Organization Consolidation And Presentation Of Financial Statements [Abstract]
Operations and Summary of Significant Accounting Policies	Note 1. Operations and summary of significant accounting policies Basis of presentation The Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Woodward, Inc. and its subsidiaries (collectively “Woodward” or “the Company”). Dollar amounts contained in these Consolidated Financial Statements are in thousands, except per share amounts. Nature of operations Woodward is an independent designer, manufacturer, and service provider of energy control and optimization solutions. Woodward designs, produces and services reliable, efficient, low-emission, and high-performance energy control products for diverse applications in challenging environments. Woodward has significant production and assembly facilities primarily in the United States, Europe and Asia, and promotes its products and services through its worldwide locations. Woodward’s strategic focus is providing energy control and optimization solutions for the aerospace and industrial markets. The precise and efficient control of energy, including motion, fluid, combustion and electrical energy, is a growing requirement in the markets Woodward serves. Woodward’s customers look to it to optimize the efficiency, emissions and operation of power equipment in both commercial and defense operations. Woodward’s core technologies leverage well across its markets and customer applications, enabling it to develop and integrate cost-effective and state-of-the-art fuel, combustion, fluid, actuation and electronic systems. Woodward focuses its solutions and services primarily on serving original equipment manufacturers (“OEMs”) and equipment packagers, partnering with them to bring superior component and system solutions to their demanding applications. Woodward also provides aftermarket repair, maintenance, replacement and other service support for its installed products. Woodward’s components and integrated systems optimize performance of commercial aircraft, defense aircraft, military ground vehicles and other equipment, gas and steam turbines, industrial diesel, gas, biodiesel and dual-fuel reciprocating engines, and electrical power systems. Woodward’s innovative motion, fluid, combustion and electrical energy control systems help its customers offer more cost-effective, cleaner, and more reliable equipment. COVID-19 Pandemic When combined with the various measures enacted by governments and private organizations to contain COVID-19 or slow its spread, the pandemic has adversely impacted global activity and contributed to volatility in financial markets; and the Company has likewise been significantly impacted by the global COVID-19 pandemic. The COVID-19 pandemic could continue to have a material adverse impact on economic and market conditions and presents uncertainty and risk with respect to the Company and its performance and financial results, including estimates and assumptions used by management for the reported amount of assets and liabilities. Summary of significant accounting policies Principles of consolidation: These Consolidated Financial Statements are prepared in accordance with U.S. GAAP and include the accounts of Woodward and its wholly and majority-owned subsidiaries. Transactions within and between these companies are eliminated. Use of estimates: The preparation of the Consolidated Financial Statements requires management to make use of estimates and assumptions that affect the reported amount of assets and liabilities, at the date of the financial statements and the reported revenues and expenses recognized during the reporting period, and certain financial statement disclosures. Significant estimates include allowances for uncollectible amounts, net realizable value of inventories, customer rebates earned, useful lives of property and identifiable intangible assets, the evaluation of impairments of property, identifiable intangible assets and goodwill, the provision for income tax and related valuation reserves, the valuation of assets and liabilities acquired in business combinations, assumptions used in the determination of the funded status and annual expense of pension and postretirement employee benefit plans, the valuation of stock compensation instruments granted to employees, and contingencies. Actual results could differ from those estimates. Foreign currency exchange rates: The assets and liabilities of substantially all subsidiaries outside the United States are translated at fiscal year-end rates of exchange, and earnings and cash flow statements are translated at weighted-average rates of exchange. The exchange rate in effect at the time of the cash flow is used for significant or infrequent cash flows, such as payments for a business acquisition, for which the use of weighted-average rates of exchange would result in a substantially different cash flow. Translation adjustments are accumulated with other comprehensive (losses) earnings as a separate component of stockholders’ equity and are presented net of tax effects in the Consolidated Statements of Stockholders’ Equity. The effects of changes in foreign currency exchange rates on loans between consolidated subsidiaries that are considered permanent in nature are also accumulated with other comprehensive earnings, net of tax. The Company is exposed to market risks related to fluctuations in foreign currency exchange rates because some sales transactions, and certain assets and liabilities of its domestic and foreign subsidiaries, are denominated in foreign currencies. Selling, general, and administrative expenses include a net foreign currency loss of $1,986 in fiscal year 2021, a net foreign currency gain of $194 in fiscal year 2020, and a net foreign currency loss of $1,018 in fiscal year 2019. Revenue recognition: Revenue is recognized on contracts with customers for arrangements in which quantities and pricing are fixed and/or determinable and are generally based on customer purchase orders, often within the framework of a long-term supply arrangement with the customer. Woodward has determined that it is the principal in its sales transactions, as Woodward is primarily responsible for fulfilling the promised performance obligations, has discretion to establish the selling price, and generally assumes the inventory risk. Woodward recognizes revenue for performance obligations within a customer contract when control of the associated product or service is transferred to the customer. Some of Woodward’s contracts with customers contain a single performance obligation, while other contracts contain multiple performance obligations. Each product within a contract generally represents a separate performance obligation as Woodward does not provide significant installation and integration services, the products do not customize each other, and the products can function independently of each other. A contract's transaction price is allocated to each performance obligation and recognized as revenue when, or as, the customer obtains control of the associated product or service. When there are multiple performance obligations within a contract, Woodward generally uses the observable standalone sales price for each distinct product or service within the contract to allocate the transaction price to the distinct products or services. In instances when a standalone sales price for each product or service is not observable within the contract, Woodward allocates the transaction price to each performance obligation using an estimate of the standalone selling price for each product or service, which is generally based on incurred costs plus a reasonable margin, for each distinct product or service in the contract. When determining the transaction price of each contract, Woodward considers contractual consideration payable by the customer and variable consideration that may affect the total transaction price. Variable consideration, consisting of early payment discounts, rebates and other sources of price variability, are included in the estimated transaction price based on both customer-specific information as well as historical experience. Customers sometimes trade in used products in exchange for new or refurbished products. In addition, Woodward’s customers sometimes provide inventory to Woodward which will be integrated into final products sold to those customers. Woodward obtains control of these exchanged products and customer provided inventory, and therefore, both are forms of noncash consideration. Noncash consideration paid by customers on overall sales transactions is additive to the transaction price. Woodward’s net sales and cost of goods sold include the value of such noncash consideration for the same amount, with no resulting impact to earnings before income taxes. Upon receipt of such inventory, Woodward recognizes an inventory asset and a contract liability. Point in time and over time revenue recognition: Control of the products generally transfers to the customer at a point in time, as the customer does not control the products as they are produced. Performance obligations are satisfied and revenue is recognized over time if: (i) the customer receives the benefits as Woodward performs work, if the customer controls the asset as it is being enhanced, or if the product being produced for the customer has no alternative use to Woodward; and (ii) Woodward has an enforceable right to payment with a profit. For products being produced for the customer that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and where the products are substantially the same and have the same pattern of transfer to the customer, revenue is recognized as a series of distinct products. As Woodward satisfies manufacturing, repair and overhaul (“MRO”) performance obligations, revenue is recognized over time, as the customer, rather than Woodward, controls the asset being enhanced. When services are provided, revenue from those services is recognized over time because control is transferred continuously to customers as Woodward performs the work. For services that are not short-term in nature, MRO, and sales of products that have no alternative use to Woodward and an enforceable right to payment with a profit, Woodward uses an actual cost input measure to determine the extent of progress towards completion of the performance obligation. For these revenue streams, revenue is recognized over time as work is performed based on the relationship between actual costs incurred to-date for each contract and the total estimated costs for such contract at completion of the performance obligation (the cost-to-cost method). Woodward has concluded that this measure of progress best depicts the transfer of assets to the customer, because incurred costs are integral to Woodward’s completion of the performance obligation under the specific customer contract and correlate directly to the transfer of control to the customer. Contract costs include labor, material and overhead. Contract cost estimates are based on various assumptions to project the outcome of future events. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the performance of subcontractors; and the availability and timing of funding from the customer. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, Woodward recognizes provisions for estimated losses on uncompleted contracts in the period in which such losses are determined. In situations where the creditworthiness of a customer becomes in doubt, Woodward ceases to recognize the over-time revenue on the associated customer contract. Occasionally, Woodward sells maintenance or service arrangements, extended warranties, or other stand ready services. Woodward recognizes revenue from such arrangements as a series of performance obligations over the time period in which the services are available to the customer. Material Rights and Costs to Fulfill a Contract : Customers sometimes pay consideration to Woodward for product engineering and development activities that do not result in the immediate transfer of distinct products or services to the customer. There is an implicit assumption that without the customer making such advance payments to Woodward, Woodward’s future sales of products or services to the customer would be at a higher selling price; therefore, such payments create a “material right” to the customer that effectively gives the customer an option to acquire future products or services, at a discount, that are dependent upon the product engineering and development. Material rights are recorded as contract liabilities and will be recognized when control of the related products or services are transferred to the customer. Woodward capitalizes costs of product engineering and development identified as material rights up to the amount of customer funding as costs to fulfill a contract because the costs incurred up to the amount of the customer funding commitment are recoverable. Due to the uncertainty of the product success and/or demand, fulfillment costs in excess of the customer funding are expensed as incurred. Woodward recognizes the deferred material rights as revenue based on a percentage of actual sales to total estimated lifetime sales of the related developed products as the customers exercise their option to acquire additional products or services at a discount. Woodward amortizes the capitalized costs to fulfill a contract as cost of goods sold proportionally to the recognition of the associated deferred material rights. Estimated total lifetime sales are reviewed at least annually and more frequently when circumstances warrant a modification to the previous estimate. Woodward does not capitalize incremental costs of obtaining a contract, as Woodward does not pay sales commissions or incur other incremental costs related to contracts with Woodward’s customers for arrangements in which quantities and pricing are fixed and/or determinable. Contract liabilities: Advance payments and billings in excess of revenue recognized represent contract liabilities and are recorded as deferred revenues when customers remit contractual cash payments in advance of Woodward satisfying performance obligations under contractual arrangements, including those with performance obligations satisfied over time. Woodward generally receives advance payments from customers related to maintenance or service arrangements, extended warranties, or other stand ready services, which it recognizes over the performance period. Contract liabilities are satisfied when revenue is recognized and the performance obligation is satisfied. Advance payments and billings in excess of revenue recognized are included in deferred revenue, which is classified as current or noncurrent based on the timing of when Woodward expects to recognize revenue. Customer payments : Woodward occasionally agrees to make payments to certain customers in order to participate in anticipated sales activity. Payments made to customers are accounted for as a reduction of revenue unless they are made in exchange for identifiable goods or services with fair values that can be reasonably estimated. Reductions in revenue associated with these customer payments are recognized immediately to the extent that the payments cannot be attributed to anticipated future sales, and are recognized in future periods to the extent that the payments relate to anticipated future sales. Such determinations are based on the facts and circumstances underlying each payment. Stock-based compensation: Compensation cost relating to stock-based payment awards made to employees and directors is recognized in the financial statements using a fair value method. Non-qualified stock option awards and restricted stock awards are issued under Woodward’s stock-based compensation plans. The cost of such awards, measured at the grant date, is based on the estimated fair value of the award. Forfeitures are estimated at the time of each grant in order to estimate the portion of the award that will ultimately vest. The estimate is based on Woodward’s historical rates of forfeitures and is updated periodically. The portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods, which is generally the vesting period of the awards. Research and development costs: Company funded expenditures related to new product development, and significant product enhancement and/or upgrade activities are expensed as incurred and are separately reported in the Consolidated Statements of Earnings Income taxes: Deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of Woodward’s assets, liabilities, and certain unrecognized gains and losses recorded in accumulated other comprehensive (losses) earnings. Woodward provides for taxes that may be payable if undistributed earnings of overseas subsidiaries were to be remitted to the United States, except for those earnings that it considers to be indefinitely invested Cash equivalents: Highly liquid investments purchased with an original maturity of three months or less are considered to be cash equivalents. Accounts receivable: Almost all of Woodward’s sales are made on credit and result in accounts receivable, which are recorded at the amount invoiced and are generally not collateralized. In the normal course of business, not all accounts receivable are collected and, therefore, an allowance for uncollectible amounts is provided equal to the amount that Woodward believes ultimately will not be collected, either from credit risk or other adjustments to the original selling price or anticipated cash discounts. In establishing the amount of the allowance related to the credit risk of accounts receivable, customer-specific information is considered related to delinquent accounts, past loss experience, bankruptcy filings, deterioration in the customer’s operating results or financial position, current and forecasted economic conditions, and other relevant factors. Bad debt losses are deducted from the allowance, and the related accounts receivable balances are written off when the receivables are deemed uncollectible. Recoveries of accounts receivable previously written off are recognized when received. The allowance associated with anticipated other adjustments to the selling price or cash discounts is also established and is included in the allowance for uncollectible amounts. In establishing this amount, both customer-specific information as well as historical experience is considered. In coordination with its customers and when terms are considered favorable to Woodward, Woodward from time-to-time transfers ownership to collect amounts due to Woodward for outstanding accounts receivable to third parties in exchange for cash. When the transfer of accounts receivable meets the criteria of Financial Accounting Standards Board (“FASB”) ASC Topic 860-10, “Transfers and Servicing,” and are without recourse, it is recognized as a sale and the accounts receivable is derecognized. Unbilled receivables (contract assets) arise when the timing of billing differs from the timing of revenue recognized, such as when contract provisions require revenue to be recognized over time rather than at a point in time. Unbilled receivables primarily relate to performance obligations satisfied over time when the cost-to-cost method is utilized and the revenue recognized exceeds the amount billed to the customer as there is not yet a right to payment in accordance with contractual terms. Unbilled receivables are recorded as a contract asset when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. Consistent with common business practice in China, Woodward’s Chinese subsidiaries accept bankers’ acceptance notes from Chinese customers in settlement of certain customer billed accounts receivable. Bankers’ acceptance notes are financial instruments issued by Chinese financial institutions as part of financing arrangements between the financial institution and a customer of the financial institution. Bankers’ acceptance notes represent a commitment by the issuing financial institution to pay a certain amount of money at a specified future maturity date to the legal owner of the bankers’ acceptance note as of the maturity date. The maturity date of bankers’ acceptance notes varies, but it is Woodward’s policy to only accept bankers’ acceptance notes with maturity dates no more than 180 days from the date of Woodward’s receipt of such draft. Woodward has elected to adopt the practical expedient to not adjust the promised amounts of consideration for the effects of a significant financing component at contract inception as the financing component associated with accepting bankers’ acceptance notes has a duration of less than one year. Woodward’s contracts with customers generally have no other financing components. For composition of accounts receivable, see Note 3, Revenue. Inventories: Inventories are valued at the lower of cost or net realizable value, with cost being determined using methods that approximate a first-in, first-out basis. Short-term investments: From time to time, certain of Woodward’s foreign subsidiaries will invest excess cash in short-term time deposits with a fixed maturity date of longer than three months but less than one year from the date of the deposit. Woodward believes that the investments are with creditworthy financial institutions. Amounts with maturities of less than 365 days are classified as “Other current assets.” Property, plant, and equipment: Property, plant, and equipment are recorded at cost and are depreciated over the estimated useful lives of the assets. Assets are generally depreciated using the straight-line method. Assets are tested for recoverability whenever events or circumstances indicate the carrying value may not be recoverable. Estimated lives over which fixed assets are generally depreciated at September 30, 2021 were as follows: Land improvements 3 – 20 years Buildings and improvements 3 – 40 years Leasehold improvements 1 – 10 years Machinery and production equipment 3 – 20 years Computer equipment and software 1 – 10 years Office furniture and equipment 3 – 10 years Other 3 – 10 years Included in computer equipment and software are Woodward’s enterprise resource planning (“ERP”) systems, which have an estimated useful life of 10 years. All other computer equipment and software is generally depreciated over three years to five years. Leases: Right-of-use (“ROU”) assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the remaining fixed lease payments over the lease term. In determining the estimated present value of lease payments, Woodward discounts the fixed lease payments using the rate implicit in the agreement or, if the implicit rate is not known, using the incremental borrowing rate. Woodward’s incremental borrowing rate is based on the information available at the lease commencement date, with consideration given to Woodward’s recent debt issuances as well as publicly available data for instruments with similar characteristics. For operating leases, lease expense is recognized over the expected lease term and classified as a cost of goods sold or selling, general and administrative expense based on the nature of the underlying leased asset. For finance leases, the ROU asset is recognized over the shorter of the useful life of the asset, consistent with Woodward’s normal depreciation policy, or the lease term, and is classified as a cost of goods sold, selling, general and administrative expense, or research and development expense, based on the nature and use of the underlying leased asset. Certain of Woodward’s operating lease agreements include variable payments that are passed through by the landlord, such as insurance, taxes, and common area maintenance, payments based on the usage of the asset, and rental payments adjusted periodically for inflation. Pass-through charges, payments due to changes in usage of the asset, and payments due to changes in indexation are included within variable rent expense and are recognized in the period in which the variable obligation for the payments was incurred. Goodwill: Woodward tests goodwill for impairment at the reporting unit level on an annual basis and more often if an event occurs or circumstances change that indicates the fair value of a reporting unit may be below its carrying amount. Based on the relevant U.S. GAAP authoritative guidance, Woodward aggregates components of a single operating segment into a reporting unit, if appropriate. The impairment test consists of comparing the implied fair value of each reporting unit with its carrying amount that includes goodwill. If the carrying amount of the reporting unit exceeds its implied fair value, Woodward compares the implied fair value of goodwill with the recorded carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value of goodwill, an impairment loss would be recognized to reduce the carrying amount to its implied fair value. Based on the results of Woodward’s annual goodwill impairment testing, no impairment charges were recorded in the year ended September 30, 2021 or since the goodwill was originally recorded due to the annual goodwill impairment test. Other intangibles: Other intangibles are recognized apart from goodwill whenever an acquired intangible asset arises from contractual or other legal rights, or whenever it is capable of being separated or divided from the acquired entity and sold, transferred, licensed, rented, or exchanged, either individually or in combination with a related contract, asset, or liability. Woodward amortizes the cost of other intangibles over their useful lives unless such lives are deemed indefinite. The cost of finite-lived other intangibles are amortized over their respective useful life using patterns that reflect the periods over which the economic benefits of the assets are expected to be realized. Amortization expense is allocated to cost of goods sold and selling, general, and administrative expenses based on the nature of the intangible asset. Finite-lived other intangible assets are reviewed for impairment whenever an event occurs or circumstances change indicating that the related carrying amount of the other intangible asset may not be recoverable. Impairment losses are recognized if the carrying amount of an intangible is both not recoverable and exceeds its fair value. Woodward has recorded no impairment charges related to its other intangibles as of September 30, 2021 or since the other intangibles were originally recorded due to the annual goodwill impairment test. Estimated lives over which intangible assets are amortized at September 30, 2021 were as follows: Customer relationships and contracts 15 – 30 years Intellectual property 15 – 17 years Process technology 10 – 30 years Woodward has one indefinitely lived intangible asset consisting of the Woodward L’Orange trade name. The Woodward L’Orange trade name intangible asset is tested for impairment on an annual basis and more often if an event occurs or circumstances change that indicate the fair value of the Woodward L’Orange intangible asset may be below its carrying amount. The impairment test consists of comparing the fair value of the Woodward L’Orange trade name intangible asset, determined using discounted cash flows, with its carrying amount. If the carrying amount of the Woodward L’Orange intangible asset exceeds its fair value, an impairment loss would be recognized to reduce the carrying amount to its fair value. Woodward has not recorded any impairment charges. Impairment of long-lived assets: Woodward reviews the carrying amount of its long-lived assets or asset groups to be used in operations whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset, or a significant decline in the observable market value of an asset, among others. If such facts indicate a potential impairment, the Company would assess the recoverability of an asset group by determining if the carrying amount of the asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life of the primary asset in the asset group. If the recoverability test indicates that the carrying amount of the asset group is not recoverable, the Company will estimate the fair value of the asset group using appropriate valuation methodologies, which would typically include an estimate of discounted cash flows. Any impairment would be measured as the difference between the asset group’s carrying amount and its estimated fair value. Investment in marketable equity securities: Woodward holds marketable equity securities related to its deferred compensation program. Based on Woodward’s intentions regarding these instruments, marketable equity securities are classified as trading securities. The trading securities are reported at fair value, with realized gains and losses recognized in “Other (income) expense, net.” The trading securities are included in “Other assets.” The associated obligation to provide benefits under the deferred compensation program is included in “Other liabilities.” Investments in unconsolidated subsidiaries: Investments in, and operating results of, entities in which Woodward does not have a controlling financial interest or the ability to exercise significant influence over the operations are included in the financial statements using the cost method of accounting. Investments and operating results of entities in which Woodward does not have a controlling interest but does have the ability to exercise significant influence over operations are included in the financial statements using the equity method of accounting. Deferred compensation: The Company maintains a deferred compensation plan, or “rabbi trust,” as part of its overall compensation package for certain employees. Deferred compensation obligations will be settled either by delivery of a fixed number of shares of Woodward’s common stock (in accordance with certain eligible members’ irrevocable elections) or in cash. Woodward has contributed shares of its common stock into a trust established for the future settlement of deferred compensation obligations that are payable in shares of Woodward’s common stock. Common stock held by the trust is reflected in the Consolidated Balance Sheets as “Treasury stock held for deferred compensation” and the related deferred compensation obligation is reflected as a separate component of equity in amounts equal to the fair value of the common stock at the dates of contribution. These accounts are not adjusted for subsequent changes in the fair value of the common stock. Deferred compensation obligations that will be settled in cash are accounted for on an accrual basis in accordance with the terms of the underlying contract and are reflected in the Consolidated Balance Sheet as “Other liabilities.” Financial instruments: The Company’s financial instruments include cash and cash equivalents, short-term investments, investments in the deferred compensation program, notes receivable from municipalities, investments in term deposits, cross-currency interest rate swaps and debt. Because of their short-term maturity, the carrying amount of cash and cash equivalents, and short-term debt approximate fair value. Financial assets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon a fair value hierarchy established by U.S. GAAP, which prioritizes the inputs used to measure fair value into the following levels: Level 1: Inputs based on quoted market prices in active markets for identical assets or liabilities at

