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 enhances the global quality of life and sustainability by optimizing energy use through improved efficiency and lower emissions.  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 energy markets.  The precise and efficient control of energy, including fluid and electrical energy, combustion, and motion, is a growing requirement in the markets it 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, replacement and other service support for its installed products.
	Woodward’s components and integrated systems optimize performance of commercial aircraft, defense aircraft, ground vehicles and other equipment, gas and steam turbines, wind turbines, including converters and power grid related equipment, industrial diesel, gas, alternative and dual fuel reciprocating engines, and electrical power systems.  Woodward’s innovative fluid energy, combustion control, electrical energy, and motion 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 doubtful accounts, net realizable value of inventories, cost of sales incentives, 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 vary materially from Woodward’s 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.  Translation adjustments are accumulated with other comprehensive (loss) 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 of the assets and liabilities of its domestic and foreign subsidiaries, are denominated in foreign currencies.  Selling, general, and administrative expenses include net foreign currency losses of $2,738 in fiscal year 2013 and $480 in fiscal year 2012, and gains of $575 in fiscal year 2011.
	Revenue recognition:  Woodward recognizes revenue upon shipment or delivery of products or services and when collectability is reasonably assured.  Delivery is upon completion of manufacturing, customer acceptance, and the transfer of the risks and rewards of ownership.  In countries whose laws provide for retention of some form of title by sellers, enabling recovery of goods in the event of customer default on payment, product delivery is considered to have occurred when the customer has assumed the risks and rewards of ownership of the products.
	Occasionally, Woodward transfers title of product to customers, but retains substantive performance obligations such as completion of product testing, customer acceptance or in some instances regulatory acceptance.  Revenue is deferred until the performance obligations are satisfied.  In addition, service revenue, which accounts for less than 1% of Woodward’s net sales, is also recognized upon completion of applicable performance obligations.
	Certain Woodward products include incidental software or firmware essential to the performance of the product as designed, which are treated as units of accounting associated with the related tangible product with which the software is included.  Woodward does not sell software on a standalone basis, although software upgrades, if any, are generally paid for by the customer.
	Product freight costs are included in cost of goods sold.  Freight costs charged to customers are included in net sales.
	Taxes collected from customers and remitted to government authorities are excluded from revenue and are recorded as liabilities until the taxes are remitted to the appropriate U.S. or foreign government authority.
	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 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 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”) and sometimes invests excess cash in money market funds not insured by the FDIC.
	Accounts receivable:  Almost all Woodward’s sales are made on credit and result in accounts receivable, which are recorded at the amount invoiced.  In the normal course of business, not all accounts receivable are collected and, therefore, an allowance for losses of accounts receivable is provided equal to the amount that Woodward believes ultimately will not be collected.  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 in establishing the amount of its allowance.  Accounts receivable 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.
	Consistent with business practice common in China, Woodward’s Chinese subsidiary has accepted in settlement of certain customer accounts receivable from Chinese customers’ bank drafts authorized by large, creditworthy Chinese banks.  These bank drafts represent a promise to pay the balance of the receivable at a future date, albeit under payment terms that can be longer than traditional payment terms.  At September 30, 2013 and September 30, 2012, Woodward had bank drafts of $72,954 and $40,312, respectively, recorded as accounts receivable on its Consolidated Balance Sheets.  Woodward only accepts bank drafts authorized by large, creditworthy banks as to which the credit risk associated with the bank draft is assessed to be minimal.
	Inventories:  Inventories are valued at the lower of cost or market, with cost being determined using methods that approximate a first-in, first-out basis.
	Customer deposits are recorded against inventory when the right of offset exists.  There were no customer deposits included in inventory as of September 30, 2013 and 2012.  All other customer deposits are recorded in accrued liabilities.
	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.  Certain buildings and improvements are depreciated using the declining-balance 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, 2013 were as follows:
	Land improvements	5	-	40	years
	Buildings and improvements	5	-	40	years
	Leasehold improvements	1	-	40	years
	Machinery and production equipment	3	-	15	years
	Computer equipment and software	2	-	10	years
	Office furniture and equipment	2	-	15	years
	Other	1	-	13	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 to five years.
	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.
	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 would more likely than not reduce the fair value of a reporting unit below its carrying amount.  Based on the relevant U.S. GAAP authoritative guidance, Woodward sometimes 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 including 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.  There was no impairment charge recorded in fiscal years 2013, 2012, or 2011.
	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.  All of Woodward’s intangibles have an estimated useful life and are being amortized using patterns that reflect the periods over which the economic benefits of the assets are expected to be realized.  Impairment losses are recognized if the carrying amount of an intangible is both not recoverable and exceeds its fair value.
	Estimated lives over which intangible assets are amortized at September 30, 2013 were as follows:
	Customer relationships	9	-	30	years
	Intellectual property	10	-	17	years
	Process technology	8	-	30	years
	Other	3	-	15	years
	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 was no impairment charge recorded in fiscal years 2013, 2012 or 2011.
	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 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 Sheet 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 market risks that arise from transactions entered into in the normal course of business.  The Company has historically 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 balance sheet 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, Woodward will enter into foreign currency exchange rate contracts to hedge against changes in foreign currency exchange rates on liabilities expected to be settled at a future date.  Woodward has historically not designated these transactions as accounting hedges.  The fair value of foreign currency exchange rate contracts held at the end of the period are recognized in the balance sheet and the unrealized gains or losses are recorded to “Other (income) expense, net” in the Consolidated Statements of Earnings.  Upon settlement of foreign currency exchange rate contracts, any unrealized gains or losses previously recognized are reversed and the realized gain or loss is recorded to “Other (income) expense, net” in the Consolidated Statement of Earnings.  Further information on foreign currency exchange rate contracts can be found at Note 6, Derivative instruments and hedging activities.
	Financial instruments:  The Company’s financial instruments include cash and cash equivalents, investments in the deferred compensation program 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 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 5, 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.  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.  Accumulated benefit obligation differs from projected benefit obligation in that it includes no assumption about future compensation levels.

Recent Accounting Pronouncements	'
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 February 2013, the FASB issued ASU 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.”  ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in financial statements; however, the amendments require companies to provide information about the amounts reclassified out of accumulated comprehensive income by component.  ASU 2013-02 requires a company to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated comprehensive income by respective line items of net income, but only if the amount so reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period.  For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, a company is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts.  ASU 2013-02 is effective prospectively for annual reporting periods beginning after December 15, 2012 (fiscal year 2014 for Woodward).  As the requirements of ASU 2013-02 are disclosure related only, it is not expected to have a material impact on Woodward’s Consolidated Financial Statements.
	In September 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment.”  ASU 2011-08 allows companies to perform a “qualitative” assessment to determine whether or not the current two-step quantitative testing method, in which a company compares the fair value of reporting units to its carrying amount including goodwill, must be followed.  If a qualitative assessment indicates that it is more-likely-than-not that the fair value of a reporting unit is greater than its carrying amount, then the quantitative impairment test is not required.  A company may choose to use the qualitative assessment on none, some, or all if its reporting units or to bypass the qualitative assessment and proceed directly to the two-step quantitative testing method.  ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011 (fiscal year 2013 for Woodward).  The adoption of ASU 2011-08 did not have a material impact on Woodward’s Consolidated Financial Statements.

