	Business and Basis of Presentation
	Sparton Corporation and subsidiaries (the “Company” or “Sparton”) has been in continuous existence since 1900. It was last reorganized in 1919 as an Ohio corporation. The Company is a provider of complex and sophisticated electromechanical devices with capabilities that include concept development, design and manufacturing engineering, production, distribution, and field service. The Company serves the Medical & Biotechnology, Military & Aerospace and Industrial & Commercial markets through three reportable business segments; Medical Device (“Medical”), Complex Systems (“CS”) and Defense & Security Systems (“DSS”). Financial information by segment is presented in Note 16. All of the Company's facilities are registered to ISO standards, including 9001 or 13485, with most having additional certifications. The Company's products and services include products for Original Equipment Manufacturers (“OEM”) and Emerging Technology (“ET”) customers that are microprocessor-based systems that include transducers, printed circuit boards and assemblies, sensors, and electromechanical components, as well as development and design engineering services relating to these product sales. Sparton also develops and manufactures sonobuoys, anti-submarine warfare (“ASW”) devices used by the United States Navy and other free-world countries. Many of the physical and technical attributes in the production of sonobuoys are similar to those required in the production of the Company's other electrical and electromechanical products and assemblies.
	The unaudited condensed financial statements and related footnotes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The financial information presented herein should be read in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2013, which includes information and disclosures not presented herein. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications of prior period amounts have been made to conform to the current year presentation. Subsequent events have been evaluated through the date these financial statements were issued. In the opinion of management, the unaudited condensed consolidated financial statements contain all of the adjustments, consisting of normal recurring adjustments, necessary to present fairly, in summarized form, the consolidated financial position, results of operations and cash flows of the Company. The results of operations for the three months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the full fiscal year 2014.

Change in Accounting Principle	'
	Change in Accounting Principle
	In the first quarter of fiscal 2014, the Company voluntarily changed its revenue recognition policy related to DSS sonobuoy sales to the U.S. Navy and foreign government customers under long-term contracts that require lot acceptance testing. The new policy continues to recognize revenue under the percentage of completion method, but changes the measurement of progress under these contracts from a completed units accepted basis (whereby revenue was recognized for each lot of sonobuoys produced when that lot was formally accepted by the customer) to a units-of-production basis (whereby revenue is recognized when production and internal testing of each lot of sonobuoys is completed). The Company now has significant experience in producing sonobuoys to customer specifications and internal testing to assess compliance with those specifications and, as such, now has an adequate history of continuous customer acceptance of all sonobuoys produced. Accordingly, the Company believes the new method is preferable primarily because it eliminates delays in revenue and related cost of goods sold recognition due to timing of customer testing and acceptance delays. Such delays commonly occur due to customer circumstances that are unrelated to the product produced. Under the new policy, the revenue and related costs of goods sold of these manufactured sonobuoy lots will more closely match the period in which the product was produced and the related revenue earned, thereby better reflecting the economic activity of the DSS segment. Additionally, this new method provides better matching of periodic operating expenses incurred during production.
	For the three months ended September 30, 2013, this change in accounting policy increased DSS and consolidated net sales and gross profit by $2.2 million and $1.0 million, respectively, and basic and diluted income per share each by $0.07. The following tables present the effects of the retrospective application of this voluntary change in accounting principle (Dollars in thousands, except share amounts):

	New Accounting Standards
	In July 2013, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance under Accounting Standards Update No. 2013-11 ("ASU 2013-11"), which provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss (“NOL”) carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This accounting standard update requires entities to assess whether to net the unrecognized tax benefit with a deferred tax asset as of the reporting date. ASU 2013-11 will be effective for the Company’s first quarter of fiscal 2015. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

