BUSINESS

Overview

We are in the business of developing and marketing consumer health care products, including Breathe Right® branded products focused on better breathing, and FiberChoice® branded products focused on digestive health. We operate in niche categories of the large over-the-counter health care market with unique product offerings that are supported by strong advertising and promotion programs. Our competitive strengths include our brands, patented technologies, well-established distribution networks domestically and internationally, a flexible and low-cost operating model and an experienced management team.

Our principal product, the Breathe Right® nasal strip, improves breathing by dilating the nasal passages. Nasal strips provide temporary relief from nasal congestion and stuffiness resulting from a variety of health conditions, and also reduce or eliminate snoring. Breathe Right nasal strips provide consumers a “drug free” better breathing solution.

The Breathe Right brand has been extended by the launch of products such as Breathe Right® Snore Relief™ throat spray in fiscal 2003 and Breathe Right® Snore Relief™ throat rinse scheduled for launch in July 2006. Both products provide drug free, over the counter solutions to manage snoring. Clinical studies have shown that 85% of people with common snoring problems experience a reduction or elimination of their symptoms by using these products in combination with Breathe Right nasal strips.

Breathe Right® Vapor Shot!™ personal vaporizer and Breathe Right® saline nasal spray are being phased out during fiscal 2007 as a result of low sales volume.

We entered the bulk fiber category in March 2000 with the launch of the FiberChoice brand. The original FiberChoice product is an orange flavored chewable fiber tablet that offers consumers an effective, convenient and good-tasting way to supplement their daily intake of dietary fiber. In March 2005, CNS extended the FiberChoice line to include sugar-free chewable fiber tablets in assorted fruit flavors and a low-sugar, hard candy fiber drop. The hard candy fiber drop product is being phased out during fiscal 2007 as the result of lower than anticipated consumer demand.

The FiberChoice brand was further extended in fiscal 2006 with the launch of FiberChoice® plus Calcium and FiberChoice® Weight Management chewable tablets. Both products provide the benefits of the original fiber tablets while delivering the added benefits of calcium or weight management ingredients in the same convenient chewable form.

In addition, we are exploring opportunities to acquire established consumer health care brands, product lines and new technologies that complement our better breathing and digestive health brand platforms.

History

CNS was founded in 1982. From 1982 until 1995, the Company designed, manufactured and marketed computer-based diagnostic devices for sleep disorders. In 1992, CNS obtained the exclusive license to manufacture and sell nasal strips, and in 1993 received FDA clearance to market the nasal strip as a product that improves nasal breathing. In 1994, CNS launched the Breathe Right nasal strip in the United States and in 1995 divested itself of the assets related to its sleep disorders business in order to focus on further developing the Breathe Right nasal strip product. In 1998, CNS strengthened its management team to add consumer healthcare products experience, and since that time continued to develop the Breathe Right brand both domestically and internationally. In 2000, CNS added its second branded product line with the

launch of FiberChoice chewable fiber tablets. In fiscal 2006, we purchased the patents and patents pending relating to the FiberChoice chewable fiber products.

Competitive Strengths

•

Development of Strong Brands within Attractive Niche Categories. Our core competency is sales and marketing of consumer healthcare products. We have strategically chosen to focus on niche product categories with unique and high margin product offerings that address recurring consumer needs, and support these products with ongoing advertising and promotion campaigns. Our goal is to develop strong consumer demand based on brand awareness and product loyalty, allowing us to achieve long term growth in sales and profitability.

•

Proven Ability to Develop Technologies and Products. We focus our product development efforts on identifying underserved consumer needs and then designing products that directly address those unmet needs. The Breathe Right nasal strip and the FiberChoice chewable fiber tablet were both developed by licensing or acquiring the patented technologies from inventors and creating new consumer brands. Both Breathe Right and FiberChoice brands have been expanded through new product launches.

•

Efficient Operating Model. We focus our internal resources on marketing, sales and product development. We directly manage the production planning and quality control aspects of manufacturing, but outsource manufacturing to well-established, low-cost third-party suppliers. This approach allows us to benefit from manufacturing expertise and economies of scale, and maintain a highly flexible and variable cost structure, with low overhead and low capital investment. We internally manage all aspects of customer service and distribution of our products, delivering a high standard of service to our customers.

•

Experienced Management Team. We have an experienced management team, with a proven track record of developing branded consumer healthcare products and building shareholder value. Although we maintain a lean staff of approximately 65 full-time equivalent employees, we believe we have the skill and experience of larger companies in our industry. We organize our management structure into five strategic teams focused on growth: Breathe Right brand teams, for domestic and international markets, the FiberChoice brand team and new product development teams for both the Breathe Right and FiberChoice brands.

Growth Strategies

Investing in Advertising and Promotion.

Breathe Right Brand. Our marketing efforts for Breathe Right products are targeted against two key consumer healthcare conditions: nasal congestion and snoring. The majority of advertising and promotion investment is spent on television advertising, which communicates the unique Breathe Right brand benefits of instant, drug-free relief from nasal congestion and snoring. We also use other promotion programs, such as sampling, coupons, in-store advertising and public relations activities. Marketing communications promote trial, as well as repeat purchases of Breathe Right brand products by increasing consumer awareness and developing product loyalty.

FiberChoice Brand. Our marketing efforts for FiberChoice products are targeted toward the growing awareness of the need for increased consumption of dietary fiber, and the important health benefits associated with consuming higher levels of dietary fiber. In addition to communicating the importance of increased consumption of dietary fiber, recent new product launches are focused on the growing demand for additional dietary supplements including calcium and weight management ingredients. The majority of advertising and promotion investment is spent on television advertising, which

Table of Contents

communicates the challenge that active people face in meeting the recommended daily fiber consumption and other dietary needs.

The advertising message also highlights the unique benefits offered by FiberChoice products including convenience, efficacy and good taste. Marketing communications are focused on building awareness, which is still at an early stage, and developing strong brand loyalty.

Developing New Products. The Breathe Right and FiberChoice brand names are two of our most valuable assets and we intend to continue leveraging these assets by future introduction of new products. Our goal is to continue to develop a pipeline of potential new products under both the Breathe Right and FiberChoice brands, linked to their respective brand equities of better breathing and digestive health.

Developing Domestic Distribution. Breathe Right and FiberChoice products are sold to mass merchandise stores, drug stores, grocery stores, warehouse clubs, military base stores and on-line retailers in the United States. We sell our products through a dedicated direct sales force that concentrates on serving key retail accounts as well as through national brokerage organizations which serve our smaller customers.

Our customers generally merchandise our products in the over-the-counter drug section of their stores. Breathe Right nasal strips are typically positioned in the cough, cold and allergy sections of stores because they provide benefits similar to those obtained from other decongestant products. FiberChoice products are positioned in the bulk fiber laxative sections of stores.

Our retail customers include national chains of mass merchants, drug stores and grocery stores such as Wal-Mart, Target, Eckerd, Walgreen’s, RiteAid, CVS, Kroger and Albertson’s and warehouse clubs such as Sam’s Club and Costco, as well as regional and independent stores in these retail channels. In fiscal 2006, Wal-Mart Corporation accounted for approximately 31% of sales.

Expanding Company Presence in International Markets. The Company believes that there is significant market potential for its products outside the United States and is actively developing the Breathe Right brand in selected international markets, most importantly Japan, Europe and Canada. We have established a broad-ranging international distribution system for Breathe Right nasal strips that consists of distributors, sales representatives and suppliers that repackage bulk nasal strips into final consumer packaging. Distributors are appointed largely on an exclusive basis, with territories consisting of one or more countries, and it is expected that this pattern of operation will continue. We retain control over the brand, packaging and advertising in all international markets.

Development of a Third Brand Platform. We are exploring opportunities to acquire or develop a third branded consumer healthcare platform or acquire complementary products which would fit under the Breathe Right or FiberChoice brands. We expect that a potential acquisition would expand our product line within consumer healthcare product categories, leveraging our core competency in sales and marketing, as well as increasing efficiency of our distribution system. There can be no assurances that such an opportunity will be realized.

Products & Markets

Breathe Right Nasal Strips. The Breathe Right nasal strip is a non-prescription, single-use disposable device that improves breathing by dilating the nasal passages. The Company has 510(k) clearance from the United States Food and Drug Administration (“FDA”) to market the Breathe Right nasal strip for improvement of nasal breathing, temporary relief of nasal congestion, elimination or reduction of snoring and temporary relief of breathing difficulties due to a deviated nasal septum. See Item 1, “Government Regulation.”

Table of Contents

The Breathe Right nasal strip includes two embedded flexible “spring-like” pieces which gently lift nasal passages open while a special adhesive holds the strip comfortably in place. The product improves nasal breathing during use and is drug-free, thereby avoiding the side effects associated with many competing products. The Breathe Right nasal strip is offered in two sizes (small/medium and large), and three varieties (tan, clear, and mentholated). Mentholated nasal strips contain a soothing mentholated aroma for additional relief from nasal congestion. Clear nasal strips have been positioned as an alternative for consumers who wish to use the product frequently, but suffer from dry or sensitive skin.

