $1.8 million, $2.6 million and $0.2 million in fiscal 2021, 2020 and 2019, respectively. In addition, as a result of the EC&S divestiture and the transition services agreement entered into with the buyer, the Company recorded $4.9 million of other income from providing the agreed upon services in fiscal 2020 . Financing Costs: Financing costs represent interest expense, financing fees and amortization of debt issuance costs, net of interest income. Interest income was $0.7 million, $0.8 million and $0.7 million for fiscal 2021, 2020 and 2019, respectively. Income Taxes: The provision for income taxes includes federal, state, local and non-U.S. taxes on income. Tax credits, primarily for non-U.S. earnings, are recognized as a reduction of the provision for income taxes in the year in which they are available for U.S. tax purposes. Deferred taxes are provided on temporary differences between assets and liabilities for financial and tax reporting purposes as measured by enacted tax rates expected to apply when temporary differences are settled or realized. Future tax benefits are recognized to the extent that realization of those benefits is considered to be more likely than not. A valuation allowance is established for deferred tax assets for which realization is not more likely than not of being realized. The Company has not provided for any residual U.S. income taxes on unremitted earnings of non-U.S. subsidiaries, as such earnings are intended to be indefinitely reinvested to the extent the remittance does not result in an incremental U.S. tax liability. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense and treats any taxes due on future U.S. inclusions in taxable income under the Global Intangible Low-Taxed Income ("GILTI") provision as a current period tax expense. Foreign Currency Translation: The financial statements of the Company’s foreign operations are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and an appropriate weighted average exchange rate for each applicable period within the Consolidated Statements of Operations. Translation adjustments are reflected in the Consolidated Balance Sheets and Consolidated Statements of Shareholders' Equity caption “Accumulated other comprehensive loss.” Accumulated Other Comprehensive Loss: The following is a summary of the components included within accumulated other comprehensive loss (in thousands): August 31, 2021 2020 Foreign currency translation adjustments $ 69,986 $ 75,896 Pension and other postretirement benefit plans 22,998 24,750 Unrecognized losses on cash flow hedges — 78 Accumulated other comprehensive loss $ 92,984 $ 100,724 Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The Company regularly evaluates the estimates and assumptions related to the allowance for doubtful accounts, inventory valuation, warranty reserves, goodwill, intangible and long-lived asset valuations, employee benefit plan liabilities, over-time revenue recognition, income tax liabilities, deferred tax assets and related valuation allowances, uncertain tax positions, restructuring reserves, and litigation and other loss contingencies. The COVID-19 pandemic has negatively impacted, and is likely to continue to negatively impact to varying extents, the global economy. The Company's operating results and financial position will continue to be subject to the general economic conditions created by the pandemic, and the duration and extent to which the pandemic's effects impact the Company's business will depend on future developments, including the distribution and long-term effectiveness of vaccines globally, the impact of COVID-19 variants, such as the Delta variant, and the impact of therapeutics in minimizing its negative effects on macroeconomic conditions, which still remain uncertain. The Company manages the profitability of its product and service & rental categories on a combined basis given the complexity of the business model. This model includes providing integrated product and service solutions resulting in facilities that generate revenues from both product and service & rental categories, which also have indirect and facility overhead costs included in cost of sales. As such, judgment and estimates are required to disaggregate product and service & rental cost of sales including allocating indirect and facility overhead costs between cost of product sales and the cost of service & rental sales. Changes in these judgments and estimates could materially change the allocation of the indirect and facility overhead costs to the different sales categories and the resulting ratio of cost of sales to net sales by category. Because the sales mix heavily favors the product category, a change in the mix of cost of sales between the sales categories would have a more significant impact on the ratio of cost of sales to net sales for the service & rental category. In addition, due to the recent changes in our business model, which includes the integration of the Enerpac and Hydratight businesses within the IT&S segment, the decision to exit certain non-strategic businesses and product lines, and the restructuring actions taken by the Company, the historical ratios of cost of sales to net sales by category may not be indicative of future ratios of cost of sales to net sales by category. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which adds an impairment model that is based on expected losses rather than incurred losses and is called the Current Expected Credit Losses (“CECL”) model. This impairment model is applicable to loans, debt securities, trade receivables, net investments in leases, off-balance sheet credit exposures, reinsurance receivables as well as any other financial asset with the contractual right to receive cash. Under the new model, an allowance equal to the estimate of lifetime expected credit losses is recognized which will result in more timely loss recognition. The guidance is intended to reduce complexity by decreasing the number of credit impairment models. The Company adopted the guidance on September 1, 2020 using the modified retrospective approach and there was no impact to the financial statements as a result of the adoption. In February 2016, the FASB issued ASU 2016-02, Leases (and subsequently ASU 2018-01 and ASU 2019-01), to increase transparency and comparability among organizations by recognizing all lease transactions on the balance sheet as a lease liability and a right-of-use (“ROU”) asset. The amendments also expanded disclosure requirements for key information about leasing arrangements. On September 1, 2019, the Company adopted the standard using a modified retrospective approach and elected the package of practical expedients allowing us to not reassess whether any expired or existing contracts contain leases, the lease classification for any expired or existing leases, and initial direct costs for leases that commenced prior to September 1, 2019. In addition, we elected not to recognize ROU assets or lease liabilities for leases containing terms of 12 months or less and not separate lease components from non-lease components for all asset classes. The Company updated its standard lease accounting policy to address the new standard, revised the Company’s business processes and controls to align to the updated policy and new standard and completed the implementation of and data input into the Company’s lease accounting software solution. The most significant impact of the standard on the Company was the recognition of a $60.8 million ROU asset and operating lease liability on the Consolidated Balance Sheets at adoption. The standard did not have a significant impact on our Consolidated Statements of Operations or Consolidated Statements of Cash Flows. In addition, as a result of sale leaseback transactions in previous years for which gains were deferred and under the new standard would have been recognized, the Company recorded an increase to retained earnings of $0.2 million in the first quarter of fiscal 2020, which represents the recognition of these previously deferred gains. See Note 10, “Leases” for further discussion of the Company’s operating leases. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for a limited time to ease the potential burden of accounting for reference rate reform on financial reporting. This guidance applies to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates. The guidance is effective beginning on March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01 allowing entities to apply certain aspects of ASC 848 (previously ASU 2020-4) to all derivative instruments that undergo a modification of the interest rate used for discounting, margining or contract price alignment as a result of the reference reform. The guidance is also effective through December 31, 2022. The Company has not utilized any of the optional expedients or exceptions available under this guidance. The Company will continue to assess whether this guidance is applicable throughout the effective period.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets: Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are subject to annual impairment testing. Other intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, trademarks and tradenames, are amortized over periods from one to twenty-five years. The Company’s goodwill is tested for impairment annually, during the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company performs impairment reviews for its reporting units using a fair value method based on management’s judgments and assumptions. In estimating the fair value, the Company utilizes a discounted cash flow model, which is dependent on a number of assumptions, most significantly forecasted revenues and operating profit margins, and the weighted average cost of capital. The estimated fair value of the reporting unit is compared to the carrying amount of the reporting unit, including goodwill. If the carrying value of the reporting unit exceeds its fair value, an impairment loss is recorded and should not exceed the total amount of the goodwill allocated to the reporting unit. Indefinite-lived intangible assets are also subject to an annual impairment test. On an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired, the fair value of the indefinite-lived intangible assets are evaluated by the Company to determine if an impairment charge is required. A considerable amount of management judgment is required in performing impairment tests, principally in determining the fair value of each reporting unit and the indefinite-lived intangible assets.