Organization and Summary of Significant Accounting Policies (Notes)	12 Months Ended
	Sep. 27, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Organization and Summary of Significant Accounting Policies	'
	Organization and Summary of Significant Accounting Policies
	Organization and Basis of Presentation:  CPI International Holding LLC (“Holding LLC”), owns all of the outstanding common stock of CPI International Holding Corp., headquartered in Palo Alto, California (“Successor” or “Parent”), the parent company of CPI International, Inc. (“CPII”). CPII, in turn, owns all of the outstanding equity interests of Communications & Power Industries LLC (formerly, Communications & Power Industries, Inc., “CPI”) and Communications & Power Industries Canada Inc. (“CPI Canada”), CPII’s main operating subsidiaries. Holding LLC, Parent and CPII are holding companies with no material assets or operations other than their respective direct or indirect equity interests in CPI and CPI Canada and activities related thereto.
	On February 11, 2011, CPI International LLC (formerly, CPI International, Inc., “Predecessor”), then a Delaware corporation and publicly traded company, completed its merger with Catalyst Acquisition, Inc. (“Merger Sub”), a Delaware corporation and wholly owned subsidiary of CPII (formerly, CPI International Acquisition, Inc.), a Delaware corporation, whereby Merger Sub merged with and into Predecessor (the “Merger”), with Predecessor continuing as the surviving corporation and a wholly owned subsidiary of CPII. The Merger was effected pursuant to the Agreement and Plan of Merger, dated as of November 24, 2010, among Predecessor, CPII and Merger Sub (the "Merger Agreement"). Immediately following the consummation of the Merger, Predecessor was converted into a limited liability company and liquidated, and CPI International Acquisition, Inc. changed its name to CPI International, Inc.
	As used herein, unless the context indicates or otherwise requires, (i) for periods prior to the Merger, the term “Company” refers to Predecessor and its consolidated subsidiaries, and for periods after the Merger, the term refers to Successor, its consolidated subsidiaries and, where the context so requires, its direct and indirect parent companies.
	The Company develops, manufactures and distributes microwave and power grid electron devices, microwave amplifiers, modulators, antenna systems and various other power supply equipment and devices. The Company has two reportable segments: electron devices and satcom equipment.
	The accompanying consolidated financial statements represent the consolidated results and financial position of the Company. The Company’s fiscal year is the 52- or 53-week period that ends on the Friday nearest September 30. Fiscal years 2013, 2012 and 2011 comprise the 52-week periods ending September 27, 2013, September 28, 2012 and September 30, 2011, respectively.
	The consolidated financial statements include those of the Company and its subsidiaries. Significant intercompany balances, transactions, and stockholdings have been eliminated in consolidation.
	Foreign Currency Translation:    The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Gains or losses resulting from the translation into U.S. dollars of amounts denominated in foreign currencies are included in the determination of net income or loss. Foreign currency translation gains and losses are generally reported on a net basis in the caption “general and administrative” in the consolidated statements of comprehensive income (loss), except for translation gains or losses on income tax-related assets and liabilities, which are reported in “income tax expense” in the consolidated statements of comprehensive income (loss).
	Use of Estimates:    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of sales and costs and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition; inventory valuation; recoverability and valuation of recorded amounts of long-lived assets and identifiable intangible assets, including goodwill; recognition and measurement of current and deferred income tax assets and liabilities; and business combinations. The Company bases its estimates on various factors and information, which may include, but are not limited to, history and prior experience, experience of other enterprises in the same industry, new related events, current economic conditions and information from third-party professionals that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
	Revenue Recognition:    Sales are recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. The Company’s products are generally subject to warranties, and the Company provides for the estimated future costs of repair, replacement or customer accommodation in cost of sales.
	Revenue arrangements that include multiple deliverables are divided into separate units of accounting if the deliverables meet certain criteria. The Company allocates the consideration among the separate units of accounting based on their relative selling prices, and considers the applicable revenue recognition criteria separately for each of the separate units of accounting. The Company applies a selling price hierarchy for determining the selling price of a deliverable in a sale arrangement. The selling price for each deliverable is based on vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available, or estimated selling price if neither VSOE or TPE is available.
	The Company has commercial and U.S. Government fixed-price contracts that are accounted for under the accounting guidance for construction-type and production-type contracts. These contracts have represented not more than 4% of the Company’s sales during fiscal years 2013 and 2012 and each of the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011, and are for contracts that generally are greater than one year in duration and that include a significant amount of product development. The Company uses the percentage-of-completion method when reasonably dependable estimates of the extent of progress toward completion, contract revenues and contract costs can be made. The portion of revenue earned or the amount of gross profit earned for a period is determined by measuring the extent of progress toward completion using total cost incurred to date and estimated costs at contract completion.
	Sales under cost-reimbursement contracts, which are primarily for research and development, are recorded as costs are incurred and include estimated earned fees in the proportion that costs incurred to date bear to total estimated costs. The fees under certain commercial and U.S. Government contracts may be increased or decreased in accordance with cost or performance incentive provisions that measure actual performance against established targets or other criteria. Such incentive fee awards or penalties are included in revenue at the time the amounts can be reasonably determined.
	Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.
	Cash and Cash Equivalents:  The Company considers all highly liquid short-term investments with original maturities of three months or less, readily convertible to known amounts of cash to be cash equivalents.
	Restricted Cash:  Restricted cash consists of bank guarantees from customer advance payments to the Company’s international subsidiaries and cash collateral for certain performance bonds. The bank guarantees become unrestricted cash when performance under the sales or supply contract is complete. The cash collateral for the performance bonds becomes unrestricted cash when the performance bonds expire.
	Inventories:  Inventories are stated at the lower of average cost or market value. The Company uses a combination of standard cost and moving weighted-average cost methodologies to determine the cost basis for its inventories, approximating a first-in, first-out basis. Costs include labor, material and overhead costs. Overhead costs are based on indirect costs allocated among cost of sales, work-in-process inventory and finished goods inventory. Inventories also include costs and earnings in excess of progress billings for contracts using the percentage-of-completion method of accounting. Progress billings in excess of costs and earnings for contracts using the percentage-of-completion method of accounting are reported in Advance Payments from Customers.
	The Company assesses the valuation of inventory and periodically writes down the value for estimated excess and obsolete inventory based upon actual usage and estimates about future demand. The excess balance determined by this analysis becomes the basis for the Company’s excess inventory charge. Management personnel play a key role in the excess inventory review process by providing updated sales forecasts, managing product rollovers and working with manufacturing to maximize recovery of excess inventory. If actual market conditions are less favorable than those projected by management, additional write-downs may be required. If actual market conditions are more favorable than anticipated, inventory previously written down may be sold, resulting in lower cost of sales and higher income from operations than expected in that period.
	Management also reviews the carrying value of inventory for lower of cost or market on an individual product or contract basis. A loss is charged to cost of sales when known if estimated product or contract cost at completion is in excess of net realizable value (selling price less estimated cost of disposal). If actual product or contract cost at completion is different than originally estimated, then a loss or gain provision adjustment is recorded that would have an impact on the Company’s operating results.
	Property, Plant and Equipment:    Property, plant and equipment are stated at cost. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Plant and equipment are depreciated over their estimated useful lives using the straight-line method. Building, land improvements and process equipment are depreciated generally over 25, 20 and 12 years, respectively. Machinery and equipment are depreciated generally over seven to 12 years. Office furniture and equipment are depreciated generally over five to 10 years. Leasehold improvements are amortized using the straight-line method over their estimated useful lives, or the remaining term of the lease, whichever is shorter.
	Goodwill and Other Intangible Assets:    The Company accounts for business combinations using the purchase method of accounting in which intangible assets acquired are recognized and reported apart from goodwill.
	The values assigned to acquired identifiable intangible assets for technology were determined based on the excess earnings method of the income approach. This method determines fair market value using estimates and judgments regarding the expectations of future after-tax cash flows from those assets over their lives, including the probability of expected future contract renewals and sales, all of which are discounted to their present value.
	Goodwill and identifiable intangible assets with indefinite useful lives are tested for impairment at least annually. Intangible assets subject to amortization are amortized over their respective estimated useful lives and reviewed for impairment. Identifiable intangible assets are amortized on a straight-line basis over their useful lives of up to 40 years. The Company tests goodwill for impairment annually or more frequently if events and circumstances warrant. The Company’s annual testing resulted in no impairment of goodwill in fiscal years 2013 and 2012 and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011.
	Long-Lived Assets:    Long-lived and finite-lived intangible assets, including property, equipment and leasehold improvements, are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. Such impairment loss would be measured as the difference between the carrying amount of the asset and its fair value.
	There were no triggering events identified that would indicate a need to review for impairment of long-lived assets during fiscal years 2013 and 2012 and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011.
	Deferred Debt Issue Costs:    Costs incurred related to the issuance of the Company’s long-term debt and other credit facilities are capitalized and amortized over the estimated time the obligations are expected to be outstanding using the effective interest method. Deferred debt issue costs for CPII’s revolving credit facility, term loan and 8% Senior Notes due 2018 are amortized over the term to maturity of the respective debt of five years, six years and seven years, respectively.
	Product Warranty:    The Company’s products typically carry warranty periods of one to three years or warranties over a predetermined product usage life. The Company estimates the costs that may be incurred under its warranty plans and records a liability in the amount of such estimated costs at the time revenue is recognized. The determination of product warranty reserves requires the Company to make estimates of product return rates and expected cost to repair or replace the products under warranty. The Company assesses the adequacy of its preexisting warranty liabilities and adjusts the balance based on actual experience and changes in future expectations.
	Business Risks and Credit Concentrations:    Defense-related applications, such as certain radar, electronic countermeasures and military communications applications, constitute a significant portion of the Company’s sales. Companies engaged in supplying defense-related equipment and services to government agencies are subject to certain business risks unique to that industry. Sales to the government may be affected by changes in procurement policies, budget considerations, changing concepts of national defense, political developments abroad and other factors.
	Research and Development: Company-sponsored research and development costs related to both present and future products are expensed as incurred. Customer-sponsored research and development costs are charged to cost of sales to match revenue recognized. Total expenditures incurred by the Company on research and development are summarized as follows:
		Successor						Predecessor
		Year Ended				Period		Period
						February 11 to		October 2, 2010 to
		September 27,		September 28,		September 30,		February 10,
		2013		2012		2011		2011
	CPI-sponsored	$	14,602	$	13,499	$	9,798	$	4,994
	Customer-sponsored	12,151		14,692		13,054		5,042
		$	26,753	$	28,191	$	22,852	$	10,036
	Customer-sponsored research and development represents development costs incurred on customer sales contracts to
	develop new or improved products. Prior to the first quarter of fiscal year 2012, the Company disclosed customer-sponsored research and development based on the amount charged to costs of sales upon revenue recognition rather than the amount of expenditures incurred for these activities as the development work was performed. For comparative purposes, amounts for periods prior to fiscal year 2012 presented above have been adjusted to conform to current period presentation.
	Advertising Expenses:  Costs related to advertising are recognized in selling and marketing expenses as incurred. Advertising expenses were not material in any of the periods presented.
	Income Taxes:    The Company records income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on the two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.
	Income tax-related interest expense or income, foreign exchange gains and losses and penalties are reported as components of the provision for income taxes in the consolidated statements of comprehensive income (loss).
	See Note 13 for further discussion on income taxes.
	Comprehensive Income:    Comprehensive income is defined as a change in equity of a company during a period from transactions and other events and circumstances, excluding transactions resulting from investments by owners and distributions to owners. The difference between net income and comprehensive income for the Company arises from unrealized gains and losses on cash flow hedge contracts, net of tax, and unrealized actuarial gains and losses and prior service costs and credits for pension liability, net of tax.