Earnings Per Share	'
Earnings Per Share	'
	Note 3.  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.
	The following is a reconciliation of net earnings to basic earnings per share and diluted earnings per share:
		Year Ended September 30,
		2013		2012		2011
	Numerator:
	Net earnings	$	145,942	$	141,589	$	132,235
	Denominator:
	Basic shares outstanding		68,392		68,880		68,797
	Dilutive effect of stock options		1,210		1,427		1,343
	Diluted shares outstanding		69,602		70,307		70,140
	Income per common share:
	Basic earnings per share	$	2.13	$	2.06	$	1.92
	Diluted earnings per share	$	2.10	$	2.01	$	1.89
	The following stock option grants were outstanding during the fiscal years ended September 30, 2013, 2012 and 2011, but were excluded from the computation of diluted earnings per share because their inclusion would have been anti-dilutive:
		Year Ended September 30,
		2013		2012		2011
	Options		44		50		684
	Weighted-average option price	$	40.21	$	36.33	$	32.04
	The weighted-average shares of common stock outstanding for basic and diluted earnings per share included the weighted-average treasury stock shares held for deferred compensation obligations of the following:
		Year Ended September 30,
		2013		2012		2011
	Weighted-average treasury stock shares held for deferred compensation obligations		256		295		335

Business_Acquisitions

Business Combinations	'
Business Acquisitions	'
	Note 4.  Business acquisitions
	Woodward has recorded the acquisitions described below using the purchase method of accounting and, accordingly, has included the results of operations of the acquired businesses in its consolidated results as of the date of acquisition.    In accordance with authoritative accounting guidance for business combinations, the respective purchase prices for these acquisitions are allocated to the tangible assets, liabilities, and intangible assets acquired based on their estimated fair values.  The excess purchase price over the respective fair values of assets is recorded as goodwill.  Goodwill is not amortized under U.S. GAAP but is tested for impairment at least annually (See Note 10, Goodwill).
	Duarte Business Acquisition
	On December 27, 2012, Woodward entered into a definitive asset purchase agreement (the “Asset Purchase Agreement”) with GE Aviation Systems LLC (the “Seller”) and General Electric Company for the acquisition of substantially all of the assets and certain liabilities related to the Seller’s thrust reverser actuation systems business located in Duarte, California (the “Duarte Business”) for an aggregate purchase price of $200,000.  The acquisition was completed on December 28, 2012 and, based on customary purchase price adjustments, Woodward paid cash at closing in the amount of $198,900.  The purchase price remains subject to certain additional customary post-closing adjustments.
	The Duarte Business develops and manufactures motion control technologies and platforms, more specifically thrust reverser actuation systems.  The Duarte Business serves customers such as Airbus, Boeing, General Electric, Safran and the U.S. Government.  Its products are used primarily on commercial aircraft such as the Boeing 737, 747 and 777, and the Airbus A320.  The Duarte Business is being integrated into Woodward’s Aerospace segment.
	The Duarte Business employs approximately 350 people, of which approximately 65% are union employees.  The collective bargaining agreements with Woodward’s union employees are generally renewed through contract renegotiations prior to the contract expiration date.  The International Union, United Automobile, Aerospace and Agricultural Implement Workers of America and Local No. 509 (the “Duarte Union”) contract, which covers the unionized Duarte Business employees, was to expire on May 25, 2013.  During the third quarter of fiscal year 2013, a new collective bargaining agreement was negotiated, which will expire on June 3, 2017.
	The Company believes the Duarte Business provides it with expanded motion control technologies and platforms, and that there will be operating synergies and significant opportunities to share technologies and leverage the customer base.  Goodwill recorded in connection with the acquisition of the Duarte Business, which is deductible for income tax purposes, represents the estimated value of such future opportunities, the value of potential expansion with new customers, the opportunity to further develop sales opportunities with new and acquired Duarte Business customers, and other synergies expected to be achieved through the integration of the Duarte Business into Woodward’s Aerospace segment.
	The preliminary purchase price of the Duarte Business is as follows:
	Cash paid to Seller	$	198,900
	Less cash acquired		-40
	Total preliminary purchase price	$	198,860
	The allocation of the purchase price to the assets acquired and liabilities assumed was accounted for under the purchase method of accounting in accordance with ASC Topic 805, “Business Combinations.”  Assets acquired and liabilities assumed in the transaction were recorded at their estimated acquisition date fair values, while transaction costs associated with the acquisition were expensed as incurred.  Woodward’s preliminary allocation was based on an evaluation of the appropriate fair values and represents management’s best estimate based on available data.
	Woodward is currently working with the Seller to finalize purchase price adjustments customary to these types of transactions and, therefore, has not finalized the valuations of all assets acquired and liabilities assumed.  Changes to the valuations of the assets and liabilities acquired resulted in insignificant changes to Woodward’s previously reported earnings and therefore prior quarters have not been restated.
	The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of the acquisition of the Duarte Business:
	Accounts receivable	$	14,245
	Inventories		30,149
	Other current assets		10,370
	Property, plant, and equipment		11,804
	Goodwill		88,477
	Intangible assets		86,700
	Other noncurrent assets		18,097
	Total assets acquired		259,842
	Other current liabilities		29,676
	Other noncurrent liabilities		31,306
	Total liabilities assumed		60,982
	Net assets acquired	$	198,860
	Assumed liabilities include $4,758 and $17,939 of current and long-term performance obligations, respectively, for contractual commitments that are expected to result in future economic losses.
	The Asset Purchase Agreement included commitments for the Duarte Business to continue to provide services to the Seller unrelated to the core business acquired, for which Woodward will be paid by the Seller. Assumed liabilities include $12,985 and $13,215 of current and long-term performance obligations, respectively, for services to be provided to the Seller, offset by $8,103 and $18,097 of current and long-term assets, respectively, related to contractual payments due from the Seller.
	In connection with the acquisition of the Duarte Business, Woodward did not assume the postretirement benefit obligations of the Duarte Business’ defined benefit pension plan.  Under the terms of the Asset Purchase Agreement, Woodward was obligated to establish a new defined benefit pension plan for the Duarte Business employees who were beneficiaries of the Seller’s defined benefit pension plan.  Woodward completed the establishment of the new defined benefit pension plan during the third quarter of fiscal year 2013.  Woodward’s new defined benefit pension plan provides for similar benefits as those provided by the Seller.  For more information about the new defined benefit pension plan for the Duarte Business, see Note 18, Retirement benefits.
	A summary of the estimated intangible assets acquired, weighted-average useful lives, and amortization methods follows:
		Estimated Amounts		Weighted-Average Useful Life		Amortization Method
	Customer relationships and contracts	$	74,000	20	years	Straight-line
	Process technology		5,000	25	years	Straight-line
	Backlog		7,700	3	years	Accelerated
	Total	$	86,700
	Future amortization expense associated with the acquired intangibles is expected to be:
	Year Ending September 30:
	2014	$	5,944
	2015		4,382
	2016		4,047
	2017		4,047
	2018		4,047
	Thereafter		57,715
		$	80,182
	Net sales for the Duarte Business subsequent to the date it was acquired by Woodward were $111,261 for fiscal year ended September 30, 2013.  Earnings of the Duarte Business subsequent to the date it was acquired by Woodward for the fiscal year ended September 30, 2013 were slightly accretive to the consolidated net earnings of Woodward.
	Pro forma results for Woodward giving effect to the acquisition of the Duarte Business
	The following unaudited pro forma financial information presents the combined results of operations of Woodward and the Duarte Business as if the acquisition had occurred as of October 1, 2011, the beginning of fiscal year 2012.  The pro forma information is presented for information purposes only and is not indicative of the results of operations that would have been achieved if the acquisition and the borrowings used to finance it had taken place at the beginning of fiscal year 2012.  The pro forma information combines the historical results of Woodward with the historical results of the Duarte Business for that period.
	Prior to the acquisition of the Duarte Business,  the Duarte Business was a wholly owned business of the Seller, and as such was not a stand-alone entity for financial reporting purposes.  Accordingly, the historical operating results of the Duarte Business may not be indicative of the results that might have been achieved, historically or in the future, if the Duarte Business had been a stand-alone entity.  The unaudited pro forma results for the fiscal years ended September 30, 2013 and September 30, 2012 include amortization charges for acquired intangible assets, eliminations of intercompany transactions, adjustments for depreciation expense for property, plant and equipment, adjustments for acquired performance obligations, transaction costs incurred, adjustments to interest expense, and related tax effects.
	The unaudited pro forma results for the fiscal years ended September 30, 2013 and September 30, 2012, compared to the actual results reported in these Consolidated Financial Statements, follow:
		Year Ended September 30, 2013				Year Ended September 30, 2012
		As reported		Pro forma		As reported		Pro forma
	Net sales	$	1,935,976	$	1,966,376	$	1,865,627	$	1,978,169
	Net earnings		145,942		152,271		141,589		131,412
	Earnings per share:
	Basic earnings per share	$	2.13	$	2.23	$	2.06	$	1.91
	Diluted earnings per share		2.10		2.19		2.01		1.87
	These pro forma results do not reflect the favorable impact of various long-term agreements with customers of the Duarte Business that were renegotiated by the Seller prior to the acquisition and effective on or before January 1, 2013.  Collectively, the renegotiation of the agreements would have had a significant positive impact on prior operating results of the Duarte Business if implemented earlier.
	The Company incurred transaction costs of $1,944 for the fiscal year ended September 30, 2013, which are included in “Selling, general and administrative expenses” in the Consolidated Statements of Earnings.
	IDS Acquisition
	During the third quarter of fiscal year 2011, Woodward acquired all of the outstanding stock of Integral Drive Systems AG and its European companies, including their respective holding companies (“IDS”), and the assets of IDS’s business in China (together the “IDS Acquisition”) for an aggregate purchase price of approximately $48,412 paid to the sellers.
	IDS is a developer and manufacturer of innovative power electronic systems predominantly in utility scale wind turbines and photovoltaic power plants.  IDS also offers key products for power distribution and marine propulsion systems.  In addition to wind turbines and photovoltaic plants, its products are used in offshore oil and gas platforms, energy storage and distribution systems, and a variety of industrial applications.  IDS has been integrated into Woodward’s Energy segment.
	The purchase price of the IDS Acquisition is as follows:
	Cash paid to sellers	$	48,412
Less cash acquired		-1,251
Total purchase price		47,161
Less marketable securities acquired		-8,463
Price paid for business assets	$	38,698
The allocation of the purchase price to the assets acquired and liabilities assumed was finalized as of March 31, 2012. 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 summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of the IDS Acquisition:
Current assets	$	14,627
Investments in marketable securities		8,463
Property, plant, and equipment		1,954
Goodwill		24,188
Intangible assets		11,882
Total assets acquired		61,114
Other current liabilities		5,505
Warranty accrual		2,250
Postretirement benefits		434
Deferred tax liabilities		2,472
Other tax - noncurrent		3,292
Total liabilities assumed		13,953
Net assets acquired	$	47,161
During the fiscal year ended September 30, 2012, there were no changes to the initial valuation of assets acquired and liabilities assumed in the IDS Acquisition.  The fair value of warranty liabilities assumed represents the estimated costs to provide service for contractual warranty obligations on products sold by IDS and IDS’s business in China prior to the IDS Acquisition.  The fair value of “Other tax – noncurrent” represents the estimated value of gross unrecognized tax benefits assumed.
In connection with the IDS Acquisition, Woodward acquired various marketable securities, which are not classified as cash equivalents under U.S. GAAP.  These marketable securities were sold during the fiscal quarter ended June 30, 2011 and reinvested into cash and cash equivalents consistent with Woodward’s internal investment and risk management policies.  Losses on the sale of marketable securities were included in “Other (income) expense, net” in the Consolidated Statement of Earnings for the year ended September 30, 2011.
Also, in connection with the IDS Acquisition, Woodward assumed the net postretirement benefit obligations of several Swiss statutory retirement plans which are considered to be defined benefit plans under U.S. GAAP.
A summary of the intangible assets acquired, weighted-average useful lives and amortization methods follows:
	Estimated Amounts		Weighted-Average Useful Life		Amortization Method
Customer relationships and contracts	$	3,452	9	years	Straight-line
Process technology		7,752	8.5	years	Straight-line
Backlog		678	2.5	years	Straight-line
Total	$	11,882	8	years
The operating results of the IDS Acquisition are included in Woodward’s Consolidated Statements of Earnings and Comprehensive Earnings as of April 15, 2011.  Pro forma financial disclosures were not presented as the IDS Acquisition was not significant to Woodward’s financial position or results of operations.  Woodward incurred IDS Acquisition related transaction costs of $2,396 during the year ended September 30, 2011, which were included in “Selling, general and administrative expenses” in the Consolidated Statement of Earnings.  No additional IDS Acquisition related transaction costs were incurred in the years ended September 30, 2013 or September 30, 2012.

