Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation The consolidated balance sheet as of December 29, 2017, the consolidated statement of operations and comprehensive income (loss) for the three-month periods ended December 29, 2017, and December 30, 2016, and the consolidated statement of cash flows for the three-month periods ended December 29, 2017, and December 30, 2016, are unaudited but, in the opinion of management, all of the necessary adjustments, consisting of normal recurring accruals, have been made to present fairly the financial statements referred to above in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the above statements do not include all of the footnotes required for complete financial statements. The results of operations and cash flows for the interim periods presented are not necessarily indicative of results that can be expected for the full year. The notes to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended September 29, 2017, provide a summary of significant accounting policies and additional financial information that should be read in conjunction with this Form 10-Q. The timing of the Company’s revenues is impacted by the purchasing patterns of customers and, as a result, revenues are not generated evenly throughout the year. Moreover, the Company’s first fiscal quarter, October through December, includes significant holiday periods in both Europe and North America, resulting in fewer business days.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recent Accounting Pronouncements	Note 2 – Recent Accounting Pronouncements In March 2017 the Financial Accounting Standards Board (FASB) issued new guidance on the presentation of the net periodic cost of postretirement benefit programs. The new standard requires sponsors of defined benefit postretirement plans to present the non-service cost components of net periodic benefit cost separate from the service cost component on the income statement. The new standard also requires that the non-service cost components of net periodic benefit cost no longer be capitalized within assets. The Company is evaluating the effects the standard will have on the Company’s consolidated financial statements and related disclosures beyond the change in income statement presentation. This new standard is effective for the Company in fiscal year 2019, with early adoption permitted. In January 2017 the FASB issued new guidance regarding the goodwill impairment test. The new guidance eliminates the Step 2 valuation test when evaluating goodwill for impairment. The new guidance requires that an entity performs its annual or interim goodwill test by comparing the fair value of the reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance is effective for the Company in fiscal year 2021, with early adoption permitted. The standard was implemented in the first quarter of fiscal 2018. In October 2016 the FASB issued new guidance regarding income taxes. The new guidance will require the tax effects of intercompany transactions, other than sales of inventory, to be recognized currently, eliminating an exception under current Generally Accepted Accounting Principles (GAAP) in which the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use. The Company is evaluating the effect the updated standard will have on the Company’s consolidated financial statements and related disclosures. The guidance will be effective for the company in fiscal year 2019, with early adoption permitted. In August 2016 the FASB issued new guidance addressing how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company is evaluating the effect the updated standard will have on the Company’s consolidated financial statements and related disclosures. The guidance will be effective for the Company in fiscal year 2019, with early adoption permitted. In June 2016 the FASB issued a new standard on the measurement of credit losses, which will impact the Company’s measurement of trade receivables. The new standard replaces the current incurred loss model with a forward-looking expected loss model that is likely to result in earlier recognition of losses. The Company is evaluating the effect the updated standard will have on the Company’s consolidated financial statements and related disclosures. The new standard is effective for the Company in 2021, with early adoption permitted, but not earlier than 2020. In February 2016 the FASB issued a new lease accounting standard, which provides revised guidance on accounting for lease arrangements by both lessors and lessees. The central requirement of the new standard is that lessees must recognize lease-related assets and liabilities for all leases with a term longer than 12 months. The Company is evaluating the effect the standard will have on the Company’s consolidated financial statements and related disclosures. The new standard is effective for the Company in fiscal year 2020, with early adoption permitted. In July 2015, the FASB issued guidance which simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This new guidance was adopted in the first quarter of fiscal 2018, with no impact to the Company’s consolidated financial statements and related disclosures. Revenue Recognition In May 2014 the FASB issued a comprehensive new revenue recognition standard that effectively replaces all current guidance on the topic. The guidance permits the use of either a retrospective or a