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	Note 2. Revenue from Contracts with Customers Nature of Goods and Services The Company generates its revenue under two principal activities, which are discussed below: Product Sales: Sales of tools, heavy-lifting solutions, and rope solutions are recorded when control is transferred to the customer (i.e., performance obligation has been satisfied). For the majority of the Company’s product sales, revenue is recognized at a point in time when control of the product is transferred to the customer, which generally occurs when the product is shipped from the Company to the customer. For certain other products that are highly customized and have a limited alternative use, and for which the Company has an enforceable right of reimbursement for performance completed to date, revenue is recognized over time. We consider the input measure (efforts-expended or cost-to-cost) or output measure as a fair measure of progress for the recognition of over-time revenue associated with these custom products. For a majority of the Company’s custom products, machine hours and labor hours (efforts-expended measurement) are used as a measure of progress. Service & Rental Sales : Service contracts consist of providing highly trained technicians to perform bolting, technical services, machining and joint-integrity work for our customers. These revenues are recognized over time as our customers simultaneously receive and consume the benefits provided by the Company. We consider the input measure (efforts-expended or cost-to-cost) or output measure as a fair measure of progress for the recognition of over-time revenue associated with service contracts. For a majority of the Company’s service contracts, labor hours (efforts-expended measurement) is used as the measure of progress when it is determined to be a better depiction of the transfer of control to the customer due to the timing and pattern of labor hours incurred. Revenue from rental contracts (less than a year and non-customized products) is generally recognized ratably over the contract term, depicting the customer’s consumption of the benefit related to the rental equipment. Disaggregated Revenue and Performance Obligations The Company disaggregates revenue from contracts with customers by reportable segment and product line and by the timing of when goods and services are transferred. See Note 15, "Business Segment, Geographic and Customer Information" for information regarding our revenue disaggregation by reportable segment and product line. The following table presents information regarding revenues disaggregated by the timing of when goods and services are transferred (in thousands): Year Ended August 31, 2021 2020 Revenues recognized at point in time $ 396,457 $ 361,359 Revenues recognized over time 132,203 131,933 Total $ 528,660 $ 493,292 Contract Balances The Company's contract assets and liabilities are as follows (in thousands): August 31, 2021 2020 Receivables, which are included in accounts receivable, net $ 103,233 $ 84,170 Contract assets, which are included in other current assets 8,551 6,145 Contract liabilities, which are included in other current liabilities 3,410 2,145 Receivables: The Company performs its obligations under a contract with a customer by transferring goods or services in exchange for consideration from the customer. The Company typically invoices its customers as soon as control of an asset is transferred and a receivable for the Company is established. Accounts receivable, net is recorded at face amount of customer receivables less an allowance for doubtful accounts. The Company maintains an allowance for doubtful accounts for expected losses as a result of customers’ inability to make required payments. Management evaluates the aging of customer receivable balances, the financial condition of its customers, historical trends and the time outstanding of specific balances to estimate the amount of receivables that will not be collected in the future and records the appropriate provision. The allowance for doubtful accounts was $4.2 million and $5.0 million at at August 31, 2021 and 2020, respectively. Concentration of credit risk: The Company sells products and services through distributors and agents. In certain jurisdictions, those third parties represent a significant portion of our sales in their respective country which can pose a concentration of credit risk if these larger distributors or agents are not timely in their payments. As of August 31, 2021 the Company was exposed to a concentration of credit risk as a result of the payment delinquency of one of our agents whose accounts receivable represent 10.4% of the Company's outstanding accounts receivable. Contract Assets: Contract assets relate to the Company’s rights to consideration for work completed but not billed as of the reporting date on contracts with customers. The contract assets are transferred to receivables when the rights become unconditional. The Company has contract assets on contracts that are generally long-term and have revenues that are recognized over time. Contract Liabilities: As of August 31, 2021, the Company had certain contracts where there were unsatisfied performance obligations and the Company had received cash consideration from customers before the performance obligations were satisfied . The majority of these contracts relate to long-term customer contracts (project durations of greater than three months) and are recognized over time. The Company estimates that the $3.4 million will be recognized in net sales from satisfying those performance obligations within the next twelve months with an immaterial amount recognized in periods thereafter. Timing of Performance Obligations Satisfied at a Point in Time: The Company evaluates when the customer obtains control of the product based on shipping terms, as control will transfer, depending upon such terms, at different points between the Company's manufacturing facility or warehouse and the customer’s location. The Company considers control to have transferred upon shipment or delivery because (i) the Company has a present right to payment at that time; (ii) the legal title has been transferred to the customer; (iii) the Company has transferred physical possession of the product to the customer; and (iv) the customer has significant risks and rewards of ownership of the product. Variable Consideration: The Company estimates whether it will be subject to variable consideration under the terms of the contract and includes its estimate of variable consideration in the transaction price based on the expected value method when it is deemed probable of being realized based on historical experience and trends. Types of variable consideration may include rebates, incentives and discounts, among others, which are recorded as a reduction to net sales at the time when control of a performance obligation is transferred to the customer. Practical Expedients & Exemptions: The Company elected to expense the incremental cost to obtaining a contract when the amortization period for such contracts would be one year or less. The Company does not disclose the value of unperformed obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Note 3. Restructuring Charges The Company has undertaken or committed to various restructuring initiatives, including workforce reductions, leadership changes, plant consolidations to reduce manufacturing overhead, satellite office closures, the continued movement of production and product sourcing to low-cost alternatives and the centralization and standardization of certain administrative functions. Liabilities for severance are generally to be paid within twelve months, while future lease payments related to facilities vacated as a result of restructuring are to be paid over the underlying remaining lease terms. During fiscal 2019, the Company announced a new restructuring plan focused on (i) the integration of the Enerpac and Hydratight businesses (IT&S segment), (ii) the strategic exit of certain commodity-type services in our North America Services operations (IT&S segment) and (iii) driving efficiencies within the overall corporate structure. In the third quarter of fiscal 2020, the Company announced the expansion and revision of this plan, which further simplifies and flattens the corporate structure through elimination of redundancies between the segment and corporate functions, while enhancing our commercial and marketing processes to become even closer to our customers. Restructuring charges associated with this plan were $2.1 million and $6.6 million for the year ended August 31, 2021 and 2020, respectively. Significant charges associated with this plan are not expected in future periods. The following rollforwards summarize restructuring reserve activity for the IT&S reportable segment and corporate (in thousands): Year Ended August 31, 2021 IT&S Corporate Balance as of August 31, 2020 $ 1,443 $ 267 Restructuring charges 2,096 9 Cash payments (1,791) (250) Impact of changes in foreign currency rates (11) — Balance as of August 31, 2021 $ 1,737 $ 26 Year Ended August 31, 2020 IT&S Corporate Balance as of August 31, 2019 $ 2,912 $ — Restructuring charges 4,520 2,073 Cash payments (5,458) (1,286) Other non-cash uses of reserve (1) (554) (521) Impact of changes in foreign currency rates 23 1 Balance as of August 31, 2020 $ 1,443 $ 267 (1) Majority of non-cash uses of reserve represents accelerated equity vesting with employee severance agreements. Total restructuring charges (inclusive of the Other segment) being reported in "Restructuring charges" were $2.4 million for the year ended August 31, 2021. Restructuring charges for the year ended August 31, 2020 were $8.1 million which included approximately $0.8 million of charges being reported in the Consolidated Statements of Operations in "Cost of products sold," with the balance of the charges reported in "Restructuring charges." Restructuring expenses related to Cortland U.S. (Other Segment) were $0.3 million in the year ended August 31, 2021. The year ended August 31, 2020, included $1.6 million of restructuring charges which included approximately $0.8 million of charges reported in the Consolidated Statements of Operations in "Cost of products sold," with the balance of the charges reported in "Restructuring charges." Restructuring reserves for Cortland U.S. were $0.1 million and $0.4 million for the year ended August 31, 2021 and 2020, respectively.