Other Breathe Right Products. Breathe Right Snore Relief throat spray and Breathe Right Snore Relief Throat Rinse are drug-free products that address the snoring condition in a complimentary way relative to nasal strips. Clinical studies have shown that 85 percent of people with common snoring problems experience a reduction or elimination of their symptoms by using one of these products in combination with Breathe Right nasal strips.

Breathe Right Markets & Competition. Our marketing efforts capitalize on the multiple benefits of Breathe Right products, providing solutions to consumers within the following market segments:

• Nasal Congestion Market. Annually most Americans suffer from nasal congestion as a result of the common cold, while nasal congestion as a result of allergies affects approximately 35 million Americans. We believe that Breathe Right nasal strips are often used as either an alternative or as an adjunct to decongestant drugs (including nasal sprays and oral decongestants). This broad cold/flu/allergy market represents significant potential for the Breathe Right brand.

• Snoring Market. Snoring is a large potential market given estimates that approximately 37 million Americans snore regularly, while another 50 million Americans snore occasionally. We believe that the percentage of international consumers that suffer from snoring is broadly equivalent to the United States. Based on results from clinical trials, Breathe Right products were effective in reducing or eliminating snoring for approximately 85 percent of participants.

• Improved Breathing for Consumers with Deviated Septa. Approximately 12 million people in the United States suffer from a deviated septum, a bend in the cartilage or bone that divides the nostrils. Breathe Right nasal strips were cleared by the Food and Drug Administration in 1996 to provide temporary relief from breathing difficulties associated with a deviated septum.

• Athletic Market. We believe that Breathe Right nasal strips make nasal breathing more comfortable and may improve endurance during athletic activity, particularly when a mouth guard is used. An exercise physiology study published in peer-reviewed medical literature in 1997 concluded that Breathe Right nasal strips provided physiologic advantages in ventilation and heart rate during mid-level exercise.

Competition in Breathe Right Markets. The market for decongestant products is highly competitive, and many of the competitors have significantly greater financial and operating resources than CNS. Our competition in the consumer market for decongestant products and other cold, allergy and sinus relief products consists primarily of pharmaceutical products sold over the counter, nasal sprays and other external nasal dilators. Competition in the snoring remedies market consists primarily of nasal dilators, throat sprays and herbal products, including supplements and homeopathic remedies.

Table of Contents

Although we have historically achieved approximately 90% to 95% share of the external nasal dilator market, Schering Plough Corp. entered the market in September 1998 with an external nasal dilation device. In May 2003, Aso Corporation acquired the brand, including the sales and distribution of Schering Plough’s nasal strip device. Other companies have also entered the nasal dilation market with private label products.

We believe the patents owned and licensed by the Company on the Breathe Right nasal strip will limit the ability of others to introduce competitive external nasal dilator products similar to the Breathe Right nasal strip in the United States and most major international markets. We intend to aggressively enforce our patent rights covering the Breathe Right nasal strip and have engaged in litigation to protect its patent rights. However, there can be no assurance that potential competitors will not be able to develop nasal dilation products which circumvent our patents.

FiberChoice Daily Fiber Supplement. FiberChoice is a line of daily fiber supplements that offer consumers an effective, convenient, good-tasting way to supplement their daily intake of dietary fiber. Two FiberChoice chewable tablets contain four grams of fiber and provide more than twice the amount of fiber per dose compared to other convenient fiber supplements. The active ingredient in FiberChoice tablets is inulin, a natural fiber source, which is a prebiotic that helps promote the growth of healthy bacteria in the intestinal tract. FiberChoice products can be taken without water and have been clinically proven to be as effective as powder alternatives. In addition to providing consumers with a convenient source of dietary fiber, the FiberChoice product line has been expanded to meet consumer demand for a fiber supplement fortified with calcium or weight management ingredients.

Approximately 10 million U.S. households annually purchase bulk fiber products, primarily to promote regularity and improve digestive health. The bulk fiber category represents approximately $340 million in U.S. retail sales. We believe this is an attractive product category due to the aging of the U.S. population.

Competition in FiberChoice Markets. The market for dietary fiber supplements is highly competitive and dominated by large companies with better established brands and greater resources than CNS. Competitors include Metamucil® manufactured by Procter and Gamble, Citrucel® manufactured by GlaxoSmithKline, Benefiber® manufactured by Norvartis and FiberCon® manufactured by Wyeth. The technology of the FiberChoice chewable fiber tablet is currently protected by one owned U.S. patent with other U.S. and international patents pending.

Manufacturing and Operations

We outsource all manufacturing to outside suppliers. Each supplier manufactures a portion of our product line to our detailed specifications using raw materials specified by CNS. All suppliers have entered into confidentiality agreements with CNS to protect our intellectual property rights. Our quality control and operations personnel regularly inspect these manufacturers to observe processes and procedures to ensure compliance with FDA Good Manufacturing Practice Standards. Finished goods are also inspected to ensure that they meet quality requirements. We work closely with raw material vendors and our manufacturers to reduce scrap and waste, improve efficiency and improve yields to reduce the manufacturing costs of the product. We have received certification that CNS has established and maintains a quality system which meets the requirements of ISO 9001:2000/EN 46001.

All of our manufacturing supply agreements are documented by contracts, with terms ranging from 2 to 5 years. Prices under these agreements are generally established annually and subject to periodic adjustments for changes in actual raw material costs. All of our products are ordered on a purchase order basis and result in no long-term obligations or commitments.

Table of Contents

To ensure consistent quality and supply, we have multi-year contracts with the suppliers that provide most of the major components for nasal strips. During fiscal 2005, we entered into a multi-year contract with 3M that provides for consistent supply, adherence to specifications and pricing for raw materials used in the manufacturing of nasal strips. Although similar materials are currently available from other suppliers, we have historically utilized 3M components for manufacturing nasal strips. Although we believe that this relationship will not be disrupted, the inability to obtain sufficient quantities of these components or the need to develop alternative sources in a timely and cost-effective manner could adversely affect our operations until new sources of these components become available.

We consolidate all domestic finished goods inventories into our leased warehouse adjacent to our offices in Eden Prairie, MN. We retain control of all aspects of customer service, including arranging logistics for shipment of our product to domestic customers and international distributors.

Government Regulation

As a manufacturer and marketer of medical devices, we are subject to regulation by governmental entities including the FDA and the corresponding agencies of the states and foreign countries in which we sell our products. We must comply with a variety of regulations, including the FDA’s Good Manufacturing Practice regulations, and we are subject to periodic inspections by the FDA and applicable state and foreign agencies. If the FDA believes that its regulations have not been fulfilled, it may implement extensive enforcement powers, including the ability to ban products from the market, prohibit the operation of manufacturing facilities and effect recalls of products from customer locations. We believe that CNS is currently in compliance with applicable FDA regulations.

FDA regulations classify medical devices into three categories that determine the degree of regulatory control to which the manufacturer of the device is subject. In general, Class I devices involve compliance with labeling and record keeping requirements and are subject to other general controls. Class II devices are subject to performance standards in addition to general controls. Class III devices are those devices, usually invasive, for which pre-market approval (as distinct from pre-market notification) is required before commercial marketing to assure product safety and effectiveness. Nasal dilators, such as our Breathe Right nasal strips, have been classified by the FDA as Class I devices.

Before a new medical device can be introduced into the market, the manufacturer generally must obtain FDA clearance through either a 510(k) pre-market notification or a pre-market approval application (“PMA”). A 510(k) clearance will be granted if the submitted data establish that the proposed device is “substantially equivalent” to a legally marketed Class I or II medical device, or to a Class III medical device for which the FDA has not called for PMAs. The PMA process can be expensive, uncertain and lengthy, frequently requiring from one to several years from the date the PMA is accepted. In addition to requiring clearance for new products, FDA rules may require a filing and waiting period prior to marketing modifications of existing products. We have received 510(k) pre-market notification approvals to market the Breathe Right nasal strip as a device that can (i) temporarily relieve the symptoms of nasal congestion and stuffy nose, (ii) eliminate or reduce snoring, (iii) improve nasal breathing by reducing nasal airflow resistance, and (iv) temporarily relieve breathing difficulties due to a deviated nasal septum.

Our FiberChoice product is considered to be a dietary supplement and is regulated under the Federal Food, Drug, and Cosmetic Act as amended by the Dietary Supplement Health and Education Act “DSHEA” of 1994, and under the Fair Packaging and Labeling Act. There is generally no requirement that a company obtain a license or approval from FDA before marketing dietary supplements in the United States. The FDA is currently developing regulations for certain provisions of the DSHEA that may affect the regulation of our FiberChoice product line. However, at this time, the impact of any proposed regulation on our product lines is not certain.

Table of Contents

Sales of our products outside the United States are subject to regulatory requirements that vary widely from country to country. We have selected a third party to act as an “Authorized Representative” in the European Union. We believe that we have the necessary documentation to support affixing the “CE” mark, an international symbol of quality and compliance with applicable European medical device directives, to our Breathe Right® nasal strips in Europe. We will pursue additional approvals in other jurisdictions as needed.

