[1]	On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[2]	Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[3]	Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.
[4]	Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[5]	Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.
[6]	Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .
[7]	The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.
[8]	In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation.

[1]	The adoption of ASC 606 changed the revenue recognition practices for a number of revenue generating activities across Woodward’s businesses, although the most significant impacts are concentrated in product being produced for customers that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and MRO. The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory.
[2]	The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.”
[3]	The value of tax assets and tax liabilities was impacted by the change in timing of the recognition of assets and liabilities within tax jurisdictions. T
[4]	The net book value of the backlog and customer relationships and contracts intangible assets was adjusted concurrent with the change in the timing of the associated revenue, resulting in a reduction in the net book value of these assets as of the date of adoption.
[5]	Woodward recorded customer funding of product engineering and development identified as material rights as current and noncurrent deferred revenue contract liabilities included in “Accrued liabilities” and “Other liabilities.” The related customer funded product engineering and development costs were capitalized as costs to fulfill a contract, to the extent of the contractually committed customer funded payments, and are recorded as “Other assets.”

Operations and Summary of Significant Accounting Policies
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 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, wind turbines, including converters and power grid related equipment, industrial diesel, gas, bio-diesel 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. 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 $ 1,018 in fiscal year 2019, and $ 1,608 in fiscal year 2018, and $ 651 in fiscal year 2017. Revenue recognition : Effective October 1, 2018, Woodward adopted the new revenue recognition guidance of ASC 606. For discussion of the impacts of the adoption of ASC 606 on our revenue recognition policy and related critical accounting estimates, see Note 3, 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. Cash and cash equivalents are maintained with multiple financial institutions. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. Woodward holds cash and cash equivalents at financial institutions in excess of amounts covered by the Federal Depository Insurance Corporation (the “FDIC”), sometimes invests excess cash in money market funds or other highly liquid investments not insured by the FDIC, and holds cash and cash equivalents outside the United States that are not insured by the FDIC. 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, and current economic conditions. 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. Consistent with common business practice in China, Woodward’s Chinese subsidiary accepts from Chinese customers, in settlement of certain customer accounts receivable, bankers’ acceptance notes issued by Chinese banks that are believed to be creditworthy. 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. The issuing financial institution is the obligor, not Woodward’s customers. Upon Woodward’s acceptance of a banker’s acceptance note from a customer, such customer has no further obligation to pay Woodward for the related accounts receivable balance. Woodward only accepts bankers’ acceptance notes issued by banks that are believed to be creditworthy and to which the credit risks associated with the bankers’ acceptance notes are believed to be minimal. For discussion of the impacts of the adoption of ASC 606 on our accounts receivable policy and 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. For discussion of Woodward’s accounting policy for inventory provided by customers to Woodward, which will be integrated into final products sold to those customers, see Note 3, Revenue. 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, 2019 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 year s to five year s. Purchase accounting: Business combinations are accounted for using the purchase method of accounting. Under the purchase method, assets and liabilities, including intangible assets, are recorded at their fair values as of the acquisition date. Acquisition costs in excess of amounts assigned to assets acquired and liabilities assumed are recorded as goodwill. Transaction-related costs associated with business combinations are expensed as 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 tests consist 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 goodwill impairment testing it has recorded no impairment charges in the year ended September 30, 2019 or since the goodwill was originally recognized. 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 amortizable 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. Amortizable 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, 2019 or since the other intangibles were originally recorded. Estimated lives over which intangible assets are amortized at September 30, 2019 were as follows: Backlog 1 year Customer relationships and contracts 9 - 30 years Intellectual property 10 - 17 years Process technology 8 - 30 years Other 3 - 15 years Woodward has one other indefinitely lived intangible asset consisting of the Woodward L’Orange tradename. The Woodward L’Orange tradename 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 tradename 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. Based on the results of the Woodward L’Orange impairment testing, it has recorded no impairment charges in the year ended September 30, 2019 or since the intangible asset was originally recognized. 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 groups carrying amount and its estimated fair value. There were no impairment charges recorded in fiscal years 2019, 2018 or 2017. 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.” 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. To mitigate interest rate risk, the Company has utilized derivative instruments, such as treasury lock agreements to lock in fixed rates on future debt issuances, which qualify as cash flow or fair value hedges to mitigate the risk of variability in cash flows related to future interest payments attributable to changes in the designated benchmark rate. The Company records all such interest rate hedge instruments on the Consolidated Balance Sheets at fair value. Cash flows related to the instrument designated as a qualifying hedge are reflected in the accompanying Consolidated Statements of Cash Flows in the same categories as the cash flows from the items being hedged. Accordingly, cash flows relating to the settlement of interest rate derivatives hedging the forecasted future interest payments on debt have been reflected upon settlement as a component of financing cash flows. The resulting gain or loss from such settlement is deferred to other comprehensive income and reclassified to interest expense over the term of the underlying debt. This reclassification of the deferred gains and losses impacts the interest expense recognized on the underlying debt that was hedged and is therefore reflected as a component of operating cash flows in periods subsequent to settlement. The periodic settlement of interest rate derivatives hedging outstanding variable rate debt is recorded as an adjustment to interest expense and is therefore reflected as a component of operating cash flows. 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 the spot remeasurement its Euro denominated intercompany loans, Woodward has entered into derivative instruments in fair value hedging relationships, and derivative instruments in cash flow hedging relationships 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 its Euro denominated intercompany loans. 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 . 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. The fair value of investments in the deferred compensation program are adjusted to fair value based on the quoted market prices for the investments in the various mutual funds owned. The fair value of the long-term notes from municipalities are estimated based on a model that discounts future principal and interest payments received at interest rates available to the Company at the end of the period for similarly rated municipal notes of similar maturity. The fair value of term deposits are estimated based on a model that discounts future principal and interest payments received at interest rates available to the Company at the end of the period for similar term deposits with the same maturity in the same jurisdictions. The fair value of the 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. The fair value of long-term debt is estimated based on a model that discounts future principal and interest payments at interest rates available to the Company at the end of the period for similar debt with the same maturity. Further information on the fair value of financial instruments can be found at Note 7, Financial instruments and fair value measurements . 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. 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. Reclassifications: Certain amounts at the Consolidated Balance Sheet as of September 30, 2018 and the Consolidated Statement of Cash Flows for the years ended September 30, 2018 and 2017 have been reclassified in order to conform to the current year presentation under ASU 2014-09, “Revenue from Contracts with Customers” (see Note 3, Revenue ) . Certain amounts at the Consolidated Statement of Earnings for the fiscal years ended September 30, 2018 and September 30, 2017 have been reclassified in order to conform to the current year presentation under ASU 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (see Note 2, New accounting standards ).

New Accounting Standards

New Accounting Standards	12 Months Ended

New Accounting Standards
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”). In August 2019, the FASB issued ASU 2019-08, “Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Codification Improvements—Share-Based Consideration Payable to a Customer.” This ASU clarifies or improves the disclosure and presentation requirements of a variety of Codification Topics by aligning them with the SEC’s regulations, eliminating redundancies, and making the Codification easier to apply. Woodward adopted in the fourth quarter of fiscal year 2019 to incorporate the simplification in disclosures. Upon adoption, there was no material impact to the Consolidated Financial Statements and related disclosures. In July 2019, the FASB issued ASU 2019-07, “Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10532, Disclosure Update and Simplification, and Nos. 33-10231 and 33-10442, Investment Company Reporting Modernization, and Miscellaneous Updates.” This ASU clarifies or improves the disclosure and presentation requirements of a variety of Codification Topics by aligning them with the SEC’s regulations, eliminating redundancies, and making the Codification easier to apply. Woodward adopted in the fourth quarter of fiscal year 2019 to incorporate the simplification in disclosures. Upon adoption, there was no material impact to the Consolidated Financial Statements and related disclosures. In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Topic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans.” ASU 2018-14 amends ASC 715 to add, remove, and modify disclosure requirements related to defined benefit pension and other postretirement plans. The ASU’s changes to disclosures aim to improve the effectiveness of ASC 715’s disclosure requirements under the FASB’s disclosure framework project. ASU 2018-14 is effective for public entities for fiscal years beginning after December 15, 2020 (fiscal year 2022 for Woodward). ASU 2018-14 does not impact the interim disclosure requirements of ASC 715. Upon adoption, the amendments in ASU 2018-14 should be applied on a retrospective basis to all periods presented. Early adoption is permitted. Woodward expects to adopt the new and modified disclosures requirements of this new guidance in fiscal year 2022. In February 2018, the FASB issued ASU 2018-02, “Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of tax reform under H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the “Tax Act”) (also known as “The Tax Cuts and Jobs Act”), and provides guidance on the disclosure requirements regarding the stranded tax effects. The amendments in ASU 2018-02 are effective for all entities for fiscal years beginning after December 15, 2018 (fiscal year 2020 for Woodward), and interim periods within those fiscal years. Early adoption is permitted. The amendments in ASU 2018-02 may be applied retrospectively in the period of adoption to all periods in which the effect of the change in the United States (“U.S.”) federal corporate income tax rate in the Tax Act is recognized or may be applied as of the beginning of the period of adoption. Woodward is currently assessing the impact of the adoption of the new guidance and has not yet elected the method of adoption it will apply. Woodward expects to adopt the new guidance under ASU 2018-02 in fiscal year 2020. Upon adoption, if Woodward elects to reclassify under ASU 2018-02, a portion of accumulated other comprehensive earnings would be reclassified to retained earnings. In March 2017, the FASB issued ASU 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” ASU 2017-07 requires that the service cost component of net periodic benefit costs from defined benefit and other postretirement benefit plans be included in the same statement of earnings captions as other compensation costs arising from services rendered by the covered employees during the period. The other components of net benefit cost are presented in the statement of earnings separately from service costs. ASU 2017-07 is effective for fiscal years beginning after December 31, 2017 (fiscal year 2019 for Woodward). Following adoption, only service costs will be eligible for capitalization into manufactured inventories, which should reduce diversity in practice. The amendments of ASU 2017-07 must be applied retrospectively for the presentation of the service cost component and the other components of net periodic benefit costs from defined benefit and other postretirement benefit plans in the statement of earnings and prospectively, on and after the effective date, for the capitalization of the service cost component into manufactured inventories. Woodward adopted the new guidance effective October 1, 2018 and concluded it had no impact on net earnings. As a result of the adoption of ASU 2017-07, only the service component of net periodic benefit costs from defined benefit and other postretirement benefit plans are included in cost of goods sold and selling, general and administrative expenses. All other net periodic benefit costs, other than interest cost, are included in other expense (income), net. The interest cost component of net periodic benefit costs is included in interest expense as Woodward believes it is more similar to the elements within interest expense than other expense (income), net, which combines several elements that are heterogeneous (see Note 17, Other (income) expense, net ), thus improving consistency for users of the financial statements. The following table shows the impact of retrospectively applying this guidance to the Consolidated Statement of Earnings for the fiscal years ended September 30, 2018 and September 30, 2017. Year Ended September 30, 2018 Year Ended September 30, 2017 As previously reported Adjustment As recast As previously reported Adjustment As recast Net sales $ 2,325,873 $ - $ 2,325,873 $ 2,098,685 $ - $ 2,098,685 Costs and expenses: Cost of goods sold 1,719,675 3,127 1,722,802 1,526,126 1,442 1,527,568 Selling, general, and administrative expenses 192,757 979 193,736 176,633 689 177,322 Research and development costs 148,279 - 148,279 126,519 - 126,519 Restructuring charges 17,013 - 17,013 - - - Interest expense 31,770 8,695 40,465 27,430 8,209 35,639 Interest income ( 1,674 ) - ( 1,674 ) ( 1,725 ) - ( 1,725 ) Other (income) expense, net ( 1,525 ) ( 12,801 ) ( 14,326 ) ( 9,045 ) ( 10,340 ) ( 19,385 ) Total costs and expenses 2,106,295 - 2,106,295 1,845,938 - 1,845,938 Earnings before income taxes 219,578 - 219,578 252,747 - 252,747 Income tax expense 39,200 - 39,200 52,240 - 52,240 Net earnings $ 180,378 $ - $ 180,378 $ 200,507 $ - $ 200,507 In October 2016, the FASB issued ASU 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory.” ASU 2016-16 eliminates the current U.S. GAAP exception deferring the tax effects of intercompany asset transfers (other than inventory) until the transferred asset is sold to a third party or otherwise recovered through use. ASU 2016-16 is effective for fiscal years beginning after December 15, 2017 (fiscal year 2019 for Woodward), including interim periods within the year of adoption. Woodward adopted the new guidance on October 1, 2018. Modified retrospective adoption is required with any cumulative-effect adjustment recorded to retained earnings as of the beginning of the period of adoption. The cumulative impact of the adoption of ASU 2016-16 of $ 1,005 was recognized at the date of adoption as a decrease to both retained earnings and other current assets in the Consolidated Balance Sheet. As a result of adoption, Woodward will recognize the tax consequences of intercompany asset transfers in the buyer’s and seller’s tax jurisdictions when the transfer occurs, even though the pre-tax effects of these transactions are eliminated in consolidation. In June 2016, the FASB issued ASU 2016-13, “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. Early adoption is permitted for fiscal years beginning after December 15, 2018 (fiscal year 2020 for Woodward), including interim periods within those fiscal years. Woodward expects to adopt ASU 2016-13 in fiscal year 2021. Woodward does not expect the application of the CECL impairment model to have a significant impact on Woodward’s allowance for uncollectible amounts for accounts receivable, and the valuation of notes receivable from municipalities and unbilled receivables. In May 2019, the FASB issued ASU 2019-05, “Financial Instruments – Credit Losses (Topic 326): Targeted Transition Relief,” which provides transition relief for entities adopting ASU 2016-13. Specifically, ASU 2019-05 amends ASU 2016-13 to allow companies to irrevocably elect, upon adoption of ASU 2016-13, the fair value option for financial instruments that (i) were previously recorded at amortized cost and are within the scope of the credit losses guidance in ASC 326-20, (ii) are eligible for the fair value option under ASC 825-10, and (iii) are not held-to-maturity debt securities. For entities that have adopted ASU 2016-13, the amendments in ASU 2019-05 are effective for fiscal years beginning after December 15, 2019, including interim periods therein. An entity may early adopt the ASU in any interim period after its issuance if the entity has adopted ASU 2016-13. For all other entities, the effective date will be the same as the effective date of ASU 2016-13. Woodward expects to adopt ASU 2019-05 in fiscal year 2021. Woodward does not expect to elect the fair value option for its financial instruments upon the adoption of both ASU 2016-13 and ASU 2019-05. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) Targeted Improvements,” (collectively with ASU 2016-02, “ASC 842”) which amends ASU 2016-02 to provide organizations with a new (and optional) transition method permitting the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption, rather than requiring retrospective restatement of prior periods. The purpose of ASC 842 is to increase transparency and comparability among organizations by recognizing lease right-of-use (“ROU”) assets and lease liabilities except for short-term leases on the balance sheet, and provide additional disclosure information about leasing arrangements. ASC 842 modifies the definition of a lease to clarify that an arrangement contains a lease when such arrangement conveys the right to control the use of an identified asset. ASC 842 is effective for fiscal years beginning after December 15, 2018 (fiscal year 2020 for Woodward), including interim periods within the year of adoption. Woodward will adopt ASC 842 on October 1, 2019, the first day of fiscal year 2020. Originally under ASC 842, an organization was required upon adoption to recognize and measure leases beginning in the earliest period presented using a modified retrospective approach and restate the financial statements for all periods presented. Woodward expects to elect the new transition method resulting in a cumulative-effect adjustment to retained earnings on October 1, 2019. Woodward is currently assessing the impact this guidance will have on its Consolidated Financial Statements, including which of its existing lease arrangements will be impacted by the new guidance. In anticipation of adopting ASC 842 on October 1, 2019, Woodward has developed a comprehensive project plan, established a cross-functional global project team, and engaged third-party subject matter experts. The project plan includes reviewing various forms of leases, analyzing the optional practical expedients available in ASC 842, and updating Woodward’s business processes and controls to meet the requirements of ASU 2016-02, as necessary. Woodward expects the most significant effects of the adoption of ASC 842 will be the recognition of operating lease ROU assets and lease liabilities on its balance sheets and changes to the accounting for the Company’s loss reserve on contractual lease commitments. Rent expense for all operating leases in fiscal year 2019, none of which was recognized on the balance sheet, was $ 7,578 . As of September 30, 2019, future minimum rental payments required under operating leases, none of which were recognized on the balance sheet, were $ 26,919 .