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Standards	Note 2. New accounting standards From time to time, the Financial Accounting Standards Board (“FASB”) or other standards setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification (“ASC”) are communicated through issuance of an Accounting Standards Update (“ASU”). Recently adopted or anticipated impacts of significant future ASU’s are described below, as applicable. 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.” The purpose of ASU 2020-04 is to provide optional guidance for a limited time to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting. In response to concerns about structural risks of interbank offered rates, and, in particular, the risk of cessation of the London Interbank Offered Rate (LIBOR), reference rate reform refers to a global initiative to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. Once elected for a topic or an industry subtopic, the amendments in ASU 2020-04 must be applied prospectively for all eligible contract modifications for that topic or industry subtopic. Woodward has assessed the accounting and financial impact of ASU 2020-04, and concluded no financial assets or liabilities, including those involved in hedging relationships, will be materially impacted as a result of the cessation of LIBOR. Accordingly, Woodward will not elect to apply the amendments in ASU 2020-04 for contract modifications. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 amends ASC 740 to simplify the accounting for income taxes by removing certain exceptions for investments, intraperiod allocations and interim calculations, and adding guidance to reduce complexity in the accounting standard under the FASB’s simplification initiative. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020 (fiscal year 2022 for Woodward). Upon adoption, the amendments in ASU 2019-12 should be applied on a prospective basis to all periods presented. Woodward elected to early adopt the new guidance effective January 1, 2021, which did not have a material effect on the Consolidated Financial Statements. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 adds a current expected credit loss (“CECL”) impairment model to U.S. GAAP that is based on expected losses rather than incurred losses. Modified retrospective adoption is required with any cumulative-effect adjustment recorded to retained earnings as of the beginning of the period of adoption. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019 (fiscal year 2021 for Woodward), including interim periods within the year of adoption. Woodward adopted ASU 2016‐13, and all applicable amendments, on October 1, 2020 using the modified retrospective adoption method. Based on the nature of the Company’s financial instruments included within the scope of this standard, the adoption did not have a material effect on the Consolidated Financial Statements. See details of the Company’s allowance for uncollectible amounts and change in expected credit losses for billed receivables and unbilled receivables (contract assets) at Note 3, Revenue

Revenue From Contract With Customer [Abstract]
Revenue	Note 3. Revenue Sales of Products Woodward primarily generates revenue through the manufacture and sale of engineered aerospace and industrial products, including revenue derived from MRO performance obligations performed on products originally manufactured by Woodward and subsequently returned by OEM or other end-user customers. The majority of Woodward’s costs incurred to satisfy MRO performance obligations are related to replacing and/or refurbishing component parts of the returned products to restore the units back to a condition generally comparable to that of the unit upon its initial sale to an OEM customer. Therefore, Woodward considers almost all of its revenue to be derived from product sales, including those related to MRO. Year Ended September 30, 2021 2020 2019 Manufactured products 86 % 86 % 86 % MRO 13 % 12 % 12 % Services 1 % 2 % 2 % Point in time and over time revenue recognition The amount of revenue recognized as point in time or over time follows: For the Year Ended September 30, 2021 2020 2019 Aerospace Industrial Consolidated Aerospace Industrial Consolidated Aerospace Industrial Consolidated Point in time $ 481,422 $ 527,233 $ 1,008,655 $ 590,817 $ 592,157 $ 1,182,974 $ 762,042 $ 634,219 $ 1,396,261 Over time 922,695 314,482 1,237,177 1,000,146 312,545 1,312,691 1,118,478 385,458 1,503,936 Total net sales $ 1,404,117 $ 841,715 $ 2,245,832 $ 1,590,963 $ 904,702 $ 2,495,665 $ 1,880,520 $ 1,019,677 $ 2,900,197 Material Rights and Costs to Fulfill a Contract Amounts recognized related to changes in estimated total lifetime sales for material rights and costs to fulfill contracts with customers follows: For the Year Ended September 30, 2021 2020 2019 Revenue $ 2,671 $ 6,784 $ 6,017 Cost of goods sold 1,961 6,638 9,580 Amounts recognized related to amortization of costs to fulfill contracts and contract liabilities, which were not related to changes in estimate, follows: For the Year Ended September 30, 2021 2020 2019 Revenue $ 4,455 $ 1,664 $ 719 Cost of goods sold 3,466 1,241 376 As of September 30, 2021, “Other assets” on the Consolidated Balance Sheets included $152,885 of capitalized costs to fulfill contracts with customers, compared to $133,349 as of September 30, 2020. Accounts Receivable and Contract assets Customer receivables include amounts billed and currently due from customers as well as unbilled amounts (contract assets) and are included in “Accounts receivable” in Woodward’s Consolidated Balance Sheets. Amounts are billed in accordance with contractual terms, which are generally tied to shipment of the products to the customer, or as work progresses in accordance with contractual terms. Billed accounts receivable are typically due within 60 days. Woodward’s contracts with customers generally have no financing components. Accounts receivable consisted of the following: September 30, 2021 September 30, 2020 Billed receivables Trade accounts receivable $ 298,951 $ 307,914 Other (Chinese financial institutions) 23,168 56,640 Total billed receivables 322,119 364,554 Current unbilled receivables (contract assets) 204,596 181,792 Total accounts receivable 526,715 546,346 Less: Allowance for uncollectible amounts (3,664 ) (8,359 ) Total accounts receivable, net $ 523,051 $ 537,987 As of September 30, 2021, “Other assets” on the Consolidated Balance Sheets includes $9,424 of unbilled receivables not expected to be invoiced and collected within a period of twelve months, compared to $16,751 as of September 30, 2020. Unbilled receivables not expected to be invoiced and collected within a period of twelve months are primarily attributable to customer delays for deliveries on firm orders in the Aerospace segment due to the impacts of the COVID-19 pandemic. Billed and unbilled accounts receivable from the U.S. Government were less than 10% The allowance for uncollectible amounts and change in expected credit losses for trade accounts receivable and unbilled receivables (contract assets) consisted of the following: Year Ended September 30, 2021 2020 2019 Balance, beginning $ 8,359 $ 8,936 $ 3,938 Charged to costs and expenses, or sales allowance 2,382 4,735 5,927 Deductions (7,255 ) (5,342 ) (1,180 ) Other additions 1 178 30 251 Balance, ending $ 3,664 $ 8,359 $ 8,936 (1) Includes effects of foreign exchange rate changes during the period. Woodward adopted ASU 2016-13 on October 1, 2021. The change in the allowance for uncollectible amounts during the fiscal year ended September 30, 2020 and 2019 is based on incurred losses rather than expected credit losses per the CECL impairment model. Contract liabilities Contract liabilities consisted of the following: September 30, 2021 September 30, 2020 Current Noncurrent Current Noncurrent Deferred revenue from material rights from GE joint venture formation $ 4,771 $ 234,237 $ 4,066 $ 234,240 Deferred revenue from advanced invoicing and/or prepayments from customers 4,192 290 3,239 85 Liability related to customer supplied inventory 14,169 — 14,955 — Deferred revenue from material rights related to engineering and development funding 6,395 151,797 2,360 132,317 Net contract liabilities $ 29,527 $ 386,324 $ 24,620 $ 366,642 The current portion of contract liabilities is included in “Accrued liabilities” and the noncurrent portion is included in “Other liabilities” of Woodward’s Consolidated Balance Sheets. Woodward recognized revenue of $19,925 in the year ended September 30, 2021 from contract liabilities balances recorded as of September 30, 2020, compared to $29,579 in the year ended September 30, 2020 from contract liabilities balances recorded as of September 30, 2019. Woodward recognized revenue of $71,517 for the fiscal year 2021, compared to $79,569 for the fiscal year 2020 and $98,061 for fiscal year 2019, related to noncash consideration received from customers. The Aerospace segment recognized $69,195 for the fiscal year ended September 30, 2021, compared to $78,179 for the fiscal year ended September 30, 2020 and $96,762 for the fiscal year ended September 30, 2019, while the Industrial segment recognized $2,322 for the fiscal year ended September 30, 2021 compared to $1,390 for the fiscal year ended September 30, 2020 and $1,299 for the fiscal year ended September 30, 2019. Remaining performance obligations Remaining performance obligations related to the aggregate amount of the total contract transaction price of firm orders for which the performance obligation has not yet been recognized in revenue as of September 30, 2021 was $1,283,311, compared to $1,454,406 as of September 30, 2020, the majority of which in both periods relate to Woodward’s Aerospace segment. Woodward expects to recognize almost all of these remaining performance obligations within two years after September 30, 2021. Remaining performance obligations related to material rights that have not yet been recognized in revenue as of September 30, 2021 was $471,133, of which $11,265 is expected to be recognized in fiscal year 2022, and the balance is expected to be recognized thereafter. Woodward expects to recognize revenue from performance obligations related to material rights over the life of the underlying programs, which may be as long as forty years. Disaggregation of Revenue Woodward designs, produces and services reliable, efficient, low-emission, and high-performance energy control products for diverse applications in markets throughout the world. Woodward reports financial results for each of its Aerospace and Industrial reportable segments. Woodward further disaggregates its revenue from contracts with customers by primary market and by geographical area as Woodward believes this best depicts how the nature, amount, timing and uncertainty of its revenue and cash flows are affected by economic factors.

Earnings Per Share [Abstract]
Earnings Per Share	Note 4. Earnings per share Basic earnings per share is computed by dividing net earnings available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted earnings per share reflects the weighted-average number of shares outstanding after consideration of the dilutive effect of stock options and restricted stock. The following is a reconciliation of net earnings to basic earnings per share and diluted earnings per share: Year Ended September 30, 2021 2020 2019 Numerator: Net earnings $ 208,649 $ 240,395 $ 259,602 Denominator: Basic shares outstanding 63,287 62,267 61,950 Dilutive effect of stock options and restricted stock units 2,268 1,942 2,548 Diluted shares outstanding 65,555 64,209 64,498 Income per common share: Basic earnings per share $ 3.30 $ 3.86 $ 4.19 Diluted earnings per share $ 3.18 $ 3.74 $ 4.02 The following stock option grants were outstanding during the fiscal years ended September 30, 2021, 2020 and 2019, but were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive.

