Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Management Estimates and Uncertainties. The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements relate to allowances for accounts receivable; provisions for excess and obsolete inventories, product returns, warranties, environmental matters, and legal exposures; determining the recoverability of claims made in connection with customer bankruptcies; determining liabilities for uncertain tax positions; determining the realizability of deferred tax assets; determining fair values of tangible and intangible assets for purposes of business combinations and impairment tests; determining fair values of contingent consideration and equity awards; and determining forfeiture rates for purposes of calculating stock compensation expense. Actual results could differ materially from these estimates. Financial Instruments and Concentration of Credit Risk. Financial instruments consist primarily of cash and cash equivalents, accounts receivable, foreign currency forward contracts, interest rate swap agreement, accounts payable and debt obligations. With the exception of certain of the Company's debt obligations (refer to Note 5. Financial Instruments), the fair value of these financial instruments approximates their carrying amount as of September 28, 2019 and September 29, 2018 due to the nature or short maturity of these instruments, or the fact that the instruments are recorded at fair value on the consolidated balance sheets. Accounts Receivable and Other Related Allowances. The Company had an allowance of $12 million as of September 28, 2019 and September 29, 2018 for uncollectible accounts, product returns and other net sales adjustments. One of the Company's most significant risks is the ultimate realization of its accounts receivable. This risk is mitigated by ongoing credit evaluations of customers and frequent contact with customers, especially the most significant customers, which enable the Company to monitor changes in its customers' business operations and respond accordingly. To establish the allowance for doubtful accounts, the Company estimates credit risk associated with accounts receivable by considering the creditworthiness of its customers, past experience, specific facts and circumstances, and the overall economic climate in industries that it serves. To establish the allowance for product returns and other adjustments, the Company primarily utilizes historical data. Accounts Receivable Sales. During 2018, the Company entered into a Receivables Purchase Agreement (the “RPA”) with certain third-party banking institutions for the sale of trade receivables generated from sales to certain customers, subject to acceptance by the banks that are party to the RPA. Trade receivables sold pursuant to the RPA are serviced by the Company. In addition to the RPA, the Company has the option to participate in trade receivables sales programs that have been implemented by certain of the Company's customers, as in effect from time to time. The Company does not service trade receivables sold under these other programs. Under each of the programs noted above, the Company sells its entire interest in a trade receivable for 100% of face value, less a discount. Accounts receivable balances sold are removed from the consolidated balance sheets and the related proceeds are reported as cash provided by operating activities in the consolidated statements of cash flows. Inventories. Inventories are stated at the lower of cost (first-in, first-out method) and net realizable value. Cost includes labor, materials and manufacturing overhead. Provisions are made to reduce excess and obsolete inventories to their estimated net realizable values. The ultimate realization of inventory carrying amounts is primarily affected by changes in customer demand. Inventory provisions are established based on forecasted demand, past experience with specific customers, the age and nature of the inventory, the ability to redistribute inventory to other programs or back to suppliers, and whether customers are contractually obligated and have the ability to pay for the related inventory. Certain payments received from customers for inventory held by the Company are recorded as a reduction of inventory. Long-lived Assets. Property, plant and equipment are stated at cost or, in the case of property and equipment acquired through business combinations, at fair value as of the acquisition date. Depreciation is provided on a straight-line basis over 20 to 40 years for buildings and 3 to 15 years for machinery, equipment, furniture and fixtures. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or useful life of the asset. The Company reviews property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. An asset group is the unit of accounting which represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets. An asset or asset group is considered impaired if its carrying amount exceeds the undiscounted future net cash flows the asset or asset group is expected to generate. If an asset or asset group is considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value. For asset groups for which the primary asset is a building, the Company estimates fair value based on data provided by commercial real estate brokers. For other asset groups, the Company estimates fair value based on projected discounted future net cash flows. Goodwill. Goodwill is tested for impairment on an annual basis and whenever events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable, as assessed at a reporting unit level. If, based on a qualitative assessment, the Company determines it is more-likely-than-not that goodwill is impaired, the Company performs a quantitative assessment to determine whether the fair value of our reporting unit is less than its carrying value and, if so, an impairment adjustment must be recorded up to the carrying value of goodwill. Foreign Currency Translation. For foreign subsidiaries using the local currency as their functional currency, assets and liabilities are translated to U.S. dollars at exchange rates in effect at the balance sheet date and income and expenses are translated at average exchange rates. The effects of these translation adjustments are reported in stockholders' equity as a component of accumulated other comprehensive income ("AOCI"). For all entities, remeasurement adjustments for non-functional currency monetary assets and liabilities are included in other income, net in the accompanying consolidated statements of operations. Remeasurement gains and losses arising from long-term intercompany loans denominated in a currency other than an entity's functional currency are recorded in AOCI if repayment of the loan is not anticipated in the foreseeable future. Derivative Instruments and Hedging Activities. The Company conducts business on a global basis in numerous currencies and certain of the Company's outstanding debt has a variable interest rate. Therefore, the Company is exposed to movements in foreign currency exchange rates and interest rates. The Company uses derivatives, such as foreign currency forward contracts and interest rate swaps, to minimize the volatility of earnings and cash flows associated with changes in foreign currency exchange rates and interest rates. The Company accounts for derivative instruments and hedging activities in accordance with ASC Topic 815, Derivatives and Hedging, which