Basis Of Presentation And Accounting Policies	'
	BASIS OF PRESENTATION AND ACCOUNTING POLICIES
	Basis of Presentation
	The accompanying condensed consolidated financial statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). In the opinion of the Company, the accompanying condensed consolidated financial statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the consolidated financial position of the Company as of June 28, 2014 and September 28, 2013, and the results of operations for the three and nine months ended June 28, 2014 and June 29, 2013, and the cash flows for the same nine month periods.
	Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted pursuant to the SEC’s rules and regulations dealing with interim financial statements. However, the Company believes that the disclosures made in the condensed consolidated financial statements included herein are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2013 Annual Report on Form 10-K.
	The Company’s reportable segments consist of the “Americas” (“AMER”) segment, “Asia-Pacific” (“APAC”) segment and “Europe, Middle East, and Africa” (“EMEA”) segment. Refer to Note 9, "Business Segments," for further details on reportable segments.
	Cash and Cash Equivalents
	Cash and cash equivalents include highly liquid investments with original maturities of three months or less at the time of purchase and are classified as Level 1 in the fair value hierarchy described below.
	Fair Value of Financial Instruments
	The Company holds financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable, debt, derivatives, and capital lease obligations. The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and capital lease obligations as reported in the condensed consolidated financial statements approximate fair value. Derivatives are recorded at fair value. Accounts receivable are reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses are based on management’s analysis of historical losses and changes in customers’ credit status. The fair value of the Company’s long-term debt was $248.6 million and $246.8 million as of June 28, 2014 and September 28, 2013, respectively. The carrying value of the Company’s long-term debt was $250.0 million for both the periods ended June 28, 2014 and September 28, 2013. The Company uses quoted market prices when available or discounted cash flows to calculate the fair value of its debt. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described below. Refer to Note 5, "Derivatives and Fair Value Measurements," for further details on derivatives.
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:
	Level 1: Quoted (observable) market prices in active markets for identical assets or liabilities.
	Level 2: Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.
	Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability.

	INVENTORIES
	Inventories are stated at the lower of cost (on a first-in, first-out basis) or fair value. The stated cost is comprised of direct materials, labor, and overhead. The major classes of inventories, net of applicable lower of cost or fair value write-downs, were as follows (in thousands):
		June 28,		September 28,
		2014		2013
	Raw materials	$	360,410	$	288,559

	Finished goods	70,707		57,578
		$	516,956	$	404,020
	Per contractual terms, customer deposits are received by the Company to offset obsolete and excess inventory risks. The total amount of customer deposits related to inventory and included within current liabilities on the accompanying Condensed Consolidated Balance Sheets as of June 28, 2014 and September 28, 2013 was $46.4 million and $51.6 million, respectively.

	Property, plant and equipment consisted of the following categories (in thousands):
		June 28,		September 28,
		2014		2013
	Land, buildings and improvements	$	268,205	$	212,195

	Less: accumulated depreciation	378,945		359,158
		$	338,379	$	325,061
	The reduction in the construction in progress balance at June 28, 2014 was primarily due to the capitalization of assets related to the construction of the Company's new manufacturing facility in Neenah, Wisconsin that opened in the fiscal first quarter of 2014. This reduction was partially offset by increases in the construction in progress balance primarily due to footprint expansion in Guadalajara, Mexico. The most significant component of the construction in progress balance at June 28, 2014 was related to footprint expansion in Guadalajara and the most significant component of the construction in progress balance at September 28, 2013 was related to facility construction in Neenah.

