PART I



ITEM 1.
        Business




IntriCon Corporation, formerly Selas Corporation of America (together with its subsidiaries referred herein as the Company)is an international firm engaged in the design, development, engineering and manufacturing of micro-miniature components, systems and molded plastic parts primarily for the hearing instrument, electronics, telecommunications, computer and medical equipment industries. The Company, headquartered in Arden Hills, Minnesota has facilities in Minnesota, California, Singapore, and Germany, and operates directly or through subsidiaries. Within discontinued operations, the Company had facilities in Pennsylvania, Japan and Germany. The Company is a Pennsylvania corporation that was founded in 1930.



Currently, the Company has one operating segment, its precision miniature medical and electronics products segment. In the past, the Company had operated in three segments: precision miniature medical and electronics products segment, heat technology segment, and tire holders, lifts and related products segment. Since 2001, the Company began focusing on its precision miniature medical and electronics products segment and developing plans to exit the businesses that comprised the heat technology segment, and tire holders, lifts and related products segment. The Company exited the tire holders, lifts and related products business in 2003 and the heat technology segment in the first quarter of 2005. For all periods presented, the Company classified its heat technology segment as discontinued operations.



Major Events in 2006

In June 2006, the Company completed a sale-leaseback of the Vadnais Heights manufacturing facility. The transaction generated proceeds of $2,650,000, of which $1,388,000 was used to repay the associated real estate loan and the remainder to pay down the Companys domestic revolver. The gain on the sale of $1,045,799 will be recognized over the initial 10-year lease term as the renewal options in the lease are not assured and a penalty does not exist if the Company does not exercise the renewal options.



In the fourth quarter of 2006, the Company joined the Hearing Instrument Manufacturers Patent Partnership (HIMPP). Members of the partnership include the largest six hearing aid manufacturers as well as several other smaller manufacturers.  The purchase price of $1,800,000 includes an equity interest in K/S HIMPP as well as a license agreement that will grant the Company access to over 45 US registered patents. The Company accounted for the K/S HIMPP investment using the equity method of accounting for common stock. The investment required a payment of $260,000 to be made at the time of closing. The unpaid principal balance, which was $1,540,000 at December 31, 2006, will be paid in five annual installments of $260,000 in 2007 through 2011, with a final installment of $240,000 in 2012. The unpaid balance is unsecured and bears interest at an annual rate of 4%, which shall be payable annually with each
installment. The Company is in the process of determining the allocation of the investment in the underlying equity in net assets of K/S HIMPP, therefore the amount recorded as investment is subject to refinement.



Major Events in 2005



Sale of Burners and Components Business  In the first quarter of 2005, the Company sold the remainder of its Heat Technology segment. The total purchase price was approximately $3.5 million, subject to adjustment, of which approximately $2.7 million was paid in cash and $800,000 was paid in the form of a subordinated promissory note. This segment consisted of the operating assets and liabilities of our remaining Heat Technology Business (Dresher, Pennsylvania), Nippon Selas (Tokyo, Japan) and Selas Waermetechnik GmbH (Ratingen, Germany). This business was classified as a discontinued operation for all periods presented. For more detailed information, see note 3 to the Consolidated Financial Statements contained in the Companys 2006 annual report to shareholders, which is filed as an exhibit to this Form 10-K.

With the completed sale of the burner and components business, the Company successfully completed the shift from its traditional business segments to the emerging prospects in its precision miniature medical and electronic products business. To reflect the Companys redefined focus, it changed its name to IntriCon Corporation as of April 4, 2005.



On October 6, 2005, our subsidiary, RTI Electronics, Inc., acquired the assets of Amecon Inc. (Amecon). Amecon is primarily engaged in the research, development, manufacture, marketing and sale of toroidal power and low voltage instrument transformers, current sense transformers and filter inductors, magnetic amplifiers, AC/DC load sensors. The purchase price for the assets was $1,275,000 (after adjustment pursuant to the asset purchase agreement) and required a $10,000 initial deposit and $240,000 payment made at the time of closing. The remaining unpaid principal balance of $769,000 at December 31, 2006 will be paid in three equal annual installments with the next installment payable on October 6, 2007. The unpaid balance is unsecured and bears interest at an annual rate of 5%, which shall be payable annually with each principal payment.  The assets acquired included $228,000 of inventory,
$516,000 of fixed assets, and $663,000 of goodwill based on fair value at the date of purchase and direct and out-of-pocket acquisition costs. The goodwill is deductible for tax purposes. The Company accounted for the acquisition of Amecon using the purchase method of accounting which requires that the assets acquired and any liabilities assumed to be recorded at the date of acquisition at their respective fair values. The consolidated financial statements and results of operations reflect Amecon after the acquisition and are not restated. The cost to acquire the business was allocated to the underlying assets acquired. The acquisition expanded the microminiature business of the Company with manufacturing of toroidal power and low voltage instrument transformers, current sense transformers and filter inductor, magnetic amplifiers, AD/DC load sensors. The excess of the purchase price over identifiable assets was recorded as goodwill.

