Rate Reconciliation A reconciliation of the income tax rate computed by applying the statutory U.S. federal income tax rate to income before income taxes and losses of unconsolidated affiliate to the total income tax expense is as follows: Years Ended July 31, 2021 2020 2019 Tax at statutory rate 21.0 % 21.0 % 21.0 % International rate differential (1) 2.3 % 5.1 % 2.0 % Adjustments to tax accruals and reserves (2) 3.3 % (2.0) % (3.6) % Research and development tax credits and domestic manufacturer’s deduction (1.6) % (2.0) % (1.6) % Valuation allowance against foreign net operating loss carry-forwards (3) (4.8) % — % 0.2 % Deferred tax and other adjustments, net 0.6 % (2.0) % 2.3 % Income tax rate 20.8 % 20.1 % 20.3 % (1) Represents the foreign income tax rate differential when compared to the U.S. statutory income tax rate for the years ended July 31, 2021, 2020, and 2019. (2) The years ended July 31, 2021, 2020, and 2019, include reductions of uncertain tax positions resulting from the closure of audits and lapses in statues of limitations. The year ended July 31, 2021 was impacted by the recording of reserves for uncertain tax provisions. (3) The year ended July 31, 2021 includes a reduction in a previously recorded valuation allowance against certain foreign net operating loss carry-forwards. Uncertain Tax Positions The Company follows the guidance in ASC 740, "Income Taxes" regarding uncertain tax positions. The guidance requires application of a more-likely-than-not threshold to the recognition and de-recognition of income tax positions. A reconciliation of unrecognized tax benefits (excluding interest and penalties) is as follows: Balance as of July 31, 2018 $ 20,430 Additions based on tax positions related to the current year 2,518 Additions for tax positions of prior years 612 Reductions for tax positions of prior years (378) Lapse of statute of limitations (8,140) Cumulative translation adjustments and other (201) Balance as of July 31, 2019 $ 14,841 Additions based on tax positions related to the current year 2,798 Additions for tax positions of prior years 1,295 Reductions for tax positions of prior years (5,087) Lapse of statute of limitations (117) Cumulative translation adjustments and other (108) Balance as of July 31, 2020 $ 13,622 Additions based on tax positions related to the current year 4,664 Additions for tax positions of prior years (1) 3,940 Reductions for tax positions of prior years (365) Lapse of statute of limitations (159) Cumulative translation adjustments and other 210 Balance as of July 31, 2021 $ 21,912 (1) Includes acquisitions. Of the $21,912 of unrecognized tax benefits, if recognized, $18,717 would affect the Company's income tax rate. The Company has classified $15,427 and $8,931, excluding interest and penalties, of the reserve for uncertain tax positions in "Other liabilities" on the Consolidated Balance Sheets as of July 31, 2021 and 2020, respectively. The Company has classified $6,485 and $4,691, excluding interest and penalties, as a reduction of long-term deferred income tax assets on the accompanying Consolidated Balance Sheets as of July 31, 2021 and 2020, respectively. Interest expense is recognized on the amount of potentially underpaid taxes associated with the Company's tax positions, beginning in the first period in which interest starts accruing under the respective tax law and continuing until the tax positions are settled. The Company recognized interest (expense) and benefits of ($596), $372, and $1,013 on the reserve for uncertain tax positions during the years ended July 31, 2021, 2020, and 2019, respectively. The Company also recognized (expenses) and benefits related to penalties of ($595), $96, and $2,357 during the years ended July 31, 2021, 2020, and 2019, respectively. These amounts are net of reversals due to reductions for tax positions of prior years, statute of limitations, and settlements. At July 31, 2021 and 2020, the Company had $2,297 and $1,354, respectively, accrued for interest on unrecognized tax benefits. Penalties are accrued if the tax position does not meet the minimum statutory threshold to avoid the payment of a penalty. At July 31, 2021 and 2020, the Company had $2,098 and $658, respectively, accrued for penalties on unrecognized tax benefits. Interest expense and penalties are recorded as a component of "Income tax expense" in the Consolidated Statements of Income. The Company estimates that it is reasonably possible that the unrecognized tax benefits may be reduced by $3,253 during the year ending July 31, 2022 as a result of the resolution of worldwide tax matters, tax audit settlements, amended tax filings, and/or the expiration of statute of limitations, all of which, if recognized, would result in an income tax benefit in the Consolidated Statements of Income. During the year ended July 31, 2021, the Company recognized $295 of tax benefits (including interest and penalties) associated with the lapse of statutes of limitations. The Company and its subsidiaries file income tax returns in the U.S., various states, and foreign jurisdictions.

