Litigation [Abstract]
Litigation	Litigation Plexus was notified in April 2009 by U.S. Customs and Border Protection (“CBP”) of its intention to conduct a customary Focused Assessment of the Company's import activities during fiscal 2008 and of its processes and procedures to comply with U.S. Customs laws and regulations. During September 2010, the Company reported errors relating to import trade activity from July 2004 to the date of Plexus' report. In August 2012, CBP issued its final determination of duties and fees owed by Plexus. The Company paid into a CBP-maintained escrow account the duties and fees claimed by CBP, pending a ruling from CBP Headquarters which could reduce the duties and fees owed by Plexus. Plexus has implemented improved processes and procedures and has reviewed these corrective measures with CBP. The Company recorded an accrual in other current accrued liabilities in the first quarter of fiscal 2010 when the amount became estimable and probable, which was not material to the financial statements. The accrual has been reduced to reflect the Company's payment into the CBP escrow account. At this time, Plexus does not believe that any deficiencies in processes or controls or unanticipated costs, unpaid duties or penalties associated with this matter will have a material adverse effect on Plexus or the Company's consolidated financial position, results of operations or cash flows. In fiscal 2010, the Company incurred approximately $1.1 million of costs relating to non-conforming inventory received from a supplier. The Company reached a settlement with the supplier during the first quarter of fiscal 2011 for $0.9 million, which was received and recorded in selling and administrative expenses in fiscal 2011. In fiscal 2010, the Company received settlement funds of approximately $3.2 million related to a court case in which the Company was a plaintiff. The settlement related to prior purchases of inventory and therefore was recorded as a reduction of cost of sales. The Company is party to certain other lawsuits in the ordinary course of business. Management does not believe that these proceedings, individually or in the aggregate, will have a material adverse effect on the Company’s consolidated financial position, results of operations or cash flows.