PRECISION MINIATURE MEDICAL AND ELECTRONIC PRODUCTS



Resistance Technology, Inc. (RTI),and RTI Tech PTE LTD (RTI Tech), both wholly-owned subsidiaries of the Company, manufacture microminiature components, systems and molded plastic parts for hearing instrument, medical equipment, electronics, professional audio, telecommunications and computer industry manufacturers. RTI Electronics, Inc. (RTIE), a wholly owned subsidiary of the company, has expanded RTIs microminiature components business through the manufacture of thermistors and film capacitors.



Products and Industries Serviced. RTI is a leading manufacturer and supplier of microminiature electromechanical components to hearing instrument manufacturers. These components consist of volume controls, microphones, trimmer potentiometers and switches. RTI also manufactures hybrid amplifiers and integrated circuit components (hybrid amplifiers), along with faceplates for in-the-ear and in-the-canal hearing instruments. Components are offered in a variety of sizes, colors and capacities in order to accommodate a hearing manufacturers individualized specifications.

Table of Contents

Hearing instruments, which fit behind or in a persons ear to amplify and process sound for a hearing impaired person, generally are composed of four basic parts and several supplemental components for control or fitting purposes. The four basic parts are microphones, amplifier circuits, miniature receivers/speakers and batteries. RTIs hybrid amplifiers are a type of amplifier circuit. Supplemental components include volume controls, trimmer potentiometers, which shape sound frequencies to respond to the particular nature of a persons hearing loss, and switches used to turn the instrument on and off and to go from telephone to normal speech modes. Faceplates and an ear shell, molded to fit the users ear, often serve as a housing for hearing instruments. RTI manufactures its components on a short lead-time basis in order to supply just-in-time delivery to its customers and,
consequently, order backlog amounts are not meaningful.



Using DSP technology, RTI is building a new generation of affordable, high-quality hearing aids and similar amplifier devices. Compared to most products currently on the market, DSP devices have better clarity, attractive pricing points and an improved ability to filter out background noise. Low to moderately-priced DSP hearing aids, like newly introduced line of ClariD Digital ONE DSP hearing-aid amplifiers, represent the fastest-growing segment in the hearing-aid market.



In the medical market, the Company is focused on sales of microelectronics, micromechanical assemblies and high-precision plastic molded components to medical device manufacturers. Targeted customers include medical product manufacturers of portable and lightweight battery powered devices, large AC-powered units often found in clinics and hospitals, as well as a variety of sensors designed to connect a patient to an electronic device.



The medical industry is faced with pressures to reduce the costs of healthcare. RTI offers medical manufacturers the capabilities to design, develop and manufacture components for medical devices that are easier to use, measure with greater accuracy and provide more functions while reducing the costs to manufacture these devices. Examples of RTI products used by medical device manufacturers include components found in intravenous fluid administration pumps that introduce drugs into the bloodstream. RTI manufactures and supplies bubble sensors and flow restrictors that monitor and control the flow of fluid in an intravenous infusion system.



RTI also manufactures a family of safety needle products for an OEM customer that utilizes RTIs insert and straight molding capabilities. These products are assembled using full automation including built-in quality checks within the production lines. Other examples include sensors used to detect pathologies in specific organs of the body and monitoring devices to detect cardiac and respiratory functions. The early and accurate detection of pathologies allows for increased likelihood for successful treatment of chronic diseases and cancers. Accurate monitoring of multiple functions of the body, such as heart rate and breathing, aids in generating more accurate diagnosis and treatments for patients.



RTI entered the high-quality audio communication device market in 2001, and now has a line of miniature, professional audio headset products used by performers and support staff in the music and stage performance markets. For customers focusing on homeland security needs, the line includes several communication devices that are more portable and perform well in noisy or hazardous environments. These products are also well suited for applications in the fire, law enforcement, safety, aviation and military markets.



RTIE manufactures and sells thermistors and thermistor assemblies, which are solid state devices that produce precise changes in electrical resistance as a function of any change in absolute body temperature. The balance of sales represents various industrial, commercial and military sales for thermistor and thermistor assemblies to domestic and international markets.

Table of Contents

RTIs and RTIEs principal raw materials are plastics, polymers, metals, various metal oxide powders and silver paste, for which there are multiple sources of supply.



