PART I

Item 1. Business

The Company has been in continuous existence since 1900. It was last reorganized in 1919 as an Ohio corporation. The Company’s operations are in one line of business, electronic manufacturing services (EMS). The Company provides design and electronic manufacturing services, which include a complete range of engineering, pre-manufacturing and post-manufacturing services. Capabilities range from product design and development through aftermarket support. All of the facilities are registered to ISO standards, including 9001 or 13485, with most having additional certifications. Products and services include complete “Box Build” products for Original Equipment Manufacturers, microprocessor-based systems, transducers, printed circuit boards and assemblies, sensors and electromechanical devices for the medical/scientific instrumentation, electronics, aerospace, and other industries, as well as engineering services relating to these product sales. The Company also designs and manufactures sonobuoys, anti-submarine warfare (ASW) devices, used by the U.S. Navy and other free-world countries. See Note 12 to the Consolidated Financial Statements included in Item 8 of this report for information regarding the Company’s product sales concentration and locations of long-lived assets. The Company’s website address is www.sparton.com. Information provided at the website includes, among other items, the Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Quarterly Earnings Releases, News Releases, Governance Guidelines, and the Code of Ethics, as well as various Board of Director committee charters. The Company provides, free of charge, copies of its periodic and current reports (e.g., Forms 10-K, 10-Q and 8-K) and amendments to such reports that are filed with the Securities and Exchange Commission (SEC), as well as the Board of Director committee charters. Reports are available as soon as reasonably practicable after such reports are filed with or furnished to the SEC, either at the Company’s website, through a link to the SEC’s site or through the Company’s Shareowner Relations Department.

Electronic Contract Manufacturing Services

Historically, the Company’s principal electronics product was sonobuoys, which are ASW devices used by the U.S. Navy and other free-world military organizations. The Company competes with a very limited number of qualified manufacturers for sonobuoy procurements by the U.S. and select foreign governments. Contracts are obtained through competitive bid or direct procurement. Certain sonobuoy contracts are awarded and produced through a joint venture agreement with UnderSea Sensor Systems, Inc. (USSI), another producer of sonobuoys. USSI’s parent company is Ultra Electronics Holdings PLC, based in the United Kingdom. The joint venture arrangement operates under the name ERAPSCO. ERAPSCO allows the two companies to consolidate their own unique and complementary backgrounds and to jointly develop and produce certain agreed-upon designs for the U.S. Navy. While the joint agreement provides the opportunity to maximize efficiencies in the design and development of the related sonobuoys, both companies function independently; therefore, there is no separate entity to be accounted for or consolidated. Thus, individual contract risk exposures are reduced, while simultaneously enhancing the likelihood of achieving U.S. Navy and other ASW objectives. In general, the agreed upon designs included under the joint venture agreement are developmental or are sonobuoys with low volume demand, although the Company would like to expand the ERAPSCO arrangement to potentially include all sonobuoy efforts.

The Company is now focused on substantially expanding sales in the high-mix, low to medium-volume non-sonobuoy EMS markets. High-mix describes customers needing multiple product types with generally low volume manufacturing runs. This is where the Company expects substantial future revenue growth, with emphasis on government, aerospace, medical/scientific instrumentation, and industrial markets. Many of the physical and technical attributes in the production of electronics for sonobuoys are the same as those required in the production of other electrical and electromechanical products and assemblies. The Company’s EMS business includes design and/or manufacture of a variety of electronic and electromechanical products and assemblies. Sales are generally obtained on a competitive basis. Competitive factors include technical ability, customer service, product quality, timely delivery and price.

Non-sonobuoy electronic contract manufacturing and services are sold primarily through a direct sales force. Design services in the non-sonobuoy area are supported by an engineering organization, with centralized management and decentralized operations, which allows the Company to deliver products and services in an efficient manner and enhances the Company’s focus on new and expanding technologies. In the commercial EMS business, Sparton must compete with a significant number of domestic and foreign manufacturers, some of which are much larger in terms of size and/or financial resources. The Company generally contracts with its customers to manufacture products based on the customer’s design, specifications and shipping schedules. Normally, EMS programs do not require the Company’s direct involvement in original equipment manufacturer product marketing. Material cost and availability, product quality, delivery and reliability are all very important factors in the commercial EMS business.

The Company signed a membership purchase agreement and completed the acquisition of Astro Instrumentation, LLC (“Astro”) on May 31, 2006. Astro was a privately-owned EMS company located in Strongsville, Ohio (near Cleveland) which had been in business for approximately five years. Under the terms of the purchase agreement, the previous owners

		Sparton Corporation 2006 Annual Report			5

entered into non-competition agreements with the Company. Astro is an EMS provider that designs and manufactures a variety of specialized medical products, generally involving high-quality medical laboratory test equipment. The acquisition of Astro furthered the Company’s strategy of identifying, evaluating and purchasing potential acquisition candidates in both the defense and medical device markets. The Company believes the acquisition of Astro will favorably position Sparton within the medical market to attract and expand its customer base. Astro operates from a 40,000 square foot facility in an industrial park. A 20,000 square foot addition to the facility is now under construction. Sparton operates the business as a wholly-owned subsidiary at its present location and with the current manufacturing management and staff. The Company’s intentions are to integrate Astro’s operations and general management oversite with those of the other Sparton locations.

In May 2005, Spartronics, the Company’s Vietnam based subsidiary, began regular production. This facility, located just outside of Ho Chi Minh City, is anticipated to provide growth opportunities for the Company, in current as well as new markets. Spartronics is a full service manufacturing facility, providing an off shore option for customers requesting this type of production facility.

At June 30, 2006 and 2005, the government funded backlog was approximately $41 million and $42 million, respectively. A majority of the fiscal 2006 backlog is expected to be realized in the next 12-15 months. Commercial EMS sales are not included in the backlog. The Company does not believe the amount of backlog of commercial sales covered by firm purchase orders is a meaningful measure of future sales, as such orders may be rescheduled or cancelled without significant penalty.

Other

One of Sparton’s largest customers is the U.S. Navy. While the loss of U.S. government sonobuoy sales would have a material adverse financial effect on the Company, the loss of any one of several other customers, including Honeywell and Bally both with sales in excess of 10% of total sales, could also have a significant financial impact. The Company continues to grow its non-sonobuoy EMS sales with the objective of expanding the customer base, thus reducing the Company’s exposure to any single customer. The Astro acquisition will further expand our customer base. While overall sales fluctuate during the year, such fluctuations do not reflect a seasonal pattern or tendency.

Materials for the electronics operations are generally available from a variety of worldwide sources, except for selected components. Access to competitively priced materials is critical to success in the EMS business. In certain markets, the volume purchasing power of the larger competitors creates a cost advantage for them. Although the electronics industry has experienced spot shortages, the Company does not expect to encounter significant long-term problems in obtaining sufficient raw materials. The risk of material obsolescence in the contract EMS business is less than it is in many other markets because raw materials and component parts are generally purchased only upon receipt of a customer’s order. However, excess material resulting from order lead-time is a risk factor due to potential order cancellation or design changes by customers.

Expenditures for research and development (R&D) not funded by customers amounted to approximately $882,000 in fiscal 2006, compared to $1,756,000 in fiscal 2004, and these expenses were included in selling and administrative expense. There were no non-funded R&D expenditures in fiscal 2005. Customer funded R&D costs are generally not considered material, are usually part of a larger production agreement, and as such are included in both sales and costs of goods sold. While there are approximately 73 employees involved in R&D activities, none are engaged in this activity on a full time basis.

Sparton employed approximately 1,200 people at June 30, 2006. The Company has one manufacturing division and five wholly-owned active manufacturing subsidiaries, including the recent addition of Astro.

Item l(a). Risk Factors

We operate in a changing economic, political and technological environment that presents numerous risks, many of which are driven by factors that we cannot control or predict. The following discussion, as well as our “Critical Accounting Policies and Estimates” and “Management’s Discussion and Analysis” in Item 7, highlight some of these risks. The terms “Sparton,” “the Company,” “we,” “us,” and “our” refer to Sparton Corporation and Subsidiaries.

The industry is extremely competitive and we depend on continued outsourcing by OEMs.

The EMS industry in general is highly fragmented and intensely competitive. The contract manufacturing services provided are available from many sources, and we compete with numerous domestic and foreign EMS firms. Within Sparton’s target market, the high-mix, low to medium-volume sector of the EMS industry, there are substantially fewer competitors, but competition remains strong. Some competitors have substantially greater manufacturing, R&D, marketing, and/or financial resources and in some cases have more geographically diversified international operations, including manufacturing facilities in Europe and South America. Sparton expects competition to intensify further as more companies enter our target

		Sparton Corporation 2006 Annual Report			6

markets and our customers consolidate. In the future, increased competition from large electronic component manufacturers that are selling, or may begin to sell, electronics manufacturing services may occur. Future growth will depend on new outsourcing opportunities, and could be limited by OEMs performing such functions internally or delaying their decision to outsource.

In some cases, Sparton may not be able to offer prices as low as some competitors because those competitors may have lower cost structures for the services they provide, or because such competitors are willing to accept business at lower margins in order to utilize more of their excess capacity. In that event, net sales would decline. At times Sparton may be operating at a cost disadvantage compared to some competitors who have greater direct buying power. As a result, competitors may have a competitive advantage and obtain business from our customers.

Principal competitive factors in our targeted market are believed to be quality, reliability, the ability to meet delivery schedules, technological sophistication, geographic location, and price. During periods of recession in the electronics industry, our competitive advantages in the areas of adaptive manufacturing and responsive customer service may be of reduced importance due to increased price sensitivity. We also expect our competitors to continue to improve the performance of their current products or services, to reduce their current products or service sales prices and to introduce new products or services that may offer greater performance and improved pricing. Any of these could cause a decline in sales, loss of market acceptance of our products or services, profit margin compression, or loss of market share.

Our operating results are subject to general economic conditions and may vary significantly from period to period due to a number of factors.