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Nature of Operations — Brady Corporation is a global manufacturer and supplier of identification solutions and workplace safety products that identify and protect premises, products and people. The ability to provide customers with a broad range of proprietary, customized, and diverse products for use in various applications, along with a commitment to quality and service, a global footprint, and multiple sales channels, have made Brady a world leader in many of its markets. Principles of Consolidation — The accompanying consolidated financial statements include the accounts of Brady Corporation and its wholly owned subsidiaries. All intercompany accounts and transactions between consolidated subsidiaries have been eliminated in consolidation. Use of Estimates — The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"), which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Acquisitions — The Company recognizes assets acquired, liabilities assumed, contractual contingencies and contingent consideration at their fair value on the acquisition date. The operating results of the acquired companies are included in the Company’s consolidated financial statements from the date of acquisition. Acquisition-related costs are expensed as incurred and changes in deferred tax asset valuation allowances and income tax uncertainties after the measurement period are recorded in Provision for Income Taxes. Cash Equivalents — The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. Concentration of Credit Risk — The Company places temporary cash investments with global financial institutions of high credit quality. The Company performs periodic evaluations of the relative credit standing of its financial institutions and limits the amount of credit exposure with any one financial institution. In addition, the Company has a broad customer base representing many diverse industries throughout the globe. Consequently, no significant concentration of credit risk is considered to exist. Accounts Receivables — The Company's policy for estimating the allowance for credit losses on accounts receivables considers several factors including historical loss experience, the age of delinquent receivable balances due, and economic conditions. Specific customer reserves are made during review of significant outstanding balances due, in which customer creditworthiness and current economic trends may indicate that it is probable the receivable will not be recovered. Accounts receivables are written off after collection efforts occur and the receivable is deemed uncollectible. Adjustments to the allowance for credit losses are recorded in SG&A expense. Equity Method Investment — The equity method of accounting is applied to investments in which the Company has an ownership interest of between 20% and 50%. The Company evaluates its equity method investments each reporting period for evidence of a loss in value that is other than a temporary decline. Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain an earnings capacity that would justify the carrying amount of the investment. The Company performed this analysis and concluded that its investment in React Mobile, Inc. was other-than-temporarily impaired and recognized an impairment charge of $4,994 for the year ended July 31, 2021. Inventories — Inventories are stated at the lower of cost or net realizable value and include material, labor, and overhead. Cost has been determined using the last-in, first-out (“LIFO”) method for certain inventories in the U.S. (12.5% of total inventories at July 31, 2021, and 14.7% of total inventories at July 31, 2020) and the first-in, first-out (“FIFO”) or average cost methods for all other inventories. Had all inventories been accounted for on a FIFO basis instead of on a LIFO basis, the carrying value of inventories would have increased by $7,707 and $7,195 as of July 31, 2021 and 2020, respectively. Inventories consist of the following as of July 31: 2021 2020 Finished products $ 87,489 $ 85,547 Work-in-process 20,189 24,044 Raw materials and supplies 28,429 26,071 Total inventories $ 136,107 $ 135,662 Property, Plant and Equipment — Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed primarily on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective asset. The estimated useful lives range from 3 to 33 years as shown below. Property, plant and equipment consist of the following as of July 31: Range of Useful Lives 2021 2020 Land $ 8,201 $ 9,960 Buildings and improvements 10 to 33 Years 108,801 105,129 Machinery and equipment 3 to 10 Years 276,994 267,795 Construction in progress 4,991 8,432 Property, plant and equipment—gross 398,987 391,316 Accumulated depreciation (277,246) (276,248) Property, plant and equipment—net $ 121,741 $ 115,068 Depreciation expense was $18,406, $18,218, and $18,023 for the years ended July 31, 2021, 2020 and 2019, respectively. Goodwill — The Company evaluates the carrying amount of goodwill annually or more frequently if events or changes in circumstances have occurred that indicate the goodwill might be impaired. The Company completes impairment reviews for its reporting units using a fair-value method based on management's judgments and assumptions. When performing its annual impairment assessment, the Company evaluates the recoverability of goodwill assigned to each of its reporting units by comparing the estimated fair value of the respective reporting unit to the carrying value, including goodwill. The Company estimates fair value utilizing the income approach and the market approach. The income approach requires management to make a number of assumptions and estimates for each reporting unit, including projected future operating results, economic projections, anticipated future cash flows, working capital levels, income tax rates, and a weighted-average cost of capital reflecting the specific risk profile of the respective reporting unit. The market approach estimates fair value using performance multiples of comparable publicly-traded compa nies. In the event the fair value of a reporting unit is less than the carrying value, including goodwill, an impairment loss, if any, is recognized for the difference between the implied fair value and the carrying value of the reporting unit's goodwill. The annual impairment testing performed on May 1, 2021, indicated that all reporting units with remaining goodwill had a fair value substantially in excess of its carrying value. No goodwill impairment charges were recognized during the year ended July 31, 2021. Other Intangible and Long-Lived Assets — Intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives to reflect the pattern of economic benefits consumed. Intangible assets with indefinite lives as well as goodwill are not subject to amortization. These assets are assessed for impairment on an annual basis or more frequently if events or changes in circumstances have occurred that indicate the asset may not be recoverable or that the remaining estimated useful life may warrant revision. In addition, the Company performs qualitative assessments on a quarterly basis of significant events and circumstances, such as historical and current results, assumptions regarding future performance, and strategic initiatives and overall economic factors. The Company evaluates indefinite-lived intangible assets for impairment by comparing the estimated fair value of the asset to the carrying value. Fair value is estimated using the income approach based upon current sales projections applying the relief from royalty method. If the carrying value of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The Company evaluates long-lived assets, including finite-lived intangible assets, operating lease assets, and property, plant, and equipment, for recoverability by comparing an estimate of undiscounted future cash flows, derived from internal forecasts, over the remaining life of the primary asset to the carrying amount of the asset group. To the extent the undiscounted future cash flows