Marketing and Competition. RTI sells its hearing instrument components directly to domestic hearing instrument manufacturers through an internal sales force. Sales of microphone products and of molded plastic parts to industries other than hearing instrument manufacturers are made mainly through an internal sales force. In recent years, five companies have accounted for a substantial portion of the sales in the United States hearing instrument industry. In 2006, no one customer accounted for more than 10 percent of the Companys consolidated net sales. During 2006, the top five customers accounted for approximately $16 million or 30 percent of the Companys consolidated net sales. See note 5 to the consolidated financial statements for a discussion of net sales and long-lived assets by geographic area.



Internationally, sales representatives employed by Resistance Technology, GmbH (RT, GmbH), a German company 90% of whose capital stock is owned by RTI, solicits sales from European hearing instrument manufacturers on behalf of RTI.



RTI believes that it is the largest supplier worldwide of micro-miniature electromechanical components to hearing instrument manufacturers and that its full product line and automated manufacturing process allow it to compete effectively with the two other manufacturers within this market.



In the market of hybrid amplifiers and molded plastic faceplates, RTIs primary competition is from the hearing instrument manufacturers themselves. The hearing instrument manufacturers produce a substantial portion of their internal needs for these components.



RTI markets its high performance microphone products to the radio communication and professional audio industries and has several larger competitors who have greater financial resources. RTI holds a small market share in the global market for microphone capsules and other related products.



RTIE sells its thermistors and film capacitors through a combination of independent sales representatives and internal sales force.



RTIE has many competitors, both domestic and foreign, that sell various thermistor and film capacitors and some of these competitors are larger and have greater financial resources. In addition, RTIE holds a relatively small market share in the world-market of thermistor and film capacitor products.



Employees. As of February 28, 2007, we had a total of 561 employees. RTI currently employs 293 people, of whom 17 are executive and administrative personnel, 9 sales, and 267 engineering and operations personnel at RTIs two facilities near Minneapolis, Minnesota.  At RT, GmbH, the Company employs 3 sales personnel located in Munich, Germany. In Singapore, RTI Tech PTE Ltd. employs 157 people, of whom 7 are administrative personnel, 2 sales, and 148 engineering and operations personnel. At its facilities in Anaheim, California, RTIE employs 108 employees, of which 6 are administrative, 5 are sales, and 97 are engineering and operations personnel. The Company considers its relations with its employees to be satisfactory. None of the Companys employees are represented by a union.



As a supplier of parts for consumer and medical products, RTI is subject to claims for personal injuries allegedly caused by its products. The Company maintains what it believes to be adequate insurance coverage.

Research and Development. RTI and RTIE conduct research and development activities primarily to improve its existing products and technology. Their research and development expenditures were $2,123,000, $1,817,000, and $1,616,000 in 2006, 2005 and 2004, respectively. See note 1 to the consolidated financial statements for information regarding customer funded research and development projects.



RTI owns a number of United States patents which cover a number of product designs and processes. The Company believes that, although these patents collectively add some value to the Company, no one patent or group of patents is of material importance to its business as a whole.



The Companys consolidated financial statements are incorporated by reference as contained in the Companys 2006 annual report to shareholders, which is filed as an exhibit to this Form 10-K.

DISCONTINUED OPERATIONS - HEAT TECHNOLOGY



The Company specialized in the controlled application of heat to achieve precise process and temperature control. The Companys principal heat technology equipment and systems were smaller standard-engineered systems, burners and combustion control equipment. The Company sold this business in the first quarter of 2005 and has accounted for it as discontinued operations in the accompanying consolidated financial statements, which are incorporated herein by reference as contained in the Companys 2006 annual report to shareholders, which is filed as an exhibit to this Form 10-K.



Standard Engineered Systems. The Company engineered and fabricated a variety of small heat treating furnaces and heat processing equipment. This standard equipment and small-furnace business was conducted principally by its then subsidiaries, Nippon Selas (Tokyo, Japan) and Selas Waermetechnik (Ratingen, Germany).



Burners and Combustion Control Equipment. At its Dresher, Pennsylvania facility and through its then subsidiaries in Japan, Nippon Selas (Tokyo) and in Germany, Selas Waermetechnik, (Ratingen), the Company designed, manufactured and sold an array of original equipment and replacement gas-fired industrial burners for many applications.



The Company was a producer of burners used in fluid processing furnaces serving the petrochemical industry. The Company also produced burners suitable for creating a high temperature furnace environment desirable in steel and glass heat treating furnaces. The Companys burners accommodated a wide variety of fuel types, environmental constraints and customer production requirements.



The Company furnished many industries with gas combustion control equipment sold both as component parts and as systems that were engineered to meet a particular customers needs. This equipment was provided with the Companys original custom-engineered and standard heat treating equipment, as replacement or additional components for existing furnaces being refurbished or upgraded, and as original components for heat treating equipment manufactured by others.