Leases [Abstract]
Leases	Note 5. Leases Woodward is primarily a lessee in lease arrangements but has some embedded lessor arrangements. Lessee arrangements Woodward has entered into operating leases for certain facilities and equipment with terms in excess of one year under agreements that expire at various dates. Some leases require the payment of property taxes, insurance, maintenance costs, or other similar costs in addition to rental payments. Woodward has also entered into finance leases for equipment with terms in excess of one year under agreements that expire at various dates. None of Woodward’s lease agreements contain significant residual value guarantees, restrictions, or covenants. As of September 30, 2021, Woodward has not entered into any lease arrangements that have not yet commenced but would create significant rights and obligations. Woodward does not have any lease transactions between related parties. Lease-related assets and liabilities follows: Classification on Consolidated Balance Sheets September 30, 2021 September 30, 2020 Assets: Operating lease assets Other assets $ 19,370 $ 18,918 Finance lease assets Property, plant and equipment, net 781 1,201 Total lease assets 20,151 20,119 Current liabilities: Operating lease liabilities Accrued liabilities 5,260 4,925 Finance lease liabilities Current portion of long-term debt 728 1,634 Noncurrent liabilities: Operating lease liabilities Other liabilities 14,770 14,569 Finance lease liabilities Long-term debt, less current portion 475 1,173 Total lease liabilities $ 21,233 $ 22,301 In the first quarter of fiscal year 2020, Woodward determined that the approved plan to divest of the renewable power systems business and other related businesses (as described more fully in Note 10, Sale of businesses Supplemental lease-related information follows: September 30, 2021 September 30, 2020 Weighted average remaining lease term Operating leases 4.3 years 5.5 years Finance leases 1.7 years 2.1 years Weighted average discount rate Operating leases 3.2 % 3.2 % Finance leases 2.8 % 3.0 % Lease-related expenses were as follows: Year Ended September 30, 2021 2020 Operating lease expense $ 6,559 $ 6,164 Amortization of financing lease assets 425 476 Interest on financing lease liabilities 58 87 Variable lease expense 1,495 1,101 Short-term lease expense 283 466 Sublease income 1 (680 ) (697 ) Total lease expense $ 8,140 $ 7,597 (1) Relates to two separate subleases Woodward has entered into for a leased manufacturing building in Niles, Illinois.

If, in the future, customers reduce purchases of related products from Woodward, the Company believes it will derive additional value from the underlying equipment by repurposing its use to support other customer arrangements. Woodward recognizes revenue from the embedded lessor arrangements based on the value of the underlying dedicated property, plant, and equipment. There are no fixed payments that the customers under the embedded lessor arrangements are obligated to pay. Therefore, all the customer payments under the embedded lessor arrangements are considered variable with the associated leasing revenue recognized when the revenue from underlying product sale related to variable lease payment is recognized .

Equity Method Investments And Joint Ventures [Abstract]
Joint Venture	Note 6. Joint venture In fiscal year 2016, Woodward and General Electric Company (“GE”), acting through its GE Aviation business unit, consummated the formation of a strategic joint venture between Woodward and GE (the “JV”) to develop, manufacture and support fuel systems for specified existing and all future GE commercial aircraft engines that produce thrust in excess of fifty thousand pounds. Unamortized deferred revenue from material rights in connection with the JV formation included: September 30, 2021 September 30, 2020 Accrued liabilities $ 4,771 $ 4,066 Other liabilities 234,237 234,240 Amortization of the deferred revenue (material right) recognized as an increase to sales was $4,191 for the fiscal year ended September 30, 2021, $5,493 for the fiscal year ended September 30, 2020, and $7,652 for the fiscal year ended September 30, 2019. Woodward and GE jointly manage the JV and any significant decisions and/or actions of the JV require the mutual consent of both parties. Neither Woodward nor GE has a controlling financial interest in the JV, but both Woodward and GE do have the ability to significantly influence the operating and financial decisions of the JV. Therefore, Woodward is accounting for its 50% ownership interest in the JV using the equity method of accounting. The JV is a related party to Woodward. In addition, GE will continue to pay contingent consideration to Woodward consisting of fifteen annual payments of $4,894 each, which began on January 4, 2017, subject to certain claw-back conditions. Woodward received its third and fourth annual payments of $4,894 during the three-months ended March 31, 2020 and March 31, 2021, respectively, which were recorded as deferred income and included in Net cash provided by operating activities on the Consolidated Statements of Cash Flows. Neither Woodward nor GE contributed any tangible assets to the JV. Other income related to Woodward’s equity interest in the earnings of the JV was as follows: For the Year Ended September 30, 2021 2020 2019 Other income $ 11,366 $ 15,580 $ 12,932 Cash distributions to Woodward from the JV, recognized in Net cash provided by operating activities on the Consolidated Statements of Cash Flows, from the JV include: For the Year Ended September 30, 2021 2020 2019 Cash distributions $ 13,500 $ 14,000 $ 15,000 Net sales to the JV were as follows: For the Year Ended September 30, 2021 2020 2019 Net sales 1 $ 35,957 $ 48,222 $ 60,955 (1) Net sales include a reduction of $21,101 for the fiscal year ended September 30, 2021, $23,904 for the fiscal year ended September 30, 2020, and $34,236 for the fiscal year ended September 30, 2019 related to royalties owed to the JV by Woodward on sales by Woodward directly to third party aftermarket customers The Consolidated Balance Sheets include “Accounts receivable” related to amounts the JV owed Woodward, “Accounts payable” related to amounts Woodward owed the JV, and “Other assets” related to Woodward’s net investment in the JV, as follows: September 30, 2021 September 30, 2020 Accounts receivable $ 3,639 $ 3,062 Accounts payable 2,823 1,502 Other assets 6,988 9,123 Woodward records in “Other liabilities” amounts invoiced to the JV for support of the JV’s engineering and development projects as an increase to contract liabilities, and records in “Other assets” related incurred expenditures as costs to fulfill a contract. Woodward’s contract liabilities classified as “Other liabilities” included amounts invoiced to the JV as of September 30, 2021 of $73,657 compared to $70,618 as of fiscal year ended September 30, 2020. Woodward’s costs to fulfill a contract included in “Other assets” related to JV activities were $73,657 as of September 30, 2021 and $70,618 as of fiscal year ended September 30, 2020. In the fiscal year ended September 30, 2021, Woodward recognized a $2,072 reduction in the contract liability in “Other liabilities” and a $2,072 reduction in costs to fulfill a contract in “Other assets” related to the recognition of revenue and cost of goods sold that was included in the contract liability and contract asset, respectively, at the beginning of the fiscal year. In the fiscal year ended September 30, 2020, Woodward recognized a $6,609 reduction in the contract liability in “Other liabilities” and a $6,261 reduction in costs to fulfill a contract in “Other assets” related to the termination of a JV engineering and development project previously recognized as a material right. No reductions in costs to fulfill a contract or contract liabilities were recorded during the fiscal year ended September 30, 2021 as a result of the termination of joint venture engineering and development projects.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	Note 7. Financial instruments and fair value measurements The table below presents information about Woodward’s financial assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation techniques Woodward utilized to determine such fair value. At September 30, 2021 At September 30, 2020 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Financial assets: Investments in term deposits with foreign banks $ 13,187 — — $ 13,187 $ 40,453 — — $ 40,453 Equity securities 29,714 — — 29,714 25,381 — — 25,381 Total financial assets $ 42,901 $ — $ — $ 42,901 $ 65,834 $ — $ — $ 65,834 Financial liabilities: Cross currency interest rate swaps $ — $ 50,185 $ — $ 50,185 $ — $ 51,387 $ — $ 51,387 Total financial liabilities $ — $ 50,185 $ — $ 50,185 $ — $ 51,387 $ — $ 51,387 Investments in term deposits with foreign banks: Woodward’s foreign subsidiaries sometimes invest excess cash in various highly liquid financial instruments that Woodward believes are with creditworthy financial institutions. Such investments are reported in “Cash and cash equivalents” at fair value, with realized gains from interest income recognized in earnings. The carrying value of Woodward’s investments in term deposits with foreign banks are considered equal to the fair value given the highly liquid nature of the investments. Equity securities: Woodward holds marketable equity securities, through investments in various mutual funds, related to its deferred compensation program. Based on Woodward’s intentions regarding these instruments, marketable equity securities are classified as trading securities. The trading securities are reported at fair value, with realized gains and losses recognized in “Other (income) expense, net” on the Consolidated Statements of Earnings. The trading securities are included in “Other assets” in the Consolidated Balance Sheets. The fair values of Woodward’s trading securities are based on the quoted market prices for the net asset value of the various mutual funds. Cross-currency interest rate swaps: Woodward holds cross currency interest rate swaps, which are accounted for at fair value. The swaps in an asset position are included in “Other assets,” and swaps in a liability position are included in “Other liabilities” in the Consolidated Balance Sheets. The fair values of Woodward’s cross currency interest rate swaps are determined using a market approach that is based on observable inputs other than quoted market prices, including contract terms, interest rates, currency rates, and other market factors. Cash, trade accounts receivable, accounts payable, and short-term borrowings are not remeasured to fair value, as the carrying cost of each approximates its respective fair value. The estimated fair values and carrying costs of other financial instruments that are not required to be remeasured at fair value in the Consolidated Balance Sheets were as follows : At September 30, 2021 At September 30, 2020 Fair Value Hierarchy Level Estimated Fair Value Carrying Cost Estimated Fair Value Carrying Cost Assets: Notes receivable from municipalities 2 $ 11,413 $ 10,193 $ 13,413 $ 11,846 Note receivable from sale of disposal group 2 6,288 6,061 6,341 6,061 Investments in short-term time deposits 2 11,587 11,580 13,678 13,671 Liabilities: Long-term debt 2 $ 812,866 $ 736,706 $ 935,610 $ 840,654 In connection with certain economic incentives related to Woodward’s development of a second campus in the greater-Rockford, Illinois area for its Aerospace segment and Woodward’s development of a new campus at its corporate headquarters in Fort Collins, Colorado, Woodward received long-term notes from municipalities within the states of Illinois and Colorado. The fair value of the long-term notes was estimated based on a model that discounted future principal and interest payments received at an interest rate available to the Company at the end of the period for similarly rated municipal notes of similar maturity, which is a level 2 input as defined by the U.S. GAAP fair value hierarchy. The interest rates used to estimate the fair value of the long-term notes were 1.3% at September 30, 2021 and 1.2% at September 30, 2020. In connection with the sale of the disposal group (See Note 10, Sale of businesses September 30, 2020 From time to time, certain of Woodward’s foreign subsidiaries will invest excess cash in short-term time deposits with a fixed maturity date of longer than three months but less than one year from the date of the deposit. Woodward believes that the investments are with creditworthy financial institutions. The fair value of the investments in short-term time deposits was estimated based on a model that discounted future principal and interest payments to be received at an interest rate available to the foreign subsidiary entering into the investment for similar short-term time deposits of similar maturity. This was determined to be a level 2 input as defined by the U.S. GAAP fair value hierarchy. The interest rates used to estimate the fair value of the short-term time deposits was 3.3% at September 30, 2021 and 4.4% at September 30, 2020. The fair value of long-term debt was estimated based on a model that discounted future principal and interest payments at interest rates available to the Company at the end of the period for similar debt of the same maturity, which is a level 2 input as defined by the U.S. GAAP fair value hierarchy. The weighted-average interest rates used to estimate the fair value of long-term debt were 1.6% at September 30, 2021 and 1.5% at September 30, 2020.

Derivative Instruments And Hedges [Abstract]
Derivative Instruments and Hedging Activities	Note 8. Derivative instruments and hedging activities Derivative instruments not designated or qualifying as hedging instruments In May 2018, Woodward entered into cross currency interest rate swap agreements that synthetically converted $167,420 of floating-rate debt under Woodward’s then existing revolving credit agreement to Euro denominated floating-rate debt in conjunction with the L’Orange acquisition (the “Floating-Rate Cross Currency Swap”). Also, in May 2018, Woodward entered into cross currency interest rate swap agreements that synthetically converted an aggregate principal amount of $400,000 of fixed-rate debt associated with the 2018 Note Purchase Agreement (as defined in Note 15, Credit facilities short-term borrowings and long-term debt Credit facilities short-term borrowings and long-term debt In May 2020, as a result of the COVID-19 pandemic and uncertainties in future cash flows, Woodward terminated the Floating-Rate Cross-Currency Swap and Fixed-Rate Cross-Currency Swaps . At the date of settlement, the total notional value of the Floating-Rate Cross-Currency Swap and Fixed-Rate Cross-Currency Swaps was $ 108,823 and $ 400,000 , respectively . Woodward received net cash proceeds of $ 59,571 , which includes $ 58,191 related to the fair value of the derivative assets and $ 4,380 of net accrued interest, less payment of $ 3,000 for fees to terminate the swap agreements . The proceeds received for the fair value of the instruments is recorded in “Other”, while net accrued interest is recorded in “Other” and “Accrued liabilities”, respectively, in cash flows provided by operating activities of Woodward’s Consolidated Statements of Cash Flows . The fees to terminate the swap agreements were expensed as incurred and presented in the line item “Selling, general and administrative” expenses in Woodward’s Consolidated Statements of Earnings. Upon termination and settlement of the instruments, Woodward entered into a new floating-rate cross-currency interest rate swap (the “2020 Floating-Rate Cross-Currency Swap”), with a notional value of $45,000, and five fixed-rate cross-currency interest rate swap agreements (the “2020 Fixed-Rate Cross-Currency Swaps”), with an aggregate notional value of $400,000, which effectively reduce the interest rates on the underlying fixed and floating-rate debt under the 2018 Notes and Woodward’s existing revolving credit agreement, respectively. The net interest income of the cross-currency interest rate swaps is recorded as a reduction to “Interest expense” in Woodward’s Consolidated Statements of Earnings. As of September 30, 2021, the total notional value of the 2020 Floating-Rate Cross-Currency Swap and 2020 Fixed-Rate Cross-Currency Swaps was $26,250 and $400,000, respectively. See Note 7, Financial Instruments and fair value measurements Derivatives instruments in fair value hedging relationships Concurrent with the entry into the Floating-Rate Cross Currency Swap in May 2018, a corresponding Euro denominated intercompany loan receivable with identical terms and notional amount as the underlying Euro denominated floating-rate debt, with a reciprocal cross currency interest rate swap, was entered into by Woodward Barbados Financing SRL (“Barbados”), a wholly owned subsidiary of Woodward, and is designated as a fair value hedge under the criteria prescribed in ASC Topic 815, Derivatives and Hedging In May 2020, Woodward settled the Euro denominated intercompany loan receivable with identical terms and notional value to the Floating-Rate Cross-Currency Swap and reciprocal intercompany cross-currency interest rate swap. The fair value hedge designated on these instruments was discontinued at the date of settlement and resulted in a reclassification of $1,719 of previously unrecognized losses from accumulated OCI into earnings. The loss on discontinuation of the fair value hedging relationship is recognized in “Gain on cross-currency interest rate swaps, net” in Woodward’s Consolidated Statements of Earnings. Concurrent with settlement of the Floating-Rate Cross-Currency Swap and discontinuation of the previous fair value hedging relationship, a US dollar denominated intercompany loan payable with identical terms and notional value as the 2020 Floating-Rate Cross-Currency Swap, together with a reciprocal intercompany floating-rate cross-currency interest rate swap, was entered into by Woodward Barbados Euro Financing SRL (“Euro Barbados”), a wholly owned subsidiary of Woodward. The US dollar denominated intercompany loan and reciprocal intercompany floating-rate cross-currency interest rate swap is designated as a fair value hedge under the criteria prescribed in ASC 815. The objective of the derivative instrument is to hedge against the foreign currency exchange risk attributable to the spot remeasurement of the US dollar denominated intercompany loan, as Euro Barbados maintains a Euro functional currency. For each floating-rate intercompany cross-currency interest rate swap, only the change in the fair value related to the cross-currency basis spread, or excluded component, of the derivative instrument is recognized in accumulated OCI. The remaining change in the fair value of the derivative instrument is recognized in foreign currency transaction gain or loss included in “Selling, general and administrative costs” in Woodward’s Consolidated Statements of Earnings. The change in the fair value of the derivative instrument in foreign currency transaction gain or loss offsets the change in the spot remeasurement of the intercompany Euro and US dollar denominated loans. Hedge effectiveness is assessed based on the fair value changes of the derivative instrument, after excluding any fair value changes related to the cross-currency basis spread. The initial cost of the cross-currency basis spread is recorded in earnings each period through the swap accrual process. There are no credit-risk-related contingent features associated with the intercompany floating-rate cross-currency interest rate swap. Derivative instruments in cash flow hedging relationships In conjunction with the entry into the Fixed-Rate Cross Currency Swaps in May 2018, five corresponding intercompany loans receivable, with identical terms and amounts of each tranche of the underlying aggregate principal amount of $400,000 of fixed-rate debt, and reciprocal cross currency interest rate swaps were entered into by Barbados, which are designated as cash flow hedges under the criteria prescribed in ASC 815. The objective of these derivative instruments is to hedge the risk of variability in cash flows attributable to the foreign currency exchange risk of cash flows for future principal and interest payments associated with the Euro denominated intercompany loans over a fifteen-year period. In May 2020, Woodward settled the Euro denominated intercompany loans receivable with identical terms and notional value to the Fixed-Rate Cross-Currency Swaps and reciprocal cross-currency interest rate swaps. The cash flow hedges designated on these instruments were discontinued at the date of settlement and resulted in a reclassification of $32,200 of previously unrecognized gains from accumulated OCI into earnings. The gain on discontinuation of the cash flow hedging relationships is recognized in “Gain on cross-currency interest rate swaps, net” in Woodward’s Consolidated Statements of Earnings. Concurrent with settlement of the Fixed-Rate Cross-Currency Swaps and the discontinuation of the previous cash flow hedging relationships, five corresponding US dollar intercompany loans payable, with identical terms and notional values of each tranche of the 2020 Fixed-Rate Cross-Currency Swaps, together with reciprocal fixed-rate intercompany cross-currency interest rate swaps were entered into by Euro Barbados, which are designated as cash flow hedges under the criteria prescribed in ASC 815. The objective of these derivative instruments is to hedge the risk of variability in cash flows attributable to the foreign currency exchange risk of cash flows for future principal and interest payments associated with the US dollar denominated intercompany loans over a thirteen-year period, as Euro Barbados maintains a Euro functional currency. For each of the fixed-rate intercompany cross-currency interest rate swaps, changes in the fair values of the derivative instruments are recognized in accumulated OCI and reclassified to foreign currency transaction gain or loss included in “Selling, general and administrative costs” in Woodward’s Consolidated Statements of Earnings. Reclassifications out of accumulated OCI of the change in fair value occur each reporting period based upon changes in the spot rate remeasurement of the Euro and US dollar denominated intercompany loans, including associated interest. Hedge effectiveness is assessed based on the fair value changes of the derivative instruments and such hedges are deemed to be highly effective in offsetting exposure to variability in foreign exchange rates. There are no credit-risk-related contingent features associated with these fixed-rate cross-currency interest rate swaps. Derivatives instruments in net investment hedging relationships On September 23, 2016, Woodward and Woodward International Holding B.V., a wholly owned subsidiary of Woodward organized under the laws of The Netherlands (the “BV Subsidiary”), each entered into a note purchase agreement (the “2016 Note Purchase Agreement”) relating to the sale by Woodward and the BV Subsidiary of an aggregate principal amount of €160,000 of senior unsecured notes in a series of private placement transactions.

