Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Consolidation: The consolidated financial statements include the accounts of Moog Inc. and all of our U.S. and foreign subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Fiscal Year: Our fiscal year ends on the Saturday that is closest to September 30. The consolidated financial statements include 53 weeks for the year ended October 3, 2015 and 52 weeks for the years ended September 27, 2014 and September 28, 2013 . Operating Cycle: Consistent with industry practice, aerospace and defense related inventories, unbilled recoverable costs and profits on long-term contract receivables, customer advances and contract loss reserves include amounts relating to contracts having long production and procurement cycles, portions of which are not expected to be realized or settled within one year. Foreign Currency Translation: Assets and liabilities of subsidiaries that prepare financial statements in currencies other than the U.S. dollar are translated using rates of exchange as of the balance sheet date and the statements of earnings are translated at the average rates of exchange for each reporting period. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and assumptions. Revenue Recognition: We recognize revenue using either the percentage of completion method for contracts or as units are delivered or services are performed. Percentage of completion method for contracts : Revenue representing 33% , 34% and 33% of 2015 , 2014 and 2013 sales, respectively, was accounted for using the percentage of completion, cost-to-cost method of accounting. This method of revenue recognition is predominantly used within the Aircraft Controls and Space and Defense Controls segments due to the contractual nature of the business activities, with the exception of their respective aftermarket activities. The contractual arrangements are either firm fixed-price or cost-plus contracts and are primarily with the U.S. Government or its prime subcontractors, foreign governments or commercial aircraft manufacturers, including Boeing and Airbus. The nature of the contractual arrangements includes customers’ requirements for delivery of hardware as well as funded nonrecurring development work in anticipation of follow-on production orders. Revenue on contracts using the percentage of completion, cost-to-cost method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total estimated contract revenue, less cumulative revenue recognized in prior periods. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for substantially all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations. Occasionally, it is appropriate to combine or segment contracts. Contracts are combined in those limited circumstances when they are negotiated as a package in the same economic environment with an overall profit margin objective and constitute, in essence, an agreement to do a single project. In such cases, revenue and costs are recognized over the performance period of the combined contracts as if they were one. Contracts are segmented in limited circumstances if the customer had the right to accept separate elements of the contract and the total amount of the proposals on the separate components approximated the amount of the proposal on the entire project. For segmented contracts, revenue and costs are recognized as if they were separate contracts over the performance periods of the individual elements or phases. Contract costs include only allocable, allowable and reasonable costs, as determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards for applicable U.S. Government contracts, and are included in cost of sales when incurred. The nature of these costs includes development engineering costs and product manufacturing costs including direct material, direct labor, other direct costs and indirect overhead costs. Contract profit is recorded as a result of the revenue recognized less costs incurred in any reporting period. Amounts representing performance incentives, penalties, contract claims or change orders are considered in estimating revenues, costs and profits when they can be reliably estimated and realization is considered probable. Revenue recognized on contracts for unresolved claims or unapproved contract change orders was not material for 2015 , 2014 or 2013 . For contracts with anticipated losses at completion, a provision for the entire amount of the estimated remaining loss is charged against income in the period in which the loss becomes known. Contract losses are determined considering all direct and indirect contract costs, exclusive of any selling, general or administrative cost allocations that are treated as period expenses. Loss reserves are more common on firm fixed-price contracts that involve, to varying degrees, the design and development of new and unique controls or control systems to meet the customers’ specifications. As units are delivered or services are performed : In 2015 , 67% of our sales were recognized as units were delivered or as service obligations were satisfied. Revenue is recognized when the risks and rewards of ownership and title to the product are transferred to the customer. When engineering or similar services are performed, revenue is recognized upon completion of the obligation including any delivery of engineering drawings or technical data. This method of revenue recognition is predominantly used within the Industrial Systems, Components and Medical Devices segments, as well as with aftermarket activity. Profits are recorded as costs are relieved from inventory and charged to cost of sales and as revenue is recognized. Inventory costs include all product manufacturing costs such as direct material, direct labor, other direct costs and indirect overhead cost allocations. Shipping and Handling Costs: Shipping and handling costs are included in cost of sales. Research and Development: Research and development costs are expensed as incurred and include salaries, benefits, consulting, material costs and depreciation. Bid and Proposal Costs: Bid and proposal costs are expensed as incurred and classified as selling, general and administrative expenses. Equity-Based Compensation: Equity-based compensation expense is included in selling, general and administrative expenses. Earnings Per Share: Basic and diluted weighted-average shares outstanding are as follows: 2015 2014 2013 Basic weighted-average shares outstanding 38,945,880 44,362,412 45,335,336 Dilutive effect of equity-based awards 388,640 590,025 488,384 Diluted weighted-average shares outstanding 39,334,520 44,952,437 45,823,720 Cash and Cash Equivalents: All highly liquid investments with an original maturity of three months or less are considered cash equivalents. Allowance for Doubtful Accounts: The allowance for doubtful accounts is based on our assessment of the collectibility of customer accounts. The allowance is determined by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. Inventories: Inventories are stated at the lower-of-cost-or-market with cost determined on the first-in, first-out (FIFO) method of valuation. Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated principally using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 15 years for building improvements, 12 years for furniture and fixtures, 10 years for machinery and equipment, 8 years for tooling and test equipment and 3 to 5 years for computer hardware and software. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the asset, whichever is shorter. Goodwill: We test goodwill for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that indicate that the fair value of a reporting unit is likely to be below its carrying amount. We also test goodwill for impairment when there is a change in reporting units. We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or selected reporting units. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test instead of a qualitative test for any or all of our reporting units. Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. We use the discounted cash flow method to estimate the fair value of our reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating margins and cash flows, the terminal growth rate and the weighted-average cost of capital. If the carrying value of the reporting unit exceeds its fair value, goodwill is considered impaired and any loss must be measured. To determine the amount of the impairment loss, the implied fair value of goodwill is determined by assigning a fair value to all of the reporting unit's assets and liabilities, including any unrecognized intangible assets, as if the reporting unit had been acquired in a business combination at fair value. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss would be recognized in an amount equal to that excess. We recorded a $38,200 goodwill impairment charge in 2013 in our Medical Devices reporting unit. There were no impairment charges recorded in 2015 or 2014 . Acquired Intangible Assets: Acquired identifiable intangible assets are recorded at cost and are amortized over their estimated useful lives. Impairment of Long-Lived Assets: Long-lived assets, including acquired identifiable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. We use undiscounted cash flows to determine whether impairment exists and measure any impairment loss using discounted cash flows. In 2014, we recorded a $739 impairment charge in our Industrial Systems segment related to intangible assets from a product line we decided to exit. We also recorded a $1,296 impairment charge in our Medical Devices segment related to equipment from a product line we are no longer pursuing. Both of these charges are included as restructuring in the consolidated statements of earnings. In 2015, we recorded impairment charges of $2,432 in our Industrial Systems segment, primarily related to intangible assets from a wind energy product line that we decided to exit, which is included as other expense. We also recorded an additional $472 impairment charge related to intangible assets on the product line we decided to exit in 2014, which is included as restructuring in the consolidated statement of earnings. There were no impairment charges recorded in 2013 . Product Warranties: In the ordinary course of business, we warrant our products against defect in design, materials and workmanship typically over periods ranging from twelve to sixty months. We determine warranty reserves needed by product line based on historical experience and current facts and circumstances. Activity in the warranty accrual is summarized as follows: 2015 2014 2013 Warranty accrual at beginning of year $ 19,953 $ 17,429 $ 18,859 Warranties issued during current year 9,666 12,611 9,019 Adjustments to pre-existing warranties (2,416 ) (2,037 ) (1,911 ) Reductions for settling warranties (7,448 ) (7,759 ) (8,507 ) Foreign currency translation (1,095 ) (291 ) (31 ) Warranty accrual at end of year $ 18,660 $ 19,953 $ 17,429 Financial Instruments: Our financial instruments consist primarily of cash and cash equivalents, receivables, notes payable, accounts payable, long-term debt, interest rate swaps and foreign currency forwards. The carrying values for our financial instruments approximate fair value with the exception at times of long-term debt. We do not hold or issue financial instruments for trading purposes. We carry derivative instruments on the consolidated balance sheets at fair value, determined by reference to quoted market prices. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. Our use of derivative instruments is generally limited to cash flow hedges of certain interest rate risks and minimizing foreign currency exposure on foreign currency transactions, which are typically designated in hedging relationships, and intercompany balances, which are not designated as hedging instruments. Cash flows resulting from forward contracts are accounted for as hedges of identifiable transactions or events and classified in the same category as the cash flows from the items being hedged. Recent Accounting Pronouncements : In March 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Group of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU is intended to eliminate diversity in practice on the release of cumulative translation adjustments into net income when a parent either sells part or all of its investment in a foreign entity, or when it no longer holds a controlling financial interest. In addition, the amendments resolve the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The provisions of this ASU are effective for fiscal years beginning after December 15, 2013 and interim periods within those fiscal years. We adopted this amendment in the first quarter of 2015. The adoption of this standard did not have a material impact on our financial statements. In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase to Maturity Transactions, Repurchase Financings and Disclosures.” This ASU changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting, requires certain disclosures for transactions accounted for as sales and requires certain disclosures for other transactions accounted for as secured borrowings. The provisions of this ASU are effective for fiscal years beginning after December 15, 2014 and for interim periods beginning after March 15, 2015. We adopted this amendment in the third quarter of 2015. The adoption of this standard did not have a material impact on our financial statements. In April 2015, the FASB issued ASU No. 2015-04, “Compensation - Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets.” This ASU permits an entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that consistently from year to year. This practical expedient would then be applied to all plans if an entity has more than one plan. Further, if a contribution or other significant event occurs between the month-end date used to measure defined benefit plan assets and obligations and an entity’s fiscal year-end, the entity should adjust the measurement of the defined benefit plan assets and obligations to reflect the effects of those contributions and other significant events. The provisions of this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted, and prospective application is required. We adopted this standard in 2015, and changed our method of measuring plan assets and obligations related to our defined benefit plans. This change simplifies our reporting while maintaining the usefulness of information presented in our financial statements. The adoption of this standard did not have a material impact on our financial statements.