cumulative effect transition method. The Company has performed a review of the new guidance against the Company’s current accounting practices. The Company has reviewed a representative sample of contracts and other agreements with customers and evaluated the provisions contained within these agreements compared with the amended guidance. This amended guidance is expected to change the revenue recognition practices for a number of revenue streams across our businesses; the most significant will be for certain U.S. government contracts and certain other contracts that meet one or more of the mandatory criteria, which will move revenue recognition from a “point-in-time” basis to an “over-time” basis. The on-going effect of recording revenue on an “over-time” basis is not expected to be materially different than under the historical guidance. The amended guidance is also expected to change the recognition of certain development costs that are contractually guaranteed for reimbursement by our customers. Contractually guaranteed reimbursements for development efforts are currently recognized as the development activities are performed. Under the amended guidance, the contractually guaranteed reimbursement specific to the development effort will be deferred as a contract liability and recognized as revenue when future products are delivered to the customer in cases where the Company does not transfer all intellectual property rights related to the development effort to the customer or does not have an enforceable right to payment for performance completed to date. The costs associated with development effort under an arrangement with contractually guaranteed reimbursement will also be deferred, up to the amount reimbursed, and recognized through cost of goods sold as products are delivered to the customer. The on-going effect of deferring contractually guaranteed reimbursements and the related costs until products are delivered to the customer is not expected to be materially different than under the historical guidance. The new standard also significantly enhances required disclosures regarding revenue and related assets and liabilities. The Company is in the process of implementing changes to business processes, systems and internal controls required to adopt the new accounting standard. The updated standard becomes effective for the Company in the first quarter of fiscal 2019, with early adoption permitted. The Company expects to apply the standard using the cumulative effect transition basis, with a cumulative effect adjustment recognized at the beginning of fiscal year 2019.

Earnings Per Share [Abstract]
Earnings Per Share and Shareholders Equity	Note 3 – Earnings Per Share and Shareholders’ Equity Basic earnings per share is computed on the basis of the weighted average number of shares outstanding during the year. Diluted earnings per share includes the dilutive effect of stock options, restricted stock units and share units related to the Company’s performance share plan to the extent that performance share plan objectives are met. Common shares issuable from stock options excluded from the calculation of diluted earnings per share because they were anti-dilutive were 809,875 in the three-month period ending December 30, 2016. Shares used for calculating earnings per share are disclosed in the following table: In Thousands Three Months Ended December 29, December 30, 2017 2016 Shares used for basic earnings per share 29,903 29,547 Shares used for diluted earnings per share 29,903 29,831 The authorized capital stock of the Company consists of 25,000 shares of preferred stock ($100 par value), 475,000 shares of serial preferred stock ($1.00 par value), each issuable in series, and 60,000,000 shares of common stock ($.20 par value). As of December 29, 2017, and September 29, 2017, there were no shares of preferred stock or serial preferred stock outstanding. On June 19, 2014, the Company’s Board of Directors approved a $200 million share repurchase program. In March 2015, the Company’s Board of Directors approved an additional $200 million for the share repurchase program. Under the program, the Company is authorized to repurchase up to $400 million of outstanding shares of common stock from time to time, depending on market conditions, share price and other factors. Repurchases may be made in the open market or through private transactions, in accordance with SEC requirements. The Company may enter into a Rule 10(b)5-1 plan designed to facilitate the repurchase of all or a portion of the repurchase amount. The program does not require the Company to acquire a specific number of shares. Common stock repurchased can be reissued, and accordingly, the Company accounts for repurchased stock under the cost method of accounting. During the three months ended December 29, 2017, the Company repurchased 287,500 shares under this program at an average price paid per share of $71.11, for an aggregate purchase price of $20.4 million. There were no shares repurchased during the three months ended December 30, 2016. Subsequent to December 29, 2017, we repurchased 313,900 shares under this program at an average price paid per share of $72.25, for an aggregate purchase price of $23.0 million through March 30, 2018. Since the program began, the Company has repurchased 3,737,327 shares for an aggregate purchase price of $352.0 million, with $48.0 million in shares remaining available for repurchase in the future.