attributable to the asset are less than the carrying amount, an impairment loss is recognized for the amount by which the carrying value of the asset exceeds its fair value. In fiscal 2021, long-lived and other intangible assets were analyzed for potential impairment. As a result of the analysis, no impairment charges were recorded. Refer to Note 3, "Other Intangible Assets and Long-Lived Assets" for further information regarding the impairment charges recorded in fiscal 2020. Leases — The Company accounts for leases in accordance with Accounting Standards Codification ("ASC") 842 "Leases," which was adopted on August 1, 2019 using the optional transition method. The Company determines whether an arrangement contains a lease at contract inception based on whether the arrangement provides the Company with the right to direct the use of and the right to obtain substantially all of the economic benefits from an identified asset in exchange for consideration. The Company recognizes a right-of-use ("ROU") asset and lease liability for its lease commitments with initial terms greater than one year. The initial measurement of ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the expected lease term. The ROU asset also includes any lease payments made on or before the commencement date, initial direct costs incurred, and is reduced by any lease incentives received. Some of the Company’s leases include options to extend the lease agreement, of which the exercise is at the Company’s sole discretion. The majority of renewal options are not included in the calculation of ROU assets and liabilities as they are not reasonably certain to be exercised. Some of the Company's lease agreements include rental payments that are adjusted periodically for inflation or the change in an index or rate. These variable lease payments are generally excluded from the initial measurement of the ROU asset and lease liability and are recognized in the period in which the obligation for those payments is incurred. The Company has lease agreements that include both lease and non-lease components, which the Company elected to account for as a single lease component. The Company determines the present value of future lease payments using its incremental borrowing rate, as the discount rate implicit within the Company’s leases generally cannot be readily determined. The incremental borrowing rate is estimated based on the sovereign credit rating for the countries in which the Company has its largest operations, adjusted for several factors, such as internal credit spread, lease terms, and other market information available at the lease commencement date. As of July 31, 2021, all leases are accounted for as operating leases, with lease expense being recognized on a straight-line basis over the lease term. Operating leases are reflected in “Operating lease assets,” “Current operating lease liabilities,” and “Long-term operating lease liabilities” in the accompanying Consolidated Balance Sheets. Operating lease expense is recognized in either cost of goods sold or selling, general, and administrative expenses in the Consolidated Statements of Income, based on the nature of the lease. ROU assets are evaluated for impairment in the same manner as long-lived assets. No impairment charges were recognized related to operating lease assets during the fiscal year ended July 31, 2021. Refer to Note 3, "Other Intangible and Long-Lived Assets" for additional information regarding the impairment charges recognized during fiscal 2020. Revenue Recognition — The majority of the Company’s revenue relates to the sale of identification solutions and workplace safety products to customers. The Company accounts for revenue in accordance with ASC Topic 606 "Revenue from Contracts with Customers," which was adopted on August 1, 2018 using the modified retrospective approach. Revenue is recognized when control of the product or service transfers to the customer in an amount that represents the consideration expected to be received in exchange for those products and services. The Company considers control to have transferred when legal title, physical possession, and the significant risks and rewards of ownership of the asset have transferred to the customer and the collection of the transaction price is reasonably assured, most of which occur upon shipment or delivery of goods to customers. Given the nature of the Company’s business, revenue recognition practices do not contain estimates that materially affect the results of operations, with the exception of estimated customer returns and credit memos. The Company records an allowance for estimated product returns and credit memos using the expected value method based on historical experience, which is recognized as a deduction from net sales at the time of sale. As of July 31, 2021 and 2020, the Company had a reserve for estimated product returns and credit memos of $5,510 and $6,295, respectively. Sales Incentives — The Company accounts for cash consideration (such as sales incentives, rebates, and cash discounts) given to its customers or resellers as a reduction of revenue. Sales incentives for the years ended July 31, 2021, 2020, and 2019 were $38,876, $38,476, and $40,811, respectively. Shipping and Handling Costs — Shipping and handling fees billed to a customer in a sale transaction are reported as net sales and the related costs incurred for shipping and handling are reported in cost of goods sold. Advertising Costs — Advertising costs are expensed as incurred. Advertising expense for the years ended July 31, 2021, 2020, and 2019 was $54,370, $63,482, and $62,454, respectively. Stock-Based Compensation — The Company measures and recognizes the compensation expense for all share-based awards made to employees and directors based on estimated grant-date fair values. The Black-Scholes option valuation model is used to determine the fair value of stock option awards on the date of grant. The Company recognizes the compensation cost, net of estimated forfeitures, of all share-based awards on a straight-line basis over the vesting period of the award. If it is determined that it is unlikely the award will vest, the expense recognized to date for the award is reversed in the period in which this is evident and the remaining expense is not recorded. The Black-Scholes model requires the use of assumptions which determine the fair value of stock-based awards. The Company uses historical data regarding stock option exercise behaviors to estimate the expected term of options granted based on the period of time that options granted are expected to be outstanding. Expected volatilities are based on the historical volatility of the Company’s stock. The expected dividend yield is based on the Company’s historical dividend payments and historical yield. The risk-free interest rate is based on the U.S. Treasury yield curve in effect on the grant date for the length of time corresponding to the expected term of the option. The market value is calculated as the average of the high and the low stock price on the date of the grant. Refer to No te 7, “Stockholders' Equity” for more information regarding the Company’s incentive stock plans. Research and Development — Amounts expended for research and development are expensed as incurred. Other Comprehensive Income — Other comprehensive income consists of net unrealized gains and losses from cash flow hedges, the unamortized gain on defined-benefit pension plans net of their related tax effects, and foreign currency translation adjustments, which includes the impact of foreign currency translations and the settlements of net investment hedges. Foreign Currency Translation — The assets and liabilities of subsidiaries whose functional currency is a currency other than the U.S. dollar are translated into United States dollars at end of period rates of exchange, and income and expense accounts are translated at the average rates of exchange for the period. Resulting foreign currency translation adjustments are included in other comprehensive income. Income Taxes — The Company accounts for income taxes under the asset and liability method in accordance with ASC 740 "Income Taxes." Under this method, deferred income tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial reporting and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using the currently enacted tax laws and rates applicable to the periods in which the differences are expected to be realized or settled. Valuation allowances are established when it is estimated that it is more likely than not that the tax benefit of the deferred tax asset will not be realized. The Company recognizes the benefit of income tax positions only if those positions are more likely than not to be sustained upon examination by the tax authority. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. Fair Value of Financial Instruments — The Company believes that the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts payable, and other current liabilities) approximate fair value due to the short-term nature of these instruments. Refer to Note 6, "Debt" for more information regarding the fair value of long-term debt and Note 13, "Fair Value Measurements" for information regarding fair value measurements. Foreign Currency Hedging — The objective of the Company’s foreign currency exchange risk management is to minimize the impact of currency movements on non-functional currency transactions and minimize the foreign currency translation impact on the Company’s foreign operations. While the Company’s risk management objectives and strategies are driven from an economic perspective, the Company attempts, where possible and practical, to ensure that the hedging strategies it engages in qualify for hedge accounting and result in accounting treatment where the earnings effect of the hedging instrument provides substantial offset (in the same period) to the income effect of the hedged item. The Company recognizes derivative instruments as either assets or liabilities in the accompanying Consolidated Balance Sheets at fair value. Gains and losses resulting from changes in fair value of the derivatives designated as hedges are recorded as a component of Accumulated Other Comprehensive Income ("AOCI") in the accompanying Consolidated Balance Sheets and in the Consolidated Statements of Comprehensive Income and are reclassified into the same income statement line item in the period or periods during which the hedged transaction affects income. Refer to Note 14, "Derivatives and Hedging Activities" for more information regarding the Company’s derivative instruments and hedging activities. New Accounting Standards Adopted Standards In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which changes the impairment model for most financial instruments. Prior guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflected losses once the losses were probable. Under ASU 2016-13, the Company is required to use a current expected credit loss model ("CECL") that immediately recognizes an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of this update, including trade receivables. The Company adopted ASU 2016-13 effective August 1, 2020, which did not have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, "Goodwill and Other, Simplifying the Test for Goodwill Impairment." This guidance removes Step 2 of the goodwill impairment test, which required a hypothetical purchase price allocation. A goodwill impairment is now the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. The Company adopted ASC 2017-04 effective August 1, 2020. This guidance only impacts the Company's consolidated financial statements if there is a future impairment of goodwill. Standards not yet adopted In December 2019, the FASB issued ASU 2019-12, "Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740)." The new guidance removes certain exceptions to the general principles in ASC 740 such as recognizing deferred taxes for equity investments, the incremental approach to performing intraperiod tax allocation and calculating income taxes in interim periods. The standard also simplifies accounting for income taxes under U.S. GAAP by clarifying and amending existing guidance, including the recognition of deferred taxes for goodwill, the allocation of taxes to members of a consolidated group and requiring that an entity reflect the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. This guidance is effective for annual periods beginning after Dec ember 15, 2020, and interim periods thereafter. Early adoption is permitted. The Company does not expect a material impact to the financial statements or disclosures from the adoption of this standard. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." Subject to meeting certain criteria, the new guidance provides optional expedients and exceptions to applying contract modification accounting under existing U.S. GAAP, to address the expected phase out of the London Inter-bank Offered Rate ("LIBOR") by the end of 2021. This guidance was effective upon issuance and allows application to contract changes as early as January 1, 2020. Some of the Company's contracts with respect to its borrowing agreements already contain comparable alternative reference rates that would automatically take effect upon the phasing out of LIBOR. The Company does not expect a material impact to the financial statements or disclosures from the adoption of this standard.

Debt Disclosure [Abstract]
Long-Term Obligations	Debt On August 1, 2019, the Company and certain of its subsidiaries entered into an unsecured $200 million multi-currency revolving loan agreement with a group of five banks. Under this revolving loan agreement, the Company has the option to select either a Eurocurrency rate loan that bears interest at the LIBOR rate plus a margin based on the Company's consolidated net leverage ratio or a base interest rate (based upon the higher of the federal funds rate plus 0.5%, the prime rate of the Bank of Montreal plus a margin based on the Company’s consolidated net leverage ratio, or the Eurocurrency base rate at the LIBOR rate plus a margin based on the Company’s consolidated net leverage ratio plus 1%). At the Company's option, and subject to cer tain conditions, the available amount under the revolving loan agreement may be increased from $200 million to $400 million. In June 2021, the Company drew down $75.0 million from its revolving loan agreement to fund a portion of the purchase price of the acquisition of Code. Prior to July 31, 2021, the Company repaid $37.0 million of the borrowing with cash on hand. During the year ended July 31, 2021, the maximum amount outstanding on the revolving loan agreement was $75.0 million. As of July 31, 2021, the outstanding balance on the credit facility was $38.0 million and there was $159.1 million available for future borrowing under the credit facility, which can be increased to $359.1 million at the Company's option, subject to certain conditions. The revolving loan agreement has a final maturity date of August 1, 2024. The Company’s revolving loan agreement requires it to maintain certain financial covenants, including a ratio of debt to the trailing twelve months EBITDA, as defined in the agreement, of not more than a 3.5 to 1.0 ratio (leverage ratio) and the trailing twelve months EBITDA to interest expense of not less than a 3.0 to 1.0 ratio (interest expense coverage ratio). As of July 31, 2021, the Company was in compliance with these financial covenants, with a ratio of debt to EBITDA, as defined by the agreements, equal to 0.2 to 1.0 and the interest expense coverage ratio equal to 480.6 to 1.0. As of July 31, 2021, borrowings on the revolving loan agreement were as follows: July 31, 2021 Interest Rate USD-denominated borrowing on revolving loan agreement $ 38,000 0.84 % Due to the variable interest rate pricing of the Company's revolving debt, it is determined that the carrying value of the debt equals the fair value of the debt. The Company had outstanding letters of credit of $2,901 and $3,116 at July 31, 2021 and 2020, respectively.