Business Combinations [Abstract]
Acquisitions	Acquisitions and Divestitures In 2015, we completed a divestiture in our Medical Devices segment. We sold our Rochester, New York and Erie, Pennsylvania life sciences operations for $2,988 in cash. In 2013, we completed a divestiture in our Medical Devices segment. We sold our Buffalo, New York operations of Ethox Medical for $5,000 in cash, plus a $200 note receivable. In 2013, we also completed business combinations. One of these business combinations was in our Space and Defense Controls segment. We acquired Broad Reach Engineering for $34,550 of cash consideration, issuance of $8,450 of notes payable and contingent consideration with an initial fair value of $3,447 . Based in Colorado, Broad Reach Engineering is a leading designer and manufacturer of spaceflight electronics and software for aerospace, scientific, commercial and military missions. The company also provides ground testing, launch and on-orbit operations. We also completed one business combination in our Components segment. We acquired Aspen Motion Technologies, located in Radford, Virginia for $33,911 in cash. Aspen is a designer and manufacturer of high-performance permanent magnet brushless DC motors, integrated digital controls and motorized impellers. Aspen also specializes in custom motor designs for end product integration and significant product enhancement in a variety of high-performance industrial applications. The purchase price allocations for the 2013 acquisitions are complete. All of our acquisitions are accounted for under the purchase method and, accordingly, the operating results for the acquired companies are included in the consolidated statements of earnings from the respective dates of acquisition. Under purchase accounting, we record assets and liabilities at fair value and such amounts are reflected in the respective captions on the consolidated balance sheets.

We maintain a subordinated interest in a portion of the pool of trade receivables that are securitized. The retained interest, which is included in receivables in the consolidated balance sheets, is recorded at fair value, which approximates the total amount of the designated pool of accounts receivable. See Note 7, Indebtedness, for additional disclosures related to the Securitization Program. Long-term contract receivables are primarily associated with prime contractors and subcontractors in connection with U.S. Government contracts, commercial aircraft and satellite manufacturers. Amounts billed under long-term contracts to the U.S. Government were $8,284 at October 3, 2015 and $16,929 at September 27, 2014 . Unbilled recoverable costs and accrued profits under long-term contracts to be billed to the U.S. Government were $13,733 at October 3, 2015 and $15,816 at September 27, 2014 . Unbilled recoverable costs and accrued profits principally represent revenues recognized on contracts that were not billable on the balance sheet date. These amounts will be billed in accordance with contract terms, generally as certain milestones are reached or upon shipment. Approximately 75% of unbilled amounts are expected to be collected within one year. In situations where billings exceed revenues recognized, the excess is included in customer advances. There are no material amounts of claims or unapproved change orders included in the consolidated balance sheets. There are no material balances billed but not paid by customers under retainage provisions. Concentrations of credit risk on receivables are limited to those from significant customers who are believed to be financially sound. Receivables from Boeing were $161,820 at October 3, 2015 and $147,421 at September 27, 2014 . We perform periodic credit evaluations of our customers’ financial condition and generally do not require collateral.

We test goodwill for impairment at least annually, during our fourth quarter. We estimated the fair value of this reporting unit using a discounted cash flow analysis, and our result was supported by information obtained as part of our strategic review of this business. In the fourth quarter of 2013, we began a strategic assessment of our Medical Devices segment. We determined that the medical pumps business is not core to our overall strategy, but we are currently operating the business as part of ongoing operations. See Note 17, Segments, for additional disclosures related to the change in segment classification.

Customer-related intangible assets primarily consist of customer relationships. Program-related intangible assets consist of long-term programs represented by current contracts and probable follow on work. Technology-related intangible assets primarily consist of technology, patents, intellectual property and software. Marketing-related intangible assets primarily consist of trademarks, trade names and non-compete agreements. Amortization of acquired intangible assets was $24,708 in 2015 , $29,907 in 2014 and $31,137 in 2013 . Based on acquired intangible assets recorded at October 3, 2015 , amortization is estimated to be approximately $21,900 in 2016 , $18,500 in 2017 , $17,100 in 2018 , $15,900 in 2019 and $14,500 in 2020 .

The amendment increased the capacity on our revolving credit facility from $900,000 to $1,100,000 and extended the maturity of the credit facility to May 22, 2019 . The amendment also provides an expansion option, which permits us to request an increase to the credit facility of up to $200,000 upon satisfaction of certain conditions. The credit facility is secured by substantially all of our U.S. assets. The loan agreement contains various covenants which, among others, specify interest coverage and maximum leverage and capital expenditures. We are in compliance with all covenants. Interest on all of the outstanding credit facility borrowings is 1.8% and is based on LIBOR plus the applicable margin, which was 163 basis points at October 3, 2015 . On November 21, 2014 , we completed the sale of $300,000 aggregate principal amount of 5.25% senior notes due December 1, 2022 at par with interest paid semiannually on June 1 and December 1 of each year, which commenced on June 1, 2015 . The senior notes are unsecured obligations, guaranteed on a senior unsecured basis by certain subsidiaries and contain normal incurrence-based covenants and limitations such as the ability to incur additional indebtedness, pay dividends, make other restricted payments and investments, create liens and certain corporate acts such as mergers and consolidations. The aggregate net proceeds of $294,430 were used to repay indebtedness under our U.S. bank credit facility, thereby increasing the unused portion of our revolving credit facility. The Securitization Program was extended on February 10, 2015 and now matures on February 10, 2017 and effectively increases our borrowing capacity by up to $100,000 . Under the Securitization Program, we sell certain trade receivables and related rights to an affiliate, which in turn sells an undivided variable percentage ownership interest in the trade receivables to a financial institution, while maintaining a subordinated interest in a portion of the pool of trade receivables. Interest for the Securitization Program is 0.9% at October 3, 2015 and is based on 30-day LIBOR plus an applicable margin. A commitment fee is also charged based on a percentage of the unused amounts available and is not material . The agreement governing the Securitization Program contains restrictions and covenants which include limitations on the making of certain restricted payments, creation of certain liens, and certain corporate acts such as mergers, consolidations and sale of substantially all assets. The Securitization Program has a minimum borrowing requirement equal to the lesser of either 80% of our borrowing capacity or 100% of our borrowing base, which is a subset of the trade receivables sold under this agreement. As of October 3, 2015 , our minimum borrowing requirement is $80,000 . On December 19, 2013 , we repurchased our 7.25% senior subordinated notes due on January 15, 2018 at 103.625% , pursuant to an early redemption right. We redeemed the aggregate principal amount of $200,000 using proceeds drawn from our U.S. revolving credit facility. The associated loss on the redemption includes $6,945 of call premium paid to external bondholders and a $1,057 write off of deferred debt issuance costs. Maturities of long-term debt are $34 in 2016 , $100,033 in 2017 , $24 in 2018 , $675,010 in 2019 , $0 in 2020 and $300,000 thereafter. At October 3, 2015 , we had pledged assets with a net book value of $1,508,996 as security for long-term debt. At October 3, 2015 , we had $420,193 of unused short and long-term borrowing capacity, including $408,227 from the U.S. revolving credit facility. Commitment fees are charged on some of these arrangements and on the U.S. revolving credit facility based on a percentage of the unused amounts available and are not material .