Financial Instruments and Fair Value Measurements	'
	Note 5.  Financial instruments and fair value measurements
	Financial assets and liabilities recorded at fair value in the Consolidated Balance Sheet are categorized based upon a fair value hierarchy established by U.S. GAAP.
	The table below presents information about Woodward’s financial assets 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.  Woodward had no financial liabilities required to be measured at fair value on a recurring basis as of September 30, 2013 or September 30, 2012.
		At September 30, 2013												At September 30, 2012

	Total financial assets	$	56,841		$	-		$	-		$	56,841		$	69,145	$	-	$	-	$	69,145
	Investments in money market funds: Woodward sometimes invests excess cash in money market funds not insured by the FDIC.  Woodward believes that the investments in money market funds are on deposit with creditworthy financial institutions and that the funds are highly liquid.  The investments in money market funds are reported at fair value, with realized gains from interest income realized in earnings and are included in “Cash and cash equivalents.”  The fair values of Woodward’s investments in money market funds are based on the quoted market prices for the net asset value of the various money market funds.
	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 realized in earnings, and are included in “Cash and cash equivalents.”  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.
	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.”  The trading securities are included in “Other assets.”  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.
	The estimated fair values and carrying costs of financial instruments that are not required to be remeasured at fair value in the Consolidated Balance Sheets were as follows:
				At September 30, 2013						At September 30, 2012
		Fair Value Hierarchy Level		Estimated Fair Value			Carrying Cost			Estimated Fair Value			Carrying Cost
	Assets:
	Notes receivable from municipalities	2			6,718			8,114			-			-
	Liabilities:
	Short-term borrowings	2			-			-			-329			-329
	Long-term debt, including current portion	2			-588,297			-550,000			-443,827			-391,875
	In fiscal year 2013, Woodward received a long-term note from a municipality within the state of Illinois in connection with certain economic incentives related to Woodward’s development of a second campus in the greater-Rockford, Illinois area for its aerospace business.  The fair value of the long-term note 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 municipality notes of the same maturity, which is a level 2 input as defined by the U.S. GAAP fair value hierarchy.  The interest rate used to estimate the fair value of the long-term note was 4.3% at September 30, 2013.
	In fiscal year 2013, Woodward received a long-term note from a municipality within the state of Colorado in connection with certain economic incentives related to Woodward’s development of a new campus at its corporate headquarters in Fort Collins, Colorado.  The fair value of the long-term note 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 municipality notes of the same maturity, which is a level 2 input as defined by the U.S. GAAP fair value hierarchy.  The interest rate used to estimate the fair value of the long-term note was 4.3% at September 30, 2013.
	The fair values of short-term borrowings at variable interest rates are assumed to be equal to their carrying amounts because such borrowings are expected to be repaid or settled for their carrying amounts within a short period of time.
	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 2.0% and 2.1% as of September 30, 2013 and September 30, 2012, respectively.

Derivative Instruments and Hedging Activities	'
	Note 6.  Derivative instruments and hedging activities
	Woodward is exposed to 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 with only creditworthy counterparties.  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.
	Other than the cash flow hedge discussed below, Woodward did not enter into any other derivatives or hedging transactions during the fiscal years ended September 30, 2013 and September 30, 2012.
	Derivatives in fair value hedging relationships
	In 2002, Woodward entered into certain interest rate swaps that were designated as fair value hedges of its long-term debt consisting of senior notes due in October 2011.  The discontinuance of these interest rate swaps resulted in gains that were recognized as a reduction of interest expense over the term of the associated debt (10 years) using the effective interest method.  The unrecognized portion of the gain was presented as an adjustment to long-term debt.
	As of September 30, 2013 and September 30, 2012, there was no remaining unrecognized portion of the gain as it became fully amortized during the quarter ended December 31, 2011.
	Derivatives in cash flow hedging relationships
	In June 2013, in connection with Woodward’s expected refinancing of current maturities on its 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 Topic 815, “Derivatives and Hedging.”    The objective of this derivative instrument is 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 interest payments on a portion of anticipated future debt issuances.  The treasury lock agreement was settled in August 2013 and the resulting gain of $507 was recorded as a reduction to accumulated other comprehensive earnings (“accumulated OCI”) and will be recognized as a decrease to interest expense over a seven-year period.
	In September 2008, the Company entered into treasury lock agreements that qualified as cash flow hedges under authoritative guidance for derivatives and hedging.  The objective of this derivative instrument was to hedge the risk of variability in cash flows related to future interest payments of a portion of the anticipated future debt issuances attributable to changes in the designated benchmark interest rate associated with the expected issuance of long-term debt to acquire Techni-Core, Inc. (“Techni-Core”) and MPC Products Corporation (“MPC Products” and, together with Techni-Core, “MPC”).  The discontinuance of these treasury lock agreements resulted in a gain that is being recognized as a reduction of interest expense over a seven-year period on the hedged Series C and D Notes, which were issued on October 1, 2008, using the effective interest method.  The unrecognized portion of the gain is recorded in accumulated other comprehensive earnings, net of tax.
	In March 2009, Woodward entered into LIBOR lock agreements that qualified as cash flow hedges under authoritative guidance for derivatives and hedging.  The objective of this derivative instrument was to hedge the risk of variability in cash flows over a seven-year period related to future interest payments of a portion of anticipated future debt issuances attributable to changes in the designated benchmark interest rate associated with the then expected issuance of long-term debt to acquire HR Textron Inc. (“HRT”).  The discontinuance of the LIBOR lock agreements resulted in a loss that is being recognized as an increase of interest expense over a seven-year period on the hedged Series E and F Notes, which were issued on April 3, 2009, using the effective interest method.  The unrecognized portion of the loss is recorded in accumulated other comprehensive earnings, net of tax.
	Derivatives in foreign currency relationships
	In September 2010, Woodward entered into a foreign currency exchange rate contract to purchase €39,000 for approximately $52,549 in early December 2010.  An unrealized gain of $579 on this derivative was carried at fair market value in “Other current assets” as of September 30, 2010.  In December 2010, a loss of $1,033 was recorded on the settlement of this forward contract and was recorded in “Other (income) expense, net.”
	The objective of this derivative instrument, which was not designated as an accounting hedge, was to limit the risk of foreign currency exchange rate fluctuations on certain short-term intercompany loan balances.
	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 other comprehensive losses, were a net gain of $71 and a net loss of $607 as of September 30, 2013 and September 30, 2012, respectively.
	The following tables disclose the impact of derivative instruments on Woodward’s Consolidated Statements of Earnings:
			Year ended September 30, 2013