No assurance can be given that the FDA or state or foreign regulatory agencies will give approvals or clearances for additional applications for the Breathe Right nasal strip or for any of our other products. Moreover, after clearance is given, we are required to advise the FDA and other regulatory agencies of modifications to our products. These agencies have the power to withdraw the clearance or require us to change the device or its manufacturing process or labeling, to supply additional proof of its safety and effectiveness or to recall, repair, replace or refund the cost of the medical device if it is shown to be hazardous or defective. The process of obtaining clearance to market products is costly and time-consuming and can delay the marketing and sale of our products. Furthermore, federal, state and foreign regulations regarding the manufacture and sale of medical devices and other products are subject to future change. We cannot predict what impact, if any, such changes might have on our business.

We are also subject to substantial federal, state and local regulation regarding occupational health and safety, environmental protection, hazardous substance control, waste management and disposal, among others.

Patents, Trademarks and Proprietary Rights

We have registered trademarks, own several patents and pending patent applications, and have a number of patents through licenses which are used in connection with our business. Some of these patents and licenses cover significant product formulations, methods and designs for our current and possible future products. We believe our trademarks are important as protection for CNS’ image in the marketplace. Our success is and will continue to be dependent upon the existence of and ability to protect our trademarks, patents and licensed patents and we intend to take such steps as are necessary to protect our intellectual property rights.

There can be no assurance that our technology and proprietary rights will not be challenged on the grounds that our products infringe on patents, copyrights or other proprietary information owned or claimed by others, or that others will not successfully utilize part or all of our technology without compensation to CNS. Nor can there be any assurance that others will not attempt to challenge the validity or enforceability of our patents and licensed patents on the basis of prior art or introduce competitive products. In addition to seeking patent protection for its products, we also intend to protect our proprietary technologies and proprietary information as trade secrets.

Through license agreements CNS has acquired the exclusive worldwide rights to manufacture and sell nasal strips. Specifically, we have the exclusive right pursuant to those license agreements to manufacture, sell and otherwise practice any invention claimed in the licensors’ patents issued in any country, including those that issue on pending applications. We are obligated to pay royalties to the licensors based on sales of the products typically including certain minimum royalty amounts in order to maintain our exclusive rights.

The original licensor of nasal strip technology has filed patent applications with the U.S. Patent and Trademark Office seeking patent protection for different aspects of the nasal strip technology. Seven of these patent applications have resulted in issued patents in the United States, including one with claims that cover the single-body construction of the nasal strip. The licensor of nasal strip technology also has one patent application which is currently pending. In addition, that licensor has obtained patent protection on the nasal strip in several foreign countries and has various applications pending which seek further patent

Table of Contents

protection in these and a number of additional countries. The licensor of the mentholated vapor strip technology has filed several patent applications with the U.S. Patent and Trademark Office as well as international patent offices resulting in both issued and pending applications. In addition to the patents and patent applications pending in the U.S. mentioned above, we have filed corresponding patent applications seeking protection in several foreign countries to protect our intellectual property rights related to the nasal strip.

We have one owned U.S. patent and other U.S. and international patents pending seeking patent protection for various aspects of the chewable fiber product.

Although we believe that our owned and licensed patents will limit the ability of others to introduce competitive products in the United States, there can be no assurance that the patents on the nasal strip and the chewable fiber tablet will effectively prevent the development of competitive products or that we will have sufficient resources to pursue enforcement of any patents issued. We do, however, intend to aggressively enforce our patents. In order to enforce any patents issued, we may have to engage in litigation which may result in substantial expense and counterclaims against CNS. Any adverse outcome of such litigation could have a negative impact on our business.

We have engaged in litigation to enforce our patent rights relating to the Breathe Right nasal strip. In 1999, CNS brought a suit in federal district court to enforce one of the licensed nasal strip patents containing the broadest claims and providing the most comprehensive protection. In the course of this suit, the defendant requested reexamination in the U.S. Patent and Trademark Office (the “Patent Office”) of our primary licensed patent. On September 29, 2000, the Patent Office issued an Office Action in Reexamination and rejected certain of the claims. Other claims that were not subject to reexamination remain in effect. We have joined the licensor, Creative Integration & Design, Inc., in the exercise of our rights to contest the action of the Patent Office and have provided reasons that we believe establish that the claims should not have been rejected. CNS and its licensor are also seeking to amend certain claims to provide us with additional protection under the patent. The final outcome of the reexamination by the Patent Office is therefore uncertain. Although an adverse ruling from the Patent Office would narrow the protection available for nasal dilators and limit the breadth of the our patent protection, we believe that our current portfolio of both pending patent applications and newly issued patents will enable CNS to maintain significant patent protection for our nasal strip products.

On February 18, 2004, CNS, together with Creative Integration & Design, Inc., sued Silver Eagle Labs, Inc. in the United States District Court for the District of Minnesota for infringement of two nasal dilator patents owned by Creative Integration & Design, Inc. and exclusively licensed to the Company. On April 13, 2006, CNS, together with Creative Integration & Design, Inc. sued JMS Labs Limited, LLC in the United States District Court for the District of Minnesota for infringement of one nasal dilator patent owned by Creative Integration & Design, Inc. and exclusively licensed to the Company. See “Item 3. Legal Proceedings.”

CNS has registered its Breathe Right and FiberChoice trademarks in the United States and in several foreign countries and is seeking further registration of those trademarks and other trademarks.

Employees

At April 28, 2006, we had 58 full-time employees and 12 part-time employees, of whom 17 were engaged in operations, 23 in general administration, and 30 in marketing and sales. There are no unions representing CNS’ employees. Relations with its employees are believed to be positive and there are no pending or threatened labor employment disputes or work interruptions.

RISK FACTORS

Forward-Looking Statements

We make written and oral statements from time to time regarding our business and prospects, such as projections of future performance, statements of management’s plans and objectives, forecasts of market trends, and other matters that are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Statements containing the words or phrases “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimates,” “projects,” “believes,” “expects,” “anticipates,” “intends,” “target,” “goal,” “plans,” “objective,” “should” or similar expressions identify forward-looking statements, which may appear in documents, reports, filings with the Securities and Exchange Commission, news releases, and written or oral presentations made by our authorized officers or other representatives. For such statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Table of Contents

Our future results, including results related to forward-looking statements, involve a number of risks and uncertainties. No assurance can be given that the results reflected in any forward-looking statements will be achieved. Any forward-looking statement made by or on behalf of us speaks only as of the date on which such statement is made. We do not undertake any obligation to update or keep current either (i) any forward-looking statement to reflect events or circumstances arising after the date of such statement, or (ii) the important factors that could cause our future results to differ materially from historical results or trends, results anticipated or planned by us, or which are reflected from time to time in any forward-looking statement which may be made by or on behalf of us.

In addition to other matters identified or described by us from time to time in filings with the Securities and Exchange Commission, there are several important factors that could cause our future results to differ materially from historical results that are reflected from time to time in any forward-looking statement that may be made by or on behalf of us. Some of these important factors include the following:

We depend upon sales of our Breathe Right nasal strip for the majority of our revenues.

Sales from our Breathe Right nasal strips accounted for 76.4%, 79.7% and 77.0% of our revenues during the fiscal years ended March 31, 2006, 2005 and 2004, respectively. As a result, our success is substantially dependent upon the success of our Breathe Right nasal strip products. If we are unable to successfully create sustained demand for our Breathe Right nasal strip products and introduce new Breathe Right nasal strip products to generate additional sales, our business, financial condition and results of operations will be materially and adversely affected. Effective marketing and

advertising drive sales of Breathe Right nasal strips and therefore, our success will also depend significantly on our ability to effectively market our Breathe Right nasal strips to consumers. Further, higher than expected manufacturing, marketing and distribution costs, mild cold and flu seasons, lower than expected customer acceptance of new products and competitive forces may require us to alter our pricing or marketing structure in a manner that could have a material and adverse effect on us or otherwise adversely affect our sales of Breathe Right nasal strip products.

Our business is subject to seasonality that may cause our quarterly operating results to fluctuate materially and cause the market price of our common stock to decline.

Sales of our Breathe Right products are seasonal in nature with consumer demand generally higher during the cold and flu season and dependent upon the severity of the cold/flu season. The cold and flu season corresponds with the third and four quarters of each of our fiscal years. Therefore, we will typically experience periods of increased revenues during the third and fourth quarter. Additionally, because consumer demand for our Breathe Right nasal strip is tied to the severity of the cold/flu season, our revenues from sales of our Breathe Right products will be adversely affected by a mild cold/flu season. However, because the length and severity of the season is difficult to anticipate, we cannot estimate the fluctuation of our sales from quarter to quarter in a fiscal year or the impact of the cold/flu season year to year. If our operating results are below financial analysts’ or investors’ expectations due to seasonality factors, the market price of our common stock may decline.

Our future growth will depend in part upon our ability to develop and achieve sales of new products.