We are subject to inflation, interest rate changes, availability of capital markets, consumer spending rates, the effects of governmental plans to manage economic conditions and other national and global economic occurrences beyond our control. Such factors, economic weakness, and constrained customer spending have resulted in the past, and may result in the future, in decreased revenue, gross margin, earnings, or growth rates.

We often experience significant fluctuations in our annual and quarterly results of operations. In addition to general economic conditions, other factors that contribute to these fluctuations are Sparton’s effectiveness in managing the manufacturing processes and costs in order to decrease manufacturing expenses, as well as the level of capacity utilization of our manufacturing facilities and associated fixed costs. Sparton’s ASW sales are totally dependent upon access to the U.S. Navy’s test facilities for sonobuoys. Additionally, the Company relies on our customer’s demands, which can and does change dramatically. Such factors also could affect our results of operations in the future.

Start-up costs and inefficiencies related to new or transferred programs can adversely affect our operating results and may not be recoverable.

Start-up costs, the management of labor and equipment resources in connection with new programs and new customer relationships, and the need to estimate required resources in advance can adversely affect profit margins and operating results. These factors are particularly evident with the introduction of new products and programs. The effects of these start-up costs and inefficiencies can also occur when new facilities are opened, such as our facility near Ho Chi Minh City, Vietnam that opened in fiscal 2005.

If new programs or new customer relationships are terminated or delayed, our operating results may be harmed, particularly in the near term. We may not be able to recoup our start-up costs or replace anticipated new program revenues.

We depend on limited or sole source suppliers for some critical components; the inability to obtain components as required, with favorable purchase terms, could harm our business.

A significant portion of our costs are related to electronic components purchased to produce our products. In some cases, there may be only one supplier of a particular component. Supply shortages for a particular component can delay production, and thus delay shipments to customers and the associated revenue of all products using that component. This could cause the Company to experience a reduction in sales, increased inventory levels and costs, and could adversely affect relationships with existing and prospective customers. In the past, we have secured sufficient allocations of constrained components so that revenue was not materially impacted. If we are unable to procure necessary components under favorable purchase terms, including at favorable prices and with the order lead-times needed for the efficient and profitable operation of our factories, our results of operations could suffer.

		Sparton Corporation 2006 Annual Report			7

We are dependent on a few large customers; the loss of such customers or reduction in their demand could substantially harm our business and operating results.

For the fiscal year ended June 30, 2006, our six largest customers, including the US government, accounted for approximately 77% of net sales. U.S. governmental sales, primarily the US Navy, represented 22% of our fiscal 2006 sales. We expect to continue to depend upon a relatively small number of customers, but cannot ensure that present or future large customers will not terminate, significantly change, reduce, or delay their manufacturing arrangements with us. Because our major customers represent such a large part of our business, the loss of any of our major customers or reduced sales to these customers could negatively impact our business. While the integration of Astro is anticipated to expand our customer base, currently Astro’s customer base is also highly concentrated, with approximately 80% of their sales to one customer with several locations.

We rely on the continued growth and financial stability of our customers, including our major customers. Adverse changes in the end markets they serve can reduce demand from our customers in those markets and/or make customers in these end markets more price sensitive. Furthermore, mergers or restructurings among our customers or our customers’ customers could increase concentration and/or reduce total demand as the combined entities rationalize their business and consolidate their suppliers. Future developments, particularly in those in end markets which account for more significant portions of our revenues, could harm our business and our results of operations.

Future governmental sales could be affected by a decrease in defense spending by the U.S. government, or by changes in spending allocation that could result in one or more of the Company’s programs being reduced, delayed or terminated, which would adversely affect our financial results. The Company’s U.S. governmental sales are funded by the federal budget. Changes in congressional schedules, negotiations for program funding levels or unforeseen world events can interrupt the funding for a program or contract. The timing of sonobuoy sales to the U.S. Navy is dependent upon access to, and successful passage of, product tests by the U.S. Navy. Reduced governmental budgets have made access to the test range less predictable and less frequent than in the past, which has impacted our reported revenues.

Sparton generates large accounts receivable in connection with our providing of electronic contract manufacturing. If one or more of our customers experiences financial difficulty and is unable to pay for the services provided, our operating results and financial condition would be adversely affected.

Customer cancellations, reductions, or delays could adversely affect our operating results.

We generally do not obtain long-term purchase commitments from our customers. Customers may cancel orders, delay the delivery of orders, or release orders for fewer products than we previously anticipated for a variety of reasons, including decreases in demand for their products and services. Such changes by a significant customer, by a group of customers, or by a single customer whose production is material to an individual facility could seriously harm results of that operation in that period. In addition, since much of our costs and operating expenses are relatively fixed, a reduction in customer demand would adversely affect our margins and operating income. Although we are always seeking new opportunities, we cannot be assured that we will be able to replace deferred, reduced or cancelled orders.

Our inability to forecast the level of customer orders with much certainty makes it difficult to schedule production and maximize utilization of manufacturing capacity. If actual demand is higher than anticipated, we may be required to increase staffing and other expenses in order to meet such demand of our customers. Alternatively, anticipated orders from our customers may fail to materialize, thereby adversely affecting our results of operations. Such customer order fluctuations and deferrals have had a material adverse effect on us in the past, and we may experience such effects in the future.

Such order changes could cause a delay in the repayment to us for inventory expenditures we incurred in preparation for the customer’s orders or, in certain circumstances, require us to return the inventory to our suppliers, re-sell the inventory to another customer or continue to hold the inventory. In some cases excess material resulting from longer order lead-time is a risk due to the potential of order cancellation or design changes by customers. Additionally, dramatic changes in circumstances for a customer could also negatively impact the carrying value of our inventory for that customer.

The Company and its customers may be unable to keep current with technological changes.

The Company’s customers’ participate in markets that have rapidly changing technology, evolving industry standards, frequent new product introductions, and relatively short product life cycles. The introduction of products embodying new technologies or the emergence of new industry standards can render existing products obsolete or unmarketable. The Company’s success depends upon our customers’ ability to enhance existing products and to develop and introduce new products, on a timely and cost-effective basis, that keep pace with technological developments and emerging industry standards, and

		Sparton Corporation 2006 Annual Report			8

address increasingly sophisticated customer requirements. There is no assurance that the Company’s customers will do so and failure to do so could substantially harm the Company’s customers and indirectly the Company.

Additionally, the Company’s future success will depend upon its ability to maintain and enhance its own technological capabilities, develop and market manufacturing services which meet changing customer needs, and successfully anticipate or respond to technological changes in manufacturing processes on a cost-effective and timely basis. If Sparton is unable to do so, business, financial condition and operating results could be materially adversely affected.

Fluctuations in foreign currency exchange rates could increase operating costs.

A portion of the Company’s operations and some customers are in foreign locations. As a result, transactions may occur in currencies other than the U.S. dollar. Currency exchange rates fluctuate on a daily basis as a result of a number of factors and cannot be easily predicted. Volatility in the functional currencies of our entities and the U.S. dollar could seriously harm our business, operating results and financial condition. The primary impact of currency exchange fluctuations is on the adjustments related to the translation of the Company’s Canadian and Vietnamese financial statements into U.S. dollars, which are included in current earnings, as well as impacting the cash, receivables, and payables of our operating entities. The Company currently does not use financial instruments to hedge foreign currency fluctuation and unexpected expenses could occur from future fluctuations in exchange rates.

Failure to attract and retain key personnel and skilled associates could hurt operations.

Our success depends to a large extent upon the continued services of key management personnel. We cannot be assured that we will retain our key employees, and the loss of service of any of these officers or key management personnel could have a material adverse effect on our business growth and operating results.

Our future success will require an ability to attract and retain qualified employees. Competition for such personnel is intense, and we cannot be assured that we will be successful in attracting and retaining such personnel. Changes in the cost of providing pension and other employee benefits, including changes in health care costs, investment returns on plan assets, and discount rates used to calculate pension and related liabilities, could lead to increased costs in any of our operations.

We are involved in legal proceedings and unfavorable decisions could materially affect us.

Our business activities expose us to risks of litigation with respect to our customers, suppliers, creditors, shareowners, product liability, or environmental-related matters. We may incur significant expense to defend or otherwise address current or future claims. Any litigation, even a claim without merit, could result in substantial costs and diversion of resources, and could have a material adverse effect on our business and results of operations.

Also, in the past, we have filed claims relating to various matters, including product defects discovered in certain aerospace circuit boards, which were supplied to us. Although we are pursuing such claims, we cannot predict the outcome. If we are not able to obtain a sufficient recovery, our business and operating results could be adversely impacted. Refer to Item 3 – “Legal Proceedings” of this report.

Adverse regulatory developments could harm our business.

Our business operates in heavily regulated environments. We must manage the risk of changes in or adverse actions under applicable law or in our regulatory authorizations, licenses and permits, governmental security clearances or other legal rights in order to operate our business, manage our work force, or import and export goods and services as needed. We also face the risk of other adverse regulatory actions, compliance costs, or governmental sanctions.

Business disruptions could seriously harm our business and results of operations.

Increased international political instability, evidenced by threats and occurrence of terrorist attacks, conflicts in the Middle East and Asia, and strained international relations arising from these conflicts, may hinder our ability to do business. The political environment in communist countries can contribute to the threat of instability. While we have not been adversely affected as yet due to this exposure, one of our facilities is based in Vietnam, which is a communist country. These events may continue to have an adverse impact on the U.S. and world economies, particularly customer confidence and spending, which in turn could affect our revenue and results of operations. The impact of these events on the volatility of the U.S. and world financial markets could increase the volatility of our securities and may limit the capital resources available to us, our customers and our suppliers.

		Sparton Corporation 2006 Annual Report			9

Our worldwide operations could be subject to natural disasters and other business disruptions, including earthquakes, power shortages, telecommunications failures, water shortages, tsunamis, floods, hurricanes, fires, and other natural or manmade disasters, which could seriously harm our financial condition and increase our expenses. In the past, hurricanes have adversely impacted the performance of two of our production facilities located in Florida.