Accounting Changes and Error Corrections [Abstract]	'
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-08, “Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment,” intended to simplify how an entity tests goodwill for impairment. ASU 2011-08 allows an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The results of this qualitative assessment will determine whether a quantitative impairment test must be performed. ASU 2011-08 was effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company adopted ASU 2011-08 in connection with its annual goodwill impairment test performed in the fourth quarter of fiscal year 2013. The adoption of this ASU did not have a material impact on the Company’s consolidated results of operations, financial position or cash flows.
	In November 2011, the FASB issued ASU 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Offsetting, otherwise known as netting, is the presentation of assets and liabilities as a single net amount in the statement of financial position (balance sheet). In January 2013, the FASB issued ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities,” which clarifies that the scope of ASU 2011-11 applies to derivatives accounted for in accordance with Topic 815, “Derivatives and Hedging,” including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset or subject to an enforceable master netting arrangement or similar arrangement. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods, and should provide the required disclosures retrospectively for all comparative periods presented. This ASU will be effective for the Company beginning in the first quarter of fiscal year 2014. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated results of operations, financial position or cash flows.
	In July 2012, the FASB issued ASU 2012-02, “Intangibles-Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment.” ASU 2012-02 amends the guidance in Accounting Standards Codification (“ASC”) 350-302 on testing indefinite-lived intangible assets, other than goodwill, for impairment by allowing an entity to perform a qualitative impairment assessment before proceeding to the two-step impairment test. If the entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is not more likely than not (i.e., a likelihood of more than 50% impaired, the entity would not need to calculate the fair value of the asset. In addition, ASU 2012-02 does not amend the requirement to test these assets for impairment between annual tests if there is a change in events or circumstances; however, it does revise the examples of events and circumstances that an entity should consider in interim periods. ASU 2012-02 was effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company adopted ASU 2012-02 in connection with its annual indefinite-lived intangible assets impairment test performed in the fourth quarter of fiscal year 2013. The adoption of this ASU did not have a material impact on the Company’s consolidated results of operations, financial position or cash flows.
	In February 2013, the FASB issued ASU 2013-02, “Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which amends ASC 220, “Comprehensive Income.” The amended guidance requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. Additionally, entities are required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amended guidance does not change the current requirements for reporting net income or other comprehensive income. The amendment is effective prospectively for annual periods, and interim periods within those annual periods, beginning after December 15, 2012. This ASU will be effective for the Company beginning in the first quarter of fiscal year 2014. As this ASU addresses disclosure requirements only, its adoption is not expected to have a material impact on the Company’s consolidated results of operations, financial position or cash flows.
	In July 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This update clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Retrospective application is permitted. This ASU will be effective for the Company beginning in the first quarter of fiscal year 2015. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated results of operations, financial position or cash flows.

Business Combinations [Abstract]	'
Business Combination Disclosure	'
	Business Combinations
	All of the Company’s business combinations constitute transactions or events in which an acquirer obtains control of one or more “businesses” or a “business combination” and, accordingly, are accounted for under the acquisition method of accounting in which Parent or the Company is deemed to be the accounting acquirer. Under this method of accounting, all assets acquired and liabilities assumed are recorded at their respective fair values at the date of the completion of each transaction. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, intangibles and other asset lives, among other items.
	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 (an exit price). Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. As a result, the Company may have been required to value the acquired assets at fair value measures that do not reflect its intended use of those assets. Use of different estimates and judgments could yield different results. Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill.
	MCL
	On June 25, 2013, the Company completed its acquisition of certain assets of M C L, Inc., (“MCL”), an Illinois corporation and a manufacturer of power amplifier products and systems for the satellite communications market and a wholly owned subsidiary of MITEQ, Inc., a Delaware corporation, for a payment of approximately $6.0 million in cash. The acquisition was funded entirely from the Company’s cash on hand and was made to support the strategic growth of the Company. MCL, which will soon operate a manufacturing facility in Lisle, Illinois, has been integrated into the Company’s Satcom Division as a part of the Company’s satcom equipment operating segment. The results of MCL’s operations were included in the Company’s consolidated results of operations beginning on the date of the acquisition.
	In connection with the acquisition of MCL, the Company incurred various expenses totaling $1.1 million and $0.3 million, included in “general and administrative” and “cost of sales,” respectively, in the consolidated statement of comprehensive income for fiscal year 2013. The general and administrative costs, which the Company expensed as incurred, consist primarily of professional fees payable to financial and legal advisors and retention bonuses payable to employees.
	The following table reflects the final allocation of the total purchase price to the fair values of net assets acquired and the resulting goodwill:
	Purchase price	$	5,982
	Less: Fair value of assets acquired:
	Net current assets	(3,559		)
	Property, plant and equipment	(1,040		)
	Identifiable intangible assets	(590		)
		(5,189		)
	Goodwill	$	793
	Measurement period adjustments to fair values identified during the fourth quarter of fiscal year 2013 included a decrease in identifiable intangible assets of approximately $0.8 million, an increase in net assets of approximately $0.7 million and an increase in property, plant and equipment of approximately $0.6 million. As a result of these adjustments and an increase in purchase price of $0.6 million, there was a net increase in goodwill of approximately $0.1 million. Measurement period adjustments represent updates made to the preliminary purchase price allocation based on new information obtained in the interim period subsequent to the acquisition and initial accounting date up to one year from the acquisition date.
	The fair value assigned to identifiable intangible assets acquired was determined using variations of the income approach. Under these methods, fair value is estimated based upon the present value of cash flows that the applicable asset is expected to generate. The valuation of completed technology and trade names was based on the relief-from-royalty method, and customer relationship was valued using the excess earnings method. The royalty rates used in the relief-from royalty method were based on both a return-on-asset method and market comparable rates. The Company believes that these identifiable intangible assets will have no residual value after their estimated economic useful lives.
	Goodwill resulted from the MCL acquisition is largely attributable to future growth opportunities within the Company's communications market and is deductible for income tax purposes.
	The fair value of the identifiable intangible assets and their weighted-average useful lives are as follows:
		Estimated				Estimated
		Fair Value				Useful Life
						(years)
	Tradenames	$	20			1
	Completed technology	110				7-Jan
	Customer relationship	460				10
	Total identifiable intangible assets	$	590
	All of the above identifiable intangible assets are definite-lived and are amortized over their estimated useful lives.
	Pro forma information is not provided as the MCL acquisition in fiscal year 2013 did not have a material effect on the Company’s consolidated results.
	Codan Satcom
	On June 30, 2012, the Company completed its acquisition of the Codan Satcom business from Codan Limited, an
	Australian-based public company, for a payment of approximately $7.5 million in cash. The acquisition was funded entirely from the Company’s cash on hand. Codan Satcom designs and manufactures solid-state radio frequency (“RF”) subsystems for satellite communications services to commercial and government customers. The acquisition of Codan Satcom expands the Company’s portfolio of solid-state and satellite communications products and enables the Company to offer customers the most complete line of satellite communications amplifiers, operating at all satellite uplink frequencies and power levels, in the industry. Codan Satcom, which consists of operations based in Newton, South Australia and the Locus Microwave operations based in Boalsburg, Pennsylvania, was integrated into the Company’s Communications & Medical Products Division in Ontario, Canada as a part of the Company’s electron devices operating segment. The results of Codan Satcom’s operations were included in the Company’s consolidated results of operations beginning on the date of the acquisition.
	In connection with the acquisition of Codan Satcom, the Company incurred various expenses totaling $2.0 million and $1.5 million included in “general and administrative” in the consolidated statements of comprehensive income for fiscal years 2013 and 2012, respectively, consisting primarily of stamp duty (an Australian asset transfer tax), professional fees payable to financial and legal advisors, expenses related to moving the operation from Australia to North America and start-up expenses, all of which the Company expensed as incurred.
	The following table reflects the final allocation of the total purchase price to the fair values of assets acquired and the liabilities assumed and the resulting goodwill:
	Purchase price	$	7,516
	Less: Fair value of assets acquired:
	Net current assets	(2,500		)
	Property, plant and equipment	(2,868		)
	Identifiable intangible assets	(1,370		)
	Deferred tax assets	(630		)
		(7,368		)
	Add: Fair value of liabilities assumed:
	Contingent consideration liability	56
	Goodwill	$	204
	The fair value assigned to identifiable intangible assets acquired was determined using variations of the income approach. Under these methods, fair value is estimated based upon the present value of cash flows that the applicable asset is expected to generate. The valuation of completed technology and trade names was based on the relief-from-royalty method; and customer relationship was valued using the excess earnings method. The royalty rates used in the relief-from royalty method were based on both a return-on-asset method and market comparable rates. The Company believes that these identifiable intangible assets will have no residual value after their estimated economic useful lives.
	Goodwill resulted from the Codan Satcom acquisition is largely attributable to future growth opportunities within the Company's solid-state communications market and is deductible for income tax purposes.
	The fair value of the identifiable intangible assets and their weighted-average useful lives are as follows:
		Estimated				Estimated
		Fair Value				Useful Life
						(years)
	Tradenames	$	40			5
	Completed technology	1,000				10
	Customer relationship	330				12
	Total identifiable intangible assets	$	1,370
	All of the above identifiable intangible assets are definite-lived and are amortized over their estimated useful lives.
	In connection with, and as part of the consideration for, the acquisition of Codan Satcom, the Company was obligated to make a maximum of $4.5 million in potential additional payments if certain revenue targets were achieved over the two years following the acquisition. The valuation of the contingent consideration liability was based on a probability-weighted discounted cash flow analysis. See Note 5 for additional information on the fair value of the contingent consideration.
	The Merger
	In connection with the Merger described in Note 1, The Veritas Capital Fund IV, L.P., The Veritas Capital Fund III, L.P. and their affiliates, including CICPI Holdings LLC (collectively, “Veritas Capital”) invested $186.0 million, and certain officers of CPII invested an aggregate amount of $11.1 million solely for the purpose of purchasing equity securities of Holding LLC in order to provide a portion of the financing required for the Merger and the transactions contemplated by the Merger Agreement. The $197.1 million total equity investment is net of $14.0 million merger and acquisition fees, including merger-related expenses, that were paid upon or shortly after the Merger closing. Veritas Capital is a private equity firm that specializes in making investments in companies that provide products and services to government-related end markets and customers around the world, including those in healthcare, education, energy, defense, infrastructure, national security and aerospace.
	The consideration paid pursuant to the Merger was approximately $370.5 million, primarily comprised of $19.50 cash per share of Predecessor’s outstanding common stock, restricted stock units, restricted stock awards and shares issuable pursuant to vested stock options (less the per-share exercise price thereof, as applicable). The purchase price was net of $5.2 million cash paid for the unvested portion of the stock awards for which vesting was accelerated as of the closing date in accordance with the terms of the Merger Agreement. Cash payments made by the acquirer in a business combination to settle unvested stock awards were immediately expensed after the acquisition date in the post combination financial statements. This amount is included in “strategic alternative transaction expenses” in the consolidated statement of comprehensive loss for the period February 11, 2011 to September 30, 2011.
	In connection with the Merger and previous activities which ultimately resulted in consummation of the Merger, the Company incurred various expenses, also recorded as “strategic alternative transaction expenses” in the consolidated statements of comprehensive income (loss), consisting primarily of professional fees payable to financial and legal advisors that the Company expensed as incurred.
	The following table reflects the final allocation of the total purchase price to the fair values of assets acquired and the
	liabilities assumed and the resulting goodwill:
	Purchase price		$	370,490
	Less: Fair value of assets acquired:
	Net current assets		(111,501		)
Property, plant and equipment		(82,879		)
Identifiable intangible assets		(274,980		)
Other long-term assets		(7,417		)
		(476,777		)
Add: Fair value of liabilities assumed:
Deferred tax liabilities		85,563
Long-term debt		195,487
Other long-term liabilities		3,967
		285,017
Goodwill		$	178,730
The fair value assigned to identifiable intangible assets acquired was determined using variations of the income approach. Under these methods, fair value is estimated based upon the present value of cash flows that the applicable asset is expected to generate. The valuation of core technology and trade names was based on the relief-from-royalty method; developed technology, backlog and in-process research and development (“IPR&D”) were valued using the excess earnings method; and leasehold interests were valued using discounted cash flows method. The royalty rates used in the relief-from royalty method were based on both a return-on-asset method and market comparable rates. The Company believes that these identifiable intangible assets will have no residual value after their estimated economic useful lives.
Goodwill resulted from the Merger was attributable to CPII’s assembled workforce, market position, competitive position, revenue base and industry trends, as well as expanded sponsorship opportunities. Goodwill recorded in connection with the Merger is not deductible for income tax purposes.
The fair value of the identifiable intangible assets and their weighted-average useful lives are as follows:
	Estimated				Estimated
	Fair Value				Useful Life
					(years)
Definite-lived assets:
Division tradenames	$	2,900			15
Core technology	94,400				40
Completed technology	88,100				15 - 25
Backlog	15,300				2-Jan
Leasehold interest	35,680				Apr-40
In-process research and development	3,500				10
Total definite-lived assets	239,880
Indefinite-lived assets:
CPI tradenames	35,100				Indefinite
Total indefinite-lived assets	35,100
Total identifiable intangible assets	$	274,980
Definite-lived intangible assets are amortized over their estimated useful lives. Intangible assets with indefinite useful lives and goodwill are not amortized but are tested for impairment annually.
The acquired IPR&D consisted of the in-process project to complete development of the next generation of the Company’s medical x-ray generators. The value assigned to IPR&D was determined by considering the importance of products under development to the overall development plan, estimating costs to develop the purchased IPR&D into commercially viable products, estimating the resulting net cash flows from the projects when completed and discounting the net cash flows to their present value. This methodology is referred to as the income approach, which discounts expected future cash flows to present value. The discount rate used in the present value calculations was derived from a weighted-average cost of capital analysis, adjusted to reflect additional risks related to the product’s development and success as well as the product’s stage of completion. An acquired IPR&D asset is initially recognized at fair value and, during the development period after the acquisition date, is not amortized as a charge to earnings; instead this asset is subject to periodic impairment testing. The development process for the acquired IPR&D project was successfully completed during the third quarter of fiscal year 2012 and, therefore amortization of the acquired IPR&D commenced at that time.
In connection with the Merger, the Company issued $215.0 million aggregate principal amount of 8% senior notes due 2018 and entered into senior secured credit facilities, comprised of a $150.0 million six-year term loan facility and a $30.0 million five-year revolving credit facility. See Note 6, Long-term Debt, for details. In addition, shortly after the date of the Merger, Predecessor purchased or redeemed all of its then-existing outstanding senior subordinated notes and floating rate senior notes and repaid its outstanding indebtedness under the then-existing senior credit facilities. Net costs incurred in the repayment of principal of all prior long-term debt was $0.1 million, recorded as “loss on debt extinguishment” in the consolidated statement of comprehensive loss for the period February 11, 2011 to September 30, 2011.
Other
On February 13, 2012, the Company completed a business combination in which the Company acquired selected assets of a small company that repaired and rebuilt vacuum electron devices for the communications, industrial, scientific and medical markets for cash consideration of $0.4 million. The Company recorded $0.2 million of identifiable intangible assets and $0.2 million of net tangible assets, which comprised primarily inventory. The Company included the financial results of this business combination in its consolidated results of operations beginning on the acquisition date; however, the impact of this acquisition was not material to the Company’s consolidated results of operations, financial position or cash flows.