Acquisitions	Note 4. Acquisitions On January 7, 2020, the Company acquired 100% of the stock of HTL Group ("HTL"), a provider of controlled bolting products, calibration and repair services, and tool rental services. The acquisition of HTL provided the Company with a complete line of bolting products and enhanced our European rental capabilities. The Company acquired all of the assets and assumed certain liabilities of HTL for a final purchase price of $33.3 million. The final purchase price allocation resulted in $11.3 million of goodwill (which is not deductible for tax purposes), $16.1 million of intangible assets, and $6.7 million of property, plant and equipment. The intangible assets were comprised of $3.3 million of indefinite-lived tradenames, $12.1 million of amortizable customer relationships and $0.7 million of amortizable patents. The impact on the remaining balance sheet line items was not material.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Note 5. Discontinued Operations and Other Divestiture Activities Discontinued Operations On October 31, 2019, as part of our overall strategy to become a pure-play industrial tools and services company, the Company completed the sale of the businesses comprising its former EC&S segment to wholly owned subsidiaries of BRWS Parent LLC, a Delaware limited liability company and affiliate of One Rock Capital Partners II, LP, for a sales price of approximately $215.8 million, inclusive of $1.3 million of purchase price from the customary finalization of working capital negotiations. Approximately $3.0 million of the purchase price was to be paid in four equal quarterly installments after closing, of which $0.7 million was received in the year ended August 31, 2021 (this final payment was received greater than one year from the divestiture date and, as such, is reflected in "Cash provided by financing activities - discontinued operations" within the Consolidated Statements of Cash Flows). In connection with the completion of the sale and after consideration of working capital adjustments, the Company recorded, in fiscal 2020, a net loss of $4.7 million comprised of a loss of $23.0 million representing the excess of the net assets (exclusive of deferred tax assets and liabilities associated with subsidiaries of the Company whose stock was sold as part of the transaction) as compared to the purchase price less costs to sell and the recognition in earnings of the cumulative effect of foreign currency exchange gains and losses during the year largely offset by an income tax benefit of $18.3 million associated with the write off of the net deferred tax liability on subsidiaries of the EC&S segment for which the stock was divested. The Company also recognized in conjunction with the completion of the sale an additional $3.3 million of impairment & divestiture costs associated with the accelerated vesting of restricted stock awards associated with employees terminated as part of the transaction and $2.7 million of additional divestiture charges which were necessary to complete the transaction. The Company maintains financial exposure associated with this divestiture due to certain retained liabilities of which said activity is recorded in "loss from discontinued operations, net of income taxes" within the Consolidated Statements of Operations for the periods subsequent to the divestiture. At August 31, 2019, the EC&S segment met the criteria for assets held-for-sale treatment. As a result, the Company recognized impairment & divestiture charges in fiscal 2019 of $264.5 million which consisted of $210.0 million representing the excess net book value of the net assets over the anticipated sales proceeds less costs to sell and $54.5 million representing the recognition in earnings of the cumulative effect of foreign currency exchange losses previously recorded in equity since acquisition. On December 31, 2018, the Company completed the sale of the Precision Hayes International business for $23.6 million cash, net of final transaction costs, working capital adjustments, accelerated vesting of equity compensation, retention bonuses and other adjustments. The Company recorded $9.5 million of impairment & divestiture charges during the fiscal year representing the excess of the net book value of the assets held for sale less the anticipated proceeds, less costs to sell. The Company also completed the sale of the Cortland Fibron business on December 19, 2018 for $12.5 million in cash. The Company recognized $1.7 million of impairment & divestiture charges in fiscal 2019 representing the excess net book value of the net assets less the proceeds from sale, net of transaction costs. As the aforementioned divestitures were a part of our strategic shift to become a pure-play industrial tools and services company, the results of their operations (including the stated impairment & divestiture charges) are recorded as a component of "Loss from discontinued operations, net of income taxes" in the Consolidated Statements of Operations for all periods presented. The following represents the detail of "Loss from discontinued operations, net of income taxes" within the Consolidated Statements of Operations (in thousands): Year Ended August 31, 2021 2020 * 2019 Net sales $ — $ 67,010 $ 459,144 Cost of products sold — 49,749 344,563 Gross profit — 17,261 114,581 Selling, general and administrative expenses 1,456 11,561 68,339 Amortization of intangible assets — — 5,666 Restructuring (benefit) charges — (11) 1,779 Impairment & divestiture charges ** — 28,972 286,175 Operating loss (1,456) (23,261) (247,378) Financing costs, net — 14 124 Other (income) expense, net — (104) 1,922 Loss before income tax expense (benefit) (1,456) (23,171) (249,424) Income tax expense (benefit) 679 (18,337) 7,788 Net loss from discontinued operations $ (2,135) $ (4,834) $ (257,212) * "Loss from discontinued operations, net of income taxes" for the year ended August 31, 2020 presented in the table above includes the results of the EC&S segment for the two months ended October 31, 2019 (the divestiture date) as well as the ancillary impacts from certain retained liabilities subsequent to the divestiture. As a result of the classification of the segment as assets and liabilities held for sale for the two months ended October 31, 2019, the Company did not record amortization or depreciation expense in the results of operations in accordance with GAAP. Furthermore, the Company excluded EC&S segment employees from the fiscal 2020 bonus compensation plan, accordingly there are no expenses associated with the plan for that period. ** In addition to the impairment & divestiture charges discussed above, the Company also incurred approximately $10.5 million of divestiture charges in fiscal 2019 related to the, at the time, anticipated divestiture of EC&S. Other Divestiture Activities On September 20, 2019, the Company completed the sale of the UNI-LIFT product line, a component of our Milwaukee Cylinder business (IT&S segment), for net cash proceeds of $7.5 million (inclusive of the settlement of working capital adjustments and the buyer achieving certain criteria which met the requirement for payment of $1.5 million of contingent proceeds). The transaction resulted in an impairment & divestiture benefit of $6.3 million for the year ended August 31, 2020 recorded as an "Impairment & divestiture benefit" within the Consolidated Statements of Operations. After the sale of the UNI-LIFT product line, the Company determined that the remaining Milwaukee Cylinder business was a non-core asset, did not align with the strategic objectives of the Company and, as a result, the Company committed to a plan to sell this business. The Company completed the divestiture of the Milwaukee Cylinder business on December 2, The historical results of the Milwaukee Cylinder business, inclusive of the UNI-LIFT product line, (which had net sales of $2.9 million and $13.2 million in the year ended August 31, 2020 and 2019, respectively) are not material to the consolidated financial results. On October 22, 2019, the Company completed the sale of the Connectors product line (IT&S segment) for net cash proceeds of $2.7 million, which resulted in an impairment & divestiture benefit of $1.0 million in the year ended August 31, 2020. The historical results of the Connectors product line (which had net sales of $0.2 million and $5.0 million for the year ended August 31, 2020 and 2019, respectively) are not material to the consolidated financial results.

Goodwill and Other Intangible Assets	Note 6. Goodwill, Intangible Assets and Long-Lived Assets Changes in the gross carrying value of goodwill and intangible assets result from changes in foreign currency exchange rates, business acquisitions, divestitures and impairment charges. The changes in the carrying amount of goodwill for the years ended August 31, 2021 and 2020 by operating segment are as follows (in thousands): IT&S Other Total Balance as of August 31, 2019 $ 242,873 $ 17,542 $ 260,415 Acquisition of HTL Group (Note 4) 11,261 — 11,261 Impact of changes in foreign currency rates 9,403 75 9,478 Balance as of August 31, 2020 263,537 17,617 281,154 Impairment charge — (5,656) (5,656) Impact of changes in foreign currency rates 1,550 545 2,095 Balance as of August 31, 2021 $ 265,087 $ 12,506 $ 277,593 The gross carrying value and accumulated amortization of the Company’s intangible assets are as follows (in thousands): Weighted Average Amortization Period (Year) August 31, 2021 August 31, 2020 Gross Accumulated Amortization Net Book Value Gross Accumulated Amortization Net Book Value Amortizable intangible assets: Customer relationships 14 $ 142,453 $ 114,463 $ 27,990 $ 141,853 $ 106,491 $ 35,362 Patents 12 14,492 13,688 804 14,365 13,228 1,137 Trademarks and tradenames 12 3,307 2,391 916 3,277 2,257 1,020 Indefinite lived intangible assets: Tradenames N/A 24,835 — 24,835 24,863 — 24,863 $ 185,087 $ 130,542 $ 54,545 $ 184,358 $ 121,976 $ 62,382 The Company estimates that amortization expense for future years is estimated to be $7.5 million in fiscal 2022, $5.9 million in fiscal 2023, $4.2 million in fiscal 2024, $3.5 million in fiscal 2025, $2.0 million in fiscal 2026 and $6.6 million in aggregate thereafter. The future amortization expense amounts represent estimates and may be impacted by future acquisitions, divestitures or changes in foreign currency exchange rates, among other causes. Fiscal 2021 Impairment Charges In the fourth quarter of fiscal 2021, the Cortland Industrial business lagged behind our IT&S segment with respect to recovery in demand from the COVID-19 pandemic. Further, though volumes did increase from previous quarters, it became clear that the business was not on track to realize the annual savings from the prior years' footprint optimization actions at the pace initially projected. Therefore, in conjunction with our annual goodwill impairment assessment , the Company recognized a $5.7 million goodwill impairment charge associated with the Cortland Industrial reporting unit (Other Segment) within "Impairment & divestiture charges (benefit)" in the Consolidated Statements of Operations. Fiscal 2019 Impairment Charges Within the Other segment, the Company recognized a $13.7 million goodwill impairment charge related to Cortland U.S. in conjunction with triggering events identified during the fiscal year.