Revenue	Note 3. Revenue Adoption of ASC 606 In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” and has subsequently issued several supplemental and/or clarifying ASUs (collectively “ASC 606”). ASC 606 prescribes a single common revenue standard that replaces most existing U.S. GAAP revenue recognition guidance. Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The results for periods prior to fiscal year 2019 were not adjusted for the new standard and the cumulative effect of the change in accounting of $ 38,745 was recognized as a net increase to retained earnings at the date of adoption. Woodward has elected to apply the modified retrospective method only to contracts that were not completed as of October 1, 2018. As a practical expedient under ASC 606, Woodward elected to reflect the aggregate effect of all modifications that occurred before the beginning of fiscal year 2019 to contracts for which Woodward had not recognized all revenue as of October 1, 2018 as part of the adjustment to retained earnings at the date of adoption. Revenue Recognition Policy Revenue is recognized on contracts with Woodward’s 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. A performance obligation is a promise in a contract with a customer to transfer a distinct product or service to the customer. 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 distinct 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. Woodward’s contracts with customers generally do not include a financing component. Woodward regularly reviews its estimates of variable consideration on the transaction price and recognizes changes in estimates on a cumulative catch-up basis as if the most current estimate of the transaction price adjusted for variable consideration had been known as of the inception of the contract. In the fiscal year ended September 30, 2019, Woodward did not recognize a significant amount of revenue due to changes in transaction price from performance obligations that were satisfied, or partially satisfied, in prior periods. 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. Woodward recognized revenue of $ 98,061 for the fiscal year 2019, related to noncash consideration received from customers. The Aerospace segment recognized $ 96,762 for the fiscal year ended September 30, 2019, while the Industrial segment recognized $ 1,299 for the fiscal year ended September 30, 2019. Sales of Products Woodward primarily generates revenue through the manufacture and sale of engineered aerospace and industrial products, including revenue derived from maintenance, repair and overhaul (“MRO”) performance obligations performed on products originally manufactured by Woodward and subsequently returned by original equipment manufacturer (“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. Revenue from manufactured and MRO products represented 86 % and 12 %, respectively, of Woodward’s net sales for the fiscal year ended September 30, 2019. Many Woodward products include embedded software or firmware that is critical to the performance of the product as designed. As the embedded software or firmware is essential to the functioning of the products sold it does not represent a distinct performance obligation separate from the related tangible product in which the software or firmware is embedded. Woodward does not generally sell or license software or firmware on a standalone basis. Software or firmware upgrades, if any, are generally paid for by the customer and treated as separate performance obligations. The products Woodward sells generally are not subject to risk of return, refund or other similar obligations. Woodward’s sales include product warranty arrangements with customers which are generally assurance-type warranties, rather than service-type warranties. Accordingly, Woodward accounts for warranty related promises to its customers as a guarantee for which a warranty liability is recorded when the related product or service is sold, rather than as a distinct performance obligation accounted for separately from the sale of the underlying product or service. Warranty liabilities are accrued for based on specifically identified warranty issues that are probable to result in future costs, or on a non-specific basis whenever past experience indicates that a normal and predictable pattern exists. Revenue from shipping and handling activities charged to customers are included in net sales when invoiced to the customer and the related costs are included in cost of goods sold. As a practical expedient under ASC 606, Woodward has elected to account for the costs of shipping and handling activities as a cost to fulfill a contract and not a promised product or service. Shipping and handling costs relating to the sale of products recognized at a point in time are recognized as incurred. Shipping and handling costs relating to the sale of products or services recognized over time are accrued and recognized during the earnings process. 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. As of September 30, 2019, other assets included $ 105,206 of capitalized costs to fulfill contracts with customers. 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. For the fiscal year ended September 30, 2019, Woodward recognized an increase in revenue of $ 6,017 , and cost of goods sold of $ 9,580 , related to changes in estimated total lifetime sales. Other than amounts related to changes in estimate, for the fiscal year ended September 30, 2019, Woodward amortized $ 376 of costs to fulfill contracts with customers to cost of goods sold and amortized $ 719 of contract liabilities to revenue. In 2016, Woodward contributed certain contractual rights and intellectual property to a joint venture with the General Electric Company (“GE”). In exchange for a 50 % ownership interest in the joint venture and future rights to purchase products from the joint venture at favorable pricing, GE agreed to pay total consideration of $ 323,410 to Woodward. Under previous accounting guidance, Woodward concluded that the formation of the joint venture was not the culmination of an earnings event and deferred recognition of the consideration paid until earned in the future. Under ASC 606, Woodward also concluded that the formation of the joint venture was not a culmination of an earnings event and has further concluded that the consideration paid or receivable from GE represents a material right. Accordingly, under both ASC 606 and the previous standard, Woodward concluded it was appropriate to defer the consideration received as a liability and recognized it as an increase to net sales in proportion to revenue realized on sales of applicable fuel systems within the scope of the joint venture. Recognition to net sales in a particular period is determined as a percentage of total revenue expected to be realized by Woodward over the estimated remaining lives of the underlying commercial aircraft engine programs assigned to the joint venture. As of the adoption of ASC 606, Woodward has classified this as a contract liability with both a current and noncurrent portion. For further discussion of Woodward’s joint venture, see Note 6, Joint venture . Woodward does not record 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 . Point in time and over time revenue recognition Approximately one-half of Woodward’s customer contracts are recognized at the point in time when control of the products transfers to the customer, generally upon shipment of products, consistent with Woodward’s historical revenue recognition model. The remaining portion of Woodward’s revenues from sales of products and services to customers is recognized over time, rather than at a point in time, due primarily to the terms of certain customer contracts and/or the type of performance obligation being satisfied, as described below. The following table reflects the amount of revenue recognized as point in time or over time for the fiscal year ended September 30, 2019: Year Ended September 30, 2019 Aerospace Industrial Consolidated Point in time $ 762,042 $ 634,219 $ 1,396,261 Over time 1,118,478 385,458 1,503,936 Total net sales $ 1,880,520 $ 1,019,677 $ 2,900,197 Point in time 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. Woodward exercises judgment and considers the timing of right of payment, transfer of the risk and rewards, transfers of title, transfer of physical possession, and customer acceptance when determining when control of the product transfers to the customer, generally upon shipment of products, consistent with Woodward’s historical revenue recognition model. Over time 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 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. As a practical expedient, revenue for services that are short-term in nature are recognized using an output method as the customer is invoiced, as the invoiced amount corresponds directly to Woodward’s performance to date on the arrangement. 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. A change in one or more of these estimates could affect the timing of revenue recognition on these contracts. Woodward reviews and updates its cost estimates regularly. Due to uncertainties inherent in the estimation process, it is reasonably possible that completion costs may be different than those estimated. Such changes in cost estimates and the related impact on the revenue recognized in the period in which the revisions are determined is recorded as a cumulative catch-up adjustment. The production of products and MRO activities are generally shorter-term in nature and therefore, the impacts of changes in estimates for these costs are considered immaterial. 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. 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. 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. Unbilled amounts 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 amounts 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 amounts 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. Accounts receivable consisted of the following: September 30, 2019 September 30, 2018 Billed receivables Trade accounts receivable $ 381,942 $ 403,590 Other (Chinese financial institutions) 42,171 23,191 Less: Allowance for uncollectible amounts ( 7,908 ) ( 3,938 ) Net billed accounts receivable 416,205 422,843 Current unbilled receivables (contract assets), net 175,324 9,160 Total accounts receivable, net $ 591,529 $ 432,003 As of the October 1, 2018 adoption of ASC 606, Woodward recognized unbilled receivables of $ 135,668 . The remaining change in unbilled receivables was driven by the timing of revenue recognized in excess of billings, primarily in Woodward’s Aerospace segment. In addition, as of September 30, 2019 “Other assets” on the Consolidated Balance Sheets includes $ 1,573 of unbilled receivables not expected to be invoiced and collected within a period of twelve months. As of September 30, 2018, there were $ 763 unbilled receivables not expected to be invoiced and collected within a period of twelve months. Customer billed receivables are recorded at face amounts, less an allowance for doubtful accounts. 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, and current economic conditions. 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. In the fiscal year ended September 30, 2019, receivables written off were immaterial. An 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. Changes to this allowance are recorded as increases or decreases to net sales as adjustments to the transaction price related to variable consideration. In establishing this amount, both customer-specific information and historical experience are considered. Unbilled receivables are stated net of adjustments for credit risk and the anticipated impacts of variable consideration on the transaction price, as applicable. Billed and unbilled accounts receivable from the U.S. Government were less than 10 % of total billed and unbilled accounts receivable at September 30, 2019. 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 derecognized 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. The current portion is included in “Accrued liabilities” and the noncurrent portion is included in “Other liabilities” at Woodward’s Consolidated Balance Sheets. Contract liabilities consisted of the following: September 30, 2019 September 30, 2018 Current Noncurrent Current Noncurrent Deferred revenue from material rights from GE joint venture formation $ 8,317 $ 230,588 $ 7,087 $ 235,300 Deferred revenue from advance invoicing and/or prepayments from customers 4,554 141 2,572 - Liability related to customer supplied inventory 13,396 - - - Deferred revenue from material rights related to engineering and development funding 1,624 106,436 - - Net contract liabilities $ 27,891 $ 337,165 $ 9,659 $ 235,300 As of the October 1, 2018 adoption of ASC 606, Woodward recognized current liabilities for the noncash consideration provided to Woodward in the form of customer supplied inventory of $ 11,951 and current and noncurrent liabilities for deferred revenue from material rights related to engineering and development funding of $ 664 and $ 79,347 , respectively. All other changes in contract liability balances were due to normal operating activities. Woodward recognized revenue of $ 21,658 in the fiscal year ended September 30, 2019 from contract liabilities balances recorded as of October 1, 2018. 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, 2019 was $ 1,527,437 , the majority of which relate to Woodward’s Aerospace segment. Woodward expects to recognize almost all of these remaining performance obligations within two year s after September 30, 2019. Firm orders for which the Company does not expect to recognize future revenue due to credit risk of the customer are excluded from the amount of remaining performance obligations. Remaining performance obligations related to material rights that have not yet been recognized in revenue as of September 30, 2019 was $ 424,773 , of which $ 11,119 is expected to be recognized in fiscal year 2020 , 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 year s. Financial statement impact of the adoption of ASC 606 T he following schedule quantifies the impact of adopting ASC 606 on the Consolidated Balance Sheet as of October 1, 2018.

The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory. (2) The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.” (3) Woodward recorded customer funding of product engineering and development identified as material rights as current and noncurrent deferred revenue contract liabilities included in “Accrued liabilities” and “Other liabilities.” The related customer funded product engineering and development costs were capitalized as costs to fulfill a contract, to the extent of the contractually committed customer funded payments, and are recorded as “Other assets.” (4) The net book value of the backlog and customer relationships and contracts intangible assets was adjusted concurrent with the change in the timing of the associated revenue, resulting in a reduction in the net book value of these assets as of the date of adoption. (5) The value of tax assets and tax liabilities was impacted by the change in timing of the recognition of assets and liabilities within tax jurisdictions. T he following schedule quantifies the impact of adopting ASC 606 on the Consolidated Statements of Earnings for the fiscal year ended September 30, 2019. The effect of the new standard represent the increase (decrease) in the line item based on the adoption of ASC 606.

The increases were offset by decreases in revenue and cost of goods sold related to the deferral of amounts due from customers recognized as material rights and over time contracts recognized as of the date of adoption, both of which would otherwise have been recognized as revenue during the periods under the previous standard. The following schedule quantifies the impact of adopting ASC 606 on the Consolidated Balance Sheet as of September 30, 2019.