One element of our growth strategy is focused on successful development of new products, including new products under the Breathe Right and FiberChoice brand names. We may develop new products internally or through acquisition of products or product rights from other companies. We cannot assure you that we will successfully develop any new products. Further, in developing new products, we will incur additional research and development and marketing expenses and, if acquired from another company, additional expense associated with acquisition and integration of these products into our existing business. Our success in this area will depend upon cost effective development of new products. Revenues, if any, which we generate from new products may not be sufficient to recoup the expenses we will incur in the

Table of Contents

development of new products. Consumers may be slow to accept our new products, if at all, and therefore, we cannot assure you that we will generate sales from any new products we develop. If we cannot successfully develop new products and achieve sales of our new products, our financial performance and results of operations will be adversely affected.

If our domestic or international intellectual property rights are not adequately protected, others may offer products similar to ours which could depress our product selling prices and gross profit margins or result in loss of market share.

We believe that protecting our proprietary technology is important to our success and competitive positioning. In addition to common law intellectual property rights, we rely on patents, trade secrets, trademarks, copyrights, know-how, license agreements and contractual provisions to establish and protect our intellectual property rights. However, these legal means afford us only limited protection and may not adequately protect our rights to keep any advantages we may have over our competitors.

Others may independently develop the same or similar technologies incorporated into our products, including technologies relating to external nasal dilator products, even if these technologies are the subject of our patents, patent applications or licenses. We have a license to the exclusive worldwide rights to manufacture and sell nasal strips in its various versions. We own the patents and pending patents relating to the chewable fiber tablet. Although we believe that our owned and licensed patents will limit the ability of others to introduce competitive products in the United States, there can be no assurance that the patents on the nasal strip or the chewable fiber tablet, or any additional patents on these or other products that may be issued in the future, if any, will effectively prevent the development or sale of competitive products or that we will have sufficient resources to pursue enforcement of any patents issued.

Additionally, we have engaged in litigation to enforce our patent rights relating to our nasal strip technologies. In 1999, we brought suit in federal district court to enforce our rights under U.S. Patent No. 5,533,499 (the “ ‘499 Patent”), one of the licensed nasal strip patents containing the broadest claims relating to the nasal strip. In the course of this suit, the defendant requested reexamination in the U.S. Patent and Trademark Office (the “Patent Office”) of the claims of the ‘499 Patent and on January 21, 2005, we received a determination from the Patent Office that the ‘499 Patent has significant allowable claims. We are seeking, with the licensor of the ‘499 Patent, to amend certain claims of the ‘499 Patent to provide us with additional protection under the ‘499 Patent. We believe that the allowable claims of the ‘499 Patent, if and when reissued, will enable us to maintain significant patent protection for our nasal strip products.

In February 2004, we, together with Creative Integration & Design, Inc., sued Silver Eagle Labs, Inc. (“Silver Eagle”) in the United States District Court for the District of Minnesota for infringement of two nasal dilator patents owned by Creative Integration & Design, Inc. and exclusively licensed to us. The two patents at issue are U.S. Patent No. 6,318,362 (the “ ‘362 Patent”) and U.S. Patent No. 3,533,503 (the “ ‘503 Patent”). The suit seeks injunctive relief, damages, enhanced damages for willful infringement, attorneys’ fees and costs. Silver Eagle has counterclaimed for a declaration that the ‘362 Patent and ‘503 Patent are invalid and not infringed and asks for its attorneys’ fees and costs. In the course of this suit, Silver Eagle requested reexamination of the ‘362 Patent and the ‘503 Patent. In response to the reexamination by the Patent Office, on November 29, 2004, the Court issued an order staying our suit against Silver Eagle pending the reexamination. While the Patent Office has indicated that it has completed its reexamination process with respect to the ‘362 Patent, with the claims of this Patent not being altered or amended in any way, the Patent Office has not formally reissued the ‘362 Patent. An adverse ruling from the Patent Office would narrow the protection available for nasal dilators, limit the breadth of our patent protection and may increase the likelihood that competitors will introduce competitive external nasal dilator products.

On April 13, 2006, we, together with Creative Integration & Design, Inc., sued JMS Labs Limited, LLC (“JMS”) in the United States District Court for the District of Minnesota for infringement of the ‘362 Patent. The suit seeks injunctive relief, damages, enhanced damages for willful infringement, attorneys’ fees and costs.

Table of Contents

Further, our competitors, many of which have substantial resources and may make substantial investments in competing technologies, may apply for and obtain patents that will prevent, limit, or interfere with our ability to manufacture or market our products. While we do not believe that any of our products or processes interfere with the rights of others, third parties may nonetheless assert patent infringement claims against us in the future.

Additional costly litigation may be necessary to enforce patents issued to us, to protect trade secrets or “know-how” we own, to defend us against claimed infringement of the rights of others or to determine the ownership, scope, or validity of our proprietary rights and the rights of others. Any claim of infringement against us may involve significant liabilities to third parties, could require us to seek licenses from third parties, and could prevent us from manufacturing, selling, or using our products. The occurrence of this litigation, or the effect of an adverse determination in any of this type of litigation, could have a material adverse effect on our business, financial condition and results of operations. Further, the laws of some of the countries in which our products are or may be sold may not protect our products and intellectual property to the same extent as the United States or at all. Our failure to protect or enforce our intellectual property rights could have a material adverse effect on our business, results of operations and financial condition.

Our markets are highly competitive and many of our competitors have substantial resources. Competition may result in price reductions, lower gross profits and loss of market share.

We face significant competition in developing and selling our nasal decongestant products and dietary fiber supplement products in both the U.S. and in foreign markets. Our Breathe Right nasal strip, Breathe Right Snore Relief throat spray and Breathe Right Snore Relief Throat Rinse compete in the consumer market with decongestant products and other cold, allergy and sinus relief products consisting primarily of pharmaceutical products sold over the counter, nasal sprays and other external nasal dilators, throat sprays, herbs, supplements and homeopathic remedies. Additionally, we compete with prescription nasal decongestants. We compete with these other products on the basis of numerous factors including brand recognition, product quality, efficacy, price and product availability at the retail store. If consumers perceive any product that competes with ours as more effective, more reliable, less expensive or having other advantages, the demand for our products could decrease.

Although we are currently the leading manufacturer of external nasal dilation products, Schering Plough Corp. entered the market in September 1998 with an external nasal dilation device. In May 2003, Aso Corp. announced it was acquiring the marketing, sales and distribution of Schering Plough’s nasal strip device. Other companies have also entered the nasal dilation market with private label products.

Our FiberChoice product competes with Metamucil® manufactured by Proctor and Gamble, Citrucel® manufactured by GlaxoSmithKline, Benefiber® manufactured by Norvartis and FiberCon® manufactured by Wyeth.

We cannot assure you that we will be able to compete successfully against our current or future competitors. Many of our competitors are significantly larger than we are and have greater financial, technical, research, marketing, sales, distribution and other resources than we do. Additionally, large, well-known, well-financed companies may enter into our markets. Increased competition from other companies may force us to reduce the prices of our products, decrease our gross profit margins, increase discounts to distributors and result in loss of our market share and could require increased spending by us on research and development and sales and marketing.

We rely on third-party manufacturers for our products. Our Breathe Right nasal strip is manufactured by a single-source manufacturer. The raw materials for our Breathe Right nasal strip are being supplied by a single-source supplier. Any failure of these parties to deliver our products or raw materials would cause delays, increase our costs or prevent us from completing customer orders.

Table of Contents

Our Breathe Right nasal strips are manufactured for us by a single manufacturer using a unique raw material supplied by a single supplier, 3M Company. Other raw materials for the nasal strip are available from multiple suppliers. Our other Breathe Right brand products and our FiberChoice products are manufactured for us by a limited number of manufacturers using raw materials supplied by multiple suppliers. If 3M Company is unable to ship the critical raw materials for our Breathe Right nasal strip, our manufacturers would be unable to manufacture our products, and therefore CNS would be unable to ship products to our customers and distributors. If the price of raw materials increases for any reason, or if our suppliers are unable or unwilling to deliver raw materials, we may have to find an alternative source, which could result in interruptions, increased costs, delays, loss of sales and quality control problems. Further, if our manufacturers were unable to manufacture our products for any reason, our customers and distributors would experience delays in receipt of orders of our product. The termination or interruption of any of these relationships, or the failure of these manufacturers or suppliers to supply products or materials consistent with our requirements as to quality, quantity and timeliness, likely would cause shortages of our products, delays in fulfilling orders for our products and harm our reputation and our business by causing delays, loss of sales, increases in costs and lower gross profit margin.

Our sales will decline and our business will be materially harmed if there is any loss of any significant retailer or any reduction, delay or cancellation of orders from any significant retailer.

Our retail customers include national chains of mass merchants, drug stores and grocery stores, warehouse clubs and regional and independent stores in the retail channels. For the fiscal years ended March 31, 2006, 2005 and 2004, Wal-Mart Corporation accounted for approximately 31%, 31% and 32% of our sales, respectively. The loss of this customer or any other large retailer would have a negative impact on our operating results. While we would attempt to replace the lost sales through other retail outlets, we cannot be certain that we would be able to replace any lost sales. Because we typically do not enter into long-term contracts with our customers but rather fulfill demand for our products upon individual sales orders, our customers could cease buying our products from us at any time and for any reason. The loss of any major retailer would disrupt distribution of our products and result in a loss of revenue. If a significant number of our customers cease purchasing products from us, our business would be materially and adversely harmed. Further, any significant reduction or delay in the historical level of orders from our customers, cancellation of orders from any significant retailer or any significant decrease in our retail display space in any of these customers’ stores would have a negative impact on our operating results.