We have a production facility outside Ho Chi Minh City, Vietnam, which is in the area affected by avian flu. To the best of our knowledge, concerns about the spread of avian flu have not affected our employees or operations. However, our Asian production could be severely impacted by an epidemic spread of avian flu. Concerns relating to avian flu are currently focused on Asia; however, avian flu or other epidemics could similarly affect facilities in other locations. These factors could also affect our suppliers and customers, and results of operations.

Recently enacted changes in the securities laws and regulations have increased, and are likely to continue to increase, our costs.

The Sarbanes-Oxley Act of 2002 that became law in July 2002 has required changes in some of our corporate governance, securities disclosure and compliance practices. In response to the requirements of that Act, the Securities and Exchange Commission and the New York Stock Exchange have promulgated new rules on a variety of subjects. Compliance with these new rules, particularly preparation for future compliance with Section 404 of the Sarbanes-Oxley Act regarding management’s assessment of internal control over financial reporting, which will become applicable to Sparton at a future date, has increased our legal, financial, and accounting costs. We expect some level of increased costs related to these new regulations to continue indefinitely. While preparation and consulting costs are anticipated to decline, audit costs related to the regulation are expected to increase. The extent of the ongoing and future costs is unknown at this time due to the SEC’s, and other regulatory entities’, pending guidance related to smaller companies. However, absent significant changes in related rules (which we cannot assure), we anticipate these costs may decline somewhat in future years as we become more efficient in our compliance processes. We also expect these developments to make it more difficult and more expensive to obtain director and officer liability insurance, and we may be forced to accept reduced coverage or incur substantially higher costs to obtain coverage. Likewise, these developments may make it more difficult for us to attract and retain qualified members of our board of directors or qualified management personnel.

We are subject to a variety of environmental laws, which expose us to potential liability.

Our operations are regulated under a number of federal, state, provincial, local and foreign environmental laws and regulations, which govern, among other things, the discharge of hazardous materials into the air and water, as well as the handling, storage and disposal of such materials. These laws and regulations include the Clean Air Act, the Clean Water Act, the Resource, Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation and Liability Act, as well as analogous state and foreign laws. Compliance with these environmental laws is a significant consideration for us because we use various hazardous materials in our manufacturing processes. We may be liable under environmental laws for the cost of cleaning up properties we own or operate if they are or become contaminated by the release of hazardous materials, regardless of whether we caused the release, even if we fully comply with applicable environmental laws. In the event of contamination or violation of environmental laws, we could be held liable for damages including fines, penalties and the costs of remedial actions and could also be subject to revocation of our discharge permits. Any such penalties or revocations could require us to cease or limit production at one or more of our facilities, thereby harming our business. In addition, such regulations could restrict our ability to expand our facilities or could require us to acquire costly equipment, or to incur other significant expenses to comply with environmental regulations, including expenses associated with the recall of any non-compliant product. See Item 3 – “Legal Proceedings” of this report.

Certain shareowners have significant control and shares eligible for public sale could adversely affect the share price.

As of June 30, 2006, the directors, executive officers and 5% shareowners beneficially owned an aggregate of approximately 49% of our common stock, of which Bradley O. Smith, the Chairman of the Board, beneficially owned or controlled approximately 24%. Accordingly, certain persons have significant influence over the election of our Board of Directors, the approval or disapproval of any other matters requiring shareowner approval, and the affairs and policies of Sparton. Such voting power could also have the effect of deterring or preventing a change in control of the Company that might otherwise be beneficial to other shareowners. In addition, substantially all of the outstanding shares of common stock are freely tradable without restriction or further registration. Sales of substantial amounts of common stock by shareowners, or even the potential for such sales, may cause the market price to decline and could impair the ability to raise capital through the sale of equity securities.

		Sparton Corporation 2006 Annual Report			10

In the future, we may need additional funding, which may be raised through issuances of equity securities. We also have the right to issue shares upon such terms and conditions and at such prices as our Board of Directors may establish. Such offerings would dilute the ownership interest of existing shareholders and could cause a dilution of the net tangible book value of such shares.

At June 30, 2006, there were options outstanding for the purchase of approximately 517,000 shares of common stock of the Company, of which options for approximately 369,000 shares were vested and exercisable. Holders of the common stock could suffer dilution if outstanding common stock options are exercised.

Our stock price may be volatile, and the stock is thinly traded, which may cause investors to lose most or part of their investment in our common stock.

The stock market may experience volatility that is often unrelated to the operating performance of any particular company or companies. If market-sector or industry-based fluctuations occur, our stock price could decline regardless of our actual operating performance, and investors could lose a substantial part of their investments.

Moreover, if an active public market for our common stock is not sustained in the future, it may be difficult to resell such stock. For the three months ended August 1, 2006, the average number of shares of our common stock that traded on the NYSE has been approximately 2,300 shares per day. We had approximately 9,392,000 issued and outstanding shares as of June 30, 2006. When trading volumes are this low, a relatively small buy or sell order can result in a relatively large change in the trading price of our common stock and investors may not be able to sell their securities at a favorable price. In addition, should the vested and exercisable stock options be exercised and simultaneously sold (to fund the cost of the exercise and the related taxes), our stock price would be significantly adversely impacted.

Item l(b). Unresolved Staff Comments

None.

Item 2. Properties

The following is a listing of the principal properties used by Sparton in its business. Except as described below, Sparton owns all of these properties. These facilities provide a total of approximately 897,000 square feet of manufacturing and administrative space, which includes the additional 20,000 square feet of new facilities under construction in Strongsville, Ohio. There are manufacturing and/or office facilities at each location. Reflective of the current economic environment, Sparton’s manufacturing facilities are underutilized. Underutilized percentages vary by plant; however, ample space exists to accommodate expected growth. Sparton believes these facilities are suitable for its operations.

Jackson, Michigan DeLeon Springs, Florida Brooksville, Florida Albuquerque, New Mexico		Deming, New Mexico Strongsville, Ohio London, Ontario, Canada Thuan An District, Binh Duong Province, Vietnam (Outside Ho Chi Minh City)

While the Company owns the building and other assets for Spartronics, including its manufacturing facility in Vietnam, the land is occupied under a long-term lease covering approximately 40 years. This is a prepaid lease, which cost is amortized over the life of the lease, and carried in other long-term assets on our balance sheet.

Not included above with the Company’s owned properties is the Company’s Coors Road, Albuquerque, New Mexico, facility. While this property is owned by Sparton, and included in the property, plant, and equipment section of our balance sheet, it is not used in Sparton’s manufacturing operations. Sparton leases this facility to another company under a long-term lease, which contains an option to buy.

Item 3. Legal Proceedings

Various litigation is pending against the Company, in many cases involving ordinary and routine claims incidental to the business of the Company and in others presenting allegations that are non-routine.

Environmental Remediation

The Company and its subsidiaries are involved in certain compliance issues with the United States Environmental Protection Agency (EPA) and various state agencies, including being named as a potentially responsible party at several sites. Potentially responsible parties (PRPs) can be held jointly and severally liable for the clean-up costs at any specific site.

		Sparton Corporation 2006 Annual Report			11

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.

In February 1997, several lawsuits were filed against Sparton’s wholly-owned subsidiary, Sparton Technology, Inc. (STI), alleging that STI’s Coors Road facility presented an imminent and substantial threat to human health or the environment. On March 3, 2000, a Consent Decree was entered into, settling the lawsuits. The Consent Decree represents a judicially enforceable settlement and contains work plans describing remedial activity STI agreed to undertake. The remediation activities called for by the work plans have been installed and are either completed or are currently in operation. It is anticipated that ongoing remediation activities will operate for a period of time during which STI and the regulatory agencies will analyze their effectiveness. The Company believes that it will take several years before the effectiveness of the groundwater containment wells can be established. Documentation and research for the preparation of the initial multi-year report and review are currently underway. If current remedial operations are deemed ineffective, additional remedies may be imposed at a significantly increased cost. There is no assurance that additional costs greater than the amount accrued will not be incurred or that no adverse changes in environmental laws or their interpretation will occur.

Upon entering into the Consent Decree, the Company reviewed its estimates of the future costs expected to be incurred in connection with its remediation of the environmental issues associated with its Coors Road facility over the next 30 years. At June 30, 2006, the undiscounted minimum accrual for future EPA remediation approximates $6,287,000. The Company’s estimate is based upon existing technology and current costs have not been discounted. The estimate includes equipment, operating and maintenance costs for the onsite and offsite pump and treat containment systems, as well as continued onsite and offsite monitoring. It also includes the required periodic reporting requirements. This estimate does not include legal and related consulting costs, which are expensed as incurred.

In 1998, STI commenced litigation in two courts against the United States Department of Energy (DOE) and others seeking reimbursement of Sparton’s costs incurred in complying with, and defending against, federal and state environmental requirements with respect to its former Coors Road manufacturing facility. Sparton also sought to recover costs being incurred by the Company as part of its continuing remediation at the Coors Road facility. In fiscal 2003, Sparton reached an agreement with the DOE and others to recover certain remediation costs. Under the agreement, Sparton was reimbursed a portion of the costs the Company incurred in its investigation and site remediation efforts at the Coors Road facility. Under the settlement terms, Sparton received cash and the DOE agreed to reimburse Sparton for 37.5% of certain future environmental expenses in excess of $8,400,000 from the date of settlement. With the settlement, Sparton received cash and obtained some degree of risk protection, with the DOE sharing in costs incurred above the established level.