Earnings Per Share
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, 2019 2018 2017 Numerator: Net earnings $ 259,602 $ 180,378 $ 200,507 Denominator: Basic shares outstanding 61,950 61,493 61,366 Dilutive effect of stock options and restricted stock units 2,548 2,383 2,146 Diluted shares outstanding 64,498 63,876 63,512 Income per common share: Basic earnings per share $ 4.19 $ 2.93 $ 3.27 Diluted earnings per share $ 4.02 $ 2.82 $ 3.16 The following stock option grants were outstanding during the fiscal years ended September 30, 2019, 2018 and 2017, but were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive.

Business Acquisition
Business Acquisition	Note 5. Business acquisition In fiscal year 2018, the Company, and its wholly-owned subsidiary, Woodward Aken GmbH (collectively, the “Purchasers”), entered into a Share Purchase Agreement (the “L’Orange Agreement”) with MTU Friedrichshafen GmbH (“MTU”) and MTU America Inc. (together with MTU, the “Sellers”), both of which were subsidiaries of Rolls-Royce PLC (“Rolls-Royce”). Pursuant to the L’Orange Agreement, the Purchasers agreed to acquire all of the outstanding shares of stock of L’Orange GmbH, together with its wholly-owned subsidiaries in China and Germany, as well as all of the outstanding equity interests of its affiliate, Fluid Mechanics LLC, and their related operations (collectively, “L’Orange”), for total consideration (including cash consideration and the assumption of certain liabilities) of € 700,000 , or approximately $ 811,000 based on the foreign currency exchange rate as of the date Woodward executed cross currency swaps in connection with the financing of the transaction as described in Note 8, Derivative instruments and hedging activities . The transactions contemplated by the L’Orange Agreement were completed on June 1, 2018 (the “Closing”) and L’Orange became a subsidiary of the Company. Following the Closing, L’Orange was renamed “Woodward L’Orange.” In connection with the Closing, MTU and a subsidiary of Rolls-Royce, and Woodward L’Orange, entered into a long-term supply agreement, dated June 1, 2018 (the “LTSA”). Pursuant to the terms of the LTSA, Woodward L’Orange will continue to supply to MTU and its affiliates within Rolls-Royce certain liquid fuel injection systems, injectors, pumps and other associated parts and components for industrial diesel, heavy fuel oil and dual-fuel engines in a manner consistent with the supply of such products prior to the transaction. The LTSA has an initial term that extends through December 31, 2032. During the term of the LTSA, MTU will continue to purchase certain of these products exclusively from Woodward L’Orange, subject to certain limitations specified therein, at pricing negotiated at arms-length. ASC Topic 805, “Business Combinations” (“ASC 805”), provides a framework to account for acquisition transactions under U.S. GAAP. The purchase price of L’Orange, prepared consistent with the required ASC 805 framework, is allocated as follows: Cash paid to Sellers $ 780,401 Less acquired cash and restricted cash ( 9,286 ) Total purchase price $ 771,115 The cash consideration was financed through the use of cash on hand, the issuance of an aggregate principal amount of $ 400,000 of senior unsecured notes in a series of private placement transactions and $ 167,420 borrowed under Woodward’s revolving credit agreement (see Note 14, Credit facilities, short-term borrowings and long-term debt ). In connection with these borrowings, the Company entered into cross currency swap transactions, which effectively lowered the interest rate on each tranche of the senior unsecured notes and the borrowings under the Company’s revolving credit agreement (see Note 8, Derivative instruments and hedging activities ). The allocation of the purchase price to the assets acquired and liabilities assumed was finalized as of June 30, 2019 using the purchase method of accounting in accordance with ASC 805. Assets acquired and liabilities assumed in the transaction were recorded at their acquisition date fair values, while transaction costs associated with the acquisition were expensed as incurred. Woodward’s allocation was based on an evaluation of the appropriate fair values and represents management’s best estimate based on available data. The following table, which is final as of June 30, 2019, summarizes the estimated fair values of the assets acquired and liabilities assumed at the Closing. Accounts receivable $ 26,538 Inventories (1) 72,392 Other current assets 1,385 Property, plant, and equipment 89,772 Goodwill 257,447 Intangible assets 573,427 Total assets acquired 1,020,961 Other current liabilities 41,997 Deferred income tax liabilities 166,927 Other noncurrent liabilities 40,922 Total liabilities assumed 249,846 Net assets acquired $ 771,115 (1) Inventories include a $ 16,324 adjustment to state work in progress and finished goods inventories at their fair value as of the acquisition date. The entire inventory fair value adjustment was recognized as a noncash increase to cost of goods sold ratably over the estimated inventory turnover period during the fiscal year ended September 30, 2018 . The final purchase price allocation resulted in the recognition of $ 257,447 of goodwill. Only the portion of goodwill which relates to the U.S. operations of Woodward L’Orange is deductible for tax purposes. The Company has included all of the goodwill in its Industrial segment. The goodwill represents the estimated value of potential expansion with new customers, the opportunity to further develop sales opportunities with new customers, other synergies including supply chain savings expected to be achieved through the integration of Woodward L’Orange with Woodward’s Industrial segment, and intangible assets that do not qualify for separate recognition, such as the value of the assembled Woodward L’Orange workforce that is not included within the estimated value of the acquired backlog and customer relationship intangible assets. In connection with the acquisition of L’Orange, Woodward assumed the defined benefit pension obligations of the L’Orange defined benefit pension plans (the “Woodward L’Orange Pension Plans”). Woodward’s assumption of the liability associated with the Woodward L’Orange Pension Plans was part of the total consideration paid by Woodward to acquire L’Orange and thus reduced Woodward’s cash payment for the transaction. As of the Closing, the total liability recognized by the Company associated with the Woodward L’Orange Pension Plans was $ 39,257 , of which $ 1,143 was considered current. A summary of the intangible assets acquired, weighted-average useful lives, and amortization methods follows: Estimated Amounts Weighted-Average Useful Life Amortization Method Intangible assets with finite lives: Customer relationships and contracts $ 388,705 22 years Straight-line Process technology 74,260 22 years Straight-line Backlog 42,932 1 year Accelerated Other 232 3 years Straight-line Intangible asset with indefinite life: Trade name 67,298 Indefinite Not amortized Total $ 573,427 Pro forma results for Woodward giving effect to the L’Orange acquisition The following unaudited pro forma financial information presents the combined results of operations of Woodward and Woodward L’Orange as if the acquisition had been completed as of the beginning of the fiscal year prior to the year the acquisition took place, or October 1, 2016. The unaudited pro forma financial information is presented for informational purposes and is not indicative of the results of operations that would have been achieved if the acquisition and related borrowings had taken place on October 1, 2016, nor are they indicative of future results. The unaudited pro forma financial information for the fiscal year ended September 30, 2019 includes Woodward’s results, including the post-acquisition results of Woodward L’Orange, since June 1, 2018. The unaudited pro forma financial information for the fiscal year ended September 30, 2018 combines Woodward’s results with the pre-acquisition results of L’Orange for the period prior to June 1, 2018, and the post-acquisition results of Woodward L’Orange since June 1, 2018. The unaudited pro forma financial information for the fiscal year ended September 30, 2017 combines Woodward’s results with the pre-acquisition results of Woodward L’Orange for that period. Prior to the L’Orange acquisition by Woodward, L’Orange was a wholly owned subsidiary of Rolls-Royce, and as such was not a standalone entity for financial reporting purposes. Accordingly, the historical operating results of L’Orange may not be indicative of the results that might have been achieved, historically or in the future, if L’Orange had been a standalone entity. The unaudited pro forma results for fiscal years ended September 30, 2019, September 30, 2018 and September 30, 2017 are as follows: Year Ended Year Ended Year Ended September 30, 2019 September 30, 2018 September 30, 2017 As reported Pro forma As reported Pro forma As reported Pro forma Net sales $ 2,900,197 $ 2,900,197 $ 2,325,873 $ 2,549,874 $ 2,098,685 $ 2,380,572 Net earnings 259,602 267,649 180,378 225,800 200,507 179,220 Earnings per share: Basic earnings per share $ 4.19 $ 4.32 $ 2.93 $ 3.67 $ 3.27 $ 2.92 Diluted earnings per share 4.02 4.15 2.82 3.53 3.16 2.82 The unaudited pro forma results for all periods presented include adjustments made to account for certain costs and transactions that would have been incurred had the acquisition been completed as of October 1, 2016, including amortization charges for acquired intangible assets, eliminations of intercompany transactions, adjustments for acquisition transaction costs, adjustments for depreciation expense for property, plant, and equipment, and adjustments to interest expense. These adjustments are net of any applicable tax impact and were included to arrive at the pro forma results above. The operating results of Woodward L’Orange have been included in Woodward’s operating results for the periods subsequent to the completion of the acquisition on June 1, 2018. Woodward L’Orange contributed net sales of $ 332,009 for the fiscal year ended September 30, 2019, and net sales of $ 102,905 for the fiscal year ended September 30, 2018. Woodward L’Orange contributed net income before income taxes of $ 47,246 for the fiscal year ended September 30, 2019, and a net loss before income taxes of $ 9,334 for the fiscal year ended September 30, 2018. Woodward incurred acquisition financing related costs of $ 14,823 for the fiscal year ended September 30, 2019 as compared to $ 4,904 for the fiscal year ended September 30, 2018. The acquisition financing related costs are included in “Interest expense” in the Consolidated Statements of Earnings.

Joint Venture

Joint Venture
Joint Venture	Note 6. Joint venture On January 4, 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. As part of the JV formation, Woodward contributed to the JV certain contractual rights and intellectual property applicable to the existing GE commercial aircraft engine programs within the scope of the JV. Woodward had no initial cost basis in the JV because Woodward had no cost basis in the contractual rights and intellectual property contributed to the JV. GE purchased from Woodward a 50 % ownership interest in the JV for a $ 250,000 cash payment to Woodward. In addition, GE will pay contingent consideration to Woodward consisting of fifteen annual payments of $ 4,894 per year, which began on January 4, 2017, subject to certain claw-back conditions. During the second quarter of the fiscal years ended September 30, 2019 and September 30, 2018, Woodward received its second and third annual payments of $ 4,894 , 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. Under previous accounting guidance, Woodward concluded that the formation of the JV was not the culmination of an earnings event and deferred recognition of the consideration paid until earned in the future. Under ASC 606, Woodward also concluded the formation of the JV was not a culmination of an earnings event and has further concluded that the consideration paid or receivable from GE represents a material right. Accordingly, under both ASC 606 and the previous standard, Woodward concluded it was appropriate to defer the consideration received as a liability and recognize it as an increase to net sales in proportion to revenue realized on sales of applicable fuel systems within the scope of the JV. Recognition to net sales in a particular period is determined as a percentage of total revenue expected to be realized by Woodward over the estimated remaining lives of the underlying commercial aircraft engine programs assigned to the JV. Unamortized deferred revenue from material rights in connection with the JV formation included accrued liabilities of $ 8,317 as of September 30, 2019 and $ 7,087 as of September 30, 2018, and other liabilities of $ 230,588 as of September 30, 2019 and $ 235,300 as of September 30, 2018. Amortization of the deferred income (material right) recognized as an increase to sales was $ 7,652 for the twelve months ended September 30, 2019, $ 5,854 for the twelve months ended September 30, 2018, and $ 6,286 for the twelve months ended September 30, 2017. 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. Other income includes income of $ 12,932 for the fiscal year ended September 30, 2019, income of $ 3,339 for the fiscal year ended September 30, 2018, and income of $ 2,568 for the fiscal year ended September 30, 2017 related to Woodward’s equity interest in the earnings of the JV. During the twelve months ended September 30, 2019, Woodward received cash distributions from the JV of $ 15,000 , which is included in Net cash provided by operating activities on the Consolidated Statements of Cash Flows. Woodward received no cash distributions from the JV during the fiscal year ended September 30, 2018, and $ 2,500 cash distribution from the JV during the fiscal year ended September 30, 2017. Woodward’s net investment in the JV, which is included in other assets, was $ 7,543 as of September 30, 2019 and $ 9,611 as of September 30, 2018. Woodward’s net sales include $ 60,955 for the fiscal year ended September 30, 2019 of sales to the JV, compared to $ 72,511 for the fiscal year ended September 30, 2018, and $ 70,234 for the fiscal year ended September 30, 2017. Woodward recorded a reduction to sales of $ 34,236 for the fiscal year ended September 30, 2019 related to royalties paid to the JV by Woodward on sales by Woodward directly to third party aftermarket customers , compared to $ 26,023 for the fiscal year ended September 30, 2018 and $ 26,133 for the fiscal year ended September 30, 2017. The Consolidated Balance Sheets include “Accounts receivable” of $ 5,906 at September 30, 2019, and $ 10,499 at September 30, 2018, related to amounts the JV owed Woodward, and include “Accounts payable” of $ 4,270 at September 30, 2019, and $ 2,944 at September 30, 2018, related to amounts Woodward owed the JV. Upon the October 1, 2018 adoption of ASC 606, Woodward recorded $ 57,529 of revenue recognized in prior periods for the JV’s engineering and development projects as an increase to contract liabilities in “Other liabilities” and $ 57,529 of costs recognized in prior periods as costs to fulfill a contract in “Other assets.” Woodward recognized an additional $ 14,340 during the fiscal year ended September 30, 2019 of contract liabilities in “Other liabilities,” and $ 14,324 during the fiscal year ended September 30, 2019 of additional costs to fulfill a contract in “Other assets.” In the fiscal year ended September 30, 2019, Woodward recognized a $ 2,774 reduction in the cost to fulfill a contract in “Other assets” but a reduction of $ 2,790 in the contract liability in “Other liabilities” related to the termination of a JV engineering and development project previously recognized as a material right.

