Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared by management in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments consisting of normal recurring adjustments considered necessary for the fair presentation of results for the interim period have been included. The results of operations for the three and six months ended March 30, 2019 are not necessarily indicative of the results expected for the full year. The accompanying unaudited consolidated condensed financial statements should be read in conjunction with the financial statements and notes thereto included in our Form 10-K for the fiscal year ended September 29, 2018 . All references to years in these financial statements are to fiscal years. Certain prior year amounts have been reclassified to conform to current year's presentation. Management does not consider the amounts reclassified to be material. Recent Accounting Pronouncements Adopted Standard Description Financial Statement Effect or Other Significant Matters ASU no. 2014-09 Revenue from Contracts with Customers The standard requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The provisions of the standard, as well as all subsequently issued clarifications to the standard, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The standard can be adopted using either a full retrospective or modified retrospective approach. We adopted this standard using the modified retrospective method, under which prior years' results are not restated, but supplemental information is provided in our disclosures to present 2019 results before effect of the standard. In addition, a cumulative adjustment was made to shareholders' equity at the beginning of 2019. Supplemental information is provided in our disclosures to present 2019 results before effect of the standard. Date adopted: ASU no. 2017-07 Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost The standard amends existing guidance on the presentation of net periodic benefit cost in the income statement and what qualifies for capitalization on the balance sheet. The provisions of the standard are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period. The amendment requires income statement presentation provisions to be applied retrospectively and capitalization in assets provisions to be applied prospectively. We adopted this standard retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the Consolidated Condensed Statement of Earnings. Supplemental information is provided in our disclosures to present 2018 results before effect of the standard. Date adopted: Recent Accounting Pronouncements Not Yet Adopted Standard Description Financial Statement Effect or Other Significant Matters ASU no. 2016-02 Leases (and all related ASUs) The standard requires most lease arrangements to be recognized in the balance sheet as lease assets and lease liabilities. The standard also requires additional disclosures about the leasing arrangements. The provisions of the standard are effective for fiscal years beginning after December 15, 2018 and interim periods within those years. Early adoption is permitted. We are currently evaluating the effect on our financial statements and related disclosures. Planned date of adoption: Q1 2020 ASU no. 2017-12 Targeted Improvements to Accounting for Hedging Activities The standard expands the hedging strategies eligible for hedge accounting, while simplifying presentation and disclosure by eliminating separate measurement and reporting of hedge ineffectiveness. The provisions of the standard are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effect on our financial statements and related disclosures. Planned date of adoption: Q1 2020 ASU no. 2018-15 Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract The standard amends ASC 350 to include in its scope implementation costs of a Cloud Computing Arrangement (CCA) that is a service contract and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA that is considered a service contract. The ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The amendments should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently evaluating the effect on our financial statements and related disclosures. Planned date of adoption: We consider the applicability and impact of all ASUs. ASUs not listed above were assessed and determined to be either not applicable, or had or are expected to have minimal impact on our financial statements and related disclosures. In accordance with SEC Final Rule Release No. 33-10532, we have adopted Rule 3-04 of Regulation S-X during the first quarter of 2019 and have disclosed changes in the Consolidated Condensed Statement of Shareholders' Equity and the amount of dividends per share for each class of shares for all periods presented. Refer to Note 16, Earnings per Share and Dividends. Impact of Recent Accounting Pronouncements Adopted On September 30, 2018, we adopted ASC 606: Revenue from Contracts with Customers and the related amendments (ASC 606), using the modified retrospective method, as described above. ASC 606 was applied to contracts that were not completed as of September 29, 2018.