In 1995, Sparton Corporation and STI filed a Complaint in the Circuit Court of Cook County, Illinois, against Lumbermens Mutual Casualty Company and American Manufacturers Mutual Insurance Company demanding reimbursement of expenses incurred in connection with its remediation efforts at the Coors Road facility based on various primary and excess comprehensive general liability policies in effect between 1959 and 1975. In June 2005, Sparton reached an agreement with the insurers under which Sparton received $5,455,000 in cash in July 2005. This agreement reflects a recovery of a portion of past costs the Company incurred in its investigation and site remediation efforts, which began in 1983, and was recorded as income in June of fiscal 2005. The Company continues to pursue additional recoveries from excess carriers. The probability and amounts of recovery are uncertain at this time.

Customer Relationships

In September 2002, STI filed an action in the U.S. District Court for the Eastern District of Michigan to recover certain unreimbursed costs incurred as a result of a manufacturing relationship with two entities, Util-Link, LLC (Util-Link) of Delaware and National Rural Telecommunications Cooperative (NRTC) of the District of Columbia. On or about October 21, 2002, the defendants filed a counterclaim seeking money damages alleging that STI breached its duties in the manufacture of products for the defendants. The defendant NRTC asked for damages in the amount of $20 million for the loss of its investment in and loans to Util-Link. In addition, the defendant Util-Link had asked for damages in the amount of $25 million for lost profits. Sparton had reviewed these claims and believed they were duplicative. Util-Link did not pursue its claim at the below discussed trial.

The jury trial commenced on September 19, 2005 and concluded on November 9, 2005. The jury awarded Sparton damages in the amount of $3.6 million, of which approximately $1.9 million represented costs related to the acquisition of raw materials. These costs were previously deferred and are included in other long-term assets on the Company’s June 30, 2006 balance sheet. As expected, there were post-trial proceedings, including motions by the defendant NRTC for judgment as matter of law on its counterclaim and a motion for new trial. On March 27, 2006, the trial court denied the defendant NRTC’s motion for judgment on its counter claim as a matter of law and granted the motion for new trial unless

		Sparton Corporation 2006 Annual Report			12

Sparton accepted a reduction of the judgment. Sparton accepted the reduction, which reduced the collective judgment in its favor to $1.9 million, which would enable the Company to recover the deferred costs and, accordingly, there would be no significant impact on operating results. An amended judgment was entered for $1.9 million in Sparton’s favor on April 5, 2006. On May 1, 2006, NRTC filed an appeal of the judgment, which could impact the ultimate result.

The Company has pending an action before the Federal Court of Claims to recover damages arising out of an alleged infringement by the U.S. Navy of certain patents held by Sparton and used in the production of sonobuoys. The case was dismissed on summary judgment; however, the decision of the Court of Claims was reversed by the Court of Appeals. The case is currently scheduled for trial in the first calendar quarter of 2007. The likelihood that the claim will be resolved and the extent of any recovery in favor of the Company is unknown at this time.

Product Issues

Some of the printed circuit boards supplied to the Company for its aerospace sales have been discovered to be defective. The defect occurred during production at the board supplier’s facility, prior to shipment to Sparton for further processing. Sparton; the board manufacturer, Electropac Co., Inc.; and our customer, who received the defective boards, have contained the defective boards. While investigations are underway, $2.9 million of related product and associated expenses have been deferred and classified in Sparton’s balance sheet within other long-term assets as of June 30, 2006. In August 2005, Sparton Electronics Florida, Inc. filed an action in U.S. District Court of Florida against Electropac Co., Inc. to recover these costs. The likelihood that the claim will be resolved and the extent of Sparton’s exposure, if any, is unknown at this time. No loss contingency has been established at June 30, 2006.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis of certain significant events affecting the Company’s earnings and financial condition during the periods included in the accompanying financial statements. Additional information regarding the Company can be accessed via Sparton’s website at www.sparton.com. Information provided at the website includes, among other items, the Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Quarterly Earnings Releases, News Releases, and the Code of Ethics, as well as various corporate charters. The Company’s operations are in one line of business, electronic manufacturing services (EMS). Sparton’s capabilities range from product design and development through aftermarket support, specializing in total business solutions for government, medical/scientific instrumentation, aerospace and industrial markets. This includes the design, development and/or manufacture of electronic parts and assemblies for both government and commercial customers worldwide. Governmental sales are mainly sonobuoys.

The Private Securities Litigation Reform Act of 1995 reflects Congress’ determination that the disclosure of forward-looking information is desirable for investors and encourages such disclosure by providing a safe harbor for forward-looking statements by corporate management. This report on Form 10-K contains forward-looking statements within the scope of the Securities Act of 1933 and the Securities Exchange Act of 1934. The words “expects,” “anticipates,” “believes,” “intends,” “plans,” “will,” “shall,” and similar expressions, and the negatives of such expressions, are intended to identify forward-looking statements. In addition, any statements which refer to expectations, projections or other characterizations of future events or circumstances are forward-looking statements. The Company undertakes no obligation to publicly disclose any revisions to these forward-looking statements to reflect events or circumstances occurring subsequent to filing this Form 10-K with the Securities and Exchange Commission (SEC). These forward-looking statements are subject to risks and uncertainties, including, without limitation, those discussed below. Accordingly, Sparton’s future results may differ materially from historical results or from those discussed or implied by these forward-looking statements. The Company notes that a variety of factors could cause the actual results and experience to differ materially from anticipated results or other expectations expressed in the Company’s forward-looking statements.

Sparton, as a high-mix, low to medium-volume supplier, provides rapid product turnaround for customers. High-mix describes customers needing multiple product types with generally low volume manufacturing runs. As a contract manufacturer with customers in a variety of markets, the Company has substantially less visibility of end user demand and, therefore, forecasting sales can be problematic. Customers may cancel their orders, change production quantities and/or reschedule production for a number of reasons. Depressed economic conditions may result in customers delaying delivery of product, or the placement of purchase orders for lower volumes than previously anticipated. Unplanned cancellations, reductions, or delays by customers may negatively impact the Company’s results of operations. As many of the Company’s costs and operating expenses are relatively fixed within given ranges of production, a reduction in customer demand can disproportionately affect the Company’s gross margins and operating income. The majority of the Company’s sales have historically come from a limited number of customers. Significant reductions in sales to, or a loss of, one of these customers could materially impact business if the Company were not able to replace those sales with new business.

Other risks and uncertainties that may affect operations, performance, growth forecasts and business results include, but are not limited to, timing and fluctuations in U.S. and/or world economies, competition in the overall EMS business, availability of production labor and management services under terms acceptable to the Company, Congressional budget outlays for sonobuoy development and production, Congressional legislation, foreign currency exchange rate risk, uncertainties associated with the costs and benefits of new facilities, including the plant in Vietnam and the Company’s newest subsidiary Astro Instrumentation, Inc., and the closing of others, uncertainties associated with the outcome of litigation, changes in the interpretation of environmental laws and the uncertainties of environmental remediation, and uncertainties related to defects discovered in certain of the Company’s aerospace circuit boards. Further risk factors are the availability and cost of materials. A number of events can impact these risks and uncertainties, including potential escalating utility and other related costs due to natural disasters, as well as political uncertainties such as the conflict in Iraq. The Company has encountered availability and extended lead time issues on some electronic components in the past when market demand has been strong; this resulted in higher prices and late deliveries. Additionally, the timing of sonobuoy sales to the U.S. Navy is dependent upon access to the test range and successful passage of product tests performed by the U.S. Navy. Reduced governmental budgets have made access to the test range less predictable and less frequent than in the past. Finally, the Sarbanes-Oxley Act of 2002 required changes in, and formalization of, some of the Company’s corporate governance and compliance practices. The SEC and New York Stock Exchange (NYSE) also passed rules and regulations requiring additional compliance activities. Compliance with these rules has increased administrative costs, and it is expected that certain of these costs will continue indefinitely. A further discussion of the Company’s risk factors has been included in Part I, Item l(a), Risk Factors of this report. Management cautions readers not to place undue reliance on forward-looking statements, which are subject to influence by the enumerated risk factors as well as unanticipated future events.

The following discussion should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Item 8 of this report.

FISCAL 2006 COMPARED TO FISCAL 2005

		2006								2005
		Sales				% of Total				Sales				% of Total				% Change
Government		$	42,536,000				25	%		$	38,243,000				23	%			11	%
Industrial/Other			57,602,000				34				47,588,000				28				21

Totals		$	170,805,000				100	%		$	167,157,000				100	%			2	%

Sales for the year ended June 30, 2006, totaled $170,805,000 an increase of $3,648,000 (2%) from fiscal 2005. Government sales increased $4,293,000, primarily due to increased availability and access to the sonobuoy test range and accepted lots. Industrial sales, which includes gaming, improved significantly. This is reflective of continued strong sales to existing customers. Sales in the aerospace market decreased 23%, due principally to experiencing strong sales of collision avoidance systems in fiscal 2005, which level of sales were not expected to continue into fiscal 2006. We expect aerospace sales to expand in fiscal 2007. Medical sales improved from the prior year, primarily due to new program start-ups. In addition, the Company’s new acquisition, Astro, operates principally in the medical market. We expect sales in the medical market to expand. Total medical sales of $17,873,000 include $3,280,000 of sales contributed by Astro since acquisition, which occurred on May 31, 2006.

The majority of the Company’s sales come from a small number of customers. Sales to our six largest customers, including government sales, accounted for approximately 77% of net sales in both fiscal 2006 and 2005. Four of the customers, including government, were the same both years. One customer accounted for 20% and 13% of our sales in fiscal 2006 and 2005, respectively. Additionally, one other customer, with several facilities, provided 19% and 28% of our sales for the years ended June 30, 2006 and 2005, respectively.

The following table presents consolidated income statement data as a percentage of net sales for the years ended June 30, 2006 and 2005, respectively.