Fair Value Measurements [Abstract]	'
Financial Instruments Disclosure	'
	Financial Instruments
	Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value is calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities includes consideration of non-performance risk, including the Company’s own credit risk.
	The Company uses a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three levels of the fair value hierarchy are described as follows:
	Level 1	Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
	Level 2	Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the asset or the liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
	Level 3	Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.
	The Company transfers assets or liabilities from one level to another when the methodology to obtain the fair value changes such that there are more or fewer unobservable inputs as of the end of the reporting period.
	The Company’s non-financial assets (including goodwill, intangible assets, inventories and long-lived assets) and liabilities are measured at fair value on a non-recurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances, such as when they are deemed to be impaired. The fair values of these non-financial assets and liabilities are determined based on valuation techniques using the best information available, and may include quoted market prices, market comparables and discounted cash flow projections. During all periods presented, no fair value adjustments or material fair value measurements were required for the Company’s non-financial assets or liabilities other than the initial recognition of assets and liabilities in connection with business combinations. The estimated fair values of tangible and intangible assets and liabilities recorded in connection with business combinations are based on Level 3 inputs. See Note 3 for more information.
	The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, available-for-sale securities, derivative instruments and contingent consideration. As of September 27, 2013 and September 28, 2012, financial assets utilizing Level 1 inputs included cash equivalents, such as money market and overnight U.S. Government securities and available-for-sale securities, such as mutual funds. Financial assets and liabilities utilizing Level 2 inputs included foreign currency derivatives. As of September 28, 2012, the financial liability utilizing Level 3 inputs included the contingent consideration arising from the acquisition of Codan Satcom.
	The following tables set forth financial instruments carried at fair value within the hierarchy:

	4 The liability position of foreign currency derivatives is classified as part of accrued expenses in the consolidated balance sheet.
	5 The contingent consideration liability is classified as part of other long-term liabilities in the consolidated balance sheet.
	Investments Other Than Derivatives
	In general and where applicable, the Company uses quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing methodology applies to the Company’s Level 1 investments, such as money market, U.S. Government securities and mutual funds.
	If quoted prices in active markets for identical assets or liabilities are not available to determine fair value, then the Company would use quoted prices for similar assets and liabilities or inputs other than the quoted prices that are observable either directly or indirectly. These investments would be included in Level 2.
	Derivatives
	The Company executes foreign exchange forward contracts to purchase Canadian dollars in the retail market with its relationship banks. To determine the most appropriate value, the Company uses an in-exchange valuation premise which considers the assumptions that market participants would use in pricing the derivatives. The Company has elected to use the income approach and uses observable (Level 2) market expectations at the measurement date and standard valuation techniques to convert future amounts to a single present amount. Level 2 inputs for derivative valuations are midmarket quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability.
	Key inputs for currency derivatives are spot rates, forward rates, interest rates and credit derivative rates. The spot rate for the Canadian dollar is the same spot rate used for all balance sheet translations at the measurement date. Forward premiums/discounts and interest rates are interpolated from commonly quoted intervals. Once valued, each forward is identified as either an asset or liability. Assets are further discounted using counterparty annual credit default rates, and liabilities are valued using the Company’s credit as reflected in the spread paid over LIBOR on the term loan under the Company’s senior credit facilities.
	See Note 8 for further information regarding the Company’s derivative instruments.
	Contingent Consideration
	As part of the consideration for Codan Satcom acquisition (Note 3), the potential earn-out payments were considered contingent consideration. This contingent consideration was measured at fair value at the acquisition date and has been re-measured to fair value at each reporting date until the contingency is resolved. The fair value of the contingent consideration was based on a probabilistic calculation whereby the Company assigned estimated probabilities to achieving the earn-out targets and then discounted the total contingent consideration to net present value using Level 3 inputs. The Company believes the discount rate used to discount the earn-out payments reflected market participant assumptions. As of September 27, 2013 and September 28, 2012, the estimated fair value of the contingent consideration was zero and $0.1 million, respectively, and was classified as “other long-term liability” in the consolidated balance sheets. During fiscal year 2013, the Company determined that the earn-out revenue targets would not be met. The Company, therefore, recorded a gain of $0.1 million in “general and administrative” in the consolidated statement of comprehensive income for fiscal year 2013 from the reversal of the contingent consideration liability.
	Other Financial Instruments
	The Company’s other financial instruments include cash, restricted cash, accounts receivable, accounts payable, accrued expenses and long-term debt. Except for long-term debt, the carrying value of these financial instruments approximates fair values because of their relatively short maturity.
	The fair value of the Company’s long-term debt is estimated based on quoted market prices from the trading desk of a nationally recognized investment bank. In previous periods, the Company presented the long-term debt under Level 1 of the fair value hierarchy. Upon further analysis of market activity, given that the Company’s senior notes are only available to investors through certain brokerage firms and, as a result, are not considered actively traded, the Company has classified this debt under Level 2 of the fair value hierarchy as of September 27, 2013 and September 28, 2012. The estimated fair value of the Company’s long-term debt as of September 27, 2013 and September 28, 2012 using Level 2 fair value inputs was $365.7 million and $352.3 million, respectively, compared to the carrying value of $358.7 million and $361.8 million, respectively.

