	Acquisitions and Divestitures
	In 2013, we completed two business combinations. One of these business combinations was in our Space and Defense Controls segment. We acquired Broad Reach Engineering for $34,550 of cash consideration, issuance of $8,450 of notes payable and contingent consideration with an initial fair value of $3,447. Based in Colorado, Broad Reach Engineering is a leading designer and manufacturer of spaceflight electronics and software for aerospace, scientific, commercial and military missions. The company also provides ground testing, launch and on-orbit operations. We also completed one business combination in our Components segment. We acquired Aspen Motion Technologies, located in Radford, Virginia for $33,911 in cash. Aspen is a designer and manufacturer of high-performance permanent magnet brushless DC motors, integrated digital controls and motorized impellers for motors. Aspen also specializes in custom motor designs for end product integration in a variety of high-performance industrial applications.

	Goodwill at September 28, 2013, in our Medical Devices reporting unit, is net of a $38,200 accumulated impairment loss. Certain factors, including industry conditions and the future profitability of our business might have a negative impact on the carrying value of our goodwill and we may incur additional goodwill impairment charges. We performed an interim test on goodwill for impairment of our Medical Devices reporting unit in the first quarter of 2014. We performed a quantitative assessment for this reporting unit and the fair value exceeded its carrying value. Therefore, there was no impairment of goodwill.
	The components of acquired intangible assets are as follows:

	All acquired intangible assets other than goodwill are being amortized. Customer-related intangible assets primarily consist of customer relationships. Program-related intangible assets consist of long-term programs represented by current contracts and probable follow on work. Technology-related intangible assets primarily consist of technology, patents, intellectual property and software. Marketing-related intangible assets primarily consist of trademarks, trade names and non-compete agreements.
	Amortization of acquired intangible assets was $7,548 and $15,111 for the three and six months ended March 29, 2014 and $8,053 and $15,794 for the three and six months ended March 30, 2013. Based on acquired intangible assets recorded at March 29, 2014, amortization is expected to be approximately $30,000 in 2014, $25,900 in 2015, $24,200 in 2016, $20,900 in 2017 and $19,000 in 2018.

	The Securitization Program matures on February 13, 2015 and effectively increases our borrowing capacity by up to $100,000. Under the Securitization Program, we sell certain trade receivables and related rights to an affiliate, which in turn sells an undivided variable percentage ownership interest in the trade receivables to a financial institution, while maintaining a subordinated interest in a portion of the pool of trade receivables. The Securitization Program can be extended by agreement of the parties thereto for successive 364-day terms. Interest for the Securitization Program is based on prevailing market rates for short-term commercial paper plus an applicable margin. A commitment fee is also charged based on a percentage of the unused amounts available and is not material. The agreement governing the Securitization Program contains restrictions and covenants which include limitations on the making of certain restricted payments, creation of certain liens, and certain corporate acts such as mergers, consolidations and sale of substantially all assets. The Securitization Program has a minimum borrowing requirement equal to the lesser of either 80% of our borrowing capacity or 100% of our borrowing base. As of March 29, 2014, our minimum borrowing requirement is $80,000.
	In addition to the Securitization Program, we maintain short-term credit facilities with banks throughout the world that are principally demand lines subject to revision by the banks.
	On December 19, 2013, we repurchased our 7¼% senior subordinated notes due on January 15, 2018 at 103.625%, pursuant to an early redemption right. We redeemed the aggregate principal amount of $200,000 using proceeds drawn from our U.S. revolving credit facility. The associated loss on the redemption includes $6,945 of call premium paid to external bondholders and a $1,057 write off of deferred debt issuance costs.
	On January 15, 2013, we repurchased at par our 6¼% senior subordinated notes due on January 15, 2015, pursuant to an early redemption right. We redeemed the aggregate principal amount of $200,000 using proceeds drawn from our U.S. revolving credit facility.