requires each derivative instrument to be recorded on the consolidated balance sheets at its fair value as either an asset or a liability. If a derivative is designated as a cash flow hedge, the effective portion of changes in the fair value of the derivative is recorded in stockholders' equity as a separate component of AOCI and is recognized in earnings when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are immediately recognized in earnings. If a derivative is designated as a fair value hedge, changes in the fair value of the derivative and of the item being hedged are recognized in earnings in the current period. Derivative instruments are entered into for periods of time consistent with the related underlying exposures and are not entered into for speculative purposes. At the inception of a hedge, the Company documents all relationships between derivative instruments and related hedged items, as well as its risk-management objectives and strategies for the hedging transaction. The Company's foreign currency forward contracts and interest rate swaps potentially expose the Company to credit risk to the extent the counterparties may be unable to meet the terms of the agreement. The Company minimizes such risk by seeking high quality counterparties. Revenue Recognition. The Company derives revenue principally from sales of integrated manufacturing solutions, components and Company-proprietary products. Other sources of revenue include logistics and repair services; design, development and engineering services; defense and aerospace programs; and sales of raw materials to customers whose requirements change after the Company has procured inventory to fulfill the customer’s forecasted demand. For purposes of determining when to recognize revenue, and in what amount, the Company applies a 5-step model: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the Company satisfies a performance obligation. Each of these steps involves the use of significant judgments. The Company recognizes revenue for the majority of its contracts on an over time basis. This is due to the fact that 1) the Company does not have an alternative use for the end products it manufactures for its customers and has an enforceable right to payment, including a reasonable profit, for work-in-progress upon a customer’s cancelation of a contract for convenience or 2) the Company’s customer simultaneously receives and consumes the benefits provided by the Company’s services. For these contracts, revenue is recognized on an over time basis using the cost-to-cost method (ratio of costs incurred to date to total estimated costs at completion) which the Company believes best depicts the transfer of control to the customer. Revenue streams for which revenue is recognized on an over time basis include sales of vertically integrated manufacturing solutions (integrated manufacturing solutions and components); logistics and repair services; design, development and engineering services; and defense and aerospace programs. For contracts for which revenue is required to be recognized at a point-in-time, the Company recognizes revenue when it has transferred control of the related goods, which generally occurs upon shipment or delivery of the goods to the customer. Revenue streams for which revenue is recognized at a point-in-time include Company-proprietary products and sales of raw materials. Refer to Note 4 for further discussion. Income taxes. The Company estimates its income tax provision or benefit in each of the jurisdictions in which it operates, including estimating exposures and making judgments regarding the realizability of deferred tax assets. The carrying value of the Company's net deferred tax assets is based on the Company's belief that it is more likely than not that the Company will generate sufficient future taxable income in certain jurisdictions to realize these deferred tax assets. A valuation allowance has been established for deferred tax assets which do not meet the “more likely than not” criteria discussed above. The Company's tax rate is highly dependent upon the geographic distribution of its worldwide income or losses, the tax regulations and tax holidays in each geographic region, the availability of tax credits and carryforwards, including net operating losses, and the effectiveness of its tax planning strategies. The Company makes an assessment of whether each income tax position is “more likely than not” of being sustained on audit, including resolution of related appeals or litigation, if any. For each income tax position that meets the “more likely than not” recognition threshold, the Company then assesses the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with the tax authority. Interest and penalties related to unrecognized tax benefits are recognized as a component of income tax expense. Recent Accounting Pronouncements Adopted in Fiscal Year 2019 In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefits (Topic 715)". This ASU requires the service costs component of net periodic pension costs to be presented in the same line item as other compensation costs and all other components of net periodic pension costs to be presented in the income statement as non-operating expenses. This ASU was effective for the Company at the beginning of fiscal 2019. The impact of adoption was insignificant. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805)". This ASU provides guidance to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This new standard was effective for the Company at the beginning of fiscal 2019. There was no impact upon adoption of this new standard. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230)". This ASU requires that the statement of cash flows explains the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Companies will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. This ASU was effective for the Company at the beginning of fiscal 2019, including interim periods within that annual period. There was no impact upon adoption of this new standard. In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory (Topic 740)". This ASU simplifies the accounting for income tax consequences of intra-entity transfers of assets other than inventory by requiring recognition of current and deferred income tax consequences when such transfers occur. The new standard was effective for the Company at the beginning of fiscal 2019. There was no impact upon adoption of this new standard. In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" (commonly referred to as ASC 606) which requires an entity to recognize revenue when (or as) goods are transferred or services are provided to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services. The Company adopted ASC 606 as of the beginning of its first quarter of 2019 using the modified retrospective approach, whereby the cumulative effect of initially applying the guidance was recognized as an adjustment to beginning retained earnings at the date of adoption. This adjustment resulted in an increase to beginning retained earnings of $28 million. The adoption of ASC 606 resulted in a change to the manner in which the Company recognizes revenue for the majority of its revenue streams, including integrated manufacturing solutions, components, repair services and defense and aerospace programs. Prior to the adoption of ASC 606, the Company generally recognized revenue from its integrated