		2006				2005
Net sales			100.0	%			100.0	%

An operating loss of $1,918,000 was reported for the fiscal year ended June 30, 2006, compared to operating income of $10,264,000 for the fiscal year ended June 30, 2005. The results of Astro for the one month period ended June 30, 2006, did not have a significant impact on the Company’s fiscal 2006 results other than disclosed. The gross profit percentage for

		Sparton Corporation 2006 Annual Report			18

the year ended June 30, 2006, was 8.2%, down from 10.8% for the same period last year. Gross profit varies from period to period and can be affected by a number of factors, including product mix, production efficiencies, capacity utilization, and new product introduction, all of which impacted fiscal 2006 performance. Reflected in gross profit for the year ended June 30, 2006, were charges of $1,789,000 resulting from changes in estimates, primarily related to certain sonobuoy programs. Of these charges, $903,000 were incurred in the fourth quarter. These programs are now expected to be loss contracts and the Company recognized the entire estimated losses as of June 30, 2006. While some of these programs were completed and shipped by June 30 of this fiscal year, there is a backlog of $5.5 million which will be completed and shipped during fiscal 2007. These $5.5 million of sales will reflect no profit margin upon their sale due to their loss position. Included for the twelve months ended June 30, 2006, are the results from the Company’s new Vietnam facility, the start-up of which adversely impacted gross profit by $1.6 million. A number of new programs are scheduled to commence in Vietnam during the summer months of 2006. In addition, the prior year’s gross profit benefited by the inclusion of delayed government sales of $4.7 million. These sales carried a higher than usual margin, contributing $1.7 million in the first quarter of fiscal 2005, which sales the Company was unable to match in fiscal 2006. The current year’s reduced gross profit also includes several medical programs, which are operating in a loss or breakeven position due to their current status in the start-up phase. Two of these programs had negative margins which, for the year ended June 30, 2006, totaled $585,000, $269,000 of which occurred during the fourth quarter. The issues related to these losses are being addressed. Finally, discussions and resolution with a customer regarding the recovery of past material component costs, $183,000 of which were previously deferred in fiscal 2005, were not completed during the period and as a result, $378,000 was charged to expense during the year ended June 30, 2006. The Company is continuing its efforts to resolve this issue with the customer and fully recover these costs.

Selling and administrative expenses in fiscal 2006 included approximately $524,000 of litigation expenses related to the NRTC litigation, which is further discussed in Part II, Item 1 – Other Information-Legal Proceedings” of this report. In addition, beginning in fiscal 2006, the Company was required to expense the vested portion of the fair value of stock options. Share-based compensation expense recorded for the year ended June 30, 2006, totaled $344,000, approximately 84% of which, or $290,000, is included in selling and administrative expense. Additional costs are also being incurred as a result of compliance activity due to increased SEC and other regulatory requirements. These compliance costs have increased in several areas, both internally and externally. In addition to increased audit fees and other costs, the Company has outsourced some of the new compliance efforts to a consulting firm, resulting in additional costs of $272,000 during the year ended June 30, 2006. The remainder of the increase in selling and administrative expenses relates to minor and expected increases in various categories, such as wages, employee benefits, insurance, and other items.

Operating income also includes charges related to the New Mexico environmental remediation effort, principally legal fees, of $65,000 in fiscal 2006 and $424,000 in fiscal 2005. In addition, fiscal 2005 includes $5,455,000 (pre-tax) of income related to the Company’s settlement with previous insurance carriers, which reflects a recovery of a portion of past costs the Company incurred in its investigation and site remediation of its Coors Road facility. These EPA charges and income are more fully discussed in Note 10 to the Consolidated Financial Statements included in Item 8. Net gain on sale of property, plant and equipment in fiscal 2005 included a gain of $397,000 on the sale of a warehouse in DeLeon Springs, Florida.

Interest and investment income increased $225,000 to $1,116,000 in fiscal 2006. This increase was due to increased funds available for investment during the year and improved investment rates. Investment securities are more fully described in Note 3 to the Consolidated Financial Statements included in Item 8. Interest expense of $98,000 in fiscal 2006 is a result of the debt incurred and acquired in the acquisition of Astro. A complete discussion of debt is contained in Note 9 to the Consolidated Financial Statements included in Item 8. Other income (expense) – net was $583,000 and $221,000 in fiscal 2006 and 2005, respectively. Other-net in fiscal 2006 and 2005 includes $586,000 and $228,000, respectively, of net translation and transaction gains.

Equity investment income (loss) was $21,000 and ($15,000) in fiscal 2006 and 2005, respectively. Included in the equity investments is the Company’s investment in Cybernet Systems Corporation (Cybernet), representing a 14% ownership interest.

The Company’s effective tax rate (benefit) for fiscal 2006 was (133%) compared to the statutory U.S. federal tax rate of 34%. A complete discussion of the elements of the tax provision is contained in Note 7 to the Consolidated Financial Statements included in Item 8.

After provision for applicable income taxes the Company reported net income of $98,000 ($0.01 per share, basic and diluted) in fiscal 2006, compared to net income of $8,112,000 ($0.88 per share; $0.87 diluted) in fiscal 2005. Fiscal 2005 results include income of $5,455,000 related to the EPA settlement (approximately $3,895,000 net of tax).

Sales for the year ended June 30, 2005, totaled $167,157,000, an increase of $6,153,000 (4%) from fiscal 2004. Government sales decreased, and included $4.7 million of a delayed sonobuoy sale originally anticipated to ship in fiscal 2004. Rescheduling of engineering redesign work, failed sonobuoy drop tests, and lack of access to the U.S. Navy’s test site contributed to the depressed government sales. Industrial and other market sales, which include gaming sales, increased from the same period last year. This increase was attributed to increased demand from two existing customers. Sales to the aerospace markets continued to grow, increasing 17% over the prior year. In general, this reflected stronger demand in the commercial aerospace market, primarily increased demand for products related to aircraft collision avoidance systems mandated for installation in all commercial aircraft. Approximately $2 million of the aerospace increase was attributable to increased orders from one customer, to which the Company supplies product to several separate manufacturing facilities. Medical/Scientific Instrumentation sales declined from the prior year. This decrease resulted from overall lower demand from existing customers in this market area, as well as new program delays.

Sales to our six largest customers, including government sales, accounted for approximately 77% and 74% of net sales in fiscal 2005 and 2004, respectively. Five of the customers, including government, were the same both years. One of these customers, with six separate facilities as discussed above, provided 28% and 25% of the sales for the years ended June 30, 2005 and 2004, respectively.

The following table presents consolidated income statement data as a percentage of net sales for the years ended June 30, 2005 and 2004, respectively.

Operating income of $10,264,000 was reported for the fiscal year ended June 30, 2005, compared to a loss of $4,307,000 for the fiscal year ended June 30, 2004. Gross profit percentage for the year was 10.8%, up from 5.8% in the prior year. Results for fiscal 2005 were impacted by severe tropical storms in Florida during the period. While the tropical storms largely bypassed the Company’s two Florida facilities, extensive preparations were undertaken for the predicted storms. This unexpected activity, along with the minor damage that was experienced and unproductive wages, resulted in costs of

		Sparton Corporation 2006 Annual Report			20

approximately $500,000 being charged in the first quarter of fiscal 2005, the majority of which were included in cost of goods sold. Fiscal 2005’s gross profit also included a settlement with a customer in the second quarter of fiscal 2005, which resulted in the Company’s recovery of $500,000 of prior period start-up expenses. Fiscal 2004’s depressed margin reflects the inclusion of costs on the start-up phase of several major programs, as well as final charges incurred at the completion of one sonobuoy contract that had experienced technical problems. In addition, fiscal 2004’s margin included a redesign effort on an existing product line, which resulted in a charge to operations of $519,000. Gross margin was further reduced in 2005 and 2004 by charges of $609,000 and $1,021,000, respectively, for obsolete inventory at two locations. The Company continued to experience underutilized capacity which, due to the fixed nature of many of the Company’s costs, continued to negatively impact margins. Finally, pension costs decreased $247,000, to $480,000 in fiscal 2005 from $727,000 in fiscal 2004. This decrease in pension costs was due to an increase in the expected return on pension assets and reduced amortization costs related to unrecognized actuarial losses. The majority of pension costs are charged to cost of goods sold. Spartronics Vietnam officially began operations in May 2005. Included in fiscal 2005 results were the operations from the Company’s new Vietnam facility, which startup adversely impacted gross margin by $1,600,000.

The lowered selling and administrative expenses were primarily the result of decreased bid and proposal and research and development expenses for fiscal 2005, which were approximately $2 million below prior year. These cost reductions were not indicative of reduced bid and proposal activity, but primarily the result of a one time sonobuoy engineering project in fiscal 2004 which has been completed.

Operating income also includes charges related to the New Mexico environmental remediation effort, principally legal fees, of $424,000 in fiscal 2005 and $321,000 in fiscal 2004. In addition, fiscal 2005 includes $5,455,000 (pre-tax) of income related to the Company’s settlement with previous insurance carriers, which reflected a recovery of a portion of past costs the Company incurred in its investigation and site remediation of its Coors Road facility. EPA charges and income are more fully discussed in Note 10 to the Consolidated Financial Statements included in Item 8. Net gain on sale of property, plant and equipment in fiscal 2005 includes a gain of $397,000 on the sale of a warehouse in DeLeon Springs, Florida. Fiscal 2004 includes a gain of $844,000 related to the disposal of the Rio Rancho plant, which was replaced by the current Albuquerque, New Mexico facility.

In the fourth quarter of fiscal 2005, the Company also settled negotiations with a Canadian customer for past costs and inventory. This settlement resulted in the receipt of approximately $1 million cash, with a loss recognized of approximately $347,000. Most of this inventory had previously been carried as a long-term asset in the Company’s balance sheet.

Interest and investment income increased $175,000 to $892,000 in fiscal 2005. This increase was due to increased funds available for investment and improved investment rates. Investment securities are more fully described in Note 3 to the Consolidated Financial Statements included in Item 8. Other income (expense) – net was $221,000 and $(604,000) in fiscal 2005 and 2004, respectively. Other-net in fiscal 2004 includes $598,000 of costs related to an insurance adjustment for the Company’s previously owned automotive segment. These charges were for a previously disputed claim, which has been settled. Other-net in fiscal 2005 and 2004 includes $228,000 and $5,000, respectively, of net translation and transaction gains.