Statement of Comprehensive Income [Abstract]
Comprehensive Income (Loss) Note [Text Block]	Other Comprehensive Loss Other comprehensive loss consists of foreign currency translation adjustments which includes net investment hedges, unrealized gains and losses from cash flow hedges, and the unamortized gain on post-retirement plans, net of their related tax effects. The following table illustrates the changes in the balances of each component of accumulated other comprehensive loss, net of tax, for the periods presented: Unrealized gain (loss) on cash flow hedges Unamortized gain on postretirement plans Foreign currency translation adjustments Accumulated other comprehensive loss Ending balance, July 31, 2019 $ 707 $ 2,800 $ (74,761) $ (71,254) Other comprehensive (loss) income before reclassification (447) (332) 6,303 5,524 Amounts reclassified from accumulated other comprehensive loss (460) (287) — (747) Ending balance, July 31, 2020 $ (200) $ 2,181 $ (68,458) $ (66,477) Other comprehensive income (loss) before reclassification 1,228 (5) 9,888 11,111 Amounts reclassified from accumulated other comprehensive loss (299) (288) — (587) Ending balance, July 31, 2021 $ 729 $ 1,888 $ (58,570) $ (55,953) The decrease in accumulated other comprehensive loss as of July 31, 2021, compared to July 31, 2020, was primarily due to the depreciation of the U.S. dollar against certain other currencies during the fiscal year. Of the amounts reclassified from accumulated other comprehensive loss during the years ended July 31, 2021 and 2020, unrealized gains on cash flow hedges were reclassified into "Cost of goods sold" and net unamortized gains on post-retirement plans were reclassified into "Investment and other income" on the Consolidated Statements of Income.

Revenue Recognition

Revenue Recognition	12 Months Ended

Revenue Recognition [Abstract]
Revenue from Contract with Customer	Revenue Recognition The Company recognizes revenue when control of the product or service transfers to the customer at an amount that represents the consideration expected to be received in exchange for those products and services. Nature of Products The Company’s revenues are primarily from the sale of identification solutions and workplace safety products that are shipped and billed to customers. All revenue is from contracts with customers and is included in “Net sales” on the Consolidated Statements of Income. See Note 10 “Segment Information” for the Company’s disaggregated revenue disclosure. Performance Obligations The Company’s contracts with customers consist of purchase orders, which in some cases are governed by master supply or distributor agreements. For each contract, the Company considers the commitment to transfer tangible products, which are generally capable of being distinct, to be separate performance obligations. The majority of the Company's revenue is earned and recognized at a point in time through ship-and-bill performance obligations where the customer typically obtains control of the product upon shipment or delivery, depending on freight terms. The Company considers control to have transferred if legal title, physical possession, and the significant risks and rewards of ownership of the asset have transferred to the customer and the Company has a present right to payment. In almost all cases, control transfers once a product is shipped or delivered, as this is when the customer is able to direct and obtain substantially all of the remaining benefits associated with use of the asset. Transaction Price and Variable Consideration Revenue is measured as the amount of consideration the Company expects to be entitled to in exchange for the transfer of product to a customer. The transaction price is generally the price stated in the contract specific for each item sold, adjusted for all applicable variable considerations. Variable consideration generally include discounts, returns, credits, rebates, or other allowances that reduce the transaction price. Certain discounts and price assurances are fixed and known at the time of sale. The Company estimates the amount of variable consideration and reduces the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The expected value method is used to estimate expected returns and allowances based on historical experience. The most likely amount method is used to estimate customer rebates, which are offered retrospectively and typically defined in the master supply or distributor agreement. Payment Terms While the Company’s standard payment terms are net 30 days, the specific payment terms and conditions in its contracts with customers vary by type and location of the customer. Cash discounts may be offered to certain customers. The Company has payment terms in its contracts with customers of less than one year and has elected the practical expedient applicable to such contracts and does not consider the time value of money. Warranties The Company offers standard warranty coverage on substantially all products which provides the customer with assurance that the product will function as intended. This standard warranty coverage is accounted for as an assurance warranty and is not considered to be a separate performance obligation. The Company records a liability for product warranty obligations at the time of sale based on historical warranty experience that is included in cost of goods sold. The Company also offers extended warranty coverage for certain products, which it accounts for as service warranties. In most cases, the extended service warranty is included in the sales price of the product and is not sold separately. The Company considers the extended service warranty to be a separate performance obligation and allocates a portion of the transaction price to the service warranty based on the estimated stand-alone selling price. At the time of sale, the extended warranty transaction price is recorded as deferred revenue on the Consolidated Balance Sheets and is recognized on a straight-line basis over the life of the service warranty period. The deferred revenue is considered a contract liability as the Company has a right to payment at the time the product with the related extended service warranty is shipped or delivered and therefore, payment is received in advance of the Company's performance. Contract Balances The balance of contract liabilities associated with service warranty performance obligations was $2,519 and $2,559 as of July 31, 2021 and 2020, respectively. This also represents the amount of unsatisfied performance obligations related to contracts that extend beyond one year. The current portion and non-current portion of contract liabilities are included in “Other current liabilities” and “Other liabilities," respectively, on the accompanying Consolidated Balance Sheets. During the fiscal year ended July 31, 2021, the Company recognized revenue of $1,175 that was included in the contract liability balance at the beginning of the period from the amortization of extended service warranties. Of the contract liability balance outstanding at July 31, 2021, the Company expects to recognize 41% by the end of fiscal 2022, an additional 28% by the end of fiscal 2023, and the balance thereafter. Costs of Obtaining a Contract The Company expenses incremental direct costs of obtaining a contract (e.g., sales commissions) when incurred because the amortization period is generally twelve months or less. Contract costs are included in "Selling, general and administrative expense" on the Consolidated Statements of Income.