manufacturing solutions, the Company’s largest revenue stream, upon shipment or delivery of a product to a customer. Under ASC 606, because the Company has no alternative use for the end products generated by its vertically integrated manufacturing services and has an enforceable right to payment for work-in-progress upon a customer’s cancellation of a contract for convenience, the Company recognizes revenue from the sale of these products on an over time basis as the products are manufactured. Accordingly, the Company will recognize revenue under these contracts earlier than under the previous accounting rules. Additionally, prior to the adoption of ASC 606, revenue from repair services was generally recognized upon completion of the services. Under ASC 606, revenue for these services will be recognized as the services are performed since the Company’s customers simultaneously receive and consume the benefits provided by these services. Lastly, prior to the adoption of ASC 606, revenue from defense and aerospace programs was recognized on a percentage-of-completion basis by applying the units-of-delivery method. Under ASC 606, revenue for the majority of these programs will be recognized on an over time basis using the cost-to-cost method since the Company has no alternative use for the end products manufactured under these programs and has an enforceable right to payment for work-in-progress upon a customer’s cancellation of a contract for convenience. Revenue for certain other programs will be recognized upon shipment or delivery of a product, which is when control of a product transfers to a customer. The timing of recognition of revenue did not change for some of the Company’s revenue streams as a result of the adoption of ASC 606. These revenue streams include logistics services, for which revenue will continue to be recognized as the services are performed, Company proprietary products, for which revenue will continue to be recognized upon shipment or delivery of the product, and design, development and engineering services for which revenue will continue to be recognized as the services are performed. For revenue streams for which revenue is being recognized on an over time basis under ASC 606, work-in-progress and finished goods inventory were reduced to zero upon the adoption of ASC 606 and an associated contract asset was recorded to reflect amounts that would have been recognized as revenue prior to the adoption of ASC 606. This adjustment resulted in recognition of a contract asset of $376 million and a decrease in inventory of $350 million as of the beginning of the first fiscal quarter of 2019. No other balance sheet line items, with the exception of beginning retained earnings as mentioned previously, were materially impacted upon the adoption of ASC 606. Refer to Note 4 for additional information and disclosures related to the adoption of ASC 606. Recent Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU 2018-15, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU is effective for the Company at the beginning of fiscal 2021, including interim periods within that reporting period, although early adoption is permitted. The Company does not expect the impact of adoption to be significant. In June 2018, the FASB issued ASU 2018-07 "Improvements to Non-employee Share-Based Payment Accounting (Topic 718)". The ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. The standard aligns measurement and classification guidance for share-based payments to non-employees with the guidance applicable to employees. This ASU is effective for the Company at the beginning of fiscal 2020, including interim periods within that reporting period. The Company does not expect the impact of adoption to be significant. In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which allows companies to reclassify stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (H.R. 1) from accumulated other comprehensive income to retained earnings. The guidance also requires certain new disclosures regardless of the election. This ASU is effective for the Company at the beginning of fiscal 2020. The Company does not expect the impact of adoption to be significant. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements for Accounting For Hedging Activities", simplifying hedge accounting guidance and improving the financial reporting of hedging relationships by allowing an entity to better align its risk management activities and financial reporting for hedging relationships through changes to both designation and measurement for qualifying hedging relationships and the presentation of hedge results. This standard eliminates the requirement to separately measure and report hedge ineffectiveness, resulting in full recognition of the change in fair value that impacts earnings in the same income statement line item that is used to present the earnings effect of the hedged item. In addition, the guidance allows more flexibility in the requirements to qualify for and maintain hedge accounting. This ASU is effective for the Company at the beginning of fiscal 2020. The Company does not expect the impact of adoption to be significant. In June 2016, the FASB issued ASU 2016-13 "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", which replaces the existing incurred loss impairment methodology with an expected credit loss methodology and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This new standard is effective for the Company at the beginning of fiscal 2021, including interim periods within that reporting period. The Company is currently evaluating the impact of adopting this new accounting standard. In February 2016, the FASB issued ASU 2016-02, "Leases: Amendments to the FASB Accounting Standards Codification (Topic 842)". This ASU requires the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with terms of more than twelve months. This ASU also requires disclosures enabling the users of financial statements to understand the amount, timing and uncertainty of cash flows arising from leases. The new standard is effective for the Company at the beginning of fiscal 2020, including interim periods within that reporting period. In addition, the FASB provided a practical expedient transition method that allows entities to initially apply the requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, as opposed to applying the requirements retrospectively and providing comparative prior period financial statements. The Company has decided to apply the above practical expedient transition method. The Company adopted the new standard on September 29, 2019, the first day of fiscal 2020. The Company elected certain other transition options which, among other things, allowed the Company to carry forward its prior conclusions about lease identification and classification. The Company expects adoption of the standard to result in recognition in the consolidated balance sheet of lease liabilities and right-to-use lease assets of approximately $55 million to $65 million as of September 29, 2019, based on the present value of committed lease payments. The adoption of the new standard is not expected to impact retained earnings or to have a material impact on the recognition, measurement or presentation of lease expenses within the consolidated statements of operations, consolidated statements of comprehensive income (loss) or consolidated statements of cash flows.