Equity investment loss was $15,000 in fiscal 2005, compared to income of $14,000 in fiscal 2004. Included in the equity investments is the Company’s investment in Cybernet Systems Corporation (Cybernet), representing a 14% ownership interest, which was acquired in June 1999.

The Company’s effective tax rate for fiscal 2005 was 29%, compared to the statutory U.S. federal tax rate of 34%. A complete discussion of the elements of the tax provision is contained in Note 7 to the Consolidated Financial Statements included in Item 8. After provision for applicable income taxes, the Company reported a net profit of $8,112,000 ($0.88 per share; $0.87 diluted) in fiscal 2005, compared to a net loss of $2,043,000 ($(0.22) per share; basic and diluted) in fiscal 2004.

LIQUIDITY AND CAPITAL RESOURCES

The primary source of liquidity and capital resources has historically been generated from operations. Certain government contracts provide for interim progress billings based on costs incurred. These progress billings reduce the amount of cash that would otherwise be required during the performance of these contracts. As the volume of U.S. defense-related contract work has declined over the past several years, so has the relative importance of progress billings as a liquidity resource. At the present time, the Company plans on using its investment securities to provide working capital, invest in additional property, plant and equipment, and to strategically accommodate growth. Growth is expected to be achieved through internal expansion and/or acquisition or joint venture. In addition, the Company’s previously announced $4,000,000 stock repurchase program is expected to utilize a portion of the Company’s investments. Through June 30, 2006, approximately 39,000 shares, at a cost of approximately $363,000, have been repurchased. These repurchased shares have been retired.

For the fiscal year ended June 30, 2006, cash and cash equivalents decreased $1,865,000 to $7,503,000. Operating activities provided $7,992,000, $6,547,000 and $1,028,000 in fiscal 2006, 2005 and 2004, respectively, in net cash flows. The primary source of cash in fiscal 2006 resulted from the receipt of $5,455,000 in cash from a legal settlement, which occurred in fiscal 2005. Additionally, collection of receivables, reflective of the high amount of sales in June of fiscal 2005, also contributed to cashflow. The primary use of cash in fiscal 2006 was a net settlement in accounts payable and accrued liabilities. The change in this area between fiscal 2006 and 2005 is primarily due to the payment of $2.4 million in income taxes payable from fiscal 2005, as well as payment for the increase in inventory and other liabilities recorded at June 30, 2005. The primary source of cash in 2005 was from operations, after reduction for the non-cash income related to a legal settlement, plus the increase in accounts payable and other accruals. Partially offsetting this was an increase in accounts receivable reflecting higher government sales in June 2005. The legal settlement resulted in the Company’s recognition of $5,455,000 of income, the receipt of which occurred in July 2005. The primary source of cash in fiscal 2004, which reflected a net loss, was from collection of accounts receivable. The fiscal 2004 decrease in accounts receivable was reflective of the receipt of payments for the large volume of sales recognized in June 2003. The change in cash flow related to inventory and prepaid expenses between fiscal 2005 and 2004 was reflective of a large increase at June 30, 2004 of inventory due to delayed customer delivery schedules, as well as increased inventory for new customer contracts. Inventory levels at June 30, 2005, reflected a decline, as these customers’ schedules were no longer delayed, as well as the start of several new customer contracts. In fiscal 2005, the increase in accounts payable and accrued liabilities was primarily due to income taxes payable. In fiscal 2004, the Company, due to its loss position, recorded an income tax receivable. Fiscal 2005 cash flow from operations also includes an “other” net reduction of $1,185,000 including two separate transactions. The first, reflecting a reduction in operating cash flow, relates to a claim for an amount due of $2,884,000 in fiscal 2006, an increase of $487,000 from fiscal 2005, from a vendor for defective circuit boards supplied to us, the resolution of which the Company is currently pursuing with the board’s manufacturer. This amount, reflecting prior accounts receivable and inventory and associated expenses, is included in other long-term assets. The second, reflecting an increase in operating cash flow, includes a $1,212,000 settlement and collection from a customer for past costs and inventory which, due to the age of the claim, had been included in other long-term assets.

Cash flows used by investing activities totaled $19,304,000, $8,300,000 and $808,000 in fiscal 2006, 2005 and 2004, respectively. Cash was primarily used for the purchase of Astro, as well as the purchase of property, plant and equipment, which is discussed below. Included in the Company’s balance sheet as of June 30, 2006, is construction in progress of approximately $300,000 towards the construction of Astro’s new 20,000 square foot addition. Total cost for this expanded production space is anticipated to be $1.7 million. The purchase of, and proceeds from the sale and maturities of, investment securities are generally reflective of activity within the various investment options, with the net purchases position representing the investment of excess cash generated from operations in fiscal 2005. In fiscal 2006, net proceeds from the sale and maturities of investments were also used to fund the Astro acquisition. In fiscal 2005 and 2004, net proceeds from the sale and maturities of investments were also used to fund purchases of property, plant and equipment.

Cash flows provided by financing activities were $9,447,000, $300,000, and $39,000 in fiscal 2006, 2005 and 2004, respectively, primarily in fiscal 2006 from the issuance of debt related to the acquisition of Astro, and reflecting in all three fiscal years presented the exercise of stock options. Cash flows used by financing activity in fiscal 2006 were primarily from the repurchase of Company stock and the payment of a $0.10 per share cash dividend which is further discussed below.

Historically, the Company’s market risk exposure to foreign currency exchange and interest rates on third party receivables and payables has not been considered to be material, principally due to their short-term nature and the minimal amount of receivables and payables designated in foreign currency. However, due to the strengthened Canadian dollar, the impact of transaction and translation gains on intercompany activity and balances has increased. If the exchange rate were to materially change, the Company’s financial position could be significantly affected. The Company currently has an unused formal line of credit totaling $20 million and a bank loan totaling $10 million. In addition, there are notes payable totaling $7.5 million outstanding to the former owners of Astro. These borrowings are discussed below.

		Sparton Corporation 2006 Annual Report			22

At June 30, 2006 and 2005, the aggregate government funded EMS backlog was approximately $41 million and $42 million, respectively. A majority of the June 30, 2006, backlog is expected to be realized in the next 12-15 months. Commercial EMS orders are not included in the backlog. The Company does not believe the amount of commercial activity covered by firm purchase orders is a meaningful measure of future sales, as such orders may be rescheduled or cancelled without significant penalty.

The Company signed a membership purchase agreement and completed the acquisition of Astro on May 31, 2006. Astro’s sales volume for the year ended December 31, 2005, was approximately $34 million. The purchase price was approximately $26.15 million, plus the extinguishment by Sparton at closing of $4.2 million in seller credit facilities and the assumption of $2.3 million in bonded debt. The purchase price was funded using a combination of cash, $10 million in bank debt, and $7.5 million in notes payable to Astro’s previous owners (sellers). Additional contingent consideration may be paid to the sellers over the four years based on 20% of Astro’s earnings before interest, depreciation, and taxes as defined, and if paid will be added to goodwill. Under the terms of the purchase agreement, the prior owners entered into non-competition agreements with the Company. Astro is an EMS provider that designs and manufactures a variety of specialized medical products, generally involving high-quality medical laboratory test equipment. Astro operates from a 40,000 square foot facility in an industrial park. A 20,000 square foot addition to the facility is now under construction. Sparton now operates the business as a wholly-owned subsidiary at its present location and with the current operating management and staff. A further discussion of the Astro purchase is contained in Notes 9 and 13 to the Consolidated Financial Statements included in Item 8. The Company is continuing a program of identifying and evaluating potential acquisition candidates in both the defense and medical markets.

Construction of the Company’s Spartronics’ plant in Vietnam was completed and production began in May 2005. This facility is anticipated to provide increased growth opportunities for the Company, in current as well as new markets. As the Company has not previously done business in this emerging market, there are many uncertainties and risks inherent in this venture. To date, the Company’s total investment approximates $6 million, which includes land, building, and initial operating expenses, with approximately $3 million having been expended for the construction of the new facility, primarily in fiscal 2005. As with the Company’s other facilities, the majority of the equipment utilized in production operations is leased.

The Company purchased a manufacturing facility in Albuquerque, New Mexico in December 2003 for approximately $4.5 million. This facility replaced an existing plant in Rio Rancho, New Mexico. The costs of remodeling and facility upgrades approximated $2 million and were incurred, primarily in 2005, as the Company transitioned between facilities. The Rio Rancho plant was sold in June 2004 for approximately $1.7 million ($1.6 million after expenses related to the sale), resulting in a $844,000 gain. The Company leased the Rio Rancho facility until the transition to the new facility was completed in December 2004. The new facility provides a much more efficient manufacturing space.

In the first quarter of fiscal 2006, a $0.10 per share cash dividend, totaling approximately $889,000, was paid to shareowners on October 5, 2005. Subsequently in October 2005, the Company declared a 5% stock dividend. This dividend was distributed January 13, 2006, to shareowners of record on December 21, 2005. At June 30, 2006, the Company had $96,850,000 in shareowners’ equity ($10.31 per share), $68,197,000 in working capital, and a 3.17:1.00 working capital ratio. The Company believes it has sufficient liquidity for its anticipated needs over the next 12-18 months, unless an additional significant business acquisition were to be identified and completed for cash.

CONTRACTUAL OBLIGATIONS

The Company’s current obligations, which are due within twelve months, for the payment of accounts payable, accruals, and other liabilities totaled $31,401,000 at June 30, 2006, and includes the $3,816,000 and $491,000, respectively, for the current portions of our long-term debt and environmental liability, respectively, and $505,000 of the standby letters of credit. These obligations are reflected in the Consolidated Balance Sheets in Item 8. The following tables summarize the Company’s significant contractual obligations and other commercial commitments as of June 30,2006:

Long-term debt — Payments include principal and interest for both short-term and long-term debt, including a $10 million bank loan, notes totaling $7.5 million payable to the previous owners of Astro, and Industrial Revenue bond obligations, which were assumed by Sparton at the time of purchase. See Note 9 to the consolidated financial statements included in Item 8 of this report for further discussion on borrowings.