Financial Instruments and Fair Value Measurments
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, 2019 At September 30, 2018 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Financial assets: Cash $ 52,971 $ - $ - $ 52,971 $ 59,838 $ - $ - $ 59,838 Investments in reverse repurchase agreements 886 - - 886 4,582 - - 4,582 Investments in term deposits with foreign banks 45,216 - - 45,216 19,174 - - 19,174 Equity securities 20,504 - - 20,504 19,730 - - 19,730 Cross currency interest rate swaps - 24,758 - 24,758 - - - - Total financial assets $ 119,577 $ 24,758 $ - $ 144,335 $ 103,324 $ - $ - $ 103,324 Financial liabilities: Cross currency interest rate swaps $ - $ - $ - $ - $ - $ 23,000 $ - $ 23,000 Total financial liabilities $ - $ - $ - $ - $ - $ 23,000 $ - $ 23,000 Investments in reverse repurchase agreements: Woodward sometimes invests excess cash in reverse repurchase agreements. Under the terms of Woodward’s reverse repurchase agreements, Woodward purchases an interest in a pool of securities and is granted a security interest in those securities by the counterparty to the reverse repurchase agreement. At an agreed upon date, generally the next business day, the counterparty repurchases Woodward’s interest in the pool of securities at a price equal to what Woodward paid to the counterparty plus a rate of return determined daily per the terms of the reverse repurchase agreement. Woodward believes that the investments in these reverse repurchase agreements are with creditworthy financial institutions and that the funds invested are highly liquid. The investments in reverse repurchase agreements are reported at fair value, with realized gains from interest income recognized in earnings, and are included in “Cash and cash equivalents” in the Consolidated Balance Sheets. Since the investments are generally overnight, the carrying value is considered to be equal to the fair value as the amount is deemed to be a cash deposit with no risk of change in value as of the end of each fiscal quarter. 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. As of September 30, 2018, $ 3,635 of the term deposits with foreign banks were restricted in use as they were pledged collateral for short-term borrowings. The restriction lapsed during the first quarter of fiscal year 2019 when the related short-term borrowings were paid. 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. As of September 30, 2019, swaps in an asset position in the amount of $ 24,758 were included in “Other assets” in the Consolidated Balance Sheets. As of September 30, 2018, swaps in a liability position in the amount of $ 23,000 were included in “Other liabilities” in the Consolidated Balance Sheets. 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, 2019 At September 30, 2018 Fair Value Hierarchy Level Estimated Fair Value Carrying Cost Estimated Fair Value Carrying Cost Assets: Notes receivable from municipalities 2 $ 13,100 $ 12,346 $ 13,458 $ 13,462 Investments in short-term time deposits 2 13,468 13,509 8,883 8,874 Liabilities: Long-term debt 2 $ ( 928,618 ) $ ( 867,377 ) $ ( 1,094,987 ) $ ( 1,095,292 ) 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 1.7 % at September 30, 2019 and 3.1 % at September 30, 2018. 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 5.7 % at September 30, 2019 and 6.3 % at September 30, 2018. 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 2.5 % at September 30, 2019 and 3.5 % at September 30, 2018.

Derivative Instruments and Hedging Activities
Derivative Instruments and Hedging Activities	Note 8. Derivative instruments and hedging activities Derivative instruments not designated or qualifying as hedging instruments On April 18, 2018, Woodward entered into an at-the-money forward option at a cost of $ 5,543 (the “Forward Option”) whereby, on May 30, 2018, Woodward had the ability to exercise its option to purchase € 490,000 on June 1, 2018 using U.S. dollars at a fixed exchange rate of 1.2432 . The Forward Option was entered into to manage Woodward’s exposure to fluctuations in the Euro prior to the anticipated close of the L’Orange Agreement, which provided for payment in Euros. Woodward did not enter into the Forward Option for trading or speculative purposes. As the spot rate was below 1.2432 on May 30, 2018, Woodward elected not to exercise the option and a loss of $ 5,543 was recognized on the Forward Option in “Other (income) expense, net” in the Consolidated Statements of Earnings in the fiscal year ended September 30, 2018. The Forward Option expired on June 1, 2018. In May 2018, Woodward entered into cross currency interest rate swap agreements that synthetically convert $ 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 convert an aggregate principal amount of $ 400,000 of fixed-rate debt associated with the 2018 Note Purchase Agreement (as defined in Note 14, Credit facilities short-term borrowings and long-term debt ) to Euro denominated fixed-rate debt (the “Fixed-Rate Cross Currency Swaps”). The cross currency interest rate swaps, which effectively reduce the interest rate on the underlying fixed and floating-rate debt under the 2018 Notes (as defined in Note 14, Credit facilities short-term borrowings and long-term debt ) and Woodward’s then existing revolving credit agreement, respectively, is recorded as a reduction to “Interest expense” in Woodward’s Consolidated Statements of Earnings. Derivatives instruments in fair value hedging relationships Concurrent with the entry into the Floating-Rate Cross Currency Swap, 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 (“ASC 815”). The objective of the derivative instrument is to hedge against the foreign currency exchange risk attributable to the spot remeasurement of the Euro denominated intercompany loan. 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 other comprehensive (losses) earnings (“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 expenses” 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 denominated loan. 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 is no credit-risk-related contingent features associated with the 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, 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. 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 expenses” 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 denominated intercompany loans, including associated interest. Hedge effectiveness is assessed based on the fair value changes of the derivative instruments and 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. In June 2013, in connection with Woodward’s expected refinancing of current maturities on its then existing long-term debt, Woodward entered into a treasury lock agreement with a notional amount of $ 25,000 that qualified as a cash flow hedge under ASC 815. The objective of this derivative instrument was to hedge the risk of variability in cash flows attributable to changes in the designated benchmark interest rate over a seven year period related to the future principal and interest payments on a portion of anticipated future debt issuances. The treasury lock agreement was terminated in August 2013 and the resulting gain of $ 507 was recorded as a reduction to accumulated OCI, net of tax, and is being recognized as a decrease to interest expense over a seven year period. Woodward expects to reclassify $ 72 of net unrecognized gains on terminated derivative instruments from accumulated OCI to earnings during the next twelve month s. 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. Woodward issued € 40,000 aggregate principal amount of Woodward’s Series M Senior Notes due September 23, 2026 (the “Series M Notes”). Woodward designated the Series M Notes as a hedge of a foreign currency exposure of Woodward’s net investment in its Euro denominated functional currency subsidiaries. Related to the Series M Notes, included in foreign currency translation adjustments within total comprehensive (losses) earnings are net foreign exchange gains of $ 2,682 for the fiscal year ended September 30, 2019, compared to net foreign exchanges gains of $ 838 for the fiscal year ended September 30, 2018 and net foreign exchange losses of $ 2,395 for the fiscal year ended September 30, 2017. In July 2016, Woodward designated an intercompany loan of 160,000 RMB between two wholly owned subsidiaries as a hedge of a foreign currency exposure of the net investment of the borrower in the lender. In July 2017, the intercompany loan was repaid, resulting in a realized gain of $ 380 that was recognized within total comprehensive (losses) earnings, of which a gain of $ 453 was recognized in fiscal year 2017. Impact of derivative instruments designated as qualifying hedging instruments The following table discloses the impact of derivative instruments designated as qualifying hedging instruments on Woodward’s Consolidated Statements of Earnings: Year ended September 30, 2019 Derivatives in: Location Amount of (Income) Expense Recognized in Earnings on Derivative Amount of (Gain) Loss Recognized in Accumulated OCI on Derivative Amount of (Gain) Loss Reclassified from Accumulated OCI into Earnings Cross currency interest rate swap agreement designated as fair value hedges Selling, general and administrative expenses $ ( 9,394 ) $ ( 8,317 ) $ ( 8,356 ) Cross currency interest rate swap agreements designated as cash flow hedges Selling, general and administrative expenses ( 23,018 ) ( 39,442 ) ( 23,018 ) Treasury lock agreement designated as cash flow hedge Interest expense ( 72 ) - ( 72 ) $ ( 32,484 ) $ ( 47,759 ) $ ( 31,446 ) Year ended September 30, 2018 Derivatives in: Location Amount of (Income) Expense Recognized in Earnings on Derivative Amount of (Gain) Loss Recognized in Accumulated OCI on Derivative Amount of (Gain) Loss Reclassified from Accumulated OCI into Earnings Cross currency interest rate swap agreement designated as fair value hedges Selling, general and administrative expenses $ 472 $ 1,034 $ 472 Cross currency interest rate swap agreements designated as cash flow hedges Selling, general and administrative expenses 1,067 21,966 1,067 Treasury lock agreement designated as cash flow hedge Interest expense ( 72 ) - ( 72 ) $ 1,467 $ 23,000 $ 1,467 Year ended September 30, 2017 Derivatives in: Location Amount of (Income) Expense Recognized in Earnings on Derivative Amount of (Gain) Loss Recognized in Accumulated OCI on Derivative Amount of (Gain) Loss Reclassified from Accumulated OCI into Earnings Cross currency interest rate swap agreement designated as fair value hedges Selling, general and administrative expenses $ - $ - $ - Cross currency interest rate swap agreements designated as cash flow hedges Selling, general and administrative expenses - - - Treasury lock agreement designated as cash flow hedge Interest expense ( 72 ) - ( 72 ) $ ( 72 ) $ - $ ( 72 ) The remaining unrecognized gains and losses in Woodward’s Consolidated Balance Sheets associated with derivative instruments that were previously entered into by Woodward, which are classified in accumulated OCI were net gains of $ 5,004 as of September 30, 2019 and net losses of $ 21,315 as of September 30, 2018.

There are currently no operations in the Duarte, California facility, and the sale of the plant and related property is expected to close by March 31, 2020. The carrying value of the assets at the Duarte facility was $ 7,769 as of September 30, 2019, all of which the Company identified as assets held for sale as of that date. At September 30, 2018, the Company identified assets held for sale of $ 8,306 . The majority of the assets held for sale are included in “Land and land improvements” and “Buildings and buildings improvements” which relate to the land, building and building improvements, and other assets at the Duarte facility. The assets held for sale are included in unallocated corporate property, plant and equipment. Based on current market conditions, the Company expects to record a gain on the eventual sale of these assets. The Company assessed whether the decision to relocate from its Duarte facility could indicate a potential impairment of the assets at the Duarte facility and concluded that the assets were not impaired as of September 30, 2019. Included in “Construction in progress” are costs of $ 21,195 at September 30, 2019 and $ 32,248 at September 30, 2018 associated with new equipment purchases for the greater-Rockford, Illinois campus and costs of $ 239 at September 30, 2019 and $ 3,967 at September 30, 2018 associated with new equipment purchases and the renovation of the Drake Campus.

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, 2019 during the quarter ended September 30, 2019. At that date, Woodward determined it was appropriate to aggregate certain components of the same operating segment into a single reporting unit. The fair value of each of Woodward’s reporting units was determined using a discounted cash flow method. This method represents a level 3 input and incorporates various estimates and assumptions, the most significant being projected revenue growth rates, earnings margins, 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 forecasted cash flows. Management projects revenue growth rates, earnings margins and cash flows based on each reporting unit’s current operational results, expected performance and operational strategies over a ten-year period. These projections are adjusted to reflect current economic conditions and demand for certain products, and require considerable management judgment. Forecasted cash flows used in the July 31, 2019 impairment test were discounted using weighted-average cost of capital assumptions ranging from 9.35 % to 17.41 %. The terminal values of the forecasted cash flows were calculated using the Gordon Growth Model and assumed an annual compound growth rate after ten years of 3.39 %. 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. As discussed at Note 21, Commitments and contingencies , on April 9, 2019, German wind turbine manufacturer, Senvion GmbH (“Senvion”), a significant customer of Woodward’s renewables business, announced that it filed for self-administration insolvency proceedings. In conjunction with this, during the three-months ended June 30, 2019, Woodward determined that this action by Senvion represented a triggering event requiring an interim goodwill impairment test of its renewable power systems reporting unit. Based on the results of this interim impairment test, Woodward determined the renewable power systems reporting unit’s goodwill was not impaired as of June 30, 2019. The results of Woodward’s goodwill impairment tests performed as of July 31, 2019 did not indicate impairment of any of Woodward’s reporting units. As of the July 31, 2019 goodwill impairment test, the reporting unit with the closest ratio of estimated fair value to carrying value was our renewable power systems reporting unit, due primarily to the loss of Senvion as a customer. Woodward’s July 31, 2019 goodwill analysis indicated a premium of approximately 20 % compared to the renewable power system’s carrying value. Woodward is not aware of any facts, circumstances or triggering events that have arisen indicating that goodwill has been impaired or that the premium of approximately 20 % has changed significantly since Woodward’s July 31, 2019 analysis.