Management Estimates and Uncertainties. The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates made in preparing the consolidated financial statements relate to allowances for accounts receivable; provisions for excess and obsolete inventories, product returns, warranties, environmental matters, and legal exposures; determining the recoverability of claims made in connection with customer bankruptcies; determining liabilities for uncertain tax positions; determining the realizability of deferred tax assets; determining fair values of tangible and intangible assets for purposes of business combinations and impairment tests; determining fair values of contingent consideration and equity awards; and determining forfeiture rates for purposes of calculating stock compensation expense. Actual results could differ materially from these estimates.

Financial Instruments and Concentration of Credit Risk. Financial instruments consist primarily of cash and cash equivalents, accounts receivable, foreign currency forward contracts, interest rate swap agreement, accounts payable and debt obligations. With the exception of certain of the Company's debt obligations (refer to Note 5. Financial Instruments), the fair value of these financial instruments approximates their carrying amount as of September 28, 2019 and September 29, 2018 due to the nature or short maturity of these instruments, or the fact that the instruments are recorded at fair value on the consolidated balance sheets.

the Company's most significant risks is the ultimate realization of its accounts receivable. This risk is mitigated by ongoing credit evaluations of customers and frequent contact with customers, especially the most significant customers, which enable the Company to monitor changes in its customers' business operations and respond accordingly. To establish the allowance for doubtful accounts, the Company estimates credit risk associated with accounts receivable by considering the creditworthiness of its customers, past experience, specific facts and circumstances, and the overall economic climate in industries that it serves. To establish the allowance for product returns and other adjustments, the Company primarily utilizes historical data.

Accounts Receivable Sales. During 2018, the Company entered into a Receivables Purchase Agreement (the “RPA”) with certain third-party banking institutions for the sale of trade receivables generated from sales to certain customers, subject to acceptance by the banks that are party to the RPA. Trade receivables sold pursuant to the RPA are serviced by the Company.

In addition to the RPA, the Company has the option to participate in trade receivables sales programs that have been implemented by certain of the Company's customers, as in effect from time to time. The Company does not service trade receivables sold under these other programs. Under each of the programs noted above, the Company sells its entire interest in a trade receivable for 100% of face value, less a discount. Accounts receivable balances sold are removed from the consolidated balance sheets and the related proceeds are reported as cash provided by operating activities in the consolidated statements of cash flows.

Provisions are made to reduce excess and obsolete inventories to their estimated net realizable values. The ultimate realization of inventory carrying amounts is primarily affected by changes in customer demand. Inventory provisions are established based on forecasted demand, past experience with specific customers, the age and nature of the inventory, the ability to redistribute inventory to other programs or back to suppliers, and whether customers are contractually obligated and have the ability to pay for the related inventory. Certain payments received from customers for inventory held by the Company are recorded as a reduction of inventory.

Long-lived Assets. Property, plant and equipment are stated at cost or, in the case of property and equipment acquired through business combinations, at fair value as of the acquisition date. Depreciation is provided on a straight-line basis over 20 to 40 years for buildings and 3 to 15 years for machinery, equipment, furniture and fixtures. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease term or useful life of the asset.

The Company reviews property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. An asset group is the unit of accounting which represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets. An asset or asset group is considered impaired if its carrying amount exceeds the undiscounted future net cash flows the asset or asset group is expected to generate. If an asset or asset group is considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value. For asset groups for which the primary asset is a building, the Company estimates fair value based on data provided by commercial real estate brokers. For other asset groups, the Company estimates fair value based on projected discounted future net cash flows.

Goodwill. Goodwill is tested for impairment on an annual basis and whenever events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable, as assessed at a reporting unit level. If, based on a qualitative assessment, the Company determines it is more-likely-than-not that goodwill is impaired, the Company performs a quantitative assessment to determine whether the fair value of our reporting unit is less than its carrying value and, if so, an impairment adjustment must be recorded up to the carrying value of goodwill.

Foreign Currency Translation. For foreign subsidiaries using the local currency as their functional currency, assets and liabilities are translated to U.S. dollars at exchange rates in effect at the balance sheet date and income and expenses are translated at average exchange rates. The effects of these translation adjustments are reported in stockholders' equity as a component of accumulated other comprehensive income ("AOCI"). For all entities, remeasurement adjustments for non-functional currency monetary assets and liabilities are included in other income, net in the accompanying consolidated statements of operations. Remeasurement gains and losses arising from long-term intercompany loans denominated in a currency other than an entity's functional currency are recorded in AOCI if repayment of the loan is not anticipated in the foreseeable future.

movements in foreign currency exchange rates and interest rates. The Company uses derivatives, such as foreign currency forward contracts and interest rate swaps, to minimize the volatility of earnings and cash flows associated with changes in foreign currency exchange rates and interest rates.

The Company accounts for derivative instruments and hedging activities in accordance with ASC Topic 815, Derivatives and Hedging, which requires each derivative instrument to be recorded on the consolidated balance sheets at its fair value as either an asset or a liability. If a derivative is designated as a cash flow hedge, the effective portion of changes in the fair value of the derivative is recorded in stockholders' equity as a separate component of AOCI and is recognized in earnings when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are immediately recognized in earnings. If a derivative is designated as a fair value hedge, changes in the fair value of the derivative and of the item being hedged are recognized in earnings in the current period.

Derivative instruments are entered into for periods of time consistent with the related underlying exposures and are not entered into for speculative purposes. At the inception of a hedge, the Company documents all relationships between derivative instruments and related hedged items, as well as its risk-management objectives and strategies for the hedging transaction.

The Company's foreign currency forward contracts and interest rate swaps potentially expose the Company to credit risk to the extent the counterparties may be unable to meet the terms of the agreement. The Company minimizes such risk by seeking high quality counterparties.

Revenue Recognition. The Company derives revenue principally from sales of integrated manufacturing solutions, components and Company-proprietary products. Other sources of revenue include logistics and repair services; design, development and engineering services; defense and aerospace programs; and sales of raw materials to customers whose requirements change after the Company has procured inventory to fulfill the customer’s forecasted demand.