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5 – Fair Value Measurements 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. A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value. An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The hierarchy of fair value measurements is described below: Level 1 – Valuations are based on quoted prices that the Company has the ability to obtain in actively traded markets for identical assets and liabilities. Since valuations are based on quoted prices that are readily and regularly available in an active market or exchange traded market, a valuation of these instruments does not require a significant degree of judgment. Level 2 – Valuations are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 – Valuations are based on model-based techniques for which some or all of the assumptions are not observable and therefore obtained from indirect market information that is significant to the overall fair value measurement and which require a significant degree of management judgment. The following table sets forth the Company’s financial assets and liabilities that were measured at fair value on a recurring basis by level within the fair value hierarchy at December 29, 2017, and September 29, 2017. In Thousands Level 2 December 29, September 29, 2017 2017 Assets: Derivative contracts designated as hedging instruments $ 13,273 $ 13,932 Derivative contracts not designated as hedging instruments 893 284 Embedded derivatives 681 746 Liabilities: Derivative contracts designated as hedging instruments $ 364 $ 464 Derivative contracts not designated as hedging instruments 1,445 2,440 Embedded derivatives 1,792 2,239 In Thousands Level 3 December 29, September 29, 2017 2017 Assets: Estimated value of assets held for sale $ 16,844 $ 19,835 Liabilities: Estimated value of liabilities held for sale $ 5,189 $ 8,908 The Company’s embedded derivatives are the result of entering into sales or purchase contracts that are denominated in a currency other than the Company’s functional currency or the supplier’s or customer’s functional currency. The fair value is determined by calculating the difference between quoted exchange rates at the time the contract was entered into and the period-end exchange rate. These contracts are categorized as Level 2 in the fair value hierarchy. The Company’s derivative contracts consist of foreign currency exchange contracts and, from time to time, interest rate swap agreements. These derivative contracts are over the counter, and their fair value is determined using modeling techniques that include market inputs such as interest rates, yield curves, and currency exchange rates. These contracts are categorized as Level 2 in the fair value hierarchy. The Company’s board of directors previously approved the plan to sell certain non-core business units. Based upon the estimated fair values, the Company adjusted the carrying value of the assets and liabilities of the businesses to fair value. Principle assumptions used in measuring the estimated value of assets and liabilities held for sale included estimated selling price of the discontinued business, discount rates, industry growth rates, and pricing of comparable transactions in the market. The valuations are categorized as Level 3 in the fair value hierarchy.

Derivative Financial Instrument

Derivative Financial Instruments	3 Months Ended

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 6 – Derivative Financial Instruments The Company uses derivative financial instruments in the form of foreign currency forward exchange contracts and interest rate swap contracts for the purpose of minimizing exposure to changes in foreign currency exchange rates on business transactions and interest rates, respectively. The Company’s policy is to execute such instruments with banks the Company believes to be creditworthy and not to enter into derivative financial instruments for speculative purposes. These derivative financial instruments do not subject the Company to undue risk, as gains and losses on these instruments generally offset gains and losses on the underlying assets, liabilities, or anticipated transactions that are being hedged. All derivative financial instruments are recorded at fair value in the Consolidated Balance Sheet. For a derivative that has not been designated as an accounting hedge, the change in the fair value is recognized immediately through earnings. For a derivative that has been designated as an accounting hedge of an existing asset or liability (a fair value hedge), the change in the fair value of both the derivative and underlying asset or liability is recognized immediately through earnings. For a derivative designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the Consolidated Balance Sheet in Accumulated Other Comprehensive Income (AOCI) to the extent the derivative is effective in mitigating the exposure related to the anticipated transaction. The change in the fair value related to the ineffective portion of the hedge, if any, is immediately recognized in earnings. The amount recorded within AOCI is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings. The fair value of derivative instruments is presented on a gross basis, as the Company does not have any derivative contracts which are subject to master netting arrangements. The Company did not have any hedges with credit-risk-related