Debt Disclosure [Abstract]
Debt	Note 7. Debt The following is a summary of the Company’s long-term indebtedness (in thousands): August 31, 2021 2020 Senior Credit Facility Revolver $ 175,000 $ 255,000 Total long-term debt, less current maturities $ 175,000 $ 255,000 Senior Credit Facility In March 2019, the Company entered into a senior credit facility (the "Senior Credit Facility") with a syndicate of banks, to among other things, (i) expand the multi-currency revolving line of credit from $300 million to $400 million, (ii) extend the maturity of the Company's Senior Credit Facility from May 2020 to March 2024 (no required principal payments prior to maturity) and (iii) modify certain other provisions of the credit agreement including a reduction in pricing. The Senior Credit Facility was initially comprised of a $400 million revolving line of credit and a $200 million term loan. In November 2019, the Company used the proceeds from the sale of the EC&S segment to pay off the outstanding principal balance on the term loan ($175.0 million). In conjunction with the repayment, the Company expensed, within "Financing costs, net" in the Consolidated Statements of Operations, the remaining $0.6 million of associated capitalized debt issuance costs. In June 2020, the Company borrowed $295.0 million under the Senior Credit Facility revolving line of credit, which was used by the Company to redeem all of the outstanding Senior Notes plus accrued interest (see additional information on the Senior Notes below). In conjunction with the redemption of the Senior Notes, the Company expensed, within "Financing costs, net" in the Consolidated Statements of Operations, the remaining $1.0 million of associated capitalized debt issuance costs. To reduce interest costs the Company paid down $80.0 million on the revolving line of credit in the year ended August 31, 2021, with available cash on hand. At August 31, 2021, there were $175 million borrowings under the revolving line of credit and $220.3 million of available borrowing capacity under the revolving line of credit. The Senior Credit Facility also provides the option for future expansion, subject to certain conditions, through a $300 million accordion and/or a $200 million incremental term loan. Borrowings under the Senior Credit Facility bear interest at a variable rate based on LIBOR or a base rate, ranging from 1.125% to 2.00% in the case of loans bearing interest at LIBOR and from 0.125% to 1.00% in the case of loans bearing interest at the base rate. In addition, a non-use fee was payable quarterly on the average unused amount of the revolving line of credit ranging from 0.15% to 0.3% per annum, based on the Company's net leverage. The Senior Credit Facility contains two financial covenants which are a maximum leverage ratio of 3.75:1 and a m inimum interest coverage ratio of 3.5:1. Certain transactions lead to adjustments to the underlying ratios, including an increase to the leverage ratio from 3.75 to 4.25 during the four fiscal quarters after a significant acquisition. The sale of the EC&S segment triggered a reduction of the minimum interest coverage ratio from 3.5 to 3.0 for any fiscal quarter ending within twelve months after the sale of the EC&S segment. In April 2020, the Company proactively amended its Senior Credit Facility to extend the interest coverage ratio at 3.0 for an additional 12 months through October 2021 to mitigate risks associated with the potential impact of the COVID-19 pandemic. The Company was in compliance with all financial covenants at August 31, 2021. Borrowings under the Senior Credit Facility are secured by substantially all personal property assets of the Company and its domestic subsidiary guarantors and certain equity interests owned by the foreign law pledgors. Senior Notes On April 16, 2012, the Company issued $300 million of 5.625% Senior Notes due 2022 (the “Senior Notes”), of which none remain outstanding. The Senior Notes included a call feature that allowed the Company to redeem them anytime on or after June 15, 2017 at stated redemption prices that reduced to 100% on June 15, 2020, plus accrued and unpaid interest. In order to reduce interest costs, in June 2020, the Company redeemed all of the outstanding Senior Notes at a price equal to 100% of the principal amount thereof, plus the settlement of accrued and unpaid interest.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8. Fair Value Measurements The Company assesses the inputs used to measure the fair value of financial assets and liabilities using a three-tier hierarchy. Level 1 inputs include unadjusted quoted prices for identical instruments and are the most observable. Level 2 inputs include quoted prices for similar assets and observable inputs such as interest rates, foreign currency exchange rates, commodity rates and yield curves. Level 3 inputs are not observable in the market and include management’s own judgments about the assumptions market participants would use in pricing an asset or liability. The fair value of the Company’s cash and cash equivalents, accounts receivable, accounts payable and variable rate long-term debt approximated book value at both August 31, 2021 and 2020 due to their short-term nature and the fact that the interest rates approximated market rates. Foreign currency exchange contracts and interest rate swaps are recorded at fair value. The fair value of the Company's foreign currency exchange contracts was a net liability of less than $0.1 million at August 31, 2021 and a net asset of less than $0.2 million at August 31, 2020. The fair value of the foreign currency exchange contracts were based on quoted inactive market prices and therefore classified as Level 2 within the valuation hierarchy. As discussed in Note 4, "Acquisitions" , the Company acquired HTL Group in the year ended August 31, 2020 and recorded the assets acquired and liabilities assumed at fair value, of which the most significant judgments were associated with intangible assets (including tradenames, customer relationships and patents) and property, plant and equipment. As discussed in Note 6, “Goodwill, Intangible Assets and Long-Lived Assets”

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 9. Derivatives All derivatives are recognized in the balance sheet at their estimated fair value. The Company does not enter into derivatives for speculative purposes. Changes in the fair value of derivatives (not designated as hedges) are recorded in earnings along with the gain or loss on the hedged asset or liability. The Company is exposed to market risk for changes in foreign currency exchange rates due to the global nature of its operations. In order to manage this risk, the Company utilizes foreign currency exchange contracts to reduce the exchange rate risk associated with recognized non-functional currency balances. The effects of changes in exchange rates are reflected concurrently in earnings for both the fair value of the foreign currency exchange contracts and the related non-functional currency asset or liability. These derivative gains and losses offset foreign currency gains and losses from the related revaluation of non-functional currency assets and liabilities (amounts included in "Other (income) expense" in the Consolidated Statements of Operations). The U.S. dollar equivalent notional value of these short duration foreign currency exchange contracts was $16.0 million and $16.7 million at August 31, 2021 and 2020, respectively. The fair value of outstanding foreign currency exchange contracts was a liability of less than $0.1 million at August 31, 2021 and an asset of less than $0.2 million at August 31, 2020. Net foreign currency losses (included in "Other expense (income)" in the Consolidated Statements of Operations) related to these derivative instruments are as follows (in thousands): Year Ended August 31, 2021 2020 2019 Foreign Currency losses $ (63) $ (594) $ (292) The Company was the fixed-rate payor on an interest rate swap contract that fixed the LIBOR-based index used to determine the interest rates charged on a total of $100.0 million of the Company's LIBOR-based variable rate borrowings on the revolving line of credit. The contract carried a fixed rate of 0.259% and expired in August 2021. The swap agreement qualified as a hedging instrument and was designated as a cash flow hedge of forecasted LIBOR-based interest payments. The change in the fair value of the interest rate swap, a gain of $0.1 million and a loss of $0.1 million in the year ended August 31, 2021 and 2020, respectively, was recorded in other comprehensive income.

Leases [Abstract]
Lessee, Operating Leases	Note 10. Leases As of August 31, 2021, the Company ha d operating leases for real estate, vehicles, manufacturing equipment, IT equipment and office equipment. The Company did not have significant finance leases during the year ended August 31, 2021 . Our leases typically range in term from 3 to 15 years and may contain renewal options for periods up to 5 years at our discretion. Our leases generally contain payments that are primarily fixed; however, certain lease arrangements contain variable payments, which are expensed as incurred and not included in the measurement of ROU assets and lease liabilities. These amounts include payments affected by changes in the Consumer Price Index and executory costs (such as real estate taxes, utilities and common-area maintenance), which are based on usage or performance. In addition, our leases generally do not include material residual value guarantees or material restrictive covenants. During the year ended August 31, 2021, the Company sold and subsequently leased back a portion of its manufacturing facility in China as part of a global footprint rationalization initiative. In connection with the transaction, the Company recognized a gain of $10.0 million. The gain is recorded in "Selling, general and administrative expenses" within the Consolidated Statements of Operations and in "Other non-cash (benefits) charges" within the Consolidated Statements of Cash Flows. The Company also incurred $4.6 million of closing related costs and value-added and land taxes associated with this transaction also included in "Selling, general and administrative expenses" within the Consolidated Statements of Operations.