Marketing and Competition. The Company marketed its standard-engineered systems products on a global basis through its sales and marketing personnel located in Dresher, Pennsylvania, and also sold these products through licensees and agents located in various parts of the world.



Operations. The heat technology segment had a total of 48 employees. At its Dresher facility, the Company had 32 employees; 6 were executive and administrative personnel, 10 were sales and engineering personnel and 16 were personnel engaged in manufacturing. The hourly personnel were represented by a union. The Company considered its relations with its employees to be satisfactory. Selas Waermetechnik had 6 employees; 1 was an administrative personnel, 3 were sales and engineering personnel and 2 were personnel engaged in manufacturing.



In April 2001, the Company sold a minority interest of Nippon Selas to three directors of Nippon Selas. This minority interest was reacquired by the Company in the first quarter of 2005 in contemplation of the sale of this business, which was completed in the first quarter of 2005. Its Tokyo facility employed 10 people; 3 administrative and 7 sales and engineering.



Research and Development. The Company conducted limited research and development activities at its Dresher facility to support its heat processing services and products. Research and development expenditures for heat processing aggregated $4,000 and $18,000, in 2005 and 2004, respectively.

ITEM 1A.Risk Factors



You should carefully consider the risks described below. If any of the risks actually occur, our business, financial condition or results of future operations could be materially adversely affected. This Annual Report on Form 10-K contains forward-looking statements that involve risk and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of many factors, including the risks faced by us described below and elsewhere in this Annual Report on Form 10-K.



We have experienced and expect to continue to experience fluctuations in our results of operations, which could adversely affect us.



Factors that affect our results of operations include, but are not limited to, the volume and timing of orders received, changes in the global economy and financial markets, changes in the mix of products sold, market acceptance of our products and our customers products, competitive pricing pressures, global currency valuations, the availability of electronic components that we purchase from suppliers, our ability to meet increasing demand, our ability to introduce new products on a timely basis, the timing of new product announcements and introductions by our or our competitors, changing customer requirements, delays in new product qualifications, and the timing and extent of research and development expenses. These factors have caused and may continue to cause us to experience material fluctuations in operating results on a quarterly and/or annual basis. These fluctuations could materially adversely
affect our business, financial condition and results of operations, which in turn, could adversely affect the price of our common stock.



The loss of one or more of our major customers could adversely affect our results of operations.



We are dependent on a small number of customers for a large portion of our revenues. In fiscal year 2006, our five largest customers accounted for 30% of our net sales. A significant decrease in the sales to or loss of any of our major customers would have a material adverse effect on our business and results of operations. Our revenues are largely dependent upon the ability of customers to develop and sell products that incorporate our products. No assurance can be given that our major customers will not experience financial, technical or other difficulties that could adversely affect their operations and, in turn, our results of operations.



We may not be able to collect outstanding accounts receivable from our customers.



Some of our customers purchase our products on credit, which may cause a concentration of accounts receivable among some of our customers. As of December 31, 2006, we had accounts receivable, less allowance for doubtful accounts, of $8,456,450, which represented approximately 54.2 percent of our shareholders equity as of that date. As of that date, one customer accounted for approximately 10 percent of our accounts receivable. Our financial condition and profitability may be harmed if one or more of our customers are unable or unwilling to pay these accounts receivable when due.



If we are unable to continue to develop new products that are inexpensive to manufacture, our results of operations could be adversely affected.



We may not be able to continue to achieve our historical profit margins in our precision miniature medical and electronic products business due to advancements in technology. The ability to continue our profit margins is dependent upon our ability to stay competitive by developing products that are technologically advanced and inexpensive to manufacture.

Table of Contents



Our precision miniature medical and electronic products business has also been affected by unfavorable conditions in the hearing instrument market and the impact of the Asian economic situation. We are unable to predict with any certainty when and if these conditions will improve.



Our need for continued investment in research and development may increase expenses and reduce our profitability.



Our industry is characterized by the need for continued investment in research and development. If we fail to invest sufficiently in research and development, our products could become less attractive to potential customers and our business and financial condition could be materially and adversely affected. As a result of the need to maintain or increase spending levels in this area and the difficulty in reducing costs associated with research and development, our operating results could be materially harmed if our research and development efforts fail to result in new products or if revenues fall below expectations. In addition, as a result of our commitment to invest in research and development, spending levels of research and development expenses as a percentage of revenues may fluctuate in the future.



We operate in a highly competitive business and if we are unable to be competitive, our financial condition could be adversely affected.



Several of our competitors have been able to offer more standardized and less technologically advanced hearing products at lower prices. Price competition has had an adverse effect on our sales and margins. There can be no assurance that we will be able to maintain or enhance our technical capabilities or compete successfully with our existing and future competitors.