Derivative Instruments and Hedges, Assets [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We principally use derivative financial instruments to manage interest rate risk associated with long-term debt and foreign exchange risk related to foreign operations and foreign currency transactions. We enter into derivative financial instruments with a number of major financial institutions to minimize counterparty credit risk. Derivatives designated as hedging instruments Interest rate swaps are used to adjust the proportion of total debt that is subject to variable and fixed interest rates. The interest rate swaps are designated as hedges of the amount of future cash flows related to interest payments on variable-rate debt that, in combination with the interest payments on the debt, convert a portion of the variable-rate debt to fixed-rate debt. At October 3, 2015 , we had interest rate swaps with notional amounts totaling $245,000 . The interest rate swaps effectively convert this amount of variable-rate debt to fixed-rate debt at 2.3% , including the applicable margin of 163 basis points as of October 3, 2015 . The interest will revert back to variable rates based on LIBOR plus the applicable margin upon the maturity of the interest rate swaps. These interest rate swaps mature at various times between January 15, 2016 and June 5, 2017 . We use foreign currency forward contracts as cash flow hedges to effectively fix the exchange rates on future payments and revenue. To mitigate exposure in movements between various currencies, primarily the Philippine peso, we had outstanding foreign currency forwards with notional amounts of $53,659 at October 3, 2015 . These contracts mature at various times through September 1, 2017 . These interest rate swaps and foreign currency forwards are recorded on the consolidated balance sheet at fair value and the related gains or losses are deferred in shareholders’ equity as a component of Accumulated Other Comprehensive Income (Loss) (AOCI). These deferred gains and losses are reclassified into expense during the periods in which the related payments or receipts affect earnings. However, to the extent the interest rate swaps and foreign currency forwards are not perfectly effective in offsetting the change in the value of the payments being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was not material in 2015 , 2014 or 2013 . Derivatives not designated as hedging instruments We also have foreign currency exposure on balances, primarily intercompany, that are denominated in a foreign currency and are adjusted to current values using period-end exchange rates. The resulting gains or losses are recorded in the consolidated statements of earnings. To minimize foreign currency exposure, we have foreign currency forwards with notional amounts of $108,391 at October 3, 2015 . The foreign currency forwards are recorded in the consolidated balance sheets at fair value and resulting gains or losses are recorded in the consolidated statements of earnings. We recorded a net loss of $1,344 in 2015 and a net gain of $4,105 in 2014 on the foreign currency forwards. These gains and losses are included in other expense and generally offset the gains and losses from the foreign currency adjustments on the intercompany balances that are also included in other income or expense. Summary of derivatives The fair value and classification of derivatives is summarized as follows: October 3, 2015 September 27, 2014 Derivatives designated as hedging instruments: Foreign currency forwards Other current assets $ 12 $ — Foreign currency forwards Other assets 39 — Interest rate swaps Other current assets — 70 Interest rate swaps Other assets — 107 Total asset derivatives $ 51 $ 177 Foreign currency forwards Other accrued liabilities $ 1,755 $ 1,521 Foreign currency forwards Other long-term liabilities 572 494 Interest rate swaps Other accrued liabilities 756 110 Interest rate swaps Other long-term liabilities 268 28 Total liability derivatives $ 3,351 $ 2,153 Derivatives not designated as hedging instruments: Foreign currency forwards Other current assets $ 115 $ 821 Foreign currency forwards Other accrued liabilities $ 429 $ 2,991

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. The definition of the fair value hierarchy is as follows: Level 1 – Quoted prices in active markets for identical assets and liabilities. Level 2 – Observable inputs other than quoted prices in active markets for similar assets and liabilities. Level 3 – Inputs for which significant valuation assumptions are unobservable in a market and therefore value is based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require. Our derivatives are valued using various pricing models or discounted cash flow analyses that incorporate observable market data, such as interest rate yield curves and currency rates, and are classified as Level 2 within the valuation hierarchy. Our Level 3 fair value liabilities represent contingent consideration recorded for acquisitions to be paid if various financial targets are met. The amounts recorded were calculated for each payment scenario in each period using an estimate of the probability of the future cash outflows. The varying contingent payments were then discounted to the present value at the weighted average cost of capital. Fair value is assessed on a quarterly basis, or whenever events or circumstances change that indicate an adjustment is required. The assessment includes an evaluation of the performance of the acquired business compared to previous expectations, changes to future projections and the probability of achieving the earn out targets. The following table presents the fair values and classification of our financial assets and liabilities measured on a recurring basis, all of which are classified as Level 2: Classification October 3, 2015 September 27, 2014 Foreign currency forwards Other current assets $ 127 $ 821 Foreign currency forwards Other assets 39 — Interest rate swaps Other current assets — 70 Interest rate swaps Other assets — 107 Total assets $ 166 $ 998 Foreign currency forwards Other accrued liabilities $ 2,184 $ 4,512 Foreign currency forwards Other long-term liabilities 572 494 Interest rate swaps Other accrued liabilities 756 110 Interest rate swaps Other long-term liabilities 268 28 Total liabilities $ 3,780 $ 5,144 There were no financial assets or liabilities classified as Level 3 within the fair value hierarchy for the year ended October 3, 2015 . The changes in financial liabilities classified as Level 3 within the fair value hierarchy are as follows: 2014 Balance at beginning of year $ 4,007 Decrease in discounted future cash flows recorded as interest expense (121 ) Decrease in earn out provisions recorded as other income (1,585 ) Settlements paid in cash (2,301 ) Balance at end of year $ — Our only financial instrument for which the carrying value differs from its fair value is long-term debt. At October 3, 2015, the fair value of long-term debt was $1,072,101 compared to its carrying value of $1,075,101 . The fair value of long-term debt is classified as Level 2 within the fair value hierarchy and was estimated based on quoted market prices.

Restructuring Charges [Abstract]
Restructuring	Restructuring In 2015, we initiated additional restructuring plans as a result of ongoing reviews of our lines of business and operations. The restructuring actions taken have resulted in workforce reductions, primarily in the U.S., Europe and Asia. In 2014, we initiated restructuring plans in response to the business outlook, which includes a change in the mix of sales and delays and cancellations of orders for certain product lines. The restructuring actions taken have resulted in workforce reductions, primarily in the U.S. and Europe. In 2013, we initiated restructuring plans to better align our cost structure with projected sales levels. The restructuring actions taken have resulted in workforce reductions, primarily in the U.S., Europe and Asia. The restructuring charge in 2015 principally relates to severance, but also includes $3,773 related to the termination of a sales and marketing contract and $472 for the impairment of intangible assets in our Industrial Systems segment. Restructuring expense in 2014 principally relates to severance, but also includes $1,296 for the impairment of long-lived assets in our Medical Devices segment and $739 for the impairment of intangibles assets in our Industrial Systems segment.