Derivative Instruments and Hedges, Assets [Abstract]	'
Derivative Financial Instruments	'
	Derivative Financial Instruments
	We principally use derivative financial instruments to manage interest rate risk associated with long-term debt and foreign exchange risk related to foreign operations and foreign currency transactions. We enter into derivative financial instruments with a number of major financial institutions to minimize counterparty credit risk.
	Derivatives designated as hedging instruments
	Interest rate swaps are used to adjust the proportion of total debt that is subject to variable and fixed interest rates. The interest rate swaps are designated as hedges of the amount of future cash flows related to interest payments on variable-rate debt that, in combination with the interest payments on the debt, convert a portion of the variable-rate debt to fixed-rate debt. At March 29, 2014, we had interest rate swaps with notional amounts totaling $120,000. The interest rate swaps effectively convert this amount of variable-rate debt to fixed-rate debt at 1.5%, including the applicable margin of 113 basis points as of March 29, 2014. The interest will revert back to variable rates based on LIBOR plus the applicable margin upon the maturity of the interest rate swaps on January 15, 2015 and January 15, 2016.
	We use foreign currency forward contracts as cash flow hedges to effectively fix the exchange rates on future payments and revenue. To mitigate exposure in movements between various currencies, primarily the Philippine peso, we had outstanding foreign currency forwards with notional amounts of $40,235 at March 29, 2014. These contracts mature at various times through December 23, 2015.
	These interest rate swaps and foreign currency forwards are recorded in the consolidated condensed balance sheets at fair value and the related gains or losses are deferred in shareholders’ equity as a component of Accumulated Other Comprehensive Income (Loss) (AOCI). These deferred gains and losses are reclassified into expense during the periods in which the related payments or receipts affect earnings. However, to the extent the interest rate swaps and foreign currency forwards are not perfectly effective in offsetting the change in the value of the payments and revenue being hedged, the ineffective portion of these contracts is recognized in earnings immediately. Ineffectiveness was not material in the first six months of 2014 or 2013.
	Derivatives not designated as hedging instruments
	We also have foreign currency exposure on balances, primarily intercompany, that are denominated in foreign currencies and are adjusted to current values using period-end exchange rates. The resulting gains or losses are recorded in the consolidated condensed statements of earnings. To minimize foreign currency exposure, we had foreign currency forwards with notional amounts of $217,280 at March 29, 2014. The foreign currency forwards are recorded in the consolidated condensed balance sheets at fair value and resulting gains or losses are recorded in the consolidated condensed statements of earnings. We recorded the following gains or losses on foreign currency forwards which are included in other income or expense and generally offset the gains or losses from the foreign currency adjustments on the intercompany balances that are also included in other income or expense:

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Fair Value
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, various techniques and assumptions can be used to estimate fair value. The definition of the fair value hierarchy is as follows:
	Level 1 – Quoted prices in active markets for identical assets and liabilities.
	Level 2 – Observable inputs other than quoted prices in active markets for similar assets and liabilities.
	Level 3 – Inputs for which significant valuation assumptions are unobservable in a market and therefore value is based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require.
	Our derivatives are valued using various pricing models or discounted cash flow analyses that incorporate observable market data, such as interest rate yield curves and currency rates, and are classified as Level 2 within the valuation hierarchy. Our Level 3 fair value liabilities represent contingent consideration recorded for acquisitions to be paid if various financial targets are met. The amounts recorded were calculated for each payment scenario in each period using an estimate of the probability of the future cash outflows. The varying contingent payments were then discounted to the present value at the weighted average cost of capital. Fair value is assessed on a quarterly basis, or whenever events or circumstances change that indicates an adjustment is required. The assessment includes an evaluation of the performance of the acquired business compared to previous expectations, changes to future projections and the probability of achieving the earn out targets.
	The following table presents the fair values and classification of our financial assets and liabilities measured on a recurring basis as of March 29, 2014:
