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 interest rate swaps, contingent consideration and equity awards; and determining forfeiture rates, volatility and expected life assumptions 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, accounts payable and debt obligations. With the exception of certain of the Company's debt obligations (refer to Note 4. Fair Value and Note 5. Derivative Financial Instruments), the fair value of these financial instruments approximates their carrying amount as of October 3, 2015 and September 27, 2014 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 allowances of $13.4 million and $10.3 million as of October 3, 2015 and September 27, 2014, respectively, for uncollectible accounts, product returns and other 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. Inventories. Inventories are stated at the lower of cost (first-in, first-out method) or market. 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. Property, Plant and Equipment, net. 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 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. 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. 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. 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 (expense), net in the accompanying consolidated statements of income. 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 is therefore exposed to movements in foreign currency exchange rates. The Company uses foreign currency forward contracts to minimize the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. In the past, the Company has also used interest rate swaps to manage interest rate risk associated with certain long-term debt. 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 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 manufacturing services, components and other products. Other sources of revenue include order fulfillment, logistic and repair services, and sales of certain inventory, primarily raw materials, to customers whose requirements change after the Company has procured inventory to fulfill the customers' forecasted demand. The Company recognizes revenue for manufacturing services, components, products and sales of certain inventory when a persuasive arrangement between the Company and the buyer exists, usually in the form of a purchase order received from the Company's customer, the price is fixed or determinable, delivery or performance has occurred and collectability is reasonably assured. Generally, there are no formal customer acceptance requirements or further obligations related to the product or the inventory subsequent to transfer of title and risk of loss. The Company's order fulfillment and logistics services involve warehousing and managing finished product on behalf of a customer. These services are usually provided in conjunction with manufacturing services at one of the Company's facilities. In these instances, revenue for manufacturing services is deferred until the related goods are delivered to the customer, which is upon completion of order fulfillment and logistics services. In certain instances, the Company's facility used to provide order fulfillment and logistics services is controlled by the customer pursuant to a separate arrangement. In these instances, revenue for manufacturing services is recognized upon receipt of the manufactured product at the customer-controlled location and revenue for order fulfillment and logistics services is recognized separately as the services are provided. Revenue for repair services is generally recognized upon completion of the services. Provisions are made for estimated sales returns and other adjustments at the time revenue is recognized. Such provisions were not material to the consolidated financial statements for any period presented herein. The Company presents sales net of sales taxes and value-added taxes in its consolidated statements of income. Amounts billed to customers for shipping and handling are recorded as revenue and shipping and handling costs incurred by the Company are included in cost of sales. 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. In September 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (ASU) 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments (Topic 805)". This ASU requires the Company to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustments are determined. Additionally, the Company is required to disclose the amount recorded in current-period earnings that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The new guidance is effective for the Company in fiscal 2017. In July 2015, the FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory (Topic 330)". This ASU requires measurement of inventory at the lower of cost and net realizable value. Net realizable value is defined as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Currently, inventory is generally measured at the lower of cost or market, except for excess and obsolete inventories which are carried at their estimated net realizable values. This new standard is effective for the Company in fiscal 2018, including interim periods within that reporting period. The Company is currently evaluating the impact of adopting this new accounting standard. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605).” This ASU requires an entity to recognize revenue when goods are transferred or services are provided to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for the Company in fiscal 2019, including interim periods within that reporting period, using one of two prescribed transition methods. The Company is currently participating in an EMS industry forum that has been created to evaluate the impact of adoption of ASU 2014-09 on entities within such industry. The Company has not yet selected a transition method, nor has it determined the effect of the standard on its ongoing financial reporting.