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In accordance with fair value accounting guidance, the Company determines fair value based on the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The inputs used to measure fair value are classified into the following hierarchy: Level 1 — Unadjusted quoted prices in active markets for identical instruments that are accessible as of the reporting date. Level 2 — Other significant pricing inputs that are either directly or indirectly observable. Level 3 — Significant unobservable pricing inputs, which result in the use of management's own assumptions. The following table summarizes the Company's financial assets and liabilities that were accounted for at fair value on a recurring basis at July 31, 2021 and July 31, 2020, according to the valuation techniques the Company used to determine their fair values. July 31, 2021 July 31, 2020 Fair Value Hierarchy Assets: Trading securities $ 20,135 $ 18,606 Level 1 Foreign exchange contracts 150 594 Level 2 Liabilities: Foreign exchange contracts $ 51 $ 777 Level 2 The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Trading securities : The Company’s deferred compensation investments consist of investments in mutual funds, which are included in "Other assets" on the accompanying Consolidated Balance Sheets. These investments were classified as Level 1 as the shares of these investments trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. Foreign exchange contracts : The Company’s foreign exchange contracts were classified as Level 2 as the fair value was based on the present value of the future cash flows using external models that use observable inputs, such as interest rates, yield curves and foreign exchange rates. See Note 14 , “Derivatives and Hedging Activities,” for additional information. There have been no transfers of assets or liabilities between the fair value hierarchy levels, outlined above, during the fiscal years ended July 31, 2021 and July 31, 2020. See Note 6 for information regarding the fair value of the Company's long-term debt.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company utilizes forward foreign exchange currency contracts to reduce the exchange rate risk of specific foreign currency denominated transactions. These contracts typically require the exchange of a foreign currency for U.S. dollars at a fixed rate at a future date, with maturities of less than 18 months, which qualify as cash flow hedges or net investment hedges under the accounting guidance for derivative instruments and hedging activities. The primary objective of the Company’s foreign currency exchange risk management program is to minimize the impact of currency movements due to transactions in other than the respective subsidiaries’ functional currency and to minimize the impact of currency movements on the Company’s net investment denominated in a currency other than the U.S. dollar. To achieve this objective, the Company hedges a portion of known exposures using forward foreign exchange contracts. Main foreign currency exposures are related to transactions denominated in the British Pound, Euro, Canadian dollar, Australian dollar, Mexican Peso, Chinese Yuan, Malaysian Ringgit and Singapore dollar. Generally, these risk management transactions will involve the use of foreign currency derivatives to minimize the impact of currency movements on non-functional currency transactions. The U.S. dollar equivalent notional amounts of outstanding forward exchange contracts were as follows as of July 31, 2021 and 2020: July 31, 2021 July 31, 2020 Designated as cash flow hedges $ 30,724 $ 24,600 Non-designated hedges 3,580 3,107 Total foreign exchange contracts $ 34,304 $ 27,707 Cash Flow Hedges The Company has designated a portion of its forward foreign exchange contracts as cash flow hedges and recorded these contracts at fair value on the accompanying Consolidated Balance Sheets.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jul. 31, 2021
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations — Brady Corporation is a global manufacturer and supplier of identification solutions and workplace safety products that identify and protect premises, products and people. The ability to provide customers with a broad range of proprietary, customized, and diverse products for use in various applications, along with a commitment to quality and service, a global footprint, and multiple sales channels, have made Brady a world leader in many of its markets.
Principles of Consolidation	Principles of Consolidation — The accompanying consolidated financial statements include the accounts of Brady Corporation and its wholly owned subsidiaries. All intercompany accounts and transactions between consolidated subsidiaries have been eliminated in consolidation.
Use of Estimates	Use of Estimates — The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"), which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Acquisitions	Acquisitions — The Company recognizes assets acquired, liabilities assumed, contractual contingencies and contingent consideration at their fair value on the acquisition date. The operating results of the acquired companies are included in the Company’s consolidated financial statements from the date of acquisition. Acquisition-related costs are expensed as incurred and changes in deferred tax asset valuation allowances and income tax uncertainties after the measurement period are recorded in Provision for Income Taxes.
Cash Equivalents	Cash Equivalents — The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents.
Concentration of Credit Risk	Concentration of Credit Risk — The Company places temporary cash investments with global financial institutions of high credit quality. The Company performs periodic evaluations of the relative credit standing of its financial institutions and limits the amount of credit exposure with any one financial institution. In addition, the Company has a broad customer base representing many diverse industries throughout the globe. Consequently, no significant concentration of credit risk is considered to exist.
Accounts Receivables	Accounts Receivables — The Company's policy for estimating the allowance for credit losses on accounts receivables considers several factors including historical loss experience, the age of delinquent receivable balances due, and economic conditions. Specific customer reserves are made during review of significant outstanding balances due, in which customer creditworthiness and current economic trends may indicate that it is probable the receivable will not be recovered. Accounts receivables are written off after collection efforts occur and the receivable is deemed uncollectible. Adjustments to the allowance for credit losses are recorded in SG&A expense.
Equity Method Investment	Equity Method Investment — The equity method of accounting is applied to investments in which the Company has an ownership interest of between 20% and 50%. The Company evaluates its equity method investments each reporting period for evidence of a loss in value that is other than a temporary decline. Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain an earnings capacity that would justify the carrying amount of the investment. The Company performed this analysis and concluded that its investment in React Mobile, Inc. was other-than-temporarily impaired and recognized an impairment charge of $4,994 for the year ended July 31, 2021.