Our qualified U.S. defined benefit pension plan is not open to new entrants. New employees are not eligible to participate in the pension plan. Instead, we make contributions for those employees to an employee-directed investment fund in the Moog Inc. Retirement Savings Plan ("RSP"). The Company’s contributions are based on a percentage of the employee’s eligible compensation and age. These contributions are in addition to the employer match on voluntary employee contributions. The RSP includes an Employee Stock Ownership Plan. As one of the investment alternatives, participants in the RSP can acquire our stock at market value. We match 25% of the first 2% of eligible compensation contributed to any investment selection. Shares are allocated and compensation expense is recognized as the employer share match is earned. At October 3, 2015 , the participants in the RSP owned 459,928 Class A shares and 1,465,324 Class B shares. The changes in projected benefit obligations and plan assets and the funded status of the U.S. and non-U.S. defined benefit plans are as follows: U.S. Plans Non-U.S. Plans 2015 2014 2015 2014 Change in projected benefit obligation: Projected benefit obligation at prior year measurement date $ 784,203 $ 678,063 $ 188,942 $ 169,980 Service cost 23,635 21,571 6,087 5,533 Interest cost 34,031 33,354 4,814 5,984 Contributions by plan participants — — 774 1,014 Actuarial losses 35,064 74,369 4,639 22,702 Foreign currency exchange impact — — (19,149 ) (10,237 ) Benefits paid from plan assets (22,612 ) (20,032 ) (2,186 ) (2,697 ) Benefits paid by Moog (2,508 ) (1,883 ) (2,312 ) (2,985 ) Other (822 ) (1,239 ) (1,498 ) (352 ) Projected benefit obligation at measurement date $ 850,991 $ 784,203 $ 180,111 $ 188,942 Change in plan assets: Fair value of assets at prior year measurement date $ 585,677 $ 498,918 $ 120,754 $ 98,625 Actual return on plan assets (28,435 ) 50,630 4,437 11,631 Employer contributions 47,666 59,283 8,208 20,655 Contributions by plan participants — — 774 1,014 Benefits paid (25,120 ) (21,915 ) (4,498 ) (5,682 ) Foreign currency exchange impact — — (10,983 ) (5,425 ) Other (1,005 ) (1,239 ) (999 ) (64 ) Fair value of assets at measurement date $ 578,783 $ 585,677 $ 117,693 $ 120,754 Funded status and amount recognized in assets and liabilities $ (272,208 ) $ (198,526 ) $ (62,418 ) $ (68,188 ) Amount recognized in assets and liabilities: Other assets - non-current $ — $ — $ 220 $ 4,191 Accrued and long-term pension liabilities (272,208 ) (198,526 ) (62,638 ) (72,379 ) Amount recognized in assets and liabilities $ (272,208 ) $ (198,526 ) $ (62,418 ) $ (68,188 ) Amount recognized in accumulated other comprehensive loss, before taxes: Prior service cost (credit) $ 881 $ 846 $ (737 ) $ (363 ) Actuarial losses 386,759 298,534 38,869 40,254 Amount recognized in accumulated other comprehensive loss, before taxes $ 387,640 $ 299,380 $ 38,132 $ 39,891 Our stock included in U.S. plan assets consisted of 149,022 shares of Class A common stock and 1,001,034 shares of Class B common stock. Our funding policy is to contribute at least the amount required by law in the respective countries. The total accumulated benefit obligation as of the measurement date for all defined benefit pension plans was $941,266 in 2015 and $877,846 in 2014 . At the measurement date in 2015 , our plans had fair values of plan assets totaling $696,476 . At the measurement date in 2015 , three of our plans had fair values of plan assets totaling $62,070 , which exceeded their accumulated benefit obligations of $54,603 . At the measurement date in 2014 , three of our plans had fair values of plan assets totaling $78,643 , which exceeded their accumulated benefit obligations of $67,423 . The following table provides aggregate information for the other pension plans, which have projected benefit obligations or accumulated benefit obligations in excess of plan assets: October 3, 2015 September 27, 2014 Projected benefit obligation $ 968,848 $ 895,302 Accumulated benefit obligation 886,663 810,424 Fair value of plan assets 634,406 627,788 Weighted-average assumptions used to determine benefit obligations as of the measurement dates and weighted-average assumptions used to determine net periodic benefit cost are as follows: U.S. Plans Non-U.S. Plans 2015 2014 2013 2015 2014 2013 Assumptions for net periodic benefit cost: Discount rate 4.4 % 5.0 % 3.7 % 3.1 % 3.7 % 4.0 % Return on assets 8.0 % 8.4 % 8.6 % 4.5 % 4.1 % 4.5 % Rate of compensation increase 4.1 % 4.1 % 4.1 % 3.0 % 2.8 % 2.9 % Assumptions for benefit obligations: Discount rate 4.5 % 4.4 % 5.0 % 3.0 % 3.1 % 3.6 % Rate of compensation increase 4.1 % 4.1 % 4.1 % 3.0 % 2.7 % 2.8 % Pension plan investment policies and strategies are developed on a plan specific basis, which varies by country. The overall objective for the long-term expected return on both domestic and international plan assets is to earn a rate of return over time to meet anticipated benefit payments in accordance with plan provisions. The long-term investment objective of both the domestic and international retirement plans is to maintain the economic value of plan assets and future contributions by producing positive rates of investment return after subtracting inflation, benefit payments and expenses. Each of the plan’s strategic asset allocations is based on this long-term perspective and short-term fluctuations are viewed with appropriate perspective. The U.S. qualified defined benefit plan’s assets are invested for long-term investment results. To accommodate the long-term investment horizon while providing appropriate liquidity, the plan maintains a liquid cash reserve of one-month to three-months of benefit distributions. Its assets are broadly diversified to help alleviate the risk of adverse returns in any one security or investment class. The international plans’ assets are invested in both low-risk and high-risk investments in order to achieve the long-term investment strategy objective. Investment risks for both domestic and international plans are considered within the context of the entire plan, rather than on a security-by-security basis. The U.S. qualified defined benefit plan and certain international plans have investment committees that are responsible for formulating investment policies, developing manager guidelines and objectives and approving and managing qualified advisors and investment managers. The guidelines established for each of the plans define permitted investments within each asset class and apply certain restrictions such as limits on concentrated holdings in order to meet overall investment objectives. Pension obligations and the related costs are determined using actuarial valuations that involve several assumptions. The return on assets assumption reflects the average rate of return expected on funds invested or to be invested to provide for the benefits included in the projected benefit obligation. In determining the return on assets assumption, we consider the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes and economic and other indicators of future performance. Asset management objectives include maintaining an adequate level of diversification to reduce interest rate and market risk and to provide adequate liquidity to meet immediate and future benefit payment requirements. In determining our U.S. pension expense for 2015 , we assumed an average rate of return on U.S. pension assets of approximately 8.0% measured over a planning horizon with reasonable and acceptable levels of risk. The rate of return assumed an average of 60% in equity securities, 30% in fixed income securities and 10% in other securities. In determining our non-U.S. pension expense for 2015 , we assumed an average rate of return on non-U.S. pension assets of approximately 4.5% measured over a planning horizon with reasonable and acceptable levels of risk. The rate of return assumed an average asset allocation of 40% in equity securities and 60% in fixed income securities. The weighted average asset allocations by asset category for the pension plans as of October 3, 2015 and September 27, 2014 are as follows: U.S. Plans Non-U.S. Plans Target 2015 2014 Target 2015 2014 Asset category: Equity 45%-70% 59% 54% 30%-50% 30% 30% Debt 20%-35% 31% 34% 40%-60% 42% 42% Real estate and other 10%-20% 10% 12% 10%-30% 28% 28% The following tables present the consolidated plan assets using the fair value hierarchy, which is described in Note 9 - Fair Value, as of October 3, 2015 and September 27, 2014 . U.S. Plans, October 3, 2015 Level 1 Level 2 Level 3 Total Shares of registered investment companies: Non-investment grade $ — $ 38,517 $ — $ 38,517 Real assets — 35,647 — 35,647 Other — 78,102 — 78,102 Fixed income funds: U.S. Government obligations — 64,441 — 64,441 Corporate and other — 106,120 — 106,120 Employer securities 62,214 — — 62,214 Interest in common collective trusts — 88,870 — 88,870 Money market funds — 16,887 — 16,887 Limited partnerships — — 64,760 64,760 Insurance contracts and other — — 23,225 23,225 Fair value $ 62,214 $ 428,584 $ 87,985 $ 578,783 Non-U.S. Plans, October 3, 2015 Level 1 Level 2 Level 3 Total Shares of registered investment companies $ — $ 30,294 $ — $ 30,294 Domestic equity 6,142 209 — 6,351 International equity 8,806 — — 8,806 Fixed income funds 5,615 35,780 — 41,395 Cash and cash equivalents 252 880 — 1,132 Insurance contracts and other — 779 28,936 29,715 Fair value $ 20,815 $ 67,942 $ 28,936 $ 117,693 U.S. Plans, September 27, 2014 Level 1 Level 2 Level 3 Total Shares of registered investment companies: Non-investment grade $ 66,201 $ — $ — $ 66,201 Other 7,442 — — 7,442 Fixed income funds: U.S. Government obligations — 47,275 — 47,275 Corporate and other — 82,850 — 82,850 Employer securities 78,874 — — 78,874 Interest in common collective trusts — 153,183 — 153,183 Money market funds — 46,135 — 46,135 Limited partnerships — — 81,342 81,342 Insurance contracts and other — — 22,375 22,375 Fair value $ 152,517 $ 329,443 $ 103,717 $ 585,677 Non-U.S. Plans, September 27, 2014 Level 1 Level 2 Level 3 Total Shares of registered investment companies $ — $ 32,819 $ — $ 32,819 Domestic equity 6,731 195 — 6,926 International equity 8,730 — — 8,730 Fixed income funds 4,976 35,774 — 40,750 Cash and cash equivalents 85 497 — 582 Insurance contracts and other — 764 30,183 30,947 Fair value $ 20,522 $ 70,049 $ 30,183 $ 120,754 The following is a roll forward of the consolidated plan assets classified as Level 3 within the fair value hierarchy: U.S. Plans Non-U.S. Plans Total Balance at September 28, 2013 $ 92,267 $ 25,820 $ 118,087 Return on assets 8,852 4,689 13,541 Purchases from contributions to Plans 14,426 2,086 16,512 Proceeds from sales of investments (3,511 ) — (3,511 ) Settlements paid in cash (8,317 ) (250 ) (8,567 ) Foreign currency translation — (2,162 ) (2,162 ) Balance at September 27, 2014 103,717 30,183 133,900 Return on assets 849 1,083 1,932 Purchases from contributions to Plans 39,188 3,118 42,306 Proceeds from sales of investments (54,479 ) — (54,479 ) Settlements paid in cash (1,290 ) (1,985 ) (3,275 ) Foreign currency translation — (3,463 ) (3,463 ) Balance at October 3, 2015 $ 87,985 $ 28,936 $ 116,921 The valuation methodologies used for pension plan assets measured at fair value have been applied consistently. Cash and cash equivalents consist of direct cash holdings and institutional short-term investment vehicles. Direct cash holdings are valued at