	Foreign currency relationships	Other (income) expense, net		1,612		-		-
			$	1,774	$	-	$	229
	Based on the carrying value of the realized but unrecognized gains and losses on terminated derivative instruments designated as cash flow hedges as of September 30, 2013, Woodward expects to reclassify $99 of net unrecognized losses on terminated derivative instruments from accumulated other comprehensive earnings to earnings during the next twelve months.

	Woodward is developing a second campus in the greater-Rockford, Illinois area for its aerospace business in order to address the growth expected over the next ten years and beyond and to support a substantial number of recently awarded new system platforms, particularly on narrow-body aircraft.  During fiscal year 2013, $1,809 was recorded to land and land improvements in connection with this development.  Included in construction in progress at September 30, 2013 are $15,691 of costs associated with the construction of the second campus, including $444 of capitalized interest.
	Woodward is also developing a new campus at its corporate headquarters in Fort Collins, Colorado to support the continued growth of our energy business by supplementing its existing Colorado manufacturing facilities and corporate headquarters.  During fiscal year 2013, $9,302 was recorded to land and land improvements in connection with this development.  Included in construction in progress at September 30, 2013 are $10,514 of costs associated with the construction of the new campus, including $394 of capitalized interest.
	In addition, in September 2013, Woodward invested $25,602 on a building site in Niles, Illinois, of which $13,535 was recorded to land and land improvements.  The remaining $12,067 is included in construction in progress at September 30, 2013.  Woodward intends to build a new facility on this site for its aerospace business and will relocate some of its operations currently residing in Skokie, Illinois to this new facility.

	On December 28, 2012, Woodward completed the acquisition of the Duarte Business (Note 4, Business acquisitions), which resulted in the recognition of $88,477 in goodwill.  The operations of the Duarte Business are being integrated into Woodward’s Aerospace segment.
	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 would more likely than not reduce the fair value of a reporting unit below its carrying amount.  Based on the relevant U.S. GAAP authoritative guidance, Woodward sometimes 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 units with its carrying amount including 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.
	Uncertainty with respect to U.S. and other government renewable power incentives and economic factors associated with alternate energy sources have resulted in significant overcapacity and financial distress in the renewable power industry.  As  such, the Company made a decision to align its renewable power business appropriately for the current environment and foreseeable future.  In connection with this action, Woodward performed a goodwill impairment test, as of June 30, 2013, on the renewable power systems reporting unit.  This reporting unit is a component of an operating segment within the Energy reportable segment.  The results of the impairment analysis indicated that the fair value of the reporting unit was in excess of its carrying value, and accordingly, no impairment existed.
	Woodward completed its annual goodwill impairment test as of July 31, 2013 during the quarter ended September 30, 2013.  At that date, Woodward determined it was appropriate to aggregate certain components of the same operating segment into a single aggregated 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, and the present value, based on 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 five or 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, 2013 impairment test were discounted using weighted-average cost of capital assumptions ranging from 8.85% to 10.32%.  The terminal values of the forecasted cash flows were calculated using the Gordon Growth Model and assumed an annual compound growth rate after five or ten years of 4.25% or 4.50%.  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 unit’s resulting fair values utilizing a market multiple method.
	The results of Woodward’s goodwill impairment tests performed as of July 31, 2013 indicated the estimated fair value of each reporting unit was substantially in excess of its carrying value, and accordingly, no impairment existed.
	As part of the Company’s ongoing monitoring efforts, Woodward will continue to consider the global economic environment and its potential impact on Woodward’s business in assessing goodwill for possible indications of impairment.  There can be no assurance that Woodward’s estimates and assumptions regarding forecasted cash flows of certain reporting units, the current economic environment, or the other inputs used in forecasting the present value of forecasted cash flows will prove to be accurate projections of future performance.

Credit Facilities and Short-term Borrowings	'
	Note 12.  Credit facilities and short-term borrowings
	As of September 30, 2013, Woodward’s short-term borrowings and availability under its various short-term credit facilities follows:
		Total availability		Outstanding letters of credit and guarantees		Outstanding borrowings		Remaining availability
	Revolving credit facility	$	600,000	$	-4,514	$	-	$	595,486

	Foreign performance guarantee facilities		10,391		-547		-		9,844
		$	638,618	$	-5,061	$	-	$	633,557
	On July 10, 2013, Woodward terminated its $400,000 revolving credit facility (the “2012 Credit Facility”) established under a credit agreement (the “Third Amended and Restated Credit Agreement”) and entered into a new revolving credit agreement (the “Revolving Credit Agreement”) between Woodward and a syndicate of lenders led by Wells Fargo Bank, National Association, as administrative agent.  The Revolving Credit Agreement matures in July 2018.  As compared to the Third Amended and Restated Credit Agreement, the borrowing capacity under the Revolving Credit Agreement increased from $400,000 to $600,000.  Subject to lenders’ participation, the option to expand the commitment remains at $200,000, for a total borrowing capacity of up to $800,000 under the Revolving Credit Agreement.  Borrowings under the Revolving Credit Agreement generally bear interest at LIBOR plus 0.85% to 1.65%.  There were no outstanding borrowings under the Revolving Credit Agreement as of September 30, 2013.
	The Revolving Credit Agreement contains certain covenants customary with such agreements, which are generally consistent with the covenants applicable to Woodward’s long-term debt agreements, and contains customary events of default, including certain cross default provisions related to Woodward’s other outstanding debt arrangements in excess of $60,000, the occurrence of which would permit the lenders to accelerate the amounts due thereunder. In addition, the Revolving Credit Agreement includes the following financial covenants: (i) a maximum permitted leverage ratio for Woodward and its consolidated subsidiaries not to exceed 3.50:1.00, which ratio, subject to certain restrictions, may increase to 4.00:1.00 for the fiscal quarter (and the immediately following fiscal quarter) during which a permitted acquisition occurs and to 3.75:1.00 for the next two succeeding fiscal quarters, and (ii) a minimum consolidated net worth of $800,000, plus 50% of Woodward’s positive net income for the prior fiscal year and plus 50% of Woodward’s net cash proceeds resulting from certain issuances of stock, subject to certain adjustments.
	Woodward’s obligations under the Revolving Credit Agreement are guaranteed by Woodward FST, Inc., Woodward MPC, Inc., and Woodward HRT, Inc., each of which is a wholly owned subsidiary of Woodward.
	In connection with the Revolving Credit Agreement, Woodward incurred $1,651 in financing costs, which are deferred and are being amortized using the straight-line method over the life of the agreement.  Woodward also had remaining $1,529 of deferred financing costs incurred in connection with the 2012 Credit Facility, which have been combined with the financing costs associated with the Revolving Credit Agreement and amortized using the straight-line method over the life of the Revolving Credit Agreement.
	A Chinese subsidiary of Woodward has a local credit facility with the Hong Kong and Shanghai Banking Company under which it has the ability to borrow up to either $22,700, or the local currency equivalent of $22,700.  Any cash borrowings under the local Chinese credit facility are secured by a parent guarantee from Woodward.  The Chinese subsidiary may utilize the local facility for cash borrowings to support its operating cash needs.  Local currency borrowings on the Chinese credit facility are charged interest at the prevailing interest rate offered by the People’s Bank of China on the date of borrowing, plus a margin equal to 25% of that prevailing rate.  U.S. dollar borrowings on the credit facility are charged interest at the lender’s cost of borrowing rate at the date of borrowing, plus 3%.  The Chinese subsidiary had no outstanding cash borrowings against the local credit facility at September 30, 2013 and September 30, 2012.
	Woodward also 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 as of September 30, 2013 and $329 of borrowings outstanding as of September 30, 2012 on Woodward’s other foreign lines of credit and foreign overdraft facilities.