	Acquisitions
	Aydin Displays, Inc. — On August 30, 2013, the Company completed the acquisition of certain assets and liabilities related to the contract manufacturing business of Aydin Displays, Inc. ("Aydin Displays" or “Aydin”) in a $15.0 million all-cash transaction, subject to certain post-closing adjustments and financed through the use of borrowings under the Company's Credit Facility. At September 30, 2013, the Company has recorded additional estimated contingent consideration of accounts receivable of $0.4 million in relation to a post-closing working capital adjustment, which is expected to be settled in the second quarter of the Company's fiscal 2014 year. Additional acquisition consideration of up to $6.6 million is contingent upon Aydin attaining certain performance thresholds during the twelve month period following the transaction. The transaction includes an approximate $1.2 million escrowed holdback which is available to fund the working capital adjustment and potential seller indemnification obligations in relation to the acquisition agreement.
	The acquired business, which will be part of the Company's DSS segment and which is expected to add $18 million (unaudited) in annualized revenue, develops enhanced flat panel display and touch-screen solutions with application-critical performance criteria including ruggedization, high resolution, color accuracy, response/refresh times, sunlight readability and other criteria such as magnetic interference and emanations security for the Military & Aerospace and Civil Marine markets. These products are currently specified in the U.S. Navy P8A Poseidon ASW aircraft behind-the-cockpit control center, the command and control centers of many U.S. Navy ships, Federal Aviation Administration air traffic control systems, and cockpit command centers for various civil marine applications. The acquired business will continue to operate as Aydin Displays.
	The Company is in the process of obtaining valuations of certain tangible and intangible assets and liabilities and expects to complete the purchase price allocation in fiscal year 2014 after these valuations are finalized. The following table represents the preliminary allocation of the total consideration to assets acquired and liabilities assumed in the acquisition of Aydin based on Sparton’s preliminary estimate of their respective fair values (in thousands):
	Total purchase consideration:
	Cash	$	15,000
	Estimated additional consideration payable for post-closing working capital adjustment	357
	Total purchase consideration	$	15,357
	Assets acquired and liabilities assumed:
	Accounts receivable, net	$	4,237
	Inventory	8,025
	Other current assets	192
	Property, plant and equipment	374
	Goodwill	4,000
	Other long-term assets	1
	Accounts payable	(1,215		)
	Other current liabilities	(257		)
	Total assets acquired and liabilities assumed	$	15,357
	Total purchase consideration has been preliminarily allocated to the tangible assets acquired and liabilities assumed based on their provisionally estimated fair values at the acquisition date. Additional acquisition consideration of up to $6.6 million is contingent upon Aydin attaining certain performance thresholds. The Company has provisionally assigned no fair value to this contingent liability. It is possible that acquired assets may additionally include customer relationships, the Aydin Displays trade name, unpatented technology and a favorable lease acquired in the transaction. The Company was unable at September 30, 2013 to assign provisionally estimated fair values to these potential assets. The Aydin acquisition has preliminarily resulted in approximately $4 million of goodwill, which will be adjusted downward or upward based on the final values assigned to all acquired assets and liabilities. The Company believes that any goodwill remaining after the valuations are finalized will primarily relate to strategic fit, resulting synergies and the acquired workforce that this business brings to existing operations. Goodwill associated with this acquisition is expected to be deductible for tax purposes and has been assigned entirely to the Company’s DSS segment.
	Included in the Company’s Condensed Consolidated Statements of Operations for the three months ended September 30, 2013 are net sales of approximately $1.2 million and loss before benefit from income taxes of less than $0.1 million, resulting from the acquisition of Aydin since August 30, 2013.
	The Company incurred legal, professional and other costs related to this acquisition aggregating approximately $0.2 million. These costs were recognized as selling and administrative expenses in the three months ended September 30, 2013.
	A portion of Aydin's revenue is derived from contracts to manufacture video displays and other related products to a buyer’s specification under long-term contracts. Revenue and profit is recognized under these contracts using the percentage of completion method based on the ratio of costs incurred to estimated total costs at completion.
	Creonix, LLC — On June 6, 2013, the Company completed the acquisition of certain assets related to the contract manufacturing business of Creonix, LLC (“Creonix”) in a $2.1 million all-cash transaction, subject to certain post-closing adjustments and financed through the use of borrowings under the Company's credit facility. At September 30, 2013, the Company has recognized accounts receivable of $0.1 million as consideration to be returned in relation to a post-closing working capital adjustment, which will be settled in the second quarter of the Company's fiscal 2014 year. The transaction includes an approximate $0.3 million escrowed holdback which is available to fund the working capital adjustment and potential seller indemnification obligations in relation to the acquisition agreement.
	The acquired business, which is reported in the Company's Complex Systems segment, provides the Company with the capability of cable and wire harness engineering and assembly. Additionally, the acquisition provides further expansion into the Industrial and Military & Aerospace markets, diversifies Sparton's customer base and increases utilization of the Company's existing assets through the expected consolidation of this business into Complex Systems's Brooksville, Florida plant during the first six months of fiscal 2014. Creonix primarily manufactures products and components for battery monitoring, high speed optical imaging, neuromuscular incapacitation, imaging and wiring assemblies for military applications, and electrical grid transformer protection systems.
	During the three months ended September 30, 2013, the Company finalized the inventory adjustment under the Creonix asset purchase agreement resulting in a decrease in the previously recorded related receivable from the seller. This measurement period increase in total purchase consideration resulted in the retrospective elimination of the previously recognized gain on acquisition recorded in the fourth quarter of fiscal 2013 of less than $0.1 million and resulting in the recognition of approximately $0.1 million of goodwill. The Company's June 30, 2013 balance sheet has been restated to reflect this adjustment. The following table presents the final allocation of the total consideration to assets acquired and liabilities assumed from Creonix based on Sparton’s estimate of their respective fair values (in thousands):
	Total purchase consideration:
	Cash	$	2,100
	Accounts receivable recognized in relation to inventory adjustment	(105		)
	Total purchase consideration	$	1,995