Inventories	Inventories — Inventories are stated at the lower of cost or net realizable value and include material, labor, and overhead. Cost has been determined using the last-in, first-out (“LIFO”) method for certain inventories in the U.S. (12.5% of total inventories at July 31, 2021, and 14.7% of total inventories at July 31, 2020) and the first-in, first-out (“FIFO”) or average cost methods for all other inventories. Had all inventories been accounted for on a FIFO basis instead of on a LIFO basis, the carrying value of inventories would have increased by $7,707 and $7,195 as of July 31, 2021 and 2020, respectively. Inventories consist of the following as of July 31: 2021 2020 Finished products $ 87,489 $ 85,547 Work-in-process 20,189 24,044 Raw materials and supplies 28,429 26,071 Total inventories $ 136,107 $ 135,662
Property, Plant and Equipment	Property, Plant and Equipment — Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed primarily on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective asset. The estimated useful lives range from 3 to 33 years as shown below. Property, plant and equipment consist of the following as of July 31: Range of Useful Lives 2021 2020 Land $ 8,201 $ 9,960 Buildings and improvements 10 to 33 Years 108,801 105,129 Machinery and equipment 3 to 10 Years 276,994 267,795 Construction in progress 4,991 8,432 Property, plant and equipment—gross 398,987 391,316 Accumulated depreciation (277,246) (276,248) Property, plant and equipment—net $ 121,741 $ 115,068
Goodwill, Other Intangible and Long-Lived Assets	Goodwill — The Company evaluates the carrying amount of goodwill annually or more frequently if events or changes in circumstances have occurred that indicate the goodwill might be impaired. The Company completes impairment reviews for its reporting units using a fair-value method based on management's judgments and assumptions. When performing its annual impairment assessment, the Company evaluates the recoverability of goodwill assigned to each of its reporting units by comparing the estimated fair value of the respective reporting unit to the carrying value, including goodwill. The Company estimates fair value utilizing the income approach and the market approach. The income approach requires management to make a number of assumptions and estimates for each reporting unit, including projected future operating results, economic projections, anticipated future cash flows, working capital levels, income tax rates, and a weighted-average cost of capital reflecting the specific risk profile of the respective reporting unit. The market approach estimates fair value using performance multiples of comparable publicly-traded compa nies. In the event the fair value of a reporting unit is less than the carrying value, including goodwill, an impairment loss, if any, is recognized for the difference between the implied fair value and the carrying value of the reporting unit's goodwill. The annual impairment testing performed on May 1, 2021, indicated that all reporting units with remaining goodwill had a fair value substantially in excess of its carrying value. No goodwill impairment charges were recognized during the year ended July 31, 2021. Other Intangible and Long-Lived Assets — Intangible assets with definite lives are amortized on a straight-line basis over their estimated useful lives to reflect the pattern of economic benefits consumed. Intangible assets with indefinite lives as well as goodwill are not subject to amortization. These assets are assessed for impairment on an annual basis or more frequently if events or changes in circumstances have occurred that indicate the asset may not be recoverable or that the remaining estimated useful life may warrant revision. In addition, the Company performs qualitative assessments on a quarterly basis of significant events and circumstances, such as historical and current results, assumptions regarding future performance, and strategic initiatives and overall economic factors. The Company evaluates indefinite-lived intangible assets for impairment by comparing the estimated fair value of the asset to the carrying value. Fair value is estimated using the income approach based upon current sales projections applying the relief from royalty method. If the carrying value of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The Company evaluates long-lived assets, including finite-lived intangible assets, operating lease assets, and property, plant, and equipment, for recoverability by comparing an estimate of undiscounted future cash flows, derived from internal forecasts, over the remaining life of the primary asset to the carrying amount of the asset group. To the extent the undiscounted future cash flows attributable to the asset are less than the carrying amount, an impairment loss is recognized for the amount by which the carrying value of the asset exceeds its fair value. In fiscal 2021, long-lived and other intangible assets were analyzed for potential impairment. As a result of the analysis, no impairment charges were recorded. Refer to Note 3, "Other Intangible Assets and Long-Lived Assets" for further information regarding the impairment charges recorded in fiscal 2020.
Leases	Leases — The Company accounts for leases in accordance with Accounting Standards Codification ("ASC") 842 "Leases," which was adopted on August 1, 2019 using the optional transition method. The Company determines whether an arrangement contains a lease at contract inception based on whether the arrangement provides the Company with the right to direct the use of and the right to obtain substantially all of the economic benefits from an identified asset in exchange for consideration. The Company recognizes a right-of-use ("ROU") asset and lease liability for its lease commitments with initial terms greater than one year. The initial measurement of ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the expected lease term. The ROU asset also includes any lease payments made on or before the commencement date, initial direct costs incurred, and is reduced by any lease incentives received. Some of the Company’s leases include options to extend the lease agreement, of which the exercise is at the Company’s sole discretion. The majority of renewal options are not included in the calculation of ROU assets and liabilities as they are not reasonably certain to be exercised. Some of the Company's lease agreements include rental payments that are adjusted periodically for inflation or the change in an index or rate. These variable lease payments are generally excluded from the initial measurement of the ROU asset and lease liability and are recognized in the period in which the obligation for those payments is incurred. The Company has lease agreements that include both lease and non-lease components, which the Company elected to account for as a single lease component. The Company determines the present value of future lease payments using its incremental borrowing rate, as the discount rate implicit within the Company’s leases generally cannot be readily determined. The incremental borrowing rate is estimated based on the sovereign credit rating for the countries in which the Company has its largest operations, adjusted for several factors, such as internal credit spread, lease terms, and other market information available at the lease commencement date. As of July 31, 2021, all leases are accounted for as operating leases, with lease expense being recognized on a straight-line basis over the lease term. Operating leases are reflected in “Operating lease assets,” “Current operating lease liabilities,” and “Long-term operating lease liabilities” in the accompanying Consolidated Balance Sheets. Operating lease expense is recognized in either cost of goods sold or selling, general, and administrative expenses in the Consolidated Statements of Income, based on the nature of the lease. ROU assets are evaluated for impairment in the same manner as long-lived assets. No impairment charges were recognized related to operating lease assets during the fiscal year ended July 31, 2021. Refer to Note 3, "Other Intangible and Long-Lived Assets" for additional information regarding the impairment charges recognized during fiscal 2020.
Revenue Recongition	Revenue Recognition — The majority of the Company’s revenue relates to the sale of identification solutions and workplace safety products to customers. The Company accounts for revenue in accordance with ASC Topic 606 "Revenue from Contracts with Customers," which was adopted on August 1, 2018 using the modified retrospective approach.