For purposes of determining when to recognize revenue, and in what amount, the Company applies a 5-step model: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the Company satisfies a performance obligation. Each of these steps involves the use of significant judgments.

The Company recognizes revenue for the majority of its contracts on an over time basis. This is due to the fact that 1) the Company does not have an alternative use for the end products it manufactures for its customers and has an enforceable right to payment, including a reasonable profit, for work-in-progress upon a customer’s cancelation of a contract for convenience or 2) the Company’s customer simultaneously receives and consumes the benefits provided by the Company’s services. For these contracts, revenue is recognized on an over time basis using the cost-to-cost method (ratio of costs incurred to date to total estimated costs at completion) which the Company believes best depicts the transfer of control to the customer. Revenue streams for which revenue is recognized on an over time basis include sales of vertically integrated manufacturing solutions (integrated manufacturing solutions and components); logistics and repair services; design, development and engineering services; and defense and aerospace programs.

For contracts for which revenue is required to be recognized at a point-in-time, the Company recognizes revenue when it has transferred control of the related goods, which generally occurs upon shipment or delivery of the goods to the customer. Revenue streams for which revenue is recognized at a point-in-time include Company-proprietary products and sales of raw materials.

Income taxes. The Company estimates its income tax provision or benefit in each of the jurisdictions in which it operates, including estimating exposures and making judgments regarding the realizability of deferred tax assets. The carrying value of the Company's net deferred tax assets is based on the Company's belief that it is more likely than not that the Company will generate sufficient future taxable income in certain jurisdictions to realize these deferred tax assets. A valuation allowance has been established for deferred tax assets which do not meet the “more likely than not” criteria discussed above.

The Company's tax rate is highly dependent upon the geographic distribution of its worldwide income or losses, the tax regulations and tax holidays in each geographic region, the availability of tax credits and carryforwards, including net operating losses, and the effectiveness of its tax planning strategies.

than not” recognition threshold, the Company then assesses the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with the tax authority. Interest and penalties related to unrecognized tax benefits are recognized as a component of income tax expense.

In March 2017, the FASB issued ASU 2017-07, "Compensation-Retirement Benefits (Topic 715)". This ASU requires the service costs component of net periodic pension costs to be presented in the same line item as other compensation costs and all other components of net periodic pension costs to be presented in the income statement as non-operating expenses. This ASU was effective for the Company at the beginning of fiscal 2019. The impact of adoption was insignificant.

In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805)". This ASU provides guidance to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This new standard was effective for the Company at the beginning of fiscal 2019. There was no impact upon adoption of this new standard.

In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230)". This ASU requires that the statement of cash flows explains the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Companies will also be required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. This ASU was effective for the Company at the beginning of fiscal 2019, including interim periods within that annual period. There was no impact upon adoption of this new standard.

In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory (Topic 740)". This ASU simplifies the accounting for income tax consequences of intra-entity transfers of assets other than inventory by requiring recognition of current and deferred income tax consequences when such transfers occur. The new standard was effective for the Company at the beginning of fiscal 2019. There was no impact upon adoption of this new standard.

In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers (Topic 606)" (commonly referred to as ASC 606) which requires an entity to recognize revenue when (or as) goods are transferred or services are provided to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services.

The Company adopted ASC 606 as of the beginning of its first quarter of 2019 using the modified retrospective approach, whereby the cumulative effect of initially applying the guidance was recognized as an adjustment to beginning retained earnings at the date of adoption. This adjustment resulted in an increase to beginning retained earnings of $28 million.

The adoption of ASC 606 resulted in a change to the manner in which the Company recognizes revenue for the majority of its revenue streams, including integrated manufacturing solutions, components, repair services and defense and aerospace programs.

Prior to the adoption of ASC 606, the Company generally recognized revenue from its integrated manufacturing solutions, the Company’s largest revenue stream, upon shipment or delivery of a product to a customer. Under ASC 606, because the Company has no alternative use for the end products generated by its vertically integrated manufacturing services and has an enforceable right to payment for work-in-progress upon a customer’s cancellation of a contract for convenience, the Company recognizes revenue from the sale of these products on an over time basis as the products are manufactured. Accordingly, the Company will recognize revenue under these contracts earlier than under the previous accounting rules.