cost, which approximates fair value. Institutional short-term investment vehicles are valued daily. Investments in U.S. Government obligations are valued by a pricing service based upon closing market prices at year end. Shares of registered investment companies are valued at net asset value of shares held by the plan at year end. Common stocks traded on national exchanges are valued at the last reported sales price. Investments denominated in foreign currencies are translated into U.S. dollars using the last reported exchange rate. Fixed income funds are valued using methods, such as dealer quotes, available trade information, spreads, bids and offers provided by a pricing vendor. Investments in insurance contracts are valued at contract value, which is the fair value of the underlying investment of the insurance company. Securities or other assets for which market quotations are not readily available or for which market quotations do not represent the value at the time of pricing (including certain illiquid securities) are fair valued in accordance with procedures established under the supervision and responsibility of the Custodian of that investment. Such procedures may include the use of independent pricing services or affiliated advisor pricing, which use prices based upon yields or prices of securities of comparable quality, coupon, maturity and type, indications as to values from dealers, operating data and general market conditions. The following table summarizes investments measured at fair value based on net asset value (NAV) per share as of October 3, 2015 : Unfunded Commitments Redemption Frequency Redemption Notice Period Interest in common collective trusts (1) $ — Daily, Weekly 0-5 days Insurance contracts and other (2) — Quarterly 90 days Limited partnerships (3) 12,300 Varies 15-45 days Total $ 12,300 (1) Interest in common collective trusts consist of pools of investments used by institutional investors to obtain exposure to equity and fixed income markets. Common collective trusts held by us invest primarily in investment grade fixed income securities, common stock and real property assets. (2) Insurance contracts and other includes hedge funds held by us, which invest primarily in global equity long and short positions. The primary strategy for the hedge funds is to seek risk-adjusted returns with volatility lower than the broad equity markets primarily through long and short investment opportunities in the global markets. (3) Investments in limited partnerships held by us invest primarily in emerging markets, equity and equity related securities. The strategy for the partnerships is to have exposure to certain markets or to securities that are judged to achieve superior earnings growth and/or judged undervalued relative to intrinsic value. The preceding methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although we believe the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. Pension expense for all defined benefit plans is as follows: U.S. Plans Non-U.S. Plans 2015 2014 2013 2015 2014 2013 Service cost $ 23,635 $ 21,571 $ 26,856 $ 6,087 $ 5,533 $ 4,874 Interest cost 34,031 33,354 28,818 4,814 5,984 5,750 Expected return on plan assets (47,136 ) (43,374 ) (41,340 ) (5,166 ) (4,487 ) (3,789 ) Amortization of prior service cost (credit) 149 149 8 (70 ) (57 ) (51 ) Amortization of actuarial loss 22,355 16,346 27,604 2,289 1,398 1,589 Settlement loss 54 37 — 77 — 245 Pension expense for defined benefit plans 33,088 28,083 41,946 8,031 8,371 8,618 Expense for the defined contribution plans were $13,621 , $13,196 and $11,223 for the U.S. Plans and $6,570 , $6,458 and $5,672 for the Non-U.S. Plans for 2015 , 2014 and 2013 , respectively. The estimated net prior service cost and net actuarial loss that will be amortized from accumulated other comprehensive loss into net periodic benefit cost for pension plans in 2016 are $111 and $28,778 , respectively. Benefits expected to be paid to the participants of the plans are: U.S. Plans Non-U.S. Plans 2016 $ 27,865 $ 5,576 2017 31,136 5,564 2018 33,965 5,901 2019 36,625 6,281 2020 39,725 5,938 Five years thereafter 249,182 41,127 We presently anticipate contributing approximately $68,000 to the U.S. plans and $6,700 to the non-U.S. plans in 2016 . We provide postretirement health care benefits to certain domestic retirees, who were hired prior to October 1, 1989. There are no plan assets. The transition obligation was fully amortized in 2013 . The changes in the accumulated benefit obligation of this unfunded plan for 2015 and 2014 are shown in the following table: October 3, 2015 September 27, 2014 Change in Accumulated Postretirement Benefit Obligation (APBO): APBO at prior year measurement date $ 15,331 $ 14,370 Service cost 226 225 Interest cost 576 624 Contributions by plan participants 2,228 1,725 Benefits paid (2,795 ) (2,513 ) Actuarial losses (gains) (3,034 ) 900 APBO at measurement date $ 12,532 $ 15,331 Funded status $ (12,532 ) $ (15,331 ) Accrued postretirement benefit liability $ 12,532 $ 15,331 Amount recognized in accumulated other comprehensive loss, before taxes: Actuarial losses (gains) 5,232 (2,303 ) Amount recognized in accumulated other comprehensive loss, before taxes $ 5,232 $ (2,303 ) The cost of the postretirement benefit plan is as follows: 2015 2014 2013 Service cost $ 226 $ 225 $ 292 Interest cost 576 624 549 Amortization of transition obligation — — 361 Amortization of actuarial gain (106 ) (261 ) — Net periodic postretirement benefit cost $ 696 $ 588 $ 1,202 As of the measurement date, the assumed discount rate used in the accounting for the postretirement benefit obligation was 3.9% in 2015 , 3.9% in 2014 and 4.5% in 2013 . As of the measurement date, the assumed discount rate used in the accounting for the net periodic postretirement benefit cost was 4.5% in 2015 , 4.5% in 2014 and 3.3% in 2013 . For measurement purposes, a 7.0% , 6.7% and 7.2% annual per capita rate of increase of medical and drug costs before age 65, medical costs after age 65 and drug costs after age 65, respectively, were assumed for 2016 , all gradually decreasing to 4.5% for 2028 and years thereafter. A one percentage point increase in this rate would increase our accumulated postretirement benefit obligation as of the measurement date in 2015 by $384 , while a one percentage point decrease in this rate would decrease our accumulated postretirement benefit obligation by $359 . There would be no material effect on the total service cost and interest cost components of the net periodic postretirement benefit cost given a one percentage point increase or decrease in this rate. Employee and management profit sharing reflects a discretionary payment based on our financial performance. Profit share expense was $13,188 , $22,030 and $14,950 in 2015 , 2014 and 2013 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The reconciliation of the provision for income taxes to the amount computed by applying the U.S. federal statutory tax rate to earnings before income taxes is as follows: 2015 2014 2013 Earnings before income taxes: Domestic $ 79,839 $ 107,395 $ 83,962 Foreign 104,132 111,716 80,559 Eliminations (137 ) (188 ) 485 Total $ 183,834 $ 218,923 $ 165,006 Federal statutory income tax rate 35.0 % 35.0 % 35.0 % Computed expected tax expense $ 64,342 $ 76,623 $ 57,752 Increase (decrease) in income taxes resulting from: R&D tax credits (3,046 ) (1,105 ) (3,271 ) Foreign tax rates (10,759 ) (13,034 ) (10,726 ) Export and manufacturing incentives (1,323 ) (1,803 ) (3,400 ) State taxes, net of federal benefit 1,534 2,236 1,921 Change in valuation allowance for deferred taxes 2,003 1,477 2,231 Change in enacted tax rates (590 ) (1,160 ) — Other (210 ) (2,509 ) 2 Income taxes $ 51,951 $ 60,725 $ 44,509 Effective income tax rate 28.3 % 27.7 % 27.0 % At October 3, 2015 , various subsidiaries had tax benefit carryforwards totaling $36,936 . Some of these tax benefit carryforwards do not expire and can be used to reduce current taxes otherwise due on future earnings of those subsidiaries. The change in the valuation allowance relates to tax benefit carryforwards reflecting recent and projected financial performance, tax planning strategies and statutory tax carryforward periods. No provision has been made for U.S. federal or foreign taxes on that portion of certain foreign subsidiaries’ undistributed earnings ( $860,229 at October 3, 2015 ) considered to be permanently reinvested. It is not practicable to determine the amount of tax that would be payable if these amounts were repatriated to the U.S. The components of income taxes are as follows: 2015 2014 2013 Current: Federal $ 12,065 $ 25,325 $ 29,345 Foreign 25,844 28,074 18,835 State 1,051 2,305 4,545 Total current 38,960 55,704 52,725 Deferred: Federal 10,800 5,034 (7,542 ) Foreign 882 (1,148 ) 914 State 1,309 1,135 (1,588 ) Total deferred 12,991 5,021 (8,216 ) Income taxes $ 51,951 $ 60,725 $ 44,509 Realization of deferred tax assets is dependent, in part, upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers projected future taxable income and tax planning strategies in making its assessment of the recoverability of deferred tax assets. The tax effects of temporary differences that generated deferred tax assets and liabilities are as follows: October 3, September 27, Deferred tax assets: Benefit accruals $ 210,241 $ 189,420 Inventory reserves 32,948 31,270 Tax benefit carryforwards 11,304 13,256 Contract loss reserves not currently deductible 9,049 9,943 Other accrued expenses 17,676 18,849 Total gross deferred tax assets 281,218 262,738 Less valuation allowance (6,642 ) (5,316 ) Total net deferred tax assets 274,576 257,422 Deferred tax liabilities: Differences in bases and depreciation of property, plant and equipment 162,661 164,817 Pension 70,273 70,124 Other — 486 Total gross deferred tax liabilities 232,934 235,427 Net deferred tax assets $ 41,642 $ 21,995 Net deferred tax assets and liabilities are included in the balance sheet as follows: October 3, September 27, Current assets $ 91,210 $ 92,390 Other assets 11,158 14,083 Other accrued liabilities (517 ) (547 ) Long-term liabilities (60,209 ) (83,931 ) Net deferred tax assets $ 41,642 $ 21,995 We have unrecognized tax benefits which, if ultimately recognized, will reduce our annual effective tax rate. A reconciliation of the total amounts of unrecognized tax benefits, excluding interest and penalties, is as follows: October 3, September 27, Balance at beginning of year $ 1,793 $ 1,533 Increases as a result of tax positions for prior years — 338 Reductions as a result of lapse of statute of limitations (609 ) — Settlement of tax positions — (78 ) Balance at end of year $ 1,184 $ 1,793 We are subject to income taxes in the U.S. and in various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require the application of significant judgment. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2011. The statute of limitations in several jurisdictions will expire in the next twelve months and we will have $700 of unrecognized tax benefits recognized if the statute of limitations expires without the relevant taxing authority examining the applicable returns. We record interest and penalties related to unrecognized tax benefits in income tax expense. We had accrued interest and penalties of $1,019 and $1,699 at October 3, 2015 and September 27, 2014 , respectively. We expensed interest of $208 and $348 for 2015 and 2014 , respectively.