Revenue from Contract with Customer [Abstract]
Revenue Recognition and Contracts with Customers	Revenue from Contracts with Customers We recognize revenue from contracts with customers using the five-step model prescribed in ASC 606. The first step is identifying the contract. The identification of a contract with a customer requires an assessment of each party’s rights and obligations regarding the products or services to be transferred, including an evaluation of termination clauses and presently enforceable rights and obligations. Each party’s rights and obligations and the associated terms and conditions are typically determined in purchase orders. For sales that are governed by master supply agreements under which provisions define specific program requirements, purchase orders are issued under these agreements to reflect presently enforceable rights and obligations for the units of products and services being purchased. Contracts are sometimes modified to account for changes in contract specifications and requirements. When this occurs, we assess the modification as prescribed in ASC 606 and determine whether the existing contract needs to be modified (and revenue cumulatively caught up), whether the existing contract needs to be terminated and a new contract needs to be created, or whether the existing contract remains and a new contract needs to be created. This is determined based on the rights and obligations within the modification as well as the associated transaction price. The next step is identifying the performance obligations. A performance obligation is a promise to transfer goods or services to a customer that is distinct in the context of the contract, as defined by ASC 606. We identify a performance obligation for each promise in a contract to transfer a distinct good or service to the customer. As part of our assessment, we consider all goods and/or services promised in the contract, regardless of whether they are explicitly stated or implied by customary business practices. The products and services in our contracts are typically not distinct from one another due to their complexity and reliance on each other or, in many cases, we provide a significant integration service. Accordingly, many of our contracts are accounted for as one performance obligation. In limited cases, our contracts have more than one distinct performance obligation, which occurs when we perform activities that are not highly complex or interrelated or involve different product life cycles. Warranties are provided on certain contracts, but do not typically provide for services beyond standard assurances and are therefore not distinct performance obligations under ASC 606. The third step is determining the transaction price, which represents the amount of consideration we expect to be entitled to receive from a customer in exchange for providing the goods or services. There are times when this consideration is variable, for example a volume discount, and must be estimated. Sales, use, value-added, and excise taxes are excluded from the transaction price, where applicable. The fourth step is allocating the transaction price. The transaction price must be allocated to the performance obligations identified in the contract based on relative stand-alone selling prices when available, or an estimate for each distinct good or service in the contract when standalone prices are not available. Our contracts with customers generally require payment under normal commercial terms after delivery. Payment terms are typically within 30 to 60 days of delivery. The timing of satisfaction of our performance obligations does not significantly vary from the typical timing of payment. The final step is the recognition of revenue. We recognize revenue as the performance obligations are satisfied. ASC 606 provides guidance to help determine if we are satisfying the performance obligation at a point in time or over time. In determining when performance obligations are satisfied, we consider factors such as contract terms, payment terms and whether there is an alternative use of the product or service. In essence, we recognize revenue when or as control of the promised goods or services transfer to the customer. Under ASC 606, revenue recognized over time using the cost-to-cost method of accounting for the three and six months ended March 30, 2019 was 65% and 64% , respectively. The over time method of revenue recognition is predominantly used in Aircraft Controls and Space and Defense Controls. We use this method for U.S. Government contracts and repair and overhaul arrangements as we are creating or enhancing assets that the customer controls as the assets are being created or enhanced. In addition, many of our large commercial contracts qualify for over time accounting as our performance does not create an asset with an alternative use and we have enforceable right to payment for performance completed to date. Our over time contracts are primarily firm fixed price. Revenue is recognized on contracts using the cost-to-cost method of accounting 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. We believe that cumulative costs incurred to date as a percentage of estimated total contract costs at completion is an appropriate measure of progress toward satisfaction of performance obligations as this measure most accurately depicts the progress of our work and transfer of control to our customers. 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. For the three and six months ended March 30, 2019 , we recognized lower revenues of $1,321 and higher revenues of $10,438 , respectively, for adjustments made to performance obligations satisfied (or partially satisfied) in previous periods. Contract costs include only allocable, allowable and reasonable costs which are included in cost of sales when incurred. For applicable U.S. Government contracts, contract costs are determined in accordance with the Federal Acquisition Regulations and the related Cost Accounting Standards. The nature of these costs includes development engineering costs and product manufacturing costs such as 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. Variable consideration and contract modifications, such as 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 the three and six months ended March 30, 2019 . As of March 30, 2019 , we had contract and contract-related loss reserves of $49,383 . 