	Senior Secured Credit Facilities
	In connection with the Merger, in February 2011, CPII entered into the Senior Secured Credit Facilities with UBS AG, Stamford Branch, as administrative agent, and the other financial institutions party thereto (“Senior Credit Facilities”). The Senior Credit Facilities are structured as (a) a $150.0 million, six-year term loan facility (“Term Loan”); and (b) a $30.0 million five-year revolving credit facility (“Revolver”) that includes sub-limits for letters of credit and swingline loans. In addition, the Senior Credit Facilities permit CPII to add one or more incremental facilities to the term loan facility and/or increase commitments under the revolving credit facility in an aggregate principal amount of up to $50.0 million, subject to receipt of commitments for such term loans or increases. CPII borrowed the full amount of the Term Loan in connection with the Merger, and the Revolver was undrawn at September 27, 2013 (other than for approximately $3.8 million of outstanding letters of credit).
	Borrowings under the Term Loan and the Revolver bear interest, at CPII’s option, at either (a) a base rate equal to the highest of (i) the federal funds rate, plus 0.50%, (ii) the corporate base rate of interest established by the administrative agent and (iii) adjusted LIBOR for an interest period of one month beginning on such day plus 1%, or (b) LIBOR, in each case plus an applicable margin. For all purposes, LIBOR shall never be deemed to be less than a specified “LIBOR floor.” As of September 27, 2013, the variable interest rate on the Term Loan was 5.0%.
	CPII is also required to pay a commitment fee to the lenders under the Revolver in respect of unutilized commitments thereunder. The commitment fee is 0.75% per annum. In addition, CPII is required to pay customary fees in connection with the issuance of letters of credit.
	The Senior Credit Facilities require CPII to prepay outstanding loans, subject to certain exceptions, with:
	•	100% of the net cash proceeds received from the sale or other disposition of all or any part of the assets of the Parent or any of its restricted subsidiaries in excess of $15.0 million, other than sales of inventory in the ordinary course of business and other than amounts reinvested in assets to be used in CPII’s business within 12 months of such disposition (or if committed to be reinvested within such 12 months, reinvested within 18 months of such disposition) and subject to other exceptions;
	•	100% of the net proceeds received by the Parent or any of its restricted subsidiaries from the issuance of debt or disqualified preferred stock after the Closing Date, other than debt permitted under the Senior Credit Facilities;
	•	100% of all casualty and condemnation proceeds received by the Parent or any of its restricted subsidiaries in excess of $15.0 million, other than amounts reinvested in assets to be used in CPII’s business within 12 months of such receipt (or if committed to be reinvested within such 12 months, reinvested within 18 months of such receipt) and subject to other exceptions; and
	•	50% of excess cash flow (“ECF”) of the Parent and its restricted subsidiaries, such percentage to be reduced based on the Parent attaining certain leverage ratios. The first ECF prepayment was based on ECF for fiscal year 2012. The ECF prepayment is required to be made within five business days of issuing the year-end consolidated financial statements. Based on the results for fiscal year 2013, an ECF prepayment of $5.5 million is required to be made during the first quarter of fiscal year 2014. Based on the results for fiscal year 2012, CPII made a prepayment of $3.2 million during the first quarter of fiscal year 2013.
	CPII may also voluntarily prepay outstanding loans under the Senior Credit Facilities in whole or in part, with prior notice but without premium or penalty (except LIBOR breakage costs) and including accrued and unpaid interest, subject to limitations as to minimum amounts of prepayments.
	Mandatory prepayments will be applied first to scheduled installments of the Term Loan (and allocated to such scheduled installments in direct order to the next eight scheduled installments and thereafter to the remaining scheduled installments on a pro rata basis) until paid in full, second to the Revolver and third to cash collateralize outstanding letters of credit. Voluntary prepayments of loans (including loans under the Revolver to the extent accompanied by permanent reductions of the commitments thereunder), other than prepayments funded with the proceeds of indebtedness, will be credited against excess cash flow prepayment obligations on a dollar-for-dollar basis.
	The Term Loan facility amortizes in equal quarterly installments in annual amounts equal to 1.0% of the original principal amount of the term loan facility, with the balance payable on the maturity date of the term loan facility. The Revolver does not amortize.
	CPII’s obligations under the Senior Credit Facilities are fully and unconditionally guaranteed by the Parent and, subject to certain exceptions, each of the Parent’s existing and future domestic restricted subsidiaries (other than CPII). In addition, CPII’s obligations under the Senior Credit Facilities and the guarantees of those obligations are secured by substantially all of CPII’s assets and all the assets of the guarantors, including but not limited to (a) pledges of all the equity interests held by CPII and each guarantor and (b) a first-priority security interest in, and mortgages on, substantially all of the present and after-acquired assets of CPII and each guarantor, in each case subject to certain exceptions.
	The Senior Credit Facilities contain a number of covenants that, among other things, restrict, subject to certain exceptions, the ability of the Parent and its restricted subsidiaries, including CPII, to:
	•	dispose of assets and make changes in business;
	•	incur additional indebtedness or issue preferred stock or prepay, amend or redeem certain indebtedness;
	•	create liens on assets and make further negative pledges;
	•	enter into sale and leaseback transactions;
	•	engage in mergers or acquisitions;
	•	pay dividends or distributions or repurchase or redeem capital stock or make other restricted payments;
	•	make investments, loans or advances;
	•	make capital expenditures;
	•	engage in certain transactions with affiliates;
	•	amend charter documents and material agreements in a manner adverse in any material respect to the lenders without their consent;
	•	change accounting policies;
	•	permit certain restrictions affecting subsidiaries; and
	•	change the status of Parent as a holding company.
	The Senior Credit Facilities also include financial covenants that apply to the Parent and its restricted subsidiaries and consist of a minimum cash interest coverage ratio and a maximum total leverage ratio. In addition, the Senior Credit Facilities contain certain customary affirmative covenants and events of default.
	As of September 27, 2013, the principal balance of the Term Loan was $143.7 million, net of issue discount of $0.4 million. At September 27, 2013, the amount available for borrowing under the Revolver, after taking into account the Company‘s outstanding letters of credit of $3.8 million, was approximately $26.2 million.
	8% Senior Notes due 2018
	In February 2011, CPII issued $215.0 million in aggregate principal amount of its 8.00% Senior Notes due 2018 (the “8% Notes”). Total proceeds from the issuance of the 8% Notes were $208.6 million, net of $6.4 million issuance costs. The 8% Notes bear interest at the rate of 8.0% per year, payable semi-annually in arrears on each February 15 and August 15. The 8% Notes will mature on February 15, 2018. The 8% Notes are unsecured obligations, jointly and severally guaranteed by the Parent and, subject to certain exceptions, all of the Parent’s existing and future domestic restricted subsidiaries (other than CPII).
	The 8% Notes and the guarantees will be senior unsecured obligations of CPII and each of the guarantors, as applicable, and are equal in right of payment with all of CPII’s and such guarantor’s existing and future senior unsecured obligations. The 8% Notes and the guarantees thereof are senior in right of payment to any of CPII’s and each guarantor’s existing and future obligations that are, by their terms, expressly subordinated in right of payment to the 8% Notes and the guarantees. The 8% Notes and the guarantees thereof are effectively subordinated to CPII’s and each guarantor’s existing and future secured obligations, including the Senior Credit Facilities, to the extent of the value of the assets securing such obligations.
	At any time or from time to time on or after February 15, 2015, CPII, at its option, may redeem the 8% Notes, in whole or in part, at the redemption prices (expressed as percentages of principal amount) set forth below, together with accrued and unpaid interest thereon, if any, to the redemption date, if redeemed during the 12-month period beginning February 15 of the years indicated:
			Optional Redemption Price
	Year
	2015		104	%
	2016		102	%
	2017 and thereafter		100	%
	In addition, at any time prior to February 15, 2015, CPII may redeem all or a part of the 8% Notes at a redemption price equal to 100% of the principal amount of the 8% Notes to be redeemed plus an applicable premium (as defined in the indenture governing the 8% Notes) plus accrued and unpaid interest, if any, to, the redemption date.
	At any time before February 15, 2014, CPII may redeem up to 35% of the aggregate principal amount of the 8% Notes issued under the indenture with the net cash proceeds of one or more qualified equity offerings at a redemption price equal to 108% of the principal amount of the 8% Notes to be redeemed, plus accrued and unpaid interest.
	Upon a change of control, CPII may be required to purchase all or any part of the 8% Notes for a cash price equal to 101% of the principal amount, plus accrued and unpaid interest thereon, if any, to the date of purchase.
	The indenture governing the 8% Notes contains a number of covenants that, among other things, restrict, subject to certain exceptions, the ability of CPII and its restricted subsidiaries (as defined in the indenture governing the 8% Notes) to incur additional indebtedness, pay dividends or repurchase or redeem capital stock, limit dividends or other payments by its restricted subsidiaries to CPII or its other restricted subsidiaries, make certain investments, incur liens, enter into certain types of transactions with CPII’s affiliates, and sell assets or consolidate or merge with or into other companies.
	As of September 27, 2013, the principal balance of the 8% Notes was $215.0 million.
	Debt Maturities:    As of September 27, 2013, maturities on long-term debt were as follows:
	Fiscal Year		Term			8% Senior		Total
			Loan			Notes
	2014		$	5,500		$	—	$	5,500
	2015		—			—		—
	2016		—			—		—
	2017		138,675			—		138,675
	2018		—			215,000		215,000
			$	144,175		$	215,000	$	359,175
	The above table assumes that the respective debt instruments will be outstanding until their scheduled maturity dates. The table also reflects the required ECF prepayment under the Senior Credit Facilities of $5.5 million payable in the first quarter of fiscal year 2014. The remaining mandatory quarterly repayments have been removed from the table above due to such ECF prepayment and the ECF prepayment made during fiscal year 2013. The above table does not reflect future ECF or other optional prepayments, if any, that may be required under the Senior Credit Facilities.
As of September 27, 2013, the Company was in compliance with the covenants under the agreements governing the Senior Credit Facilities and the indentures governing the 8% Notes.
Deferred Debt Issuance Costs