Stockholders' Equity Note [Abstract]
Shareholders' Equity	Shareholders’ Equity Class A and Class B common stock share equally in our earnings and are identical with certain exceptions. Other than on matters relating to the election of directors or as required by law where the holders of Class A and Class B shares vote as separate classes, Class A shares have limited voting rights, with each share of Class A being entitled to one-tenth of a vote on most matters, and each share of Class B being entitled to one vote. Class A shareholders are entitled, subject to certain limitations, to elect at least 25% of the Board of Directors (rounded up to the nearest whole number) with Class B shareholders entitled to elect the balance of the directors. No cash dividend may be paid on Class B shares unless at least an equal cash dividend is paid on Class A shares. Class B shares are convertible at any time into Class A shares on a one-for-one basis at the option of the shareholder. The number of common shares issued reflects conversion of Class B to Class A of 11,087 in 2015 , 14,471 in 2014 and 37,936 in 2013 . Class A shares reserved for issuance at October 3, 2015 are as follows: Shares Conversion of Class B to Class A shares 7,641,095 2014 Long Term Incentive Plan 2,000,000 2008 Stock Appreciation Rights Plan 1,373,544 2003 Stock Option Plan 255,883 Class A shares reserved for issuance 11,270,522 We are authorized to issue up to 10,000,000 shares of preferred stock. The Board of Directors may authorize, without further shareholder action, the issuance of additional preferred stock which ranks senior to both classes of our common stock with respect to the payment of dividends and the distribution of assets on liquidation. The preferred stock, when issued, would have such designations relative to voting and conversion rights, preferences, privileges and limitations as determined by the Board of Directors.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity-Based Compensation	Equity-Based Compensation We have equity-based compensation plans that authorize the issuance of equity-based awards for shares of Class A and Class B common stock to directors, officers and key employees. Equity-based compensation grants are designed to reward long-term contributions to Moog and provide incentives for recipients to remain with Moog. Equity-based compensation expense is based on share-based payment awards that are ultimately expected to vest. Vesting requirements vary for directors, officers and key employees. In general, options and stock appreciation rights (SARs) granted to outside directors vest one year from the date of grant, options granted to officers vest on various schedules, options granted to key employees vest in equal annual increments over a period of five years from the date of grant and SARs granted to officers and key employees vest in equal annual installments over a period of three years from the date of grant. The fair value of equity-based awards granted was estimated on the date of grant using the Black-Scholes option-pricing model. The following table provides the range of assumptions used to value equity-based awards and the weighted-average fair value of the awards granted. 2015 2014 2013 Expected volatility 24% - 38% 29% - 39% 34% - 40% Risk-free rate .9% - 1.9% .7% - 2.0% .4% - 1.1% Expected dividends — % — % — % Expected term 3-7 years 3-7 years 3-7 years Weighted-average fair value of awards granted $ 28.71 $ 23.74 $ 14.10 To determine expected volatility, we generally use historical volatility based on weekly closing prices of our Class A common stock over periods that correlate with the expected terms of the awards granted. The risk-free rate is based on the United States Treasury yield curve at the time of grant for the appropriate term of the awards granted. Expected dividends are based on our history and expectation of dividend payouts. The expected term of equity-based awards is based on vesting schedules, expected exercise patterns and contractual terms. On January 7, 2015, shareholders approved the 2014 Long Term Incentive Plan. The 2014 Long Term Incentive Plan authorizes the issuance of a total of 2,000,000 shares of either Class A or Class B common stock. The 2014 Long Term Incentive Plan is intended to provide a flexible framework that permits the development and implementation of a variety of stock-based programs that base awards on key performance metrics as well as align our long term incentive compensation with our peers and shareholder interests. The 2008 Stock Appreciation Rights Plan (2008 Plan) authorizes the issuance of 4,000,000 SARs, which represent the right to receive shares of Class A common stock. The exercise price of the SARs, determined by a committee of the Board of Directors, may not be less than the fair market value of the Class A common stock on the grant date. The number of shares received upon exercise of a SAR is equal in value to the difference between the fair market value of the Class A common stock on the exercise date and the exercise price of the SAR. The term of a SAR may not exceed ten years from the grant date. The 2003 Stock Option Plan (2003 Plan) authorizes the issuance of options for 1,350,000 shares of Class A common stock. The 1998 Stock Option Plan (1998 Plan) authorizes the issuance of options for 2,025,000 shares of Class A common stock. Under the terms of the plans, options may be either incentive or non-qualified. Options outstanding as of October 3, 2015 consisted of both incentive options and non-qualified options. The exercise price, determined by a committee of the Board of Directors, may not be less than the fair market value of the Class A common stock on the grant date. Options become exercisable over periods not exceeding ten years.

Segment Reporting, Disclosure of Entity's Reportable Segments [Abstract]
Segments	Segments During 2015, we made a change to our segment reporting. Components now includes the sensor and handpieces product line, which we previously included in the Medical Devices segment. This product line consists of manufactured ultrasonic and optical sensors as well as surgical handpieces distributed to medical OEMs. Since the customer base is different from the sale of medical pumps directly to end users, the chief operating decision maker is now reviewing performance and assessing the allocation of resources of this product line as part of the Components segment. Sales of sensors and handpieces were $25,079 , $24,763 and $23,144 in 2015 , 2014 and 2013 , respectively. All amounts, including goodwill, have been restated to present sensors and handpieces within Components. Goodwill was allocated based on the relative fair value of the sensor and handpieces business compared to the Medical Devices segment prior to its transfer to Components. Aircraft Controls. We design, manufacture and integrate primary and secondary flight controls for military and commercial aircraft and provide aftermarket support. Our systems are used on both development and production programs in large commercial transports, supersonic fighters, multi-role military aircraft, business jets and rotorcraft. We also supply ground-based navigation aids. We are currently working on the KC-46 military air refueling tanker on the military side, and the Airbus A350XWB, COMAC C919, the Bell 525 Helicopter and the Embraer E-Jet E2 family on the commercial side. Typically development programs require concentrated periods of research and development by our engineering teams, while production programs are generally long-term manufacturing efforts that extend for as long as the aircraft builder receives new orders. In the past few years, a number of significant programs have begun to transition from the development phase to initial low-rate production, including the Lockheed Martin F-35 Joint Strike Fighter on the military side, and the Boeing 787, Gulfstream G650 and G280 on the commercial side. In terms of mature production programs, our large military programs include the F/A-18E/F Super Hornet, the V-22 Osprey tiltrotor and the Black Hawk UH-60/Seahawk SH-60 helicopter, while our large commercial production programs include the full line of Boeing 7-series aircraft, Airbus A330 and A380 and a variety of business jets. Aftermarket sales, which represented 30% , 32% and 32% of 2015 , 2014 and 2013 sales, respectively, for this segment consist of the maintenance, repair, overhaul and parts supply for both military and commercial aircraft. Further, we sell spare parts and line replaceable units to both military and commercial customers that they store throughout the world in order to minimize down time. Space and Defense Controls. We provide controls for satellites, space vehicles, launch vehicles, armored combat vehicles, tactical and strategic missiles, security and surveillance and other defense applications. Within our space market, we design, manufacture and integrate commercial and military satellite positioning controls. These propulsion and actuation systems and the components control attitude, orbit insertion, solar panels and antennas. We also design, manufacture and integrate steering and propulsion controls for space launch vehicles, such as the Atlas, Delta and Ariane platforms. Additionally, we design and manufacture spaceflight electronics and software. We are also developing new control products and systems for a variety of programs related to manned spaceflight including: NASA's new Space Launch System, Multi-Purpose Crew Vehicle and Soft Capture System. Within our defense market, we design controls for gun aiming, stabilization and automatic ammunition loading for armored combat vehicles for a variety of domestic and international customers. We also design controls for steering tactical and strategic missiles including: Lockheed Martin's Hellfire ® , the U.S. National Missile Defense Agency's Ballistic Missile Defense initiatives and Raytheon's TOW and Trident missiles.