The impairment test consists of comparing the fair value of the Woodward L’Orange tradename 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 tradename 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 for this asset. During the fourth quarter, Woodward completed its annual impairment test of the Woodward L’Orange tradename intangible asset as of July 31, 2019 for the fiscal year ended September 30, 2019. The fair value of the Woodward L’Orange tradename 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 ten-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, 2019 impairment test was discounted using weighted-average cost of capital assumption of 10.44 %. The terminal value of the forecasted cash flow was calculated using the Gordon Growth Model and assumed an annual compound growth rate after ten years of 3.39 %. 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, 2019 indicated the estimated fair value of the Woodward L’Orange tradename intangible asset was in excess of its carrying value, and accordingly, no impairment existed. Finite lived intangible assets For the fiscal years ended September 30, 2019, 2018, and 2017, Woodward recorded amortization expense associated with intangibles of the following: Year Ended September 30, 2019 2018 2017 Amortization expense $ 56,022 $ 44,742 $ 25,777 Future amortization expense associated with intangibles is expected to be: Year Ending September 30: 2020 $ 39,713 2021 40,649 2022 38,451 2023 37,393 2024 33,616 Thereafter 358,703 $ 548,525

On June 19, 2019, Woodward amended the Revolving Credit Agreement (the “Amended and Restated Revolving Credit Agreement”) to, among other things, (i) increase the option to increase available borrowings from $ 1,200,000 to $ 1,500,000 , (ii) continue the commitments of the lenders thereunder to make revolving loans in an aggregate principal amount of up to $ 1,000,000 , or $ 1,500,000 subject to lenders’ participation, (iii) extend the termination date of the revolving loan commitments of all the lenders from April 28, 2020 to June 19, 2024 , and (iv) subject to conforming changes to the Company’s existing note purchase agreements, modify the definition of “EBITDA” to add-back acquisition related transaction costs associated with permitted acquisitions and increase the minimum consolidated net worth covenant from $ 800,000 to $ 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. Borrowings under the Amended and Restated 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 %. Under the Amended and Restated Revolving Credit Agreement, there were $ 262,297 in principal amount of borrowings outstanding as of September 30, 2019, at an effective interest rate of 3.01 %. Under the prior Revolving Credit Agreement, there were $ 266,541 in principal amount of borrowings outstanding as of September 30, 2018, at an effective interest rate of 3.48 % . The Amended and Restated 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 as well as the preceding Revolving Credit Agreement, 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 Amended and Restated 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 Amended and Restated 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. As of September 30, 2019, $ 220,000 of the borrowings under the Amended and Restated Revolving Credit Agreement were classified as short-term borrowings, and as of September 30, 2018, $ 150,000 of the borrowings under the Revolving Credit Agreement were classified as short-term borrowings based on Woodward’s intent and ability to pay this amount in the next twelve months. 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. Pursuant to the terms of the related facility agreements, Woodward’s foreign performance guarantee facilities are limited in use to providing performance guarantees to third parties. There were no borrowings outstanding on Woodward’s foreign lines of credit and foreign overdraft facilities as of both September 30, 2019 and September 30, 2018. Woodward had no other short-term borrowings as of September 30, 2019 and other short-term borrowings of $ 3,635 as of September 30, 2018, which were repaid during the first quarter of fiscal year 2019.

In April 2009, Woodward entered into a note purchase agreement relating to the Series F Notes, which were due on April 3, 2019. On April 3, 2019, Woodward paid the entire principal balance of $ 43,000 on the Series F Notes using proceeds from borrowings under its revolving credit facility. On October 1, 2013, Woodward entered into a note purchase agreement relating to the sale by Woodward of an aggregate principal amount of $ 250,000 of its senior unsecured notes in a series of private placement transactions. 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 together with the Series D Notes, the Series F Notes and the First Closing Notes, collectively the “USD Notes”) on November 15, 2013. 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 (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. Interest on the Series J Notes is payable quarterly on January 1, April 1, July 1 and October 1 of each year until all principal is paid. As of September 30, 2019, the Series J Notes bore interest at an effective rate of 3.37 %. Interest on the 2018 Notes is payable semi-annually on May 30 and November 30 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. For the Series G, H, I, J, K, L, M, N, and O notes, Woodward’s consolidated net worth must at all times equal or exceed $ 1,156,000 plus 50 % of Woodward’s positive net income for each completed fiscal year beginning with the fiscal year ending September 30, 2016. For the 2018 Notes, Woodward’s consolidated net worth must at all times equal or exceed $ 1,156,000 plus (i) 50 % of Woodward’s positive net income for each completed fiscal year beginning with the fiscal year ending September 30, 2018 and (ii) 50 % of the net cash proceeds received by Woodward on or after May 31, 2018 from the issuance of capital stock, other than issuances pursuant to employee stock option or ownership plans. The Company, at its option, is permitted at any time to prepay all or any part of the then-outstanding principal amount of any series of the Notes at 100 % of the principal amount of the series of the Notes to be prepaid (but, in the case of partial prepayment, not less than $ 1,000 for each the USD Notes and the 2018 Notes and not less than € 1,000 for the 2016 Notes), together with interest accrued on such amount to be prepaid to the date of prepayment, plus any applicable prepayment compensation amount. The prepayment compensation amount, as to the USD Notes and 2018 Notes, other than the Series J Notes, is computed by discounting the remaining scheduled payments of interest and principal of the USD Notes and/or 2018 Notes being prepaid at a discount rate equal to the sum of 50 basis points and the yield to maturity of U.S. Treasury securities having a maturity equal to the remaining average life of the USD Notes and/or 2018 Notes being prepaid. The prepayment compensation amount, as to the Series J Notes, generally is computed as a percentage of the principal amount of the Series J Notes equal to 0 % after November 15, 2015. The prepayment compensation amount as to the 2016 Notes that is not subject to a swap agreement is computed by discounting the remaining scheduled payments of interest and principal of such notes being prepaid at a discount rate equal to the sum of 50 basis points and the yield to maturity of the German Bund having a maturity equal to the remaining average life of the 2016 Notes being prepaid. The prepayment compensation amount as to a 2016 Notes that is subject to a swap agreement entered into by the holder of such note under which the holder will receive payment in U.S. dollars in exchange for scheduled Euro payments of principal and interest on the Euro denominated 2016 Notes, adjusted for theoretical holder returns foregone on hypothetical reinvestments in U.S. Treasury securities (the “Swapped Notes”) is equal to the excess of an amount equal to the remaining scheduled payments to be paid in respect of such called principal under such swap agreement discounted at a rate equal to 50 basis points and the yield to maturity of U.S. Treasury securities having a maturity equal to the remaining average life of the Swapped Notes being prepaid over the amount of payments in U.S. dollars that would be paid to the holder of the Swapped Note in respect of the called principal under the swap agreement, which amount will be increased or reduced, as applicable, in an amount equal to any net gain or loss realized by the holder of such Swapped Note on swap transactions under such swap agreement as a result of such prepayment. Required future principal payments of the Notes as of September 30, 2019 are as follows: Year Ending September 30: 2020 $ - 2021 100,000 2022 - 2023 - 2024 75,000 Thereafter 650,080 $ 825,080 Certain financial and other covenants under Woodward’s debt agreements contain customary restrictions on the operation of its business. Management believes that Woodward was in compliance with the covenants under the long-term debt agreements at September 30, 2019. Debt Issuance Costs Amounts recognized as interest expense from the amortization of debt issuance costs were $ 1,094 in fiscal year 2019, $ 1,256 in fiscal year 2018, and $ 1,130 in fiscal year 2017. Unamortized debt issuance costs associated with the Notes of $ 2,478 as of September 30, 2019 and $ 2,895 as of September 30, 2018 were recorded as a reduction in “Long-term debt, less current portion” in the Consolidated Balance Sheets. In connection with the Amended and Restated Revolving Credit Agreement, Woodward incurred $ 2,238 in debt issuance costs, which are deferred and are being amortized using the straight-line method over the life of the agreement. As of June 19, 2019, the date the Amended and Restated Revolving Credit Agreement was entered into, Woodward had $ 802 of deferred debt issuance costs remaining that were incurred in connection with the then existing revolving credit agreement, which have been combined with the deferred debt issuance costs associated with the Amended and Restated Revolving Credit Agreement and are being amortized using the straight-line method over the life of the Amended and Restated Revolving Credit Agreement. Unamortized debt issuance costs of $ 2,840 associated with these revolving credit agreements as of September 30, 2019 and $ 1,385 as of September 30, 2018 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.

During the third quarter of fiscal year 2017, Woodward entered into another sublease agreement with a third party related to a portion of the vacated Skokie facility. Woodward recorded a reduction in the loss reserve associated with the vacated Skokie facility of $ 2,322 related to the anticipated sublease income it will receive. The summary for the activity in the loss reserve during the fiscal years ended September 30, 2019, 2018, and 2017 is as follows: p Twelve-Months Ended September 30, 2019 2018 2017 Loss reserve on contractual lease commitments, beginning of period $ 3,931 $ 5,270 $ 9,242 Payments ( 932 ) ( 1,339 ) ( 1,650 ) Non-cash adjustments - - ( 2,322 ) Loss reserve on contractual lease commitments, end of period $ 2,999 $ 3,931 $ 5,270 Other liabilities included $ 1,754 and $ 2,686 of accrued loss reserve on contractual lease commitments as of September 30, 2019 and September 30, 2018, respectively, which are not expected to be settled or paid within twelve months of the respective balance sheet date, net of expected sublease income. Restructuring charges In fiscal year 2018, the Company recorded restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The Duarte facility, which manufactures thrust reverser actuation systems, is part of the Company’s Aerospace segment. The remaining restructuring charges recognized during the fiscal year ended September 30, 2018 consist of workforce management costs related to aligning the Company’s industrial turbomachinery business, which is part of the Company’s Industrial segment, with the then current market conditions. All of the restructuring charges recorded during the fiscal year ended September 30, 2018 were recorded as nonsegment expenses and are expected to be paid within one year of the balance sheet date. The summary of activity in accrued restructuring charges during the fiscal years ended September 30, 2019 and September 30, 2018 is as follows: Period Activity Balances as of October 1, 2018 Charges (gains) Cash receipts (payments) Non-cash activity Balances as of September 30, 2019 Workforce management costs associated with: Duarte plant relocation $ 12,504 $ - $ ( 8,685 ) $ ( 3,379 ) $ 440 Industrial turbomachinery business realignment 4,018 - ( 3,760 ) ( 191 ) 67 Total $ 16,522 $ - $ ( 12,445 ) $ ( 3,570 ) $ 507 Period Activity Balances as of October 1, 2017 Charges (gains) Cash receipts (payments) Non-cash activity Balances as of September 30, 2018 Workforce management costs associated with: Duarte plant relocation $ - $ 12,504 $ - $ - $ 12,504 Industrial turbomachinery business realignment - 4,509 ( 491 ) - 4,018 Total $ - $ 17,013 $ ( 491 ) $ - $ 16,522 T

A portion of these NOL carryforwards started to expire in 2019 and are currently offset by a valuation allowance. Woodward has placed valuation allowances against all other 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 the expiration of net operating losses at a wholly owned subsidiary. At September 30, 2019, Woodward has not provided for taxes on undistributed foreign earnings of $ 293,538 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. On December 22, 2017 the U.S. enacted the Tax Act. The Tax Act included significant changes to prior tax law, including a permanent reduction to the U.S federal corporate income tax rate of 35 % to 21 %, a one-time repatriation tax on deferred foreign income (“Transition Tax”), deemed inclusions of foreign low tax earnings, limitations on certain deductions, adjusted foreign tax credits, and business-related exclusions. Enactment of the Tax Act during December 2017 resulted in a net change to Woodward’s income tax expense in the amount of $ 14,778 , which was recorded in the three-months ended December 31, 2017. After adjustments to amounts made throughout fiscal year 2018, the net impact of the enactment of the Tax Act was $ 10,860 . Woodward finalized its assessment of the income tax effects of the Tax Act in the first quarter of fiscal year 2019. On June 14, 2019, the Internal Revenue Service (“IRS”) issued final regulations that modified the Transition Tax computation required by the Tax Act. As a result, in the three-months ended June 30, 2019, Woodward recognized additional income tax expense related to the Transition Tax of $ 10,588 . The permanent reduction to the U.S. federal corporate income tax rate from 35 % to 21 % was effective January 1, 2018 (the “Effective Date”). When a U.S. federal tax rate change occurs during a taxpayer’s fiscal year, taxpayers are required to compute a weighted daily average rate for the fiscal year of enactment. As a result of the Tax Act, Woodward calculated a U.S. federal statutory corporate income tax rate of 24.5 % for the fiscal year ending September 30, 2018 and applied this rate in computing the income tax provision for the fiscal year ended September 30, 2018. The U.S. federal statutory corporate income tax rate of 24.5 % is the weighted daily average rate between the pre-enactment U.S. federal statutory tax rate of 35 % applicable to Woodward’s 2018 fiscal year prior to the Effective Date and the post-enactment U.S. federal statutory tax rate of 21 % applicable to the 2018 fiscal year after the Effective Date. The U.S. federal statutory rate is 21 % for the fiscal year ended September 30, 2019. The following is a reconciliation of the U.S. Federal statutory tax 21.0 % in the fiscal year ended September 30, 2019, 24.5 % in fiscal year ended September 30, 2018 and 35 % in the fiscal year ended September 30, 2017 to Woodward’s effective income tax rate: Year Ending September 30, 2019 2018 2017 Percent of pretax earnings Statutory tax rate 21.0 % 24.5 % 35.0 % State income taxes, net of federal tax benefit ( 0.1 ) ( 0.5 ) ( 0.3 ) Taxes on international activities 0.2 ( 1.8 ) ( 7.6 ) Research credit ( 3.3 ) ( 4.8 ) ( 3.2 ) Net excess income tax benefit from stock-based compensation ( 3.5 ) ( 1.4 ) ( 1.4 ) Domestic production activities deduction - ( 1.6 ) ( 1.5 ) Adjustments of prior period tax items 0.9 ( 5.0 ) ( 0.9 ) Effect of U.S. federal corporate rate reduction on net beginning U.S. deferred tax liability - ( 5.0 ) - Transition Tax 3.3 6.2 - Increased deferred tax liability associated with anticipated repatriation taxes - 3.7 - Effect of U.S. federal corporate rate reduction on net current year U.S. deferred tax activity - 2.0 - Other items, net 0.5 1.6 0.6 Effective tax rate 19.0 % 17.9 % 20.7 % 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 majority of these adjustments are related to the conclusion of audits, effective settlement, and lapse of applicable statutes of limitations in various tax jurisdictions. The increase in the effective tax rate for fiscal year 2019 compared to fiscal year 2018 is primarily attributable to favorable resolutions of tax matters in the prior fiscal year that did not repeat in the current fiscal year, an increase in the U.S. federal corporate income tax on current year foreign earnings, the loss of the domestic production activities deduction in the year and a decrease in the current year of the U.S. research and experimentation credit as a percent of pretax earnings. Partially offsetting these increases were the decrease in the U.S federal corporate income tax rate from 24.5 % for fiscal year 2018 to 21.0 % in the current fiscal year and the related impact on fiscal year 2018 deferred tax activity that did not repeat in the current fiscal year. Additionally, the fiscal year 2018 net tax expense increase related to the Tax Act was larger than the current fiscal year increase. Finally, the current fiscal year had a larger favorable increase in the net excess income tax benefits from stock-based compensation compared to fiscal year 2018. A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits follows: Year Ending September 30, 2019 2018 2017 Beginning balance $ 8,364 $ 20,132 $ 23,526 Additions to current year tax positions 1,930 2,675 2,560 Reductions to prior year tax positions - ( 14,458 ) ( 5,753 ) Additions to prior year tax positions 11 15 3,501 Lapse of applicable statute of limitations - - ( 3,702 ) Ending balance $ 10,305 $ 8,364 $ 20,132 Included in the balance of unrecognized tax benefits were $ 4,411 as of September 30, 2019 and $ 3,288 as of September 30, 2018 of tax benefits that, if recognized, would affect the effective tax rate. At this time, Woodward does not estimate it is reasonably possible that the liability for unrecognized tax benefits will decrease in the next twelve months. 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 had accrued gross interest and penalties of $ 437 as of September 30, 2019 and $ 279 as of September 30, 2018. 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 2017 and thereafter. Woodward is currently under examination by the Internal Revenue Service for fiscal year 2017 , 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 2015 and thereafter. Woodward closed various audits in foreign jurisdictions in the second and third quarters of fiscal year 2019. Consequently, fiscal years remaining open to examination in significant foreign jurisdictions include 2016 and thereafter.

Retirement Benefits [Abstract]
Retirement Benefits	Note 19. 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. Most of Woodward’s U.S. employees with at least two year s of service receive an annual contribution of Woodward stock, equal to 5 % of their eligible prior year wages, to their personal Woodward Retirement Savings Plan accounts. In the second quarters of fiscal years 2019, 2018, and 2017, Woodward fulfilled its annual Woodward stock contribution obligation using shares held in treasury stock by issuing a total of 158 shares of common stock for a value of $ 14,846 in fiscal year 2019, 202 total shares of common stock for a value of $ 14,741 in fiscal year 2018, and 199 shares of common stock for a value of $ 14,014 in fiscal year 2017. The Woodward Retirement Savings Plan (the “WRS Plan”) held 3,623 shares of Woodward stock as of September 30, 2019 and 3,955 shares as of September 30, 2018. 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 $ 11,701 as of September 30, 2019 and $ 11,475 as of September 30, 2018. The amount of expense associated with defined contribution plans was as follows: Year Ended September 30, 2019 2018 2017 Company costs $ 35,510 $ 34,084 $ 32,008 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. On October 26, 2018, the High Court of Justice in the United Kingdom (the “High Court”) issued a ruling (the “Court Ruling”) requiring defined benefit plan sponsors in the United Kingdom to equalize benefits payable to men and women under its United Kingdom defined benefit pension plans by amending those plans to increase the pension benefits payable to participants that accrued such benefits during the period from 1990 to 1997. In the Court Ruling, the High Court also provided details on acceptable alternative methods of amending plans to equalize the pension benefits. Although final guidance around the appropriate equalization methodology to be used has not yet been issued, Woodward has concluded that Court Ruling is applicable to its defined benefit pension plan in the United Kingdom and has made the necessary plan amendments. Woodward’s current estimate of the impact of the Court Ruling in the amount of $ 601 has been reflected in the United Kingdom defined benefit pension plan’s obligation and assets as of September 30, 2019 and will be amortized as a net prior service cost beginning in fiscal year 2020. Woodward does not expect any changes to the estimate resulting from final guidance around the appropriate equalization methodology to be used will be material to the United Kingdom defined benefit pension plan’s obligation and assets. In connection with the acquisition of L’Orange on June 1, 2018, Woodward assumed the unfunded defined benefit pension obligations of the L’Orange defined benefit pension plans in Germany (the “L’Orange Pension Plans”). Woodward’s assumption of the liability associated with the L’Orange Pension Plans was part of the total consideration paid by Woodward to acquire L’Orange and thus reduced Woodward’s cash payment for the transaction. Woodward has completed its valuation of the defined benefit pension obligations associated with the L’Orange Pension Plans and determined the value of the associated unfunded obligation was $ 39,257 , of which $ 1,143 was considered current as of the June 1, 2018 acquisition date. The L’Orange Pension Plans had expenses of $ 2,004 and $ 673 and Woodward made $ 782 and $ 219 of contributions to the L’Orange Pension Plans to pay participant benefits during the years ended September 30, 2019 and September 30, 2018, respectively. The L’Orange Pension Plans are unfunded. 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: 2019 2018 2017 United States: Weighted-average assumptions to determine benefit obligation at September 30: Discount rate 3.25 % 4.35 % 3.80 % Weighted-average assumptions to determine periodic benefit costs for years ended September 30: Discount rate 4.35 3.80 3.65 Long-term rate of return on plan assets 7.39 7.39 7.38 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. 2019 2018 2017 United Kingdom: Weighted-average assumptions to determine benefit obligation at September 30: Discount rate 1.74 % 2.68 % 2.56 % Rate of compensation increase 3.50 3.60 3.60 Weighted-average assumptions to determine periodic benefit costs for years ended September 30: Discount rate - service cost 2.70 2.58 2.33 Discount rate - interest cost 2.51 2.36 2.24 Rate of compensation increase 3.60 3.60 3.40 Long-term rate of return on plan assets 4.75 4.75 4.75 2019 2018 2017 Japan: Weighted-average assumptions to determine benefit obligation at September 30: Discount rate 0.53 % 0.62 % 0.58 % Rate of compensation increase 2.00 2.00 2.00 Weighted-average assumptions to determine periodic benefit costs for years ended September 30: Discount rate - service cost 0.80 0.72 0.59 Discount rate - interest cost 0.42 0.38 0.45 Rate of compensation increase 2.00 2.00 2.02 Long-term rate of return on plan assets 2.50 2.50 2.50 2019 2018 2017 Germany: Weighted-average assumptions to determine benefit obligation at September 30: Discount rate 0.81 % 1.87 % n/a Rate of compensation increase 2.50 2.50 n/a Weighted-average assumptions to determine periodic benefit costs for years ended September 30: Discount rate - service cost 2.06 2.05 n/a Discount rate - interest cost 1.53 1.49 n/a Rate of compensation increase 2.50 2.50 n/a 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, 2019 and 2018, 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, 2018 and 2017 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, 2019 and September 30, 2018 were based on the Society of Actuaries (“SOA”) RP-2014 Mortality Tables Report projected back to 2006 using the SOA’s Mortality Improvement Scale MP-2014 (“MP-2014”) and projected forward using a custom projection scale based on MP-2014 with a 10 -year convergence period and a long-term rate of 0.75 %. As of September 30, 2019 and September 30, 2018, mortality assumptions in Japan were based on the Standard rates 2014 and mortality assumptions for the United Kingdom pension scheme were based on the Self-administered pension scheme (“SAPS”) S2 “all” tables with a projected 1.5 % annual improvement rate. As of September 30, 2019 and mortality assumptions in Germany were based on the Heubeck 2018 G mortality tables whereas at September 30, 2018 mortality assumptions in Germany were based on Heubeck 2005 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 2019 2018 2017 2019 2018 2017 2019 2018 2017 Service cost $ 1,451 $ 1,643 $ 1,675 $ 2,036 $ 1,124 $ 1,133 $ 3,487 $ 2,767 $ 2,808 Interest cost 6,384 6,004 5,757 1,906 1,526 1,208 8,290 7,530 6,965 Expected return on plan assets ( 11,986 ) ( 11,614 ) ( 10,529 ) ( 2,638 ) ( 2,780 ) ( 2,605 ) ( 14,624 ) ( 14,394 ) ( 13,134 ) Amortization of: Net losses 617 598 1,854 283 291 514 900 889 2,368 Net prior service cost 709 709 383 - - - 709 709 383 Net periodic (benefit) cost $ ( 2,825 ) $ ( 2,660 ) $ ( 860 ) $ 1,587 $ 161 $ 250 $ ( 1,238 ) $ ( 2,499 ) $ ( 610 ) 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 2019 2018 2019 2018 2019 2018 Changes in projected benefit obligation: Projected benefit obligation at beginning of year $ 150,032 $ 161,130 $ 103,485 $ 66,369 $ 253,517 $ 227,499 Plan amendment - - 601 - 601 - Obligation assumed in L'Orange acquisition - - - 39,257 - 39,257 Service cost 1,451 1,643 2,036 1,124 3,487 2,767 Interest cost 6,384 6,004 1,906 1,526 8,290 7,530 Net actuarial losses (gains) 23,841 ( 13,128 ) 22,174 ( 383 ) 46,015 ( 13,511 ) Contribution by participants - 34 9 9 9 43 Benefits paid ( 6,113 ) ( 5,651 ) ( 3,181 ) ( 2,888 ) ( 9,294 ) ( 8,539 ) Foreign currency exchange rate changes - - ( 5,495 ) ( 1,529 ) ( 5,495 ) ( 1,529 ) Projected benefit obligation at end of year $ 175,595 $ 150,032 $ 121,535 $ 103,485 $ 297,130 $ 253,517 Changes in fair value of plan assets: Fair value of plan assets at beginning of year $ 165,342 $ 160,332 $ 62,380 $ 64,380 $ 227,722 $ 224,712 Actual return on plan assets 11,327 10,627 5,121 1,407 16,448 12,034 Contributions by the Company - - 1,697 994 1,697 994 Contributions by plan participants - 34 9 9 9 43 Benefits paid ( 6,113 ) ( 5,651 ) ( 3,181 ) ( 2,888 ) ( 9,294 ) ( 8,539 ) Foreign currency exchange rate changes - - ( 2,449 ) ( 1,522 ) ( 2,449 ) ( 1,522 ) Fair value of plan assets at end of year $ 170,556 $ 165,342 $ 63,577 $ 62,380 $ 234,133 $ 227,722 Net (under)/over funded status at end of year $ ( 5,039 ) $ 15,310 $ ( 57,958 ) $ ( 41,105 ) $ ( 62,997 ) $ ( 25,795 ) At September 30, 2019, the Company’s defined benefit pension plans in the United Kingdom, Japan and Germany represented $ 58,494 , $ 11,110 and $ 51,931 of the total projected benefit obligation, respectively. At September 30, 2019, the United Kingdom and Japan pension plan assets represented $ 52,105 and $ 11,472 of the total fair value of all plan assets, respectively. The German pension plans are unfunded and have no plan assets. The accumulated benefit obligations of the Company’s defined benefit pension plans at September 30, 2019 was $ 175,595 in the United States, $ 56,389 in the United Kingdom, $ 10,081 in Japan, and $ 51,908 in Germany, and at September 30, 2018 was $ 150,032 in the United States, $ 50,594 in the United Kingdom, $ 9,975 in Japan and $ 40,358 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, 2019 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 2020 $ 7,170 $ 3,631 $ 10,801 2021 7,823 3,363 11,186 2022 8,383 3,239 11,622 2023 8,924 3,805 12,729 2024 9,385 3,695 13,080 2025 – 2029 51,139 19,494 70,633 Woodward expects its pension plan contributions in fiscal year 2020 will be $ 657 in the United Kingdom, $ 234 in Japan and $ 1,061 in Germany. Woodward expects to have no pension plan contributions in fiscal year 2020 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. A pension oversight committee is assigned by the Company to each pension plan. Among other responsibilities, each committee is responsible for all asset class allocation decisions. Asset class allocations, which are reviewed by the respective pension committee on at least an annual basis, are designed to meet or exceed certain market benchmarks and align with each plan’s investment objectives. In evaluating the asset allocation choices, consideration is given to the proper long-term level of risk for each plan, particularly with respect to the long-term nature of each plan’s liabilities, the impact of asset allocation on investment results and the corresponding impact on the volatility and magnitude of plan contributions and expense and the impact certain actuarial techniques may have on the plans’ recognition of investment experience. From time to time, the plans may move outside the prescribed asset class allocation in order to meet significant liabilities with respect to one or more individuals approaching retirement. 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, 2019 and 2018 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, 2019 2018 Percentage of Plan Assets Target Allocation Ranges Percentage of Plan Assets Target Allocation Ranges United States: Asset Class Equity Securities 60.6 % 41.4 % - 81.4 % 65.1 % 41.5 % - 81.5 % Debt Securities 37.9 % 28.6 % - 48.6 % 33.1 % 28.5 % - 48.5 % Other 1.5 % 0.0 % 1.8 % 0.0 % 100.0 % 100.0 % United Kingdom: Asset Class Equity Securities 41.6 % 30.0 % - 60.0 % 44.8 % 30.0 % - 60.0 % Debt Securities 57.8 % 45.0 % - 70.0 % 54.8 % 45.0 % - 70.0 % Other 0.6 % 0.0 % 0.4 % 0.0 % 100.0 % 100.0 % Japan: Asset Class Equity Securities 41.4 % 36.0 % - 44.0 % 41.0 % 36.0 % - 44.0 % Debt Securities 57.7 % 55.0 % - 63.0 % 58.1 % 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 2019 or 2018. 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 and the United Kingdom. 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 695 retired employees and their covered dependents and beneficiaries and may provide future benefits to 8 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: 2019 2018 2017 Weighted-average discount rate used to determine benefit obligation at September 30 3.05 % 4.30 % 3.78 % Weighted-average discount rate used to determine net periodic benefit cost for years ended September 30 4.30 3.80 3.63 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. In the United States, 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. In the United Kingdom, 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. 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, 2019 and September 30, 2018 mortality assumptions were based on the SOA’s RP-2014 Mortality Tables Report projected back to 2006 using the SOA’s MP-2014 and projected forward using a custom projection scale based on MP-2014 with a 10 -year convergence period and a long-term rate of 0.75 %. As of September 30, 2019 and September 30, 2018, mortality assumptions for the United Kingdom postretirement medical plan were based on the SAPS S2 “all” tables with a projected 1.5 % annual improvement rate. Assumed healthcare cost trend rates at September 30, were as follows: 2019 2018 Health care cost trend rate assumed for next year 6.25 % 6.50 % 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 2025 2025 Healthcare costs have generally trended upward in recent years, sometimes by amounts greater than 5%. Assumed health care cost trend rates have a significant effect on the amounts reported for postretirement medical plans. A one-percentage-point change in assumed health care cost trend rates would have the following effects: Change In Health Care Cost Trend Rate 1% increase 1% decrease Effect on projected fiscal year 2020 service and interest cost $ 74 $ ( 65 ) Effect on accumulated postretirement benefit obligation at September 30, 2019 2,417 ( 2,128 ) Net periodic benefit costs consist of the following components reflected as expense in Woodward’s Consolidated Statements of Earnings: Year Ended September 30, 2019 2018 2017 Service cost $ 5 $ 7 $ 14 Interest cost 1,154 1,165 1,244 Amortization of: Net losses 55 94 201 Net prior service benefit ( 5 ) ( 158 ) ( 158 ) Curtailment gain - ( 330 ) - Net periodic cost $ 1,209 $ 778 $ 1,301 The following table provides a reconciliation of the changes in the accumulated postretirement benefit obligation and fair value of assets for the postretirement benefits for the fiscal years ended September 30: Year Ended September 30, 2019 2018 Changes in accumulated postretirement benefit obligation: Accumulated postretirement benefit obligation at beginning of year $ 27,985 $ 32,252 Service cost 5 7 Interest cost 1,154 1,165 Premiums paid by plan participants 1,192 1,311 Net actuarial gains ( 373 ) ( 2,716 ) Benefits paid ( 3,292 ) ( 3,707 ) Curtailment - ( 330 ) Foreign currency exchange rate changes - 3 Accumulated postretirement benefit obligation at end of year $ 26,671 $ 27,985 Changes in fair value of plan assets: Fair value of plan assets at beginning of year $ - $ - Contributions by the company 2,100 2,396 Premiums paid by plan participants 1,192 1,311 Benefits paid ( 3,292 ) ( 3,707 ) Fair value of plan assets at end of year $ - $ - Funded status at end of year $ ( 26,671 ) $ ( 27,985 ) 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, 2019 2018 Amounts recognized in statement of financial position consist of: Accrued liabilities $ ( 2,048 ) $ ( 2,249 ) Other non-current liabilities ( 24,623 ) ( 25,736 ) Funded status at end of year $ ( 26,671 ) $ ( 27,985 ) Amounts recognized in accumulated other comprehensive income consist of: Unrecognized net prior service (benefit) cost $ 4 $ ( 1 ) Unrecognized net (gains) losses ( 3 ) 425 Total amounts recognized 1 424 Deferred taxes ( 414 ) ( 518 ) Amounts recognized in accumulated other comprehensive income $ ( 413 ) $ ( 94 ) Woodward pays plan benefits from its general funds; therefore, there are no segregated plan assets as of September 30, 2019 or September 30, 2018. The accumulated benefit obligations of the Company’s postretirement plans were $ 26,671 at September 30, 2019 and $ 27,985 at September 30, 2018.