contingent features or that required the posting of collateral as of December 29, 2017, and September 29, 2017. The cash flows from derivative contracts are recorded in operating activities in the Consolidated Statement of Cash Flows. Foreign Currency Forward Exchange Contracts The Company transacts business in various foreign currencies, which subjects the Company’s cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. At December 29, 2017, and September 29, 2017, the Company had outstanding foreign currency forward exchange contracts principally to sell U.S. dollars with notional amounts of $428.8 million and $406.9 million, respectively. The notional value of our foreign currency forward contracts includes $69.2 million related to the hedge of a portion of our net monetary assets, including the embedded derivatives in our backlog. These notional values consist primarily of contracts for the British pound sterling, Canadian dollar, and European euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective dates. Interest Rate Swaps The Company manages its exposure to interest rate risk by maintaining an appropriate mix of fixed and variable rate debt, which over time should moderate the costs of debt financing. When considered necessary, the Company may use financial instruments in the form of interest rate swaps to help meet this objective. Embedded Derivative Instruments The Company’s embedded derivatives are the result of entering into sales or purchase contracts that are denominated in a currency other than the Company’s functional currency or the supplier’s or customer’s functional currency. Net Investment Hedge In April 2015 the Company issued €330.0 million in 3.625% Senior Notes due April 2023 (2023 Notes) and requiring semi-annual interest payments in April and October each year until maturity. The Company designated the 2023 Notes and accrued interest as a hedge of the investment of certain foreign business units. The foreign currency gain or loss that is effective as a hedge is reported as a component of accumulated other comprehensive income (loss) in shareholders’ equity. To the extent that this hedge is ineffective, the foreign currency gain or loss is recorded in earnings. There was no ineffectiveness of the hedge since inception. Fair Value of Derivative Instruments Fair value of derivative instruments in the Consolidated Balance Sheet at December 29, 2017, and September 29, 2017, consisted of: In Thousands Fair Value December 29, September 29, Classification 2017 2017 Foreign Currency Forward Exchange Contracts: Other current assets $ 11,708 $ 11,433 Other assets 2,458 2,783 Accrued liabilities 1,653 2,506 Other liabilities 156 398 Embedded Derivative Instruments: Other current assets $ 534 $ 604 Other assets 147 142 Accrued liabilities 1,306 1,657 Other liabilities 486 582 The effect of derivative instruments on the Consolidated Statement of Operations and Comprehensive Income (Loss) for the three-month periods ended December 29, 2017, and December 30, 2016, consisted of: Fair Value Hedges and Embedded Derivatives The Company recognized the following gains (losses) on contracts designated as fair value hedges and embedded derivatives: In Thousands Three Months Ended Gain (Loss) December 29, December 30, 2017 2016 Fair Value Hedges: Recognized in cost of sales $ (378 ) $ (933 ) Recognized in selling, general & administrative (323 ) (768 ) Embedded derivatives: Recognized in sales $ 345 $ 253 Cash Flow Hedges The Company recognized the following gains (losses) on contracts designated as cash flow hedges: In Thousands Three Months Ended Gain (Loss) December 29, December 30, 2017 2016 Foreign currency forward exchange contracts: Recognized in AOCI (effective portion) $ (2,493 ) $ (2,416 ) Reclassified from AOCI into sales 1,933 (4,425 ) Net Investment Hedges The Company recognized the following gains (losses) on contracts designated as net investment hedges: In Thousands Three Months Ended Gain (Loss) December 29, December 30, 2017 2016 2023 Notes and Accrued Interest: Recognized in AOCI $ (6,297 ) $ 23,913 During the first quarter of fiscal 2018 and 2017, the Company recorded a gain of $1.5 million and a loss of $0.9 million, respectively, on foreign currency forward exchange contracts that have not been designated as accounting hedges. These foreign currency exchange gains and losses are included in selling, general and administrative expense. There was no significant impact to the Company’s earnings related to the ineffective portion of any hedging instruments during the first quarter of fiscal 2018 and 2017. In addition, there was no significant impact to the Company’s earnings when a hedged firm commitment no longer qualified as a fair value hedge or when a hedged forecasted transaction no longer qualified as a cash flow hedge during the first quarter of fiscal 2018 and 2017. Amounts included in AOCI are reclassified into earnings when the hedged transaction settles. The Company expects to reclassify approximately $10.9 million of net gain into earnings over the next 12 months. The maximum duration of the Company’s foreign currency cash flow hedge contracts at December 29, 2017, was 24 months.