We sell a significant portion of our products internationally, which exposes us to risks associated with foreign operations.

We sell a significant amount of our products to customers outside the United States, particularly in Europe and Asia. International sales accounted for 15%, 14%, and 15% of our revenue for the fiscal years ended March 31, 2006, 2005 and 2004, respectively. We expect that shipments to international customers, including customers in Europe and Asia, will continue to account for a significant portion of our net sales. Sales outside the United States involve the following risks, among others:

•

foreign governments may impose tariffs, quotas and taxes;

•

the demand for our products will depend, in part, on local economic health;

•

expense in developing advertising and marketing campaigns targeted to consumers in foreign countries;

•

political and economic instability may reduce demand for our products;

•

potentially limited intellectual property protection in certain countries may limit our recourse against infringing products or cause us to refrain from selling our products in certain markets;

•

regulatory restrictions may require additional qualification or testing, resulting in further cost and delay in reaching the related markets;

Table of Contents

•

we may face difficulties in managing our international distributors, customers or service partners;

•

the burden and cost of complying with a variety of foreign laws;

•

we may be exposed to fluctuations in foreign currency exchange rates;

•

our contracts with foreign distributors and resellers cannot fully protect us against political and economic instability;

•

we may face difficulties in collecting receivables; and

•

we may not be able to control our international distributors’ efforts on our behalf.

While most of our sales are made in U.S. dollars, some are conducted in the local currencies of foreign countries. These foreign currencies are translated into U.S. dollars for the balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using a weighted average exchange rate during the fiscal year. Gains and losses resulting from transactions denominated in foreign currencies are included in our consolidated statements of operations. Currency fluctuations may adversely affect our financial performance and also may increase the relative price of our product in foreign markets and thereby could also cause our products to become less affordable or less price competitive than those of foreign manufacturers. These risks associated with foreign operations may have a material adverse effect on our revenue from, or costs associated with, international sales.

Our business and our products are subject to governmental regulation, which could have a significant negative effect upon our business.

Nasal dilators, such as our Breathe Right nasal strips, have been classified by the Food and Drug Administration (“FDA”) as Class I medical devices. Our Breathe Right nasal strip products are subject to extensive regulation regarding manufacturing, packaging, labeling, distribution, importation, sale and storage by various federal agencies, including the FDA, the Federal Trade Commission (the “FTC”), the Consumer Product Safety Commission, the Environmental Protection Agency and by various agencies of the states, localities and foreign countries in which our products are manufactured, distributed and sold.

Our FiberChoice dietary fiber supplement is in a category of products commonly referred to for regulatory purposes as “dietary supplements.” Under the Dietary Supplement Health and Education Act (“DSHEA”), dietary supplements are not subject to pre-market approval by the FDA. However, the manufacturing, packaging, labeling, advertising, distribution and sale of dietary supplement products is subject to regulation by federal, state and local governmental agencies, including the FDA and the FTC. Among other matters, regulation by the FDA and FTC is concerned with product safety and claims made with respect to a product’s ability to provide health-related benefits.

Our third-party manufacturers are also subject to governmental regulation in the manufacture of our products, including compliance with rules regarding packaging, labeling and manufacturing practices and equivalent state and foreign regulations. Our manufacturers are subject to periodic inspection to determine if they are complying with the rules regarding packaging, labeling and manufacturing.

Furthermore, we also are subject to a variety of other regulations in various foreign markets, including regulations pertaining to import/export regulations. To the extent we decide to commence or expand operations in additional countries, government regulations in those countries may prevent or delay entry into or expansion of operations in those markets. In addition, our ability to sustain satisfactory levels of sales in our markets is dependent in significant part on our ability to introduce additional products into the markets. However, government regulations in both our domestic and international markets can delay or prevent the introduction, or require the reformulation or withdrawal, of some of our products.

Our failure or the failure of our manufacturers to comply with local, state, federal or foreign regulations could lead to the imposition of significant civil and criminal fines, product recalls, detentions, seizures, injunctions and criminal prosecutions, suspension of product sales or manufacturing, changes in product design or formulation, or changes in product labeling, packaging or advertising or require us to take

Table of Contents

other corrective action, any of which would materially adversely affect our business. Further, violation of these regulations or the assertion of a violation of these regulations could have a material adverse effect on our reputation and the reputation of our products, which could materially damage our business.

Further, the regulatory environment in which we operate is continually changing. Future changes in regulations or enforcement policies could impose more stringent requirements on us, compliance with which could adversely affect our business. These changes could also prove beneficial to our competitors and thus, adversely affect our business. In addition, regulations of the FDA and state and foreign laws and regulations depend heavily on administrative interpretations. We cannot assure you that future interpretations made by the FDA, or other regulatory authorities, with possible retroactive effect, will not adversely affect our business, financial condition and results of operations. It is not possible to assess the likelihood that the laws affecting our products and business will change, or to predict whether such changes, if they occur, will have a material effect on us.

Our business of the manufacturing, marketing, and sale of our products involves the risk of liability claims and such claims could seriously harm our business, particularly if our insurance coverage is inadequate.

Our business exposes us to potential product liability claims that are inherent in the testing, production, marketing and sale of our products. Like other participants in these markets, we may from time to time be involved in lawsuits, claims and proceedings alleging product liability and related claims such as negligence. If product liability claims become substantial, our brands could be damaged significantly, thereby harming our business. We may be required to pay substantial damage awards as a result of any successful product liability claims. Any product liability claim against us, whether with or without merit, could result in costly litigation, and divert the time, attention, and resources of our management.

As a result of our exposure to product liability claims, we currently carry product liability insurance covering our products with policy limits per occurrence and in the aggregate that we have deemed to be sufficient. We cannot predict, however, whether this insurance is sufficient, or if not, whether we will be able to obtain sufficient insurance to cover the risks associated with our business or whether such insurance will be available at premiums that are commercially reasonable. In addition, these insurance policies must be renewed annually. Although we have been able to obtain product liability insurance, such insurance may not be available in the future on acceptable terms, if at all. A successful claim against us or settlement by us in excess of our insurance coverage or our inability to maintain insurance in the future could have a material adverse effect on our business, results of operations, liquidity and financial condition.

If we are required to, or voluntarily, recall our products, our brands and our business could be materially harmed.

The U.S. Food and Drug Administration and similar governmental authorities in other countries in which our products are sold, have the authority to request and, in some cases, require the recall of our products in the event of material deficiencies or defects in design or manufacture. A government-mandated or voluntary recall by us could occur as a result of product functionality, manufacturing errors or design defects. Any recall of product would divert managerial and financial resources, harm our brands and reputation with our customers and damage our business.

Fluctuations in our future operating results may negatively affect the market price of our common stock.

We have experienced fluctuations in our quarterly operating results and we expect those fluctuations to continue due to a variety of factors. Some of the factors that influence our quarterly operating results include:

Table of Contents

•

seasonality of demand for our products;

•

severity of the cold and flu season;

•

timing of the cold and flu season in the United States, Europe and Asia;

•

the number and mix of products sold in the quarter;

•

the availability and cost of materials;

•

timing, costs and benefits of new product introductions;

•

customer order size and shipment timing;

•

promotions by ourselves or competitors, and the timing of the advertising and promotion expense;

•

the impact to the marketplace of competitive products and pricing; and

•

the timing and level of operating expenses.

Because of these factors, our quarterly operating results are difficult to predict and are likely to vary in the future. If our operating results are below financial analysts’ or investors’ expectations, the market price of our common stock may fall abruptly and significantly.

We are dependent on key personnel.

Our future success depends, in significant part, upon the continued service and performance of our senior management and other key personnel, in particular Marti Morfitt, our Chief Executive Officer. The loss of Ms. Morfitt’s services could impair our ability to effectively manage our company and to carry out our business plan. We have an employment agreement with Ms. Morfitt that provides that Ms. Morfitt will serve as our Chief Executive Officer and that either party may terminate Ms. Morfitt’s employment at any time with or without cause. However, if we terminate Ms. Morfitt’s employment without cause, we would be required to make specified payments to her as described in her employment agreement. The other members of our management team also have significant experience in our industry. The loss of any member of our senior management could likewise impair our ability to effectively manage our company and carry out our business plan. We do not carry key person life insurance on any of our executive officers. In addition, competition for skilled employees in our industry is intense. Our future success also depends on our continuing ability to attract, retain and motivate highly qualified managerial, technical and sales personnel. Our inability to retain or attract qualified personnel could have a significant negative effect and materially harm our business and financial condition.

Our stock price may be volatile and a stockholder’s investment could decline in value.

Our stock price has fluctuated in the past and may continue to fluctuate significantly, making it difficult for an investor to resell shares or to resell shares at an attractive price. The market prices for securities of companies with relatively small capitalization, like us, have historically been highly volatile. Future events concerning us or our competitors could cause such volatility, including:

•

actual or anticipated variations in our operating results;

•

new innovations in existing products or new products introduced by us or our competitors;

•

developments concerning proprietary rights;

•

changes in senior management;

•

investor perception of us and our industry;

•

general economic and market conditions including market uncertainty;

•

national or global political events; and

•

public confidence in the securities markets and regulation by or of the securities markets.