Operating leases — See Note 8 to the Consolidated Financial Statements included in Item 8 of this report for further discussion of operating leases.

Environmental liabilities — See Note 10 to the Consolidated Financial Statements included in Item 8 of this report for a description of the accrual for environmental remediation. Of the $6,287,000 total accrued, $491,000 is classified as a current liability and $5,796,000 is classified as a long-term liability, both of which are included on the balance sheet as of June 30, 2006.

Noncancelable purchase orders — Binding orders the Company has placed with suppliers that are subject to quality and performance requirements.

Standby letters of credit — The Company has standby letters of credit outstanding of approximately $990,000 at June 30, 2006, principally to support self-insured programs, certain foreign sales contracts, and a portion of the Industrial Revenue bonds assumed from Astro. Approximately $505,000 of the potential liabilities related to these letters of credit are reflected as accrued liabilities on the Company’s June 30, 2006 balance sheet.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates, judgments and assumptions that affect the amounts reported as assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Estimates are regularly evaluated and are based on historical experience and on various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management’s judgment in application. There are also areas in which management’s judgment in selecting among available alternatives would not produce a materially different result. The Company believes that of its significant accounting policies as discussed in Note 1 included to the Consolidated Financial Statements, which is included in Item 8, the following involve a higher degree of judgement and complexity. Senior management has reviewed these critical accounting policies and related disclosures with Sparton’s audit committee of the Board of Directors.

Environmental Contingencies

One of Sparton’s former manufacturing facilities, located in Albuquerque, New Mexico (Coors Road), has been the subject of ongoing investigations and remediation efforts conducted with the Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA). As discussed in Note 10 to the Consolidated Financial Statements included in Item 8, Sparton has accrued its estimate of the minimum future non-discounted financial liability. The estimate was developed using existing technology and excludes legal and related consulting costs. The minimum cost estimate includes equipment, operating and monitoring costs for both onsite and offsite remediation. Sparton recognizes legal and consulting services in the periods incurred and reviews its EPA accrual activity quarterly. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. It is possible that cash flows and results of operations could be materially affected by the impact of changes in these estimates.

Government Contract Cost Estimates

Government production contracts are accounted for based on completed units accepted with respect to revenue recognition and their estimated average cost per unit regarding costs. Losses for the entire amount of the contract are recognized in the period when such losses are determinable. Significant judgment is exercised in determining estimated total contract costs including, but not limited to, cost experience to date, estimated length of time to contract completion, costs for materials, production labor and support services to be expended, and known issues on remaining units to be completed. In addition, estimated total contract costs can be significantly affected by changing test routines and procedures, resulting

		Sparton Corporation 2006 Annual Report			24

design modifications and production rework from these changing test routines and procedures, and limited range access for testing these design modifications and rework solutions. Estimated costs developed in the early stages of contracts can change, sometimes significantly, as the contracts progress, and events and activities take place. Changes in estimates can also occur when new designs are initially placed into production. The Company formally reviews its costs incurred-to-date and estimated costs to complete on all significant contracts at least quarterly and revised estimated total contract costs are reflected in the financial statements. Depending upon the circumstances, it is possible that the Company’s financial position, results of operations and cash flows could be materially affected by changes in estimated costs to complete on one or more significant contracts.

Commercial Inventory Valuation Allowances

Inventory valuation allowances for commercial customer inventories require a significant degree of judgment and are influenced by the Company’s experience to date with both customers and other markets, prevailing market conditions for raw materials, contractual terms and customers’ ability to satisfy these obligations, environmental or technological materials obsolescence, changes in demand for customer products, and other factors resulting in acquiring materials in excess of customer product demand. Contracts with some commercial customers may be based upon estimated quantities of product manufactured for shipment over estimated time periods. Raw material inventories are purchased to fulfill these customer requirements. Within these arrangements, customer demand for products frequently changes, sometimes creating excess and obsolete inventories.

The Company regularly reviews raw material inventories by customer for both excess and obsolete quantities, with adjustments made accordingly. Wherever possible, the Company attempts to recover its full cost of excess and obsolete inventories from customers or, in some cases, through other markets. When it is determined that the Company’s carrying cost of such excess and obsolete inventories cannot be recovered in full, a charge is taken against income and a valuation allowance is established for the difference between the carrying cost and the estimated realizable amount. Conversely, should the disposition of adjusted excess and obsolete inventories result in recoveries in excess of these reduced carrying values, the remaining portion of the valuation allowances are reversed and taken into income when such determinations are made. It is possible that the Company’s financial position, results of operations and cash flows could be materially affected by changes to inventory valuation allowances for commercial customer excess and obsolete inventories.

Allowance for Probable Losses on Receivables

The accounts receivable balance is recorded net of allowances for amounts not expected to be collected from customers. The allowance is estimated based on historical experience of write-offs, the level of past due amounts, information known about specific customers with respect to their ability to make payments, and future expectations of conditions that might impact the collectibility of accounts. Accounts receivable are generally due under normal trade terms for the industry. Credit is granted, and credit evaluations are periodically performed, based on a customer’s financial condition and other factors. Although the Company does not generally require collateral, cash in advance or letters of credit may be required from customers in certain circumstances, including some foreign customers. When management determines that it is probable that an account will not be collected, it is charged against the allowance for probable losses. The Company reviews the adequacy of its allowance monthly. The allowance for doubtful accounts was $67,000 and $6,000 at June 30, 2006 and 2005, respectively. If the financial condition of customers were to deteriorate, resulting in an impairment of their ability to make payment, additional allowances may be required. Given the Company’s significant balance of government receivables and letters of credit from foreign customers, collection risk is considered minimal. Historically, uncollectible accounts have generally been insignificant and the minimal allowance is deemed adequate.

Pension Obligations

The Company calculates the cost of providing pension benefits under the provisions of Statement of Financial Accounting Standards (SFAS) No. 87, Employers’ Accounting for Pensions. The key assumptions required within the provisions of SFAS No. 87 are used in making these calculations. The most significant of these assumptions are the discount rate used to value the future obligations and the expected return on pension plan assets. The discount rate is consistent with market interest rates on high-quality, fixed income investments. The expected return on assets is based on long-term returns and assets held by the plan, which is influenced by historical averages. If actual interest rates and returns on plan assets materially differ from the assumptions, future adjustments to the financial statements would be required. While changes in these assumptions can have a significant effect on the pension benefit obligation and the unrecognized gain or loss accounts disclosed in the Notes to the Financial Statements, the effect of changes in these assumptions is not expected to have the same relative effect on net periodic pension expense in the near term. While these assumptions may change in the future based on changes in long-term interest rates and market conditions, there are no known expected changes in these assumptions as of June 30, 2006. As indicated above, to the extent the assumptions differ from actual results or if there are changes made to accounting standards for these costs, there would be a future impact on the financial statements. The extent to which this

		Sparton Corporation 2006 Annual Report			25

will result in future expense is not determinable at this time as it will depend upon a number of variables, including trends in interest rates and the actual return on plan assets. During the quarter ended March 31, 2006, the annual actuarial valuation of the pension plan was completed. Based on this valuation, net periodic pension expense for fiscal 2006 was determined to be $548,000 compared to $480,000 for fiscal 2005. The components of net periodic pension expense are detailed in Note 6 to the Consolidated Financial Statements included in Item 8 of this report. No cash payments are expected to be required prior to 2008 due to the plan’s funded status.

Business Combinations

In accordance with accepted business combination accounting, the Company allocated the purchase price of its recent Astro acquisition to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The Company engaged an independent, third-party appraisal firm to assist management in determining the fair value of certain assets acquired and liabilities assumed. Such valuations require management to make significant estimates, judgments and assumptions, especially with respect to intangible assets.

Management arrived at estimates of fair value based upon assumptions believed to be reasonable. These estimates are based on historical experience and information obtained from the management of the acquired business and are inherently uncertain. Critical estimates in valuing certain of the intangible assets include but are not limited to: future expected discounted cash flows from customer relationships and contracts assuming similar product platforms and completed projects; the acquired company’s market position, as well as assumptions about the period of time the acquired customer relationships will continue to generate revenue streams; and attrition and discount rates. Unanticipated events and circumstances may occur which may affect the accuracy or validity of such assumptions, estimates or actual results, particularly with respect to amortization periods assigned to identifiable intangible assets.

Goodwill and Customer Relationships

The Company currently reviews goodwill associated with its Cybernet investment on a regular basis for possible impairment. Additionally, the Company will review goodwill and customer relationships, associated with the recent Astro acquisition, for impairment annually, with the first review anticipated to occur in April 2007. Possible impairment of these assets will also be reviewed should events or changes in circumstances indicate their carrying value may not be recoverable in accordance with SFAS No. 142, Goodwill and Other Intangible Assets. The provisions of SFAS No. 142 require that a two-step impairment test be performed on intangible assets. In the first step, the Company compares the fair value of each reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to the unit, goodwill is considered not impaired and the Company is not required to perform further testing. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, then management will perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, then the Company would record an impairment loss equal to the difference.

Determining the fair value of any reporting entity is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include revenue growth rates, operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and, if appropriate, determination of appropriate market comparables. The Company bases its fair value estimates on assumptions believed to be reasonable, but which are unpredictable and inherently uncertain. Actual future results may differ from those estimates. In addition, the Company makes certain judgments and assumptions in allocating shared assets and liabilities to determine the carrying values for each of the Company’s reporting units. The most recent annual goodwill impairment analysis related to the Company’s Cybernet investment, which was performed during the fourth quarter of fiscal 2006, did not result in an impairment charge.