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 9 – Income Taxes The Tax Cuts and Jobs Act (the Act) was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The SEC recognized that a company’s review of certain income tax effects of the Act may be incomplete at the time financial statements are issued. Accordingly, the SEC issued Staff Accounting Bulletin 118, which provides that if a company does not have the necessary information available for certain effects of the Act, the Company may record provisional numbers and adjust those amounts during the measurement period not to extend beyond one year. At December 29, 2017, the Company had not completed the accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, the Company made a reasonable estimate of the effects on its existing deferred tax balances and the one-time transition tax. In other cases, the Company was not able to make a reasonable estimate and continued to account for those items based on its existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment. For the items for which the Company was able to determine a reasonable estimate, the Company recognized a provisional amount of $48.6 million, which is included as a component of income tax expense from continuing operations. In all cases, the Company will continue to make and refine the calculations as additional analysis is completed. In addition, the estimates may also be affected as the Company gains a more thorough understanding of the tax law. Provisional Amounts U.S. Deferred Tax Assets and Liabilities The Company remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, the Company is still analyzing certain aspects of the Act and refining its calculations, including evaluation of limits on employee remuneration, which could affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount recorded related to the remeasurement of the deferred tax balance was $6.6 million. Foreign Tax Effects The one-time transition tax is based on the Company’s total post-1986 earnings and profits (E&P) that the Company previously deferred from U.S. income taxes. The Company recorded a provisional amount for its one-time transition tax liability resulting in an increase in income tax expense of $42.0 million. The Company is still analyzing certain aspects of the Act and refining its calculations, which could potentially affect the measurement of these amounts, including the benefit attributable to foreign tax credits and related elections. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when the Company finalizes the calculations of post-1986 foreign E&P previously deferred from U.S. taxation and finalizes the amounts of cash or other specified assets. The Act sets certain limits that may restrict the Company’s use of any foreign tax credits generated from the one-time transaction tax. As of the date of this report, management was not able to (1) determine a reasonable estimate of the tax liability for the Company’s remaining outside basis; (2) complete an analysis of the Global Intangible Low Taxed Income (GILTI); (3) determine the accounting for GILTI because ASC 740 is not clear whether GILTI will require the recording of deferred income tax expense; and (4) evaluate how the Act will impact the Company’s existing APB 23 position to indefinitely reinvest unremitted foreign earnings. This could result in a material adjustment to the provisional income tax expense recorded in the first quarter of fiscal 2018. The income tax rate for the first quarter of fiscal 2018 was 26.9% before the effect of the provisional taxes due to the Act and was 278.3% after the effect of the provisional taxes due to the Act. The prior-year period was a benefit of 2.2%. The Company conducts business in numerous tax jurisdictions, principally in the U.S., Canada, U.K. and France. As a result, the Company’s income tax rate for the first fiscal quarter of 2018 reflects the estimated annual global effective tax rate, excluding discrete items, applied to year-to-date pre-tax earnings. The following table summarizes the income tax rate for the first quarter of fiscal 2018 excluding and including the provisional taxes due to the Act. In Thousands Three Months Ended December 29, 2017 Excluding Including Earnings from Continuing Operations Before Income Taxes $ 19,327 $ 19,327 Income Tax Expense 5,573 5,573 Change in Tax Rate Due to the Act (368 ) (368 ) Provisional Taxes Due to the Act - 48,584 Total Income Tax Expense 5,205 53,789 Tax Rate 26.9 % 278.3 % The income tax rate for the first quarter of fiscal 2018 reflected a blended U.S. tax rate of 24.5%, which is based upon an income tax rate of 35% for the Company’s first quarter of fiscal 2018 and 21% for the balance of the year ending September 28, 2018. The 2.2% income tax rate in the first quarter of fiscal 2017 reflected the following items: First, a reduction of the income tax rate in France for fiscal year 2020, which resulted in a reduction in the Company’s net deferred income tax liabilities of $3.8 million. Second, $1.6 million of discrete tax benefits was recorded, primarily related to a valuation allowance release due to an expected taxable gain from a foreign income tax law change. Third, the early adoption of the accounting standard update for employee share-based payment awards resulted in a $0.7 million tax benefit. By the end of fiscal 2018, it is reasonably possible that approximately $1.4 million of tax benefits that are currently unrecognized could be recognized as a result of settlement of examinations and/or the expiration of applicable statutes of limitations. The Company recognizes interest related to unrecognized tax benefits in income tax expense.