	DEBT
	On May 15, 2014, the Company entered into an amendment (the "Amendment") to its credit agreement, dated as of May 15, 2012 (as amended, the "Credit Agreement"), related to its five-year senior unsecured credit facility (the “Credit Facility”). As a result of the Amendment, the Credit Facility, which was formerly a $250.0 million facility consisting of a $160.0 million revolving credit facility and a $90.0 million term loan (balance of $75.0 million as of May 15, 2014), was converted into a $235.0 million revolving credit facility, and its termination date was extended from May 15, 2017 to May 15, 2019. The Credit Facility may potentially be increased by $100.0 million to $335.0 million generally by mutual agreement of the Company and the lenders, subject to certain customary conditions. Quarterly principal repayments on the former term loan of $3.8 million per quarter ended on March 28, 2013. As of June 28, 2014, the Company had $75.0 million of revolving borrowings outstanding under the Credit Facility. In the fiscal third quarter of 2014, the Company borrowed and repaid $87.0 million of revolving borrowings under the Credit Facility.
	The financial covenants (as defined under the Credit Agreement) require that the Company maintain, as of each fiscal quarter end, a maximum total leverage ratio and a minimum interest coverage ratio. As of June 28, 2014, the Company was in compliance with all financial covenants of the Credit Agreement. Borrowings under the Credit Facility, at the Company's option, bear interest at a defined base rate or the LIBOR rate plus, in each case, an applicable margin based upon the Company's leverage ratio as defined in the Credit Agreement. Rates would increase upon negative changes in specified Company financial metrics and would decrease to no less than LIBOR plus 1.00% or base rate plus 0.00% upon reduction in the current total leverage ratio. As of June 28, 2014, the Company had a borrowing rate of LIBOR plus 1.13%. As of June 28, 2014, all outstanding debt under the Credit Facility is effectively at a fixed interest rate as a result of the interest rate swap contract discussed in Note 5, "Derivatives and Fair Value Measurements." There is no floating rate debt outstanding under the Credit Facility as of June 28, 2014. The Company is required to pay an annual commitment fee on the unused revolver credit commitment based on the Company's leverage ratio; the fee was 0.2% as of June 28, 2014.
	In the fiscal third quarter of 2014, the Company incurred approximately $0.2 million in new debt issuance costs in connection with the Amendment. These costs, along with the remaining unamortized portion of the $0.9 million in new debt issuance costs the Company incurred in May 2012, are being amortized over the five-year term of the Credit Facility.
	The Company also has outstanding 5.20% Senior Notes, due on June 15, 2018 (the “Notes”); $175.0 million principal of the Notes was outstanding as of both June 28, 2014 and September 28, 2013. At June 28, 2014, the Company was in compliance with all financial covenants relating to the Notes, which are consistent with those in the Credit Agreement discussed above.
	In the fiscal third quarter of 2014, the Company capitalized certain leased property, plant and equipment related to footprint expansion in Guadalajara, for which the Company had direct involvement in construction and will have ongoing involvement subsequent to the completion of construction. This resulted in a non-cash financing transaction of approximately $8.0 million and is reflected in long-term debt and capital lease obligations on the accompanying Condensed Consolidated Balance Sheets as of June 28, 2014.

Derivatives And Fair Value Measurements	'
	DERIVATIVES AND FAIR VALUE MEASUREMENTS
	All derivatives are recognized in the accompanying Condensed Consolidated Balance Sheets at their estimated fair value. The Company uses derivatives to manage the variability of foreign currency obligations and interest rates. The Company has cash flow hedges related to variable rate debt and forecasted foreign currency obligations, in addition to fair value hedges to manage foreign currency exposures associated with certain foreign currency denominated assets and liabilities. The Company does not enter into derivatives for speculative purposes. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in “Accumulated other comprehensive income” in the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of the cash flows. Changes in the fair value of the derivatives related to recognized foreign currency denominated assets and liabilities are recorded in "Other income (expense)" in the accompanying Condensed Consolidated Statements of Comprehensive Income.
	The Company enters into forward currency exchange contracts on a rolling basis. The Company had cash flow hedges outstanding with a notional value of $64.6 million as of June 28, 2014. These forward currency contracts fix the exchange rates for the settlement of future foreign currency obligations that have yet to be realized. The total fair value of the cash flow hedges was a $1.8 million asset as of June 28, 2014 and a $1.0 million liability as of September 28, 2013.
	The Company had additional forward currency exchange contracts outstanding with a notional value of $37.9 million as of June 28, 2014. The Company has not designated these derivative instruments as hedging instruments. The net settlement amount (fair value) related to these contracts is recorded on the Condensed Consolidated Balance Sheets as either a current or long-term asset or liability, depending on the term, and as an element of other income (expense). The total fair value of these derivatives was a $0.3 million liability as of June 28, 2014. No contracts were outstanding as of September 28, 2013.
	On June 4, 2013, the Company entered into an interest rate swap contract to replace the three interest rate swap contracts that matured on April 4, 2013, as described below. This interest rate swap contract is related to $75.0 million of borrowings outstanding under the Credit Facility, as amended. This interest rate swap pays the Company variable interest at the one month LIBOR rate, and the Company pays the counterparty a fixed interest rate. The fixed interest rate for the contract is 0.875%. Based on the terms of the interest rate swap contract and the underlying borrowings outstanding under the Credit Facility, as amended, the interest rate contract was determined to be effective, and thus qualifies as a cash flow hedge. As such, any changes in the fair value of the interest rate swap are recorded in “Accumulated other comprehensive income” on the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of cash flows. The total fair value of the interest rate swap contract was a $0.1 million liability as of June 28, 2014 and a $0.1 million asset as of September 28, 2013. The notional amount of the Company’s interest rate swap was $75.0 million as of both June 28, 2014 and September 28, 2013.
	The Company previously entered into three interest rate swap contracts related to the former term loans under its prior credit facility. These contracts had an initial total notional value of $150.0 million and matured on April 4, 2013, which resulted in a $2.0 million discrete tax benefit in the three months ended June 29, 2013. The fixed interest rates for each of these contracts were 4.415%, 4.490% and 4.435%, respectively. These interest rate swap contracts were originally entered into to convert $150.0 million of the variable rate term loan under the prior credit facility into fixed rate debt. Based on the terms of the interest rate swap contracts and the underlying debt, these interest rate contracts were determined to be effective, and thus qualified as a cash flow hedge. As such, any changes in the fair value of these interest rate swaps were recorded in “Accumulated other comprehensive income” on the accompanying Condensed Consolidated Balance Sheets until earnings were affected by the variability of cash flows.