Advertising Costs	Advertising Costs — Advertising costs are expensed as incurred. Advertising expense for the years ended July 31, 2021, 2020, and 2019 was $54,370, $63,482, and $62,454, respectively.
Stock-Based Compensation	Stock-Based Compensation — The Company measures and recognizes the compensation expense for all share-based awards made to employees and directors based on estimated grant-date fair values. The Black-Scholes option valuation model is used to determine the fair value of stock option awards on the date of grant. The Company recognizes the compensation cost, net of estimated forfeitures, of all share-based awards on a straight-line basis over the vesting period of the award. If it is determined that it is unlikely the award will vest, the expense recognized to date for the award is reversed in the period in which this is evident and the remaining expense is not recorded. The Black-Scholes model requires the use of assumptions which determine the fair value of stock-based awards. The Company uses historical data regarding stock option exercise behaviors to estimate the expected term of options granted based on the period of time that options granted are expected to be outstanding. Expected volatilities are based on the historical volatility of the Company’s stock. The expected dividend yield is based on the Company’s historical dividend payments and historical yield. The risk-free interest rate is based on the U.S. Treasury yield curve in effect on the grant date for the length of time corresponding to the expected term of the option. The market value is calculated as the average of the high and the low stock price on the date of the grant. Refer to No te 7, “Stockholders' Equity” for more information regarding the Company’s incentive stock plans.
Research and Development	Research and Development — Amounts expended for research and development are expensed as incurred.
Other Comprehensive Income	Other Comprehensive Income —
Foreign Currency Translation	Foreign Currency Translation — The assets and liabilities of subsidiaries whose functional currency is a currency other than the U.S. dollar are translated into United States dollars at end of period rates of exchange, and income and expense accounts are translated at the average rates of exchange for the period. Resulting foreign currency translation adjustments are included in other comprehensive income.
Income Taxes	Income Taxes — The Company accounts for income taxes under the asset and liability method in accordance with ASC 740 "Income Taxes." Under this method, deferred income tax assets and liabilities are recognized for the expected future tax consequences attributable to differences between the financial reporting and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using the currently enacted tax laws and rates applicable to the periods in which the differences are expected to be realized or settled. Valuation allowances are established when it is estimated that it is more likely than not that the tax benefit of the deferred tax asset will not be realized. The Company recognizes the benefit of income tax positions only if those positions are more likely than not to be sustained upon examination by the tax authority. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs.
Fair Value of Financial Instruments	Fair Value of Financial Instruments — The Company believes that the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts payable, and other current liabilities) approximate fair value due to the short-term nature of these instruments. Refer to Note 6, "Debt" for more information regarding the fair value of long-term debt and Note 13, "Fair Value Measurements" for information regarding fair value measurements.
Foreign Currency Hedging	Foreign Currency Hedging — The objective of the Company’s foreign currency exchange risk management is to minimize the impact of currency movements on non-functional currency transactions and minimize the foreign currency translation impact on the Company’s foreign operations. While the Company’s risk management objectives and strategies are driven from an economic perspective, the Company attempts, where possible and practical, to ensure that the hedging strategies it engages in qualify for hedge accounting and result in accounting treatment where the earnings effect of the hedging instrument provides substantial offset (in the same period) to the income effect of the hedged item. The Company recognizes derivative instruments as either assets or liabilities in the accompanying Consolidated Balance Sheets at fair value. Gains and losses resulting from changes in fair value of the derivatives designated as hedges are recorded as a component of Accumulated Other Comprehensive Income ("AOCI") in the accompanying Consolidated Balance Sheets and in the Consolidated Statements of Comprehensive Income and are reclassified into the same income statement line item in the period or periods during which the hedged transaction affects income. Refer to Note 14, "Derivatives and Hedging Activities" for more information regarding the Company’s derivative instruments and hedging activities.
New Accounting Standards	New Accounting Standards Adopted Standards In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which changes the impairment model for most financial instruments. Prior guidance required the recognition of credit losses based on an incurred loss impairment methodology that reflected losses once the losses were probable. Under ASU 2016-13, the Company is required to use a current expected credit loss model ("CECL") that immediately recognizes an estimate of credit losses that are expected to occur over the life of the financial instruments that are in the scope of this update, including trade receivables. The Company adopted ASU 2016-13 effective August 1, 2020, which did not have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, "Goodwill and Other, Simplifying the Test for Goodwill Impairment." This guidance removes Step 2 of the goodwill impairment test, which required a hypothetical purchase price allocation. A goodwill impairment is now the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. The Company adopted ASC 2017-04 effective August 1, 2020. This guidance only impacts the Company's consolidated financial statements if there is a future impairment of goodwill. Standards not yet adopted In December 2019, the FASB issued ASU 2019-12, "Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740)." The new guidance removes certain exceptions to the general principles in ASC 740 such as recognizing deferred taxes for equity investments, the incremental approach to performing intraperiod tax allocation and calculating income taxes in interim periods. The standard also simplifies accounting for income taxes under U.S. GAAP by clarifying and amending existing guidance, including the recognition of deferred taxes for goodwill, the allocation of taxes to members of a consolidated group and requiring that an entity reflect the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. This guidance is effective for annual periods beginning after Dec ember 15, 2020, and interim periods thereafter. Early adoption is permitted. The Company does not expect a material impact to the financial statements or disclosures from the adoption of this standard. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." Subject to meeting certain criteria, the new guidance provides optional expedients and exceptions to applying contract modification accounting under existing U.S. GAAP, to address the expected phase out of the London Inter-bank Offered Rate ("LIBOR") by the end of 2021. This guidance was effective upon issuance and allows application to contract changes as early as January 1, 2020. Some of the Company's contracts with respect to its borrowing agreements already contain comparable alternative reference rates that would automatically take effect upon the phasing out of LIBOR. The Company does not expect a material impact to the financial statements or disclosures from the adoption of this standard.