The following table provides detail of changes in the projected benefit obligations, the fair value of plan assets and the funded status of the Company’s U.S. defined benefit pension plans as of the respective August 31 measurement date (in thousands): 2021 2020 Reconciliation of benefit obligations: Benefit obligation at beginning of year $ 49,640 $ 47,400 Interest cost 1,156 1,331 Actuarial (gain) loss (729) 4,131 Benefits paid (2,920) (3,222) Benefit obligation at end of year $ 47,147 $ 49,640 Reconciliation of plan assets: Fair value of plan assets at beginning of year $ 39,935 $ 40,412 Actual return on plan assets 1,990 2,562 Company contributions 691 183 Benefits paid from plan assets (2,920) (3,222) Fair value of plan assets at end of year 39,696 39,935 Funded status of the plans (underfunded) $ (7,451) $ (9,705) The following table provides detail on the Company’s domestic net periodic benefit expense (in thousands): Year ended August 31, 2021 2020 2019 Interest cost $ 1,156 $ 1,331 $ 1,694 Expected return on assets (1,610) (1,770) (2,208) Amortization of actuarial loss 1,322 1,212 990 Net periodic benefit expense $ 868 $ 773 $ 476 As of August 31, 2021 and 2020, $19.5 million and $21.4 million, respectively, of pension plan actuarial losses, which have not yet been recognized in net periodic benefit cost, were included in accumulated other comprehensive loss, net of income taxes. During fiscal 2022, $1.2 million of these actuarial losses are expected to be recognized in net periodic benefit cost. Weighted-average assumptions used to determine U.S. pension plan obligations as of August 31 and weighted-average assumptions used to determine net periodic benefit cost for the years ended August 31 are as follows: 2021 2020 2019 Assumptions for benefit obligations: Discount rate 2.55 % 2.40 % 2.90 % Assumptions for net periodic benefit cost: Discount rate 2.40 % 2.90 % 4.05 % Expected return on plan assets 4.20 % 4.60 % 5.75 % Prior to fiscal 2019, the Company focused on employing a total-return-on-investment approach for its pension plan assets whereby a mix of equity and fixed income investments were used to maximize the long-term return for plan assets, at prudent levels of risk. During fiscal 2019, the Company made a strategic decision to shift the focus to an objective to achieve an asset and liability duration match so that interim fluctuations in funded status should be limited by increasing the correlation between assets and liabilities. As such, the plan assets are invested to maintain funded ratios over the long term, while managing the risk that funded ratios fall meaningfully below 100%. At this time, the plan portfolio is significantly invested in duration-matched fixed income securities, which aligns to the plan's previously planned asset investment mix of 70% fixed income securities and 30% equity securities. Cash balances are maintained at levels adequate to meet near-term plan expenses and benefit payments. Based on the current funded status of the plan, the plan will rebalance with an investment mix of 50% fixed income securities and 50% equity securities by the end of the period ending November 30, 2021. Investment risk is measured and monitored on an ongoing basis. At August 31, 2021, the Company’s overall expected long-term rate of return for assets in U.S. pension plans was 5.45%. The expected long-term rate of return is based on the portfolio as a whole and not on the sum of the returns on individual asset categories. The target return is based on historical returns adjusted to reflect the current view of the long-term investment market and our updated 50% investment mix between fixed income and equity securities. The U.S. pension plan investment allocations by asset category were as follows (in thousands): Year Ended August 31, 2021 % 2020 % Cash and cash equivalents $ — — % $ — — % Income receivable 49 0.1 55 0.1 Fixed income securities: U.S. Treasury Securities 4,825 12.2 5,206 13.0 Corporate Bonds — — — — Mutual funds 23,564 59.3 23,091 57.9 28,389 71.5 28,297 70.9 Equity securities: Mutual funds 11,258 28.4 11,583 29.0 Total plan assets $ 39,696 100.0 % $ 39,935 100.0 % The fair value of mutual funds are based on unadjusted quoted market prices and therefore are classified as Level 1 within the fair value hierarchy under GAAP. U.S. Treasury Securities and Corporate Bonds are valued using Level 2 inputs, as defined in Note 8, “Fair Value Measurements.” Projected benefit payments from plan assets to participants in the Company’s U.S. pension plans are $2.9 million for fiscal 2022 and $3.1 million per year for each of the next four years and $14.5 million in aggregate for the following five years. The Company made a contribution of $0.6 million to the U.S. pension plans in September of fiscal 2021. The Company plans to contribute $0.1 million to the plan in fiscal 2022. Foreign Defined Benefit Pension Plans The Company has eight significant foreign defined benefit pension plans which cover certain existing and former employees of businesses outside the U.S. Most of the participants in the foreign defined benefit pension plans are inactive and no longer earning additional benefits. The following table provides detail of changes in the projected benefit obligations, the fair value of plan assets and the funded status of the Company’s significant foreign defined benefit pension plans as of the respective August 31 measurement date (in thousands): 2021 2020 Reconciliation of benefit obligations: Benefit obligation at beginning of year $ 14,297 $ 15,103 Employer service costs 116 284 Interest cost 198 171 Actuarial loss/(gain) 51 (495) Benefits paid (293) (300) Plan amendments — — Curtailments — (1,687) Currency impact 52 1,221 Benefit obligation at end of year $ 14,421 $ 14,297 Reconciliation of plan assets: Fair value of plan assets at beginning of year $ 8,980 $ 8,118 Actual return on plan assets 532 69 Company contributions 56 323 Benefits paid from plan assets (293) (300) Currency impact 121 770 Fair value of plan assets at end of year 9,396 8,980 Funded status of the plans (underfunded) $ (5,025) $ (5,317) The following table provides detail on the Company’s foreign net periodic benefit expense (in thousands): Year ended August 31, 2021 2020 2019 Employer service costs $ 116 $ 284 $ 450 Interest cost 198 171 257 Expected return on assets (347) (357) (345) Amortization of net prior service credit 4 (18) (65) Amortization of net loss 139 205 263 Income of special events — (728) (56) Net periodic benefit expense (income) $ 110 $ (443) $ 504 The weighted average discount rate utilized for determining the benefit obligation at August 31, 2021 and 2020 was 1.3% and 1.4%, respectively. The plan assets of these foreign pension plans consist primarily of participating units in fixed income and equity securities and insurance contracts. The Company’s overall expected long-term rate of return on these investments is 3.9%. During fiscal 2022, the Company does not anticipate contributing to these pension plans. In fiscal 2020, the Company moved certain employees in a foreign pension plan into a multi-employer pension plan which triggered a curtailment. The curtailment resulted in a reduction to the projected benefit obligation of that plan of $1.7 million, of which $0.7 million was recorded as a component of Other expense (income), net within the Consolidated Statements of Operations and the remaining $1.0 million was recorded through Other comprehensive income on the Consolidated Statements of Comprehensive Income (Loss). Projected benefit payments to participants in the these foreign plans are $0.3 million in each of the following five fiscal years and $2.2 million in aggregate for the following five years. Other Postretirement Health Benefit Plans The Company provides other postretirement health benefits (“OPEB”) to certain existing and former employees of domestic businesses it acquired, who were entitled to such benefits prior to acquisition. These unfunded plans had a benefit obligation of $2.3 million and $2.4 million at August 31, 2021 and 2020, respectively. These obligations are determined utilizing assumptions consistent with those used for our U.S. pension plans and a health care cost trend rate of 6.5%, trending downward to 5.0% by the year 2026, and remaining level thereafter. Net periodic benefit costs for other postretirement benefits was income of $0.2 million, $0.3 million and $0.1 million for the year ended August 31, 2021, 2020 and 2019, respectively. Benefit payments from the plan are funded through participant contributions and Company contributions. Benefit payments are projected to be $0.2 million in fiscal 2022. Defined Contribution Benefit Plans The Company maintains a 401(k) plan for substantially all full time U.S. employees (the “401(k) Plan”). Under plan provisions, the Company can fund either cash or issue new shares of Class A common stock for its contributions. Amounts are allocated to accounts set aside for each employee’s retirement. Employees generally may contribute up to 50% of their compensation to individual accounts within the 401(k) Plan. While contributions vary, the Company's match contribution is $0.50 for every $1 contributed by employees, up to 8% of the employees' eligible pay. These match contributions are made on every payroll run, meaning the contribution is immediately 100% vested. In response to the COVID-19 pandemic, the Company temporarily suspended its 401(k) match in May 2020 (fiscal 2020) and reinstated the 401(k) match in January 2021 (fiscal 2021). In addition, the Company may make an annual, discretionary contribution of up to 3% of employees' eligible pay to employees employed as of the end of the plan year. The discretionary contribution has a three-year vesting period. The Company elected not to provide a discretionary contribution for the year ended August 31, 2021. The Company also maintains a Restoration Plan that allows eligible highly compensated employees (as defined by the Internal Revenue Code) to receive a core contribution as if no IRS limits were in place. Company contributions to the Restoration Plan are made in the form of its Class A common stock and contributed into each eligible participant’s deferred compensation plan. In fiscal 2019 the Company contributed $0.1 million to eligible participants; no contributions were made in fiscal 2021 or 2020.