	For the three and nine months ended June 28, 2014, the derivative instruments that are not designated as hedging instruments resulted in the recognition of a $1.7 million loss and a $1.3 million loss, respectively, which was substantially offset by changes in the underlying recognized value of foreign currency denominated assets and liabilities for both periods. This activity was recorded in other income (expense) on the Condensed Consolidated Statement of Comprehensive Income.
	The following table lists the fair values of assets/(liabilities) of the Company’s derivatives as of June 28, 2014, by input level as defined above (in thousands):

	Foreign currency forward contracts - not designated as hedging instruments		$	—			$	(264	)		$	—			$	(264	)
	The fair value of interest rate swaps and foreign currency forward contracts is determined using a market approach which includes obtaining directly or indirectly observable values from third parties active in the relevant markets. The primary input in the fair value of the interest rate swaps is the relevant LIBOR forward curve. Inputs in the fair value of the foreign currency forward contracts include prevailing forward and spot prices for currency and interest rate forward curves.

	For the three and nine months ended June 28, 2014, stock options and stock-settled stock appreciation rights ("SARs") for approximately 0.5 million and 0.6 million shares, respectively, were not included in the computation of diluted earnings per share because the options' and stock-settled SARs' exercise prices were greater than the average market price of the Company's common shares and, therefore, their effect would be anti-dilutive.
	For both the three and nine months ended June 29, 2013, stock options and stock-settled SARs for approximately 2.0 million shares were not included in the computation of diluted earnings per share because the options' and stock-settled SARs' exercise prices were greater than the average market price of the Company's common shares and, therefore, their effect would be anti-dilutive.
	The Company's stock repurchase programs impacted the number of shares outstanding for the three and nine months ended June 28, 2014 as compared to the three and nine months ended June 29, 2013.

	The Company uses the Black-Scholes valuation model to determine the fair value of stock options and stock-settled SARs. The Company uses the fair value at the date of grant to value restricted stock units ("RSUs") and unrestricted stock awards. The Company recognizes stock-based compensation expense over the stock-based awards’ vesting period.
	In the fiscal first quarter of 2014, the Company modified its long-term incentive strategy to include grants of performance share units ("PSUs"). The Company uses the Monte Carlo valuation model to determine the fair value of PSUs at the date of grant. The PSUs are payable in shares and vest based on the relative total shareholder return of the Company's common stock as compared to the Russell 3000 Index during a three year performance period. The number of shares that may be issued pursuant to PSUs ranges from zero to 0.1 million. The Company recognizes stock-based compensation expense over the PSUs’ vesting period.