The Company recorded $2.3 million in debt issuance costs. The credit facility is secured by substantially all the Company’s assets, and interest is based on standard inter-bank offering rates. The interest rate ranges from LIBOR plus 1.25% to LIBOR plus 2.00% depending on leverage ratios at the time the funds are drawn. At December 29, 2017, the Company had $70.0 million outstanding under the secured credit facility at an interest rate of LIBOR plus 1.50%, which was 2.82%. On February 13, 2018, the Company obtained a waiver and consent from the required lenders under the Company’s U.S. credit facilities of the financial reporting breaches resulting from the Restatement described in Note 2 of Company’s fiscal 2017 Form 10-K/A. U.S. Term Loan, due April 2020 On August 3, 2015, the Company borrowed $250 million under the amended secured credit facility (U.S. Term Loan, due 2020). The interest rate on the U.S. Term Loan, due 2020, ranges from LIBOR plus 1.25% to LIBOR plus 2.00%. At December 29, 2017, the interest rate was LIBOR plus 1.50%, or 2.85%. The loan amortizes at 1.25% of the original principal balance quarterly through March 2020, with the remaining balance due in April 2020. 3.625% Senior Notes, due April 2023 In April 2015 TA Mfg. Limited, a wholly owned subsidiary of the Company, issued €330.0 million in 3.625% Notes, due 2023 requiring semi-annual interest payments in April and October of each year until maturity. The net proceeds from the sale of the notes, after deducting $5.9 million of debt issuance costs, were $350.8 million. The 2023 Notes are general unsecured senior obligations of the Company. The 2023 Notes are unconditionally guaranteed on a senior basis by the Company and certain subsidiaries of the Company that are guarantors under the Company’s existing secured credit facility. The 2023 Notes are subject to redemption at the option of the Company at any time prior to April 15, 2018, at a price equal to 100% of the principal amount, plus any accrued interest to the date of redemption and a make-whole provision. The Company may also redeem up to 35% of the 2023 Notes before April 15, 2018, with the net cash proceeds from equity offerings. The 2023 Notes are also subject to redemption at the option of the Company, in whole or in part, on or after April 15, 2018, at redemption prices starting at 102.719% of the principal amount plus accrued interest during the period beginning April 15, 2018, and declining annually to 100% of principal and accrued interest on or after April 15, 2021. Based on quoted market prices, the fair value of the Company’s 2023 Notes was $406.1 million and $403.2 million as of December 29, 2017, and September 29, 2017, respectively. The carrying amount of the secured credit facility and the U.S. Term Loan, due 2020, approximate fair value. The estimate of fair value for the 2023 Notes is based on Level 2 inputs as defined in the fair value hierarchy described in Note 5. Government Refundable Advances Government refundable advances consist of payments received from the Canadian government to assist in research and development related to commercial aviation. The requirement to repay this advance is solely based on year-over-year commercial aviation revenue growth at CMC beginning in 2014. Imputed interest on the advance was 2.52% at December 29, 2017. The debt recognized was $45.5 million at December 29, 2017, and September 29, 2017. Obligation Under Capital Lease The Company leases building and equipment under capital leases.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Employee Stock Plans	Note 12 – Employee Stock Plans As of December 29, 2017, the Company had three share-based compensation plans, which are described below. The compensation cost that has been charged against income for those plans was $4.0 million and $4.2 million for the first three months of fiscal 2018 and 2017, respectively. During the first three months of fiscal 2018 and 2017, the Company issued 27,693 and 237,547 shares, respectively, under its share-based compensation plans. Employee Stock Purchase Plan (ESPP) The ESPP is a “safe-harbor” designed plan whereby shares are purchased by participants at a discount of 5% of the market value on the purchase date and, therefore, compensation cost is not recorded. Employee Sharesave Scheme The Company offers shares under its employee sharesave scheme for U.K. employees. This plan allows participants the option to purchase shares at a 5% discount of the market price of the stock as of the beginning of the offering period. The term of these options is three years. The sharesave scheme is not a “safe-harbor” design, and therefore, compensation cost is recognized on this plan. Under the sharesave scheme, option exercise prices are equal to the fair market value of the Company’s common stock on the date of grant. There were no grants in the three-month periods ended December 29, 2017, and December 30, 2016. Equity Incentive Plan Under the equity incentive plan, option exercise prices are equal to the fair market value of the Company’s common stock on the date of grant. The Company granted 197,700 and 231,100 options to purchase shares in the three-month periods ended December 29, 2017, and December 30, 2016, respectively. The weighted-average grant date fair value of options granted during the three-month periods ended December 29, 2017, and December 30, 2016, was $31.20 and $32.55 per share, respectively. The fair value of each option granted by the Company was estimated using a Black-Scholes pricing model, which uses the assumptions noted in the following table. The Company uses historical data to estimate volatility of the Company’s common stock and option exercise and employee termination assumptions. The risk-free rate for the contractual life of the option is based on the U.S. Treasury zero coupon issues in effect at the time of the grant.