Our sensor and surveillance systems products are used in both military and commercial applications such as electrical grid and other critical infrastructure protection applications. Industrial Systems. Our Industrial Systems segment serves a global customer base across a variety of markets. In the industrial automation market, we design manufacture and integrate systems for industrial automation customers for applications in injection and blow molding machinery, metal forming presses and heavy industry customers in steel and aluminum production. Our systems allow for precise controls of critical parameters in the industrial manufacturing processes, using both hydraulic and electric technology. Other industrial automation markets we serve include material handling and paper and lumber mills. In the energy market, we supply solutions for power generation applications which allow for precise control and greater safety of fuel metering and guide vane positioning on steam and gas turbines. We also design and manufacture high reliability systems and components for applications in oil and gas exploration and production, including downhole drilling, topside and subsea environments, as well as electric pitch controls and blade monitoring systems for wind turbines. In the simulation and test market, we supply electromechanical motion simulation bases for the flight simulation and training markets, as well as medical training simulators. For the test markets, we supply custom test systems and controls for automotive, structural and fatigue testing. Components. Our Components segment serves many of the same markets as our other segments. Our Components segment’s three largest product categories are slip rings, fiber optic rotary joints and motors. Slip rings and fiber optic rotary joints use sliding contacts and optical technology to allow unimpeded rotation while delivering power and data through a rotating interface. They come in a range of sizes that allow them to be used in many applications, including diagnostic imaging CT scan medical equipment, blade de-icing and data transfer for rotorcraft, remotely operated vehicles and floating platforms for offshore oil exploration, surveillance cameras, forward-looking infrared camera installations and radar pedestals, satellites, missiles and wind turbines. Our motors are used in an equally broad range of markets, many of which are the same as for slip rings. We design and manufacture a series of fractional horsepower brushless motors that provide extremely low acoustic noise and reliable long life operation, with the largest market being sleep apnea equipment. Industrial customers use our motors for material handling and electric pumps. Military programs use our motors for gimbals, missiles and radar pedestals. Our Components’ segment's other product lines include electromechanical actuators for military, aerospace and commercial applications, fiber optic modems that provide electrical-to-optical conversion of communication and data signals, avionic instrumentation, subsea navigation and control systems, acoustic sensors and sonars for energy and marine applications including remotely-operated underwater vehicles, optical switches and resolvers, ultrasonic and optical sensors and surgical hand pieces used in medical applications. Medical Devices. Our Medical Devices segment operates within two areas: infusion therapy and enteral clinical nutrition. For infusion therapy, our primary products are electronic ambulatory infusion pumps along with the associated administration sets. Applications of these products include hydration, nutrition, patient-controlled analgesia, local anesthesia, chemotherapy and antibiotics. We manufacture and distribute a complete line of portable pumps, stationary pumps and disposable sets that are used in the delivery of enteral nutrition for patients in their own homes, hospitals and long-term care facilities.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	Commitments and Contingencies From time to time, we are involved in legal proceedings. We are not a party to any pending legal proceedings which management believes will result in a material adverse effect on our financial condition, results of operations or cash flows. We are engaged in administrative proceedings with governmental agencies and legal proceedings with governmental agencies and other third parties in the normal course of our business, including litigation under Superfund laws, regarding environmental matters. We believe that adequate reserves have been established for our share of the estimated cost for all currently pending environmental administrative or legal proceedings and do not expect that these environmental matters will have a material adverse effect on our financial condition, results of operations or cash flows. In the ordinary course of business we could be subject to ongoing claims or disputes from our customers, the ultimate settlement of which could have a material adverse impact on our consolidated results of operations. While the receivables and any loss provisions recorded to date reflect management's best estimate of the projected costs to complete a given project, there is still significant effort required to complete the ultimate deliverable. Future variability in internal cost and as well as future profitability is dependent upon a number of factors including deliveries, performance and government budgetary pressures. The inability to achieve a satisfactory contractual solution, further unplanned delays, additional developmental cost growth or variations in any of the estimates used in the existing contract analysis could lead to further loss provisions. Additional losses could have a material adverse impact on our financial condition, results of operations or cash flows in the period in which the loss may be recognized. We lease certain facilities and equipment under operating lease arrangements. These arrangements may include fair market renewal or purchase options. Rent expense under operating leases amounted to $27,764 in 2015 , $26,238 in 2014 and $28,070 in 2013 . Future minimum rental payments required under non-cancellable operating leases are $21,169 in 2016 , $18,959 in 2017 , $16,395 in 2018 , $13,894 in 2019 , $10,129 in 2020 and $46,009 thereafter. We are contingently liable for $16,773 of standby letters of credit issued by a bank to third parties on our behalf at October 3, 2015 . Purchase commitments outstanding at October 3, 2015 are $605,316 , including $19,627 for property, plant and equipment.

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Oct. 03, 2015
Accounting Policies [Abstract]
Consolidation	Consolidation: The consolidated financial statements include the accounts of Moog Inc. and all of our U.S. and foreign subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year: Our fiscal year ends on the Saturday that is closest to September 30. The consolidated financial statements include 53 weeks for the year ended October 3, 2015 and 52 weeks for the years ended September 27, 2014 and September 28, 2013 .
Operating Cycle	Operating Cycle: Consistent with industry practice, aerospace and defense related inventories, unbilled recoverable costs and profits on long-term contract receivables, customer advances and contract loss reserves include amounts relating to contracts having long production and procurement cycles, portions of which are not expected to be realized or settled within one year.
Foreign Currency Translation	Foreign Currency Translation: Assets and liabilities of subsidiaries that prepare financial statements in currencies other than the U.S. dollar are translated using rates of exchange as of the balance sheet date and the statements of earnings are translated at the average rates of exchange for each reporting period.
Use Of Estimates	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and assumptions.
Percentage of Completion Method for Contracts	Percentage of completion method for contracts : Revenue representing 33% , 34% and 33% of 2015 , 2014 and 2013 sales, respectively, was accounted for using the percentage of completion, cost-to-cost method of accounting. This method of revenue recognition is predominantly used within the Aircraft Controls and Space and Defense Controls segments due to the contractual nature of the business activities, with the exception of their respective aftermarket activities. The contractual arrangements are either firm fixed-price or cost-plus contracts and are primarily with the U.S. Government or its prime subcontractors, foreign governments or commercial aircraft manufacturers, including Boeing and Airbus. The nature of the contractual arrangements includes customers’ requirements for delivery of hardware as well as funded nonrecurring development work in anticipation of follow-on production orders. Revenue on contracts using the percentage of completion, cost-to-cost method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total estimated contract revenue, less cumulative revenue recognized in prior periods. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for substantially all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations. Occasionally, it is appropriate to combine or segment contracts. Contracts are combined in those limited circumstances when they are negotiated as a package in the same economic environment with an overall profit margin objective and constitute, in essence, an agreement to do a single project. In such cases, revenue and costs are recognized over the performance period of the combined contracts as if they were one. Contracts are segmented in limited circumstances if the customer had the right to accept separate elements of the contract and the total amount of the proposals on the separate components approximated the amount of the proposal on the entire project. For segmented contracts, revenue and costs are recognized as if they were separate contracts over the performance periods of the individual elements or phases. Contract costs include only allocable, allowable and reasonable costs, as determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards for applicable U.S. Government contracts, and are included in cost of sales when incurred. The nature of these costs includes development engineering costs and product manufacturing costs including direct material, direct labor, other direct costs and indirect overhead costs. Contract profit is recorded as a result of the revenue recognized less costs incurred in any reporting period. Amounts representing performance incentives, penalties, contract claims or change orders are considered in estimating revenues, costs and profits when they can be reliably estimated and realization is considered probable. Revenue recognized on contracts for unresolved claims or unapproved contract change orders was not material for 2015 , 2014 or 2013 . For contracts with anticipated losses at completion, a provision for the entire amount of the estimated remaining loss is charged against income in the period in which the loss becomes known. Contract losses are determined considering all direct and indirect contract costs, exclusive of any selling, general or administrative cost allocations that are treated as period expenses. Loss reserves are more common on firm fixed-price contracts that involve, to varying degrees, the design and development of new and unique controls or control systems to meet the customers’ specifications.