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. Contract-related loss reserves are recorded for the additional work needed on completed and delivered products in order for them to meet contract specifications. In accordance with ASC 606, we calculate contract losses at the contract level, versus the performance obligation level. For the three and six months ended March 30, 2019 , 35% and 36% of revenue, respectively, was recognized at the point in time control transferred to the customer. This method of revenue recognition is used most frequently in Industrial Systems. We use this method for commercial contracts in which the asset being created has an alternative use. We determine the point in time control transfers to the customer by weighing the five indicators provided by ASC 606 - the entity has a present right to payment; the customer has legal title; the customer has physical possession; the customer has the significant risks and rewards of ownership; and the customer has accepted the asset. When control has transferred to the customer, profit is generated as cost of sales is recorded 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 are considered costs to fulfill a contract and not considered performance obligations. They are included in cost of sales as incurred. Contract Assets and Liabilities Unbilled receivables (contract assets) primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. These are included as Receivables on the Consolidated Condensed Balance Sheets. Contract advances (contract liabilities) relate to payments received from customers in advance of the satisfaction of performance obligations for a contract. We do not consider contract advances to be significant financing components as the intent of these payments in advance are for reasons other than providing a significant financing benefit and are customary in our industry. Total contract assets and contract liabilities as of March 30, 2019 are as follows: March 30, 2019 September 30, 2018 Unbilled receivables $ 430,901 $ 405,610 Contract advances 169,836 152,608 Net contract assets $ 261,065 $ 253,002 The increase in contract assets reflects the net impact of additional unbilled revenues recorded in excess of revenue recognized during the period. The increase in contract liabilities reflects the net impact of additional deferred revenues recorded in excess of revenue recognized during the period. For the three and six months ended March 30, 2019 , we recognized $46,078 and $93,586 of revenue, respectively, that was included in the contract liability balance at the beginning of the period. Remaining Performance Obligations As of March 30, 2019 , the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied), also known as backlog, was approximately $2,230,000 . We expect to recognize approximately 73% of that amount as sales over the next twelve months and the balance thereafter. Disaggregation of Revenue

Acquisitions, Divestitures and Equity Method Investments	Acquisitions, Divestitures and Equity Method Investments In the first quarter of 2019, we sold a non-core business of our Industrial Systems segment for $4,191 in cash and recorded a gain in other income of $2,641 . On April 30, 2018, we acquired Electro-Optical Imaging, a designer and manufacturer of video trackers and imaging products, located in Florida, for a purchase price, net of acquired cash, of $5,442 . This operation is included in our Space and Defense Controls segment. On March 29, 2018, we acquired a 100% ownership interest in VUES Brno s.r.o ("Vues") located in the Czech Republic, which included a 74% ownership interest in a subsidiary located in Germany. The purchase price, net of acquired cash, was $64,140 , consisting of $42,961 in cash and $21,179 of assumed debt. VUES designs and manufactures electric motors and generators, and provides customized solutions. On September 6, 2018, we acquired the remaining 26% noncontrolling interest for $1,843 in cash. The difference between the cash paid and the adjustment to the noncontrolling interest is reflected in additional paid-in capital. This operation is included in our Industrial Systems segment. The purchase price allocations for this acquisition are complete. On October 3, 2017, we, in collaboration with SIA Engineering Company, announced the joint venture company, Moog Aircraft Services Asia ("MASA"), in Singapore, of which we currently hold a 51% ownership. MASA is intended to provide maintenance, repair and overhaul services for our manufactured flight control systems. As we hold a majority ownership in MASA, but share voting control, we are accounting for this investment using the equity method. As of March 30, 2019 , we have made total contributions of $5,100

Our U.S. revolving credit facility has a capacity of $1,100,000 and provides an expansion option, which permits us to request an increase of up to $200,000 to the credit facility 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. We are in compliance with all covenants. The SECT has a revolving credit facility with a borrowing capacity of $35,000 , maturing on July 26, 2020. Interest is based on LIBOR plus an applicable margin. A commitment fee is also charged based on a percentage of the unused amounts available and is not material. At March 30, 2019 , we had $300,000 principal amount of 5.25% senior notes due December 1, 2022 with interest paid semiannually on June 1 and December 1 of each year. 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 Securitization Program, effectively increasing our borrowing capacity by up to $130,000 , was extended on October 30, 2018 and now matures on October 30, 2020 . 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 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 March 30, 2019 , our minimum borrowing requirement was $104,000