The weighted-average grant date fair value of restricted stock units granted during the three-month periods ended December 29, 2017, and December 30, 2016, was $91.79 and $76.70 per share, respectively. The fair value of each restricted stock unit granted by the Company is equal to the fair market value of the Company’s common stock on the date of grant. The Company granted 33,700 and 42,100 performance share plan (PSP) shares in the three-month periods ended December 29, 2017, and December 30, 2016, respectively. PSP shares will be paid out in shares of Esterline common stock at the end of the three year performance period. The PSP shares granted in each period equaled the number of shares participants would receive if the Company achieves target performance over the relevant period. The actual number of shares that will be paid out upon completion of the performance period is based on actual performance and may range from 0% to 300% of the target number of shares.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	Note 13 – Discontinued Operations The Company’s Board of Directors previously approved the plan to sell certain non-core business units including Wallop Defence Systems, Ltd. (Wallop), a manufacturer of flare countermeasure devices; a small distribution business; and a small manufacturing business. On May 4, 2016, the Company sold certain assets of Wallop for 2.5 million British pounds and deferred consideration up to a maximum payment of 9 million British pounds. In the definitive purchase and sale agreement for the sale of these assets, the Company provided standard representations and warranties as well as indemnification to the buyer of the Wallop operation. The Company is obligated to indemnify the buyer for certain losses of up to 5.0 million British pounds, if, among other things, the Company breaches the representations and warranties. In the first quarter of fiscal 2018, the Company received notification of a claim from the buyer of the Wallop operation alleging breaches of representations and warranties primarily associated with defective products and late product deliveries. Although a loss is possible, the amount of any loss related to this claim cannot be estimated at this time. The Company does not expect the possible loss to have a material effect on the Company’s financial position. The deferred consideration is payable based upon receipt of acceptable orders during a three-year period ending May 3, 2019, and is equal to the amount of the acceptable order times a specified percentage ranging from 26.5% to 31%. The earn-out payment is estimated to be 4.1 million British pounds, or $5.5 million, at December 29, 2017. In December 2017 the buyer notified the Company that 1.3 million British pounds, or $1.8 million, of deferred consideration had been earned. On March 28, 2017, the Company sold a small manufacturing business for $0.6 million and a note receivable of $2.4 million, resulting in a gain on sale of the business of $0.8 million. The note receivable is due March 28, 2021, with an interest rate of 2.05%. The Company incurred a $0.2 million loss from discontinued operations in the first quarter of fiscal 2018 compared to a $5.3 million loss from discontinued operations in the first quarter of fiscal 2017.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Recent Accounting Pronouncements	In March 2017 the Financial Accounting Standards Board (FASB) issued new guidance on the presentation of the net periodic cost of postretirement benefit programs. The new standard requires sponsors of defined benefit postretirement plans to present the non-service cost components of net periodic benefit cost separate from the service cost component on the income statement. The new standard also requires that the non-service cost components of net periodic benefit cost no longer be capitalized within assets. The Company is evaluating the effects the standard will have on the Company’s consolidated financial statements and related disclosures beyond the change in income statement presentation. This new standard is effective for the Company in fiscal year 2019, with early adoption permitted. In January 2017 the FASB issued new guidance regarding the goodwill impairment test. The new guidance eliminates the Step 2 valuation test when evaluating goodwill for impairment. The new guidance requires that an entity performs its annual or interim goodwill test by comparing the fair value of the reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance is effective for the Company in fiscal year 2021, with early adoption permitted. The standard was implemented in the first quarter of fiscal 2018. In October 2016 the FASB issued new guidance regarding income taxes. The new guidance will require the tax effects of intercompany transactions, other than sales of inventory, to be recognized currently, eliminating an exception under current