	In October 2008, Woodward entered into a term loan credit agreement (the “2008 Term Loan Credit Agreement”).  During the second quarter of fiscal year 2013, the remaining outstanding indebtedness under the 2008 Term Loan Credit Agreement, which generally bore interest at LIBOR plus 1.00% to 2.25%, was repaid and terminated, without penalty, and the remaining balance of unamortized debt issuance costs of $128 were written off to interest expense.
	Certain financial and other covenants under Woodward's debt agreements contain customary restrictions on the operation of its business.  In the event of non-compliance with these covenants, certain additional restrictions might apply, including restrictions on the Company's ability to pay dividends or make distributions on its capital stock.    Management believes that Woodward was in compliance with the covenants under the long-term debt agreements at September 30, 2013.
	The Notes
	In October 2008, Woodward entered into a note purchase agreement (the “2008 Note Purchase Agreement”) relating to the Series B, C, and D Notes (the “2008 Notes”).  In April 2009, Woodward entered into a note purchase agreement (the “2009 Note Purchase Agreement”) relating to the Series E and F Notes (the “2009 Notes”).
	On October 1, 2013, Woodward entered into a note purchase agreement (the “2013 Note Purchase Agreement” and, together with the 2008 Note Purchase Agreement and the 2009 Note Purchase Agreement, the “Note Purchase Agreements”) 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.  The aggregate principal amount is comprised of the following:
		Amount			Maturity Date		Interest Rate
	Series G notes	$	50,000		15-Nov-20		3.42%
	Series H notes		25,000		15-Nov-23		4.03%
	Series I notes		25,000		15-Nov-25		4.18%
	Series J notes		50,000		15-Nov-20		Floating rate - LIBOR plus 1.25%
	Series K notes		50,000		15-Nov-23		4.03%
	Series L notes		50,000		15-Nov-25		4.18%
		$	250,000
	Woodward issued the Series G, H and I Notes (the “First Closing Notes”) on October 1, 2013 and used the proceeds to repay all of the outstanding balance on the Series B Notes due October 1, 2013.
	Under the terms of the 2013 Note Purchase Agreement, Woodward intends to issue under a delayed draw, the Series J, K and L Notes (the “Second Closing Notes” and, together with the 2008 Notes, 2009 Notes and First Closing Notes, the “Notes”) in an additional $150,000 aggregate principal amount on November 15, 2013.
	Interest on the 2008 Notes and the First Closing Notes is, and interest on the Series K Notes and Series L Notes will be, payable semi-annually on April 1 and October 1 of each year until all principal is paid.  Interest on the 2009 Notes is payable semi-annually on April 15 and October 15 of each year until all principal is paid.  Interest on the Series J Notes will be payable quarterly on January 1, April 1, July 1 and October 1 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 or are expected to be held by multiple institutions.
	Woodward’s obligations under the Notes are, or when issued will be, guaranteed by Woodward FST, Inc., Woodward MPC, Inc., and Woodward HRT, Inc., each of which is a wholly owned subsidiary of Woodward.  Woodward’s obligations under the Notes rank, or when issued will rank, equal in right of payment with all of Woodward’s other unsecured unsubordinated debt, including its outstanding debt under the Line of Credit and revolving credit facility (see Note 12, Credit facilities and short-term borrowings).
	On October 1, 2013, Woodward also entered into amendments to the 2008 Note Purchase Agreement and 2009 Note Purchase Agreement that, among other things, conform certain of the affirmative and negative covenants in the 2008 Note Purchase Agreement and the 2009 Note Purchase Agreement, respectively, to the corresponding covenant provisions in the 2013 Note Purchase Agreement.
	The Note Purchase Agreements 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 Agreements, 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. Further, Woodward’s consolidated net worth must at all times equal or exceed $800,000 plus 50% of Woodward’s consolidated net earnings for each fiscal year beginning with the fiscal year ending September 30, 2013.  The Note Purchase Agreements also contain 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 holders of the respective Notes to accelerate the amounts due.
	Woodward, at its option, is permitted at any time to prepay all, or from time to time to prepay any part of, the then outstanding principal amount of any series of the Notes at 100% of the principal amount of the series of Notes to be prepaid (but, in the case of partial prepayment, not less than $1,000), together with interest accrued on such amount to be prepaid to the date of payment, plus any applicable prepayment compensation amount. The prepayment compensation amount, as to the Notes other than the floating rate Notes, is computed by discounting the remaining scheduled payments of interest and principal of the 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 Notes being prepaid. The prepayment compensation amount, as to the floating rate Notes, generally is computed as a percentage of the principal amount of such the floating rate Notes equal to (a) 2%, on or prior to November 15, 2014, (b) 1%, after November 15, 2014 and on or prior to November 15, 2015, and (c) 0% after November 15, 2015.
	Line of Credit
	In connection with the acquisition of the Duarte Business, on December 21, 2012 Woodward entered into a 364 day uncommitted line of credit with JPMorgan Chase Bank, N.A. (the “Line of Credit”).  The Line of Credit provides for unsecured loans to Woodward of up to $200,000 on a revolving basis.  Loans made under the Line of Credit bear interest at a floating rate based, at the Company’s option, on either the prime rate or an adjusted LIBOR.  The Line of Credit under which Woodward may borrow terminates on December 20, 2013.  There was $200,000 outstanding on the Line of Credit as of September 30, 2013, which consisted of an adjusted LIBOR loan bearing interest at 1.06% and maturing on October 31, 2013.  Subsequently, the Company renewed the loan to extend the maturity to November 15, 2013.  The Company cannot repay the adjusted LIBOR loan prior to the November 15, 2013 maturity date without incurring a prepayment penalty.  Subject to lender participation, Woodward may renew the loan on the Line of Credit for one additional period prior to its termination on December 20, 2013.
	The Line of Credit contains customary terms and conditions, as well as events of default customary for such financing arrangements, including cross-default provisions based on certain covenants and provisions contained in the Third Amended and Restated Credit Agreement the occurrence of which would permit the lenders to accelerate the amounts due thereunder.
	The proceeds from the Line of Credit were used to finance the acquisition of the Duarte Business as discussed in Note 4, Business acquisitions.  The Company incurred no financing fees in association with the Line of Credit.
	Woodward classified the $200,000 outstanding on the Line of Credit as long-term as of September 30, 2013 based on its intention to refinance the $200,000 using new long-term debt facilities and/or its existing revolving credit facility.  Woodward currently has the ability to utilize its $600,000 revolving credit facility, which matures in July 2018, to refinance the entire $200,000 outstanding balance, if necessary.
	Debt Issuance Costs
	In connection with the Revolving Credit Agreement, Woodward incurred $1,651 in financing costs, which are deferred and will be amortized using the straight-line method over the life of the agreement.  Woodward also had remaining $1,529 of deferred financing costs incurred in connection with the 2012 Credit Facility, which have been combined with the financing costs associated with the Revolving Credit Agreement and are being amortized using the straight-line method over the life of the Revolving Credit Agreement.  The remaining $100 of deferred financing costs incurred in connection with the prior $225,000 revolving credit facility, which was amended and restated by the Third Amended and Restated Credit Agreement in fiscal year 2012, were expensed in the first quarter of fiscal year 2012.
	In connection with the 2013 Note Purchase Agreement, Woodward incurred approximately $1,400 in financing costs, which will be deferred and amortized using the straight-line method over the life of the agreement.  As of September 30, 2013, $200 of financing costs were included in “Other assets” on the Consolidated Balance Sheet.
	Amounts recognized as interest expense from the amortization of debt issuance costs were $1,045 in fiscal year 2013, $1,074 in fiscal year 2012, and $764 in fiscal year 2011.  Woodward had $3,869 of unamortized debt issuance costs as of September 30, 2013 and $3,263 of unamortized debt issuance costs as of September 30, 2012.  Amortization of debt issuance costs is included in operating activities in the Consolidated Statements of Cash Flows.