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 March 30, 2019 , we had interest rate swaps with notional amounts totaling $105,000 . The interest rate swaps effectively convert this amount of variable-rate debt to fixed-rate debt at 2.99% , including the applicable margin of 1.63% as of March 30, 2019 . 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 through June 23, 2020 . We use foreign currency contracts as cash flow hedges to effectively fix the exchange rates on future payments and revenue. To mitigate exposure in movements between various currencies, including the Philippine peso, the British pound and the Czech koruna, we had outstanding foreign currency forwards with notional amounts of $69,048 at March 30, 2019 . These contracts mature at various times through February 26, 2021 . We use forward currency contracts to hedge our net investment in certain foreign subsidiaries. As of March 30, 2019 , we had no outstanding net investment hedges. These interest rate swaps, foreign currency contracts and net investment hedges are recorded in the Consolidated Condensed Balance Sheets at fair value and the related gains or losses are deferred in Shareholders’ Equity as a component of Accumulated Other Comprehensive Income (Loss) (AOCIL). These deferred gains and losses are reclassified into the Consolidated Condensed Statements of Earnings, as necessary, during the periods in which the related payments or receipts affect earnings. However, to the extent the interest rate swaps and foreign currency contracts are not perfectly effective in offsetting the change in the value of the payments and revenue being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was not material in the first six months of 2019 or 2018 . Derivatives not designated as hedging instruments We also have foreign currency exposure on balances, primarily intercompany, that are denominated in foreign currencies and are adjusted to current values using period-end exchange rates. The resulting gains or losses are recorded in the Consolidated Condensed Statements of Earnings. To minimize foreign currency exposure, we had foreign currency contracts with notional amounts of $78,359 at March 30, 2019 . The foreign currency contracts are recorded in the Consolidated Condensed Balance Sheets at fair value and resulting gains or losses are recorded in the Consolidated Condensed Statements of Earnings. We recorded the following gains or losses on foreign currency contracts which are included in other income or expense and generally offset the gains or losses from the foreign currency adjustments on the intercompany balances that are also included in other income or expense: Three Months Ended Six Months Ended March 30, March 31, March 30, March 31, Net gain (loss) $ 2,419 $ (2,381 ) $ 769 $ (3,009 ) Summary of derivatives The fair value and classification of derivatives is summarized as follows: March 30, September 29, Derivatives designated as hedging instruments: Foreign currency contracts Other current assets $ 690 $ 659 Foreign currency contracts Other assets 178 41 Interest rate swaps Other current assets 673 1,444 Interest rate swaps Other assets 24 322 Total asset derivatives $ 1,565 $ 2,466 Foreign currency contracts Other accrued liabilities $ 703 $ 1,842 Foreign currency contracts Other long-term liabilities 63 464 Total liability derivatives $ 766 $ 2,306 Derivatives not designated as hedging instruments: Foreign currency contracts Other current assets $ 376 $ 285 Foreign currency contracts Other accrued liabilities $ 477 $ 87

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. 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 March 30, September 29, Foreign currency contracts Other current assets $ 1,066 $ 944 Foreign currency contracts Other assets 178 41 Interest rate swaps Other current assets 673 1,444 Interest rate swaps Other assets 24 322 Total assets $ 1,941 $ 2,751 Foreign currency contracts Other accrued liabilities $ 1,180 $ 1,929 Foreign currency contracts Other long-term liabilities 63 464 Total liabilities $ 1,243 $ 2,393 Our only financial instrument for which the carrying value differs from its fair value is long-term debt.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In the second quarter of 2018, we initiated restructuring actions in conjunction with exiting the wind pitch controls business within our Industrial Systems segment. These actions have resulted in workforce reductions, principally in Germany and China. The restructuring charge in 2018 consisted of $12,198 of non-cash inventory reserves, $12,316 of non-cash charges for the impairment of intangible assets, $2,162 of non-cash charges, primarily for the impairment of other long-lived assets, $7,969 for severance, $3,130 for facility closure and $3,217 for other costs. Restructuring activity for severance and other costs is as follows: Aircraft Controls Space and Defense Controls Industrial Systems Corporate Total Balance at September 29, 2018 $ 626 $ 64 $ 6,994 $ 429 $ 8,113 Adjustments to provision 20 — — — 20 Cash payments - 2016 plan — — — (297 ) (297 ) Cash payments - 2018 plan (650 ) (23 ) (2,298 ) — (2,971 ) Foreign currency translation 4 — (95 ) — (91 ) Balance at March 30, 2019 $ — $ 41 $ 4,601 $ 132 $ 4,774 As of March 30, 2019 , the restructuring accrual consists of $132 for the 2016 plan and $4,642 for the 2018 plan.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate for the three and six months ended March 30, 2019 were 23.8% and 24.1% , respectively. The effective tax rate for this period is higher than would be expected by applying the U.S. federal statutory tax rate of 21% to earnings before income taxes primarily due to tax on earnings generated outside of the U.S. The effective tax rate for the three and six months ended March 31, 2018 were 45.6% and 79.2% , respectively. The effective tax rate for this period was significantly impacted by the enactment of the Tax Cuts and Jobs Act (the "Act") of 2017. The Act was enacted on December 22, 2017. It reduced the U.S. federal corporate tax rate from 35% to 21% , required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and created new taxes on certain foreign sourced earnings. In 2018, we recorded provisional amounts by applying the guidance in SAB 118, as we had not yet completed the accounting for the tax effects of enactment of the Act. For the year ended September 29, 2018, we recorded tax expense related to the Act of $30,795 for the one-time transition tax on undistributed foreign earnings deemed to be repatriated and a tax charge of $10,383 as an additional provision for taxes on undistributed earnings not considered to be permanently reinvested. These charges were partially offset by a $10,946 benefit due to the remeasurement of deferred tax assets and liabilities arising from the lower U.S. corporate tax rate. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities is not practicable. Upon further analysis of the Act and notices and regulations issued and proposed by the U.S. Department of the Treasury and the Internal Revenue Service, we finalized our calculations of the transition tax liability with no further amounts recorded in the six months ended March 30, 2019.