Merger and acquisition activity in our hearing health market has resulted in a smaller customer base. Reliance on fewer customers may have an adverse effect on us.



Several of our customers in the hearing health market, have undergone mergers or acquisitions, resulting in a smaller customer base with larger customers. If we are unable to maintain satisfactory relationships with the reduced customer base, it may adversely affect our operating profits and revenue.



Unfavorable legislation in the hearing health market may decrease the demand for our products, and may negatively impact our financial condition.



In some of our foreign markets, government subsidies cover a portion of the cost of hearing aids. A change in legislation that would reduce or eliminate these subsidies could decrease the demand for our hearing health products. This could result in an adverse effect on our operating results. We are unable to predict the likelihood of any such legislation.



Implementation of our growth strategy may not be successful, which could affect our ability to increase revenues.



Our growth strategy includes developing new products and entering new markets, as well as identifying and integrating acquisitions. Our ability to compete in new markets will depend upon a number of factors including, among others:




        our ability to create demand for products in new markets;



        our ability to manage growth effectively;



        our ability to successfully identify, complete and integrate acquisitions;



        our ability to respond to changes in our customers businesses by updating existing products and introducing, in a timely fashion, new products which meet the needs of our customers;



        the quality of our new products; and



        our ability to respond rapidly to technological change.

The failure to do any of the foregoing could have a material adverse effect on our business, financial condition and results of operations. In addition, we may face competition in these new markets from various companies that may have substantially greater research and development resources, marketing and financial resources, manufacturing capability and customer support organizations.



We operate in Singapore and Germany, and various factors relating to our international operations could affect our results of operations.



In 2006, we operated in Singapore and Germany. Approximately 8 percent of our revenues were derived from these countries in 2006. As of December 31, 2006 approximately 8 percent of our long lived assets are located in these countries. Political or economic instability in these countries could have an adverse impact on our results of operations due to diminished revenues in these countries. Our future revenues, costs of operations and profit results could be affected by a number of factors related to our international operations, including changes in foreign currency exchange rates, changes in economic conditions from country to country, changes in a countrys political condition, trade protection measures, licensing and other legal requirements and local tax issues. Unanticipated currency fluctuations in the Euro could lead to lower reported consolidated revenues due to the translation of these
currencies into U.S. dollars when we consolidate our revenues.



We may explore acquisitions that complement or expand our business. We may not be able to complete these transactions and these transactions, if executed, pose significant risks and may materially adversely affect our business, financial condition and operating results.



We intend to explore opportunities to buy other businesses or technologies that could complement, enhance or expand our current business or product lines or that might otherwise offer us growth opportunities. We may have difficulty finding these opportunities or, if we do identify these opportunities, we may not be able to complete the transactions for reasons including a failure to secure financing. Any transactions that we are able to identify and complete may involve a number of risks, including: the diversion of our managements attention from our existing business to integrate the operations and personnel of the acquired or combined business or joint venture; possible adverse effects on our operating results during the integration process; unanticipated liabilities; and our possible inability to achieve the intended objectives of the transaction. In addition, we may not be able to successfully or
profitably integrate, operate, maintain and manage our newly acquired operations or employees. In addition, future acquisitions may result in dilutive issuances of equity securities or the incurrence of additional debt.



We may experience difficulty in paying our debt when it comes due, which could limit our ability to obtain financing.



Our ability to pay the principal and interest on our indebtedness as it comes due will depend upon our current and future performance. Our performance is affected by general economic conditions and by financial, competitive, political, business and other factors. Many of these factors are beyond our control. We believe that our amended credit facility combined with funds expected to be generated from operations, the available borrowing capacity through our revolving credit loan facilities, curtailment of the dividend payment and control of capital spending will be sufficient to meet our anticipated cash requirements for operating needs through April 1, 2008. If, however, we are unable to renew these facilities in the future, or do not generate sufficient cash or complete such financings on a timely basis, we may be required to seek additional financing or sell equity on terms which may not be as favorable as
we could have otherwise obtained. No assurance can be given that any refinancing, additional borrowing or sale of equity will be possible when needed or that we will be able to negotiate acceptable terms. In addition, our access to capital is affected by prevailing conditions in the financial and equity capital markets, as well as our own financial condition.

Our success depends on our senior management team and if we are not able to retain them, it could have a materially adverse effect on us.



We are highly dependent upon the continued services and experience of our senior management team, including Mark S. Gorder, our President, Chief Executive Officer and a director. We depend on the services of Mr. Gorder and the other members of our senior management team to, among other things, continue the development and implementation of our business strategies and maintain and develop our client relationships.



Our future success depends in part on the continued service of our engineering and technical personnel and our ability to identify, hire and retain additional personnel.



There is intense competition for qualified personnel in our markets. We may not be able to continue to attract and retain engineers or other qualified personnel necessary for the development and growth of our business or to replace engineers or other qualified personnel who may leave our employ in the future. The failure to retain and recruit key technical personnel could cause additional expense, potentially reduce the efficiency of our operations and could harm our business.



We and/or our customers may be unable to protect our and their proprietary technology and intellectual property rights or keep up with that of competitors.



Our ability to compete effectively against other companies in our markets depends, in part, on our ability and the ability of our customers to protect our and their current and future proprietary technology under patent, copyright, trademark, trade secret and unfair competition laws. We cannot assure that our means of protecting our proprietary rights in the United States or abroad will be adequate, or that others will not develop technologies similar or superior to our technology or design around the proprietary rights we own. In addition, we may incur substantial costs in attempting to protect our proprietary rights.



Also, despite the steps taken by us to protect our proprietary rights, it may be possible for unauthorized third parties to copy or reverse-engineer aspects of our and our customers products, develop similar technology independently or otherwise obtain and use information that we or our customers regard as proprietary. We and our customers may be unable to successfully identify or prosecute unauthorized uses of our or our customers technology.



If we become subject to material intellectual property infringement claims, we could incur significant expenses and could be prevented from selling specific products.



We may become subject to material claims that we infringe the intellectual property rights of others in the future. We cannot assure that, if made, these claims will not be successful. Any claim of infringement could cause us to incur substantial costs defending against the claim even if the claim is invalid, and could distract management from other business. Any judgment against us could require substantial payment in damages and could also include an injunction or other court order that could prevent us from offering certain products.

Environmental liability and compliance obligations may affect our operations and results.

Our manufacturing operations are subject to a variety of environmental laws and regulations as well as internal programs and policies governing:


        air emissions;



        wastewater discharges;



        the storage, use, handling, disposal and remediation of hazardous substances, wastes and chemicals; and



        employee health and safety.




If violations of environmental laws should occur, we could be held liable for damages, penalties, fines and remedial actions. Our operations and results could be adversely affected by any material obligations arising from existing laws, as well as any required material modifications arising from new regulations that may be enacted in the future. We may also be held liable for past disposal of hazardous substances generated by our business or former businesses or businesses we acquire. In addition, it is possible that we may be held liable for contamination discovered at our present or former facilities.



We are subject to numerous asbestos-related lawsuits, which could adversely affect our financial position, results of operations or liquidity.



We are a defendant along with a number of other parties in approximately 122 lawsuits as of December 31, 2006, (approximately 122 lawsuits as of December 31, 2005) alleging that plaintiffs have or may have contracted asbestos-related diseases as a result of exposure to asbestos products or equipment containing asbestos sold by one or more named defendants. These lawsuits relate to the discontinued Heat Technologies segment which was sold in March 2005 and is now classified as discontinued operations. Due to the noninformative nature of the complaints, we do not know whether any of the complaints state valid claims against us. Certain insurance carriers have informed us that the primary policies for the period August 1, 1970-1973, have been exhausted and that the carriers will no longer provide a defense under those policies. We have requested that the carriers substantiate this situation. We believe we have
additional policies available for other years which have been ignored by the carriers. As settlement payments are applied to all years a litigant was deemed to have been exposed to asbestos, we believe when settlement payments are applied to these additional policies, we will have availability under the years deemed exhausted. If our insurance policies do not cover the costs and any awards for the asbestos-related lawsuits, we will have to use our cash or obtain additional financing to pay the asbestos-related obligations and settlement costs. There is no assurance that we will have the cash or be able to obtain additional financings on favorable terms to pay asbestos related obligations or settlements should they occur. The ultimate outcome of any legal matter cannot be predicted with certainty. In light of the significant uncertainty associated with asbestos lawsuits, there is no guarantee that these lawsuits will not materially adversely affect our financial position, results of
operations or liquidity.



The market price of our common stock has been and is likely to continue to be volatile, which may make it difficult for shareholders to resell common stock when they want to and at prices they find attractive.



The market price of our common stock has been and is likely to be highly volatile, and there has been limited trading volume in the common stock. The common stock market price could be subject to wide fluctuations in response to a variety of factors, including the following:




        announcements of fluctuations in our or our competitors operating results;



        the timing and announcement of sales or acquisitions of assets by us or our competitors;



        changes in estimates or recommendations by securities analysts;



        adverse or unfavorable publicity about our services or us;



        the commencement of material litigation, or an unfavorable verdict, against us;



        terrorist attacks, war and threats of attacks and war;



        additions or departures of key personnel; and



        sales of common stock.