	Woodward has recorded a net operating loss (“NOL”) deferred tax asset of $7,058 as of September 30, 2013.  A portion of these carryforwards will expire by 2020 and are currently offset by a 100 percent valuation allowance, while the remaining portion has an indefinite carryforward period and has no valuation allowance against it.
	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.
	At September 30, 2013, Woodward has not provided for taxes on undistributed foreign earnings of $207,224 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 subsidies located in the United States, or if Woodward sells its stock in the foreign subsidies.  However, the Company believes that any additional taxes could be offset, in part or in whole, by foreign tax credits.
	The following is a reconciliation of the U.S. Federal statutory tax rate of 35 percent to Woodward’s effective income tax rate:
				Year Ending September 30,
	Percent of pretax earnings			2013			2012			2011
	Statutory tax rate			35.0	%		35.0	%		35.0	%

	Other items, net			-			-0.7			-0.4
	Effective tax rate			26.9	%		28.4	%		29.5	%
	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, we occasionally have 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.
	On January 2, 2013, the American Taxpayer Relief Act of 2012 (the “Taxpayer Relief Act”) was enacted, which retroactively extended the U.S. research and experimentation tax credit through December 31, 2013.  As a result, income taxes for fiscal year 2013 included a net expense reduction related to the retroactive impact from the last three quarters of fiscal year 2012 of the U.S. research and experimentation tax credit pursuant to the Taxpayer Relief Act.
	Income taxes for the year ended September 30, 2012 included a tax benefit of $3,326 related to a reduction in the anticipated amount of undistributed earnings of certain of Woodward’s foreign subsidiaries that were previously expected to be repatriated to the United States within the foreseeable future.  Woodward anticipates that a portion of those earnings will remain indefinitely invested outside the United States and accordingly it reversed the deferred tax liability associated with repatriating those earnings.  This item is included in the “Taxes on international activities” line in the rate reconciliation above.
	A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits follows:
	Balance, September 30, 2010		$	10,586
	Tax positions related to the current year			4,264
	Tax positions related to prior years			3,160
	Lapse of applicable statute of limitations			-1,079
	Balance, September 30, 2011			16,931
Tax positions related to the current year			1,444
Tax positions related to prior years			-169
Lapse of applicable statute of limitations			-137
Balance, September 30, 2012			18,069
Tax positions related to the current year			5,587
Tax positions related to prior years			1,079
Lapse of applicable statute of limitations			-2,041
Balance, September 30, 2013		$	22,694
Included in the balance of unrecognized tax benefits as of September 30, 2013 and September 30, 2012 are $17,838 and $13,713, respectively, of tax benefits that, if recognized, would affect the effective tax rate.  At this time, Woodward estimates that it is reasonably possible that the liability for unrecognized tax benefits will decrease by as much as $565 in the next twelve months due to the completion of reviews by tax authorities and the expiration of certain statutes of limitations.  Woodward accrues for potential interest and penalties related to unrecognized tax benefits in tax expense.  Woodward had accrued interest and penalties of $2,066 as of September 30, 2013 and $1,701 as of September 30, 2012.
Woodward’s tax returns are audited by U.S., state, and foreign tax authorities, and these audits are at various stages of completion at any given time.  With a few exceptions, Woodward’s fiscal years remaining open to examination in the U.S. include fiscal years 2010 and thereafter, and fiscal years remaining open to examination in significant foreign jurisdictions include 2005 and thereafter.

Retirement Benefits	'
	Note 18.  Retirement benefits
	Woodward provides various 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 contributions to eligible employee accounts, which are also deferred for employee personal income tax purposes.  Certain foreign employees are also eligible to participate in foreign plans.
	Most U.S. employees with at least two years 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 quarter of fiscal years 2013 and 2012, Woodward fulfilled the annual Woodward stock contribution using shares held in treasury stock by issuing 250 shares of common stock for a total value of $9,780 and 209 shares of common stock for a total value of $9,335, respectively.  In the second quarter of fiscal year 2011, the annual Woodward stock contribution totaling $9,107 was funded by way of a cash contribution to the Woodward Retirement Savings Plan, which then purchased shares of Woodward stock on the open market.
	The amount of expense associated with defined contribution plans was as follows:
				Year Ended September 30,
			2013			2012			2011
	Company costs		$	20,012		$	18,296		$	16,646
	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 Switzerland.  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 dependants 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.
	In connection with the acquisition of the Duarte Business (see Note 4, Business acquisitions), Woodward did not assume the Seller’s postretirement benefit obligations under the Duarte Business’ defined benefit pension plan as they existed at the time of closing of the transaction.  Under the terms of the Asset Purchase Agreement, Woodward established a new defined benefit pension plan for the Duarte Business employees who were beneficiaries of the Seller’s defined benefit pension plan (the “Duarte Pension Plan”).  Subsequently, Woodward and the Duarte Union agreed that, effective as of the close of business on July 31, 2013, the Duarte Pension Plan was amended to cease all future benefit accruals to current participants in the plan.  In addition, the Duarte Pension Plan was frozen to new entrants as of July 31, 2013.  The Duarte Pension Plan had expenses of $208 and Woodward made $50 of contributions to the plan during of fiscal year 2013.
	In connection with the acquisition of IDS in the third quarter of fiscal year 2011 (see Note 4, Business acquisitions), Woodward assumed pension benefit obligations for the fiscal year ended September 30, 2011.
	In addition to the Duarte Pension Plan, excluding the Woodward HRT Plan, 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:
		2013			2012			2011
	United States:
	Weighted-average assumptions to determine benefit obligation at September 30:
	Discount rate	5.15	%		4.10	%		5.55	%
	Rate of compensation increase	3.50			3.50			4.00
	Weighted-average assumptions to determine periodic benefit costs for years ended September 30:
	Discount rate	4.10			5.55			5.85
	Rate of compensation increase	3.50			4.00			4.00
	Long-term rate of return on plan assets	7.59			7.89			7.90
	United Kingdom:
	Weighted-average assumptions to determine benefit obligation at September 30:
	Discount rate	4.50	%		4.60	%		5.10	%
	Rate of compensation increase	3.50			3.90			4.30
	Weighted-average assumptions to determine periodic benefit costs for years ended September 30:
	Discount rate	4.60			5.10			4.90
	Rate of compensation increase	3.90			4.30			4.30
	Long-term rate of return on plan assets	5.50			6.00			6.00
	Japan:
	Weighted-average assumptions to determine benefit obligation at September 30:
	Discount rate	1.25	%		1.50	%		1.50	%
	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	1.50			1.50			1.25
	Rate of compensation increase	2.00			2.00			2.00
	Long-term rate of return on plan assets	2.80			2.80			3.00
	Switzerland:
	Weighted-average assumptions to determine benefit obligation at September 30:
	Discount rate	2.25	%		1.75	%		2.50	%
	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	1.75			2.50			3.00
	Rate of compensation increase	2.00			2.00			2.00
	Long-term rate of return on plan assets	1.75			2.50			3.00
	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 used a bond portfolio matching analysis based on recently traded, non-callable bonds rated AA or better that have at least $50 million outstanding.    Beginning in fiscal year 2012, Woodward refined its existing estimation process for determining the discount rates in the United Kingdom and Japan and used cash flow matching to develop a single rate equivalent for a theoretical portfolio of non-callable, AA-rated bonds for each jurisdiction.  In fiscal year 2011, Woodward used the iBoxx AA-rated corporate bond index (applicable for bonds over 15 years) to determine a blended rate to use as the benchmark in the United Kingdom, and Woodward used Standard & Poors AA-rated corporate bond yields (applicable for bonds over 10 years) as the benchmark in Japan.    In Switzerland, Woodward used high quality swap rates plus a credit spread of 0.20%, 0.46% and 0.36%, in fiscal years 2013, 2012 and 2011, respectively, as high quality swaps are available in Switzerland at various durations and trade at higher volumes than bonds.  Woodward’s assumed rates do not differ significantly from any of these benchmarks.
	Compensation increase assumptions 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.
	Net periodic benefit costs consist of the following components reflected as expense in Woodward’s Consolidated Statements of Earnings:
			Year Ended September 30,
			United States									Other Countries						Total

Settlement costs were expensed in fiscal years 2013 and 2012 as a result of normal attrition among participants in the Company's defined benefit plan in Switzerland.  Woodward did not have any settlement costs in fiscal year 2011.