Revenue Recognition	As units are delivered or services are performed : In 2015 , 67% of our sales were recognized as units were delivered or as service obligations were satisfied. Revenue is recognized when the risks and rewards of ownership and title to the product are transferred to the customer. When engineering or similar services are performed, revenue is recognized upon completion of the obligation including any delivery of engineering drawings or technical data. This method of revenue recognition is predominantly used within the Industrial Systems, Components and Medical Devices segments, as well as with aftermarket activity. Profits are recorded as costs are relieved from inventory and charged to cost of sales and as revenue is recognized. Inventory costs include all product manufacturing costs such as direct material, direct labor, other direct costs and indirect overhead cost allocations. Revenue Recognition: We recognize revenue using either the percentage of completion method for contracts or as units are delivered or services are performed.
Shipping and Handling Cost	Shipping and Handling Costs: Shipping and handling costs are included in cost of sales.
Research and Development	Research and Development: Research and development costs are expensed as incurred and include salaries, benefits, consulting, material costs and depreciation.
Bid And Proposal Costs	Bid and Proposal Costs: Bid and proposal costs are expensed as incurred and classified as selling, general and administrative expenses.
Equity-Based Compensation	Equity-Based Compensation: Equity-based compensation expense is included in selling, general and administrative expenses.
Earnings Per Share	Earnings Per Share: Basic and diluted weighted-average shares outstanding are as follows: 2015 2014 2013 Basic weighted-average shares outstanding 38,945,880 44,362,412 45,335,336 Dilutive effect of equity-based awards 388,640 590,025 488,384 Diluted weighted-average shares outstanding 39,334,520 44,952,437 45,823,720
Cash and Cash Equivalents	Cash and Cash Equivalents: All highly liquid investments with an original maturity of three months or less are considered cash equivalents.
Allowance For Doubtful Accounts	Allowance for Doubtful Accounts: The allowance for doubtful accounts is based on our assessment of the collectibility of customer accounts. The allowance is determined by considering factors such as historical experience, credit quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.
Inventories	Inventories: Inventories are stated at the lower-of-cost-or-market with cost determined on the first-in, first-out (FIFO) method of valuation.
Property, Plant And Equipment	Property, Plant and Equipment: Property, plant and equipment are stated at cost. Plant and equipment are depreciated principally using the straight-line method over the estimated useful lives of the assets, generally 40 years for buildings, 15 years for building improvements, 12 years for furniture and fixtures, 10 years for machinery and equipment, 8 years for tooling and test equipment and 3 to 5 years for computer hardware and software. Leasehold improvements are amortized on a straight-line basis over the term of the lease or the estimated useful life of the asset, whichever is shorter.
Goodwill	Goodwill: We test goodwill for impairment at the reporting unit level on an annual basis or more frequently if an event occurs or circumstances change that indicate that the fair value of a reporting unit is likely to be below its carrying amount. We also test goodwill for impairment when there is a change in reporting units. We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or selected reporting units. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test instead of a qualitative test for any or all of our reporting units. Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. We use the discounted cash flow method to estimate the fair value of our reporting units. The discounted cash flow method incorporates various assumptions, the most significant being projected revenue growth rates, operating margins and cash flows, the terminal growth rate and the weighted-average cost of capital. If the carrying value of the reporting unit exceeds its fair value, goodwill is considered impaired and any loss must be measured. To determine the amount of the impairment loss, the implied fair value of goodwill is determined by assigning a fair value to all of the reporting unit's assets and liabilities, including any unrecognized intangible assets, as if the reporting unit had been acquired in a business combination at fair value. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss would be recognized in an amount equal to that excess. We recorded a $38,200 goodwill impairment charge in 2013 in our Medical Devices reporting unit. There were no impairment charges recorded in 2015 or 2014 .
Acquired Intangible Assets	Acquired Intangible Assets: Acquired identifiable intangible assets are recorded at cost and are amortized over their estimated useful lives.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets: Long-lived assets, including acquired identifiable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. We use undiscounted cash flows to determine whether impairment exists and measure any impairment loss using discounted cash flows. In 2014, we recorded a $739 impairment charge in our Industrial Systems segment related to intangible assets from a product line we decided to exit. We also recorded a $1,296 impairment charge in our Medical Devices segment related to equipment from a product line we are no longer pursuing. Both of these charges are included as restructuring in the consolidated statements of earnings. In 2015, we recorded impairment charges of $2,432 in our Industrial Systems segment, primarily related to intangible assets from a wind energy product line that we decided to exit, which is included as other expense. We also recorded an additional $472 impairment charge related to intangible assets on the product line we decided to exit in 2014, which is included as restructuring in the consolidated statement of earnings. There were no impairment charges recorded in 2013 .
Product Warranties	Product Warranties: In the ordinary course of business, we warrant our products against defect in design, materials and workmanship typically over periods ranging from twelve to sixty months. We determine warranty reserves needed by product line based on historical experience and current facts and circumstances. Activity in the warranty accrual is summarized as follows: 2015 2014 2013 Warranty accrual at beginning of year $ 19,953 $ 17,429 $ 18,859 Warranties issued during current year 9,666 12,611 9,019 Adjustments to pre-existing warranties (2,416 ) (2,037 ) (1,911 ) Reductions for settling warranties (7,448 ) (7,759 ) (8,507 ) Foreign currency translation (1,095 ) (291 ) (31 ) Warranty accrual at end of year $ 18,660 $ 19,953 $ 17,429
Financial Instruments	Financial Instruments: Our financial instruments consist primarily of cash and cash equivalents, receivables, notes payable, accounts payable, long-term debt, interest rate swaps and foreign currency forwards. The carrying values for our financial instruments approximate fair value with the exception at times of long-term debt. We do not hold or issue financial instruments for trading purposes. We carry derivative instruments on the consolidated balance sheets at fair value, determined by reference to quoted market prices. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. Our use of derivative instruments is generally limited to cash flow hedges of certain interest rate risks and minimizing foreign currency exposure on foreign currency transactions, which are typically designated in hedging relationships, and intercompany balances, which are not designated as hedging instruments. Cash flows resulting from forward contracts are accounted for as hedges of identifiable transactions or events and classified in the same category as the cash flows from the items being hedged.
Recent Accounting Pronouncements	Recent Accounting Pronouncements : In March 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Group of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU is intended to eliminate diversity in practice on the release of cumulative translation adjustments into net income when a parent either sells part or all of its investment in a foreign entity, or when it no longer holds a controlling financial interest. In addition, the amendments resolve the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The provisions of this ASU are effective for fiscal years beginning after December 15, 2013 and interim periods within those fiscal years. We adopted this amendment in the first quarter of 2015. The adoption of this standard did not have a material impact on our financial statements. In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase to Maturity Transactions, Repurchase Financings and Disclosures.” This ASU changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting, requires certain disclosures for transactions accounted for as sales and requires certain disclosures for other transactions accounted for as secured borrowings. The provisions of this ASU are effective for fiscal years beginning after December 15, 2014 and for interim periods beginning after March 15, 2015. We adopted this amendment in the third quarter of 2015. The adoption of this standard did not have a material impact on our financial statements. In April 2015, the FASB issued ASU No. 2015-04, “Compensation - Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer’s Defined Benefit Obligation and Plan Assets.” This ASU permits an entity to measure defined benefit plan assets and obligations using the month-end that is closest to the entity’s fiscal year-end and apply that consistently from year to year. This practical expedient would then be applied to all plans if an entity has more than one plan. Further, if a contribution or other significant event occurs between the month-end date used to measure defined benefit plan assets and obligations and an entity’s fiscal year-end, the entity should adjust the measurement of the defined benefit plan assets and obligations to reflect the effects of those contributions and other significant events. The provisions of this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted, and prospective application is required. We adopted this standard in 2015, and changed our method of measuring plan assets and obligations related to our defined benefit plans. This change simplifies our reporting while maintaining the usefulness of information presented in our financial statements. The adoption of this standard did not have a material impact on our financial statements.