	INCOME TAXES
	Income tax expense for the three and nine months ended June 28, 2014 was $2.6 million and $3.5 million, respectively. The effective tax rates for the three and nine months ended June 28, 2014 were 9.6 percent and 5.5 percent, respectively, as compared to (1.1) percent and 4.6 percent for the three and nine months ended June 29, 2013, respectively. The increase in the tax expense and effective tax rate for the three months ended June 28, 2014, as compared to the three months ended June 29, 2013, was primarily the result of a discrete benefit related to the settlement of an interest rate swap occurring in the fiscal third quarter of 2013 as well as the geographic distribution of worldwide earnings. The increase in the tax expense and effective tax rate for the nine months ended June 28, 2014, as compared to the nine months ended June 29, 2013, was primarily a result of the geographic distribution of worldwide earnings, partially offset by a larger discrete benefit related to the release of reserves from the closure of federal and state tax audits occurring in the nine months ended June 28, 2014, relative to the discrete benefit that occurred in the nine months ended June 29, 2013.
	As demonstrated in recent quarters, the Company's effective tax rate fluctuates depending on the geographic distribution of its worldwide earnings.
	There were no material additions to the amount of unrecognized tax benefits recorded for uncertain tax positions as of June 28, 2014 as compared to fiscal 2013 year end. The Company recognizes accrued interest and penalties related to the remaining uncertain tax positions in income tax expense. The amount of interest and penalties recorded for both the three and nine months ended June 28, 2014 was not material.
	It is reasonably possible that a number of uncertain tax positions may be settled within the next 12 months. The Company is currently under examination by various state taxing authorities in the U.S. The Company is not currently undergoing any tax examinations in any of the foreign jurisdictions in which the Company has significant operations.
	The Company maintains valuation allowances when it is more likely than not that all or a portion of a deferred tax asset will not be realized. During the three and nine months ended June 28, 2014, the Company continued to record a full valuation allowance against its net deferred tax assets in the U.S., Germany, Romania and the U.K., as it is more likely than not that these assets will not be fully realized based primarily on historical performance. The Company will continue to provide a valuation allowance against its net deferred tax assets in each of the applicable jurisdictions going forward until the need for a valuation allowance is eliminated. The need for a valuation allowance will be eliminated when the Company determines it is more likely than not that the deferred tax assets will be realized.

Segment Reporting [Abstract]	'
Business Segments	'
	BUSINESS SEGMENTS
	Reportable segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and allocating resources.
	The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company’s resources on a regional basis. Net sales for segments are attributed to the region in which the product is manufactured or service is performed. The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its operating income (loss). A segment’s operating income (loss) includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other costs, interest expense, other income (loss), and income taxes. Corporate and other costs primarily represent corporate selling and administrative expenses, and restructuring and impairment costs, if any. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Inter-segment transactions are generally recorded at amounts that approximate arm’s length transactions. The accounting policies for the regions are the same as for the Company taken as a whole.
	Information about the Company’s three reportable segments for the three and nine months ended June 28, 2014 and June 29, 2013, respectively, follows (in thousands):

	GUARANTEES
	The Company offers certain indemnifications under its customer manufacturing agreements. In the normal course of business, the Company may from time to time be obligated to indemnify its customers or its customers’ customers against damages or liabilities arising out of the Company’s negligence, misconduct, breach of contract, or infringement of third party intellectual property rights. Certain agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material.
	In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon specifications for periods generally ranging from 12 months to 24 months. If a product fails to comply with the Company’s limited warranty, the Company’s obligation is generally limited to correcting, at its expense, any defect by repairing or replacing such defective product. The Company’s warranty generally excludes defects resulting from faulty customer-supplied components, design defects or damage caused by any party or cause other than the Company.
	The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes additional reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement and are included in the Company’s accompanying Condensed Consolidated Balance Sheets in other current accrued liabilities. The primary factors that affect the Company’s warranty liability include the value and the number of shipped units and historical and anticipated rates of warranty claims. As these factors are impacted by actual experience and future expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.
	Below is a table summarizing the activity related to the Company’s limited warranty liability for fiscal 2013 and for the nine months ended June 28, 2014 (in thousands):
	Limited warranty liability, as of September 29, 2012	$	5,145

	RESTRUCTURING AND IMPAIRMENT COSTS
	Restructuring and impairment costs, primarily incurred in the Company's AMER segment, largely relate to the consolidation of the Company's facilities in the Fox Cities (Neenah and Appleton), Wisconsin and the relocation of manufacturing operations from Juarez, Mexico to Guadalajara, Mexico. These charges are recorded within restructuring and impairment charges on the Condensed Consolidated Statements of Comprehensive Income. Restructuring liabilities are recorded within other accrued liabilities on the Condensed Consolidated Balance Sheets.
	For the three months ended June 28, 2014, the Company incurred restructuring costs of $1.2 million, which consisted of the following:
	•	$0.7 million of severance from the anticipated reduction of the Company's workforce in Juarez; and
	•	$0.5 million primarily related to a loss on an asset sale related to the consolidation of the Company's facilities in the Fox Cities.
	For the nine months ended June 28, 2014, the Company incurred restructuring and impairment costs of $10.9 million, which consisted of the following:
	•	$3.2 million of fixed asset impairment at the Company's Juarez facility;
	•	$3.3 million of severance from the reduction of the Company's workforce in Juarez, the Fox Cities and the United Kingdom; and
	•	$4.4 million of rent, moving and associated costs resulting from the early exit of operating leases for two existing Neenah facilities and the consolidation of three existing Fox Cities facilities into the new Neenah manufacturing facility.
	As part of the relocation of manufacturing operations from Juarez to Guadalajara, the Company evaluated the ongoing fair value of the plant and equipment associated with the Juarez facility. Based on this evaluation, the Company determined that long-lived assets were impaired and therefore recorded $3.2 million of fixed asset impairment during the nine months ended June 28, 2014. Fair value was evaluated using Level 3 inputs, as defined in Note 1.
	The Company cannot recognize an income tax benefit for restructuring and impairment costs due to existing tax losses in these jurisdictions.
	The Company's restructuring accrual activity for the three months ended June 28, 2014 is included in the table below (in millions):