In addition, the stock market in recent years has experienced significant price and volume fluctuations. Such volatility and decline has affected many companies irrespective of, or disproportionately to, the operating performance of these companies. These broad fluctuations and limited trading volume may materially adversely affect the market price of the common stock, and the ability to sell said common stock.



Most of our outstanding shares are available for resale in the public market without restriction. The sale of a large number of these shares could adversely affect the share price and could impair our ability to raise capital through the sale of equity securities or make acquisitions for common stock.



Terrorist attacks, war and threats of attacks and war may negatively impact our results of operations, revenue and common stock market price.



Terrorist attacks, war and threats of attacks and war may negatively impact our results of operations, revenue and share price. Recent terrorist attacks in the United States, as well as future events occurring in response or in connection to them, including, without limitation, future terrorist attacks against United States targets and threats of war or actual conflicts involving the United States or its allies, may impact our operations, including affecting our ability to operate our subsidiaries abroad. More generally, any of these events could cause consumer confidence and spending to decrease or result in increased volatility in the economy. They could also result in the deepening of the economic recession in the United States. Any of these occurrences could have a material adverse effect on our operating results, revenue, and may result in the volatility of the market price for our common stock.



Anti-takeover provisions may make it more difficult for a third party to acquire control of us, even if the change in control would be beneficial to shareholders.



We are a Pennsylvania corporation. Anti-takeover provisions in Pennsylvania law and our charter and bylaws could make it more difficult for a third party to acquire control of us. These provisions could adversely affect the market price of the common stock and could reduce the amount that shareholders might receive if we are sold. For example, our charter provides that the board of directors may issue preferred stock without shareholder approval. In addition, our bylaws provide for a classified board, with each board member serving a staggered three-year term. Directors may be removed only with the approval of the holders of at least two-thirds of all of the shares outstanding and entitled to vote.



If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud. As a result, current and potential shareholders and customers could lose confidence in our financial reporting, which could harm our business, the trading price of our stock and our ability to retain our current customers or obtain new customers.



Beginning in fiscal 2004, we began a process to document and evaluate our internal controls over financial reporting in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal controls over financial reporting and a report by our independent auditors addressing these assessments. In this regard, management has been dedicating internal resources, has engaged outside consultants and has adopted a detailed work plan to (i) assess and document the adequacy of internal controls over financial reporting, (ii) take steps to improve control processes, where

appropriate, (iii) validate through testing that controls are functioning as documented and (iv) implement a continuous reporting and improvement process for internal control over financial reporting. At this time, we are not aware, and our outside auditors have not advised us, of any material weaknesses or significant deficiencies in our internal controls, as defined in the relevant literature. If we fail to identify and correct any issues in the design or operating effectiveness of internal controls over financial reporting or fail to prevent fraud, current and potential shareholders and customers could lose confidence in our financial reporting, which could harm our business, the trading price of our stock and our ability to retain our current customers and obtain new customers.

ITEM 3.
        Legal Proceedings




The Company is a defendant along with a number of other parties in approximately 122 lawsuits as of December 31, 2006, (approximately 122 lawsuits as of December 31, 2005) alleging that plaintiffs have or may have contracted asbestos-related diseases as a result of exposure to asbestos products or equipment containing asbestos sold by one or more named defendants. These lawsuits relate to the discontinued Heat Technologies segment which was sold in March 2005 and is now classified as discontinued operations. Due to the noninformative nature of the complaints, the Company does not know whether any of the complaints state valid claims against the Company.

The Company has requested that the carriers
substantiate this situation. The Company believes it has additional policies available for other years which have been ignored by the carriers. As settlement payments are applied to all

Table of Contents

years a litigant was deemed to have  been exposed to asbestos, the Company believes when settlement payments are applied to these additional policies, the Company will have availability under the years deemed exhausted. The Company does not believe that the asserted exhaustion of the primary insurance coverage for this period will have a material adverse effect on its financial condition, liquidity, or results of operations. Management believes that the number of insurance carriers involved in the defense of the suits and the significant number of policy years and policy limits, to which these insurance carriers are insuring the Company, make the ultimate disposition of these lawsuits not material to the Companys consolidated financial position or results of operations.



A claim has been made against the Company by BET Investments (BET) for recovery of costs allegedly incurred by BET in connection with the removal of drums containing hazardous materials and related clean-up costs from real estate which the Company sold to BET in 2003 and upon which the Company formerly operated a manufacturing facility. Based upon invoices submitted by BET, the maximum amount of BETs claim is approximately $270,000. The Company and its counsel are currently evaluating the extent of the Companys liability, if any, for this claim. Although we are unable to estimate the exact amount of loss, we believe at this time the loss estimate could range from $0 to $270,000. Based on the information available to us at this time, no amount in this range appears to be a better estimate than any other amount. As such, as of December 31, 2006 we have not recorded a reserve for this claim.