Income Taxes	Note 12. Income Taxes Earnings (loss) before income taxes from continuing operations, are summarized as follows (in thousands): Year Ended August 31, 2021 2020 2019 Domestic $ 1,292 $ (9,058) $ (715) Foreign 42,683 16,907 19,439 $ 43,975 $ 7,849 $ 18,724 Both domestic and foreign pre-tax earnings from continuing operations are impacted by changes in operating earnings, acquisition and divestiture activities, restructuring charges and the related benefits, growth investments, debt levels and the impact of changes in foreign currency exchange rates. In fiscal 2021, domestic and foreign earnings included non-cash impairment and other divestiture charges of $4.7 million and $1.5 million, respectively. In fiscal 2020, domestic and foreign earnings included non-cash impairment and other divestiture benefits of $(2.6) million and $(0.6) million, respectively. In fiscal 2019, domestic and foreign earnings included $9.0 million and $13.8 million of non-cash impairment and other divestiture costs. Income tax expense from continuing operations is summarized as follows (in thousands): Year ended August 31, 2021 2020 2019 Currently payable: Federal $ (18,243) $ (35) $ (2,040) Foreign 12,441 10,004 9,370 State 539 142 1,347 (5,263) 10,111 8,677 Deferred: Federal 9,677 (7,791) (400) Foreign 185 (1,632) 2,172 State (836) 1,604 208 9,026 (7,819) 1,980 Income tax expense $ 3,763 $ 2,292 $ 10,657 Income tax expense from continuing operations recognized in the accompanying consolidated statements of operations differs from the amounts computed by applying the federal income tax rate to earnings from continuing operations before income tax expense. A reconciliation of income taxes at the federal statutory rate to the effective tax rate is summarized in the following table: Year ended August 31, 2021 2020 2019 Federal statutory rate 21.0 % 21.0 % 21.0 % State income taxes, net of Federal effect (0.2) (0.6) (4.0) Tax on foreign earnings (1) 2.8 38.7 20.6 Foreign derived intangible income deduction (3.2) — (9.3) Compensation adjustment 3.1 6.6 4.4 Impairment and other divestiture charges (2) 1.6 3.3 19.3 Valuation allowance additions and releases (3) 7.1 (8.1) 3.9 Changes in liability for unrecognized tax benefits (18.5) (5.3) 4.1 U.S. legislative changes, net impact (9.8) (32.5) (31.1) Taxable liquidation of subsidiaries (4) — 52.6 — Foreign non-deductible expenses 1.2 7.4 18.2 Changes in tax rates (3.4) (9.0) 1.7 Audits and adjustments (5) 8.0 (27.4) 10.0 Research and development tax credit (1.8) (11.5) (5.2) Other items 0.7 (6.0) 3.3 Effective income tax rate 8.6 % 29.2 % 56.9 % (1) The Company generated $1.7 million, $5.4 million and $2.6 million of withholding tax expense for fiscal 2021, 2020 and 2019, respectively, and $4.6 million, $4.0 million and $3.5 million of foreign-derived tax credits, excluding the impact of tax reform for fiscal 2021, 2020 and 2019, respectively. (2) Fiscal 2021, 2020 and 2019 pretax earnings include $6.2 million, $(3.2) million and $22.8 million, respectively, in impairment & divestiture charges (benefits) related to goodwill, intangible assets, tangible assets and the cumulative effect of foreign currency rate changes of which $3.5 million, $0.3 million and $14.0 million, respectively, are not deductible for income tax purposes. (3) Incremental valuation allowances of $4.9 million and $9.4 million and $1.7 million were recorded in fiscal 2021, 2020 and 2019, respectively, due to uncertainty regarding realization of tax assets, which were offset by a reduction of $9.1 million, $12.3 million and $2.9 million of valuation allowances for fiscal 2021, 2020 and 2019, respectively. These amounts exclude valuation allowances against tax assets related to the tax reform. (4) During fiscal 2020, the Company generated a net expense of $4.1 million as a result of taxable liquidations of subsidiaries. (5) During fiscal 2021, the Company generated $3.5 million of tax benefit related to audits and adjustments as compared to a tax benefit of $2.2 million in fiscal 2020 and a tax expense of $1.9 million in fiscal 2019. Temporary differences and carryforwards that gave rise to deferred tax assets and liabilities include the following items (in thousands): August 31, 2021 2020 Deferred income tax assets: Operating loss and tax credit carryforwards $ 77,691 $ 99,905 Compensation related liabilities 6,110 5,941 Postretirement benefits 8,364 9,068 Inventory 3,177 1,793 Lease liabilities 11,609 10,526 Book reserves and other items 11,471 6,752 Total deferred income tax assets 118,422 133,985 Valuation allowance (66,155) (70,414) Net deferred income tax assets 52,267 63,571 Deferred income tax liabilities: Depreciation and amortization (29,444) (31,457) Lease assets (11,609) (10,526) Other items (781) (702) Deferred income tax liabilities (41,834) (42,685) Net deferred income tax asset (1) $ 10,433 $ 20,886 (1) The net deferred income tax asset is reflected on the balance sheet in two categories: an asset of $14.8 million and $22.6 million for fiscal 2021 and 2020, respectively, is included in "Other long-term assets" and a liability of $4.4 million and $1.7 million for fiscal 2021 and 2020, respectively, is included in "Deferred income taxes". The Company has $65.1 million and $2.4 million of gross state net operating loss and credit carryforwards, respectively, which are available to reduce future state tax liabilities. These state net operating loss carryforwards expire at various times through 2041. The Company also has $86.3 million and $7.8 million of foreign loss and credit carryforwards, respectively, and $3.4 million of U.S. credit carryforwards which are available to reduce certain future foreign and U.S. tax liabilities. Over half of the foreign loss carryforwards are not subject to any expiration dates, while the other balances expire at various times through 2031. The U.S. credit carryforwards expire at various times through 2040. The valuation allowance represents a reserve for deferred tax assets, including loss carryforwards and foreign tax credits, for which utilization is uncertain. The Company’s policy is to remit earnings from foreign subsidiaries only to the extent the remittance does not result in an incremental U.S. tax liability. The Company does not currently provide for the additional U.S. and foreign income taxes which would become payable upon remission of undistributed earnings of foreign subsidiaries. If all undistributed earnings were remitted, an additional income tax provision of $3.7 million would have been necessary as of August 31, 2021. Changes in the Company’s gross liability for unrecognized tax benefits, excluding interest and penalties, are as follows (in thousands): 2021 2020 2019 Beginning balance $ 23,205 $ 24,167 $ 24,359 Increases based on tax positions related to the current year 381 869 2,169 Increase for tax positions taken in a prior period 7 304 1,422 Decrease due to lapse of statute of limitations (7,931) (2,334) (3,212) Decrease due to settlements — — (324) Changes in foreign currency exchange rates (4) 199 (247) Ending balance $ 15,658 $ 23,205 $ 24,167 Substantially all of these unrecognized tax benefits, if recognized, would impact the effective income tax rate. As of August 31, 2021, 2020 and 2019, the Company recognized $3.9 million, $4.5 million and $3.7 million, respectively, for interest and penalties related to unrecognized tax benefits. The Company recognizes interest and penalties related to underpayment of income taxes as a component of income tax expense. With few exceptions, the Company is no longer subject to U.S. federal, state and foreign income tax examinations by tax authorities in major tax jurisdictions for years prior to fiscal 2010. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits could decrease by up to $1.0 million throughout fiscal 2022.