OTHER

Litigation

One of Sparton’s facilities, located in Albuquerque, New Mexico, has been the subject of ongoing investigations conducted with the Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA). The investigation began in the early 1980’s and involved a review of onsite and offsite environmental impacts.

At June 30, 2006, Sparton has accrued $6,287,000 as its estimate of the future undiscounted minimum financial liability with respect to this matter. The Company’s cost estimate is based upon existing technology and excludes legal and related consulting costs, which are expensed as incurred, and is anticipated to cover approximately the next 24 years. The Company’s estimate includes equipment and operating costs for onsite and offsite operations and is based on existing methodology.

		Sparton Corporation 2006 Annual Report			26

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. It is possible that cash flows and results of operations could be affected significantly by the impact of the ultimate resolution of this contingency.

Some of the printed circuit boards supplied to the Company for its aerospace sales have been discovered to be defective. The defect occurred during production at the raw printed circuit board suppliers facility, prior to shipment to Sparton for further processing. Sparton; the board manufacturer, Electropac Co., Inc.; and our customer, who received the defective boards, have contained the defective boards. While investigations are underway, $2.9 million of related product and associated expenses have been classified in Sparton’s balance sheet within other long-term assets as of June 30, 2006. In August 2005, Sparton Electronics Florida, Inc. filed an action in U.S. District Court of Florida against Electropac Co., Inc. to recover these costs. The likelihood that the claim will be resolved and the extent of Sparton’s exposure, if any, is unknown at this time. No loss contingency has been established at June 30, 2006.

Sparton is currently involved with legal actions, which are disclosed in Part I Item 3 – “Legal Proceedings”, of this report. At this time, the Company is unable to predict the outcome of these claims.

Item 7(a). Quantitative and Qualitative Disclosures About Market Risk

MARKET RISK EXPOSURE

The Company manufactures its products in the United States, Canada, and Vietnam. Sales are to the U.S. and Canada, as well as other foreign markets. The Company is potentially subject to foreign currency exchange rate risk relating to intercompany activity and balances and to receipts from customers and payments to suppliers in foreign currencies. Also, adjustments related to the translation of the Company’s Canadian and Vietnamese financial statements into U.S. dollars are included in current earnings. As a result, the Company’s financial results could be affected by factors such as changes in foreign currency exchange rates or economic conditions in the domestic and foreign markets in which the Company operates. However, minimal third party receivables and payables are denominated in foreign currency and the related market risk exposure is considered to be immaterial. Historically, foreign currency gains and losses related to intercompany activity and balances have not been significant. However, due to the strengthened Canadian dollar, the impact of transaction and translation gains has increased. If the exchange rate were to materially change, the Company’s financial position could be significantly affected.

The Company has financial instruments that are subject to interest rate risk, principally short-term investments. Historically, the Company has not experienced material gains or losses due to such interest rate changes. Based on the current holdings of short-term investments, the interest rate risk is not considered to be material.

Item 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareowners of Sparton Corporation

We have audited the accompanying consolidated balance sheets of Sparton Corporation and subsidiaries as of June 30, 2006 and 2005, and the related consolidated statements of income, shareowners’ equity and cash flows for each of the three years in the period ended June 30, 2006. Our audits also included the financial statement schedule listed in the index at Item 15(a)2. These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and schedule, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and schedule. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Sparton Corporation and subsidiaries as of June 30, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended June 30, 2006, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the financial statement schedule presents fairly, in all material respects, the information set forth therein.

SPARTON CORPORATION AND SUBSIDIARIES
Notes to Consolidated Financial Statements

1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation — The consolidated financial statements include the accounts of Sparton Corporation and subsidiaries (the Company) and have been prepared in accordance with accounting principles generally accepted in the United States of America. All significant intercompany transactions and accounts have been eliminated. Certain reclassifications of prior year amounts have been made to conform to the current year presentation.

Operations — The Company operates in one line of business, electronic manufacturing services (EMS). The Company provides design and electronic manufacturing services, which include a complete range of engineering, pre-manufacturing and post-manufacturing services. Capabilities range from product design and development through aftermarket support. All of the facilities are registered to ISO standards, including 9001 or 13485, with most having additional certifications. Products and services include complete “Box Build” products for Original Equipment Manufacturers, microprocessor-based systems, transducers, printed circuit boards and assemblies, sensors and electromechanical devices. Markets served are in the government, medical/scientific instrumentation, aerospace, and other industries, with a focus on regulated markets. The Company also develops and manufactures sonobuoys, anti-submarine warfare (ASW) devices, used by the U.S. Navy and other free-world countries. Many of the physical and technical attributes in the production of sonobuoys are the same as those required in the production of the Company’s other electrical and electromechanical products and assemblies.

Use of estimates — The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). These accounting principles require management to make certain estimates, judgments and assumptions. The Company believes that the estimates, judgments and assumptions upon which it relies are reasonable based upon information available to it at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are material differences between these estimates, judgments or assumptions and actual results, the financial statements will be affected. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting among available alternatives would not produce a materially different result.

Revenue recognition — The Company’s net sales are comprised primarily of product sales, with supplementary revenues earned from engineering and design services. Standard contract terms are FOB shipping point. Revenue from product sales is generally recognized upon shipment of the goods; service revenue is recognized as the service is performed or under the percentage of completion method, depending on the nature of the arrangement. Long-term contracts relate principally to government defense contracts. These contracts are accounted for based on completed units accepted and their estimated average contract cost per unit. Costs and fees billed under cost-reimbursement-type contracts are recorded as sales. A provision for the entire amount of a loss on a contract is charged to operations as soon as the loss is identified and the amount is determinable. Shipping and handling costs are included in costs of goods sold.

Accounts receivable, credit practices, and allowance for probable losses — Accounts receivable are customer obligations generally due under normal trade terms for the industry. Credit terms are granted and periodically revised based on evaluations of the customers’ financial condition. The Company performs ongoing credit evaluations of its customers and although the Company does not generally require collateral, letters of credit or cash advances may be required from customers in certain circumstances. Receivables from foreign customers are generally secured by letters of credit or cash advances.

The Company maintains an allowance for probable losses on receivables for estimated losses resulting from the inability of its customers to make required payments. The allowance is estimated based on historical experience of write-offs, the level of past due amounts (i.e., amounts not paid within the stated terms), information known about specific customers with respect to their ability to make payments, and future expectations of conditions that might impact the collectibility of accounts. When management determines that it is probable that an account will not be collected, all or a portion of the amount is charged against the allowance for probable losses.

Fair value of financial instruments — The fair value of cash and cash equivalents, trade accounts receivable, and accounts payable approximate their carrying value. Cash and cash equivalents consist of demand deposits and other highly liquid investments with an original term when purchased of three months or less. Due to the recent addition of the debt instruments, consisting of industrial revenue bonds, notes payable and bank debt, relating to the May 31, 2006 acquisition of Astro Instrumentation, LLC, as documented in Note 13, the fair value of these financial instruments approximates their carrying value at June 30, 2006.

Investment securities — Investments in debt securities that are not cash equivalents or marketable equity securities have been designated as available for sale. Those securities, all of which are investment grade, are reported at fair value, with net unrealized gains and losses included in accumulated other comprehensive income or loss, net of applicable taxes. Unrealized losses that are other than temporary are recognized in earnings. The investment portfolio has various maturity dates up to 30 years. Realized gains and losses on investments are determined using the specific identification method.

Other investment — The Company has an active investment in Cybernet Systems Corporation, which is accounted for under the equity method, as more fully described in Note 3.

Market risk exposure — The Company manufactures its products in the United States, Canada, and Vietnam. Sales of the Company’s products are in the U.S. and Canada, as well as other foreign markets. The Company is potentially subject to foreign currency exchange rate risk relating to intercompany activity and balances, receipts from customers, and payments to suppliers in foreign currencies. Also, adjustments related to the translation of the Company’s Canadian and Vietnamese financial statements into U.S. dollars are included in current earnings. As a result, the Company’s financial results could be affected by factors such as changes in foreign currency exchange rates or economic conditions in the domestic and foreign markets in which the Company operates. However, minimal third party receivables and payables are denominated in foreign currency and the related market risk exposure is considered to be immaterial. Historically, foreign currency gains and losses related to intercompany activity and balances have not been significant. However, due to the strengthened Canadian dollar, the impact of transaction and translation gains has increased. If the exchange rate were to materially change, the Company’s financial position could be significantly affected.

The Company has financial instruments that are subject to interest rate risk, principally short-term investments. Historically, the Company has not experienced material gains or losses due to such interest rate changes. Based on the current holdings of short-term investments, the interest rate risk is not considered to be material. In addition, as of May 31, 2006, the Company has bank debt with an adjustable rate of interest, as more fully discussed in Note 9, which would adversely impact operations should the interest rate increase.

Inventories — Customer orders are based upon forecasted quantities of product, manufactured for shipment over defined periods. Raw material inventories are purchased to fulfill these customer requirements. Within these arrangements, customer demand for products frequently change, sometimes creating excess and obsolete inventories. When it is determined that the Company’s carrying cost of such excess and obsolete inventories cannot be recovered in full, a charge is taken against income and a valuation allowance is established for the difference between the carrying cost and the estimated realizable amount. Conversely, should the disposition of adjusted excess and obsolete inventories result in recoveries in excess of these reduced carrying values, the remaining portion of the valuation allowances are reversed and taken into income when such determinations are made. It is possible that the Company’s financial position, results of operations and cash flows could be materially affected by changes to inventory valuation allowances for excess and obsolete inventories.

Inventories are valued at the lower of cost (first-in, first-out basis) or market and include costs related to long-term contracts as disclosed in Note 4. Inventories, other than contract costs, are principally raw materials and supplies. The following are the approximate major classifications of inventory at June 30:

		2006				2005
Raw materials		$	29,388,000			$	23,463,000
Work in process and finished goods			17,504,000				13,384,000
		$	46,892,000			$	36,847,000