	Employee Benefit Plans
	Retirement Plans:    The Company provides a qualified 401(k) investment plan covering substantially all of its domestic employees and a pension contribution plan covering substantially all of its Canadian employees. The Company also has a Non-Qualified Deferred Compensation Plan (the “Non-Qualified Plan”) that allows a select group of management and highly compensated employees to defer a portion of their compensation. The Non-Qualified Plan liability recorded by the Company amounted to approximately $1.3 million and $0.9 million as of September 27, 2013 and September 28, 2012, respectively. For all of the Company’s current retirement plans, all participant contributions and Company matching contributions are 100% vested. Total CPI contributions to these retirement plans were $3.8 million, $3.7 million, $2.3 million and $1.3 million for fiscal years 2013 and 2012, and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011, respectively.
	Defined Benefit Pension Plan: The Company maintains a defined benefit pension plan for its Chief Executive Officer (“CEO”). The plan’s benefits are based on the CEO’s compensation earnings and are limited by statutory requirements of the Canadian Income Tax Act. All costs of the plan are borne by the Company.
	At September 27, 2013 and September 28, 2012, the Company recorded a liability of $0.2 million and $0.7 million, respectively, which approximates the excess of the projected benefit obligation over plan assets of $1.3 million and $1.2 million, respectively. The projected benefit obligation as of September 27, 2013 was reduced by a deferred actuarial gain brought about by a change in the assumed discount rate. Generally, when the assumed discount rate increases compared to the prior measurement date, a deferred actuarial gain is created. The net of the deferred gains and losses are amortized to pension expense over the average service life of the plan participant, when it exceeds certain pre-defined thresholds. Additionally, the Company recorded an unrealized gain of $0.1 million, net of tax of $47,000 as of September 27, 2013 and unrealized loss of $0.3 million, net of tax of $0.1 million as of September 28, 2012 to “accumulated other comprehensive income” in the consolidated balance sheets.
	The Company’s defined benefit pension plan is managed by an insurance company consistent with regulations or market practice in Canada, where the plan assets are invested. Net pension expense, recorded in “general and administrative” in the consolidated statements of comprehensive income (loss), was $0.1 million for each fiscal year 2013 and 2012, and not material for the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011. Contributions to the plan are not expected to be significant to the financial position of the Company.

	Derivative Instruments and Hedging Activities
	Foreign Exchange Forward Contracts: Although the majority of the Company’s revenue and expense activities are transacted in U.S. dollars, the Company does transact business in foreign countries. The Company’s primary foreign currency cash flows are in Canada and several European countries. In an effort to reduce its foreign currency exposure to Canadian dollar denominated expenses, the Company enters into Canadian dollar forward contracts to hedge the Canadian dollar denominated costs for its manufacturing operation in Canada. The Company does not engage in currency speculation.
	The Company’s Canadian dollar forward contracts in effect as of September 27, 2013 have durations of five to 15 months. These contracts are designated as a cash flow hedge and are considered highly effective. Unrealized gains and losses from foreign exchange forward contracts are included in “accumulated other comprehensive income” in the consolidated balance sheets. At September 27, 2013, the unrealized loss, net of tax, was not material. At September 28, 2012, the unrealized gain, net of tax of $0.3 million, was $0.8 million. Changes in the fair value of foreign currency forward contracts due to changes in time value are excluded from the assessment of effectiveness and are immediately recognized in “general and administrative” expenses in the consolidated statements of comprehensive income (loss). The time value was not material for all periods presented. If the transaction being hedged fails to occur, or if a portion of any derivative is ineffective, then the Company immediately recognizes the gain or loss on the associated financial instrument in “general and administrative” expenses in the consolidated statements of comprehensive income (loss). No ineffective amounts were recognized due to hedge ineffectiveness for fiscal years 2013 and 2012, and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011.
	As of September 27, 2013, the Company had entered into Canadian dollar forward contracts for approximately $43.0 million (Canadian dollars), or approximately 78% of estimated Canadian dollar denominated expenses for October 2013 through September 2014, at an average rate of approximately 0.96 U.S. dollars to one Canadian dollar.
	See Note 5, Financial Instruments, for further information regarding the Company’s derivative instruments.

	b The amount recognized in income during fiscal year 2013 represents $235 gain related to the amount excluded from the assessment of hedge effectiveness. The amount recognized in income during fiscal year 2012 represents $33 loss related to the amount excluded from the assessment of hedge effectiveness, net of a $1 gain related to the ineffective portion of the hedging relationships. The amount recognized in income during the periods of fiscal year 2011 presented represents a $206 and $50 gain, respectively, related to the amount excluded from the assessment of hedge effectiveness.
	As a result of the use of derivative instruments, the Company is exposed to the risk that counterparties to derivative contracts will fail to meet their contractual obligations. The Company does not hold collateral or other security from its counterparties supporting its derivative instruments. To mitigate the counterparty credit risk, the Company has a policy of only entering into contracts with carefully selected major financial institutions based upon their credit ratings and other factors. The Company regularly reviews its credit exposure balances as well as the creditworthiness of its counterparties.
	When the Company’s derivatives are in a net asset position, such as the case with certain of the Company’s forward foreign exchange contract derivatives at September 27, 2013, the Company is exposed to credit loss from nonperformance by the counterparty. If the counterparty fails to perform, credit risk with such counterparty is equal to the extent of the fair value gain in the derivative.

	Commitments and Contingencies
	Leases: The Company is committed to minimum rentals under non-cancelable operating lease agreements, primarily for land and facility space, that expire on various dates through 2050. Certain of the leases provide for escalating lease payments. Future minimum lease payments for all non-cancelable operating lease agreements at September 27, 2013 were as follows:
	Fiscal Year	Operating Leases
	2014	$	1,897
	2015	986
	2016	614
	2017	306
	2018	322
	Thereafter	2,239
		$	6,364
	Real estate taxes, insurance, and maintenance are also obligations of the Company. Rental expense under non-cancelable operating leases amounted to $3.2 million, $3.0 million, $1.8 million and $1.0 million for fiscal years 2013 and 2012, and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011, respectively. Assets subject to capital leases at September 27, 2013 and September 28, 2012 were not material.
	Guarantees: The Company has restricted cash of $2.6 million and $1.9 million as of September 27, 2013 and September 28, 2012, respectively, consisting of bank guarantees from customer advance payments to the Company’s international subsidiaries and cash collateral for certain performance bonds.
	Indemnification: As permitted under Delaware law, the Company has agreements whereby the Company indemnifies its officers, directors and certain employees for certain events or occurrences while the, officer, director or employee is, or was serving, at the Company’s request in such capacity. The term of the indemnification period is for the officer’s, director’s and employee’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has Director and Officer insurance policies that limit its exposure and may enable it to recover a portion of any future amounts paid.
	The Company has entered into other standard indemnification agreements in its ordinary course of business. Pursuant to these agreements, the Company agrees to indemnify, defend, hold harmless and to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with any patent, copyright or other intellectual property infringement claim by any third-party with respect to the Company’s products. The term of these indemnification agreements is generally perpetual after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. Management believes that the likelihood of loss under these agreements is remote.
	Employment Agreements: The Company has entered into employment agreements with certain members of the executive management, which include provisions for the continued payment of salary, benefits and a pro-rata portion of an annual bonus for periods ranging from 12 months to 30 months upon certain terminations of employment.
	Contingencies: From time to time, the Company may be subject to claims that arise in the ordinary course of business. Except as noted below, in the opinion of management, all such matters involve amounts that would not have a material adverse effect on the Company’s consolidated financial position if unfavorably resolved.
	During fiscal year 2011, the Company received a notice from a customer terminating a portion of a sales contract due to alleged nonperformance. The Company has reached a settlement agreement with its customer resolving this matter. In April 2012, the Company’s partner initiated a legal proceeding against the Company in the Commercial Court of Aix-en-Provence, France, originally claiming damages of approximately $3.6 million. The Company recorded certain costs in fiscal year 2011 as a result of the termination. In June 2013, the parties settled the dispute with the Company agreeing to pay its partner a lump sum of a portion of the original claim to settle all disputes between the parties in connection with the partial termination of the sales contract. As a result of the settlement, the Company recorded a gain of $0.7 million in “cost of sales” in the consolidated statement of comprehensive income for fiscal year 2013 due to the reversal of a portion of the liability.
	In fiscal year 2011, the Company submitted a voluntary self-disclosure to the U.S. Office of Foreign Assets Control (“OFAC”) of the U.S. Department of the Treasury regarding assistance provided by the Swiss branch office of one of its U.S. subsidiaries with respect to sales of medical x-ray equipment by its Canadian subsidiary to distributors for resale to end-users in Iran, which is subject to U.S. trade sanctions. In fiscal year 2012, the Company was notified by OFAC that it had determined a penalty was appropriate for the apparent violation. In August 2013, the Company reached a settlement with OFAC and paid a civil penalty of approximately $0.3 million, which the Company recorded in “general and administrative” expenses in the consolidated statement of comprehensive income for fiscal year 2013. OFAC, as a result, agreed to release and forever discharge the Company without any finding of fault from any and all civil liability in connection with the alleged violations under the legal authorities administered by OFAC.
	All legal costs are expensed as incurred.

	In connection with the Merger, in February 2011, the Company entered into an advisory agreement with Veritas Capital Fund Management, L.L.C. (“Veritas Management”), a Delaware limited liability company and an affiliate of Veritas Capital, pursuant to which Veritas Management will provide the Company with certain management, advisory and consulting services including, without limitation, business and organizational strategy, financial and advisory services. The initial term of the advisory agreement will end December 31, 2023, and the agreement will renew automatically for additional one-year terms thereafter unless Veritas Management or the Company terminates the advisory agreement. Pursuant to such agreement, the Company pays Veritas Management an annual fee equal to the greater of $1.0 million or 3.0% of the Company’s Adjusted EBITDA (earnings before net interest expense, provision for income taxes, depreciation and amortization, certain unusual or non-recurring items and certain non-cash items), a portion of which is payable in advance annually, and the Company reimburses certain out-of-pocket expenses of Veritas Management. For fiscal years 2013 and 2012 and the period February 11, 2011 to September 30, 2011, the Company incurred Veritas Management advisory fee expense of $2.2 million, $2.0 million and $1.4 million, respectively, recorded in “general and administrative” expenses in the consolidated statements of comprehensive income (loss).
	If Parent or any of its subsidiaries (including the Company) is involved in any transaction (including, without limitation, any acquisition, merger, disposition, debt or equity financing, recapitalization, structural reorganization or similar transaction), the Company will pay a transaction fee to Veritas Management equal to the greater of $0.5 million or 2.0% of transaction value. Veritas Management waived any transaction fees due for acquisitions made by the Company during fiscal years 2013 and 2012. The Company may terminate the advisory agreement immediately prior to a change of control or an initial public offering, upon payment of an amount equal to all accrued fees and expenses plus the present value of all annual fees that would have been payable under the advisory agreement through December 31, 2023.
	No other related person has any interest in the advisory agreement.
	Certain members of management of the Company have been granted Class B membership interests in Holding LLC. See Note 11 for more details.