The Plan permits the Company to grant share-based awards, including stock options, restricted stock, restri cted stock units and performance shares (the "Performance Shares") to employees and directors. Options generally have a maximum term of ten years, an exercise price equal to 100% of the fair market value of the Company’s common stock at the date of grant and generally vest 50% after three years and 100% after five years. The Company’s restricted stock grants prior to 2017 generally have similar vesting provisions as options, while grants thereafter generally vest in equal installments over a three-year period. The Performance Shares include a three A summary of restricted stock units and performance shares activity during fiscal 2021 is as follows: Number of Weighted-Average Fair Value at Grant Date (Per Share) Outstanding on August 31, 2020 986,121 $24.10 Granted 515,469 22.44 Forfeited (76,989) 25.30 Vested (406,943) 23.84 Outstanding on August 31, 2021 1,017,658 $23.27 A summary of stock option activity during fiscal 2021 is as follows: Shares Weighted-Average Weighted-Average Aggregate Outstanding on September 1, 2020 1,455,041 $ 26.45 Granted — — Exercised (152,680) 22.62 Forfeited — — Expired (312,893) 27.56 Outstanding on August 31, 2021 989,468 $ 26.69 3.6 $ 1,013,960 Exercisable on August 31, 2021 926,343 $ 26.67 3.5 $ 1,013,960 Intrinsic value is the difference between the market value of the stock at August 31, 2021 and the exercise price which is aggregated for all options outstanding and exercisable.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Litigation	Note 16. Commitments and Contingencies The Company had outstanding letters of credit of $11.9 million at both August 31, 2021 and 2020, the majority of which relate to commercial contracts and self-insured workers' compensation programs. As part of the Company's global sourcing strategy, we have entered into agreements with certain suppliers that require the supplier to maintain minimum levels of inventory to support certain products for which we require a short lead time to fulfill customer orders. We have the ability to notify the supplier that they no longer need maintain the minimum level of inventory should we discontinue manufacture of a product during the contract period, however, we must purchase the remaining minimum inventory levels the supplier was required to maintain within a defined period of time. The Company is a party to various legal proceedings that have arisen in the normal course of business. These legal proceedings typically include product liability, breaches of contract, employment, personal injury and other disputes. The Company has recorded reserves for loss contingencies based on the specific circumstances of each case. Such reserves are recorded when it is probable a loss has been incurred and can be reasonably estimated. The Company maintains a policy to exclude from such reserves an estimate of legal defense costs. In the opinion of management, resolution of these contingencies is not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. The Company remains contingently liable for lease payments under leases of businesses that it previously divested or spun-off in the event that such businesses are unable to fulfill their future lease payment obligations, however, the Company does not believe it is probable that it will be required to satisfy these obligations. Future minimum lease payments for these leases at August 31, 2021 were $5.3 million associated with monthly payments extending to fiscal 2025. The Company has facilities in numerous geographic locations that are subject to environmental laws and regulations. Environmental expenditures over the past three years have not been material. Soil and groundwater contamination has been identified at certain facilities that we operate or formerly owned or operated. We are also a party to certain state and local environmental matters, have provided environmental indemnifications for certain divested businesses and retain responsibility for certain potential environmental liabilities. Management believes that such costs will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. Additionally, the Company self-disclosed in fiscal 2019 the sales to an Estonian customer to relevant authorities in the Netherlands as potentially violating applicable Crimea sanctions laws in that country and the European Union, as those products were used in the Crimea region of Ukraine. While the investigation by authorities in the Netherlands is ongoing, the Company has concluded that it is probable it will incur financial penalties. While there can be no assurance of the ultimate outcome of the Netherlands investigation, in the year ended August 31, 2021 the Company recorded an expense representing its estimate of the financial penalty it may incur. The Company currently believes that there will be no material adverse effect on the Company's financial position, results of operations or cash flows from this matter.

Cash Equivalents	Cash Equivalents: The Company considers all highly liquid investments with original maturities of 90 days or less to be cash equivalents.
Inventories	Inventories: Inventories are comprised of material, direct labor and manufacturing overhead. A majority of inventory is recorded on the first-in, first-out or average cost method and is stated at the lower of cost or net realizable value. A portion of U.S. owned inventory is determined using the last-in, first-out (“LIFO”) method (48.4% a nd 44.1% of total inventories as of August 31, 2021 and 2020, respectively). If the LIFO method were not used, inventory balances would be higher than reported amounts in the consolidated balance sheets b y $15.9 million and $10.2 million at August 31, 2021 and 2020, respectively. The nature of the Company’s products is such that they generally have a very short production cycle. Consequently, the amount of work-in-process at any point in time is minimal. In addition, many parts or components are ultimately either sold individually or assembled with other parts making a distinction between raw materials and finished goods impractical to determine. Certain locations maintain and manage their inventories using a job cost system where the distinction of categories of inventory by state of completion is also not available. As a result of these factors, it is neither practical nor cost effective to segregate the amounts of raw materials, work-in-process or finished goods inventories at the respective balance sheet dates, as segregation would only be possible as the result of physical inventories which are taken at dates different from the balance sheet dates.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets: Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are subject to annual impairment testing. Other intangible assets with definite lives, consisting primarily of purchased customer relationships, patents, trademarks and tradenames, are amortized over periods from one to twenty-five years. The Company’s goodwill is tested for impairment annually, during the fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill might be impaired. The Company performs impairment reviews for its reporting units using a fair value method based on management’s judgments and assumptions. In estimating the fair value, the Company utilizes a discounted cash flow model, which is dependent on a number of assumptions, most significantly forecasted revenues and operating profit margins, and the weighted average cost of capital. The estimated fair value of the reporting unit is compared to the carrying amount of the reporting unit, including goodwill. If the carrying value of the reporting unit exceeds its fair value, an impairment loss is recorded and should not exceed the total amount of the goodwill allocated to the reporting unit. Indefinite-lived intangible assets are also subject to an annual impairment test. On an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired, the fair value of the indefinite-lived intangible assets are evaluated by the Company to determine if an impairment charge is required. A considerable amount of management judgment is required in performing impairment tests, principally in determining the fair value of each reporting unit and the indefinite-lived intangible assets.