Stockholders' Equity And Stock Based Compensation [Abstract]
Stockholders' Equity	Note 20. Stockholders’ equity Common Stock Holders of Woodward’s common stock are entitled to receive dividends when and as declared by Woodward’s board of directors and have the right to one vote per share on all matters requiring stockholder approval. Dividends declared and paid during 2019, 2018 and 2017 fiscal years were: Year Ended September 30, 2019 2018 2017 Dividends declared and paid $ 39,066 $ 34,003 $ 29,745 Dividend per share amount 0.6300 0.5525 0.4850 Stock repurchase program In the first quarter of fiscal year 2017, Woodward’s board of directors terminated the Company’s prior stock repurchase program and replaced it with a new 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 ended in November 2019 (the “2017 Authorization”). In fiscal year 2019, Woodward purchased 1,102 shares of its common stock for $ 110,311 under the 2017 Authorization pursuant to a 10b5-1 plan. Woodward repurchased no common stock under the 2017 Authorization in fiscal year 2018. In fiscal year 2017, Woodward purchased 1,027 shares of its common stock for $ 71,197 , of which 491 shares were purchased pursuant to a 10b5-1 plan and 536 shares were purchased pursuant to a 10b-18 plan. Effective upon the expiration of the 2017 Authorization, Woodward’s board of directors approved a new 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. 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, Woodward’s board of directors 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 30, 2019, Woodward’s stockholders approved an additional 1,400 shares of Woodward’s common stock to be made available for future grants. Under the 2017 Plan, there were approximately 1,783 shares of Woodward’s common stock available for future grants as of September 30, 2019. 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 term, and generally have a four year vesting schedule at a rate of 25 % per 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, 2019 2018 2017 Weighted-average exercise price per share $ 79.84 78.91 62.74 Weighted-average grant date market value of Woodward stock $ 79.84 78.91 69.45 Expected term (years) 6.5 - 8.7 6.4 - 8.7 6.0 - 8.7 Estimated volatility 25.7 % - 31.0 % 29.1 % - 32.7 % 30.6 % - 33.7 % Estimated dividend yield 0.6 % - 0.8 % 0.6 % 0.8 % 0.7 % Risk-free interest rate 1.5 % - 3.1 % 2.1 % - 2.8 % 2.0 % - 2.5 % The weighted average grant date fair value of options granted follows: Year Ended September 30, 2019 2018 2017 Weighted-average grant date fair value of options $ 24.12 $ 25.66 $ 24.98 The following is a summary of the activity for stock option awards during the fiscal year ended September 30, 2019: Number Weighted-Average Exercise Price Per Share Balance at September 30, 2018 5,611 $ 45.42 Options granted 924 79.84 Options exercised ( 1,102 ) 32.71 Options forfeited ( 44 ) 68.51 Options expired ( 2 ) 72.58 Balance at September 30, 2019 5,387 53.73 Exercise prices of stock options outstanding as of September 30, 2019 range from $ 25.57 to $ 116.10 .

Each restricted stock unit entitles the holder to one share of the Company’s common stock upon vesting. The restricted stock units were granted with a two year vesting schedule and vest on the one and two year anniversaries of the grant date at a rate of 50 % per year. The restricted stock units do not participate in dividends during the vesting period. The fair value of restricted stock units granted were estimated using the closing price of Woodward common stock on the grant date. A summary of the activity for restricted stock units in the fiscal year ended September 30, 2019: Number Weighted-Average Grant Date Fair Value per Unit Balance at September 30, 2018 10 $ 82.71 Units granted 4 102.94 Units vested ( 5 ) 82.71 Units forfeited - n/a Balance at September 30, 2019 9 91.55 Stock-based compensation expense Woodward recognizes stock-based compensation expense on a straight-line basis over the requisite service period. Pursuant to 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, 2019 2018 2017 Employee stock-based compensation expense $ 18,146 $ 18,229 $ 17,282 At September 30, 2019, there was approximately $ 12,713 of total unrecognized compensation expense related to non-vested stock-based compensation arrangements, including both stock options and restricted stock awards. The pre-vesting forfeiture rates for purposes of determining stock-based compensation expense recognized were estimated to be 0 % for members of Woodward’s board of directors and 9 % for all others. The remaining unrecognized compensation cost is expected to be recognized over a weighted-average period of approximately 2.2 years.

Commitments and Contingencies Disclosure
Commitments and Contingencies	Note 21. Commitments and contingencies Woodward has entered into operating leases for certain facilities, equipment, and software with terms in excess of one year under agreements that expire at various dates. Some leases require the payment of property taxes, insurance, and maintenance costs in addition to rental payments. Woodward has also entered into capital leases for equipment with terms in excess of one year under agreements that expire at various dates. Future minimum payments required under these leases are as follows: Year Ending September 30, Operating Leases Capital Leases 2020 $ 6,667 $ 213 2021 5,119 98 2022 3,823 33 2023 2,899 3 2024 2,378 - Thereafter 6,033 - Total $ 26,919 $ 347 Rent expense for all operating leases follows: Ut now Year Ended September 30, 2019 2018 2017 Rent expense $ 7,578 $ 8,348 $ 8,302 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, 2020 $ 419,944 2021 13,335 2022 1,155 2023 - 2024 - Thereafter - Total $ 434,434 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 year s following the change of control. On April 9, 2019, Senvion, a German wind turbine manufacturer and a significant customer of Woodward’s renewables business, announced that it filed for self-administration insolvency proceedings and declared it would be exploring options for the sale or partial liquidation of the company. On September 16, 2019, Senvion agreed on exclusive talks with Siemens Gamesa over the sale of a substantial part of its business consisting of certain services and onshore assets in Europe. Concurrent with this announcement, Woodward management concluded that the remainder of the Senvion business would not emerge from insolvency and therefore, in the fourth quarter of fiscal year 2019, Woodward impaired all of its accounts receivable from Senvion as well as inventory and certain other current assets held specifically for Senvion programs. The total amount of the impairment charged to both selling, general and administrative and cost of goods sold in the fourth quarter of fiscal year 2019 was $ 12,601 .

Segment Information
Segment Information	Note 22. 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. Woodward L’Orange has been included in Woodward’s Industrial segment results since the Closing. 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, 2019 2018 2017 Segment external net sales: Aerospace $ 1,880,520 $ 1,557,988 $ 1,342,339 Industrial 1,019,677 767,885 756,346 Total consolidated net sales $ 2,900,197 $ 2,325,873 $ 2,098,685 Segment earnings: Aerospace (2) $ 389,126 $ 308,553 $ 264,362 Industrial (2) 93,521 49,894 80,659 Nonsegment expenses (1)(2) ( 119,447 ) ( 100,078 ) ( 58,359 ) Interest Expense, net (2) ( 42,588 ) ( 38,791 ) ( 33,915 ) Consolidated earnings before income taxes $ 320,612 $ 219,578 $ 252,747 (1) Nonsegment expenses for the fiscal year ended September 30, 2018 includes restructuring charges of $ 17,013 .

On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively. 2. Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment. 3. Gross margin represents net sales less cost of goods sold. 4. Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019. 5. Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible. 6. Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively. 7. Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 . 8. The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions. 9. In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation. 2019 Fiscal Quarters First Second Third Fourth Segment external net sales: Aerospace (1) $ 392,887 $ 482,954 $ 498,775 $ 505,904 Industrial (2) 259,924 275,890 253,230 230,633 Total $ 652,811 $ 758,844 $ 752,005 $ 736,537 Segment earnings: Aerospace $ 72,854 $ 101,722 $ 103,238 $ 111,312 Industrial (3) 29,169 27,128 26,240 10,984 Nonsegment expenses (4)(5) ( 29,001 ) ( 27,496 ) ( 26,713 ) ( 36,237 ) Interest expense, net (8) ( 11,507 ) ( 11,186 ) ( 10,451 ) ( 9,444 ) Consolidated earnings before income taxes $ 61,515 $ 90,168 $ 92,314 $ 76,615 2018 Fiscal Quarters First Second Third Fourth Segment external net sales: Aerospace $ 305,905 $ 386,343 $ 404,612 $ 461,128 Industrial (2) 164,243 161,906 183,505 258,231 Total $ 470,148 $ 548,249 $ 588,117 $ 719,359 Segment earnings: Aerospace $ 45,241 $ 74,656 $ 83,887 $ 104,769 Industrial (3) 19,781 10,687 10,943 8,483 Nonsegment expenses (5)(6)(7) ( 19,026 ) ( 28,344 ) ( 30,699 ) ( 22,009 ) Interest expense, net (8) ( 8,509 ) ( 8,352 ) ( 9,714 ) ( 12,216 ) Consolidated earnings before income taxes $ 37,487 $ 48,647 $ 54,417 $ 79,027 Notes: 1.

