Defense contract audit agency completed cost audits	Contract costs on U.S. government contracts are subject to audit and review by the Defense Contracting Management Agency (DCMA), the Defense Contract Audit Agency (DCAA), and other U.S. government agencies, as well as negotiations with U.S. government representatives. The Company’s incurred cost audits by the DCAA have not been concluded for fiscal year 2004 and subsequent fiscal years. Although the Company has recorded contract revenues subsequent to fiscal year 2003 based upon an estimate of costs that the Company believes will be approved upon final audit or review, the Company does not know the outcome of any ongoing or future audits or reviews and adjustments, and if future adjustments exceed the Company’s estimates, its profitability would be adversely affected.

Accounting Standards Update No 2011-11 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements	In December 2011, the FASB issued ASU 2011-11, Balance Sheet (ASC 210): Disclosures about offsetting Assets and Liabilities. The new authoritative guidance requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including the effect or potential effect of rights of setoff associated with certain financial instruments and derivative instruments in the scope of this authoritative guidance. This authoritative guidance became effective for the Company beginning in the first quarter of fiscal year 2014 and has been applied retrospectively for all comparative periods presented. Adoption of this authoritative guidance did not have a material impact on the Company’s consolidated financial statements and disclosures.
Accounting Standards Update 2012-02 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements	In July 2012, the FASB issued ASU 2012-02, Intangibles—Goodwill and Other (ASC 350): Testing Indefinite-Lived Intangible Assets for Impairment. The new authoritative guidance simplifies the requirements for testing for indefinite-lived intangible assets other than goodwill and permits an entity to first assess qualitative factors to determine whether it is necessary to perform a quantitative fair value test. This authoritative guidance became effective for the Company during fiscal year 2014. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements and disclosures.
Accounting Standards Update 2013-02 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements	In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (ASC 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The guidance, which became effective for the Company beginning in the first quarter of fiscal year 2014, required changes in presentation only and the adoption of this standard did not have a significant impact on the Company’s consolidated financial statements and disclosures. The Company considers information related to amounts reclassified out of accumulated other comprehensive income to be insignificant and therefore immaterial for separate disclosures.
Accounting Standards Update 2013-05 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements	In March 2013, the FASB issued ASU 2013-05, Foreign Currency Matters (ASC 830): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. ASU 2013-05 clarifies that the cumulative translation adjustment should be released into net income only when a reporting entity ceases to have a controlling financial interest in a subsidiary or a business within a foreign entity. Further, for an equity method investment that is a foreign entity, a pro rata portion of the cumulative translation adjustment should be released into net income upon a partial sale of such an equity method investment. These amendments are to be applied prospectively to derecognition events occurring after the effective date. This guidance is effective for the Company beginning in the first quarter of fiscal year 2015 and the adoption of this standard is not expected to have a material impact on its consolidated financial statements and disclosures.
Accounting Standards Update No 2013-11 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements	In July 2013, the FASB issued ASU 2013-11, Income Taxes (ASC 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 requires the netting of unrecognized tax benefits against available deferred tax assets for losses and other carryforward benefits that would be available to offset the liability for uncertain tax positions rather than presenting the unrecognized tax benefits on a gross basis. This guidance is effective for the Company beginning in the first quarter of fiscal year 2015 and the adoption of this standard is not expected to have a material impact on its consolidated financial statements and disclosures.
Accounting Standards Update No 2014-08 [Member]
Company And Summary Of Significant Accounting Policies [Line Items]
Description of new accounting pronouncements	In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU 2014-08 limits the requirement to report discontinued operations to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. The amendments also require expanded disclosures concerning discontinued operations and disclosures of certain financial results attributable to a disposal of a significant component of an entity that does not qualify for discontinued operations reporting. These amendments are effective prospectively for reporting periods beginning on or after December 15, 2014, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements and disclosures.