Property, Plant and Equipment	Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated on a straight-line basis over the estimated useful lives of the assets, ranging from ten two ase. Depreciation expense was $13.4 million, $12.4 million and $11.3 million for the years ended August 31, 2021, 2020 and 2019, respectively. The following is a summary of the Company's components of property, plant and equipment (in thousands): August 31, 2021 August 30, 2020 Land, buildings and improvements $ 16,617 $ 33,548 Machinery and equipment 145,541 134,536 Gross property, plant and equipment 162,158 168,084 Less: Accumulated depreciation (113,568) (106,679) Property, plant and equipment, net $ 48,590 $ 61,405

Product Warranty Costs	Product Warranty Costs : The Company generally offers its customers an assurance warranty on products sold, although warranty periods may vary by product type and application. The reserve for future warranty claims, which is recorded within the "Other current liabilities" line on the Consolidated Balance Sheets, is based on historical claim rates and current warranty cost experience. The following is a rollforward of the changes in product warranty reserves for fiscal years 2021 and 2020 (in thousands): 2021 2020 Beginning balance $ 892 $ 1,145 Provision for warranties 1,580 677 Warranty payments and costs incurred (1,171) (934) Warranty activity for divested businesses — (27) Impact of changes in foreign currency rates (1) 31 Ending balance $ 1,300 $ 892
Revenue Recognition	Revenue from Contracts with Customers: The Company recognizes revenue when it satisfies a performance obligation in a contract by transferring control of a distinct good or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation and revenue is measured based on the consideration that the Company expects to be entitled to in exchange for the goods or services transferred. When contracts include multiple products or services to be delivered to the customer, the consideration for each element is generally allocated on the standalone transaction prices of the separate performance obligations, using the adjusted market assessment approach. Under normal circumstances, the Company invoices the customer once transfer of control has occurred and has a right to payment. The typical payment terms vary based on the customer and the types of goods and services in the contract. The period of time between invoicing and when payment is due is not significant, as our standard payment terms are less than one year. Amounts billed and due from customers are classified as receivables on the balance sheet. Customer sales are recorded net of allowances for returns and discounts, which are recognized as a deduction from sales at the time of sale. The Company commits to one-time or on-going trade discounts and promotions with customers that require the Company to estimate and accrue the ultimate costs of such programs.The Company generally does not require collateral or other security for receivables and provides for an allowance for doubtful accounts based on historical experience and a review
Research and Development Costs	Research and Development Costs: Research and development costs consist primarily of an allocation of overall engineering and development resources and are expensed as incurred. Such costs incurred in the development of new products or significant improvements to existing pr oducts were $7.4 million, $7.3 million and $9.3 million in fiscal 2021, 2020 and 2019, respectively. The Company also incurs significant costs in connection with fulfilling custom orders and developing solutions for unique customer needs which are not included in these research and development expense totals.
Other Income/Expense	Other Income/Expense: Other income and expense primarily consists of net foreign currency exchange transaction losses of $1.8 million, $2.6 million and $0.2 million in fiscal 2021, 2020 and 2019, respectively. In addition, as a result of the EC&S divestiture and the transition services agreement entered into with the buyer, the Company recorded $4.9 million of other income from providing the agreed upon services in fiscal 2020 .
Financing Costs	Financing Costs: Financing costs represent interest expense, financing fees and amortization of debt issuance costs, net of interest income. Interest income was $0.7 million, $0.8 million and $0.7 million for fiscal 2021, 2020 and 2019, respectively.
Income Taxes	Income Taxes: The provision for income taxes includes federal, state, local and non-U.S. taxes on income. Tax credits, primarily for non-U.S. earnings, are recognized as a reduction of the provision for income taxes in the year in which they are available for U.S. tax purposes. Deferred taxes are provided on temporary differences between assets and liabilities for financial and tax reporting purposes as measured by enacted tax rates expected to apply when temporary differences are settled or realized. Future tax benefits are recognized to the extent that realization of those benefits is considered to be more likely than not. A valuation allowance is established for deferred tax assets for which realization is not more likely than not of being realized. The Company has not provided for any residual U.S. income taxes on unremitted earnings of non-U.S. subsidiaries, as such earnings are intended to be indefinitely reinvested to the extent the remittance does not result in an incremental U.S. tax liability. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense and treats any taxes due on future U.S. inclusions in taxable income under the Global Intangible Low-Taxed Income ("GILTI") provision as a current period tax expense.
Foreign Currency Translation	Foreign Currency Translation: The financial statements of the Company’s foreign operations are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and an appropriate weighted average exchange rate for each applicable period within the Consolidated Statements of Operations. Translation adjustments are reflected in the Consolidated Balance Sheets and Consolidated Statements of Shareholders' Equity caption “Accumulated other comprehensive loss.”
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Loss: The following is a summary of the components included within accumulated other comprehensive loss (in thousands): August 31, 2021 2020 Foreign currency translation adjustments $ 69,986 $ 75,896 Pension and other postretirement benefit plans 22,998 24,750 Unrecognized losses on cash flow hedges — 78 Accumulated other comprehensive loss $ 92,984 $ 100,724
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The Company regularly evaluates the estimates and assumptions related to the allowance for doubtful accounts, inventory valuation, warranty reserves, goodwill, intangible and long-lived asset valuations, employee benefit plan liabilities, over-time revenue recognition, income tax liabilities, deferred tax assets and related valuation allowances, uncertain tax positions, restructuring reserves, and litigation and other loss contingencies. The COVID-19 pandemic has negatively impacted, and is likely to continue to negatively impact to varying extents, the global economy. The Company's operating results and financial position will continue to be subject to the general economic conditions created by the pandemic, and the duration and extent to which the pandemic's effects impact the Company's business will depend on future developments, including the distribution and long-term effectiveness of vaccines globally, the impact of COVID-19 variants, such as the Delta variant, and the impact of therapeutics in minimizing its negative effects on macroeconomic conditions, which still remain uncertain. The Company manages the profitability of its product and service & rental categories on a combined basis given the complexity of the business model. This model includes providing integrated product and service solutions resulting in facilities that generate revenues from both product and service & rental categories, which also have indirect and facility overhead costs included in cost of sales. As such, judgment and estimates are required to disaggregate product and service & rental cost of sales including allocating indirect and facility overhead costs between cost of product sales and the cost of service & rental sales. Changes in these judgments and estimates could materially change the allocation of the indirect and facility overhead costs to the different sales categories and the resulting ratio of cost of sales to net sales by category. Because the sales mix heavily favors the product category, a change in the mix of cost of sales between the sales categories would have a more significant impact on the ratio of cost of sales to net sales for the service & rental category. In addition, due to the recent changes in our business model, which includes the integration of the Enerpac and Hydratight businesses within the IT&S segment, the decision to exit certain non-strategic businesses and product lines, and the restructuring actions taken by the Company, the historical ratios of cost of sales to net sales by category may not be indicative of future ratios of cost of sales to net sales by category.
New Accounting Pronouncements, Policy	Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which adds an impairment model that is based on expected losses rather than incurred losses and is called the Current Expected Credit Losses (“CECL”) model. This impairment model is applicable to loans, debt securities, trade receivables, net investments in leases, off-balance sheet credit exposures, reinsurance receivables as well as any other financial asset with the contractual right to receive cash. Under the new model, an allowance equal to the estimate of lifetime expected credit losses is recognized which will result in more timely loss recognition. The guidance is intended to reduce complexity by decreasing the number of credit impairment models. The Company adopted the guidance on September 1, 2020 using the modified retrospective approach and there was no impact to the financial statements as a result of the adoption. In February 2016, the FASB issued ASU 2016-02, Leases (and subsequently ASU 2018-01 and ASU 2019-01), to increase transparency and comparability among organizations by recognizing all lease transactions on the balance sheet as a lease liability and a right-of-use (“ROU”) asset. The amendments also expanded disclosure requirements for key information about leasing arrangements. On September 1, 2019, the Company adopted the standard using a modified retrospective approach and elected the package of practical expedients allowing us to not reassess whether any expired or existing contracts contain leases, the lease classification for any expired or existing leases, and initial direct costs for leases that commenced prior to September 1, 2019. In addition, we elected not to recognize ROU assets or lease liabilities for leases containing terms of 12 months or less and not separate lease components from non-lease components for all asset classes. The Company updated its standard lease accounting policy to address the new standard, revised the Company’s business processes and controls to align to the updated policy and new standard and completed the implementation of and data input into the Company’s lease accounting software solution. The most significant impact of the standard on the Company was the recognition of a $60.8 million ROU asset and operating lease liability on the Consolidated Balance Sheets at adoption. The standard did not have a significant impact on our Consolidated Statements of Operations or Consolidated Statements of Cash Flows. In addition, as a result of sale leaseback transactions in previous years for which gains were deferred and under the new standard would have been recognized, the Company recorded an increase to retained earnings of $0.2 million in the first quarter of fiscal 2020, which represents the recognition of these previously deferred gains. See Note 10, “Leases” for further discussion of the Company’s operating leases. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for a limited time to ease the potential burden of accounting for reference rate reform on financial reporting. This guidance applies to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates. The guidance is effective beginning on March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01 allowing entities to apply certain aspects of ASC 848 (previously ASU 2020-4) to all derivative instruments that undergo a modification of the interest rate used for discounting, margining or contract price alignment as a result of the reference reform. The guidance is also effective through December 31, 2022. The Company has not utilized any of the optional expedients or exceptions available under this guidance. The Company will continue to assess whether this guidance is applicable throughout the effective period.