Discontinued Operations And Disposal Groups [Abstract]
Sale of businesses	Note 10. Sale of businesses In the first quarter of fiscal year 2020, Woodward’s board of directors (“the Board”) approved a plan to divest Woodward’s renewable power systems business, protective relays business, and other businesses within the Company’s Industrial segment (collectively, the “disposal group”). Woodward determined that the approved plan to divest the disposal group represented a triggering event requiring (i) the net assets of the disposal group to be classified as held for sale and (ii) the long-lived assets attributable to the disposal group be assessed for impairment. Given the facts and circumstances at that time, Woodward determined that the value of the long-lived assets of the disposal group, including goodwill, intangible assets, ROU assets and property, plant, and equipment, were not recoverable and a $22,900 non-cash impairment charge was recorded during the fiscal year ended September 30, 2020. The non-cash impairment charge removed all the goodwill, intangible assets, ROU assets and property, plant, and equipment associated with the disposal group from the Consolidated Balance Sheets as of June 30, 2020. Further, on the approval of the divestiture plan and subsequent marketing of the disposal group, Woodward determined that based on the current market conditions, the carrying value of the disposal group’s remaining held for sale net assets exceeded the fair value. As a result, Woodward recorded a valuation allowance to reduce the carrying value of the net assets of the disposal group to their fair value . The non-cash impairment charge associated with the long-lived assets, and related valuation allowance for the other remaining net assets attributable to the disposal group, resulted in a total impairment charge of $ 37,902 . In determining the amount by which the carrying value of the disposal group’s remaining net assets exceeded their fair value, Woodward considered primarily the market value of the assets held for sale based on negotiations it had entered into with affiliates of the AURELIUS Group for the sale of the majority of the disposal group. On January 31, 2020, Woodward entered into a definitive agreement to sell the majority of the disposal group to affiliates of the AURELIUS Group for $23,400, subject to customary purchase price adjustments, consisting of cash and a $6,000 promissory note, which is due by April 30, 2022. The assets were primarily located in Germany, Poland and Bulgaria and accounted for approximately $88,000 of sales in fiscal year 2019. The valuation reserve recorded to reduce the carrying value of the net assets held for sale was based on the estimated selling price pursuant to the definitive agreement reduced by the estimated working capital adjustments, transaction costs, and anticipated losses on assets held for sale that were not included in the disposal group to be sold to the AURELIUS Group. The transactions consummating the sale of the disposal group were completed on April 30, 2020. The carrying value of the assets and liabilities sold were as follows: June 30, 2020 Assets: Accounts receivable $ 17,637 Inventories 441 Other current assets 796 Other assets 51 Total assets 18,925 Liabilities: Accounts payable 7,633 Accrued liabilities 2,998 Other liabilities 450 Total liabilities $ 11,081

On December 30, 2019, the Company closed on the sale of one of two parcels of real property at the Duarte facility and recorded a pre-tax gain on sale of assets of $13,522. On August 11, 2020, the Company closed on the sale of the final parcel of real property at the Duarte facility and recorded a pre-tax gain on sale of assets of $8,801. During the three-months ended December 31, 2019, Woodward determined that the approved plan to divest of the disposal group represented a triggering event requiring the long-lived assets attributable to the disposal group be assessed for impairment. Given the facts and circumstances at that time, Woodward determined that the remaining value of the plant, property and equipment of the disposal group was not recoverable, and a $13,421 non-cash impairment charge was recorded during fiscal year 2020. On September 25, 2020 the Company closed on the sale of its Loveland, Colorado campus with a concurrent purchase of a new property in Windsor, Colorado for future operations, resulting in recognition of a pre-tax gain on sale of assets of $2,330.

Given the facts and circumstances at the time, Woodward determined that the remaining value of the goodwill of the disposal group was not recoverable and an $8,640 non-cash impairment charge was recorded during the fiscal year ended September 30, 2020 Woodward tests goodwill for impairment at the reporting unit level on an annual basis or at any time there is an indication goodwill may be impaired, commonly referred to as triggering events. Woodward completed its annual goodwill impairment test as of July 31, 2021 during the quarter ended September 30, 2021 Forecasted cash flows used in the July 31, 2021 impairment test were discounted using weighted-average cost of capital assumptions ranging from 9.23% to 12.08%. The terminal values of the forecasted cash flows were calculated using the Gordon Growth Model and assumed an annual compound growth rate after five years of 3.37%. These inputs, which are unobservable in the market, represent management’s best estimate of what market participants would use in determining the present value of the Company’s forecasted cash flows. Changes in these estimates and assumptions can have a significant impact on the fair value of forecasted cash flows. Woodward evaluated the reasonableness of the reporting units’ resulting fair values utilizing a market multiple method. The results of Woodward’s goodwill impairment test performed as of July 31, 2021 did not indicate impairment of any of Woodward’s reporting units.

The impairment test consists of comparing the fair value of the Woodward L’Orange trade name intangible asset, determined using discounted cash flows based on the relief from royalty method under the income approach, with its carrying amount. If the carrying amount of the Woodward L’Orange trade name intangible asset exceeds its fair value, an impairment loss would be recognized to reduce the carrying amount to its fair value. Woodward has not recognized any impairment charges for this asset. During the fourth quarter, Woodward completed its annual impairment test of the Woodward L’Orange trade name intangible asset as of July 31, 2021 for the fiscal year ended September 30, 2021. The fair value of the Woodward L’Orange trade name intangible assets was determined using discounted cash flows based on the relief from royalty method under the income approach. This method represents a Level 3 input (based upon a fair value hierarchy established by U.S. GAAP) and incorporates various estimates and assumptions, the most significant being projected revenue growth rates, royalty rates, future tax rates and the present value, based on an estimated weighted-average cost of capital (or the discount rate) and terminal growth rate, of the forecasted cash flow. Management projects revenue growth rates and cash flows based on Woodward L’Orange’s current operational results, expected performance and operational strategies over a five year period. These projections are adjusted to reflect current economic conditions and demand for certain products, and require considerable management judgment. The forecasted cash flow used in the July 31, 2021 impairment test was discounted using weighted-average cost of capital assumption of 9.40%. The terminal value of the forecasted cash flow was calculated using the Gordon Growth Model and assumed an annual compound growth rate after five years of 3.37%. These inputs, which are unobservable in the market, represent management’s best estimate of what market participants would use in determining the present value of the Company’s forecasted cash flows. Changes in these estimates and assumptions can have a significant impact on the fair value of the forecasted cash flow. The results of impairment test performed as of July 31, 2021 indicated the estimated fair value of the Woodward L’Orange trade name intangible asset was in excess of its carrying value, and accordingly, no impairment existed. Finite-lived intangible assets During the three-months ended December 31, 2019, Woodward determined that the approved plan to divest of the disposal group represented a triggering event requiring the long-lived assets attributable to the disposal group be assessed for impairment. Given the facts and circumstances at that time, Woodward determined that the remaining value of the intangible assets of the disposal group was not recoverable and a $200 non-cash impairment charge was recorded for the fiscal year ended September 30, 2020.

The Revolving Credit Agreement provided for the option to increase available borrowings up to $1,500,000, subject to lenders’ participation. Borrowings under the Revolving Credit Agreement can be made by Woodward and certain of its foreign subsidiaries in U.S. dollars or in foreign currencies other than the U.S. dollar and generally bear interest at LIBOR plus 0.875% to 1.75%. The Revolving Credit Agreement matures on June 19, 2024. Under the Revolving Credit Agreement, there were no borrowings outstanding as of September 30, 2021 The Revolving Credit Agreement contains certain covenants customary with such agreements, which are generally consistent with the covenants applicable to Woodward’s long-term debt agreements, and contains customary events of default, including certain cross default provisions related to Woodward’s other outstanding debt arrangements in excess of $60,000, the occurrence of which would permit the lenders to accelerate the amounts due thereunder. In addition, the Revolving Credit Agreement includes the following financial covenants: (i) a maximum permitted leverage ratio of consolidated net debt to consolidated earnings before interest, taxes, depreciation, stock-based compensation, and amortization, plus any usual non-cash charges to the extent deducted in computing net income and transaction costs associated with permitted acquisitions (incurred within six-months of the permitted acquisition), minus any usual non-cash gains to the extent added in computing net income (“Leverage Ratio”) for Woodward and its consolidated subsidiaries of 3.5 to 1.0, which ratio, subject to certain restrictions, may increase to 4.0 to 1.0 for each period of four consecutive quarters during which a permitted acquisition occurs, and (ii) a minimum consolidated net worth of $1,156,000 plus (a) 50% of Woodward’s positive net income for the prior fiscal year and (b) 50% of Woodward’s net cash proceeds resulting from certain issuances of stock, subject to certain adjustments. Woodward’s obligations under the Revolving Credit Agreement are guaranteed by Woodward FST, Inc., Woodward MPC, Inc., and Woodward HRT, Inc., each of which is a wholly owned subsidiary of Woodward. Short-term borrowings Woodward has other foreign lines of credit and foreign overdraft facilities at various financial institutions, which are generally reviewed annually for renewal and are subject to the usual terms and conditions applied by the financial institutions.

Woodward issued the Series G, H and I Notes (the “First Closing Notes”) on October 1, 2013. Woodward issued the Series J, K and L Notes (the “Second Closing Notes” and with the First Closing Notes, collectively the “USD Notes”) on November 15, 2013. On November 15, 2020, Woodward paid the entire principal balance of $100,000 on the Series G and J Notes. On September 23, 2016, Woodward and the BV Subsidiary each entered into note purchase agreements (the “2016 Note Purchase Agreements”) relating to the sale by Woodward and the BV Subsidiary of an aggregate principal amount of €160,000 of senior unsecured notes in a series of private placement transactions. Woodward issued €40,000 Series M Notes. The BV Subsidiary issued (a) €77,000 aggregate principal amount of the BV Subsidiary’s Series N Senior Notes (the “Series N Notes”) and (b) €43,000 aggregate principal amount of the BV Subsidiary’s Series O Senior Notes (the “Series O Notes” and together with the Series M Notes and the Series N Notes, the “2016 Notes”). On May 31, 2018, Woodward entered into a note purchase agreement (the “2018 Note Purchase Agreement”) relating to the sale by Woodward of an aggregate principal amount of $400,000 of senior unsecured notes comprised of (a) $85,000 aggregate principal amount of its Series P Senior Notes (the “Series P Notes”), (b) $85,000 aggregate principal amount of its Series Q Senior Notes (the “Series Q Notes”), (c) $75,000 aggregate principal amount of its Series R Senior Notes (the “Series R Notes”), (d) $75,000 aggregate principal amount of its Series S Senior Notes (the “Series S Notes”), and (e) $80,000 aggregate principal amount of its Series T Senior Notes (the “Series T Notes”, and together with the Series P Notes, the Series Q Notes, the Series R Notes, and the Series S Notes, the “2018 Notes,” and, together with the USD Notes and 2016 Notes, the “Notes”), in a series of private placement transactions. In connection with the issuance of the 2018 Notes, the Company entered into cross currency swap transactions in respect of each tranche of the 2018 Notes, which effectively reduced the interest rates on the Series P Notes to 1.82% per annum, the Series Q Notes to 2.15% per annum, the Series R Notes to 2.42% per annum, the Series S Notes to 2.55% per annum and the Series T Notes to 2.90% per annum. Following the termination and settlement of the Floating-Rate Cross-Currency Swap and Fixed-Rate Cross-Currency Swaps entered into in 2018, the Company entered into the 2020 Floating-Rate Cross-Currency Swap and 2020 Fixed-Rate Cross-Currency Swaps, which effectively resulted in the interest rates on the Series P Notes being 3.44% per annum, the Series Q Notes to 3.44% per annum, the Series R Notes to 3.45% per annum, the Series S Notes to 3.50% per annum and the Series T Notes to 3.62% per annum (see Note 8, Derivative instruments and hedging activities). Interest on the remaining First Closing Notes, and the Series K and L Notes is payable semi-annually on April 1 and October 1 of each year until all principal is paid. Interest on the 2016 Notes is payable semi-annually on March 23 and September 23 of each year, until all principal is paid. None of the Notes were registered under the Securities Act of 1933 and they may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. Holders of the Notes do not have any registration rights. All of the issued Notes are held by multiple institutions. Woodward’s payment and performance obligations under the Notes, including without limitation the obligations for payment of all principal, interest and any applicable prepayment compensation amount, are guaranteed by (i) Woodward FST, Inc., Woodward MPC, Inc., and Woodward HRT, Inc., each of which is a wholly owned subsidiary of Woodward, and (ii) in the case of the BV Subsidiary’s Series N and O Notes, by Woodward. Woodward’s obligations under the Notes rank equal in right of payment with all of Woodward’s other unsecured unsubordinated debt, including its outstanding debt under its revolving credit facility. The Notes contain restrictive covenants customary for such financings, including, among other things, covenants that place limits on Woodward’s ability to incur liens on assets, incur additional debt (including a leverage or coverage-based maintenance test), transfer or sell Woodward’s assets, merge or consolidate with other persons and enter into material transactions with affiliates. Under the financial covenants contained in the note purchase agreement governing each series of the Notes, Woodward’s priority debt may not exceed, at any time, 25% of its consolidated net worth. Woodward’s Leverage Ratio cannot exceed 4.0 to 1.0 during any material acquisition period, or 3.5 to 1.0 at any other time on a rolling four quarter basis. In the event that Woodward’s Leverage Ratio exceeds 3.5 to 1.0 during any material acquisition period, the interest rate on each series of Notes will increase. The minimum consolidated net worth, prior year positive net income, and net cash proceeds resulting from certain issuances of stock for satisfaction of Woodward’s leverage ratio are consistent between the Notes and Revolving Credit Agreement.