In addition, the stock market is subject to price and volume fluctuations that affect the market prices for companies in general, and small-capitalization, high-technology companies in particular, which are often unrelated to the operating performance of these companies. In addition to fluctuations unrelated to our financial performance, our failure to meet expectations of financial analysts and investors will likely cause a decline in the price of our common stock.

Table of Contents

Future sales of shares of our common stock in the public market may negatively affect our stock price.

Future sales of our common stock, or the perception that these sales could occur, could have a significant negative effect on the market price of our common stock. In addition, upon exercise of outstanding options and warrants, the number of shares outstanding of our common stock could increase substantially. This increase, in turn, could dilute future earnings per share, if any, and could depress the market value of our common stock. Dilution and potential dilution, the availability of a large amount of shares for sale, and the possibility of additional issuances and sales of our common stock may negatively affect both the trading price of our common stock and the liquidity of our common stock. These sales also might make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that we would deem appropriate.

Provisions of Delaware law, our bylaws and other agreements may deter a change of control of us and may have a possible negative effect on our stock price.

Certain provisions of Delaware law, our bylaws and other agreements may make it more difficult for a third party to acquire, or discourage a third party from attempting to acquire, control of us, including:

•

the provisions of Delaware law relating to business combinations and control share acquisitions;

•

the provisions of our bylaws regarding the business properly brought before stockholders;

•

the right of our board of directors to establish more than one class or series of shares and to fix the relative rights and preferences of any such different classes or series; and

•

the provisions of our stock option plans allowing for the acceleration of vesting or payments of awards granted under the plans in the event of specified events that result in a “change in control” and provisions of agreements with our executive officers requiring payments if their employment is terminated and there is a “change in control.”

These measures could discourage or prevent a takeover of us or changes in our management, even if an acquisition or such changes would be beneficial to our stockholders. This may have a negative effect on the price of our common stock.

LEGAL PROCEEDINGS

On February 18, 2004, CNS, Inc. (the “Company”), together with Creative Integration & Design, Inc., sued Silver Eagle Labs, Inc. (“Silver Eagle”) in the United States District Court for the District of Minnesota for infringement of two nasal dilator patents owned by Creative Integration & Design, Inc. and exclusively licensed to the Company. The two patents at issue are U.S. Patent No. 6,318,362 (the “ ‘362 Patent”) and U.S. Patent No. 3,533,503 (the “ ‘503 Patent”). The suit seeks injunctive relief, damages, enhanced damages for willful infringement, attorneys’ fees and costs. Silver Eagle has counterclaimed for a

Table of Contents

declaration that the ‘362 Patent and ‘503 Patent are invalid and therefore not infringed and asks for its attorneys’ fees and costs.

On November 24, 2004, the Company announced that the U.S. Patent and Trademark Office (the “Patent Office”) will reexamine the ‘362 Patent and the ‘503 Patent. In response to this action by the Patent Office, on November 29, 2004, the Court issued an order staying the Company’s suit against Silver Eagle pending the reexamination. The Company believes that when the ‘362 and ‘503 Patents emerge from reexamination, the Company will maintain significant patent protection under those patents and will recommence enforcement of those patents in the litigation described above.

On April 13, 2006, the Company, together with Creative Integration & Design, Inc., sued JMS Labs Limited, LLC (“JMS”) in the United States District Court for the District of Minnesota for infringement of the ‘362 Patent. The suit seeks injunctive relief, damages, enhanced damages for willful infringement, attorneys’ fees and costs.

As of the date of filing of this Annual Report on Form 10-K for the year ended March 31, 2006, the Patent Office has not granted a Reexamination Certificate for either the ‘362 Patent or the ‘503 Patent. The Patent Office has indicated that the reexamination process with respect to the ‘362 Patent has been terminated, with the claims of the Patent not being altered or amended in any way.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of the financial condition and results of operations should be read in conjunction with the audited consolidated financial statements and notes thereto appearing elsewhere in this Annual Report. In this discussion, our three fiscal years ended March 31, 2006, 2005 and 2004 are referred to as fiscal years 2006, 2005 and 2004, respectively.

Growth Strategy and Financial Focus

We are in the business of developing and marketing consumer health care products, including Breathe Right® branded products focused on better breathing, and FiberChoice® branded products focused on digestive health. We operate in niche categories of the large over-the-counter health care market with unique product offerings that are supported by strong advertising and promotion programs. Our competitive strengths include our brands, patented technologies, established domestic and international distribution networks, a flexible and low-cost operating model and an experienced management team.

Our financial goals are to achieve sustainable long-term growth in consumer demand for our products, which should leverage our efficient operating model to generate further growth in operating profit and operating cash flow:

•

Sustainable Growth in Consumer Demand. During the three fiscal years ended March 31, 2006, consolidated net sales have grown from $87.0 million to $112.6 million. During this same three year period, net sales of domestic Breathe Right products have grown from $64.1 million to $74.6 million, net sales of FiberChoice products have grown from $9.3 million to $20.8 million, and net sales of international Breathe Right products have increased from $13.0 million to $17.0 million.

•

Operating Profit. During the past three fiscal years, we have grown operating profit at a rate which exceeds the growth rate of net sales. This has been achieved through the increased efficiency of our advertising and promotional campaigns and improvement in our gross profit rate, resulting from continued reductions in cost of goods sold and stronger growth of higher margin items within our product mix.

•

Operating Cash Flow. We are also focused on growing operating cash flow primarily through sustainable growth in revenue and net income, as well as continued focus on maintaining an efficient level of working capital. We are adept at managing an efficient operating model which requires limited capital expenditures to support our current business.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles (GAAP) in the United Sates of America. In connection with the preparation of the consolidated financial statements, we are required to make assumptions and estimates about future events, and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time the consolidated financial statements are prepared. On a quarterly basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure our financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material.

Table of Contents

Our significant accounting policies are discussed in Note 1, Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements, included in Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K. We believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult and subjective judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain. We have reviewed these critical accounting policies and estimates with the Audit Committee of our Board of Directors.

•

Revenue Recognition, Sales Returns and Other Allowances, and Allowance for Doubtful Accounts. Revenue is recognized when all of the following criteria have been met: a valid customer order with a fixed price has been received; title and risk of loss transfer to the customer; there is no further significant obligation to assist in the resale of the product; and collectibility is reasonably assured. Revenue is reduced for trade promotions, estimated future product returns, certain promotional costs and other allowances in the same period as the related sales are recorded. We must make estimates of potential future product returns and other allowances related to current period revenue. We analyze historical returns, current trends, and changes in customer and consumer demand when evaluating the adequacy of the sales returns and other allowances. We have established reserves of $1.3 million for future sales returns and $311,000 for other allowances as of March 31, 2006. Similarly, we must make estimates of the uncollectability of accounts receivable. We specifically analyze customer account balances, historical bad debts, current economic trends and changes in the timing of customer payments. The balance of accounts receivable was $17.7 million, net of the allowance for doubtful accounts of $100,000, as of March 31, 2006.

•

Inventory Valuation. Inventory is valued at the lower of cost, determined on a first-in, first-out basis (FIFO), or market. We analyze the cost and the market value of inventory items and establish the appropriate valuation reserves. We have established a reserve for excess or obsolete inventory of $532,000 as of March 31, 2006. We believe that the inventory valuation results in carrying inventory at the lower of cost or market.

•

Accounting for Income Taxes. As part of the process of preparing financial statements, we are required to estimate income taxes, both state and federal. This process involves estimating the actual current tax exposure together with assessing temporary differences resulting from different treatment for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the consolidated balance sheet. We then assess the likelihood that deferred tax assets will be utilized to offset future taxable income during the periods in which these temporary differences are deductible. Based on the level of historical taxable income and projections of future taxable income for the periods in which the deferred tax assets are deductible, we believe that it is more likely than not that CNS will realize the benefits of these deductible differences.

•

Trade and Consumer Promotions. Our judgment is involved in recognizing the amount and timing of trade and consumer promotional costs. Management regularly reviews current period and prior period promotional liabilities and assesses customers’ and consumers’ participation and performance levels related to various promotional activities. The vast majority of year end liabilities associated with these activities are resolved within the following fiscal year, and therefore do not require highly uncertain long-term estimates. We have established a liability for trade and consumer promotions of $1.2 million as of March 31, 2006.

Selected Consolidated Statements of Earnings Data and Executive Summary

For the fiscal year ended March 31, 2006, (“fiscal 2006”) net sales increased by 20.2% versus the prior year to $112.6 million. The increase in net sales reflects strong growth for both Breathe Right and FiberChoice brands. Breathe Right domestic net sales grew by 9.1%; FiberChoice net sales increased 70.2% and international Breathe Right net sales increased by 31.9%. Domestic Breathe Right experienced strong

Table of Contents

growth in nasal strips and Snore Relief™ throat spray partially offset by declining sales of Vapor Shot!™ and saline spray, which are being phased out. Net sales of FiberChoice branded products continued to grow as the result of growing consumer demand driven by expanded advertising programs and the introduction of two additional fiber products. International net sales growth resulted from strong sales to Canada and the UK, as well as resumption of normalized sales to Japan. In the first eight months of fiscal 2005, no revenues were recorded in Japan due to high inventory levels in that market.