	In April 2011 and December 2011, certain members of management and independent directors of the Company were granted Class B membership interests in Holding LLC. At September 27, 2013, the aggregate individual grants of Class B membership interests represented approximately 5.5% of the profit interests in Holding LLC. Pursuant to the terms of the limited liability company operating agreement governing Holding LLC, holders of Class B membership interests are entitled to receive a percentage of all distributions, if any, made by Holding LLC after the holders of the Class A membership interests, including Veritas Capital, have received a return of their invested capital plus an 8% per annum internal rate of return (compounded quarterly and accruing daily) on their unreturned invested capital. Holders of Class B membership interests are not entitled to any voting rights. The Class B membership interests are subject to a five-year vesting schedule, except vesting will be accelerated in the event of a change of control. The unvested portion of Class B membership interests resulting from forfeitures reverts to the holders of Class A membership interests in Holding LLC. Class B membership interests are granted with no exercise price and no expiration date. Grants of Class B membership interests are limited in the aggregate to 7.5% of the net profits interests in Holding LLC.
	A summary of activity for grants and the outstanding balance of Class B membership interests in Holding LLC follow:
		Class B Membership Interests
		Available for Grant			Outstanding			Fair Value at
								Date of Grant
	Balance, September 30, 2011	2.2	%		5.3	%		$	4,874

	Granted	—			—			—
	Balance, September 27, 2013	2	%		5.5	%		$	5,057
	The fair value of grants of Class B membership interests is determined by management using an income approach based on a cash flow methodology, the ownership percentage in Holding LLC, the preference of the Class A membership interests, and a 25% marketability discount. The discount is estimated based on an option pricing model for an Asian put option known as the Finnerty model, and the weighted average assumptions are risk free rate of 0.65%, expected volatility of 75%, restricted period of two years, and no dividend yield.
	The Company records equity-based compensation expense based on the grant-date fair value on a straight-line basis over the vesting period of the awards. The following table summarizes equity-based compensation expense for the periods presented, which was allocated as follows:

	Predecessor’s Stock-based Compensation Plans
	Pursuant to the Merger described in Notes 1 and 3, subject to certain exceptions described below, unvested options to purchase the Predecessor’s common stock became fully vested immediately prior to the effective time of the Merger on February 11, 2011 (“Effective Time”), and at (or, in the case of certain option holders, immediately after) the Effective Time, outstanding unexercised stock options were cancelled in exchange for a cash payment in an amount equal to the product of (x) the number of shares subject to the option and (y) the excess, if any, of (A) $19.50 over (B) the exercise price per share subject to the option, less any applicable taxes. Subject to certain exceptions described below, each share of Predecessor’s restricted stock and each of Predecessor’s restricted stock unit outstanding immediately prior to the Effective Time vested in full and entitled the holder to receive $19.50 in cash, less applicable taxes. With respect to options and restricted stock units granted in the period October 2, 2010 to February 10, 2011, only 25%of such options and restricted stock units became vested upon the closing of the Merger and the remaining 75% were cancelled.
	As a result of the acceleration of the vesting of stock options described above, Predecessor incurred additional stock compensation expense of $3.4 million of which $0.4 million, $0.2 million, $0.4 million and $2.4 million were allocated to cost of sales, research and development, sales and marketing and general and administrative expenses, respectively, in the consolidated statement of comprehensive loss for period October 2, 2010 to February 10, 2011. Successor also recorded stock compensation expense of $5.2 million which represents the amount of cash payments for the unvested portion of the stock awards for which vesting was accelerated. The $5.2 million stock compensation expense is recorded in “strategic alternative transaction expense” in the consolidated statement of comprehensive loss for the period February 11, 2011 to September 30, 2011.
	Unless otherwise stated, information on the Predecessor’s stock-based compensation plans provided below is for periods prior to the Effective Time and reflects the effect of the acceleration of vesting of the stock-based awards on Predecessor’s consolidated statements of comprehensive income (loss).

	The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value of in-the-money options that would have been received by the option holders had all option holders exercised their options at the Predecessor’s closing stock price on the date indicated.
	During the period October 2, 2010 to February 10, 2011, cash received from option exercises was approximately $0.2 million and the total intrinsic value of options exercised was approximately $0.2 million .
	Stock Purchase Plan: Predecessor’s employee stock purchase plan was terminated after the December 31, 2010 purchase. Employees purchased approximately 13,000 shares during the first quarter of fiscal year 2011 for $0.2 million .
	Restricted Stock and Restricted Stock Units: Granted to directors and employees, the restricted stock and restricted stock units, in each case, generally vested over periods of one to four years. Upon vesting, each restricted stock unit was automatically converted into one share of common stock of the Predecessor.
	The following table summarizes activity of Predecessor’s nonvested restricted stock and restricted stock unit awards for the periods presented:
			Number of Shares			Weighted-Average Grant-Date Fair Value Per Share			Aggregate Fair Value*

	* Based on the value of the Company’s stock on the date of the restricted stock unit vesting or acceleration.
	During the period October 2, 2010 to February 10, 2011, Predecessor granted 102,700 restricted stock units with time-vesting criteria to certain of its non-executive employees and 36,000 restricted stock units with performance-vesting criteria to its executive officers. The performance conditions were based on the achievement of specified EBITDA levels over a period of four years. As mentioned above, only 25% of restricted stock units granted during the period October 2, 2010 to February 10, 2011 became vested upon the closing of the Merger and the remaining 75% were cancelled.
	Predecessor settled stock option exercises and restricted stock units with newly issued common shares.
	Valuation and Expense Information
	The fair value of Predecessor’s time-based option awards was estimated on the date of grant using the Black-Scholes model. The Black-Scholes valuation models was developed for use in estimating the fair value of traded options that had no vesting restrictions and were fully transferable and require the input of subjective assumptions, including the expected stock price volatility and estimated option life. Predecessor did not intend to pay dividends and, accordingly, no dividends were assumed in its Black-Scholes calculation. Since Predecessor’s common stock had not been publicly traded for a sufficient time period, the expected volatility was based on a blend of expected volatilities of similar companies and that of Predecessor based on its available historical data. The risk-free rates were based on the U.S. Treasury yield in effect at the time of the grant. Since Predecessor’s historical data was limited, the expected term of time-based options granted was based on integrating historical data with the simplified method for plain vanilla options. The integration of historical data with the simplified method was done by using the actual life for options that had been settled, and a uniform distribution assumption for the options that were still outstanding.
	Stock Options. Assumptions used in the Black-Scholes model to estimate the fair value of time-based option grants are presented below.
		Period
		October 2, 2010 to
		10-Feb-11
	Expected term (in years)	8.14
	Expected volatility	60.9	%
	Dividend yield	—	%
	Risk-free rate	2.6	%
	The weighted-average grant-date fair value of all the options granted during the period October 2, 2010 to February 10, 2011 was $12.65 per share.
	Stock Purchase Plan. Based on the 15% discount received by the employees, the weighted-average fair value of shares issued under the employee stock purchase plan during the first quarter of fiscal year 2011, the final purchase period, was $2.90 per share.
	Restricted Stock and Restricted Stock Units. The fair value of each time-based restricted stock and restricted stock unit award and of each performance-based restricted stock unit award was calculated using the market price of the Company’s common stock on the date of grant. The fair value of each performance-based restricted stock unit award assumed that the relevant performance criteria would be met and the target payout level would be achieved. Compensation cost was adjusted for any subsequent changes in the outcome of performance-related conditions until the award vested.
	The weighted-average estimated fair value of restricted stock and restricted stock units granted during the period October 2, 2010 to February 10, 2011 was $19.33.
	As stock-based compensation expense recognized in the consolidated statements of comprehensive loss for the period October 2, 2010 to February 10, 2011, was based on awards ultimately expected to vest, it was reduced for estimated forfeitures. Forfeitures were estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differed from those estimates.
	The following table summarizes stock-based compensation expense for the period October 2, 2010 to February 10, 2011, which was allocated as follows:
		Period
		October 2, 2010 to
		10-Feb-11
	Share-based compensation cost recognized in the income statement by caption:
	Cost of sales	$	609
	Research and development	320
	Selling and marketing	499
	General and administrative	3,127
		$	4,555
	Share-based compensation cost capitalized in inventory	$	928
	Share-based compensation cost remaining in inventory at end of period	$	416
	Share-based compensation expense by type of award:
	Stock options	$	1,564
	Restricted stock and units	2,948
	Stock purchase plan	43
		$	4,555
	During the period October 2, 2010 to February 10, 2011, the tax benefit realized from option exercises and restricted stock vesting, including those that were accelerated pursuant to the Merger, totaled approximately $5.8 million.