The Companys former wholly owned French subsidiary, Selas SAS, filed for insolvency in France and is being managed by a court appointed judiciary administrator. The Company may be subject to additional litigation or liabilities as a result of the French insolvency proceeding.



The Company is a defendant, along with a number of other parties, in a lawsuit made by Energy Transportation Group, Inc. (ETG) alleging infringement of certain patents. Based upon the discovery provided thus far by the Plaintiff, the Company and its counsel believe the Company has meritorious defenses to this matter. As such, as of December 31, 2006 we have not recorded a reserve for this claim.



The Company is also involved in other lawsuits arising in the normal course of business. While it is not possible to predict with certainty the outcome of these matters, management is of the opinion that the disposition of these lawsuits and claims will not materially affect the Companys consolidated financial position, liquidity, or results of operations.

The closing sale price of the Companys common shares on March 9, 2007, was $5.95 per share.



At March 9, 2007 the Company had 355 shareholders of record of common shares. Such number of records does not reflect shareholders who beneficially own common stock in nominee or street name.



The Company ceased paying quarterly cash dividends in the fourth quarter of 2001 and has no intention of paying cash dividends in the foreseeable future. The payment of any future cash dividends is subject to the discretion of the Board of Directors and is dependent on a number of factors, including the Companys capital requirements, financial condition, financial covenants and cash availability. Terms of the Companys banking agreements prohibit the payment of cash dividends without prior bank approval.

ITEM 9.
        Changes in and Disagreements With Accountants on Accounting and Financial Disclosure




On August 23, 2005, the Corporation dismissed KPMG LLP (KPMG) as its independent registered public accountants. The Corporations Audit Committee made and approved the decision to change the independent registered public accountants. The report of KPMG on the Corporations financial statements for the years ended December 31, 2004 and 2003 contained no adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principle except that the report for the years ended December 31, 2004 and 2003 included a separate paragraph which indicated that the Corporation restated its consolidated financial statements as of and for the years ended December 31, 2004 and 2003.  In connection with its audits for the years ended December 31, 2004 and 2003 and through August 23, 2005, there have been no disagreements with KPMG on any matter of
accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG, would have caused them to make reference thereto in their report on the financial statements for such years.



Effective as of August 23, 2005, the Corporation engaged Virchow, Krause & Company, LLP as its new independent registered public accountants. The decision to engage Virchow, Krause & Company, LLP was made and approved by the Audit Committee of the Board of Directors. During the years ended December 31, 2004 and 2003 and through August 23, 2005, the Corporation did not consult with Virchow, Krause & Company, LLP regarding (A) either: the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Corporations financial statements; or (ii) any matter that was either subject of a disagreement, as that term is defined in Item 304 (a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K, or a reportable event, as that term is described in Item 304(a)(1)(v) of Regulation S-K.



ITEM 9A.
        Controls and Procedures




The Companys management, with the participation of its chief executive officer and chief financial officer, conducted an evaluation of the effectiveness of the Companys disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e), as of December 31, 2006 (the Disclosure Controls Evaluation). Based on the Disclosure Controls Evaluation, the Companys chief executive officer and chief financial officer concluded that the Companys disclosure controls and procedures were effective to provide a reasonable level of assurance that: (i) information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the specific time periods in the Securities and Exchange Commissions rules and forms and (ii)  information required to be disclosed in the reports the
Company files or submits under Exchange Act are accumulated and communicated to management, including the chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure, all in accordance with Exchange Act Rule 13a-15(e).

There were no changes in the Companys internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f), during the quarter ended December 31, 2006, that have materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.



A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.



ITEM 9B.
        Other Information




In the fourth quarter of 2006, the Company joined the Hearing Instrument Manufacturers Patent Partnership (HIMPP). Members of the partnership include the largest six hearing aid manufacturers as well as several other smaller manufacturers.  The purchase price of $1,800,000 includes an equity interest in K/S HIMPP as well as a license agreement that will grant the Company access to over 45 US registered patents. The Company accounted for the K/S HIMPP investment using the equity method of accounting for common stock. The investment required a payment of $260,000 to be made at the time of closing. The unpaid principal balance which was $1,540,000 at December 31, 2006, will be paid in five annual installments of $260,000 in 2007 through 2011, with a final installment of $240,000 in 2012. The unpaid balance is unsecured and bears interest at an annual rate of 4%, which shall be payable annually with each
installment. The Company is in the process of determining the allocation of the investment in the underlying equity in net assets of K/S HIMPP, therefore the amount recorded as investment is subject to refinement.



A copy of the HIMPP Agreement and the schedules thereto are attached as Exhibit 10.32 and are incorporated herein by reference.