Operations and Summary of Sig_2

Operations and Summary of Significant Accounting Policies (Policy)	12 Months Ended
	Sep. 30, 2019
Accounting Policies
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 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, wind turbines, including converters and power grid related equipment, industrial diesel, gas, bio-diesel 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.
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 $ 1,018 in fiscal year 2019, and $ 1,608 in fiscal year 2018, and $ 651 in fiscal year 2017.
Revenue recognition	Revenue recognition : Effective October 1, 2018, Woodward adopted the new revenue recognition guidance of ASC 606. For discussion of the impacts of the adoption of ASC 606 on our revenue recognition policy and related critical accounting estimates, see Note 3, 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. Cash and cash equivalents are maintained with multiple financial institutions. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. Woodward holds cash and cash equivalents at financial institutions in excess of amounts covered by the Federal Depository Insurance Corporation (the “FDIC”), sometimes invests excess cash in money market funds or other highly liquid investments not insured by the FDIC, and holds cash and cash equivalents outside the United States that are not insured by the FDIC.
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, and current economic conditions. 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. Consistent with common business practice in China, Woodward’s Chinese subsidiary accepts from Chinese customers, in settlement of certain customer accounts receivable, bankers’ acceptance notes issued by Chinese banks that are believed to be creditworthy. 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. The issuing financial institution is the obligor, not Woodward’s customers. Upon Woodward’s acceptance of a banker’s acceptance note from a customer, such customer has no further obligation to pay Woodward for the related accounts receivable balance. Woodward only accepts bankers’ acceptance notes issued by banks that are believed to be creditworthy and to which the credit risks associated with the bankers’ acceptance notes are believed to be minimal. For discussion of the impacts of the adoption of ASC 606 on our accounts receivable policy and 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. For discussion of Woodward’s accounting policy for inventory provided by customers to Woodward, which will be integrated into final products sold to those customers, see Note 3, Revenue.
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, 2019 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 year s to five year s.
Purchase accounting	Purchase accounting: Business combinations are accounted for using the purchase method of accounting. Under the purchase method, assets and liabilities, including intangible assets, are recorded at their fair values as of the acquisition date. Acquisition costs in excess of amounts assigned to assets acquired and liabilities assumed are recorded as goodwill. Transaction-related costs associated with business combinations are expensed as incurred.
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 tests consist 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 goodwill impairment testing it has recorded no impairment charges in the year ended September 30, 2019 or since the goodwill was originally recognized.
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 amortizable 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. Amortizable 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, 2019 or since the other intangibles were originally recorded. Estimated lives over which intangible assets are amortized at September 30, 2019 were as follows: Backlog 1 year Customer relationships and contracts 9 - 30 years Intellectual property 10 - 17 years Process technology 8 - 30 years Other 3 - 15 years Woodward has one other indefinitely lived intangible asset consisting of the Woodward L’Orange tradename. The Woodward L’Orange tradename 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 tradename 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. Based on the results of the Woodward L’Orange impairment testing, it has recorded no impairment charges in the year ended September 30, 2019 or since the intangible asset was originally recognized.
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 groups carrying amount and its estimated fair value. There were no impairment charges recorded in fiscal years 2019, 2018 or 2017.
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.”
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. To mitigate interest rate risk, the Company has utilized derivative instruments, such as treasury lock agreements to lock in fixed rates on future debt issuances, which qualify as cash flow or fair value hedges to mitigate the risk of variability in cash flows related to future interest payments attributable to changes in the designated benchmark rate. The Company records all such interest rate hedge instruments on the Consolidated Balance Sheets at fair value. Cash flows related to the instrument designated as a qualifying hedge are reflected in the accompanying Consolidated Statements of Cash Flows in the same categories as the cash flows from the items being hedged. Accordingly, cash flows relating to the settlement of interest rate derivatives hedging the forecasted future interest payments on debt have been reflected upon settlement as a component of financing cash flows. The resulting gain or loss from such settlement is deferred to other comprehensive income and reclassified to interest expense over the term of the underlying debt. This reclassification of the deferred gains and losses impacts the interest expense recognized on the underlying debt that was hedged and is therefore reflected as a component of operating cash flows in periods subsequent to settlement. The periodic settlement of interest rate derivatives hedging outstanding variable rate debt is recorded as an adjustment to interest expense and is therefore reflected as a component of operating cash flows. 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 the spot remeasurement its Euro denominated intercompany loans, Woodward has entered into derivative instruments in fair value hedging relationships, and derivative instruments in cash flow hedging relationships 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 its Euro denominated intercompany loans. 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 .
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. The fair value of investments in the deferred compensation program are adjusted to fair value based on the quoted market prices for the investments in the various mutual funds owned. The fair value of the long-term notes from municipalities are estimated based on a model that discounts future principal and interest payments received at interest rates available to the Company at the end of the period for similarly rated municipal notes of similar maturity. The fair value of term deposits are estimated based on a model that discounts future principal and interest payments received at interest rates available to the Company at the end of the period for similar term deposits with the same maturity in the same jurisdictions. The fair value of the 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. The fair value of long-term debt is estimated based on a model that discounts future principal and interest payments at interest rates available to the Company at the end of the period for similar debt with the same maturity. Further information on the fair value of financial instruments can be found at Note 7, Financial instruments and fair value measurements . 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.
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.
Reclassifications	Reclassifications: Certain amounts at the Consolidated Balance Sheet as of September 30, 2018 and the Consolidated Statement of Cash Flows for the years ended September 30, 2018 and 2017 have been reclassified in order to conform to the current year presentation under ASU 2014-09, “Revenue from Contracts with Customers” (see Note 3, Revenue ) . Certain amounts at the Consolidated Statement of Earnings for the fiscal years ended September 30, 2018 and September 30, 2017 have been reclassified in order to conform to the current year presentation under ASU 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (see Note 2, New accounting standards ).

The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory. (2) The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.” (3) Woodward recorded customer funding of product engineering and development identified as material rights as current and noncurrent deferred revenue contract liabilities included in “Accrued liabilities” and “Other liabilities.” The related customer funded product engineering and development costs were capitalized as costs to fulfill a contract, to the extent of the contractually committed customer funded payments, and are recorded as “Other assets.” (4) The net book value of the backlog and customer relationships and contracts intangible assets was adjusted concurrent with the change in the timing of the associated revenue, resulting in a reduction in the net book value of these assets as of the date of adoption. (5) The value of tax assets and tax liabilities was impacted by the change in timing of the recognition of assets and liabilities within tax jurisdictions. T he following schedule quantifies the impact of adopting ASC 606 on the Consolidated Statements of Earnings for the fiscal year ended September 30, 2019. The effect of the new standard represent the increase (decrease) in the line item based on the adoption of ASC 606. Year Ended September 30, 2019 Under previous standard Effect of ASC 606 As reported Net sales $ 2,790,557 $ 109,640 $ 2,900,197 Costs and expenses: Cost of goods sold 2,088,087 104,567 2,192,654 Selling, general, and administrative expenses 211,307 ( 102 ) 211,205 Research and development costs 160,402 ( 1,295 ) 159,107 Interest expense 44,001 - 44,001 Interest income ( 1,413 ) - ( 1,413 ) Other expense (income), net ( 25,969 ) - ( 25,969 ) Total costs and expenses 2,476,415 103,170 2,579,585 Earnings before income taxes 314,142 6,470 320,612 Income tax expense 60,175 835 61,010 Net earnings $ 253,967 $ 5,635 $ 259,602 Earnings per share Basic earnings per share $ 4.10 $ 0.09 $ 4.19 Diluted earnings per share $ 3.94 $ 0.08 $ 4.02 Weighted Average Common Shares Outstanding (Note 4): Basic 61,950 61,950 Diluted 64,498 64,498 The adoption of ASC 606 resulted in an increase to net sales and cost of goods sold primarily due to the recognition of noncash consideration in the form of customer supplied inventory and the accelerated recognition of revenue and associated cost of goods sold for over time contracts, which would have been recognized at a point in time under the previous standard. The increases were offset by decreases in revenue and cost of goods sold related to the deferral of amounts due from customers recognized as material rights and over time contracts recognized as of the date of adoption, both of which would otherwise have been recognized as revenue during the periods under the previous standard. The following schedule quantifies the impact of adopting ASC 606 on the Consolidated Balance Sheet as of September 30, 2019. The effect of the new standard represents the increase (decrease) in the line item based on the adoption of ASC 606.

On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively. 2. Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment. 3. Gross margin represents net sales less cost of goods sold. 4. Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019. 5. Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible. 6. Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively. 7. Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 . 8. The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions. 9. In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation.

[1]	The adoption of ASC 606 changed the revenue recognition practices for a number of revenue generating activities across Woodward’s businesses, although the most significant impacts are concentrated in product being produced for customers that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and MRO. The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory.
[2]	The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.”

[1]	On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[2]	Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[3]	Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.
[4]	Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[5]	Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.
[6]	Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .
[7]	The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.
[8]	In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation.

[1]	The adoption of ASC 606 changed the revenue recognition practices for a number of revenue generating activities across Woodward’s businesses, although the most significant impacts are concentrated in product being produced for customers that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and MRO. The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory.
[2]	The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.”

[1]	The adoption of ASC 606 changed the revenue recognition practices for a number of revenue generating activities across Woodward’s businesses, although the most significant impacts are concentrated in product being produced for customers that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and MRO. The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory.
[2]	The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.”
[3]	The value of tax assets and tax liabilities was impacted by the change in timing of the recognition of assets and liabilities within tax jurisdictions. T
[4]	The net book value of the backlog and customer relationships and contracts intangible assets was adjusted concurrent with the change in the timing of the associated revenue, resulting in a reduction in the net book value of these assets as of the date of adoption.
[5]	Woodward recorded customer funding of product engineering and development identified as material rights as current and noncurrent deferred revenue contract liabilities included in “Accrued liabilities” and “Other liabilities.” The related customer funded product engineering and development costs were capitalized as costs to fulfill a contract, to the extent of the contractually committed customer funded payments, and are recorded as “Other assets.”

[1]	On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[2]	Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[3]	Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.
[4]	Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[5]	Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.
[6]	Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .
[7]	The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.
[8]	In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation.

On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.

[2]

Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.

The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[3]	In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation.
[4]	Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.
[5]	Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[6]	Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.
[7]	Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .
[8]	The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.

[1]	Component parts include items that can be sold separately as finished goods or included in the manufacture of other products.
[2]	On October 1, 2018, the Company adopted ASC 606, which resulted in the recording of certain customer supplied inventory and the reduction of certain on-hand inventory for which control has transferred to the customer. Refer to Note 3, Revenue, for further details.
[3]	The adoption of ASC 606 changed the revenue recognition practices for a number of revenue generating activities across Woodward’s businesses, although the most significant impacts are concentrated in product being produced for customers that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and MRO. The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory.
[4]	The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.”

Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.

[2]

Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.

[3]

Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.

[4]

Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.

Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .

The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.

[1]	On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[2]	Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[3]	Related to the L’Orange Acquisition, on May 31, 2018 Woodward issued an aggregate principal amount of $ 400,000 of senior unsecured notes in a series of private placement transactions and borrowed $ 167,420 under our revolving credit agreement to fund the acquisition.
[4]	Segment earnings includes the impact of retrospectively applying ASU 2017-07. See Note 2, New Accounting Standards for further details.
[5]	Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.
[6]	Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[7]	Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.
[8]	Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .
[9]	The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.
[10]	To correct the ASC 606 adoption errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[11]	Net Industrial segment sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,825 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[12]	Industrial segment earnings for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[13]	Nonsegment expenses for the fiscal year ended September 30, 2018 includes restructuring charges of $ 17,013 . See Note 15, Accrued liabilities for further details.

[1]	The adoption of ASC 606 changed the revenue recognition practices for a number of revenue generating activities across Woodward’s businesses, although the most significant impacts are concentrated in product being produced for customers that have no alternative use to Woodward and Woodward has an enforceable right to payment with a profit, and MRO. The revenue related to these activities, which previously was accounted for on a point in time basis, is now required to use an over time model because the associated contracts meet one or more of the mandatory criteria established in ASC 606, as described above, and are included as current unbilled receivables in “Accounts receivable” and noncurrent unbilled receivables in “Other assets.” The change in the timing of revenue recognized in connection with over time contracts similarly changed the timing of manufacturing cost recognition and certain engineering and development costs, which are reflected as a reduction to inventory.
[2]	The value of noncash consideration in the form of exchanged products and other customer provided inventory is reflected in “Inventories,” and in contract liabilities, which are included in “Accrued liabilities.”
[3]	Woodward recorded customer funding of product engineering and development identified as material rights as current and noncurrent deferred revenue contract liabilities included in “Accrued liabilities” and “Other liabilities.” The related customer funded product engineering and development costs were capitalized as costs to fulfill a contract, to the extent of the contractually committed customer funded payments, and are recorded as “Other assets.”

Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.

[1]	On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[2]	Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[3]	Results for the first through fourth quarters of fiscal year 2019 include, Duarte move related costs of $ 6,963 , $ 9,161 , $ 7,035 , and $ 3,930 , respectively. Results for the second, third and fourth quarters of fiscal year 2018, include, as applicable, pre-tax Duarte move related costs and L’Orange acquisition transaction and integration costs of $ 1,525 , $ 5,134 and $ 4,714 , respectively.
[4]	Results for the first through third quarters of fiscal year 2019 include pre-tax non-cash charges of $ 9,511 , $ 8,985 , $ 2,604 , respectively, as compared to the third and fourth quarters of fiscal year 2018, which include pre-tax non-cash charges of $ 8,299 and $ 26,086 , respectively. These costs are associated with the purchase accounting impacts related to the revaluation of the L’Orange inventory recognized in cost of goods sold and the amortization of the backlog intangible.
[5]	Results for the fourth quarter of fiscal year 2019 include pre-tax, non-cash charges of $ 12,601 related to the impairment of receivables, inventory and certain other assets in connection with Senvion, a significant customer of Woodward renewables business, which declared insolvency in fiscal year 2019.
[6]	Results for the third quarter of fiscal year 2018 include the (i) pre-tax cost associated with an at-the-money forward option of $ 5,543 , (ii) pre-tax warranty and indemnity insurance costs associated with the acquisition of L’Orange of $ 4,293 , and (iii) pre-tax German real estate transfer tax costs associated with the acquisition of L’Orange of $ 3,385 .
[7]	The second quarter of fiscal year 2018 includes pre-tax restructuring charges totaling $ 17,013 , the majority of which relate to the Company’s decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado. The remaining restructuring charges recognized during the quarter consist of workforce management costs related to aligning the Company’s industrial turbomachinery business with current market conditions.
[8]	In the first and third quarters of fiscal year 2018, Woodward recognized a tax expense of $ 14,778 and $ 3,671 , respectively, and tax benefit of $ 7,589 in the fourth quarter of fiscal year 2018, related to the transition impacts of the change in U.S. tax legislation in December 2017. In the third quarter of fiscal year 2019 , Woodward recognized additional income tax expense of $ 10,588 related to the repatriation tax on deferred foreign income related to the December 2017 U.S. Tax legislation.
[9]	To correct the ASC 606 adoption errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
[10]	Net Industrial segment sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,825 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.

[1]	On June 1, 2018, Woodward acquired L’Orange. Net sales attributable to L’Orange were $ 87,680 , $ 87,986 , $ 78,517 , and $ 77,826 in the first through fourth quarters of fiscal year 2019, respectively, as compared to $ 24,878 and $ 78,027 in the third and fourth quarters of fiscal year 2018, respectively.
[2]	Woodward adopted ASC 606 on October 1, 2018 and elected the modified retrospective transition method. The quarterly results for periods prior to fiscal year 2019 were not adjusted for the new standard. Subsequent to the adoption of ASC 606, Woodward’s management identified an inconsistency in the application of ASC 606. The inconsistency resulted in errors that were cumulatively not material in determining the percentage of completion calculation on over time product revenue recognition, which caused the Condensed Consolidated Financial Statements for the quarters ended December 31, 2018 and March 31, 2019, as well as the cumulative impact of the adoption of ASC 606 on the Condensed Consolidated Balance Sheet as of October 1, 2018, to be misstated by amounts that management concluded were not material (“ASC 606 adoption errors”). To correct the errors for the three-months ended December 31, 2018 and for the three and six-months ended March 31, 2019, Woodward made an out-of-period correction in the three-months ended June 30, 2019. The correction resulted in increases to net sales of $ 13,614 , earnings before income taxes of $ 8,041 , net earnings of $ 6,037 , and diluted earnings per share of $ 0.09 for the three-months ended June 30, 2019, the majority of which relates to Woodward’s Aerospace segment.