	Industrial Revenue Bonds
	In connection with its acquisition of Astro in May 2006, the Company assumed repayment of principal and interest on bonds originally issued to Astro by the State of Ohio. These bonds are Ohio State Economic Development Revenue Bonds, series 2002-4. Astro originally entered into the loan agreement with the State of Ohio for the issuance of these bonds to finance the construction of the Company’s Ohio operating facility. The principal amount, including premium, was issued in 2002 and totaled approximately $2.9 million. These bonds have interest rates which vary, dependent on the maturity date of the bonds ranging from 5.00% to 5.45%. Due to an increase in interest rates since the original issuance of the bonds, a discount amounting to approximately $0.2 million on the date of assumption by Sparton was recorded.
	The bonds carry certain sinking fund requirements generally obligating the Company to make monthly deposits of one twelfth of the annual obligation plus accrued interest. The purchase discount is being amortized ratably over the remaining term of the bonds. The Company also has an irrevocable letter of credit in the amount of approximately $0.3 million, which is renewable annually, to secure repayment of a portion of the bonds.
	Short-term debt at September 30, 2013 and June 30, 2013 reflects the current portion of the Company’s industrial revenue bonds.
	Revolving Credit Facility
	On November 15, 2012, the Company replaced its previous revolving line-of-credit facility with a new $65 million credit facility with BMO Harris Bank N.A., consisting of a $35 million revolving line-of-credit facility (the “Revolving Credit”) to support the Company’s working capital needs and other general corporate purposes, and a $30 million acquisition loan commitment (the “Acquisition Facility” and together with the Revolving Credit, the “Credit Facility”) to finance permitted acquisitions.
	The Credit Facility expires on November 15, 2017, is secured by substantially all assets of the Company and provides for up to an additional $35 million in uncommitted loans available for additional Revolving Credit loans or Acquisition loans.
	Advances under the Acquisition Facility are available until November 15, 2014. Loans under the Acquisition Facility amortize in two tranches, such that loans outstanding on November 15, 2013 begin amortizing in quarterly installments equal to 2.5% of the principal amount outstanding on such date, and advances made after November 15, 2013 and outstanding on November 15, 2014 begin amortizing on the same basis.
	Outstanding borrowings under the Credit Facility bear interest, at the Company’s option, at either LIBOR, fixed for interest periods of one, two, three or six month periods, plus 1.25% to 2.00%, or at the bank’s base rate, as defined, plus 0.25% to 1.00%, based upon the Company’s Total Funded Debt/EBITDA Ratio, as defined. The Company is also required to pay commitment fees on unused portions of the Credit Facility ranging from 0.25% to 0.375%, based on the Company’s Total Funded Debt/EBITDA Ratio, as defined. The effective interest rate on outstanding borrowings under the Credit Facility was 1.45% at September 30, 2013.
	As a condition of the Credit Facility, the Company is subject to certain customary covenants, which it was in compliance with at September 30, 2013. The Company had $28.5 million of borrowings drawn against the Credit Facility at September 30, 2013 and additionally had certain letters of credit outstanding totaling $0.5 million.

	Fair Value Measurements
	The Company’s long-term debt instruments, consisting of industrial revenue bonds, are carried at historical cost. As of September 30, 2013 and June 30, 2013, the fair value of the industrial revenue bonds was approximately $1.9 million and $2.0 million, respectively, compared to carrying values of approximately $1.5 million and $1.5 million, respectively. These fair values, which were derived from discounted cash flow analyses based on the terms of the contracts and observable market data, and adjustment for nonperformance risk, are classified as Level 3 in the fair value hierarchy. The fair value of the Company's Credit Facility debt at September 30, 2013 and June 30, 2013 approximated its carrying value of $28.5 million and $10.0 million, respectively, as the rates on these borrowings are variable in nature. In relation to the acquisition of Creonix and Aydin, the Company estimated the fair value of the assets acquired and liabilities assumed at acquisition date. See Note 3 for a further discussion of these estimated fair values. The fair value of accounts receivable and accounts payable approximated their carrying values at both September 30, 2013 and June 30, 2013.