Woodward expects its pension plan contributions in fiscal year 2014 will be $500 in the United States, $1,867 in the United Kingdom, $1,108 in Japan and $187 in Switzerland.
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, excluding the pension plan in Switzerland which is a statutory 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 which 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 plan in Japan and the plan in the United Kingdom 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 assets of the plan in Switzerland are insured through an insurance contract that guarantees a federally mandated annual rate of return.  Pension plan assets at September 30, 2013 and 2012 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,
		2013						2012
		Percentage of Plan Assets		Target Allocation Ranges				Percentage of Plan Assets		Target Allocation Ranges
United States:

Total assets		$	129,518		$	149		$	-		$	58,532	$	-	$	1,976	$	190,175
Cash and cash equivalents: Cash and cash equivalents held by the Company's pension plans are held on deposit with creditworthy financial institutions.  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.
Pension assets invested in insurance backed assets:  A reputable Swiss insurer insures the assets of the Company’s Swiss pension plan.  The insurance contract guarantees a federally mandated annual rate of return.  The value of the plan assets is effectively the value of the insurance contract.  The performance of the underlying assets held by the insurance company has no direct impact on the surrender value of the insurance contract.  The insurance backed assets are not traded and therefore have no active market.
Changes in Level 3 pension plan assets consisted of the following:
		For the Year Ended
		30-Sep-13
		Level 3 Assets
Fair value of Level 3 plan assets at beginning of year	$	1,862
Actual return on plan assets		25
Contributions by the Company		205
Contributions by plan participants		214

Foreign currency exchange rate changes		76
Fair value of Level 3 plan assets at end of year	$	1,976
There were no transfers into or out of Level 3 assets in fiscal year 2013.
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 dependants 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 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 the acquisition of HRT 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 900 retired employees and their covered dependants and beneficiaries and may provide future benefits to approximately 60 active employees and their covered dependants and beneficiaries, upon retirement, if the employees elect to participate.  As the result of a plan amendment in fiscal year 2009, 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:
	2013			2012			2011
Weighted-average discount rate used to determine benefit obligation at September 30	5.14	%		4.11	%		5.54	%
Weighted-average discount rate used to determine net periodic benefit cost for years ended September 30	4.11			5.54			5.84
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.    Beginning in fiscal year 2012, Woodward refined its existing estimation process for determining the discount rates in the United Kingdom and used cash flow matching to develop a single rate equivalent for a theoretical portfolio of non-callable, AA-rated bonds.  In fiscal year 2011, Woodward used the iBoxx AA-rated corporate bond index (applicable for bonds over 15 years) to determine a blended rate to use as the benchmark in the United Kingdom.  Woodward’s assumed rate did not differ significantly from this benchmark.
Assumed healthcare cost trend rates at September 30, were as follows:
				2013			2012
Health care cost trend rate assumed for next year				7.00	%		7.50	%
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				2022			2018
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:
		1% increase			1% decrease
Effect on projected fiscal year 2014 service and interest cost		$	141		$	-124
Effect on accumulated postretirement benefit obligation at September 30, 2013			2,620			-2,303
Net periodic benefit costs consist of the following components reflected as expense in Woodward’s Consolidated Statements of Earnings:
		Year Ended September 30,
		2013			2012			2011
Service cost		$	71		$	70		$	92
Interest cost			1,244			1,798			1,974

Net prior service (benefit) cost			-158			-550			-871
Net periodic (benefit) cost		$	1,089		$	1,409		$	1,323

The Company’s postretirement medical plan in the United Kingdom represents $543 of the total benefit obligation at September 30, 2013.  The Company paid $18 in medical benefits to participants of the United Kingdom postretirement medical plan in fiscal year 2013.
The following tables provide the amounts recognized in the statement of financial position and accumulated comprehensive loss (income) for the postretirement plans:
		Year Ended September 30,
		2013			2012
Amounts recognized in statement of financial position consist of:
Accrued liabilities		$	-2,231		$	-2,639
Other non-current liabilities			-26,765			-34,911
Funded status at end of year		$	-28,996		$	-37,550
Amounts recognized in accumulated other comprehensive loss (income) consist of:

Unrecognized net (gains) losses			-4,379			3,053
Total amounts recognized			-5,173			2,102
Deferred taxes			1,970			-794
Amounts recognized in accumulated other comprehensive loss (income)		$	-3,203		$	1,308
Woodward pays plan benefits from its general funds; therefore, there are no segregated plan assets as of September 30, 2013 or September 30, 2012.
The accumulated benefit obligations of the Company’s postretirement plans were $28,996 and $37,550 at September 30, 2013 and 2012, respectively.
Other changes in plan assets and benefit obligations recorded in accumulated other comprehensive income were as follows:
		Year Ended September 30,

Foreign currency exchange rate changes			-			4
Total recorded in accumulated other comprehensive loss (income)		$	-7,275		$	5,875
Using foreign currency exchange rates as of September 30, 2013 and expected future service, it is anticipated that the future Company contributions to pay benefits, excluding participate contributions, will be as follows:
Year Ending September 30,
2014		$	3,954
2015			4,028
2016			4,026
2017			3,956
2018			3,886
2019 – 2023			18,462
Multiemployer defined benefit plans
Woodward operates two multiemployer defined benefit plans for certain employees in the Netherlands and Japan.  The amounts of contributions associated with the multiemployer plans were as follows:
			Year Ended September 30,
		2013			2012			2011
Company contributions		$	797		$	792		$	757
The plan in the Netherlands is a quasi-mandatory plan that covers all of our employees in the Netherlands and is part of the Dutch national pension system.
The Company may elect to withdraw from its multiemployer plan in Japan, although it has no plans to do so. If the Company elects to withdraw from the Japanese plan, it would incur a one-time contribution cost of between $1,500 and $2,000.  Changes in Japanese regulations could trigger reorganization of or abolishment of the Japanese multiemployer plan, which could impact future funding levels.

Stockholders' Equity	'
	Note 19.  Stockholders’ equity
	Common Stock
	Holders of Woodward’s common stock are entitled to receive dividends when and as declared by the Board of Directors and have the right to one vote per share on all matters requiring stockholder approval.
	Dividends declared and paid during the 2013, 2012 and 2011 fiscal years were:
			Year Ended September 30,
			2013			2012			2011
	Dividends declared and paid		$	21,866		$	21,351		$	18,581
	Dividend per share amount			0.32			0.31			0.27
	Stock Repurchase Program
	In July 2010, the Board of Directors authorized the repurchase of up to $200,000 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 July 2013 (the “2010 Authorization”).  Woodward purchased a total of 1,233 shares with an aggregate purchase price of $45,754,  1,132 shares with an aggregate purchase price of $44,110, and 208 shares with an aggregate purchase price of $6,837 of its common stock under the 2010 Authorization in fiscal years 2013, 2012 and 2011, respectively.
	On July 24, 2013, Woodward’s Board of Directors approved a new stock repurchase plan, that replaced the 2010 Authorization, that authorizes the repurchase of up to $200,000 of its outstanding shares of common stock on the open market or in privately negotiated transactions over a three-year period that will end in July 2016 (the “2013 Authorization”).  As of September 30, 2013, Woodward has purchased no shares under the 2013 Authorization.
	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.  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 the outstanding awards are included in the 2006 Omnibus Incentive Plan (the “2006 Plan”) and the 2002 Stock Option Plan (the “2002 Plan”).  The 2006 Plan was approved by stockholders and became effective on January 25, 2006.  No further grants will be made under the 2002 Plan.  The 2006 Plan made 7,410 shares of our common stock available for grants made on or after January 25, 2006, to members and directors of the Company, subject to annual award limits as specified in the 2006 Plan.  In October 2008, Woodward granted 70 shares of restricted stock from treasury stock shares to eligible management employees of MPC pursuant to the 2006 Plan.  These shares became fully vested in fiscal year 2011.  There were 3,120 shares of our common stock available for future grants as of September 30, 2013.
	Stock-based compensation expense recognized was as follows:
		Year Ended September 30,
		2013			2012			2011
	Employee stock-based compensation expense	$	9,414		$	8,628		$	6,590
	Stock options
	The 2006 Plan provides for the grant of up to 7,410 share of our common stock, including in the form of stock options, to its employees and directors.  Woodward believes that these stock options align the interests of its employees and directors with those of its stockholders.  Stock option awards are granted with an exercise price equal to the market price of Woodward’s stock at the date of grant, a  ten-year term, and a four-year vesting schedule at a rate of 25% per year.
	The fair value of options granted was estimated on the date of grant using the Black-Scholes-Merton option-valuation model using the assumptions in the following table.  Woodward calculates the expected term, which represents the 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,

	Woodward also has construction related contractual obligations of approximately $44,000 as of September 30, 2013    related to the development of a second campus in the greater-Rockford, Illinois area, a new campus at its corporate headquarters in Fort Collins, Colorado, and a new facility in Niles, Illinois.
	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, 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 where it believes that it is probable the matter will result in a loss when ultimately resolved using estimates of the most likely amount of loss.
	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 these 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 such officers.