Operating income for fiscal 2006 was $25.6 million, up 27.7% versus the prior year. Growth in operating income was driven by 20.2% revenue growth combined with improvements in advertising and promotion efficiencies and improvement in selling, general and administrative expense as a percentage of sales partly relating to a decrease in litigation costs involving patent defense. Operating income for fiscal 2005 reflects a one-time reduction in cost of goods sold of $1.1 million, related to the refund of import duties paid in prior fiscal years.

Our financial position remains strong, with cash and marketable securities of $52.6 million and no debt on our balance sheet as of March 31, 2006.

We believe the percentage relationship between net sales and major expense lines in the statement of operations and the percentage change in the dollar amounts of each of the items presented below is important in evaluating the performance of our business operations. We operate as one business segment and believe the information presented in our Management’s Discussion and Analysis of Results of Operations and Financial Condition provides an understanding of our business, operations and financial condition.

Operating results

Net sales grew by 20.2% in fiscal 2006 and 7.8% in fiscal 2005. Domestic sales of Breathe Right branded products grew by 9.1% in fiscal 2006 due primarily to stronger consumer demand for nasal strips and Snore Relief throat spray partially offset by declining sales Breathe Right Vapor Shot! and saline spray. FiberChoice sales grew by 70.2% in fiscal 2006 and 31.8% in fiscal 2005. The fiscal 2006 growth in FiberChoice sales resulted from continued growth in consumer demand driven by strong levels of advertising and promotion and the launch of two new FiberChoice products during the March 2006 quarter, FiberChoice® plus Calcium and FiberChoice® Weight Management.

International sales increased in fiscal 2006 by 31.9% to $17.0 million. International net sales growth resulted from strong sales to Canada and the UK, as well as resumption of normalized sales to Japan. In the first eight months of fiscal 2005, no revenues were recorded in Japan due to high inventory levels in that market.

During fiscal 2004, we decided to exit our line of Flair equine products which are included in “other” on the net sales breakdown, shown on the prior page. The Company has terminated its agreements with its distributor of Flair products and the licensor of technology related to this business, effective April 30, 2004. Net sales of Flair products totaled $375,000 for fiscal 2004.

Gross profit rate

Gross profit rate is dependent on a number of factors and may fluctuate from quarter to quarter as well as year to year. These factors include the mix of products sold, the level of promotional activity, and the cost of materials and manufacturing. The gross profit rate for fiscal 2006 was 70.5%. Excluding a one-time reduction to cost of goods sold related to an import duty refund of $1.1 million, the fiscal 2005 gross margin rate was 70.3%. The continued improvement in gross margin rates in 2006 and 2005 resulted primarily from lower cost of sales including increasing efficiency in procuring and distributing our product lines.

Table of Contents

Advertising and promotion expense

Advertising and promotion expense expressed as a percentage of revenue declined to 31.0% in fiscal 2006, down 0.7 percentage points compared to fiscal 2005, which was down 5.3 percentage points compared to fiscal 2004. This reduction in expense as a percentage of net sales is the result of economies of scale driven by growth of our brands, as well as continuing efforts by our marketing team to develop more efficient and effective methods of stimulating consumer demand.

Selling, general and administrative expense

Selling, general and administrative expenses were $18.9 million for 2006, representing an increase of 9.4% compared to the prior year. Selling, general and administrative expense increased in fiscal 2006 due to higher levels of new product development expense for both the Breathe Right and FiberChoice brands, as well as increased employee costs. Selling, general and administrative expense as a percentage of net sales was 16.8%, 18.4% and 17.4% for the fiscal years 2006, 2005 and 2004, respectively. The increased expense rate for fiscal 2005 is the result of increased legal expenses associated with defending our intellectual property assets.

Operating income

Increases in sales, continued improvements in gross profit rates and continued improvement in the efficiency of advertising and promotions provided significant improvement in operating income. Operating income for fiscal 2006 was $25.6 million, up 27.7% compared to fiscal 2005 operating income of $20.1 million which increased 57.3% compared to fiscal 2004 operating income of $12.7 million. Operating income as a percentage of net sales is 22.7%, 21.4% and 14.7% for fiscal 2006, 2005 and 2004, respectively.

Investment income

Investment income increased to $1.2 million for fiscal 2006 compared to $935,000 for fiscal 2005 as the result of an increase in market interest rates for municipal obligations. The Company continues to shift the investment portfolio to tax-exempt securities in order to maximize after tax yields. The following table compares the average bond equivalent yield of various marketable securities held as of March 31, 2006 and 2005 (in thousands):

	March 31,
	2006				2005
		Fair Value	Ave. Yield			Fair Value	Ave. Yield

Municipal obligations	$	46,438	3.89	%	$	41,358	2.86	%
Corporate bonds		1,001	2.52			6,064	2.03
U.S. Government obligations		1,000	2.42			8,514	1.82
Total marketable securities	$	48,439	3.82	%	$	55,936	2.66	%

The average remaining days to effective maturity of the Company’s portfolio of marketable securities has decreased to 215 days as of March 31, 2006 compared to 303 days as of March 31, 2005.

Income tax expense

Income tax expense was $9.6 million for fiscal 2006 compared to $7.3 million for fiscal 2005. The effective tax rate for fiscal 2006 was 35.7% compared to an effective tax rate in fiscal 2005 of 34.7%. The 1.0 percentage point increase in the effective tax rate is primarily the result of a favorable resolution of refund claims in fiscal 2005 and a decrease in the benefit relating to foreign export incentives partially offset by an increase in investment income related to tax exempt securities. Refer to the following effective tax rate reconciliation table:

Export incentive	(.1)		(0.5)
Other	.2		(0.9)
Effective tax rate	35.7	%	34.7	%

Seasonality

CNS has experienced in the past, and expects that it will continue to experience in the future, quarterly fluctuations in both domestic and international sales and earnings. These fluctuations are due in part to the timing of advertising and promotion campaigns and seasonality of sales, as well as increases and decreases in purchases by distributors and retailers in anticipation of future demand by consumers. Significant portions of the Breathe Right product line are used for the temporary relief of nasal congestion and congestion-related snoring. Sales of these items are higher during the fall and winter seasons, corresponding with our third and fourth quarters.

Liquidity and capital resources

As of March 31, 2006, we have cash and marketable securities of $52.6 million and no debt on our balance sheet. In addition, we have generated strong and improving cash from operations during the past three fiscal years, and barring an unforeseen decline in our revenues or operating margins, we expect future cash flows from operations to continue to be strong and growing. The existing cash and marketable securities balances may be used to acquire complementary consumer healthcare businesses, pay dividends to our shareholders and/or buy back additional shares of CNS common stock. In summary, we believe that our existing funds will be sufficient to support our planned operations for the foreseeable future.

Operating activities. We generated cash from operating activities of $15.8 million during fiscal 2006 compared to $14.7 million and $8.6 million during fiscal 2005 and 2004, respectively. The improved net cash provided by operations is primarily due to the increases in operating income described above partially offset by increases in accounts receivable and inventories required to support our sales growth.

Investing activities. During fiscal 2006, we continued to invest excess cash in short term marketable securities in order to improve our investment return. Sales and maturities of marketable securities exceeded purchases by $7.6 million for fiscal 2006. The proceeds from the investment portfolio along with cash provided by operations were used to purchase product rights, repurchase CNS common stock and pay cash dividends. For 2006, marketable securities purchased consisted of tax exempt municipal securities which provide a higher after tax yield.

We purchased $8.0 million, $557,000 and $310,000 of product rights during fiscal 2006, 2005 and 2004, respectively. In fiscal 2006, we purchased the patents and pending patents relating to the FiberChoice chewable fiber tablet from Onesta Nutrition, Inc. for $7.8 million. The previous licensing agreement with Onesta Nutrition, Inc. was terminated as part of the purchase transaction.

Financing activities. We paid cash dividends of $3.4 million, $2.8 million and $1.6 million during fiscal 2006, 2005 and 2004, respectively. In making the decision to initiate a cash dividend, the Company’s Board of Directors considered, among other things, the favorable tax treatment of corporate dividends.

We purchased 655,105 shares of our common stock for $13.9 million during fiscal 2006. The average price of common stock purchased was $21.26 per share. We purchased 106,000 shares of our common stock for $1.4 million during fiscal 2005. We did not repurchase any shares of our common stock in fiscal 2004. These treasury shares will be used to meet future obligations under our employee stock purchase plan and stock option plans, and for possible future acquisitions. CNS is authorized to repurchase an additional 770,400 shares of its common stock as of March 31, 2006.

Table of Contents

CNS received $1.9 million, $1.9 million and $1.8 million during fiscal 2006, 2005 and 2004, respectively, from the exercise of stock options and issuance of stock under the employee stock purchase plan.