	Commitments and Contingencies
	Environmental Remediation — Sparton has been involved with ongoing environmental remediation since the early 1980’s related to one of its former manufacturing facilities, located in Albuquerque, New Mexico (“Coors Road”). Although the Company entered into a long-term lease of the Coors Road property that was accounted for as a sale of property during fiscal 2010, it remains responsible for the remediation obligations related to its past operation of this facility. At September 30, 2013, Sparton had accrued approximately $3.1 million as its estimate of the remaining minimum future undiscounted financial liability with respect to this matter, of which approximately $0.5 million is classified as a current liability and included on the balance sheet in other accrued expenses. The Company’s minimum cost estimate is based upon existing technology and excludes certain legal costs, which are expensed as incurred. The Company’s estimate includes equipment and operating and maintenance costs for onsite and offsite pump and treat containment systems, as well as continued onsite and offsite monitoring. It also includes periodic reporting requirements.
	In fiscal 2003, Sparton reached an agreement with the United States Department of Energy (“DOE”) and others to recover certain remediation costs. Under the settlement terms, Sparton received cash and obtained some degree of risk protection as the DOE agreed to reimburse Sparton for 37.5% of certain future environmental expenses in excess of $8.4 million incurred from the date of settlement, if any, of which approximately $4.7 million has been expended as of September 30, 2013 toward the $8.4 million threshold. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable over a continuum of events and activities that help to frame and define a liability. Factors which cause uncertainties for the Company include, but are not limited to, the effectiveness of the current work plans in achieving targeted results and proposals of regulatory agencies for desired methods and outcomes. It is possible that cash flows and results of operations could be materially affected by the impact of changes associated with the ultimate resolution of this contingency. At September 30, 2013, the Company estimates that it is reasonably possible, but not probable, that future environmental remediation costs associated with the Company’s past operations at the Coors Road property, in excess of amounts already recorded and net of DOE reimbursement, could be up to $2.4 million before income taxes over the next seventeen years.
	The Company and its subsidiaries are also involved in certain existing compliance issues with the EPA and various state agencies, including being named as a potentially responsible party at several sites. Potentially responsible parties (“PRP“s) can be held jointly and severally liable for the clean-up costs at any specific site. The Company’s past experience, however, has indicated that when it has contributed relatively small amounts of materials or waste to a specific site relative to other PRPs, its ultimate share of any clean-up costs has been minor. Based upon available information, the Company believes it has contributed only small amounts to those sites in which it is currently viewed as a PRP and that reasonably possible losses related to these compliance issues are immaterial.
	Litigation — On September 24, 2013, L-3 Communications Corporation, doing business as L-3 Linkabit (“Linkabit”) filed a complaint in the United States District Court for the Middle District of Florida, Orlando Division, alleging, among other things, that the Company failed to follow Linkabit drawings for the manufacture and assembly of certain products and that the Company changed its manufacturing process resulting in shipment of defective products to Linkabit. Linkabit seeks damages for breach of contract, breach of covenants, breach of warranties and negligence. The Company believes that its defenses to the claims are very strong and it intends to defend this action vigorously.  Given the stage of the litigation and the unresolved questions of fact, the Company cannot estimate any loss, or range of loss, with confidence at this time.
	U.S. Government Audits — Federal government agencies, including the Defense Contract Audit Agency (“DCAA”) and the Defense Contract Management Agency (“DCMA”), routinely audit and evaluate government contracts and government contractors’ administrative processes and systems. These agencies review the Company’s performance on contracts, pricing practices, cost structure, financial capability and compliance with applicable laws, regulations and standards. They also review the adequacy of the Company’s internal control systems and policies, including the Company’s purchasing, accounting, estimating, compensation and management information processes and systems.
	The Company implemented a new enterprise resource planning system in November 2012 and currently remains eligible to receive cost reimbursable contracts from the U.S. Government. The Company responded in June 2013 to DCAA review comments received in the fourth quarter of fiscal 2013 regarding corrective actions to improve the reliability for accumulating costs under government contracts. While the Company’s corrective actions remain open for further review, the Company remains confident formal resolution of DCAA cost accounting practices findings will not have a material adverse impact on the Company’s financial results.
	Other — In addition to the foregoing, from time to time, the Company is involved in various legal proceedings relating to claims arising in the ordinary course of business. The Company is not currently a party to any other such legal proceedings, the adverse outcome of which, individually or in the aggregate, is expected to have a material adverse effect on our business, financial condition or results of operations.