	Effective tax rate	33.2	%		48.1	%		24.2	%			(26.2	)%
	The effective tax rate for the fiscal year ended September 27, 2013 was 33.2% and differs from the federal statutory rate of 35% primarily due to the domestic manufacturing deduction, a prior year change in estimate based on a tax filing and research and development tax credits, partially offset by state income taxes. The 6.3% state tax rate for the fiscal year ended September 27, 2013 includes discrete tax charges of 2.7% for tax rate changes.
	The effective tax rate for the fiscal year ended September 28, 2012 was 48.1% and differs from the federal statutory rate of 35% primarily due to state income taxes, foreign earnings that are subject to U.S. federal income tax, tax contingency reserves, non-deductible stock compensation expense, partially offset by the domestic manufacturing deduction. The 7.9% state tax rate for the fiscal year ended September 28, 2012 includes discrete tax charges of 2.8% for tax rate changes and 2.0% for a change in estimate based on a tax return filing.
	The effective tax rate for the period February 11, 2011 to September 30, 2011 was 24.2% and differs from the federal statutory rate of 35% primarily due to the incremental tax on foreign earnings that are subject to U.S. federal income taxes, non-deductible Merger expenses and the true-up of prior year research and development tax credits; partially offset by a reduction of tax contingency reserves. The effective tax rate for the period October 2, 2010 to February 10, 2011 was a negative 26.2% and differs from the federal statutory rate of 35% primarily due to non-deductible Merger expenses and the incremental tax on foreign earnings that are subject to U.S. federal income taxes and foreign tax rate differences that increased income tax expense, which on a combined basis decreased the effective tax rate benefit by approximately 67%.
	Deferred income taxes reflect the net tax effects of temporary differences between the basis of assets and liabilities for financial reporting and income tax purposes. The Company’s deferred tax assets (liabilities) were as follows:
		September 27,				September 28,
		2013				2012
	Deferred tax assets:
	Inventory and other reserves	$	9,059			$	9,053
	Accrued vacation	2,194				2,190
	Deferred compensation and other accruals	1,201				645
	Tax credit carryforward	1,096				7,894
	Net operating loss carryforward	921				1,406
	Other deferred tax assets	210				216
	Gross deferred tax assets	14,681				21,404
	Valuation allowance	—				—
	Total deferred tax assets	$	14,681			$	21,404
	Deferred tax liabilities:
	Accelerated depreciation	$	(14,789	)		$	(16,386	)
	Acquisition-related intangibles	(74,901		)		(77,234		)
Unremitted foreign earnings	(127		)		(1,989		)
Other deferred tax liabilities	(595		)		(668		)
Total deferred tax liabilities	$	(90,412	)		$	(96,277	)
Net deferred tax liabilities	$	(75,731	)		$	(74,873	)
Realization of the Company’s net deferred tax assets is based upon the weight of available evidence, including such factors as recent earnings history and expected future taxable income. The Company believes it is more likely than not that such assets will be realized; however, ultimate realization could be negatively impacted by market conditions and other variables not known or anticipated at this time. As of September 27, 2013, the Company had federal foreign tax credit carryforwards of $1.0 million. If not utilized, the federal foreign tax credit carryforwards will begin to expire in 2017.
At September 27, 2013, the Company had state net operating loss carryforwards of approximately $15.7 million. The state net operating loss carryovers will begin to expire in 2026, if not utilized.
The Company has not provided deferred taxes on approximately $7.5 million of the Company’s undistributed earnings in its Canadian operations which are permanently reinvested.
The Internal Revenue Code imposes limitations on the utilization of net operating loss and credit carryforwards in the event of an “ownership change” for tax purposes, as defined in Section 382 of the Internal Revenue Code. The Section 382 Limitation is an annual limitation on the amount of pre-ownership change NOLs that a corporation may use to offset its post-ownership change income. In June 2012, the Company acquired the stock of Locus Microwave Inc. as part of its acquisition of Codan Satcom. Locus Microwave had approximately $4.6 million in net operating loss carryforwards, but none of these losses were available to the Company due to limitations under Internal Revenue Code Section 382; therefore, Locus Microwave net operating loss carryforwards were not recorded as deferred tax assets.
The net deferred tax liabilities were classified in the consolidated balance sheets as follows:
	September 27,				September 28,
	2013				2012
Deferred tax assets:
Current	$	13,486			$	14,186
Noncurrent (other long-term assets)	—				114
Deferred tax liabilities:
Current (accrued expenses)	(39		)		(294		)
Noncurrent	(89,178		)		(88,879		)
Net deferred tax liabilities	$	(75,731	)		$	(74,873	)
The total unrecognized tax benefits, excluding any related interest accrual, are reported in the consolidated balance sheets in the following accounts:
	September 27,				September 28,
	2013				2012
Income taxes payable	$	2,074			$	2,215
Other long-term liabilities	3,823				3,511
	$	5,897			$	5,726
In anticipation of a tax assessment from Canada Revenue Authority (“CRA”) to settle a transfer pricing audit on the sale of the Satcom Division to its Canadian subsidiary in fiscal years 2001 and 2002, the Company prepaid the expected tax liability. At September 27, 2013, the $3.3 million unrecognized tax benefit amount is fully offset by the tax prepayment, resulting in a net reported current income tax liability for unrecognized tax benefits of zero for this item in the consolidated balance sheet.
All of the unrecognized tax benefit balances of $5.9 million and $5.7 million would reduce the effective tax rate if recognized as of September 27, 2013 and September 28, 2012, respectively. The Company believes that it is reasonably possible that, in the next 12 months, the amount of unrecognized tax benefits related to the resolution of federal, state and foreign matters could be reduced by $5.3 million as audits close, statutes expire and tax payments are made. As of September 27, 2013, the Company had accrued income tax related interest and penalties of approximately $1.4 million. Estimated interest and penalties related to the underpayment of income taxes are classified as a component of tax expense in the consolidated statements of comprehensive income (loss) and totaled approximately $0.1 million for the fiscal year ended September 27, 2013. The Company has minimal penalties accrued in income tax expense. Any prospective adjustments to the Company’s unrecognized tax benefits will be recorded as an increase or decrease to income tax expense and cause a corresponding change to the Company’s effective tax rate. Accordingly, the Company’s effective tax rate could fluctuate materially from period to period. If the accrued interest and penalties do not ultimately become payable, amounts accrued will be reduced in the period that such determination is made and reflected as a reduction to income tax expense.
A reconciliation of the beginning and ending balances of the total amount of unrecognized tax benefits, excluding accrued interest and penalties, is as follows:
	Year Ended
	September 27,				September 28,
	2013				2012
Beginning of period balance	$	5,726			$	6,904
Additions based on tax positions related to the current period	183				52
Reductions for expiration of statute of limitations	—				—
Additions for tax positions of prior periods	97				31
Reductions for tax positions of prior periods	(109		)		(1,261		)
End of period balance	$	5,897			$	5,726
The Company files a U.S. federal income tax return and state income tax returns in California, Massachusetts and several other U.S. states. The Company also files income tax returns in Canada and other foreign jurisdictions. With the exception of Canada and California, the Company is no longer subject to examination by the various taxing authorities for fiscal years prior to 2009. The Company’s Canadian subsidiary is no longer subject to examination by the taxing authorities for fiscal years prior to 2003. The Company has income tax audits in progress in several jurisdictions in which it operates, including an audit by the CRA for fiscal year 2010 and for the periods from October 2, 2010 to February 10, 2011 and February 11, 2011 to September 30, 2011.
During fiscal year 2013, the Company received a $4.6 million refund from the Internal Revenue Service (“IRS”) in settlement of a transfer pricing audit on the sale of the Satcom Division to its Canadian subsidiary in fiscal years 2001 and 2002. The IRS refund was recorded as a reduction to income tax receivable (prepaid and other current assets). During fiscal year 2012, the Company received a refund of $2.4 million in settlement of the transfer pricing audit, previously noted, with CRA for fiscal years 2001 and 2002. The CRA refund was recorded as a $1.8 million reduction to long-term assets, a $0.5 million increase in the balance of uncertain tax benefits and a tax benefit of $0.1 million. During fiscal year 2012, the company completed an audit with the IRS for fiscal years 2008 and 2009 and received a tax assessment of approximately $17,000.
Based on the outcome of tax examinations of the Company and the result of the expiration of statutes of limitations for specific jurisdictions, it is reasonably possible that the related unrecognized tax benefits could change from those recorded in the statement of financial position. The Company has provided for amounts of anticipated tax audit adjustments in various jurisdictions based on its reasonable estimate of additional taxes and interest that do not meet the more likely than not standard under the accounting guidance for uncertainty in income taxes.

Segment Reporting Disclosure	'
	Segments, Geographic and Customer Information
	The Company’s reportable segments are electron devices and satcom equipment. The electron devices segment develops, manufactures and distributes high-power/high-frequency microwave and RF signal components. The satcom equipment segment manufactures and supplies high-power amplifiers and networks for satellite communication uplink, electronic warfare and industrial applications. Segment information reported below is consistent with the manner in which it is reviewed and evaluated by the Company’s chief operating decision maker (“CODM”), its chief executive officer, and is based on the nature of the Company’s operations and products offered to customers.
	The Company’s reportable segments, electron devices and satcom equipment, are differentiated based on their underlying profitability and economic performance. The electron devices segment is made up of four divisions, that have been aggregated based on the similarity of their economic characteristics as measured by EBITDA, and the similarity of their products and services, production processes, types of customers and distribution methods, and nature of regulatory environments. The satcom equipment segment consists of one division. The Company’s analysis of the similarity of economic characteristics was based on both a historical and anticipated future analysis of performance.
	The electron devices segment develops, manufactures and distributes high power/high frequency microwave and RF signal components. These products are used in the communication, radar, electronic countermeasures, industrial, medical and scientific markets depending on the specific power and frequency requirements of the end-user and the physical operating conditions of the environment in which the electron devices will be located. These products are distributed through the Company’s direct sales force, independent sales representatives and distributors.
	The satcom equipment segment manufactures and supplies high-power amplifiers and networks for satellite communication uplink and industrial applications. This segment also provides spares, service and other post-sales support. Its products are distributed through the Company’s direct sales force and independent sales representatives.
	Amounts not reported as electron devices or satcom equipment are reported as “other.” Other includes the activities of the Company’s Malibu Division and unallocated corporate expenses, such as business combination-related expenses, share-based compensation expense and certain non-recurring or unusual expenses. The Malibu Division is a designer, manufacturer and integrator of advanced antenna systems for radar, radar simulators and telemetry systems, as well as for data links used in ground, airborne, unmanned aerial vehicles (“UAVs”) and shipboard systems.
	Sales and marketing, and certain administration expenses, are allocated to the divisions and are included in the results reported. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment product transfers are recorded at cost.

	EBITDA represents earnings before net interest expense, provision for income taxes and depreciation and amortization. The Company believes that EBITDA is useful to assess its ability to generate cash from operations sufficient to pay taxes, to service debt and to undertake capital expenditures.
	For the reasons listed below, the Company believes that U.S. generally accepted accounting principles (“GAAP”)-based financial information for leveraged businesses like its own should be supplemented by EBITDA so that investors better understand its financial performance in connection with their analysis of the Company’s business:
	•	EBITDA is a component of the measures used by the Company’s board of directors and management team to evaluate the Company’s operating performance;
	•	the Company’s Senior Credit Facilities contain covenants that require the Company to maintain a total leverage ratio and an interest coverage ratio that contain EBITDA as a component, and the Company’s management team uses EBITDA to monitor compliance with these covenants;
	•	EBITDA is a component of the measures used by the Company’s management team to make day-to-day operating decisions;
	•	EBITDA facilitates comparisons between the Company’s operating results and those of competitors with different capital structures and, therefore, is a component of the measures used by the management to facilitate internal comparisons to competitors’ results and the Company’s industry in general; and
	•	the payment of management bonuses is contingent upon, among other things, the satisfaction by the Company of certain targets that contain EBITDA as a component.
	EBITDA is not a presentation made in accordance with U.S. GAAP and has important limitations as an analytical tool. EBITDA should not be considered as an alternative to net income (loss), operating income or any other performance measures derived in accordance with U.S. GAAP as a measure of operating performance or operating cash flows as a measure of liquidity. The Company’s use of the term EBITDA varies from others in the Company’s industry. The Company’s presentation of EBITDA should not be construed to imply that the Company’s future results will be unaffected by unusual or non-recurring items. Operating income by the Company’s reportable segments was as follows:

	Subsequent Event
	On October 1, 2013, the Company completed its purchase of the outstanding stock of Radant Technologies, Inc. (“Radant”), a Massachusetts corporation, for a payment of approximately $36.0 million in cash, subject to post-closing adjustments based on a determination of Radant's closing net working capital. A maximum of $10.0 million in potential additional payments may be payable if certain financial targets are achieved over the next two years. Radant designs, manufactures and tests advances composite radomes, reflector antennas and structures for defense aerospace and naval applications as well as commercial aerospace applications. The acquisition of Radant provides the Company with advanced technology and specialized products for radar, electronic warfare and communications applications that complement and extend the Company's broad portfolio of microwave, RF, power and control solutions for these and other critical applications.
	The Company will record the acquisition of Radant using the acquisition method of accounting and will recognize the assets acquired and liabilities assumed at their fair values as of the date of the acquisition. The Company is currently finalizing the purchase price for Radant and evaluating the fair values of the assets acquired and liabilities assumed and expects to complete its purchase price allocation in fiscal year 2014.