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
New Accounting Pronouncements	'
	NEW ACCOUNTING PRONOUNCEMENTS
	In May 2014, the Financial Accounting Standards Board ("FASB") issued amended guidance for revenue recognition. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under current guidance. This may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. Companies have the option of using either a full or modified retrospective approach in applying this standard. The Company is currently in the process of evaluating the impact of adoption on its consolidated financial statements.
	In April 2014, the FASB issued final guidance that changes the criteria for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The revised guidance defines a discontinued operation as (1) a component of an entity or group of components that has been disposed of by sale, disposed of other than by sale or is classified as held for sale that represents a strategic shift that has or will have a major effect on an entity's operations and financial results or (2) an acquired business or nonprofit activity that is classified as held for sale on the date of acquisition. The guidance does not change the presentation requirements for discontinued operations in the statement where net income is presented but does require the reclassification of assets and liabilities of a discontinued operation in the statement of financial position for all prior periods presented. The guidance is effective prospectively for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years, and for all businesses that, on acquisition, are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in previously issued financial statements. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued new guidance for unrecognized tax benefits that exist along with a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The guidance requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for an net operating loss ("NOL") carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. This guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption and retrospective application are permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued amended guidance that permits the Fed Funds Effective Swap Rate (also referred to as the Overnight Index Swap Rate, or "OIS") to be used as a U.S. benchmark interest rate for hedge accounting purposes, in addition to Treasury obligations of the U.S. government ("UST") and the London Interbank Offered Rate ("LIBOR"). The amendments also remove the restriction on using different benchmark rates for similar hedges. This update is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements or results of operations.
	In March 2013, the FASB issued amended guidance for cumulative translation adjustments upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. These amendments provide guidance on releasing cumulative translation adjustments when a reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity.  In addition, these amendments provide guidance on the release of cumulative translation adjustment in partial sales of equity method investments and in step acquisitions.  The amendments are effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

	The accompanying condensed consolidated financial statements included herein have been prepared by Plexus Corp. and its subsidiaries (together “Plexus” or the “Company”) without audit and pursuant to the rules and regulations of the United States (“U.S.”) Securities and Exchange Commission (“SEC”). In the opinion of the Company, the accompanying condensed consolidated financial statements reflect all adjustments, which include normal recurring adjustments necessary for the fair statement of the consolidated financial position of the Company as of June 28, 2014 and September 28, 2013, and the results of operations for the three and nine months ended June 28, 2014 and June 29, 2013, and the cash flows for the same nine month periods.
	Certain information and footnote disclosures, normally included in financial statements prepared in accordance with generally accepted accounting principles, have been condensed or omitted pursuant to the SEC’s rules and regulations dealing with interim financial statements. However, the Company believes that the disclosures made in the condensed consolidated financial statements included herein are adequate to make the information presented not misleading. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2013 Annual Report on Form 10-K.
	The Company’s reportable segments consist of the “Americas” (“AMER”) segment, “Asia-Pacific” (“APAC”) segment and “Europe, Middle East, and Africa” (“EMEA”) segment. Refer to Note 9, "Business Segments," for further details on reportable segments.
Cash And Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents include highly liquid investments with original maturities of three months or less at the time of purchase and are classified as Level 1 in the fair value hierarchy described below.
Fair Value Of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company holds financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable, debt, derivatives, and capital lease obligations. The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and capital lease obligations as reported in the condensed consolidated financial statements approximate fair value. Derivatives are recorded at fair value. Accounts receivable are reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses are based on management’s analysis of historical losses and changes in customers’ credit status. The fair value of the Company’s long-term debt was $248.6 million and $246.8 million as of June 28, 2014 and September 28, 2013, respectively. The carrying value of the Company’s long-term debt was $250.0 million for both the periods ended June 28, 2014 and September 28, 2013. The Company uses quoted market prices when available or discounted cash flows to calculate the fair value of its debt. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described below. Refer to Note 5, "Derivatives and Fair Value Measurements," for further details on derivatives.
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are:
	Level 1: Quoted (observable) market prices in active markets for identical assets or liabilities.
	Level 2: Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.
	Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability.