Additionally, prior to the adoption of ASC 606, revenue from repair services was generally recognized upon completion of the services. Under ASC 606, revenue for these services will be recognized as the services are performed since the Company’s customers simultaneously receive and consume the benefits provided by these services.

Lastly, prior to the adoption of ASC 606, revenue from defense and aerospace programs was recognized on a percentage-of-completion basis by applying the units-of-delivery method. Under ASC 606, revenue for the majority of these programs will be recognized on an over time basis using the cost-to-cost method since the Company has no alternative use for the end products manufactured under these programs and has an enforceable right to payment for work-in-progress upon a customer’s cancellation of a contract for convenience. Revenue for certain other programs will be recognized upon shipment or delivery of a product, which is when control of a product transfers to a customer.

The timing of recognition of revenue did not change for some of the Company’s revenue streams as a result of the adoption of ASC 606. These revenue streams include logistics services, for which revenue will continue to be recognized as the services are performed, Company proprietary products, for which revenue will continue to be recognized upon shipment or delivery of the product, and design, development and engineering services for which revenue will continue to be recognized as the services are performed.

For revenue streams for which revenue is being recognized on an over time basis under ASC 606, work-in-progress and finished goods inventory were reduced to zero upon the adoption of ASC 606 and an associated contract asset was recorded to reflect amounts that would have been recognized as revenue prior to the adoption of ASC 606. This adjustment resulted in recognition of a contract asset of $376 million and a decrease in inventory of $350 million as of the beginning of the first fiscal quarter of 2019. No other balance sheet line items, with the exception of beginning retained earnings as mentioned previously, were materially impacted upon the adoption of ASC 606.

In August 2018, the FASB issued ASU 2018-15, "Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud-based hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU is effective for the Company at the beginning of fiscal 2021, including interim periods within that reporting period, although early adoption is permitted. The Company does not expect the impact of adoption to be significant.

In June 2018, the FASB issued ASU 2018-07 "Improvements to Non-employee Share-Based Payment Accounting (Topic 718)". The ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. The standard aligns measurement and classification guidance for share-based payments to non-employees with the guidance applicable to employees. This ASU is effective for the Company at the beginning of fiscal 2020, including interim periods within that reporting period. The Company does not expect the impact of adoption to be significant.

In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which allows companies to reclassify stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act (H.R. 1) from accumulated other comprehensive income to retained earnings. The guidance also requires certain new disclosures regardless of the election. This ASU is effective for the Company at the beginning of fiscal 2020. The Company does not expect the impact of adoption to be significant.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements for Accounting For Hedging Activities", simplifying hedge accounting guidance and improving the financial reporting of hedging relationships by allowing an entity to better align its risk management activities and financial reporting for hedging relationships through changes to both designation and measurement for qualifying hedging relationships and the presentation of hedge results. This standard eliminates the requirement to separately measure and report hedge ineffectiveness, resulting in full recognition of the change in fair value that impacts earnings in the same income statement line item that is used to present the earnings effect of the hedged item. In addition, the guidance allows more flexibility in the requirements to qualify for and maintain hedge accounting. This ASU is effective for the Company at the beginning of fiscal 2020. The Company does not expect the impact of adoption to be significant.

In June 2016, the FASB issued ASU 2016-13 "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments", which replaces the existing incurred loss impairment methodology with an expected credit loss methodology and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This new standard is effective for the Company at the beginning of fiscal 2021, including interim periods within that reporting period. The Company is currently evaluating the impact of adopting this new accounting standard.

In February 2016, the FASB issued ASU 2016-02, "Leases: Amendments to the FASB Accounting Standards Codification (Topic 842)". This ASU requires the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with terms of more than twelve months. This ASU also requires disclosures enabling the users of financial statements to understand the amount, timing and uncertainty of cash flows arising from leases. The new standard is effective for the Company at the beginning of fiscal 2020, including interim periods within that reporting period. In

addition, the FASB provided a practical expedient transition method that allows entities to initially apply the requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, as opposed to applying the requirements retrospectively and providing comparative prior period financial statements. The Company has decided to apply the above practical expedient transition method. The Company adopted the new standard on September 29, 2019, the first day of fiscal 2020. The Company elected certain other transition options which, among other things, allowed the Company to carry forward its prior conclusions about lease identification and classification.