Significant agreements and lease obligations. We have entered into certain agreements and operating leases in order to secure product rights and office space. The following is a summary of significant agreements and lease obligations (in thousands):

		Payments Due by Period Fiscal Year
		2007		2008		2009		2010		2011		Thereafter

Operating leases	$	788	$	788	$	788	$	745	$	494	$	0

Total	$	18,142	$	1,360	$	1,338	$	1,295	$	1,044

We have agreements that exclusively license intellectual property rights for certain products. Royalties due under these agreements are based on various percentages of sales of related product lines. The licensing agreements are valid for the lives of the related patents, however, they may be terminated earlier under certain conditions. Total minimum royalties are not determinable since royalties continue for the life of current and potential future patents related to the licensed intellectual property.

We have entered into operating leases for office space and office equipment. Leases expire at various dates beginning in 2010 through 2011.

Management is not aware of any significant agreements or obligations that would have a material negative impact upon the Company’s short-term or long-term liquidity.

Recent accounting pronouncements

In December 2004, the FASB issued SFAS 123R, “Share-Based Payment: an amendment of FASB Statements No. 123 and 95”, which requires companies to recognize in the statement of operations the grant-date fair value of stock options and other equity-based compensation issued to employees. The provisions of the interpretation are effective for the Company’s consolidated financial statements for periods beginning April 1, 2006.

The Company anticipates using the modified prospective application, which applies to new awards granted, unvested awards as of the date of adoption and to awards modified, repurchased or cancelled after the date of adoption. SFAS 123R focuses primarily on accounting for transactions in which an entity obtains employee services through stock–based payment transactions. SFAS 123R requires measurement of the cost of employee services received in exchange for the award of equity instruments based on the fair value of the award as of the date of grant.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that:

(i)

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

(ii)

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

(iii)

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control-Integrated Framework, our management concluded that our internal control over financial reporting was effective as of March 31, 2006.

Our management’s assessment of the effectiveness of our internal control over financial reporting as of March 31, 2006, has been audited by KPMG LLP, the independent registered public accounting firm that audited the consolidated financial statements in this Form10-K, as stated in their report, which is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Board of Directors and Stockholders

CNS, Inc.:

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Controls Over Financial Reporting that CNS, Inc. maintained effective internal control over financial reporting as of March 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). CNS, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

In our opinion, management’s assessment that CNS, Inc. maintained effective internal control over financial reporting as of March 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, CNS, Inc. maintained, in all material respects, effective internal control over financial reporting as of March 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CNS, Inc. and subsidiaries as of March 31, 2006 and 2005, and the related consolidated statements of operations, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended March 31, 2006, and our report dated May 31, 2006 expressed an unqualified opinion on those consolidated financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON
CONSOLIDATED FINANCIAL STATEMENTS AND FINANCIAL STATEMENT SCHDULE II

The Board of Directors and Stockholders

CNS, Inc.:

We have audited the accompanying consolidated balance sheets of CNS, Inc. and subsidiaries as of March 31, 2006 and 2005, and the related consolidated statements of operations, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended March 31, 2006. In connection with our audits of the consolidated financial statements, we also have audited financial statement schedule II- Valuation and Qualifying Accounts. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement 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. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. 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 CNS, Inc. and subsidiaries as of March 31, 2006 and 2005, and the results of their operations and their cash flows for each of the years in the three-year period ended March 31, 2006, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of CNS Inc.’s internal control over financial reporting as of March 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated May 31, 2006 expressed an unqualified opinion on management’s assessment of, and the effective operation of, internal control over financial reporting.

Notes to Consolidated Financial Statements

March 31, 2006, 2005 and 2004

Summary of Significant Accounting Policies

Business The Company develops and markets consumer health care products, including Breathe Right® branded products focused on better breathing, and FiberChoice® branded products focused on digestive health. Theses products are sold over-the-counter in retail outlets, including mass merchant, drug, grocery, club stores, military base stores and on-line retailers. The Company primarily uses international distributors to market Breathe Right nasal strips outside the U.S.

Principles of Consolidation The accompanying consolidated financial statements include the accounts of CNS, Inc. and its subsidiaries (“the Company”). All material intercompany accounts and transactions have been eliminated in consolidation.

Accounting Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s estimates and assumptions primarily arise from risks and uncertainties associated with potential future product returns, settlement of trade and consumer promotion liabilities, the uncollectibility of accounts receivable, inventory obsolescence and realization of deferred tax assets.

Basis of Presentation Certain amounts from prior years’ consolidated financial statements have been reclassified to conform to the current year presentation. Research costs of $831,000 and $933,000 were reclassified from advertising and promotion expense to selling, general and administration expense for the years end March 31, 2005 and 2004.

Revenue Recognition Revenue is recognized when all of the following criteria have been met: a valid customer order with a fixed price has been received; title and risk of loss transfer to the customer; there is no further significant obligation to assist in the resale of the product; and collectibility is reasonably assured. The Company records provisions for trade promotions, returns and customer discounts as a reduction to net sales in the same period that the related sales are recorded.

Fair Value of Financial Instruments Cash, cash equivalents and accounts receivable are carried at amounts that approximate fair value because of the short-term nature of these instruments.

Cash Equivalents Cash equivalents consist primarily of money market funds with original maturities of three months or less.

Marketable Securities The Company classifies its marketable debt securities as available-for-sale and records these securities at fair market value. Marketable securities represent the investment of excess cash that would be available to meet current obligations or fund potential acqusitions.

Net realized and unrealized gains and losses are determined on the specific identification cost basis. Any unrealized gains and losses, net of deferred income taxes, are included in stockholders’ equity as a separate component of other comprehensive income. A decline in the market value of any available-for-sale security below cost that is deemed other than temporary, results in a charge to operations and the establishment of a new cost basis for the security. Realized securities gains or

F-6

Table of Contents

losses are included in gain (loss) on sales of marketable securities in the consolidated statements of operations.

Inventories Inventories are valued at the lower of cost (determined on a first-in, first-out basis) or market. Inventory reserves have been established for potential product obsolescence.

Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Equipment is depreciated using the straight-line method over three to five years. Leasehold improvements are amortized over the lesser of the estimated useful life of the improvement or the term of the lease.

Product Rights Product rights, consisting of patents, trademarks and other product rights, are stated at cost, net of accumulated amortization and are amortized over three to ten years using the straight-line method. The weighted average remaining amortization life is 9.0 years as of March 31, 2006. The Company reviews its product rights for impairment whenever events or changes in circumstances indicate that the carrying amount of a product right may not be recoverable. If such product rights are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the product right exceeds the fair value of that product right.

Stock-Based Compensation The Company accounts for stock-based compensation arrangements in accordance with the provisions of Accounting Principles Board Opinion (“APB”) No. 25, “Accounting for Stock Issued to Employees,” and complies with the disclosure provisions of SFAS 123, “Accounting for Stock-Based Compensation” as amended by SFAS No. 148, “Accounting for Stock-Based Compensation”. Under APB No. 25, compensation cost is determined based on the difference, if any, on the grant date between the fair value of the Company’s stock and the amount an employee must pay to acquire the stock. Accordingly, no compensation expense associated with the fair market value of stock option grants or shares sold to employees under the Employee Stock Purchase Plan has been recognized in the Company’s consolidated financial statements.

The fair value of each stock option grant issued under various stock option plans and shares sold to employees under the Employee Stock Purchase Plan are estimated on the date of grant or purchase using the Black-Scholes option-pricing model. The following weighted average assumptions were made in estimating fair value:

	For the Years Ended

Expected lives (Years)	5.2		4.6		5.7

Had compensation cost for the Company’s stock option plans and Employee Stock Purchase Plan been determined based on the fair value of options at the grant date, net income and earnings per share would have been as follows:

Foreign Currency Transactions Most foreign transactions are denominated in U.S. dollars, although some are conducted in functional local currencies. Gains and losses resulting from transactions denominated in foreign currencies are included in the consolidated statements of operations.

Advertising The Company capitalizes the production costs of advertising and expenses these costs in the period in which the advertising first runs.

Income Taxes Income tax expense includes federal and state income taxes. The provision for income taxes is composed of current income tax expense and the change in the balance of the deferred tax assets and liabilities. Deferred tax assets and liabilities and the resultant provision for income taxes are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are recognized when management determines that it is more likely than not that the asset will be realized.

Net Earnings Per Share Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common and potential common shares outstanding during the period.

Comprehensive Income Comprehensive income consists of the Company’s net income and unrealized gains (losses) on marketable securities and is presented in the consolidated statements of stockholders’ equity and comprehensive income.

Recent Accounting Pronouncements In December 2004, the FASB issued SFAS 123R, “Share-Based Payments: an amendment of FASB Statements No. 123 and 95”, which requires companies to recognize in the statement of operations the grant-date fair value of stock options and other equity-based compensation issued to employees. The provisions of the interpretation are effective for the Company’s consolidated financial statements for periods beginning April 1, 2006.

Net deferred tax assets	$	2,811	$	2,991

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based on the level of historical taxable income and projections of future taxable income over the periods in which the deferred tax assets are deductible, management believes that it is more likely than not the Company will realize the benefits of these deductible differences.