	Supplemental Guarantors Condensed Consolidating Financial Information
	The tables that follow reflect the supplemental guarantor financial information associated with CPII’s 8% Notes issued on February 11, 2011. The 8% Notes are guaranteed by Parent and, subject to certain exceptions, each of Parent’s existing and future domestic restricted subsidiaries (other than CPII) on a senior unsecured basis. Separate financial statements of the guarantors are not presented because (i) the guarantors are wholly owned and have fully and unconditionally guaranteed the 8% Notes on a joint and several basis and (ii) CPII’s management has determined that such separate financial statements are not material to investors. Instead, presented below are the consolidating financial statements of: (a) the guarantor subsidiaries (all of the domestic subsidiaries), (b) the non-guarantor subsidiaries, (c) the consolidating elimination entries, and (d) the consolidated totals. The accompanying consolidating financial information should be read in connection with the consolidated financial statements of the Company.
	Investments in subsidiaries are accounted for based on the equity method. The principal elimination entries eliminate investments in subsidiaries, intercompany balances, intercompany transactions and intercompany sales.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Foreign Currency Translation	'
	Foreign Currency Translation:    The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Gains or losses resulting from the translation into U.S. dollars of amounts denominated in foreign currencies are included in the determination of net income or loss. Foreign currency translation gains and losses are generally reported on a net basis in the caption “general and administrative” in the consolidated statements of comprehensive income (loss), except for translation gains or losses on income tax-related assets and liabilities, which are reported in “income tax expense” in the consolidated statements of comprehensive income (loss).
Use of Estimates	'
	Use of Estimates:    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of sales and costs and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition; inventory valuation; recoverability and valuation of recorded amounts of long-lived assets and identifiable intangible assets, including goodwill; recognition and measurement of current and deferred income tax assets and liabilities; and business combinations. The Company bases its estimates on various factors and information, which may include, but are not limited to, history and prior experience, experience of other enterprises in the same industry, new related events, current economic conditions and information from third-party professionals that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Revenue Recognition	'
	Revenue Recognition:    Sales are recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. The Company’s products are generally subject to warranties, and the Company provides for the estimated future costs of repair, replacement or customer accommodation in cost of sales.
	Revenue arrangements that include multiple deliverables are divided into separate units of accounting if the deliverables meet certain criteria. The Company allocates the consideration among the separate units of accounting based on their relative selling prices, and considers the applicable revenue recognition criteria separately for each of the separate units of accounting. The Company applies a selling price hierarchy for determining the selling price of a deliverable in a sale arrangement. The selling price for each deliverable is based on vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) if VSOE is not available, or estimated selling price if neither VSOE or TPE is available.
	The Company has commercial and U.S. Government fixed-price contracts that are accounted for under the accounting guidance for construction-type and production-type contracts. These contracts have represented not more than 4% of the Company’s sales during fiscal years 2013 and 2012 and each of the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011, and are for contracts that generally are greater than one year in duration and that include a significant amount of product development. The Company uses the percentage-of-completion method when reasonably dependable estimates of the extent of progress toward completion, contract revenues and contract costs can be made. The portion of revenue earned or the amount of gross profit earned for a period is determined by measuring the extent of progress toward completion using total cost incurred to date and estimated costs at contract completion.
	Sales under cost-reimbursement contracts, which are primarily for research and development, are recorded as costs are incurred and include estimated earned fees in the proportion that costs incurred to date bear to total estimated costs. The fees under certain commercial and U.S. Government contracts may be increased or decreased in accordance with cost or performance incentive provisions that measure actual performance against established targets or other criteria. Such incentive fee awards or penalties are included in revenue at the time the amounts can be reasonably determined.
	Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents:  The Company considers all highly liquid short-term investments with original maturities of three months or less, readily convertible to known amounts of cash to be cash equivalents.
Restricted Cash	'
	Restricted Cash:  Restricted cash consists of bank guarantees from customer advance payments to the Company’s international subsidiaries and cash collateral for certain performance bonds. The bank guarantees become unrestricted cash when performance under the sales or supply contract is complete. The cash collateral for the performance bonds becomes unrestricted cash when the performance bonds expire.
Inventories	'
	Inventories:  Inventories are stated at the lower of average cost or market value. The Company uses a combination of standard cost and moving weighted-average cost methodologies to determine the cost basis for its inventories, approximating a first-in, first-out basis. Costs include labor, material and overhead costs. Overhead costs are based on indirect costs allocated among cost of sales, work-in-process inventory and finished goods inventory. Inventories also include costs and earnings in excess of progress billings for contracts using the percentage-of-completion method of accounting. Progress billings in excess of costs and earnings for contracts using the percentage-of-completion method of accounting are reported in Advance Payments from Customers.
	The Company assesses the valuation of inventory and periodically writes down the value for estimated excess and obsolete inventory based upon actual usage and estimates about future demand. The excess balance determined by this analysis becomes the basis for the Company’s excess inventory charge. Management personnel play a key role in the excess inventory review process by providing updated sales forecasts, managing product rollovers and working with manufacturing to maximize recovery of excess inventory. If actual market conditions are less favorable than those projected by management, additional write-downs may be required. If actual market conditions are more favorable than anticipated, inventory previously written down may be sold, resulting in lower cost of sales and higher income from operations than expected in that period.
	Management also reviews the carrying value of inventory for lower of cost or market on an individual product or contract basis. A loss is charged to cost of sales when known if estimated product or contract cost at completion is in excess of net realizable value (selling price less estimated cost of disposal). If actual product or contract cost at completion is different than originally estimated, then a loss or gain provision adjustment is recorded that would have an impact on the Company’s operating results.
Property, Plant and Equipment	'
	Property, Plant and Equipment:    Property, plant and equipment are stated at cost. Major improvements are capitalized, while maintenance and repairs are expensed as incurred. Plant and equipment are depreciated over their estimated useful lives using the straight-line method. Building, land improvements and process equipment are depreciated generally over 25, 20 and 12 years, respectively. Machinery and equipment are depreciated generally over seven to 12 years. Office furniture and equipment are depreciated generally over five to 10 years. Leasehold improvements are amortized using the straight-line method over their estimated useful lives, or the remaining term of the lease, whichever is shorter.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets:    The Company accounts for business combinations using the purchase method of accounting in which intangible assets acquired are recognized and reported apart from goodwill.
	The values assigned to acquired identifiable intangible assets for technology were determined based on the excess earnings method of the income approach. This method determines fair market value using estimates and judgments regarding the expectations of future after-tax cash flows from those assets over their lives, including the probability of expected future contract renewals and sales, all of which are discounted to their present value.
	Goodwill and identifiable intangible assets with indefinite useful lives are tested for impairment at least annually. Intangible assets subject to amortization are amortized over their respective estimated useful lives and reviewed for impairment. Identifiable intangible assets are amortized on a straight-line basis over their useful lives of up to 40 years. The Company tests goodwill for impairment annually or more frequently if events and circumstances warrant. The Company’s annual testing resulted in no impairment of goodwill in fiscal years 2013 and 2012 and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011.
Long-Lived Assets	'
	Long-Lived Assets:    Long-lived and finite-lived intangible assets, including property, equipment and leasehold improvements, are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when the sum of the undiscounted future net cash flows expected to result from the use of the asset and its eventual disposition is less than its carrying amount. Such impairment loss would be measured as the difference between the carrying amount of the asset and its fair value.
	There were no triggering events identified that would indicate a need to review for impairment of long-lived assets during fiscal years 2013 and 2012 and the periods February 11, 2011 to September 30, 2011 and October 2, 2010 to February 10, 2011.
Deferred Debt Issue Costs	'
	Deferred Debt Issue Costs:    Costs incurred related to the issuance of the Company’s long-term debt and other credit facilities are capitalized and amortized over the estimated time the obligations are expected to be outstanding using the effective interest method. Deferred debt issue costs for CPII’s revolving credit facility, term loan and 8% Senior Notes due 2018 are amortized over the term to maturity of the respective debt of five years, six years and seven years, respectively.
Product Warranty	'
	Product Warranty:    The Company’s products typically carry warranty periods of one to three years or warranties over a predetermined product usage life. The Company estimates the costs that may be incurred under its warranty plans and records a liability in the amount of such estimated costs at the time revenue is recognized. The determination of product warranty reserves requires the Company to make estimates of product return rates and expected cost to repair or replace the products under warranty. The Company assesses the adequacy of its preexisting warranty liabilities and adjusts the balance based on actual experience and changes in future expectations.
Business Risks and Credit Concentrations	'
	Business Risks and Credit Concentrations:    Defense-related applications, such as certain radar, electronic countermeasures and military communications applications, constitute a significant portion of the Company’s sales. Companies engaged in supplying defense-related equipment and services to government agencies are subject to certain business risks unique to that industry. Sales to the government may be affected by changes in procurement policies, budget considerations, changing concepts of national defense, political developments abroad and other factors.
Research and Development	'
	Research and Development: Company-sponsored research and development costs related to both present and future products are expensed as incurred. Customer-sponsored research and development costs are charged to cost of sales to match revenue recognized.
Advertising Expenses	'
	Advertising Expenses:  Costs related to advertising are recognized in selling and marketing expenses as incurred. Advertising expenses were not material in any of the periods presented.
Income Taxes	'
	Income Taxes:    The Company records income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company recognizes liabilities for uncertain tax positions based on the two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Such a change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.
	Income tax-related interest expense or income, foreign exchange gains and losses and penalties are reported as components of the provision for income taxes in the consolidated statements of comprehensive income (loss).
Comprehensive Income	'
	Comprehensive Income:    Comprehensive income is defined as a change in equity of a company during a period from transactions and other events and circumstances, excluding transactions resulting from investments by owners and distributions to owners. The difference between net income and comprehensive income for the Company arises from unrealized gains and losses on cash flow hedge contracts, net of tax, and unrealized actuarial gains and losses and prior service costs and credits for pension liability, net of tax.