Unamortized debt issuance costs associated with the Notes of $1,856 as of September 30, 2021 and $2,171 as of September 30, 2020 were recorded as a reduction in “Long-term debt, less current portion” in the Consolidated Balance Sheets. Unamortized debt issuance costs associated with Woodward’s Revolving Credit Agreements of $1,644 as of September 30, 2021 and $2,242 as of September 30, 2020 were recorded as “Other assets” in the Consolidated Balance Sheets. Amortization of debt issuance costs is included in operating activities in the Consolidated Statements of Cash Flows.

Restructuring charges of $5,008 were recorded during the fiscal year ended September 30, 2021 as nonsegment expenses, the majority of which are expected to be paid within twelve months. In fiscal year 2020, the Company committed to a plan of termination (the “Termination Plan”), as well as other cost savings actions, in response to the ongoing global economic challenges resulting from the COVID-19 pandemic and its impact on the Company’s business. The Termination Plan involved the termination and/or furlough of employees and contractors at certain of the Company’s operating facilities, primarily in the United States. As a result of the Termination Plan and other related actions, the Company incurred $23,673 of restructuring charges for employee severance and benefits costs as of September 30, 2020, with the majority of the cash expenditures being paid by September 30, 2020. All of the restructuring charges recorded during the fiscal year ended September 30, 2020 were recorded as nonsegment expenses and were paid as of September 30, 2021.

A portion of these NOL carryforwards were utilized in the current year. The majority of the NOL carryforwards as of September 30, 2021 expire at various times beginning in fiscal years 2023 through 2027, and Woodward has recognized valuation allowances against all NOL carryforwards that are less than 50 percent likely to be realized. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Both positive and negative evidence are considered in forming Woodward’s judgment as to whether a valuation allowance is appropriate, and more weight is given to evidence that can be objectively verified. Valuation allowances are reassessed whenever there are changes in circumstances that may cause a change in judgment. The change in the valuation allowance was primarily the result of recording a valuation allowance related to certain state tax credit carryforwards that we determined are not more likely than not realizable and the release of valuation of allowance at a wholly - owned subsidiary. At September 30, 2021, Woodward has not provided for taxes on undistributed foreign earnings of $302,000 that it considered indefinitely reinvested. These earnings could become subject to income taxes if they are remitted as dividends, are loaned to Woodward or any of Woodward’s subsidiaries located in the United States, or if Woodward sells its stock in the foreign subsidiaries. Any additional U.S. taxes could be offset, in part or in whole, by foreign tax credits. The amount of such taxes and application of tax credits would be dependent on the income tax laws and other circumstances at the time these amounts are repatriated. Based on these variables, it is impractical to determine the income tax liability that might be incurred if these funds were to be repatriated. The following is a reconciliation of the U.S. Federal statutory tax 21% in the fiscal years ended September 30, 2021, September 30, 2020 and September 30, 2019 to Woodward’s effective income tax rate: Year Ending September 30, 2021 2020 2019 Percent of pretax earnings Statutory tax rate 21.0 % 21.0 % 21.0 % State income taxes, net of federal tax benefit (0.5 ) 0.3 (0.1 ) Taxes on international activities (0.1 ) (2.1 ) 0.2 Research credit (3.1 ) (3.6 ) (3.3 ) Net excess income tax benefit from stock-based compensation (4.2 ) (2.8 ) (3.5 ) Adjustments of prior period tax items 0.4 1.0 0.9 Compensation and benefits 0.5 0.4 0.3 Transition Tax — — 3.3 Other items, net 1.1 0.5 0.2 Effective tax rate 15.1 % 14.7 % 19.0 % In determining the tax amounts in Woodward’s financial statements, estimates are sometimes used that are subsequently adjusted in the actual filing of tax returns or by updated calculations. In addition, Woodward occasionally has resolutions of tax items with tax authorities related to prior years due to the conclusion of audits and the lapse of applicable statutes of limitations. Such adjustments are included in the “Adjustments of prior period tax items” line in the above table. The increase in the effective tax rate for fiscal year 2021 compared to fiscal year 2020 is primarily attributable to (i) decreased current fiscal year foreign earnings in lower tax jurisdictions when compared to the prior fiscal year, and (ii) decreased Research and Development Credit in the current fiscal year when compared to the prior fiscal year. This increase is partially offset by (i) a larger favorable net excess income tax benefit from stock-based compensation, (ii) a favorable U.S. current fiscal year state tax provision when compared to the prior fiscal year, and (iii) a smaller detrimental adjustment to prior period tax items when compared to the prior fiscal year. A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits follows: Year Ending September 30, 2021 2020 2019 Beginning balance $ 9,851 $ 10,305 $ 8,364 Additions to current year tax positions 2,289 1,890 1,930 Reductions to prior year tax positions — (2,415 ) — Additions to prior year tax positions 3,166 71 11 Lapse of applicable statute of limitations (107 ) — — Ending balance $ 15,199 $ 9,851 $ 10,305 Included in the balance of unrecognized tax benefits were $8,724 as of September 30, 2021 and $4,730 as of September 30, 2020 of tax benefits that, if recognized, would affect the effective tax rate. At this time, Woodward estimates that it is reasonably possible that the liability for unrecognized tax benefits will decrease by as much as $5,385 in the next twelve months due to the completion of review by tax authorities, lapses of statutes, and the settlement of tax positions. Woodward accrues for potential interest and penalties related to unrecognized tax benefits and all other interest and penalties related to tax payments in tax expense. Woodward’s tax returns are subject to audits by U.S. federal, state, and foreign tax authorities, and these audits are at various stages of completion at any given time. Reviews of tax matters by authorities and lapses of the applicable statutes of limitation may result in changes to tax expense. Woodward’s fiscal years remaining open to examination for U.S. Federal income taxes include fiscal years 201 8 and thereafter. In fiscal year 2020, Woodward concluded its U.S. Federal income tax examination through fiscal year 201 7 , which included a foreign tax carryback to fiscal year 2016. Woodward’s fiscal years remaining open to examination for significant U.S. state income tax jurisdictions include fiscal years 201 7 and thereafter. Woodward closed various audits in foreign jurisdictions in the second and third quarters of fiscal year 20 20 . Consequently, fiscal years remaining open to examination in significant foreign jurisdictions include 201 6 and thereafter.

Compensation And Retirement Disclosure [Abstract]
Retirement benefits	Note 20. Retirement benefits Woodward provides various retirement benefits to eligible members of the Company, including contributions to various defined contribution plans, pension benefits associated with defined benefit plans, postretirement medical benefits and postretirement life insurance benefits. Eligibility requirements and benefit levels vary depending on employee location. Defined contribution plans Most of the Company’s U.S. employees are eligible to participate in the U.S. defined contribution plan. The U.S. defined contribution plan allows employees to defer part of their annual income for income tax purposes into their personal 401(k) accounts. The Company makes matching contributions to eligible employee accounts, which are also deferred for employee personal income tax purposes. Certain non-U.S. employees are also eligible to participate in similar non-U.S. plans. Prior to January 1, 2021 most of Woodward’s U.S. employees with at least two years of qualifying service (such two years of service, the “Initial Period of Service”) received an annual contribution of Woodward stock, generally equal to 5% of their eligible prior year wages, to their personal Woodward Retirement Savings Plan accounts (the “Stock Contribution”). In the second quarters of fiscal years 2021, 2020, and 2019, Woodward fulfilled its annual Woodward stock contribution obligation using shares held in treasury stock by issuing a total of 128 shares of common stock for a value of $14,900 in fiscal year 2021, 124 total shares of common stock for a value of $14,748 in fiscal year 2020, and 158 shares of common stock for a value of $14,846 in fiscal year 2019. The Woodward Retirement Savings Plan (the “WRS Plan”) held 2,760 shares of Woodward stock as of September 30, 2021 and 3,199 shares as of September 30, 2020. The shares held in the WRS Plan participate in dividends and are considered issued and outstanding for purposes of calculating basic and diluted earnings per share. Accrued liabilities included obligations to contribute shares of Woodward common stock to the WRS Plan of $11,588 as of September 30, 2021 and $11,230 as of September 30, 2020. Effective as of January 1, 2021, the Board amended the Woodward Retirement Savings Plan to eliminate the Initial Period Service for purposes of the Stock Contribution. Eligible U.S. employees are now generally eligible to receive the Stock Contribution if they are employed by the Company on the last day of the applicable calendar year without regard to service time. The first Company Stock Contribution under the amended contribution rules will be made during the second quarter of fiscal year 2022. The amount of expense associated with defined contribution plans was as follows: Year Ended September 30, 2021 2020 2019 Company costs $ 33,717 $ 33,769 $ 35,510 Defined benefit plans Woodward has defined benefit plans that provide pension benefits for certain retired employees in the United States, the United Kingdom, Japan, and Germany. Woodward also provides other postretirement benefits to its employees including postretirement medical benefits and life insurance benefits. Postretirement medical benefits are provided to certain current and retired employees and their covered dependents and beneficiaries in the United States and the United Kingdom. Life insurance benefits are provided to certain retirees in the United States under frozen plans, which are no longer available to current employees. A September 30 measurement date is utilized to value plan assets and obligations for all of Woodward’s defined benefit pension and other postretirement benefit plans. Excluding the Woodward HRT Plan, which is only partially frozen to salaried participants, the defined benefit plans in the United States were frozen in fiscal year 2007 and no additional employees may participate in the U.S. plans and no additional service costs will be incurred. Pension Plans The actuarial assumptions used in measuring the net periodic benefit cost and plan obligations of retirement pension benefits were as follows: At September 30, 2021 2020 2019 United States: Weighted-average assumptions to determine benefit obligation: Discount rate 3.05% 2.75% 3.25% Weighted-average assumptions to determine periodic benefit costs: Discount rate 2.75 3.25 4.35 Long-term rate of return on plan assets 7.15 7.39 7.39 The discount rate assumption is intended to reflect the rate at which the retirement benefits could be effectively settled based upon the assumed timing of the benefit payments. In the United States, Woodward uses a bond portfolio matching analysis based on recently traded, non-callable bonds rated AA or better that have at least $50 million outstanding to determine the benefit obligations at year end. At September 30, 2021 2020 2019 United Kingdom: Weighted-average assumptions to determine benefit obligation: Discount rate 2.05% 1.62% 1.74% Rate of compensation increase 3.80 3.30 3.50 Weighted-average assumptions to determine periodic benefit costs: Discount rate - service cost 1.71 1.79 2.70 Discount rate - interest cost 1.41 1.59 2.51 Rate of compensation increase 3.30 3.50 3.60 Long-term rate of return on plan assets 4.00 4.75 4.75 At September 30, 2021 2020 2019 Japan: Weighted-average assumptions to determine benefit obligation: Discount rate 0.92% 1.10 % 0.53 % Rate of compensation increase 2.00 2.00 2.00 Weighted-average assumptions to determine periodic benefit costs: Discount rate - service cost 1.33 0.72 0.80 Discount rate - interest cost 0.74 0.31 0.42 Rate of compensation increase 2.00 2.00 2.00 Long-term rate of return on plan assets 2.00 2.50 2.50 At September 30, 2021 2020 2019 Germany: Weighted-average assumptions to determine benefit obligation: Discount rate 1.36 % 0.97 % 0.81 % Rate of compensation increase 2.50 2.50 2.50 Weighted-average assumptions to determine periodic benefit costs: Discount rate - service cost 1.11 1.01 2.06 Discount rate - interest cost 0.76 0.56 1.53 Rate of compensation increase 2.50 2.50 2.50 In the United Kingdom, Germany and Japan, Woodward uses a high-quality corporate bond yield curve matched with separate cash flows to develop a single rate to determine the single rate equivalent to settle the entire benefit obligations in each jurisdiction. For the fiscal years ended September 30, 2021 and 2020, the discount rate used to determine periodic service cost and interest cost components of the overall benefit costs was based on spot rates derived from the same high-quality corporate bond yield curve used to determine the September 30, 2020 and 2019 benefit obligation, respectively, matched with separate cash flows for each future year. Compensation increase assumptions, where applicable, are based upon historical experience and anticipated future management actions. In determining the long-term rate of return on plan assets, Woodward assumes that the historical long-term compound growth rates of equity and fixed-income securities will predict the future returns of similar investments in the plan portfolio. Investment management and other fees paid out of the plan assets are factored into the determination of asset return assumptions. Mortality assumptions are based on published mortality studies developed primarily based on past experience of the broad population and modified for projected longevity trends. The projected benefit obligations in the United States as of September 30, 2021 and September 30, 2020 were based on the Society of Actuaries (“SOA”) Pri-2012 Mortality Tables Report using the SOA’s Mortality Improvement Scale MP-2019 (“MP-2019”) and projected forward using a custom projection scale based on MP-2019 with a 5-year convergence period and a long-term rate of 0.75%. As of September 30, 2021 and September 30, 2020, mortality assumptions in Japan were based on the Standard rates 2020 and mortality assumptions for the United Kingdom pension scheme were based on the Self-administered pension scheme (“SAPS”) S3 “all” tables with a projected 1.5% annual improvement rate. As of September 30, 2021, and September 30, 2020, mortality assumptions in Germany were based on the Heubeck 2018 G mortality tables. Net periodic benefit costs consist of the following components reflected as expense in Woodward’s Consolidated Statement of Earnings: Year Ended September 30, United States Other Countries Total 2021 2020 2019 2021 2020 2019 2021 2020 2019 Service cost $ 1,729 $ 1,659 $ 1,451 $ 2,922 $ 2,865 $ 2,036 $ 4,651 $ 4,524 $ 3,487 Interest cost 4,957 5,590 6,384 1,361 1,278 1,906 6,318 6,868 8,290 Expected return on plan assets (14,144 ) (12,346 ) (11,986 ) (2,482 ) (2,827 ) (2,638 ) (16,626 ) (15,173 ) (14,624 ) Amortization of: Net losses 541 1,430 617 931 1,046 283 1,472 2,476 900 Net prior service cost 969 936 709 25 23 — 994 959 709 Net periodic (benefit) cost $ (5,948 ) $ (2,731 ) $ (2,825 ) $ 2,757 $ 2,385 $ 1,587 $ (3,191 ) $ (346 ) $ (1,238 ) The following tables provide a reconciliation of the changes in the projected benefit obligation and fair value of assets for the defined benefit pension plans: At or for the Year Ended September 30, United States Other Countries Total 2021 2020 2021 2020 2021 2020 Changes in projected benefit obligation: Projected benefit obligation at beginning of year $ 184,077 $ 175,595 $ 123,546 $ 121,535 $ 307,623 $ 297,130 Plan amendment 611 — — — 611 — Service cost 1,729 1,659 2,922 2,865 4,651 4,524 Interest cost 4,957 5,590 1,361 1,278 6,318 6,868 Net actuarial losses (gains) (6,496 ) 7,811 (3,459 ) (4,841 ) (9,955 ) 2,970 Contribution by participants — 91 10 9 10 100 Benefits paid (7,532 ) (6,669 ) (3,782 ) (3,434 ) (11,314 ) (10,103 ) Settlements — — — (476 ) — (476 ) Foreign currency exchange rate changes — — 1,420 6,610 1,420 6,610 Projected benefit obligation at end of year $ 177,346 $ 184,077 $ 122,018 $ 123,546 $ 299,364 $ 307,623 Changes in fair value of plan assets: Fair value of plan assets at beginning of year $ 201,555 $ 170,556 $ 65,154 $ 63,577 $ 266,709 $ 234,133 Actual return on plan assets 27,240 37,577 4,675 576 31,915 38,153 Contributions by the Company — — 2,185 2,272 2,185 2,272 Contributions by plan participants — 91 10 9 10 100 Benefits paid (7,532 ) (6,669 ) (3,782 ) (3,434 ) (11,314 ) (10,103 ) Settlements — — — (476 ) — (476 ) Foreign currency exchange rate changes — — 1,602 2,630 1,602 2,630 Fair value of plan assets at end of year $ 221,263 $ 201,555 $ 69,844 $ 65,154 $ 291,107 $ 266,709 Net over/(under) funded status at end of year $ 43,917 $ 17,478 $ (52,174 ) $ (58,392 ) $ (8,257 ) $ (40,914 ) At September 30, 2021, the Company’s defined benefit pension plans in the United Kingdom, Japan and Germany represented $61,819, $9,786 and $50,413 of the total projected benefit obligation, respectively. At September 30, 2021, the United Kingdom and Japan pension plan assets represented $57,945 and $11,899 of the total fair value of all plan assets, respectively. The German pension plans are unfunded and have no plan assets. The largest contributor to the net actuarial gains affecting the funded status for the defined benefit pension plans in the United States is due to an increase in the discount rate. The largest contributor to the net actuarial gains affecting the benefit obligation for the defined benefit pension plans in the United Kingdom, Japan, and Germany is due to an increase in the discount rate. The accumulated benefit obligations of the Company’s defined benefit pension plans at September 30, 2021 was $177,346 in the United States, $60,690 in the United Kingdom, $8,958 in Japan, and $50,402 in Germany, and at September 30, 2020 was $184,077 in the United States, $58,198 in the United Kingdom, $9,266 in Japan and $54,403 in Germany.

The German pension plans are unfunded; therefore, benefit payments are made from Company contributions into these plans as required to meet the payment obligations. Using foreign exchange rates as of September 30, 2021 and expected future service assumptions, it is anticipated that the future benefit payments will be as follows: Year Ending September 30, United States Other Countries Total 2022 $ 8,393 $ 3,350 $ 11,743 2023 8,922 3,907 12,829 2024 9,349 3,810 13,159 2025 9,700 3,777 13,477 2026 9,988 3,759 13,747 2027 – 2031 52,659 22,325 74,984 Woodward expects its pension plan contributions in fiscal year 2022 will be $1,259 in the United Kingdom, $198 in Japan and $1,014 in Germany. Woodward expects to have no pension plan contributions in fiscal year 2022 in the United States. Pension plan assets The overall investment objective of the pension plan assets is to earn a rate of return over time which, when combined with Company contributions, satisfies the benefit obligations of the pension plans and maintains sufficient liquidity to pay benefits. As the timing and nature of the plan obligations varies for each Company sponsored pension plan, investment strategies have been individually designed for each pension plan with a common focus on maintaining diversified investment portfolios that provide for long-term growth while minimizing the risk to principal associated with short-term market behavior. The strategy for each of the plans balances the requirements to generate returns, using investments expected to produce higher returns, such as equity securities, with the need to control risk within the pension plans using less volatile investment assets, such as debt securities. A strategy of more equity-oriented allocation is adopted for those plans which have a longer-term investment plan based on the timing of the associated benefit obligations. Risks associated with the plan assets include interest rate fluctuation risk, market fluctuation risk, risk of default by debt issuers and liquidity risk. To manage these risks, the assets are managed by established, professional investment firms and performance is evaluated regularly by the Company’s pension oversight committee against specific benchmarks and each plan’s investment objectives. Liability management and asset class diversification are central to the Company’s risk management approach and overall investment strategy. The assets of the U.S. plans are invested in actively managed mutual funds. The assets of the plans in the United Kingdom and Japan are invested in actively managed pooled investment funds. Each individual mutual fund or pooled investment fund has been selected based on the investment strategy of the related plan, which mirrors a specific asset class within the associated target allocation. The plans in Germany are unfunded and have no plan assets. Pension plan assets at September 30, 2021 and 2020 do not include any direct investment in Woodward’s common stock. The asset allocations are monitored and rebalanced regularly by investment managers assigned to the individual pension plans. The actual allocations of pension plan assets and target allocation ranges by asset class, are as follows: At September 30, 2021 2020 Percentage of Plan Assets Target Allocation Ranges Percentage of Plan Assets Target Allocation Ranges United States: Asset Class Equity Securities 30.7 % 2.5% — 51.2% 64.4 % 41.7 % — 81.7 % Debt Securities 67.7 % 58.8% — 87.5% 35.0 % 28.3 % — 48.3 % Other 1.6 % 0.0% 0.6 % 0.0% 100.0 % 100.0 % United Kingdom: Asset Class Equity Securities 42.3 % 50.0 % — 90.0 % 39.6 % 50.0 % — 90.0 % Debt Securities 57.3 % 45.0 % — 70.0 % 60.1 % 45.0 % — 70.0 % Other 0.4 % 0.0% 0.3 % 0.0% 100.0 % 100.0 % Japan: Asset Class Equity Securities 40.3 % 36.0 % — 44.0 % 39.7 % 36.0 % — 44.0 % Debt Securities 58.8 % 55.0 % — 63.0 % 59.4 % 55.0 % — 63.0 % Other 0.9 % 0.0 % — 2.0 % 0.9 % 0.0 % — 2.0 % 100.0 % 100.0 % Actual allocations to each asset class can vary from target allocations due to periodic market value fluctuations, investment strategy changes, and the timing of benefit payments and contributions.

The fair value of the cash and cash equivalents are based on the quoted market price of the respective currency in which the cash is maintained. Pension assets invested in mutual funds : The assets of the Company’s U.S. pension plans are invested in various mutual funds which invest in both equity and debt securities. The fair value of the mutual funds is determined based on the quoted market price of each fund. Pension assets invested in pooled funds : The assets of the Company’s Japan and United Kingdom pension plans are invested in pooled investment funds, which include both equity and debt securities. The assets of the United Kingdom pension plan are invested in index-linked pooled funds which aim to replicate the movements of an underlying market index to which the fund is linked. Fair value of the pooled funds is based on the net asset value of shares held by the plan as reported by the fund sponsors. All pooled funds held by plans outside of the United States are considered to be invested in international equity and debt securities. Although the underlying securities may be largely domestic to the plan holding the investment assets, the underlying assets are considered international from the perspective of the Company. There were no transfers into or out of Level 3 assets in fiscal years 2021 or 2020. Other postretirement benefit plans Woodward provides other postretirement benefits to its employees including postretirement medical benefits and life insurance benefits. Postretirement medical benefits are provided to certain current and retired employees and their covered dependents and beneficiaries in the United States. Benefits include the option to elect company provided medical insurance coverage to age 65 and a Medicare supplemental plan after age 65. Life insurance benefits are also provided to certain retirees in the United States under frozen plans which are no longer available to current employees. A September 30 measurement date is utilized to value plan assets and obligations for Woodward’s other postretirement benefit plans. The postretirement medical benefit plans, other than the plan assumed in an acquisition in fiscal year 2009, were frozen in fiscal year 2006 and no additional employees may participate in the plans. Generally, employees who had attained age 55 and had rendered 10 or more years of service before the plans were frozen were eligible for these postretirement medical benefits. Certain participating retirees are required to contribute to the plans in order to maintain coverage. The plans provide postretirement medical benefits for approximately 7 retired employees and their covered dependents and beneficiaries and may provide future benefits to 425 active employees and their covered dependents and beneficiaries, upon retirement, if the employees elect to participate. All the postretirement medical plans are fully insured for retirees who have attained age 65. The actuarial assumptions used in measuring the net periodic benefit cost and plan obligations of postretirement benefits were as follows: At September 30, 2021 2020 2019 Weighted-average discount rate used to determine benefit obligation 2.80 % 2.45 % 3.05 % Weighted-average discount rate used to determine net periodic benefit cost 2.45 3.05 4.30 The discount rate assumption is intended to reflect the rate at which the postretirement benefits could be effectively settled based upon the assumed timing of the benefit payments. Woodward used a bond portfolio matching analysis based on recently traded, non-callable bonds rated AA or better that have at least $50 million outstanding to determine the benefit obligations at year end. Mortality assumptions are based on published mortality studies developed primarily based on past experience of the broad population and modified for projected longevity trends. The projected benefit obligations in the United States as of September 30, 2021 and September 30, 2020 were based on the SOA Pri-2012 Mortality Tables Report using the SOA’s MP-2019 and projected forward using a custom projection scale based on MP-2019 with a 5-year convergence period and a long-term rate of 0.75%. Assumed healthcare cost trend rates at September 30, were as follows: 2021 2020 Health care cost trend rate assumed for next year 6.00 % 6.00 % Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) 5.00 % 5.00 % Year that the rate reaches the ultimate trend rate 2027 2025 Net periodic benefit costs consist of the following components reflected as expense in Woodward’s Consolidated Statements of Earnings: Year Ended September 30, 2021 2020 2019 Service cost $ 1 $ 2 $ 5 Interest cost 599 782 1,154 Amortization of: Net losses 30 47 55 Net prior service cost (benefit) 1 3 (5 ) Net periodic cost $ 631 $ 834 $ 1,209 The following table provides a reconciliation of the changes in the accumulated postretirement benefit obligation and fair value of assets for the postretirement benefits: Year Ended September 30, 2021 2020 Changes in accumulated postretirement benefit obligation: Accumulated postretirement benefit obligation at beginning of year $ 25,445 $ 26,671 Service cost 1 2 Interest cost 599 782 Premiums paid by plan participants 993 1,088 Net actuarial gains (2,422 ) (313 ) Benefits paid (3,072 ) (2,785 ) Accumulated postretirement benefit obligation at end of year $ 21,544 $ 25,445 Changes in fair value of plan assets: Fair value of plan assets at beginning of year $ — $ — Contributions by the company 2,079 1,697 Premiums paid by plan participants 993 1,088 Benefits paid (3,072 ) (2,785 ) Fair value of plan assets at end of year $ — $ — Funded status at end of year $ (21,544 ) $ (25,445 ) The following tables provide the amounts recognized in the statement of financial position and accumulated other comprehensive losses for the postretirement plans: Year Ended September 30, 2021 2020 Amounts recognized in statement of financial position consist of: Accrued liabilities $ (1,808 ) $ (1,992 ) Other non-current liabilities (19,736 ) (23,453 ) Funded status at end of year $ (21,544 ) $ (25,445 ) Amounts recognized in accumulated other comprehensive income consist of: Unrecognized net prior service cost (benefit) $ - $ 1 Unrecognized net gains (2,815 ) (363 ) Total amounts recognized (2,815 ) (362 ) Deferred taxes 289 (324 ) Amounts recognized in accumulated other comprehensive income $ (2,526 ) $ (686 ) Woodward pays plan benefits from its general funds; therefore, there are no segregated plan assets as of September 30, 2021 or September 30, 2020. The accumulated benefit obligations of the Company’s postretirement plans were $21,544 at September 30, 2021 and $25,445 at September 30, 2020. The largest contributor to the actuarial gains affecting the Company’s postretirement plans accumulated benefit obligations were the claims experience being lower than expected and increase in discount rate. The following table reconciles the changes in accumulated other comprehensive losses for the other postretirement benefit plans: Year Ended September 30, 2021 2020 Accumulated other comprehensive losses at beginning of year $ (362 ) $ 1 Net gain (2,422 ) (313 ) Amortization of: Net losses (30 ) (47 ) Prior service (cost) benefit (1 ) (3 ) Accumulated other comprehensive losses at end of year $ (2,815 ) $ (362 ) Using expected future service, it is anticipated that the future Company contributions to pay benefits for other postretirement benefit plans, excluding participate contributions, will be as follows: Year Ending September 30, 2022 $ 2,799 2023 2,754 2024 2,699 2025 2,634 2026 2,554 2027 – 2031 11,089

Equity [Abstract]
Stockholders' Equity	Note 21. Stockholders’ equity Common Stock Holders of Woodward’s common stock are entitled to receive dividends when and as declared by the Board and have the right to one vote per share on all matters requiring stockholder approval. Dividends declared and paid were as follows: Year Ended September 30, 2021 2020 2019 Dividends declared and paid $ 36,041 $ 37,664 $ 39,066 Dividend per share amount 0.5688 0.6050 0.6300 Stock repurchase program In November 2019, the Board approved a program for the repurchase of up to $500,000 of Woodward’s outstanding shares of common stock on the open market or in privately negotiated transactions over a three year period that will end in 2022 (the “2019 Authorization”). In fiscal year 2021 Stock-based compensation Non-qualified stock option awards and restricted stock awards are granted to key management members and directors of the Company. The grant date for these awards is used for the measurement date. Vesting would be accelerated in the event of retirement, disability, or death of a participant, or change in control of the Company, as defined in the individual stock option agreements. These awards are valued as of the measurement date and are amortized on a straight-line basis over the requisite vesting period for all awards, including awards with graded vesting. Stock for exercised stock options and for restricted stock awards is issued from treasury stock shares. Provisions governing outstanding stock option awards are included in the 2017 Omnibus Incentive Plan, as amended from time to time (the “2017 Plan”) and the 2006 Omnibus Incentive Plan (the “2006 Plan”), as applicable. The 2017 Plan was approved by Woodward’s stockholders in January 2017 and is a successor plan to the 2006 Plan. As of September 14, 2016, the effective date of the 2017 Plan, the Board delegated authority to administer the 2017 Plan to the compensation committee of the board of directors (the “Committee”), including, but not limited to, the power to determine the recipients of awards and the terms of those awards. On January 29 , 20 20 , Woodward’s stockholders approved an additional shares of Woodward’s common stock to be made available for future grants. Under the 2017 Plan, there were approximately 2,714 shares of Woodward’s common stock available for future grants as of September 30, 2021 . Stock options Woodward believes that stock options align the interests of its employees and directors with the interests of its stockholders. Stock option awards are granted with an exercise price equal to the market price of Woodward’s stock at the date the grants are awarded, a ten-year The fair value of options granted is estimated as of the grant date using the Black-Scholes-Merton option-valuation model using the assumptions in the following table. Woodward calculates the expected term, which represents the average period of time that stock options granted are expected to be outstanding, based upon historical experience of plan participants. Expected volatility is based on historical volatility using daily stock price observations. The estimated dividend yield is based upon Woodward’s historical dividend practice and the market value of its common stock. The risk-free rate is based on the U.S. treasury yield curve, for periods within the contractual life of the stock option, at the time of grant. Year Ended September 30, 2021 2020 2019 Weighted-average exercise price per share $ 82.46 $ 90.52 $ 79.84 Expected term (years) 6.5 - 8.7 6.4 - 8.7 6.5 - 8.7 Estimated volatility 33.3 % - 36.2 % 25.7 % - 35.1 % 25.7 % - 31.0 % Estimated dividend yield 0.3 % - 0.6 % 0.4 % - 0.9 % 0.6 % - 0.8 % Risk-free interest rate 0.4 % - 1.0 % 0.4 % - 1.7 % 1.5 % - 3.1 % The weighted average grant date fair value of options granted follows: Year Ended September 30, 2021 2020 2019 Weighted-average grant date fair value of options $ 28.22 $ 25.41 $ 24.12 The following is a summary of the activity for stock option awards during the fiscal year ended September 30, 2021: Number Weighted- Average Exercise Price Per Share Balance at September 30, 2020 5,443 $ 62.00 Options granted 773 82.46 Options exercised (850 ) 41.01 Options forfeited (25 ) 81.75 Options expired (2 ) 46.55 Balance at September 30, 2021 5,339 68.21 Exercise prices of stock options outstanding as of September 30, 2021 range from $33.64 to $127.84.

Pursuant to the form stock option agreements used by the Company, with terms approved by the administrator of the applicable plan, the requisite service period can be less than the four-year vesting period based on grantee’s retirement eligibility. As such, the recognition of stock-based compensation expense associated with some stock option grants can be accelerated to a period of less than four years, including immediate recognition of stock-based compensation expense on the date of grant. Stock-based compensation expense recognized was as follows: Year Ended September 30, 2021 2020 2019 Employee stock-based compensation expense $ 21,475 $ 22,903 $ 18,146 At September 30, 2021

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 22. Commitments and contingencies Woodward enters into unconditional purchase obligation arrangements (i.e., issuance of purchase orders, obligations to transfer funds in the future for fixed or minimum quantities of goods or services at fixed or minimum prices, such as "take-or-pay" contracts) in the normal course of business to ensure that adequate levels of sourced product are available to Woodward. Future minimum unconditional purchase obligations are as follows: Year Ending September 30, 2022 $ 404,051 2023 36,292 2024 7,048 2025 1,333 2026 2,173 Thereafter 899 Total $ 451,796 The U.S. Government, and other governments, may terminate any of Woodward’s government contracts (and, in general, subcontracts) at their convenience, as well as for default based on specified performance measurements. If any of Woodward’s government contracts were to be terminated for convenience, the Company generally would be entitled to receive payment for work completed and allowable termination or cancellation costs. If any of Woodward’s government contracts were to be terminated for Woodward’s default, the U.S. Government generally would pay only for the work accepted, and could require Woodward to pay the difference between the original contract price and the cost to re-procure the contract items, net of the work accepted from the original contract. The U.S. Government could also hold Woodward liable for damages resulting from the default. Woodward is currently involved in claims, pending or threatened litigation or other legal proceedings, investigations and/or regulatory proceedings arising in the normal course of business, including, among others, those relating to product liability claims, employment matters, worker’s compensation claims, contractual disputes, product warranty claims and alleged violations of various laws and regulations. Woodward accrues for known individual matters using estimates of the most likely amount of loss where it believes that it is probable the matter will result in a loss when ultimately resolved and such loss is reasonably estimable. Legal costs are expensed as incurred and are classified in “Selling, general and administrative expenses” on the Consolidated Statements of Earnings. Woodward is partially self-insured in the United States for healthcare and worker’s compensation up to predetermined amounts, above which third party insurance applies. Management regularly reviews the probable outcome of related claims and proceedings, the expenses expected to be incurred, the availability and limits of the insurance coverage, and the established accruals for liabilities. While the outcome of pending claims, legal and regulatory proceedings, and investigations cannot be predicted with certainty, management believes that any liabilities that may result from these claims, proceedings and investigations will not have a material effect on Woodward’s liquidity, financial condition, or results of operations. In the event of a change in control of Woodward, as defined in change-in-control agreements with its current corporate officers, Woodward may be required to pay termination benefits to any such officer if such officer’s employment is terminated within two years following the change of control.

Segment Reporting [Abstract]
Segment Information	Note 23. Segment information Woodward serves the aerospace and industrial markets through its two reportable segments - Aerospace and Industrial. When appropriate, Woodward’s reportable segments are aggregations of Woodward’s operating segments. Woodward uses operating segment information internally to manage its business, including the assessment of operating segment performance and decisions for the allocation of resources between operating segments. The accounting policies of the reportable segments are the same as those of the Company. Woodward evaluates segment profit or loss based on internal performance measures for each segment in a given period. In connection with that assessment, Woodward generally excludes matters such as certain charges for restructuring, interest income and expense, certain gains and losses from asset dispositions, or other non-recurring and/or non-operationally related expenses. A summary of consolidated net sales and earnings by segment follows: Year Ended September 30, 2021 2020 2019 Segment external net sales: Aerospace $ 1,404,117 $ 1,590,963 $ 1,880,520 Industrial 841,715 904,702 1,019,677 Total consolidated net sales $ 2,245,832 $ 2,495,665 $ 2,900,197 Segment earnings: Aerospace $ 234,356 $ 310,137 $ 389,126 Industrial 108,672 100,321 93,521 Nonsegment expenses (64,442 ) (94,530 ) (119,447 ) Interest Expense, net (32,787 ) (34,047 ) (42,588 ) Consolidated earnings before income taxes $ 245,799 $ 281,881 $ 320,612 Segment assets consist of accounts receivable, inventories, property, plant, and equipment, net, goodwill, and other intangibles, net.

Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2021
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Woodward, Inc. and its subsidiaries (collectively “Woodward” or “the Company”). Dollar amounts contained in these Consolidated Financial Statements are in thousands, except per share amounts.
Nature of operations	Nature of operations Woodward is an independent designer, manufacturer, and service provider of energy control and optimization solutions. Woodward designs, produces and services reliable, efficient, low-emission, and high-performance energy control products for diverse applications in challenging environments. Woodward has significant production and assembly facilities primarily in the United States, Europe and Asia, and promotes its products and services through its worldwide locations. Woodward’s strategic focus is providing energy control and optimization solutions for the aerospace and industrial markets. The precise and efficient control of energy, including motion, fluid, combustion and electrical energy, is a growing requirement in the markets Woodward serves. Woodward’s customers look to it to optimize the efficiency, emissions and operation of power equipment in both commercial and defense operations. Woodward’s core technologies leverage well across its markets and customer applications, enabling it to develop and integrate cost-effective and state-of-the-art fuel, combustion, fluid, actuation and electronic systems. Woodward focuses its solutions and services primarily on serving original equipment manufacturers (“OEMs”) and equipment packagers, partnering with them to bring superior component and system solutions to their demanding applications. Woodward also provides aftermarket repair, maintenance, replacement and other service support for its installed products. Woodward’s components and integrated systems optimize performance of commercial aircraft, defense aircraft, military ground vehicles and other equipment, gas and steam turbines, industrial diesel, gas, biodiesel and dual-fuel reciprocating engines, and electrical power systems. Woodward’s innovative motion, fluid, combustion and electrical energy control systems help its customers offer more cost-effective, cleaner, and more reliable equipment. COVID-19 Pandemic When combined with the various measures enacted by governments and private organizations to contain COVID-19 or slow its spread, the pandemic has adversely impacted global activity and contributed to volatility in financial markets; and the Company has likewise been significantly impacted by the global COVID-19 pandemic. The COVID-19 pandemic could continue to have a material adverse impact on economic and market conditions and presents uncertainty and risk with respect to the Company and its performance and financial results, including estimates and assumptions used by management for the reported amount of assets and liabilities.
Principles of consolidation	Principles of consolidation: These Consolidated Financial Statements are prepared in accordance with U.S. GAAP and include the accounts of Woodward and its wholly and majority-owned subsidiaries. Transactions within and between these companies are eliminated.
Use of estimates	Use of estimates: The preparation of the Consolidated Financial Statements requires management to make use of estimates and assumptions that affect the reported amount of assets and liabilities, at the date of the financial statements and the reported revenues and expenses recognized during the reporting period, and certain financial statement disclosures. Significant estimates include allowances for uncollectible amounts, net realizable value of inventories, customer rebates earned, useful lives of property and identifiable intangible assets, the evaluation of impairments of property, identifiable intangible assets and goodwill, the provision for income tax and related valuation reserves, the valuation of assets and liabilities acquired in business combinations, assumptions used in the determination of the funded status and annual expense of pension and postretirement employee benefit plans, the valuation of stock compensation instruments granted to employees, and contingencies. Actual results could differ from those estimates.
Foreign currency exchange rates	Foreign currency exchange rates: The assets and liabilities of substantially all subsidiaries outside the United States are translated at fiscal year-end rates of exchange, and earnings and cash flow statements are translated at weighted-average rates of exchange. The exchange rate in effect at the time of the cash flow is used for significant or infrequent cash flows, such as payments for a business acquisition, for which the use of weighted-average rates of exchange would result in a substantially different cash flow. Translation adjustments are accumulated with other comprehensive (losses) earnings as a separate component of stockholders’ equity and are presented net of tax effects in the Consolidated Statements of Stockholders’ Equity. The effects of changes in foreign currency exchange rates on loans between consolidated subsidiaries that are considered permanent in nature are also accumulated with other comprehensive earnings, net of tax. The Company is exposed to market risks related to fluctuations in foreign currency exchange rates because some sales transactions, and certain assets and liabilities of its domestic and foreign subsidiaries, are denominated in foreign currencies. Selling, general, and administrative expenses include a net foreign currency loss of $1,986 in fiscal year 2021, a net foreign currency gain of $194 in fiscal year 2020, and a net foreign currency loss of $1,018 in fiscal year 2019.
Revenue recognition	Revenue recognition: Revenue is recognized on contracts with customers for arrangements in which quantities and pricing are fixed and/or determinable and are generally based on customer purchase orders, often within the framework of a long-term supply arrangement with the customer. Woodward has determined that it is the principal in its sales transactions, as Woodward is primarily responsible for fulfilling the promised performance obligations, has discretion to establish the selling price, and generally assumes the inventory risk. Woodward recognizes revenue for performance obligations within a customer contract when control of the associated product or service is transferred to the customer. Some of Woodward’s contracts with customers contain a single performance obligation, while other contracts contain multiple performance obligations. Each product within a contract generally represents a separate performance obligation as Woodward does not provide significant installation and integration services, the products do not customize each other, and the products can function independently of each other. A contract's transaction price is allocated to each performance obligation and recognized as revenue when, or as, the customer obtains control of the associated product or service. When there are multiple performance obligations within a contract, Woodward generally uses the observable standalone sales price for each distinct product or service within the contract to allocate the transaction price to the distinct products or services. In instances when a standalone sales price for each product or service is not observable within the contract, Woodward allocates the transaction price to each performance obligation using an estimate of the standalone selling price for each product or service, which is generally based on incurred costs plus a reasonable margin, for each distinct product or service in the contract. When determining the transaction price of each contract, Woodward considers contractual consideration payable by the customer and variable consideration that may affect the total transaction price. Variable consideration, consisting of early payment discounts, rebates and other sources of price variability, are included in the estimated transaction price based on both customer-specific information as well as historical experience.
Point in time and over time revenue recognition	Point in time and over time revenue recognition: Control of the products generally transfers to the customer at a point in time, as the customer does not control the products as they are produced. Performance obligations are satisfied and revenue is recognized over time if: (i) the customer receives the benefits as Woodward performs work, if the customer controls the asset as it is being enhanced, or if the product being produced for the customer has no alternative use to Woodward; and (ii) Woodward has an enforceable right to payment with a profit. For products being produced for the customer that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and where the products are substantially the same and have the same pattern of transfer to the customer, revenue is recognized as a series of distinct products. As Woodward satisfies manufacturing, repair and overhaul (“MRO”) performance obligations, revenue is recognized over time, as the customer, rather than Woodward, controls the asset being enhanced. When services are provided, revenue from those services is recognized over time because control is transferred continuously to customers as Woodward performs the work. For services that are not short-term in nature, MRO, and sales of products that have no alternative use to Woodward and an enforceable right to payment with a profit, Woodward uses an actual cost input measure to determine the extent of progress towards completion of the performance obligation. For these revenue streams, revenue is recognized over time as work is performed based on the relationship between actual costs incurred to-date for each contract and the total estimated costs for such contract at completion of the performance obligation (the cost-to-cost method). Woodward has concluded that this measure of progress best depicts the transfer of assets to the customer, because incurred costs are integral to Woodward’s completion of the performance obligation under the specific customer contract and correlate directly to the transfer of control to the customer. Contract costs include labor, material and overhead. Contract cost estimates are based on various assumptions to project the outcome of future events. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the performance of subcontractors; and the availability and timing of funding from the customer. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, Woodward recognizes provisions for estimated losses on uncompleted contracts in the period in which such losses are determined. In situations where the creditworthiness of a customer becomes in doubt, Woodward ceases to recognize the over-time revenue on the associated customer contract. Occasionally, Woodward sells maintenance or service arrangements, extended warranties, or other stand ready services. Woodward recognizes revenue from such arrangements as a series of performance obligations over the time period in which the services are available to the customer.
Material Rights and Costs to Fulfill a Contract	Material Rights and Costs to Fulfill a Contract : Customers sometimes pay consideration to Woodward for product engineering and development activities that do not result in the immediate transfer of distinct products or services to the customer. There is an implicit assumption that without the customer making such advance payments to Woodward, Woodward’s future sales of products or services to the customer would be at a higher selling price; therefore, such payments create a “material right” to the customer that effectively gives the customer an option to acquire future products or services, at a discount, that are dependent upon the product engineering and development. Material rights are recorded as contract liabilities and will be recognized when control of the related products or services are transferred to the customer. Woodward capitalizes costs of product engineering and development identified as material rights up to the amount of customer funding as costs to fulfill a contract because the costs incurred up to the amount of the customer funding commitment are recoverable. Due to the uncertainty of the product success and/or demand, fulfillment costs in excess of the customer funding are expensed as incurred. Woodward recognizes the deferred material rights as revenue based on a percentage of actual sales to total estimated lifetime sales of the related developed products as the customers exercise their option to acquire additional products or services at a discount. Woodward amortizes the capitalized costs to fulfill a contract as cost of goods sold proportionally to the recognition of the associated deferred material rights. Estimated total lifetime sales are reviewed at least annually and more frequently when circumstances warrant a modification to the previous estimate. Woodward does not capitalize incremental costs of obtaining a contract, as Woodward does not pay sales commissions or incur other incremental costs related to contracts with Woodward’s customers for arrangements in which quantities and pricing are fixed and/or determinable.
Contract Liabilities	Contract liabilities: Advance payments and billings in excess of revenue recognized represent contract liabilities and are recorded as deferred revenues when customers remit contractual cash payments in advance of Woodward satisfying performance obligations under contractual arrangements, including those with performance obligations satisfied over time. Woodward generally receives advance payments from customers related to maintenance or service arrangements, extended warranties, or other stand ready services, which it recognizes over the performance period. Contract liabilities are satisfied when revenue is recognized and the performance obligation is satisfied. Advance payments and billings in excess of revenue recognized are included in deferred revenue, which is classified as current or noncurrent based on the timing of when Woodward expects to recognize revenue.
Customer Payments	Customer payments : Woodward occasionally agrees to make payments to certain customers in order to participate in anticipated sales activity. Payments made to customers are accounted for as a reduction of revenue unless they are made in exchange for identifiable goods or services with fair values that can be reasonably estimated. Reductions in revenue associated with these customer payments are recognized immediately to the extent that the payments cannot be attributed to anticipated future sales, and are recognized in future periods to the extent that the payments relate to anticipated future sales. Such determinations are based on the facts and circumstances underlying each payment.
Stock-based compensation	Stock-based compensation: Compensation cost relating to stock-based payment awards made to employees and directors is recognized in the financial statements using a fair value method. Non-qualified stock option awards and restricted stock awards are issued under Woodward’s stock-based compensation plans. The cost of such awards, measured at the grant date, is based on the estimated fair value of the award. Forfeitures are estimated at the time of each grant in order to estimate the portion of the award that will ultimately vest. The estimate is based on Woodward’s historical rates of forfeitures and is updated periodically. The portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods, which is generally the vesting period of the awards.
Research and development costs	Research and development costs: Company funded expenditures related to new product development, and significant product enhancement and/or upgrade activities are expensed as incurred and are separately reported in the Consolidated Statements of Earnings
Income taxes	Income taxes: Deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of Woodward’s assets, liabilities, and certain unrecognized gains and losses recorded in accumulated other comprehensive (losses) earnings. Woodward provides for taxes that may be payable if undistributed earnings of overseas subsidiaries were to be remitted to the United States, except for those earnings that it considers to be indefinitely invested
Cash equivalents	Cash equivalents: Highly liquid investments purchased with an original maturity of three months or less are considered to be cash equivalents.
Accounts receivable	Accounts receivable: Almost all of Woodward’s sales are made on credit and result in accounts receivable, which are recorded at the amount invoiced and are generally not collateralized. In the normal course of business, not all accounts receivable are collected and, therefore, an allowance for uncollectible amounts is provided equal to the amount that Woodward believes ultimately will not be collected, either from credit risk or other adjustments to the original selling price or anticipated cash discounts. In establishing the amount of the allowance related to the credit risk of accounts receivable, customer-specific information is considered related to delinquent accounts, past loss experience, bankruptcy filings, deterioration in the customer’s operating results or financial position, current and forecasted economic conditions, and other relevant factors. Bad debt losses are deducted from the allowance, and the related accounts receivable balances are written off when the receivables are deemed uncollectible. Recoveries of accounts receivable previously written off are recognized when received. The allowance associated with anticipated other adjustments to the selling price or cash discounts is also established and is included in the allowance for uncollectible amounts. In establishing this amount, both customer-specific information as well as historical experience is considered. In coordination with its customers and when terms are considered favorable to Woodward, Woodward from time-to-time transfers ownership to collect amounts due to Woodward for outstanding accounts receivable to third parties in exchange for cash. When the transfer of accounts receivable meets the criteria of Financial Accounting Standards Board (“FASB”) ASC Topic 860-10, “Transfers and Servicing,” and are without recourse, it is recognized as a sale and the accounts receivable is derecognized. Unbilled receivables (contract assets) arise when the timing of billing differs from the timing of revenue recognized, such as when contract provisions require revenue to be recognized over time rather than at a point in time. Unbilled receivables primarily relate to performance obligations satisfied over time when the cost-to-cost method is utilized and the revenue recognized exceeds the amount billed to the customer as there is not yet a right to payment in accordance with contractual terms. Unbilled receivables are recorded as a contract asset when the revenue associated with the contract is recognized prior to billing and derecognized when billed in accordance with the terms of the contract. Consistent with common business practice in China, Woodward’s Chinese subsidiaries accept bankers’ acceptance notes from Chinese customers in settlement of certain customer billed accounts receivable. Bankers’ acceptance notes are financial instruments issued by Chinese financial institutions as part of financing arrangements between the financial institution and a customer of the financial institution. Bankers’ acceptance notes represent a commitment by the issuing financial institution to pay a certain amount of money at a specified future maturity date to the legal owner of the bankers’ acceptance note as of the maturity date. The maturity date of bankers’ acceptance notes varies, but it is Woodward’s policy to only accept bankers’ acceptance notes with maturity dates no more than 180 days from the date of Woodward’s receipt of such draft. Woodward has elected to adopt the practical expedient to not adjust the promised amounts of consideration for the effects of a significant financing component at contract inception as the financing component associated with accepting bankers’ acceptance notes has a duration of less than one year. Woodward’s contracts with customers generally have no other financing components. For composition of accounts receivable, see Note 3, Revenue.
Inventories	Inventories: Inventories are valued at the lower of cost or net realizable value, with cost being determined using methods that approximate a first-in, first-out basis.
Short-term investments	Short-term investments: From time to time, certain of Woodward’s foreign subsidiaries will invest excess cash in short-term time deposits with a fixed maturity date of longer than three months but less than one year from the date of the deposit. Woodward believes that the investments are with creditworthy financial institutions. Amounts with maturities of less than 365 days are classified as “Other current assets.”
Property, plant and equipment	Property, plant, and equipment: Property, plant, and equipment are recorded at cost and are depreciated over the estimated useful lives of the assets. Assets are generally depreciated using the straight-line method. Assets are tested for recoverability whenever events or circumstances indicate the carrying value may not be recoverable. Estimated lives over which fixed assets are generally depreciated at September 30, 2021 were as follows: Land improvements 3 – 20 years Buildings and improvements 3 – 40 years Leasehold improvements 1 – 10 years Machinery and production equipment 3 – 20 years Computer equipment and software 1 – 10 years Office furniture and equipment 3 – 10 years Other 3 – 10 years Included in computer equipment and software are Woodward’s enterprise resource planning (“ERP”) systems, which have an estimated useful life of 10 years. All other computer equipment and software is generally depreciated over three years to five years.
Leases	Leases: Right-of-use (“ROU”) assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the remaining fixed lease payments over the lease term. In determining the estimated present value of lease payments, Woodward discounts the fixed lease payments using the rate implicit in the agreement or, if the implicit rate is not known, using the incremental borrowing rate. Woodward’s incremental borrowing rate is based on the information available at the lease commencement date, with consideration given to Woodward’s recent debt issuances as well as publicly available data for instruments with similar characteristics. For operating leases, lease expense is recognized over the expected lease term and classified as a cost of goods sold or selling, general and administrative expense based on the nature of the underlying leased asset. For finance leases, the ROU asset is recognized over the shorter of the useful life of the asset, consistent with Woodward’s normal depreciation policy, or the lease term, and is classified as a cost of goods sold, selling, general and administrative expense, or research and development expense, based on the nature and use of the underlying leased asset. Certain of Woodward’s operating lease agreements include variable payments that are passed through by the landlord, such as insurance, taxes, and common area maintenance, payments based on the usage of the asset, and rental payments adjusted periodically for inflation. Pass-through charges, payments due to changes in usage of the asset, and payments due to changes in indexation are included within variable rent expense and are recognized in the period in which the variable obligation for the payments was incurred. Woodward is primarily a lessee in lease arrangements but has some embedded lessor arrangements.
Goodwill	Goodwill: Woodward tests goodwill for impairment at the reporting unit level on an annual basis and more often if an event occurs or circumstances change that indicates the fair value of a reporting unit may be below its carrying amount. Based on the relevant U.S. GAAP authoritative guidance, Woodward aggregates components of a single operating segment into a reporting unit, if appropriate. The impairment test consists of comparing the implied fair value of each reporting unit with its carrying amount that includes goodwill. If the carrying amount of the reporting unit exceeds its implied fair value, Woodward compares the implied fair value of goodwill with the recorded carrying amount of goodwill. If the carrying
Other intangibles	Other intangibles: Other intangibles are recognized apart from goodwill whenever an acquired intangible asset arises from contractual or other legal rights, or whenever it is capable of being separated or divided from the acquired entity and sold, transferred, licensed, rented, or exchanged, either individually or in combination with a related contract, asset, or liability. Woodward amortizes the cost of other intangibles over their useful lives unless such lives are deemed indefinite. The cost of finite-lived other intangibles are amortized over their respective useful life using patterns that reflect the periods over which the economic benefits of the assets are expected to be realized. Amortization expense is allocated to cost of goods sold and selling, general, and administrative expenses based on the nature of the intangible asset. Finite-lived other intangible assets are reviewed for impairment whenever an event occurs or circumstances change indicating that the related carrying amount of the other intangible asset may not be recoverable. Impairment losses are recognized if the carrying amount of an intangible is both not recoverable and exceeds its fair value. Woodward has recorded no impairment charges related to its other intangibles as of September 30, 2021 or since the other intangibles were originally recorded due to the annual goodwill impairment test. Estimated lives over which intangible assets are amortized at September 30, 2021 were as follows: Customer relationships and contracts 15 – 30 years Intellectual property 15 – 17 years Process technology 10 – 30 years Woodward has one indefinitely lived intangible asset consisting of the Woodward L’Orange trade name. The Woodward L’Orange trade name intangible asset is tested for impairment on an annual basis and more often if an event occurs or circumstances change that indicate the fair value of the Woodward L’Orange intangible asset may be below its carrying amount. The impairment test consists of comparing the fair value of the Woodward L’Orange trade name intangible asset, determined using discounted cash flows, with its carrying amount. If the carrying amount of the Woodward L’Orange intangible asset exceeds its fair value, an impairment loss would be recognized to reduce the carrying amount to its fair value. Woodward has not recorded any impairment charges.
Impairment of long-lived assets	Impairment of long-lived assets: Woodward reviews the carrying amount of its long-lived assets or asset groups to be used in operations whenever events or changes in circumstances indicate that the carrying amount of the assets might not be recoverable. Factors that would necessitate an impairment assessment include a significant adverse change in the extent or manner in which an asset is used, a significant adverse change in legal factors or the business climate that could affect the value of the asset, or a significant decline in the observable market value of an asset, among others. If such facts indicate a potential impairment, the Company would assess the recoverability of an asset group by determining if the carrying amount of the asset group exceeds the sum of the projected undiscounted cash flows expected to result from the use and eventual disposition of the assets over the remaining economic life of the primary asset in the asset group. If the recoverability test indicates that the carrying amount of the asset group is not recoverable, the Company will estimate the fair value of the asset group using appropriate valuation methodologies, which would typically include an estimate of discounted cash flows. Any impairment would be measured as the difference between the asset group’s carrying amount and its estimated fair value.
Investments in marketable equity securities	Investment in marketable equity securities: Woodward holds marketable equity securities related to its deferred compensation program. Based on Woodward’s intentions regarding these instruments, marketable equity securities are classified as trading securities. The trading securities are reported at fair value, with realized gains and losses recognized in “Other (income) expense, net.” The trading securities are included in “Other assets.” The associated obligation to provide benefits under the deferred compensation program is included in “Other liabilities.”
Investments in unconsolidated subsidiaries	Investments in unconsolidated subsidiaries: Investments in, and operating results of, entities in which Woodward does not have a controlling financial interest or the ability to exercise significant influence over the operations are included in the financial statements using the cost method of accounting. Investments and operating results of entities in which Woodward does not have a controlling interest but does have the ability to exercise significant influence over operations are included in the financial statements using the equity method of accounting.
Deferred compensation	Deferred compensation: The Company maintains a deferred compensation plan, or “rabbi trust,” as part of its overall compensation package for certain employees. Deferred compensation obligations will be settled either by delivery of a fixed number of shares of Woodward’s common stock (in accordance with certain eligible members’ irrevocable elections) or in cash. Woodward has contributed shares of its common stock into a trust established for the future settlement of deferred compensation obligations that are payable in shares of Woodward’s common stock. Common stock held by the trust is reflected in the Consolidated Balance Sheets as “Treasury stock held for deferred compensation” and the related deferred compensation obligation is reflected as a separate component of equity in amounts equal to the fair value of the common stock at the dates of contribution. These accounts are not adjusted for subsequent changes in the fair value of the common stock. Deferred compensation obligations that will be settled in cash are accounted for on an accrual basis in accordance with the terms of the underlying contract and are reflected in the Consolidated Balance Sheet as “Other liabilities.”
Financial instruments	Financial instruments: The Company’s financial instruments include cash and cash equivalents, short-term investments, investments in the deferred compensation program, notes receivable from municipalities, investments in term deposits, cross-currency interest rate swaps and debt. Because of their short-term maturity, the carrying amount of cash and cash equivalents, and short-term debt approximate fair value. Financial assets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon a fair value hierarchy established by U.S. GAAP, which prioritizes the inputs used to measure fair value into the following levels: Level 1: Inputs based on quoted market prices in active markets for identical assets or liabilities at the measurement date. Level 2: Quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable and can be corroborated by observable market data. Level 3: Inputs reflect management’s best estimates and assumptions of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation of the instruments. Further information on the fair value of financial instruments can be found at Note 7, Financial instruments and fair value measurements
Derivatives	Derivatives: The Company is exposed to various global market risks, including the effect of changes in interest rates, foreign currency exchange rates, changes in certain commodity prices and fluctuations in various producer indices. From time to time, Woodward enters into derivative instruments for risk management purposes only, including derivatives designated as accounting hedges and/or those utilized as economic hedges. Woodward uses interest rate related derivative instruments to manage its exposure to fluctuations of interest rates. Woodward does not enter into or issue derivatives for trading or speculative purposes. By using derivative and/or hedging instruments to manage its risk exposure, Woodward is subject, from time to time, to credit risk and market risk on those derivative instruments. Credit risk arises from the potential failure of the counterparty to perform under the terms of the derivative and/or hedging instrument. When the fair value of a derivative contract is positive, the counterparty owes Woodward, which creates credit risk for Woodward. Woodward mitigates this credit risk by entering into transactions only with counterparties that are believed to be creditworthy. Market risk arises from the potential adverse effects on the value of derivative and/or hedging instruments that result from a change in interest rates, commodity prices, or foreign currency exchange rates. Woodward minimizes this market risk by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. From time to time, in order to hedge against foreign currency exposure, Woodward designates certain non-derivative financial instrument loans as net investment hedges. Foreign exchange gains or losses on these loans are recognized in foreign currency translation adjustments within total comprehensive (losses) earnings. Also, to hedge against the foreign currency exposure attributable to non-functional currency denominated intercompany loans, Woodward has entered into derivative instruments in fair value hedging relationships and cash flow hedging relationships. Further information on net investment hedges and derivative instruments in fair value and cash flow hedging relationships, including the Company’s policy in accounting for these derivatives, can be found at Note 8 , Derivative instruments and hedging activities .
Postretirement benefits	Postretirement benefits: The Company provides various benefits to certain current and former employees through defined benefit pension and postretirement plans. For financial reporting purposes, net periodic benefits expense and related obligations are calculated using a number of significant actuarial assumptions. Changes in net periodic expense and funding status may occur in the future due to changes in these assumptions. The funded status of defined pension and postretirement plans recognized in the statement of financial position is measured as the difference between the fair market value of the plan assets and the benefit obligation. For a defined benefit pension plan, the benefit obligation is the projected benefit obligation; for any other defined benefit postretirement plan, such as a retiree health care plan, the benefit obligation is the accumulated benefit obligation. Any over-funded status is recognized as an asset and any underfunded status is recognized as a liability. Projected benefit obligation is the actuarial present value as of the measurement date of all benefits attributed by the plan benefit formula to employee service rendered before the measurement date using assumptions as to future compensation levels if the plan benefit formula is based on those future compensation levels. The accumulated benefit obligation is the actuarial present value of benefits (whether vested or unvested) attributed by the plan benefit formula to employee service rendered before the measurement date and based on employee service and compensation, if applicable, prior to that date. The accumulated benefit obligation differs from the projected benefit obligation in that it includes no assumption about future compensation levels.

Debt Instrument [Line Items]
Debt Instrument, Covenant Description		The Notes contain restrictive covenants customary for such financings, including, among other things, covenants that place limits on Woodward’s ability to incur liens on assets, incur additional debt (including a leverage or coverage-based maintenance test), transfer or sell Woodward’s assets, merge or consolidate with other persons and enter into material transactions with affiliates. Under the financial covenants contained in the note purchase agreement governing each series of the Notes, Woodward’s priority debt may not exceed, at any time, 25% of its consolidated net worth.  Woodward’s Leverage Ratio cannot exceed 4.0 to 1.0 during any material acquisition period, or 3.5 to 1.0 at any other time on a rolling four quarter basis.  In the event that Woodward’s Leverage Ratio exceeds 3.5 to 1.0 during any material acquisition period, the interest rate on each series of Notes will increase.  The minimum consolidated net worth, prior year positive net income, and net cash proceeds resulting from certain issuances of stock for satisfaction of Woodward’s leverage ratio are consistent between the Notes and Revolving Credit Agreement.

Debt Instrument, Covenant Description		The Revolving Credit Agreement contains certain covenants customary with such agreements, which are generally consistent with the covenants applicable to Woodward’s long-term debt agreements, and contains customary events of default, including certain cross default provisions related to Woodward’s other outstanding debt arrangements in excess of $60,000, the occurrence of which would permit the lenders to accelerate the amounts due thereunder.  In addition, the Revolving Credit Agreement includes the following financial covenants: (i) a maximum permitted leverage ratio of consolidated net debt to consolidated earnings before interest, taxes, depreciation, stock-based compensation, and amortization, plus any usual non-cash charges to the extent deducted in computing net income and transaction costs associated with permitted acquisitions (incurred within six-months of the permitted acquisition), minus any usual non-cash gains to the extent added in computing net income (“Leverage Ratio”) for Woodward and its consolidated subsidiaries of 3.5 to 1.0, which ratio, subject to certain restrictions, may increase to 4.0 to 1.0 for each period of four consecutive quarters during which a permitted acquisition occurs, and (ii) a minimum consolidated net worth of $1,156,000 plus (a) 50% of Woodward’s positive net income for the prior fiscal year and (b) 50% of Woodward’s net cash proceeds resulting from certain issuances of stock, subject to certain adjustments.