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 may still be significant effort required to complete the ultimate deliverable. Future variability in internal cost 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 are contingently liable for $35,285 of standby letters of credit issued to third parties on our behalf at March 30, 2019

In the opinion of management, all adjustments consisting of normal recurring adjustments considered necessary for the fair presentation of results for the interim period have been included. The results of operations for the three and six months ended March 30, 2019 are not necessarily indicative of the results expected for the full year. The accompanying unaudited consolidated condensed financial statements should be read in conjunction with the financial statements and notes thereto included in our Form 10-K for the fiscal year ended September 29, 2018
Reclassification	Certain prior year amounts have been reclassified to conform to current year's presentation. Management does not consider the amounts reclassified to be material.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted Standard Description Financial Statement Effect or Other Significant Matters ASU no. 2014-09 Revenue from Contracts with Customers The standard requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. The provisions of the standard, as well as all subsequently issued clarifications to the standard, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The standard can be adopted using either a full retrospective or modified retrospective approach. We adopted this standard using the modified retrospective method, under which prior years' results are not restated, but supplemental information is provided in our disclosures to present 2019 results before effect of the standard. In addition, a cumulative adjustment was made to shareholders' equity at the beginning of 2019. Supplemental information is provided in our disclosures to present 2019 results before effect of the standard. Date adopted: ASU no. 2017-07 Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost The standard amends existing guidance on the presentation of net periodic benefit cost in the income statement and what qualifies for capitalization on the balance sheet. The provisions of the standard are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period. The amendment requires income statement presentation provisions to be applied retrospectively and capitalization in assets provisions to be applied prospectively. We adopted this standard retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the Consolidated Condensed Statement of Earnings. Supplemental information is provided in our disclosures to present 2018 results before effect of the standard. Date adopted: Recent Accounting Pronouncements Not Yet Adopted Standard Description Financial Statement Effect or Other Significant Matters ASU no. 2016-02 Leases (and all related ASUs) The standard requires most lease arrangements to be recognized in the balance sheet as lease assets and lease liabilities. The standard also requires additional disclosures about the leasing arrangements. The provisions of the standard are effective for fiscal years beginning after December 15, 2018 and interim periods within those years. Early adoption is permitted. We are currently evaluating the effect on our financial statements and related disclosures. Planned date of adoption: Q1 2020 ASU no. 2017-12 Targeted Improvements to Accounting for Hedging Activities The standard expands the hedging strategies eligible for hedge accounting, while simplifying presentation and disclosure by eliminating separate measurement and reporting of hedge ineffectiveness. The provisions of the standard are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effect on our financial statements and related disclosures. Planned date of adoption: Q1 2020 ASU no. 2018-15 Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract The standard amends ASC 350 to include in its scope implementation costs of a Cloud Computing Arrangement (CCA) that is a service contract and clarifies that a customer should apply ASC 350-40 to determine which implementation costs should be capitalized in a CCA that is considered a service contract. The ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The amendments should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We are currently evaluating the effect on our financial statements and related disclosures. Planned date of adoption: On September 30, 2018, we adopted ASC 606: Revenue from Contracts with Customers and the related amendments (ASC 606), using the modified retrospective method, as described above. ASC 606 was applied to contracts that were not completed as of September 29, 2018. Prior periods have not been restated and continue to be reported under the accounting standard in effect for those periods. Previously, we recognized revenue under ASC 605: Revenue Recognition (ASC 605).