	Basic earnings per share is based on the weighted average number of common shares and participating securities outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under our stock-based compensation plan and are determined using the treasury stock method. Unvested restricted stock awards, which contain non-forfeitable rights to dividends whether paid or unpaid, are included in the number of shares outstanding for both basic and diluted earnings per share calculations. In the event of a net loss, unvested restricted stock awards are excluded from the calculation of both basic and diluted loss per share.
	Earnings per share calculations, including weighted average number of shares of common stock outstanding used in calculating basic and diluted income per share, for the three months ended September 30, 2013 and 2012 are as follows:

Business Segments	'
	Business Segments
	The Company is a provider of complex and sophisticated electromechanical devices with capabilities that include concept development, design and manufacturing engineering, production, distribution, and field service. Reportable segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and allocating resources. The Company serves the Medical & Biotechnology, Military & Aerospace and Industrial & Commercial markets through three reportable business segments; Medical Device (“Medical”), Complex Systems (“CS”) and Defense & Security Systems (“DSS”).
	The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company's resources on a segment basis. Net sales are attributed to the segment in which the product is manufactured or service is performed. A segment's performance is evaluated based upon its operating income (loss). A segment's operating income (loss) includes its gross profit on sales less its selling and administrative expenses, including allocations of certain corporate operating expenses. Certain corporate operating expenses are allocated to segment results based on the nature of the service provided. Other corporate operating expenses, including certain administrative, financial and human resource activities as well as items such as interest expense, interest income, other income (expense) and income tax expense (benefit), are not allocated to operations and are excluded from segment profit. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Inter-segment transactions are generally accounted for at amounts that approximate arm's length transactions. Identifiable assets by segments are those assets that are used in each segment's operations. The accounting policies for each of the segments are the same as for the Company taken as a whole.
	Medical segment operations are comprised of contract design, manufacturing, and aftermarket repair and refurbishment of sophisticated medical and biotechnology devices and sub-assemblies. Customers include industry leaders, emerging technologies companies and start-ups. In manufacturing devices for its customers, this business unit follows specific design and manufacturing processes to assure product reliability and safety in accordance with Food and Drug Administration (“FDA”) guidelines and approvals.

Accounting Changes and Error Corrections [Abstract]	'
New Accounting Standards	'
	Change in Accounting Principle
	In the first quarter of fiscal 2014, the Company voluntarily changed its revenue recognition policy related to DSS sonobuoy sales to the U.S. Navy and foreign government customers under long-term contracts that require lot acceptance testing. The new policy continues to recognize revenue under the percentage of completion method, but changes the measurement of progress under these contracts from a completed units accepted basis (whereby revenue was recognized for each lot of sonobuoys produced when that lot was formally accepted by the customer) to a units-of-production basis (whereby revenue is recognized when production and internal testing of each lot of sonobuoys is completed). The Company now has significant experience in producing sonobuoys to customer specifications and internal testing to assess compliance with those specifications and, as such, now has an adequate history of continuous customer acceptance of all sonobuoys produced. Accordingly, the Company believes the new method is preferable primarily because it eliminates delays in revenue and related cost of goods sold recognition due to timing of customer testing and acceptance delays. Such delays commonly occur due to customer circumstances that are unrelated to the product produced. Under the new policy, the revenue and related costs of goods sold of these manufactured sonobuoy lots will more closely match the period in which the product was produced and the related revenue earned, thereby better reflecting the economic activity of the DSS segment. Additionally, this new method provides better matching of periodic operating expenses incurred during production.
	For the three months ended September 30, 2013, this change in accounting policy increased DSS and consolidated net sales and gross profit by $2.2 million and $1.0 million, respectively, and basic and diluted income per share each by $0.07. The following tables present the effects of the retrospective application of this voluntary change in accounting principle (Dollars in thousands, except share amounts):

	New Accounting Standards
	In July 2013, the Financial Accounting Standards Board (the "FASB") issued authoritative guidance under Accounting Standards Update No. 2013-11 ("ASU 2013-11"), which provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss (“NOL”) carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a NOL or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This accounting standard update requires entities to assess whether to net the unrecognized tax benefit with a deferred tax asset as of the reporting date. ASU 2013-11 will be effective for the Company’s first quarter of fiscal 2015. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