Generally Accepted Accounting Principles (GAAP) in which the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use. The Company is evaluating the effect the updated standard will have on the Company’s consolidated financial statements and related disclosures. The guidance will be effective for the company in fiscal year 2019, with early adoption permitted. In August 2016 the FASB issued new guidance addressing how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company is evaluating the effect the updated standard will have on the Company’s consolidated financial statements and related disclosures. The guidance will be effective for the Company in fiscal year 2019, with early adoption permitted. In June 2016 the FASB issued a new standard on the measurement of credit losses, which will impact the Company’s measurement of trade receivables. The new standard replaces the current incurred loss model with a forward-looking expected loss model that is likely to result in earlier recognition of losses. The Company is evaluating the effect the updated standard will have on the Company’s consolidated financial statements and related disclosures. The new standard is effective for the Company in 2021, with early adoption permitted, but not earlier than 2020. In February 2016 the FASB issued a new lease accounting standard, which provides revised guidance on accounting for lease arrangements by both lessors and lessees. The central requirement of the new standard is that lessees must recognize lease-related assets and liabilities for all leases with a term longer than 12 months. The Company is evaluating the effect the standard will have on the Company’s consolidated financial statements and related disclosures. The new standard is effective for the Company in fiscal year 2020, with early adoption permitted. In July 2015, the FASB issued guidance which simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This new guidance was adopted in the first quarter of fiscal 2018, with no impact to the Company’s consolidated financial statements and related disclosures. Revenue Recognition In May 2014 the FASB issued a comprehensive new revenue recognition standard that effectively replaces all current guidance on the topic. The guidance permits the use of either a retrospective or a cumulative effect transition method. The Company has performed a review of the new guidance against the Company’s current accounting practices. The Company has reviewed a representative sample of contracts and other agreements with customers and evaluated the provisions contained within these agreements compared with the amended guidance. This amended guidance is expected to change the revenue recognition practices for a number of revenue streams across our businesses; the most significant will be for certain U.S. government contracts and certain other contracts that meet one or more of the mandatory criteria, which will move revenue recognition from a “point-in-time” basis to an “over-time” basis. The on-going effect of recording revenue on an “over-time” basis is not expected to be materially different than under the historical guidance. The amended guidance is also expected to change the recognition of certain development costs that are contractually guaranteed for reimbursement by our customers. Contractually guaranteed reimbursements for development efforts are currently recognized as the development activities are performed. Under the amended guidance, the contractually guaranteed reimbursement specific to the development effort will be deferred as a contract liability and recognized as revenue when future products are delivered to the customer in cases where the Company does not transfer all intellectual property rights related to the development effort to the customer or does not have an enforceable right to payment for performance completed to date. The costs associated with development effort under an arrangement with contractually guaranteed reimbursement will also be deferred, up to the amount reimbursed, and recognized through cost of goods sold as products are delivered to the customer. The on-going effect of deferring contractually guaranteed reimbursements and the related costs until products are delivered to the customer is not expected to be materially different than under the historical guidance. The new standard also significantly enhances required disclosures regarding revenue and related assets and liabilities. The Company is in the process of implementing changes to business processes, systems and internal controls required to adopt the new accounting standard. The updated standard becomes effective for the Company in the first quarter of fiscal 2019, with early adoption permitted. The Company expects to apply the standard using the cumulative effect transition basis, with a cumulative effect adjustment recognized at the beginning of fiscal year 2019.