	Note 21.  Segment information
	Woodward serves the aerospace market and the energy market through its two reportable segments - Aerospace and Energy.  Woodward’s reportable segments are aggregations of Woodward’s operating segments.  Woodward uses reportable segment information internally to manage its business, including the assessment of business segment performance and decisions for the allocation of resources between segments.
	The accounting policies of the reportable segments are the same as those of the Company.  Woodward evaluates segment profit or loss based on internal performance measures for each segment in a given period.  In connection with that assessment, Woodward excludes matters such as charges for restructuring costs, interest income and expense, and certain gains and losses from asset dispositions.

Operations_and_summary_of_sign1

Operations and summary of significant accounting policies (Policy)	12 Months Ended
	Sep. 30, 2013
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 doubtful accounts, net realizable value of inventories, cost of sales incentives, 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 vary materially from Woodward’s 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.  Translation adjustments are accumulated with other comprehensive (loss) 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 of the assets and liabilities of its domestic and foreign subsidiaries, are denominated in foreign currencies.  Selling, general, and administrative expenses include net foreign currency losses of $2,738 in fiscal year 2013 and $480 in fiscal year 2012, and gains of $575 in fiscal year 2011.
Revenue recognition	'
	Revenue recognition:  Woodward recognizes revenue upon shipment or delivery of products or services and when collectability is reasonably assured.  Delivery is upon completion of manufacturing, customer acceptance, and the transfer of the risks and rewards of ownership.  In countries whose laws provide for retention of some form of title by sellers, enabling recovery of goods in the event of customer default on payment, product delivery is considered to have occurred when the customer has assumed the risks and rewards of ownership of the products.
	Occasionally, Woodward transfers title of product to customers, but retains substantive performance obligations such as completion of product testing, customer acceptance or in some instances regulatory acceptance.  Revenue is deferred until the performance obligations are satisfied.  In addition, service revenue, which accounts for less than 1% of Woodward’s net sales, is also recognized upon completion of applicable performance obligations.
	Certain Woodward products include incidental software or firmware essential to the performance of the product as designed, which are treated as units of accounting associated with the related tangible product with which the software is included.  Woodward does not sell software on a standalone basis, although software upgrades, if any, are generally paid for by the customer.
	Product freight costs are included in cost of goods sold.  Freight costs charged to customers are included in net sales.
	Taxes collected from customers and remitted to government authorities are excluded from revenue and are recorded as liabilities until the taxes are remitted to the appropriate U.S. or foreign government authority.
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	'
	Research and development costs:  Company funded expenditures related to new product development 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 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”) and sometimes invests excess cash in money market funds not insured by the FDIC.
Accounts receivable	'
	Accounts receivable:  Almost all Woodward’s sales are made on credit and result in accounts receivable, which are recorded at the amount invoiced.  In the normal course of business, not all accounts receivable are collected and, therefore, an allowance for losses of accounts receivable is provided equal to the amount that Woodward believes ultimately will not be collected.  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 in establishing the amount of its allowance.  Accounts receivable 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.
	Consistent with business practice common in China, Woodward’s Chinese subsidiary has accepted in settlement of certain customer accounts receivable from Chinese customers’ bank drafts authorized by large, creditworthy Chinese banks.  These bank drafts represent a promise to pay the balance of the receivable at a future date, albeit under payment terms that can be longer than traditional payment terms.  At September 30, 2013 and September 30, 2012, Woodward had bank drafts of $72,954 and $40,312, respectively, recorded as accounts receivable on its Consolidated Balance Sheets.  Woodward only accepts bank drafts authorized by large, creditworthy banks as to which the credit risk associated with the bank draft is assessed to be minimal.
Inventories	'
	Inventories:  Inventories are valued at the lower of cost or market, with cost being determined using methods that approximate a first-in, first-out basis.
	Customer deposits are recorded against inventory when the right of offset exists.  There were no customer deposits included in inventory as of September 30, 2013 and 2012.  All other customer deposits are recorded in accrued liabilities.
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.  Certain buildings and improvements are depreciated using the declining-balance 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, 2013 were as follows:
	Land improvements	5	-	40	years
	Buildings and improvements	5	-	40	years
	Leasehold improvements	1	-	40	years
	Machinery and production equipment	3	-	15	years
	Computer equipment and software	2	-	10	years
	Office furniture and equipment	2	-	15	years
	Other	1	-	13	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 to five years.
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.
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 would more likely than not reduce the fair value of a reporting unit below its carrying amount.  Based on the relevant U.S. GAAP authoritative guidance, Woodward sometimes 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 including 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.  There was no impairment charge recorded in fiscal years 2013, 2012, or 2011.
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.  All of Woodward’s intangibles have an estimated useful life and are being amortized using patterns that reflect the periods over which the economic benefits of the assets are expected to be realized.  Impairment losses are recognized if the carrying amount of an intangible is both not recoverable and exceeds its fair value.
	Estimated lives over which intangible assets are amortized at September 30, 2013 were as follows:
	Customer relationships	9	-	30	years
	Intellectual property	10	-	17	years
	Process technology	8	-	30	years
	Other	3	-	15	years
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 was no impairment charge recorded in fiscal years 2013, 2012 or 2011.
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 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.
Derivatives	'
	Derivatives:  The Company is exposed to various market risks that arise from transactions entered into in the normal course of business.  The Company has historically 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 balance sheet 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, Woodward will enter into foreign currency exchange rate contracts to hedge against changes in foreign currency exchange rates on liabilities expected to be settled at a future date.  Woodward has historically not designated these transactions as accounting hedges.  The fair value of foreign currency exchange rate contracts held at the end of the period are recognized in the balance sheet and the unrealized gains or losses are recorded to “Other (income) expense, net” in the Consolidated Statements of Earnings.  Upon settlement of foreign currency exchange rate contracts, any unrealized gains or losses previously recognized are reversed and the realized gain or loss is recorded to “Other (income) expense, net” in the Consolidated Statement of Earnings.  Further information on foreign currency exchange rate contracts can be found at Note 6, Derivative instruments and hedging activities.
Financial Instruments	'
	Financial instruments:  The Company’s financial instruments include cash and cash equivalents, investments in the deferred compensation program 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 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 5, 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.  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.  Accumulated benefit obligation differs from projected benefit obligation in that it includes no assumption about future compensation levels.
Deferred Compensation, Excluding Share-based Payments and Retirement Benefits [Member]	'
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 Sheet 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.”

Line of Credit Facility, Rationale for Classification as Long-term Debt

'

'

'

'

'

'

'

'Woodward classified the $200,000 outstanding on the Line of Credit as long-term as of September 30, 2013 based on its intention to refinance the $200,000 using new long-term debt facilities and/or its existing revolving credit facility. Woodward currently has the ability to utilize its $600,000 revolving credit facility, which matures in July 2018, to refinance the entire $200,000 outstanding balance, if necessary.

'Woodward classified the $200,000 outstanding on the Line of Credit as long-term as of September 30, 2013 based on its intention to refinance the $200,000 using new long-term debt facilities and/or its existing revolving credit facility. Woodward currently has the ability to utilize its $600,000 revolving credit facility, which matures in July 2018, to refinance the entire $200,000 outstanding balance, if necessary.
